Root ZTE Grand S2 (S251)

Root ZTE Grand S2 (S251)
This is easiest way to root ZTE grand S2 (S251) Indian version.

1) Get Towelroot apk from towelroot by geohot (Click on lambada sign to download)

2) Install towelroot apk,
-you may have to rename if downloaded file is tr.txt to tr.apk for some reason when downloading on this phone tr.apk got downloaded as tr.txt.
-you will have to disable security to allow install for unknown sources.
-you will have to override Google warning about malicious software.

3) install supersu or superuser from google play store and you are done.

Note:: restart your phone even though it is not required somewhere along when you are installing supersu your phone screen hangs and goes blank. you have to hold power button to force shutdown and wait some time before turning it back on. this happened to me twice. So don't panic if this happens. It will happen only once.

Some recommended root apps, that make rooting worth while..

1) AdAway v2.9.2 - XDA-Developers this modifies your etc/host file to add local loopback to advertisement urls. this diables ads in some apps and save bandwidth (since in india 3G data is expensive and very limited in packs) this helps though bad for devlopers this may save some bucks in data usage.

2) helium from play store - though this works without root but is so much simpler with root.

3) System app remover (ROOT) this is useful for getting rid of some bloatware and taking backup of apps before uninstalling.

4) ES file explorer can be used as root file explorer with rooted phone

5) Clean master also enables some advanced features like phone boost when rooted.

6) Device control / No frills CPU control for some advanced tweakings

7) Terminal for running commands with su access.

ZTE Grand S2 (S251) Screenguard hack.

Screen-guard for ZTE Grand S2 (S251) Indian version.

Presently on 5 Feb 2015 no pre-cut screen guard was available for this phone.
here are 3 simple hacks you can use for the time being until screen-guard is available.

1) use the one which comes pre-installed. 
Instead of being quick to peel of the lamination on the screen use it until you can get a decent replacement. The lamination is covered with some printed stuff from ZTE.

To erase the printed stuff best is nail polish remover.
process: take a little nail polish remover on cotton. (little means just a little bit) use light handed strokes to clean the printing and clean the remaining with dry tissue paper.

2) buy a cheap good quality screen-guard for bigger phones
6 inch ones like Xperia Z ultra , Note 3, I bought AMZER screen guard for LG-Gflex. for 49 bucks from flipkart, other sites like snapdeal, shopclues etc always have some sale going on. take out lamination and stick it on bigger screen-guard. draw outline with a CD-marker of size and cut away excess using sharp-scissors.

Note: You will be tempted to use blade for cutting the screen-guard. but telling you from experience use Scissors , Very sharp one, preferably new ones. trick here is not to destroy the edge else screen-guard will never stick properly. 

Note: if you cannot stick screen-guard in one go. use tape to lift from edge. if some dust particles are stuck between screen-guard and screen use tape again to pick it up. this takes patience and you will be able to install a perfect screen guard with no dust or bubbles.

3) Redmi Note screen guard is closest to ZTE grand S2 which need a very small trimming at edges and over sensor. use redmi note screen guard generally sold for 99 at Flipkart, MRP 179 and I picked 2 in deal of the day for 49 each.

Tip:: use another cheap screen guard for back too. else aluminium finish picks up scratches pretty easily especially if you kept key in the same pocket by mistake. 

Buying Budget Mobile ZTE Grand S2 (S251) Indian Version

I was looking to buy a sub Rs 10,000 mobile, there were many choices presently in Indian market, with strings attached of course.

Requirements:
1) 5" screen or higher
2) main use media consumption and some small games nothing fancy.
3) should be able to root.
4) SD card support of 64gb card

Sub 10 K choices:
=============
1) Redmi Note 3G/4G
2) Yu Yureka
3) ZTE Grand S2 (Sub 10K for 3 days only 24-26th Jan 2015)

1) Redmi Note 

- Cumbersome purchase process
- Snapdragon 400 for 4G is not exactly high performance,
- MTK Chipset was banned for sale in India

+ Excellent Screen Quality
+ High Capacity Battery
+ Availability of accesories
+ Excellent built quality
+ good enough camera

2) Yu Yureka

- After 2 frustrating week of trying to purchase from amazon, I gave up. process is absolutely frustrating and not smooth like flipkart flash sale.

- 64 bit chipset. Android at 64 bit is relatively new and full of bugs, it will iron out in time, but waiting for cyanogen mod to release fixes, makes the experience of this phone pretty bad. (src Amazon customer reviews of Yu Yureka handset)

- I am not sure if 2GB ram is enough of 64 bit , for windows thumb rule is 2gb windows 32, 4gb windows 64 bit considering that its phone OS but still if memory allocations are 64 bit instead of 32 bit won't it use up most of 2GB RAM ? I am yet to use a 64 bit phone so I wish to see its idle memory usage first before plunging into 64 bit/2GB platform.

-none of my friends got this after trying it for 4 weeks now(05, feb2015). This shows how screwed up wastage of time trying to purchase this phone is.

+ high specs on paper
+ CyanogenMod

3) ZTE Grand S2

-not exactly under 10K ( was for 3 days only for republic day sale 3,000 lightening deal discount and 10% discount from HDFC Card) I got this on 24th Jan 2015 for Rs-9,900

-Jellybean 4.2 (no chance of upgrade ever-since this phone is different from that of Chinese market S291 Indian version is S251) so I am not hopeful about development of OS from modaco.com or xdadevlopers.com

- no accessory available (no cases and no screen-guards) whatever is available is for S291 and not for S251

+ GSM, CDMA, UMTS, 3G (dual band - 2.4/5 GHz wifi)
+ Excellent built quality (premium aluminum finish)
+ snapdragon 800 / 2GB /16MB/expandable SD-Card
+ very light phone
+ ZTE UI (some cool shortcuts)
+ NO Fussy sale process, just login to amazon and buy, No invites and no flash sales = frustration free buying experience

will be updating on my experience with ZTE Grand S2 (S251) later on. but this phone at Rs 9900/- is really a very good deal. perhaps this deal will come later on at valentine's day or holi , If anybody is intrested in buying can check amazon for this phone..

Grab drivers from your manufacturers site or OEM sites..
for dell 3446 -> http://www.dell.com/support/home/us/en/19/product-support/product/vostro-14-3446/drivers

download applicable drivers
============================
chip-set (if you are using intel see driver date, you should download latest intel chipset drivers from intel site, for me USB 3 drivers were missing so have to download USB 3 drivers from intel too)
audio (was a realtek chipset, generally i do not care about audio drivers much, you can check realtek site for more recent drivers if you wish)
video (Intel GMA from intel site and Nvidia 820m from Nvidia site since this is a hybrid display so both drivers are needed.)
network (i downloaded NIC drivers and WLAN-bluetooth combo drivers from Dell site..)
serial ata (more recent may be available at intel site, i downloaded from dell site)
mouse, keyboard, input devices (download synaptic bundled drivers from dell site you may find more recent drivers at synaptic site but using dell drivers is advisible)
BIOS (this is tricky if you have no issue upgrading BIOS is not advisable check fix log and decide if you wish to upgrade your BIOS)

I upgraded the Toshiba 500gb HDD to Corsair Force Series LX 256GB which i had from my previous laptop. The present cost is under 10K for this SSD you may find cheaper ADATA or Transdent SSD's
or stick to bundled HDD.

for installing HDD look at back of laptop there will be a hdd sign, remove panel and swap hdd. its rather simple

now plug in USB key and switch on your laptop press boot menu key mine was F12, for some its F10 or F11 just check your laptop manual for boot menu key
select boot from USB device, follow On screen instructions until windows is installed..
when you switch on your laptop boot key will be shown at startup for my laptop it was F2 for BIOS and F12 for boot menu

Once you have installed windows its time to install drivers..
I usually follow these steps
1) install chipset drivers
2) install audio drivers
3) install video drivers (for dell-3446 it was intel GMA first and then Nvidia 820m)
4) install network drivers
and reboot
5) install input devices and hdd drivers
and reboot once more

now right click on my computer and go to device manager check if any driver is missing.
missing / faulty drivers show up with a yellow dot.
if you have some unknown device.. select and go to properties now select details,
select hardware ids from drop down and copy paste that hardware id on Google and search for compatible drivers
or at least name of that hardware device once you know which device has its driver missing you can search for drivers on internet.

i also like to install antivirus early on
my recommendation is Eset-nod 32
and install direct x , visual c++ redistribution and enable windows updates
let windows updates finish, this takes a lot of time.
you can use your computer and install some utilities and software that will make life so much easier..

so check my list of must have utilities for windows install.

Anti-Virus To Buy or Not to Buy

One of the Questions, So frequently asked from my friends and colleagues, if they should invest in anti-virus software lets discuss,

Do I need an Anti-Virus Solution for my PC?

Online Usage: If you frequently go online or always online then yes, you should have an Anti-Virus solution installed on your PC.

Do you need to transfer data using removable devices, if yes you should have Anti-Virus software installed.

For a standalone PC, with does not use USB drives, you can consider not using Anti-virus. Such are generally specialized setups, such as setup for billing, book keeping in a SO-HO establishment. Lot of photo studios use imaging software and printers to process images and take printout.

Free Anti-Virus Vs Paid

This is a frequent dilemma of users if they can trust free antivirus. Often what I hear is that they have installed it but it does nothing. Again the choice is more of the anti-virus then that of whether it is free or not. I will recommend anti-virus which I have used and have personal experience to.

Microsoft Security Essentials: Free for Licensed copy of Windows, WGA check required. This is a good enough anti-virus for home use, on non-critical systems, where you may not lose business even if some virus get through , recommended use only for Home system setup.

Avast Anti-Virus for Home users: Again free for home users decent software recommended use for Home System Setup

AVG Anti-Virus – Again free and lives up to its name, A very good Antivirus, recommended use for Home system setups.

ESET Nod32 Antivirus – This is the best anti-virus solution I have used till date and I am using it regularly for few years now. Recommended use for all kind of computer setups. Nod32 is paid software. It does have a trial version.

My system runs slow after installing anti-virus.

Performance overheads will be there due to Anti-Virus Software, the question is trade-off of security vs speed, and up to some extent on how well the anti-virus handles the system. A Microsoft security essential is fast, so are Avast and AVG, the working of these softwares in the background somewhat noticeable. But the best I used till date has to be ESET Nod32. That the reason for recommending ESET Nod32.

So what to do, I cannot decide.

Summing up the discussion above,

1)  Depends on your system setup, you have to decide among tradeoff , security, cost, criticality of the system

2)  Once you have decided that, decide if you will shell out some money for Anti-Virus Subscription.

3)  If you want free, go with free else try some trial versions of paid soft-wares, I will recommend trying Eset, but do try Kaspersky, Bitdefender and others too.

Where do I get these Anti-Virus Google them and download their installers and install, simple as that. For free antivirus software, there is usually some registration involved, Avast sends you licence key for one year after you register on their website, Microsoft security essentials appears in optional windows update if you have no antivirus installed.

For paid once, I will suggest buying from online retailers. Keep a watch on the anti-virus software offers on Indian websites such as Flipkart, snapdeal, amazon.in there are sometimes very good deals with discount up to 80% on anti-virus subscriptions. You may also buy 3 PC or 5 PC license they are usually cheaper, the catch is that you have to find others to share the license with, as all license will begin and end simultaneously , so buying 3 pc license for year is not equivalent to 1 PC for 3 years.

I am buying and sharing 3 PC license for Eset with my colleagues for last 3 years, we all have our single laptops and we usually buy a three PC license from ESET and one of us activates it and all three get to use this license, and we split the cost between three of us. It cost usually cost around 300 – 350 which is like less than rupee one for expense on Anti-virus. We have used Kaspersky and Bitdefender in past too but ESET has been our choice for last 3 years. 

Buying a Steam Iron Press.

Philips GC2840 2200-Watt Nonstick Soleplate Steam Iron with Spray, Coating, Anti-Calc and Drip Stop

Since my old Steam Iron had some leakage issue and short-circuited. I was looking to buy a steam iron press. If you look around there are so many brands to choose from and so many different price range you may find a steam iron press for somewhere in between Rs 300  to Rs 11,700 .

Here is how I made my purchase. 

Brand : First decide on what brand you want, I decided to go for Philips as most of my house appliance is Philips and I trust quality of Philips home appliances. Other good brands with reasonable prices are Morphy Richards, Bajaj and Kenstar. I know there are numerous other brands like Jaipan, Orpat, Singer, Havells etc choose whatever you like but stick to the brand else narrowing on the choices becomes confusing. 

What to look for in the Steam iron press ?

1) Sole Plate is most important - choose premium types with plenty of steam roll.(thin noose ones are better)  

2) Wattage - higher the quicker, and for that constant steam roll.

3) Steam features - vertical steam shots (in case you want to steam clothes on the hanger, Steam burst for stubborn thick cloths like denim and certain curtains, continuous steam in (grams per minute)

4) Cord - For corded ones choose the one with at-least 2 meter wire for comfortable use and ball-socket swivel design.

5) Maintenance- how to clean, whether It is self cleaning

6) Weight of Steam Iron Press - too heavy and will be difficult to use and too light will be inefficient .

How to get best deal ?

Once you have decided on the brand head over to online sites for some rates. 

Indian sites I use in order of preference are (Flipkart, Snapdeal, Amazon, ShopClues, ebay) 

look on models and find the most decent steam iron you can afford by comparison of various features.

I narrowed my choice to Phillips  GC2820 or GC2840 (On budget of 2000 INR)

I choose Amazon to make the buy for ongoing offer

1) 15% off at checkout

2) Citibank offer of 10% cash back as Amazon Gift coupon.

The Steam Iron was billed to me for Rs 1872.55 and if i receive second offer too then effective price will be Rs 1685 /- though I have to make a purchase for the gift amount. for an steam iron with MRP of Rs-3495, I consider this to be a good buy. 

Deal Check for Phillips - GC2840

1) Sole plate - Steam Glide sole-plate is Philips premium sole-plate

2) Wattage - 2200 ( GC2820 about 100 odd rupees less was 2000 Watt otherwise identical product)

3) Steam - Vertical Steam preset, Continuous steam up to 32 g/min, Steam boost up to 100 g

4) 2m cord with swivel design

5) Calc clean slider to easily remove scale out of the iron

6) 1.2 kg weight 

Internet so many ways to hurt : Part-3

Part 3: Real world, Cyber world

You thought your cyber life will not impact your real life. Since we have touched on issues of how social networking sites have impact on your real life. Let see some more ways, how you may make a bad first impression.

Not able to find suitable life-partner?

Probably should check, if some portion of you online identity is objectionable, posting pictures of getting drunk in Goa, may get likes from friends but will surely keep the prospective in-laws away.

No landlord wants to give you his flat for rent?

Sharing pictures and videos of those wild-parties “#totally got wasted yesterday”, dirty flat pictures “#I haven’t cleaned the room in six month’s… LOL!” was not a good idea. Neither was trashing the place after weekend party and disturbing neighbors.

Getting soliciting calls on your mobile. Getting a lot of spam mails.

Then consider this leaving your phone number and email account at forums, at dubious website, for different Ponzi schemes is never a good idea.

Have to get rid of your mobile connection, because you ran up the bill too high by using 3G/4G?

Generally when internet packs are sold the details are obfuscated by service provider, it’s your job to clear up everything. Buying a 3G data plan with 1GB free limit and no bill shield is certainly affordable, but after free limit the charges are on per kilobyte basis, watching videos online after getting drunk may be fun but in the morning you will have to sell your kidneys to pay for that bill, losing the connection is a better option.

Got a Wi-Fi connection and got no idea how to secure it?

Be assured that things like somebody using your IP for illegal activities and stealing your internet, running up your internet bill, happens to somebody other.

General rule, “What can be used, can be misused and what can be misused can abused, and what can be abused shall certainly be abused.”

Got banned from a site? Friends or family not amused by your last comment online? What comment you ask?

Probably someone else was trolling using your account, you may not necessarily be hacked, you may have left a session logged in a public computer, or office common computer or some friends computer or a device, shared your password online, left you password written on your desk so on…

Lost a bet? Made a fool of yourself, because you took things on internet as facts?

This happens to every one of us, until we become jaded by internet and stop believing everything online. Wikipedia has come under fire for such thing as people can write/update things on Wikipedia you may use Wikipedia for knowledge but for facts you should verify before saying I read that on Wikipedia. Similarly on forums if you read advice, it may not be 100% correct. You have to check facts and do the research yourself.

This is all I can think of at this moment; do leave a comment if you remember some other ways internet can hurt. 

Thanks for reading.
