I did this exact thing. Tried using the stock Tmobile rom in order to unlock for free. I should have just bought a stupid unlock code. I am stuck with this Tmobile stock rom that freezes at "KERNEL IS NOT SEANDROID ENFORCING SET WARRANTY BIT: KERNEL" on the boot img screen and then finally boots normally

[Galaxy S II Q&A, Help & Troubleshooting] MistahBungle:
You need to try some kernels out to find one that works for you (Previous poster meant mods will be closing this thread soon, because I reported it).
[Galaxy S II Q&A, Help & Troubleshooting] zeko_1992:
i want but i can't may be kernel could damage my device so i asked here to know what is the best
[Galaxy S II Q&A, Help & Troubleshooting] MistahBungle:
As long as you use a kernel for the I9100, it won't 'damage your device'. Sure, the phone can get hot if you do certain things (dopey things, like playing CPU/GPU intensive games while on charge) while running certain kernels, but that's a trial & error thing. If you're on XDA in the first place, it's assumed you like messing with your phone & trying stuff out.

So...I think you have some reading over in the Android Development & Original Android Development sections & then some flashing to do.

Edit - One tip I will give you though; you can't have 'battery life and make GPU & CPU work excellent for application and games like asphalt 8 or need for speed most wanted'. It's a phone. You can have one or the other - great battery life, or great performance. You can't have both. Think about it, if you want to run games like that at the highest quality with no lag, you're going to chew through battery like there's no tomorrow. There's nothing you can do about that.

Hi.

I have rooted SGS2 and I'll like to install stock 4.1.2 uk stock firmware.Can i install than firmware if I'm in Canada?

Any step by step info would help.

I have flashed my device dozens of times but never did go back to stock.

Thank you very much
[8125, K-JAM, P4300, MDA Vario General] rookery:
I just think about it, how many time can a flash disk be read and write? is it limited say 50000 times? what will happan if the flash dead, the phone also dead !!! am I correct ?
[8125, K-JAM, P4300, MDA Vario General] 3waygeek:
You're right in that flash does have a limited number of write cycles; that limit, as I understand it, is per cell, and not per chip.

There are extra cells in the flash to accommodate failures in individual cells, sort of like spare sectors on an IDE drive. Control circuitry in the flash handles the mapping between memory address and flash cells; it also has a load balancing algorithm to ensure that all cells get roughly the same wear.

When HTC (or anyone else) designs a flash-based device, they take this kind of stuff into account, and specify parts with high enough write cycle limits to last well beyond the expected useful life of the device.
[8125, K-JAM, P4300, MDA Vario General] rookery:
Thanks,

so, we are worry free now????? the flash won't die before I buy another phone say three years later ?

but i jsut found those

[8125, K-JAM, P4300, MDA Vario General] far182:
They have intellegence on the flash that disributes the writing of information accross the flash evenly. This reduces the changes of there being a problem.

Hi All,

I have a HTC ONE SILVER and I love it.

The only thing I dont like about it is that the linkedin contacts, which are linked to my hotmail/google contacts in people hub get delinked automatically after few days (maybe after manually syncing accounts in settings menu).

Then I have to re-link them (the numbers go in 200+ contacts) to the existing linked accounts through contacts link suggestions or manually linking them.

Please advise why this keeps on happening.

Is there any solution?

Hi!!

Just got your Xperia Z Ultra and start looking on how to root, unlock your bootloader and do everything you can for start playing with your phone with a maximum of security? You are at the good place!!​

First of all, install PC Companion, you just need to plug your phone on the PC and follow instructions on your phone and PC.

To make things clear, I didn't do any of those tools and link the threads where they come from, so if you want to thanks devs do it there. I tried all of them without any problem and I do this thread for help people who know nothing about Sony Android devices or simply want to find everything in one place. They are fully working, so if things go wrong while following explanations this is bad luck, you did something wrong and/or forgot to do something. Neither I nor the Devs can be kept responsible for what you are doing on your device.

[B]How to enter Flashmod and Fastboot mod [/B]

Root and TA Backup

Mod edit - VRoot links and install guide removed

until such time as the validity of this software can be determined due to some security concerns regarding this application.

Youtube tutorial made by hamdogg

Thanks a lot hamdogg

First tool you need to know when you own a Sony Android device is Flashtool. I invite every owner wishing to root, unlock or mess with your phone to install this program and install Flashtoo-drivers.exe (directory: C:\Flashtool\Drivers\). This tool is a jewel, you can flash any factory firmware, unlock your bootloader and cherry on the cake, make a TA backup, that will backup all your TA partitions including locked bootloader with DRM keys. Keys those are necessary to enable X-Reality and bravia engine.

But to be able to do a TA backup you need first to root your Z Ultra.

- First of all you need to enable USB debugging, you will find it on /Settings/Developer options. For enable Developer options you need to go on /Settings/About phone/ and tap 8 times on Build number.

Mod edit - VRoot links and install guide removed

until such time as the validity of this software can be determined due to some security concerns regarding this application.

- OK, now SuperSu closed by itself and disappeared, no stress it's normal, just restart your phone.

- After full reboot, open supersu again, and it won't ask you for update binary anymore. Just close it.

- Download Titanium Backup Root and open it.

- Just be patient, promt for root access can take time, but it'll come.

Enjoy!!

I just updated from .526 to .532 and done this process and it was successful at the first try. If it doesn't work just try again. It work on any firmware version and country

All is thanks to [MENTION=5434691]nickylou88[/MENTION] for this process.

And if you need more support you can look at this thread you have all information you need inside. The OP introduce another program, but VRoot is the less complicate to use and work as well.

Now you can make a TA backup following the instructions on this post.

Ok, now your phone is rooted, but more important you made a backup of your TA partition. It is important because if you soft brick your phone or wish to restore your bootloader to locked state if you unlocked it now you can.

I am not doing a TA backup tuto as the one on the original thread is more than complet

Here there is the other program that allow you to make a TA backup.

hamdogg provide us a really good Youtube tuto.

[B]Unlock bootloader and Install Recovery[/B]

Sony offer us a way to unlock our boot loader here but we have Flashtool, so why not use it instead? Easy and fast.

-Just click on “BLU” icon next to the flash icon

-Remember how to enter flashmod.

-Remember how to enter fastboot mod

-Click on Get Unlock Code then follow instructions on Sony website

-Enter the Code Sony sent on your email and let the program do.

When done boot your device you are unlocked.

Now it is time to flash Recovery. For do so you need to have adb and fastboot on your PC, all the information you need for install it and more can be find Here.

Another Youtube tuto from hamdogg

[YOUTUBE]9E7c7AfaQbo[/YOUTUBE]

To flash recovery you need to put advanced stock kernel v5.img to “C:\SDK ANdroid\sdk\platform-tools\” then type :

fastboot flash boot C:\SDK ANdroid\sdk\platform-tools\advanced stock kernel v5.img

Reboot your phone to system a first time then turn it off.

To enter CMW:

-Turn on your phone as usually

-On Sony boot Screen look when the led turn purple push volume up

-Enjoy CMW

To enter TWRP:

-Turn on your phone as usually

-On Sony boot screen look when the led turn purple push volume down

-Enjoy TWRP

[B] Flash or update a firmware from another country [/B]

While looking on the forum it is possible for you to find someone posting the latest firmware, but when you plug your phone on your PC and look for update with PC Companion it tell you have the latest firmware. It simply because the firmware came out first on another country, you can simply wait for it to come in your country. If you don't want to wait you have 2 possibilities.

- Download the .ftf and flash it via Flashtool

Follow step by step this post

- Modify your CDA code on your build.prop but need to be rooted

Open build.prop with any explorer with root permission (I use root explorer) and modify the following values with the values you need:

Reboot your phone then plug it to your PC and update with PC Companion.

YEs, you do not lose it. Nobody using this tool loosed it. It doesn't touch at your TA partitions. After rooting if you are really that much concerned about your DRM keys you can make a TA backup. SuperSU is an application so it doesn't require anything from the bootloader.

it's been a long time since coming into this part of the forum..

i've been rather happy being on .257 LTE version, rooted and what not with stock rom..

i've come to a point now that i have to upgrade to 4.3 or newer due to the notifications listener service introduced in KitKat. It's been a LONG time since i've played around with rooting and flashing, so, i have some questions for the gurus here..

- my bootloader is locked, can i upgrade from 257 to 14.2.A.136 (that's what's showing on my notification bar) and keep root?

- if not, what do i have to do to upgrade, and also gain/keep root, and am i able to keep bootloader locked?

- what is togari? the carbon rom looks interesting and i may want to try it some day
[Sony Xperia Z Ultra] LordManhattan:
- Why don't you update to 757 (Kitkat)?

- There are plenty of threads about rooting.

- Togari is the code dame of the Ultra.
