Hello, I have a problem, do all the steps but when I click on Restore in mobile, not the message that should be in the Windows console, either restarts or anything ...
Also when I click on Restore (the backup is loaded BootMe) takes not even half a second in "restored"
PS: I have debug mode and third applications on.
Guide I used: http://forum.xda-developers.com/showthread.php?t=1886460
Other: That the 2nd time I root my Xperia S. The first time worked, but now no.
Someone help me?
You may have an updated firmware that blocks the exploit. If you do you'll need to flash a rootable ftf then root. Search the Xperia S forum for the files

don't root, unlock the boot loader first then flash a rooted rom, much much easier

If you don't want to lose DRM keys and Warranty, first flash a rootable .ftf file using Flashtool. You can find link in your forum. DO NOT unlock your bootloader. It voids your warranty. If you don't care, unlock it. And Use the search function before starting a new thread.

Hi.
I have one sony xperia u with android 2.3.7 and i want to simply root this phone and if this happened without loosing any data.
I have already try these steps
http://www.youtube.com/watch?v=x65ua5x4sMc
but at step 12 it seems like the mobile doesn't response at all and i don't know how to install the step 4(android sdk software)
And i try even that without any results.
I believe it need to unlock the bootloader so i can proceed with root but because i can't install the android sdk software the xperia u doesn't communicate with my pc.
before you go in the developers only forum find your device in the search box..if you cant do that go here http://forum.xda-developers.com/forumdisplay.php?f=1515
for rooting your XU try this http://forum.xda-developers.com/showthread.php?t=1886460
and you dont need to unlock your bootloader to root a sony device

go ahead and update your device..no harm in that..use bin4ry's rooting method after that..try using v13 first though before using the latest..
Hi i own several android devices all rooted and running well. Now i got this tablet from satan and i need help.
The device came with android 4.0.1 and someone did a unlock to the bootloader (can't update OTA). I did the nvflash guide and i was also able to root it. Now i just want to upgrade the device. I intalled a recovery via fastboot.. it wont boot to it. Tried to manually install a official update got a 'Failed to process command flash:system error (0xa)'. Seems like everything i try to do all i get is a dead end.
Please help me to upgrade this tablet to JB.. or any other custom rom. I would be happy if i could just boot to recovery.. lol
Thanks
by the way my other devices are nexus 7, galaxy i9300, xperia arc S (so i have some experience in rooting and upgrading, xperia was terrible also)

Hi!
I rooted my Asus Iconia A1-810 with the RV21RC02_WW_GEN1 files according to the thread:[ToolKit] Acer Iconia v0.8.1 ***New: Supporting A3-A10 / New: Pull system.img.gz*** http://forum.xda-developers.com/showthread.php?t=2240029
This was done several month ago...
But some of my apps need me to update to newer firmware according to the app-developers.
Unfortunately I don't know the best way to upgrade a already rooted device ?? Whats the easiest way ?
Do I need to first unroot the device and do firmware upgrade.... or is it possible to upgrade directly ?
Is there some good howto out there ?
Many Thanks
Marcus
Someone here ought to have information that might help me...please!
Hos do I update the firmware on a rooted device ? In my case asus a1-810.. ?
Thanks
Marcus
*argh* .... This is killing me...
I've read everything in the Acer Iconia Toolkit thread...... but because I have less then 10 post I'm not authorized to ask any questions in that thread ?????
So I'll have to ask here until someone answers or I reach 10 posts...
Anyhow...
My system.img.gz that is currently loaded and rooted is RV21RC02_WW_GEN1.
But there is no one offering a Stock / unrooted image for that !?!?
I've tried to to stock firmware upgrade through menu with the tablet rooted - NOT WORKING
I've tried uninstalling the SuperSU with the unroot-option in SuperSU menu. -NOT WORKING
I've was about to try the unroot option in the toolkit from windows.... but it says i need a stock image in the system_image folder ? -Dont have stock image RV21RC02_WW_GEN1
I've read that it's not a good idea to try and upgrade with another image (not RV21RC02_WW_GEN1), Then i'll brick the tablet....
But what should I do ???
/Marcus
Same problem
I have exactly the same problem with my rooted Acer A1-810.
I used the toolkit to root my pad (RV21RC02_WW_GEN) a couple of months ago. And now I would like to find the original stock rom so I could unroot my device and update it. I have tested the same things that you tested but it didn't help.
I read the guide (http://forum.xda-developers.com/showthread.php?t=2301762), and it says "you may have MF3, which causes problems" , but does not tell you how to check.
I googled my problem and it told me the build number (ktu84p.i337ucufnj4) has that information.
As per the title, I'm just looking to root an ATT Galaxy S4 and install CyanogenMod as simply as possible. I've rooted a copy of the same phone before, so I don't need step by step instructions, just the proper root method and any conflictions with my phone.
Thank you for any assistance!
I promise I've been researching this for days!
I understand now my firmware is NJ4, and found this guide http://forum.xda-developers.com/gal...to-root-i337ucufnj4-4-4-4-11-13-2014-t2939553
I'm confused on how to install Cyanogenmod now however. The only supported device/guide that matches mine I can find is here: http://wiki.cyanogenmod.org/w/Install_CM_for_jflteatt
The disclaimers says it will only work on I337UCUAMDB or I337UCUAMDL though. It also says I should use CWM recovery, but another root guide for my device says we can only use safestrap...I'm seriously trying to understand here, can someone give me a hand?

Hi,
The reason you cannot find anything is because it is currently impossible to install CM on NJ4. NJ4 has a locked bootloader and prevents all but stock based ROMs via Safestrap for installation.
