Hi all
I have a Xperia Z2 SGP521. I downgraded to version 17.1.A.2.69
I did that with Flashtool. Afterwards i rooted with Towelroot and installed SUPERSU.
Now i have full root.
I get the message that there is an OTA update. Can i do that without loosing ROOT ?????
Can i flash the stock Lollipop ROM without loosing ROOT (from Experifirm) ?
Does someone have a firmware package (FTF) prerooted wich i can flash with flashtool. I dont want to flash recovery....because i lost all my data triing that
If you find this Q to be obsolete because it is asked a million times......neglect it.
There is so mucg info on this but not with the ezact firmwares i use or wanna use and i have been told this device can brick easy. So this Q is to be shure !!!
THNX in advance forhelping comments.

hey,
i flashed cyanogenmod on my ray.. but after all u flashed the stock rom again from this forum (ftf via flashtool).
the thing is that SE companion software says (if i want to update /repair my firmware) that the firmware is modified and it wonmt update it. now my question: do i now always have to flash the new roms (for example when ICS will come) or is there a method to get back to the real stock rom so that SE companion will update/repair the firmware?
im on android 2.3.4. (http://forum.xda-developers.com/showthread.php?t=1316070)
its rooted and the kernel is still the one from the cyanogenmod (i think- well, i didnt flash any new kernels after cyanogenmod..just flashed the rom)
bootloader is unlocked
hope you can help me..thx
yes after unlocking bootloader you always have to install stock firmwares via flash tool
use wotan server , it is a great way to install stock rom
hmm okay thanks! .. btw is there a way to lock the bootloader again so i can install the firmware with SE again?
thanks for the tip!
Hi. I have problem with my SE becouse i update my phone to v62. I cant root becouse is not possible on this soft version. I cant unlock bootloader cuz bootAllowed=no . I can install fresh ROM via flashtool? When no what i must do? Please help. (Sorry for my english).
You can only install a fresh stock .58 rom via flashtool or wotanserver then root it then update it .62 (now with root) then install clockworkmod recovery. You then have to pay to unlock your bootloader. You can't install custom full roms and custom kernels w/out unlocking bootloader.

Hello, I used this thread as a guideline to root my phone.
http://forum.xda-developers.com/showthread.php?t=1568792
Basically I had to downgrade the firmware to .42 with the ftf file on that thread flashing it with flashtool (link for flashtool also provided in that thread), use zergrush to gain root access and install both busybox and Superuser.apk (it's fixed in .62 so you can no longer gain root with zergrush) and then update the phone using OTA back to .62. Updating to .62 does not make you lose root access. All you need should be in that thread.
If you want to unlock the bootloader to install custom roms and kernel I can't point you to a method that works for sure since I have no intention of unlocking mine as I am quite happy with the stock rom but there are plenty of threads on this forum about it.
Hope this helps!

Simply reflash your phone again by a stock official ROM. You can also use "Unlock Root" , you can get it here :

HI, I wanted to root an Xperia Nei mt15i, i found an article with a step by step guide ,which said downgrade the firmware to 2.3.2 then gingerbreak etc etc, and well now the phone says that the battery is empty, and i cant install a custom firmware becouse i cant unlock the bootloader, so i cant get in fastboot mode, anyone can help please?
To root you dont need unlocked bootloader.
follow this guide
http://talk.sonymobile.com/thread/35239
Flash .42 firmware NOT .62
then root
http://forum.xda-developers.com/showthread.php?t=1312859
After that use Over the air update to have latest .62 firmware or if you dont care stay with .42
You will be rooted with locked bootloader
(BE CAREFUL YOU NEED XPERIA NEO FIRMWARE NOT XPERIA NEO V!!!)

Thanks, and will this fix the battery issue?? Ive downloaded the 4.0.2.A.0.42 firmware from the site you wrote, but in flashtool it seems "empty" no firmware content, and nothing in the other columns...:S
Where did you read that you need to downgrade to 2.3.2??
Now you killed your battery gauge and it's unrecoverable hardware failure. Only permanent fix is replace in service shop.
There are some custom kernels which have 0% fix, there is even fix for locked BL's, for more information read this thread: http://forum.xda-developers.com/showthread.php?t=1312398
If your phone is under warranty, you can try giving it for repair under warranty.

Hello Sir .
Thank you for the reply.
Regarding my last question which is question C the "yes " means that if i keep upgrading the custome ROMS which have some changes of STOCK ROM in same enviornment i dont need to root again the device am i right?.
What can i conclude that any ORIGAl ROM(STOCK ROM) needs to do root after upgrads.
My last and big question is :
d) Why this behaviour? why cannot we do root for ever and ever? so it means that if i bye a device which comes locked from local operator it will never like as the one that comes unlocked originaly.???? there will be always a difference between device which is rooted from factory and which is rooted by use....why this differences?????
