Hi,
I have a rooted SGP521 (4G) purchased in Australia. It is unlocked and rooted 4.4.2 (17.1.1.A.0.402).
1. Do I need to flash dual boot recovery BEFORE upgrading?
2. To upgrade to LP do I need to flash 690 first and then 726?
3. If need to flash 690 first, which pre-rooted file is most suited?

Thanks a bunch!
1. yes
2. no (you flash the whole firmware over the currently existing one)
3. I'm not familiar with SGP521

I have planned to flash a Pre-rooted image but there is no Pre-rooted image available for my country firmware i am using Indian Generic .75 is it normal to flash other country pre rooted firmware of the same version or it will kill my phone.
Flash Advanced Stock Kernel and you'll have root.
wat is Advanced Stock Kernel
Look in the dev section.
The other (but more difficult) solution, create your own prerooted image using this instruction

Hey,
I'm currently running my Razr on this version (still Gingerbread 2.3.6). Until recently, I avoided to flash any custom ROMs on my RAZR, because I wasn't sure, if that might work with this obviously branded Vodafone firmware.
My questions are now:
1. is this a branded version at all?
2. is it possible to debrand it?
3. if not, is it possible to use any of the ROMs around arbitrarily?
4. is it possible to unroot and flash back to normal systemconditions in case there is a technical problem?
Thanks for your help guys.
I recently got a network unlocked ST18a and upgraded through the phone's Wi-Fi to build 4.0.1.A.0.283 (Gingerbread 2.3.4 branded by Canada's Telus Mobility). It's now on the highest build available via OTA upgrade (I didn't want to install Sony's software on my laptop). I successfully unlocked the bootloader using SE Bootloader Unlocking v1.6. However, upon reading the instructions for installing CWM, they mention different starting build version as a requirement for installation, so now I'm uncertain what to do and don't want to guess, knowing the possibility of bricking.
Should I:
1. Proceed to install CWM without concern of the difference in my current build?
2. Relock the bootloader, upgrade to 4.0.4 ICS using Sony's software on my laptop (I'm assuming that's an option) and then proceed?
2B. If I go this route, what is the proper method to relock the bootloader? I've seen instructions to flash with the .ftf file in Xperia_Relock_Bootloader.zip but I'd like some reassurance here since I've read posts where people have bricked their phones attempting a bootloader relock.
Do not need to Relock the bootloader if you just hava to flash the .tft

hi! almost every kernel has cwm/twrp recovery installed so you just have to flash kernel that is compatible with your rom and you will have it
This thread was moved from the development section to this one, please remember, all the questions belongs to they own section and not development.
Thanks

You just have to install any custom kernel for gingerbread, I guess all kernels in dev forum have cwm preinstalled

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.

Can be closed !!!!!!!
As per the thread title, I have a new Rogers Sgp621 on 23.0.1.A.30 (4.4.4) As it's Rogers device, the bootloader is not unlockable.
I understand the lollipop method - flash z3 system, root, etc, as per guides here. My question is, is all that necessary or is this stock KK firmware vulnerable to towelroot or other simple methods, and if so would it be easier to root this firmware, install recovery, then flash a prescription rooted lollipop? Or should I just upgrade normally and follow the instructions for rooting the latest firmware?
