I have already back to KK, no root -- no gapps... Pls let me know when you find the solution. Thanks.

there's lolipop custom rom in russian forum,its original firmware with some tweaks and u can flash it using kitkat twrp, flash it together with supersu after flash that rom and then reboot,there' the only way to root s90 lollipop fr now as i know, but u will lose twrp and only stock recovery after that. i have tested it but went back to kitkat because cant use xposed in lollipop without custom recovery.

The simplest way, download qpst version of ROM (Vibe2.0 Android 4.4.4) and flash it by PC (QFIL utility).

Custom Recovery for Stock 4.3 (rooted)

Hey I was just wondering if it's possible to install a custom recovery while retaining the stock 4.3 firmware (rooted)?
I tried a couple of times but kept putting it into bootloops, so any direction is VERY welcome. Thanks much.

Not at this moment no, but it appears that a pre-rooted zip isn't far off.

This rooting method doesn't work on latest 4.4.4 for Z2

Is it the latest 4.4.4 for Z2? And is it pre rooted? Which means can I flash this on my locked Z2?

You will likely be waiting some time, because it's possible to downgrade and flash pre-rooted zip or to OTA certain FW's maintaining root, I don't see devs putting a lot of effort into finding an exploit. That said best hope is probably an exploit being found for Z3 which is transferable to Z2, but as I say you may be waiting some time.

Try to create a rooted update package from the update ftf: [4.4.4] Create ROOTED update package from stock FTF [LOCKED BOOTLOADER]
So I need to flash dual recovery to do that
How can I make a full stock backup just in case I need to use it for warranty?

You don't need, you can flash back an original ftf anytime or repair with Sony PC Companion. We are talking locked bootloadr, so until you don't unlock it, you have warranty.
But if you already have root on prev. firmware, you should install DualRecovery and boot into TWRP and you can backup your system there.

I just bought the phone and I really miss root hehe so if I don't unlock the bootloader I can change recovery and flash a stock root rom without losing warranty?

Yes, if you have older firmware on the phone, you can try the root options available and you can use recovery without unlocking th bootloader. If you have the latest, than you can possibly flash an older firmware to your phone and root that. But you need to read a bit, to understand everything correctly.

Thanks medwat! I used Towelroot to root the phone but only works on Jelly bean. As I understand the instructions be like:
1- upgrade to lollipop custom rom b322
2-Install twrp? (do i need root to install it?)
3-Root it from twrp? (How do i do that?)

You don't need to root Lollipop to install a custom ROM. In case you just want to root lollipop, download the super user zip file. Just google it. Launch TWRP and install the zip file. That's all.

I have been trying this method but doesn't seems to work, I already changed the name of the twrp img file but nothing :crying: any suggests?
You need to tell it where the file is located, the easiest way to do this is to put the TWRP file in a folder and then hold down the shift key and right click with your mouse inside the folder you put the file in. You should see an option to open command window here. Select this and try flashing TWRP again. It should work. Here is an explanation with pictures of what I was talking about with the open command window here http://michaelcrump.net/power-tip-for-windows-users-open-command-prompt-here/

I guess if you download the first ever android release for this phone from its official website and flash it via its stock recovery, you will be able to downgrade your phone to android Nougat.
Backup ur data before doing this. Coz it may delete your personal data.
NB: Do at your own risk. I have not done it. So cannot confirm if it works.
i can do it , tested

Is it still not possible for SM-T220 and SM-T225? Maybe there is a way to do and trick/bypass binary version via some kind of custom recovery? I'm kinda new to this topic would appreciate any informative responce! Thank You in advance!
very risky to try. for now bootloader was version 4 , Your BL must be v.1 if you want to downgrade firmware.
I know right, so there is absolutely no way to downgrade to android 11 with bootloader version 1 if I have bootloader version 2 or above and android 13?
