I found this thgread when looking for a TWRP for a Exynos 850 based A13 (The 4G version). When I try to compare the A12 and the A13 online it shows tha A12 having mediatek chipset. Has the European A13 been sold as A12s in other regions? Also, how big a challenge will I have trying to use this twrp for the A13?

BTW gsmarena shows the S12 Exynos version as 'Nacho'.
[Samsung Galaxy A12] physwizz:
A125 is mtk

A127 is exynos 850

M135 is Exynos 850

M137 is mtk
[Samsung Galaxy A12] T_I:
Interesting, now I'm getting more curious how much the A127 and M135 differ and if the differences are small enough for TWRP to work..
[Samsung Galaxy A12] physwizz:
M135 twrp should be easy to make.

I requested a source code from Samsung but it had a bug.

If you send me m135 recovery.img and boot.img I'll see what I can do

Can this TWRP be installed on Android 12 U7 binary? (A127FXXU7BVI6) Another question, if I ever able to install TWRP, is there a chance that I can install the GSI LineageOS 18.X on my phone? I really like to use LineageOS because of the volume rocker media skip feature, I wouldn't mind the downgrade. Thank you very much for any answers

Thank you very much!
[Samsung Galaxy A12] juliano-oh!:
The download link is not working, do you have any copy of the recovery.img for U5? Thanks again!
[Samsung Galaxy A12] juliano-oh!:
Thank you! I found it on your awesome Telegram channel while researching. Say, is there a chance that you can port TWRP version 3.3.X for U7? The reason for this is because it has a feature that resizes the system partition, which I need to install GApps on a GSI. Or do you have a solution for installing GApps on GSIs? /system/ partition space seems to be lacking. I appreciate any help. Thank you very much for your efforts in keeping the A127F development scene alive, you're the man. :D
[Samsung Galaxy A12] physwizz:
Thanks.

You can download a GSI with gapps included

[Xiaomi Mi A2 / 6X Questions & Answers] worcester_lad:
I charged my Mi A2 overnight and woke this morning to find that it won't boot past the Mi A2 splash screen; it shows the splash screen for a few of seconds and then dies. I read advice to hold down power and 'up' keys, this just resulted in the same. I tried power and 'down' key and that got me as far as the Fast Boot splash screen, but no further (phone just continued to display that splash screen). I've tried taking the SIM out and turning it on - no change. I tried opening it up and disconnecting the battery for 3 minutes - no change. I'd be very grateful if anyone could suggest a fix. I know this is hugely unhelpful, but I can't remember what I did to the phone in terms of unlocking the bootloader and/or rooting, but I have a feeling I left it stock (I've owned the phone for a couple of years and haven't changed anything material since initial setup).
[Xiaomi Mi A2 / 6X Questions & Answers] Martinocom:
Disclaimer: you need adb tools to execute following command. You can find info where your wish about it.

Try to make it on FastBoot mode, then attach to PC and execute

fastboot reboot

If it brings you again to flashing screen, again, bring the phone in fastboot mode. Then try to change active slot.

fastboot --set-active=a

If not working with a, try with b. After setting it, launch the command to reboot again.

What recovery do you have? Pressing up + power when turning on where brings you?
[Xiaomi Mi A2 / 6X Questions & Answers] worcester_lad:
Thank you very much for your help.

Executing fastboot reboot via adb just brought me back to the Android One splash screen for a few seconds before the screen went black.

Changing the active slot to both A and B gave me the following error message:

FAILED (remote: 'Slot Change is not allowed in Lock State')

Pressing up + power when turning on just brought me to the Android One splash screen for a few seconds before the screen went black. I held those two buttons down for several minutes and the same thing kept happening: splash screen followed by black, repeatedly.

Is there anything else I can try?
[Xiaomi Mi A2 / 6X Questions & Answers] Martinocom:
You can try fastboot oem unlock or

fastboot flashing unlock to try to fix the "Locked State".

If I'm not wrong it erases your data! Before doing it please be sure and wait for some more time: maybe there is another solution for it!!!​

Main reason I'm making you this steps is that I think your phone applied some kind of system update that break something. Thanks to A/B partition maybe you can have a working system on the "not corrupted" one, so I'm trying to get you into it (either A or B)

Remember that doing this commands sometimes make the situation worse, or format your data, so please read if there are any side effects.

If nothing will work you can try to wait for someone more expert than me. Maybe you have a chance to recover from this state.

Another thing: turn on the phone (normally) without holding it in charge. I had a bug that won't let me pass the splash screen if phone was charging.

If really nothing works, try to find a tutorial on how to flash a ROM via TWRP, there are plenty of them. You will probably loose your data.
[Xiaomi Mi A2 / 6X Questions & Answers] worcester_lad:
Thank you.

If anyone reading knows of a way to get my phone to boot without losing my data I'd be very grateful for your help.

This has already been posted in the hacking and development forum, but for those folks who do not frequent that forum, I am posting it here.

This cab enables Rogers Name Display (while on Rogers/Fido) when using a non-Rogers ROM. I have tested it in Shadow 2.1 CE, TESS 2.5, and OpalR2. This cab simply replaces the rilgsm.dll with the one from the Official Rogers 6.0 ROM and enables the feature in the registry.

So far it seems that it can be safely removed if you decide you don't want it. It has only been tested on the Touch Enhanced (ELFin). It may or may not work on the original Touch (ELF).

Note: this has only had limited testing, so use at your own risk.

Great, was following the other thread earlier, didn't realize we had a solution. Thank you for letting everyone else know.
