When you flash with odin you have to boot twrp with combination of buttons, if you don't tablet will reflash stock, a suggestion to not go crazy would be to flash with flashify and after flash select reboot to recovery, about the build of the os it should be Android 11 2021, June I believe, I don't remember exactly, others will suggest you the right build

Hi Sr. do you have a11 kernel sources tarball somewhere ? the a12 one does not boot for a11 because the modules in /vendor/lib/modules don't match i have compiled a12 sources from your github all works on a gsi with a12 vendor and other stuff as base

Thank you

Skorpion96​

for building this TWRP.

All of the pages for this build state that MAGISK 24 - is the only one that works when installing.

may i ask, ( using a SM-T220 ) after installing a patched boot.tar, and TWRP, is it possible to update MAGISK from this TWRP ? ( haven't seen this asked yet. )

is their any hope this gets added to the OFFCIAL TWRP page for recoveries ?

Hey guys,

Device : SM-T220 Wifi
i think i ****ed up a bit. I tried to root my device on A12 and ****ed up the boot.img step. Well i recoverd it with the full Downloaded Stock AP File (4,42GB) EU Version.

The thing now is i just got 4GB of Storage (Should be 32GB) in the System. As im on A12 now i cant use TWRP to resize the partition. Any progress on TWRP for A12?

Btw. i got extracted working recovery.img so i could play around with different test versions of TWRP if needed.

Or can i flash complete A11 Image and use TWRP there?

Go to stock recovery and do a wipe data/factory reset. In fact, format data is being made and the device writes about it ... The memory will be restored in full :)

if iuse the stock_defconfig the compilation stops telling me that some dirs are missing from drivers/misc/mediatek and they are present in A12 kernel sources but compilation still fails after add them so my recomendation is recompile TWRP but with A12 kernel sources instead of the a11 ones maybe this way we can get touch on sm-t220

Check / Compare The Lines That Have + an - the plus ones are the stuff missing from the kernel config inside the tarball the CONFIG_CUSTOM_KERNEL_LCM option is what concern to touch , the kernel does compiles fine with the original config but on real android when boots crash and reboots on TWRP stays for some reason but without touch and maybe other functions

    Yes that happens because Samsung didn't include touch drivers, so it's a matter of be lucky. If we can boot A13 kernel twrp will be released hopefully with touch support

Please * do some research if you have any concerns about features included in this Recovery * before flashing it!

    Remember this is in early development (alpha)
    1. Not Working:
    2. > Adb Sideloading
    3. > Vibration (minor issue)
    4. > Other Problems: Sometimes when you boot recovery touch not works and only solution is to re-flash TWRP again from Odin, this is kernel issue, we need custom kernel. I found out that in that case you can reboot with usb otg and mouse connected and twrp could start working on next reboot.

    1. Install Instructions
    2. Flash TWRP from Odin on AP Slot & Hold Volume Up + Power while flashing until TWRP appears.
    3. Go to Advanced > Terminal and type "multidisabler" (without quotes", then data wipe.
    4. Now reboot into system, after completing first setup of the device reboot into TWRP again to see if you can see the contents of your Internal Storage, you should, if yes you have successfully disabled Samsung encryption of internal storage.
