Thanks anyway! If anyone else using this GSI has the same prob and finds a solution please let me know
Or you can just try another GSI using FastbootD in your recovery which is a faster method. Yes, I bundled that custom recovery within the custom AP file -credit goes to tom.android.
1. Enter Fastboot through Stock Recovery
2. Enter "fastboot erase system" in command prompt
3. "fastboot flash system insertGSInameHere.img"
4. "fastboot -w"
5. Reboot to Recovery to do Factory Reset
6. Enjoy
because you used "Phh Treble Setting" to configured in Android 13 GSI , Do not set it , All bluetooth fixed errors were patched already.
Hi @nirogu325
Sorry for the noob question, but what is the procedure to flash this build onto a stock T220 , still with stock bl and firmware from samsung. I have the WA6 firmware on it, just don't understand how to flash the downloaded image you provided. thanks for all the help
Hey! Not OP but I flashed the GSI you mentioned a week ago on my WA6 T220. The GSI file linked goes into the AP slot, and everything else is stock (BL, CSC, etc). You need to have an unlocked boot loader. I also rooted my stock WA6 install before using ODIN to flash the GSI because the directions weren't clear, but I'm not sure if this was needed.

why is it depended upon Linux?Has anyone managed LineageOS for T220 WA6? I don't have linux
I will try to follow your guide. Sometimes with so much lyrics I get stressed, I'm more than reading only what is necessary.
Thank you!
Hello it's 3:50 AM here I am currently looking for help regarding the samsung galaxy tab a7 lite SM T220 running Android 11 I was wondering if you would be able to show me how to uninstall AND disable apps using ADB I'm new to this and managed to root the device a while ago I forgot how I did it but I would be grateful for your help
whenever i use lpunpack in wsl i always get command not found. ive went into the bin folder and stuff
lol I've figured it out, but now how do I update without losing data? And also can I install Magisk without losing data as well?
1.flash new update GSI image without wipe data ( Dirty flash).
2. flash new patched-magisk after install firmware , you can't do it without lost data same as you flash new GAPPS.
is there any way to fix offline charging on Pixel Experience? I don't wanna get stuck on the set warranty vbmeta thing
Can someone please compile a build for SM-T220, im getting an error in step 4 and im unable to figure it out.

never mind ! i just install fastbootd and a custom gsi from Tutorials ! THX A LOT @tom.android11Are there so many tutorials about SM-T22x here, from history till now from nothing (hard way) to very easy method why don't read and upgrade your skill from it. -
10Hi everyone, this is a short guide on how to flash a GSI on the A7 Lite (without TWRP).
Its a nice little tablet for the price but it doesn't have a very powerful SOC and for me the One UI is barely usable on this device. The launcher and the whole system UI feel extremely laggy, but apps generally run fine.
I tried phhusson's custom Android 12 GSI and the device was almost resurrected. Much much less UI lag and the battery life is the same as stock ROM. The only thing i found not working is MTP but i don't need it.
Since i saw a couple users here asking about GSIs i decided to make a very simple guide.
As always do this at your own risk. You may brick your device. You will void your warranty.
Follow the guide only if you know what your are doing. Read each step carefully and avoid copy pasting stuff randomly.
I won't go deep into details as i believe you should have some basic knowledge if you decide to do this.
The procedure sould work for both T220 and T225 (i tested it on a T220).
I did this on Windows using WSL for some of the steps.

Hello, although I'm working in Linux (VM too)...

- lpunpack and lpmake
- tar-md5-script-tool
Use the attached tar-md5-script-tool.zip
Steps
1. Extract official ROM files (BL, AP, CP, CSC)
2. Extract AP .tar.md5
3. Decompress the extracted super.img.lz4
Code:lz4 -d super.img.lz4 super.img
4. Convert the sparse super.img
Code:simg2img super.img super.ext4.img
5. Unpack super.ext4.img
Code:lpunpack super.ext4.img
I got 4 partitions in my image (should be the same for all T220/T225 ROMs):
- odm.img
- product.img
- system.img
- vendor.img
6. Replace system.img with your GSI (rename it to system.img)
7. Get the size of all partitions and the size of the original super.ext4.img (not the sparse super.img)
Code:stat -c '%n %s' IMG_FILE.img
8. Repack super.img
Code:lpmake --metadata-size 65536 \ --super-name super \ --metadata-slots 2 \ --device super:ORIGINAL_SUPER_IMG_SIZE \ --group main:SUM_OF_ALL_PARTITIONS_SIZES \ --partition odm:readonly:ODM_PARTITION_SIZE:main \ --image odm=./odm.img \ --partition product:readonly:PRODUCT_PARTITION_SIZE:main \ --image product=./product.img \ --partition system:readonly:SYSTEM_PARTITION_SIZE:main \ --image system=./system.img \ --partition vendor:readonly:VENDOR_PARTITION_SIZE:main \ --image vendor=./vendor.img \ --sparse \ --output ./super_new.img
Replace ORIGINAL_SUPER_IMG_SIZE, SUM_OF_ALL_PARTITIONS_SIZES, ODM_PARTITION_SIZE, PRODUCT_PARTITION_SIZE, SYSTEM_PARTITION_SIZE, VENDOR_PARTITION_SIZE with the values you obtained in step 7.
Read lpmake docs for a more detailed expalation of the args used above:
9. Compress the repacked super_new.img
Code:lz4 -B6 --content-size super_new.img super_new.img.lz4
10. Compress the clean vmbeta.img
Code:lz4 -B6 --content-size vbmeta.img vbmeta.img.lz4
11. Extract tar-md5-script-tool.zip
12. Put all the *.img.lz4 files extracted from AP .tar.gz in tar-md5-script-tool dir
13. Replace super.img.lz4 and vbmeta.img.lz4 in tar-md5-script-tool dir with your repacked and compressed super_new.img.lz4 (rename it to super.img.lz4) and the clean compressed vbmeta.img.lz4
14. Run batch.bat in tar-md5-script-tool dir
You will find the new AP .tar.md5 in the temp-folder subdir
15. Flash your custom AP .tar.md5 with Odin along with BL, CP, CSC from original ROM
16. Reboot into recovery and do a factory reset
17. Done2

No, your base is not the problem. That particular version of A12 CherishOS uses PHH v415 which has issues booting for our devices. Only PHH v414 or v416 GSIs like this one boot for us (it works for VJ2 firmware, tested it myself). Sadly I don't see any other developer releasing an A12 v416 based GSI like the one I linked to so yes, that's what we have for now until the newer A13 GSIs pick up the v416 patches hopefully.
