Sorry to disturb you again which Firmware you compiled for me. Thanks ( Firmware version)
Here you go, https://www.filehosting.org/file/details/8098279/GSI-12_SM-T225_THL_T225XXU1AVB2.zipThank you very much ...
If you don't like the default setting for taskbar height, try this magisk mod: https://github.com/Coxxs/hide-tablet-taskbar/releases/. Use the ones for PE.
Very good GSIs ,Thank to @xpdragon
Support things: Telephony , SD CARD(ex-fat format), Face unlock, Bluetooth (Sony headphones wh-1000xm4 , Samsung Buds 2) Camera .(with low quality)..etc.,
Love it.
**Note: for Samsung wireless headphone don't allowed unlocked os to install "Galaxy Wearable App" then please updated your headphone firmware before.

A bit clearer information for those building GSI trying to understand what some letters mean (source):
Some information you should know about knowing what type of gsi it is
<ARCH>_xyZ
<ARCH> can either be arm, a64 (arm32_binder64) or arm64
x can either be a or b
y can either be v, o, g or f
Z can be N or S
b = a/b
a = a-only
g = gapps
o = gapps-go
v = vanilla (no gapps included)
f = floss (free & open source apps instead gapps)
N = no superuser
S = superuser included
so in most common example "arm64_avN" is ARM64 A-only vanilla with no superuser
<ARCH>_xyZ
<ARCH> can either be arm, a64 (arm32_binder64) or arm64
x can either be a or b
y can either be v, o, g or f
Z can be N or S
b = a/b
a = a-only
g = gapps
o = gapps-go
v = vanilla (no gapps included)
f = floss (free & open source apps instead gapps)
N = no superuser
S = superuser included
so in most common example "arm64_avN" is ARM64 A-only vanilla with no superuser

Stuck on Set warranty bit: vbmeta
Hello guys, Recently I installed an Android 12 GSI on my tab A7 Lite because One UI on the tablet is barely usable and always lagging. But when I try to charge the tablet when the battery's empty, the tablet stucks at "Set Warranty Bit: vbmeta"...

6Hi 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)...
forum.xda-developers.com
- 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
Happy testing
GSI: lineage-19.1-20220613-UNOFFICIAL-arm64_bvS-vndklite.img
https://www.filehosting.org/file/details/8249475/GSI-Lineage-19.1_SM-T225_THL_T225XXU1AVB2.zip2
Here is GSI build for SM-T225_INS_T225XXU1AVB2
https://www.filehosting.org/file/details/7129248/GSI-12_SM-T225_INS_T225XXU1AVB2.zip2Successfully flashed GSI with magisk on my T220 following the OP's procedure. MTP is not working as the OP said. However, I can use my flash drive so I don't really miss MTP.
I chose "system-squeak-arm64-ab-vndklite-gapps-secure.img.xz" for GSI. "Treble Info" app can tell you what image would be compatible with your device.
If you want to use a different launcher like Nova instead of the default one, change the "Smallest width" setting from 600 to 598 in Developer options to hide the annoying taskbar.
AOSP-Mods and "Project Themer - Android 12+" work fine for me.
Here is my build for my device SM-T220 (SM-T220_EUX_T220XXU1AVE1):
GSI: system-squeak-arm64-ab-vndklite-gapps-secure.img.xz
Custom AP: https://www.filehosting.org/file/details/7045394/AP_TAR_MD5_CUSTOM_FILE_ODIN.tar.md5
Custom AP with Magisk patch: https://www.filehosting.org/file/details/7045714/magisk_patched-25101_cauJQ.tar
You can extract BL and Home_CSC from SM-T220_EUX_T220XXU1AVE1.
Notes: My device is actually SM-T220 XAR, but I have been updating it with SM-T220 EUX firmware versions without any issue.1
System lang is italian but should be easy to understand.
I found only a couple bugs so far in phhusson's GSI:
- in the launcher dragging apps from drawer to homescreen doesn't always work (just use another launcher)
- crashed once while searching in settings app
I use the tablet only for media consumption and some retrogaming, so there are probably other bugs i haven't noticed.
This is a generic guide, it won't include a "known issues" section since it largely depends on what GSI you choose.
I haven't tested this on the LTE version so i can't say for sure if mobile network works or not.
Unfortunately i don't have the time to make a custom ROM, test it and keep it updated here on the forum but maybe if there is enough interest someone will do it.
I hope other users will try to flash a GSI and share their experience here so we can gather some info on working/broken stuff, especially on the LTE model since i can't test that.
