Hi,

I am noob here, stuck at Step 5. I am getting “read failed: Invalid argument” after executing the command stated in the guide

./lpunpack super.ext4.img

Please help, been stuck here for few hours still can’t figure it out, am I missing something? My FW is SM-T220_XME_T220XXS1BVJ1

Thanks.

GOOD NEWS EVERYBODY...

For user who confused using windows script or wsl or linux

i have tested, and suceesed mod , using application termux.apk for android, to unpack and repack super.img.lz4

the first thing you open termux

launch code

apt upgrade

pkg install lz4

pkg install android-tools

you can put super.img in phone storage

then enter this code to select your current workspace

cd /

cd sdcard

congrats, you now can execute code lpmake,lpunpack,lz4,simg2img...

you can install zarchiver for extract tar

follow tutor in this first post to extract and mod your super.img

in termux you dont need ./lpunpack ./simg2img anymore,, you can use lpunpack simg2img instead without adding ./ in front of command

nb: i flash in odin.. only use super.img compressed to tar and vbmeta.img compressed to tar

select AP, in odin

i flashed super.img.tar (customed gsi), phone will bootloop, but dont panic, plug cable data, use power + vol- , until off, then hold vol+ and vol-, until odin mode appear

then flash vbmeta.img.tar

phone can boot into gsi normally..

i hope this reply can answer, user who confused using cmd command in windows,,, like me

You forgot to post the WSL output for each file size. To have that error you must have input some wrong numbers in there.

How do I get rid of warning signs?
[Samsung Galaxy Tab A7 Lite] abc1054:
Sorry , I mean bootloader warning splash and software warning.
[Samsung Galaxy Tab A7 Lite] nirogu325:
Follow this thread's instructions while using only post #11's file from that thread which is built specifically for Android 12. If you don't follow instructions, you'll brick the bootloader and would've to flash the bootloader file via ODIN to restore functionality.
[Samsung Galaxy Tab A7 Lite] abc1054:
Post #11 is wrong firmware for mine. Mine is T220XXS1BVJ2
[Samsung Galaxy Tab A7 Lite] nirogu325:
...come on, man. Read the Bootloader file name for VJ2. You'll see it ends with VGB. But if you still insist it's wrong then don't use it and make it yourself.
[Samsung Galaxy Tab A7 Lite] abc1054:
Thanks, everything worked. 😀
[Samsung Galaxy Tab A7 Lite] nirogu325:
Good.
[Samsung Galaxy Tab A7 Lite] abc1054:
Sorry, another problem, can't charge offline.
[Samsung Galaxy Tab A7 Lite] nirogu325:
That's out of my control. As far as I know some GSIs have the capability, some do not. I do not charge that way so I had no idea that particular GSI didn't have it and don't know which ones have it right now.
[Samsung Galaxy Tab A7 Lite] abc1054:
Thanks anyway. 😊
[Samsung Galaxy Tab A7 Lite] nirogu325:
I do, however, still have a 6 month old GSI that uses firmware VGB (still Android 12) and is known to have that capability. You'd have to downgrade to that firmware if interested.
[Samsung Galaxy Tab A7 Lite] abc1054:
Sure, but I am a noobi , don't know how to downgrade.
[Samsung Galaxy Tab A7 Lite] abc1054:
Sure, I can do it. It's just Android 12 firmware
[Samsung Galaxy Tab A7 Lite] abc1054:
Thanks. 🙂
[Samsung Galaxy Tab A7 Lite] abc1054:
I did everything ok, it works but still problem with charging . Same as before. Thanks for the custom ROM. I will just charge it when on. Thanks again 😁
[Samsung Galaxy Tab A7 Lite] dragonfly.12:
use odin , flash like usually... i have downgrade from android 12 bvgb to android 11 auj1 without any issue.

my device sm-t225
[Samsung Galaxy Tab A7 Lite] abc1054:
How can I downgrade, I heard that you cant downgrade android 12. I have T220XXS1
[Samsung Galaxy Tab A7 Lite] abc1054:
Charging was ok until I removed the splash screen.
[Samsung Galaxy Tab A7 Lite] dragonfly.12:
flash via odin, make sure you have selected correct firmware for your phone csc(country code)...

nb: for a7 lite android 11, android 12 , and android 13cvl5, bootloader rev version is still same.. so you can downgrade your phone with lower android version...

[Samsung Galaxy Tab A7 Lite] nirogu325:
All that "mod" does is replace literally two .jpeg images the system shows when booting. If you decompress it, you'll see the charging images intact and since the file only has images, that means the rest of the bootloader is untouched. No idea what really happened in your case.
[Samsung Galaxy Tab A7 Lite] abc1054:
well i did this, to take off the spash screen

dd if=/storage/emulated/0/Download/up_param.tar of=/dev/block/platform/bootdevice/by-name/up_param
[Samsung Galaxy Tab A7 Lite] abc1054:
i used this up_param.tar file
[Samsung Galaxy Tab A7 Lite] sandorex:
I did the same thing and bricked my device pretty hard

Have you tried reflashing whole firmware again
[Samsung Galaxy Tab A7 Lite] abc1054:
Yep
[Samsung Galaxy Tab A7 Lite] sandorex:
If that did not work then use mtkclient to flash whole firmware again, that worked for me

I can dm you instructions if you want
[Samsung Galaxy Tab A7 Lite] sandorex:
Successfully flashed pure android 13 GSI hurray!

I've minimized the otatools so it can be preserved easier than full 300mb archive it's now 4mb archive (7zipped)

3.74 MB file on MEGA

mega.nz

I may also see if i can rewrite tar-md5-script-tool in bash so this can be used on linux and fully automated, i just don't like the batch scripts

Although i did not test it, this is basically all the batch script does, it's much more readable and concise in shell i don't know why they wrote it in batch..

$ tar --create --format=gnu -b20 --quoting-style=escape --owner=0 --group=0 --totals --mode=644 -f AP_TAR_MD5_CUSTOM.tar *.lz4

Thanks Nirogu325..😁👍
[Samsung Galaxy Tab A7 Lite] abc1054:
Didn't work. I just put it in.
[Samsung Galaxy Tab A7 Lite] abc1054:
What's the difference between tar and md5. Odin didn't see it. All mine is md5 and odin see it.
[Samsung Galaxy Tab A7 Lite] abc1054:
I'm doing it manually..thanks anyway.
[Samsung Galaxy Tab A7 Lite] abc1054:
I just did it manually, it works great
[Samsung Galaxy Tab A7 Lite] sandorex:
Tar is archive format like zip, md5 suffix is telling odin to check integrity of the archive before allowing you to flash it, odin can actually flash .tar files but it is not recommended usually
[Samsung Galaxy Tab A7 Lite] abc1054:
Thanks, so what do I have to use ? Or put tar file in md5 file
[Samsung Galaxy Tab A7 Lite] sandorex:
Use my bash script to build it or use the batch script from this guide

Then flash the .tar.md5 in AP with original firmware BL CSC
[Samsung Galaxy Tab A7 Lite] abc1054:
I know that, but your tar file. It didn't work for me.. thanks
[Samsung Galaxy Tab A7 Lite] sandorex:
I dont understand what you mean, both scripts will make the .tar.md5 file

Thank you for sharing this! Just rooted and installed on my WA6 XAR T220. Do you have any recommendations for getting Bluetooth headphones to work better? I can get them to work sometimes only. It will either keep playing on device speakers or only play on headphones very quietly until I toggle a bunch of settings or reboot. Advice appreciated, thanks!
[Samsung Galaxy Tab A7 Lite] nirogu325:
No idea, sorry.
[Samsung Galaxy Tab A7 Lite] the_Victorian:
Thanks anyway! If anyone else using this GSI has the same prob and finds a solution please let me know
[Samsung Galaxy Tab A7 Lite] nirogu325:
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
[Samsung Galaxy Tab A7 Lite] the_Victorian:
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.

im a bit of a newbie when it comes to flashing custom roms so i struggle a bit when it comes to using things like fasbootD, it would make my life a lot easier if i could find a way to flash it with ODIN but i'll give fastbootD a shot
[Samsung Galaxy Tab A7 Lite] tom.android:
1.Extract your "recovery.img.lz4" from Your AP Firmware here. ( uses winzip or 7-zip)

2. I'll patch this "recovery.img.lz4" to recovery_fastbootD.tar then you must flash this tar file to replace old recovery.

3. When you have patched (boot.img+vbmeta.img) + recovery_fastbootD that I call it " 3in1.tar" then you can uses command to flash your own any GSI.

More detail please read my tutorial here https://xdaforums.com/t/rewrite-using-fastbootd.4544863/

FastbootD Command

=FastbootD===

adb devices

adb reboot fastboot

fastboot erase system

fastboot flash system PixelExperience_Plus_arm64-ab-vndklite-13.0-20230421-UNOFFICIAL.img

so im trying to use your guide but when i try to flash the vbmeta.img it gives me an "unknown command" error
[Samsung Galaxy Tab A7 Lite] tom.android:
-You can't uses fastbootd with vbmeta.

-Please make one tar file (boot.img.lz4 +vbmeta.img.lz4) then patch with magisk in your tab device.

Hello Nirogu325,

You get a lot of requests for tab a7 lite compilations. Can you make a compilation for my own tablet? Here are the firmware references: SM-T225_XEF_T225XXS3CWC2 (android 13). The gsi I'm interested in is LeOS or AOSP without GAPPs.

I've consulted a few compilation tutorials but, given my computer level, I don't feel equipped to do it by myself, on the other hand I know how to use Odin. If this is possible for you, I'd be grateful. (excuse my English translation).
[Samsung Galaxy Tab A7 Lite] tom.android:
if you can used odin why not to try fastbootD , only a little commands you will get any GSI run on your tab.

-LeOS -T is only run on T225 with exFAT sdcard supported.

-AOSP without Gapps , you should test with TrebleDroid before .
[Samsung Galaxy Tab A7 Lite] nirogu325:
I'm sorry but I no longer have the time to do that. If you don't know how to do these things, I suggest you stay with the stock Samsung system.
[Samsung Galaxy Tab A7 Lite] Madacam:
Hello, thank you for your follow-up and all your advice.

I have some practice with the adb and fastboot commands acquired on my nexus 7 flox as well as twrp. But, at the time, there was no vbmeta to manage... Since then, my custom rom installation references are no longer up to date.

But with all the xda tutorials, I hope to succeed in installing LeOS 20 gsi (pending on xubuntu and windows) with or without twrp, especially with the fastboot commands...

Thanks again for sharing your skills.

Given my level, I'm feeling a bit overwhelmed.

Maybe a solution?

Hello everyone, I followed the Sandorex tutorial: https://xdaforums.com/t/automated-gsi-build-script-linux-wsl.4541827/ , which allowed me to build 2 AP_CUSTOM.tar.md5, one on the magisk patched base, the other on the official firmware AP. I had to intuitively adapt the command line that was causing me problems by adding "bash": macadam@Macadam :~/Bureau/Construction GSI/buid-gsi.sh$ bash ./build-gsi.sh magisk_patched.tar LeOS-20 -VNDKLITE-arm64-bvN.img . Previously, I checked "allow this file to run as a program" for: lpunpack, lpmake and simg2img. Everything went smoothly on the xubuntu terminal and I was able to retrieve the AP_CUSTOM. I plan to flash tomorrow from odin on windows 10.

I'm hoping for a positive result; I'll keep you posted.

Hello everyone,

I flashed LeOS gsi android 13 on my tab a7 sm-t225 without any problem. I liked the "stripped down" look of the custom rom. All functionalities are operational. My only question concerns the banner at the base of the screen, which prevents me from browsing the screen smoothly and efficiently. I must have missed a step in building the custom rom... Does anyone have a solution? Even if it means rebuilding everything...

Have a nice day.
