so i can't install your rom...

It's not my ROM and I don't know if you can or not. Did you do as I suggested and look for post from others with the problem?

edit: I don't know if it will work or not, but you might try flashing just the CSC for your country via Odin.

 

[ljgjm]

I think that may because this ROM is based on the US/Canada stock ROM. If your stock ROM is from another country, then that is the problem. If you search back through this thread, I think you'll find others had the same problem but I don't know if they ever solved it.

My stock rom is XSG but it still worked (i got it online lol cus it was cheap lol 100$ less just more delivery payment)

Is there a mirror for the files? It seems like Androidhost is having some issues, can't download the files.

 

[aladinliverpool]

anyone out there with a copy of the files on here. i think someone hasn't paid their hosting bill on Cloudflare.

I just clicked on the files in the OP and had no problem downloading.

 

[samigina]

Yeah, the links are working again.

Hello world, I have successfully built LineageOS 19.1 with Gapps for the SM-T500 (Tab A7 10.4 2020) using Andy Yan's LOS GSIs. Lineage is current as of 3/24/2022. I have also compiled TWRP version 3.6.1, based on Android 11 (previous release was Android 10-based). I have attempted to make this install as painless as possible. Please read the notes below carefully. WARNING: you are responsible for your own actions, so please be careful. If you brick something, that's on you.

1. Update to latest stock ROM as of 3/24/2022 (T500XXU3BVB3).
2. Unlock bootloader using steps described in this thread. Make sure that after your device wipes and reboots after the bootloader is unlocked that you go through the setup wizard again and back into Developer Settings and enable OEM Unlocking. I think you need to connect to wifi for this option to appear, so if you don't see it try that.
3. Boot to download mode, then install VBMeta Disabler via Odin.
4. Reboot to download mode, then install TWRP via Odin.
5. Reboot to download mode again, then install LineageOS via Odin.
6. Boot to TWRP, push "fix_brightness.sh" to the device and run it, then format data.

That should be all that is necessary. If you get stuck in a loop with TWRP where you can't boot to system (seems to happen regularly to me) I included a script in TWRP that should get you out. From the TWRP cli run the command "exit_twrp". It will say "out of space" when finished (instantly). Then reboot to system. If for some reason that still doesn't work and you boot back to TWRP, repeat.

Known Issues:

• OS-encrypted storage (Internal Data) not able to be decrypted in TWRP.
• TWRP touchscreen seems to be unresponsive for several seconds upon first booting into TWRP. Just patiently wait a few seconds and try again.
• You'll see errors in TWRP about /keyrefuge, etc. Ignore that. I believe it's related to the inability to decrypt internal storage using FBE.
• Installing Gapps (Nik and Flame) doesn't work, but no worry because the ROM includes Gapps
• Security: by default this ROM has root access and USB debugging (adb) is enabled unsecured. Anyone can plug into it and have full root access. So disable USB debugging if you don't want that! TWRP is the same way, though data is encrypted. Someone could install malware into your system partition though. In short, this is for hobbyists, not someone with security concerns.

• Kernel sources from Samsung: https://opensource.samsung.com/uploadSearch?searchValue=Sm-t500#

Files:

• LineageOS 19.1 Beta2
• TWRP 3.6.1 Beta 5
• VB Meta Disabler
• Brightness Fix

Updates:

• You can update this ROM yourself by installing a new GSI to the system partition.
  • Download new GSI from here onto Micro SD card: https://sourceforge.net/projects/andyyan-gsi/files/lineage-19.x/
  • Boot into TWRP
  • Run command: blockdev --setrw /dev/block/mapper/system
  • Run command: dd if=/external_sd/<your_downloaded_gsi.img> of=/dev/block/mapper/system bs=1M
  • Wait for dd command to finish, then reboot into system. Don't forget to use "exit_twrp" command if you keep booting into TWRP.

hello I've got some questions, for start my wifi is not working or auto rotate or volume is there any fix for this?

Did you unlock the bootloader? Did you enable Dev mode and OEM after unlocking?

 

[axltrsx]

Did you unlock the bootloader? Did you enable Dev mode and OEM after unlocking?

Yes, but still, it gave that error

Now it says "partition vbmeta
Reason vbmeta: error verifying vbmeta image: HS_IMTHSGAUEMSAC"
Odin detects it but when i click start, this shows in logs:

<ID:0/006> Odin engine v(ID:3.1303)..
<ID:0/006> File analysis..
<OSM> All threads completed. (succeed 0 / failed 1)

"reboots after the bootloader is unlocked that you go through the setup wizard again and back into Developer Settings and enable OEM Unlocking. I think you need to connect to wifi for this option to appear, so if you don't see it try that."

After doing this, does "OEM unlocking" show in Dev Options?

Yes, it did.

So, vbmeta installed OK. If you got this far into flashing "super.img", you must have a corrupted download or your stock ROM version is later than the one used by the OP.
