Hey. I did everything on the guide but my wifi is not working. What i should do?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Go back to stock. Read post #422. This ROM was made for a much earlier version of Samsung's stock ROM and wifi doesn't work if you had the latest stock ROM. Sorry.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] sircrownguard:
Thanks for answer. Is there a more stable version of this ROM? Or will it even come out in the future?

Can I install this rom on SM-T503?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
The T503 uses a different SoC than the T500 but that shouldn't matter to a BgN or BvN GSI ROM. But if could well make a difference with the TWRP.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] BadRsT:
where I can find the vbmeta for T503? TWRP is necessary? I need to install this rom, because the stock rom is slow and not fluid

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jim in CA:
Yes, I did manage to fix the wifi issue! I started over following the procedure I found in this thread, and it seems to work fine on my SM-T500. I have used it for a few days and no issues, other than the charging issue while turned off. The Magisk module to fix the brightness slider.

I have a SM-T500 that had the latest stock firmware, T500XXU4CWA1. I have tried many times to update it to a GSI ROM, with no success. Every time I could install the GSI, but the wifi would not work.

I used Andy Yan's lineage-19.1-20230508-UNOFFICIAL-arm64_bgN-vndklite.img GSI. I did the optional step to turn off the encryption. This GSI includes Gapps, so no additional step was necessary to flash Gapps.

I did not experience the triggered reboots that Hausemaster documented in step 15. Just a smooth setup.

[SM-T505,T500,T507] Samsung Galaxy Tab A7 LTE GSI flashing guide [UPDATED] [Android 13 GSIs]

Just before we get started, I would like to say that you will not brick your device if you follow the steps as is without any, and I mean any deviations. Read what works and what doesn't first! Okay, enough preface, let's jump right in! Firstly...

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jim in CA:
I forgot to add that I found this thread in a separate thread, where the poster said it should work with the SM-T500. Just start using the stock firmware for the SM-T500, not the SM-T505.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] shrub100:
Have I bricked my device?

Just tried bootloading my SM-T500. I got to the point where I was using ODIN to download the OS (using the exact version / region as my device was already on) when ODIN reported the process as failed. At that point my device responded to say "An Error has occured while updating the device software".

I tried FRP HiJacker it states the fixing the softbrick error is ok. It then says "If device partition is corrupted, Willn't be fixed"?

Not really sure what to try next. This was a fresh newly acquired / second hand device so have no data on there, but equally I have never backed it up to a computer / cloud as it was already factory set.

Any advice highly welcome :) Sorry if this is in the wrong locations?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jim in CA:
For what its worth, you might try a newer version of ODIN. I see that you are using 3.14.1, whereas I have been using 3.14.4. All my work on the SM-T500 has been with that version. It looks like I might have gotten it in 2021.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] shrub100:
Thanks - I did that + found a different site for the source files (for some reason the new site files were larger by ~1gb) + used a different computer. From there it all went well. Got a bit paniced at 1am in the morning!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jim in CA:
If you are looking for the stock Samsung firmware, do a search for "frija". It is a tool developed by an XDA member to download directly from Samsung.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] shrub100:
So I have the device working using stock OS again. I cannot for the life of me get the updated OS from Magisk to work.

I am running Magisk 26.1 and odin 3.14.1.

I have a matching set of OS files to the OS that I have installed - including region (EU).

The OS files work fine to load as a non-rooted OS via ODIN.

What I flash the rooted OS with ODIN it passes.

Then my issue.... I cannot for the life of me get the OS into factory reset. When ODIN completes (It is set not to restart) I hold Power + Volume Down. When the screen turns off I quickly switch to Power + Volume up. I hold that and get several samsung screens; and android screen; what appears as a restart; more samsung screens and then a blue screen complaining that the OS is not genuine.

With the unrooted OS installed, I can get to factory reset, but not immediately after the OS has been installed. In fact, I have held Power + Volume Up right through to the screen that asks for my language.

What am I doing wrong here?

---------------------------------------------

Tried for the 4th time, it still would not go into recovery mode, but this time I did not end up with a blue screen saying I had an invalid OS, instead it booted into the OS and started the install / setting process. Very odd.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
What you are doing wrong is trying to go to recovery first. That is only required when flashing TWRP. When flashing the Magisk modified ROM, just let it reboot normally.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Raptorizex3:
hey, can someone please explain to me step by step how to install the updates? i am a boomer and just can't do it. installing the rom was hard enough and i could only do it with support. i would be very happy!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
I'm a pre-boomer and I can do it!! Unfortunately, the only way to "install updates" is to install the newer ROM the same way you did the old one. IE, format the data partition, factory reset wipe and use fastboot to flash the new ROM. Of course you should first backup anything you want to keep because formatting the data partition will erase everything.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Raptorizex3:
wow that doesn't help me. as i said: i was also helped then because i don't know how to deal with "fastboot".
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
There are instruction for using fastboot in this thread. All you need do is read them. I'm not going to post again what is already available.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] TheTimBrick:
When trying to download vbmeta_disabler Android Filehost gives either "Error" or "OOPS! no mirrors found." despite other download links working.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] TheTimBrick:
Did you ever fix this?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] dronkit:
(deleted)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Drakonas:
I had this issue. The fix is... keep holding it..... However, a bug... is that if you keep holding it, once the recovery actually shows up.... releasing the power button causes it to trigger the power button on the default selection: reboot. (WTF) If it reboots, just hold the vol up and power buttons again, and try your best to hold the two buttons right up until before the recovery would show up (should be after two reboots and seeing the "warning" message and then black screen). If done right, you will be able to select the data wipe on recovery.

Problem is, these instructions are now useless because the vbmeta_disabler file link is dead.

Does someone have it handy please? Would be really nice, because I can't install this ROM without it...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] TBacker:
Jim - You flashed this back in May. Do you have a working link to or copy of the vbmeta disabler file?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Why are you trying to go to recovery mode to begin with? That is totally un-necessary. After flashing modified OS, just let the tablet boot normally. You don't need to factory reset. You don't need to boot to recovery until you flash TWRP. And if you are going to use TWRP to install a custrom ROM, you don't need to root the stock ROM anyway.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jim in CA:
The flash procedure I successfully used does not use the vbmeta disabler file. I tried the procedure in this thread multiple times and could not get the wifi to work. I used a different procedure, as I documented in my post #435 back in May. It uses this disabler:

[Pie/10/11] [System-as-root] Multidisabler: disables encryption, Vaultkeeper, auto-flash of stock recovery, proca, wsm, cass, etc.

The multi-disabler started life on the Exynos S10 range, the first Samsung devices to launch with Android 9 (Pie). Since then, it has grown to support a great many Samsung devices running either Android 9, 10 or 11, and with either an Exynos or a...

xdaforums.com

I also used ODIN 3.14.4.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] TBacker:
Okay. I must be missing something in this other procedure. When I'm flashing anything in TWRP (disablers, the GSI image, etc.), TWRP cannot access the data partition (denied) and the screen is full of errors. Lineage tries to start afterward, but is perpetually stuck on the boot animation.

I think I'm just going to reload stock, root it, and not attempt this for the millionth time.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
You have to format, not just wipe, but format the data partition in order to flash anything with TWRP. I've had LOS 19 running on mine for close to a year.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jim in CA:
Suit yourself about going back to stock. A few weeks of using the stock rom convinced me to try LOS 19 again. I am glad I did. I used LOS 19 for a few weeks while traveling, and it worked flawlessly.

The "screen is full of errors" description sounds to me like the encryption is still on. I used the optional step to flash the two zip files to disable to it. TWRP can access the data partition and back it up during a backup procedure. (And just as importantly, during a restore procedure!)

And I agree with lewmur, you need to format the data, not just wipe, per the procedure.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] TBacker:
I finally got this loaded up. I've had pixel phones for quite a while now which are flashed very differently via ADB, so I lost my old knowledge of TWRP.

After flashing dynapatch, I:

Rebooted into recovery

Formatted data

Rebooted into recovery again

Continued the published steps from the GSI flashing thread.

A nights sleep cleared my frustration with this and led me to try again with the help from lewmur in mind.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
I just flashed LOS 19 20230611 bgN, installed Magisk via TWRP and everything appears to be working.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jim in CA:
I need to try the update as well. When you did the install of the GSI via TWRP, did you do a wipe? Reformat?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Yes, you ALWAYS need to format data when fastboot flashing via TWRP. The only exception would be if you kept the data partition un-encrypted using a vndklite ROM. I don't know if those work on the T500.

edit: To test if it would work, I dl the vndklite ROM and flash it, rebooted recovery, installed multi-disabler but it still encrypted the data when I boot to system. I don't know what to do to prevent it.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jim in CA:
Forgive my ignorance, but if you format data when flashing the update, are you then starting over from scratch with a new install and have to reinstall everything?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Yes, but that is your only option. Tell Google and Samsung thanks for the unwanted encryption.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jim in CA:
Success! I have been using the lineage-19.1-20230508-UNOFFICIAL-arm64_bgN-vndklite.img file on my T500 tablet(s). I have the encryption turned off. (This is a second tablet to the one I have been using for a month, which has had light usage. So not too much to lose if I screwed up.)

1. I did a TWRP backup of the boot, recovery, data, and super partitions to my SD card.

2. I flashed the lineage-19.1-20230611-UNOFFICIAL-arm64_bgN-vndklite.img file using TWRP.

3. From TWRP I did the format data step.

4. Without rebooting, I restored the data partition from my backup.

5. I rebooted to system. My setup and apps were all there, ready to use, and the LineageOS version has updated to the 0611 date. Encryption is still turned off. I can access both my internal storage and the SD card data from the tablet, and via a USB connection on my PC.

I also had to go back and copy the rest of my data from the internal storage that I had backed up to my PC.

I have lost track of how many times I have gotten into a boot loop and had to go back to ODIN and the stock firmware , and start over.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jim in CA:
The same procedure worked to update to lineage-20.0-20230507-UNOFFICIAL-arm64_bgN-vndklite.img. It is too early for me to know how well it works on this tablet. I just finished installing it.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] TBacker:
Has anyone experienced ghost touches on this tablet / ROM?

Particularly when charging, mine is going through regular bouts of random and frequent "ghost touches". Can't use it while charging. With it unplugged, it still does it but far less frequently.

Just bought this on Swappa, and fear I have purchased someone else's problem. I didn't use it much on the stock ROM, but I don't recall it happening on that.

I did clear the caches and check that "glove mode" was off - to no avail.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jim in CA:
I have not noticed any of that activity, but I don't tend to use it while charging very often.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jim in CA:
The easiest way is to turn on the Advanced Restart option toggle on the Power Menu options screen. Then select Restart and Recovery when you long press the power button. That is assuming you have a working Lineage and TWRP is installed. Or use ADB commands. I have never had much success using the button press method with this device.

thanks for the reply Jim....tbh it's so long ago I can't remember what I did lol

maybe TWRP isn't even on it.....it's running a version of lineageos from 2021 so I really need to update...

have you got a quick guide for the adb process please?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
That's not going to help boot to TWRP the first time BEFORE it boots to system and overwrites TWRP.

adb devices

adb reboot recovery

and wey hey TWRP comes up!

I've got TWRP 3.6.2_11-1......is that ok?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
I'm assuming you mean after you flash it in Odin and that you unchecked the auto-reboot option. Leave the USB cable plugged in. Hold the vol dn and power button for about 7 seconds. As soon as the screen blanks, switch from vol dn to vol up while still holding power button. Keep holding both buttons until red nag screen appears. Release the power button but keep holding vol up for a few seconds. That should boot to TWRP.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jim in CA:
That's the TWRP version I am using too.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jim in CA:
True, but from his post that's not what he is trying to do that. He has a working Lineage and TWRP, but just needs to get back into TWRP. (And he apparently now has done so.)

If you use this procedure in this thread you will likely have issues with the wifi not working.

is that this procedure?

'Flash multidisabler we downloaded earlier, along with disable dm Verity to disable FBE on integral storage. Also, if you intend to disable encryption, do flash both the zips not one'

Thanks!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jim in CA:
Yes, that is the one. If you disable encryption, TWRP can backup the data partition.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jim in CA:
For whatever reason, the tablet does not charge properly if the tablet is powered off. It needs to be turned on while recharging. A nuisance, but not a dealbreaker.

Do a Google search for frija. It is a software program designed by a XDA member to download stock Samsung firmware. There are a few websites that offer firmware downloads as well, but Frija works well.

{Mod edit: Quoted post has been deleted! Oswald Bolcke, Senior Moderator}

I hope you got that rant out of your system. BTW, 99% of it is dead wrong. First of all, what version of TWRP you use is of little importance. So long as it allows you to use fastboot mode, it will work. Second, the whole reason for adding fastboot to TWRP is that TWRP doesn't handle resizing of partitions. That what fastboot is for. As for Odin not seeing the tablet, that is because you are not in download mode. You can use fastboot or Odin, just not at the same time. Also, just who is this "you" you keep referring to. YOU need to realize that the people here are all either asking for help or trying to help and treating them with contempt is NOT called for.

edit: You also need to realize that this tablet has been around for quite awhile. What worked a year ago might not work with the latest Android version. Same with links to downloads. They may no longer link the versions that work. But no one is responsible for updating them. If you are not happy with the post explaining how to do, them maybe YOU should make the effort to post better ones instead of complaining.

The T503 uses a different SoC, so it may not. But us T500 owner have no way of knowing. The problem won't be with the ROM, which is GSI, but with the TWRP kernel. If it doesn't work, just flash the stock ROM to unbrick.
