You need to reboot the tablet to system, connect wifi, skip the rest of setup, make sure dev mode and OEM still enabled and then reboot to download mode after each flash. But you could have flashed both files in one flash by putting recover.tar in AP and vbmeta in USERDATA.

Hi,

Sorry for my confusion about this all....

Does this custom recovery also works for a Samsung Galaxy SM-T505 2020?

Thx for any confirmation :)

Bro you first have to unlock your bootloader before flashing any custom files

Yes I need to unlock the bootloader, but I can't go to Bootloader Mode without adb and Fastboot, I'll show you why I can't from these pictures and videos:

I wanted to bump this thread, i still haven't fixed my /keyrefuge issue, considering i flashed android 12 over android 11, considering i haven't messed with it because of life things and i forgot about it, has anyone had this same issue , cant replicate the issue without another tablet so idk.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AE0S:
What is the /keyruge issue? And then, how did you unlock the Bootloader in Android 12? On my Samsung Galaxy Tab A7 tablet I can't unlock it
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
The version of Android has nothing to do with unlocking the bootloader. How are you attempting to unlock it?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AE0S:
I tried to unlock the Bootloader with the Tablet keys, but it doesn't go into Bootloader unlock mode or Recovery.

I tried using ADB, entered Recovery mode, entered Bootloader mode (takes me into Fastboot), but doing the "fastboot oem unlock" command doesn't work.

In this answer I gave I put the Download Link of the video I made to explain why I can't unlock the Bootloader.

My tab was originally on Android 11 ,its not usually supposed to be able to update to android 12 originally , i unlocked the BL, and flashed twrp then flashed android 12 to it, and it worked but the firmware doesnt match the model or anything but it worked, just had a /keyrefuge issue ever since, /keyrefuge not found, essentially keeps me from factory resetting and any type of wiping the system even from twrp, just throws /keyrefuge, missing, i didnt play with it too much i didnt find it too much of an issue when i did it years ago, doesnt bother me all that much i just wanted to see if anyone come across the same issue and somehow fixed it (edit) to clear any confusion /keyrefuge isnt the same as the BL Key, i dont think i could be wrong. As well as the Storage Only says 4gb in storage, and its all taken up by system etc i have no idea how to fix it unless i manage to recover my old flash files And redo it originally the Tablet was 32gb from what i remember, once again i could be wrong i did this maybe a year or 2 ago
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AE0S:
If you want to try to Format the Device, I recommend using the ADB Drivers by doing "adb reboot recovery" and formatting from there, otherwise, I don't know what else to do.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
The only time I've seen that happen is when AP was flashed via Odin without the matching BL. After that the tablet would only boot to system. I don't think anything can be done about short of sending it to Samsung and that would probably cost more than buying a used A7 in good condition.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] CMTDev:
Everything works as intended doesn't bother me all that much just that one thing that it screwed up some way and i have tried resetting from twrp and just says keyrefuge error or something like that, i just wanted to see if anyone has come across the same issue as me,
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AE0S:
So it's just a hardware error?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AE0S:
Oh, okay
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Not really. It is a firmware issue but if you can't get to download or recovery modes, you have to way to correct the error.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AE0S:
I can access Recovery and Download Mode, but only with ADB Drivers, but it gives me errors in many commands, how do I correct the errors?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
If you can access download mode, and Odin show "Added", then you should be able to flash the latest stock ROM. But I don't understand how you can access Download and Recovery with ADB. I was able to boot to recovery with ADB but not download. Since I have TWRP installed, I can then reboot from it to download. Is that what you are doing?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AE0S:
To access Recovery mode with ADB just do "adb reboot recovery".

I can only flash the official firmware of the SM-T500, if I try to flash the unofficial TWRP, it doesn't work, because it says that I haven't unlocked the bootloader.

If I go into Bootloader mode (always with ADB) it goes into Fastboot mode, and I can't even unlock the Bootloader with commands.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Ahhh!!! You can't unlock the bootloader without using the buttons. Turn the tablet off. Plug the cable into the PC but not the tablet. Hold down both vol up and down and then plug the cable into the tablet. When the screen appears, release the buttons and then press and hold the vol up until the unlock screen appears. That is the ONLY way to unlock the bootloader.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AE0S:
In this way? (In this way? (I don't think it worked, I know what the bootloader screen is, but I can't access it): https://www.mediafire.com/file/0ra2zgpjnzb52pr/Works,+I+don't+know.mp4/file
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
No!!!! Follow the instruction I gave EXACTLY. You are only holding ONE button in that video and I don't see you plugging in the USB cable at all. BTW, the volume button isn't a "rocker switch". It is actually two separate switches and you need to hold down BOTH ends and then plug in the USB cable. Also, the power button isn't used at all. Plugging the cable while holding down the two buttons will turn it on.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AE0S:
Ok, but I don't understand, what should I do with the USB cable connected to the computer?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
PLUG IT INTO THE TABLET WHILE HOLDING DOWN BOTH BUTTONS!!!! Continue holding the buttons for a few seconds till the screen turns on. But you can't plug it in TILL you are pressing the buttons. DON't try plugging it in and THEN pressing them.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AE0S:
I have I'm already telling you, I've been trying to unlock the Bootloader for a year, but the keys have never worked, I think I've also used this method, anyway now I'll try and tell you.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AE0S:
Ok, thanks, it worked, it's the first time I've been able to enter Download mode without ADB, now what do I do?: https://www.mediafire.com/file/erc2ntufpgmgle0/Okay,+working.mp4/file
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
If you reached download mode, you went to far. Start over and when you reach the first screen, READ IT. It tells you what to do to either unlock the bootloader or proceed to download mode.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AE0S:
Thank you very much, I got to the customization of the Tablet, so you formatted it for me, obviously, now should I be able to install the unofficial TWRP?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Not yet. After unlocking, you will need to boot to the system, connect to wifi but skip the rest of the setup. Then re-enable dev mode and OEM. And if you actually succeeded in unlocking, you should now be getting a nag screen when you power telling you that you aren't running genuine software. That is just the price you pay for unlocking. Once that is done, you can start the customizing. https://xdaforums.com/t/sm-t507-t50...e-it-for-those-who-dont-know-gsi-rom.4536025/
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AE0S:
Yes, I get that annoying screen, and also in Developer settings, OEM Unlock tells me "Bootloader already unlocked"
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AE0S:
This is the result, I can't even restart the Tablet anymore
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
This is the result of what????

edit: Whatever you did, it would appear that you DID NOT flash a blank vbmeta file.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
There are only two ways to get out of that mess. The long way is to wait several days for the tablet's battery to run down and then use the normal method of holding vol up and down and inserting the USB cable. Or the short but tricky way. The timing on this method has to be just right for it to work, so you may have to try it several times to get it to work. Partially insert the USB cable into the tablet, but not far enough to connect. This is so that when the time comes, you can quickly finish inserting it. Now, hold down the power and vol down button for about 7 seconds. The instant the screen blanks. switch your finger from the power button to the vol up and finish plugging in the USB cable. This should get you back to the download screen. Now use Odin to flash the latest stock ROM.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AE0S:
I flashed the File recovery.

However I solved it, I reset the Firmware, what is vbeta anyway?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
vbmeta is what checks that you are flashing "genuine" firmware. The problem you are facing is that you are very late to flashing for the first time. The instruction you need are now very old. None of the recent threads give instructions on flashing for the first time. When flashing the recovery.tar in AP you also need to flash a blank vbmeta.tar in Userdata. To create this file, open any text editor like Notebook or Wordpad and create a new document. Leave it blank and save is as vbmeta.img. Then use 7-zip to tar it.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AE0S:
So a blank document is enough? (I don't think an empty document makes sense, it's like creating a Batch File with nothing written, but if so, that's how it is, I'll try, thanks).
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
If you read the instructions in the first post in this thread you would see this

Do you see the line that says "Flash Blank vbmeta via Userdata"?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AE0S:
The file I created didn't work, I found it online but TWRP keeps restarting continuously: https://www.mediafire.com/file/zxf7wzxig90hdvp/YouCut_20231024_200855365.mp4/file
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Why are you choosing "Turn Off" rather than "System" when rebooting? Also, I don't know what you "found online"? It may or may not be what's needed. Different models of Samsung tablets require different vbmeta files. This one just needs a blank one. Stop trying to second guess the instructions. Don't you think that if they were wrong, someone would have corrected them by now? But since you succeeded in flashing TWRP, it obviously worked.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AE0S:
I tried to reboot the system, but TWRP stuck as the main boot
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AE0S:
Can I solve this by resetting the firmware?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Have you tried /Advanced/Terminal exit_twrp? What version of TWRP did you install?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AE0S:
I installed the TWRP that is in this discussion, however I reset the Firmware, my goal is to put the Root, with Magisk where the boot.img file goes wrong, I don't know what to do.

When I add the boot.img file to a TAR archive, Magisk takes it from me, but Flashing it with Odin doesn't work, I don't know what to do.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
I currently own 4 different models of Samsung tablets and have owned several other over the years. I have learned the hard way that no two of them do things in exactly the same way. If you go to the quide threads and look for the quide for rooting this tablet with magisk, I think you'll find that you need to modify the entire AP file with Magisk and not just the boot.img portion.

I was successful in installing twrp on my galaxy tab a7, I only had to install up to the latest version of the Samsung Android 12 operating system and the latest security patch and unlock the bootloader and that's it, the first time I had to reinstall the system again because I followed another guide but this guide helped me and I installed lineage os 20 official from the lineage os site and if there is a lot of difference there are no jerks and everything goes faster instead of having one ui by default.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Peter12205:
put where it says AP the twrp recovery and vm beta where it says user data, apparently that's why it's failing, if it's still failing it's because you don't have the latest version on your galaxy tab a7 or the botolader unlocked and I understand you since I still went through the same error that I had to reload the system.

Before doing the other thing, have the autoreboot turned off to be able to enter the recovery mode and from there flash the rom, be careful here at least the first time I stayed in a loop even doing a cleaning of the system where it says advanced cleaning, so if not Go from there, give it a simple cleaning and put yes and that's it, with that it will start Android 13

This was the thread I used first, I don't remember if I used the files here to have twrp or the ones in this other guide, you can still try, just use vm beta and twrp, don't use other things since at least for me they weren't necessary , greetings from Mexico

[ROM][SM-T500] Samsung Galaxy Tab A7 10.4 (2020) - LineageOS 19.1 (and TWRP 3.6.1)

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...

xdaforums.com

I'll still leave you a video of how you should insert the files, this video was the one I used after using the first guide and being left without a system, remember it is only a video on how to insert them, do not download any of that video since it is a different variant and I am not responsible for bricking your tablet, I am just giving you a little help and a brief summary of what I did to have twrp and lineage os

I leave you a link from where I got the gapps, which are Google services so that you don't have that problem of not being able to log in, I used the gapps NikGapps-omni-arm64-13-20240127-signed.zip these gapps are from a android 13 forum on an s8/s8+/note 8 by @Ivan_Meler but they work the same on the galaxy tab a7 if you are going to use the official lineage os compilation

Hi Peter,

I successfully installed TWRP 3.6.1 Beta5 on my SM-T500 with the stock Samsung A12 FW. I then successfully replaced it with LineageOS 20, including the Lineage Recovery.

I would like to install TWRP to replace the Lineage Recovery but I am fearful of screwing something up, because the TWRP is based on A12 (I think) and the LOS is A13.

Can you advise whether this will work or should I wait until someone comes up with a TWRP version for A13 and SM-T500? I am a newbie with Android and had very many false starts before finally getting LOS 20 installed... I'd hate to mess it up. :)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AE0S:
How did you install Lineage OS (I tried, but I messed up and reset the firmware)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] MikeMillen:
I started out by flashing the latest stock Samsung FW with Odin, then I followed the instructions here:

https://wiki.lineageos.org/devices/gta4lwifi/

VERY CAREFULLY! :)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Peter12205:
well at least with the twrp recovery from this guide the official android 13 lineage worked, it just had the problem that the tablet did not want to turn on when I left it on for a short time or that the internal storage then had failures when flashing the gapps or the same lineage is in twrp, so yes this recovery is useful for that but it is not yet well done to have it in recovery forever and if it is for convenience you can live with twrp without any problem.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] MikeMillen:
Thanks, Peter.

So it seems I should wait until someone builds a TWRP for SM-T500 + A13. For now I'll stick with the Lineage Recovery.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Peter12205:
Easy, I went to the lineage os site and looked for my device and the variant, in this case the wifi variant, download only the zip of the custom rom and install it from this twrp recovery from this guide with the gapps that I left above and that's it.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Peter12205:

If you flash the bgN version of LOS 20 you won't need to flash gapps. The "g" means it already has gapps.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Peter12205:
disadvantage, the gsi rom is already rotated even if you install the N variant, which is the non-root one, so it is easier for someone to install the official rom so as not to have problems in everyday apps.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
It is no big deal to root a the N version of a GSI ROM and a big advantage to have a debloated ROM. I always choose a custom ROM over stock whenever I can and the only app I've ever heard people having a problem with is Netflix playing in high def. IMO, high def on the small screen of a tablet is overkill.
