Without knowing what you have and haven't done, and what stock version you started with, it's hard to tell what you need to do next. But to start, use frija.exe to download the latest stock ROM.

My Phone suddenly rebooted and it said reboot recovery cause is (unknown). Then I tried to flash it with the latest firmware and the flash failed then it said sw rev check fail bootloader device -1. Does firmware -1 exist?
[Samsung Galaxy Tab A series Guides, News, & Discus] lewmur:
You can't flash anything without having first enabled Dev mode. I would suggest you boot your tablet to recovery and factory reset it.
[Samsung Galaxy Tab A series Guides, News, & Discus] Doto143:
I already want to try that. But unfortunately I can't enter recovery mode. I think it's because my phone suddenly turned off and this writing appeared.

okay thank you
[Samsung Galaxy Tab A series Guides, News, & Discus] chalybeum:
Did you call them allready? What did they say?

Have you tried to reach download mode? You can try to reflash the failing parts via Heimdall. Or everything together again with Odin. Since ypur warranty is void anyway I don't believe Samsung will be a great help here.

I just received my A7 and went through the normal setup routine. Installed a 64gb SD card and while the apps remainded on the internal, all of the user data, such as Downloads, DCIM, Android, Movises, Music etc, were all moved to the SD card. I know when tablets only had 8gb internal, moving apps to the SD card was needed. But even before I started removing or disabling unwanted bloat, only about 15gb of internal storage was used. I don't know if people realize just how much slower SD cards are compared to internal storage, but it is really significant. Personally, I wouldn't want to move apps to SD unless I absolutely had to.

Again, I know there are gamers who really need a lot of internal, but , in that case, why buy a tablet with only 32gb in the first place? I really don't understand, When I bought mine, the 64gb version only cost $10 more than the 32gb.

I haven't tried since, and nah I have the T500. I had intentions of installing another OS (Like Lineage or Ubuntu Touch) but they don't support the device yet so I can wait.

Got the same error. Only Official released binaries are allowed to be flashed (vbmeta)

Someone knows why!? I Tried to root 10 times. shows me always the same error. =(
[Samsung Galaxy Tab A series Guides, News, & Discus] adjalex:
Hi, just a quick tip and suggestion for people rooting Android 11: to get into recovery mode in step 7, you need to hold Power and Volume Down key for 7 seconds and then release the Power key and keep holding the Volume Down button as soon as you see the first screen appear.

Release Volume Down button when you are in Recovery Mode.
[Samsung Galaxy Tab A series Guides, News, & Discus] Moose84:
Hi.

First of all I want to say, excellent guide.

After reading about how people were having some trouble after rooting I jumped to step 7 immediately to simulate and learn how to enter the recovery mode again.

Now I have no idea what Samsung has been doing with the Android 11 update but I simply can't enter Recovery mode after updating my SM-T500 to Android 11. At least not the old fashioned way.

After a quick google search I found a video that sounded like absolute hogwash until I tried it. The only way to enter Recovery Mode is by having a USB cable connected to the Tablet + Vol up + Power key.

How bizarre is that? Is this happening to anyone else with the non-LTE (or even the LTE) version of the Tablet on Android 11?
[Samsung Galaxy Tab A series Guides, News, & Discus] JaneValley:
Hello, thank you for you guide!

Can I flash T505's firmware to T500? I checked on official website, they are basically the same except T505 have 4G support. I really want the OneUI 3.1 update.
[Samsung Galaxy Tab A series Guides, News, & Discus] lewmur:
If it was that simple, why hasn't Samsung released it for the T500? I've been flashing custom ROMs on Tab As for about 5 yrs and have NEVER seen a ROM that worked on both LTE and wifi only tablets.
[Samsung Galaxy Tab A series Guides, News, & Discus] spkuja:
Is anyone else having trouble getting into the recovery mode after flashing? Holding both the power and up buttons just reboots the tablet before it gets to recovery. The problem I'm having is the warning about the bootloader being unlocked requires me to press the power button to skip it, so holding up and power is just rebooting the tablet
[Samsung Galaxy Tab A series Guides, News, & Discus] Moose84:
The OneUI 3.1 update for the T500 is released in some parts of the world already. I received it last week in the EEA.

@spkuja

As for entering recovery mode after the update, connect a USB to your Tablet before attempting to enter recovery mode. This seems to be the new norm for entering recovery mode after Android 11.
[Samsung Galaxy Tab A series Guides, News, & Discus] spkuja:
That worked like a charm, thank you!
[Samsung Galaxy Tab A series Guides, News, & Discus] Mogster2K:

The CSC code for this in Frija.exe is EUX and it is downloading. But very slowly.

edit: Download succeeded and installed AP, BL and HOME via Odin. Even though I'm in the U.S., everything appears to be working OK. The only difference I know of are the wifi channels. I ran an analyzer app and both 2.4 and 5ghz channels seem to be working.
[Samsung Galaxy Tab A series Guides, News, & Discus] myxiplx:
Folks, I really need some help with this. I've followed these instructions and tried flashing this tablet 4-5 times now. Every single time it locks up on boot with a "Security Error", and I'm having to wait a full week between each attempt to clear the "KG STATUS : PRENORMAL".

I've worked through the entire guide, right up to the step where you factory erase the firmware and reboot. The problem is I can't get to the step after that where you open the Magisk app. Before I can get to that, the tablet is opening the welcome wizard, and at step 3, after selecting the language options the only choice is "reboot". If you reboot at that point, the tablet locks up with:

"Security Error: This device has been flashed with unauthorized software & is locked."

I've tried several times, and have even tried the workaround listed in post 140 which states to avoid the forced reboot by going back and entering the accessibility menu, but that simply changed the setup to prompting me to scan a QR code. Once it had gone into the QR setup I couldn't find any way to bypass or get past that step, and of course attempting to reboot locked the tablet again with the security error.

How the heck do you get to that final step to finish rooting this device? I need to understand how to boot to this point after the factory reset:
[Samsung Galaxy Tab A series Guides, News, & Discus] scarymoviesg:
Hi guys, I rooted my A7 successfully. However, the only problem I have is that it always seem to run out of memory and has to soft reset itself everytime when I'm using it. Do you experience this?

[Samsung Galaxy Tab A series Guides, News, & Discus] lewmur:
No. I haven't attempted to root. The post is outdated. I merely used it to get Android 11 stock before it was released in the U.S. I'm waiting for a custom ROM before attempting to root.
[Samsung Galaxy Tab A series Guides, News, & Discus] jdegreef:
Ah, ok :)

PS : is it me or the "thanks" button has disappeared from the form ?
[Samsung Galaxy Tab A series Guides, News, & Discus] Frankyg:
I just got my T505 today and jumped to this, so thanks for the guide!

Mostly straightforward until step 7 as has been mentioned a couple of times. Mine seemed to loop a couple of times until I was presented with a recovery screen that wasn't the same as the one in the guide, but it did allow me to wipe data/factory reset which I did.

After that, rebooting, setting up internet and installing Magisk again I used a root checker to verify root. All seems good and I've installed a couple of apps (titanium backup) and swift backup with root access.

Safetynet check fails though with ctsprofile failure. Any idea why? That was after installing the full magisk app.

Thanks again,
[Samsung Galaxy Tab A series Guides, News, & Discus] agreenbhm:
Thanks OP for the guide.

For anyone who may be interested: I'm working on porting TWRP (with the end-goal of Lineage) to the SM-T500. I currently have a beta copy of TWRP working enough to test with. Not working: touch-screen (but you can access via adb or by using a usb mouse). Since this is the first I'm aware of TWRP running on this device, I thought I'd post it here for others to test and hopefully contribute. I can't figure out what's wrong with the touchscreen, but maybe someone else can.

You can find the WIP here: https://github.com/agreenbhm/android_device_samsung_gta4lwifi/releases/tag/v1.0-beta1

Make sure your device is unlocked first, then flash the vbmeta_disabler_r.tar file available in other threads via ODIN in the USERDATA slot to allow non-signed images to boot. Then, flash the TWRP recovery.tar using ODIN in the AP slot. NOTE: you may very well end up needing to wipe your device either while installing this or as a result of something going wrong, so this is your warning not to use this on a device with data you care about. After you have successfully booted to TWRP (hold down power + vol-up while booting) run the tool "multidisabler" from the TWRP cli to make adjustments to the system to allow persistence and other tweaks.

Guys, I was looking for forums about the SM-T500 and ended up finding several, but none that were completely helpful, so I wish we could in this post talk about how to create and actually create a working TWRP, or a way to get to TWRP or other recovery, I'm still a beginner at this, so I need your help.

I saw that one person on this forum: https://xdaforums.com/t/guide-sm-t5...k-bootloader-root-with-magisk.4185993/page-12

Was able to create a TWRP that towtch screen does not work.

quick question can you relock the bootloader the same way? I hate having to hit the power button twice to turn the thing on...

(edit) got inpatient for an answer and managed to mess things up somehow... Firstly I rebooted and was stuck in a boot loop. I was unable to get into recovery. When I did manage to get into download mode I held the volume up key but no menu showed and I had a black screen. When I rebooted it would only go into download mode. So I tried to flash bl, patched ap, and home csc. Resulted in fail. I noticed that it now said that the device was oem locked. So I flashed again but with the non patched ap and the csc home. Resulted in bootloop even after wiping cache (good news the original recovery was back) next boot loop brought me to recovery and said data may be corrupted and gave me only option to factory reset. Factory Reset brought everything back normal however I will have to start all over just to get root again. Not a big deal but honestly I kinda like the bootloader locked as I dont get the warning pop up now when starting the device. It would have been nice to know if I could re-lock it with the rooted package installed. If anyone knows if this would work it would be really nice to know thanks. And don't do what I did it will frustrate the heck out of you lol.
[Samsung Galaxy Tab A series Guides, News, & Discus] agreenbhm:
I'm the one who made that TWRP port. I feel like someone with experience doing this could easily get touch working. I just can't seem to pinpoint whatever setting is off. There are folks on xda who have made twrp ports for lots of Samsung devices. If you dm one of them we may be able to get help. My device is out of service for the next few weeks so I can't do further development at the moment.

I have a question about step 8 in paragraph 3: HOW THE HELL you easily turn off your Tab after downolading the modified ROM without Autoreboot on Odin? I tried so much buttons combinations with different timings... but no one didn`t power off my Tab....

When i check AutoReboot on flashing ROM, then i can go into stock recovery, but when i checkoff AutoReboot then i didn`t go into stock recovery.... (android 11 requires usb cable ON when you need to go into recovery and combination Vol+ and Power) but after all i didn`t get the magisk app on my app drawer but i did all things that you describing in guide :c

after one day of my tries that i used the original part of guide and now i get magisk app on my app drawer)

i understand that my T510 is another device but T505 and my Tab have much soft identity and you wrote guide based on original from Magisk creator and i think your advices will be compatible/useful for T510. i will be grateful if you help and give a solution on that problem an some answers for difficult moments)
[Samsung Galaxy Tab A series Guides, News, & Discus] nobasband:
To Root the Tab A7 T-500 is the simplke thing to do : you need only Magisk, after you did flash the original AP - (and unlock Bootloader first) you will stuck twice : 1) push on/off button to pass first message - (you will never get rid of the messages - but it doesnt matter) than you will get to chosse Country & Language - this is the point were it will restart and you will stuck!! just go to accessibility and jump "back & forth" a few times - now you passed without restart! IMPORTANT - if your Tab will stop during Odin already : YOUJ MUST EXTRACT THE PIT FILE from CSC or one of those 3 files you got - then enter PIT on Odin, then it will repartition automatically (you will see, it does it byself) there you go!!!! the rest ist just updating Magisk App......
