Hello Pamela! I'm sorry for the delay.

I never received this message, but try to backup your files and format.

But if you can install the recovery and boot to the system, you can root our stock ROM installing SuperSu. then we can have our USB back working.

---------- Post added at 11:28 PM ---------- Previous post was at 11:25 PM ----------

thenks for that :), now we can root the stock ROM through TWRP!

I'm think it's because of the vbmeta file, download this vbmeta, flash the recovery and flash the vbmeta.
[Samsung Galaxy A21s Questions & Answers] PamelaGirl:
Hello President Wer99,

I can be the tester to install the recovery with the hope of rooting the stock ROM.

Where would I start?

Thanks
[Samsung Galaxy A21s Questions & Answers] Wer99:
Haha, thanks :). Yes you can, here is the guide.

Flash the recovery and flash this vbmeta to fix the recovery boot. Extract your stock AP_XXXX_XXXX.md5 and flash the super.img.lz4 (create a .tar). Wait the phone to install. Download SuperSU-v2.82 zip, and copy it to your sdcard, boot to your recovery and Install it. That's it!

If it did not work then we need to install it manually or use another root method.

---------- Post added at 12:19 AM ---------- Previous post was at 12:08 AM ----------

If your TWRP is not reading the sdcard and showing random files (my case) then we need to install it through TWRP terminal. Let me know.
[Samsung Galaxy A21s Questions & Answers] Wer99:
As I expected it did not read or mount the SDcard. So we need to use Adb instead.

Follow this procedures.

1. Boot into recovery

2. Open Advanced > Adb sideload, and Swipe.

3. Connect your phone to your PC

4. Download Minimal ADB and Fastboot and Install it.

5. Open the Minimal ADB folder. Usually at "C:\Program Files (x86)\Minimal ADB and Fastboot" Move SuperSU zip to that folder.

6. Open cmd-here.exe and use this commands:

adb devices (See if "XXXXXXX recovery" shows up, if not install this driver)

Then

adb push "\Folder\Super_SU.zip" /data/tmp, example: adb push "C:\Program Files (x86)\Minimal ADB and Fastboot\SuperSU-v2.82.zip" /data/tmp , with cotes.

7. Go back to your TWRP and open, Install > (Up A Level) > /data > /tmp and your SuperSU.zip should be there.

8 Select and Install!

9. Or use this command: adb shell twrp install /data/tmp/SuperSU-v2.82.zip and wait it installs.

Let me know if you found any error. thanks for testing. :cowboy: I tested it using Magisk zip (Just for test to see if it works) it installed but I got boot loot :S.
[Samsung Galaxy A21s Questions & Answers] SeleznevS:
You can decrypt /data and /storage/emulated/0(/sdcard) if you format data in wipe button(After Reboot).
[Samsung Galaxy A21s Questions & Answers] Wer99:
It should be some TWRP error, the /data and /storage/emulated/0/sdcard is not encrypted.
[Samsung Galaxy A21s Questions & Answers] SeleznevS:
No. Im test it and this works
[Samsung Galaxy A21s Questions & Answers] PamelaGirl:
Hello President Wer99,

Thank you for all the response.

It took some time but I was able to get the SuperSU.zip pushed to the device and installed. The install failed.

What is my next step?

Thanks
[Samsung Galaxy A21s Questions & Answers] Wer99:
Hello Pamela! Thanks for sharing the image. It's showing this error because it's missing the unzip binary at /sbin folder, probably it's at /system/bin/. So I edited the SuperSU, and redirected to system partition. Try it.

If did not work, extract and push this unzip binary to /system/bin/ .

1. Open Mount, and enable System.

2. Use this code

adb push "...\folder\unzip" /system/bin/
[Samsung Galaxy A21s Questions & Answers] PamelaGirl:
Hello President Wer99!,

Thanks for the new files, the SuperSU2.zip did the trick...SUCCESS!

Do I need to wipe cache/dalvik or simple reboot system?

Ready for the next step.

Thank you :)
[Samsung Galaxy A21s Questions & Answers] Wer99:
Ohh Great!!! Thank you Pamela! No need you can reboot.

This is exciting!
[Samsung Galaxy A21s Questions & Answers] Wer99:
It's great! Thank you. The root worked?
[Samsung Galaxy A21s Questions & Answers] PamelaGirl:
Thank you!

I think it worked, the system booted up fine. I do not see an additional icon, just the original one included in your Android 10 ROM.

Root Checker says:

Congratulations! This device has root access!
[Samsung Galaxy A21s Questions & Answers] Wer99:
Then everything worked. That's great, now we can root the Stock Rom!! Congratulations Pamela!
[Samsung Galaxy A21s Questions & Answers] PamelaGirl:
All thanks goes to you!

This is was a quiet forum till you arrived with much goodness!

You’re the programmer and I am test that can follow good instructions. I appreciate you. I appreciate your time and work!

Now President Wer99,

How would we go able rooting the Stock Rom?

Thank you
[Samsung Galaxy A21s Questions & Answers] Wer99:
Thanks Pamela I really appreciate what you said :D . But all thanks to you and everyone who contributed with this forum always making it active and helping others, now we get a little attention from the really experts and some people that is interest in sharing their ideas, and so we have a Recovery and more methods is possible. Sorry for English mistakes I doing possible to make it understandable..

How would we go able rooting the Stock Rom?

I sure that everyone can root the Stock Rom with SuperSU and TWRP, if not, there is another way.
[Samsung Galaxy A21s Questions & Answers] PamelaGirl:
I have been around the XDA forum for over 10yrs now and have met some really good and people, you are one of them for sure. All the many people that have contributed to this thread I give a thanks too!

Your English is very good.

Now that we have root and a recovery how exactly do we root the Stock Rom?
[Samsung Galaxy A21s Questions & Answers] Wer99:
Thanks for that. Doing the same method as you did, backup your files, flash your stock Rom (the super.img.lz4 only), wipe your data* and install the SuperSU zip file.
[Samsung Galaxy A21s Questions & Answers] PamelaGirl:
Is this correct steps from start to finish?

1. Install Samsung stock Android 10 Rom.

2. Flash the Recovery file

3. Flash the AP_vmeta.tar file

4. Boot into recovery and install SuperSU

5. Reboot device and enjoy root access.

Is this correct?

Thanks :)
[Samsung Galaxy A21s Questions & Answers] Wer99:
1. Yes

2. No. Already flashed

3. No. Already flashed

4. Yes

5. Yes

The correct way

1. Install Samsung stock (the super.img.lz4 only, you can get it extracting AP_A217MXXXXXXXX_CLXXXXXXX_XXXXX.md5 file, create a tar and flash) Android 10 Rom.

2. Boot into recovery and install SuperSU2 as you did.

3. Reboot device and enjoy root access.
[Samsung Galaxy A21s Questions & Answers] thatha:
Does it work for stock rom Pamela ?
[Samsung Galaxy A21s Questions & Answers] PamelaGirl:
After flashing the super.img.lz4 tar file the device reboots a couple of times and ends up in TWRP recovery.

Still working on it
[Samsung Galaxy A21s Questions & Answers] thatha:
Just wipe data in recovery
[Samsung Galaxy A21s Questions & Answers] PamelaGirl:
Hello Everyone,

Thanks for the tip thatha, by wiping the data the phone booted up into the stock rom. I lost root and I lost the TWRP recovery.

All the data on my internal storage was encrypted.

The data on my external SD card looked normal.

When putting the device into Download mode it failed to install the Recovery file. Upon turning the phone off, and back on I get the Samsung startup screen with small red letters at the top of the screen saying:

Only Official released binaries are allowed to be flashed

Than the device immediately turns off.

Looks like I am jacked up at the moment
[Samsung Galaxy A21s Questions & Answers] thatha:
I don't know why but the red letters you said above are often seen on locked bootloader phone

---------- Post added at 08:15 AM ---------- Previous post was at 08:12 AM ----------

Now you boot to system, go to setting, developer options to see if OEM unlock is enabled or not. If not, enable it and try again
[Samsung Galaxy A21s Questions & Answers] PamelaGirl:
At the moment I cannot boot completely into the system. When I turn the phone on I get the message about only using official binaries. Afterwards the phone shuts off.
[Samsung Galaxy A21s Questions & Answers] PamelaGirl:
Hmmm...

When I did boot into the system after doing a data wipe in TWRP, should I have checked at that point to see if OEM was available and unlocked? Followed by installing TWRP, and later SuperSU.

I was not expecting to losing root and recovery, or the bootloop after flashing the super.img.tar.

Looks like I have to start the process all over from the beginning starting with installing the stock firmware.
[Samsung Galaxy A21s Questions & Answers] thatha:
How is it going on Pamela ?
[Samsung Galaxy A21s Questions & Answers] PamelaGirl:
How is it going on you say?

I have to press the power button to turn it on, at that point it displays the Samsung startup image with red text message at the top of the screen and immediately turns off.

If the phone is connected to a the computers USB than it’s an endless bootloop of what I mentioned above.
[Samsung Galaxy A21s Questions & Answers] thatha:
Have you flashed stock rom and try again ? Somebody advises us to do like this:

1. Try adb remount. If it succeeds, go to step 2.

2. flash multidisabler.zip

3. Format data

4. Flash magisk
[Samsung Galaxy A21s Questions & Answers] PamelaGirl:
I have not done anything since my last few postings.

Would I be doing steps 1 thru 4 all via adb?

Where can I find this multidisabler.zip?

As long as I have very clear instructions I can give it try.

Thanks

[Samsung Galaxy A21s Questions & Answers] PamelaGirl:
Thanks for the files.

Which one of these two I flash first?
[Samsung Galaxy A21s Questions & Answers] thatha:
New recovery that is patched to flash magisk
[Samsung Galaxy A21s Questions & Answers] PamelaGirl:
The instructions are starting to get a bit fuzzy. If I am to flash this "New Recovery" which I just did, it failed in Odin.

Am I restart the entire process all over and when the time comes use this "New Recovery" instead of the previous one?

Thanks

---------- Post added at 03:55 PM ---------- Previous post was at 03:18 PM ----------

Walk me thru this good people.

1. The device is back on bone stock Samsung Rom.

2. I set the date back in time and later connected to my network to get the OEM unlock to appear.

3. Flashed the new Recovery from thatha, and the device is now in a boot loop.

???

4. From within TWRP I have encrypted files so looks like I needed to "Format Data"

How do I get out of this boot loop?

Thanks
[Samsung Galaxy A21s Questions & Answers] PamelaGirl:
Hello Everyone,

Here is the latest update.

I was able to start the process all over, installed the super.image. tar, afterwards the device booted. I checked to see if the OEM was available after changing the date. When I did a reboot I got the message about only using Samsung official binaries. That was the end of the road as I see I must install the SuperSU before the device completely boots up.

Tried it all once again, got the super.image.tar installed.

adb Pushed the SuperSU.zip to the device and successful installed it in TWRP. Did a reboot and I am once again in a bootloop.

What am I missing?

Thanks

RECOVERY BETA 2

https://www.mediafire.com/file/7dd2x2vjze6cdon/TWRP-3.4.0-A21s-Beta-2.tar/file
[Samsung Galaxy A21s Questions & Answers] PamelaGirl:
Thank you thatha for the RECOVERY BETA 2.

Got it flashed and still the same boot loop as before.

I installed your recovery.

flashed MultiDisabler.zip

flashed Magisk.zip

wipe cache/dalvik

No errors, so I restart the system and the boot loop happens all over again. :(

What am I missing?

Thanks
[Samsung Galaxy A21s Questions & Answers] thatha:
Try format data
[Samsung Galaxy A21s Questions & Answers] PamelaGirl:
I did a format already.

In which order are you suggesting I do another format?

---------- Post added at 04:42 AM ---------- Previous post was at 03:45 AM ----------

UPDATE

The only way I was able to bootup was to flash Wer99's boot file.

I have no root although I flashed the SuperSU.zip.

I flashed Magisk.zip and after booting up it is not installed.

I should be outside enjoying fresh air...
[Samsung Galaxy A21s Questions & Answers] Wer99:
Pamela, you need to flash entire stock rom (AP) and unlock oem again. No need, I saw you can boot now* I tested this new_recovery and the BETA 2 (thanks), but it does not work (boot loop as well), only the old is working. And I flashed the 'Multidisabler', but the TWRP Recovery reverts/restores to the stock recovery every time I reboot.

Wiped my phone and 'got the stock rom rooted', but can't use super su app with it, only adb shell.

Guide:

1. Extract the supersu.zip.

2. Flash and boot the old recovery from Thatha

3. Go to "Mount", Disable MTP, and mount System.

4. Connect phone to PC and use this codes on adb:

adb shell mount -o rw,remount /system_root

adb push "...Extracted_Supersu_Folder\arm64\su" /system_root/system/bin/su

adb shell chmod 0755 /system_root/system/bin/su

Just reboot (adb shell reboot), enable adb debug and use this codes:

adb shell

su

Now you can use root commands using adb shell su, but no super su app.

The supersu.zip does not work because the root */* partition is at /system_root/, but supersu.zip script uses the root */...* path, so it extract the files to the wrong path, even changing the path to /system_root/... it does not work. So we need another way.
[Samsung Galaxy A21s Questions & Answers] thatha:
This can be fixed by just deleting recovery-from-boot.p from /system
[Samsung Galaxy A21s Questions & Answers] PamelaGirl:
Welcome back! :)

Thanks for the recent post with new instructions. Before moving forward I see that thatha has responded to your post. I will wait to see if there are any newer instructions.

Did I mention the days of rooting your device within minutes! Those are good ol days of owning older Samsung and HTC devices. These days its like pulling teeth.

Thanks
[Samsung Galaxy A21s Questions & Answers] PamelaGirl:
I am now on step #4 but the command is confusing.

If my extracted folder name is SuperSU2 which command is correct?

*adb push SuperSU2\*arm64*\su" /system_root/system/bin/su*

adb push "SuperSU2\*arm64*\su" /system_root/system/bin/su

adb push SuperSU2\*arm64*\su /system_root/system/bin/su

I am doing this on a PC and not sure exactly when to add these symbols:

*

"

Thanks
[Samsung Galaxy A21s Questions & Answers] Wer99:
Thanks I will give it a try.

Thanks. Yeah I thought it too, rooted several old phones within minutes just flashing TWRP and SuperSU. But today it took weeks, months or even years and if you do something wrong like when flashing wrong file, you lost your phone. Miss these days

Without asterisks everything is correct!

adb push "....SuperSU2\arm64\su" /system_root/system/bin/su

And use this code to change the permissions and owner:

adb shell chown 2000 /system_root/system/bin/su

adb shell chmod 0755 /system_root/system/bin/su

Update*: Made some tests and I confirm the stock rom is not suitable for rooting, because if you delete any file like an app or modifying the build.prop from the system, product or vendor... the phone will keep rebooting to the recovery every time, and if you wipe your data it reverts all your changes.

It just works with the GSI.

So resuming we need a system less root like Magisk. SuperSU is not recommended if you are going to edit the system or other partitions. Samsung...
[Samsung Galaxy A21s Questions & Answers] PamelaGirl:
Hello President Wer99,

Hoping your good!

Thanks for the response and the update on the ROM. I will now stop trying to get it to work after reading your comments. I will return to using your rooted Android 10 or 11 Rom.

If there is anything I can do to help test please let me know.

This seems to be a theme with many of the Galaxy A series, hopefully we can find one of those Roms that is rooted and ready to go.

Thanks :)
[Samsung Galaxy A21s Questions & Answers] Wer99:
Thanks Pamela :), the only way is Magisk root. Samsung does not like people messing it's files.

If any help just call.

[Touch Diamond, MDA Compact IV General] Wolfblood:
Today I've think more what can we do on Diamond. Then I think maybe we can add function key + shake to do more. Like:

1) Hold Down the Vol Down Key + shake horizontal = Play Next Music/SMS/Email/Photo (As user config)

2) Hold Down the Vol Up Key + shake horizontal = Play Previous Music/SMS/Email/Photo (As user config)

3) Hold Down the Action Key [The Round Button] + shake to Right = Move the TouchFLO3D Tab to Next Right Tap

4) Hold Down the Action Key [The Round Button] + shake to Left = Move the TouchFLO3D Tab to Next Left Tap

5) Hold Down the End Key + shake = Close all application

6) Hold Down the Phone Key + shake = Open the Contacts List

7) Hold Down the Back Key [←] + shake = Switch to Next Running application

8) Hold Down the Home Key + shake = Open your favorite application

9) Hold Down the Power Key + shake = Turn the LCD in WHITE and MAX the Backlight, So Diamond become a supper flashlight!

10) When not press any key + Rotation = Auto-Rotation just like GSen

11) When not press any key + move to front / back = Scroll up / Scroll down

See the Diamond can do a lot of things and iPhone can go back to home ;)

Maybe if can open those setting for user then they can custom the action what they need will be best for all people ^o^

Did anyone will interest on this? :)

[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] TalynOne:
According to this the Fire 8 HD Plus (2020) has the Mali-G52 MC1 GPU:

https://www.gsmarena.com/amazon_fire_hd_8_plus_(2020)-10246.php

From what I can tell this GPU should support hardware 10bit HEVC decoding but MX Player Pro and XPlayer both force themselves to software (choppy) when playing those files. Non 10bit HEVC seem to work fine.

Am I missing something, shouldn't this work?

Edit: This also indicates it should support Main10 1080p Level 4.1 @ 30 fps (which are my test files): https://developer.amazon.com/docs/fire-tablets/ft-device-specifications-firehd-models.html

You can check the codecs using AIDA64 to support 10bit HEVC or not.

Get AIDA64 from Google Play: https://play.google.com/store/apps/details?id=com.finalwire.aida64
[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] TalynOne:
Doesn't help, I doubled checked of course it lists HEVC, which I already verified, but that doesn't tell me if it supports 10bit HEVC. I mean obviously it doesn't since the players are forced in software mode I'm just asking why that is if the GPU seems capable.

Edit: I also checked AIDA64 on my phone which does play 10bit HEVC hardware accelerated and in the codecs list it just lists HEVC just like the 2020 Fire 8, there's no separate codec entry for 10bit HEVC in the AIDA64 list.

[Samsung Galaxy Tab S5e Questions & Answers] Matthius:
Hi all, just picked up a Tab S5E today - love the screen, built quality etc. What I don't love is the Wi-Fi performance. I'm left very confused.

I installed Android 10 right out the box and did a clean reset - after which my link speed in Wi-Fi settings shows 86 mbps throughput. For reference, my other phones (Oneplus 5 - 3 years old and Oneplus 8 Pro both show 866mbps receive and transmit speed).

When right next to the router I get a max of about 150mbps, with an average of 80mbps on Speed Tests - This is the case whether holding the tablet or not. When about 5 metres away through a wall this goes down to 45-55 Average, in comparison both phones show around 280-330 average.

When right next to the router with my other phones I get my networks full download which is 550mbps.

I understood before purchasing that if holding the tablet in the bottom left corner when in horizontal position (camera on the left) you are likely to lose signal - potentially mitigated with using a case. However, by wrapping my hands round the left antenna, on average - the speed increases to around 150-170 - odd...

When attempting to put pressure on the antennas from both ends and firmly wrapping my hands around the tablet, I do not see any network connectivity issues relating to dropouts and the WiFi bars remain on 5.

Honestly not got a clue what's happening here, either who have decently fast connections don't big this up online, or this is just a weird hardware fault with my unit.

Pretty disappointed. If anyone has any advice / screenshots of their speed results higher than this - I would greatly appreciate this, in which case I will definitely pursue a replacement device. I can't accept that in 2020 a device cannot achieve full 5.8ghz WiFi speeds when directly next to the router.
