realme c21, can't unlock the bootloader - Android Q&A, Help & Troubleshooting

hi, i have a realme c21 , but it has a problem, after 1 year of realme UI 2 without updates (because i never got the realme UI 3) i got tired of the usual interface, so i would like to install a rom, the pixel experience, but the problem is that the bootloader does not unlock, because when I restart it from ADB sideload in fastboot, the phone restarts in the normal way, without going to fasboot, and for a second you see a message that seems to me to be: emiei does not match
reboot_bootloader_faild. i searched for a long time and i found nothing, even trying to downgrade from android 11 to android 10 it doesn't work, because when i install the OTA update at an installation point it says "FAILD TO INSTALL OTA UPDATE", the '' realme unlock doesn't work, because it says that my devices are not supported, could anyone help me?

bump, i also was looking for any rooting ways but it seems sketchy or just impossible, i've seen some previous Realme devices getting successful root, but no luck with RMX3472.

You need to use fastboot, a/b partitions typically don't have recovery image, and realme 9pro is using a/b partition

Maybe in the future for android 15. The device is also expected to receive official Realme ui 5.0 Android 14. If you want to install custom rom like Pixel Experience you can try to install gsi rom. There is a tutorial how to install gsi rom in russian forum 4pda.

Help needed to root Viewsonic VSD243 non-GMS device

Hi all,
I'm hoping one the XDA geniuses can help with a challenge I have!
I have a Viewsonic VSD243 I bought second hand to give to my kids but didn't realize it's a non-GMS device and therefore doesn't support playstore. Most of the apps the kids want need playstore so have been looking for a way to get playstore working without luck. Now I know why it was so cheap!
The bootloader is locked and I haven't been able to get to the bootloader to unlock as there are no physical volume buttons on the device and abd reboot bootloader just restarts the device...fastboot is not finding a device no matter what I try. I've been attempting various other workarounds for weeks with no luck (e.g. methods used for Huawei devices using apps like chat partner, ) but not had any luck
Please could someone recommend a method(s) to unlock the bootloader / root the device given the above (especially with the restriction of not having physical volume keys)? Ideally I'd like to create a dual boot on the device, one with existing ROM and one with custom (e.g. via Magisk) but can't get to root :-(
Your help would be really appreciated

I successfully unlocked and rooted a VSD231 with KingoRoot.apk just say no to all the junk it tries to put on it. I am going from memory a long time ago.
thank you for responding and good to know you managed with a viewsonic device. I'll give it a go as don't have many other options...
I spoke to Viewsonic and was told the only way to get playstore was to jailbreak the device and put on an alternate ROM...when I asked how to unlock the bootloader to do it they said they couldn't / wouldn't tell me :-( !!
When I talked to them years ago, they were very surprised that I unlocked and rooted my VSD231.

Please help. I'm dumb and flashed Android 13 from DUI settings on Android 11 without unlocking bootloader.

So now on restart it tells me system is corrupt and need to decorrupt and I have to press power button in 5 second phone will shut off. I press the power button and it loads normal. Everything works but it's way slower lagging and stuff. I tried to log in recovery but I up until just now pressed a bunch of random buttons for into recovery mode. It word never make it to recover mode the little Android man wild pup up and say no system command. Anyway made it to recovery mode and wiped the partitions and rebooted and still popped up system corrupted. I also have done a factory reset to no avail. Oh yeah I forgot to state that the upload of android 13 from 11 made it almost 3/4 of the download before stopping. So it never finished and I'm still running that same Android 11 just with I'm guessing corrupted files from boatloader not being unlocked. I mean it's a 60$ phone from Walmart but it's all I have right now. I'm sure a couple people have been there. Anyway I know someone knows what I should do. Just say screw it and don't mess with it since it still loadimg morally and I can get online and use apps. Or is it a crash waiting to happen?? Should I download factory rom from somewhere and root, then unlock boatloader, flash ROM and restart. And if someone could tell me how is the best way to flash or get the corrupted files off before I I flash the new one?? Or will the news one fix the crashed files. Please just a dummy needing help.

Lenovo J606L custom ROM

Hello there.
I have a lenovo j606l tablet, it works fine but its OS is too slow and very bad.
I wnat to put a custom rom to get better fluency and experience but I hadnt can find any sinlge custom rom for this exacttly model (J606L).
I found the next thread but is to J607F and I tried for all options of these thread but none of them works.
TWRP neither works on J606L. I found the unofficial twrp 3.4.2 but when I try to flash or boot recovery the tablet stuck on boot lenovo logo and is needed run windows lenovo rescue tool to restore the tablet.
I had tried many other things to flash custom rom but all of them have been a lost time ( orange fox, adb sideload install, arm64 ab images, fastboot flash, fastboot boot).
I am really tired.
Please someone know any custom rom release for this tablet (J606L) or any way to flash custom rom to this tablet and that it works?
thank you for supportme.
