Hello,
I have a problem with the Teclast p20hd N6H7. The tablet had a problem with turning on. After unplugging the battery, it went into flash mode. When flashing the original software by ResearchDownload R25.20.3901, an error occurred while flashing UserData. After skip UserData, flash went to the end and the tablet started up but stuck in a bootloop on teclast logo. I tried other firmware from Tescals website, same problem. I can't upload via fastboot because the bootloader is locked. Anyone have an idea how to solve the problem?
enter recovery mode from Volume key and select factory reset (= format userdata + cache)
Its didn't help
did it work? you have flashed stock ROM and formatted userdata + cache successfully?
userdata partition is encrypted on first boot, for some devices initial boot takes up to 30 min. how long did you wait?

Didn't work. I flashed four different stock ROMs formatted userdata + cache successfully. I waited 4 hours.

Hi everyone!
I'm facing a weird problem: I installed Resurrection Remix again (7.1.1) (it was my main rom) and TWRP started asking for the encryption key (although it was a pattern). I entered into recovery and did a wipe as the system requested.
Then, I realized that the encryption problem went further and I tried
Code:
fastboot format userdata
After that, the bootloader is able to boot just the TWRP recovery.
Then I tried from this link https://forums.oneplus.net/threads/beta-8-encryption-help.479290/page-2:
Code:
fastboot format userdata
fastboot format cache
fastboot format system
fastboot erase recovery
fastboot erase boot
fastboot reboot
fastboot flash recovery <twrp28>
However, nothing changes.
I also tried to do all wipes, to format the data and system partition as EXT4, to reinstall RRemix 7.1.1 a lot of times, and, again, the system can just boot into recovery.
I saw a lot of user with the same problem, however, there is no solution for this problem yet.
OBS: the phone is booting successfully with the command:
Code:
fastboot boot boot.img
And then, after one manual reboot, the bootloader chooses the recovery again. The phone continues to boot into TWRP only.
The Encryption is gone, but I can only boot using this manual mode discovered by @Sompom

Could someone please help to fix this boot problem?
If there is any information than I can provide, please, let me know.
Thank you!!!

Now the phone always boot on TWRP which stuck on splash and sometimes it boot the rom but has encryption unseccessful. I do not have DL as there is TWRP as well with the same problem. I can boot to fastboot but the command : fastboot erase recovery alway get unknown command. I also tried flash the laf.img via fastboot but it doesn't work.

I was trying to install LineageOS 16.0 on my P20 Lite. I was following the official tutorial: https://wiki.lineageos.org/devices/anne/install
When I was trying to format the data partition, twrp never finished. I googled it and found the following thread: https://forum.xda-developers.com/oneplus-3t/help/stuck-formatting-twrp-t3586406
I rebooted my device to see if i could format it in ext4 (it was using f2fs by default)
But after rebooting, i couldn't get into the recovery ( stuck at twrp boot screen ).
I already tryied:
1) Reflash the twrp recovery
2) Flash the default recovery ( stuck at 'Your device is booting now' )
3) Boot into eRecovery to restore the device ( stuck at 'Your device is booting now' )
4) Format data partition from fastboot ( 'Command not allowed' )
4) Flash default system image ( Because it was on the thread i found )
5) Flash kernel image ( Don't know if this would change anything )
The only thing I can really do is boot into Fastboot.
Is there any way to restore my device?
Hope someone can help me

Have you changed the 'data' format to ext4?

I wasn't able to because fastboot wasn't allowed to and I can't boot into my recovery to do it.

it's all right, normally it is on each P20 lite device f2fs (including Custom ROMs). Have you tried Stock recovery from fastboot? ( You TWRP is installed over Recovery or over eRecovery?)

Yep I flashed the stock recovery multiple times but it's also stuck at the boot screen ( 'Your device is booting now'). I've waited for ~15 Minutes, but nothing happens.
Okay,
I was able to recover my phone by booting into fastboot and erasing the userdata partition. Then the info '(bootloader) success to erase cryypt info in oeminfo' popped, what surprised me. After that I was able to boot into eRecovery and recovery my phone!
I have unlocked my bootloader using official Asus tool, I then went on to flash TWRP 5.3.x.x. using fastboot and also formatted userdata and cache from fastboot itself to remove encryption. Recovery works fine.
I have tried flashing both these ROMs. [links below]
[ROM][OFFICIAL][11.0][X01AD] Arrow OS
[ROM][11][5.R] Project Sakura [2021/03/19][UNOFFICIAL]
I followed the instructions, formatted data using TWRP, wiped system, vendor, cache, data, dalvik.
I then flashed the ROM from TWRP itself, and I have also tried to install it through ADB sideloading. Then I wipe dalvik/cache.
Both instances, the installation happens fine but when I reboot phone gets stuck in fastboot mode. I resolve that by flashing 'vbmeta.img'.
Then phone starts booting but gets stuck in a loop bootloader-->ASUS logo-->"Powered by Android"-->bootloader
So basically, it does not boot into system.
I have even flashed stock A10 firmware from here Stock Vendor and Firmware images for Asus Max M2 but still no resolution.
I have also tried manually mounting system partition from TWRP, doesn't work.
Any help would be much appreciated.
Connect phone and PC via USB-cable and in Windows command prompt run this command sequence
Code:
fastboot devices
fastboot reboot
to take back phone to it's normal ANDROID mode.
