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. I flashed four different stock ROMs formatted userdata + cache successfully im recovery. Anyone have an idea how to solve the problem?

Did userdata flash successfully on any of the other roms?

I can't say about custom roms. Could be due to a locked bootloader
Is yours the EU or non-EU variant? How many different firmware did you download because I see 7 at the official website

1. Try power off the phone for 5 minutes then retry powering on
2. Try unlock bootloader using https://www.hovatek.com/forum/thread-32287.html . Let's see how that goes
