[Teclast X98 Air 3G] juan3211:
Hi, I have a M5C5 tablet with dual boot bios installed a week ago. I successed installing windows 10 and android. But today, the tablet only boots into SHELL.

I can get into DNX FASTBOOT mode, and I have tried to unbrick it with this method (I don't mind to loose dual boot, I want to unbrick it)

This is the CMD windows log:

D:\fastboot.exe devices
Baytrail00000726 fastboot

D:\fastboot.exe flash osloader efilinux.efi
sending 'osloader' (2463 KB)...
OKAY [ 0.115s]
writing 'osloader'...
OKAY [ 0.002s]
finished. total time: 0.122s

D:\fastboot.exe boot restore_bios_m5c5.img
downloading 'boot.img'...
OKAY [ 0.729s]
booting...
OKAY [ 0.000s]
finished. total time: 0.731s

After the first two commands, the tablet shows the same text:

Entering DNX mode.
Waiting for fastboot command...

But after the last command I get this text:

Entering DNX mode.
Waiting for fastboot command... EFILINUX [ 0.000428] ERROR [fs_init:226] No de
vices support filesystems
EFILINUX [ 0.001628] ERROR [efi_main:529] fs_init failed, DnX mode ?
EFILINUX [ 0.002756] ERROR [get_path:334] Couldn't find boot device handle

Does anybody what can I try ???

I have already enter BIOS and reset defaults. I have BIOS tPad 1.00 (it is the dual boot bios version), I can also enter DNX MODE, but I don't know what these messages mean.

I have also try to flash stock rom, and this is the log from Flash_Tool program:
