Force fastboot? about sunxi-tools HOT 1 OPEN

Sorry for hijacking this really old thread, but i have the same problem. I have an Allwinner A33 based Smartbook S9Q9 (buil.prop displayed Astar_h7 before i killed this device...) tablet and i tried to flash a twrp recovery image. Now it always boots into this broken recovery (same issue: no nand and no touchscreen support).

I've tested everything, but the only device i can manipulate is my sdcard. I can boot my tablet into fel mode (with a sd card with fel-sdboot.sunxi flashed), but it doesn't respond to the sunxi-fel tool. Sunxi-fel always reports error -7 timeout (or something similar). Another problem is: there is no key combo for anything. You can't do anything, except boot it to recovery with the power button. Available buttons:

• Power on/off
• Back (it's a hardware key which can be pressed to boot to recovery)
• Volume +/- (no function while booting as far as i know)
• Reset button (in a small hole on the back of the device; (re-)starts the device instantly after releasing it)

There is and was no key combo to boot to fastboot. And the adb-command adb reboot bootloader doesn't work in twrp (i don't know why, but it just do a reboot to recovery).

Did you find a way to enter the fastboot mode again? Or does anybody else have a solution for this problem? I could provide more info like the downloaded build.prop, but i don't know if this is really necessary... And i have a backup (taken with dd) of the boot partition and the recovery partition. The main problem is, twrp doesn't see the nand devices.

Thanks in advise!
