Ok, so they screwed up abl/bootloader/fastboot
Use the new recovery that I just PM'ed you.
I've figured out the bugs in recovery (the init service).
So my recovery now does autoupdate and stock recovery.
Code:
adb reboot edl
edl /lqcm2290.bin
edl /w /precovery_a recmod
edl /w /precovery_b recmod
edl /z
adb reboot recovery
So, you get a white screen (as before).
You could "start autoupdate" but you don't want to right now.
Type "start recovery".
You get the stock recovery.
Normally on a device without buttons you can pull/insert the USB cable to increment selection.
Unfortunately, since I own the USB that is not going to work.
You have to open/close the cover.
If you don't have a cover, use a magnet on the bottom edge of the screen.
The power button is select.
