Although I had Safe Strap, SU and etc. installed on my rooted HDX 7", I panicked when my firewall failed to block the 18.104.22.168 update and cut the power off in mid update. Unfortunate reflex that led to a soft brick. Although I now can get into Fastboot no problem (I can't access the ADB commands though), I have tried to flash recoveries, boot images and so on. I can erase data (I'd call myself an expert at this part of the rooting process) and arrange file system layouts but then can't get past this error:
FAIL: flashing not allowed for locked hw.
Anyone know how to, maybe change permissions on the hardware or whatnot to get the device to let me write to the system partition? I'm flashing from a iMac btw.
I mean the Christmas colors of the text as far as what worked and what didn't are fun to look at, but the actual loading of the Kindle OS might provide more long term visual excitement. Thanks and love all y'all's insights into navigating the treacherous waters of root access and tweaking the twerkinator in these here twandroids.
EDIT: I can use the ./adb commands but I was having trouble before with the period-less version. Was still getting no device to show up when I query adb but got this through fastboot:
fastboot -i 0x1949 devices -l
(serial number) fast boot usb:FA130000
Redaction is mine ...
