- Kindle Fire 2 (2nd gen, also second-hand) tablet: stock, rooted, that worked fine with the tool by bin4ry.
- Rebooted after that, verified root was working, adb and fastboot perfectly fine (sidenote: linux user, no shonky Windows drivers at fault here)
- My ultimate goal is to get CM on this device, so, started after this to follow the instructions in this thread regarding getting the second bootloader on the tablet.
- Realised I need a factory cable, ordered, delivered, works but not all the time, I'm not sure if it's a dodgy cable or not but did get into fastboot.
- Got new bootloader installed, saw Kindle Fire logo in blue. Proceeded to boot the stock rom after this and use adb push to put the CM 11 zip and the gapps zip files on /sdcard.
- adb shell, su, reboot recovery, intending to boot into TWRP to flash new rom
- Tablet reboots, but is now stuck with the stock boot logo (orange) and then a black screen with a white triangle and exclamation mark on it. I haven't seen any references to this particular delight.
- Fastboot cable does not, no matter how I fiddle with it, put the tablet in fastboot mode. Holding down the power button for five minutes did nothing.
I've read that if it turns on, it can probably be recovered, but I don't know what to do from here. Can anyone render assistance?
