Hi berndlb,
First, let me just say thanks for writing all this up in a clear and easy to read way. As you mentioned, a lot of information on the web for this this is fragmented or out of date. In fact, I didn't even know half the stuff I had read was outdated until I came across your thread.
So, I got all the way to issuing the 'fastboot reboot' command without any problems, but my device is not actually rebooting. Here's what I'm seeing in the fastboot command window:
Code:
C:\Minimal ADB and Fastboot>fastboot devices
[I][/I] fastboot
C:\Minimal ADB and Fastboot>fastboot -i 0x05B0 flash recovery twrp.blob
sending 'recovery' (0 KB)...
OKAY [ 0.060s]
writing 'recovery'...
OKAY [ 2.877s]
finished. total time: 2.939s
C:\Minimal ADB and Fastboot>fastboot reboot
rebooting...
finished. total time: 0.550s
But my device never actually reboots. It stays on the (bootloader?) screen with RCK / Android / Wipe Data. It appears to be stuck, as the RCK is no longer flashing and pressing down volume does not advance what is highlighted. If I restart the device by holding the power button and select RCK from the bootloader screen, I get the Android on his back.
I've tried this a few times and I've noticed that the RCK icon actually stops flashing after I issue this command:
> fastboot -i 0x05B0 flash recovery twrp.blob
If I try a 'fastboot reboot' without issuing the command above, my device will reboot. Also, if I try a 'fastboot devices' after the command above, the response I get is:
???????????? fastboot
I tried a couple TWRP blobs (2.6.3.1 and 2.6.3.2) thinking that may be the case, but received the same result.
Any ideas? I haven't been able to find anything on the web, partly because it's hard to construct an effective search string for this issue.
