I just wanted to say a massive thanks to Deak and Mick for helping me un-brick a 3S the other night on the IRC channel.
A duff memory card installed a corrupt firmware, and left the tab trying to install firmware each time it was turned on, then crashing to a black screen. Then requiring a full battery/power disconnect to restart.
Much rushed entering of 1021 before it hit the crash eventually got a busybox shell running.
After about 90 mins (I think it was), we got some semblance of a firmware working, and we were able to copy the working copy from sdcarda7 to sdcarda6. Which was enough to get the sd card mounted, and copy the working modded firmware accross.
Turns out it was actually an earlier modded firmware (42.xxxx), but worked well enough for me to run the Execute installer from within the tab itself (45.xxxx).
Now it is all running smoothly, thanks to much trial and error, and talking a linux noob through some basic commands.
So, again, thanks for the help. Hopefully the transcript/tutorial will be available to help others soon?
Also worth noting, connecting tx-tx and rx-rx on my cheap USB-TTL adapter didn't work. You must connect tx-rx and rx-tx. If you are getting garbage on screen, then (however amazing your soldering skills are) check your connections. I cleaned, fluxed the pads, tinned and trimmed the wires, did a very neat job of the soldering, and still had to re-do it all.
