- Lots of error messages when booting into CWM recovery ("E:Can't mount /sdcard" for example)
- If I attempt to boot normally, I get stuck on the Lenovo logo screen.
- Randomly I'll boot into CWM recovery and get its logo on the screen, and a line of text, but no menus.
- Other times I'll attempt to boot into CWM recovery, and just get a blank screen
So last night I used nvflash to put a new CWM recovery into partition 6: after which I was able to boot into CWM with no errors. (Yay) However, when I tried to reinstall CynogenMod (whose zip file was sitting on my external sd card), it hung during the installation. I rebooted anyway; this time it got as far as the CyanogenMod spinning logo and hung there. I went to bed, and seven hours later it was still spinning away.
Then I rebooted into CWM (without errors) and managed to install CM ROM this time also with no errors. However, again I can't boot. I get as far as the Lenovo logo, and if I boot into CWM recovery I have all the mount errors again.
Along the way I've erased the cache; done a factory reset, etc.
So: nvflash, new CWM recovery (but still errors), reinstalled CM ROM, but can't boot into it.
Any suggestions? Has this machine packed it in - is its hardware faulty in some way? Or is there something I could try which I haven't already?
Thanks folks - I think I've reached the limits of my fixing ability, and would be very gratefiul of some advice.
