[Eee Pad Transformer Q&A, Help & Troubleshooting] turbohobbit:
Righto. Before we go any further, jsut to say I am a relatively experienced rooter of Android handsets. Not tabs, granted, but handsets. Last night I rooted my TF and flashed Megatron and recommended kernel, no problem. I've had no problem taking nandroid backups or restoring as I've done that several times today, all with expected results.

Then I opened ROM Manager and allowed the app to update, I guess updating CWM too.

I then fiddled with SetCPU overclocking the CPU. This caused the tab to stutter a bit. Then freeze. Anyway, I hard rebooted and went into recovery to try and flash the backup I took about an hour ago. Now, CWM looks different (I guess this is where ROM Manager updated). I flashed the backup which seemed to go ok, but then when the TF rebooted I got an Android message saying that encryption hadn't worked properly, and that I would need to do a full (factory) reset. I hit ok and let it do it's think. The TF rebooted, but went direct into Recovery.

I tried wiping everything using Factory Reset, and wiping Dalvik, etc, but every time I tried I got a message saying "E: Can't mount /sdcard/" and then it reverted back to the main menu structure. Even when I choose "Install zip from sdcard" > "choose zip from sdcard" I just get a message up saying "E: Can't mount /sdcard/" and that's all she wrote. I think a) ROM Manager may have caused this and b) it's royally wrecked.

I did find teh following in a TF guide regarding cold booting:

-Quote-

11. Now do a Cold Boot (aka Hard Reset). This cleans system caches, but does not delete any user data.

Unplug the power cord and shut the unit off. Press and hold the VOL DOWN and then POWER button at the same time for at least 10-12 seconds until after the start-up screen appears and is joined by some small print at the top of the screen, then let them both go. If the TF booted the way it always does, you have not accomplished the task, try again until you have seen the 2 icons in the screen.

After a few seconds you should see a couple of icons in the middle of the screen called "Wipe Data" and "Android". The right "Android" will have a green highlight fading in and out. Wait a few more seconds until the term "Cold Booting Linux" appears in the list near the top of the screens and let it reboot. If you own a keyboard dock be sure you do this with the dock connected.

This process applies to all TF models, however, if your Prime or tf300 is locked up, there is a reset available using the hole just below the microSD slot, this is NOT the same as a hard reset.

12. Finally, restore your photos, docs etc & reinstall your apps from the backups, one group at a time & cold boot between each group that you restore. (Unless you are resetting because of system instability. In which case, read the next section, first.)

-Unquote-

I tried doing this but the TF froze at the point where the unit says "Cold-booting Linux". I left it for a good 30 minutes but no joy...

The other issue I have is that even when I attach my TF to my PC the PC doesn't recignise the unit. It knows I'm trying to attach something but it doesn't know what. Therefore I don't think I can flash anything like a new CWM version or kernel if the PC doesn't know where or what to flash to...?

I'd love to hear anyone's thoughts on this one...

Thanks in advance!
