[Thinkpad Tablet General] hume_xda:
My M10 was working, sitting happily in its charging dock when suddenly it started crash-looping, with a "dm-verity corruption" error. The Lenovo Rescue utility (which, infuriatingly, demands logging in to use) wasn't able to repair it. On the Windows box, you can hear USB connecting, and then *immediately* disconnecting, again and again and again.

I was able to get into fastboot long enough to try flashing TWRP 3.7, but after that the tablet will NOT boot into fastboot, recovery, or anything else, and it doesn't matter what combination of volume/power I use.

The crash loop goes like this: Vibrate, Lenovo logo with an "Orange state" error for ~15 seconds, black screen, vibrate, back to start.

When connecting to a Linux box (to try to use the SP Flash Tool), I see the USB connect/disconnects like so:

So this occurs on both the Windows and Linux machines, with different USB cables tried.

At this point I don't care what firmware I end up on, whether stock or otherwise. There's no data to rescue on it and the device is too old to bother bringing to a repair center (2G RAM, yuck). But if I can rescue it I'd like to try.

But is this thing megabricked?
