I have been testing ROMs on my SD card using _that's method from here as well as the built in ROM2SD install from the CROMI-X installer.

Everything was working great using CM10.2 until a few days ago when my TF700 became unresponsive after 5-10 minutes whenever I was running on the SD card mounted ROM. (It had been working fine for about a week of steady use). When it becomes unresponsive, it doesn't register any screen touches nor do any hardware keys work. The only way to recover is with a hard reset (holding the power button for a while even though pressing once has no effect). Decided to see if it was something related to CM10.2 so I reformatted the SD card and installed CROMI-X to the SD card using the CROMI-X installer... used it for a little bit and got the same problem.
I'm back to using the internal ROM and have no issues.

Has anyone else experienced this? Could it be a problem with the SD card itself (I'm using gparted to format and the card appears to function normally in other devices...)? I don't think it's a kernel issue as I'm using _that-v7 both internally and on the SD ROM (either through the CROMI-X installer or with the modified rom2sd2.zip from _that's dual boot thread).

Anyways, any advice or theories would be appreciated. I'd post in the original dual-boot thread but as a serial lurker/flasher I don't have enough posts to participate in the dev thread.

I could have written your post....
I had EXACTLY the same setup, progression and result.
No idea for a solution though.... But doesn't it feel good not to be alone?

You'll need to provide a logcat for a proper diagnosis otherwise we are guessing

But my guess will be your sdcard is not up to the task. What type of card is it?

Maybe. The microSD interface in the TF700 is known to be unreliable, at least in combination with certain cards. It was even worse with old ICS kernels.

What utility are you using to partition and or format the sdcard??

I have what everybody else has: Scandisk Ultra class 10 formatted with Gparted.

I think I have the last installation still on the card. I'll give it a shot and try to capture a logcat, but that could be a looooooong logcat - if I remember correctly both CM and CROMi-X ran fine for a few days and then froze without warning. Not much fun using the tablet with a computer attached to it

I'm also using a 32GB SanDisk ultra UHS Class 1 (the red and grey one) formatted with gparted.

As for the logcat, I haven't been able to get my tablet working over adb since I moved to windows 8.1 but I will be messing around with that today so hopefully I'll have something later.

adb works fine in Windows 8.1. Use these drivers here:

Ok, got adb up and running. The full logcat is attached. I used the most verbose logging and the last responsive thing I was able to do was go into settings and attempt to keep wifi on in the low power settings (this occurs at 11:12:34.489 in the log). The tablet obviously saves this setting however the screen fails to update or register input after this point and actually continues to highlight the check box for that setting option as if I was continually touching it. I let the tablet run for a while to see if it was just laggy, but it failed to respond for over ten minutes... Anyways, let me know what you think and I'll be happy to test any theories.

(as a side note, you'll probably notice my wifi continually disconnecting and reconnecting, but my tablet has done that since I purchased it so it's probably unrelated).

I haven't been able to reproduce the freeze yet. Ran the tablet on rom2sd for more than an hour with all kinds of apps, Netflix, Quadrant etc - works like a charm.
I did format the ext4 partitions before installing rom2sd (yet again). Maybe I finally got it right?

Possibly but like that said we've had this issue with some cards since data2sd days. If it does happen again, grab a logcat and post it up. I bet it will report file system errors.

Will have a proper look later, but on first glance your tab seems to have real difficulties staying connected to your router.
