No, not fixed. Worked fine for a few days then the problem came back. Just tried a non-stock ROM (Omega) and same thing. Trying a CM-based ROM now (ParanoidAndroid), but not too hopeful.

Still don't understand why it works for hours/days, then suddenly stops. Rebooting it fixes it the first few times, then that stops working as well (and I get baseband unknown at this point). Flashing a new ROM always fixes it, for a few hours/days anyway.

Sounds like a hardware issue, possibly nand memory becoming corrupt hence why it works for a while on a fresh install.

Any workarounds you can suggest? Just had the problem happen again on cyanogenmod, so that didn't fix it.

Try reading the freezing thread in general forum, see if the memory test tool will compete after a full wipe and fresh install of a stock firmware.

Other than that only a new motherboard, as the emmc chip is damaged.
