My beloved V10 is apparently dying
It isn't plugged into USB. I just replaced the battery with a fully charged one and got this again:
That's "910K B98" in the lower left for anyone that finds this thread from Googling.
Off to LG for repair soon

I'll really miss not using it for the next several weeks. I may have to wait for it to totally die before sending it off.
This might be similar to the dreaded bootloop problem?
Another symptom, the radio (data/sms) also stopped working for a few days. So intermittent problems as mentioned in a different thread.
