    So I randomly did a manual reset on my z10 and when it booted up, a red battery pops up with an exclamation and then the address "www.bberror.com/bb10-0020" shows up?

    Apparently my battery was defective when that pops up (via BlackBerry website support page). I didn't believe it, so I did another reset and poof! My z10 starts again! What the flip? Maybe the battery was loose or something...but my z10 on "God Mode" can't go out like that so easily....

    Anyone experience it before? The ones with a 4500 mah battery?

    My Z10 burped like that once, with the stock battery. It was after I had charged it up using the PlayBook charger, for some strange reason. Except restarting it didn't change anything -- it just thought that battery was dead. Did a full charge on its own charger and all was well after that. Little gremlins in there, no doubt.

    Decided to turn on my spare Z10 I've had in my drawer for eight months. I wanted to test the latest 10.3.2.500 leak. When I plugged the phone in it gave the same bb10-0020 you mentioned. I checked online and it says "The BlackBerry 10 smartphone had detected a non-functional or bad battery." This might explain the random reboots the phone had (which it why I stopped using it). The battery is the original one it came with.

    I then plugged in the phone again and it started up normally. After the loading screen the phone will stay on for about a minute or so and then reboot. Guess I'll turn it off for now and get another battery.

    Got the same problem on a Q10. Tried to reload the OS but nothing happened. Ordered a new battery from an oficial BlackBerry store and after installing it the problems were still there. Same message. Tried to reload the OS several times in different PCs but nothing so far. Dunno what to do as every place I searched on the web informed the BB error 00-20 was a batery issue. I think I should send it to maintenance but Im afarid the Q10 is dead.

    Hi, I had this error this morning after leaving my Z10 in the drawer for a couple of months. Just left it plugged into the charger for a few minutes and then it rebooted and started fine. I think that it's a "hyper" low battery situation.

    Got this error last night. The two variables:

    1. Installed BBM update from BlackBerry World (updates for anything are few and far between)

    2. I had tandem charged two batteries with the external battery pack chargers (forget what they're actually called) the day before.

    I'm not sure which batteries I had been using. I have four. Two had been charged with the the little plastic chargers connected in tandem. Not sure which two I tried in the phone. Several batteries produced the error. In any case, it wasn't looking good, but I was persistent and did numerous restarts till it finally "took." The Q10 held overnight and all day today, even started up okay after a battery change this afternoon. Hopefully it's all set. Keeping my fingers crossed.

    Has anyone experienced this with a Passport? I changed the battery but haven't been able to turn it on since then. Stupid non-removable batteries. There's no good reason to not have a removable battery IMO.
