My phone started to turn off at 15% battery after the latest update (10.2.1). Today it showed "unknown error" and wasn't able to read its sim card so I removed the battery to try to reposition the micro sim. After that the phone didn't boot at all. I tried plugging the charger in, holding the power button for a long time but no red light, nothing. At some point it did boot but powered down after the load, booted again and showed around 60% of battery. Sim card was still not found so I removed the battery again but this time it stayed dead. Is it possible that the battery is gone or my entire device is dead?

Impossible to diagnose with the information so far provided. Please try this sequence...note that, throughout the entire 4h15m process, your BB must remain directly connected to a known-good wall charger (not PC USB, not a cradle):
This has been known to "kick start" some BBs.
It is also possible that your battery or BB has experienced a problem...to test, this sequence is needed:
The results of this will indicate if it's your BB or your battery that has the problem. Note carefully please that "new" and "know good" are not necessarily the same things. While rare, a "new" battery certainly could be defective. Rather, the simplest (and least costly, btw) method to conduct this test is to find someone with an identical BB who has no issues...trade batteries and see what happens.
Good luck and let us know!
