The problem, as I see it, is once you root your phone and put the custom recovery on it, CWM or TWRP, it overwrites your factory recovery. I tried using a 10k flashable zip I have to get my phone back to stock. BUT once I tried to get the OTA update to 10P, as another member here pointed out, My phone boot looped. So my question is, is there a way to remove the custom recovery and restore the stock recovery WITHOUT having to go through the PITA process of using flash tools? If there is a way it would save people countless hours fixing their phones just to get an update.
I know many of you don't see this as an issue because your whole point IS flashing new Roms. But from everything I have seen of this phone it's more trouble than it's worth. This phone is so very picky it's ridiculous. I just wnna get the damn 4.4 update, have it rooted to remove bloat, and call it a day. But to answer the OP question, you always have the option of buying a battery station online and charging your battery that way.
