If someone could help me, I would really appreciate it. So I am pretty sure that most of you are aware of error 29. It is either the software issue or higher chances the hardware issue, which is the battery. I know that I have to replace a new battery to fix it, but is there any other alternative to fix it? My friend asked me to help me update his phone, and now I brick it and it is stuck at recovery loop after the error 29. I am responsible for his phone and I hope someone here could find me another alternative. Like maybe downgrading or something? Please help me, thanks
