Whats phone condtition? Software cannot load emi from preloader.

KrzychuG · 07-12-2022, 15:05

I wiped preloader partition so i won't have to use testpoint each time, but overall phone was working fine.

Screenshot below is with preloader partition restored back, now it reads EMI from phone, but Pandora still fails to connect fully.

Last screenshot with original preloader and phone turning on?

KrzychuG · 07-12-2022, 15:22

That's the picture in my previous post, yes.

OK, so it was a hardware issue after all. One of the capacitors under the eMCP was slightly cracked, most likely during cutting EMI shield. It was causing a short, possibly interfering with RAM communication.

After solving this, the phone can be read correct via bootrom mode using testpoint.
