Ok, so an update on my second phone, just in case someone find this thread in the future:

I changed a bunch of components, but no luck, then I reballed the PMIC, still no luck. I put away the phone, and when i came back some days later, I changed R27, R77, R419 and R424 even though I did not see ANY damage to these components (at this point I had already set my mind on an A4 reball). Guess what? After this the voltage lines drops down to zero as they are supposed to

I am glad that I didn't reball the A4, this saved me half a day!

Anyways, after this the phone hanged in DFU, but no big deal. I measured only 0.9V on the PP1V2_SDRAM line, so I changed R76, after this U7 and then the phone was back to life. Excellent!

Big thanks to you Matthias! Hit me up for a beer if you ever visit Denmark

Cheers.
