Could it be in DFU? Did you try to revive it with AC2?

Hi’ 2informaticos I flashed 01949 dump into the chip recovered from 00850. I do not think it could work with a dump from another type of board.

I am writing to you dear colleagues because I for a long time and search never found a solution on my macbook pro 2020 820-01949 intel issue which showed prohibitory sign no matter what I tried (Everything was tried with DFU and so on - everything:-) all values were normal on LB and it was a...

Thank you 2informaticos 🙏

Hello everyone. I have a special case (i think so:-) and I do not know if the post belongs here but i try: I have a macbook pro 820-00850 - logicboard is broken (screwdriver or projectile destroyed the logicboard) and the customer has valuable data stored on it which he will pay everything for...

by the way... which DCP do you have? I need a new one

I have the Peaktech 6070 which has been used for cellphone... But I see I need to upgrade. I have an old one which can power up so I will try that one and let you know:)

Hi. Did you manage to solve this problem? I have the same issue and it sucks!!

Hi again 2informatiocos and others. 4 volt and 5 amp.... goes to 0.300 amp but get only fairly hot under UL000. If I remove the RD810 I get 20 volt and stable 0.000 amp. I've searched for a similar problem here in forum and found this one - could it be the same issue - U8100 short? I will write...

Hello. I have a question for you:-). I have an 820-02020 A2338 MBP which takes 5 v. and 0.495 amp on one port and 20v and 0.120 on the other port. The machine had some liquid, but is not significantly damaged. It is shorted on pp3v3_s2 and pp3v3_s2_WLBT__ISNS and gets a bit hot seen on thermal...

Hi’.it is as 2informaticos says very important to use the right charger. I do not have much hair but almost lost the rest of it because of a similar issue as yours. After hours and hours I was told to try another charger (96 watt) and boom👌…. Problem solved (to be honest I still forget it)…...

How does it ready when you put it in DFU mode and choose recover? Do you hav a stable internet connection?

What are the values on the thb port?

All respekt for any solution you’ve discussed but as 2informaticos write there is/could be corrosion on traces resistors and even under BGA chips. It is a very corroded/infected logicboard and will have issues in future. In 9 out 10 of -2003F failures I solved with known good topcase. I do not...

Hi good people. I do not need help for this this time - but would like to share an experience with 820-01949 (A2251). I've got a mbp 2020 with clean/pure logicboard. Client said that it suddenly died - Took 5v and 0.250 amp in. One of the thunderbolt ports bootlooped every 2-3 seconds. I...

Hi’ I have an issue on th QP800. The enable pin on UP800 is 1,2 volt. But it keeps shutting down. I need to find a donor and then I will let you know. Thank you 2Informaticos for yiu Gold nuggets until now:-).

Thank you. I will do it right tomorrow. Thank you very much.

Yes… still a drop. Slow drop… but I can not see failures on the mentioned traces. But something/somewhere it drains for voltage on that line.

Finally… now it is image, but no backlight. Should I replace UP800.
