iPhone 12 Pro Max Restarting And Freezing Problem (Userspace Watchdog Prs0-Springboard) Panic Repair

Hello Everyone.
In today's video, we have an iPhone 12 Pro Max that came with restarting/freezing problem.
Now based on the device's history, the device was never opened and never repaired yet.
Now when restarting the iPhone, to make it easier to do diagnostics and not to solder everything, go to Settings-Privacy-Analytics and improvements-Analytics data-find the record of the last reboot and look for keywords in it. Mostly in the logs there are abbreviations such as prs (pressure), mic (microphone), ALS (Ambient Light Sensor),... Records of lines and elements from diagrams are also common.
I will be making full diagnostics based on the full panic and the analyzer program for reading the panics (including the site)
P.S: Please try to watch the video till the end so I can understand the diagnostics and the repair.

nice share brad

[@repairyouriphone1696]

I didn't understand do you did a swap for rf beord our not

[@hattafuzairie]

Hi sir, right now I'm struggling infront of my workstation with this same issues for my customer's iPhone 12 Pro Max missing sensor(s); Prs0. I have done changed 2-3 charging flex, swap upper layer, flash on 3utools, testing on jig tester but the problem still same. May I know swap the bottom layer solved the problem? Like yours in this video. This only I haven't done.

[@AntoineKiriaky10]

Please watch the video again because I think you didn’t watch it completely till the end, Prs0 it’s something to do with the barometer sensor, which is located on the charging flex connector

[@hattafuzairie]

@@AntoineKiriaky10 I watched completely till the end and I know the barometer sensor is located at charging flex which is my first comment above I changed 2-3 charging flex but it doesn’t solve the Prs0. The question here, is the RF layer (bottom board) is related to barometer Prs0 issue? Only this I haven’t try.

Hello, i've used a battery programmer on a 12 pro max battery and now it gives an error in panic logs " missing sensors prs0 /nservice:backboard" and the phone reboots every 3 minutes i removed the flex that was coded for the battery but the issue persists... what can the problem be ?

[@AntoineKiriaky10]
