Hello guys, I have a problem with my Oneplus 8 Pro IN2023. the proximity sensor, light sensor, screen rotation etc. do not work. I have tried to install different versions of oxygenOS and each has the same problem. when trying to return to android 10, a crashdump appears, which prevents it from starting. from the information i found there may be a problem with the persist.img folder. could someone please help me with this problem and share the file or suggest another solution?

Hi all,
So I managed to successfully root and dump various bits of firmware etc over the past few weeks and generally had no issues(apart from the LED front panel lights not working(did at first), which is the main reason I was trying to rectify) - I have flashed from USB using a .bin also dumped preloader and rom etc via a scatter file using SP Tools after finding a rom entitled 8277L in the filenames, this worked perfectly(but still without the LEDS's) - Link to bought device(a cheap chinese one) - https://www.ebay.co.uk/itm/Single-O...e=STRK:MEBIDX:IT&_trksid=p2060353.m2749.l2649
Main issue: Now I have bricked it - I selected the format all part in SP-Tools thinking it would allow me to flash from fresh to stop the stock and TWRP recovery from timing out(I successfully ported TWRP over, but after about 30-40 seconds it was rebooting the device, bizarre!) - When the head unit is powered on it turns on the display but that is all, just a light black screen. I've tried recovering again via USB and SP tools but I think I'm almost out of luck. SP Tools doesn't read from the device or detect it, and yes I have the correct drivers installed under Windows. No screen swiped or button presses help in getting into any bootloader or update mode.
I am really hoping, anyone could help identify the UART pins on the board - yes I've now taken it all apart - in the hope I can flash a bootloader image which I guess is what is now wrong and has been erased??
I've really been digging into this and researching on Russian websites and getting lot's of interesting information including from XDA thankfully, but not this issue. I have included some pretty much hi res images, some are dark but I have redone some, everything is readable but I've googled and googled for model/part/serial numbers etc and have had no results that helped to indentify where I could potentially find the UART connection.
If anyone has the same unit or similar it would be great to share the knowledge so perhaps we can help bring the info together and help other debrick this device if there are any!
Many thanks, for anyone who cares take a look!

Same problem
I am facing the exact same issue.. Have you figured out any solution to your problem mate? Any help would be appreciated.
Hey everyone,
My accelerometer and gyroscope direction are wrong. When I turn on automatic rotation in Android it goes to landscape when I hold my phone in portrait mode and vice versa.
The problems started after I used the Xiaomi Flash Tool to return to stock. I used the clean all and lock option. I used TWRP to flash persist.img to get rid of the device search error in MIUI. After this my accelerometer started to be 90 degrees inverted.
The problem is fixed by flashing the persist.img (if you didn't make a backup of your persist partition) from the Telegram group for the Mi Mix 3 5G: https://t.me/mimix3_5G
I've got same problem with my phone.
Can you provide instruction how to fix it ?
One day my proximity sensor randomly stopped working, I fixed it once using the incoming calls dialer method but then it stopped again. After that my light sensor stopped working. I thought it was my persist partition that was corrupted but I tried flashing the fastboot from and even tried flashing the persist IMG extracted from the fastboot rom but it didn't fix it. I don't know if the hardware itself is broken or if it is a software issue. All my other sensors work. Someone, please help me fix it. I can't go to the service centre to repair it as it was purchased in India and now I'm in the UK
Hi everyone,
I have the all classic fingerprint sensor not working after display got changed problem and even an MDM tool flash / EDL mode did not fix it.
If I calibrate it from the debug menu it works until the next restart
Does anyone have the corresponding and in an OK state persist.img? (I have the European version)
Thank you!
side info:
To calibrate it I type in the dialer: "*#899#", then "After Sales Calibration" and 6776.
Guys, after trying an update of firmware, display went blank(led light still on). Now, it is working, but no image on screen.
Tried my old firmware, could not see on screen the process of updating, but how usb was flashing and screen light was going on and off, I presume it was updating.
Anyway, where to find a display config file for this platform? I tried to update couple of display config files from internet, but non of them is working. Maybe someone know for this msm8953 platform how to revive the image on screen and to make it work. Many thanks in advance
Try a full reset from recovery mode. Look this video (maybe help you). Recovery mode
