Sorry if the question was already answered, tried the search but got on all sorts of threads nothing to do with twrp.
My OnePlus9Pro doesn't have SD but it does have a USB. So I tried to use USB storage for backup, but it's impossible in TWRP to mount USB. It's always 0Mb and cannot be used for anything.
Backup to internal storage looks like a bad move; how to restore any partitions when the file isn't on the internal storage anymore? (Yes, I know I can copy it to PC and later maybe copy back to internal) but it's also a problem that storage isn't backupped (maybe because storage is the destination?)
So the question: How can I mount USB OTG devices in TWRP when the normal mounting doesn't work?
Can you share the stock boot.img if it's for OP9 please? My phone is on the latest A12 OTA, and I tried getting root access but now my boot always opens fastboot. I'm trying to return to stock boot, but OP has A11 manual download only.Just chiming in for anyone looking for info on A12 compatibility: It doesn't work, don't attempt to install it. This one will boot, however does not work when attempting to decrypt data and trying to "Install Current TWRP" causes the system to soft lock in EDL mode.. Fortunately I had the stock boot.img to restore to.
I had the same issue. I ended up downloading A11 and using this guide to manually flash all the partitions: https://www.droidwin.com/unbrick-oneplus-9-pro-fastboot-commands/ This unbricked my phone. And I'm now staying at A11 until TWRP supports A12.
Thanks, will give this a shot!I had the same issue. I ended up downloading A11 and using this guide to manually flash all the partitions: https://www.droidwin.com/unbrick-oneplus-9-pro-fastboot-commands/ This unbricked my phone. And I'm now staying at A11 until TWRP supports A12.
which custom kernel did you flash. I'm guessing it was arter which means you need to flash dtbo.img, vendor boot.img, and stock boot.img for phone to boot. If you don't have these imgs, just flash your rom again.I made a mistake I think while installing this. So my phone was rooted and I installed a custom kernel. I followed the installation instructions and my phone booted just fine. I then wanted root back so I did "fastboot flash boot <magisk.patched.img>". I didn't do 'fastboot boot' because I was under the assumption that this would work fine, however it doesn't. My phone now just keeps booting, it shows the oneplus logo with those spinning white dots around it. I'm on oxygenos 11.
I've tried to reflash TWRP which gives the same result and when I try to flash my stock boot.img, it won't boot at all. Any clues what went wrong and how I could resolve this? My guess is that I need a boot.img which is modified for TWRP and I don't have that one on my computer?
Thanks in advance, and merry christmas
When adb says no devices or unauthorized, ckeck your adb key in a hidden /.adb folder in your User folder. Sometimes the authentication gets revoked and device is not recognised in adb.
Pretty sure I've found the issue,When adb says no devices or unauthorized, ckeck your adb key in a hidden /.adb folder in your User folder. Sometimes the authentication gets revoked and device is not recognised in adb.
If that's your issue:
Delete adb.key from <YourUsername>/.adb folder.
Turn off Usb Debugging.
Disconnect your phone
Turn On Usb Debugging
Connect your phone.
You should now get a dialog asking for authorization again.
You probably will have to do this again after disconnecting your phone for a long while.
TWRP has bug with mtp not functioning. The given solution was to disable/enable usb Debugging and enable/disable "mtp enabled" in Mount menu. That did not work for me.
What i think worked was this:
I plugged my phone in booted system ( or you can try fastboot) then after device is recognised by windows, go to
device manager > your phone's driver update menu > choose driver and install the standard windows mtp driver. Reboot to recovery and see if it connects.
I think that's worked for me when i tried installing this rom and found myself stuck with no way to sideload it. Spend all night on it before succeeding and tried lots of things so not sure it this works 100%. Hppe it helps.
the instructions say fastboot boot twrp.img, NOT fastboot flashSo far i have read onlyvup to page 8. But i noticed a lot of people having problems with fastboot (me included). I think fastboot flashes to inactive slot without saying so.
With slot a active, doing fastboot flash boot <filename>.img works fine (it goes to slot b) but rebooting anything (system, recovery, bootloader) ends up rebooting to fastboot mode in slot a (because of corrupted partitions).
I am now in twrp on slot b but can't sideload files to install ramdisk. Pc is not detecting device even with mtp enabled. Stuck at this point...
Edit: I was able to load the system on slot b. Transferred twrp img and installed ramdisk. Rooted and rebooted to system. On slot b.
Should i start again everything from the top to slot a (reboot slot a, fastboot twrp, install rom reroot)
