I was trying to flash Pixel Experience 12 on my oneplus 7 when I faced a weird issue that i never faced before...when i put my phone in fastboot mode..PC recognizes my phone in 'fastboot devices' command..but returns empty when in ' adb devices'..which means it detects the fastboot but not adb..as a result im unable to sideload through adb....

Just use a pendrive to flash anything,if adb is not working .

How can I flash a rom using a pendrive??

I have installed roms before and this was not an issue...i just had my SSD replaced and windows reinstalled..I have installed the drivers, disabled driver signing enforcement, installed Qualcomm usb drivers etc.... fastboot recognizes but adb doesn't...quite the opposite of what most people face..also msm tool works..only ADB doesn not...
Also..adb works when the phone is booted..adb doesn't work only in fastboot

If you are using windows11, temporarily disable the w.defender and try again ..

Hello, i have a OnePlus 7 pro and i once unlocked it's bootloader due to that the widevine level fell from L1 to L3, then used msm tool to restore the phone and lock the bootloader but the widevine level is still L3, I tried many msm tools and factory reset but it didn't fix it even oos12.1 update didn't fixed it. I think my device's persist.img has something to do with.

Is there any fix for it ? Or do I go to OnePlus for this issue ?

This problem only exists in Android 10 when you update your device via ota to oxygen os 11 you will get your widevine level L1 by itself and it also L1 for Oxygen Os 12.1
It may not show to your device because you must have messed up some partition when tried to flash custom roms or anything else

It works for me try it

Right now i m on Android 10 and i am on L3

Hello, in the process of getting some repairs done on my phone I had to reset it to factory settings, erasing all my data. As I hadn't rooted it or unlocked the bootloader I was a little limited on recovery options and ended up making 2 adb backups using this guide.

Now I cannot seem to restore the backups - that's what I get for using severely out of date methods I suppose, I've used this opportunity to install twrp for future backup and recovery - using the adb restore <backup> command. It simply proceeds as expected for 5-10 minutes, before wrapping up and displaying a "Restoration Ended" message without anything having actually been restored.

I simply lack the knowledge to even diagnose what's going wrong.

If there's no way to properly restore the backup I'd hope to at least be able to manually extract and copy over my regular data (pictures, files, etc.). I've attempted to extracted the files from one of my backups using this, but cannot seem to find any regular files, just apps and their data. There's just a fraction of the ~10GB backup to be found in the .tar archive using 7zip, WinRar spits out an error that the .tar is corrupted. I suspect using Windows is not helping me here.

Any help or advice would be much appreciated.

Hello, I tried to root my One plus 7 pro via Magisk using this guide and must have messed something up. my phone is now stuck in fastboot menu and wont boot to OS, even choosing to boot to recovery mode boots back to fastboot.

Hello, I tried to root my One plus 7 pro via Magisk using this guide and must have messed something up. my phone is now stuck in fastboot menu and wont boot to OS, even choosing to boot to recovery mode boots back to fastboot.

So what if you can't acess recovery
-Just download twrp from official twrp website
-if you are on Android 11 then use twrp for Android 11 and if you are on Android 12 then use twrp for Android 12

-now go to fastboot and connect to pc
-type this command to boot the respective twrp whichever but make sure to copy twrp files on your pc adb folder then type this cmd

fastboot boot twrpfilename.img


This above command will boot your device into twrp recovery and from there you can just do whatever you want

Lets just say you have messeed up your device into bootloop by flashing magisk

Then you can just uninstall magisk from twrp recovery

Just download magisk uninstaller.zip and copy it to a pendrive
Then just install that zip from twrp then reboot

Now things will be normal again i guess!

My OP7 with OOS12 has this three-dot menu (top right corner in screenshot), my friend with the same build number doesn't have it. (With this you can set that you swipe from the bottom to come back instead of having to swipe from the side.)

Someone told me that I have to set this in the initial setup for having this menu, but I missed it.

Are there some adb commands for activating it? Do someone know how to get the menu afterwards?

Thanks for your help!

I don't think so ,you can just reset your device without formatting internal storage, after that you will get whatever was missing.

Yes I don't have root or unlocked bootloader, I wanted to downgrade so I can afterwards unlock the bootloader, root, twrp and a new ROM

You can use downgrade ota to downgrade your device to Android 11 then you can easily unlock bootloader

Or either you can use msm tool to flash Android 10 on your device then update it to Android 11 then unlock it but for this 2nd method you need pc.
