Hi,
I want to backup my Oneplus 3 using TWRP/ADB.
ADB has been freshly installed from PlatformTools and is running fine, if the phone is in regular (unrooted) OxygenOS (8.0.0)
After installing TWRP 3.3.1-0-oneplus3.img using fastboot, then directly booting into recovery, the device does not show up in "ADB devices -l".
1) What is the reason for the device not showing up?
2) Even though I booted directly into TWRP after installation OOS reflashes stock recovery. What did I miss?
Thanks for you input
M.

Ive been reviewing some of the threads on this forum for 2.3.3.0 and this doesn't look good. In my case I went ahead and downloaded Android 5.1.1 and transferred the zip file to the nexus (ADB Driver) as well as usb otg. I attempted to install the zip file but keep getting the message: "error flashing zip" (log is attached). After the first failed attempt I went ahead and removed then re-downloaded 5.1.1 again but still failed, Ive tried Android 4.1.2 but had the same result. Ive went to TWRPs site and attempted to perform a recovery using TWRP 2.8.7.0 but the recovery in TWRP 2.3.3.0 wont recognize any images. One last resort was to load from ADB SIDELOAD within TWRP 2.3.3.0 but still fails. Are there any other troubleshooting steps that could be performed?
Hi!
Try to flash any stock rom via NRT.
Heres what im getting when trying to communicate with the device: "ADB Device not found". Attached are the images of communication with the device while in TWRP 2.3.3.0 recovery mode, Is there a way to get NRT to recognize the device during the bootloader?
EDIT: I Found the FAQ, I will need to do some more research.

Hi!
Of course it is, just boot your tablet to fastboot mode, and choose in NRT Current status: Soft-Bricket/Bootloop.
If you really have a Nexus 7 (2012), you're using the wrong factory image (and you're in the wrong forum).

Kept trying with fastboot mode but ADB still wont recognize the device. When i boot in TWRP it does recognize the device just fine. Any other suggestions?

Hi, pepper55.
In recovery you can use ADB sideload
Simple ADB (not sideload) doesn't work without OS.
Use fastboot for the soft-bricked device.
Try to restore your tablet using stock google image, and "Flashing Instructions".
Hi all.
After OTA upgrade to android 6 of unlocked unrooted nexus 7 2013 WiFi i decided to unlock and install twrp.
I used adb and fastboot to flash version 2.8.7.
It went smooth but after reboot to recovery, twrp shell returns "can't mount *" for all partitions. And the device is bootlooping into this state (unless I boot into bootloader).
The worst part is that my pc wont recognise the tablet when connected. Adb devices returns an empty list. So i cant even flash stock recovery or do anything uing adb/fastboot.
HELP!!!!
[solved] falshed factory image manually using fastboot
It seems fastboot recognized the device while adb/pc couldn't.
I downloaded Android 6 factory image from google and flashed-all that.
Just updating in case some other noob who doesn't fully understand adb/fastboot relations.
Hi I tried to OTA on my D802. It downloaded the latest update file, rebooted to TWRP, then I had to manually instlal the update and since I did it it bootloops to TWRP.
So I wiped all data, system .. everything and via USB-OTG flashed clean OS and gapps. Anyway Im not able to boot to OS even I press BOOT TO SYSTEM in TWRP.
I updated TWRP to the latest 3.0.3-a (originally I had 3.0.2-1.
I cant boot to OS and my D802 is useless. anay help ???
thank you
Petr
Manually like fastboot? Are you sure you did not flash TWRP to boot instead of recovery?

My D802 downloaded new nightly build and rebooted to TWRP and nothing happened. So I install the new nightly manually in TWRP.
Since I did it it reboots only to TWRP.
Tried to wipe all in my phone including internal storage etc. and installed new fresh Lienage (tried more nightly)
I even tried to install it from fastboot and it boots only to TWRP itself even I use BOOT TO SYSTEM in TWRP.
i had no chance to flash TWRP instead of updated OS since there is only lineage-14.1-20170306-nightly-d802-signed.zip and open_gapps-arm-7.1-stock-20170308.zip on my flash (OTG)
update: It does not matter what ROM do I install to my D802, I get TWRP bootloop only ..
Solution
I know the solution of this problem just read carefully
You have to do it from the fastboot.
Google your device and learn how to enter into fastboot mode after switching off the phone via pressing combination of hardware keys.
Then Google and download the exact same following files for your phone model not others (wrong files will brick your phone). Following are the files :-
1 boot.img
2 droidboot.img
3 recovery.img
4 rom.zip
(All the above mentioned files should be the official files provided by the manufacturer company of the phone)
Now download the basic Windows or mac or Linux driver of your phone for the computer you have and install it in your computer, then restart your computer and also install the "minimal fastboot" in your computer and then connect your phone while phone is in fastboot mode, then copy all the above mentioned files in the folder where the minimal fastboot driver is installed.
Now go to that folder where minimal fastboot is installed in your computer and press shift key and while keep pressing the shift key right click the mouse and select "open command" here.
Note Google and learn the command how to check whether your device is connected to your computer via fastboot.
Then install all the mentioned files using fastboot commands.
Hurry you have your phone with official ROM and then if you want use the same technique you may have used earlier to unlock bootloader and root your device and installing the latest twrp.recovery and then lineageos.
Now your phone is unbricked and you have latest lineageos.
Also remember the ota update of lineageos is broken so don't install updates via updater app.
The safest method is to download the whole update package and put it into your phones internal/external/usb otg drive and install via custom recovery.
Be happy

Hello, I have a huuuuge problem.
Every time I try to flash TWRP through cmd, nothing happenes. I have all needed files, my phone is being recognized in adb devices, reboots on command, is on fastboot devices list, reboots on fastboot reboot command, but it totally do nothing when I use fastboot flash recovery twrp.img command. Maybe it's my drivers fault, because last time i uninstalled my device through Device Manager, somehow it worked and I flashed TWRP. But then I switched to MIUI and as expected TWRP was removed. And I cannot flash it, please help
Did you update to latest MIUI?
Yes, right now I'm on Global Stable.
Turn your pc into a new one then you will.
Why turn your PC into a new one? resetting?
Isn´t there another solution?
Removes old data such as adb,platformtool, twrp.then can do it.I've come across and solved this way Do not know why

Posted another tread:
I struggled a lot installing TWRP. I did not succeed flashing TWRP from my PC. My solution was:
Starting up TWRP: fastboot boot twrp.img / boot command only boot and does not flash.
Thereafter installed Magisk 17.1 from TWRP for rooting
Thereafter flashed TWRP / I tested flashing both by using Flashify and TWTP Manager and both worked.
Maybe by using Flashify I had to use an older version of TWRP. Think TWRP Manager let me install 3.2.3-0 direct without problems.
Hello. I recently unlocked the bootloader on my Nokia 6.1 phone and booted a modified TWRP installation, which I used to wipe my phone as recommended here:
https://www.howtogeek.com/348545/how-to-install-lineageos-on-android/ (Step 4)
Now I only have TWRP on partition A and Download Mode.
Question is: How do I transfer LineageOS or any Zip file to /sdcard?
TWRP's ADB Sideload fails after loading for some minutes.
Doing "adb sideload lineage.zip" or "adb push lineage.zip /sdcard" will display "Error: no devices found". I can't make adb work after booting into TWRP, but it also won't work when doing this via fastboot.
I am a bit lost here and would like it if someone could help me install LineageOS on my phone or at least clear this issue.
Once tried in windows 11 I faced same situation,
But in windows 10 worked out well (but I installed Lineage Os recovery)
