When you have TWRP you have to install full zip, not simply the eval OTA zip

Flash the stock recovery.
Get stock recovery from downloads.oneplus.net

I cant seem to flash the stock recovery. The device is not visible in adb devices or fastboot devices. im facing the same issue.

If you are using TWRP 3.0.4-0 - try a hard boot...hold down the power button for 20s...wait 20s, power it back on.

easy solution. Boot into fastboot
download this tool.
https://forum.xda-developers.com/oneplus-3/development/toolkit-oneplus-3-toolkit-unlock-t3398799
if newest version isnt working, download an older version with older twrp
than unzip the tool and run the .bat file and install twrp.
Thats it

There are many posts on Nougat not working with official TWRP (based on 6.0 build). Try booting into stock recovery. performing a system settings reset, then booting into fastboot and run the adb command, <fastboot boot TWRP-3.0.2-1.28.img>. From there you can do virtually anything you need to do. I recommend at least using a modified version of TWRP (such as 1.28). This has been posted many times before, please try and do a search for the answers first, it will help tremendously. Thanks

i had the same problem on my rooted OP3 when i used TWRP 3.0.2-1 , it worked to flash the full 4.0.1 rom but failed for everything else, flashing latest verion of twrp fixed it for me

Got the same problem (unrooted phone + device state locked, cannot access recover, but can access fastboot) with an added "benefit", USB debugging mode was off before it all went crashing and burning.
How to access my phone via PC? (all the guides I've found assume I had USB debugging mode on before the phone got soft-bricked, but as a normal phone user who never installed anything custom, I've never figured it is A MUST BE ON function).
Or simpler question - what tool to use to turn on the USB debugging mode? (if that is at all possible?)

Noted that you solved your issue, but this post is about the new version of TWRP. Version 3.0.3 is available on twrp.me and it works with Nougat.

LG G4 H815 No TWRP Access

Hello members of XDA,
The issue I'm having is pretty rare and found few or non threads about it, so I will try to be the most precise possible.
Yesterday I decided to change the ROM of my LG G4 H815, I was previously on LineageOS, since LineageOS on H815 wasn't developped anymore. So I asked myself why not trying Android Oreo with CypherOS. Before any changes I was with the latest version of LineageOS for H815 and I had TWRP with the version 3.0.2.1. Bootloader was obviously unlocked.
So I starded to download all the required material to switch to CypherOS 5.3.1, while the download I've made a backup of my actual lineageOS installation on my internal storage. Once every thing was downloaded I tried to install CypherOS I had an error 7 in TWRP install box, so I was pretty worried, scouted XDA threads about the error but i was redirected to the solution where you modify the update binary with txt but still didnt worked. I've found a thread talking about updating firmware of the H815 ( https://forum.xda-developers.com/g4/development/v5-8-5-n7-1-2-resurrection-remix-t3704450) While panicking I've done a wipe of everything (dalvik, data,cache and system) .I applied thge firmware update but I also re-read the thread of CypherOS and figured that I needed a newer version of TWRP, installed it so. THen magically CypherOS installed without any issue.
After installing the Gapps (Arm64 8.1 Nano) I rebooted and the first weird thing appears, after seeing the LG screen while the boot I have another screen telling me that the bootloader has been locked and that i should visit g.co/ABH for more information, then CypherOS initialise, CypherOS worked like a charm. So I wanted to go to my TWRP and make a backup in case. I launched ADB and use the command adb reboot recovery, the phone restarted and had the following events : LG logo, warning message about the bootloader, LG logo again and then a black screen. However I was in recovery mode since adb found me with the command fastboot devices. I had no TWRP logo or anything linked to it. Few minutes later, I had the basic recovery mode where you move yourself with the volume buttons and select with power where the functions are pretty limited.
Then I rebooted the phone with adb (fastboot reboot), CypherOS still working perfectly. Thaught that it was the bootloader which back to scratch when he was blocked, I figured out that he was still unlocked, I used the command "fastboot getvar unlocked" through ADB. THen I thaught i had to install back TWRP, tried through the fastboot mode but I had an error
Code:
FAILED (remote: unkown command)
since i tried everything i could even in the basic recovery mode, the only working command in the recovery is "fastboot flash recovery twrp.img" but still does nothing.
I mean it's not that terrible since I can use my phone and i'm about to change phone in 2 months for a Oneplus but i would really like to be able to install magisk on the phone to grant root access and be able to use TWRP on it like I used to. By the way the backup of lineageOS has been deleted while performing unecessary wipes.

It's clearly written on the official website and in the official TWRP support thread for the g4 what you have to do when on Nougat bootloader and want to flash TWRP... and keeping it.

Yet, this still doesnt help me to solve my issue. Do you think there is a way to fix it or no ? If not, I'll just deal with it for the few months lasting.

Okay if it doesn't work for you you must do something wrong. It works 100%. If you really want help you should explain in detail exactly which steps you took as otherwise it's all just guessing what you're doing.

Indeed, I didn't followed the procedure exactly, didn't do the step after flashing TWRP (removing battery and boot manually to recovery). Well thank you, was my bad on that.
Should I do a clean new install of cypheros or should I keep it like that, what would be your advice ? Knowing that at the moment CypherOS works like a charm. I also plan to install Magisk on it to root it.

Moto Z2 Play [XT1710-09] won't even boot in recovery

So two days before Android Oreo update released (RETEU channel). I tried to flash Magisk cause i needed root access but then i realized that the Bootloader was locked and i unlocked it. Everything was ok until i tried to flash a custom recovery (TWRP) but after that everything was way too complicated. I flashed TWRP but everytime i was trying to restart my phone and get there it was replaced with the stock recovery. I tried to find something online and i did here in XDA. Everything was working and i said that is time to flash Magisk, i rebooted my phone in recovery mode and after that i flashed Magisk, but after that my ROM was destroyed and i didnt even had a backup (yes i know i should have done that, but i totally forgot about it). I said ok, the phone was released almost a year ago and there should be a Stock or Custom ROM online, i did find a couple of them but everytime i tried to flash them i was getting an error, i found the problem, my TWRP was a 32bit version and i changed that to a 64bit, but no other ROM except Lineage 15.1 was working. After flashing Lineage Os I found out that my fingerprint sensor wasn't working, my flashlight too and the camera was awful. I went back online and tried to find a stock ROM but i couldn't find anything, i tried a stock 7.1.1 and stock 8.0 but none of them was working. The last thing that i did was trying to flash it with ADB and after that my phone was working for 10 min until i got a security update that after the installation my phone didnt even boot again, i cant boot it, it isnt showing anything, no vibration, no sound, nothing Please help!

Question Revert back to Stock OOS

Hi Guys,
I hope every one is doing well. I have been on the latest Paranoid Android Sapphire Beta 1 build for the last few days. I have been liking the rom so far but I would need to go back to stock OOS for now. Aside from using MSM tool is there another way to flash back stock OOS zips via recovery? I tried sideloading via AOSPA's recovery but it failed (no worries, as I am still able to boot to AOSPA just fine).
Kind regards!

Many thanks! I was having issues downloading the stock firmware files needed for the MSM tool. I do have the downgrade zip and ota signed zip for my model, but extracting with payload dumper gives me only 7 image files so I think it's incomplete, and I would still need to download the full firmware files to be able to flash via fastboot.

If you try using fastboot to downgrade, you're very likely going to brick and have to use the MSM anyway.

I was able to flash to oos11 using twrp. Well, I was on crdroid and there are custom ROMs that require oos12 before It will work. So I went crdroid 8.6 to oos11 to oos 12 and then lineage 19

Well it was a ride for me lol. Took me a few hours to realize I can gain fastboot access via long pressing power button+volume up and volume down altogether. I was then able to reflash the modded magisk boot image to regain access to AOSPA.
The fun part came after trying to flash back to stock via MSM. First I figured out that instead of using the "vol up+vol- button approach then connect usb" way of trying to get MSM tool to connect to the EDL mode of the phone, an easier method is to use "ADB reboot edl" command.
Now as I previously used global stock OOS, I mistakenly used the MSM tool for the global region. However, this got me in a SHA-256 mismatch in the flashing process, causing a flash error which got me back to getting stuck at the bootloader again. Turns out the global MSM tool does not work for LE2120 model.
So at this point I had 2 options - either find a MSM tool that works, or try flashing back to stock via fastboot. The fastboot way would have worked but I ran into a problem - you have to flash to .img files partly via fastboot, then partly via fastbootd. And when on fastbootd my phone is not recognized by the PC (this is why trying to flash back AOSPA also failed, it can't continue the fastbootd part of the install as for some reason my pc loses connection with the phone on fastbootd).
My saving grace was I found out that for LE2120, the EU version of the MSM tool works. So long-story short I got back to stock OOS 12 again. It was a fun yet nerve wracking experience, and I learned a lot.
So the lesson of the story is, for anyone tinkering with this device, to learn the basics, from knowing your correct model number, knowing the proper button combinations to boot to fastboot/edl/recovery, knowing which tools to use, to knowing how to setup/troubleshoot your pc to ensure the phone communicates properly at every step!

[SOLVED] boot loop after i tried to fix broken root

I tried for like 3 hours to find a boot.img and i had root on my phone, but without wifi and sound.
a quick google search showed me that it was because i had a wrong version of the boot.img, afterwards i found another one and now after i have tried installing twrp, booting and flashing using adb (stock and modified versions of boot.img) but it just keeps bootlooping. in twrp i cant wipe, make a backup, see any files in /storage/ and i have no clue what to do next.

What model 7T do you have? HD1907? What was the rom that you were using before you installed TWRP on? OOS12 does not support TWRP. Custom rom A13 does not support TWRP. Only a few custom rom A12 and OOS11 support TWRP.

Idk but I'm just wondering if flashing the last working rom image (dirty flash)? That would eliminate TWRP(?) and eliminate Magisk(?) while hopefully keeping the device from being wiped possibly?
*** Hopefully someone could/would verify this before you attempt... ***

i was on android 11 but i cant remember the version, i have HD1903 (EU ver). i THINK i had the one from the oneplus website(https://service.oneplus.com/us/search/search-detail?id=2096229) but idk anymore

I JUST RANDOMLY TRIED BOOTING MY PHONE AGAIN AND IT WORKED imma check if everything works and will regardless still look at this thread bc it can prob break easily
nah wifi and sound still dont work, but im not in bootloop anymore

i cant find the file for my current version and it doesnt work if i try it with the only version that is android 11

and i cant turn my phone back on
and after i installed the drivers i had to restart my pc and now there is this thing at the bottom right:
testmode
windows 10 pro
...

i waited until my phone had no more battery charge and now im bootlooping again :/

nvm it just booted

im downgrading it now and i dont get the error "smth communication smth" in msmtool anymore
alr it worked my phone is wiped again but i can turn on wifi and sound
but how do i root my phone now? I have an Idea, im gonna write step by step what i think gets me a rooted phone please confirm if that would not break my phone ^^' (bootloader already unlocked)
1. enable usb debugging and allow my pc
2. download and install the latest magisk version from the github
3. download magisk patched boot.img for ver 11.0.5.1BA BUT since i cant find anything on the internet im gonna have to use the zip file from the unbrick tool thing (https://onepluscommunityserver.com/list/Unbrick_Tools/OnePlus_7T/EU_HD65BA/R/) and then patch the boot.img using magisk myself
4. then use platform tools and type following commands: "adb reboot fastboot", "fastboot flash boot {the patched boot image file}"
5. then use magisk to direct install the root thing

i just realisized the unbrick thing that i wanted to use instead of a boot.img doesnt have a boot.img in it... WHERE CAN I FIND A BOOT.IMG brooo androidfilehost.com doesnt have it the unbrick tool doesnt have it
omg i realized i could update my phone to 11.0.9.1 then download the same version from official website and use the dumper to get the boot.img **** meee

wait it sais its 11.0.9.1HD65 AA and not BA **** me

k nvm i just changed the site settings to germany and now its BA

i just went for it and now my phone is rooted thank you very much for your help i would've prob tried to revert back to stock for like 2 weeks and then cry that i cant root my phone thank you so much xd
