Unable to flash custom recovery

Hi,
I have the Find 7 with the new display panel.
I wanted to flash the latest version of TWRP but failed. I do not know what I did wrong.
I can use adb and fastboot without any problem. When trying to flash recovery, it says there that the flash was successful but when I reboot to recovery, TWRP was not installed and the original Oppo recovery is still there.
The bootloader is unlocked. And I tried relocking and unlocking again but to no avail. Whenever I use the command "fastboot oem unlock", nothing happens to the phone.
I am currently on spectrum. I want to try other roms such as the lite COS 2.15 and also maxwen roms since that only those supports the new panel.
I am also trying to get root for my phone and it is impossible without custom recovery.
Thanks for any help.

I had poop loads of issues with getting custom recovery on my Find 7a. Eventually I used these instructions:
http://community.oppo.com/my/forum.php?mod=viewthread&tid=996
They work. Don't know if it's the versions of ADB or Fastboot or something.
Give it a go

I will give it a go when I get back. Thanks!

This is what a forumer from the official forum said and it works:
After you had successfully flash recovery via fastboot, you MUST NOT reboot the device. AFAIK, if you reboot the device it will restore the recovery back to stock oppo recovery.
So instead, you need to immediately press vol down & power button on the fastboot screen. Keep holding the button until you see the TWRP recovery screen. Hope that helps. Cheers!""

Unlocking bootloader erases data?

Mine wouldn't flash recovery. It said successful but I still had oppo recovery 1.2 and it only worked when I found the latest official twrp over version 3. after flashing, I disconnected usb and then held down power button to shut the phone down. It then was able to boot to twrp ok.
I used the latest one.

3.2.6 OTA failed to install? "SOLVED"

Hi.
- I flashed TWRP using ADP, flashed root to change fonts but used Stock OOS 3.2.4
Now i sold device.=, to buy black one or iPhone
- I done data reset in TWRP to unroot, after reboot SU App was gone.
- I flashed stock recovery via ADB
- I left the bootloader unlocked, i was not sure of comand, plus in case of mess up, i could fix it.
New user has no idea as well, he says now when he installs OTA 3.2.6 it fails to install.
What i am missing? how can i fix this?
Help will be much appreciated, thanks in advance.
EDIT: SOLVED
When i locked bootloader, it took me to bootloap, and when i try to sideload new OOS3.2.4 it gave ever, cannot read file.
- I flashed new official TWRP again.
- I flashed stock 3.2.4 with TWRP
- Set up OS
- Flashed stock recovery, in fastboot by doing USB debugging on
- Locked bootloader by "fastboot bootloader oem lock" right after stock recovery
- Set up OS 3.2.4 again, at this moment 3.2.6 fail to down over the air
- I downloaded stock 3.2.6 incremental update, successfully downloaded and install.
Now phone seem to be at stock. I bought it back from to save him from inconvenience, as he was scared as the phone was failing to install update initially.

Also interested on this, same thing happened with me and a friend, modded his phone, he didnt want it modded anymore, flashed a clean stock OOS, flashed stock recovery, and error on install of 3.2.6 OTA, if anyone have any idea how to recover the ability to OTA, appreciated.

When i sideload oos.zip which is 3.2.4, it says cannot read zip.
When i relock bootlaoder, it goes into bootloap, i go back to fastboot and unlock bootloader, it boots back into old stock OOS 3.2.4. This rom still has my changed fonts, which i had when i had root and TWRP.

I know there was a firmware change with 3.2.6, so if you flashed the 3.2.6 recovery with OOs 3.2.4, this could possibly be your issue.
Boot into Twrp, don't need to flash it. Clean flash 3.2.6, reboot. Try relocking bootloader see if you still get boot loops.

Possible to restore recovery and re-lock bootloader without data lost

So I brought oneplus 3t for my father from china so it running hydrogen OS but now we moved back to Australia it would more sensible to change to google services for apps download and updates so i flashed Oxygen OS something stable but I was wondering how should re lock boot loader and maybe flash to stock recovery (Optional) to have boot up message and maybe encryption enabled.

You need to have usb debugging enabled in your phone and adb tools installed in your pc before you do this.
For locking bootloader :
Connect the phone to computer,
Restart the phone in bootloader mode
Open command prompt window
Check connection by typing fastboot devices . You should see your device listed
Type fastboot oem lock
Reboot once the process completes. Be aware this will wipe your phone and ALL data will be lost.
It is advisable to keep boot loader unlocked.
For stock recovery :
Download stock recovery image from the forum
Save it in the same folder where your adb is installed in windows. The file name should be recovery.img
Reboot into bootloader mode
Open command prompt and
Type fastboot flash recovery recovery.img
Stock recovery to be installed before you lock bootloader

a cautionary warning regarding the above reply to you, don't' relock the bootloader while you're on a custom recovery and/or kernel, and also while you have changes to the system (installed any mods or deleted any files form system folder)
so in theory it's possible,
1- you need to sideload a full stock rom (download from oneplus website) it's better to be stable not beta (you should have adb drivers installed and stock recovery, sideload will insure you have stock everything)
2- after you successfully sideloaded a full stock rom and make a full boot to system, you can follow the above re-lock instructions.

Currently it running oxygen OS from their website like full rom.zip, i know when you flash new recovery you will factory wipe the phone which i don't really wants. Are they like patch to remove boot up warning? because last time i check there wasn't one.

A new recovery does not wipe your phone.
There is no patch to remove the boot warning. The only way is to lock boot loader <- this will wipe your phone and data.
If your phone runs well, it is better you keep it as it is. Why fix something that's not broken ?

OP7T ROM Installing Partition Error

After trying to install a custom ROM (PixelExperience for OnePlus 7T [hotdogb]) via fastboot, the installation flashing ended with errors with "no such partition" for odm, product and system I tried everything to get out of the fastboot screen loop. After finding a bat file with IMG files which got me on the Android 11 Beta 1. build (still no WiFi)
What can I do to fix the partition error to get on the Pixel Experience ROM or even get back to the stable build - I did try MSM but it isn't listing the phone even after pressing ENUM.
Please help...
Context (can skip): The latest stable build OOS for my 7T had issues with the microphone not working and so I decided to do a factory reset which resulted in having a clean install but now, WiFi doesn't connect for some reason. After trying some fixes I decided to install a custom ROM.

U need to flash stock recovery (fastboot flash recovery recovery.img) as twrp prevents fastbootD entry. Then type fastboot reboot fastboot to enter fastbootD. Then flash your rom. Personally, I just flash roms via Chinese twrp or 3.5.10 twrp

that was my process for the first try - entered fastbootD for the flashing process which ended with the mentioned partition error and the fastboot loop. I realised that TWRP version I got from TOOL ALL IN ONE wasn't going to work as it couldn't access data no matter what.

No twrp can decrypt oos or a11 custom roms data. Chinese twrp can access data only on a10 custom roms if u remove screen lock before booting into twrp for backup

What do you reckon I try this time then?

Question TWRP, Full OOS etc. Stuck without OS... please HELP

So I wanted to switch from OOS 11 to 13.
I was unl;ocked, rooted with magisk installed.
Updated to c47 and flashed magisk. all good.
Then flashed TWRP and tried flashing the full OOS c64 I downloaded.
The flashing failed and now I have no OS since I wiped before flashing as recommended.
At the past with previous devices I just flashed TWRP, flashed the ROM, reflashed TWRP and was done with it.
How can I recover my phone now? All of the data is backed up (contacts, apps, photos) so it's not a big deal if I lose all my data.
Currently I'm at TWRP
PLEASE HELP ME

Also when trying to activate sideload, TWRP is stuck on 'starting ADB sideload feature' and nothing happens, adb devices command doesn't recognize the phone and I have a red warning 'unable to decrypt FBE device'

Just use MSM TOOL and never unlock bootloader.

Not sure but I think the problem was installing twrp, as far as I know it does not support installation, just start without installing like, (Fastboot boot twrp.img)
Why didn't you follow all the updates without inventing fashion?
Just download the complete package of the update and does the manual update, does not restart the phone, go in magisk, click install and mark the third option, which is to install after full Ota.

I don't think TWRP even support flashing OOS.

@N1ldo cause I wanted Android 13 and the OTA failed to update from C47 to C61.
Also I thought that my past experience with flashing the Oneplus 6 will still be relevant, which obviously isn't apparently...
Gonna try to follow the MSM guide.
But for the future, assuming I will succeed in restoring via MSM, what should I do in order to gain root?
1. MSM
2. re-unlock the bootloaded
3. Flash magisk via fastboot
That's it? did I get this right?

nope, you boot twrp-3.7.0-12.1 via fastboot (fastboot boot twrp.img) and there you can install magisk. if normal installation doesn't work, try using sideload. if you plan on flashing the twrp installer zip, do it before flashing magisk as it patches your current boot image.

great. and I can do it regardless of the oos I'm running right? I wouldn't ask that question under normal circumstances but after today, better safe than sorry

should work as I described. if you want to be 101% safe, just boot the twrp, but if I remember correctly, the installer should work on oos 13. if you want, you can extract the payload.bin of your current oos so you have the stock boot.img and vendor_boot.img in case anything goes wrong. you can find the exact description here.

Thanks, And one last question, if I'll unlock the bootloader now that I've installed all of the updates up to android 13, it will erase all the data but not the updates, right?

Never mind, it works, after the updates I unlocked the bootloader, patched the boot image, booted from it and installed magisk. I now have root.
Thanks all for helping me out!
