I can't reflash stock recovery

Hi, yestarday I flashed CM 14 with TWRP to try it, and today I have tried to return to stock rom & recovery but I can't do it. At the beginning I have tried to flash stock recovery that I have downloaded from op.net with fastboot and I couldn't do it and after I have tried to do the same process but this time flash it with TWRP and also this time I couldn't able to fix it. In fine I have installed the stock ROM via TWRP and I managed to install it but now the problem is that I still can not install the stock recovery and accordingly I can't install op3 update.
An another problem is that I have tried to re-lock OEM from fastboot and when I try to turn on the phone, is asks me a pin to enable it and I don't know that pin because I haven't set no one

No it isn't. Because I managed to put stock ROM into it via adb with push command and after I have installed it from twrp that works. My only problem is that i can't flash stock recovery.

i have the same issue. Tried many times but i'm getting a black screen after one plus logo for both stck recovery and unmodified twrp. only moidified twrp is working. please let me know if u find a way to resolve this.
thanks in advance

you can reboot in to stock recovery without any issues?? I think I should give it a try. And you are saying the bootloader is locked again ?

Great. Can I place the file in beta8 rom .zip file and flash it using adb ??

If this procedure doesn't you can download an older version of oxygen os and update it via ota. At the first attempt when you will try it will give you an error and at the second attempt It will download all the ROM again and it will reflash by itself

I suggest you to try at the beginning with the beta 7 because if that procedure not work for you, you can't downgrade to beta 7.

Thank you.
Will let you know if it worked.

I had that problem.
Solution as follows, worked everytime for me: (I have not tried this method with the newest beta 8)
1. Flash OOS 3.2.6 firmware in twrp.
2. Reboot to fastboot and flash official oxygen os recovery downloaded from the OnePlus website. (This is still the old version for some reason, thus why it won't work)
3. Side load community build with oxygen os recovery, this will flash the new firmware back and update the recovery to be community build compatible.
4. Before rebooting erase everything (factory restore)
5. Reboot to OOS, finish setting up.
6. Turn on advance reboot in developer settings.
7. Reboot to recovery via the reboot menu. First time boot into the recovery may take sometime, but it has always worked for me.
8. After everything looks good, go ahead and OEM lock in fastboot, recovery should work as usual this time and format your phone

OP did you find a solution to this?? Im on the same boat as you

OnePlus 3 broken? - Only booting in Recovery

Hello, I had some trouble after a CM Update. It was only possible to boot in FastBoot, now I'm a bit further and can go to Recovery and also install ROMs.
But I'm not able to boot to the system, everytime I reboot I get into recovery, does anyone has a hint for me? What to do in this case?
Right now I have this version of twrp installed: https://forum.xda-developers.com/devdb/project/dl/?id=21835
But with the officiall one from here: https://dl.twrp.me/oneplus3/twrp-3.0.2-1-oneplus3.img.html
I can still only go to fastboot and not to recovery, I just have no idea why...
Thanks for help allready

Download the official recovery here:

What is the exact output if you do
Code:
fastboot flash recovery recovery_OBT7.img
OOS4 is the stable release. I would strongly recommend it over cm right now. It's actually quite polished.
You can download the official full zip here:

Flash TWRP 3.0.2-22 (download available in other questions. Wait a bit will link it.
Edit: https://forum.xda-developers.com/attachment.php?attachmentid=3971072&d=1481920669 )
See if you can boot into recovery. If you can. Flash whatever rom you have or nandroid backup.
Also are you sure you're using the correct modem and firmware version? Download those recommended in the rom you're using and flash those along with the rom.

Recently I couldn't boot after flashing different firmware, same with different rom without its firmware and modem.

Cannot install 4.0.2 update

I was using 4.0.0 stock with twrp and root. Tried to install the 4.0.2 update but every boot just took me back to recovery. Tried wiping clean, no change. Tried installing stock recovery v2.0, recovery would hang. Tried using new twrp 3.0.3 and I could get back in, but any ROM, stock or not I installed, would not stick.. Even twrp would warn me "no os installed. reboot anyway?" even when I had just installed a ROM. So in the end I flashed OOS 3.2.8 with twrp and then flashed stock recovery. At this point I'm pretty much at factory stock at v3.2.8 with stock recovery v1.0. Now I'm trying to update to 4.0.2 via OTA and for the 3rd time already I have received a installation failed message and rebooted to system. The first time I thought it was because I disconnected VPN after starting the download, so I downloaded a second and a third time. I don't want to resort to sideloading again because I fear I might get the same no OS installed problem I got when I tried to install 4.0.2 in the first place. Does anyone have any insight on what is wrong?

Steps:
1. Install latest Official or Modified TWRP ( 3.0.3/ 3.0.3 version 14 by eng.stk)
2. Enter into recovery. Connect phone to PC and copy downloaded ROM file.
3. Wipe everything in the recovery- Data, System, cache and Dalvic. It will erase everything.
4. Flash ROM zip after completing, don't reboot phone. Reboot to recovery again, and then reboot phone.
If u reboot phone directly after flashing ROM, u will loose TWRP.

Even twrp would warn me "no os installed. reboot anyway?" even when I had just installed a ROM.

This is pretty normal for nougat OOS. I've faced it for all 3 ROMs i flashed. Don't worry, your ROM was flashed successfully. You can mount and check the /system partition, you can see your ROM files there.
So here's what worked for me. (considering you are on ext4 /data)
1. Flash latest official twrp recovert ext4 version or use the file system swapper zip if it doesn't decrypt your data in recovery. TWRP has some issues as of now and mounts f2fs as default, so you just need to flash the file system swapper zip in order to swap it to ext4 by default.
2. Wipe /system /cache and dalvik cache.
3. Flash full 4.0.2 ROM zip, should be 1.4 GB in size.
4. Flash TWRP image again just in case.
5. Reboot to recovery, not to system.
6. Flash stable 2.79 Super Su and you are good to go.

Thanks for the tip, however I don't mind losing twrp, I only want to get stock unaltered update and this procedure does not help in this

Have you tried this guide: https://forum.xda-developers.com/oneplus-3/how-to/guide-flashing-oos-v4-0-1-custom-rom-t3537757
P.S. I think you did, but I'm just asking.

Thanks for the tip, but I fixed it. Ended up flashing v3.2.8 via twrp and installed OTA to 4.0.1 via sideload. Recovery would not boot unless first fully booted into the system. After that sideloaded 4.0.2 via OTA and now back to complete stock.
Thanks guys!

TWRP gets overwritten

I'm on latest ob18. I am able to flash it, and run it once, but after reboot, the stock recovery gets Back. Any ideas?

Just Reflash twrp via flashify or adb in fastboot mode, that could be normal if u r flash an unmodified stock rom

Yep. On latest ob-Oos or H2o for me recovery stays, after instaltion of the rom. But on a second reboot, stock recovery shows and i reflash custom recovery again.

Guys I flashed latest H2OS beta over OOS Beta18 and lost access to recovery. These are the steps I followed, please help.
1. Backup current ROM (OB18)
2. Dirty Flash New H2OS version
3. Flash recovery image again
4. Reboot system
ROM booted without any problems and all my data is present but I lost access to TWRP.
Solution attempted: Reboot to fastboot and flash recovery image again, the process is successful but still TWRP is not coming up.
Please help. Thanks in advance

How to get back stock color os recovery

I was unable to flash stock rom update(.ozip file) via TWRP recovery. I was also unable to flash stock recovery as any solid download tool was not available. I was also unable to retrieve the ota downloaded in /data partition(/data/Colouros/Ota), if I could that then using ozip decrypting tool, I could have converted the ozip to zip. What I did at the end I locked the bootloader back again which then wiped everything including twrp. I had to presse volume down button while it showed "Can't boot as the image is destroyed...". Finally the device booted me to the initial set up screen and the stock recovery was restored.
This process will erase everything in internal storage.
I posted this as I could not find anything with the link to restore stock color os recovery. I hope it might help somebody.

You have to download the stock ozip file from realme website(https://www.realme.com/in/support/software-update), then convert it to zip(https://forum.xda-developers.com/realme-2-pro/how-to/convert-ozip-to-zip-installing-stock-t4065277), then flash it via twrp, remember to wipe data, as sometimes while reverting back to stock can cause issues, like screen freezing, unable to unlock phone, use subhams recovery(https://drive.google.com/file/d/1Hkv2i0xqzO7o7RrxoFNRHqKyK1Z6eDwD/view?usp=sharing) to flash the stock rom.

If you flash stock rom zip via twrp, twrp will remain, if you relock the bootloader, the phone will format automatically and stock recovery will come back.
