After flashing TWRP, will not boot system

Good morning,
I'm sure it's something I'm missing. I had my tablet unlocked and running fine with TWRP. I went to Omni then to Preview 2. All was well.
Last night I decided to try SuperSU 2.72. I factory reset my Pixel C by installing the latest firmware. I then used fastboot to flash TWRP. It goes into TWRP fine but now it will not boot system any longer. It goes directly into TWRP when I have it boot system. Is this an encryption problem. I've tried both TWRP versions and same behavior.
Any idea what I'm doing wrong?
Thanks!

if you have 3.0.2 i think there was a problem with early build causing this. there was a link posted for the new one that supposedly fixed it. or just use the 3.0.0 build.

It seems some people have problems installing the NYCHitman1 TWRP version.
Most of them complaining because of boot problems.
To fix it:
Pls use xceed TWRP 3.0.0-0 version: http://forum.xda-developers.com/pix...official-twrp-2-8-7-0-pixel-c-dragon-t3288243
Or use my repacked TWRP 3.0.2-0 version : TWRP_dragon_3.0.2.0.img
Pls install TWRP via fastboot and boot directly into TWRP.
Install stock kernel (boot.img) via "fastboot" or use the TWRP flashable version from here: Update.ZIP_Nexus_Ryu_MXC89F-kernel_dragon.zip
Install SuperSU.zip 2.72 directly afterwards in TWRP - no reboot in between.

Thanks guys! I did go back to 3.0.0-0 and it now boots into system. I'll also try your repackaged version of 3.0.2-0. I'm on my work PC but I don't see a link to your version. Is my work PC just hiding it or can I find it somewhere else? Thanks again!

Well in case of "recovery bootloop" start your device in bootloader mode and type "fastboot reboot" in command shell. That works mostly. No need to flash another recovery.

And connect everytime with PC to do a manual reboot via fastboot .. seems a little bit too much for a simple reboot. At least for me
A proper TWRP with proper vboot will boot always correctly, like the one from xceed.
Did you ever had to do a manual reboot on his version ?
Should be fixed at the root cause .. Hope you agree ?
Cheers

I think there´s a little missunderstanding
The fastboot command helps you to get out of "recovery bootloop". After this you can reboot your device how offen you want without issues.
And yes with all existing TWRP versions I had some reboot hickups and have solved it with the fastboot method...

Interesting .. I did not have any reboot issues with xceed TWRP versions .. I had to use the fix fastboot option once, but this is another topic.
But thanks for your information ...

[HELP] Unable to flash Stock/TWRP recovery or Any ROM via FASTBOOT(bootloader)

I was on OOS community build 3.5.3 with modified twrp-3.0.2-19-oneplus3.
I wiped everything except internal storage after that I tried to flash official TWRP.
After installing official twrp via modified TWRP. Niether I can boot into my recovery nor able to install any recovery via fastboot.
it I use "fastboot flash recovery recovery.img"
after installing recovery with this command My bootloader get stuck then I have to again restart my bootloader.
please help

You're probably stil on 3.5.2 firmware which isnt compatible with official twrp. Try and get into fastboot and try flashing modified twrp again. Then reboot in recovery and flash 3.2.6 firmware (not the rom) from modified twrp. Then reboot and flash official twrp from recovery or in flashify app.

i had this problem the other day, fixed this by flashing the modified recovery from a post here turn it off the booted it up by holding vol down + power and somehow it worked i was able to go into twrp

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

Hii,
Still the problem remains same I will explain in detail
I am back to cm14.1 when I flashed twrp from the above link
When I tried to flash some other ROMs they are flashed but screen goes blank after oneplus boot animation,
If I flash 14.1 ROM it is working fine
From cmd non of the recovery where flashed only the above is working
Plz help me
I want to go back to stock soon

It's because of the system partition rewriting issue. People in the cm and other communities are already working on it. Basically the boot partitions get rewritten when we install the cm 14.1 . It happens to some variants while others works fine. Just the issue because of not enough testing. Will be sorted out within time.
What you can do is. Use flashify app or fastboot from your pc and flash your twrp back after installing and booting into the cm 14.1. You can use any twrp no modified versions needed as far as it is supported by your device model. Ciao. Hit thanks if i helped.

I had the same problem as OP, got stuck with the CM 14 and did not like it (to early, to many bugs)
Wanted to go back to CM 13 but was unable to get into TWRP, and unable to flash CM13 back. Tried with fastboot and adb sideload, nothing worked.
The modified TWRP let me do i full wipe of the phone, (wiped Data, Dalik/ART, and system.) then copied the CM13 Stable release from here onto the phone, together with Gapps, and now everything is back to normal.
Again thank you, and thanks XDA! Somehow you always manage to save my ass after i messed with my device

Just flash the twrp image file again. The one you used before. Just flash it again. The same way you did back then.

Please help, twrp can't stay and magisk erases the system..

Hi, just received my device, I followed this guide https://forum.xda-developers.com/oneplus-5t/how-to/oneplus-5t-unlock-bootloader-flash-twrp-t3704592 and when I reboot my phone, TWRP is replaced by the default recovery... Also when I flash magisk v15.3 my phone can't boot anymore and i got into fastboot mode.. I am running Oxygen os beta, thanks.
I tried everything, different twrp versions, etc... don't know what to do :/

Once you flash the twrp-recovery.img in fastboot are you using the command
Code:
fastboot boot twrp-recovery.IMG
to get into recovery and flash magisk or are you rebooting the phone?

I tried both the command you writed, and booting the recovery via the volume button in the fastboot mode.
TWRP boots correctly, then I flash oxygen os beta and all is ok, but when i try to return into recovery, i got the oxygen os recovery. When I install magisk I simply can't boot anymore.
I followed the instructions gived in the link

Why are you flashing beta after twrp? All that is doing is replacing TWRP with the stock recovery.
Flash beta and let the phone boot
Enter fastboot and flash twrp
Boot to twrp with command "fastboot boot twrp-recovery.IMG"
Flash magisk
Reboot to system

Bro try installing beta zip through adb sideload from twrp

The key is, after flashing TWRP, DON'T boot into system. Instead, boot into recovery right after flashing TWRP, and flash magisk.
Original OOS will replace the recovery, at least from my experience.

Hi guys, finally solved the problem. I had to download an alternate TWRP ( codeworks ). Also, only the beta version of Magisk worked. Now all is ok, thanks for your help

This has nothing to do with an alternative TWRP, you can't flash the ROM after TWRP, because ROM includes stock recovery, which or course replaces TWRP as it has been said before.
To "manifest" TWRP after flashing it, you need to boot into recovery before booting into the system.
It's quite simple if you just read the probably 100+ available guides.
