Hello,
after flashing recovery with latest TWRP (twrp-3.1.0-0-bullhead - md5 checked), I restarted the bootloader (fastboot restart-bootloader)
But from that point on, the phone only showed a black screen. it still shows in fastboot devices and boots, possibly to the pin-check. power volume down makes a screen capture sound there.
No screen in bootloader, no screen on boot. Only thing that seems to happen is the backlight switching.
Tried to restore factory defaults with the flash all bat from the stock builds, fastloader -w and the flash stock & unroot option from latest nexus root toolkit.
Does anyone have any other idea what I can try?
thanks in advance

I've never seen anyone restart the bootloader. Reboot but not restart. Hopefully they are the same but I have not a clue as to what that does to your phone after flashing recovery. For future reference after flashing recovery, boot into recovery, once in recovery, I always reboot to recovery again, then flash supersu.
I'm glad you have fastboot still. You could try this, flash_all again. Afterwards, boot into TWRP (don't install) do a factory reset and then reboot. Make sure your flash-all is installing everything. I always flash mine one at a time. Good luck

Thank you for the reply. I will try a flash all with TWRP again.
as for the restart - i just looked it up - it was a reboot-bootloader command. Misspelled there.

Hey guys. So here's the thing. I unlocked the zuk's z2 bootloader using the standard method (fastboot -i 0x2b4c flash unlock unlock_bootloader.img, with the img they sent me via email, and then fastboot -i 0x2b4c oem unlock-go), and then I went to flash the TWRP recovery. I downloaded the recovery image from the official twrp website and proceeded to flash it with "fastboot -i 0x2b4c flash recovery twrp.img". The flashing was successful. But before restarting the device, I chose the option to boot into recovery, so that the original recovery wouldn't overwrite TWRP. However, the phone does not boot into the recovery, ever. It "shuts down", tries to boot into recovery, and without showing anything on the screen simply restarts to the normal system. Even flashing a stock ROM in the phone with MiFlash (relocking the bootloader) and trying to boot into the stock recovery does not work.
And, the only method to boot into any recovery that works is to use "fastboot -i 0x2b4c boot recovery.img". But as we know this isn't permanent.
Anyways, sorry for the wall of text, I wanted to make sure what I said was clear Please help guys, what should I do??

Why not flash twrp as an image file while in non permanent twrp? And while you're there flash supersu too.

I did manage to flash a custom ROM, GApps and Magisk with the temporary TWRP and everything worked. But I just flashed the TWRP image as you said and the flash was successful, but the phone still doesn't boot into recovery
WTF is going on?? Its kinda like the image is being flashed correctly, but the phone fails to access the recovery partition to boot it... Halp!
Edit: Flashing via flashify also didn't work...

As that window on boot shows that in 5 sec. to push anything, choose from that window Boot to bootloader, from there using volume buttons choose boot to recovery, it will reboot, wait those 5 secs and immediately after that window gone keep pushing both volume buttons and it should boot your recovery - it's the same for me and idk why

Its works!!!1!! Much thanks mate!
Still though, it's really annoying having to do that every time to boot to recovery... If i figure out why that happens I'll shed some light here... And Would also be grateful if anyone who knows the reason for it explains why

As you said, is a patience problem:
I had the same problem and beeing serious I was very desperate, I tried and tried for weeks and nothing! BUT BRO! It was just beeing patient! You did it! You flashed the TWRP, now is just to wait!:
1. Turn on your device
2. Press volume keys to enter to the fastboot menu
3. Choose Recovery
4. Now the device will reboot and show the same thing as always(ZUK,Bootloader is unlocked,blablabla.), and here is when all starts, YOU NEED TO WAIT 5 SECONDS BRO!, AND THEN IT WILL BOOT TO TWRP!
5. Thats all, you're on!
P.D.: Apologize me for bad english :'v

Hello everyone. I got a M8s from a friend wich is stuck in bootloader. The recovery didn't work at the begin, so I flashed twrp-recovery-2.8.6.0-m8s-qlul.img (flashing recovery using htc_fastboot.exe flash recovery theimagename.img) and it worked, then I tried to install a custom ROM Android_Pandora_Rom_1.2_(Discontinued).zip wich went all the steps fine until: Optimizing applications 8 of 204..then phone shat down to black screen. I booted back to bootloader, recovery, wiped and go for a new install, same issue.
After that, I was going to install lineage-13.0-20170715-UNOFFICIAL-m8qlul.zip where the developer of this rom recommends twrp-3.0.2-0-m8ql.img so I tried to flash it (flashing recovery using htc_fastboot.exe flash recovery theimagename.img), then tried to acces recovery, brings me back to bootloader so fast, rebooted bootloader, tried again, same problem. Tried the fasboot erase cache, no help.
The Hboot state is Unlocked and the S is ON. I tried some other recovery images, as stock_signed or 3.0.1, tried the one from M8 ToolKit but all failed and I still can't access recovery, everyting I do, it brings me back to bootloader. I did htc_fastboot boot recoveryfile.img wich works, but useless, the dd if= method to set the recovery permanent load did not work after reboot, /data and /system can't be mountet, it seems the "boot recovery" option is 99% readonly.
Any advice, any help please? It would be much appreciated! Thanks in advance!
Hi McBad,
you could try the following. I also had some problems to access the recovery.
- Again bring the phone into fastboot, flash the 2.8 recovery and access it
- Do a wipe for factory reset, not just only cache
- after that try to flash the twrp-3.0.1-0-m8ql.img version, the other one worked for me neither
- the try to install the custom ROM LOS13
I hope this will help you.

It would be great if that would work, but flashing a recovery does not work. I flash it, success message, try to access it, vibrates and bootloader pops back instantly. That is the problem.
Sorry for double post, but can anyone help me with this? This is the second day I struggle to make it work. Any chance to make the hboot locked again? It didn't work with oem lock command. I would like to lock it so I can put an official zip on sdcard so the hboot to restore it to factory stock, some RUU. Or get it s-off so I can flash a rom from fastboot? The phone does not have any ROM on it, image crc results system 0x0, recovery 0x0. Please, help!
Have you tried sideloading twrp ?

Did you use HTC fastboot ?
Yes, I used htc_fastboot. Use sideloading? Like boot the img file directly? Tried that too.

Is there any way you could flash twrp 2.8 again? Once in that recovery you have sideloading option which you could use to transfer latest recovery onto your device. Are we talking about the same process?

You can't install lineage if you haven't upgraded your device with latest official update. I would try reinstaling twrp 2.8, do a wipe of cache, dalvik cache and system, Sideload CM 12; and see how it goes. As well, while in twrp I would try relocking bootloader but only after an unsuccessful attempt to flash said rom. I don't know what your experience with soft bricked devices is, but sometimes it takes a while, different usb cable or usb slot on your PC, correct files in adb folder, re-download of rom or recovery because it easily gets corrupted while downloading. And obviously a fully charged device. Let us know how it goes.
I just got my 5t a couple of days back. Unlocked the bootloader and used Blu spark twrp and magisk beta for root.
On restart phone would boot up to one plus logo, and then just go black. The notification light goes on. But nothing else.
Help please?
Edit FIXED(No data loss)
1. Boot into TWRP, clear cache. Hard reset(Volume up + Power from a switched off state).
2. Boot back into twrp.
3. Adb push full zip(Found here - Signed Flashable Zip)(Adb push follows this syntax - adb push /(filename).zip /storage/
4. On twrp goto the install menu, navigate to storage and install the file.
5. Optionally you may clear the cache and then install magisk. I couldn't get it to work without magisk but YMMW
Do a hard reset if you still can...

Already did that, multiple times. No success.
Same happened to me. It eventually forced into a fastboot bootloop. I had to flash and boot twrp from fastboot again, and then flash the full ota zip and essentially start over.
Decided to skip the root though, until there is a solid ROM release or a stable magisk.

I tried a similar approach. Cleared dalvik, hard reset then booted into Blu twrp. Flashed Full zip and then magisk again. Booted right up.

Yes that was one of my many troubleshooting steps as well, didn't work for me.
Can you help me with this, having a similar issue when I tried to unroot and screwed everything up.
Can anyone help me with this? I'm trying to push via adb the stock os and it looks successful but I don't see it in TWRP.
It's not a big issue, you just flashed the wrong magisk, just boot into recovery and re flash the stock OS
With this type of brick, if u r able to access recovery just go amd reflash, this is not a major brick
Solved
It probably would help to explain how it was solved so that other people with the same issue find a solution
Probably a soft brick!........nothing to worry as long as twrp is intact you can flash any other rom without formatting the data. Even if twrp is gone, boot into the fastboot mode and flash twrp and you are good to go.

I have the same issue. reboot to black screen. can't boot to recovery or fastboot, just black screen. I have to long press power button to turn it off then reboot.
I am on Resurrection Remix 8.1.
How can I get recovery and fastboot back?
Thanks!
Hi! I've unlocked bootloader, latest TWRP and Latest AICP. No root. The phone will never boot to System from power off, from TWRP or normal reboot.
It will, however boot normally from bootloader screen, when I choose Start.
Have already wiped every partition, tried to reinstall ROM, the problem always persists.
Any idea what is causing this?
Thanks
