Hi there,
sorry, if this was answered before, but I couldn't find the correct answer:
After trying to flash a custom ROM (CMOD) I'm stuck now at the Cyanogen Mod boot animation.
If pressing "Power" button for a while the phone reboots, but gives me again the same boot animation (after ZUK logo).
If pressing "Power" + "Volume +" + "Volume -" buttons for a while the phone reboots, but gives me again the same boot animation (after ZUK logo).
The phone is not recognized via USB on a computer.
Anybody has still an idea what I could do?
Many thanks in advance for hints
best regards

What are the steps you followed before you ended up in this situation? What rom were you previously on? Provide as much details as you can without being redundant.

I was coming from latest stock. The attempt was to flash CM14.
1.) flash in the thread linked twrp
2.) flash CM14 and Nougat GAPPS micro
3.) reboot ok
4.) fingerprint didn't react, so went back to recovery and flashed both again, causing this loop
many thanks again for any help/hint

If the first time boot with the rom and gapps was okay, maybe you should try wiping /system, /data, /dalvik and /cache and reflash the rom again.. Since you were in stock cmos 12.1, I think it'll be better if you flash official cm13 first, and then jump to cm14 from there to minimize sensor issues such as with the fingerprint like you experienced.

Mate if you think you're done with everything and nothing seems to help, just search around here how to flash ZUI using QPST. That's the last resort which saves your device from the gravest issues.
However, let me know if you can or can't find that thread or anything else, I'll be happy to help. :good:

There are many reasons for a bootloop. Start from scratch once again. Flash stock cos12.1 (or restore if you have a backup), flash cm13 from there after you load twrp, go from cm13 to cm14. I think this should be the way to go to avoid sensor issues. Once in stock, you can go from there. Good luck.

This is the thread link right here explaining all the steps (although it's a little tricky to follow )
That was the good part....
The worst part is that the download links are dead
I'll try snooping around more and see if I can find anything else and you should try too since the thread will give you an idea what to look for.
If the search comes up empty, I'll upload the files tomorrow by all means

Power button + volume up gets you into recovery mode.
(I think) Power button + volume down gets you into fastboot mode. Not sure about this one, you can search around for the key combo to get into specific modes. From fastboot mode, you can flash the stock cos 12.1 provided from the official support page of cyanogen. Make sure you download the zip compatible with fastboot mode. When you finally get to cos 12.1, you can install Twrp recovery (also available among the forum threads or from the official twrp website), then flash cm13, reboot to check if everything works and then finally move to cm14.
You can post here in case of problems/confusions in any step.
Alternately, in place of cos12.1, you can flash zui as suggested. Search in the 'help, q/a' section of zuk z1 in this forum. You can find the tutorial there. Good luck.

Hi,
after draining the battery (and loading up a bit) I could get access to fastboot. From there I flashed latest twrp (3.0.2) and booted into twrp.
From twrp I wiped and then flashed latest Nuclear ROM & Gapps. After rebooting I'm still ending up in twrp, again?
PS: flashing the cos 12.1 via fastboot mode didn't work, due to below:
"
fastboot -i 0x2b4c update cm-12.1-YOG4PAS9IG-ham-signed-fastboot-b9cce4220b.zip

reboot device
fastboot -i 0x2b4c flash system system.img
fastboot -i 0x2b4c flash boot boot.img
fastboot -i 0x2b4c flash recovery recovery.img
fastboot -i 0x2b4c flash cache cache.img
fastboot -i 0x2b4c flash userdata userdata.img
fastboot reboot
Then I was back to stock. After that I started from scratch to flash twrp, Nuclear and Gapps.
Many thanks to all that helped!

stuck with same situation plz need help
So for some background, I was on EMUI 4.1 and successfully flashed to EMUI 5.
Then, I wanted to rollback so I flashed recovery again and stock firmware. I tried flashing with fastboot and didn't work. I tried using Huawei recovery 3-button method, no luck either.
Errors using fastboot flashing:

When I was booting into Revolution recovery, I could not mount SD card and some other partitions so maybe that has something to do with the 3-button method problem... Furthermore, I don't know how to check which version exactly my phone is, all I know is that it was VNS-L31.
Now I'm stuck with a phone that is constantly rebooting so how do I proceed?
First of all...
Please tell me you have a backup of your Nougat ROM. If yes, restore it.
I have failed to go back to MM several times like you before.
It really is a question of using the right files.
First, flash the OEMInfo that is provided here in the forums.
Second, flash the right firmware. This one is tricky. For me, ONLY VNS-L31 Version C150 worked. No other.
Flashing with fastboot always never works. It always gives an error on system. So you need to find a firmware that works with 3-button method.
Your task now is the get back to working Nougat, since you did something wrong.
Unlock BL, flash Nougat recovery with fastboot.
Then,
easiest is like I said restoring a backup.
If you don't have one, try flashing the Revolution ROM by BadWolf.

Have just solved the problem with the steps from here.
From my understanding, it seems that I lost almost everything, device info, OEM info, recovery... So no technique was working.
The solution in brief was:
1. Go into bootloader to flash recovery (I used Revolution Recovery)
2. In recovery, flash OEM info.
3. Then used the 3-button method to install stock version for the appropriate model (which I could see from OEM info).
4. Unlocked bootloader, triggering a factory reset. (I was stuck in infinite boot before this point.)
As you say Schlengge, it is a matter of using the right files! Thanks. Problem solved.
I constantly encounter roadblocks on this phone. Have not had issues with my OP3, Le Max 2, older Note 4 and Nexus 6 . If ZTE is pro this community, why are things not straightforward? On the OP3, simple lock and unlock commands and flash away. Got to do this and do that, 1001 different ideas from people. Right now, my BL is unlocked and I am trying to reinstall TWRP after upgrading to Nougat. This is the message I get when running my adb command to flash recovery:
I have an unlocked BL and recently upgraded to Nougat, but when I try to reinstall TWRP via fastboot flash method, it fails. I have tried two different versions of TWRP 3.0.3-1 & 3.0.4-1. This is the message I get.

It is possible rigth now, for a A2017U full stock in NOUGAT (no unlock, no root) to flash TWRP and jump to LineajeOS 14.1 ?
Thanks
Happened to me. Didn't figure it out on there. You have to re unlock the bootloader to get it to work as it currently shows unlocked but is in fact partially locked. I used the bl unlock kit available and ew unlocked the bootloader then jumped to lineage os. You must get to a point in the zip where it says to fastboot oem unlock and instead type fastboot oem lock. Then start the zip guide from the very beginning again
It's not that difficult, it's just different from hacking a Samsung/HTC device. Just be patient and read. We've all had those same problems and there are workarounds to those problems. But the problem you're running into is you don't have the proper fastboot installed that allows fastboot commands.

I bought a new Moto G6 Plus XT1926. My goal is to install a twrp image as recovery and then next the lineage.
I got a weird issue when trying to flash "twrp-3.2.1-37-evert.img" on my 1926 by using "./fastboot flash recovery twrp-3.2.1-37-evert.img" on a mac console. The output is:

Just before I unlocked the Bootloader. I tried:
1. Locking bootloader again and flash => nope
2. Restoring the partition table by the following commands:
./fastboot oem fb_mode_set
./fastboot flash partition gpt.bin
./fastboot flash bootloader bootloader.img
./fastboot flash logo logo.bin
./fastboot flash boot boot.img
Does anyone know why the partition "recovery" may be not present and how to make it flashable?
I flashed a XT1039 multiple times without issues, so I got some experiences. But i am out of ideas here.
How can it be that there simple is no recover on the phone I wonder.
Also I downloaded the "TWRP official" App and installed it within the Moto G stock rom and it also says that it can not locate the recovery.
I tried some stuff for two evenings and now i do not know how to continue...
Thanks for hints!
The Recovery is inside the boot, that's why the G6Plus don't have an official TWRP.
The ones we have are the bootable one with decryption enabled, or a flashable one with no decryption
So instead of flashing the TWRP to the recovery partition, I should flash it to the boot partition?

No. Do not flash it at all! Load bootloader on your phone, from a pc with a fb and fastboot on it, run "fastboot boot twrp.img" without quotes and twrp.img matches the filename of the twrp IMG file. At this time we can not install twrp to our device. We can only boot it on our device using a pc every single time you need twrp. There was a twrp.img for our device we could flash with fastboot to install on our device but it does not properly flash files sadly. We are trying to raise funds to buy a device for a recognized developer in hopes of making some real progress on modding this device! Look around the G6 forums here and find the thread if you are able to make a PayPal donation or would like to see if you could donate in another way.

What says when you tried to flash the vendor with twrp?
first check if you using the newest fastboot version via: fastboot --version
are u sure that you have the EEA Hardware?
when u have access to twrp(recovery) try sideload via adb sideload
and here is a how to flash manually link:

this could happen to you with any device! for me the 7A is a really great device. if you unlocked your bootloader you know that there is always a chance to brick your phone! so take responsibility for your actions and don't blame the manufacturer.
PS: if you use more dots and enter it would be much more better to read through your post if someone is trying to help :/
I am also not responsible if anything goes wrong.
May be your download file is corrupted, have you checked the integrity of that file, the extension (.tgz) fastboot firmware.
And flash them with mitool and always download from official site.
