Did you tried also to flash something? (Root or xposed)

Not until now, but if you have something reliable to flash for rooting I will try it.
There was the guide for rooting the Honor 7, but I don't know if it is only for the chinese version?

Actually I've seen only that one, dunno if it would work. I'm like that my order is "waiting for stock" so other can try for me. XD

Worked for me

This method worked for me, so thanks to OP.
As fastboot oem get-bootinfo shows the Bootloader as unlocked.
I flashed a Chinese TWRP from the guide I found elsewhere here. It definitely boots into TWRP and everything works inside TWRP, albeit in Chinese.
Unfortunately, I'm now in a TWRP bootloop and can't get out of it.
I don't have a stock ROM/recovery to re-flash, so I'm hosed until one appears online.

Is it useful to try it without an recovery image available? Some other user tried it and is in a bootloop now without the possibility to recover.

I also slashed beta-supersu, using the Chinese twrp. I didn't reboot in between flashing twrp and supersu. Maybe I should have.

Thanks!
Works perfect for me

What to do with the unlock code? I mean where to enter it?

Using your tip, I made this http://androidmtk.com/unlock-bootloader-of-huawei-honor-7

I get stuck on the step 10: after I fill everything out, it says "Sorry, you must use a phone account to submit this application."

I had this too. I needed to log in at the first step with a Facebook account. Basically Huawei want a record of who they've given codes to.

Did you figure out how to get out of the bootloop? Did you successfully root it?

Yes. Though mine seemed even more complex. I couldn't boot into the bootloader that way.
What I found is that via some combination of volume/power keys and having power plugged in or not, I finally:
* did a boot into safe-mode
* discovered I was rooted
* used to to install ROM manager
* rebooted, out of safe mode
* ran ROM manager
* rebooted to bootloader
And then did what dukey said.

strange i have tried to log using facebook button but it keeps sending me the '"Sorry, you must use a phone account to submit this application."'
any ideas?

Has anybody else got stuck here or knows how to get around it?
I have not received an answer to the mail I sent them yesterday - I hope somebody replies at all
lippl

The .exe linked in the first post is not required to determine the product ID. It can be determined using universal code *#*#1357946#*#* (which returns an 8-digit code as expected)
Further, the .exe linked in the first post does not get a clean bill of health at VirusTotal - nothing definitive but not clean. Anyone planning to use it to generate an unlock code should use reasonable caution, sandbox the application or (better) run it on a disposable VM.

since you already have twrp installed, try flashing stock rom in this page - http://forum.xda-developers.com/moto-x-play/general/rom-xt1563-brasil-stock-6-0-twrp-t3272979

You could reboot the phone into recovery and connect the phone to the computer. You could then mount the USB storage onto the computer and simply copy paste the zip into the storage. Although I'm not up to date with the features of the current TWRP, but the mount USB storage option was present in a previous version of it. I dunno whether it's still there or not, but still worth a try.

Thanks a lot! it worked

Dude this is not an error. It is an usual thing! Just try rebooting the phone and it will work!!!
Error text is in red and white text is usual.
Before calling it an error please make sure that everything you try doesn't work!
In the image you can even see the text saying "scriot succeeded"

You are using the wrong bootloaders... You need to be on lollipop and twrp for lollipop to use any AOSP rom like any of the Nougat ones.

Not an error!! Just be sure to have ll and twrp. After flashing just reboot into system. Don't mind the thing with filesystem. Try rebooting. If you get green lines you have a rom made for the wrong bootloader. Try any Nougat rom. It will work!

Had the same problem..I installed a custom rom and then wiped cache and dalvik cache and it worked.

Dude i had the same problem.
Hi dude,
I had the same problem you are experiencing in my Lenovo a7000
I just tried 2 roms whic are (Viper 2.0 and Viper 3.1) both are official.
While flashing it i got something like
Script Succeed please Reboot
and
Detected File System Ext 4 dev/block and bla bla bla
and i rebooted the phone stucked on the boot logo (ie:Lenovo)
i just tried another rom (dot os)
first of all i just got the same text their before rebooting i flashed the open gapps and like a magic it worked.
I don't know what problem is but the solution is Flashing GApps after flashing the rom.
Hope it works.
Please Do Reply after trying this.

LG H440n - LineageOS problem + cannot reinstall OS - HELP!

Hi there,
few months ago i flashed LineageOS 14.1 and so far it worked so good. BUT! Few days ago i find out that i can't pickup any phonecall - i can hear the sound of the call, but nothing is showing up on the screen. I did the factory reset, but nothing changed. So I decided to reinstall ROM. And there is a problem. Coz of the 7.1.2 Lingeage Androig version i can't root it by kingroot. Tried to use LG UP and LG FLASH TOOL - to change rom, its not finding out my phone at all (the pc is recognizing it fine - all drivers are up). Got the TWRP on my phone, downloaded c70n - but without root how am I supposed to flash recovery (flashify is not working). Got no idea what to do.. Please help, get me some instructions how reinstall rom (even to stock one) that may work
PS. Sorry for my bad english.

If your phone is not rooted then you can't do anything. You can also try kingroot to root nougat( not sure if it works on nougat )
If it doesn't work then you'll have to flash the lollipop again.

If he's on lineageos he has to have twrp
The problem is that his version is probably the first one that has the bug that when you try to get into it using the key combination it just wipes the phone, that has been solved in official versions of twrp for h440 but the first one had that issue

Already tried before posting. OEM unlock and USB debugging is not activated, so the phone's not taking a custom recovery. Downloaded 10+ different firmwares from sammobile, still AP is returning with invalid MD5 error in ODIN. Some even can't unzip. Same results on 2 computers. Don't know what am doing wrong.

OK bro. just try this last steps.
Found some bootloader and modem thanks to this person djb77. here is the link for his rom,
https://forum.xda-developers.com/s7-edge/development/rom-galaxy-project-t3792787
just click on link below and download modem and BL.
Here is his modem link
https://androidfilehost.com/?w=files&flid=271403
and here is bootloader link
https://androidfilehost.com/?w=files&flid=271397
CLick on your device version in the link and select the modem and BL of May 16, 2019 and download them as they are latest.
Now i hope you already know that you must have installed samsung driver and you must be using Odin3_v3.13.1
Now boot in download and connect it to pc. if desktop use the backports of usb. Now in odin(try run it as admin sometime) click on BL and select the Bootloader which you have downloaded. And then click CP and select the modem you have downloaded. and click start. Sometime antivirus mess things up too. Try turning it off too.
this is last from me brother. if it works which i pray it should then i would be glad. if it doesn't work. then i am sorry bro.

NISAR Ahmed NISAR is helping me get if fixed. Some progress as it took some rom on Odin, not booting to recovery now, but stuck on boot screen. Hopefully tonight.

Just my two cents-- but I'll bet you might be using the wrong version of Odin. I was in a similar bootloop after I tried flashing it with an Odin I found in some S7 Edge threads and it kept failing with all different types of firmwares. Odin3_v3.13.1_3B_PatcheD is the version that worked for me.

That is true, use correct odin version plus correct rom plus correct method, always know what you are doing or there is a chance you will even make conditions worse..
Also, be specific in your op, tell what you were doing when that started happening, which rom were you using before and your exact model and firmware, so others can help you easily and readers may get a benefit if there is a solution.
Pls, this is not general help forum, post all help related queries on related forum.
