Hello there!
I am running BLA-AL00 10.0.0.180(C00E181R1P4patch01).
Recently I wanted to downgrade to EMUI 9 to unlock the bootloader (I have the code) and here are my failed attempts:
1.Downgrade via dload with OTG
2.Use HiSuite 'System Repair', which popped up with 'No available fix for your device' (btw actually I managed to use this method before, but Huawei seems to block this)
3.Cheat HiSuite to downgrade with Firmware Finder's DNS update (see: link, ended up with ‘failed to install‘, I think this didn't passed verification)
So...are there any other possible ways to downgrade? Thanks a lot!

You don't need to "cheat" hisuite. Just launch hisuite, connect your phone via usb cable, and click on update button. Hisuite will scan for updates and there should be a tab saying previous versions. Just click on it and you should be able to downgrade. Using the dload method and "cheating" hisuite is a great example on how to brick your phone as thats how I managed to brick my huawei(still trying to unbrick). Also what Hisuite "System repair". I only know system recovery or are you referring to that?

Yes, I managed to downgrade via the normal method...
I thought it won't be OK to use this way... because I previously found the 'previous version' tab gone...(about one year ago)
And yes, I mean system recovery. My HiSuite is in Chinese so I just give it a direct translation lol.
Also I often use eRecovery to unbrick, maybe try it out? (I don't know whether international versions have this function or not...)
Problem solved! Thanks a lot!
Now my phone is running Lineage 18! Feeling great!
Can you please explain how did you do that ? I want to get rid of this emui

I got the lineage GSI rom from my friend, I actually doesn't know it's source, seems phh-treble.
NFC doesn't work, and this rom also has a potential storage problem. (actually I don't know whether it is caused by me or not) Just a week ago the rom broke my data partition and I have to reset. Now I have returned to EMUI. The rom is vanilla, and device model doesn't show probably. GAPPS can be installed via TWRP but device model, I tried, can't be modified without Magisk. The rom contains su as well.
If you truly want it, I can upload it to Gdrive. Now I want to downgrade to EMUI 8 and then I can use Openkirin roms, or search for another fit rom.

Hello! I bought an almost new Huawei honor 7 lite and it worked fine, then i did a factory reset just because i wanted to because i started using the phone and there was some **** left in the phone by previous user, and now i can't use the phone without logging in with the account of the previous phone number and i can't reach him anymore. i have tried the swype method and everything but nothing seems to be working. Anyone here know how to get in?

What is your model number and build number??
I have Huawei GR5 (Kii-L05, as known Honor 5x, do not know Kiwi-??, anyone tells me which series of KiWi?),
I unlocked bootloader, and flashed in TWRP and Superuser and rooted it, activated the developer mode. And dialed code to open manufacturer mode and background debug.
Then tried to connect with QPST, but i failed with "unknown phone", I tried all the listed ports, no one works, just like the attached figure.
Somebody said tried custom ROM, Ok.
I flashed cm-13.0-20161227-UNOFFICIAL-kiwi (android 6.0), Cosmic-OS_kiwi_7.1.1_20170419_1.4-OFFICIAL (android 7.1) and lineage-14.1-20170614-nightly-kiwi-signed (android 7.1), they are all good os, but can not solve my problem.
I checked QSPT and usb drivers and keep them update.
But non of them are working.
I use "adb nodaemon server" to find port "5037", it says "can not bind "TCP5037", go to windows processor to find port 5037, no program is running this 5037.
I can not figure out where i am wrong. Please somebody help me this problem.
Thanks in advance.

What exactly is the problem?
Sent from my Honor 8 using XDA Labs
Thanks for your suggestion, i have not tried fastboot mode.
The problem is after rooted my phone, i tried to connect my phone with QPST, but QPST always says unknown phone, so i can not use explore, programming, etc..
By the way my phone system is mm6.01B350. somebody says it maybe the problem of stock rom, so i flashed custom rom, it does not work.
I will keep trying.
Thanks again.
i tried fastboot, at that mode, QPST can not read any port of my phone.
I used driverupdate software to update all my drivers again, there is no any question mark in device manager, please see the following snapped picture.
I did not know what is wrong of my process? I did same job with my ZTE Z826, QPST can read phone information, but for Huawei, i already tried it for almost a month, still can not read phone information with QPST, it always failed with 'unknown phone'.

My last one is Marshmallow 6.01. I already did lots of works on it under rooted condition (rooted by TWRP and superuser, follow this links:https://forum.xda-developers.com/honor-5x/development/root-kiw-l24-usa-kiwi-t3305190).
I tried to factory reset and wanted to roll back to Lollipop 5.0, but failed, looks like after update, can not roll back.
I do not have original stock rom of Lollipop 5.0.
I will keep trying until finding the way to connect with QPST.
Anyway, thanks a lot for your caring my question.

i am trying to read my phone's support networks and go to NV project to modify policyman to unlock my phone network. so i can use this phone for any carrier.
and restore imei.
I download some stock roms which are said to GR5, but they are not, all of them are based on honor 5x. after flashed those stock roms, my phone went to boot loop. have to restore by TWRP.
i do not understand why there are so many series of one model, Like Huawei GR5, there are KII-L21, KII-L22, KII-L23, KII-L03, KII-L05, what are different of those series? I have Kii-L05.
Anybody can tell me?
i found a link :http://consumer.huawei.com/et-en/su...0=Mobile Phones&key1=Smartphones&key2=KII-L21
But it is Kii-L21, do not know it is ok to my phone (kii-l05), wish it works on my phone.

That's it
first go to stock recovery 130 or 140
then use EFS_Professional_2.1.73 to boot in emergency debug (Off device with blue led)
then use QPST 460
i fixed my problem with this method or edit oeminfo backup from some user in hex
this phone use mt6739.so i want to flash it the twrp to my phone.i dunno to unlock the bootloader but the twrp file not have for this device.
I just saw this post as I too have a Honor 7S
There is NO TWRP for our device.
The TWRP for the Honor 7A/7C/7X and Honor 7 doesn't work on our device and you got to pay 4 euros to unlock the bootloader before you can even flash TWRP (and there isn't one)
This Device is treble compatible but now I've found out there is zero development and no Devs Interested in it it's a complete and utter waste of time and has gone back into its box, never to be seen again.
hi there, I get this phone recently (because is old) and I created twrp for i,t so here it is, if you want some fun
you can flash it via flashtool on locked bootloader in to boot partition and after that you push twrp.img via adb to internal storage and flash it in to erecovery and recovery slot, and you are good to go

Hi I have a problem. I'm having brom issues in trying to flash it
Hi
I thinking you dont have "Authentication file" so you using "mtksecurebootdisabler",
so you need patch your drivers with libusb "patch".
Try this one, for me it works.
So open libusb that you install.
connect your honor7s to the pc with disconnected batery and hold volume down.
in patch option select your usb mtk device "idk how is called" and patch it
after patching reconnect phone and it will works.

and little hint
dont flash whole rom if the phone can boot becasue after clean flash "format+download"
you lost log and cust partition because the image files are not secureboot signed and your phone get in to bootloop
and also you lost imei codes so no cellular after that
If you do so
you can fix it in that recovery were I enabled option to format log partition
after you format log to ext4, your phone will boot but without huawei/honor bootanimation
you dont need to worry about cust partition, if you didnt format it it still boot but without bootanimation and you lost some of garbage apps that are in that partition (amazon etc...)
(twrp boots in russian language, idk for now how to change it to boot in english or slovak lanuage (because Im from slovakia) and also it have Lenovo Logo becasuse I use sources from Lenovo A5 that have same cpu)
I will make in future separated thread for this....
Thanks alot for this.. I don't know maybe I should try the disconnected battery. But from a yt link I saw
The link : Honor 7s Dua-Al000
I wonder how his worked
I'll have to know how to disconnect the battery thou. I'm a noob at this.

you can patch it or flash it without disconecting the battery
Here is how:
turn it off
Push and hold volume down
While holding volume down connect usb cable
But is recomended to disconect battery because the phone can boot up instead to go in flash mode.

Well he did with the battery and he add more steps that are not necessary for flashing, like scanning for COM port etc...
When I first try flash my 7s I download flashtool and didn't change any settings, I just load the rom and flash it.
So you must try to find your best way how to do and I will help you
And I wonder how he can flash the Log and Cust partition via flashtool, Maybe he have unlocked bootloader or something
Update: he have in the video description link for "lib usb" but didn't show it in video, or I'm just blind or something

Yeah I see, drivers issues, it happens to me too, but I install windows 7 and everything works... but I think is not worth it to format your laptop and install win7 only for this mediatek crap, where you can't unlock bootloader or anything because Huawei trying to protect customers and they believe that their android is best for they're phones

Hi
When I bought it, it was Nougat 7.0 Beta installed on it. I downgrade to Marshmallow 6 -> https://forum.xda-developers.com/an...ic/xiaomi-mi-box-mdz-16-ab-downgrade-t3737186
I mentioned about this file because: "That is your lifeline to secure you don’t brick or lose functionality on your Mi Box."
Maybe it helps to fix my Mi box .

Once it is is flashed to Oreo, as shown in your screenshot, it is absolutely impossible to downgrade back to any earlier version.
Maybe you can perform 'full system reset' from settings menu.
Then try to invoke 'system update' from settings menu. If that succeeds you will be on latest Oreo 8.0 stable.
Beyond that, I regret I have forgotten all my many Xiaomi mdz-16-ab bag of tricks....
Hello everyone. A couple of days ago, I bricked my huawei mate 10 pro BLA-AL00 by flashing the wrong firmware. After a few days of experimentation, I was able to revive the phone by flashing the board software back onto the phone. Now the problem is that I am on a super early build of emui and it seems like its the stock factory software with a bunch of debugging programs on it. I am having some trouble updating the firmware to android 8. I downloaded this exact firmware file: https://androidhost.ru/bzx
I am having some trouble figuring out what files I need to flash. There is a main dload folder after extracting the files, but if I try to copy that onto a usb drive and flash it using the dload method, my phone will once again brick itself. I have tried flashing the all_cn firmware file using TWRP recovery, but that also bricks my device and puts it into a bootloop. I have also tried using the huawei update file extractor software and tried manually flashing the firmware using fastboot commands, but once again will just end up in a bootloop. Am i doing something wrong? I would really appreciate any help. Thanks
Hi,
I'm in the exactly same case. Did you manage to fix it?

I finally managed to figure everything out after days of research and testing. You must download the BLA-AL00 8.1.0.351 full ota firmware from pro-teammt.ru and extract the update.zip folder. Next, I used MRT Dongle 3.19 cracked to flash the firmware. https://www.gadgetsdr.com/mrt-dongle-latest-crack/ To activate the program, you must use the keygen provided to generate a activation code after pasting in your device id. The device id can be found by opening the mrt program for the first time. Paste in the activation code found by the keygen into the activator and the program should open. Next, click on hw flasher and put your phone into fastboot mode. Make sure your bootloader is unlocked. I assume it is unlocked as you only flashed the board firmware. Under write flash click on the 3 dots near the bottom of the page, select the update.app file you extracted before, and click on start. Don't worry if it says fail for the first few commands. It should successfully flash everything else. Once this process is finished, your phone should reboot. We need to do one final step and write the oeminfo back into the phone. Put your phone back into fastboot mode by plugging in your phone and holding down the power and volume down buttons. In MRT, click on update hw soft_ver, select huawei mate 10 pro, and click on start. After flashing, your phone should reboot normally now into an operating system!!!
Thank you for your answer ! My Mate 10 Pro is BLA-L09, how did you know you have to use this specific firmware (BLA-AL00 8.1.0.351 full ota firmware) for your BLA-AL00? I guess I should use BLA-L09 full ota but which version?

It took me a very long time and a large amount of downloading to figure out the exact firmware I needed to use. I just downloaded a bunch of version and see if it would flash onto my phone. Finally, the 8.1.0.351 firmware worked! For the bla-l09, im not too sure the exact version needed. I would experiment around and try a bunch of different full ota firmware from pro-teammt.ru Maybe you could flash the bla-al00 firmware and rebrand the phone? Im not too familiar with rebranding, but I know its possible.
I have tried with BLA-L09 8.0.0.115 firmware then my phone has reboot in a better factory version (EMUI 8 instead of EMUI 5), but still in factory mode, with the developpers apps. I've done the hw soft_ver update, but it still boot on this factory version. I've tried to flash another firmware (still BLA-L09 but another version), and now my phone stays shut down. I cannot even see it on my COM port. I've tried to use test point, I can hear the USB plug computer song but nothing happen. Phone no detected, black screen, no vibration. I've tested all the possible key combinaison (volume up, volume down, power button), still nothing .
Any idea of a last chance?
I was so close thank to your help!
