Resolved - L29C567B190->Build NRD90M Test-keys-> DLOAD fix fails -> Now Boot Looping
I've been working on the path to have my Mate 9 unlocked, rebranded, and to Pie.
I followed this guide. Not sure why, but I ended up with this:
TWRP Recovery (expected thisi)
Not upgraded to Oreo (unexpected)
Build: NRD90M Test-keys (unexpected and problematic)
I've read that I need to re-install the MHA-L29C567B190 again.
So, I attempted 2-3 times with different downloaded (supposedly MHA-L29C567B190) firmwares to just use TWRP to upgrade. All failed. So, I decided to put a DLOAD directory with the files required onto my SD card and upgrade from the Project Menu.
Of course, I had to reinstall the default recovery to do that. I did that using fastboot.
So at this point, I'm thinking I can do the reinstall of MHA-L29C567B190. So, I did this:
Launched Project Menu (*#*#2846579#*#*)
Select 4. Software Update
1. SDCard Upgrade
Phone restarts and starts the upgrade
I get this message
Software install failed!
Incompatibility with current version. Please download the correct update package.
Click to expand...
Click to collapse
So I presume I get that error because NRD90M Test-keys doesn't even have any compatible versions. I am certain I downloaded the files for MHA-L29C567B190.
Anyone have any suggestions how I can reinstall the Nouget MHA-L29C567B190 over NRD90M Test-keys?
If I can get that fixed, I can struggle again with rebranding.
Any help appreciated.

So, I went out and studied the rebrand instructions, and finally found that I misspelled the HWOTA directory on the SD Card. So I ran that again.
This time it appeared to be working on the install of the 432 software at the end of the process. But it failed for some reason.
Now I'm in a boot loop. My very first. Should I celebrate my first?
So, now on a search to find how to get out of the boot loop. I've tried the various options I do have from the boots into recovery. Exact naming of process I list below may not be accurate, but you'll probably get the idea:
Tried the option to download latest version and image...failed
Tried doing a factory reset...failed
Tried following the rebrand process once more. same results.

Update on attempt to fix bootloop...
I followed this article to repair. I downloaded a fresh c567b190 file, and copied the update.app into dload. Did a force install per the instructions...it failed.
I had another one from a different download site. It failed.
I tried a 432 file from what I was trying to rebrand to. It failed. I do find it interesting that supposedly same files downloaded from different sites are different sizes. As well, some instructions say to only copy update.app to dload, and others say to copy entire set of files/folders that are in the file that update.app is in.
Beginning to worry this phone is toast.
I'm going to search out other 'remedies'.
[EDIT]
I'm pretty sure that the build showing as NRD90M is causing my problems. I suspect the bootloader is checking against the version and "nothing is compatible" with it. So being in a bootloop with the additional problem of wrong build identification is making this difficult.

I don't know if anyone after weekend will see this and/or have any suggestions, but I'll keep updating as I learn things or stumble onto new obstacles.
I do have some success to express.
I used this thread and it got me booted, into Oreo, and a good build.
BUT...(as always)
The instructions on that thread are to unbrick, and install the rebrand files at the same time. However, during the TWRP Install process (after getting Oreo 8.0.0.046(0409) installed. It was supposed to boot into TWRP after installing it, and do that update.
But, yet another error: during TWRP install attempt, got an error about partition size (don't recall if it was too long or short or what. If anyone needs to know to help me get past this I can run it again).
So, the batch file was waiting at a prompt for me to load TWRP so it could continue. But no TWRP. So I found a TWRP for Oreo, and installed it. I then hit the ENTER key for it to continue, but it didn't.
I loaded Firmware Finder on the phone, and it found nothing to work with it. I have no idea what Oreo 8.0.0.046(0409) is even for, or what region it would be from. Can't find it even with Google.
So, here's what I need help with
What's the best way to get to MHA-L29 C432(Europe). Would it be as simple as adding my l29 model in FF, downloading c432, and installing via TWRP? Another way better?
I think I'm off of the keyboards and phone for a while. It's been quite a chase.
Hopefully I'll get some feedback early next week on how to progress.

I as thinking I had the right firmware, MHA-L29C432B194. But as I think about it, I didn't get that from FF. When I add a model of MHA-L29C432B194 in FF, and search, I find it, but I'm not sure which one I need. I understand I need FullOTA-MF-PV for dload. What is there is FULLOTA-MF, and OTA-MF . I suspect it depends on which method of install I use.
I"m thinking about trying booting to TWRP, and 'install' the ZIPS for the firmware. But I haven't seen confirmation that will work. I don't want to end up in another bootloop.

at the end what u want to do ? tell me ?

I have fixed the bootloop problem from a search that I found a tutorial. The problem now is that it left me on an Orea that oeminfo (cust) is lost. It's not recognized as a valid rom.
I have another thread that has migrated to this topic. I think someone there is gathering tools for me.
I apparently need to downgrade to Nouget, and start over my efforts to migrate to c432, which then will auto upgrade me to Pie. Problem so far at this point is finding a good HWOTA8 file. All searches I find that have links are dead links.

if someone gather it let him work. give me what exacly rom u need, full name

Sorry. I am not getting the email notifications of updates. Apparently sometime in the past, I opened a different account here with my current email. It won't let me update my email address here as it is used in that other account. I've tried the Forgot password thing, but the reCAPTCHA just circles and circles and never lets me make the request.
Back on topic: I got it all worked out. I had another thread on topic of the beginning of my process that was pretty much done. But conversation struck back up, and it continued on to a fix for this problem. It's a bit lengthy, and I learned a lot there, thanks to @zgfg.
If anyone wants to see how this was resolved, you can start at Post # 60 at this thread.
Thanks folks for your input here.

ADB keeps restarting to recovery

Hi all, i own a Samsung S8+, model G955FD. I was following the steps on "https://www.xda-developers.com/how-to-install-android-oreo-on-the-samsung-galaxy-s8-s8-exynos/" to get Oreo on my device, but i encountered the problem User besnik_limani encountered as seen in the comments. To sum it up, after installing the first AQL5 to ZRA5.zip file, the phone keeps restarting when I try to get it to Update from ADB. So now I am stuck with a phone that is running Oreo beta 6 (I think it is?).
Anyone knows a fix to get my ADB back up again so i can update the 2nd ZIP file?
Also, while running on this version, would i still get OTA software updates?
Any help would be much appreciated, thanks!
Same problem here, whenever i press aply udate from adb, i get mini restart, and the phone is back into recovery, while the erros in the recovery itself are
:
fail to open recovery_cause no such file or directory
reboot recovery cause_is unknown or something like that.
Anyone find solution?
Isn't this firmware is for is for G955F?
G955F and G955FD is actually difference device as the second one is Duo version.
I encountered this problem too. But when I tried to put the update in the sdcard, i got `footer is invalid`. Now I will go back to nougat by downloading the original firmware.

I was getting the restart as soon as I selected apply update via ADB. To solve this I set up the phone and dragged the zip to the SD card and flashed it in stock.
Be warned though, the bootloader becomes locked on some for about 7 days. You won't be able to flash a custom recovery nor root. I made the mistake now I have to wait.

Need some help. Possibly bricked

So i tried installing a custom ROM and stupid me forgot to back everything up. Im now stuck in a bootloop. I have access to TWRP recovery and fastboot via adb. My system partition is damaged and i cant use the factory erecovery to undo the damage done. Any tips?
I had the same experience in my BLN-L24 US variant, you just need to use the dload method https://forum.xda-developers.com/showpost.php?p=73954487&postcount=240
I would add something, the instructions say that you need the "FullOTA-MF" file, while that is correct, sometimes (happened to me) that one doesn't work and the restore process fails at 5%, in that case you should try older ones or even "FullOTA-MF-PV" (which is the one that worked for me). Once you get the correct one you should be fine. After that, you may have some little bugs like the compilation number not matching with the one you dloaded and the EMUI version you should have, that is solved by forcing to install (using the Firmware Finder app) IN ORDER the following updates after the one you dloaded.

Honor 6x OTA update bln24 B365 to B376-Full

What I don't understand is there are all these talented people out there, finding ways to do virtually anything to their phones, but there doesn't seem to be any normal solution to receiving an OTA update on a phone that has twrp and rooted and just install the update. The phone is obviously getting the right update, it restarts to install and twrp fails with error 7. There are all kinds of people saying "unpack the zip, remove the asserts line, which doesn't work, at least for this update. Also try using the dload method, but really the ultimate question is, why hasn't a simple solution to just installing this ever have been found? Is the way that all this stuff works in the background just so difficult that a legit update cannot be installed because the stock recovery isn't present? and if so, why can't a way around this obstacle be found.
I would just like to install updates as they come down (i assume by now this phone is trying to work its way up to android 8, or oreo) but i am stuck just ignoring it. I don't mind a little messing around to get things to work, i just haven't found any that actually do and don't involve wiping out the phone and installing everything again. Any answers are appreciated.
Dude. There is a way. I had the same thought before I pressed search on XDA and spent the next 3 hours digging in every Honor Forum and XDA and here is my tried and tested solution.
Make sure you have TWRP installed.
Download Firmware Finder from the Play store, enter your Model Number and download latest FULL-OTA for it. Only Full OTA will work.
Search for and Download Hurupdater from thread. Specifically Hurupdater 0.4
Rename files as specified in Hurupdater thread. Transfer them and Hurupdater to same folder on SD card. i.e all 4 files need to be in same folder. Now boot into TWRP and select Only Hurupdater to flash. Press Volume down when promoted and sit back for a few minutes. Once it completes wipe Dalvik Cache and Reboot.
Now you are on the firmware you wanted without factory reset.
A few things to note.
Your device shouldn't be Rooted. Unrooted first.
First boot will take some time approx. 10 mins. Don't Panic
After update TWRP will be overwritten. Reflash TWRP.
Don't use this to go from EMUI 5 to 8. You will brick your phone
In Firmware Finder there will be three Zips. Rename them as follows:
Update.zip -> don't rename
Update_data_full_public.zip -> update_data_public.zip
Last one will be region specific with your model number. Rename it to update_all_hw.zip
Good Luck.

Ok, I'll give it a shot and respond later. Like I said, I don't mind jumping through a few hoops. One question, how can I make sure whatever latest full OTA is doesn't have emui 8 in it? will that firmware finder point out what is in it?
If it has EMUI 8 it will be mentioned in the title of the firmware like 8.0.0.536 or something. Currently only India and China have EMUI 8. However to be safe I advise you to go to system update and Download & install. It will Download firmware and ask you to install. Hit cancel and using file explorer go to internal storage. There will be a folder named HwOUC. You will find three firmwares archives there. Use them. Make sure they are Full OTA by checking the size of archives. Update.zip should be at least greater than 1 GB

Yeah, I looked in the changelog, and it isn't emui 8. Plus it not being available in the USA kinda answers that as well I was going to ask if i could just use the files that are sitting in my HWOUC folder already, but you beat me to that question. so i should just move that over to my sd card into a temp folder along with that hurupdater app?

Ouch...this locks the bootloader....so can't get twrp or SU back on without losing my data (well, i have a backup, but would have to restore everything, at least i assume) if i unlock the bootloader
If it's stock firmware it will. Forget that download from firmware Finder

Well, it was too late anyway, so the OTA files that were existing on my phone for B376 did flash fine, but now I lost TWRP and root. Beyond that, B377 tried to install today, and even though now my phone is back to factory (i assume, since those changes had been made) Now it fails on the next update of B377 on the EMUI recovery screen and tells me "software install failed get help from http://www.emui.com/emotiondownload.......
Am I stuck now using your method above for each and every OTA update that comes through? If so, how would that be possible since I am unable to get TWRP back onto my phone.

Just reflash TWRP. It should flash fine. And yes, if you plan on using EMUI 8 the above mentioned method is the only way to update. Normally I would recommend you to Ditch EMUI and install a custom ROM. There are a lot of great ROM available for our device. If you want to flash one I will be more than happy to guide you.

Well, I am still on EMUI 5 right now. I was kind of hoping not to go through flashing a custom ROM since I went through doing that on my LG nexus 5, and yes, it was great once it worked, it was a real pain to get to that working part. I was hoping the standard OTAs were going to get me up to android 8, and then just be happy with that. So I am unsure how I can flash TWRP again since my bootloader is locked again. Basically if I am going to be stuck wiping my phone out again, then I suppose I would be inclined to going the route of a custom ROM. So I guess it is just a matter of if I can get twrp on here again without wiping my phone again (unlocking the bootloader)
Um, no. You can't get TWRP with a locked bootloader. And also you can't go from EMUI 5 to 8 via Hurupdater. In Oreo partition table changes and Hurupdater can't flash that. So you will have to upgrade to Oreo manually. You can easily do that. It will take an hour to get to Oreo as well as flashing a ROM.

so in essence what you are saying is that I can't go any further at all right now without wiping my phone again so i can unlock the bootloader? As of right now, I don't even know Huawei is going to release Oreo for this phone OTA, and even if it does, right now I can't get it. So since you have been so helpful (and very much appreciate it btw) what do you think is my best course? I don't think unlocking the bootloader will be an issue. i have the code saved somewhere around here. I wasn't all dead set on EMUI, it was just kind of nice staying somewhat in the realm of legit. And no, I have no qualms about straying outside of that. I just didn't want the nightmare I had with my nexus occurring again and not having use of my phone as a phone for the longest time. I'll await to see what you think I should do. Thanx again
Well. Flashing is easy. I'd recommend you to unlock your bootloader. And after that download HWOTA from thread. I will provide link. Next I want you to decide that wether you want stock EMUI 8 or want to flash a custom ROM. Depending on that I would advise you to either get Indian or Chinese EMUI 8. Indian is good for daily driver. Chinese for flashing custom ROM

Looks like I will be stuck either way with wiping the phone, so I may as well go the custom ROM road. Don't really need to bother with the HwOTA then I wouldn't think. Unless I am missing something here. So who are the players for custom these days? still cyanogen? I saw on a search thay had android oreo 8.1. I used their custom ROM on my nexus as well. I most likely won't be getting to this now until tomorrow. I'll backup my phone...oh ****, titanium isn't gonna work. no more root....ok, i'll unlock bootloader, get twrp and root back on my phone and backup so definitely not until tomorrow. Only question for tonight is do I still need that HwOTA? I think I am a bit confused on what exactly I am trying to achieve. is it EMUI 8 with custom ROM of android 8? or nixing EMUI completely. Pardon my ignorance, but I really am just a bit hazy here on how this all works. all this for some stupid security update only because I thought it would open my phone back up to getting the OTAs and Huawei would release 8.....
Well. Since you are on EMUI 5 you will have to use HWOTA once you get to EMUI 8 as all custom ROMs require that. It also adds Project Treble support. So you will be flashing EMUI 8 once. After that, it's your choice. Either stay in stock or take the custom road. In terms of stock, there are currently 3 Android 8.1 ROMs available by OpenKirin and one Pie ROM available by Askuccio Droid. OpenKirin ROMs have stock camera in built while Pie ROM is.... Well Android Pie. All of them are smooth, have tweaks and great battery life and are infinitely better than stock EMUI 8. If you want the stock road, upgrade to BLN-AL20. That's the Chinese EMUI 8 and better for custom ROM. If you want stock EMUI 8 then go for BLN-L22.

Ok, I must just be really tired. Is there not some way for me to just get back to whatever is causing this next OTA to stop? Meaning even though it is just some stupid piddly update, just get my phone to accept that without going totally overboard and what seems to be a bit above what I know how to do. That way the OTAs will just come at their own pace and I'll live with not having all the bells and whistles. Just going back to stock sort of thing. That is kind of what I thought was going to happen when you so very graciously and successfully got that last update to work. That way I can try something new and just be patient until Huawei forces out android 8 on their own.

So you want to remain on stock EMUI 5? Well it's your choice. Anyway check a few things.
1. Is your bootloader locked? Do you get a warning screen when phone turns on?
2. Do you have TWRP recovery? Or stock?
3. Lastly is your phone rooted?
If your bootloader is locked, you have stock recovery and your phone isn't rooted, then congratulations. You are on stock EMUI 5 and you should receive OTA normally. Or at least I hope so.

2. Do you have TWRP recovery? Or stock? NO, I don't have TWRP anymore

I am not trying to do anything. The phone has received an OTA update, B377, and after it downloads, it says install. click to restart now. After restarting to do the install (the everyday, normal OTA update method, nothing fancy) then it goes to that error. Only option from that black EMUI screen is "reboot now"

Any USA Mate 9 users on EMUI 9 / Pie 9?

Wondering if we will still see the 9.1 update here in the US....
Thanks. Upgrading to 9.1 is what I am thinking about. But after many failed tries, I gave up, for now.
Still on 8.x, and no sign of 9.x.
No help from query made to Huawei USA.
Same here, Oreo 8.0 with B377. Nothing in FF either
Had Live Chat with Huawei USA re this, and in summary the answer was ..."if and when the update is released, it will be uploaded to your phone automatically.".
The operative phrase being "...if and when...".
Sadly, I don't see it happening. With each day, the tension between Huawei and the U.S., now the rest of the world, I don't see anything further from them, for the 9, which is why I went with a different phone in November. After the Mate2, 8, 9 I was looking forward to more Huawei phones, but, with dropped support for the U.S. (rightly so), I had to move on.
Great phones, but without DIRECT OEM support for a U.S. model, I'm just not into the whole root, unlock, flash stuff anymore.
If it doesn't come from the OEM, I don't bother with it. Just gettin' too old....now get off my lawn!
I pretty much agree, except Google and Android bowing to the ban pressure, causes me to rethink not only future Huawei products ( “...if, and when they become available in the USA”), but also Android and Google. I have avoided the dark side (Apple) till now, but am rethinking that..
OnePlus has a good reputation. But in older models I read about higher radiation emissions than other peer phones at that time.
I am thinking of having it once my mate 9 dies...

I won't go *that* dark, as I can't ever imagine owning Apple. It's tricky because I want this phone, just upgraded. I'm all in on Google, just can't find a great phone at a decent (sub $500) price...
EMUI 9 Pie 9 available according to firmware finder
MHA-LGRP2-OVS 9.1.0.252 FullOTA-MF dated 7/17/2019 available according to FF for MHA-L29C567
I just bought a OnePlus 6t and it's has 8gb ram yada yada and really zippy. I like the mate 9 more. The screen on the mate is nice and bright and the sound quality from the headphones blows away the 1+. I even rooted the 1+ and increased the headphones to 90 but still quality is not as good. I like the volume and power on the same side of the mate. I'm desperately trying to figure out how to get pie on it. I'm going to post a question about what files are out there I can flash. I've tried and failed so far.
It's been a while since anyone asked: is there any way to get C567 to 9.0/9.1?
I'm at MHA-L29 8.0.0.360(C567) --never bothered to get to the latest Oreo 377 (doubt that has an effect as I've been going for the FullOTA-MF).
Today I tried firmware finder erecovery and patched hisuite on numerous 9.0 and 9.1 firmwares that were supposedly approved for my IMEI. I haven't tried rebranding, dload method (don't even know if that exists for C567 Pie), or emuiflasher.
Anyone been able to do it?
(I confess I've posted this same question two a couple of other threads here on XDA).
I also keep trying and ran across this article and says to use flashy to manually flash the 2 beta files for 9.0 way back in january. I wonder if I can use the flashy tool to flash the current 9.0 432 files for now and let those update to 9.1 when it happens. Had I seen this article way back in January I would have tried it. You can use the second link to download any version of android for the mate 9. Type "mha-L29" into the search field where it says "enter model" and press enter. Then just left click on the "filelist" and a second later it will pop up. The cut and past the url into a new window and press enter and it will start downloading. If the beta files will work with flashy then why not the actual files. In xda the p20 forum has similar instruction for beta pie back in 2018.

Edit: Someone did the exact thing I was thinking about with the p10. He used ff to download the actual files and used flashy. Maybe I'll give it a shot earlier tomorrow. I'm not sure how to use flashy yet though. It says unzip the update files into the unzipped flashy folder but not sure where in the folder. I guess I can try and see.

Nice find jeffrimerman! Looking around, I found the original developer of the beta flashy tool is @a1Pha, who designed it for the P20 Pro. Here's his OP on the method:
https://forum.xda-developers.com/hu...uide-how-to-install-emui-9-android-9-t3839316
I read thru the 45 pages of comments in that thread and saw a couple of folks that had successfully used the tool to upgrade from Oreo to Pie and rebrand at the same time. Also a couple of folks who used it on other Huawei models. The tool requires two zip files, so I think you're right about needing to upgrade to 9.0 first (as 9.1 has a single zip file).
Quite a bit of discussion in the thread relates to maintaining bootloader and FRP open. It seems we might end up with those locked, making it difficult to change/upgrade ROMs other than by OTA. That would mean that under the worst scenario (other than some unexpected bootloop), we might get stuck on that 9.0 ROM if for some reason Huawei checks IMEI and not region for upgrades. The thread also has a post (linked in the OP) that has a modified FLASH.txt file to use to upgrade from "Beta to Beta" and another for getting back to Oreo, so even this scenario might be avoided.
As for where to put the zip files, the beta-flash_0.2.zip, once unpacked, has a folder conveniently labeled "ZIPS-HERE"!
I'm currently downloading MHA-L29 9.0.1.191(C432E7R1P8) from FF, and will wait to hear from your test to give it a shot! Good luck, and I'll help anyway I can if something goes south. :good:

Opening the FLASH.bat in beta-flashy, I noticed it installs a custom "No Check" recovery. It probably has a "secret sauce" in it, so it's probably required to use the one for the P20 Pro that's in the original tool. For a moment I thought of replacing it with the "No Check" recovery for MHA specifically in the HWOTA8 tool (also by @mankindtw but slightly different file size), but best not to tinker too much?
https://forum.xda-developers.com/mate-9/how-to/guide-mate-9-flash-oreo-update-package-t3699522
https://www.dropbox.com/s/11ghma7pqkbq32h/MHA_RECOVERY8_NoCheck.img?dl=0
Oh wow, I actually PM'd him last night asking about exactly how to use the tool. I tried downloading from his link on that post but it didn't work. I did see the zips here so I'm sure you're right on that. The article I posted here mentioned unzipping the updates so that's what confused me. I'll have to read that guys post and see if he mentions it. Maybe he'll respond to my pm before I attempt it. He also flashed a beta 9.0 and wasn't sure if updates would come ota after that so maybe he'll know by now since it's been months. If I don't get a response then I'll ask in his thread. Has 9.0 been able to be rooted? I have my unlock code still so I can redo that from adb if I need to.
I didn't have any trouble downloading the beta flashy, but just in case, here's a copy:
https://www.dropbox.com/s/te9fcilkphi7n7i/beta-flashy_0.2.zip?dl=0
I'm not that concerned about further updates once we're on 9.0 C432, for example to 9.1. There seem to be multiple options in case OTA doesn't work: using the beta-flashy with the "beta to beta" modified script, using the EMUIFlasher_1.2.apk (intended for OpenKirin, but apparently useful for rom changes within Oreo or within Pie--but not between them), the FF eRecovery method, modified HiSuite (probably the best option as I believe it doesn't require root, unlocked bootloader or data wipe), or perhaps HWOTA9:
https://forum.xda-developers.com/mate-9/how-to/emui-9-0-beta-t3857239/page18
Let me know if you decide to pull the trigger! I'm tempted to give it a shot too.

Regarding root on 9.0/9.1, it seems patching recovery with Magisk is working, although with some hiccups especially in 9.1 (stock phone app crashes):
9.0: https://forum.xda-developers.com/mate-10/how-to/guide-magisk-root-mate-10-pro-t3886967
9.1: https://forum.xda-developers.com/hu...nt/guide-magisk-root-p30-pro-bl-code-t3938285
Note that having bootloader unlock is indispensable for root. Glad I got it back in the day!
I've got the files, same ones you downloaded. The guy that updated with flashy on his mate 10 back in Jan couldn't remember exactly what he did.
"Download the firmware and extract it inside the same flashing tool extracted area" - This is from the article so it sounds like extract them into the "zips here" but then they technically wouldn't be zips so makes me wonder.
"Extract the firmware bundle, you'll get two ZIPs and some XMLs." - Tool creator says something similar but he said you end up with 2 zips but he was talking about 1 beta file which might have bundled the 2 updates together which makes me think I just put "update" and "update full yada yada" into the zips here folder.
I'm noticing if I unzip both files they both have a "META-INF" folder which could cause some confusion so it makes me think do not unzip the updates. I think tonight I'll end up trying it with the updates being zipped.
I think I'm on page 10 of the post of the p20 with the tool and one guy mentioned renaming the zips. I'll have to read and see if we need to rename them. Did you notice anything?
This was some instructions I read in a "flash.txt" file I read for using the tool to downgrade so I imagine we need to do the same to upgrade. Same name for the HuRupdater also. I think I have all the info I need
echo.
echo Put the update.zip into the "ZIPS-HERE" folder.
echo.
pause
echo.
echo Now rename the update_full_XXXXXX_hw_eu.zip to update_all_hw.zip and put it in the ZIPS-HERE folder.
echo.
pause
echo.
I assumed you would rename the zips and put them in the folder "ZIPS-HERE" without extracting the contents.
I was thinking the same thing but since both literally said extract I didn't want a brick =( hehe. I did it!!! I put the whole folder and ran it from the C root of the drive just to be safe. I thought someone mentioned it not seeing files. I followed the instructions that show on the pc in cmd promt since it pops up a cmd window and guides you through. It seem to do it smoothly then the phone boots and you have EMUI with the circle loading the file to 100%. When I hit 100% it said "update failed" and gave me one uption to reboot. I was worried I had a brick. When it rebooted a different Huawei logo came up and said "optimizing apps" and got up to 100% and booted up fine. Phone looked exactly the same which worried me. I never did a factory reset so it literally did a normal update and kept all my settings and icons the same and I never had to input anything. I checked phone info and it's build number is 9.0.1.191(C432E7), with emui verson 9.01. Success!!!!! Security patch says May 5 2019. I imagine we'll get a regular update when 9.1 rolls out to us or you can probably put resurrection remix if you want. I put that on my Xiaomi Mi 8 Lite and it's pretty nice. So far so good. My bootloader must still be unlocked since it gave me that warning. Even developer options is still there. Enable OEM unlock is checked but not greyed out so I can still lock maybe. Let me know if you have any questions.
Edit: This helped get hotspot working again
Connection your phone to the computer (may need to enable developer settings)
adb shell settings get global tether_dun_required
If the result is "null" or "1"
adb shell settings put global tether_dun_required 0
Reboot phone
So, I gave it a shot as well. All went as you described, except I didn't get to the "optimizing apps". Instead it bootlooped about 3 times and then told me there had been a problem and that it suggested a factory reset. Must have been some root app or setting after all these years that tripped the process. Anyway, I was able to then get back to a clean 9.0.1 C432 and luckily I had done a full backup to external storage with the Huawei app. I restored, had to tinker with some apps that didn't get all their settings updated and reenter my Google password, etc. but am back in business in Pie!
I did try to go ahead and update to 9.1 via FF eRecovery and modded HiSuite to no avail. Also, the phone keeps wanting to "update" me to the same firmware by installing a 20kb OTA claiming I have some unauthorized apps (even right after factory reset). So I'm a bit suspicious that I won't be getting OTA to 9.1.
Next step will be to root (I've got several apps that require it), and perhaps try the 9.1 update via EMUIFlasher or some other method in a couple of weeks if I don't get an OTA push.
Thanks for getting my courage up and working on this together. Let's keep this thread active with any updates from either of us. Hopefully this will also help other C567 Mate 9 users get to Pie.

Succeeded in rooting with Magisk:
Magisk Manager apk in OP: https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
Instructions for EMUI 9: https://topjohnwu.github.io/Magisk/install.html
That's great news, we're 2 for 2. I had Viper4Android which I never got working, magisk, root checker but not really that many root apps so maybe that helped. I wonder if we can use this same method to get to 9.1 or is that just 1 file now. I think this tool is written for 2 files, not 3 and not 1. I wonder if the "dload" method would work. I could never get the big update.app file onto my sd card. It would always fail but maybe I need to reformat it from exfat to ntfs or something. Welcome to PIE =)

Bootloader Unlocking through Downgrade possible?

Hello Guys,
i had bought an Huawei P20 about an year ago. Now you know with all of this "USA-Huawei" Trouble going on, the thought came to my mind that i better start unlocking bootloader and be prepared to flash custom rom if worst come to worst. so far, so good.
now i started looking around if there is an easy method of getting the bootloader unlocked. but oh my, the huawei company is very friendly to us users and say "no, you wont get any unlock code from us anymore". so screw that.
now i want to try some experimental stuff. it looks like this:
my Smartphone has currently the version EML-L29 8.1.0.168(C432). I bought some Credits (i think it is that thing for $4) from DC-Unlocker. Yeah yeah i know, there they say "no support for Huawei P20!!!". But i still want to try. Well i tried, but it doesnt work - what you should expect.
now i read from some other website that there is another way of unlocking it. i only read it diagonal but the one thing i read was the information "unlocking bootloader is only possible till firmware version june 2018". so i jumped to an maaybe interesting conclusion about unlocking the phone with DC-Unlocker or HCU (whatever, i guess maybe both use the same method anyway).
if i do an rollback to the old firmware version *before* June 2018 on the device, wouldnt it be possible to do the unlock? Because the security patches that preventing it unlocked arent on the device then.
So what i have done so far is loading the old firmware version 8.1.0.128(C432). But the source is saying that it is coming from "Asia" but in the next line it reads "Asia, Europe" etc. - do they mean that this version is universal or do i run in trouble if i install one that is having the wrong area?
the next thing that kinda baffles me... all guides are sayin "copy the extracted dload folder to your sd-card". even the p20 guides do that. but.. well you know, the p20 device doesnt even have sd-card support. so how are you intended to use it then? i wonder about that a bit.
i dont think that without unlocked bootloader, flashing an original OTA full update would be impossible. but im not really sure how. there is this shady menu you can reach if you call this strange numbercode. but im very unsure if that will really work out. the phone (it is still a phone without SD-Card-Support) even has the option "apply update from sd-card". so im wondering how this feature they implemented in the original software is intended to use at all. maybe i should push the dload folder on the internal storage? i dunno.
i read about another possibilty of flashing stock roms. they say you can do it per adb command. so no problems would be here, i have adb and the hisuite and all already set. but i have absolutely no idea if that is possible without unlocked bootloader. so the questions arose from my mind are those:
- does an stock rom image from possibly/maybe asia would do any harm to my device like it is getting unbootable or anything like that?
- is it possible to flash an image older android stock rom with methods like this special menu on the device or the adb load?
- do you all think that my plan of downgrading the phone in order to get the bootloader code would work?
i'm looking very forward to your answers )

No. Sorry. There's no solution. Reason: It would appear in this forum within minutes and thousands of people would be happy to unlock their bootloaders. Many Huawei-Owners here on XDA invested a lot of brain power to find a way. Noone succeeded. No bootloader code, no unlock.
If you still want to play around with firmwares, please inform us about any progress.

okay so there are basically no real information. look, i dont expect anyone to say like "oh there is an easy method xy" because i know it doesnt exist on this moment in time.
however i made an percent of an progress, it is more a thing for other interested custom rom modders out there.
i downloaded this update.zip and there are all kinds of howtos on the internet about it. the one thing i did is basically create the dload folder. then i put the extracted update.app in there. i rebooted the phone with power, vol down + vol up. i released the power button after the vibrating. the flashing screen indeed appeared! but something very strange has happened and i have no explanation what have happend.
so the emui updater appeared. there was this emui logo in the middle, the circle building up around it. but then it stopped at 5%. i really got panicked that im about to brick my device. so in an mad attempt i wanted to stop the update and power off the phone. glad i didnt do it. the phone always said if i tried to press the power button long enough "the system will crash if it is powered down". i stopped - but i tried it serveral times to stop.
now the strange thing is.. it stuck relatively long on this screen. but after a while (i guess it was 5-6 minutes) it suddenly got dark. and the battery was at 100%, so it wasnt a faulty battery. i just wondered. the phone - other than i would expect - rebooted. after a short while of the logo flashing (for about an half minute) it finally started. first i didnt have any connect to GSM Network. but after a short while that was okay too. all apps are still there. i looked at "about" and the version is still the same as before.
do someone have any imagination what has happened there? so apparently the phone *does* try to install something on this method, but the method seemed to fail. or is there any knowledge out yet for update logs that are getting generated by this process? i try to find any hint in order to tackle this problem atm.
and one thing is still on my mind.. could it be that the update is already through and i just didnt realized it yet because these other custom files werent changed? i mean that could be an possibility to say the least. anyway, i will try to use hcu now if maybe sth has changed. and i give kingoroot as well a shot if this buddy finds everything about rooting the device. maybe with root rights through exploit i can get further.

It seems you have a couple of questions, pal, I answered to the first one (Bootloader Unlocking through Downgrade possible?). All I said is that it's impossible to unlock the bootloader through a downgrade. If you read all the how-to's you should have noticed that FirmwareFinder doesn'st work anymore since EMUI 9.0. This Information simply means Huawei doesn't allow us to flash updates on our own anymore like we did before. For sure there are some guides how to rollback to Android 8 but even this changes nothing to the bootloader.
Sadly I have no answer to the other questions about the strange behavior, it sounds pretty odd. Never heared something like this. But good luck fixing your phone anyway.
well i found out a couple of things now.
first thing: you know the service menu when you try to apply a zip archive from sd card? well you wont be able to use it UNTIL you use an usb-otg cable and an exFat formatted USB-Stick. Next thing to know is, you have to use the right images. there seem to be an kind of rule how this images are supposed to be and the image i found was from an russian firmware download site it was linked here in the forum in a thread. so i did choose "apply zip from sdcard" and .. IT DOES! the device rebooted, the stick flashed and the flashing process occured! and guys, im back to Version EML-L29 8.1.0.128(C432)! it is clearly stated in the build version view in settings. so.. i guess you *can* roll back even without firmware updater.
so far so good. but lets get back to the problem with the Bootloader. sadly Jan Philipp was totally right.. the bootloader cant be unlocked even in this version with the security patch of 5. may 2018. that is kinda sad. even kingoroot is still no different from before. i guess i have to search now for an way to get the system rooted. however, it must be easier on an earlier security update stage like now instead of the future versions of emui 8.1.
edit: another strange thing i discovered so far is that after this restore.. the play store wasnt able to connect to the google server until i gave permission to a few google processes to calendar and file access (i wonder what that is all about). maybe it has something to do with incompatibilities in the rom versions but now it works just fine as it should).
"unlocking bootloader with exploit is only possible till firmware version june/july 2018" does not apply to 2018's devices with kirin970, kirin980 & kirin710.
You are with kirin970.
So to unlock your kirin970, the only way for now is to wait for 3rd party seller to hypotheticaly start back their dervice:
- In the last 6 months there was only 2 'windows' which lasted 3 or 4 days where you could order your bootloader's unlock code by imei (from 5 to 124 us$).

Google Play services require all permissions, otherwise won't work.
I also been searching on how to unlock the bootloader and found no solution or hope. I guess we are stuck with EMUI forever.
Reply from Huawei:
You can roll back to earlier versions of EMUI software, but you have to roll back one version at a time. However, our earlier phones operate exclusively on Google Mobile Services so removing it would limit the functionality extremely, however, we do have a range of new devices that no longer rely on Google Mobile Services and use Huawei Mobile Services instead - such as our P40 series.
Here are the instructions for rolling back software:
[Rollback Guideline] EMUI 9.1 (Android 9) Rollback to EMUI 9.0 (Android 9) Operation Instruction
EMUI 9.1 (Android 9) can now be rolled back to the official version of EMUI 9.0 (Android 9) using HiSuite, without downloading any intermediate packages. To ensure that the rollback succeeds, read the instructions carefully and perform the steps as instructed.
1. The following are precautions for roll-back.
a. Rolling back to an earlier version will erase all data on your device. Use an SD card, computer, or Cloud storage to back up all important data before rolling back your phone, and make sure all backed up content is complete and effective.
b. Use a computer running a Windows operating system to visit http://consumer.huawei.com/minisite/HiSuite_en/index.html and download the latest version of HiSuite. If HiSuite is installed on your computer, click the version number in the lower left corner of the page to check if it is the latest version. Make sure HiSuite version is 9.1.0.303 _OVE or above.
c. Before rolling back the phone, make sure your phone has not been upgraded using non-official updates. Otherwise, the roll-back may fail and unknown issues may be introduced. If you have used non-official packages to upgrade your phone, it is recommended that you go to an after-sales service center to roll back your phone.
d. Before rolling back your phone, make sure that your phone system has not been unlocked or rooted. If the system has been unlocked or rooted, it is recommended that you go to an after-sales service center to roll back your phone.
e. Before the roll-back, restore the phone to factory settings to make sure there is enough storage space.
f. Make sure the battery level is more than 50%.
