Downgrade Huawei Mediapad M3 (China) from nougat to Marshmellow - Huawei Mediapad M3 Questions & Answers

Hi XDA peeps,
I have recently brought a Huawei Mediapad M3 and i love it, but i would like to downgrade it so I can root it afterwards. Why downgrade? Because the on the official website where you're supposed to unlock the bootloader. You need to select whether the tablet is EMUI4/4.1 or EMUI 5. Because I have Nougat I do have EMUI 5, I need to select EMUI 5 on the website. However I can't set the category on "tablet", only "smartphone". It will ask for a IMEI/MEID number, which I dont have... You can select "tablet" only if I had EMUI4/4.1..

pic2: (replace https here ) puu.sh/xgE2j/01998bb7ed.png
I was wondering if its possible to downgrade the M3(CN) to marshmellow. I saw there where tools available to downgrade for the US(Sorry, no US, my bad) and Eu version, but not for the chinese version. Does anyone know how to downgrade the M3? Or maybe a other way to unlock the bootloader, so i can install TWRP? I'd like to install a different rom.
Any other suggestions are welcome too!

I'm looking to downgrade the US version. Could you share where you found the tools to downgrade the US version? I've only been able to find rollback for the EU version.

I'd swear i'd found a roll back for US, but it seems it doesn't exist. Otherwise you'd be able to download it from the official Huawei website. Sorry man.

You need to install Huawei tablet software (can't remember the name) on your pc and in there it will give you an option to rollback. That's what I had to do, to downgrade.

You are the man! I installed HiSuite and it gave me the option to upgrade the firmware OR to downgrade to version Android 6.0 with EMUI 4.1.3(Chinese version). I've successfully got the unlock bootloader code from the huawei site. Going to install TWRP soon.. Thanks again!

*If you follow these instructions, do so at your own risk. I had success with it, I am not responsible for anything that might happen*
At this point, I could retrieve bootloader code from the huawei website and unlocked the tablet with these instructions: http://www.stechguide.com/unlock-bootloader-of-huawei-devices/
Installed ONLY twrp: https://forum.xda-developers.com/mediapad-m3/development/twrp-greatslon-mod-t3489232
Used "Firmware finder rewrite" to find the correct firmware. My case i wanted to flash to C100(EU): https://puu.sh/yjdFb/a295fb3207.png
Uploaded the zip files to the SD card, rebooted the tablet in TWRP(complete shutdown tablet, no cable connected, hold up and power button till screen turns on).
install update.zip then put the other zip in the queue. Install and reboot, enjoy.
It does not look like it comes with google play, browser or any bloatware(it dint work).
Since I now have EMUI 5, i needed to download twrp specially for emui 5.
Had some problems with not being able to open google play or gmail. I reinstalled the rom with this one: http://www.stechguide.com/huawei-mediapad-m3-b303-nougat-firmware/, cleared dalvik cache and set timezone in TWRP. After flashing the rom, did a factory reset. Now google play services work! Happy days

[PLK-UL00] Official ROM B352

Hello
I've managed to download an update for B201 to MM B352, using a Chinese proxy.
If anyone wants to play with it, just download it from here:
https://mega.nz/#!wwMTFTjS!1z9xygbiNTO66_zkwxOHtw9SLI_EQVTRzUZU-kh2BSo
Save it on internal storage or SD and go to Settings -> Updater -> Menu -> Local Update to apply it.
This is *not* an update to be applied using TWRP or 3btn method.
When I installed it my phone was using stock recovery, bootloader was unlocked and it was not rooted.
After installing it everything works fine, TWRP works fine, but it will stop working after installing SuperSU.
Not sure why.
So, right now, I'm back to Lollipop B201, which is geat.
UPDATE: using SYSTEMLESS install for SuperSU I was able to install it.
Now I have everything working, including notifications.
Regards.

Yes, I have the same problem, but after installing SuperSU
You have to use fastboot mode and run multi-tool unbrick method.
I have stock rom, with stock recovery. How can i do? How can put the Phone in fastboot mode?
i'm still blocked from that day. with a phone that doesn't go in fastboot and remain with the honor logo.

Is this *REALLY* meant for UL-00?
Hi there
Efforts much appreciated mate ...
Looking at all the bootlooped replies - is this firmware *really* meant for the PLK UL-00 (India version)?
OTA doesn't show any B352; nor does the official websites... B341 seems to be the latest firmware for the Indian variant.
So .... Just wondering - is it some typo ? Is this meant for some other variant of Honor 7 ? CL-00 maybe? ... Even the older B201 you have mentioned in the OP - isn't among the firmware builds that the Indian UL-00 has come through... i think.
--
Would be nice to see some changelog or a screenshot or something
--
If it is a typo error, please do change it in the title.
Hi
There are two variants of version UL00, C17 from China and C675 from India.
I have the one from China, it's dual SIM.

Hey I have got the Indian Version B341. I just wanted to share a problem that I am facing.
My phone is slow charging due to update perhaps. Earlier the phone used to charge really fast now it takes more than 2 hours and sometimes even close to 3 hours.
I have tried Hardware Reset but was not of much help.
Has anyone solved this problem. Btw I am using 5V2A charger, supplied with the device, which took very little time to charge earlier. And also when the phone is switched off it charges really fast but the phone heats up a lot.

Right...
The firmware in the phones we got (the single SIM Indian variant of UL00) does indeed say C675 - I just checked after your screen shot.

So, i am still wondering - is this firmware gonna brick the C675 single sim variant?
Replace PLK-UL00 Chinees version with PLK-L01 EU version
Hi,
did anyone try to replace the PLK-UL00 Chinese version with PLK-L01 EU version, is this possible without bricking the phone ?
I have rooted my PLK-UL00C17 (Dual SIM) with TWRP 3.0.2.0 Recovery for PLANK, running build PLK-UL00_6.5.16 from 1 May 2016, Titanium Backup and SuperSU Free v2.62
I tried to get rid of the Chinese stuff, but no luck, it keeps popping up everywhere.
So is it possible to replace the Chinese firmware / ROM with the EU firmware / ROM ?
Thanks,
This update bootlooped my phone and now I can't fix it.. £200 paperweight now

Move this app to "dload" folder on SD card and local update.
Other step - update via three buttons (or projectmenu) , but erase data and relock bootloader.

This is list of vendors. Change via TWRP.
1. Flash location zip
2.Flash firmware zip
3.Reboot and factory reset
This is to get ММ . After you can flash Nougat also via TWRP , or get OTA.

Have P9 VNS-DL00C17B245
Hello friends, I Have Huawei P9 VNS-DL00C17B245. This Chinese version phone is a big headache.
I have VNS-L23 and it is everything I need and want. So I bought another one for my wife. But this guy sent me the wrong phone. And it is expensive to ship, to where I live.
I have flashed ROMS to SAMSUNG before. Quite simple.
Is it possible to flash same as VNS-L23 to the VNS-DL00C17B245? If not, please advise me how to put the correct software on a Huawei.
P.s. SD card reader not working on this phone and neither is sim slot 2, which are the same spots. I imagine Huawei disabled this for China. I thought I read something about this somewhere. You probably tell I have been at this for three days.
Help me please.
Have P9 VNS-DL00C17B245
I already posted here, but no response. I have ADB, TWRP and and phone is rooted. I want to put EMUI 5 with Android 7. Is it possible, how to do it? I am five days on same phone, full days, I tried everything, I read everywhere. I want to throw the phone against the wall now.
It is a P9 VNS-DL00C17B245 but on the back cover it says VNS-AL00.
The SD card reader is not working and also the SIM SLOT 2, which is the same slot as the SD Card Reader.
I received the phone like this, after purchasing it full price, and had it sent. Was meant to arrive a VNS-L23 but the seller was a mother ****er. And I bought it via my sister in the USA, and I live in Venezuela. I am stuck with this piece of ****. I really need any help I can get,
thank you!

here is how update honor v9 to oreo B331
on your phone update Hicare app, open it, from member tab login with your HUAWEI ID(you could easily create one if you do not have) then from service tab click update after application successful message, you could update the phone from system update.
According to the app firmware finder from 8/1 the Oreo version is out. Seems that B335 is the official. Last time I remember, after seeing it there, the upgrade was OTA within 10 days. I think that's great news.
I'm on B335 and I'm having issues with google service especially with location sync.
- Location history is disabled and I can't turn it back on in the google maps setting
- Find my device is not reporting location
I factory reset my phone, disconnected/reconnected my google account and it's still working. I'm hoping that this is not the official release because otherwise I would have to revert back to EMUI 5.1.
How did you got it? OTA or did you forced it? Since yesterday 29/1 firmware finder does not appear the b335 !

b340
Hi, I'm having the B336 official Rom and I've seen from huawei's app FirmwareFinder that there is an upgrade up to B340 (at the moment). However if I try to upgrade my phone through this app I get a " firmware not approved for instalation" when I check comparability with IMEI. Is it only me ? Anyone else having same issue? If I check for system update I don't get any update.

the error you got, is , because of imei check failed. When I use the app FirmwareFinder, I do a imei check comparability, if i get the green light, it is to update. But ever since I got B336, I dont get any comparable firmware and already there is out, the B341 rom. I just wonder when will we get it?

Get unlock code for BTV-W09

Hi, I have been reading threads on how to unlock my mediapad 3 (BTV-W09). I wanted to know if anyone with the same model who succefully got his code could tell me how to put the information. I have tryed "BTV-W09", "HUAWEI BTV-W09", etc. with no luck, i always get the msg "Please make sure the information you entered is correct." I have tested firefox, edge, chrome, dolphin, etc.

I've run into the same issue. I don't think it's the correct message. It should say something like "Please notice, we don't provide unlock codes for your device."
I wrote Huawei support and this is the message I got back.

Same result here
I got the same problem on the unlock web page, and the same email result from Huawei USA.
I finally resorted to paying the $4.49 to DC-Unlocker and successfully unlocked (rooted, installed TWRP, etc.). I *have* read here and there that Huawei requires that you create an account on their site and log into it for some period (I want to say 14 days). I didn't have the patience to try that route, since I wanted to get the device set up and not worry about having to wipe it again in two weeks' time.
[Edit] I did open the special configuration menu (with calculator in landscape mode and a special code I can't remember just now: someting like "()()824579()()="). There, I found a model number "BTV_W09_V2" (note the underscores). Once or twice in my dozens of code-retrieval attempts, this model number gave me a response on the website telling me that my unlock code is "{}". It felt like progress, but was still useless.
Were you guys on EMUI 4 or 5?
I had to downgrade mine to EMUI 4, get the unlock code, unlock it for the first time, adb flash TWRP then upgrade back to EMUI 5, use back the same unlock code to unlock the bootloader again. Once updated to EMUI 5, remember to adb flash TWRP for EMUI 5.
I finally got my unlock code, i wrote an email last week asking for the code on the contact form (http://consumer.huawei.com/en/contact-us/?tag=email). After two or three emails moving me from one department to another, the gave me the code.
Thanks. I used dcunlocker on two BTV-W09C128B005 tablets and it worked (8 credits). You have to use the calculator and sub *# with (). Received the same email that says you will brick the device and they don't supply codes, bunch of lies. I also got xposed (think v23) in fine after greatsalon's w09 version of twrp and latest su. Removed the updater and all the other garbage services they use to spy, staying on stock marshmallow for now. Apps used to fly drones like litchi don't work well on nougat but are stable on marshmallow.

Updating M3 from B350 to latest fw

My situation is having a C100 MediaPad M3 which I "rebranded" to C128 in order to upgrade earlier to Nougat (here's the full guide I followed) which also included rooting and TWRP custom recovery.
I would ideally like to:
update from B350 to B356 on current C128 (USA) line of updates
OR
rebrand back to C100 (EU) and update to B307 (although I suspect this route will involve downgrading again which is not really ideal).
I have backed up my device with TWRP. My settings app has no system update and my OS build number is "NRDM90M test-keys", which I guess means it's not a general release version.
Anyway, I have a few questions before attempting to update:
1. will updating wipe my data i.e. factory reset?
2. what is the difference between OTA and fullOTA, and does it matter which I flash?
3. will the update work with just the most recent fw (B356), or do I need to flash each update since my fw version (B351, B352, B355 & B356?)
4. do I need to flash all three zip files for each fw?
5. will HuRUpdater be able to update this device and is it a preferable method nowadays?
Thanks

Maybe. It's depends... It's a thing specific to the firmware version you are flashing.
2. what is the difference between OTA and fullOTA, and does it matter which I flash?

Search the forum or the internet, this question is responded 1000 time a day
3. will the update work with just the most recent fw (B356), or do I need to flash each update since my fw version (B351, B352, B355 & B356?)

Of course, these are "parts" of a ROM.

Some people (me too) reported that software working well with this device.

I had been waiting for a while, so thank you for replying @nicolap8.
I'm thinking after a few Google searches that fullOTA is the way to go here and applying each incremental update to my ROM version.
I will also give HuRUpdater a go and see what happens. I'm not planning to do this anytime soon, but I'll update here with my results as and when something happens.

Nonsense: use last Full (311) and you don't need anything else.

I'm on 310 and the only TWRP existing here is working.
It surprise me that doesn't work on 311.

Are you sure this is correct? Remember I'm on a "rebranded" C100 device, with 350 (C128) installed, so the latest for me now appears to be 356.
The latest for BTV-W09C100 on HFF appears to be 308! Where are you guys getting 311 from?

This is the reason to write ever the FULL firmware version
I'm on BTV-DL09C100B311. Updated using HuRUpdater with FULL version downloaded through Firmware Finder for Huawei (all 3 parts).
do we have a 2019 update or has huawei cancelled the device?
