Similar M3 from Amazon.de - updated to Nougat manually

I also got M3 with same firmware BTV-W09C100B007 from Amazon (Germany) this week. Apparently they have taken B006 and just applied newer security patch on it. There is minor difference however in "Custom version" as I have CUSTC100D100

2

.

I find it absolutely unacceptable that still not all variants have Nougat available! It has been released over a year ago and even slow Huawei has released it for majority of the users 5-6 months ago or so. But still this variant doesn't have the update as of today.

I couldn't wait anymore and installed the official Nougat with the help of Firmware Finder by using the DNS hack option so that the update was offered through regular update path in Settings - System Updates. First I installed BTV-W09C100B302 FullOTA build with number 92984 from 15th of June (I'm 95% it was that build). After that I applied BTV-W09C100B302 OTA build with number 90424 from 11th of July to get the latest updates. I'm still behind in security path (5th of May 2017) compared to where I started which sucks and there is no newer version to update to. I guess that's what it is for now then or is it? Anyone with fully legit updated Europe WiFi-only M3 with Nougat?

If anyone follows my footsteps, please keep in mind that your are updating at your own risk.

Hi, I have the UK M3 - WiFi only. Got the official OTA update to android version 7 - Nougat and EMUI 5 on 29th July in the UK.

Now reads as custom version "CUST9C100D002" -

Security Patch May 2017.

Firmware now is build number "BTV-W09C100B302"

I decided not to mess around with firmware update as the thing is so fast and hardly any bloatware, I didn't see much point risking bricking it as apart from not being able to use my library of rooted apps, it does virtually everything I need it for as is.

I have found that contacting Huawei through their HiCare app they have been very helpful and happy to give advice.
[Huawei Mediapad M3 Questions & Answers] tmihai20:
I also have a WiFi only M3 (32 GB internal memory) and I got the OTA to Nougat almost as soon as the others. I went back to MarshMallow when I heard that some users around me got it (geographically speaking) and I got the OTA immediately after connecting it to WiFi.
[Huawei Mediapad M3 Questions & Answers] Chid101:
Hi,

I have exactly the same issue! Ive had my Mediapad around 6 months but received no OTA update. I decided to try and do it myself. I tried Firmware finder, but the only update it found was BTV-W09C209B005, there it seems to have got stuck and finds no further updates.

Has anyone found a solution? Im looking for the same, which file to download and a brief description on how to update to 7.0, as it seems Firmware finder won't work.

Many thanks
[Huawei Mediapad M3 Questions & Answers] 30adi:
You probably need to change region to get the nougat update. Check Huawei site for new updates.
[Huawei Mediapad M3 Questions & Answers] Chid101:
Do you mean change region in Hicare, or flash with a completely different firmware? Is it a simple process and which would you recommend?

If it is the case that C209 is a dead end, probably it's better if I do move to a different firmware, I'm just not sure why, what's described as a "global ROM" hasn't received the OTA update.

I'm what could be said a medium to slightly advanced user, but not experienced in this area and worried to brick my device, so please excuse any stupid questions, simply lack of knowledge.

Thanks
[Huawei Mediapad M3 Questions & Answers] 30adi:
It's not that easy to do. There are a few posts on XDA from members who managed to change region, but I do not advise you to do it because you can brick your device.

Without knowledge can be tricky.

Best firmware to have is the European, C100.

My previously Firmware Finder force updated BTV-W09C100B007 to B302 got an OTA to B303 yesterday. It brought November 6th security patches and EMUI 5.0.1.
[Huawei Mediapad M3 Questions & Answers] trashcooky:
Is that on WiFi only model or 4G?
[Huawei Mediapad M3 Questions & Answers] tmihai20:
Yeah, me too. Mine is the WiFi only, it went to B303D001. I got it via OTA, actually.
[Huawei Mediapad M3 Questions & Answers] 30adi:
Nothing for the 4G version :(
[Huawei Mediapad M3 Questions & Answers] trashcooky:
Nothing on OTA yet on mine. Currently EMUI 5.00 android 7.00 and still B302. Will let you know if and when. I was about 6 weeks behind the last declared OTA's on here last time.
[Huawei Mediapad M3 Questions & Answers] tmihai20:
EMUI is at 5.0.1, Android version is still 7.0. Most likely just a security patch plus some fixes.
[Huawei Mediapad M3 Questions & Answers] AndroidVeGe:
WiFi only.

Not sure if I was clear enough that it came automatically this time, no tools used. The update is not visible in Firmware Finder as of now for this model at least.
[Huawei Mediapad M3 Questions & Answers] gerrya:
I've had the WiFi only model for almost a month and it has yet to upgrade to Android 6.0. is there any rhyme or reason to when they push updates? I contacted them and they sent me a PDF basically saying they roll out OTA's in waves and not to upgrade any other way because it will void the warranty.
[Huawei Mediapad M3 Questions & Answers] trashcooky:
I got exactly the same reply when I contacted them too. I bought my M3 at the start of the year and got the OTA in June. That's WiFi only.
[Huawei Mediapad M3 Questions & Answers] tmihai20:
Funny thing is that Firmware Finder does not show the new update. [MENTION=5431254]gerrya[/MENTION]: you do not even have MarshMallow? I thought all M3 have at least MarshMallow. Maybe you meant Nougat (Android 7.0). It does matter a little where you bought it from. OTA is available based on IMEI and region. If that certain version is not available in your region, it may be the reason you have not received it yet. Also, be aware that if a certain store sells it, it may not get it through official channels. Some vendors do that.
[Huawei Mediapad M3 Questions & Answers] gerrya:
I have 6.0, EMUI 4.1.3, purchased from Newegg in the US almost 1 month ago.
[Huawei Mediapad M3 Questions & Answers] tmihai20:
[MENTION=5431254]gerrya[/MENTION]: Ok, now I see you have the WiFi only version. You should try to contact Huawei US support. You should have gotten by now the update. I think I read about users in the US that got it.

Did you update correctly? In my case I received OTA, but if fails at 15%.

Tried several things but no result. I went to technical service and they weren´t able to update it.

They told me that version B303D001 is wrong and Huawei will send another OTA soon.

Hey guys,

is it normal that in settings -> ram & storage -> ram only 3.7 GB are displayed? When I go in settings to 'About the tablet' it says 4,0 GB. Where does the difference come from? I am on EMUI 5.0.1 and latest security patch level of November.
[Huawei Mediapad M3 Questions & Answers] tmihai20:
Yes, I am sure. I was able to install the full update. I had no issues at all installing the OTA.

Hello İ recently updated my m3 wifi only to b303 here are the ota files

[drive.google.com/folderview?id=1gaxhHWEV_-g3y_rNwzzuOUNQyZGWDEu1]

important this is only for the european variant (c100) with nougat installed and do not flash randomly it is containing 3 files and i dont know in which order to flash.

İ heard the the device must be unrooted and the bootloader be locked (not relocked). Here how i updated :

İ bought it 2 months ago with the firmware c100b012. İ used firmware finder to update to b302 and did a hard reset from the settings menu. Then made a rollback to b006 when it connected to the wirless it found the official nougat update i installed it and after few days i got the new ota.
[Huawei Mediapad M3 Questions & Answers] evilhomura89:
Any possibility of getting the FullOTA?

Can't seem to find these latest update using Huawei Firmware Finder
[Huawei Mediapad M3 Questions & Answers] reneftw:
Having the same problem myself. Didn't find the full Ota anywhere.
[Huawei Mediapad M3 Questions & Answers] gmexdm:
Here's my experience upgrading to EMUI 5.0 from 4.1.3 wiithout root or unlocked bootloader

>recently purchased Mediapad M3 with EMUI 4.1.3, BTV-W09, for xmas

>repeatedly tried to get OTA update for at least a week, never happened within tablet updater nor through HiSuite on Windows

>decided to do a workaround using firmware finder

>download app through Play Store

>find tablet and select Full OTA to B350 (2.46GB? can't remember)

>downloaded via proxy option (change wifi proxy to localhost, set port, and then it gave me the OTA option after checking. instructions in the app but thats the jist of it)

>finishes download, updates no problem, revert my wifi configuration

>then do another update through OTA (since it gave the option after checking updater) to B351

so now i'm fully updated

i will note that i was aware of the bluetooth issues and wifi not using 5ghz band after ugrading

so far, my BT works as it did beforehand. I can connect my headset and use it no problem but for some reason i can't connect my portable speaker (UE Boom 2). But i couldn't connect it before i updated either.

the 5ghz wifi band is not being used but i didn't check before updating if it was being used at all (forgot to test it, sorry!!). And tbh, i'm not even sure if BTV-W09 uses 5ghz either.

lastly, when going to EMUI 4.1.3 to 5.0, the changelog provided by Huawei says you can revert to 4.1.3 at anytime. I haven't done this nor have I figured out how to do it but the option is apparently there and I believe it was worth mentioning.

Hope this post helps you all!!
[Huawei Mediapad M3 Questions & Answers] trashcooky:
Glad you made it safely. Yes the M3 Media pad BTV-W09 should work on 5GHz WiFi. Sounds like your accessory speaker has a problem or if Bluetooth you haven't paired it.
[Huawei Mediapad M3 Questions & Answers] canouille:
I have found why b303 doesn't show on firmware finder. Looking at my proxy logs allowed me to find the correct URL to download. G and g parameter for scanning in firmware finder is different for our device now ( changed from G from 1224 to 2005 and g from to 490 to 1719 ). I've uploaded the new firmware link to the common database in FF.
[Huawei Mediapad M3 Questions & Answers] gerrya:
I did the update after Gmexdm post above. I posted this over on AC:

I went ahead and did the update after Huawei told me it's Google's fault there updates roll out slowly! It went smooth. Couple weird things I've noticed:

1.When I go into a Google Now card then hit back or X out of it, it takes me to a recent app not back to the Google app.

2.Wish when you switch to using the app drawer it would leave your home screens the way they were instead it makes you start over having to add widgets etc.

3.When I added a widget like Gmail it won't let you resize it smaller than it's 3x3 default. I did find a way around that and it was to go into display settings and switch the display size from small to medium then the widget could be made smaller then you could switch back to small and it stays.

Figured I would just post this stuff in case anyone runs into these issues.

Have you had any issues with bluetooth audio as in sounding very low quality ? I follow the same process of updating to 5.0 everything went fine except for whenever I use bluetooth headphones the audio sounds terrible.

Thanks to [MENTION=1420457]canouille[/MENTION] now I've managed to find the latest OTA on Firmware Finder

View attachment 4373223
[Huawei Mediapad M3 Questions & Answers] reneftw:
Thanks man.

Did the update today. Unfortunately, afterwards, my M3 was locked again with no chance to flash twrp recovery. So I had to unlock it and I lost everything. I don't know the reason, I'm curious if this happened to anyone else.
[Huawei Mediapad M3 Questions & Answers] tmihai20:
Yeah, the latest OTA appears on Firmware Finder for Android too, I checked yesterday. It should show up in the PC version, so you can update from an SD card.
[Huawei Mediapad M3 Questions & Answers] chadlouis:
I received mine in the US right after Christmas time with build number BTV-W09C100B006; I've never unlocked it or rooted it. I tried running OTA but it says I'm running the latest. After hastily following a thread on Ministry of Solutions about updating to B350 directly (using dload folder and 3 buttons method), everything seemed to be working fine until (insert sarcastic surprised face) no Bluetooth, no updater and no default keyboard. Luckily, I found instructions on how to roll back to EMUI 4.0 and Marshmallow using files from Huawei's support site. Those steps worked fine for me. Here's my real issue - Now that I rolled back, the past 3 times I've tried the steps in this thread using Firmware Finder (confirmed via "Check Firmware access" passed before running), when the update is finished, I discover (insert legit surprised face) no Bluetooth, no updater and no default keyboard. So I roll it back again back to EMUI 4.0 and MM. I also noticed strangely enough, FF only has B303 listed as the latest update; also, no sign of B009 or B010. I even tried running B302 and I get the same dilemma. My question is - is my system hosed because of the first update I did or am I running FF incorrectly? Should I start with a totally new tablet? Or do I stick with B006 and wait for the OTA in the US? Any feedback is greatly appreciated.
[Huawei Mediapad M3 Questions & Answers] tmihai20:
[MENTION=6178358]chadlouis[/MENTION]: I would say your update did not go well. I did the same thing once with mine. Roll back to MarshMallow, then try using Firmware Finder, it should work flawlessly. The Dload method can only update one zip at a time and all zips (there are 3) must be flashed one after the other. Firmware Finder developer said it should work as intended on MarshMallow, but not on Nougat for some reason. Update to the latest full firmware available on Firmware Finder, not OTA. It is a shame that Huawei did not release the update worldwide. My 32 WiFi version got an OTA on Nougat once already (to B303).

Now I see that your Mediapad is with EU or at least non-US code (that is what C100 means), just like mine. This may be the reason why yours is not getting the OTA to Nougat. You should get the custom version for US, I do not know which one it is. I have heard of people buying the M3 from an unofficial seller that gets them, even here in Romania. Be very careful with the C code. I bet that if you are able to roll back to a US version of MarshMallow, you will also receive OTA to Nougat.
[Huawei Mediapad M3 Questions & Answers] AndroidVeGe:
You have European (C100) for which B303 is the current latest firmware with Android 7.0, Emui 5.0.1 and security patches as of November 2017. B350 is not meant for your device and as you noticed it doesn't work. Bigger number isn't better in this case, it's just meant for other devices. I have also updated from B006.

hi all

i have quest about upgrade to emui5.0

my device version is btv-w09c128b005, i have unlocked and rooted successfully. today i get a system upgrade, the version can upgrade to btv-w09c128b005d001_b352d002.

if i want to upgrade, how step should i do ?

thx
[Huawei Mediapad M3 Questions & Answers] tmihai20:
[MENTION=8772823]Infinitlee[/MENTION]: you should unroot it, you will most likely not be able to install the official OTA with root and modifications done to the system partition.
[Huawei Mediapad M3 Questions & Answers] Infinitlee:
[MENTION=473928]tmihai[/MENTION], thx for reply.

so how to unroot ?? if i recovery system to unroot and i need unlock device again ?

do you have any guide ?
[Huawei Mediapad M3 Questions & Answers] tmihai20:
[MENTION=8772823]Infinitlee[/MENTION]: sadly I do not have a guide. Go back to the topic where you found the root instructions, maybe there are unroot instructions. I also have the C100 variant, we are not even in the same region here.
[Huawei Mediapad M3 Questions & Answers] Infinitlee:
thx.

if i recovered to unroot successfully and upgraded to the emui5.0,

but i want to root device at emui5.0, i need to unlock then root again ?
[Huawei Mediapad M3 Questions & Answers] tmihai20:
[MENTION=8772823]Infinitlee[/MENTION]: once the bootloader is unlocked, you cannot lock it and unlock it, it does not make sense. You need to look up here on XDA if anybody managed to root their Mediapad M3 running Nougat, but with your exact version (btv-w09c128b005d001_b352d002). I think there is a rooted kernel image for mine (C100B303), but I do not want to root mine, I do not feel the need yet.
[Huawei Mediapad M3 Questions & Answers] tim_h:
Hi everyone,

there is another thread regarding the latest update to B307 (which mostly lifts the security patch level to November 2017): https://xdaforums.com/mediapad-m3/how-to/update-b307-t3654744/

Unfortunately, I have problems installing the update. I repeat here what I wrote there, maybe someone has an idea or run in the same issue?

I have a BTV-DL09C100 running on B303. It is fully stock, so unrooted and with stock recovery. I originally updated it to B303 via FirmwareFinder through B302. So far, everything worked fine.

Now I tried to update to B307. As the update is not yet available via the system update utility, I tried installing both the OTA and the full ROM through the FirmwareFinder proxy method. They both download and validate ok, but then there is a failure during installation.

Any idea why that is? The only thing I can think of is because I might have a "non-official" B303 installed that I got through FirmwareFinder before the official release? I tried installing the last B303 listed in FirmwareFinder to try to get to the official version, but that also produces an installation error.

What can I do now? Wait for the official B307 update and hope that it works?

What if that produces an installation error as well?

Any advice would be very much appreciated, thanks in advance!
[Huawei Mediapad M3 Questions & Answers] 30adi:
I've got B307 installed via OTA, came from B303.

Didn't you get any OTA?
[Huawei Mediapad M3 Questions & Answers] tim_h:
Not yet. Someone wrote in the other thread that rollout started on 18th December 2017 and takes 8 weeks to complete. So could be that I will still get it. I hope I will and that it will install fine. Otherwise I might have to use Huawei's rollback to the Marshmallow version DL09C300B009 and hope to get proper OTAs from there.
[Huawei Mediapad M3 Questions & Answers] nospherato:
Same problem here... Also BTV-DL09C100 running on B303 and can not install any newer firmware via firmware finder and not getting any OTA.

[MENTION=3838420]tim_h[/MENTION] did you try to rollback, yet? If "yes", did you get any OTA for B303+?
[Huawei Mediapad M3 Questions & Answers] tim_h:
No, haven't tried yet (no time to mess with my tab right now). I guess I will wait two more weeks until the "rollout period" is over. If I don't get any update until then, I will probably try the rollback. If you (or anybody else) try it, please report whether it worked!
[Huawei Mediapad M3 Questions & Answers] nospherato:
[MENTION=3838420]tim_h[/MENTION]

Well I tried rollback using the firmware you can download via huawei hp...

I would not really recommend doing this because of:

https://xdaforums.com/mediapad-m3/help/bricked-m3-recovery-save-t3745349

My tablet is on its way to the only support center in germany. Nice fact: The guys I phoned with told me they never had this kind of problem until now :D
[Huawei Mediapad M3 Questions & Answers] tim_h:
Wow, that sounds really bad. Did you use the BTV-DL09_C900B300 rollback package from the Huawei download page? Are you sure you used the correct one (DL09, not W09)?

Not sure I want to risk this. But I do want to get the B307 update, in particular for the security patches. :mad:
[Huawei Mediapad M3 Questions & Answers] nospherato:
Hi, yes I tried the right package for DL09.

(Just checked the sdcard as the package is still there)

I hope the service center will fix the software problem, otherwise I'll unlock the bootloader and have to flash via fastboot :-/

(Still have 8 month guarantee, so this is only my last hope.)

It's still possible it was just bad luck, but I would not really try it again...
[Huawei Mediapad M3 Questions & Answers] tim_h:
Thanks for the info. I am not sure where that leaves me - should I try the rollback or not? So the service center offered to fix it free of charge? Or was there any discussion? Would be nice if you could keep me posted on what they do (if you don't want to post it here, maybe by PM).

This is actually my only Android device that I wanted to leave full stock so that I get the regular OTAs. But it seems with Huawei OTAs don't really work out that great even on stock.

So say I am willing to unlock. Would there be a way to flash the B307 update in spite of it failing on the stock recovery install? Maybe via TWRP? Any advice would be greatly appreciated.
[Huawei Mediapad M3 Questions & Answers] nospherato:
If you unlock your bootloader before trying to flash the huawei packages you should not really have as many problems as I do, because fastboot is always working and you can use this

to reflash recovery, boot etc.
[Huawei Mediapad M3 Questions & Answers] tim_h:
Hmmm, but won't there be problems with the rollback if the bootloader is unlocked? In the instructions for the rollback package it says that the bootloader has to be locked.
[Huawei Mediapad M3 Questions & Answers] nospherato:
Still at least you should(!) be able to install twrp and an uploaded version at least to save your pad.

(For example someone can upload an complete update for you, at least this way it worked with other android devices before.)

Mine arrived today at the service center but until now no news if they can repair it or not.
