It is WORKING!

I downloaded the latest Chinese version using the tool [MENTION=3732677]Slavon-93[/MENTION] linked, version BTV-W09C233B022 from December 16 2016. I flashed it and after restarting the tablet, I have a Chinese version tablet, with 5Ghz band wi-fi working.

I lost custom recovery and root and may reflash them later.

I got some apps back that I previously removed, but happily all my other apps were still installed and configured.

Thanks [MENTION=3732677]Slavon-93[/MENTION] :D

p.s. I re-flashed TWRP and SU and now have custom recovery and root back
[Huawei Mediapad M3 Questions & Answers] jmjm003:
Can you select english as the language?
[Huawei Mediapad M3 Questions & Answers] E.Vogel:
Yes you can, and since English was my selected language before I flashed the Chinese ROM it stayed as the selected language, so I never got a Chinese welcome screen and had to find out how to change it to English.
[Huawei Mediapad M3 Questions & Answers] Dekan54:
So this is a solution to get the "5Ghz band" working on a US WiFi only?
[Huawei Mediapad M3 Questions & Answers] Slavon-93:
Those, who have a US tablet, could you please upload your entire /cust folder somewhere? If Chinese firmware is a solution, maybe there is something in /cust, that blocks 5GHz wifi? I wanna compare it to Chinese and Russian versions and maybe find something interesting.
[Huawei Mediapad M3 Questions & Answers] jmjm003:
[MENTION=5632748]E.Vogel[/MENTION] forgive me for being new to Huawei way of doing things. You said you flashed the Chinese ROM. Flashing makes me think of my Nexus 7 where I actually flashed the *.IMG files.

I downloaded the file you mentioned and I have update.app after extraction. I recall reading somewhere about creating a folder and transferring said file to device and restarting it. I'm curious if this is the route you took? I personally prefer fastboot flash but will have to do with what works. Thank you.
[Huawei Mediapad M3 Questions & Answers] Slavon-93:
Forgive me for not being [MENTION=5632748]E.Vogel[/MENTION], but let me explain. Huawei devices are not usual in terms of partition structure. For example, they have 2 recoveries, designed for different things. For a Nexus owner their update structure is also strange. Once upon a time, you could create a "dload" folder in /sdcard or in external SD, choose local update in update utility on your device, select update.app or update.zip, reboot and watch the device updating. Now we don't have an option to choose a local update, so the quickest way to install FULL OTA is from TWRP. You just need to put update.zip (~1.8 Gb) somewhere in /sdcard or other place, reboot into TWRP, press the Install button and select this file. TWRP installs it and you get your Chinese firmware. I recommend to make a backup first, in case something goes wrong. After installing FULL OTA you still get your apps and settings in place, but after a factory reset, you will lose Google Play and other a Google apps, and will have to manually install them from HiApp. Also, you will have to reinstall TWRP, root, xposed and other things you probably have flashed before.
[Huawei Mediapad M3 Questions & Answers] jmjm003:
I appreciate the reply all the same [MENTION=3732677]Slavon-93[/MENTION]. So creating the dload folder and dropping update.app in it no longer works?

I've not modified anything on my device other than fixing DPI so apps are in tablet mode.

Any idea what each recovery does since it has two of them?

I like to know there's a way out of a screwup if it happens. Nexus 7 was simple to fix.

Thank you.
[Huawei Mediapad M3 Questions & Answers] Slavon-93:
Huawei devices have two recovery partitions: recovery and recovery2.

Recovery has generally all the same features a typical Nexus recovery has, except it doesn't have an option to apply update.zip and has a touch interface unlike the Nexus recovery.

Recovery2, called eRecovery, also has a touch interface and is designed to make a totally screwed up device great work again. It has a button to download full firmware and install it but on my device it said "No firmware found" after connecting to Huawei servers. People in Russian forum say it works only if you're in China and have a Chinese device. Anyway, if eRecovery does nothing, I considered it totally useless and replaced with TWRP: fastboot flash recovery2 twrp.img

Generally Huawei devices can be restored the same way a Nexus device can. TWRP and fastboot work the same. Personally I prefer to make a total backup of all partitions in device with "dd". I think it will give me more flexibility in restoring if something goes completely wrong. On DL09 model, only modem partitions are the problem. You can find fastboot versions of Chinese ROMS easily, but after installing them, I've lost everything related to phone functions. The only way to fix it was installing Full Chinese firmware in form of update.zip with TWRP.

And about dload folder. I have no idea how it works. I am also a former owner of Nexus 7 and the logic of Huawei is new to me, so I don't know some nuances. On earlier devices there was another option to update: you put update.app to dload folder, dial *#*#2846579#*#*, select Software upgrade -> SDCard Upgrade, the device reboots and installs the update. Again, on my device this trick didn't work and update installation stopped at 5%, saying it's incompatible with my device.
[Huawei Mediapad M3 Questions & Answers] E.Vogel:
[MENTION=5035713]jmjm003[/MENTION], I also come from a nexus 7 and Huawei devices are different.

First of all there is no formal web site with all factory images and/or OTA to download, I had to use a tool an XDA user developed to find the factory image I needed.

The second change is that the factory image (file update.zip) does not contain *.img files inside like in Google images and contains "update.app" 1.8GB file and some other small files.

To flash the ROM I tried to use ADB sideload but got an error message about the file being unreadable, so I copied the file to the tablet and flashed it using TWRP install function like any other zip file.

[MENTION=3732677]Slavon-93[/MENTION], my /cust/hw folder changed from before and now contains only two sub-folders "cn" and "default"

I uploaded the entire /cust folder to Google drive, use this link to download it.
[Huawei Mediapad M3 Questions & Answers] Slavon-93:
Thank you but I know what's inside Chinese /cust folder as I am using Chinese firmware myself. I am interested in untouched /cust of US version of tablet because I think there can be some option in local.prop or somewhere else, that blocks 5GHz Wi-Fi. I can try to look for it by comparing Russian, Chinese and US cust folders.
[Huawei Mediapad M3 Questions & Answers] E.Vogel:
I uploaded my original U.S. version /cust folder. I took it from the nandroid backup I did before flashing the Chinese ROM.

use 7zip to open the file

Whoa. I forgot I started this thread and here we are with confirmation of hardware and a fix. Good work and Happy Holidays! :good:
[Huawei Mediapad M3 Questions & Answers] jmjm003:
Found it on the US tablet!

Using Root Explorer I went to /cust_spec/system/etc/cfg_btv_wifi_only_hisi.ini

band_5g_enable=0 change it to band_5g_enable=1

Then restarted and I could see and connect to my 5Ghz network.

So far it seems to work fine but we are talking minutes since I got it changed.

[Huawei Mediapad M3 Questions & Answers] jmjm003:
While I continue to poke around it appears that 5Ghz can be enabled from a few locations. I'm guessing but I'm finding the same file.

Same file I mentioned above is here too. Also has the backup that was created.

/cust/special_cust/BTV-W09/hw/usa/system/etc/cfg_btv_wifi_only_hisi.ini

I purchased a huawei mediapad m3 from amazon (in the US), and in Huawei eRecovery mode, I have noticed that my 5GHz band connection showed up and was able to connect to it. No idea what that means outside of it has the physical capability, but hope this info will help
[Huawei Mediapad M3 Questions & Answers] johje:
Just a quick note - after running the stock Huawei recovery, the 5Ghz band was still enabled on my US version of the M3.

Wish I read this thread to the end instead of installing the Chinese version.

The Chinese version didn't have the Play Store and while I managed to install it via the gapps project, it still has issues. Is there a way to get the US version back?

Does anyone have a clean backup (One without your personal info, files, etc) I could use?

Thanks.

[Huawei Mediapad M3 Questions & Answers] gaidin43:
Did you root first to enable this? or did you just connect with the recovery and it was still enabled after you restored?
[Huawei Mediapad M3 Questions & Answers] johje:
I rooted first to enable the 5Ghz band, and it was still enabled after I had run the stock recovery.
[Huawei Mediapad M3 Questions & Answers] gaidin43:
Is there anyway to root without losing the stock recovery?
[Huawei Mediapad M3 Questions & Answers] johje:
I believe you can install TWRP in the eRecovery partition (which seems to be useless in the US) and keep the stock recovery partition.
[Huawei Mediapad M3 Questions & Answers] nicolap8:
Very good! At end someone arrived at it!

Remember that we have 2 volume keys so 4 combinations...
[Huawei Mediapad M3 Questions & Answers] johje:
I was able to install the US Nougat Beta and can confirm that the Full OTA version can be installed on a rooted and unlocked US -Version through the Firmware Finder DNS method. I was able to change the tablet from using the phone app versions of apps like chrome and YouTube by running the adb density command and setting it to 320 as anything higher and the settings app doesn't work. After that, I was able to install TWRP into the recovery2 partition (eRecovery partition) which left the standard recovery partition untouched. I like installing to this partition because TWRP can be launched by holding volume up in the "Device Can't Be Trusted" screen. What I haven't been able to find, is a version of Supersu that works with this version of Nougat. Every version of Supersu I have tried fails at patching the boot image. So without that I cannot get the 5Ghz wireless radio or Xposed framework working.
[Huawei Mediapad M3 Questions & Answers] gaidin43:
You can change the screen density under developer options on 7.0. It does not last last reboot, but is easy to do. Just set it to 650 or 700 to get tablet resolution
[Huawei Mediapad M3 Questions & Answers] johje:
If you haven't changed view mode (at least it was that way in Marshmallow on the M3) if you run "adb shell wm density 320 && adb reboot" the density change is persistent and will stick after reboot. I can confirm that my density change has stuck after rebooting multiple times.
[Huawei Mediapad M3 Questions & Answers] johje:
I was able to root the US version of the tablet with Nougat with Magisk, but how the 5G is enabled/disabled has changed and I cannot find the file or spot in the old file to update to allow 5G so I am stuck using 2.4ghz.
[Huawei Mediapad M3 Questions & Answers] johje:
So it seems all I needed was a better file manager. I was using Total Commander, which it turns out is not as good as Root Explorer. The file to turn on 5Ghz wifi is called "cfg_btv_hisi.ini" and is in the "cust_spec\vendor\etc" directory, which didn't even look like a folder in Total Commander, and is the same, just change "band_5g_enable=0" to "band_5g_enable=1" save enabling the permission change to write and then reboot. All the settings I had for 5Ghz SSIDs in Marshmallow were still there, I didn't even have to type in passwords again.

Now all I need to do is find a new way to do all the things I did with xposed framework, which doesn't work with Nougat yet.
[Huawei Mediapad M3 Questions & Answers] longbungbu:
Hi, My M3 came from Japan, I flashed it with EU firmware. Make everything changed like all of above comments. from "band_5g_enable=0" to "band_5g_enable=1" to "Open /system/build.prop and find ro.config.hw_is_hide_wifi_5g=true and change it to "false" . So now what I got just only 5G band enabled, I knew it because in mobile hotspot config allow to select 5G band. But I can't see any 5G wifi network around.

One thing I just wondering is the build.prop file, when I changed permission it to write and leave it after modified to false value. I restarted the tablet and it stuck in boot loop. I have to go in TWRP to modified the build.prop back to 0644 and it boot as normal.

Please give me some help... Many thanks

Hello everyone,

I'm a semi-noob hoping to find some clarification here. I just bought a US version BTV-W09 that has EMUI 5.0. I want to enable 5GHz WiFi but all the info I have been able to find is about rooting the old EMUI 4.x system. How can I root with the update and/or enable 5Ghz WiFi? Sorry if the answer is out there somewhere, I searched and was not able to find anything. Thanks in advance!

International model supports 5Ghz

As posted elsewhere, the International model BTV-DL9 supports 5Ghz and automatically upgraded to EMUI 5.0 & Android 7.0

I was lucky enough to be able to return the US version and buy the BTV-DL9 from a Taiwan EBay seller, plugplayers. The price included priority shipping & 5 days later it arrived!

While it costs more, it was well worth it to me.

While I am able to get WiFi speeds over 200Mbps (I pay my provider for) activating the Bluetooth severely slows it down (@20mbps) which I can live with since I very rarely use both at the same time.

One trick to setting up this model is to use the "airplane mode" while doing so.

This model deserves an easy 5 star rating.

Huawei C. S. was a waste of time.
[Huawei Mediapad M3 Questions & Answers] Redline143:
Total Noob Stuck at 20Mbps DL on 50Mbps connection?!?

Short of it: iPhone 7 and computer have no issues getting the 50/12 I pay for. My $300 U.S. Version (Amazon) Mediapad M3 8.4 gets only 20Mbps D/L; verified only connecting to the 2.4Ghz band of my 2.4/5.0 Wifi Router by logging into it. EXTREMELY dissatisfied that this price of a Pad is getting such slow speeds - less than half of my other devices. Ridiculous!

I want to re-enable the 5.0Ghz band, but I can't figure out how, for the life of me. I've been pouring through this forum for hours regarding my BTV-W09 U.S. model.

Haaaaaalllllpppp plz!!!
[Huawei Mediapad M3 Questions & Answers] knotle:
I also have the U S version of the M3. I am getting full max speeds on my 75/5 connection. I let it update to emui 5 and nougat 7.0 right out of the box. Is yours still running 6.0?
[Huawei Mediapad M3 Questions & Answers] Redline143:
Yep, 5.0 and Marshmallow 6.0.

Where'd you get yours? Amazon here... BTV-W09, build # BTV-W09C128B005.

Talked to Huawei today and they said it's not a matter of if, but when the 5.0/7.0 release will be available to me. It just comes out at different times for different build #s. They said it'll fix my D/L slowness, too... Fingers crossed that it does, and soon!
[Huawei Mediapad M3 Questions & Answers] knotle:
I purchased mine from Newegg in July. Mine is the BTV-W09C128B351. As soon as I went online it offered the update to nougat.
[Huawei Mediapad M3 Questions & Answers] Redline143:
Ah, so mine's the XXX-XXXXXXXB005 and yours is the XXX-XXXXXB351. 'Preciate it.

It would stand to reason that yours is newer if the build numbers progress sequentially. Should be just a matter of time before mine updates too, according to Huawei (like I mentioned), and they said it'll fix my speed. Unfortunately they can't give me an exact date because it's in Google's hands - they're the one's who integrate Huawei's-supplied 5.0 into their Nougat 7.0 and push the firmware update out.

Man, it'd be so much better if I just had a date! LOL. Even if it were a month or two, actually KNOWING the date would be great!

So you've logged into your router and actually verified that your tablet is connected to both the 2.4 AND 5.0 bands, now that you're on the 5.0/7.0 combo update?

Hi, can you enlighten me how to get the unlock password from EMUI website?

I have tried quite a few times, but it prompted me with an error. Thanks a lot!
[Huawei Mediapad M3 Questions & Answers] Redline143:
So, that was it--just the OTA update to get those speeds, or did you have to root/enable 5Ghz?

If not, does the 5.0/7.0 version have 5Ghz enabled? Or do you only get 2.4Ghz but still get your full service speed of 75/5? Thanks!
[Huawei Mediapad M3 Questions & Answers] knotle:
I am getting my full speed on the 2.4Ghz. I have not rooted it to enable the 5Ghz. I had thought about rooting but decided to use DNS 66. It does a good job on ad blocking.
[Huawei Mediapad M3 Questions & Answers] Redline143:
Ah, gotcha. Well, returning my Amazon (older build #/no update available yet) pad and ordered one from Newegg today that has the OTA update ready out-of-the-box.
[Huawei Mediapad M3 Questions & Answers] barotropic:
Please let us know if the tablet you get from Newegg updates immediately to nougat!

I ordered mine from Amazon nearly a month ago and no OTA for nougat.

Can't understand why there would be a difference. Same model - USA wifi-only, 32gb?
[Huawei Mediapad M3 Questions & Answers] AnarchoXen:
I guess I'm getting ready to return this thing. Bought from Amazon the other day and with seemingly no support what is the point. It will be interesting to see if the New Egg version is updated.

It is a price thing? Cheaper on Amazon than NewEgg...

Edit...I'm good now. For anyone that cares. Firmware finder updates..
[Huawei Mediapad M3 Questions & Answers] Redline143:
Will do. It's set to arrive Wednesday.

---------- Post added at 06:19 PM ---------- Previous post was at 06:16 PM ----------

I got it for the same for-sale price on Amazon: $219.99. On both sites it's normally listed at $299.99, but I was lucky when I checked on NewEgg because they just happened to be running a sale that was the exact same price I paid for it on Amazon when they were also running a sale. I'm the kind-of guy who'd have waited patiently for another sale instead of paying an extra $80 just to have it sooner. To me that's the same as throwing money out the window. Besides, we all know how the prices of technology decline over time. In other words, if it's showing $299.99 right now on either or both sites, it's just a matter of time until the prices drops.
[Huawei Mediapad M3 Questions & Answers] wase4711:
what kind of support do you need/expect on an entry level tablet?

I updated to 7.0 via Firmware Finder, super easy..
[Huawei Mediapad M3 Questions & Answers] AnarchoXen:
Based on what I've read I wasn't sure I wanted to go the Firmware Finder route.

You have no issues like a bad BT connection or any of the other problems some have reported?
[Huawei Mediapad M3 Questions & Answers] wase4711:
nope, first I upgraded to b350, then, a short time later, the tablet automatically updated to b351

No issues that I can tell; I just bought this about 10 days ago myself from Amazon..
[Huawei Mediapad M3 Questions & Answers] Redline143:
They (NewEgg) sent me the old build number too!!! o.O (last 3 digits 005 instead of 351). I was livid! They're trying to reconcile it now, especially because their add for the pad SAYS OTA update for EMUI 5.0 and Nougat 7.0. One of the gentlemen a few posts up got his 351 build from NewEgg and it immediately updated.
[Huawei Mediapad M3 Questions & Answers] AnarchoXen:
Thanks for the vote of confidence. I did the firmware finder last night at all is well. The tab auto updated to 351 right after, as you said.

Well, it looks like there's finally a definitive light at the end of the tunnel for us XXX-XXXXXX005 build number folks. Check out the correspondence I received straight from the NewEgg supervisor with whom I've been working on getting a remedy for weeks:

"Thanks so much for getting back to me! I actually just received an update at 11:24 AM (PST). My team was working on reaching out to Huawei and they responded by letting us know: Huawei has confirmed that an over-the-air update to Android Nougat will be available for this model on January 8th. This information was provided directly from a Huawei representative, I hope this helps. And please let me know if you have any additional questions or concerns. "
