Ok, I did the update and got root installed again. I'm trying to get the 5ghz band working again. I think the last time I did it, I changed this file: /cust_spec/system/etc/cfg_btv_wifi_only_hisi.ini

On the updated version, I can't find a /cust_spec/system folder and I can't find that ini file. If you got it to work, which file did you change?
[Huawei Mediapad M3 Questions & Answers] jionny:
same file just hidden better cant remember which one but it was like four folders just click on each one until you find it
[Huawei Mediapad M3 Questions & Answers] Redline143:
Finally got the update on the 9th (1 day late). No performance boost in D/L speed. I'm not going to root because 25Mbps is perfectly fine for my use, but my hope is that one day they get the FCC approval to turn on the 5GHz band on the U.S. models and push the change in a future update so I can get my full 50Mbps D/L speed.
[Huawei Mediapad M3 Questions & Answers] woody1:
Do you think the file is under /cust_spec or is it in another directory?
[Huawei Mediapad M3 Questions & Answers] jionny:
for sure cust/spec
[Huawei Mediapad M3 Questions & Answers] woody1:
I've looked under cust_spec and everywhere else I can think of, but I can't find the file. Are you sure they didn't change the name of the file?
[Huawei Mediapad M3 Questions & Answers] jionny:
No name change if I remember right besides hiding it there are 2 folders with that

sorry but I know it is there for a fact because after I upgraded and rooted I got back to it, not as easy ass the first time but I eventually found it I used solid explorer. Also be careful I have seen people say you have to flash that to get the settings, that is absolutely untrue it is in the root of your phone enable the same way you did before change =0 to=1
[Huawei Mediapad M3 Questions & Answers] woody1:
Ok, I found it. For anybody else who's looking, here's what seems to work:

File location: /cust_spec/(version)/special_cust/BTV-W09/ hw/usa/vendor/etc/cfg_btv_hisi.ini

Search within the file for the section after#wifi call params

Change 'band_5g_enable=0 ' to 'band_5g_enable=1'

Reboot and it should stick.

I used Solid Explorer and the SE Explorer file editor. Of course, you have to be rooted to do this.

I think the file in the previous version had a different name, but I'm not sure. It might have been: /cust_spec/system/etc/cfg_btv_wifi_only_hisi.ini

With the BTV-W09128B352 update. Root went well. TWRP class just fine. SU role device just fine. Device runs great. A little smoother than before. A few aesthetic changes with settings & status bar icons. The main thing the update did was patch the 5Ghz exploit. No longer able to be done in the path that was previously discover for the US model. Going that someone figures out another one fast. I hate being on dual-up again.

Thanks! The path was different on mine. But your direction led me to it. Much appreciation. /cust_spec/vendor/etc select cfg_btv_hisi.ini. A little more then half of the way down, change "band_5g_enable" 0 to 1.
[Huawei Mediapad M3 Questions & Answers] wase4711:
so, you have to be rooted to enable the 5ghz wifi, correct?
[Huawei Mediapad M3 Questions & Answers] AnarchoXen:
Yes.
[Huawei Mediapad M3 Questions & Answers] wase4711:
that sux; I bought one for my wife a month ago, and returned it for that reason; she wants me to buy it again, and I thought I read that they fixed that major mistake, but, it looks like they havent..

Oh well, guess I will just over pay and buy her a samsung, since they dont cripple the wifi on their tablets like this
[Huawei Mediapad M3 Questions & Answers] woody1:
Just my opinion, but I switched from a Galaxy Tab S (which I think is the best Samsung Tab) to the Mediapad. I switched mostly because my battery was old and I couldn't find a new one that was any good. It took a while to adjust to the Mediapad, but now I like it much better than the Tab S. The downside for the Mediapad is that the community of users is small and support is spotty. In order to get it working optimally, you will have to dive in and unlock the bootloader, root, etc. I always do this with my Android devices anyway, but I understand that not everybody wants to invest the time and work to get all that together.

Unfortunately, Android tablets are very much a niche market and most of them suck. If you want to get the most out of them, you kind of have to be your own support person.
[Huawei Mediapad M3 Questions & Answers] wase4711:
agreed; I have been rooting android stuff for many years, but, since this tablet is for my wife, and she uses her stuff for corporate work sometimes, and rooting can cause issues, I rarely root any of her stuff..

It sucks that Huawei has ruined this tablet by making it so difficult to turn on something as basic as 5ghz wifi, especially when the firmware has it built in..this is why they will NEVER be a "major" player in the US market..stupid stuff like this just alienates tons of potential buyers..
[Huawei Mediapad M3 Questions & Answers] woody1:
I agree that not activating 5Ghz wifi is pretty Mickey Mouse. My guess is that they didn't want to go through the FCC licensing process to activate 5Ghz in the US. As far as using the tab for your wife, I suppose you could root it, fix the wifi, then unroot it to meet her corporate requirements. I think you can relock the bootloader without wiping the device, but I don't remember for sure. You will definitely wipe the device when you unlock the bootloader.
[Huawei Mediapad M3 Questions & Answers] wase4711:
yes, its easy to do all that, but I try not to support phucked up companies like Huawei, who do stupid stuff like this and dont work for the customers, but just for their corporate interests..If you dont vote with your checkbook, you dont have any other way to express your dislike for lousy corporations..

Hi All -

Long time lurker. You guys have helped me figure out things many times but never posted anything. Finally sick of fighting with old junk tablets and just purchased BTV-W09.

First thing I found was a post on Amazon that you didn't have to root to get 5G but, don't quite see what poster was hinting (Step 3?).

Anyway, Why do you have to root? It seems to me that a script could make modification?

This is where the Amazon poster pointed:

<ministryofsolutions tutorial>

Last thing I want to do is brick a tablet I received yesterday, 128 memory card coming today and the thought of getting 5G has captured my attention.

Thanks :)
[Huawei Mediapad M3 Questions & Answers] GarlicBreadFox:
Without root you're basically on iOS mode with extra access to "media" folders and such. You don't have access (read or write) to system folders, like the one required here.

I checked that site, seems to be nothing but how to root tutorials and whatnot. Nothing about magic 5 Ghz without root.

But since the guy's tutorial is cleaner than the mess on this forum regarding unlocking bootloader I will give it a go today (what I mean is at least the guy's link to Huawei's request code site is the right one, the one on XDA redirects to a 404).
[Huawei Mediapad M3 Questions & Answers] Windows_Washer:
On Amazon he wrote:

TIPS

- 5 GHz WiFi can be enabled by rooting the tablet (which I didn't want to do). Instructions can be found on xda-developers forums (Google it)

- You can upgrade to Android Nougat 7.0 quite easily by following the instructions found on MinistryOfSolutions (I'm unable to paste the link here -- Amazon restriction). Google for the search term: "ministryofsolutions huawei btv-w09 mediapad m3 nougat".

Only "Installation Method 3" (which does not require Root) worked for me.

Note: for your reference, the USA model I received is "BTV-W09".

- 5 GHz WiFi was enabled during Step 1 of 2 (Firmware Upgrade) of when I upgraded to Android 7.0 Nougat, confirming with 100% certainty that the tablet is capable of it. After finishing Step 2 of 2 (Data Upgrade), however, it lost support for it. Again, probably of FCC licensing restrictions. So you know, the tablet worked perfectly fine after the 1st step (Firmware upgrade) (which also enabled 5 GHz WiFi). However, I went ahead with the 2nd step to ensure I got EVERYTHING upgraded.

Update: I think I confused the upgrade with the wifi - It helps to be awake...
[Huawei Mediapad M3 Questions & Answers] elcidroyale:
God I almost gave up on this tablet. Bricked two of them just because I wanted 5ghz but in the end didn't want to root.

In any case, the easiest way to get 5ghz and stay on stock was to install an EU firmware as EU has 5ghz available to them. I found some downgrade to MM method online that had EU firmware files.

Now stuck on MM trying to get to Nougat.
[Huawei Mediapad M3 Questions & Answers] sam10000:
Hi

Any luck with getting back 5 GHz with a European ROM, without rooting?

Is there a EU ROM zip available for download and which the US BTV-W09 can flash with?

Please let us know.

Thanks.

---------- Post added at 06:23 AM ---------- Previous post was at 05:52 AM ----------

Did you put the unzipped European Nougat firmware (a dload folder) in a micro SD card and flash it?

Thanks for your post, woody.

Well, I certainly hope someone can help me out because I am exhausted from working on this device. I guess the good news is that I am almost to the finish line on this but I have fallen flat on my face a step away from the finish line, haha, and I am sure it is something so simple and dumb that I am missing.

So I am all rooted and have a US-wifi only version (purchased from Amazon) and am running B353, but when I try to save my edit of this file to change 'band_5g_enable=0 ' to 'band_5g_enable=1', I am not able to and I have tried Total Commander Editor, ES File Explorer, and fx TextEdit (and installed the root add on for fx File Explorer). Also, I have granted super user permissions to the apps. Total Commander gives the most info about the error so when I go to save, it says...

"Re-mount drive?

Re-mount as read/write: /version/

Command: mount -o rw,remount /version"

So I hit "OK" (I have done this many times so tried "cancel" at this point even though I am sure it is not correct), then I get "Re-mount succeeded" banner at the bottom but at the same time, I get an error message...

"Change permissions

Error writing to file: /version/special_cust/BTV-W09/hw/usa/vendor/etc/cfg_btv_hisi.ini

Change permissions?"

So I hit "YES" (but have done this many times so even tried "NO" even though I am sure it is not correct), then I get something like the above error in a splash banner at the bottom of the screen...

"Error writing to file: /version/special_cust/BTV-W09/hw/usa/vendor/etc/cfg_btv_hisi.ini" (approximately)

I have rebooted many times and like I said, tried many times and different options when I get errors and I have never been able to save the 1 for band_5g_enable and obviously don't have 5GHz working.

Any ideas on this? Is it maybe a setting in an app somewhere or a step I missed or something? I am so frustrated with this and it is just simply changing and saving one number in one file (it seemed deceptively so easy and in fact, it should be...smh).

Any help will be greatly appreciated. Thanks!

Is it possible that OEMinfo on your M3 still indicates US, and therefore European OTA updates are unavailable?
[Huawei Mediapad M3 Questions & Answers] Franko30:
A little OT, but still: im in Germany and almost all of my Huawei devices so far (except the M3 up to now) didn't get the OTA updates they were supposed to get. I then had to get the the OTA updates as downloads from somewhere... That's why I'm glad FirmwareFinder exists...
[Huawei Mediapad M3 Questions & Answers] elcidroyale:
I'm on EU version B006. No OTA update to Nougat. Not one single update on FF works for my EU version. There is supposed to be a specific path from B006 to Nougat BUT the next Firmware update I need is not on FF or anywhere to be found. So I'm stuck.

I pretty much hate this tablet now. I had to go through all this nonsense just for 5ghz. And now I find if I use Bluetooth whith wifi, my wifi speeds crawl. Huawei customer service is horrible as well.

Well, you sort of went rogue by switching to the EU version. Why not go back to the US version, then update and root to get 5mhz? That's what most of us have done.
[Huawei Mediapad M3 Questions & Answers] elcidroyale:
Hah you have a point! I didn't want to root so I could continue getting OTA updates. I just remember back when it was rooted, it was impossible to unroot. I tried so many many ways and eventually it bricked and I had it replaced. Hmm maybe I just stick with stock US and 2.4ghz

[Huawei Mediapad M3 Questions & Answers] sam10000:
Is it possible that, after the rollback using EU files, your tablet's oeminfo stays as US, and as a result cannot do OTA upgrade to Nougat.

The assumption is that the "Build number" is not the same as oeminfo. "Build number" showing C100 (after using the rollback procedures and EU files) does not mean that oeminfo was changed during the rollback.

oeminfo

https://xdaforums.com/mediapad-m3/help/oeminfo-collection-t3518535

To receive OTA upgrades, is it therefore necessary to:

1 Root (including replacing stock recovery with TWRP)

2 Replace original US oeminfo with EU oeminfo, and

3 Unroot and replace TWRP with stock recovery?

This is effectively rebranding (to an EU BTV-W09), isn't it?

Thanks in advance for any suggestions.

Hi, so I was able to root my Huawei and get it to 5ghz wifi but I need to unroot it to access certain apps. The only problem is that after I unroot it 5ghz wifi gets locked again. Is there any way around this?
[Huawei Mediapad M3 Questions & Answers] tek3195:
I would imagine most have this figured out by now. But I have the U.S. variant and used Hisuite to upgrade choosing the Developer version. It still shows as US version and 5 Ghz wifi was no enabled. Then installed TWRP and Magisk. Found files at /vendor/etc/cfg_austin_hisi.ini , ...../cfg_btv_hisi.ini and ..../cfg_btv_wifi_only_hisi.ini. All three contained "band_5g_enable=0" edited 0 to 1 and rebooted tablet with 5ghz wifi working fine. I connected to hisuite again and there was another update which did not install. I then took the update which I had captured from tablet and flashed it with TWRP

wiped data before flashing update. Makes me wonder if possible for those not wanting to root if it could be done with Magisk and a root file manager. Upon uninstall Magisk will restore stock boot.img. No TWRP or perm root just unlocked bootloader which I haven't had cause issue with update before in other Huawei devices. At worst it re-locked bootloader after update.

I found Magisk had to have correct boot.img per update version increment or patched.img would not boot.
[Huawei Mediapad M3 Questions & Answers] PlaidRadish:
CONFIRMED - (BTV-W09 working 5G USA variant Nougat)

I finally have my BTV-W09 working exactly how I want it:

TWRP

Magisk 20.3

EMUI disabled

Nova Launcher working as default

Bluetooth working (formerly disabled with NRD90M test keys ROM)

... and now, 5G WiFi working, also!

...So, I wanted to just take a second to confirm that the location provided by [MENTION=1174036]johje[/MENTION] for USA BTV-W09 (I'm currently on W09C128B356) is exactly where I found the 5G enabler tag.

However, that location listed above is actually a shortcut.

The ACTUAL LOCATION for a BTV-W09,

running stock EMUI, 5.0.3 (Android 7.0), is here:

"/version/special_cust/BTV-W09/hw/usa/vendor/etc/cfg_btv_hisi.ini"​

As mentioned above, change the "band_5g_enable=0" to "band_5g_enable=1" with a text editor, and reboot.

*Remember* you HAVE to have root for this to work. See other write-ups in XDA-Developers website for how-to's.

So, I found the OTA update packages for the FRD-L14 to B320 (and B317)

I really wanted to update... but I'm not sure how.

I'm rooted, with TWRP and SuperSU installed, and it all works ok.

I didn't want to do any hard methods, scared of bricking it. Updating the OTA over SD card isn't working (can't even find the setting)

So what to do?

They are only OTA updates, not Full, so I can't just use dload method to load them up.

I would prefer to keep root, but if I have to reflash to stock, and then re-root, I can do that.

Any other methods I can use? Can anyone with a bit more knowledge help me out?

And of course, more than happy to share the OTA files, one is approximately 3gb (B317) and the other is about 300mb (B320)
