Request if you have latest Full BTV-W09 US rom? I finally unbricked my M3 using the US rom posted. However I can't update to the latest stock rom. Stock on emui4/andriod 6. Tried using Huawei firmware finder and they're all no longer on the servers.

hello,

I am trying to root my bah-w09 c100b257. I am looking for the stock rom to patch the boot.img with magisk but cant't download from update.hicloud.com ("an error occurred" html page is all I get...).

Does someone have it?

I thought I could just flashboot boot twrp.img and then do a backup and feed boot.img to magisk, but it doesn't boot. Maybe wrong twrp image, but i have tried multiple...

I am afraid to flash twrp as I am not sure which version is suitable for my device/version, as they don't boot with flashboot boot.

Can somebody help me?

Thanks!

Hello,

I am trying to root BAH-W09 C100B257. Already boot unlocked.

I can't find stock rom (update.hicloud throws a "an error occurred" html page). I need it to patch boot with magisk.

Does anyone have it?

Otherwise I thought I would boot with twrp (fastboot boot twrp.img), backup stock rom, and then patch boot. But twrp images I have downloaded don't boot... Maybe wrong twrp img for device/version... Anyone can confirm version I need? I am afraid of flashing twrp wihtout having a stock rom and being sure of what image works...

Can anyone help me?

Thanks!
[Huawei Mediapad M3 Guides, News, & Discussion] surdu_petru:
There is no twrp for your device in order to be used with stock EMUI firmware to be able to "root" your device !

EDIT:

You can check the LOS 16.0 Thread for your device if you want to learn more stuff !
[Huawei Mediapad M3 Guides, News, & Discussion] lolailo98:
Thanks for your answer, now the messages saying this twrp for android n, this twrp for android pie suddenly make sense! I could'nt understand because stock is android 7 ! (I read that in the LOS and twrp threads) So there are versions of twrp denpending on what LOS version you want to install, pigé!

I'll try to install LOS. But how can I go back to stock if anything goes south? I can't find the stock ROM... Or I should use the files you posted in this trhead for bah-w09? I don't know anything about this systemboard files...

Thanks!!
[Huawei Mediapad M3 Guides, News, & Discussion] surdu_petru:
That's why I told you to check the LOS 16.0 Thread !

Please take the time to document yourself very well before moving on to LOS !

I think two days are enough to go through the two threads LOS 16.0 & LOS 17.1

does anybody have a stock rom for BAH-W09? thanks a lot!
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
BAH-W09 @mc_simon88 let me know how this works for you. I believe there is board software available also.

Board Software BAH-L09 The board software for w09's is the same as the l09's. When flashing you have to omit or deselect modem partitions and a couple others. You can search SigmaKey for flashing sister firmware to find exact partitions to be excluded. It is the same whether it be Sigma or DC-Phoenix or any of the others including IDT. Not that @mc_simon88 needs it now, but for anyione else that may go looking for it one day.

DISCLAMER: Flashing board software is a last resort and should not be done unless all other methods have been exhausted. Only flash board software when there are no other alternatives.
[Huawei Mediapad M3 Guides, News, & Discussion] mc_simon88:
maybe you can upload the board software aswell? thanks!
[Huawei Mediapad M3 Guides, News, & Discussion] mc_simon88:
I need this rom for DC Phoenix, flashing/unlock testpoint mode
[Huawei Mediapad M3 Guides, News, & Discussion] mc_simon88:
You are my Hero :-). My Tablet is Back on Stock now!
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
In process of uploading board software now, but looks like you don't need it. Glad to hear you got it going.
[Huawei Mediapad M3 Guides, News, & Discussion] danielsann:
Hi

I'm searching CPN-W09 stock rom.

could you please help me?

Thank you
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
This is only one I know of CPN-W09
[Huawei Mediapad M3 Guides, News, & Discussion] danielsann:
Thank you so much for your reply, but I need the stock one to recover my tablet that is died, I have to put the stock rom with Qualcom HS-UB COM port . I don't know if it possible also to put a custom rom :(
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
Ahh, you didn't say that at first, you just asked for custom rom. I got you, or should have you anyway. Give me 2 or 3 hours to get it and upload it. What region do you need ?
[Huawei Mediapad M3 Guides, News, & Discussion] danielsann:
Really sorry, my mistake, I need the stock rom , I'm in Italy !! thank you so much
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
Do you know which you need there is cpn-w09c100b261, c100b260, c100b277, c331b277cust331d001, c233b070, c100b253, c331b003
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
@danielsann here are a couple of stock roms. I will post board software once I get it unencrypted.

[Huawei Mediapad M3 Guides, News, & Discussion] danielsann:
Hi

unfortunately to upload the stock firmware through Qualcomm HS_USB com port, I need .xml file of firmware .

My tablet doesn't poweron in this moment only Qualcomm port is available .

thank you
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
It should be in the same folder in link provided. Look for board software folder and that should be your .xml based firmware files. I didn't unpack it to check but that should be it.

ok I just looked at them. You need to grab the .zip file from the board software folder. The .rar file is board software in update.app format. The .zip file has the firehose and rawprogram.xml that you need.
[Huawei Mediapad M3 Guides, News, & Discussion] danielsann:
Oh yes , I see it , sorry for my questions, but I'm not really expert, do you have the procedure for recovery ? If I well understand I have to use QFlash software where I have to select the Qualcomm port, select the xml file and after upload the firmware ?

thank you again
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
It wasn't there when I first uploaded others. I haven't unbricked a qualcomm in a couple of years but yes Qflash or QPST or a handful of others for Qualcomm devices. If you look in link for BTV variants in this thread there is another tool that worked for me when I couldn't get others to work. I would first look at guides here in the forums for how to flash it as I'm rusty on it and wouldn't want to mislead you. If you run into any problems feel free to ask and I'll try to help you with what I can remember.

EDIT: I forgot where they were. The tool is in same folder with CPN-W09, you probably seen them already.
[Huawei Mediapad M3 Guides, News, & Discussion] danielsann:
Really thanks !!!!

I'm reading from the beginning of thread !! :)
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
@danielsann if you look here there is a list of qualcomm tools at the bottom of page with instructions for all of them. Maybe it will help.

go to bottom of page under alternative tools for list.
[Huawei Mediapad M3 Guides, News, & Discussion] danielsann:
Hi

I tried several times with several tools suggested but I received the same errors every time .

For example using Huye Download Tool I received message : Fail => QLIB_QPHONESMS_Sahara_FlashProgrammer

With Qflash tool ( every files selected in the firmware dir ):

with QFIL :

Qualfast :

Obviuosly I see the Qualcomm port :

Please help me :( I don't know what other things I have to do

many many many thanks !

[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
Try this one and see if you have any luck. On a lot of them there seems to be an issue with Huawei interface even though it is a qualcomm device. This one is made by Huawei so maybe it will work. There are detailed instructions step by step on same site. It says fastboot or download mode so not sure if 9008 mode is what they are calling download mode or not. Finding the Huiye tool to work with a KOB-W09 took me a long time and going thru a lot of different tools and ultimately having to edit some files to get it to work. It is trial and failure with a lot of googling the tool name with the error you get. It can be a tedious pain in the assets. I've had devices that I spent 2 months looking for a solution to unbrick. You just have to keep at it, or buy some paid software. For Huawei I have a Sigma Key Huawei Edition that works well enough I bought my MediaPad M3 off of ebay as a hard brick for $35 with no doubt I could fix it. There are cheaper solutions than Sigma like DC Phoenix if your device is on their support list it will work or you get your money back. I think last time I used DC Phoenix it was like $20 for 72hr license, but that's been a while. Sorry I can't be of more help, if it was local it wouldn't take 10 minutes and be like new.

Just looked and DC Phoenix supports your device and has the firmware files for it. It was $19 for 72hr license.
[Huawei Mediapad M3 Guides, News, & Discussion] danielsann:
Sorry for queustion , I have no problem to bought 19$ of license if it works !

But , my question is : is it possible that I have this kind of problem because my tablet is stock and the bootloader is locked ?

Is it possible that I have to use the testpoint to enter in EDL mode ?

thank you
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
When you are seeing Qualcomm HS-USB QDLoader 9008 you are in download mode whether bootloader is locked or not. I don't have same device to check modes but Huawei does have some that are different. 9008 mode, EDL, Download mode and a few more are all doing the same thing just a little bit different from OEM to OEM. I had mentioned something earlier about it could be a pain working with Huawei interface on a Qualcomm. Qualcomm tools are hit and miss with which ones work with Huawei. When I said I looked and DC Phoenix had your firmware, that meant that they have your firmware in their proprietary format that works with their software. Same way all of them do it, Sigma Key has an .skf extension on their firmware files for sigma key format. Each tool vendor that uses proprietary format has it so you can't use there files with other tools or other files with their tool. Luckily Sigma finally let us start flashing UPDATE.APP and .xml files in addition to .skf. Anyway, DC has your firmware so it should flash it. I would go on DC-Unlocker/DC-Phoenix forums and make sure it will flash in 9008 mode and not just fastboot. Make sure to have unbrick solution planned out before buying license, if you run into problems that 72 hours can disappear quick waiting for help on their forum. If you don't have an issue with the $19 go for it.

I have run into problems navigating their sites. DC Phoenix and DC-Unlocker are the same but different. Finding downloads and making payments can be frustrating at times. About time you get your head around the fact that DC Phoenix is seperate from DC Unlocker and is not HCU Client you have to go to DC Unlocker to pay for DC Phoenix. Again, it should work for you. Good luck and let me know if you get stuck.
[Huawei Mediapad M3 Guides, News, & Discussion] nkven:
Hello!

Is there someone that has the board firmware for BAH-W09? My tablet is stucked on EDL mode:(

I would appreciate it! Thanks!
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
BAH-W09 does not have its own board software, it is shared with BAH-L09. Post #14 in this thread should have it in there as BAH-L09 which is what you have to use. You omit or delete LTE related files to flash wifi variants. If you search 'Sigma Key, flashing board software of sister device' they have a list of which files to flash or omit.

I didn't see the old instructions with list. Put this here for #1 as #2~5 are specific to Sigma Key

How to repair your phone if there is no factory flash for your exact platform:

Select flash for other platform, but based on the same CPU (for example, factory flash file for EVA-AL10, EVA-L29… can be selected for EVA-L09)

Select profile “Don't flash” and flash the phone.

Bootloader will be downloaded, but nothing will be flashed.

Then use FLASH via fastboot mode and flash the update.app file that suits your phone’s platform

Repair Vendor/Coutry; IMEI and other numbers

To finalize repair operation flash your phone via UPGRADE MODE
[Huawei Mediapad M3 Guides, News, & Discussion] nkven:
Thanks for the quick response.

I tried using some free other flashing tools with no success. I would like to ask if there is any other flashing tool except SigmaKey or paid software.
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
There are a lot of Qualcomm tools but the Huawei interface seems to get in the way. There are a couple tools made by Huawei and there is Huiye Tool that I have used before but it is version specific as to whether it will support your device. Easiest way would be DC Phoenix, it's paid but worth it for $19 for 72hr license. That is if your device is on their support list.

Just looked and yeah they got you covered. It's pretty good tool for bricked huawei devices. It also allows flashing past locked bootloader which was how I got twrp on a locked T3-7. Took some under hood tweaking of file names but very powerful huawei flashing utility.
[Huawei Mediapad M3 Guides, News, & Discussion] nkven:
I bought 72 hours license but, I could not find firmware for BAH-W09 with file type .dgtks.

Also, I tried every program for flashing board software and it didn't work. It appeared sahara fail error. Maybe, there is not any solution for my tablet.
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
Did you try the ones I showed ? If license is expired contact them and tell them you didn't find firmware and they should extend your time. The firmware in those screenshots should be correct.
[Huawei Mediapad M3 Guides, News, & Discussion] nkven:
Yes, I download and tried. DC Phoenix appeared a message that my device is not into upgrade or testpoint mode. Also, the tablet appeared on my laptop as "Qualcomm HS-USB Diagnostics 9006 (COM3)" and I changed the drivers to "Qualcomm HS-USB QDLoader 9008".

Sorry, I don't have much experience on that.

Thanks in advance.
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
have you asked anyone at DC Phoenix about unbricking from 9006 mode ? there are tools to go from 9008 to 9006 but I don't know if they work the other way around. I would check with DC and see what they know.
[Huawei Mediapad M3 Guides, News, & Discussion] nkven:
Unfortunately,no. Maybe it needs to be in testpoint mode in order the firmware to be flashed.
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
You need to ask them since it is not marked as supported for using test point. The only one that I know of that is supposed to work from 9006 mode is EMMC Dongle, from trying a crack version that connected to device in 9006 mode and was ready to write but I didn't have .xml firmware at the time. There are different guides for recovering from 9006 mode that are complicated and I have no experience using. 9006 is a pain in the @SS to deal with. Keep trying and eventually you'll find solution, somewhere, maybe.

Hi,

I want to sell mit BTVW09 device, so I wanted to go back to stock.

Can I use Huawei eRecovery in any way?
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
Huawei eRecovery has never worked on any tablet I have had. It is built not to work from what I seen from opening it up. It's full of crap that can't work with grossly misspelled addresses and malformed URL and sometimes wrong device info. Had an Huawei/MTK BG2-W09 and the erecovery couldn't recovery anything but Hi-Silicon chipset devices. You can however use sdcard dload method to install stock firmware. If on custom ROM you will have to flash stock recovery and recovery2 images to use it.

fastboot flash recovery recovery.img
fastboot flash recovery2 recovery2.img

after that with stock update.app in dload folder of external sd card power cycle tablet holding pwr vol+ and vol- all at same time. Do not let go of buttons until builtin updater screen comes up. If you have chosen appropriate firmware give it about 5 minutes and you're good to go. Flash android 6 marshmallow for best results.
[Huawei Mediapad M3 Guides, News, & Discussion] Scootch2002:
Yes, I use Lineage OS 17.1 by Pedru. I managed to make this work, but now it seems to be more difficult ;)

First I have to find the recovery image.
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
RECOVERY here you got recovery.img and recovery2.img don't worry about the header files in the zip.
[Huawei Mediapad M3 Guides, News, & Discussion] Aqibjd773:
Hi there i was trying to get back to stock from lineage os 15.1. unfortunately i got my bootloader locked due to update.app file and i am stuck between e recovery and can access fastboot mode too. But my bootloader is locked so i can't flash. What should i do
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
Unlock it again. Even when relocked by update.app the code remains the same as the one you used to first unlock it. If you have fastboot you should have one of the recoveries, try dload with three buttons again.
[Huawei Mediapad M3 Guides, News, & Discussion] Aqibjd773:
I don't remember the code. I unlocked it about 3 months ago.
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
How did you get the code the first time ?

Shouldn't matter anyway, you should be able to use update.app in dload folder of sd card. If that's how it got locked it should still work. It doesn't have to be unlocked for update.app to work.
[Huawei Mediapad M3 Guides, News, & Discussion] surdu_petru:
As I already told you, you mast to have a proper update.app which match your device .... an inappropriate update.app will stop the installation / update process to 5/6%
[Huawei Mediapad M3 Guides, News, & Discussion] rhariliva1:
Please, Can someone share .xml file for cpn w09 ? I'm unable to download Big file in m'y place now. Sorry for my Bad english. Thanks
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
I have them but you will need the other files to go with them. This .zip CPN-W09 is the .xml based board software, the .rar file is update.app. To use the rawprogram0.xml and patch0.xml you need the rest of the files in the zipped archive. It is only 630MB which is fairly small for a firmware file, are you able to download that much ?
[Huawei Mediapad M3 Guides, News, & Discussion] rhariliva1:
can you give me a link for the download other than mediafire?? Because the download speed is too slow on mediafire, 8 hours to download the file on mediafire.

-does the bootloader have to be unlocked before flashing stock firmware??

-with which tools do we flash the tablet?

_why "fastboot reboot recovery.img" command is not working?? Only fastboot reboot and fastboot devices command are working.

-

Sorry for my bad english
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
There should not be anything throttling download speed from my mediafire account. I just downloaded it with Xtreme Download Mgr and it took less than 20 seconds.

The bootloader does not have to be unlocked for stock firmware. Stock firmware has factory signed images which is what the bootloader checks for and does not allow unsigned img files.

Which tool is an interesting question. What state is your device in ? Do you still have erecovery ? Who told you you needed .xml firmware? UPDATE.APP is the way to go if possible. The .xml firmware is a board software

package usually flashed in Huawei USB COM 1.0 mode. After board software you have to flash firmware thru update.app with localization files and repair imei and serial number which requires extra tools. I use a Sigma Key for flashing mine, but Huawei IDT works good once setup. Board software in .xml format is the last resort for these tablets and should only be used as such.

I am not familiar with fastboot reboot recovery.img, that is not in the list of fastboot commands that huawei has implemented on the device. You can't fastboot reboot recovery and you can't fastboot boot recovery.img, neither are allowed by huawei. I believe reboot and devices are about all they allow with locked bootloader.

Main thing is let me know what state your device is in and I will see what we can come up with.

edit: just realized this was qualcomm and not hisilicon. flashing is different as are the tools but update.app still the way to go.
[Huawei Mediapad M3 Guides, News, & Discussion] rhariliva1:
Thanks you for reply.

Thé state: stuck on "phone activation" , i forgot m'y Huawei id. I bought the tablet in china 2 or 3 years ago, there IS no playstore inside. I've tried to install playstore apk ans Google services, m'y tablet start to bootloop. I've performed a wipe data Factory reset from recovery, and now, i'm blocked on Huawei phone activation.

I've tried Many Times to flash update.app , it Always failed.
[Huawei Mediapad M3 Guides, News, & Discussion] rhariliva1:
I have already tried the update from the sd card: fail

I also tried with various applications but nothing happens.
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
have you looked at any of these vids for bypassing phone activation ? That would be much better than flashing firmware.
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:

The Real deal is : how to install QUALCOMM HS-USB QDLoader 9008 port without running devices? And how to start thé devices to edl mode?
[Huawei Mediapad M3 Guides, News, & Discussion] rhariliva1:
This port Can be installed only on edl mode. entering edl mode requires being in adb. As the tablet is blocked, it is impossible to activate the adb mode. Tried rebooting to edl from fastboot but tablet only reboots.
[Huawei Mediapad M3 Guides, News, & Discussion] rhariliva1:
It's not working. Thanks
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
Well, like I said before board software is a bad idea for solution to locked tablet. But if you insist you can google making a boot cable for it. You can also search key combination for it, should be something like hold vol+ and vol- while connecting usb. It is not that difficult to get into 9008 mode. Good luck.
[Huawei Mediapad M3 Guides, News, & Discussion] rhariliva1:
I already tried to find the key combinations but none worked.. . I tried to do it from fastboot but it didn't work too. FRP videos on YouTube too, my mediapad was bought in China, the talkback menu is in Chinese, and there is no help available like on YouTube videos. Help me please.
