Don't worry, there are ways of getting it unbricked if everything else fails. I speak from experience.

See this thread:

https://xdaforums.com/t/mediapad-m3-hard-bricked-or-hardly-bricked.3801586/

It took me a few weeks of trying things, but if you can open up your Mediapad you can get to a recovery.

I would wait and try some other suggestions in this thread first, they may offer a simpler solution.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
just out of curiosity, how long are you holding power and vol- before calling fail. It may take up to 3 minutes before you get there which seems like 10. If you feel a click where you accidentally let off a button for a fraction of a fraction of a second, start counting all over again. That's just to get fastboot, what you really need to do is put UPDATE.APP in dload folder on root of cleanly formatted sdcard and hold all three buttons until it shows update screen. If it is booting to the screen you showed it will boot to upgrade mode. Don't know if it will install it, but it will boot to it.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] PedroAdamastor:
@tek3195 thanks for your answer, but i already tried that and didnt work. I just tried again for 5 minutes with Power and Volume Down and its always in fast boot loop. What made this boot loop was running the UPDATE.APP inside dload folder. In the middle of the update screen was black for long time... more than 15 minutes. I turn it off, and i got this boot loop when i turned it on again. I was using this version i found a link here in this forum: Huawei_MediaPad_M3_BTV-W09_C233B025_China_EMUI4.1_05013XFX_6.0_Dload. I guess the only way to go its to try to open it and use IDT. But i never done anything like its, i dont know if i can do it without following instructions. :(
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
I would try update.app again with different version. You should make sure you have exhausted all other avenues before opening tablet.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
You aren't out of options so much as it seems you are out of patience. To clarify, you are not in a fastboot loop with the pic you posted, it is just not booting. I don't care if UPDATE.APP is what you think got you in this situation. I believe it probably had a lot more to do with you flashing /cust partition from wrong firmware to device that didn't need it. When I say you should run UPDATE.APP again, what I mean is you should run update.app again not tell me that it is the reason you're where you are. That file and the firmware updating utility is written to check a whole lot of stuff to make sure it doesn't do that. Any files that would cause it to not flash successfully would have been pulled from their servers a long time ago. That breaks it down to a bad download ot operator error. If you are having this much trouble with the simple stuff you probably don't want to try IDT as it can be a tricky endeavor first go around. There are posts in another thread I'm sure you have seen that goes thru recovering with IDT, should still be a video showing IDT setup.

When I try to give you advice, it comes from tried and true experience. If I don't have an answer, I won't give one. My btv-w09 was purchased for parts as a true brick(yours is not bricked). The test points for the device that everybody uses were provided by me after I mapped them out and posted on numerous sites. I also own a SigmaKey Huawei Edition for servicing these tablets. I'll say once again, use a freshly formatted sdcard, place a different version of UPDATE.APP in dload folder on root of that card then hold all three buttons until it boots the update screen. Leave it alone and watch progress so if it fails you will know where. Keep it on a charger cuz if battery is below 20 or 30% it won't flash.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
His device it's soft bricked because update.app was forced interrupted and maybe one or more partitions are now corupted, and he didn't mention this on the first post. So his device is not soft bricked when he tried to install LOS, so this should be very clear.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
Force interrupting a firmware update falls under operator error, not fault of update.app. I agree with more than one partition being corrupt. I have a hard time believing it wont go into fastboot or erecovery, but if that's the case, no fastboot, no twrp and no erecovery what would you suggest other than UPDATE.APP with a hot battery ?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, it's worth to try dload method with a proper update.app !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] geoffwdixon:
im just a beginner but got myself outta trouble a few times now. Here is my non-trained thoughts.

1. When I have trouble getting into TWRP i find it is because the USB is plugged in still. Only after unplugging the USB and then holding down constantly on the volume up + power buttons until i see the TWRP screen do i then let go of the buttons.

2. last year when I was trying to get back to stock and I couldn't get anything to work, i think i tried a program called SP_Flash_Tool_v5.2020_Win

This worked and got my stock back on first try.

Please remember I'm only a beginner so please do some research if any of this is of use.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Incomtus:
Installed the last update and zoom meeting working again! That's impressive !cool
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] PedroAdamastor:
Thanks @tek3195 and @surdu_petru for all the help. Unfortunately i havent found a way to fix this tablet.

I did all the things you said to do but nothing is working.

No fastboot (tried for hours Power+Vol Down or just Vol Down and connect the usb to PC)

No TWRP (Power + Vol up not working)

No update.app (Formatted a sdcard, and tried it with 3 different versions (folder dload with update.app) and Power+Vol UP+Vol Down not working)

The tablet is out of battery and doesnt charge. Only starts the boot loop when i connect to computer or charger.

Tried to leave it connected to charger all night and it just loops that boot screen i posted before, no charging.

I read that for the dload you need at least 10%, and i have 0% now :(

Tried to follow this post, but i cant go out of this boot loop.

https://xdaforums.com/t/no-os-relocked-and-now-bootloop.3836286/post-77515890

I want to ask you if you have any other ideas on how to charge it to try to save this tablet.

Thanks a lot for all the help.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
I don't like to recommend board software as it is the absolute last option, also the more difficult and increased risk of hardware damage. However, it kinda sounds like it may be your only way out. Battery doesn't matter, it flashes with batt disconnected anyway. Be extremely careful pulling display and use heat and/or alcohol at top and bottom. Afterward make sure to follow up with UPDATE.APP and then the localization files that go with it. You rename it to update.app and go thru project menu for sdcard update. If you don't rename and flash the second one you will have issues. Good luck.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Just to be clear, because I have lost track of it in all of these posts, have you tried to reflash the original Huawei software?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] thunderz1:
@surdu_petru,

I realize this is out of scope but a great feature in Android 10 is Freeform windows and would be great on the 8.4in screen. I was able to enable this feature however when windows are moved or resized every app I have tried crash. If this is something you would like to look into I have a few logcats I can share with you.

Thanks again for the incredible work!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
As I understand, his device is not responding in any way , that means no way to put the device in fastboot mode, twrp or flash update.app throught dload method !

This can happen when you forcibly interrupt the update.app installation process as he did - ( he did this error because at some point from unknown reason the process just stopped as I understand from his explenations )

It seems that some partitions are corrupt at this time so the device no longer responds to any commands - to exemplify , it would be as if we removed the external microSD card while copying something on it - you will immediately see that card it is unusable .

I suspect that in these conditions the only escape would be to try this thread by tek3195 !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, but this feature still seems to be experimental ... I already tried on other tablet with LOS 17.1 and I have the same behavior !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] thunderz1:
Understood sorry I should have done more research and did not realize it was experimental. Suppose should have known since it is under developer settings. Thanks for the reply!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] MattP410:
I know this is a very trivial question, but has anyone else had a problem with Reddit not playing videos within the app? Everything else functions normally, and the videos did too until one of the last two LOS updates. Other than that, everything else is perfect.

Developer,is it possible to flash twrp for Linage directly from twrp for emui?

I am on stock emui 5 b311, rooted all works good, want to try your lineage 17 or 15 not important...

Just if possible to flash this twrp from grealson twrp as img?

Thanks
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] sergio_sant:
Yeah, it's been happening to me since first release of LOS 17.1
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I don't know, I never tried in this way .... but you can try and if it's not working, just install twrp via fastboot !

do you have a md5 hash for the new release? Or could you upload please to androidfilehost? I'm facing lots of download errors in XDA board. (I'm afraid of flashing a corrupted image ending with a broken partition)

I know lineageos is supposed to work without gapps, but I ask the question lol, is it easy to use that ROM without gapps? I mean if install apks that use google account, does it will crach or something? Sorry for the noob question.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Ok, uploaded right now on androidfilehost !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
Yes, it's fairly easy. I have mine running without gapps now. I just use Aurora Droid and Aurora store rooted with Magisk. No MicroG and even Netflix works installed with root installer from Aurora store.

There are some apps that won't run without google services and most that say they won't run without it you can ignore warning, just tap the screen instead of hitting ok on toast and they run fine.

Thanks a lot to @tek3195 and @surdu_petru .

After doing things wrong i bricked my tablet, its was my fault, i did something wrong in the process.

The tablet was not responding in any way , no fastboot mode, twrp or flash update.app throught dload method. Battery was gone too.

With the great help of @tek3195 and @surdu_petru i followed this thread:

Hard bricked or hardly bricked?

I followed all the instructions and i opened the tablet and with the sharp tweezers i have short testpoint to heat-shield with qr-code, had to install the drivers to get the device into Huawei USB COM 1.0 mode (on Device Manager).

Followed all the steps of the @tek3195 video and with IDT i flashed BTV-W09C500B303_Download.xml

SUCCESS 🎉🎉🎉

Device is alive again!

Thanks a lot for all the help.

It started with a chinese version and its charging again.

Its EMUI 2.0, Android 4.3 (Model number and build number unknown)

Now i want to finally install LineageOS 17.1 😃

But want to ask you for your help so i dont mess up again.

What should i do from here?

Thanks again!

Install Android 6.0 EMUI 4.1 ROM with localization files. Boot it and set it up for a brief run. Then update it with an Android 7.0 Rom including localization files and run setup again. Then follow surdu's install instructions for LOS from the LOS thread of your choosing. Make sure to download and flash correct twrp from the thread for the version you are installing. You should be good to go with it then. ****sure feels good getting one back from the dead doesn't it ?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
It works if you have Greatlson's emui5 twrp installed but not with his emui4 twrp. You will have to format /data.

I had not checked if video would play in netflix, only that it installed and opened. I opened it to check for video after seeing @MattP410 post and I had video. Connected to PC to run logcat and see what was happening with video in Reddit. video worked all of a sudden, I don't know what was triggered by opening netflix but afterward videos work in Reddit. Also, I am not using google services or microG at the moment. You may try installing netflix and see how it goes.

Anyone has firmware or knows where to download for Huawei Mediapad M3 8.4 BTV-W09

I need:

Android 6.0 EMUI 4.1 ROM with localization files

Android 7.0 EMUI 5 ROM with localization files

(Dont know what localization there is , im from Portugal. Europe? Global Internacional?)

Anyone has this files?

Thanks 👍
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] MattP410:
Worth a shot. I'm running Gapps and MicroG, so I don't know if that will affect it. I'll definitely tried what worked for you thought. Thanks!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:

Only a chinese version in that website and is offline.

thanks, have to continue the search.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
I don't know if it will make any difference but my netflix was installed from Aurora store with the root installer. On my Tab S5e Play Store won't let me install it but I can with aurora, so there is some checks that it bypasses. Keep in mind all my apps including Reddit on the BTV-W09 are from aurora. But it works on others I own with and without google.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] MattP410:
I wasn't able to download Netflix from the Play Store until I installed Riru Magiskhide Enhancer module, but then I was able to get it. I just haven't seen if it would play yet. All of my apps came from the Play Store. I just learned of Aurora last night, and may be transitioning to it.

First thing, did you clear cache and dalvik before you rebooted from TWRP? second, you are going to have to register your device with Google in order to fix the play protect problem. There are posts concerning how to do that in this thread but I don't remember how far back.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
I believe the play protect crap is normal, I don't have google services on mine so don't know much about it. Search this thread and you will find it. Don't know that imei would cause that but can't remember what was the culprit in the past. Someone in here should be able to help.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] heybrouwer:
Hello, this is a layman from Holland. How are you guys doing?

I followed the instructions to install Lineage 17.1 and open gapps on my BTV-DL09, but it is only functioning partly.

After a lot of hours trying ( the consequence from a Layman) I get it to work , but with a few apps. Google Play can be installed, but does not work, app stops every time. . So will every app that I download form the net. The opengapps were not installed, I got a lot of red lines in Twrp.

Can somebody tell me how I can go back to the old situation with the standard software and android 7?

If I restart I get it in the TWRP or in the restore menu, changes everytime,

An clear explanation how to reverse everything will be highly appreciated.

I will stay a Layman and don't get involved with this technology anymore, I saw a chance to get android 10, but it is too complex to handle

Thanks in advance

Thanks Guys, this was the problem with Lineage 17.1

The open gapps didn't go that wel yet. but that's for later.

Thank again for the quick help, champions
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] heybrouwer:
Since the Lineage was working I decide to keep it for the time being.

I did do the open gapps, for which the system only accepted "open_gapps-arm-9.0-stock-20210327" De rest came with objections from to .little memory space or the wrong version. So it did the install from the gapps correctly with no comments,

But know the tablet restarts and stay in the Fastboot & Rescue screen. and I cann't get him out of that modus. Without the install from tje gapps he seemed to be operating normal without the apps of course. Can you help one more time ?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
You should install GApps for ARM64 not ARM ! .... also you should choose Android 10 if you use LOS 17.1 - from which I see you made both wrong choices and then you wonder why it doesn't work :)

Finally you can also choose "pico" version to avoid any memory space issues !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] heybrouwer:
Thank you, so far so good ,installed Lineage 17.1 and open gapp 10, pico en it works, But there is one problem, tablet is not accepted for Google apps
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:

[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Don't worry, flash again into TWRP the Lineage OS 17.1 and Gapps , that will fix your issues. After that try again to register your device.

Thank you soooooo much!!

I cannot express how my son is excited toward this OS. The tablet now looks much smoother and cleaner than EMUI OS.

I have also rooted the tablet and were able to install AdAway, the ads were driving my son crazy, but not anymore.

I hope you can fix the camera issues anytime soon.

Really appreciate your works
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] heybrouwer:
You are the Champ. It is working now. I did the above, but for the Android_id I had to use Device ID app, which worked perfectly. I submitted the codes Android Device ID and the Google Service Framework. I did that about 3 times when nothing happened and after maybe 10 min. the google play start working en you have acces to all the apps. I tried several times with ADB, but no way that was working. It kept coming back with "inaccessible or not found." So the app was the solution Thank you so very much for your help.

Afterwards I changed too Lineage 16 with opengapp 9.0 nano, because I was missing the camera and I want it for Streaming.

Is it wise to relock the bootloader ? Is the tablet vulnerable with open bootloader ?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] 30adi:

[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
Magisk had a few changes recently, follow the Magisk install guide and you will be fine. I would leave bootloader as is. It's only vulnerable if you will take it where someone would steal it and know how to exploit the unlocked bldr to acquire your info. Yes that could happen, is it likely, hhmmmm not very.
