Hi KonstaT, I had some time to revisit issue with bluetooth working at the same time as GPS and found a way to get it working. Bluetooth stops working as soon as ttyS0 use for console is removed from cmdline.txt. The following dmesg logs shortly after boot suggest console is taking over ttyAMA0.

Dmesg - tty use clean image

[ 2.040482] Bluetooth: RFCOMM TTY layer initialized

[ 112.773323] ttyAMA ttyAMA0: 11 input overrun(s)​

[ 114.557648] ttyAMA ttyAMA0: 17 input overrun(s)​

I'm using a Raspberry Pi 4 model so I can avoid this issue by leaving ttyS0 to be used by system console. I completed the following to enable additional UARTs as per raspberry UART documentation then setting GPS to use uart5 which mounts to /dev/AMA4.

Enable one or all UART in boot config.txt. I enabled all because some UART may have hardware conflicts i.e. uart 0/1 used by Bluetooth and Console automatically.

dtoverlay=uart2​

dtoverlay=uart3​

dtoverlay=uart4​

dtoverlay=uart5​

Change tty used by GPS in vendor build.prop. Any available ttyAMAX can be used.

ro.kernel.android.gps=ttyAMA4​

ro.kernel.android.gps.time_sync=60​

Finally set GPS permissions in ueventd.rc by adding line.

/dev/ttyAMA4 0660 system radio​
[Raspberry Pi Original Development] startechi:
There is another issue where Bluetooth audio breaking up caused by turned on location services which has been mentioned in other posts. I've tried disabling all bluetooth location settings so I can use GPS and bluetooth audio but no change. The only option at the moment is either using bluetooth audio or GPS. Has a fix been found for this issue?
[Raspberry Pi Original Development] Spielmops:
There seems to be an issue with the TTS-settings. If I click on Settings/System/Language & Input/Text to Speech, the settings-app crashes, regardless which TTS-engine is installed. Searching for this issue got me this: https://gitlab.com/CalyxOS/calyxos/-/issues/354

If i understand correctly, this is not added to Android TV version, only to non-tv version? Because it is not working on Android TV version, while it works perfectly on LibreELEC for RPi. I didnt test on non-tv version. I specifically installed Android TV version, because it made sense it would logically be supported on TV version first :)

Big thanks for your great work.

Thank you very much. Will try later!

I changed the GPIOs 20 and 21 to 23 and 24 and that works. It must be a hardware-failure. I'll send the Raspi back ...

How about TTS?
[Raspberry Pi Original Development] s4goa:
speech out put works. all in all very impressive. real cool stuff.
[Raspberry Pi Original Development] alex25:
Maybe a dummy question. Is it possible to use a connected USB camera as the main camera? Such that Android apps use that camera as default?
[Raspberry Pi Original Development] s4goa:
haven't tried yet.
[Raspberry Pi Original Development] s4goa:
tbh, some stuff works, some does not. "fishing clash" game: no workie.

telegram app: slower than usual but works.

1. su is not needed, just enable ssh as in readme and add public own key in /data/ssh/authorized_keys

[Raspberry Pi Original Development] Spielmops:
I got a new Raspberry Pi 4 and I installed the new version from 07/20. The GPIOs 20, 21 and 26 are working now with this new device. But first I thought, that the volume GDIOs would not work, because no volume sliders appeared, when I clicked volume up or down. A headphone made clear: volume control works via hardware-keys, but the sliders do not appear.

Next: Text to speech is working, but I may not recover the data-partition from the earlier version of LOS. It seems, that there are setting which are not compatible. Thus I have to install everything again.

By the way: my display is now a WaveShare 9inch QLED Quantum Dot Display, Capacitive Touch, 1280×720. Works good out of the box and has great colors. It' not cheap ...

Spielmops

Edit

Curious: if I play a notification-sound and while playing press the volume-keys then the volume-slider appears ...
[Raspberry Pi Original Development] s4goa:
not cheap, not compact and not a fone. but works and can be backupped easily.
[Raspberry Pi Original Development] s4goa:
also, on LOS 18.1 as well as OmniROM 11 I do get SD-card filesystem corruption unfixable on a sort of regular basis.
[Raspberry Pi Original Development] s4goa:
I had always been wondering about the funny behaviour of F1 ... F5 keys.

OmniROM-11 has better visual prompts for these things. maybe kang it from them... better usability there!
[Raspberry Pi Original Development] s4goa:
Android does not have a general usb-cam driver like windows has. therefore, most - if not all - usb-cams are not supported. maybe someone makes a driver that works with most cams by way of some magic.
[Raspberry Pi Original Development] s4goa:
c’t magazin claims that the only way to achieve reliable SD card operation on a Pi4 is to make the SD card READ-ONLY. Behind a paywall they explain how to set that mode of operation, which can be switched to RANDOM-ACCESS on a manual basis.

I hope to achive fewer ext4-fs corruption by running on minimum CPU clock of 1.5 GHz instead of 2 GHz. Gonna keep you posted in here...
[Raspberry Pi Original Development] Spielmops:
Most Webcams are supported, but instead of working out of thr box like with normal linux you have to reboot.

GPS: the same.

Spielmops
[Raspberry Pi Original Development] s4goa:
that is not reproducible on my pi4
[Raspberry Pi Original Development] Spielmops:
What is not reproducible? "Most webcam" or "reboot"
[Raspberry Pi Original Development] s4goa:

I have 4 different cheap (<15€} webcams for surveillace and as dashcam. All are working ootb.

anyone have directions on doing this?....i tried installing htchome-2.1.cab and restarted but it froze my screen and wont let me connect to activesync so i am reflashing as i type this.....any help would be appreciated please
[Mogul, XV6800 ROM Development] SimpTheChimp:
I tried it also (twice) and basically had the same thing happen to me also. Once it resets it tries to go to the Today screen; then my ActiveSync screen pops up, I get an error message from Voice Command, and then the phone hangs.

I use iLauncher and it has a 'safe boot mode' so I used that to uninstall the HTC stuff. Once I did that the phone worked fine again. Otherwise I would have had to do a hard reset :(

Here is a collection of files for the BTV-W09, BTV-DL09 and BTV-L0j. They are somewhat organized and contain firmware, board software, roll back packages with instructions and a poor quality un-edited video of how to flash with IDT successfully. The image for test point location is good for w09 and dl09. I don't know if they are the same on the l0j from Japan or not. Should you truly need a file for the BTV variants of the M3, leave a reply to let me know what it is and I'll see what I can do.

DISCLAMER:

There are other Huawei firmware and board software within this thread. Any use of them is at your own risk, although if you're here you've already screwed something up, whether you believe yourself to be at fault or not.

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.

Please, do you have the same files for BAH-AL00/BAH-L09 ?

I have been struggling for a few months to repair my tablet but I didn't find anywhere the right file ( prog_emmc_firehose_8937_ddr.mbn ) for my tablet .

Or I can use the files from CPN-L09 ?

Thank you very very much in advanced !
[Huawei Mediapad M3 Guides, News, & Discussion] surdu_petru:
tek3195, I already tried with CPN files but I have always error with :" Sahara protocol error" , "Uploading Image using Sahara protocol failed" ... I'm using QFIL as administrator with Antivirus disabled & Airplane mode enabled on my laptop and nothing changed about Sahara protocol error, and even I used "emmcdl.exe -p COM5 -f prog_emmc_firehose_8937_ddr.mbn -x rawprogram0.xml" - also without success !

Anyway, I think the battery is close to 0 and there are very poor chances to repair it.
[Huawei Mediapad M3 Guides, News, & Discussion] Barahir's son Beren:
Hi!

Thanks for your quick reply. I need a working solution to take back to factory firmware. I tried it many times, but I haven't succeeded, I always got a recovery screen or bootloop. Is it possible with your files and method?

Beren
[Huawei Mediapad M3 Guides, News, & Discussion] surdu_petru:
Sure, you have all what you need there, just use Qualcomm Flash Image Loader ( QFIL Tool )
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
I wouldn't try cpn on bah, even with same firehose loader it shouldnt work.If it did flash it may make a hard to recover brick.

I can get BAH2-AL00 or BAH-L09. Which one would you like ? I can't find one for BAH-AL00
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
I haven't flashed qualcomm in a while but the error may be from wrong software if using CPN on a BAH. Anyway, I can get BAH-L09 and Iwill have to dig around and find another tool for flashing Huawei/Qualcomm. I hve it but can't remember the name of it right now. It's a lot simpler than QFIL.
[Huawei Mediapad M3 Guides, News, & Discussion] surdu_petru:
On the back side of my tablet it has a label and it says BTV-AL00, but on the settings the menu it says BTV-L09 !

Anyway, I guess I can't recover my device as battery seems to be almost empty and when the QFIL start to make some operations, the device seems to turn off frequently ( at least the drivers keep disconnecting and reconnecting itself )

Thank you very much in advanced !

EDIT:

I managed to brick my device by flashed a wrong TZ.img via TWRP !

I know it was stupid of me, but now I have nothing to do with it!
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
Is it BAH-L09 or BTV-L09 ? I have bah-l09 uploading now, it has board software and a rollback update.app in it along with other release documentation. I can't remember if the Huawei tool I'm looking for needs battery or not. Seems like it flashes without it.
[Huawei Mediapad M3 Guides, News, & Discussion] surdu_petru:
I really don't know if it's Al00 or L09 .... as I said on the back it has a label with BAH-AL00 and something written in Chinese but the getprop it say : BAH-L09 !

Also it's working with kernel compiled from Huawei BAH-L09 source code ... but this it's not so relevant as also CPN devices are working with BAH-L09 source code !

Yes, we talk about Huawei MediaPad M3 Lite 10 / BAH-L09 !

Thank you very much for your help! Unfortunately, for unknown reasons my device can't stay connected on edl mode - so there is no way to flash something via edl mode !

Tthe device seems to communicate successfully only immediately after it has been connected via usb - in edl mode ... unfortunately, a few seconds later the device can no longer be detected !

Tested with : "emmcdl -p COM15 -info'' - and working only one time ( as soon as the device has been connected ) - and if I tried the same command for the second time, there is no device detected like into the picture !
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
It looks like it is still connected and recognized in 9008 mode even after invalid handle status. Different software to flash it with would be my thought. I am not very well versed in Windows and have a Sigma Key Huawei Edition that takes the hard work out of most issues like this one. However, there are free software that will fix it I believe, it's just a matter of finding the right one and then a version of it thst supports msm8937. QPST or QFIL that I see in background I have never had any luck with other than one Lenovo tablet. I will look for the one tool that I have had good luck with in the past. I can't remember the name but I will know it when I see it.
[Huawei Mediapad M3 Guides, News, & Discussion] surdu_petru:

[Huawei Mediapad M3 Guides, News, & Discussion] Aaron jr:
@surdu_petru

Maybe a software called "Dc phoenix" can help you unbrick your device. My BTV-W09 has also been bricked by flashing the wrong firmware. Even though I send it to Huawei's official service center, it cannot be repair by flashing, and the only way they said was to change a new motherboard. However, I found this software, and surprisingly, it works. This is a paid software, but i think this information will be useful to you.
[Huawei Mediapad M3 Guides, News, & Discussion] surdu_petru:
Yes, I know what you say, but my device have some issue connectivity via USB cable ... so any tools is almost useless now without a proper connectivity !

The device is broken since April 2020, I think it took too long to have at least battery to maintain connectivity ... or maybe I'm wrong, but there is definitely a problem of communication via USB cable ! I have the right Qualcomm USB drivers and also my device is connected via USB on proper port - but unfortunately this connection takes very little - and no tools are able to properly connected to my device !
[Huawei Mediapad M3 Guides, News, & Discussion] Aaron jr:
My device had the same problem, too. I can't charge my device and the computer won't identify it. At first, I thought there might be some problem with battery.

I tried various tools and firmware, but none of them succeeded. After entering fastboot mode, it automatically shuts down after a few seconds because of out of battery, then I gave up to fix this device, because its not worth to waste so much time on it.

After a year, I saw that you were planning to make a custom rom for mediapad m3, so I planned to unbrick this device again. I saw someone discussing this software, so I tried it. I didn't hold too much hope, but because the fee can be refunded if it failed, So I bought it. During the process, my device entered into a strange usb mode that i had never seen , unexpectedly, it works.

I strongly recommend you to tried this software, if it fail, your fee can be refunded.
[Huawei Mediapad M3 Guides, News, & Discussion] surdu_petru:
Already tried but DC-Unlocker didn't recognized my firmware which was giving me by @tek3195, I need a .dgtks firmware in order to working with DC-U, and also it can't be flashed directly UPDATE.APP because my device is recognized in my desktop only on EDL mode, and it looks like DC-U don't allow to write UPDATE.APP on my device via edl mode.
[Huawei Mediapad M3 Guides, News, & Discussion] surdu_petru:
@tek3195, I guess that I need the right firmware for BAH-AL00 because I tried to flash with MobileSea Service Tool, and it complain about wrong programer .mbn !
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
Couldn't find BAH-AL00, all I found was BAH2-AL00 and it is Hisilicon and not qualcomm. It's weird the way they have models with two totally different chipsets and still MediaPad M3. I'll dig around and see if I can find anything in a different place. You could see upon opening what I had where it came from and they usually have everything available. I use Sigma Key and they have instructions for repair with board software from a sister device when you can't find exact match. Like using BAH-L09 for BAH-AL00 when exact match isn't available and it will flash UPDATE.APP in several different modes when there is no board software. If shipping wasn't so expensive I'd say send it to me and I would fix it for you. I can't use it remotely, they have it programmed where it won't work that way. I can't even get it to run on a VM in local machine.

DC-Phoenix firmware, software and customisations

DC-unlocker is universal, fast and easy to use unlocking tool. Supports Huawei, ZTE, Sierra Wireless and other modems, routers and phones.

www.dc-unlocker.com

Here is the place where you can find your device's firmware, but this format of firmware only support DC Phoenix. BAH-AL00 is in the supported model list, and the firmware of your device can be download in the website, the premise is that you bought the DC-Unlocker.
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
That may work, DC-Phoenix is good but the firmware is in UPDATE.APP that they encrypted or formatted with proprietary format. It is not full board software but a lot of times UPDATE.APP is fine if you have a way of flashing it, which DC-Phoenix does. @surdu_petru It's worth a shot, may need to ask in their forum about connecting with no battery. They're pretty good about refunding if it doesn't work.
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
@surdu_petru did you try all four of the firehose_loader.mbn files that were in the bah-l09 board software ? there is regular and lite, both validated and not-validated in there.

Also the AL00 is Snapdragon 435 and the L09 is Snapdragon 430. If getprop gave you L09 that is what you should use which is msm8937 and not msm8940.
[Huawei Mediapad M3 Guides, News, & Discussion] surdu_petru:
I've already bought credit to use DC Phoenix, but it doesn't seem to find a way to flash firmware in edl mode. Somehow it accept downgrade update.app but doesn't seem to work on edl mode either. As I can see DC Phoenix accept only dgtks format firmware.

Yes, I tried with msm8937_ddr & lite.mbn and also emmc_apsboot.mbn but I didn't checked with validate .mbn

Edit:

tek3195, do you know if I need to change .mbn program name also on sahara.xml as is just a generic one there ?
[Huawei Mediapad M3 Guides, News, & Discussion] tek3195:
That's one thing nice about Sigma Key, it takes .skf proprietary format but also will flash UPDATE.APP, .mbn and .xml firmwares
[Huawei Mediapad M3 Guides, News, & Discussion] surdu_petru:
Ok, thank you very much for all your help !

DC-Phoenix can't detect my device on edl mode ... always says he didn't find anything in download mode & and a lot of others options are for flash in fastboot mode, which is incompatible for moment with my device as there is only edl mode for my device at this moment .

I tried also all 4 firehose .mbn and also emmc_appsboot.mbn and no one passed whatever the tool I use !

So, if you can help me to flash it locally I'll try to send you my device ... please send me via PM your address details, thanks !

There is absolutely no problem if you do not manage to fix it, I just ask you to give it to recycling !

Anyway, thank you very very much in advance for your help !
