I am still having some issues with Open Camera, even after installing ExSDCard.

When taking a picture, the image just hangs, but I can still use the app like changing the settings.

Making a video is suprisingly working.

I also tested in another photo app, where exactly the same happens.

Any ideas on how to solve this?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Unfortunately portrait mode does not work, try landscape mode to take photos :o
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
Mine hangs in landscape also. I'm not griping about it just letting you know.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Ok, good to know, thanks !

what does WIP mean
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I'll prepare a new update in a few days, don't worry :o

Working In Progress :)

Hic, I'm amateur and I need step by step guide :( I don't want my tablet will be a brick
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Firstly , there is no reason to Quote the whole OP !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] lord_donut:
Thanks!

Thank you for all the hard work and progress! Donated to keep this train rolling!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Thank you very much for your donation !

Yes, I'm almost ready with a new kernel update to 4.3.0 ! There is almost 12.000 new commits/patches from 4.1.23 to 4.3.0 - but for the moment I have some issues with this new kernel ... in fact sometimes the device refuse to boot, and sometimes with the same kernel without any modification, the device sucessfully boot without any issues ! I'll try to fix this issue as soon as possible in order to be able to release a new update with the new security patch and the new kernel 4.3.0 !

[MENTION=2335078]surdu_petru[/MENTION] what all does the cust partition include ? I corrupted mine and played hell recovering from it. About to start over on btv-w09. I know we've tried some different boot.img's since 6-13 but what do I need to flash now for fresh stock tablet, same zip and boot.img from 6-13 ? Or should I set it to the side and wait for update ?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, you should to install the ROM & boot.img from OP !

Better don't wait for a new update as I have some kernel issues and I can't fix them very quickly.

Starting from tomorrow I'll release some kernel tests, because it seems that I'm not able to check the issues on my tablet by my own ... sometimes I have some issues and sometimes all it's working very well, and all this with the same kernel .
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
I'll test with you. That's really about all I do is test and try different things. F.Y.I. a corrupt cust partition can stop you from flashing system or restoring a twrp backup. It can leave it pretty much useless, I'll not use the "b" word.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
We don't use cust partition on LOS 15.1, but if you have issues using this Rom with a corruppt cust partition, I can try to disable the access on fstab for this partition as it's not used anyway.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
You don't have to do that. I removed cust partition line from the twrp.fstab. Waiting for it to boot as I write this and beginning to wonder, should I remove it from fstab.hi3650 as well ?

It just booted, nevermind.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
I would imagine OP knows this but for everybody else:

Just a brief note on going back or recovering. If you use UPDATE.APP that is in upgrade OTA, you must use all zips from numbered folder. If you just extract the UPDATE.APP files you will be left without needed functions. The zips can actually be flashed from twrp. I believe the zips from Team MT database can be flashed via twrp for reverting also. But, whatever you're doing, going up or down be sure use update_data_full_hw_<country>.zip.

Sd Card not working with non-system apps

I can't get anything other than the system apps to be able to have write access to the 64gb sd card I have in the unit.

Things I have tries to no avail:

1. I tried a different SD card

2. I tried to use a root explorer to change permissions.

3. I have given access via the built-in files app to the card.

4. I have formated the card in the tablet and on a PC

5. It is not set to be formated as Internal storage (but when I did the tablet boot looped until I took the card out).

6. I tried partitioning the card in the device

7. I ran the ExSDCard_Write_Access module in Magisk Manager

8. All the apps I have tried have storage permission activated

Other than this bug everything else is great.

Any thoughts on how to proceed would be appreciated.

Please and Thank you.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Read the posts - this is a known issue, and there is no 'fix.' It will be solved when the OP gets the ROM more developed.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
I just copied a file from a backup in /storage/emulated/0/RootEssentials to /storage/6507-11F9/TWRP/ with no issues. I know it was a problem at one point, but is it still ? I don't know what I did diff this time around but mine is writing to external storage with 3rd party apps. Used MiXplorer to copy that file a minute ago if anyone wants to see if it helps.

New Update of LOS 15.1 !!!

Hi !

I'm back with a new update of LOS 15.1 Android Oreo for BTV - devices !

What's news :

- update Android security patch level : July 5, 2020

- Android Kernel updated to 4.2.0 ! ( almost 11500 new commits from stock 4.1.18 )

- workaround to fix sd card permissions, disabled sdcardfs by add on build.prop "ro.sys.sdcardfs=false"

Starting with this update I'll not provide update for the build where fingerprint it's not working ( the fingerprint was disabled in order to be able to root with Magisk ) - so you should keep using the older version from OP if you still use Magisk !

There will be a new update later after kernel will be updated properly to 4.4.0 !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] buntpfotenkatze:
:victory:

Sorry for asking /that/ question again, but my interpretation is, that this fixes internal storage access? Or does it just fix access to external sdcards?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I don't know exactly what issues was reported early, but I guess it was something related with third party apks can't access external storage ... now after this fix / ( workaround solution ), I can download for example a photo from web and it's saved on my device, and also I tested with File Explorer + to copy some files from internal storage to external storage and also create a new folder on external storage and all those operations are working now !

I guess it's also fixed internal storage access, not checked yet, but you can checked and let us to know !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
So far, all working well! New SD card coming in tomorrow, will test that then, thanks!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I don't know if all it will working like it should with this workaround, anyway the final fix will be into kernel after sdcardfs driver will be properly updated :)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Ran Geekbench 5 on this version of the ROM. In the last version, could not complete the Compute test, a number of modules failed to run.

In the new version of the ROM, Single Core 349 Multi 1135, faster than my brand new Galaxy Tab A 8.4 2020 which single core 271 and multi core 965

In the Compute test, OpenCL score for this ROM was 843, better than Tab A 774

Nice work!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Ok, we can't expect right now too much from this kernel at this time update stage as it's only 20% finished .... :)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Running smooth as silk right now for me! Very happy with it... :)

---------- Post added at 12:24 PM ---------- Previous post was at 11:34 AM ----------

OP, do you (or anyone else!) know how to bypass or eliminate the initial boot nag-screen about 'your device is now unlocked and can't be trusted?'

thanks, jf
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
I know it has been removed on a couple of devices and bricked one trying to remove it. It is part of secure boot and would require new bootloader to be written and flashed which most aren't accessible. Bootloader and boot.img are entirely different animals with bootloader being write protected and not part of ROM. There was a patch but the patch only deleted the splash screen images so you didn't see it. You still would have to wait for the delay with just a black screen. Not really worth messing with.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
I mind the delay less than I mind seeing the nagging from Huawei! If it was just a simple image replacement I'd do it in a minute....
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
Yeah, unfortunately it's more than that. The orange state screen is not nearly as bad as yellow or red states. And of course we don't see green state it skips status and just boots. Trying to change it is too risky unless well versed in jtag. It is part of android we have to live with.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] buntpfotenkatze:
As far as I can tell, it fixed it, thank you very much :)

Every app I tried (Firefox, nextcloud, Pokémon TCG) that didn't work with the previous build can now access the internal storage without issues.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
External storage is still not working. Tried a new 32GB card, on formatting as internal storage it rebooted to Huawei 'Recovery,' and would not boot normally. Removing the SD card and it boots OK again.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
External storage it's working, just don't try to format it on LOS 15.1
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
Did anyone happen to notice that after trying to format as internal it shows as adopted storage in twrp ? Also when straightening out sdcard with PC after attempting to partition it mixed 50, there were three partitions so it had the meta or whatever it saves. I also found that a factory reset from twrp and fix contexts in advanced enabled reboot without removing card. Last but not least after setup mine is rebooting every time after Lineage start screen. As soon as I touch start it reboots but reboots to the home screen unlocked ready to go. Like a soft reboot of UI and not system, if soft reboot shows Lineage splash screen, not sure.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
There is only a workaround and not a definitive fix for storage issues and I already mentioned a few posts back when will be fixed, so currently it's not recommended to format external storage into LOS 15.1
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
Yeah, I got you, I was just pointing out some things that were different. Gog any thoughts on random reboots to recovery ?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
So, do you encounter random reboots to recovery or erecovery ? I guess all it's possible ... we should wait a bit for others feedbacks .
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] lord_donut:
Got it up and running. Able to move files between internal and external just fine. No issues to report so far. Fantastic work!.

[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
I have to install e-recovery again. I had twrp in recovery2 slot and then flashed a testing recovery zip which installed that recovery to recovery partition. I've since replaced that test.img with correct twrp so I actually have twrp in both recovery and recovery2 slots. I'll see what it does after I fix that. Oops

Hello from France,

I can't download the recommended version in message 2 for TWRP 3.3.1.

Is it possible to have another download link?

I'm on a BTV-W09. So far it seems to be working with external storage. However, screen rotation is not working correctly. The desktop won't rotate. However, separate apps rotate just fine. I tested in Google Play Store, CPU-Z, and Settings. They rotate fine.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
On your home screen, long press and select settings > more > rotation and see if that does it.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] mrdark5555:

Finally someone created a rom for this tablet, thx [MENTION=2335078]surdu_petru[/MENTION] !

Some questions, is there any way to have the fingerprint gesture temporarily, even with some external app?

Are you going to implement them later?

And, it's normal that there isn't any option to customize the rom? it's too strange to have a vanilla rom on some device, we are used to having a lot of customization
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
What are you wanting to customize that you can not?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] CarloHD:
I meant, maybe there is some customization but due to an incorrect flash it didn't appear to me...
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
I suggest you try a home screen app like Nova - it allows a very large number of customizations.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] CarloHD:
Need help, i try to restore the old nandbackup, i flash my old recovery with which i have maked the backup, but when i reboot on the old recovery, it can't mount data partition... any solution?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
If your old recovery is greatslon's you most likely need to change file system. Go to wipe > advanced wipe > change or repair file system and see what it reports it as.

---------- Post added at 10:42 PM ---------- Previous post was at 10:31 PM ----------

We have more than I used to think with LOS but you have to find them. I mean it isn't like a lot of the customs where you have a settings or tweaks menu that bundles them all together. There's not as many options and then being scattered out makes it seem even less. You're right about Nova, with a couple more you can accomplish just about everything as with Liquid Remix or others that offer too much for me. Can't remember what it was now but there was more with nova as system-app.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] CarloHD:
I tried to format it in ext4, in ext2 with the current recovery (for LOS15) and after flashing the old recovery (yes, it is greatslon's recovery) nothing changes, it isn't possible to access to the data partition (i can't flag on mount menu), then I cannot format it in others types of file systems, or repair . I can only flash the recovery for LOS via fastboot and after the data partition return to work.

what else can i try before i recover everything through erecovery? at least we make sure that the nand method doesn't work
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
f2fs is what it was formatted for with greatslon's mod I believe. Change file system to f2fs and it will restore old backup. I speak from experience as I had to figure it out a while back. Try it and see, it should work. Only /data nothing else.

I may have that backwards it may need ext4 whichever it is it is just opposite with the other recovery. Why can you only flash with fastboot ? Use recovery to flash recovery.

You can forget about e-recovery, it's not even designed to work.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] CarloHD:
With the LOS recovery, data is formatted in f2fs. if i flash the old recovery with the LOS recovery, i can boot the old recovery, but i can't mount data, then i can't acces on data storage from pc because there isn's any storage. Then if i want turn back, i can flash LOS recovery from bootloader with adb/fastboot.

I'll try to change the file system to ext4 and then to f2fs, and then I will flash the old recovery, maybe something changes...

EDIT: nothing has changed
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] CarloHD:
This is a screen of recovery log of the greatslon's recovery
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
Is that greatlson's or surdu's ? I had the same thing happen and had to change file system for it to work. Eventually you will have to lose that twrp backup because they will never sync between two recoveries. I can't remember detailed steps but if you want your old backup with old recovery you will have to change file system and it has to be done in a certain order. Can't remember what that order is though. Whether flash then change or change then flash, use fastboot or recovery for flashing? Can't remember. Unless that backup has something really important I'd let it go and start fresh.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] CarloHD:
Greatlson...

the only way to change the file system is only with the surdu's recovery. when i change recovery, i can't change file system. Why? because the /data partition doesn't mounted and i can't mount it.

then to restore the previous state of the device is to restore the firmware stock, unlock the bootloader, and restore the recovery (and in this case try to restore the NAND)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
Ok surdu_petru has correct /data device as /dev/block/bootdevice/by-name/userdata and greatlson used /dev/block/dm-0 .

When you try to restore check your recovery.log and see exactly what it is doing and you will find what needs to be done. Post the log here I guess, but you really need to use latest twrp by [MENTION=2335078]surdu_petru[/MENTION] if you plan to go forward with this device.

---------- Post added at 12:30 AM ---------- Previous post was at 12:25 AM ----------

That nand will not work with new recovery as they use different mount point. You will need to let go of old backup because it will not restore to /dev/block/bootdevice/by-name/userdata it will only go back to /dev/block/dm-0.

---------- Post added at 12:36 AM ---------- Previous post was at 12:30 AM ----------

@CarloHD there is also the possibility of fixing with nougat OTA if you want. I can post a link to update.app and hw.zip with recovery and recovery2 img's. Flash recovery and recovery2 then load update app to dload on sdcard and force update with three button method. It did not lock bootloader when I did it last.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] CarloHD:
I have not arrived at the step of restoring the NAND, because I understood that I must first put the old recovery back, the problem is with the old recovery I no longer have the partition /data

I know I can restore with dload, but I am trying to restore it with nand, but apparently it cannot possible
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
No, not with that nand it won't be because it looks for /dev/block/dm-0 for data. It is really only good with old recovery.

Will you have to flash stock recovery or will it do dload with just recovery2 ?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Jpwandee20:
Try this update and evething improved

- l can download purchased ebook from Amazon Kindle!

- I can attract image in this post
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] CarloHD:
Well, i definitely bricked the tablet, it won't turn on anymore. I had managed to restore the system with erecovery but during the initial configuration the keyboard did not appear. I have unlocked the bootloader and put the recovery greatslon on, everything worked, so I thought I could restore the NAND . I restore my NAND, and at the reboot it no longer turned on, it shows no signs of life even if I put to charge it... I don't think I wrong any files

I hope that the assistance doesn't ask me too much money to repair it ...
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
You can't mount data because greatlson TWRP required encryption to be enabled. So you need to format data, and try again to restore your nandroid.

Edit:

You don't need to repair your device, it's already working.. just flash the proper UPDATE. APP via dload method.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
/dev/block/dm-0 it used for data encrypted !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] CarloHD:
I have formatted /data many times from recovery for LOS, but every time I put greatslon recovery, the data partition became inaccessible, and since it's inaccessible, I can't format it...

However, now I can't flash UPDATE.APP because I can't access eRecovery anymore, since it no longer responds to any stimulus, not even by connecting it to the PC... I think that it's hard bricked...:crying:
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
I may also possibly just be out of charge - I suggest trying a cable and charger that you 'know' are good (test on some other device) and plug it in to recharge...
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] CarloHD:
The charger and the cable are ok, i've do all the step with full charged device

I think the only way to resurrect it is by using the method of test point, but I don't have the skills
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] mrdark5555:
On a BTV-W09 I've noticed some odd behavior. When I have it plugged in to charge, the screen doesn't always respond to finger touches or responds to a finger touch the wrong way. What I mean by the wrong way is that if you touch one part of the screen it registers it in a different part of the screen. This only seems to happen when it is plugged in to charge. Also, when plugged in to charge the screen doesn't want to let me unlock it easily. It look like it tries, but only goes a little bit then stops.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Last thought I have, just in case you have not tried it... boot holding volume up AND volume down AND power button at the same time - see if that gets you a response...
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] CarloHD:
Nothing ... I kept it pressed for two minutes, connected to the charger, or even unplugged. I waited 4 hours without touching it, and tried again, turned upside down, shaken, a little abracadabra... Nothing, still dead.
