flashed portet TWRP recovery, no sd card
04-11-2021, 11:10 AM
System: Android 10
Chipset: MT6779
System is rooted and DM verity is disabled
recovery.img is succesfully ported with V1.8a Gui
TWRP works
/data is set to encryptable in the fstab.mt6779
SD Card is fresh formatted
TWRP shows SD Card with (0) - and is not mountable
In the Android System the SD Card works.
How can i fix this?

My fstab.mt6779 files has following for the extrenal storage:
/devices/platform/externdevice* auto auto defaults voldmanaged=sdcard1:auto,encryptable=userdata
/devices/platform/11200000.usb3_xhci* auto vfat defaults voldmanaged=usbotg:auto
the default /patch/10/ramdisk/init.rc from porter shows
export EXTERNAL_STORAGE /sdcard
I dont play arround with these files to find out what could help to get the sd card working in TWRP.
Just following this advice "Warning: It might brick your phone! " : https://www.hovatek.com/forum/thread-102...l#pid60316

Are you able to mount other partitions and (access) internal storage too?

I was able to port a working TWRP recovery image from my Stockrom recovery.img. Now not anymore and i have no idea why. it was working, now not. I tested it on three different machines, without success. The output size of the ported image should be the same like the input. Its not.
If i reboot to the recovery mode, the device tries and ends up after a second reboot back in the bootloader.
Then i can recover the working TWRP i did by accident, and it works again after a reboot....without sd_cad... so its useless.

If you ported with our tool the first time then nothing should've changed unless there's a variable you introduced and have forgotten.
If the only problem is SD card not mounting then have you tried a different SD card? Also, provide a link to the working TWRP

The Gui tool itself gives me not many options, "check image" and 3 different OS where i chose only Android 10 of course.
I took the exact same stock rom image "BV9900Pro_EEA_S900AA_V1.0_20201105V07_user_20201105"
Log Output:
"... start log ...
Recovery image isn't signed
Recovery image unpacked successfully
All port files copied successfully
Recovery packed and copied to output folder successfully
... end log ..."
"If the only problem is SD card not mounting then have you tried a different SD card?"
I didnt tried another SD Card, it works on the android system, its a 32GB small one. As soon i get a OTG Adatpter i hope this works.
"Also, provide a link to the working TWRP"
See here, its all there - https://www.hovatek.com/forum/thread-218...#pid221060
and here again the link to a working TWRP for MT6779 - but with default recovery.fstab from porter 1.8a- https://www55.zippyshare.com/v/y335SXUU/file.html

seems, i am not alone with this trouble. it is such a nice device but it lacks in support.
Miracle Box 2.82 is to old for this Device, MT6779 is supported from 3.21 and newer. (pay to play)
Exact same is with the WWR 2.51 Tool. There is no further release which supports newer devices.
Titanium Backup does not save well the system settings, it lacks also with some chat apps like signal.
SP_flash tool does also not work after a full backup/restore procedure, the system is in factory reset mode later, datas / settings lost, no matter if its unencrypted.
So this is the complete list what i tried, any further suggestions how i can backup a working custom stock rom?

Yes of course, are you kidding me? it is the only reason why i am doing this, using TWRP. i found no other solution doing a full backup of my device, without later adjusting lots of system settings, re-installing apps, re-configuring accounts and so on. it is only for personal use, backing up my device., I do this for 30 years with my PC´s, called imaging, started with Ghost, did it with my older mobile models for 10 years and wanna do the same also with my new phone, the MT6779. Any suggestions?
Ps. the OTG test nearly bricked my device, i tried from TWRP accesing the OTG, listed with (0) but the Hardware was not rly activated. I didn't knew this at that time, so i tried formatting the USB Stick and found out, it was the local boot Partition (32MB) which i formatted. The good news, with sp_tools i was able to reanimate the dead Blackview. i am rly close to sell this device and buy a 7 year old model because this sh* makes me nuts.
