Blackview BV9900 restoring backuped partitions problem - Android Q&A, Help & Troubleshooting

Hi
I woud like to restore partitions blackview bv9900 (Android 9.0 Pie), which were read back by SP Flash Tool. After restoring during booting after logo blackview i have announcement "decryption unsuccesfull, your password is correct but data are corrupted". Propably it don't works for encrypted data partition. I tried to disable dn-verity on vbmeta.img again but did't help. I can only reset to factory settings and install everything again. Images was made after unlocking screen PIN code. Maby someqone here know a solution?

Wipe / format Android's partitition in question, which removes encryption and ensures the related data stored therein is deleted as well, before restoring.

Sorry I can't be of help, but that's not a Galaxy S3 so I'd refrain from attempting to flash any more ROMs from this forum section...

Backing up wifi passwords without root(restoring backup after unlocked bootloader)

I have a One V, and I want to backup atleast 30 wifi passwords I have stored on my device, but all the apps on play store require root.I can't do that as unlocking the bootloader will remove my phone data, so I'm asking :
If I unlock the bootloader and then restore data still with the stock ROM on, will it restore the wifi data automatically, and then hopefully I can back it up with a wifi backup app (cause there is no way to root device without unlocking the bootloader atm)?Here's what dashboard is showing as backed up:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Anyone?
Even I'm looking for such a thing... No way I guess!
No there is no way. Also restoring that data is known to cause issues.
Phones in which rooting is possible without unlocking the bootloader is the only way!

I tried to wipe cache/dalvik-cache but it always failed. Im using stock mui 11.0.8 android 10. after i unlock my bootloader, flashed TWRP, then Flashed DFE and last magisk..then i want to try kernel but i cant wipe my cache/dalvik-cache. I think its encrypted but why? I already did flash DFE?
try this
1. poweroff for a while and boot in to recovery and try wiping
2. use pitchblack recovery as your handler https://sourceforge.net/projects/pitchblack-twrp/files/beryllium/
3. also you can try https://forum.xda-developers.com/poco-f1/development/recovery-twrp-3-3-1-beta01-touch-t3987567
i am using pitchblack and i am happy about it
if you know the encryption thing, flashing DFE is recomended but it will make your device unsafe to another level, encryption will be gone so anyone who can get hold your device can actually retrieve your data through recovery!
however if you don't flash DFE, you may loose your data because every flashing will reset the vendor keys and internalstorage will be formated

s7 samsung link2sd loose link to second partition

hi i have a strange problema with the app Link2sd
i have my phone rooted with android 10 floyd rom. i use a galaxy samsung s7. if i move the app to the sd the app just works fine. but if i use the second partition and i reboot the phone i lose the app linked to this partition. it's very strange because usually the app dont lose the link to the second partition. if a try to recreate the script i have an error message.
the oly way to recreate the link is to click on " recreate link to the partition " several times then always with the error i do the fast reboot and then i have the link. but i lose the app.
is there a way to link to the second partition and don't lose this link at the reboot ?
thanks for the help.
ps: i've tried the method to make links2SD a system app with titanium backup or manually but does not work
