When phone data is encrypted so twrp can't decrypt it and ask for password.
So We need to find a "fstab" named file in "etc" folder and change its "encrypt" word to "decrypt"
This Fstab file is located inside "System" OR "Vendor folder".
Click to expand...
Click to collapse
For TWRP Recovery Users ( who don't have root)
PHP:
Open recovery mode and tap on "Advance>file manager" and go to this path
For Root Users Use any "Root File Manager".
PHP:
Go to "System/etc" path
OR
PHP:
go to "system_root/system/etc
If Fstab isn't available inside "system" then search it in *vendors* folder
PHP:
go to "vendor/etc"
find ("fstab") named file in etc folder.
maybe more than 1 fstab file will be there.
In that condition.
You need to check which one fstab file has partition blocks names like ("system, vendor, userdata) etc.
so just copy this Fstab file to SD card Or anywhere you like, for editing.
###Editing####
Download"Quick Edit Apk" from store.
Open This fstab file using this Quick edit tool and find line which has word like "data" or "userdata".
Something like these two lines.
PHP:
"dev/block/bootdevice/by-name/userdata"
OR
PHP:
"dev/block/bootdevice/by-name/data"
Something like these above lines.
Click to expand...
Click to collapse
Now Find word similar to "Encrypt" in this line.
Change "encrypt" word to "decrypt" of this userdata line.
You will find one of these like words .
Hint
PHP:
"forceencrypt" >>>>>>>>>>>>>>change it to "forcedecrypt"
PHP:
"encryptable" >>>>>>>>>>>>>>>>>change it to "decryptable"
PHP:
"encrypt" >>>>>>>>>>>>>>>>>>>>change it to "decrypt"
PHP:
"encryption" >>>>>>>>>>>>>>>>>>change it to "decryption"
See I Just Change "en" to "de"
Mean ”En”crypt to ”de”crypt
For example on my phone fstab the line was this.
PHP:
/dev/block/platform/bootdevice/by-name/userdata /data f2fs noatime,nosuid,nodev,discard,noflush_merge wait,check,quota,reservedsize=128M,formattable,resize,forceencrypt=/dev/block/platform/bootdevice/by-name/metadata,
You can see, for me the word was "forcedecrypt".
Click to expand...
Click to collapse
After (by-name) the word was "Userdata" .
Click to expand...
Click to collapse
Now I founded both "userdata" and "forceencrypt" and i changed it according to my need.
("Root Users, You have done eding" Now reset you device and enjoy")
### TWRP Users you can continue ###
go back to recovery and copy this edited fstab to
"it's original location (where you found it).
(For me it was founded in vendor/etc path and i pasted this edited fstab there)
after pasting done, then again go to it's original location (Pasted location)(For me it was vendor/etc)
And tap on this edited "fstab" and select on "chmod" option And set permission to 0644 of this file.
wipe your data, internal storage and dalvik-cable.
Reboot
now error is completely gone
Watch this video of you're still confused.
I think this would cause error, if we ever want to re encrypt the device. Just change forceencrypt to encryptable and perform a factory reset. You will have a unencrypted device with encryption option available.
Please Correct me if I am wrong.
Yes, after your device is decrypted then you can again encrypt it by just changing the word from decrypt>>> to "encrypt" and do a factory reset.
The important part is to find the right "fstab" file from (etc) folder located inside system OR vendor directory's.
And change the encrypt word to decrypt and do a factory reset.
Wrong,
Force-encrypt to decrypt.
Riight
Force-encrypt to force-decrypt.
The number of words should be same after changed.
Like "forceencrypt" (12 words) and i changed it to "forcedecrypt" (12 words).
You just need to change en to de.
Understand.
That's a Common sense.

Wouldn't it be easy just to re-encrypt from setting menu instead of everyone we have to encrypt or decrypt, changing the fstab file. While your way is working, it would be best to make device encrypt-decrypt from setting. Also a plus side we don't need to perform factory reset after we encrypt and decrypt it again.
Cheers!

But Every device doesn't have encryption and decryption option available in settings.
Sometimes this process failed and phone OS said that we need a factor reset.

I have never seen a device without a encryption option.

Yes, true.
But sometimes encryption needs to be disabled to fix 0mb/ unable to mount /data partition error.

After I unlocked the bootloader, I tried to port TWRP from Oukitel k6000 plus since both have same chipset MT6750T and same resolution. I tried to follow this guide on youtube video using Carliv Image Kitchen. But I failed. Heck, I tried to flash the k6000 plus recovery and nothing. Not even boot loops , the stock recovery still shows up.
Edit: I was partially successful. I was able to get to TWRP but touch screen not working. I connected a mouse and was able to change the Russian language of the original k6000+ TWRP port. But what is not working is the mounts of partitions. I tried to copy the mount points from fstab.mt6755 which is in stock recovery to the new port. But the new port doesn't have such file, instead it has goldfish fstab files, I tried editing them manually to match them, but it didn't work.
This is just a stab in the dark. If anyone know how to fix partition mounts and why touch screen not working, I would be grateful.
I replaced recovery.fstab from stock to the ported one also replaced default.prop.
fstab.mt6755 <- That comes with stock recovery

Ulefone Power2 volte is getting enabled.
I am not able to enable volte flag in ulefone power2... Does any one see volte flag as enabled. Even i am not able to root this phone
Please help
Dears,
I installed TWRP on SM-A530F/DS and flashed no-verity-opt-encrypt-6.0 and formatted data to let the phone boot.
Well, I'd like to re-encrypt the phone like I've always been doing on sammys after TWRP or Magisk installation, but it doesn't work on this phone.
No matter if it's Nougat or Oreo, applying encryption nothing happens and phone crashes backing to lock screen in a minute.
Any suggestions?
Thanks everybody.
Id like to encrpt mine too. Twrp and rooted with magisk. when i try and encrpt it just reboots after a minute. SMA530W
Dear @jcadduono,
sorry to bother, I think this issue is caused by Samsung's firmwares but, in your opinion, could it be related to no-dm-verity patch?
Or, is it possible to edit the patch in order to not to disable encryption?
There's a modification (red color in code), I think operated by the patch, to ramdisk's fstab.

Patch operation sounds correct, but this is the only device that fails in encryption them.
Thank you so much.
It's actually not uncommon for a ROM to not be able to re-enable /data encryption from the regular settings, once disabled manually.
As far as I can tell, no-verity-opt-encrypt-6.0.zip replaces the "must encrypt" flag on /data with a "can encrypt if you want" flag. When you format /data from TWRP after flashing that zip, you obtain a non-encrypted partition, but it should be possible to re-encrypt it.
Have you guys tried encrypting data from the adb shell? Details here: http://niki.hammler.net/wiki/Android_Device_Encryption#Setting_up_encryption
This is also recommended reading: https://source.android.com/security/encryption/full-disk
You should also check the system log to see what goes wrong when you try to activate encryption. This is how: https://android.stackexchange.com/questions/26123/android-boot-up-messages-for-debugging
Hello:
I have a Xiaomi Redmi 5A stuck at boot logo. I was able to dump all partitions, including userdata, with miracle box software and test point, but it seems that userdata partition is encrypted.
Bootloader is locked, so I think I can't mount encrypted partition with TWRP whitout wiping data.
I can mount system partition. fstab.qcom content is like this:
/dev/block/bootdevice/by-name/system /system ext4 ro,barrier=1,discard wait,verify
/dev/block/bootdevice/by-name/userdata /data ext4 nosuid,nodev,barrier=1,noauto_da_alloc wait,resize,reservedsize=128M,forceencrypt=footer <-----
/dev/block/bootdevice/by-name/cust /cust ext4 ro,nosuid,nodev,barrier=1 wait,check
/devices/soc/7864900.sdhci/mmc_host* /storage/sdcard1 vfat nosuid,nodev wait,voldmanaged=sdcard1:auto,noemulatedsd,encryptable=footer
/dev/block/bootdevice/by-name/config /frp emmc defaults defaults
/devices/soc/78db000.usb/msm_hsusb_host* auto auto defaults wait,voldmanaged=usbotg:auto,encryptable=footer
/dev/block/bootdevice/by-name/misc /misc emmc defaults defaults
Androrid version is 7.1.2 and MIUI V10.2.1.0.NDFMIXM
I know the pattern.
I have read about some expoits to get MasterKey. Here are some links

I tried bruteforce script included in Santoku Linux and it gives me an error. I passed as header parameter first 2048 bytes of userdata partiton and last 16K as footer parameter.
At footer region, "aes-xts" string can be read.
I am afraid about doing a hard reset, if it will reset / change some kind of random key....
Joke title aside, I had an idea for getting unencrypted and thereby instantly mounting sdcard as internal storage.
The idea is simply going inti the fstab and simply changing the entry for /data into
Code:
/dev/block/mmcblk1p1
. This requires the sdcard to be freshly formatted I think (probably in either ext4 or f2fs)
Going even further, we could get back the internal storage and make it appear as an external sdcard, so it's not totally wasted. (In theory, maybe I'm overlooking something). For now, it's not in the modified fstab.
Only do this if you don't have anything to lose on the phone and on the sdcard
Here's the modified fstab. Would be interesting to see if someone could test it. Copy and paste the text in the spoiler into a new file called fstab.qcom (make sure to save in Linux line breaks if you're on Windows).
Make sure to make a backup of /system/vendor/etc/fstab.qcom before proceeding via adb pull or some other method.
Reboot to TWRP
Again, make sure you have backed up the file you're about to overwrite
Do adb push fstab.qcom /system/vendor/etc/
Reboot
See what happens

# specify MF_CHECK, and must come before any filesystems that do specify MF_CHECK

Looking forward to hearing from someone if it worked and how the performance is.
Good Luck with testing.

Emmc memory is much faster than sd-cards and even more importantly it's much more failproof than the regular consumer grade sd-card. But if low on storage for apps, sure

Wel it wasn't intended to be a serious mod. I'm mostly just curious if it works and need a guinea pig as I can't afford wiping my phone right now ?

Heya guys!
So I've been busy making a TWRP recovery image for my unlocked chinese tablet (a Deejoy q728) that I bought from Amazon. It's a reaaaaally generic one with literally no firmware available over the entirety of the webs(yes I followed every tutorial you could think of that explains how to find firmware, believe me *sigh*).
Now I've gotten TWRP 2.3.6 to actually boot. I used the recovery img from another tablet with almost the same hardware(Concord HS or something) as a base and brought the necessary files into a TWRP 2.6.3 for the AllWinner A23 SoC. with Android Image Kitchen. The steps I took are from this post on DroidWin. It boots but I am encountering the following(major) problems.
1. Even though it displays in landscape, the touch screen seems to think it's in portrait.
2. Partitions just can't be found whatsoever. I think this might have to do with the fact that I don't know too much about fstab.
3. Adbd doesn't work.
By the by, I also edited the fstab files so that they contain the specific partition info of my tablet, not the Concord, as the Concord has several partitions that simply don't exist on mine. Code for twrp.fstab and recovery.fstab down below:
Code:
twrp.fstab:
/boot emmc /dev/block/by-name/boot
/recovery emmc /dev/block/by-name/recovery
/system ext4 /dev/block/by-name/system

# add for recovery
none /sdcard emmc defaults defaults
Edit: The main reason I really want this to end up working is because there are a ton of cheap allwinner a50 tablets and most of them(at least mine) are bootloader unlockable. Add Magisk to these babies and voila! Ya got a cheap device that you can theme to your hearts content. Toying around with tech has always been my thing haha.
So if anyone has any tips for me to get a sorta head start on this, I would really appreciate it!
Sincerely,

I realize this port is now months old, but I did want to ask how your TWRP port worked out? I'm presently working on Allwinner-a50 and Allwinner-100 tablet projects.

Welllll I have no idea how I did it, but I got it to boot. Touch screen drivers functioned overall but while being horizontal, the touch screen responded as if in portrait, so I literally ended up measuring where what button would be on the touch screen compared what was actually displayed. I eventually gave up as something tells me that the A50 might have very proprietary storage drivers, because no matter what I do, twrp refuses to see any device attached. Also, though most allwinner socs are well docd, the a50 isn't as much and afaik the allwinner barely acknowledges the a50. Though I am really happy I got to develop some more experience with things like fstab and it was a lot of fun

Outstanding job. That's no small feat when dealing with Allwinner, and especially their more obscure A-series chipset like the a50. So, TWRP will not recognize USB OTG device or other attached devices?

It won't even recognize the internal storage. When maneuver my why with the barely functional touchscreen to the log option, it just shows a long list of "couldn't mount"s. And no matter what I do TWRP has zero access to internal or external storage. Be it otg or microsd. I've tried several way of formatting the fstabs layout. Be it the average template I would find within twrp, or base my fstabs on those in stock recovery. Anyhow, it was taking alot of time in my life and started to get annoying /hj. Though I am glad I developed some experience. But I wanted to make something that would require alot more time, but would be alot more fun to make. It's a series called "Bull[censored] simulator." Though it's not really a simulator. And the real game lies within. Well... The game itself. As in the hexadecimal, the itchio page's assets and so on. Atm I am busy with a part that inserts it's lore into a Pokémon rom hack I will probably call Bull**** Sim: Pokémon Edition(Working title of course lol) so sorry for abandoning this job. Though I AM glad that people still take interest. Maybe I'll get back to it someday if I ain't beaten to the chase
