When I try to mount the encrypted internal memory partition in TWRP, it says password failed with every attempt. I have tried patterns, pins, passwords, default_password, but there is probably a bug. Does anybody know a fix?
I need this, I presume, to flash the Xposed installer zip. Or is it possible to flash this withouth mounting the encrypted memory?

Hey guys,
My work switched to Google Apps for their email so i wanted to test it out on my phone. Doing so required them to encrypt my phone. What this appears to have done is encrypt the data partition. So now when i go into (TWRP) recovery and try to do a backup / wipe / or anything else, it says it is "Unable to mount /sdcard" I'm unable to do a factory reset of any kind so i'm essentially stuck on this rom (ARHD) until i can figure out how to wipe data and get the /sdcard to be not encrypted. Does anyone have any ideas? I'm imagining that with the modified recovery not being able to access the data partition that i'm going to have to do some adb type stuff?
Please help! I want to keep flashing new roms!
Anyone??
I think you can't decrypt your data partition...
Did you try to wipe your data partition with the latest TWRP?

That's the thing, the recovery can't mount /sdcard so wiping isn't an option from recovery

Hi! Only TWRP recovery can solve your issue just do this...
Boot to TWRP recovery->Wipe
From there there are 2 options the left is the advance wipe and on the right is Format Data
Just select the format data button and it should reformat the whole data partition.
1st one would prompt so many errors and reformat then reformat it again 1 time and it should fully reformat your phone.
In theory it should reformat data partition even when encrypted but just in case it fails and I won't be able to go back to this thread just boot in bootloader and type
"fastboot erase userdata"
Well none of that works. TWRP doesn't support decryption yet for this device.

What I instructed basically doesn't decrypt the partition. It reformats it.

I know what you instructed, it doesn't work. Only way I got it to work. Flash the stock recovery. Boot into system. Take off the encryption, phone reboots and removes the encryption, data is formatted. Then flash TWRP again.
I basically ran into this exact problem. I was hoping that I'd still be able to back up the encrypted device, but forget about it. What a pain in the ass.
Someone should make add something to the guides about how encrypting your device makes nandroid backups impossible.
I am thinking of encrypting my HD+ (Settings>Security>Encrypt Tablet). As far as I can see this means simply that the /data partition will be encrypted and that CWM is afterwards not able to access this anymore (ie for backups or restores). I can do a complete backup by other means, but how would I be able to restore that?
Will the recovery still boot and will I then be able to format/wipe /data? Probably not because /data is not mounted!?
Also, what happens if I want to update the system, say to a newer version of CM?
So no one's ever tried to encrypt their HD/HD+?
I am still investigating this "problem" and it seems that quite a few people have run into trouble after encrypting their tablet (TWRP Recovery seems to support an encrypted /data partition but CWM doesn't... correct me if I'm wrong).
So here's a question for the Linux gurus: if I have booted an encrypted tablet and have opened a terminal window with full root access, will I be able to unmount and reformat the /data partition? After that I should be able to reboot into recovery and restore a backup.
I have a new LG Optimus L90 (D415) with stock 4.4 ROM, and TWRP 2.8.0.0 (and previously, Philz 6.58.7) for recovery. Obviously, the phone is rooted and now has an unlocked bootloader....
My problem is that neither recovery will back up (or even mount) "/data". Note that I put that in quotes because, without having "/storage/sdcard" or something in front of it, I presume that it's an internal folder and not something to do with the external SDcard.
My first guess would be a problem with encryption, because both the phone and the external SD are using it -- and I never get asked for the password. Either way, the actual error in TWRP says "E: Unable to mount 'data'", while Philz says it can't access /data/philz-touch for the .ini file.
I've made several Google expeditions to find the answer, and have come up empty-handed with all of them. I've seen all kinds of fixes, from claims that I have to run chkdsk against the SDcard, to backing up the entire /data partition with a tar file and reformatting it with command line nightmares.
I'll do what I have to in order to fix this, but I'd rather not embark on an experimental goose chase. Any ideas?
I have this same problem. But only for wiping and flashing.
I have no idea for fix if backup also not working !! (Noob)
1.TWRP click backup. Select all except SDcard.
Finish backup.
2.go to Wipe menu.>advanced wipe>select all except System and Sdcard.
Wipe.
(It will skip the error files)
3.Install menu. Select ROM to flash.
Was what I did.

I'm not flashing anything, yet. First I need to make a backup of the entire phone (not including the SDcard). That way, if something goes wrong, I can just restore my old, working configuration -- all at once -- and start over.
I can back up and restore apps individually, using Titanium Backup. But what I need here is a Nandroid-type backup... and that generally has to be done from the recovery partition. There is one other way to backup everything, using a laptop/PC and ADB. But I've never tried it, and it wouldn't protect against a ROM meltdown.
Solved, somewhat...
So I did some further experimentation concerning this error. I did a test run to install CyanogenMod, and I found that I couldn't even factory reset certain partitions because of these "Unable to mount /data/" type errors.
What was ultimately the problem? The encryption. Once I decrypted everything, TWRP was able to see, mount, and backup, those partitions.
But I was under the impression that TWRP handles encryption, e.g. asking for the password, or some such. I mean, how can you do a Nandroid-type backup on a phone, if no recovery can mount those kinds of partitions?
So, for the record: "E:Unable to mount" was definitely due to the encryption being turned on for my internal storage. Thus the solution (so far) is to decrypt storage. A wretched solution, but at least it works for the time being.
BTW, In furtherance of this research, I formatted my internal SDcard to NTFS, just to make sure it wasn't misaligned or whatever when it was just FAT32. And I discovered that NTFS takes forever to format (32GB on the order of a couple hours)., FWIW.
The plot thickens. It may not be sufficient just to undo encryption, there may be something wrong with the way that partition was created, or otherwise is constructed.
Even though I now am able to mount /data, I'm not able to format it.... in TWRP it says something like "unknown filesystem 'auto'".
But there is a thread here that describes using Philz recovery to unmount and then format this mess, and I'm about to try it, I just have to flash Philz in place of TWRP. Now let's hope this version works without issues, because I'd have little recourse if things go bad there.
Hello and greetings from germany,
I have a problem with my Moto G 2014 XT1068. I'm coming from rooted stock KitKat (Xposed) with open bootloader and TWRP 2.8.6.0. Everything seemed fine until yesterday, when the phone just went off (0% battery) and stayed at boot animation.
I've tried a lot of things, but the phone seems to be hardbricked:
- I can access recovery, but restoring does "FAIL" (restoring boot partition works, though). Restoring "system" aborts at about 18%, "data" immediately.
- I can access the phone through fastboot, but cannot flash anything. Whatever I do, the phone isn't changed. Tried reverting to stock (getting error when flashing gpt.bin, everything else seemed to work without errors, but no changes), tested flashing other recoveries (partition size mismatch, but that seems to be normal, whatever I flash, it keeps being TWRP 2.8.6.0), or even upgrade the bootloader (no errors reported at all, but no changes made to the phone).
- I can access the phone by MTP from TWRP, but cannot write to or delete anything from the internal SD.
Do you have any further ideas or is it an hardbrick?
Thanks in advance
René
Seems like the internal SD card is damaged, or there's a faulty partition table. Have you tried repairing and formatting /system and /data partitions with TWRP? Does it read external sd cards? If yes you could try flashing CM11 (because lollipop roms need an updated bootloader) from an external sdcard and see what happens. Also your backup could be corrupted, that's why it doesn't let you restore it at all.
As for the recovery, try updating your twrp to the latest version available (3.0). You can update twrp from twrp itself, just to see if it's fastboot's fault.
Wiped /system and /data. Didn't help. Wiping /data/media led to an error.
Is there anything beyond "wipe" to repair and format those partitions?
Thanks for the hints, will try updating TWRP and installing 11 this weekend, as external SDs can be accessed.

Hello everybody,
I flashed some rom from other forum which changed my vendor(i guess by twrp messages) and I forgot to flash disable force encryption zip, so now i have encrypted storage, no system and some different vendor which wasn't on my device by default. I have access on twrp and fastboot and all but how can I install system on encrypted device without losing my data(factory reset to decrypt storage) phone?
Edit: by data I mean internal storage not app and rom data. I already wiped them.
copy data to pc or in pendrive using otg then proceed
