Hi everyone,
I just encrypted my android phone (Sony Xperia C4, android 5.0, rooted, unlocked bootloader, Xposed framework on there with the privacy app, titanium backup, TWRP, busybox) with a numerical pin. When it finished encrypting, what appeared is a totally white bright screen that asked me "To start Android, enter your PIN" (not the normal background on my locked screen). :good:
The problem is that there's no keypad.
When I click on the back arrow, the screen flashes for a second but nothing else happens. I tried clicking where the numbers should be, but nothing is typed. When I click on "Emergency call," I see a keypad I can use. I actually was able to type my pin there, copy my pin, go back, and paste it in the gray box, so I've gotten that far, but the problem is that there are literally no buttons that allow me to press "enter" in order to decrypt my phone with that correct pin. If you could please help me find a solution, I would really appreciate it.
Okay, starting to find potential reasons for the error from this thread:
https://android.stackexchange.com/q...rypt-without-system-keyboard-on-android#79050
I did delete the built-in keyboard, which I do not use. I'm posting this here for anyone else in the future, who encounters the same problem. I'm reading through to see if there's a fix or if a factory reset is my only option.
Update: I was able to boot into TWRP. My goal is to see if I can decrypt the phone using TWRP's keypad then flash the stock keypad. I'll update soon.
Another Update: I was following this video (https://www.youtube.com/watch?v=X7yDPszoQ5s) about solving the "Unable to mount /data" problem I was having. Note that in my version of android, only the /data partition is encrypted and not /system or /cache. It was showing up as 0 kb, which makes sense since it's encrypted. Unfortunately, I wasn't focused, so when the poster said to change the file type along with saying "encryption," I absentmindedly followed his instructions and formatted my encrypted data... I know... stupid move, so be warned anyone who is in a similar situation. I then just restored my SD card backup with TWRP, keeping in mind I had backed up my apps and their data with Titanium Backup, too. Yes, I lost some pictures from the past week or so when I did my last backup, but at least I can pretty much get everything else back (contacts, apps, notes, etc.). I'm okay with these little losses as long as I'm learning as I try new things out, which I did accomplish here, albeit by accident.

Hello people. I have a 32 GB Wi-Fi only Tab, running seraphimserapis' CM9 preview kang.
I'll dive right into things here. Earlier today, I flashed the above ROM, everything went perfectly, booted up just fine, and got all my apps back up and running. I was using my tab fine for the entire day with no problems to speak of. Later in the day, I began transferring some misc. files (documents, music, etc) to my internal SD card via MTP USB transfer. After the transfer was complete, I unplugged my tab, and went on my merry way. The next time I booted up, everything began FCing on me, and nearly every app I tried to open immediately FCed. Thinking it was a temporary bug, I rebooted my tab, but the same problem persisted, multiple different processes fced upon boot, and almost all my apps would fc as soon as I opened them. After trying a few more times, I gave up, and booted back into CWM (which I can do perfectly fine), cleared cahce and delvik cache, and did a factory reset. This however,seemed to only augment the problem. Upon booting up (after doing that initial tab setup), trebuchet FCes (in a "FC loop", as it continually tries to open), and the tablet is completely unusable. I have tried wiping cache, reformatting and rebooting several times, each time with the same result
I am able to get into settings however, by plugging in the tab, and clicking USB debugging (for whatever reason, settings does not FC), and am able to connect to my internal memory via MTP. When the tab pops up in my computer, it says I have 25 GB out of 28 available GB, but when I click on the folder, it is completely empty. If i try to move files over to my tab, or even create a new folder, I get an error message saying "the device has stopped responding or has been removed". (Pictures below)

I do not believe this is a problem with the rom for two reasons. (1) no one else has had this problem (to my knowledge), and (2) it was working fine the whole day, until i did that file transfer (that being said, this is my own amateur opinion, which you may choose to completely disregard it in your diagnosis). I am 99% sure I didn't unplug the tab while files were still transferring, but I did not unmount the storage or eject it or anything fancy of that nature before I unplugged it.
My question is, is there any way I can somehow reformat the internal memory of my tab? Otherwise, is there some other possible fix you experts may possibly have? Or am I screwed?
I apologize in advance if you ask me to try something and I cant respond promptly. Its 3AM here and i need to wake up early tomorrow. Thank you in advance
Edit:
I am quite convinced there is some kind of internal memory corruption problem here, but I really am not an expert enough to know for certain. The tablet still boots up fine, but is completely unusable as trebuchet fc loops 90% of the time i reboot the tab. Obviously, the entire thing isnt trashed as it appears to boot and get into the system fine, but I it's still completely unusable from that point on.
I have tried formatting the /data and /cache partitions of the internal memory to no avail. I would try formatting /system, but from my understanding, thats only advisable if you are able to flash a new rom after formatting, but if i cannot write into my internal memory, then there's no way i can flash a new rom. Conveniently enough, I deleted the .zip file for the rom off my internal sd, and i cannot access my clockworkmod recovery from CWM (gives an error, I don't think that would have worked anyway) since the internal sd is (i believe) corrupted. I also tried mounting as USB from CWM, and that also gives an error...
I am clean out of ideas. I'm not sure if this is a completely unfixable problem, or if self repairing is well within the realm of possibility. If someone can shed some light on me that would REALLY be appreciated. Otherwise i might have to send it back to sammy (still under warranty), which i dont mind doing, but if they boot it to find an ICS rom, they probably wont be so keen to repair it...perhaps there's a way to brick it further so they can't tell?
UPDATE 2:
Problem fixed! I still don't have a clue as to what the problem was, but thankfully I managed to escape out of this one. I tried pushing a new ROM via adb, and it worked (apparently), but this just forced me into a boot loop (never hit the homescreen).
As a last ditch effort I pushed the stock ROM, and completely removed root, and it worked. I can now boot up past the spash screen without all all my processes crashing. Really a strange issue, I have my theories, but they're probably blatanly wrong so I'll just keep them to myself. Im just glad I don't have to send it back to sammy... I plan to re-root shortly. I am confident I will get no further issues.
Even though no one helped me directly, it was thanks to the plethora of information available on this forum that I was able to resolve my issue...and for some reason, making a thread where I'm just talking to myself helps a bit too...maybe im just weird. Anyway if anyone's reading this, thanks again xda
.......HOW??

I'm hoping you see this reply as its been quite a while since you've had the issue. I'm working with a Galaxy S2 Skyrocket with the same intenal memory corruption/ files system corruption you were facing. I followed what you did regarding push a rom thru adb and that worked for me, but my question is, how did you get the roms to successfully write if you couldnt write to internal memory? My system is mounted as read only apparently and locked itself with whatever I had on there on August 28th. No matter how many times I format, erase, or wipe it, it returns to the same state as if its a deep lock on it.
Hi everyone
I'm facing a very annoying problem. my Atrix show and explain the problem to me even though I telephonist is all programmatically, they said I need to format but I think I have hardware.
When I turn off my phone every December 6 turns. For example, when I delete one to two applications, photograph shoot, when I reboot the phone by the programs have come back, if my photography is gone, WhatsApp My speech is going back to December 6.Connect the phone to the PC in the same way music, rom, etc. when I threw the zip file .. usb disconnect the look of the phone seems to have deleted files, seems to throw more precisely, I cant go to the factory settings, I cant format sd card.Fastboot mode operations such as hard reset formats'm doing. When he opened successfully but says does not change anything from December 6 phone again Cwm in the mount process data, cache, system, Preinstall, gives an error when formatting. Original GB Stock ROM flashing with RSD, but the phone while flashing process is going repositionable 6 december. Most application itself off, the process terminates, etc.. In short, I can not do any operation with built-in storage, screwing with my head.
Restore backup operation did with cm7 but it did not work .. I'm going crazy I stayed at this rate
ClockworkMod Recovery v5.0.2.0
Checking MD5 sums ...
Erasing boot before restore ...
Restoring boot image ...
Restoring system ...

motorola turkey on the forum topic I said like a friend;
data partition in a way locked there is no problem, linux to interfere with necessary, the easiest services to take, If it fails either of these issues knows linux expert to find, or the phone to open the internal mmc card, remove the atrix in accordance with partitioned, separating reformat back will wear a hardware specialist you need to find. Or one of them will make an application in android professional applications because newly started dating, they needed to find an application that partition control.

That was hard to understand, being a non-native english speaker
Please, after recovery fails to write /data, go to main menu-> advance-> show log. There will be the cause of the error.

I've recently been getting into more security cautious habits with encryption and what not, due to this whole NSA/Big-brother is watching business... But I have a question (more may pop up as this discussion goes on). Sorry if I seem noob-y, I am still getting a hang of all this encryption business. But here's my first round (regarding just the files being backed up):
If I go ahead and do a full phone encryption with my GN2 where will I stand as far as backups to Dropbox/Copy/Google Drive/etc.?
I currently have photos and such backing up to copy, and I often move backups made through recovery to Dropbox and such. If I were to have photos automatically sync to copy or move system backups to dropbox wouldn't that render them basically useless as I am assuming they move out of the phone encrypted (not being decrypted as they exit).
The photos would be unusable anywhere besides my phone right? So moving them off my phone to share vacation photos for instance would be impossible, and if my phone were to crash they'd be irretrievable? Making the backup process pointless.
Wouldn't the back up be rendered useless as well, exactly when I might need said backup? If my phone were to ever crash or die for some reason, I would lose the encryption key, would even be able to do a full system restore through the recovery? It would seem that the encryption key wouldn't be kept with those back up files, so while it might place everything back in its correct place, it would still be unreadable. Or does it maybe keep the key in system files somewhere so that a full backup would restore the key as well?
And my second round of questions (regarding recoveries and what not):
I am also under the impression that I would not be able to flash through custom recovery either as the internal SD would be inaccessible from the recovery being it doesn't have the encryption key. I am currently running OmniROM and it is in a nightly stage still for my phone. I wouldn't be able to update nightly would I? I am assuming since it basically flashes/overwrites system each time, that I would be losing my encryption key and making everything besides system unusable then right?
And what about downloading ROMs to flash/update directly to my phone? As I download them from in browser or another app and they go to the default /downloads folder they would be encrypted. They wouldn't be accessible from there in recovery, but if I were to try and move them out of internal SD to the external SD they would retain encryption and still be inaccessible? So the only way to download ROMs and updates would be from PC and only move them to the external SD?
Overall, this seems to be crippling a lot of the way I use my phone...
Bump?
Sorry, this is already getting buried and I kinda want to know what's going on before I go ahead and do this...

I'm not (yet) an expert on this, but when you've encrypted your device, it encrypts the file system on your internal memory and SD card. You have to enter a PIN/password when you turn on your device (and when it times out) to gain access. When the correct PIN is entered at boot time, the file system is available as normal - the underlying data is still encrypted, but the file system can unencrypt it in "real time" for use by apps and the system.
So that means that Dropbox et al all see your files as normal, and any copying you do from your device to something on the net (Drive, Dropbox, a server, etc.) works as normal - the data appears normal to the apps and is copied as normal. So photos would copy across as photos, music as music, etc.
Think of it like this: You can't speak Urdu, only English. There is a book you own that is written in Urdu that you want to tell someone about. You find a translator to read the book and tell you what it says. He reads the first page in Urdu, translates it in his head to English, and tells you what it says. You then tell your friend what it says (in English, of course). Your friend writes down what you told him, in English, then tells you something in reply. You tell your Urdu translator what your friend said (again, in English). Your Urdu translator then translates (in his head) what you said from English to Urdu, and writes it down in the book in Urdu.
At no time do you understand Urdu, nor does your friend. Your friend doesn't even know the book is written in Urdu and doesn't care. He never sees it or accesses it directly. If anyone ever steals your book, they can't read it unless they can read Urdu. The book is only useful to you and your friends if you have an Urdu translator sitting there in the loop. (the analogy is imperfect and incomplete but you get the idea).
So, getting back to your phone, if you have it encrypted, the underlying file system deals with translating things on the fly if you've given it the correct password at boot and login time. No apps ever know about the encryption - they just see data as normal (unencrypted). So any app that wants to copy a photo to Dropbox just sees a normal photo - it never sees the underlying encrypted data. But if you don't enter the correct password at boot time, the phone can't boot, and anyone trying to access the data on the phone won't be able to read it unless they know the password.
Does that help or confuse?

Hmm, this does my head in a bit but lets untangle it:
- you boot into Recovery. The Recovery you're using (obviously) understands encrypted file systems (some versions of CWM do, some versions of TWRM don't for instance - see near the end of this post for a bit more on this). So when you boot into Recovery and enter your PIN/password, it can then read your file system. You can then do a Recovery-based backup of your file system (or individual files, though I'm not aware that you can do this). The backup it creates is written to the encrypted file system and thus encrypted with the same encryption keys used for everything else.
- You boot the phone back up as normal and enter your PIN/password, and start up Android. You then use Dropbox to copy the Recovery backup files to the cloud. So the question is, "Are these files encrypted?" and I think the answer is, "No". Why? Read the rest of this post and hopefully you'll work out the same conclusion. But I'm pretty sure that the data that ends up on the Cloud is not encrypted.
One general comment worth pointing out as an aside (sorry, this paragraph isn't really related to the above but I wanted to point this out somewhere and its still useful) is that each time you encrypt your phone, it creates a unique encryption key - even if you give it the same PIN/password to use. So if you're forced to rebuild/reflash/wipe your phone in the future, it won't be able to access any data that is still on there (in internal or SD memory) since it won't know the previous encryption key. So you'll have to wipe all data and start again. And at that point, if you choose to encrypt your fresh, newly initialized phone, it will have a new, unique encryption key that won't work on any encrypted data from previous. So if for instance, you plug in an SD card that was encrypted on your phone in an earlier ROM, it won't be readable even if you know the correct PIN/password, since your phone will be using a different underlying unique key.

So, if you're following this, you'll now understand that moving your photos off your phone could be done two ways:
- while you're using the phone as normal (ie. you've booted it, entered your PIN/password, and copying your photos to Dropbox via an app while you're logged on. If you do it this way, you're simply copying photos as normal that can be viewed as normal in Dropbox.
- by copying backups generated while in Recovery. But Recovery will be firstly mounting the encrypted file system successfully (if you gave it the right PIN/password and your version of Recovery supports encryption), which means it can read your photos as normal files, then backs them up into its own normal Recovery file/folder structure and writes them to your encrypted file system, so the underlying data is encrypted unbeknownst to Recovery. Then when you boot up your phone and log in successfully to Android, you can access that data as normal (and unencrypted). So when you then copy it to Dropbox, all you're copying is normal Recovery-created backup files. The copied data won't be encrypted (unless Recovery encrypts them itself, independently, which I don't think it does). So you could copy this data to anybody's phone, so long as they were using a compatible Recovery version and probably compatible ROM.

I'm not 100% sure on this, but I think your logic is correct. The backup would be useless if the phone loses the encryption key, which it would do if you re-initialized your phone and/or did a new encryption. So you can only recover your backed up data if you haven't done either of those things. A solution to this is to use backup software that runs on your phone (Titanium Backup) that gives you the option to encrypt your data. Some caveats to this approach should be obvious:
- you firstly need to decide if you trust your backup software's encryption
- you need to use a strong password and be able to recall it months/years from now when you go to restore your data
- you need to copy your backups off your phone (such as onto your SD card, cloud, dropbox, etc.) in case you lose your phone.

I am also under the impression that I would not be able to flash through custom recovery either as the internal SD would be inaccessible from the recovery being it doesn't have the encryption key.

Tricky - if you flash/update your phone with a new ROM, you will probably be OK so long as you haven't wiped the part of your phone's storage that holds the encryption information. I don't know where this is. But the nightly updates I do to my phone don't normally touch my data - all my apps are still there and it boots identically to the way it did before I updated it. HOWEVER, its possible that an update may force me to wipe my phone for some reason - the update may fail, it may contain significant changes, or I might screw something up. I probably end up completely wiping my phone at least once every 2 months just because I like to play with the latest and greatest ROMs, or I screw something up. So if that happens, I'm going to lose the encryption information and thus would lose everything on the phone.
Of course, I can always restore my apps and data via Titanium Backup, since I back up my stuff quite often and then copy it to Dropbox.

Hmmm - good question. A simpler question is, "Is my encrypted file system accessible while in Recovery?" I believe the answer is, "Yes, if you use CWM, No if you use TWRM". But I say that because from what I've been reading, some versions of CWM/TWRM can/can't handle encrypted devices. But you'll already have sorted this out at the time you're trying to encrypt your device anyway since the encryption process involves rebooting your phone into recovery I believe - and if you're not using the correct supported Recovery, this step will fail. But if you are using a supported recovery, this step will work, and therefore logically I'd assume that you can access your encrypted file system while in Recovery in the future. I'd imagine Recovery would prompt you for your PIN/password in order to mount the encrypted file system.
So assuming the above is correct, you would be able to access the newly-downloaded ROMs while in Recovery and thus can flash them. But of course, Caveat Emptor with flashing the new ROM - if it forces you to wipe anything, you may end up unable to access any of the data.

From what I've been researching, you won't have a problem anyway, because I haven't come across anyone that has successfully encrypted their phone using a custom ROM. Strangely, this ability seems to be unwanted by XDA people. My tinfoil hat tells me that there are people ensuring that this ability continues to not work on custom ROMs until/unless a backdoor capability is found. Hopefully I'm wrong on many counts.

Amazing post by the way! It does seem very helpful.
BUT it's very funny you mention it not working. Because that's exactly what happened. After not getting a response here or in the ROM's forum for a few days, I decided to just take the plunge and do it. I was just planning on testing everything out my self and figuring it out as I went. The first time it seemed fine, the encryption went through it seemed.
Being as I didn't know any of the info you just enlightened me with, I did fear that nothing was truly encrypted though. Everything was transferring to my computer with a drag and drop and working fine, so I was afraid (without evidence) that nothing was truly encrypted. I asked on the ROM's forum again (still waiting for an answer).
That night, my phone was left plugged in charging, yet some how had turned off in the night. I awake to my phone asking for an encryption key. I enter my key in to no avail. Nothing works and my phone is left unable to boot. It was utterly denying my password. I had to reflash. I asked about that in the forums as well, whether that was normal or if encryption was maybe not implemented yet, etc. The dev running the nightlies for my device has responded to the forum multiple times but not to me. Another user mentioned it might be that it is now merged together as a Galaxy Note 2 ROM and not specifically a T-mobile Galaxy Note 2 ROM (might be possible. Idk.).
Now, I have tried to re-encrypt. Multiple times. But I cannot for the life of me get it to even start now. Every time I go to start the encryption process it shows me the fullscreen image of the android unzipped horizontally (at which point it is supposed to reboot and start encrypting) and it hangs/sits there forever. Not rebooting, not anything. If I hit the back button, the image disappears and it goes back to my phone. Working perfectly fine, like it never even started doing anything. I am not doing anything differently. I don't know what could be happening to stop it from even getting as far as it did last time. Unless the devs maybe started working on it and have disabled it for the time being/screwed it up worse, I dunno.
Not you got me crafting a tin-foil hat...
Hello everyone,
I need your help. Sorry for the long post.
I have a OnePlus One. It was running on CM 13.0 (Android 6.0.1). I had TWRP and MultiROM installed.
I have had an issue where whenever I flash a zip file in TWRP, the phone will show an error after installing the zip: "Unable to mount storage". This appeared in red color on the screen right after showing the progress of the zip installation. The phone worked fine and all the flashed zips worked great as well. However, the error that appeared every single time when I flash a zip file bothered me. So I tried to fix it. (I know, if it's not broken don't fix it, but sadly I tired).
I followed this video to get rid of the error => (https://www.youtube.com/watch?v=X7yDPszoQ5s). However, instead of getting rid of the error, I ended up with a huge problem. My phone couldn't recognize the data in the internal storage. It showed that the internal storage was empty. When I tired to reboot in TWRP, It said: "No OS installed are you sure you wish to reboot". I realized that the video I followed was for a different problem and that I ended up with the same issue the video was trying to fix! I tried every single option the video suggested to fix the problem and nothing helped.
I connected my phone to my laptop and downloaded the latest CyanogenMod zip for my phone and I flashed it. when I rebooted my phone I got a screen that asked for my password. I typed a random password (I discovered later that the phone will accept any password and say it's correct). I got the following error: "Decryption Unsuccessful... The password you entered is correct, but unfortunately your data is corrupt... To resume using your phone, you need to perform a factory reset. When you set up your phone after the reset, you'll have an opportunity to restore any data that was backed up to your google account...Then the only thing I can select is "reset phone." ". I pressed the reset button on the screen, the phone rebooted and showed the same error. Then I tired flashing PAC ROM and I got the same error again. Then I flashed OmniROM and the phone worked! It didn't show the error.
I have a Titanium backup for all my apps and I also have a nandroid backup for my previous ROM (in my memory stick using an OTG cable). However, I don't have any backups for my internal storage (photos, videos, documents... etc). I am guessing that these files are still in my internal storage. I didn't copy any new files to my phone because I think if I do, then the phone will keep replacing my old files (that I can't see) with the new ones.
My question is: Is there a way to get back these old photos and videos from the internal storage? Note that I didn't delete these files, but the phone can't read them. Also, I checked the nandroid backup that I have and the file system type of the previous ROM was EXT4. My current file system type is the same, EXT4.
Thank you for the help!
Hi All,
I have LineageOS running on a GS5 (G900I) and while it runs beautifully, every 1-2 weeks I have a hang that I cannot recover from - Even after reboot the phone hangs immediately - I can swipe across screens in Trebuchet but no widgets will run and the phone will hang if I try to open any app.
The *only* way I have been able to recover is to perform a restore of my /data partition from a TWRP backup. I've tried wiping cache, dalvik-cache and restoring the /system partition, but this does not help. I've upgraded LineageOS a couple of times to the latest. Now I seem to have to make a backup of /data every day or two, as I never know when this problem will strike again.
My /data partition is encrypted. Filesystem is ext4.
So I have really 2 questions:
1. Can anyone suggest the cause? I can't find any mention of this as a common issue.
2. How can I troubleshoot this? I can use "adb" when booted into TWRP recovery but it seems I cannot use this when the phone is booted without enabling USB Debugging in settings first - but when the hang has happened I cannot launch Settings to enable USB Debugging, so there appears to be no way to see any logs.
Any help would be appreciated...!
