So, I have read a lot about TWRP sometimes bugging out and randomly encrypting phones and adding a password to which the user either never set it up or that TWRP doesn't accept it. This has recently happened to me and I cannot use my phone and I don't know what to do.
I have had the bootloader of my phone unlocked since day 1 when I bought my phone (release date last year) and have been running PA ever since. I have never had any problems with it, until about 5 days ago, when I grabbed my phone and everything started crashing and the camera was apparently not available. I didn't know what was the deal with it, so I rebooted the phone and it entered a bootloop (it hangs on the Google logo for about 5 minutes and then it hangs on the PA logo screen forever). I went on to the bootloader and started TWRP to see what was the deal. I originally wanted to grab certain files off the phone in case I had to do a system format, but when I got to TWRP, it asked me for a password which I have never set up and I tried every combination I could think of but it always failed. Everything was encrypted and without the password I couldn't get to it. I tried wiping everything including a factory reset before resorting to a system format (which I read about it and apparently is meant to be the solution). Everything failed because it couldn't access the /cache, /data, nothing. I went on to do a system format and although that is meant to wipe the phone and remove encryptions, it also failed to wipe the /cache and although TWRP says that the wipe is successful, the phone is still encrypted, the password is still around and it bootloops. I have tried the system format like 50 times and always the same.
Can anyone help me out with this? I am currently travelling around but am at a hostel where there is great internet and pcs, so I can install drivers, toolkits and such. I actually started looking around for new phones, since I cannot for the life of me get the phone to start again.
Note: The phone was working perfectly fine, I put it down to have dinner and once I finished, I tried to use it and it started to bug out. I also read around about this, and everyone's issue gets fixed after a system format.
Any help, would be greatly appreciated, that phone is the only net device I have on this trip and it sucks to not have any way to contact anyone.
Thanks.

Don't blame TWRP for something it doesn't do.
Looks like your device have an EMMC failure, sorry.
You can try installing factory image, or last resort restoring by download mode, but I think the flash memory in your phone is gone.

I didn't mean to blame TWRP. It is just that it was when I am on it that I get asked for the password and I was under the impression that it was TWRP that did the encrypting (I am in no way a developer or even very knowledgeable when it comes to the under the hood stuff, I usually only follow the tutorials). But thanks for the reply and the link, I will try that and hopefully get the phone back working.
Also, I did read in a thread that apparently this can occur due to hardware failure, I was just hoping this wasn't the case.
This happened to me on an old phone. Not sure why. Factory image fixed it. Could be a different issue but its worth a shot.

Did it suddenly happen or did you change ROMs?
I tried a new rom for the first time and then went back to wicked 9.1, I'm thinking that triggered something.
I think I got a fix though, look here: http://forum.xda-developers.com/showthread.php?t=2588377

Got my S4 4 days ago sprint 4.2.2 MF9 and rooted using odin 1.85, CF-Autoroot by chainfire (CF-Auto-Root-jfltespr-jfltespr-sphl720), CWM flash, then MF9 Odexed hotspot mod (MD5: b1f54ecf82719255ff39eb88d0095ccd). All went well with no error's or issue's, so I did same on 2nd new S4 - same 4.2.2 MF9 for my wife. Made CWM images of both on SD cards. Installed link2sd and foldermount, did nothing else but move movable apk's to SD with link to SD, never used foldermount (yet).
4 day's later my phone froze while texting and re-booted, froze while making a phone call 5 minutes later and re-booted (by itself). After about 6 re-boots it failed to boot and went into a boot loop, making it to the Sprint screen at first and then only to the Samsung logo screen upon subsequent re-boots. Removed battery after the 2nd re-boot (early on), and tried leaving it out for 10 minutes and then half an hour after 6 or 7 re-boot's - no change. Tried restoring from CWM image, showed success but same boot loop. Even tried image from other S4, same results.
Read as many posts as I could, and after study re-flashed stock recovery and stock firmware. Phone still will not boot, but is stuck in boot loop, now with stock recoevry. Other phone with same done to it, same programs (apk's), all exaclty the same is fine. Is it possible that the phone has a hardware problem?! Since I rooted I have 'Custom' now in Download mode so am afraid to take it back for replacement and can't get to boot so triangle away is not possible. Any suggestions, or have I just lost?! Need a phone for work, so don't have much time to play with it, have tried for 2 days now to remedy - but very...well upset :crying: Any thoughts or suggestions?! Thank you!

Go into stock recovery and hit wipe/factory reset and see if boots up after.

If doesn't work I suggest to try the one click mf9. You can find it on development section and do a factory reset after. Also that should bring Odin status to normal. It did for me.

Yes, I neglected to include that I tried wiping cache first, then re-boot attempt, then cleared cache and factory reset, then tried to boot, then wiped cache and factory reset followed by CWM recovery then boot attempt, then cleared cache, re-boot attempt, then all over again and flashed stock - all with no change - boot loop prevailed. What troubles me is that with no other changes the phone froze and re-booted on stock firmware?? And weirder still that once it re-booted the first time it stayed alive for 5 minutes, then 2 minutes, then less than 1, to 'that's all folks' and continued to decrease how far it even went in boot attempt. To the 'slightly informed' like me that seems strange - that's why I was wondering if it could be a hardware failure causing ROM or RAM to be corrupted further with each boot attempt - or - with time 'on'.??
Will try one click mf9 and post back

I had not tried that - put myself under the assumption that is was the same as what I had done 'manually' with oden so didn't also try that. With your suggestion I will however - what have I got to loose at this point?! Will post back with results - have to wait until later, meetings call
Downloading it from rwilco12 in the meantime, both rooted no data restore and stock factory restore versions. I will obviously try the stock factory version first as I have wiped already and have no data to loose.

This is why when you get new phones always test them out on their full capacity for a week or so. So that you know you dont have a defective device.

I am actually sure it was on 4.2.2 the day it died - still had the notification nag that update was downloaded. I was going to look for how to remove that 'nagging' notification but hadn't yet. Since I rooted the day I got it and installed CWM any OTA update (4.3) should have failed even 'if' I accidently hit the 'system update downloaded' prompt on my notifications screen, which I didn't. The phone had been on for about 4 hours when it first locked and re-booted while texting - and had it updated it would have had to re-boot which I think I would have heard/seen/witnessed some kind of evidence that it had. I think you are going in a good direction though, looking at all possibilities. I know from root checker it rooted successfully and since I made a CWM backup I know stock recovery was gone - so very unlikely 4.3 found it's way in.
Have you tried to boot without the micro SD card installed? The card might have corrupted after you used foldermount and now the phone would t boot.

No, I only installed but never opened or set up folder mount so that never even crossed my mind. I just got home and have a few things to try - and I think the first and simplest is removing the SD card! OK, tried that to no avail - boot loop get's to samsung logo and repeats. Tried to clear cache and factory reset with card removed and tried again after battery removal for 2 minutes. Same situation - nothing has changed. Will try 1 step restore next. Downloaded on my laptop but had to leave that with a co-worker for data aquisition project - have to download again here at home.
This is off track, but I have never asked for help and//or participated in a forum like this before. I am happily suprised by the intelligent, thoughtful responses I have recieved so far. Didn't expect anything, but am glad I asked - and even though I am still 'stuck' I have had incredibly good input into potential resolutions for this issue. Thank you all for the assistance so far
The best thing for you to do at this point is to odin a full tar and do a factory reset. To make sure you load the correct one we need to confirm your version. Enter download mode by holding volume down and power. Once it loads, select volume up to enter download mode. The should be a bunch of text lines in the upper left. Look for a line that says knox warranty. If you have that line you are on the mja update. If you don't have that line than you are on mf9. Goto sammobile.com and download the full mf9 tar file through odin and it should return you to full stock unrooted. You may need to do a factory reset in the stock recovery if it doesn't boot all the way. If you do have the knox warranty line than your phone updated to MJA and you need to install that tar instead. Good luck.

Didn't know that line would appear on MJA, but as suspected that line is not in download mode screen's top left verbiage so that gives me confirmation that device didn't sneek from mf9 to MJA.
Late last night I tried both rooted no data restore and stock factory restore 1 click versions from rwilco12. Both appeared to go without a hitch and still after flash and clear cache and factory reset neither allowed the phone to go past the Samsung logo screen. I even tried removing the battery and replaced with that from my wife's S4 to rule out any weird voltage induced issue, but no luck.
I am downloading the L720VPUAMF9_L720SPTAMF9_SPR.zip from sammobile per your suggestion and will give that a whirl. I borrowed a cell phone from a friend who has an extra month of contract with another carrier he is leaving - so actually have a phone to use during this 'downtime' for emergencies - but am begining to wish I had kept my old EVO 3D which never missed a beat. Okay, not really - I like my wifes functioning S4 so far, and her has been fine. I don't even want to think about how stressed I would be right now if it had been her phone that took the dump instead of mine! She simply wants to turn it on and have it work and only appreciates any modifications when every now and then she uses something in front of one of her friends who comments 'cool' I wish I could have/do that with my phone (like hotspot on the boat to a kids tablet).
No luck - bricked or dead phone...

Downloaded and tried L720VPUAMF9_L720SPTAMF9_SPR.zip from sammobile. Odin process went flawlessly as always, no errors, started process after clear cache and factory reset - followed by battery removal for 10 minutes, then turned on phone directly into download mode and odin''d. Re-boot revealed same behavior, tried clearing cache and factory reset again, then battery removal, no luck - looks like I have an unrecoverable phone :crying: At this point I have samsung recovery and firmware so it's going back. I will give my replacement a good week to wring itself our before trying anything with it. On a positive note, my wife's S4 which was an exact replica of this unit continues without missing a beat. This gives me some confidence that it wasn't CF root process or CWM recovery that caused this issue. I am still very nervous going forward but after 6 phones and 3 tablets successfully rooted with custom recovery and no other issues over the last 2 1/2 years i would like to think this really was a hardware failure.

No garantee, but I had rooted mine before it went haywire and bootlooped. When I took it in they had the phone for 15 minutes in the back out of my site - expect they went into download mode and could see it was not original (rooted) but replaced it anyway without any fanfare. BTW, after 3 weeks with the new device I rooted it as before - this time using TWRP becouse I had recently helped a friend root a tablet and used TWRP recovery - liked it so... In any case, I have had my rooted S4 (#2) running without issue ever since.
I made the mistake of encrypting my phone and am now paying the price. It is rooted and I had installed the Google Edition 4.4.2 ROM by Danvdh, Kryten2k35 & Ktoonsez. I'm using TWRP 2.7.0.1.
I first tried going into recovery and doing a factory reset and got the an "Unable to mount '/data'" error, followed by a big red FAIL. So I rebooted into the system and tried to do a factory reset from there. Went through all the steps, phone rebooted into recovery and I got the same error - unable to mount.
So I did a bit of searching on the forums here and someone had suggested using the format option in TWRP. So I did that and it seemed to work - did not get the dreaded unable to mount error. So I tried flashing the new rom (the updated version from a couple of weeks ago). Got a message indicating it was successful. Rebooted, and to my dismay, got the prompt for the encryption password. Saw the little line drawing Android, then... nothing - I found myself in brick land.
Managed to get back into TWRP and, based on another post I found, tried Advanced Wipe, selecting everything except Micro SDcard and USB-OTG. Tried installing the new ROM again, says successful, but nothing has changed - I still boot into blackness after inputting my encryption password.
Not sure what else to try. Any suggestions would be most appreciated.

Can you go into download mode, revert back to a stock rom (or flash a stock one or something) and turn encryption off? edit: on further research it looks like the only way to completely unencrypt is to reset your device. dunno if that's something you'd want to try, but considering you already wiped multiple times.. i'd say try it?
Also what carrier do you have? That's pretty important. AT&Ts i337 and Verizon's variant cannot flash AOSP roms (more specifically, kernels) due to the bootloader being locked. That might be the issue you're experiencing? I looked up the ROM and it's using ktoonsez kernel, so I imagine that'd be why. Someone just made a version that does not include the kernel and has multiple issues the ROM you're trying to use fixed here.

Thanks - that's exactly what I've been trying to do. I haven't tried reflashing back to stock with Odin though. Hmmm...

Bell, up here in the Great White North. I don't think locked bootloader is an issue - I was on the previous version of Danvdh's ROM, and everything was hunkydory. I just made the unfortunate decision to encrypt. Big mistake.
May try flashing back to stock. Nothing to lose, at this stage...
Thanks!
Hey just wanted to mention for the benefit of anyone else who got into this bind, flashing back to stock using Odin did the trick. Still wouldn't boot, but then I rebooted into stock recovery and did a factory reset, and finally was able to reboot back into stock. What a nightmare. Ugh. Thanks for the tip though - never occurred to me to try to go back to stock. Lesson learned though - no more encryption for me!

Good to hear. Should be able to flash to the rom once again no problem now that it's unencrypted!
Hi,
I was messaging a friend on my phone when all of a sudden it shuts down. Now when it reloads after the samsung logo I box pops up saying Unfortunately, System UI has stopped. I flashed lollipop over a week ago and everything was going great until now... Any ideas anyone? I tried to flash again but MMC_write fail at start. so no go. Odin sees it. TWRP is available but I cant restore since my restore point has disappeared. I cant mount anything besides system and micro sd. Cant get int Adb sideload either.
Thank you in advance for any help anyone can offer or lead me to an answer.

It fails due to the fact that it cant mount data, cache, or internal storage. Any other ideas? Man I wish it was that simple though would have been free from the stress last few days.
Thanks,
I got the same problem when i flashed cf root for kitkat on my SM-N9005 5.0 lollipop, i simply reflashed the stock rom via odin and problem solved

I was thinking the same, however everytime I try to flash something with odin it fails. On the screen it says MMC: MMC_write fail not sure how to get around this part. Sent to samsung tech guy and he said he couldn't either. any other ideas?
Is it ok on xda to bump a thread? if not my bad. Still desperately looking for an answer on this topic.
Anyone with ideas? It's been since feb and still sitting in the corner looking all sad.... IF all else fails is there a way to brick the phone completely so that Samsung will honor my warranty? Microwave? Oven? Something?!!?
Well this is my 1st post so first of all hey everyone
I just spent a week in Amsterdam and my phone restarted twice, different times different days and I dont remember what I was doing with it back then.
But as I landed back home I put the phone back from "Airplane Mode" and went on to toggle "Cellular Data" on.
The second I pressed the cellular data shortcut on my the phone restarted itself but this time whenever it would finish the screen would be on but fully black and sometimes it'll show battery precentage at the top but then will restart again in an infinite loop.
Sometimes it'll pop up the "Optimizing Apps" window and will go through all 24, upon finishing it will restart once more and do the same.
I tried using the bootloader and it worked (the bootloader that is) but the phone would do the same thing even after Rebooting from there or shutting down from there and then turning back on.
I contacted tech support on chat but they couldnt help past telling me to go to bootloader and reboot, said I should factory wipe when it failed.
Also tried wiping cache but to no avail.
I have no backup of my phone (wanted to do one before the flight but got lazy and I suck for not doing one sooner) since probably October and google doesnt backup my contacts properly for some unknown reason.
I already downloaded Android Studio with everything included for me to try using adb to sideload stock without wiping but its my first time and I couldnt get it to do anything at all...
I already got the official stock .gz file from the motorola website.
Anyway here are the specs to my phone:
XT1575
Everything is stock. didn't root or change recovery once in my life.
Was fully updated and had plenty of drive space (I have almost 128GB with the 64GB version + 64GB SD)
I'm really lost here so help will be very appreciated.
Thanks in advance,

Start with a full wipe and if that doesn't work flash the stock image. Not sure what your question is though as you never really say. Once fixed I would unlock and make a backup so you don't have to deal with this again.

The thing I pretty much want to know is if theres a way to either backup the phone now with it connected to the computer while in bootloader or recovery. or a way to flash the stock rom without wiping which I read someone did with his tablet. I cant post source normally because I'm a new user so here it is but change spaces to dots: schnouki net/posts/2014/08/13/flashing-a-stock-android-image-without-wiping-user-data/
Also while in recovery I noticed 2 options under wipe: 1. userdata only. 2. userdata+(insert something I dont remember here) and I was wondering what gets deleted in both? if I delete only userdata what data will remain? something helpful?
Sure you can try flashing without wiping data but being locked I personally wouldn't risk it. No idea about backing up in your state... somewhere I remember a thread on backing up without root try searching in q&a.

Out of curiosity why shouldnt I try flashing with no wipe if ill lose the data anyway? worst case wont I just have to wipe after it fails and flash again?
And I will try thank you
Do you have any knowledge about the 2 wipe options?
Thanks in advance
Well I tried turning the phone on and it took a couple of minutes before loading to a fresh start. It apparently wiped itself on its own. Managed to restore almost everything.
Anyhow the phone takes too long to boot now. Was even stuck at boot and I had to restart it.
Anyway to fix my software? Or at least check for corruption?
