I finally got my SGH-i337 flashed with a AOSP GPE 4.4.4 ROM. I finished setting everything up. I'm rooted, running safestrap recovery, got all my apps installed and themes set. I decided it was time to encrypt. Went through the default method in settings. Settings > security > encrypt. Set my pin and started the process. I went to sleep while the phone did it's thing. It said it was going to take a couple hours. I wake up and it has stopped on the boot screen.
Usually when I boot the phone it has four swirling balls that come together and form 'android'. Then 'android' flickers for a couple seconds and throws me into the lock screen. Now the 'android' just continues to flicker and hasn't changed for over an hour. So it was time to consult the forums.
Don't know if this is relevant, but whenever I hold the power button to turn it off while it is stuck I get two quick vibrates then it turns off.
If I enter safestrap, I am prompted for a password. I enter the PIN I set before encryption and it tells me "Password Failed, Please Try Again."
Everything I try to do in safestrap ends with:
"E:Unable to mount '/datamedia'
"E:Unable to mount '/ss'
"E:Unable to mount internal storage"
I used Joe-Tech's guide to flashing GPE 4.4.4 on samsung galaxy s4 from at&t. Can't link it, just made this account.

I am stuck in an installation loop that started while updating to KitKat.
I was happy with my LG G2 (T-mobile, D801G), but wanted to use root apps. So, I rooted and installed TWRP, but did not flash a custom rom.
Tuesday when I woke up there was a message saying I could download KitKat. After installing my last system update I lost root, so just had to unroot and re-root – took me about 15 minutes. So, I decided to go ahead and install KitKat.
It downloaded and began to install, but got stuck in a loop. The LG logo flashes for 5 seconds, the little droid pops up with his stomach spinning and the message “Installing system updates” but shows for only about ½-second. Then the screen goes black for 2 seconds and it starts again.
I can get it into the factory reset screen, but when I say yes-yes, it puts up the message :
Error: Boot certification verify
341120
341170
341220 Secure booting error!
341270 Cause: boot certification verify
341320
341370
(the nunbers are different each time, but always 6 numbers in increments of 50)
Then it sits in a black, but not quite off screen until I hold down the power button to turn it off. When I turn it back on, it shows the logo, then the droid showing the message ‘Erasing…’ for a full second, then switches to the ½-second ‘installing system updates’ loop.
It will go into download mode. When I connect it to the LG flash tool ‘Up Test’ it says all firmware is up-to-date.
I tried this: http://forum.xda-developers.com/showthread.php?t=2582142 but I couldn’t get Ubuntu 12.04 to install gdisk. Then I noticed that
ls /dev/sd*
returned the same values whether my phone was plugged in in download mode or unplugged completely. The values were
/dev/sda, /dev/sda1, /dev/sda2, /dev/sda3, /dev/sda4.
I tried the next step anyway
gdisk -l /dev/sdb
and got the error saying gdisk was not found, but I could install it with… etc. I tried to install it, but it wouldn’t work.
This is the second phone I’ve rooted – I had my HTC Sensation rooted for years, and flashed many ROMs. I hadn’t played much with the G2 because I liked it just the way it was – but had to have some rooted apps. I also have an HP Touchpad running Cyanogenmod. My experience with Linux is limited. So I’m just one step up from a noob.
Any advice would be appreciated! I bought a go phone so that I can take my time and fix my G2 right. :-/
In advance, I normally try to fix problems myself thus I dont post much, so I'm sorry if this is in the wrong area. I have already spent about three hours researching and trying to figure this out.
I've gotten sick of the loads of Verizon bloatware slowing down my phone, so I finally pulled the trigger to try safestrap. I'm using the ME7 build so that was the only option.
Safestrap installed without a problem. I flashed Hyperdrive successfully, but the ME7 modules available here would fail to flash even after I checked the MD5. I flashed from another source here successfully.
After all of this, when I boot the phone into that module, it will go to a black screen after the "safestrap enabled" logo. After about a minute, the phone will vibrate, show the Samsung logo, and then go into ODIN download mode.
The only thing I can do now is hold the volume down during start up. This loads a warning about how installing a custom OS will catch your phone on fire with a continue option (which results in the ODIN block), or a Cancel option (that restarts the phone and shows the safestrap logo before going to the black screen etc.) From this I can change the boot default to the stock OS if I choose, but I still cant use Hyperdrive. I have already tried deleting the ROM slot and starting over, but that didnt help.
Thank you so much for the help!
Edit: I tried bonestock and just got a black screen.
Edit 2: I also tried google edition and it would go to a black screen, restart, and loop again.
hi, i flashed a custom rom yesterday (http://forum.xda-developers.com/show....php?t=2794546) the super slim version.
everything worked fine. wanted to encrypt the device, charged it and pressed start encryption. it showed me the green android guy for a second, then rebooted. i went to sleep. today i see its giving me 3 notification on the screen: settings has stopped, interface stopped, and telephone stopped. i can press ok, then the screen either goes blank and nothing happens but the notifications pop up again after some time, or it reboots and does the same. i can still get into recovery, but /sdcard is inaccessible. should i flash from the external sdcard?
should i flash something with odin? i just want it back working. thanks
update, read at the bottom.
Hi, I have a Samsung Galaxy Note 4 SM-910C which I have rooted after flashing a stock Samsung rom. If I recall correctly, I flashed a stock android 4 rom trough ODIN, did it a CF-Auto-Root and eventually updated android 5 through wifi (OTA). SuperSU was installed.
I have attempted to do a native full-disk encryption trough the default Security menu; the phone went into a black screen with a green outline android robot in the center, with no progress bar or text of any kind (I found the image online, but can't post it due to account lack of privilege) . It has been on this same screen for over 8 hours now.
The device was NOT in USB-debugging mode.
What are your suggestions? Should I try some kind of reset? Is it possible the process will resume and is taking so long due to the amount of files? Or I shouldn't expect it to work since I tried encrypting a rooted device?
I'm not worried about any files in it, but I'd like to make sure to be able to recover the phone without bricking it. I'll be leaving the phone plugged to the outlet and untouched for the foreseeable future...
Thank you very much.
UPDATE: I powered off the device (had to remove the battery) and when turned it on again was met with the "Encryption unsuccessful" screen. Then I turned it off and went into recovery mode by pressing and holding POWER+VOLUME UP+HOME. Even tough it displayed a warning - dm-verity verification failed - I chose wipe/factory reset and then rebooted the system and it seems to have worked fine. After the start splash screen and a notification that is was installing applications (bloatware), it brought me the Welcome to Samsung Galaxy configuration wizard.
I have a stock moto x play whose hardware sku is XT1564. It's on android ver 5.1.1 and system version is 23.21.25.lux_lra.en.US
I have not performed any soft mods or alterations, be it root or bl unlocking.
The only thing that I would think is different than normal is that the phone is encrypted, so it asks for password whenever it boots up.
I got a notification to update to 24.74.5.en.US a few days ago and decided to try doing it today.
It downloads the update fine and when I press on the notification for it to start the update process where it says it needs to perform a reboot to update it goes into a "phone will reboot in 10 seconds" screen and when countdown finished it shows the "shutting down..." popup that appreas when you try to shutdown the phone.
Then the phone stays with that popup until it finally shutsdown like 4 minutes later on what appears to be a hard shutdown because it doesn't reboot. I have to manually power it on and then the phone starts up normally asks me for my password and about a minute after android fully loads the phone tries to shutdown again without any input. And then it just keeps doing that until I boot the phone into fastboot and try to get it to bootloader, where it shows the dead android logo with a red yield sign and promptly shutsdown. Then when I start the phone normally it shows an "update unsuccessful" screen.
Anyone have any idea what might be the problem?
I've been thinking it might be the encryption but IDK. Also I've checked the thread with the firmware versions and couldn't find mine there. Is there a way I could dump mine for backup in case I **** something up trying to get OTA to work.(without unlocking bootloader and rooting, of course)
Now the update has stopped appearing and I can't get it to recognize there being an update for this device.
Fudge!
