[Q] S4 freezes all the time.

I haveS4 (i9505) that had the rom foxhound 2.0 on it.
I later decided to install the Google Edition (http://forum.xda-developers.com/showthread.php?t=2348272) on it.
When installing it I should have wiped data and cache but I accidentally used TWRP's "Format Data" function which deleted everything.
I had to use Odin to put back the original samsung software.
After this I installed the Google Edition the correct way.
When it booted up it said: "encryption unsuccessful" with a button "factory reset" which I pressed.
This took me to the recovery mode which also gave me an error (don't remember what it said).
So i used Odin yet again to put TWRP on it so I could factory reset the phone.
I used the phone for like 1 day but then strange things started to happen.
The phone just froze. Not like a normal freeze where everything stops, but where loading-animations still works and everything else stops working.
So I restarted the phone and it happened again and again and again. From like a few seconds to a few minutes the phone froze or rebooted.
The strange thing is that the same thing happens in recovery (TWRP), the same kind of freeze as described above.
And sometimes the phone refuses to turn on at all. Doesn't help to press all buttons, even holing the powerbutton for 1 minute doesn't help.
I have found out that when this happens I can disconnect the battery and reconnect it after some time to get it to start up again for a short time.
I've tried three different versions of TWRP, and also the original samsung firmware with the same result using Odin.
During all this I also had some problem with my SD-card. Files on it got corrupted and sometimes when i copied files over to it i didn't allow it to happen.
Anyone got any tips on what is going on/what i should do?

[Q] Continuous, consecutive reboots.,doesn't happen in safe mode any fix?

Hi!
I've got an N910C with Lollipop ( I did a factory reset after upgrading and cleared cache) . It randomly decides to reboot, and will keep doing so. After a reboot, I can use it for about a minute till it reboots again. Booting into safe mode fixes it temporarily and it stays fine after safe mode, a regular reboot doesn't help.
I'd prefer not to factory reset, and would like to find the cause (app/sd card? Sandisk 8GB btw)
Cheers, thanks!

My N910A does the same thing except the times it reboots can vary from a minute to an hour later, but it reboots a lot.
Doesn't happen in safe mode only regular boot mode. That tells me it's either an app or SD card.
I swapped SD cards and same issue. I wish there was a log I could look at to see what app is running at the time of reboot, but haven't found any logs that have that info.
I'm stuck and running out of ideas.

Try factory reset again man and remove Sd and try to boot it
You can identify where the problem come from

Screen Black out - Factory Reset is the temporary fix(HELL!)

I am have been facing some kind of weird issue from past few days. It made me reset my phone for bringing it's life back.(HELL)
I am on stock CM12 with stock kernel.(Didn't root)
Issue:
♦After regular usage(hardly 10-20 apps other than stock), kept it aside. When I tried to access mobile later, I unlocked the mobile, the capacitive lights at the bottom (Key guard) lighten up but screen was not awake.I waited for some time, but the problem persisted.
♦I pressed the power button for few minutes and mobile restarted.The screen worked until Cyanogen boot logo, the OS booted up, screen was kind of on for 5 seconds and the problem started again. I made many restarts but couldn't get rid of it.
♦Later I booted into recovery, wiped cache hoping it could rectify the problem but it made things worsen. After rebooting from recovery, the OS was now stuck on Cyanogen boot logo.
♦It forced me to wipe data/factory reset mobile from recovery which made the mobile work but with it's sole lost(Data).
It's quite frustrating issue as I faced it for the second time today in few days.
Please help if anyone knows whats the problem.

Not able to start from factory reset again, get's stuck or reboots constantly

hi...
I'm really desperate, my phone is suddenly dying and I have no idea why, I'll tell you from yesterday what has happened:
- I'm playing a stupid game and suddenly the screen goes black. No led, phone doesn't answer any button, nothing. I hold power button, nothing. Remove battery and put again, nothing. After some attempts phone turns on, but just after starting it reboots or stays frozen.
- I decide to change the rom (I had simpl rom), so I do a full wipe and put CM 12. It seems it works, but when I'm in the settings, at the beggining, I don't even have time to put the wifi, it starts rebooting again and/or not responding.
- Desperated, I install via odin the stock firmware from Sam Mobile. It seems it's gonna work, but when the dialog of "Android is upgrading -- Optimazitating app x of XX" it always gets stucked in a number, randomly. I never get to the 230 apps.
- As a last chance, I try Kies to install factory firmware. The same as before happens, but now it's only 17 the number of apps it tries to optimize.
These last 2 times, of course, I enter recovery from time to time (now the default one) and wipe cache partition.
My phone is agonizing, what the f is happening? Does anybody know what could happen?
Please help...

phone freezes at lock screen,

hi guys i have an issue with my device (i9500) since i had a bad efs partition which i successfully restored from a backup.
The device works perfectly, but as soon as you lock it, and wait a few seconds, you can't unlock it anymore. Screen stays black, and the only way to get it started again is by removing the battery. Then it keeps on working perfectly, apps, games, everything is fine, as long as you don't lock it (by pressing powerbutton or auto lock)
Either then it crashes or restarts.
Things i've done already:
- Soft reset
- Hard reset + cache wiped
- tried many different roms
- fresh stock rom installed with Odin.
Problem still persists.

Disable lockscreen till you find another solution.
