Hello people my phone getting old i think 1.5 year so far my phone started to freeze having lags getting too hot while browsing. And bootloops started without flashing anything. First bootloop happened 2 weeks ago. Today happened again twice i wiped dalvik cache and everything is fine how can i fix it? I thought rom cause it i flashed stock firmware rooted it and removed bloatware. Still happens lags,freeze,getting too hot and bootloop. Is it lollipop update? I never had this issues with kitkat. How can fix this and keep my alive?

Try a full factory reset. Be careful as this will wipe your internal storage.

Thank you for your answer but I did it after flash stock rom via odin. Wiped data / factory reset , cache partition , mounted cache , system , data , wiped dalvik cache..
Wiping data does not equal a factory reset. Wiping data does just that, wipes user installed apps. But generally leaves the internal storage alone.
A factory reset returns the phone to the settings it came out of the factory with, including a clean internal storage(If you have the stock rom). I heard that changing roms and just wiping data, dalvik and cache will still leave behind some files.
But it could also be untrue.

Flashing stock rom is same with factory reset i think clears everything.
I don't know. Haven't flashed stock on this device yet.
But don't most guys recommend doing a wipe before going back to stock?
I dont know i'll try that when i have free time. I did research some guys saying lollipop causing these problems. I'll try wipe before flash stock rom again , if issues keep happen i'll use lates 4.4.2 custom rom. Thank you for your answers i'll report back.
Real reset
This method will wipe everything, including operating system and efs files. Before you do this:
you must root
Download twrp recovery
Install the recovery using the app from the play store
Boot into recovery mode and have twrp backup everything
save your backup to an SD card and the computer (can't hurt to have two backups)
Doing the above will preserve your phone important data like your imei and efs
in case something goes wrong.
NOW
after you have backed everything up use twrp recovery to wipe data. Have twrp wipe everything except for your SD card (don't won't to lose the backup)
After everything has been obliterated have twrp boot you into download mode.
Download Odin from XDA preferably 3.09 (most stable release) and then grab an official stock firmware from a trusted source. The latest stock firmware should be at least 4.4.2
If you have carriers other than t-mobile you will also need to find a PIT file for partitioning.
When you have all of this open up Odin with your phone connected in download mode and make sure repartitioning, clear efs and nand-erase is checked along with the defaults.
Select pda button and choose your firmware (unzipped tar.md5 format.) Then select repartitioning PIT file button and direct to where you have the PIT file downloaded.
now click start (be sure that the Com port is recognized by Odin: will be highlighted in blue or yellow.)
This will take a while depending on your computer.
when it finishes your phone should reboot with a fresh os and filesystem. If you get stuck in a bootloop reboot into recovery mode and do a wipe data and wipe cache. Reboot and your phone should be good as new.
IMPORTANT!!! It is vital you keep your TWRP backups for as long as you have your phone if you lose them and something goes wrong while flashing your phone you will lose important things such as IMEI baseband which will prevent you from connecting to your network and Sim card recognition.
Thank you so much i'll try this now.

Is that another custom recovery?
If so then yes just make sure you have all of your system files and most importantly your efs backed up.
Run odin as administrator if that doesnt work, try using another version of Odin.

What carrier are you using, model number of the phone, etc.
Have you backed everything up? And can you flash the custom recovery through Odin if it fails?
Try it without wiping efs first just to be safe
Look here for your device you will be able to find standalone flash able versions of twrp that should work through odin.

hmm i would probably try restoring sans odin...should fix whatever partition issues your having
I had to restore from KIES...
Wouldnt boot again.
Go in stock recovery and
Format data / factory RESET the thing...
WTH I almost tought i lost it for a sec !!
Never format data. What you should have done is odin back to stock, then factory reset through stock recovery. Kies is hit or miss when it comes to recognizing the phone in that state. You got lucky. There are a few topics on how to fix the problem you had.

I format /data every time I flash a new ROM and I experience fewer bugs because of it.
I just back up all my important files (data folder) to external SD and then restore after I install the new ROM. Works great for me. :good:

I'm mostly on TWRP but I do it in CWM also.
At most, your issue (whatever it was) was due to user-error or a random system glitch.
At worst, you have to ODIN back to stock which only takes about ten minutes to do, five minutes to re-root and install TWRP and then you're good to go again.
Don't know if any further research has been done on this subject, but it's the only thread that came back with TWRP+format.
This same thing happened to me last week, I *think* it was my first internal format on my i337, was able to boot then fail.
Odin back to stock fixed issues.
Any thought why this happens? Any suggestions for best clean format approach besides an Odin? Flash CWM/Philz for the format then back to TWRP if desired?
I'm currently stuck in the same situation. Used TWRP to format /data to try and clean up the internal sdcard and now I'm bricked. Flashed 3 diff recoveries and about a billion roms, nothing works. Downloading a fresh odin flashable stock rom as we speak.
edit: so flashing stock rom via ODIN wasnt quite enough. I then had to enter stock recovery and do a factory reset. I noticed any time I tried to format /data the system would crash and reboot. The stock recovery was able to properly format data and now I'm back on a custom recovery/rom again.
Whole Story:
I'm on a i337m Canadian S4 - Comes with Bootloader unlocked.
Last night I clicked "Format Data" by mistake in the newest TWRP - Lost everything - Could not do anything - flashing Roms did not work, so I downloaded a complete Restore of 4.2.2 from Sammobile and Odin 3.0.7 and was going to flash it back to stock.
About 1/2 way through the flash, something failed regarding a partition - Now my phone will not do anything other than display the below screen. It does not load a recovery, it does not go into download mode. Kies does not detect the phone anymore.
What can I do? Anything?
I'm so depressed over this.

From what I've read, Format Data using the newest version of TWRP deletes everything, causing everything not to work and is some sort of bug.
The ODIN Flash then failed after too.
I have the i337M Canadian version with the S600 Qualcomm
I've flashed via Odin dozens of times before with my previous Note II / S3 - never had one fail.

Can a cable cause this? I am not using the Cable that came with the phone - That wasn't included when I bought it. I'm using a Sony Cable from a Xperia T I used to own.

You can also ask Does god exist and what is the meaning of life.
Haha. I don't know. Such rethorical questions.
The cable matters because the other cable might not push enough current. Not sure. About the rest I have no idea. TWRP has a bug that's for sure. I don't use it. Check what adb says.
RESOLVED!!!
Tried my Laptop running Windows 7, and switched the cable. Also tried ODIN 1.85 instead of 3.07
Finally! This version of ODIN recongizes my phone.
3rd Attempt at flashing the firmware worked. The first TWO times failed.
Once it flashed, it froze, but factory rest has me back to Stock.
Now - to avoid that format Data button in TWRP, think I'll be giving CWM a try for the first time in years. Need me some Google Edition.

Wiping data, opposed to Formatting data.
TWRP FAQ
What to Wipe in TWRP
If you are switching ROMs (changing from one ROM to a completely different one) then you should perform a factory reset. A factory reset wipes data and cache (which includes dalvik cache). A factory reset will also wipe sd-ext and android_secure if your device has those items. 99% of the time, this is all that you need to wipe and you only need to do it once, not three times as some people would lead you to believe.
If you're installing a nightly update, then oftentimes you don't need to wipe anything at all. However, if you encounter strange behavior, then you may want to consider performing a factory reset. Of course, if the ROM maker recommends that you do a factory reset during an update, then it's a good idea to follow their recommendation.
The vast majority of ROMs wipe system as part of the zip install. This means that in most cases you do not need to wipe system... ever.
At this point, cache (not dalvik cache) is primarily used for recovery. It's used to store the recovery log and for storing OTA (Over The Air) updates. You probably don't need to wipe cache, and cache is already wiped as part of a factory reset.
In most ROMs, dalvik cache is stored in the data partition, so if you do a factory reset, you've also wiped dalvik cache. In a few custom ROMs, especially on older devices with small data partitions, the ROM maker may have moved dalvik to the cache partition to provide you with more room for apps. Since we wipe cache with a factory reset, again, you probably don't need to wipe dalvik. There are a few situations where you may need to wipe dalvik cache when installing updates, but you will know that it's needed when you are greeted with force closes when trying to open some apps.
Depending on your device and its configuration, you may have options for wiping internal storage, external storage, sd-ext, android_secure, and/or an option for formatting data. There's almost no reason that you would ever need to use these items. These options are there for convenience. For instance, if you're getting ready to sell your device, then it's a good idea to wipe everything on the device so that the new owner doesn't get your private data. Note that these wipe options may not be completely destructive. If you store especially sensitive information on your device or are really concerned about your private data, then you may need to look into other options to ensure that your data is fully destroyed.

Thanks - I realize this and am installing TWRP as we speak. (I just prefer it)
I was actually reading the Complete Guide in the general section and saw under CWM install that you need to format data between switching Roms.. I never actually did this ever with previous phones. Completely my fault for reading the CWM part, not the TWRP part, right under neath. I thought the Format Data was something S4 specific since this is my 2nd day with the device.
I'm now rooted with TWRP back on.
hey guys i was under the impression that if i flashed stock firmware using the pc version of odin it was supposed to format my phone to clean without having to use recovery to delete everything.
this isn't the case with me, odin pc (ver 1.85) seems to be dirty flashing these stock roms on my phone if i don't wipe in recovery.
is this right or is something wrong here?
I've seen the same thing. It doesn't necessarily wipe the internal sd card

That's the way all the version of Odin PC work.
That's why it's always best to go into recovery and do a clean wipe including data,
system, cache, dalvik cache and last but not least do a "Factory Reset" in recovery.
Doing it that way always gives the best results. (it does not wipe the sdcard)
Good luck!
Im planning to reflash my phone back to stock as a few things are messed up, will be flashing via odin the base firmware is UEND6 and will reflash the same firmware so that I can still root w/o tripping knox, would reflashing via Odin clear user data?
i guess not

I flashed stock over a CM install and forgot to wipe data. My stuff was still there but the install was definitely a little bit unstable with background apps crashing. It didn't wipe data, but the phone needed a data wipe afterwards to be usable...

Install TWRP recovery (will trip knox) and make a TWRP backup of the entire phone including data partition. Once inside TWRP recovery you can also mount /data and adb pull whatever data you need from it, including the backup. Not sure what to do if you need to access embedded app data that you can not pull through adb.
When I flashed stock without wiping data my files were still there though.

Still waiting for the download to complete. Samfirmware is only giving me 300kb/s and I dont know where else to get stock firmwares.
To close this issue with a resolved status, I would like to say one thing.
If you flash a leaked firmware - it will wipe your phone.
If you flash a stock firmware - it will NOT wipe your phone.
Factory reset will not wipe your internal SD.
Installing TWRP or anything unofficial will trip your KNOX. If your data is worth losing warranty - go for it
I was with a UEND6 firmware and just gonna flash the same to get my data back and factory reset the phone.
EDIT:
Got my data, everything seems to be perfectly working aside from the task manger, Gonna factory reset the phone and probably reflash with odin to have a clean start, would ticking repartition be necessary for a fresh install ? ( but I remember that required a PIT file )
Hi,
I set up TWRP 2.8.7.0 and cm-13.0-20160129 on my Samsung Galaxy S4 LTE-A (GT-I9506), and run into an odd problem where it would work after install, but would not work after a reboot (booting screen would just roll for ever). Installing CM again, would work, and than the problem would still be there. Mindlessly I decided to play a little anyway and set up encryption. The phone ended up rebooting, and not loading, so I'm here without a password (default_password doesent work) and with an encrypted /data that TWRP cant wipe or format
Unable to mount storage.
Unable to decrypt data
Unable to wipe '/data' -- unknown file system 'auto'
Unable to format to remove encryption

I've attempted to use ADB to format it, but it seems parted isnt installed. With that phone being a less popular variant I'm kind of afraid to just flash whatever there, but I guess I need a recovery with a least parted, or possibly one that would be able to format the drive itself. Any pointers?
Have you tried flashing a stock ROM via Odin? Is this your phone: http://www.sammobile.com/firmwares/database/GT-I9506/ ?
not yet; I don't have windows, and didn't see any point in changing the soft used for flashing, will try but cant download the polish rom at the moment o0 (ends up with a dead link or a server down?)
I know of no other way to flash a stock ROM from sammobile.com other than Odin.
Did you create a free account on sammobile.com to enable the regular download?

You can also flash it with Heimdall. It's the open source variant of Odin.
aaaand I'm back, managed to download, got some windows, flashed to stock using odin, and it's still encrypted. is running 'repartition' from odin safe? I've noticed some warnings against it but without any explanations.
edit; running the same operation with repartition failed. this bloody encryption might be able to survive nuclear war.
After flashing back to stock via Odin, did you perform a factory wipe before booting the rom for the first time?
I assume you have a pit file for the phone since you repartitioned?

never managed to do that. I wonder what advantage does the wipe from factory ROM have over custom recoveries... anyways thanks to all who helped, the issue is solved. also it seems that the problems with non-rebooting CM were my mistake of not wiping the cache/dalvik after install
I find that a wipe using a custom recovery is not always as through as a stock recovery. Can't say how or why, it's just based on my experience with Samsung and Nexus phones.

I think the difference is that a custom recovery only wipes /data partition so that the internal sdcard will not be wiped. The stock recovery formats /data partition. When you want to lose encryption you need to format /data partition.
You can also format the /data partition with a custom recovery, but that option is hidden for good reason. Because it will also format your internal sdcard and that's not something we want to do when changing roms.
