Does odin delete all sypware or malware on the system partition? Does it completely format the /system partition? Or can viruses/spyware survive flashing stock firmware via odin?
When you reinstall the stock firmware back onto your device using Odin. It should remove everything including the System Partition.
Really? the reason I ask is because of threads I came across mainly this https://forum.xda-developers.com/showthread.php?t=2572693
This https://forum.xda-developers.com/general/help/please-help-super-virus-flashing-rom-t3363497
And this
https://forum.xda-developers.com/showthread.php?t=2573021
In the first link the person says odin overwrites system it doesn't flash it therefore malware/spyware can survive. In the second link the person asks whether odin wipes system and the first reply said "You didn't wipe everything. You didn't wipe the system partition". Finally last link person says he flashed via odin and a super virus remained. Are they wrong or is there another way?

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!
I'm trying to restore this Galaxy S5 back to stock but allow me to give some back story.
It was meant to be simple, I have the correct stock recovery files from samfirmware. I load up Odin and begin to flash it as routine. I watch as it goes through all the steps and checks out just fine, but right at the end when it flashes the Modem.bin it fails.
So I attempt to flash a modem file on its on first. Same thing, immediately fails. Saying auth fail in Odin.
Then I flash Philz onto the phone so I can wipe Partition cache and Dalvik to try again. When I was in there, I went to advance > and unmount /Firmware-Modem but all I get is ERROR MOUNTING /FIRMWARE-MODEM
I don't know if it's possible that it's hardware faulty [failing NAND as an example. The phone has some other strange quirks going on with it too]
Any suggestions would be amazing. I don't know where to go from here at all seeing as that seems to be the road block.
Ok I deleted system files via a wipe of EVERYTHING on TWRP - kind of stupid, but am selling the phone and wanted it clean.
Downloaded a stock (rooted) firmware, but when I try to flash with odin, it fails!!
HELP!!!!!!
What part does Odin fail on?
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.

Doesnt work another versions both twrp and odin. I'll keep my custom recovery and try it.

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.

Using i9500. And i did what you said and works fine thank you! Mods close thread please.
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.
