[Q] Little help with my S4 please! - Galaxy S 4 Q&A, Help & Troubleshooting

So i have a rooted galaxy S4, it also has a flashed rom on it (its an s4 rom but was manually flashed due to a few problems)
So I was wondering, is there any way for me to unroot my phone, but also reset everything else (I mean the flashed rom etc back to normal..., and just have my S4 like I just bought it?)
Any help would be appreciated, thanks!
-Eddie

in order to reflash the original rom you had, you need to have some former-flash informations:
-Android version you had before the flash
-Country of origin of the rom (not really important but if you want it really as you had it from factory you need this information)
Now what you need to do is to activate usb debugging from parameters : (Plus -> about device -> tap 8 times on baseband version, it will tell you that developper mod is activated, back to menu, tap developper options, tick usb debugging)
You need to download Odin 3.07 or whatever (i advice you use this one.)
and download the firmware you exactly want from sammobile (Warning, choose the exact model device you have)
then you need to factory reset your phone (via recovery)
now shut down your phone, put it on download mod (down volume + home button + power button)
press up, open odin on your computer then plug your phone to the computer. wait until your phone is detected in odin (a blue com will appear on odin). if your phone is not recognized, install usb drivers (google it) and turn off kies.
now extract the firmware you downloaded from sammobile, you will have a .tar.md5 file, click on pda, (or ap if newer odin version), then choose the file (it will take a long time to charge, if you don't want to wait, you can rename the .tar.md5 file to just .tar)
Click start and wait until "pass!" appears on odin.
That is all.

[GUIDE] Recover Samsung Device from Bootloop or Back to Stock Rom

I wanna share my knowledge here
Learning from my experience using Samsung's devices, I found similarities in the way of reversing Samsung devices to stock rom.
So this guide should be practice for almost all Samsung devices
Ok, let's get started
First, download all these stuff
1. Samsung USB Driver or go to this Thread (install it)
2. Samsung Kies (install it)
3. Odin v.4xx or Odin v1-3 or go to this Thread (just open when need it)
4. And of course your stock rom
Download from here (choose the right stock rom and the newest depend on your model)
5. Extract the stock rom using winrar/7zip
-you should 3 files PDA_xx.tar.md5, Phone/Modem_xx.tar.md5 and CSC_xx.tar.md5 or more
-If you have just two files, .xxxx.tar.md5 & SS_DL.dll, i'll give it the guide too
Second, Go to download mode
- For device with Menu button : hold power button+menu button+volume down (vol -)
- For device without Menu button : hold power button+volume down (vol -)
For the 3 Files or more
- Go to download mode
- Plug your device to PC/Laptop
- Open Odin
- Choose PDA (browse it from your extracted stock rom)
- Choose phone/modem (browse it from your extracted stock rom)
- CSC (browse it from your extracted stock rom)
- If there's more files, just put it on the same box of the files names
- Check list auto reboot and f.reset time(look at the left)
- Click start and wait
- If success, should be writen "PASS" on left side
For 2 files only
- Go to download mode
- Plug your device to PC/Laptop
- Open Odin
- Just choose PDA and browse it the file(forget about SS_DL.dll or XX.dll file)
- Check list auto reboot and f.reset time(look at the left)
- Click start and wait
- If success, should be writen "PASS" on left side
If there's something miss or wrong, please tell me, I'll fix it this ASAP
And Let's helping people
Why USB drivers and then Kies as Kies installs usb drivers .
Plus we already have all this posted in the faqs and guides .
OP, thank you for putting together this guide. However, there are already a few floating around with the same information, so I will close this one to avoid having a bunch of duplicate threads.

Soft Bricked Phone Help!

Hey all, new Android user here. I just rooted my device with no problems, but it dies and I recharge it, but it just goes to the "samsung" screen, and will vibrate 3 times quickly followed by another about 1/2-1 second later, then repeat every ~15-20 seconds. I am able to run it in ODIN (download) mode. I was told I need a new rom/firmware, can someone show me how to do this without ruining my device? I didn't save a backup because I assumed I would have no problems
I have had 0 problems before this, and even after root I didn't experience a problem.
Model: SM_G530T
FYI I am a mac user so have downloads be .dmg's.
Thanks in advance! If you need more info, tell me!
bump
pls help I want my phone back
You'll find your stock firmware on samsung-firmware.org
It'll be tar.md5 format, perfectly normal.
Add it into the AP/PDA in Odin and it'll flash fine.

Make sure all your drivers are installed, turn your phone off, plug the USB into the computer.
Start Odin (right click, properties, run as administrator and in xp compatability mode)
Put your phone into download ode (VOLUME UP, HOME, POWER)
Plug your phone into the computer. Odin will say "added" in it'd output box.
Press the button PDA or AP (depends on version) then select the firmware you just downloaded (tar or md5).
Once loaded into Odin, press start, it'll flash everything and then restart your phone.
Let me know if you need any more help!!
Edit:
Please ensure you are flashing the correct ROM for your phone. Bad firmware or recovery images can cause some bad problems.

Not that I'm aware of, but Google is your friend, friend.
Home + Volume Down + Power, that starts your phone in download mode which Odin uses to push software.
Your phone needs to be in download mode to do anything at all with Odin.
Also, why not just spin up a virtual machine and use the windows Odin, Windows is much better for all of this sort of stuff.

Steps:
1. Get to download mode -> Hold Power + Home + Vol down button.
2. Connect your device to your computer
3. Extract your rom, you will see, files, like AP, BL, etc..
4. Open Odin, go to options, disable auto-reboot.
5. Select the files, you will see buttons, on right side of the app,

It will take some time to load these files, so just relax and don't worry, you will be notified when it's done, with Added, log section. Especially AP takes long time.
8. Click start, and wait until the download is finished, because you have disabled auto-reboot before, it will stuck in download mode, and after u will see in log : Finished, all jobs done, something like this, you are able to reboot your phone, then you have to hold again the combination ( power + home + vol down ) to get out of it, to make sure you will run 100% clean, when the screen gets out, and it will boot again, switch the Vol down button to Vol up button, to get to recovery, erase data, cache, then do a reboot, first reboot will take a while.

For TWRP you will use the AP slot.. to change it's recovery.. after u swipe to allow modifications you need to flash dm verity.. to boot up.. and after the boot you need to disable OEM.. for what i know USB debugging isnt needed too much.. but OEM for sure.
And if you want to use ROM from your scard.. then just flash it via TWRP.. and I don't think that there is real way to skip first time Welcome menu.. this needs to be modified directly in the ROM. I think..

After the installation of the drivers.. connect without booting your phone to PC.. it will install some extra things.. so just wait.. until you will get Windows notification that they are properly installed... then boot to download mode.. connect it.. it should maybe install something too first.. so leave it installing it.. then allow download mode (continue) and wait until you will see your device in Odin, As added
IT WORKED!!! Can't thank you enough!!! The usb thing.
Getting a FAIL in odin.
I think it might be a bad USB cable because KEYS says - "bad cable" (or something like that), but ODIN will show connection.
Could it be?
I can go buy a new cable.

Please, where do you live.
Israel. Country code +972
Is your phone branded? Like from some operator..
Thanks. No. Not branded. From official store.
http://www.samsungmobile.co.il/
So we will use this ROM,
https://www.sammobile.com/firmwares/galaxy-s7-edge/SM-G935F/ILO/download/G935FXXU1DQE7/170029/
The code is ILO,
This is the right PIT file, you can find it on the link up.
SM-G935F OJK multi CSC ( CEL ILO PCL PTR )
by default : ILO
HERO2LTE_EUR_OPEN_HIDDEN150M.pit
Please download the ROM from Sammobile, try it again. If it doesn't help, we will need to fix the PIT.
Thx again.
I believe this is the file I have downloaded (see link):
https://www.androidfilehost.com/?fid=529152257862727613

EDIT:
only reason i download from androidfilehost website is because it's way faster
Okay.. so we need to fix the PIT.

Possible to downgrade from PIE to OREO?

My wife and I have ATT S8's which were updated OTA to PIE a couple of months ago and since then, we have been fighting with high battery drain. I've done several full complete wipes and even replaced the 1.5yr old original battery on my phone thinking it was bad, yet still, both phones drain with little to no use. By late afternoon, the battery is down to the teens.
I'm 100% convinced it's PIE, based on other complaints of battery drain since their S8's were updated to PIE.
So I want to downgrade back to a factory ATT OREO firmware. Both phones are currently on PIE version G950USQSDSE5. Can I safely downgrade to an official ATT OREO firmeware, ie. G950USQS5CRL1 or G950USQS3CRE2 using ODIN without the risk of bricking?
If so, what is the correct ODIN process to follow? I've read different instructions.
One of them reads:
1. Download and extract a zip file containing your desired firmware.
2. Open Odin Tool.
3. Boot your device in the "Download Mode": Press Volume Down, Power and Home buttons at same time for 5-8 seconds until download mode is active.
4. Connect your device to PC via the USB cable while in download mode.
5. Next, check the "Auto Reboot" and "F. Reset Time" options in Odin Tool.
6. Hit the AP/PDA button then browse and select a tar.md5 file from the extracted folder.
7. Finally press the start button to begin flashing the firmware update on your device.​
Another guide states:
Extract the firmware file you just downloaded. You should get 5 files:
AP (System &Recovery)
BL (Bootloader)
CP (Modem / Radio)
CSC_*** (Country / Region / Operator)
HOME_CSC_*** (Country / Region / Operator)
Add each file to it's respective field in Odin v3.13.3. Use CSC_*** if you want to do a clean flash or HOME_CSC_*** if you want to keep your apps and data.
Reboot your phone in Download / Odin mode (make sure your device is off) with the following button combo: POWER + VOLUME DOWN + BIXBY
Once in download mode, connect your phone to the PC, preferably using the original USB cable you got with your phone. Odin should detect your device and a BLUE box will show up with the COM port number. (Be sure, the SAMSUNG-drivers are installed on your PC!)
Do NOT tick any extra boxes. The only options to be ticked are F.Reset Time and Auto-Reboot.
Click the start button, wait for Odin to say 'PASS' in a GREEN box. Once the flash is complete, your phone will reboot, and you can disconnect your phone from the PC.​
Any help to get us back to OREO is greatly appreciated!
I was able to successfully downgrade, but even with disabling software and security updates, PIE forced it's way back onto my phone after a week or so. I need to find a way to block updates so I can go back to Oreo and stay on it.
Hey, I have the same phone and I am having an issue finding the correct firmware for it. Can you give me a link to the firmware you downgraded to that worked? I just flashed it with ODIN, but the firmware I used caused it to get stuck in a bootloop on the ATT screen and it wont turn on. Thanks!
I need to do this to my S8 Active. It finally went to Pie a few days ago and I cannot stand it.
