Hi,
I wanted to try LineageOS (19.1), which I did but actually I really want to go back to stock firmware.
Now I'm really having trouble finding out how to do that.
I have no Mac or Windows computer, just linux and I figured I have to use heimdall.
What I already did is
- get heimdall
- download stock firmware image for my country
- bring device to download mode
But then I'm kind of stuck. I printed the pit of the current situation. Then I go to flash and load that pit file, so far so good.
But when it comes to adding the bin and img files I'm kind of stuck at finding the right files.
Could someone please point me into the right direction. I've been googling for hours but I'm really stuck.
Why is installing Lineage OS so much easier? I just had to use adb to flash some zip files during the device being in recovery. Isn't there an equally easy method to go back to stock firmware?
Thank you so much.

Hi All,
I'm not sure if this is the right place to post this as I'm relatively new to posting on XDA. My girlfriend has a Galaxy S4 (I337) that I quickly and easily installed Cyanogenmod on. It's awesome and significantly better than TouchWiz. So, I bought an S4 off Ebay assuming it would be similar enough. It turns out this new S4 is an I9500 and before shipping it was updated to 4.3, which appears to lock the bootloader and prevent downgrading. I've tried Odin, Heimdall, ADB, Philz, Chainfire, Cofface, stock ROMs, etc with no luck. Today I did manage to root the phone and confirm root with TowelRoot. I'm wondering/hoping someone might have some resources to get CM on this thing. While I'd prefer not to brick it I am willing to take risks as I have a Razr (soft-bricked and unbricked) running CM and am relatively comfortable with computers/Linux.
I've been Googling and trying things for a month now and can't even find that much information on the locked bootloader. Any help would be greatly appreciated, thanks.

The I9500 doesn't have a locked bootloader. You just can't downgrade from 4.3 to 4.2.2 with official roms. Same applies when you are running 4.4, then you also can't downgrade officially.
Just flash a custom recovery true Odin and flash away.
Why would you even want to downgrade? Are you sure you are picking the right files? You cant flash the files for the I337 on the I9500. So just go to the section for the I9500 roms and flash away.
Hi Lennyz1988,
Thanks for the quick reply. I don't specifically want to downgrade but that's the last option I've tried. Ultimately the goal is to put Cyanogenmod on the phone. When I attempt to upload any file via Odin I get "secure magiccode check fail : boot" (or fail : recovery) depending on what I'm flashing. All the reading I've done says that when these phones are updated to 4.3 a fix has been applied that stops Odin from working. Thus, I my last resort is/was to try and downgrade. As I said, I've been Googling for the last month and while few people have posted about this I have not found any solutions.
Hoping someone might have a solution or anything new to try that I haven't tried already, thanks again,

Download the latest TWRP recovery:
http://techerrata.com/browse/twrp2/i9500
Fire it up in Odin under PDA. You need the .tar (DON'T EXTRACT IT).
If it fails:
- Different usb port
- Different cable
- Different pc
- Reinstall drivers
- Make sure Kies is not running the background.
Or you can use heimdall to flash it. Use the command line though:
heimdall flash --recovery nameoftherecovery.img (you need the .img instead of the .tar)
No luck there, Odin still fails with the same message. I have tried Heimdall on 2 different computers (4 different usb cables) and always get the libusb 12 error.
Since I have root access I figured I might be able to wipe the recovery partition from a terminal emulator. I copied recovery.img from the I9500 CWM to the internal sd card. I then went to /dev/block/msm_sdcc.1/by-name to figure out what partition is recovery, turns out its 21. I then did “dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p21”. I then booted into recovery and it just hung up. I had previously found a stock recovery partition so I flashed that via Odin (the only file I have found that works flashing via Odin). I could then boot back into the normal recovery. I then tried flashing both recovery and cache with the CF Auto files (cache is partition 18). Same result, it just hangs when trying to boot into recovery. At one point I did manage to flash a recovery that then came up with a warning about “software installed that is not supported by AT&T” and I couldn’t get past that so had to flash the stock recovery again.
On a side note, I accidentally wiped the EFS partition in this process (if found a tutorial that shows the S3 had recovery in partition 10, which is EFS on the S4). As a result 1.) the menu didn’t pop up when I hit the power button and 2.) wifi didn’t work. So, I made an .img of the EFS partition on my GT-I337 and moved it to the I9500 and that worked restoring both. In case anyone makes the same mistake.
I have now also used CWM ROM Manager and GooManger and tried installing recovery that way with no luck.
Just check if the internal memory partitioning is correct ( number, size and format) (use fdisk or parsed).
ODIN will install according to the PIT file and if drivers and cables are OK it is no other explanation than that.
PS: do not trust heimdall data because it just read the PIT file and do not give the true info from the memory part.!
Uhm on the TWRP website they say that the I9500 has it on partition 10.....
This would be the proper partition based on their website:
mmcblk0p10
Are you absolutely sure you have an i9500? Because my guess is that you don't.....
Boot into download mode. What does it say your model is?
Because on the AT&T it's partition 21.... So my guess is that you are messing up....
Thanks everyone for the input/feedback,
Something I think I had forgotten to mention previously, when the initial root/recovery attempts didn't work I downloaded an app to verify it is a genuine Samsung as I have heard of very good knock-offs. It is genuine according to the app.
Good point/catch regarding the location of the recovery partition. Under About Phone it shows as an I9500 and always has. When in download mode it currently shows as I337 but I wasn't sure if that was simply a result of all my attempts so I figured best to go with the one I am certain has been the same since I bought the phone. I had been hesitant to try wiping the recovery with for the I337 as that is how I soft-bricked my RazrHD (ultimately un-bricked it).
Tonight I will try the I337 files and see if Odin is successful. Thanks again.
Damn! Turns out my phone is an I337. The hardward (under the battery) says I9500 and when I plug it into a computer it shows up as I9500. On the weekend I thought I read that there is now the ability to flash recovery and install CyanogenMod on I337 if its updated to 4.4.2. So, I donwloaded the firmware and flashed with Odin. It flashed successfully but now I realize I am mistaken and 1.) cannot flash recovery, and 2.) cannot downgrade. For the time being I have installed Nova Launcher and removed as much of TouchWiz as possible. It's not perfect but at least usable. I'd like to start researching what it would take to flash recovery on this phone but I suspect I'm too busy at this moment.
Thanks everyone for the help,
Super simple...as a confident and tech savvy guy yet I have zero mobile modding experiance could I install stock andriod onto my note 4?
I already know about the hardswitch that cant be revsered the KNOX Counter, thats fine with me.
Is it something I could do or would it be hard to do...whats the basic process?
I can build and repair PCs and install OSes and trouble shoot common problems and all that marlarky...know my way around a BIOS ect.
As far as phones I have hard reset then vis there BIOS equivlent and cleared the cach but never more than that.

Rom has 5 parts, 1) main android os 2)Modem: it controls radios of your phone 3)bootloader: it supports booting up the phone, flashing *official* firmware , it will decide if a upgrade/downgrade is compatible basically works like BIOS but note that it will let you install only official versions of android signed by samsung, samsung official firmwares can be downloaded from website called sammobile, after you have downloaded a firmware in your pc it will be in the form of zip file, when you extract that file you will get a file in the form of .tar.md5 format if this file is extracted again then it will split up in parts like bootloader, recovery etc but you don't need to extract it again just flash the .tar.md5 file to Flash samsungs official firmware in order to do this you will have to enter bootloader's download mode on your phone this is done by turning off the phone then pressing volume down+power button+homekey on your phone the phone will boot into download mode will ask you to confirm firmware installation by pressing volume up key, *BUT* remember the downloaded firmware file is still in your pc so now to transfer and install it in your phone you will need a Pc software called "odin" just google "odin xda" and you will find download links, after installing and opening odin you will see it has 4 options BL, AP, CP,CSC (these are the rom parts i told you about you click BL and it will ask you to locate the bootloader you want to flash on your phone, click CSC it will ask you to locate the csc file you want to flash) but since we did not further extract our downloaded firmware we don't need to locate and flash these different parts manually if we just click "AP" and locate the downloaded .tar.md5 file it will automatically flash the whole firmware along with its bl,csc,cp and ap NOTE: First you have to put your phone in download mode then you have to connect it to your pc via cable and open Odin it will intimate you with a green box saying "connected " then you can go ahead and flash ur firmware 4)csc: this is country specific code, it enables/disables functions in the phone for eg the Samsung android firmware released in uk will hve its own csc and minor functions...and a firmware released in france will have its own csc and minor differences. 5) Recovery, this lets you clear cache, do factory reset etc in most samsung phones recovery can be accessed by shutting down phone and then pressing volume up+power button+home button at the same time and phone will boot into recovery mode. There is just an overview on how to flash different versions of "official samsung" firmwares on your phone before learning how to flash custom firmwares i suggest you learn how to flash stock firmwares first ( incase the custom os messes something up in your phone you will be able to get back to official software) There are many videos on youtube demonstrating how to flash official firmware via odin first watch a few videos on youtube before performing this.
NEXT: CUSTOM OS
Custom Roms like (stock android rom which is known as "cm" ) can not be flashed via Download mode which i talked about earlier in order to flash a custom rom you will need a custom recovery the official samsung recovery was limited to clearing caches, doing factory reset etc but these custom recoveries like TWRP, CWM have additional functionality which lets you flash custom roms (without entering and going through download mode) so in order to flash a custom rom you will have to download the custom recovery (i recommend twrp) for your phone's model from twrp.me (be careful install the one which is specific to your model or you could brick your phone) just download the recovery file in your pc, when you go to downloads section of twrp it will ask you to choose the format in which u want to download the recovery just download the one ending with .tar . Now to install this custom recovery in your phone, put your phone in download mode and connect with your pc and open odin, select "AP" option and locate the downloaded .tar recovery file and flash it. Now when you have flashed this recovery if you go to recovery mode (VOLUME UP + POWER + MENU while phone is off) you will see a different recovery than samsung's stock recovery.....this one will have many additional functions and options . At this point don't do anything just reboot your phone. Now that we have a custom recovery we can go ahead with downloading and flashing a custom rom to install a custom ROM follow the below instructions
> download the custom os u want to install (CM in your case) and place it in your phone's sd card, boot into recovery mode choose the option "install" it will ask you to locate the file, select the downloaded rom file and it will flash it. TADA...you will now have the custom rom running on your phone NOTE : again this is just an overview i suggest you watch videos on youtube and do alot more reading before doing this.
Very nice. I am in the same boat.
Coming from a Nexus 5 where we had android M and Flemental X which allowed for under volting and over clocking of both the CPU and GPU.
I want to root my 9100c which is on 5.1.1 but have some doubts about this complete Knox issue.
Still looking for good info on Knox. I dont care about my warranty. But what if Samsung releases an update say android M and it says you cant update because your knox is triped. ?
What are the best kernels for over clocking and under volting on the 9100c for the Nexus you could go with Franko or Elemental X on the stock Rom and you got everything you need.
Anything like that for the Note 4 ?.
Id like to keep the stock ROM, Root it and be able to under volt and over clock. Pls advise.
Huh this threads be merged or moved so not sure what happened to my reply but massive thanks for that explanation it helps a lot, I finally delved in today, its simpler than I thought but its also easy to make mistakes, I got a bit in over my head and almost bricked my note , and have learned it the hard way how to do some things, I thought there was only rom and root ^ and thats why I borked it mucking up kernels, and all sorts to the point I could only get into download menu, however now have a better understanding off it, and with a fellow member help I have restored my phone to stock, and will be installing CM13 from there.
Thanks again.
So, I've managed to soft brick my t355y, it hangs on the animated Samsung logo.
Since getting it, I updated from 5 to 7.1, flashed TWRP custom recovery and then gained root access using SuperSU successfully and the tablet was in perfect order. Then, I was attempting to eliminate bloatware via Titanium Backup (because not ONE CFW exists for this god damn model, NOTHING), I know for certain I didn't delete anything essential yet Titanium backup froze on 21% deleting the Samsung Internet app. There was no getting it out of that freeze but I could use the rest of the tablet. So, I figured I'd start from scratch and do a clean wipe, I booted into recovery and used the included tools to format the data on the tablet, being the idiot that I am I'm not sure, but I assume that was what caused the soft brick. Nothing that I do within TWRP will allow it to boot properly.
Now I've got no idea what to do, I've managed to track down a version of 7.1.1 under the carrier in my country and it fits the model number exactly. Though I'm getting mixed messages on the process for this, if I'm using Odin do I simply need to load the .tar.md5 into Odin and just go for it, or do I require a PIT file? If I do require a PIT file, it doesn't exist for the model I have, I've scoured everywhere I can think to look.
Any help in getting through this would be heavily appreciated. Thanks.
you must have deleted a crucial system app when you were getting all the bloatware out of the system..
If you still have the rom 7.1 try to flash that via odin in download mode. You will lose TWRP and root + everything else if you do a clean wipe.
Sent from my [device_name] using XDA-Developers Legacy app
It always amazes me that people won't take the trouble of a few minutes to create a backup with TWRP before messing with the OS. :silly:
However, are prepared to spend countless frustrating hours trying to resurrect their device.
My advice is to just flash the firmware you have with ODIN as is.
Leave all options at default and put the md5 in AP.
can you please post the twrp custom recovery flash file and , supersu file .
can you please post twrp and super su files please .
Any help in getting through this would be heavily appreciated. Thanks.

You can always use Kies for getting stock rom or updato . com (can't paste links). Samsung Smart Switch got rid of the device initialization, kind of sucks.
Soft bricked
I have also gotten soft bricked but have gotten out the way. First, you need a Samsung galaxy tab a tar file firmware. You can install it from the internet.If you have ADB use this command adb reboot bootloader and then your Samsung galaxy tab a will be on the download mode and then flash the firmware with Odin and that's how I unsoftbricked my Samsung galaxy tab a. You still need to do the updates tho.
Hello guys
My phone is Galaxy S7 Edge Duos- SM935FD. I seem to have bricked the device.
Below are the actions I have performed.
1. Flashed TWRP using ODIN as described on https://www.the***********.com/root-samsung-galaxy-s7-edge/
2. Booted successfully into the OS. Found superuser app installed.
3. When I went to back to Flash ROM i erased multiple things such as internal storage/dalvik/cache/system after which device got stuck in bootloop. Showing NO OS.
4. I tried flasing Custom ROM Zip files through OTG. The process failed showing package corrupt and still stuck in bootloop.
I can enter recovery/download mode however cant seem to get the device booted. How can I get the device to work either Custom or stock ROM.
I will be going through some threads in the meantime, your guidance is very much appreciated.
Flash stock rom with Odin: This shouldnt be posted on Development Forum but rayher questions and Answers.
Find what your Stock Firmware for your phone is using Sammobile and flash stock then re do rooting and TWRP Process
zzThrain is right -- I wouldn't risk flashing custom ROMs at this stage, especially because many contain new bootloaders or other stuff that might make this even worse for you. Just pick up the relevant Samsung stock ROM file (from, for example, SamMobile) and see if it boots normally again. Once it does, re-do the process *after checking all MD5s of the files you used* -- I, too, have had it happen before that a download went corrupted and I flashed it. If all is well, get into Download Mode and let Odin rip.

Go to recovery mode & transfer rom to phone using pc. wipe cache, delvikcache, data only. No need to wipe internal sd. Install rom & reboot.
if you phone goes to recovery or download mode, no need to worry. If it doesn't go to neither recovery nor download mode, them your phone might have probably bricked.
It's my pleasure to help you if you still facing this problem

Hi
I tried flashing stock rom from sammobile. I could find for SM-935FD hence downloaded SM-935F.
It got stuck at 90% showing System in ODIN.
From the ZIP file which is the file that needs to be flashed among below ? I tried AP.
AP_G935FXXU2DRB6_CL12365438_QB16944063_REV00_user_low_ship_meta.tar
BL_G935FXXU2DRB6_CL12365438_QB16944063_REV00_user_low_ship.tar
CP_G935FXXU2DRAG_CL648265_QB8691891_SIGNED.tar
CSC_OJV_G935FOJV2DRAG_CL12785220_QB16560277_REV00_user_low_ship.tar
HOME_CSC_OJV_G935FOJV2DRAG_CL12785220_QB16560277_REV00_user_low_ship.tar
Now when I try again it immediately shows FAIL. Am i Flashing the right stock rom ?
It Worked. Thanks to all who helped.
I wasn't running ODIN as Admin and also was using an slightly older version V3.10.7.
So I have tried 25 different ways using Odin, TWRP, 10 different files, etc. and cannot seem to get a stock firmware back on this device. Is there just a simple step by step to follow and download the correct files to allow me to get this thing back to factory?
Currently I have wiped the device and successfully installed and able to boot to TWRP but cannot get past this. Every time I try Odin (except to move TWRP) I get a write failed error.
Any assistance is greatly appreciated.
same for me, any hints on hiw to revert to stock rom?
