I dont have access to a linux box and I think in order to flash the latest JMA firmware from samfirmware i need to extract the rfs files in order to load them up via odin...if im completely off please disregard or point me to the correct path..
if any helpful souls out there that wouldnt mind extracting the files and uploading them here?
thanks
Im just a noob trying to flash the latest JMA firmware on my JM6 tab
thanks again..
EDIT - Thank you all for explaining it:
For anyone else presented with the same issue; use the zipped JMA file in odin in the PDA box and the pit file located at the bottom of the samfirm page when flashing the latest JMA firmware.

Extract them yourself by opening the file with 7Zip or WinZip. They're just archives.
Also - Should be in the General section.

thanks for the tips. I just installed both winzip and 7zip and could not extract the factory.rfs file with either.....
im guessing I have to extract the factory.rfs file and zip as a tar file for odin right?

The file you download is a zip file. Unzip it. There should be a tar file in there, tar is an archive format (similar to the way zip is, only it's uncompressed), so use 7zip or other unarchiving software to untar the file. There will be all of the JMA files including the RFS images contained in the tar file.

I see, so i downloaded a ziped file from samfirmware with the JMA firmware, unziped it down and got the pit file but there were no tar files in there for me to use in odin under the PDA box.
when flashing JMA what file do i put in PDA box? i pressume thats the only file i will use besides the pit file given that i dont want to replace the modem (phone) file...
I'm sorry if this is not making any sense

Use the JMA file here on XDA. Extra JMA.tar. Select that file ALONE as PDA. No repartition, PIT, Phone or CSC. It'll update PDA, Phone and CSC automatically.
If it doesn't reboot on its own after flash is complete, reboot into recovery.
You should be upgrading to JMA from JM6.
If you still need to extract/unpackage RFS->
Reffer to my guide here

why you do not try with a program to open tar files?

the zip file you can extract it, right?
Hi i have a question about using 7zip to make .tar files to flash with odin. For example, if i want a earlier modem version in my phone, and i extract the modem.bin from a earlier software and put it onto my desktop. I have the option when i open 7zip to select the modem.bin and convert it into a .tar by using the add key and changing the file type. Is this safe to do? I've seen alot of people using cywin and stuff, but 7zip seems like its much easier.
thanks
Many people find this issue while flashing stock frimware via Odin That after system.img is done Odin gets failed so I came up with a fix.
1) On pc open the firmware with winrar (or any other software like 7zip)
2)Then extarct the file named hidden.img from it to any place.
3) Rename the hidden.img file as hidden.img.tar . 4)Reflash the frimware through odin
5)You will get failed again but now flash the hidden.img.tar with odin now it will be successful and your phone will boot.
If the problem is still there or anyone needs to ask something qoute this post and not the whole first post (please)
@naimrlet mention this in the master thread too
This problem also occurs when you are flashing a different stock frimware for same device (e.g. different country firmware for same device) like people flashing aol1 for g531h to make s6/j7 mod by @ERICKONIX, work. This fix will also work that case too

Doing this is the same as not flashing the Hidden partition. You can't just rename it, you need to tar it. Just use 7-zip for it

No it involves flashing the hidden because if you rename with the extension it becomes tar. But sometimes you need to turn an option on the pc to see the extension but to know that it became tar when you rename it, the icon changes from winrar to the icon associated with tar files

Nah no need to tar it just rename
I've downloaded the latest firmware from Sammobile for my phone (G950FXXU1CRB7_G950FOXM1CRB9_BTU.zip - no carrier, UK) and I'm now trying to flash it. I tried to use Flashfire, but it doesn't run properly (it starts up, runs through some checks and then just returns to home screen), so I figured that, being a Linux user, I'd use Heimdall. I do have TWRP on the phone, but, as far as I can tell, the files aren't compatible for flashing with TWRP.
I unzipped the zip file resulting in a bunch of tar.md5 files, which (based on a guide I found online) I renamed to .tar files:
AP_G950FXXU1CRB7_CL12993647_QB17006525_REV00_user_low_ship_meta.tar
BL_G950FXXU1CRB7_CL12993647_QB17006525_REV00_user_low_ship.tar
CP_G950FXXU1CRAP_CP8821295_CL12993647_QB16754748_REV00_user_low_ship.tar
CSC_OXM_G950FOXM1CRB9_CL12993647_QB17217244_REV00_user_low_ship.tar
HOME_CSC_OXM_G950FOXM1CRB9_CL12993647_QB17217244_REV00_user_low_ship.tar
I then untarred these and got some .lz4 files ( a completely new extension to me):
boot.img.lz4
cache.img.lz4
cm.bin.lz4
modem.bin.lz4
modem_debug.bin.lz4
omr.img.lz4
param.bin.lz4
recovery.img.lz4
sboot.bin.lz4
system.img.lz4
up_param.bin.lz4
userdata.img.lz4
I assume I'm supposed to extract these using lz4?
Which files should I then flash? I'm assuming recovery.img will overwrite TWRP?

Yes you can use "unlz4" to decompress those. recovery.img will overwrite TWRP.
Excellent - thank you. Do I need to flash all the others? What about the modem_debug file?

Hi
How did you get on?
Im new to all this flashing and appeared to have bricked my Samsung S8 with the same AP_G950FXXU1CRB7_CL12993647_QB17006525_REV00_user_low_ship_meta.tar.md5 as you and im also on a Mac
Ive found that Heimdall is about the only software that will connect to the phone but just where does everything go?

I'm trying to do the same thing but whenever I use unlz4 or lz4 - d boot.img.lz4 I get an error "Error 64: Does not support stream size". I'm using Debian 8.11.
Can you tell me how you you uncompressed the files or what might be causing my error?
Cheers,
