I have used 7zip. Just delete md5 extension first. It will be tar. Extract that

Making custom SM-G903F (GS5 Neo) LL 5.1.1 Pre-rooted Odin Rom (HELP)

Hello the community,
i'd like to ask you for help because i don't manage to make it.
Here is the problem :
1/ i flashed last firmware for the phone
2/ then root it, install latest busybox....
3/ dump from my phone cache & system using this :
dd if=/dev/block/platform/13540000.dwmmc0/by-name/CACHE of=/sdcard/cache.img
dd if=/dev/block/platform/13540000.dwmmc0/by-name/SYSTEM bs=4096 of=/sdcard/system.img
I check it using linux reader. No problem at all
4/ Then repack those 2 files with others files which are on stock tar file (boot, hidden...)
5/ Launch Odin, put my tar on AP then flash.
- All were ok until it came to cache.img then fail
On stock tar, there is a system.img (not .raw). Don't know if it is sparsed but....i suppose as it needs to be converted to bre used with linux reader.
So i dunno what to do to have a valid cache.img & system.img
If you can help me, i will be grateful.
Thanks for all.

Hi
I'm trying too making a pre rooted stock rom flashable through odin. But i get everytime a "failed" from Odin.
However why are using your cache instead of cache.img present in stock firmware?
Try unpack stock firmware and replace only custom "system.img" that contains root and finally repack stock firmware!

Well some info i need is in cache

why don't you make a flashable zip since you know the partions then add root

A stock firmware pre-rooted flashable through odin is more comfortable whenever you wanna reset your phone isn't need to using FlashFire or Mobile Odin. IMHO

Guys Please HELP

Can one of the people who have a samsung galaxy tab 4 (8.0) 5.1.1 SM-T337A (ROOTED) go out of their way and make a dump file including modem.bin, NON-HLOS.bin, recovery.img, a cache dump, and the PIT file PLEASE

Updating Rooted TWRP installed phone question

I used the flashfire method of downloading firmware and extracting ap file and flashing system and boot.img. Does anyone know or has anyone tried taking the ap file and extracting system.img and boot.img and flashing those image files via twrp? Twrp I believe supports flashing image files and that should work in theory. Thanks
Also is it important to update csc or csc_home files? I am learning Samsung coming from always owning nexus devices which are quite a bit different.

There's a thread which explains updating rooted devices with flashfire without loosing data here

Is there any method to convert stock firmware to TWRP flashable zip?

Here is a long story. Please read carefully before reply.
I have SM-G955N which is for South Korea. Also I have latest stock firmware that can be flashed with Odin. It has AP, BL, CP, CSC. With this firmware, I can recover from almost every problems(including bootloop) because these files have everything that my S8+ should have, even PIT file.
As you know, modifying stock firmware is very dangerous and you don't know what would happen if you delete/modify certain file.
You might think 'Hmm... I think it is completely not related to system or samsung so maybe I can delete this' but you can get bootlooped. I even got bootlooped by only deleting DioDict which is just dictionary app!
I think It would be much easier to recover from bootloop when I have flashable ZIP file that is pure stock firmware.
Maybe you can say 'Just use TWRP backup feature!' but I can't trust TWRP backup feature now.
When I flashed stock firmware with Odin and right after(after solving KG State thing), flashed TWRP. Then I should have pure, clean stock firmware because I didn't touch anything about system except recovery(TWRP), right? I backupped whole system except Cache because It has 0 MB size.
After I got bootloop while modifying system, I restored that backup but still got bootlooped. That's why I can't use TWRP backup as fallback plan. I can't trust it 100%.
There are few 'Kitchen' scripts but I think they only handle AP files. When I tried to use SuperR's Kitchen Free, I used stock firmware file(tar.md5) and didn't do any modification. After I made flashable ZIP file with it and flashed it with TWRP, I've got bootlooped because It didn't have critical CSC files that system needed.
I think the Kitchen can't handle CSC well even though It is critical. 'Donate' would be last resort.
I've found batch script that convert S9 stock firmware to flashable ZIP (at GItHub, 'harise100/S9-Stock-ROM-TWRP') but I don't think It can cover S8+ files. In the scripts, it requires some files that S8+ firmware don't have. Maybe I should play with that script to fit with S8+ but It will take a lot of time which I don't have much.
Any good idea or information about converting stock firmware to flashable ZIP file?
