Hi guys, i have a question...
Is possible create a custom rom (remove vendor apps) from XXXXXXXX.tar.md5 file downloaded from sammobile and make your own tar.md5 flasheable Odin file?
For example:
Original firmware:
XXXXXX.tar.md5
1.5 Gb
Removing vendor apps:
XXXXXX_my_firm.tar.md5
800 mb
I am interested in doing this without custom recovery, not zip flashable file, and not root.

Yes, you can do this, but things have changed a bit since this guide was written, you'll have to do some research to see what things have changed in this process from kit kat up to the current available android version. There have been some stock security changes that this guide doesn't cover and won't work with these new securities, but you should be able to figure out how to make this work with those securities if you learn to look in the right places.

This will help you create the .tar, you'll just have to figure out how to make the changes you want to make. You'll mostly be working with your system.img once you get it extracted.

New to Android, about 3 weeks now with my Rogers 1727R. I've been trying to grab all the good files and build my understanding of returning my phone to it's stock ROM if I have to return it or if I brick it etc. But I seem to have downloaded, from this forum, so many files, with different names and files sizes, I'm confused about what does what. So I'm asking any senior people here if they can tell me what I have, what it does, and whether I need it. Here goes:
Stock_ROM_SGH-I727R-UCKJ2-k0nane.7z - Think this is a stock ROM but un-bloated. It's 257 MB.
i727_stock_kernel_odin.tar - It's 10 MB, appears to be a stock AT&T ROM, but perhaps just the kernel, not the whole ROM?
Stock Recovery.tar - It's 6.08 MB. Downloaded it today.
Nandroid backup - 841 Megs with data.ext4.tar, system.ext4.tar, boot.img and recovery.img which I thought was a complete image of my ROM.
Look at the size differences. From 6 MB up to 841 MB. What the heck are all these files?

the .7z file is a 7zip archive of the stock UCKJ2 rom...you would need to use 7zip to extract the contents before flashing with ODIN
the .tar file you listed is indeed just the kernel, not the entire rom, and it is from the AT&T version
stock recovery.tar is exactly that. its the stock recovery to replace clockwork mod should you need to return to that.
your nandroid backup is the entire system, a direct image of everything you had on your phone when you created it. this includes all settings, installed apps, etc

So let's say I wanted to get back to my ROM the way it was the day I bought it. The Nandroid backup was done after rooting the day I bought it. So if I uncompressed the .7z file, is that what I would flash to get me back to square one, or the Nandroid backup?

the nandroid will get you back to the way YOU set it up. it wouldnt do squat for getting it back to stock.
the 7z file should take you back to stock.
its not complicated, you are just overthinking it.
a nandroid backup is YOUR backup, nobody elses. its an image of YOUR phone as YOU set it up. if you made the nandroid after rooting, and you restore from the nandroid, you will still have root, because its a direct image of your rooted phone. it will include all your settings, installed apps, and configurations.
That is very helpful. Last question.
What is a Stock Recovery file? You referred to it, and I see it's a rather small file, so it's not a ROM or Kernel. The name makes it sound like it's my stock ROM.
I know it has to do with CWM.
Any edification would be helpful.
Please keep questions in the Q&A section.....Thank you.
No recovery is not the rom. Recovery is like if u owned a computer around 1995 you had ms dos and windows well dos would allow you to make changes to windows that would not affect dos. Pretty much same thing. Recovery is where you flash the roms from but the roms do not change recovery. Cwm is clock work mod recovery . If you used odin to flash stock firmware tar tht woukd change your recovery from cwm to the stock recovery but i do now see we have a recovery tar where u can just flash the recovery tar but not the entire stock firmware tar.... to be honest id suggest doing alot of reading before you start messing with these things

Get on youtube and look up videos by qbking you can learn alot from them there for the epic not our device but u can more understand the basics if u watch them
I have spent several weeks working on this (reading thread after thread) on modifying stock firmware and im running into a problem. I more or less want to know if what i want to do is actually possible. I have downloaded the original .tar.md5 firmware image, opened with 7zip and "extracted" the .tar file (more or less just removed the hash) and then extracted the .img files from the .tar file. I have unpacked/mounted/modified/repacked using several methods (dsixda kitchen -which havent been able to work around adding the java path since after i add the path cygwin thinks im missing clean app until i remove the path in which case i get an error saying it cant find java/ i have tried mounting using ext4_utils in ubuntu) my issue arises when i take my modified and repacked system.img file i cant get it to work either by 1. zipping it in a .tar with the other .img files and flashing with odin, 2. zipping system.img alone into a .tar and flashing with odin, 3. installing cwm/root and flashing the system.img)
More or less my question is
1. is it possible to modify the stock firmware and load it onto the tablet without rooting
2. can system.img be flashed by itself or does it need the other .img files in the same .tar
3. does the tar file require being signed before flashing even with CWM recovery and root already on the tablet?
I have used these forums for a while to find answers, but i am new to posting, i havent needed to post a question until now since i spend as much time researching as i can before bothering people with a question (i like to figure stuff out and hate to admit defeat) Thanks in advance for the help despite my noobishness
Hello First sorry for my bad English. I have this file I8262XXBNC1_I8262ODDNC1_I8262DDNB1_HOME.tar a official firmware. can i use this to make a custom rom. I know that i can use a rom from this forum to change but i want to this project for fun, I opened it with winrar those files(photo below) and i saw that i need more files to do that. What you suggest to do?
Don't know well!!! But I think you can... just extract the firmware and found the "system" folder from there!!!
Press the Thanks button!!!
From my research i saw how to extract the files from the system but no way how to make one file again. I did that and i bricked my phone so i install again original firmware with odin.
If you have a pc... then use apktool to make and edit your rom!!!!
Or,
If you don't have a pc.. then install apktool in your device!!!
Install sygwin if you're on windows, then download dsixda kitchen or archi kitchen. Make it compatible for your phone and there you go...making flashable zips from official firmware with root, deodex, init.d etc.

Ok i will try it tomorrow
Okay, so I just learned how to extract system.img from KDZs, and how to extract the files from said system.img. Could I add all the mods I would regularly add to my phone to the extracted files, re-join them back to a system.img, name it rootedsystem and flash it with our phone's regular root flashing procedure (http://forum.xda-developers.com/g-flex2/development/lg-g-flex-2-ls996-zv6-sprint-5-1-1-t3169212)? It would make installing mods and re-flashing a whole lot easier to have a system.img with all my mods installed. Can I do that, or not? Thanks in advance.

I can't fully speak on it as I've never done it but it's not going to be as simple most likely. As you would need to also learn on how to make a .tot file. As You wouldn't be able to make it into a kdz as those are official.

I actually know how to extract system.img from KDZs, and the files from the system.img. I'm asking if I can just add mods to the system.img's files just like I would add mods to my phone directly, and then flash it.
Also, the part about just flashing it with root flashing works. You do the same thing for rooting but for another image.
Hello all!
This is my first tutorial here, hope to be useful as it was for me. After several attempts and extense research mainly here in XDA I finally achieved to downgrade my SM-G920I from 7.0 to 6.0.1 even with secure boot enabled.
The basics: Using a chilean stock 6.0.1 ROM:
- I've extracted all files from the stock rom and repacked it as 4 files without sboot.bin Instructions here: forum DOT gsmhosting DOT com/vbb/f777/tutorial-create-samsung-4-file-multi-firmware-your-own-100-a-1860706/- I've used a PIT default file for my model and region from here: sammobile dot com/forum/threads/30173-galaxy-S6-G920-pit-files
The instructions are the usual, Using Odin 3.12, flash the files into their respective slots and select the PIT file into PIT tab also. In options disable auto reboot and check re partition.
Download link in progress, but you can DIY with the instructions before.
downgrade issue can you give me the PIT file for sm-g920f please
also i have issue to back to nougat an error occured hidden.img durinf flashing

Have you downloaded a 6.0.1 stock rom for your model and then followed my instructions?
PD: The FRP for your device in on the second link mentioned before.
There is easier way ,after extracting delete all .bin (aboot cache hidden and something else cant remember)then repack using 7zip to the originat format u will notice that the new archive is bigger it's about 3.6 gb inside there is data,system and some other files flash the new archive with odin and thats all ,worked fine t mobile g920t downgrading from nougat to mm

Yes, you are right. Using 7zip is a lot easier.
Will work on Att version G920A with locked bootloader on 7.0? I've been researching 2 days to see about downgrading it 6.0.1 while taking least chances as possible. If answer is yes, when repackaging should I remove md5 extension on all 4 files?
Thanks
