[Q] Rom backup in .tar.md5 format - General Questions and Answers

I read the article: [HOW-TO]Create Custom ODIN Images for Backup/Restore, and since I can't post there, I'm posting here. I have a USCellular Galaxy S3, model SCH-R530U. After reading the above thread, I used my ESFile Explorer, and found that the files that the dd command referenced did not exist on my phone. Does anyone have directions for making an ODIN compatible .tar.md5 backup of whatever I happen to have on my phone currently? I really need to be able to backup my current system so it can be reflashed again. Please don't tell me some other method unless it makes an ODIN compatible .tar.md5 file. If you cannot answer my question, I'm not interested in any kind of alternative. Actually, there is one other alternative. A way to make an ODIN compatible .tar.md5 file from a CWM backup.

[Q] Need help restoring ROM manager backup

Ok so I decided that I wanted to see what all the Froyo fuss was about, so I started getting my phone ready following instructions on the site. I own a Samsung i-9000m (in canada from bell - actually sasktel but we get phones from bell). anyways, I figured i'd do a rom manager backup. I did one, had some trouble with my phone and now I need to do a restore. Reading on the web they all point to an update.zip file. All I have is the following on my internal SD
ClockworkMod\2010-11-24-14.32.54\ and the following files in that folder:
cache.img
datadata.img
system.img
data.img
nandroid.md5
I tried restoring from rom manager but it doesn't find any files, I've booted into recovery but doesn't recognize the img files......any help would be amazing. Am I missing a step, google is no help
loooks like i needed the recovery update.zip file i'm assuming.....for some reason I didn't have it in the clockworkmod folder....

Need Help using ODIN & Tar file

Need help. I am trying to restore my Skyrocket to factory. I down loaded the necessary files
-ODIN
-SGH-I727-UCKJ2-k0nane
The thing is that when I open Odin, click PDA and browse, I don't see the tar file(SGH-I727-UCKJ2-k0nane)? Do I have to convert the file to tar?
The SGH-I727-UCKJ2-k0nane is in the download file and I see it but when I use Odin to browse, I don't see the file?
Am I doing something wrong or am I missing a step?
I am using Window's Vista. Does it make any difference?
I have read instructions many many times and I can't figure it out.
anyone out there?
Sorry bro. I would help you but seeing as I have yet to have my SkyRocket in Hand and have not gone through the rooting and ROM process on THIS device. I am not comfortable giving advice. Best to wait for someone who has more experience with the SkyRocket than I.

the .tar file is INSIDE the file you downloaded. the file you downloaded is a .7z or 7zip file. 7zip is a free archive/extractor. unzip it with 7zip and you will find your tar file.
i find it always helps to have your WINDOWS configured to show file extensions to keep confusion like this to a minimum, since you would have actually seen the file extension type.
careful! this method trips the ROM counter. why are you returning to stock?
I figuered it out. I bricked my phone trying to update to 2.36.

[Q] PIT/EFS Backup of a brand new P6800

Hello @all
since last weekend I'm also a proud owner of a Galaxy Tab 7.7 Wifi+3G 16GB (P6800). Now I have read a lot of threads about rooting,...
But at the very beginning I want to make a backup of all essential parts. In a first step this will include the partition table and the EFS Filesystem.
PIT Backup
=Q1=> Is it true that I'm able to get a backup of my partition table (PIT file) even without rooting my device?
=Q2=> Are the following steps correct?:
1) Put device in download mode
2) Detect device with heimdall
3) Download PIT with Heimdal
=Q3=> Can something go wrong with this method, or should this be absolutely safe?
EFS Backup
To backup my EFS partition, I thought of the following steps:
- Rooting the device
- Using some tool to backup the EFS partition (like KTool for the SGSII / Galaxy Note)
=Q4=> Is there a tool which can provide such a function for the Galaxy Tab?
=Q5=> Or do I need to do it manually, e.g. via "dd" and terminal emulator?
Best regards,
Chris

Think odin/heimdal only reads the file, it doesn't get stored anywhere on the phone..it should however come in the stock_rom_tar file.
Partition table

Just adapt rotohammers old tab7 commands to 7.7 partitions.. I dont trust any backup software unless it spesifies my device is supported
Just call out if something borks
Regarding the PIT file,
maybe I did not specify that one clearly: My goal is NOT to store the PIT file on the device. I want to download the PIT file to my computer, so I can use it in an emergency to flash a stock firmware with odin & repartition.
Best regards,
Chris

Here is the pitfile of the Galaxy tab P6800 which I got from the Samsung Service Center in after much request.
Hello Manipur,
thank you very much for your answer and the PIT file from Samsung. I will archive it, just for the case that I'm forced to flash my Tab with the Odin repartition option.
Best regards,
Chris
thank you so much for this file. after huffing and puffing for literally 4 hours with a soft-bricked p6800 i decided to adventure into unknown territory of the re-partition box in odin.
suffice it to say that i instantly revived the p6800 in less than 5 minutes with this file
THANK YOU THANK YOU THANK YOU

[Q] GT-P5113 modify stock firmware and flash question

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

Flashing stock rom for Samsung devices with Heimdall

Hello y'all.
I got this SM-A530F/DS, a galaxy A8 (2018), from a relative that got a problem. I am not sure about specifics, but it was never tampered with or rooted, I believe that things start to go bad after an unsuccesful OTA update. The phone does not boot, it just stays on samsung logo screen indefinetly, I can put the phone on download mode though so I think this is fixable by flashing the stock rom anew.
Now I got the stock firmware from sammobile and it seems good, but it is on a format for Odin, unfortunately I dont have access to a Windows computer, just Linux. So I got heimdall and read through whatever info I could find and I think I grok the fundamentals.
TLDR:
I have the following questions about the process:
1) Inside the stock files there is a .pit file that I assume is tailored to the stock ROM being distributed, should I use this .pit or should I use the one that I can extract from the phone with Heimdall?
2) The .img files seem to be lz4 compressed so should I first decompress those, or can I pass the compressed file to heimdall?
3) Inside the tar file for Odin {AP, BL, CP, CSC} there are a meta-data folder with a fota.zip file, does this file in any way influence heimdall flashing process?
p.s. I not sure if this should be moved to the device subforum as the questions mainly deal with the Samsung devices and heimdall in general and I could not find a Samsung sub forum to post this to
So I got the situation sorted.
1) The .pit file in the stock rom was the same as the phones, so I didnt have to do anything about that
2) The .img, .bin files must be decompressed first, not a great deal just had to 'lz4 -d' those
3) Those fota.zip didnt matter for heimdall, I just followed the phones .pit file to match partition names to partitions file and did a single 'heimdall flash' command
