[Q] PIT/EFS Backup of a brand new P6800 - Galaxy Tab 7.7 Q&A, Help & Troubleshooting

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.

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

Pit File Required - GT-P6810 WIFI (32GB)

Hello All,
Just wondering if anybody happens to have a .pit file for the 32GB wifi version?
Let's just say I didn't read instructions... and my tab is showing as a 16GB instead of 32.
Require a 32GB version pit file for the GT-p6810 to re-partition and get it back to normal.
Thanks in advance

Hi, usual disclaimer - use at your own risk. Here's why:
1) I extracted this from mine with heimdall, it is a binary so I have no idea if it extracted correctly.
2) I never flash pit, so this has never been used.
Suggest you compare with another poster before using.
Including the text version (also extracted from same device with heimdall) so you can see what is supposed to be in the binary.
Hope it helps

You are a legend. Worked like a treat, I've got a '32GB' tablet again.
Thank you so so much for your help. I'd buy you a beer if I could
Glad it worked! Enjoy your tab.
Cheers

Hi, I was wondering if it is this file (but then the 16GB version) of the pit-file that I should use and change in orde to increase my system memory?
If so, how do I get the correct pit file for my device, and how do I change it ?
Any idea's (or is my idea a stupid one ? it's just that my device is hellishly slow because the system mem is Always so low...)

[SOLVED] [Q] 32GB PIT for GT-P5100?

Hi All
I have searched and searched but can not find a 32GB PIT file for my GT-P5100 (obviously 32GB version).
I need this since I was stupid enough to use a 16GB version while flashing (I know, was pretty stupid hey?)
The tab works 100% with 4.1 JB, just minus 16GB worth of storage!
Can ANYONE please let me know where to find a 32GB version partition file? (the Sammobile site only has 8GB and 16GB)
- OR can I use another type Samsung Tab PIT file?
Thanks for ANY help...
EDIT: This is solved, read on to see some epic assistance!

			
				
Hi. Did you use a PIT file when you flashed the ROM? If not, then I think you don't need one to put back your original partitioning neither - just try to flash back the original ROM (if you made a backup), or a ROM from the Development section which is exactly for the P5100 32GB. At least that's what I would try, as using PIT file is very risky, especially from a different device model.
What ROM did you flash btw? If it's a custom ROM, you could also ask the developper for a solution.
UNless you actually flashed a PIT file or checked off the repartition flag in oDIN then nothing should have affected your storage layout.

Thanks for the help, I however did use the PIT file (still not sure why I did!) I also went back to the original ROM to see if somehow this would help. The Tab works without any issues, just partitioned to 16GB
I flashed with official rom, XXCLI5
oh, then I think you're right, using the original PIT file would be the best option... (unless there are system commands that allow repartitioning, but I couldn't find anything).
here you find some explanations about the PIT files:
http://forum.xda-developers.com/showthread.php?t=999097
then you might want to check this post, it gives a lead for a solution (even two - someone with unmodified partitions extracts for you the original pit file of the tablet, OR use this PIT file editor ):

Hi
I have a pit file for you because I have the same problem. To make a long story short I retrieved it from a working 32GB p5100. I varified the PIT file by using PIT Magic to compare it to the 16GB version. Unfortunately for some reason I cannot get odin to partition my P5100 with this PIT file. I assure you it is the correct file. See if you can use ODIN to install this file. If you are unsure if it is the correct file download pit magic PIT_Magic_v1.3.10_Release to varify.
Pit file attached !!!!!! Used txt to upload. rename type to pit
See if you have any luck repartitioning your internal SD. I think that if we can find the correct stock rom the re-partitioning will be possible.
If you can get this pit file to do what it is supposed to let me know. In the meantime at least we have the correct PIT file.

Thanks guys, will try this PIT and keep you posted...

For interest, what Odin version are you using? I tried with 1.87
Also looked at the PIT file in PIT Magic, as you mentioned it does look ok. (LOOKS ok, I also compared this with the 8gb and 16 gb versions)
btw, Happy 2013 all!

Heimdall http://www.glassechidna.com.au/products/heimdall/ has a utility to extract a pit file from a working device.
It works!!!

This PIT file really works!!! A great thanks to author. But, for it became work you need modify it. First, you need to change file ext from .txt to .pit. Next, open this file by any hex-editor (i used HxD editor for this purposes) and remove all zeros in the end of file (C6 D6 48 F6 must be last bytes in the file). Save file and answer YES in change file size dialog. Now size of file should be 2132 bytes. Now You can use this file by ODIN with repartition option checked. After programming You must to boot into recovery mode (power on with volume down buttons) made swipe\factory and swipe\cache. Now space goes back.
I tested this half our ago on my P5100 which I was programmed with 16GB pit.
regards
Just wandering : what append if you would use PIT from 32Gb instead of 16 on a 16Gb tab?

Here is the working pit file zipped after the input from the "RUSSIAN WIZZARD"
USE ODIN 3V1.7
STEPS
UNZIP ATTACHED ZIP P5100_32GB modded.zip
LAUNCH ODIN
SELECT PIT, SELECT REPARTITION, SELECT ROM OF YOUR CHOICE.
DESELECT REBOOT
UNPLUG AND REBOOT MANUALLY AFTER ROM COMPLETION BY HOLDING IN POWER AND VOLUME DOWN INTO RECOVERY MODE
DO FACTORY RESET
YOUR P5100 SHOULD NOW BE A 32GB TAB AGAIN.
ALL THE BEST

[Q] Rom backup in .tar.md5 format

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.

[official][stock] sm-g360v

DISCLAIMER: Since this is a third-party supplied file, flashing this file places any and all outcomes on YOU, the flasher (get your mind out of the gutter, thanks.) This file, though supplied by Samsung Kies 3, may cause issues or have undesirable effects. What these effects are, I have no clue. If you have a custom recovery, it will be overwritten with the stock recovery. Again, if you use this, you are the one responsible for any negative outcome.
​This the official stock ROM flashable via Odin. This took me a few hours to download several times and locate the temp directory that housed it. It is a 2.12 gig tar.md5 file. Since Samsung does not have an open source copy for us to download, I used Kies 3 to download it.
FLASHING INSTRUCTIONS:
Using the most recent Odin, put the file in the AP section and flash it.

Thank you so much it fixed my bricked device!
Thank you so much - Accidentally upgraded firmware and lost root and could not re-root. Worked like a charm and used kingroot to gain root again. You rock!
It downloads as a .RAR file if converted to .TAR, ODIN can not load it. How can the .rar file be used by ODIN?

The flashable .Tar file that you will use to restore your device via Odin, is located inside the .RAR provided in the download link. Once the .RAR file has been unrared/unzipped using 7zip, you will have your restore .Tar file that you're referring to. If you need to, you can Google 7zip and download it. The program is free and open-source, and it supports .RAR .TAR .ZIP etc. Happy Restore!
@jaywillsoul Please add to the OP that this firmware will wipe the device.
Thanks again for the firmware!

Fail
I downloaded the firmware, began to flash and Odin wrote "FAIL", and the screen after turning on is "Software update failed. Your device didnt update successfully. Use the Verizon Software Repair Assistant on a computer to repare your device and complete the update." But the Verizon Software Repair Assistant after this can not find the phone.
Thank you for this wonderful gift to the underdeveloped Core Prime! :good: worked for me and I was able to root afterwards!
is that process unlock the sim card lock for Verizon
ty it work's. I can root now
Sorry to bump this thread, but will updating through recovery mode end up wiping all the data of the phone? (like pictures, and files)
I was dumb and didn't enable usb debugging before my phone got soft bricked, now it freezes on the carrier animation
My phone is a model SM-G360T1

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
