Question SM-A125F PGPT partition - Samsung Galaxy A12

Does anyone have a dump of the pgpt partition from their sm-a125f. i think i have written an incorrect/corrupted pgpt backup and need to verify the partition layout that should have been stored inside.
Thanks in advance.

I have a A12, how do you get that info? I can do it

thank you for your offer. i read mine back using sp flasher tool with pgpt partition set to download: true in the scatter file. however, i did manage to get a comparison to another pgpt this morning and mine doesn't appear to be corrupt after all. thank you for your assistance anyway.

[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
To backup my EFS partition, I thought of the following steps:

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

Actually the phone connected to PC in Qualcomm hs-usb qdloader 9008 mode. I tried to flash the programmer and bootloader via QPST. But It did not work. It ended with "Cookie(if present) was not received" error. Let me try the same procedure with the files you provided and tell the results.

[MTK][GUIDE] MTK based tools to customize/split firmware [Info]

So, some of you may have seen my work from the Android TV Platform, as i have done with AMLogic based devices im in the process of doing the same for MTK based devices, im making a full functional tool to disassemble and reassemble MTK firmware, suprisingly the firmware structure is very similar.
If anyone is interested in learning more about MTK firmware i made a video on manually splitting MTK dumped firmware HERE, so check it out, like and subscribe to my channel for more content!
What i have done
- Made a program to split an MTK firmware dump
- Split the ramdisk header to allow unpacking
- Unpack the kernel/recovery
- Unpack system
- Unpack cache
What i need help with?
i need the following info
- How to make an MTK scatter file manually
- How to repack the system with the proper partition length
- How to unpack logo.bin manually
- How to dump a firmware manually over USB without SP flash tool
Ive done some research already and dug in abit myself with no success, if needed i can provide code, binaries ive built etc to help with this

Hey mate,
Ive gota fair bit of experience with Mediatek,
Scatters can be manually created using notepad +
All you have to do is lay them out correctly, i can upload a few in a zip if youd like ive got variations of scatters from
MT6572 nand & emmc 4 - 5 diff models
MT6737M emmc from 2 models
With taking a backup also i use NCK_MTK_Dongle theres a cracked version aswell that works takes all partitions and backs them up into singular .file format files which depending on the fs layout are as follows
Preloader
Uboot
Bootimg
Recovery
Secro
Logo
Tee1
Tee2
Simlock
Frp
Scatter_File.txt
Just for some examples,
I use mtk extractor to take the boot/recovery/system.imgs apart and repack but its only compatible with ext4 format, can also compile an ext4 system.img from scratch using it aswell, specifically though i use it for the boot and recoveries as its specifically designed to handle the MTK headers, also has a nice pull layout that consists of the kernel as a whole, ramdisk as a whole, boot.img boot_old.img, bootinfo.txt and then initrd folder containing the entire layout of the boot or recovery with init files and fstab etc but ive also noticed it will unpack and repack Qualcomm, SPD & samsung boot.imgs no problem also,
Unpacking your logo.bin also can be done with the program LogoBuilder lastest version that was released is 1.6 you can decompile the logo.bin edit the pictures etc then use the program to recompile it back into a logo.bin
Hope that helps you out a bit

This info is somewhat useful, however im looking more towards a way of making a scatter file from a dumped firmware from a device, i see /proc/dumchar_info has some decent info, however some info i have no idea how its obtained
would you still be able to upload the scatter files for comparison?
As for the backup, what i wanna do is similar to what SP flash tool does, read from one memory address to another, i dont wanna use 3rd party tools either, i prefer to code them myself
I can unpack all that, and i can also repack the kernel, but the system im not sure how the size is defined, i may just recursively loop until a system.img larger than 2mb is created
Unfortunately that tool doesnt work with my logo.bin, ive tried but its pretty much a distorted image, and id like to code this myself aswell
Thank you for the info, if you can please upload those scatter files and ill keep you posted on the progress

Hey mate sorry for late reply im on aus time
Ahh i see what you mean now, im not to sure on how the system is defined to be honest mediatek is some what uniqe to say the least to me compared to everything else ive worked on before, ive noticed that aswell with fuzzy images in logobuilder inparticular on MT6979 the scatter though also had a very strange layout,
Speaking of which ive zipped up a few diff ones for you to use as reference, youll see some of the ways they are layed out is very different to one another as you will see defined within them,
https://drive.google.com/file/d/189H5EXS0ZqNuqn75A7ZNEOLo-Efq0T_h/view?usp=drivesdk

All mate good to see another aussie on here
All sweet for things to work it takes time to figure out how they work first before anything is even built then debugged, completely understand im just happy to see some more MTK support happening as most of my tools are 4-5 years old for mtk so i think its great
Ill be waiting patiently cheers

as i was saying most of the unpacking is done, the firmware structure is very similar to AMLogics(split the file from the start address to the file size in bytes), its pretty much just those few things i need, then repacking and i can dig into the GUI, id like to know more about how MTK droid tools creates a scatter file via ADB, it seems it uses some info from /proc/dumchar_info but that doesnt specify much, maybe the parameters are guessed???
ive attached a picture of my basic attempt to programatically create a scatter file, the highlighted lines are lines i dont know where this information comes from, nor do i know if those lines are the same for every MTK device

I think mtk droid tools also pulls info from
cat proc/mounts & cat proc/partitions
Aswell as cat proc/dumchar_info as ive noticed some mtk devices even MT6737M dont have dumchar_info available if that helps a bit, some mtk structures slightly can differ also in certain areas, will your tool support UBIFS also ? Forgot to ask been trying to find a tool to dissasemble ubifs

over time i can only hope the MTK community is like the amlogic community and have people send me devices for testing purposed, with AMLogic it was easy to obtain the info i needed because it resided in the firmware itself, i do however think this may be able to be done because mtk droid tools includes a feature where its able to split the firmware and create a scatter
As for ubifs, link me to the firmware and ill see what i can do, i should be able to do this
I just updated the thread with more information on how to manually split MTK dumped firmware, i will add more when i get around to it
Just an update, tools are coming along good, ive made substantial progress and upacking is done, generating the scatter file is coming together, repacking is almost done aswell, should have a release in about a week

Any advancement with this?
good morning my friends I dedicate myself mainly to hardware I have some phones with dead emmc I want to change it the question the question have you worked with the preloader? For example I have the mt6592 and I want to mount the emmc (emcp) KMRX1000BM-B614 with 3gb of ram and 32gb of rom EMMC NAME: RX1BMB and it is CSD rev: 1.8 (MMC 5.1) it cannot be changed in name, who could edit the preloader.bin

Thanks mate, but my situation seem worse, can't use MSM to restore since somehow, all partitions on device was deleted, that's why I need the rawprogram and patch xml to rebuild it.
Using MSM ( I tried many versions ) always leads to Device image not match ( I think it's because all the partitions are erased therefore it can't me matched with any kind of images ).
