Hello husq510
Thanks for this infos, i'll follow this thread closely because i'm looking for the place where ServiceMode settings are stored.

anyone tried writing to the bml directly?

interesting. so ive dd the bml4 and bml9 of optus australia stock 19000DTJF3. now anyone want to point me in the direction of creating an odin package out of it.

i whoner .... how can bml4 be the zImage? bml4=1.2MB, zImage=5.8MB ?? also if it should just contain the kernel without initram, it's still about 2.6MB? any idea?

you are right, cant be. then kernel must be in some other bml place, seems bml7.

Hello Folks.
I found some interesting bits in bml12.
"Service Mode" datas strings are in it, like show these example :
Code:
strings ./bml12 | grep Diamond

[SND]DiamondVoiceTXcfgMSG
`[SND] DiamondVoice_RxInit : DiamondVoice_Mode_v = 0x%x
Diamond Solution
[9] Diamond Solution
[SND]DiamondVoice_Config : DiamondVoice_Mode_v = 0x%x, Diamond_mode= 0x%x
strings ./bml12 | grep DEBUG

And I found my IMEI number in bml3
edit :
+ some MAC hardware address too (but not the Wifi one)
+ the HW Version : MP 0.800
I guess that bml3 is device-specific.
But I don't know if it's the source of specific values or just contains copy of hardware-related data.
In the first case, modifying bml3 would allow to change IMEI or other sensitive values ^^

nope, to extract the ram disk, u hv to find the magic number of gz and extract the gzip image out... i was able to get the directory listing of the ramdisk but not the content..
the other problem is after u get the ramdisk and do any modifications, u hv to reverse the process.. not an easy job but if anyone found a solution, please share.
anyone try writing to the bml directly? dd doesnt seem to work
anyway, its possible to extract the image and use odin to flash after tar but if can write to bml directly, clockworkmod can effectively backup/restore the kernel.. (just a thought)

No, you cant write directly to bml.
Data write to a sector involves following sequence of low-level flash operations:
1. Block copy for back-up
2. Block erase
3. Copy back for non-modified pages
4. Writing the sector data to the modified page
These sequences of operations are not atomic, so a write request to this block device driver is prone to data corruption. For this reason, read-only file systems such as CRAMFS are adequate to run on top of this block device driver.

use this small script to extract your current zImage:
offset=`dd if=/dev/block/bml7 bs=1 skip=44 count=4 2>/dev/null| hexdump -e '1/4 "%d"' -e '"\n"'`
echo $offset
dd if=/dev/block/bml7 bs=1 count=$offset of=/sdcard/zImage_backup

how do u extract this?
gunzip -c initrd-cpio.zip | cpio -i does not work.. gave errors

how did you dump and make the zip file you have attached?

[email protected] you have to use unzip instead gzip, cuz forum dislike .gz format, so I had to use standard zip.
mkdir initramfs
mv initrd-cpio.zip initramfs
cd initramfs
unzip initrd-cpio.zio
cat initrd.cpio | cpio -i --no-absolute-filenames

Hey, did somebody already tried to dump one or some bml partitions and restore them later ?
I guess this could be the ultimate backup tool.

I took a look into this and found that
bml2 : PIT file is here
bml5 : Sbl.bin is here
I opened it with a Hexeditor and compared with things from the firmware.
My device is running on JP3, froyo, at the moment.

thanks i will update first post. layout mapping is complete now!

[How to] Determine dd Parameters For All LG G4 Models

[How to] determine dd parameters for all LG G4 models
IMPORTANT:
Only for advanced users!
You are an advanced user if you know exactly what you are doing.
You are an advanced user if you know what to do if something went wrong.
You are NOT an advanced user if you know how to do copy+paste.
You can bring your smartphone into a state, so it no longer works.
I am not responsible for anything. The following instructions are only suggestions.
Hello,
everyone knows how to root the LG G4 with the "low effort root" method.
They copied the system partition to an ".img" file, rooted it and copied it back to the "system" partition.
Many users wonder how to get the right parameters for the "dd" commands.
Please read the complete guide and be sure that you understand it until you execute a command!
Information:
Code:
dd if=/inputfile bs=8192 count=12345 of=/outputfile
if = Input File
of = Output File
bs = Blocksize in bytes (default is 512 - to increase copy speed use multiple of 512 e.g. 8192)
count = how many blocks
skip = skip blocks before start reading
seek = skip blocks before start writing
more info: http://man7.org/linux/man-pages/man1/dd.1.html
There are different models of the LG G4 on the market.
We know that the system partition is different depending on the model of the G4.
As an example I will show you how to calculate the parameters for the LG G4 H815 (International Model).
What you need:
Windows with Send_Command.exe
Instructions:
At first we need to know where the "system" partition starts (first sector) and how big it is (partition size).
I used the first method to find these values. But I recommend the second method because it's easier.
First method (difficult method, extracting the GPT and using "gdisk" in linux to read the partition info)
What you need:
Linux with "gdisk" installed
Instructions:
Put your smartphone to "Download Mode" and connect it to the Send_Command.exe command prompt.
We need to copy the partition table to the internal storage.
The partition table of GPT (GUID Partition Table) has a size of 16384 bytes and starts at LBA2.
Each LBA has a size of 512 bytes. Because we start at LBA0 we need to add 1024 bytes.
In summary 16384 + 1024 = 17408 (bytes).
Execute the following command:
Code:
dd if=/dev/block/mmcblk0 bs=1 count=17408 of=/data/media/0/gpt_backup.img
Enter "LEAVE" to restart your phone.
You will find the (very small) file "gpt_backup.img" on your internal storage.
Switch to Linux:
Copy the file to your Linux and open the terminal. Then type this:
Code:
gdisk /yourpath/gpt_backup.img
Some warnings will occur. Ignore them.
You will see:
Code:
Command (? for help):
Enter "p" and hit "enter".
You will get a list of the partitions.
Scroll up a bit and check that you see:
"Logical sector size: 512 bytes"
Scroll down and look for the "system" partition.
You will find a line similar to this:
Code:
47 884736 9363455 4.0GiB FFFF system
Now you know the number of the "system" partition is "47".
You will see:
Code:
Command (? for help):
Type "i" and hit "enter".
You will be asked the partition number.
Enter it and hit "enter".
You will see something conatining lines similar to this:
Code:
First sector: 884736
Last sector: 9363455
Partition size: 8478720
Partition name: 'system'
We need the values from "First sector" and "Partition size".
Second method (easier method, just using "adb shell" to read the partition info)
What you need:
adb shell
usb debugging enabled
To get the "logical sector size" use:
cat /sys/block/mmcblk0/queue/logical_block_size
It should be 512
smason said:
To find in any smartphone the offset and the size of /system:
$ adb shell
[email protected]:/ $ ls -la /dev/block/bootdevice/by-name/system
ls -la /dev/block/bootdevice/by-name/system
lrwxrwxrwx root root 2015-01-02 10:50 system -> /dev/block/mmcblk0p47
[email protected]:/ $ cd /sys/block/mmcblk0/mmcblk0p47
cd /sys/block/mmcblk0/mmcblk0p47
[email protected]:/sys/block/mmcblk0/mmcblk0p47 $ cat start
cat start
884736
[email protected]:/sys/block/mmcblk0/mmcblk0p47 $ cat size
cat size
8478720
[email protected]:/sys/block/mmcblk0/mmcblk0p47 $
so:
offset = 512 * 884736 = 452984832
partition size = 512 * 8478720 = 4341104640
Cheers!

So "first sector" is the value from "cat start" (884736).
The "partiton size" is the value from "cat size" (8478720).
Now the mathematics (using the values from above):
Logical sector size = 512 (I never saw something different on LG G4 smartphones)
Assuming bs=8192
skip and seek: "First sector" * "Logical sector size" / bs
884736 * 512 / 8192 = 55296
count: "Partition size" * "Logical sector size" / bs
8478720 * 512 / 8192 = 529920
That was an example for the H815 (International Model).
Use your own values to calulate the "dd" parameters!
Back to Windows:
Put your smartphone to "Download Mode" and connect it to the Send_Command.exe command prompt.
Now you can copy your "system" partition to "system.img" with the following command:
Code:
dd if=/dev/block/mmcblk0 bs=8192 skip=55296 count=529920 of=/data/media/0/system.img
Replace the values with the ones you calculated for your model!
Now you could copy the "system.img" to your Linux and root it or do everything else you want.
Important: Do NOT delete the original "system.img" from your internal storage as long as you are not 100% sure your G4 is stable.
If your modifications don't work, you can copy back the original "system" partition (with "dd").
To copy the modified "system_changed.img" back to the "system" partition use the following command:
Code:
dd if=/data/media/0/system_changed.img bs=8192 seek=55296 count=529920 of=/dev/block/mmcblk0
Replace the values with the ones you calculated for your model!
Important: Be sure to use "skip" when reading and "seek" when writing.
The "dd" command should take about a minute.
Did the instructions help you?
Please give a "Thanks!"
Thank you

Hi,
thanks for this great post.
I just have one question. With your formulas and using 8K block size, I get a floating point number as result. So I used a block size of 4K instead, and I get an even number. This seems better to me so I went with it, as I believe smaller block sizes are always ok?
I'm just wondering one thing which seems not right to me. My system partition is reported to be 2.5GB:
Partition number (1-42): 39
Partition GUID code: EBD0A0A2-B9E5-4433-87C0-68B6B72699C7 (Microsoft basic data)
Partition unique GUID: A8725BAA-9E45-B2F8-8FA3-8C972F60F0CF
First sector: 836608 (at 408.5 MiB)
Last sector: 6074573 (at 2.9 GiB)
Partition size: 5237966 sectors (2.5 GiB)
Attribute flags: 1000000000000000
Partition name: 'system'
So with the formulas:
FACTOR 512 / 4096 = 0.125
skip and seek: "First sector" * "Logical sector size" / bs
836608 *FACTOR = 104576
count: "Partition size" * "Logical sector size" / bs
8478720 * FACTOR = 1059840
If I now run the dd command:
dd if=/dev/block/mmcblk0 bs=4096 skip=104576 count=1059840 of=/storage/external_SD/system.img
I get a file system.img which is 4096 MB. Should it not be 2.5GB as my original system partition?
If I use bs=512 (the default) and type
dd if=/dev/block/mmcblk0 bs=512 skip=836608 count=8478720 of=/storage/external_SD/system.img
I get a system.img of the right size (bit over 2.5GB).
I think the block size to use for "skip" is to be specified with the option ibs=XXX, not bs=XXX which only applies to "count" (according to man dd). I tried the ibs option, but the command then just doesn't work on Send_Command.exe. It doesn't even print an error but simply returns immediately.
Cheers
Jen

Hi,
which phone do you have?
Your calculation seems wrong. It's ok to use BS with 4k. I could be a bit slower then 8k, but that doesn't matter.
BUT: Look at your "count" value. Your partition size is 5237966. You used 8478720 (the value from my G4(H815EU) example). Thats wrong!!!
How to calculate with 1k and your values:
bs=1024
skip=836608*512/1024=418304
count=5237966*512/1024=2618983
Please check my calulation!!!
It's interesting, that the Send_Command shell has access to your external sd card...
I think the block size to use for "skip" is to be specified with the option ibs=XXX, not bs=XXX which only applies to "count" (according to man dd).

No. "bs" is the right parameter.
If you use "bs" it sets "ibs" and "obs" to the value of "bs".
Just do "dd --help" on a linux system for more details.

Hi Dominik,
oh my, how embarrassing I actually did take the wrong value from the example you posted. I used my value (the 5237966) for calculating the parameters with bs=8K, and got a floating value, so tried 4K instead... and the wrong value must have snug in. Oups.
I also get floating value on 4K now that you've pointed my mistake out:
5237966 * 512/4096= 654745.75
If I rounded this up, would this not mean that I copy a tiny bit of the next partition on the image? And if I then use the image to restore, would I not run the risk to damage something in the following partition?
Anyway, it's not a huge drama as I can just use bs=512 and it works.
Yes I have access to the SD card, the image also has copied there successfully. I was also surprised because I read in the forums that it's not possible.
I found it out with the "df" command, as the SD was listed there. I needed to use it because there's no room on my internal storage (it's a ridiculous 8GB on the LG H735) to store the image there.
My system partition is only 2.5GB so I don't think I have to reformat, but you are right it would be better to use ext4.

Ok
I removed my information about formatting the sd card.
You dont't have to format it. FAT32 is ok.
So you can use your sd card on systems which don't support ext4 too.

I have the LG G4S (H735). It's unusable without rooting as it only has 8GB internal memory. That's why I'm trying to root it now.

My sister asked me to root her phone. It seems more complicated than anything I did in the past (HTC Wildfire, Galaxy Core Plus, Xperia M4A).
I tried this tutorial and it kinda worked, but I can't mount image I got, so it's useless (image, not tutorial!).
Phone is LG-H736 (Beat). I got this result in gdisk:
Code:
Partition number (1-42): 39
Partition GUID code: EBD0A0A2-B9E5-4433-87C0-68B6B72699C7 (Microsoft basic data)
Partition unique GUID: A9520AE6-ABC6-F107-E8FE-B37C4C30CB77
First sector: 836608 (at 408.5 MiB)
Last sector: 6074573 (at 2.9 GiB)
Partition size: 5237966 sectors (2.5 GiB)
Attribute flags: 1000000000000000
Partition name: 'system'
The 8K bs gave me floating point result, so I used 0,5K.
So the dd command were:
Code:
dd if=/dev/block/mmcblk0 bs=512 skip=836608 count=5237966 of=/storage/external_SD/system.img
BTW, I had access to SDCard and I didn't need to open ports...
EDIT: I got the system.img. The problem was I haven't got enough space on SD card.
But now I bricked it...

ADB and FASTBOOT Modes
The Vernee Apollo's bootloader supports Fastboot. The Recovery mode supports the Android Debugging Bridge (ADB) . To access, perform the button sequence below. A menu will appear allowing you to cycle through option to either boot into the recovery partitio,n or to start the Fastboot service.
ADB service is also available also within the Android desktop if you enable USB Debugging in the revealed developers settings menu. You will most likely need to accept a signed key issued from the managing computer for the service to communicate!
Accessing Bootloader Menu
Buttons: [Top-Volume] + [Power-Button] for 8 Seconds.
When the phone is shutdown, hold both buttons at same time from for 8 seconds. The Bootloader menu will appear and then release buttons.
Using Bootloader Menu
Button: [Top-Volume] = Cycle selection.
Button: [Bottom-Volume] = Choose selected item.
With the high screen resolution it maybe hard to see the text-options. There should be three;
1. Recovery, (Boot into Recovery partition with ADB.)
2. Fastboot, (Start Fastboot server.)
3. Normal. (Proceed to boot normally.)
Using Recovery Mode and Menu
When you boot the Recovery partition you will be meet with a failed Android icon on the stock Vernee release rom. ADB will be accessible from here. Note: The Recover menu will cause the ADB server to fail. If you want to display the recovery menu options then perform the following during the failed Android icon screen.
Buttons: [Top-Volume] + [Power-Button] pulsing till the menu appears.
Fastboot
If you plan to develop on your Apollo or to install future community roms then it's advisable to unlock your storage partitions. Unlocking will allow you to change partitions but doing so will void software warranty clauses, and in the process scrub all your personal data from the phone so it's best to do it before installing personal content.
To unlock the phone issue the following command through Fastboot. You will be asked to confirm.
Code:
fastboot oem unlock
Engineering Mode
Enter the following phone number in Android desktop
Code:
Dial *#*#3646633#*#*
Phone Test Options
Alternatively there is a phone test mode available at low level with less options. Whilst the phone is shutdown, press the following.
Buttons: [Bottom-Volume] + [Power-Button] for 8 Seconds.
A test menu will appear and is in simplified Chinese.
SIMS
If your phone is not receiving data over 4G or 3G, Google on another computer "apn" "YOURMOBILEPHONEPROVIDER" "YOURNATION". Example;
Code:
"apn" "vodafone" "uk"
You should find links to technical settings for your data provider's access. Then enter them in by navigating to;
Settings>More>Mobile network settings>Access point names>CLICK-YOUR-LOCKED-ON-PROVIDER>THEN-CONFIRM-SETTINGS
USB
Device USB Coding
Code:
System Mode:

ADB Mode:
ID 0e8d:2008 MediaTek Inc.
Fastboot Mode
ID 0bb4:0c01 HTC (High Tech Computer Corp.) Dream / ADP1 / G1 / Magic / Tattoo
Microsoft Windows VCOM Drivers
On Microsoft systems you will need to have drivers installed so as to communicate with the Mediatek phone.
MediaTek DA USB VCOM (Android) Driver 3.0.1504.0 for Windows 7/Windows 8.1
MediaTek DA USB VCOM (Android) Driver 3.0.1504.0 for Windows 10
UART Ability?
I haven't opened the phone yet but if anyone does please capture images of the circuit board. If there are UART pins on the board it may have a root shell piped to the interface. A UART (universal asynchronous receiver/transmitter) in this sense is a device that couples serial communications port to USB to run a terminal over.

Flashing Partitions
There are three main ways to flash;
1. using "Smart Phone Flash Tool",
2. Fastboot flash command,
3. via internal software like a root bash shell or routine from recovery.

Modifying Partitions
Modify partitions often means Users hacking the commercial roms and that means extracting out the important files to work with. The most important blocks are the system-partition which holds the operating system, then the recovery-partition which pole vaults Users with low level tools and abilities, like startup phone root powers. Noting many modern phone root modes, deploy on the recovery-partition rather than modify the system-partition, so as to retain full compatibility and retention of abilities, when conducting "Over the Air" / OTA updates from the manufacturer.
There are two popular platforms to hack on. 1. on native Linux including the phone itself, and 2. on a Microsoft Windows platform with Linux style utilities.
To ready a partition, to then modify it, and to then save it for flashing has many steps. One should obtain the manufacturer's rom or OTA update, to seek out the latest images and files to utilise.
In this example of hacking an official rom, we will be using "full_k15ta_a-ota-1484567521.zip". Utility executables are readily available in repositories related to your Linux distribution, like AUR on Archlinux.

2.) the images we are looking for are either the system-partition or the recovery-partition to modify. In this case there is only the system and it's held in the file "system.new.dat", a 1.6 gigabyte file. We know from the partition tables above that the system-partition is 2.6GB wide, so this image is either compressed or short. Most partitions deployed on Android for updating are compressed in what's called a sparse format.
We need to uncompress any sparse file before we can work with it or mount it, but the issue in this case is the image is also in "dat" structure, which means we need to unsparse using structured data held in "system.transfer.list". Here we use "sdat2img" executable to create the file "system_fullsize.img";
Code:
sdat2img system.transfer.list system.new.dat system_fullsize.img
Alternatively if the file was not a dat format, we could simply unsparse using;
Code:
simg2img system.img system_fullsize.img
3.) Now that we have the full image we can mount it as a file-system to tinker with it. Example of making a mount point and mounting it;
Code:
sudo mkdir /system
sudo mount -t ext4 -o loop ./system_fullsize.img /system/
You can now modify the image simply by changing the files in the directory mounted on. After changes you can save out and attempting to flash it back to the phone for your custom system.
Linux - CAPTURING THE MOUNT BACK TO AN IMAGE FILE
1.) After we have modified the mounted system-partition we need to save it back out for flashing if you want to see your changes live on the phone.
Labelling (If desired). We can name the mount to enforce block-labels. In this case the loop device was "loop0" used to mount the image. (Check which loop-device was used when performing this. eg: lsblk) Here we are going to label it "system"..
Code:
e2label /dev/loop0 system
It maybe important to set the partition UUID the same as the manufacturer uses so the the mounting process finds the correct partition to mount at boot. We know the system partitions UUID from the above discovery details;
Code:
UUID="da594c53-9beb-f85c-85c5-cedf76546f7a"
We can set the mounted image's UUID to suit the original before creating a new;
Code:
sudo tune2fs /dev/loop0 -U da594c53-9beb-f85c-85c5-cedf76546f7a
Here we capture out the device to an "ext4" format file-system image. The length option, being 2684354560 bytes. Labelling option "-a" with name "system".
Code:
sudo make_ext4fs -s -l 2684354560 -a system system_modded.img /system/
2.) To flash your image, Android's recent "fastboot" utility will allow for unsparse and sparsed images to be flashed. I have broken down the fastboot process into each step.
CAUTION: fastboot writes over your phone's partition blocks. If you are not skilled in this area of computing them research "fastboot" before use.
Note: current I have not found out why this process is incompatible with Vernee Apollo. The images I write back are not operational even though they flash properly. My hunch is that I may need to enforce an ISO/image UUID the same as the manufacturers, but I haven't tested this yet.
Code:
fastboot -w
fastboot format system
fastboot flash system ./system_modded.img
If we want to sparse the file before flashing;
Code:
img2simg system_modded.img system_modded_sparse.img
If we want to create a sparse dat structured image;
Code:
img2sdat ./system_modded.img
Linux - ACCESSING RECOVER IMAGE TO MODIFY
An Android recovery image is really three items in one image. There is a compressed kernel (zImage) used to run a recovery system, a ramdisk (initrd.img), and configuration file. The ramdisk "initrd.img" holds the operating system files used by the recovery kernel. Note the bootimage partition/image is a similar structure to a recovery-image.
If you need a similar development community then the Xiaomi Redmi Pro is a similar phone due to its Mediatek Helio x25 but it uses a different cameras, screen and sensors. Modifying and tweaking settings in their recovery images can work on your Vernee Apollo X25.
To extract the sub held files (bootimg.cfg, zImage, initrd.img);
Code:
abootimg -x recovery.img
To unpack a ramdisk "initrd.img";
Code:
mkdir initrd
cd initrd
sudo zcat ../initrd.img | cpio -idmv
To pack files whilst in your ramdisk directory ''/initrd";
Code:
find . | cpio -o -H newc | gzip > ../newramdisk.cpio.gz
To pack back up components into a recovery rom;
Code:
abootimg --create recovery_new.img -f bootimg.cfg -k zImage -r initrd.img
Alternatively;
Code:
mkbootimg --cmdline 'no_console_suspend=1 console=null' --kernel ./zImage --ramdisk ./newramdisk.cpio.gz -o recovery_new.img

Hardware
Protective Covers
Silicone and more rigid covers are becoming available for the Vernee Apollo. Make sure you don't get a Lite version as it wont fit.
Those looking for more range and are willing to mod, the Lenovo K5 Note is very similar in dimensions to the Apollo X25, but the headphone jack, volume and power buttons are slightly off. Modding a K5 Note case will require cutting holes for the headphone jack, buttons, speaker holes, and possibly for the flash. Clear covers will allow the flash to work. Make sure the camera and finger scanner is a complete open section on any K5 cover!

I left it up to you to post. I hope people comment on what they think. I'm working on my own images so I can't install others at the moment to give an opinion. Readers please note I can't verify the security on this share. Do not take any compromising actions.
I'm super busy so not sure when I will have my own solutions.

How I wish I had more knowledge. This piece of Hw (Raw Hw?) has a lot of potential, but lacks interest of any developer adapt/adopt it....
The conditions are there (lets hope the owners free the code, as they have done with its small brother), and let's hope there are enough and good drivers for the chosen Hw.
Just to encourage your efforts.
Regards

I agree
lots of good hardware and poor software...I hope in this community

At the moment I found these "bad" things about this phone:
1) you can't choose to view the battery percentage in the upper bar
2) you have to set the APN manually or you can't use internet
3) you can't turn volume up or down if the screen is switched off

I've kind of hit a wall with modding the system image to root it. The system images I produce are just not compatible with flashing. They flash but no desktop runs on the phone. Tried both sparse and raws. and I've got the partition size correct. Mount point is set properly to "system" and they're ext4 images.
I'm building Chainfire's version of ext4_utils, specifically the make_ext4fs util. If that doesn't work then I'll build Google's version. Long process as you need SELinux headers which takes ages to install. There maybe a bug in older versions that's causing the trouble. Other thoughts, there maybe a different padding method or bit plane for storing file system nodes. I may need SELinux builds of executables just to get the job done as I did notice in a hex.diff that the original image has SELinux stamps in it. I need more investigation to know why that's so.
It would be nice if Cleopatra Bianchi chimed in if She knows the issue or has even been down this road before, so to speak.

Hi, E8
Do not know even if this could be valuable, but the sources of the lite version are there. I suppose they are taking the same engineering approaches with the big brother... or not...
but would check

You can easily restore the phone using the official zip rom. Place it on a micro sdcard and install via the Bootloader menu. Instructions are on the forst comment on how to get to the bootloader menu and then recovery. If you're destroyed your recovery partition but still have fastboot access then you can use the system image within the official rom to flash the system partition with a bit of modifications.
I've been super busy so I haven't had the time to work on my own version of the TWRP Recovery.

How can I find the drivers ? When I google search I only find the one for Apollo lite

Do not believe you can "unlock" US bands, as they differ from EU/ASIA system.
Anyway, trying is (almost) free. The worst thing can happen is a brick

[REQUEST] ZS570KL (64G) partition dump / aboot

I would appreciate if someone would do the following in a rooted adb shell session:
1: print the list of partitions tables via busybox parted applet (& paste it here)
Do so in both sectors & bytes by selecting "unit s" & "unit B" in parted.
2: dump (via dd) & upload all partitions to google drive.
system, boot, cache & userdata are not needed.
I'm specifically looking for the aboot/emmc_appsboot partition

How To Guide How to backup your partitions with command line (requires root)

How to backup partition images with dd on the command line (root required)​
We don't currently have a working custom recovery for the Xperia 10 III, but if you have root there's a simple method to dump partition images.
This is a very good idea and you should do it at least once, especially if you like to mess around the device a lot.
You won't be able to do this before you root, so by the time you do some partitions will not be stock anymore. Use XperiFirm instead to get the clean stock images.
Special partitions:​
The userdata partition holds all your personal files and system settings. It's huge (about 105 GB) and obviously you can't dump it into itself. You can dump it on an SD card if it's 128+ GB.
The super partition is a physical partition that contains several logical partitions (including system and vendor) That's why you won't find those in the partition list. This is done on Android 10+ devices to allow those logical partitions to be resized or rearranged as needed. You don't need to split out the internal logical partitions, you can flash back the entire super partition. The stock firmware also comes with a super image, not individual logical partitions.
Using a helper script:​There's a Magisk module called Backup (by Draco) which gives you a command line shell script you can use if you prefer. It mostly does the same things I described above. The script is here if anybody wants to just grab it directly.
On the plus side, the script knows to dump only the active A/B image (which is the one that interests you most). On the flip side, it doesn't have a feature to skip userdata.
So here is a shell command that will use the backup script to dump all partitions, but only those matching your device's active A/B slot, and skips userdata:
Code:
backup $(ls /dev/block/bootdevice/by-name/ | grep -v userdata | sed 's/_[ab]$//')
And here's one that also skips super:
Code:
backup $(ls /dev/block/bootdevice/by-name/ | grep -v userdata | grep -v super | sed 's/_[ab]$//')
How to dump partitions manually:​If you can't/won't use the helper script you can do it by hand. All the following commands need root:
Find the names of all the partitions:
Code:
ls /dev/block/bootdevice/by-name/
Dump one specific partition identified by NAME:
Code:
dd if=/dev/block/bootdevice/by-name/NAME of=NAME.img
Dump all partitions except userdata:
Code:
ls /dev/block/bootdevice/by-name/ | grep -v userdata | while read NAME; do echo dd if=/dev/block/bootdevice/by-name/${NAME} of=${NAME}.img; done
Find the active slot:
Code:
getprop ro.boot.slot_suffix
Get checksums for all the images after the dump:
Code:
md5sum *.img
Confused about _a and _b partitions?​You should read about A/B Seamless Updates.
Long story short, some partitions have two copies eg. boot_a and boot_b. When you boot up the device you use the partitions in one slot (eg. the _a partitions). When an OTA update is being downloaded, it writes into the partitions for the other slot (eg. the _b partitions). Your phone can stay in use while this happens. If the OTA fails nothing is broken, you just keep using the good slot partitions. After the OTA is successful you switch to the other slot and also have the previous version in the other slot in case you need to switch back.
This means that some of the _a and _b images for the same partition can be different for you! So it's strongly recommended to do the checksums, and also to find out which is your active slot, so you know which partitions you're using right now.

I used a 128 GB card to take a backup of userdata. The backup script had some trouble with the backup location being on the storage card for some reason and I didn't have time to figure it out, but the dd command I gave above worked fine.
Code:
# time dd if=/dev/block/bootdevice/by-name/userdata of=userdata.img
112111374336 bytes (104 G) copied, 2342.274225 s, 46 M/s
39m02.31s real 1m11.78s user 14m44.72s system
Code:
# adb pull /storage/1234-ABCD/backup/userdata.img ./
/storage/1234-ABCD/backup/userdata.img: 1 file pulled, 0 skipped.
87.2 MB/s (112111374336 bytes in 1225.663s)
So that's 104 GB that took 39 minutes to be written to a new Samsung Evo U3/V30 microSDXC (46 MB/sec real write speed) and 20 minutes to be read to the PC (Samsung Evo M.2) with adb pull over USB (87 MB/sec read speed). Just so you know what you're in for.

I was looking into whether I could speed up the process of taking userdata snapshots by dumping the partition directly to the PC, but you need to be root to access the device block. The stock ROM doesn't allow the command adb root, but I found this blog post which made me realize you can run a su -c command that asks dd to write to stdout and just pipe the output to a file. The post author has also made this helpful Python script which lets you do pulls and pushes with root-only files.
If you want to run the command directly (I've only tested on Linux, no idea if it works on PowerShell but it might):
Code:
# adb shell "su -c" "dd if=/dev/block/bootdevice/by-name/userdata" > userdata.img
If you want to use the Python script:
Code:
# adb-root.py pull /dev/block/bootdevice/by-name/userdata userdata.img
Using the same fast SSD on the PC side as above, I now get:
Code:
218967528+0 records in
218967528+0 records out
112111374336 bytes (104 G) copied, 1077.681097 s, 99 M/s
real 17m57.910s
So that's roughly 15 minutes compared to 1 hour total with the previous method and you don't need to have a 128 GB SD card anymore.

Are you able to switch to a different backup location? Say a USB OTG if possible.

With dd yes, simply move to the directory you want before you call dd.
The backup script is bugged and seems to ignore the -d parameter for the backup location so it always uses /sdcard/backup. (I think it might be expecting a different version of getopts...) Normally I would say to try creating a symlink from /sdcard/backup to the OTG storage but the ln utility is also behaving strangely and I can't make any symlinks (even with root).

Ok I'll give it a try and see what happens. Thanks for your help.

Hi, I'm used to TWRP backups, so I don't really understand this tool. I've backedup everything except the massive userdata partition. If needed, how would I restore this? Is the userdata partition required when I have all the others?
Thanks!

This is basically the same thing that TWRP does, dd is a command line Linux tool that makes a "raw" copy of a partition.
Restoration is a bit more tricky. In theory you can simply dump the raw backup copy over the partition. The problem is that it's not ok to do it while the system is running. Typically it's done by booting into recovery (TWRP) and overwriting the partition from there.
Another method for restore is to use fastboot, which is an alternative tool you can boot into that only does one thing, write partitions. But fastboot is typically locked by the vendor to only write signed images, so it can only be used to write official release ROMs.
There are some limited uses for fastboot, such as overwriting the boot partition, which is not checked for signature anymore once you've unlocked the bootloader. So if you want to experiment with unofficial kernels and mess something up you can always restore a good boot partition with fastboot.
TLDR: for the time being until we get a working TWRP recovery the most you can do is take backups, but not restore them.

I don't know how I ended up but making a backup you can't restore is completely pointless.

No, it's not. All your data is in there. You can mount your backup on a linux computer and pull out apks as well as app data. You can then restore these folder by folder with adb and a root shell on your phone.
That beeing said, does anyone know a proper backup software like Titanium Backup for Android 11 and above? Sometimes I read recommendations, but looking at the ratings it seems that no software manages to achieve the same level of comfort and control. Also they all seem to suffer from the same limitations.
Let's be honest: Google wants to make your life hard, so they can lock you in.

@xperinaut
I'm using Titanium on Android 11. Is it not working for you?
