I accidentally flashed persist partition on another phone.
As a result, all sensors are not working now.
I haven't backed up that partition.???
Therefore i would like to ask someone to backup persist partition and share the image file with me.

But I don't know how to use the dd command.
Can I use fastboot command to flash?

I don't know exactly how, but you can use dd command to back up.
I don't know the exact file path.

Thank you very much!
The img.persist file was renamed to Persist.img, and the bootloader flash using the fastboot command, and the sensor returned to normal.

I just had an idea. What if someone roots a system.img by extracting it from a kdz and then mounting it in linux copying the root files setting the permissions and then flashing that with download mode? A simple
Code:
dd if=/data/local/tmp/system.img of=/dev/block/platform/??????/by-name/system
should do the trick to flash the system.img file replacing the ?????? with the correct directory.
Just a thought.
Wouldn't you have to have read/write access in order to push the system.img?
Impossible,without root.

Already tried something similar. Requires root unless you're one of the lucky few who have such advanced knowledge of hacking bootloaders/exploits....which I unfortunately am not. LOL

Yes, look in the developer section.
It is possible to dd to partitions using download mode. The only real problem is that the root method would be huge having to include a system.img.

Additionally, you'd need a separate one for every carrier/variant.
I guess if it worked though, who cares how many we need or how big they are. Except with dd, one typo and you've got yourself a brick.

Though...wouldn't it still be able to get into download mode? I could be wrong, but that's not on the system partition from my understanding.
I'm on linux and am familiar with dd (I'm a distro-hopper and have no optical drive, so everything gets dd'ed onto usb drive).
Wouldn't we have to specify a block size on that? I know at least on linux distro, if block size isn't specified, I end up in non-boot.

Actually you are correct. The laf partition is the download mode. Flashing recovery is where we have to worry about losing download mode. (I never understood why, but at least with the G2 download mode broke when flashing custom recovery without a certain patch)

How can you confirm being able to dd to partitions using download mode? In download mode isn't the dd running from /system/bin that is mounted as ro. How could you replace /system while it is mounted and running dd from it?

linux loads commands that you are in the process of running into ram. You can even delete a file that you are running and still be able to use it until you close it. Once you close it is when the problem would occur but by that time you would already have the new file in place. Also do NOT run a
Code:
dd if=/dev/zero of=/dev/block/platform/??????/by-name/system
just skip that step otherwise you would lose the ability to dd.
Go directly for a
Code:
dd if=/data/local/tmp/system.img of=/dev/block/platform/??????/by-name/system
also to get a system.img instead of extracting from a kdz you could run
Code:
dd if=/dev/block/platform/??????/by-name/system of=/data/local/tmp/system.img

Update please if you have root, go to adb then type adb shell and then su. after that just run this command dd if=/dev/block/mmcblk0p7 of=/storage/sdcard1/recovery.img, if you want it to go somewhere else then just change the part that says storage/sdcard1(for example if you want it to go to the device storage then just remove the 1) the recovery image should then be on your sd card. please then attach or send the recovery image to me.

hey buddy, i was searching for info regarding this persist partition and i stumbled upon your post. Actually, I have a Lemax 2 and there is this camera focusing issue with nougat ROMs, and somebody was suggesting that it could be some issue with the persist partition.
So i was thinking of trying to modify or edit this persist partition.
So, can you just mention what you have done and what the above image was for?

You could try this not sure if it work haven't tried yet use terminal emulator
Run this first and it will list your img you want
ls -al /dev/block/platform/soc/1da4000.usfhc/by-name
dd if=/dev/block/platform/soc/1da4000.ufshc/by-name (the img you want) of=/sdcard/ (your img)
You can use this command to dump any partition updated command

If you flash the stock restore from invisiblek yes the a and b img should be the same, I think not positive not much knowledge on a and b partitions. But what I got from invisiblek's post is that is correct.

Hey guys as you know that we are able to get back volte successfully in Moto g5 plus by restoring PERSIST BACKUP.
So I think MAYBE persist partition got corrupted during flashing back stock.
But that backup is from MOTO G4 PLUS ,and some user facing a problem that whenever they reboot volte and imei again gone,and Everytime they have to restore efs (maybe because of that persist partition)so I am requesting you ,can someone please pull out persist backup of STOCK MOTO G5 PLUS WITH WORKING VOLTE (OR G5 PLUS WHICH IS NOT BRICKED YET).
I AM ATTACHING A TWRP FOR TAKING BACKUP WHICH IS MADE BY DEVELOPER.
SO YOU HAVE TO JUST GO IN TO BACKUP AND TAKE BACKUP OF PERSIST PARTITION
You can download twrp from below link.

I am not responsible for any brick/damage caused during you taking backu
Alright, so I got a Persist backup using the partition backup & restore app. I don't use VoLTE, but my IMEI hasn't become zero. I'm on Oreo. It's saved as a .img file. If this is helpful I'll upload the file. @akshu2697

With a lot of research, I was able to dump the persist partition using adb. My dump will do no good, as I have only been able to get persist back by OP's method. We need someone to dump who has not flashed an oreo rom. Ok, that being said, here is how.
Make sure your phone is rooted.
Make sure usb debugging is enabled.
Boot phone into recovery.
Open adb with phone connected to pc.
Code:
adb devices
You should see your device listed.
Code:
adb shell
You should get ~# and something like a backward arrow [6N. That was mine yours may differ. If you have ~$ instead of ~# you are not rooted properly. If you used magisk you may have to add the sudo module.
Code:
ls -al /dev/block/platform/soc/7824900.sdhci/by-name
This will give you a list of all partitions. Look through them and find one described as persist. Mine was this:
Code:
lrwxrwxrwx 1 root root 21 Jan 1970 persist -> /dev/block/mmcblk0p30
We are interested in the address /dev/block/mmcblk0p30.
We need to type in
Code:
dd if=/yourMountingPoint of=/yourDestination/partitionType
where /yourMounting point is the persist address, if like mine /dev/block/mmcblk0p30. /your destination will be where you want to save it, and partition type should be persist.img.
My command was this
Code:
dd if=/dev/block/mmcblk0p30 of=/external_sd/persist.img
This will give us a proper persist .img file.
Here it is.
I clean flash stock rom (potter_NPNS25.137-93-4) before getting the persist file, was on crDroid 7.1 before. I don't know if volte is working because we don't have it on my country, but I never flashed Oreo before and never lost imei or 4g/lte, so it should be fine.
Hope it helps us and use at your own risk.

Aren't you the OP of this? I thought you needed a way to dump the original partitions, and I provided the method with step by step to do so. I've never coded for android systems, but I'm very familiar with close cousin linux, so I suppose I could investigate and learn. However I would think whomever developed the G4 plus method could use the above dump for our phone. I guess I assumed it was you who discovered this method. I'll dig into it further when I get some time, but getting the clean persist dump was what was asked to do.
I was able to write the above persist.img file by:
1. transfer persist.img to my external_sd
2. booting into twrp
3. opening terminal
4. entering
Code:
dd if=/external_sd/persist.img of=/dev/block/mmcblk0p30
However, this placed my EMEI to 0, and I had to restore my saved efs with moto g4 + persist to get signal back. But remember, I had problem with efs every time I reboot, so my case may not be typical of those of you whose moto g4+ persist was working fine for. I would be curious if N1vBruno's persist was at the same address as mine, namely
Code:
/dev/block/mmcblk0p30
Guys who have restored their VoLTE, does your IMEI match the one that came with your phone or has it changed to something else?
I'm just being curious as I thought using someone else's persist backup would restore his IMEI to your phone, or was it efs?
Please correct me if I'm wrong.
