Dump GearBest MIUI ROM before installing official MIUI?

Hi,
is it possible to dump the original ROM which is installed on GearBest Phones before putting TWRP and MIUI 8 via EDL on the Mi Max? I think if the phone is faulty you have a chance to remain warranty if you can flash the GB ROM back.
Thanks

I don't think there is any easy way to dump the content of all partitions. Fastboot does not provide the way, maybe some other tool?

You can use dd command like this on rooted device:
Code:
su
dd if=/dev/block/platform/soc.0/7824900.sdhci/by-name/system of=/sdcard/system.img
All Mi Max partitions:
Code:
# ls -l /dev/block/platform/soc.0/7824900.sdhci/by-name

Nice
Are the Block ids for/from Hydrogen or Helium?
But how to root a Stock device? I Mean i could Flash twrp on a locked device via edl and maybe put supersu via twrp on it but then i don't have the stock recovery because I overwrited it with TWRP.

Both hydrogen and helium have same block ids but if you use .../by-name/... it doesn't matter...
China dev MIUI has root but you want to backup the original state so that is not a option...
The only option is to flash TWRP, mount all partitions posible and do dd command from TWRP to preserve /system original no root state and forget about stock recovery which btw is just a picture and nothing else...
There is even a TWRP mod that enables all those partitions in mount screen...

Why do dd commands if he can just do full nandroid backup of all partitions, if he flashes twrp? That way he can restore it if needed and eventually flash stock recovery and be done Whit it!

Aren't the partitions encrypted? I'm not sure but I think a backup with TWRP didn't work because of encrypted partitions. At least data.
Stock recovery is a picture - I know - but it's about to send the phone in case of a warranty back and therefore it should be 100% stock. But I think this won't work...

If you can backup all partitions you need with TWRP then yeah...
But I don't think you can...

Please help its a request.

Hi friends,
I lost imei on my moto g5 because I had installed oreo 8.1 rome on it.
while I was trying to fix the imei on its stock rom that I had flash after flashing oreo 8.1.
I thought dhob -> /dev/block/mmcblk0p20
and hob -> /dev/block/mmcblk0p19 are the two files that contain all the data of IMEI and network.
so I searched on web and foun these two files of some other moto device. I went ahead and flashed these two files onto my file. which actually didn't resolve the issue. but gave me some more issue. now after doing this fingerprint stoped working.
Then I went ahead and ran fastboot clear all command from the cmd in fast boot thinking that it might remove these two file that I have flashed. but by doing that I lost wifi as well.
now the situation is this that there is no imei on my moto g5, wifi is not working, finger print senser is not working.
so finally i relocked the boot loader and thought maybe I will take it to service center and they will fix it. but they found that it is out of warranty and asked for money which is 80% cost of the mobile phone. actually they are telling me to replace the mother board.
I know there should be someone on XDA who can actually help me. I understand I have messed it real bad. But I really need this phone.
so this is my final request to all XDA members and all DEV's out there please help me.
According to my knowledge I will need the back up of some files from a working moto G5 cedric, That I can flash to my moto g5 cedric:
here are the files that I need:
aboot -> /dev/block/mmcblk0p4
abootBackup -> /dev/block/mmcblk0p11
dhob -> /dev/block/mmcblk0p20
fsc -> /dev/block/mmcblk0p22
fsg -> /dev/block/mmcblk0p21
hob -> /dev/block/mmcblk0p19
misc -> /dev/block/mmcblk0p30
modem -> /dev/block/mmcblk0p1
modemst1 -> /dev/block/mmcblk0p17
modemst2 -> /dev/block/mmcblk0p18
persist -> /dev/block/mmcblk0p29
rpm -> /dev/block/mmcblk0p5
Here is the script to take the back up:
This one is for about. please make the changes accordingly to take the backup for others:
adb shell su -c "dd if=/dev/block/mmcblk0p4 of=/sdcard/mmcblk0p4.img"
you will have to use this script on fastboot in cmd. while your phone is turned on and first you will have to give fastboot root access.
Again This is a request someone please please please help.....:crying::crying::crying:
If you need any help in taking backup please reply I will surely help with that.
Requirements:
- Device has to be rooted, with USB debugging enabled.
- Motorola fastboot (see attachment).
- ADB installed, minimal or the full ADK.
You can search the forum to find how to meet these requirements or for the terms described in this post beginning here:

So i have already do a backup of all partition (to .bin files) but as it said in the folliwing topic,
https://forum.xda-developers.com/showthread.php?t=2450045
If the partition is formatted as ext3/4 then the dumped partition will have .img as an extension.
Other partition dumps have different extensions; examples:
radio.bin
param.lfs
Sbl.bin
zImage (without extension)
Click to expand...

What's possible to launch for zImage (without extension)? The following command ?
Code:
dd if=/dev/block/platform/msm_sdcc.1/by-name/mfg of=mfg.zImage
or just .img extension file is okey for reflashing ?
Code:
dd if=/dev/block/platform/msm_sdcc.1/by-name/mfg of=mfg.zImage
A script already exist to backup all partition ? an example : https://forum.xda-developers.com/showthread.php?t=2073775

Moroever, can we create .tar.md5 for flashing BL, AP, CSC, ?
The following old code, we can create .tar.md5 files with X part.
A template exist for htc one m8?

Not quite the same. There are texts that say the partition name in them.
No idea if a copy from a different device works at all.
That is, what they are used for... these protects...
Have you tried LGUP using refurbish mode?
It should do some wiping before writing.
Or LGBridge?
>LGlaf
Haven't been able to write a partition with that, in windows.
It "writes", that is, it takes its time but it doesn't stick...
I could write into some partitions in terminal mode,
but not into boot and recovery etc.
Now, with root writing into those partitions is possible but useless.
Corrupted, not trusted, whatever errors if them are modified...
Bootloader...

Question Implications of having both A/B slots and recovery partitions

I'm learning about A/B slots, and i have always seen it said that the recovery partitions were removed. Ex: "But the A/B approach gets rid of the separate recovery partition and integrates it into the boot partition."
OrangeFox gave me a warning that the phone has A/B slots but also recovery partitions.
I checked and can confirm:
ginna:/ # ls -la /dev/block/by-name/recovery*
lrwxrwxrwx 1 root root 21 1970-07-23 01:57 /dev/block/by-name/recovery_a -> /dev/block/mmcblk0p45
lrwxrwxrwx 1 root root 21 1970-07-23 01:57 /dev/block/by-name/recovery_b -> /dev/block/mmcblk0p46
1) How common is this?
2) In this case i guess it means the XT2052 cant lose it's recovery when flashing a boot image and boot doesn't need to be patched with a recovery beforehand, correct?
3) Anything else should i be aware of when reading discussions about devices without separate recovery partitions? Like some common steps that should NOT be done in my situation?
