[Request] HAM2 Stock OEMInfo File - Huawei Ascend Mate 2

Hello,
I've been trying to return my CC HAM2 to Huawei Stock HAM2 and according to one user, I need two files; oeminfo partition file and custom.bin from someone with the Huawei Stock HAM2 (not the CC variant) that is rooted. Here are the steps you can use to get these files:
1. oeminfo partition
Connect your device to PC and backup your oeminfo partition with these commands:
Code:
Code:
adb shell su -c "dd if=/dev/block/platform/<device>/by-name/oeminfo of=/sdcard/oeminfo"
adb pull /sdcard/oeminfo oeminfo
adb rm -f /sdcard/oeminfo
Execute them from ADB folder. It's three commands, run them separately. Don't forget to replace <device> with your existing folder.
Now you should get oeminfo file in ADB folder. Check it, if OK, then save it somewhere else.
2. Custom.bin
This file can be located at: /data/custom.bin

I think the OEMInfo Partition (mmcblk0p8, size 67,108,864) contains IMEI and SN info, it is not worth the risk to mess up with them.

Thanks for your reply. I don't really know that much about the internal make up of android devices, so maybe that's why I asked requested that file. I was told by a user [Kostyan_nsk] in one of the threads I created asking how to flash the stock HAM2 OEM over the CC version and the guy said I need the OEMINFO file from someone with a stock phone (not CC). I really had no idea why but in his procedure, getting the OEMINFO file was essential to the process. Now, I wonder how I can get of the CC version !!!!

I was replacing whole partition from other device, but my IMEI and SN stayed the same. So it's not in there.
Well, may be in your device its size is 64MB if you are not confused blocks. In mine it's mmcblk0p9 and has 32MB size.

I always thought it was stored in the phone hardware.

Strange. There's no any personal information to be afraid to reveal.

Still kinds of worried because I have seen mixed answered about the OEMInfo partition has sensitive info or not.
My MT2L03 unlocked OEMInfo image:
ls -l : 67108864 Oct 9 00:45 mmcblk0p8.img
md5sum: d9c1a0287bb94b7b0d5d83e0________ mmcblk0p8.img
I have masked the last 8 digit of my md5, if anyone else can confirm the md5sum is same as mine, I will share the image.
Sorry if this looks too much. I just want to be super careful that my phone IMEI/SN will not got flashed to other phone, and maybe lots of phones if it got published.
This is the post that I got scared of:
http://www.modaco.com/topic/362644-is-there-a-way-to-copy-an-officially-unlocked-ics-bootloader/
"The only way to do what you are asking is to use the oeminfo partition from another phone that has unlocked bootloader, and that will make you lose your imei number after installing an update.app."
So, it is possible you may not see any problem right away after flashing, but only found your IMEI lost after an update which maybe months later.
So, anyone can check your vanilla MT2L03 md5sum of the mmcblk0p8.img, please confirm.

Well, and according to this post about successfull backup and restore of IMEI, it seems to be in 'nvme' partition.
And I was not lost my imei after flashing update.app with replaced from other device oeminfo partition.
I'm just curious where was it started from that imei is in oeminfo?
In addition: I have found Board ID, SN, MAC WLAN, MAC Bluetooth, Bootloader unlock code, but IMEI still not found.
I'm starting to think it's stored in hardware and cannot be changed. Seems like it was stored in partition in previous, early devices, but now it's not.

1. oeminfo partition
Connect your device to PC and backup your oeminfo partition with these commands:
Code:
Code:
adb shell su -c "dd if=/dev/block/platform/<device>/by-name/oeminfo of=/sdcard/oeminfo"
...

Code:
C:\Users\User>adb devices

minfo of=/sdcard/oeminfo"
/dev/block/platform/9cc1722xxxxx/by-name/oeminfo: cannot open for read: No such

I masked my serial number but that's what I get when I run that.

The by-device field is a folder name - not your serial number. Its one of the folders in /dev/block/platform/. For example, in my CC variant it is: msm_sdcc.1
It might be the same for your phone. In fact if you have root explorer or some other software just enter /dev/block/platform/<device>/by-name/ and you can copy the oeminfo file without the need for adb. Try it.

Used root explorer to copy the files and hashmyfiles to generate the md5:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Looks quite different.

By the way, I have found where IMEI is.
So now I can confidently declare that it's not in OEMInfo.

PHONE:
I have the stock carrier unlocked MT2-L03 from Amazon/Huawei.
SIZE:
12/30/2014 11:48 PM 67,108,864 oeminfo 1 File(s) 67,108,864 bytes
12/30/2014 11:48 PM 67,108,864 mmcblk0p8 1 File(s) 67,108,864 bytes
(64mb)
COMPARED:
I used UltraCompare Lite on the files in binary mode...they are exactly the same except for the names. The contents are identical.
MD5:
I'm not sure why they seemed different before. Maybe a copy error.

Thanks, actually, Today I tried to fetch the OEM info again, it changes, maybe because one is before update, the newer one is after, but still it is not matching with yours.

Anyway, read some where that the OEMInfo pretty much is a data storage partition, that it stores different regions/carrier info/settings of the phone. So, how many unique info is stored here, I am not sure, maybe IMEI is not here, but if other MT2L03 image is not same as mine, I am not comfortable to share mine. Sorry.

Well, if there is no full UPDATE.APP for MT2-L03, then the idea of replacing oeminfo is useless.

Yeah I'm not willing either if there is personal info there it's not good to clone that.
