Can you post the code to extract emmc image?? I have a Coolpad manufactured phone and it's in Qualcomm HS-USB QDloader mode.

I can get the emmc image from another fellow user. We've tried "dd if=/dev/block/mmcblk0 of=/sdcard/mmcblk0.img" however the output file size is as large as internal memory itself.

As I understand we just need a few initial hidden partitions in the image not the entire emmc image.

Kindly advise.

Thanks a BUNCH :good::good::good::good::good:. I have used the trick on a Coolpad manufactured device "Qiku Q Terra 808" which was hard bricked (Qualcomm HS-USB QDLoader mode) and the trick worked flawlessly.

Thanks for the tutorial I was able to revive my dead device. I had obtained the emmc image from a fellow user however the 200 mb emmc didn't work hence I requested to the user to provide 950 mb emmc image which he was backing up for himself.

I am grateful to you and the fellow user, because of you guys I was able to bring my dead device back to life. Keep up the good work :good::good::good:
[General Topics] Kanhaiyakr:
Plz provide the 950mb emmc image we will be grateful to u
[General Topics] Zauq:
The 950 mb emmc image isn't of "Coolpad Dazen 1" but other device "Qiku Q Terra 808". I believe you have "Coolpad Dazen 1" hence this emmc image will not help you in any way.

I suggest you to get emmc image of you device from other user but try large emmc image like 1 GB or so and try. I can give you the code to dump the bigger emmc image of your device.

Good Luck !!

The image backup process is very slow ~5kb/s .

The 100 mb image will be ready in 2-3 hours . Will try to write this on sd card and then try .

I have single backup.image and you are saying about multiple folder like image/mgfc?modem_pr .. can u explain ?? How should a backup file will look like ?? Only a single backup.img or have some folders???

Unfortunately you cannot download the emmc image, it can only be copied from a working device. As far as speed is concerned, it should not take much time to copy 1 GB. I made a copy of entire emmc after my device got unbricked and it only took 20-30 mins for 16 GB.

Try with the code I've given.

Nearly 1:30 hours gone and only 25 mb backup image created . I am creating on internal memory . The sd is not recognizing in Coolpad . IN pc it work greats.

Have u created the backup.img , as i have read from the comments u downloaded other user backup.img .

15-16 min will be for writing this image to sd card via win32 disk image writer .?? I am bit confused . Is t normal to take soo much time or my PC is slow

I have retyped the code .. and now the file backup speed is fast . Do i have to stop backup at 950 mb (unplug the device ) or the backup size will be by deafult ?

Hit THANKS if somebody help you
[General Topics] Zauq:
The code I've given is for 950 MB file. If you're using the given code then you don't need to stop in between, the final output file size would be 950 MB plus.

Writing to sdcard would depend on you pc & sdcard speed.
