I have an Huawei Ascend y210d on which I installed CWM recovery. After that I installed a custom ROM, but now I want to flash its official firmware.

But its official firmware is not installing. It got told using Huawei firmware Indian version downloaded from Huawei. I am using this procedure:

  • first copy dload (in dload folder update.app file is present) folder to the root of the SDcard
  • then turn off your device pick out battery then again insert battery
  • then press buttons volumeup+volumedown+powerbutton
  • then its start unpacking the update package But in step 2 it failed on installing.

This is the error.log I get in SD Card :

{filename = /mmc1/dload/update.app 
CMD=0xf,moduleaddr = 0xf0000000, len_tmp=0x2c54
filename = /mmc1/dload/update.app}

What can I do to get this fixed?

  • Yes my device is rooted and i have installed an Custom ROM also and update.app file is for my device i have downloaded from official website.

  • As I wrote before in a comment (which I've now removed to keep things clean – and ask you to do the same for yours, except for the last comment): if it is an update, as the listing on the download-page says, it might/will fail if it cannot detect a "valid" previous (stock) version installed on the device. The file size also indicates it only contains updated components, not a full firmware. You will need a full install. Not being familiar with Huawei devices, I have to leave detailed help to someone else.

Following the instructions, flash each UPDATE.APP in order:

  1. Transfer > put the UPDATE.APP file in a new folder sdcard\dload and run forced upgrade (vol up + down)
  2. dload (main) > overwrite UPDATE.APP in sdcard\dload, run forced upgrade again
  3. vendor > overwrite UPDATE.APP in sdcard\dload and run forced upgrade for the last time


  • the UPDATE.APP needs to be copied from each folder to sdcard\dload\
  • phone should reboot after each forced upgrade

Install Any Recovery Like CRM or TWRP....

search for "Room original del huawei y210D" in youtube. Exactly as given.... u will see one HD video link in search result.. downlaod the file mentioned in description of the vdo... Download the rom file mentioned in youtube vdo description

Wipe the OS of ur mobile. wipe cache.. and others. Keep downloaded zip file in SD card. Install using recovery.... Enjoy....

    Search for a Youtube video to read its description, to find a link to the real ROM? That doesn't sound like a trustworthy way to find software that can completely take over your phone. If you can update your answer to link directly to a trustworthy source, please do.
