Have you lost your IMEI and you can't call or even use WiFi and Bluetooth? Is your Redmi 1 WCDMA bricked? Follow this guide to repair it.

WARNING!!!  I am not responsible for bricked/damaged devices, loss of data etc.
For Redmi Note WCDMA with 2GB of RAM use this image! I haven't tried it myself so be careful!



  • If your Redmi is bricked, go directly to Unbrick section.
  • Do a backup of your current /NVRAM partition with TWRP. Here is the tutorial by @punkthemonk

    ============================================================================================

  • Check your Baseband in Settings -> About phone.  If it says Unknown, you flashed ROM with wrong baseband.

    ============================================================================================

  • Check also Wi-Fi MAC address in Settings -> About phone -> Status and Available networks in Settings -> Wi-Fi settings. If MAC address contains double 0 in one or more blocks and in Available networks exists nvram warning err = 0x10, your /NVRAM partition is corrupted.

    ============================================================================================

  • If you have only wrong baseband, go to Baseband section. If you have corrupted /NVRAM partiton too, go to NVRAM section.

    ============================================================================================
    ============================================================================================


Baseband/Unbrick

  • Download SP Flash Tool and full MIUI 6 ROM image (Stable 5 MIUI V5 here).

    ============================================================================================

  • Unzip Redmi_WCDMA_5.6.4_image.zip and open:

    - dpinst.exe from MTK-Driver/Win7 folder if your operating system is Windows 7/8/8.1 32 bit.
    - Dpinst64.exe from MTK-Driver/Win7 folder if your operating system is Windows 7/8/8.1 64 bit.
    - Installdriver.exe from MTK-Driver/XP_Vista folder if your operating system is Windows XP/Vista 32 bit.
    - installdrv64.exe from MTK-Driver/XP_Vista folder if your operating system is Windows XP/Vista 64 bit.

    For Windows 8/8.1 you have to disable Driver signature check before installation. Here is the tutorial.

    ============================================================================================

  • Open flash_tool.exe from SP_Flash_Tool_v5.1352.01 folder.

    ============================================================================================

  • Click Scatter-loading and select MT6589_Android_scatter_emmc.txt from HM2013023_images_5.6.4_4.4/images/ folder. Choose Firmware Upgrade and click Download. Turn off your Redmi and pull out the battery. Connect it to the computer and after 3 seconds insert the battery.

    ============================================================================================
  • When you see the green circle, disconnect the phone and close SP Flash Tool.

    ============================================================================================

    Enjoy your fully working Xiaomi Redmi!

    ============================================================================================
    ============================================================================================


NVRAM

  • ============================================================================================


  • Unzip Redmi_WCDMA_5.6.4_image.zip and open:

    - dpinst.exe from MTK-Driver/Win7 folder if your operating system is Windows 7/8/8.1 32 bit.
    - Dpinst64.exe from MTK-Driver/Win7 folder if your operating system is Windows 7/8/8.1 64 bit.
    - Installdriver.exe from MTK-Driver/XP_Vista folder if your operating system is Windows XP/Vista 32 bit.
    - installdrv64.exe from MTK-Driver/XP_Vista folder if your operating system is Windows XP/Vista 64 bit.

    For Windows 8/8.1 you have to disable Driver signature check before installation. Here is the tutorial.

    ============================================================================================

  • Open flash_tool.exe from SP_Flash_Tool_v5.1352.01 folder.

    ============================================================================================

  • Click Scatter-loading and select MT6589_Android_scatter_emmc.txt from HM2013023_images_5.6.4_4.4/images/.

    ============================================================================================

  • Click Format. Turn off your Redmi and pull out the battery. Connect it to the computer and after 3 seconds insert the battery.

    ============================================================================================

  • When you see the green circle, disconnect the phone. Choose Download Only and click Download and connect it to the computer again. After 3 seconds insert the battery.

    ============================================================================================

  • When you see the green circle, close SP Flash Tool and disconnect the phone. Unzip imei&sn writer v1.5.3.rar and open IMEI&SN Writer.exe.

    ============================================================================================

  • Select SMART PHONE under PlatForm.

    ============================================================================================

  • Check all positions in Write Item section except SN.

    ============================================================================================

  • Input IMEI_1 and IMEI_2 from your phone box (both are the same), BT and WIFI MAC addresses (from e.g. old, unused phone) without colons and double 0 in each section.

    writer.PNG


    WARNING!!! Writing random or other people's IMEI and MAC addresses is illegal!!!

    ============================================================================================

  • Click Select DB. In first window choose BPLGUInfoCustomAppSrcP_MT6589_S00_MOLY_WR8_W1248_MD_WG_MP_V47_P9_1_3g_n and in second APDB_MT6589_S01_MAIN2.1_W10.24. Both are from HM2013023_images_5.6.4_4.4/images/

    ============================================================================================

  • Put in the battery. Click Start. Connect your phone and disconnect after you see MI logo. Then immediately connect the phone and wait.

    ============================================================================================

  • When the program has finished, disconnect the phone and click Exit.

    ============================================================================================

  • Delete the backup of corrupted NVRAM and do a backup of your current /NVRAM partition with TWRP. Here is the tutorial by @punkthemonk.

    ============================================================================================

    Enjoy your fully working Xiaomi Redmi

IMEI is lost when you format whole EMMC... You format NVRAM partition and then IMEI and mac is lost.
