Unbrick Coolpad Dazen1 Qualcomm HS-USB QDloader 9008, No Fastboot

Post by Admin on Sat Jan 07, 2017 7:04 pm

This guide is applicable for hard bricked Coolpad Dazen 1 with Qualcomm HS-USB QDloader 9008, no fastboot, no led on charging, dead phone.
I am writing this guide as simple as can be for all. I no longer own this device.

DISCLAIMER: I have personally revived my Coolpad Dazen 1 (8297L-I00) using this method and tested it twice by hardbricking and unbricking my device before posting it here. I bear no responsibility of whatever that happens to your device/sdcard/computer by using this guide. 

What will you need?
• A dead Coolpad Dazen 1 (8297L-I00)
• A PC/Laptop.
• A 2GB or above MicroSD Card. (2GB would suffice)
• Win32DiskImager
• eMMC image of Coolpad Dazen 1. Download
• Stock Rom with flash tools & drivers. Download
• A little brain and common sense.

• Connect your MicroSD card to PC in mass storage mode using any card reader or old phone which supports mass storage mode.

• Format your MicroSD card in FAT32 format, quick format will work.

• Extract Coolpad Dazen 1 eMMC image to a folder. It will be of 200MB after extracting.

• Install Win32DiskImager and write Coolpad Dazen 1 eMMC image to your MicroSD card. Kindly select the right drive letter for your SD card otherwise your will severely damage any other drive or your PC hard disk.

• After successful completion of writing eMMC backup image to SD card, insert the MicroSD card in your device and remove all sim cards. Insert battery into your device now. Do not power it on yet.

• Now you can boot to fastboot mode with the eMMC image on SDCARD.

• Connect your phone in fastboot mode, steps for which are : -
A. Press and hold the Volume Up key
B. With the Volume Up key, connect the phone to your PC/Laptop with USB cable
C. Press volume up to confirm on the first screen.

• Now you can flash the stock firmware with ygdp tools. (There's plenty of guide for flashing with YGDP tools. Google is your friend) 

• DO NOT disconnect the device during flashing procedure.

• After the flashing procedure is completed, disconnect the USB cable, remove the microSD card and boot the phone normally by long pressing the Power button.

Your Coolpad Dazen 1 is unbricked now.
