DESCRIPTION


Your responsibility, don't blame me if something goes wrong, etc…

 

Coolpad = Yulong

YGDP means Yulong General Download Platform

 

This is a very simple and safe tool for flashing official coolpad CoolUI roms in CPB format.

I am not 100% sure but I think that you can't go wrong here. This tool will set stock rom on your phone or it will refuse flashing.

 

Tool can be used for Indonesian Himax Polymer. The same tool is used for flashing another rebranded F1 –Indian Micromax Nitro A310.

 

You will learn how to quickly flash factory rom, hack it with custom recovery and flash Coolpad, Himax Polymer and Micromax A310 stock roms (here)

 

Use PC with Win7 or XP system for flashing. Win8 is a bit harder to manage

 

 

Drivers

(if you had experience with Coolpad F1 and SP Flash Tool, you probably won't need these. Skip to next step)

My way was:

PDAnet, Coolpad-140208-Setup, Vcom_driver_autoinstall

Yours may be Coolpad driver, Vcom_driver_autoinstall

For Coolpad F1 and Windows 8.x 64bit use korekore1 guide

 

Vcom is most important for flashing!

 

 

Stock rom in CPB format

Download stock rom (use IDM downloader or another download manager)

 

 

YGDP Tool

Download

Password is 369, (future proof hack: if it fails one day, revert to earlier date)…

 

Here is example for Coolpad F1 flashing:

 

Start YGDP and enter password

Open_YGDP.jpg  

 

Click on Config button

Config.jpg

 

1. Choose your phone (8297w)   2. Open Coolpad stock rom (CPB format) that you downloaded 

Select.jpg  

 

Apply your selection

Wait few minutes for your rom to unpack. Click on Start button

Turn on debugging, turn off Quick Boot in settings (or take out and return the battery), turn off the phone and connect it to PC / Laptop

Wait for YGDP Tool to finish the flashing procedure

 

You are done :D

 

 

 

Bonus: Custom recovery hack (borsosg's discovery)

 

This is a very nice way to have a stock rom with custom recovery so you can flash another rom or gapps

or something else (root for example)

Prepare latest CWM or TWRP recovery (if it looks like something_bla_bla.img, rename it to: recovery.img)

Start YGDP Tool and proceed as described before. Now you are at Config, then Select, then Apply. Rom is unpacking….

 

Before you click on Start buton, find YGDP temporary folder on your C: disk

like shown in picture below:

Replace original recovery.img with your recovery.img

Click on Start button, connect the phone and continue with flashing…

 

 

Bonus 2. –Flashing rebranded Coolpad phone stock roms

 

How to flash non-8297W CPB roms (roms for TD phone, Himax and Micromax phones) with YGDP tool:

1) Open YGDP (password:369) choose the phone model (If you have TD rom , choose 8297, for Hymax and Micromax phones, select the correct model code)

 

2) Choose downloaded rom in CPB format from your hard drive.

 

3) Go on as usual with YGDP and let it unzip the CPB

 

4) When it finishes go to the root of your C drive, where the YGDP folder is and go to the folder DownFiles that it created. There are the contents of the CPB
  Look for the file ''phone.info''(there are 2 of them) and copy them to your desktop

 

5) Open one with notepad++ and find a line that says ''ProductName=8297**''(** will be different according to the cpb's origin. If for example the cpb is from India it will be    

  ProductName=8297W_I01. You now have to delete ''_I01''so that it only reads ProductName=8297W. You get the logic. You change this to whatever your phone's real code name is. If you have a Micromax phone, you add ''_I01'')

 

6) Now that you made the change save the file and do the same with the other phone.info file

7) Next find the file YL-params.bin. Again copy to desktop,open with notepad++ and find the line that says ''1.01.000.P1.8297W**''(or something very similar, you will see it, there are not many   

  lines in this file)

  Do the same as before, modify the ''**''to match your phone's code, exactly like you did with phone.info

 

8) Save the file and replace all 3 files back to that temp folder.
  (While you are there you can replace the recovery.img file too –see Recovery Hack above)

 

9) Ready. Go on with the installation on YGDP as normal.

P.S.

YGDP is just one of the several flashing tools for Coolpad F1.

If you can't make it work there is Coolpad Download Assistant and standard SP Flash Tool.

One way or another, you will manage to flash a stock rom or save your phone from a soft brick…

 

P.P.S.

Nice summary by UserDJJ:

Quote

Turn phone off, run YGDP, config ->choose right phone model ->apply (now wait untill it unpack cpb) then replace

recovery.img, click start, ? now turn phone on with power button ?, if you have proper drivers and no other phone software

is running (like nokia pc suite, kies) process should start using port com8 and should be finished in approx 5 minutes,

if cell 0 progress bar is moving that is good sign.
