Cherry Mobile Emerald Kitkat Update and to unbrick your phone

This firmware is for Cherry Mobile Emerald. You can use this firmware to unbrick or to update your phone to Kitkat version.

The firmware is not rooted. If you want to root this phone you can use vRoot to root it.

You can fix the following issue in your phone:
1. Bootloop
2. Damaged System UI
3. TP Upgrade only
4. Dead phone but it is detected in computer
5. Remove Gmail Account / Password / Pattern Lock (Alternative Way)

Firmware Here -->Cherry Mobile Emerald Kitkat
VCOM Driver -->VCOM Manual
Alternative Driver --> AutoInstaller
SPFlashTool --> LatestVersion 

"Use WinRar or 7zip to extract the firmware"
"Extract the files to your desired folder"
"If you encounter error in flashtool, use different version of it."

"I suggest to use 32bit Windows OS for compatibility of the driver"

Installing Driver with AutoInstaller

First try the Alternative Driver, which is the AutoInstaller. Just open the install.exe then it will automatically install the driver. To fully check if the driver is correctly installed in your computer. 

Follow these steps:
  1. Turn off your phone (always powered off is a must)
  2. Press and hold volume up or down, or you can simple press the two button.
  3. Insert your USB cable without releasing the VOLUME button(s).
  4. In your computer, it must detect your phone and it will install the MTK Preloader or Mediatek USB VCOM driver.
  5. Repeat 1 to 4 if it does not detect your phone.
  6. If MTK Preloader/Mediatek USB VCOM Driver is installed you are good to go in flashing your phone ^_^

Installing Manually using VCOM Driver

When installing it manually your phone must be turned off, then connect it to your computer/laptop while pressing VOLUME UP or VOLUME DOWN. This will detect and look for the driver.

 1. This is the first time that you will connect your phone and it will search for the correct driver.

2. Check include this location ... ... and click on browse. Look for USB VCOM Driver and Click on 2K_XP_COM folder if you are using Windows XP or Win7 for Windows 7 and then press OK when you are done picking the right folder for the driver.

3. If the driver is successfully installed MediaTek DA USB VCOM will appear in the New Hardware Wizard.

"Your Phone must be turned off when you are ready to connect and flash your phone"

1. Launch FlashTool (flash_tool.exe)
2. In Flashtool, Click on Scatter-Loading, and load your scatter file. (see example below)

 3. After you load the file, press Press Download to Flash your Phone.

4. After you press Download Follow these steps
  • Turn off your phone (always powered off is a must)
  • Press and HOLD volume UP or Down or you can simply press it simultaneously
  • Insert your USB cable without releasing the VOLUME button(s).
  • Keep on repeating until Flashtool detected your phone.
5. If successfully detected just wait until the progress bar reaches 100%. If your phone did not automatically turn on after flashing, remove battery and USB cable. And put back your battery then turn on your device.

"Hard reset your phone after flashing"

Some workarounds:
If you encounter PMT_Changed error here is what you do:
In Latest version of Flashtool
  1. Load the scatter file
  2. Choose Format all + Download (Underneath Scatter-loading file)
  3. Then Click Download and wait until it is done flashing
For Invalid IMEI:Your Phone/Tablet must be rooted first
Restore yong IMEI in MTKDroidTools version 2.5.3. You will have this error when you format your phone in Flashtool as I had experienced. To restore download MTKDroidTools version 2.5.3 After you extract the file. Open the green robot, you must enable the usb debugging in your phone. It is usually located in Settings>Devoloper Mode then look for usb debugging. After enabling it. Connect your phone in your computer then in MTKDroidTool click on ROOT. Wait for it to finish, then Click in IMEI/NVRAM, input 15 number in each box. Then click REPLACE. Then click Reboot or you can manually turn off your phone. Then turn your phone on again. You can see that you have fully restored your IMEI. 

FOR DAMAGED BASEBAND or UNKNOWN BASEBAND (Your phone must be rooted first)

1. Make sure you have MTKDROIDSTOOL version 2.4.8 or version 2.5.3 (you can search it in google)
2.  In MTKDroidstool (I assume you launch the tool) -- Click in Root. 
3. In your device -- After you press Root, you need to authorize it. A pop up message will appear. Click Allow/Authorize depends on your root application.
4. In MTKDroidsTool -- Click in IMEI/NVRAM, then click in RESTORE.
5. Then look for the folder where you extracted the NVRAM files.
6. Check if the Baseband is fixed. And if the IMEI is fully restored.
7. If Baseband is still Unknown and IMEI is invalid. Then you need to hard reset first your phone.
8. After hard reset your baseband should be fixed already. (base on my experience)
9. If your baseband is fixed sometimes the IMEI is still invalid. So you need to restore the IMEI.
10.  To restore IMEI follow Step 1-4, but you should not restore. You should fill the IMEI then click REPLACE. Then reboot your phone.  VOILA! I hope the phone is fully working :)

I hope this tutorial help you. Please drop a comment if something is not clear to you.
