PART 2

So, let me try to explain the outcome of my work and how to flash the ROM into this device.

First of all, I want to say thanks to pogodancer for his help in my investigation and for providing me the software for flashing the device, as I couldn't get any version to work.

So, getting to the point, I have created 2 versions of the firmware:

Standard Stock ROM - Rooted

This is mostly a copy of the stock rom of the device with the following changes:

- SU binaries included

- SuperUser app added

As the ROM is rooted, you can now mount as RW the /system folder and change anything you want.

Link to the firmware:http://199.91.152.132/78ww1kb2rncg/4x9ra4y3e53isjf/6820_2.3.5_c910_hteng_s5_en_4.0_v01_Root.zip

Modded Stock ROM - Rooted

This is a modified version of the rom I have done to clean the device from unwanted and chinese software and to add some missing apps. Details are:

- SU binaries included

- SuperUser app added

- Ayu_Sales.apk (CAIVS) application removed

- Go Keyboard (and all its language plugins) removed

- Default Launchers (there were 2) and theme removed.

- ADW Launcher added

- GMail added

- Google Talk added

- Gallery3D substituted by Cool 3D Gallery

And that should be all.

Link to firmware:http://199.91.152.49/yseacg4cwdkg/8i3soi585vjvyfh/6820_2.3.5_c910_hteng_s5_en_4.0_v01_Mod.zip

Now, for the flashing software, the link to get it is: http://www.mediafire.com/?o9km8vl287ev24j

Instructions for flashing, from pogodancer, are:

Quote:

0. Be sure to have installed the correct drivers. For my SC6820-device I see 5 items in Win7-32bit-device-manager (ADB-Composite, 2 x COM-ports, 2 x USB devices: all without exclamation marks). You can use the drivers from the package folder "SCI-android-usb-driver-jungo-v4-.rar".

1. Disable just in case your Win7 firewall.

2. Launch "ChannelServer.exe" from package folder "CHANNELSERVER" and allow firewall if asked.

3. Start "ResearchDownload.exe" from package folder "ResearchDownload".

4. In ResearchDownload-application chose firmware with first button (for me: 6820_2.3.5_c910_hteng_s5_en_4.0_v01.pac).

5. Be sure that the Baudrate from Win7-Device-Manager-Comports-Settings in CHANNELSERVER equals the Baudrate-settings in ResearchDownload-Settings (second button). I recommend 115.200.

6. Press the Start (Play) button in ResearchDownload-application (third button).

7. Turn off the phone.

8. Keep holding the "- volume" key.

9. Without releasing the button "- volume" plug the usb-cord from phone to Win7 (install the driver if not done before in step 0).

10. The process of firmware-burning should start now in ResearchDownload-application and take approximately 1 Minute. You can release the Vol.Button once it starts.

11. Wait until the firmware-flashing has been finished (A green sign appeares + "Passed" is written in ResearchDownload-application).

12. Remove the battery, wait 20 seconds. Put battery back and turn on the phone (first boot may take a while but not more than 5 minutes).

Please note that I have flashed the phone it in a Windows XP virtualbox machine and I realized I didn't need the CHANNELSERVER application, so I went directly to step 3.

Cheers.
