- 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
- Ayu_Sales.apk (CAIVS) application removed - In case you want to know
what this app is, check your mobile phone bill. If you find SMS messages
sent to chinese numbers (starting by +13) that you have never sent, you
now know who to blame 
As the ROM is rooted, you can now mount as RW the /system folder and change anything you want.
Link to the firmware:Firmware Link (1)
- 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.

Now, for the
flashing software, the link to get it is:
DEBUG_TOOL
Instructions for flashing, from pogodancer, are:
Quote:
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.
And that should be all. As usual,
use this at your own risk and make sure you are flashing the same device or you could get a nice bootloop.
Cheers.
NB: In case anyone is wondering why flashing the firmware instead of
directly rooting it, I just want to say I have tried probably all
methods that exist (even the last version of Unlock Root that claims
being able to root a MocorDroid2.3.5 like this device). I have also
tried to do it manually via an ADB shell, but no exploit seemed to work
on this model. It is surprisingly horribly well protected. So, after
many days of fighting with it I decided it could be a better solution to
unpack the firmware, unmount it, modify it and remount it. And, after
many attempts (failed as you may imagine) I have been able to get to
these 2 working (and rooted!!) versions of the firmware.
Enjoy!!
-- EDITED --
I have just detected that there are two devices looking very similar
with same SC6820 chipset, but made by two different manufacturers:
- Feiteng A7100
- TiangJI A7100
If you happen by chance to have the second one, please DO NOT USE the
ROM in this post, as it won't work with your device. The TiangJI device
includes a TV antenna that the Feiteng does not, so please verify it
before flashing your phone (specially if you don't have a stock firmware
backup for your mobile phone).
