Chinese Note II clone problem (Star S7100 - MTK6577)

Gorcsev.hu · Dec 27, 2012

Hi,

I have just bought a chinese Note II clone.

Code:

www dot cellphonemic dot com/mtk6577-android-phones/s7100-mtk6577

The phone seems to be unable to handle SIM properly. On every start I get the error message:

com.android.phone stopped

SIM Toolkit is also unable to start. When I start or receive a call, the display goes blank or just flashes up for a moment. (This problem is resolved already, see here)
I was told it is most likely a firmware error. On searching, I didn't find this model or similar in the forum. I also tried several rooting methods described here without success.
Here are some details I could get from the phone:

Code:

I asked the chinese merchant I bought the phone from but he seems quite uncertain, although he promised to send a new ROM.
Can anybody help? Thanks in advance

Unfortunately is often quite difficult to get support for those Chinese clone devices. I hope you'll find someone that can help you but I think your best bet is to ask the seller for a replacement.

At least I could root. Then I could try some custom ROM at my own risk.

Don't install ROMs from Galaxy Note II threads beacuse chinese versions of phones isn't the same that samsung's devices! You may brick the phone

It was never in my mind. This is why I posted here. But the question is still academic, since firmware update requires rooting (as far as I know) and I am unable even to root.

Proximity sensor

The problem of blank/flashing screen during calls has been resolved. The proximity sensor needed a proper calibration. I did the calibration many times so far, but not the correct way. I have just figured out how it should be done effectively.

Hi, can you teach me how to calibrate?

It is actually a simple process. Locate your proximity sensor, it is a small LED-like thing next to the speaker, on either side. Look for calibration of proximity sensor, you can find it usually amongst the display options. Tap on it, target-like concentric circles appear and the application asks you to place some obstacles over the sensors. The easiest way is to hold your palm above the sensor approx. 5 cm (2 inches) apart. Touch the Start button, and then try to complete the process with your hand motionless. The whole process takes a few seconds. If you did everything right, during a call, holding the phone to your ear the screen goes blank, and the phone application re-appears when moving the phone away.

Hi,

thanks for the response. How is your ROM working? Is it fully functioning, rooted or not etc.
How should it be installed? From SD card or by flashing application?
Send it anyway, having itself doesn't do any matter.

Thanks in advance

gog3219 · Jan 13, 2013

I have the exact same phone as you but mine seems to be working fine. I've tried to root it and there is no way I can find to root it. Especially since my boot menu is in Chinese! I would give you my ROM if I knew how.

Magnector · Jan 13, 2013

I guess buyers should run the risk when buying clone phone. Asking replacement seems to be the answer.

You may try to flash the original factory ROM via Flash Tool, if your phone still can be recognized.
Btw. root access can be gained by replacing the Chinese recovery with CWM recovery, then installing SU from CWM recovery.

Successfully rooted

I have just successfully rooted my phone. The process was as follows:

I replaced the Chinese factory recovery mode with CWM recovery via Flash Tool.
Started the phone with CWM recovery and installed a superuser package from it.

If anybody interested, I can provide links to files needed along with description of the process.

jigsey · Jan 26, 2013

Flashing CWM Recovery and install root

Download CWM_and_root_flash.rar from here.
Unpack the archive with its folder structure to a path not containing any special characters.

Flashing CWM Recovery:

Turn off the phone without connected to the computer.
Take out the battery and insert it back after a few seconds.
(If the driver is already installed, continue with step 5) Connect the phone to the computer with USB cable. The operating system will detect a new device - direct the wizard to the folder containing the driver (for your version of OS)
[*]When driver is installed, disconnect the cable from the computer.
Run the program SP Flash Tool.
Push the button Scatter-loading and select the file MT6577_Android_scatter_emmc.txt (it is in the folder CWM Recovery).
IMPORTANT! Make sure, only RECOVERY is selected in the image list, otherwise the phone could stop working!
Push the button Download.
Connect the phone to the computer. The program should recognize it and start flashing.
If the phone is not detected, then unplug it from the computer, remove and insert the battery and re-connect to the computer.
Also the new hardware wizard may pop up again - just let it install the driver automatically.
When flashing is complete, disconnect the phone.

Boot the phone normally to check everything works properly.

Installing root (Superuser):

Save MT6577 blk0p3 Root by CWM-SuperSU 0.99 angelobiz.zip on SD card (internal SD card is preferred).
Turn off the phone and reboot it in recovery mode by keeping pressed Volume+ and Power buttons simultaneously.
You enter CWM-based Recovery v6.0.1.2 you have just flashed. (Navigate with V+/- and choose with PWR)
Choose "install zip from sdcard" from the main menu.
Either select "choose zip from sdcard" from the next menu if you saved the zip on the external SD card
or select "choose zip from internal sdcard" if you saved the zip on the internal SD card.
Navigate to the zip and press the Power button. When the installation process is complete, reboot the phone normally.

Superuser application is now installed and you can check the root status with a root checker application.
