Mr. Wang

 

Please Not after upgradation of S226 situation become worse now.

 

Major issue regarding Battery Legging very fastly, provide backup for less then 16HR. over night charge & after half day Battery indication Red.

 

Application issue, many error comming after upgradation.

 

Hopefully JB OS is more versatile than Kitkat for this Hardware.

 

Do not provide what your hardware didn't capable to handle.

 

& Degradation of OS now not possible And if..plz guide me.

 

Thanks

 

Kaushik Dholariya

You should download them on PC.
Recovery files are not necessary if you are using official rom. First
download the file and extract it. You will find sp tool and jelly bean rom
inside.

Also you will require some drivers which you can find on google. Check the
procedure at XDA developers website. Every thing is there.

Also remember to get backup of imei and mac addresses. For this various
methods are available.

If still you want more help email me on naivedh@gmail.com.

Ok. But I will not be responsible for any damage or Soft brick. Do at your own risk.

 

Please back up your data which is in internal storage. also Contact and SMS.

 

First download USB driver and Jelly bean rom.

 

1) Download the mobile uncle app on your android mobile and backup the IMEI and MAC-Add (It is Mandatory) Or note down. (IMEI Slot1, IMEI Slot2, S/N, WIFI Mac-Add, Bluetooth Mac-Add).

 

2) Frist install the MediaTek USB driver on your PC. Without driver nothing will work. Instruction has given on above link.

 

3) Extract the P780_ROW_S124_140403.rar there you will find the folder SP_Flash_Tool_v3.1304.0.119. Inside the folder find Flash_tool.exe and run it.

 

4) Click Scatter-loading button to load the correct scatter file MT6589_Android_scatter_emmc.txt.

 

5) Turn off your phone, wait for 15 sec after turn off. (and don't turn on the phone).

 

6) Check mark the DA DL All with checksum.

 

7) Hit Download button. Pink Progress bar will appear. Wail for complete the process.

 

8) Now connect the phone with USB cable. Download progress will start. **Don't interrupt this process as it can potentially brick your device.

 

9) One Green Circle will come after successful installation. Now you can switch on your handset.

 

If you lost the IMEI and Mac-Add then restore using mobile uncle tool. For manual entry you will need IMEI_writer_permanent and SP tool Driver.
