STEP 1 In folder CWM_v6.0.3.4_S820_CN\target_bin Find “Checksum” Change from value

Open file FLASH TOOLS.exe (Ingredients No.1)

Click on “SCATTER-LOADING” then go into folder of CWM CN that you’ve extracted before.

EBR2 : Use file from (Ingredients No.4)

Then, the result will be like this :

After all checked, next steps are : 1. Check the “DA DL ALL With Check Sum”2. Click ”Firmware -> Upgrade”

*the bottom of the flashtool will be like this below :

*wait until the ‘usb’ turn into ‘searching’

3. Remove battery, simcard, memory card from your phone.4. Plugged in your phone to PC

*if the green circle, come out. That’s mean, the process is finish 5. Close The SP Flashtool 6. Unplugged your phone from PC (Don’t turn on your phone yet…!!)

STEP 2

1. Open again the SP Flashtools.

2. Click “SCATTER-LOADING”, then go to folder CWM CN again CWM_v6.0.3.4_S820_CN \ target.bin \ MT6589_Android_scatter_emmc

3. Check “DA DL ALL With Check Sum”4. Click “DOWNLOAD”

See this pic :

Just like before, wait until the ‘usb’ turn into ‘searching’ then plugged your phone. (remember, your phone must off, and without sdcard, simcard and battery attach) 5. Wait until the green circle come out. Unplugged your phone. Then close the flashtool

6. Don’t turn on your phone yet…

STEP 3 Because your phone is still off, use card reader then copy these files into your memory

card. 1. Viberom (Ingredients No.5) 2. Superuser.zip (Ingredients No.6) 3. GAPPS.zip (Ingredients No.7)

Attach everything to your phone. (Simcard, memory card, battery) Go into CWM mode

( Hold vol up + vol down + Power … wait until you’re in to cwm mode) My standard operation before installing new rom :

- wipe data/factory reset - wipe cache partition - mount and storage -> format /system - advanced -> wipe dalvik cache

Install zip from sdcard VIBEROM_V1.0_1401_2_DEV_S820_NK.zip Install zip from sdcard superuser.zip (rooting) Reboot (First boot will take a while, around 1-3 minute) After booting into viberom, choose language, then next next until go into homescreen.

Check wether icon superuser is available, if not, then the rooting process is failed. Just boot into cwm again, and install the superuser.zip again, then reboot.

After viberom is installed, there’s no Playstore available. You can’t add google account yet. Solution is, reboot into recovery (CWM) , then install GAPPS.zip

Reboot now !

*NOTE* For those who doesn’t know how to add Developer Option (for USB Debugging) in menu. Go to : About phone Version Infos Build Number (click here, until “you are … developer” pop out) Back ke setting system Now you have Developer options
