Flash and ROM update China Android Smartphone all installation method Here

As Chinese android smartphones have become more and more popular, and the users also increase largely,  but we may face a problem of update our android smartphone or get a ROM to flash our phone, and then release more storage. Now we will introduce the updated guides about how to flash your android smartphone?
Note:  Don’t do it without any firmware prepared and if you wanna have a try, please do it at your own risk.
There are actually 2 steps in flashing your phone into a newer firmware.

• Card flash
• Cable flash

1. Card Flash

CARD FLASH: it means using your SD Card to install the firmware, much easier and less risky, however, you need to have the recovery installed.WHAT YOU NEED:
Micro SD Card Storage:  preferably at least 4 GB
Battery: fully charge or not below 70%

STEP BY STEP PROCESS:

• Your ROM (in zip format) send it to your SD card, Remember not to unzip, and make sure your SD card is not corrupted (blank is preferable).

• Turn off your phone, insert SD Card.

• Insert Battery, Enter RECOVERY MODE (Normally done by pressing Power Button and Volume – Key Simultaneously) Or you may use Volume Up (+) depending on your device. Hold for 8 secs until you go to Recovery Mode (Menu System with Dark background)

• When you enter Recovery Mode, You will see options (see image below). Touch Navigation doesn’t work, instead Volume Up and Down key and Power Button for confirmation or enter.

• First you need to wipe data and also data caches before flashing.

• Then choose install zip from SD card and Confirm (power button)

• After that your new ROM will be flashed to your phone, remember that if the ZIP is corrupted, security measures “installation will be aborted” or if your are trying to flash the wrong ROM.

• Reboot your phone

NOTE: if you encountered an error where your SD card is not recognized or detected by the phone, please wipe the data or format your SD card (blank) send ROM back again to SD card and then insert on phone.

2. Cable Flash

CABLE FLASH: Is much more complex and riskier. When is it used? For example, a ROM update from Android 4.2  to Android  4.4 kitkat. Where you need to install a completely new system from scratch. In this area Card Flash is practically useless.
