Changing Uagent Wave y + BONUS



Hey dude!
Today a very good tutorial, learn how to change your useragent its wave y.
Very simple. but need to reset (factory reset) to work.
Factory reset will erase all your data (apps, contacts, sms, …….)
It is recommended to backup your data by Kies.

First step:
You need to know how to use TK File Explorer 2.4
Download here:

Second step:
among the folder Settings/default/NV/ and save the file nv_default.ini

Third step:
Open nv_default.ini with wordpad and click Ctrl + F and search for NV_SI_UAGENT

Fourth step:
erase something like:
Mozilla/5.0 (SAMSUNG; SAMSUNG-GT-S5380B/1.0; U; Bada/2.0; pt-br) AppleWebKit/534.20 (KHTML, like Gecko) Dolfin/3.0 Mobile HVGA SMM-MMS/1.2.0 OPN-B

and set the user agent you want, EX: iphone

Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_0 like Mac OS X; en-us) AppleWebKit/532.9 (KHTML, like Gecko) Version/4.0.5 Mobile/8A293 Safari/6531.22.7

, android,

Mozilla/5.0 (Linux; U; Android 2.3.3; zh-tw; HTC_Pyramid Build/GRI40) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1

You can go where you think best testing

Fifth step:
Save the file; delete his, and pass the edit.

Sixth step:
Unplug your wave, and enter settings>General>Reset>Factory reset, enter your password reset and wait.

In the file look for the line nv_default.ini NV_SI_BATTERY_PERCENTAGE_ENABLE = 0 replace the ’0 ‘by ’1′ and save.
and go to the folder on your wave.

    sorry is that I used a translator, would be thus:

    “In the file nv_default.ini look for the line NV_SI_BATTERY_PERCENTAGE_ENABLE=0 replace the ’0 ‘by ’1? and save.
    and go to the folder on your wave.”
