Evilkilla, thanks very much for the file link, i flexed the phone with the 850 it shows 850 on the read but i keep getting no service on the phone but when it checks for networks it sees the networks but it can't register on them, any ideas

@AZFAN (cc:Evilkilla)

Because you use european flash/flex, so your cell phone doen't work for america service no matter if you change your cell into 850/1900.

I did the same thing as you mentioned above.

What we need is the flash/flex for america gsm service, it seems no one in this forum can provide these flash/flex. :(

hi, how can i flex motorola phone? i have serial cable with 9v battery power supply, will this work with victor soft?

pardon for my newbie question cuz i'm quite ignorant with moto phones :)

what phone do you have?

i don't have a phone right now, i ask this because there is this one time a client bought his t720 cingular (U.S.A.?)... it is unlocked but cannot get 900/1800 frequency...

I've downloaded the flex band_activate_900_1800mhz.zip from spunlock's site, i believe it is a victor file, I'd like to know if this flex file is a universal flex file for activating 900/1800 from other motorola models (V66,V70 etc..) and will serial cable (9v) be good for uploading flex? do I need to short pin 13/14?


thanks for the reply :)

@trafix,

The vic file for activing 900/1800 cannot be used for T720. Even if you can make a band change to 900/1800, you still cannot use it in other wirelss service provider than cingular, becaue it's locked to it.

I have no idea if you can use it in 900/1800 network after unlocking the cell phone.

I hope some one can give a report for band change (i.e. use a america T720 in Euro/Asia) after unlocking.

the phone that came my way was unlocked thus it accepts our local networks but it cant get any network due to 1900mhz...

isn't t720 a tri-band phone? (or is not? i'm not quite sure) :) thus it should work on 900/1800/1900 right?

@trafix

T720 is dual-band cell phone. You can change it to 900/1800 by entering the enginnering model. Following the below steps:

enter "menu" and "048263*", then you will enter the enginnering model

under "Opcode"

input "10*0*3" for GSM 900
"10*0*4" for GSM 1800
"10*0*5" for GSM 1900
"10*0*6" for dual band GSM 900/1800

Report here or email me if you can make it work in your local networks.

:)

thanks mate, I'll try it when the client comes back :)

I tried few weeks ago, not work, no service on the phone.

Dear Members,
Please suspend the phone with 54* before using the commands to change bands.
The sequence certainly works!
