Hi there,

I have a Telecom ZTE V9 light which I've just upgraded to 2.2 from 2.1. All went exceptionally well ...until..... I realised I can no longer get XT coverage in my suburb yet I can in Wellington. I assume I have lost the 850mhz frequency but can still get the 2100mhz in Wellington central.

Any ideas anyone?

hello,

yes you would lose 850 frequency and I would be surprised if your texting is working as well. Can you tell me where did you find the upgrade?

I only upgraded because I needed tethering for work. Any solution to getting it back?

Had this happen with a motorola defy. It seems some manufacturers don't have a universal radio/baseband. You need to push the 850mhz radio files back to the device. For the defy these were often listed as being a USA 3g fix.

My google fu has returned nothing trying to find these files though. Probably will end up having to extract them out from a stock rom.

Hi mesak, I have the exact same problem as you.. what did you do to resolve this in the end?

Also, does anyone have the stock rom to pull the radio files from? Need to know more about these radio files!!! What are they, how do they work, where can I get some, how do I use them...

ZTE have already release a 2.2 upgrade for Optus in Australia. Telecom would just need to reapply their customisations.

$140 for a reflash is daylight robbery. Assuming they've got the image it's maybe a 20 minute job, about 15 minutes of which would be wandering off to get a coffee while the progress bar moved across the screen.

If they have to send it overseas because their local tecs can't do it, then that's poor planning on their part.

When I tried the Optus 2.2 upgrade I found it quite sluggish, and also without support for 850MHz. I would love to know what exactly Telecom do to enable 850MHz it surely cant be that difficult?

I couldn't agree with you more, which is why I'm looking for another solution. Telegistics is the company that re-flash them so they don't send the phones overseas.. maybe their coffee is just really expensive?

Hi. Have you tried setting the band manually? As a last resort I would try this.

You can either use an app called AnyCut from the market and create a shortcut to "Phone Info"
or dial *#*#4636#*#* and select "phone information".

Then press the "Menu" key and select "Select Radio Band".

It should give you an option for Automatic/Euro/USA/Japan/Aus/Aus2

I believe we're Aus2 (or you can try USA to force 850).

Thanks for the suggestion, someone suggested I try *#*#4646#*#* and when I did.. nothing happened at all. I can see that the number you have provided is different so it may work. I will try it when I get home and let you know if it worked.

Whoops, I suspect that was my fault, sorry. 4636 is the correct number.

I entered the number but nothing happened, no service menu or anything.

I installed AnyCut and made a shortcut to "phoneinfo" from there I have the following options:

-set preferred network type (dropdown list)

-turn off radio (button)

-SMSC: (text field with two buttons next to it:Update & Refresh)

-toggle DNS check (button)

-OEM-specific info/settings (greyed out button)

The options in the dropdown list for 'set preferred network type ' are:

-WCDMA preferred

-GSM only

-WCDMA only

-GSM auto (PRL)

-CDMA auto (PRL)

-CDMA only

-EvDo only

-GSM/CDMA auto (PRL)

-Unknown

Any idea which one I should choose? Or where to go from here?

Interesting. In all my Androids its always shown in the phone info -> menu button screen.

Is there a More option? Could be hidden there.

Changing wcdma/gsm preferences is not going to help you.

Whoops, you're absolutely right, I missed the step where you said to click the menu button.

Clicking the menu button gave me the option to 'select radio band'. I chose 'AUS2 Band' and it says it was successful. Then I assume I am meant to reboot the phone? But when I do it still doesn't connect me. Have also tried the same with 'USA Band' with the same result. Am I missing something else?

THat should really have worked. as a last resort you could try the Telstra 2.2 update, since they use 850Mhz too.

Flashing with Optus now, then will try again. Also just noticed that the IMEI on the phone is different to the IMEI of the box it came in. I wonder if it got changed when flashing it at some point. This might be a stupid question but: Would the wrong IMEI on the phone stop it from connecting?
