Hello, I'm currently using 3G Files that I got here in order to activate 3G in my Defy, since my company is using 850 Mhz band and the phone is not using it by default since I bought it in another country, but, in the flex version it says "Milestone2" so I'm assuming the 3G Files are from Milestone version, I'd like to flash Froyo defy version, and now that the official firmware is out (as fas as I know) I'd like to know if someone could provide me with the 3G Files from a Defy Froyo firmware with 850 Mhz band enabled, thanks!!!
Search this forum for Baseband Switcher (i think it's on page 3)
Does this work??? thanks!!
It works on 850mhz for me using headband switcher, but my phone has an 850mhz radio, it will only work if your defy has the right radio...

Is anybody using the SK4G on AT&T? Lets not start a carrier discussion other than can it get on ATT 3G bands? I believe the samsung vibrant can. Correct me if Im wrong about that.
I doubt you would find anyone using a Sidekick $G on AT&T
The 3G (UMTS) bands supported by the SK4G are Band I (2100) and Band IV (AWS1, 1700/2100).
AT&T uses Band II (1900) and Band V (850) (at least according to http://en.wikipedia.org/wiki/UMTS_frequency_bands )
So while you could use it with the 2/2.5G (GSM/GPRS/Edge) service of AT&T, you wouldn't be able to use it with their 3G network.
Thanks. I thought that might be the case since t-mobile owns the name sidekick and there is no international version of the phone.
Is it possible to flash the radio with one more compatible with the network the person is interested in using:
It has nothing to do with the radio. Its hardware based.

Thanks for clarifying that!
Hi, I bought the defy about a month ago. I bought it in south america. I live in Italy, so, when I came back, and tried to connect with my phone to the 3g network it didn't, just the GSM (the little G on the top). I'm currently using CM 7.1, but with the Defy+ ROM it did the same. Now here's a strange thing: i searched over the internet and find out that with the Defy baseband I could change the band for the Italy one, but, I'm vodafone, and the network with Italia RT on the baseband says Emergency calls only. So I used the International RT, and it worked. I thought it may be the device, so I inserted a TIM chip, but now instead of GSM I get EDGE. WTF?
I know vodafone uses 900/1800/2100...any ideas? It is possible that because I bought it elsewhere I can not connect to 3g in europe?? (even if the defy's manual says it works on Quad band GSM with GPRS/EDGE (850/900/1800/1900 MHz in all regions)
Dual band UMTS with HSPA+/HSUPA (850/1700/2100 MHz in the USA, 900/2100 MHz in Europe, and 850/2100 MHz in Australia, New Zealand and Thailand)??
Thanks for the help!!
Please, help me get my 3G back!
No one can help me? Even a hint would be great.
Thanks

Use baseband switcher dude

As I said before: I used baseband switcher, but it doesn't change anything. I wonder if the 3G fixes on other forums are the same as baseband switcher

for 2G networks, Edge and GPRS are the data connections available.so G is for GPRS not GSM. E is for Edge (both E and G are GSM 2G). some networks have GPRS and Edge depending on the location, some only operate GRPS, it depends on the priority network planning etc..
when you tried different SIM cards you used different networks and thats why you have G or E, depends on whats available for that network in that location.
as for 3G, what country did you buy your Defy?
italy has : 900/1800 for GSM and 2100 for 3G/UMTS
south america:
-brazil has 2100 and other bands for 3G/UMTS depending on region/operator
-other countries in south america have no 2100 but only 850/900/1900
good article here on wikipedia
http://en.wikipedia.org/wiki/UMTS_frequency_bands
sadly the 3G radios in most phones are carrying one and not all frequencies so your device is as small and cheap as possible.

Does that mean that even if I use baseband if my phone doesn't have the 2100 will not work in 3g? I bought it in colombia. Thanks for the answer btw. There's any mod, way to give my phone the 2100 frequency? Maybe changing a hardware part? O just I should change the phone? If I change Rom does it do anything? Sorry for all the questions

In the box says made in brazil. Don't know if that's of any help. Any way I can change the 3g radio??
changing roms or baseband is of no use unless you have correct radio. did you use the phone in colombia? did 3G work? if 3G worked in colombia it will not work in Italy, if thats the case i think easiest is to change your phone if you want 3G, not sure if anyone tried to mod radio.

Yes it worked there. Well, thank you for the help, I think I'll keep this for a while, but at the end I'll have to change it. I'll try to ask if maybe some other company use the 850 or 900 here also for 3G. I think, if the topic is solved. Thank you nolimizz.

My unlocked T959V is working well on Bell Mobility (Canada) UMTS 850/1900 mhz only network. *#0011# indicates WCDMA 1900 Band 2 connections.
Will this phone with no WCDMA 850 mhz option not work at all on the 850 mhz only cell towers of my carrier?
If so, are there work arounds other than replacing the phone with one with UMTS 850/1900mhz support?
Toyed with the idea of trying to flash the modem with modem_I9000ugjl2.zip, but read this will not work and may brick it. Is this the case?
Thanks for any ideas.
If your phone is fine don't mess with it, especially if it's not a modem from our phone.. A tip... "If it's not broke, don't fix it. " If you feel a need to flash, report back-but it will be prob be from a computer..

Thanks.
My city coverage seems fine on only UMTS 1900. My concern is in the rural area where I vacation the cell towers have UMTS 850 only, so I guess my phone will not work at all, but will be trying it shortly.
Hi,
Is it possible to enable 850mhz 3G on the 9020T like it was done on the galaxy s (it doesn't officially support those frequencies), if yes then how can I do it (very important to me my operator uses only 2100 and 850 3G)
Here is a link to how to do it on the galaxy s : http://androidforums.com/samsung-ga...rk-frequency-your-samsung-i9000-galaxy-s.html
I tried entering service mode but when I entered the code to the dialer nothing happened...
Thanks in advance!
P.S. I'm running JellyBelly 0.1.4

i don't think the NS has the hardware to receive in 850hmz, not software limitations
Not possible. You need a i9020A for a 850MHz carrier.
OK thanks anyway!
I recently switched carrier and it uses 3g only, and only 2100 and 850mhz... so I get terrible reception and lose signal every two minutes... because of the lack of 850...
Guess I'm gonna have to upgrade to a newer phone...

I am going to Australia next week to for a couple of months.. and I think Rogers is going to update Razr HD phone in last week of January. Is it possible to get the update there in Australia? I am still resisting the temptation of rooting the phone and installing Telstra's ROM on it.
You can only OTA update while connected to the Rogers network. I would flash an Aussie ROM anyway before you go, so you can use their LTE if desired.

So what if i put the Rogers sim in while in Australia.. I will be on roaming, Will it get updated?.. Secondly.. i think i will be using telstra there but problem is that their LTE frequency is 1800 MHz and it is not supported by Razr HD we have here in Canada.

I don't think this is true - updates come from Google right? So even if you are only connected via WiFi (with the cellular data off), it should receive the update...

It doesn't matter what sim you have installed. Once you check in to the Motorola servers and there is an update sitting for your phone (as determined by your blur system version) the OTA will download.

Same phone, different rom enables/disables different LTE bands. Flashing an aussie rom should enable LTE support in Australia.

You can update every carrier rom on any network ... without network via wifi without simcard...
Again this is false you can t get telstra lte on rogers phone... you can t get dual carrier hspa (dc hspa) on a rogers phone
Rogers have only 700/1700 mhz lte band with a 21 mbits ... chip
A friend from europe francer have buy this rogers phone ... flashed the sfr rom ... have a lte simcard and lte plan on sfr in lte area and not work ....
Is not just a base band question... some peoplr say same thing for motorola defy... 3 different phone... 900/2100 850/1700/2100 850/1900 if you take a baseband 850/1900 on a 900/2100 chip the phone don t work ...

Hmm... Interesting. However, I have a TMobile Defy, default 850/1700/2100 and switched it to Argentina 850/1900 and it works on Rogers that way.
Razr HD International lists the following for LTE bands:
700 MHz Class 17, 800 MHz, 1700/2100 MHz, 1800 MHz, 2600 MHz
So you're saying that the phones for different regions are hardware limited to certain LTE bandwidths? That is different from what I've been reading. I'm not saying you're wrong, just no-one else seems to make that connection.
