If you loose your 3g after flashing a rom or sbf, try to flash one of those zip to see if you get your 3g back (based on the wcdma(3g) freq your operator work on).
(Edit: in the previous sentence, "operator" was meant for the "original operator" of your phone. So in other words, select what matches your hardware, not your carrier. If you still have the original box, theres a label with the freqs on it.)

I've repacked as zip the files that seem to be resposible to gsm/WCDMA frequencies support on the Defy from several dumps (China, Poland, UK, US, all Froyo based). I'm not 100% sure though that it will work, but if it can help.
PLease report your success/failure here

Does use the customer recovery to flash, or via moto recovery?
Has anyone been able confirm that all these different variants of the Defy actually do have different hardware radios as well? Or are they all the same hardware with soft-controlled bands?
Example: If someone lives in an area where AT&T's coverage is 1900 MHz only and no 850 MHz, you shouldn't get 3G on a T-Mobile 850/1700/2100 Defy. What if you flash the 850/1900 3G files - do you get 3G now?
Do different country variants have a different FCC ID inside?
thanks.
ps. are you sure about cn850/2100?
china has cdma800, gsm900 and wcdma2100, so would make more sense to have 2100-only or 900/2100 since wcdma850 would never happen.
Mobile phones can have their 3G antennas optimized for certain frequencies. They can all work on all existing UMTS frequencies but it does suggest that different areas means different radios. Now that still doesn't mean that the radios themselves are different of course but at least it is something to look into.

i can assure you that 3g radio must be different. unless it has a quad/quint-band 3g amplifier, which doesn't exist yet. intalling multiple amps while not using all of them sounds really stupid to me

the baseband chip should be the same just the rf part is different.

I'm not 100% sure. I looked for the information yesterday on Motorola's site, specs for Defy in the respective countries. Today I can't get to the ME525 spec page on Motorola.com(chinese). So I can't confirm.
EDIT: just found it:
频率 WCDMA: 850/2100 HSDPA 7.2 Mbps; GSM: 850/900/1800/1900 GPRS; Edge Class 12

Awesome! I now have a working Defy in the Movistar Argentina 3g/H network!
Even though out of the box, the unlocked Defy made in argentina did not work with Movistar Argentina, Froyo + this fix did work. Very weird bug.. but very cool fix!
NOW I'm happy about my defy!
U.S. T-mobile on 2.21 Chinese Retail Firmware, confirmed the 3G works with the patch!!!! tks

Hey that sounds great and this was the last thing keeping me from upgrading to Froyo. I'm on Australian Telstra network (850) so are you saying I can use either of the US/CN or that last one...do you know which the Au Telstra network is based on or it doesn't matter?
Will wait to hear and then give it a try and report back...

What are the differences between these two?
THX IN ADVANCE.
Hello I live in New Zealand and we have a network here called Telecom XT which uses 3G freq: 850 & 2100 mhz.
Unfortunately all Motorola Defy sold here have their freq specified as: 3G Network: HSDPA 900 / 2100
Does this mean that I can flash the "freq_F_CN_026-850-2100-signed.zip: 850, 2100MHz (ref)" file from OP to the 900/2100 phone and the phone will operate 3G on the 850/2100 freq?
Aittle off topic here but, the vibrant has AT&T 3g and T-Mobile 3g built in. You just have to activate the AT&T 3g radio through the secret settings.
Sent from my SGH-T959 using XDA App
Mentioned this already in the Adlxmod F4D thread but I needed the 3G fix to enable reception of 2G GSM 900 MHz on my Chinese/Asian made Defy. It only detected 1800 MHz networks. I used the Chinese 850/2100 fix for this. The UK 900/2100 fix had no result which means I will probably never be able to receive UMTS on 900 MHz with this phone. Not such a big deal though because as far as I know that frequency is quite rare if used at all somewhere for 3G connections. 2G works fine now but we better rename this thread to 2G/3G fix. Not sure about other 2G frequencies though. Isn't the Defy a quad band?
Excellent...today just flashed Froyo UK version and this fix worked a treat.

noob question.. how do i install this? all i see is meta-inf and system folder
So yesterday I flashed this phone to ICS, its great, thanks guys!
However, I have a question about radio (I'm a software guy not a hardware guy).
Apparently, this phone supports Triple band UMTS 1700 1900 2100 MHz.
Rogers Wireless in Canada 'operates on the frequencies of 850/1900 MHz'
So, why can't I connect to Rogers Wireless with 3G speeds on the 1900mhz band? Does the phone require both 850 and 1900 MHz UMTS to operate 3G on a 850/1900MHz network?
The best connection I can get is EDGE and it's painfully slow...I bought this phone before I had a data plan with Rogers, so I never quite realized this issue...I guess I could just switch to WIND I just want to understand why it cant operate 3G over the 1900MHz band
3g needs 2 bands, one for upload and one for download. And that's why most phones, for example, bringing to the T-mo network you won't get 3g/ 4g speeds since it would need both the 1700/2100 bands and not a whole lot of non T-mo phones have these bands. So in your case a phone to run on Rogers with 3g would need both the 850 and 1900 bands.
the hardware should be able to operate at those frequencies but its software locked to 1700/2100 or 2100 mhz, so if you want 3g/hspa you must be on an operator which uses one of those 2 frequencies

how do i software unlock it? Does cid uunlocking do this?
Although I haven't use it, I often see 4G Rogers data connection when I'm in Wind's "away" zone. Assuming there are no other models of MT4GS (with different radios) I'm rather sure this phone can use Rogers 3G network.
According to HTC.com, this phone has the 1800 MHz LTE band (LTE band 3).
I am currently in Australia, using a Telstra LTE SIM, and I can't pick up LTE on my phone.
I tested this SIM in another phone and it gets LTE, so the problem isn't the lack of reception in my area or the SIM.
I get 3G and H data but no LTE.
I know Telstra uses 1800 MHz for LTE.
I tried changing from Global to GSM mode and all the other modes as well as all the options available in the phoneinfo app.
It seems like this device has the 1800 MHz LTE band blocked, what can be done about this?
Thanks!
So i just bought a LG G PRO 2 checked it everything seemed to work fine
But then i realized the network connection drops every few mins and reconnects only to a G signal (2G)
so upon further investigation i discover that the band frequency on this model is CDMA eg. USA + Canada
To say im P*&^ed off is an understatement clearly the person who sold me this is aware and is now ignoring any contact i try to make with him
I have contacted LG to see if i can possible purchase a motherboard for model D837 or D838 as i see this is my only option to get the device working
Unless anyone here can advise otherwise
Once i go into the band selection screen and disable CDMA bands it seems to sustain a stable connection but only to a 2G network haven't been into a 4G area as of yet to test but it is completely incapable of connection to a 3G frequency within the uk which i will be connected to 80% of the time
not 100% with the F350 but the frequencies for it should be:
2G: GSM 850 / 900 / 1800 / 1900 MHz
3G: UMTS 2100 MHz
4G: LTE 850 / 1800 MHz
2G is fine, as UK uses 900/1800.
3G: all UK networks at 2100.
4G: only EE/3 use the 1800MHz frequency. no-one uses 850 in UK.
look around the forum for the secret menu and see if you need to enable 3G/4G manually. or do a manual firmware update.
,My Wife has an F320S (G2)and she can enable all Bands in the Hidden Menu and works fine in Europe in Austria.Network Operator is Three (HG3).
I think the F350S is the same.
Go to Dialer and tipe 5457#*350#
in Modem Settings can you aktivate all Bands what you need
I hope this works for you.
Thanks for the reply guys
There's loads of settings in the hidden menu
I cant see how changing anything in here will help as it is a CDMA device which means it physically does not have the necessary hardware to connect to a 3G network in the UK
As it uses a totally different technology than UMTS
Ive discovered at WCDMA is actually UMTS so i cant see why it doesn't work ?

Those are the default settings that the device is on so no joy with that thanks anyway
using my EE sim signal drops frequently using my daughters O2 sim it seems to sustain a connection but again only to 2G network
Clearly the problem is the WCDMA bands on the device are 850 / 1900 / 2100 while 2100 is used here 900 is the more widely available and thus incompatible with device
I think my only option is to sell it on but to who its no use to anyone in the UK really

Just sold on ebay for £165 but its to someone in brazil with 4 feedback
Just missed it.
It's back up as the winner was obviously a scammer
I got this korean version of lg g2 320s. This is for the SK Telecom carrier in S Korea. When I use this in India, I am able to use only gprs on this. I have tried setting the apns manually but not able to get 2G or 3G to work.
When i go to network settings it shows only 2 options for Network Mode. first is LTE preferred and second is 3G only. My carrier Idea says i need to select wcdma which i don't see.
I went thru some forums before posting here and tried 5457#*320# i tried changing band selection but still my device wont get 2G or 3G signal.
Then I thought this problem may be because of the OS, so I rooted my phone and installed Cynogenmod 12 custom Lollipop ROM for my phone.
Now I see following options to select for the preferred network type:
WCDMA preferred
GSM only
WCDMA only
GSM auto(PRL)
CDMA auto(PRL)
In spite of selecting WCDMA preferred my phone shows network type as "GPRS". I tried changing the bands but it also didn't help.
These are the bands I see in radio switcher.
Euro Band (GSM-900/DCS-1800/WCDMA-IMT-2000)
USA Band (GSM-850/PCS-1900/WCDMA-850/WCDMA-PCS-1900)
For India following networks a re supported.
2G capabilities -- GSM 900, GSM 1800
3G capabilities - UMTS 2100
4G capabilities - LTE 1800, LTE 2300
It would be great if you can guide me to the right forum to get some pointers
Thanks in advance.
