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
I see in the development section there is a way to flash files to restore 3G coverage and one of the files has the 850 & 2100mhz that our Telecom XT network uses. Does this mean I can flash this file to enable those frequencies on this phone or does it mean that the Chinese versions of Defy have a different chip that supports the different frequency?
Hey,
Unless the Defy has a tri band WCDMA chip (which im pretty sure it doesn't) then you can't simply flash new radio firmware/RIL to enable frequencies.
If you want an XT compatible desire, your best bet is something from T-Mobile or more ideally Telstra Australia's NextG network, which is the same as XT. Mobicity for example sells NextG handsets which will work perfectly on XT.
If you have the 900mhz Defy i believe you are limited to Vodafone/2Degrees. Flashing these Radio/RIL fixes i think were because those with 850mhz handsets with issues running radios designed for 900mhz.
Just to confirm, Defy hardware can only do certain pairs of frequencies (e.g. as say mentioned on gsmarena.com) irrespective of what ROM is put on it ?
Is there anyway to find out (from model/serial number or other way) what hardware one has ? (for 3G frequency)
I'm pretty sure about mine, though I bought this Defy 2nd-hand and flashed it, so just wanted to be sure. (I flashed it with 900/2100 MHz ROM and it seems to work fine on T-Mobile 3G in London, UK. But wonder if there is a way to check - perhaps for another unit....)
Hi everyone,
Was wondering if anyone was having problems with the following setup:
- Desire HD running Android Revolution HD 5.1.7 (will update later)
- T-Mobile
- 12.54.60.25_26.09.04.11_M2 Radio
Since flashing this radio/upgrading to this version of the Revolution HD rom about 10 days ago I've noticed a huge performance boost from the battery. However I think the radio is causing problems as I'm unable to send/receive MMS messages or have any 3G/HSDPA signal..
I've been over in Canada and noticed I was unable to get 3G speeds and was always stuck on Edge. I put this down to being in another country and Fido said I had the European version of the phone which wasn't compatible with their data network. I was a bit surprised because I figured the phone was compatible with all frequencies (as covered on the Tech Specs page of htc.com)but I'm not sure whether that lists the frequencies for say the "European" version of the phone *and* the "North American" version of the phone..
HSPA Frequencies in Europe (PCS): 900 / 2100
HSPA Frequencies in North America (PCS): 850 / 1900
The Telus DHD and Inspire 4G are the exact same device internally, the only difference is the "AT&T" in chrome on the metal housing rather than "HTC" on it for the Inspire 4G.
Every other DHD will not support north american bands, thats why you're limited to EDGE, since its the highest GSM gets (which supports the north american frequencies since that radio controller is quadband)
Not only that, but apn settings need to be entered for any data to work correctly (even if the frequencies are supported)
The general HTC Webpage shows the European/Asian frequency support of the phone, unless you choose a north american portal (US/Can)

Thanks for the response.
..Just realised I forgot to finish the post! (I'm blaming Jetlag).
..Anyway I got back to the UK on Thursday and have been unable to get 3G/MMS since I returned. I've walked all around the city today and at no point have I got anything other than Edge or GPRS coverage.
I've checked all the APN settings etc and all is fine.
I am sorry guys .. but i am tired of researching on this ... I got this Telus desire which one of my clients brought from Canada and the problem is the device wont get connected to 3g/ hsdpa . There is no " H" or 3G coming up what so ever .
I have tried the same SIM card on my desire HD and HD2 running Wp7 and i get a proper H with full signal .
I was on stock ROM and then flashed Leedroid latest ROM with 32.56.00.32U_5.17.05.08 as the radio but that didnt help .
on my research i found THIS thread which was moved and then following the guy who posted it .. i found the patch ( attached ) but none seems to resolve my problem here .
Under mobile network settings i have GSM/ WCDMA auto selected and i am damn sure about the APN .
What am i doing wrong .. Any help will be appreciated
There is nothing you can do about that. The error is not software but hardware related, there are 3 different Desires that cover different 3G frequencies. You won't get a 3g signal with a Telus Desire in Europe, because it doesn't have the European 3g bands.
Thanks for that
Don't know enough to be specific about your issue but the two GSM Desires share common 2100MHz 3G Band I, a8183 has a 850MHz Band VII and the a8181 has a 900MHz band V. Both ar quad band 2G
So you need to check whether or not the current carrier supports 2100MHz(which it sounds like it doesn't) and the model of the handset. You would have to Google to see what bands Telus transmits at.
I purchased the newly released UMI X2 Android phone. I am unable to use the TMobile 3G network. I am only able to use 2G/EDGE.
Voice and data quality are very bad, almost the phone is unusable. I spoke with T-Mobile and was informed that my modem does not support 1700 MHz and there are effort to re-farm TMobile network to support 3G on 1900Mhz but not set date yet. When I scan for available network I get three networks were available
T-Mobile 2G
AT&T 3G
AT&T 2G
Operating System: Android 4.2.1 OS
Processor: 1.2GHz MTK MT6589 quad-core processor
Connectivity Technology: GSM network & WCDMA - Standard SIM card

Did you make any progress with this? I recently purchased UMI X2, for use with T-Mobile UK. But have the same problem of not being able to connect to 3G networks - it works okay on 2G/EDGE.
I know the phone supports 3G on 2100MHz, and there's been some debate whether it supports 850/900MHz as well, but I've not found a definitive answer to that.
There's an operator in the UK (Hutchinson 3G UK Ltd) that only have a license for 2100MHz. So I was expecting the phone to work fine on their network- but no go... phone won't register on network at all - even though it shows in the available networks list.
I'm now searching to see if anyone else has been having problems - as it's beginning to look like faulty phone hardware - rather than trying to use unsupported frequencies...
acid meaand
I am still in the same situation, I am unable to use the 3G network for T-Mobile.
I am looking into getting 4G Wireless Hotspot modem $50 from the same carrier, use my SIM card on the modem, and use my UMI X2 as pure IP phone. There are many issues, but it looks promising.
Please keep me updated with any progress you make.

I have the same problem...
I have this same problem with a operator here in Brazil. Every 3G operator in Brazil, using 2.1GHz band, works fine except one: VIVO.
I can see the network when I click on "manual search", but the phone can't connect. My baseband is:
moly.wr8.w1248.md.wg.mp.v7.p1 2013/04/10 00:39
How can change this baseband to another? I tried to update firmware but unfortunately the newest firmware has the same baseband version.
firmware update will not solve the problem
Firmware update will not solve the problem. Until the manufacture identifies the problem and provides a solution, the problem is outstanding.
Beside the hardware has to be compatible and can support more frequencies which no one can confirm for the UMI or any other chines unlocked phones.
But, this is just my humble opinion.
I Found a solution (at least for me)
I think I found a solution for my problem. I flashed this very new (2013/07/17) rom, with a new baseband MOLY.WR8.W1248.MD.WG.MP.V7.F2.P1, 2013/07/10 23:14 that corrects 3G dropouts and disconnects. Now my 3g works find, with H and sometimes H+. Fast and reliable like it should be. The link for this new ROM is:
http://www.needrom.com/mobile/umi-x2-based-official-for-europeus/
Thanks for the update.
I have two questions.
1- There are two files in the link you provided UMI-X2-basedon_Official_250613.zip and UPDATE_UMI-X2-THB-ROM-based_on_Official_170713.zip. Which do use?
2- You mentioned the updated corrected 3G dropouts and disconnects, but do you know if the update have these frequencies to get 3G?
3G (850, 900, 1700, 1900, 2100 MHz)
HSPA+ 42
P.S
GSM/EDGE/GPRS (850, 900, 1800, 1900 MHz) original specs

I used the file UPDATE_UMI-X2-THB-ROM-based_on_Official_170713.zip. It was based on the Official ROM from 07/17/2013, but I was unable to find the official stock version. This version has a very new bandbase that, supposedly, fixed the problem with 3G on some operators.
3G on Brazil is on 2100 MHz, sometimes on 850MHz but in my case the problem was on 2.1GHz band. Three WCDMA operators in Brazil, all in the same 2.1GHz frequency, work fine, but VIVO doesn't. Now, with the new rom, it works with no drop outs for over a day now.
no changes or additional frequencies
I successfully applied the update but no changes or additional frequencies
I have serious issues with HSDPA, t-mobile uk works but only on GPRS and it keeps dropping out. GiffGaff seems to work without dropping out. It has worked for a minute on HSDPA today but only once. Other than that t-mobile has been dropping out badly. GPRS works for a bit then it drops out. I have took an MTK modem log with MobileUncle Tools to see what it says but haven't looked at it yet. Trying to work out if it is a hardware issue or Baseband.
I get this from my X2 Radio Logcat:

Hi,
do you have a description and a photo of how you did it?
How long the Cu wire has to be? And where to connect it?
Many thanks in advance.
Hi, i have a big problem with my LG G3 bought on january of this year. the version is the D855, italian warranty (as i am italian). from the moment which i put my SIM into the cell phone i noticed that it doesn't connect to 4G network (as just it found a 4G connectivity it started to search another network till it'd have found a 3G/H+ connectivity), delivered twice to the customer service (so i staied two months without mobile), LG wasn't able to solve the issue said that their test on the network was all right, now i found the only one provider that works with my device (i'm talking about H3G, before,when i bought it, i had Vodafone, but i have tried Wind and Tim though), but now i want to change it because it costs an arm and a leg, and i want to solve this problem by myself (as LG do nothing to solve it) and it seems there is no one with my same issue in the world wide, so what it would be a probably solution??? ask for other infos if you need!!!

If LG found nothing wrong with your device, and and only one operator has 4G working on that phone, it means that your phone doesn't support the bands other carriers are offering.
LTE bands for this phone (855) are 700 Mhz,800 Mhz, 900Mhz, 1800 Mhz, 2100Mhz, 2300 Mhz and 2600 Mhz.
Also, worth noticing is that the coverage differs from carrier to carrier.

i don't think that the problem is that, here are the LTE bands of the main italian carriers (included H3G):
-Telecom Italia: 800 MHz, 1800 MHz, 2600 MHz;
-Vodafone Italia: 800 MHz, 1800 MHz, 2600 MHz;
-Wind Telecomunicazioni: 800 MHz, 2600 MHz;
-H3G (3 Italia): 1800 MHz, 2600 MHz.
i have tried each one of these but the only one that works is H3G indeed and besides is the only one that doesn't own the 800 MHz band, so maybe the problem is that my mobile is not able to connect on this band (although it is available as you mentioned in your specs ). so is there a solution? p.s. on my old G2 work all four of them so it is undeniable that my G3 has a problem, i want just know if this problem is resolvable by myself and how!
whatever thank you for the help
