So I have the Motorola Defy+ (MB526) Thinking that since the Original Defy (MB525) had a GSM Band of HSDPA 1700/2100 The Defy+ should as well, But my Defy doesn't seem to work with Wind Mobile or Mobilicity Carriers (Which run on HSDPA 1700/2100), So I re-checked the Specs of the Defy+ and the bands are HSDPA 850/900/1900/2100. Is there anyway to change the frequency to 1700/2100?
Else I just bought this phone just so it doesn't work with the providers here in Canada -_-'
Please if anyone knows a way to fix this with some sort of software or hardware chip even.
Use a baseband which supports 1700/2100 mHz, as per your geographical location from the defy baseband switcher app. Rooting is a must for this app

I have 10i, but would love to switch to a provider that uses 10a frequencies. If I cross flash will the radio switch the frequencies?
It might sound like a stupid questions but my other phone is a Motorola Dext (aka Cliq) The 3G radio chipset in the Dext is multi-band, original radio firmware allowed the use of all the bands i.e 850/900/1700/1900/2100. Software updates later killed that option and allowed the phones to use 3 of the possible bands; decided by the telecom pushing the update. (Yes, I did update before finding this out -arse) BTW, if you feel bad about 1.6, Cliq/Dext sold in 2010 is stuck on 1.5, although at least there are (more or less buggy) custom 2.1 roms out now.
Apparently it's a common practice to use multiband radio and use firmware to lock it down, it is cheaper than manufacturing two distinct chips. But, common, does not mean universal.
Soooooo... Anyone knows if the radios are identical and we can cross flash to change our 3G frequencies; or are 10a and 10i using different, hardware locked, chips?
Try to use R2BA026 LAM firmware.
Is for X10a.
After that, you have to recreate the APNs.
It might work... but depends what frequency is supported by your carrier.
If is one from your X10i, it will work for sure. If not ... probably EDGE is your only choice because afaik X10 has only 3 bands for 3G
I want to go from Vodafone 900/2100 to TelecomXT 850/1900. XT has NO GSM network, it's all 3G and has superior data rates and speed. In NZ, because of large distances between towers outside the CBDs of the main centres, the first (lower) frequency is more important. Voda falls back on its gsm network and their 900MHz 3g coverage is not as good as telecom's 850 coverage. What I'm trying to establish is if the 3 frequencies are rom or hardware tied.
TelecomXT has a better network and far better prepay deals on data and sms, I used it with my 3g iphone and would love to go back to the fold.
I really don't want to brick this phone. So I've been trying to read up on how easy it is to flip back and forth with 10a/i roms. Or, flash 10i rom with a baseband? I'll try to flash in the weekend unless I get warned off,
i believe it will not work that way...x10i and x10a use two different 3g radio antenna chipset. so it will stay the same even though u have flashed to x10a firmware...

I agree. its not a software issue... its hardware... and unless you're apple, you can't get away with a software 'fix' to a hardware issue
An item you are forgetting about is each band has a power amplifier tuned specifically for that band. So even if the chipset supports 5 bands, it will only work on the bands for which it has power amplifiers for.

X10i: HSDPA 900 / 1700 / 2100
X10a: HSDPA 850 / 1900 / 2100
So, you are out of luck.
You have to trade your X10i for an X10a
Hi, I have a problem with my I9000M running JL2 : voice calls and mobile network aren't working with my videotron sim card!
I guess I need to change the HSPA/UMTS frequecies of the phone from 850/1900/2100 Mhz to Videotron frequencies (1700/2100 MHz --> Band I (2100); Band IV (1700); Band II (1900)
From what I've read in the forums, I have to flash a modem file using Odin in order to change the phone frequencies.
The T-Mobile Vibrant uses 1700/2100 MHz bands... but I'm not sure JL2 has been released in the US, so not sure i can find a compatible modem file...
Well, I'm not too sure how to solve this, if anyone could help it would be greatly appreciated.
From what I've heard up to now, change the phone's frequencies in that manner is hardly possible...
Sent from my GT-I9000M using XDA App
The i9000m does not have a 1700/2100 antenna, it has a 1900/2100 antenna. The i9000m will not work on Videotron's network. You need the SGH-T959 T-Mobile Vibrant.
I'll try to change the antenna then (to change the hardware) will find the appropriate antenna on ebay or something...I'll keep you posted to let you know if the operation is successful!

hi !
im using DEFY baseband switcher , and I was wondering, is there a difference between two different basebands with same frequencies ?
e.g between Brazil Tim 3.4.2_107-9 w frequency band 850/2100mhz & Brazil Claro 6.14.5 w same freqs ...
assuming there is , how can i tell which one is best for me?
(my retailer is not in the list...)

Why not try both for a while and find the difference. I am sure it wont have much difference for the fact both are Brazilian Base bands.
Are you running the stock or a custom ROM?

those bands were just an example...:cyclops:
i would really like to know what other parameters are in there except those freqs..
and another thing, is there a more accurate way to measure the phone connectivity strength, rather then just try using it?

I had wondered the same thing when I first moved to Eppy's CM9 builds. More specifically, how to tell which band to choose when there are multiple for (in my case) T-mobile. I really had no reference, so I fumbled through it. Is there an easy way to tell what is used in your geographical area?

Well, as for me, I'm using Central Europe baseband frequencies (as I am obviously from there) and I also have 5 options to choose from. By default, it set the second option and I had absolutely no problems regarding the strength of the signal. I compared it with my old Nokia phone which had very good coverage, Wherever the old phone had signal, my Defy also has. So I think that you should, at first, let the phone make its own settings, and then if you have bad signal where you once had no problems, try the next one and so on. Hope it helps.
And by the way I have CM9 by Epsylon3 (great guy and great and stable ROM). I'm also going for stock settings (if possible) rather than third party applications.

It depends on the frequency used by your provider. If both the baseband incirporate the frequency your operator runs on, you can use either. There won't be a difference in signal strength..
Wrong baseband= No Network
Correct baseband= Full strength.. That's it.
Correct Neo..
If You select correct baseband you will get network or else no network.
Me too using CM9 with stock baseband without any issues.
My default baseband selected is Central Europe 3.4.x where as i am using My phone in India without any issue...
I'm using central Europe baseband (900/2100, 3.4.x ) In NZ, and it's works for telecom, vodafone, and 2degrees networks.
.
.
What does the 2.34 or 3.4.x whatever mean??
Btw you can set option in System, status bar to display signal status in text format, instead of the bars to experiment. (cm9)

I think that baseband difference is mostly in 3G frequencies.
In India we just have 2100, but the base band are for HSDPA 900 / 2100
in 2G also we have some extra bands which are not used in India.
Do these extra bands drain battery?
In south korea Band we have just 2100. If we use that band in India we do get a 2G, but it is GPRS and not edge along with 2100 3G

As I said before, it depends on your provider. If your service provider uses the 3G/EDGE spectrum alike korean providers, you will get it too.. And it has nothing to do with the battery..
Im using the international i9500 and getting really bad data speed on Bell mobility in Canada. Anybody know a fix for this

The reason why you're having this issue is because the i9500 uses the same frequencies for their 3G/4G that Canada uses for 2.5G GSM. You're not going to get very fast downloads speeds and there is no fix or mod to change this. That's why Canada and the US have their own variants which work on our network frequencies.
In Canada we use 850 MHz for GSM (2.5G), 1900 MHz PCS and 2100 MHz for LTE.

So got my new baby, and I love the stock Android UI.
But I got issue connecting to LTE networks here in Germany. A friend of mine bought it in the US store and sent it over to Germany. 3G no problem, but LTE isn't working.
I checked the tech specs, and it says 4G LTE (700, 850, AWS, 1900 MHz). Here in Germany T-Mobile is using Band 3 (1800 Mhz) and Band 20 (800 Mhz) So there is the culprit.
Is this a hardware restriction, or could be solved via software? Maybe flashing a different baseband?
Unfortunatly on the Phone Info screen, you cannot change the GSM/UMTS band. The list is empty. It worked on my Nexus 4 though...
Maybe its possible with a modified modem/radio, dunno it thats correct though and how to do it. There is a radio thread on this forum http://forum.xda-developers.com/showthread.php?t=2192025, check it there.
It might be possible to change the bands using QPST (you won't be able to flash the international modem) there is already a thread on the I337 forums http://forum.xda-developers.com/showthread.php?t=2291589 that has a tutorial for enable AWS bands on the device. The process should be roughly similar assuming the device's hardware can operate at those frequencies.
If it works you will lose north American bands until you rehash the I9505G configuration back.
