how to flash different baseband - Xperia Z3 Compact Q&A, Help & Troubleshooting

hi guys, do you know how to change baseband? I mean for example I am on 5.1.1 stock FW customized CH, is it possible to flash say US baseband in it without losing any data? how?
this would help a lot people using my rom in other countries!
I tried with flashtool, flashing only all AMSS_xxx parts from a US fw to my current CH install, but the baseband shown in settings is always the same, so I think I am doing something wrong/the AMSS parts are not really the baseband?
can you help!?
TIA!!

I think better to change phone baseband is changed mode to USA: If you click on dial * # * # 4636 # * # * and select info mobile and you select in the new screen menu (top right) and you can change to US networks.
I've done this several days ago. I'm in Spain and I could not access European 3G and 2G network because new newtork is for usa (LTE same).
I was doing research for improving the signal and great failure. Then I had to flash with flashtool new rom ... hehe
Sorry for my bad English.

thanks mate! i don't need us band actually, I'm in Italy and the European band is fine for me but wanted to know how to do that for us users of my rom. great tip will suggest them to do so hopefully they'll improve the signal strength/switch speed thanks again!

Hope someone can help you out, I love your rom and I just got a d5833 from Hong Kong, I live in Australia and my carrier supports exactly 5833 lte bands (I'm Italian too Btw ☺), lte is actually working but reception isn't good, I'm sure with the right baseband would be better. Thanks for the hard work ?

did you try the method suggested by Joreb? ( *#*#4636#*#* and then chosing USA band)
he was saying basebands are all the same in all d5803 firmwares

Well I did and it wasn't a good idea since now 2g and 3g are not working and I can't switch back to the original baseband since in the menù there's no other option. Any clue?
Edit: flashed your new v3,everything's fine now

Yes...You probably need to apply the basebands of your region when you install CM roms.
You can do that in Androidiani 3.3 Open Recovery, on the menu "Change baseband"

Ahh OK so it has got to do with applying the basebands to my region.
I have seen this option in Open Recovery 3.3 . Is there any specific file I need to download or number I need to know before attempting to change my baseband.?
i live in New Zealand.
thanks.

No, you dont need to download additional files. Just go to Androidiani 3.3 and try applying bands until you get coverage. Many of the people apply RTEU and it works. I dont know what is the baseband for your region, but you switch between them and you will find the proper one.
Hope I've been helpful!

If you're with XT use the Brazil bb.

Where abouts in NZ are you? I'm also a Kiwi (Gisborne) and I have no baseband trouble at all on any of the GB ROM's, or any ROM's for that matter. I've never had to mess with the baseband and I move from ShadowMod to Cyan7 all the time as they release new updates.
What baseband did you use? Im having the same problem and I can't get 3g working for the life of me. I think it's a mixture of apn setting and baseband. Im on 2degrees btw.
I need help with this too. I live in Auckland and use Vodafone NZ. Originally, my milestone came installed with Froyo (v2.2) and it was the Europe version I believe......both 2G and 3G works fine on it, however I have problems with the wifi like many people have.
So then I later flashed to the New Zealand v2.1 SBF, and now wifi works fine but I can't get any connection to Vodafone. The reason is basically because Vodafone doesn't support Milestone, only Telecom XT does. However, if I switch the network from 2G to 3G, then I can connect to Vodafone. I can also connect to 2Degrees, I can see all 3 networks (Telecom, Vodafone, 2Degrees) when I'm on 3G and I get about 3/4 bars constant so it's stable.
But when if I switch to 2G, I get completely no bars and can't detect any networks at all. Not a big deal but I wanna use 2G to save battery. When I was using the Europe SBF (the v2.2 Froyo that came pre-installed with the Milestone), I was able to use 2G no problem.
Anyway, I think a simple baseband change should be fine, but I'm not sure which one I should use that works well with Vodafone NZ.
The baseband has to match your handset's capability. Xt units lack the Vodafone 900 band, they have 850 instead. Both carriers use 2100 in the CBD. Vodafone has also 2g network that has crap coverage. I'm using my xt set with Vodafone, but there's no point changing the bb as xt ms can't do 900 anyway. Basically get ****ty GPRS except right in town. It's only used as car GPS/stereo so no biggy for me.
but mine isn't originally an XT Milestone, I bought it 2nd hand on Trademe and the original owner of the phone got it from somewhere else. It's just that I flashed the New Zealand v2.1 SBF, which just so happens to be for Telecom since there isn't one for Vodafone......
Plus, it was able to work fine on 2G when I was using the Europe v2.2 (Froyo) SBF, so I don't see why a simple baseband change isn't possible?
Check the exact model number, most of the ones floating in nz are telecom models, no matter what the previous owner was using it with. You can change basebands as much as you want, if it doesn't match your hardware it just won't work. I.e. you will not have 3g outside of main centres. Afaik, 2g is the same on all models.
So, install OR, then one of the cyanogen based roms (it has all nz apns). Boot into or, there's a list of basebands - try till you get one that works.
Have you set your APN setting right?
Sent from my Milestone using XDA App
Cyanogen based roms have all the nz apns, otherwise, you have to put the correct one in.

Does a Xperia TL 30LT at&t work on the T-Mobile LTE band if unlocked and flashed

Hi there guys,
I'm new here and was looking at getting an Sony Xperia TL LT30at from eBay. I have read several threads on installing the LT30p version to this phone. But, the one answer I can't find is will this LT30at to work on the T-Mobile network and also use the LTE band. So to be clear, I want the 3G/4G band (1700/2100) and the LTE band(IV). Can it be done on this phone?? TIA!

ah and i forgot to say this " exclude the baseband when flashing the UK version or lte wont work "
Thanks man. Now, I just have to get the phone! This will be my first modding of a phone.
Ok, got the phone from eBay. Phone is is awesome shape. Did the flash for the UK .140 and it worked perfectly. But, my issue is that when I check my base bands by dialing *#*#7378423#*#* .....I see that I don't have 1700 or 2100. Did I do something wrong? I was thinking should I flash the LT30a file since that has the base bands of 1700 & 2100? (The LT30a phone has the 1700/2100 bands as stated on the white papers)
Thanks
FYI, I did exclude base bands. But, I think it's keeping the AT&T bands and not adding the t-mobile bands of the 1700 and 2100. I do see the LTE IV band for T-mobile.
i don't have UTMS BC4 on my "Working Bands" list.

Your fine, its just the software showing that and ATT does not do that. Also dont flash the LT30a only flash the .140. Keep the baseband from the LT30AT dont flash any Lt30a files
So, will that band magically show up soon or will I have to do something to get it? Thanks

I flashed the phone with only the basebands and it worked. I get everything now. That's why I wasn't seeing UTMS - BC4 when I excluded basebands at first.

yes, if you flash with the new software and include the new baseband it will work.the only thing you will have to do is change the network settings via *#*#4636#*#* and look under....Phone information and the change network settings to LTE.

Also change it to lte/gsm/wcdma instead.

[Q] Euro Baseband for Xperia T LT30p

Hello Friends!!
I have a big problem with my device.
It's a Sony Xperia T( LT30p). The problem is that it does not have support for the band 900 UMTS. And I have problems of coverage in many zones where this band is for that my operator operates in H+.
My device works on GSM850, GSM900, GSM1800, GSM1900, UMTS_BC1, UMTS_BC2, UMTS_BC4, UMTS_BC5, LTE_BC2, LTE_BC4, LTE_BC5 and LTE_BC17.
I need to have UMTS_BC8.
I do not understand how this device may have LTE support when is not a 4G device; and not works on UMTS_BC8 when Sony indicates that it works in the band 900 UMTS.
My firmware is the stock unbranded for Spain, 4.1.2.
My question is if I can solve this problem if i will flashing a correct euro baseband with flashtools. The problem is that I do not find any baseband in file .ftf for Xperia T; thing that if that there is in XDA is the whole compilation for the Xperia Arc S.
I would be very grateful to you if you will helping me to solve this problem.
Another point is that in the menu of selection of band only me there appears USA Band, when there should appear EURO Band.
A Greeting!!!
This is weird
In fact in my phone I have UMTS_BC8 and there are no LTE bands.
Your customization number 1268-8488 seems right (generic Spain), I can't believe your device is working with a wrong baseband which is the one for LT30a or LT30at.
So, just try to flash a complete new firmware with Flashtool.
Go here: http://forum.xda-developers.com/showthread.php?t=2648320
Pick an unbranded one for LT30p from any country and... anyway there's also your 1268-8488 (Unbranded Spain) to choose if you like

I thought that, that flashing new firmware the baseband be changed, but no.
I can change firmware but not the baseband.
I was flashed all tips of versions of Android, 4.0, 4.1, 4.3 (all stock) unbranded Spanish, Italian, European, Vodafone, Yoigo.
Even install it a zip archive Baseband by Recovery of Hybrid based stock, without any effect, I have been unable to modify the baseband of the device.
I bought it on Amazon. I imagine it would unlock bad seller
I think it would be either a software solution to fix the phone after a bad unlock or flash a euro baseband on .ftf with flashtools.

I'm thinking that you might actually have an LT30a/LT30at, which does not have the BC8 band and does have LTE support, and either you or the seller flashed the wrong FTF. I don't know if this is actually possible, but if it is the case, you should check under the battery if there is a label that actually shows which model you really have. It's the only thing that makes sense to me, because you're describing an LT30a/LT30at.

mmmm
Its possible.
Maybe they gave me pig in a poke
Or in this case, LT30AT instead of LT30P .
I have no time to open the device and look under the battery, but the sticker off the side.
The model is 12w39, if detachment, put another sticker under PM-0140-BV.
So I conclude that it is very possible that they sold Sony Xperia T LT30at (Sony Mint Amy).
Perfect, I can not use the 900 band HSPA + (BC 8) and nor LTE because in Spain is on the 1800 and 2600 BC 3 and BC 7.
WHILE 2100 can continue to use the UMTS settle me.
Curious that LT30p firmware is going great, really does not give me no type of error.
I will not be forced to claim, as I feel cheated, the box, the firmware and everything was the LT30p.
What a scam.
Thank you very much!.

12w39 is about when the device was made. It says: Year 2012 Week 39 (=september/october 2012)
Pull the same label inside the sim/sd-card door and tell me what's the SI number (abcd-efgh)
Look also at the side behind, it should say LT30p.
I think you can use your warranty anyways.

Should firmware be based on hardware or region?

Hi everyone, I have a quick question regarding Firmware.. I live in south America so I have been using the customized lam firmware which was the default. I'm now moving to Singapore, should I flash the Singapore firmware or continue with this fw? I'm afraid band might not work as well there without the proper fw.. Thanks!
I don't think there's a reason to flash anything. To be sure, check working bands in your phone. You can check that inside Xperia service info; dial *#*#7378423#*#* -> service info -> configuration.
Then ask someone (or Google it) which bands they use in Singapore. If those bands are supported by your phone, you're good to go.
That's what I'd do, anyway.
