Question about baseband.

Changing my baseband can give me signal trouble in certain zones of my city?
I've been having this kind of troubles and its like i can't call or i can't use internet.
In order to upgrade to 2.2 i had to change my baseband from 06 to 015, but the troubles didn't come right away. I've been having this issues for a couple of days, and when they begun, i got this weird message about "SIM network unlock pin".
plz help 8(

i believe you get sim network unlock pin when you put a sim card form another network in to a network locked phone, i would try a repair from SE's pc companion
http://www.sonyericsson.com/cws/sup...ed/pccompanion/1.689743/xperiax10?cc=gb&lc=en
that's the link if you don't have it already.
if that doesn't work you could try another sim card or take it back to the shop were you got it from.

Thats the weird part because i never changed my own sim card.
Try to repair what using pc companion?

You changed baseband via flashtool, didn't you? Well, basebands are compilation and version dependant. This means that you need to flash baseband that is compatible with your ROM version (in case of 015 it should probably be at least 2.1.1.A.0.6) and with your device, namely E15a or E15i.

I flashed the rom too.
The problem is that i don't really understand what baseband is. So i'm asking if flashing baseband (paired with the correct rom version) can give me network problems.

Baseband is the subsystem of the phone that controls radio communications.
Network problems you have if only you have flashed E15i's baseband version on an E15a (or the opposite). Correct me if I'm wrong..

I think it's the same.

Thanks. I solved the problem.
I flashed and e15i firmware, so i was having trouble with zones using the 2100 band that is not used in the e15i.
To fix it, i used the customization number method that is posted here using this sony number 1243-9502.
Thanks for your help.

Fellow TELUS defy user here.
The answer: No, at least not at this time.
But, you can use most roms and sbfs AS LONG AS THEY ARE ROOTABLE.
This is because you will need the basebandswitcher tool (search that up)
for most roms to get proper cell service.
If you start flashing roms and sbfs, it is helpful to use the China ME722 1.10 baseband or other basebands with frequency 850/1900/2100 I think.
DONT USE ANY T-MOBILE USA BASEBANDS, YOU WILL GET ROAMING.
That's all.

This is the baseband I'm using - works perfectly.
Incidentally, if you're keen on trying the new CM9 builds, the baseband switcher is built in to the "settings" screen under "Advanced".

[Q] DEFY without signal after brick! PLEASE HELP ME!

hi, first i'll introduce myself..
I'm Lucas Lo Faro, from Buenos Aires, Argentina, I'm a java developer and an Android fan.
i think i'm having a problem with the baseband in my defy plus.
i use to have a defy (with froyo 2.2) and now a i have a defy plus with 2.3.4 and accidentally downgraded it to froyo 2.2 when i flashed the standart sbf of my old phone..
so i read a lot here and finally flashed the famous chinese firmware (2.3.6) to unbrick it..
and then i installed the MS2Ginger 4.0 rom but i cannot get any signal..
My issue is:
when i use the baseband switcher v4.0 i get this error:
"unable to detect your baseband configuration, it's possibly damaged. reset to default?"
so i renamed this directory: system/etc/motorola/bp_nvm_default
(as i read here: http://forum.xda-developers.com/showthread.php?t=1203297)
and used the baseband switcher v4.1 as i read in a post here.. but it still doesn't work..
any ideas?
please help meeee!
thx in advance..
i'm in Argentina and my service provider is Personal..
i don´t know what to do..
i thought it may be some rom incompatibility but it seems i cannot change the rom anymore.. because it would brick again..
thank you!

Stock Sbf
Try flashing the stock sbf again. Then root it, and flash a custom rom..maybe it'll work then

Have you tried to select "Claro" instead of "Personal" yet? remember the baseband switcher doesn't work if you select Personal.

I think I have this problem too after I tried (unsuccessfully) to root my phone. Now I can only get some networks (Tmobile & Orange) but not my network (Talkmobile, which piggybacks Vodafone). I've been googling around about this for a while and I think it may be that I need to cahange my baseband. Current ver is EPU93_U_00.60.03. But I don't know how to do this. Any help to a noobe would be much appreciated...

You could try with Baseband Switcher 4, and select your baseband...Then you have to set the APN.
