First of all I want to salute everyone in the XDA comunity, impresive people.
Well, my question is on the Xperia X8 modem, so it can be modified to work on any UMTS (WCDMA), I far as I know it is possible, some other devices that uses the same SoC can do it even in a service menu [Samsung]. So, why not Xperia X8?
I'm an Engineer, and I have few experience on embedded devices, but there's few information on the Qualcomm MSM7227 so it's hard to tell; it is known that the amss.sin is the microkernel running the radio on the device, wich is in charge of the GSM, GPRS... UMTS, on a ARM9. I did flash the amss file from a E15a on my device, and though the service menu (on 2.1 Stock) I've found that the working bands were the same as the E15a and not E15i (My phone is a E15i I'm in Colombia Carrier uses 1900Mhz) BUT there was not response in WCDMA mode Only. I hope E15a and E15i are the same in harware. Maybe it is also possible that SEUS can flash the firmwares for the device we need/want but I'm not acquainted withs SEUS. So maybe it is needed to change something else, it is possible to have access to all the memory map, everything is men made, can be hacked/mod.
So, hopefully there is chance to do this.
[I did search on XDA for the Xperia X8 related topics, but did not found specific information, that's why I started this thread.]

The E15a / E15i Xperia X8 is exactly the same hardware (same goes for the E16's (W8) ... they are of the same hardware but ship with a slightly different ROM (known as "Walkman")).
You can actually turn a E15i into a E15a by simply flashing the E15a baseband (and the other way around). Inside the baseband are the required files who configure the GSM/UMTS radio for the correct frequencies used to communicate with the mobile network (read: the towers).
So far no one actually ever tried to patch-up a "generic" baseband which would work on all supported mobile networks ... if you feel fancy enough you can try.
Thank you for your answer, I did flash the E15a Baseband so I did get the "Working Bands" on the Service Menu UMTS_BC1, UMTS_BC2, UMTS_BC5 (E15a) (Stock Kernel) but, still nothing on the actual signal, nothing working with WCDMA only, and the phone still says "Model E15i" on the device information. I was looking at my build.prop file, and there is something about Model and hsxpa:
[I'm using now nAa Kernel 10, but can not find a way to see if I still have the correct E15a modem firmware]
ro.product.model=E15i
ro.product.name=E15i
something about LT15i
ro.ril.hsxpa=2
ro.ril.gprsclass=10
ro.ril.hsupa.category=5
It is good news to hear that all of them are the same, in hardware, so we all still have the chance to use the bands we need.
I hope someone could figure out how to make this work, I'm not an expert on Android, but still curious.
Thanks again.
I only know that switching the baseband and getting a GSM/2G/3G signal works at least with the Stock 2.1 ROMs. I can't speak for custom Kernels and/or custom ROMs (since you at least flashed a custom Kernel).
Looking at the 3G settings you can select GSM, WCMA and WCDMA; so the three are supported in both basebands.
Anyhow ... flashing the custom Kernel should only replace the Kernel binary - it doesn't change anything else of the the baseband (Stock Kernel+Baseband FTF == ~26MB, custom Kernel FTF == ~7MB, naked Stock Kernel == ~7MB).
As for the hardware ... allow me to correct myself as I wasn't accurate ...
While the devices are all of the same hardware there are two minor differences (applies to W8/X8 i/a):
1. Depending on the region where you bought the phone you may either get a touchscreen with a Synaptics digitizer or a Cypress digitizer. That's just a suble difference.
2. Devices built at 11W29 and later have a revised chipset where the security holes the boot loader unlock uses are closed - trying to unlock the boot loader on the affected devices will cause a hard brick at a 99% probability (I only know of 3-4 post 11W29 devices that still worked after a boot loader unlock).
That's about it ...
I think your best bet would be to try and talk with nobodyAtall by PM or to conduct your test by using the Stock baseband/Kernel to work out that you get a signal/connection.

Okay I got a question about Basebands, I have the UK version of the Milestone But I live in the states, In Iowa. Is there a different baseband I should be using? Cause I've never seen a baseband in any of the lists I've found for north America or anything like that.
Argentina-Personal.zip
Brazil.zip
Canada.zip
French.zip
Germany.zip
Isreal-Celcomm.zip
Italy.zip
Singapore.zip
Telus.zip
Thai.zip
Venezuela-Movilnet.zip
That's about all I've seen for basebands. If someone could clear this up for what the baseband actually does and what I SHOULD have that'd be great thanks. You can see my current Baseband in my signature.
I guess baseband is more like, what fits you best.
If i'm wrong please correct me, but if you'r getting good reception its all good.
I also am in Iowa-Sioux City, and have found that the Singapore basebands are the only ones that work here, tried them all after I flashed a rom that changed my baseband. I believe that the baseband sets thew acctual frequencys that your phone uses,there are many in each of the bands that are avaible.

too bad for me
i think i lost my baseband?
it shows me a "no service" my milestone cant detect my simcard's network
..... help please...
hey, where could i found this Venezuela-Movilnet.zip baseband? i really want this to use my 3g network on my xt720
There are two things about baseband: the baseband software and baseband configuration.
Baseband software (I don't know much about this, sorry...) may be in your system rom somewhere and you flash it with a zip file. In Eclair you'll see software and confugiration version in "About" page, but since 2.2(?) you'll only be able to see software version. I don't think this differs much for each people. You can find the latest(?) here:
code.google.com/p/cyanogenmod4milestone/downloads/detail?name=update-bpsw-MSG39UPEU_A1.19_0.90-I4.zip
(sorry, I couldn't post outside links...)
Baseband configuration (located in /system/etc/motorola/bp_nvm_default/), according to my understanding, is to interpret GSM signal to something your phone can read. This is more like what fits you best. For example, with a baseband config from stock 2.1 rom my phone works well in the basement, but with another, it may show "no carrier".
Hello All.
I had a small talk with DoomLord about flashing base-bands over the phone and the difference it would make for your phone so have decided to make the information that I got available for the public here so that no one else has to go to the same hassle I did Googling for all the stuff.
I am a power user of Android. But completely unbeknownst to the development side of the OS. So if I make any mistakes, I request you to point them out to me and I will make the necessary corrections.
So what exactly is a baseband ?!
Inside of your cellphone, there is a chip embedded that enables it to communicate with your carrier's transmission towers. This chip is known as a "baseband processor" and it is responsible for signal processing and realtime radio transmission operation. (Got that bit from WikiPedia)
The baseband is actually a piece of software that instructs that processor on what frequencies to operate on.
Kind of like a driver for any hardware that you might install on your computer.
So any gain in the level of harmony between the hardware and software that make data transmission happen on your phone (GSM/DATA) is only going to benefit the phone's performance. ( READ battery life, signal reception, etc.)
Also, each baseband has it's corresponding libraries which also need to be provided for it to be working optimally.
So that's that for the theory part.
I'm open to corrections. If anyone can point them out, I will be happy to edit the post. But I had a lot of trouble trying to understand WHY I should flash a particular baseband and what difference it will make.
Currently, at XDA we have baseband patches for baseband -36 and -64 available.
So as per your ROM requirements, it would be better to flash any of these base-bands onto your phone with their corresponding libraries.
Which brings us to the next part.
ACTUALLY flashing the baseband.
Pretty simple process actually.
But from what I know, you will need a rooted phone with an unlocked bootloader to do this. (!! Not sure !! )
And a custom recovery (Clockwork MOD) that can allow you flash .zip to NAND.
EDIT : You just "NEED" root. (Thanks Flo95)
Please follow post 2 for further info on how to do it without root.
My ARC S is rooted and has an unlocked bootloader.
So all that you need to do now is download the following :
1.Flashtool.
2.Baseband that you require.
3.Corresponsing baseband libraries
I will be posting more on this with screenshots so that everyone can enjoy the same benefits that I have currently after using my phone on -36 baseband and using the corresponding patches.
Credits to DoomLord (For awesome DOOM Kernel) and Iridaki (For baseband patches). If there is anyone else to credit, please do point and I will acknowledge the same here.
I invite inputs from other experienced XDA members to provide more technical Know-how on why this is necessary. Sadly, there is insufficient material right now on this topic here.
Thanks.
EDIT :
Lets share a list of working Basebands in various areas :
For eg. :
Gujarat, India : 36 works fine on Vodafone 3G
64 works fine on Vodafone 3G and Airtel.
NSW Australia (on the Optus network) : Baseband 36 tested to be working great
Finland:
-64 works great for Sonera / Saunalahti / Elisa / DNA
-36 drops connection alot for Saunalahti / Elisa
Croatia
baseband 56 works great in Croatia
You can point to the baseband working for you and your location and I will update the post accordingly.
Thanks
Please click the "THANKS" button if you feel you've benefited from the info !
You can flash basebands without an unlocked bootloader, as it happens when "normal" users update their devices the official way without need of an unlocked bl.
You can get recovery with SE Extreme Tweaker on locked bootloader, too.
Only thing you need is root.
But for kernel awesomeness I'd definitly recommend to unlock the device.

I think this is a great idea to discuss what basebands work best in what areas, it will certainly help a lot of people make the right (and informed decision).
To start off, I am in NSW Australia (on the Optus network) and I have found that the ideal baseband for me is .36 - All the other ones work fine of course but the .36 offers best/optimum battery and radio output for everyday use (with the latest DooMKernel of course!)
Hi, Im from the Philippines and wondering what baseband suits for my Arc S?

Yes there is a way to flash the baseband without Flashtool, but we wont publish it for now, since it's not working reliable on me. For theorie its working like an SE fota update. Which uses binary diff and flashes the diffs to the corresponding areas. This way you could flash all partitions. But this is only theory for now, because with flashtool we have a better way which is very very safe. Even if flashtool fails the phone can be restored everytime. Via FOTA you can really brick it forever
@All asking for which baseband fits best:
Please please DON'T start flashing basebands without thinking about now.
Normally ALWAYS use the baseband which comes with the ROM! For example SE always has the corresponding baseband included. This baseband fits the android libs it comes with.
On custom Roms please read what the developer of the customRom telly you. If he/she has developed the Rom for specific baseband libs.
All other things like baseband patches are tested and developed by other developers which know what they are doing. So if you use such a patch ALWAYS read the manual and the requirements. Because it CAN happen that it is NOT possible to use a GB baseband on a ICS rom and vice versa. The is a little more than "just" libs and firmware. Also the java part framework/base/com/java/internal/telephony....
has to fit the baseband (SE is very special here).
So i hope now you all understand. Please please please leave the decision which baseband is best and which is working to the devs who know what they are doing!!!!!! Don't come here and tell "i tried baeband xxxxx now my phone randomly disconnects data/voice/..."
Thanks
I'm in Victoria, Australia on the Telstra network. Does anyone know which is the optimal baseband for me to use?
Cheers.

Baseband 006 - kernel 2.0.2.A.0.24
Baseband 015 - kernel 2.1.1.A.0.6
X8a - E15a

Baseband 015 - kernel 2.1.1.A.0.6
I took this from Se xperiax blogspot and my cell phone is X8i- E15i with baseband 015 - kernel 2.1.1.A.0.6. However, doens't work, so i want put baseband 06 - kernel 2.0.2.A.0.24. But How i do it?

Hey guys, i changed my baseband to all x8 versions, e15a, e15i, 006, 015. But my 3g still unworking. So, now i want to change my version, i use 2.1.1.A.0.6 and want to get back to 2.0.2.A.0.24
How to do it?
Then the problem might be from your provider, the only way to get back to that firmware is flashtool, but i dont know where to get that particular one.

Hello all, I'm moving over here from the Atrix section (boo motofail) and I'm a little confused by the amount of phones that seem to be crammed into one area here, the atrix only had 2 versions and after a while devs were able to patch the kernel to work on both, so any rom worked on any phone.
Here it seems there are many versions of essentially the same phone with different and incompatible roms for each.
Perhaps someone could fill me in on the difference or meaning of LT29/LT30A/LT30P, T TL TX ect ect.
I have a Bell Xperia T, in the about phone section it says LT30A, Can I use any Xperia T rom? Just LT30 roms? Or just LT30A roms?
Thanks.
All lt30 variations I believe you can flash through flashtool. Really just different model numbers based on location.

What model do you have??
You upgraded by PC Companion or by flashtool?? Maybe the baseband is incorrect and the phone don't have signal, maybe your carrier use two band and not both are in all coverage.

Initially upgraded to .434 using flashtool, then .67 by OTA. By baseband do u mean 2g and 3g? Cos I don't get any form of signal at all.
Hi there, I have had the same problem: after updating the XZ to 4.2.2 (2.67 over OTA) the signal dropped instantly. Therefore I had to send it back Sony Care. They fixed it. The update has overwritten a different smallband/baseband-version above the other one, just as I suspected. I bet you can flash it yourself (your an XDA user..) instead of waiting 2 weeks or more. If you don't know how it works and you've absolutely no experience with flashing, just send it back to Sony care.
I think the easiest way is to flash a different (older) baseband-version on your XZ, reboot/factory reset and see if it works. The second method is to try downgrading the software to .244 INCLUDING the baseband-version, then update it by flashing the XZ to 2.67 while EXCLUDING the baseband-version. The third option is to re-flash (with flashtool) the 2.67 update but a different version (GLOBAL).
My phone details:
Modelnumber: C6603
Android-version: 4.2.2
Smallbandversion: 9x15A-ACEFWMAZQ-30110068-44
Kernelversion: 3.4.0g43a9ba9
Buildnumber: 10.3.1.A.2.67
Altough your smallband/baseband may differ from mine. Therefore, please find your own software-version. I'm using:

I have a similar situation in the case of C6603, in my carrier sometimes I have 2G signal but never 3G and other times no signal. In the case of OTA or PC Companion updates, sometimes upgrade to diferent model or carrier, I have a friend that upgrade his Xperia Arc by PC Companion but with the uncarrier firmware. Maybe this is your case, the OTA firmware don't well upgrade your base band.
In this case I suppose that you can flash only the baseband by Flashtool, but be carreful that the firmware was made for your Xperia Z (C6603, C6602, C6606).
