Hello, I was just wondering if someone could tell me exactly what a Baseband is. I mean I know that some roms require certain ones, but other than that I have no clue what it is. I would be very thankful if someone could get back to me on this.
A baseband is what controls the radio of the phone, and what frequencies it uses. It controls calls, gps, 3g/hspa+, texting, etc...
Thank you that make perfect since. I just wanted to make sure.

Hi Everyone...
I got my son a US Cellular PPC6800 (Titan)... It has on it now :
Rom Version 2.17.573.0
Rom Date 7/1/08
Radio 1.69.00
Hardware Version 0003
PRI 1.31_027
After some reading here, it seems I need a diffrent radio to get the GPS to work... my issue is I spent all day yesterday setting up the phone for my son, just how he would like it... I would hate to have to re-do it all just ot enable the GPS... Could I just update the radio and keep the rest just how it is? or wouldnt; that work... I don;t even need the phone itself to work as a phone as I will be using it as a skype phone... I just need the WiFi, GPS, and bluetooth... Thank you in advance for you advice
No your rom or os is not compatible with a gps radio. You would have to install a custom rom and then a compatible gps radio to enable it. You will lose all settings and programs when do this change.
You'll have to flash a new radio and then a new rom, the one you currently have will have to be overwritten.

Hope this helps!
Thanks for your advice everyone... I got a new radio (3.35.04) and rom (RMcarrierlessTitanV1.1Light).. I was most like the standard 6.1 stockI was used to and had known good software for.. After doing LOTS of reading here, there, and everywhere today I was able to get the GPS to work as well with TomTom... Learning qPST was nice though.. I was easily able to change the banner to say "Skype" instead of US Cellular,Sprint, or any other carrier.. I thought that would be a nice touch as this will only be used as a Skype phone anyways...
The only other issue I am having, is when justhte phone is turned off it is reporting it isin airplane mode in certian programs (TomTom for example) and I have to turn on the phones radio to get it to work... Any suggestions? I am not putting it in aitplane mode.. and still have WiFi on at that point.. (although turning hte phone off sometimes effects that too it seems).. I am trying to get it to work well with the phone off to save battery as WiFi will be on most of the time it is in use... Thanks in advance..
Does anyone know what advantages (if any) the new radio has over the old radio? An official/leaked/speculative changelog from HTC or some other expert? Anything?
For example, are there some known issues with the old radio that the new radio fixes? What are they? Does the new radio improve the performance if the device in some way (battery usage, CPU/memory usage, etc)? Is it simply the end-of-life for the original Sapphire radio and they want us to be using the Hero one from a future support perspective?
The basic question I am asking is: why is there a new radio version and what makes it so special?
I've done some reading today and I realise that certain custom ROMs require the radio to either be old or new, so obviously you have to have a radio that matches what your ROM is expecting. I'm not asking about that.
I have the same question. Im not sure if downgrading my radio will cause me to lose some reception or anything.
The new radio/spl combo mostly change how the phone's internal storage is allocated to different partitions - system vs. userdata vs. cache. Without it it's hard to fit the system files of a sense rom on the system partition.
I do seem to get better gsm/3g reception on the new radio though, too - but YMMV.
Do you think it is worth it to downgrade? The only reason I am thinking to downgrade is because it looks like there are better roms for the old radio, specifically the CM5 ports, like the one by alan.
Any more input?
i downgraded to run cm5.07-stable (not alan's "version" though, i just installed cm+gapps+bcrook+o/c710). my gf's phone is still running new radio so i put the NR version of 5.07-stable on it and tbh i can't tell the difference without really poking around in there.
also, i notice that now i'm running old radio again i seem to have more issues with the phone not picking up 3g in areas i know there's 3g until i cycle aeroplane mode. i assume this is radio related and that it's a real phenomenon and that i'm not just imagining it...
but yeah, i think if you're already on NR and aren't sure, i'd try the NR CM5.07 version which i'm sure will soon be replaced by 5.08-t1 at some point. that said, using the radio changer tool is so freaking easy that it makes bricking virtually impossible so i guess you can't lose either way...

okay i have some issue here. after upgrade rom it seem i cant send mms.
is it because of the radio version?
As what i know radio can be specified whether to use GSM or CDMA reception.
not all country use GSM or CDMA as their default reception.
so is that because i use wrong radio version?
how can i know or found the right radio version, for example for GSM?
anyone here have clue...?
The radio version doesn't affect the phone's ability to send MMS. The Magic only works on GSM/UMTS - flashing a CDMA radio would probably brick your phone.
You probably messed up your settings. Call your provider.
i've been trying to find this answer - but does old radio with Froyo have a working camera? I know new radio doesn't. When I look at Froyo roms with 3.22 radio they don't mention if camera works or not.
Does anyone know? Thanks.

Yes they do, the froyo roms for the 3.22 radio do, but it's really not because of the radio, its the kernel that their using for that radio for froyo. The kernel has some good advantages if im correct but it also has its cons.. Correct me if im wrong.

thanks kein for your answer.
but then when i try dialing *#*#4636#*#* and find phone info, and go to the "set preffered network type" it is always pick "WCDMA preffered" as default. i know that magic only use GSM, then i choose GSM only, but when i try to set up 3G on my APN list, the phone goes back to WCDMA as default.
so my guess is if i want to use 2G network, then choose GSM.
otherwise, WCDMA as default for 3G.
but im not sure by sending/receiving MMS use which network (GSM/WCDMA).
any clue?
It should be WCDMA (same thing as 3G or UMTS) if you provider has 3G. It doesn't matter if you use GSM or 3G when you're sending an MMS, as long as you the right APN settings.
So, impressions?
I am actually finding that my phone is less likely to find my router now and it seems to get less signal.
I even changed the registry setting to have it run on an "N" network...still des not sem as strong. Maybe I am being overly sensitive.
Maybe I just need to let it settle in?
Anyone else finding this?
(radio 2.15.40.14)
I haven't had any problems with the new radio. If anything, I've been getting better WiFi reception in my house and the call quality is markedly better. How long have you had the new ROM on your phone? Usually it takes 2 to 3 days based on my experience for everything to settle in. Are you running just the new radio or the new 3.14 ROM?
When was the last time you reset your router? When my signal gets a little sketchy, I'll reset my router and the signal will return to it's former glory.
I literally loaded the new ROM last night.
As you note, it does seem to take a few days to have everything settle so...I shall be patient.
I was one of those who had veritably no problems with the phone sinc eI bought it save for the texting lag.
I am excited to see if this all smoothes out.
Spent a couple of hours doing my registry tweaks and what not last night.
disappointed that they did not change the calendar to allow more options to snooze and that I had to change the registry for that.
Other than that, thus far, I see little other change save for what I noted initially.
Im pretty sure the radio rom has nothing to do with WiFi, bluetooth, or GPS for that matter. AFAIK the radio rom only affects the cellular radio/modem in the phone.

I concur... The new radio is working the exact same for me as the stock radio on 2.13.
That statement is actually not entirely true. The radio controls not only the cellular radio and modem, but also the GPS, WiFi, Camera and backlight of all things. TONS of stuff goes through the radio ROM, which is why having the correct one is a must.

Good to know! Thanks.
Basically im looking to replace the rom on the stock fascinate right now with a wifi only rom with a radio that also pretty much uses wifi only, i dont want to just turn it on and not activate i want to use this as a full mp3 player with wifi only no bars across the top for cell service nothing like that.....Is their a way that someone has some info on how to compile this and or a preexisting rom with these capabilities. I for one like my device alot but its time to upgrade and i would like to continue to use it as a mp player. much appreciated
djp952 is working on one; modding his version of the stock rom to wifi only. http://forum.xda-developers.com/showthread.php?t=1278838&page=76
I'd like to know what would happen if I took a dremel tool and drilled a hole into my cell radio chip. Very carefully so that I didn't damage anything else. With the exception of the phone not being able to connect to the cell network, would the phone still work as normal??
I'm not doing anything illegal but I'm old and I still believe in the constitution and the right to privacy. And since I cannot depend on my government to do the right thing I would like to see what I can do to ensure I'm not "big data'd".
Destroying the cell radio would be my first choice - no doubts at all that my data isn't leaking via the cell network at that point. If that is not possible does anybody have any other ideas of how to lock down the cell radio completely??
Thanks for you help!

Hi Mrktmind
Sorry if I'm missing something here but ... your first option shouldn't be "Airplane Mode" ?
Nice regards.
.
Thank you for your reply Kdio.
My goal is/was to absolutely ensure that no voice/data is possible over cellular network. I'm guessing Airplane Mode is a function of the Android OS and thus would not effect the baseband firmware. Which is what (another guess) is being used to turn on your microphone remotely/covertly even with the phone turned off. I also want to leave intact the wi fi abilities of the phone.
I have since done some research and realized my knowledge of phone hardware may be numerous years old! Not as simple as locating a Cellular chip and disabling it. Now there are modem chips (some with GPS &wifi radios built in), baseband processors, wifi radios, etc. etc. I will keep researching but it is likely to take me a long while to get to where I want to be as I have very little time anymore. Which is why I was hoping a fellow XDA member might already know the answer. Or at least share with me the right direction in which to search.
Some (mostly younger) might wonder if it is worth this much effort just to keep my data and voice regarding totally legal things private. I would plead with those people to study history and learn what happens when people no longer have privacy or anonymity.
