[Q] Can someone explain to me the basebands, ROMS, and f/w files? - XPERIA X10 Q&A, Help & Troubleshooting

Ok so I have the x10i
Baseband is 2.1.54
Build number is 2.1.A.0.435
What do they mean ? and how do these affect roms, ( are roms specific to certain basebands or build numbers?)
and would Cyanogen CM7.0 RC4 v013 Gingerbread 2.3.3 work on my phone?
Thanks for you help this is a one time question and I plan to understand this stuff once and for all

Basebrand basically just means what type of radio signal I believe. Build number is the firmware that you have. Usually ROMS require a certain type of basebrand, so always look for it before you flash anything. CM 7 wouldn't work on your phone because you are running .54 basebrand and it runs on .52 basebrand. If you do not have the correct basebrand you can have a bootloop in which your phone basically doesnt function at all. If you fairly new to this i suggest you flash a stable ROM such as CM6.1.3 by wolfbreak or Freex10 Rom by Z.(both work with .54 basebrand) CM7 is too unstable for a new user to be testing

Alright thanks!
I will check out those roms
So ROMs can work on any Firmware version? but they are only working for certain basebands?

There's normally a list of requirements on the ROM thread that you want to flash. Should normally work if you have the correct basebrand though. =)

Thanks!

Baseband - it is concerned with the cellular reception , signal strength, data etc. The newer the baseband the better reception.
Each rom works on a specific baseband just like posted above.

[Q] 2.1.1.A.0.6 Rogers rom on ATT?

Has anyone put the new Rogers rom on a locked ATT unit?
Any market problems?
Any problems removing Rogers apps?
I THINK want to go to one of the custom roms but I'm only on Baseband 2.0.46
and I don't have Dual Touch installed. But it seems that I'm required to update to the higher bb at least, and though I see a BB update only thread, it's unclear if all basebands are compatible with all SE 2.1 update-1. And then I would still have to update to dual touch prior to installing a custom rom.
Since these are two independent flash requirements, and it seems that I have to update to some rom higher than 504 anyway, so I was wondering if I could just go to the Rogers one.... getting dual touch and a higher baseband right off the bat in an official package in one shot, and check it out prior to deciding to move on.
Different basebands work with different firmwares and kernels. You can mix and match, to some degree (for instance, .55 baseband works with .435 or 2.1.1.A.0.6 FW), but there's really no reason to.
I own an AT&T X10a, and I always use the X10i Global Generic firmwares. All the features without all the crap.
Check out the link in my signature for an optimized version of the .435 firmware (dualtouch, etc). Follow the instructions, there's a file for flashing the new kernel and baseband on there.
Good luck!

But even your firmware says I have to flashtool a higher baseband to get it work prior. (Shouldn't you update your screen shots, you show bb 2.0.46 when you really mean 2.0.54) Though what you've put together is very interesting. Do you still have all the SE apps, too, in the collection of applications? (Just asking, I know they have apk's available.)
I'm just trying to avoid flashing multiple times now*, do a straight 2.1.1.A.0.6 update and flash only once and get higher baseband, dual touch and whatever other tweaks there are which don't require flashing. There's no LAM/NAM generic of this version yet?
*flashtool for me a PITA, because I don't have VISTA/Win7 computers generally available and it works better on that than XP which is problematic due to the SE usb drivers which sometimes freeze it in flash mode. I am getting a decent tax refund, I suppose it's time to upgrade to sandybridge and Win7 (since the first SP is out) before they announce Win8.

help needed installing ROM

I've seen many roms uploaded here but do not know if they would work on my X10.
I have rooted it. Busybox and Xrecovery installed..
Firmware version : 2.1 update 1
baseband version : 2.0.46
Kernal version : 2.6.29
Build number : 2.0.A.504
I'm new to all of this so any help would be appreciated
I wanted to install this.. would it work on mine?
http://forum.xda-developers.com/showthread.php?t=865580
I think that ROM requires the 2.0.2.A.0.24 build number. You can flash the build firmware using flashtool. And then you can install this ROM with xRecovery I believe.
I've heard you can lose your 3g conenction, is this true? I'm on o2 in the UK.. does this matter?
You can lose your signals if you don't flash the correct baseband I believe.
ALWAYS make a backup of your original ROM before installing a new one, so that if any problem occurs or if youre unsatisfied with the ROM, you can revert back to the old one.

for what are baseband patches for ?

I could not find for what are baseband patches for ?
Thanx
It is basically done so that you don't have to keep changing basebands whenever you flash different ROMs which work on different basebands than which you currently are on.
If, for example, you are on baseband 54/55/58 and the ROM you wish to apply works only on baseband 52, you can flash the ROM and then apply the baseband patch to make the ROM work perfectly for you. Likewise, if you are on baseband 49/52 and the ROM you wish to flash works only on basebands 54 and above, you can flash the ROM and then the baseband patch.
how can I apply the baseband patch?
You first flash the ROM, then in xRecovery, flash the baseband patch.

[Q] Baseband...?

Okay, I have baseband "V07u Mar-23-2009" But people keep talking about "v10" and "v20" so I have no idea what baseband I'm on, I've previously flashed sonygenmod and CM7 from Mik_OS on here with no issues...
So, am I on the new or old baseband... if I'm on the old, should I upgrade to the new one?
you are on old baseband v10, if you want to use official gingerbread 2.3.3 or lupohirps ics etc then flash new baseband.
(baseband will be mentioned in rom thread)

what wud the "baseband version" be displayed in settings once we flash new baseband??
as with old BB it displays--->V07u Mar-23-2009
with new BB-------> ???
No matter if you are on new or old baseband, that field will always display the same text.
If your last stock ROM was a Froyo one (v10x), then you're on old baseband. If your last stock ROM was a Gingerbread one (v20x), then you're on new baseband. That simple.
But, since you were running the mik_os port just fine, then for sure you're on old baseband.

New baseband no signal problem

I just updated to new baseband, I flashed several NewBB roms, and there is no signal for any of them. When I first finished updating my new baseband, I had signal and data on the stock t-mobile rom. I checked settings, and the android version is 2.3.7 but the baseband version is unknown. If I can't find a solution to this, can someone give me a flashable zip version of t-mobile stock rom, (or any other stock rom) Please help, because I was so excited to explore newbb roms.
