Modem flashing - Galaxy S I9000 Q&A, Help & Troubleshooting

Hello everyone. This sure is a terific forum for android resources.
I have a i9000T on Android 2.2.1 and I'm planning to flash it to CM10 Jelly Bean when the next M series firmware is released. I'm comfortable with doing geeky things with computers but not so much on Android phones since I'm pretty new to it and hadn't been exposed to it that much. In the past so far I managed to root the I9000T with CMW to back it up and installed a commandline app on it.
I've done a lot of reading and research on the I9000 but I haven't gotten to any resources explaining how modems work or how one is compatible with another. I'm under the impression that after flashing to CM10 I might have to install the modem or a compatible modem for my i9000T to work. My current baseband shows UBJP9 which doesn't have a lot of useful hits on google. I've found the modem collection at this thread (http://forum.xda-developers.com/showthread.php?t=1870460) but couldn't find the exact match. (How come some on the list have only 3 digits?) My question is then how to figure which ones on the list are compatible with my device, and how to apply the file to the device?
On a side note, how do we decipher the baseband code and figure which other basebands are compatible with one another? The first 2 digits are country code, and the next 3 are modem codes?
If someone would help explain some of those questions or point me to resources to read about those things I greatly appreciate it. Thanks.

Thanks for the info. I came from there initially, and wanted to ask in that thread but wasn't allowed to. I sort of not want to test the modems one by one because being a noob at androids usage I wouldn't be able to recognize if one is better than another. But reading that thread more closely I now know what the last 3 characters mean, although not all of it makes sense (for instance the P in my JP9 doesn't really map to a month).
I think the general tone one could get from that thread is more of like "try and see" and doesn't really answer my curiosities. Also from the discussions one would think that newer versions don't neccesarily mean better. I'm hoping to find more insight on what makes a firmware compatible with another, but the discussions there (or other sources I've come across) doesn't lead that way. The country code on my current modem is for Brazil but it is working in the US. That sort of suggests that the transmission bands the carrier operate on could be more important, and maybe some would suggest to go for modem firmwares in the country where the phone is actually being used. I was hoping to find discussions that tell us what all those firmware are, or what they do (i.e whether a firmware would make the phone work on one specific band or multiple bands, etc..) and things of that nature.

Thanks. So I'll flash to CM10, then flash the modem alone using one of the modem firmwares in the above thread? Is it possible to keep my current modem going from Froyo 2.2.1 to CM10 Jellybean? Ideally I'd like to keep my current modem in CM10 to see how well it works (if it works). Is the modem association separate from the OS, or does the OS already have a specific modem associated with it when the OS was put together? If the latter case, every time we flash CM10 with newer M or nightly builds we'll also need to flash the modem afterward again?
Thank everyone for your input so far. Sorry to throw all those questions out there, but I wish there's some kind of reference to how Androids work so we all can benefit from.

Hi,
I had many of the same questions as you. See my post at

I'll let you know what I find out and maybe you can do same.

iPhone Power User to Android Noob: Few Questions...

Sorry I'm a little noobish when it comes to Androids (trying to come over from an iPhone).
I understand rooting. But... Can you tell me advantages/disadvantages of all these ROMS? Do some have the latest radio firwmare and some don't? I thought I read I could also modify these ROMs as well. I would appreciate some insight. Thanks

You can do anything. If you read the forums you will learn a lot more than any 1 person here could ever teach you in one post. Happy reading.
P.s. posts like this are frowned upon around where when you could have searched.
ROMs are just modified versions of the standard firmware the developers that make them bundle certain apps with them and make some slight changes. IIRC they are all rooted.
I think the radio firmware can be updated seperatly as i downloaded the HTC radio directly from the HTC website.
There is a thread here that tries to chart the differences between builds (the name "rom" is kind of a misnomer).
http://forum.xda-developers.com/showthread.php?t=517506
Also, for community ("hacked"/"rooted") builds, they generally don't include the radio. You would update the radio and bootloader separately. The official builds tend to include radio and or bootloader updates.

This should help you out with any information on Firmwares, its alot better then a stupid chart.
Just do yourself a favor.. Do not Flash before you read the entire thread. Because you may find your new G1 is a brick.
If you want something or want to upgrade SPL or Recovery or Rom Make sure you competely read the thread you may find that other users that have previously flashed that particular item will give feedback.

that link also links to the same "stupid" chart. btw that chart is great for deciding which build suits your needs the best
I was sorta kindling.....
My thread has all the information and MORE. The chart is helpful but you can't get any helpful links with it. My thread has information/my thoughts/ and updates on how to find the newest firmware.

ugh, step 1) read stickies... this does not belong in development
step 2) read through the options you have (basically SRE, UTB, and SuperStock right now) and if you aren't going to take the time to read them, hold off on flashing until you know what you're doing

go for it. things are very solidly organized (there's even a specific section just for asking questions).
there are explanations of what this forum section is for (the development/hacking of android on the captivate and how to use the developments). If you want some advice on what's the general preference, look at general (where I believe this conversation is already happening with a topic titled "UTB vs SRE") or Q&A.
You should also read about the potential ROMs you're looking at (SRE, UTB, SuperStock) in their respective threads. There is no "This is the best ROM that everyone likes so use that" thread because the options are still relatively young and you have to decide which tool you want to use the most.
If you find reading the threads for what the ROM or tools do too difficult, then maybe modifying this device isn't for you right now. There's nothing wrong with asking questions (specifically in the threads of the various tools/ROMs) just place them in the right place. Your question has nothing to do with development, and that's all I'm asking
ok thank you on a side note is there any rom that has everything 100% working

Seriously the potential of anyone really answering your question on here is a joke. Don't get me wrong, but I've seen ppl post things 5 or six times (in Rom or kernel) threads and if they are lucky enough to get a answer they are told to search the forums and when they do they just run into other threads where people are told to guess what...search the forums. So its just a endless cycle until you just forget about it and move onto another ROM or kernel.

To the best of my knowledge, every tool out there has everything working 100%... AOSP isn't out yet (which already has said they're having trouble with bluetooth, camera, GPS, and data) and SuperStock has supposedly spotty wifi and data.
Your two major options right now are SRE and UTB, both of which are only modifications to the stock ROMs so everything is working. SRE provides more options and more customizations and UTB hasn't been updated in a while, though they're both valid options.
Personally, I'd suggest using SRE and going to that thread and reading up on your options

Yes and no.
The ROM on your phone is the official release - all others are dev builds. This includes the captivate ROMs and i9000 ROMs. Newer captivate builds fix a few things, but you lose tethering and maybe a few other things.
The i9000 builds all require the Captivate kernel, so some things don't work right.
Again, you need to read the threads on the different ROMs and decide for yourself.
I think i'm running jh3? I can't remember which. haha.
I lied, I guess i'm running jf6 still... Don't remember that happening.
Personally, I'm running jf6 (stock), rooted, metamorph minimalistic theme (tweaked a little to my personal liking), and adw (to customize even more). I've tried jm2, jm5 (both with samset on top), and jh2. Never tried froyo because I need my phone to work and it has too many known bugs.To me, a rooted, customized, stock ROM is the best because it give you less problems and sideloading through adb is easy. Also tried the lag fixes but other than the Quadrant scores, I couldn't tell too much of a real world difference so I took them off. I never had any GPS issues with jf6 so maybe I'm lucky.

[Q] which official firmware to flash

I have searched for help but could not find it.
I do not know how you work out which of the official roms to put on the phone. I currently have a UK unbranded I9000 with I9000XXJPO on it.
How do I know which rom to flash? Believe it has something to do with the CSC?
I have not flashed one of these but done many HTC HD2.
Do I need I9000XXJVO, CSC = I9000OXAJVO?
CSC is so not important. It's just settings from network provider which you can google yourself. Firstly, you have to search for full ROM which contains three files and a pit file.
Fisrt you need to read post.Try search on forums there are some many post about it.
Basically you need gingerbread.Latest version is XXJVO.
Try search if you have question you can send me PM.
Thanks for the tip on searching. I already said I tried that. There are 5 different roms all released on the same day. 3 of the releases have different CSC codes.
Now I have your answer, that I can flash and of the gingerbread releases and that JVO is the latest, I have my information.
Please remember before telling people to search when they know how to use Google etc, not everyone knows as much as you about this technology. Everyone has to learn somewhere, XDA-Dev is an excellent place to start. So many people on forums are too quick to judge and point out peoples fault. I have a lot of experience with HD2 but could not get my head around 5 separate releases on one day.

Sporadic H/3G/G or Nothing!

Running MyUI Euphoria, absolutely GREAT rom. I'm new to this stuff by the way. When I was at stock, I had no problem with AT&T signal (3g) or wifi anywhere, especially at home. Now, at home (only) I have either G or no bars at all. Cannot connect to wifi anywhere. I love this ROM, but if I have to change to another, I don't mind, but have no idea what would be better than this, or how can I fix this.
And, if I have to change ROMs, do I just flash the new one over this?
Thanks.
What have you tried to fix this? Have you researched your issue by searching? Tried different modems? Your question is not unique, there have been many threads on it, go through the stickies and see what you can find.

I haven't tried anything, hoping to be directed, like I said a noob with this stuff.
But I understand what you mean.
Here's another question, if you don't mind. The nightlies. Do I download those and install for an update, or do they have nothing to do with MyUI Euphoria? Also, when you install a nightly, does it (like any normal update) just write over what you have and install the updates, or do you install it as a new fresh rom?
Appreciate your patience with this lowly grasshopper.

I have no idea. Could you post a link to the ROM thread from Development? I'm not familiar with MyUI Euphoria as a ROM.
It seems like My UI runs has their own nightlies, unfortunately I lack a computer and 1 of the links appears dead other 2 are in French and my mobile browser is having a hard time translating it. Thing is there is no way to know unless you find the nightlies change log and see a commit on your specific issue. It seems to me though that it be easier to just check modems first... Just my 2 cents

I had to test around 10 different modems before finding one that worked on the ROM I am using.
Search for various different modems. With any luck you can find a post from some one in your area who already had good luck with a modem.
Google for "Captivate modem ics" (I can't post links yet...), first result is the one you want. Soggycashew.
Or the other link provided if its not ICS (I don't know anything about that ROM)
Also on the link they have a map with various results using different modems.

New Smartphone and orientations

Hi friends,
I'm planning buy a P990 and one of the first things that i pretend to do is change the rom. It comes with a (stock?) Android 2.2, and there a few questions that i need know:
i need make a normal update to GB for flash or could be directl for roms with 4.x.x?
need change baseband?
need configure google account in Froyo for flash or don't?
thanks for help now,
Dioxx
Hi there,
You can jump directly on GB or ICS (whatever your preference is) without having to configure your Google account on it. There are several ROMs on the Development forum, check them out, read people's feedback and pick the one that suits your needs best.
You can also find a few guides there. I recommend reading tonyp's Baseband guide - it answers pretty much everything related to basebands.
ICS was released officially by LG not long ago, however it can't be considered completely stable yet. If you need something reliable, I recommend Temasek's CM7 (also available at the Development forum).
The best advice I (or anyone here) can give you is: read, read a lot. Spend time investigating and learning about the available ROMs / mods / kernels. Most questions you might have now are already covered, all you need is time and forum's Search function.
Hope that helps you get started!
