I've only recently started messing around with flashing customs ROMs and kernels, using my previous phone (HTC Aria) as the tester unit. I'm pretty sure I've got a hang of the process, but I do have one thing that I'm still a little unsure about.
Since I have the i9020a model of the phone, which uses the AT&T radio, would I just have to flash a crespo ROM (GSM) and then an AT&T radio file afterward to ensure that I'll have mobile data?
I have a feeling that this should work fine, but I'm just a little worried since all customs ROMs for the Nexus S are based on crespo, which contains the different radio.
Any advice would be greatly appreciated. :fingers-crossed:

You don't need to reflash the radio. Leave it as-is.
Custom roms don't contain any radio, and the i9020a and i9020t are both "crespo". Crespo4g is the SPH-D720, model offered for/by Sprint.
yep..
nothing to worry...
i9023 and i9020a and i9020t are using the same ROM i guess (I'm using i9023, the international version)
D720 and M200 are using different ROM (my friend using M200 [which is korea version] and try to flash crespo rom (i9023) and got bootloop, LOL)
as long as the ROM said tested with i9023 or i9020t, I think it is OK to flash it to your device (i9020a)
as polobunny said, most Custom ROM are not include any radio, so it safe
Ah, okay. So custom ROMs don't include radio files, but the official OTA's from Google do?
I ask this because I remember the 4.1 update working on T-Mobile Nexus S's while the AT&T model required flashing the radio afterward.

Some OTA do, not all of them.
And that's a silly way to do it when you can manually flash each portion the rom/OTA, but who am I to judge? That was only to circumvent the fact the OTA wasn't out for the i9020a but was out for the i9020t.

Hello I am pretty new to the whole android rooting/ROM world.
I flashed the Golden Eye ROM and everything works great except the lte. I only get the hspa+ for some reason. Do I need to find a different radio?
I attached a screenshot.
Thanks
I've got Rogers SGH-I337M as well, but with a kernel of:
3.4.0-talexop-1.3+
And seem to be getting 4G...
Maybe the kernel needs to be different?
Did you flash the kernel from the 'For Canadian i337M users, how to install GE13/14' instructions? I didn't... I just flashed the ROM and then the 'Fix & BuildProp' fix...
Hello everyone
I wanted to ask you a question about my device's baseband.
Currently I'm on CyanogenMod rom version 11, which I installed via the installer (since it looked so fast and easy).
I moved to CM about 2 months ago from the BTU version of baseband I9505XXUEMK8.
I do not have any reception problems but I saw since this baseband version there went out many other versions (including the new baseband version for the leaked Kitkat).
I do not want to have future problems and I feel "guilty" on being on an older baseband version so my question is when do I need to change the baseband version? Only if I have reception problems or in other cases, too? And in which cases?
Thanks in advance
If everything is working fine then there is no need to change. Usually people would change if their network releases a new modem as it's better to be on the recommended modem used in the original firmware by your specific network or if people are having signal issues. All models work regardless of rom. I've flashed many modems and all have worked fine find the right one and stick to it.

So as I said, I'm on I9505XXUEMK8 modem almost 3 months (from the moment it was released for BTU, but I'm from Israel not England).
As far as I understood, I can stay on that rom as long as I don't have any problems right?
Correct. You'll be fine with your current set up.

I am beginner in this rooting field.. And with less knowledge I now am attracted towards flashing different rom on my phone since I am influenced by others discussion in #XDA. But when I came to meet some people in social chats, when I asked them for the, what are the requisites to be fulfilled while flashing #safe_rom without any brick.. Some says search rom on Google of your phone model i·e (gt-I9505) when I searched it there again appeared the case of #baseband version,there "google" when I got the other rom of my phone below it was written only for baseband "XXUHOJ2" and it didn't matched with mine.. In some post rom for jflte, jfltexx, sprint, .... And m confused all... And my question is.. Should all of those match to flash custom rom?? Isn't gt-I9505 all same??? Why should we consider #baseband for flashing rom or latest firmware?? Why?? Why?? Plz help me!!
-Thank you!
No baseband update
Hello and thank you for using Q/A,
you don't need to update or flash a baseband, if you want to install a custom ROM or stock ROM.
Kind regards
Trafalgar Square
And what about jfltexx,jflte, sprint.. Some post says rom for jfltexx, some says for this baseband only,, what to do in this situtation??? Is there any #compulshory to match baseband in order to flash custom rom??
Hi,
I've an I9500 who has Indonesian base, and I've flashed many ROMs designed for my device and I never had any problem. Baseband doesn't matter, however, an EFS backup should be made to be safe, so you can restore it later if you miss your IMEI after doing flash a certain ROM.
Because you've an I9505, any jfltexx ROMs should fit on your phone. You'll have no problems as long as you follow instructions provided by the developer.
I9505 doesn't stand itself. Some variants are released by certain operators in certain regions, like SPH-L720, SGH-I337, SGH-I337m, SCH-R970, etc. All variants who are on I9505 family are able to install jfltexx ROMs, but with some notes that might be available for certain devices.

You should only care about the baseband if you have a phone from Verizon or T-Mobile, as they generally have locked bootloaders.
Basebands are updated almost monthly. There is no way to have them matched.
You only need to care about your phone model.

Yes, mostly.
Hey XDA I have rooted and installed custom roms on various android devices in the past, and am now working on my Note 4.
I have it rooted and TWRP installed , but am now unsure if I need to flash a different modem or bootloader. I understand that the Canadian variant uses the T-Mobile Roms.
I am looking to install CMRemix http://forum.xda-developers.com/note-4-tmobile/development/rom-cmremix-rom-v2-5-12-23-14-t2981479 which is a T-Mobile Rom.
Will I simply download and flash it or do I need to do extra work first?
Thank you, and I apologize for posting this question. I was slowly going crazy after searching the forum for these things to no avail!
I figured it out. I checked by bootloader and it was up to date. I was having issues with Odin, but after reconnecting the USB cable 6 different times it finally picked up my phone in Downloading mode!
No worries. It seems that the N910W8 is basically the same hardware as the N910T3.
In the same way the Note 3 T-Mobile was the same as the Note 3 Canadian variant.
No need to worry about modems assuming yours is up to date.
Although, I must admit that while CM Roms tend to have interesting features, they lack support for some of the built-in hardware, and the battery life has been inferior in my own experience.
You should check out Temasek's CM versions.
Have fun
Hello,
I want to install a clean (non-carrier) ROM on my girlfriend's SGS5 (SM-G900W8). This is a canadian Fido phone. The reason I want to install the clean ROM is that they removed some parts of the ROM to scam people. For example, they removed a Data Toggle from the Notification Panel. Also, I want this SGS5 to receive updates as soon as they are out, not when FIdo decides to update it.
So I searched on SamMobile and found that there are just other carriers firmwares and 2 uknowns.
So my questions are:
1. What should I do in order to get a clean SGS5 rom on SM-G900W8?
2. What are those unknowns?
3. Is the phone going to work properly on Fido if I install other / non-carrier firmware?
Sorry if these are some stupid question. I am a Nexus user and never had these issues before...
The W8 version will definitely work with any of the T-Mobile roms and most of the other roms. If you're looking for stock roms, all the canadian carrier firmwares are cross flashable, meaning you can flash the firmwares from Bell, Rogers, Telus, Wind, etc.

Thanks for a quick reply.
Would you recommend any specific firmware? Without any issues and with the least amount (or absence) of bloatware?
I recommend the pure note 5 rom available in the developement section. It's very fast, stable and awesome battery life (I get 5 hours of screen time). I suggest waiting a few days since V6.5 is coming out soon though.

Oh, I thought that It's only OK to install ROMs for SM-G900W8 only. Can you please explain what kind of ROMs I can install on her SGS5 (SM-G900W8)?
I checked the N5 Port - looks awesome. I think I will install that one.
You can install most roms that are developed for the snapdragon variant. I installed the rom on my T-mobile S5 (G900T) and it works flawlessly.
