[Q] What is a radio?

Hi, I have the Koodo T989D and I was thinking of flashing a custom ROM but I also read that you need a radio? Can someone else in detail what it is? What is the best radio? I'm using my unlocked T989D on WIND MOBILE in Canada. Thanks!

Most of the roms available here do not have the radio included in it, meaning that the version of the radio (System Setings -> About phone -> Baseband version) will not be overwritten.
If you flash a rom and find after that the phone disconnects from wifi or does not connect with your service provider, it is safe to keep a radio zip file handy.
You can find most of the available radios for your phone here:

There is no "good" radio. It depends on your location.
Fell free to test all of them and see which one performs better.

Alright so my phone is a Koodo T989D, would I be able to install lets say a T-Mobile T989? Also I see a lot of radio for Telus,T-Mobile etc.. which one would be the newest and better one compared to call those like the multiple ones.

i would say to use a TELUS radio because TELUS is Canadian it should get you a better reception

Ok and it would work with 4.0.4 or with any custom rom such as the 4.1.2 CM10?

radio can be flash with any rom

I have the same phone and am using it for Mobilicity. I'm using Liquid Smooth RC7 right now with UVLH1 radio. This combination works well for me. I know RC 9 is released but I haven't had a chance to try it yet. RC7 is working perfect for me so I am reluctant to flash the new version.
But just as others have said, try different radios to see which one works best for you. Everyone is different depending on where they live. Just remember to Nandroid it first before trying anything.

Ok, how do I flash it? My phone is rooted. So if I flash the TELUS one and follow the process, my phone can't be bricked right if only I did a wrong step.

Before you flash anything, remember to back up your stock rom first in case you ever need to change it back for warranty purposes or in case your messed up somewhere along the way.
Once its backed up,then you start to flash the rom of your choice. Just follow the instructions laid out by the dev. Your radio wont be affected when you flash a rom. You can flash the radios separately afterwards. I use Cwm without any issues but others use TWRP. Use what you are comfortable with. You shouldnt soft brick your phone as long as you flash the ones deigned for our phones.

Ok, so how do I backup this rom? Also if I want to still use this stock koodo rom, can you show me the step by step to install the TELUS radio? Right now I have the koodo radio but if I install the TELUS radio, it will change the radio by default to TELUS right?

1.Reboot the phone into recovery and backup current ROM.
2.Pick a radio from http://forum.xda-developers.com/showthread.php?t=1895400 and download zip file.
3. Reboot into recovery and flash zip file.\
Check to see if reception and data speeds improve. If not, try another radio until you find one that works for you.

Ok, first I don't know how to backup the current rom? I have this recovery file and the stock koodo rom. Second I saw people on youtube wipe the cache and other things. Do I need to do that as well? If so what else do I have to wipe?

So I just installed the TELUS radio and it didn't work so I wanted to revert back but whenever I shut down, the capacative touch buttons on it won't turn off which causing me to take out the battery to turn back on the phone. Why is this happening?

What do you mean it didn't work? Are you not getting any reception or data? Did you check your APN settings? You can always restore the backup if you remembered to do so before you flashed the radio. Or you can flash the Koodo radio listed in the radio link from my previous post.
Not sure why the buttons stay lit. I never had that before. Maybe a different radio doesn't work with stock rom. Try to flash a custom one. As stated before, try Liquidsmooth or CM10 Stable.

[Q] - N7100XXUFNG4(FND2) to N7100XXUEMK9(MJ9)

Good day to all!!!
I've gone into bootloop, and having a hard time finding a link to my previous rom which is N7100XXUEMK9-COA(MJ9). So I decided to download at Sammobile a N7100XXUFNG4(FND2) -Philippines coz I'm from Philippines. And I flashed it thru odin. Installed PhilzTouch, rooted and done. After using it for a few days, while reading some threads to other forums. I finally found a link to my previous rom. I've successfuly downloaded it.
I'm just wondering if I can directly flash this N7100XXUEMK9(MJ9) back to my phone which is N7100XXUFNG4(FND2) now using odin again? Can I flash this without losing my IMEI, Modem, Wifi or my EFS being corrupted?
By the way 4.4 is fine. But on my own observation, it drains my battery faster than 4.3. So if there's a chance getting back to 4.3, maybe I'll grab the chance. If it's going to be complicated, maybe I won't do it anymore.
Sorry for a the long story. Hope somebody can help me. Thanks all.

Anyone? Please. Thanks.

I am unsure about this, if you have upgraded bootloader, you are stuck with latest bootloader, however you can downgrade rom, unless I am mistaken.

Thanks. But actually this has been answered to the other thread of Dr.Ketan. Here's his post http://forum.xda-developers.com/showpost.php?p=55076259&postcount=571
dr.ketan said:
You can't downgrade with Odin if your existing bootloader is kitkat. Though you can use mobile din to downgrade to 4.3. And regarding IMEI, No one can say whether you will lose it or not because even you doing everything correct there are still minimal chances to lose it (any bad flashing can cause it) but make EFS backup and copy it to multiple places. I stroingly recommend to make backup efs in .img format (search play store for "Dr.Ketan Hindocha" and you will find IMEI Tool N7100/N900 which makes backup on said format)

DN 3 v5 doesn't recognize SIM card

ATT Note 2 4.4.2
Downloaded Electron Team DN 3 v5, nice looking rom, however, I have no phone service. When I go into settings to networks, it is asking for a SIM card.

Check to see if you need to flash a modem. What baseband does your phone show?

baseband version "unknown"
also getting a ton of "unfortunately, calendar storage has stopped...etc

Sounds like you need to do correct wipe procedures and reflash the rom. You also need to flash a modem.

Trouble is, I don't know which modem to flash. I just tried flashing one, but didn't work.
For some reason this is the only rom when i flash, that kills the modem.

[Q] CM 11 M12 - No Service/Data

Hello,
I OTA updated from CM 10.2 stable to CM 11 M12 snapshot and I installed the gapps separately. Almost everything seems fine except for "No Service" issue. Data connection is not working, but am able to make and receive calls. There is no APN settings and adding one does not gets saved.
I searched xda and few threads state that it is due to old modem. However, this thread in xda says that the bootloader and the modem version has to be match, otherwise installing a modem with mismatching bootloader may hard brick the phone.
According to "Phone info *Samsung*" app my
Bootloader version is : I747UCDMG2
Baseband version is: I747UCDMG2
1. Do I just get the latest Modem ONLY from this thread or do I need to get BOTH bootloader and modem from dstruct2k thread.
2. If I can't solve the issue, can I just flash stable CM 10.2 back with corresponding gapps? Will it cause any such issue, because somewhere in the above thread it was mentioned that dowgrading modem might hard brick the phone too.
Thanks in advance. Any help is really appreciated.

Looks like your bootloader and modem are too old to fully supported your updated ROM.
You will need to update both; however, once updated, you can never downgrade either to be safe.

Thanks. Is there a order in which both has to be flashed like bootloader first and then modem next? Do I flash both at the same time or flash one first, reboot and then flash the other?
Also, if I don't proceed to flash the new bootloader and modem, can I safely flash CM 10.1 now without bricking the phone?
Thanks again for your reply and help.

has bootloader/modem combo zip. i think mjb and ne4. just flash and it updates both at same time. be sure to read OP first though.
"all i can really do , is stay out of my own way and let the will of heaven be done"

Both should be flashed in tandem.
Yes, you can go back to cm10.2 as cm roms don't flash a bootloader or modem.

Thank you very much to both of you. I followed the thread you mentioned and installed the MJB bootloader/modem combo and I got the data connectivity back. I did not install NE4 though as I dont really need it now I guess. Thanks again.

good to hear you got it fixed. :thumbup:

Hm. If you're rooted, I assume you know how to use ODIN, correct? Also, since you've got a custom kernel, I also assume KNOX is tripped, correct. Making both of those assumptions, I recommend you download the DOI1 firmware from Sammobile or XDA and flash it using ODIN. I may be wrong, but it sounds like you have a modem issue, and re-flashing stock should help.
