I recently switched from rogers to wind, and to do so, I needed to enable the two extra frequencies for penta band, which I have already done.
This said, I worry that if I flash a custom rom, it will wipe my modem and I won't be able to connect to wind's network anymore.
I do have a backup of the original via QPST, but would like to know before messing anything up.
Thanks!
Flashing a Rom does not touch the modem. It may mess up your apn settings though so if you have problems make sure they're set up correctly.

I have an SGH-T849. Trying to unlock it. Cant find any positive guides for custom roms or anything. Everything is only on the p1000 so I took my my chances and flashed p1000 firmware so I can fit in. But now I really need your help cuz network signal is a must and I lost it after the flash. I have my imei and everything is fine but the tmobile network wont register I am trying figure out how to fix this. I have tried copy and paste modem.bin to system/vendor and flashed the tmobile modem but no go.. Also I am in bad shape because I cant find stock firmware anywhere. All links are dead and samfirmware doesnt even have it listed. Any help would from anyone would be great considering this isnt my tablet
Not every Rom has modem.bin at /system/vendor
In fact most at /radio except for cm10 that was built about two weeks ago to last week.
Now all back to /radio.
And I am talking about ICS and JB Rom.
And correct apn is a must.
And JJB modem for T-Mobile

I have the correct APN. Also the modem.bin is in /radio as well and I also pasted it i system/vendor. No go. Question though whats the JJB radio and do u happen to know where i can find it?
Overcome gb stock safe has T-Mobile modem. Modem thread in development subforum sticky also has it.
But let me ask you this.
What do you see as baseband in the phone info.
Because even JPZ can connect to T-Mobile just no 3g. Edge only.
If has baseband and can't connect, can't help you.
But there is a person that has stock T-Mobile froyo and can share it.
You just have to search.

Well Itried flashing the the tmobile radio but it wont stick. Everything on the tab seems fine it just wont register the network. my baseband is JPZ.
Edit: I flashed Overcome stock GB and the tmobile radio... It went good my baseband is T-Mobile. However it still wont register the network. I am staring to think that the sim card is not activated.
Edit: Thanks much for your help. I am happy to say that my friends sim got deactivated. Up till 4 am thinking I screwed something up.
It sucks isn't it when another thing cause you to troubleshoot other things.
But, if you are on T-Mobile network and only going to use data and not voice call, your JPZ modem is going to only give you EDGE (2G) speed.
To get 3G you still need to use the T-Mobile modem I mentioned.

Every time I flash a rom I lose 3g. I've tried all the touch wiz roms like wanam and pyrana and everything works except 3g. It goes down to 1x. I still have data just not the 3g speed. Any ideas?

hi to help you out here goes,
its more than likely that when your flashing roms this changes your baseband (ie modem/radio)
to fix this you will need to remember what the original baseband was prior to flashing custom roms (ie when it was stock rom)
if you cant remember try phoning your providor who should be able to tell you.
then simply find the corresponding modem here on xda and wheather its a cwm file (.zip) or odin file (.tar.md5) flash that and 3g should be restored.
however which network are you on and do you have a sg4 (reason being is that its an lte phone built for faster web speed so if your seeing a (dc or 4g) all is well.
also you may have your settings incorrect in wireless and network/more/mobile networks
Yeah I'm on the sprint network and have the 9505. So it's capable of 4g lte but that's not available here yet. It is in Detroit and when I've been closer to there I've seen it switch to 4g but it's always on 3g down here in Ohio. I think it's kernel related as I was messing around with the stock rom and different mods like transparent status bar and different toggle icons and I figured I might as well flash wanams new version of the Adam kernel 1.4 and I lost my data connection. On the stock rom. I restoredit and it was back.

I am interested in enabling T-Mobile LTE on my N4. Does it work smoothly like any other LTE enabled phone? In my research, I've found that there are two different zip files to flash. Which one has worked best for people? It appears that enabling LTE is a simple flash of the zip file. Am I correct? Thanks.
This has been covered thousands of times. But before this thread gets deleted, let me help you out. LTE on tmobile or att works flawlessly.

Do I need to update the radios after every software update or can I just flash once and forget it?
Since this will get deleted anyways, I will ask the stupid question I have. Bone stock 4.4.2 soon to be rooted with TWRP. Can I flash with a stock ROM and still make a wifi hotspot? I see something about needing init.d support or something like that.

I flashed the file. However the instructions state to change the network mode. I don't even see that option in the settings. I'm currently on 4.3

My S4 is flashed to Boost Mobile. Whenever I install a custom ROM I get no 3G or 3G appears for no more than 2 seconds then its 1X. I nandroid backuped to stock and same problem so then I installed a Stock Deodexed NG2 Refitted ROM and right when this ROM boots Boost ID pops up it installs apps and puts it to my boost homescreen setting and my 3G and everything works fine. APN settings are the same when I switch ROMs so I have no idea what the problem is. I want to install a custom ROM like NegaLite but I am stuck at this point.
Have you tried using an app like apn backup and restore?
What are your apn settings on aosp? Are you on the latest modem firmware?

Right now I am on NG2 4.4.2 Stock deodexed NG2 Refitted ROM. This is the only ROM that my 3G works. My 3G worked on stocked rooted then I went to Negalite didn't work. So I nandroid to my stock rooted and 3G didn't work anymore so I tried this ROM i currently am on and it works.
My apn settings are all Sprint APNs and everything works fine and when I flash a ROM my APns are still the same but 3g is ****. I tried using APN backup and restore on this ROM it lets me disable ICS Check but when I install a different ROM that doesn't work so I can't use it. I even tried moving it to the system. I appreciate your reply

Are you sure it's true 3g on the refitted ROM. Sometimes it shows 3g but its really 1x. You can check under about phone status. 3g normally works for me as soon as I flash..no need to add apns. I only have to edit mmsc in APN settings to get MMS.
That's what usually happens to me. I installed Sac's ROM and everything works and I actually really like this ROM so I'm going to stay on here. I'm still trying to figure out how to remove this data stat notifiation or something on the top right and also how would I remove a NO SIM notification since I'm on Boost now I don't need a SIM
Hey, I'm using Boost Mobile and I've been trying to update to a custom ROM, but every time I do so it's just detected as a Sprint SIM card, which forces me to have 3G. If I reflash a stock ROM, support comes right back. I've already tried backing up my EFS and persist with the stock ROM, then restoring it after installing a custom ROM, and nothing changes. My IMEI is still intact, so why would a custom ROM not let me use Boost? Does it have something to do with APNs?
I remember using a Virgin Mobile phone with custom ROMs back in the day. If I remember correctly, you had flash a separate file after the ROM to get LTE support. I can't remember exactly what it fixed, but I do know it did the same thing you're experiencing if you didn't. Sorry I can't be more help.
