[Q] Should I install NC5 modem? (MDK base)

[mageus]

VZW S4 16GB
MDK bootloader
MK2 modem currently
Vanir 4.4.4
TWRP recovery

I'm running Vanir (previously 4.3, now 4.4) with the MK2 modem. Clean flashes with wipes, both ROM and modem. Bluetooth has always been a little finicky, more so with the 4.4 upgrade. Never had a problem with my cars with previous phones (e.g S3). Also, data/LTE occasionally stops working requiring a reboot (every few days). A search of the Vanir thread doesn't bring up any persistent issues with the ROM itself.

Would there be any issue installing the NC5 modem?

I was going to try reflashing the MK2 modem, and then Vanir itself. However, since the issues are all modem related, I thought I'd try NC5 first. I'm also wondering if 4.4.4 has any issues with older modems.

You don't want the MK2 modem. Either flash gigiles fix as decaturbob said or the nc2 or nc5 stand alone modems. Use the modem for the rom you are running.

The issues with your data are most likely not the modem. A few of us had this same problem on various aosp Roms and switching modems did nothing at all... It was to do with the apns in the accrual ROM. Bluetooth as well. Some had issues with BT on Vanir too I recall.

One of my friends on here can't even run certain Roms I can due to the BT deal and we have our S4s set up the same exact way...

In the end I suppose it can't hurt trying a new modem. The NC5 one should cover you but pretty much just keep trying different Roms as well and see if those problems continue...

Thanx for the feedback.

... It was to do with the apns in the accrual ROM...

I presume what you mean is that the AOSP ROMs were built off a specific ROM as base, rather than compiled from scratch, and that ROM did not have complete APNs for VZW? Was there a fix to add the correct APNs?

Is the gogolie fix for wi-fi only? I don't have any problems with wifi.

I found gigilie's SafeUp/Down post, but couldn't find the post about the wifi fix. I found a repository "gogolie mogolie" on androidfilehost. Is that trustworthy?

I think I'll try to upgrade to NC5 first, then gigilie's fix.

@mageus if you go to this thread there are the zips you need. http://forum.xda-developers.com/showthread.php?t=2487298
you have no need for the wifi fixes or nc2/nc5 modules
the only benefit from mj7-nc5 is that is enables aws band 4.
other than that the modem you choose should be the one that give you the best service/reception.
you will just have to try them out.
