Flashing Firmware and Modem won't erase any data, correct? Do we know of any specific benefits of the new firmware and modem? I know they are usually better but anyone familiar? Thanks.

Shouldn't erase any data. If you flash the full tar file, it'll wipe you. That's for flashing to stock. Just updating bootloader and modem shouldn't erase anything (unless you do something dumb).

New firmware (if you mean bootloader) really doesn't do much but some ROMs (mostly stock ones) make sure your bootloader is a certain version. We're on T-Mobile so there isn't much to worry about since their bootloaders are unlocked to begin with so far.

New modems usually incorporate fixes and what not, but it's really YMMV. I usually go with the latest and if it seems worse I would just go back. I've never had to do this before though. I either don't notice much change at all, or at least know it's not going backwards. As far as my experiences with T-Mo HTC HD2 on AT&T, AT&T S3, and T-Mo S5. =)

BTW, I'm on AT&T LTE with G900T.

And thanks OP. =)

Any plans to make this a rooted flashable zip? I was thinking about it, but haven't had the time yet.

For all you stock rooted peeps that could not OTA:

Flashing the full tar will not wipe phone IF coming from the stock rom. All data and apps in tact. But it will remove root (superuser still present but does not work) and it will replace your custom recovery with the stock recovery. Simple to get back root with CF Auto root, and you can either Odin a custom recovery or use something like TWRP Manager (root) to get back recovery.

Does anybody know what the improvements are over the NH5 Modem? I flashed, and everything is running great. The radio seems more "responsive" to tower hops, and latches faster. Seems more stable. Will update in a few days.

From what I read, it's more focused on improvements to sms/mms over wifi. Possibly some VoLTE improvements as well.

Firmware at 2MB? Looks more like just bootloader.

What are the advantages to upgrading the bootloader if I'm rooted with a custom recovery? Are there any? I googled and couldn't find any answers.

Also, is there a bugfix/changelog for it?

Service reception is tied to the bootloader. Least was on the S4 , especially for data.

As far as change logs, Samsung never provides them.

But I can tell you it's probably a waste of bandwidth to download the entire firmware for this update and would just tar up the bootloaders and modems and supply those. There's zero changes to the kernel and most likely none to system

thank you for the sharing.

Just figured I'll chime in, i had to flash at least twice before it stuck.

make sure you totally power it off then use the volume down and home then power button to go into download mode, don't use the power menu restart from it.

I know that from past experience.

hope this help.

Hmm, didn't realize, maybe that's why it stuck. lol

thanks, i'll keep that in mind for future reference.

@keysoh2 - Thanks or the Modem/Firmware.

Hi Guys,
I'm on NG3 still and would like to do some updates. Can I go directly to NK2, or do I need to do updates in sequence? Also, using Odin with the two files in the thread doesn't take away root, does it; I just want to make sure?

Hopefully a lot. NH5 sucked for me. NG4 was better. Was getting 60 down on NG4 and only 50 down on NH5.

We'll see.
