Hey all!
So the NC5 update comes with a new modem (modems are labled as Baseband in settings I believe, correct me if im wrong)
So with the new NC5 update, with the focus being the new modem, it has me wondering about the effect that flashing new AOSP roms have on the modem.
AOSP roms for the note 3 have been merged to be compatible with all variants of the Note 3. So im wondering when one of these AOSP roms are flashed to touchwiz software... what remains as touchwiz and what is AOSPifed (for lack of a better word)
Im asking specifically because of the modem, if NC5 comes with a new modem, and AOSP is compatible with all variants, wouldn't the modem be changed? And a simple twrp backup of Boot, system, data wouldn't include the original modem... would it?
so far this is my understanding of what is and what is not effected by flashing an aosp rom on a toucwiz device-
Bootloader- not effected: note3 touchwiz kitkat booloater is compatible with all kitkat note3 roms, aosp or touchwiz
kernel- yes, changed to an aosp kernel, but a simple twrp restore of boot and/or system will restore the correct kernel you were previously on
rom- Yes you will not longer be on toucwiz based rom, but again easily restored correctly with twrp
and then theres modem/baseband- will the baseband/modem remain the same? how would that work if the roms are universally merged?
and I believe the standard twrp boot, system, data will not restore the baseband, as there is a separate modem option.
and I would be weary of restoring the modem on the note3 because after doing some reading in the note3 forums changing/replacing, or even jumping to older modems (NC5-NAB )without the engineering bootloader can be catastrophic (for lack of a better word lol)
So hopefully this post makes sense as I have tried very hard to explain the dilemma, any input would be greatly appreciated.
Thanks!
The radio stays the same .... There is a ril between the rom and the radio .... radio interface layer any radio will work with the aosp roms ... Hardware may get a little better signal with one over the other but they will all work. .. cyanogen or aosb etc paranoid they have ril just like the Samsung rom has ... The modem is separate software. .. like a bootloader is also

Thanks for the reply!
I think I understand the basis of what you are saying..so basically the modem/baseband will not be affected at all when flashing any aosp roms...right? and when you say radio you do mean modem, the modem stays the same?
Sorry I am clearly very limited in this area so I dont really understand what you mean by "a ril " or a radio interface layer. I sense they may be very complex topics and a lot to describe, so please dont feel you have to waste your time going too much in detail. Though of course if you have the time I would love to learn
But basically I hear I should be clear to AOSP flash away, without any issues with the modem. which is great!
thanks again! :good:

Hey anyone that's got some noob time, I was curious what exactly is a kernel, why are there different kernels, when to know if you need to use a different kernel and lastly instructions on how to flash a kernel. I am pretty experienced in dealing with my phone and I'm capable of bringing my phone back from ANY software brick with ODIN and I have been flashing ROMS for about 5 months. I recently was reading up on the Epic 4g forums because I was going to root my epic when I buy it and I noticed much more about kernels in the epic 4g forums. Any knowledge would be appreciated! Thanks!
Roms, Basebands and Kernels, a basic overview
The baseband is only the 'radio' part of the phone that makes the calls, the 3G and Wifi connections, GPS connections, etc. As you thought, it is totally separate from a ROM. Updating a ROM will not update a baseband and going back to an older ROM will not 'downgrade' the baseband either. Upgrades to a baseband my improve signal strength, call quality, maybe have software tweaks to improve battery life while on 3G/Wifi, etc - things like that.
Kernels are the core software code that allows CPU to over-clocking and controls voltage controls. Think of it like Bios settings on your computer (PC, that is)..that's really all they do. Now, a kernel can be completely separate from a ROM, but a new ROM contains a kernel in it so it will run. So, a kernel can be both separately applied from a ROM, but is also part of a ROM.
The ROM is basically everything else but the apps and the two things above. It's actually the OS, as well as any stock apps that come with it - and any new improvements, features, etc. The increasing build numbers reflect bug fixes, known issue solutions, feature improvements, etc...thing of them like windows service packs and/or any software update.
Some of the other phones modifying the kernel may be done more because the phone design and limitations
Hope that helps
Very helpful, I was sure to click thanks. I'm curious how to change the kernel on my phone and when should i consider changing it. Do I use ODIN to change the kernel? Also can any kernel work with any ROM? If not, how do I know which ROMs a specific kernel is compatible with?

Most kernels can be flashed just like a ROM, very few require ODIN and if it does the dev will specifically say so. Also not every kernel works with every ROM. However they are usually made to work with any ROM base don a version number. For example if a kernel is made for 2.2 than all ROMs that are made from 2.2 will work with it. The version number a kernel is meant to be used with is always in the OP of its thread.
And one last thing, if it is a kernel that has to be flashed via ODIN could someone give a step by step? I've got return to stock via ODIN memorized and I've done it plenty of times but not sure about the procedure for kernels.
Put the kernel in the PDA do not repartition, On a side note, when you are flashing things especially adding new kernels etc, It is better to go to recovery manually and do it from there. Sometimes the custom stuff or CWM have conflicts and it doesn't flash and you have to go odin back......... that's been my experience
so just use adb to get to stock recovery and then choose install packages? forgive me for my extreme detail

Have you been using 2.2.1 ROMs?? I always have to ODIN from 2.2.1 ROMs cause I can't wipe data from CWM on them. So when it gets to that part of flashing the ROM it freezes

I flashed a modem from that thread but GetRIL still tells me my RIL and baseband dont match
You cannot and must not flash a modem + ril on aosp roms. You cannot and must not use getril on aosp and regardless, worrying about rils us pointless and makes almost no difference.
On samsung roms, only bother looking into rils if you're having serious issues. Otherwise ignore.
Aosp roms use openril. Do not do anything about rils on aosp roms

the thing is, i get a lot of wakeclocks for reception related stuff. How can I solve them?
If better battery stats shows clearly that, change just the modem, without ril (in aosp Rom if you change the ril you won't have any reception/call at all) as long as you don't have the proper result.
Be sure it's not an app providing this flaws.

greenified everything that could have done that. I dont have many apps either. still, i don't know what modem I need and where I can download it since all I've seen is for 4.1.2.
By the way Im on 4.2.2
It doesn't matter. Try all modems (without ril). Modems are not tied to rom versions

I was running Omni rom on my Galaxy s3.
I changed it to omega rom v46.1.
After I did that, I noticed my simcard wont read on my phone but would work perfectly on other phones....no simcard will read on my phone and I will just get an error message saying "not registered on network".
I downloaded GetRil and found out that my baseband and Ril do not match and I knew that this could be the only cause of the problem.
My Ril is I9300XXLE8
My baseband is I9300XXUFME7
Can someone please help me find the Ril that would match my baseband version.
THANK YOU!
I'm on Verizon. I tried installing both the GPE rom and cyanogenmod 10.2. When I do, I immediately encounter cellular issues. I'll lose cellular data often and require a recycle of mobile data. It was definitely worse on cm but I'm wondering if my issues stem more at the kernel level? Maybe the VZ stock kennel isn't compatible with these Roms? If so, is there a kernel you recommend?

Looks like I already have the latest radio, so that's good. My question in regards to the kernel is, does it affect radio? So, before I switch kernels, just wanted to check if I'm going down the right path. Thanks a lot

Ok simple nope. a least something is wrong with the kernel, kernel have more to do with battery performance, display, smoothness scrolling and wifi to my understanding.
radios signal = to have the correct driver for the modem Ril (Radio Interface Layer)
Hi all,
Before I get yelled at, the search feature isnt working currently on XDA, so my apologies for something that has probably been asked multiple times.
I'm looking for 'that' ROM, you know, a daily driver, and I haven't come across one that I like just yet. Some of this has to do with my signal strength (I know TW will always have a better signal than AOSP). I'm still on the MDK baseband version. My first question is will an upgrade to ME7 make a noticeable difference? If yes, where and how do I go about flashing it? On my S3 I was able to just flash a zip with the new radios, but I understand now ODIN is necessary.
Any help would be greatly appreciated, thanks guys!

What rom are you on now? The reason I'm asking is because if your on stock you might as well flash something like Darkslide which is stock minus some bloat and includes the ME7 baseband. ME7 is in my opinion better but nothing drastic.

Currently I'm on an AOKP build, but I'm planning on flashing Beanstown's ROM. It says right in his description that he recommends the ME7 radio with his ROM. Not sure if flashing it would just give me the baseband.

He updated that in release 6 so just flashing the rom will update your baseband. Picture in picture and smart scroll will not work on the stock kernel....if you use them you will need to flash a kernel that supports it.
Hi guys,
I know with phones I've had in the past, we could flash roms from other carriers as long as we flashed a Kernel for the carrier you're currently on. Is this the case with our Sprint Note 3? There aren't a lot of roms available for our variant, so I was hoping to find more roms to experiment with, but don't want to mess anything up. Thanks in advance for your help.
First, what OS version do you have on your note 3. If you have updated to 4.4.2 NC5 you CANNOT downgrade to a older version of KK like NAB. Assuming you have, then you can only flash KK 4.4.2 based roms . I don't think you can flash roms from other carriers as the Basebands won't match.
EDIT here is some more info; ( Thanks topherk )
If you "dirty flash," there's no problem with that, just know that if you ever encounter an error, we will be unable to help you in any way.
You're right, cross-flashing might leave remnants (features) of the previous ROM, but there's no guarantee that they'll be utilized correctly or linked correctly to the system files. As far as I know, the "worst" thing that could happen by dirty flashing is an unrelenting boot-loop. In those cases, you should just do a full system wipe and re-install the ROM.
I recommend, as Micmars does, a full system wipe prior to installing any ROM, but to each their own.
Typically, ROMs do not install different modems. As far as the MJ4 vs. NAB vs. NC5, here's a little primer on the various versions:
MJ4
This was the last Jellybean TW released for the Sprint Note 3. If you are on MJ4, you'll have to update your bootloader to NAB (or NC5) in order to update to KitKat ROMs (and you can't go back). The
NAB
This is the first KitKat TW ROM for the Sprint Note 3. Once on NAB, you can't go back down to Jellybean (yet... some people are working on it). You need to be on the NAB or NC5 bootloader in order to flash these ROMs.
NC5
This is the second KitKat TW release for the Sprint Note 3. It introduced some updates to the system and it includes WiFi calling (I've never used it, but others say it's really nice). You can flash back and forth between NAB and NC5 ROMs as much as you want, without changing anything. You need to be on the NAB or NC5 bootloader in order to flash these ROMs.
As far as updating to NC5 ROMs, just look at the changelogs between the NAB and NC5 versions of the ROM. If the added/changed features look appealing to you (or it looks more stable), then by all means update.
As far as modems go, I always stick to the newest Modem, which always tend to work best for me (I'm in a large metropolitan area). Sometimes people will report that the older modems (MJ4 or NAB) work better in their area. The Modems are completely separate from the ROMs, so flashing an older (or newer) modem should not have any affect on the stability of the ROM. It's really up to you if you want to update it.
As far as bootloaders go, if you are already on KitKat ROMs, I'd recommend updating to the NC5 Engineering Bootloader, but as long as you're on NAB, you should be fine. Just make sure to read the OP of any ROM you flash, they typically will tell you what version of the bootloader you need to be on.

I'm fully aware of how to flash roms, and the merits of not "dirty flashing". What I'm curious about is whether or not we can find, for example, an AT&T Note 3 Rom, flash it on our phone, then immediately after flash the Beastmode kernel for our Sprint variant, and be able to actually boot into the rom and not lose the important things like wifi connectivity or 4g connectivity. I remember with other phones I've had in the past we were able to do that, without any major issues.

I took the plunge and tried to install a T-Mobile rom, and it booted up fine, I could make phone and receive phone calls, could receive texts, but I couldn't send any. Not sure really what I would've needed to do to get texts working properly though so I went back to my nandroid. Tried following a guide to get the rom working on our carrier, and the rom wouldn't flash. Thanks for the help though, I appreciate it. Looks like I'll just stick with the Sprint Roms.
