So I'm rooted sitting on 5.1.1 and I have a backup. One of the main reasons for rooting was to enhance performance and cut the fat without loosing my S-Pen. That being said I've noticed my data speed steadily dropping over the months and I'm attributing that to the old radio firmware. I understand how to flash the firmware from odin but it is safe to flash the 6.0.1 PF3 radio over my 5.1.1 PA1. Could i also flash a Kernel that may help with performance or battery life. Is flashing portions of a full firmware safe in general. We all know the bad things that can happen when just doing these things without asking, and i'm not finding clear answers. Any help is greatly appreciated.
same boat almost
dam man I was just trying to hunt down some of the same answers hopefully someone can chime in here ... but I'm kinda looking at trying to go backwards and trying to find some clear answers about the fact that the note 4 does have dual radios and newer phones don't ... my question is looking at does the newer firmware turn off one of the modems to preserve battery ... the BPA1 moden really seems ****ty but I'm running stock rooted 5.1.1 i may be trying to reflash the modem itself first

If someone could just clear few things for me i would gladly appreciate it and maybe users who have the same questions could use this thread maybe in the future to clear any problems or issues as well.
I was on firmware 1.26 before i rooted and flashed the latest ARHD rom. From what i gathered though my HBOOT is still the same. Not sure about radio but Hboot is still on 043. What are the benefits of changing to a newer HBOOT firstly please?
Also regarding flashing boot.img. i know that is the kernel. but my question is why not just make a kernel out of it? or is the way creating kernels different from say samsung phones? Any benefits in flashing that each time we update roms?
Kinda having bit battery drain on latest firmware as well. is that normal now on 1.28 firmware? thought that would be better with the latest batch instead of being on old firmware.
Why do we have to go through fastboot to do things and not just through cwm recovery and how comes no cwm manager app?
Instead of updating through OTA can we not just update through custom roms each time a new firmware gets released? And if not why go through the whole process of going back to stock just to do that then and then reflashing the custom rom again?
Those are few things that i would like clearing up please if possible. I am loving my phone and with research and by reading it is going through the whole process of learning again. But there are few things like i said i would need clearing up and if someone would be kind enough to answer as much as they can would be appreciated. Many thanks much appreciated in advance
anyone?

My sister's Note 2/N7100 got notably worse after getting official android 4.3 update N7100XXUEMK9: battery life is almost halved, and wifi connection is very unstable, with lots of disconnections and week signal strength. None of this happened while the phone was on official 4.1.2. I think these problems might be related to the radio module, and flashing an older, known to work, version might do the trick. But flashing the radio requires rooting, flashing custom recoveries, and such, and i've read many scary things about Knox. Is it possible to downgrade only the radio module without touching anything else and without tripping the Knox flag?

Pretty sure Wifi is completely separate from 3G radio.
I suggest you perform a factory reset from within the phone settings. That really helps after major updates. Note you will lose your data, backup to PC or SD card your photos music etc. Plus of course your apps start from scratch too.
MKp is old news now. Consider rooting and putting a newer factory image e.g. NA1. If you decide to do so, you have much reading ahead of you!
Good luck.

I think this screenshot should have all of the relevant information. I would tried this sooner, but it was end of college, I got my first full time job, etc etc.
My main issue with this phone is that it does random "soft" resets where everything just comes down and it reboots to the lock screen. This is especially fun when I'm driving and using this as a GPS :laugh:. I'm pretty sure the kernel is involved somehow, but I honestly don't know.
I want to know:
1. What do you guys think would be the most efficient way for me to update both the ROM and Kernel?
2. Is there any way to do this without having to re-root?
3. Would I be better off just choosing a non-stock ROM in order to get to the latest version of the android OS more easily?
That's about it, pretty simple. Just some directions would be nice as I'm quite out of the loop. Thanks.
If you don't want to do the research or take the time to go through the trouble of reading through these forums, then the most efficient way will be to remain stock unrooted and update via the approved methods from your carrier and/or Samsung (OTA and/or Kies usually). All software versions from ICS on up (non international S3s are now officially on KitKat) have been covered extensively by now so I doubt anyone is going to entertain your direct request for information. There are many things you need to be aware of, such as but not limited to how the new bootloaders and KNOX, as well as how custom roms and kernels, are working together in the big picture of things.
NOTE: Regardless of which route you take, no one in this forum, including myself, is responsible should anything happen to your phone. Anything you do to your phone is at your own risk, including official updates from your carrier and Samsung.

You can get all the info you need here: http://forum.xda-developers.com/showthread.php?t=1725839
As for having to re-root, you won't if you flash a custom ROM. Getting the OTA (or Kies) update will require a re-root which can be easily done with Towelroot.
As for the "most efficient", just follow the ROM's OP instructions to a T - it''s usually straight forward and easy to follow.

Thank you for the reply
Okay so basically the most (time) efficient way for me to update is to get some custom ROM. That's fine, all I need to work on my phone is a few programs nowadays. Namely Google maps and the phone (well and the browser). Is Kernel updating the same? What's one of the good kernels and roms these days for the purposes battery life?
The main reason I'm making this topic is I'm fine with just going out and following directions, but I'm updating from such an old version that I'm wondering if there are any "gotchas". Like I update it to this with my old kernel and the thing is suddenly bricked. That's really what I'm worried about.

Kernel will be overwritten in the flashing process. All you gotta do is make sure you recovery is up to date if you go the custom ROM way.
We don't make suggestions as for what ROM/kernel to use to avoid flaming and it also comes down to user preference. Although, I do suggest starting to look at some custom ROMs (most of them come with their own kernel but can also flash another one). It will most likely come down to AOSP vs TW (stock) base.
The closest to a suggestion I can make is to look at the top threads in the Dev section, those are the most "popular" ROMs/kernels.
Alright, looking around at the various threads in the development section I see that most of them look pretty simple to install. Just download the zip, reboot into clockwork and install after doing some resets.
I notice that some of these require a new bootloader/modem, though... I haven't seen those terms when I last did this. What are the general installation instructions for those; the same as custom roms? Can they brick your device (assuming that I even pick the one for my device)? I'll probably just install something that doesn't need me to update the bootloader/modem to make things simple.
For the most part, if you've updated to 4.3 you will be able to flash any available roms. The catch is once on 4.3, you cannot downgrade your firmware.
Firmware is updated either by ota or flashing with Odin.
I went ahead and got the Slimkat because the instructions for it were pretty easy. There are some unpleasant changes about it that I would like some assistance on, but I suppose that would go in the dev thread to ask about those. Thanks for the info, it helped give me some confidence about just trying it out. Like I said a little iffy about some of the things but overall I like. At least it hasn't randomly crashed on me yet, and getting all of my apps back was as easy as having TitaniumBackup extract them from my Nandroid backup.
I have had several issues with the 4.4.2 OTA update on my I747 . The most annoying is the battery drain and "hot phone syndrome" which apparently is a bug related related to the camera daemon. Details can be found here http://tinyurl.com/KK-Batt
My goal is to throw 4.4.2 in the bit bucket and go back to stock 4.3 (when life was perfect), however I am leery of the older ROM's running on the newer NE4 bootloader and modem. I have done much reading on XDA for the past week (scortched eyeballs) but haven't found a 4.3 ROM that gives me any confidence ( they all state specifically to flash the MJB or MJ2 level firmware)
Has anyone sucessfully accomplished running 4.3 on the new NE4 bootloader / modem ?
I read a post from @DocHoliday77 that said this "should" be possible .....but I cannot afford a brick. The phone is my ISP, as I have no cable or DSL available , just a mediocre LTE signal from ATT (for which I am grateful)
I am considering this ROM http://forum.xda-developers.com/showthread.php?t=2504903
Thanks for any info or suggestions that you may have
You can flash any ROM you like as long as the ROM does not attempt to flash a new bootloader or modem.
The reason many ROMs require the 4.3 bootloader and modem is the fact that the ROM requires these two things to function properly.

Thanks for the response audit13 , that all makes perfect sense ..... I was hoping maybe someone out there had suffered the same plight and tried this solution.
I read that the problem won't be corrected until android "L" (they attempted to fix it in 4.4.3 but failed). To me this is like Ebola for Android so I don't understand the lack of urgency by Google to correct it ??? Also, one would think a developer would have suffered this plague and been motivated to fix it.
This is not necessarily a Google problem. Samsung ROMs use Samsung kernels, not stock Google kernels.
Samsung is on 4.4.2 while custom ROMs are at 4.4.4.

Yes but the problem exists in the Nexus line as well, looks like Sam inherited it in the source code. I have thought about trying a different kernel , but IDK if the problem is with the kernel or the daemon or a combination of both.
@audit13 since I am mostly a NOOB here maybe you can help me. I am about to try a custom ROM but am leery that they may mess with my bootloader and modem (NE4) is that possible or typical when you flash a ROM? or do they always state it if they do?
I was running the latest version of Liquid Smooth 4.4.4 and never experienced excessive battery drain or a hot phone on my Nexus 4. After a few days, I installed a custom kernel and my battery life improved but not by very much. Maybe I have been lucky with my Nexus 4. I tried Android L on my Nexus 4 for a while but didn't like the interface. Again, battery drain did not appear excessive on L.
I Don't have KK on my s3 as it is running 4.3 bootloader and modem with a custom ROM.
It is possible that a custom ROM will attempt to flash a bootloader or modem but I have never seen this happen other than a couple of ROMs for a Nexus 4. To ensure that a new bootloader/modem is not going to be flashed to your phone, make sure you look at the first few posts for instructions and warnings.

Thanks for the feedback @audit13 much appreciated ...... I feel better now. I think I will try upgrading first since there has been no specific feedback on downgrading and my gut tells me it may not be the best idea SlimKat 4.4.4 looks interesting.
Hopefully you will not see a post from me in the future that starts with HELP !!!
I also have never seen a rom that flashes the bootloader or modem. Doing so would be a HUGE mistake!

@DocHoliday77 ....... Thanks Doc
venturing into these waters again? I have an old T-Mobile Galaxy S3 that I'm basically trying to turn into a gaming phone, just to play games on for my niece. However this thing hasn't been updated in forever and some of these newer games won't run on the firmware I have installed currently. I'm sitting on Android 4.1.1, running an old version CMW recovery. I just want to update to perhaps KitKat so that the games will run. As it stands now, trying to install leaves certain apps hanging on installation or simply incompatible with my version of android. I've been reading various threads in this forums and I'm seeing things about needing certain recoveries to upgrade, so forth and so on so I wanted a little expertise knowledge before I tried anything.
Would I be ok just picking a KK Rom, doing the wipe routine, flash and be good to go? Or have things changed and more steps are necessary, or newer versions of recoveries and what not are needed? Really don't want to brick this S3 so any help is greatly appreciated. Thanks in advance.
I've found you need to update the recovery or you have install errors when trying to put a newer ROM on the phone. It might also be worth updating the modem even if you never use data or the phone features. So, yeah you kinda need to update everything or else you run into issues since a newer rom relies on features that might not exist in older firmware.
Thank you for the reply, my recovery was severally outdated and I wonder what took me so long to upgrade to TWRP. It's great. I was able to flash with no issues and glad I did.
