hey all, im not quite as active as i used to be, and ive been with W03 slim rom for about a year now with no change. but its been acting up lately so ive decided to go to stock. thing is, when i upgraded to 4.4 i remember something about not being to downgrade back to 4.3, as updating the bootloader was irreversible. can't find that info anywhere now, so my question to you is:
can I upgrade to the NF9 baseband from NB4 baseband with W03 slim v25? its 4.4.4. Is it as simple as using this guide? http://forum.xda-developers.com/showthread.php?t=2765014 i would download the effortless prep file and odin to Full Stock NF9. That will put me at regular old stock right? i wont have to worry about bootloops or bricks? i use my phone for work and cant lose it, but also cant continue on with the random reboots and data drops. and from there i could root and install, say, hyperdrive RLS5? thanks.

My note 2 has always been stable on 4.1.1 stock and I debloated it myself. So when ever an update came out rather than risking my stable phone I would just flash the new baseband from it and keep 4.1.1, until tesh stopped updating his thread. Recently my screen cracked so I used my insurance for the first time. The new phone came with 4.3 and the knox bootloader plus the CMK7 baseband. I did a cwm backup on my cracked screen phone. Used odin to flash cwm onto the new phone, which did cause knox to show I did but who really cares since the phone is so far out of warranty anyway. Then loaded my cwm backup onto the new phone. What I ended up with is my nice stable phone with everything working plus the new baseband CMK7 stayed but the bootloader is still the new knox one. Everything is working just fine, so whats the big thing with everyone saying you cant go back from 4.3? I went from 4.3 to 4.1.1 just fine via cwm.
Cool story bro

If you use PC Odin to go backwards there are uncomfortable results.

How many of your posts are worthless? All of them? You sir are whats wrong with xda. The fact that every one thinks you cant go backwards from 4.3 just got proven wrong as long as you do it with cwm and not odin apparently.
There are multiple threads regarding your cool story.
The issue people are having is not being able to downgrade to 4.1.x OS. Its the bootloader that people were discussing and when coming from a 4.3 bootloader is impossible to downgrade to the 4.1.x bootloader/s.
Maybe doing a search in the future will get you some answers about the whole 4.3 bootloader and downgrading that you're taking about.
Good luck to you..
Ok but like I said I have the 4.3 bootloader and a 4.1 rom with no issues using cwm. So there is no issue with having a 4.1.1 rom and the 4.3 bootloader. If you have nothing constructive to add then dont post anything.
I mostly Lurk on XDA, But you sir are a different kind of stupid.
Clearly you haven't played with 4.1 long enough to see what the issues are, Its been well known that you can return to a older rom.
but knox has issues by doing so.

Lol long enough? How about since release day when I bought it? My phone is stable as can be with no force closes completely self deblaoted, working wifi tether, bunch of xposed modules and everything is pefect. For the most part the OS that a phone releases with is typically the most stable, there are obviously exceptions but I have been doing this since the G1 days and as soon as you start getting flash happy is when you have issues. Only thing I update is the baseband/modem. Also dont name call over the Internet its childish but then again most people on here are typically teenagers. Could you elaborate on the issues knox should be causing me but isn't?
This topic has been mentioned many times, there's no room for the useless bickering going on in here.

Hey guys long time lurker here who needs some help,
First off, this is what I have on my phone:
Baseband: I747UCUEMJB
ROM: QuantumRom/QuantumKernel (Latest)
Philz Touch Recovery (slightly old)
Main Question: I want to completely wipe my phone (pretty much nuke it) and reset it all the way to where I still have a rooted phone and can put on a custom ROM. How do I go about doing this?
I want to do this because I may sell my phone later on down the road (approx. 2-3 months) and I want to clean out all the stuff I have, but I still want a phone that is rooted and able to sustain custom ROMs. I know this may seem like a noob question, but I want to make sure I do the process right and not lose my phone.
I'm not 100% sure but wiping data, cache, and Dalvik would pretty much wipe everything on your phone.
Alternatively, you could use Odin to flash a ROM.
The thing is, I wanna go back to pretty much stock with root. Like wipe the whole phone clean.
To go back to stock from MJB, you'll need to flash a stock ROM that has been compiled for flashing in Odin. Don't use any of the ROMs from sammobile.com.

Wouldn't it brick my phone?
Wouldn't this brick my device though? I have the MJ2 Bootloader and I never updated OTA to 4.4 Samsung Stock. Reading through those posts gave me the feeling that the method stated would brick my device.
EDIT: Well I just hard-bricked.

Which bootloader did you have? The first post said MJB, the second said MJ2.
With the MJ2, I believe you could have flashed back to stock 4.1.1 and just run OTA updates until you hit 4.4.2.
MJ2 is the leaked bootloader: http://forum.xda-developers.com/showthread.php?t=2498233
Travelling in the Philippines and my wife's rooted 4.3 N900T (otherwise stock and Knox 0x0) is having issues with keeping cellular lock (Globe) and WiFi lock. Both signals drop periodically whereas my own N900T running Effortless rev 7 (4.4.2 NF4) is rock solid. Given that the phones are identical and she didn't have his problem prior to travelling I am assuming this is related to the older radio FW on 4.3. I'm looking for a fix with minimum changes to the phone (don't want to risk screwing up the phone when it is sometimes functional, limited tools on hand and very slow internet speeds). My initial thought was to do an OTA update to 4.4.2, but since the phone is rooted it will not allow this. I then looked for guides how to go from 4.3 to 4.4.2, but most threads assume 4.4.2 is already installed. I'm looking for advice how to fix the radio / FW problem. Open to flashing just the radios (does that trigger KNOX?) or doing OTA updates (unroot and wait for OTA or download and sideload files?). Any suggestions are welcome.
Found this regarding WIFI issues on 4.3. Trying turning off power saving and scanning to see if this helps. Would still be interested in advice regarding updating to 4.4.2 via OTA and if I can flash newer modems without triggering KNOX while remaining on 4.3.

Thanks for the reply.
I have seen the effortless guide, but it assumes odin'ing a stock NK3. I can do this as a last resort, but I'm assuming the safest way to do this type of upgrade would be to start with stock MI7, then do the OTA to 4.4.2 so I get the bootloader, then do the NK3 or OTA up to NK3, then follow the rest of the guide? In this process I would need to backup my data e.g. using TI backup and restore later. Was hoping someone knew how to unroot manually, e.g. delete su files?, so I can OTA up to NK3 w/o doing the back up. Or would the latest modem or some newer version higher than the one from 4.3 work with 4.3 MI7?

I picked up a used AT&T S3 here in NY because I just installed an Alpine ICS-X7HD in my car. The S3 had the latest NJ1 installed. I was able to root the phone OK. My research has lead me to believe that I won't be able to get any version of Drive Link running on Android 4.4 without FCing when connecting to the Alpine Unit. Research also seems to suggest that I can't go back to the LK3 version either due to boot loader changes made from Samsung and AT&T with the 4.3 update. So I'm looking for advice from the forum experts on what I can do, if anything to get the phone downgraded to a Jelly Bean firmware. I am hoping to hear from someone who has been able to do this before. Can I go from 4.4.2 to 4.3? If so does Drive link still work for you?
I am comfortable using Odin and adb. Let me know if you need any other specific information.
The solution was so incredibly simple. I flashed the AT&T+UCMG2.ZIP through TWRP and rebooted. Now I am on 4.1.2. Drive Link working! So To Recap...I went from 4.4.2 NJ1 back to 4.1.2 and stayed on NJ1 baseband.

How did you root on Nj1??!
To get to jelly bean, you do the hack like method above by flashing a zip in TWRP or Clockwork mod or boot a custom rom based off 4.1.x. Once you are on 4.3 or 4.4, there is no going back to a previous version, attempts result in bricking.
It's been a while since I flashed a rom. I thought I would play around with some ROM's today, but I'm getting overwhelmed by the contradictory information out there, regarding bootloaders,wifi patches, kernel flashes etc. Not that it's misinformation, but I just don't know if it's implied that the bootloader on the install instructions have been updated to 4.1.2 or higher before moving forward with flash.
I'm on a rooted T-mo/T889 Galaxy Note 2 with stock 4.1.1 and UVALL4. I flashed TWRP on it a few months ago, when I was looking into installing DN3 rom.
It seems to me that the instructions for installing DN4 (which is what I'm looking at today) might assume my device is updated to latest firmware.
So I'm wondering where to start. Do I need to update bootloader, or can I just move forward with electronteam's install instructions flash DN4 with addon patch? Or even more broader terms, can I flash a 4.4.4 + rom from a 4.1.1 firmware?

You're good to go with DN4... just flash Dn4 and addon. The only thing is, Dn4 has issues with GPS. So, if you need/use this often, you may want to stick with DN3. Oh yeah, update your TWRP to newest (2.8.5.0) since it's been a few months since you installed it. And after you get it set up, update to the newest Agni kernel... http://forum.xda-developers.com/showthread.php?t=2602053
Thanks.
I went ahead with DN4, and sure enough, I have no GPS.
A more troubling issue I'm having is that my data/phone signal just randomly gone. I live in a city with LTE , and have no coverage issues here. Sometimes a restart will remedy it, but only for a short while. I'm going to flash this Latest Agni, Maybe that will fix it. EDIT: Nope, still happening. Changing Network Mode back and forth between LTE and WCDMA/GSM seems to be easier than rebooting though.
