[Q] Safe Procedure to Downgrade from 4.4.2 to 4.1.2 - Galaxy Note II Q&A, Help & Troubleshooting

Hello all XDA members especially in our beloved Note 2 community :good:
I've owned my Note 2 since it's first launch.. I'm satisfied and proud to have one of the best phone ever made from Samsung. :good:
I have questions related to downgrading process, just want to confirm the process coz I don't want to brick my Note 2.
My mighty Note 2 is on Omega V.28, 4.4.2 Android Version with MJ5 bootloader and latest TWRP. I want to downgrade to 4.1.2 as I missed the 4.1.2 balance among performance and battery life.
My question are :
1. Can I just flash Omega V.18 (4.1.2) or the others 4.1.2 custom rom (not interested in stock rom ) directly from TWRP ?
2. Won't that procedure brick my phone ?
3. Will I lost my imei and signal ?
4. Can I flash existing modem to fix lost imei (XXUENA) ? Will it compatible with 4.1.2 (Omega V.18) ?
Thanks all for the answer an comments.. :good:
Cheers for Note 2

As long as you are on MJ5 bootloader you can flash 4.1.2 custom ROM via custom recovery.If you lose signal flash any of the modems either from hurricane modem changer or your current one if you have a flashable zip file for that.

I used to be on JellyKat v2,v3,v4 ever since i rooted my note 2.When official KK released i wanted to stay close to stock so i tried phantom v1 then and then for all s5/note3/note 2 looks i am using DN3 V5+.I do switch to AOSP roms in between when i get tired of TW.For now DN3v5+ is what I've been using .

[Q] How to update from 4.1.2 custom rom to 4.2.2 or higher

Hi Everyone,
I do know how to flash a new rom however I had issues flashing from stock 4.1.2 to custom 4.2.2 before (device wouldn't pass the boot screen). So do I have to be on a specific 4.1.2 rom to upgrade or I need to upgrade to a stock 4.2.2 first and then upgrade to a custom one?
Please recommend a fast 4.2.2 custom rom. I would like to keep dual sim feature if possible although I know most roms only support single sim.
My current rom info:
4.1.2
Baseband: I9082XXAMC4
Thanks in advance.

simple one line if want dual sim,(stock based roms only)..u can install stock rom 4.2.2....or balliboxers GENNXT rom based on latest firmware...
NOTE: RAM USAGE OF STOCK AND STOCK BASED ROMS IS HIGH....SO LESSER MULTITASKS HANDLES!
if u can compromise with dual sim ..then u can install slimbean roms...(as u mentioned u want lightest and fastest)... but as they are small and fast, they dont have many extra feature lik halo..bt are lightweight..less ram usage...
bt i wonder why u want 4.2.2 rom when u can installl latest kitkat 4.4.2 (cm11,slimkat rom, carbon rom)..
they all are kitkat roms..........
with cm being a base rom for every rom and a light good rom...so is slimkat...and carbon with good future updates including halo features....
if u still wanna stick to 4.2.2 ....then u got slimbean rom...cm rom....(both dont have halo feature),.bt light...or u cn have PAC,resurrection remix rom(for halo multitasking)...
(gaming is better on kitkat roms)
its all ur choice....
if u want any qsns u can ..
hope i helped ..

First of all, thanks for your awesome reply
Basically I'm on stock rom without useless Samsung apps. Instructions for Pac/resurrection says I need to be on stock rom in order to upgrade to 4.2.2. So am I ok to flash their rom or first install a stock rom?
You mentioned kitkat roms are better and I agree, however based on instructions I need to be on 4.2.2 first before upgrading
Which recovery is the best for making nandroid backups? clockworkmod seems to have issues occasionally creating bad backups.
Kitkat roms seems to have app2sd enabled by default, right? and no issues with Xposed framework modules?

xposed is working fine on dalvik runtime(as google introduced new runtime with 4.4 named ART ,WHICH CONSUMES LESS RAM, BUT IS UNSTABLE)...
when they say that u need to be on stock ROM 4.1.2 , they actually mean the 4.1.2 bootloader..so its okat if u are on GENNXT ROM...stock..abit modified stock 4.1.2...(they specifically mean that if u want 4.2.2 rom, be on 4.1.2 bootloader...and if u want kitkat rom..then be on 4.2.2 rom(any stock based 4.2.2 rom like gennxt or slight modifyd 4.2.2 will do , as all they need is 4.2.2 bootloader for kk roms to work)...if u want kitkat rom.....be on stock based rom..which are touchwiz based roms of 4.2.2)....
so flash 4.2.2 rom by odin..and den install kitkat...if u face any problem ....just pm me ...and ya..
always do wipe cache,dalvikcache and data(if told) , whenever u flash anything(before and after flashing)... u can ask any qsna u wanna ask..hope i helped.

one question from my side as well.
I am on stock rooted 4.1.2 rom and I want to upgrade to stock 4.2.2 rom. what would be the best method?
can I install 4.2.2 latest version by flashing via odin directly or do I need to unroot first?
or it will be automatically unrooted when I install 4.2.2(stock) latest over my 4.1.2(stock) by odin?
I hope you got my question.

I finally got the chance to upgrade to stock 4.2.2 via odin and gaining root again. However I was unable to install kitkat. Even though I wiped cache and did factory reset, boot didn't pass the samsung logo. I still have 2 sim support, is it worthed to install kitkat? According to your previous instructions, I needed to be on 4.2.2 base in order to upgrade to kitkat. What would you suggest in my case
Thanks

I am a heavy gamer and performancive device addict..
Kitkat dont have any fancy samsung stuffs bro..bt its all system files are of kitkat so the gaming performance is alot increased.. All game bugs are almost fix which were in 4.2.2......there is work around for every thing..
I mean..think about it..
I never use smart stay...
I nor did use much of live wallpapers as they were battery consuming..the lock screen was fancy but still lets face truth that its just meant for security/unlocking screen ...u will have to compromise with single sim and non fancy apps ..
But it does worth a try..i mean why not ... Give it a shot and i am sure u will find something unique about it...
It got its own features..so ya...its ur wish..there are also downsides of it .....u can check respective threads and know more..
Hope i helped

Ok bro, I installed selinux cmw recovery... downloaded CM11... I noticed CM is about 200mb comparing to 1 GB stock 4.2.2. Does that mean I will get more free space on internal sdcard? (out of 4GB I mean)...as others suggested, I need to do full wipe/reset factory and manually format system? and if update wasnt successful I can go back to stock via Odin right?

[Q] [TUTORIAL-REQUEST] Note 2 Stock 4.3 to get Note 3 Features.

I currently have my note 2 on stock 4.3 without root and i want to get the Note 3 features in it.
My firmware goes like N7100XXUEMKA_N7100OJVEMK3_XSG. from http://www.sammobile.com/firmwares/3/?download=23540
Last time i tried was, root-->wipe-->factory reset-->flash this http://forum.xda-developers.com/showthread.php?t=2467810
But that gave lot of crashes on homescreen and i couldnt use it. So the question here is, is there any way i can get these features and still run official stock? as seen on http://www.youtube.com/watch?v=Xcg7vgcJwW8 . Or do i have to go with flashing either Dr.Ketan's Custom ROM V6 Deodexed or DN3(Ditto Note 3) ROM?

For this mod you need a DEODEXED 4.3 XXUEMK4 based Rom. The only way is to root and flash the mod over it. Or you can flash a custom rom where this mod is includet.

else if i were to flash a custom rom, between DN3 and Dr Ketans Rom which one would you recommend?

I have not flashed DN3 yet. But i am very happy with ketan's rom. Deodexed roms can be found in android development section. There is one pure stock but only deodexed and rooted from doctor ketan. It's in android development busection. And S3 features are working.

N7100 on LK7-bootloader - what to do for 4.3?

Hello,
I've got a LK7-bootloader (baseband N7100XXDLK7) on my german N7100 and actually installed ProBAM 1.2.0.
Because of some stability-issues I would like to install a 4.3-ROM like Omega or Phoenix, but I'm a bit confused about MJ5-bootloader, KNOX, Wifi-Fix etc.
Under all circumstances I would like to avoid having a KNOX-actived bootloader!
What do I have to do to get a smooth, stable 4.3-ROM with the corresponding bootloader?
Any help is really much appreciated :good:
Best regards and thanks a lot
cool400
You can either remain on your bootloader and flash Dr. ketan's Wi-fi patch, or flash MJ5 bootloader, which doesn't have Knox. IMHO MJ5 is better option. I have flashed Criskelo ROM (4.3) and MJ5 bootloader weeks ago and it works just perfectly. Definitely smoother and faster than 4.1.2, battery is the same, 100% stable, never had a glitch, and Note 3 pack is great.
Hi guys u guys are very helpful to each others
My problem is I having n7100 bought in China(somebody bring from there) I don't know which version I tried to install cynogen os year back successful done after bored with CM10 then I installed N7105 CM12 successful then t889 version CM13 (I LOST IMEI) I tired to fix IMEI but fails..
Now I tried stock ROM t889 successfully installed i got my IMEI back but T mobile locked SIM
Now can i install international stock ROM ?
Which bootloader I have to install?
Now I want my phone back to work
What to do which is best?
My bootloader mk7
Thank you everyone ...

[Q] Going back to Note 2 Stock rom ?

Hi,
I have had my note 3 for a while now and am selling my Note 2 so i want to flash the most stable stock rom for UK as i dont want the new owner to have any problems with the phone. Any advise ? What rom should i go for ?
I have been using the 4.3 roms with Note 3 mods and also flashed the newest bootloader to make the 4.3 wifi work so now i am wondering if i am able to go back to 4.1 or 4.2 stock roms without any issues ?
Or if the above is impossible then is there any rom i can flash that don't have any kind of FC's what so ever ?
EDIT: nvm i figured it out. SOLVED
If you already updated the bootloader i think you will be not able to use a rom that is older than the 4.3, but to be sure just ask someone more expert than me

Bootloader 4.4 and Firmware T999UVUEOH1

Hi guys, I have T999 I am on Likewise 4.1 dtmo and currently on the T999UVUENC2 modem/bootloader, which is version 4.3. I have not updated my phone in a while and now I'm searching the forums and have 2 questions:
1. Should I update my bootloader/modem to T999UVUEOH1? I have read that it fixed the stagefright bug. (I found it on sammobile)
2. Some ROMs in the ATT section, such as the S3 R3ARMED, which is also made for T999, call for the use of a 4.4 modem and bootloader, but there is no such thing available to us. How can I proceed to avoid a brick?
Thanks!
I just updated it and there is nothing new. Just keep calm and stay at NC2, i will test it's performance and battery life
