[Q] downgrade to custom 4.3 over stock 4.4 possible?

hey guys this is my first post and i looked forum and didn't see any information about downgrading on 4.4 to 4.3 . i saw some guys saying its not possible but i assume they mean official downgrade. the thing is i got n9005 with 4.4.2 installed and iam not happy with it so i want to downgrade it to unofficial 4.3 roms. as i understand boot loader changed with 4.4.2 and doesn't allow to go back but what if we can install new bootlader and official ROM. is that not possible too?
2nd q is 0x1 means void warranty what about 0x3 (they say tripped) is this something real or i misunderstand this?
3th q is can i even if i downgraded custom 4.3 and want to go back to stock rom is it possible?
i don't want posts saying its already inside of forum. i just want straight answers.

1. No.
2. Misunderstood, you only trip Knox once.
3. You can always flash stock rom back but sometimes need pit file for carrier roms as hidden partition sems bigger...
Straight enough?...

anything new about downgrading from 4.4 to 4.3?

No. Still can't be done.

SM-N9005 Downgrade 4.4.2 to 4.3

Hi guys, I have been searching everywhere in order to know how to downgrade from 4.4.2 back to 4.3.
However,all posts were telling that once we have updated to 4.4.2....there is no way on downgrading.
So,even the Samsung center can't help me to downgrade too?
Because Im thinking to go over Samsung center to downgrade if they can really do so.

you have a big risk to brick your phone
I read somewhere that someone do it but everywhere it's recommand and it said that after upgrade to KK, no way back

Won't happen. The only way to downgrade a snapdragon based note 3 is to replace the mainboard with one that has not yet seen kitkat.
Sent from my leanKernel 3.4 powered stock 4.4.2 (NF4) SM-N900T

hell...i juz received the 4.4.2 update and start facing so many issues especially the sd card file permission..
It did hav solution but require root..so i thaught maybe reverting to previous version will do..
But now, my note 3 is hopeless and wondering if samsung will release a fix for this ;-(

Well, It can happen now. It may be a little too late for many who might have moved on to newr phone by now. But as a new n9005 owner I struggled hard to downgrade to 4.3 without any issues. So by trial and error I managed to do it taking cues from the original post in another thread. My reason for the downgrade was better battery life. But that did not happen after downgrade. AT least not in a significant way.. Anyway here's my strategy in summary for those who want to downgarde to 43 with no issues. It worked for me. IMEI ok, video recording ok. But I give no guarantee for others. I am not allowed to provide links so will just provide enough clues to loacte them.
Here's what I did:
Again to remind use this is to downgrade N9005 FROM 4.4.2 TO 4.3
The starting point is 4.4.2 rom version N9005XXUGNG1. I had N9005XXUGNG1_VFGGNH1 if you have Android 5.0 first downgrade to this
1. Do A Wipe Data Factory Reset and cache partition
2. Odin: Flash In AP the file "COMBINATION_FA43_N9005XXUGNH1_N9005OXAGNH1_267031 2_REV00_user_mid_noship_MULTI_CERT.tar.md5."
3. Odin: Flash In AP a JB compatible cwm/twrp (look up in this forum) recovery for N9005
5. Boot into Recovery and do a Data/Cache/Dalvik wipe
6. Install in recovery Omega Rom 4.0 for N9005 JB 4.3 (N9005_Omega_v4.0_XXUDMJ7_md5_A7256B2A7F2E7005A65A 6E1CA5EA77C9.zip
7. Done! you will be running a fully working Jelly Bean 4.3 ROM!
Search google for the download links for the required files in 2 and 6. I got them form google search

Thanks InSenex! Would it be possible to flash a _stock_ 4.3.x ROM after the procedure described by you? Omega is a custom ROM, or am I mistaken?

Omega is custom rom.

Its a stock based touchwiz custom rom. Its tweaked stock rom. Its not a custom rom like cm, aosp, aokp etc. Those wishing to desperately downgrde to 4.3 probably would not care about tweaked stock rom or original stock rom

Omega is STOCK based touchwiz tweaked rom. I believe you can make it a pure stock rom by stripping off all the optmizations/tweaking done to it, replacing deleted stocke files from an extracted stock rom, or flash a cwm/twrp flashable jelly bean stock rom (Not sure if it exists, but there are guides on how to make a flashable stock rom)

Original question answered correctly .
<Omega is a custom ROM, or am I mistaken? >
Its a custom rom .
Based on Samsung firmware yes .
Thats why its in Android Development section .
Please be carefull of giving users wrong / confusing information .

[Q] Should I update from 4.3 JB to 4.4.2 KK ?

Hello
I recently got my S4 i9505. I'm planning to root it
I have Android version 4.3
I used to flash costum roms on my s2 but I'm not really planning to do much flashing on my S4. not soon anyway
So as I connected the phone to Kies to make sure the drivers were downloaded so I can proceed with rooting
Firmware update popped up
I'm not sure what the best option for me now.
Should I root now and then I'd be able to flash a costume KK rom? and are there any stable ones that are better than the stock?
Can I use kies to update my rooted phone?
Maybe I should stick with JB 4.3? Which one is better 4.3 or 4.4.2?
I remember facing some issues when I update my s2 back. So I searched for the KK Update for the s4 and some people weren't so happy with their KK update
I know that doesn't represent the majority but still it could happen to me
So I confused myself
What is your advice to me?
sorry for the long post
Also I have an extra question What is KNOX? and do I need it?

First, the most problems in 4.4.2 are fixed, so if you flash the officical, latest firmware of your country you shouldn't have any problem.
An important thing: if you flash a custom rom, your warranty will be set 0x1, that means, you lost your garanty if you flash a custom rom, that's the so called KNOX. You can use knox like a second system on your phone, with all secure data in it, you can only access with a passwort and all datas are locked without this passwort.
Root your phone after the software update if you want to root it.

That's wrong, just not with towelroot.

thank you for your input

So, i just got a S4 with 4.3 in it..

and i wanted to ask a quick question, i am intending in the future to root it and maybe install GPE roms in it, should i just leave it at 4.3 and avoid 4.4.2? i read that downgrading and installing recovery is hard .

Guys waiting for reply please to help

No there isn't. Why would you even do it?

He wants to downgrade the modem so he can unlock his phone. He asked a similar question in the S4 unlocking thread, which he really needs to read if he hasn't already done so.
