[Q] (Noob?) question - stock 4.3 to custom 4.4 rom

I've been trying to figure this out for the last day, with no success.
I've got a rooted Note 3 N9005 (MJ7) stock. this is a 4.3 Rom. Knox status is0x0 (didn't trip it when I've rooted it ages ago).
I had enough of sammy rom, and I want to play with some of the new 4.4.4 custom roms.
I'm totally and utterly lost regarding what's tripping knox, and what are the needed steps in order to achieve that.
From what I understand, flashing TWRP (or any other custom recovery) will trip knox. I'm fine with that.
I'm not sure if I'm supposed to first upgrade my 4.3 to an official 4.4.2, and what / if is all the lock/unlock bootloader which seems to differ between versions (4.3 and 4.4). There also seem to be different versions of TWRP depending on if you're on 4.3 or 4.4?
Can I simply flash TWRP on my rooted 4.3, backup, flash new shinny 4.4.4 rom, and be happy ? Will that keep the root ?
Otherwise, do i need to upgrade to official 4.4.2 version first? will that lose root and I'll have to reroot the new version, and then flash TWRP and then flash 4.4.4 roms?
Any kind of help (or point me to an article that discusses it, even though I didn't find any, and i've searched) will be highly appreciated.
Cheers and thanks in advance.

If you aren't concerned about KNOX, upgrade to a 4.4 ROM (Official) via ODIN which will upgrade the bootloader, then once that's all done, flash TWRP for 4.4 then download your ROMs and flash via TWRP as normal.

Not concerned any more ...
Out of curiosity, what exactly kills the root? flashing a rom doesn't. upgrading via odin ? I'm assuming it has nothing to do with the system/cache, since each flash usually wipes them, so, where does it live?

Reflashing the ROM back to stock is what kills root. It's easy to re-root again once you've tripped KNOX anyways.
But tbh, once you install a custom recovery after you've upgraded your boot loader, you won't need to root. It isn't required for custom recovery

EDIT: Have you used ODIN to flash stock images before? If not, have a read around, it's pretty straight forward though.

I see ... so -> flash stock (kills root) -> flash TWRP (trips knox) -> flash custom rom without worrying about root ? (wouldn't i need it for titanium backup ,or do custom roms come with SU preinstalled?)
Yep, used odin. file on comp, download mode, couple of ticks, clicky clicky, happiness ensues ...

Yeah you're pretty much spot on. Yeah most ROMs are pre-rooted and if they aren't you can just flash superSU via your recovery. But you should be good to go and know what you're doing by the sounds of it.
Enjoy flashing them ROMs and make an efs backup and store off the device too. There's an adb script for it here (forget where but its here, development thread I think) don't use any apps from the play store as they are notorious for bricking Samsung devices.

lol ...notorious for bricking samsung devices ... i like it ...
i ran one already (zipped a 6MB and a 14.5MB image and tar into a 300kb zip), and been told you can do that from inside TWRP as well ...
I'll take a deep breath, and start downloading the official image and roms ...
I'll update if i'll get to the other side

out of curiosity ... does it matter which official 4.4.2 image i'm flashing ? (i'm getting the NZ one ...but i assume they should all be similar, and / or that it doesn't matter since i'll be flashing something else on it anyways, right ?

Yeah try and keep to the country your device is from, otherwise you have to find the right PIT file, and the partitions vary etc

4.4.2 Update from 4.3 on Galaxy S4 i9505

Pardon the noobishness.
My 4.3 was rooted via towelroot and has Nova launcher,
as I have read for months about recoveries, ROM's, Kernels, bootloaders etc
and am more confused than when I first looked into rooting!
3 days ago I decided to flash my stock ROM so that I could update from 4.3 TO 4.4.2 VIA kies.
Immediately I was underwhelmed!
My phone turned itself off randomly.
The K on the kit katkat screen did not spin.
I lost my root, so I thought I would try and re flash the i9505XXUEMK9. Odin said in yellow "failed".
I waited about 15 minutes and nothing was happening and unplugged,big mistake,
the screen had a yellow picture, oh FUDGE!
So I took it to the Samsung Store in Sydney and I was lucky enough that the store was empty and a tech came up to me(!?)
I didn't have a reciept, but I told him the story and he said he could help.
He connected it to his laptop and asked me what carrier, and 10 minutes later,
phone was working and he had flash the Optus logo onto it
I was so happy!
When the phone booted up there was the towelroot and Titanium apps on the screen, but he didn't even care
I take it home, towelroot doesn't work, so I investigate, and the answer is Chainfire, all good.
The stress of it all!
Then I decide to hell with a custom ROM, I found Xposed with Gravitybox
and spent all arvo trying to make it work and Nudda!
Are my dreams of custom ROMS over??
As I am really wanting a hybrid S5 ROM!
I'm so lost!
I back up with titanium. I don't understand why I would need CWM, TWRP or Philz?
Then, the wiping process, dalviks?
Then I know how to flash with Odin.
I would really appreciate if someone knows a comprehensive tutorial or just to be pointed in the direction of my
knowledge blackholes, I feel that I'm close to being full circle!
I really want the S5, Note 3/4 features but I can't afford the upgrade.
Any advice or comments will be appreciated

Indeed, based on your story you are a big noob (no offence). You tried to flash a 4.3 rom while you were already on 4.4.2. That's impossible.
So what do you want? A custom rom?
- Flash a custom recovery
- Flash the rom with the custom recovery
It's so easy.
And Gravitybox? You should read more. That's not for a TW based rom. It clearly states that in big letters.

Thanks
Thanks for stating the obvious Lenny.
I want a hybrid S5 Rom.
Do I just have to download the ROM then flash it?
I don't understand why I couldn't just re flash 4.3?
Thanks

Yes download and flash.
If you want to know why you couldn't reflash 4.3 read this.

OK.
I have flashed CWM 6.0.4.4.
I don't see the point of that though.
Next is to download a custom ROM and flash that?

I recommend you flash TWRP or Philz Recovery for avoid problems.

Was on custom rom, flashed another and now bootloop.

Hey guys, I'll keep it short. I was rooted, installed TWRP, running Simple Rom and was just feeling to flash erobot. Flashed it doing full wipes and then rebooted, cool. Got to the samsung logo and within a second back to the note 4 screen. Okay I said, maybe the file I downloaded was corrupted or I installed it wrong. Did it over again, this time trying a few variations in the aroma installer (not installing xposed) thought maybe that was the problem. Bam same issue.
No worries I still had the old simple rom on the sd card. Went back with the same install and what do you know, that rom is now in a bootloop as well. Tried flashing through odin but I always get a nand write failed to start or something like that. Tried 3 different usb ports and same issue.
Am I missing something? Any advice would be greatly appreciated.

So you are using the Exynos model? Last I checked there is this OJ5 bootloader which can't be downgraded from!

Yes I'm on the exynos model. So what did I do wrong, I went from lollipop to a lollipop rom. I didn't go back to KK or anything. What do I have to do?

guys help me im having bootloop because i was trying to install the su suser .in my note 4 Note 4 N910C lolipop in tw recovery still boot loop? because i want to root it .send me a maasage thank you

Anyone?

Did you flash a kernel for your variant after flashing the ROM?

No but that is my next move today, had a feeling it might be the problem, I'll try it and report back.

Oj5 bl doesn't let the flash of older rom even lp 5.1.1 older then oj5 but erobot 12 and 13.4 are newest then oj5 so it must be something else like the supersu v2.65 have issues with some costum kernels try to flash v 2.45

Had the same problem, solved it by flashing cf auto root using ODIN.

can't you just flash the previous rom again??
Enter your recovery and flash your "old" rom

No IMEI, Baseband,and Signal after Downgrading to Stock KK

So I had DarkLord N5 on my N9005 before, which was awesome, but it had performance issues (especially when gaming). Then i downgraded to Stock KitKat using Odin and after boot up It showed No Signal, and everything was freezing and force closing. I somehow went to settings and found that i also have issues with IMEI and Baseband version, it was all unknown. The worst part is i did not backup my EFS. Any help guys please :crying:
I also have no audio playback

Im no pro here, but as i found in my research it is hard to downgrade from lolipop to kitkat as in 5.0 new architecture has been presented which they called art. I think. So it gives lots of incompatibilities. I tried the same as you but i ended up going stock lolipop for a while.
Yesterday i flashed Ressurrection remix 6.0.1 Marshmallow based off Slim roms and CM and i admit this is so far best rom i have tested. (Unless you need all fancy spen features)
I'd try to stick to anything that is 5.1 or above since great battery life.
Sorry for not much info, but i couldn't get past your post unanswered.

I had many experiences with downgrading from new version to old version with my S3 and my Note, but never had this issue. Something is causing this...

founded a old backup of CM11.. Flashed CWM and restored to CM. Works flawlessly, but still no sound and those stuff

So i had problems with my either s2 or note 4.
But afaik if u have updated your bootloader there may be no way to get back. And lack of IMEI on reverted KitKat isn't anything new. I bet going simply to anything art. Based will do.
People here are arguing on same issues as yours. Just don't listen to these "flash with odin" guys.. This doesn't work. Even if u flash the stock one.

I tried it, but still no use :c

I would not try any other ROMs before trying to flash the latest stock rom from sammobile.com. Hopefully, this will resolve the baseband and imei issue. Sometimes, the missing or wrong imei is caused by a mismatch between the bootloader and modem firmware.

I did downgrading from 5.0 (CM12) to Stock 4.4 KitKat in my S3, but never had issues like this.

Downgrading from a cm rom to a stock rom via Odin can be fine because installing a cm rom does NOT alter the phone's bootloader or modem. Trying to downgrade from stock 4.4.2 to stock 4.3 with Odin on an s3 cannot be done.

Oh, never knew about this, thanks for the info

Sorry, I meant to say that installing a cm rom DOES NOT change the bootloader or modem. When you flash back to stock via Odin, you are simply writing over the existing modem and bootloader with the same bootloader and modem if you are flashing the same stock rom that was on the phone before installing cm.

I flashed between KitKat and LP official just fine.

Stuck on Samsung Logo trying to reflash some Rom ? (need advice!)

hey guys, this is about the G900H , i just wanted to reflash KitKat based Xstrestolite for my bro.
the v 1.5 based on ANJ2.
and it keeps getting stuck on the samsung animation logo , i have reflashed the modem/bootloader and then tried flashing rom ,did a full wipe.
Note: i have flashed some of the latest TWRP recovery with Odin prior to trying to reflash Rom.
i had philz on it before, i do not know if that affects it in any way though.
it is really getting annoying, do i have to flash a stock firmware with odin in order to get it running again ?
i actually do not care anymore, i just want a Samsung based Rom on this thing that runs well and that is all ! (can be KK/LP/MM just as long as it boots ..)
i'd appreciate it if someone could guide me into how to get something running on this phone again, thanks !

i tried flashing LP with it and i got FC's on the setup , couldn't get past the setup.
do i have to wipe anything in recovery menu after flashing firmware with odin ?

Yes any firmware should work as long as it's for 900h try wiping your user data in the recovery then reflash with odin.
