Okay folks I'm a newbbie here so take it easy. By trade I'm a hardware guy not a software guy by any means. And yes I've tried to google this and can't find a straight answer. Okay so after reflashing and bring a buddy's phone out of a soft brick and rooting it , i would like to do it to my my note 3 sm-n900a att phone. I know there is no real root option for KM NC2 due to the bootloader and i know i can't roll back to jelly bean which i like a hell of alot more. Kk with att has **** of a lot of bugs as far as i can tell. Anyways over the past week i managed to get MLG on the phone but still can't roll back. Bootloader is A3. After last night I got CSC to MI9 everything else is MLG. What I was thinking about was reflashing to SM-N900T firmware NB4 and rooting from there. Would this be possible to do or would the NB4 software jack up the phone as far as service or anything? Or would there be something else I would need to do along with this. I was planning on going back to a NC2 based romantic after wards. Extream Kat might be my choice. I just need to get to root to do safestrap.

Hello Guys
Well, let me get straight to the point. After my old rom (Revolution HD3) was draining my battery pretty fast, i decided to update to 4.4.2. Well, i downloaded the latest 4.4.2 for switzerland from sammobile.com. I flashed it and it somehow was all laggy and i had fc's the whole time. After some time i was able to use the phone anyway, but it was laggy. And the problem was that my 3G connection was EXTREMELY slow. I got connection time outs the whole time and wasnt able to download anything. Well, i thought it was the rom i flashed trough odin, so i downgraded to 4.2.2, my original rom, and updated trough KIES. The rom wasnt laggy anymore, but the 3g/4g was slow. I tried different Modems and Kernels. Nothing Helped. I then decided im going back to a custom rom but the flash failed. Then i tried another rom and it failed again. So i thought it may was cause i was on 4.4.2 and tried to flash a custom rom that was 4.2.2. I then tried to reflash my stock rom trough odin, and it FAILED. And that's how i bricked my phone. I can still enter Download Mode, but can't enter the recovery anymore. What do i do? I'd like to solve both problems.
Thanks guys
Btw: I've got an I9505
I assume you didn't wipe anything before you flashed stuff? Thats like rule number 1 to do.
You can try flashing a recovery true Odin.
Hej Guys
Um.. Just to let you guys know, it is possible to downgrad to 4.2.2 from 4.4.2. I just did it this morning and had sucess. But the problem with the really slow internet connction still is here, when im on a 4.4.2. And, it is the same with custom roms running 4.4.2. I tried different kernels and modems, nothing helped so far. As soon as i was back to 4.2.2 it had the usual connection speed. I called my provider and also called samsung itself. Obviously, they both told me to bring the phone back for garantuee. But well, as i know it's a software problem and not hardware, i wont do that. So can you guys help me? What should i do next? Actually im back on 4.2.2. Thanks
Edit: Oh, and ofc, i did everything like wiping/factory resetting, wipping preoload etc. It's not my first time flashing.
It's not possible to downgrade from 4.4.2 to 4.2.2! End of..

Are you serious dude? Im running 4.2.2 right now. What is your point?`I didnt even ask about it. I asked about a solution to the problem that i get slow 3G/4G on my I9505 when running 4.4.2. If you want a proof Pic about it running 4.2.2, i can give you one. But i dont really get what your point is.
Hang on hang on hang on, it is common knowledge that you cannot downgrade from official samsung 4.4.2 to official samsung 4.2.2 because in odin you will get failure at aboot.bin because you cannot downgrade bootloader.
How ever what would be really good is instead of just trying to say it then jumping out saying what's your point, we'll my friend the point is, it would be advantageous to everyone in the entire samsung galaxy s4 i9505 community if you can tell everyone how you did it.
My perspective is your doing a bit of flaming.
Pictures really won't prove a whole lot as anyone can do some build.prop edits and show different rom name and version.

Well, if it sounded like flame to you, it wasnt. I didnt create this thread to flame others. But i wasnt kidding saying that i downgraded to 4.2.2. Here how i did it:
Was running 4.4.2 (I9505XXUFNB9)
Flashed TWRP recovery.
Flashed custom Rom 4.2.2, which FAILED!
Flashed Official 4.2.2 trough odin, which FAILED!
Flashed TWRP recovery again, since it was somehow damaged from the flash before
Flashed Wanamlite 4.4.2
Flashed Custom Rom 4.2.2
Flashed Official 4.2.2 with succes.
Im not sure what part of those flashes were essential, but i have no reason for liying to you. What would be the perks if i did?
But now again BTT, Did anyone else have that problem of slow interenet connection? Or is it just me? Maybe some ideas?
Regarding slow Internet maybe it's your carrier with issues.
Maybe the downgrade back to 4.2.2 has created issues in its self. Have you checked your baseband matches bootloader and build?
A problem we have is we can't see the version of the 4G modem (non-hols) so that might be also an issue.
When you flashed back did you do a factory reset?
In regards to downgrade do you still have the Knox bootloader?

Well, i called my operator and the girl on the phone said that some people already called with the same issue, but its not on their side. It's a problem with the update samsung released. After the downgrade i had my Knox Bootloader and everything worked like it always did.
Yesterday Sammobile released a new ''rom'' for my country. Downloaded it, flashed it and it works great now. I have a bit of a fast battery Drain, but the problem with the slow internet seems to be fixed.
Again: 4.2.2 worked perfectly after downgrade. It had no issue, No FC nothing at all. Maybe i was lucky? No idea, but im happy my 4.4.2 works now
Thanks anyway for your help guys
Edit: Yeah, my bootloader matched both baseband and build.

If you had done your homework, you would know that in almost all cases Samsung repairs it even with Knox set to 0x1. They even publicly stated it in the Netherlands that they will repair your phone even with custom roms.
And you don't know the law in Switserland. Nor do I. So you can't say that in Switserland his rights are voided by flashing.
If Samsung doesn't give you the warranty, then you still have your consumer rights in the European Union (not that Switerland is in it). No flashing, modding or other chances decleine you your rights if it's not related to a hardware failure. In the countries that you and I live in, it will never void your rights if the damage is not related to flashing or modding.
So well, i think that in switzerland they actually WONT repair it if you flash it, but i aint sure about that, since i never had to send it to repair. But anyway, it was only a software problem on their side. They released another version for switzerland and it seemed to have fixed the problem. I have a bit more of a battery drain, but i actually think im just too used to some other custom roms. Anyways, thanks for the help guys
I got my S4 about a year ago, and it came loaded with MF9 / 4.2.2. I rooted it and added the hotspot hack and have generally been pretty happy with it. I know there have been a handful of updates in the past year that have likely introduced new features but I know there are also new restrictions. I keep wondering if I'm missing anything significant by not upgrading. If I did, I'd probably err on the side of caution and go straight stock NAE.
So, any good reason to upgrade? I've been away for quite a while so appreciate your input.
Do you have knox? Cause if not never upgrade.. If you do.. No reason not to upgrade
Nope, no Knox, which has been my major hesitation because I know there's no going back. But I'm also falling further behind while stuck at MF9, which perhaps isn't such a bad thing, but I get antsy knowing there's been several releases since then.
My bootloader is mf9...But all my software and modem are up to date.
So i have android 4.4.2 and NAE modem.
So i am away from knox. All things are working well.
But i want to flash the full stock via odin and trip my knox counter since I will root my phone and also can flash custom recovery but the only thing i will miss if i decided to return to previous version of Android i can't do that.
So i won't see behind. I will flash anything new.
U have the holy grail of sgs4s dont go and ruin it. Keep bootloader flash twrp and rock a custom rom. Updates are only put out to destroy you and rape your gf.. Your not missing anything. To my knowledge bootloader being old only limits the STOCK roms you may use. (please c9rrect me if jeeded)... In my experience in 33 years i have never gained anything by upgrading a firmware on anything phone psp xbox router u name it.. Nothing but loss of hackability
Has anyone used the towelroot method to root? I'm still on JB firmware (BTU MK2) with root and knox 0x0, im wanting to upgrade to KK but im not sure of which course of action to take.
I'm thinking of installing a pre-June KK firmware but im not sure which one to install (region doesn't really bother me as long as it's english and not AUS). What do you guys think, any advice?
I'm tossing up between flashing the XSP NE4 rom or the BTU ND3 rom and then rooting using towelroot. Has anyone had any issues with these 2 roms, especially battery issues?
Towelroot preserved Knox 0 for me and it was pretty painless, twice already, MI7 to NF4 and now to NF9, so yes it works great at least for me. In my case battery sucked really bad after each update, but it was suggested to me to do full factory reset, as this supposed to work for many. Instead I decided to do exactly what I root my phone for, freeze/delete useless factory bloatware. It worked after first update, I'm still working on it after second, since I just did it couple days ago. On the other hand I'm not sure those updates are even worth the trouble, not much new that I can see, mostly internal stuff. Also originally I SIM and region unlocked my phone using Chainfire program, but I think all that is gone now and I don't think there is new unlock method, so I may regret this update in the future if I travel. And then there is this SD card nonsense that can show up with older programs, so frankly I don't know, choose your poison, but again, towelroot works fine, the question is: is it worth to upgrade.
Hello XDA. I am going to unroot and return to stock firmware and recovery as i would like to update the phone through samsung kies. As i understand i need to update the boot loader and modem. I then plan to reroot and install ktoonz recovery and get a newer rom. I have an SM-g900w8 (telus) currently running x-note NE2 software version 3 i belive and ktoonz 08.04.2014 kernel with twrp 2.8.0.0. I rooted the phone 3 days after i got it and never took a samsung update. I am just curious as to weather i need to revert to stock recovery before i flash the stock firmware. I made a brick out of my S2X trying to revert to stock so i am a little gun shy. Also wondering if this whole coarse of action is advisable and worth the trouble. If there are any known issues with rooting and flashing after samsungs latest updates. Also if anyone can provide or point my toward the stock firmware for a telus sm-g900w8 that would be great as i cant seem to find a reasonable place to download it. i apologize for not doing more reading and research but i just spent 6 months away from home working so i am trying to catch up. Thanks again XDA any help info or criticisms are appreciated .
Hey Guys,
today i got a Galaxy s4 black edition and there is a ROM called: Phoenix Rom. So i want to flash back to Stock ROM but im really not sure which one i want to flash on it because i dont want to brick my phone or something. Can i flash this http://www.handy-faq.de/forum/galaxy-s4-i9505xxugng8-kk-4-4-odin-kies-dbt-1t-23-07-2014-t306745/ without any problems?
Phone: GT-I9505
Basisbandversion: I9505XXUGNG8
Buildnumber: KOT49H.I9505XXUGNF1
That ROM will work without a problem. However, that may not have the added wallpapers and sounds the black edition devices have. Is there a reason you're not wanting Android 5.0.1 on your device?

Thanks for your Answer, i flashed that rom and it works perfectly. There is also an OTA update for Lollipop but im not sure to do that because i heard that lollipop has a lot of bugs like battery draining and so on. Im afraid if i upgrade it to lollipop i cannot downgrade it to KK. But do u think i should update?
I'm inclined to believe Samsung patched the battery drain bug, but you'd have to try it and find out. If you end up not liking it, going back down to the earlier version shouldn't be an issue, especially as you already have a Knox-enabled bootloader on your S4. There are tutorials on the forums here that I believe walk you through the process. Take a look at them before doing the OTA update.

Is it really that my knox bootloader is enabled or not if i do the OTA update? And how can i see that it is enabled or not? Anyway can i root my phone if im on lollipop with CF auto root trough odin ?
You installed Android 4.4.2. 100% positive you have Knox, as all Samsung firmware from 4.3 on has it. Installing the OTA update will restore the Knox apps. Fortunately, CF-AutoRoot still works so you'll have no issues rooting if you install the update.
Ok thank you for your helpful advises, i will flash a kernel on my s4 to stop this overheating issue.
