Seems like your phone is ****ed if you cant use the phone with a stock os. Did you flash the correct modem and bootloader to match the os version ?
I have had a few brinks over time and tried a few stock os's and I couldn't get it back but after 10 different stock os versions I got it back to work normally. I don't know why it is but some times different stock versions can have a different effect on your phone and bring it back from the dead
So you got 2 options. 1 take it to a repair shop as Sammy will charge you an arm and a leg to fix it with the knox counter triggered. 2 Keep trying with different stock os and hope for the best but do remember the modem and bootloader for each version.

last time i flashed the os was from kitkat to lollipop before flashing poprocks os. i have not flashed anything or modded/installed any tweaks within i suppose the month of the phone breaking. i still had the stock os from when i updated to lollipop but it didnt help. never touched the modem besides what the poprocks might have changed. only flashed firekat, stock lollipop, poprocks.

[Q] Flash a 4,3 TW Rom with STOCK Recovey and Pre-KNOX bootloader?

I THOUGHT what I wanted was simple enough but apparently with Samsung nothing is ever simple.
I have the i9505 S4 and am currently on the Pre-Rooted I9505XXUBMGA rom. That means 4.2.2, Stock Recovery and PRE-KNOX bootloader.
My custom flash counter is also 0 as I've only ever flashed the pre-rooted stock kind of roms. No triangle has ever appeared on my screen.
What I want to do is install a 4.3 TW rom WITHOUT flashing a custom recovery (so probably through Odin) and WITHOUT having to flash the KNOX-enabled bootloader.
The reasons should be obvious enough, I want this phone kept as close to stock as possible with what I do being completely reversible without having to rely on Triangle Away as with every new firmware Samsung appears to be even more hell-bent on breaking it.
Obviously I'd want said rom to actually function correctly as I've read things like sound and/or wifi breaking or mobile data dropping with/without the phone being on sleep etc...
So, any takers?

Hi,
From where I am,I can see 3 options.
1.Stay where you are on 4.2.2
You just need to flash stock firmware ,and you are back to out-of-the-box state.
But....you want 4.3.... so,
2.Flash a custom recovery,and you have the choice of every custom ROM in the DEV section.4.22,4.3 ,TW,AOSP , you get my drift.As long at it does not contain the new knox bootloader,you can get back to out-of-the-box state in 2 easy steps:
Triangle Away.
Flash stock firmware.
3.Try to flash the new knox-pox 4.3 ROM and be stuck there.(because there is no coming back)
Look HERE
The [OP] explains it well.
And this is probably the ROM you would choose.(close to stock)
It seems the samsung is determined to mess things up for the user who wants to easily mod their own phones.
It has gotten so bad,that the [OP] has even jumped ship to the Z1.
He says he will maintain that ROM,but for how long,because they have already moved the goalposts twice...
I am on 2.
And I intend to stay there,because I like to be in charge of what goes on my phone.
Devs will almost certainly maintain their ROMS,and updates like 4.4 will come along in time.
Only you can make the choice.
Hopefully,I have given you some options.
Yeah, that's the thread I flashed my current 4.2.2 rom from. I saw him throw the towel and decided this just wasn't gonna work.
I guess I need to take the plunge and install Philz recovery.
Somewhat subjective I know but, which 4.3 TW custom ROM seems to work best when the OLD Pre-KNOX bootloader is being kept and with which modem? (I've seem answers vary wildly on this one).

Hi,
The reason you have seen such wild variations on this,is because it is so subjective.
This is where the fun begins.
Trying out different ROMS,and seeing which is best suited to you,and your requirements.
Best advice...read the first post of a ROM,and see if it has what you want from a ROM...especially the bit about new knox bootloader removed.
And remember to make a nandroid!
As for modem,if you are having no issues or signal problems at the moment,stick with the one you are on.

Slow Internet (3G/LTE) after 4.4.2 Update

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..
Sent from my GT-I9505 using xda premium
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.
Sent from my GT-I9505 using Tapatalk
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?
Sent from my GT-I9505 using Tapatalk
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

[Q] Seriously desperate...

Ready to sell this phone... tried everything I know how to try... Dev Edition Verizon S5, CAN'T UPGRADE from stock NCG. The most I can do it root... any ROM I flash is nonfunctional on Verizon's network with NO SIGNAL. Replaced SIM, flashed modems, etc etc... I think I'm just not sure how to do it with a dev edition... seriously feel like I'm missing a step. Would like to start from scratch. Does anyone have a stock image of a G900V Dev Edition I could work from, since I'm starting to think the one I've been working from is somehow the incorrect version. Thanks!

I would but I'm trying to avoid locking the bootloader, if possible. Didn't intend on having a developer device, but now that I do, I'd like to try to maintain it's use as one. Bought this phone on swappa, seller didn't give any indication that it was a developer device. Now I'm concerned he did something to it prior to selling that is causing me difficulties. I don't think I should be having these network difficulties, but there could very well be something I'm supposed to be doing with the modem that I'm just unaware of. I figure if I can get back to the way this phone was when it was new (when the original seller bought it) I'd at least have a clean slate to work with.

I don't think so, but thanks... I think that's the same device firmware that the retail version comes with, which will lock my bootloader. I've actually considered just flashing it anyway and saying the hell with an unlocked bootloader, since I didn't really intend to have one to begin with and apparently there's nothing I can do with it, anyway (none of the unified builds work on my device, anyway) but this is a last-ditch effort to preserve it if i can, and I'm hoping some dev will be willing to help me diagnose my problem.

It's not like there's a ton of development going on for Dev edition. I'm loving the retail version of the phone just rooted and running some Xposed. Like it so much, I went out and got one for the wife too and I paid full retail for both to keep my old unlimited data plan. Hers I just left out of the box stock. Will be interested to see how Lolipop looks when it drops to her phone. Sure hope we keep root with Lolipop, I use the heck out of my hotspot, to the tune of about 70gb/mo ...

I'm far from a developer, but this may help. I also bought the phone without realizing what it was I was getting into and had similar problems flashing the Optimal rom on my dev edition s5. I could flash but phone would hang on the activation screen with no signal. I eventually succeeded. As near as I can recall this is what I did:
I dirty flashed Beantown 4.4.4 rom (twrp) over my 4.4.2 stock firmware. then flashed n12 firmware (included stock kernel, and modem) from dev edition make an update .tar thread (odin) (http://forum.xda-developers.com/showpost.php?p=56604757&postcount=2). I did a factory reset after flashing. Switched to art. Flashed optimal with clean reset, but did not flash kernel. Later flashed koontsez 4.4.4 kernel. Still running Optimal
Good luck.

Had marginal success using this method... Have been able to maintain a 3G signal, but no LTE after first boot. Rather, when I first booted, I had LTE and thought I was good, but since my first reboot, I can only get 3G and nothing I do can get it back so far.

This happened after I flashed the update.tar (with aboot.mbn removed) and I have note gotten LTE back. Is there something I can do with my aboot.bak that I'm missing?

New around here. Some doubts.

Hello.
Ever since I bought a Galaxy Nexus and found XDA, my life changed. Without noticing I got infected a virus: addiction to Android.
My Nexus got outdated quickly and now is pretty done and I need a new toy. 3,5 years later I finally got some spare money to buy a new phone. Since here in Portugal the minimum wage is around 500€ and top flagship phones cost around 700€ (and there's no affordable contract to get something cheaper and still nice), I had to wait until now to get a used Note 3 for 300€.
I love the phone's design and above all the specs. There's no other phone with 3GB RAM and Snap 800 for this price and I always liked big sized phones.
Well, I write too much unnecessary info... I need to stop
Let's get down to the point. I will get the phone tomorrow!!
TL;DR
How do I check the bootloader version? I want to flash TWRP right away and maybe install a Note4/5 port or something stock Android, do I need to be careful with the bootloader?
I know from other phones (i.e LG G2) that any custom rom uses KK bootloader and the stock roms use their respective version bootloader. Is this also true for the Note?
Also, which version of TWRP should I flash? Does it depend on the stock rom version that I have?
Checking if the device has 2.3x GB of available RAM, if Odin and Recovery have their stock aspect and if the S-Pen works is enough to ensure that the Note I'm getting is truly original?
Well, that's all. I'm sorry if I'm asking the same questions everyone does. I'm used to Nexus so I'm afraid of bricking the Note with dumb moves. That's why I am taking my time to read every important thread and asking here some doubts that went into my mind while doing the required reading. I have no warranty (no box nor invoice) so I can't afford to mess up with the new babe
Cheers!

this app will help you confirm your phone.
then you can proceed flashing twrp and supersu, things are so easy for N9005
and Welcome Aboard
Install phone info samsung from playstore. It could tell a lot about your phone.
To make it easy as long as the phone is running with android version 4.4.2 and above you should use twrp 4.4. If 4.3 use the right one for 4.3.

White Note3 do you have? There are several versions made by Samsung.
Regardless of the bootloader on the phone, I recommend using the latest TWRP as the latest TWRP can be used to flash all ROMs and zip files. Find your device from here: https://twrp.me/Devices/
Before moving to custom ROMs, I also recommend installing the latest bootlloader and ROM.
Not sure if your phone still has warranty but if it does, I would not change the ROM or root because doing either may trip the knox counter and void the warranty.

Thanks! I'm pretty sure it has 4.4.x or lollipop. Should I update to any of those versions (just in case it comes with 4.3) first and then install TWRP?

The phone doesn't come with box nor invoice so I don't have any warranty xd
What is the number or version of the latest bootloader?
What is the model # of the phone? There is the n-900t, n9005, n-900w8, etc.
N9005, it's the european unlocked version
The model # is important when asking questions because the AT&T version of the note 3 has a locked bootloader so it's more complicated to flash custom recovery and to get root.
If you want to run custom ROMs, I recommend upgrading to the latest modem and bootloader, install a custom recovery, back up your stock ROM, and try some custom ROMs to see which one you like.
Look for the tar version of TWRP for your phone from here: https://twrp.me/Devices/
You can flash TWRP with Odin.

I'll get the phone tomorrow!!!!!
So, by upgrading to the latest official rom avaiable I'll have the most recent modem and bootloader, right?
Do I need to follow the order you mentioned: modem->bootloader->recovery->backup->croms or can I flash TWRP, backup every partition, flash most recent modem and bootloader (not sure if I can flash a bootloader) and then install croms?
No, only flashing a newer custom ROM won't update your Bootloader and Modem. You will need to flash those files separately via Odin. Then you can flash the custom ROM you want. The order is simple. Get a custom recovery first, TWRP. Then update your Modem and Bootloader. Then wipe the device from TWRP (full wipe, take backup beforehand if you need) and flash the custom ROM of your choice.
Safest way to upgrade the modem and bootloader is via ota update on a completely stock unrooted rom with stock recovery. After the phone is running the latest rom, then start with customization.

I'm from Portugal but the phone is unlocked (no carrier) and they only have firmware for carrier notes... Which one should I download and flash?
Also... with a G2 I flashed a .kdz file (official rom) and ended up with a bricked phone (later fixed via warranty), but I have no warranty in this phone, how can I make sure that the file is safe?
Just check for software updates from your phone.

It says the phone is already at the latest version. I've cleaned framework services and checked again but got the same result.
Try removing the SIM card and moving the date ahead by two days, then try again.

Done that, no update avaiable. Connected to Kies3, no update avaiable.
Is it really in a old version? It's 5.0. Do I really need the latest version to start flashing a recovery?
Also, can I use the recovery without flashing it? I want to check if it works nicely before flashing if it is possible. TWRP can be used to flash any rom right? I'm interested in trying darklord first.
Yes, you can flash recovery without updating. I suggested updating because the update probably deals with the stage fright bug.

need some assistance with i337m and getting back to stock.

I have read a fair amount here, but I'm not getting entirely relevant info and am hoping for some help.
I THINK I have finally found the place for stock roms. sammobile.com???
Now a bit of background.
I bought this phone used a few days ago. When I had a look, it is already rooted, which I'm fine with.
It is running 4.4.2. I'd like to upgrade to 5.0.x. Gotta friend with the same model. That's what he recommends.
I can live with 4.4.2 if I have to, meaning if I can't upgrade.
Since this is new (to me) I can live with losing all user data. Only thing is my wifi password is long and random and a pain to type in, but that is about all I'll suffer.
I had removed some apps using debloater, mostly just to see, but have since restored them. Then tried to update, got the message, which essentially says "you've got a custom rom. No updates for you".
I know the phone is unlocked, but not sure if factory or by unlock code. Does it matter, and if so, how can I tell?
I know the previous owner had a fido sim, and I noticed some bell apps on here. If I've read correctly, that doesn't guarantee this was originally a bell phone. Is there any way I can tell? Right now I have no sim. I can shove in an old speakout sim that is deactivated.
So anyway

I've downloaded ODIN, but not a ROM yet, since I'm not positive who's I should use.
Also, I had gone thru the guide to enable AWS. That seems to work, as it would take the sim at the wind kiosk. I'd like to keep that, but if I have to redo it, that is fine.
I trust it is not a good idea to upgrade to a "stock" 5.0.x by just flashing roms?
Thx for any help.
ok, another question. I just registered at sammobile, but they don't seem to have roms for the S4??? Are they hidden somewhere? Where can I get stock roms, if not there? Thx
Nevermind. You have to type in the device name. It just isn't on the pulldown list.
Another question you might find stupid.
If I update to (for example) the Bell Roms, do I have to have a valid Bell sim in order to do an update?
Well maybe 2 stupid questions.
I still have to use triangle away for flashing back to 4.4.2 don't I? I read somewhere that they (meaning Samsung) expected the count to be > 0 at some point but I don't remember at what version, and I can't seem to find it again.
So what do you guys do? Flash it a couple of times to get the count right?
If the phone is sim unlocked, it should remain permanently unlocked regardless of whether you flash custom or stock ROMs.
The easiest way to get to stock LP would be to flash the stock LP rom via Odin from here: http://www.sammobile.com/firmwares/database/SGH-I337M/
Before the first boot with the LP ROM, the phon should be factoru reset via stock recovery.
Doesn't really matter whether you flash Bell, Rogers, or Telus. The hardware used by all 3 carriers is the same. The only difference would be in the apps that are installed with each stock ROM.

I think I have reflashed properly. I'm downloading the update (probably to 5.0.1??) via phone now, but I noticed after I started that I have the warning triangle. So maybe the update will not install when it is done. I'll know in a couple of hours I guess.
So I should have run triangle away BEFORE the reflash? Or are you no longer supposed to run that? Or is there some android version after which you are no longer supposed to use it?
Thx
Well, phone seems to have updated to 5.0.1, which is what I wanted. With the update, the warning triangle is gone also.
So thanks again for your help. I guess I'll be on to other things here.
