[Q] Knox and Custom Roms - Galaxy S 4 Q&A, Help & Troubleshooting

Hi Folks,
Apologies if this is the wrong place to ask...
I would like to Custom ROM my S4 and have been reading through this thread http://forum.xda-developers.com/showthread.php?t=2447832 about Knox. It would appear Knox hasn't been activated on my phone yet as there's no mention of it in Download mode, here are the details gained from Settings and Download mode:
Android 4.2.2
Baseband: I9505XXUBMF8
Build: JDQ39.I9505XXUBMF8
SELinux: Permissive
Secure Boot Status: Type: Samsung
Device Status: Custom
Odin Mode:
Product Name: GT-I9505
Current Binary: Samsung Official
System Status: Official
CSB-CONFIG-LSB: 0x30
Write Protection: Enable
I am rooted but have used TriangleAway to set status back to official without any problems, my question is am I safe to install Custom ROMS/Kernels without triggering Knox warranty void? If so and I wanted to install a modded Samsung ROM will this still be safe or will it trip Knox?
Thanks for any suggestions, I'm never normally this cautios about flashing, but I really don't want to screw up my warranty.
Many thanks,
R.

If theres nothing about knox warranty 0/0 in download then u are on old bootloader and safe. Dont know about the custom roms I guess stay away from any mh8 mh5 mgg fw. Im pretty sure they are they fw with new bootloader. But just keep searching round.

I've just bought a new S4 and it will arrive to my home in this week.... I hope it will arrive without Knox feature so I'd like to understand too what to do and what to not do in order to prevent Knox problems.
I think I'll flash the Google Edition ROM... any suggestions?

Thanks Buddy

Just bought my S4 (I9505)

Hi guys!
Yesterday I've received my new S4 and obviously I'm really happy!
I'm planning to root my S4 after some tests (just to be sure the device has not problems) and I'm thinking to flash the Google Edition ROM.
Now some questions:
- Is there some test,stuffs to check or common warrenty problem to check/wait before root my S4?
- Just rooting the device will invalidate the KNOX? Is there a way to restore the KNOX or may I root my device only when I'm sure I really want invalidate my warrenty?
- After rooting decision/time... I live in Italy but I've bought an EU S4: do you suggest me to change the CSC (I9505OXXBMG3) to ITV and flash Italy sotck/mod ROM or it doesn't matter and I can stay on the actual CSC?
- In your opinion, Is it really worth to flash the Google Edition 4.3 or may I wait for the official 4.3 from Samsung (I saw the leaked ROM so maybe it's time for official!)
Thanks guys!
If your device has the older bootloader you're fine for flashing as it doesn't have KNOX implemented. If it has the new bootloader with KNOX, flashing a custom rom will void your warranty forever. It flags it in download mode and you can't remove it even if you went back to fully stock, so you still wouldn't have any warranty

Incase the above method failed, then i am sad to tell you that there is a long process that is probably going take more than an hour to complete the downgrade process.
First of all, remember that when you upgraded to 4.3, you also upgraded stuff like BL(bootloader), AP(formerly known as pda which can be downloaded from this site), CP (modem of the phone) and finally CSC. So, the trick is to download the BL of 4.2.2, AP(PDA) of your region, CP of your region or your carrier, and the CSC of your region. Trust me, finding these stuff can be hard depending on the popularity of your region and the popularity of your carrier.
Hopefully, you were able to download all the above mentioned stuff. Now go ahead and flash these things with odin. Also note that wiping the device with the stock recovery ( vol up + home Key + Power button) might be necessary. While flashing with odin, DO NOT CHECK ANYTHING APART FROM AUTO REBOOT AND F. RESET TIME.
OR THE EASIEST IS PROBABLY TO WAIT FOR THE OFFICIAL RELEASE AND THEN FLASH IT WITH ODIN. YOU CAN DOWNLOAD THE OFFICIAL RELEASE WHEN IT IS AVAILABLE IN THIS WEBSITE ANYWAYS
will this work?? splitting the firmware? anyone?

Thanks for response!
I've just reboot in download mode and my S4 printout:
ODIN MODE
PRODUCT NAME: gt-I9505
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Offical
CSB-CONFIG-LSB: 0x30
WRITE PROTECTED: Enabled
Have I the older bootloader? I can't see any knox strings...
If yes, that means that if I want to flash the 4.3 Google Edition ROM it's better to flash it now before Samsung send me the OTA update of the official 4.3 ROM or I didn't understand well?
In which ROMs Samsung has introduces the KNOX.... I'm little bit confused because someone of you has KNOX but my S4 says to me via OTA thet there is no new update...

Unable to Root Note 3 900W8

Hey guys
I have a Canadian Note 3 model 900W8
Yesterday I had to flash back to the stock firmware due to a bootloop issue I had...
Today I tried to re-root my Note 3...and when I press start in Odin, it fails.
I'm doing the exact same method I did the first time I rooted it, and it fails. In dowlnoad mode, the tiniest bit of progress is made and it just stops.
I believe it says recovery failed in download mode.
I've tried to do this on two different computers using various USB ports.
I have developer mode enabled, and usb debugger is also enabled.
Anyone have any ideas?
Thanks
Were you able to root using the same setup before?

What firmware are you on 4.3 or 4.4?
Sent from my SM-N900W8 using xda app-developers app
I'm currently on 4.3
and yes it worked the exact same way last time...I'm not sure what I'm doing wrong this time...
I'm not able to post the url to the site that I used last time to root my phone....maybe if I space it out lol
www . android . gs / root-install-twrp-recovery-canada-galaxy-note-3-n900w8/
but yeah it worked perfectly fine when I did it last month
Try using cf auto root which you can find in the original android Dev section ( make sure you download the one for 4.3 ). If you're not successful in using Twrp, try Cwm as custom recovery ( although I'm using Twrp on 4.4 right now ).
alright so I tried again
in ODIN mode this is what I see
ODIN MODE
PRODUCT NAME: SM-N900W8
CURRENT BINARY: SAMSUNG OFFICIAL
SYSTEM STATUS: OFFICIAL
REACTIVATION LOCK: ON
KNOX KERNEL LOCK: 0X0
KNOX WARRANTY VOID: 0X1
QUALCOMM SECUREBOOT: ENABLE (CSB)
AP SWERV: S2, T2, R2, A2, P2
WRITE PROTECTION: ENABLE
and this appears after the flash fails
SECURE CHECK FAIL: recovery

Ouch, you tripped your KNOX. Okay no worries. You're currently on 4.3 bootloader, and if you're trying to flash the 4.4.2 firmware - http://forum.xda-developers.com/showthread.php?t=2614772
I suggest you do that first.
Yeah I rooted my phone a month ago and tripped knox
I'm not upset about it or anything...
Thanks for the help, I'll give what you suggested a shot right now and will reply with the results

You have to turn off reactivation lock then flash again. It can be found in the security settings.

I have to turn off reactivation lock and flash again?
I already did step 1 of what nicholaschum suggested I do, and I have 4.4.2 installed now.
Before going through the setup process of setting up my phone, I went to root it immediately, but I got hte same failure I've been getting...
I assumed it's because I have to enable USB debugging...so I setup my phone...has me enter my login/password for my phone becuase of reactivation lock...confirm 4.4.2 is installed....enable dev mode.....check usb debugging....
So before I do anything further I just want to get confirmation....after checking reactivation lock in security settings (for some reason it wasn't checked just now when I looked even though I had to login with the info when I first booted the phone after flashing to 4.4.2)
do I flash 4.4.2 again and continue with what nicholaschum said to do?

You can continue what you are doing just make sure it says off when you are in download mode.

I think as long as reactivation lock is on in download mode you won't get root or flash custom recovery.
Hey guys
I now have a rooted Note 3 running Kitkat 4.4.2
Huge thank you to you both of you who helped me this evening.
Now my biggest problem is trying to figure out what rom I want to install.
What would you guys recommend? The only ones I know are Jedi......xnote and wicked.
Basically don't want an bloatware that comes stock with Samsung devices lol
I personally use vision x n3 from the tmobile section as it comes stock and just add my own customization courtesy of xposed installer. Having said that, each of us has their own preferences so read the features that appeal to you and take that rim for a spin. Some roms though need a fix for bt, wifi and nfc along with a kernel that supports them in order to function especially those based on n9005.

So the roms that are compatible for our N900W8 are for the n9005?

I think every rom made for a note 3 snapdragon ( N9005, N900T, N900A, etc..) will work on our N900W8 except as i mentioned, the wifi,bt and nfc which will need a fix. I found that only AT&T and Tmobile roms don't need a fix for wifi,bt and nfc, They work right off the bat. Problem is there's not many 4.4 based rom from them because of their locked bootloader. If you're still looking for a good rom to try, give Knoxraid 3.5 a spin.

Updating Baseband & Firmware to fix issue with CM11

Hi,
There was another post on this but unfortnately they poster did not actually describe what they were doing to fix it, so I am here to try to get help. (link to their post is here)
I am having a dropped call issue (and a camera issue) that I heard might be fixed by updating both the baseband/modem AND that firmware.
So here we go.
When I boot into download mode:
Code:
ODIN MODE
PRODUCT NAME : GT-I9505
CURRENT BINARY: CUSTOM
SYSTEM STATUS: CUSTOM
KNOX KERNEL LOCK: 0x0
KNOX WARRANTY VOID: 0x1
CSB-CONFIG-LSB: 0x30
WRITE PROTECTION: ENABLE
I am completely overwhelmed with what firmware/modem I want to acquire. I live in Norway, and travel to the US a lot. So whatever would be good for that.
Will any of these updates require me to re-root? What is this wifi-fix, do I need to get something like that as well? Is the KNOX warranty 0x1 fixable? Should I flash anything else besides baseband & Firmware? What is bootloader? CSC? PDA?
Thanks for taking some time.
For camera
My DropBox Link
Install this an tap in once..then try opening the camera.
For dropped call issue..

[Q] About kernel and ChainFire auto root

Hello
i have the SM-N910C running the official lollipop firmware,
days ago i've rooted it using CF auto root through the odin,
And it was successful, but the question is the CF auto root
replacing the stock Kernel to another one while flashing ?
cause when i reset flash counter using triangle away even without restarting the phone it still shows in triangle away:
counter: 1
Binary: custom
system: official
but in bootloader it says:
current binary: samsung official
system status: official
secure download : enabled
knox warranty void: 1
rp swrev: 1
and the reactivation lock is off in the settings and the bootloader
i just need the software updates after root
and resetting the flash counter to Zero
and to know the kernel is it stock or custom
anyone could help ?
and sorry for any bad english, thanks.

Hi, cf autoroot doesnt replace your kernel, so u should still have stock kernel.
and also as far as i know, triangle away doesnt work on note 4 ... so right now there is no way to reset the counter to zero.
and 1 more thing is you may have posted this question in the wrong thread, you should have posted it in the Q&A thread. ^^

Good luck trying to figure out how to reset that counter permanently - so far no one managed to find a way to do that since the introduction of KNOX back in 2013.
