Hi
noob question, but I guess better safe than sorry
let's say I don't wanna root or modify my device, just want to flash genuine Samsung firmware with ODIN
how can I verify that the package is signed and doesn't include modified stuff that will trip Knox?
for example, I'm downloading firmware from here
http://stockroms.net/file/GalaxyS6/SM-G920F
if (by accident or not) someone uploaded modified package - it would trip knox
md5 check won't help in this case.
any other way to check if it's signed?
or will ODIN prompt me when trying to flash unsigned img?
tried searching for the answer first, but didn't find conclusive answer.
Thanks in advance

Hi,
I am using samsung galaxy S5 SM-G900R7, i am able to root this phone then started trying flashing of custom boot.img contating custom zImage. ODIN is showing successful flashing , but when i am restarting its always going in download mode with error message "couldn't do normal boot" . In download mode there is a line "QUALOCM SECUREBOOT : ENABLE". I doubt this is beacuse of locked bootloader.
I want to know is it really beacuse of locked bootloader?
I downloaded kernel for my phone model from samsung official website mentioned below and built in same way they have given instruction, so i ahve less doubt on custom zImage.

if yes then i have second question is it unlockable or not, i am not getting any unlocking method for samsung galaxy S5. whatever info i am getting regarding unlocking is upto galaxy S3 but not helpful for galaxy S5. PLease help me to come to a final conclusion on flashing custom zImage to phone.

As far as I'm aware most Samsung devices if not all have unlocked bootloaders, as for a soloution I haven't seen anything really but some say you need to re-flash stock then try from scrath or make a backup after reflashing stock and a custom recovery then format and restore to get it working.

Thanks a lot for your reply,
I searched regarding this and i found latest samsungs are coming with KNOX security in which SECUREBOOT is there, which doesn't allow phone to boot with any boot image if chacksum value doesn't match. so i feel even if bootloader is not locked here but same thng KNOX security is doing. Help me if you have any idea how to disable it in samsung galaxy S5. Getting way how to disable in previous series but not finding method how to do for galaxy S5.

Looks like getting rid of KNOX is a difficult task but not impossible: http://www.s4miniarchive.com/2013/12/how-to-remove-knox-bootloader-from-new.html

Hi,
Yesterday night you posted a link, that link was good but still my requirement is different.Yesterday i was not able to go through whole link you provided to me, today i was reading the whole article. its looks like they are trying to save warrany of phone even after flashing custom ROM. They are deleting bootloader contents of flashing ROM, even i will flash custom ROM with deleted bootloader contents, In phone bootloader will remain same with KNOX SECUREBOOT feature. My target is to flash with KNOX disabled bootloader so it will not stop booting with custom zImage.

Actaully that link was removing KNOX from firmware which you are going to flash not from phone if you have already KNOX is there. That is for if your mobile is not having KNOX and you dont want KNOX when you are going to flash with recent updated firmware so you can delete KNOX contents from firmware and can flash.

Hmm, it appears it not possible due to it having a locked bootloader/KNOX not being removable

I would pressume their will be some method of doing it and if it's not released yet it will be soon...
I guess it's just best to bide time and wait untill a concrete method has been developed
I have Sprint G925PVPU3BOI1 5.1.1 and was wondering what is the best/easiest way to root this phone. Does pingpong method actually work on this model? If not will other methods trip the knox thing and if it does will that only mean I won't get OTA updates or are there other disadvantages of tripping knox?
Thanks for the help

You can not root anymore with ping pong root. That only works on early firmware. Only disadvantages of tripping knox is that you won't be able to use Samsung pay if that matters, and it voids your Samsung warranty, meaning if something goes wrong Samsung won't touch it; however, your carrier will.
Thank you for the prompt information. With that being said is the process to root the model phone I have + 5.1.1 is to download odin put phone in d/l mode,use odin to flash with twrp and then flash rom, and then I can feel the joy or am I leaving out a step? is is correct where can I find the correct version of Odin and twrp, I've seen reference to it on this e but get a little confused about which file is correct for my model.
Thank you again for taking the time to help me

You must first root before you can install TWRP. There is a rooted kernel that you can use through Odin. Here is my thread with TWRP and the kernel.

Hello,
I have noob question. In order to keep knox 0x0 is it possible to download original firmware, unpack, delete unwanted apps and then rezip and flash over odin as original? I just want to debloat original ROM...
Right now I am using BK Package Disabler!
Cheers

Have you tried flashing the U firmware? It's the US unlocked variant and has zero carrier bloat. http://forum.xda-developers.com/att-galaxy-s7/how-to/xda-community-love-g930u-t3415875
To answer your question, no, you can't really modify the firmware. The way it's packaged up it's not like there's a file structure where you can delete a few APKs.
Thanks for explain. I am using international model GT930F.
If you're using F firmware -- that would mean you're on the Exynos CPU variant, right? If so, you have lots of options. Root, unlocked bootloader, etc.
Yes but right now I am trying to keep know 0x0 due warranty issue.

Is it for warranty purposes? What version android are you on at the moment, I've never tried it myself but in theory it should work, as long as as the bootloader is included in the flashing process.
6.0.1 With August Security Patch
Two Days pack I've repaired my phone usin repair Firmware and noticed that it flases a PIT also...that's why my question came up
My Knox status is 1... i had root earlier, so i dont know about tripping KNOX by this flash procedure

As soon as you root, you trip knox which is not reversible. Pit files tell odin what files to flash to which partition on the phone, using an incorrect pit file can cause a failed flash and damage to the phone. What you can do is download. I've never downgraded so don't want to advise you incorrectly. Hopefully someone who has will comment. Or try a search in the forum
In Sammobile site i'm unable to find (According to SamFirm Downloader requirements) the "phone" version code for first ever 5.0.1 (SEB) (SM-G920F)
There is an CSC and PDA, but no third firmware code...
Any suggestions?
I know everyone knows about it, but we nees to figure out how to bypass it. I tried flashing it and it never worked. I also tries using Odin and the firmware file was not the coreect file. I just need some support to find out the answer.
