[Guide]Modify stock rom and delete bootloader with Knox for Galaxy S4 Mini

[essasmj]

Finally I succeeded

After many trials the wifi, sound and SIM worked

I used tz.mbn from the old version 4.2.2 and NON-HLOS from 4.4.2

and I kept trying and one time it succeeded

the update is not working but this is good for me since I am not planning to upgrade to 4.4.2

good luck

My IMEI says null / null and Baseband is unknown. Wifi, sound is not working Going to try your NON-HLOS method now.

Edit: flashing the NON-HLOS from 4.4.2 restored my IMEI and baseband in JB. Got back sound and IMEI. Wifi is still not working.

Edit 2: Wifi is now working. I flashed tz.mbn of Kitkat 4.4.2 and then rooted the device with CWM. i.e S4Mini_RootKit_v2.zip(for busybox) and UPDATE-SuperSU-v2.01.zip( for latest version of SuperSU). After reboot, I opened SuperSU and it asked if I wanted to disable KNOX popups and KNOX. I pressed yes. Then I went and turned on Wifi. Its working. Successfully downgraded to a fully functional 4.2.2 with tripped kitkat bootloader.

Here are the files to fix IMEI, Baseband, Wifi ( Root the device and disable KNOX from SuperSU app after flashing). Extract rar files and flash these one by one.

@SilviuMik:

sorry, i have two little questions for you
I read that with F4k's test kernel now wifi works also with knox-free bootloader but kernel doesn't fix the FC under secury settings.
Do you have find a way to fix it?
Last question: under your KK firmware you are using old tz.mbn from JB or the new KK one?

Thanks in advance

All new from KitKat . At me i don`t have any force close on settings

 

[s.goten]

All new from KitKat . At me i don`t have any force close on settings

OK. thanks
but you still have old knox-free bootloader?
have you first flashed stock KK (without knox files) rom from Odin and then flashed f4k's kernel?

No mate.
I compiled my own kernel ( F4k removed knox mentions from source / defconfig ) , removed all with knox & co from ramdisk, removed knox apps , containers from system , removed knox from build.prop , removed bootloader ( aboot sbl 1 2 3 ) and it works with all new modem / tz / rpm etc
Is not so easy to remove knox now as it was on JB . If u don`t remove ALL, even one line / app left u get random reboots
If u delete too much u get unstable system ... or no wifi / such

ok. thank you very much for answer. now it's very clear :good:
unfortunately I'm not so expert about kernel compiling. can you or anyone do same work for i9195 or post a guide with steps needed and files/apps to delete?

if not possibile thanks anyway.

 

[rrgrrg]

so i was able to fix the kitkat settings fc by packing hidden\tz\rpm\cache\hidden\non-hlos images in a tar.md5 and flashed it after i used the kitkat (flashed by cwm) and everything is sorted out

Wondering if the way you did this and got a KNOX free 4.4.2 bootloader would work on my phone? I have a GS4 lte from t-mobile. The method shown in this forum worked to get me 4.3 KNOX free bootloader. :good:

No clue
U can check my github sources and do the same with your kernel . U need to learn a bit how to modify kernels / compile etc

Could you tell me what computer OS you are using, and what programs you are. Again thank you for you help.

LinuxMint 17.1 Cinnamon x64 in a Virtual machine hosted by vmware Workstation 11.
Kernel compilers Linaro GCC 4.7.4-2014.06 Toolchain ( a good starting point )
http://forum.xda-developers.com/showthread.php?t=2098133
Linaro GCC 4.9.3-2015.01 Toolchain after a while, but u need to modify your source code and fix compilation errors caused by newer toolchain ( harder )
Rest, u should google a little how to compile a kernel, how to modify a kernel etc

Your current rom does have Knox included . U can`t delete it or so, u can only hide it with Indian bootloader from kitkat. If u have root u can try to flash new rom ( kitkat ) with FlashFire
That should "in theory" allow u to flash a stock rom, don`t trigger knox, keep root and have an option to go back to 4.2.2 if needed. I did not try it, only what i read

 

[subodhdhull]

i unpacked the 4.4.2 rom and modified it according to my requirements. when i tried to create system.img.ext4, i got bad sector error on tune2fs - c0 - i0 system.img . what should i do?? any suggestions plz??
