[Galaxy S 4 Mini Q&A, Help & Troubleshooting] hobbya:
I tried to replace the CSC of my i9192 with a i9190 but failed. I extracted the cache.img.ext4 and hidden.img.ext4 from the i9190 stock rom and combined them into a single csc.tar file. I did not create md5 and flashed the csc.tar but odin reported an error of invalid int4 img.

Could you advise if I have done anything wrong? And can I just flash the cache and ignore hidden? I was told that cache contains the information related to the operators and hidden contains bloatwares. Thank you.
[Galaxy S 4 Mini Q&A, Help & Troubleshooting] SilviuMik:
Extract the cache.img.ext4 from any stock I9190 or I9195 rom. DO NOT try to modify cache at all it will fail ! :)

Then place it back in an arhive simple as that :P

tar -H ustar -c cache.img.ext4 > cache.tar

md5sum -t cache.tar >> cache.tar

mv cache.tar cache.tar.md5

Flash it with Odin 3.07/3.09 as CSC

Thanks for your guidelines. However the same error still happened. I tried again by flashing the original i9192 csc and it was successful. So this means the procedure is correct but for some reason the i9190 csc is not accepted. Appreciate if you can advise other thoughts.

Noticed my Baseband don't get updated and my phone is vodafone locked, but the rom i'm using to do this is I9195XXUBMJ7_I9195VFGBMK1_TCL wich is the latest vodofone pt. Is this a protection because its a network locked phone?

Is there any way to update the baseband on a locked phone? I don't want to unlock just to update to another more recent locked baseband.

Thank you.
[Galaxy S 4 Mini Q&A, Help & Troubleshooting] mfPPC:
Don't know if this is 100% correct but I think the problem is when the "Current Binary" and "System Status" is "Custom" my phone don't update the baseband!

I managed to update it only after a full reset of the phone and re-upload of the original rom with the "F. Reset Time" checked on Odin in order to get the "Current Binary" and "System Status" with original samsung. After that uploaded the rom with the deleted knox bootloader and everything updated correctly including the baseband.

Now everything is working with the the latest vodafone pt firmware and without knox!! :laugh:

Silviu, hi..

Any ideas on how we can install CWM in a pre-rooted rom?

A quick walk-through, maybe? :fingers-crossed:
[Galaxy S 4 Mini Q&A, Help & Troubleshooting] SilviuMik:
U mean how to "make" an rom and include CWM before u flash it on your phone ?

If so just download your rom, extract it and replace recovery.img with the one u extract from recovery-clockwork-6.0.4.4-serranodsub.tar.zip

Then repack the rom like in OP and flash it on your phone.

Never done this but i think it should work :)
[Galaxy S 4 Mini Q&A, Help & Troubleshooting] dreamdrake:
Hmmmm, yes..Should work..Will try and let you know..Thank you!
[Galaxy S 4 Mini Q&A, Help & Troubleshooting] dreamdrake:
Not working.. :(

While everything installs great, in the end of the installation CWM pops up asking "should I install untrusted package"?

No name of package, nothing..If I say yes, it says installation failed and I get the basic options of CWM. ( reboot system now, etc..)

It boots into the system, everything ok..When i try to restore my Kies back up, Kies does not recognise the phone and says it is not supported.

I tried including a CSC of I9192 just in case but still the same.

I think it is something with the CWM version. Could it be needing a newer version?

Food for thought.. :)
[Galaxy S 4 Mini Q&A, Help & Troubleshooting] dreamdrake:
Worked finally! It was probably something I was doing wrong while adding CWM to the rom.

I flashed a factory rom first (just to be on the safe side), and then flashed the new one over that.

I used Silviu 's I9192XXUBML4_I9195OXXBML1_I9192XXUBML4, and after installed, I flashed arco's 6.0.4.4 CWM.

Everything is working as should.. :D (Very Happy) :D

Do you think it would be possible to remove the KNOX Bootloader from my galaxy s4 with mk2 4.3 by using an app like Terminal on the phone by deleting the KNOX files and then flashing a the 4.3 firmware that doesn't have the KNOX bootloader files in it? Or anything like that?
[Galaxy S 4 Mini Q&A, Help & Troubleshooting] fernandovg:
have anyone tried with 4.4.2 I9505XXUFNA5 for Galaxy S4 I9505?

Do I need to unroot my 4.2.2 to flash the ROM (after deleting knox files) to avoid Knox 0x01 ?

OR I keep my root and follow this guide to keep my knox 0x00?
[Galaxy S 4 Mini Q&A, Help & Troubleshooting] dreamdrake:
If you already have a Knox bootloader, then you're stuck with it for good.

If you don't,

only then

you can delete the Knox bootloader from the 4.3 firmware and flash it.

But, I would suggest you ask at the S4 threads, as the boot loader removal in these roms might need extra or different steps.

How to do this on OS X?

Hi [MENTION=4344511]SilviuMik[/MENTION]

Can you acknowledge us about how it's done on Apple's OS X platform?

Simply deleting;

aboot.mbn

sbl1.mbn

sbl2.mbn

sbl3.mbn

files and flashing the rest via Heimdall GUI on OS X does the same? For example, I returned to previous (non-knoxed) stock Samsung firmware like that guy did in this video:

If the wget command worked for the sammobile firmwares we could write a bash script for all of this,automating it from making it KNOX free to getting it pre-rooted :D maybe also deodexing the firmware so themers could come in and help clean the ugly touchwizz.

btw, one of these commands damaged my internal memory the last time I did it. I couldnt install any apps. I dint delete it from terminal but I deleted them from root explorer manually.

After purchase, I almost instantly flashed CM-based rom on it, and never updated to any Samsung rom. So I was thinking that maybe the hidden partition was introduced/modified by size after I bought my Galaxy (Sept 2013) and that's why it doesn't fit on the phone. But that would be unusual.
