You'll have to flash an older kernel, to get the service mode. Search the forum.

See the post above yours. Search the forum for how to flash an older kernel, get to the Service Mode and then flash the 4.4.4 kernel back.

Hello. Thanks for the guide OP. Been trying to unlock a T-Mobile S4 for a friend. The phone was on 4.4.4 and has Knox. I've Odin the amdl modem and it's visible in settings, about but no matter what I do his phone won't bring up the service menu. I even Odin his phone completely back to AMDL, MK2, I've tried them all and never get a service menu to pop up when I enter the code. Is his phone unable to be unlocked because of his initial upgrade to 4.4.4 or are there other steps I can take to get that menu to show? Thank you

heres a method that i noticed didnt get mentioned much in the forums. I have a Tmobile SGH-M919 on 4.4.2 downgraded from 4.4.4.
Step 1: *#0011# takes u to service Mode screen Step 2: Tap "menu" button, then select "Back" Step 3: Tap "menu" again, then select "Key Input" and type in a Capitol "Q" letter. Step 4: Tap "menu" again, select "Key Input" again and type in "0000".....be patient and wait for like 5-8 seconds and the Hidden "Service Menu" should magically appear. Then from there u can follow OPs original steps in his thread.

Hello all,

Not trolling (most posts that start this way usually are aren't they?.. )

So (ignorantly),

A lot of work is required to 'not trip knox' and get functionality of newer modems and keeping older boot loaders.

What is really the 'impact' on either the end user or organization that has 'knox tripped' devices?

I will be joining the M919 community coming from an i9505G and have decided that 'saving knox' really is not that big of a deal.

As I see no benefit to knox; I see no interest in working at not tripping it..

I can not find anything where people are saying ".. you have that problem because you tripped knox. "

I see more people saying ".. my phone will not charge when powered off." And the response being ".. you are on the old bootloader."

Similar things around the modem..

I have read that knox is about encrypting the device and assuring that the device is 'stock' and can be trusted.. (not unlike joining a windows machine to a domain or AD)

The M919 that I will be acquiring has already been sim unlocked; does that mean knox is already tripped?

Thank you for taking the time to read this..

This is not the proper thread, but to answer your questions

The only real impact is that you may not be able to do a warranty claim with Samsung and not be able to use knox services.

Because having a tripped device has no effect on performance or usability, this is not the purpose of knox. Updating bootloader does solve many issues

No necessarily
