I have a Nokia 6300 4G with the following specs:
Model: TA-1287 DS
HMD Global Oy
KaiOS 2.5.4.1
Hardware version: qcom
Build number: 11.00.18.02

My goal with this phone is to uninstall some system apps, such as the browser. I tried the debug code, but it doesn´t work. I tried ##33284## and ##0574##. When I dial these codes the numbers disappear after I get to the # that follows the numbers. I purchased this phone in Paraguay so I was hoping that this debug feature would work. Since that didn´t work, I tried to make an edl cable to put it into edl mode. I didn´t have any success with that either. Can anybody give me a working debug option or a way to enter edl by shorting test points? Or maybe this phone is like the ones sold in the US that are almost impossible to work with.

I don't know anything about the particular phone, but in general KaiOS is harder to work with than standard Android. Do you know what network bands you need to get service? There might be other phones that are easier to lock down. Then again, don't let me discourage you from trying.

P.S. I think I know a James Auker from Paraguay. Email me edwin [at] plainemail.net and I'll be happy to show you some of the (non-public at the moment) android phone management stuff I'm developing.
