some people flashed this kernel on the i9200 model and it worked, you can flash the original kernel after that and you will still have root

I have the i9200 and confirm that this worked. I am now rooted. I have to admit it was scary taking the plunge. I just bought the device yesterday and was contemplating returning it. Did not want to brick my phone and have no recourse but it worked. I am now installing application on my device that require root and they are working.

Good to hear that it also works on the GT-I9200.
Do you use my kernel or did you go back to the stock kernel after rooting?

I kept your kernel. Is there any benefit in going back to the original kernel versus just keeping your kernel on the device?

I don't think so. As far as I know, the GT-I9205 kernel just has the additional LTE driver which is not used on the GT-I9200 device and should not cause any problems.

According to Phone Arena, the phone supports the following bands:

GSM:850, 900, 1800, 1900 MHz

UMTS:900, 2100 MHz

Note, the 1900 band is not under the UTMS, so I'm not sure if you will be able to get HSPA+ if you are in a t-mobile area that has been refarmed.

This is from Samsung's website under specs for the galaxy mega 6.3:

HSPA+ 21/5.76 850/900/1900/2100
EDGE/GPRS 850/900/1800/1900

I have the i9200 version of the phone and am using it on T-Mobile in NYC. I can confirm that I have gotten HSPA+ speeds as high as 12mbps download and 3.5mbps upload (although it's inconsistent - I think it has to do with the towers and the refarming of band 1900 - I also think we need someone to port an HSPA+ supported modem from a T-Mobile device over to this phone so we can have consistent speeds with signal stability).

Here is an example of the inconsistency: within a 15 mile drive my signal will fluctuate between HSPA+, Edge, G and, in certain spots, no cell or data signal at all. I'll get that full gamut of fluctuation all right within the 5 boroughs of NYC.

Just flash with PC Odin in download mode(VolDown+Home+Power).

Root working fine.

wp_status_check sector:0 ; wp_status_buffer:0x0000000aaaaa
wp_status_check sector:0 ; wp_status_buffer:0x0000000aaaaa

This is shown on all devices using this kernel. I have not noticed any adverse effect so far.

Can someone please post a stock kernel TAR for the 6.3 MAE firwware? I would like to try and flash back just the stock kernel and see if i can get screen mirroring to work again.
Samsung has this annoying habit to block screen mirroring from working when running a custom Kernel or a custom recovery.
