Default [Q] Upgrading/Downgrading Unlocked MAXX

Just unlocked the bootloader on my MAXX and installed TWRP/Root. I haven't tried upgrading or downgrading versions yet. I'm hoping someone can give me some insight to doing this.

My MAXX is still on 4.2.2(Jellybean) cause I didn't want to risk losing root when my bootloader was locked. Now that that's a non-issue can someone answer these question?

1) Since I'm still on 4.2.2 can I take the 4.4 OTA update even with TWRP installed?

2) If I can't take the update, then I would have to RSD up to 4.4?

3) Once on 4.4 can I go back to 4.2.2 (jellybean)? Seems I've read you can but you can't downgrade the bootloader or a bin file?

I've read differing opinions when it come to this and would like to try 4.4, even though it sounds pretty buggy (email active display, home button double, battery life, etc.) but I'd like to be able to go back if I didn't like it. I've seen a lot of people regretting that they went to KitKat because of these issues.

Thanks,

Mike

1) no, you need to be completely stock with stock recovery

2) RSD is an option

3) you can "downgrade" from 4.4 to 4.2.2 by flashing all the files except the motoboot.img and the gpt.bin. just don't downgrade to the pre-camera update (12.7.7) and then take an OTA because you will hard brick

I also had a similar question. I unlocked the bootloader and am on 4.4 stock rom. If i want to relock the bootloader and return to stock 4.4 without root can i just rsd lite using the 4.4 fxz? Hoping that brings the recovery to stock as well, in case there are future otas

Yes, a full fxz will restore the stock recovery and unroot you. You can relock just not sure why you would want to plus it will always show that the device as status code 2 which means it has been unlocked at some point

Can we run the 4.4.2 firmware (Topsnakes ported from X) on our maxx with 4.2.2 gpt and bootloader and motoboot? I know we can go backwards but not sure if you can go newer software and older boot and so forth.

Thanks

Was also wondering if we were to load the 4.4.2 ported from the Moto X if we can roll back to 4.2.2 12.15.15 if we just don't try to load the motoboot.bin and the gpt.bin.
