gbenga, you've got the distinction of having encountered a unique and previously unknown error code. Well, one known and one unknown, actually.
The code you have is actually two codes, because there are two bits set. In hexadecimal, a 6 is made up of two different bits, a 4 and a 2. So your codes are individually 0x200000 and 0x400000. The 0x400000 is a code we know already; here's the information about it from the [[iPhone Kernel Panics#Section_SEP_ROM_Boot_Panic|iPhone Kernel Panics|new_window=true]] wiki page.
* 0x400000 - is the Wireless Charging Flex (Back Glass).
Unfortunately, we haven't encountered the other code, 0x200000, previously so at this point we have no idea what it means or how to help you with it.
The only other time we've run into the charging flex issue was here.

In that case, apparently just the act of removing the rear cover and refitting it resolved the problem, but I'm afraid that's probably too much to hope for in your case, but worth a try.
