it took you guys this long to find it?
You guys already had your code that was a code for another Samsung phone. You guys didn't have to find your code, it was practically handed to you... We were the first with the code *#3818790*# . We tried digging through our phone's firmware to find it, had no luck, but found it through a hex editor. That took a lot of digging, through 20-70mb firmware files, or basically, well over 1000 pages of text.
BTW, since we can reflash our phone's firmware, we are going really deep into testing already, with only 24 hours or so of the code being found. Many are being risky and bricking their phones to learn what certain items do. We can reflash our phones, so bricking is a non-issue with us.
The internals menu of the Eternity/Impression is very similar to the Behold's. Any useful hacks we find in the menu will probably benefit the Beholders as well. In the following weeks/months, I will try to post updates on here, or you can just watch the Eternity forum. Talk of a custom firmware is actually underway, and gaining ground with this new development.
