I finally found a method to unlock the secure boot on these TINNO flip phones.
I used the BKerler EDL tool available in the ReLiveDVD.
First thing I did: TAKE A BACKUP OF THE WHOLE NAND! (edl rl -whateveryouwantfolder-)
Second thing I did: flash this firmware ([Login to see the link]) which is a debugging firmware. It has ADB and fastboot access.
Command: (/opt/edl/edl qfil rawprogram_unsparse.xml patch0.xml ./) - I was reading the files off of a folder within my Windows 10 partition.
Third thing I did, was enable OEM unlock using the same tool (./edl modules oemunlock enable)
After that, I powered the phone up into recovery (hold Vol Up, and boot into the Bootloader.)
Then I ran "fastboot oem unlock-go" which unlocked the boot loader.
From there, I could then boot into OS and manipulate the system partition using adb as root (adb root && adb shell)
I was able to replace the Google Apps with some homebrew (I kept the browser, I don't go full kosher, my needs are different.)
Anyone wanna try and report back? I was even able to enable Mobile Hotspot and USB tethering by modifying the JSON files in system/b2g.
