Modded demo ROM for LeapFrog Epic (MT8127)

...or as what I call it, KermitMod. :P

My previous post about the Epic was quite a mouthful, but here's a link to the edited ROM for ex-demo units to be converted to retail. I basically had to edit the demo firmware to work around the issue of the bootloader being locked, preventing ROM backups from other Epics to be flashed through normal means.!cuhHFYTC!GC6wU1MxDybNX_tU50aMpHbFnb3TjAh5dVaWn_cNj8Y

As what I wrote earlier, this ROM has to be flashed using a feature tucked away in SP Flash Tool, i.e. Write Memory. You can't flash this as you would with any MediaTek device, as it would give out an authentication error. A bonus feature I added for this is support for Google Play services, allowing owners of ex-demo units to download content off Google Play Store like YouTube Kids and whatnot.

Let me know if you run into problems with this ROM - I know, the instructions I wrote were a little unclear, but I'll get into that as soon as I can. ;)


May I interest you in yet another LeapFrog Epic post? :P

I've been getting a lot of inquiries lately from parents asking how does one convert a store demo unit to a retail one. Apparently a number of Epics, mine included, were sold on eBay, Craigslist and other classifieds, are programmed with a demo ROM meant for displays on Toys R Us, Best Buy, Fry's or whatever outlet these things are sold.
The real caveat here is this: the boot loader is locked, making straightforward ROM flashing mostly impossible (hence why I wrote an open letter to LF asking if they can provide an unlocked bootloader). Now before you lose hope and say "Oh this is a waste of $50! Why did I even buy this crappy toy?", there is actually a way around this and as what some of those who inquired me can attest, it works well unimpaired.
To back up the old ROM and flash the newly-modified system.img back to the device, you'll need to download SP Flash Tool and the stock firmware image (said image can be found on this post). Load up the original retail …
