LeapPad Academy (second-generation, RK3326) stock ROM

Mon, 29 Apr 2024 01:30:00 +0000

After a month or so of waiting and prodding around, I've managed to dump the stock firmware off the Rockchip revision LeapPad Academy, version EPIC4.user.1.7.2109.312280833:
https://archive.org/details/leapfrog-epicv4-firmware
https://drive.google.com/file/d/13TB0eCU...xQ2XI/view

The firmware can be flashed using RKDevTool 2.69 and later. I did test the system (super), boot and recovery partitions and they do seem to work fine, but don't blame me if anything happens to your device.

I have also included two uboot images in the package: the stock factory uboot based on the latest available OTA update, and a hacked one with the anti-dump code patched out. Make sure to flash back to stock uboot in case LeapFrog issues a new OTA update! Mad props to pseudolobster and RedScorpioXDA for the uboot hack discovery and imgRePackerRK, respectively, without which would make this effort impossible.

LeapPad Academy ROM v1.1.171 (KOT49H.user.1.1.171.20190530.155308)

Wed, 27 May 2020 02:59:17 +0000

Special thanks to Roy Boxer for supplying me with this one:

ROM build number is KOT49H.user.1.1.171.20190530.155308. Should work on all editions using SP Flash Tool v5.1744 and later. Just make sure to BACK UP the stock ROM first before flashing this, and clear /data and /cache via recovery mode after flashing. Trust me, I bricked one of my Epic demo units before and it helps to keep the stock secro, seccfg and NVRAM prior to doing anything with the Epic.

P.S.: If you're getting a signature error upon flashing, try unticking SEC_RO and then try again.

Leapfrog Epic stuck in logo loop

Wed, 07 Nov 2018 13:40:34 +0000

Hi,

I tried to install TWRP and everything seemed to go ok.

However now the epic wont boot and loops the leapfrog logo.

Is there a way I can recover?

Many thanks

The Epic was on KOT49H.user.1.1.95.20171215.140555 updated through normal system update.

I noticed in the post:

I'd also like to add that if you ended up with a boot logo loop (i.e. the LeapFrog logo itself, not the animated loading screen), try flashing the Academy Edition ROM first.

Is there a tutorial on how to do that?

I have also worked out that the epic will boot into TWRP and Epic ROM on first boot. But it is any reboot after that where the loop takes place.

Seems to be working fine now. I re-installed recovery through SP Flash. Booted into TWRP on first boot and enabled modify.

This seems to have fixed the issue.

Install TWRP, Google Play and SuperSU root on your LeapFrog Epic

TWRP 3.0.2-0 recovery for LeapFrog Epic

Thu, 05 Apr 2018 03:13:00 +0000

Unofficial TWRP 3.0.2-0 for Academy Edition
Can be flashed through SP Flash Tool v5.1744 or later using the stock 1.1.95 ROM. Usual precautions of course.
Basic functionality works, e.g. backup, ZIP flash, ADB/MTP and so on. This is by and large a better alternative than using Kingoroot or any of those shady root utilities, not to mention it allows users especially parents to back up stuff from their kids' Epics prior to a factory reset or some other repair job.

Epic Academy Edition ROM (KOT49H.user.1.1.95.20171215.140555)

Wed, 14 Feb 2018 12:48:33 +0000

EDIT: Replaced download link with a fixed version as the previous one had a seemingly-intact yet broken boot.img that works fine at first glance, but would cause an error message if you attempt to perform an OTA update.

Here's a working dump taken off my personal unit which received the December 15 update.

Pollywog utility for Epic

Sun, 09 Jul 2017 03:03:23 +0000

Was a tad bored lately so I did this:
https://github.com/huckleberrypie/pollywog

Quote:Pollywog - The LeapFrog Epic Toolbox

Just a minimal utilities menu for LeapFrog Epic, the purpose being to unlock a number of hidden yet useful options that were present in vanilla AOSP but disabled for some reason by LeapFrog. Think of it as like a watered down ROM Toolbox of sorts, but tailor-made for LeapFrog's Android tablet. I came up with this as switching to another hotspot is a bit of a chore, so yeah. I know it's simple and all, and my Java skills leave a lot to be desired, but I hope this would be of some use to you guys.
Features

Shortcuts to commonly-used and some advanced Android features (WLAN and previously hidden stuff like the MTK engineer menu, lockscreens and developer options)

A link to the LeapFrog support page

And many more being planned

Planned stuff
A root exploit perhaps?

Cache cleaner

A terminal emulator

Enhancements to the parental controls/restrictions feature (considering how these can be bypassed somewhat )

LeapFrog Epic root and Play Store

Sat, 13 May 2017 01:00:32 +0000

DISCLAIMER: I am NOT in any way responsible for any data loss or hardware damage caused by unsupported software on your LeapFrog Epic. Always observe common sense and make backups before doing anything drastic, OK?

A number of people, parents to be specific, have been asking as to how can they install Google Play Services on their children's LeapFrogs. Unfortunately, this involves rooting the device, mostly using utilities such as Kingoroot. In my case, only the PC version of Kingoroot works; Kingroot may also work, but the default Kids Launcher spazzes out for some reason, making it unusable.

Prior to rooting, you need to install the necessary ADB drivers (I think Windows 10 will have that installed automatically), then enable USB debugging using the Developer Options shortcut in Pollywog or some other developer options shortcut app (tapping the Build Number item in About device does nothing, unfortunately).

After that, install Kingoroot on your PC, then follow the on-screen instructions. Once you get your Epic rooted, follow the instructions in the guide here to replace the Superuser app with SuperSU: https://forum.xda-developers.com/android...y-t3573361

You may want to mount /system as read-write as this involves copy/pasting files to /system. This tool should come in handy in that case.

Now on to the fun part:

Unfortunately I haven't found a working method to get Google Play to work on the Epic without root. cobalt232's modded Play Store sort of works at most when paired with microG, but it is unable to install apps. Sideloading Play Store to system should be easy once rooted though. Copy the four APK files from this ZIP to /system/priv-app using X-Plore or some other root file manager, and make sure the permissions are set to 644:

Once that's done, restart your device, then check your parental controls menu to see if Google Play store runs correctly:

From there you can now download the likes of YouTube Kids and other such applications which aren't available on Amazon or LeapFrog's own app store.

I also recommend using an ad blocker such as AdAway to keep those pesky banner ads from showing up on your kids' games; don't get me wrong, those ads are there for a reason, but they are sometimes so pervasive that it can be harmful to your kids.

OTA flashable ZIPs

Wed, 10 May 2017 07:27:55 +0000

The following files are incremental updates used to update an existing system to the latest build. No known scatter or flashable ZIP files for a full system image exist.

Code:

Thought they might be of some use to us, but the thing here is that no known official full system images/scatter files exist so far. Not unless some LeapFrog engineer steps in and uploads the latter for us developers to play around with.

[ROOT] Some more LeapFrog Epic tweaks

Wed, 10 May 2017 07:25:05 +0000

I know this involves root, as not all parents are up to it, but in case you feel like your son or daughter's LeapFrog isn't cutting it, I found out a few more tweaks which should add a bit more functionality and make it more usable.

As I said earlier, this requires root, which can be done using one-click utilities. The PC version of Kingoroot should do the trick. Once you root your device, you'll also have to install Xposed for the other tweaks to run.

Bring back the recent apps button
I'm sure you've noticed that the navigation bar on the Epic lacks the recent apps button for some reason. 'Tis uncertain as to why, but my hunch is that LF decided to dummy it out to keep children from opening it by accident. Fortunately, the ROM is still largely AOSP-based so it's just the matter of using Xperia/AOSP Navbar Buttons to gain back task switcher access. GravityBox for Kitkat seems like a viable option as well, though I haven't tried it myself yet.

Home sweet home
Ever grow tired of the KidLauncher? That rather infantile app drawer you or your kids are subjected to every time you play with the Epic? For a while I thought it's a matter of modding the framework files to get alternative home screens to install, but turns out it's no different from restoring SD card read-write functionality.

Assuming you've rooted your device already, mount /system as read-write using either ADB or Terminal:

Code:
mount -o rw,remount,rw /system

Once that's done, navigate to /system/etc/permissions then open tablet_core_hardware.xml using a text editor. Look for the following lines:

Code:

...then replace the commented settings with this:

Code:

Save your edited XML file, and then reboot. If done correctly, you should be able to install any home launcher you want. However, you'll have to freeze/disable KidLauncher and Launcher using ROM Toolbox or some other utility for your favourite launcher to work as default.

There are some caveats to using an alternative home screen though. One of them is that the navigation bar may disappear or that some of the soft keys may refuse to show up upon running certain apps (e.g. LeapFrog games). A workaround would be to open up App Manager for the missing keys to appear again. Another issue is with user profiles - as the login screen is built into KidLauncher, disabling it would render your children's profiles (and thus time restrictions and other parental controls) useless, plus rewards and other items earned may not show up (I presume this is due to the alternative home screen being counted as a different "user"). One could try using a third-party parental control panel app, but that would require another setup phase as it isn't weaved into LeapFrog's own parental controls service.
