It's fine, I'm not upset, I was simply pointing that out. And no, it wouldn't appear the same because Huck and I opted for a different brand/codename for the device compared to what was originally used (by the stock ROM). Also, I'm not asking for my name to be on a bazooka recovery; I just want you to link to the sources you used to build the recovery (if you use our sources, that's it. If you've made your own, feel free to do whatever you want.), it's as simple as that. After all, TWRP is open source, isn't it? That's all I have to say on this. I won't continue this discussion here to avoid flooding the thread.​

[Android General] rejul:
One last clarification , I didn't post on several threads (out of 2, one for this , one of my device) , other one posted isn't exactly same based on your words.
[Android General] TripleLLLGaming:
alright. i'm finally back on this forum. still having issues, unfortunately. i recently switched to arch linux and i am now using it as my main pc. i've tried to do a readback of emmc/rom0, but to no avail. i'm assuming this is a drivers issue, but the device was detected on windows, but not on linux. trying to find mediatek usb drivers for linux, but i haven't found any yet. i've downloaded the stock rom and everything else. loaded up the scatter file, added the readback menu entry with the correct hex addresses, but the readback does not start. does the leapfrog epic have like a fastboot mode that is usually in most versions of android? or would i need to boot into recovery mode in order to do readbacks and/or flashes? any help would be appreciated.
[Android General] blakegriplingph:
I've only managed to successfully pull this thing off on Windows so you may have to temporarily use Windows 10 for that.
[Android General] TripleLLLGaming:
alright, thanks ^_^
[Android General] TripleLLLGaming:
alright, so... i'm on my windows computer. plugged in my epic (which is turned off, still not sure if it needs to be in recovery mode or not) and ran sp flash tool. loaded the emmc scatter file and tried doing a readback. no success. i think it might just be me being stupid? i don't know, man.
[Android General] blakegriplingph:
Did you check if the drivers are installed correctly though?
[Android General] TripleLLLGaming:
oh, i actually didn't think of that. how would you check that?

EDIT: gonna try using the driver installer executable. don't know why i didn't try that to begin with -_-
[Android General] TripleLLLGaming:
alright. turns out the driver executable probably wasn't what i was supposed to do. downloaded the signed drivers. how the heck do i install these?
[Android General] TripleLLLGaming:
nevermind. found out how. still, my tablet is not being recognized by windows. i'm on windows 11, could that be the issue at hand? cuz when i open device manager and plug my tablet in, no device shows up.

EDIT: looked at a reddit thread, says the only one that'll work is the one that CAME with the tablet. is this true? i can't exactly find it since this tablet was forgotten about for the past couple years and i had no idea that there WAS even a cable that came with it...
[Android General] randomguy3356:
I think I got mine about 5 or 4 years ago, but i still remember that it only had an ac adapter with the cable being part of it.
[Android General] TripleLLLGaming:
ah, okay. so, how did you get your epic to be recongized by windows? im on my windows 10 machine, but no matter how many drivers i install, it still won't show up in device manager. the drivers just refuse to install.
[Android General] TripleLLLGaming:
alright. just installed the drivers correctly. still not recongized. tried doing readback, but no dice...
[Android General] randomguy3356:
I installed a specific version of sp flash tool, which finally detected the tablet while turned off
[Android General] randomguy3356:
Ah yes, I installed sp flash tool ver. 5.1532
[Android General] TripleLLLGaming:
alright i'll try that. tysm! ^_^

pretty sure i DID have v5.1532, can't remember though.

also, any pointers for removing batteries? i've opened the tablet up before but haven't tinkered with it's terminals yet. never done such things before with any electronic for that matter...
[Android General] randomguy3356:
I flashed it with battery because without it just kept resetting
[Android General] TripleLLLGaming:
ah, so i should just keep replugging it until i get lucky?
[Android General] blakegriplingph:
Nah it should work with any decent USB cable. I used the one that came with my PS Vita and it flashes just fine with no issues.
[Android General] TripleLLLGaming:
alright. tried other usb cables, ports, and even other computers, but no device shows up in device manager. not even a preloader device. even with the device turned on it doesn't show the EPIC2 device like it did a couple months ago... is there just no other way i can get this to be recongized? i installed ALL possible drivers. unsigned, signed, but no dice.
[Android General] blakegriplingph:
Have you tried another computer? If that still didn't work then I'm afraid I won't be able to help you further.
[Android General] blakegriplingph:
Finally, with the help of a friend of mine who graciously volunteered to have his device's firmware dumped, here's the stock ROM for the MIPI sub-variant (EPIC4.user.2.x.xxxx) with a different LCD module and RK3326-S:

leapfrog-epicv4-firmware_MIPI : Free Download, Borrow, and Streaming : Internet Archive

Firmware dumps taken from the LeapFrog LeapPad Academy stock ROM, specifically the Rockchip RK3326 MIPI hardware revision.I've included two versions of...

archive.org

Remember that this will only work on that particular variant so be doubly sure that you have the right hardware revision for this to work; if the version on the about screen says something like "EPIC4.user.2.4.258.205241129" and if the LCD draws circles evenly without going too ovoid like this:

...then you should be on the MIPI revision.

However, if your firmware is on the 1.xx.xxxx release and the LCD does display circles like the one above, flash this ROM instead.
[Android General] TripleLLLGaming:
yeah, i've tried other computers, too. thanks for your help nonetheless ^_^
[Android General] randomguy3356:
keep trying, that happened to me. it took me 2 years but i got it
[Android General] blakegriplingph:
Persistence pays off. ;)
[Android General] TripleLLLGaming:
BINGO! got it recongized, even by my linux machine! here's the kernel buffers.
[Android General] TripleLLLGaming:
well, i screwed up. flashed the signed twrp image only to find out it caused boot looping, so i went ahead and tried to force shutdown. held it for more than 30 seconds and it still didn't turn off. i just went ahead and flashed the v1 rom. the tablet did not turn on. i can't even reflash stock recovery, because it just says it can't find the COM port, yet it worked earlier. however, i DID make a ROM_0 backup. how would i go about writing that backup to the tablet?

EDIT: just read one of huckleberry's forums. gonna use rom0split and try to rewrite the split imgs to the tablet.
[Android General] TripleLLLGaming:
welp. i can't even flash a single thing now. not even the split ROM_0. it still just says it cant connect/find the COM port. i know its not the usb ports because they worked fine before when i tried to flash twrp. think i might be screwed for now. any suggestions?
[Android General] TripleLLLGaming:
okay, so i tried another pc and i was able to flash the split rom_0 imgs. but, even then, the tablet does not boot. even tried removing the battery for a while and putting it back in but no dice.
[Android General] blakegriplingph:
Try flashing ROM_0 as a whole using Write Memory in SP Flash Tool. Assuming that the backup you made is from the tablet you just brick, you should be able to bring it back to life.
[Android General] TripleLLLGaming:
alright, i'll try that.
[Android General] blakegriplingph:
Indeed, considering how both the Epic and those white-box tabs you mentioned are more or less the same on a performance and technical standpoint. Of course a more practical parent would choose the cheaper model, even in spite of the fact that it has malware embedded in the device's system or boot partition. Then again most of them wouldn't be aware of that issue anyway.
[Android General] Kmlingo5:
Quick question, sorry if I am addi g to this thread by mistake! I have had this Epic tablet for a few months now. I have no problems installing third party apps to it most of the time, however I would like to add Google Play to it for ease of downloading apps. Has anyone successfully installed Google Play Store and Services? Thanks in advance!
[Android General] thenab0303:
My sister has the Epic for her son and asked me to try and put some apps on it for her baby. Tried looking for a root which was when i ran into this thread and then found out how to enable unknown sources to sideload apps. I could not find a way to put the Google Play Store on it but it wasn't a big deal. You can just use an alternative store, I used APKPure, it has pretty much everything the Play Store has and found a modded youtube app on xda that works without google services. Not sure if you'll come back to read this but hope it helped lol
[Android General] blakegriplingph:
Too bad MTK Droid Tools doesn't support the MT8127 which the Epic uses. I was thinking maybe someone can cobble up a CWM/TWRP image and install SuperSU through that, assuming LeapFrog didn't lock down the bootloader. That way you guys can proceed with flashing Google Apps on it and thus be able to sign in on Play Store.
[Android General] thenab0303:
I've been keeping an eye on this thread for such news and unfortunately I lack the knowledge to do such things, hopefully someone is trying
[Android General] blakegriplingph:
Epics cost more than twice here in my place (no thanks to import duties even when similarly-powered devices could be had for way less), so it's a stretch for me to buy one I'm afraid. Not unless if someone's willing to donate some $$ or a device for the lulz, that is. :P
[Android General] RAMChYLD:
Well, I tried using the Crackberry Google ID+Google Settings+Play Store combo meant for BlackBerry 10 (had a lot of success with that, so of course I'd try it here). Nope, the Crackberry Google ID app launches, allows me to try to check in, then crashes with a Null Pointer Exception. Maybe someone can take a look at the APK and create a derivative to make it work with generic Android? It would be a good way to go too, since it allows those who don't want to root their device to still enjoy the Play Store.

http://forums.crackberry.com/androi...berry-10-read-first-post-instructions-985344/

The Crackberry Google ID app was created by the user Cobalt, and he also made a few adjustments to the Google Play and Google Settings APK. They work flawlessly on both my Blackberry Passport and Q5. Not so much on the Epic. Maybe someone with some knowledge in this can work with him to make it work on unrooted Android devices too?

EDIT: Just looked through the instructions and I realized that I tried to check in before I logged into the Google Account. I'll try again tonight and see how it goes.
[Android General] blakegriplingph:
Wishing you luck on that one. Though I hope we could've done a ROM dump of the thing through MTK Droid Tools and SPFT.
[Android General] mands386:
If anyone is still here

I rooted and stupidly renamed the parentlock.apk (or something like that) to .bak to try and install a different launcher and now im stuck and cannot do anything, I tried factory reset but no luck

Any suggestions?
[Android General] blakegriplingph:
Are you able to access the device through ADB? If so, you could try to rename it back to what it was; otherwise you're SOL and you definitely need to flash a stock image back to it.
[Android General] mands386:
Do you know where I can find the stock image?
[Android General] blakegriplingph:
Not from what I know, though I'm sure someone would be willing to do a dump of the stock ROM which shouldn't be too hard to pull off.
[Android General] mands386:
So basically I'm screwed lol
[Android General] blakegriplingph:
You can say that, unless if someone has a ROM dump ready.
[Android General] shyshawn:
How do i access the ADB? I found how to do the factory reset at start but my problem was still not resolved so i did it again and made a mistake and selected the update with ADB but i dont have the ADB to send to the epic and now its stuck on the screen and nothing i do takes lets me out.
[Android General] ISITBRICKED:
Anybody ever figure out how to root this thing? Sounds like mands figured out how to root it(has a whole new issue now tho it seems). Just got this for my son a couple weeks ago.

---------- Post added at 06:15 PM ---------- Previous post was at 06:03 PM ----------

Got it rooted using the "kingoroot" apk...one tap super easy...verified with rootchecker. That site explains installing custom Recovery's as well. Will tackle that shortly.
[Android General] mixerpilot:
Did it work correctly after root? Any bugs with epic software?
[Android General] blakegriplingph:
Only prob is we don't have an SP Flash Tool-compatible dump of it. I could probably do one myself, but I don't have the device atm, and it costs an arm and a leg to get my hands on one.
[Android General] epic__fail:
I think I've managed to successfully get a complete stock ROM dump using read back on the SP Flash tool over the weekend.

Not had a chance to clean it up and find somewhere to upload but I'll try to get some time in between work and the little one to make it available as soon as I get some time ;)

It's my first Android device so thought it would be a bit of fun and it did keep me occupied for a few hours whilst I tried rooting, figuring out how to dump a ROM and working around the MTK Droid Tools not working off the bat.

For anyone wanting to root, I just used KingRoot which made that part a no-brainer 1-tap process.
[Android General] epic__fail:
I've posted it up on needrom. Not sure if there are better options out there?
[Android General] blakegriplingph:
That would be golden, though I assume it's a pre-rooted one, right?
[Android General] virtualcappy:
Any luck on the custom recovery? Seems like that would be the way to get gapps on there. Kingroot worked for me as well but there doesn't seem to be a supported recovery image. Anyone know if there is a version for a device with similar hardware that might work. I'm willing to be a guinea pig but not sure how to pick which twrp img file gives me the best shot.

Maybe I should ask the devs...
[Android General] ISITBRICKED:
I stopped at rooting it. Never got up the courage to try a custom recovery. What do I say to my 3 year old after I brick his tablet lol...
[Android General] blakegriplingph:
Not unless if someone is willing to donate an extra Epic to a developer or two. :P
[Android General] McSpiffy:
Has anyone been able to put Google movies & TV on this? I have been trying since I got it for my son in may and still no luck. I have like $80 worth of Curious George on Google play for him and I can't even put it on his tablet >•>

About write back custom partitions to epic

I now I also rooted, found all partitions info and made scatter file and then via read back in flash tool got all rom blocks backup. But then I tried to write my custom recovery I can't. Flash tool say errors. I tried many versions of FT and DA and drivers packages, windows 8 and windows xp pc, different cables and hubs but with not results.

Any advice from you may appreciate
[Android General] _Peek:

So you're in fastboot mode? Try unlocking the bootloader then, if you can.

Right now I am planning to compile a TWRP port, though I don't have a guinea pig to test said recovery atm. It should be trivial to do so though, especially as there's already an MT8127 recovery on Github anyway.
[Android General] cristihutch:
Not trying to hijack your thread or get you guys off topic lol, but I bought a leapfrog epic for my son for $15 off eBay - cheap because it's stuck in "demo mode". Does anyone if there is a trick to get into the normal settings (besides with the 419<backspace>27 passcode - only very limited settings -- unless there is something I'm missing) or another way to disable demo mode? I have tried volume up and power and tried resetting that way but it boots right back up into demo mode. I downloaded the rom mentioned earlier in this thread, can't install it through recovery tho, prob cause it's not rooted, but gonna have to research more on all this because Ive mostly worked on apples. But this can't possibly be stuck in demo mode forever.. Can it? If anyone has any suggestions or has dealt with one of these before I'd love the info. Thanks for any help anyone can offer!
[Android General] tierzastarrw:
i just got a leapfrog epic for my son today and have spent hours downloading apps from his old tablet onto here. after a while I get an alert saying the memory is full, so I go grab a mini ad card and pop it in, only to find out the leapfrog only lets you use the card for pictures and videos but not apps. If anyone could find a work around, that would be awesome.
[Android General] blakegriplingph:
Just got my hands on an Epic courtesy of [MENTION=3925770]StarbuxMcCloud[/MENTION], and right now I am trying to flash a retail ROM on this demo unit. For some reason the one epic_fail dumped appears to be spazzing out with that dreaded "BROM ERROR: S_SECURITY_SECURE_USB_DL_IMAGE_SIGN_HEADER_NOT_FOUND (6045)" message regardless of what tool I use. I'll let you know how this goes, but if anyone has a clue on how to fix those SPFT errors I keep on getting, please let me know.
[Android General] blakegriplingph:
You may want to unlock your Epic's bootloader. Problem is there is no way to get to ADB for fastboot mode to be accessed, and flashing the ROM as it is won't work as SP Flash Tool outright rejects the scatter package.

We do need a stock, untouched ROM for this as LeapFrog seems to outright refuse to supply one for us even if they did give away the kernel sources. Sure, the UI and other bits are proprietary, but it ain't like there hasn't been any leaks of ROMs from other brands.
[Android General] curtgordon:
Instructions for this

This is interesting.

Can you please tell me the instructions for setting up?

Thank you
[Android General] blakegriplingph:
Well, what do you want to do with the tab?
[Android General] RAMChYLD:
Well, I've volunteered to rip the ROM of my unrooted Epic for [MENTION=4092918]blakegriplingph[/MENTION] and I'm having some issues with this, since I've never messed with Android ROM before. I'm going to need some help with MTKDroidTools. I'm using the latest version of MTKDroidTools, 2.5.3.

I've installed the app to bring up the developer settings screen to enable USB debugging. I've installed the ADB drivers and edited the mtkdroidtools.ini file to include the MT8127 SoC as per Blake's instructions. However, MTKDroidTools just isn't seeing the device. I opened the ADB terminal and confirmed that the version of ADB that ships with MTKDroidTools does not see the device. I double confirmed by downloading a separate, newer ADB package from several sources and the newer ADB package does see the tab, indicating that it's an issue with the version of ADB that comes with MTKDroidTools.

Herein lies the rub: I'm unable to get the newer version of ADB to play nice with MTKDroidTools. I tried replacing the version of ADB in the MTKDroidTools folder, but then that only leads to MTKDroidTools complaining that "It's Impossible to start ADB" and quitting. Task manager confirms that ADB is running however. But it seems that MTKDroidTools is somehow convinced otherwise.

Someone else posted to this thread that they've successfully gotten MTKDroidTools to see the Epic. Is there a development version that I'm not aware of? Or am I doing something else wrong?
[Android General] blakegriplingph:
Which is strange as some have managed to rip ROMs off MT8127 devices, and yet [MENTION=543591]RAMChYLD[/MENTION] is unable to get MTK Droid Tools to work despite sending him a working build. Something must be off with his config.
[Android General] RAMChYLD:
If someone could patch MTKDroidTools to work with newer versions of ADB, that would be great.
[Android General] blakegriplingph:
If only someone here with a retail Epic would be kind enough to help us out. I can't do it on my end as I couldn't get ADB to kick in on my demo unit.

[MENTION=4092918]blakegriplingph[/MENTION]

What is the latest version of the ROM for this device?

Is it possible to enable USB debug in the device?

Is there some special procedure to unlock the bootloader?

If someone want I can provide you the boot.img (of the needrom ROM posted on first post) unlocked to flash it with Flashtool.

[MENTION=543591]RAMChYLD[/MENTION]

Please didn't make OT request.

You cannot make a request here to patch MTKDroid because this is not the MTKDroid thread.

And also please take care that as I explained in MTKDroid thread the problem is not MTKDroid but probably your device that cannot enable USB debug that is necessary for MTKDroid.

Try to use the adb.exe command in bin subflder of MTKDroid 2.5.3 mod by bovirus (please use now for teh future this version). Open a dos promp in bin subfolder and type the command

adb devices

to check if this adb recognize your device.

Try to to load/install and enable adbinsecure by Chainfire to check if MTKDroid recognize your device.

One time that you install it in the device makre the check with adb.exe (in bin subfolder).
[Android General] RAMChYLD:
[MENTION=637263]bovirus[/MENTION] understood. Sorry I posted OT. Was at the end of my ropes and can't make any progress. In fact, [MENTION=4092918]blakegriplingph[/MENTION] and I just spent around two hours in TeamViewer session experimenting a while ago and still getting no success.
[Android General] bovirus:
[MENTION=543591]RAMChYLD[/MENTION]

No one can make changes to the MTKDroid, because is already compiled, are not available teh sourecs, and the russian author disapper from teh forum.

If you want that I can help you, please help me.

Follow my explanationand my requests and post teh reply not as generic answer, but step by step with the deials of the test that you did and wth the results.

Please post in details you ROM version. You can get in "Settings" -> "Info about the device".

Did you make the test with bin\ad.exe (command adb devices) of my MTKDroid 2.5.3 mod (please did't make the test with the original MTKDroid 2.5.3)

Did you install and enable adbinsecure (https://xdaforums.com/showthread.php?t=1687590) in the device?

Did you re-test bin\ad.exe (command adb devices) of my MTKDroid 2.5.3 mod (please did't make the test with the original MTKDroid 2.5.3)

To test my adb version you should open a DSO prompt in teh bin subfodler where you unpack my MTKDroid 2.5.3 mod bovirus version.

Check tha in this fodler there is my adb.exe.

type the DOS command

adb kill-server

adb devices

Post the result. Thanks.
