[Fire General] hobojester:
I've spent the past 3 weeks pretty solid working out how I want to transform the 3 Fire's I got for $35 for my boys, 10, 8, and 4. I figure I'd post where I've finally landed along with some other things I've tried both with success and failure, and hopefully save some people some effort. I'd suggest reading through this before you use it as a stepbystep guide to make sure this works for you. I apologize if it's a bit jumbled, but everything should be here for you to convert your Fire. Again, I'd suggest reading through the whole thing to come up with a plan of action for you.

Goal: Turn this Fire into a glorified gameboy, used ONLY by kids, not shared with parent(s) and child

On 5.1.1

Assuming you've purchased an SD card, you will want to repartition in preparation for moving files and content.

Pointers for this:

Make two partitions, 1 which is about 70% of the card formatted as Fat32, must be a PRIMARY partition.

Second partition will be the remaining space, make it ext2, must be a PRIMARY partition. (From what I can tell the reason people suggest using ext2, and not 3 or 4, is because with 3 and 4 there is some built in backup and recovery operations which is great for when you're running a full Linux operating system, but for our purposes all it does is cause more writes which in THEORY will shorten the life of your SD card)

I formatted the Fat32 partition as the first partition, and the EXT partition as the 2nd. Not sure if the order matters or not, but I've had no problems doing it this way thus far.

Note:

During initial setup, don't bother with multiple user profiles (reasons explained later).

Using root junky's super tool (Thanks root junky, you made this all possible!!! http://rootjunkysdl.com/?device=Amazon Fire 5th gen&folder=SuperTool) do the following:

Root

Prevent OTA

Install Google Play

Install NovaLauncher (this is important if you're not going to use the built in Kids Mode in FireOS)

In Google Play Store download the following:

Link2SD (This is assuming you've purchased an SD card)

Kids Place - The VERY SIMPLE reason I went with using this app (which essentially becomes an alternative launcher) instead of using the built in FireOS's profiles and kids mode, is because the built in kids mode will ONLY allow you to use apps which you've downloaded FROM the AMAZON app store. I understand why they do it this way, I mean, the whole point of the fire is to keep you inside the Amazon ecosystem after all. But, I have MANY games I've paid full price for on Google Play that are appropriate for my kids. Since I can't put them into the kids profile built into the FireOS (If anyone can link me to a guide which is different, I'd love to hear about it) I couldn't use the built in stuff. In addition, the built in kids mode really is a pretty awesome feature on the fire, but the icons are freaking huge and kind of a waste of space.... going with this alternative method of Kids Place gives you smaller icons therefore you can "shove" more icons on a single view. Icons which take up half the screen are great, but if you're a dad like me who's going a little overboard and putting 100+ games on these things, it'll be a bit of a pain to scroll through them for your kids using the built in profile in the OS.

Note:

You can get Link2SD from the Amazon app store, but the version there is older than what's in Google Play and ultimately didn't work. Once I got the Google Play version, worked like a champ. NOTEx2: For whatever reason (this was frustrating for me to figure out), even though I partitioned 70% of the 64GB Samsung microSD to Fat32, and the other 30% I partitioned to ext2 (BTW I did the Fat32 first and ext2 second... not really sure if it matters the order or not but that's what worked first time for me so I went with it), when I launched Link2SD and it asked me which partition to use, I had to choose ext4 for it to finally work. Choosing both ext2 and Fat32 would both result in basically it saying: "yeah, you chose the wrong one punk" (or whatever it says).

Kids Place - similar to the one above, there is weirdness in the version on Amazon vs Google Play. On Amazon it actually claims the version there is slightly newer than Google Play, but when I'd launch apps on the one I got from Amazon it would kill the WiFi for that app. I realize that this is a built in option into Kids Place, being able to choose WiFi on or off per app (which is really cool), but the one from Amazon seemed to do it when and how it wanted instead of what I was telling it to do. Google Play's version had no such problems.

(( A word of caution using Link2SD's "feature" of being able to "Link Internal Data". DON'T DO IT. I've not been burned HARD CORE by it. The symptom is that if you POWER DOWN, and POWER ON the tablet, Apps go missing. Through reading and troubleshooting, it appears via this forum (http://androidforums.com/threads/link2sd-missing-apps-after-reboot.858565/) that the culprit is when you choose the Link2SD option to "Link Internal Data" to the SD Card. There's even a nifty batch way to enable it on ALL apps. Well, after powering off and powering back on the tablet (after I was COMPLETELY done putting on 150 games), when it came back up I only had like 15 apps on it. Everything else was POOF, gone. I've noticed sometimes after a power cycle like that the apps might take a few moments to 'come alive', but even after 15 minutes of waiting I had nada. Went in search and found I'm not the only one. I've now since completely redone (including reformatting the SD Card) all 3 Fire's and so far after multiple reboots, I've not lost a single app. So for now at least, this does seem to be the problem ))

You will need to spend the $2.35 on Link2SD Plus (striking out due to my caution above, that being said I'm glad I threw this guy $2.35 because my tablet would basically be worthless without the app), and after you install Kids Place, you'll need to upgrade to premium for $4.99. Here's why:

Link2SD - Plus - This is what allows you to automatically move files and content to the SD card when an app is installed. This is mega important to me because that piddly 5.x GB of usable space gets eaten up ridiculously fast otherwise. Dive into the settings once you have plus, and just go turn everything on. Auto move everything. Be sure to go into all menus and sub menus.

Kids Place - The premium features is key for me. For example: A) You can make this app launch upon reboot, thus it basically "forces" this into a kid only/friendly device. If your kids are sneaky, or bored, they'll try to break out of Kids Place. Then they'll delete apps, make folders, sabotage they're brothers devices, etc. B) You can change the name that's displayed on top from "Kids Place", to something else like their name, give them a fun nickname, whatever. For my 10 year old he won't feel like it's just a little kid thing. C) You can do this part without premium, but it's critical for me to mention it: You can change what the home "button" does so that it directs you back to Kids Place instead of the regular home launcher. The reason you need to install NovaLauncher above is because if you still have the stock firelauncher, you can NOT replace the home button with another launcher otherwise. [Word of caution, if you enable the 'background' premium feature, Kids Place is still running, just more in the background. Took me a few minutes to figure out that's what I had done. I kept thing something was wrong and wondering when whenever I launched Kids Place it kept asking me if I want to shut it down or go into settings.... it's because it was running the whole time already)

Once you've done all that, simply download apps (Amazon Underground still seems too good to be true, but I'm hopeful), sideload apps, get apps from Google Play, then go into the Kids Place settings and choose which apps you want (Manage Apps).

Other things worth noting:

SlimRom. So, this is cool. It's fast, and pretty awesome. For me however, at the end of the day, it didn't make sense to introduce something in addition that could go wrong. If you're like me and you have no intention of using this device yourself and you ONLY want this to be a device for your kids, I don't think SlimRom is worth putting in. If it's a shared device, it might be worth it. The only thing I really forgot to test when I had put SlimRom on one of the devices was how the Amazon App store would work, and whether or not the device would be recognized properly with the Amazon Underground portion.

That's it, I hope you find this helpful. I welcome any feedback or suggestions on how to make this a more gooder guide for anyone like myself who's first jump into amazon tablets has been these fires. They truly are AMAZING devices for the price.
