Having recently purchased a TF300T with intent to customize the hell out of it, I ran into a big problem. There wasn't one definitive guide for my general case, some of the steps I read weren't completely clear, and I often had to put pieces together from multiple guides to get where I wanted. Halfway through the process it occurred to me that sharing my experience in form of a guide could give the community something I wish that I had when I began. So enough with the intro, let's visualize the process before we begin.
This guide is for new owners of TF300T devices that have Jelly Bean 4.1.X preflashed from the factory.

If your tablet has 4.2.1 Android version from Asus, DO NOT FLASH A RECOVERY THAT WAS ACTUALLY MADE FOR 4.1 TABLETS! You will end up on a PERMANENT BRICK with no solution until now. You won't be able to use fastboot ever again. You won't be able to flash anything ever again. You will be stuck with a bricked tablet!
If you are looking for a Recovery for a 4.2.1 bootloader (and a complete guide for updating), read this thread: http://forum.xda-developers.com/showthread.php?t=2187982 Don't do it with any other tutorial: they are for 4.1 bootloaders!

For those curious...
My TF300T was one of the Champagne Gold models purchased from Groupon with a serial that begins with C9. I recall seeing a user with a Champagne Gold from Amazon that still had ICS. If you're still on ICS, this guide isn't for you-- Read up on NVflash and decide if you want to take advantage of it BEFORE you upgrade to JB.
Here's an overview of what we will be doing:

Unlock the TF300T
Backup apps, app data and files (Recommended, Optional)
Install ClockworkMod Recovery (soon to be replaced with TWRP; I gave in)
Root the TF300T (Optional)
Backup your stock Asus ROM (Recommended, Optional)
Flash a Custom ROM
Backup your working Custom ROM (Optional)

This guide has been made with the total android noob in mind. Having only owned an android tablet for a week, I too am an android noob. On the flipside, I'm no noob to hardware and software exploits and modifications. I've tried to make this friendly for any type of noob, but there are a few instances where I expect basic menu and Windows 7 navigation skills.
ClockworkMod Recovery doesn't appear to have a "Shutdown" function, nor does it display current battery level-- for this reason, the recommendation and warning to have a battery charged to at least 60% is extremely heavy. The worst thing that can happen to any device is usually an incomplete flash. Don't let it happen to you-- start charging your TF300T NOW.
I have seen reports that "Fastboot" doesn't work properly on Windows 7 64-bit. This guide addresses that issue, as I also encountered it. If you don't know what "Fastboot" is, in the words of an admirable comedian, "You gonna learn today". Don't worry about it for now!
Your device came with JB-- you didn't miss the bus for NVflash. In your case, the bus never came.
I am not responsible for any damages caused to (but not limited to) yourself or your device.
Even if you think you're pretty good at figuring this stuff out, stick to the directions as close as possible.
If you love tweaks, you're going to love your custom ROMs.
Let's get started!
Unlocking Your TF300T
Click to expand...
Click to collapse
WARNING: Unlocking your TF300T will void your warranty. If your device breaks or fails under normal use, don't expect Asus to pick up the tab! Be aware that once unlocked, it cannot be relocked.
There are two ways you can go about this-- Either download the official Asus unlock utility for Windows or download the .apk and install from your tablet (Asus utility still working! I successfully unlocked mine on JB 4.1.1). I chose to download the .apk and install directly on my tablet, therefore this is the method I will cover.
To download the .apk file, scan the QR Code below with Barcode Scanner (free; on Play store) and open the URL to the Asus Support page for the TF300T. Alternatively, if you are viewing this thread on your TF300T, you may simply tap the code below.
On the Asus Support page, select "Android" as your OS. The page will reload and present you with a list. Click on "Utilities", then after it has loaded, download the Unlock Device App. When it is done downloading, a notification will pop up in the lower right corner. Click on it to install the Unlock tool. You'll also be able to open the app immediately after the install completes-- open it now.
After scrolling to the bottom of the End User Licence Agreement, select the checkbox indicating that you agree to those terms. You should now have access to the slider that will unlock your tablet. Stay connected to your wifi and unlock when ready. The unlock will not work without access to the internet.
If I recall correctly, your tablet should reboot. Just let it do what it wants. After it's done doing it's thing, take this opportunity to make backups! when you and your tablet are ready, we'll continue on to the next step.
Setting Up The Android SDK and Installing ClockworkMod Recovery
Click to expand...
Click to collapse
Perhaps this was the most frustrating part of my experience-- Installing the Android SDK went fine when I could actually find the .exe download. After that it was a matter of getting the drivers for Fastboot working properly. I was able to narrow it down to a problem for users of Windows 7 64-bit.
From your PC, go HERE, scroll down and click on "Download For Other Platforms". Scroll down more and under the "SDK Tools Only" downloads, you should find a download that looks like: "installer_r##-windows.exe" where "##" is the revision number. Download this .exe and assuming Windows is installed on C:\, install it to either "C:\tools\android-sdk" or "C:\android-sdk". If Windows is not installed to drive letter C, replace the drive letter with the correct letter for your system. Do the same when following the command prompt examples that follow.
Open the Android SDK Manager. Search for "SDK Manager" in the start menu and you should find a result with the same name and a little android icon. Once it's open, you'll be presented with a list. Check the box next to the "Tools" folder, then expand the "Extras" folder and check the box next to "Google USB Driver". In the lower right corner, click "Install packages...", agree to all when ready and begin your downloads.
In the settings application of your tablet, go to the "Developer options" tab near the bottom. Ensure that the switch in the top right corner is in the "ON" position, then under the "Debugging" header, enable "Android debugging". Read the following carefully before you continue: Shut down your tablet and connect your USB cable. Hold the power and volume down buttons at the same time. Keep holding until you see a menu. The menu will consist of a few items, among them there is "RCK", a USB icon, an Android icon, and a "Wipe Data" icon. Tap volume down until the USB icon is selected, then press volume up. Cross your fingers and hope drivers install automatically.
They probably won't, so have windows look in the \android-sdk\extras\ folder. It should say the drivers installed successfully. Either way, open the start menu, and right click on "Computer". Click "Manage", then in the left hand pane of the new window, click "Device Manager". The "Other Devices" section may be already expanded in the center pane. If it is, look to see if "Fastboot" appears in that section with a yellow exclamation mark.
If it isn't there, you shouldn't be worried-- check for a section called "Android Phone" or "Portable Devices". Look for a device called "Android ADB Interface" or "Fastboot". It shouldn't have a yellow exclamation mark next to it.
In the event you have the device appearing with a yellow exclamation mark next to it, go HERE and download PdaNet. This was my remedy for this error. Unplug your TF300T from your computer and install PdaNet following instructions. During the install a warning will appear to install unsigned drivers. Install the driver anyway, and let the installation finish. You can now plug your TF300T back in, and it should be recognized automatically. Just in case, hold the volume down and power buttons again until your tablet restarts and you see your hidden menu again. Once again, tap volume down until the USB icon is selected, then press volume up again to select it. Check the Device Manager again and you should find the "Android Phone" section at the top. Within it, you'll find a device called "Android ADB Interface".
Now that we have your tablet and computer set up nicely, we can finally install ClockworkMod (CWM) Recovery. Go to THIS thread and download the attachment called "recovery-jb.img" (thanks XpLoDWilD!). It is VERY important that you download "recovery-jb.img" as this is the version for users with Jelly Bean bootloader!
Rename the file you just downloaded to "recovery.img" and place it in \android-sdk\platform-tools . In Windows 7, open the Start Menu and search for "cmd". You should see a result called "cmd.exe". Right click that result and click "Run as Administrator". Now type the following commands into the new command prompt window in order to flash CWM Recovery:
Code:
cd C:\tools\android-sdk\platform-tools\
fastboot -i 0x0B05 flash recovery recovery.img
DON'T unplug your tablet!! Don't close the window either! Wait for the command prompt to finish what it's doing, then you can type the final command:
Code:
fastboot -i 0x0B05 reboot
Your tablet will reboot. Once it has fully rebooted, shut it down and hold volume down and power again to access our tablet's hidden menu. This time, instead of selecting the USB icon, select "RCK" and press volume up. If I'm not mistaken, "RCK" stands for "ReCovery Kernel". ClockworkMod Recovery should load up. If it doesn't, then you were not successful in flashing CWM. If it does, then you can go to the Backup and Restore menu and create a backup.
I was overconfident when I went through all this, and I didn't make a backup-- for me, I wasn't able to get my SD card detected (64GB fat32), but even in this case you should be able to make a backup to your "Internal SD card". Unfortunately, you are on your own for this step. Make sure that you transfer this backup to your PC after creating it. You may need to disable Developer options in your TF300T's settings before you can transfer files over again.
In THIS post, XpLoDWilD gives instructions on how to Root your tablet. If I'm not mistaken, this applies to users who are using a ROM that does not already have root. If you care about Root right now, you can go ahead and flash his attached .zip file using CWM to your TF300T.
When I did this, I selected the .zip file with CWM and then went back to the main menu to select reboot. CWM then prompted me that it needed to fix permissions in order to keep Root. I tried it both ways-- first I let it fix permissions, then used a Play store app to check for root. Test came up negative, so I tried again without allowing it to fix permissions. Negative again. I tried again, allowing it to fix permissions again and then left it alone. If you are successful in rooting your TF300T, you can use Titanium Backup to backup your device later. However I used an app that did not require root that worked fine. The choice is yours.
Flashing a custom ROM
Click to expand...
Click to collapse
Now it's time to find a custom ROM to flash. For my guide I will cover Baked TF300T Blackbean #6-- Based on CyanogenMod10, and quite a nice upgrade from the stock ROM. The only downside I found is the Asus App Backup application is not included and cannot be installed. I'm unsure why this is the case-- I have even attempted to install it via CWM with no success. If you need this app or the App Locker app, I suggest you choose a non-CM10 ROM. You are on your own in deciding an alternative, but I have heard great things about CleanROM and I seem to recall reading that these incompatible Asus apps work on it. Don't take my word for it-- do your own research to make sure!
It should also be noted that ROMs like Blackbean #6 have some potentially dangerous settings that can make a power user salivate profusely.

Okay, so it was his uncle, whatever. But either way, if you're going to install this ROM (or any other with overclock tweaks), BE CAREFUL when selecting different settings for CPU speed and overclocking. I used to overclock my PC as a hobby and pushed a 1.8GHz CPU to 2.77GHz on air cooling.. The thing I learned in the process is if you don't have the proper settings, your computer becomes unstable and weird things start happening. Data corruption, clicking the Start Menu does something crazy and unusual, PC crashes randomly, etc... Some of these errors are due to insufficient cooling-- a problem you cannot remedy when working with a portable device.
Assuming you are new to this tablet like I am, use this rule of thumb when dealing with foreign and potentially dangerous things: DON'T TOUCH IT until you understand it. Then when you understand it, understand it again. Then when you feel you've understood it twice, take baby steps. It's like jumping up a cement set of stairs-- you're definitely not going to try to jump five steps in your first attempt, unless you want to risk smashing your face and bloodying yourself up. Take it one step at a time-- make sure you can land on your feet before deciding to go further.
There's a lot of other options Blackbean #6 has that the average user can still appreciate, so ignore those overclocking/CPU stuff and focus on the other tweaks. Nova Launcher is included and is pretty sweet. I upgraded to Nova Launcher Prime and feel it's worth the extra $4, but I'll leave that for you to decide. There are more options than merely Nova Launcher alone, and not all of them have a price tag.
Without further adieu, let's download the Blackbean #6 ROM and Gapps. Head over to THIS official release thread for the downloads. The names of the files you want are:
baked_tf300t_blackbean-6_jb-bl_b6.zip
gappsinverted-jb-20121029-signed.zip
Put them into a folder called "bb6" and copy the folder over to your TF300T. If your SD card is working in CWM (from CWM, go to the "mount" menu and try to mount SD card), copy the folder to your SD card.
NOW is the time to do any final backups before your fresh ROM install! I recommend "App Backup & Restore" on the Play store. If your tablet is rooted, you can also use Titanium Backup. Both will work fine, though generally speaking people seem to prefer Titanium Backup. People also seem to prefer TWRP over CWM, but I personally find the design unappealing. More importantly, I could only find a proper guide on installing CWM on a factory flashed JB TF300T.
Once you've made your backups, don't do anything until these backups are safely transferred to your PC! Don't forget to backup your music, movies and photos...
Now that you're 100% confident you've made all the backups you need and your battery is well charged and ready to go, let's flash your custom ROM! Shutdown and enter our hidden menu you should be very familiar with by now. Boot into CWM (with RCK icon from hidden menu selected, press volume up), then press volume up/down to navigate.
READ THE FOLLOWING SECTION BEFORE DOING ANYTHING ELSE:
Select "install zip from sdcard" and tap power. If you placed your "bb6" folder on your SD card, tap the power button once more. If it says "Can't mount /sdcard/" in the bottom left corner, then select "choose zip from internal sdcard" and tap power. Earlier you should have put your ROM and Gapps in a folder called "bb6". If you can't find this folder in either the SD card or internal SD card locations, GO BACK, reboot, and make sure you put the folder on your TF300T or your SD card. You should also make sure that the ROM and the Gapps file are inside that folder as well. Do NOT unzip them! They are just fine as they are. We are NOT flashing the ROM and Gapps yet, we are merely making sure they are there before you wipe your tablet. If the files are there, go back to CWM's main menu.
Select "wipe data/factory reset" and tap the power button. Confirm that you want to wipe, wait for it to finish.
Now select "wipe cache partition" and press the power button. Confirm that you want to wipe, wait for it to finish.
Go back to the main menu and select "advanced" and tap power, then select "wipe dalvik cache" and tap power. Confirm that you want to wipe, wait for it to finish.
Don't worry! Your ROM and Gapps should still be in your bb6 folder. Navigate to "install zip from sdcard" again, and let's make the magic happen. We are going to install the ROM first, then install Gapps. Only after both the ROM and Gapps are installed will we reboot our tablet.
So select the ROM first, confirm that you want to install, wait for it to finish. This one will take a long time compared to the Gapps. Just be patient and wait, even though it looks like it's not doing anything.
Then select the Gapps, confirm that you want to install, wait for it to finish.
Finally, reboot your tablet and cross your fingers. You should be greeted with the sweet victory of the startup animation. Go through the first time setup routine, and make sure the tablet works. From here you can optionally backup your custom ROM, but I recommend getting your settings the way you like them before you backup.
Give yourself a pat on the back--you survived! Hope this guide helped someone out-- I was able to sort through my problems fine, but I felt it important to share my experience. I know I couldn't have been the first to hop through these hoops anyway.
Congrats on your custom ROM Transformer Pad. Enjoy your tablet.
P.S. Questions? Comments? Suggestions? If you have any of the three, feel free to share! If it's a suggestion, please PM me and I'll see about making edits to my guide. All are appreciated, and especially anything that clears up any uncertainties I've expressed.
Special thanks (individuals and groups I owe credit for my process):
Drgravy, Team Baked, and everyone who wrote code that was used in the Blackbean ROMs. Blackbean #6 is my first custom ROM, and so far it's been great!! Keep up the awesome work!
XpLoDWilD, for CWM Recovery + Root on TF300T. These files and instructions were the major keys in making my endeavor a success
I also want to send out a big thank you to every other individual and team who has released a custom ROM for the TF300T-- admirable work, and far more than I could ever do. Thanks for giving us options and making us excited to have a customized tablet!
(....And many more! Currently in finals week (yikes) and can't recall everything right now-- will add more as I remember)
It's a shame that such a well written guide has so little thanks. Have mine.
Sent from my ASUS Transformer Pad TF300T using xda app-developers app
Very nice. hopefully this helps people just getting the tf300.
note, if you want to install TWRP recovery instead, your command will change accordingly, just make sure you type in the exact file name you want to flash. so if your recovery file is named twrp.blob:
fastboot -i 0x0B05 flash recovery twrp.blob
Thanks!
Your guide helped me a lot. I had problems only with root. Flashed 4 times, but always got "no root acces". Finally, I downloaded root package from here http://forum.xda-developers.com/showthread.php?t=1845377 and it works well
is there any way around that "unknown error..." when i try to use the unlock app yet?
I keep trying but the same error message keeps coming up

Is your tf300 new? first hand? or have u ever sent it to asus for repair before?
Well written, well thought out instructions. Many, many thanks!! I'm still having some trouble though. I get stuck once I download the unlock app, open it, agree to the EULA, then another warning appears that is a black screen white text and a yellow triangle. Nothing happens after that. There are no buttons to agree, no checkboxes, nothing happens. Any advice?
*UPDATE* Figured it out. Be sure to sent the font in settings->display->font size to small, then you will see it. The large font pushes the agree button off the bottom of the screen.
It would be great if CWM in this OP were replaced with TWRP. Many are having issues with CWM. Me being one of them. I flashed TWRP with fastboot and no more problems!
I agree with the post above. Sad that such a well written post has so little thanks. :good:
thnx for this amazing guide, but I am still unsure of this guide will work for me.
I am from Holland (Europe)
specs from my ASUS Transformer TF300T:
Android 4.1.1
Kernel 3.1.10 ([email protected])
Buildnr JR003C.WW_epad-10.4.2.18-20121122
Pad EC Version PAD-EC20T-0216
My question is...will this guide also work for me? ...since I have JB 4.1.1 & build 10.4.2.18
I am also worried about the fact that this guide in for an american(?) transformer I gues...so do I need other files then the files mentioned?
I would love to have ROOT and install a custom rom and remove bloatware etc.
thnx for the help in advance!
Thank you so much, perfect for so many people here.
Can you edit it with TWRP? I would use this right now but as above poster said there have been issues with CWM so don't want to try it.
P.s. i got mine from groupon too

Yes, it will work, I've tried it. But i suggest you use TWRP custom recovery though. CWM has high chances of getting bricked.

Could you also please add a NOOB tutorial for installing TWRP Recovery (this forum is very confusing in getting the right tutorials / avoiding outdated tutorials which would brick my TF300T etc)?
Example:
quote from XDA forum in TWRP topic: "The fastest and easiest way to install TWRP is to use the GooManager app" <--- GooMnager needs ROOT so I can't use this method?
My ASUS TF300T is completely untouched & unrooted still and don't won't to mess it up.

www.mediafire.com/?7v1gwbbzqzvzto7 <- fastboot and twrp, the twrp is out dated so if you want you can download new one from twrp website.
2)Extract the recovery with fastboot files zip and open a command prompt in the same folder of the adb and fastboot files (you must click the fastboot and adb when extracred and i suggest you put your extracted fastboot and recovery zip in C:\(foldername) and then open cmd)
3) Reboot into the bootloader of your tablet, type: adb reboot bootloader
4) When your tablet has reached the bootloader navigate with volume down to the usb icon and press volume up to confirm.
5) To flash the recovery type:
fastboot -i 0x0b05 flash recovery tf300t-jb.blob

- Made a second (COMPLETE) backup of the now ROOTED system with TWRP
- Tried installing the latest "Cleanrom 3.01 Inheritance", but got the infamous "bootloop" too...the rom has been pulled down from the forum till that is fixed ( I thought I had done something wtong flashing a custom rom, but actually a lot of others had the same problem)
- Waiting for a "bootloop fixed" Cleanrom Inheritance 3.02....and gonna try flashing it again.

i never backup.... I only backup app using titanium backuo, if something on the rom goes wrong i just reflash latest firmware from asus website. If you like custom roms, i suggest you use Energy Rom if you want OC or Hydro rom if you want just modified stock rom with better performance.
I have a problem while I try to run the flash recovery command. I have done all steps prior to this.The only difference I see is in device manager I get "ASUS Android Devices". Now, the error I am getting comes after trying to run the command, I get "error: cannot load 'recovery.img' No error" . I have also tried the pdanet solution. Thank you for your help in advance.
Stupid question... but I am going to ask it. Having never rooted my TF300 it is on latest firmware will this guide still apply to be even though I bought my device running ICS but have updated to latest firmware? Have never rooted tablets before so all new to this.

It will work as long as you are using Jelly Bean
So I've bought myself a new Nexus 7 and to my surprise the version of android out of the box was 4.2. After about an hour it asked me to download the "new update". I pressed on it and it said, install the new Android 4.2. I was a bit confused here, why it wanted to update to the same version but I let it anyway since it started asking. Now of course my android version is 4.2 still and it won't update to 4.2.1 or 4.2.2, I am clicking check for updates but nothing happens, it says it's "up to date" which can't be true...
Not sure what I did wrong, but I would appreciate some guidance, thank you!

In my experiences with other android devices, if you attempt an OTA patch and it fails, the OS which launched the patch (by booting the recovery) has no means to know whether the OTA suceeded or not - it merely assumes that it has... and will no longer offer you a second chance.
If that is the case, only manual updates are possible.
There is possibly a flag somewhere that could be cleared - perhaps via factory reset - that would allow you another go. I don't know where it is, or whether it is reachable on a non-rooted phone without a factory reset.
good luck
PS If you perform it again and get an error, WRITE DOWN THE ERROR MESSAGE.

Thanks but the weird thing is, after it prompted me to update to 4.2 from 4.2 and I did it, it was successful. It's why I find it odd
I do have to mention that I have the Nexus 7 32 GB 3G Version if that's any help to anyone..
So I did this : http://www.reddit.com/r/Nexus7/comments/18hp5p/tip_for_anyone_who_hasnt_gotten_the_422_update_yet/
And now my device is updated to 4.2.2 , how odd

Well, there you go - that's where the state data is located - good find! As to the why of the original failure, one speculation is an incomplete download. In contrast with cwm/twrp, the stock recovery does a crypto signing check over the whole archive. If it was a couple bytes short, it might unpack correctly, but it won't pass the signing check.
If you had made note of the error, you wouldn't be saying "how odd"; you would be saying "here's the exact error that occurred to me".
Glad things worked out - thanks for posting that link.
It has been less than 12 hours since this was discovered (thanks to @rb11701) but potentially big news to those with 3rd gen devices that will not be receiving FireOS v5.
It appears FireOS v4.5.5.1 can be directly rooted with Kingroot! This greatly simplifies the process of obtaining root for those running FireOS > 4.5.2. Simply allow the device to update to 4.5.5.1 via normal OTA and then root.
There are early reports that Safestrap v4 and GAaps (Play Store) also work on 4.5.5.1. More testing is needed, especially wrt Safestrap. I strongly recommend against installing one of the Safestrap compatible custom roms until further testing has been done.
One thing you should immediately do after rooting 4.5.5.1 is block over-the-air (OTA) updates in the event a successor to 4.5.5.1 removes root and closes the vulnerability that Kingroot exploits. Instructions here.
Please note these are early reports. It may not work with all devices. There may be hidden 'gotchas'. All your hair might fall out. Amazon may have installed secret trackers in 4.5.5.1 that transmit your whereabouts to their secret base on Mars (built by Curiosity in cooperation with NASA) before bricking your device. Go in with eyes open.
yes.... THANKS! seems to be working...
where can i found the gaaps? is there i download-package with the latest gapps?

Well - you took your device into uncharted territory and may have paid the price. Safestrap v4 is not a true recovery environment. It was developed with one purpose in mind: host a small subset of roms on FireOS v4 that otherwise could not be installed.
Flashing (injecting) GApps into FireOS with Safestrap v4 is untested and therefore risky. It is also possible there is an unknown incompatibility/conflict between FireOS 4.5.5.1 and GAaps; I think that unlikely, at least one severe enough to keep your device from booting. That said, the presence of Safestrap v4 throws in a wildcard.
The symptoms you describe mirror those following a 'factory reset' from the native recovery menu. If accurate there is no known recovery.
Have you tried to access the device via adb?
i tried factory reset in kindle os menu but nothing happend...
is their a solution to to factory reset with adb?
UPDATE: now i am in a factory reset Loop..... i can select the language... an than kindle tried wifi Connection... than black Screen and select language again... and so on....
Hi,
I tried Kingroot it on my 4th gen HDX 8.9 with FireOS 4.5.5 installed and it worked fine.
Followed these instructions here: http://forum.xda-developers.com/showpost.php?p=59160158&postcount=1 to disable OTA and instalL GApps.
I can install stuff from the play store, use Chrome. So far so good !
Thanks to the rooting gods!

No - but if you can get the device to identify itself via adb there is the (slim) potential for a future solution. It's a shelf item for now; sorry for your loss.

First time I have heard of that approach working! Thanks for sharing.
Do you still have Safestrap v4 installed? It sounds like FireOS may have been 'damaged'. One path would be to reinstall (replace) FireOS with a known good version (4.5.2) but that requires Safestrap. Note - I'm not suggesting you reinstall SS if it is not present as you may end up in the same situation as before. Have to act with caution as your device does not have a true recovery. You need a functioning OS to commence most recovery/repair operations.

Thank you. Suggest holding off on Safestrap and custom roms for now. If you are following the conversation there have been some issues (albeit somewhat unique). Also consider whether FireOS v5 (lollipop based) would be a better long term choice. It's not bad...ran it for several weeks before switching to CM12 on a 5th gen Fire. Too soon to say if other LP options may become available for 4th gen devices.

Count your blessings!
Question: What is your long term goal: FireOS v4 w/Play Store or any ROM that supports the Play Store? If the latter I would give consideration to Nexus v4 or CM-11. Both run under Safestrap v4 and offer a complete android experience with full access to Google Services and applications. Difference between the two boils down to eye candy and a few obscure functions geared toward enthusiasts. I can provide further guidance (if desired) with a better idea of where you want to be.
my first Goal was... Google Playstore... but that dont work correct with this package
http://forum.xda-developers.com/showthread.php?t=2779598
i had a playstore but cant search apps... i press 1 char into the searchbar an app store is closing...
i try to use cm11
ok so Root confirmed for hdx7inch 3rd gen changed kinguser to su, then try to flash the pico zip gapps and got error code insufficient space, and this is the smallest so not sure if everything is working as it should any idea as to why I would have this issue? Thx

adb reboot recovery is not a valid command ; i believe what you meant was

Oops yeah updated to bootloader, hadn't seen the post before or anything on XDA. Been following the normal circles. Can't hurt to spread the news!
The whole reason for suggesting the "optional" part of developer mode is cause if you try just the regular reboot /key press combo and miss it you have to redo the OTA download which is rather annoying. Rather just remove that possibility.

adb reboot recovery is definitely a valid command (assuming you're running a current version of ADB).
Enabling developer mode was not part of my original post, I don't think it is required, but then I was running it anyway. Entering recovery through a command rather than having to catch it at exactly the right moment with the key command is definitely easier, but I hadn't tested it that way when I did this originally. Glad this works too, it's much easier.
Also, glad people are finding this useful!

Ah, now I get it. I forgot you needed usb debugging for adb when booted in system.
Anyways, booting in bootloader mode was easy, it is very hard to miss. One has to press power+volume down immediately after first bootloop, when the screen is back, and i was able to get into bootloader mode within 1 second.

Your right it doesn't work in 8.0. That's why I specified to do it when it says "reboot to update" because when the system "pre-loads" the OTA it switches the active boot slot for next reboot. That's why doing it this way works as well.

No worries! Just glad people are getting updated without needing to factory reset.
(ADB rebot recovery actually does work on 8.0 but you need to have adb debugging enabled and need a new-ish version of the ADB binary).

Oh, yeah, the latest one not only has reboot recovery, but direct reboot to sideload options too....sweet
Btw there is a second workaround. It involves adb sideloading the same build (8.0.0) and then sideloading the Dev preview.
This worked for me. Looked like it was bootlooping again at first, but eventually booted into 8.1.0. Thanks!

Yup, strangely enough, that is the expected behavior for this workaround. @pangolin.rollin should include info about it in the OP post.
What am I missing here? I enrolled in the beta (Verizon locked bl) yesterday and within about an hour I had a notification to update to the beta. I clicked download and install and on the reboot I was running 8.1. What's all this about bootlooping, slots, rebooting bootloader? I did none of that and it worked flawlessly.

Your lucky then! Not sure of the official cause of the errors and why some work and some don't. But seems some devices have issues verifying. That's why Google even pulled ota images.
So I presume that the only problems were with sideloading? I never do that on my Pixel since I just like it updating in the background, reboot and done. With a locked bootloader I can't take a chance of doing something wrong. If they send me an image or OTA that bootloops then it's not my problem and they have to either fix it or replace it. Nonetheless, it's working very well and the reboot wasn't long at all. Might be the better way to go.
I did this fix and although it did work, now when I wake the device back up it takes a long time to do so. Double tapping the screen doesn't work at all, and when I hit the power button it takes about 5 seconds before the screen turns on. I'm going to try to sideload the ota again and see if it fixes it.
EDIT: Nope, still having the same issue

**** While this recovery should not break your device, don't come back here blaming anyone if it does! ****
This is a TWRP 3.2.3 build based on Android 7.1.2 source kernel for the Galaxy Tab Active 2 (codename: gtactive2lte) - Exynos. The "tar" file should be installed using Odin (tested on Odin 3.12.3).
Special Notes:
1. DON'T FORGET TO ENABLE "OEM UNLOCK" (located in Developers options, if its not there, you may have to wait for a few days to access that option, some users claim that its within 10 days before this option appears).
2. KNOX will be tripped once you flashed custom binaries to your phone.
3. Samsung Firmware OTA (aka System Updates) will no longer work once you flashed custom binaries.
(You can flash custom ROMs if you want to keep the OS up-to-date.)
4. It is HIGHLY UNRECOMMENDED to purchase any access to any kind of private forums, ROMs or Kernels.(DO NOT GET FOOLED.)
Installation process:
1. Flash Stock ROM.
2. Flash recovery using Odin (AP = recovery.tar).
3. Load recovery immediately after flashing.
4. Format data (Will erase /data partition).
5. Reboot to recovery.
6. ADB push SuperSU to internal storage / insert SD-Card with SuperSU.zip.
7. Flash SuperSU using TWRP install option.
8. Reboot to system (May bootloop several times. Wait untill system loads).
Bugs:
1. ADB sometimes doesn't work in MTP mode. Need to manually change to PTP in order to get adb usage.
2. Bad label in ADB shell + bad characters appearing while writing through AD. Works well out of recovery and on recovery's terminal.

Please post any bugs you encounter. I will try to fix any issues that come up.
Thanks for the work and sharing. I'm excited to try. Having root would be great, but I'd also like to be able to make voice calls ( using bluetooth as the built-in speaker & microphone aren't adequate ). Do you think this is possible. What changes, if any, are required to have work with T397 Tab Active 2 ( US variant ) ? I'm sure that it's mobile frequencies are different than what the euro-spec'd T395, but otherwise I think identical.

Well, Samsung has a nice repo of their source kernels for every phone Samsung sources
I guess we just have to validate some data taken from boot.img from the stock rom and then build the same with the appropriate source kernel.

Had no idea the source was available for these devices, thanks for sharing. T397 source is in the repository. Let me know if there is something that I can do to assist. I've not compiled these sources although I've compiled other things. Possible to use this tablet as a phone with this ROM as stock T397 ( even after installing several different dialers does not dial ) ?

I can't check the dialer thing, as I don't even have cellular network on my Tablet.
I'll try to build the recovery for the T397 later today, but you will have to check it I guess, as I have no access to that one.

One thing I notice, 7.1.1 is what was/is installed on my tablet now. Not sure what version of Android available on Samsung Opensource or how to check it, but I suspect it is the same since nothing has been pushed OTA.
7.1.1 is what The T397U should have already been on before you started. Mine is and I have not installed this recovery as of yet. Just wanted to let you know it's where it should be.

One thing I notice, 7.1.1 is what was/is installed on my tablet now. Not sure what version of Android available on Samsung Opensource or how to check it, but I suspect it is the same since nothing has been pushed OTA.

Awesome. I really had my doubts being it the first build and all. I guess, there aren't really any major differences.
If it's possible, can you go through the TWRP checklist here
Some of the tests aren't really necessary, but it's a good checklist to go by anyway.
That way, I can officially add it to the OP.

Sorry for delay. I've done the following tests all with the expected results. The only thing I noticed compared to previous installations of TWRP that I've performed ( some years ago ) is that the load time of recovery seems long at 1:15. Also a message about "RECOVERY NOT SEANDROID ENFORCING" which I suspect is normal. Tablet has been working without incident. Thanks again.
Blocking checks
- Correct screen/recovery size
- Working Touch, screen
- Backup to internal/microSD
- Restore from internal/microSD
- reboot to system
-ADB ( yes, if this means being able to access from ADB while in recovery )
Medium checks
- Screen goes off (and on )
- F2FS/EXT4 Support, exFAT/NTFS where supported
- all important partitions listed in mount/backup lists
===> define important ? - depends on the device, i guess
= Assume we can still boot a recovery (aboot/lk is still there for fastboot), can restore everything left ?
- backup/restore to/from external (USB-OTG) storage
- Correct date
Minor checks
- MTP export
- reboot to bootloader
- reboot to recovery
- poweroff
- battery level
- USB mass storage export
- set brightness
- vibrate
Security Policy Updates should not be applied to this system ?
Since this is stock Samsung OS that is rooted I'm guessing this system is still SELinux "enforcing" so does this mean that I can/should say yes to Security Enhancements automatic updates from Samsung ? Any explanation or link on this matter appreciated.
Hey @Shedaim, thanks a lot for this recovery, would it be possible to release an update for oreo?

Hey, sorry for the very late answer.
I'm currently not working on Android and I've never tried on OREO, so my politically correct answer would be: "Right now there is no plan to work the same magic on OREO, but whoever wants, can try to use the device tree I created with a new official OREO kernel (didn't know they have one already)".
Anyway, keep checking the forum from time to time, I may have found the time to work on it
Links to the device tree and other tools used are in the main page of this thread.
Thank you,
Shedaim
I Pay 100$ for making my Galaxy Tab Active 2 booting when its charging
Hey guys,
i hope somebody can help me.
Im trying since 2 Weeks to make my Galaxy Tab Active 2 booting when its charging.
I try all the ways i found (fastboot, LPM change and Autoboot App) and nothing was successful.
So i hope to find with this way somebody who would help me to get the feature.
I need it because i installed the Active 2 on my Harley Davidson as my navigation.
And the problem is that i make a Novalauncher thats looking like the original Harley Davidson one and starts without a code.
So when i put the Tablet in the Mask i dont get a method to press to power button and when i make a method (hole trough the mask or something) then everybody can start up my tablet and use it.
So if somebody can help me with that i will pay them 100$ for helping!
you can contact me at [email protected].
thanks alot

I used the methods and recovery here for my tablet which is a T397U...works flawlessly. The same should work for the wifi T390 you have aswell.
Flash process
I am new to the rooting process. This will be my first time. What is the actual flash process? How do I flash the rom on my tablet?
All the links are dead can anyone please post this recovery

Any hints?
