Installed the latest rc2 release and that restored the original camera icon. This rom does take ages to boot, but it has features that I want that omnirom still lacking, dock battery display. I don't use multi window which the onmirom offering so maybe I will stick to crombi for now. By the way is there much advantages in updating twrp 2.7 to 2.8? How I go about doing so without having to re install the rom, the apps etc...
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
This link shows the changes for TWRP 2.8.﻿

To update to 2.8 you only need to flash TWRP.

Boot into the bootloader and use fastboot.

fastboot flash recovery some-2.8-twrp.img

In my case that would be (openrecovery-twrp-2.8.0.1-flo.img)

fastboot reboot

Nothing more is required.

New TF300 Owner

Good Afternoon,

I recently purchased a TF300, It came with the .17 build software

I used the SparklyRoot apk to obtain root and installed OTA Rootkeeper.

Then I used ASUS unlock device version 7 to unlock booloader.

My question, do I have to upgrade the booloader? and how to do it? which version of TWRP do i flashed?

thank you for your help
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
If you want to remain on the very early firmware you are currently on then do nothing (I don't suggest this).

The TF300T is a very quirky tablet, it can brick very easily.

The bootloader must be matched to rom version used. Twrp must match the bootloader.

If it were my tablet I would remove OTA Rootkeeper and let the tablet update to the latest firmware. This will give you a more stable and recent rom with more features.
[Transformer TF300T Q&A, Help & Troubleshooting] Lento10:
Once it updates, Then I can unlock the bootloader?
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
In your first post you say you unlocked the bootloader.

On this tablet the bootloader remains unlocked unless sent for factory to unbrick or referb.

I updated the software to 4.2.1 no problems, any recomendation on a ROM and Recovery?
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
Roms can be a very personal thing. You may not like my choice and I may not like what you choose. There is room for all.

Ramblin' Man first.

On a new device I tend to go with a stable, smooth rom.

1. I look for an OP that is a recognized developer or a recognized contributor.

2. If the OP bothers to write posts at the beginning then read them all and try to understand what is being presented.

3. My thought is that the first posts by the OP should explain how to prepare your tablet for this ROM and how to flash it. This info would include what bootloader and recovery should be used. On a more forgiving unit this level of detail is not required.

4. Lastly read the last three or four pages of posts for the ROM. If you need help is the thread active or popular enough to provide the level of support you need.

I would probably start with something like this!﻿

I am not assuming you have no experience but this tablet has made many grown men cry. Things are better than they once were. Most ops now tell which bootloader and recovery to use for their rom and that one change has prevented many bricks.

Good Luck!

I did install flatline on my current motherboard but have not found that I needed to use it.

Feeling ready to flash a custom rom

Hi all.

I've had my tf300t for a couple of years and I still love it. It's starting to show its age though and it's getting frustrating to use as it keeps hanging. Even a factory reset hasn't brought the snappiness back. So I think my tablet it telling me that it would like some new firmware.

I'm not a noob to this sort of thing and I currently run a custom rom on my backup phone (htc desire z). I'm just not very confident and want to minimise the chances of me bricking my trusty tablet. So for these reasons I ask for your help and I'd be very grateful of any help you could give.

Firstly I would love an idiots guide to the process of taking an untouched tablet through to a custom rom running beast. I know this information is probably already out these but I'm having trouble finding a good guide.

Secondly I'm open to suggestions on a good rom to install. The important things to me are speed and stability but also that the hdmi out works. After that I'd like the option to overclock and some of the cool multi/floaty window options I've seen. KatKiss looks pretty good but if anyone has a better suggestion then please share.

Lastly if you have any tips or potential pit falls then I'd also love to hear from you.

I'm currently running stock 4.2.1. Thanks for reading!
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
See my post #448 just above yours. Use this as a guide to help choose your rom. You can choose anything you wish. I'll look at your choice and determine if I can help.

The steps needed will partially be determined by your choice of roms. I know where your tablet is now but not where you are going so I can't give steps now.

1. unlock -Unlock_v8.apk﻿﻿

download the above file, install on your tablet, run and follow directions given in the apk

this will unlock your bootloader

[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
Download the three files(rom, gapps, and twrp(download the latest version for the TF300T not the TG)) from the OP links.

Transfer rom and gapps to tablet or download with tablet.

Place twrp into your platform-tools directory.

I always remove my tablet from the dock when flashing.

adb devices this verifies your computer recognizes your tablet if the tablet serial number is shown

If this fails then use this link to install your drivers properly.

http://xdaforums.com/showthread.php?t=2139767

Once you have that sorted open cmd and move to your platform-tools directory.

adb reboot bootloader

fastboot flash recovery openrecovery-twrp-2.8.0.1-tf300t-4.2.blob

after the flash is complete

fastboot reboot

Now you are back in stock rom.

adb reboot recovery

You should now be in twrp.

From main screen select 'Wipe'. At the bottom swipe to 'factory reset'.

Then home -looks like a house.

Select 'Install' select your rom file.

'Add More Zips' and select gapps.

'Swipe to Confirm Flash'

When complete 'wipe Dalvik & Cache'

'Back'

'Reboot System'

Note 1:

This info assumes you are using windows.

If you are using Mac or Linux drivers are not required. Neither recognizes a current path so if you haven't put your platform-tools directory into your path you will need to add ./ prior to each terminal command.

Example:	./adb devices

Note 2:

If your fastboot commands fail but your drivers are good then change your commands as follows.

Example:	fastboot -i 0x0B05 reboot instead of using fastboot reboot

The -i 0x0B05 is needed with some tablets. 0x0B05 is the designation assigned by google to identify the TF300T.
[Transformer TF300T Q&A, Help & Troubleshooting] shanewhittington:
I've got as far as "fastboot flash recovery openrecovery-twrp-2.8.0.1-tf300t-4.2.blob"

It's been going for almost 10 minutes.... how long should this step take? Getting a little worried :/
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
It takes a lot less than that.

Use 'control c' to break the command being sent. Try again with the*-i 0x0B05 in your command.

'fastboot -i0x0B05 flash recovery openrecovery-twrp-2.8.0.1-tf300t-4.2.blob'

If that fails

'fastboot reboot-bootloader' and try again.

I have no idea why but it ust decided to work out of nowhere. It looks like the flashing of the recovery was crashing the tablet it was freezing and the blue bar wasn't filling. Then for no reason it worked and I've now successfully flashed the rom - although I don't think gapps has installed.

I'll keep playing with it. Thanks for your help with this, you've really made this complicate task much more accessible to me.

2. Use fastboot to flash twrp 2.8.

3. Copy ROM to external SD.

4. Boot into recovery (twrp), follow ROM instructions to install.

It could be that I'm just confused because there were lots of older versions that reference individual Android builds (JB vs ICS). And people would say "if you have X version of Android, use Y version of TWRP or you're gonna brick it".

Device not recognized by computer in fastboot mode - how to flash recovery or root?

I am trying for days to get a cutom recovery on my TF300T or at least to get it rooted (which should enable to install a recovery).

The problem is that I can access the device with adb (System: Arch Linux) but when booting into fastboot mode, the device isn't even shown by lsusb so the fastboot command doesn't work (similiar on a Nexus). At both USB 2.0 and USB 3.0 ports. In Addition, the plug (computer part) gets hot and, while connected, the device in fastboot mode seems stuck: animation of the three blinking buttons (rck, android, wipe) is *very* slow, the same with selecting by vol-down.

Does anybody know what is going wrong there?

What could I do to get fastboot working or to root the device?

I tried

flashing by placing zip's on /sdcard/ or microSD (e.g. even the stock ROMs or naming it "EP201_768_SDUPDATE.zip") but when chosing "RCK" in fastboot mode it only says "Error" (red warning sign)

rooting toolkits Motochopper, Framaroot 1.9.3

Nothing worked.

Thank you for any help!

Update:

Miraculously, on another machine (7 years old Laptop) where a Linux did not recognize the device (lsusb)[not sure about that] Windows 8 recognized it and even installed the ASUS driver on its own. After installing Android SDK, fastboot worked (On first try there were errors after each command, but rebooting the device again into fastboot (manually) solved this).

So maybe first try different machines and operating systems before giving up on fastboot.

Anyway, I'm still interested why it should not work on the new Laptop with Linux...

I have a rooted TF300T and runs Kitkat 4.4.4 (kernel 3.1.10) with the official dock, and my my tablet refuse to wake up from sleep mode, but restarts instead. It happens both when docked, not docked, charging, ect...

I hope I am not breaking any rules asking this question, and that someone can help me.
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
I honestly do not know the answer to your question. Most people have moved forward from this tablet so there is not much current information.

I looked in Development and chose the first KitKat 4.4.4, searching for sleep issues there were thirty (some were connected to battery life but others match your situation).

You didn't give the specific rom you have flashed and since there are several KitKat 4.4.4 roms listed there is no place to begin a realistic search.

Begin with searching within the specific thread for the rom you flashed. If you find sleep issues read the post and any follow up. If there are several sleep issues found read posts for several pages beyond each report. If you don't find a fix posted then looking for another rom is probably indicated.

I recently attempted to downgrade from a Katkiss MM rom to a Katkiss LL rom. I followed the instructions for the LL rom install, but it didn't work.

I've flashed various roms for various devices, but I've never actually downgraded before. Does downgrading require a different wipe or process that I'm unaware of?

[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
If you downloaded what I suggested 64x it would need to be installed as a 64bit (program files/system) not 32bit (program files/system32 - is for 32bit files).

I recovered this information from Android SDK | Android Development under system requirements. Did you by chance install the ADT Bundle and was it x86 (32bit)?

I chose 64bit so later you would be on the right path if compiling a kernel or rom was in your future. Google is now reporting 32bit will no longer properly compile roms(this info taken from cm10.1 build site).

I guess it is best to be specific about your sdk download and maybe I can go from there. Sorry this taking so long.

Ok! Just talked to a friend who will be here in a few minutes with a windows laptop for my temporary use.

I'll give this a shot and be back in a few.

First we'll download Android SDK. I know you have just follow and make any changes necessary.

I can't upload my pics so we'll go with words.

go to link Android SDK | Android Developers

Select Download for other Platforms

Scroll to the bottom - SDK Tools Only

Download for windows

Unzip and drag folder android-sdk-windows to your home folder.

click back on your browser

click system requirements

under Other development environments choose JDK 6

scroll down to Java SE 6 Update 43

under jdk select download - scroll down to Java SE Development Kit 6 Update 43 - select windows x64 -when finished run exe and accept all defaults

JDK should now be installed.

open windows explorer in your home directory/android-sdk-windows/ run SDK Manager

put a check beside Android SDK Platform-Tools - uncheck Android 4.2.2 - select install - close when finished

you will find adb and fastboot in the directory /android-sdk-windows/platform-tools

now you need drivers - you can find a link in my signature to install universal naked drivers
[Transformer TF300T Q&A, Help & Troubleshooting] rbellis:
The instructions say to unlock the bookloader. DONE

then to install the SDK tools...I downloaded them. When I install the error (the screenshot I posted) says it to install it to windows/system32/java.exe

My question is...do I creat a folder in system32 and install it there or do I just intall it in the system 32 folder?

So I understand that because I have a 64bit machine that it will need to be in the "system" folder. If I had a 32bit system then it would need to be installed in the "system32."

where do I find "\android-sdk\platform-tools" to place the recovery.img file in?

I'll reply while you sleep. I need to download what you used and install before I can answer.

this would be the default directory - change Casper to your name = C:\Users\Casper\AppData\Local\Android\android-sdk

the guide suggests using C:\tools\android-sdk or C:\android-sdk if you didn't type in one of these directories you will find android-sdk as shown in the default.

If you open cmd as administrator as the guide suggests the terminal will open in c:\Windows\system32 not in your home directory.

I'll assume you took the default location - cd \Users\Casper\AppData\Local\Android\android-sdk\platform-tools

to copy recovery.img select one of the three locations and append \platform-tools - I suspect the default or you probably would remember.

adb and fastboot are located in platform-tools of one of the above paths

I hope this makes sense; I'm having trouble reading it.

[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
You could search for adb or fastboot on your drive. Since the op didn't install in the default location and gave two other choices it obviously doesn't matter, you just need to know where.

I don't know your intent with android but I'll tell one thing I have learned over time.

Directories:

Anything I'm working on for android falls under one common directory and then its own directory.

Example: tobdaryl@reload:~/code/android-sdk-linux/platform-tools$

If I'm working on blobs the directory would be tobdaryl@reload:~/code/blobtools$

Otherwise over time I find I have information everywhere and have resort to search to find my missing directory.

At the moment my code directory looks something like this. I removed several others as the list became to long, but you get the idea.
