I'm having problems Rooting my Nexus One and would be extremely greatful if someone could help me. I got my Nexus One directly shipped to the UK, I am using Windows 7 Ultimate 64bit.
Here's what I've been doing;
I checked 'about' screen and saw it's ERE27 on my N1.
1) I download Superboot for ERE27 - download MD5: 19d302e1bcb18932f009d2a36a3d688f and extracted it to directory (C:\)
2) Turned off phone then plugged in the USB to the N1 (sound on my Windows 7 confirmed the USB connection was made)
3)I I put my N1 in bootloader mode - Turn off the phone then press and hold the trackball to enter the bootloader.
4) I double click 'install-superboot-windows.bat' extracted file on my pc.
BUT then Command Prompt pops up and I get - C:\Users\Bukhtiar\Desktop\1.0-ERE27-nexusone-superboot>fastboot-windows.exe flash boot boot.ERE27.superboot.img
< waiting for device >
After that nothing happens, please could someone help me with a step by step guide as I am new to this.
Many Thanks
You need the USB drivers for the nexus (http://djdoprkngutub.cloudfront.net/usb_driver.zip)
Also, did you unlock the bootloader? You didnt mention it
You need to download the Android SDK and run "Fastboot OEM Unlock"
Do I need to have the phone connected while downloading the Android SDK? Sorry about the Q's but I'm new to all this.
Follow step 1 and 2 in this link
http://androidandme.com/2010/01/hacks/video-how-to-unlock-and-root-a-nexus-one/
then do your superboot step that you have mentioned.
Afterwhich, your phone is unlocked,has a new recovery img, rooted and ready for flashing of custom roms.

I downloaded the Android SDK folder and downloaded the files within it then I followed the links instructions....as follows;
# Reboot phone into fastboot: Power off device and hold down trackball while powering back on. (The fastboot screen is the one with the Androids on skateboards)
# Open a command prompt and navigate to your Android SDK tools folder.
# Type ‘fastboot devices‘ to make sure your phone is recognized.
I opened Command Prompt and navigated to the Android SDK tools folder but I get nothing coming up when I typed ‘fastboot devices‘ nor any message saying my phone is recognized, except in 'Fastboot USB' the phone screen.
This guide is the easiest way to root and unroot your nexus s 4g. If you follow the instructions well you should be fine, included is odin and the files needed if something goes wrong, but it shouldn't as my 11 year old sister could follow them correctly. READ ENTIRE POST BEFORE ASKING QUESTIONS PLEASE.
If your pc doesn't recognize your phone in fastboot make sure your sdk is up to date including thirdparty installs, and download pdanet trial version and those drivers will work. get drivers here http://hotfile.com/dl/92897696/7ae5290/drivers.rar.html
or if your not comfortable installing drivers download pdanet here and install as it will automatically install drivers for you
http://www.junefabrics.com/android/download.php
ROOTING..................
Ok download the files attached and extract them. For the first part for rooting you will need the:
superuser.zip
recovery3101.img
-Ok put the superuser.zip on the sdcard of your phone.
-Power off phone, when off hold volume up and power button to get to bootloader.
-Go the the tools folder of your android sdk and open command prompt and enter the following command: (easiest way is to hold shift and right click on tools folder and hit the button that says "open command window here" then type these command...
fastboot devices (make sure your device shows up, if not your drivers aren't installed)
fastboot oem unlock
-this will unlock the bootloader and you should follow the prompt and accept (volume up, then power button)
-Some have reported unlocking the bootloader erases sdcard..if so when you reboot after unlocking make sure to put superuser.zip back on sdcard.
-this should reboot your phone, now power off, when off hold volume up and then power button to get back to bootloader.
-place the recovery3101.img in the tools folder and type the following command
fastboot flash recovery recovery3101.img
-You should see it say flash ok in the command prompt, now scroll down (on phone) to recovery and hit the power button (ok button)
-Go to flash zip from sdcard and select the superuser.zip and let it flash.
-when done reboot phone, sign into google accnt, download rom manager, open up rom manager go down to All clockworkmod recoverys and flash 3.1.0 (the newest recovery doesn't work for me as my phone can't get into recovery that is why we are flashing the other one )
-All set you can flash other roms, MAKE SURE TO CREATE BACKUP OF YOUR CURRENT STOCK ROOTED ROM FIRST.
UNROOTING.........
Get files http://www.4shared.com/file/N5g8Hav_/root.html?]
-download and extract files, we will be using odin, the 3 tar files.
-extract tar files to desktop along with odin.
-run odin and in the files section select the boxes bootloader, pda, phone.
-click the buttons next to each and direct it to the .tar files we extracted to desktop, so....
click the bootloader box, direct it to sph-d720-bootloader.tar ...then..
click the pda button direct it toward the sph-d720-pda.tar....then..
click the phone button and direct it toward sph-d720-phone.tar....
-now turn off your phone, when off hold volume up and volume down buttons simultaneously, then quickly press the power button....a huge yellow triangle will pop up and say "downloading'.......
plug your phone via usb to computer....odin should automatically see it.....click the start button in odin and let it do its thing and bam...all set.
If you want stock recovery too place the recovery.img in tools folder, open command prompt..type the following command..
fastboot flash recovery recovery.img
Done.
Ill give this a try when I get home....but I'm sure you need to make sure you have all the correct drivers installed...or when you run the fast boo command it won't recognize your phone is connected.
Subbed for when I have time.
Since the NS4G doesn't have a SD Card where do you put the superuser zip?
This will work for the 3g version, correct?

yes it should work for 3g

No problem.
I can't seem to get this to work. I have Win7 64 and I used PDAnet to install the drivers but when I get to the part where I have to type "fastboot oem unlock" the command prompt just says < waiting for device > and there is nothing on the Nexus S 4g other than the normal fastboot options for me to select.

Make sure you installed the right drivers....reboot computer, make sure you opened the command prompt in the tools folder as that is where the fastboot commands are located....also it will automatically reboot in the "unlock bootloader menu" you don't select anything...until that menu comes up..make sure your sdk is updated as well..even third party installs..
I want to thank you, these are great instructions so far. I have been trying for days, got my phone unlocked by a mistake, had to Odin back (came from Epic so know and love that system), but it stayed unlocked.
I cannot get it rooted. Used your instructions and get to second part - cannot install fasboot recovery.
My files are in tools listed as recovery-clockwork-3.1.0.1-crespo4g. I ran fastboot, came up with a large square of instructions, not ok, with command and option. So I tried again. nothing
Then went to phone with it connected, tried to select from card the su file. It goes to yellow triangle and finally get back to a reboot.
I am so close, can you help with what I am doing wrong? It is not rooted and cannot get it to do anything.

Hi all
I have several years experience from rooting and applying all kinds of ROM's om both Symbians, Motorola OS, Android and WM devices but I am completely stuck when trying to "fix" the problem with non-existing SD card support on the Xoom.
What I have been looking for is a guide that walks you through Unlocking, Rooting, adding CWM and finally replaces the kernel with a "better" one. I have of course found all kind of guides on any of the topics above, but all of them assumes that you already have performed one or another of these steps.
So if anyone could be an angel and summarize the steps (links are ok) with the assumption that the reader (I) have
- oem locked
- no cwm installed
- unrooted
- Wifi only
- updated 3.1 honeycomb device.
I will certainly cry of joy if someone can do this for the good of the community. I am sure that many like I have already tried both this and that, and bricked or soft-bricked (I did) their devices while trying to get the god damned sd card to become functional . My own device has now been resurrected from coma (RSD Mode 2) and is now alive again, thanks to "fastboot oem unlock" but I can not for my life get the CWM to work. I have installed the recovery-Tiamat-R4c-100611-1150-cwm.img with fastboot. No errors reported either on the tablet och in Windows during flashing. But when pressing VolUp during boot, I just get stuck in "Starting RSD protocol support 3". I can boot normally if I dont press any button. Fastboot mode works too.
Below is a slightly modified of Land Master's NOOB guide. I have only updated a couple of links. I followed this guide when I originally rooted my Xoom, and it worked perfectly. But note that I have not tested this with the updates. All credit for this goes to Land Master!
USE THIS, AND ASSUME ALL RISKS. IT HAS NOT BEEN TESTED WITH THE UPDATED LINKS!
WIFI ONLY! WIFI ONLY! WIFI ONLY!
If you use this guide, or any other guide for that matter, make sure that you read it, reread it, (10 times!) and fully understand every step. One hour now, spent studying this, will save you 10 hours of headaches later. Make sure you follow every step EXACTLY!
"This tutorial was written for the NooB’s among us (like me) that are new to this stuff and are having a hard time “piecing together” all of the steps. While I am actually a not quite a beginner, NONE of these steps/methods/files have been developed by me. I have simply compiled the procedure in a document that I hope will be useful. With this in mind all the credit belongs to the many individuals that contribute in the XDA Developers forum. I have reviewed many posts by many people and have used all of the information along the way.
A)*Installing ADB
ADB stands for Android Debug Bridge and simplistically stated will be used to send commands to your XOOM using the keyboard on your PC. In essence your PC will be acting like a terminal. ADB is included in a package known as the Android SDK. The following steps should be taken to insure a successful install of the SDK, therefore giving you access to ADB.
1.*Install Java JDK :*http://www.oracle.com/technetwork/ja...ad-346242.html
a.*Download appropriate Java SE Development Kit (JDK) from link above
b.*Double click to Install JDK
c.*Accept Setup Defaults
2.*Install SDK Starter Package:*http://developer.android.com/sdk/index.html
a.*Download SDK Starter Package from link above. There are versions available for Microsoft Windows, Linux and Mac OS X. In case of Windows, both an installer and a zip file are available but there isn’t any need to use the installer as a formal installation is not required. Download the ZIP file.
b.*Once you have downloaded the SDK, simply extract the compressed file to a location on your computer. In our case, we have extracted it to the root of our C drive and that makes*C:\android-sdk-windows*the installation location of the SDK. From here onwards, we shall be referring to this location as the ‘SDK folder’.
3.*Download the SDK Platform Tools using the SDK Mamager.
a.*Browse to the SDK folder and launch SDK Manager.
b.*When launching it for the first time, it will present you with a window to choose packages to install. The first option begins with ‘Android SDK Platform-tools’. Make sure it is checked, and uncheck all the other packages for now. You can check/uncheck a package by simply double clicking on the package. Again, the only package you want to install is the Android SDK Platform-Tools.
c.*Once the process is done, you will have a ‘platform-tools’ folder inside your SDK folder. That folder will include ADB and all its dependencies.
d.*Make a copy of the File “fastboot.exe” which is in the “tools” directory and place it in the “platform-tools” directory.
B)*Install XOOM USB Driver
Just to be sure your XOOM is recognized by your PC it is recommended that you install the latest USB drivers for your system.
1.*Install MotoHelper :*http://www.motorola.com/Support/US-E...arging-Drivers
a.*Download the Driver with MotoHelper from the Link above
b.*Double Click downloaded file and follow on-screen instructions to install.
C)*Unlock Bootloader
Unlocking the bootloader gives you full control over the device so you can flash new Recovery’s, kernels, ROM’s, ETC.*THIS STEP*WILL DELETE ALL DATA AND SETTINGS ON YOUR XOOM.
1.*Put XOOM in Debug mode
a.*On the device, go to home screen, press*Apps*> >Settings>>Applications>>Development, and enable*USB Debugging.
b.*Now connect your XOOM to the PC via USB. New hardware installation should begin and it will start looking for and installing the drivers.
c.*A prompt should appear that states the drivers were installed successfully. On my PC the AutoPlay Device Options also appeared. I clicked “Open Device to View Files” and saw the device Storage with 27.8 GB free of 28.7 GB.
2.*Execute ADB Commands
a.*Open a command prompt by navigating to the ‘SDK Folder’, Holding the shift key, right clicking on the “platform-tools” folder and selecting “Open Command Window Here” from the popup menu.
b.*In the new command window type:*adb reboot bootloader*and press enter.
c.*Wait for the Dual Core screen with “Starting Fastboot protocol support” in the upper left corner to appear and then type:*fastboot oem unlock*in the command window and press enter. You should see: “To continue, follow instructions on the device’s display…”.*
d.*Read the WARNING on you XOOM and either Continue Below or Cancel following the on-screen instructions.
e.*If you decided to continue then on the XOOM Push Volume Down Button to change the selection from “Cancel” to “I accept” and then press the Volume Up to select that choice.
f.*You will be questioned again so Push Volume Down then Volume Up to confirm you want to UNLOCK your device. You will see “Device Unlock operation in progress…” “Formatting UDA”
g.*When the operation completes the device will read”Device unlock operation done – rebooting…” and the device will reboot. The windows new hardware “gong” will sound a couple of times during this procedure. After this step when my XOOM rebooted I also saw an “MTP Device” driver Install dialog box on my PC. Unplug the device, and quickly perform the initial set-up. You can “Skip” any steps that will allow you to (like WiFi setup). Just get back to the home screen and continue below:
h.*Verify that USB debugging is still enabled and if not re-enable it as outlined above.
i.*Re-connect your XOOM to the PC and close any AutoPlay dialog.
D)*Install Custom Recovery
A custom recovery allows you to flash files created by community developers such as ROM’s, Radios, Kernels, Themes, ETC. It also allows you to perform special tasks such as system backup’s, partitioning, cache wiping, ETC. As of 6/19/2011 the generally accepted custom recovery for the XOOM is ClockworkMod Recovery v3.2.2.0
a.*Download Clockwork Mod recovery image (not .zip file) from here:http://forum.xda-developers.com/show....php?t=1074979*
CAUTION: Do not install CWM 4.0.0.X from ROM manager!
b.*Place the File “recovery.img” that you just downloaded in the “platform-tools” directory
c.*In the previously open command window (if you closed it then re-open as described above) type:*adb reboot bootloader*and press enter.
d.*The device will reboot into bootloader mode (as described above) and when this completes type:*fastboot flash recovery recovery.img (name must match name of file)
e.*Check the screen of your XOOM and see: “Flashing StorMgr partition recovery STATUS: - done!*
f.*Type:*fastboot reboot*in the command window and press enter.
g.*Wait 3 second after the Moto logo is seen, then pushed Vol Down
h.* Android recovery menu visible, press Vol Up. Go straight into CWM.
i.*Navigate in ClockworkMod Recovery by using the volume up/down to “move” and the power button to “select”. Look for reboot system, highlight it and hit the power button. Your zoom will reboot normally.
OPTIONAL STEPS
l.*At some time later (AFTER YOU ARE ROOTED) to avoid the need to execute ADB commands to enter recovery, I suggest you look for a free application called “Quick Boot”, by Sirius Applications from the market.*
m.*Once Quick Boot is installed run it and simply select “Recovery” to boot into ClockworkMod.*
Next Step: Following Public Animal's guide to rooting >*http://forum.xda-developers.com/show....php?t=1075260*
Last step (optional) install Tiamat 1.0 ROM >*http://forum.xda-developers.com/show....php?t=1117004
Thanks a lot! I am with you all the way to step H (adb reboot recovery). This step ends with the Android, yellow triangle and an exclamation mark. Nothing more. So something must be wrong with the recovery image.
In both your links and other links to the recovery image, the name "recovery-solarnz-XXXXXX-XXXX.img" is used. But the links always leads to the image "recovery-Tiamat-R4c-100611-1150-cwm.img" instead. Could this be the problem? If so, what should the XXXXX be replaced with (for googling).
Thanks again for the guide. Sooner or later I *will* succeed!
Edit: Could this post be something that explains why my CWM flashing does not succeed? http://forum.xda-developers.com/showpost.php?p=13747198&postcount=18
And since the device still not is rooted, I can not rm the suggested files ... gaaah

The name of the file is "recovery-Tiamat-R4c-100611-1150-cwm". So you should type:*fastboot flash recovery recovery-Tiamat-R4c-100611-1150-cwm.img
It actually worked! What I did was this
1. adb reboot bootloader
2. flashed the same recovery image that I mentioned earlier
3. fastboot reboot
4. applied the 3 second wait once the Moto logo was seen, then pushed Vol Down
5. Android recovery menu visible, press Vol Up. Now I got straight into CWM !!!
6. (prepared the sd card on my SGS with the zip files)
7. Choosed Install zip from sd card and flashed the wifi-root image
8. Reboot the tablet and verified with RomManager that I now had root

For simplicity I renamed the zip to recovery.zip before copying it to the folder and flashing it (see next post also!)
I am going to modify the instructions. Is this correct for what you did?
"f.*Type:*fastboot reboot*in the command window and press enter.
g.*Wait 3 second after the Moto logo is seen, then pushed Vol Down
h.* Android recovery menu visible, press Vol Up. Go straight into CWM.
j.*When my device rebooted into recovery I also saw additional Device Drivers install. This took a little while and I waited to do anything until I received the “Device Driver Installed Successfully” dialog."

Yes, everything except the last step (j). I did not see anything on the computer screen. But now I have managed to install CWM, root it and install Tiamat 's latest kernel. The external sd card is now visible inside /sdcard/external! Success!

This is an amazing guide! cam30era you and LandMaster are the bomb!
May suggest one thing? When reading it through, I think a real noob might be confused with the asterisks that are on either side of many of the adb commands.
Anyway this should definitely be a sticky!
actually I sat down and wrote my own guide, starting from scratch and ensuring that every assumption and requirement was explained. I called it "idiots guide to ..." . Maybe it would be a good idea to consolidate the best from both guides into a -definitive guide-. What do you think?
Oh, the thread is in the Android development forum. Mod is welcome to move it if so needed

CWM won't boot.
For the life of me I can't understand what I'm doing wrong. US Wifi Xoom with 3.1, bootloader is unlocked, but not rooted. I use fastboot to flash the latest recovery img, 3.2.0 I beleive. Says it's successful, but like many on here when I either use "adb reboot bootloader" or if I time it and press volume down to get into the recovery, I only get a picture of the robot with the triangle. I can press volume up+power and I get the stock recovery.
I've read every post I can read but most people who have resolved the same issue were just not flashing the correct image. Which I'm sure I'm doing correctly.
Amy help would be appreciated.

Hehe, no disrespect but since the bookshelves are drenched in "for dummies" and "for idiots", I thought it might be ok to use that title. Glad that you finally succeeded!
Hi everyone,
I'm owning A TF300TG model and I recently tried to flash one of the ROMS referrenced on those forums and by doing so I found out that my tablet had lost the 3G features so I had to flash back the Asus stock ROM to get it back.
Since I saw many of you got trouble reinstalling the stock ROM, I decided to write a quick guide on how to do it so everyone could get their tablet fully working again
Note: For the record, when I did the following operations, I already had unlocked the bootloader and installed the CWM recovery.
Disclaimer:
By following this guide, you will have to issue commands that risk to damage (aka. brick) your tablet or at least void your warranty. I won't be responsible for any damage made to your device. You've been warned.

Download the stock ROM zip file on Asus website (current version is [WW | TW]_epaduser9_4_4_28_1UpdateLauncher.zip) for the TF300TG tablet. Be sure to download the firmware matching your SKU.
Unzip the downloaded file, you will get another archive called , unzip this one too
You should end up with several file, with one of them called blob
For the next step, you will need to install the Android SDK to get the fastboot utility. If you do not know how to use fastboot, you should take a look at this guide.
Once you have installed fastboot, boot your tablet into fastboot mode (Plugin your tablet on your computer's USB, Hold down Power+VolDown, dont press VolUp when prompted, select the USB icon and press VolUp)
Open a command line terminal and navigate to the folder containing the blob file.
Then type the following command:
fastboot -i 0x0B05 flash system blob
Click to expand...
Click to collapse
For some reason, the transfer seems to fail from time to time, if so, just try again by going back to previous step.
Once the transfer is done and you get that sweet "SUCCESS" printed on your screen, just type the following command to reboot your tablet:
fastboot -i 0x0B05 reboot
Click to expand...
Click to collapse
And there you have ! You are now back to stock ROM with fully working 3G
Thanks a lot for this, I found these instructions on Wolf's thread but wasnt sure it would work with our devices, Thanks for taking the first big step.
Questions.
1. Does this wipe your data?
2. Does CWM still work after?
AFAIK, this will wipe your data, remove CWM and uninstall root. Your device's bootloader will still stay unlocked though.
You will have to flash CWM back using this guide: http://forum.xda-developers.com/showthread.php?t=1668173
Hi, followed the steps but it didnt work for me
Fastboot copies the file but after when it tries to flash it gives an error
sending 'system' (796653 KB)...
OKAY [137.443s]
writing 'system'...
FAILED (remote: ()
finished. total time: 138.477s
The Tab shows
Failed to process command flash:system error(0x170003)
The progress bar is showing under the USB logo with 1% blue, after hold power down I'm back into Onyx Rom
Any Thoughts?
I had the same problem and I just issued the same command a second time and it worked just fine
Try to format your /system (under the mounts and storage option) from CWM and wipe data and cache.
2nd time a charm!
Worked fine the second time i ran the command,
Im back to stock again :good:
I will wait for a 3G friendly Rom before flashing again
Thanks for your help

Thanks a million. This worked for me as well after 2 tries. Saved my $400!
Thanks heaps for this
I ended up in trouble when I flashed the TF300T firmware by mistake. It kept freezing and rebooting on me after that little stuff up.
Anyhow before I did that I made a backup with CWM, and after I restored it my 3G was gone but everything else worked fine.
Manual updates were failed though and they still do. At least I have my 3G back :victory:
So this method would probably work for upgrading to .40 as well, but it means a complete datawipe!
I'm sure there are many of us in the same boat now. I guess we will just have to wait and hope that some kind person makes a recovery image for the TF300TG?

Hi, any idea why i dont have this 'USB icon' ?? i have 'wipe data' and an android icon that performs a cold boot.
Any idea why this will seemingly flash fine, but go to bootloop when I fastboot -i 0x0b05 reboot the tab?

Using
fastboot -i 0x0B05 flash system blob
Click to expand...
Click to collapse
is a tad wrong. It works, but only by accident.
You should be using
fastboot -i 0x0B05 flash staging blob
Click to expand...
Click to collapse
The technical reason for why your command works, is because the nvidia bootloader writes files to the staging area before writing it to the partition you specify.
What essentially happens is:
Blob is written to staging
Blob is copied to system (meaning non-booting system)
On reboot, blob is "extracted" from staging and properly flashed.
Step 3 is what makes it work in the end, but you are causing an extra unneeded write to the flash (step 2 is not really needed) (In this case it works, but it potentially increases the risk of bricking)
thx didn´t know that. So all the howto´s are wrong

Your probably running Jellybean, if so this HOWTO does'nt work.
Question: What exactly is supposed to happen? First I tried it and got the fail and did it a second time and it seemingly worked. In my command prompt it ended with
"writing 'system' ... OKAY"
and wasn't doing anything after that in the command prompt and on the tablet there was a full status bar so it looked like whatever it was doing it was finished? So I held the power button and I think it was a boot loop ... it just was the ASUS screen with the spinning circle. So I just did it again, failed the first time did it again and now I am where I left off. I guess I will wait a while and see if it says "SUCCESS" on my tablet? And if not I will put in the reboot command? (I probably should have tried that last time instead of holding the power button I forgot about the last couple lines of the guide )
EDIT: Or is it cuz I am flashing the wrong SKU? I didn't know what one my tablet is supposed to be ... its a cyanogenmod build so I don't think I cant find what the SKU is supposed to be. I went with US SKU because I live in the United States but I don't know if that's what it is
EDIT2: After waiting a while with no "SUCCESS" Windows said that adb.exe crashed or something. So I put in the reboot command but now it seems to be stuck on the ASUS loading screen again.

I have a WW TF300T and had no problem flashing a US version.. so its no SKU problem how long did you wait on the ASUS screen with the spinning circle? It took up to 5 mins for me! just wait a lil bit longer next time.. And there comes no "SUCCESS" on the tablet! only a blue bar that should be full after SUCCESS comes up in your Fastboot-COMMANDLINE.. the reboot with the fastboot reboot command from the first page..just give your tab a bit more time.. its like a babe. handle it with care :silly:
Success!
Hazaa! I can confirm that I managed to flash back to stock by flashing the blob to the staging partition. Like so many other, the first flash failed but the second time worked. I now have working 3G again!

Thanks for the reply 0nyx7!
I had waited a while, maybe 10-20 minutes? But I don't remember entirely. I tried flashing the stock firmware a few times but eventually I just gave up. I didn't like the possibility that my tablet was bricked so I just aborted mission and decided to go back to cm10 where it was safe. I just looked up a post on how to flash Clockworkmod Recovery with fasboot and then flashed a cm10 nightly I already had on my internal storage. So all is good... Mostly.
I have been asked to port my "Beginners Guide" from the TF700 forum for the TF300. Since both tablets are very similar, that was not too hard to do
If I have missed to update a link specific for the TF300, do let me know please.
And the standard disclaimer: I am not responsible if you misunderstand instructions I give here, if my instructions are wrong, if you forget to charge the battery and the tablet dies halfway through a flash or if your house goes up in flames. YOU DO THIS AT YOUR OWN RISK
These instructions assume that you are on the latest Asus bootloader: 10.6.1.27.5
To determine which bootloader you currently have:
From an "Off" state, boot the tablet with Volume Down and Power into the bootloader menu. Read the small script in the upper left. You'll see
US_epad-10.6.1.27.5-20130801" or similar.
US or WW, JP, CN is your SKU or region
10.6.1.27.5 is your bootloader version
20130801 is the build date (and immaterial in most cases).
First things first:
Backup everything on your tablet you care about to an external microSD or your PC. Don't worry about your apps. You can always install them from the Play Store.
This is just common sense. It is not inherently risky to flash custom ROMs. But something can wrong at any time and you have to be careful. If you are, this is a safe procedure.
Basically the process of flashing a custom ROM on the TF300 involves three steps:
1) Unlock the bootloader using Asus' Unlock tool
2) Install a custom recovery on the tablet
3) Flash a custom ROM of your choice using said custom recovery
Unlocking the bootloader
Your tablet should be fully charged at this point!
Make sure "USB debugging" is checked in Settings > Developer Options (if you don't see it, go to About Tablet and tap 7 times on Build Number)
Go to Asus website: https://www.asus.com/support/Download/28/1/0/9/8BmzkQ4yoz5WzBrW/32/
Choose "Android" for OS and look for the "Utilities" on the resulting page.
Download the Asus Unlock Tool v7 (not v8! It says v7 is for ICS but it'll work fine on JB - see below)
The tool downloads as a .rar file which is an archive you have to decompress. 7zip is a free and very good Windows tool that will do it for you
On your tablet, in Settings > Security check "Unknown Sources"
Copy the .apk you extracted from the .rar archive to your tablet.
Find the apk in your tablet's file browser, tap it and let it install
Open the app and follow the instructions. You will loose your warranty as soon as you click "I agree".
Update 2/15: Google added another wrinkle: It now checks even sideloaded apps and refuses to install them if they are considered not secure. The Unlock tool seems to fail their test. v8 does not install at all anymore. v7 will install if you allow "less secure apps" in your Google account settings. On the web - not your Google account on the tablet
July 2015: And another wrinkel... It seems to be pretty consistent now that the Unlock Tool hangs on the Google account password step. I suspect something changed on the Google side. It probably doesn't allow the tool to check/compare the password anymore. There have been quite a few security changes lately and the unlock tool never gets updated so I suspect that Google now is blocking access by the tool to it's servers.
The work-around is easy enough: Delete the Google account from the tablet (Settings > Accounts), then run the tool again. If that doesn't do it, do a factory reset from Settings, reboot and during the initial setup establish a WiFi connection but skip the google account setup, then run the tool

This can be a 5 Minute operation that goes without a hitch or a very frustrating experience with lots of error messages. There is no definite rhyme or reason for this. For some people it works like a charm, for others it works after 15, 25 or 55 attempts, for some never.... This problem is widely discussed on several forums. Google it if you hit that roadblock.
To check if you are unlocked, boot the tablet and read the tiny script. It should say:
The device is unlocked.
Installing a custom recovery on your tablet
I highly recommend you choose TWRP as your custom recovery. If you want CWM, you are on your own.
To push TWRP to your tablet you need to set up "Fastboot" between your tablet and your PC. Fastboot is a protocol that enables you low level access to your tablet.
Practice/Background
Power down your tablet and disconnect it from the dock
Push and hold the Volume Down key (left side of the rocker) and the Power key until you feel the tablet vibrate twice. Let go when you see the tiny script. Read it and it tells you that your tablet is now in fastboot mode and you will see three icons (I assume again you are on a JB 4.2 bootloader. In older bootloaders you had 4 icons and had to select the USB icon to get into fastboot mode):
RCK - (which should be flashing) is your recovery (the stock recovery at this point, but once TWRP is installed this is one way to get into it)
Android - is your system, selecting it boots you back to into your ROM.
Wipe Data - stay away! Especially with custom software installed never, ever use this option!
To toggle between the three icons use Volume Down, to select one use Volume Up. Try it but do not push Volume Up when the 'Wipe data' icon is flashing!
Installing ADB and fastboot plus the necessary drivers
For a working ADB/fastboot connection from PC to tablet you need:
a) Asus device drivers – if you connect the tablet to your PC and it's recognized as a portable device you should be ok. If not, download the Asus Sync Utility from their support/downloads site and install it to get the drivers, then uninstall the program from your PC if you don't want it. The drivers will stay.
b) Fastboot and ADB drivers which will be installed if you run the tool below.
Windows Vista, 7, 8, 10:
Download and run this cool little tool [TOOL] [WINDOWS] ADB, Fastboot and Drivers - 15 seconds ADB Installer v1.1 - xda-developers (don't forget to hit the Thanks button)
The tool installs the adb and fastboot.exe to a folder on your C:\ drive (look for adb) and the corresponding drivers. Takes about 15 seconds.
On Windows 8 and 10 you need to turn off the driver verification feature. Here's a great video on how to do it:
https://www.youtube.com/watch?v=afrvSGiMAtk
Or - even better - here's a quick command line toggle to achieve the same (thank you @Jack_Hardin):
Jack_Hardin said:
If you're running W10, you can disable Device Driver Signing without following the procedure in the linked video, but by (more simply) right-clicking on the Start button, selecting Command Prompt (Admin) and then typing:
Code:
BCDEDIT /set nointegritychecks ON
Doing the same with OFF at the end of the string, as easy to guess as it looks, will reenable them.

I recommend the "ADB Install Tool" mentioned above or the 'Minimal ADB Fastboot Tool': [TOOL]Minimal ADB and Fastboot [7-18-13] - xda-developers
Either works fine.

Win7 and Win8 users seem to have the best luck wth the drivers sbdags provided here: http://forum.xda-developers.com/showthread.php?t=2646279
It's fine if you want to use his Recovery Install Tool from that thread. But I highly recommend you familiarize yourself with basic fastboot commands! There are lots of tuturials all over the web.

http://htc-one.wonderhowto.com/how-...-mac-os-x-send-commands-your-htc-one-0151178/
The fun begins
Fastboot does not play well with USB 3.0, so use a USB 2.0 port for this. And no hubs and such....
Boot the tablet into fastboot mode and connect it to your computer via the original USB cable
In Windows Explorer navigate to the folder that contains your adb.exe and fastboot.exe
Win 7/8: Shift + right click and select "Open command window here".
For Win XP click here
select 'Run' from the Start menu, type
Code:
cmd
and hit Enter. In the resulting command prompt type
Code:
cd C:\adb\ [I](or whatever the path to your fastboot folder is..)[/I]
In the command window on your PC type:
Code:
fastboot devices
If that command returns a string of numbers and letters, you are good as gold.
Click me: View attachment 3070087
If it returns: "No devices found", fastboot is not working - yet - and you have to troubleshoot.
Getting the correct drivers working can be the hardest part of this exercise. If your computer does not "see" the tablet in fastboot, try to uninstall the existing driver (if any) in Device Manager and manually install the drivers I linked to above. And if Windows does not cooperate at all, PM me and I can hook you up with a Puppy Linux live CD with fastboot/adb set up already.
Let's assume everything is good:
On your computer go here: https://dl.twrp.me/tf300t/
Download the latest version of TWRP.
FYI ONLY: If, for whatever reason, you want to format your data partition:
Formatting /data starting with TWRP 2.7.x and later takes a lot longer than in previous versions (up to 90 minutes). LET IT FINISH. DO NOT INTERRUPT THE FORMATTING.
Rename the file to twrp.blob and place it into the same directory as your fastboot.exe. Note: More recent versions of TWRP download with an .img extension. Leave the extensions as is, rename the first part to watever is easy to type
Again check the connection with
Code:
fastboot devices
If you get the connection, in the command window type:
Code:
fastboot -i 0x0B05 flash recovery twrp.blob
or
Code:
fastboot -i 0x0B05 flash recovery twrp.img
This will flash the recovery to the recovery partition
If it is successful type:
Code:
fastboot reboot
and let the tablet boot up normally.
You may get a dialog in TWRP offering to root the stock rom. You can accept or cancel it - doesn't matter. I assume you are going to install a custom rom and they are rooted anyway.
Create a nandroid
Your almost there! You are now on the stock ROM with a custom recovery installed.
Power the tablet down and boot into the bootloader menu with Volume Down and Power buttons.
With RCK flashing, push Volume Up and you should boot into TWRP. Familiarize yourself with the many options of the touch based interface without executing anything yet. TWRP is very user friendly. You basically cannot do anything of consequence "by accident", so don't be shy.
To create your Nandroid (a full system backup) touch "Backup", leave the default selection as they are and swipe the button to create a nandroid of your current system.
This is a very healthy habit to develop: You always want to have a nandroid of your last working system squared away so that you can do a simple restore if you flash something that does not work, or something goes wrong during a flash. With a working recovery and a good nandroid you are minutes away from a working system if you soft brick your tablet.
Hint:
It's a good idea to have at least one good nandroid on external media. Sooner or later you will format your data partition and if you're like me, you may forget to backup your nandroids in the heat of the moment..
Installing a custom ROM
From here on out it's as easy as downloading the installation file of your custom ROM, booting into TWRP, choosing "Install" and navigating to the zip of the ROM you want to flash.
If you see a "signed" in the zip file name (best_rom_ever_signed.zip), make sure you check "verify zip signature" under the "Install" menu. Some devs sign their ROM zips - a better way to ensure file integrity than md5 sum.
Whatever you decide to flash: READ THE OP of the corresponding thread and make sure you have the correct bootloader and the required recovery installed! I can't stress this enough! If you are not sure, DO NOT FLASH!
Look for the ROMs in the Development section of the XDA forum for this tablet: http://forum.xda-developers.com/transformer-tf300t/development
It is mandatory to do a Factory Wipe in TWRP before installing a custom ROM or going from one ROM base to another (a so called clean install).
If you choose 'Wipe' in TWRP, all you have to do is swipe the button - 'Factory Wipe' is the default selection under the 'Wipe' menu. You will loose your apps, but it will not wipe your /data/media/ folder where your files, pictures, etc live.
If you do this right before flashing the custom ROM, make sure you have the zip file of your custom ROM on your microSD - not on your internal SD where it may get wiped....
Once you installed a custom recovery NEVER EVER UNDER ANY CIRCUMSTANCES - AND I REPEAT: NEVER! - use the 'Wipe Data' option from the bootloader menu or the "Factory Reset" option in Settings > Backup&Restore.
In your custom recovery you have the option to wipe, backup and restore every partition on your tablet selectively or collectively. Any wiping, any backup and any restore of the system, data, recovery or boot partitions MUST be done in your recovery (or in fastboot)!
You can safely use Titanium Backup or Asus Backup for apps and settings, but that's it. For everything else use your recovery.
FREE ADVICE
There are alternative methods to flash a recovery to your device using apps like GooManager (currently not supported anyway), TWRP Manager or Flashify from the Play Store which do it right from your tablet. These apps "save you the trouble" of getting ADB and fastboot set up and working on your PC. These methods still exist and they do work - mostly - and if you have root. But I would not recommend them.
If you are not willing to invest the time to learn the basics about ADB and fastboot (google "adb fastboot xda tutorial") and install the necessary drivers on your PC, you should not be flashing anything to your tablet!
GET ADB AND FASTBOOT WORKING!
Sooner or later you will do something stupid (I have done it and so will you) and ADB/fastboot may save your bacon IF you had it working when you didn't really need it.

boot sequence
Hi,
Is normal to see three TUX and some phrases at the power on ?
Can I hide it ?
tnkx
Nicola
You mean the penguins?
That's normal I'd you're running a Rom that uses _that's preinit scripts. You can't hide them - why would you?
thank you SO much
I love you!
Wow, I've never had so much trouble rooting a device before! And days ago, I rooted my T700 without any problems. So, I guess I should have expected the hubby's TF300T to be problematic! Recoveries didn't work, I tried multiple ones. Eventually, I had a recovery that didn't recognize any partitions. I used fastboot to erase them all and put the stock ROM back on--wouldn't boot up. This thread was an immense help! I've moved the other recoveries and ROMs into my non-working folder!
Thanks again!
Lynne
Awesome
What a well written guide! I have a decent understanding of fastboot and adb (although minimal experience), and I perfectly understood every step.
My advice to all newbies like me.... Read stuff ALL of the way through (and understand it), BEFORE stepping off in it.
ok im a bit lost... i have rooted both Nexus 7s, nook hd and hd+, a tf101, and a few tv boxes.. so im not sure why this is hanging up... im trying to root and install the TWRP recovery on a tf300... followed the instructions and even have the char string that means... every thing should be good to go.... have checked that the twrp is in the dir of adb... but when i try to push the twrp.blob to the tf300, it just give me.. this error..
c:\adb>fastboot devices
015d14febf64041b fastboot
c:\adb>fastboot -i 0x0B05 flash recovery twrp.blob
sending 'recovery' (6800 KB)...
FAILED (command write failed (Invalid argument))
finished. total time: 0.002s
so.. at this point i not sure what else to trouble shoot... the tablet is in fastboot mode.. adb sees the tablet.. at least that is what the char string confirms.... so any help would be very much appreciated.. just a bit lost on this...

The bootloader is unlocked yes ?
What is your bootloader version ?
Try a different USB port ?
Thx Josh

thanks again.!
Nice guide!
I've been wanting to put a custom rom on my transformer for a long time. This guide worked like a charm.
The only problem I had was when I tried to flash TWRP recovery, but switching USB port fixed that problem.
I flashed the latest CM12.1 nightly and it works fine.
Many thanks!
Help please, I'm stuck!
I'm trying to flash recovery,
after typing:
fastboot -i 0x0B05 flash recovery twrp.blob
I got this on tablet screen:
"Starting Fastboot USB download protocol"
for about 25-30 already and nothing happens, any ideas?
thanks
You won't see anything on the tablet screen, but what does the command window say?
Go back, read the guide again, it's all in there....

The command window didn't say anything, just blinking cursor after my command line

Thanks,
After writing the question, I've restarted my tablet and did all the steps again.
The second time everything worked as it should. :good:
thanks for your great guide
Really great guide
Amazing guide thanks for the help
Thank you for this good tutorial but I have one question.
I'm a newbie here, here is my dilemma: I've flashed CM android 5.1.1 successfully from stock 4.2. (Thanks for this detailed tutorial), but I lost my root privileges, now I can't use my root apps. How do I apply root to this ROM? My device is an ASUS TF300T. I've tried Kingo Root and King Root but no success.
I would really appreciate your help and inputs.
Cheers!

I have not used CM in quite a while but I think you have to enable root in Developer Options. I think it is not enabled by default.
If hat does not work you can go to Chainfire's website and download the flashable SuperSU and just flash it in recovery
Thanks and a couple of notes on TF300T
Thanks so much for the great guide. My 300TF was nearly bricked due to slowness and freeze-ups. I'd stopped using it. The process worked and am now running KatKiss. Couple of problems and their solutions for anyone who may have the 300TF:
-When trying to "Unlock Bootloader" I kept getting to "enter Google password" but when I did so (correctly) it was not accepted. The solution was to do another factory reset and NOT install google services. Didn't ask for password after that.
-Used fastboot command line to install "twrp.blob" but nothing happened and it timed out. I had to take out other usb connect programs first (in my case "easy-tether" and my LG phone connect app.) After that everything went as per your guide.
Thanks again
