[Q] Do I still need a special fastboot.exe for TF300T? - Transformer TF300T Q&A, Help & Troubleshooting

I have 3 HTC devices and 2 TF300T's. I have all the drivers for HTC's devices and TF300T
along with the SDK tools for ICS and JB. The two SDK directories are in my Win 7 Pro x64
PATH so I can run them from any cmd.exe window. I remember seeing a special
version of fastboot for the ASUS tablets and wondered if that was needed for
use of fastboot mode on the TF300T?
If I do, can someone past a download URL for it?
Thanks

The fastboot.exe is the same for all android devices.

Funny thing happening to me: fastboot devives doens't return serial no. but it does work when I flash ...

If you have got a problem with your adb or fastboot or recovery....it's very simply and faster
use this:
Download this file "fastboot.zip"
Install this file somewhere in one folder which is named "fastboot" on your PC
=> disk C: root
Unzipped this file on the folder "fastboot" and you will find 3 files:
- adb.exe
- AdbWinApi.dll
- fastboot.exe
and when you need to push something by the bootloader, you can use it.
Don't forget to push on this folder the file that you need. For exemple: boot.img or a recovery.img, etc...
The line command is :
Code:
c:\fastboot>
Enter
Code:
c:\fastboot>fastboot flash recovery recovery.img
Enter
If you want to flash the "recovery.img" file

[Q] Problem flashing recovery.

Hi guys.
I have been trying to root my HTC One S for hours now without any luck.
I have been using this guide,(http://forum.xda-developers.com/showthread.php?t=1583427) and have managed to get all the way to the last step in the "recovery"-section.
But when I try to flash the recovery, this is what I get:
c:\fastboot>fastboot recovery clockwork-touch.img

How can this be?
Thanks in advance for your help
Type the following command
c:\fastboot>fastboot recovery recovery clockwork-touch.img
Thanks for your reply, frazzeld.
It didn't work. Sorry. Still the same text coming up.
Maybe there is something wrong with have a managed my fastboot-folder.
Because I am a new member I cant post a picture of my folder :/
But it is set up like this:
(folder)add-ons
(Folder)platforms
Folder)tools
adb
adbWinapi.dll
AVD Manager
clockwork-touch.img
fastboot.exe
SDK Manager
SDK Readme
Unlock-code
Never mind.
It worked after all. Don't know what I did wrong the first 50 times.
Thank you
which clockwork are you trying to install?
Edit: I see you've sorted it now
Are you in fastboot mode? Also the recovery image has to be in the same folder as fastboot.exe is.
To point to the correct folder its "cd"
e.g.
cd c:\fastboot
And the correct command is;
fastboot flash recovery name_of_the_recovery.img
Thats all i can see from what you've posted
edit: too slowwww, glad you got it sorted

From the proper directory. It's not C:\ for everyone... Some have their fastboot.exe in C:\Android and some even C:\Android\platform-tools for example.
Point being, make sure u know where your fastboot.exe is located

Semi-bricked sensation (corrupt IMEI?)

Just over half a year ago (January 2012) I have unlocked my sensation with rev. h-boot, installed 4 ext recovery and flashed Android Revolution. I've been using the phone in a number of countries since, with no problems. A couple of days (9/08) back, when I returned to the UK my sensation started behaving as if it had been IMEI blocked, and after fiddling around for a while I discovered that the IMEI android reports is different that the one printed under the battery/on the box. Given it doesn't seem I have any backup (bear in mind it worked like a charm for past half a year) is there any way of repairing that corrupt IMEI? Is it (so naive) stored in more than one place on the phone so I could access the factory IMEI or anything of that sort? I've tried using the fastboot oem writeimei command, as well as the root terminal emulator command that have been posted on these forums a number of times but neither of them worked.

From the dialler which one does *#06# report ?
Your fastboot might be neutered (can't issue write commands properly) if you upgraded the HBOOT using the universal firmware packages posted in the Dev section, even though it is still s-off.
When you boot into the bootloader, does it say *** LOCKED *** or Revolutionary in the very top left? If it's *** LOCKED ***, you need to reinstall the Revolutionary HBOOT.
If it says Revolutionary, issue the following commands from Windows to fix your IMEI:
Code:
fastboot getvar imei
[shows old imei]
fastboot oem writeimei 123456789012345
fastboot reboot-bootloader
fastboot getvar imei
[shows new imei]

It needs a custom fastboot binary (Revolutionary) and you are (technically) legally limited to restoring a damaged IMEI on your own consent. As explained, creating a false IMEI is illegal. Just a heads-up.

Fastboot Driver

I am trying to put a ROM on the TF300. I have Unlocked the tablet and installed the ADB driver. When I boot into recovery and the USB icon it asks for a driver for fastboot. I can't seem to get that anywhere. I have the Android SDK installed and java etc. Where is the driver located? I look in the USB driver folder but its not in their...

Here is the info.
Normal power up : It simply reboots your device.
Recovery : takes you to recovery menu of your device. From here you can flash any ROM, backup or restore your device, factory reset or do any other kind of tweak.
Factory : Deletes all the user data. (I.e. all your apps)
Switch console : I don't know what it does.
Barcodes and BP tools just provide you with some info of your device.

[GUIDE][BRICKED] [BOOTS ONLY TO RECOVERY][All ASUS TRANFORMERS]

This is a general users guide to unbrick your Transformer tablet.
This guide will help you if your Asus tablet will only boot into recovery
and the command
Code:
adb reboot-bootloader
does not work to get you booted back to bootloader screen ..
If the above command works then skip to the first fastboot command ..
WHAT YOU NEED
An Asus tablet that will only boot into recovery …
Woking adb and fastboot on your PC
Windows drivers (if using Windows)
A fully charged tablet
Asus data cable
Stock firmware blob (from Asus's web site, make sure you get the right one)
_that's bootit.ko (unzipped and placed with fastboot.exe)
Downloads
Asus Stock firmware---MAKE SURE YOU GET THE CORRECT SKU FOR YOUR TRANSFORMER TABLET
click me
_that's bootit.ko----click me
INSTRUCTIONS
Extract your stock firmware in your downloads folder twice...You will see a blob file rename it boot.blob and move it to the same folder as your fastboot.exe or if in linux to your home folder
Unzip the bootit.ko and place it wth the above blob file.
Let start with this command to make sure that your PC can see your table as an ADB device in recovery
Code:
adb devices
OUTPUT
Code:
[email protected] ~ $ adb devices
List of devices attached
015c7d7a445c260c recovery
Then lets push the bootit.ko to the root of the device like this
Code:
adb push bootit.ko /
OUTPUT
Code:
[email protected] ~ $ adb push bootit.ko /
673 KB/s (27690 bytes in 0.040s)
Then lets insmod this .ko file
Code:
adb shell insmod /bootit.ko
This should reboot the tablet into the bootloader menu, lets verifiy.
Once in the bootloader screen lets make sure your PC can see the device in fastboot.
Code:
fastboot devices
OUTPUT
Code:
[email protected] ~ $ fastboot devices
015c7d7a445c260c fastboot
So now its time to erase the misc & cache partitions, as that is most likely the partitions that is making it boot to recovery...
Code:
fastboot erase misc
OUTPUT
Code:
[email protected] ~ $ fastboot erase misc
erasing 'misc'...
OKAY [ 1.021s]
finished. total time: 1.021s
Code:

Code:

erasing 'cache'...
OKAY [ 2.096s]
finished. total time: 2.096s
Once these two command run with OKAY as the OUTPUT .
It is time to make sure we can reboot into the bootloader with the hardware buttons
So from where you are at in the bootloader screen use the VOL DOWN & POWER buttons to boot the tab back into the bootloader screen ..
Run these command in fastboot in this order
The next command is to just verify your computer can see your device
Code:
fastboot devices

Here is the original thread where the bootit module was tested for the first time -> http://forum.xda-developers.com/showthread.php?t=2291974
The problem was that the installed recovery was too old and incompatible with the bootloader and so could not access the eMMC at all. The bootloader command to boot to recovery is stored in the MSC partition (mmcblk0p3), and the recovery could not clear it. Since the bootloader checks the MSC partition before checking for volume-down, it is impossible to get to fastboot without some additional kick in the butt (aka "bootit.ko").
The correct bootit.ko file to use is the one in "bootit-bootloader.zip": http://forum.xda-developers.com/attachment.php?attachmentid=1985941&d=1369339132 - the older version turned out to be too weak. Note that this is a zipped kernel module, not a recovery-installable ZIP. You need to unzip it on your PC before adb push.
After making it to the bootloader menu and working fastboot, you can fastboot flash a current version of TWRP and install the custom ROM of your choice. No real need for the stock blob, unless you want to make sure you have the current bootloader and a known working ROM.
Here is another thread where bootit.ko didn't help, maybe it was really a hardware problem. But lots of good background info from me. -> http://forum.xda-developers.com/showthread.php?t=2437376

Great stuff! Thanks for this thread Josh!
Now , if I understand this correctly, the insmod command injects a command into the kernel to boot straight to the bootloader before checking misc to break that 'forced reboot to recovery' cycle.
Kinda correct?
In another thread @_that stated once that
Code:
fastboot getvar all
does not return misc as a supported partiton and that
Code:
fastboot erase misc
only "theoretically" erases misc partition. Is that confirmed now?
You guys are great! So much fun to learn this...
I tried to follow this but i get this output:
After pushing bootit.ko to the root and insmod, the transformer reboots directly in the bootloader.
When try fastboot devices, nothing happens just the next line to fill in a command.
Also, when trying then to fastboot erase misc, it hangs with 'waiting for devices'..

I now downloaded from here http://forum.xda-developers.com/showthread.php?t=2588979
And these are working!
So if someone ever have problems command doesn't recognize fastboot commands, its not always the driver! It can also be the fastboot.exe
This transformer is working again !

Great stuff! Thanks for this thread Josh!
Now , if I understand this correctly, the insmod command injects a command into the kernel to boot straight to the bootloader before checking misc to break that 'forced reboot to recovery' cycle.
Kinda correct?
In another thread @_that stated once that
Code:
fastboot getvar all
does not return misc as a supported partiton and that
Code:
fastboot erase misc
only "theoretically" erases misc partition. Is that confirmed now?
You guys are great! So much fun to learn this...

No, I dont think it injects anything into the kernel as there may not even be one in the LNX partition ..
The bootit.ko module comes from the source of the kernel code..
Also the /misc partition is a full partition as shown here ..
Code:
mmcblk0p3
Offset: 1292369920 (0x4d080000)
Size: 2097152 (0x200000)
File system size: 512 * 4096 = 2097152 (fully occupies partition)
Linux rev 1.0 ext3 filesystem
Not mounted
Permissions: GID system can manipulate
Contains: Empty file system
Purpose: Recovery /misc
Referenced by: /system/lib/libandroid_runtime.so recovery ramdisk: /etc/recovery.fstab
Note: File system is referenced in recovery as emmc, not ext3!
Thx Josh

I think berndblb meant that insmod injects something into the *currently running* kernel, which it does. It's used for loading additional kernel modules, usually drivers. When a module is loaded, its "init" function is called by the kernel so that it can hook its functionality into the proper kernel subsystems. My bootit.ko's init function simply reboots the tablet - without properly terminating processes, unmounting filesystems, etc. - so it should only be loaded when no partitions are mounted.

I'm trying to get back to a working recovery. Now I get a cycle of TWRP splash screens. This method looks promising because it appears to rebuild all of the partitions. I can use the Vol Down + Power keys to get to the bootloader (us_epad-10.6.1.14.10-20130801 A03. Can I skip to the fastboot steps? I had Crombi-kk running with rom2sd before I broke something trying to upgrade to zombie-x.
Thanks!

You can skip all the way down to the command "fastboot erase misc". It should kick you out of twrp cycling...good luck..:fingers-crossed:
