[Q]Reboot into bootloader without power button

Hi,
The power button of my transformer is broken :
I can't power on the device, but I can light on/off the screen.
In order to fix it, I've got to send it to the customer service, but before I need to flash it back to stock.
To flash it I need to go to bootloader or download mode (I dunno what volume+/power is??)
Here is the thing, I did some searches and I tried :
- via adb
- directly from the terminal emulator
- via some widgets with boot mode selection
None of these work, all these methods make the transformer perform a normal reboot.
I'm rooted, and my rom is one of the first ICS beta Revolver.
I just need to flash it back to stock.
Thx in advance.

Reboot into bootloader without power button
Hi fastreward,
It should be possible to boot into recovery from software; for example, I've seen Megatron Parts (for Megatron ROM) boot into recovery after downloading some Plugin.
ROM Manager has an option to reboot into recovery, have you tried it? I think I used one of the options of ROM Manager to update something in my phone (not the ROm nor in my tablet) because it was part of the process, and I believe it rebooted into recovery.
Hope it helps so you can restore your Transformer to STOCK and send it to service.

Vol up + power button get you into APX mode.
(Good only if you're SBK v1 for NVFLash)
If you have CWM recovery, this will boot you into it.

Thanks ! Maybe there is a command to reboot in APX mode ?

If you have CWM recovery, just download an official firmware from Asus website.
Extract the zip file from within, put it on your sd card (or where ever CWM can see it)
Flash the zip file and once reboot you'll be unroot with stock recovery.
(Wipe data, cache and dalvik cache before flashing)

If you can get the tf to do a normal reboot, just hold down the Volume-Down button as it's doing that, and when the screen pops up it will ask checking-for-rck then press volume up to boot into the recovery image, no power button required. (note you do need it to select in recovery, unless you have touch version)
Alternative hold vol-up while soft rebooting to go into APK (sbkv1 only)

stuck on asus boot logo, recovery stuck on booting bootlaoder kernal image

i'm a damn tool and i'm hoping one exists to get my tf300t tablet running again
i had it running beautifully with cm10, then i decided i'm gonna install the touch clockworkmod, but i didn't read the thread properly it was for a stock jb rom, so now when i press the power button, i'm stuck on the asus boot logo with " this device is unlocked" text in the upper left corner, and when i push power + vol down it locks up at " booting bootloader recovery image" , i'm wondering if there is anything i can do to save my tablet or is it bricked and there's absolutely no way of fixing it, thanks for your time

thanks for your reply, i'm not really familiar with twrp, can you go a little more into detail as to how i need to use twrp, do i run it from windows or from the tablet, on my tablet i'm not able to access any type of recovery, it locks up as it's trying to boot bootloader kernel image, thanks so much for your help!

well i just found out by holding vol up and the pinhole reset button then 3 seconds release the reset button while still holding vol up, i can get my computer to detect apx mode
hopefully whith a NVflash version for the tf300t we can recover it

once you in recovery (see 4 icons), use volume down to switch to USB icon, then use volume up hit it twice, now your device is in fastboot mode. Connect your usb cable (make sure usb debugging and unknow source are checked in settings). From your pc now you can flash using script or manuall push it.

i dont think so i cant toggle down or up in cwm, is there some other way to flash it?

There used to be a flash binary that worked with adb (I.e. via recovery). I've not seen or heard of it for a while, but the fact that recovery can still be flashed from booted Android tells me it's still available. ROM Manager and GooManager both allow you to install recovery, so I would start with decompiling those...

First you need to access you tablet (while it's booted in CWM) via adb shell.
Second, you need to verify that the recovery can access the internal eMMC - "ls /dev/block/mmcblk0*" should list at least 8 partitions.
Then, you can put a flashable zip into and the installation command onto the cache partition - the procedure is exactly the same as the method to manually install incremental dlpkgfile updates.

Just want to be clear, turn off your device, then hold down volume down and power button until you see white text displayed on the screen then let go both buttons, you did not see the 4 icons?

my device cant turn off it just keeps rebooting and when i try to turn it off it just reboots. and no the 4 options dont come up. it just goes to asus startup it flashes then it goes straight to cwm

Hold down the power button, as soon as screen went black, let go and immediately, hold volume down and power button, until it boot up again, see if that get you into recovery.

For #5, do we select RCK or something else? When I select RCK and push vol+ twice, I just get the bootloader issue 0x00000000.

when u select RCK does the green Light glow keep on Blinking or not?
Are you using unlocked boot loader??

When I select RCK the blinking stops.
My tablet says in the upper left corner that my device is unlocked.

What problem exactly are you facing?? Can you boot into android??
Do u have CWM recovery or TWRP??
Did u follow all steps?? r u using the same SKU as u r tablet??

The problem I am facing is that I do not have a recovery working. I cannot access recovery at all. I was trying to update the tablet by downloading the official firmware and placing it on the root of the sdcard. But it wont recognize the update when in Android. (I can boot into Android.)

HI
I think then try to re flash your recovery first using fast bot method...then try this guide again..
or the last option is send to ASUS..:silly::silly::silly:

Is this method work with every firmware, and is it work on me301t?

After Update 7-29-13
Similar problem 300t does'nt go past the asus startup screen, when i tried to do a wipe and restore it just goes back to the asus load screen (with spinning circle)and sits and spins, so then I tried reinstalling from micro sd card using the trick where u rename the file to EP201 after trying to reinstall the newest version and an earlier version from the microsd and got the dead android (same results for both )and when I use recovery I get the android guy and loading bar and he fall over dead with error, but when turning it back on, everything goes back to the stuck loading screen. If you connect the tablet to a pc it says usb driver install failed and if you try to force driver install through device manager, the driver install completes but then says the device cannot start. asus sync does not see it , I want to try to put the ep201 file in the SDCARD folder in the internal sdcard but cannot perform this because the pc cannot see the tablet. any help or suggestions would be appreciated.The un rooted tablet Was running 4.2 just fine before i tried the new ota update 7-29-2013 and thats when this happened , I tried to call Asus, since my warrenty had expired last month they said they would fix it , but it would cost me .....i explained that their update is what made it unusable, but they didnt say anything about that fact. and told me the same .... if you have a idea or have solved the same issue PLEASE post
Thanks

hi,
first of all thanks for trying to help
much appreciated
well, using the buttons on the device i can't get to the bootloader screen
it just boots into the stock ROM
BUT i tried it from the the rom with bootmanager (software app from the playstore) and i can get to the bootloader screen
i see the standard three icons
RCK
android
wipe data
if i select RCK it boots TWRP
if i select android it boots the ROM
but i cannot get to this using the physical buttons on the device
volume down and power

Mhhh, can think of 2 reasons:
You're not holding the Volume button long enough.
The button is worn out. Does it work to turn down volume?
