Connect the one end of the USB cable to your computer. Then while holding the menu button on your arc s (the right one) connect the other end of the USB cable on your phone. Keep the button pressed until the LED turning blue

1) Download custom kernel in .img format. Put kernel file in fastboot folder.
2) Turn-off phone.
3) Press and hold "Menu" button, then connect phone to computer through USB cable. (LED will turn to blue color, means in fastboot mode)
4) If you using Windows 7, press and hold "Shift" button and right click mouse on fastboot folder. Select "Open command window here"
5) At command prompt window, key-in "fastboot flash boot C:\fastboot\CUSTOM KERNEL NAME.img", click "enter".
Remark1: If you put fastboot folder at D drive, then change C:\ to D:\
Remark2: example: custom kernel name is Arc_OC.img, then type C:\fastboot\Arc_OC.img
6) It will start flash custom kernel.
7) Reboot phone.
8) Done.
Personally, I've always had problems with fastboot working properly for me (possibly) due to some driver errors, which unfortunately refused to be fixed. So, I've always used flashtools instead, and frankly, it may be more simple for beginners. So, here are the steps if you wish to utilise this method instead.
1) Ensure that you've got the latest version of Flashtool.
2) Download and install the required fastboot drivers by going to your drivers folder in the Flashtools folder and running Flashtool-drivers.exe. You do not need to do this if you already have them.
3) Press and hold the menu button while connecting to the PC through USB. Ensure that the LED light turns, and stays blue for the duration of this process. This signals that the phone is in fastboot mode.
4) Return to the main screen (with the logs) and click on the lightning icon near the top left. This is the mode selector. Select fastboot mode and you'll be taken to a screen that looks like this.

}
5) Click on 'CHECK Current Device Status' and ensure that the log states your device is in fastboot mode.
6) Click on 'Select kernel to Flash' and direct it to the folder where your .img file is stored. Check the logs to know when your flashing is successful, though it should only take a few seconds at most.
And with this, your kernel should be successfully flashed. If it doesn't, then check if you have the right drivers installed, or if you did everything right.

Can you get into fastboot? You get there by pressing and holding first back and then power button.
as i said before, it shows only the image above on every key combo
turn it off, plug it in via usb, hold back and power
if you know where your fastboot.exe is then cd into the path in cmd.
if you don't then unzip my attachment and put it in your c:\ and type these commands
Code:
cd\
fastboot devices
if it gives back a serial then it is not bricked and you can flash a RUU
It will likely not give a signal back on fastboot devices, as it isn't in fastboot, but it wouldn't do that in hboot mode either so you can't use that info for anything.
I've seen a couble of these, and you should still be able to flash a ruu. If it's a gsm desire(you should have a sim-card), download and run the following ruu while it's connected: http://www.htcdev.com/process/legal_download/152(the ruu is the .exe file inside the .rar)

FYI, when it's in that state it is booted in RUU mode, which is pretty much the same as fastboot.
if you don't believe me, plug your phone in while booted into a rom and type
Code:
adb reboot oem-78
fastboot devices
fastboot getvar boot-mode

well, congratulations on following bad advice which has got you in an even worse situation... Nothing much you can do. You're S-ON, and you have an un-overwritable RUU (unless a newer one comes out). Can try to flash it again but whether that works is anyone's guess.
Why it doesn't boot now? What's wrong

Good question.. that could be anyone's guess!
After some searching on the forum, the only other similar issue someone had I could find was in the G2 sub forum (see link).

My Droid Incredible has been a wonderful phone and was running CM 7.2 flawlessly when as of a few days ago began only booting to the HTC start screen. I loaded HBOOT in attempt to get into recovery, but the volume buttons aren't working. Any thoughts or advice would be greatly appreciated.

That is very strange. Obviously its not a hardware issue as the vol down key works to get to hboot. So my guess would be that hboot is corrupt somehow. Have you tried reflashing hboot? Mabey hboot will see the file and let you use vol up to install it. But im guessing that it wont let you use the keys for that either. I would use a pc and fastboot to flash an ruu. To do that:
Download the latest ruu http://dinc.does-it.net/Stock_Images/4.08.605.15/PB31IMG.zip, and place it on your pc in the same folder as fastboot.exe.
With the phone connected and in hboot open a cmd prompt to where fastboot.exe is and type the following.
Code:
fastboot devices
- Above line should output your serial #.
Code:
fastboot erase cache
Code:
fastboot oem rebootRUU
Code:
fastboot flash zip PB31IMG.zip
- If you get a failed error, type the above line again, it happens sometimes when flashing a complete ruu.
Code:
fastboot reboot-bootloader

Well, first of all thank you for taking the time to respond. I really do appreciate it. For some reason I could never get fastboot to recognize the device even though it showed up correctly in the device manager. I was however able to download the file and put it on the root folder of my sd card. I then boot up in HBOOT again, and it installed it through that process. It first relocked HBOOT, then reverted back to factory settings.Then I found out I had a second issue.The power button apparently had been sticking. I believe this is why none of the buttons were not working, and also possibly why it kept running a boot loop. But, all is well now, thanks again.
My phone is arc and I installed like this.
1. Xperia Arc S
2. Super Jelly Bean 2.0
But I tried to install fxp209 for easy updating, but I could not flash boot.img.
ths adb driver installed as this picture.

Default fastboot flash problem
First question is your bootloader unlocked!!
If yes try flashing like below
How to fastboot a kernel
(1) Download kernel .boot img place in folder Windows/Flashtool/Firmware
View attachment 1787067
(2) Press lightening bolt
(3) Select Fastboot mode
(4) Connect phone in Fastboot mode (Hold Menu Button ) then connect your phone to pc
(5) Choose select kernel to flash in Fastboot on pc
(6) Wait -until finished 10 seconds tops
(7) Done! switch phone on boot to cwm wait for vibrate/blue light press down/up/or back button depending on kernel or age of phone
Also try booting into fasboot manually as above (step 4)
Also if the fxp kernel not working try another compatible kernel there is plenty in the forum
First question is your bootloader unlocked!!

He is using CM10 based ROM so I think his bootloader must be unlocked.
To OP: You can try to flash a kernel with a fastboot and CMD like a real man ; D. Google how to use fastboot.

Lol I knew that But believe me I have seen people try to flash cm based rom's/kernels with locked bootloaders that's why I never presume it is unlocked unless they have stated it in the post that it is unlocked :good:
My phone is "bootloader unlocked".
And I tried to flash at command line, but it didn't finished.
The correct command is fastboot flash boot kernelname.img See the link in my sig for more help.

Yes, I did "fastboot.exe flash boot boot.img".
Try again without an .exe extension. Just type fastboot flash boot kernel.img
After command "fastboot flash boot kernelname.img", command line shows;
sending 'boot' <6430 KB>....

That's how it's supposed to be. Show us the rest of CMD content after typing that command.
Hello,
ive been trying to change rom (not the first time),
and while in fastboot mode
any trying to burn boot.img, but in order to do that I must open the usb thruogh fastboot mode,
and my phone say it cant open the USB.
is it a problem with the sense 5?
ive downloaded again the htc sync manager.
and I can load the usb from the when the phone is on.
how can I fix it?
thanks for reading!
Download and unzip the attachement.
Open a command prompt to that folder.
Connect your device
Set it in fastboot mode
Type "fastboot devices"
Tell me what you see.
Actually sounds like you are referring to "failed to open usb master mode" and if that is the case it is simply because you have the cable plugged in when you are switching between hboot and fastboot. each time you want to switch, pull out the cable then reconnect when you have changed modes

Your device is recognized by fastboot, so you can flash a boot.img, the command is:
Code:
fastboot flash boot boot.img
Make sure you have copied the boot.img to the fastboot folder on your PC.
You cannot see your device in windows explorer when you are in fastboot.
Edit: You can in recovery when you mount your storage.

Hy guys,
my 16 years boy make a full wiped on devices.
the device is stuck in fastboot but cannot acces recovery and is not synchronized with my pc.
when i push hboot and select recovery is suddenly go back into fastboot
i try many different methods to flash recovery with adb devices but list attached is empty and the adb drivers are installed on device manager android usb devices ( My htc )
can somebody give my some advice with this ?
tnx in advance.
Regards
ADB fastboot folder (just extract it to C:\ and you're good to go)
- Connect your device and PC using usb data cable
Step 1
Flashing recovery (before relocking your bootloader)
- Download recovery.img
- Save it to C:\ADB folder
- Navigate to ADB folder and click on any free space while holding the shift Key
- Choose 'Open command window' here
- Once cmd is started use this command
Code:
fastboot devices
and check if your device is listed, then type
Code:
adb reboot fastboot
to reboot your device. It should start in fastboot mode. If it's not, shut down your phone and restart using power + volume down buttons, pressed at the same time. Once Hboot starts just navigate (using volume up or volume down buttons on your device) to Fastboot and press the power button. Make sure FASTBOOT USB is displayed under your specs.
- Enter
Code:
fastboot flash recovery recovery.img
into the cmd window and press enter to flash your recovery.
- If it's successful go to step 2, if it's not try again.
Step 2
Relock Bootloader using Fastboot:
Now you need to relock the bootloader, otherwise the Stock RUU can't be installed.
- Copy command to the cmd window
Code:
fastboot oem lock
- Press enter
Your device should now be relocked.

}
Then just place your stock RUU on an sd card, start in bootloader and select Fastboot. Your device should pick the file up as an update and flash on its own.
