Help!!! Arc s s1 boot fastboot failed

Hello anyone...
I have a friend's Xperia Arc S LT18i I would like to root. I already got code to Unlock the Bootloader. I have followed all the procedures on SonyMobile. But when I hold the Menu button and plug the USB in, no Window shows up to choose the winusb driver as explained on d sony website. Instead, I just get that notification on the oc taskbar saying "installing driver...." the it fails.
I tried a trick... I ran the command to unlock the bootloder " fastboot.exe -I ..... 0x (key)" while the device was on and its says "Waiting for device" which means its waiting for the device to go into bootloader mode. So while that command is waiting... I opened a new cmd and ran "adb reboot bootloader" The first command window then said something like "InfoUnlockKey needed... " or something cos I dont have the phone with me at the moment. Thinking of getting it again when I find a solution. Who could help with what to do? Thanks

these are the possible reasons for that to happen
1) u dont hav the drivers for ur phone
download "pdaNet"(just search in google) install with ur phone connected.
2)if u r using USB 3.0 connect to USB 2.0
in my laptop i cant enter fastboot when i connect it to usb 3.0
samething happened to me too at first this fixed it.

Are you sure it says that your bootloader can be unlocked in service menu
7378423 in dialer i think
Sent from my Xperia ion using XDA Premium 4 mobile app

If some one can find me a way to unlock the bootloader on L28H i will be very glad...cuz i just bricked my phone and i`m flashing a rom for locked bootloaders

Go to: http://unlockbootloader.sonymobile.com/ and read everything!
At the bottom click 'Start Unlocking the Bootloader'
Quote:
First, you should confirm that it is possible to unlock the boot loader of your phone by checking the service menu. In your phone, open the phone dial pad and enter *#*#7378423#*#* to access the service menu.
In your phone, tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.
After you have verified that you can unlock bootloader, scroll to the bottom of the page and click "Continue"
You will get "Are you sure prompt" accept it by clicking "yes i am sure" (i assume that you have read an understood it)
Then accept the "legal terms"
Finally you will get a "Create Unlock request" page, enter your IMEI (sometimes the last digit needs to be removed for this to work), name and email address
You should now receive your unique unlock key, its displayed on screen, SAVE THIS KEY SAFELY
Extract fastboot_with_Android_USB_file.rar and open fastboot folder
Hold SHIFT and right click on the background of the folder
Select 'Open command window here'
Connect your phone in fastboot mode (turn phone off, hold Volume UP button and plug in USB Cable) [make sure drivers are installed as explained above)
In the cmd windows type in fastboot.exe -i 0x0fce getvar version
If a value is returned (it will return 0.5), it means the phone is correctly connected
Type in fastboot.exe -i 0x0fce oem unlock 0xKEY and replace KEY with the key which you received earlier.
Your device should now be bootloader unlocked

Is the same for any ION. Some can be unlocked, some can not be unlocked.

do you have the Unlock key from sony?
and what happens when you plug in the USB cable? I didnt faced the any issue with USB 3.0 at all but it may be an factor for you.

Yes i have the key from Sony but when i connect the phone to pc in fastboot my PC says that it could not recognize it and my phone then boots to the battery logo....EVEN THOUGH i have installed the DRIVERS via the flashtool (flashtool drivers)

then try to boot in fastboot mode via flash tool itself.
once device is in fast boot mode follow the instructions to unlock the boot loader. and It is not necessary to unlock bootloader to install custom rom. it is only required if you want to install custom kernel. recovery can be installed without unlocked boot loaer.

Help!!! Flashing HTC desire eye 910x cant be done

Guys
I have tried all the mentioned ways in this site to flash my system but i am no where..
My issue starts with unlocking bootloader, when ever i try to unlock it using windroid or cmd commands or htc dev the phone reboots to a black screen and at the bottom says fastboot mode and just stucks there for a while till cmd says faild to get keys or something like it ..
And the phone keeps it at that screen until i power it down, i have all the drivers installed the right way and adb drivers as will and cant get the phone to unlock bootloader.
Any solutions please..

Hello moh.naser. Have you tried doing thjs from the official Htcdev site ? Because all information about doing this are listed there in 6 steps..As you mentioned you have installed all drivers with the appropriate way,but check again 1st if your device is compatible 2nd if you wrote the token right and 3rd if you pressed the yes option to unlock the bootloader..Pls let me know

how to check if bootlader is locked

Hi Folks
I just got the Media Pad M2 8.0 and I want to check if the bootloader is locked or not
because there is no dialer installed I can't use the code I found in other forums
is there another way to find out?

Yes, there should be. You need to enter fastboot mode on the phone - i.e you need to get into the bootloader screen. The bootloader screen (usually called fastboot mode) will tell you if the bootloader and FRP are locked or unlocked - If it is locked, you should see "PHONE Locked" and "FRP Lock" in green, otherwise it should say "PHONE Unlocked" and "FRP Unlock" in red if the phone has been properly unlocked.
You can enter fastboot mode by either using ADB ("adb reboot bootloader", first make sure to enable developer options first as detailed in the Rooting guide, and then enabled USB debugging), or by first shutting down the phone and then powering it up while holding down the VOLDN (Volume Down) key. Of the two methods, I'd recommend the ADB method because the hardware keys method is usually hit-or-miss for me - sometimes it takes me to the bootloader, sometimes it boots normally into the ROM.
If you're on Windows and need the ADB and fastboot binaries, you can install the "15-second ADB installer" found in this thread.

Thanks, that worked, took me a while to figure everything out...
and it appears that my device is unlocked...

Bootloading Kyocera DuraXV Extreme

Hello, I'm having some serious trouble bootloading my Kyocera DuraXV Extreme (AOSP)
I've went into developer options and activated USB debugging and allowed OEM unlocking.
But I get stuck on rebooting into bootloader mode. I've tried different approaches:
1. Starting up phone while holding volume up and down buttons. Then select "reboot to bootloader".
2. adb reboot bootloader command
Both options reboot the phone without going into bootloader mode.
Seems Kyocera decided to somehow lock the bootloader mode. Anyone know of a workaround here?

My comments below are based on the belief that you are trying to unlock the bootloader.
I am not familiar with this phone but generally the two steps mentioned by you are not enough to unlock the bootloader. After those steps, you'll have to issue a command via adb to unlock the bootloader and if successful, then you can boot into it for further operations. The command will vary between devices, so search and profit.

Thanks, this cleared it up a bit, you are right, I'm trying to unlock it.
I'm trying the command fastboot flashing unlock but only getting the message < waiting for any device >. I read somewhere that I might need some USB drivers but I don't know where to find them. I have the latest version of the standard USB drivers for the phone, but as I understand it I need special drivers for this?

I'm trying to follow the steps here: https://www.ifixit.com/Guide/How+to+unlock+the+bootloader+of+an+Android+Phone/152629#s317298
I get stuck on the step:
Enter the command adb reboot bootloader
Wait a couple seconds until your device rebooted into the bootloader, then enter the command fastboot flashing unlock
My phone isn't "rebooted into the bootloader", it just reboots. It gives the message "< waiting for any device >" when I write fastboot flashing unlock

It should be a driver issue. When the phone is on and you connect it to the PC/laptop and send the command 'adb devices', does it show an alphanumeric value? Likewise, when you are booted into the bootloader by key combination and send the command, 'fastboot devices', does it show the same alphanumeric response? If so, the drivers are installed properly. If not, either you don't have the correct drivers or they are not installed properly. Try installing the drivers again after disabling driver signing in Windows on your PC (search for it on Google).

Hello, can you clarify what you mean by "booted into the bootloader by key combination"?
My problem is I cannot boot into bootloader at all.
Any attempt at doing so results in a normal boot of the device.

Are you sure that the key combination for booting into bootloader is what you described in the first post?
1. Starting up phone while holding volume up and down buttons. Then select "reboot to bootloader".

I see Power plus Volume Up as the suggested one from a Google search. Try that.
If you can't even boot into the bootloader with the correct key combination, I don't know how to help you further since we are starting to go in circles. I am sorry.

Hello, thank you so much for trying to help me. It seems I can't boot into bootloader. Volume up + power gives the same result as what I did before.: It opens a "Recovery" menu where I can choose reboot to bootloader, but this option just reboots the phone.
I've been in contact with Kyocera and they say:
Thanks for contacting the Kyocera Customer Support. We will be more than happy to assist you with your concern
In this case allow us to inform you that since this device is a basic phone , it doesn't have the option to activate fastboot mode. By installing something that will change the way the phone works , that will void the warranty that came with the phone. We as manufacture can not help you to modify the software that came with the phone.
So the phone's fastboot mode has been deactivated. But since it's an android I guess it should still be possible with some workaround. I just don't know whee to start, I've been researching for a week with no result.

Something interesting ehre, maybe someone with more coding knowledge can tell what's going on.
I found the source code for the phone and located a file called recovery.c which I guess handles the menu I see when I press volume up + power button. Maybe some clue to why the phone isn't going into fastboot mode?
