After Relocking Arc, wont enter fastboot mode

Hey everyone, I just relocked my arc so that I could update via SEUS. After the update, initially it entered fastboot mode but for some reason fastboot was't working. Now, the Blue LED does not even come on on my phone. It just glows green for a while and thats it.
Anyone with any ideas on how to fix this problem?
Thanks in advance!

after rolocking fastboot will become unavailable.
you should have read a little through the forum.
Fastboot is only available for bootloader unlocked devices
all you can do is re-unlock again using your old key

Did the same. Your original code will unlock it again.
sinkster

Lol if I put my phone in fast boot and type fast boot devices I get a return with a device
But when I try fastboot flash boot.img I get no partision lol any one care to help

Unlock your bootloader, flash a custom kernel and install a custom ROM. It can be done since you can unlock bootloader.

Yes, it is possible to root. Did you try Eroot from this topic? http://forum.xda-developers.com/showthread.php?t=2219711

Yes, you are doing all good. However, you will need to install fastboot drivers first. Which OS are you using on your PC?

Thanks for reply, I have tried eRoot, It detects my phone (LT15a) runs complete process displays some form in the end asking for phone model, number and comments. I provided data but nothing happened.
I also removed eroot folder in appdata and retry this process again nothing happened.
My phone have rogers firmware
I have copied drivers from sonywebsite to android sdk folder (as suggested in official sony website)

You have to enable USB Debugging in Developer Settings.

Yes it is enabled
Another Question, Do i need to run/Install Android SDK? Or Just Copy pasting files will work?

For eroot , you dont need sdk.
Eroot is a bit laggy so you will have to connect it few times and try to root it with the software

I have installed PC companion as instructed in eroot's thread
I will try again and check if it worked or not
FYI eroot is detecting my phone correctly (My phone is in normal mode, do i need to be in fastboot mode?)

No, for Eroot your phone must be in normal mode, turned on, USB Debugging ticked, Unknown Sources ticked.

Yes Settings were correct
I tried again but nothing changed
(I am using Win 8) previously run eroot on win 7, nothing changed that time either

I have the same problem, but is still running Win8.
Hope you post the solution here - even if you found it somewhere else.

I don't know how Rogers people locked that firmware that its looks like it is impossible to root it
I am not a fan of rogers firmware, I will be okay with any other stable firmware CMW etc
Previously flashed / rooted my Galaxy Gio (GB) within no time, but this Xperia.......
I did tried many methods posted here on XDA, but unable to succeeded (Hoping that starting a thread will help more)

Still looking for successful method, please help me

Can't you unlock your boot loader? You do have fastboot set up correctly right?

Phone with carrier lock cannot unlock bootloader using fastboot. You need to remove the carrier lock first before unlocking boot loader.

Seems I misread... Yeah for him the best bet is to check his fastboot installation.

Hi Friends,
I'm trying to unloack my Z1C using the latest verson of flashtool and after connecting it in flashmode it will not display the window showing model numbers and display a window asking to switch off and connect again in flashmode.
I've tried it on 3 PC's, still not unlocked the Bootloader. What is the difference between unlocking bootloader from Sony official method and Flashtool method. Please guide me.
Regards
Shashi

Iirc the first unlock has to be done the official way, then you can (re)lock using flashtool. And the correct drivers have to be installed of course.

It seems driver problem
Try these:
Connect to flashtool (beta2 or beta4) with device power-on debug off, to see if flashtool can recognize it, and how much it can recognize.
Connect to flashtool with device power-on debug on , to see if flashtool can recognize it.
Connect to flashtool with device in fastboot mode, to see if flashtool can recognize it.
Connect to flashtool with device in flashmode, to see if flashtool can recognize it.
Flashtool may fix some driver error. I just succeeded after hours of bungling like that.
Good luck.

I have all drivers installed.Still can't do it.
Before I had unlocked my bootloader, but I have to Sony service centre for a repair. After that I could not unlock it. My firmware branding is global
