[Q] CAN'T FASTBOOT: No Blue Light (Phone is Network Unlocked, Tried Debranding too)

Hi!
I've recently bought my Arc with an O2 (Ireland) contract but the phone doesn't seem to have any apparent signs of branding...... ie. no logos or O2 apps (apart from the default homepage of the browser which is set to O2). Also, I recently got an unlock key from the network, so it's network unlocked too.
My goal is to root the phone. But first I have to unlock the bootloader, right? So I went off to unlock the bootloader but my biggest problem so far is that I can't get the phone into fastboot mode- ie. when I disconnect the phone, then turn it off completely and press and hold the menu button (on the bottom right) and reconnect it........ the light is supposed to turn blue but it doesn't! The light never turns on but instead, the sony ericsson logo comes on for a few seconds and then the batter charging symbol comes on.....
I've also managed to flash its ROM to a debranded version but still couldn't get into fastboot mode even in that....
Can somebody please let me know how I can get my phone into fastboot mode?
Thanks a million!

you don't need to do anything with the bootloader unless you're flashing roms or you want x-recovery. flash 2.3.2, root with gingerbreak and then upgrade to 2.3.3 ota. as in here. http://forum.xda-developers.com/showthread.php?t=1115542

Thank you! Will give it a go in a minute and see how it goes!

Ok so I tried what u suggested and it works! BUT, it's only a temporary solution..... after I upgraded to 2.3.3 and did a hard reset, the phone was back to its original unrooted state.
Is there any way of permanently rooting it so that it remains even after a hard reset?
Also, how do I get the phone into fastboot mode?
Cheers.

Fastboot is disabled on "branded" phones (basically any phone from a carrier) regardless of SIM/network-lock status or debranding. See this thread: http://forum.xda-developers.com/showthread.php?t=1037874

Here in Germany Arcs from at least Telekom and Vodafone are unlockable. When they are just branded.
Didn't test it myself on my Arc that had a Telekom branding but read it in different forums.

Why do you need to make a hard reset?

If your phone was branded to begin with, then I do not think that you can unlock the bootloader.

if i knew this before i would never get the phone. at least i have root and i could remove the bloatware. something is something. I hope someone will come with the unlocking option soon.
thanks for info

If it's an ex-contract vodafone then you should be able to unlock, they stopped sim-locking contract phones last year. I know cause that's what mines is...

It was locked to vodafone and got theNAC code so i unlocked it. Then i flashed stock debranded Rom but stil no change. If anyone know any solution i would be happy.

Thank you soo much, (esp to all that helped) I have another question:
Has any one seen the new update for the Xperia Play? I have not updated yet, however I was hopeing that some one can shed some light on this update, as I am not sure if it is ICS or is it a normal firmware upgrade? I am on 2.3.3, on R800i. Should I do the upgrade or no?

I'll do my best to help you, but we're going to need more information.
1) What Model of the phone do you have?
2) Are you absolutely sure that you unlocked the bootloader correctly?
3) Have you tried searching for and flashing the basebands for your model?
4) Can you link to the .ftf files and the CM9 wiki page for our access to be quicker?
And protip for the future: Include as much information and as many resources as you can about the problem. We can't solve insanely vague problems.

Model is R800i, Yeah I unlocked the boot-loader correctly I done it before when I had CM9, Bit of a noob so I haven't flashed any baseband for my model ill have a search for them now and report back. The FTF file was a 2.3.3 generic UK file found in this forum.

I have read posts about that. And it seams like the only way to reunlock is is to go with the paid method of unlocking... sorry

sounds like you need the fastboot drivers installed... can you use flashtool? have you checked if it did indeed unlock your bootloader?

Build 10.1.A.1.395 - Is this the newest

Hey
I've had a Xperia ZL for about 2 weeks now, love the phone.
I'm using Build 10.1.A.1.395
Mine is a Rogers C6506 Variant - I got it brand new (off contract) from Kijiji and unlocked it via code.. I'm using it with LTE on Virgin Mobile Canada without issue.
Am I using the newest firmware? PC Companion says so, but from what I can find my firmware is from March and there was new firmware out in May, is this correct?

Never heard anything about 395...anyways,253 is the latest firmware available(307 is going to come soon,,also a 4.2 update is nearby),try updating through Sony update service(Google this for more info)
If you feel that I've helped you in any way,,please hit the thanks button
Sent from my C6502 using Tapatalk 2

.395 is the oldest, actually. So no.

Since your phone is branded with Rogers, you will need to wait for Rogers to update their product which will probahly never happen. Maybe they will update when Sony updates to 4.2.
If you want to update via PC Companion, just flash your phone with a generic 395, 434 or the latest 253 FTF with flashtool and the next time they (Sony) release an update you will be able to receive it via PC Companion or even OTA.
Remember that flashing a stock Sony FTF file doesnt void your warranty since you dont unlock your BL.
Don't wait for Rogers to update, you'll wait forever....
Have fun...

Edit: Found some threads reading up on it. Like Odin with previous note 2
This is great news. Is this difficult? Would you be so kind to point me to the correct files or provide a little guidance? I want to do this yet can't afford to muck up.

I am having the same issue with my phone. If I unlock it though Rogers
can I update it directly from Sony PC Companion or will I still have to wait for
Rogers updates and would have to flash it like you guys are recommending?
Also would unlocking it through my carrier enable me to unlock the bootloader?
Thanks

If you flash the Sony generic, you will get the updates through PC Companion or OTA as they get pushed out by Sony. Rogers is extremely slow to release new builds and i really dont think they update unless its like from ICS to JB or something major. But not from 4.1.2 to a different build of 4.1.2.
Flashing your phone with the stock FTF will not change your BL unlock allowed to YES.
If your phone is from Rogers like mine it is probably on Allowed unlock BL = NO
But it doesnt matter, all firmwares can be rooted and recovery can be installed so unless you want a custom kernel you want to tweak, there really isnt any point of unlocking the BL. Besides, its voids your warranty.

Great! Thank you for your help! I will try it out this weekend.
One more question about the Rogers phone and unlocking it with them.
Will the unlock BL allowed switch to yes? or does the unlock just enable me to switch
carriers?

BL unlock does not change - will still not be unlockable
Sim Unlock and BL Unlock are not the same.
I want to flash the FTF but want to make sure I'm doing the right file - Where do we get the newest Generic FTF that will work on the C6506 (Rogers) Variant?

BigStyle84 is right. Do not confuse unlocking your BL with SIM unlock.
SIM unlock allows you to use your phone with any carrier provided the baseband is compatible. Unlocking the bootloader allows you to flash the Kernel which isnt something I would recommend doing if your not comfortable with. You can still flash other ROM's via recovery if you are rooted.

Hyelton has a thread where you can download either the 395 or 434. The 253 is also in XDA somewhere, I can't remember from which thread I got it from...
Here is thread where the FTF for the 395 or 434 is for your C6506:

Looks like the latest 4.2.2 is getting released as we speak....

Might as well wait a few days for this one to get released and update to it or flash it once the FTF gets leaked for the C6506
