Charging Screen

I recently got my arc unlocked (network-unlocked), and when i try to go into fastboot mode, my phone instead boots up, shows the sony ercisson screen and then shows a battery charging screen. Im trying to get into fastboot mode.
Help?

Are you holding down the menu button before you plug it in? (Rightmost button)

Yes, and im on world generic firmware

Is your boot-loader unlocked?

no, i am trying to get into fastboot in order to unlock it. I am wondering if its my firmware which is blocking fastboot from enabling?

Can you explain? My phone is unlocked, but it wont boot into fastboot(LED doesnt turn blue) so i cant unlock bootloader

Read the guides, if the phone came sim unlocked then its user error somewhere.

Im using this guide: http://www.theandroidsoul.com/how-to-unlock-bootloader-xperia-arc-play-neo-pro/
i am just unable to boot into fastboot. All i get in fastboot.exe is < waiting for device >

Go to the first link in my sig, and you'll find a simple method to check if you can unlock in the standard way, try that and report back.

I did that, but i didnt see "bootloader unlock allowed:yes" in configuration, I didnt see anything of that at all. I saw SIM in Sim card, and there was a 0, if that means anything. Also, what firmware should i be on to check this?

I think you'll have to use SETool then, ie remote unlock.

Nvm...flashed the newest firmware and checked it again, bootloader unlock allowed: no

[Q] bootloader status

How Do I find out the bootloader status (Locked/unlocked ?) of my xperia ARC.
actually I unlocked it official way, then relocked and updated to .42 fw using PC for giving to repair under warrenty. its over and I want to unlock bootloader again. whats the best way I'm on fw .42 baseband 56.
thanks a lot in advance.

dial from your phone to check status :
*#*#7378423#*#*
service info --> configuration
for me, the best way is via fastboot..

dear gogo,
I've tried that, the service info will tell you "bootloader unlock allowed = yes"
it will not tell you whether your phone is locked or unlocked state!

It will tell you.
Mine is unlocked and says " Bootloader unlocked: Yes "

that means your bootloader is still locked, and you were allowed to unlock it.

So that means I can do the same exercise again to unlock I mean official way?
In that case se will provide me new code to unlock?
I don't remember the old code they provided
Regret for the seeking the clarification again as I don't want to endup in trouble later.

Yes, you can unlock again.
Request the code again and you'll see if they provide it again.

it's ok.
I've tried it.
the unlock code is still the same code you had received before.
the remaining question is whether you sure to unlock it again or not, as standard user doesn't need to do such thing.
bravery comes from experience.
that's it bro.
I think your problem has solved.

For the info...
Bootloader unlocked: Yes
Means fastboot is enabled and the bootloader can be unlocked the official way
Bootloader unlocked: No
Means fastboot is disabled and therefore the bootloader can only be unlocked by other means
The best way for you to check your bootloader status is do identify in s1tool or similar

You have to pay someone to unlock your bootloader for you and flashtool won't cut it. R800x as far I know there is no key to unlocking bootloader for free. I highly recommend Alejandrissmo a fellow reputablesite and xda member.

This is incorrect. I had my phone bootloader unlocked by ashergrey over a year ago via an unlock code. Even though I am unlocked I went to the sony unlock site and it gave me an unlock code to my email. So you should only need to get that unlock code, and make sure you have the latest flashtool drivers. There are tutorials on this in the Development and General section

OK but the problem is that the one driver(android_winusb.inf) they specifically ask you to install isn't installing...device manager doesn't show bootloader interface file... Thats what's stopping it from unlocking...

Xperia play tp engineering BL unlock help needed

R800x 2.3.2 Kern=2.6.32.9 [email protected]#1
Build=edream3.0 Zeus cjs.
Not sure if anyone can help out since there aren't to many people viewing the xperia play forum anymore, but if I can get the bootloader unlocked that would be awesome. So far I've tried.
S1tool: returns aid:dead doesn't hurt the phone but it doesnt unlock either. Flashtool tried also does not work returns cannot unlock officially. Or something similiar.
Sony unlock method put in flashmodeconnected
Fasboot devices: returns code without errors.
Fastboot getvar version returns v3 fastboot no errors.
Command to unlock with key always returns failed got the key twice from Sony so the key is not to blame.
Maybe it is because it is a custom bootloader since this is the hdmi version of the play. Or because it is the r800x any help and or suggestions or fastboot commands would be awesome.
Well it appears I cannot unlock this phone as of yet because it is a brwon phone aka engineering phone. red phones are retail and blue are stock from the factory. So Now all I have to do is locate someone who knows how to get brown phone keys like @Blagus or @DooMLoRD lol!!

I sent you a pm with some info that I hope will help. I had first tried the Test point method on the R800x and got an error message that (from what I could find on Google searches) meant the Test Point method wasn't compatible with the R800x. I just ended up using the Sony Official bootloader unlock method because I wasn't worried about losing DRM keys.

Hey man.... I looked over some info that I had saved when I unlocked my bootloader last year. I also read through some threads to refresh my memory. I posted some things here ( http://forum.xda-developers.com/showthread.php?p=59710197 ) for someone else that also might help you with unlocking your bootloader.

still no luck. bootloader unlock allowed no. flashtool returns not rootable still as well s1 tool still not working says hash not supported sony method also not working.

My R800x didn't have yes or no for Bootloader unlock Status. In fact, I believe that I read in multiple posts where Verizon had left this out ( here's one example: http://forum.xda-developers.com/showpost.php?p=55238100&postcount=74 ). If yours has a "no" in there, then it sounds like the HDMI version of the R800x must be different.

trying to unlock the bootloader, but fastboot doesn't recognize the device

running windows 10
adb recognizes the phone when it's booted up. so i type in cmd "adb reboot bootloader", then the LED lights up blue, which means it's currently in bootloader mode right? so i type in cmd "fastboot devices" but nothing happens. no devices are listed.
any advice? a bit desperate right now. thanks in advance!
