Charging Screen - Xperia Arc Q&A, Help & Troubleshooting

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

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

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

Is it possible to unlock bootloader if phone says it cant be?

I went to see if my bootloader can be unlocked from the sony website.
I followed the instructions by putting that code into my phone dailer.
Under the section if it says my bootloader can be unlocked, it says no.
Does this mean I CANT use custom roms?
Is there no other way to unlock the bootloader?
You can always unlock the bootloader, it's just a matter if it's free or not. It all goes back to whether you can use fastboot or not ( the tool used to flash kernels). If you bought your phone sim unlocked it more than likely means fastboot is enabled and you can unlock for free through sonys tool and be on your way to flashing custom kernels. If your phone is sim locked or you paid to get the sim unlocked by a code then fastboot will be disabled. So to rephrase: turn your phone off, hold the search button and plug it in to your computer, if the status light goes blue (and you're not on a CDMA one, r800x) then fastboot is enabled and you can unlock for free through sonys utility, otherwise you're going to have to use a pay service like this (~$24):
http://forum.xda-developers.com/showthread.php?t=1322827
And to answer your question, yes and no, while it's not possible to flash ROMs that use a custom kernel like cyanogenmod without an unlocked bootloader you CAN flash stock based ROMs through the recovery made for locked bootloaders.
I have an R800A from Rogers.
The LED doesn't go on at all when I press the search button.
When I goto sony's website, I go into the phone settings, where it says if the bootloader can be unlocked, it says NO.
You mentioned a paid servers. Is unlocking the phone by allowing it on another network the same as unlocking the boot loader?
No, that's sim unlocking. Confusingly a bootloader unlock will actually sim unlock you as well though, the difference between the two is a sim unlock is a code and the bootloader unlock is done through test points. So ya, if you didn't get the blue light your only option for unlocking is a paid service, sorry.
Well actually an unlocked bootloader allows booting of custom(unsigned) kernel images and can be achieved with various means according to the situation.
Sent from my GT-I9100 using XDA App
Which is what I said in my above post... And the only ways to unlock it are:
- Through sony's online tool if fastboot is enabled and you have an IMEI (sorry CDMAs)
- Or a test point unlock, such as setool2 or omnius, which will enable fastboot
Oh ok sry then, thought u were being general.

Xperia ion Bootloader Unlocking & Relocking

Taken from [Tutorial] Xperia S/P/U/Sola Bootloader Unlocking & Relocking and modified slightly for the ion. I take no credit for this tutorial.
Quick tutorial for unlocking & relocking the bootloader of the Xperia ion.
This is the official way to unlock bootloader
Warning!
This procedure will wipe the /data partition of your phone, so you will loose all ur stored data, settings. SDCARD will NOT BE WIPED!!!
DRM keys WILL be lost forever
Why should I unlock the bootloader?
You can flash custom ROMs/Kernels.
You don't need to worry if the new firmware can be rooted or not as with unlocked bootloader you can always ROOT your device.
SE/Sony gives sneak-peaks/preview builds of latest OS which requires unlocked bootloaders, as they did with Xperia 2011 line (they had ICS alpha/beta), so who knows may be SE/Sony may give early builds of ICS (JellyBean???)
Most of this is taken from lollylost100's his tutorial from ARC thread (all credits for that concise tutorial go to him, i have elaborated on a few things and added device specific changes)
[ Before we begin unlocking bootloader ]
Get the IMEI code for your device: type *#06# in phone dialer to find it out, note only the digits (no dashes)
Download the fastboot package with usb drivers (alternate drivers if the ones in package dont work)
Make sure u have a windows PC with USB cable to connect the phone
Power down your phone and keeping the Volume Up button pressed connect the USB cable to PC this will trigger FASTBOOT mode and windows will start driver installation, extract the above package and point the driver install to that location (usb_driver) folder
Once drivers are installed just disconnect cable and power on device
[ how to unlock ] (official way)
Go to: http://unlockbootloader.sonymobile.com/ and read everything!
At the bottom click 'Start Unlocking the Bootloader'
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.
Click to expand...
Click to collapse
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
If this tutorial is too much for you then itskapil wrote a step-by-step guide (and recorded a video also):
-Instructions: http://www.theandroidsoul.com/how-to...-play-neo-pro/
-Video: http://www.youtube.com/watch?v=LRH3pC7MhEA
(the above videos and some steps are for Xperia 2011 devices, but most the steps are same for Xperia ion)
Info on Relocking bootloader is in next post
Relocking bootloader
RELOCKING BOOTLOADER WILL ALLOW YOU TO GET NEWEST UPDATES & REPAIR DEVICE USING SEUS/PCC
Before we begin relocking the bootloader make sure that u have flashtool download & installed
You can get the latest version of FlashTool from:
http://androxyde.github.com/Flashtool/
Download link is under "Installation" tab
If you have not use FlashTool before read this thread:
http://forum.xda-developers.com/showthread.php?t=1526866
Download this FTF:
Xperia ion -> LT28-ION_Relock_bootloader_Dogsly-TEST.ftf // Mirror 1
Flash this FTF via FlashTool:
When it says enter flashmode, power down device and keeping VOLUME DOWN button pressed connect usb cable to phone, the device will now enter flashmode (green LED)
After this file is flashed reboot phone
Bootloader will now be relocked!!!
Incase device doesn't boot DO NOT PANIC... You can flash stock firmware FTF anytime to get back to stock ROM
P.S.: there is no official way to relock bootloader
So because my phone says I can't unlock the bootloader, does that mean I can never unlock the bootloader? Or do I have to wait to be able to root it first?
PS: I got my ion from Best Buy so is that why? Will I ever be able to unlock the BL ? I've rooted and unlocked my x10, back in the old days lol but I'm just wondering if there's any difference with getting a phone from at&t directly or from the sony store and best buy.

Have to wait to see if another way to unlock the bootloader is discovered. Root and unlocking the bootloader are two different things that accomplish or allow different things you can do on the phone.
IE rooting allows you to uninstall system apps & bloatware, backup apps/data, make changes to build.prop etc. Unlocking the bootloader will give you access to fastboot so you can flash custom roms/kernels and other images such as a pre-rooted system image to gain root.
I wonder. If we can not unlock the bootloader for some LT28at, why is there a key to unlock it? I did the Sony bootloader unlock for fun and apparently they have a key for my LT28at even though it says bootloader unlock is not allowed.

I understand that works for lt28i but I'm referring to lt28at the us model of the ion and why there is a bootlloader unlock code when we can't unlock it.
see if it works
Has anyone with an ion that has
Bootloader unlock allowed says Yes

tried to unlock it via the sony site and if you did and it was successful have you tried to relock it using the file linked above? Would be nice to know if that works.
Possible fix?
If the LT28i can be unlocked, what if we flash the international firmware on our LT28at's and then do the LT28i method? Maybe a stupid question but this is the first phone I've had that's a challenge to do stuff like unlocking and rooting. My last phone (HTC Aria) was extremely easy.

Flashing firmwares does not change the ability to unlock the bootloader.

Kinda figured that
I tried to relock the bootloader. The flash pass but the phone can't turn on after that.
*I reflash the stock kernel again and the phone can power on now.
So here is the result, once you relock bootloader, you need to flash back the stock kernel in other to turn on the phone. Hopefully this will help those people who got stuck after relock bootloader.
Hello guys
I was just wondering, if bootloader unlock or flashing cutom kernel will allow to use sim cards from other mobile operators (European for ex.) ?
I have an ability to buy this device in us through my friend. but Im interested if I would be able to use it in Europe I was thinking of buying xperia p or s, but they dont have microsd card support.
Im not interested in using LTE networks. Just common 2g.
I planning to use it like a second android device as a multimedia player instead of my galaxy s wifi5.0. (because of good sound quality and other features).
Thanx a lot for responses

No. You can't unlock the bootloader of the lt28at and you can't sim unlock it either. Best bet is get an international version not one from the US.

If you see this
Code:

or this

then you can enter fastboot mode.
If you see this

You have to make sure that your phone has unlocked bootloader, if it says "bootloader unlock allowed: yes" it doesn't mean your phone is unlocked, it only tells you that it can be unlocked.
If you have TrackID, try to play it, if it can be played, then the bootloader is still locked.
For unlocking, try the link below. And don't forget to thank them.

1. rooted the device
2. installed CWM
3. wiped everything
4. installed UHD and choosing just one app to install
5. unticked reboot
6. wiped Dalvik Cache ONLY
7. reboot device from CWM
8. Enjoyed UHD
UHD is stock based so it will work on locked boot loader, if it doesnt then you're doing something wrongly.
