[Q] Lost USB connection after SE bootloader unlock

After searching the forums i still havent found a solution.
The problem is i decided to unlock the bootloader using Sony on my Arc S a day ago.
Now when i connect the USB it will not connect to the MSC or MTP though the computer pings and sony companion comes up but says the usual reboot etc.
I have tried all the different combinations of turning USB debug and other things on and off but to no avail.
Has anyone else had this problems and fixed it?

Try reinstalling PC companion with the option in phone connection.

Sorry to say thats not working :s
Any idea if factory reset may work? Holding off doing that cos hate having to put everything back on lol

Factory reset did not work
Any thought on my next options would be appreciated?
Can i still install a different ROM to the memory card? I have no recovery so i dont know if i can do much of anything?
Thanks for any help.

How did you unlock your bootloader

is your camera and home button not functioning too ? reflash back using flashtool or if it doesn't work, use wotanserver..

I now have it running after using Wotanserver twice :s
The only problem now is it wont root (Bootloader is still unloacked, did it via Sony)?
I tried Doomlord but it says read only as it tries to do it.
I dont know how to use flashtools as for some reason it wont install on my computer (possible Kasperski stopping this).
How do you reinstall the ADB drivers cos i think that may be the problem.

Try the link at this post

Managed to get flash tools installed and that rooted it
It now wont update OTA so wondered if sony companion will update but will flash tools root after?
Lots of thanks to everyone for there help seems i have question after question lol.
Just when i think i know what i'm doing i get another phone and it starts again. Sticking with sony now though even if they dont have Gorrilla glass

you can't update via Sony Companion / OTA because you have unlocked bootloader..

You have to flash stock firmware with flashtool and wipe anything. Flashtool will recognize your phone.

The problem is that flashtool not recognize the phone...after a while the phone is connected to a computer, the LED changes to red color, then it does not help (POWER + VOL UP) .. only after some time returned to SONY logo.
Already starting to lose hope: (. Is there a way to repair.

I think the correct drivers are not intalled. You check this ? When led light change color as you said, maybe windows have trouble witth phone/flashtool driver

Previously, I had installed the drivers, and I was able to upload a new flash, etc. Suddenly, plugging into your computer, windows 7 x64 does not detect the device.: (
Do you have drivers for x64? Thank you for your help ..

Correct drivers are not installed. Download the correct x64 drivers for fastboot. Now wen u connct your phone in fastboot. Just keep the device manager opened and right click on the fastboot device that pops up on the device manager. From there go for a manual device installation by doing have disk and pointing to the right winusb.inf file. Search the forum for this method and relax, your phone is not dead.

[Q] Help me, my Xperia S cannot detect by PC

Dear all,
My Xperia S cannot detect by PC, even I called to Sony service centre, they also cannot help me over the phone and ask me send to repair. The problem is this phone are old and not worth for repair.
This phone detect new software update (currently is 2.3.7) but need to use USB with PC companion. I suspect the phone USB port got problem, although still can use it to charge battery but windows OS cannot detect and install driver on it. Tried few PC also the same.
My question is, is there a way I can download the firmware and I using wifi transfer the firmware to phone and flash from the phone itself ? (I manage to download firmware - LT26_6.1.A.2.55_CE.ftf but it need USB connection to flash it)
Appreciate for whoever can help me here. TQ so much.
Best Regards,
Kenny

1) Try different Cable
2)No way to wireless transfer or anything
you need USB in order to update
sorry
edit:
did not notice you stating PC Companion
do what @Ben36 says and use flashtool and flash the FTF that you have downloaded

[Q] Xperia Arc Disaster! Help please!

Hi everybody,
I own Sony Ericsson Xperia Arc (LT15i) which no longer lives under the warranty time period. It became extremely slow, so I decided to flash a new ROM on it in attempt to see if that made it any faster. I rooted it and installed ClockworkMod Recovery on the phone and attempted to flash Xperia Ultimate HD 5.01 through CWM. The installation went perfectly fine, however after I did the reboot my phone doesn't get past the Sony Ericsson logo.
I've looked up all sorts of ways to fix soft bricked and bootlooped Arc's but none seem to work. When I try to use flashtool, I can't seem to be able to connect the phone to the computer and Windows comes up with "USB Device not recognized" and flashtool automatically aborts flashing. When I try to use PC Companion to repair the device, Windows doesn't recognize the device and neither does PC Companion. The same thing happens with Update Service.
I cannot enter flashmode, cannot get anywhere past the Sony Ericsson logo (including trying to access ClockworkMod Recovery) and cannot seem to get Windows to recognize the device. All drivers are installed both from Sony and flashtool.
Is there any other way I can recover my device? Thanks in advance for all help!

Hello,
I can pretty much understand your situation, but this is where we start to have a better understanding of our own device and learn from our mistake.
In fact if you want to use flash tool, you will need to prepare your PC to recognize your mobile, by means of installing appropriate drivers, commonly known as Google SDK drivers.
I shall resume somehow here and try to find a good link for you to read :cyclops:
1. Your PC need to have latest version of JAVA
2. Install Google SDK, choose appropriate drivers and apps to be installed
3.Install flashtool and appropriate devices drivers.
Try to follow this link :
1. Installation of ADB drivers and SDK : http://forum.xda-developers.com/showthread.php?t=1830108
2. Flashing Kernel and Rom. Be careful with compatibility and other issues, you always have surprises here
http://forum.xda-developers.com/showthread.php?t=1996665
The above link is for HTC if im not wrong, try searching for ARC you will find it, there are loads of tutorial posted on XDA..
Here you go : http://forum.xda-developers.com/showthread.php?t=1508585
Dont forget read and read until you understand every single terms.
See Ya . .

The problem is that you have GB kernel, but using ICS ROM. These 2 do not work together.
Try another USB cable and/or USB port and try Flashtool/PC Companion again.

Tried that. Still no results. I've also tried using fastboot, and yes I did install all the drivers as well as the Android SDK along with the Java DK. When I enter
fastboot devices​
I get no response... When I try to flash a kernel using
fastboot flash boot bootARC.img​
It says waiting for device forever. The phone is plugged in and the blue light is on. The screen is still off though. When I connect it in fastboot mode to Flashtool it has the same problem (doesn't recognize the device).
Would Sony be able to fix it for me if I handed it in? Even though my warranty has been void for over a year I could probably just pay for the repair. At this rate I doubt it's possible for me to fix it...

Which Windows are you using?

Well that might be the issue,W8.I have W7 and XP never had a problem.
Did you try to run flashtool and connect the phone via usb(turn it off and just connect it don't hold any buttons,if that doesn't woek try turning it on and then connect it)-so that way flashtool might detect the device.Hope you'll get it to work.If nothing helps than try searching on google about these issues for win8.

Did you increase your system and data partition into 419 MB and 440 MB? Because if you haven't you'll get a bootloop with Xperia Ultimate HD 5.01 since this rom needs that space. I read that you have to flash Arc S kernel to achieve this but im stuck at this point because the partitions won't change for me :/

To use fastboot, install the drivers by this method.

Flash Mode not working and can't get recovery or root

I bought a xperia ZL C6506 4.4.4 .283 firmware used for the soul purpose of rooting it and using it with AppRadio Unchained in my truck but it is giving me hell. All i need is root access and everything i have tried has failed. I downloaded flashtool and all the necessary drivers but i can't get the phone into flash mode. I can get it into fastboot just fine. I am trying to flash the .230 firmware so i can root and then go back to .283 but flashtool throws an error in fastboot mode. I tried twrp recovery using adb fastboot command line but it just didn't work. I am new to sony and I'm pretty annoyed because i bought it because it was supposed to be easy as opposed to my GS5. Towelroot says device not supported. Easy root throws adb database out of date errors or just hangs at waiting for device. WTF!
Any thoughts on how i can fix flashmode to work with flashtool or get root access. I am not interested in doing much modding with this just need root.
Thanks

I guess flashmode is disabled in your region by your manufacturer. Strange but usually they disable fastboot mode too. Were you able to goto flashmode when you intially bought your mobile?
While connecting to ur laptop using Usb cable press and hold volume down button and see if the green flash led stands. At this this if you have already installed the needed drivers for flashtool , it should be able to detect your phone. If you have windows 8.0 and up make sure that you sign your drivers before installing it to laptop, else your drivers will fail to install in your laptop and flashtool will not detect your mobile even if you put it in flashmode.

Oddly enough i plugged it in this morning without opening flashtool or anything and tried to put it into flash mode and it worked. Windows installed a seperate driver and then i got everything working.

If the LED light blink red then green then turn off. That doesn't mean it's not working.
