[Q] Have I bricked my Arc S?

Hi,

I got a Sony Ericsson Arc S that I tried(4 hours) to update to Android KitKat without any success.

I tried to follow this guide : http://techglen.com/2013/12/04/update-xperia-arcarc-s-android-4-4-kitkat-cm-11-custom-rom/

But to not lose the Bravia function it states that I need to do a TA partition backup first and to do this the phone needs to be ROOTed. To get the phone ROOTed I tried this : DooMLoRD's Easy Rooting Toolkit [v4.0](zergRush Exploit) but it gave me this errors :



(Firewall and antivirus off)

The phone was on the next to latest official version so I tried to update it with the PC Companion from Sony Ericsson. It said that I hade to press down the back button at the same time as I connected the USB and then on the next step when it hade began the update it stated that I did not need to hold the key anymore so I released it and then the update stoped with error. After this the phone can´t be booted? When starting upp the phone I see the Sony logo and then a image with a phone and a warning triangle!? Nothing more happens, the screen goes black. I have tried to remove the batteri and I have tried to do the update again(the PC Companion do not recognize it).

Is it possible to fix it or is it forever bricked?

Okay,

I am now trying to follow : https://github.com/LegacyXperia/Wiki/wiki/Installing-LegacyXperia-for-Dummies and this is what I have done :

1. Install Mobile Flasher by Androxyde
2. Start Flasher
3. Hold the menu button at the same time as I put in the USB

The Flasher will responde with this :

07/042/2014 18:42:26 - ERROR - Drivers need to be installed for connected device.
07/042/2014 18:42:26 - ERROR - You can find them in the drivers folder of Flashtool.

I have runned the Flashtool-drivers.exe in C:\Flashtool\drivers folder, checked the Sony Ercisson Xperia Arc, Xperia neo, Xperia PLAY... but at about 80% completion a new wizard is shown(Device Driver Installation Wizard) and this will fail :

Sony Ericsson (WinUSB)... Install failed
Sony Ercisson NET Install failed

I have also tried download the Arc S drivers from this site : http://developer.sonymobile.com/downloads/drivers/ but Im not sure how to install these drivers? there is no setup?

When connecting the phone to the USB a Other Devices > S1Boot Fastboot will show up in the Device Manager with a exclamation mark?

There is problems where ever I go with this?

I have tried this :

1. Start Sony Mobile Flasher
2. Connect the USB without doing anything else
3. Flasher says that the phone is connected
4. I click the flash button in flasher and choose Flashmode, then OK
5. Choose the folder where the firmware is(LT18i_4.1.B.0.587_Generic_Global.ftf)
6. Click Flash
7. A dialog open and closes
8. It ends with error

Okay, I have now restarted Windows 8.1 and the stock flash was successfull. The phone is now starting up as it should.

I have also reinstalled fastboot according to this : http://techglen.com/2013/10/01/abd-and-fastboot-guide/

When connecting the turned on phone to the USB it is found as a ARC S in the Windows Explorer. So far so good.

But when doing this :

1. Turn off phone
2. Start fastboot(admin) in cmd
3. Holds the menu button and connects the USB so the led goes blu
4. Type fastboot flash boot boot.img and enter
5. It will no just show < waiting for device >

I also notice that when I connect the USB Windows sais that it does not recognize the device anymore. Probably becouse its in fastboot mode?

So what do I do now? I suspect that Im missing some USB driver for the fastboot mode on the phone?

Someguyfromhell said:

Windows 8 and 8.1 have signature verification, which does not allow the installation of fastboot drivers.

Tried the first example but that did not work. Feels like I invested to much time in this already so I will place this on hold and see if I will ever come back to fix it.

I have a Samsung S3 on service so my thought was to use the old Sony Ericsson ARC S instead of the HTC Titan but it is a bit to much work to get latest android running on this phone and even if it is done there will be buggs.

So Thanks so far for your help.

Okay, I tried on a Windows 7 64Btis as well and with the help of this video : https://www.youtube.com/watch?v=dUsA9HxZjJE I got the drivers installed so the S1Boot Fastboot driver dont got a warning.

But when running the fastboot it is still waiting for device. The blue led is active so the phone is in fastboot mode and I can see in activity field that it is connected to computer. Yet the fastboot will not find the phone? This feels all but unstable.
