Hi there,
Has anyone got a way out of this.....
I have a rooted C1905 that I have been playing around with. I want to try CM11 but boot loader unlock fails with a "FAILED (unknown status code)" report after I send my unlock code. I then thought I'd flash back to stock using S.U.S. but that fails too saying that I have a customized rom... which I don't!!! I seem to be stuck! is there anyway to force a stock flash?

Cheers

Have you checked if your bootloader can be unlocked? Go to the dialer, type *#*#7378423#*#* then go to Service info => Configuration. In rooting status, it should say "Bootloader unlock allowed: yes", otherwise it won't work. About your flashing problem, try connecting the phone directly in flash mode before opening SUS, by turning off your phone, holding Volume Down and plugging USB cable or by flashing a FTF file through Flash Tool...

Flashed an FTF of the latest but still can't unlock the bootloader. still get "unknown Error" and it wipes my apps.
Also can't use "repair my phone" on PCC as it says I have a Customised Rom, could this be due to me trying tools like flashgordon and debloat/deoxing flashing or routing? if so how can I get back to a stock state for a UK XM so I can start again?

Nope, but try this anyway.
1. Disconnect your phone and turn it off but keep the cable attached
2. Open PCC and go to Update
3. When it says no device found click the blue repair link
4. Choose Xperia M when asked to
5. Follow the instructions

I have a locked bootloader and modified ROM and it works flawlessly. Keep us updated

Hi there,

Thanks for the help, unfortunately it doesn't work! PCC recognises my phone ok so I carried on to the "repair my phone" tab.

and this is what I get after it's downloaded the firmware and tries to flash it...
