Sadly however, i seem to fail when getting to the 4th and 5th step of the guide as what is supposed to happen doesnt happen at all when pressing and holding down the Volume Up button aswell as connecting the USB-cable to the computer on the same time.
this is the things and steps i've done and tried:
1) Tried diffrent buttons then the Volume Up button, like Back button, Menu button and the # button
2) tried having the USB cable connected to the computer first, then plug in the usb cable to the phone while pressing and holding down Volume Up button, also tried with diffrent buttons while doing this, aswell as doing vice-versa (having the USB connected to the phone first, and connecting it to the computer)
So what is the result of all this? the phone only gets into charging mode, and that's about it, either a green or orange LED starts to show aswell.
Some things worth mentioning:
I used to have a very old version of sonybread with CWM (clockwork mod) but before begining the guide i totally cleaned my phone and even re-flashed it to stock rom with SEUS, so currently my phone is using the stock rom without root and a locked bootloader (as far as i know about the bootloader atleast) and currently the phone is working as intendeed with the stock rom, but in all honesty it sucks using it and therfore i'm trying to put in a stable version of Cynaogenmod.
Also i never managed to get the fastboot comand terminal to work fully when launching it from Android\android-sdk\tools as it missed several comands, so in order to actually get the fastboot to work as intendeed i had to launch it from Android\android-sdk\platform-tools which was the fastboot that came with the SDK and not the one downloaded from the wiki's guide on how to get fastboot.
Something more worth mentioning is that it seems like the device manager can't find the phone while being in charging mode or when i do the "Volume Up button" and connect the USB to the computer thingy, however the phone shows up in device manager if its being started up or is being on.
I do however hear the "a USB connected sound" everytime i connect the phone in any way i've tried when it gets to charging mode, but then it never shows up on device manager.
And last but not least, i'm running a x64 W7 Professional machine.
Sorry for such a long thread, but want to try to explain my problem as troughly as possible aswell as everything i've tried in order to rule out as many other problems aswell.
