device keeps disconnecting and rebooting while trying to use flashtool

[sid3091]

Hi, im on the latest .101 FW and im trying to downgrade to .67 so i can root and install a new custom rom. Ive installed a custom ROM before on this phone following the rooting procedure by this guide
http://forum.xda-developers.com/showthread.php?t=2458268, but now every time i connect to flashtool64, it says device connected in flash mode, but disconnects after a minute or so. What am i doing wrong? I've got USB debugging and unknown sources on.
Thanks, sid.

actually your have to first select the rom in flash tool then "wait" for tool to prepare files then the tool will prompt then connect your phone

My ZL has been acting weird lately, powering off on its own, and requiring a power source to boot back up.

I tried connecting to flashtool last night, and it works, but the green led that supposed to light up, just quickly blinks on then off, and stays off.

Yet flashtool is still telling me my device is connected in flashmode..... weird.

I was too scared to try and flash an FTF because i have a feeling the phone will just randomly power off.

My LED does the same, just blinks on and off when connecting to flashtool.
When I connect in flashmode and wait for a minute or so, the phone boots automatically.
But it always behaved like this since I bought the phone .
Flashing works like it should and it always worked. I think it's normal.

Double check that your drivers are installed correctly

Which particular drivers are you talking about? How to re install them?

I should mention that I'm trying to unlock my bootloader while in existenz v4 ROM. Does this make any difference? Or should i flash a .67 ftf and unlock my bootloader.
