[Q] Stuck in Download Mode

Hey everyone I'm quite new to android, and I'm currently stuck in Download Mode after trying and failing to install Twrp 2.7
I was previously rooted, tried to install Twrp via Autorec, however when I ran the app it soft-bricked my phone and put me into Fastboot mode.
I followed http://forum.xda-developers.com/showthread.php?t=2476972 method, and got back to Download Mode.
I am currently in the middle of returning to stock through http://forum.xda-developers.com/showthread.php?t=2432476 using the .TOT method.
I'm fairly close to repairing it but my only issue is that I cannot get my computer to recognize my phone. Neither in Device management nor adb devices anymore.
Therefore I cannot change the port to COM 41 to flash the .TOT file.
I constantly tried installing drivers for the phone both 3.10 and 3.08 but still no recognition can anybody help?
Some more info about the phone:
it's the D801 variant but its on Wind (Canada) not T-mobile
it was previously rooted
it did not have any recovery software installed
no roms had been flashed previously.

So, you flashed a ROM via cwm.
A few lines later you mention that you can't install cwm... is there something I miss????
Whatever;
Can you enter Fastboot/Flash mode manually/via PC and flash a new ROM from there using Flash Tool?
Have you unlocked your bootloader?
Have you tried following these steps?
That's pretty much everything I can think of.
I hope it's just a software brick... :fingers-crossed:

No I said I can't install a rom via recovery it gets unknown error ....
But Now I have another question how to enter mt5689 in Fastboot/Flash Mode manually via pc .....with flash tool......
plz can anyone tell how to enable usb debugging mode when phone is bricked.....
if you want to install a stock rom via odin, you dont need usb debugging to be on, just boot into odin/download mode (google to see how) and flash a stock rom, then do whatever you need.

Now listen to me very carefully! Don't even try to flash a new firmware to your mobile which is not for your mobile and face the same fate as did! Your place is needrom.com. just contact the site administrator for your device model and he will help you... Believe me!
Hi.....thanx for your reply brother.......
I downloaded the rom from needrom.com for my device mtk6589.....which is actually mtk6572
but after installing a rom with spflash tool....... my hand set gets dead....no usb no display no charging nothing.......
I flashed with spflash tool and process completed successfully with no error... but after installation of rom I safely remove usb of my device ... but when I try to turn my phone on then nothing happen.. now my phone is hard bricked.... Now Plz guide me what I should do now....
I heard from someone that I can be fixed with volcano box....
Plz can anyone tell me..
Did you choose correct model and version?

Stable rom as in stock rom? or a stable custom rom?
in any case. if you have cwm or twrp you should be able to access the file on your computer, or even transfer it to an sd if the phone has it..
if its a custom rom flashable zip though you you might as well just flash it.
if its a stock rom an you cant aces recovery then you have to redownload it to your pc....

Now you can't unbrick your phone because you overwritten the preloader of your phone. Remember: when flashing with SP flash tool you mustn't flash the preloader. The preloader is the file that makes possible the flashing with SP and now that you have overwritten it or flashed the wrong one, you probably won't be able to recover it. Take it to service center.

The recovery mode is not working but i can go into download mode. I tried flashing the phone with lg flash tool. but i when i load the dll it says wrong dll. i also tried the dll that bypass the model check but still wrong dll.. What should i do now?
