Downgrade baseband

[waterproof93]

Hi everyone,
So here is my problem,
I want to try custom ROM on my LG Phoenix but i already have the new baseband installed and i've read that i need the old baseband to use the kernel for the color fix and to have a proper ROM with GSM...

I already tried this: [HOWTO] Flashing baseband (radio) via LGMDP.exe - xda-developers
but i'm stuck here:

and the browse image window doesn't appair...
anyone have a solution for this?

I tried also KDZ with this: [HOWTO][PICTURE GUIDE]Update your firmware using KDZ Updater - xda-developers
but it soft bricked (boot-loop, no recovery access) the phone 2 times already with no luck... (i don't know if i missed something, maybe i have to wipe all before ??)

If there is a simpler solution i'm here to listen...
(maybe a patch to use old baseband for the new baseband user, since there is a patch to use the newBB for the OBB User...)

Thanks for helping me.

I'm on mobile & can't see see your links.
Have you tried flashing the v10e .kdz file?

if you dont have anything to boot to then your stuck tring to figure out the KDZ tool.
i suggest you go give the FASTBOOT STARTED thread a read if you havent yet.
make sure your diabling the LG modem in device manager.

I wanted to ask about that. Everybody keeps saying that you have to disable the LG driver in Device Manager. I've used the kdz tool twice now (lol), and I never messed with Device Manager.
Don't know the significance.

idk either, you would have to ask a dev why.

Anyways thank you guys,
I was right for kdz i full wipe was needed and it worked but at the end I'm back on newbb no custom rom working so good on the Phoenix :/

Waiting for a new kick-ass kernel!!

I think I may have figured out the reason why people say to disable the driver in Device Manager. I think that's for "LGMDP THUNDER v1.5 (Operator).exe" (which I've never used). You do not need to disable any drivers in Device Manager when you use "KDZ_FW_UPD.exe" (the KDZ flasher).
