Is it possible to flash roms on the LG Optimus 7 in any way? I don't mean custom roms I just want to flash an official release build on my device.

I never had it. I'm using a pre-release device with 6536 build.

Then, I think you might need to wait for the first update, as there really isn't any ROMs floating around the web for Optimus 7 yet...

Not true. There may not be any development topics here. However, in the actual WP7 Development forum on XDA, most of the modifications and hacks apply to the Optimus 7 as well (with the exception of the HTC specific or Samsung specific ones, duh!)

There's new thread in the development forum for this device. Teaches you how to flash the firmware along with the correct firmware for specific countries.

Hi all,

I am trying unsuccessfully the method mentioned above without any success since yesterday night.

If followed carefuly the steps but when launching "LGDP2_V36_UMTS.exe", I can't enter Emergency Download mode.

Everything is well installed, my modem was located in port COM4, I have the correct DLL and .dz rom.

But when I press the "Start" button, and plug in with the USB the phone when LG logo appears at startup, nothing happens.

If I set the "USB Switching" to QC Composite, using MFG, when connecting the phone, ports COM5 and COM6 become active (still nothing on port COM4) in LGDP2_V36_UMTS.exe, I get "ErrNum502 EMERGENCY MODEL FAIL" after a few seconds.

Any idea on this? I am currently running an LG Optimus 7 under NoDo Orange-FR branded (would like to flash with the European rom).

Thanks in advance.

Thomas

The roms available for download are for 7004. As far as I know, you cannot flash the older version rom atop the newer OS. Your best bet is to reverse the nodo update with Zune, then attempt to flash the desired rom.

Hi Kapanak,

I see, thanks for your reply. Do you know how to "downgrade" my phone using Zune? I went through the whole parameters and sync list and found nothing.

Thanks,

Thomas
