Hi guys,

I bought a phone from which was an unlocked Vodafone branded E900. I want to use it on o2 uk.

I've been following the thread over here which has been absolutely brilliant.

I'm really struggling to put my phone into Emergency Download mode. I get right up to the stage where I've selected the COM port range and set the DLL and European open firmware in LGDP2_V36_UMTS, but when I connect the phone it just boots up as usual.

How can I put it into Emergency Download mode so it accepts the older firmware?

Would really appreciate the help, not being able to set up MMS or proper APNs is driving me crazy. I cannot use the LG Network Setup app as I get the common "LG ADC feature was been disabled" error.

Many thanks for all your help, I really appreciate it.


Model: LG-E900
OS Version: 7.0.7392.0
Firmware version:

Have you done these steps?

4. The phone call # # 634 # (# # # MFG)
5. MFG application appears, the password is 277634 # * # (* # # APPMFG)
6. Go to Menu then 7.Engineering 3.Port 1.USB Switching Setting then select 2.QC Composite, change the driver for the USB, reboot the phone

Mine wasn't working either till I did that. Then emergency download mode was no problem.

Answered my own question - the software would not access the phone using Windows 7 (64 bit) but worked absolutely fine on the girlfriend's WinXP netbook.

I now have beautifully unlocked European firmware.

Now, roll on Mango

As for Emergency Download Mode, that caught me out. The keys to hold down are:
Vol *down*, Camera and Power.

The instructions imply VOL+ (i.e. Vol Up). Not!
