If you used the official update route your phone must have been relocked during the update to 7740 hence you have no ability to side load apps. Roll back to the previous 7720 version through Zune and stick with that if the phone was Interop unlocked, if it works.

If your bootloader has changed to version 5******* theres not a lot you can do yet to unlock your device, apart from the Goldcard method.

I thought that the newest zune doesn't backup the complete device any more... is this true? is it possible to go back to 7220 without hard resetting your device?

very strange...
in the morning tried to downgrade to 7720, but unsuccessful. after few hours tried again, but it seems that my phone is half-bricked...

anyway, connect the phone to pc, zune started and i see "restore"!... right, i can restore to 7720 and now my apps works!

tried now to update to 7740 offline, but the same situation: can't use apps!... tried to interop-unlock in 7720 with htcinteropunlock.xap, but can't find in connection setup "interop unlock".

please help me, because i really need to update to 7740 because of outlook forward message update and also because i need to use these apps (navigon is one of them).

it is possible to have a 7740 phone with interop-unlock?

thx.

You might be lucky and stay unlocked by updating from the restored version of 7720 to 7740 by trying one of these methods:

While running your unlocked 7720 install the attached Advanced Configuration 1.5 .xap swipe the screen and go to 'Tweaks' and make sure the box 'Prevent phone from relocking' is ticked. Now run the 7740 update and see if that keeps it unlocked.

If the above doesn't work go back to the 7720 backup and install U2M7720 V1.2and follow the instructions below before running the 7740 update.

Select U2B2, complete provxml and tap on done

Finally just tap on Chevron Unlock (will exit U2M7720)

DO NOT RUN Connection Setup now

Update to 7740

NOW run Connection Setup

Let me know if either of these methods work for you, and could you please let me know which bootloader version you have on the 7720 and 7740 ROM versions, I know you have already updated and it could be the same for both now.

The bootloader version is found by powering off then powering back on while holding the volume down button in. To get out of bootloader mode hold the power button down for a few seconds until the phone turns off then power it back on.

first method not work.

try now the second. which version of connection setup must be installed?

just tried: it seems that even this method failed. connection setup don't start and the other apps don't work.

i will try again to restore and install connection setup from marketplace.

spl - 5.10.2250.6 (132274) mng

update: still locked...

It'll be the 5.10.2250.6 bootloader that's keeping the phone locked, there is no easy work around for it that I'm aware of, unless you flash back to a manufacturers ROM using the Gold card method then install a custom 7740 ROM using RSPL/HSPL.
