THERE IS AN EASIER SOLUTION FOR ROOTED PHONES!

There is no need to go through all the hassle of following the instructions here:

Especially if you do not know anything about adb or how to run commands.

These instructions are ONLY for rooted phones running custom ROMS

It might work on stock roms, i have not tried so i do not know if it does or not.

So you want to know the easy way to get lock picker working on 2.2, yes? Well it's a lot more simple than you think.

First, you are going to need two roms on your SD card, you will also have to do a full wipe so save anything you want to keep.

This was only tested to work on a Sprint EVO. I do not know if it will work on other phones but i do not see why it wouldn't.

First step

Download 2 different roms, you will need an Android 2.1 and 2.2 rom.

The two roms i used for testing were:

Fresh EVO 1.01 (Android 2.1)

Calkulin's EViO 2 ROM v1.5 (Android 2.2)

I've also done this using the new Fresh EVO rom, 3.03 or something and it worked perfectly fine on there too. I did this about 4 months ago and it worked fine and haven't had problems since.

Once you had the two roms downloaded you need to transfer both of them to your SD card under the root directory.

Second Step

Reboot your phone into recovery. There are a couple ways to do this by either using an app (like rom manager) or by powering off your phone completely, then pressing and holding volume down + power button. You will come to a white screen, use volume buttons to go down to recovery, press power button to select.

Once you are in recovery you need to wipe everything.

Everything meaning cache, dalvik-cache, and data/factory reset.

After you wiped everything go back to main recovery menu and select flash zip from sdcard

From there select the Android 2.1 (Fresh EVO 2.1 for our example) rom to flash 2.1 on to your phone.

Third Step

Once your 2.1 rom has been flashed let it boot up into android and here's where you need to decide if you want to use the lock pattern or not.

I prefer to use the pattern unlock instead of no lock at all, so that is the only method i have tested.

You MUST set the pattern lock before installing lock picker or your exchange account!!!!

You can set the lock pattern under settings, then security.

Once you have set your lock pattern it's time to download Lock Picker. Open up the market place and enter in all your Google info to be able to download from the market. Search for Lock Picker, download and install it.

When you open lock picker it will ask you to setup an exchange account, go ahead and do so.

Go through all the setup and get your exchange up and working. It might ask you for a password, use something you will remember but don't worry about putting in a password.

Go back to Lock Picker make sure it is enabled.

Fourth Step

Shutdown your phone and boot back into recovery.

Once you're in recovery DO NOT WIPE ANYTHING!

Select flash zip from SD card and flash the Android 2.2 ROM you downloaded to your SD card.

Let everything install and reboot your phone back into android.

Voila! You are done!

OP can you PLEASE PLEASE PLEASE put this information in your original thread, i have seen too many people post on here asking about 2.2 and i'm almost positive i found this solution on some random forum somewhere embedded in posts. Most people are not going to look this far into the thread to find this part.
