Working via this tutorial I found these are the steps I have done :

Preparing the device and Connections to the PC 1. Install latest official rom from **** 2. Connect the phone via USB 3. On the phone dial ##3424# to enter DIAG mode 4. Install drivers if needed (on some systems it will find all the right drivers BUT the HTC Diag driver. For me I had to manually force it to take the x64 driver in Windows 7. Once you add the driver it functions perfectly.) 5. Open device manager and look for the device under "Modems" -> HTC USB Modem 6. Double click on HTC USB modem and go to the "modem" tab and note the COM port. 7. Open QPST Configuration 8. Click on "Ports" tab 9. If the port you wrote down is not here click "Add New Port" 10. Uncheck "Show Serial and USB/QC Diagnostic ports only" and your port should appear on the list. 11. Highlight it and click "ok" to add. 12. Close QPST **** You have now established a connection with your device **** Establishing a connection with CDMA WS 2.7 (preparing for memory scan and dump) 1. Open CDMA WS 2.7 2. Under COM Settings (AT Mode) select your COM port for your device, leave baud rate at 115200 3. Click "Connect" 4. Click "Read" (This is not necessary but I do it to ensure I have a good connection to the device. The "read" output will display the phone information in the fields on the left. If you don’t see this information populate you have not established a connection with the device and need to verify your COM port settings and try again.) 5. Click the "Security" Tab 6. Under SPC make sure it is set to "Default (nv_read)" and click "Read" 7. It will display your SPC in the empty box. WRITE THIS DOWN for later! 8. Click on "SPC" button and click on "Send" 9. If you have done everything correctly you will get a popup that says "SPC is correct. Phone Unlocked." 10. Click "ok" * Leave CDMA WS 2.7 open and move to the next section. Scanning for readable memory locations with CDMA WS 2.7 1. Click the "Memory" Tab 2. Under "Scan Memory" leave the start address as 0000:0000 and set the "End Address" to 2000:0000 *Very important, do not let the phone reboot this is why I set the address range to C000:0000 if you go over this value the scan will go out of range and reboot the device automatically. If the phone reboots start the scans over again, the memory locations will change after any reboots. 3. Set the step byte to 16384 4. Click "Start” and you will get spew in the output window similar to this: (these are my exact scans Scanning memory for readable areas: Unreadable area from: 0000:0000 Readable area from: 00F9:C000 Unreadable area from: 00FF:0000 Readable area from: 0108:4000 Unreadable area from: 01DA:0000

I think im supposed to get more readables not sure? so I continued with this I only have 2 readable

So I continue with the tutorial 1. While still on the "Memory" Tab move your attention to Memory / Eeprom 2. Take the first readable area from the scan you have done and enter it into the "Start Addr.:" field. Example 0103:C000 3. for Size (bytes) make the value 99999999 4. Click "Read" and you will get a popup window to "save" a .bin file. I name mine the address range I'm scanning. Example 0103C000.bin 5. The Scan will complete and you will get a dialog box saying the file name and how many bytes were written, click "ok" 6. Do the same for the next two "Readable Area" ( except i only had 2 to begin with )address ranges. The last one may take a while (20-30 minutes) * Do Not Scan on the C000:0000 address range, there are NO MEID or ESN values in this range and if you scan this range you will get the "out of range" error and your phone WILL reboot and you WILL have to start the scanning process over again. 7. Once you have scanned all three address ranges move on to the next section. Do not close CDMA WS 2.7 yet. so I get this error

THe reason you get that error is because cdma ws reads until you hit an unreadable area..thats what the 99999999 is for...It should still let you save the file after the error.. so your scans should be 00f9 at 99999999 and 0108 99999999 and save both those files and seatch for the meid and pesn in reverse using a hex editor.the second scan will take way longer btw because it is a much bigger range...good luck

I can't give specific help, being such a newb and all, but I can give some encouragement. I have 0004 hardware and GB 2.3.3 and now have a perfect phone (knock on wood). Reading about the difficulties above, I downloaded all the software I thought the job might need - cdma ws, qpst 2.7_366, qxdm 3.12.714, ***, and then TeamView for remote interactive access in Win XP and I got some experienced help to do the memory work, hex code stuff. I did do some myself like rooting with Revolutionary. Then after my phone was all mostly good with the expert help I still had no MMS capability. I fixed that by correcting the MMS server via ##data#>Advanced (had to use a password of 000000). Toadal joy here! Then I installed ROM Manager, backed up and put in Team Nocturnal's Stock_RLS 5.0 ROM. Pretty cool and it kept my previous config and wallpaper. I hooked up to XP with HTC Sync and got all my previous contacts that were saved in Outlook from my old phone and Bob's my uncle!
