How do I backup my ROM before flashing

[Guest ICP-Fan]

I figured out how to cook a ROM. Now I need to back up my phone before I flash my new ROM and possibly brick my wing.

How do I get this to work?

I tried 'pdocread -l' and came up with the following:

Copying C:\ROM\itsutilsbin\itsutils.dll to WCE:\windows\itsutils.dll

63.94M (0x3ff0000) TrueFFS

| 3.06M (0x30fc00) Part00

| 3.06M (0x310000) Part01

| 57.81M (0x39d0000) Part02

39.73M (0x27ba000) TrueFFS

| 3.06M (0x30fc00) Part00

| 3.06M (0x310000) Part01

| 57.81M (0x39d0000) Part02

9.99M (0x9fd800) TRUEFFS

| 3.06M (0x30fc00) Part00

| 3.06M (0x310000) Part01

| 57.81M (0x39d0000) Part02

982.50M (0x3d680000) DSK1:

| 982.38M (0x3d661a00) Part00

20.00k (0x5000) BTD1:

| 19.00k (0x4c00) PART00

Then I tried:

pdocread -w -d TrueFFS -p Part02 0 0x39d0000 Part02.raw

and got:

ERROR: Unable to open host/destination file - Access is denied.
