Yes, you need to do 1.7 ROM1 first (make sure you are "fully" rooted-verify when you boot into bootloader that your hboot version is .76.2)
After that you can go to 1.8.
Read FASTRX8's Tutorial in my sig for a refresher on flashing ROM's
But 1.7 ROM1 is NOT flashed like a normal ROM. You need to place the file on your the root of your SD card named PC36IMG.zip (it's downloaded that way)
Double check the instructions here:

I'm just trying to determine if it's worth me flashing and setting up again or if it's something I won't see any advantage to anyway...

1.7 is running pretty nice for me but I'm always game to improve things...

Well OMJ installed apps2sd in 1.8 (untested) but it recommended that we use a Class 6 card.
deodexing allows themes to be applied more easily. Ive read it can cause stability issues. Just got on 1.8D myself but so far so good.
If you arent interested in themes or apps2sd stay where you are, otherwise jump to 1.8. Read post #2 about flashing your data.img post flash. SO easy to get back all your settings and data.

Ok, I've decided to take the plunge and try to do PART 2... And of course, I hit a snag right away. Ok.. my issue is in the adb shell.. How do I input the info. Totally noob question but...
adb shell
cat /sdcard/flash_image > /data/flash_image
chmod 755 /data/flash_image
/data/flash_image misc /sdcard/mtd-eng.img
I tried input each line and pressing enter. That gave me file folder not found.
Then I tried CAT (enter) and then the lines and that appeared to work. However I'm supposed to get each line repeated back to me 1 time. I got them 2 times each..?? Well, since it looked like it worked. I tried TOAST II pc36img.zip... Well, it appeared as it was working but then after reading the file I got and error:

Main Version is Older!
Update Fail!
Do you want to reboot device?

Lets see if I can even reboot now...

Am I missing something? My command prompt does show # and not $ like tutorials show, could that be the problem. If so, how do I get back to the $ prompt?

[buck12]

so i would have to replace the PC36IMG.zip with the 1.7 one?

Well the LAST error is most likely due to the fact that the mtd-eng step did not work.
Not sure on the first error. Run it again and make sure that you are typing the code exactly as it should be.

WHAT PC36IMG file? Once you are finished with the rooting process you should rename or remove those files. So if you still had that on your card then yes, replace that one with the OMJ ROM 1 file.

Cool, I still have the card that came with the phone, so apps2sd isn't a big deal for me yet. And I am not too worried about themes at the moment, so I guess I'll sit this one out. Thanks bro.

Ok, I'm on my 3rd attempt at reading the PC36IMG.ZIP file..
The problem I keep getting is at the
cat /sdcard/flash_image > /data/flash_image
It repeats the line 1 time but I also get the /sdcard/flash_image: No such file or directory as another line.
The other 2 set of instructions repeat 1 time as they are supposed to.

Ok, 3 time FAILED again. With the error:

Main Version is Older!
Update Fail!
Do you want to reboot device?

Just to clarify, I am supposed to use TOASTs PC36IMG.ZIP file right... Not v1.7 ROM1?? Could that be why it's saying it's old.

Where is app2sd? I can't find it anywhere... Running 1.8D

Forgot to ask if the PC36IMG.ZIP by Toast is supposed to give you an error when you try to open it to see it's content? OMJ's PC36IMG.ZIP I can view no problems.. But Toasts I can't. I've tried downloading 2 others but they have the same issue?? Is that right?

[buck12]

nice i can do this from rom manager right?
