Timemachine problem

Hey guys,
I am new to PSP and I have a question about timemachine. I have a slim with 4.01 m33-2 and it works fine with most stuff (not timemachine, the CFW). I have installed timemachine per the install guide and everything seemed to be successful. However when I pandorize my battery either by hardmodding or I have also tried it with ultra pandora v4. I take out the battery and hold circle and put it back in it takes me to the menu that I used for loading my 4.01 m33 CFW. I have tried formatting the memory stick within the PSP and added all files needed to run timemachine, but then it just sits there with a blank screen with just the power light on. I have held the circle button for about ten minutes (good finger cramps) because I have read that it takes a while to boot up to 1.50. Finally I figured it should not take that long. I had to put in another memory stick that had the same files for my CFW and then I could get back in to it. I then normalized my battery and it will boot up fine back into my orginal 4.01 CFW.

I am not sure if anyone else has had this problem. I have search and searched, but have not been able to find a solution and I am scared to brick my slim. I am really just trying to get away to play some of the homebrew apps (I.E Bookr) on my psp slim. The only way I can find is to run kernal 1.50 addon. And I guess it just does not run on slim. So if there is a better way other than timemachine please advise.

Thanks!

no, you need to have the timemachine ms and battery inserted to use 1.50 kernel.

Do I have to format the MS a certain way for Timemachine? Like you do a magic memory stick? I simply just copied all the files that the install guide said to. I put the timemachine folder in the x:\psp\game folder and I put the 150.pbp, 340.pbp, and the 360.psar files in the root of the psp memory stick. I ran timemachine and run the files in the order the guide said. All passed OK! Then I pandorized my battery. Then took out the battery, held circle, with the memory stick with TM on it in the psp and put the battery in. It then just boots to the service mode for 4.01 m33. Here is the options for the menu I see below:

Install 4.01 m33
Install 4.01 OFW
NAND Operations
Hardware Info
Test M33
Shutdown
Reboot Device

X Enter

Please let me know if I am missing something.
Thanks!
