Are you confirming your upgrade PUP matches the correct MD5 checksum?

Download the CFW you want to install (I suggest Rogero 4.30 v2.03): http://psx-scene.com/forums/content/...function-2768/
The correct information is as follows:

MD5: 5f7434a46f7909689b00558a06071689
Size: 192 MB (201,591,424 bytes)

Download an MD5 Checker for your system such as...

Windows: MD5 Checker - CNET Download.com
OSX: Download MD5 for Mac - Create and compare MD5 checksums. MacUpdate.com
Linux: uses the 'MD5SUM' from terminal

1. Copy the update pup to a FAT16/32 formatted USB drive into the following directory: x:/PS3/UPDATE
2. Rename the PUP to UPDAT.PUP (no 'E')
3. Run the MD5 Checker on the UPDAT.PUP file - MAKE SURE IT MATCHES THIS MD5: 5f7434a46f7909689b00558a06071689
4. If it matches, update directly from the XMB
5. If it doesn't match, don't even try to update until you download a copy that matches.

PS: TB EBOOTS won't work with the new CFW's. Update the game, or copy the original eboot back.

my phone works for installing pkg's, music, videos, etc, but i cannot use it to update CFW :| idk why.
I use my external HDD as my USB for when I need to update CFW.
