Sprint palm centro 690 d062 (Gandalf) custom rom help

Post by jacksonm111 » Thu Apr 09, 2009 5:43 pm

I am unable to install a ROM update that I unzipped and rezipped from the ROM files that I extracted from "Centro_1_07_SPNT_DesktopUpdater" installation package from Sprint.

These are the steps that I took.

(First, I tried things verbatim)

1. Unzipped the Centro_1_07_SPNT_DesktopUpdater.exe archive.

2. Copied the following files to an SD micro card

(system)
gandalf-htc-tpl.zip.md5.pdb
gandalf-htc-tpl.zip.pdb
gandalf-ipl-dvt.md5.pdb
gandalf-ipl-dvt.pdb
gandalf-ipl-ev1a.md5.pdb
gandalf-ipl-ev1a.pdb
gandalf-ipl-ev1a_el.md5.pdb
gandalf-ipl-ev1a_el.pdb
gandalf-ipl-evt1.md5.pdb
gandalf-ipl-evt1.pdb
gandalf-ipl-evt1_el.md5.pdb
gandalf-ipl-evt1_el.pdb
gandalf-ipl-evt2.md5.pdb
gandalf-ipl-evt2.pdb
gandalf-ipl-p.md5.pdb
gandalf-ipl-p.pdb
gandalf-palmos-tpl.zip.md5.pdb
gandalf-palmos-tpl.zip.pdb
gandalf-spl.md5.pdb
gandalf-spl.pdb

(application)
gandalf-palmos.zip.a.pdb
gandalf-palmos.zip.b.pdb
gandalf-palmos.zip.c.pdb
gandalf-palmos.zip.d.pdb
gandalf-palmos.zip.e.pdb
gandalf-palmos.zip.f.pdb
gandalf-palmos.zip.g.pdb
gandalf-palmos.zip.h.pdb
gandalf-palmos.zip.i.pdb
gandalf-palmos.zip.md5.pdb

(launcher)
RomUpdater.bprc
RomUpdater_enUS.oprc

3. Inserted the card into my phone and installed the RomUpdater files using Resco Explorer 2009.

4. Copied the system and application files to RAM.

5. Launched the RomUpdater (typed "gand" at the so-called prompt) and successfully updated the ROM.

(Then, I tried to re-zip the files)

6. Merged the application archive pieces into a single gandalf-palmos.zip file using O'Razoff's PDB2ZIP rexx script. Validated the MD5 checksum, "c5796e49382c400b5c6d0303f7d78001," (using DiamondCS MD5 checksum program) against the MD5 checksum embedded in "gandalf-palmos.zip.md5.pdb". They were the same.

7. Back on the PC, unzipped gandalf-palmos.zip to a new directory.

8. Re-zipped the unzipped files from this new directory into a new archive with same name as the original, "gandalf-palmos.zip," using Winrar. (I.e. I did not change any files in the archive.)

9. Split the new archive into 2MB parts using O'Razoff's ZIP2PDB rexx script.

10. Calculated the MD5 checksum using the same program as above.

11. Overwrote the checksum embedded in the "gandalf-palmos.zip.md5.pdb" file mentioned above using Orebro's VbHexEd.

12. Copied the new application files onto SD Micro card.

13. Repeated steps 3, 4, and 5. On step 5 got MD5 checksum error. I was unable to proceed further.

My reasoning was that if I could get an unaltered, but re-zipped, ROM to install, then I could try adding/removing applications.

I noticed that the original gandalf-palmos.zip file was 17275 KB, whereas the Winrar archive was 17250 KB (fast compression) and 17283 KB (normal compression). So, I experimented with a few zip programs to see if I could get the zip file size right (7zip and Info-Zip). No luck, the 17283KB file produced by Winrar was the closest.

My questions are:

1. Is it even possible to do what I am trying to do? (My instinct tells me that it is.)

2. What am I doing wrong?

Any insight would be appreciated.
