da quello che scrivi non è che sia facile capire dove eventualmente sbaglia. Comunque visto che sei con una JP5 ITV (come ero io prima di mettere la Darky's che è la ROM che Tatuato prende e traduce in ITA) ti consiglierei di seguire questa procedura:
Clean Guide
Requirements
- Working 3 Button Combo (VOLUME DOWN / VOLUME UP + HOME + POWER)
INSTRUCTIONS
This will guarantee that you don't get a black screen after the initial bootscreen and everything will work fine.
NOTE 1: I like to do things in a CLEAN WAY and HENCE I do a clean install everytime. This ensures proper testing and efficiency and has the least chance of failing. It only takes 5-10 mins extra to do everything the clean way. I do it this way because it has always worked for me. everyone has their own methods according to what they are most comfortable with. All I can guarantee is that if you follow my procedure your phone will boot up normally with Darky's ROM and you won't be stuck forever on the loadscreen with vibrations.
NOTE 2: It doesn't matter what ROM you have at the moment. This little tutorial applies to ALL current ROMS running on your SGS I9000
PROCEDURE:
1. disable all lagfixes/tweaks. if you have voodoo then goto the "Voodoo" folder on your internal sdcard. If the folder isn't there then just make it. Inside that folder make another folder called "disable lagfix".
2. REBOOT your phone. Wait for Voodoo lagfix to disable. you will hear a robot girl voice while it is doing it.
3. download Darky's ROM and ClockWorkMod (CWM) Recovery to your computer.
No need to rename the files.
4. connect your phone to your computer and copy Darky's ROM and the CWM 'update.zip' to your internal sdcard. DISCONNECT your phone from the computer
5. now download Stock XXJPU firmware to your computer. Password for extracting: samfirmware.com
6. if kies is open then close it. make sure your phone is disconnected from the computer.
7. now open Odin v1.3 Use 512 PIT file from the stock ROM that you downloaded. Use PDA file as PDA, MODEM file as PHONE, CSC file as CSC.
8. ENABLE "repartition" box in ODIN.
9. now boot your phone into download mode and then connect your phone to the computer. Once ODIN shows that your phone is connected press the START button in ODIN to flash. DO NOT DISCONNECT THE PHONE. DON'T DO ANYTHING. just let ODIN do everything automatically. Once stock XXJPU has been installed, your phone will reboot itself. when your phone has fully booted, disconnect it from the computer.
10. close ODIN and start it again. this time use CF-Root as PDA. leave everything else blank. make sure "re-partition" is DISABLED this time.
11. Boot your phone into download mode again and connect it to the computer. flash CF-root with ODIN.
12. once your phone has rebooted disconnect it from the computer and close ODIN.
13. install Root Explorer and go to your internal sdcard and delete the "Voodoo" folder.
14. now boot into recovery(2e) and apply update.zip to start CWM. You will need to do this twice for CWM to load.
15. in CWM do a factory reset, cache wipe and dalvik wipe. dalvik wipe can be found in advanced options. (again i'm doing all this to keep everything clean and safe)
16. install Darky's ROM with CWM.
17. reboot.
18. if you followed all steps properly you will hear a Robot Girl talking you through the reboot. The reboot will take 4-5 mins.
29. AND you're done! reboot again to make sure all settings have properly taken effect.
Hope that helps. ENJOY Darky's XXJPU ROM.

questa procedura è un pò più lunga ma ti garantisce un risultato al 100%. Inoltre non ti far spaventare dalla lunghezza visto che una volta letto tutto le operazioni da fare si fanno in max 10 minuti.
se hai qualche problema con l'inglese fammi sapere che nel caso ti traduco il tutto
@ALL
non sarebbe comunque il caso di mettere questa guida nel primo post visto che su questo forum girano molte più persone "alle prime armi" rispetto all'XDA forum ?
