You will need some tools:
SPLASH SCREEN CHANGER
NBFTYPHOONTOOL V0.4
UPDATE SP5 Of IMATE
WINHEX (the version demo is enough)
WINRAR (the version demo is enough)

The update of the ROM modifies only the "bootscreen". You do not lose anything else with your current configuration – i.e. the update modifies only the part "SPLASH.nb" - all the rest stays the same on your phone.

Bear in mind, the tools used in this tutorial can also be used for "heavy" modifications to your phone, hence it is advisable to strictly respect the method below under risk of wrecking your phone.
Steve57 and Mlab cannot be held responsible for an unspecified deterioration of operation of your phone.
You are strongly advised to proceed to flash your smartphone if you understand the actions/implications generated by this tutorial.

Beginning of the tutorial:

1. Download from i-mate the WWE ROM for your SP5/SP5m (e.g. i-mate_SP5_WWE_1.5.331.4.exe). Extract the .exe file using winrar like below. NOTE: if your winrar does not directly propose to decompress the file, make a copy of the file and rename it <filename>.rar first and then extract/ decompress it.



2. From the decompressed contents of the .exe file, find NK.NBF and open it using typhoon NBF tool. Right-click on the line "splash screen" then click on "dump decrypted" then save the file splash screen.n_b where you wish it.



3. Now we will prepare your image using tool SPLASH SCREEN TO CHANGE. Click on "Load..." then select the image desired, and then click on "save.nb" and save the file with the extension .nb (e.g. “bootscreen.nb”) and close the program.



4. Launch WINHEX and open your file "bootscreen.nb" then the file "splash_screen.n_b" obtained with NBFTYPHOONTOOL.
In the Splash_screen.n_b window highlight using the mouse like below, the part of “offset 00” with the offset 0000001D, then key CTRL+C to copy.



5. Switch to the window “bootscreen.nb” then key F6, choose "editable mode". Now make sure the cursor is located at offset 00 and key "CTRL+V" to paste, see below.




6. In the window “Splash Screen.n_b” go to the offset 0002581E then right- click and select "beginning of block"



7. In the same window go to the bottom to last offset "0002FFFF" then a right- click "end of block". Then copy (by keying CTRL+C)



8. Switch to the window "bootscreen.nb" and paste the block to the offset 0002581E (CTRL+V). Before saving your modified file check its size. The file must be 196 608 bytes exactly. If it is, save your file then exit WINHEX. The hardest part is done. Be brave - almost finished!



9. Now we will create the final file for the update with the tool NB2NBF V.02. For that we need to fill-in various necessary information like below. Tick/check “File #1” then browse to your file "bootscreen.nb" created with winhex..



10. Finally switch to the file "i-mate_SP5_WWE_1.5.331.4" which you obtained by decompressing the update, then place in there (add to the archive), the file "NK.NBF" that you have just created with NB2NBF. If you named it nk.nbf it will overwrite the original. Launch the update (ROMUpdateUtility.exe) and follow the instructions.



The update takes less than a minute then the telephone will start again with your new bootscreen!!!
