A good challenge for the I780 Specialists

I bet that the solution would be very easy :):):)

All the best to you

There are quite a number of answers posted. EFN had already explained too many times. He had said that the bootloader works fine, that's a good start.

Just get the necessary rom from EFN thread, phone rom PUHE1 and the pda rom DXHE1. There is even a tutorial on this in EFN thread (1st post).

[hellboss]

g00ndu can you please help find the thread/topic where EFN explaines it, i'm having a hard time finding it!
thank you

I think he is talking about this:

download Flashing Guide Tutorial - at the bottom of the 1st post

[hellboss]

did exactly as said in the tutorial....
nothing... it seems that the eboot is always the same.....
i don't know what else to do!

[hellboss]

g00ndu i can't find the thread you are talking about....
where does EFN talks about the bootloader or a problem like mine??
could you please help me!
thanks!

Okay step by step:

Did you downloaded the russian rom i780PUHE1 (eboot+phone+pda)?
Did you downloaded the i780DXHE1 (pda only)?

Follow the tutorial, assuming step 1 to 4 had already been done.

(5) Launch Mirage updater. Select MIRAGE LV image as the profile
(6) Select EBOOT+PDA+PHONE and select the extracted RUSSIAN .img file
(7) Click on DETECT
(8) Switch on the phone while holding the ENTER and FUNCTION buttons (ALT BUTTON)
(9) After the system DETECT message appears, connect the phone via USB to your PC
(10) Wait until the image is written.

Before flashing to the DXHE1 rom first, please try to boot up and see if it works. If it is successful, you will see plenty of gibberish characters. This is EXPECTED, as the rom is russian.
If it doesn't boot up, then I am sorry I won't be able to help you.

Try the above first. Point to note is to choose eboot+phone+pda. Always press detect first before going through the enter+function+power on process.

If it works, please let me know.

g00ndu, thank you very much, but i already done that several times step by step....
but, unfortunately it stays the same....when i power it on it turns on the backlight but the screen remains black and nothing happens...
but thank you very much anyway!

[g00ndu]

hellboss, I'm sorry about your device. Perhaps it might be a hardware issue. I'm not sure.

While the device may have a black screen, you could try to see if the LED lights work, whether there is a sound after the system boot up. These are important clues to see if it is really hardware issue.

Once again, I wish you could find a solution to your problem. :(

Hi, i would like to know if it is possible to discover which ROM is installed in the equipment... I mean, the samsung doens't start i can only go into emergency mode,,, is it possible through the pc to discover which ROM is installed on it??

thank you!

I'm not really sure, but have you try to dump your rom using pdocread, one of the itsutilsbin tools? Meaning get the Part00, Part01 and Part02 raw files which is your rom dump?

[dogmood]

If i were you I will try most official rom to rescue the device first. like i780XHC4 that one has all three (healthy and normal) parts.

[hellboss]

dogmood i already tried.... but still nothing...
g00ndu , to dump the ROM don't i need to change some values on some key at the pocket pc registry?? if so i can't because the pda doens't start....

P.S-the first time i flashed it i did it on a pc with windows xp but all the time the process was incomplete and i need to turn off the phone and restart the phone, and at the second time was succesful, now i'm doing it on a virtual machine running windows xp pro sp2,,,,, can my problem be related to that??

thank you!

I use a VM for the flashing myself, so this shouldnt cause problems.

[EFN]

If flashing the official rom (EBOOT & Phone & PDA) doesnt work for u then you have to consider the fact that your i780 busted on the hardware level.

The best thing to do now is to claim for warranty and make sure u sent them beack with official rom in your phone (HC4)

[hellboss]

Hi EFN,
well I've considered that, and I think that my next move is going to be warranty
but unfortunately the ROM that came with the PDA was not the DXHC4, i bought my samsung in Portugal.
my problem now is that the PDA became dead when i flashed it with the DXHC4 eboot, and now that i can't flash any other ROM i can't put the original ROM, which i have a dump, on it....
so i think that is not going to be accepted on warranty....
honestly i can't discover what went wrong.... I followed every single step of the tutorial to revive a dead i780....

thanks!


P.S-> EFN, I'm a great admirer of your work (samsung i780 ROMs), unfortunately I'm not going to be able to try them......but... anyway keep up the good work!

[EFN]

I believe for as long as the rom on your i780 is an official one (regardless of version), Samsung will honor the warranty. You have to try to know. And of course dont tell them that you have been messing up with flashing this and that

[hellboss]

well i think so, if the rom is an official one they will honor the warranty...
that's the why of my question about a way to know the version of the ROM installed on the PDA, but i haven't discover anything...
i guess will just try my luck and send it to warranty!

thanks!
