Thank you very much.
Congratulation and many thanx for Pics of RD-PQ... :cool:

1.
Now I know is no bul.s.. that RD-PQ is like Live Demo Unit I9300x...

2.
If I look at PCB, I can see I8800... :D

3.
If I am not blind... I think you used eMMC direct...
As JTAG is in my opinion disabled/secured...

Anyway.
Many thanx.

So I will proceed to go the other direction...
From I9300x to Tizen on S3... :D

Best Regards


Thanks,

Yes you are correct. RD-PQ is like the live demo unit.

Yes, the model i have is the GT-i8800, this is the model for the circulating Tizen redwood.

I use JTAG to erase the eMMC and put new boot and ROM. The idea of JTAG came to me when i read one of the comments that he flash using ODIN and and nothing happens, JTAG erased everything and reflash it with a new Boot and ROM's.

After using JTAG, i got stuck on the Samsung Galaxy SIII GT-I9300 screen. I put it on download mode and I relash the PDA with ODIN. After reflashing with ODIN, i got an invalid argument error, go to recovery mode, then make factory default, wipe cache etc.

Reboot,.

After it boots up, i got a Default Service IMEI 004xxxxxxxxxxxx/xx

Rebuild it with another tools.

Flash Root using recovery.

Reboot.

The eMMC of the S3 is the Same as the RD-PQ.

If somebody is alive with RD-PQ... :D

Please, I need some answers...

My study leads to this "knowledge" on I9300:
http://forum.xda-developers.com/showpost.php?p=59479128&postcount=13

Short summary...
I9300 has only "1 Bootloader" aka sboot.bin...
And RD-PQ has "2 BootloaderS"... sboot.bin AND uboot:
Code:
s-boot-mmc.bin
u-boot-mmc.bin

For uboot you need other Key combination for Download...

Question/theory...
sboot on RD-PQ is different... 200 KB instead 800 KB...
But if I did not mistake or some Security thingie... my tests allow writing sboot from RD-PQ to my I9300...
And Android runs and also Odin work with s-boot-mmc.bin...

Here Pic how DL Mode looks on RD-PQ...
http://forum.xda-developers.com/showpost.php?p=59544427&postcount=17

1.
What happens if RD-PQ user press Volume - and Home and Power, like I9300 have to do for Download Mode?
:confused:

2.
Someone tested RD-PQ with DL Mode JIG?
:confused:

I mean this USB Resistor thingie... to reach DL mode without pressing any keys...

3.
Theory...
For RD-PQ device to run Android. sboot from I9300 could be enough...

DANGER! WARNING!
You could kill RD-PQ...

Test in theory...
Take sboot.bin from I9300... good question which one... maybe oldest XXALE8...
Rename into s-boot-mmc.bin...
Take any Tizen Boot package for RD-PQ... and replace s-boot-mmc.bin...
Create valid TAR...
Flash with lthor

Again, this could kill RD-PQ or do other trouble...

You could do own reseach with this info:
http://forum.xda-developers.com/showpost.php?p=55514573&postcount=36

BTW.
4.
Can RD-PQ dump sboot?

Something like this:
Code:
dd if=/dev/mmcblk0p1 of=/sdcard/sboot.bin

Are these 8 MB empty? Only 000000 ... then same result like I9300...

But on I9300 you can write... see this:

    Someone can help me?
    thanks


    You have been helped but choose to ignore the advice given .

    I suggest if you need help then you lack knowledge to try such a firmware change .

    you can get like ten grand for that, you sure?

    To answer the question: flash any ROM from here as long as you are completely sure it's a i9300.
    You can't have Android and Tizen side by side, and your Tizen which gives all the value to the phone will be gone if you flash Android. Not sure if a nandroid would work

    First ever (maybe) Tizen RD-PQ Device converted into Android S3

    I dont know if i'm allowed to post everything in here, since i use 3rd party equipment and procedure. Proof?

    I strongly discourage the convertion. I just did this for educational purposes to answer all the question on whether it can be converted or flashed or not.

    I AM NOT RESPONSIBLE FOR ANYTHING ARISING OUT OF THIS PROCEDURE.

    maybe you will ask or question my background ( 16Post only)..well, i am working on my mobile shop since 1998.

    I did not replace any parts, i just add, I replace the missing parts using parts from a dead S3.

    AND NO. I DID NOT REPLACE THE BOARD EITHER.











    If mods will allow, i can post the BRIEF procedure which i did.

    it does not involve ODIN, (although ODIN is use on the later part), it is not the main software. Not even thor downloader. AND It's not EASY.

    JTAG is the Key.



    AND YES, I SUCCEED.



    Please dont send PM as i dont go online all the time. And this is not a joke either. THIS IS REAL.

    RD-PQ board Pictures and s3 Board

    Looking at the board of the RD-PQ and comparing it to the S3, all is the same, except for the missing parts which i highlighted on the pictures below. The eMMC is the same. i came up with an idea and will test it tomorrow. will keep this updated.
