I did that before posting it worked, that was part of my confirmation

UART is pin 20 (RX) and 21 (TX) on the docking port, we have actually had this for a while, The jtag port is different on this device, it is along the edge of the board and coated so you need to scrape them back to get access.

Can this be broken out? Can you run UART and USB at the same time? This is required for developing bootloaders and porting things like Linux to the device.

well linux has already been ported to the device, just FYI

but yes, USB and UART can be used simultaneously as the USB pins are not the same as the UART pins, one of the other users here found a Chinese clone cable that was easy for it, as in the standard connector the pins are NC, so he got 2 clone cables and connected up all the pieces to make one super cable,

I did it slightly different, I shaved the keying off the edge of a clone iPhone cable and did the similar thing with it, but I don't have UART on mine, I am probing around inside to find a more permanent wires out the side UART solution

As one final test I flashed an unsigned boot into Sbl position with GB IPL+PBL which requires Sbl to be signed.

Code:
?1

   Samsung Primitive Bootloader (PBL) v3.0

-----------------------------------------------------------

ERROR.. Bootable SBL doesn't exist ..

was the output over UART, pushed the resurrector download mode button, then reflashed Sbl with heimdall and it kicked back into life,

great success :D

Is there a link with instructions for heimdall? I am trying to put together a one-click. I don't own a Galaxy tab. I need pit, bootloaders and whatever else.

no, but there are links to them on this forum, or FUS downloader

just a little bit of extra that I forgot to mention, Grounded pad is on the side facing the edge of the PCB, and the non-grounded side, the side we want, is the edge facing the SOC

I would appreciate it if someone would take the time to:

1. turn the device off
2. run Ultimate UnBrickable Resurrector (Galaxy Edition)
3. run Heimdall One-Click to return the device to stock.

This will give me enough to finish the Galaxy Tab project.

is there any way to make it temp mod which can be used to recover a bricked device using unbrickable mod and then restoring it is it was before

can it be achived using only wires or external resistors rather than making the device permanently unbrickable by removing the resistor . most of the devs may not be so comfortable with a soldering gun

and last but not the least i appreciate the effort and time your team put into this mod. thank you

No there's no other ways. Your other option is to pay $50 for JTAG or $200 for a JTAG box. These methods require a lot more soldering and special tools.

This is easy compared to the other methods. Its the DIY method. I charge $30+ shipping for this mod. Its the best brick recovery available and it turns your device into a development board.

Thanks for the props.

I have managed to perform this mod, it did flash and i managed to enter recovery. However due to my bad soldering its not booting, does anyone know of an alternative xom5 point (non grounded) that i can use? Ill upload pictures for relative location of resistors if needed tonight.

it may not be your soldering, I thought this was the problem at first, but hooked up to my computer it will not boot, plug it in to the wallcharger or unplug it, and hold down the power button for a few seconds, the touch strip will light up when you have held the power button long enough.

Helo, this is my first post here, and the reason for it is that I bricked my NEW galaxy tab gt-p1010 trying to upgrade it to android 2.3..
Since I have some experience in electronic, maybe I will try to mod it to unbrickable mod, if it is possible.. hope with your help.. and maybe that help someone else...
here is the main board with cpu..
And I wonder where the resistors are???
markings on CPU are:
SAMSUNG 107
KAT007015-ARTT

!!!Help!!!

    First Off, Huge thanks to F50+ This man sacrificed his tab to locate these resistors.

    introduction
    I'm not kidding when I say UnBrickable. Modifying the OM pins means you can boot from USB, UART or MMC. This makes the device quite UNBRICKABLE. There is nothing you can do software wise to prevent the device from booting into this mode. We are communicating with the unrewritable, efused IROM on the processor. It's the thing that makes the system on a chip into a "system on a chip".I am here now to tell you how to turn your Samsung P1000 into a KIT-S5PC110 development board. The KIT-S5PC110 development board is the platform used to develop our phones. There are some differences between this mod and the official development platform. The S5PC110 has a removable internal SDCard and no touchscreen.

    Why would you want to do this? When you plug in the battery and connect it to the computer in "off" mode, it will become an S5PC110 board awaiting download of a program to run. This occurs long before anything like software or firmware enters the processor. This is the IROM of the device awaiting commands or a power on signal.

    How could it possibly be better then JTAG? Let's count the ways....
    1. The only part required is a wire.
    2. No shipping time.
    3. No cost for a box to interface the computer.
    4. Permanent.
    5. Can be done as a preventive measure.
    6. Gives the ability to test new Bootloaders temporarily.
    7. Allows development of the entire system.
    8. Removes worry about flashing and acts as a backup.

    After performing this mod:
    Remove the battery, replace the battery, your phone will connect to the computer via USB and await commands. Otherwise it will pretty much act like a P1000. See the Special Instructions section.

    Part 1:Hardware Modification

    You will need:
    1. Get someone who knows what they're doing with a soldering iron. If they don't know what flux is, then they don't know what they're doing. You can send me a PM(or email my username@gmail.com) or Connexion2005(aka MobileTechVideos.com).
    2. Soldering iron - make sure it's sharp, if it's not sharp, then sharpen it, flux it and retin it.
    3. fFux
    4. Solder
    5. Tweezers
    6. A relay (possibly- for the wire within to use as a bridge)
    7. A #1 tri-blade driver


    performing the modification:
    1. tear apart your Galaxy Tab... Make sure to take out your SIM and external SDCard before you do this.
    1A. Remove the screws.
    1B. Separate the top case from the bottom case

    ****VIDEO OR PICTURES NEEDED*****

    2. Perform the mod as follows: remove the xOM5 resistor and jumper the non-grounded pad of xOM5 to the same side of xOM0 or xOM3.

    1zdxlpf.jpg


    I will be able to give more detail after I have performed this modification myself.

    3. reassemble the Tab.


    Special Instructions

    • This replaces the battery charging sequence. The normal battery charging sequence can be activated by holding power for 4 seconds, then plugging in the device, or you can use an authentic Samsung Charging Cable for charging the battery
    • To turn on the device, and operate in normal mode, you must hold the power button for 5 seconds.

    Part 2: Software Based Resurrection
    6o1rbb.png



    The entire software resurrection can be summed up like this

    Here is a Galaxy Tab specific video

    Unbricking:
    1. Apply UnBrickable Mod to your device: see Hardware Modification section
    2. Run The Ultimate UnBrickable Resurrector. You can find the Resurrector here in our SVN repository http://code.google.com/p/hummingbird-hibl/downloads/list

    When you see this image you are in S5PC110 SEC SoC mode. When you see this mode you must proceed to step 2.
    k9cdgy.png


    If it will only show this image, then you have not performed the modification correctly, or you have a hardware problem.
    2qa4xas.png


    If it shows this, regardless of what's on your screen, you're in download mode. Proceded to step 3.
    730xm0.png



    2. Click the Download Mode button (then click the one next to it). I find it's easiest to click Download Mode, type a password, plug in the device, then press enter.

    3. Run Heimdall One-Click to flash firmware on your device. http://xdaforums.com/showthread.php?t=1323527
    mmpxmv.png


    4. repeat steps 2 and 3 with bootloader flashing enabled (Heimdall One-Click has a safety mechanism which requires you to flash once before flashing bootloaders).


    Conclusion

    Congratulations. You now have a device which works like a KIT-S5PC110 with an OM Value of 29. Now get to developing some serious custom software.

    hi guys!!

    hi guys!

    I would help you! :)

    the theory:

    20syu0n.png


    this is the final work!

    20120331113842.jpg


    senzatitolo2n.jpg



    This Debrickable mod (and mod Resurrection) works fine!

    what you need:

    1. a good friend (thanks Ivan DZ)
    2. great hands... (or friend's ones!)
    3. a tuning wire like this (enamelled copper coil)... thinner may be better but warm deforme it faster

    20120331125715.jpg


    4. remove the resistor xOM5
    5. bridge xOM5 to xOM0
    6. then mount your G Tab
    7. run the Ultimate UnBrickable Resurrector using Ubuntu
    8. connect G Tab to pc
    9. in UUBR appears "S5PC111 detect"
    10. click "Perform Resurection" in few seconds your Tab is in Download Mode (in pc's software appear the usual pic "download mode" that appear also in Android Devices, the Android that works in yellow, BUT in Tab it may not appear, in mine only the flash turned on and the screen was off!
    11. now your Tab is in Download Mode! Do not disconnect the Tab! The Download Mode is supported by software, if you disconnect the Tab it lost the Download Mode!
    12. run Heimdall One-Click
    13. click "Flash"
    14. re do points 10-13 until Heimdall One Click allow to check "Flash Bootloader"!
    15. check "Flash Bootloader"... wait...
    16. Here you are your resurrected TAB !!!! (it's running stock GB Rom!)



    special thanks to AdamOutler
    and to Ivan DZ!

    This link and the HeimdallOneClick link redirect to github, what do I do with the zip to get HeimdallOneClick running?

    Here it comes. You are welcome.
    The github sources aren't very usable for mere humans :)
