[GSM] P1000 GTab Dev Platform AKA UnBrickable Mod And Software Resurection
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.
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.
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...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.
If it will only show this image, then you have not performed the modification correctly, or you have a hardware problem.
If it shows this, regardless of what's on your screen, you're in download mode. Proceded to step 3.
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.
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.

Yeah this is a genius idea for our galaxy tabs. With this, I no longer have to worry about bricking my device via odin because of my ****ty faulty HP laptop. (it happened once and i had to send it overseas for warranty repairs, 2 months w/o my tab )
Most people aren't idiots, but it only takes one to ruin it for the rest of us.

I still need to prove it works.

Its way too early for that... save that for the how-to thread.

Looking forward to trying this on my tab. You mentioned firmware would need to be made,I assume stock boot loaders could be used right away?how do we know which is grounded pad? What is the relay for?

Until I'm able to actually perform this mod on a device, I can't tell you anything. I don't know any more than what's in the first post.
