Default [CDMA][SPRINT][VZW]P100/P800 GTab Dev Platform AKA UnBrickable Mod && Resurrection

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. Flux
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.
1. Remove the two(2) screw covers on the bottom of the unit. Remove two(2) #1 tri-blade screws

2. separate the top cover from the bottom cover

3. Remove eight(8) screws and four(4) connectors securing the board to the unit.


4. Remove four(4) screws securing the EMF shield to the board


5. 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.



6. *OPTIONALLY* hook up UART connections for kernel and/or bootloader debugging at the locations shown in the picture above

7. 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


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 3.


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:



3. 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. Run Heimdall One-Click to flash firmware on your device.
http://forum.xda-developers.com/show....php?t=1341666


5. 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.

You got it working... Great work.

Could you perhaps expand a little more? Such as stating things to avoid to prevent it from bricking? For instance before this mod should a power failure occur when flashing via ODIN = brick. Once this mod is performed. Are there any similar issues?
Most people aren't idiots, but it only takes one to ruin it for the rest of us.

You don't need to worry about it. Before your device even starts up, the first thing it does is go into UnBrickable Debug mode and you can boot it into Download Mode from USB. There is no need to worry about anything at all after this. No known firmware can harm your device. You can flash Bada, WP7, just about any bootloader you want, see if it bricks your device... If it does, then just flash back.

If you want, you can flash a Justin Beiber MP3 as a Secondary Bootloader and a LOLCat as a primitive bootloader... You can still recover your device. Just pull the battery out, insert the battery, plug into USB on the computer and click the download mode button.

I am very tempted to do the mod just because I can. Much easier than doing it to my Epic (since I need a working phone) which Adam had added to the list of unbrickables as well

Once again great job on all the unbrickables on the list!

Adam what about the SPH-P100 SPRINT CDMA model? If it does would it be possible to flash the gsm model version firmware and software onto it? I do not have a sprint account and will not be so I only use it via wifi. Thanks

Yes' but I had problems with the modem, so I did not include it. Check the modem thread for modems.

I just did this mod on my hard bricked vzw galaxy tab, and it saved the hard bricked paper weight to a fully functional tab again. This is definatly a must have mod..
Galaxy S5-TMO - NE6 Base - Rooted- No Custom Recovery Yet
Galaxy S4 ATT- MDB Base - Rooted-CWM Recovery- Deadly Venom v2.2.5 KitKat 4.4.2- Non_SafeStrap- cCc Themed
Dell Venue 8.1 Pro Tablet - Windows 8 - WiFi
Galaxy Tab VZW -- Orignal - Unbrickable Mod- JB 4.2.2 GSM/CDMA AOKP SGT7 by Stimpzor still going.
