I have an AT&T Nexus one that is rather flawless, except the bottom part of the screen seems to only work one out of 20 tries. It took me 20 swipes just to unlock the phone. Sometimes it takes more.

Samsung Captivate (AT&T)

I have a broken captivate, fell 5 floors down. Then I opened it apart to see that the screen was smashed in bits. So unscrewed everything, ripped out the screen apart from some sticky goo parts. Then realized that a mechanical engineer could not explore it further :) I will be more than happy to send the device to anyone if needed for further research.

I will indulge you with the Indulge

if you are still doing you project, with the broken phones and such i have a hard hard harder than hard never been abused other than intensively flashing it to its dark state. I have all that i read and viewed of the hows and whats to do to fix it! But im am at an impasse......so like my self i will donate it to discovery so that it will not have gone into dark rebellion for nothing.

@AdamOutler,

Is it possible to use this to fix the Nexus 7 from a hard brick state?

Doesn't it come down to somehow accessing the nand flash and at least getting a good bootloader.img back onboard?

Thanks

I don't know of anyone who software bricked their Nexus. I don't know if we have the NVidia SBK required to communicate with the N7.

    We now have the ability to make all devices with Hummingbird processors into "Super-Dev Phones". I just need a single dead board from each model to locate the proper modification. It can be water-damaged, broken, busted, cracked, smacked, set on fire, chewed on by your dog, dropped, thrown against a wall, or otherwise inoperable. I need a mainboard from each device to make this work.

    If you wish to donate a dead device, post here, send a PM, or email me at my username @gmail.com

    We can bring this modification to every device with the same processor, we just need to perform analysis before you can set up your device for bootloader development, or resurrect them from a hard-bricked state with nothing but software after a slight hardware mod.

    We need to locate the xOM5 pin on following devices before they can be modified into UnBrickable Super-Development devices:

    Just about anything with a Samsung processor in it.. There's so many
    devices. These are the most common ones we are targeting.


    Once I have received any of the above boards, I will attempt one of the following tricks to find out where the xOM5 resistor lies. Please understand that there is ALWAYS risk while working on electronics. I have done several of these sucessfully.

    Methods for locating modificaton
    1. Monitor memory locations in real-time while using the viewmem tool for changes to the OM registers. This only works on a rooted and working device. I can short high from behind a 10kohm pull-up resistor to a low value which is pulled down from a 100kOhm pull-down reistor. This will allow the high to counteract the low and a memory location can be monitored while performing this operation. This leaves the device totally operational and is the best way to perform this type of analysis, but is only accessible on some devices

    2. Using overlays and processor pinouts, I can trace out likely locations of the xOM5 resistor, make a modification, and watch the results from the SBL over UART. This leaves the device totally operational.

    3. Using relative positioning, I can pick a resistor, make a change and test for proper modifiction. This leaves the device totally operational.

    4. Using a multimeter, I can remove the processor from a device and trace out the pins manually. This method is only appropriate for a broken device.


    As an additional benefeit, we may be able to port the Nexus S bootloaders to the device, allowing for the latest version of Android to be ported easily to the device... After that, Ubuntu, Apple iOS, WP7, you name it...

    Let me get into some of the technical details here... If you're not technical, jump to the end.
    ----
    Pure and simple, this is a hardware exploit which allows direct upload of code to run on the S5PC110/Hummingbird/Cortex A8 platform. Samsung's chain of trust(CoT) model uses hardware to authenticate the Integrated Read-Only Memory (IROM), which authenticates the initial bootloader (IBL), which authenticates the Primitive Bootloader(PBL)... The IROM,IBL, and PBL are all loaded in IRAM, the PBL's job is to initialize Dynamic RAM(DRAM) and authenticate/load the Secondary bootloader(SBL AKA BL3), which loads a kernel, which loads the operating system you see on-screen.

    This is a two part hack. We've developed a hardware modification which allows USB download of code. We've also developed the Hummingbird Interceptor bootloader(HIBL) which intercepts the CoT and allows a second, unsigned download. The HIBL uses official code to handle authentication, which jumps to another memory location. It's this memory location where we place our exploit. Our exploit reuses the same code that downloads the HIBL to IRAM, but it initializes DRAM which means you can directly upload a SBL(the final bootloader) to DRAM.

    So once again.. really quick... We use a hardware mod to download Rebellos' HIBL, which violates the Chain of Trust, exploits a memory jump and allows unsigned code to run on the processor. All this means you can revive a dead phone easily or try out other operating systems and debug easily, regardless of signature checking on the device.
    ---------

    The first part is the hardware modification so things can be tested without risk. Please help out if you have a dead device. I can make constructive use of it, or you can PM me for instructions. Either way, that old junked device you have can help out millions of people.

    Added Fascinate to the UnBrickable List. http://forum.xda-developers.com/showthread.php?t=1288162

    The owner of RootzWiki gave me a Fascinate yesterday at the Big Android BBQ. I was able to locate the modification, gather together firmware and make an entire solution available within 24 hours.

    This is a worlds first for the Fascinate. Never before has there been a method of unbricking a Fascinate. I didn't even have to destroy it! I'm pretty happy about that.

    Yes, it's incredible that a device that sold more than 14 millions units still doesn't have this feature... but in the other hand, if my Galaxy S get bricked, I'd try to repair it, don't you think? :D
    A donation could be better... We donate a small amount of money, the devs buy a Galaxy S (bricked, new, whatever) and they start working :cool:
    I'm also looking forward to try WP7!

    I could manage that if you wanted to start a donation fund... just ensure everyone who donates posts in the thread, and mentions that they donated. and I will acknoledge that I received the money so that everyone knows there's nothing shadey going on. Then I would keep everyone updated so that they know where their money is going. I'm not too keen on "asking for money", however if you wanted to start that thread, then I'll play along and buy a busted i9000 from e-bay.

    Or you could simply send me a device, and I can put it back together, send it back, then you can say.. OMG WHT HAPPND?!?! The processor came off! lol... i'm not recommending this... but hey.. it might work.

    So maybe u can run iOS on samsung, or WP7 on iPhone?
    Or i misunderstand?

    Let me break this down... This modification means you can NEVER brick your phone. You have to physically destroy it. There's no firmware which can ruin the phone. You simply plug it in and run this tool..
    2s78isk.png

    This tool is still a work in progress. It requires a Linux machine (or linux Virtual machine) in order to run. However, it works, and it works well. This tool will work for:
    SGH-i897
    SGH-i896
    SGH-i9000
    SGH-i9010
    SGH-i997
    GT-P1000
    T959... We will need to write another tool for other devices.

    What this allows is for debugging of entire operating systems without any risk. For example, I installed BADA Bootloaders to my device last night with one of the guys from the BadaDroid project (they're working on porting Android to Bada). My device totally crapped when it saw that firmware, but it gave detailed logging messages about GPIOs. It would be possible to take that firmware and rewrite it to work with our devices, and it basically eliminates that "what if I screw something up" $600 barrier that prevents porting of other operating systems to our devices.

    After I flashed Bada bootloaders with the tool above, I simply pulled the battery out, put it back in, connected to USB, used the tool above and it put my phone back into Odin download mode, at which point I reflashed the device.

    We need to spread this mod to all the devices. Currently we have SGH-i897 mod done.
