Are my ideas below likely to work in restoring my phone?
I've been compiling information for UnBrickable mod on the various versions of the Galaxy S2 device. This generation is by-far the most decentralized "model" I've ever heard of. Some of the devices contain Exynos processors, some Qualcomm and others have OMAP.
We've conducted research on this generation of device in the following threads:

But you're here for the Galaxy S2 Hack Pack. This Hack Pack is designed to help out those looking for information on modifying and/or repairing their expensive devices. This package contains:
Please let me know if there's anything I should add to this pack.
I have a bricked (auto checked repartition during cwm reflash type brick) grrrSGH-I727R can only be seen via QPST in Download mode. I have been reading a heck of a lot about this device and have managed to accrue a vast amount of resources and information on this device.
I have had some success in using QPST files for a Galaxy note I7I7 (I will update with precice information once I can sort it all out, from downloaded drivers to specific information gathered, etc...). I Used QPST to load a hex file using eMMC Software Download App. This got the phones full SDCARD internal and user to show up on the computer. But QH USB modem 8000 (win native support) driver would not load, which stopped QPST in its tracks. Although I think that I am grateful for that not working as the next step would have been flashing my device with Galaxy Note firmware etc...
Next I used a Windows based partitioning tool to recover the lost partitions but the recovery did not stick. So I am using another tool to see if that works. I still cannot see the phone via ODIN or Heimdall etc... so no luck there with the "soft"unbrickables.
But if I could create a working set of files that are similar but device specific of cource and compete with hex files like I got for the galaxy Note plus the correct drivers. The phone would then as it was before the changing QPST put it through i.e., the added sight of the other USB devices in device manager. I don't see why this would not unbrick the phone.
But I have only ever been able to find firmware with hex files and other files for flashing low level once and that was for the Galaxy Note as mentioned. I have access to another unbricked totally stock Galaxy S2 which I can use to create these files. I need help so that I am not just guessing as to what I'm supposed to do based on other devices and praying I don't brick the other phone too. I am going to create a disk image of the device before the partitioning repair so that I can try to use Linux to recover the partitions some of which are ext3, then I won't have to risk another brick.
I know that the system is basically there as the information I get back lists all the mmcblk's almost exactly as the ODIN tar says it's mount points are for them and relatively the right amount of data is still there too.
Once the image has been created I am sure I can figure out a way to rebuild the partitions and files that are on them, At least I hope so before QPSTs hell freezes over. I'm not all that knowledgeable on data recovery with linux. I am still at a stage of commandline use where breaking the system beyond my ability to repair it other than a reinstall is a possibility.
I am learning all this by myself and via sites like yours and now a couple others based on the QPST knowledge I am getting. Anywho I'm rambling now. Please can someone get back to me with what I can try next or should be trying instead?
