Heimdall One Click Unbrick Galaxy S2

Just succeeded re-stocking Gingerbread to an unmodified GT-P1000XXJID (Froyo) after a week of trial-and-error;-) This is what I came across: When trying to flash the Galaxy Tab with the Stock Gingerbread Kernel (Overcome GB-Stock-Safe-v5 or official P1000XXJQ1/-JPZ), heimdall 1.3.2 gives an error after uploading the kernel: Uploading KERNEL 100% ERROR: Failed to confirm end of file transfer sequence! KERNEL upload failed!

I experienced this a few days ago on my Ubuntu 11.10 Oneiric system, using the heimdall 1.3.2 oneiric version from the. I then thought that maybe the oneiric version of libusb-1.0-0 could be a little too old, so I ventured the still outstanding release upgrade to 12.04 Precise.

Jul 6, 2011 - A developer has come up with a one-click unbrick tool for Samsung android devices that use ODIN for flashing a file. Here is guide to unbrick.

But today I found out that this would not have been the problem - flashing the kernel to the device still brought up the error. I downloaded two other versions of a stock Gingerbread ROM, to confirm via checksum that the zImage file I was trying to flash was sane - it was.

Lastly, I remembered someone on the net and in another context suggesting to downgrade heimdall to see if a former version would work. I did not consider that in the first place, because I had also read (here) that the 1.3.1 version still had problems with the MOVINAND and HIDDEN partitions.

But having arrived at my last resort before giving up and attempting to restore Froyo, I gave it a try (apt-get purged heimdall from the PPA repo and the repo itself, d'loaded the 1.3.1 deb and dpkg-i'd it). And yes, flashing (only) the kernel works with 1.3.1. And no, it does not work with the 1.3.2-deb either, I cross-tested this. Uzli krepleniya keramogranita v dwg.

So I ended up flashing everything except the kernel with the 1.3.2 version installed, then downgraded to 1.3.1 and flashed the kernel. Rebooted, trepidant for a few long minutes, but was then presented with the Gingerbread Setup Screen. OT, but I post here instead of e-mailing, so my answer is visible publicly.: Sorry I could not be of help. Flashing the GT is not necessarily an easy thing. It took me about a week to get ICS running on mine and I didn't re-try since.

Additionally, there are several versions of the device (some of them non-flashable), and I had to try out several ROMs, Kernels and such. You should try to read up on the topic on the 'net again and try to re-stock your Tab whenever you're stuck before trying another approach. Most flashing tutorials recommend re-stocking first. There are also several good hints out there on how to revitalize a seemingly 'bricked' Tab.
