Well fellas, I have a priliminary/test custom CWM recovery image for our device, that should be flashable by ODIN.

I have not flashed it yet, planning on doing it tomarow morning.

In the event that something goes awry, I don't want to be stressing all night long about it

I will keep you all posted!

Nice work. If it gets botched as long as you can get into download mode just flash back stock via Odin. Cwm could break the hard key recovery I think it but you could use adb commands in that case (I think).

Well round one didn't work out, ODIN hung at the point it actually tried to write the recovery.img from the .tar over.

Eventually I powered down the tablet, which it immediately booted back up into "Firmware Update Failed, please connect KIES in recovery mode".

I decided for the hell of it to try re-flashing the OC kernel to it at this point, even though what I attempted to flashed had nothing to do with the the kernel.

It successfully flashed over, and my tab booted up normally.

I think what happened there is the tab saw a failed flash, so it decided to force download recovery mode till something was flashed, even though the failed file likely didn't write anything at all to the filesystem.

Then when it saw a successful flash, it decided, "Ok we can boot up normally now"

All just guesses, but anyhow there's your update!

We are working on some other plans of attack now.

Progress is being made, I think were getting close, the sgh-i957 is kind of un standard when it comes to how its boot and recovery partitions are setup and utilized, so most of the trouble has been in figuring that bit out.

Progress is slower since a dev doesn't own it but at least we are getting somewhere. The closer we are to finding the differences from the skyrocket the easier ports may be for ics.

Well I seem to have pretty thoughly bricked my poor tab.

Without going into to much detail, I should be more careful with .pit files and ODIN heh...

The tab itself appears totally dead, no boot, no back light, no matter how long you hold the power button / vol button combos.

When you plug it into a computer, it shows up as QHSUSB_DLOAD, and cannot find a driver.

ODIN and HEMIDALL don't see it at all.

I managed to find a QHSUSB_DLOAD driver of some sort, and using QPST was able to see that it was a com port, but I can't do anything past that.

Any of the tools in QPST say they cannot be used because the device is in download mode.


Anyways, pretty sure its gonna have to go to samsung to be fixed.

Which blows, because were pretty sure our next test will be successful, but of course who knows

I was litterally 1 day inside of my 30 day return window at AT&T, so I decided to run down to the local store where I bought it, and was able to exchange it for a working one.

"I was just watching some netflix and it went totally black all the sudden! Now it won't do anything at all!"

A few mins later and I am back in action.


However I don't really want to be bringing another one back to them any time soon
