US Galaxy Tab Wifi P1010 Gingerbread Guide
I put GB on the GT-P1010-CW16ARB from newegg US. Link. I got bootloops.
Was sad but I googled P1010 bootloop and people found a solution.
waqypaqy says to flash this rom to fix bootloop http://www.multiupload.com/KJO2KALU2O
Once I flashed this I was on a european froyo build. This allowed the Gingerbread build to be able to successfully flash without bootloop. I had no problems afterward. I dont think that the US build was made to handle the EURO builds.
