Hey all. There's a lot knowledgeable folks around here, so I thought I'd see if I can get some help on my problem. I've got a Galaxy Tab 10.1 Wifi, that I rooted about two months ago, using the instructions found here. Haven't done anything else to it, aside from installing a few run of the mill apps. It did auto-update a couple of times. Was working fine, now it just got stuck on this screen with a message: Code: ODIN3 Download Mode (Protocol v2.1) Reason: No Kernal Secure Mode: Secure Check Signature: Check Custom Binary Download: No (0 counts) Custom Binary: Samsung Official Waitting USB Cable... Downloading... Do not turn off target!! It comes to this screen after the Samsung title screen (not the animation) and a VERY quick screen with some red writing (goes by too fast to see what it says). I tried to follow the original instructions again. Put the tab in download mode (power + volume down), open Odin3, select the md5, and hit start. Get a FAIL with this message: Code: <OSM> Check MD5.. Do not unplug the cable.. <OSM> Please wait.. <OSM> recovery-cwm_220.127.116.11-sam-tab-10.1.tar.md5 is valid. <OSM> Checking MD5 finished Sucessfully.. <OSM> Leave CS.. <ID:0/004> Odin v.3 engine (ID:4).. <ID:0/004> File analysis.. <ID:0/004> SetupConnection.. <ID:0/004> Initialzation.. <ID:0/004> Get PIT for mapping.. <ID:0/004> Firmware update start.. <ID:0/004> recovery.img <ID:0/004> NAND Write Start!! <ID:0/004> <ID:0/004> Complete(Write) operation failed. <OSM> All threads completed. (succeed 0 / failed 1) The screen on the tab updates with this: Code: WritePArtition: Error to NvStorMgrFileWrite![err:0x30000] DownloadPartition_odin: Error to WritePartition![err:0x30000] Tegra_Nand_Write: Error to DownloadPartition_odin![err:0x30000] That's as far as I've gotten. I noticed the Re-Partition option is not checked in Odin3, and the errors on the tab have to do with partitions... but didn't want to do that if I could eff it up even more. Any direction on how to proceed? I'm also wondering if one of the auto-updates didn't muck up the works. Any advice would be great. Thanks everyone. TL;DR: Stuck in Download Mode, get errors on re-root.
