Troubleshooting sendmsg failed? Bad luck. Fixed vold? with Gingerbreak

[the_maplebar]

I just spent 4 hours running gingerbreak 6 times getting the message

sendmsg() failed

and ending with

Bad luck. Fixed vold?

I finally got it working and want to share what I did and see if anyone else has solutions for this problem. First of all I'm assuming you have the adb shell working, can connect to your phone, copied all of the files to your phone and are able to run gingerbreak. After reading through dozens of pages from the rooting thread I see that lot's of people are getting the sendmsg failed output, but there is not a lot of specific information on fixing this. So the steps you should take if you have this problem are:

1. ALWAYS restart your phone so you have a clean boot before each attempt to root.
2. If it doesn't work the first time, power off, pull the batter and try again. Many people have gingerbreak work after 2 or 3 tries
3. While gingerbreak is running, Pull the SD card out, wait a few seconds for the SD card removed message then put it back in. (This is how I got it to work on the 6th try)
4. Format the SD card or try another SD card
5. Try the Gingersnap rooting method, this is a wrapper around gingerbreak but may work. (Has anyone used successfully used gingersnap when they were having this problem with gingerbreak?)
6. Remove your SD card or use an empty SD card (just found this in the readme from the programmers of gingerbreak)

If you have other solutions for getting gingerbreak to work after repeated failures please post them here.

How about gingersnap? Also it goes thru a sequence of mounting and unmountng when u do this process normally... just a restart of the cell is needed... or gingersnap like I mentioned

gingersnap may work in this case but requires .Net and Visua C++, I'm using linux so wanted to get this working from the adb shell.

I tried restarting the phone, and that is my first 2 suggestions, but I restarted 6 times before finally getting gingerbreak to run successfully.

I also saw a gingerbreak.apk at xda-developers forum, but that has a warning that some people have had their SD cards formatted during the process. Part of the reason I'm rooting is to do a complete backup.

why not copy the contents of your SD card to your computer.. not a perfect backup but ur pics and apps u donwnloaded would b on there lol... i see what ur sayin tho.. no winblows pc

Wow just found this in the readme from C-Skills that wrote the gingerbreak executable

Before using the softbreak, remove your SD card or any removable
media, or insert an empty one. Gingerbreak is going to exploit
the volume manager so if you have bad luck it might be that
it is erasing data while being executed.

Nice catch! I totally overlooked that. I'll update the Gingersnap & Rooting Guide immediately.
