[Vibrant Q&A, Help & Troubleshooting] cahuja:
Here's an experience with rooting, lag fixes and voodoo (final item), in case this is useful for the various developers or others trying to use what the devs are producing....

Thank you to all the devs for so many choices - and some of the software needs error handling improvements :)

Okay, to start with while rooting device with Super1Click, there was an error (partition full) while "busybox" was being installed. SU worked, so i kept looking for stuff to fix the busybox install which was broken ("Seg faults" when trying any of the commands). "Busybox installer" from Market can install but no option to un-install. Ti Backup will go ahead and use its own included busybox...etc. Un-rooting via Super1Click did not even seem to remove the rooted-ness, let alone cleanup the broken busybox.

So now phone is running with a full /system partition and everyonce in a while it just freezes and only "hard" resetting (pullng out battery) can get it going again.

So I decided to delve further and maybe improve performance as I had read about on XDA (while poking around for the gTablet options). Decided to use TiBackup and save stuff first in case i mess up everything ( like i messed up avatar movie when i copied it off and back to SD card..). Of course, no busybox but thank yu Titanium for having the "problems" button and installing what you need elsewhere and working like software should. Okay now i have backups of everything done.

So now its rooted and backed up, so i try OCLF to get performance and of course ext2 tools & fix is not enabled because /system partition is full.

Back to cleaning up the "bloatware" (why cant the OEM/carrier make the partition bigger if they are going to add bloatware ?).

So after deleting a few things, now OCLF installs but fails towards the end - trying to 'mv ...playlogos1 to ...playlogosnow' (partition is read-only error) and does not 'catch' and undo itself like it generally does on other errors it runs into. Okay so now stuck with a partially completed OCLF and the menu system will not recognize the presence of fix and thus cant use the "undo" menu item.

But, thank you for another menu item which "restores" the old playogos file and suddenly lag fix can be undone...great, more reading on XDA, discover that Voodoo is the way to go, not unsupported OCLF.

btw - found the feature of sending off the logs on error pretty handy, i'm sure its not such a nice feature from your end unless you have an email filter setup for it.

Now to the topic of this post - OCLF undone, deleted OCLF ext2 partition file, fixed busybox by using busybox installer (no uninstall option available), read all the XDA threads...(nary a thread on /system partition full - doesn't anyone else run into this problem with all the stuff they do ?)

Downloaded SGS Kernel flasher, got Voodoo for Froyo KA6. Decided to go ahead and put clockwork mod and do a backup just in case...also saved kernel via SGS

Flashed Voodoo, great robot voice technique till it said "No space on parition" and 'abort' or something similar and finished booting (then i'd rather see a log brought up after the reboot is finished).

Downloaded "Voodoo Controls" from market and nice it can see that 3 partitions are converted, but /system is not BUT it says Voodoo sound is not supported by the kernel (so assume that was the stage to be done after the "abort" happened on system partition.

Deleted more system "wares" reluctantly, uncheck boxes in Voodoo control and reboot to remove ext4 conversion. check boxes and reboot and voila - now all 4 partitions are converted, but still sez no Voodoo sound supported kernel. ?? oops no sound fix stage executed if already installed...

Current Status:

Quadrant scores at 1436, not different than when only 3 partitions had been converted (941 on stock). Btw - Linpack scores haven't changed since it was stock (12.78~13.48).

Now sometimes it shows the cpu is running at 100Mhz or 400Mhz....used to always say 800Mhz when it was stock.

Voodoo Sound still not available in controls. /system is back to 1.6M free from 8.4M at height of removing bloatwares.

Next strategy:

Uncheck and convert back to RFS, then flash back saved original kernel using SGS (thank you for very nice program).

See about /system again - dont have anything left to remove though..wonder what has eaten up the space (clockwork mod ??)

Flash Voodoo kernel again and hopefully wll go through and get Voodoo sounds fixes this time OR just do Overstock+Voodoo ROM...

Anyone have suggestions / comments on the strategy i should pursue next ?

Main goal is to get a phone that wont freeze at random moments and secondary goal is to make it fast as the hardware allows it to go but staying close to stock software so the next update from T-mobile requires least (=no) effort.

Another ques - anyway that i can 'insitu' increase the /system partition size so i can put the bloatware back on and not have a partition that keeps going full when i fool around trying out different things...can it even be done in-situ that is?
