Does the webOS doctor undo 100% of all changes

I would like to have an answer to your questions also for the same reasons. Have you had any luck

In my own testing with using kernels available via Preware, when using WebOS doctor you will essentially reinstall the factory kernel and you will loose any custom kernels and/or patches that you have installed independently. WebOS doctor does not address issues with volume corruption in my opinion.

I used dd to backup some of the lv's in the store vg but have not actually tried restoring this to make sure I can get the device working without any major headaches.

What about your app settings, the apps themselves, and the files you have stored on the flash? Does WebOS Doctor wipe those?

I asked a friend this who's been doing WebOS developing for quite sometime now, & he said: "yeah, it basically reformats it but keeps the usb stuff"
