Root What can I save?

[blksith0]

I'm stuck at the HTC white screen, and I can get into recovery and all that.

So basically, I had just installed this new ROM, and I just restored everything from Titanium and MyBackup and the homescreens were all nice, and it was a delicious looking AOSP Rom. I was just getting ready to apply some nice themes and all that jazz.

What I'm trying to say here, is that I know Im going to have to replace something with the recovery. But is it possible to replace just the boot and important system files, but keep my all my nice personal stuff?

I guess its the equivalence of reinstalling system32, but keeping my documents. Know what I mean?

Before you do anything, reboot the phone, let it sit at the white screen and see if it follows through. If not, pull the battery while it's at the white screen, replace and boot up. See if that helps. That has helped me in the same situation.

Ive tried doing the white screen/battery pulls to no avail. Perhaps I need to let it sit at the white screen longer, lets see if 8 hours will do it.
Going to bed now.

No unfortunately its still stuck there. Anything I can do?

When you restored everything with titanium backup did you restore apps only or apps and data? Basically what did you restore? You mention you were flashing to an AOSP ROM and restoring data could actually be part of the cause of your problems.

Although it is a bit of a pain, I would recommend either restoring a nand or wiping everything and starting over with the ROM flashing and restoring. If you use launcher pro you can save your screen setup and restore it from your SD card between ROMs, but even then you would need to restore widgets.

So bottom line, I would not try to restore only part of the ROM and keep your setup. Possibly Akaza could jump in and tell you how to do that, but my guess is it would end up being a bigger hassle than it is worth.

Edit: Another quick thought, have you tried going into recovery and wiping cache and dalvik cache and then rebooting? There is a chance that could solve your problem and it would not affect your current setup. I would try that first if you haven't already.

You could also just flash the Rom over itself without a wipe there by retaining data and cache and just replacing system and boot

 

[blksith0]

Well matt, its a little too late for that. Yeah, Ive tried erasing all the cache.
And with Titanium Backup, I restored apps+data. Gotta have my angry birds score. Why is that a problem?

Well a guy has to sleep...

You can have your angry birds data just not system data...

And even then there is a migrate system data option that apparently works though i have never tried it

A little clarification... app data is not saved in system it's in data/ data. Restoring app data isn't exactly what we are referring to when we tell you not to restore data. Though apps may fc if you restore their data sometimes, in that case just wipe the data for that app and it'll be ok usually. When we say don't restore data we mean system data which is often incompatible at least in part between roms especially aosp and sense. But apparently you can even migrate that...

Well, with the broken one (stuck on htc screen), I went into recovery and made a nandroid backup. However it gave me the option of what to choose, so I only chose data, and... I cant remember, I chose some things, but I didnt choose BOOT. I figured that boot was the broken part.

So with that, I wiped everything, then installed the MikFroyo rom again, booted, and then restored that nandroid backup.

I guess its like reinstalling windows, then still copying over your program files folder.
But thats a bad analogy because you wouldnt want to do that.

So it just finished restoring, and lets see what happens... rebooting...
It sure it taking a while on this HTC screen here... Wait, wait! Its done it! its booting! Oh yes. But we're not outta the ballpark yet, oh no.

Unfortunately, nothing is changed from the original MikFroyo ROM. I guess Ill just do another erase>install MikFroyo again>go through all my customizations and restoring... Darn.

Okay, here's the thing. You have to take into account exactly what you just did between the phone working and it not working. Always start with a cache/dalvik wipe. If that doesn't work, move on to considering what you just did. If you just flashed a kernel, for example, boot, and possibly system are messed up. If you just flashed a theme or most mods, you've most likely messed up system. If you just restored a bunch of apps via titanium backup, something /data is messed up. Those first two are the easiest to fix. Simply reflash the ROM, as matt pointed out. That will fix whatever broke in either boot or system. You'll lose all your mods you may have flashed after the fact, but those are easy to reflash. You won't lose any data that way. Alas, if you broke something by restoring everything with titanium backup, it can be very hard to fix. Broken things in /data, especially when system data are very tricky to fix. You should always make a nandroid backup before blindly restoring everything. If you're switching from AOSP to Sense or vice versa, restore as little as possible, restoring apps/data, only, but do not touch system data.

That being said, There are a few tricks here and there. If you made a nandroid backup at any point, or even from a previous one, you can extract the data.img and grab things out of it. Depending on your level of loss, that may or may not be a waste of time. It's probably easier to just take it as a lesson learned, and redo everything this time.

 

[blksith0]

Yeah I should have done a nandroid backup after each big step. Let his be a lesson to you all.
Oh well.
