[Android Q&A, Help & Troubleshooting] justinr34gtr:
I'm very sorry if this isn't in the right spot. I've looked around a bit, and used the search engine, and I haven't been able to find anywhere that I think this belongs. Anyway, here's my problem.

Ok, so here's what happened. I was looking at my build.prop settings in rom toolbox. Out of curiosity, I changed lcd density from 240 to 160 just to see what it would look like. I planned on changing it right back immediately but Touchwiz kept force closing.

I then tried restoring my phone back to factory, but my recovery no longer works. I know how important it is to give as much detail as possible so here's the ENTIRE output from after rebooting into recovery, clearing user data, clearing cache, and then reinstall packages...

#MANUAL MODE#

--Applying Multi-CSC

Installing Multi-CSC

--Install from sdcard...

Finding update package...

Opening update package...

Verifying update package...

E:failed to verify whole-file signature

E:signature verification failed

Installation aborted

I had previously tried installing ClockworkMod Recovery ( through Rom Manager ) and thought it had failed because when I rebooted, it took me into the stock Samsung Recovery Utilities. Now I'm thinking that it may not have actually failed, and that I had to select 'reinstall packages' and that would have finished the ClockworkMod recovery install. I'm now thinking that the failure to verify whole-file signature is happening because I no longer have root due to clearing user data, and clearing cache. I may be wrong, idk.

I know how to reset the build.prop lcd density setting to fix that issue, but I have to wait for my aunt to get her computer back to root again. She's currently having it fixed, and I have no other access to a computer.

What I'm asking for help with is to either get my recovery utilities to be functional again in case I ever need to do a hard reset, or get ClockworkMod installed. Whatever is safer is the route I want to go.

I'm kind of thinking that ClockworkMod not fully installing itself is stopping the recovery from functioning like normal. The reason I think that is because I've restored my phone to factory stock many times. The sdcard was NOT in the phone those times and now it's trying to use 'update.zip' from the root of the sdcard when I select reinsall packages. Kind of like ClockworkMod recovery is partially installed, enough to try to use itself instead of the stock recovery, but not enough to be a working recovery.

As I said above, I'd really like to have a working recovery on this phone. I'm actually homeless at the moment, and I have absolutely no money to buy a new phone. Shiiit, I have to bum money from customers at a shopping center every single time I want to eat even. This phone is basically the only thing that keeps me sane. Being homeless is REALLY, REALLY boring as you can imagine. This phone makes it much more tolerable.

Sorry for the length of the post. If there's any other details that may aid in fixing this, let me know and I'll post them. I'm pretty sure I've provided all the detail possible though.

Ok, I typed that up while I was away from wifi, and decided to do a little more research before posting. I'm seeing that I was right about the ClockworkMod recovery not being fully installed. I didn't do the last step of rebooting and then reinstalling packages originally. Now. I'm wondering if the signature verification is failing because I no longer have root access or if it's something else. If that's it, I'm going to finish the installation once my aunt gets her computer back unless there's some way I can get it to reverse the partial ClockworkMod install.

Again, I'm sorry if this is in the wrong place, and for the length. Thanks in advance for any help you can provide.
