Missing stock CertInstaller.apk preventing me from upgrading

[cmtptr]

Hi,

I am unable to perform an OTA upgrade on my Motorola Droid due to an assert during the upgrade process:

Finding update package...
Opening update package...
Verifying update package...
Installing update...
Verifying current system...
assert failed: apply_patch_check("/system/app/CertInstaller.apk", "429cf7545b4f36d58ddc874ca805c35e9b098044", "47337b764a1ef7323d0e41ecdc70aa2ec1010011")
E:Error in /cache/bede60e851bb.signed-voles-FRG83D-from-FRG22D.bede60e8.zip (Status 7)
Installation aborted.

Upon further investigation, I noticed that /system/app/CertInstaller isn't even there. There is a CertInstaller.apk.patch and CertInstaller.odex.

This has been preventing me from upgrading for a while now, and the recurring message on my phone prompting me to upgrade is getting pretty annoying. What are my options at this point? Can I somehow recover the stock CertInstaller.apk from somewhere? I don't know how this file was removed, or even whether it was ever there in the first place. Is it safe to simply remove CertInstaller.apk.patch (which appears to be an empty file, anyway)?

I will greatly appreciate any suggestions!

How is it that nobody seems to have an answer to this? There is no way that I'm the first one to have this problem... I have not even rooted the phone or done anything else "unsupported" with it. What gives?

Thanks in advance for any responses.

Could someone at least be kind enough to redirect me to another community where this question might get answered?

Thank you.

Are you doing a manual update (i.e. not OTA rollout) I'm assuming you are. If so, did you rename the update "update.zip"? I've heard that gives an error code like the one you're seeing.

OP: since you haven't done anything "unsupported", have you taken it back to a VZW store? You shouldn't need to install any additional files for an OTA update, and even update.zips are pretty much self contained.

Another thought. OP: have you checked out xdadevelopers.com? It's the forum where a lot of ROM developers hang out. You might want to try your luck there.

Sorry for the late response; I thought I had this forum marked to email me when someone responds.

lennyjew,
this is not a manual update. It is OTA.

RyanB,
I was hoping to resolve this without going to a Verizon store, because in my experience "customer support" is usually clueless. I'm afraid their solution will be to hand me a new phone, or something equally stupid.

And I hadn't found xda-developers.com. Thanks for the tip, I'll try it out.

OP, you're concern over store support is certainly valid. Other than a factory reset (wiping ALL your data, I'm not sure you have much choice). Do keep us posted on how you make out.

Unfortunately I ended up going to a verizon store and this is what they did. But oh well, at least the problem is solved. Still, it would have been nice to know what happened to get me in that state.

Thanks to both of you for your help!
