This is meant to be on this SHOstock3 thread; but I will mention SHOstock2.

Yesterday I FINALLY upgraded from a Gingerbread rooted rom (Doomzday 1.5SE)

It had been working for me, and I need and rely on my phone for my job.

I finally had the free time and I've been having some hiccups and figured it was time. I read on this forum every day and came to the conclusion that SHOstock3 was for me.

So I followed the instructions and had issues along the way; had to revert to stock. Got past all that but I can't get to SHOstock3! I have 2 errors which I think are related. I spent the ENTIRE day yesterday searching and reading and tweaking. So it's not for lack of trying. I can get SHOstock2 with no problem even though the error is still there; but it doesn't seem to affect SHOstock2 or prevent me from loading and running it.

I have the "E:signature verification failed" error. Which despite me trying everything I can think of; is still there! I searched our forum, and tried solutions as well as tons of other google phone/tablet forums. It is a common problem with every type of Android device. The thing is; it seems others' have had success fixing it different ways. In-other-words; there doesn't seem to be a (one size fits all) solution. I do completely wipe between rom changes. I did try both Enabling and Disabling signature verification in CWM. I tried different versions of CWM. I tried different kernels.

I'm also having this error within CWM:

E:Can't open /cache/recovery/log

E:Can't open /cache/recovery/log

E:Can't open /cache/recovery/last_log

E:Can't open /cache/recovery/last_log

This error is very common among Android users as well and very few people seem to have success fixing it. (Some think it is an error with their internal SD card going out.)

I can't help but think the problems are related. I have the above error in Shostock2, but SHOstock2 runs smoothly in spite of. But this error prevents me from installing SHOstock3.

Yes, I tried a couple of times reverting to stock then reinstalling only to have the error return.

I do have a theory, but I would like feedback before attempting to fix it.

On both SD cards (internal and external) there are folders:

E:Clockwordmod/backup/(then any one of various folders in which the name of the folder is a date)/cache.ext4 (which is a zipped folder)

My theory is this is the culprit. I notice on both the E: and F: drive the dated folders are different. I'm wondering if there is either a consistency problem or if one of more of these folders are corrupt? (I do and did try with and without the external card.) I'm wondering if deleting one or all of the date folders could solve the problem? I don't delete things unless I'm sure.

Also to mention: yes I checked the md5 checksum on the SHOstock3 downloads and even downloaded them several times and tried installing from both internal and external cards.

Right now I have CWM-based Recovery v6.0.1.2-Siyah

I'm in the process of learning how to use ADB. (I'm just pressed for time)

On the upshot SHOstock2 is amazing; and if I have to live with it. NO PROBLEM! It's great! Thank You SHOstock!

Any idears on what I might try? Thank You in advance!
