Couple of questions for ClockWork Recovery Restore.

[randys52]

1. Boot into recovery

2. Backup your current Rom

3. After you do the Backup do you need to reboot and then go back into recovery, or can you just stay in recovery then do the restore.?

Are the steps for a recovery?

1. Wipe Data/Factory Reset

2. Wipe Cache Partition

3 Backup and Restore

4. Restore

5. Chose the Image to Restore

After you do the backup you dont need to reboot....just stay in recovery. Your steps are correct but after you wipe the cache partition, go to advanced>wipe dalvik cache.

Thanks Animal, I want to try out Old Frank. But I wanted make sure I could restore if I had to.

What is this dalvik cache or rather what does it do?

[animal67]

Quoted from Android Forums---------

"Dalvik cache is a program cache area for the program dalvik. Dalvik is a java based virtual machine that is the basis for running your programs (the ones that have the .apk extension). In order to make access times faster (because there's not JIT (just in time) compiler installed by default), the dalvik-cache is the result of dalvik doing an optimization of the running program. Sounds confusing. It's similar to the prefetch files in Windows."

Here's another explanation I found on Droid Forums. Kind of explains it better.....

"When Android starts up, the DalvikVM looks thru all of your applications (.apk files) and frameworks, and builds a tree of dependencies. It uses this dependency tree to optimize the bytecode for every application and stores it in the Dalvik cache. The applications are then run using the optimized bytecode. This is why when you install a new ROM, sometimes it takes a very long time to boot for the first time. Any time an application (or framework library) changes, it's reoptimized and the cache is updated."

The second does explain it better (even I can almost understand it).

So I need to wipe the Dalvik cache every time I flash a new rom and when I restore?

Thanks Animal - this is a great forum

No problem Randy. Yes....wipe all cache everytime you flash a new rom. Most of the developers will tell you in their write up if a full wipe is required. Some updates to roms dont require it but they will tell you if it does or not.

It is a great forum.
