[Q] Full wipe before flashing backups?

Do I need to format / wipe anything in the CWM screen before restoring a flashed backup?

This is my personal procedure evertime I install a new rom, or revert to a saved backup. I am a noob, so I don't know if it's necessary, but I do it by habit now, and it seems to work for me.
1.wipe dalvik (in advanced menu)
2.wipe cache
3.wipe data/factory reset x 2
4.wipe system (in mounts and storage menu) x 2
5.(optional) wipe dalvik,wipe cache
6. Install zip or backup depending on what my intention is
7. fix permissions
reboot
edit: Actually, this isn't "MY PERSONAL" procedure...this is what was recommended to me from other valued members of this forum. I have simply adopted it into my routine.

That's a whole lotta wiping... wont hurt anything but very redundant.

I thought dalvik couldn't be wiped in Recovery- it gets an error message.

I have external recovery... I haven't updated CM maybe it will take care of it... could it be an SD card issue? I mean I haven't seemed to have had any issues... dunno...

It depends on what the backup is. If the backup is just an older version of the same rom I will just flash right over sometimes. If you are trying to restore a gb rom over a froyo, you will have to wipe first. Any time you are in doubt, just wipe.

I get the same path error to sd-ext. I've wondered what sd-ext even is, there is nothing in it and it is not my external or internal memory because they are in different directories.

[Q] Dalvik Cache Issue

Hello,
Whenever I try to flash on a new ROM I always wipe system/data. Then fix permissions. But whenever I try to wipe dalvik cache I get the same error (well.. at least I think it's an issue) every time,
E:Can't mount /dev/block/mmcb1k1k1p2
(File exists)
Davlik Cache wiped.
It did say that it wiped it, but it didn't mount.. any suggestions? Does it get wiped?
Thanks
Edit: Also should add that I had that this problem before and after odining to stock.. didn't think of that before.

[Q] rom install via cwm

Please excuse me as I am new to this....
I have a g2x rooted, nvflashed cwm and installed EaglesBlood build 5. Each time I have installed it after booting the phone into cwm and .... please see remaining post......
clean install of egb
1) Power down phone and restart / boot into clockworkMod Recovery v5.0.2.0
2) Select " -wipe data/factory reset -- Wiping data...
Formatting /data...
Formatting /cache...
Formatting /sd-ext...
Formatting /sdcard/.android_secure...
Data wipe complete.
3) Select wipe cache partition -- Wiping cache...
Formatting /cache
Cache wipe complete.
4) Select -advanced
5) Select -Wipe Dalvik Cache E:unknown volume for path [/sd-ext]
Dalvik Cache wiped.
6) Select +++++Go Back+++++
7) Select -install zip from sdcard
8) Select -choose zip from sdcard
9) select -p999_6_26_12.zip
10) Select -Yes - Install p999-6-26-12.zip
Then follow the remainder of the configuration options of the install ( specifying 21y ) as an option and gaps from sd card and then run the installer. Install completes stating " Congratulations...
EaglesBlood has been installed into your devic
Installer Status:0
Can someone please tell me why I have an error " E:unknown volume for path [/sd-ext]" being displayed after selecting _wipe Dalvik cache. The phone then completes wiping Dalvik cache.'
As stated earlier, the program does install and apprears to run as well as egb build 4
Is there something I need to do to get this issue resolved. I have tried a different sd card as well as then formatting it with cwm and or in my computer (scanned it using win7) for errors and bad clusters, and copied files from my computer to the root on the sd card. I did root, flash CWM using nvflash, do a droid bachup prior to first installing EGB build 4. and now am at a loss as to how to remedy or repair this "unknown volume" issue on a new install.
Any and all help is GREATLY appreciated!!!
Thanks in advance.

I received that error before while wiping davlik. But only once after I reboot an tried again I never got it again. Am sure you tried that just giving my experience on it

Its normal for are device we don't have sd ext.... That's why it skips over and continues

So it is not dependent on baseband, kernel, rom, etc. It is just a g2x thing, and nothing to be concerned with while moding/flashing various rom's ? :good:

CWM Recovery ?

If you select mount/unmount.
What are those options used for?
Mount system. Sometimes that says mount sometimes unmount?
And when flashing ROMs do I need to go under and select format system? Sometimes, after flashing a ROM from clean, I still maintain system apps such as camera.

When CWM gives the option to unmount system that means its already mounted and vise versa. You do not need to format system when doing a clean flash, you just need to wipe data and wipe cache, and optionally wipe dalvik cache.

Actually a true clean flash does include system
Sent from my LG spectrum (that's right) blazing fast on cm10!

For a full clean flash it is recommended to wipe /cache /data and /system
In regards to OP, when a directory is mounted it is readable. You may need to access files in those folders so they are mountable. Unmount to wipe.

fail to factory restore

Pardon me but i cannot find the right place where to post my problem.
After failing horribly to instal zombie over crombi and failing also to restore a nandroid, I tried to do a factory format but now it says unable to mount /cache twfunc::copy logcant open dest log file /cachemkfs.f2fs binary not found, using rm -rf to wipe
wiping data without wiping /data/media... Done.updating part details...
E"unable to mount ,' /cache
I really feel at a loss as when it happened the last time on the other tablet it came round fine after a full format, but this one doesn't want to know..
Please help thanks

Hey mate ....
Sounds like you got yourself into a pickle .......
Give this a try .... Boot into recovery and ........
Code:
adb shell
killall -19 recovery
make_ext4fs /dev/block/mmcblk0p8
This should format /data, You will need to use the hardware button to force reboot......
reboot back into recovery and see if /data can be mounted now ......
Thx Josh

Thanks for the quick reply do you think this will fix cache mount and dalvik mount problems as the system can wipe date but not dalvik and cache.

Fixed

After much formats it appears to be that twrp was corrupt as after using a fresh recovery blob every thing seems to be in place and cache and dalviki can be mounted.
The only quirk is that no matter how I try to instal Zombie after the message to restart and enjoy it just hangs on the droid animation for more than an hour, so for the time being I went back to crombi-kk until someone knocks some ideas into me.
Thanks
