Based on my experience, and posted here in case it helps others ...
If you've installed pandaball's CyanogenMod based ROM or other CM7 RC2 based ROMs and are having wifi issues, it may because you forgot to clear the delvik cache.
I'm a bit of a noob to Android flashing, ROMS, etc, so it took me a while to realize that clearing the Delvik cache is NOT the same as just clearing the cache in the basic CWmod menue. To clear delvik, you have to select the "advanced" menu item in CW, then "clear delvik cache".
I was having issues getting my WIFI to work at all in CM7-based roms, until I followed the following steps:
Wipe/clear data
Clear delvik cache
Install rom from zip
reboot
After that, wifi works great on my p925 (LG thrill) with base p920v21E.
It's easy to blame a ROM for a newbie mistake like this, so here's hoping others will learn from my omission.
P.S. I'm still in "noob" mode on XDA, so I can't post in the DEV section as a reply..
Edit: Restoring wifi settings via Titanium Backup seems to re-trigger the wifi issues. I'd recommend starting most things (accounts, settings, etc.) from scratch when installing CM7 based roms for the first time.
I was completely wrong in my OP. The wifi issues remained, and what's more, I'm learning more and more about my mistakes and misconceptions with CM. See the results of my learning experience with CM if you're interested.

i wipe factory data and cache and dalv cache and still if i do this i get the same background i had like preveious versions of the rom....???
do wiping the phone really works??
to be more specific.... i used the cyanogen mod 6.0rc2 rom used a background with it i then wipe everything i can to try out a different rom works fine then went back to cyanogen mod night version or something it brings back the wallpaper i had use in older version roms i used???
I think thats a google backup/restore thing. If the image/wallpaper is available when the phone is reinstalled then it will restore the background.
Hello,
Apologies for the question in advance. I have read all related threads over the last couple of weeks, most notably the Classicnerd v0.04 Buttah in the Touchpad Development section, but as I'm new to the forum, I cannot post this question there.
I have finally decided to make the switch to Classicnerd buttah from xron 2.8 (which has been working beautifully).
My question relates to the install process. On the Classicnerd site, the procedure manual says that I need to ACMEuninstall first, however reading posts in the Classicnerd Buttah thread, senior members are saying there is no need to do this and I can just do the wipes and flash directly.
Can you please advise which method I should follow?
Also, does v0.04 include Gapps, which means I wont need to flash Gapps.
Thank you in advance.
The ideal instructions are to acmeunistall and then acmeinstall just CWm and Moboot...then flash ICS....
but you can just do following also..if you have problems then do acmeunistall
Download Classicnerd buttah version 0.0.4 and gapps v11 from classicnerd.net
boot into clockwork in ur tp
take nandroid back up to be on safer side
wipe data/factory reset
wipe cache partition
mount and storage..wipe system, cache, data
advance...wipe dalvik cache
flash classicnerd buttah
flash gapps
reboot
now dont restore any app or data from ur backup in Xron...install everything fresh from market to avoid any issues...
Thank you so much for your guidance, viny2cool. It's very much appreciated.
I'll try it tonight with ACMEuninstall.
Ok, so I went from Classicnerd to CM9 Alpha 2 to the CM9 Unofficial Nightlies and I am having an issue with the latest update. It seems that when I upgrade to either the CM9 Official Nightly or the most recent Unofficial Nightly, I am getting an SD Card Removed error. It seems to be linked to the upgrade from 4.0.3 to 4.0.4. All the apps that have been moved to my SD Card partition are not accessible. Anyone know why? I haven't wiped completely, because I am happy on 4.0.3, but I just wanted to see if there is an answer for this?

It sounds like something got corrupted. If you have a good backup, restore it, then wipe cache and wipe dalvik cache and install the latest nightly. That should do it. If you don't have a good backup, try wipe delete factory reset, wipe dalvik cache and install the latest nightly. You'll have to restore your data, but that's what you get for not having a nandroid.........
Good luck.
Edit : Rereading your post, I think you'll have to do a clean install of cm9. ClassicNerd uses different source. If you have a good backup, you can try advanced restore > restore data, or Titanium.
Yes, he's right.
When going from one release to the next in the same style of series (Alpha2 => Nightlies => more nightlies), you can get away with just a wipe of the /cache and the Dalvik cache. If you go from CN => Nightlies or Nightlies => CM, or any other combo that isn't the same series, you are best set to do a full backup, then a full wipe and start fresh. You can try an Advanced Restore, but be aware it might not work.
I too am having the same problem... it first occurred with the upgrade to 4.0.4. I wiped every thing restored cm9 backup and wen I'm instcalling apps and moving them to sdcard after about five apps my sdcard is removed and will not mount. So I reverted to cm7 (got to have headphone jack) and after moving some apps the samething occured again...

Since we are talking about wiping, I would just like to chime in and ask how that is done on the TouchPad. The only other Android device I have ever owned is my Droid X2 that I use now. And when I want to wipe that, Motorola has a method of doing it to where it sets you back to stock factory settings with a file they provide. Since the TouchPad isn't an official Android device and all, what do you use to wipe it and start over? A link to a thread that explains it would be helpful. I'm sure there is one. I will look.
for an answer to the OP i found this on rootzwiki....dunno if ok to post link but ima do it anyways...remove if frowned upon:
http://rootzwiki.com/topic/13277-cm7-fixes-for-sdcard-issues/
to fix my sdcard issues i AMCEUninstalled android and did a clean install of the latest moboot, gapps, clockworkmod, and cm9 A2. As for fixing the sdcard issue it also fixed alot of other things....no more Google maps constantly opening and wat not....much more stable.

Use ClockworkMod to wipe data/factory reset
Okay I have this problem in JB TW based ROMs I have tried (SweetROM, ULTIMATE, SuperBean) that whenever an app is gonna force close, the phone soft reboots without the popup "unfortunately, blah blah blah has stopped...". Is this a known issue or I'm the only one facing this? Thanks
try a later build of the ROM in which this particular problem may have been solved. These problems are quite common with the primitive versions of a ROM when it's in the development stages. Try sending PM to the ROM developer if you have such problems.
Like Varad said, make sure to also perform a clean install before you flash a ROM. This includes wiping system, preload, cache, dalvik cache, factory reset.
Always make a backup too.
hello,
i tried installing cyanogen 12.0 and then tried 11.0 and it installed and now on im on 10.2. The problem is on cyanogen 12..0, 11.0 and 10.2 my phone wont charge either with it on or off. Now my battery has gone flat
How can i fix this charging issue?
Also the buttons to left and right side of the home button doesn’t work either how can this be fix to?
please please any help ?
thank you
I did had a problem with charging the phone while turned off after installing cm11, reading the rom's thread I found that the solution for that is to set formats like this, during the install, it worked for me:
System => f2fs
Cache => f2fs
Data => ext4
About the other issues I recommend you to do all the wipes (system, cache, dalvik cache, internal storage) in order to do a clean install and also to do a extensive reading of the rom's thread and search for that issues. Remember to back up important data like efs with twrp before.
