Ok, here we go...
So I've had my optimus v since march, rooted it with superoneclick and uninstalled the crapware from it. And go figure, hardware failure hit! VM sent me a refurb unit, and asked for the old one back. Before I send it back I need it unrooted, which is no problemo, as superoneclick can unroot too. The problem is: busybox is still installed even after unrooting, and the installer can't remove it. I tried removing it in DroidExplorer(PC) but the permissions on the busybox file in xbin wont allow removal, and I can't seem to change them even with chmod in adb. Am I missing something? Am I better off trying to flash a stock rom to the old device? And can I do so while leaving no evidence like a custom recovery? And on the topic of flashing new roms, can someone give Me a list of the only ways to brick my phone? For purposes of not bricking, of course. I've read the stickys in the forum, watched countless videos, and a find a lot of contradicting information on a lot of things, can someone set me straight on a sure fire way to return this defective phone to factory, and/or flashing roms?
Also, what's YOUR favorite rom for the V?
Thanks for your time!

Well you can revert back to stock with this:
And my favorite all around every day use rom due to battery and performance and features is:
Only thing I didnt like about the rom is the launcher, so I downloaded launcher pro from the market which is fantastic once you customize it how you want. good luck.

Connect to your phone via adb
Open SuperOneClick.exe and choose temp shell root (may take a couple of tries)
Once you are temp rooted, type adb shell (you should see a # sign, if not try temp shell root till you do)
Once you see the # sign in adb shell, type exit
Type adb remount system
Type adb shell
Make sure you still have the # sign, then type rm /system/xbin/busybox
Type adb reboot
I believe that will remove busybox without rerooting you permanently.
My god.... that easy? I've been mucking about in adb and google for a week now. Once I get home ill give it a shot. Thank you so much!!! That guide needs to be the first thing stickied (no offense to this helpful abdoul fellow). Ill try that rom you pointed out, my battery life blows with the stock rom.
Are you able to tell me the "no no's" when it comes to flashing? Is there any way to permabrick droids by slipping up?
Thank you again

hmmm, try this:
In adb shell, with the # sign, type
chmod 777 /system/xbin/busybox
then try the rm /system/xbin/busybox again. You may have to find a way to chown the file.
Although the command window remount has always worked for me, you may need to remount system in the adb shell with this line:
mount -o remount,rw -t yaffs2 /system /system
If any of this works for you, I will update the above posted instructions.
If my advice fails you, asadullah will probably know the answer. His videos may confuse some, but his work is impecable!
I appreciate your help and time very much!

flashing the rom doesnt erase any activcation info that may be stored in the phone.
However, if you are flashing a rom that does NOT have the 3G data dropping fix, then you wont see any improvement.
Bumblebee and aospCM7 have that 3G data dropping problem fixed, even on aosp, youll see MUCH better battery life than you do currently.

It will put your phone into airplane mode for 12 seconds every time you boot your phone to remove the bug. Let me know how that goes.
Heres the App:
[APP] 50% time without a signal fix - 2/2/2011 - xda-developers
Edit: I did have the 50% bug!
Im using the Reborn rom linked in the first response in the thread. I wasnt aware of there being a 3g dropping bug, and have actually received my new phone because of it! This rom has only dropped data connection once since flashing the new rom. I can only assume this means either its using something else for data now, or it has a fix for the problem. Can this device use another type of connection for data? Thanks for your help and time!

Ok, so I've been tinkering all day/night on this issue, with few good results. Ive tried doing a complete wipe of absolutely everything, and Reborn simply won't allow my 3G to work. I tried Bumblebee, it seemed to work fairly well, but it was missing a lot of features i like about Reborn. So I got Cyanogen 7 to run long enough to configure everything, reboot a couple times, and run Linpack. Linpack reported under 2 mflop every time I ran it, so I tried a reboot in case things were cluttered. That reboot resulted in it not starting back up, it would only sit at the (oh so shiny) splash screen, even after several attempts. I suppose Bumblebee is the most functional rom I have found so far, but it lacks the shiny bits! So now I'm back to my Reborn nand backup, and am at a loss of what to do! accept lack of 3g, and enjoy reborn? enjoy 3g and lack other functions? or have an OS that does everything but go fast and reboot?(ha, like that's an option). The way I installed cyanogen is right here, I'm not sure if I just got an old version of the rom, or if it is truly incompatible. can you, or someone please take a look at the rom linked in the tutorial I followed, and tell me if I'm just using a bad version?
This image is a SS of reborn running as I type this reply; can you verify by the status bar that I indeed am not using 3g, and am not hallucinating or mistaken?
-Chris (it really is breaking afterall )
also, I just noticed my droid is not entering usb debugging mode, but still connects to adb and droid explorer as if it were.

It isn't EU. Look at it closely and you'll see it is EV. As in EVDO, which is 3g. It is just part of the customizations he made to differentiate from other roms. If the link you posted is the CM7 rom you installed then you do a very old rom. Zefie's CM7 is an old rom that has not been updeted in months and is considered dead. If you must have a gingerbread rom the look into the aospCMod rom it is newer, and they are still working on it. I believe the current build for Optimus V is 6/01/2011. He does have a couple of different builds for different phones, so make sure the one you get is the VM version. It should have VM some where in the name .zip file.
Thanks for your reply!
Well, time to hunt for a newer cyanogen build to play with!

I am kinda shocked with Reborn atm. I used it back when it was Nameless and it was nice but the battery drained alittle fast and didnt have the power widget in notification bar. This time around I just installed the TWS 50% fix .apk and my battery life is amazing and with all the improvements its now my choice ROM for 2.2. Hopefully the next update has a fix for the TWS bug.
