Still problematic for the gnex. TWERP world great.
Fixed it for you Steven.
My experience tonight has been different using CWM (ClockworkMod Recovery) and RM (Rom Manager). Though my situation may be different and a YMMV situation. I took all my MBP files and transferred them from my A855 to my I515. And ScaryAlien's app has been a gr8 help as well.
And just as a note, I'm only using the stock 4.0.4 'rom' rooted. I have yet to flash a custom rom.
I had already flashed the CWM touch 5.8.x.x and made a few backups with that. Then I restored via MBP (MyBackupPro) my RM and license. RM wanted me to flash the latest CWR (albeit non touch). So I did and then used Scary's to flash the CWM touch 6.0.1.0, irregardless of what RM reported to me because it wanted me to pay more $$ to do so. Rebooting into recovery from RM (Rom Manager) was a success into CWM touch 6.0.1.0 and also showed all my backups created with CWM so far.
And then I decided I would try to do a 'dirty' flash of CM 9 and the gapps for the i515. Using RM, I selected "install ROM from sdcard'; and selected the cm9, gapps and such, selected the 'dirty' options, just wipe dalvik and cache, but not do a full wipe.
Well, it sat there and wouldn't quite (after five minutes or so) get past the CM9 bootanimation. So I pulled the battery for about 60, put it back in, booted straight to recovery, restored (via CWM 6.0.1.0 touch) my latest backup, and now my phone is back where it was.
Moral of the story?
Koush was the first one to get 'root' on an Android phone. Google it. He is the developer of CWM and RM. Sometimes there might be a few hiccups, but it is his stuff that will always work.
Everyone else is potentially a twerp.
Just saying . . . . .
From my experience, I have no problems at all with CWM 6.0.1.0 on the I515, maybe Steven . . . . . . . . . . . .
