[Q] How do I unroot my samsung galaxy SII epic 4g touch?! (2012) - General Questions and Answers

I rooted my phone following zedomax's instructions. Once I had installed a rom I had no phone service so I got tired of trying to fix the problem and rerooted the phone back to stock. Now i lose service every now and then and am forced to reboot my phone. I want to flash back to a stock unrooted version ASAP. i have been looking for dayyyyyssss and all i find are broken links or directions that do not apply to me. Please, for the love of all that is holy, someone help. (((

[Q] need help please. can't grt phone to activare still

I got my one SV k2_cl from boost a little over a month ago and got the bootloader unlocked and rooted, working fine until one morning it wouldn'tmake calls or texts. I tried to factory reset and when I tried to boot got stuck at the HTC logo. Took me 2 weeks to get it to even flash a Rom on here that will somewhat work. I've got WiFi and partial 3g 4g connectivity but no voice at all. When I try to use the phones its activation tool-error, tried manually programming phone- nothing. I'm stumped. Can someone please help me out here. Don't want to have to buy another phone if I can help it. The only guess I've got at the moment is that if I could get a stock original rom to flash I'd be good to go probably and just hold out on doing anything else to it until after the kitkat ota is launched. The few stock roms I've tried either wouldn't download for some reason or just won't flash right. Thanks in advance for any help guys. I've always been more of a hardware geek more so than software but I can usually muddle through following guides of course.
I'm not much into boost, but did you try to flash the available RUU?
help...
As a matter of fact I have tried that and unfortunetly the installer locked up on a reboot of the phone because the phone wants to do the "Android is upgrading # of #" on every boot. That was why I was thinking since adb/fastboot and the HTC One Toolkit all sorta work that if I could get ahold of a working stock rom to flash on there and I have a stock CWM backup still on my laptop from when I first got the phone rooted and everything working. But of course thanks for the tip anyway. I wish that would work. It seems to be the easiest way to install back to stock.

[Q] Samsung Galaxy S3 Trouble (Straighttalk Running off verizon)

Hello, it's my first time to xda developers. I followed a guide to get cwm on my straighttalk galaxy S3 running off of verizon. It told me to use a dsvzw image. i did, but then it showed me updates in cm updater, and i didnt look closely at the name of the update package, it said cm11 d2lte. well now the phone is saying no sim card and isnt showing that it is picking up service. i have tried to install cm 10.2 back through my recoverery but its still the same. i am running clock work mod recovery, the latest. I have no idea what do to fix this. its my only phone so any help would be greatly appreciated. If i can get my stock rom back thatd be great, might actually help the device. anyway, thanks again
