I currently have a Samsung Galaxy S4 SCH-I545 NC5 4.4.2 Kitkat on Verizon Wireless, the device is rooted and running a custom kernel with Ktweaker. I attempted to install a new rom (Cyanginemod 10.2 stable) using Safestrap custom recovery. The phone didn't take the rom so no biggy however the backup wouldn't restore. Now the device won't even enter any form of recovery or download mode only display the Samsung logo. I have already tried flashing the stock firmware and pit md5 file on the device using the latest version of Odin. No success only corrupted data and a lost system backup.
