How to take Motorola Photon 4g out of the grave?

Recently I ordered Motorola 4g from US.... It was with stock Sprint Sunfire OS. OS : Sunfire-2.3.5 Baseband : 4.5.1A (I am not sure about this whether its baseband or revision) Build : 1_SUN-254_4 **NOW ITS DEAD.... running in RSD Mode** So what I did, I was trying to install custom rom on that. Steps I had taken 1. Rooted phone via installing SuperUser and various rooting methods like ClickOnce, Photon -Torpedo but no one seems successful , while executing I got errors everytime. But after day or two I came to know about that my phone is rooted. As I was getting SuperUser popups on root operations. Then I installed CWM and tried to install the ROM from there but everytime I got stucked at Yellow Triangular icon (recovery mode). 2. Repeated step on rooting process and unlocking the bootloader by applying pudding.rar and fastboot commands and every time i got the error and Starting RSD Screens, but anyhow my phone recovers itself to its original boot state afetr pulling out battery and manually restrating. 3. Finally one day I use some other Recovery Tool , i am unable to recall the name. It installed and rebooted successfully in the recovery mode. I then wipe the dalvik cache, wipe factory reset and then tried to installl the custom rom that MIUI 2.68 i think . I was happy to see some designer screens on my phone and then it said rom installed successfully. 4. I then reboot my phone and found it in the Failed To Start2 , Starting RSD mode I tried various way to restore... 1. Installing pudding.rar using RSD lite but everytime I got sec_exception : sec_exception : b655, eddc,eb 2. I then tried reinstalling SBF : 1FF-sunfire-user-2.3.4-4.5.1A-1_SUN-198_7-CM-release-keys-signed-Sprint-US.sbf and sunfire-2.3.5-4.5.1A-1_SUN-254_4 but while enumerating phone I got error sec_exception febe 4e 4e I have also tried nopudding4u.sbf but the same result. Please,, help me and my phone out .. as its going to be more than a week... i feel handicaaped... Please guide me through the step by step , which file and when and please do provide the links of the files to download. **Update OTA with 2.3.5 before murdering.....**
