Finally the phone has been resurrected by using belam00r's help. Special thanks to stabbinbaz as well for offering his help.
It took over 6hrs to get this nonsensical device up and running.
The process remains simple, but sourcing and subscribing to all services is key.
Steps:
1. Flash bootloader from DC Unlocker to enter Fastboot
2. Flash board software in XML format using IDT (good luck finding that XML)
3. Phone should boot with no IMEI but access to ADB would be available
4. Use HCU to repair IMEI
5. Flash stock firmware through DC Unlocker in fastboot mode |
