it started by saying os not installed but then I have access to "recovery mode" where I tried to wipe data and did factory reset but it displayed "ios not installed"...
so I found some solutions online and I tried some but during the process the of formatting the following::-
> fastboot erase boot
> fastboot erase cache
> fastboot erase recovery
> fastboot erase system
> fastboot erase userdata
> fastboot flash bootloader bootloader-grouper-4.23.img
> fastboot reboot-bootloader
> fastboot -w update image-nakasi-jwr66y.zip

* it could not locate the fastboot flash bootloader bootloader-grouper and failed
*the fastboot reboot-boatloader also failed..

so skip them and proceeds to the last step and that was successful..
so when I tried to restart it, it displayed "booting failed" and I can't have access to recovery mode anymore.

but guy, why would you erase all those partitions without flashing anything back to them? including bootloader?
can the phone boot into any other mode except recovery, like fastboot or bootloader?

did you place the bootloader-grouper-4.23.img file in the same folder as the fastboot.exe file?

1. can you get access to the original firmware?
2. crosscheck the format,position and name of the bootloader.img file you're trying to flash. the problem must lie with one
