As always: I should have read more carefully before flashing my ZTE Open C with a Flame image and bricked it. After long sessions of re-flashing the phone, having issues with the image signatures and finally lacking files in the system partition, I managed to get back to at least a running FFOS_EU_EBAY_OPENCV1.0.0B04. BUT !!! The phone works, WiFi is ok, internet access and all the apps work, but the phone does not detect my SIM nor my SD-Card. The SD work during recovery mode, so it is not a hardware issue. I have access via Linux to the /modem partition situated in NAND-Partition sdb1 but have no clue about the contained files, which seem to be fine (though maybe no the right ones...?) Does anyone know of a "complete/full" system image restoring ALL of the NAND-Partitions or a file that could be flashed to restore the appropriate Modem-Files? I saw, that there are Modem.zip files on xda-developers for Android and FFOS, but they were of no help, since recovery mode does not accept them and I don't know how and where to put the files by other means... Thanks for your support in advance... !!!
