After a radio recovery (fastboot flash modem+modem1 NON-HLOS.bin), I found I lost the radio/wifi/bluetooth. Also the IMEI/MEID/SN are gone too. After digging a lot on the internet, it looks like my EFS partitions may be hosed. I'm asking for help with those have MI2S-CDMA, can you create backup for EFS partitions so that I can recover? It's almost impossible for me to go to China to get it repaired in the foreseeable future. The partitions are: shell@android:/dev/block/platform/msm_sdcc.1/by-name # ls -l m9* lrwxrwxrwx root root 2014-05-09 11:30 m9kefs1 -> /dev/block/mmcblk0p12 lrwxrwxrwx root root 2014-05-09 11:30 m9kefs2 -> /dev/block/mmcblk0p13 lrwxrwxrwx root root 2014-05-09 11:30 m9kefs3 -> /dev/block/mmcblk0p16 lrwxrwxrwx root root 2014-05-09 11:30 m9kefsc -> /dev/block/mmcblk0p14 The steps to create a backup: adb shell su dd if=/dev/block/mmcblk0p12 of=/sdcard/m9kefs1.img dd if=/dev/block/mmcblk0p13 of=/sdcard/m9kefs2.img dd if=/dev/block/mmcblk0p16 of=/sdcard/m9kefs3.img exit exit adb pull sdcard/m9kefs1.img adb pull sdcard/m9kefs2.img adb pull sdcard/m9kefs3.img Please be aware that MEID/IMEI/SN are in the paritions, please don't send out if you are uncomfortable with that. If you can locate your MEID/IMEI/SN in the image, can you clear it and tell me the offset, and endian/format? Thanks a lot.
