Hello all ! For those who use the "custom CID method" with a CID programmable SD card "Samsung" or "Chinese" :
Here is a Ktag 7.020 SD card image identical to that of post 1, but I re-encrypted it with a much easier CID. I did not generate this file with a manual solution, but with my own script. Thanks to svvag2000 for the original image !
1) You just need to change your SD card CID to : 123456789ABCDEF123456789ABCDEF00 (For Samsung evo SD card : With "evoplus_cid" or "mmc32" under Linux or Android, with super user privileges). (For China SD card : With the specific Chinese software).
2) Write this SD card image to your SD card with "ImageUSB" or "Win32 Disk Imager"
