Hello people, I had the Galaxy S2 with custom rom 4.4.4, and I decided to install the CyanogenMod 13 Nightly, some of the worst mistakes I've made to install I made their respective wipes and factory reset as I said in the forum, but (Problem 1) I did not recognize the internal SD, it came out as damaged and it did not let me format [Img] https://img.xda-cdn.com/AK4aCCljwuUCpLqGKu-LUMP88m8=/https%3A%2F%2F3.bp.blogspot.com%2F-RUsLApyXvow%2FWbhvNqxtlCI%2FAAAAAAAABBg%2FWUi9FjkceAArWeF8E7vUR2AqorqHaZANwCLcBGAs%2Fs1600%2FIMG_20170912_181444.jpg [/img] So download another custom rom, enter the recovery which was the CyanogenMod recovery (different than the first) when you enter Apply update (problem2) I do not recognize the external SD card, that card gave Fat32 format from the pc, insert the card into 2 more phones without any problem but the custom does not give me access (problem 3) the following probe was to install another recovery but doing so by Odin I get: NAND Write Start !! and does not let me move forward I have installed Kies and drivers Samsung for mobile I do not know what to do, I've exhausted all my ideas. Do not panic the Android system Do not advance the Odin (if it detects the mobile) Do not install another ROM recovery CyanogenMod I wait and they help me and it takes 3 days thus

return it to your original ROM, then put the kitkat in your preference 4.4.2 or 4.4.4. then metele the cyanogen. I hope you do not have it in our language, but I think you will know. https://forum.xda-developers.com/galaxy-s2/development-derivatives/rom-cyanogenmod-13-t3223808
