Sorry to open up such an old threat, but i have simmular issues as mentiont above.
Ive gone to hell and back, getting my phone ( a MT6582 Lenovo A3600d ) rooted and TWRP on it, working and all. Yea im a prood noob.. !
But now im stuck. Ive put some compattible rom on my empty and formatted sdcard. Ive done all the flashing that is required to finally install the rom, but TWRP wont see the zip file.
Its in the root of my SD in the correct zip format etc. When i go to the TWRP file manager i also cant locate it. Eventho it tells me its reading of the sd card and not the internal memory. It will only display the maps and show some txt files. Dont know if thats normal. These are the only actuall items/lines i can see pop up.
Furthermore in "Mount" it wont let me check the box "Ext-SDcard", all the others i can check. Is this where the problem lies ? Ive removed the card and formatted it and put the rom zip file back on it a few times through my desktopcardreader.
Since ive allready flashed the phone its completly empty, only the TWRP recovery is accesable.
Am i missing something ? Any help would be greatly apprishiated
