Hi, today my galaxy s5 crashed and started to crash continuously at different points. Sometimes it arrived to the pin (but never allowed me to type it) and sometimes it was unable to boot even in the recovery. I tried to dirty flash and flash was completed at the 5 or 6 attempt. first time i got code 7 then 4. I tried to wipe all the partitions (data system cache dalvik.. everything) and i had to try like 6-7 times even to wipe. it was giving mount errors and error 4 and randomly rebooting. After wiping everything problem remains and i wanted to know if i can somehow delete partitions (maybe some are corrupted? ) or is my motherboard/memory completely dead?
