T380 tablet frp only, i success on flashing combi file, i enabled usb debugging, then when i am flashing it back to original firmware, 1 letter older than the original, same binary, it became NPMB fuse: -2 also. this 2 phones are good and perfectly working before. i am very good at software, more than 10 years of experience and this is a new for me to happen. i have boxes for samsungs, i even have jtag and emmc tools. but i can't fix this 2 because of new security samsung puts. so now, i am very cautious when flashing this phones, it will be a big problem for all of us. hope this helps you people. |

i also have a lot of friends in samsung service center and the only thing that can fix this problem is JTAG. the question is WHY it did. and i gave the hints on WHY. if you don't have the slightest idea on why, shut up. i did not do any wrong as i am confident in my software knowledge. i spent more time in software than hardware. i flash 10 to 20 phones a day not just samsung and repair frp with different kinds of softwares and such problems. i know what i am doing. NOT JUST READING samsung will not and never will put anything in reading that will give technicians a heads up. it will make them legally responsible if they post such. i study first then apply what i see is correct. i am not a layman that does things without thinking. that is why i warn people. so that they will not suffer problems. no regards | |

Member: 1162626 Status: Offline Sonork: 100.1591727 QQ:2337938173 Thanks Meter: 11,110 | For downgrade purposes only needs the same binary firmware, I do not see any risk, I have done many more new models every day. So this topic only waste forum space. Suppose:- I have downgraded right now the Samsung SM-A750F / DS Android 9.0 to Android 8.0. ⬇️ ✅ Thread Closed.
