[WARNING] Downgrading New Samsung are Dangerous

[eivelice]

hello,

i made this thread to warn you people to be very cautious when downgrading samsung phones now.

as i have bricked 2 new samsung models

1. c7010, frp only, i have flashed combi file same binary, binary 2 of the original firmware, but a little older date. it is okay but i can't remove the frp, so i decided to flash eng rom. date older than the original but same binary. it accepts the rom but it is stucked in odin mode with everything -2

after flash, it is stucked on NPMB fused : -2 and it will not flash anything. i can't flash on emmc tool because there is no support for it yet.

2. 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 read Samsung daily/weekly bulletins and there is no warning about your claims... I can't post them because they are confidential and I want to keep my source safe....

i work with them. i do daily works with samsung phones for the last 11 years and this is what MY EXPERIENCE is.

Dude stop fighting with me, Only downgrading issue is at Samsung bulletins, there is no issue about your claims like one week old firmware flashing and Bit becomes -2...

You are doing something wrong... I have Samsung GSPN access and several friends that work at Authorized Service Centers... Stop scaring people...

You are trying to keep thanks and making reputations so that people thank you...

i dong give a F about thanks, i give them something to think about.

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

Just cursing and bad words...you are lying...SAMSUNG authorized does not use jtag..

[amirsaishi]

today i downgraded two mobiles from 9.0 to 8.0 without any problem

i did not flash any combination, i just downgraded from 9.0 to 8.0 and and everything went fine

[...:::::NP™:::::...]

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.
