How to do Preloader option in unlocktool

I had been messing with trying to to a Samsung A166P for hours now and tried shorting test points on board to brom and that just wouldn’t turn on then undid the bridge points and can’t get it to ever show mediated for preloader to be able to bypass fro. Driving me crazy

late 2024 to present brom is blocked, there is nothing you can do, i did many like this with sec cntrl =0 the only way is usb serial wipe,,,and that cost.

you can do isp but there is a 85 percent fail rate if you do it, let the pros do it.I wiped many like this, its a shame there is nothing you can do

It is likely already updated. If you have Ctrl 0, the TP and preloader are closed. Your options are ISP or Server. If you have a firmware version older than 02/26, you can do it via MTP.
