Hello,
i have here from my friend iphone 7.
Original problem was selfpowering ON on charger and bootloop.
Mainboard was littlebit bended by nand. I have desolde nand, cleaned reballed etc and sodered back to mobo...cpu etc was covered with heatsink.
Now i have problem - after pwrON psu shows consumption approx 600ma and u1801 goes littlebit hot...PP_VDD_BOOST looks not shorted.
Always with connected cable is in DFU...i have tested to reflash with 3utools and i got error -2.
Unfortunately is not good idea to flash it with itunes because is needed to leave user data

can anyone help me what to do now please?

thx
