iPhone restore error code 2012
iPhone board is unfortunately one of the disturbingly more common ones being reworked in a chinese lab getting in EU as refurb, thus no clear history. Had a badly reworked faulty audio IC that was fixed, yet it showed little glitches partly due to aftermarket parts fit in the housing. After everything was finally put together with known good parts a restore was started with iOs 12.4.
Restore with iTunes got stuck first at verifying software, afterwords went into error 2012. 3Utools gets stuck at verifying filesystem, no error, it just hangs.
I can’t find any error 2012 reference, I fear a Nand issue but before wasting time on it would appreciate any insight if someone has already gone through something similar.
