For me it is safer to drill than to lift the nand. Not everyone has a good soldering station, the nand can break due to heat, break when handling it, break a pad, a lot of dirt spread by the flux, and thermal stress in general. It is very likely that the board will end up broken due to not knowing how to recover a pad or the chip itself. A jumper under the chip by joining dots, you connect the battery and goodbye. It is a job that is not paid, the client does not care if you install an adapter or a fixed point, if the adapter comes loose, the problem lies with the installer. Drilling is cheaper, cleaner, safer and you get the same result. A fixed point.
