I personally think the Repairability score should be higher (based on how far I got with the repair). I am by no means a professional phone fixer, but I have experience. I was able to disassemble two essential phones without damage to the screens, and swap the motherboards, as well as all parts ended up still working (I tested every part). I heated the phone, and was careful with my fingernail to get the adhesive off after lifting with the suction cup. It took awhile but if you’re careful, you will be fine. Other than the screen, the rest was a breeze to replace the motherboard. I’d rate it about a 5/10, as it is still hard, but by no means should someone avoid repairing their phone because of the low score given.
