Yes, it worked perfectly! The repaired broken line was apparently power to the LED backlight.
Hella clean, nice going

if it looks stupid but it works, it aint stupid. im stealing that method.
great precision work there too.
Thank you kindly 👍
The customer was damn lucky I was able to fix that, as he had only come in for a replacement battery. Once I opened it up, I found a lot of corrosion over that entire half of the cable, which I had no choice but to disconnect to remove the board first.
Welp, that instantly broke whatever marginal connections it did have, but it came in working otherwise, and I didn't want to have to try explaining how servicing his phone caused more problems, so I did my absolute best to clean it up, with vinegar and then rubbing alcohol on Qtips.
By the time I got it as clean as possible, everything worked, except the backlight. That's when I had to look extremely close to spot that one broken trace on the ribbon cable.
I hate to say it took me damn near an hour to get everything lined up, temporarily taped in place, and finally actually get the solder to cooperate, flow right and not bridge any contacts.
I don't even think we ever told the customer about the water damage he came in with, but the boss was impressed and the customer was happy.
That is honestly an incredible job.
