recently I tried to fix my wifi antenna and ended up disturbing something that made my touch unresponsive. Okay just to make sure that my Display unit was not damaged I plugged in another display set and still the touch was not working!
what could have possibly gone wrong?
What can I say but BRILLIANT!!!!
You have saved me a bomb - very easy and much appreciated!
I had 2 broken iPhones and thanks to this guide I have a working one and a load of pieces :-)
Thank you very much for these instructions, which are aircraft maintenance quality. I had 2 phone: one with broken front glass and bad battery but with 32G. Other one good conditions but only 16G, which left over after getting 5s. So I changed logic board assembly from 32G to other frame and left all the rest inside. Voila, there it is fixed 32G 4s phone ready to use after recharging battery.
Instructions are so good that it takes me about 1 1/2 hour to disassembly and reassembly 2 phones and I had´t done that ever before. I just read instructions first and then followed step by step and checked out comments.
