Can I solder the wiring connections because I broke the wiring clips

hi it would be up to you if you would like to give up or not but the clamps do need to be in place with a solid connection to allow proper use of the digitizer. If you would like and have the tools you can try and solder if you have the parts, if not there is always the option of repair by a repair store but it is a kindle and anything after your replacement digitizer the first time may be costing you excessive money more than its worth. So your choice if you want to try and fix it, grab a new one completely, or just leave it alone comes down to its worth and usage.
