I totally agree with Michael R and I am waiting for a iPhone 6 4.7" mould - I prefer to work with a mould. The 2 critical parts are the 'removing' of the shattered glass and the LOCA glueing. I did give a good try one and a half years ago and it was 50-50 = BAD, but I saw it was doable with practice. But in the last few months I am getting back and self-train myself to find the best method 'for me'! We all are different and something simple for me, might be difficult for others and vice-versa. It is the same with Tools, often I make my own special ones! The fact you need to keep it 10-20 minutes in the Autoclave, tells me all I needed to know and you can still get bubbles. Glad you confirmed my suspects - the ££££ tools to do the job 'supposedly' professionally is one of many other flops and a marketing tool to sell not-necessarily-needed equipment. Look at many Soldering Irons etc. around - you DO NOT need 90% of them and it all depends on your 'innate' [you were born with] abilities and of course you can...
... or we could start a Government Petition to make Laws on imported Mobiles and Tablets to have 'cheap enough' spare parts FROM the manufacturers, like it used to be with ANY electronics! Let alone they do not give schematic diagrams anymore! I am talking in general Electronics and Hardware parts. Oops, too democratic and not Business like?
or Simply get a faulty LCD and experiments yourself. That way you will know for certain, without school - the Scientific way - small changes, write them down and see what happens! Of course there might be differences depending on maker, etc.
Me too is interested in this OCA, rather than LOCA. Is this thread dead? It seems strange! I 'attempted' it too and yes LOCA is a messy business and also makes you work a lot for the same profit. I believe 80% of the tools advertised to do it are un-necessary really, maybe if/when the business picks up THEN it might be worth buying automated and better gear. Anyone wishes add anything?
Actually I had the same problem and tried 2x compatible ones - only 'cracked and taped up' original works! LCD too - Apple firmware must have been updated with IOS 8.02 to stop you using pattern spares!
