OK, First of all, I'm not writing this to promote any sales of this kit. So please don't bash me for advertising or anything, this is actually more of a "stay away" than "hurry up and grab it" kind of review. I have not searched this forum to see if anybody made similar thread regarding this product or not, but anyways I'm just writing for whoever that's interested. Also not a newb, I have past experience in completely disassembling iPhone 4. http://forums.macrumors.com/showthread.php?t=1039511 http://forums.macrumors.com/showthread.php?t=1256629 Where do I start? OK, I ordered the kit for second batch and I received it yesterday. This is what i got Pretty nice packaging First impression? kit looks great! Open up the box and here are the contents OMG, i immediately go into PANIC. WTF is that light panel?????????? Here i realize this is NOT an bolt on kit, sigh........ this is all you get as far as instructions you can watch video for how to install, this is NOT for everybody. Seller does not warn you how difficult the installation procedure is. Their original video on the website is removed, pretty sure because on that original video this kit looked like a 5 min bolt on kit. If you watch the video you will notice you have to tap positive wire (amber color) to power source on the mainboard. This is done with DOUBLE SIDED TAPE!! (OMFG you serious???) Double sided tape also works as a insulation (super multi purpose tape!) and wire is held on by keeping pressure on the EMI shield (you gotta be joking) You already know where I'm going, this is NOT a well designed kit, also NOT install friendly. It took me about an hour of adjustments to get the position the wire and apply correct pressure to the wire to make contact. This will also be problem when there is a big impact, since "LUCK" and pressure is the only thing holding the wire, if there is impact on the phone, wire might loose contact any day. Hopefully I will never drop this phone. yeah, right..... This is very frustrating and NOT fun. After some patients and "LUCK", panel is working fine with the shield close. **side note: I also short out the back light twice, luckily, nothing burned or blew up. After removing the battery and putting it back on, back light came back on... phew!! ** So I'm all excited and started to mount panel and install the rear panel. Here is first look NICE!!! Only took 2 seconds to be disappointed once again. SURPRISE~ SURPRISE!!! panel does NOT fit flush!! Not only that, it has serious light bleeding to camera lens and flash At the moment I saw this I was extremely frustrated... -_- Sigh, quality of knockoff kit. OEM quality -_- additional flaw Comparing 4S, camera lens opening do not line up... as expected modded original I can't just stop here and give up right? So, I started to try out different, I actually came across a fix. As you can see, I applied double sided tape on the rear panel, where the gap was. I also applied foam tape that comes with the kit around the camera and flash. This solves the bleeding and lifting issues. Pic of the fix FIXED!!!!! Final Verdict Do not try if you are short tempered, and a newbie in modding. This is NOT for everybody, and NOT a bolt on kit. I'll probably will use it til i drop the phone hard and light kit looses contact with power source, if that happens, I'm pulling this **** out. Peace!
