cables that fragil and are mainly a plastic with either a conductive paint or copper cladding is not a repairable thing other then replacement, a few have suggested searching ebay as you can get a replacement screen cheap this may also apply to getting the cable only if it's detachable. but believe me I've tried this and i'm great with surface mount on the PCB direct soldering on the ribbon is possible but the wire type adn tools needed out weigh the cost of the LCD used or new

Change hard casing...

Hi all
my elfin fell from quite a high place, and the four casings into which the small screws visible when you take off the back cover are broken...meaning the front casing is loose too.
do you know where I can find a front cover (I don't really need the back but I'm okay with buying both)... but before that I was thinking maybe someone could have bricked their elf or had an unusable device but with a front cover that's ok...
thanks in advance for your help !

Plenty of covers in a selection of colors on eBay, I suggest you try to find one there. Not that expensive and you can buy a digitizer to match the color.

hi
thnx for your answer . what's a digitizer?

Digitizer is the outer screen cover attached to the faceplate that is responsible for touch function, the one you use your finger or stylus on. It's sold separately and is fairly easy to replace in cases when the touch function is lost or the digitizer is broken. You can get one to match the color of the housing for a complete look. Just look on eBay and you'll see what I mean.

oh... does that mean that the part responsible for touch function is actually stuck to the front casing and not to the screen itself? I hadn't thought about that... meaning I cannot jut change the front cover, I would have to replace this as well...
[edit] is it possible to use the one from my phone? cause it's working fine after all... I'm looking at it and I don't really know how to take it off...

The digitizer is attached to the housing and in your case needs to be pried off before being used again and re-attached to the new housing. The digitizers are fairly cheap (the reason I don't bother with screen protector), so you will get unscratched and new one that you will have to attach to the new housing. My recommendation would be to buy a new housing and a matching digitizer.

Hi
thnx again for your help. I have one more question. Is the digitizer stuck to the screen or is it the actual hard plastic screen?
I find it's actually fairly expensive. When you add up the housing + the digitizer + the shipping costs it adds up to quite a lot..
[edit] Ok I think I finally got it now.
what do you think of this product ?

Replace Chrome trim on SGS2?

I'm trying to find a source on whether I can replace the trim know my phone since it's been dinged from the previous owner as well as myself.
I've found some the link to the replacement screen thread but it doesn't say if the lcd is part of the top or how to get it out? I've seen some oem housings online but not sure if I can remove my lcd which is fine and put it in the newer housing?
Is there glue or adhesive that holds it in?
Thanks for any help.

You just need to unscrew the backplate and exchange it.
No glue no adhesives or something. it just sits there.
It will take about 10 minutes or so..
Here is a picture of the part:
Mine fell out of its place, the last i had the phone opened and i´m to lazy to put it back.
Edit: sorry for that huuuuge picture.. blame our 8mp camera.

Sorry - but I think we have a misunderstanding. I'm talking about the chrome trim around the entire LCD not the camera.

oh.. honestly i don´t think that the part you described is chrome. Atleast not on my GSII
and the thing i posted is the shiny ring around the headphone plug.

OP its not chrome its plastic..
1) replace the whole screen housing with with working parts from say ebay
2) buy a whole SGS2 housing unit and plus top screen ( this option you'll need to remove youe current lcd screen and once replaced in new housing the top screen needs to be bonded to housing. (M3 double sided tape or a thin silcon glue)
3) take it to a service centre
4)keep it as it is..
as par your question
Is there glue or adhesive that holds it in? Yes.
Top screen will need to be heated with hot air to release it from its bond.

Thanks - that's what I wanted to hear. So it's more effort than I'd like to spend on it. Looks like I'll just move the phone to try something else.

Hi mate!
I have one brand new that I bought but never installed.
For your information I can advise you that you cannot change that single piece due to construction of the Galaxy S2.
I can explain you why telling my story. My Galaxy S2 went to bath and home button stopped working, so I realized I needed to replace the capacitive and home button flex module as it got damaged. I bought one original piece from a German seller on ebay and tried to replace it with the damaged one. I can assure you I'm very expert repairing phones and I know well our beloved Galaxy S2, but due to the very thin construction of the phone, the glass is glued hard to the LCD and the home button ribbon cable is between these two pieces, as you have to detach the glass from the LCD to reach it.
Why you cannot change it? You cannot detach the glass from the LCD without breaking the screen as it is truly very thin, imagine about 1mm thickness or less. As the glass is glued very hard to the screen, you cannot distribute the forces when detaching it and you'll end breaking the screen with 90% probability. I broke mine when trying and I did the whole process very carefully, knowing it was very fragile.
So, if your home button or your capacitive keys stopped working I would not recommend you trying to change it as you'll have 90% chance of having the LCD broken too.
Sadly, you'll have to change the whole front module (glass, LCD, front bezel frame and of course home button cable, all included). It's a very expensive repair, but the front module is very easy to replace and you can do it on your own.
I bought one genuine like new without scratches from a salvage Galaxy S2 from Samsung repair centre for about 80,00USD. I can give you the link if you want to buy one too.
Sad to tell you this.
Hope it can help you.
Cheers.

[Q] Screen replacement - volume flex cable. PLEASE HELP!!!!

Hi,
I just attempted to repalce the screen of my E975. I bought a complete replacement assembly with housing, to make things easier for myself.
However, on the original phone there is a little metal plate where the volume flex cable connects to the motherboard. On the repalcement part, there is no such thing(see pics). I took the volume flex cable and moved it to the new screen assembly and put a piece of doublesided mobile tape on the replacement part, to make it hold and elevate the connector to the same hight as with the metal plate. But now my volume buttons arent working anymore?
Has anybody had some similar problems or could someone help me out how to get my volume buttons to work with this new screen???
I looked everywhere, and all the complete screen assemblies you can buy for the e975, look just like the one i got. So there are none that have that metal plate?

I have the same problem! I thought I broke the flex, so I bought a replacement, but it doesn't work either. ¿Did you resolve it in anyway?

Hi ! I broke the lcd on november haha, I ordered a new assembly lcd. Please ask me your problem, I dont understand that hehe. I think I could help you ! Haha
PD: Works volumen buttoms !
Please give a better pictures

The little metal plate is supposed to sit on the flex volume cable. Turned out i had separated it from the volume flex cable when disassembling the phone.... I bought a cheap replacement volume cable and that did the trick
