Thanks everybody for this documentation! I've finally done it yesterday, using epoxy.

My advise: get someone who knows how to solder to do it for you if you can't. And try practising soldering on something else first (didn't help in my case though).
Epoxy was easier to apply using a needle (and no risk to melt components like with soldering), and no need to round any corner or to cut any piece of plastic to put the cover. I advise everyone who don't feel confortable with soldering to use this method.

If you don't get it right, the bottom side of the monitor sticks up (and if you power up the phone, there's a dark spot on the monitor during sliding).
I had the same problem during the reassembly. I couldn’t put it under the keyboard, so I screwed the screen first, and then I put the keyboard under it.

However, I have an other problem: for me the more difficult part of the manipulation was to reassemble the screen to the back part: there is a flex connector back the screen, who needs to be replaced exactly onto the corresponding chip on the board. Does anyone have a method to do it? I have been very careful with it but it seems not to have been replaced correctly: this morning it worked but now the phone works, the led works, but the screen no longer works. I have to reopen...

Furthermore, during the disassembly, I noticed there was an oxidized stack (there is a type of green acid on it). I think it's the reason why when I remove the battery and reboot the phone, I always have to reset the date and region. May it cause trouble in the futur?

edit: I have reopened it once, and I still have the same black screen problem!

final edit: IT WORKS! I've noticed there was 4 pin at the corners of the flex connector, that must be put inside the corresponding notches (slide open it's easier, with the edge of the screen along the keyboard like there or there). It's quite meticulous (I've re-open 4 times), because it's not realy hoocked.


DONE!
