    • Use a guitar pick or similar opening tool to unsnap the touch window assembly from the support frame.

    The last step is missing. You will have to remove the digitalised from his frame by slightly unstick it all around the frame. Take your time to avoid braking the fragile frame.

    Where can you find a reliable screen? My glass isn't broken, but I can see the cracks underneath. Would this be the same type of replacement as described in this tutorial or something different?

    Nicole - Antwoord

    They say to separate the screen from the frame you should try to use a hairdryer to heat the adhesive so it comes apart. If you want to buy a new screen & tools, you can try aliexpres but PLEASE remeber to check the reviews and number of orders... This is the one I'm waiting for : http://www.aliexpress.com/item/100-New-O...

    in the step 8:

    you forget to replace the sensors from the old touch screen in upper left part of touch, right to place of vibro-motor...

    auroryus - Antwoord

    Don't mean to sound stupid, but I do not know much about this phone. My screen is slightly cracked and it will not respond to touch, is the cracked screen why? I just bought it and screen got cracked before use. I know several people that have cracked screen and they use their phones. Wanted to know before I bought the replacement.

I used a t5 screwdriver and it worked perfectly :D

tnx for the guide!!

Probably one of the easiest repairs i have ever done, tip pay, an extra few pounds and get the digitizer with the frame.

adrian lunn - Antwoord

Hi Adrian, where did you buy the Touch Windows? I asked Nokia but they do not sell it..

Thanks.

The last and hardest step is missing---separating the digitizer from the surround. They are glued together and you basically have to destroy the glass to get it off. (See the teardown for details.) Other than that, a great guide, thanks.

joe - Antwoord

Well... you're trying to replace the glass in the first place, so it's technically already destroyed.

Also, I broke my Lumia 520 screen and I'm waiting for the replacement screen to arrive. If you use your thumbnail or something very thin but strong, you can separate the glass from the frame without causing more damage to the glass by running it underneath the edges of the glass, all the way around.

Granted, it took a couple of goes to separate them because of the glue, but it did come off without breaking either the frame or the glass.

Choi Nxiella -

It looks very workable, but, like Rodolfo, I can not find where to purchase a new Touch Window.

I found a replacement glass for the nokia 520 on ebay. Do you think that will work on the 521 also?

Patrick Kelly - Antwoord

Great guide, unfortunately after I replaced the digitizer back into the surround I cracked the top corner whilst clicking it together, so back to ebay it is. :-)

Stu Page - Antwoord

Make sure you buy the digitizer and frame at the same time because it is very difficult to remove the digitizer from the frame, it can be done but I damaged the frame slightly.

Phil - Antwoord

Worked very well am a 70 year old would have been lost without the guide.

Many thanks

Very self explanatory , fixed my daughter's phone in a snap with no problems ..... Woot~Woot !!!..... Thanks....

Yes, T5 is the one for the back screws. As with comments above, this otherwise useful guide doesn't cover removal of old digitizer from the frame. I would say gentle heat from hairdrier, and prise up corner with a thin plastic-edged tool and run down the sides - carefully! Heat as you go until glass is removed. Old glue can be cleaned off with cotton bud and methylated spirits, which usefully doesn't melt or discolour most plastics. Its worth getting the inside edge even to avoid possibility of cracking new glass when pressed into position. The back of the new digitizer has a film that is pulled off to reveal the adhesive edges. Once it's lined up in the frame from the front, I found it useful to press the the frame home laid flat, screen down, on a table and working round the edge.

Stuart Goodall - Antwoord

This is a good guide. I would just like to add my tip.

Use a hot air gun to separate the screen from the frame. This heats up the glue and makes separation fairly easy.

DON'T FORGET TO MAKE A HARD RESET IF YOUR NEW SCREEN DOESN'T WORK

ADD IT TO THE MANUAL PLEASE

Really awesome guide. I appreciate the time you took to take those shots and put it together; it really cuts down on the time (and guesswork) it takes for me to repair something. One thing -- those are Torx T5 screws, not T4. The T4 bit I was using almost stripped the head of one of the tighter screws as I was trying to remove it.

It's pretty amazing how simple the inside of a phone looks these days.

"The last and hardest step is missing---separating the digitizer from the surround". Joe's comment is true. This step is not there. And in my case, my ebay order did not come with the 'surround'. I had to tear off the old surround and somehow stick into the digitizer. And it worked!

I had mine replaced by an Indian guy in a small shop. However the alignment of touch versus icons is a bit out. How is this re-aligned? Software function or what? Maybe 'made in China in a 'ell of a hurry - keep in a cool place' as we used to say in the old days...

aleonmare - Antwoord

I dont see any reason to seperate front glass from the digitizer frame. Way too much work for few euros to be saved or what ever your currency is. Also if the front glass is cracked you cant be sure if digitizer works fully or you damge it at trying to remove front glass.

arvid asentaja - Antwoord

Hey there, i have a phone like that but the actual phone screen is frozen and a bit cracked... I took off the protector glass to check if anything was wrong with the protector but there was nothing wrong... Is there any possibility that it could get fixed or work again? Just wondering :)

tori banks - Antwoord

Great descriptions! Seemed to work for me, used the hair dryer method to extract the glass screen from the frame. Note that the touchscreen did not work correctly until the screws had been replaced. :)
