![]() There are very small plastic pins on the four corners that you don't want to break off. Try to lift it evenly on all sides, keeping it horizontal. Apply heat if necessary, but be careful the light guide is fragile. ![]() Start at the bottom of the screen were the adhesive strip is the largest. You need to work from the inside out, sliding your tool between light guide and screen. Now it's time to remove the light guide from the screen. If all goes well you end up with the front cover completely removed.Ĥ. You need to push in between front cover and light guide (aka bezel, but I'll stick with light guide) until you reach the bump of the light guide. This time you will need to reach further inside. Go around the outer edge for a second time. You might get stuck as the adhesive cools down again, so add some heat.ģ. That's normal and will only happen in the next step. You only need to go 3-4 mm deep to split front and back cover. Make your first opening all around the outer edge of your reader. Try to find an opening between front and back cover with your thumb nail or plastic card. Before the front cover gets too hot to touch it with your bare hand switch off your heat gun.Ģ. Use one hand to feel the temperature as you go. Gently heat up the front cover all around to soften the adhesive. One sheet of A4-sized 3M 300LSE double-sided adhesive (5€ on ebay / aliex)ġ.Mine was ED068OG1 (about 30€ on aliexpress) Always check the part number on the ribbon cable of your old screen. IPA to clean the surfaces before putting on new adhesive.WD40 and paper-towels to clean off the adhesive (if you know about a better solvent I'd like to know.).Not strictly necessary, but makes it much easier. Some kind of heat-gun to soften the adhesive.An old credit card-shaped plastic card cut in half lengths-wise.That is what makes changing the screen so difficult.

I am sure there are other ways to do it and comments and corrections are welcome. I thought I could post a little step-by-step in case anyone needs to change a broken screen, not wanting to go through the whole learning experience. To change the screen was easy, but even after a good dozen of tries I couldn't get the touch screen to work properly and for a device with just one button that is a no go.Įventually I gave up and felt bad about it ever since, until I got another broken H2O on ebay for parts to start over. Well I made my bet without knowing anything about infrared touch screen technology and the wonders of water-proof assembly with double-sided tape. By that time I had successfully repaired an Icarus8 and several smartphone screens and I thought the most tedious part would be to wait for the new screen to arrive from China. I hope I'm not stepping on anyones toes.Ībout a year ago I agreed to fix the broken screen of a friends Koko H2O. Office custom explained it is software issue.This is my very first post ever.

From the "Device information" screen of the settings.There are three ways to initiate a factory reset on an Aura H2O: You do not need to use the PC when doing a factory reset. I must return to factory maintenance device? If anyone I encountered this kind of problem for KOBO aura H2O? So i can not use manual methods to restore factory Settings. Through the USB cable to connect the computer, the computer can not find H2O DEVICE DISK. While I use a USB cable charging process, the power light is flashing.īoth the initial charge, and the initial boot, the screen is flashing white and black, and then there are the blank screen. The happening of the problem only lies in the system update process is canceled. ![]()
