Anyone know how to get the front bezel off this thing?
It's begging for a paint job.
Thx!
and perhaps a generous application of rubber cement. I had ONE creek point when i bought it - annoying but livable enough (plus the fact all the bad hours of xmas I was working I never had time to return it in the 30 day period to best buy). now almost 2 months latter theres three...
theres a teardown thread or two on here somewhere but the search button seems to be failing (or my browser....)
- Will.
It must pop off, but I don't want to be the guy to try it...
In the tear down I remember seeing roughly 10 small philips screws holding it from the inside to the metal sub structure. To tighten it you need to remove the back of the device then you will see the screws running around the perimeter. I also remember the screen is held to the bezel with a form of double faced tape.

Its funny because the guy at Best Buy was trying to pull the back off of the one I returned... No idea why he was trying to yank the back off of it...
I guess if he had succeeded I would have seen the screws..
Funny enough the display model NookColor at my local best buy was practically falling off. When I first looked at the device I nearly did not buy one because of that but then getting one in my hands at B&N changed my mind.
The front bezel is a "tape and cover" paint job. The screen is glued to the frame pretty solid. I had mine apart to fiddle around and to get the back off for a mold. Most of the screws are Torx #5 or #6. Tape it off good and you should be ok as far as the front bezel. The rear and metal frame you can easily get to by proper disassembly.
Here's the zdnet guide,
http://www.zdnet.com/photos/nookcolor-teardown/487636?seq=21
Here's what I did.
You'll need a torx 5. After you unscrews the 2 screws by the sd slot, use your nail along the chamfer corner to lift the back siding up. Then use a credit card to lift the back up and run along the edge to unhinged the back.
techboydino, are you going to make a new front bezel? might be a small after market for such things. I'd pick up a more solid one if the price was right.
actually metal front and back pieces would rock...

I would like to see a silicon back cover case that has a kickstand..

I was really considering metal but the fact that most would have to really take special care to actually seperate the bezel from the screen really kind of set me off that. making a case for this is rediculously hard. (compared to my attempts at other devices. if you ever seperated a screen for a cell phone from the glass then you know what I mean. I am trying to replace the back with aluminum and wanted to do a carbon fiber front. so far everything is too thick or just plain looks bad.
Ever heard of masking tape?
3M BLUE painters tape FTW
Glad to find this post!!!
This maybe a little off the subject but does any know where I can purchase a replacement faceplate frame cover.
I accidentally drop my nook color and now it has a nasty crack...
Thank you all in advance!
i took the kickstand off a picture frame...white glued it and had one. Then took it off to fit my new cover...replacement kickstand not put on yet..

Your best bet is probably to pick up a smoked one off EBay or one with a cracked screen and a good bezel.
Actually post up WTB (want to buy) dead Nook Color in the XDA market and link to it in this thread. I seem to recall a couple readers here who have more than "gently used" Nooks....
I started noticing more and more dust gathering under the lens protection "window" but didn't think much of it since it didn't affect picture quality.
Then, after noticing a dark blotch on every shot I took, I saw the glass back pannel is loose in the upper half. The glue apparently came unglued (lol) and now I can easily put a matchstick between the glass pannel and the phone's body, the gap is that big. I tried pressing it back on, but the glue doesn't hold anymore.
Should I try to carefully pull the pannel off, clean out the dust (THERE IS A LOT OF IT UNDERNEATH) and put it back on with some double sided adhesive tape? Or should I take it to a phone service?
Thanks.
edit: How bad of an idea is taking it all off, cleaning the dust and super-glueing it back on myself?

Hello!
First, turn off the device and remove the back cover entirely. Clean the lens with a cotton swab (be careful not to scratch it or leave lint on it ). Then put it back on and heat it with a hairdryer (on highest heat setting). Do it in circular motion around the edges for about a minute. After that(while still hot) grab it with a sheet and start applying small pressure on the sides(slide the sheet on them). Then let it cool and it should be ok. I have done this personally.
Hope this helps you!
P.S. If there is a lot of dust on the adhesive, wipe it gently with a wet rag and continue. The heat from the hair dryer should restore the glue.

No warranty, so I did it myself. It worked perfectly, just that there is still that dark splotch and I made sure I cleaned the lens thoroughly. See the attached picture.
Can anything be done about that?

I'm glad it worked!
About the dark spot: I searched on the internet and it appears to be dust problem. Clean the lens with a windows cleaning solution. If that doesn't work, you can open the phone(heat it with hairdryer using the same method and pull it out with a suction cup) and vaccum the camera module. Then turn it on(without cover) for testing. I hope that is the case. If this doesn't work there may be dust inside the camera module and that is tricky to fix.
You can read this to better understand the problem: LINK
I opened it again, VERY THOROUGHLY cleaned the lens with LCD cleaner fluid, but it didn't seem to do anything.
Anything else I can try?

I'm out of ideas. Repacing the camera is the only thing that comes in mind.
P.S. There might be a way to open the camera and clean it.
I have had this phone for about 1.5 years now and it held up,it was running very well but it always had an overheating problem,you have probably seen me all over the forums asking how can I lower the temperature of the phone lol.
Well it has become less apparent with the latest build of Lineage,only when I am using Snapchat but that doesn't matter.
But now what started happening is my back glass is unsticking,the bottom part to be exact,I believe this is because the device heated up so much it weakened the adhesive.
So I am asking now with what material I can re-stick the back glass properly since I don't want it to hang like that for no reason.
Use fevibond
You can use fevibond(Synthetic Rubber Base Glue). I used it to stick front screen peeling off from top left corner.

Could I use something like superglue or something similar to that?

No, that would make it tough/impossible to separate it for repairs.

Nope I wouldn't do that, as super glue is not flexible. I have glued both screen and back glass with B7000 adhesive (most repair shops use it specifically for displays) and it hasn't moved since. That was done some 4 months ago. If you put enough glue on the frame (be careful not to leave empty spots, cover the complete frame with glue), of course avoid dripping of the sides into the frame, I am sure that it won't peel off again, especially the back glass.
I am waiting for new screen to arrive, so I'll have to re-do everything again, of course with B7000.

Never use superglue, it will not last long and will ruin your phone, as superglue's main ingredient disintegrates plastic...
I've also used red 3m tape, does not hold!
Bought B7000 glue, will use it once my new battery arrives, so using useless 3m red tape in the mean time...
-Update-
B7000 Glue works!!!
I heavily flash, test etc. and no matter how hot the phone gets, it's sealed and does not reopen.
I cleaned the surfaces, I applied the glue, and did not care about making a mess (the glue is easily removable for future repairs) and did not care about it oozing out either, just made sure that it covered that border.
I did not use any heat, and it was still cold here.
I then used clothes pegs, 3 on each edge (I was worried about too much pressure, but it was not an issue)
I did not turn my phone on at all, and waited for 48 hours, before removing the pegs then turning it on.
Please note: the z3c is bendable, especially in jeans pockets, I use an anodized bumper to keep it straight. And using tempered glass on both sides is recommended.
***I did however buy a new battery, as my previous battery seemed fat, and I also removed the nfc sticker, but not sure if that is necessary.
Need to disassemble my Doogee Y6 (not Y6 Max) to replace the USB port.
If anybody has successfully removed the back, some brief instructions would be really appreciated.
Best wishes, Ron.

Sorry for the later reply Monster. Thought this thread had gone dead!
If you've got some tips about how to open the case without destroying it that would be really helpful.
There's a few videos etc on opening Doogees around (Y6 Max etc) but none that I've found for the Y6, which is quite a different case.
Cheers, Ron

So to start take a flat screwdriver. You may turn off the phone it's not necessary. Remove the sim tray. To open the phone read carefully. Don't try to remove the back metal plate, you're doing it all wrong. There is a plastic surround that meets with the glass. You need to insert your flat screwdriver in the corner(I prefer bottom right) of the plastic case/surround and the phone screen must be facing you. Now there is a super thin black plastic that separate the glass and the surround, you need to put your screwdriver between the thin black plastic and the surround (mine is gold). The plastic will wear a little bit but if you do it properly, you won't notice any scratch or paint damage. Put your screwdriver in and pull it apart trying to lift the back cover. Don't be scared but be careful, go until you hear a click then you may use your finger nail or the screwdriver and pass it all around the phone. You will hear many clicks. Don't be scared for the fingerprint sensor because it is stick to the phone. After having done that for the first time you will be able to open the phone like previous phones used to be, that is removing it like a removable back cover using your fingernails. I hope I could do a video. Tell me if you did not understand a thing because I can use my phone only on Saturday and Sunday( exams are near).

Brilliant! Thanks Monster. For me you provide a remarkably clear explanation. Used a very small, flat bladed jewellers screwdriver to lever the black plastic surround away until it clicked, just as you describe, then used an old credit card as a helper, to slide along the gap, to separate the metal back from the rest of the phone. Now just need to figure out how to actually make the repair!
Very best of luck with your exams. (so glad to be largely done with such things!)

A video would no doubt be tremendously helpful to others anyway.
The problem with the phone is the micro USB socket is stuffed. The plug is loose and difficult to get a connection, due to continual pushing on it by the USB cover flap on the flexible plastic case that came with the phone. Have cut the flap off but the damage has been done (warning to others!).
At first glance it looks like the circuit board will have to come out to have any reasonable chance of de-soldering the socket.
Cheers Ron.

I would prefer replacing the charging board itself. Changing the USB connector seems difficult for me. I can do a teardown video but the problem is the camera. I only have a Samsung galaxy core to make video as I can't take the y6 itself to make a video. The galaxy core does not support focusing while filming and the videos turn out blurry.

Great advice, makes sense. I now see that it is a separate board and that there are several sellers of Doogee Y6 charging boards. So the plan now is to purchase and try to replace the board, perhaps also replacing the USB connector on the old board as a spare.
Do you know if the ribbon cable(s) have a lock, or does it just pull out? Although a video would have been great, some basic advice on removing the board could be a life saver.

Hey I opened the phone and checked the flex cable. It has a lock hidden under some cover, cloth like material. I'm sorry it I won't be able to do a video because it is super blurry. Now that u know how to open the phone you have to unscrew 4 screws at the bottom. After that gently lift the plastic cover because you may damage the speaker and/or the vibrator. You will see the speaker is actually low quality. As for the charging board, it's pretty easy to remove. Once you remove the plastic cover open the lock by gentle lifting the flap and disconnect the cable. I think that you will need to remove the battery too because the cable is too short and maybe be tricky for you to remove it. You must be really carefully when removing the battery. Take a flat object( I used the same flat screwdriver) and try to lift the battery. Make sure not to puncture it. There's a lot of glue underneath. When you remove the battery then it will be easy to remove the cable. There is two clips holding the board in place and you will need to move one of them to take out the board. Mime is a bit damaged but it's OK. The plastic cover protects it. Don't hesistate to ask questions if you don't understand. Thanks.

Brilliant, thanks again! No need for a video, as your explanation is very clear and should be obvious to others after they get the back off the phone. Having recently removed a glued battery from a Kindle, it was a hell of an arm wrestle! Hopefully it will be a bit easier with the Y6. I have a flat nylon spudger with a rounded edge, which should be able to lift the battery without puncturing it. Upgrading the speaker at the same time could be a useful hack, if a better one can be found that fits. Although don't know if the impedance is the same for most phone speakers.
Will post results here including any lessons learnt. Cheers Ron.
The replacement usb charge board arrived, purchased from this guy: http://www.ebay.com/itm/New-Origina...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649 Posting the url as the service was excellent. Very well packed in its own cardboard box and sent by registered post. So I would buy from him again, even if he is a little more expensive than some on AliExpress.
To fit the new board, the case was opened, as described above and the battery removed. To remove the battery, two screws need to be removed from a metal plate covering the battery connector. The battery ribbon cable connector can then be levered up with a small flat screwdriver blade. It's a effectively a plug with a push fit onto the connector so just pops off.
To remove the battery I used an old credit card, sliding it underneath at one edge of the battery, then gently pushing it forward to release the battery bit by bit, from it being glued to the base. This shouldn't need a lot of force and it is important to avoid snagging the ribbon cable that runs under the battery.
The black plastic cover that houses the speaker and covers the charging board was then removed by unscrewing 4 screws. On my phone one screw had a white plastic covering, into which a cross head jewellers screwdriver can be pushed to grip the screw. The charger board was then exposed and the two speaker wires and two wires from the vibrator were unsoldered using a fine tip iron. The plastic cover was then fully removed. The black rubber tape covering the ribbon cable connector was scraped away, the connector unlocked and the ribbon cable removed. The antenna connector attached to the charger board was then levered off using a small flat bladed screwdriver. The charger board itself was then pulled out. It is held in place by tiny plastic tabs on either side and was a bit of a fiddle to remove.
The old charger board has some Kapton or similar tape underneath, which the new board didn't have. So I applied some similar tape to the new board, but this may not be essential. The new board was then fitted back in, again a bit of a fiddle. I found the best way was was to insert the right hand side of the board first under its tab (looking at the inside of the phone from the charger end), with the board rotated slightly anti clockwise, then pushing the left hand side forward (rotating clockwise) and under the left hand tab so that it effectively clicks into place (not much of a click). The rest of assembly was the reverse of disassembly. Soldering the 4 wires (polarity is marked on the board), pushing the ribbon cable squarely into the connector and locking it. Nearly forgot to push the antenna connector back on!
Replaced the back and the new charge board worked perfectly. What a relief! Thanks again to Monster for getting me started. Cheers Ron.
Hello everyone,
I have every tool needed to fix any problems on any mobile phones. But after fixing my y6, I have thought that a T5S would be piece of cake. But it's not.
Any ideas if I can just remove the broken digitizer to attach the new one or is it glued to the LCD like all new Samsung models?
Hi guys,
has anyone of you tried changing the front glass without digitizer and display?
In disassembly videos I can only see people changing the whole thing.
Also, do you think I can manage to repair the front glas as well as the USB port with just an iron instead of a hot air blower (and the usual tools made of plastic)?
Thanks in advance!

I haven't done the front glass on mine yet, but my understanding is that in general you're really better off replacing front glass as an entire unit with digitizer and display. An iron on pretty low through a cloth/towel might well work. It's not just glue that melts, it's a thin strip of rubber gasket material with adhesive (okay, maybe it's thick glue, but it looked pre-formed to me) holding the glass back cover on.
Heating probably helps a bit with softening the stuff, but after the first time you peel it up you won't really need to do that again. I'd recommend picking a corner (say, bottom left as you're looking at the back) and just plan on prying from there every time, so you only have one spot where the plastic gets marred.
Don't spend too much time heating, worry more about having a suction cup tool that you can lift with while you try to work a guitar pick or hobby knife or something in under the corner. Have at least two ready, so you can wedge one in, and work your way around without it just dropping back down on you. You'll probably tear the material a bit but that's okay, just spread it back out evenly around the edge on the glass before you put the cover back on. Also, you definitely should be using a case to make sure it doesn't just fall off in your pocket once you've opened it up a couple times.
USB cable replacement isn't awful, just time consuming. The biggest gotcha is to keep all three of the little gold clips on the plastic "mid frame" ring (that's the first thing you remove that requires screws after getting the back glass up) from fallling and getting lost.
You can PM me if you have any questions about this, I've replaced my USB cable/port assembly a couple times (first replacement was defective). And I'm about to attempt replacing the screen as a whole unit with glass & digitizer on my wife's Z2 Plus, so I'll let you know how that goes.
