Hello everyone, I've searched all over for an answer to this one with no joy.
I've had my stock Orange locked Diamond for almost two years now, and towards the end of a family break I dropped it.
Now it won't switch on beyond an initial buzz, and none of the mini USB chargers or pc cables will persuade it to charge.
The problem is that I used it to take all the photos during the family break, and now can't access them.
Now I read the reply about "jump" charging the battery and will be giving that a go, but can the memory chip be accessed independantly to offload the contents?
I should add that for quite a while before, the phone picked up and dropped the usb connection when connected with a frequency of about 3 - 5 seconds, which was very annoying.
Many thanks in advance
Luke
Little update
Hello all, thank you for reading about my plight.
Well I managed to charge the battery, and I think the phone switches on, as the volume controls make the appropriate sounds. However the screen is black, and even under heavy sun I can't see anything, so it's not just the backlighting that's gone.
The pc doesn't notice it when I connect, so I can't get in that way, unless someone can point me to how to chop up a cable and hardwire a data connection "upstream" of the mini-USB socket? (I'm hoping it's just the connector which is dead)
Otherwise, is there a combination of hardware buttons that will switch on bluetooth? I dropped it when it was in airplane mode. I had BT explorer checked, so if I can get BT on, I should be able to browse the phone with the pc? Please confirm.
Looking forward to reading your suggestions
Cheers
Luke
ps now I've discovered the limitations of a fixed memory; if the card were removable, all this wouldn't be an issue.

Thanks, I'll give it a try
Hi, thanks for the tip, I guess I have nothing to lose.
I've just found an appropriate screwdriver so here goes.
I saw that thread, but as one of the symptoms involved actually being able to read something on the screen, I didn't pay that much attention.
News soon.
Cheers
Luke
ok let me know.. best of luck
OMG it worked!
Hi, fantastic tutorial.
It took me several attempts to realise that when you say "chip" you mean circuit board.
Pressing and pressing gave no joy, but further investigation showed that I could slip the screwdriver underneath the loose connector and engage it from there.
Yes bad design on HTC's part, there should be some sort of physical lock, or at least a block underneath that pushes the connector into its socket.
However nice the phone was, the WM6 bugs & glitches were annoying, the USB connection still doing that really annoying thing of connecting and disconnecting every few seconds, so it's going to be hard to retrieve the photos; GRRR!
Does anyone know of a program that can block send files from the phone, either over wifi or bluetooth??
Anyway, many many thanks Siddharthsai, at least it's up and running. I doubt I'll be using it much now, despite that superb screen, my insurance replaced it with a Desire, and I have to say I'm impressed with my new toy
Oh yes, where's the command for auto screen lock? It's annoying me.
Many thanks again
Luke
Getting there
OK so thanks to Diamond tweak I was able to stop the screen locking every 5 seconds.
The USB problem is mechanical; I forced the phone down onto its mini USB plug really hard and it stayed connected. Thanks to SuperCopier 2 I was able to dump the contents before my hand got cramp
Yippee.
So I've got TomTom on the diamond, but no on-board nav on the Desire. My diamond might just end up relegated to being the permanent in car nav unit.
Anyone got a fix for the dodgy USB problem? I've tried all 3 of my mini-usb cables, but they do all happen to be HTC oem.
I guess that's why the micro USB has been adopted.
Thanks

So, I bought my wife a nook Color. She's an English teacher and she's embraced technology as a teaching aid, so I figured it would be perfect.
I did not modify the nook AT ALL. All I did was put some ebooks on it from around the web, loaded onto an SD card. Nothing unusual beyond it being a few THOUSAND files in .epub and .pdf format.
ANYHOW, she's seen issues.
First, she saw issues where the nook thought she was tapping constantly in the exact same spot. To be exact, the spot where the 'b' is. If we hit the nook home button, it kept clicking the book that was in the exact same spot as the 'b' button was. Shutting the nook off entirely fixed it.
Second, frequent lockups during normal use. Sometimes in the browser. Other times flipping through PDFs. Android itself usually wasn't locked up since we could hold the power button and get the dialog asking us if we REALLY wanted to shut it down, but the nook overlay GUI was certainly dead to us. Again, a hard reset (power button until it shut down) and power up fixed this without a problem.
At this point, we thought it would be a good idea to swap this out as a potential hardware issue. We bought it from Best Buy, so back to BB we went and swapped it out for another nookColor.
Now, we're seeing more issues, but different ones.
Third, the power cable doesn't seem to want to fit properly into the USB port like the last one did. A little play and it slides in ok, so no big deal.
Fourth, buttons are sensitive to where it thinks we tapped twice. I don't think this is a real issue since it's a matter of learning the device I think.
Fifth, and fairly important... this only happened once. It lost all sound. We have a child who's just over 1 year old, so the B&N's stance to try to set a high focus on that aspect was awesome, especially the childrens' books with the professional voice actors.
Now, it's my opinion that it's just an OS that was released prematurely. I think many of these issues will be fixed with the first update. Am I alone in these issues? Has anybody else seen anything similar?
For the record, I've taken a very hands-off experience with this since I'm extremely technologically savvy, and I wanted my wife to be able to run it without needing me there. None of these issues have persisted throughout a shutdown-reboot except for the sound issue. It required an 'erase and unregister' through the device info in settings.
I bought a NC for myself and a day later my wife bought one at the same B&N. The one she bought had terrible screen flicker so we exchanged it for another. The second NC would FC on her ebooks, drop wifi, and would make a cheap plastic creak when pressed to tight on the left side. Thinking the bad batch idea we exchanged the NC at a different B&N and the third one had the same screen flicker the first one had so we turned around and went back and exchanged it for a fourth one. Finally. The fourth one worked fine and does not creak at all.
I wouldn't necessarily say your problems are OS related. Android has been running on a lot of portable devices for quite some time now. I think it can be considered a mature OS. The ebooks we have that caused the second NC to FC work flawlessly on my NC and the new fourth one. Rebooting the second NC didn't help with the FC'ing and wifi dropping. So we felt the problem was hardware related like the screen flickering. Our feeling was we didn't want to mess around, it's $250, we were determined to keep exchanging until we found one that worked.
You might want to think about exchanging it for another. Who knows how many will remain to be in stock as the date gets closer to Christmas. I wouldn't recommend trying to exchange it after Christmas, you may end up getting a re-shrink wrapped one that was returned for some unknown reason.
android is becoming mature but the nook is oem'dto death. This os is crap by all accounts! Once something better is available we will see improvements
The screen thing is turning out to be kinda common.
Good news is.... its being blamed on an oversensitive screen, dirt and or moisture. Any tiny bit of the latter two. Usually fixes itself right up with a wiping or a screen protector and a lock/unlock of the device.
I have experienced and read about the charger cord too.....have yet to see any problems because of it but do worry about having to re-solder something sooner or later.
I have to wonder about the usefulness of a Nook Color as "a teaching tool" right outta the box though?? Besides making your wife a walking reference that is.
was it plugged in? There are issues when plugged in and tapping.
I also had to "wiggle" the USB cord to get it to fit into my Nook as well.
I had the creak on the left side as well. Haven't had a chance to exchange it yet, but it's on the radar.
I don't mean a tool to use with the students, I figured it may make things easier on her if she's got ALL of the books she uses with her students on a single table that she can carry around the classroom referencing instead of needing 30 different books. I don't know if it was a fool's idea yet or not! It's the thought that counts.
Defiantly save on the back!!
Nice one, guess I just want mine to do everything
Galaxy Tabs.....Worth every penny!!
My first nook had the sound problem, except it would happen every 15 minutes and only hard reboot would fix it.
I replaced it and the second works flawlessly (as far as I can tell).
Hey guys i just bought a nook color and had it shipped to my country but i think i am already regretting it now.
The touch screen starts behaving very weird randomly at any times, it automatically registers touches and keyboard automatically typing own it own, and what ever i touch just goes straight to hell and this continues as long a i don't lock and unlock it again.
Even when i am reading it automatically starts zooming.
I was think about rooting it and installing a custom Rom, will that fix the problem? because giving it back to B&N is not an option for me.
Also i don't have screen guard, and the screen is always smudged with fingerprints, can that trigger this sort of behavior?
I'm using mine in Australia and have a similar problem but only when using the supplied USB cable to charge it.
I've heard stories about faulty USB cables which might be the case as I don't have this problem when I use the cable for my desire. The problem with this is that the cable isn't long enough for practical use and the supplied cable apparently has extra pins which would explain why it still discharges (although slower) when using my desire micro USB cable.
For now I'm limited to only using my nook without the cable plugged in but I'm thinking about finding another cable as sending it back to B&N and then paying to ship it back here isn't really a viable option.
Let me know if you figure something out though.
Well the one with usb cable is a known issue and u can still use it otherwise, mine just happens randomly at any time, its almost unusable.
Does installing a custom rom help?
It wouldn't hurt to try. I know some kernals make changes to the touchscreen sensitivity but I don't know whether that would apply to your problem or not. A nook is very easy to un-root anyways so as far as I know (and don't quote me on this), you should be able to return it if you absolutely have to.
Don't give up though. I'm loving mine and for the price it's an awesome little accessory when it works.
Hi,
Make sure to clean the touch screen - last night I had a different looking
smudge on my screen that was causing huge problems - as soon as I cleaned
it off, back to normal. Are you in a humid location? Condensation will cause
problems too.
Also you may want to search for 'calibrate' in the forums, there is a way to
recalibrate the touchscreen sensitivity, I believe that this is mostly for
low sensitivity at the corners though.
Here are two links I found:

My touch screen acts up as well. I turn the screen off for a couple minutes to "reset" it. It will work OK for a little, then it goes back to wonky.
Hey guys i finally found a solution to this problem, well my touch screen is behaving normally when its not not connected to the power cable. I hope thats a solution good enough for you.
Just go to
h**p://nookdevs.com/Recalibrate_the_NookColor_touch_screen
I tried all the custom roms but that didn't help very much, so i tried this on CM7
and so far my screen is giving totally normal tests results when not plugged in and lets hope that it stays that way.
My daughter had a similar wonky-screen problem when she plugged in a particular set of portable music player speakers. Not another pair she has, just that one.
And I was able to replicate it on my nook. It wasn't specific to her nook.
okay, it seems that my excitement didn't last that long but
After a lot of testing, it turned out that the only problems was my oily or moist fingers.
so i got a screen guard and tested it for more than two hours and i haven't had any problems yet. So even if i do see that happening again, once in two hours is not that bad.

Hey all! It's been a while since someone posted any vehicle install pics in this forum, so I thought I'd catch you all up on a little project of mine. I started it earlier this year, but now have it almost completed. Some of this was previously posted on another forum, so I apologize in advance if something doesn't make sense or seems out of context. I'll fill in any gaps, and answer any questions you may have.
I started with a car dock for my phone attached to a Bracketron mount. I'll be able to tether the phone's internet access with the Android tablet I'll be using as a head unit.

I'm going to be using a rooted Nook Color, and in order to fit it in place, I needed to move the HVAC controls. After pulling the center bezel off and looking around, it appeared that the controls could be moved down after a little cutting and duct modification. Here is the end result after fabbing a pair of new brackets. I've still got to make a new surround to fill the gap.
In addition to the Nook, I'm adding a Hifonics HFEQ. This will allow me fine control over the signal being sent to the amps. I can switch between inputs and use it as the main volume control.
The approximate position of the Nook...
I'm using a tablet mount from RAM, and I've got to figure out a good way to mount it. That's coming up soon!
Now one last thing. I have a bluetooth OBDII reader installed for the Nook. I reversed the plug and bent it up slightly to keep it out of the way. I'll be able to use an Android app called Torque to read all relevent Jeep data.
Update time! I needed to get the Nook mount in place, and modify the center bezel. I had a lot of options when it came to mounting, but I wanted to keep it simple, and by default reliable. If it won't take abuse, it's not worth putting in a Jeep. So, I decided to utilize my existing Quadratec iVault. It has served me well for the past year or so, and now it was getting a few more holes... The idea was to eventually make a storage compartment behind the face, and use the face itself to hold the RAM mount. Now, I do realize that nothing is ever truly safe in a Jeep, but there are times I need to stash something quickly while running in to a store. The Nook itself would likely get put in there.
So, let's start with the mods. Due to the mounting points in the RAM, I needed to move the existing iVault lock to the left. I drilled a hole, and shaped it with my Dremel. This was the result.
Now I needed to make a few holes for the RAM mount.
Now finally the mount and iVault face are bolted together.
It was time for a test fit. As you can see, it attaches nicely. Now one could argue about the aesthetics of it's spacing away from the the bezel as it is, but it works well for me. It's within easy reach, and most importantly, nothing is blocked. That was a priority here. I've seen installs where the vents are unusable, or the HVAC controls are inaccessible. That may technically work, but I couldn't live with it. There was no way I wanted to sacrifice any function just to do something cool. That's also the reason the Nook isn't more tightly integrated into the bezel. It needs to be easily removable, and make for easy maintenance should it be needed.
Now, let's take a look at the Hifonics EQ. It's very easy to use in this location, but I'm not sure the pic is doing it justice. I have to do something about the gap above it though. I can't just shove a fill plate in there and call it good. I've got to fix it the right way. You can see the hole I added for access to the iVault lock.
So, it was time to do a little cutting. I've got everything marked out and ready for the Dremel.
After the cuts...
Let's clamp that piece in place...
I cut a piece of plexi to fit behind the hole, and epoxied it in place. Once the epoxy cures, it will get smoothed out with a fiberglass reinforced Bondo.
After a few light layers of Bondo and subsequent sanding, I gave it a quick shot of primer. Here you can see the fresh primer still in the process of drying. A few more coats and it will be like glass. I dare you to say it doesn't look completely OEM.
The last thing I did was reassemble everything to triple check fitment. It all looks good, so it's on to mounting the EQ solidly, and getting a fill plate made for the HVAC. Then it's painting and final assembly!
Well, after not doing much for a week, I tried to be productive last night. I swapped cases on my Nook Color to something more appropriate for the Jeep. I still need to get some hardwiring done, and also build custom touch contacts for docking. I'm just waiting on some parts from Mouser.com.
When I last left off, I was waiting for a few parts to arrive. Once they did, I set out to make the Nook easily docked in the Jeep. A lot of the more expensive tablets, such as the Samsung Galaxy Tab, make docking a breeze. Of course you have to spend nearly twice as much on the tablet to do so. That would defeat the purpose of doing this mod in the first place. Affordable and durable are 2 very important criteria here, and I've got to stick to the concept.
So, let's address the power issues first. The Nook needs to be able to be charged once it's in the cradle, and there's no way I was willing to plug/unplug in a power cord every time I wanted to take it in or out. The tablet is supposed to simplify things while bringing more features. If I can't accomplish that, then I was better off leaving a regular head unit in place. I wanted to just grab it and go.
Getting power to the Nook started with one of these. It's a micro USB plug with a board and solder points. You can see a test fit with the Nook in the cradle.
Next I had to mark out a small area that needed notching. This would allow the USB plug to seat fully in the Nook.
After the notching...
Okay, so now it was time to figure out a way to mount the plug to the cradle. I needed something simple, strong, and clean. I decided to bend some plexi and cut it to size.
Now that I had a mounting system in place, it was time to wire the plug. The method you see below allows for a USB extension cable to be added easily to the cradle.
In the next update I'll finish the power dock, and move on to a revised dash mount (I'm never satisfied!)
I've got a sneak peek at the almost finished install here. The biggest addition is stainless steel bar that now sits in front of the EQ. This bar will help protect it from bouncing and stray objects or people. The bar also serves a secondary purpose. It does a pretty good job of hiding the EQ from anyone peering in the windows when the top is on. Although I didn't get pics of the process, the bar is fastened to aluminum plates that are epoxied behind the bezel. It's pretty strong, and certainly isn't going anywhere.
It may be subtle, but you might also notice the tablet and mount are now sitting closer to the dash than in previous pics. I redesigned the mount and made it more secure while giving it a cleaner look.
With most of the work done, I'm now going to focus on a few smaller details. I'll cover that and finish this update in an upcoming post.
Touch contacts... I've mentioned them several times in the past, and now I've finally got a few pics to show you what I'm talking about. First though, my reasoning for implementing them. For it's price, the Nook Color is a brilliant piece of hardware. It's solidly built, and has a better screen than most tablets over twice it's price. The cheaper cost makes for a few missing features compared to other tablets, but when you consider this is marketed as an e-reader, it's pretty understandable. I've mentioned how I couldn't justify spending more on an Android tablet that would see some potential abuse. So, I had to get creative to overcome what the Nook was missing, particularly a docking port of some kind. If you've got to plug and unplug cables into the tablet each time you get in and out, it becomes a huge pain. You've already seen me fab a micro-usb connecter into a tablet dock. Now it was time to move on to the audio.
I've used these touch contacts from Mouser.com on other computer modding projects, and knew they would be perfect for what I'm trying to do here.
One of the most important aspects of this mod, was that I wouldn't have to change anything on the Nook itself. I wanted to leave it structurally intact. Should anything happen to the Nook, and I need to get it replaced, I won't have to redo any of my work. It also means I could sell it if I want, and not affect it's value in anyway. The Trident case I chose for the Nook is a critical part of this mod, and was bought specifically with this in mind.
Here I've found a flat, open area, and marked it for cutting.
A little time with the Dremel and a file left me with a perfect fit...
Up next, was a custom cable made from an angled 3.5mm plug and length of USB wire. (I only needed 3 conductor wire, but chose to use this due to it's increased thickness.)
Although I didn't take a picture of it, to fit the cable in the case, I drilled a small hole in one end, and used the Dremel to create a very shallow channel behind the case to route the wires to the touch contact. I soldered the wires to the contact, and put the case on the Nook.
As you can see above, the fit is excellent, and the function is even better. The case is removable without harming the Nook, and I've not compromised functionality in anyway. When the tablet is out of the Jeep, the contacts are unobtrusive, and should I need to use headphones, I can simply unplug without affecting anything.
Up next, the dock will get some contacts of it's own...
As promised, the dock now has contacts. It couldn't have been simpler. I cut a rectangle to fit the touch contacts, epoxied it in place from the back, and soldered on a 3.5mm plug. The dock was reinstalled in the dash, and I was done!
So, what now? We'll I plan on taking some video of how easy it is to dock, and some of the tablet's basic features. That should give you some idea of how well things really work together, and why I really love this setup.
Looks like a solid install. Awesome work!

Thanks! It is very solid, and a great solution overall for a vehicle like the Wrangler. Any other vehicle and I would have integrated it into the dash itself. It didn't make sense to do that here, but I wanted to make sure it was more custom than 'just throwing a dock on the dash.'
holy cow.....very nice!
Very well done. I especially like the contacts for the audio. nice touch.
Nice to see you over this side as well. Love the work. I'm thinking about doing it more and more I see it.

Nice looking install! Interesting too as I've been considering something similar in one of my cars.
is the USB going to be for charging only, or are you planning on adding a USB GPS unit? (assuming nook will do host USB)
If the USB is going to be for charging only you can improve the charging rate by shorting the two data pins (the inner ones) - the millom will then show"AC" when it shows "charging" on the status panel, and will draw more than 500mA which is what it limits itself to from a normal USB port. Its not as fast as the stock wall charger but still an improvement.

The Nook is set up to use host mode. I've got the cable and adapters, but haven't installed them yet. I planned ahead so it's a simple plug and play from cables I can reach through my glove box. I am experimenting with a SSD based hot swap usb device. It 'usually' works, but I'm going to do some more testing before I go ahead with it. I've got around 40gb of music I'd like accessible at all times if I'm going to do it right.
I know that it's a little slow to charge this way, but it's never been an issue. The power to the Nook is a 12v constant tapped into the OEM stereo harness. I do have a shut off switch if I don't drive the Jeep for extended periods, but otherwise it's always on. The power draw is so minimal that I'm not in the least concerned about battery drainage. If it did happen, then I'd want to replace the battery anyway, as it has no business in my Jeep.
I don't use a USB based GPS device, I use a bluetooth one instead. It's mounted above the driver side visor, and powered via a USB cable ran through the windshield frame. It only charges while driving though. It's attached with velcro should I need to easily remove it. Here is a pic.

12v? Does that work ok? I experimentally modified a USB charger as test of the AC-charging thing, but hard wiring to switched 12v would be easier.
After my post I searched here on XDA and came across the BT adapters - much easier than USB, plus I can wire in a decent GPS antenna inside the dash. What model is your GPS unit and does the BT have the range to pair reliably? I've seen a few posts saying it only works a few inches
Thanks for the info and posting the install !

I should clarify. I'm using one of these wired to constant 12v. The Nook is receiving a standard 5 volts from a USB cable.
I'm using this adapter, and it's been flawless. It picks up the GPS signal quickly, and pairing takes only a second. It's kept it's pairing at a distance of about 5 feet during testing, but as it sits in the Jeep, it's only about 2 feet away. I've never had it lose connection.
What nav software do you use? I'm wondering if the bluetooth GPS works with Co-Piolt or Navigon? I do not want to use google because i'm on a 200mb data plan.

Hey all! So as a bit of a computer/tablet/phone geek and and a bit of an RC Hobbyist, Ive decided to take on a little personal project to combine the two. At least a little bit to start. In the world of RC quadcopters (aka drones) the big thing that everyone is into is buying these expensive 1080P/4k go pros and other gimbal devices to record video. But not only do we want to record, we want to be able to view a live stream of what the drone sees. You can buy these FPV Cameras on the higher end for $500+.
When I bought ny first drone a fair sized flyer at nearly 2ft diameter, my first flight I decided to strap my old Galaxy S3 to the bottom and catch some cool video. Everything went well, and the video was high def and crystal clear. While there are FPV apps such as AirBoss available, unfortunately its a bit glitchy and crashes often so i didnt bother with FPV, just hit record and flew. After this I decided to start looking into purchasing a gimbal and maybe a gopro hero 3. Seems a bit silly buying a $400 camera to carry on a $100 drone, but I considered it and started browsing.
Before buying anything, I had a buddy want to see the drone fly, so on a semi full charge, I took it up, no phone attached, and after about a minute of flight, the battery went low, lost contact with the controller and helplessly watched it drift into the woods, still haven't found it.
So now instead of looking for an expensive camera, im looking to strip down my old s3 and use it as a camera, but also as a GPS locator, which will have data/gsm/gprs connections. The idea being, that not only a does screen less, make shift house, remotely controlled android device act as a camera, but it can be called from another phone (making it easy to track via sound) or worst case scenario be pin pointed on Google maps, in the event of another downed drone.
I have all the apps installed to make this work exactly how I need it to and want it to. In fact I already have the motherboard stripped out of the housing, and am able to do exactly what I want, except one thing.
The only way the phone will turn on, is with the main components from the screen housing plugged in. Its one ribbon, but its the ribbon the feeds the Screen, the digitizer the home, back and menu buttons and the micro phone and the vibrator pod. All of the components on the back side of the board, the front and rear facing cameras, the sim/tf card readers, the loud speaker, led, volume rocker etc can be disconected, as long as the main ribbon for the screen is attached, the motherboard will boot. After booting I can unplug the ribbon, and the phone will remain on, with everything working that I need to work, including remote access.
I guess the main question here is, how can I trick the phone into thinking the main ribbon is attached? Once I can get it to boot up without it being attached to that ribbon I can begin building a lightweight housing for the board and camer and a smaller battery. I thought about cutting the ribbon and just leaving it attached to the board, my only problem with that is IF it wont boot after doing that, I cant just repair the ribbon and I dont have a spare s3 for parts, which would pretty much leave me with nothing but a dead s3 in pieces lol.
I know most of what xda deals with is software development, but im hoping someone has tinkered with hard ware before. Sorry for the novel, just wanted to cover the details and eliminate getting asked why I want to do this. And for the record I want the s3 screen and housing gone for the simple fact that I can cut the weight from abouy 150 grams to less than 30 grams, which is a huge factor when flying quad copters
