I spent several hours over the weekend rooting, unrooting, and re-rooting my new NST. Each time I rooted it, I ended up with a touchscreen problem where touches registered with the wrong column.
For example: when trying to use the backspace key, 'h' would also register. When trying to use 'p', 'e', or 'r', 'y' would also register. Both the key that I wanted and the central key would indicate a keypress (turn black) but only one of them would register in the text box. This is entirely dependent on software, but it's something that is cleared with the 8x failed boot restore and not with the two bottom buttons restore.
I have tried both TouchNooter and MinimalTouch twice. My latest attempt was MinimalTouch:
Start with a clean NST with software 1.0.1
Install 1.1 update (keyboard still works)
Follow MinimalTouch procedure
NST is rooted and android home screen is accessible, however, the keyboard no longer functions properly
Perform reset (hold bottom two buttons on startup)
Button Saver is gone, android home screen is not accessible, keyboard still does not function properly
Perform 8x reboot restore
Keyboard functions perfectly
Has anyone dealt with this before? I couldn't find anything with the search function.
Though this thread appears to be doing nothing, I will at least let you guys know of the current idea:
I have gone back and checked the touchscreen after each step in the procedure, and appears like the 1.1.2 update causes the problem.
Without any rooting or funky installs:
Perform 8-reboot reset
Touchscreen works fine, SW 1.0.1
Install 1.1.2
Touchscreen is impaired, SW 1.1.2
Perform 8-reboot reset
Touchscreen works fine, SW 1.0.1
Did the 1.1 update include a change in the touchscreen sensitivity?
How do I ensure that the IR sensors are clean? A shot of compressed air?
Should I just call B&N/sears and try to get a replacement that functions properly with the update?
I believe that I have determined the cause of my touchscreen difficulty:
The front bezel of my NST is not entirely glued down. I noticed that the spacing was irregular between the eink display, the black (really dark) plastic layer, and the top matte gray layer.
Squeezing my NST temporarily blocks the issue (until the glue re-expands)
The software updates must change the touchscreen sensitivity to some extent, causing the poor tolerance in my particular NST to result in inaccurate touchscreen response.
I'll be talking to the manufacturer or the seller (Sears) soon about a replacement unit.
I hope noone else has to figure their way through this with a brand new nook!
Sorry for resurrecting a death thread. But my nook simple touch (which was rooted and had button saviour etc), slowly started having problems with touch. Now since 2 days, touch screen isn't working anymore, no matter how much cleaning I do to the bezels. I can't even open it due to the slider lock screen. Don't know what to do. I would be happy to settle with a button-based navigation, all I want to do is to read epubs. Any help greatly appreciated. I can prob for problems. I have a rooted nst1 which I haven't tinkered since 2012.
If this isn't the right place, I will start a new thread.
TIA

Have you tried swiping two fingers across the screen from right to left? This is not my original idea but someone else long ago delivered me from your situation with this simple tip. If I ever knew the explanation, I have forgotten it. Probably something with the multi-touch kernal. It will even work on an unresponsive lock screen. I still use it on occasion, so something triggers the behavior, but it is generally infrequent.
If that doesn't work to restore functionality then something more dire has happened.

Your swipe lockscreen may present a problem.
I don't see any entry in the settings on my NST, so I don't know how to disable it.
You can download my Touch-1.0.apk from the signature.
That will help you debug the tricky IR paths.
All the lines should be light gray, darker lines indicate an occlusion.
The corners are always difficult and you may have a line or two dark.
The problems are either dirt on the bezel or the bezel/filter/display coming unglued.
You can install and run it (without a launcher or touch screen):
Code:
C:\>adb install Touch-1.0.apk
C:\>adb shell am start -n com.temblast.touch/.Touch
I am sure that my nook is rooted , but adb isn’t working. May be usb debugging isn’t on. The problem is that I can’t even unlock it past the “drag to unlock” screen. Now I have to find out how to enable adb without having a working touchscreen to install the touch1.apk.
The two finger swipe isn’t working. I used to draw a single finger across the borders clockwise, which used to help calibrate the touch , not working anymore.

Well, you should be able to tell.
There are three ways to interact with a running Nook:
Touch screen
ADB over USB or WiFi
Hardware root console
You seem to say that the first two don't work.
You can also try a factory reset or recovery.
There is the whole OmapLink thread that describes how to unbrick an NST.
Here is the middle of the thread, you might need to read before and after:
https://forum.xda-developers.com/nook-touch/general/root-nook-glowlight-t2853056/page6
I did a factory reset and the nook is at startup screen with the NEXT button, which obviously can’t be pressed. So the touch issue is definitely “hardware-related “. Few days back I travelled to a hot and humid place , carrying my nook and the soft rubber part in the front of the bezel, started coming of. No matter how much I clean the bezel , this time touch isn’t coming back. I am wondering whether there’s any way to disassemble and readjust the ir sensor for touch.

It's stuck together with the standard super-double-stick tape.
It's hypersensitive to the slightest bending up or down of any of the layers.
Without ADB and diagnostics (like Touch-1.0.apk) it's impossible to figure out which bit of the edge is out of whack.
It sounds like you only have two options:
Get the hardware console working with a 1.8V level shifter and a UART.
(Easy for me, may not be easy for you.)
Use OmapLink to boot an image that has ADB running (like Noogie or CWMR)
and enable ADB on your main image.
I remember rooting it in 2012 with some image burned on my SD card. Is there a way to again root with the help of an SD card without involving touching the screen with adb enabled rom. That way I can install the diagnostic app and dismantle it to prob further.
Sorry, it's been so long that I forget all this stuff.
Yeah, if you put Noogie on an SD card, I believe that it will boot from there.
With the OmapLink and Windows 10 it can be a bear sometimes to get the three (all the same) drivers working.
Windows 10 is really crappy on recognizing/capturing USB devices that appear briefly.
I can't get W10 to see 0451/d00e
My Raspberry Pi grabs it immediately:
Code:
[ 60.061477] usb 1-1.3: new high-speed USB device number 4 using dwc_otg
[ 60.202744] usb 1-1.3: New USB device found, idVendor=0451, idProduct=d00e
[ 60.202756] usb 1-1.3: New USB device strings: Mfr=33, Product=37, SerialNumber=0
[ 60.202766] usb 1-1.3: Product: OMAP3630
[ 60.202774] usb 1-1.3: Manufacturer: Texas Instruments
[ 63.348937] usb 1-1.3: USB disconnect, device number 4
It appears for 3 seconds from a cold power up, that's too quick for W10 to do anything.
I saw a video on YouTube on screen replacement, with complete disassembly and assembly. Opened the nst , took out the screen from the bezel (keeping the screen and the aluminium metal frame intact, too much sticky tape there), wiped everything clean, reassembled everything back. Still the same problem. I am wondering, even if I somehow get to install and run the diagnostic app, what kind of hardware alterations we need to do. Since the infrared touch LEDs are on the back of the motherboard, what kind of alignment would be necessary.
Is it to the metal frame or the plastic bezel, do we need to tinker?
Did you use new tape?
I think that everything has to be really tight and old tape seems to leave gaps.
There is also the possibility that the MSP340 has lost its mind.
I'll have to look at my oldest NST.
I haven't detached the screen from the metal frame. But the screen attachment to the front bezel seems to be attached to a plastic ribbon which was partially coming out of the front frame. It was sticky so I reattached the screen/metal frame back to it the front plastic part. Now when I see the screen up front, the bezel space/gap between the screen and the black plastic part is uneven. I don't thing that can be repaired as the front black part is disintegrating. Three of my four page turn buttons are no more attached to the frame, I have kept them there with tape.
Well, I completely cleaned with Goo-Be-Gone and isopropyl alcohol the bezel, the filter and the display.
I redid everything with 4mm Tesa film: https://www.microcenter.com/product/507366/tesa-double-sided-tape-4-mm-wide
The horizontal spans (except for the corners) are good, the vertical spans are still problematical.
You can lightly press and warp the bezel and things go in and out.
I think that I'm throwing in the towel on this one.
Reasons to dump the NST: Android 2.1, 256M RAM, OMAP3621 not being further developed by B&N
Reasons to keep the NST: Only Nook with a bare eInk (no backlight layer, no capacitive layer)
Don’t know about the filter, but the bezel looks very fragile to handle. I also believe that the time has come to retire it. But what I liked the most about nst was it’s screen and ability to side load books via wifi. I had gmail and opera mini installed on it. All I needed was to send a link to gmail to download the book, after the Dropbox support was gone. I am searching for a similar ebook reader. Can’t decide between Kindle paper white(which is available locally) and nook glow light 3(which has to be imported). Any suggestions welcome.
Well, the "filter" or "lens" or "light pipe" is what I'm calling the flimsy green translucent piece.
I've never even looked at the Kindles. I don't want to get involved with that whole ecosystem.
The Glow3 is physically almost the same as the NST.
I've got enough devices with browsers on them.
I use my Nooks with WiFi off and sync with USB (ADB & AdbSync).

Hi,
On my rooted nook touch, sometimes the touch screen stop working.
It appends whatever software i'm using and randomly. Buttons works, page refresh works too and the nook doesn't lag, it's just a touch screen crash...
I tryed to unregister the nook and to update it from 1.0.0 to 1.0.1 then root it again but the problem still here.
Do you know a solution for this problem ? each time it's append I must hard reset the device (power + right bottom buttons)... is there a service to restart to enable touch screen again ?
Thanks
Hi, I'm new here ^^.
I bought the nook touch 2 months ago, and it worked perfectly until yesterday. I installed MSN Mercury from the market, I logged on my account, but when I clicked the menu button, the touch screen stopped working and I used adb reboot from my pc to restart it (I didn't know how to hard reset).
It scared me a lot, and I uninstalled that msn when I restarted the nook.
I request a solution for this too, and, do you know a simple MSN that works perfectly on our e-Ink nook?.
PD: Sorry for my bad english ^^u
Same as you.
Just screen is out of response.
Happened both 1.0.0 1.0.1.

Long thread about the subject.
From the thread and running into the issues myself, it seemed to be a sensor/dust issue as the only solution I found working is wiping the screen with a cloth or so. This is kind of sad since I already has a screen protector on it but I guess any bit of dust on the screen could cause the touch function to fail.

I do not have much faith in the dust theory, you'd need some serious dust, like sand, on your screen for the sensor array to even notice it
Remember, it's not a touch sensitive screen like those on phones and pads, but a rather coarse infrared grid "above" your screen.
I've experienced this once myself, and then I simply put the NST away for the night and when I woke up in the morning it was working again which makes me suspect a lockup in the driver,
Had this happen to me. Here is the timeline
1. Girlfriend bought nook for birthday
2. Dropped said nook after 2 months or so
3. Bought refurb off ebay from B&N's ebay account
4. Screen would stop working randomly
5. Contacted support
6. They shipped me a refurb replacement
My second nook wasn't under the extended warranty or even a 30 day warranty. Its a manufacturing issue so they should replace it for free.
Ok, so I had this same problem, and took it to B&N, they said that they hadn't seen that before a gladly replaced it for me. To this day I'm still not sure what caused it, but I know it happened after leaving it in a pretty how car, but not sure if that's linked or not. My current one which I've had for about 5 months hasn't had any problems.
Old thread is Old but I'd gotten mine knocked out of my hands. Screen looks undamaged but the hardware buttons don't appear to do nything other than holding down the n switch to make the glowlight come up. Tried putting it to sleep, plugging it into a computer. Only thing that seems to indicate it isn't a total brick is the glow will come up. Other than that screen has a static of the last book I was reading in coolreader.
Bought the thing for an easter preasent to myself from walmart. Still have the box but it's rooted and til the drop had no problems whatsoever (well problems that weren't due to user error.) Saw a 'leave it overnight' suggestion and am going to ttry that.
Is there anything I can try or is this going to be one of those 'the outside looks fine but the slight bump wiggled something loose that you're going to need to tear the whole thing apart to fix.' things?
Edit: failing that could someone walk me through the button presses/times to press each button to un-root/restore backup using NookManager? I'd be doing that blind as the screen only shows an image from coolreader but I figure better to try taking it back to stock before returning even if nobody looks it over.
Hi All,
Solution for screen as simple as... get tissue, dump it with a bit of water (tap water will do) and clean your screen carefully. Solved Make sure that water gets into corners of screen. There is some kind of filter. It must have connection with top of the screen... some how water do the trick. I was designing custom cover/case for my nook when I discovered it. BTW your finger shod be a bit wet when you use your nook.
Hope it helps!
Thanks

The Nook doesn't have a capacitative or resistive touch screen, so having a wet finger is irrelevant. Instead, it uses an infra-red touch screen. Between the screen and the grey plastic bezel, you'll see a transparent lens protecting the IR emitters and receivers used to determine finger position. Reportedly, if that gets dirty, it fails to register finger positions.
eBay seems to have a bunch of items for the digitizer, like this:
http://www.ebay.com/itm/Touch-Digit...781?pt=LH_DefaultDomain_0&hash=item35bf960985
But do I need this instead?
http://www.ebay.com/itm/Full-LCD-Di...805?pt=LH_DefaultDomain_0&hash=item2c680306ad
Touch screen still works, I'm assuming the digitizer auction (first one) is all I need.
Anyone ever done this before? Seems relatively straightforward, but a long process.
Edit: Also, my touch screen has been acting up as of late, with touches being randomly registered when I'm not touching it.. mostly the bottom portion of the screen would get touch inputs at random.. very annoying when typing and browsing/scrolling.
What part would I need to replace to potentially fix this? Might as well kill two birds with one stone.
Hi, I'm not too sure about the question, but I'd recommend taking screenshots of the eBay page and posting them here instead of the links as eBay Links aren't allowed here.
Hope everything works out okay though
I had to replace my digitizer... It wasn't very hard as long as you have the tools and you follow the instructions you should be fine...
The ribbon cables look difficult to plug in. Any advice? I guess the obvious thing is to just line them up properly and push down (with the tool, finger?). I've built computers for decades, but have trouble with those tiny things.
Thats what I did just lined it up and pressed it with my finger
Hi, I cracked my outer screen on my A500 and just got a replacement. The tablet worked fine though. The touch screen still allowed selection of anything on the entire screen even though it had lots of cracks on it. The LCD screen wasn't damaged at all.
Followed the videos to replace the screen that are posted to the letter, slowly and methodically. So I separated the outer screen from the display OK (it was a bit of a challenge since the double sided tape was holding pretty good).
Everything went together OK. I go to start it and the screen glows as it normally does as the very first part of the power-on. But nothing else. No logo, no messages - nothing.
But I plugged it into my PC via micro USB on a whim and lo and behold, I can actually see the internal storage and SD card. Looks like everything is there. And if I do the long press where I recall some of the icons are, I can feel the slight vibration as it selects the icon. So it would also appear that the touch screen is functioning too.
So it looks like the unit boots but for some reason, won't display. The screen just glows faintly like the very first part of a power-on.
Is there hope? Is there something I can do or check? Is there a way to verify the LCD without buying a new one?
Thanks,
Bob

Well Bob, glad to see some folks take matters into their own hands!
I can't find the post, as it was a couple years or so ago. But I specifically remember a similar situation. And from what I know, when you tighten/place the screens together, you have to make sure you tighten them evenly, or else nothing works. Something to that effect. Also, I would probably take it apart again, and double check that everything is connected the proper way. Look for possible bent pins and such.
As far as I know, there are no software maintenance apps to check the lcd. Not to my knowledge anyhow, As we pretty much have all maintenance software for the 500/501.
Wish I could be of more help. I know awhile back, a couple of folks here in the forum replaced theirs after their kids stepped on them.
Hi,
I have recently bough a Nook Simple Touch with Glowlight (BNRV350). Used, no guarantee. It looks fine (has only a minor scratch on the light dispersing layer). Problem is - the lower half of the touch sensors give misplaced readings. For example - during the registration process I cannot get through the language selection screen. I can correctly mark English, but when I want to press an arrow to go further, Nook changes my mark to French, instead of getting me to the next screen. Cleaning borders of the screen with microfiber cloth and cotton swabs did not help.
I have another NSTG working fine, so:
1. I tried to copy its stock system backup and loading it to malfunctioning one. It didn't help. I could not even unlock the screen (although I could press "power off" or "cancel" buttons after holding power button).
2. I tried swapping mainboards (IR sensors are on them, not in the screen assembly). And It turned out, that wherever mainboard of the faulty unit is, the touch does not work properly. I tried to blow out the dust from those misbehaving sensors hoping that it just somehow got on the motherboard, but it did not help either.
So the question is: What else can I do to make those IR sensors work properly?
Thanks in advance for looking into the problem!
(Sorry for my English, I'm used to reading, not to expressing my thoughts with it.)
Maybe try to look on the sensors with a cellphone camera in dark room-then probably you will see which of the ir leds aren't working (if the problem is in leds not the sensors)
Sent from my Lenovo P780 using Tapatalk
Unfortunately I couldn't find any camera able (tried mobile phone, point'n'shoot, DSLR...) to detect IR in their stock configuration (and messing up with disassembling the sensor filters seemed as not worth the case). I ended up buying another NSTG with shattered eink screen and salvaging its properly working mainboard (+completely fine battery, all for about $7). Problem solved. Kind of.
If you are having problems with the touch screen try using the app posted here:

It may give you insight into where the problem is.
It will help us get an idea of where problems are occurring.
Thank You. I've read about Your program, but since I could not even unlock the screen or get past registration wizard (when trying to get that unit to factory state) I was unable to use it.
The Menu button (when you mapped) gets past the swipe.
You can start stuff with ADB intents.
[Q] [possible bug] Nook Simple Touch touchscreen input "barring" horizontally
So I just rooted a Nook Simple Touch that was running the 1.2.1 firmware. It's pretty nice to have web and other apps on it. However, a few seconds after turning it on, when I touch the touchscreen to type or really to press anything, the Nook seems to interpret the touch across a horizontal bar of screen simultaneously, and exclusively activates icons as far to the right of the input touch as possible. e.g. if I press the e key on the soft keyboard it activates the p key. If I press the back button at the top of the screen it opens the WiFi dialogue, and if I hit the nook hard key at the bottom and press the home icon in the menu at the bottom of the screen, it opens the settings dialogue.
Has anyone else had this problem? Any fixes? I used NookManager 0.5.0 and the AppsAttack 0.5.0 on a 4 gig micro SD card to root it. I'm pretty sure it's a software issue as it does not happen during the first few seconds of operation. I was able to type half of an email in Gmail with no problem before this started happening. I've turned the NST off and on several times but the problem keeps occurring.
1. Clean all the edges of the screen with a soft cloth and remove any dust particles. If that does not help, then:
2. Try to restore your system to unrooted state from the backup that you made, before rooting. (You have made one, haven't you?) If that does not help, then:
3. Read about Renate NST diagnostic application:

http://forum.xda-developers.com/showpost.php?p=52674827&postcount=8
If that does not help either, then:
4. You can probably buy another unit with cracked display for dirt cheap and switch the motherboards. The only tools you'd need for that will be a torx screwdriver, size 5 and something like a plastic toothpick to pull out the power on switch. Disassembly instructions are on the youtube and other ifixit for example.

Thanks. There is a dusty screen protector on the nook. (the stick-on kind) which I could try removing. However like I said sometimes it senses touch just fine... the "bug" doesn't kick in until I've been using it for several seconds. I do have a backup... will Nook Manager handle restoring that? I formatted my Nook Manager card after I used it to root the nook. Will it still work if I put nook manager back on it.? Thanks for the good reply.

If it's a NookManager backup, NookManager will restore it. And yes, it will work if you put NookManager back on the card.
