Post here about anything you might have found out about the internal NookColor hardware.
Here's one to start with:
Look at dmesg under Android. The wireless driver is TIWLAN, and a little Googling correlates the line "Chip ID is 0x4030111" with a WL1271, a TI part with 802.11b/g/n, bluetooth, and FM. However, as far as I can tell Bluetooth isn't anywhere to be seen in the Nook ROM.
This document shows the typical setup for the WL1271, which is for WiFi to connect to the host through SDIO (one of the SD/SDIO/MMC interfaces) and Bluetooth and FM to go through a UART.
There may not be antennae for BT and FM, but we should definitely look into this

Maybe not FM, but that document I linked shows a "WiLink 6.0 Solution" that uses an antenna switch so only one 2.4GHz antenna is needed for BT and WiFi.
Ohhhh, this has some interesting potential!
I got Flash 10.1 to install, but cannot get the B&N Browser to Dolphin to recognize that its installed when I try to do something with Flash (tells me I need to install it)

Interesting, but let's keep this thread on the topic of hardware.
Have you tried checking the ttys? Or even just trying to put a bluez stack + firmware taken from another device on it?
BlueTooth
Please, Oh Please, tell me that this device can do BlueTooth. The ability to add a wireless keyboard would make this device Perfect for me!!!!
Agreed, Bluetooth FTW. We could be one kernal injection away from BT!

I didn't bother; from that doc I posted there's a GPIO enable for bluetooth, and unless the BN developers were complete bozos they've turned it off and left it off in this kernel. We could go searching for it, but it would get tedious. I am willing to bet that it's referenced in the BN u-boot and kernel sources though.
The TI WLAN/BT/FM driver and firmware can be found here: http://gforge.ti.com/gf/project/wilink_drivers/
This might not be the right section. But what are the possibilities of overclocking to possibly run the tablet version of android "3.0" which is said to require 1ghz or faster processor??
This is an interesting find. My guess is that it would have been too much of a hassle for BN to get a WIFI only chip so they opted for the ready made one and disabled the rest of the functionality.
But I think until we have a cooked ROM for the Nook we won't be able to see BT any time soon. This is too stripped down an OS.

It's clear that the NC is based on TI's ebook reference platform. Given the amount of TI silicon in there I wouldn't be surprised if TI cut them a deal on this WiFi module such that it was cheaper than another company's WiFi-only one. It's not clear what's inside the module, and for all we know there is no BT/WiFi switch, which would make it impossible to run anything but WiFi.
As long as the module has a switch, it wouldn't make any sense for BN to hard-disable the bluetooth. There aren't that many connections just to get BT data, and I'm pretty sure the OMAP doesn't use those connections (1 GPIO, 1 UART) for anything. It would only cost a few PCB traces and maybe a pullup resistor or two, less than a couple of cents at scale.
The nook is getting 3.0 Already confirmed.

It seems pretty unlikely, to be honest. The NC wasn't intended to run straight Android so can't see B&N being massively interested in supporting future Android versions.

That's a fairy tale. The next version of android will be 2.3, and nothing about 3.0 could be confirmed as it's likely 6 months away at least. And no one has really even confirmed anything about 2.3. It's all been sightings and rumors.
But back on topic - has anyone had a look at the TI Ebook reference material? Maybe they have a vanilla version of android that is made to work with the processor? It's possible the Nook hardware is similar or identical to some TI reference design - it is the first product based on that chip after all, maybe B&N just let TI design the thing?
EDIT: At the bottom of the page for this processor it says: "This product is intended for high-volume wireless OEMs and ODMs and is not available through distributors. If your company meets this description, please contact your TI sales office."
So Grr, looks like they're not going to share much unless you're a big company. Sometimes these guys have lots of support material for their processors, but I guess this one is too specialized.

I browsed through a bit. Looks like very well supported hardware - the driver for the WIFI chip is in the AOSP source tree, and the graphics chips is pretty common.
It would seem to me that a port of Cyanogen would be very straightforward. The missing buttons would need to be mapped to something - maybe an additional UI component which popped up for menu and back? - but other than that...doesn't look too bad. Simpler than a lot of others, maybe.
And damn, this device looks like it would be pretty quick. It's no slouch now, and with Froyo...and maybe a touch of overclocking... it would be faster than a Nexus one with absolutely killer battery life.
A very commonly available, high-quality Cyanogen tablet for $250?
Sick.
You could copy the Archos on-screen buttons (which look really annoying but are better than nothing)

Eh, as far as I can tell it's the same die as the 3630 but in a lower pin count package, without a package-on-package (DRAM/flash stacked on top) version, no camera interface, and only specced for 800MHz. The 3630 comes in 1200MHz versions, and as we've seen with the Nooter bootloader (by accident) it's possible to make this part run at least at 1GHz.
The datasheet for this part is the general 36xx series datasheet, and at 24MB isn't lacking at all (except for the DRM stuff).

You could.
There's a thread in the general section right now about a button remapping app.
I just manually did what the app does, pulled the .kl files, changed VOLUME_UP to BACK and VOLUME_DOWN to MENU, pushed the files back and rebooted.
Et Voila, Bob's yer uncle, I now have menu and back keys...at the expense of losing a couple of volume control keys about which I care not at all.
Nice.
Hi Guys,
First post here so I could'nt post in the relevent thread. It has been noticed that there is a switch on the Tablet S PCB that apparently disconnects the battery, I've opened up many devices over the years and have never seen that before - very strange if you ask me. Might be of interest to some to note that the Sony PSP used an anti hacking method that utilised the battery !!, so we may be on to something here.
On PSP a hacked battery is called "pandora battery". It is not a switch. The battery has four contacts. Two of them are the voltage contacts plus and minus and two of them send a serial signal code. With the right code, the PSP boot in a special (hidden) recovery menu. Do you have more information about the tablet battery and the switch? Pictures available?
Wouldn't the relevant thread be the ones you found out about on it?
original discovery of switch here (with pictures)
Then I brought it up in the dev thread about APX mode here
And yes it exists... can confirm it's there (at least on my 16gb model anyway)
My thoughts are is that there would be a factory cable used here (similar to the motorola factory cable) and they need to disconnect the battery for it to function as it should.
And a hunch that it could very well have something to do with APX mode, however... since people have stumbled into APX mode completely by accident with no hardware commands, that kind of contradicts that thought.
I don't have any info on the battery or the switch, I was just pointing out the strangeness of having a switch to disconnect the battery, nothing else I have ever looked at has this feature. (and I've opened up a lot of devices)
It just makes me think that there is a need to easily and repeatedly disconnect the battery during the manufacturing / assembly / repair process.
For example, does the system "know" when the battery has been disconnected and allow different operations ? - fastboot perhaps ?
I know this is all supposition and it may mean nothing at all - but the feature is bugging me - it cost money to implement and I can't help but feel it's there for a reason.
System woiuld'nt let me reply in thread I was reading - said dev section was for expert users only ??

I thought of this too but then went on to think that there's probably no way such a thing would transfer accross do android/unix codes like that. ie they use android kernels and stuff, they don't make the whole thing themselves. Plus they realised the vulnerability of it and removed it in models like the psp 3000 and go (not sure about 2000).

Early PSP-2000 models still had the vulnerability.

You're actually pretty close, I think. Android would be perfectly capable of receiving certain boot codes, but these are far more likely to be wired to the more capable micro-USB port as in just about every other Android device. While an Android kernel could theoretically receive serial codes from almost anywhere given the right instructions, Sony would probably not do this. As mentioned, the PSP's ability in this regard caused many problems.
As mentioned by the others, if someone could post some good hi-res shots of the battery and surrounding PCB or something like that, that would make it much easier.
Sony's philosophy has always been that the end user should use the product as it was built and the purpose it was built for.
They've always made hacking and rooting very difficult for users. They don't like their products being tampered with.
I can understand where they are coming from, but at the end of the day, with many phones and tablets, if root techniques and mods aren't available, many users won't buy the goods.
All PSP models, including the 3000 series, excluding the go have been cracked.

pandora battery worked for psp 1000 and psp 2000 before the TA-088 V3 motherboard, all the next models where hacked by firmware homebrew enabler, but not by battery mod..

Just to clear things up, what works on the PSP will not, generally speaking, work on the Tablet S. They are different hardware, with different interfaces to different firmware which runs completely different software.
If we can get a look at the PCB in closer detail where the battery connects we might be able to see if there are any serial pins, but I doubt there will be. No other Sony product since has featured it (to my knowledge).
Hello there,
I'm facing some troubles using my GPS (i9100P). I think it's a hardware issue since I already tested different kernels / ROM and tried multiple GPS tools without big changes. I just successfully improved the quickness of the fix.
For now, fix is just awesome : 10 satellites fixed in 3-4s. The issue is related to the weakness of the signal. It can be lost when driving near a truck, a bridge or small buildings. Using "GPS test" software outdoor in a clear view, SNR is about 25-30 for the best satellites. I think it's weak !
Do you think it's a hardware issue (probably my GPS module ending its life) ? Which part should I change ? I think it's the module including speaker but I'm not sure :

Hope someone can help me to fix that issue ! Thanks

I don't have service center near home / work :-s.
If my S2 needs to be repaired, I will probably do it myself. That's why I need to know what part to change. Since phone's value is near 100€, I don't want to repair it if that costs more than 20-30€.
Anyone knows which part of the phone integrate GPS module ?
You need the service manuals; they've been posted here from time to time - do an XDA search (or a Google search with XDA appended to your search terms), or a Google search should find them easily enough on other sites.
You could also take it to any local mobile repair shop, it doesn't have to be a Samsung service centre who does the repair.
Got it ! Thanks
I learned that speaker part integrates antenna, and GPS receiver is fixed on motherboard ! It seems to be hard to change GPS receiver without equipment (and experience !).
Will check if speaker part seems good (removing / cleaning it), then checking / cleaning GPS receiver part. Hope this will solve my issue.
I found a local mobile repair shop near my home. I asked it how much it will cost... waiting for the answer
Yeah it can be tricky to replace parts like that if you don't have experience. Good luck, let us know how you get on in this thread.

This week-end, I cleaned my i9100p hardware but nothing changed ! I noticed that without HP/antenna part, I can't fix GSM nor GPS signal. This part seems to be the heart of the signal reception. I plan to change it as soon as possible. This morning, I ordered HP/antenna part :
http://www.htcn.fr/pieces-detachees...ut-parleur-dock-galaxy-s2-i9100-sonnerie.html
I don't know if this will solve my issue, but I really hope for it !
Someone in a french forum explained me a way to improve GPS signal. This seems to be really easy to do. I will try it tonight and test it tomorrow
http://galaxys-team.fr/viewtopic.php?f=50&t=41110&p=634046#p634044
More news tomorrow !
Keep posting your progress, this thread is going to be a really useful reference for people in future once you've fixed it
I have tested the hardware fix linked in my previous post. Unfortunately, that doesn't solve my issue. Maybe because it's a i9100P (NFC version), with a special battery cover. Moreover, I made this fix quickly. Will try again later.
I'm now waiting for my new HP/antenna part, that will probably be received this week-end !
Edit : HP/antenna part has been sent by HTCN. I will received part thurday or friday. More news soon
HP/antenna part changed. Unfortunately, issue not solved
For now, I don't know what to do... It seems that the guilty is the GPS receiver (fixed on motherboard), but it's a bit hard to change. I will check again /root/etc/gps, sirfgps.conf and gps.conf, but I'm not optimist ! Phone only costs about 100€ here : ask a center to repair it is not a good idea, in my opinion.
If anyone has an idea, please post here ! It seems that I have to buy a S3 4G soon :-s
Yeah unfortunately replacing individual components on the board is really really difficult to do unless you absolutely know what you're doing - a fiddly job, very easy to damage the board itself or other components beyond repair if you mess up. And you'd have to source a 2nd hand board to get the components to replace anyway, so you might as well just swap the whole board. Samsung service centres don't replace individual components on the board because it's easier for them to just swap the whole board and they charge a lot for labour.
If you want to keep the phone, replace the whole motherboard; source a 2nd hand one online, and either swap yourself or pay a local mobile repair shop (not Samsung service centre) to swap. But you could also buy a fairly good phone for not much more than that (or even the same amount if you bought a 2nd hand phone).
So given what you've already tried (and you have tried everything), I'd probably be looking at a new phone if I was in your situation.
hi people,
the digitizer literally jumped out of my phone , with the summer heat . I went to the store and they ask for money to give me a budget that would probably be almost the value of the phone according to the employee. so I gave up the idea of fixing it and put away. now occured to me the idea of doing a multimedia system for my car with a navigation system and so. so far so good right?
here come the problems ... my pc ( ubuntu os) does not recognize it , I can not download the drivers because I do not know who manufactures it , and the store does not have the capacity to give me technical support . awesome !
I try otg mouse, I try adb tools, I try tons of things, nothing...
however, I know the phone is base on Broadcom 21664 Dual Core platform, and is running an android 4.2 version called 'hawaii' I think...
else, I did root the phone but for some reason it returned to the factory settings and is like it was first turned on.
what can I do?

Hi,
Have not used my Nook Tablet recently because have newer hardware.
Recently saw "Use An Android Tablet as a Live Monitor for your DSLR Camera" https://www.youtube.com/watch?v=JnzkHegu3aA and hope can do this with my Nook Tablet 16GB.
Searched the forum and then YouTube using Nook Tablet for camera monitor but to date have found nothing.
Hope someone else has interest in doing this.
Thanks
Ken
A search through the forum for "USB Host" seems to indicate that while many people over the years have coveted this capability, it has never been implemented on the NT.
That said, there are some DSLR cameras that use direct WiFi to communicate with Android devices and can display what they see on the tablet screen (not to mention accept remote commands from the device). These apps run just fine on the NT.
nmyshkin,
"there are some DSLR cameras that use direct WiFi to communicate with Android devices and can display what they see on the tablet screen (not to mention accept remote commands from the device). These apps run just fine on the NT" Unfortunately my cameras do not have WiFi.
Thanks for the tip about "USB Host" somehow my searches never picked it up. Redid the search using Nook tablet USB Host and got a Lot of Hits! Also Googled and got > 111K hits!!!
Clarification: Is the reason it has never been implemented on the NT a Hardware or a Software problem?
Googled and found [Q] USB Host/OTG mode for peripherals? https://forum.xda-developers.com/showthread.php?t=1546363
Answer by tobdaryl "From what I have read this is not possible yet but is being looked at by at least Team B. Others may also be working on this but it holds lesser value till the more important things to everyday operation on internal hardware has been conquered" it sounds like a Software problem.
Beginners question, if it is a Software problem can it be corrected by installing a newer version of Android?
Thanks for your help!!!

It has to be patched into the OS by someone (if the hardware even allows for it). That funky USB connection on the NT may also cause issues, not sure.
But yes, it's maybe both, certainly at least non-existent code in the OS. I looked at my tablet running AOSP 7.0 and I only saw one mention of USB Audio in the Settings section. That's a typical USB Host application (I use it on my NST--there developers wrote new code patches to enable USB Host). Just for the heck of it and because I have all the hardware, I attached an OTG cable and a USB Audio device to my NT.
Nada. Generally there has to be a setting to enable USB Host because power input/output has to be changed, drivers added, among other things. The setting I found on my NT is probably just there like "camera" and "bluetooth" are there. They don't do anything but it was easier to just let them be than to take them out and try to trace all the threads that might unravel if they were removed.
So I think the answer is still that no one ever got around to looking at it seriously, or someone did once and found the hardware was an issue.
Sorry
nmyshkin,
Thanks for checking!!! My gut feeling now it is a Hardware Problem.
Any suggestions as to uses for the NT since the hardware is so old?

I am running AOSP 7.0 (see https://forum.xda-developers.com/nook-tablet/general/how-to-installing-aosp-android-7-0-t3578665) and it performs flawlessly for me. No FCs, no freezes, no funny business. It's the best ROM I've run on the tablet (I never ran the stock).
Back when I was running CM 10.2.1 I did an AnTuTu test because someone asked about the speed of the system (which I thought was "fine"). I've never run another one, feeling they are pretty much useless. It seemed to test a great number of things I would never use the tablet for. The real question is "am I satisfied with the performance?". My answer is "yes".
My husband has an HD which I recently upgraded to CM 12. I know from working with his tablet that it is a little more responsive than mine, but I honestly don't care that much. I don't experience lag to any extent that changes my blood pressure and I'm constantly amazed at how well the tablet performs. So that's my test
