So I have had some issues with my Touchpad that I am currently troubleshooting with rr5678 (thanks) in this thread http://forum.xda-developers.com/showthread.php?t=1483066. But it is looking more and more like my memory is corrupt and will need to be replaced. Does anyone have any idea on how to replace the memory or will I have to replace the whole main board? Also, if it is possible to replace only the memory, can I buy an upgrade in size? I watched this video on how to do a tear down which I'm very comfortable doing. Looking for options.
Check out the hp touchpad teardown on ifixit.com also another good one is here

Youll see that the memory is not replaceable.

I've been reading about upgrading the 2gb SD card that comes installed in the Streak. Apparently there are two potential benefits of this.
1) A larger card of which the extra space can be used as storage for media, etc. The problem I have with this is that it appears to involve some serious jumping through of hoops to make it work and it doesn't seem to always work. In other words, it is very easy to screw up.
2) Faster card to improve performance.
Has anyone tried this and have any feedback on whether it has had any effect on overall smoothness or stability?
I'm going to be replacing my screen soon so while I have the Streak open it would be a good time to replace it if there is anything to gain. From what I have seen so far, it doesn't seem worth the trouble, but if anyone has evidence to the contrary, please speak up.

I have posted about internal card replacement, external card replacement, screen replacement here at xda and at 2 other sites. A forum search would have found it here and a Google search would have found it elsewhere. I don't have the time to keep re-posting my posts.
Sorry

When you create the title for a new thread it does an auto search. I think the title of this thread is a pretty reasonable search topic. The auto-search gave me nothing useful. Yes, I did bother to look at what it brought up. One title looked promising. I read it. It didn't help.
Besides, if you read the post, I obviously have read threads on the topic. Did you think I just created my opinion from whole cloth?
I'm looking for feedback from anyone who has good reason to think it is worth doing, because at this point I don't believe it is, but since the phone will be opened up soon, if that opinion is mistaken I would like to know about it so I won't miss out on a worthwhile hardware mod.
IF you had done a search for INTERNAL sd card you would have gotten all the answers you need.
So while I am here I will mention that in MY opinion it was well worth it, although I took the simple route and just cut a small bit of plastic that retains my internal card to replace it with the 4GB class 10.
Access to and from the card is greatly improved. What is in your Streak is a class 2 card which will read at about 8-10 MB/s and write at about 4 MB/s, on good days. Real world, knock a couple MB/s off each.
The Class 10 4GB, read speed 16-20MB/s consistent and write between 9-11MB/s, so do the math.
True, under normal conditions it may not seem as much, but I work with a lot of photos and documents out on the road with my phone. The time it took to replace the card has been saved countless times, and for me time is money.
The thread that Adam and others are using for development level conversations about the unlocking of the bootloader is awesome, but it goes over the head of many of us enthusiastic noobs.
This thread is so that we can try and move our questions and confusion to here so as to un-clog the other thread.
It looks like the only way to bypass the bootloader we have seen so far, is to perform a hardware mod. After the hardware mod, we should be able to boot from SD or reinstall the ROM.
Discuss!
If i first get to have the chip from outside USA i surely will go for it, if its totally worthy.
Really, for me, it depends on just how involved the hardware mod is---whether it requires soldering and such.

I wouldn't mind doing it myself, no matter the level of difficulty. Also a send-in service by some 3rd party company (N2A comes to mind). We'll see what the success rate is, and what can be done.
I already opted for $50 more than the KF, then another $40 for a 32gb sd card... i cant see spending even mor eto buy the mod chip. At that point, i shouldve bought a better tablet.
I'll wait on a software bypass, it'll get here eventually.
Plus, i have no interest in linux. I doubt i even need ICS, but if it comes and its free... why not?
From what I have read so far the hardware mod would not be challenging or expensive. Two screws and 4 solder points. According to Adam the chip is only $3 USD, and I would assume that it could be programed with a printer port.

I think the cost of the SD is irrelevant. You would have to do this with any tablet, and if your comparing to the KF then this one section of your argument is even more so invalid.
The mod chip also looks like it will be very inexpensive.
EDIT: I highly doubt ICS will be released for our tablets by B&N ever... So we will be waiting for someone like the CM team to get it working for us.
The hardware mod interests me even if solely as a way to learn a bit about embedded security. I do find it unsettling that I can't install linux on my linux computer.
I don't want to be dependent on having a boot sdcard installed at all times. A hardware modification is good ONLY if it leads to PERMANENTLY disabling the anti-hack mechanism so that the hardware modification doesn't have to be performed again every time the device is booted up.
I would accept precisely this;
Plug in some device,
Boot on sdcard,
Modify the secure boot process WITHIN DEVICE STORAGE (not within RAM),
Remove device,
Store on shelf until it is needed for another hacking project.
There are multiple options for modification of the secure boot process, in particular, replacing the signing keys stored on the device allowing us to use OUR OWN signing key to satisfy the secure boot process. Another option is to eliminate the signature check. I believe that the former will be simpler since it is just a DATA modification rather than reverse engineering.
I wonder if the hardware has an equivalent of "S-OFF" that HTC phones have? As I recall, on most HTC phones, there is a ONE BYTE EDIT that has to be made within one partition of the eMMC to TOTALLY disable all of the device's bootloader sig checks and hardware write protect. The issue was that the partition in question would be hardware write protected. Presumably, with the hardware modification for NT, a similar state *should* be achievable.

Absolutely not!
I also wouldn't because you never will get your in the same condition as it was before you opened it and everybody can see that you did something to the device. You also don't have warranty anymore after that process.

Whaaaaa???
Unlike you, most intelligent people will select jeweler's tools to open something like this rather than a crowbar and a sledgehammer.
Further, most people would actually perform the modification using a temperature controlled and grounded soldering iron, rather than an acetylene torch, thus no damage caused even internally.
As far as warranty goes, it is EASY to restore it to factory condition, unless you use the Neanderthal approach to hardware modification, in which case warranty provision is determined by YOUR HONESTY to only warranty it for something that YOU DID NOT CAUSE (in which case there is no morality issue to be worried over).

Soldering is not that big a deal once you have developed the touch. I am fairly certain that I could solder the four wires required for this chip and then later un-solder them and no one would be able to tell.
It's a great device regardless of installing a ROM. I just rooted it and installed the gapps and OTA block. I still have all the B&N stuff and everything work fine. I have all the apps loaded I want (that make sense without gps and 3g) and I WOULD hardware modify this puppy in a heartbeat to get back what I have if B&N happens to force an OTA through that took away root.
I have been having a lot of fun trying lots of different apps and schemes. The hardware mod is easy and I have already taken it apart and looked at where the soldering goes and it is back together without a hitch.
Big hand to the devs who are doing their thing so we can do ours.
Bill
Oh yes, I'm sure he had a rock and mallet in mind for the modification. How neanderthal of him to suggest that hardware modification is well out of his, and many other's, reach.
It's easy to unroot. I doubt physically messing around with the internals using any manner of ultra sophisticated museum art thief tools will leave behind changes that are unnoticeable.
Duely blundered from my thunderdolt
I would do it just to do it. I am one of those guys that just like to mod stuff for the hell of it. No, I'm not very good at creating any of the mods, but if it will make my experience better and it's not rocket surgery, I'm game.
As for the warranty issue and opening up the case, it really doesn't look like its that big of a deal. I am guessing that with a set of precision screwdrivers and a guitar pick it can be opened simply and be very nearly undetectable. Besides, if I am going to open it and solder it, I am not worried about the warranty anyway. If someone IS worried about it, then they shouldn't be doing anything that will void it.

My TouchPad was acting wonky so my friend tried to follow the YouTube instructions to open and fix it. Not surprisingly, he did not have the skills to either fix it or put it back together.
Does anyone know of a business or individual who repairs the HP TouchPad in Toronto? I would like to get it working again as it was my testbed for new ROM's, apps, etc.
Thanks in advance for any information.
You say Touchpad has gone Wonky while I'm not familiar with that fault. There is an app called Ifixit and there website which gives detailed easy to follow instructions on repairing various Touchpad faults.
Certainly worth checking out. And you will probably get more advice here if you can be a bit more descriptive than Wonky .

Let me clear then. My friend thought there was an issue with the digitizer and then used a thin instrument to gently pry the screen from the TouchPad, exposing the insides. In doing so, amongst other things, he disconnected the ribbon connector, linking the screen to the guts of the tablet.
I am looking for someone who can:
1. Reconnect and close the TouchPad in a way that returns it to function.
2. Optionally, if the TouchPad still does not allow touch input, diagnose the reason and propose a solution.
I have looked at iFixit and many other sites relating to the TP. However, I do not have the hands to do this myself. While I appreciate your feedback, I was not looking for help in diagnosis but for directions to someone with good hardware skills who works on the TP.
Thanks.
I'm a little over a month into owning my moto360v2(46mm) and I find it a little disheartening that nobody has torn one down to figure this out yet(I'm guessing that like the last version, once we figure out a way to attach USB to it everything should get easier from there). It sucks that someone like ifixit hasn't shown a breakdown at least. I have not been able to find much other than the standard info about the guts of this thing.
I would love to grab a "cheap" 42mm or even a used one to tear down a bit and document. IF I got my hands on an extra watch one way or another I would definitely use it for research purposes and employing the help of the greater android community to figure this device out. If you have a used one you would like to donate let me know.
Has anyone found internal documentation on it that I might not have found?
So i'm in the process of converting all of my cars to cars to android. I am having quite the time actually getting units that aren't defective or used in some way. This one came w/ a harness cut so short it's nearly useless, it has SU on it, a bunch of the previous users documents, his phone pairing info, his email account, gmail account, misc documents/pictures, nova launcher, Pandora account, Xposed stuff, etc. Joying took in a return and didn't even look at the damn thing and just sent it back out to another customer. Nice job joying! Anyway after all this I wanted to see if they hacked anything inside and I found this thin 36ish AWG wire soldered between two resistors. I am unsure if this is a mod or stock. I cannot believe joying would do this however the solder job looks quality so I don't know. Can anyone tell me what the purpose of this is if it is not stock? I've probably going to send this back given the circumstances but I'd like opinions on this wire.
Thanks guys.

All I can say is I bought a new unit from Xtrons and it was new and there was a very similar thing on the board mounted behind the touch screen. No idea if this will actually help you but based on all the other crap that is on the unit I would definitely send it back and ask them to pay for the postage as well.
I've looked more thoroughly and there are also resistors missing, I'm fairly sure this was modified by someone. I'd really be curious if someone can tell me what this person was up to here.

It may be a last minute-change to the circuitry on the part of the manufacturer.
I have seen some similar things here and there in the past, where you purchased the last run of the "old-style" circuits that have to have a few extra traces or runs included, and the only way to do that is to install a jumper, leave out a few components, do some extra manual soldering, etc.
If it functions okay, and you're not noticing any critical defects in the performance of the unit, I wouldn't worry about it if I were you. There is a very low likelihood that some end-user would simply go in and start desoldering things and throwing in jumpers, and you get a product that still functions in good order. The average Joe would simply break it doing things like that; the person who did that knew what they were doing, even if it looks somewhat unprofessional.
(If it works, don't fix it.)
Spoke to the vendor and they told me they did not do the modification.
Dave
I cant see anything that doesnt look like it wasnt done by the factory, does everything work ?
Resistors are missing and a jumper wire has been added. I would hope they wouldn't have left it like that. Regardless Joying says it was not done by them.

Missing, or just not been added because they are not needed on your version ? Nothing looks out of the ordinary to me. Joying are sellers, not a factory so I doubt theyd have done anything internally to your unit. Does everything work ?
The pads appear to have solder on them. The device also had someone elses data on it. There was no way I was going to accept this as a new device.
