I think this is more dev and hacking than general q&a. Please correct me if that's wrong.
I'm looking for a way to access the primary storage from a different device, or access another device's primary storage from the base hardware. The equivalent of removing a hard drive and putting it in a different computer. As far as I know, bitlocker is not enabled on most platforms unless the policy was enforced with EAS or SCCM, so that shouldn't be an issue. But I only have an HTC 8x to play with right now, and they don't exactly come apart easy. I can't find much documentation for teardowns of any models at all, either.
I guess this all assumes there aren't jtag fuses in the SOC, but I can't find documentation of it. I thought I saw someone with a production device that had something about fuses in an image, but I can't find it.
Since I have an 8x as well, I was thinking the same thing...I was thinking about finding one with a smashed screen to take apart.
I did just get mine back from service, and they changed the back. Therefore, I think there must be a simple "trick" to break in lol

I'm almost completely certain that it has to do with attaching to a JTAG interface. That will let you access the eMMC controller directly. I just don't know the command set, and haven't touched jtag in forever.

Has anyone else had this happening with thier G1 - we have seen quite a few of these in already that just get a blank screen. The backlight is lighting up but no video coming to it from main board.
We have swapped the boards and proved they are good - appears to be issues with the cluster-f*ck of video flex cables they are using on these. We have worked on alot of HTC phones - this is by far one of the worst designs we have seen to date.
Also, be very careful as we have gotten more than a few with broken or bent sim slot pins..the geometry of the slot lends itself to inserting on an angle and this is all it takes to bend those pins and render un-usable.
How do you do this?
I think you are trying to provide a recipe for those of us, that want a non-conspicuous reason to exchange our OTA RC30 G1s to get RC29 or earlier ones, that can be rooted, instead of our securely locked up ones.
Please provide more specific details on how to do this.
Maybe T-Mobile will add a more relaxed policy towards allowing full access to the device for those that want it, if too many get exchanged with these symptoms
I, for one, would be happy to participate in a developer program (possibly even if it had a small fee attached) and waive any warranties on the device, in exchange for unrestricted access. Sounds like a clear win for T-Mobile...

It sounds like the video problem is just the way the device was designed, you couldn't replicate it without opening the phone and voiding warranty. For the SIM slot, however, all you have to do is bend a pin and it won't be able to read the SIM card anymore. I doubt a rep at T-Mobile stores would check this, and even if they did, it's a design flaw in the phone. They could try and manually bend it back, but tell them you're worried about it happening again etc.
Edit: For the problem at hand however, you're not getting any power out from the mainboard to the screen? Are you sure? If you aren't, then it wouldn't be a problem with the mainboard, but you said replacing that had no effect.
So my awesome Venue Pro with an already sketchy battery is giving me trouble.
It has only happened lately. I'll turn on the phone from standby in order to, well, use the phone. But 95% of the time, the screen will within a split second go black, showing nothing on it. Funny thing is, every key works and illuminates and you can even interact with the touchscreen as I noticed it made sounds previously when I just started moving my finger along the screen, same with powering it back on when it likes to actually show what's on the screen and it'll be on a totally different app or screen itself.
Because I bought it on eBay, Dell, very ignorantly, is refusing to even deal with me in regards to warranty despite the phone being manufactured this year, so I'm hooped for sending it in at all for repairs.
If the touchscreen technically "works", then what could be the problem?
Thanks for your help, guys.
You might want to google something like "dell ownership transfer." Seems to me there was a way to transfer the original warranty term to another person. If you can get in contact with your ebay seller, he may be able to help you out.
Short of replacement, I say the first thing you should try is opening it up and making sure all the cables are connected internally.

The next step will either be re-flashing the original stock 7.0.7004 rom in hopes that it's a software problem (unlikely if you ask me,) or ordering another DVP off ebay and swapping parts until you have diagnosed the problem.
That's the issue- My eBay dealer didn't actually buy the phone himself. He took them as a donation for his not-for-profit business so the proof of ownership is pretty much MIA.
I'm starting to believe the backlight is failing or something close to that. Possibly due to the slider being used? Not any more often than someone else would use it, though. I looked at the disassembly guide and it's something nearly impossible with my lack of tools or understanding.
I'm pretty much hooped then?
Wow, shady. I bet he took advantage of and offer like this and then just sold the phone for profit.

I can't think of any other ideas personally. Selling it off for parts seems to me like the best course. If you decide to do this, you should wipe your phone with a soft reset as you normally would when selling this phone (in settings > about > more > reset my phone.) If what you're experiencing is a software problem (which, again, I very much doubt) this might fix it. If not, your personal data is gone, and you're ready to sell it.
You may want to let the other forum members weigh in on this, but I don't think there's going to be an easy fix that doesn't involve disassembly.
I have attempted a reset + restore and whatnot, so most likely it would be a disassembly issue then.
The issue with me taking it apart would be that I'd probably do more damage that way lol.
Hi,
I accidentally crushed my photo between a seat and a table on a train. (htp://imgur.com/Q1RUsEk) This is what it looks like after it was crushed.
Immediately after it was crushed, I noticed the phone network icon was empty. I turned off the phone and it has not been possible to boot back into the home screen since then.
I attached the phone to my computer and used ADB to get (htp://pastebin.com/H85Xq2U4) the last_kmsg, (htp://pastebin.com/NArZYWSZ) logcatouput, and (htp://pastebin.de/124812) bugreport output.
I'm not an expert at debugging problems with phone hardware but it looks like there is a problem with the audio subsystem in logcatoutput.
Are there any reasonable steps I can take in trying to resurrect my phone?

According to your log description it would seem that there is physical damage to the system board. The only option would be to do an inspection of the phone. This will require dis-assembly and that does need some skill, although there are several threads here on XDA that might help.
Determining the actual board damage would require some knowledge of electronics.
I would suggest that you look into replacing the unit. With the Nexus 4 you might be able to find a used unit on ebay or on the Swappa forum here on XDA.
Your sign-on doesn't indicate a location, so you may or may not be able to access/use these sites. At any rate you are looking at some pricey repairs, if such repairs are even possible.
good luck.
Hello xda-developers forum,
I realize this has been asked before, and I've read through many threads here and elsewhere, but I'm not getting a definitive solution that works for this particular situation.
Here are the details:
Phone Model/Make: Google Nexus 4
Carrier: Wind Mobile (Canada)
Screen is cracked/broken, completely black.
USB debugging is not enabled.
Completely stock ROM, have not made any customizations to the phone.
I have adb set up on my laptop, but don't know how to proceed in terms of loading into bootloader (?) and flashing, pulling data, etc.
Mostly only need to retrieve photos and videos. Already synced with Google for contacts (but not photos, unfortunately).
If you need more information, please let me know.
Is there any way I could retrieve the photos or are the precious memories lost forever?
Thanks in advance!
I dont know what cause you that problem.
but i suggest you to install driver on the computer and with tool box install stock rom in your phone.

Installing stock ROM would wipe his device, if he were able to, which he obviously can't.

A new screen should work, as long as that's the only thing that's damaged. It's up to you whether it's worth the $45 for a new screen assembly or $60 for the entire front unit (less frustration and possibility of screwing up than just the screen assembly) to save the photos on your phone. Those are USD amounts - I don't know how that translates into Canadian or if shipping will be extra. Swapping screen assemblies on the Nexus 4 is actually fairly easy - especially if you buy the assembly already installed with the bezel. I've done it myself probably 20+ times trying to get mine to work (I eventually did). There's plenty of teardown guides and videos on youtube on how to do it. Get yourself a new battery while you're at it, for $20. Maybe you've already replaced your phone, but either way you can get practically a new phone for $45-80 depending on what you want to replace, or a cheap back-up (always good to have) for whatever you've replaced it with. Plus all your precious memories back.
You cannot unlock the bootloader without losing everything so your best option to restore important data is to replace the screen. The battery is glued pretty hard to a breakable piece so watch one of the YouTube videos and decide what all you want to replace. Ifixit had a good video that I used when I had to replace the logic board in mine.
I'm totally stuck. I have a work laptop that requires a corporate email to login to the laptop. I now want to use the laptop for my personal use and remove ALL corporate restrictions etc.
I have done everything I could think of (including a complete format, removing the battery CMOS and regular battery, and messing with the BIOS and other preboot configurations), but nothing works! Eventually, the computer goes back to the original windows startup screen requiring a corporate email to login.
It's almost as if there is some sort of hardware or hard coded programing that ensures the computer uses a corporate email to gain access to the laptop.
I almost feel like even if I buy a new HD and replace it, the problem will still exist.
Can anyone please provide some insight?
Is a Lenovo Carbon X1
Thank you....
You already answered your own question unfortunately my friend.
Hard-coded into the CMOS.
Google "short circuit SDA & SCL pins on security chip" for your EXACT make and model.
I had success with a ThinkPad p41 recently.
Failing that, you WILL have to talk to the sys admin from your job, as they have the unbinding protocol for every PC bound to their network.
That kinda security is EXTREMELY difficult, usually impossible, to circumvent without the unbinding protocol.
Best if luck, and post back if you are or are not successful, or have more questions.
Promise I'll answer WAY faster than 2 weeks next time, ok??
Oh, and buying a hard drive definitely won't help! Lol! Because again, it's hard-coded into a security chip right on the motherboard. A chip that contains non-volatile memory, meaning even if you remove the battery it's still there!
That's the reason the only POSSIBLE workaround (it's a hit or miss kinda thing...) without the unbinding protocol is shorting most two pins out.
Now I stated in bold letters EXACTLY your make and model, because not just Lenovo, but most companies tend to move those pins around on the security chip, from model to model, year to year, ON PURPOSE, because if you get the wrong ones The security chip will release a puff of the stinky magic smoke, and your motherboard is finished.
Just take your time you'll be okay, so long as you didn't drink a pot of coffee beforehand! Lol!
