Picked up a nexus 7 2012 to repair. tried to flash ended up screwing the bootloader. Not a issue bought a new board for it and swapped it out. With the new board it wont boot up unless you slightly press on the tegra3 chip and when it does it is mostly normal but all brown color seems to be missing. any ideas? ill post some photos later.. about to give up this thing is pissing me off.

Click to expand...
Click to collapse
That would piss me off too... I'm at a loss

I would send back the new board.

broken screen, need help.

Well my HD2 is now a paper weight not due to a bad flash, but because the touch screen no longer work.
The screen is cracked and a piece of it is missing, I'm not sure if i should order lcd screen, digitizer, or both. I attach a picture of the crack in hoping someone with some knowledge can help me out.
Also does anyone know of a place in Long Beach, CA area that can provide screen/digitizer replacement service at a fairly reasonable price.

$89 screen repair
Saw this on ebay might be worth checking out. http://cgi.ebay.com/HTC-HD-2-Broken...0576654092?pt=Cell_Phones&hash=item2a0b35130c
Don't know anything about the place just thought I would pass the info.
thanks for the info. I'm going to try to find a local dealer first before i start shipping things out.
That looks like a digitizer problem, does the lcd screen turn on at all?

[Q] Black spots on nook color screen

today when I powered on my nook color I noticed it has big black two spots and some distorted lines. Here is the image:

It also looks like the screen cracked (white aslant line), though I have to say the front glass is perfectly fine (not even a scratch). I haven't used it for about a week and I don't remember having it dropped during that time. Does anyone know what is it? Is it even possible to have broken LCD with front glass being untouched?
I'm in Europe right now but I have valid warranty - does anyone know if there is any B&S support here or I have to send it to my family in US?
Wow looks pretty ****ed up.
Wish I could tell you whats wrong but to tell the truth, the best thing I could give you is a guess...

Yup. You're screen is pooched. You can try and find a 3rd party screen replacement overseas, but your best bet is to send it back to the states and see if you can get it repaired or replaced under warranty.

Removing the camera unit from SGS, please help!

Hi,
I'm thinking of removing the Camera unit from my phone as camera mobiles are not allowed in my office.

http://www.ifixit.com/Teardown/Samsung-Galaxy-S-I-9000-Teardown/7122/1
http://www.ebay.in/itm/Opening-tool...4?pt=LH_DefaultDomain_203&hash=item416585c42c
Based on this, I'm confident that I can remove the camera from the mobile. But after removing the entire chip, will the phone have any trouble in booting?
I mean, while the phone is booting, will it be looking for camera unit and will fail in booting if there aren't any camera units found? I know this doesn't make any sense, but still I don't want to take any chance....
XDAians please shed some light on this topic! Also if you have any tips on removing camera, please share your information.
Thanks
Removing the camera is very easy if you know how to take the phone apart (don't break the tabs on the chrome trim).
And the phone will boot just fine.
This is my first time removing the panel. Hope it is as easy as you say.
And I'll look out for that tabs on the chrome trim.
i have changed the Mainboard a few weeks ago.
The hardest work was to split the cover.
Here the guy use a tool

i suggest to use your fingernails.
Second, there is a small white cable between mainboard and the board in the bottom.
Don't crush it, when you reassemble the phone.

Weird lines on screen

Well, it started yesterday and it keeps driving me nuts. It's present both in the system as well as 4ext or even the splash screen so it is definitely a hardware issue. Is there any way to get rid of them because my contract ends in november but I was going to stay with my DHD and get myself a PS3 (very nice offer from my carrier)
It looks like that, it's not a screenshot but it looks exactly like that:

what seems to be an officer problem?
the faint horizontal lines on the screen. That is only a picture but live they also flicker.
You could try replacing the screen yourself, but it could happen that the gpu is the problem, in which case you can't do anything on your own...

I remember having the same issue right after I bought my DHD and I remember rooting and reflashing it helped I recently changed my Radio software, you think it might have anything to do?
It's not hardware. I get it on the current versions of the 3 kernel. Synergy said it was to do with fb (not sure what it is) and he's working on it.

FB....hmmm....frame buffer (only thing that comes to mind except FaceBook) Anyway you're a life saviour man! I was worried that I will have to get a new phone.

Two Nexus 7 stuck in bootloop

I got an email from my aunt today and both my niece and nephew's Nexus 7 tablets wont boot up anymore. I think they took an update that bricked them both. They are codenamed grouper which I think is this 2012 version right? Anyway, Ill attach a picture of what they look like and maybe it is a common enough issue that the people here on this subforum can help me out on what to do I have used a Nexus before so I know how to do fastboot commands and ADB stuff and can push a ROM and kernel that way, but my aunt tells me that neither device will come up on the PC when plugged in even after downloading the newest drivers. Ill see for myself tomorrow, because I doubt she downloaded fastboot and ADB drivers to try. But figured I would post here about it and hope I can get some answers to start me off on what to do when I pick up the tablets. Both tablets are fully stock so no unlocking or rotting done to them, they were purchased last year.

I got them working. It had some issues because it kept saying invalid argument when I tried to flash stuff, but I eventually got it and now they are working again and both running unlocked with CM11 M9
