Having trouble taking apart my Galaxy S II - Galaxy S II Q&A, Help & Troubleshooting

I just recently bought a second-hand Galaxy S II after my old iPhone broke down.
I followed some Youtube tutorials and the iFixit guide to take it apart so that I could clean out all the dust and apply some thermal paste.
iFixit Samsung Galaxy S II Teardown Guide
But I'm stuck at the part where I have to pry off the back panel since there is a part of the circuitboard beneath the audio jack that bends when I do.
I didn't want to risk damaging my new phone and none of the guides I found seem to cover it so there might be something wrong with this particular
phone.
Here is a photo of the problem I'm having.

Any help with this would be much appreciated.

[Q] Replacing Galaxy S2 Screen?

Does anyone know how to replace the Galaxy S2 screen?
I recently dropped my Galaxy S2 and cracked its screen.
I went ahead and bought this part: http://www.sino4n.com/brand-new-ori...-screen-for-samsung-galaxy-s2-i9100_p489.html
But it appears that there's no guide to install it available yet. The two disassembly guides I saw on youtube don't show the screen disassembly.
Can anyone guide me on this?
Proceeded up to here but can't figure out how to get the screen off. Anyone?
The new part has some glue at the back so I'm assuming it's one of those glue things but I don't know where to begin to pry. (New part in photo is lying on battery).

Replacement digitizer - UK

Hi guys!
So yesterday I dropped my 4 week old HOX+. It only fell about 40cm but it landed face down on a solid floor. The result:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
To get it professionally replaced is gonna cost me more than I can afford, so I'm looking to do it myself. Trouble is, I can't find anywhere that stocks replacement digitizers for the HOX+.
Does anyone know where I can get hold of one? Alternatively, could I use one from a standard HOX? I know I wouldn't have the red buttons, but to be honest I'm not a fan of them anyway, they are difficult to see when not lit.
Thanks.

[Q] Can't read sim card

My friend has a Verizon Casio Commando C811. He brought it to me after running over it with his bus. I replaced the LCD/digitizer assembly (which was a major pain as compared to other phones) it works fine except now the phone isn't reading the sim card., Before I go tearing back into this thing, does anybody know what the problem is?
Maybe it's damaged?
was working before it was taken apart. The ribbon cable that goes to the sim card wraps around one edge of the motherboard to attache on the other side. All of it looks great. I didn't need to disconnect it in order to remove the motherboard. Since then I have. and reseated it to make sure.

JTAG?

If possible, I could use some help identifying (potential) JTAG pads on the new Fire HD 6. Below are photos of the board courtesy of ifixit.com ..

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The areas of the board that immediately sparked my interest are labelled JDEBUG, JDBG2, and JDBG3. I've googled the hell out of those identifiers, and have been searching for schematics for the MT8135, but information is thin - i'm assuming its because this SoC is relatively new. Does anyone have have any tips or suggestions on how I may be able to go about testing these pads? I have a multimeter and most importantly, a brain , but i'm inexperienced when it comes to JTAG and hardware debugging so any advice would be greatly appreciated. Thanks!
I found it! It's on JDEBUGhttp://forum.xda-developers.com/showthread.php?t=2991474
