Hi Guys,
Took the liberty of doing a teardown for all of you.
For those following along at home:
Take off the back plate, remove the battery and the SIM card.
Remove all screws (4 on the bottom, 2 in the middle and 2 at the top. Be careful not to strip them!)
Using a guitar pick or case opening tool, remove the bottom plastic piece of the phone. Start at the top edges where the plastic meets the side.
Using the same tool, remove the top plastic piece of the phone. This is incredibly tricky! There are 4 plastic clips on the back and 4 on the front, it is also held in place by adhesive. It wasn't incredibly hard to get off, but insane to get back on (I broke mine trying to get it back on and glued it into place)
Using the clearance given to you by removing the top and bottom pieces, slide the case tool/guitar pick down the side and pop the phone apart. This sometimes requires quite a bit of force and a bigger guitar pick.
Remove the back plate and see this...(image 16 on attachments, I can't post links yet ) Pop off the ribbon cables indicated at the boxes using the tool. Lift the main board assembly out of the phone.
The main board is two levels and held together by thermal adhesive. Slide a guitar pick in between the two levels to carefully break them apart, taking into note that they are connected via a ribbon cable which needs to be removed once they are unglued from one another. This is the top level with the heat shields removed: (image 5 on attachments). The bottom with the heat shields removed reveals the main board. The front of this board is picture 3, the back is picture 7.
Remove the two black screws at the top and use your tool to unclick all the clips on the two sides of the shield. Ensure to remove the antenna cable before lifting it out. When removed, the shield is in picture 9.
Picture 10, screen assembly
Picture 12 is the two top and bottom caps
Picture 6 is the first plastic piece you remove once you take out the screws and the caps.
Conclusions: The Optimus uses 16 GB soldered on HYNIX NAND for storage, and not a SD slot like many of the other manufacturers opted for. I have no idea what the 3rd "dot" is on the light sensors on the front, but unless it is the smallest camera ever created, I sincerely doubt it is a front facing camera. (top left of picture 9).
Thanks for reading and I hope this helps some of you guys do repairs/make a device purchasing decision! Feel free to ask me any questions.
Amazing. And to think I spent the last five hours looking for a teardown (see the button problem thread ). Thank you so much for this. I have one question. Were you able to take off the front keys, specifically, the start key? And does everything work again after putting it together again, if you have done so already?
So the start key is separate and comes out when disassembling. The buttons appear to be part of the screen unit and come out easily. The phone went back together perfectly, the top plastic piece is impossibly hard to reattach and i broke a couple of tabs off. It basically has to bend back into place, very frustrating.
Thanks Andrew. Good one. I was able to use your image to share in one of the post the part that was changed when i had a Bluetooth problem.
Thank you, thank you, thank you. We finally know. I'm not sure why I wanted to know so badly, but I just did. I am pleased to hear that LG opted for the all NAND solution and 16GB. Bravo.
I wonder whether MS has some kind of restriction that if you had no SD slot at all it needed to have a least 16GB?
great stuff
has anyone worked out what the 3rd dot/hole is for yet?
what do you mean by 3rd dot / hole? Which image is that?
hi gurucanto
sorry i couldn't actually locate it in the pics there...probably just me being dense.
but it's on the faceplate where the other sensors are. there's proximity, light and ?
3 holes
It is in picture 9, the top left black piece is the ambient light sensors, and there is a 3rd sensor of some kind there. If it is a front facing camera, it is really, really, really small for a camera sensor.
Can you post the part number of the Hynix NAND? It would be interesting to compare the specs with an SD card.

would be nice to know.

Don't have the phone anymore guys, sorry! Can't post beyond what is already here.
Has anyone figured out what the third sensor is?
Hi guys, first of all I want to post two links that refer to the schematic of LG optimus 7 e900 and e900h... maybe can be useful (you can understand what sensors do).
Because I'm under 8 posts so I can't directly post links... see the attached file
Now a question
I just broken my digitizer I bought a new one on ebay. The only thing I'm not really sure is: HOW DO I REMOVE THE TOP CAP? I watched all the pictures but I'm so scared of break it!
Thank you guys

WOW! :O
Those manuals is amazingly detailed.
Oh, and if by the cap, you are referring to the black plastic that also has the power button, then it is held in place with hinges, and I think the OP also broke it while he was taking it apart, so I am not sure what the safest way would be...perhaps use an iPod opening tool? Definitely want to stay away from metal tools...
I can't post links yet (commmmmoooooon) but if you want go to ebay.it (italy) and type this: VETRO SCHERMO TOCH SCREEN VETRINO LG E900 OPTIMUS 7
So you can see what I bought... as you can see there's not the top cap, but if I'll be gentle with it... I shouldn't break it
Anyway thanks for your reply

According to the pics in the service manual that ripp3r posted earlier the part number of the NAND is: H8BES0UU0MCA or H8BESOUUOMCA (zero or O )
But inside of the document when searching for Hynix I found some another part number:
H8BES0UU0MCR-4EM (NAND 4G / DDR SDRAM 4G ( Hynix)) and
H8BES0UU0MCR-4EMNAND/4GSDRAM/4G(2G*2/32bit)1.7VTO1.9V13.0x10.5
x1.2TR137P---HYNIXSEMICONDUCTORINC.
Hope I could help
The Hynix is the RAM...the NAND is Toshiba branded...
okay sorry, I was just searching for Hynix. I figured that there was something about SDRAM but that's no reason to feel offended. (if I got the '....' right)
In the replacement list it says: THGBM2G7D4FBAI916GBYTE0VTO0V12.0x16.0x1.2TR169 PMLCNANDBGA TOSHIBAELECTRONICSKOREACORPORATION
So kapanak is of course right with Toshiba because it says 16GB in the name.
LOL! Hahahaha...
The "..." is just a habit I have developed over the years, it meant nothing. My post was completely devoid of any emotional implications. Just stating a fact. And thanks for finding the part number. Now we just need someone to run that through a database and give us an idea of the specifications.
Have a brand new TPT. A couple of days someone broke the screen. Still functions, but there is a huge crack in the middle of everything. Sent the tablet back to Lenovo to get it fixed under warranty, but they called today and said they could replace the screen for only $750, when only paid less than $500 for it origionally. Getting them to send it back not fixed, but now I need some guidance on how to replace the screen myself. Any suggestions on where to find a compatible screen and how to replace? Any help would be appreciated.
There are YouTube videos on opening and installing a 3G card. The screen and its connections are shown during the video. Try to find one cheap, that is also broken, but with the screen in tact. Alternatively just get a good used TPT.
Thanks so much. Figured out how to take apart, but new to all of this so not too sure about what to do next. Scared that it may be booby trapped or something. Also I am having trouble finding replacement screen. Can only find 1 on ebay and it is not very descriptive and is in hong kong. Anyone have a broken tablet for sale?
Hong Kong makes sense. What's their rating? If they're new I wouldn't do it.
They have a 98.9% rating and they are ebay top seller. My problem is that "IBM Lenovo Android ThinkPad Tablet 10.1 inch lcd screen display" is my only description. I don't know if it is the right screen.
You could email them asking for specs. OTOH there is only one Lenovo ThinkPad Tablet that's Android. Feel fairly sure that the screen is the same across models.
Also, check the Lenovo forum. Lots of folks there - maybe some one has a broken TPT.
Hi all,
this morning I left my tablet at home and when I come back found it with broken glass (I think tmy little brother dropped it, but he doesn't confess)..
Sometimes touch works, more often not.
However.. What can I do? I read that some lcd are not glued properly, and it could be my case, because on the left it's a bit lifted on the center.
In your experience, is there hope that it can be repaired for free?
And if not, where can I find replacement (I only found this: http://www.powerbookmedic.com/Google-Nexus-7-LCD-and-Digitizer-Assembly-p-22606.html , but it isn't available)?
Thank you!
sooooo sad! :/

At this moment you have Two Options..
1. Sell it on Ebay for Parts you probably get about 50 to 100 at most.
2. Pack it up and store it away in a closet and forget about it. Until the Screens are being sold as parts.
the reason for both options is due to Asus not selling the LCD/Glass at the moment as a Part.
they are still manufacturing the Nexus 7 and soon will be making the Nexus 7 with 3g capability.
so there biggest priority at the moment is to keep making them.
you can send it in for repair with Asus but it will cost you about $160.00 just to get it repaired.
not to mention how much it going to cost you to ship it to them.
is the device frame cracked or damaged broken is the back scuffed or cracked .. Does it look like its been dropped. IS THE Crack on the left side. CAN You post pictures. Answer the above and give some pics and more info..
i know you do not really know for sure .one more question was it moved can you tell for sure rather someone was using it or not ?
If you really feel it cracked laying where you left it . Without anyone touching it . CALL GOOGLE PLAY.. But please do not be dishonest . There is a issue with the screen lift cracking and becoming unresponsive . as well as backlight flashing issues..
Looking forword to seeing pics and more info
Hi XDA!
When i got my nexus 4 i noticed that the back glass panel was (in my opinion) not secured correctly. It flexed on the the left hand side of the device, if held normally,in the general area of the camera and flash.this was its first drop and even so it was nothing major by height ect. However it was in the back pocket of my cottons and i tripped and the kerb was a bit taller than expected ^^ and my phone fell out and cracked on that panel of glass directly where this flex was.I do not feel that the glass was also strong enough as i have gathered far more scratches on the back than my friends xperia z which of course has dragontail.
I have 2 questions now
1. Should i contact google and if so how would i go about doing this
2.Is it sheer luck or influenced by this flaw
Thanks ^^
Contact Google and get a replacement.
If you search, there was someone who had a similar issue and his back cover cracked and he asked for a new device from Google.

If you're within 15 days of purchasing it you might be able to get Google to RMA the phone if you don't mention dropping it. If not you will have to send it to LG for repairs at your expense as the glass cracking isn't covered under warranty especially since you dropped it.

Hi!
My Oppo Find 5 screen broken suddenly after a gently drop yesterday.
I tried to search for support in europe but i had no luck. I would like to replace my screen with a working one cuz its totally off, just displaying stuff but touch not works.
If anyone know something about screen replace in europe, or the exact type/model no. of the screen , i ll apprecciate any help about it.
Thank you very much!
G.
Sorry to hear that... :/
what says ebay ?
Oppo europe says a new screen costs 170€..
Back cover is also getting replaced.
Keep in mind your phone gets repaired in China and its not available for over 20-30 days..
I also have a little scratch from falling in the top right corner but i can deal with it cause its invisible with my case
