I previously bought a used prophet.
It was working fine when suddenly it randomly wouldn't take any touch command on the screen (when i click with stylus nothing happens)
I opened it trying to fix it, found out the flat cable between the board and the screen was previously damaged and soldered.
Now i ended up with a damaged flat cable and a damaged battery contacts part (the part that has the battery contacts on the board) which broke off.
Do you guys think I can find these parts? and is the flat cable a replaceable part or do i have to change the whole screen?
Any suggestion is most appreciated

You can get the flat cable separately (no need to change the LCD if it is still working).
The battery contact on the PCB will be a problem. How handy are you with a soldering iron?
PM me for more details.
evenin all, ill keep it short,
the mini usb connector on the mainboard has broken off, some of the solder p=ads are damaged, i need a replacement mainboard, can anyone help??
thanks in advanced

I suggest you try to post a Wanted ad in the Marketplace section. If anyone has one to offer, that's your best chance.
I´m sure I saw today someone selling Universal parts, not sure if motherboard...

You may use some thin cable (to use as jumper) in case the pads are broken and connect to nearest point.
Also you can buy a cheap card reader which has the same mini-usb connector. Desolder it and connect to the uni if your usb connector itself is broken.
the USB connector itself is sold on eBay for around $5, works very well on Uni or any device with the same connector. However, if the pads are damaged, it might be impossible to have one reattached.
I can offer Mda Pro's motherboard. Working good. Once fell down and display was damaged..
Message me if good for you.
yeah, some of the pads a fubar, thanks for the help people
Broken USB repair
I notice you live in the UK, I can fix the USB connector for you. Even if the pads are missing there are some test points on the board that you can solder fine wires to. I have done half a dozen of these repairs so far, this seems to be the most common problem with the Uni, even more so than borken screens. One of these days I'll have to do a 'how to' guide for it.
that would be nice, my soldering skills are up to the job, i just dont know how too, if you drop me a pm or something we can discuss it further
thanks
Guys, if you could jot down what you do and perhaps a piccy of the solder points, this would be great to put in the Wiki.
Hello people,
If its any help, my usb connection came off twice. both times it was resoldered back on with a standard soldering iron with the tip made to a point, and it still works OK. I found it easy to do, just needs a steady hand.
Regads

thats all well and good. but the copper pads that are used to solder the connector to the mainboard are fubar, so no amount of soldering will help
Seems my USB port needs replacing, I first thought I may have had some lint or something inside there as it wouldn't charge but after checking with a flashlight one of the pins had bent completely.
The only thing I can find for the original desire is eBay ID 380759842289
Can anyone confirm if this is right, or where I could purchase one from the UK.
Are they hard to replace? Would it just be the case of removing the 2 lower t5 screws, taking the antenna out of way and then what? Are they soldered on or ribbon cable?
Cheers
I had a similar problem, my device couldn't connect via usb but it was able to charge, so my first thought was the same as yours (about the lint). I tried to clean it and I found something like a little wire which was out of its place.
I ordered a usb port (about 1.50 euros) for that model and I followed this guide on youtube to disassemble the device /watch?v=8sYB_AM_jHE
You have to dissolder the old one and then solder the new which is a little bit tricky. It Worked!
For the replacement parts you can search on ebay for htc desire g7 its the same or use google you will find a bunch of them.
Somehow I broke the white connector tab that attaches the digitizer to the left side of the motherboard. I've opened it 200 times before but this time the tab came loose from the motherboard completely. Does anyone have any experience with this issue.? Also the antenna port in the upper part of the motherboard just pulled off when i pulled up the connector so now that is completely unsoldered from the board. im starting to think this phone is done. any body have any recommendations? its basically just unsoldered connections..

I have a Nexus 7 2013 16GB Wifi Model, and i bought it to a local repair shop. But it seems i was ripped off as the repairman could not repair it.
I noticed that some of the circuits are missing from my Nexus Logic board and Nexus no longer boots up.
Can anyone please help me determine these circuits? Here is a picture of the logic board.
All that is marked with a yellow star in the picture is what i am asking about...
Code:
drive.google.com/open?id=0B7LGwJIcFvH1WUtyNWZSTnhYRFU
And also are these parts important? Will the tablet work even without it? Where could i get a replacement of these parts?
Thanks in advance.
P.S Sorry for bad ernglish
What was the original problem? What is the board's revision number?
If it is rev.1.4 and the components are unsoldered/missing, then you were indeed ripped off.

Yeah mines the same revision to the picture you attached. (ME571K_MB Rev 1.4)
The problem was that my nexus was charging really slowly but i didn't really put much attention to it. Then one day while charging my nexus i accidentally dropped it and the charging port went loose so i sent it to a local repair shop to fix the port.
The repairman said the charging ic was also the problem. but then after a few days they still couldn't repair my tablet.
They returned it looking like a mess.
battery wires were a bit chipped off. (No problem here, i used a tester if it still has a connection to the board)
the charging port was soldered upside down.
copper pads covering the circuit was removed.
some of the plastic parts on the speaker looked melted probably due to the solder mishandling.
So is there still a solution to the missing chips?
BTW. Thanks for the reply.! :good:

The charging IC is probably gone if the port was soldered upside down and powered up. The missing components can not be identified because N7/13 circuit diagram is not available. A working, second-hand N7 motherboard can be purchased for $25 on eBay and it's the cheapest solution. Let us know how it goes....
:fingers-crossed:
Oh ... so it's really busted huh. Thanks for helping me out.
But buying another logic board isn't one of the options i have.
I guess that i'll have to sell it somewhere then.
Thanks again.!

Sell the daughterboard after you fix the port, it only has the touch IC and should be good. Those are worth quite a bit. So are the screens especially if you include the frame. Just selling those separately should be enough to get you a n7 2012 or even a 2013 if you get lucky.
