I was doing a screen replacement on a Nexus 5 and a small part from the motherboard fell off.
3 pictures to illustrate the problem here:
http://min.us/mKOC4FQe6F0HI
Afterwards, the mobile connection was a lot worse than before. Now, 2 weeks later, the phone's connection has become unusable and it constantly shows no service. Only very rarely does it have any sort of connection (Edge/3G/H/4G).
Questions:
1)What is the part that came off? (see album above) My knowledge is a bit limited but I'm quite sure it has to do with the connection? I notice there are 3 other parts exactly like this spread over the motherboard.
2)Can I repair it? Do I glue it back on? Do I solder it on? Does it somehow click on? (I have tried if it clicks but this part is so tiny it's almost impossible to really handle
3)Based on my explanation, do you think this tiny part is the only cause? The phone still had some connection at first but it got worse. I'm also planning to order replacement antenna cables to see if that helps.
Thanks in advance!

In my case.. I had to replace the charging circuit Cuz it was 'broken' as described by the cellphone shop.. It has connections to the antenna.. Now phone is fully working.. Before that though, I tried different sim cards with different companies (bell Rogers and fido) all worked on my phone except my carrier sim card (mobilicity). After replacing the circuit I just mentioned everything works fine. Cost is 25$
Needs solder it's an rf trimmer /radio frequency. It's vital to an ariel of one type or other. If you want to risk a bodge assemble everything except the back and hold it in place with bluetack. If it works I was going to say epoxy it but don't. Get someone to solder it. It's easy to do if you have the skills.
Oh vital it's right way round and has now been turned. There should be a slot for tuning it.

Hi folks my other half who has a C600 has complained about joystick issues for a while now so I finally did something about it (sick of her complaining about her 'crap phone' - ungrateful #!&@! ), not sure if this is THE issue with the c600 joystick so would be interested in any feedback good or bad.
Basically the joystick became less and less responsive over time so harder presses were necessary to perform actions. Didn't fancy spraying WD40 in my phone (what does this actually do?) and after testing switch operation with my meter all seemed ok.
What I noticed was that the piece of metal holding the joystick is stamped to a lower level than the rest of the metal chassis holding the keyboard. This section is only supported at one end and therefore, every time the joystick is moved a bending action is exerted on this 'sub chassis'. Hopefully this picture might help people understand what I am on about...

Now I found that by simply bending this piece of metal back up a little bit I restored the joystick to it's former self! No cleaning, NO WD40!
Now just to note I didn't mess around but I suspect the problem might return in time so maybe these phones are missing a bit of support between the joystick chassis and main board? Maybe someone messing about might want to investigate sorting this.
Hope this is useful to someone although I realise it is coming a little late in the C600 lifetime!
I just thought on if I get enough requests I could do a decent photo guide for stripping the C600 and maybe the VOX too.
What I do is clean all the dust out of the rubber piece that's over the joystick in my T-mobile SDA, and then spray the joystick with quick dry electrical cleaner (usually available at your local car parts store).
Hi thecraze, yes being an electronics engineer I am aware of switch cleaner. I realise in my case however this was not the issue, as all switch contacts showed a good low resistance with little effort on the joystick. There was also negligible dust too.
I have also noted that cleaning does not work for everyone, and this may be one of, if not the contributing factor in such cases.
Thanks anyway.
Will I need different shaped screwdrivers or will a regular (small sized) Phillips & or flat head screwdrivers be all I need?
While I was looking for screens on eBay and Amazon I saw some that came with tools. One of the screwdrivers that came with one of the screens looks like a star so now I'm wondering if there are any star shaped screws holding the screen down that'll need a star shaped screwdriver to open it with.

I hope replacing this screen doesn't end up becoming a huge pain. Will I be okay buying just a screen for $5 or should I pay almost 3 times as much to get the tools?
This is the screen I was originally looking at for $5.55 http://pages.ebay.com/link/?nav=item.view&id=110787423167
Thanks for your suggestions!
When I got a new flex cable it came with the tools needed. BUT I found that a screwdriver I bought from radio Shack had better fitting tips. I'll try to find a link later today if I can.
Edit: I think what I'm referring to is called; RadioShack® 21-Piece Precision Electronic Driver SetCatalog #: 64-185 *|* Model: 6400185 for $17.49
This should be in Q/A. But that being said. I would spring for the kit that comes with the Tools. Especially if you do not have the correct tools. Yes you are going to need the Star shaped Screwdriver. Not for the Screen itself, but to be able to get to it. Also a few other suggestions. One make sure you watch the Video linked in THIS thread on how to disassemble the Shift. That thread also has pics you should study a bit. Another thing that I cannot stress enough. HAVE A CLEAN WORK AREA TO DO THE REPAIR. It will save you a bunch of headaches. Take your time. Do not try to rush the procedure. Lastly, make sure that the work surface, and you are properly grounded. This will avoid any issues from static discharge. Read, and take your time. It will save you grief later on .
Hi everyone,
I recently got my watch
So far I can tell you that I got the first (i think) OTA dump for Android Wear 2.0
https://drive.google.com/file/d/1fFN4woS7a6jEioeYaG76USHRzDQFk6HF/view
The Sim can be replaced, not easy as you can think but it can!

If someone has a broken one, I could do replacement video for sure. I didn't find any USB connection that could be used in the recoverymode...
There is a group working on a USB connector with the Band pins over here:

Click to expand...
Click to collapse
Here's an idea,
So we know which pins are required to interact via USB and can now install TWRP on it. The problem with this is that in order to use USB, we have to take apart the watch and fancy a connector out of wires and such. From what I read, contained in the band is a LTE antenna connected over 4 pins (and I believe a Wifi antenna in the other), since we dont need LTE (at least where I'm at in Canada), perhaps routing the 4 pins (and de-soldering them from the motherboard somehow) to the USB pins on the motherboard could make a much cleaner way to connect usb. this would require quite a bit of fine soldering, but if you're up for the task im sure the old LTE band can be hacked apart to fancy a USB plug out of making USB access alot easier. Could help with development forsure. I havent received my watch yet but I think this would make a decent mod.
got this verizon wear24 watch die on me - touchscreen sensor isnt registering any touches. any suggestions to revive it?
I think I bought a clunker of a deck, MTCE / GS in nature.
However, it's complete lack of buttons, SD slots, etc has made rooting to improve it, difficult.
Has anyone had experience with ISUDAR decks? Are there any procedures that can help me get root / xposed onto the stock firmware, so I can fix the UI to add volume control etc?

Finally I've found another ISUDAR owner to compare notes with! I have the exact same model you show except the slightly older 7.1.2 PX3 version with 2Gb. I've had decent success with it except Bluetooth problems using OBD and somewhat flaky success with a 10Hz Bluetooth GPS unit, but always works great with my S7 phone. Other than that works pretty well. I also have plans to sort out a physical knob solution, possibly with Arduino.
Support hasn't been great, but probably typical. The seller finally sent me updated ROM .rar and .zip files yesterday, but gave instructions how to flash using a SD card in the GPS slot.... Obviously there isn't one, so I'm waiting to hear back how they want me to do it.
I found a button inside the small hole on the lower right side of the face plate. Stick a paper clip in there. Short press is mute, medium press will turn the unit off, long press I think will actually reboot. There may be a further press sequence to enter recovery? (To avoid the paperclip route, I made my own button from the head of a small nail leaving only a few mm of the stem. Take the face plate off and insert the nail from the back, this way it's captured once you put the plate back on, the head presses on the soft button inside and the nub sticks out the hole. Seems appropriate quality solution :laugh: )
What car are you putting this in, I assume 2005-2008 Porsche?
Hello, I would like to present my solution to the no service problem.
Some two weeks ago "no service"show on my phone, I tried many ways to solve the problem:
-I tried different sim cards
-I changed my ROM with LGUP
-I make ROOT on the phone
-I change modem file
-I change modem options i Hidden menu
Nothing helped !!!But today I restored the phone(H990DS) to life and I would like to share my solution.
First of all, the symptoms my phone has had:
-No service
-signal strength 0dbm 99asu
-inpossible RAT in hidden menu and network mode
-impossible to change BAND in hidden menu
My solution
In my case, the problem turned out to be hardware, although I thought it was a software
First, we take out both covers with antennas . We unscrew four screws from each cover and pull them by pulling or slightly undermining.

}
at this point, when I switched on the phone without covers / antennas, this one tried to go to the network and I could choose RAT and mobile network.
Tthere was a lot of dust and other **** under the covers!
I cleaned everything nicely with a brush. Then I cleaned all the marked pins on the phone and in the covers with alcohol.
Using a small flat screwdriver, I slightly raised the pins on the motherboard for a better contact.
Later I turned everything back and my phone is working properly
I think that the muck caused resistance and the modem turns off the transmitter so as not to damage it. I hope my solution will help someone, sorry for my English.
Same Problem
I've the same exact problem with the same model. The pictures in your post are not visible. May you please, re-upload the pictures or send them by email?
My phone is a brick
I found a few old photos on google drive.
After pulling the battery cover, you can see 8 screws from the plastic covers / antennas. You unscrew the screws and pull the covers until they come off. You can undermine them, it's easier to go down but there is a risk of damaging something. I do not have v20 anymore, in my case the way I described helped about 2 months. After this period the problem occurred again and helped replacing the motherboard ordered in China (the new motherboard had a problem with the zyroskop ). I hope you will have more luck, it was a very good phone if it was not for defects.
