Axon 7 Repair - ZTE Axon 7 Questions & Answers

I dropped my Axon 7. Though there's no visible damage, the phone will frequently freeze (not turn off) and just continue to display whatever was on the screen at the time. Or the the charging LED will remain on if it was just charging and not actually booted, even if I unplug the phone.
I opened it up and reconnected all the cables, but no luck.
Once it starts, if left gently on a table it will continue to run, but if I jostle it it will likely freeze.
I've been experimenting and know I get the same behavior if the phone is running on AC with the battery disconnected (I think that worked...) , or if I run unplugged with the battery.
Any ideas? Since I already have the phone open and don't much have to loose, I'm willing to attempt more surgery, but I'm not sure how to diagnose the fault. (Yes, past the 2 year damage warranty).
Happy for your thoughts and suggestions!

There was a post on here with the exact same scenario, if I remember correctly it was a cable to the screen/display.
I've dropped phones and sometimes the pins bend slightly so check the connection pins.
I even repaired one that fell into a bowl of milk

found something?

Ok - What do you think about this? I can't tell if this is superficial. ($20 USB microscope I bought for my kids rocks)

Assuming this is the issue, does replacing this cable mean removing the screen? I've heard that's hard...

I can't see from the pic properly but it is possible, the only way to know for sure is to compare with an original condition unit. (Looks better than some I've seen)
I was fortunate enough to have the same phone as a backup so I could check in my case.
Just make sure all connectors are snapped into place and no broken fragments in the connection.
I hope you get it sorted

That's in the outermost part, it will surely not cause anything at all...

I was afraid of that. Back to the drawing board... or just wait for good Black Friday deals.

Hermes battery door release button problem - info/image request

The battery door on my vario II won't come off when I use the release button. Can't remember ever noticing how the clasp/mechanism worked, could somebody either describe it or take some photos so I can see how to remove the back door without doing any more damage?
Thanks
James
Is the vario II door the same as the TyTn door ? I can't remember, if it is I can describe and get a picture within half to 1 bour.

Thank you! Though it doesn't look very good for finding a way to release the door without damaging it. Does it look possible to you?

No it does not look easy. Does the little catch still slide back and forth easily on its spring?
Mike
yes it does.

This I think is bad news cos looking at the one I've got the back off at the moment, if the catch just slips out of engaging the white sliding catch mechanism then it gets really stiff. BUT there is a tiny prong on the black sliding catch that engages the white sliding catches!! (Sounds like this may have broken off, allowing catch to move freely because it's not engaging with anything.)
1. If it's under warranty I'd take it back and have a battle about whether you were "rough" or not, or whether their catch is crap.
2. You could prize up back cover. Not a good idea I think the back cover prongs will snap off.
3. Just dont't take back off!!
4. I think it may just be possible to remove the one screw (Torx) you can access with the cover on. Prize open the case just a fraction to allow a pin/needle to be used to slide the catch and release back. With the device face down you would need to pass the pin through above the central part of the catch and move the pin from right to left. You could in theory wthen completely remove the back housing and examine the catch.
Mike
hmm...well had a brain wave and gave the phone a bit of shake. Something inside definately rattles! On closer inspection it also appears as if half the clasp is working - moving the release switch makes the door move a tiny amount.
So it looks like i'll be going into t-mobile and seeing what they say!
Thanks for the help (I may need more if i can't get it replaced!)
Solution and slight embarrassment...
So, nothing was actually wrong as such!
I had been finding that my battery was getting hotter than I was happy with, so I had removed the sticker from the front of it to allow the heat to dissapate more efficiently. This had left a sticky residue on the battery which had stuck to the battery door.
So that's me feeling a bit stupid!
Just pleased it's problem solved - good news

Fix for Sleep Of Death!

Did your tablet screen go out? Does the backlight still come on, but the screen shows nothing? Can you hook it up to a TV, and the picture comes out fine? If so, it is most likely a loose cable, and can quickly be fixed by you, without RMAing it and waiting weeks or months. While the guide should be spot on, and you aren't going to be harming the device in any way, I'm still not assuming any responsibility if you destroy your tablet. You will first need to take apart your transformer. There are plenty of guides out there, so once you get the back off, come back here!

Hi stuntdouble,
Two torx screws have to come off first, these are part of what holds the bezel down.
After that you need to use a guitar pick from the back to lift the bezel up...best to get all 4 corners up and keep sliding..as soon as it wont slide lift it out and back in again a bit further on... it absolutely destroyed the pick by the way..lots of sharp edges in there.
The bezel will then come off from the front of the tablet. Just be careful and dont force it, Around the 40 pin connector was the biggest pain.
The back cover is held down by 4 screws on the top glass, and umm if I recall about 10 screws behind where the bezel . It basically then falls off once all screws are off with not to much effort.
There are also no security stickers over any of the screws anywhere inside the tablet

Take a look at the bottom, you should see a strip with a bunch of multicolored wires coming from the battery. Underneath it, and near the bottom of the battery you should see a ribbon cable. Here's a picture, the display cable has a flashlight shining on it.

Try pushing that into the slot a bit and see if that fixed it. If not try pushing on a few of the other cables, if this doesn't fix it, then I would suggest you RMA it, although I really think this will fix it for you. This has happened twice to me, and each time, pushing cables a bit seems to do the job.
Best of luck on fixing it and post your results please!

[GUIDE] Nexus 7 Motherboard Pin Repair (WiFi, Bluetooth, NFC)

I've had my 32GB Nexus 7 2012 (grouper) since it was released. I love it, or well, I did. Until about 12 months ago, the WiFi reception and speed plummeted into what may as well be hell in the stone ages. I couldn't find the problem. I thought it was something to do with software, as I had recently upgraded to a newer version of Android at the time. So, I dismissed it, and waited patiently for a fix. Nothing. So, it has been sitting there since KitKat was released, doing nothing.
Until now that is! I decided that I didn't want to look at it doing nothing anymore, so I researched far past page 2 of Google (Desperate times people, desperate times...) and I found this gem!
I strongly recommend you DO NOT perform that guide. It can damage your device even more. Instead, please use the guide below:
YOU WILL NEED:
Small knife or Electronics opening tool
Soldering Iron (Sorry)
Solder
Basic soldering skills
[URL="http://rover.ebay.com/rover/0/e11400.m1842.l5919/7?euid=f15f56b658ee4efebf0c8f34c466567e&loc=http%3A%2F%2Fpayments.ebay.co.uk%2Fws%2FeBayISAPI.dll%3FViewPaymentStatus%26transId%3D472422032026%26itemId%3D390820734137%26qu%3D1%26ssPageName%3DADME%3AL%3AOC%3AGB%3A5919&exe=11193&ext=27012&sojTags=exe=exe,ext=ext]Contact Fingers (As many that are broken on your device)[/URL]
Right, lets get started...
(Oh yeah, and to make sure you can't sue me if you mess up, I am not liable for any damage you cause to you or the device you're performing this guide on. This may also void the warranty on the device you are performing this guide on)
BEFORE YOU BEGIN!!!
Turn off your device
Ensure that your device is unplugged from any power source
1) Open the Nexus 7 carefully.
2) Find the broken contact(s). The red circle in the picture below annotates where one of the WiFi contacts is broken.

}
3) Put the replacement contact finger(s) in place
4) Solder the new contact(s) onto the motherboard ensuring that the solder is only touching that contact
It's important that the solder is only touching one piece of metal, as otherwise the circuit will be shorted and your device may be damaged.
If you have messed up the soldering, there are tools to remove the solder, or you can re-heat it and try to wipe/scrape it off. The tool you want heats up, and sucks up the solder off the circuit board.
5) Leave the device for at least five minutes
6) Once you have left the device, check to see if the angle of the new contact is the same as the other ones. If not, gently bend it into place.
7) Place the casing back onto the Nexus 7, and press to lock it into place
8) Boot up your device
And that's it, you're done!!!! If this guide helped you, press thanks, and if you're feeling generous, donate

Broken Link
Hi,
The link you have provided is no longer valid, I just thought that I would see what I could find and this is one of them:
hypertext protocol:worldwidewebdotdigikeydotcom/en/product-highlightslashwslashwurth-electronicsslashwe-secf-emi-contact-fingers
I can not be sure which one to choose. I see one very similar to what my N7 has just not 100% certain that it would be correct one and or fit.
Regards,

how does this apply to NFC? my NFC is not working and i opened the case, saw one pin was bended (NFC section PIN), tried to put it back up and it broke. You think that by fixing the pin will it work again?

Why not? If that was the reason and you rectify it, it should work.

Help identifying components on Nexus 6Pmain board

I'm wondering if anyone can identify the two components circled in red in the lower right corner of this image?

I recently replaced the screen on my Nexus 6P, but these two component came loose (likely from when I took off the screen connector below them). One of them was lost as well.
After replacing the screen everything seems to work ok except that the Sim card is not detected. (The same sim works in other phones.) I'm suspecting that these two components are the issue. It's pretty likely that I would not be able to successfully replace them, but then again it might be worth trying.
Any thoughts? Thanks!
Your image link don't work..
But btw, why did you replace it? Broken?
I hear it's a very difficult and risky process to replace screens on 6P..

I just updated the image in the original post. I think it should show up now.
I dropped the phone from about two feet up and the touch screen quit working. Replacing the screen was a bit daunting, but actually seemed to go quite well until I figured out the sim was not recognized any more. It was a bit tough to pry off the camera shield on the back and to pry the insides from the body the first time. But now I can do it without too much trouble.
I think that the two parts I wan to identify might have been a bit damaged before (water damage?), and then I might have inadvertently helped them along.

I can't see your image for some reason either on Tapatalk but I can in web view. Check ifixit for a full outlook of internal parts:

Edit: On second thought, the piece you're asking about wouldn't be discussed by them.

That's gonna be tough with no markings on the board or components. Google "identify smd components" might yield some helpful results. I think they are either smd resistors or fuses. As a last resort bridge the connections individually with solder or conductive glue. Check with multimeter after you bridge them to insure no resistance (good connection). Really looks more like those are components for the display circuit though.
normally those are some resistor smd.
you can check on other phones (service manuals) what kind of component is there.
i saw a service manual for lg g3 here on xda, you can check whatever you want but try to search for a component like that.

Nexus 6 Main flex?

So. I have a nexus 6 device and i sent it with a technician for a battery swap (turning of randomly). The thing is when i got it back the phone was dead, the device didn't show any sing of life (didn't boot and didn't even showed a charging animation.), i tought the new battery was the problem but the technician told me that wasnt it. I didn't receive any explanation of what happened to the device or why it didn't turn on.
Anyway. I oppened the device myself and realized that a flex was partly sliced. (the flex conected to the other flex that's supposed to be for the buttons).
