Broken antenna and/or connector - Xiaomi Redmi Note 7 Questions & Answers

I was recently reassembling my Note 7 and managed to get the antenna and/or its connector (main, upper motherboard) twisted. Thanks to the quarantine I can't easily get another antenna, but even so there's the possibility that I also need to fix the connector. How can I do this? Do I need to solder it? Thanks.

Broken Display connector! help please :(

So I bought a new housing for my O2 XDA II Mini, during the removal of the display ribbon I broke the little black part on the display connector which holds the ribbon down, and after hours of trying to get the ribbon back in and secured I have bent the pins in the connector to buggery.
The ribbon appears to be untouched, however the connector which the display ribbon goes into is broken.
Is there anywhere I can get hold of one of these little connectors to replace my broken one, obviously very sensitive soldering will be needed to remove the old one and solder the new one in place.
Alternatively, does anyone know any mobile phone repair shops in Auckland, New Zealand who would be able to help out with my situation?
I fear all i'm going to hear back is "the motherboard needs to be replaced", however I am determined not to go through this route, as I am a poor student and the phone sounds as if it functions fine, makes the beepy noise when first starting up on the setup screen.
I was very careful with the actual screen unit while removing it, and I have had signs of life earlier on in the broken connector episode, however I can no longer get anything showing as I can't fit the cable in.
Cheers for any help.
Anything would be appreciated.
"obviously very sensitive soldering will be needed"
And that only can be done by machines/robots. I don't think humans are even able to sloder those kind of connections...
But, could you post a picture? cause I might have suggestions on how to fix it. One would be to bend back the pins on the tiny slot with a toothpick and when done to tape the flatcable, so it stays there.
I've maybe got a spare creen for you.

Loose Connector on Phone - Need help

Hi,
The connector on my touch (mini usb port) has somehow gotten loose or something. Everytime I connect the phone to charge or sync......the slightest touch/movement throws it off. I know there may not be much I can do right now except maybe replace the motherboard or something. Just needed some info if tht is indeed the way to go....or is there some other solution or a fix that any of the geniuses here can help me out with
Thanks in advance
Hi... apparently this does happen quite often with this connectors but it doesn't necessarely mean that that connector is overall loose.
Try to check if this might be your case.... On some devices I've noticed that the metal strips within the connector (in the phone, top part of the connector usually) looses away from its original position, if its not broken you may be able to unbend it and restore it to the original position with a thin pin or something of that sort. This will make things work again.
To prevent this from keep happening just be carefull when you plug/unplug your cables into it. Be gentle when inserting the cable and make sure to put the pressure to insert it only when its in the exact position.
hope this helps... good luck

I thought I had this problem, but it turned out to be a faulty USB cable - I think the wires were loose where they joined the connector. Since changing the cable I've had no problems.

Issue Replacing G1 Touch Digitizer

Hi.
Does anyone has been had this problem by replacing a digitizer to a G1:
I bought a newone digitizer for my HTC G1, after replace it and assamble it, the digitizer did workd at all. I retryed a lot of times and nothing. I test digitizer on another device and it worked fine. flex and cables were tested and all goods.
Any idea? any help?
Thanks.
Somebody having the same issue?
I have made that mistate before but if you know how to this this already just ignore what I say,
Check to make sure you connected the ribbons to the connectors correctly. There is a tiny little lever that is the lengh of the connector located behind the slot at which the ribbon inserts to.it should lift up and down, use your nails or a little toothpick. You must lift this lever to release the pressure on the ribbon cable in order to detach it. When re-attaching it, ensure that the lever is in the up position, then lock the little lever down after you insert the cable. Hope that helps. And remember be careful with the ribbons because if it rips just a little bit it wil cut the circuit.
Solved!!!

Connector Help

Hey Everyone, I've got a bit of a problem...
I replaced the glass/digitizer of my HD2, but in disassembly the screen connector broke halfway, and now produces lines across 1/4 of the screen.
Anyone have any idea how to fix this other than to order new parts? I'm looking for any ideas anyone may have to fix this!!!!
Due to me being a "new user", I can't post outside links, copy and paste to address bar.

You need to buy a new one again, you will not get a good repair unless you can micro solder, or cut ribbon cable short (at tear) and manage to reconnect with shortened ribbon (fiddly, but you may have enough good cable to do this).
Malex,
Thanks for the reply... I was hoping there could be a better fix than that...
It's not the ribbon that's bad, it's the flimsy plastic protector that has broken off

HD2 mobo radio prong issue

Hi guys, I had an old HD2 mo-bo that I want to resurrect, but one of the radio prongs fell off, causing very bad signal. I want to solder a tiny piece of cat5 wire from the pad of the broken prong to the one next to it (refer to pic). I would have done it already, but the connection pads on the antenna is separated.. I have two pics here to reference:

Is it ok if I bridge the contacts on the motherboard? I'm afraid that it would cause signal confusion.
Thanks in advance!
I would find something suitable to shape & solder to motherboard that will act same as spring contact that missing ...
