Little to no signal after changing out fried charger port. - T-Mobile Samsung Galaxy S 4

My phone's charger port was recently fried when my phone got stuck in a boot loop over night while charging. I bought a new board and replaced it but now I have no service. I occasionally get full LTE reception but do not have mobile data at all. Is it possible that the blue cable, which I have seen referred to as the WIFI Flex Cable, is causing the problem? The M919 has the one blue cable, but the other variants have two cables that connect to this board. Anyone have any idea about this? Any help would be appreciated.

Where did you get the USB flex cable? It could be the flex cable that is the problem. I have read other posts where people replaced their phone's flex cable which resulted in network signal, charging, data transfer, or wifi problems.

I didn't change it out. I used the same one that was connected to the previous board. I just bought one and am going to replace it to see if that fixes it. That's my last hope before I have to buy a new phone so here's hoping.

Loose Micro HDMI Cable

I ordered an Amzer Micro HDMI cable for my Evo a few days ago, and it works and all, but if the cable wiggles around a little bit, it disconnects and reconnects shortly after. The cable does feel very loose in the port (much looser than the MicroUSB cables feel in the charge connector).
Has anyone else had this problem with their Evo, or has anyone found a solution (like a different brand of HDMI cable that works better)?
I ordered the same one last week. No word on when it will ship though. I'll let you know if my cable is loose when I get it.
I am having the same problem with the Amzer HDMI cable. I would have to push the cable downwards in order to get the video to play. If I wiggled it or pushed it up, the picture would be lost. I will replace it once I get fed up with the cable.
I don't know about the amazon cable, but I did order the HDMI cable from the same guy who sold the two batteries and wall charger for 10 bucks on eBay. When I played around with the cable it did feel loose. But when I forced the plug into the phone it went in further and made a solid connection.
Don't know if that will work for you guys too
I had this issue with my OEM micro-usb. I bought 6 more USB cables ranging from 3ft - 10ft... they work fine now. Check the actual cable to see if the pins move around, that may be the issue... aka poor construction

I have exactly the same issue with the cable I got from Monoprice. I couldn't hold the phone and move it around as it would intermittently disconnect. But if I set the phone down the connection stayed throughout.
Before you guys get all up in arms I have the "official" HDMI cable from Sprint and it is loose too. Its the socket not the cable. I'm on my second EVO and they were both the same way, loose.
anyone else have this problem? I have the monoprice cable and the connection is flaky. My EVO is only 2 weeks old.
Same thing here with monoprice cables. It isn't 100% the socket though, as my buddy's cable works perfectly fine in my evo. Don't know where he got his, but will find out.

[Q] Question new unlocked GSM, USB charging issue

Ok so i ordered my new phone directly from google on tues and i got my phone thursday. I am having some issues with different micro usb cables not connecting and charging it. I know that some of my other cables work with the phone and some dont. Is there something wrong with my phone or did samsung ever so slightly change the cable to make it proprietary? Also the speaker is really weak are there any mods for it or just flashing a different rom is the only way to improve it. thanks for any help guys

Any microUSB cable should work with this phone (I sometimes use my cable from a Huawei phone) - Samsung hasn't done anything to make it proprietary in any way.. How well do these other cables work with other microUSB devices? What exactly happens when you try to use these other cables (e.g. partial connectivity, no connectivity, etc.)

Microusb cord falls out of port

Hello everyone,
This is my 2nd note II. My first device had a few problems and now this one seems to have a loose charger port. Also, when I connect this device to my tv via microusb, the tv screen flickers (could be an indicator of a faulty micro usb port). Has anyone had the problem of their charger wire falling out of the microusb port? What did you do to fix it? If you sent it to samsung did they return the device in working condition without any dings or scratches?
Thanks im adv

Mine was perfect for the first few weeks, but eventually got a bit loose so I replaced the USB cable which did the trick. Ive heard of other cases where the usb ports became loose, but not to the point of it falling off on its own.
Have you tried other USB cables on your phone?

hey i did try the usb wire that came with my samsung media dock... its a bit more snug, but it came off randomly after a while. my samsung otg usb cable fits great... the thing that concerns me is that sometimes when i connect my device to my media dock (uses the microusb port) which connects my phone to my tv, the screen on the tv flickers. this could be an indication of a faulty microusb port... but heres the confusing thing, ive tried transferring files to and from my computer via microusb and it works fine, so that would be an indication of a working usb port.
from what you have heard or read, was the consensus a problem with the usb port or the wire?
thanks
Yes, the wire was the culprit based on my reading.
Better have your phone checked. Im sure it's well within Samsung's warranty period
Ironically the best cable i use is a blackberry one, excellent secure fit

Problems with USB connection

I had been somewhat unlucky and while charging my beloved FLO something went puf (literally). After that I don't have any USB connectivity. Charging my N7 works (very slowly), but no USB OTG or USB ADB. OK Fine and dandy if I wouldn't be total idiot and wipe system while trying to install new ROM before transferring ROM image to internal storage.
Now I have FLO paper clip able to go to TWRP but can't install nothing. As far I understand there's no way to enable wifi in TWRP.
Any ideas what would needed to be replaced to make my FLO work again so I can put some ROM on it and make it work again.
I'm not sure if USB daughter board would suffice and solve my problem. Any suggestions?

Either the USB port developed "dry joints" or the wide silver cable (LCM) needs to be re-seated on both connectors.
Disconnect the battery before fixing LCM cable. Here is advice on USB port repair.
Replacing the daughterboard PCB should be the last resort because it is unlikely that the touch function will work 100%. It would work if we had access to the touch calibration software - the problems are described here https://forum.xda-developers.com/ne...rivers-to-calibrate-touch-screen-usb-t3334898

I doubt re-seating would help or cleaning USB port, since it was something electrical happening with that *puf*. If my memory serves me right there was a smell of burnt electronics. I doubt that some shortage disconnected any cables.

Sounds like you need a new charging port and board. Easy to fit but difficult to get hold of one. Maybe purchase a broken Flo on eBay and extract the charging port board

Even tho charging works? The only problem is data part of USB connection. USB OTG will not work neither will it connect to a PC for file transfer/adb. But if connected to PC or plug device charges. I believe it will not charge past 80 or 90%.

Problems with USB-C connector?

I noticed that when I connect the phone via an USB-C cable to my computer or to an USB stick, the connector only works in one direction, like in the old USB-B days. When I rotate the plug it no longer works reliable.
Haven't faced such an issue. You should try another cable and if the issue is persistent, maybe the USB connector itself is having issues and you should reach out to Nokia service.
I tried several cables and eventually got in contact with retailer and received a new device. On the night before the new device arrived, I couldn't really charge the phone. Hopefully this won't happening again.
