[Q] Captivate Won't Charge But Will Recognize PC Connection

Edit: It looks like this is a hardware issue and I'll likely try to get it replaced via insurance since I cannot revert to stock using Odin. It is impossible to revert without using Odin right? Thanks to all who read!
To start, I just want to state that I've searched and searched for answers/information on this (not just on XDA forums either) and I haven't found a similar issue - my sincere apologies if I missed it.
Quick "this post is way too long to read" Summary:
1. Phone will not charge
2. Phone will recognize PC connection via USB but with no functionality
3. PC will not recognize phone
4. All details on what I've done so far below
Friday 3/4/11 - I used a USB car charger (link below) to charge my Captivate with a USB cable known to be working (had worked on my Captivate before, works on my brother's Captivate). If you're asking why I used that charger... well I got it for free with my E-71. I'll never use it again. Anyway later that night I tried to charge my phone on my official AT&T A/C charger but nothing happened - the phone acted like no USB was inserted.

Sorry for the bootleg link, this certainly isn't spam but I'm not allowed to post links yet.
Since that date, my Captivate won't charge via AC power cord. My PC won't recognize it either, but here's the weird part - my phone recognizes when it's connected to the PC via USB. For example, I can connect the phone to the PC and it will state "USB connected" on the Android pull-down (top) menu. Since I have mass storage chosen as the default, it will give me the option to send or receive files from the PC from the same menu. However, if I attempt to actually take that option, the pop-up menu which allows you to mount your memory cards does not come up. In addition, if I have the phone in USB debugging mode and I connect to my PC, the phone recognizes that as well. The PC does not recognize the phone in any capacity, at any time. No matter what I've done so far it will not charge via A/C.
Background: I've had my phone for a little over 6 months now, I've been running Cognition 2.1.6 since about 3 weeks after I got it - before this problem I haven't done any modifications whatsoever since the first load of Cognition. My PC is Windows 7 Ultimate 64. To rule out a bunch of other things, I've tried to use multiple USB cords that are known to work with a different Captivate and my Captivate prior to this problem (3 to be exact), I've uninstalled and reinstalled all Samsung's drivers on Windows, and I actually reinstalled Cognition using the three button recovery mode. To further rule out external problems, I just put Serendipity on my brother's Captivate using the same USB cord and PC that I'm attempting to use with my phone. He had been using the exact same version of Cognition I was.
I of course tried to revert the phone to stock using ODIN in order to fix the problem. I attempted to use the two button method (hold volume keys and insert data cable from PC with Odin running) but of course since the USB is not working properly that didn't work. It's worth noting that the described method worked perfectly for my brother's Captivate to revert to stock in preparation for installing Serendipity. I attempted to manually unmount and remount my memory cards several times, change USB modes between mass storage, Kies, modem, etc - nothing seems to work. The phone seems to be completely normal except for this USB issue. One last thing that's strange is if the phone is powered off and I have the USB A/C charger plugged into it, I cannot turn it on. When I hold the power button a relatively small spinning circle comes up after a second or two near the top of the screen. It disappears when I release power. If I remove the USB cable and hit power again it powers up completely normally.
Because of all of the above, I'm 99% certain that the issue is with my phone (not from any other external source). My only uncertainty is whether this is a USB hardware issue or a software issue where the phone is trapped in some sort of limbo due to being in a quasi-data mode which is causing it not to charge via A/C power and causing the PC not to recognize it. Has anyone had an issue remotely like this? I've come to terms with the sinking feeling that this is a hardware issue and that the only option I'm going to have is for my phone to be accidentally run over by a car (in order to pay my $125 and get a "new" phone under AT&T insurance). If anyone has any suggestions I'll be more than happy to try, maybe we can get this thing fixed!
If you made it this far I'll just say thanks for reading my wall of text and thanks in advance for any advice you have.

Were you able to get this issue resolved? It just started happening to my Captivate earlier today, and I was hoping that a solution had been found.

I haven't been able to get it resolved, I actually just sort of gave up on it and went back to my old phone for now. I have insurance so I'm not totally screwed, but it's not that cool obviously.
Were you able to get anything resolved on your end? If so I'd love to hear how. The one good solution would be a package to restore to stock that you could run through update.zip on a memory card, that isn't available yet is it?

i have this issue as well. I flashed Cognition 4.4 and it ran just fine for a couple weeks and then it began not even recognizing the micro plugged into any power source or the samsung dock! debugging on or off, battery saver apps removed, all that. multiple reboots. nothing. it takes a spell of, if i'm lucky, recognizing it after i eff with it for a few minutes and flukes a decent charge but at night, it usually has a loop cycle charging effect. I can hear the "boop beep" charger plugged in sound over and over throughout the night.
i use the phone in my cars and everywhere with the same problem.
no resolution! HELP!!!

I came across the same problem with USB on ARMANI I9010 after installing Cognition5. The most unpleasant is that i have bought it abroad and there is no possibility to return it
Does any body found the solution?

[Q] HTC One M7 Problem

Hello there 1st of all id like to apologise for this post in case there is a solution to this problem already and i didnt saw i but ive came from a 12h search now on the whole internet and found nothing.
-So the problem started quite simple my phone wouldnt charge when plugged in, i had Revolutionary Android HD 81.0 that time, so i decided maybe an upgrade to the newest version of the ROM would help so i downloaded and installed 82.0 version of it, still wouldnt charge, this moment i started to go freaky i was nearly out of battery and things were loking bad for me, i have my htc rooted, and it haves TWRP Recovery installed, ive wiped everything i could from there on it, os i have no OS now, my big problem started 12h ago, seems like my phone wont connect to the PC nor in fastboot, nor adb, doesnt even shows in device manager nothing, all i can only do is acess the bootloader and the TWRP on it, it charges tho now, but i need to get a rom on it and i simply cant, ive tryed all the Universal Drivers, and the newest HTC Ones even the Toolkit and nothing can detect my phone, tryed to clean up the mini USB port, Swiched cables , Swiched Ports, but nothing will detect it, since yesterday... when i deleted my ROM, im really desperate now since i cant seem to find a solution to this, any help please? any solution?

sounds like your USB port is broken ... theirs nothing you can do at this point until you fix the PC connection issue. Do you have a usb otg adapter to try and flash a rom from ? look on Amazon for a USB OTG Flash drive.

well that's how everything that's broken is .. it worked fine yesterday is nothing new. The USB port has 5 connections in it and the USB Port sometimes uses a thin flat cable to connect to the motherboard of the phone. So If the port on the PC works and the Cable is new / known good works on everything but your phone. that only leaves the phone port and internal connection.
Your problem began as not charging and then to no PC connection. The USB OTG will use the same pins the cable does and then you'll know if your port is gone or not

well the not charging problem had me shown um a few months ago aswell but dissapeared same day... thing is it was a software issue, since whenever it wuld stop charging it wuld go into "Car Mode" or Driving mode whatsoever its called, it wuld go in that mode alone and stop charging then exit and resume charging after few minutes, and its the same thing that started appening yesterday too, only this time i tryed to swich roms, and ive managed to get the 82.0 Revolutionary Android HD rom in there working but it wuldnt charge again, so i decided to wipe it completely via recovery, so now im left with recovery only on the phone, last time i got the rom via bluetooth since the PC connection wasnt set up yet, which was yesterday, but now i have no way of getting the ROM inside it, i mean its something wrong inside the phone, i dont believe the port is broken, but maybe some files corrupted? or something?

MTP mode vs camera mode?
Does kies recognize it?
Also as strange as it sounds, you may toggle developer options and usb debugging on and off. I did this on a family members ASUS tablet that displayed the same issue and then the PC recognized it. I was just trying everything I could think of.
Edit: I just realized you said Odin and not just connecting as a normally powered on device. Do you have it in download mode when connecting to the PC with Odin running?

unfortunately i cannot get the phone to bootup as to get into the hidden menu and turn on the MTP that way and yes if i am trying to connect to the phone to use odin i am in download mode when i try to connect.. the phone does not want to connect to the computer no matter what i do ive finally managed to get it to download mode and now am going to try and flash a different custom rom in the hopes it will boot up.. if it will do that i ill try and get mobile odin.. but even that hasnt been working. when i install a new rom and click on reboot the phone just shuts off. the phone wont turn back on after that unless i leave the battery out for several minutes then put the battery back in and press the power button. upon doing that the phone instantly boots to recovery.

This happened to me.
I even replaced the USB Port (Then dropped the phone while it didn't have the frame on and cracked the LCD)
The phone's USB port still didn't work and I had to replace the phone.
it is a very, very odd bug with this phone that multiple people have been experiencing but no one knows the cause of it.
It may just be faulty phone. Several people recently have had this bug.
my phone was made in Korea, Region: USA-Revision Q8R2.
N910T (UD)
So. Sadly, the only way as of right now to fix this is to get a new phone.
I tried a lot of things with my phone before I broke it to attempt to fix the USB port.
And the issue also lead to slow charging (220mA) and when I plugged it into the wall it would say USB Charger not AC Connected

Are you using the oem cord that came with the phone. I've experienced issues using non oem cords.

Yes sir I've tried multiple OEM and non OEM cords still won't recognize the phone

Did you try ask the different USB outlets? Did you try a different computer? For me USB 2 works, but not 3. Also I've had trouble with those on the front of the case. I always use the ones on the back. Just throwing a few things out there. It's possible you have a bad USB port on the device.

xiaomi red mi 4 cant connect to the pc

Hello,
First of all send a greeting to everyone since I am new to the forum.
I explain the problem to see if someone can help me.
I have a xiaomi redmi 4 (sorry if this is not thr prime, but I cant see the device in the list) with "fake" rom from the Chinese store. I know because the version ends in 0.0.
The problem is that when you connect the phone to the PC it does not do anything, it just charge (previously it worked well and the pc recognized it, also going out in the curtain the options to select load, mtp, etc.
I have tried several things and nothing works.
Probe activating usb debuging, with the app usb settings (which seems to open those options but quickly closes and the screen goes blank) and more different things but nothing worked, still only charging.
In the device manager it does not appear, neither as a connected device or as a connected device but without the drivers (I have the drivers well because before it worked correctly).
It all started when the battery stopped charging correctly, the battery charged very slowly. With the ampere app you can see that the charhe was very weak, no more than 100mah. Clean the usb port, probe with other cables and chargers, other pc but nothing to charge faster as usual.
Then I decided to restore the phone to factory but continued the same, charging very slow.
Later I decided to put a global rom using miflash with mode edl ( the bootloader is closed), but the phone never entered in that mode. Use the technique of power + vol + and vol- and I got it right. In the device manager I recognized it correctly (with the correct name that usually say in the guides for this type of operations), but miflash told me it was not connected.
Also use the adb commands (also recognized the mobile without problems, leaving the id of the device, but when using the abd reboot command, but the phone do not entering in edl mode, the phone restarted normarlly, even with some .bat that does the same thing also restarts in normal mode instead of edl.
For all of this operations the pc always detect the phone correctly, only the charge was extremely slow.
My surprise came when a few days ago I tried to remove the fake rom of the Chinese store and put the global, but the pc (mine and others more than probe) did not detect the phone, just charged me.
I think the problem is not physical, because if I plug in a mouse by otg, it works correctly, which makes me think that the data pins are going correctly.
I hope I have given all the detail that is needed in case someone can help me. If not, please tell me what else I can contribute.
Many thanks in advance to those who can help and greetings.
PD: sorry for my english

Moto G4 Play doesn't turn on disconnected from USB, can't boot into recovery bootloop

Today I was remembered of an issue I had already faced with my harpia, it's an weird state of bootloop in which even a full firmware flash won't solve anything.
If your harpia has the following simptoms:
1. Doesn't turn on, but you notice you can access the bootloader when it's connected to a USB cable(charging, with the other end either on a computer or on a socket)(If you only connect and don't press Power + Vol - it goes into bootloop again);
2. Bootloop (when connected) - doesn't even vibrate, only shows the Motorola boot logo for some seconds (sometimes a little bit longer for some reason) but then reloads it and keeps bootlooping;
3. You can access the bootloader (when connected via USB) and flash but it keeps bootlooping;
Then you might have the same issue I had!
One could think the problem is a faulty or old battery, but it's not - SOLUTION: Change the daughterboard.
Yes. Weird, right? I don't really know what it is but some problem with the daughterboard (the little second board that has the USB port, also called 'charging board' I guess(?)) causes harpia to bootloop.
I also noticed that harpia doesn't boot at all without one of those, at least my model (XT1603.)
I'm posting this here because I saw some old posts on lenovo's forums which had the same symptoms as I found in my harpia but didn't get any help from Lenovo, aside from the good old "send it to a repair shop".
Hope it helped!

A few times I made the experience that also the USB cable could be "faulty". You can charge the phone with this cable. But you can't establish a working data connection with this cable. Sometimes it looks like it works, but it doesn't really ... you have weird behaviour. With other phones this same cable works. Or vice-versa.
Therefore it is always a good idea to have many USB cables to switch ;-)
