[Q] USB issues - not charging - can't get into fastboot mode

Hello everyone,
having major USB issues on my GNex. It's not charging anymore, but when the phone is off, it displays a charging animation. I could get it to charge once since this occurred, I left it plugged in overnight on my Mac (phone turned off). Did the same thing last night, no charge at all.
Mac OSX does not recognize the device, my Windows machine keeps telling me something like "the connected device is not working properly and can't be used... ". This message pops up every few seconds, so I guess it's constantly connecting and disconnecting. I can't access the internal storage on both systems.
My first guess was a hardware defect. But when I try to boot into recovery mode, a screen instantly pops up that shows Andy and displays a message: "Downloading. Do not turn off target.". In the upper left corner it displays " ODIN MODE" in small red letters.
When I press the power button in this screen (there is a big arrow pointing to the button with "start" written in it) the phone just normally reboots.
I can't get into fastboot mode because of this. I can get into CWM Recovery when i use the reboot into recovery option built in the ROM.
I dunno much about Odin (next to nothing). Has it something to do with Samsungs Kies? Could it be that something has put my phone in this "ODIN MODE" and it constantly tries to download something, making the USB port unusable? The port is not completely broken, as the phone displays a charging animation when it's turned off... so there is some connectivity left!
Thoughts coming up that this could be some kind of software issue. If there is a possibility to get out of the Odin Mode, it may solve the problem.
The phone is unlocked and rooted, running AOKP Milestone 5 and franco kernel.
I tried to restore an older nandroid, but it did not change anything.
Would send it in for exchange, but not able to relock the bootloader due to no fastboot access. If it can be confirmed that this is a hardware problem, I have to pay for the repair, I'm fine with that.
Has anybody any ideas that could be helpful? Any help is much appreciated, thank you in advance!

Do a search and you will find at least 30 helpful threads. Basically you only need to replace your USB charging board and it works again. Should be a warranty issue, but Samsung has really been an ass on handling this issue lately and claiming water damage.

I have mentioned it many times here: this problem can be probably solved by thoroughly cleaning your USB with soft toothbrush.

True, I also cleaned my port but it only fixed it temporarily.

Thanks guys. Tried to clean the port, nothing changed.
Ordered an OEM charging board off ebay, hope changing it will fix the issue.
Only thing I'm wondering about is, that the phone is stuck in Odin Mode when I boot it up with Vol. - and the Power Switch. So I downloaded Odin but it does not recognize the phone...

I am also facing the same problem. I am currently using the phone by charging the battery externally. Can someone confirm that changing the USB flex cable is the solution ?

Just posted in another thread but it is definitely the USB port for me. Using an HTC Vision (Google g2)

[Q] s4 shuts down seconds after powering on

I left my perfectly fine i-9505 s4 to charge overnight to find out it did not respond to anything, holding down the power button or power+voldown+home did not result in any sound image or vibration.
Removing the battery and re-inserting it makes the s4 respond to the power button, but the phone shuts down seconds after powering on. This also happens when I try to enter recovery, download mode or insert the charger.
It even happens when I use my usb JIG, the downloading screen appears for a second, after that the screen blacks out again. Tried removing the SD / SIM cards.
The only way I can connect it to Odin for a second (at least as far as I know), is by:
1) removing battery,
2) inserting Jtag
3) inserting battery
4) remove JIG (very quickly)
5) insert USB to PC (very quickly)
Yay! Windows makes the "USB connection" sound, before making the "USB connection lost" sound a second later and the screen blacking out..
What could cause this? Is it my battery? Connector? Software (jamals 4.4v6, faux123, mj5 modem)?

Have you tried directly plugging it into the charger or your computer without the battery?

Thanks for your reply.
Yes, I did try that, the screen does not turn on if I plug my charger / USB cable from PC into my S4 when the battery is removed.
What could cause shutdowns after 2 seconds from booting? I hope this is fixable!

It sounds like there is a physical defect in the device. If it was software related (this can be caused by a borked up ROM or Kernel) you wouldn't see the same behaivor in Download mode and that doesnt' use either the ROM or Kernel.
You could have something physically broken inside the unit that is causing an electrical short once something common to the system and download mode is activated, which would cause the reboot. That could be the USB port that both the system and Download mode will constantly poll the USB port looking for a connection, but only after a second or two. It won't look at the USB port immediately when teh GALAXY S4 splash screen pops up so that's why you get a second of it working. There are 100 other things internally that it could be too.
I'd say make sure the charing port is cleared of any debris. If that doesn't work, I'd say it's broken and needs to be repaired. Without knowing exactly what is causing the issue I wouldn't suggest trying to fix it because you'll cancel the warrenty by doign so and might not find the problem. It could even be a faulty memory chip on teh circuit board that wouldn't look broken to the eye.
Since you can use Download mode for more than a second, you obviously can't try to restore to stock, which is the prefered go to method to fix things like this.

Sounds very much like a hardware malfunction. Without having the device on hand, I can be of no help, unfortunately. If it's under warranty, I suggest you try to get a replacement.

Thanks for the replies. You have convinced me that this is a hardware issue. I have no clue as to what might have caused this defect.
I will soon try a different battery, and if that fails I will contact Samsung.
Unfortunately though, my firmware is custom and this may void warranty, which would suck since the cause of the issue is probably not related to the software.

A day later, the problem appears to have solved itself. I'll keep you updated.

My S4 was working for some time, but the problem returned, the phone shuts down seconds after booting (normal boot / recovery / download mode / USB-Jig induced download mode..)
HOWEVER:
Sometimes, when I connect my S4 to a charger, it turns itself on (first displaying the charging icon) and then starts booting, showing the Google boot animation (since I'm running GPE). This animation keeps going for minutes, and then the phone shuts down again (black screen, does not respond to anything.

You're just delaying the (possibly inevitable) death of your phone. Use your warranty while you still have it. At least I would in your situation.

The symptoms that you have described are those of a bad power button. This happens quite often.

I think you are right! It would explain the inconsistency and the fact that my phone sometimes turned on by itself.
Thanks!

I had to send my S4 back to Samsung THREE TIMES before they realised it was a hardware error. The first two times, all I got was a factory reset.. Which of course, didn't help.
I'm pretty sure you were right, it was a bad power button.

[Q] Battery doesn't seem to charge, can't get into Odin

I have a Samsung Galaxy S2 Epic Touch for Virgin Mobile I'm selling to a friend of mine. It's been working great for me for about the last year on VM. It was rooted and running Liquid Smooth and then CM 10.1 (both using CWM). When I called VM to transfer the phone to my friends account we ran into a road block because CM doesn't respond to the keypad phone codes VM uses to update the phone, or have the VM hands free activation apps.
I figured I might as well flash back to stock ROM anyway. I downloaded the ROM from here.
Odin got about 75% of the way through the flash and then failed. The phone won't turn off but instead keeps up a persistent splash screen asking me to connect the phone to Kies to do a system recovery (Which I did try and Kies can't seem to complete the connection. It sees the phone but can't connect to it, even after ensuring all drivers are up to date. But then I've never had much success with Kies).
I can still get into Odin on my phone so I tried downloading the .exe ROM instead of the md5 this time, but by the time the ROM downloaded Odin tells me the battery is too low to flash anything (which I believe). Problem is I can turn the phone off to let it charge properly (it pops up with the Kies message whenever I plug the phone in).
I've left the phone plugged into the wall hoping that maybe it is in fact charging, but the indicator light only flashes for a second when I plug it in. I'm working a double shift today so I left the phone at home hoping it will charge so that I can try flashing again, but does anybody have any experience with this sort of problem, or know if the phone will in fact charge?

The easy options are to borrow a battery from a friend with a s2 phone, or get a charger off ebay, or buy a new battery from the store which will probably come with a partial charge.
Sounds like your usb port may have died. That happens sometimes.

I was thinking of borrowing a battery. I have a friend with the same phone, so that's possible.
If the USB charger failed, however, would the blue charging light still flicker on when first plugged in? Because that's what it does. It doesn't charge, but it does seem to acknowledge that it's been plugged in. Also, when plugged into the computer it will still flash the plug me into Kies screen, but now my computer doesn't seem to even recognize that anything is plugged in.

It is possible. I had a phone that the data burnt out on, but would still charge. Just one pin needs to be bad to cause some issues, but not break everything.
Could just be the battery is totally empty too. Getting a known good battery with a charge is the first step to troubleshoot this.

I have encountered this problem a time or two before when testing some of my many attempted multiwindow mods, the device will in fact charge, but it is going to take forever. After a double shift I would imagine you'd have enough charge to flash properly, so try it again afterwards. Also have you attempted to return to recovery? If Odin only partially completed, your custom recovery may still be there and you might be able to use the power off option from recovery, while the device is plugged in, and possibly tricking it into not powering on to the error screen.

Callin ODIN experts!! Enable/Disable USB Data in Odin Mode?

Hey guys,
Something really strange is going on with my USB port on my Note 4 Dev edition. All of a sudden USB stopped working, when connected to a PC, it would only charge, but no Data whatsoever. After trying to connect it to a bunch of different PCs, different cables, restoring to old nandroid, nothing worked. When plugging in the power cord when the phone was off, the phone would flash a gray battery logo and then it would go away, not charging the phone. I read online somewhere, to try holding down, power and home while the gray battery icon flashed, and it did actually start charging again! However, data was still broken. I read somewhere else that someone said to pull the battery while in download mode, which I did, but that seems to have disabled it again, and now the same trick before is not even getting charging functionality back.
I am really at a loss, I am positive I need to do something in Odin mode to get things back together, but I've tried all these combinations and nothing is working. Odin in Windows will currently not detect anything either, so I am in trouble here. Any ideas?

Nothing helps..?
(I will post this also here, cos no one answered @ zukfans yet)
Hi! I think I need to ask help now.
I've managed to hard brick my Z2 with QFIL trying to update the phone from zui 2.something to 3.5. Well obviously that did not end up good.
My phone went to a stage described in some cases: White light blinking every 15 seconds or something and phone vibrating. Ok, I tried to shut the phone down by keeping and releasing after second blink. Did not work. Then I tried to hold for two or more minutes. It seemed to work first but suddenly also that didnt work (kept power pushed for ten minutes or more). Ok, the I made the cable described here. I did a jumper cable from my usb extension cord. Windows reacted to the phone but did not recognize it. Nothing showed up in device manager or QFIL or MiFlash. The phone keeped on vibrating and a left it like this for the night. I guess battery ran out and phone finally shutdown.
I continued and same results. One time windows recognized a unknown device for some seconds but it did not show up in device manager or MiFlash. After that nothing. Now the phone only blinks the light. It vibrates only when trying to charge it or plugged in PC. I don't now if it's on or not. Anyways, the same results with windows: reaction, but no recognition. I've tried to pull usb out and change to another slot etc.
Also I've installed Zuk 1.05 drivers, MiFlash and tried also with Qualcomm drivers. Uninstalled everything and tried again. Nothing seems to help.
Could this be because of Windows 7? Or bad extension cord? Or what...? Any advice would be appreciated.
edit: It was not Windows problem I guess. I installed fresh Windows 10 with no help. Actually worse. No Windows is not reacting at all. Maybe it's the jumper cable I created. I didn't want to ruin my only USB-C.
edit: Ok. Back to Win7. Now there is no reaction at all also in Win7. The phone vibrates when connected to pc. Otherwise phone seems to be off. No lights flashing. If power is held down white led flashes briefly but no vibration.
edit: Now if I connect the phone to laptop the led blinks every 0.5 seconds... I have no idea how turn the phone off. It seems to be off while not touched because nothing is happening...

@Pelepako
Try this,just a copy paste
2.0). Turn off the phone. If the phone boots up (reboots) then immediately to point 2.1
2.1). Put wire on the 2nd contact on the left
. And together with the wire insert into the PC (at the same time the phone is already connected by cable).
2.2). After 5-10 seconds, take out the usb plug with the wire. Remove the wire and insert the plug back.
2.2.1). If you do not have a bootlap, but it hangs on MI, on the boot process, etc. Hold the POWER button and insert the USB plug with the wire into the usb port. The screen goes out and you get what you want.
3.1). Your device in EDL mode.
3.2). Click REFRESH in Miflash and see your device in COM format.
3.3). Flash firmware at your discretion.

Thanks for the instructions.
Still nothing. Windows 10 does not recognize the phone in any way. The phone vibrates almost immediately when plugged in. Then nothing. Sometimes (before) I got Windows to recognize it as "unknown device".
2.0 Turning off the phone. I'm unpluggin the battery. I guess that does the job? At least nothing is flashing or vibrating.
2.1 I inserted a paper clip as in the picture.
Dunno if it's a driver thing. I've installed different Zuk driver version, Qualcomm, MiFlash, QFil, ADB.. you name it. I've turned on the Test Mode in Windows (driver signature). I've tried two different cables. One of them is the original. Tried the paper clip trick and the wire connect trick. Nothing is working. There has to be some flaw that I'm not noticing. Can't be the only one who really got his phone bricked...
About the drivers:
Ive installed zuk 1.05. Is it ok? Tried also 1.06 and 1.08.
How to install ADB. I've used ADB installer and installed system-wide. Should I also install the device driver (Google)?
Qualcomm drivers. Cannot manually install. With Miflash etc. some Qualcomm drivers get installed.
Do I need to install Fastboot and ADB "executables"? Where do I need these in my situation? Nowhere?
What abou QFIL? Is it necessary if I'm using MiFlash?

Ok. Just found out that the only 2.0 port is broken. There is no second pin. At least anymore. I might have broken it in some point.
Other reason for malfunctioning could be the circuit board of the phone. The previous owner in all his wisdom had glued the battery cover with super glue. As I opened it it ripped of some of those circuit materials that conduct electricity. The broken part is near the usb port of the phone. Maybe if I put the cover back it will work cos the ripped parts are still glued to the back cover..

So back to the issue.
The broken part of the phone seems to be speaker so it should not affect the connection I guess. I also fixed with conductive silver paint. Still, no help.
Just found out that the charger and probably also the cable are not original ones. Maybe this is the reason for this is not working. I cannot come up with any other solutions. Now I would need to know which usb cable would qualify for the procedure. How can tell which is a proper cable before buying it? Also does the micro-usb cable work if I have the convertor dongle (Samsung made)?
edit:
Ok. Sometimes the led blinks every 0.5 sec. Sometimes phone vibrates every fifteen or something seconds. Only way to get the computer to react is with modded usb extension cord -> green to black. This way Windows recognizes an unknown device. That's it. I cannot install Qualcomm drivers for this or do anything else. This way Windows makes this connected sound every 0.5 seconds and the phone led blinks. After a while it stops and the phone is marked as "unknown device". Also if I connect the phone to a charger it blinks all the time (0.5s) and vibrates occasionally. Then after a while the led calms down and blinks every 15 seconds. And then back to 0.5s with vibration. All these symptoms seem unclear and I haven't found anyone suffering from same kind of problems...
Really am I the first that really bricked this one? I didn't even use the phone yet. Just checked it and tried to update the system cos it was old version.
I assume that the phone has to be off after disconnecting battery cable so that should not be the problem here.

@narshi shukla
I turned the phone off by removing battery. It does not reboot after shut down before I connect it to computer. Few seconds after connecting to pc it vibrates shortly. Nothing else happens after that. Same with and without the wire.
I've tried so many different methods that I'm giving up with this I guess. Am I the only one who got his phone permanently bricked. After all I tried to flash by following instructions. The flash failed and phone went on crazy vibration and screen on for some seconds after that it was vibrating every 15 seconds. Then suddenly it stopped doing that. Now it does only if I plug it to pc or charger.
The "black green wire trick" is strange. If I only connect those two wires nothing new happens BUT if I connect green to black and black to green by tying instead only touching the phone vibrates and led blinks every 0,5 seconds and windows also makes the connection sound even though it is not working.
