hi,
i'm not sure if this is the right place(or maybe in android dev forum), so let me know if you know a better place to put this thread.
i have a strange problem with my phone:
1. after charging battery stays at 100% all the time, even after a day, only after a reboot it gets fixed.
2. when powering off the phone and connecting to USB, the phone showed green battery icon, now it doesn't it just start to boot.
3. usb is not recognized by the computer anymore.
i cannot use the usual combo to get into recovery, i've managed by pulling out the battery(the download mode procedure) to get into recovery ?!
just noticed another strange thing, in battery status i see unplugged for 0 seconds, even though the phone is unplugged for an hour or so.
i've used nero V3, and thought maybe putting new rom will help.
so i've installed M3 flagship.
but still problems 2 and 3 remains(problem 1 i didn't check yet since i don't have
the accurate battery mod)
thanks for the help.

got excited for a moment thought some one had an answer for me
Those are weird problems. I would just start all over and odin back to stock. Then flash whatever rom you want. Don't forget to check the repartition box in odin

Sounds like it could be an issue with the micro USB port on the phone.
Just to make sure it's not a software issue try flashing back to stock JFD using Odin and see if it continues to happen.
can't odin back as my computer is saying that "the device is not recognized" and the phone still shows full instead of not charging when i disconnect it from the computer.

So while the phone is unplugged and stays unplugged if you pull the battery then put it back in does the battery charging screen still come up on its own even when unplugged?

yes,
while when the phone is plugged in and im pulling the usb out, it still shows that it's charging. only after boot it get fixed.
Plug usb to computer. Pull the battery. Hold both up and down volume buttons together. Plug usb to phone. Then put battery back in. See if that can get you into download mode

if you got the vibrant screen, that's not bad. What error in windows? not recognizing usb? the usb not recognize...does your pc have antivirus with latest def? what os version were you running on phone? have you made any changes to your pc lately like install anything? if not, have you try cold start your computer?
can you get into download mode?
try this [while power off or pull battery, put it back] hold down both volume + and -, now hook in usb cable, it will power itself up and put it into download mode.

i get in windows the "usb no recognized error" i see in device manager "unknown device"
i did reinstall the samsung drivers on my windows 7 x64.
i've also connected it to a vista 32bit with the same error, and my friend's windows 7 x64(he has i9000) and didn't get any alert at all from windows ?!
i've tried with:
nero V3
flagship V3
bionix-v
one more thing is, when looking in SGS tools on battery status i see the voltage/ADC/VF ADC values change all the time but the value of level stays at 100%
update: now i see in SGS tools that the battery went down 80% so this part works fine.

ive got the same problem. Flashing back to stock wont work.. For me it seems hardware related. Ive heard from other forums thats its corrosion in the usb port itself. Im gonna try cleaning it even though im sure thats not gonna fix it. On my phone my battery indicator will stay at 100% untill its been used for about 50% of battery then it will start reading correctly. Of course when you plug it in the charging indicator stays on untill its 100% even if the usb is not plugged in. I flashed back to stock using odin. as long as you have a usb connected notification load up odin with everything plugged in hold pwr+vol up+down untill your phone turns OFF then let go of just the power button you should see the robot digging. Then you can do whatever you want with odin, which at this point of my frustration isnt s*&$.... I really think that its just a crappy usb port design.... Let me know if you find something out.
OK guys, finally I have fixed that issue. Problem is with micro usb(corrosion). You just need take battery out, and clean micro usb port with alcohol and tooth brush very good. That's all what you need to do.

Right now mind shows that I am connected with a USB, when I am not. will this fix my problem?
my note froze up for 5 minutes so i took the battery out and tried to power on by button but no response have been on the charger for hours and nothing. I plugged it in to the computer and is recognized but phone wont show any life. I tried all physical button combos and took battery out for 10 minutes. Phone is and has never been rooted. please any help.
can you get it into download mode?
1. Disconnect the phone from your pc or wall socket
2. Plug a usb cable into your pc, but not into the phone yet
3. Remove and replace the phone battery
4. while holding the volume down and power buttons, connect the phone to the usb that is connected to your pc
If you're in download mode you'll see a big green android guy with the word "Downloading..." underneath.
Not sure what could've gone wrong, but if you can get into download mode, then there is still hope yet for your device.
If you can get into download mode, and you are willing to try some things, it may be possible for you to flash a stock recovery using a tool like Odin. There are guides available for this, like the one here. I would wait on some of the more experienced folks to put in their 2 cents still...like i said, that has never happened to me, so i'm not sure what could be the problem...

U sure u never tried to root it or anything? Either way that's a hard brick my friend, it can't be fixed with software, you have to send it in for repair, or warranty that sucker. I suggest u just warranty
I had tried to update my phone via Kies and the computer blue screened. Now the phone is stuck on the ODIN Mode screen with a picture of my phone on the left, a yellow triangle in the middle, and a computer on the right. Taking the battery out does nothing, restarting does nothing, restarting while holding down the volume buttons does nothing. No matter what, it always comes back to this screen.
When I plug the device into my windows based PC and open ODIN, ODIN does not see my phone. When I plug it into my linux computer and run lsusb, it does not list my phone in the output, so the computer definitely isn't recognizing that my phone is plugged in. A couple of weeks ago, I had this problem while trying to back up the phone, so I'm not sure if it's related to the botched upgrade or not.
Does anyone have any tips or advice here? I'd really love to be able to use my phone again. I am using the cable that came with the phone. I have the same results with other cables, as well....
I'm happy to provide more information if needed. Just tell me what you need to know.
That screen is a form of download mode. You should be able to flash stock or stock plus root from there.

If this statement reflects what you actually did, then it suggests the wrong order. You must first open oden on the desktop, and then connect the phone to the computer in download mode.
Try that first.
Next you could try putting the phone into download mode with the battery pulled out. Open Odin on the desktop, then with the battery out, hold down the vol- button while plugging in the usb cable.
Thanks for your response.
So I went ahead and cleared out everything and then reinstalled the USB drivers. Opened ODIN, connected USB to computer, took battery out of phone, put battery back in, held down volume buttons and inserted the cord. The screen immediately loaded up the one I spoke of in my first post. Odin still did not recognize that I had my phone plugged in.
So then I installed Kies and went to the firmware restoration item under the tools menu. Entered my model and serial number and put my phone into recovery mode according to the instructions there, but the "Start Upgrade" button was grayed out and never became clickable.
One thing I did notice while doing this (On yet another new computer) is that when I plug in the phone, I get a "USB Device Not Recognized" error in Windows. I'm not sure if this is a result of it being in download mode or not, but I thought it worth mentioning. I did attempt to blow out my mini USB on the phone for good measure, but had the same result, even with another cord.
On ur Windows pc, did u try different usb ports ? And don't use a usb hub.

Yes, multiple ports on multiple PCs.
The port was working fine yesterday when the Kies update failed.
Have u tried using a Jig to get ur phone into download mode ??

First of all make sure that your PC isnt running Kies in the background - Use Tsk Manager to kill Kies process
Then Plug In your Phone
Enter Download Mode by holding both volume buttons and powerbutton till the Boot Screen Appears.Let the power button go when you see the boot screen but keep holding the volume buttons.
In no time you'll be in Download mode
Then go to odin and check if your computer recognises it. Odin willl show you (Com:x) X - Any Number
Then you can easily flash stock rom or a custom recovery..

I have already made sure Kies is not running (And have tried this on a computer without Kies installed) and according to creepyncrawly in the second post here, the screen that I'm seeing IS download mode.

I tried everything you did, and the only way I got Odin to recognize my phone was use a USB jig to get it into the download mode other people are talking about

I'm definitely open to making one, but I'm confused since everything I'm reading says that the screen I described IS download mode, just with a different screen. Are you saying that you had the exact same situation as me and a Jig fixed it?

You could order one fairly inexpensive. But order it or make it still takes some time. But as several have mentioned, it may help.
Did you try forcing download mode with the battery out as I suggested in the second post?
Yes, I have tried forcing download mode by taking the battery out, holding down Vol and inserting it again. These are also the instructions that Kies gives, but it didn't work there either.

My phones update failed and I got the same phone, triangle, computer. I tried different USBs, different USB ports, different computers, tried Odin, nothing worked. As soon as I found my USB jig that was lying around, and plugged it in before I put in the battery, and the regular download mode which I am used to seeing showed up. ODIN recognized the phone and I flashed back to stock ICS rooted I downloaded from XDA.

That's different that what I suggested. Remove the battery and leave it out. If you have to, sit on it so you won't be tempted to put it back in, lol. While holding vol down button, plug in the usb cable. The usb will supply the power. The phone should boot into download mode.

I guess I misread that. I blame it on my stressful week ending with no phone
So I just did that and boom, download mode as I would expect loaded up first time, no issues after I held down both Volume buttons while plugging it in (Holding down just Vol - didn't do anything). Unfortunately, it still did not show up in Odin (Kies background processes were all killed and USB driver IS installed on this computer and Odin WAS open before I plugged the phone in)
So I unplugged, opened Kies, and was going to try a restore through there since I could finally get download mode working properly. Except when I tried it this time, nothing happened. I held down the vol buttons, plugged it in, got a single vibrate, but nothing showed up on the screen. Unplugged, put the battery in, and it turned on and screen worked. Took out the battery and just plugged it in and the screen worked after vibrating 6 short pulses (It pulled up the screen mentioned in my first post). Unplugged, held down vol buttons and plugged it in, same thing. Blank screen.
Now I'm really at a loss. I'm starting to wonder if there is something wrong with my USB port on the phone itself.

Hi there,
i have same problem with my Galaxy ACE GT-S5839i: i can't get ODIN to detect my phone. Originally, i tried to flash my phone and made a mistake in the process (installed a ROM before i installed CWM). This caused my phone to stop booting. The only thing remaining working is the download mode. But i can't get ODIN to detect. I tried 2 PCs, different USB ports; i tried to install Kies, or just the drivers... nothing makes ODIN detect my phone... I hear my PCs detects the phone when in download mode (it bips) and my PCs both recognized my phone (Samsung Mobile USB CDC Composite Device). On PC uses windows 7 and the other Windows Vista. I ran ODIN v4.38 on both... Would be grateful for any idea what to do...

I had the same problem with kies on a sprint s2. EXACT same problem. Cord got jerked out in the middle of Odin flash. THE ONLY screen i could get is the one you described.
Also went through the steps with keis, dl firmware, got to the last part but the start button was greyed out. I had to do this several times and finally the start button lit up. Idk why it didn't work before but it finally did. Have you tried doing it more than once?
I wished i could be more help but that was my experience. Maybe it will work for you.
I was using CyanDelta for over months without any problem. Today (1 December 2013), I downloaded an update of about 21 MB of Cyanogenmod Nightly 10.2 for Samsung Galaxy S2 SGH I777. While trying to install it, the phone booted into recovery and installed it. However, during the process of Upgrading, i.e. when the screen says “Android is Upgrading”, “Optimizing App”, the phone got stuck at “Optimizing app 271 of 313”. I waited for about 30 minutes before I manually switched off the phone using the power button. Then I restarted the phone and saw a new boot logo of cyanogenmod; but it got into boot loop. Then I booted into recovery and manually installed the new zip (of 1 December 2013) found in CyanDelta folder. Still the phone could not boot. Now I saw “Samsung” logo only once and then the phone completely turned off. Now I could not turn my phone on, nor could I boot into recovery or download mode. Also I fully charged the battery before flashing the new Zip.
I tried all other steps to boot my phone like removing the battery and pressing power button for a minute, plugging the usb cable into PC and pressing the volume down button and also all sorts of other key combinations. Nothing could boot the phone. Please help. Is my phone completely bricked or is there any issue with my battery ?
Phone : Samsung Galaxy S2 SGH I777 (AT&T)
ROM : Cyanogenmod Nightly 10.2
Battery Condition : Poor (But it was fully charged and also charger was plugged in while flashing the Zip)

Alright, head over here (http://forum.xda-developers.com/showthread.php?p=18630030) and read this thread by creepyncrawly.
It works. Virtually everyone who's ever had this phone and flashed custom stuff has had to use his guide at some point, so I promise you it works.... IF you follow the directions!
Good luck.

I will definitely try your suggestions and for that I need to buy a USB Jig (as I am unable to boot into download mode). I will get back to you once I get the Jig. Hope I could boot into download mode using USB Jig. Since my phone is hard bricked, will a jig put it into download mode ? As I have read in various other forums that usb jig works only if the phone is soft bricked.

I have no idea what CyanDelta could have done. A firmware hard brick would usually be due to a damaged bootloader. Hard brick means no sign of life what-so-ever. If there is any sign of life, then there is hope. You need to get into download mode to proceed with recovering the phone. If you are unable to get into download mode by any means, then you probably need a jtag repair.
I can't tell from what you've written what you have tried so far to get into download mode. So, here are four ways to possibly get the phone to boot into download mode. Try each one of them before you give up. Also, remember that you must have a good working USB connection as well, especially with the battery out.
1) With the battery in, and the USB cable plugged into your pc, hold down vol+ and vol- but not power, and then plug the USB cable into the phone.
2) With the battery in, and phone connected to the pc via USB cable (plugged in at both ends,) hold down the vol- button.
3) With the battery out, and the USB cable plugged into your pc, hold down vol-, and then plug the USB cable into the phone. The USB cable will supply the power.
4) With the battery in, insert the USB jig.
Any USB jig you can buy should work. They are not phone specific. The only critical factor is that the resistance value must fall within a certain range. I don't remember the exact numbers off the top of my head, but I havn't seen anyone complain about bad jigs since Captivate days.

Thanks for your instant replies. I tried all the above methods except for the last one i.e. usb jig method. None of them worked. I think my phone has no sign of life. I will have to try with USB Jig and then lastly jtag repair.
Even the usb jig could not get me into download mode. The phone is hard bricked.

yesterday i went from citrus to slimrom. Dont know what caused this, but I havent found anyone else with this problem when i tried to search for it.
This is what I have found out:
1. If I connect my charger when the phone is on, nothing happens (cant seem to connect it to the computer either..).
2. If i reboot it with charging cable in. it hangs with the "blinking red light".
I can reboot it by unplugging the charger and pressing power button a couple of times.
3. If I reboot it and let it boot to mi-logo, I can connect charger and it will charge.
This is the only way I have found it to charge: reboot, wait until logo and then connect charger, it will charge every time. Never if I connect it when the phone is booted).
Anyone know how to fix it, the phone works perfectly otherwise.
I have tried this:
installed CM 13, with cm 13 firmware.
installed Citrus again.
Installed exodus MM-rom.
nothing changes this.
The phone came with unlocked bootloader when I bought it from ebay, guess it is unofficially unlocked? Any way to check if its unofficially or officially unlocked? does it matter?
Sounds very similar to what happened to me and it was because the bootloader somehow locked itself again. I just plugged it back into my computer and unlocked it again.
Thanks, but when I try to unlock it with mi unlock tool, it says "couldn´t verify device, no need to unlock"...
I can enter twrp, is my device still locked but I can enter recovery?
Update: I have tried this:
Flashed a stock rom, relocked bootloader, still had the same problem...
unlocked bootloader officially. Rooted and installed krexus rom, still have the same problem...
Found this thread: https://xiaomi.eu/community/threads/redmi-note-3g-not-charging-no-pc-connection.26290/
Does anyone know how to enter engineering mode on rn3sd?
Anyone know if I can short circuit the charging port like described in that thread?:
"After connecting a faulty USB cable my phone stopped connecting to PC and charging - It shows the symptoms of being in USB Host mode permanently.
I was able to charge the phone by entering engineering mode (Dial *#*#3646633#*#* ) and going to the Hardware Testing tab, scrolling up to UART/USB switch and selecting UART
The phone would then charge normally."
"I had that problem too. And I did what u did too.. the problem is that there is some sort of confusion between Otg and USB... so you will have to short circuit the charging port to revive it.
First open up your phone. To make the internal components visible.
Then connect ur charger to the phone.
While the charger is connected, use a flat metal or wire to short circuit the charging port. You should see a small spark and your phone would off.
Connect battery and Switch it back on. If it doesn't work try again for three -four times. If it doesn't still work then send your phone for repairs.
Don't be afraid, it's only 5volts your phone won't blow up. Short circuiting the charging port would revive it..
I did that to mine and it has been working well till now. "
Holy crap my usb has been busted for a while now (charges only and no usb to pc connection) and I might just try this

Let me know how, i dont know what to do
FIXED! Suddenly it works.. I have used a couple of different roms. slim 7, miui, slim 6 etc.
Flashed the new zephyr 7 rom, and suddenly my phone can charge without rebooting!
Just wanted to update the thread if someone gets the same error!
