[Q] !!!HELP!!! CAN'T Charge, connect and voice command keep pop up - AT&T Samsung Galaxy S II SGH-I777

I bough a brand new i777 from online (Ebay) in June 2012. The phone come with a stock ATT version android system. It a little lack and slow, but it is acceptable, and a month later I upgrade to Official ICS ATT version.
After I upgrade my phone, my computer would not recognize my phone. Everytime I try to connect the usb cable, and there always a rectangle notification pop on my left Windows. It shows USB port doesn't not recognized something like that, and I try to download Samsung USB disk software. my computer still would recognized my phone. I tried each port in my laptop, desktop, school desktops.
One month later, I flash my phone to other custom roms for several. And I notice the phone battery indicator would not show the % correctly. For example, if the phone has 50% battery, and I can't charge the phone without reboot. I MUST REBOOT PHONE TO CHARGE. sometine phone is charging. I unplug the usb cable, the battery indicator shows it is still charging and the 50% would not change even the battery is full 100%. and I will only see the 100% unless I reboot the phone.
later I flash AOKP rom. This time I can not charge and connect my phone through USB. I have to charge my phone in a Independence battery charger which I have to take out my battery, and put the battery into the battery charge.
Current condition.
Plug in USB and reboot the phone. The battery indicator shows charging, but actually it doesn't charge at all.
Is there anyway to fix my phone? back to stock version!
Thank for reading

One might think something is wrong the mini USB on the phone huh?
Like the tons of others that have had the same, very well known and documented, problem.

[Q] Vibrant not charging.

Alright so my Vibrant won't charge. I JUST recovered my phone from a brick, (I was having issues with the battery life on Slim Roms 4.0 compared to 3.9--in the middle of flashing back I accidently wiped my internal memory. As I was recovering it using Odin, my fat cat jumped on my bed and caught on my phone cord bricking it.) Flashed using Heimdall and was able to get my phone into working order.
Now, I placed Slim Roms 4.0 back on my phone initially after the unbricking to have something working on it, even though the battery life less than impressed me.
So I charged it like normal yesterday, got it to 100% and was fine and dandy with it working. (Still sucking up battery life like a vampire in a fat camp.)
So the update 4.1 went live yesterday, I flashed it immediately to that. The battery life was amazing! So I do the normal thing when I flash to a new ROM. Let it die completely before charging it completely. It's now dead and will not charge.
Symptoms;
I plugged in my normal cable for work (a cheap cable I purchased off of Ebay.) And up comes the round loading symbol. Followed by a darkening of the screen, followed by nothing.
One thing to note, is while it has it's loading circle on, the bottom buttons light up when I touch them.
My Steps;
-I attempted different USB ports since I charge through my work computer. No luck.
-I "borrowed" my co-workers USB cord and USB to wall plug. Attempted the new cable in the computer first. No luck.
-Plugged the borrowed USB into the wall charger. Same thing happens.
-Used my own cheapy cable in wall charger. Same thing.
-Took co-workers complete set and plugged it in in a different room. Nothing.
-Took out my battery, plugged in USB, placed battery back in. Nothing.
-Hold down the Vibrant buttons to get into Bootloader, it resets the loading circle and nothing more.
So now I'm sitting here wondering what to do. I do not have rubbing alcohol readily available, however since it charged to 100% yesterday I do not believe that is the issue, but I'd be willing to try if I had access.
Something you should know, I am using a Samsung Epic 4G battery in my phone.
-For those who might judge saying it is dumb, I have gotten 54 hours out of that battery on one ROM before, that is with texting, talking on the phone and installing apps. I'm fond of this thing, however I have my stock battery at home still.-
Any suggestions you guys have would be appreciated. I have tried things that I found on this forum and basic tech support to no avail. (I am at work so the things I can use are fairly limited. However cords are of no shortage.)
Alright, I unplugged my phone from being plugged into the wall charger for an hour and 3 minutes later it decides to turn itself on.. Not sure what's going on but I'm not going to complain.
So my question now is, can anyone explain this or help prevent this in the future?
From what I've heard draining a battery until it dies can damage it. But, I'm not an expert on that. It's possible that the battery needed more time to recover from the drain.

I had something similar happen when running lithium volt ROM. My battery completely died and the phone cut off (obviously.) I plugged it in the charger and it immediately tried to boot the phone up but it was bootlooping at the startup screen. I let it sit there for 20 minutes or so thinking maybe it is charging but as soon as i unplug the charger the phone cut off. Luckily I have an extra battery, popped it in, flashed a new ROM thinking that was the problem, turns out it was something to do with the ROM(maybe it needed a certain amount of battery power to boot up). My completely dead battery worked on the cm7 ROM I flashed, plugged in the charger and it booted up normally and started charging.

Thank you. I might just have to downgrade back to 3.9. It's almost a shame. xD
I'm going to test my old battery in this ROM just to make sure before I downgrade.
You need to use your Samsung usb charger, and wall adapter only. These two are the only ones that will actually work. I had this same problem and realized it was because I wasn't using the Samsung stuff. Even when pugging into the computer, use the Samsung USB cabe only. As for the battery your using... I wouldn't recommend it, no matter the fantastic battery life you must be getting.

Daw it's a fellow Samsung battery.
Thank you about the cable, I need to purchase another one anyways, mine at home seems to not be connecting very well. :/
ROM. some roms do that. it will not let you power up while charging if the battery is very low. you will get the circle and the battery symbol after. sometimes you still cant unless you pull the battery. happened to me many times

Battery Won't Charge...HALP

My S2 absolutely won't charge anymore Black screen, no charging icon, no lights, no sign of life, nada... Barely had the phone since January. Not sure if it's the port on the phone or the battery. I wish I had a multimeter but I don't. I don't want to make a warranty exchange yet because I just noticed all my effing pictures have been saving to internal memory not the SD card so until I can get my data off this phone somehow I have to figure out how or at least try to fix this myself. PC doesn't recognize the phone of course. 3 different chargers...makes no difference. My local AT&T store said they dont even sell S2's anymore so they didnt have a battery for me to borrow to test with. So once I can get out of the house to get access to another battery to test (which I can't today) all remedies must come from the tools I have on hand at home which is you guys and Google LOL All feedback is appreciated

Yeah, no dice...I'm leaning towards the problem being the port. The phone is unresponsive battery in or out, PC connect or wall charger...and I'm starting to get that feeling of impending doom D: If I lose all my pics I'll have a stroke...Coulda sworn they were saving to the SD card...
Do you know anyone with the same phone? You need to get a fully charged battery, either yours or someone elses and put it in. If the phone boots, then it is probably the port. Worst case, you'll have to buy a battery.
In that case, you can get the pics off via wifi. Dropbox is one option for that. If you need to flash back to stock, that can be done without a usb port also. Any questions along the way, just ask.
Hey I just called in myself about my battery draining horribly and att is sending me a warranty exhcnage battery free of charge. Try it. Just have to wait up to 5 days. Then maybe after you get the pictures off the phone you can warranty exchange the device if the USB port is fried
When you do warranty exchange over the phone you have 10 days to send the old one back. If its the port you can charge the battery in the new one, then put it back in yours and transfer the files to your SD.

OK, well the battery is fine, it's the port. Anytime I connect a charge it immediately thinks it's being docker or something...won't charge or transfer data.
I bought a spare battery and a standalone battery charger so that's how I'm keeping it juiced. Next problem is the PC won't recognize the phone and I have all the drivers and whatnot. Can't turn on USB mass storage mode (whatever u wanna call it) SO I can't retrieve my data/files/etc.. or unroot the phone...unless someone has some suggestions. I have a file exlorer app that will let me manually move whole files to the sd card but if there's a faster way that'd be fantastic news. I gotta get this phone exchanged ASAP :crying:

Yes brand name, almost $20.00 but it charges now. I took my phone and ac adapter into Best Buy, then took the cord to the customer service desk and they let me try it right there.
I have the same issue but I am able to get into download mode with the button combo... it just seems like the battery wont charge...
Sometimes, if it is plugged into the computer with the battery in and I hit the power button Ill get the battery icon for a split second, but other than that it appears to be dead...
any ideas?

[Q] Not Charging. Could be bad port.

I have had this s2 for less than a year so the battery should still be good and has been up until today. I plugged my phone in last night to charge over night as I usually do, but when I woke up it was completely dead. I tried 3 different cords and many different ports and wall sockets and it still does the same thing, which is nothing.
The phone seems very sensitve as to how I have the cord plugged into its port. I have it plugged in now but I have to keep watching it because it will randomly stop charging. Well, it's barely even charging anyways. It keeps going back and forth between 6% and 7% charge. Would replacing the port fix the issue or is it a problem with the battery? Any help or info would be appreciated.

I just got the replacement port board in the mail and the phone charges fine now. However, once I put the board in the phone is saying "Emergency Calls only."
I've tried taking the sim card in and out and restarting it and what not and it still says the same thing.
Is the phone recognizing that it's not the original part or something?

You weren't on 4.0.4 were you??
This looks kinda messy.
If you were in 4.0.4, as rat said, you could be lucky as you probably have a brick due to the brick bug.
Of course, your warranty must still be standing.
Why? Because it's Samsung's fault, not yours (of course it is, they don't need to know tho).

Straight Talk Samsung Galaxy S2 won't charge?

As of last night, whenever I try to connect my phone to either my outlet charger, my xbox, my computer...anything, it never even charges. The icon on the screen still says, "Connect your charger" even if it's connected. The sound doesn't even come on, and the battery icon doesn't move when it's connected (obviously, because it's not charging lol). But the only way I can use my phone is by charging my battery first. (Luckily I had a spare battery that I had already charged) and now I'm looking to buy a battery charger so I can switch battery's whenever I want. It'll be a pain in the a**, so there must be a way to fix it. Sometimes when I disconnect my charger, the icon pops up saying, "USB Connected". I've tried 4 different chargers also, and still no luck. I still haven't bought my warranty so I don't know if I can still do that and exchange it.
Any suggestions? I already tried different battery's, removing the battery for a couple of minutes, charging the phone while it's off (it seems to work but the battery icon goes from 1/4, 1/2, 3/4, and to full, then back to empty, and it does it again, but it freezes and it takes awhile and then finally it does it again, but it doesn't really charge.)
My phone IS rooted, and I have ShoStock3 with Clockwork Mod. I'm thinking of reverting back to my Clockwork Backup from March but I don't think that'll work. I don't want to loose anything from my Internal Storage that I may have stored.
Please help

Edit: Nevermind, I did my research and found out what it's for lol. I don't think I'll want to go that route, I hate taking apart computer's or phones because I'm not good at following instructions and I sometimes loose the parts lol.
This has happened to me three times. It's the charging module. You have to get it repaired I'm sad to say.

Hi..first try removing the battery from the phone for about 10 secs and put it back in and see if that will help, because the battery should still be in a charging state even if the battery was not that good as this has happened to me on other samsung phones, and if not better re-install the rom you have, but make a backup first if you can..worth a try before proceeding further.

I have the latest stock rom installed, so, i don't think it is a rom issue. Besides that, how can i re-install it if i can't turn my phone on? Now i have something 1 or 2% battery life =/
I've tried to remove the battery a couple times, 10sec, 10min... nothing seems to work. Since i have warranty, i'll have to use it, the problem here in Brazil, specially in my city, the service takes forever(3 to 4 weeks =/)

Oh okay I didn't know you could not get into the rom or past that battery icon..then most likely a port problem forsure..did you try another usb cable to just make sure.
Edit: when you have your usb cable unplugged from the phone it should still boot into your rom as the port has nothing to do with that part..what does it show on your screen when you boot the phone without the usb connected.

This happened to me last month on my 10 months old Mega. It was driving me crazy. Phone was charging just 10% / hour (as opposed to 60%). I tried charging with other chargers but result wasn't different.
After much research I came to know that my phone did not have any of the following problems
- ROM (stock 4.2.2), my phone was going into good deep sleep etc.
- Some app (I factory reset my phone to rule that out)
- My charger (I used others')
- My USB port (I always use wall charger)
The problem was with the freaking charger cable (weird right?). I took my friend's charging cable and used with original charger and my phone was back on track.
I still have to buy a new cable. Just researching to get a good one (weird again).
I found the Mega does tend to get hot sometimes where the battery is. I think it's faulty connectors. One of mine looks a bit discolored. But who knows.

Okay, so I just this moment joined the forum JUST so I could thank Member hopsin444 for this advice. Just as he guaranteed, it was the charging port. After getting his advice, I downloaded the PDF User Manual for the Galaxy Mega (my phone). I did what another member suggested and unplugged the battery for 10 minutes (just to be safe). I plugged it back in, and used the brand new charger and cable that came with my phone. I had been using a different charger, so I wanted to get a brand new clean start. Sure enough, the battery started charging immediately, good as new. I must say that in order for this method to work, you must insure that all components are in working order: battery, charger, and cable connectors. Because, otherwise, it's hard to debug exactly which little part is the culprit for the problem.
Once again, thank you ever so much hospsin444. You saved me a lot of cash, trips to the repair shop, and untold headaches.`
Update: The phone charge from 66% to 70% and then stopped charging again. I'm thinking it's the little slot -- on the phone itself -- that the charger cable plugs into that is the problem. My only option now is to take the phone to get repaired. But my thanks to hopsin still applies. It was fun while it lasted.
Similar problem. . . . grey battery issue ( can get around by using reboot command either in download mode or stock recovery ) i have 2 batteries and one still has a charge, replaced usb port ( NEW BOARD - $15 on -ebay) but no love . . . . when i power off it sits there with the grey battery icon and kills the battery. it is NOT recognized by computer and does not recognize a charger ( i have lots and they are all good wires and blocks ) ordered a wall charger and can use it but no USB at all
Any help or ideas are welcome
fyi :
completely stock
never dropped, wet or abused just stopped working right!

Your not the only one, this just happened to my Mega at the end of July and i replaced the port just the other week and still nothing. Only way it charges is if it was off...i cant charge it while its on, the battery depletes itself and on top of that i can't even use my portable battery to charge this phone. The cable has to only be a Samsung issued cable and that doesn't even make anything better. I'm just going to officially retire this phone and get me another phone
(Third Galaxy phone model.......and my LAST)
Replace USB port Had the exact same problem Phone would charge then not

I figured out two other reasons why my phone was charging poorly even when I replaced the USB port 1. The charger wire was weak (yes it is a Samsung USB wire) and needed to be replaced. I wasn't getting enough power from the outlet to the phone and it would stay at a percentage for 30 minutes or longer and 2. There was a Low Battery Dump setting that was off (similar setting like the SGS3 and SGS4)
But one thing that now gets me is why I can't use my portable battery to charge anymore? Nothing is wrong with the battery (it charges all of my other electronics with no problem)

Could I try to cover it with a towel then put it in a bag ant it in the freezer for 12 hours and take it out and let it reach room temp
I'm having the same exact problem, did you figure out what the problem was?
sometimes change the plugin charger can resolve the problem, but if you have change the plugin and still can not charge like mine maybe
using charger 0.7A can resolve the charging problem, very slow charging . OR using 2.1A charger but try and error until found the perfect one. (it works on my mega LTE)
Me too, having charging problem with my Mega 6.3 i527m. : (
I had used different chargers, cables and batteries, still the problem of not charging was unsolved.
But when the original usb cable and Samsung's proprietary 2A Traveler's charger that came with my old Samsung Tab 7.7 were used, my Mega detected it immediately and the grey battery icon flashed off and on faster than before - a good sign it was charging.
So, that means my charging port/flex is not defective.
Lesson Learned: It pays to use the original accessories that came with your device or gadget!
