My GS2 was on charge and when I took it off charge the screen was apparently "frozen" and the phone was unresponsive to all inputs (touch screen, power button, recover mode, download mode), nothing work. So I took the battery out to restart the phone and now there is no response. The battery wont charge at all.
My phone is rooted and I had been running Resurrection Remix ics v1.0 for about 3 weeks so I know it was not a bad flash.
Since the battery would not charge, I ran some tests with a multimeter and though the battery is showing an output voltage of 3.7v, when I put the multimeter on the battery terminals in the phone whilst on charge, it was only giving 2.5v. (obviously not enough to charge the battery).
I did purchase another battery just to double check whether the battery might have been dead, but nothing.
Having had the phone for less than 12 months it is under warranty, but I don't want to return it until I have reflashed the stock ROM and unrooted, to avoid any issues. Obviously I can't reflash if I can't get it to power up.
Anyone have any ideas that might help?
Oh, and I do have a USB jig which I have tried to no avail.
Sorry if this has been addressed elsewhere in the forums, but I couldn't find any information to help.
can anyone help
anyone experience similar problem?

I was flashing a new rom. And after it said 100% on the phone it turned black and never lit up again. I waited i didnt pull out the usb. 15 min later i checked it again still black. i pulled the usb out. hit the power button and nothing happend. i did a hard reset and still the phone wount power on. The phone's charging led light wount even come on when i plug it up. So i assume i have bricked me phone ?
I have HSPL3
miri19v
froyostone 3.1v
is there any way to bring it back to life or do i toss it in the trash?
thanks for the help
i have also tried to go into boot loader and NIL!
from your use of the word 'trash' can i assume you have a tmous hd2? if so, what did you flash? was it a non tmous stock rom (meaning a bad radio)?
(oh, first job tho, check for bent battery pins)
the pins are fine. yeah i was actually flashing a stock tmou rom.
got the full filename for the rom you downloaded please? (just checking you havent downloaded a t mobile rom that isnt tmous)
the reason im pushing that line of enquiry is that the symptoms you describe are consistent with either
wrong radio (from the wrong stock rom)
bent battery pin
over discharged battery
to test the over discharged battery you can take it out, plug usb in with wall charger, then put battery in. this lets it charge without trying to turn on the phone. the light may not come one for some time, so leave it a good hour or two.
Hey Sam,
I'm having this issue too. I am relatively positive it's from an over-discharged battery. The phone conked out a few nights ago, and later when trying to charge it I got nothing - until yanking the battery for a bit, plugging in the charger, then popping in the battery. Now, every time the battery drains I have to do this.
Is the battery "damaged" now, or do you have any suggestions to fix the prob? I see this posted a bit but no one has any solutions that I've found.
Thanks!
Ryan
well i know the principals of these batteries, but not really the mechanics, so yes id guess the battery is defective, (but it could be the phones internal battery control circuits too, again just guessing) but no i dont know if there is a cure, other than try another battery, and if it cures it, ok, but if not then it would be a warranty issue.
are you using android? cos from what ive read it discharges quickly under android or something? (never used it so cant tell)
Hey Folks,
I have a Samsung Galaxy SII (SGH-i777) that I used a couple of years ago. It was my first Android phone and I loved it very much (until corporate made me an iSheep).
The phone was retired to a shoe box for the last 1+ years and I recently dug it up so I could get it set up for my little bro who somehow recently fell on his phone with it in his pocket and shattered the screen (don't ask... I don't get it either).
Anyways long story short -- the phone sat idle for a long time, when I pulled it out it wouldn't boot up at all. Assumed that the battery had discharged so I plugged it in to see if it would start up. The battery logo would intermittently flash on the screen and show a drained battery logo but even letting the phone sit for a day did not provide me any results.
Fast forward 3-6 months. Today I replaced the charging board thinking that there was some issue with the USB connector on the phone that was preventing it from getting power. Once that was done I discovered that I was able to get the phone to boot into Odin mode. Great! No boot, no recovery, but download mode seemed to be better than nothing.
I have tried, in vain, to flash stock firmware to this phone via Odin, and even though all indicators point to it being successful, once I finish the Samsung logo comes up on the screen, goes off and that's it. I can see the 4 LEDs on the buttons at the bottom of the phone flash every 5 seconds as well as a faint flicker on the screen staggered between the LED flashes.
Looking for any further suggestions as to what I may be able to try. I have searched various sources on XDA and other sources but I haven't quite found anything that matches my exact symptoms.
Furthermore, I can't be sure what Kernel/ROM I was last running on this phone. Maybe Siyah kernel, maybe CM 10,1 with Flux kernel. Idk.
Any input is appreciated!
Seems I should mention this other detail --
With the battery in, I cannot get into download mode -- it just states 'Low Battery!! Can't Download!!" This is presumably due to the fact that the battery is completely discharged -- maybe incapable of holding a charge but perhaps this is indicative of a more serious hardware failure.
I'd guess the battery is completely shot.
I bought a replacement battery from here: http://www.ebay.com/itm/111014533334?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
No problems with it.

Very likely --
Since you got me to shift focus here, a quick search is telling me that it won't boot without a battery due to a feedback circuit. This would explain the ability to go into download mode but the lack of boot / flashing LEDs I guess.
Can someone confirm?
If the phone was working normally when it was put away, I would expect it to be working normally when it was pulled it back out. Your story is a little confusing, but did you ever try booting the phone with a fully charged battery? In the circumstances you describe, that would be the first logical trouble shooting step. And if you haven't tried that, then it is still the next logical trouble shooting step. Also, you can't assume that the original battery that you left in the phone is still able to hold a charge. It still may be good, but you can't assume that for testing purposes. Incidentally, the battery should have been pulled from the phone before it was put away.
I do not get any indication that the original battery is actually charging. Charging icon just flashes on the screen briefly in between LED and screen flashes (again, presumably due to the battery being completely dead/incapable of holding a charge since I left it in the phone this entire time).
I guess I'll go ahead and buy another battery and see what happens.
It is my understanding then that this phone will not boot on the charger without battery due to a feedback circuit. Correct?

Even if the battery is good, but fully discharged, it may not charge in the phone. You would have to have an external charger. Phones are not consistent, and many phones probably would charge a fully discharged battery, but I have seen a number of people report that a fully discharged battery would cause the exact same behavior as you report. If it were mine, I wouldn't throw the battery away yet.
If you know anyone with an I777, you could borrow their fully charged battery for a few minutes just to see if your phone will boot.
You are correct that the phone will not boot on the charger when the battery is out, although you should be able to successfully flash firmware through Odin with the battery out, and the computer supplying the power, but still, as far as I know, it will not boot after the flash without a working battery.
The battery was indeed at fault. Ordered a new one on Amazon, popped it in and voila -- we're up and running.
Thanks for the input guys! Much appreciated!
Ok so I wanted to upgrade from Jellybean to KitKat today, with Bam-Rom.
I am preatty familiar with flashing roms. But I somehow got my phone to keep on rebooting. I wanted the battery to die, so I guesed I would leave it there drain and then replace the battery (I've got 3). After the phone "died" I replaced the battery and tried to open it. But nothing happens!!!
I've tried all of my 3 batteries, plugging in the cable, tried to boot into recovery and download mode. Nothing happens!
Is it possible that from the multyple reboots (about 15 min maybe) the CPU overheated and got burned?? Is there something I can do to check?
Any advice very much apreciated!!
Charge the battery for half an hour and try again
Done, nothing happens, pluging the cable dosent do anything. However I have an external charger so I know it is charging correctly. Also while I charge with cable nothing happens but the back of the phone get heated so I know the battery is charging that way too
I have opened the phone nothing seems to be burned or damaged what so ever
Replace motherboard. As to exactly what's dead on the board, unless you know how to work with electronics like that/how to diagnose problems (with gear like a multimeter), you're not going to be able to figure out exactly what died. And even if you could, it's irrelevant. You're still replacing the board if you want to fix it.
I recently picked up this galaxy s6 edge from a friend that upgraded to a new phone. It won't turn on, neither to android recovery, nor to download mode nor the android. I charged it via wireless charging overnight and i tried for around an hour with a usb cable. What do i do?
same issue i am facing, i tried original charger, wireless charger and fast chargers from many different brands. but all failed. The device only gets warm/hot while charging and nothing happens. neither download mode nor recovery mode works. I am kind pf stuck without any solution, my device was used very rarely and its like an brand new device. Doesn't know what to do, if you find any solution then please let me know too. thanks in advance
Same problem. If I press power button very long, blue light comes on. Then it's stuck and stays like this until battery is flat. Battery charging is not possible: device heats up (tried USB and Qi), but battery doesn't take any charge.
So I opened the S6 and checked the battery directly. I can charge it directly with a lab power supply and when I plug it in and press power button, the blue notification light comes on again until battery is empty again. I can also see that only ICs get hot, but not the battery when plugging in USB.
So, it's definitely some hardware fault. I suspect power IC that is not able to power up the screen. But I don't know. I will investigate further but it looks difficult. However, I have seen many YouTube videos with same symptoms, but problem was always different than mine :/
Hi guys,
This thread is 2 months old, any of you managed to fix the problem?
I am having very similar problem. My phone was on a shelf for about a year and a half. Before now it was working perfectly. Now I can't charge it via USB or power adapter. When trying to power it up or get into download or recovery mode, nothing happens. Computer does not see it. Tried different cables, USB ports, power adapters..nothing.
The only thing that is happening to the phone is the battery logo appears when trying to charge it, though the green bar does not go over battery, only the empty grey battery with lightning icon in the middle. Also the screen does not go dark after a few seconds as it should and the red/blue LED does not turn on.
Is this the signal from the phone, that the battery is to deeply dischareged and cannot be charged again? I am googling all over the web and can't find anybody talking about what phone does in case of to low voltage on battery.
PS back does not seem to be bloated, USB port was working perfectly last time used
Please try to help, you are my last stop before opening the phone and start probing the poop out of motherboard to see what gave.
EDIT: something interesting happened just about an hour after my post. The battery suddenly started showing % of charge and the green bar started running, computer recognized the phone.. as everything should be.
My FIX: leave the phone pluged in and charging for about 3days and it will start working again.
My semi professional explenation of fix and problem: the phone has a ''backup or reserve'' battery. It is actually main battery but the last I think I read somewhere it is 20% of capacity, is reserved for phone exclusively for the clock and all other electronics that need power when switched off. Now these 20% probably were discharged due to laying around for almost 2 years.
It took me 3 days of charging to fill up these ''20%'' I guess. Probably because Lithium batteries are charged VERY slow at very start and end. This is safty procedure for ALL Li batteries.
If any expert can confirm my conclusion please do so, to help other people.
To answer partialy to my question: The phone tells you battery is ''deep'' discharged when you only see the charge icon without the green bar.
In the mean time I was writing this edit I came up to 4% battery and turned it on!

So, I am having some problems to give a second life to this device.
I bought twice a battery to replace. The first one was clearly a second hand battery sold as new, which lasted 6 months, after which, it started to grow bigger in volume and its performance dropped dramatically lasting half an hour working. I tried to get a refund but no luck.
After that experience I tried a second seller who promises nothing less than 2 years warranty for the battery (wow). I bought a new original one and installed it. It seem in mint condition so I thought it would do it.
It worked everything aparently fine. I even installed a new custom room (i must admit that i am not sure if i did it right) But it appartenly worked. I had cRdroid with android 10 running smoothly on the phone. Not sure at this point if I rebooted after that. I think so.
The nightmare started once the battery ran out (I did it on purpose to calibrate de battery). The phone didn't wake up again. I started to have a blinking red notification led. It seemed not to be charging at all and indicating some problem with EDL mode or with very low battery. The fact is after trying long time charging, several chargers and cables, etc, i managed to get a yellow led light.
But what I can get by now is:
-if I plug a charger with a (sometimes) notification of a stuck 50% level of battery (wtf), sometimes bootloop, sometimes black screen
-Entering in fastboot mode with (vol- + power)
-Not able to enter recovery
-If I try to swich on it does not react to power button in any way.
I tried to flash all stock files by using xiaomimitool but it does not boot system afterthat (although i can get to stock recovery once at least after that)
i tried flashing twrp and it says ok installed but I cannot enter afterwards
and so on..
do i throw the phone away?
btw, it is unlocked and it is rn4 global sd version (mido)
I would have checked the battery voltage before flashing anything.
For me, I would have also taken the old, dead battery and used the the BMS PCB and connector off that and a bench power supply to power it up as a check.

Hello (a bit late).
I find this to be something that I should have done more than a solution now the problem is here. Even tough I don't properly understand your proposition and I find I might not possess the tools that you explain.
I never though that replacing a battery would bring this problems.
I managed to bring back to life the battery. Now is working without problems, but only because I am avoiding the phone from completely discharge the battery and I am charging it before it dies. Otherwise I have the feeling that battery will go under voltage again.
Is there something I can do to avoid this? I have checked voltage with some app and lectures seem to be normal while its working: 4.38 v and going down while it discharges. I do not have the old battery.
