[Q] Help with empty battery icon LOOP - Galaxy S II Q&A, Help & Troubleshooting

When i plug my charger into my phone it just turns on then goes to the empty battery icon and then shuts off.. then it starts again and it does this loop until i unplug the charger!
Anybody that has a clue why it does that?
Thanks!

Is your phone completely drained? Might be that the charger isn't feeding the phone enough power. Just a shot in the dark, you could try taking the battery out for 5 minutes or something.

Tried pretty much everything.. The empty battery icon juist loops, first it turns on then turns off and it keeps on going like that for ever. I have flashed both kernel and firmware. The flashings were unsuccsesfull..
What does the charger need in the system files to actually give the phone power? I mean i have charged if for serveral hours without any luck..
If i go into download mode it just tells me that i got to low battery and that i cant download..
Plz help someone!

Charge battery outside of phone then flash a stock rom via Odin and download mode .
That not possible you need a service centre .

Any tips on how to charge it outside the phone? I don't have any external charger..
And what isn't possible? Are u refering to what i said about low battery text in Download mode? Cuz that is what it says everytime

[Q] phone won't charge

Hello,
as title says my phone won't charge. I plug it in and all it does it shows battery and white circle for a few seconds and then turns black. And that repeats. I am trying to get into download mod but it says that battery is to low.
Any help please?
Why download mode ??
Battery faulty charger faulty first two steps .
jje
It can't be charger because i hooked it up to pc to. And same thing. Why in dl mode? Well because i updated cwm and i guess darky rom does not support it or something. And now i want to put on new rom and then recover my files.
anyone alive at this forum?
Return to Samsung service centre no warranty custom rom .
Or take to a phone guy looks like battery problem or phone hardware .
First use logic and replace battery .

Had once the problem that the GS2 wouldn't charge at all, don't know why or how it became that way it was just there.
My final solution was pull the battery out, press the pins where the battery normally connects when you put the batter in, just push em a few times down and let them jump in normal position, can be that one of them doesn't connect good / like the spring behind it that pushes it to connect to the battery is some how a bit jammed.
Just give it a try
For me this was the fix and didn't have charging problems after it again.
why would be something wrong with battery?

Charging a drained battery

Ok, I tried root, installing a new recovery and then installing CM 7.2
1) Photon Torpedo for root - no problem
2) Installed CWM recovery apk - and then boot into CWM recovery - no problem
3) Backup system to sdcard - no problem
4) install CM7.2 + gapps - it flashed no problem
(now as you can tell, i forgot to unlock the bootloader)
5) reboot - PROBLEM
I got the "Failed to Boot 2" error, i had it plugged into AC and had 70-80% charge when i started, however, i let it set after the reboot for 20 or so minutes, was off doing something.
I tried rebooting a couple of time, same problem
EVENTUALLY: It would simply not turn on anymore, i think the battery is drained and it will not charge being plugged into wall socket or USB.
How do I get it to charge?
- Do I find a friend with a photon running stock that i can put my battery in, will it charge that way?
- Can a sprint store simply charge the battery for me?
I figure once I can get that going, I can run RSD lite and recover via an SBF image.
Thanks
This has happened to me.. battery drains and doesn't whant to boot.. what I do is.. take battery out., plug in ur charger.(sometimes you get a white light,) press power button, YOU KIGHT HAVE TO TRY SEVERAL TIMES until the green light comes on..but once you see it put your battery back in.. and it should start charging.

When I say several times.. I ment unplugging your phone from charger, plug back in , push power button.. and again( until it powers on) not just pressing power button until. Didn't know if I specified well enough. Hope this helps.

i actually tried a different usb port a bit ago and have a white indicator light on now while plugged in... not sure what that means
I will try your way in a bit if this doesn't mean anything useful tho... thanks
K, am nor really sure what the white light is either.. I just know, on stock when you plugged phone to charge (being dead) green light turns on,screen Motorola logo shows then goes to a battery charging animation.. the white light did nothing for me. But hope you run better luck.
Sent from my MB855 using XDA App
after about 5 minutes i got a green light now... maybe the software for the battery charge display got whacked when i wiped system and tried to install CM 7 - but the hardware part of the charge works.
The only thing I can think of is that white means: i'm charging, but don't try to boot me up at the moment.
I also notice, once it gets a charge it tries to automatically boot - anyway to avoid this?
If its charging you should be able to just boot into RSD lite mode without the phone trying to boot into a ROM..
Sent from my MB855 using XDA App
If the phone is off and u plug it to charge, it shouldn't boot into the ROM, yes the Motorola logo comes up as it does when u turn the phone on, but then goes to charging..
Sent from my MB855 using XDA App
Well, every time it boots i get the
"Failed to boot 2"
Something about NvFlash (can't remember the text)
"Battery to low to flash"
Then it is just stuck there, but not sure if it is charging at that point or not... but not sure if i have enough battery to RSD Lite an SBF image

Mine boots into *nothing* i forgot to unlock the bootloader so the rom i flashed gives me a "Failed to Boot 2" every time it powers on
K, let me power my phone off and kinda try to recreate the "not charging while plugged in" problem.. (sometimes it happens when I power off.) And ill see wich method gets the phone to just charging.. br
worse comes to worse, i know someone with a photon and i can ask if i can charge my battery in their phone
Just tried it.. and yeah phone wouldn't boot or charge by pressing the power button or connecting to charger.. but I did what I always do.. pull battery, connect charger, green light turns on, I insert battery, and goes to charging.. I also tried goin on RSD lite mode without battery inserted. And I got the same error about battery to low to flash. Have you tried this method I just wrote in this reply to get battery to charge?
Sent from my Mopho Cm7.2
Here are a couple things i tried
1) remove battery
2) make sure phone is not connected to charger
3) plug in charger
4) logo appears - says "Failed to boot 2"
5) as "Starting RSD Mode" starts, i have inserted the battery
6) I still get "Battery is too low to flash"
also tried tried with vol-up (Fast boot mode) and vol-down (NvFlash recovery mode) - and ultimately i get "Battery is too low to flash" no matter what
Thanks for the help, however.
side note: found an external battery charger for the photon on amazon for $4, i might just buy one.
Did u insert battery before logo appears? If so, then I am out of ideas, lol hopefully you can get it working soon.
Sent from my Mopho Cm7.2
I just tried something like that now. The charger is plugged into the wall outlet. Basically i plug it in, green light comes on, quickly snap the battery in place before logo appears
I get the logo and the messages at top as normal, but at that point, i don't think it is charging anymore
Lol darn it.. at that point am out of options.. sorry it didn't work.. btw how you forget to be unlocked lol.. anyhow I would go to your friends, borrow his charged battery just so you can get to stock, and start fresh, then return battery obviously, lol
Sent from my Mopho Cm7.2
Yeah i have to charge it elsewhere - i just read some other threads here about people messing up their boot with a "Failed to boot 2" error, the system simply will nto charge a battery at the boot loading screens... so, I bought that charger off amazon for $7 (including shipping), be nice to have it if i continue to fiddle with the phone.
for the next few days... people can't call me... whoop de doo. However, I am pretty certain it is not bricked, so i'm not freaked anymore.
Still, thanks for all the help you tried!
Could you post a link for that charger, I have a second battery I would like to be able to charge.
Lol.. well there u go,

[Q] Stuck in a bootloop with Siyan 3.0.1

Okay guys and guyettes, I flashed the Siyah 3.0.1 kernel to my lovely S2 but my battery died overnight and now the darned thing won't boot. Due to an issue with the kernel, it automatically tries to boot when the phone is plugged in to charge, but not having enough power to boot up the thing dies and tries again. Continuously. It won't go to recovery mode and if I try to launch download mode it tells me it can't because of the low battery and then starts bootlooping again. Please please help, I've been without my phone for a day and I'm away from home with limited internet access so I REALLY NEED IT D:
pull out the battery keep sometime out, and put back and leave it for 1-2 hours for charging....then boot and restore your previouse kernel
I've tried leaving the battery out overnight, but whenever I put it in and try to charge it just does the same thing. Automatically tries to turn on, doesn't have enough power to power on, shuts down, and tries again :-/
You need a new charger battery or find some way of charging your battery outside of the phone.

Did you use SetCPU or Voltage Settings app to tweak with the frequencies/voltages? Theres a high chance that the Siyah you flashed doesn't support the frequency you have on your device. Id tell you to go into that app and restore defaults.
I was on NEAK before and flashed Siyah on top of it and it constantly kept rebooting and then i realized that if you get constant reboots, they mention to play with the voltage settings.
Try it out, maybe lower it from 1200Hz to 1000Hz being the max.
Let me know if it helps!
Happened to me once when I let battery run down too much. I left it charging in bootloop for a while, then unplugged charger, boot the phone, and replugged charger.
Well that was the issue of the kernel but it was solved later. For ur problem try to charge ur battery using master charger. Also try to go to recovery mode while charging and charge for a while and reboot ur phone.

I've left it "charging" in bootloop overnight but it still won't turn on enough to set it charging properly :-( it also won't enter recovery mode so I can't leave it charging at that. My housemate back home has an S2 so it looks like I'm stuck without a phone until I can get back and borrow his phone to charge my own :-/
Hmmm. This is a long shot, but try this: plug the phone in. Then, while it is booting and the phone is still plugged in, take the battery out. (this used to work with my old Motorola Milestone - it would stay on even when the battery was out)
If it stays on, put the battery back in and hope for the best. Otherwise, you'll need to either acquire an external battery charger, or wait til you can borrow your buddy's phone to charge your battery.
Plese change such headings.....
A request to the members to change such headings...which directly give a bad impression of a product wich is an outcome of very hardwork of some dedicated devs....this may be only your case with Siyah kernel which might be a result of your earlier config, whereas thousands of users are using the same flowlessly....
thank you

[Q] "Soft-Brick" when battery removed?

Hi, I have been asked to repair a SGS2 for a friend. The problems he described with it are that it would not turn on, enter recovery or download mode...but would display a battery logo with a circle in it for approx 5seconds with USB power attached. He says this all happened after re-flashing using Kies - he is not very phone / IT literate.
Repair Process:
1) After some research, testing and messing about I made a USB jig for it and it booted into download mode, though only with USB power attached. Connected to ODIN and re-flashed the phone with the stock ICS UK rom (IML74K.XWLP7)...Success the phone accepted the flash no problems, but still had the same non-booting / flashing battery logo only with power error, though it would now go into download mode without the jig.
2) Did more research on here...Thanks to all the useful posts!!! And discovered that the error could be caused by the battery being totally dead, and the phone unable to boot-up enough with USB to be able to charge it - great idea Samsung, to charge the battery you must first power up off the dead battery. Not having or being able to access / borrow a SGS2 myself I decided to try to manually charge the battery by making a charging dock for it. Before charge battery had 3.53v and after 30min on-charge had 3.68v, put freshly charged battery into phone...same problem totally dead unless plugged in then flashing battery logo with USB power.
3) Lots of swearing and cursing at phone, then had a few bottles of Pear Cidre. Decided would be good idea to attack phone again! Took fully charged battery from a HTC Wildfire and for want of better description jump started the SGS2. SGS2 in one hand, Wildfire battery in other and soldering iron in mouth i think, a battery booster was born. Connected booster to SGS2 and without USB power connected turned on phone...Success it lived, finished flashing its self and booted up. Removed booster and phone reported the battery had 98% charge.
4) Passed out in bed... awoke this morning to find phone still on and working well, battery had dropped to 82% in 10h. Decided to bite bullet and turned phone off to see if it will turn back on again and...It did. Repeated process six or seven times through morning as well as using for You Tube and Interned to run battery down, still only got it down to 41%. Though would try my SIM card in to test that all works well and after turning phone off, pulling back off and putting SIM card in without removing battery it all worked great...But then turned phone off, removed SIM and accidentally knocked battery out -D'oh, did not think anything of it until i tried to power back on...dead without power and flashing battery logo with USB power, used battery booster again and phone powered on no problems at all and reports battery power without booster of 29%
Does anybody have any idea whats going on? / Why if the battery is removed from the phone it will not power on at all, even with a charged battery?????
Thank you in advance for your input!

[Q] S3 doesn't charge when phone is turned off

Hello everybody!,
My name is Ferdi and usually if i need help i can find it somewhere on this forum but for this problem I searched the whole internet but couldn't find a thing about it
The problem:
Last week I turned off my S3. it went out for 1 second, suddenly after that the screen turns on again telling me: Downloading, do not turn of target.
So i didn't turn it off because i thought it was actually downloading. it wasn't downloading but it did manage to get my battery empty real quick.
When my battery was empty i tried to charge it at home but it didn't respond to anything (different chargers, connecting it to PC etc.)
I got a new battery thinking my Li-Ion battery had its best time, this new battery did wel and i was able to charge it when it was on.
after i put it off once more it showed the same "Downloading" message again and i pulled out the battery so it wouldn't get empty again.
Tried to reboot a minute later, S3 booted like it was supposed too.
Summary:
The thing is that I can only charge it when it's on.
Does anybody know what I can do to fix it because i turned it off again leaving the battery in it and the battery is now empty and the telephone does not respond to anything anymore.
Thank you very much in advance!
Kind regards,
Ferdi

Thanks for your quick respond,
do you think it is a pure software problem?
the main issue for me is that i can't boot it into download mode even now because it won't charge when it's off and the battery is down.
Charge your battery in an external charger or someone else's S3.
Download a full stock rom from sammobile and flash using odin, follow instructions from 'how to return to stock guide'.
Once stock then test charging function, if still the same then hardware fault - you'll need a service centre.
