[Q] Phone won't boot, can't enter download or recovery - AT&T Samsung Galaxy S II SGH-I777

A few days ago my phone got soaked through my pants as I was working in the rain. I came home, dried it out, etc. and tried to turn it on. Wouldn't turn on, so I started charging it. I eventually got it to turn on and it seemed to be working fine except for some reason it said the battery life was at 0 %. Note that it was still working normally otherwise.
I went into recovery, made a backup, and did a factory reset to see if that would fix the problem. It didn't, so I restored the backup. Now the phone won't turn on at all.
When plugged in, it shows the charging battery symbol, and if you hold power to turn the phone on it will sometimes begin to start, but it gets to the boot animation and simply stays there forever (I've left it at the boot animation for several hours to no effect). If I try to boot into recovery it simply does not work; it will either just restart the battery charging animation or boot normally (and then get stuck on the boot animation).
In a last ditch effort, I was going to try to flash a stock ROM from Heimdall. However, I plugged my phone in and tried to enter download mode and was greeted with the error: "LOW BATTERY!! CAN'T DOWNLOAD!!." This was after charging the phone all night. I then proceeded to charge the phone for another hour then try again, to the same error. And now here I am. It seems the problem is that my phone will charge, and the battery will be full but for some reason the phone doesn't recognize that the battery has a charge, so it just thinks it's at 0%. I've tried a different battery and was unsuccessful. Is there any way that I can either force my phone to enter download mode or somehow get it to recognize the charge on the battery? Or is there some other way I could resolve this? Or is my phone simply gone for good?
I am (was) running a rooted I777 with Slim Bean ROM ( I believe v8) 4.2.

Have you tried using a JIG it can be an option

If a JIG doesn't work you can try removing the battery, then plug the phone to the PC and go to download.
But for me the problem is with the battery. If after flashing the ROM you get the same results, don't think it and BUY A NEW BATTERY.
Good luck.

If I'm bad at English is because I'm from Argentina and I'm learning.

I has the same problema, I spend two days searching on the web, but i didnt have any idea.., ,y problem is. when we conect to ANY charger (car/wall/PC-USB..) appears on screen a batery logo, but the batery never charged..., I tried to enter to the CW but, the keys combination doesnt make anything on the phone, and without live on it, I cant access to CW..., I wait for 2 hrs, with these cell phone conected to charger to see if the it gone works...
ANYONE has another idea for how we resolve these issue? My phone has a stable version of CyanogenMod..

same with me but what i did was put a different battery in, let it charge for a bit then put the original one in and it only started charging after i used my car charger as i was driving to work so thats how i fixed mine.

[Q] HELP!!!!!!!

My Aria was running CM 6.1.1 fine 'till all of a sudden it won't charge.....
Only when it's connected to a charger I'm able to turn it on and it goes straight to Recovery mode. After turning it off and on couple of times i manage to get it work but when i disconnect the charger it turns back off.
What should I do? I don't know what can be the problem. I tried to flash new ROM, including my backups but it didn't help.
Thank you!
did you run your battery completely down to 0%? clockwork has a known bug where if you plug the phone in while its turned off, it will load into a faulty version of clockwork.
i'd recommend leaving the phone plugged in, let clockwork show up, hit reboot now, and just leave it plugged in to see if it maintains a charge.
Hey,
Ive tried it. it won't charge and even if it does, the battery lasts for an hour or so ...
So the problem is with my battery?

[Q] Tried extra battery, now Note won't work?

I bought the Anker charger/2 batteries set in this thread awhile back - http://forum.xda-developers.com/showthread.php?t=1632718
Had not used them before, but hurricane Sandy is coming through so I figured I would test them out. I put one in the charger last night and put it in the phone this morning, and now the phone will not boot up all the way - it shows the Samsung bootscreen, then the KingKangers logo screen, and then shuts off. I've had this same issue with both of the new batteries along with my original Samsung battery.
I have tried to put it into recovery and download mode, at one point it showed the download mode screen and then shut off again. Recovery mode has not worked at all. Tried holding power for 30 seconds while both plugged in and not plugged in, no luck. Saw a recommendation to take out SIM, SD card, and battery for 10 mins and then put them back, and that didn't work as well. Tried to see if ODIN would "wake it up", but ODIN does not recognize it (tried two cables from two different computers). Computer also doesn't recognize my phone to look at my files, etc.
Also, when I plug it in to charge with the battery in place, it does small vibrations - I have noticed this is the same thing the phone does if I plug it in to charge it without a battery in...worried this may mean my phone is not recognizing the battery for some reason??
Any ideas? Any help is MUCH appreciated...
FWIW, running AOKP and Dagr8's KingKangers kernel, been running it for the last week or so with no real issues other than occasional reboot.

[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] My phone doesn't turn on or charge

Hi everyone
Last night before I slept, I charged my phone. After I woke up and unplugged the charger, my phone did restart by itself. Then it just turned off. When I tried to remove the battery off and put it back again, the phone tried to turn itself on but it stuck and vibrated like when it was being charged without the battery. I also try to put in the battery and charge but it was still the same (tried to turn on itself but fail). It is still the same again when I connect my phone to the computer. It just went like when I try to charge. Now when i put the battery back to the phone, it tries to turn on itself and then goes error.
The phone actually warned me about the damage before. My internet browser bounced off when I used it. Well, I actually remain 2 browsers because I can;t get the rid of the original one.
My issue is kind of stupid because i have searched similar threads on this forum but they are not like exact my issue, :crying::crying:
Is this a guessing game?
Ok, RR ROM using speedmod.
I9100.
How did I do?

When my galaxy player has the same symptoms, it means there is a kernel error, just reflash the stock firmware for your phone and go from there.

[Q] HELP-Razr wont boot - OMAPflash?

Hey guys,
unfortunately my 3-year old Razr died the other day. Battery has been an issue for the past few months where I had the battery completely drained 2 times but always got the device back to work. This time it's different though.
I shut down the Phone at aprox. 20% Battery to safe it from low charge. I have NEVER flashed a custom rom, the phone is purely stock. The phone wouldn't turn on the next time i tried. Initially , I had zero reaction. Then, I got at least the white LED when charging with the original adapter. Let it charge a few days. The white light would turn off after a few hours but the phone is still dead.
I replaced the battery with another (new) EB20 but still nothing. I bought a wall charger (1A) and still nothing. I even tried direct charging the battery for a few hours and still no effect. Also, every combination of Power+Volume buttons didnt work.
So i bought a factory cable but still didnt get any reaction. When hooked up to a computer via USB i have a "connecting" and "disconnecting" sound. Once the device was detected as OMAP 3340 but couldnt install it. The problem is that I dont even get the phone into fastboot mode.
On my research, I found these posts:
http://forum.xda-developers.com/showthread.php?t=2055839
http://forum.xda-developers.com/showthread.php?t=2047750
I think this will be my last try and option, but i have no experience whatsoever with flashing and I find the description very hard to understand and follow. Is there maybe someone who can explain step by step what there is to install/do and in what order? This would be awesome.
Greets,
razore
