Phone won't boot - Samsung Epic 4G Touch

My brother-in-law's SG2 won't boot. All it will do is show the "Samsung Galaxy SII" logo, then show the battery charging. If unplugged, the blue LED faintly lights then the phone does nothing. When plugged in, it shows the battery at 100% but the OS still won't boot. I got it into download mode and Odin'ed Rwilco's stock ROM to try and restore the system. Odin showed that it "Passed" but the phone still won't boot. I even got it into recovery mode, and tried a factory/data reset, but no change.
I heard that the phone has had battery issues, and I tried the spinning it on the table trick. It doesn't spin at all, so I don't think it's bulging... but is it possible that if the battery is dead that the phone would not boot, even if plugged in? Or is the problem even greater?
Has anyone experienced anything like this before?
FWIW, he's on Sprint. (I'm a VZW user)
Nothing had been done to the phone (before he asked me to look at it )
Thanks in advance for any help you can provide!

Have you flashed the matching/compatible kernel for that rom as well? It's been a while since I have worked on one of these phones, but I do remember having to flash the compatible rom and kernel separately from one another otherwise it would cause the phone to boot loop or freeze on boot. If you are running the stock recovery, you may try flashing a kernel with a custom recovery then from recovery use the option to reboot into system. I don't know how that would really make a difference but nothing to lose if nothing else is working.

[Q] Galaxy Nexus won't turn on after attempting a flash stock + Unroot???

So I'm not sure what happened with my girlfriend's Gnex, she updated to 4.2 a couple days ago, then her battery died. So she went to charge it and when it finished charging, she went to turn it on normally, but it went into a reboot loop? So i was talking to someone else on another thread that i saw similar, so i tried to do a flash stock + unroot, it connected i got into recovery menu and everything, went to do it, and then the screen started going staticy, and it said it failed then it said it should take 5-10 minutes or something. So i guess it froze or something, so i took the battery out and the screen was still staticy, and then i unplugged it from the USB, and now it won't turn back on. Did i brick the device? :/ Thanks in advance for future answers.
you cant get into to recovery either? or fastboot mode?

I'm having a similar issue. I wanted to flash the memory so i relocked the phone using the wugkit, then unlocked and rooted. For some reason, it wouldn't load a new rom. I kept getting the triangle exclamation point android graphic. I pulled the battery and that was it. Black screen. Won't turn on. A cpl of times, it was almost recognized by the computer via USB, but just kept failing. This sucks.

Yes the battery is charged. Occassionally, when I plug it into the computer, it makes the new device notification and then fails over and over again. I keep trying to get a glimpse of a lock so i can adb it.

[Q] Can't boot to recovery or download mode

It is a long story, started with wanting Photoshare App. After rooting using Odin got into all sort of process stopped error. Desperate, downloaded and tried to flash CM10 using CWM. All I got was CM logo circling endlessly for 30 minutes. Pulled the plug and now, I seem to have a brick, can't even boot to recovery or download mode. When I try to boot to downlad mode, the warning screen appears for just a second and goes away. When I try recovery mode Samsumg log appears and then blank.
Is there anything I can do at this point? I appreciate any help I can get.

Hm. if you boot up your phone are you stuck at the cm bootup? If you are im sorry bro you cant fix it for free by sending it to samsung. JTAG for 60 bucks or samsung for 60 bucks. Reason being that it shows that you have rooted and modded your device. If you were hardbricked and nothing would turn on at all you would be able to send it to samsung and get it fixed for free!
Well if it shows Download mode then it might be working, just not showing, if you see a blue ID:COM number in Odin its working. Try to flash a stock ROM in Odin while in Download mode and make sure its in PDA or you will brick. Check only Auto-Reboot and F. Reset time.
If it works congrats if not search this forum for a service called JTAG which repairs bricks.

A little update ...
I was able to get to download mode after many trys and got back to stock -- unrooted. I should have stopped when I was ahead, but I was feeling invincible after this feat of reviving the phone and that was really stupid.
I wanted to root and flash CM10 nightly. I followed the instructions from http://rootzwiki.com/topic/32486-gu...m10-nightlies-without-k-exec-updated-8-18-12/. After unlocking the bootloader step, I wanted to backup the stock ROM I had on the phone -- I don't know why I wanted to do that as I had just flashed the stock and didn't have anything customized. Anyway, when I clicked backup from CWM everything died, kaput, nothing. I have been desperately holding the power button, reovery combination of buttons, download mode combination, anything I can think of, the phone is giving me the total silent treatment, which BTW I am used from a more human source.
Let me know if there is anything I can do, perhaps stand on one leg and try switching it on perhaps. http://forum.xda-developers.com/images/smilies/redface.gif
Sorry for the dumb jokes, I am a little frustrated, but I am sure I will get over it.
Thanks for those who took interest to read my question and those who cared to respond, I appreciate it....
Cheers!

[Q] Soft Bricked GS3 with CM10.1 Update

So I recently updated my GS3 to the nightly 8/12/13 build am I am unable to boot my phone into anything except download mode. When booting recovery it says the blue text, shows Galaxy S3 for a second, then crashes to the recharging icon. I've tried flashing a stock MD4 rooted nodata and a stock recovery through Odin, which pass and return no results. Please help me fix this!!!
It rebooted a couple times once and I got the stock recharging battery, not the blue one but the green one. But other than that there's no signs of change.

QBKing's site is down, here's an even more in depth explanation of my problem:
I cannot boot past the Sprint Galaxy S3 logo. When it does boot past this, it boots into a battery charging mode, either a blue battery with static circle, or a green touchwiz battery.
I have flashed stock and custom roms without any results, when odin reboots, it simply flashes the galaxy s3 spashscreen again and goes to the battery charging icon. This is true no matter what I do, including entering recovery with the home, power and volume up buttons.
I've tried QBKings tutorials, but in this case without downloads they are not useful. I've tried quite a bit of stuff and I'm not worried about losing data at this point.
I found the link on QBKing's website, so hopefully this will work, I'll update again once I flash.
EDIT: Didn't work after following instructions completely, just stuck in vibrate loop afterwards, and after power cycling it's back to the same thing.
The red light lights up right after I plug it in, and I am unable to run or turn on the phone using battery power, even with a full battery.
Another thing I find exceptionally strange is that it boots into the charging mode, even after trying to enter recovery. The batteries mean nothing at this point and I really don't know what to do.

Hey man, I soft bricked my phone as well. Not with CM but by doing a factory reset on the phone when it was rooted. Im stuck on Galaxy S III screen as well and a vibrate loop. I've tried to unroot/unbrick also but to no avail. Any help anyone?
I just took it to Sprint and it fixed. Not sure what they did.

T999 Won't boot/start

Didn't find anything similar on here so I had to post. My T999 no longer boots except for a vibrate when the battery is removed and re-inserted. Occasionally it will get to the CM boot logo and then the screen goes off. If I time the button presses right, I get to the Download screen but before I can hit the Up button to confirm download mode the screen shuts off. This happened all of a sudden yesterday, the last activity being to shut off the Alarm. Tried charging but it will not get past the initial battery icon before the screen goes off. Tried replacing the battery but that didn't help. I also tried to follow the debrick instructions but it didn't help. I was running Vanir AOSP 4.4.4 with no issues until yesterday. The device does not register when connected to the PC using USB and the charger LED does not light up when plugged into charger/PC. My feeling is that something went wrong with the boot but I am unable to get into any usable screen to do anything. I had managed to brick a Samsung Vibrant before but I didn't have to struggle as much to debrick and ODIN back to stock. Any help would be greatly appreciated, I'm now without a phone .
Mine is also acting like that. It wont boot to any rom even stock ones. But i noticed that if i connect my charger it will boot to the homescreen. Sounds like a battery issue right? I also thought that but when i go to recovery, it did not shutdown after leaving it for a couple of minutes. I'm also baffled why it wont boot. I'll try to borrow other battery to test if it still the same.

Remove battery snd put back in. Does the device try to turn on by itself? If so you probably have a bad power button.

Done this using root66 but still the same. Now my phone went to worse. It wont get past the S3 logo in the boot screen and just shuts down followed by a vibrate. But if i connect my charger, it will continue and run as normal. My suspect might be a bad battery but the thing is it doesn't auto shutdown when is download mode or in recovery mode. Will try to borrow other battery and update if this fixes the problem.
This is pretty strange. Woke up to my phone with the Galaxy s3 boot logo. And it wouldn't go past it. Tried flashing different backups I had but none of them let me go past the boot logo. Flashed CM10 since my version of TWRP recovery is so old that it can't flash anything higher up, and it goes past the boot logo finally after 2 hours then goes to the cyanogen boot logo but doesn't go past that. I'm going to try with ODIN tonight.
Seems very strange that there are others that had this happen to them to. My phone has never done this before, and it happened randomly.
What does it mean if my phone doesn't boot past the logo with an odin to root66 file?
Edit: Nevermind seems to have worked... for now.
Edit 2: Okay so now it's stuck in an infinite loop where it boots past the logo, shows the android mascot then does an android is upgrading app 1 of 169 then goes back all over again. This is fun! Can anyone help?
Edit 3: Okay so I had to do a factory reset. Got it working now. Starting to get sick of the things I have to do to get updated firmware. Samsung needs to get their crap together!

Hopefully its just the battery.
Download mode may work because of how the battery reports to the os. If its going bad and reporting incorrectly that its low, it may trigger a shutdown. Whereas in download mode the os isn't running so its not reading the battery info the same way. Just a guess.

Just for future reference, factory resetting solves about 98% of boot hangs.
Still for both of you, id take this as a sign that you should make sure your backups are up to date. If something is failing you'll be glad you did!

Yeah factory reset unfortunately didn't work for me when I needed it before I had to ODIN to root66. But I was able to do a nandroid after I couldn't get it to boot and extract my sms from Titanium backup. What an awesome app, super thankful to that dev for making it.

Turns out it was the battery sir. I've tested it with another battery from 2 different phones and it worked fine. While the phone i tested with the defective battery didn't event get passed the samsung logo. I've suspected it might be having the low voltage causing the phone to shut down.
Anyways, after that i bought a new battery immediately and everything seems ok. thanks for the reply doc.

I can confirm that it is likely a bad power button, I have tried everything including dismantling it and seeing if I could dislodge any dirt that may be causing the problem but it didn't work. Looks like I have to find a local repair shop or ebay to get it resolved. Anyone recommend a good place to get this fixed. Funds are limited
Im not sure exactly how difficult the repair is most people seem so do it themselves and have given indications that its pretty easy. You can find the part online for a few bucks.

[Q] Random Reboot Leads to Bootloop from...

OK all I am sincerely reaching out as I am out of ideas. Here is the situation...
Issue : Last evening, running most recent Liquid Smooth 4.4 (Superb ROM, I don't feel this is really at fault just relevant and thorough), I had been doing some heavy tethering when I picked up my beast and stepped out for a smoke. As I am reading up on moto360's 2 1/2 hour sellout I get a random reboot. Eh, no biggy ... it does happen. (Not often, or at all to speak of in my case just stating.) Right after reboot I hit the power button to make a forced boot cycle and it rebooted again before I pressed anything on screen!
Now SOMETIMES I will boot past the initial "NOTE II" splash (NOT often at all ... usually get reboots, splash hangs, or the phone simply turns off on its own from here) If it does make it past Note II splash it will reboot, hang, or simply turn off from here as well.
Steps Taken: I firstly, attempted a restore... no dice. I attempted a fresh install (TW, SlimRom, and DU) ... no dice dos. OK hmmmm
Now to all mighty ODIN (L900VPUCNE2_L900SPTCNE2_1561791_REV04) .... NO FREAKING DICE!!! WTF?!?!? I additionally attempted MC2_STOCK_with_COUNT_RESET-20130511 ... no bueno!
I still have access to Recovery and Download soooooooo ... I lay down at the mercy of you the community!!!
Thanks in advance and if you need more info PLEASE don't be shy!
Same issue here!!!
After a random reboot, I have the same type issue!
Running an almost stock NE2 rom, random reboot then hanging at the Note2 bootscreen.
Like you, I can access download and PhilZ recovery.
I CANNOT flash through recovery. Errors out.
Odin flashes succeed but on reboot I still hang at the Note2 bootscreen.
My recovery is showing multiple error related to accessing E:, E:/cache, etc.
Are you having that issue as well??
Try this go to samsung-updates.com
search device l900 scroll to the very bottom of the list
download the L900VPUCNE2 zip (this is a pure sprint rom)
flash using ODIN3 v3.09
I have flashed this file many times and it works every time.
Hope this Helps.
Exact same thing
I've been running the latest nightlies of OmniRom. And yesterday, out of the blue, random reset then bootloop. No luck with anything, recovery, odin, etc.
Did Sprint deliberately brick our phones?
I'll try the odin to stock to see if I get any luck there. But if anyone else figures it out, it'd be nice to know the fix. Thanks!
No luck going back to stock. It's dead Jim.
I had a very similar issue. Try booting your phone with it plugged into the wall changer; something given the full 2amps of power. It it'll boot, it's possible your battery is bad.
If my case, my phone would boot loop around the splash screen. on the battery power only. I could go into recovery and download mode with no issues and stay on for hours. If I connected it to, say a PC, it would boot, but would random shut off within five minutes. But if I plugged into the wall charger, it would boot with no problems. Stay on for hours. If I plugged it from the charger, it would immediately shut off and try rebooting which it would just boot loop.
Luckily, the batteries are pretty cheap at $10 to $20 on Amazon. I went with the Anker for $15 to get me by till I get my next phone, which will probably be October; I'm heavily learning towards the Note 4
Replace the battery
I had the exact same issues. I ended up buying a $10 battery on amazon and it solved the problem. I did go through all the flashing, odin to stock, etc. All was pretty good when plugged in to a good power source. It took me about 4 hours of trial, error, reflashing, etc before I realized it was probably a battery issue. The new battery has solved the problem.

I couldn't flash any of counter reset rom through anything but TWP so i have to boot into download and update away from Philz. AFTER the recovery update I started making headway. but couldn't ever seem to make it past boot no matter how much batter is charged. I was beginning to think it was something that died on the inside (heh...heh)
After reading through some of these greatly appreciated replies I am going to plug her up to the wall and try the ne2 counter reset again(12:58 am). ... AND I may go throw some cash at a battery juuuuuust in case. (I do tether 100gigs daily sooooooo it does make sense that it could have burnted up lmao!)
UPDATE 1:25AM : I did as advised and it does seem battery has taken a dive! hmmm so weird! It still shows having power and charging. But after being plugged into wall I made it booted into a fresh ODIN install!!! (keep in mind that AS SOON AS odin gave me a pass I switched to Wall outlet!) I have even performed a power cycle to confirm it wasn't a fluke! I will indeed be out first thing in the morn to get a new battery!
AGAIN I can not thank you all enough ... I would have never thought of that. (you would think it would be one of the first things but eh you live and learn.)
I will update with any new progress!
cheers!

Mine does the same and hangs .... right? HIt the power button and as soon as it lights up to start to boot then plug in the power cable. (the freezing while off and charging is a known bug in at least two roms i believe)
Congrats Rubledub!
As for me, I'm still screwed. Invested $40 in a battery (had to have it today, couldn't wait on shipping)
With the new battery fully charged I still have the same result!

There were probably signs of the battery going bad, but misread. But in my experience, it went to total crap instantly.
The signs of going bad were shorter battery life, getting stuck/freezing when trying to charge the phone when off (there's that battery graphic that shows up). Unfortunately, I did all kids of other stuff before I really figured it out, and looks like a messed up my modem and now cannot connect to 3G. Kind of irritating, but luckily, I spend 75% of my time in LTE areas. Just got to ride this out till the Note 4 is released.
Here is thread of when I was having trouble: linky/URL]. It's a lot of me trying slightly different things with no changes in results. Plus, I was a buddy's house who was in a 3G only area. The worse part, my phone did this the day before I left to spend the weekend five hundred miles away from home at a friend's house to visit.

Oh i agree! Thats is what had me so baffled ... Not even the odin installs were breathing life, and Odin ALWAYS works for me. If Odin isnt getting it done and neither is a battery then your problem may be far more serious???
Weird Recovery Lag and bootlooping after CM12 update
Hey guys,
I came across this thread and the issues I'm having sound so what similar, so I thought you might be able to help.
I have two Samsung Note 2(l900) and running on cm12 as of yesterday morning. I installed the new nightly manually on both devices the same exact way by opening clockwork recovery and installing zip. One device was successful and is working just fine, the other seemed to flash fine until it had finished loading the apps and going into boot. The device would restart on the note 2 logo screen and then proceed to the cm12 boot screen and then restart after a few seconds. I went back into recovery which took longer than usual, and proceeded to clear partition, wipe dalvik cache, and install older nightlies. I had the same result no matter what nightly I went with.
I decided to set the device back to stock rom and root again. I it worked just fine, so I went through the process about 4 times installing different nightlies but had the same restarting results. It was then I noticed that getting in clockwork recovery manually lagged about 30 seconds. I took the advice of someone on the Google plus forum and switched the recovery from clockwork to twrp. Tried again with the same restarting results and with the manual recovery lagging about 30 seconds to get into.
I'm back on stock rom and the device is working great but takes forever to get into manual recovery which I believe is why it is having issues booting Cm 12
