Galaxy mega 2 issue - Samsung Galaxy Mega

Hey, so what happened was I tried to root my SM G750, it went bad. Long story short, I flashed stock ROM, and lost all my data . My question is that since I flashed the stock ROM back on, I have this weird issue that if I charge it, the screen goes off and the red LED light comes on (like it should).. The issue is that after a while the screen can't be turned on and to turn the phone back on, I need to take out my battery and turn it on. What do you guys think? (I haven't really tried anything yet)

[Q] Phone is dead, can't turn it on, bricked?

Hi guys,
My Galaxy S2 will not respond, will not power on at all.
I put it on AC charger before I went to bed (like I been doing for a year) and in the morning I was not able to power the beast on.
The phone is rooted, it's on 2.3.4 stock, 8 moths ago I flashed an insecure kernel so I can use BLN, I had the yellow triangle for about 3 weeks and then it suddenly disappeared. Since then I been using the phone with no problem, I haven't made any other software "adjustments".
I tried another charger, I tried other battery, I tried Download mode, Recovery mode, computer USB, nothing works...
What could have happen? I haven't installed any apps lately either.
I forgot, once every like 4 weeks the phone randomly shuts off and will start vibrating, and it's unresponsive until I remove the battery and power it back on.
THANKS

Be aware that you will lose 2GB of internal space.
Thanks
So I had a bug in my phone? How? I never had ICS ROM.
If I buy a screen broken SGS2 and take the motherboard from it will work? I mean it's compatible with camera , mic, sensors , etc?

Sounds like it needs a trip to a Samsung service centre.
Yes has to be sent back samsung/warranty, but first he has to get rid of the custom ROM somehow...
Sounds like another sudden death case.
Don't worry about custom ROM if phone is dead Samsung have no way of knowing, they'll just replace the mobo

This happened to my S3, and i wasn't able to open it for 1 day.

-but cant turn on
i tried to pushed a bit hard the on/off button for many times. and BoooooOM!
i was thinking that the problem was on/off button contact.
well, u can try. but if not. better to send it to samsung
thank you all for your responses .. i guess i'll send it to samsung

[Q] S3 not turning on

yesterday the battery of my s3 was very low (around 2%) and i went to sleep without charging it. When i woke up after about 4 hours or so the phone was dead. I plugged it to wall charger but nothing changed i mean there was no battery sign or LED light. I thought the battery is completely drained so i left it there for about 15 min. When i checked again there was still nothing. I tried to turn in on but no response, unplugged the charger took out the battery then put it in , still no response. so i just left it there to charge for half about half an hour. Then i tried to turn it on again but still nothing. I tried recovery mode but no response. then i tried download mode and it did got to download mode. Now i thought it was OK so i restarted the phone but again it wont respond (Black Screen). I tried the download mode again(wall charger was plugged in the whole time). The phone did go to download mode but the screen started to Flicker and when i restarted it the boot screen(I-9300) turned up(still a little flickerish). and then it stuck there for a while. Then it went black. Again i left it to charge for about another half an hour. Now when i tried to turn it on, recovery mode or download mode Nothing happened, there was no response.
Then i started reading different threads on internet but couldnt seem to find anyone else with similar problem. Btw i checked the charger on Note and it was charging fine. then i tried to charge my s3 through laptop and the battery sign appeared and phone started to charge. I turned it after a while and it turned on Ok.
My phone is rooted , custom rom -Omega 39 with Custom Kernel Yank555 and Philz Recovery v4
Now my question is, Is there something wrong with my set? i mean the non responsive state and screen flickering. Should i get it checked or was it something that just sort of happens. Has anybody else faced a similar problem?. what can i do to avoid it in the future.
*Sorry for such a long post, its my first time. and i read about the S3 Sudden Death and now i am freaking out!..

I know this sounds silly but its not in "hardsleep" as some people would call it, where the phone is idle for too long and basically shuts its self down? Or it could be the sudden death issue associated with the s3. This probably isn't much help but its a suggestion, I've never come across this before

Try a different charger and cable. The s3 ones are notoriously crap.

It's been a known issue since the S3 was released. You've been lucky

After i turn on mobile data/wifi phone goes crazy

Hello guys!
I need help with my mobile phone. I bought it year and a half ago, and have changed operating systems few times (custom roms). Now I have Pristine JB Slim custom ROM, i have installed it 1-2 months ago (cant remember exactly), and everything was okay for first half period, but then it started to crush after mobile data/wifi was turned on.
When I turn on MD/WIFi, its usually okay till 76% of battery, but then screen starts to blink for few seconds and turns off immediately after. When I turn it on again, it turns off again after 1-2 minutes, and sometimes even warns me that i have to charge it cause battery has only few % left (most of time just 1). And I have to charge it again to work normally (well, until it starts to go crazy again )
I dont know whats going on, I wanted your help before i start to install other roms again. So.... what do you think? Is it faulty battery, bad ROM or something else?
I think it's the ROM's fault so try flashing a stock ROM and see if the problem is solved
