not able to reboot device - Redmi Note 2 Q&A, Help & Troubleshooting

When I try to reboot my RN2, it show me the boot logo/animation but after it, it shut down, doen't matter how high is my battery percentage. The only thing, how you get it back to work after this is, when you plug it in for charging while booting, after it, you can plug it out again. Maybe my new "orginal" battery is the problem for that, but I don't now, everything all is fine.
Thanks

im using CM13 rom and having the same problem as yours, just when the battery's lower than 15%
any idea ?

[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] S2 won't boot after battery depletion

Hi,
Few days ago I forgot to reload the battery. Now that I try to bootup the gt-9100 it only shows battery logo with loading sign. It won't react to any button presses, so i can't get to download mode or to recovery mode.
I flashed CyanogenMod 9 Nightly a week ago. It worked like charm until now.
Does some one here have any kind of suggestions I could try?
Thanks..
How can you be sure that the battery has enough energy to boot the phone as you can still see that it is charging? Eventually the battery should be reported as fully charged.
when it depleted i connected it to charger and left it there to a whole night.
it should have enough charge.
just tested some some key combinations and i got good results. when i push vol down + home + power before i put battery back to the phone, i get to the odin mode.
now i have to find usb cable somewhere.
I got it flash new rom to it. First time the problem still persisted.
After trying some new button combinations and after flashing cmw i got it boot up.
Few seconds after fully booted, it powered off and i got same battery logo that does nothing. I'm starting to wonder that the problem is somewhere in the battery or the battery charger system.
Yes, might be a problem of the battery or the charger. If possible you should first try this battery in another phone and/or another battery in your phone.
If you have the possibility to charge the battery outside the phone that too would we worth to try.
For me it looks like your battery is empty but I might be wrong.
Flashed it again with a samsung stock rom. Now its staying alive.
Now it notifies me every few minutes that "Charging paused. Voltage too high.".
The phone is not currently connected to charger.
My guess is that the battery has gone bad. Unfortunately i don't have any other batteries or phones that i could test.
I think i have to go and buy a new battery.

Actually, this sounds like the port may be bad. You could try cleaning it... But you'll probably have to replace it.

[Q] Xperia X10 troubleshoot near brick situation

My phone is acting weirdly since past few days. I am currently on Feralab GB rom.
Firstly, the phone would automatically restart and battery level would fall by nearly 20% every time.
This leads the battery level to drop down to zero. After that it wont start and wont go into flash mode.
After some time(1-2 days), i tried booting it and it got to the main OS but as battery was 0%, phone automatically turned off.
Afterwards, it behaved normally for few hours. But it again stopped working just now.
What could be the problem ? Any ideas ?
P.S. When the phone turns off by itself, nothing works on it. Not even SEUS.
you could charge the battery with an external charger, or desktop charger something like that, i mean unattached in phone ... make it full
then put it back to phone then install other rom like DonutHD ... the battery performance on it is good, then if you face the same problem it should be a battery problem ... you should change it and buy a new one then

I know it is not a battery problem. Because it wont work with other batteries too when it automatically shuts down.
so ... you couldnt install any other rom because of that problem, tried and failed ??
maybe then its a hardware problem in the phone

Boot Loop

I was running a 4.2.2 ROM...well, I was switching between two of them.
My phone started doing some massive reboots today, so I decided to reflash.
Now, if my phone is NOT plugged to charge, it boot loops. Gets up to the boot animation, then starts all over again.
If I plug the USB cable in and boot the phone, it boots all the way and the phone is fine.
HOWEVER, as soon as I unplug the cable, phone reboots again. Battery charge is full.
Running TWRP 2.4.4.0, and was flipping between JamieD's 4.2.2 and ManelScout's Vanilla, along with Ace's latest kernal and the UCMB4 modem.
Trying to determine if this might be a hardware problem. The OS is showing as battery full charge, but recovery shows battery % @ like 2%.
sounds like you may have a stuck power button

I read that in someone else's post. Physically, it seem like the power button is fine.
How do I "unstuck" the power button in this case?
I've already ODIN'd to stock GB, and downloading the ICS update. Pains me to be unrooted and on a stock ROM.
I need my phone operational ASAP, so I am struggling right now to get this thing functioning normally?
Do I need to take it apart? Is the power button "stuck" in the sense of software? Or literally physically?
BTW, the power button is responsive in terms of turning the unit on/off. Does that still mean it is stuck?
And what about the fact that the unit will boot up fully with the power plugged in, but boot loop if on battery only?
Try another battery. Yours may be going bad.

[Q] Phone won't boot, can't enter download or recovery

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.
