[Q] boot loop phenomen - Galaxy Note II Q&A, Help & Troubleshooting

hi!
suddenly my n7100 does reboots again, and again.
on start with the n7100 logo - while charging, the bat icon, it reboots - i can not go even into download mode.
if i disconnect the bat power, and leave it for 1 or 2 days it is working again, a few seconds.
i flashed new rom, wiped cache, and new recovery. sadly: no success. still in a boot loop.
i have looked in the internet and of course in this forum - does anyone know what to do, to get it alive again (well it is, but it is rebooting(((?
is the board broke? or the switch ( it is working as far as i see) - or some ram?
any help would make me glad
tia,
rasp

I guess it's not working when charger is connected ? So I understand from your post.?
Also which bootloader are you on? And which rom you flashed?
If you using kitkat notice that the bootloader is better to be the one from the kitkat rom.
Or do you used rom with Ultra saving mode the first time you got those bootloops.

So you're saying your phone reboots by itself as soon as you put the battery inside? Can you get into download mode without pressing the power button just press volume down + home button if download mode opens up that means your power button is messed up (either it's pressed all the time or you need a new power button)

[Q] Note 2 dead after root

Hi
This is my first post. I have had Note 2 for 6 months now and have done a root using Samsung Galaxy Tool kit which worked fine.
Few days ago, I update the phone updated which unrooted the phone so decided to root the phone again last night.
It went through fine and the phone was working. I was able to use all the apps and make calls. This morning after making a call, I put the phone on the desk, after 10 minutes, the phone was dead. I couldn't turn it on.
Battery was fully charged. when I press the power button, there is a red light on top flashing.
I have tried vol up + home button + power but it doesn't work.
I have looked at other forums but no real answer to the problem.
I was going to flash the phone with original stock rom using Odin, not sure if it will.work
Please advice there is any other solution to this.
Thanks

Sounds like sudden death.
Sent from my GT-N7100 using xda premium
How you will flash ROM? you are able to reboot to download mod?
If yes, try it
Symptoms are highly suggestive of sudden death.
If you are unable to flash ROM, don't do anything and send it to service station.
Well have you taken out the battery yet? If not, please do and leave it out for 1-2 minutes. Then put it back and see if it boots.

no I can't boot the device hence can't flash. you are probably right, "sudden death" as I can't do anything except the red light next to the ear phone flashing every 10 secs.
Yeah that is proximity sensor light and that is classic symptom of sudden death.
Can you tell me you were on which rom last?
I mean you have updated to which rom, bcoz latest rom believed to be fixed for sudden death. And that will be big challenge if you were on ll7 and still it is sudden death.

I wont be able to flash any rom as Galaxy Note 2 tool kit cannot connect to the phone even though all the drivers are installed.
The phone need to be in either recovery mode or need to be on to flash ( unless I am mistaken)
And in what circumstances appear???

Don't worry in sudden complete death (unable to get into Download Mode) they can't figure it out.
Just ask him it was as it is after purchase and it happened suddenly. Do need to even mention you can't boot into recovery or download mode.

HTC One X Dead after CM Update

Hey guys,
about 8 or 9 hours ago I updated to 20140209 Nightly via CM Updater.
Everything went fine, phone booted as usual. But then after some minutes of using the phone started lagging got warm around the camera and the screen froze.
After that I pressed and held the power button until the phone rebooted.
Then things went weird. The phone seemed to crash while booting about 3-4 times.
Some times while the CM Boot logo was there, sometimes when the HTC logo what there.
And then the screen went black, Battery LED went off and the phone seems dead.
I cant get it back on. ADB doesn't work. Holding Power Button doesn't work.
And every other button combination (like Power+Vol. Down for 2min) doesn't work.
The phone was plugged into the wall charger for about 7 hours now and still not a single reaction.
Not even the PC gets any connection so its not APX I think.
Is there any way to fix this ?

Seems like the phone is completely dead.
I don't think it's software related.
I cant even boot into bootloader or recovery.
The phone simply doesn't do anything. :/

BootLoop post Viper4Android module on Magisk with Lineage 15/Oreo

Lineage /Oreo was installed thru TWRP 3.xxx, running fine but unhappy , no Viper4Android , so I installed it as a module on Magisk,
after installing the driver, was ask to reboot as directed, but went into bootloop , stuck on a boot loop " Set Warranty Bit : kernel " top left corner and Samsung Galaxy Note 3 on screen ; I tried Vol Up +Home+ power combo and all other combi I could think but no luck , Odin wont recognize my phone, tried Samsung 300k tool with no luck, I fell like a newbie after using so many ROMs on all of my devices, I google how to get back to download mode but no luck, I need help to make my Samsung note 3 work again, PLEASE. THANKS.
Hi,
I have same phone but I'm running Resurrection Remix 6 which is based on LineageOS 15.1 and I'm able to use the Viper module through Magisk 16.3 without any problems. No bootloops, no nothing.
I never would have guessed that a sound mod could brick the device to the point that the buttons no longer function. Hopefully other users will chime in and help you fix it.
Best of luck.
EDIT: Try taking the battery out to force it to shut down and then try the recovery/download mode technique again. Sometimes, it'll end up in a bootloop and the buttons will be become unresponsive. I know it may seem a bit strange, but that scenario is entirely possible given the age of the device.

I did tried RR 6, but I had trouble with 1.) power Button menu option, screenshot/screen record , 2.) Viper4Android , a must have on all my Android devices, and last 3.) latest Android version , if I dont get the first 2 obsession , that's when I switched to a different ROM (LOL), but seriously , all I need is to get HELP to get back to download mode again, Vol Up + Home + Power, did that for 2 days approaching the 3rd day (LOL). HEEEELLLLLPPPPPPP.
Isn't download mode volume down + home + power?

You need to take the battery out to force it out of the bootloop then push volume DOWN, home & power.

The jig that I bought didnt do anything so I make my own, I can go to download mode now, installed this ROM/firmware N900TUVUCNB4_N900TTMBCNB4_N900TUVUCNB4_HOME.tar.md5 succesfully but wont go pass beyond the tmobile logo, tried a few more firmware and lately this N900TUVUFOL1 and also , am stuck to Tmobile logo, anybody knows which firmware would likely bring my note 3 back to life, thanks in advance.:
Try this:
Uncheck everything in Odin except f reset time. Flash the latest ROM again. When you see the word "reset" in the status WIndow, remove the USB cable from the phone, remove the battery, replace battery, boot into recovery mode using buttons, factory wipe, and reboot.

After "reset" status, I did remove cable, remove batt and boot up to recovery, the blue light lit up as if its going to recovery mode , android logo showed up but phone boot up to normal but not pass beyond tmobile logo, so I did CF-root via odin , but still not booting to recovery.
Try flashing the entire ROM in AP.

I manage to restore my Note 3 to TMobile Android 5 using repair firmware , it looks like I wipe out the partition ,My phone runs like new, am just wondering why I cant go to Download mode with button combinations of Volume -/Home/power , tried to install twrp via Odin, it says PASS but Vol +/Home/Power wont lead me to bootloader, did tried CWM , it will boot up but before I could start using it, it will reboot to normal and I could not go back to bootloader with button combo Vol+/Home/Power........HELP...
Download mode is volume down+home+power.
To flash TWRP with Odin, try this:
Open Odin and only check f reset time. Flash TWRP. When you see the word reset in the Odin status window, remove the USB cable from the phone, remove the battery, replace battery, press home + volume up + power.
N900TUVUFOB6_N900TTMBFOB6_TMB and N900 PIT - are the files am using after screwing up my partition( I dont know how I did that ), this Note 3 is running like a hot knife on a butter BUT the only bug I notice is Volume Up + Home + Power ( recovery) NOR Volume Down + Home + Power (download ) does not work, I can only go to download mode using a USB JIG and no other way. I can flash TWRP via Odin with Auto-reboot not ticked , so I could remove cable, battery , hoping to get me to recovery mode but I couldnt. Did I miss a step?I need help.

Galaxy A50 no longer booting.

Good evening All, It's been a long time since I last posted but want to start at custom roms again and I'm hoping someone can help me as I am now considering giving up on this device.
My sister-in-law gave me her old Galaxy A50 after it stopped working, gives the circle with lightning icon but not the normal charge notification. If it boots I just get the Samsung A50 start screen but no boot and no boot animation.
I have cleared cache, factory reset and tried flashing stock roms via Odin as the bootloader is currently locked so no custom ROM's for me to play with yet. I have tried a couple of stock roms but no joy.
The questions I have are below:
1, could a faulty battery cause the phone to not boot?
2, Is there a way to unlock the bootloader via ADB or some other alternative?
3, is there anything I've missed that I could try to get it to boot thus allowing me to perform number 2 from within Android?
Thanks all in advance. :good:
Maybe
No
Try flashing through ordin and see if it gives an error or completes, failing that - try flashing TWRP and see if you can boot into that maybe formatting data or wiping the system somewhere else might help?
Have you tried more than one charger / plug? - same thing? maybe bad wire / plug
I had this issue today and last week. there's a bug w the latest firmwares. havent had this issue on april/may builds.
Anyway my solution is.....
Once plugged in (lightning circle shows up and nothing happens)
press volume down + power till it reboots
once it reboots, boot into recovery by quickly holding vol up + power then release it 2 sec after u see galaxy logo
once in recovery. let it charge for about an hour so it should have enough juice to power on
The thing I notice is the phone does not like to have it's battery drained it this happens most of the time, but this started happening on the last few updates only.
So I will rolllback or install the one ui rom with custom kernel to stop it from happening ever again. it's annoying
hope it helps. it works for my end with the similar locked BL and stuff as u have

Thanks for the reply, I have tried a few different images via Odin but non of them work and I get stuck at the same place. I can't flash TWRP because the bootloader is locked, unless you know a way I can do it with a locked bootloader?

Thanks for your reply, unfortunately it still wont boot. It has charge as unplugged and currently sot on the android recovery screen. If you can think of anything else I could try I would be very grateful
You could try again with recovery mode, as it charges with that mode. I had to repeat the steps I took for a couple of times for it to boot. Or use another cable perhaps? that's what I did too. It's really frustrating.
