Help With Complex Boot Loop - Verizon Galaxy Note 4 Q&A, Help & Troubleshooting

Hey everyone.
I recently just got someone's well used Note 4 because they got it stuck in a boot loop. I powered it on, it'll show the Note 4 boot screen where is shows the title of the device and the Samsung logo, shut off, and then repeat. I attempted to put it into recovery (vol+, home, and power, and when the Note 4 screen comes on, let go of power) but it continued the boot loop.
I can however put it into the custom ROM download mode, and then maintenance mode with vol-, power, and home. However, this arises MORE issues, as when I factory reset it, it made no impact, and when I attempted USB debug mode, it went back into a boot loop.
Any ideas? I've had plenty of experience with a OPO and such, but haven't touched a Galaxy phone in ages until now..
Appreciate it!

I had a similar issue with one of my droids. Consider flashing the stock recovery via Odin, make sure there's no SD card in it and as always clear cache and factory reset via recovery if possible. Good luck!

How to boot into recovery mode

i have a pretigio multipad 3270b. I was busy putting music onto my memory card when all off a sudden my screen went blank and when it came back on it was stuck on the prestigio screen the whole time. I tried all the button combination i can think of to enter the recovery mode.or clockwork mode to do a factory data resent but i don't seem to get into it, keep going to that one screen. I can get into the device at all. tried the reset button as well and still nothing. Please as anyone know how to get into that recovery mode or clockwork mode to do the factory data reset it will be truly appreciated. Thank you

Johan, I have a similar issue with my Huawei U8652 (2.3.6), I just removed the battery for a few seconds, put it back in turned it on and it worked as normal. But I too now can't do a factory reset now, phone works as normal until I turn it off and plug it in to charge or to the PC. Hopefully we'll get a solution to this, I'm thinking I may have to flash a default ROM but not sure how since my boatloader is borked.

[Q] Galaxy Tab 3 stuck in boot cycle after root

Hi Wonder if anyone can help?
I downloaded mirror beta from the app store to mirror my Galaxy Tab 3 SM-T210 to my apple TV3g.
Once downloaded i was informed that the device had to be rooted, so I used Kingoroot and followed the instructions. Everything was fine during the rooting process and completed informing me that it was successful.
The problem is after this the Tab is stuck in a constant cycle mode of the Samsang GALAXYTAB 3 boot logo.
I have managed to power it off ( Black screen) but have been unsuccessful in getting the device into recovery mode to try an hard reset.
I have tried all the button combinations I could find on Google but it only just shows the galaxy screen. Any help would be much appreciated since it is my daughters tablet and ill be in a valley of it if I cant get it restored.
Thanks in advance
Have you tried to Boot your Tab into Download mode?
If this working , flash Stockrom with Odin.
I'm in a similar situation with the logo boot loop except I am unable to shut it down. I hold the power button for 10 seconds and it reboots right back to the logo again with no shut down. How can I shut this down?

I got in the same situation trying to root my Tab. I wound up holding the power button down a really long time and then gently releasing; then I booted it into recovery and there is an "unbricking your 10.1 " post on XDA that has a stock 4.2.2 link.
Once you get the thing into recovery, and it took several attempts (like for two days)- I had given up and was thinking I had finally truly bricked an android) I got it into recovery and then used Odin to flash the original stock rom and it worked. Then Samsung almost immediately downloaded the OTA and I was at 4.4.2 stock.
The sd card slot is broken, so I am still trying to get the tab rooted, but for now just having it functioning in stock form is better than that Galaxy emblem slowly flashing every 5 seconds until the battery dies (Itried that too, thinking it may somehow recharge and reboot and something would be different-no such luck)
But I found holding the button down persistently made the difference, at least it seemed to.
Good luck

Tablet stuck in boot loop after factory data reset

Hey guys,
So few days ago I decided to do a factory data reset on my tablet since it was moving very slow. I activated it through settings (not recovery mode) and my tablet had about 35-40% of battery. Long story short, my tablet now is in boot loop, not showing anything else except "Samsung galaxy tab 3". The thing is that this is not the first time for her getting stuck there, before I had the same problem when tried to root it, but then I simply flashed a new stock ROM and everything worked fine. This time flashing a new ROM didn't help me, I also cannot access recovery mode, only download. What do I do now?
I have the same problem on my Tab 3. Hope someone has a solution to this problem.
I've been doing a lot of flashing lately, including the stock ROM via odin, and have found that the first boot doesn't complete... I shut it down, go into recovery, do a factory reset, then boot, and it comes up fine. I'm not sure why you can't access recovery mode, but if you can, maybe try that?
Removing the external SD card solved my problem, so if you have a SD card plugged in, remove it. You can plug it back when the boot animation will start (not the "Samsung Galaxy Tab 3" splash screen).

GT-N5100 soft bricked by itself

Hello everyone,
Yesterday when I was going to use my tablet I noticed it was off, but minutes before it was on, so I tried pressing the power button and nothing happened, plugged the charger in, nothing, no signs, it seemed bricked, so I tried to power through download mode and it worked, after that I pressed volume down to cancel it to start normally, the first samsung logo showed up (that one that says the model and stuff), but it was there for really long, i left it running and after 5 mins or so it changed to the pulsing blue samsung logo, left it there and about 30 mins later it was back to the 1st samsung logo again. I also tried a soft reset and booting to safe mode, didn't work either.
This tablet has no custom rom installed (I think it is on stock 4.4.2), the only thing different I installed is TWRP and root, years ago, but I cant boot to TWRP through the vol up+home+power, it doesnt work, tbh it never worked since back then, the only way I found to boot to twrp was thru "adb reboot recovery" using adb, which didnt work in download mode, I want to be able to backup some data before flashing it with Odin, so here are my questions:
1- Is there any other command I could try to force it to boot to recovery?
2- Is there any way to backup data via download mode on this device?
Thank you for your attention

Note 10+ stuck in boot loop

I purchased a note 10 + off ebay broken screen so I replaced the screen and a couple of ribbon cables and new charger port. But now I turned it on and its stuck in a boot loop. Only main screen comes on where it says note 10 plus 5g and then it goes to nothing and then back on again and it will continue i guess forever. But I can access the recovery boot am I screwed or is it an issue that can be fixed by a flash or firmware? Thanks
try going into recovery and flashing stock rom
Mine did that (2X) from an app conflict and I eventually got it booted into Safe mode.
See if you can pull up the boot menu and do a hard reset.
Are all the cables properly connected and connectors undamaged?

I did a hard reset from boot menu and it stayed in the loop. I cleared the cache and then reset and it stayed in the loop. When reset factory from boot it didn't even cycle through outside of boot menu it just went loop immediately. Could it be damaged board making it malfunction?

Way past my level of experience... there are people here that can help you though. Be patient.
At least it's powering up.
What version do you have? Find out. Once you do, get the firmware for your device and flash with Odin. If you are having problems getting into download mode, try to power down. Open odin on computer. Once powered down, hold volume up and down at same time as you plug device into computer. You should now be in download mode and able to flash firmware...flash BL..AP..CP...CSC
