Hi. I have followed the above video's instructions and the problem is still not resolved. It is still stuck on boot logo. No boot loop. Just won't go ahead of the start up logo. I cannot figure out the problem. I have downloaded the latest firmware using Frija and flashed it successfully using ODIN. It still does not work. After trying the standard solution multiple times, I did a NAND erase and re-partition using ODIN and flashed the firmware successfully, still facing the same issue. Please help, I am desperate.

Hi,
Followed the instructions. nothing happened.

Samsung Note 4 N910C Stuck in bootloop after Odin Firmware load and Nanderase all

Dear all,
Can you please me help me on this one.
My phone suddenly couldn't open. It was almost full storage.
So after a week I decided to reformat it using odin.
At first I tried loading the odin and ap stock firmware of N910C.
However it is stuck in bootloop.
Then I tried stock firmware and then installing twrp. but still stuck in bootloop, and couldn't go to recovery mode. Only download mode works.
Finally I decided to use Nand-erase all, thinking I could erase cache (but stupid). but still I'm stuck in bootloop.
I tried flashing a pit file (but not sure if it is the right one) but still stuck in bootloop. Couldn't go to recovery mode.
All I can do is download mode and pass firmware..
Guys, any idea/ help what should I do? Thank you very much.

How to Fix the bootloop Samsum Galaxy S7 Verizon?

I try to root my phone using this post https://forum.xda-developers.com/ve...-to-notes-root-install-xposed-unroot-t3411039, but I think it is too old to apply on my phone. I followed step by step until I installed the root.tar file using Odin. After that moment, my phone went on with the boot loop, but I can still access to recovery booting. I went on and try to find a way to fix it. I saw youtube saw a video that designed especially for S7/S7 edge. He downloaded a firmware from SamMobile and use Odin to reset the whole thing. I tried the same, using the Odin, getting into the Downloading mode. Successfully download the firmware into my phone, and phone starting to reboot. Again that same boot loop except, I couldn't get into Recovery booting though.
Now the the phone keeps rebooting with the Recovery Booting on top of corner left.
How can I fix it?
Should I bring it to store?
I read a guide here confirm it's not bricked.

After understanding what are definition of AP, BL, CP, and CSC. Instead of flashing only AP, I flash all 4. And for some reason, I got into the Recovery Mode where I can factory reset my phone.
Power+VolumeDown+Home will reset phone. Then hold Power+VolumeDown+Home for Download Mode or Power+VolumeUp+Home for recovery mode. Once in recovery mode, just wait a minute or two and that should always bring you back to the standard Android recovery screen where you can either apply adb update.zip via sideload or reboot phone to system (which should kick you out of this loop).

Stuck in a boot loop and can't access recovery mode

So I flashed a custom rom and it required a specific TWRP recovery. But after installing the custom rom I had to install another TWRP recovery otherwise it wouldn't boot into OS (this recovery was probably unsupported and thus my phone was forced to boot into OS)
So every time I wanted to boot into recovery mode I had to use an app like flashify and flash the first recovery to boot into recovery mode. And after finishing I had to flash the "unsupported" recovery again in order to boot into OS.
Now with the "unsupported" recovery, I installed Xposed and some modules and then restarted the device. And..........boom! The phone is stuck in a boot loop! And I can't even boot into recovery mode.
Now here's the other nightmares I'm getting:
1. Cant use ADB to flash a new recovery because my device is "unauthorized" and in order to fix that I need to go to developers option which is not possible (because of boot loop)
2. Uninstall Xposed: button combinations aren't working and I cant go to recovery mode to flash the uninstaller zip
3. vol up + vol down + power button doesn't open recovery because the recovery is "unsupported"
4. Can't even boot to fastboot mode by holding vol down + power. It tries to boot into OS and starts boot looping
5. Can't use sp flash tool to flash stock rom or recovery because whenever I connect the phone to PC, the phone tries to boot into OS and....you guessed it starts boot looping.
Now I'm out of ideas and really depressed. If anyone can help me out with this I'll be grateful forever.
My device is: Lenovo k4 note
Chipset: MediaTek MT6753
Currently on this recovery: https://androidfilehost.com/?fid=673368273298981920
Got this recovery from here (recovery2): https://forum.xda-developers.com/k4-note/development/unofficial-resurrection-remix-5-8-2-t3570195
Thanks!
Update: The problem is solved after flashing stock rom via sp flash tool
Can you please help me im havifng the same problem

I think the pc cant dtect my device same problem bro after installing new rom it keeps on rebooting after the lenovo logo. Cant also access the recovery mode. Please help me
Bro I'm not an expert. Someone from XDA discord server helped me with this. And I actually forgot the exact thing I did to be honest. I downloaded the sp flash tool on pc and downloaded the stock rom. Then flashed it to the phone. You have to connect your device via USB before. For a detailed guide you can search on YouTube with something like "how to flash stock rom via sp flash tool"
Or ask in the discord server. They will surely help you.
How did you flash that? Can you please explain step by step
Check this link: https://firmwarefile.com/lenovo-k4-note-a7010a48
You can download the stock rom from here. And there is also a tutorial on how to flash it. I followed it. Hope that helps!

Thanks, the problem is my phone is struck on the Lenovo logo, it's not turning off but my computer deducted it as Lenovo device
If ADB can detect your device then you can just flash a new recovery and you should be fine. But as I said I'm not an expert so I'd suggest you to ask for help on the XDA discord server. That's where I got help from.
Did anyone found the solution?
Thanks
Can any one find the solution of that problem , because my lenovo k4 note also stuck on boot looping logo... and vibrate like bootup time

Still bootloop after flashing with odin

Hi everyone, I wonder if you guys can help me.
Yesterday I flashed magisk and after rebooting out of sudden when the screen enter samsung animation logo it bootloops again into samsung logo with the one with powered with android.
I tried to enter recovery mode but to no avail.
I still could enter the download mode though, so the next step I took was to flash the stock firmware via odin.
The flashing was a success, but my device is still stuck on the samsung logo with the one with "powered by android".
can you guys help me to solve this problem?
You could try Frija for to download your firmware.

Did you flash multiple part ROM?
That's what might help better than all-in-one ROM file.
Dunno if Frija offers that kind of download as well like samfirm did.
If it doesn't try samfirm and check "binary nature" box.

SM-T555 Bootloop

Hi
I have tried to flash TWRP to my sm t555 but now i got only bootloop on samsung logo.
After that I had flashed stock recovery - but still nothing.
OS - 7.1.1 - Nougat
I can go to download mode
after going to recovery mode - hang on samsung logo and shut down,
after normal boot - bootloop.
What can I do?
I have the same issue after trying to root.
Did you find a solution?
edit:
I managed to succesfully flash TWRP from this thread, however it didn't resolve the bootloop problem.
edit:
I wiped everything and flashed official ROM, this solved the problem. Then I rooted using different method
