Need help with a bit different bootloop. - Samsung Galaxy S7 Edge Questions and Answers

Hi!
I have bootloop that I dont know how to solve. It boots up to where I am asked to enter my PIN to unlock SIM but there my phone freezes. Nothing reacts. After about 30 sec it reboots itself. Wipe cache seems to have errors as TWRP cant mount it for some reason. Any Help?

[Q] Defy keep on restarting not able to enter into CWM.

Hi XDA
yesterday onwards i'm facing this stranger problem.
Yesterday i updated defy with miuiandroid_Defy-2.4.6 but after that phone was restarting automatically.After times it stuck with the motorola logo.I was not even able to enter into CWM.After several attempts i enter to cwm and updated with the older version miuiandroid_Defy-2.3.9 after wiping the cache partions and dalvik cache.
But now it always freezes on boot up.If i kept it idle for some time after removing the battery it may open the CMW but it will freeze while doing the operations or some time it may reach upto boot animation of MIUI but it will again freeze. Two times it become normal but when i try to unlcok the phone by sliding it got restarted.
What should i do now.It almost like i'm not able to access CWM even after trying all the button combinations.With the M logo the computer is not detecting the mobile too.
Please help dear XDA...
Now i removed the battery and try to charge, i am able to boot menu at some times.But after formatting the cache its getting off.So not getting enough time to flash before that it either turns off or restarts

I'm afraid that you have to flash a (fixed) sbf using RSD lite. For instructions see 'how to flash' in this guide.

[Q] No battery error bootloop, help please!

New note 3 gets stuck on the "no-battery" bootloop and I have to plug it in the charger and reboot many times until I finally get it working. After a period of time, it does the bootloop again.
Any ideas how to fix this? Do I have dodgy firmware, I tried installing CWM recovery to start to fix this problem.
Thank you
EDIT:
Things I have tried:
- Restore phone twice
- Wipe cache

[Q] Unable to boot after encryption

Hi everyone,
I enabled the encryption on my unrooted unlocked G2. Once the encryption was done, it rebooted and asked for the pin to boot. In entered the pin but the phone keeps rebooting and asking for the pin again and again.
I have tried more than 20 times, sometimes it boots to android but it shows a warning sign in notification (backup account needed) and then reboots after a few seconds. I tried turning on/off but the same thing happens again.
Is there anyway I can get my data out of this mess before doing a factory reset? Maybe rooting it from download mode and mounting from recovery?
Thanks a lot!

[Q] Nexus 4 Boot Loop - Struck in Animation

Hi All
I searched all the threads related to boot loop but did not solve my problem. I was in stock lollipop and my phone was working without any issues. One fine day I felt that the phone is hot and tried rebooting. The phone was struck in the initial graphic screen. Tried restarting again but the same result. After multiple failed attempts, tried doing a factory reset from the recovery with no luck. Thought that something got corrupted, installed twrp and did a fresh install of the factory image. That also did not help. Then installed Chroma ROM and then back to Kitkat factory image and all the attempts failed. Then tried installing Chroma ROM again and after a long wait, it booted up. I inserted the sim card and the network was not detected and hence had to reboot again. The reboot resulted in the bootloop again. Then installed CM 12.1(without sim) and it booted after considerable amount of wait time. Then inserted the sim card and it was not detected and had to reboot again. Now struck again in the boot animation. Is this a hardware issue? Also does the SIM card insertion requires a restart in Nexus 4.
Tried clearing cache/ dalvik cache and did factory reset, file system check but nothing worked..
Can some one help me on this..

Have you tried out the Nexus Root Toolkit? I know most are against toolkits but it really can't hurt in your situation! Try following the guide while having the SIM installed. And yes, SIM card insertion requires a reboot.
Good luck!

Stuck on encryption lock screen, won't boot PLEASE HELP

Hey everyone,
So my phone died and then I got it charged and turned on and it booted up to the encryption lock screen where it says to start up your device, enter your pin. So I enter my pin and then its says, "verified" and then "starting android". and then a padlock appears on the screen, it opens, and there's like a load up circle going around it. At first, I let the phone sit to see if it would do anything but after an hour, I figured something is wrong. I dont know why this happened, I think I might have accidentally turned on the secondary encryption, but this really sucks, I don't want to have to factory reset and lose all my pictures and data. I can boot into recovery mode but sometimes when i turn it on it shows a screen that says installing update and has like a google ring looking thing that should be spinning around but it looks like its glitching out, after that screen it will go to a no command screen, and then it will eventually reach recovery mode. I really hope someone can help or knows what is going on because, I really dont want to lose all my stuff.
Thanks for your time
I tried posting link but im new, if you look up s7 edge frozen encryption, its the first link , another person describes the same issue.
I had this issue. In recovery, tell it to clear the delvic cache. Then try a reboot.
It too a few attempts before the phone would not boot directly into recovery. But once i got it to do a normal boot, it started normally.
Then after it's running, back it all up, boot into recovery, and do a system restore.
Hi I wonder if anyone can help me. I restarted my phone, it asks for my pin which I enter correctly. It then gets stuck on spinning padlock. I've tried a soft reset (I think that's what it's called, holding down power and volume keys). It restarts, I enter pin, it says starting android then gets stuck again. I'm not very tech minded (typical girl). Can anyone help. I'd rather not lose all my photos and apps. Thank you so so much in advance. Toni x
I am facing the same issue, but with a Samsung Galaxy S8.
- Safe mode: doesn't boot
- Recovery mode: works, clear cache doesn't solve the problem.
So since nothing worked to make it work (except the Factory Reset, but I didn't tried this option), I decided to wait in the padlock screen. After 3 hours the phone started.
I guess that the phone is decrypting some big file during startup. Indeed, some days before before this problem happens, I downloaded some big files via torrent (~2-4 GB video files).
I'll delete these files and make some tests to understand the source of this problem.
Have same issue after recent update, tried clearing cache and safe mode but didn't help, been on padlock for about 10 hours now, any solutions/experiences?
ps: on stock rom with stock recovery, no root or anything of that sort at all.
