[Q] Phone stuck in reboot loop! (Not recognized as device on computer)

Help! My phone suddenly froze and crashed; rebooting the device, caused many strange errors and glitches to occur (examples: the Wi-Fi would be stuck on "turning on", there would be no service on the phone, preforming various tasks caused it to reboot such as attempting to uninstall apps, the phone would state that I had no SD card, the home button wouldn't respond). Attempting to fix this, I did a factory reset. Doing so lead to a constant loop of rebooting in such that when it reached the screen for the language selection it would then reboot after a few seconds. I can only reboot to CM recovery. Furthermore, when connecting the phone to a computer it is not recognized as a portable device (not sure if this affects whether or not I am able to enter fastboot). I did not root the phone prior to this incident. I was running CM 11S 38R prior to this incident. I am at a loss at what to do.
Please help.
I am quite inept and new to using any in depth fix so please be patient with me.

Flash a new Firmware over fastboot. Here is a good guide: http://forum.xda-developers.com/oneplus-one/general/guides-bacon-timmaaas-how-to-guides-t2839471

Z5 stuck in bootloop (100% stock firmware)

Over the weekend, my Z5's battery died. When I booted it back up, it started running dexopt which I found unusual. Once it completed and switched to "starting apps" the phone rebooted and began running dexopt again. The next time, I ran logcat and saw that com.sonymobile.wifi/.internal.SomcWifiService was ANRing at the end of starting apps which caused the phone to reboot. Any ideas how I can fix this?
This is one of the first phones I've used that is 100% stock firmware and not rooted or unlocked. Any ideas what may have caused this or how I can get out of the boot loop?
I tried running adb shell svc wifi disable as a last resort but it didn't fix it.
EDIT: I've created a gist with the logcat during dexopt and leading up to the crash here: gist.github.com/gpeal/d580d12c8f8f01569128

Try to repair your phone with pc companion,or remove sd card if you have one and try without it.

Update: I was somehow able to get it to boot in to safe mode while trying to do the 3 finger salute to get it into recovery mode. After it booted into safe mode, I had it forget all wifi networks (hoping that it may have caused the wifi anr). I rebooted after that and it booted back up normally. I still have no idea what caused the ANR though.

How did you get the phone to boot into safe mode?
Mine is stuck showing "Optimising application 1 of 76" and I have to let the battery run out before I can charge it and try again. Sometimes it gets through all 76 and then says "Starting Android" and then just re-boots and it all starts again.
Plugging it into the PC doesn't seem to give any response either as the thing won't turn on so I can't run the PC repair option in PCC, any advice muchly appreciated

Turn the phone on and directly press volume down and keep it pressed till the phone boot will take you to safe mode.

If you have adb setup, run logcat while the phone is optimizing. Let it continue running until the phone reboots. When it does, the adb connection will close and you'll be able to find the crash/ANR pretty close to the end of the log.

Thanks guys. I actually didn't need to do either of those things, I found a little reset switch next to the Sim card tray, pressed that and then it took twice as long as previous attempts to optimize the apps but then it booted up fine

Unlocked bootloader reboots 20 seconds after loading android

I have a SM-986U1 with an unlocked bootloader. I had it rooted and running, but because of some issues with auto brightness not working, I factory reset it. Ever since, whenever the phone loads into Android, it restarts after maybe 20 seconds. When I'm in Android recovery or even twrp it doesn't do this, only android system. I have tried to nand erase it but after Odin says successful it reboots, it doesn't clear partitions at all. I have flashed multiple firmware and gsi but nothing has worked. I suspect it has to do with a corruption in the ftp lock. When I can get in fast enough there is no account to remove, but it always shows ftp lock in download mode. I have had this issue for months, and the phone can't be used. Any help is appreciated. Thanks in advance.

Here is similar issue: https://forum.xda-developers.com/t/sm-n9860-soft-brick-recovery.4193859/ and looks like no fix yet. But you can try to bring in the Samsung Repair Centre.

How to bypass Recovery Mode?

Hello everyone,
So I have a rare issue. I have a OnePlus 6. Today, it started to act really weird. It became so slow that even swiping on home screen with no apps opened takes like a minute to register. I forced power off the device. When powering on again, it seemed like it take around 10 minutes or so to boot. Again, extremely slow. I tried everything from restarting and clearing app cache while in the system itself but no luck.
So, next thing I booted to recovery mode, typed my pin, and cleared system cache and settings. It started to progress until just a tiny bit left before the end of the progress bar, and it got stuck again. Kept like this for a long time. I had to force power off the device again. Now, when I try to power on the device, it launches into Recovery Mode. I tried my pin but it wouldn't decrypt and looks like the device is no longer recognizing it. I tried a couple of "default passwords" but it wouldn't work either. It only gives the option to "Forget Password?" Which should wipe everything off the phone. The only other mode it launches into is Fastboot Mode. I'm using Stock everything and Device State is Locked. I'm not sure where to go from here.
Now my question is, is there any way I can open my device again without losing data? Maybe some way I can pull files using adb in that state then factory reset? Or maybe someway I can bypass Recovery Mode and boot again? I have important data that I can no longer access if the only way to fix this is by wiping everything!
Can anyone help? Much appreciated in advance.

When a phone permanently boots into Recovery mode then either Android OS is corrupted - for whatever reason - or phone's bootloader is misconfigured.
If phone is accessible by either ADB or Fastboot you can try to exit Recovery mode by forcing phone to boot into Android OS ( Normal mode AKA System ) by applying the related ADB and/or Fastboot command.

mine solves by itself, I turn it on and suddenly it worked

Wipe data on TWRP recovery if you are S-OFF or flash a RUU with a computer if you have a stock rom. All your data will be destroyed.
