Help with endless reboot and no access to revocery.

First let me apologize for putting this in Android Development. I am just stuck and thought you guys were the only ones knowledgeable enough to possibly help.
My phone woke me up this morning because it somehow got into an endless rebooting cycle and I cannot for the life of me fix it. I do not have access to recovery, when I try to enter recovery it just goes back into the boot cycle.
I did a wipe from HBoot but it did not help. I also reflashed some various pc36img files, but they did not help at all. I was not able to find a similar situation on the board, since the solution for the other ones all included going into recovery. Any help would be greatly appreciated.

Stuck boot

HELP! I just replaced the LCD, digitizer, frame, etc with a unit from Ebay, now the phone is stuck on the flashing "Samsung" screen. Is there any verbose boot that will display where in the boot process its getting stuck? I'd like to figure out if its a problem with one of the frame subcomponents or just an error with my assembly?
I already flashed back to DLK3 via Odin, so I know that wont fix anything.
Thanks in advance.

[Q] Stuck at Google Logo - Cant Enter Recovery - Cant Turn on debugging

Hello all,
I poked around and saw some similar issues, but nothing quite like what I am facing and was hoping you all could help me.
I woke up this morning to find my nexus 7 2013 32 gig wifi only on the "Google" logo loading screen. The tablet will not boot up into android.
I read up a little bit and found that I can factory reset using adb and fastboot...but here is my problem...USB Debugging is not enabled on my tablet, and I cannot access android to turn it on. Therefore, adb is not recognizing my device. If I try to enter recovery from the bootloader screen I get the same "Google" logo.
My bootloader is locked.
Really hoping someone who knows more than I about how these things work can help.
Thanks in advance for any assistance you can provide.

tab s 8.4 wifi stuck in TWRP boot loop

I was an idiot and did a factory reset (not while in recovery mode) and when everything restarted I ended up with my tablet stuck trying to load TWRP - I am/was running the lastest CM nightly from the end of May, I don't know what version of TWRP is currently on there. I just get the blue teamwin screen that stays there for about 5 seconds, flashes black, then back to the teamwin screen again. I got it into download mode one time, but as I was not in a situation where I could take advantage, and have since forgotten what I did to get it into download mode. (I think) I've tried all the button combinations with the tablet in the bootloop, and with it off (dead battery) to no avail. I've checked the forums and the few that I've found with the same situation as me, there is either no solution offered, or the solution was never posted, just that the situation was resolved - the thread most resembling my situation is this one http://forum.xda-developers.com/galaxy-tab-s/help/galaxy-tab-s-sm-800-stuck-flashing-twrp-t3219865.
Any help would be greatly appreciated. If you need more information, let me know. Thanks!

Need help!

I recently encountered a problem with my S6 Edge plus out of the blue. I had my phone charging when it suddenly restarted and began going into a charging boot loop, then after into a normal boot loop. My phone was not rooted,it had just began doing this :crying: . I tried many things such as flashing stock firmware in hopes of fixing it, but it continues to boot loop. I am at the end of the rope and have no where else to turn. Any help would be greatly appreciated
