Samsung Galaxy C5 stuck in bootloop on TWRP Teamwin screen

I flashed TWRP recovery for the device from Odin and tried to boot into recovery using adb reboot recovery. Ever since then the device boots till the TWRP teamwin screen and then restarts. It's stuck in a bootloop. It's got a non-removable battery so I cant remove the battery. I have tried holding down the power button for like a minute or two but it does not turn off. I have tried to get into download mode by holding down the combination but I cant and it is still stuck in a bootloop. What to do?
It's a rooted Galaxy C5, 6.0.1 Marshmallow.
If odin recognise your device , flash your phone back to stock firmare which you can download from sam mobile .
I know and I have the same problem

Man that TWRP recovery is for chinese version Galaxy C5 CHC
But you have a Hong Kong version TGY so you have a bootloop.Wait to your battery is complete empty and when you gonna plugg in a charge hold buttons to go in download mode and flash new official rom form sammobile.Is too bad the developers dont working on Galaxy C5.THERE IS NO TWRP FOR OUR VERSIONS YET!!?
Right now I have the same problem. The phone keep rebooting quickly....."rebooting recovery......." at flash screen. I tried pressing many buttons combination with no luck. The phone just bought yesterday !

One Plus one 64GB Stucked on boot logo, not booting into recovery, flashed stock rom.

Hi XDA Users,
I m feeling very helpless so i thought to write here cause every solution is here.
I am user of One Plus One (64GB variant). while normal usage i restarted my phone but it stuck on boot logo. i tried to boot into recovery mode by pressing Volume down + Power key but phone is not booting into recovery mode. i unlocked bootloader and tried by flashing TWRP but failed to boot into recovery. i flashed stock rom but situation is same. i also tried by flashing ColorOS then stock recovery.
Noting is working at least phone should boot with TWRP (twrp-2.7.0.0-bacon.img or twrp-3.2.1-0-bacon.img)
Phone is booting in preloader and fastboot mode only.
stock rom tried (cm-11.0-XNPH05Q-bacon-signed-fastboot and cm-13.1-ZNH2KAS1KN-bacon-signed-fastboot)
Everything is Failed.:crying::crying::crying:
Any help would be really appreciated.

Gionee S6 PRO, flashed the wrong recovery now stuck

hello !
I followed some tutorial in order to install a recovery for my gionee s6 pro, and what happened is that i got the recovery to install but my system won't boot. so i flashed (using fastboot) an other recovery which is supposed to be a good one, but wasn't.
now phone opens up, shows the android and condor ( algerian company who sold the gionee s6 pro as A8 Plus ) and says that my phone is not trusted because my bootloader is unlocked and i have to wait for 5 sec for my phone to boot;
after the 5 seconds my screen starts flickering with red and yello horizental stripes.
I can't access fastboot mode to reflash an other recovery and the stock rom, i alreayd gave up on recovering my files.
i can't access anything, and phone keeps rebooting after some seconds of flickering.
Help ! i am stuck with this.
I have the same problem. but there is very little information about the gionee area

[Problem] Blackview S6 has been unlocked and now it is bootlooping.

So today I was tring to root my Blackview S6 and I unlocked the bootloader but I think I installed incompatible CWM recovery and now I think it tries to automatically boot into recovery but I installed incompatible one. I tried holding power button, power and volume down button (every combination) and it still doesn't stop bootlooping. And my device has unremovable battery so I cant stop it from booting. And when its in the boot screen it says:
Orange state
Your device has been unlocked and can't be trusted
Your device will boot in 5 seconds
Thank you who will help me because I can't do anything now.:crying::crying:
EDIT: I know I need to clear data and cache but how do I do that?
This happens because when I unlocked bootloader I didn't reboot and instantly tried to flash custom recovery but I flashed an incompatible one so I don't have recovery and I don't know how to fix this.
I have the same problem
I have the same problem with my LeEco x620 , looking for help too, cannot do anything due to reboot every 5 second ..
