HELP!!! My Galaxy S5 G900V doesn't enter NORMAL Recovery Mode!!! & Stuck in BootLoop!

HELP!!! My Galaxy S5 G900V doesn't enter NORMAL Recovery Mode!!! & Stuck in BootLoop!
I think its kinda soft brick!
:crying: Like the heading says! I am stuck in continuous Reboot LOOP!!!
And something strange about this problem!
Let me brief it out!
Firstly tried to install the latest Lollipop firmware USING ODIN v3.09 which is OG5 AND I SUCCEEDED with a PASS!
And then when I tried to restart , it got stuck in "Recovery Booting...." blue text on top left corner of the screen followed by CONTINUOUS BOOT-LOOP OF SAMSUNG SPLASH SCREEN! Not EVEN REACHING VERIZON Boot Animation which is followed by every 2 VIBRATIONS & interval of 5-10 seconds of each loop!!!
And one more thing is I cannot enter the NORMAL RECOVERY OPTION MENU! Instead I ONLY
GET "Maintenance Mode Recovery Menu" Which has 3 options
1 Normal Boot
2 Factory Reset
3 Safe mode Boot
But Sadly and STRANGELY I CANNOT GET THEM TO WORK EITHER!!! As soon as I PRESS HOME BUTTON AFTER SELECTING THE OPTION FROM ABOVE IT DOESN'T EXECUTE IT INSTEAD GETS OUT OF THE "Maintenance Mode Recovery Menu" & Continues WITH BOOT LOOP sometimes followed with Recovery booting text ! Which I believe happens when I Press Power and any of the Volume Buttons!
So I ALSO TRIED FLASHING THE OE1 Lollipop Verizon Update via ODIN WHICH ALSO PASSES WITHOUT FAIL! BUT AGAIN SAME RESULT WITH BOOTLOOP!
AND ANOTHER STRANGE THING IS THAT WHENEVER I PLUG IN THE BATTERY THE GREEN LED NOTIFICATION LIGHTS UP SOLID PERSISTENTLY WITHOUT BLINKING! UNTIL THE BATTERY IS REMOVED OUT OF THE PHONE!
SO I reallly dont know what the problem or fix to this issue! But I request you people to help me out as soon as possible!
FYI
I can BOOT INTO DOWNLOAD MODE! I can BOOT INTO Maintenance Mode Recovery Menu!
I searched every forum regarding this issue but to no avail!
THANK YOU!

Semi boot-loop/chance of backing up files?

Hey guys, my aunt has an S5 which has issues now. Her phone can be powered on, get past the samsung logo screen until the initial lock screen to unlock the phone. But while trying to unlock, the phone freezes(anywhere from 1-5s after the screen appears) and reboots again. This repeats infinitely.
She's checked with a samsung shop and they say it's probably a motherboard issue.
I was wondering if:
1) If it's possible to fix the phone with another method - have tried booting into recovery and wiping the cache partition. Phone boots fine into recovery and bootloader. If not:
2) If it's possible to back up her files in the phone via recovery or bootloader before factory resetting the phone?
Try flashing the exact same firmware you are currently on in odin aka download mode with out any wipes to find out what firmware you are on boot to recovery mode and a line should tell you what firmware you are on currently
I can walk you through the process of flashing the firmware if you want
Download the firmware from Sam mobile.com just Google it
You shouldn't lose any data if all the appropriate options are checked in odin on a pc
I can't garuntee this will fix your issue but it is a way to prove if it is a software or hardware issue

Need Help! Samsung galaxy Note FE SM-N935s Bootloop fix

Guys i badly need your help! I recently bought a Galaxy Note FE with issues. The owner tried to root it he said and after trying to root it the phone bootlooped. He has no knowledge about this stuff so he decided to sell it. I Thought i can fix it by just flashing the stock firmware thru odin. I downloaded all the necessary files and after successfully flashing, it is still in the same bootloop. (Samsung Galaxy Note Fan Edition logo appears then Blue screen with android saying installing system update, then No Command) I can't enter recovery mode either. what should i do?
I noticed in download mode the FRP and OEM Lock is on. Please i really need your help
Edit:I found out that the phone is a Korean Variant and is branded by a carrier but i asked the owner and he said that it was unlocked
When you hold volume up + volume down and then power button phone will reset. Then fastly take your hands to volume down + home + power. When you see galaxy note fan edition take your hands from power button. Phone will go into download mode. Then you can use odin.

Galaxy S8+ in bootloop without recovery and frp locked

Hi guys!
I've read tons of threads and guides on Google but nothing helped me to bring to life my Samsung Galaxy S8 Plus. After hours and hours of test and probes I surrender!
Basically I was using normally my phone and suddenly has power off and showing the Samsung Galaxy Logo continuously. I've force reboot it with vol down+pwr button and after some minutes restart normally again. After 5min again the boot loop and stuck there. Tried again to power it off but didn't work so I thought was the battery (because is 3yrs old with heavy use and months ago I had the screen flickering and a battery drain to zero). I opened the phone, unplug the battery and the power button (because I thought was the power button stucked as on my father phone). So after mounted all the stuff in their place I tried to boot it and suddenly start to work again! I've backup all my things rapidly but again power off by himself and this is the last time I see it working.
So I tried to empty the cache entering in the recovery but it was useless so the only way seems flashing the original FW with Odin. Downloaded the right one with Frija, upload the rights files in Odin (Home_csc because I don't want to lose my internal memory stuff) and the phone automatically reboots, pass the Samsung logo and go in Upgrading mode with the blue android screen and a % increasing. After that by himself power off and nothing happen.
I read some stuff about my possibilities to recover it without losing data but a lot of tutorial talk about entering in recovery but I cannot do it! Simply does not go in recovery with vol_up+bixby+pwr_button even after force shutdown it with vol_down+pwr_button or reattach the battery. The only thing I'm allowed to do is put it in Download Mode to be recognized by Odin.
I've tried to launch ADB devices but it is not visible in Download Mode.
I've tried to flash another firmware for the same model (theoretically my one is unbranded italian) but I tried with WIND one because in download mode there is a text "Carried_ID:WIND" but this FW Odin fail to upload it.
I've tried to flash the TWRP with Odin but fails on the phone with error "Custom binary(recovery) blocked by FRP Lock". I've searched how to unlock it but without have access to recovery or phone settings seems impossible. And this phone has also OEM Lock.
I've tried again to flash the FW but the only difference than before was the blue android robot with stucked text "Installing system update", "Erasing" , "yellow advice notice" and finally a green screen with "An error has occurred while updating the device software.Use the Emergency recovery function in the Smart Switch PC Software". And yes, I already tried with Smart Switch but the program does not detect the phone.
I've also tried to flash the original recovery but nothing change.
Seems that my devices is bricked or a kind of boot loop.
In my situation there is something that I can do to recover the internal memory data? I don't tried to flash the FW with CSC file because I don't want to erase all the data.
My Galaxy was original since the purchasing, no root or flashed a FW, only OTA updates.
I've attached a photo with the stuff that appear in Download mode.

s8 successful flash but still on bootloop... and another question

okay so back in nov 12. i posted here about the issue of my phone.
i successfully flash the phone with the latest firmware (i think)
Galaxy S8 SM-G950FD - XTC - G950FXXUCDUD1​but still it didnt fix the loop (i only tried the home csc together with ap,bl,cp)
any option to suggest??
also another question about wiping the cache (i cant access the recovery mode cuz of the loop it will just proceed to no command then 2-3 seconds showing the recoverymode plus my phone screen is flickering already.)
is it possible to wipe the cache partition through pc (use of app or anything)?
i saw some post about just charge the phone for a long time (6hrs+) then the bootloop will be gone, is it true or some kind of myth?/ .. dang im running out of options.
i experienced the same thing with same actions, same binary and same firmware. still waiting for such solution from experts.
I have same issue. I flashed latest version of firmware for my S8+
It passed on Odin but never booted again. Stuck on Samsung Galaxy S8+ screen
Not going to recovery. I flashed TWRP but too did not work.
