Stock Untouched Galaxy S7 Edge DUOS Bootloop issue - Samsung Galaxy S7 Edge Questions and Answers

Hello Everyone,
I'm having an issue with my S7 Edge since yesterday. I was on playing some music when my phone suddently shuts itself off. Then it boot up only to be in the bootloop issue as mentioned. I tried going to Recovery Mode but volume up and power key didnt register however I am able to enter Download mode.
Now in download mode I see the following:
ODIN MODE
DOWNLOAD SPEED: FAST
PRODUCT NAME: SM-G935F
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Custom
FRP LOCK: ON
Secure Download: Enabled
WARRANTY VOID: 0 (0x0000)
RP SWREV: B:2 K:0 S:0
About my phone, it is actually the black galaxy s7 edge duos (SM-G935FD) and running on Nougat. I'm not sure what version it was running on but when I first bought it 2 years ago, it was running on Marshmallow out of the box. I have never rooted the device nor flashed or installed any custom ROM. It was untouched but one time few months back it experienced boot-loop but was fixed when I entered recovery mode and wiped the cache. Only this time it isn't working.
Last night I tried to download 2 types of stock firmware from Sammobile for the SM-G935FD. Flashing it on Odin for both firmware worked but bootloop still exist. I still cant enter Recovery mode except Odin mode.
I don't even know where to begin.
Please help.

Just download latest firmware for your region through samfirm or updato/sammobile. Then use latest odin version from here https://forum.xda-developers.com/attachment.php?attachmentid=4431597&d=1519662712
Flash using normal csc, not home csc and you will be good. Don't tick auto reboot in odin options. Don't tick anything except F.Reset. After odin says flash is successful with a pass, disconnect usb and force restart from download mode by holding power+vol down+home when screen goes black immediately change from vol down to vol up key while still holding power+home keys. It will get you in recovery. If you are still unable to get in recovery then I guess you have faulty buttons or some other hardware problem.

I won't recommend, do it on your own risk. Extract the normal csc file and there will be a pit file there.
Are there any error messages displayed in odin/phone?

Yes, leave it to bootloop for a while. For me I'm not sure what really happened. I was fed up with the phone bootlooping even after trying to flash it with a stock firmware (latest version) from sammobile. What I did, I just threw the phone into the bag while bootlooping because I was in a hurry to go to work (Already given up hope). By the time, I reached office (approx. 30 minutes drive) I took out the phone only to find it on the initial setup screen like when you first bought it from the store and turning it on.
Just an update: My S7 Edge is still working with no issues of bootloop. Using it for playing games and other stuff. It's no longer my daily driver phone as I have switched to SG S9.

2. Odin to official samsung lolipop - still reboot loop with the words "Recovery booting..." blue text top left corner. Will buzz 2 times and just reboot all the time.
Still no recovery mode.
3. Tried CF-Auto, Philz and twrp recovery all of them reboot loop with the words
RECOVERY BOOTING...
RECOVERY IS NOT SEANDROID ENFORCING

Samsung Galaxy S5 Stuck at Samsung Logo

Hi guys first i want you to know that my english is bad...
My phone is G900K - SpaceX Rom 5.0
I am using SpaceX Rom 5.0 for weeks and it is buggy, i experience random boot,app crash,fast battery drain and freezes.
Yesterday i reboot my phone and after "Android is Starting" i got message that System Crash or System UI i am not sure what it is but it has System word in error report. Then my phone didn't start so i remove the battery and put it again. After pressing on the Power on Button my S5 starts and i notice the Blue Light in Upper Left didn't Light Up and my phone didn't boot to 2nd Samsung Logo. When i press Power On Button my S5 will turn on and 1st Samsung Logo will appear then It will Turn Off then Vibrates then goes back to 1st Samsung Logo it keeps repeating. Also i try Recovery Mode but i can't enter to it my phone will repeat the same process as i Turn On my phone. I can go to Download Mode, And i flash Stock Rom and after flashing Stock Rom there's a blue text in upper left Recovery Booting... but its not booting into recovery, It will just turn off again then vibrates then goes to 1st Samsung Logo.
If anyone experiencing the situation right now you can comment​
Same issue here. My phone is stuck at RECOVERY BOOTING. Is there anyone who can fix this issue? Thanks.
Boot to download mode (Vol down & Home & Power)
Flash stock ROM from sammobile .com with ODIN
Instructions under the download on their site
Go into download mode and do a firmware upgrade and initialisation through kies3. You will need your serial number and model number( on the white sticker behind the battery. in kies3 go tools> firmware upgrade and initialisation, then follow the on screen steps. I used this when I soft bricked my note 2 when I had it, I personally find it's the best way to restore a samsung device.
You should try first with kies3, it did help me to recover from custom ROM installation.
If it fails, flash stock with Odin3 from phone download mode is your last option.
I'm having the exact same issue! Been trying to flash the stockfirmware, but still stuck in recovery booting loop! Even trying to get into recovery mode has it looping. Kiess 3 says that my serial number is invalid, so matter which number I put in too. Hoping for some help!

Mine is the SM-G900W8 with Telus, so if we have the same model, I could probably give you my serial number cause I never had issues with mine. I know I have read places that sometime when people get stuck in recovery like that, they do a factory wipe and cache wipe in the stock recovery to get it to boot.
This same thing is happening with my s5 Verizon.. Need help to fix this i've tried flashing via odin, factory reseting..nothing worked
Can anybody help me please....thanks

Stuck at installing update s7 edge sprint

I have this galaxy s7 edge from sprint, from day 1 i was using it ok but there was an update available so i went for it OTA. the phone completed the process correctly, everything was fine. Then i powered off the phone (i had not done that since i got, kept it on and plugged during the night) that's when it started to bootloop into the logo.
I tried to flash the stock firmware, as the phone is able to go into download mode. Unfortunately as soon as the phone restarts, it wants to install an update, then the process stops at 25% or 32%, it changes every time.
Any luck ? I got same problem with my s7 edge
Do you all have disabled apps? Did you root? If you install an update with certain apps disable that's known to cause a bootloop but that's just my guess. If you say you don't have disabled apps I don't know then.

Before flashing the stock firmware, try this: Boot into stock recovery & perform a factory reset. Then boot into Download Mode & flash a firmware again.

Same issue. Factory reset from revovery. Downloaded lastest firmware for the model from SamFirm. Flashed with ODIN.

hello i had this problem while i was trying to root and unlock the phone
this is what i did hopefully it works for you too
1* download the latest firmware according to your android version
use odin3 v3.13 patched version
2* boot into boot loader
chose Bl on odin and the pit file , uncheck re-partition
and press start , that will get your phone unbrick then flash the ap file and then cp and csc that shoud do the job :good:

SM-G930V Verizon stucked into Recovery Booting... (BOOTLOOP), hard bricked? HELP!

Hello guys this is my first post.
I have a SM-G930V Verizon S7 that previously was in bootloop with OREO, but constantly rebooted at the beginning of the setup I mean when it says hello and so on.
I flashed Nougat without problems and booted normaly but then the FRP was doing his work, I could not boot since I didnt know the email or password.
I then flashed a file that I found to bypass FRP and succeded. I finally got it working very well.
After a while when I tried to clean bloatware suddenly frozen and then never booted again, I wanted to root but couldn´t.
NOW when I flash any ROM from Marshmellow , Nougat and Oreo, it says PASS in ODIN but I cannot enter the recovery.
Vol+, Home and Power gives me a blue line top left saying RECOVERY BOOTING..... then a blue screen saying ERASING... and the reboots again and again. The menu that I can get is the Maintenance Boot Mode (Vol- Power). This menu has 4 items:
1.Normanl Boot, 2.Factory Reset, 3.Safe Mode, 4.Power Down, and the only who works is power down.
I don´t know how much batery is left because I don´t know if in this menu or in download mode the battery charges.
I flashed the last OREO from SAMMOBILE, I also flashed the ROM wich I grabbed when using VZW Software Upgrade Assistant which supposed to be repairing the device but nothing whatsoever.
I don´t have any new ideas my head is full and hot now. PLEASE HELP will be appreciated.

Galaxy S5 SM-G900M boot loop (?)

Hey there I have a Galaxy S5 that was running LineageOS, I started having some trouble recharging it, couldn't figure out if it was the battery or recharger.
I decided to leave it at a repair shop and afterwards buy a new battery from them. The first day it was working normally and I left it the whole day just recharging but then it started having some problems rebooting automatically. Now it keeps "rebooting" all the time which wasn't a problem with the old battery, the Galaxy S5 logo appears then it reboots and appears again etc.
I can't boot into recovery either but strangely enough I can get into download mode without it rebooting and it seems to work fine, even unplugged from any power source, this confuses me because I thought it was the battery.
Without being connected to a USB cable:
Power: Vibrates, Galaxy S5 logo appears, "recovery booting..." appears on top left, reboots immediately afterwards (doesn't enter recovery).
Volume UP + Home + Power: Vibrates, nothing appears on screen, slight flash on the screen as if it was damaged (but it isn't).
Volume DOWN + Home + Power: Boots into download mode absolutely fine, screen working 100%, doesn't reboot (can flash normally).
Being connected to a USB cable:
As soon as I connect it, the phone automatically tries to turn on as if I pressed the Power button ("recovery booting..." appears on top left), keeps rebooting as mentioned before, if I remove the battery while keeping it plugged in, it keeps doing the same thing but the Galaxy S5 Logo lasts longer on the screen and no "recovery booting..." appears on top left.
Volume UP + Home + Power: Same as just pressing Power mentioned before, keeps rebooting as mentioned but no slight flashes and screen works unlike when unplugged.
Volume DOWN + Home + Power: Boots into download mode absolutely fine, screen working 100%, doesn't reboot (can flash normally).
What I've tried so far:
Flash original ROM with Odin, flashed fine but still rebooting.
Flash TWRP on top of original ROM with Odin, flashed fine but still rebooting.
Flash "G900MUBU1BOE1_IUS1BOE1_v5.0_Repair_Firmware" along with the included .pit file, flashed fine but still rebooting.
Flash https://www.sammobile.com/samsung/galaxy-s5/firmware/SM-G900M/ZVV/download/G900MUBU1CPF2/88002/, flashed fine but still rebooting.
Flash "G900MUBU1BOK3", flashed fine but still rebooting.
Flash "G900MUBU1ANG3", flashed fine but still rebooting.

No luck
Same problem here, with a G900I. No luck, I've tried two "4 file" repair firmwares with repartitioning and one stock single file, no luck either.
