S8 stuck on boot loop, recovery mode. (can only access download mode) - Samsung Galaxy S8 Questions and Answers

so yesterday i decided to restart my s8 cuz it feels like there are times the phone screen malfunction like while i was playing the control pad got stuck for 2-3 seconds (tested with 4 games also same result) and i proceed to eat my brunch while i wait for the phone to restart completely.. after that i noticed the phone is stuck to boot (Galaxy S8 powered by android) after 1-2 minutes the phone will proceed to recovery mode (no command ) then its menu and after 7seconds the phone will restart to boot again (infinite loop)..
i tried to flash it but i really dont know what build or firmware should i download..
idk if i already soft brick it but after flashing it the odin always shows a fail result.. (but it is still in boot loop and can still proceed to dwnload mode)
i saw this message in phone while in download mode
SW REV. CHECK FAIL (BOOTLOADER)​also saying device 12 binary 11 (i researched about it and found that my phone is up to date abd the firmware im trying to use to flash is old, the thing is i dont know what firmware should i download))
My question is can this be saved by flashing it with latest firmware? and if its possible can you send me a link of the phone firmware that match to my device.. i already searched in sammobile and the current firmware for my phone there was the february 2021 (02-21) firmware..
since i cant check my build number or anything (cuz of the boot loop).. ill justput here the details about my phone..
*model : galaxy s8 (SM-950FD) ,dual sim,64gb rom 4gb ram, exynos variant
- i still have the box of it.. (bought the phone december 2017)
*all i know is that my phone is up to date (last month i checked it settings and the phone says it is up to date)
*last year (June 2020) - the phone screen starts to flicker but i can still use it by turning on the AOD and set the brightness to 50% then the screen will go back to normal
*July 2020 i tried to reset my phone hoping that the screen will be fixed, it went smoothly in a week (no flickers even @low brightness) and then after that the issue goes back again so i just keep it that way and back to Turning on the AOD to fix it.
*last week of Oct 2021- so for after a year & 4mos. and already used with the flicker issue. the fingerprint sensor starts to malfunction (so sad i cant access the samsung pass anymore)
my last restart of the phone was this time.. and time to give up with that fingerprint issue
* i flash it earlier today this is the firmware i downloaded//
SM-G950FDPhilippines (Open Line)2021-02-02G950FXXSBDUA3Android Version 9
i tried that firmware cuz im living in the philippines plus it is dual sim (i presume its an openline) however odin tells that this firmware is old..
that is all i know about my phone.. let me know if you need more details about it.

device 12 binary 11 - does mean you are flashing older firmware than what is on your phone.
device 12 means your on binary/bootloader 12 and binary 11 is firmware trying to flash ie: G950FXXSBDUA3
this may be the latest version G950FXXUCDUD1
you can use this pc app to download latest firmware. See last page for download link

In using Odin
Home_CSC file will keep your apps and data ie: all apps and data that you have installed.
CSC file will wipe all data and apps ie: same as factory reset.

HELP !! My Note 4 (SM-N910F) Bricked After Official Marshmallow Update !!

Hi
I have this Samsung Galaxy Note 4 (SM N910F). I am here in Pakistan. I purchased my Note 4 from UK and Its on EE. I was using it here and it got an Official OTA Update of Marshmallow which I installed. After a couple of days, my phone automatically got bricked. I contacted a local mobile repairing shop who dumped some other unbranded international firmware which changed its CSC too [CSC after updating unbranded firmware = (N910FOXX1COH1)]. The firmware was not working properly and had glitches.
Now i want to flash its stock EE Firmware which i have downloaded. I tried to flash it with ODIN but then i noticed that the CSC was changed so i tried to change the CSC by rooting the phone and for that i reboot the phone in Download Mode. The phone usually goes to black screen and does not start after proper power off and I need to soft reset it (By pulling the battery and draining battery charges) in order to turn it on everytime. After a couple of restarts in this way, the phone finally stopped to turn on. In download mode i had an error of "PIT File not found" while i tried to root it through ODIN. I tried to normal boot the phone but now it doesnt boot at all.
I need to boot it so that i may change my CSC to flash my stock firmware (please tell me if changing CSC would be necessary, Current CSC = N910FOXX1COH1,
Required CSC = N910FEVR1DPE1)
Any help would be appreciated. Thanks
Try to flash your EE rom with pit file for note 4 910f.

Thanks for the reply !
Is it necessary to change the csc to UK region before flashing the UK firmware ? My phone is not booting to download mode either right now. Earlier today it was booting infact i tried to exit from download mode 2 times by pulling the battery but every time it automatically reboot to download mode. That was the moment when i shut down the phone by pressing home + power and after that it doesnt turn on
UK firmware includes UK csc. Then you don't need to change it manually.
But if your phone won't turn on I don't know how to recover it. (try to Recharge your phone and then go to download mode. I think your battery is fully discharged. )
If you can able to access download mode, flash firmware with the pit file using Odin.

Stuck on Samsung Logo Odin and Wipe done

Hi, I recently became a Galaxy S6 Edge+ as a gift, which is stuck on the Samsung Logo (blinking). I am not new to flashing Firmware and Roms (came from the HTC HD2 and Dell Streak 5), but everything I do, I can not come through this. Now I need your help, since it's my first Samsung device. Maybe I have something forgotten?
My device:
SM-G928F with Regional Code AUT (free Switzerland firmware) --> Also Samsung Smart Switch shows me this AUT Version (but it wont recognize it, shows it after typing in the serial)
What have I done:
Samsung Smart Switch does not recognize it.
The last 24 hours I have downloaded the firmware through SamFirm 4 times, I have flashed the phone via Odin about 8 times, after the flashs I have wiped the cache and resettet data (full wipe) through the recovery. One time, the phone came to the android optimatization, but it was stuck on the last app (was 30 minutes on this), after reboot it was stuck on the Samsung logo.
Now I need your help. What can I do further? Do I missed something? Any ideas?
Something strange I noticed: When the phone is off and I plug it in to the wall, the battery drains. I have to put the phone to Download-Mode to charge it. Is it linked to the firmware problem? The charger is original Samsung.
So, I flashed TWRP, the Note7 Deodexed Rom and SkyHigh kernel, but it's the same... any sugestions?
I read about a pit file, what is that? May be this the solution?
What I did the last 3 houers was to test Smart Switch With the mac version, the rescue function did not work, the hole program crashed each time. On the windows version it suceed, but my phone is showing just the blinking Samsung logo. Every now and then it vibrates, but nothing happens, so I am at the start of the problem again. Any ideas?
Next update: I flashed the original firmware with a pit file 3 minutes ago. I learned a lot, learnt that the pit files are the partition-files. Now I'm hoping, that with the new partitions it will boot properly :good: . Stay tuned!
Still the same issue. Please help me
Whenever I start the Recovery, it says "installing system update" and then there is a dead Android, does this matter?
A 4 part firmware with pit file did not help. I downloaded another Firmware from another source, also the same. Now I will do a downgrade and look, if this helps. Pleeeeease, help me!
Infos from the download mode:
Produkt Name: SM-G928F
CA_Type: CA_3
Current Binary: Samsung Official
System status: Custom
Secure Download: Enabled
Know warrenty void: 1 (0x0203)
RP SWREV: B:3 K:0 S:1
Maybe the TWRP Log helps: There are errors in writing, is there something missing? It is the original firmware, with the newest TWRP and SuperSU installed. Still stuck on Samsung (animated) logo.
Listen do you have windows on ur mac i use parallels
but do you have windows anyhoe

Same here
Hello,
I'm quite new here, but not with flashing.
My son got an S6 Edge plus too, with almost the same problem.
I tried also almost anything, the last few days.
ADB sideload, Odin several versions.
It started out with FRP lock.
After I tried al I could find I think it bricked.
And now it is in the state as described above.
Only first screen and draining the battery if not in download mode.
And when I put it on USB cable it says: "An error has occured while updating the device software. Use the Emergency recovery function in the Smart Switch PC software."
But Smart Switch doesn't recognise the phone!
I can however get the phone in download mode by pushing vol. down, power and home and then vol up.
But in Odin only works: Pit, CP and CSC.
With AP and BL I get errors and fails.
Please help?
For me AP and BL works with Odin. I am a step furhter now. First I flashed with the option: Erase All Nand. Then I installed TWRP and a made a repair for the System and the Caches partitions. With SuperSU installed, and the caches wiped (manual, dalvik and normal caches), it says "Android is starting, Optimizing Apps" and then "Androis is starting, Starting Apps" on a blue screen and when it loads to the end, it is stuck there.
.You get only the first Samsung S6 Edge+ Screen? Then the system files are missing, there is no OS to start (flashed with AP in Odin). Your flash problem sound quite strange. Did you test another cable?
If you want to do it with Smart Switch, the phone should be in download mode. I also had to try it several times. Did you installed the drivers?
@ KatariaMax: I have Windows and Mac PCs, no Parallels. Does it work with Parallels?
So, one problem less. With the Audax rom and kernel, the phone charges normally (but not with Quickcharge), so I don't have to put the phone to download mode. But here is the same problem, after "starting apps" it is stuck. I will do a log from the install, maybe this helps.
@ HugoGroot: Maybe the second post could be the solution for you: http://forum.xda-developers.com/galaxy-s6/help/s6-bricked-t3497687
I read about Sony devices, which are in a bootloop because of the battery. Could this be possible also for Samsung devices? I have bought a battery, just to be sure. Any other suggestions?

S7 Stuck in Bootload / Updating

Hi all,
since one day i´m totally wrecked up with my SM-G935F. On Monday morning the display was frozen. I looked in some forums and used odin to flugh the newest version (7) to the phone. After clearing the cache it worked quite well for about 3 hours then freezed again. Since that i´ve tried so many options, all leading to nothing ;( I´m quite sure that there must be a solution and hope for your help.
The actual status is:
The phone shows the Galaxy S7 Edge screen, then the "Installing system update". This crashed every time (no command) and then a black screen is shown with some information in the upper half:
No Support SINGLE-SKE
Supported API:3
# Manual Mode #
-- Appling Multi CSC --
Applied the CSC-code: DBT
Successfully applied multi-CSC
Successfully verify for dmverity hast tree
Sometimes after waiting it jumps to the "bootloader". The normal way with the volume up + power+ home is not working at the moment or i´m doing something wrong.
I´ve tried a few fixes:
-> downloaded the newest Firmware, an older version and the oldest one from sammobile and install via odin
Normal install in AP via Odin stuck an recovery.img​I renamed the file without md5, open it and extracted the files. From there i tried to single upload them (boot, system and recovery) It freezes at system...​
-> flash home file first with odin
it stucks on RQT Close and don´t finish​
-> install new firmware via SD Card
frp lock denied the installation. Get error: E: signature verification failed​
-> samsung smart switch and kies
both not working. I´m not even able to make the software initializing because it tells me that my phone (SM-G935F) is not supported... WTF....​
-> install CWM recovery via adb
I´ve tried to install an other revocery tool without success. I tried the ways via Odin and adb, both collapsing with the error of activated frp lock​
-> TWRP recovery via adb
Same like CWM. The Binary Upload is denied trough frp-lock​
-> Whipe cache from fastboot
I whiped the cache several times without anything changing​
-> factory reset from fastboot
It says that factory reset was successful but data could not be wiped. It also changes nothing....​
From my nooby perspective i would:
-> unlock the frp
-> install custom recovery
-> unlock signature validation
-> install via adb or sd card the newest Firmware
-> lucky guy
I´m really depressed/sad right now and have no idea what to do next. I spoke with samsung service and they told me to send them the phone so they can repair it. I hope that this is not ne final solution...
If there is any possibility to get the phone back to factory reset or any other working system i would be soo glad.
sorry for the bad english, it´s not my mother tongue
Thanks in advance and beste regards

LOL, didint read all but the part where the phone freeze after few hours on MM or even on clean Nougat firmware its a big sign that the problem is with hardware, just send the phone to Samsung so they could fix it and move on

I actually did. From my perspective there was no other way so i send it in. Really unhappy with this solution but i hope that Samsung Support will repair it. Maybe i was too naive with the android phone. i thought that i where able to totally delete and reinstall the system like i do with my computer. Now i will look for a good backup solution for the future ;D
Thanks in advance
I think you messed up your phone somehow... certain steps you described do worry me what you might have done.
Did you root/unlock your phone before? If yes, Samsung will happily return your S7 without even touching it.
Kies & Smart Switch do not work on rooted phones. Exception: Emergency Software Recovery and Initialization
Did you try flashing all four files (BL, AP, CP, CSC not HOME_CSC) in Odin at once? Did you try another PC / USB port?

Soft brick on a FRP S6 edge + (SM-G928f)

I have a FRP S6 Edge + and I tried to bypass this security lock folowing some totorials online. They didn't work because I assume Samsung already patched the software accordingly. I don't know what version is installed on the phone but I assume is running on Nougat since my attempts to bypass the security lock failed. So I've decided to downrade...
I've tried downgrading with Odin to 5.1.1 but it failed from the begining of the procedure and soft briked the phone.
Now it is displaying the following message: "An error has occured while updating thge device software. use the Emergency recovery function in the SmartSwitch PC software."
I can enter in download mode but I cannot install nothing with Odin. I've tried 5.1.1 firmware and 6.0.1 but it fails from the start. I've also tried 5.1.1 repair firmware package (4 files) but same, it fails. The only firmware that starts running on Odin was the latest 7.0 firmware but it also failed somwhere at 80-90%.
What now?
hey bud - i had this 2 days ago - luckily i sdorted it - its because you put oem locking off when you had a custom rom
what you got to do is - get serial number from back of se6+ or where ever it is - load smartswitch on your computer -
load it up and go to tools - emergency inatallation - put model number - ( this might fail - come out refresh your desktop and go back in )
then put serial number in the second box - it downloads the stock rom - but at least your in to start again -
it took me a whole day of worry and play just becasue you flick over the oen butoon -
try the above - it will work buddy
If not look for Bear on telegram and pm me and we will go through it together
Odin wont help you on this - you need smart switch from the samsung website - i install 5.11 - 6.0.1 - 7.0. lol - smart switch goes via your serial number and pulls the exact rom and recory system - cache - everything to fix your phone - good luck - you will sort it bud -

Samsung Galaxy A520F bricked

Hi there,
my wife owns or better owned a Samsung Galaxy A5. Due to many problems (battery drain, bloatware) with the stock rom, I installed Lineage OS 14.1 a few months ago. Now I just wanted to update the Lineage OS, selected in the update section the new version. The update started booted into TWRP and installed everything without any problems. After finishing the flash process the phone tried to reboot:
I heard the vibration, the white Samsung Screen appears, then follows a vibration and the screen is getting black, the white Samsung Screen appears, then follows a vibration and the screen is getting black, the white Samsung Screen appears, then follows a vibration and the screen is getting black, the white Samsung Screen appears, then follows a vibration and the screen is getting black, …
I'm still able to enter TWRP (Vol+-Home-Power) and the Download-Mode (Vol--Home-Power). In TWRP I tried to flash an older Lineage Build and also an upgrade to Hades ROM Oreo (including BL and Modem). The flash processes succeeded without any problems. But to bootloop remains.
The I searched the net for the original Samsung Stock ROMs. There's a big selection of ROMs on Sammobile, but I'm still struggling to get the download working . On other portals the offered stock roms fail to download (a 2GB file with 15kb/sec).
There's another problem: I don't have any Windows here. On Linux I did the most stuff in Heimdall. But I don't feel comfortable the unpack any tar.md5 files and unpack the partions and unpack the images … Samsung Smartswitch isn't available for Linux too. So the easiest way for me is to use TWRP (Version 3.2.3 is installed). I can access TWRP via MTP to transfer files.
Which chances do I still have to unbrick that garbage device?
(If I don't get it running, it will be the last Samsung phone we have ever bought. This Samsung crap is not even in a single piece comparable with my old Oneplus 3)
I have a SM-A520W that has been bricked it wont turn off only thing i can do is go into download mode but absolutely everything i try to send up into it thru odin is blocked i downloaded the latest firmware along with the 6.01 mm BL and nothing works. Its with videotron
