[Solved] Boot loop after installing rom - Samsung Galaxy S8 Questions and Answers

I tried to install the batman rom. I must have done something wrong, but now I cant reboot in to system, nor can I reboot into twrp. I tried installing twrp again and it fails when following the instructions. Now I only get a bootloop
I installed batman rom with defaults, It changed csc to german.
I have a sm-g950FD
Followed this guide:
https://www.youtube.com/watch?v=VTi3uBkpJic
Downloaded the bootloader QF7
flashed it via odin.
Was able to flash the twrp but cant boot into twrp
I followed this guide to completely reset my device:
https://www.youtube.com/watch?v=2y0ZZxcNVnE
and nothing
it continues to bootloop. Can anyone give me some insight?
Edit Downloaded this firmware:
SM-G950FD_1_20170920085414_7s78fc4emo_fac from http://updato.com
Flashing now lets see what happens...
Edit: Nothing worked. I think I am completely stuck Any suggestions?
I am not sure which firmware to flash? I dont know my pda version any way I can find out?
It is a sm-g950FD and when I first booted it the language was in spanish. Looks like there are very few sm-g950FD made for the spanish market. 3 guesses: Bolivia, Philippines, Brazil (I know they speak Portuguese). Does it matter which region I get the firmware from?
Installed the Bolivian G950FXXU1AQF7
Weird series of events, I was just about to give up, while handing it to the postdoc in my lab I pressed either power + Vol up or power + Vol down (I don't remember which one) and suddenly I see the little android with the spinning icon on a blue screen. Essentially a miracle WTF?

Same phone same issue for me. I had to get the original firmware from sammobile site and use Odin to flash the back to stock. No matter what with other ROMs I get bootloops.

Did you manage to solve the problem. I also followed the guide, odin pass, but the phone after reboot goes into bootloop again.

Arg, possible brick but can get into download mode and connect with Odin

I did something stupid and flashed this Bootloader with odin on my Sprint GS5 US G900P. After the flash seemed to go ok it just re-boots and stays on the Sprint Logo. I can Vol up and down to get to recovery and Download mode but I'm not sure what I should be re-flashing to get my phone to boot up again?
Can someone help please?
I re-flashed my boot to NE5 Galaxy_S5_spr_Stock.Kernel_NE5.tar from here here. Now it gets past the logos and starts to load but freezes the little google loading animation and then goes to screen black
try this
as you can enter download mode
just flash stock firmware
before boot phone go to recovery mode (after flash)
wipe all
wipe data factory reset
wipe cache partition
reboot
Thanks for the suggestion AEkiz. I couldn't find a stock firmware. Links seemed to be dead around here and I couln't find it on the Samsung site.
However this has semi-worked for me:
I flashed 5.0 imgae SM-G900P_OA6_FullRestore.exe
Install seemed to work just fine.
Then I reinstalled my Backup of (Mystery build) 4.4.2
Installed Galaxy_S5_spr_Stock.Kernel_NK4.zip form the file All_Kernels_thru_OA6.zip via Odin
Then my device just booted!
But there are some issues:
1. My device still says it's running OA6 even though I flashed NK4. Oddly enough it WAS on NE5 in the first place but when I tried to flash and NE5 firmware it got stuck on the Google logo. now I'm just confused on all these Nxx versions.
2. My fingerprint scanner is now dead.
3. My camera has a bunch of funky artifacts so I can't really use it anymore.

S5 SM-G900F bootloop, nothing worked

Today my father's Galaxy S5 SM-G900F freeze after connecting to PC when I tried to copy some photos to PC. After that it started bootloop. Phone was ALL STOCK, no root, no twrp, no nothing without original latest android 6.01 directly from Samsung.
First thing I tried was wipe cache and factory reset. Nothing changed. Then I tried to download new firmware via Kies3, it took some time, update succesfull but still bootloop. Next I tried to put latest firmware G900FXXS1CPI6_G900FXEO1CPE2_XEO via Odin. Everything fine, succesfull but still no success, bootloop. Then I flash latest twrp on it. Twrp boot fine, I tried wipe, nothing changed. What can I do? Phone is bricked permamently or there is something I can do? TIA for any clue! I've read tons of forums and sites and everywhere told to flash firmware but it not worked for me
update: I also discovered strange thing when I tried to flash via twrp. After few second flashing (blue bar does not go forward) phone reboot itself and stuck on Samsung logo.

I think you must try a repair rom its come multi package boot loader and modem and ap and thetr is the pit file and be sure to get the proper one for your device and try to flash via odin
Thanks but it didn't work for me. I just tried 4 files (BL/AP/CP/CSC) and 5 files (+PIT). Everything success in Odin, recovery back to stock samsung but phone can't boot. Few times restart then stuck on samsung logo. Is any other way to try?

Bricked S8 950F after Root and Twrp Odin Says fail

Hi everybody Guys I need some help think I gone crazy My S8 950f Get bootlooping in Samsung S8 logo with red letters above it says only oficial binaries allowed. Something like that. I go to Odin To restore it back to stock with stock firmware 8.0 and Odin says fail when start to flash boot IMG when I see this I almost start to cry and we'll I tried so many firmware and Any does seems to work Now I got Beautiful 350 bucks brick phone. Somebody know what it's happening?
In the download screen says sv firmware check fail Bootloader
(Sorry for my bad English I using Google translate)
Please help
donot worry its a soft brick.. flash twrp and as soon as odin say successful and phone turns off imediately prss bixby + power+vol up....it will take you to recovery....download a rom and flash it
Just a question, but did you put your device into download mode before trying to flash via Odin?
It´s like said soft bricked, so any official stock Rom should work with Odin.
No need to flash TWRP first as each official ROM comes with stock recovery and will overwrite TWRP anyway when flashing it. But you of course can give it a try. If you can´t flash a firmware for some reason, i would try a different one. The one you are having might be corrupted.

IMEI number lost after flashing ROM (no backup)

I know there might be another similar topic but I couldn't find any help so far.
Basically two days ago I flashed custom ROM on my phone, I didn't make any backup. At first it worked perfectly. I decided to flash ROM again and formated my phone and found out that EFS partition was lost. I didn't get any mobile data and my IMEI number was lost (0000000). I've read that IMEI is actually stored on some chip so is there any way to restore it back? My phone is Samsung Galaxy A5 2017. Any help will be appreciated.
Trying to flash latest stock rom from sammobile but after flashing it with odin it starts bootlooping and saying "no command" again and again. When holding power + home + volume up I can NOT access recovery. Any solutions, please?
Anyone? Is there any solutions for my problem??
Is it possible to downlaod EFS file for my phone and somehow change IMEI in the file?
just flash stock rom, i did on my galaxy ace i flashed custom rom and imei gone, after stock flashed via odin imei back.
Thanks for your answer! I tried indeed flashing latest stock rom from sammobile with latest odin. But when I bootet phone up it said "no command" with dead android logo and kept bootlooping. I can try different version of rom, maybe it helps.
Still my problem is unsolved. Any clues what to do would be great.
You probably flashed a wrong firmware which is not for your variant.
Can you remove your battery? If so remove it and put it back and enter download mode by pressing volume down,power and home button. Afterwards, find the firmware which is for the specific variant of the phone. Only get the "HOME_CSC" version or else you will lose all you data. In odin, if it says added, flash the stock firmware and see if it boots to the system. If you could give me your variant, I could help and give you an even more detailed guide.

Cant get into TWRP/Recovery after CFW flash

I'm not a complete noob, but also haven't done anything regarding phone flashing in a while and this technology seems to change very quickly, so hard to keep up....
The Issue
I cant get into Recovery (Power + Bixby + Vol Up), my phone just shows the Samsung Logo and stays that way.
Forward
I have a SM-G950FD
I have no clue what the CSC code is
I am able to get into Download mode
I have a recent backup of EFS, CPEFS, and RADIO partitions
Odin does detect my phone
OEM Lock is OFF
What I did
I cant remember the sequence of events very well, just that I was on Nougat (I think) and wanted to try newer roms
I tried LightROM ([Samsung][ROM][PIE][9.0][13-July-2019][S8_S8+_F_FD][v21]LightROM.zip) which worked OK but I found out I wasn't rooted
So after using TWRP to flash a few more things, like SuperSU and still not getting a rooted device I decided to try a different CFW
I tried to install (hadesRom_PIE_Stock_v9.0.zip) from TWRP (This did not boot into the ROM)
I then tried (BatStock-Rom_SM-G95XF_V1.2.0.zip) from TWRP (tHis also did not boot into the ROM)
I then probably tried a few other things...
My phone now only starts with Samsung logo screen, and I cant get to Recovery/TWRP
Messing with ODIN
Only thing here is that I tried to install the latest version of TWRP with ODIN. While the flash succeeds, I still cannot get to Recovery.
I probably did try an older version of TWRP first (such as twrp-3.2.1-0-dreamlte.img.tar)
and I probably tried an older version of ODIN earlier too (Odin3_v3.12.5)
Last thing I tried was to flash latest TWRP (twrp-3.3.1-0-dreamlte.img.tar) with the latest ODIN (Odin3_v3.13.1)
Anything I can do to get TWRP back?
Thanks so much to everyone who keeps up with this stuff
Ok, made some progress. In order to repair phone, just need to use ODIN to flash (AP, BL, CP, & CSC) via Official Samsung 7.0 Nougat ROM.
Then after I install TWRP (twrp-3.2.1-0-dreamlte.img.tar) phone goes into bootloop.
Re-installing 7.0 Nougat to repair recovery.
Is there a magic combination to installing PIE + TWRP + SuperSU ?
Downloaded a 9.0 Pie Samsung Official from Austria (G950FXXU5DSFB_G950FODX5DSF1_MAX.zip) and Installing.
This guide looks promising https://www.androidinfotech.com/root-samsung-galaxy-s8-sm-g950f-pie/ . . .
the guide was very helpful. I now have Android 9.0 Pie + TWRP + Magisk (instead of supersu)

If you get "Cannot mount /data and unable to find crypto footer." when you try to install the Big 3 (Magisk-v19.3.zip, no-verity-opt-encrypt-6.0.zip, RMM-State_Bypass_Mesa_v2.zip
