S8 plus G955F won't boot after switch\odin - Samsung Galaxy S8+ Questions & Answers

Hello guys!
Two days ago I was punched by a problem with my g955f: I bought it from my friend, I wiped it completely and I wanted to update it via Smart switch.I flashed the stock firmware with switch, the process was 100% succeded and then the phone tryed to boot up but everytime he pass the first screen with s8 plus galaxy text, he arrives at the second bootlogo with just the samsung text and then he restart itself continuously.
I flashed also a firmware with odin..I fully charged the phone and then tryed again with Smart Switch but the same problem still persist.I don't know what else I can do, I have no warranty because the back pannel is broken so what else I can do by myself? Anyone has been met with this strange problem?
Thank you guys !

However there are all the directions on YouTube, try to see that you find, I also had this problem but I only tried with Odin. You have to download the right firmware for both the model and the nation, following the directions with Odin you should succeed.

Hello, thank you for your reply !
I already tried with the right firmware by searching it after csc and pda, I tried with anything else, I tried with smart switch but everytime the flashing process ends up successfull but the phone is continuously restarting, not even a first boot..

hello
is it fully charged?

Hello,
Yes it is fully charged and he keep restarting until he drains the entire battery

Have you tried installing twrp with odin? Or is twrp already installed?

I tried to install twrp and then flash a custom rom.Everything went succesfully(the flash process) but when the phone tried to boot up for the first time it went in the infinitly restart..
I mention that I choosed the corect twrp for my g955f.

There is only one way to start in twrp. Hold down the volume button - and power, the screen shuts off for 2 or 3 seconds, then you have to press volume + bixby and power at the same time until twrp appears. Then install it as by procedure. I did this and it works

if you have no guarantee...
you can try a combination file and see if it can boot
just ask google for one for g955f

I tried with the combination file one day ago..but I ended up into a screen like "KERNEL PANIC MODE" .He is entering in this screen when he's trying to boot up.

Thanks Sushant, I've checked that solution before but the PC doesn't view the phone because it is starting...
Thank you. I am not sure whether this will work but try this.
Pull the battery and place it on its position. Now press the Power and Volume Up key simultaneously. There a menu will appear I am not getting the controls but I think Volume Up is the selection Volume Down is used to move the selection(but I am not sure about control) navigate to the recovery mode and hit the selection button (I am not sure what the selection is, but you will find it as soon as you get into advanced booting)
May be this helps, fingers crossed, praying for your device

"Unbrick" your phone, easy.(Wiped OS with TWRP) Stuck on Huawei Logo help

Hello Guys,
since i saw a a bunch of posts with: "Help stucked on bootlogo" , "wiped OS", etc. ,
and i've done it by my selfe ^^ ,
I found the answer, so you need a working TWRP, and a SD-Card with a good /dload folder.
Go to the TWRP with power on key and at the same time vol + (up).
Now go to Reboot and Bootloader
now you flash the standard recovery.
Like you flashed the TWRP just with the restoration Recovery.img .
All you need is inside of this link provided by Hirs_E_Fruit from his Root Guide.
If you have finaly done flashing the stock recovery you can shutdown your phone and start it with power key + vol+ and vol-
all three at the same time for a solid amout of time idk about 8 sek or so i normaly release the power key after 5 seconds +-.
yea then you should see a blue circle a usb plug in middel of it and some chinese writing.
Hope this will help someone
Have Fun and Good Luck

Hard bricked my Samsung Galaxy Gt-I 8262

I wanted to install lollicop ROM that I downloaded from a thread in this forum.
It happened when I flashed TWRP by Rashr App and rebooted my phone
It got stuck on screen that's saying
[ODIN3]
PRODUCT: GT-I8262
VERSION: I 8262XXBNH1
HW REV: 8
CUSTOM BINARY DOWNLOAD: NO
CURRENT BINARY: SAMSUNG OFFICIAL

and below it a green Android logo followed by
Downloading......
Do not disconnect USB cable during the software update!
I tried everything,
Volume up+ home+ power
Volume down+home+power
Removed battery
Connected to PC with kies installed but Odin couldn't detect it so can't install recovery from PC
fastboot is not detecting my device
installed latest drivers for Galaxy core but still nothing
Please show me a way if I could do anything with the help of phone or my PC
I don't want to change motherboard guys please help:crying:
This happened to me. You might have gone in recovery using rashr. Just use volume dn+ home + power until you see warning keep holding vol dn and home but leave the power when phone vibrate.
Note - keep holding the two until you see a warning and press vol up on warning. Odin will detect you
---------- Post added at 09:36 AM ---------- Previous post was at 09:36 AM ----------
But You need odin
---------- Post added at 09:37 AM ---------- Previous post was at 09:36 AM ----------
And restart using it
---------- Post added at 09:37 AM ---------- Previous post was at 09:37 AM ----------
If works pls like
finally solved it
if other users facing same problem here is the solution stepwise
1. install samsung drivers from the original website of samsung only or from this thread http://forum.xda-developers.com/showthread.php?t=961956, there are a lot of drivers available on the internet don't pay attention on them, they don't work
2. download odin latest version
3. go into download mode- switch off the device
long press volume down+power+home button simultaneously, when the phone vibrates or something comes on screen, leave all butten,
you'll see a screen with two options
1. continue
2. restart phone
press volume up key for continue, now you see a logo of android and downloadin on screen-- hurrey- you're in download mode
4. connect your phone to pc with an original data cable
5. odin will detect your device where the ID is written, if it doesn't change port or usb
6. install twrp recovery on your phone with odin, download it from this post its working http://www.techdroider.com/2015/01/cwm-twrp-update-galaxy-core-i8262.html. chose PDA or AP option
7. when the odin displays pass disconnect phone
8. go into recovery mode- long press volume up+power+home all simultaneoulsy
when the logo of smasung appears leave the power key but keep pressing the volume up and home key
9. now you're in recovery mode, choose the download stock or custom rom from sd card,
there are other method too but i prefer this one, bcz its hasslefree and once you've installed custom recovery you don't need pc or any other thing to update or change your rom or whatever plus twrp supports touchscreen.
Thanks twrp and XDA for saving my money
WoW Alhamdulillah thanks brother :*
I have the same problem with you
You have saved my life and my money ^_^
ı have this problem but if ı do this will ı lose my data ??

S6 Bootloop, No OS, No Home Button.

Hi,
I have an SGS6, SM-G920I, I have the phone for about a month with Android 6.0.1 on it, rooted with CF-Auto-Root. About 2 days ago, I decided to unroot the phone because I never used an app that need it, so, I did it from SuperSu app, after that, the phone keeps in bootloop.
I want to flash a stock rom, I already download it and odin 3.11, I dont care about pictures or anything else, but, my problem is that home button isn´t working, so, if I press vol down + home + power, it only recognize vol down + power, and because of that I cant pass the warning screen, neither vol up nor vol down works.
Is there any other way to pass the warning screen in download mode, I can only boot in recovery but non option allows me to flash rom.
Thanks in advance..
Yes. Just need just domaged usb cable. And make like this yourself.

Also recovery is option, boot into bootloader. It is download mode. Meaby it works for you.
Gonna try this, thanks for answer.
Access Download Mode from Recovery is not working, already try that, but phone keeps stuck in bootloop, thats weird but it happens since I have the phone

H830 bootloop please help

i use magisk module and ,y phone cant boot normally. bootloop on t-mobile screen. how i can enter twrp?
You enter Twrp the same way you enter the stock recovery. With phone off press and hold the power and volume down button. As soon as the first screen pops up (i believe its the lg logo) continue holding volume down but quickly release power button and then repress and hold it down again. Then follow the prompts click yes to wipe phone, instead of wiping the phone it'll put you into TWRP.

Some Magisk modules are only for certain phones or OS. I had the same problem after installing a module that was supposed to help the gpu. The dev didnt say it was for a specific phone or OS, but i assume that it was. Always make sure to read the notes of the module.
