Can you boot your phone in CWM recovery?

You should charge your phone first.. Make sure your phone's battery is fully charged.

charge the phone, enter download mode while connected to a pc, flash a stock kernel with odin then flash the rom. does the recovery mode work?

Hello, first thanks for the answer, im sure the battery is fully charged, becouse i get 2 batteris off my friends and i asked them if the baterry is charged and them tell yes, and i can't get recovery mode, if i press +vol and home button and power button the phone start with the samsung model screen and power off on 3 seconds, i dont know what to do. Thanks

maybe your power button is stuck, or other button is stock

Get it repaired (talk to your phone company about this e.g. Sony), i think its the only way to fix your phone.:thumbup:

- try charging the accu externaly
- while on booting try combos of vol +/- and power button to access recovery menu
- dissasemble and check the buttons

just hold power button for about 10sec and it will power off.
power it on again, and make the update OTA

You're in download mode. Hold the power button for 10 seconds to turn it off.
Bootloader is hold both vol keys and press power

Hey guys, I used FlashTool and something went wrong. Ever since, My phone will only be a black screen when its turned on and I can't go into recovery mode. I can't work out how to restore it without. Please Please Help!?!?!?

Flas again with flashtool.
Before flashing press and hold power and volume up buttons together and hold about 10 seconds untill phone vibrate three times.Than star flashtool,hit flash and when you pop up windows show press and hold volume down button and connect phone to cable and flashing will succed.

Great New, I got it working again, Seems like battery life may have been a key issue here. Its loaded up, but got stuck on the blue musical bit and made some horrific beeping noise and keeps rebooting. Any help? I can't seem to get into recovery mode, Maybe thats just my method.

Bricked S8+ SM-G955F while rooting!?

Hello!
I tried flashing another ROM to my S8+. The ROM was downloaded from SAMMOBILE and I followed the instructions step by step. While flashing with Odin ( Odin was downloaded from the link they provide on their site ), 5 seconds after I pressed START the phone just powered off after I pressed the bixby button by mistake. Now, the phone won't even power on and the led isn't turning on when I charge the phone! What can I do? Worked so hard for this phone!!

I am from Romania and I installed this one sammobile.com/firmwares/galaxy-s8-plus/SM-G955F/ROM/download/G955FXXU1CRC7/213035/
I tried both of the above and nothing happens. Also, I get no led or charging animation when I plug my phone in. Is it RIP?

Was it fully charged when it when off?, maybe let it discharge overnight
Try to charge it with a different cable/charger
Make sure that none of the buttons are stuck, press them one by one to make sure they work properly
Press power on , plug it into your pc and see if the device is recognized
do all of the above with the SIM and memory card out.....
What setting did you have in odin....
What it was flashing when you pressed the bixby button?

Hi again and thank you so much for all the help!
I had around 70% battery life so there was no chance it went from 70 to 0 in 5 mins.
It can not discharge because it's turned off and I can't make it power back on
I was flashing the AP file and 3 seconds after I hit start in odin the phone just powered off. All the buttons are working properly and there is no SIM/memory card in it.
If I press the power button nothing happens...same when I connect it to my PC....nothing
The phone is dead and so am I ))

Hi
Just the AP file what about the other 3 BL , CP and CSC? and what Odin setting you had?
My best guess is that the hardware is in an undetermined state ..not necessarily bricked but it may be
Keep pressing the buttons , try to get into download you may get lucky and catch the hardware "awake" and let you get into download mode...if so flash the firmware again...all 4 files

If you are in the same base , Nougat to Nougat, flashing just one of them should not be too bad..but when changing base Nougat to Oreo...that is not a very good idea, is complete different firmware and they may not be 100% compatible
lets cross fingers and hope for the best

Hey, did you manage to start your device again normally?
I'm having the exact same issue and there doesn't seem to be any solution online.

Hello it's me (maicanvlad7) but from a guest account. It didn't start so I was forced to use the warranty. Depending on your location you might or might not be able to use the warranty. There is no software solution for this problem, none that I know of at least. Best of luck man!

Hey,
I have the same problem with the bootloop and the corrupted locking screen. I'm able to boot into download mode, but I can't figure out which system to flash. I tried several ones, but none of them worked... and I can't get back to the factory recovery. If somebody has an idea which recovery system could work I would be very pleased to know.
Software used to Flash: Odin
