Samsung S7 Won't boot up - Samsung Galaxy S7 Questions and Answers

Hi, my samsung galaxy s7 doesn't boot up after flashing stock firmware. In the past days i've successfully installed twrp and lineage 16. After some problems due to making some apps as system app. I've tryied to reflash the stock firmware with odin but it didn't get past boot logo. After trying some other times my phone decided to die without any possible to boot up in download mode. The only sign of life it has is when i plug into a computer and it says "an error has occurred while updating the device software", it suggests to use smart switch for an emergency recovery but the program doesn't recognize the phone. What can i do?

Can boot in download mode but no recovery

Greetings,
When I was flashing via odin stock rom somehow it got stuck on setup connection and I had to close it. Since then the tablet wouldnt boot into recovery mode and wont boot at all. It goes to first samsung logo and gets blank. I tried flashing stock roms even with options repartition via odin in download mode but no luck.
Any insights people?

I have this same problem. Bump.
Hey guys, I only suggest the following, cause I had the same problem after flashing via odin.
In fact it happened to me more than once since I forgot the solution after a while ...
Make sure you unplug the USB cable from your tablet before trying to get into recovery mode.
That did it for me both times - once with my S4 and just recently with my Tab 2...

[Q] Cant flash and overwrite with stock rom on M919

I need help
I have a Tmobile Galaxy s4 M919.
After the 4.3 update, i am not able to completely flash a stock rom in order to have my phone working again.
Tried root, tried CWM ot TWRP, Odin stock, Kies, but every attempt got stuck for ever on the boot logo screen with blue letters on the left hand up corner saying recovery booting.
I can't access download mode but not recovery.
Only onceworked, and i could flash thru KIES and the download screen after that shown:
System Official Samsung
Binary Official.
After that i start to have an issue with SIMCARD non detected, and had to restart and never worked again.
Seems like Knox is dealing with custom rom or bootloader and keeps on bootlogo screen.
Any help will n]be very appreciated.

Best thing to do is use odin on your pc and get the stock rom from samsung or another source, then completly flash it so it will wipe out you phone completly and then reinstall stock. This happened to my m919. If you need more help on how to completly replace the stock rom using odin there are plenty of videos that show you step by step. You just soft bricked your phone so it's fixable.

I have flashed several times via odin and kies, but everytime i still with Binary Official and System Custom.
Seems like the flash does not overwrite the kies bootloader, thats why i am stuck on boot revovery.
Once it worked, the system and binary became official, then i flashed knox free stock rom via recovery.
As i told, i can acces download but not recovery.
Does anyone know any knox free stock rom flashable via odin???

[Q] BOOTLOOP/ (maybe?) hard brick issue

Phone specs:
Samsung Galaxy S3 Verizon SCH-i535
It was already running KitKat 4.4.2 before I rooted
This is my first time rooting and flashing ROMs to my Samsung Galaxy s3 and I have bricked it. I'm pretty sure it can be salvaged but have yet to find anything that works.
I have written the long version for those who need it, but the short version is that I screwed up and can no longer boot into recovery mode or normal mode, I'm not even sure if Download mode is working, and my device isn't recognized by Kies or Odin on my PC so I cannot yet do a recovery from there.
As of now my phone only boots into Odin Mode (NO recovery, NO normal boot, device NOT recognized by computer programs like Kies and Odin) and gives the following info:
ODIN MODE
PRODUCT NAME: SCH-I535
CURRENT BINARY: SAMSUNG OFFICIAL
SYSTEM STATUS: OFFICIAL
QUALCOM SECUREBOOT: ENABLE
BOOTLOADER AP SWREV: 2
and displays the yellow triangle error and says: Firmware upgrade encountered an issue. Please use Software repair Assistant & try again.
I tried to use Samsung Kies which has an emergency firmware tool but my device will not connect and become recognized by the program.
This is pretty much where I'm stuck.
Keep reading if you need additional info.
Steps leading up to problem:
I was able to Root the device succesfully
I then downloaded the latest CM11 package (cm-11-20140217-NIGHTLY-d2vzw.zip) and Gapps
I also downloaded the TWRP recovery img (openrecovery-twrp-2.7.1.0-d2vzw.img)
Once I had these downloaded I got the app [ROOT] Rashr - Flash Tool
I opened the app and tried to do a backup but I'm pretty sure it failed, or at least it said it failed. I couldn't find out how to check, but was not worried since I have already backed up my important files to the verizon cloud.
On the app I went to recover using other file and found the TWRP recovery img I downloaded.
From here I booted into recovery manually, but it did not bring up the TEAMWIN screen for TWRP like I've seen in other video tutorials so I rebooted into normal mode went to the Rashr app again and followed the prompt to do a Recovery boot using the TWRP img.
THIS IS WHERE THE PROBLEMS BEGAN:
It began to lead into recovery mode but it gave a message that said something along the lines that I have tried installing a custom OS and to take my phone to the nearest verizon store.
I turned it off and tried to boot back normally but got the same error.
I tried to boot into Download mode and was successful! So I thought yaay!
Read a tutorial to reload a stock version of android here: http://forum.xda-developers.com/show....php?t=2586319
I followed all the steps but when i got to 7. which said You should see your phone under ID:COM (you should also see it has been added in message) I was not seeing my phone there. I figured it may be OK since I was able to install the drivers so that meant the USB was working so I went ahead and ran Odin to recover Jelly Bean 4.3 onto the device.
My thoughts and guesses as to what the problem is:
I think that it may be because I was already running 4.4.2 and/ or didn't have the proper bootloader when I tried to do the TWRP recovery.
Am I on the right track? Thanks for any help!
You're not bricked if you can still get into Download mode. First of all the Verizon S3 on 4.3 or later has a locked bootloader - you can't install a custom recovery, and only TouchWiz based ROMs are supported using Safestrap. In order to get back up and running you need to see this thread and use the Verizon Utility, or use the Odin method with a stock 4.4.2 ROM seeing as you're on 4.4.2. However I'm surprised your computer doesn't recognize your phone, that almost sounds like more of a drivers issue than anything if your phone still gets into Odin mode. As cliche as it sounds - have you tried rebooting? It may help with a driver issue.

tried to install a 6.0.1 rom and ****ed up my phone so bad.

downloaded twrp 3, was running 5.1.1 on my phone and rooted it. tried to flash a rom and got stuck in a bootloop, now I cant boot into twrp, or anything for that matter. All i can do is hold volume down and power and home and try to ODIN a new bootloader or such and it just fails. what do i do? but when I try to boot into TWRP it goes into a blueish screen with a White exclamation mark saying "An error has occurred while updating the device software. Use the Emergency recovery function in the smart switch PC software. I tried to do that but it didnt even recognize the device. At this point i dont care about the data, I just need a working device
Okay, so I attempted to unroot and flash the stock 5.0.2 software and I got a error on the download screen. It says SW REV. CHECK FAIL. DEVICE: 3. BINARY: 1.
If you have no knox install MM official then flash this kernel tar file (AP) https://drive.google.com/folderview?id=0B40ItdHKfkyQcTA5bnRPWDg0X28&usp=drive_web#list it will boot to mm 5min :good:
Btw you cann downgrade from 5.1.1 to 5.0.1 you just go up not down

Happened to me a lot of times in the past few days trying to get MM, for some weird reason flashing Unikernel always works for me (takes me to recovery screen after, then i select 'reboot now'), and all my data, apps etc are still there

will try and update. thank you. didnt work.
Okay guys so now I need a ROM to flash using ODIN. I tried to download from sammobile but the speeds are too damn slow. What I tried to flash was this file " G920TUVU1AOCG_G920TTMB1AOCG_G920TUVU1AOCG_HOME.tar.md5 " and i got the error 3 to 1.
Download Samfirm from here, XDA itself.
Run samfirm, enter model as G920F and your region code.
It will download from Samsung servers, so high speed.
Now flash using Odin the downloaded file by putting the phone in download mode, (vol down+home+power on).
How did it happen?
Did you try to flash the VOD 6.0.1 and got stuck towards the end at hidden.IMG failing the process?
If yes, then its a two minute job. Just open the 6.0.1 tar archive and look for hidden.IMG extract it anywhere and rename it from "hidden.img" to "hidden.img.tar".
Note flash this hidden.img.tar as AP in download mode, your phone should boot.

Stuck at Boot Loop, Need Help..

Here's the story,
This is my dad's phone. He just recently bought it. Out of nowhere, it stuck in bootloop (screen only show phone's model). He asked me if I can fix it.
I tried recovery mode and failed. It can't enter recovery mode. So I should fix it via download mode, right?
The thing is, I don't even know the firmware's phone. So I'm assuming it is Indonesian, cause I live in Indonesia.
I flash using odin and it passed but the phone still stuck.
When rebooting, the boot screen flashing 3-5 times (show phone's model - black screen - show phone's model - black screen - and so on), then stuck at boot screen again.
This is weird. So I thought maybe wrong firmware. I tried India and Phillipines (global) firmware too but the problem still exist.
I don't know how to solve it. Please help.

try this guide I made for restoring stock firmware from Samsung sever with the smartswitch app for Windows.
http://forum.xda-developers.com/galaxy-j7/j700t-development/how-to-restore-j700t1-model-to-t3423455
but you NEED YOUR SERIAL# AND MODEL # of that phone!
Fix # I dont know - if it works
Try this if it helps....
You will need ( link unavailable due to my little amount of posting and not using this account):
Galaxy J7 USB Drivers for the phone
The stock ROM for the phone (exact firmware)
Odin
First install Samsung Galaxy J7 USB drivers on Windows PC. Then Download the Samsung Galaxy J7 Stock Firmware from the link above and extract the folder on your desktop.
Download ODIN flash tool to flash the firmware on your phone. Extract the folder and you will see the ODIN.exe file in the folder.
Now Turn off your Galaxy J7 and Boot in download mode.(Hold down Volume Down + Home + Power button at the same time)
Once your Galaxy J7 is in download mode. Connect it to the PC with USB cable and run the ODIN.exe file on your desktop.
If everything is right and drivers are working properly. You will see the blue box on the ODIN screen, if not reinstall the drivers again and reboot your PC.
Now select the AP option from the ODIN screen and select the firmware file that you extracted
Hit the Start button from the ODIN screen to start the flashing process.
Once completed you will see the PASS messages on the ODIN and Phone will reboot automatically. Now you can disconnect your phone.
IMPORTANT:. If your phone is still stuck on the boot loop or in the Samsung Android Logo, then turn off the phone and reboot in recovery mode. TO do this Hold down Volume Up + Home + Power button at the same time. Now from recovery select Wipe Data/Factory Reset and after that Wipe cache partition. Now reboot you phone. If you are using a custom recovery, just wipe data/factory reset and wipe cache partition again.
DONE!!!! You unbricked your Galaxy J7. Now your Phone is running the stock ROM. Check it on the setting. ENJOY..

Try to install TWRP on the phone, then try to wipe out the stock firmware that installed. And of course, reinstall the original stock firmware that come on that region. Its actually came from Indonesia, so be sure to install the right one.
