[HELP] phone stuck in bootloop after unsuccesfull custom rom installation - Galaxy S6 Q&A, Help & Troubleshooting

i have a 920f on which i had the xef 7.0 android (it is a phone bought from orange romania, sim locked and the csc was oro)
i installed twrp on it and after that i rooted it by flashing a zip file with twrp
then i wanted to install a custom rom. i copied the file on the phone but i wasn't paying attention and the copy process stopped in the middle of it but the file was still on the phone. wiped everything that was asked to wipe then proceeded to install the zip only then to find out that the installation ended after about 30 seconds. i tried rebooting and i'm stuck in a bootloop. even though, i can still enter download mode and in the recovery but because i wiped all those things(everything except internal storage and usb otg)
i know that i should have checked to see if the file was being copied fully but even now when i connect the phone to my laptop in the recovery to copy the zip, it still does the same thing. i tried using another usb cable, another usb port and even another laptop but the copy process still stops about halfway trough.
right now i'm downloading a stock rom and gonna try to flash it with odin. what should i do?
any help is appreciated

Download a 7.0 rom from: http://updato.com/firmware-archive-select-model?q=g920f&exact=1
Flash it with ODIN (AP)
Boot device, it should work
If this doesnt work and you know what you did wrong just download samsung smart switch, do an emergency firmware recovery en start over again

Nexus S won't boot to OS

I have the Nexus S from Telus.
It was rooted, unlocked, running CM7. However I've been having issues with it freezing and decided I want to go back to the stock rom.
I ended up downloading what I thought was stock ROM for my phone (Stock GRH78 Nandroid Backup in this Tutorial http://forum.xda-developers.com/showthread.php?t=884093) however after it flashed my phone, I ended up with a phone which was essentially stuck in Airplane mode, would not connect to Telus. I'm guessing that it has the wrong radio for my phone/carrier?
So then I ended up finding a zip file someone posted Stock-GRJ22-i9020A-unsigned which should have worked, I ended up flashing the zip file from recovery.
It said it installed fine. Rebooted, and now the phone just cycles the Samsung Loading screen endlessly.
I tried to go back to recovery, and it gives me yellow triangle with !.
Is there any way to flash the recovery image back to the phone?
I plug the phone in and the PC won't recognize a device.
I installed the Android SDK
Ran the command adb devices, no devices attached to the PC.
I tried fastboot devices - blank
I don't know how I'll be able to get files back onto the phone SD Card for flashing etc...
I had the exact problem two days ago...flashed an image that jacked my phone up. Wouldn't boot past the google logo. Sat there indefinitely.
Read this thread and see if you can get it work. In a nutshell, you need the PDA net drivers installed. Since PDA net can't install the app on your phone (because it's not booted into an OS) leave the install program in limbo and voila, fast boot will work. From there, push the recovery.img (google Clockworkmod recovery image), boot into recovery and you are off to the races.
This is, of course, assuming you already have a ROM image on your internal SD card you can flash to get back up and running. I'm not sure how to install a .zip image ROM if you can't gain access to your SD card.

Good luck, I know the feeling. It blows.
Ah, just found out how to install a file on a phone that won't boot.
You do need to flash CWM recovery first though.

Good news! I tried a factory reset/data wipe and rebooted the phone.
It doesn't hang anymore, all functions restored and the phone is working on Telus again!
I guess I had to format data, clear cache, before the flash of the rom.
So relieved.
Issue has been solved!

[HELP] Soft-bricked Galaxy S6 G920F [Solved]

Hello everyone. So, let's start by explaining what I have did.
For a while I had the XtreStolite Odex 2.0 edition and I wanted to try out other ROM. I have factory reset-ed when I was installing the ROM using TWRP and I somehow managed to delete all the phone's internal stuff, but I can still boot to TWRP or download mode.
I have tried to flash stock firmware using Odin 3.10.6 ( running as administrator too ) and when it gets to sboot.bin it fails right away. I have tried using Samsung Smart Switch PC Software, tells me my device is unsupported. If I try to manually find my model using the S/N, the software fully downloads then gives me an error.
I have tried to ADB sideload from TWRP Advanced menu, whenever I want to flash for example xtrestolite odex zip ( named rom.zip for short ) it goes "serving:... 21%" and gets stuck. If I try to push a zip it says "error:closed". I am no big expert in ADB, I don't know how to install the latest version, and I can't download the full Android SDK because my internet is very slow. I had Bootloader and Modem 5.1.1
I am looking for a way to move the XtreStolite ROM zip into the phone's memory so I can boot to TWRP and install the ROM. I've seen something with OTG Cable and USB but I have no real knowledge of these. If it comes as a last resort, if someone could briefly explain me how would I manage to repair the phone using the OTG Cable and USB stick.
I also have a Nandroid Backup on my PC but I don't know how to move it to the phone's storage, because it's well, bricked. When I'm trying to copy files over Mount option in TWRP, it says that it cannot copy the file, the device may be disconnected.
I had Bootloader and Modem 5.1.1, also Windows 10. I can go back to 7 or 8.1 anytime it's needed.
Much appreciations.
EDIT: I actually repaired it by flashing a stock firmware downloaded from xda ( God bless you whoever linked the mega.co.nz stock fw link ) . Thread can be deleted.
You can also flash these via odin.

[Solved] Fully wiped phone(D6633), no recovery, fastboot command not allowed

Update: So thanks for all the help guys, i just downloaded a firmware from Flashtool's XperiFirm and flashed it to 23.4.A.1.232, I'm just going to apply root and recovery and i'm set.
Hello, I was using a stock based 5.1 ROM when i tried to change the theme and the screen just went black i was receiving messages and stuff so i knew the ROM was working but it had no interface i tried waiting to no avail so i restarted the phone and saw the screen still black. Since i had just recently installed the ROM and did a SD and internal storage wipe for a fresh start, i just said screw it i'll just use my old twrp backup and booted into recovery HOWEVER before flashing the backup when i went to do "Advanced Wipe" i must have accidentally ticked the wrong thing because being a moron i restarted the phone and i suddenly had no recovery or rom. So now when i turn on the phone the only thing it's showing the Sony logo in the middle and "XPERIA" in the bottom.
I can still access fastboot and flash mode.
I started up fastboot and tried to flash the dual recovery kernel but i kept getting the "Command not allowed" error.
I used flashtool to Relock/Unlock my phone and still got the same error.
I re-installed all the drivers still the same error.
I tried different USB ports and cables.
I know i can flash a firmware using XperiFirm from flashtool, but my internet connection is slow, has frequent disconnects that restart the download and the ISP charges like 5$ for every Gb i download, also i dont like to wait a day to download a firmware that i'll change in a few hours.
If you can help me get twrp in my phone i'll be a happy camper , if not i'll just have to flash the firmware :|
Thanks in Advance, Dan
UPDATE: i made and ftf from a ROM i had laying around and flashed it with flashtool but i've still got the same issue with no improvement. I just cant get why fastboot flash commands arent working.

Troubleshhoting ROOT problem, please help!

So here's the thing. I have a Galaxy Note Edge SM-N915T (UVU1ANK3) I wanted to root it and am stuck in a state I cannot seem to get out of after searching all over the internet for. I got TWRP on the phone but that's about it, the interesting thing that I challenge anyone to help fix is how to get SuperSU on the internal SD from my computer since I cant get the phone to go past the Note Edge startup screen (I'll come back to this) and when I plug the phone into the computer it won't recognize it to pull up the storage. The other problem is in TWRP, it says there is no OS installed so I cannot do anything on the phone at all other than TWRP and the flashing screen. When I try to install ROM's I get an error code of fused 2> binary 1 not sure what all that stuff means.
In Summary:
1. No OS installed
2. SuperSU unable to put in internal SD
3. Fail to flash ROM's to phone.
Any help would be greatly appreciated!
Have you tried flashing via adb? And tell me whats the version of yor twrp btw. You might need to switch in cwm recovery though as that one worked for me in my gsmart phone

Click to expand...

Okay I'll start from the important to the less.
1/3.No OS installed:
Make sure you are using the latest and the correct twrp for your device (TWRP 3.1.0) through odin
Here: https://forum.xda-developers.com/attachment.php?attachmentid=4092902
Or twrp recovery -or any other custom rom-
https://forum.xda-developers.com/attachment.php?attachmentid=4092901
And you can try installing a custom ROM through it
P.S you can't flash official tar or tar.md5 files through twrp
Or get into download mode and flash official frimware with odin
2. Rooting:You got 3 options
-moving it after flashing the firmware through odin -or a custom rom-
-puting the SD card in another phone to move the zip file to it
-using card reader to move through pc
works also if you couldn't port the right zip custom

cant install firmware on s6

So i tried to install a new kernel,but things got messy,the kernel installed,but when it booted it gave me a black screen,could only hold the power button to open the turn off,restart features.I tried to flash a new firmware with odin,but it just fails to flash,if i boot into recovery twrp and try to copy somehting on my internal storage it gives me an error saying my phone is disconnected or not responding,then i formated everything and now i only have recovery to boot into with no options to install a firmware with odin since it fails.Tried with smart switch as well,nothing.I guess it has something to do with the fact that i coudn't copy anything on my internal storage.Any ideas?
Issue solved,used adb sideload to install a custom rom and that worked
