Hey everyone!
I have a Samsung Galaxy S7 flat (G930F).
I constantly run into boot loop since I restarted my phone with no OS.
My story:
I downgraded my phone to the stock Oreo firmware using Odin. Everything went fine.
After that, I also flashed the TWRP package with Odin. I have used this package several times before and it's okay.
Then, I boot into TWRP and did the following:
I wiped Dalvik, System, Data, Internal, Cache.
I went ahead to install LightRom. Unfortunately it has failed to install.
Ever since this happened my phone is in bootloop. I can't boot into download mode or recovery.
I have tried:
Volume DOWN + Home + Power for Download mode -> No luck
Volume UP + Home + Power for Recovery mode -> No luck
Please help me if you have any idea how to fix this!
Try use adb tools to boot in recovery via laptop/pc.

I'm in a serious trouble please please help
So I had cm 11 on my s3 first then I decided to go back to stock and installed 4.3 official s3 firmware using Odin.
Then my phone restarted and was stuck at the Samsung logo
I checked for a solution online and found that I should wipe cache and data and here is where the problem is
When I hold down volume up or down with home and power button it only opens download mode and I cannot wipe cache and am terribly stuck....
PLEASE HELP! Thanks in advance

The 3 button combination in order to start the phone in Recovery Mode (where wipe options are) should be volume UP + home + power.
Avoid the volume DOWN combination because that is for Download Mode.
Try start in Recovery Mode several times because sometimes the proper combination timing is not detected.
If really the phone can't start in Recovery Mode, you should flash the official firmware again via Odin, following the procedure with caution. An important, sometimes overrated action related to flashing via PC is that any antivirus (firewall mainly) must be turned off before the flashing procedure, in order to avoid (invisible) conflicts when transfering data through USB ports.

First of all the boot up loop is caused because you have not wiped the cache and dalvik cache (may be).
Since the recovery is not booting means, there is some error with flashing.
What you can do right now is to flash the Original Stock Rom using Odin, the original stock OS itself contains the recovery partition.
Okay so I'm not new to rooting, flashing custom roms, or using custom recoveries, but this one has stumped me.
After reading and researching several poorly written/translated guides I set out to flash the Miui6_5.3.20_r827_b3wok custom rom on my Oppo Find 5 Mini. I copied the CWM for the R827 into the sd card, using Mobile Uncle MTK tools to install it. I successfully rebooted into CWM, selected the factory reset option (wiping data and cache) and then format /system and wiped the dalvik cache. I then installed the zip of the custom rom, with no errors. However, the custom rom needed a patch, specifically the "VPN-Fix by Louise - AICP v10 - R827" which acc. to the instructions were supposed to be patches BEFORE gapps.
Now the problem is that at the end of flashing that patch, it automatically reboots the phone, so I held the power button while the Oppo logo was there and booted into CWM again. I then flashed gapps, and rebooted the device.
However, I am no longer able to get into CWM, nor does the Oppo logo move/progress. Pressing Volume Down + Power to get into recovery mode turns on the phone with the text =>Recovery Mode in the bottom left, but instead of going into CWM it now just turns off the screen, vibrates, and proceeds to boot as if I never attempted to go into recovery mode in the first place.
Is this phone well and truly bricked? Fastboot mode (Volume Up + Power) just vibrates the phone and turns it off, so theres no way I can do a adb reboot or sideload. I can however copy files to and fro the microSD card via a separate card reader, if it helps.
Thanks for helping , and sorry for the long read...This really is my last hope. :crying:
Update: Okay so I went to the Oppo store and after about 40 minutes they somehow both fixed it and updated to the ColorOS with Kitkat.
OP resolved.

Hi there, having just the old casual phone crisis. I was running cyanogenmod 12.1 for awhile and decided to finally upgrade to a nougat 7.1 build.
I tried using this one https://forum.xda-developers.com/google-nexus-5/development/rom-dark-rom-t3492150 using adb sideload as I had tried a earlier one and the gapps messed up so I wasn't able to put twrp back on the phone. The rom said it had installed successfully but I wasn't able to sideload gapps, I kept getting an error status 255. I went ahead and just tried to load the rom without gapps and see if I could install it slowly through APKs. I managed to get past the initial android load and the services started up, and it got in an endless crash loop because the phone service wouldn't start. So I went to try and flash another rom and was going to delete the cache. When I went to delete the cache the phone hung for about an hour so I tried to just reset it into recovery mode again.
Now when I hold the power button and volume down key to into fastboot mode I can. I have access to the initial screen with the four options, but when I try to start recovery mode or start the phone my screen goes black, and it'll flash the dead android symbol with the error saying unable to mount cache, it only flashes it for like half a second then goes black and repeats every 10-15 seconds.
I tried holding power down, doing volume up, and letting go to do a hard factory reset but it does nothing. I also can't seem to access the adb sideloading anymore, I'm very scared that it's hard bricked, is there anything I can do at all to fix this.
Flash a new version of the recovery via fastboot. Then do a full wipe. After that install the ROM only! Reboot recovery (not system but recovery) then reflash the ROM (no wipe) and add everything else. Hope this helps you out.
The phone may not boot the ROM without wiping data if installing a 7.1 ROM over a 5.1.1 ROM.
I've been using lineage OS rooted and TWRP installed, my phone was slowing down, so i boot into recovery and cleared all data and copied ROM and gapp files and flashed them, then it rebooted but it went again to recovery only, ever since, stuck in TWRP recovery and even if i tried to go to fastboot via pressing vol up and power button its going into TWRP, Anyone knows how to fix this
Long story short, I tried to install TWRP with odin and my phone keeps restarting after I did the reboot from the recovery.
This is roughly what I did:
Installed the adb stuff and android studio(because I don't know if the adb stuff was installed correctly)
Do the volume button stuff for download mode
Connect cable
Open odin
Add the latest twrp file in the AP space and start
The phone booted up regularly ... I can't remember which thread it was but it said to remove battery then boot to recovery so I did it.
The instruction I followed said to advance wipe something but I accidentally swiped to factory reset then it booted back to recovery I think then I went back to wipe what I missed earlier then I tapped reboot and system and it keeps restarting all the time.
I can still enter the twrp recovery mode and the downloading mode.
I think it's a boot loop and I read threads where the simple instruction doesn't work and I haven't tried the command stuff.
Hope someone can help me.
