Stuck on boot logo after flashing (the wrong thing...) - Samsung Galaxy J6+ Questions & Answers

Hello!
Today I started to install TWRP and flash RR. After a few problems with Odin, I successfully installed TWRP 3.2.3 on my phone.
I have tried many times to install RR because each tutorial said different ways and I still do not have much knowledge about that.
3 hours ago I tried to install RR for the x time and tried to install from zip folder RR the boot.img file. But I did not select it as boot but as recovery.... After that I rebooted. And since then the phone gets stuck at the boot logo.
I cant't enter the download or recover mode. Can only restart it by holding down all buttons or the power and volume down.
I know that it was not the best idea. My phone is also 3 years old now. And that's why I'm thinking about buying a new one.
My new one would otherwise be the Samsung Galaxy A21s.

[Q] F240L Stuck in recovery, won't boot to system or anywhere except to the recovery.

I was on stock F240L20D, 4.4.2 Kitkat, rooted, PhilZ Touch 6 installed. I've tried some ROMs before but reverted back to this one. So, basically, I've been to the recovery several times, but only used the ADB method to access it, and I've made several backups too.
However, one thing that happened today has frustrated me completely. Long story short, I thought about making a backup again, although this time, I used the power keys to get to the recovery instead of the ADB method, backup completes successfully, nothing wrong just yet, but just as I tap on 'Reboot System Now', it boots back in to recovery.
I've tried everything, tried using all the ADB commands, even going through all the options in the recovery, but it always seems to boot back in to the recovery. Really can't figure out what's happening. Any help would be extremely appreciated.
UPDATE: So I've flashed a KDZ, the Lollipop one using the LG Flash Tool. It's taking a bit too long to start, currently stuck at the U+ Lte logo. I hope it gets fixed.
UPDATE 2: It says Android is upgrading, YES YES!!!!! This is so exciting, but I'm still not convinced.
With most of cwm version after 6.4.7, any time you use power + volume up to access the recovery, you will get the boot loop. Go here and down load the zip file from the first post. Flash the zip and you should be go to go.

Rooted, TWRP installed. Custom ROMS won't boot

As the title says. As soon as I try to install a custom ROM phone doesn't even reach the LG Logo. Just boots to a log screen, with the last line mentioning fastboot mode (however its not in download mode).
Tried going back to stock and trying to reroot and installing twrp agiain, but no luck. Think there may be a problem with my phone.
Last time I had a custom ROM installed a couple of days, it kept crashing giving me a green screen log.
Any ideas?

Robin on Nougat Won't Boot After Flashing TWRP

I just upgraded my rooted and bootloader unlocked Robin to Nougat last night by installing the official upgrade files from the Razer Community forum. I've tried installing TWRP several times through fastboot, and each time I can get the phone into recovery, but the phone will never boot into the system. It hangs on the black "Nextbit by Robin" screen, and never goes past it. If I turn off the phone by holding down the power and volume down buttons, and then turn it back on, it still won't get past that screen. I can always get into TWRP, though, but no matter what I do, the phone won't boot. I've been using TWRP 3.1.0. Is there a different version that's required for Nougat?

My guess is you messed up the boot.img, or worse you corrupted some partition. If it's the boot.img, go get the latest factory image, unzip it, and move the file 'boot.Img' onto where your adb and fastboot files are located. Then go into fastboot on your Robin, and run this command on your PC:
Fastboot flash boot boot.img
If you corrupted something, you basically need to go into fastboot and use the flash-all.bat in the already unzipped Robin_nougat_88 folder to bring your phone back bone stock.
Hope that helped
Had this issue with my phone at first, but eventually just fixed it anyway by flashing the decrypted boot.img.
I ended up fixing it the same way you did. No matter how many times I took it back to stock by flashing the files in the Robin_nougat_88 folder and then flashing TWRP, no matter which version of TWRP I used, it would never boot. I finally flashed TWRP, then booted back into recovery, wiped the phone, loaded and flashed the decrypted boot image and SuperSU, and then the phone booted fine. I should have just done that in the first place since it was always my intention to unencrpyt it and rooted it again, anyway.

Samsung S4 mini GT-I9192 Help with Cyanogen Mod 14 Booting Loop

So 3 days ago I updated my stock kitkat rom to CM 13, but I realised that marshmallow cant write on my sd so i tried a couple of fixes flashed on my device, namely the latest sd fix (2.9b) and so far so good except it didnt solved my problem, so I tried flashing the 1.9b version of the fix through recovery mode, after I finished flashing the TWRP apk asked me if I wanted to install the su apk, I didnt, so I clicked the reboot option instead except it didnt rebooted my phone so I held the power button until it turned off, next thing i know I tried turning my phone on and It gets stuck on the blue mascot booting animation for as long as I let it sit.
I already tried flashing a new CM (14) and factory resetting all to no avail, basically Im blind as to what i must do now. ANY help is welcome.

@thorium231 I love you man, the problem was with CM after all.

Z2 Plus Boot issues

I was on AEX and tried a new roms (Pixys, Evolution, Pixel Experience etc) and none of them booted the android.
Tried to restore AEX and even that is not booting. Phone keeps rebooting in loop without booting to any os including the restored backup.
Evolution and pixel after a clean installation says "no os".
Phone stays in start mode and does not move beyond this point.
Phone boots to twrp recovery.
Any idea what is wrong? Have corrupted the phone that it can't be used?
Is there a way out?
Quick solution would be highly appreciated.
Thanks
Anyone has a solution/suggestion for this?Deperate now since there is no alternate phone.
Thanks again
The phone boots recovery and adb commands work whereas fastboot commands don't work. I am able to flash vendor2factory and rom successfully with no error but the phone still not boot android but vibrates and goes back start screen and if i don't press any keys it restarts again after showing the ZUK logo.
I hope i have been able to explain the situation. I am still not able to boot the android despite trying more than one rom.
Anyone has any clues? Thanks

I am having the same problem. I was in pixel experience and i flashed latest pixel experiences august security patch, it showed no os but it booted. But there were several bugs in the rom, i thought it was roms problem and then i tried to flash evolution, it again showed no os after flashing and then i got stuck at evolution x boot logo. So, i tried to qfil zui but to no avail, the flashing process won't even start the qpst tool just freezes after pressing the download button. Then in the twrp i noticed that battery percentage is different at different times sometimes it shows correct value but somes it won't so i thought that the problem might be from twrp and then i flashed new twrp but again same problem. Then i flashed arrow os 10.0 without gapps, it booted successfully then i flashed gapps. After sometime i tried to flash evolution x but got stuck at boot logo again. Finally i flashed arrows os again it booted successfully (i flashed rom and gapps separetly)
So, FINALLY THE TEMPORARY SOLUTION IS TO FLASH ARROW OS IT WILL BOOT SUCCESSFULLY BUT THEN AGAIN OTHER ROMS WON'T BOOT. IF I FIND ANY SOLUTION I WILL POST HERE

When you qfil, the recovery will be lost i think. But since you cannot enable usb debugging i think you wont be able to flash twrp.

I think the problem is our phone is not able to boot big rom i.e. roms of size close to 1gb or more than 1gb since arrow os without gapps is only 600mb my phone is able to boot. If you are able to find the solution or get your phone repaired at any cell repair centre please let me know
bro is your phone working now
