Galaxy S4 i9515 Stuck in Bootloop After Flashing ROM - Galaxy S 4 Q&A, Help & Troubleshooting

[Rooted][i9515] OS Problems?
I have a rooted Samsung Galaxy S4 i9515 and I tried to flash a mod in CWM. The main problem is that all my apps stopped working and the screen is black. I tried rebooting in recovery mode but is restarting and refuse to open in Recovery Mode. The only thing I can access is the Download mode, which is working fine (I hope).I did a Nandroid backup before flashing but now I can't access that neither. Anyone has an idea what happened and how to solve this?
Edit: I reflashed the stock firmware and now the phone works fine, I think the problem was a corrupted sistem file but now I lost the root access temporarily.

[Q] Trouble with TWRP. Please help

I am having issues with TWRP. I have my galaxy s4 rooted and the customer recovery installed. Whenever I create a back up it works flawlessly. But when I try to do a wipe/factory reset or a restore or an install of a different rom, the system starts then the recovery resets itself. I cannot figure out what the problem is.

[Q] Stuck in bootloop

So i tried to install iphone emojis on my galaxy s5 sm-g900f and i restarted my phone but it got stuck in a boot loop.
i tried to flash the original font in recovery mode but to no avail.
i want to know how i can get my pc to recognise my phone so i can access the root directory and replace the fallback_font.xml with the original to fix the problem
my phone is rooted on 4.4.2
Try flashing with a recovery, to pass the bootloop issue..
And I think, you can't access root directory by PC. I think so. Not sure.
Flash a stock ROM with Odin. And next time always make a nandroid backup in recovery before doing anything
I fixed mine by letting the battery die amd charging again.

[Q] Un-soft brick my s5

I was recently flashing a rom on my rooted Verizon S5 via Safestrap on one ROM slot. I flashed the rom then downloaded the 0A8 kernel. Upon bootup, the phone was stuck on a boot loop, but I can get into recovery and download mode. I have already tried to factory reset the phone via recovery and I have also tried to put on the stock kernel again. Both were unable to resolve the issue. I have a fulll nandroid backup so wiping anything would not be an issue, but is there any way to solve this problem?
Also, when the phone boots up, it stays on the S5 boot screen and you will hear the boot sound but it will remain at that screen for an infinite amount of time. Can anyone help?
Thanks!

Galaxy Note 4 stuck in bootloop after flashing Stock ROM

Note 4 bootlooping and Samsung logo screen.
Phone is a Note 4,rooted, N190w8(Qualcomm). Used CWM rom manager to boot into recovery mode to do a Nandroid backup to prepare for flashing a custom rom. That caused the first bootloop. I tried to fix it by flashing the stock firmware and now my phone makes it to the Samsung logo and stops. Wondering if anyone has a solution to this problem. At this point I just want to have a working phone aha. thanks.
Does it boot on Galaxy Note screen and restarts in a flash? Can you boot in recovery mode ot it reboots before it ?
Could be rom file damaged or not fully downloded. You can try download different country rom and flash with odin. I'm sure it will work.:good:
