Why my phone only shows black screen?

[AC Question]

Hi I have Samsung galaxy s5 exynos. I tried to change bootlogo to s7 style so I downloaded it and flashed it with twrp and it worked. I unziped the bootlogo file and added image from gallery and deleted logo it was there. I zipped it and again flashed it with twrp. Now my phone only shows black screen but I can go to download mode. Please help me.

If you followed best practice and made a nandroid backup prior to altering your /system files, you can use that to restore your phone with just one press of the button.

Otherwise, you can download the stock Samsung firmware for your model of phone, CSC and Product codes and flas it via Odin by following the instructions and video contained in the links of #1.11 of 42 Galaxy S5 models - Dummies Guide. This will, of course, unroot you and return your firmware to stock.

Can you link me to the firmware that you attempted to flash to your phone.

That is a very, very, old Android 4.4.2 firmware for the non 4G, octa core model, G900H, for Nepal. Try flashing the latest firmware, Android 6.0.1 for Nepal...

I downloaded it and tried to unzip it but after 33% it said file is corrupt and it stopped.

That is from the reputable SamMobile site. Try again.

I downloaded it again and flashed it but didn't work.
