Hi, after i replaced the screen, screen lights up and works normally but phone wont even boot to recovery mode. It just keeps restarting. When i put old screen back, screen is not working, but i know, that it booted because buttons light up. I dont really know what to do now. Any suggestions ? Thank you.
take the back frame off of the device, short out the two power button leads, to boot it without the button. see if it boots.
Maybe it’s too late to help you, but LCD for G901F is very specific. Here is the one I ordered, and my S5 is now OK. https://www.ebay.fr/itm/183173477341 Have a nice day. Alain.
Could also be a baterry issue. Like in this video : https://www.youtube.com/watch?v=UGrVc4If…
I have just the same problem with my S5, download mode without any problem but I’m unable to reinstall OS because computer won’t connect with the phone, I go this message when trying to restore with Heimdall: Initialising connection… Detecting device… ERROR: Failed to detect compatible download-mode device.
