[Q] GT-i9505 works but screen is black, no splash

Hi people. I have been running a rooted phone for a while and decided to go back to unrooted recently. I decided I would like to use the barclays app and apply the new updates that samsung rolled out recently. However when I flashed the stock firmware I found that the screen no longer worked. The phone seemed to boot up and play the samsung startup jingle but no splash logo. just a black screen. To test I decided to call it and the call came through ok and answered with the home button, speech all functional???!! Just no screen ... completely black??? Would this likely be a fault with the firmware or is it just uncanny timing with a faulty screen??? confused and wondered if anyone else has come across this before I go but a new screen. I downloaded the firmware from hotfile "I9505XXUDMH8_I9505OXXDMHA_I9505XXUDMH8_HOME"
thanks in advance

i would say to stay away from new firmwares at this time....you are stuck in the locked bootloader.
can you boot in recovery or odin modes and see the screen?
wipe data and cache and reflash the MH8 then do the wipe. see if that works
can not determine if it is a HW or SW issue.
if you want to use app that doesnt require root like Barcley and you are rooted, you can hide the root with some available app.

It seems I am able to get the device into download mode, although nothing comes on the screen. I just have to do the procedure blind. No matter what I do nothing comes up. It also seems I can only get the phone to read the internal memory through USB once a flash procedure has completed. It seems to force a boot up but when I try to restart manually it does nothing but vibrate and only seems to be able to put into download mode while blind. I find it very unusual that the screen should suddenly stop working the moment I try and flash the standard firmware. Getting worried now. nothing seems to work

Can anyone help here??? I have tried flashing several times. Just vibrates and does nothing. I can get it into download mode but I don't get any warning screen up. I just go through the button combo's blind and it manages to get into communication with a odin com port. I have tried doing a PIT download. What I was then finding is that the phone can bring up a recovery screen with option to reset, I reset but the phone will just be a black screen and play the samsung start jingle without the splash screen. It then seems to boot and receive notifications with a totally black screen. completely unresponsive.

If you can't see a splash screen or even recovery and download mode screens, then I'd say its a hw issue and no ROM is going to fix it, because those mentioned things are not even tied to the ROM.
Your screen has broken some how, it could be as simple as a flexi connector falling out or as bad as your screen being totally gone.
Sent from my GT-I9505 using xda app-developers app

It doesn't look like hardware problem
i am facing exactly similar situation with a 9505, i tested LCD with another of my 9505, and LCD is ok
is just happened after an Odin flash of stock firmware.

[Q] Calibrating touch screen.

I recently bricked my phone and flashed my firmware to fix it. I'm now in the lg welcome setup page where it asks your language . I can't press next or any button. It's like the screen is not collaborating . Tap on doesn't work or tapping out. It's an LG G2 D802-20C model and that's what KDZ i used. I flashed with LG flash tool 2014 with type "CDMA" since there is no GSM and CDMA was recommended. . Any suggestions?

[Q] Brick:"Unfortunately, the process android.process.acore has stopped"

LG G2 32GB D802
After bought I upgrade firmware from V20B to V20F using LG Flash Tool 2014. Ater flash new firmware the phone don't respond for touch. When I tried change laungage and touch example english(us) hi select other language, when touch any one of 3 buttons(arrow back, home, 3 lines) hi display: "Unfortunately, the process android.process.acore has stopped" and screen is frozen-no access to any phone settings. Phone is completly crazy: when I touch "back button" the phone select 2 diffrent buttons.
Option Recovery Mode(power button&volume down) are not available. The download option are available-I tried lot of times,again,again flash the firmware(ROM) but with negative result. Also I flash to stock ROM with negative result.
No access to any phone settings.
Any idea for resolve it?

Are they working when you restore KK backup (presumably you have one)? Before doing that, test your sensors by downloading any app from Playstore that can do that.
You can also try restoring just sensors you backed up in twrp (uncheck the rest of the stuff)
Try updating touch firmware to get your knockon back
Open dialer menu and type;
5689#*980# (Sprint)
3845#*801# (T-Mobile)
3845#*803# (AT&T Canada)
3845#*802# (International)
3845#*800# (At&T)
3845#*980# (Verizon)
And when hidden menu is showed up, go to "Settings"
and go to "Update Touch Firmware".
The touchscreen won't work until after 5 seconds, Wait for it and if touchscreen gets working, exit the menu.
Lock the phone and try knocking on the screen, It should be working

[Q] Lg G2 -D802 "knock on" is not working

My LG d802 phones touch screen has broken. It has been replaced with all new screen. In the same time, I get 5.0.2 v30b update. Now knock on(double tap screen on) is not working. But screen off working well. I updated touch firmware at the hidden menu , I flashed same Rom 5.0.2 v30b and I formated with hard reset. Still not working. Is that a software problem or hardware problem. Should I make root or flash another roms . maybe new screen doesn't support knock on?

I think its because of proximity sensor.

Hello,
I've used this for my LG G2 802
Go on phone call, type 3845#*XXX# XXX is your model, 802, 801, 805.....
After in the hidden menu, go in Settings, Update Touch firmware, wait 5sec because your touchscreen is inactive, lock the phone and the knock on will work.

I did it already . but it didn't fixed

I am having the same issue. I Replaced the screen (actually this is the second time I replaced it. When I replaced it the first time I did not have the problem) and now knock on does not work any more, but knock off does.
I updated the touch firmware and checked if the proximity sensor works fine (in the hidden menu). I also re-installed dorimanx 10.7 and set it to default, but nothing helped. Anyone has an idea what to try next?
