[Q] Screen Issues Lead To Bricked Device

I was trying out using a keyboard with a cheap USB OTG cable, and all was good. Then all of the sudden the screen went buggy, where ever other line of pixels was shifted to the left or the right, almost like some sort of corrupted video file. It started to reboot itself, and it got to the black screen with the Google logo and then the screen fuzzed in the same way as before. It then starts to reboot and does the same thing over and over again. I find that I can get to the recovery screen with the scroll arrows. From there, if I tell it to reboot into recovery it goes back into the same Google logo bootloop. I then went back to the original recovery screen and I decide to try out adb to see if it works. Sure enough it does, and I unwisely start flashing a stock 4.2 bootloader image. However, while it is flashing the screen does the same fuzz thing and and stays fuzzed. Then it doesn't respond to anything. I take out the battery, and try to restart and with will not turn on at all, no vibration, no light from the screen, nothing. I tried a unbricking methods from there, and nothing can make it come back alive. Any ideas?

[Q] HTC Desire HD boots but black screen afterwards

So I have a rooted HTC desire HD with Jellytime on it. All was working great till recently when it would shut down by itself. Today after I wanted to test a new boot screen from Rom toolkit I restarted it and while the boot screen worked great after it finished I see a black screen (backlit so I know its on). I tried going to the bootloader but after I try to go to wipe cache for example it restarts by itself and it gets stuck after the boot screen... Any ideas?

ok an update seems that if I go to the recovery via down button and power it lets me do actions. All this time I went to recovery mode when phone was shut down and plugged into a power source. I did a wipe cache and now it says android is upgrading and now it finished saying starting apps. Hope it didnt get stuck there because it keeps doin the cycle animation but doesn't do anything else.. I ll leave it be for a bit like this... :/ Had to restart it by removing the battery after 20 minutes... same problem as before still...

another update... just before it goes to a black screen when the boot screen finishes an orange light appears just briefly (where the green light appears when it charges)

Wipe everything (system data cache) and install a stock-ish ROM. What happens?

I flashed the rom again and wiped data and all seem to be ok now. I ll update this because I saw many people have similar problems... thanks in advance for any help!

Have the same problem.
I bought this with the problem that it keeps rebooting all the time.
I unlock the bootloader with htcdev,root with Easy Ace Tool,flashed the new cyanogenmod 11,
but did the same .
At least 3-4 rebooting before open normally.
I said that it must be ROM issue and flashed the KK-LegacyCarbon-4.4.
Did the things should be...flash the ROM and then the boo.img separately.
Now i have black screen and the only screen i am able to get is bootloader and the recovery 4EXT.
I reflased cyanogenmod back but nothing happened,any thoughts???

[Q] I've made a huge mistake, flashed Verizon S3 kernel on ATT, phone will not boot

I tried flashing the Zeus kernel using CWM, but I failed to realize the kernel was for the Verizon S3. When I restarted after flashing, it displayed the Samsung logo for a split second and then went to a black screen. The screen was on, but it only showed black. At this point I passed out, and when I woke up it was still on the black screen. I pulled the battery and tried to restart, and got the same black screen. Then I tried every way I know of (except using a jig) to get into download mode to no avail. Now when I turn it on, it vibrates once, flashes the logo, and then the screen shuts off and is useless. I think there's a solid chance I've ruined it this time, but if anybody has any suggestions they would be greatly appreciated. Thanks!

Put the phone in dl mode. It's possible the screen will be black and you can't actually see it's in dl mode. Plug into your computer. Odin flash a stock Rom.
The fact that it's doing something means it is not completely ruined. It just may be harder to restore to working order.

Sleep/Wake problems [SOLVED]

So i was using Darthstalker v3 and arter97 kernel 9.3 with no issues.
Suddenly one day, i noticed screen flicker when waking the device, followed by hesitation. So my first step was to wipe the dalvik/cache. That apparently did not help.
I then lost my bootup logos, as well as shut down, along with the screen pretty much refusing to come on.
I used smart switch to emergency recover the stock firmware. Nothing. Then i Odined a stock untouched rom. No change. Once i actually got the phone to render the screen in recovery, so i wiped everything three times, and and flashed darthstalker v6. I also rooted the phone again just before that. I
So when the phone is powered off, the battery icon is present, and the screen wakes to that no problem. Since i set the device to never timeout while charging,
when i plug it in, the screen comes on, but as soon as i try to touch it, poof, the rendering of the screen goes. But, while this occurs, i can hear the icons being pressed,
etc. Completely stumped as to what to do. Can someone help?
[SOLVED]
strangely enough, I found a solution in a most peculiar way.
I managed to finally get into the phone by charging to 100 percent. Then, I downloaded flashify, and attempted to flash tekxodus rom, as well as selecting dalvik and cache wipe.
The flash did not work. the phone just rebooted. Then, I downloaded rom manager premium, and then rom manager attempted its prerequisite attempt to detect my recovery. (up until that point, I had twrp installed).
The detection lingered, so I pressed the back key and selected reboot into recovery. Surprisingly enough, I was back in Stock recovery.
So apparently the solution to the anomaly I encountered in the OP, is to either follow the simple steps above, or, to flash stock recovery in Odin. If that is at all possible for the user. I can confirm the above worked for me as I tried everything for the last week and this was the only method that worked.
The shutdown/startup logos are back, with no screen flicker or hesitation on sleep/wake.

yeah i just suddenly started having this problem. my phone would reboot itself and then it would be updating apps as if i just flashed xposed or something, my phone would have issues with wifi, flickering lockscreen, and if you rub the screen while its off which wouldl show you information stream doesnt work either. Decided to dump the rom. Am going with the TEKXodus N5 with arter kernel

It's just like I told you. When I read that you had experienced the same precursors that I came across with the rom, I had a hunch you would be soon after posting the exact issues that I eventually ran into.
So when you download Tekxodus and flash, please keep me informed as to if it resolves the issue. As you are aware, stock firmware has not resolved the problem for me, but then again devices vary.

So enjoy the fix if you ever run into the above issue.

Im fine with stock, but I miss the fun of trying new roms.

Overheating, freezes, and screen artifacts

Hello,
Ive had this device for now 3 months and never once had a problem. I did however stay on stock for quite awhile just rooted. Recently Ive been testing out different roms and ran through quite a few until I heard about the all mighty CM gem by Sultan. So I figured I would give it a shot. Went ahead and downloaded that along with gapps like any other rom. Booted into TWRP and wiped both the system and cache/dalvik. Then went ahead and attempted to install the rom. Unfortunately midway through it froze and my screen artifacted. I figured I would give it a few seconds and the screen turned black with the notification light turned on. I then tried to reset it with a volume+power combo and nothing happened. After about 5 mins of letting it rest it turned back on.
I went ahead and tried this process again thinking it was just a fluke but nope happened again. So I figured it was a corrupt zip file and I would just go back to the stock image I flashed before which was working perfectly fine. Again froze and gave me artifacts. Hoping to find an answer I downloaded the latest TWRP image and flashed the roms again. Same outcome. I even went out of my way to flash the stock recovery, fully reset all my data through there and then reflash TWRP and sideload Sultan's CM. Which I for once actually got into the ROM however now whenever I get into the ROM my phone overheats instantly and I get the nasty artifacts back along with a reset of the phone. Well kind of the screen goes black and I have to wait until it cools off to turn it back on or else it wont turn on.
Anyone have this issue? Anyone know how to solve this? This is my only phone and I go off to college next monday. Thanks in advanced.
UPDATE: I now cannot get the phone to turn on. No haptic feedback, no LED notification light, no recognition in windows. Literally a paperweight at this point.

The same here, flashed CM and Gapps...
Phone hangs on boot, rebooted the phone and now it won't go on..
