HELP! Strange problem - myTouch 4G Q&A, Help & Troubleshooting

I have installed Cyanogenmod on my MT4G, it was working fine for few months, but now it is developing a strange problem with the display. The symptoms include:
The screen is pixelated when displaying text, and colors are distored (at first a reboot took care of the problem, but now the problem no longer goes away)
No display of the myTouch 4G splash screen
When boot into recovery, I can see the recovery menu VERY briefly, then the screen goes dark, completely black
When boot into bootloader, the screen is completely blank. Can not see anything.
I was thinking the problem may caused by Cyanogenmod, however, because now the screen is completely blank, I can not even restore to stock using the Power+Volume down method. I do know that it still entered bootloader mood since I can see the device using adb/fastboot command.
Any pointer as to what may have caused this or help getting me restored back to stock would be greatly appreciated.
Note, I have wipe the phone, I have tried Cyanogenmod 7.1, nightly build 252 and 7.2RC1, and the problem is still there. I was not able to flash a stock rom using rom manager.

Multi-colored Screen

Hi Guys
When I turn my phone on, after the Galaxy S first screen, the screen is multi-colored for about 1 second before going to the boot animation. Once the boot animation appears the screen is fine.
That's not a problem. What is a problem is booting into recovery, the top of the screen has a few blue lines. It still operates as if it is in recovery, as if I press the power button it reboots - but if I press down once, then power, it's not rebooting. So it looks like it's just the screen can't display what's being sent to it. So I can't do anything in Recovery like installing the auto-phone record, screen capture service or extended power menu. It will also be a problem if I come to install another ROM.
Does anyone know why? It started happening after I flashed a new ROM - I flashed the new ROM because the phone was constantly freezing when running certain apps (and needed the battery removed to restart the phone) - it's no longer freezing.
thanks
I'm not sure but,i think it because you don't have the good bootloader.For example,if you flash a rom from Froyo to gingerbread,you need to choose a rom with the gingerbread sbl(bootloader) include.
So to avoid this problem,just re-flash the entire rom with boot loader included.

thanks I'll try that

[Q] htc g2 tmobile no hard reboot

used gingerbreak on g2. Got superuser and everything was great. Now (don't know why) no splash screen, no recovery even holding down volume and power on boot, random screen blackout. tried to re-gingerbreak with no effect. tried hard reset with no effect. stuck in hell please help. phone is stock rom and has no modifications even has all bloat-ware.
p.s. initial problem upon booting screen black but have lights at bottom after stock boot sound hit power twice and phone is active like normal. now stuck like this after each boot and couldn't find anything about the problem after searching. I hope this hasn't been covered before. Any thoughts? I am at my wits end about to get out the light saber and take out my frustrations on the mutt

[Q] HTC HD2 Won't Boot - glitched boot logo too

Recently my HD2 has been acting up a little, it's running android (I've basically followed and installed everything on htchd2android.com/how-to/how-to-install-android-on-htc-hd2-android-4-0-4/), and yesterday would just show the green HTC logo for a second before turning off whenever I tried to boot it up.
I tried taking out the battery and sd card, put it back in to boot up, but this time the screen flashed yellow and white and went all glitchy for a few seconds, and ever since when I try to boot it it shows a glitched HTC logo and stays like that indefinitely.
(You can see what the screen looks like currently at i.imgur.com/42kYqkl.jpg)
I've tried reinstalling the custom rom, everything bar a factory reset (which will be my last resort), but really I just want to know what's caused or causing the problem.
Any advice appreciated!
Had the same problem yestrdy and i flash the rom again now its working fine.. but you wait for someone's solution i suggest if ur data is important

N4 Semi-Brick? Can I recover?

Hi,
I have a N4 that was new but the screen cracked on it and eventually the battery died as well (wouldent hold a charge). I got the battery and screen replaced but as soon as this happened I could not boot into any rom. I had twrp installed but everytime I tried to install a rom such as CM it would install but would stay stuck in the boot loader. I then used NRT to try and kick it out of bootloader and I tried several different stock firmwares, 5.01, 4.4.4, and 4.2. The only rom that was able to get past the boot animation was 4.2 it went to the welcome screen to choose a language but I could not select anything via touch screen. In that screen I could lower and raise the volume via the rockers and turn the screen on and off. I had twrp installed and the touchscreen worked fine in twrp. I also tried this: http://forum.xda-developers.com/nexus-4/general/tutorial-how-to-unbrick-n4-t2347060 and it also let me get into the developer firmware but of course it is encrypted so I could do nothing. The phone has not had contact with water etc. Do I have any other options? Can I get some type of diagnostic such as logcat or something?
Thanks!

Need help to unbrick my phone

Hi,
I have a Note 4 t-mobile that is "brick" right now. and I hope if anyone offer assistance.
It is running Android 6. Ever since the last upgrade the phone would freeze and reboot on its own. I fixed that problem by installing Wake Lock. After that it would still experience sluggish at time but the phone is still very much usable.
Lately, after watching a bit of streaming video the phone would slow down so much that a reboot is needed. But yesterday my last reboot turned my phone into a brick. After that reboot the phone rebooted itself to the download mode. So I took the battery out, waited for a few minutes and put the battery back in and started the phone. Instead of booting normally the phone displayed the message including "set warranty bit: recovery" and then followed by the flashing TWRP splash screen. By "flashing TWRP splash screen" I mean the TWRP splash screen ( with the TEAMWIN logo) would be shown on the screen for a second, then the screen black out for a couple of seconds, then the splash screen is back on for a second, and the screen black out for a couple of seconds, etc, and never successfully boot into TWRP recovery. I had left the flashing splash screen overnight and nothing changed. Connect the phone to my pc via usb and fastboot wouldn't recognize my phone when phone was flashing the TWRP splash screen. So I tried to flash TWRP again by starting my phone in download mode "volume down + power". When I connected my phone to my pc Odin recognized my phone. But when I tried to flash a custom recovery (TWRP or CWM) it seems the download started but never finished (on the phone I could see the progress bar started but never progress further).
Any suggestions would be greatly appreciated1
Additonal info
I just wanted to add that my phone is still running the stock ROM.
Problem solved
Problem solved. Once I used a different cable and the download process actually worked and I was able to flash stock ROM using Odin.
