[Q] Screen doesnt come on till Boot - G2 and Desire Z General

This is kind of a weird question to ask, but Im more concerned than in a pinch.
When I go to reboot my phone, the screen stays completely black till I hit the CM7 RC2 OS, then the buttons flash, and I can press the unlock button and the screen will turn on and I can see things. Before then, it all just stays black, even during boot.
To sum up, I don't see anything during boot, but I can feel the phone vibrate and come on. I *think* I can boot into Recovery and Bootloader, but the screen still doesn't come on during either of them. Its as though its not being recognized until the OS is hit.
Anyone else run into this? Thanks~

I don't know much about this stuff, but could it be that something happened with the splash screen that made it corrupted or something like that? You could try to flash a different splash screen using this method- http://forum.xda-developers.com/showthread.php?t=947077.

[Q] Boot up screen

I installed Euro firmware, on the second flash everything just stay'ed black, and I waited awhile till I decided to power off then power back on. First thing I saw was AT&T connect boot screen, then it went black but I can still hear Samsung's power up theme, also device has a Vertical Line running down the right side. I noticed that If I press power button twice Tab comes on, and everything looks great, so I rooted my device and installed Titanium Backup,Everything seems okay. So my question is how do I get rid of the AT&T Boot logo and to be able to see Samsung logo on boot?
\\\\\\\Exactly what happens on fresh boot/////
-fresh boot- AT&T Connected screen comes up, then screen goes black with the line on the right, then Samsung's power up theme song comes on buttons light up screen stays black line goes away, then screen still black, then to initialize the screen I press power button twice. Comes on and works fine.
****Would love to fix that part, I would be most greatfull for life! Willing to pass on info, to all who want more!****

Install euro firmware with bootloaders. JJ4 is good one since it's bootloader is not signed. Then you can install newer euro firmware over it.
However, so far there is no known way to go back to AT&T bootloaders. So you ca't fully restore to AT&T if needed.

Screen turning itself off when I slide it in

Hey guys, I jsu bought a used G1, since I needed a phone because I've started developing apps for android. Anyhow, since I don't have much money I had to buy a used one.
So this one has a (quite big) problem - when the screen is on the keyboard (normal position) the screen turns off. You can see the backlight, but nothing else. When the screen is slid out, it works perfectly fine.
Any idea what the problem may be?

It can be a problem with the ROM also can be a hardware problem.. Try another ROM first and report back.
I tried more than 3 roms, still does the same.
I also filmed how it turns itself off:

Forgive me for stating the obvious, but have you tried wiping?
Yup, more than once.
At this point, if it was my phone, I'd consider breaking out a screwdriver set and try to see if something came loose or is worn.
Well now it's not working at all.
Not even when the screen is slid out.
And I don't have the required screws to open it... Guess I'll have to buy them somewhere :/
EDIT:
This is weird.. I somehow managed to turn it on, but now it's stuck on a black screen with "Build: " at the bottom of it...
EDIT2:
And now when I rebooted it, only the backlight turns on...
EDIT3:
When I turn it on regularly, the T-Mobile G1 screen appears and then disappears. You can still see the backlight, but nothing else happens.
When I turn it on to recovery mode, the G1 screen appears, then disppaears and then you can see a black screen with "Build: " at the bottom.
EDIT4:
Apparently, when I start it regularly, it does boot into Android, but it's like stuck.. Seems like it's kinda bricked? No idea.
EDIT5:
Is it possible to reinstall the ROM without having access to the recovery menu?

Getting a set of screwdrivers/torx/etc is a good idea. I picked mine up on eBay awhile back. An investment every techy guy should make.
It also sounds like you may want to get acquainted with adb and particularly fastboot. You *should* be able to use fastboot to get a working recovery and then use the recovery to get a rom loaded. This: http://forum.xda-developers.com/showthread.php?t=532719 seems like a decent guide to get you going with what you need if it is in fact a software issue.
Since your experience keeps deteriorating, I'm beginning to wonder if a chip inside is going bad - especially with the odd things like "Build: " showing up. (Let's hope this is not the case!) Nevertheless, I think I'd start with fastboot and go from there. Good luck.
Thanks a lot, ill try it as soon as I get home.

EDIT1:
What the hell? All I did was delete the recovery (didn't even install a new one, kept on saying it's missing the file, even though I did move it using adb push) and now suddenly Android works normally.
EDIT2:
Well now it's stuck again, just like before deleting the recovery...
I'll try to reflash the recovery and then see what happens.

[Q] Black Screen of (permanent) death?

Running the rom in my sig. Downloaded and installed Wikitude world browser from the marketplace, and now I've got the black screen of death. It won't go away even after a reboot. What can I do? I haven't backed up my android in a LONG time and I'm not prepared to lose everything!! Any way I could recover it?
could try using 'android commander' to uninstall the app via the pc?
Hello,
I have a similar problem.
In my case, its truly "permanent".
I haven't installed nothing special, nor did I do anything special that could've triggered this screen of death. I just had the app LiveRadio on for less than 1 hour.
I turned off the screen with the end button, and when I pushed it again, the back lights went on, but no image at all, just black!
I googled this poblem, and tried some solutions, like turning off/on the device, taking out the battery and so on, nothing worked!
The most bizarre thing though, is that the screen is permanently black! It's always black, be it in bootloader mode, spl, mgldr, or something else, no image is displayed.
I even tried to hardreset my android soft (I managed to do it somehow), but this didn't chase away the black screen.
The screen responds though. I managed to use androidscreencast to control the device via my PC, everything works normally, touching the screen triggers the desired commands, it's just pitch black...
Do you think my screen is broken in some way? Or maybe there is a problem inside the phone, a linking issue.
Does anyone have an idea? Thank you in advance.
what you could do, as you are using your pc for doing tasks on your phone, is perform taks 29.. then flash the windows mobile rom (trough sd and rename .nbh file to LEOIMG.nbh) this way your HSPL is deleted aswel.. and then what i would do, is send it back to repair.. because i think your screen has a problem.
I don't know if you are able to do all those steps as if you have to pull down the volum (or pull up?) to proceed the windows installation when going first into the 3colored screen.

[Q] MIUI-1.6.10-demonSPEED-v1.1, WILL NOT BOOT

So as the title says i currently have MIUI 1.6.10 demonSPEED v1.1 ROM and it is not booting, just completely unresponsive to everything i could think of. Im just throwing this out there to see if this has happened to anyone before or if there is a way of fixing this issue. I don't believe it has anything to do with thederekjay's rom just some unfortunate event. Anyway i fear it is possibly bricked and that i am gonna have to shell out the $150 to get a new mt4g from the insurance. Details follow...
So have had this rom for about a week now and has been working great. However this morning i was on the browser reading the news and it became unresponsive. After i let its display turn off (i just left it alone) i used the track pad to wake it. It was slow but it did show me the lock screen. When i attempted to unlock with a swipe down i felt the vibrations but the slide lock didn't budge. I then tapped the power button to turn the display off and tapped the power button once again to turn it on but nothing, just stayed black. I tried a soft reset by removing the battery, placing it back in, and powering back up. When i did so the t-mobile mytouch 4g boot image w/ the white background came on then went to an android image (lighting up a through d, looping) but then it just remained at the android image for five minutes! So i tried a soft reset again but the same thing would happen, act like it was gonna boot up completely but then gets stuck at the android image. So then i tried removing the battery and booting into recovery (via power, vol down, trackpad) that time the t-mobile mytouch 4g image would appear but after that the screen went black and after that every attempt with either the soft reset or boot into recovery wouldn't do anything at all, just a black screen as if the battery wasn't in at all. Its been like that all day and i can't figure it out so if anyone knows some info i would greatly appreciate it thanx

Damaged screen causes reboot, eventually gets stuck in boot loop

Hello, so I have a J7 2017 (SM-J730GM/DS) 32 GB Unlocked Dual SIM which has served me well for a while. I ended up dropping the phone at some point in a sliver of time without a case and the screen cracked. After replacing the screen I noticed if the screen was pressed in a certain area it would go crazy and reboot the phone (crazy as in the pixels would do weird things like dimming, going grainy, like the display shorted in some area, then the phone would reboot itself), probably some error on my installation of the screen and the ribbon cables (I can see an area where it looks creased, it never sat flush with the body of the phone as the OEM screen did). I was able to just be careful and not trigger the reboot for some good time until it happened again and the phone would continuously reboot, allowing me to only get back to the OS through the boot menu, selecting "reboot now". That worked for a while until it would never boot into the OS, just looping at the screen where it says the phone name, where it would vibrate, go black, and go back to the phone name screen. I gave up trying to fix it, as I had a backup phone, and just now had some ideas. I figure the OS is corrupted in some way, I am no master in knowing the details on how phone boots up and such, so I did some research and successfully flashed the most recent ROM onto the phone using Odin 3.14. It still doesn't stop the looping, unfortunately.
Any ideas? I hear people talking about using TWRP or something to do things boot related, but I don't want to possibly mess anything up further nor do I know what they were talking about.
Thanks,
Stella
