Hey guys,
I've done some searching on this issue, yet I can't find much besides battery problems, or people who have contacted T Mobile and got warranty replacements. I've had some issues with my G1. Over the past month or two, my G1 has been rebooting repetitively, and this week it's gotten BAD. I would open a SMS, and then BAM. Start dialer, and then BAM. Reboot. Hell, even in the middle of a reboot it would reboot. Cool huh?
Anyways I called T-mobile customer support and they said I'm out of warranty. Great. Well, it still turns on, and it still operates when it's happy, so maybe I can work with this for a little bit... I did some searching, and some people attributed it to a software glitch in the gyroscope... Most people called T-mobile and got a warranty replacement. I'm over the one-year
I'm not about to say this is because I had CyanogenMod on it, because I would wipe, and put it back to an older version and it would still reboot... even in the SPL, it would reboot. But regardless, I decided to follow this how-to to unroot my G1: http://forum.xda-developers.com/showthread.php?t=491350
After step 6 (6. Push Alt+S on your G1 to flash it with update.zip), it came up with an error about the splash... "Cant store hboot image."
Well anyways, before I could do anything about it, guess what happened?
Yeah, it rebooted.
It came up with the unboxing logo at first, I didn't know what to do. I had forgotten what this meant, so I heled the power button down ( I realize this may have been the misteak I made, however there was nothing visual indicating anything was being done).
It shut down, the screen went blank, the charge LED remained on....
I pressed power.... Nothing.
I unplugged the phone, took out the battery.... put the battery back in... Nothing. The screen stayed black. Now my phone will not power up, and there is no LED charging indicator.
Anyways, I'm lost. This is my second G1. I'm slightly pissed and I feel bad for the T-Mobile rep on the other end of the call I just had, but, really, I can't spend $1200 a year on a slow phone.
Do any of you guys have any suggestions?
Home+power does nothing.
Camera+power does nothing.
Putting in the cable lights up no LEDs...
It is literally a brick. An unresponsive brick.
Well, I ended up taking the mainboard out of my old phone and putting it in this G1.... Everything should be back to normal however I'm still looking for responses as to what might be happening.
Ok, I have been waiting for this phone for a while now (Sero plan, had to wait to Oct 1st)
Finally get it and it is acting up, not a good first impression.
Phone seems to "freeze". The screen just becomes unresponsive. Nothing is reflected as being done but I think the phone is still operating because when I took out the battery and restarted the phone, my txt draft was different from when the screen locked up (I was randomly pressing buttons on the keyboard after the screen locked)
The screen does not black out, it just freezes randomly. I can't press any buttons to do anything, I can only power off the screen and power it back on in which case it comes back to the frozen screen. My only option is to then take out the battery. Anyone have this occur to them? I don't like the idea of having to go to a store for a replacement 2 days after I received the phone..

Sorry I don't have a solution to your problem, but...
I'd do a factory reset before you take it back, back everything up, do the reset, and then restore it. A factory reset can work wonders for some odd problems.
http://forum.xda-developers.com/showthread.php?p=8448259#post8448259
Easiest way to restore is to use Clockwork Recovery on a rooted phone. 1 option to back everything up, wipe all the caches in Clockwork, factory reset the phone, restore the backup in Clockwork. Shouldn't take more than 15 mins. See the developers forum on instructions on how to root and install Clockwork.
I agree your first step should be a backup/reset. If that doesn't fix the problem then swap it with a new one. I had serious freezing issues with my first Epic and eventually had to return it for a new one. Second one has run perfectly since.

Agreed. Freezing is a hardware defect. Backup. Wipe. Check it out.
i've noticed this freeze always occurs on my phone when my it's idle. It seems to only occur when I leave the GPS on and it appears to be searching causing it to freeze.
My phone was working fine till a few minutes ago and now the center of my scream is not responding to touch, but everywhere else works fine.. Its locate in the center of the screen and it runs all the way across from left to right.
things ive already tried:
1. Pulling the battery /hard reset
2. Changed roms " miui, cm6, fresh"
3. Changed kennels "snap, kingklick, htc"
If anyone one have any other suggestion please do tell, thanks in advance
Are you using a program/widget that disables the lock screen?
Sent from my PC36100 using XDA App
Nope, no widget for lock screen unless you mean the lock screen that comes stock on the rom.
But its not the lock screen that iam having problems with, its like theres a dead spot on my screen and its not responding to any touch input.
Download a multitouch app from the market. Test it and see if you get any sensors where the dead spot is. If you don't maybe your digitizer is broken.
i tried dotty, and it registers the touch on the screen untill I run over the affected area then it just jumps pass it or not respond at all.. -_-... do u guys think i can just unroot my phone and get htc/sprint to replace the phone since it's a mechanical defect? i also have insurance on the phone.

Its not a mechanical defect.....but yeah they should be able to replace it. If you go through asurion you will have to pay the $50 or $100. Unroot the phone, take it to a Sprint store and show them the issue.
Sprint store will replace the LCD screen for ya. Result probably will vary how good the tech is.
I had it replaced once waiting close to 2 hours at the store, came home, noticed I can't hear a thing when making call while speaker phone worked. Went back to the store and asked for a new phone swap since I only had the phone for 2 weeks.
My phone was fully rooted with fresh rom, and ppl at the store didn't really care about it. They only checked for any physical damages.
Came back home, Unrevoked + rom manager = fully rooted in 20 minutes again.
Hello all. First let me state that I rather not make a thread to ask help on a problem that seems to have happened to a few owners, but my knowledge as to how I could resolve the issue is severely lacking..
At some point today my phone was ringing but the screen would not show. I thought about taking the battery out and turning it back on but there would be no HTC, Bootanimation, anything. It was Just a black-lit screen which responds due to tactile feedback and the four touchkeys light up as usual. At first there was an odd sound that would play after a few minutes so I decided to charge it but again there was nothing. Even tried to access bootloader with -Vol and Power still no screen.
I asked a friend of mine to call my phone to see if it would ring but they said it instantly goes to voicemail as if my phone was off. Note that I WAS SURE IT WAS ON.
Adb seems to work with it as it seems whatever I need to do I have to do it through there.
G2 rooted with gfree method
CM7.1 RC1
Clockwork Recovery
Again i am sorry if I bothered those with posting something others would think is "too common of a problem" as I have no experience in fixing this issue. Plus I would like to try any option available as I would not like to try and have my phone replaced (because of the risk of discovering root and obtaining a G2 with stock gingerbread which is currently not rootable)
Please help..
It sounds like you're suffering from some sort of hardware failure. You need to send your phone in for repair/replacement.

Same issue here...
I'm facing the same issue, when i try to unlock the phone (power button or trackpad) the screen lights but stays black, and the buttons are also backlit. I have to lock again with power button and unlock again to get to the actual screen.
It first happened a few days ago, and since i didn't reboot/restart in weeks i tried to reboot but the same issue comes back.
then i shut it down, pulled the battery and then back, and restarted: the phone goes directly to that black backlit screen, i tried several times and tried recovery with no luck, so i thought my phone was messed up although i did have some haptic feedback, well in fact the phone was actually booting, but just not showing anything else than the backlit screen; i waited a minute or so to the booting completes (still shows nothing), then i lock/unlock the screen again and there it is, asking for the pin code.
I tried to go to the recovery again to try to wipe dalvik-cache, i know for sure it goes to recovery, but with a totally black screen, not even backlit this time; the trackpad is too sensitive in the recovery to just blindly navigate in the menu, so it is not useable at all.
Then i had the idea to go to Rom Manager, i reflashed the rom from my sd-card, and enabling wipe dalvik-cache, which worked (all through a black screen). After a few minutes i "felt" it rebooting (vibrating) but still back to that black backlit screen, and i locked/unlocked it again and back it was asking pin code...
I also tried to roll back recovery to 3.0.2.4, since i remember i updated it a few weeks ago, but still the same issue.
I don't know what else to do without accessing the recovery, i wanted to try another kernel, or remove the trackpad wake... is there a way to do it via a script? I guess it's what Rom manager does...
Next step will be a total wipe, but i need to make some room on my sdcard for backup purposes first...
If anyone has an idea to sort this out, i'm highly interested...
I'll try to get a logcat, maybe could give a hint
Edit: Virtuous sense 2.0.0 (used it with no issue since it came out, could it be a hw issue?)
Edit2 : attached logcat
Is the pin screen differant than the usual one ie white number keys? If it is that's the sim lock screen you need to call the carrier to get the code or find out the default. Or just get a new sim lol
nah it's the 4 digit pin code, i didn't lose it btw, it's still working and i can use the phone, but i have a black backlit screen whenever i want to wake the phone, and thus when i receive a phone call, i don't know who it is and i blindly press/swipe the screen to answer, because if i want to use the same trick of locking /unlocking, it doesnt work as the lock button is also used to reject a call...
Maybe rip and reinstall the phone app?

I have the same exact problem as this EXCEPT, it's intermittent. Sometimes when I wake the phone I get an all black but backlight screen, and other times it's fine. I'm on CM7.1.
But a superwipe and reflash will probably fix it. Also don't restore system data on TB
I know i still can use wipe data + cache + dalvik through rom manager, and i always used to superwipe before switching roms, but how can i do that now when the recovery is all blacked out?
can anyone guide me to a script or something i could do while the phone is active, to tell him to reboot to recovery and flash that superwipe?
anyway i'll try the regular wipe and keep the thread updated

On my side if i leave the phone locked more than 30 seconds, it happens 100% of the time; also I noticed that now the backlight blinks 2 or 3 times (1 second blinking) when locked, first a few minutes after locking, and then randomly, about 3 or 4 times per hour; I guess it's getting worse;
I've read on another thread that it could be video cable getting loose, but since mine is still under guarantee, i won't open it right now just to check, if i can't fix by wiping / superwiping (when i know how to), i'll use that guarantee, which is one month left (lucky me)
EDIT: one other thing that makes me think it's no hardware, when the black screen appears because of a phone call or a message, the ringtone and notification sound are both half as loud as they should be, this is all really strange
after backing up my data, i reflashed the rom via Rom Manager, and I wiped data and cache (which equals to factory reset) this time: the first screen that should show the pin code numpad was already a black (backlit) screen!!
Also, thinking about it, i realised that the "flash rom from sdcard" menu in Rom Manager is in fact "Flash ZIP from sdcard": the zip doesn't have to be a ROM!!
So I tried flashing a new kernel this way, also some framework modifications (extended settings, removed TP wake, etc...) they all install Ok, but still this black screen...
Also I was about to flash SuperWipeG2.zip this way, but if it doesn't fix my problem, I will be stuck with a blacked out recovery, as SuperWipe wipes everything including /system; so if anyone has an idea to tell Rom Manager to flash two zips (Superwipe then Rom) i'll be willing to try, or a script to do that;
Maybe i'll have a look of the scripts in Superwipe and in the rom, and put both zips together... don't know if it's possible?
Maybe I'll try the Superwipe alone if I can get a spare phone, just in case...
Other thing:I used the phone's gps for more than 5 hours with the screen lit, and it never flickered even once; so it's hard to believe it's a screen connection issue...
Just to keep this updated, everything i did, including superwipe didn't change this issue, so i sent it back to the technical support (under guarantee) and I got it back today; the report that came with it says the screen has been replaced; so it was hardware finally...
Hi, i have same problem.. Black screen in recovery and during the boot. When the system boots, screen is OK. Sometimes i have also blackscreen when I want to use HW keyboard. I tried 4ext, reflash older versions of CW but still the same. I can see a screen through Android Screen Monitor and I can cotrol it. But phone is blak, only backlight. Can somebody say, how to solve this issue?
So, for other, if you cant see screen, you can use Android Screen Monitor for Windows and connect phone through USB and see a screen.

WAIT one minute... they don't care? where was I when this meeting took place?
I had this issue as well on a spare G2 I had.
The screen was just black but you could tell it was lit, hardware keys were lit as well.
The phone was actually my brothers and it rooted w/ CM7.
I ended up selling the phone as is on Ebay but after some research it was a failure in the hardware for the screen and I found extensive instructions on how to replace it that I didn't wish to do.
I never attempted to get it replaced and kind of wish I did now if they don't care about the device being rooted.
I purchased my G2 before he had his, and it's never had the issue so not sure what to think of it.

I used the same tutorial to change the LCD but after I put the new its just the backlight but nothing else... I will give it another go maybe and have a look again at those ribbon cables! I guess...

I found on ebay: HTC-Desire-Z-T-Mobile-G2-A7272-Slide-Flex-Cable-Ribbon
or I found also with the chassis for a bit more.
Thinking to buy this, it would be great if anyone could confirm that it would help "my condition" ?
THanks in advance!
In terms of cables, yes the flex cables are what you want.

Anybody ever have this happen to your MZF? Happens once every few days, and usually goes away after a few shakes. A few times I hard-rebooted the phone, and the display was still messed up in Recovery mode; the top half of the screen was affected but not the bottom. I could actually see the rows of static being drawn on the screen in big chunks. I can't remember if it was happening before the 7.1.1 update, but I think it was. Thinking it might be a faulty connection?
My phone did that around that time. It went away, but it's back now. Not only is it back for me, but it won't actually reboot. I can hear the splash screen (as if it was rebooting) however, the screen doesn't change. Still stuck with those crazy lines.
I had this happen... probably about 3 separate times. Each time there would be moments (either after tapping it, squeezing it, rebooting it) that it would flash back to a normal screen, then after about an hour it seemed to stay "fixed" probably for a month or two. The 3rd time it happened in the morning and hadn't resolved by the time I left work and stayed that way as I took it into Verizon. The Verizon guy took care of ordering the factory replacement at 7:30pm and it arrived literally the next morning. The crazy thing was that after I left Verizon it resolved and stayed "fixed" until I wiped it and sent it back in to Verizon, so I was able to copy and duplicate everything to the replacement phone.
While the screen looked like that, all the functions remaining intact, i.e. I could guess where I should tap and the sounds occurred that should have. I even attached my projector mod and the projector would display everything correctly even as the phone display was not.
I have not had the issue reoccur on my replacement phone.

Sounds like exactly the issues I had, functions intact even though the screen was janky. Luckily was still in warranty period from Moto so got a new one sent to me. (Moto customer service is the ABSOLUTE WORST by the way). New phone is working fine... so far.
