G1 Black screen, Cannot get to bootloader - G1 Q&A, Help & Troubleshooting

Hey, I have been given a phone off a friend to fix but it wont turn on. Booting normally, I get a vibration and then the backlight comes on but i cannot see anything. When i try to boot into the bootloader by holding the camera button and powering it on, the backlight comes on but nothing else. I cannot see the bootloader. Under both circumstances, I cannot turn the phone off. I have to pull the battery to turn it off.
Does anyone have any suggestions about a possible fix? Thanks

Havie you tried send when trying to enter bootloader? If it resets then you can still get to bootloader. If not, your friend has soft bricked and only way is to JTAG which takes strong hardware knowledge and steady hands.

ok im having the exact same problem. actually i thought it was a battery problem so i spent 77$ on a 3700 mAh new batter i guess tripple life... and got it yesterday booted gave same problems. black screen where T-Mobile should be yet the rom loads with scribble screen meaning u see part but it looks like the pixels are messed up. so actually decided to resort to what someone told me a Factory Reset so Pressing Camera + Power i got a Black Backlight screen yet wont show... and I cant turn it off without Taking out the Battery this has become a issue after installing cyanogen 5.0.7 T5... since then i Re-rom'd to superbad 1.2.5 same problem screen scribbles and stops im thinking did I fry it i dont even know how to google my problem because its pretty unique it isnt a battery issue its something in the hardware ... or am I wrong please send us some feedback... ill keep this thread in mind

Sorry, what do you mean by 'send'. I am a complete noob when it comes to G1's. I have worked out i can shut off the phone by holding call + menu + end but thats it. I still cannot see anything at all on the screen. I still only get a vibration on boot. How would I know if the boot has been sucessful but i simply cannot see?
Could the flex ribbon cable be nackered?

Black Screen

My Fiancee's G1 wont turn on at all,No T-mobile slpash screen or nothing.LED lights turn on and Call,Home,Back and Power buttons light up except for the screen itself her phone wasnt rooted,I have never experienced this before.
Can someone please help?
the phone is not turning on via the power(end) button???
try pressing the camera button and keeping it pressed, also press the power button to enter into hboot mode...if u succeed in entering that mode, the phone is fine, or else it could be bricked.
Try Home+Power see if you can get into recovery mode.
If you can wipe cache data.
Hi everyone, hope it's okay to post this here since this Question relates to mine.
I'm having a trouble like this except instead it's like my backlight went out, it was working fine until my alarm on my phone went off and when I went to turn it off I had to take the battery out of my phone because the screen wasn't pulling up. It flashed basically, so when I put the battery in the screen came on but no backlight. Could it be due to Cyanogen? I'm restoring my backup to see what else could I try?
could u be a bit more specific?phone is working??? calls etc???or are u stuck somewhere????
As I said, the screen came on but no backlight. The phone works fine except for the backlight I'm trying to figure out if it's a hardware issue or a software issue. I don't know how much more specific I can get really except that the only way to see the screen is to hold it at a certain angle so the light hits it just right.

[Q] G1 won't boot into

So I used to have a G1 until last year, then I gave it to my friend. My friend returned it in broken. Seems like she dropped it a lot. [typical drunk college freshman ]
Anyways, I had an engineering SPL, recovery flashed, and biffmod or superd [wow brings back memories] on the phone.
The phone won't even boot. I press the power button, no LED backlight. I plug it in, no charging LED. I changed batteries, nothing. Can't get into bootloader/fastboot/adb/recovery.
Is this a brick that can be repaired or am I SOL?
Does it even come on?
It does not come on.
So you are saying camera+power, home+power, etc... will not take you anywhere?
What come up when you press those ket sequence?
Like I said, I am unable to boot into fastboot/recovery/normal boot. I don't even see the G1 logo. The LED back light doesn't even turn on.
I thought with a brick you're still able to see the G1 splash screen, so I don't know what to call this.
Looks like you have a black screen. Since you said that your friend drop it constantly it must have broken a wire or something that cause the screen to go black.
Bleh. So much for practicing cooking ROMs with that phone :[ thanks for your help!
Doesn't seem like a JTAG or whatever can fix this issue.
does the light go on when you charge it? or plug in a usb?
could be a dead battery..
From the first post
"The phone won't even boot. I press the power button, no LED backlight. I plug it in, no charging LED. I changed batteries, nothing. Can't get into bootloader/fastboot/adb/recovery."
any other suggestions?
well what im saying is maybe the battery is completely dead... did you try booting while plugged into a charger? lol stupid question mayb but im jus trying to cover all fields before we assume you have a brick
Lol. Like I said, I changed batteries. As in I replaced it with another one.
And yes, I did try booting with it charging, which is why I noticed there's no charging USB

ooo ok... dam that sucks, im not sure what else it could be. unless you dropped the phone a lot lol
Am I able to fix it with a JTAG? or is this kind of brick unfixable?

Screen stays black! Audio and touch are responding.

Hi all,
I woke up this morning and my note's screen hasn't been working. I didn't drop it or spill anything on it, it just doesn't turn on. I know the phone is on because i can hear and see the capacitive buttons light up when i touch them. Does this mean i need to replace the Super AMOLED/digitizer unit?
The only thing i can see is the white Samsung logo (very faintly at that) when its booting up.
I found a site that sells replacement units but i don't want to buy it unless i have to.
I need some advice.

Hey thanks for the reply. But i my phone is not even rooted. it was working fine last night.. the only thing i did different was i didn't charge it over night. So i thought at first it was a battery issue. I'm so sad... lol
sounds like the backlight is burnt out... unfortunately this is not something that can be replaced itself... the digitizer/lcd will need replaced. now is the fun part... either find the country your note is made for and mail it to the warranty dept, or have it fixed by a reputable repair shop out of warranty...
No need to have root, to go to stock recovery
Just switch off device, keep holding vol up + Home + Power
when light turns, release power button, but keep holding other two.
If you able to enter in recovery, N can read on screen, means screen is intact.
wipe cache, wipe data
N still error remains, flash Stock ROM

[Q] HTC Vivid Black Screen... :(

I don't really know what happened. When I press the power button my phone's screen lights just black then goes blank. When I press my buttons they vibrate but nothing happens. I've tried pulling the battery out several times, leaving it on the charge and all other kinds of things. It is just not working. Does anyone have the solution to this problem?
I'm not sure if this is the same issue..but along the process of rooting my rogers raider I encountered thus during a regular restart. I thought I bricked my phone but realize that the back light was just off and my phone was actually in the recovery menu. I put the phone under bright light and I could just barely see the headings in the recovery menu. It took some tilting and angling the phone just right to see it, but I was able to run a nandroid recovery and get back to a point before this happened. Once again, not sure if its the same thing but try tilting the phone around and using the volume keys to see if you can see the recovery menu in the blank screen.
Hope this helps

This doesn't seem to be the situation I'm having but thank you anyway. +Thanks.
when you plug it in to charge, does the orange charge light come on for 4-5 seconds then go out again? have you tried to hold the vol down key and the power button to get into HBoot? If you can get into HBoot, you might be able to get into recovery.

Yes, that is exactly what is happening. I tried what you said but it is not working. My phone won't go into Hboot.
I think your battery isn't charging (at least that was the issue I was having). Your battery will only charge when the orange light goes on, and if it's anything like what was happening to me, when the orange light went off, that's when the buttons would vibrate. If this is the case, it may sound tedious, but you have to watch the phone. When the orange light goes off, push the home button several times and the vibrating will stop. Then you should see the orange light come on again to signify the charging state. It'll go off again after 4-5 seconds and the buttons will vibrate. Repeat the process of pushing the home button and letting the orange light come on and eventually, the phone should try and turn on. You can try and see if it'll boot, but mine never had enough juice to turn on. So I would pull the battery when the HTC Logo came up and repeat the process with the orange light. This time though, I would hold the vol down button knowing that when it tried to turn on again, it would load into the bootloader. I can't guarantee this'll work for you, but give it a go. What might make it easier is borrow a charged battery from someone and see if it'll load into the bootloader. That might save you from that tedious process.

help the charging light doesn't come back again.. vibration has stopped.. but still no charging light
help pleaseeee
Try different battery fully charged and see if your phone turns on. It it does then plug your phone for charging and see if charges.
Try connecting your phone with usb cable in computer and see if your computer recognize the phone.
there can be three issues.
1. Your battery is dead and won't charge
2. Your charging port on phone is not working
3. your phone backlight is not working.

EDIT: I have stopped looking for these threads. The more I look, the more I find. If the above threads don't convince you that there is a serious issue with the vivid, then adding more of the same problem will no longer help.
I have added this thread to a growing list of similar threads. Please read the other threads and see if your issues seem familiar.
From what I understand... Don't let your battery run out on this phone. Some Vivids kill batteries.
Solution? None yet.
1. Buy a new battery once a couple of months-ish, until someone figures out why some Vivids are eating batteries. YMMV
*OR*
2. You might invest in a external charger and see if that can bring the "Vivid munched" battery back to life. YMMV
I vote to thread merge the above threads if this proves to be the issue.
Hello
I hope to get an answer here to avoid a new thread. I was trying to return my vivid back to gb from ics. I had booted into the bootloader and i dont even remember at this point what i thought i was going to do. I think i got distracted. But anyway i pressed vol down to boot recovery because i was going to do a backup and i looked away from the phone for a minute and when i came back to it the phone was black screen. i hit the power thinking it was just on standby but nothing. I notice it was backlit on the screen but nothing would happen when i press anything. I pulled the battery waited a few min put it back and now totally black with no activity at all. no lights no vibrating no power on, no adb. I have played with a lot of phones and even iphones too so if this thing is fried i guess i will consider myself lucky that its the first ive actually killed out of probably 30 phones. I have searched and tried many things but i cant believe there is no way to recover it. I have recovered a lot of phones I thought I bricked before. any help is greatly appreciated. I was on ics and rooted. I also relocked the bootloader. (i was planning to go back to gb) I thought i had a recovery installed but maybe not. i posted in another thread that i was unable to get hboot by power + vol down method. i could only do it through the tool kit. so i dont know if any of that matters

I hope someone resolves this issue, I've messed with lots of phones. But this is really weird. But I got the same problem where all that happens is that there is backlight on but no boot IMG no HTC logo, no bootloader, recovery. Completly non responsive. At first it wouldn't even power on until I would unplug from a power source. Whether it was unpluging the charger or removing the battery. That's when the backlight would flash. All this happened in the process of flashing a PH39IMG.zip
Is there no other fixes for this? Anyone? Please

I once got stuck on the HTC screen (White background) and found out I could access the device in adb.
So, connect your phone to your pc and check if you can access it from adb (adb devices). If you can try get to the bootloader from here and see what happens (adb reboot-bootloader)!
And if you can access bootloader,
>If you need to get back to stock, get your carrier RUU, put rom.zip from it in an external sdcard and use reboot into hboot again, OR
>if you need a custom ROM unlock bootloader, flash a custom recovery (TWRP is cool) and you may use TWRP to install your ROM
I hope this helps... lets know...
I did mention I cant get it to recognize the phone. So no adb I tried all that before posting. Im afraid im just dead
So I am having the same problem. I eventually got it on yesterday but I turned off my phone and I am back to square one. Would using the vivid toolkit work to reboot to hboot? or am I stuck like this until i replace battery?
4 hours later I am back on!! never turning this thing off again
Had the same problem and just left the at&t store and its the battery. Once he exchanged batteries it worked fine

ok so i've been using it a bit but my battery was 70% last i checked. was playing around with throw and just opened youtube and the screen flickered a bit (black lines) then decided to go black completely.
nothing i do will make the screen do anything.
holding the power button for ages (usually the way to turn off/reboot a phone) doesnt do anything. the backlight is on as i can see that. but nothing is on the screen.
anyone got any ideas on how to force a shutdown/reboot on these?

IIRC the Xperia Z1 has a hard reset button under the sim flap, it's a small red button, give it a shot.
remove sim card and sd card and try again, if it's still not responding do an update repair using SUS or PCC
BTW there is a known fault with the XZU and it could also be on the Z1 as they use similar Firmware, what people have found is that the phone will start up eventually and then they go into the display setting and untick the auto backlight option and that fixes it
I also reboot my Z1in this way when it blackout.

Put it on charge overnight but it doesn't see,m to have taken any charge at all....just trying again using diff PSU and cables but it doesn't want to charge. It recognises that I've out a cable in as I played with the smart connect setting. When it is off completely I get a red light (presumably meaning its charging ) but not in android
Any ideas?
Got it charging again by pushing the red button near sim slot for a couple seconds.
Just had another issue with SD card not being recognised after I removed another (/safely) had to reboot again using power plus vol up as it stuck on the shutdown logo when I tried to power down'...
Wow I can't believe the amount of issues I've ran into within 24hours of having this thing. I really don't know what to do...return it because it sounds like a faulty device (but all the issues are seemingly unrelated) or return and get another phone (is anyone else getting problems like I am?)
Sometimes phones have issues. I got one once that had no speakers or Mic inside... it happens lol
Try to go exchange it, and see if the next device gives you issues.. if not then you're good, if it does pick a different phone..
Do it soon though, most carriers only have a 14 day exchange period, and then after that will charge you all sorts of fees and try to fix your phone rather than just giving you a new one....

sounds like a similar problem I had with my 64gb SD card - as I mentioned above remove all cards then start from there - a reflash of the firmware might help also

Something happened to mine with Youtube too. I'd started a video and paused it on a frame for comparison with another screen. While I was setting the other phone up, the screen on Z1 timed out. I pressed power, the screen come on and flickered, then went black!
Power and both volume keys function the same as the red button under the flap. I wasn't able to reproduce the bug.

yeah i've been trying to reproduce it and failing to. very odd. maybe its something to do with the first time you use youtube and do something specific?
gunna phone o2 up tomorrow and see what they say about all my issues. seems to have been fine this last 24 hours though and in their eyes that is prob reason enough not to issue a replacement.
I've had mine since Monday and this happened to me yesterday. I was troubleshooting sending MMS with T-Mobile tech support (not a phone issue as it was happening on previous phones too) and had to restart the phone several times. I noticed upon restarting that the backlight seemed to be on but the phone was not booting up. Had to perform several hard resets (both with the red reset button as well as the power/volume up buttons) before it FINALLY rebooted and stayed on. While trying to figure this out I ran a Google search to see if others were having this problem. One solution was to make sure the backlight option is checked. I had been messing with settings the night before and must have unchecked it. Since I rechecked it I haven't had the same issue.
