Strange (and a little worriesome) behavior on my G1

Tonight my G1 displayed some very odd behavior. It was running normally and I pressed the power button to make it sleep and I set it aside. About half an hour later I picked it up and tried to turn it on by pressing menu. The phone gave no response other than lighting up the five buttons on the bottom. I tried sliding the keyboard out and the keyboard lit up as well, but the display remained black. Plugging it in via USB to my computer did absolutely nothing (no sounds, no notification light, etc.), and I got the same result when I plugged it into the charger. I finally decided to take the battery out in order to turn the phone off, and then put it back in and pressed the power button. The phone booted up normally, and now everything seems to be working in proper order. I am slightly concerned, however, as I have never had this behavior in the year that I have owned my G1. I am running Cyanogen 4.1.999 with the Hard SPL boot loader. I am unsure whether this behavior has anything to do with the mod and I am wondering if anyone else has experienced anything similar. I do realize that if my phone is bricked it is my fault, and I want to determine if this was simply a freak accident or if I need to do something differently with the phone.

first of all if your phone was bricked you wouldn't be able to use it. as for your problem it doesnt sound too serious so if i were you i wouldn't worry about it. but if it does happen again reflash your phone and if it happens after that, pitch it to cyanogen to see if there is a problem with the rom.

I do realize that it isn't bricked now, but I am worried that this behavior could mean that I am pushing the phone too hard. I am mostly curious as to whether or not anyone else has experienced similar behavior from their G1.

Turn off compatibility mode in spare parts.

don't worry this is a common problen It happens to me all the time any hero I flash plays nice for about a day. and then boom no problems with cyan!

I had the same problem, but unfortunately my G1 is still not working properly.
In the morning, turning off the alarm I left the phone for 5 minutes. An attempt to turn it on did not work: there was no reaction on display, although the buttons were lighting up. I restarted phone taking the battery out and now I have following:
- keyboard fully closed: no reaction/black display, buttons are lighted up
- keyboard open: I can do everything: change ROM/make call/write messages/Internet/GPS/... - everything what is possible to do with rooted G1
- keyboard partially open (visible only lowest row with such buttons as ALT, SHIFT, SPACE): similar to 'open' but with changed orientation
Can anyone help/advise? Did almost everything: ROM changed, full wipe, recovery

[Q] Massive Problems

Hey all,
I just installed a new digitzer on my Vivid. Everything went fine, and nothing broke as I was taking apart the phone, or putting it back together.
Now that the phone is back together, however, it is having some problems.
First off, When I try to power the phone on, it vibrates like usual, but then doesn't display anything. The phone then proceeds to enter in to a bootloop and keeps vibrating every couple moments. When plugged in to the computer, the orange light comes on for a few seconds, then turns off. Windows will not recognize the phone. All the while, the screen is completely black, and none of the lights come on for the buttons either.
The phone was working fine before replacing broken digitizer.
The phone is NOT rooted, nor has it ever been. I am running stock ICS.
have tried entering Hboot with no avail.
Any advice?
Thank you!

Can you get into any other modes? Try to get to hboot(hold down power button and volume down) while plugged into computer. Should take it to fastboot.

how long for? I tried holding down for a good 30 seconds...nothing happened other than my orange light turning off

I noticed with mine I had to go with:
Remove battery.
Replace battery
hold vol down + power
few seconds later release power
few seconds later in hboot
YMMV due to repair.
You can also try a knoppix boot disc and some tutorial to see if you can find any sign of life off the phone in dmesg.
hope this helps some.

Sounds like a loose connection. Make sure that you've correctly reconnected all internal connections. Especially the connection under the little door with the void sticker on the screw in the battery compartment. If after verifying all connections are made and proper, the problem persists, I'm sorry to say you may have physically damaged the connectors during disassembly. Please visually inspect all connections for damage. A powerful magnifying glass is recommended.
(I have successfully replaced my digitizer twice, and my LCD panel once on this phone...)
Sent from my HTC Dark Raider using XDA.

I have taken it apart twice, checked all connections, and everything is good. Phone cannot enter any boot mode, and computer still doesn't recognize it. The orange light still only stays on for a few seconds when plugged in, then turns off. The phone then proceeds to keep trying to restart itself, but the screen remains pitch black blank

idk.. get a replacement.?

[Q] Help - Power Issue with LG-P999DW

Hello,
I'm hoping this group can offer a few suggestions to resolve this problem.
Situation:
My wife's LG-P999DW phone appears to be having severe power issues.
It is set to go back to Wind Mobile for a replacement. However she has photos on the device that she needs to retrieve - apparently the SD card was never initialized so the photos are stored in the phone's memory.
The phone is completely stock and was picked up new in November 2011. I have not rooted or modded the device in any way.
Unfortunately the power will not power on. The charger makes a high pitched humming noise when plugged into the phone. At this point I've tried directly connecting it via both the USB cable that came with the charger and another separate cable to my iMac.
After lots of searching on the this board I discovered that the phone does have a recovery mode (Volume Down & Power button). The phone launches the white LG logo and after about 3 seconds the screen flashes and goes blank before recycling to the LG logo again.
At this point I'm desperate to figure out a way to access the memory on this device to try and retrieve these pictures (basically pictures of a pet that passed away that were not unfortunately backed up).
Any suggestions are welcome - I'm open to all options.
Thanks

Interesting problem. If the phone is hosed, then so of course are you, so let's assume it's not.
Since you say you get some activity when holding vol-down + power, you can try to install clockworkmod on it via nvflash, boot into that, mount usb and if you're lucky you'll be able to copy the images. (If you only get this blinking when it is plugged in you can ignore the next part - you will not be able to boot into CWM.)
To try that, find a guide for P999 on how to install CWM via NVFlash (this is the P990-thread).
I would not get my hopes up, since it will not start the built-in recovery by itself then the entire internal storage may be hosed (including the partition with the pictures), but it's worth a shot.
You may even be so lucky that it's only the charging curcuitry that is damaged (I assume you get the blinking lg-logo when it's plugged in only, which a phone without a battery will do), in which case you can borrow a charged battery in a phone store and copy the images from internal storage to an external sd-card there.
If the entire power-delivery system is damaged, your only hope is to beg and beg the support people to ONLY repair the electronics and not do anything else to it (wrap the phone in a big please-note).

[Q] Nook HD+ won't boot

Hi all,
I bought a Nook HD+ around a year ago, and installed CM11 and CWM recovery on it. Everything worked fine until coming back from a trip in June, when I noticed that the power button required several tries to power on the device. I thought nothing of it until I came home and found that it wouldn't turn on at all, having tried all the button combinations and power cycles suggested in these forums. Now here's the strange part: I believe the internal eMMC may be corrupted because a) there's no battery icon when plugging it in. and b) when trying to turn it on, the screen is clearly on for a couple of seconds. It turns grayish and I can see the edges of backlighting, but there's nothing on it. Also, it won't boot from microSD or show anything on the screen at all. So, I have two questions: 1) What is the cause of this problem, e.g. broken screen or bad memory, and 2) What can I do to fix this? The tablet is just out of warranty, but I do live relatively close to a B&N store.
Thanks in advance,
sgamer395

H811 won't boot after multiple battery pulls... HELP!

So I can't boot my phone. Previously stable h811, unlocked bootloader running latest 20i Extreme 3.3 MM with G4 Tweaksbox. I have a Qi/NFC sticker on the back, but which has worked flawlessly and was not in use when the phone died. Here's what happened and what I have attempted.
Problem began when phone simply went black. The only thing running was Maps, which had a route displayed but was not in navigation mode. The screen went dark like normal, and when I went to wake the phone, nothing happened. I was in the car and tried plugging in the car charger and did not get a charge light. Pulled the battery and was unable to get a response. The phone and battery were quite warm.
When I got home, I tried a different battery, and the screen turned on to the LG initial boot screen, but nothing else happened.
After many battery pulls and attempts to boot into recovery, I tried it with the phone plugged into the computer. Finally, it showed the charging screen and light, and after several more attempts- pulling the battery and inserting it, then powering on, it appeared to be booting, (boot animation started, but then looped and froze on the initial boot screen (with bootloader state: bootloader unlocked in the upper corner). After another round of attempt/battery pull, it booted all the way up, but at that point I had my sim pulled. Pulled the battery and tried to restart and it froze on the initial boot screen again. Haven't been able to get into recovery at all, can't get into download, can't boot past the initial LG screen. Sometimes it loops, sometimes it just hangs. Nothing I do pressing combos of buttons, plugged into computer or unplugged, seems to change anything. The very farthest I've gotten is the breathe blue light before the boot animation, but then it looped. Now it's boot looping plugged into the computer.
Any ideas? I'm at a total loss.

Black screen of death here too
Yesterday, I was using Chrome, site loading, screen just went black. I had about 1/2 battery at the time. I figured maybe the battery was just reporting wrong. When I got home, swapped batteries, same issue. I've been able to get into recovery and attempt a factory reset a couple of times (after many frustrating attempts.) The phone seems to only be able to be powered on for about 30 seconds before it goes black again. I'm going to attempt to fix with download mode now. If anyone else has solved a similar issue, any tips would be appreciated.

Hardware appears to be at fault!
Check this out, people!

Spread the word. Sounds like this is our problem. Apparently affecting mostly models with serial numbers starting 505xxxxx... which is what mine is. Called LG and they issued an RA# and shipping label to send it to them for service. I'm a little concerned since I didn't buy mine through a carrier, but this seems more like something of a soft recall than strictly a warranty issue, so I'm hoping they fix it no questions asked. I'll keep you guys posted on the progress.

Same thing happened to me today. My phone randomly shut off and it won't boot. Its stuck at the Android logo. I wasn't messing around with it. Just normal use (Snapchat, youtube). I tried booting into recovery but it just goes back to the android screen LG logo and keeps looping. I at least want to wipe the phone before I send it (personal info).

Same here. Mine has serial number starting 505, was purchased back at end of 5/2015 with not problems until this. I filled out the warranty repair form on LGs website and they sent me an RMA with label to get it fixed. I sent it in, they sent it back, and the only thing I see is on one sheet they printed out and included in the package said 'replaced board'. However, when I started up the phone it looked like new initialization with xx of yy apps initializing and then it began bootlooping with the LG splash screen. So frustrating!
So, this time I contacted t-mobile via their online chat, and did a warranty exchange through them. They will send me a replacement LG G4 next day ups air and I will send them the defective one for them to claim warranty themselves. We'll see where this goes. I might just take the replacement unit and do a tmobile jump exchange to another device. I wanted to wait for the new line of HTC nexus phones that are rumored for this year (and was loving the LG 4 until it died), but I might need to just jump twice this year and go for something like the new Samsung S7 of new LG G5 now and then again switch to HTC nexus once that comes out.

Sent mine to LG, and they fixed under warranty with no questions asked. Got it back within a week. All good now.
