[Q] Mt4G won't boot AT ALL - myTouch 4G Q&A, Help & Troubleshooting

I went out for a while with my battery at 20%, when I came back it had drained out. I put it to charge, but when I tried to switch it back on, it refused to boot. On a normal power button press, it would vibrate 3 times and then the red notification light would start blinking. Same thing with power + volume_up. If I press power + volume_down, it would vibrate 5 times and the green notification light would stay lit. Nothing comes on the screen, whatsoever.
I was rooted with S=off, and was using the Operation Inferno ROM (which I have been using comfortably for the past month or so).
I did try some stuff with ADB, such as using it to reboot into bootloader and recovery (same 3 vibrate + red notification light), pushed the Operation Inferno ROM again to the sdcard and tried to restore the ROM from that location (for which I got adb: unable to open file /sdcard/backup.zip).
I haven't yet gotten around to downloading and installing the factory image some have suggested for the eMMC issue (PD15IMG.ZIP) but I wanted additional opinions considering most people with an eMMC issue have been able to open HBOOT at least.

When the phone doesn't power on, neither ADB nor fastboot will help you. There is no device on the other side, so all your attempts went to the drain, and it was expected. Nothing to do with eMMC issue or anything else. Your phone just doesn't power on.
Put your phone to charge, if the light turns orange - just leave it to charge until it's green, then disconnect and try to power on.
If the light doesn't turn orange, or it doesn't power on even after charging - remove the battery for 10 min, press Power button for 1/2 min, release the button, reinsert the battery, put to charge. And again, let it charge before you try to turn it on.

I did charge it earlier (for about half an hour or so) and the orange light does come, but it didn't boot after that either.
I'll just give it a try by charging it through the night and see.

I think a key thing is to take out your battery for 10 min, as Jack_R1 suggested. Then proceed with the charging.

Still doesn't work. I dissembled it and kept it like that for quite some time, then put everything back and charged it for hours. Still the same issue happening during boot.

Connect the phone to USB, powered off, see if the PC recognizes "QHSUSB_DLOAD" device. Try to power it on, see if it happens.
If it happens - it means your primary bootloader is screwed, in another words - no repair (actually, repair is theoretically possible, but no guide, no information and no sources exist for MT4G).

When its plugged in, its recognised by the ADB (even when powered off), and I can do some basic commands (mentioned in the first post). When I power it on the same thing happens as when it wasn't plugged into USB (ie, the vibration and the blinking LED).
I'm also worried about water damage, since a very tiny amount did come on it as I was sweating profusely. Although the indicators in the battery tray and on the battery itself don't signal damage (they're completely white) I've just decided to try and keep it opened up in a bowl of rice, just in case, until someone is able to come out with some idea.
As I'm in India, taking it to T-Mobile is not an option. If nothing works out, I might take it to HTC and see if they can help out.

Charging problem ..

(Bare with me, this IS wm6 related)
Okay, so i got this qtek 9090 from a trade online, and the owner pointed out that he had used it for some time now and it worked without problems.
However that seems not to be my experience. At first I was a little worried that it did not came with a charger.. Only a USB cable. No worries i thought, I will just charge it through USB. Now I have had some experiences where phones wouldn't charge from some of my computers, apparently because of some boards that put out lower amps than others. However I knew atleast one computer should have no problem charge ordinary cell phones.
So i plugged it in, and to my worries the battery kept going down... Untill the phone was dried from power and everything got lost again.. and again.. and again.. It seemed a little odd that it apparently deleted everything each time, since the backup battery indicated 100%.
So at last it went into flightmode and I shut it down with the powerbutton and let it be connected.. The first many hours nothing happened.. But suddenly, when i did an occasional check, it said 3% battery. I went to sleep and the next morning it was fully charged. I used it all day in school and it held its power real fine.
Now I got the feeling that this probably was caused by the low amp output from the computer, making it unable of charging to the extend where the phone would still be able of running whilst charging. So i figured i would order a 220v (the powercurrent here in Denmark) -> 5v USB that outputs 700mA, to make a quicker charge.
Well, to day I was gonna receive that adapter, and since I'd read that the wm6 apparently draines the battery some bit, I waited untill today to upgrade to wm6.
I upgraded and everything truely runs quick and stable. But when i recieved the adapter and plugged it in, i was horrified. The power kept going down, as I had experienced when it was plugged into USB.
Now my girlfriend really wanted to play bejeweled on this thing, so she did and then shortly afterwards we took a few hours nap. I had her plug it in the new adapter to charge it. When i woke up i saw the screen blinking.
I could se it was rebooting over and over again, as it had done the first time it completely lost power..
Now besides that extremely annoying charging problem, I now had another concern....
The boot screen shows NONE next to the R and the G.
Next to the D is the wm version displayed.
Any help would be greatly appreciated.
red LED?
Hm.. By doing a hard reset it shows numbers next to R and G again.
It continuely reboots, display boot screen, shuts down, LED is red, reboots, displays boot screen, shuts down, LED is red again and again.
If i hard reset it some times it will at one point stay off, but the LED still lights red.
And now I question wether 700mA is even enough for charging the BA?
1. Higher power given by power supply does not mean, you will get faster charging
2. If you use WM5/WM6 and have Bluetooth turned on, device turns on every few minutes (bug/feature of the driver needed to keep Bluetooth running: look for BigMike's fix for more information). If your deivce is set up to turn off after long time (for ex. 5 mins), battery might drain out in half a day.
3. Check power settings (delays for device power down etc.)
4. In WM6 be sure, that audio manager is not running (prevents device from deep sleep, allows only screen shutdown)
5. If battery shows up 100% and after disconnecting device discharges in less than 2h being turned on all the time (wifi, bt, phone, screen all the time turned on) it means, that battery might be worn. Consider exchange.
R and G showing NONE is normal in WM5/WM6 because of bug (unfixable for now) in the device and it's incomatibility with this OS: after turning on from power down (taking battery out or total discharging) make soft reset just when R NONE G NONE shows up on the screen. Everything will be normal.

AFAIK the lower the mA output, the slower the charge period.
I have had wifi, bluetooth, beam off. I've set shutdown to 2 minutes. I've set it to low brightness and etc.
As i mentioned it had no problems going a whole day of usage in school.
Didn't know about the bug in wm6 that makes only the screen shut off, but at the momemt i can't even boot the device, apparently because it has no batterypower. And having it connected to the charger makes no real difference (other than it will display the bootscreen and perhaps even the Windows Mobile welcome screen thing, for a few seconds.. then go dead again.)
I've had it in the charger for about an hour or two, still not enough power to boot it up.
It feels like it's just not charging sometimes.. And other times it will charge just fine.
Found out about the reset to solve the NONE issue, but i still don't know what it means that its LED is red all the time?
Even 500mA is enough for sure, as charging from USB works fine.
Device will shut down soon after turning on if there is not enough power in battery, even it if is charging. Leave it charging (amber led on the right) for some time. RED led means low battery and no charging (AFAIR).

This is not a bug - thanks to this you can still listen to your music keeping device with screen turned off, when you don't need it to spare battery.

Red LED (right one) means low battery, no charging. To charge this led must be amber. Details - you must look for manual.

Okay.
It's odd still. When i connect the charger the right LED starts to light red.
If it means that its not charging, there must be something wrong, since it only happens when connecting the charger..
it can be amber or red. Those are different colors and meaning.
You can confirm it charges touching the battery - it becomes slightly warm after some time.

I KNOW that, but it is not going amber. It stays red all the time.
Found this thread that discusses a similar problem; http://forum.xda-developers.com/archive/index.php/t-233782.html
Apparently it shows RED light all the time if the battery is dead.. However i hardly doubt that the battery, which could power the phone just fine for and entire day, should be dead.
However, one suggestion in the thread was to take out the battery for some time and then try again. So I will do that for now.
Behavior has changed a bit now..
The LED is still red when i connect the charger. However, if i try to turn it on following happens:
Boot Screen shows for a couple of seconds...
Windows Mobile startup screen appears and the LED changes to orange/amber..
After a few seconds the screen turns black and the LED changes to red again...
And then after a few more seconds the boot screen appears again and everything is repeated, over and over.
If I disconnect the charger the boot screen appears, the wm startup screen appears, this time with a flashing red LED.. shortly after the phone turns off.

I've seen this problem before. The charger is not putting out enough power to both charge and boot the BA. So what happens is that it starts charging enough to start boot, but as soon as it has enough power to start the boot, it immediately drains it by starting to boot with screen at full brightness.
What I do in this case is to try to catch it just as it starts to boot and turn the backlight off by holding down the power button for 5 sec. This turns off the backlight so there is less drain and the thing can boot up and start charging.
All in all, its a pretty stupid bug but what the hell, there is a solution to it.
Good luck.

This seems to work atm. (just a few seconds since it successfully booted)..
Does this mean that the device really cant charge if its not "on" ?
(I can see its booted and the LED is now orange. If only it will stay this way untill it has been recharged further ))

It can charge when it is off. BUT... When its off, its not really off... It has to finish booting and then you can turn it off. Then it will charge faster as it only has minimum drain on the battery. As I said before, its a stupid design.

Well we can certainly agree on that
So does the phone also basicly use to much power to be used and charged at the same time? Which would explain why it seemed to lose power even though it was connected to the charger.
Although it still doesn't add up for me, as at one point i was playing a game on it, while charging and then it charged real fast, where you would expect it to use more power
Oh well, if only it keeps charging now i'll be glad

I have found that if you only use the USB cable to charge, it takes much longer (if at all) to charge if it is on. Thats why I bought cradles that have external power suppies as well as the USB sync cable. With this configuration, it gets to full charge in about 90 minutes.
Hm.. yeah.. I let it charge for some time, until it shut down and the LED changed to red again.. The same thing has happened about 3 times now.. If I try to navigate it with the brightness off it will shut down after a few clicks..
Seems like either the battery is completely dead or it's simply not charging.. :/
Think i have to buy a new battery and a cradle, although i didn't really want to spend money on this phone as i got it virtually for free (through a trade of a w810i)

Get it to orange and then push the power button (short push) to turn it off (not long push which only turns off the backlight). Then let it charge for an hour or 2 (or even all night). By then, it should work OK.

Yeah, i tried that. As soon as i press the power button it goes to red again.
Update..
A litte update (i might as well document everything I find out here, if anyone should run into a similar problem).
Now, I've had the device connected to the charge for some time now.
What happens is that the device boots up, automaticly dimms down to no light (since i once had hold down the power button, to dimm down light).
Then it boots up, and i can see everything running.
I can navigate to the battery status menu, which shows
Battery: 0% (charging)
Backup battery: 25%
After a few minutes the device shuts down, and the LED goes red again. But after about a half a minute it will try to boot up again, and it goes through everything again.
What I've noticed is that the backup battery slowly increases, and while im writing it has gone all the way to 75%. The good thing about this completely automatic procedure is that it apparently slowly charges, at least, the backup battery.
My theory is that the backup battery has first priority in the system, so that the regular battery wont charge untill the backup battery is up. And since the backup battery can't apparently be used for actualy powering the system, the system will continuesly reboot because of lack of power, theoreticly untill the backup battery reaches 100% and it starts to charge the regular battery.
The whole problem seems to be cause by some charging malfunction, so that both batteries has been completely discharged. I hope that by letting it continue to reboot, charge, reboot, charge, etc. it will revive the battery.
I will return with more info tomorrow.
Any suggestions are still greatly appreciated.

Flashing red led of death

Hi everyone, yesterday I took my G1 from my pocket (after using it normally for some hours) and it was turned off. I thought the battery was dead (I left it at about 20% charge) so I tried to turn it back on and surprise...no vital signs at all. The phone didn't turn on, and the led was dead. After losing half of my hair, I tried removing the battery and placing it back. Now the phone behaves like this; when I press the power button, as long as I keep it pressed the led flashes red and that's it. When I stop pressing the power button the led stops flashing. When I plug the usb cable, the led gives a solid red and stays like that forever.
Please someone tell me it's just a screwed up battery...please

Probably bad battery. It is certainly worth it to at least try another battery -- they're dirt cheap anyways, or better yet, BORROW one.
* Solid green (when connected to the power adapter): The battery is fully charged.
* Solid red (when connected to the power adapter): The battery is charging.
* Flashing red: The battery is low and needs to be charged.
* Flashing green: There is a new notification.

Leave it to charge for 30 minutes or so, then try to power on. should be okay
better to charge from ac power if u can
Its possible your charger could be faulty.
I have the same problem, has anyone found a solution?
Try leaving it charge for a good hour, or just go out and try a new battery, could just be dead.
Sent from my Xoom
sometimes if a battery gets to low it wont even charge... not just for phones but cameras too and so on..... iv had to do this to cell phones and cameras.... take a usb cord you dont care about and cut it and expose the red and black wires..... look for the positive on your battery and negative, usually its marked, how positive to positive and negative to negative for 30 seconds to a minute while its plugged into the computer then, pop the battery back into the phone and try to charge..... everytime iv had to do this for a freind or something of my own the battery has lasted over a year after with no problems.... just a suggestion
Thanks for the suggestions. I had already ordered a new battery and the phone boots up with it but it won't charge on or off and usb isn't recognized either. I tried wiggling the plug around to see if it was some kind of loose connection but it doesn't appear to be the case. I may take the phone apart and see if anything is loose but otherwise I'll just have to enjoy the last 30% battery of G1 time I have.

N4 Bricked!! No responses! Just red led when I plug in to AC/USB

Hello guys, first than nothing, sorry for my bad english, isnt my native languaje. I got this problem yesterday in the night of the new year!!!!!!!:crying: I was rooted, using Xylon and Faux Kernel, but the problem appears from nothing!!
The first thing that I detected was, the phone take a WHILE!!! for charge.... then, out of the power, the phone get overheating and discharging so fast, never in life that happends, when N4 got discharged i try to turn on again but download mode appers in the screen, finally I get in the recovery, then I did a wipe cache/system and factory reset. Install again the Xylon... but when phone finally turns off, when I plugged in to AC absolutelly nothing happends, the led just turn in red, and the N4 dont start in FB, dont get charge, dont do a sh*t !!!! I conect it to the PC but also nothing appends, the N4 doesnt appear in my device list.
So... my N4 its broken?
There was possibly something wrong with the kernel and rom combination that caused your phone to overheat. I think eventually the heat may have damaged your hardware. Sorry but, if something was wrong in the first place it was not a good idea to reinstall the same thing that was causing the problem, if I were you I would have flashed a stock ROM. My only advice now would be to RMA it and pray
EDIT: I found this if it helps at all:
If you are unable to access the settings menu of your device, you can still reset your phone by performing a Hard Reset. Here are the instructions:
If your phone is on, power it off.
Press and hold Power until the device powers on, then immediately press and hold Volume Down (while still pressing Power). You will see the word Start with an arrow drawn around it.
Press Volume Down twice to designate Recovery mode.
Press Power to restart into Recovery mode. You will see an image of an Android robot with a red exclamation mark.
While holding down Power, press Volume Up.
Use the volume keys to scroll to "wipe data/factory reset" and press Power to select it.
Scroll down to "Yes - erase all user data" and press Power to select it.
Note: If at any point during the above steps your phone becomes unresponsive, you can restart it by holding down the power button for several seconds.
Before you try anything else, try and leaving it plugged in for a while and then try turning it on. Or leave it plugged in to a computer then try turning it on.

Try this. I haven't had it happen to me, but I do have a friend who this exact same thing happened and he thought it was bricked. He left it plugged into AC over night, and in the morning it would turn back on.
First than nothing, thanks for reply, I appreciate your intentions to help me.
I will leave it charging all the night and while Im working too... I hope after that, the phone at least turn on.
I dont install the STOCK ROM because I dont have it in my internal memory and I was in my girlfriend house, the night of the 12/31/12, there is not much to do...

I bought it the 13/nov..
I received it 29/nov.
I ALWAYS use stock charger, only 1 time i try to charge it in my car, but it was less thant 5 minutes, I decided dont charge with the car because the energy variates when I accelerate...
After that, I use my phone quiet normal.
I had this problem with my nexus 7. I think my battery died all the way and it couldn't charge. The stick charger wasn't doing anything. But I plugged it into my computer for a few minutes and tried turning it on. Then when the loading screen appeared I ran it to it's stock charger and charged it to full. Your battery probably died. Try different combinations of ways to get it to take a charge. Just long enough to turn on then plug it into its charger. Though the overheating could have fried it

There have been many cases like these. I think you will get enough hits if you use the search button. I had it myself recently, though the solution seems not to be very solid.
The best way to get it to work is to try different cables/chargers (via PC/Wall Chargers etc) and let it charge for a half hour, and try to start it. If it doesn't start, try another combination. Rinse, repeat.
A stronger charger seems to work better most of the time (2A for example).
In the end I got it to work with the 2A charger of a colleague that he always carries with him. I am assuming that there is nothing wrong with your battery besides it being completely drained.
Im not really sure though. Is that what the flashing red light means?
Open the phone up, pop off the battery connection, put it back, then try to reboot (you can reboot with the cover off). I got the red light after my N4 crashed doing an Antutu test after OC'ing it to 1.9GHz (yeah...don't do that), and after "resetting" the battery, it booted up just fine.
I had ever occur this issue and tried any fix from internet, finally completely battery died, so just buy a new one of battery .
Your battery is discharged to a critical level (1-2%) and the phone performed a shutdown to save itself.
Connect your phone to the charger and press POWER + VOLUME DOWN, to enter recovery. Then reboot from recovery
I had the RED LIGHT flashing and this is how i fixed my problem. No need to buy a new battery
Ur phone can't boot up cuz there is not enough energy from ur battery, so just charge ur phone for a while then u can boot up ur phone again red light issue usually for low battery and the phone can't booting up
i doubt it if mine is power issue. I've charged for long periods several times, i've tried several things i could find on the internet, i used a working battery, still no show. light blinks for a while and goes off when plugged to electricity. I'm thinking this could be a different problem entirely

Rooted now frozen in Installing Screen. Cannot restart.

Few weeks ago I found wife's old NST (non-glowlight model) in working order and decided to root it. Rooted it, played around with it. Wasnt too impressed, so just threw some ebooks for my kid to read while on vacation. Left it on my desk for a few weeks as I got busy with work. Today I picked it up as my son's vacation is next week and it's frozen on the "Installing... A new software update is being installed This will take a few minutes" screen.

Few weeks ago I found wife's old NST (non-glowlight model) in working order and decided to root it. Rooted it, played around with it.

The real question is whether it is actually still on or off. What happens when you connect it to a PC via USB?

Only the green charging light goes on. I do not hear the little sound it should make when making a successful USB connection.

And I guess the drives don't mount successfully. Well, disconnecting the battery should certainly turn it off. If reconnecting makes it start spontaneously (should not), you could prepare a Nook Manager sdcard and insert it before reconnecting the battery. But this sort of sounds like the ability to boot is lost. Hmmm. I'll have to think about it.
unfortunately disconnecting the battery does not appear to do anything... screen continues to show that 'Installing... " screen. Hoping to get this thing figured out with someone's help

E-ink screens stay the same unless there is a new powered input so it could simply be off, having run the battery down completely during an update (maybe Wi-Fi was left on? That would run down the battery for sure). So if all of this happened during an OTA update, it could be really messed up
When my NST is off, plugging in the power pack turns it on. Initially the LED is green and then changes to orange as charging begins. I'm assuming nothing happens when you do the same. If the OS is scrambled from losing power during an update it may not be able to boot. You didn't say how you rooted. If you used Nook Manager you could try putting in that card and then connecting to the power pack, hoping for a boot from the SD card. If you got that far you could try a factory reset.
My power button is sometimes really cranky and a few times I've run through my entire stock of words that do not come from children's books trying to get the device to turn on. So you might try, but if it's really off the power pack should turn it on.

When I plug in the power cable the light just becomes green it never (not even for a split second) turns orange. Yes, I'm rooted using nook manager. I just suck my Nook Manager SD card in the nook but nothing happens. I'm not sure what you mean by using the power button, in my original post I mentioned I tried the power button with no luck. What do you mean by power pack?

Power pack = charger.
So if the Nook is actually off, attaching the charger with the NM card inserted should make it boot. Did you try the procedure in the link above?
Just tried the procedure of unplugging the battery, holding the white power button for 30 secs, then connecting battery and connecting to charger. There is a split second orange light and then green the first time i plug it in....subsequent plugging results in always green....the issue with the frozen screen on "Installing" remains. Tried the holding x 20 secs method to promt a restart....nothing.... what else can I do?

If the battery is actually "dead" (not impossible on these old devices), the NST will not start, even if plugged in. Do you have a voltmeter of some sort to check the battery? If it's actually charged, it should show a solid voltage. If not, that may be the issue. If the battery is actually charged then there's a pretty serious issue that can't be fixed without access to the OS by ADB, or the ability to boot from the SD card. Beyond my "pay grade", at any rate, I'm sorry to say. There are batteries available online but the price may not make sense.
I don't think it's a battery issue. I had another NST with a good battery but a bad screen (lines all across screen) . I fully charged it using the bad screen reader and used the battery from it for the frozen nook... no luck.. oh well... I guess this is a paperweight now... thanks for your help everyone.
