MDA will not turn on!

I know i'm being a pain but now my MDA will not turn on, i was following the CID unlokcing thread, downgraded to Wizard Love ROM which went fine, the proceded to flash buttons 1.5 ROM and as usual it hung, went to do a reset to bootloader screen to reflash but it never got there , it doesn't turn on, battery was charged earlier can't have run out already can it?
Any ideas? i've tried to find info to help but can't seam to find any.

I know you've posted elsewhere, but it really helps if you tell us your phone model, if its G3/G4, what the IPL/SPL was before the problem started, etc...
Unfortunately, with the little info you've provided, I can't say for sure what has happened, but on first blush that sure sounds like a brick.
I would suggest you take the battery out of the phone, then press and hold the power button for 10 secs (this should discharge any remaining power) and leave the battery out for 30 minutes (might be excessive, but lets play safe). Don't plug it in and don't do anything else with the phone.
Now, after 30 mins pass, then put the battery back in and plug it into the wall (not your PC, but the wall). Again, don't do anything else. Don't press the power button or anything. If the phone acts like its trying to turn on, then turn it off. Let it sit plugged in to the wall for about 10 minutes. The charge light may or may not come on. If it does come on, then just leave it. If it doesn't come on, then try turning the phone on. If it comes on, then leave it on for 30 mins then turn it off to let it complete the charge.
If none of this works, I suspect you either have a dead battery, or your phone is a brick.

right phone is a G3 is was running the IPL/SPL of whatever buttons ROM has, as i said it hung like it's done a couple of times before when i tried buttons ROM but the other times i've just got into the boot loader menu and re-flashed and away i go, i'll try the battery thing in a fue mins, the battery was showing no signs of going bad was holding charge fine do the batteries just go like that? if it doesn't turn on would i be able to send it back to t-mobile as it's still in warrenty could they fined out it has a custom rom on it i.e is there away to say look at the rom on another peace of equipment to see if original or not, don't know if that makes sence.
grrrrrrrrrrrrrrrr was going to stay with the wisard love rom i kinda liked it, wish i had now
thanks for the info

Just out of curiosity, but why did you go back to the Button ROM? Once you CID Unlocked, you are done with that process. You can flash official 2.x and custom roms to your heart's content and not have to go back to the Button ROM again. Only time you ahve to do CID unlock again is if you do go back to 1.xx IPL/SPL for some reason.
Good luck, I hope that works for you. As for warranty, but doing any custom stuff you void your warranty, but if the phone won't come on at all, then I don't see how they will know (not like they are going to pop a chip out and look to see what's on it).
And no, I wouldn't think the battery would just completely die under normal use. You usually start noticing it can't hold a charge first.
Could be this is a hardware issue, but really hard to say.

i wanted to go back to the button ROM so i could CID unlock my phone, i was having trouble with buttons rom hanging like it did this time and it was sugested that i downgrade to wizard love rom then to buttons rom. I know it voids my warrenty but as u say the phone won't come on at all, oh well i'm doing the battery thing now. think i'll get the battery charger to see if the battery needs charging you never know!

looks like i've bricked it lol

Sounds like it could be the battery, in some cases it will fully discharge (e.g. when shortcircuited) and then can no longer be charged in any regular way. You can try this:

Broken Power Button

My power button has been acting funky lately, i thought it was just a software issue until i switched my battery today and realized it was hardware. now i cant turn on the phone.
Is there anyway to power on the phone via fastboot or some usb command? i need to get some files off the device before the device swap but i dont know how to turn it on without the power button =[
any ideas?

One of the bloggers on Droiddog.com had the EXACT same question. Yes it's possible... read her method here:
http://www.droiddog.com/android-blog/2010/06/nexus-one-power-button-failure/
Basically:
Plug the phone in– USB or AC works fine.
Wait until the charging light comes on.
Remove the battery, while leaving the phone plugged in.
Replace the battery.
After about 3-4 times, the phone should boot.

i need to know if i can turn it on via usb command, ive already called in for the device swap.

if you take it out and wait till right after the charging light goes off then put it back in it seems to start up a couple seconds later!

Glad you got it up and running. Sorry I misunderstood the question.

NAND Phone-Off Charge Issue - *WORKAROUND*

I've been having this problem since the first installation of MAGLDR; The "Orange LED" bug, as most of us know, prevents the phone from charging while the phone is off, and the LED remains orange even AFTER the phone is unplugged. I've found a few circumstances where this will occur:
1. Powering down the phone with USB plugged in causes this issue with most builds
2. Same as #1 but when doing a reboot
3. Phone dies, then plugging USB will bring about the "orange LED" bug
I've found a workaround for these as I'm sure MANY of you have already, but I wanted to post a thread just for people who haven't found an answer yet. The following list corresponds to the items above:
1. Unplug USB before selecting "Power off" on your device
2. " " " " "
3. Kinda tricky.. a) if phone is COMPLETELY dead, pull the battery, plug USB, THEN replace battery, and b) If phone has battery and is OFF, power on phone, wait until "GO! GO! GO!" screen disappears, and then plug in USB.
I think the problem comes about when finishing the installation of your ROM via MAGLDR, OR it could be a bug within MAGLDR itself. It could quite possibly be the kernels, as JDMS' UltimateDroid ROM did NOT cause the orange LED when a REBOOT was performed...
Well either way, I hope this helps some people avoid this problem and gives the dev's something to work on.. Not that their work goes unappreciated

Or do like me. Leave the phone on, put it in flightmode and charge it.

How would this help if phone is completely dead? Seriously, this could be useful. Can someone try this and confirm?

I'm afraid to answer here as the OP might get upset, or tell me to start my own new thread.
Anyway. As I like to help people I will answer your question.
I bought a new battery for my HD2, and it did not have enought power to power on the phone (running NAND).
Not sure if this fixed the charging problem, but I removed the battery for +/- 30 seconds, reinserted the "dead" battery, plugged in the charger.
After some time (seconds) the orange battery came on, and the battery was beeing charged.
I left the phone charging for some time (expecting the light to go green when done), but it never did (NANDproblem?)
So after 1/2 day of charging, I disconnected the charger, and guess what.. the oragne light was still on.
Again I removed the battery, reinserted it again, and powerd on the phone.
The battery was fully charged, and I'm now enjoying 2 to 3 days of phone use before needing to charge it again.
Now.. I'm not 100% sure about 1st connecting the charger, and reinsering the battery, or 1st reinsering the battery and than connecting it to the charger.

I'm having charging issues but in a different way.
when i plug the charger to the phone while the screen is off, the LED does not light until I i press the red button (actually any button) to wake up the screen.
Is anybody having a similar issue?

This is not a problem for me too. The real problem is with whatsapp
when ever someone sends me a message on whatsapp while the screen is off, i dont receive it until i press the power button to unlock the screen. So i thought this might have anything to do with the charge issue.

I have no problem with this bug,he it is on the charger,so why turn it off is my question.....i just turn the sound off lol.

[Q] HD2 crushed suddenly (stuck in aMAGLDR v1.13 boot screen)

Hi, I have a problem with my HTC Leo. I have been succesfully using NAND Android (PacMan HD2) for over a year and now it suddenly crashed. When I try to boot it, it vibrates once on HTC screen (a white one) and than changes to aMAGLDR screen and vibrates 7 times. It does not show the menu, only labels at the top of the screen (aMAGLDR V1.13, build date and author).
Is there any possibility to fix it? The most important thing for me is not to lose my data, specially messages...

install magldr again. I did it, didn't erased anything. but try with your own risk.
sorry for my funny English

Thanks for advice, but... it won't be so easy any longer Yesterday when the phone was stuck on aMAGLDR screen I was trying to put it into bootloader (holding volume down and pushing reset button) to give you some more info about my HD2 and it has turnd off and never on again!;( Now it's not even possible to turn it on, it does not 'recognize' a charger (green LED not 'turning on' when I plug in a charger)... Do you think my Leo is now only a crap of sheet?:/

Whoa- there, slow down, buddy! You don't even know what's wrong with the device, you can't just "advise" him to JTAG his device!?
As shanman said, check the battery pins, one or all were likely bent during a battery pull or something. If that's the case, it's not serious and does not require a jtag to fix. Simply straighten the pins and your device should start working again (If the battery still has charge).
If that didn't work, try another battery, or recharge the battery externally.

Battery pins look pretty nice, I also checked the phone with second battery... But the point is that it does not even react for plugging a charger (I heard that HD2 boots up when you plug the cable and then pull the battery in). And what more the phone had crashed while I was trying to put it into bootloader, without pulling the battery out...

Nexus 7 won't turn on

It seems there are already several threads about this seemingly common issue with this tablet, but I've tried the normal checks and still can't get any life out of my dad's nexus 7 whatsoever.
I've found several threads stating it's just a loose battery, but in this case it isn't. I've checked absolutely every single connection I can get to without removing the void if removed bits, and can't find anything suspect. However it still won't turn on, won't charge, etc. It's not a faulty charger or cable either, we've all got android in my immediate family and we can't get any life out of it with any lead or charger. It was simply working one day, it was turned off the way it always is once my dad had finished using it, and now it simply won't come back on again.
I also saw some people say to get it into bootloader mode by holding volume down and power straight after plugging it in, but that too does nothing whatsoever?
Does anyone know of anything else I can try, short of sending it back to Asus?

How long have you had it?
This sounds like something that should be addressed as a warranty situation, as anything else may be kludgy at best, and may fail again just after your warranty runs out.
I wouldn't really waste any more time.
JMnsHO.... :beer:

My dad has had it about half a year, maybe a little more. But he bought it from Comet, who no longer exist since they went under just after Christmas, so he can't return it to them now. Unless it'd just go straight to Asus instead.

I had exactly the same issue.......I fixed it by disconnecting the battery and reconnecting which by the sound of your post you have already tried.......you should be able to go straight to Asus for repair.......good luck....
Sent from my Evo 3D GSM using xda app-developers app

After probably 30 days it would need to go back to ASUS anyway.
As I'd said, I wouldn't waste more time fussing with it.
They'll take care of it and still preserve the balance of the warranty.
If you messed with it too much, you may find yourself with none at all, and on the hook for the cost of the repair.
Make the call.. :thumbup:

Well I've not done anything that shows I've been in there like I say, so any manufacturer warranty should still be intact. Same goes for the software too, not rooted, on the standard rom and kernel, etc.
I was just hoping I could fix it for my dad without having to send it off.

Not yet, but anything else would be more 'intrusive'.
How long have you been working on it?

Not long, only 10 minutes here or there to see if I could find something loose. I might check the voltage of it's battery to see if it's flat, and also check to see if any power is getting to the battery while charging. That'll help prove if the battery or it's control board is dead or not.

Just checked the battery over. It's a 3.7v battery according to the label, and my multimeter shows 3.7v, so the battery is fine with no loose connections. At the connector for the power button ribbon cable, I get the 1.8v that should trigger the tablet to power up when the power button is pressed, and the power button is good too, only showing continuity when pressed. Again, no loose connections. But the bloody thing still won't turn on.
Any more ideas?

When you say that you "tried all the normal checks", does that include all of the fixes listed in the sticky dedicated to this subject?

Yes, your thread is about a faulty or loose battery. As I've said, it's not a loose connection and I've now tested the battery too. Unless you can think of something that I've missed?

That sticky has all of the well-researched methods of addressing the collection of related issues (won't turn on/won't turn off/battery status). It is not only about a faulty or loose battery - there's much more.
Give it a read and let me know if there's a fix in there for you.

I have read it all, and unfortunately there's nothing in it for me.

If your able to get to bootloader maybe try to power off then let it charge for awhile then boot, or hold the power button for a good min

It won't turn on at all, so it can't get into the bootloader. Tried already.

I know you tried almost everything in the box, but when you plug it in the wall and press and hold the power button do you see the screen light up but still black?
If yes ( hopefully ) then continue holding power button then press VOL down til arrow pointing with START appears. Cycle through with VOL down til you see power off and select.
After it shuts down unplug from wall and replug and let it sit for a long awhile
If this didn't help at all sorry......good luck....warranty?

Nothing happens whatsoever mate, even while plugged into the charger. Tried the original charger, my s4 charger, my old HTC chargers, from the pc via USB, etc. None of them make any difference.
Got a feeling it might be the motherboard, as it has power. Can't be the display since I've tried getting a logcat from it after holding the power button for a while to make sure it would have turned on. ADB just kept saying "waiting for device" as if it wasn't plugged in, confirming it isn't even turning on.

Can anyone think of anything I've missed?

Can the pogo pins be used to charge? bit of a long shot and you`d need to buy/borrow a dock of some sort. Definitely sounds like a hardware failure issue.
