Motorola XT 720 Start up problems

Why won't my XT720 start up?
When it is connected to my charger, the four action keys light up. Despite leaving it to charge overnight, it appears that the battery isn't charging. The phone won't start while it is charging, neither when connected to the mains or to my car power supply.
I bought a new battery without any improvement.
When I access the bootloader screen it says there is too little power in the battery to program the phone.
The phone is not recognised by my computer when connected.
The phone is running Froyo 2.2. with Dexter rom.
I would be very grateful for any suggestions......apart from binning the phone!
Thanks!

I think the phone likes to selfboot with too little charge. See if you can shut it down cleanly so it won't autoboot. It's annoying but you may have to watch it very carefully to catch it when it's trying to boot because it will drain itself back to death very quickly.

Hi Oakham, do you have any update to your case? I have the same problem now.
Yesterday, I noticed the battery bar went down to orange region (about 30%?). I plugged it to the wall for about an hour (the charging symbol showed up). Later I found out that the battery bar did not move (still stuck at orange region). Later the night, I tried to charge again (the bar was red at about 15% or less). The charging symbol showed up. Later I checked, the battery bar did not improve but declined. The phone eventually went out of battery and turned itself off.
I tried to continue to charge using both the wall outlet and PC USB. No luck. I could not even power up the phone now. Did you manage to resolve your case? Anyone got the same problem and found the solution?
I thought about buying a new battery to try, but then I saw your post, so I hesitated.
Thanks.

I've had this problem. Watching the phone closely while charging and pulling the battery whenever it starts to boot works. After about the fourth time doing this I got a battery charger from amazon for ~$5 because it's gently loving annoying.

Thanks for your advice.
So when you first bumped into this problem, how did you get it back to boot up?
I followed your advice to watch it while it's charging. When I saw the motorola logo showed up, I pulled the battery. Then I plugged it back and let it charged for some more time. Then I tried to power up the phone. The motorola logo came on and then the big battery symbol came on saying it's 100% full (but i knew it's not). Later, those 4 soft touch button lid on. This cycle repeated. And I'm clueless.
Please let me know the steps you took to recover your phone.
Thanks.

Once you get into the system use 'power off' from the menu. It won't autoboot then and you can leave it in the wall overnight. I think. A voodoo doll may work, too. It can be really frustrating, but I've been able to get out of it every time so far. Like I said, I got sick of this game and found a battery charger for pretty cheap.

Try deleting batterystats.bin and doing what M said.. can you get to open recovery and charge from there?

I also had the 'M' logo screen, stuck on-screen when the charger was connected. There is a post which suggests, for this, 'Pull battery.2) Insert battery and hit power button;3) As soon as you hit the power button, hold the volume up button down until the unboxing logo comes up.'
As my phone is still under warranty, I sent it back to see if there is a physical problem. I'll try the above suggested solution when my phone comes back from 'Motorola', whether or not it is repaired by them! I've also bought a battery charger for the phone's BP6X battery from e-Bay (£9.50, including another battery.)At least I will then know that a battery is fully charged before I try fixes.
Thanks for the other posts/replies!

In my experience OR drains faster than it can charge.

Damn!
I had about the same. Battery got drained down from 80% to 5%. Then the screen for "please plug in for charging" appeared. Some moments later the phone went dark and now I can't get it to work again. It doesn't react on the power button. Even when plugged in the charging-symbol doesn't appear. I can't turn it on. Sucks!
Any ideas?

My phone has been repaired by Motorola, under warranty, and returned after four days. Accompanying report is brief: 'Software update and screening'. Seems to be working fine.......just like a brand new phone!

This morning i find myself in the same situation. My phone have the soft keys iluminated but it didint work.OMG... what happend durring the night.So i tried to boot the phone but nothing happend,and after reading tje post on the problem i have tried to remove the battery and put`it back, tryed anothe reboot, and holdind the buttons power+vol up. Nothing worked. But when i have tried the combination power + vol up + cammera shutter and plugged the cable. at first nothing happend. but after i have relesed the buttons the logo apeared and started charging. after that i powerd on my phone normaly

My phone does that everytime it charging and I remove the plug when it's in sleep mode. I have to remove the battery and it's power on normally.

[Q] Completely unresponsive Xoom

I've got a 4G Xoom, that I bought new about 13 months ago. It's been great to me so far. I had it rooted and was running CM 9 on it and had been doing so for about a month without any issues.
Yesterday, it was plugged into the charger and I happen to glance at it and it was doing some strange things with the screen, flashing on/off, black lines on part of the screen. I powered it off and left it alone for an hour or so.
Since then, it's been completely unresponsive. I've tried Vol Up+Power button countless times without it working. The charge light (white) came on briefly while plugged in, but then went off, never to return. The only reaction I can get is that after holding Vol up+Power causes an orange light next to the front camera to blink twice. That's it.
Any suggestions? Is it completly dead?

Given that it's sealed, how is this done? I hadn't even considered cracking the case.

You may not need to remove the battery as several people have reported success with just slipping some paper between the contacts for 30+ seconds. You will need to open it up though and here's a post with info and pictures to guide you through that: http://forum.xda-developers.com/showthread.php?t=1578365
On edit: here's another thread with good info for you http://forum.xda-developers.com/showthread.php?t=1528706&page=3
Good luck.

Well, I did the paper under the battery terminals for 15 minutes and still no joy.
One item of note is that when I plug the charger in, I'm not getting a white (or green) light. At least not much of the time. Occasionally, I can wiggle the plug a bit and it will light up, but I'm not getting to green at all.
I can put a multimeter on the battery leads, does anyone know how many volts/amps I should be reading?

Are we sure that its not just a crap connection with the charging plug. It is a wimpy little pin and my Xoom needs me to do a rain dance to get it to charge. I have to plug it in, wait a few seconds and then the white light comes on , but only if the wire is flipped back over the top of the screen. Another thought is I use Tiamat ics and there is an option to have the light on or off during charge and I think it is set to off as default, maybe you didn't set that up. I would bet its something stupid and you just need to keep playing with the wire and see if you can get it on. Good luck.

[Q] MotoG dead after, can't boot.

Hello,
first of all, I've read every other guide on the internet with the same problem, I haven't found a fix yet.
My problem is a little bit different then others.
A couple of days ago my phone got really hot, so I decided to stop use it so it can cool a bit. It still had like 80% battery remaining. After it was cooled down a bit it wasn't powered on anymore and I was unable to boot it up, it was just dead. I placed it in the fridge for about half an hour, after that it was working fine again.
Now I have the problem that it won't power on again. If I plug it into the wall (original charger) There is just a white LED on the front, which means the phone is too low to turn the screen on, After 2 minutes or so the white LED disappers, but the screen is not turning on. If I plug it off and on again the white LED is back on.
When the LED is gone i tried pressing some buttons according to some guides in the internet. The only result was, when I pressed the power down and the power button while the white LED is off, it just comes back on after exactly 2 minutes.
I also tried 3 different batteries, 2 of them are original motorola batteries for the MotoG, the other one a cheap ebay one.
Is there any chance I can bring it back to live? Or at least get my data recovered?
Greetings,
Lukas

Moto G totally dead

Well, title says it all. My girlfriend's Moto G just went totally dead one day. I took it apart and measured that the battery voltage was very low. I also tried to charge the phone but all that it did is blinking white LED if Power button is pressed.
So, i went to eBay and purchased a new battery which arrived today. Popped it into Moto G aaand.. still no life. Even the white LED did flash no more Tried almost every single trick that I have found, still no luck, however few hours of charging with my G3 charger bring the white LED back to life. Now if I press Power button for a few seconds, white LED flashes quickly 2 times and then it goes away and nothing on screen. If I just let it charge without touching anything, I can see white LED flashing sometimes. Gonna leave it charging overnight and see if that brings it back to life. Any tricks what else I can do with this phone or should I just toss it away?

Can you enter fastboot mode, if you can that might indicate a sign of life.

Can't enter fastboot either Tried to press Vol - and Power, white LED flashed only one time but still no luck :/ Maybe the mobo is bad?

What you have done to it

Just standard use, but one night it just died. It did not wake with overnight charging. It is now sitting on my desk without charger, gonna try it in the evening when i go home. If it does not wake, i think it really is dead

Try looking up the led codes from Motorola's site or something. That might help if there are any. Seems to me that you have some hardware damage. But I might be wrong.

Try keeping it on charger for a few hours, then with charger connected, press power and keep it pressed for like 2 straight minutes. That should at least wake the device. If it doesn't work, I'm afraid it is busted :/

Tried that too, even pressed Power button over 2 minutes but all it does is white LED flashing randomly. Without charger it does absolutely nothing. I think the motherboard is busted

Seems like hardware damage to me too, use it for parts or sell it I guess.

why don't you take it to service center
it will be your best bet if engineer have a look whats the issue. just a get a approx cost. they will let you know. :good:

Won't power on

My myTouch worked for a really long time, even while overclocked. Today, when I was playing a game (Minecraft) it gets much hotter than normal. So I place it on my fan, just a floor fan, to let it cool down. Once it's cooled down, I resume my game. Out of nowhere, it just freezes and shuts off, then restarts, then turns off again once the BIOS splash goes away. It doesn't power on until I press the power button, then it only runs the BIOS splash and shuts off again. I try again, and it powers on to the boot screen, and then it shuts off again shortly after. I try it again, then just BIOS. And yet again, then a successful boot after letting it charge for about 10 minutes. I take a shower and when I come out it works fine, but 10 seconds into use, while I pressed the Bluetooth notification drawer widget button, it freezes and shuts off. From here on, it won't power on at all. I plug it into computer, nothing. All that works is the dim red LED on the trackpad. I press the power button, trackpad light turns on for a few seconds, then off. I press again, turns on for a second then off. When I hold the power button, the light is on and blinks every 10 seconds. No key combos work. Charge light does not come on when plugged in to either computer or wall charger. Any fix for this?

Not a fun situation, very possible your emmc is fried but there is a chance its just the battery. Let it charge overnight and if possible test a new battery
But there is a high likelihood you're going to need a new logicboard
If you're after a new device I do have a few oneplus one invites left...
Best of luck!

I have a very similar problem, i recently came across the mytouch 4g slide in the closet and remembered that it died due to charging overnight, 2-3 years ago lol, well the phone still does what it did after it died, no vibrations screen etc, the only sign of life is the two red lights one at the top left of the screen and the trackpad, could this be just the battery that got fried that night? Should of gotten this fixed those years ago but just got a new phone instead.

Possible but could also be a sign of a bad logic board

I have an extra one if any of you want it, not selling it, I can just mail it to ya, PM me about it, whatever. It's got moderate chips and dents, but works fine except sometimes the soft keys don't always work and you have to restart the phone. It has the latest CWM recovery and the latest 4.4.4 ION ROM. No SD card ships, but baseband and all wireless works, but uh, it's SIM locked and S is still ON. Bootloader is unlocked. I'll give you an extra screen and an extra battery, too.
I fixed the one I posted this thread about after I realized I could buy a new motherboard directly from HTC with a few hidden strings pulled (I'm just that special) and before that I ordered the one I'm talking about now that I'm trying to get rid of on Amazon.
So, yeah. best way to fix one is to get a new motherboard, the one from HTC's old stock warehouse that I got took a week or so to ship, and I cracked the casing opening it and almost ripped a connector ribbon, and I also think that this phone surpasses the G1 as the most mechanically intricate device I've disassembled. I've done a few, but man, this blew the top.
