[Q] Broken mainboard suspicion on xt910 - Motorola Droid RAZR

Hello,
I hope it's OK to post HW related questions on this forum.
I got an xt910 from a coworker which has a broken screen.
It does not make any bootup sound and is not showing internal memory when connected to a computer, only a white LED is glowing.
I suspect a broken mainboard, as the screen cracked when coworkers' daughter jumped on his lap. It did work for a while but then it died.
Can you confirm or overrule my suspicion?

Been hasty
I was too hasty to post the question.
After I posted this thread the phone vibrated and the buttons lighted up. It did not show any internal memory tho. After I disconnected and the cable the buttons stopped glowing. After I reconnected the cable, the white LED startind to glow again. It might be a case of dying battery.

Thanks for your input!
I charged the phone for an hour or so via USB cable from the computer as I don't have the Motorola's wallcharger. Instead of white blinking light it shows a green one every 3 seconds. The buttons light up for a while but no connection to internal memory.
OK, so the mainboard works!
But to retrieve the numbers and data a working screen is needed. I called a service and around here it costs 15 € to access the data.

I think the digitizer is gone. Rest would be good.
You can take backup from pc itself by building recovery. I have read somewhere but i don't know the steps..

Razr Max won't charge or start up.

My Droid Razr Maxx completely died and now won't charge or turn on,there also is a white led light located left top of phone that's on when charger is plug in. My razr was not rooted or unlock 2.3.5.Please help,any advice will be rewarded thru PayPal. I'm trying to avoid replacing it with a refurbished phone,my phone has had a screen protector and been in a case since day one. Thanks for any and all help,sorry if this issue has been address.

Hold down screen lock button and down volume button for about 20 seconds and then the light should turn off. It should turn on, the phone, or you can put it on by hold the screen lock button.
do this while plugged into the wall, not usb
I wish it was that easy,I try holding power nd volume up then down and vice versa to no avail. I also have my phone plug into my wall charger. If anyone helps me get my phone turn on and charge I will donate to your PayPal asap.

Try a different USB cable and plug it into a USB port on the computer. This isolates the USB and the Moto charger to make sure they're not the cause.

Try holding both vol up and down together, then hold the power button, so 3 buttons are pressed at the same time, and hope something happens.
Any of this end up working for ya?

The white led means you're out of battery and conected but not charging. This happend due a rom flash error.
You'll need a Factory Cable to put a new firmware on it and then charge after that

If you got it from Verizon you still have manufacturer warranty, return it.
Had this problem myself, white light, couldn't charge, tried every trick there was. With stock cable, this is how I got my phone to charge:

Phone so sharp, I sliced myself.
I got this many times when trying to charge my phone via USB on my laptop.
I held vol up/down and the power button like Nikorasu recommended and the light disappeared and the phone gave me the "DUAL CORE TECHNOLOGY" screen, looked as if it was going to turn on and then the light turned back on and the screen went back to black.
*UPDATE*
I left the phone plugged in for a long time and I came back to see the white light off and the phone *on* and charging. How nice.

Plugging it into the usb port of a laptop is not enough. I've had cases where I plug my phone to the computer to transfer files and the battery level actually dropped.
Use the Razr charger.
Thanks!!!
I didn't know this handy reset feature, until my razr froze and turned into a paperweight for the rest of the evening.
(thought maybe I wrecked it with some new 'root only' apps)
The reset worked great and runs fine.
Only get Motorola logo after 3 hours of charging
Hi,
I'm new to Droid Razr's and I have a Maxx that is doing this. I tried the (volume +/-, then plug in) option and phone has stayed on Motorola screen for a few hours. No go on the charging screen. Not sure if the Maxx I got has other issues. I've used a motorola usb/wall adapter and a Motorola MicroUSB from a Droid X dock that is supposed to be a faster charger.
Any ideas?
Thanks,
Victor
My Maxx is in a similar situation. When I plug it in the Motorola dual core screen comes on and then it goes to the safe system screen where it asks you to touch menu to enter safestrap or search to skip. After touching either button the screen just goes black. Sometimes when I plug it in it will show a red battery at 0% then immediately jump to 5% and then after a moment or two it shows a blue battery at 100% but still won't turn on... When I plug it into my laptop though the screen stays black and the white led is on. Do I need a factory cable to fix this or what? Thanks in advance for any help.

Exactly! ...I have this phone and the EXACT same charge problem, white light, phone dead has happened multiple times. My galaxy s3 charger won't fix it....no other usb charger works. Every time I must use all oem chargers and I solve my problem. Why? I believe it is because the razr maxx's larger battery uses a slightly higher charge voltage. (5.1v vs. 4.5 v to be exact) ...look at the charger specs. After leaving on the oem charger for some time, it never fails to boot.

[Q] HTC one Multipe issues (rooted) HELP!

Ok, I rooted my HTC about a month ago. All was working fine. I did notice though in visual voicemail the settings menu (3 dots at bottom) were not there like they are on my wife's non rooted HTC One. Today with the gmail update I also noticed in gmail the settings menu 3 dots on the top right are not there.
Now the big problem. I held down the power button to reboot phone to see if that would fix issues and now phone wont come back on! Also when I plug in charger no indication it's charging, no red light.
FYI when plugging in to my PC while no red indicator sync manager does come up so it is being recognized.

yea when battery completely dies there is no red light at least thats what other users have reported. but after leaving it plugged in to the wall not usb for a while they were able to get it back on in most cases

keep trying the button combo in a well lit room and make sure your fingers arent covering the light sensor
let me know if you get it or not also just holding power should work too
OP mine did the same thing just a few minutes ago. While ringing a call it just went black, and like yours, shows no signs of charging and is completely unresponsive.
I tried waking it under a bright light and nothing.

Droid Razr won't charge or turn on

I plugged in my razr before I went to bed. I've been using a HTC plug and cable for the last few months no problems. Woke up this morning and battery was at 5% and then the phone died completely soon after. I plugged it in using my original motorola plug and cable. The dual core screen came up and then the battery level said 0% and it looked like it was charging. It died again after about half an hour. Now nothing will get the phone going. I also tried the hard reset (Power and volume down). The phone is unrooted and hadn't been updated to Jellybean yet.
Any ideas what I can try?

Try using the correct charger and charge it for about an hour, thats the first thing I would try. How long is the htc cable you're using because the longer the cable the slower the charge.
I have tried multiple different chargers with no joy. I think the problem is with the connection. When I plug a charger in the white charging light flashes briefly for a second. I checked the connection for dust and it looks clear?
Try Booting into bp tool or hw diag (hold vol up and vol down then press power should see black screen with white text vol down moves cursor vol IP selects) the phone should charge if left in one of these modes (if you can even make it this far without the bat dying that is). if that don't work could try disassembling then charging the battery directly (never tried this its only an idea try at you own risk)

Yes I have and no button combination produces as much as a glimmer. I've had the back off and checked the battery for charge, it shows 4.3 volts so it's not that. Something has failed catastrophically I fear.
Check the battery's cable that connects to your phone.If that cable was broke,you can just see the battery level but without charging it.

I've read around this a little now and have invested £3 in a Motorola Factory Cable of fleabay which hopefully will resolve the issue. Due to be delivered next week so I'll keep you posted......
Well got the factory cable and tried it holding the vol down button. Nothing. Took the back off the phone and checked the voltage of the battery 2.75v. Removed the battery and tried the factory cable with vol down. Still nothing. Reinstalled battery and left charging off a pc overnight, this morning it had risen to 2.83v. Starting to think that this phone has had it
Cut the end off a micro usb cable, exposed the wires and connected the red and black to the battery terminals then plugged it into the moto wall wart. Left it until fully charged....volt meter read 5.1v, the output of the charger. Disconnected and checked charge, 4.2v out of the battery.
still dead. Nothing. No red moto screen, no recovery nothing. Something else must be amiss. All I get is a brief white led flash when I plug in the standard charger cable.
anyone have any ideas where to go from here other than the skip?!
Just resurrecting this thread in the hope someone has found a solution....
I still have a brick which is unresponsive to two factory cables plugged into my PC with and without the battery in.
Trouble is I've got pictures on there I'd like to recover if possible which causes me to persist with this troublesome device!

I access the boot menu by holding both vol up and down, and pressing the power button (hold for ~2 seconds, and release the power button, while still holding vol +/-. Volume down will only send you to APFastboot. Check out the post, I encountered the same problem. The final method I tried was the winner. Good luck, and let me know if you have any questions.
Thanks for that, I'll certainly give it ago when I get a free hour one evening this week. I am concerned though that the factory cable doesn't work, I was under the impression that the phone should at least respond to its connection in some way - it doesn't even when vol-is depressed when connecting to pc.
The only response I get from the phone is a brief flash of the white led as the usb cable (factory or charging) is connected to it.
That indicates that there isn't any power management remaining on the phone, and the battery is pretty weak. You'll need to get the battery charged up manually. After you flash with the last method I used, you should be able to reconnect the battery and charge the phone all the way up before booting. Sounds like you're having the exact same problem I did.

Really , Really wanted this to work but it doesn't look promising.
Made the USB charge cable as described (white and black twisted together to -ve, red on its own to +ve). Battery removed from phone, usb on charge cable connected to PC.
5 Volts found at the battery connection terminals. Original Moto Data cable connected to phone then PC. White LED flashed on for slightly longer than before then off. No response from phone - nothing on the screen or vibration with or without any combination of Vol- and vol+.
Battery refitted and charge lead attached to terminals as above to charge from PC. Now reading 4V across the terminals charge lead plugged in, 3.84V cable unplugged so presumed charged.
Still no response other than the brief white LED from the phone with either the Data or Factory cables and Vol-(or any other Vol configurations).
Any ideas???
I assume you tried pressing and holding all the buttons, for five or ten seconds, or even a little longer, to try a full reboot. Beyond that, I wish I could help more. I'm slap out of ideas. This was the last step for me (as the solution usually is). The main board might have had it, though I don't have a clue why.

I'm thinking dead mobo too. When it died it did so overnight without provocation - no flashing or tinkering, it was left on the kitchen sideboard and found dead in the morning. oh well I've tried. many thanks for your help:good:
Glad to try and help. I guess it's time to move on to the next device! Let us know if the phone sporadically decides to work, or you figure out a solution!

I am not sure if you already watched this video, its for droid razr maxx, charging a dead battery and works perfectly for droid razr too.
My droid razr was exactly in same condition, white light and no charging, did not power up, completely dead.
I popped open the back case, connected the modified usb cable wires to the positive (Red wire) and negative (black wire) ends of the battery and let it charge (stay connected) for one hour. Then i pressed vol up+ vol down + power button. And my phone switched on.
If only your battery is dead, this should work.

[Q] My ZU wont switch on. Red LED

This morning, my Z ultra died on me. It wont start, no vibration, no use pressing vol + power buttons and the red switch. I was neither rooted or bootloader unlocked.
When I tried to connect it to my laptop (Windows 7), its shows as a USB device. The red LED flashes up, the computer finds it and then lets go of it again. Again in a few minutes, the red LED goes up , the computer makes the connection sound and then the red LED goes off again. This cycle goes on and on.
I cannot use SEUS, Flash, Fastboot or do anything. I have checked various forums and apparently I have not hard bricked the phone as the LED still works and the computer recognizes the problem. But no one has given any concrete solution.
When I connect it to the charger which came with the phone, the red LED pops up and then goes off again. I dont know if its charging. HOWEVER, I have used another Chinese Travel Charger, and then the red LED stays solid as if its charging. I dont know what it means.
Please help. I spent a lot behind this phone. I dont want to be left with a brick
It's not an issue if it's completely stock is it? You have your warranty, but i understand that i sucks to have it shipped in for repairs for god knows how long. I had a similar issue some time ago, but i'm bootloader unlocked and what not, so that was pretty easy to fix. You're completely stock though, so it's a little harder to do anything.
What happens if you hold VOL UP when you connect it to your computer? Does a blue LED light up? If yes, does it stay on, or does it disappear? What happens if you hold VOL DOWN when you connect it to your computer? Do you get a blinking LED and then nothing? That's normal, and it's going into Flashmode. If you can get it to stay in Flashmode you'll be able to re-flash a ROM in Flashtool. But be 100% sure to have enough battery, or else you'll be in danger of hard bricking it.
So..
- Plug the wall charger in and charge it for a couple of hours (2-3 hours)
- Try to kick it into Fastboot (VOL UP when you connect it to your computer). Look for blue LED.
- Try to kick it into Flashmode (VOL DOWN when you connect it yo your computer). No LED.
Hi LordManhattan. I dont have any warranty as I brought it from a local reseller .
Whether I press Vol UP or vom DOWN when I connect to the laptop, a red LED pops up, there is a connection sound and after that the red LED goes off and and there is a disconnection sound.
If I leave the phone connected with the computer, the phone gets connected after 2/3 minutes, there is a connection sound and then there is a disconnection sound again . Any clue what I can do :crying::crying:

just a small note or two:
Flashmode the LED should go orange, then blue then off within about 1second then it is in Flashmode
To get into either of these modes the phone has to be powered fully OFF, press the red reset button before charging to make sure, then again just before the above steps.
It sort of sounds like a corrupted loader

Have a good read of this? http://forum.xda-developers.com/showthread.php?t=1849170
It would suggest that the battery is flat. Let it charge in the wall plug for a few hours and see what happens
I have let the phone to charge overnight with the charger that came with the phone. As I said before, with that charger, the red LED would turn on and then go off again. I will hopefully try the Chinese travel charger tonight with which the red LED remains solid.
The funny thing is , the phone had about 80% charge when it died. This is so weird :'(

Have you tried the reset button under the microsd flap? Press and hold for 3 secs.
I did read another user had an issue where the screen blanked for around a day, he left it plugged in and came back to it about 6 hours later and it was fine again.

It's a battery issue most probably. I guess it doesn't show anything. Is your battery removable?
I still have not opened my phone. I am looking at all the other options first. If everything else fails, I guess I will have to open my phone

Warranty exists with Sony for first year, no matter where it's bought, very true.

+1 contact your local sony, i had a similar problem, no fastboot/flashmode. locked bl/not rooted and my led only flashed red and occasionally solid red then nothing. plugging it into computer continuously played the disconnecting sound.
most likely hardbricked.
i also purchased my xzu from a local BST but as long as you have your imei, contact sony and theyll tell you if you have warranty. they required me to send in proof of purchase as well but like most say "play stupid" ( i said i received it as a gift and they said it was fine)
i got a brand new XZU after a week and a half sending it in.

Thank you! One or two years ago my Z Ultra's screen cracked and I got a new phone. Decided to use it again, purchased a new screen and replaced it myself today. When I tried to move to AOSP (had root, bootloader unlocked, backup of TA partition), the phone bricked. No SONY logo, nothing. Did what you said above, Xperia Companion recognized the phone in flashmode and is now downloading the newest stock rom. I was so afraid of a hard brick, that living with latest stock without root doesn't seen so bad now hahaha
Hey Friends, I have exactly the same issue. The red led just flashes up for a couple of seconds and this cycle continues. My battery was a bit swollen up and the back glass cover opened up a bit. Still battery was working fine. Two days ago I tried nougat aosp on it and after leaving it idle for 2 hours, it was bricked. I can enter into flashmode and flashed stock LP as well as KK but it does not boots up. Is it definitely battery's problem? If yes, where can I buy original or near original battery for it?

The battery is dangerous and should be removed. Be careful because the battery can burst into flames if the bloated cell get punctured.
Use tools with caution and take your time.
Lipo cells expands as a first safety trigger. Instead of going strait to venting or venting and burst into flames.
Its a safety feature if they are charged with too high current or if the cell is drained below its 2,22 volts and is brought back to life with a normal charger that puts normal current on the cell. Then even 400mA in this scenario is way too much current to start charging a drained cell with.
But the battery should not be the issue that your phone is not booting. How did you flash stock rom? With Flashtool?

[Q] Issue with Sony Z2 (red light notification blinking 3 times)

Hello,
Can somebody assist me with a problem I have with a friend's Sony Z2. I'm not very familiar with this phone and I have an issue with one.
It had the screen replaced because it was broken and before putting the last screw I turned it on to see if it works. I needed to put on charge because the battery was 1%. It worked perfectlyand then I disconnected it from charge, removed the battery flex cable to mount the phone back and when I finished it, I tried to turn on, but unsuccesfully.
All it does now is, every time I push the power button, the notification light is blinking red 3 times. Nothing more. If I keep Power and volume up is doing nothing, unless I put it on charge (on charge and power+volume up is vibrate 3 times too). I have nothing on screen. Reset button (the one inside SIM slot) makes the phone vibrate 3 times. The pc detects the phone 1-3 seconds and then nothing, I don't see it in my device management. I tried with another battery and same issues.
Any idea how to fix it ?
Thank you.

Thanks for the answer mate.
It was 2 nights on charge and still nothing. Also the notification light remains red while charging ? It shouldn't turn green when the charge is complete
Did you check flex?

The flex comes with the battery. Since I tried a new battery, I guess isn't the flex cable.
Sadly that's all I can say
