Micromax w900 hangs during start up - Windows Mobile Development and Hacking General

Hi guys,
I have been using this Micromax mobile for about 2-3 months now, without any issues, but lately it has started acting up.
Whenever I press the start button, the screen displays initial windows logo with blue background, and it gets stuck there. nothing happens after that.
I even tried restoring the factory settings using, the Volume down + camera + start button combination. It does display a green screen, saying to set the factory settings press the volume up key and to cancel any other key, when I press the volume up key, it again disaplays the windows logo and stays stuck on the same screen.
I am currently not and in India and cannot goto customer care.
Does any one has a solution for my problem ? please help. Even if I need to re-install the os, please share with me the details.
Thanks.

booting problem for O2 XDA IIs mini

I am having O2 XDA IIs mini and facing a problem that whenever i soft reset my phone it displays band of three colour Red Green and Blue on the screen and it do not boot.
when I press jointly communication button + recording button on the right side of the mobile and reset button holding other two it boots in a proper way
After booting the buttons on the mobile like up down send stop buttons stops working but when i press the messaging button and internet explorer button (Hardware Buttons) one by one the all the button starts working properly
please help me rectify the problem
I would suggest reflashing an official ROM back on there first and see if that fixes the problem. If you haven't ever falshed a new ROM on it you might also want to check and see if maybe theres some dirt or something keeping the camera button depressed. That would cause you to boot directly into the bootloader (the 3 colored screen), but since you get it to boot with the second method you try and it doesn't boot directly in to camera mode that probably isn't the cause.

XPERIA X2 won't enter bootloader help!!!

Hi, I am having problems getting my X2 into boot mode in order to update the firmware to MR1- I've followed the instructions on SE Update Service (press and hold volume down button and power button until white screen appears)
All that happens is the vibration feedback to indicate power on, then the phone loads up as normal with the logo in a black background???? anyone else come across this?
help me X2
hi all fri
i had one sony x2 ,but have some problem !can you tell me how to enter undate mode !and X2 chinese rom! thanks
do you press and HOLD both buttons till the desired screen appears? Should not release Power button before the screen emerges..
Yes I did, It's just loads up as normal, I have the xperia x1 so I'm not new to this devices, anyone experienced this before?
Are you sure that you are doing it exactly like this:
1. Remove and re-insert battery.
2. Press AND HOLD the volume down button.
3. Press AND HOLD the power button at the same time.
Hold the two buttons (and no other buttons) until logo on white background appears.
The order is important, first the volume down button - keep pressed, then the power button - keep both pressed.
The most important thing that many people miss is...
You must NOT have the USB cable plugged in when you do this. Only plug the phone in after the white screen appears.
This is not my first xperia as I still have the x1, so I do know what I'm doing, the phone boots up as normal (sony ericsson logo with the 'black' background) unlike the x1 with the tricolor screen. Is there anyother way to enter the bootloader or reset the whole ROM? someone please help as I can't update my phone and spony ericssonwon't do anything about it because it hasn't been officially released in the UK :S
i have the same issue tryed every thing (volume down + power =nothing. volume down + power +soft reset button= nothing. look in the registry found nothing relevant to bootloader )i think bootloder got messed up or something. is there a folder or something containing the bootloder

Exactly the same problem
same here, very frustrated, need my phone back to factory settings! any1 help please???
It's important that you normally turn off the phone before getting out the battery or it will reboot normally when the battery is inserted.
X2 DEAD
I also have the same problem as my device does not turn on nor k is functioning BOOTLOADER MODE.
only once beats vibrating k after the computer sees an unknown device.
I left my phone in few mobile services, nobody did any good to it - same problem still left. Last chance will be SE service.

To get back into factory-defaults, then use the Phone reset found under Settings->System. That will re-install everything.

[HELP]Screen turns white with black corners

Hi !
I bought a Nexus 4 for 10 bucks from a taxi driver knowing it has this problem . I searched the whole internet and barely found some info, most of the people who got this problem just force closed it and then it worked. But with this one, it happens everytime i turn it on.
You can see the problem in the video.
Also, if i let it boot, i can change the volume and i managed to turn on the flash, so the touch is working. And the screen does the same thing if i wake it, but it's not that bright..
Can anyone help me ?
I don't know if it has root or anything, if you can at least help me with a guide to flash it without knowing anything about the software or the settings in it, i'd be really thankful!

Hi
If you can go to stock recovery i.e press an hold volume down+power button until you see bootloader.
Then press volume down key until you see recovery. Press power button to select.
Then press an hold power button and press volume up key and release all keys.
Now you are in recovery.
You can do a factory wipe.
See if that solves the problem.
Good Luck

Fast fast try to return it before Trump wins . He will build the wall you know... Jk...
For my opinion LCD has to be changed. Due drop or in your pocked from high pressure i think its gone ...
Since as you said phone is working you can take pictures or receive calls but screen is always black.
Can you see its black color or screen isn't turning at all.

S7 Edge BSoD Extra Info. needed
Hi,
Phone: I have a Samsung Galaxy S7 Edge SM-G935FD
I was using my phone to send a txt (and at the same time I think I was receiving a text or call because the menu and back touch buttons were lit up) and all of a sudden the phone crashed as I tried to finish my text but the touch wasnt responding, then the backlight turned of like it does if the phone is not being used. But the strange thing was that the menu and back touch buttons stayed lit up (Solid).
I tried many methods to restart the phone:
Power button + volume down (FAILED)
Power button + volume up (FAILED)
Power button + volume down + Home (FAILED)
Power button + volume up + Home (FAILED)
So I thought I'll let the battery die and then recharge and hopefully the phone would automatically restart like normal, however the phone does not show sign of charging now.
So I tried to connect to the PC but it wasn't being recognized however when I press and hold the power button a sound of detecting a device sounds and then when I take my finger off the sound of detaching occurs. But I couldn't see anything happening, until I went into device manager, under "Other Devices" , "Exynos8890" appears which I know is the chipset.
This is as much as I know of the problem. How do I solve thins problem without trying to factory reset the phone and lose all my data?
PS: I didn't backup my photos (My baby children only copies) or Notes in NotePad, which has some very important info.

A-Media Auto (1024x600) 5.1.1

I just bought and installed this unit in my 2010 Prius from a seller on Ali Express
I want to install a custom ROM on it but first I want to make sure I can successfully boot into recovery in case something goes horribly wrong. The seller REALLY doesn't want to share that information with me, so I was wondering if someone here might know how this is done.
If you have a reset button...
Press it (with toothpick) and hold it pressed until you see blinking the lights of buttons...then release and press it again until you see the lollipop logo. Release it and you will be on recovery menu.
You can move on different options from recovery by pressing quickly the reset button and choose an option by holding pressed the reset
if I did help you, please hit "thanks" button

So I tried that, but on my unit when you press the reset button all the light go out and stay out until the button is released. The only time I can get the lights around the buttons to flash three times is when I release the reset button and hold down the power button. But when I release the power button and hold it down again after the flashes it just repeats the three flashes again like the first time. If I release the power button at any time it just loads up like normal. If I hold it down again when the lollipop logo comes on it just goes blank and repeats the three flashes again. If I press the reset button it just resets the unit again, if I hold it down it does nothing until I let go, then it resets the unit again like normal.
The three flashes seem like they mean something but I can't figure out how to get to the next step of actually starting the recovery. I want to flash a custom rom but I am afraid to do it without the safety net of being able to get into recovery if I need to, you know?
any update
I also want to buy this unit, but I'm just not sure:
Does it connect to all the functions of the Prius 3? Camera? Microphone? Steeringwheel buttons? Other?
Or do you need extra modules? Which?
Are you enabled to edit the basic car functions from it at least?
Found the thread on google, waiting for someone custom rom it, its good, everything works excepts its buggy, sometimes camera dont work etc that is why i also want a simlle custom rom on it
Edit: solved here : https://forum.xda-developers.com/an...pment/mtcd-intel-sofia-units-wifi-3g-t3533154
Could you explain me how? I have same screen but I don't even get those 3 lights pushing both reset + power at same time. Thanks
Hey guys, so I have this media and my camera doesnt work, I just bought this car and when i put to reverse just yellow triangle appears, i found on google that they might be a solution in my factory settings, but I dont know the password, so do any of you know it, i would apreciate any kind of help, thanks.
