Hi good day, im a newbie here. I have problem with my LG Optimus 7 E900 Windows Phone 7.5, its just stuck on boot logo. The problem started last week, i was sleeping and i woke up because my pillow is kinda hot and then i found out it was my phone. It was hotter than the usual and it was not even plugged in to a charger, it was also stuck to the LG boot logo screen. I tried to unlugged the battery since i cant turn it off, waited for 3 -5 minutes and plugged it back in - still the same. I tried to do the Cold Boot, by holding the Volume - and Camera and tapping the Power button but nothing is happening, it just says Cold Boot and wont do anything. I tried to do the Restore, by holding the Camera button and tapping the Power and i got the screen that shows it needs to be connected to the computer. I've connected it to the computer and Zune automatically detected it and says the phone needs to be restored. For few minutes the restoration was complete and the phone started to turn on again. I was very happy but then, the problem starts again, the phone just turn off and stuck on the boot logo. I've unplugged the battery, after half a day i plugged it back in and the phone turned on. I reset the phone because i thought that it could theres no memory left but after few minutes, it happened again. So my phone is now useless, it will turn on for 10 to 30 minutes if i unplugged the battery for 3 to 5 hours. Is this a software or hardware issue??? I am really wondering why and Im kinda frustrated about LG or WP7 already.
If anyone out there can help me i would really appreciate it. If you have the same problem, lets help each other so that we can have our phone working again. Thanks for reading! Have a great day!
please help
This is hardware problem. You have to buy this board:
You can buy New SIM Card Micro-HD Flex Cable for LG E900 Optimus 7 from ebay.com, sefelectronics.com or mobile-cherry.com.
I recommend to buy it from mobile-cherry.com. It 100% works!

Hi sir, thanks for your reply. after two weeks, my phone starts working again. its been two days now and still working fine. what happened is that i tried to charge it when it was off, after 30 mins or so i turned it on and it works. but i noticed and smelled burnt plastic. i stick my noise on the micro usb part and its really smells something is burning inside but the phone is still turned on. i took off the back cover and i felt that the upper is hot and the battery seems to be ok.
i guess my concern is, is it okey to use this still? im afraid that it might explode or something while on my pocket. what would you suggest?
thank you very much!, i really appreciate it.
I solved this problem by disabling the detection of the position in the menu settings. You should have a lot of patience in being able to restart it at least once to enter the menu, possibly leaving it off and without battery for a whole night.

I though my battery died so I bought new one, but it doesn`t respond also.
On friday there was problem with display and device automaticaly restarted
I opened it and something like this is not connected anywhere. I can`t see anything in service manual like that. Do you know what is it and where it suppose to be connected ?
That's a holder for the stylus.
There's a small screw that goes through it when it's in place and it holds the stylus from falling. It's very easy to place it back!

Ok, thanks, so it`s not for battery so my wizard is dead definitely
It may not be your battery!
I had my wizard die in much the same manner as your's. I thought it was a gonner until I ran across a site somewhere with a whole group of people with the same problem with their wizard. I'm only guessing, but I think you let your battery run very low and the device shut down, which is alright, until you consider that it cannot charge without the operating system (Windows)
up and running! I had to cut the mini end of a usb to mini usb cable, strip the black and red wires and hold the black to the negative pole of the battery and the red to the positive pole while it was plugged into the usb port on the desktop computer for about 20-30 seconds. Then replaced the battery in the phone, booted windows and recharged with the home charger. It worked great, but now I carry a fully charged battery with me, in case it happens again and I,m out somewhere where I can't jump start the battery with the cable trick. I think this method is also mentioned somwhere on this site. Good luck and let me know if it works.......
Oh. I also though it is the problem with charging, but the night before my battery was fully loaded and in the morning the phone died without possibility to boot up. two days later I`ve buy the new battery and put into the Wiz...nothing.
I asked salesmen if it`s possible that the new battery is charged under possibility of the phone, but he said it`s definitely not. So I suspect that something happened to the hardware.
I`ve tried connecting USB directly to the battery also, before I buing new one, but it also didn`t worked for me.
Before it completely died there was several hangups on today screen and once even on the booting splash screen, with the strange situation where the radio ROM was not displayed at all :/ ??
After this several reboot sesions it has not started again.
I didn't catch the whole story from the beginning, but did you drop the Wiz? I dropped mine, and I am going through the same exact thing with the Radio not showing up. Mine only gets to the first splash screen, and enters an endless reboot loop.
If we can find a solution to this problem, I'd DEFINITELY love it. Until then, I'll still be sad.

Hi there,
As you can see I'm very new to this forum but I too have just come across this problem this morning.
My battery was fully charged yesterday and I had my alarm set to wake me up this morning but it did not go off. I checked and it was all set ok so I did a soft reboot. It hasn't come on since. A took out the battery for a while and it managed to boot up to the WM6 screen but then switched off.
Now it seems the device doesnt even switch on
IPL/SPL 2.22.002 (I think from memory)
OS 6.0xxx
Running the TNT rom not sure what version (was ebayed)
Have you plugged it in through the wall, and not the PC? Somehow mine came back to life this morning, all I did was plug it into the wall AC power WITHOUT a SIM card, and it booted like normal first try.

Hello i have a htc elf0100, and suddenly he doesn't charge anymore nore start. It's completely dead, i already tried a new battery and i even charged the battery with a battery charger. I have measured the contacts of the phone when is connected to a charger and i have 4,7V wich may indicate that the power of the phone is ok. But in fact it doesn't power on. Does anybody know what might be the problem
Mainboard
Is it possible to buy a mainboard for the htc elf0100, and if so where can i buy it and how much will it cost?
Have you had any further luck with this problem?

I tried repairing mine but no luck. There doesn't seem to be anything wrong inside it. Actually I had just finished refurbishing mine and for 2 days I was admiring its brand new white covers... Then, all of a sudden, the mobile turned off and doesn't respond to on/off,resets,chargers ever since. I am also guessing that my CPU must have been destroyed... :-(
I solve this problem whit the rework station, you need to heat the board, like 2 minutes in 400 Celsius, tried to don`t burn the conectors and the stikers.
Yesterday, after 2 months, it accepted the chrarger (led on) for... 1 second and then it started booting (for 5 seconds) but died again...
Wow! It responded again! This time it turned on and stayed on in bootloader! So I flashed it, and it WORKS!
So my tip is: every time you try to turn it on, always try in bootloader mode. So if it turns on, at least you will be able to do something!
Hi papajohn
how did you get it to turn-on again?
mine's dead no power response at all, completely dead, no tricolor, no white screen, no response to hard reset, can't enter bootloader, no orange led indicator when plug into power supply.

same here..
Hello, a while back I posted a charging problem, which turned out to be the Mini-USB and Wall Charger was bent, and before that, the Mini USB outlet in the phone broke entirely. Well, another problem has arisen, as finally got a new charger yesterday, and worked perfectly. So, I shut it off, and left it to charge overnight. Now, the problem? All of a sudden, it refuses to boot. Held down the power button for 5 seconds, 20 seconds, and a full minute. Nothing. Any suggestions?
~Infinity
nothing AT ALL? or the screen turns on and gets stuck?
if nothing at all happens, try the battery jump start method
Well, after constant trying at starting the phone, I managed to have it boot after hours. What happened? During the boot,where it displays Windows Mobile 6, a line appeared, and the phone darkened, and then crashed.
What the hell.
I suggest a hard reset......

....................And how can I hard reset when it doesn't boot, and whenever it does, crashes during it?
Anyone that's here help?
I'm currently having the same problem with mine. Hard resetting didn't work for me but you may as well try it.
If you can get it to start booting for just a few seconds you can hard reset it without loading the operating system. As soon as you get it to turn on, hold down the Wifi and Voice command buttons (one's on the left, one on the right). After holding those down, press the soft reset button (the little button on the right that you can press with your stylus) very quickly and release it. If you hold the soft reset button too long, it will perform a regular soft reset and you'll have to start over, so do that quickly.
A black screen should come up and tell you to press your send button to hard reset your phone.
I have similar problem,It's turn on to the logo that's always shown when boot and then it show the logo till it discharged.I tried hard reset,but it's still the same,i post 2 topic's in this website and no one help me
i too am facing the same problem, i was able to start it a few times but it crashed after a few seconds each time. i m gonna charge it all night and see if it starts. right now all i m getting is the red led. i really hope someone finds a solution soon.
With me it was my battery that caused the problem. Try it with the battery of another wizard. Succes, Rietje
ok so i charged it for more than 12 hours and my wizadr still didnt start.
I then got a NEW BATTERY and my wizard turned on within the very moment i pressed the power button.
So any one who is facing a similar problem should try a new battery.
Yea,this is a second time when i have this problem.I both A new battery,BUT IT STILL THE SAME!!!
First time when i both a new battery it was working fine,but now the battery won't help

try a battery frm a friends phone. u ll be sure that the battery u r using works fine. if ur phone still doesnt work then u need to have it checked.
i have same problem,,and i use T-Mobile MDA Vario
is it just battery problem or not?and if the PDA inactive it can still charge or not?
and i usually use blackberry charger to charge my PDA,is it ok?and is there any possibility my PDA can't work again?i hope not
pls help me..
Well for starters, charging your phone overnight will probably damage the battery over time. It's only the newer phones and batteries that are able to withstand extended overcharging times without serious damage to the battery. With older phones including the K-JAM/MDA Vario, the battery is meant to be charged till its full, and no more. If you overcharge it, you run the risk of damaging your battery and possibly the phone too.
If a new battery hasn't fixed your problem, the problem lies in your phone's mainboard.
Try charging your phone from a USB port on a computer to see if anything happens.
I bought this phone new on December and today I noticed a few random reboots until now, when the phone turned down and didn't rebooted.
Now when I try to turn it on, the LG logo appears for 2 seconds and the phone turns off again. I've tried to do a Cold Start pressing Volume Up, Down, Power and Shutter, and the phone keeps turning off just after the "Cold Start" appears on the display.
I have no factory warranty as the phone was bought overseas, so anybody knows what is happening?
Thanks
Did you check out this thread on random restarted?
http://forum.xda-developers.com/showthread.php?t=1136610
Have you changed anything? Dropped it? Used it in a harsh environment (hot, humid)?
Did you flash it? I thought manufacturer warranty was valid even if the phone was bought overseas.

Thanks guys. I found the "problem" and it's the charger, actually the USB cable of the charger. It's probably stopped working in the middle of the night and as I needed only to use the E900 24h later, the battery was dead due to lack of recharge.
When I plugged my old Motorola Micro USB charger, the E900 simply turned on as usual and it's everything fine now.
The only strange thing is the original Micro USB cable is visually in perfect shape, but that's it, never trust in these bulk generic cables and sorry for the false alarm.
Hi everybody
I have a problem with my Galaxy S5 (no custom rom, official)
I normally used my phone, I locked it. But, after about 10 mins I tried to unlock my phone, but nothing happens
I tried to reboot, nothing happens. I tried take out and put the battery - nothing happens. So I searched on Google and tried some keys combinations, but nothing happens. My phone has about 80% battery. I tried to charge it in the charger, but nothing is happening (black screen, no notiffication light). Also I tried to put off my SIM and SD Card, but nothing happens
Do you have some skills in it? Can you help me?
Few days ago, I faced the same problem..
http://forum.xda-developers.com/showthread.php?t=2853472
Then I'd to take it to the Samsumg store.. And they return it back in 2 days and said me it was a software problem..
I wanted to do a recovery reset, but i can't boot my phone anymore, also the Kies doesn't see anything, so. Did you really think that is a software problem? Because my phone won't vibrate at boot. So maybe it can be a hardware prob :/
EDIT: Phone started blinking red light... (nottiffication), I tried to charge it, but nothing...
Mate as mentioned early, same problem I faced..
It'll be better, if you return it to Samsung customer care..
You seem to be saying that the problem occurred unexpectedly. So presumably this isn't subsequent to a flash error, newly installed app or a trauma (dropping the phone, etc).
First ensure that your battery is charged, plug in the phone to a charger as well and try turning it on. If at all possible, borrow a battery from a friend's S5 or go to a store and borrow a battery for 30 seconds to confirm that the battery isn't the issue.
If the problem persists, then remove the cable and battery. Then put the battery back into the phone and press and continue to hold in this order, the volume down key, then menu key, then power key. Hold all three until the screen powers up (about 5 seconds). If this doesn't work.. the most likely problem is a damaged power key - try pressing hard or "wiggling" it to see if that makes a difference.
If you still can't start the phone, then see if a local cellular repair shop has a "jtag jig" that you can borrow. Or you can buy one on Ebay for a few dollars. When this jig is plugged into the USB socket, the phone should automatically restart.
If all of the above fails (which is unlikely), you would seem to have a hardware problem or unknown origin. Which would be very unusual. If your phone is under warranty, make a claim. Otherwise get an estimate to repair it.

If I hold all 4 buttons at the same time and connect the phone to PC, PC recognises the phone for a few seconds. Well, maybe not recognises, I cant see it, but it plays the same sound as if connected flash drive to pc. However, everytime it disconnects within a few seconds...
I´m in the same case, but I was flashing the Galaxy S5 with the four files ROM and the pit file using Odin3.09. All the process ended well, but after rebooting there apeared one Screen sayin something like "Some files at this phone are encripted and there can´t be modified......." so I did a manual reboot and take off USB cable and from this moment the phone don´t do anything but giving a sound when I plug USB to computer cable and I can see new COM --> Qualcomm HS-USB QDLoader 9008, and there repeat a loop.
I´m still looking for a solution, but it gives me that there is time to change phone.
Possible Fix
This thread is old but idk if this was ever solved, so in case anyone else ever has an issue like this. My Gf is still rocking this phone so i've had a little experience with it. The phone wont turn on or charge. I got it to work by sticking a flat head screw driver and prying it fairly hard against the bottom of the battery (the side closest to the charge port) and forcing the battery harder against the metal contacts. While pushing the battery I turn on the phone and it starts right up and continues to run even after letting the pressure off. I've noticed this happens every few times i take the battery out, but this method has never failed for me turning the phone back on. Hope someone finds this helpful.

weird, youd think that bending the tabs out to force contact with the battery better would do the same trick fwif
