[HELP] LG Optimus 7 E900 (WP7.5) stuck on boot logo

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.

Phone works only under pressure

Hello there,
I've a cellphone (non-smartphone) which is important to me, after a recharge it started to freeze and shut down then the screen turn on and shuts down again and stay like that.
It only work normally if I hard pressed on the board, I also tried to change battery but still the same.
Do you have any idea what could it be and how to fix it?
Thanks in advance.

let the battery drain all the way to the 0%. ive had same issue few times with my s7 edge it would not respond to any command no matter what i do, then all of the sudded after i didint touch the phone for abouth 6-7 hours i put it on charge again and 0% was shown and started charging.
most probably its a motherboard issue and should be replaced at least in my case

Thanks for your response, i've left it unplogged for more than a day and still nothing. Should i wait longer?
How expensive would replacing the motherboard be?

I'm only telling from my experience, untill your battery is 0 it will be like that presuming it has somewhat same issue as mine . Try pressing buttons from time to time it could help to drain battery faster . On second hand market it should not be more then 40-50 euro. Also AliExpress has motherboards but not new, used

R.I.P S7 edge 2016-2019 will be missed

Same thing ! Phone just totally dead.
The same thing just happened to my S7edge today... I think it's a conspiracy so that we are forced to change the phone.
Sad, I liked that phone.
Nothing would work, it started at first a rebooting loop, then suddenly stopped giving any sense of life.
Doesn't show any indication when plugging the charger. nor responsive to any of the rebooting button combinations...
I even had it on stock Rom and never flashed any customer ROM on it or anything.
I think leaving the phone battery to drain as a solution only works if your phone was already on and it just gave a black screen, but it's still on.
But in my case, it was already in a rebooting loop and I suspect it is not even ON anymore, it just went totally off somehow...
So there is no was to know if the battery is draining.

update:
So I left it overnight. In the morning, I connected the charger and indeed it drained to 0% and started being responsive to charging again.
As soon as it charged to 20% I powered it on. It loaded into recovery, giving the no command screen. Then I went on and selected system reboot.
Then it rebooted and Android started, as soon as I tried unlocking it, it froze and started again into an endless rebooting loop until it blacked out again. Now again not responsive.
I will leave it to drain again. Does anyone know what I shall do when it gets to that endless rebooting sequence. It is obvious that Android had a malfunction... not sure what as I didn't do anything new last week..
Is there a way to get it through without factory reset?
Thanks

S7Edge Dead?

HI Everyone,
My device is not turning on nor its charging. It was having appx near about 40% battery left. Suddenly it start getting laggy and freezes. Error system ui stop working came and I decided to reboot it by normal way. However the display goes off and now no LED, no charging and not even opening into download mode or recovery.
Is my phone dead?
PS. before all that happed I was just browsing internet and it wasn't over heated at all.
If I want to recover data out of it, is it possible to send it to manufacturer and recover it somehow? or alternate way?
Thank you

According to me your network ic or capacitor is shorted. you should go to samsung but they will ask you lot of money. so go to a nearby phone repair shop.

It would have been great if my phone gave me time until Note20 comes up, now I will stick with my old spare phone until then.
I was curious if it can revive, because my phone was getting 0 care from me, I had my screen wet and lost the display two time however it revive after drying it for few day. Now it had enough of me I think. RIP now.

Dead SGS7 EDGE, battery or mainboard issue?

Hi all,
What do you think, what could be dead in my phone?
Phone was working perfectly, when I was reading some stuff using Chrome it stopped working [freeze], I pressed power button for few seconds and phone rebooted properly, I could use it for another about 20 minutes and then I got another freeze, at that moment I was not even able to restart phone with power button, when battery level was 0% phone came off, I charged it again and was able to run it for another about 15 minutes, I even managed to go to TWRP and saved a backup,:good:
Finally in TWRP mode my phone got a freeze and after that I am not able to do anything (it was freezed for a few hours and was not responding for power button at all) , phone is completely dead since then, I can not charge it, any keys combination is not working at all,
I guess it will be battery or main board issue but what do you think? I opened a rear cover, disassembled battery but physically everything looks fine,
Thanks for any ideas,
Cheers

its nearly impossible to tell, the two things you have mentioned (Mainboard & battery) are the two most likely to have broken....
Sounds like your phone is bricked unfortunately - you could try taking it to a repair shop for a 2nd opinion
