Hello fellow XDA-forum members.
To start with , I've bought an LG E900 from Germany via Ebay about a week ago.
It is brand new (Updated to the latest available update on Zune) , even some stickers are still on it. The First four days of usage were normal ( all things worked as they should ). Then suddenly , two days ago I've experienced some issues while browsing the web. I've got several restarts and "no sound" issues.
After that ,I started googling and found that a lot of people have problems with LG optimus 7. I found that a lot of people have the same problem when they play games , well i still haven't occured any problems while gaming, only when browsing web. I did send a letter to LG to get more information about this issue(specificly).
My question is , whether this problem is related to hardware or software? If it's a hardware problem , then which chip is affected. I am willing to repair it on my own, if a chip is badly soldered (I do have some experience).

Hello dear members , today I tried to reflow my phone's motherboard components. I reflowed an Audio IC chip first , still same , restarted and loss of sound. Then I reflowed the RF Chips , still same. Furthermore I tried to reflow the Snapdragon CPU , but LG DECIDED to put SOO Much epoxy under it , that the chip couldn't get enough air during the reflow process. The result was obviously bad , some of the solder balls exploded under the chip and short-circuited it(at that moment , I realized that my phone is dead). Only reball + new CPU chip would fix my phone (or a new mobo ofc).
Best regards , Kiura.
Ok , today I got an answer from LG Electronics. They claim that It's not a hardware problem, this problem is related to software. They gave me instructions to factory reset my phone, which I've obviusly done before. They gave me 2. options :
1) Resetting the phone under phone settings - about (Which I've tried before without any successful results)
2) Dialing ##634# with password ********* - then a menu pop's up where you can test phone components and do other stuff , like resetting factory settings etc.
Today morning , I tried the second option. I'm gonna test the phone for the whole day surfing web and playing games , then I'll let you guys know about the results.
2) Dialing ##634# with password ********* This will install MFG application- see here for more http://forum.xda-developers.com/showthread.php?t=841892 or make a search for mfg app
Bah , after i plugged my charger in ,the phone lost it's sound again. Had one restart too. I think Factory Reset would not help , because it won't downgrade your OS.
LG insisted that the problem is in software.
Is there any possibility to downgrade the software on the phone or flash it ?
You may use zone to roll back your phone
(zone backup the phone before update )
I flashed my phone today , by installing EU OPEN rom on my Phone. Eventually without a success. Phone still has sound issues...
I think the problem is in Hardware.
If anyone may know something more specific about this problem , please let me know. I can't just dump the phone... Maybe a cpu or some chip is badly soldered on the mainboard(well that doesn't make sense , because games run just fine)? I just need specific information about this issue.

Best regards,Kiura.

So yes , when the battery is like 50 or something similar (or 44) some times (some times !) when i get a call (and i use my phone for bussines so this is kind of disturbing...) when call is recived phone reboots , or stays in a state in which the screen goes dark , vibrate is on (its enabled for call along with ringtone) and nothing only reset helps (using stylus)
I had official rom 6.0 (sucks but im sure everyone knows that fact) Yevg001 WM6.1 same crap , i really dont know whats wrong , but its like that since i bought it i suppose i just charge to full when i leave home and not worry, but there are days when i need to make and recive lots of calls from customers etc , and as the phone reboots there isnt any record what was the last call
Any one had this ? any suggestions , hell i'll even change rom if some one solved it that way , but i did that from 6.0 > 6.1 same
All help appreciated
i heard it is a defective battery circuit issue, i suggest you contact hp for exchange
Okay , but i've bought it in poland (well online) but i've got the recit, so this must be sent to HP,how much time can it take (i know they will give me some Toshiba G910 as replace for few days but...i would like to know some estimate from experience of any one who returned it to RMA
Thanks for the info i was wondering what is going on with my phone
My experience with hp guarantee service is excellent, they replaced my 614c bricked unit in only one week, with their pick and return service. they work with UPS saver service.
They ask me to send just the device (without battery, sd card, stylus and battery cover). Then all was as they told me it shoud be. In your case i dont know how it will be, as it is a battery issue the warranty procedures could be different.
Hi, this is my first post here I didn't have time (and will) to read the rules and everything, so I just hope that this is the right forum for this kind of request.
Since you guys have showed up to be people with nice expertises, I request your help to avoid going to any support center and spend money for something that by lucky means, may be fixed at home
The problem is that when doing some operations, the device freezes and no action can be done, whatever button I press or wherever I click with the stylo.
The only thing that can be done to restore for a while the correct functionality of the device is to remove and reinsert the battery.
I don't know exactly when this problem started to show up, because the device isn't mine, so I don't even know what can be the possible causes.
I have also to say that this problem occurred few times at the beginning, but now it happens more and more often making it impossible the use of the phone. Sometimes I even can't turn it on.
I've tried to substitute the battery, but with all of them, the problem remains.
After that I've tried the software reset, didn't solve anything.
The hardware reset didn't solve anything either.
I thought then that maybe the operating system was going nuts, so I tried to flash the device putting WM6.1 Stratos FE+ on it (of course, following the guide and without doing anything wrong), but nothing changed.
I don't know what else it could be, so before throwing this piece of garbage in the bin I ask here for the last sentence, if you can help me.
I have some pictures attached of the phone freezing and the screen tearing up (looks almost like The Matrix movie).
Thanks in advance.
Hello,
From my experience, i think your problem is due to CPU overheating.
There are similar threads on this forum, regarding your problem.
I advice you to check those threads.
have anyone fix that problem? i have the same problem, but 3months before i put a rubber between the cpu and the metal cover and it worked, but now again and the rubber dont help anymore
I didn't do anything still on my phone, I am waiting that somebody gives us an answer
The only thing I did was to reduce the backlight brightness, according to the problem this guy has on this other thread -> hxxp://forum.xda-developers.com/showthread.php?t=596927
But the only thing I've got after this is that the phone lasts a bit longer before crashing
trinity
also here.
somethimes I must leave it without battery an hour or so to power up again.
nothing help. reinstal everything twice. even in stand by it freeze...
it's a wtf problem .....
also I'm very curios for some remedy. I incline to believe it's a hardware problem .....
please if anyone know how to fix that problem then say it here please
I have same model and same problem, When i press and hold central navigation key and power key it power on,and it work,few minutes....
On Monday I will overheat cpu and you hear the results ... hopefully positive
yes, please let us know. And what you mean overheat the cpu? How?
I want to fix mine too...
Thanks !!
Dear friends, problem solved ... overheating of components on PCB...

THANK YOU!!!
I have exactly the same problem with my htc can any buddy help or any sujjestion in this regard.
I have the same problem however
First, I flash back to ship ROM WM5
Second, I try to increase CPU speed up to 420 Mhz by using Pocket Hack Master
http://www.wizcode.com/articles/comments/pocket-hack-master-speed-configuration-guide/
Everything is testing, if you have your experience pls share
File as attached:
1. Install *.CAB
2. Copy patch file into folder
I join with the same problem.
Nobody has an idea how to fix that error?
@ivanish: can u please share your solution!!
how u solved that freezing problem ? plz can u share ?
thinh30 its overheating problem of cpu as i experiance this freezing problem when media player is in use for long time or during usb connection with pc
i think cpu speed should be lowered to avoid overheating and not increased
it's not that , the screen connector is destroyed , i have the same problem , it's not CPU , use search , there were solved this problem few years ago
Hello all !!
I have a problem with my Leo, seen several times on the forum, but with a little thing more.
so,
_it freeze up often (with battery drainage, full when i go to sleep and shut off when wake up)
_soft reset alone
_i must do many (and many) soft reset when it freeze up, because it freeze on start up.
_and when it's happened, the part below the battery is hot!!
i've test many rom, with task29 whenever and hard reset after flash, and on every 1st start up, freeze...
Do you know this problem?
thank you.
"edit"I also tried to remove the micro sd is the same thing.
nobody has the part below the battery hot?
is it the ram or processor? (or both lol)
if possible at all, just get a replacement while you still can.
I have the same problems more or less. More specifically it freezes randomly ONLY when using the internet (on GPRS, 3G, I havent tried it in wifi), and when it does it gets hot on the part under the battery (really, what part is there?).
Anyway, I send it to the service (couldn't get a replacement), and they checked it but they found no problems
Oh, and i have tried e v e r y t h i n g I could in order to find out why that happens. With SD, whithout SD, Stock Rom, Custom Rom, ,Different Radios, Nothing Installed, you name it, but the problem is there. I am not sure though if I can connect the problem to my SIM card, or the gsm network in my area (doubt it though since I was using my old TP2 flawlessly), but I do not have the knowledge to even guess if that could be the possible reason of the problem.
HTC will ask you to use the stock rom and try if you still get the problem , if so, then your phone might be a defective one. go to HTC and ask for a replacement.
flash stock spl and rom and go for htc ,if hard reset didnot solve these issues then it is a defective device
thank you,
my leo is SFR branded, so I must go through them and with SFR rom.
to get a replacement, it will be hardly.
i'll try on thursday, when i come back home.
thank you very much.
If you've had it more than 7 days (including the time it took to get to you if you ordered it from the SFR website) they won't give you a new one... They'll send it off to be repaired which can take up to 14 days. I know... I had to do it twice in the first month until they finally fixed my microphone problem...
to see after the repair.
thanks at all!
HI, after 2 repairs,i finally have my hd2 !!
1st time, software uptdate...so nothing
2nd time they changed the motherboard.
Test for 2 days before change the rom lol
Hello guys,
I have a very strange but really bad problem: my omnia7 can't stay in standby.
When I press the power button, to turn off the screen and go in standby (so not the full turn off), my Omni7 wakes up alone, going on the unlock screen. In the same time, the phone rings with the ring that is played when you connect the phone for charging.
I've tried reboot, reset, hardreset, removing the sim-card, turning on/off "battery saver options" ... still that issue :crying:
Anyone has an idea?
I've flashed with a cooked rom (xda-devs Omnia7 Tango V4.0)
my current config :
OS version : 7.10.8779.8
hard version : 3.1.0.4
soft radio version : 2424.11.7.2
hard radio version : 0.0.0.800
loader version : 4.10.1.9
SOC version : 0.36.2.0
Thanks to any ideas, because that problem is killing me
my phone started doing this late last night too! i thorght it was because rain had gone into the power socket but if others are having same problem at the same time maybe not?
has your phone been exposed to water at all recently? is your phone jailbroken? cant realy think of other reasons
the problem stops when the phone is plugged in. is there anything that can trick the phone to thinking it is on charge? I have wphtweaks installed but the options there are not able to stop it
Hi,
I can't remember if my phone has been wet :/ I take care, so my phone never received water. But when I'm outside, under the rain, it's possible.
Today it was better, just a few times my phone wakes up alone.
I'll give you feedback in the next days. Let me know about yours
I managed to trick my phone into silence a few times earlier but it was difficult and then only lasted 5-10 minutes.
if yours didnt get wet it seems unlikely to do with water but I left mine ontop of the aga after removing the battery and over a relativly cool part. A few hours later and it seems to be working fine now.
I will report back if the issue arises again.
EDIT: Ahhhh!! STOP THE RINGING!!! started again this morning
Mine too !
This morning ... the ringing awakening problem !!!!!
But it was better this afternoon.
Really I don't know what happens.
Are we only two persons in the xda world with this problem????
this is realy weird now! mine was doing it in the morning but since about 12pm - 1pm it has been fine! I feel like its something to do with an installed homebrew app maybe.
I also have a custom rom but mine was flashed a long time ago and much older than yours. not sure which version
EDIT (1:10pm GMT): no problems since yesterday
EDIT2 (1:30pm GMT): again i spoke too soon!
Did you guys get this problem sorted out? Had the same problem recently and tried all the suggestions in other threads (bend USB pin, Reset/Restore Device etc) but nothing fixed it, so after being woken at 3am by constant charging tone, took to T-Mobile shop. They said it was a software problem. I said I'd tried all that and the most likely cause I'd seen on the internet was a duff USB port.
Anyway, T-Mobile sent it off for repair and 7 days later - returned and fixed. The repair sheet said software upgrade, but the phone had been reset to bog standard Phone 7, so unlikely. The T-Mobile repair tracking site (excellent) which shows blow-by-blow trace of what and where, showed initial software upgrade/no fix but I used their "contact us" facility to suggest a USB problem and by magic the repair tracking log showed a replacement USB port.
BTW - had to resort to an iphone and HTC android while Omnia was off for repair. Now I know why I like Phone 7 and can't wait for 8. The iphone GUI is so last decade and Android GUI is really just a copy of Windows 6.5 with XDA developers' tweaks isn't it.
Hi Wuzzok,
what do you mean by "bend USB pin" ?
Anyway, it seems like it's finished for me. I didn't get tht strange bug (soft/hard bug???) for a very long time. I just hope it's really over !
Same problem
Hi Folks,
I have the same problem, too. Yesterday afternoon on my way home the phone started ringing with the USB plug sound and always started up itself from standby mode.
As I have a custom ROM (mi7ROM) I first thought it could be a problem with the ROM - although I could not really believe it since it was running stable for months now. I flashed it again and nothing changed - still ringing and starting up itself
I managed to get rid of the sound by deleting the entry in the registry key "Local Machine\Current User\ControlPanel\Sounds\BatteryCharging\Sound" but that does not solve the real problem.
After reading here and in some other WP7 blogs I am sure that this is a hardware problem with the USB plug unit. As my phone is just 11 months old I opened an online ticket at "SAMSUNG online repair service" who promise to answer in the next 24 hours. So I just have to wait and see...
actual state

Samsung sent me an offer to send the phone in for repair - but what should I say, the problem solved itself. For two days now the phone works normal again. So I had to cancel the service call .
mine hasnt done it in a long time either. looks like its just a temporary thing. I wonder what caused it! For me it started after I was using my phone in the rain and the usb slide was open so thats my suspect.
You may be right. Mine is "quiet" now, since a long time. Water may be the cause.
Update
Hi folks,
mine is mostly quiet again, too. Only few incidents "happen" but they do not last very long - only a few minutes. It's somehow spooky but I do not want to send it in to Samsung now when the error it not constantly reproducible.
I agree with you that there might be a correlation with humidity although I am sure that it did never get wet and I almost always keep the USB-shutter closed. Who knows ...
Sent it in
Finally I sent it in for repair today. It started ringing permananently two days ago...
Now I have to wait and see.
Final state
Okay, I received it back... and it works.
First they did nod find and could not reproduce the failure and wanted to send it back - only with a new flashed image - but fortunately the technician called me and I could describe the problem again. After waiting a few hours, the fault appeared again and they decided to change the mainboard.
I hope, that's all :laugh:
Hello,
Me too it makes me after my omnia 7 is dropped in water, but problem solved.
Me too

Are you really sure that the problem is USB port.. Mine too behave like this. I've tried to remove battery, factory reseting, reflashing ROM. But nothing works. Mine is Samsung focus
post to remove
hi there
i want to be sure that my mobo is dead, so i'll describe my situation and hope that someone in here will help me to revive my precious note4.
my phone worked just fine until 2 weeks ago, then it started to bootloop whenever it got too hot and got back to normal state after being shut down for a few minutes.
i never got any emmc errors, so i figured out that maybe a fresh start would help. it had MM already, so i flashed it with the latest firmware i could find (N910FXXU1DRF1) and wiped it... the phone worked after this, but the problem wasn't fixed, and unfortunately, it died the day after.
now (and for the last whole week) i cant turn it on no matter what, and even when pluging chargers to the phone it doesnt respond. i've tried using another battery, but it didnt help (also, the battery works fine with other phones).
i've tried to get into download mode/recovery, but... no respond to that either. pressing the power button for long periods with and without the battery also had no impact.
btw, the phone would usually got hot on the top-right area of the screen, where the sd-card should be placed. (and i dont use an sd-card)
any help, advice or diagnosis will be welcomed
It looks like eMMC problem - he ded - do some more reading just to make sure that this is the case.
If you want a new motherboard, here are the options:
a. 910F or any similar Snapdragon - u don't know how long it's gonna last + AOSP ROM's up to Android 8 (for now).
b. 910A - bootloader locked - afaik is not possible to get a custom recovery & custom ROM, but I might be wrong + plus above
c. 910C or any Exynos - forum still active with solid options for custom ROM's - even a 7.0 TouchWizz ROM - go check it.
If you have $$$ go for another more recent phone. If you don't have money for a more recent phone (new or second hand) then - if I'll be you - I would choose the Exynos (910C) motherboard.
The only problem is - good, reliable source for the motherboard.
I have a 910C - it's rock solid and very happy with it.
Any decision is totally yours, read and learn so that you can live with the consequences of your freedom to choose what's best for you. Please, don't blame me for it afterwards.
