LG Optimus Titanium Urgent

This was a Customers phone that they brought in and said that the phone seems to be broken is there a reset button. So I turned it on and it booted up fine the all of a sudden it decided to stay on the LG logo and now its on a white fuzzy screen. I do not know if it has been tampered with a.k.a. rooted but wanted a general opinion on what a fix could be.
Thanks in advanced for any help

Check the water damage sticker.

Thats the first thing I did but they are both clean

I used to work at Sprint as a technician. If you have access to replacement parts, try replacing the screen if you can't get to the home screen. It's an easy phone to open up, I still remember.

the screen is working fine and it only bugs out to the white screen every now and again. The digitizer is in good shape and the LCD has a clean picture. The phone just stays looped on the LG Logo for now, and unfortunately we dont have parts for this phone since its not a newer phone so I cant throw anything at it

If the screen goes white randomly, then it's probably either a bad connection (check the LCD's ribbon cable to the main board), or liquid damage that didn't make the sticker go red (it happens). It sounds like physical damage. Hell, for all you know, the person could have fudged up the software, panicked, and tried to beat it to hell to make it seem physical, but I think that's going out on a limb.

true, i believe its more of an internal board issue than a bad connection. The phone does have a good bit of physical damage to it so it could be that. Thanks for your help

N5 repair in shop

I left my Nexus 5 in for repair a week ago to a local phone shop, it had the faulty power button problem which was causing a bootloop.
Fast forward, they tried replacing the button with another but said the new button did not work,
They now say that its likely the motherboard and have ordered one for the phone ?
Does this sound like a genuine explanation or have they possibly damaged the motherboard by a botched job at soldering ?
Cheers

I would suggest getting it back and doing a visual inspection because a new motherboard is expensive.

9 days later , I Phone the repair shop today and they said my phone cannot be fixed , worse still they don't have it but its "on the way" from a courier someplace.
Very poor service that they took it in the first place saying "no problem , we can fix that in a few hours"
The phone was still working when i left it in but now im afraid when it comes that it will be totally unusable , my suspicion is that they may have messed up the soldering.
The guy has apologized over the phone but said i need a new phone and offered me another phone (they dont carry nexus) at a discount. but I'm still fuming.
Not sure what to do.

Not sure if they did screw it up or whether there is a problem in addition to the power button.
You may as well wait until you get the phone back Definitely check the imei if possible to make sure the company returns the correct phone. Examine it closely for any other potential damage/changes from the original.

Thanks for that, any particular things i should look for ? Im thinking of taking it into another place for a second opinion, the phone was working intermittently before i left it in , meaning i was getting a few days of good use than maybe an hour or 2 of constant rebooting that was definitely the power button .
Also do you think i should ask for any compensation from the company ? its hard to know.

I would definitely look for stray solder, damaged ribbon cables, damaged motherboard connectors, and broken clips. If the repair shop did something to brick it, there may be no signs of physical damage.
Rather than send it out again, you could look for a used N5 with a smashed screen and working motherboard. This way, you could just swap out the motherboards and you'll have a few spare internal parts.

Thanks again, I had a look online at the teardown video and it seems fairly straightforward to swap out parts (i previously had changed the battery myself) .
I just don't understand why they could not fix it, especially when he said they will put a new motherboard in it. surely that would have sorted it . just dosent make sense, perhaps they just cant be bothered ordering a new part.

A new motherboard? That should completely solve any problems since nothing on the motherboard can be replaced by a cell shop, even lg, unless the shop damaged something on the lcd.

Yes he mentioned changing the motherboard for a new one, you dont think even the power button can be replaced on it ?

Sorry about my confusing post.
Yes, the button can be replaced, but that is about it. There are only three solder points for the power button I believe. The wifi chip, emmc, and sim reader cannot be replaced.
Hopefully, it will not cost too much for the replacement motherboard.

Display Screen is pixel or scrolls

Hi,
I have Nexus 5 and was running good with Marshmellow and suddenly one day the screen started scrolling up. Restart or factory reset did not help. While starting the boot logo was also corrupted and I use to get is display with random pixels lit with different colors, mostly white and red. So have tried different bootloaders and even downgrading to 4.4.4 but the issue is still there.
Called up Google and LG as well. Since device is not under warranty now, it is going to cost for repair. So would like to know if there is any solution to this problem before I try the repair or give on this device.
Appreciate any suggestions. Thank you,
Sandeep.

Was the phone ever dropped? It's possible that there is a loose connection inside the phone. I suggest removing the back and inspecting the phone's internal components and connections.
If everything appears fine, it could be A problem with the lcd of motherboard, neither of which is cheap to repair. I suggest trying to find a used nexus 5, either with a smashed screen and working internal components or one with a working screen and damaged internals to troubleshoot your own phone.

I do not recollect dropping it. I would wait to see if any better option comes up. And will keep an eye for an broken Nexus to see if I can get the motherboard swapped. Thanks for ideas though.

Phone COMPLETLY died while i was using it.

As you can see in thread, phone just dead. Dunno what happened. I bought it an year ago. I've tried to connect it to computer and it was visible as QHSUSB bulk but now i can't see it there. It doesn't react for turning on. I can't get into download mode, recovery mode. Very long time ago i flashed Android MM from xda and it was working good. It had ~50% of battery when died. I've tried to put off battery and then connect to pc but still nothing happen. It has broken screen (was working good) but i've done it in September 2016 so. I can connect it to Linux but i think it won't help too. Any fixes? I think they won't take It at warranty because of screen. Phone looks like dead for ages :<. @edit IT'S NOT DEAD! I've disconnected something from battery this longer one and when i click power i can hear "something" in the phone. And it gets heater so looks like processor is working. But it's still not visible in the device manager.
edit2
i know emmc pinouts.

While I was using the phone, with battery at 66%, the exact same thing happened to mine. I'm sick of it. Time for a new phone.
(Had the rooted V15c image on it, no broken screen, only the camera issue - should someone care)

Same problem here, what is happening . My phone was approximately 80-90% and it suddenly turned off and I can't turn it on ..

bump

Phone went black with warning
The same just happened to mine. It was fully charged and I was using it and then the screen went black. There are no lights when I plug it in, no vibration after pressing and holding the power button. Nothing
I've connected it to my pc and a driver installed, I think the same one as a post above (QHSUSB) but still the phone doesn't respond in any way.
It's the European H955 on official MM 6.0.1 no root or mods and is out of the one year warranty yet was in excellent condition. Does this mean the phone is for scrap and nothing can be done?

Hi, I found a solution to repair the phone in this state. I start by telling you a story, a long time ago I had an HP laptop. video card was detachment from motherboard, and to a stick again we used a method called reflowing. I thought that the phone has the same problem, however we have nothing to lose so I opened the phone I took out the motherboard and started to warm up each chip using a hot air blower. I mounted the phone back and now works like new. I apologize for my bad English I am from Romania.

Any one tried this method and succeeded may please inform on this forum

My phone crashed, would reload to lock screen then restart and finally would not start at all. Before this the rear camera stopped working.
I had reset, flashed a new Rom and replaced the Camera which didn't solve the issue.
After the phone died I tried reflowing though I had no heat gun so I just used the oven. 200c for 7 minutes after disassembly.
That was about 8 hours ago and I am typing on my phone.the Camera is also working.
I will post if it stops again. I did it as the phone was dead and I had nothing to lose.

I have the same problem, and I am interested in getting a heat gun for this purpose. What specific parts of the phone did you reflow/heat? (in terms of the chips, or the entire board.)
Thanks in advance.

I did not heat the whole motherboard, just the chips under the shields.

What part of the phone did you reheat exactly? The whole phone? or did you take all the plastic out?

Also be sure to take off the rubber part on the back. The purpose is to remelt the solder.l, so only board and nothing else.
To disassemble there are some videos on YouTube. Remove your sim card before taking off the backing
Remember this is a last resort, you could end up with a completely dead chip.

Thanks for the information. Is there a specific way you have to remove the shields, or do I use a soldering iron to get it off? (And if so, does it do any good to solder them back on?)

Did it 395 degrees Fahrenheit (201.66 Celsius) for 7 minutes, I preheated the oven. The camera and everything now works fine.

You shouldn't have to use a soldering iron to take anything off. At least not as far as I am aware of.
I should note that as of this morning my phone when blank and will no longer turn on. I will try reflowing at a higher temperature as some solder may need a higher heat but I am not optimistic that this is a permanent fix.

Hey everyone !
First try to connect it in emergency mode to the computer in order to flash with LG UP. If you cannot boot into emergency mode but the device appers on your computer ( and PC is unable to connext into GF2) maybe you could burn your motherboard.
I burn one 7 months ago with my device resting on my pocket so its a common problem for this device (as official support told me so its full covered by guarantee )
Hope you can solve soon !!!

Question Screen Replacement Not Working?!

So the sad sad day came when my niece dropped by my house, jumped on the couch, and broke my phone. No physical damage was down upon first glance, but as soon as I assessed I realized the LCD won't respond.
Phone was still on, and even functioned like normal, touch screen even worked. I could blindly answer calls. However, no display.
Took it to one of my tech savvy phone repair guys. Said it requires a new LCD. Cost me $400 bucks, and a month and a half of waiting for the part to arrive in Canada.
Arrived today, and my tech calls to say, with the replaced screen still no screen.
He reinstalled twice and checked all connections.
Any ideas or am I simply put SOL?

For this price, there is the frame too?
Is it exactly like before?

Yes, it is an original part, and includes the frame.
Both parts don't show a screen but turn on and function perfectly.

Several hypotheses:
The new part is defective (rare, but it happens).
Damage to a component during disassembly/assembly.
Other faulty components.
In this video, replacing the screen requires time and material.

Thanks for the suggestions. Yes I also figured there is some damage to other components, not due to installation because the symptoms are the same. Maybe due to it bending when she stepped on the phone. Oddly enough there's no physical damage.
The YouTube video there uses the same frame. That's a very tough fix. This came with screen and assembly. None of that work was necessary.

Of course, but personally given the price of the parts on this phone, I would have had an estimate made beforehand in an approved Xiaomi center.
I had the same case with an Honor, I replaced the screen for nothing, but given the price of the phone, direct trash.

Annoying indeed, the guy who changed the screen can't diagnose the problem?
Suppose the motherboard is the failure, screen + motherboard = not far from the price of the phone + labor?

I think it's a hardware issue or thermal issue idk, but mine has been blacking out lately and if I reboot to fastboot sometimes it starts working again, I tried the heating the battery up to no avail. I am also getting glitches on the screen like when you overclock the gpu too much so I think it's the gpu drivers/chipset and something with the power/transmission

Exactly. Too much cost. Also it's not exactly the whole motherboard as the phone is fully functional outside of the one issue that the screen is black. It's got to be a chipset defect.

Can't be thanks for mine as it's stable, and stays on. Thermally it would shut off the phone when overheating. Drivers/chipset is what I'm guessing also.
