Thanks for posting the youtube link. I can't even quote the post because it involves an external link. The video was vague on details and the quality is crap but it did the trick.
[Atrix 4G Q&A, Help & Troubleshooting] Metacat:
My Arix got under the tires of a car (please dont ask how :P) and only the digitizer broke, then i replace it with an OEM digitizer from amazon and now the proximity sensor is malfunctioning (Turns off the screen when im not near it or doesnt turns off when im near it), and there is a line of the screen that doesn't respond to tact. could it be the digitizer that came defective, or maybe it was the installation? oh, the other digitizer was broken and all but the light sensor was working fine and also the other thing. Sorry for my bad grammar.
[Atrix 4G Q&A, Help & Troubleshooting] keithgrobertson:
I replaced my digitizer, and had the EXACT same thing happen (not the light sensor but the line in the screen that doesnt respond to touch).

Get a new digitizer, but get it from someone else.
[Atrix 4G Q&A, Help & Troubleshooting] Metacat:
That's what i feared, did you changed it back again afther that, and did it worked? and thanks.
[Atrix 4G Q&A, Help & Troubleshooting] keithgrobertson:
No. I sold it and let someone else deal with it. Didn't have the time to replace the digitizer again. Too much of a hassle.
[Atrix 4G Q&A, Help & Troubleshooting] Jorzebradan:
I just replaced a digitizer on an atrix... i didnt put any adhesive on it because there was what i thought was adhesive strips on the digitizer... but there's strips on the screen that doesnt respond, i heated it n tried reattaching the digitizer a few times n sometimes the home and back button will work, sometimes they wont... any suggestions? could the lack of adhesive cause this?

Go the ifixit route!

Just went through 3 digitizers in my repair, and wanted to share my experience/caveats

I bought one digitizer from All4Cellular for $25, and the others with a 20% discount a few days later, for $20.

I installed

the first using the RepairUniverse Youtube 'how-to' method, and had a heck of a time threading the flex cables through the slot. Bent/twisted it too much, and nothing responded on the touchscreen, so I read some forum posts on how fragile they were, and regarded that as user error.

Got the idea to move the LCD screen from another RepairUniverse YouTube video and a previous post here, and tried installing the digitizer from the front face of the phone. It was still a delicate matter to bend the flex cable so that it fit through the slot, and then re-position the LCD and align the sticky strips of the digitizer on the LCD and casing. Part of the digitizer worked this time - a 1cm vertical strip on the left fowled any attempt to touch icons or use a keyboard, so I thought I had damaged things again (doh!).

Hoping third time was the charm, I completely disassembled the phone using the guide in the 'ifixit' link, since a digitizer/case assembly was suggested in another thread. The rear camera just needs to be raised above the casing so the thin plate can move upward, and the LCD pops out easily if the sides of the casing are delicately pulled. The digitizer can be positioned easily and with minimal bending/twisting of the flex cables.

When reconnecting everything the third time, I noticed that pressing down on the front camera / digitizer connection *with the rubber boot in place* didn't pass when pulling the connected assembly upward. So I pulled the rubber boot out of the way and snapped the camera / digitizer connection firmly, then re-inserted the boot. A loose connection might have been the culprit for the nonfunctioning part of the digitizer in the second test.

@MrSaba - I had the same issue with capacitive buttons - perhaps because the screen senses touch and disables those buttons. Replacing the digitizer solved the issue

trouble

Hello friends,

Here's my story - broke a screen, as usual slipped from my pocket. though broken, digitizer worked fine. after replacement with new one (digitizer only) - no luck it didn't work. bought a new one, this time with a plastic part around it to avoid damage to it's cable. after careful repair no luck once again - does not work at all. downloaded a testing app (i was able to remote control the phone with a piece of soft called androidscreencast), everything is ok, except digitizer. checked and rechecked all ribbons and connectors 10 times, nothing seems to be broken or twisted.

what's your opinion, is it worth buying third one ? what part of my repair went wrong ?

thanks
[Atrix 4G Q&A, Help & Troubleshooting] jjwatmyself:
Not all digitizers are created equal. The ones that ship with the red stripe on the backing are junk. Spend more money and yes buying with a frame is key. Did you try reinstalling the original screen or did that ship sail already?
[Atrix 4G Q&A, Help & Troubleshooting] drZeT:
The first one was with the red stripe indeed, from china. The one with a frame came from UK, "used but tested OK". original screen is gone - tore off flex cable while removing.
[Atrix 4G Q&A, Help & Troubleshooting] drZeT:
Well, update...

2 screens bought on eBay were BAD. Had to wait full month for authorised motorola service to change the digitizer. Must say though that both merchants on ebay refunded, no questions asked. Lessons learned - pay more, wait longer, never give up :)
[Atrix 4G Q&A, Help & Troubleshooting] D!T:
What I noticed on their video was that their folded digitizer connector magically unseats itself during the disassembly transition. I had to pry mine off based purely on guesswork and think I might have broken the flip-chip that is stuck onto the frame with double-sided tape. Like yours, my touchscreen doesn't respond at all, despite there being no cable tears. I'm going to try and re-heat that flip chip and maybe get the connections to work again (doubtful).

To anyone else out there attempting this... when you go to remove the touchscreen, HEAT THE CONNECTOR so that you can gently pry it out!
[Atrix 4G Q&A, Help & Troubleshooting] markwoo:
Bad screen I got 3 before it worked its fine now if old one partially works new one doesn't screen is junk took mine apart several times to figure out screens were junk...guess they felt sorry for me give me my money back plus free working screen.from amazon

Also that lock clamp u mentioned first video I watched didn't show unlocking that I just pulled it out and pushed back in it was the 2 screen that I figured out it needed to be pryed loose by the white clamp but guess I didn't damage it..
[Atrix 4G Q&A, Help & Troubleshooting] Jonnym:
I have just put in my second digitiser. The first was one had a red stripe, which was junk, the second on I bought had the plastic round the edge and the digitiser.

I put it in and it worked fine no dead spots at all. Then 12 hours in it started to stop working intermittently. Then 24 hours after that while on charge its dead again. I reflashed notattrix and still nothing. I've confirmed all the ribbon connectors are firmly in place and everything looks right.

Any ideas whats wrong?

thanks

Hi,

Since applying the "non-official" NoDo update the phone works fine with Copy and Paste etc. but I can no longer access the boot loader screen. I press all the correct buttons at power up and the Samusung Omnia screen appears at boot but it hangs there and does not allow the Microsoft support tool to connect.

Any ideas how to revert or sort the boot loader issue? (it's a locked UK T-Mobile phone)

Thanks

Why my LG Optimus 2X freezes and/or reboot?

Most of us have the same problem, we are trying to find a solution. In the meanwhile we can solve only removing battery.

Is it related to baseband version?

It does not seem related to baseband version. The problem is present in last baseband versione too:

1035.21_210110405

FRG83G

V10b

Is it related to ROM Version?

Apparently it happens on both stock and custom ROMS

I read that it is due to wall charger problem

Some of us have the same problem recharging both from USB PC and Wall Charger

I read this is due to overheat problem

Some of us still have the problem in standby mode with battery under 25° C.

LG told me to ask for a replacement

Some of us did it and had the same issue on the replaced phone.

I read it is due to hidden menu/car navigation/ecc. ecc.

There are no prooves about it.

Could it be a ROOT problem?

No. Same thing happens on both rooted and original phones.

I got it. It's a SD problem

Some of us has this problem both with or without SD card

So it's a HW problem

We are not sure about it. Most of us (me too) think this is a SW related issue. Some other thinks about a HW one.

Anyway it looks like a Nvidia/Tegra related problem.

It happens on Motorola Atrix too:

http://xdaforums.com/showthread.php?t=969974

http://xdaforums.com/showthread.php?t=1009510

So: what can I do?

Follow this thread and partecipate :)

Try to install latest version v10b and do a full reset.

Try to uninstall the "Any cut" application.

Try removing your SD.

NOTE: These are temporary solutions while we wait to understand something more.

Nothing else?

Sure, you can add informations here to keep updated the FAQs.

What about contacting LG?

It looks like something is moving and a new update will be released soon:

Hey, new V10C is available. Does this solve?

Not sure yet. Some of us still have problems, but some others solved with this upgrade.

How can I help?

Mine has now shut down 3 times while i was in a call, battery pull on each occasion to rectify the problem :mad:
[LG Optimus 2x] lmerega:
Added in the first question that pulling off the battery temporary solves.
[LG Optimus 2x] naimmkassim:
1 week ago I do faced 2 time reboot each after receive sms during standby mood.

Dont know what happen.

Later I remember the reboot problem started after I had installed "Any cut" sw and started to activate the hidden menu.

Then I uninstall it and now haven facing any reboot no more.

Already 1 week pass and no reboot at all. I also never restart my O2X yet and seem everything is OK, no lag or etc on the system.

Hope this help.
[LG Optimus 2x] marco_ch:
Was using the original lg rom only for a good day and had one shutdown. Switched to custom rom and didnt have a reboot or shutdown yet in over a week. Appears to be software related.
[LG Optimus 2x] follo:
Useful topic, thanks!

My experience in 15 days of use.

with stock rom V10a and external sd:

- 1 time screen locked black in a warm day during standby

with stock rom V10a without external sd:

- many times screen locked black just after a notification (almost always after sms incoming notification)

with official rom V10b without hard reset and without external sd:

- 1 time reboot after pressing power button to exit from standby

- 2 times screen locked black the day after I've changed the useragent setting from the hiddenmenu and installed "AutomateIt" app

with official rom V10b after a hard reset 2 days ago and without external sd:

- no problem till now (2 days of use)

All the time I used both original charger (at home) and a generic usb adapter with an output current of 1mA (at office).
[LG Optimus 2x] choccy31:
This is the sort of stuff that should be sent to LG to deal with. Not the idiots at call centres but the people who made the phone and get them to work on it.

Problem with these phone guys, they make a phone and then just stick out to the salesman and then when things like this happen to everyone we get no support or real contact.

It's always send it for repair. The phones are like a month old and that is really a valid response?

Time LG were held accountable (as well as other company's)
[LG Optimus 2x] lmerega:
Ok, added some "Possible solutions" :)
[LG Optimus 2x] withoutwings:
Good thread, will hopefully cut down on some of the idle speculation that has been going on!

I believe that it is a software bug, namely in Nvidia's cpufreq-dvfsd driver. I saw this process misbehaving when doing a 'top' command via an ADB shell after it froze, and I'm not the only person to have witnessed that. I've posted that info over at MoDaCo.

As kholk is the only person other than Paul I know around here who might be familiar with a Linux kernel, I've asked him to take a look. Not sure what will come of that, if anything.
[LG Optimus 2x] withoutwings:

Read from the postings that, for charger-specific reboot/lockup problem, it might be better charging from a computer USB port or a charger with lower current output (I think someone is using as low as 350mA).
[LG Optimus 2x] mikeyd85:
Fyi, I've never had AnyCut installed and I've had these problems.
[LG Optimus 2x] lmerega:
Yup, we do not have still found THE cause, but some events.

We are trying to understand if they are related to the issue.

I am reporting infos from the other thread and from this one to help people ti find a partial solution.
[LG Optimus 2x] follo:
Very interesting withoutwings

A problem related to tegra system could explain why LG can't solve anything?

Checking all of the messages I can see that the problem is one ( phone locking/restart) but the symptoms are very different and almost always unrepeatable.

Is also strange that many people have a lot of apparently casual restart/lock and many other people have no problems. If a part of source code is corrupted I think the problem should occurs for all the phone.
[LG Optimus 2x] withoutwings:
Not necessarily. In embedded/real-time systems, timing is crucial and in some components varies according to manufacture tolerances, heat, etc. Also everybody's phone has different apps and they do things at different times so you can't say that everybody's phone is just "the same" as everyone else's.

And this bug could well be one that only happens for some very specific condition that the original developer didn't forsee when he wrote that code or tested it. But the law of chance means that so many of us are seeing it - some more than others, and some days worse than other days.

So this would explain why people think that doing something like switching launcher or taking out an SD card might be solving or making the problem worse, because every action can and does change the likelihood of this specific condition occurring by changing how the phone behaves overall, workload, sleep time, etc etc. And why all these "solutions" that people are posting are so random and unrelated but each person is convinced that theirs is the one that works!

Basically, we need more evidence from logs to see what is

really

going on...

Are you guys still having issues with this?

I got my O2X just 3 days ago. I've had random reboots, and a few BSOD.

BSOD:

- plugged into USB (PC)

- after it went into stand-by

- plugged into factory charger

I also had 2 instances where it turned it self off completely, while it was charging with factory charger. When I go to take it out of stand-by, I see the LG logo and it turns it self on.

Phone dead???

Ok, so I seem to have had this problem, but mine won't turn back on!!

I was running CWM 7 Nighties, on #112

My phone was charging, and when I picked it up to use, it was off!!

I have tried NVFlash but it sticks on "waiting for bootloader initilization"

I have tried this several times,in several USB ports, and several PCs, including different OSs (both 32 & 64 windows)

Although it gets to the aforementioned "waiting for boot...." message, no other signs of life are present, the screen is completely black, no LED (was there ever one? :S)

Nothing I have tried seems to work, and I don't know enough about NVFlash to go playing around with flags

Basically I'm worries my phone is entirely frigged!!

I have tried contacting the store I bought it from 3 months ago, however, they haven't replied yet! and it looks like the don't sell the phone anymore, which is worrying!!

Does any1 here know what the LG warranty is like in the UK??

Cheers!

[LG Optimus 2x] TAZcg:
Well, no need for me to worry about his anymore. I decided to exchange the LG Optimus 2x to a Nexus S ...yay!! No need to pull my hair out.

[LG Optimus 2x] sander-m:
I am also experiencing this issue. It does not happen to me on stock 10d rom. (at least for 2 weeks) but on CM7 (build 112), thanatos (swiftextreme kernel) and modaco Gr2 alpha the phone shuts down every time I charge the phone. I have also switched to a 3rd party charger but it doesn't solve the problem?

Is this a kernel problem?

With Modaco froyo for example I have 0 sleep of deaths. stock 10c cause several SOD's, but on 10d I have no problems. CM7 EVERY time I charge the phone it shuts down and the only way to boot is by pulling the battery out and in and start.
[LG Optimus 2x] davew:
This is the kind of experience that makes me think twice about installing custom ROMs right now.

I think your best bet might be to smartflash your phone back to stock, and make a warranty claim for a replacement. I'm in the same position, hopefully I'll get a working phone back soon enough and then I'll be able to enjoy some custom rom fun.
[LG Optimus 2x] sander-m:
I'm now going to flash back to stock 10D and hope for good results. I really don't like to send this phone back for a replacement but it might be necessary if the problem remains.
[LG Optimus 2x] orlox:
all my problems stopped with 10c 622bb. I am with 10d 725bb now and stoll now problems.
[LG Optimus 2x] sebzero:
problem solved?

I used to have this problem as well, up to baseband 10d.

Monday I got bored and finally decided to root the phone and still had the problem. The main reason to root my phone was because I wanted to test autokiller memory optimizer and I really like that app, but more interesting, I haven't had any freezes anymore.

Could it be that it's a software issue caused when accessing the memory?

I'd just say try for yourself ;)
[LG Optimus 2x] davew:
My best guess is that there are at least two manufacturing runs of the 2x out there in the wild. One had a hardware fault that cannot be rectified no matter what firmware you put on it. The other batch doesn't have the hardware fault, but firmware prior to v10d or thereabouts (the version numbering system is not consistent from region to region) gives similar problems.

So if you have a phone from the "problem" batch, and no firmware you've ever tried sorts out the phone, send it for repair. If you have a phone from a later batch, update your firmware to the latest stock version and baseband for your region and you should be golden.

As I say, this is just speculation, informed guess, call it what you like.
[LG Optimus 2x] rc_bdo:
Its not a software issue, its hardware, go to LG service centre and they will replace it with a new machine, Mine no longer have BSOD and upgraded to V10e.

Its been 2 month since the machine replacement and the phone works great now.
[LG Optimus 2x] davew:
Unfortunately my local LG ASC was useless, all they did was hard reset the phone and send it back. Three weeks and a lot of hassle completely wasted. I've sent my O2X back for a refund and I will never, ever buy anything, not even a fridge magnet, from LG ever, ever again.
[LG Optimus 2x] luka2858:

freeze/shutoff problem still not fixed

Gingerbread still not released

No, gingerbread will not fix this problem, nothing will.

No, it does not have USB host support

Take my advice, Ive gone through several of these O2x during the last 8 months, and sad to say LG has failed big time. Get a Samsung SGSII instead, like most previous O2x customers do. Its a different world, they just work. I still have 2 O2x lying in my drawer, none of them work. They still freeze several times a day if used, cant even sell them at a reasonable price cause noone wants to buy this crap after all the press about these problems. LG does nothing to solve the problems, and any updates just get postponed all the time.

Save yourself alot of hardship and avoid this phone like a bad disease.

I bought 2 on the very first release date some 8 months ago or so

Both have had system board replaced 2 times, and the handsets themselves replaced 2 times.

The latest replacement to new handsets was 1 month ago, both of these are still freezing up several times a day especially when my son streams youtube video over 3g - only a battery pull can wake them up again.
