[Guide]LG G2 screen replacement

This video is the how to on what you need to do in order to disassemble the G2 in order to remove the screen. There is a link provided for the reassembly in The video.
I was able to pick up a screen/digitizer/LCD from amazon for about 120. Make sure to pay attention to where it ships from. A lot of the sellers ship them from Asia and they take up to a month to come in. Mine came out of New York. Also the screen assemblies from OEM come with a kit with jeweler's screwdrivers and plastic pry devices in order to disassemble the phone or at least mine did.
Last in the video he uses a heat gun at some points. I did not need one throughout any of the process but may make it easier for you.
All in all I took me about an hour and a half to swap my screen out. Works like a charm.

Hi there. I just broke my digitizer, but the screen is fine. I read somewhere that you have to replace them both because they are glued together, do you know if this is true? I have a heat gun if that is needed to separate them. I would just like to purchase a digitizer only and replace that, to save about $60+.

yes you can get digitizer but if you make the slightest mistake you end up breaking the lcd and will have to replace them both

Ok thanks, I am leaning toward taking it to a local repair shop and letting them do it. Price be damned!

yea plus my advice is from personal experience I had already tried it and ended up paying more since I had to buy the lcd plus digitizer

Not sure what the price would be to just replace screen/digitizer. the part would run about 30 bucks, just not sure what a repair shop would charge for labor. If its over 150 though i would opt the DIY method as it is simple to do if you get a screen/digitizer/lcd all in one. I did it for 120 and some change. Mine also came with a tool kit in order to dismanlte the phone.

hi friend, i have a LG VS980 Verizon, Is it the same part for vs980 and d80x? in my country im only able to get D80x version of screen and sellers are not sure if the parts are compatible, I have seen several videos and pictures of the online stores of spare parts, and at first glance are the same connectors.

I couldn't vouch for that. A good place to start though might be to compare specs of each phone, V980 to D80X, specifically the display properties. Not sure but there may be a good breakdown out there of what the specs are for each, not just a dimension and pixel count.

they are the same Verizon can change buttons and add stuff to back cover but they cannot change all of phone hardware/parts

Sprint to Verizon (motherboard swap?)

Question In summary:
Has anyone swapped their Verizon motherboard to a sprint model or vise versa and got it to work?
In detail:
Ok so, got my Verizon note 4 wet few weeks back. Didn't realize how wet it got and started it back up too soon, worked fine for about 5 min and then the screen shorted out. After completely drying it still boots, still freaks out from all the messages etc pooring in from it being off, was also able to access from my computer to pull off data.
I was able to locate a mint condition sprint version for a reasonable price, my theory is that I can simply swap my mobo from the old phone to the new sprint one and be good to go. I tore it apart last night and soaked it in rubbing alcohol to clean off any remaining deposits,I'm trying to source a sonic cleaner to do a better job if possible.
Any reason this won't work? Any possibility I could damage the good screen with a bad mobo from the Verizon? Anything else you can think of that I haven't addressed? I suppose I could sell the sprint version and fund an actual Verizon replacement from the sale but if this will work...

bump, looks like i might be the guinea pig...

Why not just get the Sprint phone, unlock it, and just use it on Verizon????
You'll be buying a mint condition phone anyway. Why tear it apart when you can use it on Verizon if unlocked?

I was under the impression that sprint and Verizon run different tech for their networks. If they don't, or if the phone has the hardware to use either, then yes, I'd much prefer to unlock it and go that route. If anyone can confirm that'd be great. I had done a bit of googling on that earlier but everything I found basically said they were not compatible.

Ok, I just researched it and found 2 things:
1) Verizon won't activate any device not bought from Verizon. (According to a forum)
2) Sprint and Verizon use different IMEI types, so one carrier's phone won't work on the other's network.
So I guess you can't actually just use the new phone.
This now brings up the question of how swapping the mobo will affect the IMEI. If using a Sprint mobo will make the phone now have a Sprint IMEI, then you won't be able to get the fixed phone to register on the Verizon network. And, Verizon may not register the device anyway.

Screen burn in or broken screen?

Hey all,
My friend just got a brand new galaxy s4 on Friday the 8th of January this year. She's had multiple software problems on lollipop, many force closes and heavy battery drain for the last few days. It's been plagued with issues. Now her screen is messing up, there's a clear line of some sort of app imprinted on the screen, she also says a time has been imprinted on the screen where it shows in the notification bar. Is her phone just a defect or is it just lollipop?
Last night she dropped it from about one and a half feet onto the screen, its got a tempered glass screen protector on it but now the screen has those imprints. I've attached the photo. Looks to me like burn in but she said she thinks she noticed it since she dropped it. Surely the S4 couldnt be that bad? What do you think of it? Any way to fix it?
Thanks,
Lachy

Are you sure it's a genuine phone? I doubt new phone would have such problems.

If it has a download mode (not just recovery), it should be a real S4.

Humm.....
Looks like a refurbished or used phone..... Burn-ins shouldn't appear this fast, as a S4 owner myself I didn't notice any burn-in in my 2 year old phone.
Try installing Phone INFO from Play Store and do a refurbish test or something like that in the menu section.

Hmm, all of the features are working, air view, infared sender etc. Runs pretty smooth, feels like a legit phone. No scratches or anything. I'll get her to get that app. Thanks!
EDIT: Has a download mode

I agree with you, surely something like this couldn't have been from a drop at two feet though? I'll get her to download that app you mentioned and report back

News
Okay hey everyone got some things to report back. The phone has a download mode, so it is a legit version. I got her to download the phone info app and I have pasted the screenshots below. It was bought at an electronics expo in Singapore advertised as a new Galaxy S4 GT-i9500 for $239. Something weird I have found is that the samsung info app states it is a SPH-L720T, which after I googled saw it was the Sprint LTE version. All of the other apps, including about phone in settings state it is the GT-i9500. One thing to note is that she is on a holiday in Singapore, but has a prepaid card from Starhub (I don't think the LTE bands match up though) and is apparently getting 4g on her phone (tried switching to 3g but to no avail), but doesn't want to check because she'll waste her credit. I find this weird because the apps state different things. It didn't look refurbished to me and I didn't notice the streaks across the lines. What do you guys make of this?
http://imgur.com/a/9YO2l
Thanks heaps!

EDIT: She noticed three more lines running through the screen. But now they're more obvious, looks like it's getting worse. Not a great experience for a brand new phone
SECOND EDIT: Her sisters phone also has the line in the middle, albeit much much feinter. Are both of these defective?

It is definately refurbished.
It probably has been repaired with parts from different S4 models and then sold as refurbished. That's why there is no match between the phone model info. This might also be the reason for the various problems.
Edit: If it really is brand new she can take it back to the store for warranty service. Every store offers warranty with brand new products. Refurbished phones also have some sort of warranty I think.
Edit2: The screen might need to be replaced. As for the app problems, check the phone model in download mode and flash a rom (stock rom) for that model. Apps can be fooled, download mode not so easily.

It was sold as brand new. Her sisters states black as the colour in that phone info app, when it is white. And also has 4g. But unlike this one the model number is GT-i9500. On the box I remember it said American version only, for use with american sims only. But then it worked with the one from Singapore. This is super weird :/

Do they have warranty? If yes, send the phones to service. If no, the store is not legit and they got hustled.
As I said, brand new products have a warranty, generally for a 2 year period.

The L720 model is a I9505 from Sprint.
I doubt Samsung would mix parts together..
I'm telling you, those phones are clearly not factory new. They have been repaired with spare parts from various S4 models.

Looks about right. Her sisters phone was also meant to be a GT-i9500 but by the IMEI it says it's a SGH-1337 which is the AT&T 4G LTE. I guess both of these phones were false advertised as the GT-i9500 (even on the box) and as brand new. Looking like they're definitely replaced parts or something?

Yea. The original phones might have had their screen broken so they took the motherboards and put them into other frames. I like to call them frankenphones.
I don't think Samsung would do that. So somebody else repaired them. Factory new phones don't come with mixed parts and used screens.

Yap, agree with @GDReaper , they just assembled those phones with parts that they could find and didn't at least try to flash a new firmware for Singapore before they sell it. And that product name... I think the nomenclature used is jflte for all Qualcom variants and the two or three last words are to specify which like jfltexx for international LTE(GT-i9505) jflteatt for AT&T(SGH-I337) but jfltefreshspr... of which spr is code for Sprint.... but that fresh which means refreshed?????
In my opinion give back those phones and order a refund if possible, if not you'll have to change those screens which where I'm living now still has a nasty price of 130 euro (the touchscreen and the AMOLED one are bundled together) Which will cost almost the cost of the phone....
EDIT1: They probably grabbed some i9500 box or made some with cardboard and covered it with printed exterior and also replaced the broken safety anti-tamper seals for them to look authentic and genuine which they are not.
Other thing is that they just cosmetically replaced those models with i9500, that like i said before they didn't even try to flash a new firmware as they are afraid bricking those devices.

My mother has an S3 which also has the same kind of burn in problems you describe, so clearly this is a problem with Samsung screens, I have never seen this on any other screen except my pals old plasma flat-screen TV....

Well. It's not Samsung's fault it's the natural degradation of AMOLED matrix due to heavy use or prolongued static image display.

The drop did it. I know this because someone I know has a same problem, and I saw this a several times. Also sadly, there is no way to fix this problem ;(

Fixing back panel crack with JOD

Does anyone have experience with a cracked back panel and being on JOD? I am thinking about attempting to replace it but, it does have the IMEI listed. Does anyone know of a back case manufacturer that can add the IMEI as well? If all else fails I am pretty good with the guys at my local T-Mobile, I may just try to convince them to say it happened at trade in, or put like a D-Brand Skin on it and see if I can get it past them that way.:laugh:
Thanks in advance

I don't have experience with JOD particularly, but would like to caution you against trying trickery that you mentioned. Even if you put a skin, they'll remove it to try and put this in the refurbished stock, see the crack and charge you for repairs. As for the IMEI, it really doesn't matter. If I'm not mistaken, it is just a sticker. When I got my phone back after a Samsung repair, it was removed anyways.
And finally, regarding your idea about getting local reps to lie that all was ok and stating it was damaged in transit, we do not promote such deception in xda. But it is up to you if you want to go ahead and try it out. As this is definitely a physical damage, better own up to it and pay for it. Since it is for the back panel, it'll probably be around $70 (directly from Samsung, front glass is $270). It might be a lot cheaper if repaired somewhere else.
Sincere apologies if I sound like a douche, but that's the best advice I can give you.

Thank you for the advice, the IMEI is apart of the back panel not just the sticker thing, but actually apart of the back. I've found back panels on Amazon for like $10, maybe I will call Samsung and see if the repaired versions have the IMEI.
This was very helpful.

Interesting. I wonder why mine doesn't have it anymore. TBH, I never noticed it before.

Just get it fixed, t-mobile(and almost any phone company I've deal with) will accept most of these phones as long as it doesnt show physical damage. I used to work for a phone repair shop in NYC and they(literally the guys at the T-Mo/Sprint/ATT stores) would send guys over to fix their phone before they would accept it as a trade in.

they include imei sticker int he box for reasons like this.
The imei is in the phone harness.
phone app *#06#
So when they do a trade in or any work on your phone. All they need to do is put in that code and it will being up th imei and they can move on.
But since it crack and you try the jump. They will either charge you the insurance claim price/ not give you the full amount for it. leaving you to pay the different before you get the new phone
Other then that it doesnt matter if the imei on the back is gone. the phone will be refub once it leaves your hands.

Broke mine too .. $60 at local repair shop

Very interesting, I have found backs on Amazon for like $10 bucks. Not sure if they're really that great or not but, I will give that a try. Worst case they turn me down and I am stuck with the phone for a couple years.

As long as they're glass and has the Samsung logo on it, it'll be fine. Make sure you also get some decent double sided adhesives for it, or get the specific adhesives cutout for the S7E that you can just slap on. I usually use redline tapes, they're slightly better than scor-tapes imo.

Just replace it. Amazon and eBay have it for $25-$30. All you need is a blow dryer.

V20 Motherboard Swap

Ok. Here's the situation. I own 2 V20s (buy one get one at launch).
One was never used. The other is my primary daily driver phone. Well... I dropped it and the screen is dead, but the motherboard is in perfect condition and still works.
Here's my question, can I simply just take my daily driver motherboard and swap it into my secondary V20 that was never used? Basically put my everyday motherboard into the phone casing from the never used V20? Will there be any complications (ESN, camera, force closes, etc)?
And if that's not possible, can a direct nand backup be flashed over without complication?
I ask this because I have done numerous hours of custom development for my own personal use that I REFUSE to loose.
Thank you so much to whomever can answer and help me.
EDIT
The casing on the daily phone was also slightly damaged, hence why I'm trying to do a full swap and not just the LCD.

PREMATURE BUMP
From the teardown videos I've watched, it appears that the radio/modem and motherboard are all one piece. So that will eliminate the ESN issues. Anything else that I should worry about?

I'm confused by the numerous hours of development statement in the same post as can I swap identical mother boards or do a NAND backup from one device to a identical device. Not trying or meaning to be rude just think about your post.....
The serial number will be the only difference regardless.
Personal choice. NAND backup then restore to the other device, unless you are 100% sure there is nothing wrong with the current motherboard, in which hot swap.
I'm assuming they are identical since it was BOGO as you stated. Don't know any place that would offer that and say give you a H918 V20 with a LS 997 V20.

I did same thing. I cracked my main screen on T-Mobile variant. I bought a bootlooped V10 on eBay that was Verizon. All parts in good condition, just a dead phone. Took them both apart and placed the tmobile motherboard into the verzon model. All went easy as pie. Only negative is that the one I picked up has lousy image retention. But otherwise perfect condition screen cosmetically.

I think you will be fine but i recommend swapping over as many parts as possible to the new V20 or just take the screen off the new V20 and swap it with the cracked one. That's the safest option imo.

Thanks guys. Much appreciated. I know some phones don't like MoBo swaps unless you swap almost all the other parts also (S4 anyone?).
@DarkestSpawn Only reason I suggested the MoBo is because I was not sure if a NAND backup between phones would actually work correctly, considering different serial numbers. Never had attempted that before. Also, I do not have access to a PC right now. So the NAND backup would take some time. Trying for no downtime, hence the MoBo idea.

Believe it or not, my local verizon wireless had an amazing offer going on. They paid all termination fees and gave two free phones if you had good credit and switch service that day (one day flash sale), so I swapped service and got a Pixel XL instead. Unlimited photo storage ftw. :highfive:
