Original Motherboard - G3 Accessories

I need to buy a new motherboard for my LG G3 D855 because I "fried" my old one trying to fix wifi problems.
Does anybody know some place for extra parts, that isn't too expensive or oficially from LG? Thank you.

Honestly, you're better off just buying a new phone. Logic boards are usually $100 and over and it's not guaranteed that the board won't have issues.
You can try looking on eBay though.

I bought a secondhand g3 with a broken screen for 35 euros. Switched motherboard and everything was working again. So maybe this is an option.

Where did you buy it?
I did the same, bought a lg g3 with a broken screen, from a local ad site. Switched motherboards and everything was fine until I tried to make a call as it losses the network and does not allow me to make or receive calls. Oddly enough I have 4g data and everything else works.
When I switch network to only 2G or only 3G the phone losses the network and I have no data. If I put "automatically switch between 2G, 3G, 4G" I have 4G data can not make or receive calls.
I installed xposed and imei changer thinking that I had bought a stolen phone, changed the imei number and still no network.
If anybody could help I´d be grateful.

Hi Fluffier,
I have same issue as you: https://forum.xda-developers.com/lg-g3/help/brutal-signal-attenuation-d855-t3586931
It must be motherboard. Sorry...
In addition this easter days it added bootloop to the list of failures... (It only works connected with a 2A adapter + only LTE and Wifi).
After some deliberation I've just bought a V20 on china.
Andreu,

I had to do almost this same thing. I bought working phone with cracked screen and I replaced my mainboard (with no signal issue) with 'new' one. On stock (directly from kdz) I got message from system that there is a problem with mcc number. Exactly the same as this: https://forum.xda-developers.com/showpost.php?p=57630582&postcount=443.
Apart from this, everything works great and I really recommend that method as a second life to any phone

Yes, definitely yes. If you do it, your phone will not be us990 anymore. It will be d855
All you have to remember is you could receive this same warning as I mentioned in previous post, but it shouldn't pop-up in any moded ROM.
For 100% it is not active in Fulmcs 6.9 and any Nougat ROMs.

If you bought main board for d855 you should flash kdz for d855, not anything different.

I did nott buy the d855,,i unbricked my us990. It is now in download mode..not letting me flash us990 kdz. It stops at 2%

Hmm, I bricked mine a few times - it's really easy with this phone and for no reason. I tried different flash programs/DLL versions, then the COM ports switched on me and it was also very dependent on the USB port on the computer - change things around. Eventually it should work. And then if you have it open there's also the Qualcomm recovery where you can go into a download mode and directly load the extracted binaries from the tot file. That worked no problem on mine on first try. I didn't even flash the whole thing - like data and system, just whatever it needed to boot - the small partitions I suspected of being corrupted.

In 2020, it's worth it !
Hi everyone, quick update on 2020, regarding whether or not it's worth buying a new Lg G3 motherboard :
For the context, I received my phone from a friend of mine, which change phones in the mean time because of its battery issues, but changing the battery solved everything. At some point, last year, my G3 dropped into the sea -_-') but I did not want to part with it and I had to to change most of the components.
I managed to get first a new motherboard, then a new back camera, a new prebuilt LCD + touchscreen frame, a new jack plug (being broken by default), a new camera lens, a new flex cable for the buttons and a new antenna for less than 65$ on AliExpress (mind you, the D855 2GB/32GB motherboard was 28.63$ and the screen was 20.99$)
Honestly, my only complaint is the amount of memory (2GB in a little on the light side) but this phone is awesome ! It's super cheap and easy to repair, and I actually bought spares for a later time. If you have a dead G3 at home, I think it's worth repairing it

Hi, I found my old G3 and wanna try to revive it. I was wondering if chinese motherboards are reliable. I read about someone saying that IMEI on those motherboards is overwrited to look like other models, basically a "frankenstein" motherboard. Can you give me your feedback. Thanks

Hi guys, first of all, sorry for my english, i hope you understand me.
My phone doesnt turn on at all after i removed the battery because it was frozen after installing this rom http://forum.xda-developers.com/showthread.php?t=2468880. it even doesnt charge.
I already tried all fllashing guides with no success, actually i got enter in fastboot mode and sw upgrade mode, but after 1 or a bit more minute it turns off.
I tried to flash the x-loader and u-boot using the lelus script, but i get the errors shown in the pictures.

The "Remote Partition doesn't exist" error in the second output log that you posted, indicates that you have a hardware problem/fried Emmc. I don't know of any solution to fix that other than, a warrant claim through LG or possibly having it repaired at a service center with an Octopus Box, which does support the LG L9.

Ok, so now my phone is a stone, warrant claim will not work for me. I am thinking on buying a phone for replacement on ebay and change the board, that should bring my phone alive again isnt ? My phone also was sim unlocked, if the board of the phone replacement also is unlocked, it will on my phone ?
Do you guys know if the board of the P769 is compatible with other L9 models ?

There are so many L9 variants... If your going to purchase a device and disassemble it, then swap parts into you existing phone, I would only recommend trying to replace the mother board from an exact same model, P769. It's definitely possible that the MS769 (metropcs version) would work, as it's identically the same phone.
If the new phone is SIM unlocked, then Yes... Technically after repairing your L9, it should be SIM unlocked as well.
Out of curiosity... If your buying a new/used, SIM unlocked L9 off of eBay or swappa, then why not just use that new phone, instead of tearing it down and your old L9 down and swapping/replacing the mother boards?

Hi xdrc45, since i only need to replace the board, im thinking buy one of those that has broken screen or poor fisical condition but working complete, those are cheaper

Lol.. OK, now that makes sense. I was just curious and thought I'd ask. I haven't looked, but it seems like you could get them pretty cheap in that condition... Especially since a new one or fully working used one, go for a decent price to begin with.
If your looking at them on eBay you might want to also check out Swappa. There's a link to it up above in the XDA header and a lot of the devices on there are from different android forums members.

Update Problem

Hello All!
I am fairly new to the site, and not too tech savvy, but I'm having some problems with my Verizon LG V10 I bought about 3 months ago.
I bought the unit from eBay for 300 dollars in new condition (a steal if you ask me), and it's been working great, but I have been having issues updating my phone.
I am aware that Marshmallow is out for the V10 on Verizon, yet whenever I click on check for updates, it always says no upgrade is available.
As most of you probably know, Verizon phones are unlocked, and I am using an H20 sim card, putting the phone in international mode. My question is that I'm wondering if that is the problem, or is there something else?
Thanks for your help
I thought all the V10's shipped with Marshmallow.

They actually don't.
I bought this one off of ebay, and it came with 5.1.1
I even tried the Verizon Software Updater, and thought I had it, only to find out that nothing changed, I really want to get a hold of the battery life optimization in Marshmallow
You won't get Verizon updates on another network or outside North America.
Download the kdz and upgrade it yourself
please provide kdz file working link, nowhere i can find it.

motherboard replacement

dont ask me how but today i burned my internal memory chip in the motherboard, it was real hot like 140-160 degrees F for 15 mins or so
now i need to replace the motherboard and the thing is my phone is h960ay model, its not a common model and its hard to find motherboards for this model. i found some motherboards of the same phone but in a different model
so can i fit not the same model motherboard to my h960ay? (H901 or VS990 motherboard to h960ay?)

yes you can fit all V10 variants motherboard into your V10 chassis. that is not a problem.
Does the logic board have your IMEI/ESN on it? I was thinking about this the other day when I was looking for one for a different phone. And if so that could give you a issue with your carrier unless it's unlocked.
Just a thought.

There are V10 unlocked motherboards shipped from China available on eBay.com and aliexpress. They are cheaper on aliexpress. Mine is bricked too after a marshmallow update for h901. My v10 is h901 with vs990 motherboard, which I didn't know about till after it bricked. I am considering buying one of those unlocked motherboards too. I am waiting for someone to confirm if it's advisable buying from these sellers and whether they would directly work after fitting them in my phone chassis without any further updates or tweaks.

i've just got my motherboard replaced at a non-LG repair shop yesterday and when i got home i realized the memory was actually new - previously i was on android nougat - now this is android oreo and there is no IMEI on it. *#06# shows 2 line of 0 (Dual SIM). when i try to get it to upgrade via LG Bridge, i think it failed due to no valid IMEI and when i tried to do OTA, it says my phone is not activated.
I've tried entering my previous IMEI via hidden menu, and i got the LG bridge to recognize the device and found the nougat update but after it tries to download and update the phone, it failed (at 1%). Does anyone have a solution on how i can get things back together to update back to Nougat?
Thanks!

There's no Oreo for LG V10, so probably you are saying you are on Marshmallow and now you are on Nougat.
And if there's no IMEI for sure the motherboard is refurbished and soon you will have problems with it, almost every person who buy "new" motherboards or replace them with ebay ones someday will get again bootloops and so on.
use UPPERCUT to try reflash the phone firmware, if this doesnt work then you are screwed.

So you reckon getting mainboards replaced officially by LG should be exempted from the bootloop issue am I understanding this correct?

is not 100% guarantee but a motherboard replaced by LG is more secure to not have bootloop than the ebay sold ones.
Strange is my V10 is still alive after 2 years and 3 months, its my daily driver and i use and abuse from it it never die, im feeling lucky in this wole story.

Verizon activation help

Hey everyone,
So I did this on my personal phones a few years ago, and even my MIL's phone (Mother in law). I cut the SIM card in those cases, and plugged it into the new phone, and all worked just fine for the most part (MIL phone is having issues, maybe because I did a poor job of the manual cutting).
Anyway, now I'm on the FIL's phone (father in law). I activated a brand new phone on an old Droid Turbo phone, and it's working fine there. I moved the SIM to the new V30 (originally US998) and it's not registering on the network. I wonder if I just did this too quickly (I didn't let the SIM "sit" on the Turbo for very long)... which is why I moved it back there now. I figure I should let it sit there for a bit, and then try again?
Any ideas on what else I can try? Basically, the V30 was saying it saw the phone number, but it said IMS not registered... any ideas on how we can fix that? The *#*#4636#*#* doesn't work on the LG phones... I've used Shortcut Master before to register VOLTE, but I'm out of my realm here because the SIM is not registering the phone, so that's not an APN or VOLTE issue.
Any help or ideas are appreciated... thank you!
EDIT: One more comment. I'm hoping to go to VZ tomorrow and get a new card for the MIL phone. In order to activate that SIM, I'll have to activate that SIM on the Turbo, otherwise VZ will throw a hissyfit for the mismatched IMEI. So, I'm hoping I can repeat this process with the new SIM on that phone... I'm hoping we don't have this problem there too.
Ugh, VZ, why do you suck so bad.
I've been down a similar path. I own the same phones. You didn't mention which rom is on the v30 but suspect it is a us998. I, too, had some difficulties getting my v30 to work properly on the vz network. The turbo with a stock verizon rom came in handy to set vz account/network options.
1) Install stock MM rom on the turbo. The debloated one by computer_freak works great. You can get it here: https://forum.xda-developers.com/dr.../computerfreek274mm1-0-android-6-0-1-t3503634
2) Pop the vz sim in the turbo
3) Activate: HD calling, visual voicemail in the dialer, and set up volte. I don't remember if vowifi is an option on the turbo. If it is, then turn it on, too.
4) Put sim in the v30 and enjoy.
Another and possibly better option to get the sim and phone working together is to cross-flash to the verizon vs996 rom. The advantage of the vs996 rom is that vowifi and visual voicemail will work. I've never succeeded in getting vowifi provisioned on the us998 open market rom. That is some vz-lg shennanigan.
I second what cmrntnnr stated above and emphasize flashing VS996 on the V30. Big Red can still tell what your phone actually is by its IMEI. My V30 originally was a LS998. I also had to manually set the MMS settings to keep Verizon firmware from thinking it is a Sprint phone. Please see this if you have issues with MMS. https://forum.xda-developers.com/lg-v30/how-to/guide-how-fixed-mms-settings-flashable-t3856109
Yes, I am on VS996 for this phone. And I did this very same process on my personal phones, but for some reason the new V30 isn't accepting the card, which is why I asked.
Yes, I know VZ can see it's not a true VS996. Thanks for the link to fix MMS, but I wanted to fix the lack of connection first before working on the other things.
I will try it again (maybe I swapped SIMs "too fast" for the VZ network to accept it or something?... though I swapped it back to the FIL's LG G3 with no issues... so very weird, and annoying).
All that said, we may just get them "true" VS996s instead, because that way they can still get help from VZ when they aren't nearby (they live in FL, while I'm in CT). It's not that VZ can't help, it's just that they won't... that's what pisses me off...
EDIT: Again, the question is, why isn't this phone connecting? It's seeing the phone number, sees the SIM fine, just wouldn't connect to the network and kept saying it wasn't registered... didn't know if there was a trick I could do or something to force it (probably not, as it may be a VZ-server thing, but who knows).

Try the Verizon secret menu and play around with the settings: *#*#4636#*#* or LG Secret Menu (must use stock LG dialer and not Google dialer): *#546368#*996#

Awesome, this is what I was looking for.
I tried getting to the secret menu, but it never seems to work (even on stock dialer). When I did the VOLTE fix on my phone, I had to use ShortcutMaster.
Regardless, once there, what should I look for/do?
I have the phone back in-hand now. As before, the SIM works fine in the old phone (LG G3) but it still doesn't connect with the new V30 (on VS996). Note, I did use a SIM adapter to put it into the old phone (it uses micro-SIM sized cards). And, again, it's seeing the correct phone number, but it's not connecting to the network. Network mode is set to global (default) and toggling that around doesn't help.
I also got ShortcutMasterLite to let me into the 4636 menu, but I don't see anything wrong in there either. Not sure how to get this phone working?!
I'm now wondering if it's just a defective phone? I'm seeing signal levels that match my other phone, but still, who knows? Maybe the radio is having issues or something... I suppose I could try my personal SIM instead, or something?
So no help.... not that I'm blaming anyone.
Problem is that the Ebay listing said that this phone will NOT work on VZ, etc. So, I don't have much hope of the seller helping me, even though it's a completely false statement, as we all know. So, I may have to convert back to US998 and then test with an ATT SIM to prove to the seller that this is a defective phone. Anyone have any ideas on how I could do this? For example, would anyone be willing to meet me somewhere (I live in CT, but I can drive wherever in New England) to try your SIM on this phone? I figure, if it doesn't work, then I have proof that it's defective. Otherwise, I don't think the seller is going to even try to help.
Anyone willing to throw me a bone here with a little help? Or anyone have other ideas on how I can test? Does ATT have a prepaid thing that I could try for a month (low cost) to prove it out or something? I know far too little about ATT...

Yes.
They have a Prepaid minutes plan they don't like to advertise.
https://www.att.com/buy/wireless/prepaid/devicesandplans
When you put in your IMEI to the AT&T Prepaid webpage put all zeroes instead of your real IMEI and it will show you all plans, not just what they want to sell you.
Also AT&T Prepaid uses same same regular AT&T SIM cards. Don't let them sell you some special SIM card.
I'd have reached out to help if I had any ideas. Your hypothesis that it is broken seems reasonable and so does flashing it to US998 as verification.
Getting on the ATT network without ATT is a breeze. Cruise down to Walmart and pick up a StraightTalk kit for $30-50. It will have sims for VZ, ATT, and TM so you can choose whichever network is best for you. They're good to have around.

Hey everyone,
So I did this on my personal phones a few years ago, and even my MIL's phone (Mother in law). I cut the SIM card in those cases, and plugged it into the new phone, and all worked just fine for the most part (MIL phone is having issues, maybe because I did a poor job of the manual cutting).
Anyway, now I'm on the FIL's phone (father in law). I activated a brand new phone on an old Droid Turbo phone, and it's working fine there. I moved the SIM to the new V30 (originally US998) and it's not registering on the network. I wonder if I just did this too quickly (I didn't let the SIM "sit" on the Turbo for very long)... which is why I moved it back there now. I figure I should let it sit there for a bit, and then try again?
Any ideas on what else I can try? Basically, the V30 was saying it saw the phone number, but it said IMS not registered... any ideas on how we can fix that? The *#*#4636#*#* doesn't work on the LG phones... I've used Shortcut Master before to register VOLTE, but I'm out of my realm here because the SIM is not registering the phone, so that's not an APN or VOLTE issue.
Any help or ideas are appreciated... thank you!
EDIT: One more comment. I'm hoping to go to VZ tomorrow and get a new card for the MIL phone. In order to activate that SIM, I'll have to activate that SIM on the Turbo, otherwise VZ will throw a hissyfit for the mismatched IMEI. So, I'm hoping I can repeat this process with the new SIM on that phone... I'm hoping we don't have this problem there too.
Ugh, VZ, why do you suck so bad.

So no help.... not that I'm blaming anyone.
Problem is that the Ebay listing said that this phone will NOT work on VZ, etc. So, I don't have much hope of the seller helping me, even though it's a completely false statement, as we all know. So, I may have to convert back to US998 and then test with an ATT SIM to prove to the seller that this is a defective phone. Anyone have any ideas on how I could do this? For example, would anyone be willing to meet me somewhere (I live in CT, but I can drive wherever in New England) to try your SIM on this phone?

Which VS996 version did you flash? Nougat, Oreo, Pie? Try Nougat as it's the most reliable VS996. US998 Nougat should read VZW sim also.
Thanks for the tips on ATT and Straight Talk. I think I will have to try that, but first I'm going to try to get the ebay seller to "promise" me that if I go through this, that they'll actually do something to help. Otherwise I'm just spending money for no reason.
As for the VS996, it was Oreo, the same version I'm using on my personal phones, and the other V30 - you may recall that the MIL's phone is functioning, but the FIL's is the one that is just not connecting at all... I always get 0-bars with the "x" on that one. That's what I'm trying to fix here...
Again, thanks for the tips, let's see what I can get done here with all your excellent help!
Ok, so the debacle is over. I wanted to provide a little info for what ended up happening, and what I learned.
Longer story short, I was able to get the first H931 phone working fine with no issues. It runs on VZ towers on VS996 and US998 (I created a video for the latter, to prove it to myself and the warranty company). The second one refused to work on VZ, and I felt it had issues on GSM carriers as well (I tested Mint Mobile, as it was free). This phone was sent for repair to a warranty company that the ebay seller offered to pay for.
The warranty company tried to get that phone to work on VZ, but couldn't. They kept telling me that this was "not possible" when, as we all know, it most certainly is. Bottom line, something is defective with that phone, as I suspected. However, I expect no one is going to bother to repair it so it will likely show up on Ebay or wherever again as an H931 (or US998) with this problem persisting. I figure another buyer may not notice it, as long as they don't use VZ....
But, the moral here is that you should be careful when you buy the device, to ensure that the seller doesn't put text on their post saying that it won't work on other carriers. I was afraid of this text, but I went forward anyway as I (and we) know this works fine. I also proved it on one phone (the first one). However, if the seller says this, then they won't necessarily take any steps to help fix the issue if there is a problem anyway. I got lucky and my seller at least provided me with the warranty card, which helped a lot.
The warranty company did do everything they could to help. I have to commend them on that, as we are hacking the phone, after all... but Jose was very understanding and helpful regardless. For this reason, I really recommend their service... they are CPS Warranty and they can be found at https://www.cpscentral.com/ Again, they could have blown me off, but they didn't... and after all that, they offered a settlement to pay be back for the phone since they couldn't get it working on VZ. I'm out a little money, but the settlement was fair, so I can't complain.
So, while this all works, we do need to be careful, as some devices are defective and hard to detect for this type of issue.

LG V60 retail demo unit hard brick recovery

Hi all,
I have bought a retail demo unit from ebay and it worked fine. I was succesfull in removing the "Retail Mode" app, but then stupid me wanted to experiment more.
I have experience flashing V50 so I have tried LGUP with retail stock firmwares for US TMO and Verizon. It did not work. Then I tried lgup_cmd and it started cross-flashing the TMO firmware.
At around 80% the screen went completely black but the firmware flash ended successfully according to the tool.
Now the phone does not switch on at all and does not react to USB charger.
Is there any chance to unbrick?
I feel for you. I have a really nice Demo Unit v60 from eBay as well and as much as I like it, the 50% battery limit sucks rocks. Hope you can figure out a way to get it back in order

Hi, bro. Could you please tell me what it is different from a normal V60? Is it only no signal and battery limit? I'm planning on buying one but I'd like to be sure. Thanks in advance.
As far as I know only that. 50% charging can be worked around by charging switched off.

I've never found a way to get around the 50% charging capacity though that would make everything far better. I have found a way to rid retail mode and get into security settings, but charging block still remains. No fingerprint sensor, haven't gotten stylus support to work, dual screen DOES work though. Also haven't gotten a software update since March 1, though most carrier devices have.
I use mine as a WiFi device and enjoy it minus the 50% battery.

Hi I recently bricked my Lg V60 retail phone trying to flash in a stock rom. Did you manage to get yours sorted out?
Unbrick will be possible when firehose becomes available

No, if your phone does not switch on then there is no chance to recover it.

If you charge while in recovery mode it will charge to full. Definitely a ***** to do it every time you want a full charge but it works.
Has anyone gotten the finger print reader to work on a demo unit? Or have you been able to enable pin for unlock? All options are greyed out under lock screen for me except swipe and none.
to all who wonder about this after demo hack fingerprint reader issue i want to just throw my guess out there and say this i a total guess on my part but possibly lg put that as a hardware trip if you mess with retail mode. there was a different model that disabled the rear camera if you messed with retail mode. if you ask me this is a bit less tragic way to go. somehow they have the ability to make life miserable for hackers who try to circumvent stupid things they do.
i don't know about v60 but I got a velvet live demo from eBay for 80 USD
and I flashed the Korean stock ROM android 11 July update with LG flash tool version 18 and its working fine

please post the result when you get it ~
by the way LG V60 Demo unit DON'T have fingerprint reader, I find out this when fixing my broken phone using demo unit @@
What is LG Flash tool 18?
Do you mean LG Flash Tool V1.8.1.1023?
Or LG Up 1.18?
I have many LG V60 demo boards and whenever I attempt to flash them with LGUP command line (LGUP 1.17.0.1) I get to 85% and it stops and the phone is bricked.
