Mobo Replacement - LG V10 Q&A, Help & Troubleshooting

So I had a question... if I replaced my AT&T motherboard (H900) with a TMobile motherboard, (H901) would that technically mean I would have a unlocked boot loader and could STILL run on AT&T? Seems too good to be true.

[Q] unlock and warranty

I searched and couldn't find a clear answer to my question:
I bought an AT&T HTC One off CL and want to flash the international ROM, however, I am afraid of voiding my warranty...
1) is there any way to restore htc one back to its "locked" state after unlocking, from what I understand it is only possible to change it to "relocked"
2) Does the "relocked" status imply voided warranty? has anyone dealt with AT&T in the past?
I have seen my share of smartphones failing, including my international S3 failing into its 14th month so would really like to keep the warranty intact
Unlocking the bootloader does not necessarily void your warranty in the U.S. But it will probably make your claim a little more difficult. HTC has, in the past, honored warranty when the fault was clearly not the users fault. For example, if your power button gets stuck in the down position and can't be raised. At this time, there is no way to get the phone to show LOCKED again instead of RELOCKED. Now if HTC gets your phone and determines the issue was caused by the user, they will still replace it but charge you for the parts. You will probably have more luck working with AT&T reps in your warranty claim because they aren't trained on how to tell if your phone is unlocked/rooted as long as you aren't obvious about it.

AHEM: /Taps mic....
Simply unlocking your bootloader isn't an automatic voiding of a warranty.
I am doing a warranty return myself and the terms I agreed to were the phone must not be physically damaged, or water damaged.
Also HTC THEMSELVES will repair a phone UNDER WARRANTY with a HARDWARE DEFECT despite having an unlocked bootloader.
I have never in my several years of dealing with AT&T had a warranty refused because I rooted my phone.

Until we get S-off (which is coming soon) the bootloader cannot be made to say "LOCKED" once it has been unlocked.
Sorry for the double post, but thought of one more thing. I had to get my phone warranty swapped for dead pixels. The AT&T reps I dealt with in person tried to convince me that my device wasn't covered because, like you, I bought the phone from an individual. They said warranty are not tranferrable and only belong to the person who bought the phone. This is not true. Warranty is on the device and provided by HTC, not AT&T. They are simply acting as an intermediary to facilitate the exchange. I had a whole lot less trouble dealing with the phone support folks in getting it swapped.

Thanks for that piece of information, MOST HELPFUL!
Any idea if there will be a different unlock tool for s-off our if I can unlock and just wait for s-off?

If past exploits are any indication you're going to need root to gain s-off so go ahead and unlock.

It appears to vary based on the store and who you happen to interface with.
The safest way is to do an S-Off, remove the tampered notice, modify the splash screen, and then lock it. But that is a lot of steps, some of them a bit risky if done wrong.
Unlocked as in carrier? If you bought it from tmo, then it should still be covered unless you did something else to void the warranty.If you mean bootloader, then that voids the warranty so you're probably gonna get hit with a fee, maybe on the back end.
FWIW, I had no trouble getting my last One replaced for a stuck pixel despite bootloader unlock. I took it to a store and had the rep there initiate the exchange, though I still had to receive the replacement in the mail since I bought it online. Before sending it in I just nandroided back to stock and flashed stock recovery and that was it. I was worried for a while that they would hit me with some extra fee because of my unlocked bootloader, but it's been over a month and nothing.
I'm guessing since I had a super-obvious hardware problem (stuck pixel) nobody bothered to do a thorough check., but getting S-OFF and fixing everything to look locked is probably safer.

[Q] swaping motherboards

P769 System or partitions damaged

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.

[Q] How to carrier unlock G2 Mini

Hey guys, I bought a G2 Mini for a cheap price (under $100), but it's locked for Vodafone, and I'm on T-Mobile. It wouldn't be a problem, as I can unlock it on eBay for $3 or so, but it still has more than a year of warranty, and I don't want to lose it.
My question is: is there any method to carrier unlock this device, with a gadget like Turbo SIM (which doesn't work with recent Android versions as I read) or something, so I won't lose my warranty? Or I can only hope that they won't recognize the unlock at LG Service Center, if I have any kind of problem? I've got an Optimus L9 which had some issues, it has unlocked bootloader but they replaced its motherboard without a question, I know it's not the same, but you know.. it's still possible. I appreciate any kind of help, thanks!
