bootlooped motherboard replacement with a bad imei one? - LG V10 Q&A, Help & Troubleshooting

So my t mobile (unlocked ) V10 bootlooped and i've come across a working t mobile motherboard with a bad imei.I'm in Canada, so it should still work correct?
I'm only trying to repair this thing because its a great phone aside from the faulty heat dissipation design.If you look inside the v10 , the thermal pad LG uses is ridiculous.i'm pretty sure it doesn't even contact with the processor when assembled.I'm also going to add a better themal pad and apply thermal paste to better cool and prevent the bootloop.
My only question is, if the bad imei board will work in Canada?
I still have my old board can i swap imei with it?
Swapping imei is legal in Canada and i would be doing it using the imei of my old broken motherboard so please no BS about that or how i'd be using the board of a potentially stolen/financed/lost phone.
Any input would help!
thanks

[Q]Replacement Mainboard

Hey guys,
Friend of mine managed to damage his SGS2's mainboard while replacing the headphone jack, any idea where he may find a spare?
I searched, but nothing came up in this forum..
Thanks!

Quick bump for the evening
If you are replacing the motherboard, you are replacing the phone completely. as the chip on the damaged motherboard contains the imei and other information about your phone.
Anew mother board will have a different imei and have to be registered with your provider as it is basically a new phone.
That's 100% fine, my provider doesn't lock IMEI's out of it's network.
I just need to find where to get a new board and the /efs folder to match.
Any ideas?
Look on eaby for broken phones, some with broken screen are really cheap.

Q - Advice

Hi,
I smashed my screen on my I9305 and not realizing it i put the I9300 replacement screen on the phone. I have had issues with the IMEI null and not picking up signal. I have tried all mentioned methods on here to restore but none have worked. I gave up an contacted a repair center and they have said that putting a I9305 screen on will solve the problem. Is this correct as I don't want t spend money if it is not correct.
Thanks

As far as my knowledge goes screen replacing doesn't effect anything until or unless you have badly messed up some hardware in the process. The module used to allow communication on i9300 and i9305 is same plus it doesn't has to do anything with screen. You can try to put a new SIM card module to see whether the phone picks up signal or not. The best bet for you is that you don't go around spending money for a thing that is perfectly fine.
One more bet is that you may have ruined some inner hardware during the smash and not in the replacing process.
Hit Thanks if I helped.
did you replace the screen with a heat gun like in some videos on youtube? if so you might have damaged some of the sensible parts of the sIII if you didn't take them off before, for example the antenna or the simcard module like the one above me said.
so i think it will be difficult to find the broken part - changing all possible parts by yourself is very expensive and time-consuming.
I recommend you to consult an official samsung repair center (which will be expensive, too) or sell your phone as broken and invest the money in a new one...

No I replaced the screen with a genuine service pack one which came pretty much whole. Didn't heat anything just swapped them over and turned it on. Advice I got was that it was because I put on the i9300 screen on is why I couldn't restore my imei number.
Now selling the motherboard if anyone is interested

[Q] Motherboard replacement - will IMEI be lost?

Hi
I have an S2 which is hard bricked, it is not stolen or barred.
I have bought a replacement motherboard and a shop will fit it for me as I lack the technical skill.
My question is will my IMEI be lost?
If so how do I recover it, assuming the phone is then working?
Many thanks in advance

Generally speaking, if it's a new MB by a Samsung service centre you'll get the same IMEI (but not in all countries). If you/someone else puts a 2nd hand board in, yes, the IMEI will change. Either way it makes no difference to you as a user, your phone will still have a unique IMEI & work as it should with either scenario.
You messing around with the IMEI in order to try to 'recover' your old one should it change will lead to a busted phone (again). Don't attempt this because it just isn't necessary.

C6806 transfer memory chip to new logic board

Does anyone have any experience soldering a new memory chip to a logic board? Basically, I flashed a FTF on my C6806 (GPE) Z Ultra which was a big no-no. I just bought a working logic board with a bad IMEI. I never used it as a phone, so WiFi is perfectly fine. However, if there is a way to transfer the "new" bad IMEI's memory chip to the "old" messed up board, I would certainly be willing to try.. The other question is, will this have any effect, as the IMEI might be on that chip so all I'd be doing is transferring a bad IMEI to another board, which will still have a bad IMEI.
Or can I repogram my non-working logic board's IMEI to the "new" logic board I got and replace the bad IMEI?
Sorry for the confusing post. Just looking for options before I install the bad IMEI board and only have a wifi tablet.
Thanks in advance.

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.

Thanks, you are right, Marshmallow rom - Android 6. The shop said the board is "new"... not sure if it's refurbished or not, let me give it a try and see where it'll get me, thanks shinning man!

install CPU Temp app or something that can monitorize your cpu temperature and be careful, if they dont go higher than 42/45 then you are good.

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.
