Nexus 5X H790 with 4GB RAM upgrade.. H791? - Nexus 5X Q&A, Help & Troubleshooting

Hello all. I purchased a Nexus 5X systemboard from AliExpress. I was trying to breath new life into my 5X. However, i'm pretty sure they sent me an H791 board. The listing is for an H790. Since there are no markings on the systemboard, Is there anywhere in the software that lists the model?. Could anyone point me in the right direction? I'm on Project Fi and definitely want to use the CDMA bands.

Any help would be greatly appreciated. Thank you
James

I ordered this board twice https://de.aliexpress.com/item/Oudini-ENTSPERRT-H791-Mainboard-arbeit-f-r-LG-Nexus-5X-Mainboard-Original-f-r-LG-H791/32846103543.html?spm=a2g0s.9042311.0.0.4aa94c4dMVj9mH
and that is definitely a H791 Board.
In the bootloader you can still see what kind of board it is.

[Q] LG G3 - Korean model for UK?

Hello everyone!
I've done some reading on the forums (so I hope I haven't missed a similar topic)
and I have a few questions to ask. Being the proud UK owner of a G2, the best phone I've ever used hands down, I am definitely ready to move onto the G3 !
I am seriously thinking of buying the Korean version - 32 Gig, 3 G of RAM sound more futureproof than 16 Gig, 2 for the same price nevertheless. However, I have a few questions for anyone who either has knowledge or has owned a Korean product before.
1) LTE bands and frequence. According to this: http://en.wikipedia.org/wiki/Vodafone_UK#Radio_frequency_summary Vodafone, my provider, uses both band 20 and 7 for LTE. Now there are three LG variants, the L, S and K. According to this: http://optimusforums.com/threads/ko...ide-lte-band-differences-pros-and-cons.13134/ , it's just the L that has one of the two LTE bands used by Vodafone (And seemingly by most UK providers). Am I reading this wrong, or is it that the other two models would not support LTE?
2) Warranty - I guess this goes out to those who have actually owned one In the (un)likely event something goes wrong, what's the process of dealing with it - shipping it back and forth to Korea? I assume LG doesn't support Korean products locally.
3) Modding/Roming. Once more based on : http://optimusforums.com/threads/ko...ide-lte-band-differences-pros-and-cons.13134/, most mods that come out come out for the international models. Is this a reality? I've never been following models/variants much, but is it quite possible that buying from a Korean market may result in me never getting access to the good mods out there?
Thanks for reading, for answering (and for possibly trolling me ), and hope my questions make some sense.
After much Dilemma myself, I was in the same position as you are now in, I couldn't find any info on which model to go for, the F400K or the F400S variant, I spoken to my carrier and they gave me the gsm frequencies (I am in ireland) and then spoken/live chat with the supplier of the LG G3 from Ebay and they also directed me in the right way. I received my Brand New LG G3 F400K yesterday from Korea, and it work brilliantly. From my knowledge here in Ireland we run on the same basebands as you in the UK.
Perhaps the supplier of the phone can also direct you in the right direction, I initially ordered the F400S, but after discussing it with the supplier it became apparent that the F400K was the one for me.
Hope that helps you. I have brilliant 3G coverage here (4G not over here in my location yet) so I cant guide you on this.
Thanks
There is a good youtube video guide here: https://www.youtube.com/watch?v=mj_KUqkH4oQ on Korea models too if your importing. Shows whats in the box and talks about the pros and cons.

I wouild definitely upgrade from the S3 to the LG G3, I have had the Samsung S2, S3, S4, HTC One (M7), LG G2 and now the LG G3 and by far its the best phone I have ever owned, admittidely I have only had it a few days, but you can completely see the difference between them, I used to love Samsung, but ever since I had the LG G2 I am now a True LG Fan, Samsung have gone in the way of putting too many gimmicks into their phones, and also releasing different cariants of their flagship, ie, S5, and now S5 prime...etc. Definitely worth the purchase for the LG G3. Well worth the money. Battery life is great, Camera is Awesome, its quick and responsive with the 3GB Ram. The Brightness/Contrast is by far the best I have seen on any phone, The Display is awesome, QHD at its best. I love my G3

H815 and H815t - Custom Roms compatibility

Hello everyone,
I've tried looking for an answer whether roms, kernels and etc. are compatible between the two models.
I'm currently in the U.S and I have an opportunity to buy either one of them.
In fact, I found a store selling the H815t (with leather back) around 200$ cheaper than the H815.
If it was a much smaller difference, I wouldn't consider it but the price is tempting.
On the other hand, if someone knows about a physical store in Manhattan that sells the H815 (even with the plastic back) for 500$ or less, I would really appreciate it!!
edit: forgot to mention that I'm looking for an unlocked version (not branded in any way)
Thanks in advance!
Nobody knows about this?
The European version of the 815 is the only one with an unlockable bootloader. So, any rom that might be available at the moment is only for the European version.
Thank you creaky for your reply, it's much appreciated.

Need help to buy G3.

Hi everybody. I'm going to buy a G3 for my sister. I am in USA atm but my sister is gonna use it in Turkey. So she needs an unlocked version of the phone. I was searching on aliexpress and found that seller. Both seller's and product's ratings are high. My question is that there are some versions of the phone, I wasn't sure if she can use the phone in Turkey if I buy the US version "D850" which is $250. Otherwise I'll buy the D855 EU version which is $313. So what do you think about it? I can't copy the link because I'm a new member. But I can email it though. Thanks everyone.
Don't buy g3. I switched my g2 with g3 and I wish I didn't. G3 is so lame. Don't buy it. Also I'm from Turkey and if you send phone from US to Turkey it must be passport registered and also must have sim unlocked. So listen my words and don't buy g3 and don't send another phone from US to Turkey. There is so much work to do and not worth it.

You failed to give one proper argument why not to but the G3.
OP, if it were me, I'd go for a D802 (G2 international). The G3 has QHD (not that good, too), removable battery (relatively irrelevant, but good because the battery life is rather horrid) and a micro SD slot (if you really really need it). All of which, IMO, not worth it.

Yeah sorry about that I was on the road. G3 sucks because of overheating, quick battery drain and it's really slow for that 2,5 processor. I switched from g2 to g3 for Android M update but M update will not solve those issues I guess.

You have to know what bands are using on turkey.
I'm from Argentina, we use band 4 and 17 to lte/4g networks so d850 from AT&T works perfect here.
Before this g3 i haved d855ar (an international version maded in Argentina with open bands) and I can tell you the d850 works much better than d855ar.
Another point is ram. I readed so much people saying "3gb and 2gb works equally well", now, with the 3gb ram version on my hands and 2gb version on my table I can say that's not true! The difference is appreciated. So, if you can and the bands match with turkey operators buy 3gb ram version.

Buying HTC One M8 from Aliexpress, question about model.

Hey guys,
Has anyone here bought or had anything to do with Aliexpress? I want to buy an HTC One M8 my self, but I come across different models, which are usually 16/32GB EU and 16/32GB US version. for example: http://www.aliexpress.com/item/Unlo...G-WIFI-Quad-Core-5-0-Dual-4MP/1993568822.html
Does anyone know what is the difference between them? Could I still use the US version in Europe? US version is cheaper and has more space (16GBvs32GB).
And if anybody bought from there, what is your experience, was everything okay?
Thanks in advance
useful
Yeah, I want to know too, as prices are significantly lower than ebay, like 20% off
did anyone bought from there?

Read through the feedback, though stars are high. Couple of them are trying to change the faulty devices they received (which is gonna take lot of time). Also, there could be problem with the antenna not working for US LTE bands. By the way, US CDMA (Verizon/Sprint) won't work on this. Also, if it comes with SIM locked version, you will have to do all the research and work (saw recently in M8 forum). Maybe contact the seller and know product ID, network bands etc

LG G4 motherboard swap

Hi guys,
Wanted to ask if it is possible to swap the model of the motherboard on LG G4.
I have a broken H815 (bootloop) but the housing and display are OK.
I want to get a mother board from Korean Model F500L S K. Are they the same dimensions and does korean mainboard fit on my housing and connect to camera display etc?
And are the korean models affected by the boot loop since I'm no seeing any of them on the internet.
Yes, the motherboards have the same dimensions. It will work
Korean version probably not as popular
Get h815 again
Korean version has similar mobo as the H815, but as mentioned above, its not that that's why you dont see them bootlooped. Only advantage of the F500 is the new 7.0 FW.
Bootloop is a known problem of the LG G4.
The cause is a loose contact on the PCB.
LG offers a free repair.
Owners of a LG G4 affected by the bootloop are requested by the company to contact their mobile operator to initiate the repair process.
Customers who have purchased the G4 in free trade are kindly requested to contact LG support directly.
The repair takes place within the framework of the guarantee conditions and is therefore not associated with costs for the owner.
In addition, the company apologizes for the inconvenience that the previous solutions have brought to customers.
Previous misdiagnosis resulted in the replacement of wrong parts of the smartphone.

Nah, I'm not interested on the os version.
I just was wondering if F500's have less bootloop issues.

Well Thank YOU very much for the answer, I'm very aware why the bootloop problem was occurring and know the whole history of the problem.
But I live in Kosovo and we don't have an official lg retail store.
I contacted LG Serbia and explained them my situation. But they were willing to help just the cases when phones where bought in Serbia, so nothing for me :crying:
Since you provided some information about "free trade" phones. Is there still a chance for me to get a fix for my phone. Since when it bootlooped it was only 8 months old. So well under the "1 year warranty policy".
Thank You Very much again.
The F500 which is the Korean version I think has LTE bands/frequencies missing or disabled which makes it a no go for use in western europe at least. It might be okay on some networks depending on what frequencies your network provider uses but in general I'm sure the F500 is the most limited version when it comes to working frequencies so it would be much better to get H815 or H811. The F500 mobo is exactly the same shape as other models btw.

Your welcome. My first G4 was a F500 and I found that 2g didn't work in bad signal areas so I couldn't even make a phone call. Also 4G+ didn't work either. It was possible to put H815 firmware on it but that did NOT enable the missing frequencies so I had to buy a new one.

Yeah a phone with no 2G and 4G is probably useless.
But now I wonder if H811 European models, suffer less from bootloop, because if I decide to buy a new mother board the last thing I want to happen is my phone dying again.
I talked to a mobile phone shop owner here and he told me that they just returned many G4 since they still bootlooping (after only 1 month of use). And they won't sell them anymore.

I bought a refurbished G4 for 170 euro. It has a s/n of 701, in other works very recently manufactured....I have it working fine for 5 months now with no issues at all. So I would only buy one with serial 609 upwards. It's not know for certain which one is okay but the more recent the better. It does not matter at all whether is F500/H815/H811/etc where bootloop issue is concerned.

Thank you so much for the advice.
Yesterday I found a G4 H811 in a mobile shop here. But it was S/N 401 so a big NO NO for that
I will be thinking of buying a brand new mother board from china and replace it myself and it is half the price of a new phone.

I asked the China supplier what was the serial number and he woulnt tell me. Thls means that althought the board is new and unused it may still be an old one with bootloop issue down the line.
The best thing to do is make sure s/n is 701 up. You can ask eBay seller what is s/n by email before buying if buying used one. They will be happy to tell you. That what I did and enjoying fone since!
