My Nexus 5x was bought last year from Hong Kong and got a bootloop issue just after the warranty :crying: So far, i know google has known this issue and there is a recall in US, Korean LG has offered a unlimited warranty to this bootloop issue. However, LG customer center from Hong Kong has rejected any maintenance of the cpu if outside its warranty :rolleyes:

Thereafter, i decided to send my 5x to China for CPU fixing, as the RAM is packed with the CPU together, the guy suggested me upgrading it to 3 or 4 GB RAM. That's how the 4GB RAM 5X comes out. :D

I've tested the OTA works fine from 6.0.1 to 7.1.1, all functions works fine too. :highfive:

How does it work? #106

Since i posted this post, i learnt something about the CPU from 5x, and how can it be upgraded, let me explain to you guys first. :highfive:

The packaging technique of 5x is using PoP, or package on package, which the processor package has pads on the top for the RAM chip and BGA on the bottom to attach to the PCB, its saves board space at the expense of assembly cost. This simply means the RAM sits on top of the SoC.

As fixing this bootloop issue, you have to remove the whole SoC+RAM block, so why not upgrade the RAM chip together? :cool:

Thanks RO.maniac has provided the information of the repair shop #241, if you are going to contact him, please do communicate in CHINESE!!!

Just talked to the dude on WeChat, he confirmed RMB400 for CPU reflow and 4GB RAM upgrade.

I also made sense of his address in somewhat of an international format:
Mr. Huang Jinhui
Yuanwang Digital Mall, 1st floor 1065
HuaQiang North Road
Shenzhen, Futian District, HuaQiang North
518000 Guangdong
People's Republic of China

WeChat ID: 784439978
Phone number: 15919836083

I will ship my other N5X first thing on Monday with the Romanian National Post Service. I will keep you updated, as soon as is gets to China. In like 2 weeks. :)

Can you provide us an email address, or any other way to contact the guy who "upgraded" your 5X? I would be interested (me and many others) in ordering the necessary part/s, and to do the transplant/implant operation at a local service...

Thanks in advance! :)

i just contact him via WeChat, however i don't believe he knows English well :eek:

btw, if your devices isn't get into Bootloop issue, i don't recommend you to upgrade it,

take your own risk if your devices cannot boot up after upgrade

pm me if you still want to do it.

    Later edit: That shipping never happened. Exams and some poor money management sucked me dry of time and cash for a while. I will probably resume this some time in fall.

    *Payment seems to be a problem since it would be done through WeChat Wallet that isn't available outside of China. Even if we make it pop up in the app by changing the language to Chinese, I'm having a hard time believing that it would support our variety of bank accounts and cards.
    So this is put to bed for some time...

    **Another method would consist of purchasing the BGA Reballing stencils from Aliexpress and then finding a local shop that specializes in BGA Reballing for various chips and let them do it. It may be more expensive than the Chinese way and you're stuck with the existing 2GB of RAM, but I find it more convenient.
