My Nexus 5x was bought last year from Hong Kong and got a bootloop issue just after the warranty 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

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.

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




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.

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?

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!
