經我深入研究呢, 發現原來之前LG G4死底板原來都係同一個問題, 就係粒CPU 焊工有瑕疵, 就連LG V10都出現同一問題, 而且我發現都有一個共通點, LG G4, V10, Nexus 5X都係用Snapdragon 808
但係呢, 我又發現其實由華為代工既Nexus 6P, 用Snapdragon 810 都有相同問題, 經我再Google, 我發現有台灣人話經TSMC(台積電)代工的Snapdragon 都有問題, 所以我懷疑呢個先係主因

關於GOOGLE 回應, GOOGLE 有位員工叫 Orrin 就係Forum 確認左部分機係有hardware問題

Hey Everyone,
We understand that a very small number of users are experiencing a bootloop issue on the Nexus 5X. We are continuing to investigate the situation, but can confirm that this is strictly a hardware related issue. For those of you that are currently experiencing this, please contact your place of purchase for warranty or repair options.
We’re sorry for the inconvenience and appreciate your continued patience.

而美國LG就話因為部機已經停左產, 唔夠零件去整, 所以決定退款.

至於香港呢, 其他巴絲打已經講左, 如果部機係經香港Play Store買既話, 就算過左保養, Google都會換新機, 但如果經其他途徑買既行貨仲有保養既話, 就需要自行聯絡LG代理解決. 過左保養既就需要自己比錢整, 仲另收檢查費$150
然後我又見有人放底板入焗爐焗一焗就開到機,

亦有人拆底板用風筒吹熱粒CPU就開得返機, 但都係暫時性

我最後選擇左風筒大法, 點知又真係成功左, 不過幾分鐘後部機一降返溫又bootloop過, 去片:

好啦, 以下就係呢個POST 既重點, 我搵到百度有大陸人搵左華強北一間叫 "遇佳科技" 既手機維修, 重新焊粒新既S808 CPU上去, 而且部機仲升級埋3GB RAM

我呢度再解一解釋點解變左3GB RAM, 原因係S808 既RAM 係痴埋同一粒Chips, 而LG G4就係S808+3GB RAM, V10係S808+4GB RAM, 估計維修個度換左粒G4用既S808落去, 之前個POST 有條痴線佬就係自己買左粒V10既S808, 然後搵人幫佢換落部5X度, 最後真係變左 4GB RAM
我諗香港LG肯退款個機會都幾微, 所以我得出既結論係, 如果係LG水貨或過左保既行貨用家, 不過考慮下呢個方法, 順便升級埋部機
