手機開不了機的原因

1、開機線不正常引起的不開機

正常情況下，按下手機開(kai)機(ji)鍵時(shi)，開(kai)機(ji)鍵的觸(chu)發(fa)端電(dian)(dian)壓應有(you)明顯變(bian)化(hua)，若無變(bian)化(hua)，一般(ban)(ban)是(shi)開(kai)機(ji)鍵接觸(chu)不良或(huo)者是(shi)開(kai)機(ji)線斷線、元件(jian)虛焊、損壞。維修(xiu)時(shi)，用外接電(dian)(dian)源(yuan)供電(dian)(dian)，觀察電(dian)(dian)流表的變(bian)化(hua)，如果電(dian)(dian)流表無反應，一般(ban)(ban)是(shi)開(kai)機(ji)線斷線或(huo)開(kai)機(ji)鍵不良。

2、電(dian)(dian)池供電(dian)(dian)電(dian)(dian)路不良引起(qi)的不開機

對于大部分(fen)手(shou)(shou)機(ji)(ji)(ji)(ji)，手(shou)(shou)機(ji)(ji)(ji)(ji)加(jia)上電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)或外(wai)(wai)接電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)后，供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓直(zhi)接加(jia)到(dao)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)工C上，如(ru)(ru)果(guo)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓未(wei)加(jia)到(dao)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)IC上，手(shou)(shou)機(ji)(ji)(ji)(ji)就(jiu)不(bu)可(ke)能(neng)(neng)開(kai)(kai)機(ji)(ji)(ji)(ji)。對于摩托(tuo)(tuo)羅拉(la)系列的手(shou)(shou)機(ji)(ji)(ji)(ji)(摩托(tuo)(tuo)羅拉(la)T2688除外(wai)(wai))，供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)有(you)所(suo)不(bu)同，電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)和外(wai)(wai)接電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)要經過電(dian)(dian)(dian)(dian)(dian)(dian)子開(kai)(kai)關(guan)(guan)轉換再(zai)加(jia)到(dao)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)IC上。也(ye)就(jiu)是(shi)(shi)說，手(shou)(shou)機(ji)(ji)(ji)(ji)的供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)有(you)兩(liang)(liang)條路(lu)徑(jing)，一(yi)(yi)路(lu)是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian);另一(yi)(yi)路(lu)是(shi)(shi)外(wai)(wai)部接口供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(帶(dai)機(ji)(ji)(ji)(ji)充電(dian)(dian)(dian)(dian)(dian)(dian)座供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)時)。當兩(liang)(liang)路(lu)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)同時供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)時，外(wai)(wai)部接口供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)優先。而這兩(liang)(liang)路(lu)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)的切(qie)換是(shi)(shi)由電(dian)(dian)(dian)(dian)(dian)(dian)子開(kai)(kai)關(guan)(guan)管來控制，主要達到(dao)對整(zheng)機(ji)(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)流起(qi)到(dao)保(bao)護作用(yong)，防止(zhi)因短路(lu)或者漏電(dian)(dian)(dian)(dian)(dian)(dian)對手(shou)(shou)機(ji)(ji)(ji)(ji)內部的集成電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)造成損壞。但是(shi)(shi)，如(ru)(ru)果(guo)電(dian)(dian)(dian)(dian)(dian)(dian)子開(kai)(kai)關(guan)(guan)損壞，中源(yuan)(yuan)(yuan)模(mo)塊就(jiu)有(you)可(ke)能(neng)(neng)得不(bu)到(dao)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓引起(qi)手(shou)(shou)機(ji)(ji)(ji)(ji)不(bu)開(kai)(kai)機(ji)(ji)(ji)(ji)。對于這種由電(dian)(dian)(dian)(dian)(dian)(dian)子開(kai)(kai)關(guan)(guan)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)的手(shou)(shou)機(ji)(ji)(ji)(ji)，由于既可(ke)以(yi)用(yong)外(wai)(wai)接電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)接口供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)，也(ye)可(ke)以(yi)通過電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)觸(chu)片用(yong)外(wai)(wai)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)加(jia)以(yi)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)。維修時可(ke)通過不(bu)同的供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)方式進行供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)，以(yi)便(bian)區分(fen)故障(zhang)范圍和確定電(dian)(dian)(dian)(dian)(dian)(dian)子開(kai)(kai)關(guan)(guan)是(shi)(shi)否正(zheng)常。一(yi)(yi)般來說，如(ru)(ru)果(guo)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)不(bu)良(liang)，按開(kai)(kai)機(ji)(ji)(ji)(ji)鍵電(dian)(dian)(dian)(dian)(dian)(dian)流表會(hui)無反應，這和開(kai)(kai)機(ji)(ji)(ji)(ji)線不(bu)良(liang)十(shi)分(fen)相似。

3、電(dian)源(yuan)IC不(bu)正常引起的(de)不(bu)開

手機要(yao)(yao)正常工作(zuo)(zuo)，電(dian)(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)(dian)路(lu)(lu)要(yao)(yao)輸(shu)出正常的(de)電(dian)(dian)(dian)(dian)壓(ya)供(gong)(gong)給(gei)負(fu)載電(dian)(dian)(dian)(dian)路(lu)(lu)。在(zai)電(dian)(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)(dian)路(lu)(lu)中，電(dian)(dian)(dian)(dian)源(yuan)(yuan)IC是其(qi)核心電(dian)(dian)(dian)(dian)路(lu)(lu)，不(bu)(bu)同品種及型號的(de)手機(ji)，供(gong)(gong)電(dian)(dian)(dian)(dian)方(fang)式亦有所不(bu)(bu)同，有的(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)(dian)路(lu)(lu)的(de)供(gong)(gong)電(dian)(dian)(dian)(dian)由幾塊(kuai)(kuai)穩壓(ya)管(guan)供(gong)(gong)給(gei)，如(ru)愛立信早期系列(lie)(T18之前)手機(ji)、部分(fen)三星系列(lie)手機(ji)等。有的(de)卻有一塊(kuai)(kuai)電(dian)(dian)(dian)(dian)源(yuan)(yuan)模(mo)塊(kuai)(kuai)直接供(gong)(gong)給(gei)，如(ru)摩托羅拉系列(lie)手機(ji)、諾基(ji)亞系列(lie)手機(ji)等。但不(bu)(bu)管(guan)怎(zen)樣，如(ru)果電(dian)(dian)(dian)(dian)源(yuan)(yuan)IC不(bu)(bu)能(neng)(neng)正常工作(zuo)(zuo)，就有可能(neng)(neng)造成(cheng)手機(ji)不(bu)(bu)開機(ji)。對于電(dian)(dian)(dian)(dian)源(yuan)(yuan)IC，重點是檢查(cha)其(qi)輸(shu)出的(de)邏(luo)輯供(gong)(gong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)、13MHz時(shi)鐘供(gong)(gong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)，在(zai)按開機(ji)鍵的(de)過程中應能(neng)(neng)測(ce)(ce)到(dao)(不(bu)(bu)一定維持住)，若(ruo)測(ce)(ce)不(bu)(bu)到(dao)，在(zai)開機(ji)鍵、電(dian)(dian)(dian)(dian)池供(gong)(gong)電(dian)(dian)(dian)(dian)正常的(de)情況(kuang)下(xia)，說明電(dian)(dian)(dian)(dian)源(yuan)(yuan)IC虛焊(han)、損(sun)壞(huai)。目前，越(yue)來越(yue)多的(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)IC采用了(le)BGA封裝，給(gei)測(ce)(ce)量(liang)(liang)和維修(xiu)帶來了(le)很大的(de)負(fu)擔(dan)，測(ce)(ce)量(liang)(liang)時(shi)可對照電(dian)(dian)(dian)(dian)路(lu)(lu)原理圖在(zai)電(dian)(dian)(dian)(dian)源(yuan)(yuan)IC的(de)外圍電(dian)(dian)(dian)(dian)路(lu)(lu)的(de)測(ce)(ce)試點上(shang)進行(xing)測(ce)(ce)試。若(ruo)判斷(duan)電(dian)(dian)(dian)(dian)源(yuan)(yuan)IC虛焊(han)或損(sun)壞(huai)，需重新植(zhi)錫、代換(huan)，這需要(yao)(yao)較高的(de)操作(zuo)(zuo)技巧，需在(zai)實踐中加(jia)以磨練。

4、系統對鐘和(he)復位不正常(chang)引(yin)起的(de)不開(kai)機

系統時鐘是CPU正常工作的條件之一，手機的(de)(de)系(xi)統時(shi)(shi)(shi)(shi)鐘(zhong)(zhong)(zhong)一(yi)(yi)般(ban)采用(yong)(yong)(yong)13MHz，13MHz時(shi)(shi)(shi)(shi)鐘(zhong)(zhong)(zhong)不(bu)(bu)正(zheng)(zheng)常，邏輯(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)不(bu)(bu)工作(zuo)，手(shou)機(ji)(ji)(ji)(ji)不(bu)(bu)可(ke)能開機(ji)(ji)(ji)(ji)。13MHz時(shi)(shi)(shi)(shi)鐘(zhong)(zhong)(zhong)信號(hao)應(ying)能達到一(yi)(yi)定的(de)(de)幅度并穩定。用(yong)(yong)(yong)示波(bo)器(qi)(qi)測(ce)13MHz時(shi)(shi)(shi)(shi)鐘(zhong)(zhong)(zhong)輸出端上的(de)(de)波(bo)形(xing)(xing)(xing)，如(ru)(ru)果無波(bo)形(xing)(xing)(xing)則檢(jian)測(ce)13MHz時(shi)(shi)(shi)(shi)鐘(zhong)(zhong)(zhong)振(zhen)蕩電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(對于13MHzVCO，供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓加到13MHzVCO的(de)(de)一(yi)(yi)個腳亡，對于13MHz晶(jing)振(zhen)組(zu)成(cheng)的(de)(de)振(zhen)蕩電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)，這個供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓一(yi)(yi)般(ban)供(gong)給(gei)中(zhong)頻(pin)IC)，若有(you)正(zheng)(zheng)常電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓則為13MHz時(shi)(shi)(shi)(shi)鐘(zhong)(zhong)(zhong)晶(jing)體、中(zhong)頻(pin)IC或(huo)(huo)13MHzVCO壞(huai)。注意，有(you)的(de)(de)示波(bo)器(qi)(qi)在晶(jing)體上測(ce)可(ke)能會使(shi)晶(jing)體停振(zhen)，此時(shi)(shi)(shi)(shi)，可(ke)在探頭(tou)上串接一(yi)(yi)個幾十皮法(fa)以(yi)(yi)下的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)。有(you)條件的(de)(de)話，最(zui)好使(shi)用(yong)(yong)(yong)代(dai)換(huan)法(fa)進行維修，以(yi)(yi)節約(yue)時(shi)(shi)(shi)(shi)間(jian)，提高(gao)效率。13MHz時(shi)(shi)(shi)(shi)鐘(zhong)(zhong)(zhong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)起振(zhen)后，應(ying)確(que)保13MHz時(shi)(shi)(shi)(shi)鐘(zhong)(zhong)(zhong)信號(hao)能通過電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)及(ji)放大電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)輸人到CPU引(yin)腳上，測(ce)試CPU時(shi)(shi)(shi)(shi)鐘(zhong)(zhong)(zhong)輸入腳，如(ru)(ru)沒有(you)，應(ying)檢(jian)查線(xian)路(lu)中(zhong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)、放大電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)是(shi)(shi)否虛焊或(huo)(huo)無供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)及(ji)損壞(huai)。另外(wai)，有(you)些手(shou)機(ji)(ji)(ji)(ji)的(de)(de)時(shi)(shi)(shi)(shi)鐘(zhong)(zhong)(zhong)晶(jing)體或(huo)(huo)時(shi)(shi)(shi)(shi)鐘(zhong)(zhong)(zhong)VCO是(shi)(shi)26MHz(如(ru)(ru)摩(mo)托羅拉V998、諾(nuo)基3310手(shou)機(ji)(ji)(ji)(ji))或(huo)(huo)19.5MHz(如(ru)(ru)三星A188手(shou)機(ji)(ji)(ji)(ji))，產生的(de)(de)振(zhen)蕩頻(pin)率要經過中(zhong)頻(pin)IC分頻(pin)為13MHz后才供(gong)給(gei)CPU。復(fu)位(wei)(wei)(wei)信號(hao)也是(shi)(shi)CPU工作(zuo)工作(zuo)條件之一(yi)(yi)，符(fu)號(hao)是(shi)(shi)RESET，簡(jian)寫RST，諾(nuo)基亞乎機(ji)(ji)(ji)(ji)中(zhong)用(yong)(yong)(yong)PURX表示。復(fu)位(wei)(wei)(wei)一(yi)(yi)般(ban)直接由電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)IC通往(wang)CPU，或(huo)(huo)使(shi)用(yong)(yong)(yong)一(yi)(yi)專(zhuan)用(yong)(yong)(yong)復(fu)位(wei)(wei)(wei)小集成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)。復(fu)位(wei)(wei)(wei)在開機(ji)(ji)(ji)(ji)瞬(shun)間(jian)存在，開機(ji)(ji)(ji)(ji)后測(ce)量(liang)(liang)時(shi)(shi)(shi)(shi)己為高(gao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)平(ping)。如(ru)(ru)果需(xu)要測(ce)量(liang)(liang)正(zheng)(zheng)確(que)的(de)(de)復(fu)位(wei)(wei)(wei)時(shi)(shi)(shi)(shi)間(jian)波(bo)形(xing)(xing)(xing)，應(ying)使(shi)用(yong)(yong)(yong)雙蹤示波(bo)器(qi)(qi)，一(yi)(yi)路(lu)測(ce)CPU電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)，一(yi)(yi)路(lu)測(ce)復(fu)位(wei)(wei)(wei)。維修中(zhong)發現，因(yin)復(fu)位(wei)(wei)(wei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)不(bu)(bu)正(zheng)(zheng)常引(yin)起的(de)(de)手(shou)機(ji)(ji)(ji)(ji)不(bu)(bu)開機(ji)(ji)(ji)(ji)并不(bu)(bu)多見。

5、邏輯電路不正常(chang)引起(qi)的不開機

邏輯電路重點檢測CPU對各存儲器的片選信號CE和許可信號OE，這些信號很重要，但關鍵是必須會尋找這些信號，由于越來越多的手機邏輯電路采用了BGA封裝的集成電路，給查找這些信號帶來了很大的困難。有條件的話最好對照圖紙來查找這些信號及其測量點。片選信號是一些上下跳變的脈沖信號，如果各存儲器CE都沒有，說明CPU沒有工作，補焊、重焊、代換CPU或再仔細檢查CPU作的條件是否具備。如果某個存儲器的片選信號沒有，多為該存儲器損壞。如果CE信號都有，說明CPU-F.作正常，故障可能是軟件故障或總線故障以及某個存儲器損壞。手機在使用(yong)中經常會(hui)引起(qi)(qi)機板(ban)變(bian)形，如按按鍵、摔、碰等外(wai)力原因會(hui)引起(qi)(qi)某(mou)些(xie)芯(xin)片脫焊，一般補焊或(huo)重焊這些(xie)芯(xin)片會(hui)解決大部分問(wen)題。當重焊或(huo)代換正常的芯(xin)片還不能開(kai)機，并(bing)且使用(yong)免拆機維修(xiu)儀讀寫也不能通過時，應逐個測量(liang)外(wai)圍電路和代換這些(xie)芯(xin)片。

6、軟件不正(zheng)常引起的(de)不開機

手機在(zai)開機過程中，若軟(ruan)(ruan)件(jian)通不過就會(hui)(hui)不開機，軟(ruan)(ruan)件(jian)出錯(cuo)主要是(shi)存儲器資料(liao)不正(zheng)常，當線(xian)路沒有(you)明顯(xian)斷線(xian)時(shi)(shi)，可以(yi)先代換正(zheng)常的(de)(de)碼(ma)片(pian)、版本或重寫(xie)(xie)軟(ruan)(ruan)件(jian)，有(you)的(de)(de)芯片(pian)內電路會(hui)(hui)損壞，重寫(xie)(xie)時(shi)(shi)則(ze)不能通過。重寫(xie)(xie)軟(ruan)(ruan)件(jian)時(shi)(shi)應將原來(lai)資料(liao)保存，以(yi)備應急修復。

7、其它原因引起的不開(kai)機(ji)

手(shou)(shou)機(ji)不開機(ji)故(gu)障的(de)原因(yin)還有很多，如液晶顯(xian)示屏不良(liang)、元件(jian)(特(te)別是功放)短(duan)路(lu)等都有可(ke)能(neng)引(yin)起手(shou)(shou)機(ji)不開機(ji)，還有一(yi)些(xie)機(ji)型必須用(yong)到32.768kHz的(de)實時(shi)(shi)時(shi)(shi)鐘(zhong)作為碼片時(shi)(shi)鐘(zhong)信號和睡眠時(shi)(shi)鐘(zhong)信號。若32.768kHz實時(shi)(shi)時(shi)(shi)鐘(zhong)不正(zheng)常，也可(ke)能(neng)造(zao)成手(shou)(shou)機(ji)不開機(ji)。引(yin)起32.768kHz時(shi)(shi)鐘(zhong)不正(zheng)常的(de)因(yin)素主要有時(shi)(shi)鐘(zhong)備用(yong)電(dian)池短(duan)路(lu)、32.768kHz時(shi)(shi)鐘(zhong)壞(huai)等。所以，在維修(xiu)手(shou)(shou)機(ji)不開機(ji)時(shi)(shi)要結合(he)具(ju)體電(dian)路(lu)具(ju)體分析，只要對手(shou)(shou)機(ji)的(de)原理理解正(zheng)確，思路(lu)清楚，不開機(ji)故(gu)障一(yi)般都可(ke)以排(pai)除。

手機開不了機如何解決

第一步：檢(jian)查電(dian)池是(shi)(shi)否(fou)有(you)電(dian)，電(dian)池沒電(dian)了，手機(ji)自然沒有(you)動力去開機(ji)，如果怎么沖它都不會啟動的話可以檢(jian)查一下充(chong)電(dian)器(qi)是(shi)(shi)否(fou)工(gong)作，接口(kou)是(shi)(shi)否(fou)損(sun)壞(huai)，用萬能(neng)充(chong)充(chong)電(dian)或檢(jian)測電(dian)量。

第二步：檢(jian)查電池(chi)是(shi)否損(sun)壞或者壽命已(yi)到，電池(chi)是(shi)消耗品，如(ru)果損(sun)壞或者使用不當導致電池(chi)過早損(sun)壞，可以嘗試換(huan)一塊電池(chi)，看一看是(shi)否可以啟動，如(ru)果問題解(jie)決，就(jiu)需要(yao)更換(huan)電池(chi)。

第(di)三步：進水(shui)或刷機造成(cheng)人(ren)為性損(sun)壞，這種問題就(jiu)是(shi)自身的原(yuan)因(yin)了(le)，進水(shui)的話(hua)用吹(chui)風機吹(chui)一(yi)吹(chui)，拆機烘(hong)烤試一(yi)試，如果(guo)摔壞了(le)，內部零件損(sun)毀，就(jiu)需要找維(wei)修中(zhong)心(xin)維(wei)修了(le)。如果(guo)刷機造成(cheng)無法(fa)開機，可以重新刷機嘗試恢復。

第四步：如果(guo)基本(ben)的(de)(de)方法(fa)都嘗試(shi)過了(le)，還是無效的(de)(de)話，就只能去找專業的(de)(de)維修中(zhong)心(xin)來(lai)進行維修，一般無法(fa)開機的(de)(de)故障自己(ji)不好解(jie)決，也可以試(shi)試(shi)搜(sou)索，看看有沒(mei)有適合你的(de)(de)解(jie)決辦(ban)法(fa)。

手機開不了機怎么刷機

這里介紹最簡單的刷(shua)機(ji)方式：一種是使用軟件下載ROM一鍵在線刷(shua)機(ji)！另外一種是把ROM復制(zhi)到SD卡里面然后進(jin)入recovery模式進(jin)行(xing)刷(shua)機(ji)！

1、用軟(ruan)件(jian)一鍵在線刷(shua)機：

步驟一(yi)、這(zhe)個(ge)需要安裝(zhuang)一(yi)款刷機(ji)軟(ruan)件(jian)(jian)，這(zhe)個(ge)軟(ruan)件(jian)(jian)用的(de)(de)人也非常的(de)(de)多，還有(you)一(yi)件(jian)(jian)ROOT的(de)(de)功能，刷機(ji)也需要ROOT。我們百度搜索“卓大師”，然后點(dian)擊下載安裝(zhuang)。

步(bu)驟二、然后我們在進(jin)入(ru)自己的(de)手機(ji)，點擊設置，然后點擊開(kai)發人員選(xuan)項。把USB調(diao)試打(da)開(kai)。不同安卓版本的(de)手機(ji)打(da)開(kai)的(de)位置也不一樣。自己在設置里面找找就能看到(dao)。

步驟三、然后把手機(ji)(ji)(ji)用(yong)數(shu)據線連(lian)接好(hao)電腦，然后在打開安(an)裝好(hao)的卓大(da)師(shi)，卓大(da)師(shi)連(lian)接手機(ji)(ji)(ji)成功之后點擊ROM專區(qu)。這里面會(hui)有很多手機(ji)(ji)(ji)的刷機(ji)(ji)(ji)包(bao)。找一個適合(he)自(zi)己機(ji)(ji)(ji)型(xing)的刷機(ji)(ji)(ji)包(bao)下載(zai)。

步驟四、然后在(zai)按照(zhao)上圖的(de)指(zhi)示，點(dian)擊(ji)下面的(de)下載狀態，打開之后就會看到ROM下載的(de)位置。

步驟(zou)五(wu)、然(ran)后把(ba)你(ni)下載(zai)的(de)ROM的(de)壓縮文件復制(zhi)出來(lai)。這個(ge)文件也可以直接復制(zhi)到(dao)SD卡(ka)里面進入recovery模式進行刷機，下載(zai)刷機包(bao)是最(zui)重要的(de)。而且刷機包(bao)呀下載(zai)適合自己(ji)機型的(de)，不然(ran)很(hen)容易(yi)變(bian)磚。

步驟六、下(xia)載完之后會出現刷(shua)機(ji)的(de)按鈕(niu)，或者(zhe)我(wo)們進入導航里面的(de)一鍵刷(shua)機(ji)，選擇好刷(shua)機(ji)包(bao)點(dian)擊(ji)下(xia)一步，選擇是否備案，然后點(dian)擊(ji)下(xia)一步就坐等刷(shua)機(ji)成功提(ti)示啦。

2、Recovery模式刷機方法(fa)：

步驟一、首先要確定你的手機是否(fou)刷(shua)(shua)(shua)入(ru)了Recovery，如(ru)果沒有的(de)需要(yao)刷(shua)(shua)(shua)入(ru)Recovery才能進(jin)入(ru)Recovery進(jin)行刷(shua)(shua)(shua)機。這里后續在為大家(jia)演示刷(shua)(shua)(shua)入(ru)Recovery的(de)方(fang)法。

步驟二、然后我們在(zai)進入設置(zhi)把USB調試關閉掉，把刷機(ji)包復制(zhi)到你的SD卡里面(mian)。關閉了USB調試才能(neng)讀取(qu)出(chu)來你的手機(ji)內存。

步驟三、然后在進(jin)入(ru)(ru)recovery模(mo)式(shi)(shi)，進(jin)入(ru)(ru)recovery模(mo)式(shi)(shi)的(de)按鍵有(you)(you)的(de)不一樣。有(you)(you)的(de)可以從電(dian)腦控制進(jin)入(ru)(ru)recovery模(mo)式(shi)(shi)，有(you)(you)的(de)按著開(kai)機鍵+音量鍵就能進(jin)入(ru)(ru)recovery模(mo)式(shi)(shi)。進(jin)入(ru)(ru)recovery模(mo)式(shi)(shi)之后先清除所有(you)(you)的(de)數(shu)據。

步驟四、然后(hou)我們在清除手(shou)機里面(mian)的(de)緩(huan)存(cun)數據，這些操作(zuo)上下就可(ke)以使用音量鍵(jian)調節。確定就是開機鍵(jian)。

步驟五、然后我們(men)在選擇刷(shua)(shua)機包(bao)，我們(men)是裝在SD卡上面的。所(suo)以從SD卡上面選擇刷(shua)(shua)機包(bao)。

步驟六、我們(men)的(de)刷機包是ZIP文(wen)件，點擊(ji)從SD卡上面(mian)選擇(ze)(ze)ZIP文(wen)件。然后選擇(ze)(ze)刷機包的(de)文(wen)件點擊(ji)確(que)定即可。

步驟七、刷機成(cheng)(cheng)功(gong)之后會有成(cheng)(cheng)功(gong)的提(ti)示(shi)，然后返回重啟(qi)系統(tong)即(ji)可(ke)進入你刷的新系統(tong)里面了(le)。
