手機開不了機的原因

1、開(kai)機線不(bu)正常引起的不(bu)開(kai)機

正常情況下，按下手機開(kai)機(ji)(ji)鍵(jian)(jian)(jian)時，開(kai)機(ji)(ji)鍵(jian)(jian)(jian)的(de)觸(chu)發端電(dian)(dian)壓應有明顯(xian)變(bian)化(hua)(hua)，若無變(bian)化(hua)(hua)，一般(ban)是開(kai)機(ji)(ji)鍵(jian)(jian)(jian)接觸(chu)不(bu)良或者是開(kai)機(ji)(ji)線斷(duan)線、元件(jian)虛焊、損(sun)壞。維修時，用外(wai)接電(dian)(dian)源供電(dian)(dian)，觀察電(dian)(dian)流(liu)(liu)表的(de)變(bian)化(hua)(hua)，如(ru)果電(dian)(dian)流(liu)(liu)表無反(fan)應，一般(ban)是開(kai)機(ji)(ji)線斷(duan)線或開(kai)機(ji)(ji)鍵(jian)(jian)(jian)不(bu)良。

2、電池供電電路(lu)不良引起的不開機

對(dui)(dui)(dui)于大(da)部分手機(ji)(ji)(ji)，手機(ji)(ji)(ji)加(jia)上電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池或外(wai)接電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)后，供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓直接加(jia)到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)工(gong)C上，如(ru)果(guo)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓未(wei)加(jia)到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)IC上，手機(ji)(ji)(ji)就不(bu)可(ke)能開(kai)(kai)(kai)機(ji)(ji)(ji)。對(dui)(dui)(dui)于摩托羅(luo)拉系列的(de)手機(ji)(ji)(ji)(摩托羅(luo)拉T2688除(chu)外(wai))，供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)有(you)(you)所不(bu)同，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)和外(wai)接電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)要(yao)經過電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子開(kai)(kai)(kai)關(guan)轉換(huan)再加(jia)到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)IC上。也(ye)就是(shi)(shi)(shi)說(shuo)，手機(ji)(ji)(ji)的(de)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)有(you)(you)兩(liang)條(tiao)路(lu)徑，一(yi)路(lu)是(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian);另一(yi)路(lu)是(shi)(shi)(shi)外(wai)部接口(kou)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(帶機(ji)(ji)(ji)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)座供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)(shi))。當兩(liang)路(lu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)同時(shi)(shi)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)(shi)，外(wai)部接口(kou)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)優先。而這(zhe)兩(liang)路(lu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)的(de)切換(huan)是(shi)(shi)(shi)由電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子開(kai)(kai)(kai)關(guan)管來控制，主要(yao)達(da)到對(dui)(dui)(dui)整(zheng)機(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流起(qi)到保護作(zuo)用(yong)，防止因短(duan)路(lu)或者漏電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)對(dui)(dui)(dui)手機(ji)(ji)(ji)內部的(de)集成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)造(zao)成損壞。但(dan)是(shi)(shi)(shi)，如(ru)果(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子開(kai)(kai)(kai)關(guan)損壞，中源(yuan)(yuan)(yuan)模塊就有(you)(you)可(ke)能得(de)不(bu)到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池的(de)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓引起(qi)手機(ji)(ji)(ji)不(bu)開(kai)(kai)(kai)機(ji)(ji)(ji)。對(dui)(dui)(dui)于這(zhe)種(zhong)由電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子開(kai)(kai)(kai)關(guan)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)手機(ji)(ji)(ji)，由于既可(ke)以(yi)(yi)用(yong)外(wai)接電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)接口(kou)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，也(ye)可(ke)以(yi)(yi)通過電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池觸片用(yong)外(wai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)加(jia)以(yi)(yi)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。維(wei)修時(shi)(shi)可(ke)通過不(bu)同的(de)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)方式進行供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，以(yi)(yi)便區分故障范圍和確定電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子開(kai)(kai)(kai)關(guan)是(shi)(shi)(shi)否(fou)正常。一(yi)般來說(shuo)，如(ru)果(guo)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)不(bu)良，按開(kai)(kai)(kai)機(ji)(ji)(ji)鍵電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流表會無(wu)反應，這(zhe)和開(kai)(kai)(kai)機(ji)(ji)(ji)線(xian)不(bu)良十分相似。

3、電源IC不正常引起的不開

手機要(yao)正(zheng)常(chang)工作(zuo)(zuo)，電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)路(lu)要(yao)輸出(chu)正(zheng)常(chang)的(de)(de)電(dian)(dian)(dian)(dian)壓供(gong)給(gei)(gei)(gei)負載(zai)電(dian)(dian)(dian)(dian)路(lu)。在(zai)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)路(lu)中(zhong)(zhong)，電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)IC是(shi)其核心電(dian)(dian)(dian)(dian)路(lu)，不(bu)(bu)(bu)同品種(zhong)及型號的(de)(de)手(shou)機(ji)，供(gong)電(dian)(dian)(dian)(dian)方式亦(yi)有所不(bu)(bu)(bu)同，有的(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)路(lu)的(de)(de)供(gong)電(dian)(dian)(dian)(dian)由幾塊穩(wen)壓管供(gong)給(gei)(gei)(gei)，如(ru)愛立信早(zao)期系(xi)列(T18之前)手(shou)機(ji)、部分三星系(xi)列手(shou)機(ji)等(deng)。有的(de)(de)卻有一(yi)塊電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)模塊直接供(gong)給(gei)(gei)(gei)，如(ru)摩托(tuo)羅拉系(xi)列手(shou)機(ji)、諾基亞系(xi)列手(shou)機(ji)等(deng)。但不(bu)(bu)(bu)管怎樣(yang)，如(ru)果(guo)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)IC不(bu)(bu)(bu)能正(zheng)常(chang)工作(zuo)(zuo)，就有可能造成(cheng)手(shou)機(ji)不(bu)(bu)(bu)開機(ji)。對于電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)IC，重點是(shi)檢查(cha)其輸出(chu)的(de)(de)邏輯(ji)供(gong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓、13MHz時鐘供(gong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓，在(zai)按開機(ji)鍵的(de)(de)過程(cheng)中(zhong)(zhong)應(ying)能測(ce)到(不(bu)(bu)(bu)一(yi)定維持住)，若(ruo)測(ce)不(bu)(bu)(bu)到，在(zai)開機(ji)鍵、電(dian)(dian)(dian)(dian)池供(gong)電(dian)(dian)(dian)(dian)正(zheng)常(chang)的(de)(de)情況下，說明電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)IC虛焊(han)、損壞。目前，越(yue)(yue)來(lai)越(yue)(yue)多的(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)IC采用(yong)了BGA封(feng)裝(zhuang)，給(gei)(gei)(gei)測(ce)量(liang)和維修帶來(lai)了很大的(de)(de)負擔，測(ce)量(liang)時可對照電(dian)(dian)(dian)(dian)路(lu)原理圖在(zai)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)IC的(de)(de)外圍電(dian)(dian)(dian)(dian)路(lu)的(de)(de)測(ce)試點上進行測(ce)試。若(ruo)判斷電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)IC虛焊(han)或損壞，需(xu)(xu)重新植錫、代換，這需(xu)(xu)要(yao)較高的(de)(de)操作(zuo)(zuo)技巧，需(xu)(xu)在(zai)實(shi)踐中(zhong)(zhong)加(jia)以(yi)磨練(lian)。

4、系統(tong)對鐘和復位不正常引起的不開(kai)機

系統時鐘是CPU正常工作的條件之一，手機的(de)(de)(de)系(xi)統時(shi)(shi)(shi)鐘(zhong)(zhong)一(yi)般采用(yong)(yong)13MHz，13MHz時(shi)(shi)(shi)鐘(zhong)(zhong)不正(zheng)常，邏輯電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)不工作，手(shou)機(ji)不可能開(kai)(kai)機(ji)。13MHz時(shi)(shi)(shi)鐘(zhong)(zhong)信號應(ying)能達到一(yi)定(ding)(ding)的(de)(de)(de)幅度并穩定(ding)(ding)。用(yong)(yong)示(shi)波(bo)(bo)器測(ce)13MHz時(shi)(shi)(shi)鐘(zhong)(zhong)輸出端上(shang)的(de)(de)(de)波(bo)(bo)形(xing)，如(ru)果(guo)無(wu)(wu)波(bo)(bo)形(xing)則檢測(ce)13MHz時(shi)(shi)(shi)鐘(zhong)(zhong)振(zhen)蕩電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)壓(ya)(對(dui)(dui)于13MHzVCO，供電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)加到13MHzVCO的(de)(de)(de)一(yi)個(ge)(ge)腳亡，對(dui)(dui)于13MHz晶振(zhen)組成的(de)(de)(de)振(zhen)蕩電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)，這(zhe)個(ge)(ge)供電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)一(yi)般供給中(zhong)頻(pin)(pin)IC)，若有(you)(you)正(zheng)常電(dian)(dian)(dian)(dian)(dian)壓(ya)則為(wei)13MHz時(shi)(shi)(shi)鐘(zhong)(zhong)晶體(ti)、中(zhong)頻(pin)(pin)IC或13MHzVCO壞。注意，有(you)(you)的(de)(de)(de)示(shi)波(bo)(bo)器在(zai)晶體(ti)上(shang)測(ce)可能會使(shi)晶體(ti)停(ting)振(zhen)，此時(shi)(shi)(shi)，可在(zai)探頭(tou)上(shang)串接一(yi)個(ge)(ge)幾十皮法以(yi)(yi)下的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)容(rong)。有(you)(you)條(tiao)件的(de)(de)(de)話，最好使(shi)用(yong)(yong)代換法進行維修，以(yi)(yi)節約時(shi)(shi)(shi)間，提高效率。13MHz時(shi)(shi)(shi)鐘(zhong)(zhong)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)起(qi)振(zhen)后，應(ying)確保13MHz時(shi)(shi)(shi)鐘(zhong)(zhong)信號能通過電(dian)(dian)(dian)(dian)(dian)阻(zu)、電(dian)(dian)(dian)(dian)(dian)容(rong)及(ji)放(fang)大電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)輸人到CPU引腳上(shang)，測(ce)試CPU時(shi)(shi)(shi)鐘(zhong)(zhong)輸入腳，如(ru)沒有(you)(you)，應(ying)檢查線(xian)路(lu)(lu)中(zhong)電(dian)(dian)(dian)(dian)(dian)阻(zu)、電(dian)(dian)(dian)(dian)(dian)容(rong)、放(fang)大電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)是否虛焊或無(wu)(wu)供電(dian)(dian)(dian)(dian)(dian)及(ji)損(sun)壞。另(ling)外，有(you)(you)些手(shou)機(ji)的(de)(de)(de)時(shi)(shi)(shi)鐘(zhong)(zhong)晶體(ti)或時(shi)(shi)(shi)鐘(zhong)(zhong)VCO是26MHz(如(ru)摩托羅(luo)拉V998、諾(nuo)基3310手(shou)機(ji))或19.5MHz(如(ru)三星(xing)A188手(shou)機(ji))，產生(sheng)的(de)(de)(de)振(zhen)蕩頻(pin)(pin)率要(yao)經過中(zhong)頻(pin)(pin)IC分頻(pin)(pin)為(wei)13MHz后才(cai)供給CPU。復(fu)位(wei)信號也是CPU工作工作條(tiao)件之一(yi)，符號是RESET，簡(jian)寫RST，諾(nuo)基亞乎機(ji)中(zhong)用(yong)(yong)PURX表示(shi)。復(fu)位(wei)一(yi)般直接由電(dian)(dian)(dian)(dian)(dian)源(yuan)IC通往CPU，或使(shi)用(yong)(yong)一(yi)專用(yong)(yong)復(fu)位(wei)小集成電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)。復(fu)位(wei)在(zai)開(kai)(kai)機(ji)瞬間存在(zai)，開(kai)(kai)機(ji)后測(ce)量(liang)(liang)時(shi)(shi)(shi)己為(wei)高電(dian)(dian)(dian)(dian)(dian)平。如(ru)果(guo)需(xu)要(yao)測(ce)量(liang)(liang)正(zheng)確的(de)(de)(de)復(fu)位(wei)時(shi)(shi)(shi)間波(bo)(bo)形(xing)，應(ying)使(shi)用(yong)(yong)雙(shuang)蹤示(shi)波(bo)(bo)器，一(yi)路(lu)(lu)測(ce)CPU電(dian)(dian)(dian)(dian)(dian)源(yuan)，一(yi)路(lu)(lu)測(ce)復(fu)位(wei)。維修中(zhong)發現，因復(fu)位(wei)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)不正(zheng)常引起(qi)的(de)(de)(de)手(shou)機(ji)不開(kai)(kai)機(ji)并不多見。

5、邏(luo)輯電路不正常(chang)引起的不開機

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。手機在使用中經(jing)常會引起機板變形，如按(an)按(an)鍵、摔、碰等(deng)外(wai)力原因(yin)會引起某(mou)些芯片(pian)脫(tuo)焊(han)，一般補焊(han)或重焊(han)這些芯片(pian)會解決大部(bu)分問題。當重焊(han)或代(dai)換正常的芯片(pian)還不(bu)能開機，并且(qie)使用免(mian)拆機維修(xiu)儀(yi)讀寫(xie)也(ye)不(bu)能通過時，應(ying)逐個測(ce)量外(wai)圍(wei)電路(lu)和代(dai)換這些芯片(pian)。

6、軟件不正常引起的不開(kai)機

手機在開機過程中，若軟(ruan)件(jian)通不過就會(hui)不開機，軟(ruan)件(jian)出錯主要是存(cun)儲器資(zi)料不正常，當線(xian)(xian)路沒有(you)明顯(xian)斷線(xian)(xian)時，可以先代換正常的碼片、版本或重(zhong)(zhong)寫軟(ruan)件(jian)，有(you)的芯(xin)片內電路會(hui)損壞，重(zhong)(zhong)寫時則(ze)不能通過。重(zhong)(zhong)寫軟(ruan)件(jian)時應將原來資(zi)料保存(cun)，以備應急修復。

7、其它原因引起的不(bu)開機

手(shou)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)不(bu)(bu)開機(ji)(ji)(ji)(ji)(ji)(ji)(ji)故(gu)障的(de)原因還有(you)很多，如液(ye)晶顯示屏不(bu)(bu)良(liang)、元件(特別是功(gong)放)短路(lu)等都有(you)可能引起(qi)手(shou)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)不(bu)(bu)開機(ji)(ji)(ji)(ji)(ji)(ji)(ji)，還有(you)一些機(ji)(ji)(ji)(ji)(ji)(ji)(ji)型(xing)必須用(yong)到(dao)32.768kHz的(de)實時(shi)(shi)時(shi)(shi)鐘(zhong)作為碼(ma)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(bu)(bu)正常(chang)，也可能造成(cheng)手(shou)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)不(bu)(bu)開機(ji)(ji)(ji)(ji)(ji)(ji)(ji)。引起(qi)32.768kHz時(shi)(shi)鐘(zhong)不(bu)(bu)正常(chang)的(de)因素主要有(you)時(shi)(shi)鐘(zhong)備(bei)用(yong)電池短路(lu)、32.768kHz時(shi)(shi)鐘(zhong)壞等。所(suo)以(yi)，在維修手(shou)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)不(bu)(bu)開機(ji)(ji)(ji)(ji)(ji)(ji)(ji)時(shi)(shi)要結合(he)具體(ti)電路(lu)具體(ti)分析，只要對手(shou)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)的(de)原理理解正確，思路(lu)清楚(chu)，不(bu)(bu)開機(ji)(ji)(ji)(ji)(ji)(ji)(ji)故(gu)障一般都可以(yi)排除。

手機開不了機如何解決

第一步：檢查(cha)電(dian)(dian)池是否(fou)有電(dian)(dian)，電(dian)(dian)池沒電(dian)(dian)了，手機(ji)自然沒有動力去開機(ji)，如果怎(zen)么沖它(ta)都不(bu)會(hui)啟動的話可以檢查(cha)一下充(chong)電(dian)(dian)器是否(fou)工(gong)作，接口是否(fou)損壞，用萬能充(chong)充(chong)電(dian)(dian)或檢測電(dian)(dian)量。

第二步：檢查電(dian)池是(shi)否損壞(huai)或者壽命(ming)已到，電(dian)池是(shi)消耗品(pin)，如果損壞(huai)或者使用(yong)不當導致電(dian)池過(guo)早損壞(huai)，可(ke)以嘗試換一(yi)塊電(dian)池，看(kan)一(yi)看(kan)是(shi)否可(ke)以啟動，如果問題(ti)解決，就需(xu)要更換電(dian)池。

第三步：進(jin)水或刷(shua)機造成人為性(xing)損壞(huai)，這(zhe)種問題就(jiu)是自身的原因了(le)(le)，進(jin)水的話用吹(chui)風機吹(chui)一(yi)吹(chui)，拆(chai)機烘烤試一(yi)試，如果摔壞(huai)了(le)(le)，內部零件損毀，就(jiu)需(xu)要找維修中心維修了(le)(le)。如果刷(shua)機造成無法開(kai)機，可以重(zhong)新(xin)刷(shua)機嘗試恢復(fu)。

第四步：如果基(ji)本的方法(fa)都嘗(chang)試過了(le)，還是無(wu)(wu)效(xiao)的話，就只能去找專業的維(wei)修(xiu)中心來進行維(wei)修(xiu)，一般無(wu)(wu)法(fa)開機的故障自(zi)己不好解(jie)(jie)決(jue)，也可以試試搜索(suo)，看看有(you)沒有(you)適合你的解(jie)(jie)決(jue)辦法(fa)。

手機開不了機怎么刷機

這里介紹最簡(jian)單的(de)刷機(ji)方式：一(yi)種(zhong)是使用軟(ruan)件下載ROM一(yi)鍵在線刷機(ji)！另外(wai)一(yi)種(zhong)是把(ba)ROM復(fu)制到(dao)SD卡里面然后(hou)進入(ru)recovery模式進行(xing)刷機(ji)！

1、用軟(ruan)件(jian)一鍵在線刷機(ji)：

步驟一(yi)、這個(ge)需要安(an)裝(zhuang)(zhuang)一(yi)款刷機軟件，這個(ge)軟件用的(de)人也非常的(de)多，還有(you)一(yi)件ROOT的(de)功能，刷機也需要ROOT。我們百度搜(sou)索“卓大師”，然后點擊下載安(an)裝(zhuang)(zhuang)。

步驟二、然(ran)后(hou)我們在進(jin)入自己的(de)手機，點擊設置(zhi)，然(ran)后(hou)點擊開發人員選(xuan)項。把USB調試打(da)開。不同安卓版本(ben)的(de)手機打(da)開的(de)位置(zhi)也不一樣。自己在設置(zhi)里面找找就能看到(dao)。

步驟三、然后(hou)把手(shou)機(ji)用數(shu)據(ju)線連接(jie)(jie)好(hao)電(dian)腦，然后(hou)在打開安裝好(hao)的(de)卓大師，卓大師連接(jie)(jie)手(shou)機(ji)成功之后(hou)點(dian)擊ROM專區。這里面會有很多手(shou)機(ji)的(de)刷(shua)機(ji)包(bao)。找(zhao)一個適合自己(ji)機(ji)型的(de)刷(shua)機(ji)包(bao)下載。

步驟四、然后在按照上圖的(de)指示(shi)，點(dian)擊下(xia)面的(de)下(xia)載(zai)狀態，打開之后就會(hui)看到ROM下(xia)載(zai)的(de)位置(zhi)。

步驟五(wu)、然后把你下(xia)載的(de)ROM的(de)壓(ya)縮文(wen)件復制出來。這個(ge)文(wen)件也可(ke)以直接(jie)復制到SD卡里面進(jin)入recovery模式進(jin)行刷(shua)機(ji)，下(xia)載刷(shua)機(ji)包(bao)是最(zui)重(zhong)要的(de)。而且刷(shua)機(ji)包(bao)呀下(xia)載適(shi)合自己機(ji)型的(de)，不然很容易變磚。

步驟六、下載完之后(hou)會出現(xian)刷(shua)機(ji)的按鈕，或者(zhe)我們進入(ru)導航里面的一鍵刷(shua)機(ji)，選擇好刷(shua)機(ji)包點擊(ji)下一步，選擇是否備(bei)案(an)，然后(hou)點擊(ji)下一步就坐等刷(shua)機(ji)成功提示啦(la)。

2、Recovery模式刷機(ji)方法：

步驟一、首先要確定你的手機是否刷入(ru)了Recovery，如果沒(mei)有的需要刷入(ru)Recovery才(cai)能進入(ru)Recovery進行刷機。這(zhe)里后(hou)續在為大家演示(shi)刷入(ru)Recovery的方法。

步驟二(er)、然后(hou)我們在進(jin)入設置把(ba)USB調試關閉(bi)掉(diao)，把(ba)刷機包復制(zhi)到你的(de)SD卡里(li)面。關閉(bi)了USB調試才能讀取(qu)出來你的(de)手機內存。

步(bu)驟(zou)三、然后在進(jin)入(ru)recovery模式(shi)，進(jin)入(ru)recovery模式(shi)的按(an)鍵有的不一(yi)樣。有的可以從電腦控制進(jin)入(ru)recovery模式(shi)，有的按(an)著(zhu)開機鍵+音量(liang)鍵就(jiu)能進(jin)入(ru)recovery模式(shi)。進(jin)入(ru)recovery模式(shi)之后先清除所(suo)有的數(shu)據。
