Uma sihambela kwelinye izwe, enye yezinkinga esingase sibhekane nazo ukuthi ifoni yethu ayihambisani nama-band atholakala kuleyo ndawo. Kodwa-ke, uma sinefoni ye-Android eneprosesa ye-Qualcomm , lo mkhawulo ungadlulwa kusetshenziswa uchungechunge lwemiyalo.
Isibonelo, eNyakatho Melika, amaza e-GSM asebenza phakathi kwamabhendi angu-850 no-1900 MHz, kanti eYurophu kusetshenziswa amabhendi angu-900 no-1800 MHz. Lokhu kusho ukuthi asazi njalo ukuthi idivayisi yethu izosebenza noma ngabe siya kuphi, okubangela ubuhlungu obukhulu. Kodwa-ke, ezimweni eziningi, lo mkhawulo usetshenziswa ngesofthiwe, ngakho-ke ungasuswa kalula. Uma usebenzisa idivayisi eneprosesa ye-Qualcomm enale mikhawulo, ngenxa ye-XDA ungayisebenzisa noma kuphi emhlabeni. Yonke inqubo ichazwe ngokucophelela kumhlahlandlela wezinyathelo ezingu-36, futhi ngemva kokuyilandela, ifoni yakho ye-Android kufanele isebenze noma kuphi emhlabeni ngaphandle kwezinkinga.
Ukuze senze le ndlela, kumelwe sikhumbule izinto eziningana. Okokuqala, kumele isetshenziswe kudivayisi egxilile efakwe i-terminal emulator . Okwesibili, kuyinqubo eyingozi engenza ifoni yakho ingasebenzi, ngakho-ke asinacala nganoma yimuphi umonakalo obangelwe ukwenziwa okungafanele kwesifundo. Njengokujwayelekile, sincoma ukuthi wenze isipele sedatha yakho ngoba, njengoba sizobe sisebenza "nomsakazo," singawusebenzisa idivayisi yakho ye-Android. Ngalezi zinyathelo zokuqapha engqondweni, ake siqhubeke nezinyathelo zesifundo esithuthukisiwe:
- Landa le zip http://dh.st/0Me
- Khipha futhi ufake i-QPST ku-zip
- Vula uhlelo lokushaya bese udayela * # * # 8778 # * # * (kufanele liphume ngokuzenzakalelayo ohlelweni ngemva kokumakwa kwenkanyezi yokugcina)
- Xhuma i-Android yakho kukhompuyutha.
- Vula ikhonsoli ye-ADB.
- Faka imiyalo elandelayo:
I-shell ye-adb
su
setprop persist.usb.eng 1
- Vala ukulungisa iphutha le-USB bese unqamula ifoni yakho kukhompuyutha yakho.
- Linda imizuzwana embalwa bese uvumela kabusha ukulungisa iphutha le-USB ku-Android.
- Xhuma kabusha ikhompuyutha kukhompuyutha, lapho kufanele izame ukufaka amanye abashayeli. Linda kuze kuhluleke ukufakwa kwalokhu.
- Vula isiphathi sedivayisi futhi uzobona imodeli yedivayisi yakho izikhathi eziningi. Iya kunketho ethi "Imininingwane", skrolela phansi futhi uzobona "isigaba" MI_0x.
- Phequlula kulawo madivayisi uze uthole i-MI_04.
- Khetha "Buyekeza umshayeli" bese ufake umshayeli we-HTC ku-zip esiyilande ngaphambilini.
- Cindezela okuthi Qala bese uzulazulela ku-QPST -> Ukucushwa kwe-QPST.
- Buyela emuva kumphathi wedivayisi bese ubheka Amamodemu -> I-HTC.
- Thola imbobo "COM *" (kungaba COM1, COM2, COM3…, kuya ngekhompyutha yakho).
- Ekucushweni kwe-QPST chofoza okuthi "Engeza imbobo entsha", ukusetha imbobo kusuka esinyathelweni sangaphambilini. Ngelebula (ilebula) bhala igama olifunayo, njengemodeli ye-smartphone yakho.
- Zulazulela ku-QPST / bin bese uvula i-RV_NV_Manager.exe
- Chofoza ku-Setting -> Comport bese ukhetha imbobo yakho ye-COM.
- Khetha Ifayela -> Funda kokubekwe.
- Sicela ulinde ngesineke ukuthi inqubo iphele futhi unake!
- Iya kulayini 1877 bese ukopisha inombolo yedesimali ukusuka kwesokudla uye kunoma iyiphi iphrosesa yamagama.
- Yiya endaweni lapho ukhiphe khona i-zip esinyathelweni sokuqala bese usebenzisa i-mzTool.
- Ngakwesokunxele uzobona "Input radix", lapho kuzodingeka sibeke inombolo yedesimali yangaphambilini.
- Ngakwesokudla uzobona "RF BC CONFIG", lapho kuzodingeka sinamathisele inombolo ekopishwe ekuqaleni ku-RV_NV_Manager.exe
- Manje usuzokwazi ukubona amabhendi ifoni ekwazi ukuwasebenzisa, ikakhulukazi "kulwazi oluncane".
- Shintshela kuthebhu ethi "Band preference (i-NV Value)".
- Khetha wonke amabhendi e-GSM nawe-WCDMA atholakalayo. Uma kwenzeka uyazi ukuthi zisebenza kanjani, khetha labo obathandayo.
- Ngemva kwalokhu, kopisha inombolo yedesimali ukusuka kwesokudla esingezansi.
- Susa wonke amakhoma enombolweni (",") ukuze wenze inombolo eyodwa.
- Vula i-RV_NV_Manager.exe lapho siyishiye khona (isinyathelo 23) bese unamathisela inombolo entsha ngaphandle kwamakhoma.
- Khetha bhala i-NV bese uya kokuthi Ifayela -> Bhala i-NV eshintshiwe endaweni yokubeka
- Vula i-emulator yokugcina ku-Android yakho bese uthayipha okulandelayo:
su
setprop persist.usb.eng 0
- Qala kabusha idivaysi.
- Thayipha, njengasezinyathelweni zokuqala, * # * # 7378423 # * # *, ukuze ubone wonke amabhendi ongawasebenzisa.
Njengoba ubona, lesi isifundo esiyinkimbinkimbi kodwa esiqondile kakhulu esizosivumela ukuthi sivule wonke amaza ku-SoC yethu ukuze sikwazi ukwenza izingcingo sisuka noma kuphi emhlabeni. Sithemba ukuthi ukuthole kuwusizo futhi, njengenjwayelo, sincoma ukuthi uvakashele isigaba sethu esizinikele.
