  1. Hello po.. gusto ko po sana itry 'to kaso everytime na icoconnect ko yung phone sa laptop via USB laging USB is not recognized by windows. any solution po na alam niyo? Installed naman na yung driver kaso may lumalabas na "USB not recognized (Device Descriptor Request Failed)" sa device manager.

  2. question lang po, may ways po ba na pwede e downgrade ang OS ng Flare J1 from Lollipop to Kitkat? like changing the system.img with the same chipset model from other phone with kitkat version? thanks.

  3. Idol yung sakin po after ko gawin yung preocedure nag black screen tapos pinabayaan ko lang, V2 ginamit ko ngayon di ko na po maulit yung process para sa V4… what should I do? nabuhay pero yung touch di gumagana…

  4. Sir na stock ako dun sa chinese recovery,pag yung last yung pinipili ko may nalabas na logo ng adroid tapos red exclamation mark.May translation po ba kayo nung chinese stock recovery kahit by words lang? salamat.

  5. Pano po e force shut down yung j1 ? Yung sakin po kasi na stuck up lang sa logo tapos pag nilong press ko yung power button mawawala tapos pag binitawan ko na bigla namang babalik . Hanggang logo lang siya ng Flare J1 . Patulong naman sa nakaka alam 🙁 . Ano pwede gawin 🙁 .

  6. BASAHIN PO NINYO NG MAIGI.. YUNG PROSEDURE.. GOOD PO SA AKIN ANG V04 .. YUNG V02 AYAW MAG GANA ANG TOUCH.. PERO OK NA DIN KASI YUNG V04 GOOD 1000000%

  7. YUNG IBA SANA D MAWALAN NANG PAG ASA. AKO NGA ISANG ARAW KO NATAPOS YUNG SA J1 KO.. NAKAKAPAGOD HEHEHE … TIYAGA LANG MGA KAIBIGAN. ^_^ ANG ALAM KO PAG ROGRAM ANG SIRA ..SA PROGRAM DIN MA SO SOLVE.. ^_^ SALAMAT ADMIN. MORE POWER! ^_^

  8. nagwork po sa akin thank u po.. na change ko na ung boot animation ko at sound. na uninstall ko na din ung mga google na d naman kailangan. at ok ok na ung memory ko mabilis ung phone kahit 512 lng ung ram ko.

  9. mga boss, salamat sa rom na ito.. narecover ko phone ko mula sa pagkakabootloop…
    ngunit meron pa po akong isang problema… ung storage nya is 256 mb lang.. dinawa ko naman ung additional instruction ng ilang ulit.. pero ayaw padin bumalik sa dati ung storage nya.

    salamat po sa tutugon!!!!

  10. Na solve ko n ung Problem tungkol sa 256mb internal Storage! Kso sa V4 q lng nasubukan! Lalo Pang lumaki Internal q Naging 2.29gb insted ok 1.95gb! Ganito lng gagawin! Makinig mabuti ok

    Press up and power hanggang sa lumabas ung chinese recovery! tapos punta sa pinaka baba using down volume! pag nsa pinaka baba na press up volume naman! pag lumabas n ung android n naka "Higa" just keep pressing up/down volume and power salit salitan! tapos may lalabas n Boot.. hanggang sa mapunta k sa Wipe/partition And Factory reset! Tapos i Wipe mo n partition at i Factory reset Then Reboot! Tapos W8 lng Loading Tapos Yun Okey n Na restore n J1 Internal Memory mo! Sana Makatulong! TY Godbless!

  11. sa mga nag flash ng v2 ( kagaya ko na end result is hindi ma touch yung screen — bale flash nyo lang v4 ).

    then once na flash na yung v4, malaki chance na hindi nyo mapasok ang recovery by pressing volume up + power button combination… try nyo to para mapasok nyo ang recovery.

    + make sure naka on ang unit nyo
    + then enable nyo ang debugging mode
    + open command line and dapat meron kayo adb na naka install
    + issue command like this :: adb.exe reboot recovery

    done… antayin nyo lang mag boot unit nyo sa recovery.

  12. sir rafael.
    ask khu lang poh kasi ung unit khu cm flare j1 V2,
    nung mag shutdownd poh xa d na poh xa ma open at d na rin xa nag chacharge d rin poh xa ma detect ng pc.

    panu poh ma fix poh ito?
    TIA.
