restore mo new version dol wag na downgrade ok naman ang 16.3.2 na ngayon...
 
:) HELLO, gusto kitang e help pero marunong ka na ba bumasa ng schematic diagram kahit basic lang ? para magets mo ung sasabihin ko
 
ito ung mga need ko na dapat nagawa mo na muna:
by the way bago mo gawin ito,, sure kaba na no display? or baka pag na inilawan mo ng flashlight ung screen may makikita kang image ?

*ilan ang draw ng current sa charging using product schematic or kahit anung supply na may digital display.
*Kung meron kang boot cable, gusto ko malaman ilan ang current niya,, nag iinitialized ba ung phone kapag power on mo ?
*or kapag naglagay ka ng supply via boot cable, atleast set mo sa 3.8v ung dc bench, kumakain ba agad ng ampere kahit hndi mo pa na power on ?
eprovide mo lahat ng info na yan.
