I need unlocking lg u890 - LG enV VX9900 Cellular Phone

I had a lg u890 mobile phone that i got unlocked but it had the same proble where i swithched on my phone it used to ask for the usim code..my old phone was locked to the 3 nt/wrk i got it unlocked so i could use my 3 nt/wrk sim card or any network simcard but i used vodafone 3g sim card.the code i used with my vodafone 3g network simcard in phone when switched phone on & it asked for usim sim code i inserted code i got & it shut the phone down then on again then it wld work with vodafone no bother at all it even came up with vodafone uk etc.but i had to reconfigure the sms/text telephone number aswell as reconfigure the mms settings & numbers etc aswell as reconfigure wap settings from 3g network to vodaphones.but after i got it all unlocked & settings changed etc & inserted a different 3g network simcard ie vodaphone/orange/o2/3g sim/t-mobile/tesco sim/virgin sims & switched phone on it asked for usim code i tryed the code i have & inserted the same code i have it/they switched phone off & then back on & all network usim card worked with no problems at all.the code i have is.>>> 142358#*# thats 142358# * # all 1 item/action.once you insert that 142358#*# thats it your phone will shut down then restart up & go onto the network usim card you want to use or inserted before using code.but 1 thing tho please remember if u switch off your phone or your phone switches off as batterys run out no power u will need to insert the code again.& another thing code wont work if your phone switches off or you switch it off & plug your mobile battery charger into phone to charge your battery up on the phone & you switch you phone back on when you are charging your phone as the phone will switch on & say insert usim code if you enter the code the phone will switch off & back on again but it will still request usim code.so you will have to wait unto there is plenty of charge in the battery to take phone off charge & swithch your phone on get the usim code message insert code above phone will switch off & straight back on again & then it will go onto your prefured usim card then you can plug your charger into phone again to charge phone up.you can use your phone on charger when u have entered usim code & it switched off & on again & registered with the prefered network.i hope this is of use to you as it is to me.if you try this code & either if it works or not please can you let me knows ty.email [email protected]
