I cannot free nokia 5200 because of the version v5.53 on bb5 in spite of j' have flashe C nokia with plusior versions lower than 5.53 but the portable demare not normal

which tool u use for flash
(quel box tu utilise pour flasher)
when u flash u have to click downgrade and not flash boton
(tu tu flash a une version inferieur, tu doit clicker sur downgrade et non pas sur flash)

BR,

thank you for your answer but j' use HWKufs for flasher this portable but how I can dowgrade on the hwhkufs

you choose files that you want to flash on phone, MCU+PPM+CNT and u tick DOWNGRAD than u press flash
after finish flash u try unlock...
see attached pic
(regard l image attache, cocher DOWNGRADE puis click sur FLASH, biensur je suppose que tu doit flasher de la version 5.53 a une version inferieur qui est 5.00 c pour cela il faut cocher DOWNGRAD @+)
