changing cid, and phone laguage, debranding
Ive got HTC One X and need to put into phone polish lang pack.
about my phone
version main: 4.18.401.2
And i want to flash it with "RUU_ENDEAVOR_U_ICS_40_HTC_Europe_1.29.401.12_Radi o _2.1204.127.19_release_271851_signed.exe" this firmware, what I need to do? I asked about it at other forum but no result they closed my topic... Do I need to do S-OFF or root to change the CID, and flash? Or just use fastboot command "fastboot oem writecid xxx" ? If I just need to use this command what cid should i write? If I have to to other stuff please link me to tourtorial how to do it.
Thanks in advance for response, best regards Wojtekson16
