Le dejo los paso que utilice para hacer imei sin ningun problema, lo hice con el firmware que traia el celular "G570MUBS8CTB5_G570MUUB8CTA1" y salio a la primera...
Pasos:
1. Activamos depuracion usb y con chimera le sacamos rmm prenormal.... (verificamos oem abierto una vez encendido)
2. Ponemos el cel modo descarga y le pasarmos Twrp(desactivar reinicio auto en odin), forzamos reinicio con vol- y power... ni bien se apaga presionamos vol+, home y power... para entrar a twrp
3. Vamos a wipes y le damos a format data... yes ... volvemos al inicio y vamos a install... por micro sd u otg instalamos Magisk-v19.1
4. Reboot to system y do not install... esperamos que encienda y verificamos OEM abierto y dep usb...
5. Reparar con chimera... y luego parchar... sale con fritas!!!
Verificado 100%!!!
