Hi Sir, i have a doubt. If we flash lollipop custom rom, will the actual os change i.e, will it support 64 bit computing or just the UI ?

Hi,
Yes it will actual change the OS, lollipop not 64bit. 64bit it depend on your cpu or processor mtk so lollipop will run on 32bit processor. It pure lollipop not just the UI only

Ok. Thanks. So if suppose the SoC was MTK6732, it would support 64 bit. Right?

when you get stuck on android logo, first think you must do is try to factory reset your device from recovery mode and for your information firstboot can take approx 5 minutes

Restore using original backup or bring to lenovo store, because Lenovo S850 hard to restore signal after losing IMEI

Is there any way to get the network to be stable by compromising other functionalities?
Or will we have to wait until a new update is released for the rom ? If so , until when ?

Thanks in advance

Hi,
No there is no other way, you just need the update. Lenovo issue when change ROM or modified ROM is signal strength because lack of source resources so just need to wait the update. Until when, i dont know will update when new ROM is release
