After formatting everything I formatted everything on SP Flash Tool Format All + Download and now, I experience problems on my device:


NVRAM WARNING: Err = 0x10 showing up on WLAN - Can someone help to fix?
Won't detect SIM, No SIM Card - Emergency calls only...
all other problems were listed here... Well, edits removed it because they were fixed


Yeah... The third bullet said it, there were other problems but they were fixed thanks to me, and sometimes, the internet. Well, there are still two problems that are still not fixed.

SIM detection is broke, yeah, probably after I fixed IMEI. Any help with that? Thanks.
NVRAM WARNING: Err = 0x10


this seems to be an issue caused by tinkering with deep system internals, I'm no expert in lenovo phones, I use samsung, but in my knowledge, I remember that NVRam is really delicate, is there another tool for flashing your phone? any means to get a complete firmware of it? by this I mean the following:

In the case of samsung phones, you usually flash only a part of the rom, because NVRAM, Bootloader and other system-internal parameters are not truly necessary for just flashing a ROM, however if you have messed around with the radio system (cellular part), or the wifi/bluetooth/etc. firmware (and by this I mean that particular chip's firmware, not the android fW), you will need a full-firmware, which contain all these system related files.

In your case, if you don't know where nor how to flash these special partitions/fw's back to your phone, I encourage you to do what @acejavelin posted and take your phone to a specialized tech service.

HTH!
