No SIM cards are visible by phone after firmware burn - Android Q&A, Help & Troubleshooting

Dear XDA,
A phone Lenovo A858t has been burned with stock rom (A858t_USR_S302_1501111200_MP13V11_BMAIN_RU
) using SP Flash Tool (preloader checkbox was checked and Format ALL and Download was chosen in selectbox):
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
After burn no SIM is detected and no IMEI is being shown in settings.
Could anyone suggest what to do next and fix it?
Thank you very much, really
Best regards

Thank you very much! Worked!!!
One is interesting. When calling *#06# it shows two same IMEIs, but we've wrote different IMEIs for Phone 1 and Phone 2 as was suggested ( IMEI for Phone 1 + 8 ). Is that okay? ( Btw, signal exists for both SIMs and works dialling works )

No it is not good when you have same imei numbers , you must again to do the same proces :
look from here write two Original imei numbers which you can find on sticker below the battery :
Like for example
Imei 1: 359160070214058
write command
AT + EGMR = 1.7, "359160070214058"
Press SEND AT COMMAND
Imei 2: 359160070214060
AT + EGMR = 1.10, "359160070214060"
Press SEND AT COMMAND
Restart your device and check your IMEI .
WARNING !!! Don't use these imei numbers use your Original .
Good luck

Thank you, but where did you find second IMEI? Isn't it first IMEI with added 8? Like 359160070214058 +8 = 359160070214066 ?
Also, should we choose Phone 2 before sending command?
Thank you very much!

Hi , you didn't understand me , you don't need to add 8 like I said , just put 15 digits numbers (imei).
For One imei for First sim:
example (I will use this imei just for example)
Imei 1: 359160070214058
write command
AT + EGMR = 1.7, "359160070214058"
Press SEND AT COMMAND and reboot your device!
example (I will use this imei just for example)
For second imei Second sim:
Imei 2: 359160070214060
AT + EGMR = 1.10, "359160070214060"
Press SEND AT COMMAND
Restart your device and check your IMEI .
Of you still didn't understand here is some ov example what you need to do .
