Oukitel U7 baseband / Imei / sim card connection lost

Hi, I´ve just got a Oukitel U7. This is a MTK 6582.
And at first look seems "nice". My issues start when I insert a sim card. Then it loses the Imei and dont connect to sim card. When I remove de sim card, I have Imei again.
So, any one experienced something like this ?
I already rooted, make a Imei backup, restore it. Flashed with SPFT and nothing seems to work.
Some ideias would be nice...
thank you

try to flash with new update with spft on needrom.com

Why doesn't my phone detect sim card after flashing stock rom? imei issue?

I have a BLU vivo XL phone to which I have flashed a new rom using SP Flash Tool.
My sim card wasn't being recognized by the phone, and I noticed there was no longer an IMEI number assigned to my phone. There are two sim card slots, and I manually assigned the IMEI number for each slot using the apk Mobileuncle Tools.
The sim still isn't working, but when I check Settings>About Phone>Status>IMEI information, the IMEI for slot 1 and slot 2 both have numbers assigned now, however, there is another value for the IMEI SV(Slot 1) and IMEI SV(Slot2), i don't know what this is, but they both still say "unknown".
I am guessing that maybe I need to have both IMEI and IMEI SV numbers in order to use the sim card slots, but I don't know how to get it or what to try next.
Thank you for your help.

Help with Samsung Win i8558 IMEI clash!!!

Hello Win'ners
Please I have this Samsung Win i8558 I got from a friend and would like to use my both lines in it (Not actually as a smartphone as I already have a Note 4) Runs on 4.2.2 but here is the problem I have with the device!
If I insert one SIM card in either slots... It reads and gets signal for the Network SIM. (either Sim1 or Sim2)
But if I slot both SIMs in both slots... It would give a "No sim card" error even when it would shows the SIM Network names under "SIM Card Manager" in settings but would not detect signal.
So I put in one SIM in sim1 and checked the IMEI via *#06# and it came up. I put in one SIM in Sim2 and checked the IMEI and found out both slots uses the same IMEI number.
If I mount both SIMs at same time and check the IMEI , it would give "Null/Null"
Any help on how to solve this problem as I have 2 network SIMs I want to use on it.
Thanks.
SOLVED
I solved the issue by flashing a later build via Odin!
Now I need root!

mt6572 dual sim problem

I have myphone note 3 and i am not able to use sim card on it. Its xperia z5 repelica (mt6572) with flashlight on side of camera instead of below the camera. Sim was working fine then i tried to flash stock rom on it because rom was faulty ( i can't find one for myphone note 3, i used z5 clone firmware) which worked fine exept for i can't use sim on it anymore. Imei and baseband is not a problem as i can fix it easily.
The problem is that its a single sim smartphone, when sim was working sim 1 radio was off and sim 2 radio was on. After flashing rom or maybe using snwriter to write imei sim 1 radio turned on and sim 2 radio turned off. Now i can't use sim card on it because it uses slot 2 for sim which is turned off.
Is there anyway i can set sim 2 as default and turnoff sim 1? Any way to turn radio on for sim2 and off for sim1?

Hello,
Redmi 5 Plus it stopped to sim card detected, I have been read that this problem appears after the update.
I try to unlock bootloader for install new soft but one of the steps in unlock bootloader is to insert the sim card and start mobile data - but no sim card detected.
Any ideas?
Thanks.

Try different Sim card, mybe yours is damaged.
If new SIM card is not recognized, well you have 2 options:
— hardware issues
— Persist partition is damage.
For persist you can search XDA forum for solution.
Good luck.
