hello,
i recently installed miui7 on my dual sim mtk based (mtk6592t) smartphone.
it does work very well, but the second sim slot lost the bands for umts/wcdma connections.
before the update, both the slots were capable to find and connect on 3g network
now only sim1 slot can connect to 3g
in mtk engineering mode i see that only these bands are now available on sim2 slot:
GSM MODE
EGSM900
DCS1800
PCS1900
GSM850
Instead on sim1 slot i have also the UMTS MODE:
WCDMA-IMT-2000
WCDMA-GSM-900
with stock rom, the UMTS MODE was available also on sim2 slot, and i could connect to 3g networks
How can i fix this problem?
Thank you.

Dear all, I have M8sd China telecom version. Flashed M8st Rom to try and working but no 4g. So tried pressing *#*#4636#*#* and selected USA Band. No signal detected. Factory reset and restored M8sd backup didn't help. Still without any signal. Please help!
I Have the same problem
I have enabled other band selection (other than USA and 800mhz) from the unlocking band in the Sony thread. Chosen Euro band and is working normally now.

Hi, not sure about CDMA. but i unlock gsm using the following adb command. you can try if it works for cdma:
adb shell
su
setprop persist.radio.simlock.enable 0
reboot your device
Btw, is your phone working with lte in your country using the cooked rom base on m8 and unlock band method?
Thanks @ftorres
I already tried to install custom rom but i only found GSM - GSM rom and they are working both sim cards GSM but no CDMA - GSM rom till now only the stock rom and I am asking if I will found rom CDMA - GSM or another way to hack the stock rom please see the attached images to see the error message with stock rom.
B. Regards,
I receive the same msg as yours. But I think the notification is for 4g card. That's why I could not connect to 4G network. Didn't know that CDMA network could not connect as well. Couldn't help anymore if you've tried. Think CT is blocking other card inserted to slot 1. Maybe need someone that can disable the check on the sim card slot 1 to bring us forward. Sigh...
I am still searching for that thanks
It works with me by restoring the Indian rom by TWRP backup
Did this work? You got an MEID and everything?
EDIT: Oh got it yours already had CDMA support officially.
take a look at this thread

Hello
I have THL W8S smartphone. When I bought it, it had a possibility to choose which SIM I can use for 3G service.
There is a quote from the device's guide:
'WCDMA cards can be identified in both SIM1 and SIM2 card slots and connected to 3G network.'
However, After I flashed the smartphone to a new firmware (from 102 to 106) I can use 3g only on SIM1. I tried flash back 102 firmware but it didn't help.
Please, help me with a good advice how I can get a possibility to switch 3g to SIM2. Have I change a modem driver? If yes, could you advice a correct modem driver etc.
Many thanks in advance.
Hi there,
Either ask in the ROM thread you got the firmware from or since we don't have a forum for your device in the Questions and Answers section.
