Hello!
I have 2 sim cars (the first one is M, the second one is B). Yesterday, I go to 4636 menu and changed something. After that for the 1 slot is working only with M simcard and only in 4g mode (network 2g and 3g can't find), the 2 slot is working in 2g mode with internet. When I changed the simcards M -> 2 slot, B -> 1 slot. M is go in to 2g mode, the B can't find network tottaly. Also I did a factory reset which didn't help. What can I do?

Hello, I need some help. I have the d802 model of the LG G2 and I have a problem: in order to use 4G I have always to go on the phone app and type the code *#*#4636#*#* then a menu opens and I have to go Phone information and then Set preferred network type and finally select LTE/WCDMA/GSM. But he problem is that this setting always reset when I restart the phone or even randomly (It always go back to WCDMA preferred), so I can't use 4G anymore.
Ps: Even while LTE/WCDMA/GSM is selected I'm not able to select 4G at Settings > Tethering & networks > Mobile networks > Network mode, but it still works
Ps 2: I'm using pure stock 4.4.2 KitKat ROM
Ps 3: I did hard reset the device
Ps 4: My mobile service is Claro, from Brazil
Anyone please?

Hi everyone, I'm new to this forum.
I purchased a Moto X Play a couple of days back, everything was working fine till today morning when I was struggling with getting 3g network on 4G/3G preferred mode. I decided to change the preference in phone setting using*#*#3646#*#*.
Upon trying different options it remained stuck to gsm only mode, so I tried clicking "turn radio off" a few times which would make the signal go and come back in a few seconds but suddenly I lost network in sim 1 and have been trying everything for last couple of hours but won't get the signal back. I even tried swapping the sims and using a different sim but network in slot 1 is still off the radar. In the sim setting the phone would show the sim but there is no network. Any help in this regard will be highly appreciated.
Thanks

get modem.bin file at this page, and flash it.
fastboot flash modem modem.bin
fastboot erase modemst1
fastboot erase modemst2
I'm not sure but you don't have to unlock your bootloader for this process, so your warranty will be ok. i think.
Do I need a pc for this process or it can be done on phone itself? Can u plz share some step by step tutorial as I am a novice. Also please tell me if there is some simple method to do this without using a pc.
Update: the ROM in above link is for single sim model while mine is a dual sim model.
I am having redmi note 3G 2013121 which was booting only in recovery mode. So I flashed it using SP tool and FASTBOOT ROM 7.5.2.0.KHDMIDE, but accidentally I used option Download+Format due to which I lost my IMEI number and NVRAM.
So I rooted the phone and loaded the IMEI with help of MTK DROID ROOT & TOOL.
Now My phone detects the SIM shows the operator name but no signal. I tried flashing MIUI 6, MIUI 5 but I am not able to fix it.
please help on same.
Also I loaded the NVRAM from other device 2013121 but still I am not able to fix the issue
Also when I search network manually it shows no network found or some times TATA DOCOMO 2G is shown
I tried Airtel and Vodafone Mumbai networks
Hello. i have a weird problem with my Tab A6. My tablet functioned with my LTE sim (MTN network) until my uncle used the tab for a while with his Vodafone network sim. after retrieving the tablet back the device does not recognise MTN LTE sims (tried 4 different sims) anymore. It however recognises 2G/3G MTN sims and the sims of other networks. when i insert the LTE sims it reads "No Sim Card" emergency calls only but works well in another similar tab.
The device is not rooted and running Android 5.1.1. and a baseband version T285XXU0AQD1. i have factory reset it even in recovery mode but the problem still prevails. i need help. thank you
