You just need to toggle some settings

You need to go to downloads (usually found under tools) than go to settings and there you should find mobile data limit select unlimited and you are done

[Upgrading, Modifying and Unlocking] shobithshetty:
not sure what went wrong :(

So anyways i installed TWRP and loaded the miui 7, everything was good but for some reason google contacts werent syncing !

So i went and googled as always and saw that i had to download some google launches from mi store from baidu.

For some reason while it was installing the felt stuck and so i switched it off, turned it on, BOTH sim's not detected.

I went back to recovery, cleaned formatted and re-installed the MIUI 7 system but still dosen't detect both my sim's :(

sometimes detect's sim 2, sometimes dosen't...not sure what to do now ??:(

Please Help :(

Thanks,

Shobith Shetty
[Upgrading, Modifying and Unlocking] RAGHAV RT:
Same here bro

Some times IT SHOWS NO SIM CARD DITECTED IN YOU PHONE
[Upgrading, Modifying and Unlocking] shobithshetty:
Work around ?

I just realised that if you shut down the phone and then switch it on, sometimes it detects your sim.

It dosen't work when you restart the phone. And there is a chance that it will detect one SIM only, so try experimenting with both SIM 1 and SIM 2, both cards and 1 card only...you might be able to get a small fix.

Thanks

There are quite a few stable custom roms for Coolpad Dazen 1.

I personally use MIUI 8.0.2.0 by dhanvate.

Gapps is integrated into the rom itself. No need to flash Gapps zips.

Everything is working fine except for Tap to Wake screen. If you can forgo this feature, the rom is good.

I use Jio and I don't lose signal in MIUI 8.0.2.0 and battery backup is good (average SOT of 5hrs 30 mins on continuous usage / browsing / music/ youtube/. All of this on Jio 4G network.

I use Amplify, Greenify, SdMaid, Appops, Lspeed and Titanium (freezing unneeded system apps) for extending battery life.

Hey guys is there any way to play pokemon go in this rooted rom. It is showing os not supported
[Upgrading, Modifying and Unlocking] :
But as per the Indian Laws, imei changing/tampering/swapping even with ones own imei number of another phone is illegal.

Here's some quotes from the Internet which are taken from reputable indian websites.

" Tinkering with the IMEI (International Mobile Station Equipment Identity) number of your cell phone could put you in jail for three years. Not only that you could be fined as much as Rs 2 lakh."

" An IMEI number is a unique code given to a mobile phone that helps in easy and accurate identification of the device. But off late, new software have been invented that allow people to tinker IMEI numbers of a mobile phone that makes it difficult for law enforcement agencies to track the concerned device.

In 2009 itself, the Indian government had banned the import of mobile phones without IMEI numbers into the country. Last year, TRAI (Telecom Regulatory Authority of India) had also asked the government to ban all devices with fake IMEI number"

"Swapping the IMEI Number even with a person's/relative's other personal mobile device is also not allowed as per the Indian Laws.This was also reported by TRAI"

So sir you see that Imei swapping even by taking permission and using friend's IMEI is not allowed.

Moreover sometimes you get IMEI Error if you change the IMEI which is not preferred by many people.

I APPRECIATE YOUR EFFORT TO COME UP WITH A UNIQUE SOLUTION BUT SIR WE HAVE TO COME UP WITH A NEW, SAFE AND MORE EFFECTIVE METHOD.PLEASE TRY TO UNDERSTAND.WE ALL ARE LIKE DEVELOPERS AND WANT TO IMPROVE OUR PHONE COOLPAD DAZEN 1 TO HELP OTHERS.

Hope you have understood.

PLEASE CHECK OUT THE SOLUTION I HAVE GIVEN TO GET THE FM RADIO WORKING IF YOU ARE USING MIUI 7/CM 11.

I am sure the you are more knowledgeable than me and will come up with a new solution. :D

Thanks

[Upgrading, Modifying and Unlocking] sonnu0100:
GUYS let me explain you some points.

Those app are not real imei changer , they are just xposed modules which mask your imei from the apps installed .

Its your right to protecr your privacy . There ia no rule that that you have share youe real info with the app.

The legal rule is that you can not change imei number as when something bad happen telecom company can track you via imei ..

These imei apps doesnt change ( correct word is mask/hide) imei with your telecom operator .

There is no legal issue in using it .. Some apps even helps you to change all settings like xprivacy which provide options for changing all info .. They just provide a random/ fake info of phone when the information is acessed.

Real imei of the phone is stored in read only chip ( yes we can change via some specific software but m not going to discuss those ) . These real values are not changed by these apps.

Hope this imei issue is clear now .. Use those xposed modules freely .

Hit THNAKS if somebody helps you.
[Upgrading, Modifying and Unlocking] :
But can the telecom operator track the imei if we change the imei using those software? Also we sometimes get imei not valid issues.
