Maybe your cellphone is blocked in your country? here in Colombia we have blacklist for reported IMEI's so maybe that's the problem, other thing you can try is to dial *#*#4636#*#* (INFO) and trying looking for more information about currier network on "Phone Info" section, you can try changing the preferred network type to see if you have any luck
[Xiaomi Redmi 2 ROMs, Kernels, Recoveries, & Other ] karthik km:
Yes you can flash prime ROM on your 1 GB variant
[Xiaomi Redmi 2 ROMs, Kernels, Recoveries, & Other ] Liquid2:
i think it most likely not the case...

i am from indonesia, and as far as i know, there is no such a thing like imei blocked...

there even a discussion about it and so far, and people already reported, yet, the operator cannot block using imei

only the sim card number can be blocked if reported...

now i on miui 8.1.3.0 lolipop suggestion from karthik km

based lolipop because i should on redmi 2 prime LP fastboot ROM, next try install lineage os again

and i tried *#*#4636#*#* and gsm service : radio off

cannot change prefered network and cannot turn on radio :(

this happen to my friend phone, redmi note 3 snapdragon, when using rom lower than 7.3.7.0, he also face the same problem

he tried using rom 7.2.x.0 so 4G can be used without any trick (here in indonesia, redmi note 3 SD officially not supported 4G because the law/rule here) so he force using 7.3.7.0 again and then flash 4G fix

just flash wt88047_pro_global_images_V8.1.3.0.LHJMIDI_20161230.0000.00_5.1_global_23ac47dab8.tgz to my redmi 2

and signal still no service :(

now, i just have to flash lineage os and gapps, right??
[Xiaomi Redmi 2 ROMs, Kernels, Recoveries, & Other ] karthik km:
Yes going ahead

If still no network

Then there is something wrong with your device

Does anyone know how to get the Netflix app to work?

The app is possible to download from Google Play but it will not start. Says the phone is not compatible...

Apparently they have implemented the Google SafetyNet API and it requires a locked bootloader to approve the phone. As far as I know you cannot run a custom OS with a locked bootloader and for the Redmi 2 the bootloader has always been unlocked, right?

Don't worry about that. Just on the magisk hide for Netflix. BTW can you attach the ss.
[Xiaomi Redmi 2 ROMs, Kernels, Recoveries, & Other ] NamitNayan:
But the app 'IRCTC next' doesn't open even after enabling magisk hide for it(says phone is rooted) .2 or 3 months before magisk hide made the app to work.

But on the apps like root checker when I enable magisk hide then root checker app shows my phone is not rooted(means magisk hide working fine)

https://xiaomi.eu/community/threads...-tried-all-tricks-maybe-hardware-fault.33024/

actually, this once happening to my friend redmi note 3 SD too, when trying downgrade his muiu 7.3.7.0 to 7.2.3.0 to make 4G available without any trick (in my country, indonesia, redmi note 3 SD 4G locked off because some rules/laws). it make the same like this. yet imei still present.

tried lower version, and still no signal...eventually he back to 7.3.7.0 which luckyly fix this problem...

oh, when first boot up, lineage OS can detect my region based on my sim card...so i am still guessing it is maybe not hardware problem, even though i am not 100% sure though...

next maybe i am gonna try changing my imei, to check if maybe this imei is being blocked or not...

anyway, is there a way flash redmi 2 using EDL mode?? tried "fastboot oem edl" in fastboot, didn't worked

Instagrams app's and others can't balance the light correctly, i used Instagram, Boomerang and QRcode from Scan and the image turn all black in a very bright condition and all white in a very dark condition.

[MENTION=5432026]nicknitewolf[/MENTION] sir please look into the heating and battery drain issue. It has been a long time since this issue is present. In the last CM14.1 nightly (20161225) this issue wasn't there (if this is of any help). In my phone (model: 2014818) all CPU cores are stuck at either 1.1 GHz or 1.2 GHz. Sometimes one core goes offline. I think this is the reason why the heating issue and the consequent battery drain is there. Love your work sir but cannot use it because of this issue. Hope you will understand. Thanks again!

Revert back to miui from any custom rom

To revert back to miui from any custom rom then Just wipe system, cache, dalvik cache and data in twrp recovery and then install latest stable or developer miui rom on your device. This applies to any Xiaomi device.

Watch this video to clear your doubts : https://youtu.be/04x0iJk5a7k

Tried but error 7 comes in TWRP
[Xiaomi Redmi 2 ROMs, Kernels, Recoveries, & Other ] Sahil Pulikal:
To solve error 7 problem in twrp, you should first check whether the rom file is supported by your device. For example, If you are flashing miui on redmi 2 then download miui rom for redmi 2 only otherwise you'll face error 7 in twrp.

Or else, make sure that you have the latest twrp for redmi 2.

Fix for battery drain and cpu usage issue

Hi, the cpu usage and core not switching off is due to a bug in a volte related process: ims_rtp_daemon

I have checked logcat and it was spammed with errors from that process.

The solution was found on this thread itself,but it may break your volte capability.

Solution:

Flash the universal volte patch v2,

Download link:https://www.androidfilehost.com/?w=files&flid=141072

Got it from this thread:https://xdaforums.com/redmi-2/themes/uni-volte-patch-t3530537

Ironic that this patch fixes the wrong problem..

Anyway now the cpu usage is back to normal,and no more heating.

Now i am getting good performance and battery backup,with deep sleep being >90% active. :)

This is a common problem in all custom roms since 6.0.1 marshmallow, lollipop din't overheat, I don't know what is wrong with the roms, 20 minutes of gaming on kitkat the gpu temperature is 59°C to 61°C, but in every nougat rom it goes from 64°C to 73°C here, I din't find a solution, so since I got this device I can't use any rom on in, becouse kitkat miui is laggy, lollipop miui has UI lag for me, custom roms overheat, custom kernel's get reboots, I tried send my device to warranity and they send me a new one, and guess what? I still have the same problems , I can't use this device for nothing, custom kernel's developers don't know what to do and ignore this issue, I tried asking help, no one helped, so i'm here, i'm using the latest build of this rom, the UI is smooth as hell, but if I play games, I get overheats, will I be like this forever?
[Xiaomi Redmi 2 ROMs, Kernels, Recoveries, & Other ] :
Probably. But overheating is expected when you make some heavy use of your GPU. KitKat was a very light OS compared to M and N it's normal it runs hotter.
[Xiaomi Redmi 2 ROMs, Kernels, Recoveries, & Other ] LuanHalaiko:
Yes, but this is not normal, there are worse devices than redmi 2 that have nougat by custom roms and they don't experince this problem, the temperature from kitkat roms to nougat is the same, there is something wrong with the thermal configuration for redmi 2 since marshmallow, also in lollipop there wasn't a noticible thermal throttle, but in thease roms the device lags so much when it overheats, but it is a stable overheat I would say, the temperature stays at 73°C and sometimes it lowers down to 68°C, I can't play games with thermal throttle, I hope that there is a way to disable it
[Xiaomi Redmi 2 ROMs, Kernels, Recoveries, & Other ] Rihhan:
For overheating problem I would say that I did not notice over heating in 1st Jan build of this ROM. It is around 50 degree everytime, some 45-55 degree. But on latest build its everytime (when in use) above 70 degree. So I reverted back to 1st Jan build.

So use 1st Jan build and check overheating problem is gone or not.

Hi!

Thanks for the amazing work!

Downloaded latest build 20170109 and clean flashed from last CM14.1 build

I'm having the same problems I was having with CM14.1:

-Gallery sometimes open, most of times crash

-Flashlight toggle from Quick Settings isn't doing anything; other flashlight apps work fine

-Default Camera app and Open Camera sometimes doesn't option to switch to front camera, sometimes the front camera is upside-down (changes with reboot)

-Alarms sometimes crash when between snoozes or if I open Clock when a alarm is about to set off. It's bad because if I don't manually open Clock or reboot after the crash, future Alarms won't set off.

-Song picker sometimes crash when choosing a ringtone.

I think that's about it, as I recall. Anything new I'll let you know and I would be very pleased if somebody has fixes for those problems.

Cheers!

Oh, I'm sorry for bothering you with my stupid and "useless" question about headphones. True, I should've checked the forum before asking my question. And I apologise for that.

And also, don't assume that people are less clever than you just because they ask a "silly" question. You should have patience with people who may not be as acquainted with the topic as you. Otherwise, applying the same erroneous reasoning as yours, I might infer that you are less clever than me bearing in mind that you're "just" a swing manager. Am I right? Have a good day you too!
