A review
Old post( made on 18th July 2015)
Thanks a lot! any idea if/when our device will get its own forum on xda? What about a codename, like redmi 1s is known as Armani. And do you plan on making this cm11 as official by submitting it to them?
Edit(8-8-2015)
Okay I'm editing this useless post and adding some info to make it useful because a lot of people are gonna be seeing it, since it's on the first page.
I flashed this rom about a week ago and this is the most stable rom for this device. It is pure and simple Cyanogenmod. No unneeded extra bloated features gotten through hacking and what not. Nope. Simple and pure cyanogenmod. And that's why it runs smooth as butter. Let's talk point wise about some things.
1) Battery- For me, the most important thing about a phone is its battery life. If it is plugged in half the time, what's the use. A mobile is supposed to be mobile. This rom has great battery life. It gives a screen on time of 7 hours. Read that again. Not overall time. Just the screen on time of 7 hours. Over all time can easily go upto 3 days if you use it for 2 hours every day. I'm a heavy user though and it lasts me a minimum of 7 hours. This is as good as the stock Miui rom and the developer has done this without the kernel sources, so thumbs up to him. Be sure to thank him by pressing the thanks button.
2) Ram - It's a 1GB ram phone. At least that's what I'm using. So dont expect the performance of a flagship from it. If you use greenify and hibernate all useless apps, you wont face a single lag or stutter. I always have around 300-350 mb ram free after installing around 120 apps. All of them are greenified, except whatsapp, hike, alarm clock, nova launcher and swiftkey. I'm a greenify freak. Whatever you do, be sure to greenify facebook and chrome because they hog a lot of ram.
3) Sound/Music - I was very surprised by the music quality that this rom provides. It's loud and clear as the Miui rom. To get such clarity and quality in an early build of a custom rom and that too without kernel sources is a miracle. Kudos to the dev.
4) Camera - Now we are talking. :victory: Everyone is concerned about the camera. Well the stock camera is not good and it doesnt take pictures as good as the Miui rom camera. But not to worry, go to page 4 or 5 of this thread and you'll find the apk of cyanogen camera linked there. Download it and install it normally. It works quite good. It also has the option of time lapse video which is quite nice. But some of you might not like even that camera. So search for "Miui camera port for cyanogenmod" and you should find a miui forum link where the zip file is present. Download the file and flash it via recovery and voila! you'll have that awesome camera back again. PS - It's not the miui 6 camera, its miui v5 camera. PPS - It was originally intended for Redmi 1s but it works very good on our device. The name of the file is MIUICamera44-4.zip and its size is 2.2 mb.
That's it people. This is an awesome rom and i havent faced any bugs till now. I cant even imagine using that horrible miui 6. Xiaomi makes great hardware but poor software. Installing cm11 makes our device high on steroids. :highfive: Enjoy the rom. I will update the post later if i feel like adding some more info.
Dont forget to thank the developer for his hardwork by pressing the thanks button. Thanks me too, if i helped you.

CM most likely won't accept devices on CM 11.0. I'm still waiting for official kernel source release before starting to work on CM 12.1.

This forum is really just a list of threads with a particular tag. Every thread with the tag redmi-2 will appear here. Still waiting for an official forum from XDA [emoji14]

O,no. The codename sounds terrible. I think it should be another one.

Feedback：It seems like everything works great except for Power-off Alarm.

HM201481x is the actual codename of the device.
I've just released a new build with a fix for proximity (for those who had issues with it before).

---

Good to finally see this rom here in xda,thank you so much for your work.BTW on your latest build and i can confirm that the proximity now works perfectly.
Waiting for CM 12.1 build.

Yep, and due to this proliferation of codenames... it will be a mess understand which ROM is for which Redmi 2.
As an example: is this ROM for HM2014813? or just 11 (which is the most common one?)?
Can we share the best practice over at miui.com forum by stating in the title the code of the device the ROM is made for?
For the people out there:
- Device code is written on the phone, below the battery slot
- 2014811 is the 1GB RAM model
- 2014813 is the 2GB RAM model
Thanks!!!

That isn't true actually. 2014813 is just 2014811 with different bands. 2GB models have another codename altogether (either that or they have the same codename). Anyway, my ROM works on all Redmi 2 variants, except that it will change your model to 2014811 once flashed.

---

Thanks. Power-off Alarm still has not been solved yet. Looking forward to your next version.
Redmi 2

I'm looking for a new phone, and the Redmi 2 made it to my shortlist, but I would like CM on it. When I buy one, it will be a 2GB HM2014813 (they are actually advertised with this number) because of the bands supported.
When you say this ROM will change the model to 2014811, do you mean it just changes the modelnumber in the software, or does it also change the supported bands to the ones of the 2014811?
Also: are there any known non-working parts like in other ROM's?
Thanks!

The ROM only changes the model number. Your phone still acts like a HM2014813.
The ROM is pretty much bug-free; I have been using it as my daily driver since the first release.

Hi, does this ROM works on Redmi 2 Enhanced (2GB ram,16GB internal) version?
