This is a guide with resources about to install CyanogenMod 12.1 on UMI eMax mini

This guide is created by UMI (original grammar), I just added the link to the TWRP install tool created by me

The development of Rootjoy compatibility of UMI eMax mini is still in progress

The process described in this guide is quite complicated and needs special attention. So, I recommend it for experienced users only. If you miss to create at least a working backup, your phone might be permanently bricked.

You are warned!

Howto flash CM12.1 of EMAX MINI?

<1> Install Driver
1.    Insert USB cable, inDial-up interface input “###2324#”to open COM Port, make sure you can seethe COM Port in your computer

Well, the creator of this tutorial is definitely not an expert. I've provided it here (since it came from UMI) however, I'm sorry to say that but I didn't take the effort to work with this crap and my mind won't change in the future.

A s far as i know rootjoy is not fully compatible with the emax mini yet , you can still use some of the features but not flashing a rom. I wish there was an easier method to do this . Umi should not be advertaising  the emax mini with cm12.1  that was the only reason I went with the emax mini and not the tcl i though there was going to be more support

Unfortunately, your request is not a possible way. A recovery update can only update an existing firmware but can't replace its whole content. Reconstructing the flash tool application would be a possible and acceptable way, since that's still quite a simple and safe method of updating and that contains all parts of the firmware.

Ignore the rawprogram0.xml, i think its a typo in the instructions. Just select the rawprogram0_unsparse.xml and after that the patch0.xml. Then click download and thats it.

New problem, Anybody having trouble installing apps?  ...

I was having trouble installing apps on playstore too, with the CM12.1 rom provided by Umi - same 504 error. Once I've tried another rom I could install any app from playstore.n

I'm on Mokee now. The only thing that was not working was the clock app - I couldn't set an alarm, it force closes. I had to install it from the playstore, and deactivate the system clock app - wich I prefer since it has the shake to stop the alarm option.

Some minor problems, like led notifications and tap to wake up not always work proper, but overall it's working great! Hope to see more development for our phone, and CM13 shortly. : )

I keep thinking why our phone doesn't perform as it should - lags and stuttering. How can Xiaomi Mi4i, which has the same specs, scores almost 40000 on antutu, and our phone hardly scores 30000? Could this be related to the roms? How could that be fixed?

One think I've noticed is that the internal storage is real slow, compared to other phones. Did some androbench tests, and the results were poor, compared to my Samsung S3 Neo and with Xiaomi Mi4i. I'll attach some photos to show the differences. Changed i/o settings, but I could not improve the results.

I answered questions of multiple users in my last post.
Did you try to install the twrp created for TCL M3G? Link: http://www.needrom.com/download/twrp-recovery-for-m3g/
The twrp provided by me works perfectly with original UMI ROMs but I haven't yet tested it with TCL ROMs. The different partition structure can cause problems.

Edited by seniorbp49 at 2016-1-13 21:16 \n\n Edited by seniorbp49 at 2016-1-13 21:15 \n\nMaybe it would have been simpler to modify (update) the  uploaded Needrom version to make it useful instead of this very complicated routine which higyly increases the probability of "mistake and brick". It seems too risky to me int htis way.
Even better: Maybe UMI could come up with original updates fot our phone - instead of forcing this hacking.

On Needrom we can find this ROM - I think the sane version (according to date 2015.09.16)

It is written under the introduction:

"UMI confirms that CM12.1 ROM is unusable, DO NOT INSTALL. Wait for the update" – is this still valid ?
What is the present situation ?
I am confused.

1. I already have an installed TWRP + rooted phone (following former instructions)  
can I just flash the cm12.1 zip after the usaual wipes ?

2. Where can we see a review about this version of cm12.1 - or is it stock ?
This would be helpful before deciding.

Thanks for post - but I am still looking for UMI.

Just for my personal interest: What's the difference between your instructions here and just installing a ROM over Custom Recovery?
'cause for me it looks like you just install TRWP on a very complicated way (Step 1 to 5) and after that you flash the ROM over TRWP (Step 6)

And furthermore:
Is the ROM correctly converted for the EMax Mini?
If somebody tried this guide, I would love to read some experiences with it.

Thanks for your work again, Ben!

Oh, sry. seniorbp49 was a little bit faster.

Yes, it is the same version. The QCN backup-restore makes it useful with the eMax mini.

Yes, after flashing the content of the Q39_zhongxing_20150717.zip file and restoring your original QCN file, you can install any kind of TCL M3G recovery updates.

1. No, you can't install this CM12.1 or any other versions without transforming your phone into a TCL M3G. Flashing the content of the Q39_zhongxing_20150717.zip file makes that job done. After that process, you have to restore the original QCN backup of your phone, since the baseband is the difference between the two models and that part of the firmware is not included in recovery updates.

2. This stuff comes directly from UMI, so we can treat it as an official release in cooperation with TCL. That's already declared, both the hardware and software of this model are developed by TCL, so this is a legal use of their works here.
