[Moto G 2015 General] squid2:
I had spent many hours examining LED notifications on osprey. Unfortunately, we are held back by a hardware difference beteen surnia/lux and osprey. All of the Motorola devices equipped with stml0xx sensor hub were originally equipped with a notification LED that could be controlled by both the sensor hub and the power management IC.

Earlier this year, Motorola decided to drop the LED notification feature and removed the capability from the kernel. This decision was made about a month after the design of the production surnia hardware was completed, and a month before production osprey hardware design was complete. As a result, the hardware for LED notifications controlled by the sensor hub was left in on surnia, but the relevant traces and resistors were removed on osprey. They probably did this to reduce complexity, and it may have saved them a tenth of a cent per device on resistors. They didn't remove the trace on lux, perhaps because it had gone out of mind by the time they were paying attention to production lux hardware, or perhaps because they realized that it was useless to do so, and would only limit the capabilities of the device.

The consequence of this is that the LED can only be controlled through the PMIC on osprey, while it can be controlled by the PMIC or sensor hub on surnia and lux. The sensor hub was designed to support LED notifications, and can run the LED arbitrarily. The PMIC is physically designed to only provide power to the LED driving circuit when a charger is plugged in.

Unfortunately, as a result of this hardware limitation, I don't think it will be possible to have LED notifications with the device unplugged on osprey.
[Moto G 2015 General] arnabJ:
Thanks for clearing the clouds.

Is it possible to fake plugged state?

If yes than may be it will be possible to make it work as expected.
[Moto G 2015 General] StrangerWeather:
Hey there, no worries, it only took about 5 minutes to write the tutorial. I said it was "experimental" because it is not a properly functional hack. It's just a bit of fun for people who like messing around with Tasker. I happen to find it useful, but like you, I would much prefer for the led to be fully functional. I really miss this from the Moto G1. ;)
[Moto G 2015 General] squid2:
It's possible to fake being plugged in software, but I don't think it's possible to fool the PMIC into thinking it's plugged in software. Even if it were possible, that would result in strange behaviour as the PMIC would try to charge the battery when no charger is plugged in.
[Moto G 2015 General] krsmit0:
He just said it was a hardware limitation. Convincing software its charging won't tell hardware to provide the led power.
[Moto G 2015 General] arnabJ:
Thanks for answering my curiosities.

I read that. What's wrong in asking though if it's possible some other way round?

How about battery life?
[Device Reviews and Information] cinephile79:
Worth mentioning that the rear cam is a Sony Exmor RS and front cam a Samsung.

Also, the screen is made by Sharp.

The battery is a 3050mAh and the rom is expendable to 32gb

It's a TCL Meme Da 3S (TCL M3G 3S) clone since TCL and Umi seem to be working together now

Very interesting phone for $150US

I might order one, except that it's only available in white for now. What do you think?

The band-problem (800MHz) of the UMI Emax is still not fixed?? Sad, I hoped they would fix it...

Megthebest - great review, thanks for that! But two questions:

1. You wrote, it's not possible to install apps on SD-Card - isn't it pre rooted, so you can use Link2SD for that procedure?

2. Did you test RootJoy? Because UMI said with RootJoy you can install the newest CM on the UMI Emax Mini.
[Device Reviews and Information] megthebest:
800mhz band is not fixed yet.

Stock rom comes without root, and you may have to install twrp (chinese/english) and try if with sulersu you can work with link2sd and ext partition on sd.

I have not tested rootjoy yet, i will check today

Hi there,

Nice reviews within this thread. One question. Does anyone experienced extreme heating on heavy usage? If not, I think I will order this, even if it does not have band 20. It seems I can obtain quite good reception with 1800 and 2600mhz. Furthermore I like the possibility for Cyaonegenmod.

Update: Just ordered one - Now let's hope I did not made a bad choice :).
[Device Reviews and Information] Just_a_fan:
It would be nice, if you report about your experience with the EMAX Mini and installed Cyanogen Mod on it.

And just one Question to all - it's written in the most reviews, the Emax Mini IS pre-rooted. But megthebest wrote it isn't - whats true?!
[Device Reviews and Information] FJP84:
I will do that, but I still waiting for to be delivered. I may switch my order, because there could be a lot of issues bricking this phone. But that also can be the challenge ;). Maybe in a couple of weeks more info is provided to correctly flash TWRP and CM12.1.

Keep you posted!!
[Device Reviews and Information] Vojkostar:
Hi

umi emax mini is NOT pre-rooted.

anyway, android version is a lot cleaner than samsung etc... so it is not bad phone ( for 129$), and i like it somehow.

i am missing LTE band 21 ( i think it is 850 MHz or something below 900). so G4 is useless in our country for now
[Device Reviews and Information] Jochie11:
Pre-rooted with Rootjoy

Hi all,

The Uni Emax mini has a kind off root. Rootjoy by Umi. Hopefully (for me) this is work in progress because I cannot install TWRP, CM12 or anything for which I need root. I think the problem is that you cannot get into fastboot. ADB works, but fastboot somehow not.

I got in a bootloop, but that was easily repaired with the instructions found on umi + rootjoy.

No problems with heat, but I am not a poweruser.

Battery-life is great for me.
[Device Reviews and Information] Vojkostar:

[Device Reviews and Information] DocSoton:
Mine arrived today... seems great for budget device. Little disappointed as had read was shipping with 5.1.1and CM would be available but neither are the case... just hope the latter is true as would be great to have official CM support.
[Device Reviews and Information] FJP84:
I received my phone a week ago and I am very pleased. It is holds realy well in my hand, very nice screen, very good battery life, good connectivity (Wifi, Bluetooth, GPS, 3g and even 4g is working great outside in almost every area I normaly be).

Phone is getting warm when gaming, but is not overheating. Some new games like FIFA16 UT can stutter a bit, but FIFA15 UT is working fine. Gaming is not my priority so thats all fine.

Rooting the phone is very easy, with no bloatware what so ever. On the Umi community forum someone created a perfect tool for windows to install the Windows drivers, and to flash TWRP. It was all done in just a couple of minutes. After that I flashed Supersu 2.56 zip in TWRP. And now my phone is rooted.

Also there is an rom update available that can be downloaded and flashed using the flash tool provided on the same forum. I did not tried that yet, because I have a working device and theterings seems not to work in that rom. It is reported to Umi.

I will follow the progress on a CM based rom actively. I hope it will be available in the near future.

If there are any questions please be free to ask

TCL M3G roms work just fine.

1. Get root

2. Do QCN backup in QPST (in terminal "setprop usb.sys.config diag")

3. Flash LEWA 4.0 using QFIL

4. Root LEWA and flash TWRP

5. Restore modem backup (QCN)

6. Flash any ROM for TCL M3G.

CM12.1 is working.

Thanks pbPACMAN from 4pda.[IMG="cm12.1 Umi eMax mini"]http://i.piccy.info/i9/928b52107b789c02272904e10aeed827/1450894619/267033/918625/IMG_20151223_191109.jpg[/IMG]
[Device Reviews and Information] FJP84:
Hi, thanks for sharing this. Couple questions.

1. What is QCN, QPST and QCN.

2. Where do I get Lewa 4.0

3. How to root Lewa? Is it possible to first flash TWRP and flash Supersu using TWRP. I already have TWRP. Do I need to flash it again after flashing Lewa. Or can I use TWRP to flash Lewa in the first place.

4. What TCL CM12.1 rom did you have installed and what is your opinion of the performance.
[Device Reviews and Information] varotone:
Hi, where did you find QFIL-flashable image of LEWA 4.0? Only LEWA I can find is a recovery zip.

EDIT: nvm, found it in 4pda (can't post link because newbie)
[Device Reviews and Information] Shandry:
Oh, it's hard to describe in one post.

First, you need to get root, e.g. using this for PC: http://www.iroot.com/

Download QPST from here.

QCN backup can be obtained similar to this instructions: http://sanfranciscoandroid.co.uk/an...-qpst-and-backup-qcn-orange-san-francisco-ii/

Enter this in terminal "su setprop usb.sys.config diag" and phone should switch to Diagnostic Mode. That's why you need root.

Do a modem backup before flashing LEWA!

Here is Lewa 4.0 QFIL image.

LEWA ROM is supposed to be flashed via Download Mode (Power + VolUP, as I remember). You will need QFIL software from QPST package to flash it.

By doing this Umi Emax Mini will be converted to TCL M3G (same phones, different brands) .

Root for LEWA, TWRP for LEWA, newer TWRP for LEWA with ability to backup modem partition, for installation from recovery .

You will need another TWRP for TCL M3G. After flashing LEWA ROM you will get factory like TCL M3G without custom recovery and root.

Restore QCN backup after flashing LEWA.

I used this CM12.1 based ROM + Nano Gapps

Original link: http://bbs.tclmobile.com.cn/thread-27518-1-1.html

Performance is good. Battery holds quite well. Not worse than with original ROM. I didn't run any tests, but phone is working fine and stable, without any problems. No freezes or reboots, everything is working like it should, stable.

All credits go to Chinese community http://bbs.tclmobile.com.cn/forum-138-1.html

Good luck.
[Device Reviews and Information] varotone:
Hi again,

Which drivers did you use for QFIL? My phone in download mode shows as "QHSUSB_BULK" in device manager, and QFIL shows "No ports available"...

EDIT: I was again too quick to post, used drivers from UMI Unbrick Kit successfully

---------- Post added 27th December 2015 at 12:01 AM ---------- Previous post was 26th December 2015 at 11:08 PM ----------

Alright, here's my experience:

- Flashed LEWA with QFIL

- LEWA doesn't boot, stuck at kernel logo

- Flash TWRP using fastboot

- TWRP keeps *****ing about being unable to mount /data

- Flash CM12.1 via TWRP

Current state: bootloop, and every 3 or 4 loops, the phone enters TWRP by itself, executes a script, and bootlops again.

I am baffled.
[Device Reviews and Information] Shandry:
Hm, interesting. What TWRP you are using?

Did you try to do a factory reset in TWRP?

Try this TWRP. It is working for me.

Also, did you try to refresh LEWA in Download Mode? It definitely should boot.

Here are checksums for LEWA that works for me.

File: LeWa_TCL_M3G_Flash_15.07.15.15.zip

What ROM you are flashing?
[Device Reviews and Information] varotone:
I succesfully flashed YiOS after formatting (not wiping) the data partition, it seems that TWRP not being able to mount /data was the cause of all my problems.

Interestingly enough, with this new phone configuration I have been able to flash the CM12.1 for eMax Mini, the one that has since been taken off the UMI forums.

Note: deleted links from quote to avoid spam filter.
[Device Reviews and Information] Shandry:
Great! Do you know why they took it off? I did not notice any problems with M3G version of CM12.1. Maybe little problems with minimum auto brightness in the night, screen starts flickering when phone gets hot.
[Device Reviews and Information] varotone:
They took it off because it bootlooped with stock eMax Mini configuration. That makes the fact that it boots with this "m3g" image particularly interesting.

Anyway, I can't seem to put my phone in diagnostics mode now, my device manager shows it as "Android" with an exclamation mark, which is weird because I had no problem to use the diagnostics mode in UMI stock rom.
[Device Reviews and Information] Shandry:
Check ALCATEL HS-USB Diagnostics 9092 in COM and LPT section.

I also have driverless Android device, it is not diagnostic port.

Do not forget to activate USB debug!

EDIT: Actually, this makes no difference. Looks like Diagnostic Mode works just fine without usb debug.
[Device Reviews and Information] varotone:
Nope, nothing in the COM section. It appeared in UMI stock rom after setprop, but not now, it is pretty weird.
[Device Reviews and Information] Shandry:
Do you have clearly working root access?

Try to update SuperSu.

What happens when you enter "su" in terminal?
[Device Reviews and Information] varotone:
I did have root access (latest supersu), and su through adb shell worked perfectly, it was just the diag mode which seemed to not work.

I have since resorted to reflashing Lewa through QFIL. It booted this time, and diag mode worked in Lewa, so I restored the QCN backup.

Currently I am trying the eMax Mini cm12.1 available at needrom, and everything seems to be working.

Edit: I am having a weird bug in any rom I try: wifi and data work, but the icons in notification bar always show an exclamation mark over them. Additionally, Play Store installs always fail with error 920. Could I have restored the modem backup incorrectly?

Edit 2: Play Store error 920 was solved by using other Gapps. The other bug remains: when I first boot up the phone, wifi and signal works fine, but if I turn off wifi, both wifi and data show exclamation marks (even if they're working).

Edit 3: It kinda goes away after a while? I am very confused
[Device Reviews and Information] Shandry:
It is easy to check in About phone -> Status -> IMEI information. If Something goes wrong while restoring QCN backup there will be no IMEIs.

For me WiFi is working perfectly fine.

You have too many problems :D. I do a factory reset, then I flashed YIOS ROM in TWRP with latest nano GAPPS. Everything starts working right after flashing and continues to work after reboots.

You can try to use TWRP/ROM/GAPPS combination that I mentioned in previous post. It is tested by me and works 100%.

Here is it
[Device Reviews and Information] varotone:
Nah, IMEI is fine, I have working data and wifi. It's just that notification icons don't seem to work very well.

I tried YiOS and it worked fine (also pretty cool rom), but it's only in english and chinese (i need spanish) and the english is missing translations in several parts...
[Device Reviews and Information] FJP84:
Thanks for the detailed information. I will gather all the tools and so. But I am a little bit reserved by transform it to the m3g. So I will watch this thread for more information and experiences first.

One question: I already have TWRP and root. Will this interfere with the steps you mentioned.
[Device Reviews and Information] Shandry:
Yes. It is a first step. Actually, you do not need TWRP, just root. Root access is needed to do QCN backup. Conversion procedure erases modem firmware (at least partition with settings), but with QCN you can restore it.

There is modified TWRP that can do a modem backup for UMI EMAX MINI. Do not know if it's working with TCL M3G or not.
[Device Reviews and Information] Saschimi:
Shandry, thank you for your explanation and all the links!

I just got all the needed stuff together and will give it a try. I´m not an expert or developer but I have some experience in rooting and flashing. It might take a few days, but I will share my experience.

May I ask you two questions?:

Why is the QPST-Backup so important? (I´ve never worked with it.)

Is it necessary to use the linked Lewa-Rom and if yes could you explain, why?

Best regards,

Saschimi
[Device Reviews and Information] Shandry:
You are welcome, Saschimi.

UMI EMAX MINI is based upon Qualcomm chipset. Qualcomm has own software for programming and flashing their chipsets. With QPST you can reflash firmware(QFIL) and tuneup modem settings. It is especially useful for CDMA phones as you can change almost anything, even ESN (somewhat relative to MEID -> IMEI ) in some conditions.

But with great power comes possibility to mess up things easily.

When you are doing conversion from UMI to TCL, TCL firmware flashes own modem firmware and resets modem settings. Without backup you will end up with bricked modem. So no calls, no data, even no IMEIs in About Phone menu.

Looks like you can restore modem setting using Unbrick Kit from UMI website(Newer tried it). But it is always better to have a backup than fix errors.

Yes, because it is full QFIL image. With all environment, partitions and settings to ensure correct operation. You may imagine it like TWRP backup of all phone partitions, including sections that are not easily available to flash: boot, system, splash, recovery, etc. Just look at internal structure of theLeWa_TCL_M3G_Flash_15.07.15.15 QFIL image.

Theoretically, conversion can be done using other methods, e.g. we can try to create modified TWRP image to flash all this things. But I do not have time for such experiments.
[Device Reviews and Information] Shandry:
Discovered working USB host in the umi emax mini. Nice.
[Device Reviews and Information] Saschimi:
Hi and happy new year! :silly:

Thanks again, I´m ready to go but stuck at a first very noob question:

You wrote to type in terminal "setprop usb.sys.config diag" - that´s meant to be in linux, right? But I found QPST only for Windows available. So do I have to use Wine, will it work with the phone connected? Or is there another solution to get the eMax Mini into Diagnostic Mode? (< btw, is this FTM?)

Sorry, more than one question :angel: but your help is very much appreciated because there are many other users in a German forum who request your procedure...

Apropos, I have Windows 10, LinuxMint 17.2 and OS X 10.9.5 all 64 bit available.
[Device Reviews and Information] varotone:
That's meant to be in Android, via a terminal emulator in the phone, or adb shell.

The process should be done entirely in Windows. If you're using Windows 10, you will need to enable installation of unsigned drivers in order to use the ones available here.

I've written an extensive tutorial on how to do the whole process, but it's in Spanish. If you don't mind that (or trust in Google Translate), it's here. I might get around to translating it someday.
[Device Reviews and Information] Saschimi:
Oh man, sure, Android... :rolleyes: Thanks for clarifying, Varotone. :good:

And many thanks for the link to your tutorial, too. It definitely helps, even if I understand spanish only particulary.
