Hmm I've got one issue with new rom. Sound when watching clips is too loud, even if volume is set to minimum it is almost like on max.

I also think that volume on minimum is not the same if I go from max to min and if I move from mute to min.
[Android General] Sn4kes:
I've just installed OTA 2.3. Like 2.2 installation went without a problem.

Regarding volume problems that I had, I had to disable volume leveler in Dolby Atmos app and now it is ok.

I just received mine phone and I will test TWRP recovery first. Also if is successful, easier tutorial will be posted. Wait one hour please.
[Android General] miljenko:
Not working, do not flash
[Android General] Calugarar:
Thanks for the head's up and link!

Might i suggest to include in the tutorial a way to fix the device in case something went wrong?

OK, people. Custom made firmware for our phone is uploading to needrom and I hope it will be ready in few hours. It is stock firmware mod with Xposed and Gravitybox working, changed launcher, added GPS EPO files for Europe, cleaned some files, disabled swap, few things here, few things there. In the end working firmware with factory framework.

twrp

Thk's for this recovery, it work perfect for me.

For the moment i have tried backup and restore the same install and everything is fine.
[Android General] Megavolt2000:
Just received an OTA update. It said it is supposed to improve camera quality. Only difference I noticed so far is that I now can select 14mp in 4:3 as picture size. Did someone find out more?
[Android General] Calugarar:
I tried to apply the update as well but apparently something went wrong... Didn't reboot or anything.

Does anyone know how to fix this?

Edit:

I didn't apply the custom mods by miljenko or anything out of the ordinary.

Update:

Doing a factory reset and then trying to apply the OTA, does not work. Same issue.

Sent from my M6752
[Android General] miljenko:
I'm sorry you have this problem. Have you tried to make factory reset?

Firmware that I have uploaded is compatible with this update, also TWRP will install update without any problem. Only thing that you need to make after finished update is to re-enable Xposed. Also lock screen is set to "Slide" during update.
[Android General] Calugarar:
Yes I tried the factory reset, same problem. I was able to recover a log file from the OTA folder tho. Did let iOCEAN tech support about the issue as well, maybe they can squash the bug while it's fresh?

Anyway, next thing I'm going to try is to flash your modded ROM with the recovery, could you give me a link to it (the ROM)

please, i didn't find the modded one on needrom.com, just the stock one.

Edit:

Never mind, i see the link you posted previously, must of missed it before.

Update:

Welp i tried applying the update through ADB (SP flash crashes on Linux apparently) and apparently it couldn't install the update because of the following error:

"/system/build.prop" has unexpected contents. Installation aborted.

If anyone wants the update file, it's here.
[Android General] miljenko:
Activate SuperUser , mount system as R/W and copy my backed up build.prop (attached). I hope it will help you.
[Android General] Calugarar:
I tried it, it didn't work unfortunately. I captured two LogCat's one with all my apps installed and one after doing a factory reset and sent them to iOCEAN support, i emailed them yesterday and in the same day they replied telling me that the information (i previously provided here) was sent to an engineer. I'm curious on how well they will respond to this.

Anyway, i was curious does anyone else have battery draining issues or am I the only unlucky SOB that has it all? :)
[Android General] miljenko:
For me battery seems fine. Try to flash firmware from needrom using SP FlashTools, you newer know, maybe is is something in the sotware
[Android General] Calugarar:
I tried, it didn't work, i tried both SP FlashTools on Windows and on Linux and they didn't installed the rom on my phone, I even tried to do it step by step like the instructions on needrom.com so that i could flash the factory ROM again, and i couldn't do it. This is very puzzling to me, it isn't the first time i flashed a ROM on a device and I never had so many issues ....

What could prevent me from being able to flash SW on the device?

I stumbled on what i think is a service boot menu when pressing VOL- + Power when the phone is off but it's completely in chinese.

Could you provide step-by-step instructions on how to do this, maybe i'm missing something that's really obvious ...
[Android General] miljenko:
I will try to provide you with step by step instruction how to flash firmware on MTK

1. Make sure you have MTK preloader drivers properly installed. How to check: Open device manager, switch off your phone (remove and return battery just to be sure) and connect phone. For a few seconds phone will be in preloader mode and if you see yellow exclamation (or question) mark saying "MTK preloader" than your drivers are not installed properly.

DOWNLOAD MTK PRELOADER DRIVERS

Once you have drivers properly installed lets continue.

2.Download latest version of SP FlashTools

3.Load scatter file of the firmware you like to install, deselect preloader (first line) and press download button

4.Turn off your phone (remove-return battery to be sure)

5.Connect USB cable and flash should start (first red and than yellow line at the bottom of the window)

6.Green circle and new firmware is installed

I hope this will help you.
[Android General] Megavolt2000:
To answer Calugarar's second question, I noticed some strange battery behavior, too. Some times when I connected the phone to a standard USB 2.0 port on my notebook PC, the battery startet draining by 1-2% a minute instead oft being charged. Like the phone was trying to charge the notebook.
[Android General] Calugarar:
That is quite true, I noticed it today when i used my phone as a bootable install disk (long story short Windows decided to play dead on this Sunday) using this awesome app DriveDroid , with it being plugged in to a USB 2.0 port, the battery went down from ~80% battery to ~25% with the screen off.

Yes! I finally made it!

Somehow it magically worked, didn't do anything special maybe reinstalling Windows 8.1 did the trick somehow ...

I managed to install TWRP using the file provided by Hanuma and applying it with SP FlashTool and the scatter file and then installing the modded factory ROM provided by mijlienko which btw thank you both for your work!

Oddly enough, I still wasn't able to apply the FOTA update, it giving me the same error, I don't know what's happening but I do hope iOCEAN is on the case with fixing this, a little bit of feedback from them to the community wouldn't hurt IMO.

I'm going to post lower the files that i used to be replicated with the same success i had and to offer additional mirrors as when I grabbed them, it went slowly.

MTK Windows drivers - if you have problems installing them on Windows 8.1, follow this tutorial

[Android General] Calugarar:
For those that couldn't apply the FOTA, iOCEAN has released a SP FlashTool flashable ROM, you can get it from here or here, unzip the file, load the scatter text file from the unzipped folder , select firmware upgrade and you are good to go.

If somehow you are confused then follow their step by step guide. For more info go to their service page and search for M6752.

Happy flashing!
[Android General] miljenko:
New firmware for our Rock M6752. It is Chinese UniOS, beautiful as you can see on attached screenshots. Unfortunately only Chinese and English languages are included. Everything works, if you find some bugs please report and I will try to fix them. I'm not big developer but I will give my best.

Firmware DOWNLOAD

Flash using TWRP, make Factory Reset (Data, Cache and Dalvik)
[Android General] Calugarar:
Looks nice, will give it a spin as soon as i'll have some free time, probably in the weekend. Any extra features? It would be nice if you'd include a list of things, IMO.

Anyway, does anyone know if there are custom kernels for our phones? Latest factory update has improved a lot things like battery life, responsiveness, etc.

So i was curious if we could play with the kernel a bit :)
[Android General] miljenko:
I just did it from curiosity, anyway it is very good firmware but too round for my taste. Currently I'm in process of making "something" based on the stock firmware with some changes in the systemui and setting apk files. I have deodexed stock firmware and if somebody have artistic expression firmware can be skinned nicely. Definitely soon I will publish V2 of the firmware.

Regarding kernel, MTK have closed sources and only producers can make kernels. If we get sources, kernel can be built.
[Android General] Calugarar:
I'm curious to see what you done with the V2 of the ROM, keep up the good work.

As for the kernel, we should get sources when the Meizu M1 Note will be launched with Ubuntu on it. I didn't knew that Mediatek was so bad at complying with the GPL terms . . . Otherwise I would of voted with my wallet differently :) .
[Android General] Megavolt2000:
Did anyone of you see a battery/charging app that shows plausible values for current and voltage for the M6752? I am would like to find out if it is compatible to quick charge 2.0 accessoires.
[Android General] Calugarar:
Well as long as the Voltages are the same, i don't see why it wouldn't. The cable has to be thicker to deliver the necessary power.

Most accurate would be to measure with a multimeter. Or you can time them, how much time it took to charge from say 1% to 15% with stock charger and how much time it took from 1% to 15% from a quick charge 2.0 charger.

Unfortunately i didn't see anything in Engineering Mode that would lead to a hint if it's using a normal charger, mtk fast charge or quick charge.

If you have a quick charge 2.0 charger, it would be interesting to see the results you got.
[Android General] miljenko:
I don't know about direct compatibility, but if you compare voltages on Qualcomm certified chargers (photo attached) with bundled iOcean charger, they should be the same (compatible).
[Android General] Calugarar:
miljenko is right, quick charge 2.0 gives out more power than our chargers so you should be fine, i don't really think though that you'll be charging faster than with stock m6752 chargers, it'll most likely cap at the factory charge specs so you won't get the 1.5A @ 12V (18 W), you'll get 1.3A @ 12V (15.6 W).

General rule of thumb that i tend to go by with chargers is that if the Voltage is the same and the amperage is equal or higher, you should be good. Unless it's some weird pin-out thing.
[Android General] Megavolt2000:
I don't own a QC 2.0 charger yet, but I was thinking about buying a QC car charger. But those are not very common over here in germany, so I would most probably have to order one in the US.

I wrote an email to Iocean support and got an answer really quick. They wrote that charging IC in the phone and in the charger have to be compatible but they could not tell me if it will work ;)
[Android General] miljenko:
Then you will know only if you try. I have 2amps car charger and it is sufficient enough, no need for QC.
[Android General] Calugarar:
Well in worst case scenario you'd have a normal car charger, but I think it'll use the Mediatek PumpExpress tech as well.

Maybe this would be cheaper? I think it's shipping from DE.

Or you could wait a bit for accessories to come out, i see that on Aliexpress there's already some cases and batteries for our phones.

If you do end up buying a QC charger post results! :D
[Android General] Calugarar:
Welp I tried different apps with different chargers and all I can say is that the apps aren't reliable at all, so you can't really test out chargers with the current apps from the Playstore.

In other news, does anyone know how/where can you modify the thermal throttling values? After playing a game or two, FPS drops like crazy and the phone is really hot. Mind you it gets really hot if I'm charging it with the stock charger from say 18 % or if i'm playing a game for 5 minutes. Sensors say that it's 45 C, i forgot to take measurements with a thermometer.
[Android General] miljenko:
I have prepared V2 of the stock mod firmware with following changes:

- Based on latest official update 20150314-135111

-De-odexed and zip-aligned apps

-AOSP feel

-Changed navigation bar to looks like Lollipop one

-Width of navigation bar reduced (easier use)

-Signal icon reduced and changed into white

-Lock screen clock reduced size

-Google Now launcher

-Killed stock theme service and left wallpaper chooser

-Many other things that I don't remember

DOWNLOAD LINK

Suggestions are welcome. I have not tried too much to theme it like Lollipop since we will receive it soon anyway.
[Android General] 1rnst:
I see it is mentioned that the updated official firmware is only chinese and english language, what is the point ?

If the phone is shipped with multi language, it will be lost if doing update.

I am about to order one of this phone, it looks good. But I like to wait a bit to see what problems can

be found.
[Android General] miljenko:
All languages are included into this firmware. I did not have this problem with languages after update.

Phone is good, I have not found any downsides till now.
[Android General] Calugarar:
There's an issue with unlocking the screen after enabling root, exposed and then rebooting. It happened with V1 of the firmware as well.

Didn't gave it too much thought but it happened again now with V2 as well. It's like it doesn't recognize touch input. A quick reboot fixed that. I just thought you should know. :)

So far the phone was in general snappy, there was a hick-up every once in a while but nothing too bothering. Like the general look of it and the boot animation. Nice work! :good:

---------- Post added at 10:26 PM ---------- Previous post was at 10:18 PM ----------

Where did you see that the updated official firmware is chinese and english only?

My only gripe is the overheating easily and battery life, could be a bit better. But the latter will be "fixed" with the release of the optional 3000 mAh battery.
[Android General] miljenko:
Thank you for a bug report. Could you please explain me what kind of problem with the lock screen you have, so I can try to fix it for the future.
[Android General] Calugarar:
Hey, no problem.

Well it usually happens after first reboot right after i flashed the ROM (before flashing the ROM i do a factory reset just to be sure, came from stock ROM with 0314 update applied).

So i flash the ROM, boot turn on wifi, sing in to google account, turn on Root and then install Xposed framework, it asks me to reboot so i do. Then after it's rebooted it shows the screen locked and when i swipe to unlock it, it doesn't take my touch inputs, even if i try to drag down the status bar.

So then I press and hold the power button ant tap on reboot (weirdly enough that touch even it detects), it reboots and it works fine (unlocks the screen without a problem.).

If you want i could try to record it a LogCat through ADB, if that will help.
[Android General] miljenko:
I just re-installed firmware, tried to replicate your steps and didn't have any unlock problems.
[Android General] 1rnst:
In post#65, say only chineese and english.

I have compared this phone with Kingzone N3 that has NFC. It has 2GB memory, perhaps this will be a better choice ?
[Android General] miljenko:
That was different firmware.

Regarding phone choice, once I have bought phone with bad firmware support and that will not happen in the future. Iocean have very good reputation for durable hardware and good software support.

This days customer support is most important thing and iocean confirmed my word by replying in few hours. For the people having problem applibg update they created full firmware flash in only one day.

This are reasons for me choosing iOcean as company.

Miljenko
[Android General] Calugarar:
Apparently it has something to do with the lockscreen widgets. If the option "maximise widgets" is ticked, then I can't unlock the screen. Couldn't record that as I have to reboot the phone in order to unlock it again. But I was able to reenact that behaviour by simply swiping up on that arrow at the bottom of the screen.

There you have the screen recording.

http://s.go.ro/lxxtz

Update:

Apparently it does while I swipe up from the home screen as well.

http://s.go.ro/qzs05
[Android General] Calugarar:
Welp so much for first production batch quality. Apparently the glue that keeps the screen on the device is failing. Maybe it's caused by the heat generated by the phone.

There's a noticeable flex and sound (the sticking and the releasing kind of sound) when lightly pressing the screen near the volume + power buttons, which sometimes causes the phone to go in a boot-loop (probably it activates the buttons when there's pressure on that area).

And no, I didn't drop the phone or anything, most of the time i kept it with the included plastic case on, which by the way fixes the boot-loop issues when it's on. I contacted iOCEAN on Facebook to see if they have a service in Europe as I need this fixed ASAP.
[Android General] miljenko:
Unfortunately it problem with Bottom quick action addon. In next version I will try to disable it.
[Android General] mesang:
I'm having issues with the G sensor. If you are holding the phone completely still while looking at a 360' spherical video it keeps sliding slowly down to the left side. The same with VR games. Seems like a sensor problem. Is there any way to calibrate these?
[Android General] Calugarar:
Try with MTK Engineering, Mobile Uncle tools doesn't seem to work.

Start the app, then go:

MTK Settings -> Hardware Testing -> (scroll down to) Sensor -> Sensor Calibration. Put it on a flat stable surface, calibrate, test it out and post results. :)
[Android General] mesang:
Thanks, will try!
[Android General] Calugarar:
No problem!

By the way, if you don't want to install the app for what ever reason, you could just go to your dialer and type in:

*#*#3646633#*#*

And you'll be in engineering mode. ;)

---------- Post added at 05:42 PM ---------- Previous post was at 05:34 PM ----------

Good to know! I think that the random reboots that I have been experiencing were caused by Xposed. I disabled it since this morning and haven't experienced a single reboot. Will give it some more time before i can definitely say it was caused by it. If it was, i'll try and workout which module did cause it and will report back. :)
[Android General] Calugarar:
Well more than a week has passed and i think i found the Xposed module that was causing the bootloops, after i disabled the Amplify module the phone seems stable which is great.

As a further update to my issue with the screen getting unstuck from the frame, i have contacted iOCEAN support by email and social media but when it came to reaching an understanding on how i should return the unit to them for further inspection/servicing/replacement, they broke off contact with me .Apparently they don't care about customers that are unlucky to have physical issues with the phone. In addition to the screen slowly coming off i noticed that there's a squeak near the power button.

So warranty wise iOCEAN isn't as good as i though it would of been.

Those that are curious to see about the issue what i was talking about you can see a video of it here: http://s.go.ro/kqfyr

Guess that i'll have to fix it myself, does anyone have any suggestions on what kind of glue i should use once i took it apart?
[Android General] Sefy:
I hope you guys can help, a friend of mine just purchased this phone and received it this past thursday.

Everything was working great, no complaints!

Then we noticed there was an update in the "Wireless Update" of 75mb, we applied it.

Right after it finished, the screen started flickering like crazy and seems that it's resolution is wrong.

The top bar is appearing also on the bottom.

I've managed to install TWRP and downloading the official Firmware again to hopefully solve it.

But i'm curious if anyone has had this issue? this is happening even in Bootloader and TWRP!

EDIT: After using the FlashTool to restore original 0314 firmware, everything works normal again

But performing the same 0317 update, makes the screen flicker again. So i've restored 0314 to

make the phone useable. Has anyone else experienced this issue?
[Android General] Calugarar:
Nope, just tried the OTA and it said it has the latest SW. Which is 0314 from mjlenco.

Maybe capture the update and post it here? Otherwise I for one can't do it seeing that i didn't receive an OTA.
[Android General] Sefy:
The Wireless Update says current: M6752 20150129-172129

Then it tells me that i need to update and there's that 75mb download

How do i capture the update?
[Android General] Calugarar:
When you download it, it should make a folder that's named update or something similar on your phones storage. Just look at the folders that are there before you download it and after you downloaded.

Did you flash the image from the Iocean.cc support page? Because the date on yours looks like it's the one my phone came with by default.

Capture the file if you'll need it in the future and then flash the image with the update from the Iocean.cc site.

If you need the tools to flash and whatnot, you can find them in a few posts back.
[Android General] Sefy:
Yes, that's the Flash i took (M6752 0314 Version Android 4.4.4 ) then it tells me there's a 0317 update.

Strangely though that right now it's now saying there's an update, so once it does, i'll save it and upload someplace.
[Android General] Sefy:
Things have gone from bad to worse, now i'm unable to place or receive any calls! :crying:

I've tried this flash blob:https://mega.co.nz/ee32b3b1-f9b5-4018-9684-debeff4ddc2e

and not only i can't make any calls, the screen is in having a seizure!

Only if I flash the previous version then the screen looks normal, but on either ROM (even with full Flash and Erase!) i can no longer place calls but it DOES have 3G/4G internet access and I DO see the network bars connected and i've tried both SIM sockets.

Same SIM works on M7 phone, so it's not the SIM card.

Here is the video showing the issue: https://vid.me/SjQa
[Android General] Calugarar:
This sounds so strange. If it's a hardware issue I doubt that iOCEAN will fix it for you as they completely ignored me with my screen issue.

Where did you besought the phone from? These things do seem odd.
[Android General] Sefy:
This phone was purchased on AliExpress on the big sale they had last month.

The thing is, when the phone was received, everything was working perfect!

It's only when it got updated (officially!) to that firmware that exists on their website.

That's when things went kaput and i saw that screen issue you are seeing in the video :(
[Android General] Calugarar:
Did you contact Iocean about this?
[Android General] Sefy:
I sent an email but did not get a reply, assuming due to holiday
[Android General] Calugarar:
Post in on Facebook or Twitter on public or maybe public image will be a pressure to get your fixed.
[Android General] miljenko:
In system/about check your IMEI, it might be lost.
