Can someone explain me how to flash G930U to G930T?

I have the following device info:

Model number : SM-G930T

Android version : 7.0

Android security patch level : May 1, 2017

Baseband version : G930TUVS4BQE1

Kernel version : 3.18.31-10376601

Build number : NRD90M.G930TUVS4BQE1

I mainly want to do this because i have a very poor battery life. In approximately 2 hours of doing nothing, i lose up to 20% percents of battery. I have tried everything : wipe cache, factory reset, i have package disabler pro, location is not always activated. It all started with the second release of Android 7 beta. On the first beta release battery life was awesome, much better than on Android 6.

If i flash to G930U, what will be the advantages? Will I have better battery life? Thanks.

Whats you need to do is to install sp flash tool on your pc and the stock rom for your mmx unite 2 lollipop .then install sp flash tool and and execute the program ...then there will be a command 'Scatter file' ....click on that and open that in fhe Firmware folder of your Stock Rom ....the connect ur device using usb cable and then click download in the sp flash tool......after completing that disconnect ur devices and reboot it....
[Micromax A106 Unite 2] Abhinay Pandey:
Wrong Choice!

Flashify and Twrp are both bad for Unite 2!

You would have flashed the Philz Recovery with SP FLash tool and then flashed the TWRP recovery using it!

Now Still you can do the same

Just google philz recovery and you will get a detailed answer there!:o

Your phone appears to have gone into a bootloop.

Here is what you can do as you can't get into the system and reboot into recovery mode. Just confirm if you are doing it the correct way.

If the above steps failed, proceed down below.

Things you will need:

1) USB to PC connecting cable

2) A PC where you can download one of the tools to recover (MTKDroid/SpFlash along with the device specific Scatter file)

3) USB drivers installed on your PC to connect with your phone

4) Patience to read references and follow the steps to flash recovery using Tool

[MTCD  Android Head Units Q&A] wskelly:
Must be rooted.

Install kernel adiutor.

Start Kernel Adiutor. You'll be met immediately with four graphs showing the load on all four cores.

Select "CPU"

What you will notice by looking at the CPU frequency graphs, is that the head unit spends most of it's time at a low clock frequency, typically 800MHz or so.

Select "governor". The default setting is probably "interactive". This is not a phone. Any governor setting that favors low energy consumption is not appropriate for an automotive head unit. The kernel governor's job is to throttle the clock speed up or down to meet demand. So when the device isn't doing anything, it can run at a lower speed and conserve battery.

Scroll down to and select "performance". This will lock the CPU at 1.6GHz.

Use the "apply on boot" switch to make kernel adiutor start up and apply the setting at every boot.

You will notice dramatically improved responsiveness (immediately) overall.

This should also work with MTCB units or other (non-Joying) units. You must be rooted.

If someone can provide screenshots of the CPU frequency graphs (before/after) I will add them. I am too lazy to run mine in the old state just for getting a picture of before/after, but in a couple of days I will try to add some pictures.

I don't know if the chip will eventually burn up. If it was designed properly, it won't. The Rockchip is used in millions of tablets and other devices, I suspect it is robust by now. It is also advertised on Joying's website as a 1.6GHz quad core, so why is it running at 800 MHz or lower all the time?

There may be a tradeoff, perhaps using ondemand? Would be worth playing around with the other governors and settings to find a way to get max speed only when it is needed. But then again, there may not be any reason to mess with this at all.

This is *not* overclocking and the kernel governor is not a secret.

The performance governor will force the processor to run at its maximum advertised speed. I have been running mine this way for >1 week now with no ill effects.

Following these instructions is at your own risk, like almost everything on XDA.

[MENTION=4263226]da_anton[/MENTION]
[MTCD  Android Head Units Q&A] da_anton:
There is already a thread here on xda discussing this. Actually that thread started at that time discussing if some sort of overclocking is possible. I'm not so sure if setting the soc to performance Governor and therefore always 1,6 GHz is a good idea. I agree with you that it definitely is an improvement and the unit feels more responsive. But as there is no heat spreader on the soc and the cooling is not very good where the unit is usually placed I'm not so sure if this does not reduce the lifetime or even kills it as someone said that the Rk3188 has no temp management.

I would instead recommend to try tuning the interactive Governor settings instead. The default settings almost never scales up to 1,6 ghz as you found out. But if you set the following two tunables with kernel audiutor the soc will scale up to max as soon as 60 percent load occurs on a core. This at least improved my unit while still keeping the advantages of dynamic frequency scaling. Here are the two variables

/sys/devices/system/cpu/cpufreq/interactive/go_hispeed_load 60

/sys/devices/system/cpu/cpufreq/interactive/hispeed_freq 1608000

I already did some programming to set this variables as early as possible in the boot process without the need of kernel audiutor. But so far it is only active on my unit.

[MTCD  Android Head Units Q&A] gunmoule:
Someone around here was discussing possible heat problems on these rockchip units, being why the manufacturer chooses to set the CPU governor this way.

I don't know if this tweak is really advisable unless you add hardware mod like passive heatsink or fan to the chip. I couldn't find any temperature data or sensors from the chip.
[MTCD  Android Head Units Q&A] wskelly:
Thanks for the info, didn't know about the other thread.

I wonder if... They just forgot? ;) Has anyone actually experienced a thermal. failure? Is there a data sheet for this thing? The Rockchip is by nature a low power device and they made a design decision not to include thermal management (or even temperature measurement?) ... To me it all points to "should be fine" but your solution is definitely more conservative/safer.

I have an infrared temp gun, but I need to pull apart the dash again, disassemble the unit, remove the DVD transport, and then drive around like that taking measurements... Probably not going to happen.

I did see some photos where a guy added some heatsinks...? On the Joying website maybe?
[MTCD  Android Head Units Q&A] da_anton:
I don't know about the Joying website. But ptclabs and I did this and we posted it here: http://xdaforums.com/showpost.php?p=68899885&postcount=22

As I have a heatsink on my SoC I don't mind having it at 1,6Ghz most of the time. But publishing this for everybody as part of a public ROM is maybe not a good idea without being able to measure the CPU temp. That RT3188 is really a cheap piece of electronics. ;)

I don't think you have to drive around to measure this. I guess you could just use a generic 12V power supply and power the unit on your desk. The correct wiring should be written on the unit. Then you can just use any CPU burn app from the Play Store and measure the temp of the SoC with your infrared thermometer. Would definitely be a nice project! :)

So been working to make this ROM a bit faster. I changed the boot animations to the stock Audi one and shaved 5 seconds off boot. Then I went into developer options and turned off the animations. If you want the transition 0.5x works great too. Next I deleted all the launchers I wasn't using since they have a startup at boot. Now I got a little more in depth. I installed Kernal Adiutor (ROOT) and watched the CPU. I ran a bunch of programs in the background, starting maps, changing menus and noticed the CPU rarely went above 816 Mhz. So I went to adjust the Governor. The performance CPU Governor made everything snappy but running the 1.6 Ghz constantly can't be good for the CPU. I went back to Interactive and adjusted hispeed_freq to the maximum 1.6Ghz and go_hispeed_load to 80% (was originally 96% so 1.6 Ghz would never come on) Finally opening apps would trigger the 1.6 Ghz but it would still go down to the minimum even with Here weGo Maps. I didn't want to mess with the other settings cause I don't quite understand it well. If someone here know how to tweak this CPU more please let me know!!

DO NOT LOCK YOUR CPU ON MAX SPEED. YOU WILL BURN YOUR STEREO UP. Read my research above to speed up your system, without burning up the CPU. Been running those setting for a month.

Talking about the person who started this thread WSKELLY, unless you two are the same person. I find it hard to believe, out of the 1000's of cpu governor apps, the same one I listed had been chosen.
[MTCD  Android Head Units Q&A] marchnz:
Can you be sure? I missed your post too as helpful as it is.
[MTCD  Android Head Units Q&A] shawndak:
Only person that can be sure is the thread starter. Of course we both could have stumbled upon the same idea to speed up a laggy system with a background of CPU governor work. We would then set out to pick the exact same program to set the governor. Just seems odd to me.

Anyways hope my governor adjustments suite y'all. Would highly recommend not running the CPU at max capacity especially when cars can easily get to 150 + in the summer. My xtrons unit has a fan and very large heat sink and I'm still nervous about it.
[MTCD  Android Head Units Q&A] Mighty_X:
Actually I did exactly that about 2 weeks before this thread was created... It's the most logical thing to do for a noob...go into playstore, type kernel and this app is first result. Go in the app, scroll the options and obviously "performance" sounds promising... Very ordinary I think

Reminds me I need to add on a heatsink to the RK3188 in my unit. It couldn't hurt.

[MTCD  Android Head Units Q&A] avionaru:
I did the Aiuditor thing from the other thread cited here, a couple of weeks ago. The unit has visible improvements in speed. However, it froze every 10 minutes or so, so there's definitely a heating issue. Now the outside temperatures have dropped here to around 5-8C, so I think I'll give it another shot, just for curiosity.

The next step is to find a heatsink somewhere (shop or my old hardware parts) and mount it as [MENTION=6005745]ptclabs[/MENTION] explained.

This is definitely another marketing sh*t from Chinese manufacturers, the 1.6 clock speed is almost never achievable under their settings/hardware design.

Lol!

Sorry you feel like "your info" was stolen. I've been using this app for years. Are there others? And I didn't see your thread in the MTCB forum, why would I?

I'm running at max and have not had a freeze yet. Are you running a stock ROM or modified or...? MTCD? Do you use Xposed
[MTCD  Android Head Units Q&A] avionaru:
I think at that time I was on Malaysk 6.0, MTCD HA, no Xposed or anything fancy. I just wanted my unit and Maps to start as fast as possible.

Now I am on Malaysk 7.x (latest), latest MCU, I will try again.

I never had freezes until I set up the governor to performance, and the issues dissapeared after I disabled it. Most likely I need to tweak the settings a bit.
[MTCD  Android Head Units Q&A] marchnz:
Excellent post, all comments while helpful are anecdotes. From manufacturer data max operating free air (no heatsink) is a quite high 125degC. This suggests to me that another component thermal profile maybe impacting performance but again no hard data. Getting the unit hot with say a hairdryer and cooling various components with freeze spray while the unit is slowing down might be a suitable test to identify if overheating is a factor.
[MTCD  Android Head Units Q&A] da_anton:
I think we can answer that question very easy:

Kernel Audiutor - governor to performance

https://play.google.com/store/apps/details?id=com.into.stability

If the unit fails/reboots/produces popcorn or whatever nonsense: we should not set it to max. Otherwise tuning the interactive governor to scale more aggressively should be ok for everyone.
[MTCD  Android Head Units Q&A] marchnz:
How does that help determine the component which might benefit from cooling in order to provide best possible performance as some posts suggest overheating as an issue.
[MTCD  Android Head Units Q&A] avionaru:
Man, you are correct in theory, but for this unit/purpose most of us care about the practical thing, not the perfect scientific way to demonstrate stuff. There is no constructive point in keeping this "the manufacturer says it's ok up to XXX degrees, so your empirical evidence does not stand", without an effective solution proposal to solve it. The hair dryer/air cooler thing is pretty hard to do with perfect lab conditions to validate results, but if you already have a setup that can do that, it would be a nice thing to try. Otherwise it's just a lack of focus.

While I am more inclined to the overheating theory (considering that I got the exact same behavior with Aiuditor on two Samsung phones that had sensors and they were overheating), it may be a software glitch also, but I have to do more attempts to pinpoint it (maybe the kernel is acting up).

After I stabilize the ROM, I'll do some more combinations of settings.
