I do remember that MCU upgrade screen every time the unit boots, I think it was an unresolved bug that I forgot about. I'll add that to my to do list. Shouldn't be too hard to find in the code and patch.
[FYT Android Head Units] gtxaspec:
The bricked unit, do you still get the Signature error?
[FYT Android Head Units] doctorman:
for the Bricked unit I still get this page and never goes beyond
[FYT Android Head Units] gtxaspec:
Are you able to boot into Android?
[FYT Android Head Units] doctorman:
OKay I can confirm that the latest version (Jan 2018) of Original Joying ROM at this date for MCU 9-5 has a bug...

Use an older version of the MCU 9 ROM

fixed my MCU error using Novermeber 2017 ROM from Joying, I am sure I can upgrade to your ROM without any issue.

---------- Post added at 02:34 PM ---------- Previous post was at 02:30 PM ----------

no

when I turn it on, it keeps rebooting and sometimes I get the 1 st Joying screen

when I plug in the USB or SD card with ROM on it after 3 reboots it recognizes the ROM and tries to install it

and that is the writing I get on the screen and it stops there
[FYT Android Head Units] gtxaspec:
The incorrect recovery is installed, I can get you a rom to fix it.
[FYT Android Head Units] doctorman:
YOU ARE THE BEST!

How long do you think it will take to get that ROM...

I have it all open .. :D
[FYT Android Head Units] sanangel:
Something new? (Just ask, I do not mean to hurry, I do not want to be rude or misunderstood)
[FYT Android Head Units] gtxaspec:
http://mirrors.gtxlabs.com/joying/1_Firmware/lbdroid/testkeys_to_stock.zip

Install that, then install the stock ROM, afterwards.
[FYT Android Head Units] doctorman:
There were 2 files in that ROM.

5009_60.zip

Allapp.pkg

I put that in the SD card and let the unit run for 10 min so it goes through few reboot cycles

I did not see anything happen on the screen

I assumed maybe it does recovery installation silently

then I turned off the unit and attached the Joying ROM MCU 9.20 to the USB and let it run through few reboot cycles as before

after 3 reboots the device picked up the ROM and started installing and stopped again with the same exact error "Signature verification failed"

so bottom line I dont thing your ROM actually installed
[FYT Android Head Units] gtxaspec:
Make sure you have the sqlsofia file from the stock rom in the SD card, then try again.
[FYT Android Head Units] doctorman:
ok so 3 files are on the SD

SQLSOFIA

5009_60.zip

Allapp.pkg

Your ROM installed!

Android is booting but it did not go anywhere after 10 -15 min. I just connected the USB with Joying original ROM and it went through the installation of the Joying ROM right in the middle of Android Boot.

Seams like this is fixed

Not sure how you got this done but thank you!

[MENTION=2366275]doctorman[/MENTION]: I noticed by your pictures that you have a 6021 without active cooling... You might want to look into that soon, as these things get hot !! It would help with performance, and with longevity too.
[FYT Android Head Units] doctorman:
they do get hot ...

I will consider it, but I might upgrade to Octacore with 4GB Ram

P.S. If anyone needs Joying parts or Double Din or singDin metal box I might be able to help you out, I am clearing my stock

---------- Post added at 08:24 PM ---------- Previous post was at 07:58 PM ----------

Just a note... I should have installed the Joying 5.25 MCU ROM after this... I got the annoying MCU Yellow bar on this one now and it did not go away by installing the November 2017 9.20 ROM again.

did a data reset and installing the 5.25 ROM now and that took care of the Yellow MCU Bar

it bugs me what makes this MCU Yellow bar to come about

Anyway I am all up and running!
[FYT Android Head Units] Redbullssg:
I'm very glad I did mine... I was running nothing below 60°c, and mostly more, constanty before... Now I never get to 50°c and most of the time under 40°c.... I was driving with my air on yesterday and it got down to 24°c while running my music app, Viper and other apps in the background, that's with the custom tweek locked [MENTION=1348102]1200[/MENTION]. I've never seen it that low before... It was well worth the time, and didn't cost me a thing, as I had all the parts laying around. Well, I did go buy some thermal paste.. Shwew that set me back.
[FYT Android Head Units] D3LTA:
I have created a Fast Joying Sofia repository as it seems hard for people to find working stock roms and too keep al usefull **** together...

Please give me some suggestions what you guys miss right now, so i can add it.

Thank you
[FYT Android Head Units] wanb1i:
I did mine as well, but I'm not sure if the temperature gauge is displaying correctly. It displays 60C at startup and then runs up to 70-76C. I was using CPU Monitor and it would display 35C at startup and run 45-55C. But it couldn't survive when the HU would sleep. So now Im not sure what the temperature is...

Anyone have any ideas?

Also, has anyone bought the Oreo Upgrade yet? I'd love to have an idea how it performs before I buy it. I'm very concerned about the firmware stability, knowing there's no GTXROM for it.
[FYT Android Head Units] myxcon:
Awesome. For which MCU is the stock rom provided in the mirror?
[FYT Android Head Units] Redbullssg:
I installed Resource Monitor Pro, and use the one the Xposed, and they both read pretty close to the same for me.

Do you have a fan installed as well? With no air conditioning on, mine still stays low. Doesn't get over 60c on a hot day.
[FYT Android Head Units] wanb1i:
Yup, fan and dual 40mm heat sinks. It seemed to really keep it cool when I was monitoring it with CPU Monitor. But the temps went way up using the tool in xposed. I'm going to try the app you mentioned and compare them.

I'm also considering the Octa-Core/Oreo Core upgrade. I'm afraid I may have waited to long to add the active cooling and toasted my Sofia.:eek:
[FYT Android Head Units] gtxaspec:
I've run the Sofia over 100c (yes, celcius, overclocking)...for extended periods...still alive, you have some hope lol.
[FYT Android Head Units] Redbullssg:
Lol, maybe it's because I use my air too much. I got in the car the other day, was well over 40c in the car when I got in after work. When first started it, the temp read 62c and then slowly went down... Im using the over clock on your custom app. How on earth does it reach 100c

I'm a standard guy, not metric. I literally had to go convert it to figure out how hot that really is, lmao. That's hot!
[FYT Android Head Units] gtxaspec:
With no active cooling in the unit on a hot summer day.
[FYT Android Head Units] pilotbob3:
Hey wanb1,

I just installed my Octacore board replacement. If you'd like my Sofia for an agreeable price, PM me. I have a Sofia board with mounted heatsink/fan ready to go.
[FYT Android Head Units] Astur_Torque:
I have a lot of bugs with 9 alpha 4...

For older Sofia MCU, can we overclock to 1200 Mhz?
[FYT Android Head Units] edit:
Can you overclock it? How much did you manage to push the 5009? 1.2Ghz?
[FYT Android Head Units] D3LTA:

[FYT Android Head Units] Redbullssg:
The GTX Custom mod locks it at 1.2ghz.... Mine always is always at 1.2ghz, no throttle down...

---------- Post added at 03:52 PM ---------- Previous post was at 03:49 PM ----------

But it's so easy, why not? I never over clocked mine before the active cooling was installed, sure if it was, I mean, that is a huge difference.... I'll have to see what mine reaches to without the air on, on a hot summer day and compare.
[FYT Android Head Units] wanb1i:
I know this isn't the place to ask this, but I searched for a thread on the Octacore upgrade and couldn't find one, so here goes.

How do you like the upgrade? Was it worth the investment? Does it run smoothly with Joying FW?

I'm thinking of getting it just to get Live Wallpaper back.

GTX, has anyone been able to get Live Wallpaper to work on this ROM? If so, can you please point me in the right direction?

The Octacore and added memory has to be faster and less laggy?

BTW, I'm not really interested in your Sofia, I'd rather spend a little more and get the Octacore, lol. :cool:
[FYT Android Head Units] Ford_OutLaw:
Does TWRP function normal or is it limited? For example if I wanted to flash a zip would it work or just bork everything? Or if I wanted to do a normal backup and/or restore?
[FYT Android Head Units] pilotbob3:
Hey wanb1i, I really like the upgrade. Certainly worth the money for me. I'll comment on the other thread as not to mess up gtx's great work and thread. Thanks to him for all the work, but moving on from the Sofia...

Are you sure your is 5009 instead of the new one? Maybe this rom wears an old kernel or something

I'm using the V9a4... As far as I know, everything tells me it's the 5009... Shiny aluminum flat heat plate. Said 5009 on the sticker, and say it in my info.

I'll look at another monitor to see what it says.. Maybe it's defaulting to what it's locked to, and not the actual hz it running.

OK not sure what happened. I installed v9a4 (clean install) everything went fine during the install and it booted fine. I went into Viper to install driver and after the reboot I am stuck. The Leds will cycle purple 3 times then stay solid purple and nothing ever shows on the screen. I have tried the Stock joying firmware on a usb and same boot cycle/color sequence occurs.
[FYT Android Head Units] Redbullssg:
I disconnected power from mine yesterday and when turned on, did the same thing (purple lights, three times, black screenl. I was worried as it never did that before. But, after the third time, it sat there for a while, but then booted back up... I don't know what that was about. Never did that before.

I have mine on my desk right now so I will let it sit with the solid purple and blank screen and see if anything happens in maybe 20 mins?
[FYT Android Head Units] Redbullssg:
It wasn't 20min, but it did take a little time.. I may have even touched the power button after a bit. It did reset the stock settings, like the beep and the EQ and such.

---------- Post added at 07:05 PM ---------- Previous post was at 07:03 PM ----------

That looks identical to my heat sink and fan., I thought for a second, it was my pictures, lol. That set up worked very well... What did you use for thermal trans?
[FYT Android Head Units] Ford_OutLaw:
Thanks, I have hit the reset multiple times. I will give it some time and see if it does anything.
[FYT Android Head Units] Astur_Torque:
As you can see the maximum is 1040 mhz :(

[FYT Android Head Units] Ford_OutLaw:
Well 35 mins and still a blank screen and solid purple leds. I will leave it running and check back later and see if anything happens
[FYT Android Head Units] D3LTA:
Thermal trans? You mean thermal compound or thermal switch??

Anyway used artic silver 5 compound on heatsink and amp and used gasket kit for fixing the headsink with 4 small dots in the corners too keep it firmly in place..

Used ground and amp-cont from iso connector for power.

Used a 12v to 5v 2x USB for the 5 volt so I have one spare 5v 3A usb out of back for charging, and it's working great lowered temps by 30 to 45 °c on load..

I'm happy with that :)
[FYT Android Head Units] surfer63:
There is no overclocking on this units.

The 5009 which contains a slightly older model of the Sofia has a max frequency of 1.040 GHz

The 6021, which contains a newer type of Sofia has a max frequency of 1.2GHz.

You can lock the frequency at its max. frequency, which [MENTION=520205]gtxaspec[/MENTION] is doing, but you can't overclock it.
[FYT Android Head Units] Ford_OutLaw:
Still solid purple/pinkish lights and a blank screen 3 hours later. Just did a reboot and the same thing no boot logo or anything just black
[FYT Android Head Units] Redbullssg:
Mine didn't take that long....
[FYT Android Head Units] Redbullssg:
Not saying you're wrong, I just don't understand why both monitors say 1.200ghz, both the JET and the other. Is this a glitch?
[FYT Android Head Units] Ford_OutLaw:
Last update for the night... Still stuck on the pink led cycle with a blank screen. Things that I have tried, test keys, stock joying firmware, gtx v9a3 and v9a4. All have been tried on multiple USB drives and microsd. After searching in another thread I did see [MENTION=520205]gtxaspec[/MENTION] mention to leave the unit off for a day for the nvram to clear.
[FYT Android Head Units] wanb1i:
That's great! What other thread? Got a link? I couldn't find one when I searched for It the other day...
[FYT Android Head Units] surfer63:
Do you have a 5009 or a 6021 unit? That makes the difference.

So if you have a 6021 you can run 1.2GHz.
[FYT Android Head Units] Redbullssg:
Shiny aluminum flat heat sink, sticker on it said 5009. System Info also say 5009.
[FYT Android Head Units] surfer63:
The flat shiny heatsink is indeed 5009.

The system info always says 5009, also on a 6021. You can't trust that one.
[FYT Android Head Units] Redbullssg:
Then it showing that I'm running at 1200ghz is wrong?
[FYT Android Head Units] skezza:
I can't believe anyone wants to overclock these Sofia units? Utterly bat **** crazy. If anything you should be underclocking them :D
[FYT Android Head Units] surfer63:
No, the app simply reads the current frequency. It is just weird that the 5009 runs at 1200 MHz. As said: There are 2 Sofia chips: one running at 1040 MHz and one running at 1200 MHz. It almost seems they put "the wrong chip" in your 5009.
[FYT Android Head Units] Redbullssg:
I was going to suggest that, but didn't want to be called crazy, lol. I wonder if there is any other way to tell... And if it is the 6021, would it have somehow installed wrong things. And would the allow me to upgrade to the new board

---------- Post added at 06:59 PM ---------- Previous post was at 06:58 PM ----------

Why not, people been doing it for some time now without issues. Even the guys without active cooling.
[FYT Android Head Units] Ford_OutLaw:
Under my 6021 (right under where the WIFI is soldered) my board says FYT6021/6022 I wonder if yours says the same and if the 5009 crowd has the same printed
[FYT Android Head Units] skezza:
The Sofia chip runs warm, heck it runs hot. They probably run hot enough to provide central heating for the coldest parts of Iceland. Intel have always had issues with their chips running hot. They once closed down an entire division because after several years of trying to make their mobile chipsets run cooler, they simply gave up..... and you say people have been doing it without issues but I'm afraid to say that's bollocks. Joying units have a long and decorated history of cooking themselves.

Use your brain for a second.... if they didn't have form for burning up, people wouldn't add active cooling in the first place. Duh. Instead of overclocking them and crying when they fry up, look into other ways of making them run faster and smoother. Overclocking is a lazy way of fixing a problem that isn't there..... well, until you make it.
[FYT Android Head Units] Redbullssg:
I'd say it's running pretty cool jamming my tunes, with Waze running, Viper running... scoff all you want, I haven't heard of a notorious amount of Joying users complaining about their head burning up... Do what you want, I'll do what I do.... View attachment 4524273
[FYT Android Head Units] skezza:
I'm not 'scoffing'. If it runs perfectly, why the hell are you overclocking it? For leetness? For the lulz? For reasons?

Yeah, no **** they don't burn up..... except literally everybody who owns one seems to think they run far too hot.

The Sofia isn't a bad chip. It's more powerful than many of the ARM equivalents and still considered more powerful than the A53's etc, but it runs hotter and why the heck you'd want to put your device at risk, having spent good money on it..... when let's be honest, what are you going to gain? Another 20 in Antutu? It's not like you're playing games on it, and if you are, please focus on the road eh?

I am trying to revert back to the stock Joying ROM , i have restored stock recovery from the custom app , but when i plug my USB it dose not show the upgrade dialog like it used to.

A bigger problem is i activated the performance mode on my stock unit , now it is stuck in a boot loop because its running too hot , how can i revert it back to normal mode ?

When ever i get or make a phone call the other end cant hear me , all what they hear is loud static noise , mic is working and tested with ''ok google'' , and idea how to solve this ?
[FYT Android Head Units] gtxaspec:
Download and enable xsofiatweaker. That fixes the static.
[FYT Android Head Units] Redbullssg:
Not playing games on it, and if I were, it would be on idle time. I watch video, surf the internet, listen to music, and almost always have Waze running often when listening to my music, and if you have Viper, you need to overclock for all to work flawless, no skipping, etc....

The heat sink and fan lowered the Temps significantly, and was well worth it, even if I didn't overclock.... There is NO issue with overclocking it, and I have not had a single issue with it since I did. It runs nice and cool, and can load this thing down without worry...

As far as the many over heating, you're speaking about phones, and yeah, I can understand that.... There is no cooling what so ever. In these heads, it has a heat sink, and airspace to cool it... Like I said, I haven't heard about a bunch of Joyings having huge issues with overheating... Just isn't relevant to this. Especially if you add active cooling...

Sorry [MENTION=520205]gtxaspec[/MENTION] for soo much off topic...

You will need to go through the stock backup recovery in settings AFTER restoring stock recovery and confirming to revert back. It won't do it automatically like it did before.

What rom were you on before you flashed? The behavior you describe sounds like the old bootloader before the December ROM. Next time you can boot in, re, flash the stock recovery. Report back.

The newest joying firmware I think it was 1-18-2018?? it was the first thing I did when a received the unit a week ago.

Edit: I ran v9a3 for a few days with no issues. First boot with v9a4 was fine but after I installed viper drivers and it asked to reboot.... I have regretted that "sure" for the past day and a half
[FYT Android Head Units] gtxaspec:
Restore stock, then re install the latest STOCK firmware, then try custom rom again
[FYT Android Head Units] Ford_OutLaw:
Will do if I can ever get it out of this pink cycle. I have no idea how it booted earlier. Like I said before good news its all there (I was starting to get worried that I corrupted something)
[FYT Android Head Units] surfer63:
Yes, the Sofia runs hot, but the PX5 in my unit runs even hotter. I have both units: a Sofia 6021 and a PX5 6026 (both FYT models). So please don't start this "heat issues" with Intel. The PX5 (A53) is also heavily used in (cheap) video streaming boxes (as alternatives for apple TV and Google Chromecast and the like). All these units come without cooling. Almost all users wanting to view 4K on hevc (x265) encoding need to add a cooling fan and heatsink as to not "melt" the PX5. It is not an Intel issue only. You are right though: Joyings can end up cooking themselves, but that is the same for PX5s as well as Sofias (read "my" PX5 review thread and see the Youtube video where I show how extremely hot the uncooled PX5 chip runs: >105 C)

With regards to speed/performance: Whether the Intel Sofia or Rockchip 8-core A53 model (note that there are quite a lot of A53 versions. Not just one A53 and not just Rockchip) "theoretically" runs faster or not is not relevant: measuring is the only real "fact". I personally experience (and so does [MENTION=1157125]treel[/MENTION], formulating it very carefully) that the PX5 is faster in everyday use. I also ran benchmarks on both units, and ran comparisons with the same programs (stopwatch and fps measurements) that I daily use, "proving" that the PX5 is (slightly) faster, both CPU as well as GPU wise (somewhere in "my" PX5 review thread). I guess this is maybe partly due to software optimization. Unfortunately I can't find the selling figures back, but >98% of all android devices are ARM based. The other <2% is Intel and the almost dead MIPS. I guess the code is so optimized for ARM that even (theoretically) slower ARM chips give a faster/better user experience. Of course this explanation is all guessing, but my personal user experience is indeed that the PX5 is slightly faster, even when throttling down. Again: this is not a general comparison, just a comparison of the Sofia and PX5 as used in the Joying units.

Finally: There is no overclocking on these Sofia chips. It is either forcing the Governor to run the chip/cores constantly at full speed, or let the Governor decide by itself on necessary speed/frequency by setting a Performance, Conservative or Energy profile. That is what the GTX Rom does: running the CPU cores constantly at full speed.

Personally I do not care for this "full speed all the time" and agree with you on that (for different reasons though). Android > 5.0 is so very good at deciding what CPU speed is necessary, that it scales up/down in microseconds, so why letting it run all the time at full speed only generating heat for nothing? I personally would set the Governor profile to performance and let Android decide for itself.
