Hi,

actually I think I'll do what you suggested, and use the B502 from ru.

The other B502 (huaweidl.com) is tempting, but if something goes wrong I ruin this phone.

I want to play safe, or as safe as it can get.

(Open...

And I learned another lesson from this experience: never ignore OTA updates when they're offered. In the long run, you only end up shortening the useful life of the phone by tieing it to ancient software. I'm already being bitten by this, with apps that I need but can't use.

I'm buying a new smartphone in days, now. After that I'll risk the updates on the Huawei P9.

I didn't know that. Thanks for the tip -- Will do for sure (y)

Ok, good luck and report

If you want to update even further, you can rebrand from L09c432 Nougat to AL10c00 Oreo - but the prerequisite is unlocking the Bootloader (which is not that complicated or expensive for P9, just about 4-5 Eu, installing a program that will read the code that you can later use for your phone for unlimited unlocking/relocking purposes):

Unlock modems, routers and phones with DC-unlocker software

DC-unlocker is universal, fast and easy to use unlocking tool. Supports Huawei, ZTE, Sierra Wireless and other modems, routers and phones.

For AL10c00b540 Oreo look at ROMs section, HWOTA7 thread, get info from the OP posts
[Huawei P9 Questions & Answers] Umb0:
Thanks, will do (y)

Bookmarked the thread -- will report after I settle with the new phone.

Oreo would be sweet. Let's see how the Nougat upgrade goes, first :)

Hello,

I have been following your latest guides and post to update old P9 EVA-L19 from C432B182 onwards in 2021. I can confirm that suggested B210 update was a real life saver. After using HCU Client paid service to change firmware region of an AL10C00 variant to EVAL19C432 (hw,eu) I started getting OTAs. Now from B210 I was offered an OTA for EVA-L19C432B386.

PS: I was worried about that B210 updates from the androidhost.ru being of EVA-L09 but it worked fine for L19 variant once you do the 3 buttons combo.

Regards,

Max.

So OTA still works?
[Huawei P9 Questions & Answers] W00fer:
Did you manage to find a firmware PV to jump from Marshmellow to Nougat?
[Huawei P9 Questions & Answers] devilmax93:
Hello,

Yes it does. As long as you change region to your variant into the EU model. I received at least 3 updates after moving to the early B210 MM initial software build. Wish they released Nougat for the EU single/dual sim someday too. Currently running EVA-L19C432B399 via OTA only updates.
[Huawei P9 Questions & Answers] W00fer:
Weird because I have a EVA-L09C432 single SIM and I don't receive updates via OTA.

It's already on the latest version it says. Maybe because I downgraded from Nougat to Marshmellow via the rollback firmware. But afterwards I flashed the OEMINFO and locked the bootloader and uninstalled root.
[Huawei P9 Questions & Answers] W00fer:
The problem with that is that it's C150 and not C432 (Europe)

Hi everyone,

I would like to further update my old Huawei P9, but since there ar no available FullOTA-MF-PV downloads on huawei-update.com or huawei-firmware.com I am stuck at EVA-L09C432B210 with Android 6 and EMUI 4.1.3. I started with B182 and updated to B210 with a FullOTA-MF-PV file and dload.

Does someone have an FullOTA-MF-PV update file (something like EVA-L09C432B387) to get to Android 7?

Thanks all, finger crossed ;-).

[Huawei P9 Questions & Answers] Jan379:
Thanks but both, the EVA-L09_C432B383 and EVA-L09c432b504 from your files do not work with dload.
[Huawei P9 Questions & Answers] zgfg:
It's been long time but are you sure? Did you unpack the archives to your PC and inspect their content (do not just try to use the zip as is for dload). The " androidhost.ru" firmwares should contain a doc with Huawei oficial service-shop instructions what and how to use for dload.

However, they usually also contain the matrix, from which firmware versions they can be applied.

IMO, b504 could not be applied to your b210, but maybe b383 could be
[Huawei P9 Questions & Answers] Jan379:
Hi,

I properly extracted the files and put them in the dload folder as I did with the B210 update. Whatever I do, the update fails. I even tied another B386 Foll OTA-MF update, same here. Went for TWRP. Unfortunately the update starts in TWRP but fails after ~30%. Reaching fastboot again was pain in the ass. I had to go back to B182.

Thanks a lot. I will head fo a new smartphone ;-)

[Android Head-Units] ludditefornow:
Hi all, I have an Australian 2011 Kia Sportage Platinum model - I think it was SX / highest spec model in other countries. Apparently the Australian car in 2011 was a little unique in that it had a 6 stack CD but no sat nav on the head unit. There is a factory digital amp and sub woofer located in the rear. As much as I have attempted to get this fact across to suppliers on Aliexpress, I am sure they did not fully understand and have suggested I only need a CAMBUS and I am good to go.

As you can see with the pinout for my radio on connector A I have SPDIF ground, DN and DP. So it is a discrete signal to the amp that decodes what I assume is PCM and then sends it off to the speakers. I have a few questions:

1. Before I install the 7862 Unit, I will check voltage out from Pins 6 and 15 on my factory radio with sound on. I assume this will be less than 5 volts. as per SPDIF coax spec. I will then connect up the 7862 unit, plug in an RCA to the COAX SPDIF out and check voltage. If the wiring loom that I have been sent doesn't work, this COAX out feed fed into my car's wiring loom along with a 12v signal on pin 14 (remote AMP) will get me started. Any thoughts?

2. On Connector A of my original head unit, there are the SPDIF outs but why are there also speaker outs for front and rear left and right if there is a digital signal to the amp? Does this mean that the amp is only feeding the sub woofer and that the fronts and rears are fed directly from the head unit? It seems very strange to me.

3. PIN 9 on Connector A is DETENT. What is that? PIN 14 is Remote AMP. Is this a 12v line to wake up the amp?

4. Chinese Unit wiring shows a CANBUS but I am unsure is the CANBUS has an analog to digital converter? Can anyone shed light on this?

I appreciate any assistance you can offer.
[Android Head-Units] TorstenH:
This could help regarding SPDIF: https://www.gencoupe.com/threads/help-spdif-preamp-input-nav-premium.106094/

Are you sure the China head unit has an SPDIF output?

I think your OEM radio supports both. SPDIF and analog output. Or there is a cheaper variant available which only supports analog output. You don't need this connectors when using SPDIF.

I don't know Detent but in another forum they just ignored this pin.

Remote Amp is 12v signal for the amplifier. So you're right.

The canbus converts digital signals from your car to the radio. E.g. Translates the steering wheel buttons to a signal the head unit can interpret.
[Android Head-Units] ludditefornow:
Hi, thanks for the link.

I am sure the chinese unit I purchased has SPDIF out via TOSLINK and coax but not through the main head unit wiring.

There definately is a cheaper model of my vehicle that didn't have a digital amp but I am suprised that there is both direct digital signal to the amp as well as direct wiring to the speakers. It is very confusing.

I understand CANBUS has a high and low signal but I wasn't sure if they specifically also change digital audio signals as well as well as the standard CAN signals.

I believe some CANBUS may handle both the CAN high / low transfer and have the ability to to convert the analog signal out of the android head unit to an SPDIF line level PCM (assumed) signal that my amp needs.

I guess this is not a common subject here. I might have to wait and do a fair bit of testing before I install. :)
[Android Head-Units] TorstenH:
Connecting a china head unit can be a real challenge, especially because there is zero support from the seller.

I've seen the amplifier has separate inputs for navigation voice (pin 9 and 23). Sorry for the German link:

Kia Sportage - Externer verstärker Bauteile und bauteile-Übersicht - AVN-System

Maybe some audio signals will be transferred analog. You could connect the new device without the analog audio connections to check if they are really required.

Can't help you regarding CANBUS but I hope you keep us updated and give some updates of your "project".

[Android Head-Units] ludditefornow:
Thanks again. The problem I have is that my head unit has SPDIF out, USB out rear cam out but all connected to the two white plugs. This unit seems different to all the US, Europe and other Asia models. It might be why I am getting so many blank stares.

I'm even having trouble finding an Australian edition of the wiring diagrams.

Your helpful link to the QL model German manual also has an SL model which is my model. Unfortunately my radio is not amongst the option in the manual. I see radios offer Sirrus so I am assuming that is a US model.

I might just need to go back to first principals and really understand my head unit before I do any installing. How is your install going?
[Android Head-Units] TorstenH:
My installation was a little tricky because I found three wringing diagrams which could be the correct one.

Fortunately all the wringing diagrams had ILLU and REVERSE on different positions so I was able to identify the correct one with a multimeter. But I wasn't able to find the wringing diagram with the model name of the device.

I have a Kia and finally the needed wiring diagram was from a Hiunday device. Someone crosslinked from a Kia forum to a Hiunday forum.

I had to completely re-wire and enhance the black plug of the China head unit because AUX and MIC are separate outputs on the China nav unit.

On the other side I had to remove USB from the black connector because this is a separate plug in the Kia.

For you the USB pins may are another good pins to check if the writing diagram is the right one.
[Android Head-Units] TorstenH:
I'm sure you already found this regarding the DETENT mystery:

Any radio wiring experts know what "Detent" leads are for?

But I think DETENT is PARKING/HAND BREAK. So that's easy to verify.
[Android Head-Units] ludditefornow:
I think there is still a little mystery for me, but I will work it out.

You were lucky to have the option to eliminate 2 of the 3 wiring diagrams. I will do the same before I start wiring the new HU.

Yes, I will be doing a double check of everything.

I *think* that I have worked out why there is SPDIF line level + and - to the amp as well as wiring direct to the speakers from the factory HU.

I *think* that when I use and AUX input from USB or 3.5mm which is analog input, the factory headunit does no conversion and just amplifies the analog signal and sends it to the 4 main speakers. It will be simple to check this.

If I am correct, only CD and radio singal gets converted to digital line level SPDIF PCM then gets sent to the amp.

As my radio has a COAX SPDIF out, I might be able to make a single RCA to double RCA cable to send the signal to the amp. Or I might just patch in the SPDIF COAX RCA into the main ISO plug directly. I think having the COAX SPDIF out from my new HU will give me a lot more option.

I need to check if the CANBUS converts the analog signal to SPDIF line level or if the Chinese wiring just bypasses the amp and sub woofer or does something else again.

My new HU will arrive tomorrow of Monday so I will get time to study the wiring and make some checks. I will be sure to document all of the things I find. I just need to make the time to do it.
[Android Head-Units] ludditefornow:
Well after a quick plug in and test, I am not getting any signal to amp regardless of how well I have followed the supplier's suggestions.

I think the standard signal to the amp id not happening so the amp is not waking up.

Canbus is for a 2015 Sportage but steering wheel options work with the volume working in opposite.

Will investigate more tomorrow.
[Android Head-Units] ludditefornow:
Installed the radio today. The radio supplier's suggested installation did not work as I was sure it wouldn't.

After considering options, I chose to use the coax out and patch that into Connector A pin 6 (SPDIF DN) and pin 15 (SPDIF DP) and everything worked fine.

Some things to note:

1. Canbus worked although the steering wheel volume controls are reversed. Not sure if that is easily changable. I might just live with it.

2.The supplier actually sent me quite a bit more than I was expecting. There were extra patch cables and an external mic. This was nice, but I actually bought a mic thinking that one did not come with the kit. It was only a few dollars though.

3.There is very little installation info. The info by way of photos I was sent did not match the cabling that I had.I would have liked to get an understanding of all the pin outs including the CANBUS but I am yet to receive this.

3. I actually removed my factory radio last night and just powered up the unit. I didn't realise that the default setting in the software is to only put the unit in standby or only turned off the screen. This drained my battery over about 18 hours. I needed a jump start to get the car going and I now have the battery on a trickle charge to repair it.

This default setting allows instant on for the radio. By changing to the option for a three second delay, the radio needs to boot on car starting.

4. Boot times are quick. I have not timed it yet, but I would guess 20 seconds. Bluetooth connection takes about another 20 seconds after that. I will make a video of it and more when I have used the unit a bit more.

5. The radio fascia brackets weren't installed properly. Just make sure to check them before you install. The screws really should be a bit longer to stop threading the fascia mounts.

6. The fascia is not a perfect match for my dash in colour but it still looks good. The fit is not perfect but good enough. I might remove the dash again tomorrow and just pack one side of the fascia so it is more flush fitting but it would only be 3-5mm.

All in all I am very satisfied. The response of the unit is great and sound quality seems good. Bluetooth and wireless connected well and a quick test of the 5ghz frequency wifi tethered to my phone gave 6mb/s when I was downloading the Waze app. I will test more soon.
[Android Head-Units] TorstenH:
To 1: Isn't there a setting in Android car menu where you can assign the buttons to specific functions?

To 3: same topic here. I can set Sleep to on or off. But can't set time how long to sleep before shutdown.
[Android Head-Units] ludditefornow:
There is that function and I did try to use it. I was long pressing on the physical button before pressing the on screen as suggested but there was no change. I assumed the button remap is only useful for non Canbus driven buttons. I could be wrong, though.

I too would like a full understanding of the sleep function. Things like when sleep starts, when shut down starts etc would be useful.
[Android Head-Units] Storrsy:
I hope you got this sorted. If not, have you tried this?
[Android Head-Units] Storrsy:
I Installed in my SL Sportage Platinum today and have no sound and no reversing camera. Do you have a photo of how you wired from the SPDIF on the unit to the factory connector?

Did you keep the factory camera? If so, what did you do to get these working? I think my unit is slightly different as I don't have the small clock.
[Android Head-Units] ludditefornow:
Did you use the coax out method? The Kia amp requires am PCM digital signal sent on two wires as mentioned above.

Get an RCA male male cable. Cut on end and strip until you see two bare wires. These bare wires will patch into Connector A pin 6 (SPDIF DN) and pin 15 (SPDIF DP) of your car's wiring loom. These are the wires to the amp.

Add this male connector end of the RCA cable into the RCA digital out on the head unit. Check for sound.

My reversing camera is built into my rear view mirror so the wiring is not connected to the radio. And yes, I found the switch for volume, but thanks for letting me know. It might help someone else.
[Android Head-Units] Storrsy:
Success!!! I was able to get the amp working thanks to this thread. I was also able to get the camera working by splicing the 'unused' green reverse wire from the supplied harness to the brown reverse signal wire in the CANBUS connection. (I noted that in the some of the offical images the wire was pink.)
[Android Head-Units] starkiez:
Peeps, did you have to connect the remote amp (12v positive?) or SPDIF ground (12v negative?) I’m almost there just no sound.. I’ve connected coax out to pins 6&15 but nothing
[Android Head-Units] ludditefornow:
From the modifed coax cable coming out of your head unit, what voltage are you getting on either wire when playing audio?

If you aren't getting a signal, then there is a software setting (that I can't think of right now) or another issue.

And I have not connected the remote amp wire. Clear photos help a lot if you have followup questions.
[Android Head-Units] starkiez:
Zero volts
[Android Head-Units] ludditefornow:
Then the headunit is not passing a signal to the spdif RCA out for some reason
[Android Head-Units] starkiez:
Yea, seems that's way. Optical seems to be on, weird...
[Android Head-Units] ludditefornow:
Then it is a setting or a faulty unit. If I remember correctly 3368 is the factory settings. Play in there and check. Change a setting, check for voltage. Rinse and repeat
[Android Head-Units] starkiez:
Bought an optical to coaxial converter box, usb power. There's 3v or less when playing music but no matter how I connect it to connector A, there's still no sound. I've tried SPDIF ground and SPDIF -, as well as remote amp (+12v) and mixing and matching the SPDIF pins, but no luck!

Well shoot! I've purchased a Junsun V1 pro (7862 clone) and my Kia Carens also has one of these new fangled spdif amplifiers it turns out. For me it is a bit more problematic as the unit does not have a spdif output. I checked all pinouts and it is simply not there. So I was thinking of maybe modding the unit to have spdif out. I'm pretty comfortable with a soldering iron but have not found any guides in doing this.

Alternatively I've read about canbus boxes performing the spdif conversion. (Though that solution is not ideal as I will be doing AD conversion and then DA again.)

2 questions:

- Has anyone ever modded a spdif interface into a 7862 unit, and if so how?

- Do any canbus boxes exist that can do the AD conversion on the analog output of the head unit?

Thanks in advance!

@ludditefornow: I was just re-reading your original post and notice that the canbus in the picture HY-SS-04 is connected to the line-out of the head unit. Does this box do the analog to spdif converstion that I need?

@Storrsy: does your headunit have spdif out or does the box provided with the cable perform that conversion and have you connected that to the line out of your radio?
