Hizpo OK Google

I still have not figured it out. I have tried USB mic as well and nothing works.

Only way I can see this working is to edit the build.prop, mixer_paths file that contains the code to tell android which microphone to use. I found a tutorial online but it requires root..which is not obtainable on these units at this time. I have sent a message to the supplier and they told me there is only 1 Factory Settings code and it is for the start up options but nothing more.

Here is the link to mixer_paths.xml from OP_Main_Mic_Bypass_V3 zip. Flash via wireless ADB and give that a shot.. I have not tried this nor have I tried wireless ADB from this HIZPO unit so I have no idea if this is a feasible option.

I have the same Hizpo mtcd xrc_V2.54a_1 w/2gb 7.1.2 but mine is a 7" universal. How does your VW version have a working microphone input to android to be able to use google voice? Is there something different with the VW version? Did google voice work before you installed the filter but the mic was too noisy?

I have no microphone input for any android voice recorder or google voice. I am missing voice input under keyboards in settings. This is what I've heard for all those like mine.

Both internal and external mics work together on bluetooth ok for me but no where else. I cannot shut off the internal mic with the external. I've tried a usb mic too but that did nothing.

What's the secret?!? It cant be just a line filter.[/QUOTE]
[MTCD Android Head Units General] typos1:
[/QUOTE]

The internal is usually wired to Android and the external to the MCU controlled BT card, so the internal should work for google voice, have you tried unplugging the external and using the internal for voice ?

There are a few ways to sort out mic issues, see various threads in the MTCD forums and also the MTCB forums.

Hi all,

I got this unit to substitute an infuriatingly slow MTCC 1Gb. It's incredibly fast in comparison! I had a few issues with Bluetooth and Factory Recovery but contacted Hizpo and they sent me the link to their latest firmware. I'll leave it here in case anyone needs, or if anyone wants to use it as a starting point for mods.

Hi,

Can you let me know what the build number is on this firmware?

Thanks
[MTCD Android Head Units General] typos1:
The fix for your MTCC unit would have been to install an openG or microG ROM, or install an extra Gb of RAM - the reason this one is faster is the extra 1Gb or RAM.
[MTCD Android Head Units General] jpt000:
Yes, I'm aware of that. But there are other bonuses - the head unit starts almost instantly when I turn the key (1-2 seconds at most instead of 20-30 from the MTCC). If I understand correctly the installation of an extra Gb of Ram is not something one can do in his back yard...
[MTCD Android Head Units General] typos1:
Boot time is improved by extra RAM and also by using openG/microG.

Installing RAM depends on your skill level, some people can do it others cant.
[MTCD Android Head Units General] kiru:
I too am curious how you got it to work. I have the Hizpo 2GB 7.1.2 (custom fit for Honda CR-V) and I can't get any Android service to recognize or hear any of the mics. As the previous poster stated, the mic only works for BT calls. Mine is a MTCD_XRC_2.58_1. The seller where I bought it told me that Google voice doesn't work with the mic.... But then again he told me my scantool sx (usb obd reader) wouldn't work as well, but it works perfectly fine, as I couldn't get my BT obd to pair.
[MTCD Android Head Units General] jpt000:
Do you have a link to info on how to install the memory? Can't seem to find any... Just the group buys.

Thanks!
[MTCD Android Head Units General] typos1:
All the info is in the group buy threads.

You can change the MCU type - see the "Cross Compatible MCUs" thread.
[MTCD Android Head Units General] ignos:
ok, thanks. But now i have a problem. My display is green and flickers. Have someone the problem before? Do you think hardware or Software Problem! Factory reset fixes not the damage
[MTCD Android Head Units General] typos1:
Did you read the cross Compatible MCU thread FULLY before you did it ?? Did you export your mcu.cfg and flash it as well ?

And I dont understand why you are posting in this thread about it ? - Any problems with flashing other MCUs should be posted in the Cross Compatible MCU thread - people who have done it can help.
[MTCD Android Head Units General] ignos:
i dont flash i untill now or do something else. the display Problems have coming during i was driving the car, so i post this in thread because i have a hizpo headunit.
[MTCD Android Head Units General] typos1:
Did I misunderstand ? - you meant "thanks" for telling you about the MCU and you havent flashed it yet and now you have a screen problem ? If so, sorry.

Flashing another MCU may help as the MCU has control over the screen, of course it may not help also.
[MTCD Android Head Units General] ignos:
I'm sorry too, I have written it misleadingly. Yes i wanted to flash but before i could do it the radio get the problem. Ok, thanks again i will try to flash it, maybe it fix the display, but i think its a hardware issue.

Hi All,

I am planning to buy this device from Aliexpress (not branded as Hizpo) and i asked the seller for the device details (see attached picture as well)

MCU : MTCD_XRC_v2.52_1

The seller advertise the device having 2GB RAM, 32GB ROM, Amp IC TDA7850 and Radio IC NXP6686. Is this correct ?

Also I currently have the factory radio from the Manufacturer with GPS and Telephone cabling. Anyone knows if the car cabling will work with the android device or i have to replace them ?

Any impressions from sound perspective ? Good, bad ?

[MTCD Android Head Units General] typos1:
Thats an XRC unit, a lot of people are complaining that the nic only works with the BT app, ie not with Google Now or other Android apps, so if you want that functionality I would not buy an XRC unit, at least not until the problem is sorted.

You should be able to use the GPS antenna from the car with these units, I assume you mean the mic when you talk about "telephone cabling" you may be able to use it it depends.

Hey, has anyone had experience with the newer Hizpo 4GB Cortex A53 Android 8.0 head units? Same root process etc as the older models?
[MTCD Android Head Units General] sev:
I have a hizpo I bought off Amazon. It is a XRC unit as well, BMW specific. Most everything works perfectly except the a2dp streaming is TERRIBLE and nothign I have done has fixed it. I contacted Hizpo, which their website is horrible, there is no support contact. I could not get a hold of them on amazon, so I tried them on ebay and they told me they cant help me because they cant look up my reciept and I didnt buy it on Ebay. Basically expect 0 support, especially if you bought it off amazon.

anyone else here have really terrible a2dp bluetooth music streaming issues with their XRC units? I wonder if it just me with a defective unit
[MTCD Android Head Units General] typos1:
There can be problems with BT on these units, as Hizpo is a seller only and you have an XRC unit, you ll be better off searching threads about the BT problems as its down to the BT module so effects units from all manufacturers using those modules. What module do you have ?
[MTCD Android Head Units General] sev:
It's a PX3 with a Md-725. Everything sounds good except BT A2DP
[MTCD Android Head Units General] typos1:
Look in the MD725 threads for a solution.
[MTCD Android Head Units General] sev:
Took a look around many threads. The only issue is see fixed with md-725 is with the echo fix, which has to do with phone calls. Nothing with music
[MTCD Android Head Units General] typos1:
Well search the forums for a2dp issues then, I ve deffo seen some people post about it before.

But this thread isnt very likely to help you.
[MTCD Android Head Units General] sev:
The only thing I wanted to know from others in this thread if theyre seeing the same problem I am. I have searched extensively on a2dp issues on all the mtcd forums and information is inconclusive. There's maybe 4 or 5 threads on A2DP and one that talks about the problem i have and the last post is from october 2017 with no resolution.

I'd like to narrow down whether its my specific unit or other XRC units seeing the same problem.
[MTCD Android Head Units General] typos1:
Ok, it seems youve done all you can apart from asking people in those threads with a2dp problems what units they have. There is also thread about usb BT devices, you could see if anyone in that thread has a better experience of ad2p with a BT dongle.

Ok, you have an XRC MTCD unit made by Xinrui Electronic Technology Co. Ltd, Hizpo are a seller only so not relevant for anything other than any warranty they offer.

Its deffo MTCD/E, had to check cos we get a lot of people who dont.

Are you using the standard ROM ? If so you probably arent rooted.
[MTCD Android Head Units General] TPlatt:
Yes. I'm definitely not using another Rom. I've only opened it and installed it. Never tried to root or anything. However I know that I am not rooted but my psvue app says that I am. Is there anyway to make it work?
[MTCD Android Head Units General] typos1:
Dunno, never used it or even heard of it before.

Dont know how a non rooted device could show as rooted to an app either.

Is the unit secondhand ?
[MTCD Android Head Units General] TPlatt:
No. I bought brand new. I just don't know because it's not pure android if it was picked up by safety check by the app.

I mean it is a radio that has settings referring to it as a phone. So maybe there's an issue with it thinking it's rooted.

---------- Post added at 12:22 PM ---------- Previous post was at 12:21 PM ----------

Sorry to double post. But is there a way to run magisk and use magisk hide to get app to work. I understand I would actually have to root but don't know how to do that or if that's even possible on this particular head unit.

---------- Post added at 12:24 PM ---------- Previous post was at 12:22 PM ----------

Also psvue is playstation vue. It's playstations version of cable that can be accessed via smart devices along with their consoles.
[MTCD Android Head Units General] typos1:
Ok, asked if it was used as someone else may have flashed a ROM on it.

It is pure Android, the term "pure" Android the term came about when a few years back some car stereos would boot to a non Android basic OS or WindowsCE and then to get to Android youd have to press another button, all MTCB/C/D/E units are "pure Android".

I realise that its some sort of PS app, its probably looking for safetynet and cant find it so thinks its rooted.

What I would recommend is to flash [MENTION=5092263]Hal9k_[/MENTION]'s ROM, its a custom ROM - these units run best with custom ROMs as these remove most of the bugs and open up extra features and possibilities. The ROM is rooted, some of his other ROMs come with Magisk, not sure if his Nougat one does though, but youd certainly have more luck sorting your problem running that ROM than the factory one, plus your unit will run better anyway. Then I d post in the thread about his ROM if you need help getting the app working rather than here, as this thread is only likely to attract people who bought their units from Hizpo, yet there are 15+ manufacturers of MTCD/E units that work the same as yours, so youre massively limiting the number of people who could help.

There are posts about rooting Nougat, so you could go down that route as well if you wanted, if you still have no luck try opening a new thread about getting psvue running.
[MTCD Android Head Units General] TPlatt:
OK. Is there a link to guide me in right direction. Because if I flash a new Rom. I would want to run rooted on android 9 if possible.

---------- Post added at 02:00 PM ---------- Previous post was at 01:57 PM ----------

Nevermind. Rather root android 7.1.2 and have magisk to run xposed and Sony framework. But I definitely need a guide to do so.
[MTCD Android Head Units General] typos1:
You cant run Android 9 on an RK3188/PX3, Android 7 is the highest, changing the SoM to an RK3399/PX6 or an RK33/PX30 are the only ways to run Android 9.

The thread about the ROM is in the Software forum, clearly marked "Hal9k_ Nougat".
[MTCD Android Head Units General] TPlatt:
OK. I'll look into it. Thank you for all your info
[MTCD Android Head Units General] TPlatt:
So I posted a comment and haven't heard back but what version magisk will that Rom come with. Just trying to get everything planned out so I can hide the root once installed. Not sure if you know but figured I'd try since you've been so helpful already.
[MTCD Android Head Units General] typos1:
As I said before I m not sure it does come with it, I said it may do but at least you ll have root and therefore more options to sort your problem, also you ll have a much better functioning unit.

As I also said you unit is NOT rooted, it doesnt have safetynet so thats most likely why the Sony app wont work - apps where digital rights are an issue have to pass safetynet checks to run.
[MTCD Android Head Units General] TPlatt:
So how would one add a safety net bypass is there even is one?

---------- Post added at 08:00 PM ---------- Previous post was at 07:34 PM ----------

Because how would bypass with magisk if there was none in the first place. I'll have to give it a try soon but unfortunately can't try right now.
[MTCD Android Head Units General] typos1:
I ve no idea, but to sort it youre probably going to need root, which is why I suggested the ROM and of course theres nothing stopping you from searching "magisk" in [MENTION=5092263]Hal9k_[/MENTION]'s Nougat thread and seeing what comes up, after all I said I didnt think his Nougat ROM had it, not that it definitely does not . . .
[MTCD Android Head Units General] TPlatt:
Exactly. I'll give it a shot as soon as I'm able to
[MTCD Android Head Units General] TPlatt:
Successfully flashed the new Rom and I'm enjoying so far. I have magisk installed (v17) anyway to help me with the rest?

I also got Sony framework flashed via magisk as well. But still don't seem to "see" psvue as app in the play store.

I wasn't able to flash remote play enabler. I'm guessing I need a newer version of magisk, and can't seem to find an answer on whether I can or cannot upgrade magisk on this Rom you directed me to.

Also on magisk it doesn't pass safetyney check because I'm guessing it's missing something. Not even sure how to add what it's missing.

If you could help me in the right direction, I would be extremely grateful. Thanks for your time.

Hizpo 7.1.2. DVR picture not works

Hi!

I have a Hizpo 7.1.2 Android headunit. Everything that works superbly on it (rear view camera, steering wheel control, net, GPS, etc.) However, the picture of the USB DVR does not appear on the radio.

It does not work with the head unit's own app or with the camera's pre-installed app. The camera recognizes the internal storage as USB1. It shows the factory files available on it. I'm installing ucardvr.apk on that. It will be installed. Then, after opening the app, you won't see the 32GB SD in the camera. I can't format it (no TF card), I can't view the camera image on the head unit, or the videos I recorded. Otherwise, the camera will record the video on the SD card.

The factory settings are on a DVR USB disk.

I tried two different cameras. None of them work.

I'll send you a video:

[Samsung Galaxy S7 Edge Questions and Answers] kailashnj:
Guys need help urgently.

Today i uninstalled a software called smule and it caused by phone to hang. This automatically restarted my phone and was stuck at the Samsung Logo.

Tried to do soft reset did not work, tried wipe cache from recovery did not work. When I try to mount from the system recovery it will not connect to my PC.

I have 40 GB of pic and videos on my phone which I just can't loose. Need to recover anyhow. Hence one option that i can think of is using the TWRP recovery and mount the phone and copy my important data to pc.

My phone is the 128 GB version Black Pearl. Box say SM-g935FD1

Please help as the data is very precious to me - I don't mind loosing all the apps and settings but can't afford loss of data for me.

I can enter recovery mode and download mode. But can't enter the safe mode.

I have downloaded the following twrp-3.1.1-0-hero2lte.img and ODIN.
[Samsung Galaxy S7 Edge Questions and Answers] NonXtreme:
Forget twrp. This thing require your /data to be formated first to be able to read data.
[Samsung Galaxy S7 Edge Questions and Answers] kailashnj:
Is there a way to get the data back if formatted.

Cant I install the TWRP and boot to the recovery and mount the disc to read. Even that will not be possible ?
[Samsung Galaxy S7 Edge Questions and Answers] NonXtreme:
No.

TWRP can't mount the disk because it is encrypted.

Data on S7 are encrypted by default.

You need to remove encryption by formatting before twrp be able to mount the disk. So any data before being formatted will be lost and unrecoverable.
[Samsung Galaxy S7 Edge Questions and Answers] ForbEx:
No way to recovery. NonXtreme said it as it is.
[Samsung Galaxy S7 Edge Questions and Answers] doctor_vai:
Just don't do anything that might compromise the data. Wait until someone with experience shows up and meanwhile take it to a samsung store. They might have the tools to bypass whatever causing the bootloop.
[Samsung Galaxy S7 Edge Questions and Answers] DSA:
is 4 years on xda and over 350 posts not experience?

NonXtreme was correct in what he posted, so why are you saying ignore him?
[Samsung Galaxy S7 Edge Questions and Answers] mmotti:
Damn man. Really need to make regular backups to avoid this :( my first thought would have been TWRP but of course, as the guys above had said, you simply can't mount /data unless you format it first.

Was it simply an app install? I've never had this sort of thing happen over a simple install.

DON'T DO THIS YET. WAIT FOR FURTHER FEEDBACK.

Guys, could he install fw over the top with odin and home_csc to try avoid wiping data or does this still present an issue with encryption?

Or maybe even just the AP? I can't remember exactly which options wipe data and which ones don't.
[Samsung Galaxy S7 Edge Questions and Answers] b99721:
Maybe you can try flashing with HOME_CSC. If I remember correctly that doesn't wipe anything - apps and data all remain as-is. Only point where you might be stuck is that during the flashing process or at first boot it will ask for a Pin, and if you have not setup a start up pin in secure startup, you can simply enter "default_password" (without quotes - used to work with older firmwares for S7 edge, but I think I read somewhere that this pin trick now doesn't work with latest one) - so maybe flash the latest and try, if that doesn't work flash an older firmware (with HOME_CSC) and boot and connect your phone to pc and recover - though phone will keep throwing force close errors, and once data is copied flash latest with CSC (instead of HOME_CSC) to wipe the phone clean and start afresh.
