Do you recommend this version for an erisin radio with 1GB of RAM? I have the Hal9k version of Android 5.1.1 and it is great, but I have the doubt if this version will work just with 1GB of RAM, the issue is that I want to put Android car on my radio and I can not, nor does Mirrorlink let me do With easy connect, I have a Huawei P20 pro, someone can help me, greetings and thanks.

As you can see in the previous comments, yes! The firmware works fine also with 1GB of RAM.

I came from 5.1.1 and I can't flash the ROM. I made the installation in the second thread but it didn't work. I put the SD in GPS slot and USB flash drive in USB port, but after reboot Lollipop, it doesn't go in recovery mode. Any help?

But you don't have 7.1.2 installed, right? In the captures 5.1.1 comes out, I am interested in 7.1.2 with 1GB of RAM, it sure works with 1GB of RAM, it seemed to me that some time ago someone told me that it did not work .... Thanks for answering, I hope your answer.

And since I start to ask, what browser do you have on the radio, is that I had a GPS card with the igo, but I have a very old version, do you recommend another program or update the igo?

About device standby

Hi. I installed the rom on an erisin 1gb ram. When turning off the engine, the device stops. Then, when turning it on, the device reboots every time. It does not enter in standby for two hours. This worked ok on android 5.1.1 and another custom rom. Is there any other setting for standby? Thanks.

If I have version 5.1.1 of this rom and I want to install 7.1.2, can I directly install version 2.5 or does it have to be any lower and go installing updates from the radio itself?

Hal9k on MTCD little problems

Hello everybody:

First, i would like to thank you HAL9K, for his Mod and Firmware that extends the functionality and lifespan of old MTCD devices. Mine came with Kit Kat and now it works better with android Nougat Mod V2.

I just want to report two small problems that maybe somebody here already solved:

1. On the on screen keyboard, it is supposed that if i do long key press, some letter changes for numbers. That is not working on 2.5.

2. I guess that mod comes with some kind of ad blocker, so, i can not see any youtube video; the music starts playing but there is no image. Same happends with youtube vanced or stock app.

Two small questions:

1. I there any way to install a customs recovery like twrp?

2. I know that Hal9k cleary said that that Magisk can not be update or the firmware must be re-install, but what happens if there is no problem to reinstall? if i want to reinstall is there any way to update magisk? or maybe what he really want to said was, that there is no way to update the magisk and if you try i will not work and you have to come back again a new 2.5 firmwre from the scratch?

All answers will be appreciated.

Thanks,

Mauricio F.
[MTCD Software Development] oskarrrrr:
Have you installed this version 2.5 directly with Android 7.1.2? Or is there a base version and then have you been acting? I am in version 5.1.1 of Hal9k, and I am about to upgrade to this one, what do you recommend?

[MTCD Software Development] mflorezm:
I was on 5.1.1 from malaysk, and moved directly to 7.12 with hal9k. I just follow the instructions on the first post of this topic. You need and sd card and a usb pen drive, nothing else. Regards, MFM
[MTCD Software Development] oskarrrrr:
But in the first thread it says that you can install this ROM only with a USB, right? Or do you need both? Usb and SD?

[MTCD Software Development] LizardNerd:
Hi!

Personally I am in the same situation. I got stock 5.1.1 and I want to flash 7.1.2, but it doesn't work because the device doesn't boot in recovery mode.

Any solutions?

I flashed the 7.1.2 firmware with SD_firmware_tool in SD card and pen drive both.
[MTCD Software Development] Modzzo:
mines same doesnt open recovery mode
[MTCD Software Development] mflorezm:
You need the SD to boot on recovery mode, then to hit install from USB.

---------- Post added at 10:16 AM ---------- Previous post was at 10:08 AM ----------

I came from Malsyk 5.1.1, so, it was easy to boot on recovery with the power down menu option, but i really don't remeber how i booted to recovery the very first time on kit kat 4.4. to install malaysk 5.1.1., maybe you can do the same. Please read the malaysk 5.1.1. thread and try to install that firmware, once there is very easy to install Hal9k 2.5, that is great.

Have you tried any to boot on recovery? there a plenty on google play.

Regards, MFM
[MTCD Software Development] oskarrrrr:
But this ROM is not installed like all? I mean I put the file in a USB formatted in Fat32 and I give it to update and I get the update the radio, can't it be done like this?

Hello, am I the only one who can’t connect to the WiFi via HotSpot with this ROM? It connects to wifi successfully, but acts as there is no internet: can’t launch google play, any app that requires network doesn’t work and while trying to browse with google chrome, I get error something like ‘dns_probe_finished_bad_config’. Google suggests that I should change DNS server, sadly I can’t simply change DNS. With static ip option, I need to provide IP, gateway, prefix length and DNS addresses, that I don’t know and have no idea how to get iPhone’s hotspot configuration.

Hotspot device: iPhone Xs. With other ROM it worked just fine, so I doubt it’s phone’s fault.
[MTCD Software Development] Baihurino:
Okey, so I managed to make it work by changing DNS with Override DNS app. So obviously it was faulty DNS, but why?
[MTCD Software Development] korekore1:
anyone knows where can i find the original firmware (HXD model)?

This rom for at least the last 2 updates has almost made my device unusable.

I only use 2 apps (gonemad music player and google maps) and the device acts like i am always out of memory.

Google maps opens 1 out of 3 times without freezing and when it freezes i have to clear cache,reboot and maybe it opens maybe it doesnt.

If the music player is on and plays music and i try to open maps the sound stutters.

This is not how a 4core 2gb ram device acts,something is wrong with the rom.

Anyone else with such problems?
[MTCD Software Development] kabelgleichung:
I think the problem is the need of more and more resources in newer versions of maps. Try switching to microG and use and older version of maps (version is in an older post of mine in this thread). Works great for me!
[MTCD Software Development] korekore1:
i had problems with microG not recognizing my account after some time.

Can you link me the old maps apk or the version number? thanks
[MTCD Software Development] kabelgleichung:
Update the shipped microG to a recent one with f-droid.
[MTCD Software Development] korekore1:
i won't use micro-g again,it has issues.

It didnt make the device faster either.

Hello,

so practically i've lost last 3 days in trying to update my GS HU from Lolopop 5.1.1 Hal9k 1.3.2 mod to Nougat 7.1.1 Hal9k 2.5 mod.

I don't know where to start, maybe first i should say the HU is GS px3 rk3188 1gb 4 cores 7" with gps slot which is running absolutely perfect.

It was MTCD but now the MCU is upgraded to MTCE 3.30 (went through 2.93 before that) - all this is not important but it goes to prove the GPS slot and the SD cards are perfect.

Moreover to proof myself more than anyone else, i reset the HU to stock rom, than one by one i was loading images of the 1.3.x mod to get it back to 1.3.2.

I have to say i did not read the entire thread.

But, i've read all pages from 1 to 134 and the last 10-15 pages, and i allow myself to consider that this as enough and more than anyone else who has a problem before deciding to write.

Proving the HU is totally compatible, the gps card slot works and the SD card works (i forgot to mention above some updates i did from USB stick so it also works) i turn my attention to the process.

So Nougat uses different partitioning,the Lolipop will not recognize a Nougat image so it is important to have a bootable SD card with Nougat recovery, not just slamming the 1.8gig image file on USB stick.

So i download and start /with Admin privileges/ the SD Firmware tool

select the SD card

uncheck "Upgrade firmware' box

select the nupdate.img file of 2.5 mod 7.1.1

click Create and wait the process to Finish. I did this process like 10 times also carefully removing the card with "safely remove hardware etc', then stick it in the GPS slot.

At the same time i copy the nupdate image file on usb stick and push it into the USB1 of the unit.

I hard reboot the HU but it still loads Lolipop. I've done so many formatting and different approaches even outside of the defined process (like QA would do) but nothing. The HU simply does not want to boot from the SD card.

Again, the HU is compatible, it is MTCD/E, it is 5.1 Android, it is PX3 RK3188 it has working gps and usb slots, the process is exact copy of the described by Hal9k in the 2nd post but still no and no, the unit just does not want to boot from the SD card to load the Nougat repair to then start the flashing of nougat.

Please advice and if you don't believe i follow the process as described and don't believe the USB and GPS slot and everything is working i'll have to pay someone to stand by me recording video for youtube to see...

edit: i also tried with version 2.4 of the mod as it's the only one older that i find, just thinking that there may be something prohibiting from going from 1.3x to 2.5 directly - still no.
[MTCD Software Development] opexo:
to continue from above's post, 4th day struggle.

Basically the whole story is to boot Nougat recovery from SD card upon starting the device, right?

And to be sure the device is restarted properly (100% no source of power) - i do it from the fuse.

So today i got new 8gb SD card (fat32 formatted) even tho the old one works.

With SD Firmware Tool i tried any option.

But in the end it does not matter if there is 'tick' on "Upgrade firmware" or not, or on "SD Boot" or not, or no 'ticks' anywhere at all. (yes i use the nupdate.img 1,912,219kb). The unit just boots Lolipop 5.1.1 every time as normal. Even if i reboot it to recovery too.

And it dosn't matter if there is a USB flash (fat32) containing the ROM inserted in usb1 or not.

Please advice. Obviously following the procedure or any other possible combination does not work while the unit is fully compatible.

After updating to v.2.5 (switched to microG) i noticed some issues like:

1- Viper4Android doesn't work anymore. I get a message saying that it's impossible to install the driver.

2- It seems some apps don't recognize the root. When trying to use apps like "Disable App" which requires root, i get the message saying the system isn't rooted!

3- When i try to update Magisk firmware the process fail.

Is there someone who can help?

Should i install a recovery like TWRP? (cause if i go to recovery i can see a default recovery and not an alternate one).

[MTCD Software Development] opexo:
[MENTION=5092263]Hal9k_[/MENTION] please advice on post #2033 and #2031

The HU is compatible and GPS cards+slot are working perfect because numerous times i downgraded and upgraded again several MCUs and your v1.x.x 5.1.1 mod as well.

It's just that no matter what options i use in the SD firmware tool to create the bootable SD card from either 2.4 or 2.5 rom, it does not want to boot from it to load the Nougat recovery.

I just suspect that because of some reason the unit does not recognize correctly what is written on the SD card so it starts loading from it after hard restart.

That reason may be either something read by the tool from the firmware file to be written on the disk;

Or the HU is reading whatever is on the card but for some reason it doesn't start loading Nougat recovery and continues with normal Lolipop boot.

Again, its original GS unit, MTCD_GS_3.40 and it is rk3188 1gb unit

Thank you

Hi,

I use the mod v 2.5 Nougat on my px3 with a 3.3 MCU and microG.

Till I want to locate my px3 everything is fine. Now I would like to sove this 2 Problems:

1.) googles "my my phone" is not working under Nougat. I need annother location app, any experience here about it?

2.) Google Playstore is not usable: I can visit it but the px3 and it's apps are not detected and so I cannot get updates or new apps.

How can I solve this?

thx for tips
[MTCD Software Development] rabenkind:
I afraid, you did not. See the first ten page, there you find a dispute between hal9k and a annother senior member about the way the update is succesfull. I guess it was about where is to store the firmware, but see there. I know by practice it, it solve the problem and the senior memebers way is right. :laugh:
[MTCD Software Development] rabenkind:
Try it with all on the sd card and put it inti the sd slot. and you need patience it takes really time.

anf don not forgott! choose the firmdate update start from gps.

Please trust me i've tried everything. And i really read the pages, not just glazing over them with my eyes.

If you read my posts my unit was upgraded to the latest 1.3, but i downgraded it to stock and then back up again to latest 1.3 so i prove its working - the HU, the card, the slot, everything.

Just strictly following the instructions does not lead to boot of Nougat recovery. Nor is any other combination. Trying with 'tick' or without 'tick' on the 'firmware update' option was amongst first of the many options i tried. Thanks for trying to help but i really feel Hal9k should have a look if he cares enough for this single maybe case. After all he's working on two versions ahead already...

Hi, i got the HU our of the car in my apartment and also got a car battery.

I got SD card and USB stick.

I downloaded the 2.5 rom from google drive and extracted it.

I started the sd card tool as administrator, select the sd card from the drop menu, put a check on "Update firmware", select the extracted nupdate.umg, click 'create' and waited until it was done. Then i pull out the sd card from the PC.

I put usb stick in the PC and copied the nupdate.img file on the usb stick. Then i pull out the usb stick from the PC.

Now to the HU - it is off some 2-3 hours after pulling it out of the car so ZERO power at all. I prepared the necessary wires on the HU plug so i can give it power by connecting it to the battery.

But first i put the sd card in the gps slot.

Then i put the usb stick in the usb slot.

Now i connect the '-' wire to the '-' battery post, then the '+' wire to the '+' battery post and the HU lights up.

At this very point the HU should boot into Nougat recovery from the sd card.

But NO! - the Loipop logo appears again and it just loads the Android as usual.

You see, these are exactly the steps from Hal9k's 2nd post for upgrading from 5.1.1

And as i mentioned my unit is MTCD_GS and RK3188 (i even looked and read this on the PCB inside) with MCU 3.40.

And to anyone reading 1st time my problem - yes the usb stick, sd card and gps slot are working because i'm able to make upgrading/downgrading Lolipop images.

So to answer your post and the typos1 trick - i never get to Nougat boot logo to even be able to try this trick.

Also I tried to go back to different BMW themed firmwares and they are also not detected. Any ideas on what could be the issue? I am really keen to try the Hal9k version.
[MTCD Software Development] rabenkind:
Hi I see you like it comfortable :) unit at home :)

"Clear the "Upgrade Firmware" check box. It's important !" This means there is no entry the box is empty

But furthermore by the way you described. I suppose sd card and usb stick maybe formated with Fat32 but you did it the wrong way. You should format it with your unit, cos this includes the android data.lost and so on Folders.

Then put the data carriers into your pc and do it the way you described with the data.

Then put the carriers back to the switched on radio. Make sure the data carriers are detected by using a data manager and look at the settings/memory, the usb is in slot 1 and the sd card is in the gps slot. (just as you know)
