Is it possible to just root (or add twrp and could root after) to one of these units, without needing to modify the rom thats currently installed?

I have one of these aftermaket units, but made by xtrons.

I would like to add some root apps and hopefully disable some of the stock bloatware. As it is quite slow on first boot (like each time i start the car)

I would like to keep the current rom on board. I dont have any update files for this current version i've looked around but cant see anything. Even the xtrons website has information on the device, but no software support.

So i would like to avoid bricking the unit.

I can post more info on the device if needed.

But i just want to know are these roms protected in any way or are they easy to flash a modded boot.img / recovery without some bootloader security error popping up.?

Hello, I have one problem maybe can someone solve it, I haven't tried rooting before so...

I'm trying to get my head unit connected to a PC computer in order to root and install firmware all over again.

With all help from a videos on youtube it still can get no connection to PC (WIN 10 latest), nothing.

Unit is ALPS FF5000 mtk chipset AC8227L with DSP TDA7851 - 2GBx16GB

I am using igo navigation. Sometimes it finds the gps signal, sometimes it does not find the gps signal. it has nothing to do with the weather or the location of the car.

I used the code 140 and 141 from the advanced settings, for a long time igo navigation shows the position of the car correctly without losing the gps signal, when I turn the ignition off and on the next day, it cannot find it again. I turned the location service on and off in the normal settings, still nothing changed. I think a setting is corrupting the gps signal, does anyone have any ideas or suggestions about this?

Also, the bluetooth name is bt6846, does this change? I made an English translation with the translation. sorry for spelling mistakes.

at the back of unit attch the antenna for gps more firmly, try that and see if loses signal again. Test signal with internl app in android gps test

I bought the gps antenna and removed the old one and installed the new one. I tried again with the built-in gps application, it found one or two satellites again. igo navigation could not find location. How should I set it up, can you help me?
[Android Head-Units] Anton TNT:
there is something interfering withantenna, do you have led bulbs installed in car ? If do led bulbs are most common interferer of antenna signal , DAB+ and gps antennas are affected. If are not led bulbs installed check your version of IGo it may be buggy , install igo again as program and see if then should work.

Hello, I don't know if my question belongs here. I have a Xonrich MTK 8227L 2/32 purchased 2 weeks ago, worked great until two days ago. It started not saving the settings I set. My radio stations are lost after turning off the engine, the equalizer is also lost the settings I made. It's literally like playing it for the first time. Any ideas what it could be?
[Android Head-Units] YİGİT1940:
Did you solve the gprs problem? I have the same problem. It finds the satellites very late.
[Android Head-Units] ertan50:
no I couldn't figure it out. I think it's a software thing. I turn off the GPS from the system settings with the code 140 and turn it back on with the code 141. It detects it without any problems for 15 minutes, at most 30 minutes. then it finds no satellites. Sometimes it finds satellites on its own. I don't try to fix it anymore.

Hello

it seems, that i have shot my Device an Junsun V1 Pro (ac8227L) after "updating" Properly with the "wrong" Firmware it shuts off the screen..

Now it does not react at the USBSticks to revive it,

What i see is, that the screen is glowling lightly and the buttons at the side are ligthing and sometimes blinking..

So i'm optimistic to get that revived... I will do that with SP_Flash_Tool but i cant find any fitting Firmware files.

i just have the UpdateFiles in the the "AutoUpdate" Folder ...

Can someone provide me the correct files to get this device reactivated?

At the Pic below there is the correct FW-Version ... (JCAC10003-OC2-v1.0.97R3_231023_1114_AA0)

Maybe an instruction how to create the Files for SP_Flash_Tool from FW Files??

Thank you
[Android Head-Units] Big_11:
some news..

I tried to revive my device with tht two files 8227L-8.upd and 8227L-8.bin found at an russian forum...

i did as they told put in the USB-Stick , press the reset button and quickly touch the middle of the screen to come to the "recovery detected" ...

but nothing happend....

i also tried to connect it with my Laptop with the flashtool and also adb-shell but nothing worked..

But what i found is, that the drive (esp. the USB Port) ist recognized by the "dead" device !!

Cause i can hear a "Bling" if i press the reset button and release ist.

and, oh wonder, an the stick are written the "usual Android files" as the folders "ANDROID" an "LOST.DIR"...

any further solution to unbrick my device without unmounting it from the car ??? Please !!!

I remember back in the day there was a simple technician menu in all my android phones that lets you change tv out settings like resolution and FPS for when you connect your phone to a tv using hdmi cable.

I have a type c to hdmi and it works great and super smooth with no lag but my tv is 1080p at 16:9.

OnePlus 8 Pro has super wide aspect and i get black bars as well as not seeing the right side of the screen.

How can i change the tv output settings to 1080p at 16:9?

Where did all our old options disappear in these new android versions geez...

Thanks in advance

Hello Forum,

I've been experiencing terrible battery life for these days. I have minimal apps installed on my phone and with background apps killed, I still loose approximately 10% per hour even while I am sleeping. One thing I observed though that WhatsApp for some reason runs in the background despite not being open in the background and restricted too. Could someone please review the attached screenshots and share your views? Thanks in advance!
[Google Pixel 3 XL Questions & Answers] Scythe:
Can you also take a screenshot of full device usage ?

You can get that by 3 dots in battery usage page, maybe google play services is responsible which means you need root or adb permisson'd battery programs.
[Google Pixel 3 XL Questions & Answers] muhammad42620:
Even if you restrict background usage, WhatsApp will mask itself as a foreground app and keep running to fetch it's messages. Honestly speaking, iPhone is way more optimised for these kinds of things.

Hi, I've read through quite a few pages but have no luck finding anyone resolving this issue. It's probably a fairly simple fix but I havn't figured it out yet.

Everytime I install an app through .cab file and choose to install it in my 4gb "external storage" it will not run properly. Everything installs perfectly fine but when I try to run it, it tells me something about not certified or some sort. I can't give the exact wording that WinMo said because I'm running chinese version. If anyone has a fix to this it is much appreciated. Thanks.
[Touch Diamond, MDA Compact IV General] MarcLandis:
Search for sdkcert.cab and install it
[Touch Diamond, MDA Compact IV General] wpichang:
Hi, I've installed the sdkcert.cab but it still does not work... What do I do now?
[Touch Diamond, MDA Compact IV General] wpichang:
bump

so can someone on the forum tell me what I need to do for programs running off my 4gb to work? it seems everything I install on the 4gb will show up saying a trusted cert is missing or one of the file is missing. I'm pretty sure one of you guys out there already figured out how to fix this. Thanks in advance.

P.S.- I already installed the sdkcert.cab but it didn't do me anything or I don't know how to set it up.
[Touch Diamond, MDA Compact IV General] wpichang:
Hi, I've found out the exact problem but I still need some help. This is the issue: after installation completes, if I run the program within my program list it will show up with a message that says I'm missing a trusted certificate or some sort. However, if I try to run the program from the folder I installed in, it will work, so I'm pretty sure I need to adjust something within the registry to adjust where my shortcuts are directing to. I believe this is an issue due to my Diamond being the chinese version. Anyone ran into similar problems or know how to fix this? Thanks.

Hello guys i'm new to the forums. This is the first time i will try to install a custom rom on my device with unlocked bootloader. i did this post because i want to flash a custom recovery then a custom rom but before i do that i want to ''ask first'' since i don't want to brick my device. I've read some post about people having trouble with custom recovery. i have seen that most people have fig-lx1 but i have fig-lx3. So that's why i ask what's the rom/recovery for my smartphone? I want a rom with the best battery life/performance and i want a rom wihtout google apps. I'm on oreo 8.0.0 version(stock rom), thanks.
[Huawei P Smart Guides, News, & Discussion] januxool:
I have the same model fig-lx3, with EMUI 8 and Android 8, I have a reference that EMUI 9 is somewhat slower, so a rom with the features it requests is not available to date, in my case just install L Speed Module + Universal Doze Module or Magnetar + Universal doze, in addition to turning on GPU acceleration in 2d in development options, which sped up my device a bit in gaming when it was slow. disable auto started everything except L'Speed and Magisk with EMUI manager.

I was looking for a different radio app, since the built-in one isn't very good and does not store stations persistently. I downloaded NextRadio, but when it loads it says "FM Radio is Unavailable...... NextRadio doesn't have access to the FM radio receiver in your device". How is it that the stock Radio app works but not this one? Anyone have a good radio app that uses the FM tuner? (Not internet radio). Thanks.
[Android Head-Units] tzac29:

Radio chip is 6625
[Android Head-Units] pizzaboy192:
The radio chip in these units is not presented to the Android system. Instead the radio app sends commands to a dedicated radio module on the amplifier board. The same for the Bluetooth unit, as it's not actually part of the Android tablet.

These head units are two devices that work together. The Android part is basically a tablet that has dedicated apps to talk to the Radio part. The two parts work separate, and that's why all the FM radio apps and stuff are such garbage. They have to send commands to the actual FM module on the Radio board and get back a response about what is happening. In theory it would be possible to see what commands and data the FM radio app uses and write your own to send & receive the same data.
[Android Head-Units] jaytango:
Is this separation of modules also related to why the EQ/Balance/Fade functionality does not work on this head unit? I noticed a few reports stating the same problem I'm having... where the faders have no effect whatsoever. No front/rear fade, no left/right pan, and no EQ change.
[Android Head-Units] jaytango:
By the way, I discovered something today... I was playing music files from a USB drive and lo and behold, the EQ and Balance functionality worked. I started to think about why and I think it has to do with what you said. The reason it wasn't working for me initially is because I was trying to use it with the radio, and since u said the radio is outside of the android layer, that's probably why it wasn't working. But it looks like it DOES work with any audio that's within the Android layer.
[Android Head-Units] Ipse_Tase:
Can confirm what [MENTION=2956368]pizzaboy192[/MENTION] has posted. You will NOT be able to use any sound processing, not even to mute radio during navigation directions because of this funky implementation.

All you can do is root and then replace the radio apk with the macnaughty one that does save stations and (for me) has HD information.

I used this

https://xdaforums.com/android-auto/android-head-units/everything-yt9216b-t4007063

BTW :you probably miss the HIFI flag in build.prop as in my case at least the built in equalizer and spatializer work with the radio app.. Viper4Android however, does not work, despite being complied in and having root access, simply because the audio path from the radio bypasses the OS.

Hi,

I bought this phone in Taiwan without thinking too much of it. The pre-installed Windows Mobile 6.1 is in Chinese - that's fine. But I cannot believe that it doesn't let me change it to an English system...! My friend's HTC Touch lets him do that. How's that possible? I thought changing language would be one of the fundamental functions?

Anyway, does anyone know if I can ever change my Windows from Chinese to English? And how I would do it, if there were ways of doing it?

Thanks...!

[Upgrading, Modifying and Unlocking] katsudon:
what do you mean by "dumping" the rom...? :)

i guess the portege g810 is just not popular enough for people to develop anything for it... maybe i just need to wait...
[Upgrading, Modifying and Unlocking] btprice2001:
From the wiki: "The ROM holds the Operating system and other components such as the bluetooth and wifi stacks. The ROM is accompanied by the Radio, Ext_ROM, SPL and IPL."

Basically if you dump the ROM from your device, the language files can be changed, and then you could re-flash the modified ROM to your device. I'm not sure how to do all of that, but there are many people here that do know. I believe the first step would be to dump the ROM from your device. Please see the following thread:

[Upgrading, Modifying and Unlocking] btprice2001:
NO!!! That would ruin your device. I posted a link to that thread because it contained instruction for dumping a ROM. You can only flash your Portege G810 with Portege G810 ROMS. That's why you'd have to dump the ROM from your own device, modify it, and then flash it back to your device
