[Android Head-Units] ultimax_sg:
Hi!

I'm new here and am wondering if someone could help me out.

I got an Android headunit through a local workshop. I thought it'd be an upgrade, and in some respects it is, but it's been giving me endless problems. I've also eventually come to the realisation that the mechanic is pretty clueless about troubleshooting software issues (I suppose he's more of an installer) so I'm pretty much on my own here. He's talking to his supplier but has been established these Chinese suppliers aren't usually helpful.

There are 2 things which I can't figure out:

1. On day 1, the bluetooth worked. I could pair my iPhone with the headunit through the unit's stock "bluetooth/dialer" app. But the unit wouldn't power back on after it was installed the first time. Mechanic told me the the unit came shipped with a wire switched around and once he corrected that problem, the headunit has been working pretty reliably. Bluetooth stopped working after this, however. I've done a factory reset, tried the RST button upfront but to no avail.

I've go to settings and searched for "bluetooth" (yes, noted that it's hidden on these units!) and made sure it's switched on. Occasionally, I see my phone's name appear on the "settings" page, but I can't pair it with the unit. It remains stuck on "pairing." It still searches endlessly in the bluetooth/dialer app.

Is there anything else I should look into?

2. Can the OS and firmware be upgraded on my unit? I unfortunately, have no idea what brand/model the headunit is. My car's pretty rare in my country (Renault Clio 2015) and the headunits on Aliexpress were for a lower-end version with different connectors. The workshop got a unit for my model through its Chinese contacts, but it came in a non-descript box. Here's the info I've gotten from the Settings screen:

Processor type: QuadCore-T3

Android Version: 7.1.1

MCU version: T5.3.21-63-9B1-C06101-180904

System version: V8.3.2_20180919.193359_ZH5-N

I'll be going through the forum to learn as much about Android headunits but would appreciate any help in the mean time.

Thanks!
[Android Head-Units] ultimax_sg:
Spent some time looking around the forums. Thought I'd log what I've discovered for others who may be searching for similar info.

To recap, I have an Android head unit with no branding. Initially, all I had was the info from the "about device" screen, which provided a bunch of numbers.

I got more information by downloading a hardware info app. There are a few but they generally work the same by providing you with more hardware info (ie. clues).

Discovered I have an Allwinner T3 P3 system. I'm sure I'm lumping several things together but it was enough info to search the forum with.

Discovered this wonderful thread which is generally about Android units based on the above chipset.

Within that thread I came across this one which was extremely helpful. It details how there are 3 types of Allwinner T3 P3 systems which are all different as far as firmware is concerned. Links to their respective firmware are provided, as well as some info on how to reset/recover the system. Glad I found this as I have a better idea how these things work, and more importantly, it cautions against what NOT to do (and risk bricking your headunit).

The the post also links a Russian site that has even more info on my unit from the Allwinner T3 P3 family. Will explore this next (thanks Google translate!).

Will also try to do a factory recover to see if I can fix the bluetooth problem. It worked on Day 1 so at the very least I know the hardware works. That said, who knows if the hardware was fried when the wires were switched around.
[Android Head-Units] ultimax_sg:
Solved the bluetooth problem. Answer was in the Russian thread posted above!

Thank you, just got a unit with same MCU version and your post has helped me identify this thing!
[Android Head-Units] jmouin:
Hi Ultimax,

I have a small question. I have the same car as you ( a 2015 clio 4) and I'm wondering about the Canbus configuration to use to get the steering wheel boutons to work? Looked everywhere and nothing on this topic so I'm really waiting for your directions..
[Android Head-Units] ultimax_sg:
Hey!

Glad to help!

What headunit comes installed in your Clio 4? Is it a R-Link TomTom unit (without the USB port next to the screen) or the more basic MediaNav (with the USB port next to the screen)?

If it's the MediaNav headunit, you're in luck. There are quite a few aftermarket Android headunits which are supposedly plug and play, including steering wheel buttons. At least that's what's claimed. I know Pioneer Europe has a headunit which is a 1 for 1 replacement for the stock unit. It even comes with a new plastic front so it fits perfectly and a new wiring harness.

https://www.pioneer-car.eu/eur/products/sph-evo62dab-clio

If it's the R-Link TomTom unit, then I'm afraid you're out of luck. This is the version of Clio 4 I have unfortunately. I've searched high and low on the internet for a suitable wiring harness+CANBUS which would allow me to use the factory steering wheel buttons but couldn't find any. The closest I came was one I got from China through a local installer, but only the volume and channel up/down buttons worked. The Android headunit itself which came with the CANBUS was sh!t and I was tempted to go back to the factory unit. Only thing keeping me from doing so was I'd already spent too much time and money getting it to work somewhat.

However, I recently installed a new Pioneer headunit. My local installer managed to replace the Android unit with it. He couldn't get the steering buttons to work though. He said he'd have to custom program one which would be pretty costly. So, I've given up on using the factory steering wheel buttons.

A cheap workaround is to use an aftermarket steering wheel control kit. You attach new controls to your steering wheel (either clipped, glued or recessed into new holes drilled into your steering wheel). The controls are powered by a long-life battery. The control unit is paired wirelessly with a receiver which you connect to the your headunit via the KEY1/KEY2 (Pioneer calls them Input 1 and 2), ground and ACC wires. Most headunits have these wires.

This is the option I'm going for. My kit hasn't arrived yet but I'm optimistic it'll work.

FYI, this is the one I bought:

https://www.aliexpress.com/item/4000584816400.html?spm=a2g0s.9042311.0.0.317a4c4dfTx6k3

There are other designs too. Just search the site for "universal steering wheel control radio"

Hope this helps!

[Huawei Watch] mike613ottawa:
I've seen many posts online about the Watch 1 being extra susceptible to screen burn-in. Many people have suggested either keeping ambient mode disabled, or changing watch faces *very* frequently - some suggest daily.

In WatchMaker, there is an option to keep max brightness in dim mode as low as 15%. If this is enabled, with the brightness set to level 1, is there still a possibility of burn-in, or is it really necessary to keep ambient mode off to be safe?

Thanks!!

[General Questions and Answers] nb111:
I have down graded from Android 9 Pie to Android 8 Oreo. However when I try and setup the phone, it searches for software updates and updates it back to Pie again!

Is there anyway to skip the software update search while setting up the phone in Oreo?

(Preferably without needing to root it. I am using a Nokia 8.)
[General Questions and Answers] Droidriven:
Don't sign into the phone, do not connect to a network during setup, just skip all of that to boot into the device without an account and without being connected to a network.

Then go to settings and find the software update center settings, disable it. Then enable mobile data or WiFi, then go to system settings>accounts and add an account, sign into your account and see if it still tries to update.

Hi I have a Galaxy s8plus and its model number is SM-G955w, but I had to flash stock firmware on it and I flashed an American sprint build number and now the phone in the settings reads model number; SM-G055U, I want to root it but don't know how to flash the proper stock Canadian firmware in download mode it reads like this:

CARRIER : XAC

RPMB Fuse Blown

RPMB PROVISIONED

can anyone help me figure out where to get the proper stock firmware for this device and how can I flash a root and twrp recovery?

please and thank you
[Samsung Galaxy S8+ Questions & Answers] Droidriven:
Do a Google search to find the 3 letter code for your region/carrier. Search for:

"Region code for Canada (enter your carrier name here)"

That should find your code.

Then go to Sammobile .com or samsung-updates .com, use the search feature there to enter your model number, this should find a list of firmware for your model number. Then find the newest firmware that matches your 3 letter code for your region/carrier. Download and flash that firmware using Odin.
[LG V20 Questions & Answers] paulmcgranite:
Hey guys, I already tried reddit but I figured I would ask here before I bite the bullet and factory reset my phone.

The problem I keep having is that when I boot my phone, I get to the home screen and immediately get the error "System UI has stopped". The screen then goes black and I can't interact with anything except for my camera and music player using the second screen.

I am not rooted, but I do have USB debugging enabled.

Things I have tried:

1. Rebooting into recovery and wiping cache

-I get to recovery and it gives me "No Command". I have no way to get to the actual recovery to wipe the cache. I have tried holding Vol Up, Vol Down, Power+Up, and Power+Down for 30s ea

2. Reinstalling the SystemUI.apk

-Denied due to no root

3. Restarting the SystemUI.apk

-I can force-stop and enable the com.android.systemui and com.lge.provider.systemui packages, but nothing happens

4. Using adb to perform a full backup so I don't lose any data

-Failed because I can't confirm the backup using my phone. The window to set a password and begin the backup never appears

5. Using Vysor to control my phone from my pc

-It just shows the dead black screen

6. Using the LG Backup tool

-Can't connect, says that I need to enable MTP on the phone

7. Enabling MTP using adb

-Can't figure out how to do this without root and editing files

I feel like I'm all out of options, but I feel like my phone isn't even that ****ed up. I can still use the quick apps and everything loads fine. It's just this System UI that eats ****. Is there a way to reset system apps using adb? I'm really at a loss here but I don't want to give up quite yet.

Thanks

https://rongi.github.io/kotlin-blog/adb/android/2017/06/30/adb-clear-application-cache.html

Or possibly-

ADB command: fastboot erase cache
[LG V20 Questions & Answers] paulmcgranite:
Hi, thanks for the response. I can use all the help I can get.

I tried doing fastboot erase cache, but I get this error:

******** Did you mean to fastboot format this ext4 partition?

Erasing 'cache' FAILED (remote: 'unknown command')

Finished. Total time: 0.043s

I think I ****ed it up by having Secure Start Up enabled.

As for the link, I've tried wiping the cache for both the com.android.systemui and the com.lge.provider.system but neither have done anything after a reboot even though I get a "success" from adb.

I feel like theres gotta be a fix here somewhere, the phone loads everything fine including my icons and then just crashes on that stupid systemui.
[LG V20 Questions & Answers] Mysticblaze347:
..do not format unless you want all gone. If all fails...sadly a factory reset may be in store. I recommend rooting if possible of restore an LG backup if u have one.

[LG V20 Questions & Answers] paulmcgranite:
Yeah, I exhausted my options and I needed my phone to be useable for work, so I bit the bullet and factory reset. I lost some data, but I definitely learned to backup often...
[LG V20 Questions & Answers] paulmcgranite:
Hey thanks for the reply. I ended up factory resetting due to time constraints but to answer your questions:

I was on stock Oreo, unrooted. So realistically there was no way for me to reflash or replace the systemui without root, which would require factory resetting my phone anyway (correct me if I'm wrong).

When I try to start the Tizen Studio Device Manager, it tells me "JAVA_HOME not set in env variables". But my Windows 10 environment variables do have JAVA_HOME set to C:\Program Files\Java\jre1.8.0_201. Anyone know how to get that to work?

Yes, you need to save this as an environment variable. Otherwise Java will not be detected on system.

Simply open properties on Windows and open Env Variable dialog. You should find 2 areas

1. System

2. User

Follow this guide: https://www.hows.tech/2019/03/how-to-set-environment-variables-in-windows-10.html

From command prompt use set or setx commands.

Verify using java -version on command prompt.

Merci. Pardonez-moi, s'il vous plait, mais mon Francais est mal.

I followed the procedure in the tutorial, but had problems. I set the path to C:\Program Files\java\jdk1.8.0_102 as described. I opened a command window and checked echo %JAVA_HOME% and got C:\Program Files\java\jdk-15\jdk1.8.0_102. I presume that I have the wrong version of JAVA in here, but I set the path to C:\Program Files\java\jdk-15 only, and that didn't work either. I rebooted the computer after each trial to see if that would help, but I still couldn't open the Device Manager. The javac -version returned javac 15.

S'il vous plait, aidez moi. Merci beaucoup.

[Nexus 6P Q&A, Help & Troubleshooting] BunnyPig:
Alright, I just got my Nexus 6P up and running again and wanted it to be my secondary phone for work, but now I'm facing an issue I'm not familiar with.

So, the phone works just fine, I have PureNexus 7.1.0 installed on it along with Magisk and I am sure I have TWRP installed on it as well. But I'm not 100% sure.

The issue is that I can't get my phone to boot into bootloader or recovery mode. As soon as I try to enter bootloader or recovery I only get a black screen, nothing else.

To boot back into the phone I have to keep holding my power button down and enter my charging cable or my PC and with some fiddling around it boots just fine into OS.

So, how can I, or, how am I supposed to fix something like this? I can't get adb to work since I can't get into bootloader. Although it still finds my device when I enter the black screen when using adb reboot bootloader command but it won't do anything with the device. So, if I want to install a new recovery it won't do anything, just saying "error: device not found".

Edit: I just want to add that if I do a wipe (factory reset) nothing happens. The device turns off, I insert the charging cable and spam the power button and it just boots like nothing happens, everything remains on the phone.

Just because something is illegal that doesn't mean you can't ask about it. Granted you probably won't get much legit help with it but asking the question is fair game.

There was a changer written by a member to help those who have "legit" use for such a tool. Of course the thread was allowed to live after much Moderator discussion about it but there were heavy warnings abotu the legality of doing such to your phone. Also note that this was back when the Wizard was king so I doubt it will work for newer devices.

2. Your a terrorist :eek:
[Windows Mobile Development and Hacking General] ricky92:
Thanks for the help, is the program iWizard? I found it, and well, it just tells me my IMEI is composed by numbers and

xD

Well, then my question becomes another one: is there a way to downgrade from SPL 2.60 (I think... how do I find it?) to a lower one, just to try if it works?

----------------

@obsydian

No, it's not a stolen phone neither I am a terrorist (what would a terrorist do with a changed IMEI?!? O.o)... It's my father's old phone which he believed it got stolen, so he blocked the IMEI... now that ha has found it again (he left it in our house on the seaside, where I am writing from) he gave it to me because he bought a new one and he doesn't have the bill here, so he can't unlock the IMEI now. I can stil use it as a smartphone and I really like it, but I don't like taking 2 phones with me... so I wanted to fix it, at least temporary (we're going back home in August... -_-"). I don't want to do anything EXTREMELY illegal, just change the IMEI for a few months...
