Hello everyone! I am new here so please bare with me. I am a master auto technician and have installed many older and factory head units but this is my first time installing an Android head unit in my car.

I recently bought a cheap NHOPEEW Android 13 head unit from Amazon and installed it in my 2016 Toyota Camry SE. Everything works however the head unit will not power down with the ignition turned off and the key out. The screen will stay powered on and play music indefinitely until the Yellow B+ wire is disconnected. The red ACC B+ wire seems to have no effect on the head unit.

I pulled the head unit from the car and set it up for bench testing with similar results. The head unit will fully power on with the Yellow wire attached B+. This is odd because it supposed to be for memory functions only as far as I know. The red wire which is supposed to be switched B+ from the ignition switch does nothing. As far as I can tell, the yellow and red wires are installed in the correct pin positions in the connector.

I ended up tearing down the head unit to access the circuit board thinking maybe the B+ and ACC B+ were shorted internally with solder. Everything looks good though. All the soldering looks good, the board looks good and nothing looks or smells burnt.

Something to note: I was able to access the engineer options in the head unit. I was hoping to find some power options. I found a tab labeled power. Under that tab is 3 options, Charge Battery, PMU, and Low Power Protect Debug. I clicked on the PMU tab and it listed out a bunch of stuff I do not understand but did notice everything listed is followed by "ABNORMAL_STATUS_CODE". I'm not sure but I assume instead of this message I should see a 0 or 1. Is this a possible clue as to why the head unit does not power on and off correctly? Under the PMU tab there is also a PMU Register option but I do not know what that is used for.

Has anyone come across an issue like this before?

Do you have any advise on how I could better diagnose what is wrong?

Is thhis most likely a case of defect hardware or could it be as simple as a misconfiguration?

The seller I bought this from is telling me they do not have access to pinouts or schematics which makes this harder to diagnose.

I added pics below. Let me know if there is any other info I should post.

Thanks!

Maybe red and yellow wires from the HU connector are in the wrong position, did you try to swap them off so they work as intended? I had to swap them off on my unit (it was fairly easy to pull them off from the ISO connector with a screwdriver), they were on the wrong position and didn't match my car's connector, so it would always stay powered on.
[Android Head-Units] AnotherPipeDream:
Hi, yup tried that as well but no dice. When connected to my bench power supply I tried it both ways. I also found when attached to just the red wire and ground there is no current draw on that red wire.

EDIT: My reply may not have been clear. I did swap the wires. I connected the red wire to constant B+ and the yellow to switched B+. With the wires swapped and B+ removed from the yellow wire the head unit will shut down but there is no current draw on the red wire at the same time and when reconnecting the yellow wire to B+ the head unit will start from the Android screen and all the settings go back to default once started. In other words nothing in memory has been retained. This leads me to think this is not a wiring issue.
[Android Head-Units] hectus:
Do you have a canbus decoder on? could sound like something is feeding power back

what happens if on the bench u run it on only b+ or b?
[Android Head-Units] AnotherPipeDream:
The head unit came with 2 harnesses. one with extra wiring for the canbus along with a canbus module and a second much simpler harness without canbus. I used the canbus harness in the car but am using the simple harness for the bench testing. I do not see anything that would feed power to an unintended circuit. The red wire connections are good.

Its so strange, it acts like the B+ and ACC circuit are shorted together on the circuit board but they are not.
[Android Head-Units] hectus:
Try this pin in factory setting and see if u find any more options for power and sleep first 8888.

I assume u have checked on ur camry that it actually cuts the power when u turn ignition off?

Normally red wire should be cut when u turn ignition off, yellow goes directly to batter to keep memory and sleep mode etc on.

My next guess would be that its feeding power thru a wrong pin, so double check with a pinout diagram.

I would think its very unlikely that its crossed power somewhere on the mainboards, but u never know, it can be enough with a faulty chip bleeding power thru, so if u get nowhere and u can return the unit for anotherone, even if u end up back in the same place as now, u at least know u aint waisting ur time.

Yes, I have 3 different codes that I have found so far. Each opens different options. The codes are 1234, 5678, and 56789. The last code gives access to the engineer mode. Unfortunately there doesn't seem to be any power options that can be changed other than "PMU Register" but I have no idea what it is or does.

Yes it does and I have also tested the yellow and red wires on the bench with a power supply.

Pin's are correct and just like the pic you attached. I also swapped B+ constant and B+ switched power when I did my bench test to see if the pin's were wrong in the head unit. When it was in the car everything else worked such as speakers, canbus info, illumination, etc. The only fault exhibited was not shutting off with ignition.

Unfortunately I can not return it or exchange it. I review products through an Amazon program which is where I got this head unit and Amazon does not allow warranty replacements or exchanges on the products I review. I do not pay for these items at the time I get them however come tax time the items retail value is considered income that I pay income tax on.

I am fairly confident the problem is on the mainboard. I was hoping maybe someone else has come across a similar issue and might know how to fix it or let me know what to check on the mainboard. If it is something controlled by software, I'm not seeing it.
[Android Head-Units] darkspr1te:
When you use the canbus unit in the car it may be keeping the unit on via canbus (some cars do send on/off via canbus) and this also means the wiring for B+ and switched + maybe provided by the canbus box to the headunit. I have posted a few diagrams of the common ones that do this else where on these forums but if you post pictures of your unit here , i could prob figure out if it is doing it that way.
[Android Head-Units] AnotherPipeDream:
This sounds hopeful, thank you !

I will get some images posted hopefully later tonight. I have some personal stuff going on right now that is pulling my attention away from this for most of the day unfortunately.
[Android Head-Units] AnotherPipeDream:
Here are some pictures of the canbus module, head unit, and connectors.

[Android Head-Units] darkspr1te:
it's this pin out then ,

The one with photo is the CANBOX adapter , the other is the most common connector on toyota to see if you have canbus at the radio it's the 28 pin(without this signal from the car it wont work) this is not the only connector that carries canbus to the headunit (theres about 5 others inc the JDM style)

this link is the pinouts on the radio , you will need to trace the bat+/12V from the radio side to the connector side. on full can control models the B+ comes from the CANBOX unit to the radio only , on semi-control they are both connected to b+.

in the manual listed below is instructions to to change what CANBOX adapter you have and what CAR protocol you are running, I suggest you try this and see which model toyota canbus you have , you may even have to disable CANBOX input as a test or unplug the CANBOX and try.

https://civic.one.pl/odnosniki/dodatki/radio_2DIN/Android_Player_Manual(T10)_EN.pdf

if you have a full Cruise control/menu/dial steering wheel then you will have SW1/2/3 at the radio and AVCLAN +/- as well as canbus.

If you have the volume/answer only but have a rockford fosgate amp and speakers you will have SW1/2/3 and AVCLAN +/- at the radio.

if you have volume/anser only but no amps or branded speakers then you will only see SW1/2/3 at the radio.

if you have plain steering you may see SW1/2/3 factory wires but they will not provide function.

The ones that control power to the radio will be AVCLAN or canbus , these are signals only and the CANBOX unit listens to them and then sends them on in a different format to the headunit , the headunit then will turn off.

This is all controlled via the MCU which actually does the pressing of the SOC buttons and minitoring of REV/ILL signals too and as such it can ignore signals via software.

few things to note,

on the CANBOX the pins marked MCU_RXD/MCU_TXD are 3.3v serial signal and on the head unit they are called canbus( radio connector C , pins 7/8) , they are the same voltage (3.3v) so dont connect the headunits CANBUS pins to the cars canbus, it will damage both.

Pins 11/12 of the CANBOX unit goto the vehicles canbus H/L wires.

[Android Head-Units] darkspr1te:
there is also this method,
[Android Head-Units] AnotherPipeDream:
Thank you for all of this information and the time you have put into it. I am going to really dig into it this weekend.

Question though. The head unit came with two main harnesses. I used the one with the canbus when I installed it in the car but for bench testing I used the smaller harness without the canbus module. Using the harness without the canbus for bench testing I simply removed the terminals from the connector that would normally get plugged in on the car side. This gave me ACC B+, Ground, and Constant B+ to the head unit with no splices in the wires. I used a power supply to test it on the bench with only the main harness power connector plugged into thhe head unit. With the power supply I can set the voltage and when attached to a circuit it will show how many watts and amps a circuit is using. With the power supply connected to the radios ground wire and red wire it shows 0 watts and 0 amps being drawn. I have the head unit main board out at the moment and have verified the integrety of the pins and solder joints on thhe board to be good.

Is using the harness without the canbus basically doing what is seen in the video?

[Android Head-Units] BryanLee01:
Exactly the same thing happens to me as you, with the same radio, were you able to solve the problem?
[Android Head-Units] AnotherPipeDream:
@BryanLee01

Sorry but no I never found a solution despite asking a lot of questions here and other places. It would seem that it is not a common issue. NHOPEEW is peddling some pretty crappy car stereos and are hard to deal with. If it's the same radio as mine, I would try to do a return of the radio to save yourself from a big headache.
[Android Head-Units] BryanLee01:
I was able to solve it, I disconnected the power from the radio harness, and connected it directly to the positive contact of the cigarette case. This way power is only maintained while the vehicle is on. and I have had no problems with memory.
[Android Head-Units] AnotherPipeDream:
Glad you were able to get it sorted. On mine the ACC B+ wire had no effect on the radio. I tried installing just the B+ wire to the cars ACC wire and it would then shut on and off the radio with the ignition but I would have to sit through the whole Android boot up sequence every time I restarted my car.

yes I am but I'm not even using the hot spot I have unlimited mobile data and it's only at 19 gb but once my hot spot reaches 15gb witch is my limit it makes my mobile data unable to load apps I know it shouldn't be connected but when I have the hot spot data reset my mobile data works fine until the hot spot data is back to 15

with the hot spot at 15 I got to be hooked up to WiFi for my apps to load
[General Questions and Answers] tlo0214:
as soon as I paid $5 to add hot spot data my mobile data instantly was able to load anything and I never turned my hot spot on,,, one more thing I noticed is that home depots wifi wouldn't open my casino apps
[General Questions and Answers] EllieCat:
Might just be the store policy.
[General Questions and Answers] tlo0214:
no I was on the phone with support and they think I'm crazy and said that the hot spot data being maxed can't effect the mobile data and has nothing to do with each other

[Touch GSM General] Jamolah:
About a week ago my screen got some weird colors on the right side of my Touch (and I didn't even drop it). I have one more week left on my warranty (talk about lucky).

My question is, if I send it to get it fixed will HTC send me a new phone or will they just fix the screen? And if HTC does fix my phone will they upgrade it to WM6.1?

Oh forgot to ask when I send it in should I remove all apps I put on my phone, so they don't hassle me about it.

Thank you.
[Touch GSM General] xudsa II USERT:
I think they will just fix the screen as the screen is not a software issue. Or unless the OS has a glitch other then that I don't think they will upgrade it for you
[Touch GSM General] Jamolah:
I talked to Rogers, apparently they'll send me a new Touch and I send them back my unit. We'll see...
[Touch GSM General] Imyman:
Its probably dead pixels. It happens sometimes with LCD screens. If they can fix it, they probably will. Though I'm not too sure if you can 'repair' dead pixels. They might replace the LCD or just the entire device. Your probably not going to get WM6.1 on your device since the official release of the HTC touch never came with WM 6.1. That came along for all later versions. If you want WM 6.1, I'd recommend flashing a ROM.
[General Questions and Answers] GreyMako:
Okay so I have a crappy government phone with little storage space so I'm constantly having to cycle in and out the apps I use on a normal basis. But I have ran into an issue that I've never run into before every time I try and install an app my phone or Google Play tells me that I have insufficient space and need to delete apps in order to install the app even though I have double the amount of storage space that the app even required. So I went hunting through the settings and noticed something really strange I've never seen before... Every single one of my system apps is listed at exactly 115 MB. I'm just wondering what the heck is going on with my dang phone it's annoying to not be able to play my game because I can no longer download them

[General Questions and Answers] Droidriven:
When playstore updates your system apps, it installs the updated app in your data partition where your other user apps are installed, it does not install them into system to replace the existing system app that it is updating. You can either delete some of those updated system apps to revert back to their original version that is installed in your system partition or you can push the updated version of those apps to the system partition and overwrite the existing version that is in the system partition. Or you can take a chance on repartitioning your device to make the data partition bigger by taking space from one of your other less important partitions but that is very risky. If your device has an SD card slot, you can try moving your user apps to external SD card or you can try using the external SD card to setup the "Adoptable Storage" feature if your device supports it. This will merge your external SD card with your internal storage and use them both as internal storage.

***NOTE***

If you setup adoptable storage, the device will not boot or function properly if you remove the external sdcard.

Hi all,

I'm contemplating rooting my Realme GT Master Edition to gain more control over my device. However, I'm concerned about the compatibility of banking apps post-rooting. Can anyone confirm if banking apps will still function securely after unlocking the bootloader and rooting? Additionally, if anyone has experience with specific custom ROMs for the Realme GT Master Edition that maintain banking app compatibility while offering root access?
[Realme GT Master Edition] khusika:
Hi @Giogex

For your information that performing UBL and root at this time will affect Play Integrity API checks, which will affect banking applications. In general, the BASIC and DEVICE checks in Play Integrity should be passed. But don't hesitate, you can bypass that check by spoofing your device's fingerprint with the Magisk Module.

Hello!

In my case the banking app still works on Realme GT Master Edition. But when i use it there is a warning message. (ELBA-App)

I use stock rom, unlocked bootloader and did root via magisk.

I think custom roms are not stable enough, when using banking apps it didn't work without much effort (the ones i tried with old devices before - so that is the reason i always stay at stock roms)
[Realme GT Master Edition] mdsiyam:
after rooting if banking app not work just configure the denied list or just use a module to bypass safety net no issue to solve thi. I am using EBL Skybanking, Bkash, Nagad etc from bangladesh without any issue

When you have to flash SEVERAL mods from UNKNOWN developers to eventually make something work, you should understand that you are compromising security. The risk and consequences are 100% your making.
[Realme GT Master Edition] mdsiyam:
my

my apps are working without any other mods i just use magisk denylist feature no other modules and the safetynet bypass module i think it is from trusted source and no potential security risk for that module
[Realme GT Master Edition] mdsiyam:
check the module if you want https://github.com/kdrag0n/safetynet-fix
[Realme GT Master Edition] TheMystic:
1. Popular is not the same as Trusted.

2. Anything that is safe today need not be so tomorrow.

3. App/ mod publishers are unknown and/ or anonymous with unknown intent/ motivation.

There is a reason why banking apps don't want to work when they detect modifications. Unlike game or other app developers, banking apps have purely security reasons to not want to work on modified devices.

By fooling them to work using bypass techniques with the help of random mods, you are banking on the luck factor to be safe. You may not always be lucky.
[Realme GT Master Edition] mdsiyam:
i think you should use your phone as it is right now. bcz any modification in system will result problem in using banking app so dont try to modify system or root just use your system as it is shipped from factory.
[Realme GT Master Edition] TheMystic:
Yes, my phone is 100% stock and it does everything I want from it. Modding a device is more pain than gain today, and I won't mod it with random stuff from random people.

While I appreciate the work that people do to make a lot of things possible, there is a huge element of risk and uncertainty, and it is just not worth it. Especially since stock devices today allow a lot more to be done which were only possible with root until few years back.
