[ONE Q&A, Help & Troubleshooting] Elius2676:
If your car is old enough, a tape deck converter is what you want. If it doesn't have a tape deck, then you want a radio transmitter.

---------- Post added at 08:42 AM ---------- Previous post was at 08:40 AM ----------

And beyond that, if you can modify your car, you can change out the stereo with one that has a 3.5mm audio jack. And furthermore, you can maybe splice in your own 3.5mm jack in the back of your existing stereo.

But these ideas are a bit more invasive.

hello, please help me recover my phone, it's stuck on bootloop after i tried to change brand and model by editing build prop

my phone has lots of important notes , and many open tabs on chrome i don't want to lose track of.

i ve been trying with adb, but i am desperate now, will flashing system.sin delete my data ?
[Xperia Z1 Q&A, Help & Troubleshooting] masterofnocrack:
Did you try to fix the permissions with adb? Do u have a backup
[Xperia Z1 Q&A, Help & Troubleshooting] Gamer4Life:
i have a copy of my build prop, after messing arround and experimenting how to use adb, i think i manage to remove the old file, and pushed the backup, but still my phone keep rebooting after sony logo, i don't get the blue waves
[Xperia Z1 Q&A, Help & Troubleshooting] benplay64:
I don't know how to do it but it must work, you should create a zip file that would inject build.prop. Maybe somebody can help you to do it.
[Xperia Z1 Q&A, Help & Troubleshooting] masterofnocrack:
U need to set the proper permissions.

After pushing ur backup build.prop to /system

Do this in adb shell: chmod 644 /system/build.prop
[Xperia Z1 Q&A, Help & Troubleshooting] lm/\/trix:
if you have TWRP recovery go to mount option and mount system partition.

then go to file manager and find build.prop file in /system then chmod that file.

reboot system.!!!!!

on the other side of the coin you can flash your phone using FLASHTOOL
[Xperia Z1 Q&A, Help & Troubleshooting] DectonX:
flash system.sin using flashtool and exclude userdata from wipe box

if you are on stock try to flash the same build cause as i think every version is do resize partitions so that will make your internal memory not accessible and you will must flash userdata if that happened

and best of all if you have TWRP is to build prerooted firmware and copy to your Internal memory or sdcard and flash it

this will don't do anything with userdata partition
[Xperia Z1 Q&A, Help & Troubleshooting] Gamer4Life:
Thanks everyone, i flashed sin system with flashtool, lost my mods and root, but not big deal my notes are saved.

All this hassle was because i wanted to spoof my phone into galaxy s2 to get old gameloft games to work on my phone. I changed manufacturer ftom sony to Samsung and model number.

Dont know what i did wrong.
[Desire Q&A, Help & Troubleshooting] oscarxp:
Hi Guys

I have a HTC Desire A8181 its about 6 years old, and want to save it, is there any good latest updated Roms i can use as the phone is running on old android version and wanted to be updated to latest version, also whatsapp will no longer work on the phone after this year hence why i need to update it.
[Desire Q&A, Help & Troubleshooting] ze7zez:
Try ROM from spezi77:

LiquidSmooth

or

SlimKat

You will have to accept that the camera is not working and there are slight lag from time to time.

If you really like the HTC Desire, it is minor shortcomings will not be problem for you.

Otherwise, it would be better if you buy something stronger.
[Desire Q&A, Help & Troubleshooting] oscarxp:

when i use the file explorer and go to my windows folder, i cannot delete the cabs for games that i have. i'm guessing there is a way around this, i just don't know it. and do i need these cabs for the games to work? i think it's just the installer for the game, right? it's taking up unnecessary space on my phone. any help is much appreciated.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] last2kn0:
Anything in the windows folder, the OS considers a system file. To delete it you need a 3rd party file explorer like Resco.

[Google Pixel XL Questions & Answers] ukemochi:
So things pretty much went from bad to worse. I downloaded Google's .img file and ran the Universal Android Utility and thought that by running it it would do what it says by putting a fresh image on the phone and relock everything down and I would have to start all over. Nope my phone gave me the middle finger and the Utility turned around and failed 98% on its way through saying you might want to reboot your phone and go back into bootloader mode and try again and that its possible it was the USB. Tried twice, but the 2nd time it left me with a suprise, it rebooted the phone stayed locked on the Google Splash screen forcing me to reboot in to bootloader mode then I noticed it locked the bootloader, and I cannot run the unlock bootloader the classic way or the new VZ one that I used in the first place and when an attempt is made it will say device not found, I am assuming after running the system image from google it turned off USB debugging again. So all my phone can do is go into bootloader mode or if I try to start it up it says "this device is corrupt and cannot be trusted, hit power to to pause boot" and then the phone shuts down. So Flar2 suggested that I create this QA for assistance and said people here would be able to help me out in here. "If you still have the bootloader, you can flash the factory images and it'll be fine". So if anyone can tell me how with instructions on how to specifically flash the factory image and has a link to it I would be most grateful and gladly tip. Google's site explanation on how to do is absolute trash. Its the Verizon Pixel XL
[Google Pixel XL Questions & Answers] razor237:
Im amusing you unlocked your bootloader already

Did you down load the updated tools from here

http://xdaforums.com/showpost.php?p=69239012&postcount=27

And the fresh factory image from

https://developers.google.com/android/images#marlin

I've seen a few people running into trouble flashing the factory image using the wrong ADB/Fastboot tools . I have not flashed the factory image yet so dont know the exact steps. the page with the image files directions say something about a flash-all script, I think you have to put all the file into the directory with the updated tools
[Google Pixel XL Questions & Answers] ukemochi:
[MENTION=4431757]razor237[/MENTION] The bootloader was unlocked but after running the stock google image, the bootloader locked itself and I am confused as how to even flash anything when the bootloader is locked. The I did download from you second link, thats the image that started all this trouble. I keep getting device not found because I know usb debugging isnt turned on and I have no idea how to get around this.
[Google Pixel XL Questions & Answers] razor237:
Thats Odd , so when you boot into the bootloader and read all the text i think is says Device is UNLOCKED does yours say LOCKED?

Do you get the first boot screen saying your device cant be verified press power button to pause boot?

Did you use the other ADB/FastBoot tools ....the minimal tools are not the correct ones for image flash i think
[Google Pixel XL Questions & Answers] ukemochi:
I used the ADB/Fastboot tools you had linked. The bootloader does say LOCKED. If I try to just power on the device it will say "Your device is corrupt. It cant be trusted and may not work properly." So Flar2 said that as long as you can get into fastboot you are fine, but if you try and flash anything at all, everything kicks back saying FAILED because the bootloader is locked. In one way shape or form it says that I need to unlock the OEM. Apparently and I am guessing here, that Devs definitley know a way to push a factory image even when the bootloader is locked, I just dont know how.
[Google Pixel XL Questions & Answers] hutzdani:
So your bootloader is locked , you don't see the little unlock symbol on the Google screen ( or can't you even get this far ? ), if you don't even have an unlocked BL your royally screwed

Seems like your in RMA land now, but more interestingly that whatever ADB tookit you used does not support the new partitions of the new images for pixel this could very well be the root cause of the issue.

Frankly i'd not use any ADB tools to flash an image unless its downloaded via the SDK for that API and device considering this conundrum, but then hindsight is a wonderful thing
[Google Pixel XL Questions & Answers] kiddiosky:
I was able to flash the Stock Image on my Pixel last night "Unlocked International Model"

My steps:

Download and install the Minimal ADB and Fastboot

Download the correct Image file from Google "from link above"

Extract the Image Zip file to my Minimal ADB and Fastboot directory

Put my phone into bootloader mode

Ran the "flash-all" command with Minimal ADB and Fastboot

Took like 5min for it to finish

Pretty weird how yours relocked bootloader. Mine didn't

[MTCD Android Head Units General] AeonSaber:
Hey guys,

Not sure if i'm the first on this forum to receive my joying 8inch head unit but i got it last friday and installed it the same day. This thing is awesome.

I've never had an android head unit but i've been hovering around these forums for about 2 months waiting for a 2gb unit to come out. I got on the new joying unit right when it came out and purchased it on amazon right away. Their customer service was awesome, they made sure i had the tools needed to install it before they shipped it out (which i did). and it still only took 4 days to get to me (central USA).

Coming from a $600 pioneer head unit i could not be happier. This is awesome. If you guys would like some more pics, or information feel free to post here or email me at AeonSaber@gmail.com. Also i am the only one to have a review on amazon so far :cool:

Won't let me put images cause i'm still new to posting.. so here is the URL broken up

imgur .com /a/7vSZX

Installed steering wheel controls. It was not to bad, would of only taken a few minutes if i would of known what to do. I own a Subaru WRX 2010. I had to wire Key 2 to Pin #4 and Pin #14 to ground.
[MTCD Android Head Units General] Grungi:
You will have a car crash soon...

When you keep driving and taking/posting fotos (of your android radio) and fidling arround.

But thanks for the first impression. Looks like they changed the equalizer software from the fake 9 to a honest 3-Band EQ.

Anything about the Audio Quality?

Greetings
[MTCD Android Head Units General] AeonSaber:
Seems good. better then the previous aftermarket radio i had in the car.

Also I did not make the post while driving. :P
[MTCD Android Head Units General] vincel892:
Will you be rooting the device anytime soon? Any bluetooth issues with regards to connecting multiple devices/call quality? any problems with the mic?
[MTCD Android Head Units General] AeonSaber:
Not sure if i need to root it as everything i want i think i can get without. i'm open to hearing arguements about why i should root it though.

I have not tested out multiple devices on the bluetooth, i can do that later today. I have not tested the Mic as i do not make phone calls often. The microphone it came with seems to be almost identical to the one that came with my pioneer, just like a $6 mic you can get on amazon.
[MTCD Android Head Units General] vincel892:
Thanks. If you do end up testing the mic, please let us know!

[MTCD Android Head Units General] wanb1i:
I just installed an 8" in my Prius Plug-in, I couldn't get the steering wheel control and backup camera to work after 2 days of messing with it. So I took it to Best Buy to get that working. Tech support at Joying sucks and it takes 24 hours to get a reply from them.

Bluetooth connects to the phone, but music doesn't play, fm reception sucks, and it won't read my 128gig sdcard. I haven't had a chance to really get into it yet, but I will when I get it back from Best Buy and I'll repost then with a full report.
[MTCD Android Head Units General] AeonSaber:
The FM reception is fine in my car, that is weird that it is not going well for you, maybe you could give the antenna more power. To get the 128gb sd card to work i had to put it in my phone first, my phone formatted it correctly for android, then i threw it into my radio. If you'd like some help with other things i am more than happy if you email me.

Also their customer support has been good to me so far, yes it takes a while for them to reply because their business hours are when we are sleeping. lol
[MTCD Android Head Units General] doitright:
I'm not crazy about the 8"+ units because they look like a tablet duct taped to the dashboard. The DDIN 7" all-glass units are supposed to be available soon. It would be nice if they'd increase the screen size on the DDIN units, there is enough bezel to increase to at LEAST 7.5, maybe even 8". You certainly don't need the row of capacitive buttons on Android, since they're just duplicated from on-screen buttons anyway!

[MTCD Android Head Units General] Zaphod-Beeblebrox:
Is the microphone 'visible' to Android on these? Ie, can you use voice commands ('Ok google'), etc?

I can't believe I'm considering going back down this road, but my Newsmy Android box bit the dust (head unit part is OK), and I don't have the time or energy to really push my DIY project.
[MTCD Android Head Units General] AeonSaber:
I did not get around to trying this out. i did try to pair my ODB adapter and gave up after 5 secconds, was going to google it as this is my first android radio. Did not try out multiple phones. I will try to remember to do the ODB after work today but no promises.
[MTCD Android Head Units General] AeonSaber:
I have not tried it. i'm new to android head units so i do not know where i would start that functionality.
[MTCD Android Head Units General] Zaphod-Beeblebrox:
Quickest thing to do would probably bring up some app (sound recorder?) that can use the MIC and see if it works. Google Maps, Google Search, etc.

I'm not familiar with the MTC series, but almost all of the android head units utilize an 'MCU' (in this case made my microntek) to control the analog audio sources, and mixes in the digital (Android) audio. That analog audio is typically not 'visible' to android (ie, you cannot record FM radio as the Android board only controls the operation of the radio through the MCU. It doesn't actually run that audio through an ADC back to Android.).

In most of the devices I've seen, the MIC port is wired to the Bluetooth HFP module, which is not actually part of the Android board. It's one of those 'analog sources' that the Android box can control through MCU commands, but the underlying I/O is invisible to the system.
[MTCD Android Head Units General] ravits:
How sturdy is it? I have a double din opening that is a little to small and would need to be trimmed to fit. I was thinking since the single din would be completely covered by the larger screen, I wouldn't need to modify the opening. Does it move when using it? I won't be able to stand it if it moves around or makes any rattle sounds. Thanks in advance for your input.
[MTCD Android Head Units General] AeonSaber:
Seems sturdy. the screen mounts on 4 points to the single din, they are fully adjustable. It does not move at all when i touch it.
[MTCD Android Head Units General] Projekt_S13:
Where did you order your unit from? Amazon or directly from Joying? I would rather order through amazon for the better customer service but if they aren't shipping until the end of nov/beginning of dec I would order through Joying to receive it sooner.
[MTCD Android Head Units General] Orisai:
Actually, it's better to have them off the screen, as they take too much valuable screen space and can't be aligned vertically.

I have the 7in 2gb version installed in my car. I can't get OBDII devices to connect to bluetooth as well. Connects to my phone, but not with a basic ELM327 or my OBDLINK MX device. I've tried "0000" and "1234" passwords on both. None connect.

Bluetooth problems

I agree, I just got a JY-UL135N2 which is the new 7" with hard buttons down the left side volume knob at the top. It is one of the new 2Gig RAM, 32Gig FLASH units using the Intel SOPHIA chipset. The unit paired with my phone trouble free but I have had no luck with pairing to other devices. I tried multiple ELM-327 modules that I know work with my tablet. The Joying unit could see the devices, but wouldn't pair with any of them. Tried a keyboard and headphones with same result. It did pair to a tablet, but did so using the phone profile.

I also, noticed that as soon as you ask the unit to attempt to pair to anything it immediately breaks the link to the phone, the only successful link it appears to make.

AceEngineer :cool:

---------- Post added at 06:31 PM ---------- Previous post was at 06:19 PM ----------

I sent the following to

Joying Support

and they answered as follows:

"I recently bought a JY-UL135N2 unit and am having trouble getting your Bluetooth implementation to work with Bluetooth devices other than my phone. My phone pairs with the head unit automatically after setup just as it should, but I cannot get the unit to pair with any other Bluetooth device. I have tried several different ELM-377 modules, headphones, a Bluetooth keyboard and a tablet, all devices known to function correctly. The Joying unit saw every one of them but refused to pair with any of them. For some it asked for a password and then stalled and some stalled immediately upon asking it to attempt a link. Another anomaly is the fact that as soon as I ask the Joying unit to attempt a link with any device, it immediately drops the link to my phone. Surely the unit is not limited to a single Bluetooth device at a time? I have tried all the methods shown in the videos on the your blog and repeated everything with my phone powered off, all to no avail. Please help me with this very basic apparent flaw because it very severely restricts use of your device."

They answered:

"Nice day

Our head unit can only support to connect the mobile phone by Bluetooth, and connect our OBD2

Can not support to connect other Bluetooth device

Hope you do not mind

Mandy"

So you see until Joying comes out with a firmware update there is no Bluetooth beyond OBDII or your phone and not both at the same time it seems. So you don't really have a fully functioning Android device, but rather a fancy car stereo.

AceEngineer :cool:

FRAUD! Typical Chinese JUNK!

I'm so pissed! I bought the 8" single din & after 10 days & over $500 trying to get it to work as expected, I finally got the steering wheel control to work on my Prius Plug-in! What a efing hassle!

I'm also not sure sure it's really Android 5.1.1. I tried to use Nova Launcher, but it won't allow any widget to be on the screen! WTF!

I'm really very disappointed with this product! Just CHINESE JUNK! Aa $800 mistake! Live & learn!
[MTCD Android Head Units General] AeonSaber:
I didn't see your question until now. I ordered from amazon. Amazon said late november/december delivery but it came in about 4 days.
[MTCD Android Head Units General] AeonSaber:
Alright so weird thing. Apparently android head units cannot read bluetooth OBD dongles that are not named OBD or OBDII. You could fight with them to make it work over a firmware update but instead i bought the OBDLINK SX. which is USB and is faster than the MX and the LX. (i had the LX before). the SX is not very expensive and works great.

SX PID/s = 160ish

my LX had about 150 PID/s

Sorry about the slow replies guys. i guess i didn't see the emails from XDA.
[MTCD Android Head Units General] AeonSaber:
That sucks. It took me quite a while to figure out my steering wheel controls. Nobody on the internet has documented what needs to be done in my car for an android radio. So i had to figure it out. without prior knowledge of radio installs i don't know if i would of ever got it.
[MTCD Android Head Units General] wanb1i:
How can a company expect people to install this thing without instructions? After asking for a week, they finally supplied the directions! It also helped that I asked the Toyota dealer for a schematic so I knew which wire too attach to key 1 & 2! Miraculously they showed up in the program screen! Imagine that!?
[MTCD Android Head Units General] AeonSaber:
It's pretty self explanatory. I didn't need instruction for the radio install it self, it's like installing any other radio. It is understandable that they do not have SWC install instructions for every model. I think most people who have never installed an aftermarket radio before buy a non-chinese one. so they have not had very many issues with people needing help.
