I recently dropped my 8525 hard enough to throw battery out of phone. I reinserted battery and started phone. Though I lucked out as everything seemed to work until I couldn't make a call. During boot I get "no GSM" instead of a battery version. I have done a hard reset, but it didn't help. I going to try to install a new ROM and if needed try to flash a new radio.
Anybody else have this problem? I am afraid it is a hardware malfunction in the radio.
If I cannot get this to work (I have already bought a new phone) I will be more then willing to donate (just pay for shipping) the phone to anyone who would like to work on it or test things on it. I have one half good battery and one good battery as well. Like I said everything seems to work but the actual phone. Let me know if you want it.
meh, that is not good news my friend, hope you get it fixed!
if it is a no go however, i wouldn't mind taking it off your hands
best of luck,

Try to reflash original or stock rom. Go with the carrier rom you are supposed to have. It might work as there have been reports to indicate this.
Hope it works for you.
Cheers...
I have recently gone through similar problems, there are numerous things that can cause the NO GSM error on post. So here is the complete solution:
1. Some hard drops can jostle the antenna connection on the board, (a dodgy way of testing if this is the issue is to give the phone a shake and a few soft resets, the NO GSM error will sometimes disappear and state your radio version). There are numerous service manuals that describe how to disassemble and reassemble your handset (read the forums). It sounds scary at first, but so does not having a working phone (be sure you are out of warranty first). You will want to get some electronic circuit board cleaner and give the area around the golden clip on the top left (back facing up) a good spray (while you are at it, why not clean out some dust scroll button detritus). Then dry and reassemble, taking care to force the antenna all the way into the clip.
2. If step one really scares you or you are still in warranty, skip straight to here. A program called mtty (i use vers 1.42 , check the forums) can be used to interrogate the board logic from the bootloader, there are numerous tasks that can be used to clear registers and check gates for errors (for lack of a better word), the wiki has a great entry on all these.
3. A reflash of the radio and maybe even the os isn't a bad idea either... although remember that the latest radio may not be the best for your area/network (READ THE FORUM on this too)
Let us know how you go with it all, and good luck
if you need any further assistance PM me.

This was my idea last night as well. Froze on bootloader. I tried to also Install new radio but also a no-go. I am now downloading a new ROM without radio to see if I can get something other then bootloader. I will keep posted.
I can take the phone apart if I need to, I will make it a last resort. I am not afraid to though as I already have a new phone.
Seeing as I still cannot figure out how to make a ROM to contribute (vista and lack of programing skills) This would be a way I can assist If it would be more useful to someone here not dismantled I would like to look into it.
Update:
The radio hardware must be bad. I cannot flash a new radio or any rom with a radio. Schap's EM6 is working fine. I am going to look into discodergenson 's suggestion of taking the phone apart.
Schematic Diagram
Hi, I have a HTC 8525, with the same problem, doesnt start phone module.. anyway, in my phone, the sim card is not detected. Anybody have schematic diagram for this model? Or any other htc model, for reference.
I think this problem can be caused by dry solder in the driver of sim card, must identify it.
Thanks in advanced
(Sorry for my bad english)

I don't think a bad SIM card connection is a problem. Without a SIM card the phone still needs a radio connection to make 911 calls.
also obviously I only have a t8 and higher, not a t6 which is needed to take phone apart. I will update when I get phone apart.

Guys I have a AL-C0241 and I just installed Malaysk's firmware.
I stupidly did not check my MCU type before hand, thinking that I would keep the existing MCU if I only updated the image.
Everything seemed to install fine, but when I look in the about tablet section, the first few lines are blank, including the MCU
And now I am getting no sound from the radio. Everything else including the wifi and GPS seems to be working OK, but no sound is a problem.
Can anyone tell me the original MCU code of the AL-C0241 ? This is the autopumpkin 7 inch with no buttons on it, just a flat screen.
you can see my entries on the wiki, it's there

So I think mine is bricked now.
After loading Malaysk 3188/1024 firmware I no longer have:
*sound
*gps
*radio
Still working
*wifi
Any idea what I should do to try and fix it? I tried a few things with the reset button but was unable to achieve factory reset. Should I start trying some of the available MCUs?
Ask Pumpkin to send you an image file of your MCU and Firmware. I just send them an email requesting the same for my unit. I told them that I wanted to back it up and can't unless I am rooted.
Let's see what happens.

Worth a try, I will do that.
Would it be possible to get an image of the stock SD card and use that to revert to factory? perhaps nleitao can take a copy of his if he still has access to the insides of his unit?
I'm pretty annoyed with myself, hopefully I don't have to buy another!

I have been exchanging some emails with them, because I was going to do what you did, but only after having the factory image... This is what I got:
Email said:
Hello Nuno,
Thanks for your email.
We attached the user manual for the AL-C0241,please check
And about the newer firmware and mcu, once we get it, we would release it on our official support www.news.autopumpkin.com
Thanks for your patience.
Have a nice day.
Kind regards,

---------- Post added at 12:21 PM ---------- Previous post was at 12:08 PM ----------
Just found a couple of youtube videos, from the official pumpkin channel "pumpkin car stereo support" where they show a software and MCU update for the AL-C0241 !
No download link however! Search AL-C0241 on you tube if interested.
Also checked their blog, no update there
edit: Can't test their firmware because my USBs no longer work, along with most of my hardware.
Its not looking good for me :| Maybe I can find a way to get them working on Malaysk's rom but it's a bit of a catch 22. I can get internet access on the device, however, so all hope is not lost.

I opened my device and that slot is empty. I thought that was for a sim card to enable 3g?
I will put the update.img file on a new sd card and try it tonight, I will post results in approximately 8 hours time

Nop, it's an SD card slot
Sorry guys I have no results as yet, got a bit busy last night
I have to rig up a molex connector so I can power the device up while im inside my house, it should be as simple as connecting the yellow 12v rail and the earth to the harness, so hopefully I will be able to inform you of results before long
Thanks for the support
Fixed!
Thanks for all the help
I used the ROM posted earlier in this thread and the internal SDslot and I eventually got everything working again, I much preferred Malaysk's ROM but couldn't manage to get the MCU updated until after I did the ROM update.
I now have alex v1.1.5 however, I used to have v1.1.7, so that's kinda annoying but I can't see the difference right now anyway. I will write to auto pumpkin and try to get the latest image.
I was also not able to get it to power up using my computer power supply. I connected the 12v to the 12v and the earth to the earth but it wouldn't fire up, super annoying.
Now I am just going to enjoy using it for a while

My apologies to the OP for the kind of hijack but I believe this is the thread with most info for this radio.
I'm having problems with my radio. The screen seems to have a bad contact somewhere, making it complete useless to try to work with it. The odd thing is it never happens in the first 20 minutes ater a cold start. Does someone have an idea what is happening here?

Second problem. I'm completely unable to pair the radio's Bluetooth with whatever devices. I just cant start the pairing process from the radio side.

That screen flicker doesn't look good Is your warranty void due to opening the device? Could be a hardware fault.
As for the bluetooth pairing, I think mine just worked the first time and I haven't looked at it since. I will have another look later and see if mine is doing the same thing

Today I received this answer from them
Support Email said:
Thanks for your feedback.
We're so sorry for the inconvenience and trouble.
1) Firstly sorry for my wrong info about the instruction before,for this new Android product, currently it has no searching function in the built-in Bluetooth. About dropping the built-in Bluetooth app to pair the Bluetooth OBDII with other Bluetooth app, sorry we did not test it before and not sure the operation. However, this product can directly pair the the Wifi OBDII which is tested by us
2) Regarding this issue, frankly we didn't meet it before, if you're good at electronic, it's ok to open the radio by removing screws around the frame then check out the inside connection and we would still promise the warranty.
If we can be of any assistance,please feel free to tell us,thank you!
Best regards,
Colin

So two things I learned. The crappy Bluetooth App can't connect to other devices. The second is I still have warranty after open the cover and check the internal cables.
Yeah, I suspect hardware fault. It only start happening after 20, 25 minutes after power up. something heats up and puff...
well Yeah.. so i bought this stick just now on ebay thinking it should be good enought to give away for streaming some live tv and so on, but
this had obviously the WIFI problem and there i was..
Not beeing able to use WIFI i started to search for different roms and after a couple days constantly searching HOW TO- and downloading different ROMS and watching youtube on how to flash i set up to the task once again..
Beeing able to flash both Nvidia tablets, Samsung Telephones, and Xiaomi i felt confident that i would be able to fix this..
But no, i had a couple different roms that started up With start screen but then that was it, nothing more i couldnt get past start boot logo on either of the 3 roms i thought was correct so i startd to search for same chip roms as this has the 3229 rockchip and the AS something number wifichip..
But then after flashing With a unknown rom it wouldnt start up again or even get recogniced by the computer usb again..
I tried the reset button, i tried shortcutting pin 6-7 and most likely all other as well but no Luck..
There is a blue light but its only halfway as Bright as when the stick was ON and working.
So its like its stuck in some low Power recovery or i dont know..
At least it lights up when i plug it in.
this is the stick With the red "plastic antenna"
Its not an antenne after all by lokking at it but maybe it serves some purpose of making People think its an antenna..
Any suggestions will be apreciated as now i consider it as Waste and after just spending 35 USD on it i would like it to at least get it back so i can sideload some games on it and give it away rather than putting it in the trashcan..
I attach link to the crap i bought so you get the idea of what it is and to also avoid..
Thank you all for all help!!

Hi.
I think I have the same device as you. And also I tried to flash another rom without success, so until I find a good rom, its just a small brick.
I also been in the same situation as you, but you have to short pins 7-8 to revive. Its the pins facing the middle of the device, and counting from the device edge/side.
Good luck. If you find a working rom for it, let me know
No, i have had no luck. Piece of **** device.
Got 80% refund from seller after a couple weeks of complaining.
Just throw it away and buy a ZAPPATI media player or a Nvidia shield if you dont use any 3D.

Hi again.
If you ever revive your dongle, you can get a working rom from the following link:
http://freaktab.com/forum/tv-player-support/rockchip-based-tv-players/rk3229-devices/firmware-roms-tools-bg/623420-mk809iv-rk3229-bricked-how-to-unbrick?p=646882#post646882
It worked for me
Thanks. I will try. Any tips in how to revive it??
I also have an mk809iv. I couldn't get developer options to show after tapping build number but it said "no need you are already a developer" (I assume its preunlocked?) I got bored and decided to flash a rom. I have the rockchip factory tool and rockchip batch tool. I tried flashing an update and the problems began lol
OK..... The stick now doesn't have a blue led on AT All. Tried original mains power source different USB cables different ports on laptop etc.
When I connect it to the TV it doesn't show up on the hdmi. Have I really fried it properly ?
Is there a way to use command on pc or adb shell or something to unlock the bootloader. In batch tool I can see the device after shorting pin 6/7 method but when I load firmware and start to flash then it comes up with failed at boot every time and on different versions of the tool.
I rooted the device before with King root (not king o root) and flashed supersu via rom installer app. Assuming that developer options are open by default, the device should be rooted now...... Right? ?
Anyway is there a way to uninstall all the software and reinstall the manufacturers firmware via the pc ? I have included pics of the board, but when looking at other people's pics the have a lot more chips and nand chips etc mine has one chip on the back and on the other side what I presume to be a heat sync (look like a bit of a tin can
Lol)
I have been on many forums for about 48hrs straight now ? and still can't find answers *sigh*
Recap:- 1 is it fried
2 if not can I sort it via pc
3 HOW?! lol
One last thing, would it run on cyanogenmod 11 ? it's an android device running kit kat and my gingerbread S2 is now on cm11 or are the internal "gibbons" different ?
Many thanks to anyone who can lend me a hand ??
Hi all
the text below is an email exchange between me and joying support. Besides the obvious language barrier I also don't think they are willing or able to do much troubleshooting. I was wondering if anyone here would be kind enough to point me to the right direction.
The problem basically has started after two or three unsuccessful root attempts that most likely left some script that I cannot erase with a factory reset. It could also be one of those very unlucky coincidences where the problem appeared then but rooting was not the cause.
It looks like the unit powers up normally after a period of complete inactivity that has to last at least a few hours and then everything is normal for about one hour. Then it shuts itself off again but will not restart for a few hrs. i didn't get a chance to troubleshoot further and provide detailed timing but I don't think its a heat issue as described elsewhere
After I rooted it successfully I installed the "joying extra tools" but was not really able to use the app.
any help would be appreciated
thanks
Hi I just installed my US-JY-UL135N2 a few weeks ago. It was working fine for a few days but had the same problems described in various posts.
I tried to install superSU in order to install a complete backup application (titanium backup) following the directions from this forum (cant post link yet) first couple of times I was unsuccessful (could not get permission to write the files). After that it started rebooting at random times and sometimes it wont wake up for a few hrs. A couples of days later I rebooted the unit and tried again to root and this it worked. The crashes did not stop so I did a factory reset from the settings menu. When that was completed I looked at the applications and superSU was still there and the crashes continue. I think that maybe some incomplete files have remained when I tried to root the first time. What else can I do? If I did a factory reset shouldn’t it wipe everything? Also should I upgrade from 5.1.1 to 6.0? how? Will that solve the problem?
Do you have support in the USA? Can I talk to someone here?
Dear friend,
Thanks for your email .
Do you mean that the head unit will be crashed after you download the backup application ?
we think that maybe the application is not much more compatible with our head unit .
could you try to directly unload the SuperSu app ? and then check whether it will still crashed ?
and could you show a video to us how it crash ? so that we can know more ?
Hope your positive reply and then we will help you .
Thanks
candy
Thanks
Candy
No I never got a chance to install the application. The unit is now dead it does not start at all so there is noting to show. Is there is a way to make it start? If there is I can uninstall the superSu and let you know if it helped but for now I can't do anything
Dear friend,
Thanks for your reply .
please noted :
You said that you have not installed the application , so how your head unit go dead ? we are a little confusing .
could you please explain what you have done before then the head unit go dead ?
because you also said the Supersu is there , if you have not installed it successfully , bow it will be there .
we hope your kindly reply then we can know that how to help you .
I Said I did not install the backup application (titanium backup) but i did install superSu.
I tried to root the unit but failed a couple of times. The third time I rooted it but then It started random crashes and reboots so I didn't get the chance to install anything else. Can you just tell me if there is a way to restart it or do I have to send it back for warranty repair?
hope you can have a try and feedback us .
Candy

Hi
The unit came back on today by itself after about 15 hours. I uninstalled superSU and reset it again. I don’t know if its going to be stable this time but I will let you know in a few hours
The update you’re suggesting is 6.01 and I read that there is problems with it. Isn’t it better to stay with 5.1.1?
Where can I find the latest file for 5.1.1?

Ok so I left the car off for a few hours and just tried it again. I turned the car on and the unit DID NOT TURN ON AGAIN. It just wakes up whenever it feels like it.
I can’t do anything to it until it turns on again. I there a way to reset it completely?
here is the blog on how to update the android 6.0 : sorry cant post links yet
(please update to 2017-7-7 )
you update the head unit according to the blog , then it will occurred the recovery interface .
Hope you can try .

How do I make it enter recovery?

Ok I just I did the update 2 hrs ago. Then I drove for about 40 minutes and shut off the car. Went back 20 minutes later and tried it and it turned on without problem. I just tried it again now and it won’t turn on. I don’t know what else to do at this point. Is there a way to get logs when it turns back on? It usually turns back on after 6-7 hours

Dear friend,
additional observations/thoughts
I just noticed something else. When I start the car in the morning to go to work the headunit is always on immediately. Does this mean that it stays on after it restarts itself at some point at night ? or does it boot up that fast? (less than a second)? I dont remember ......if this is a heat issue and it started at the same time as when I was trying to root it wouldn't that issue kind of go away when I installed 6.0.1? its supposed to have better cpu management right?

In my opinion it's the heat that's causing the problems combined with with the fact that maybe some of the electronics gave out. It returns back to life when it's cool enough.
Either way make a video demonstrating the issue, complain and demand a new unit under warranty.
In the meantime you can install an app that can monitor the CPU temperatures
Like :
1. https://play.google.com/store/apps/details?id=info.kfsoft.android.MemoryIndicator
2. https://play.google.com/store/apps/details?id=com.yanyan.cputemp
That can display the temperature at all times no matter the app that you are in
Use this app to test the stability and temperature under heavy CPU load : https://play.google.com/store/apps/details?id=com.into.stability
Check the temperature it reaches before blacking out.... it could be the CPU giving out on high temps or maybe something else... just a thought...
Thank you for your reply I will try to work around its schedule and do that. I just went and disconnected the power completely so it stays cool until I'm able to work on your suggestion. Hopefully after work it will start up normally and I can sit there for an hr looking at the temperatures (not happy bout that for a brand new unit) .
the funny thing is that it gives out when the car is off so the unit should be on sleep. How can the temps go up high enough to shut it off when its not even doing anything? The dormancy setting is on so I was assuming it went to sleep.
here is the reply i got from joying below. Basically suggesting to do what I have already done to it
Also some people suggesting sending them a video but a video of what? when its on its running ok when its off its off for hrs and when it comes back its normal again.....it would be a veeeery boring video

Thanks for your well-cooperated with us together .

1) we think that the files on the head unit maybe mess after your root the head unit .
2) So now the head unit can not turn on again , and it may turn back on after 6-7 hours ?
3) if yes , please try to do following processes and check whether will be workable for your problems :
1. Download the update file from window syetem computer, then upzip it and copy the files into
SD card without any folder. Then please insert the SD card into GPS maps card slot.
The files also will be the same updated file :
2. Put ACC wire(red one) and BATT wire(yellow one) together, then connect it to positive power supply 12V;
Put GND wire(black one) to GND.
3. Turn on the head unit,it stuck on JOYING logo, please click "reset"( first time).
4. After the first time reset, the item will restart and it stuck on JOYING logo, please click" reset"(second time)
5. After the second time reset, the item will reboot and it stuck on JOYING logo, please click " reset"(third time)
6. After the third time reset, please don't power off the head unit and wait for a while to update the head unit.
Then watch this video to learn how to update the system: xxxxxxxxxxx
Please check whether it can appear the "Joying logo " and go on the processes we suggested .
Thanks for your time
Candy
Add joy to your car with Joying !
Please have a try . and then feedback us how it going on ?
Thanks

Oh man... you made a big error telling them that you rooted the unit... rooting had nothing to do with the behavior at hand but it's enough to give them something to talk about and delaying to delivering a new unit.
What you should have done before telling them you have a warranty problem.
1. Start the default Joying File Manager go to the internal storage, select all, delete
2. Take out all the SD card and USB sticks and DON'T put them back
3. Reset the unit to defaults, that does not remove root but removes all the apps and settings
4. if the unit is still unstable and it seems related to heat... wait till it cools down
5. prepare a stick with the firmware that you have already on the unit for a reflash
6. flash the unit - now the root is gone - everything is back the way it was when you bought the unit
7. test for stability... if you still have issues that means it's not software it's hardware.... warranty time.
Thanks a lot man!
You have no idea how many times I searched for a way to restore back and wipe all data because I could still see the garbage in there even after a factory reset but couldn't find out how to.
I will follow your steps and then call it a day because it would have to be a heat issue at that point
I ts funny though that it didn't show up prior to root.
On the rooting issue now. I thought they provide a link on "how to root" on their blog....I didn't think I was doing something wrong by just rooting it. I didn't really get a chance to use the root access anyway! You would think they would provide a way to do a full back up in case something went wrong this way we didn't have to resort to rooting
thanks again. I will update the post when I have news
BTW does anyone know what temp the CPU should be running at? or whats the max before it shuts down?

The past weeks have been full of this in 2 threads: the upgrade thrad and the heatsink thread.
And edit, who also answered you in this post, added even more on this in his Q&A thread, which you obviously also missed.
Update .....and some thoughts
@ surfer63. Point taken....I realize I was been lazy. Please accept my sincere apology for taking all the work you guys do for granted.
I don't have much to contribute but here is an update on my issue and also some thoughts on what to do in order to be able to enjoy the best of both worlds _Reliability and function_ in a car radio experience.
BTW. I ripped out my very expensive but very restrictive factory rocford fosgate navigation/camera/Bluetooth/overhead console/back up sensor/ infrared headphone ..blah, blah, blah system in order to install this one, so I had high hopes that I could get this to at least function somewhat reliably but I've been driving for two weeks without a radio or Bluetooth for my phone.
anyway...
Joying USA finally came through with a solution. They offered to send me a 6021 to replace my most likely burned out 5009 unit _new one is on the way_
I had to pay shipping and I was charged $300.00 for the unit but I will be refunded $200.00 when I send the other one back. I'm happy that at least I will have a radio again and have learned my lesson about how real a Chinese warranty is. I hope I wont have any problems getting my $200.00 refund ( I have only used the old radio for about 2 weeks before it burned out)
I chose to "upgrade" to the 6021 _ It would be the same cost for either unit _ because I was told it is more stable after the re-design of the main board and the LCD board. I'm hoping that the overheating issue will be less of a problem with this one although I read reports to the contrary....
I also took surfer63's advise and read up a little and I now know that there is no way to rely on a Chinese android unit to replace a factory head-unit or even a brand name one for that matter because the stability is not there yet (my opinion). We should probably be thankful though that at least Joying and others are not afraid to try and provide this alternative.
I also read up on all the newest high end brand name head-units and nothing has changed since last time I looked. They are all crippled, restrictive and proprietary for the most part when it comes to peripherals. They offer really good sound quality but the ones with the most features also suffer from software and hardware glitches though less frequent than the Chinese ones. The Chinese android units do offer a glimpse into the future but my experience is that they are not at all reliable or fully functional. I believe that in a car environment the most important functions are ease of use, radio reception and phone/Bluetooth quality and reliability (terrestrial radio is still more reliable than internet radio for people that want to listen to the news or traffic updates or local events and such...) . Once that's covered then I guess sound quality, internet connectivity for online content, online navigation and voice commands as well as other similar features become important.
I don't think there is one single head-unit out there that covers all that but maybe not all hope is lost.
My solution is to purchase a single din head-unit with a reliable radio, good sound quality, stellar quality hands-free phone Bluetooth function and maybe USB phone connectivity. I have a spare space in my console so I will install that in there and install the Joying unit _or the next android experiment_on the double din space above. If space is not available on the console one could probably hide it in the glove-box or under the dash.
when the Joying dies again _notice I wrote "when" not if... I can revert back to the simple one until I replace it with the next upgrade or maybe with a tablet. They now make some nice built in mounts for them https://soundmanca.com/
I haven't had time to research the single din unit yet but it most likely will be one of the major brands. maybe this one https://www.amazon.com/Pioneer-DEH-...ud-20&linkId=644693c89a21ea33f675e3023ce5cc4b
I will try to figure out a way to make them both work through the same amplifier and be able to use the hands free function on the single din one, navigation and backup camera on the android and have the choice to play music from either one. I'm not sure how to do that yet but looking into it now. Maybe I can use the Aux input or another "source" input on the single din one which could also be wired to the factory steering wheel controls so that when I answer the phone the AUX switches off and the hands free takes over. I think when the phone call ends it would have to switch back to AUX . I will try to update this post when I figure this out and in the mean time I welcome any thoughts or suggestions
Thank you all for your support
Hello to the community.
I bought this unit 5 days ago, for the simple reason that it was the only unit with 4GB of RAM for under 100 euros! I bought it from banggood using a coupon code I saw in a youtube video.
I haven't installed it in my car yet, I've got it on my desk with power applied and keep playing with it.
I searched many forums to find any information I could about it and ways to improve it, so I decided to start a new thread here and keep all information together.
HARDWARE
7inch LCD, 2 DIN
8core Allwinner T8
4GB RAM
32GB ROM
STM32 MCU
Android 8.1 (NOT 9.0 as falsely stated)
HIDDEN "FACTORY SETTINGS" MENU
Settings - System - About Devices
Alternately tap on the Kernel Version - OS Version (3 times)
Be careful when playing around this engineering menu. Many people, including myself, pressed some button that shouldn't be pressed and ended up with a screen that didn't respond correctly to touches.
If you end up in a similar situation, don't panic and follow this simple procedure:
Connect a USB mouse.
Enter the hidden engineering menu.
Go to the "Other" tab. Find "Touch Learning":
Step1:Screen learning - you adjust the touch ... =>
Step2:Key learning - press "RESET" => touch the "Power" button and select Power at the left short touch = = OK ... then the "Back" button then "Volume +" and "Volume -" => now press "Save & exit" and you're done.
PIN when needed: 666666
The "Developer Options" menu cannot be unlocked like in any other Android device.
In order to have access to this menu, simply install QuickShortcutMaker from the Play Store and find it on the menu. Don't forget to press the little star on the right to move it on Favorites.
I hope there are other users of this unit out there and get this tread going. Next post will be about rooting this device!
Have fun.
ROOTING THE YUEHOO YH-605
DISCLAIMER!!!!!
A. Dealing with firmware modifications and "upgrades", always involves a certain amount of risk bricking your device! DON'T attempt anything if you don't fully understand this and you are not prepared to end up with a "dead" device.
I'm not responsible for anything you try, don't come whining afterwards to me if anything bad happens, you accept full responsibility for your acts.
B. Having said that, I consider this procedure pretty safe. We'll be using the "update procedure" to install new firmware from an SD card. If something goes wrong, you can try to install the original unmodded firmware and go back to a working device.
C. This procedure was executed by me to my own YH-605b, with the following characteristics:
Hardware Information: 8-Core AllWinner - ROM 32GB - DDR3 4GB - 1024x600 - d2
Kernel Version: Linux 4.4.89 - Wed Aug 28 16:11:04 CST 2019
OS Version: KC1D01I1-O49-3.0.4.3.5-IVT-20190828
MCU Version: STM32-20190828-11-KC2-30
If anything is different in yours, please consider if you want to try this, even more
D. I received my unit 5 days ago. I haven't installed it to my car yet. It is sitting on my desk with just power applied to it. This means that no sound, steering wheel controls, or any other car related stuff have been tested. I'm just testing it as an Android device and everything seems to work fine. This also means that the next one who tries the procedure, has to test everything afterwards inside the car and kindly return feedback! I'm not planning in installing this unit in my car any time soon, to tell you the truth I get more pleasure in "playing" with it on my desk, than having it entertaining me in my car Unfortunately, we are living in strange times and right now it helps me kill my time and learn stuff.
E. After the "upgrade", everything will be factory reset. Self-explanatory, just have this in mind, any changes you had made or apps installed will be gone.
F. As far as I can understand, iGO is installed by hand on the device, after manufacturing, during final testing. This means that after the "upgrade", the application will not be there. If you want to keep it, just copy the iGO folder to an SD before the procedure and copy it back and reinstall the application afterwards. As far as I can see, everything else will be there. If something is missing, please report back so everybody will know.
By the way, if anyone could send me the iGO folder, would be nice
G. From my research, people kept telling that the way to do an upgrade is by using the "hidden" internal SD card slot. That's what I used, but by mistake at some point I realized that the external works too! So, you should be able to use the SD card slot on the front face left for the procedure, if this does not work, then be prepared to dismantle the device and use the internal one. Warranty void alert!
PROCEDURE!!!!!
Funny enough, the procedure will be a LOT shorter that the disclaimer! I'll try to keep things as simple as they can be...
1. You will need a microSD card, at least 4GB. Maybe it can work with a USB flash drive, but I didn't have the time to test it.
2. Download the zip file, using the following link.
https://mega.nz/#!YRZl1ADC!JGyl9Occ6CMmxxftkUDOyFxXSn2Fh8kTVI7XLn6qrPY
The file contains the already rooted image of the original firmware, done by me. Also, the PhoenixCard folder which is needed to prepare the SD card, a short video of how to use PhoenixCard (not done by me), and the Magisk Manager application for the device.
3. Extract everything, best to your root directory, e.g. C:\ .
4. Watch the short video. Execute the PhoenixCard application and "burn" the image to the SD card. Give it time, it will seem that it froze but eventually it will finish. Safely unplug the SD card from the computer.
5. Insert the SD card on the device and boot it up. There should be a progress bar if everything is going OK. Wait for it to finish, there should be a brief message like, "CARD OK". The screen then will start to change colors from gray to black and flickering. Don't worry, give it a minute or two and then remove power.
6. Remove the SD card and power it up. If everything went well, it should boot up to factory restored Android. Connect to wifi and enter your Google Play credentials, as usual.
7. Copy from the computer to your SD card, the Magisk Manager apk. Insert the SD card to the device and using ES File Explorer install the application, following the suggested steps.
8. Open Magisk Manager and follow the suggested step. The application should do its magic, reboot and you are done! You've finally got a rooted device
For anyone that tries this, please give feedback, it's essential in order to help others. If anything goes wrong, don't panic and explain what happened, I'll try to help.
If something goes very wrong, try to burn the SD card with the original image provided and "upgrade" it with this.
Original firmware:
https://mega.nz/#!9JYFGYCI!QBHeC1c3sV4Dap0iQlZUyTE8eEld7w86vjmZqwMWeok
If someone is interested in the procedure of patching the original firmware, please tell me and I will prepare a short tutorial.
Have fun
I love this unit!
Hi, by any chance when you "open" the unit did you see anyway to add external mic. Because the one in the screen is very poor quality.... Also tried any car launcher like FCC that works with Bluetooth? It is very hard to find people with technical knowledge on this....

Unfortunately, I reassembled the unit in order not to overheat too much, due to its poor design. I didn't see anything, but perhaps because I wasn't looking for an external mic connector
Maybe you could use an external USB one, just a suggestion.
Also, I didn't have time to play with other car launchers yet, when I do I will report back.
Have fun.
Hello my friend!
First of all my congratulations on the topic, it is the first I see about the YUEHOO YH-605b Head Unit.
I am from Brazil and I acquired this head unit recently, but unfortunately my experience with it was not good. Here are some bugs I found and some things I didn't like:
1. The main screen is horrible, very different from my previous head unit with Android Oreo 8.1, what I liked most about it was that the widgets already appeared on the main screen, on this device the main screen is black and without any widget from apps
2. The music and videos freeze out of nowhere during playback
3. I cannot synchronize my phone's phonebook with the device's phonebook, the message appears synchronizing... remains forever and does not sync any contacts
4. The image on the reverse camera is horrible, the same camera had a very good image on my old head unit.
5. The touch screen is terrible when you touch the corners of the screen.
My question to you would be these:
* Could this root procedure done by you fix some of these bugs?
* Is there a firmware update to fix these problems?
* Can you tell me if is possible to update the operating system of this unit to Android 10 or downgrade to Android 8.1?
I look forward to your responses.
Super
Well have done it and all went very well.
Phoenix Card can be a little flakey but apart from that really reall good.
Thanks a lot been hopeing for this for a while.
I would be intersted in the processe so if you do a little guide that would be super.
And again thanks a million.

Hi,
I also have this headunit, and have noticed it is unstable when trying to run more than 1 app simultaneously eg launch Igo then try to operate a split screen app, it crashes before even selecting another app.
I have checked with some fake memory apps and it appears to only have 2gb memory.
2gb should be sufficient to run simultaneous apps without crashing to launcher, is it possible to fix the incorrect memory amount (and android version) with root?
The launcher also seems to be memory heavy, it appears to take nearly 1gb on its own. I assume all the apps etc on the first page are a part of the launcher, so replacing it may not be possible without loosing functions.
I will upload the igo folder when i get a chance, it's a shade under 8gb so will take me a couple of days!
I'll leave a link when it's done.

Thank you obfripper for your eye-opening message!
I knew that the OS version was spoofed, but I could have never thought that they would spoof the RAM amount too! Silly me.
Unfortunately, you are right. I checked with "Fake Device Test" and your point came true. And for the fact that I was still skeptical, I double checked with a terminal emulator with the "free" command, same result :'(
As for your questions, I searched for restoring the correct amount of RAM in the OS. It's a very difficult procedure, you literally have to recompile the kernel, which is something I don't have the knowledge, neither the time to do. Guess we are stuck with a scam device.
As far the launcher goes. Some apps are indeed dependent on it, some are not. Some people replaced the default apps with others (radio, phone etc) but many of them have issues and don't work, so I'm staying away of trying to replace them. The launcher could be replaced with the stock one with some effort, but although I don't like it being too simple and too "golden", I find it convenient so I decided to keep it.
The only thing I will do is change the "golden" theme which I hate, to a more fancy "green" one. This will happen soon and I will share it when it's done.
I ordered my unit in early March from banggood. I entered their site and opened a complain asking for full refund for being scammed. I'm pretty sure I'll get at least half of my money back and then I will be a little more satisfied with my purchase.
Thank you Dave for all the interesting information and I will keep you updated.
@MarkoDiMarko
Will the device be stable when I install your custom rom. I've also this device and the navigation app keeps closing itself. When the root will fix it I hope I have a stable device. I use TomTom for navigation.

There will be no difference in stability, neither better or worse.
It's the factory ROM, only patched to be rooted with Magisk.
I'm also contacting banggood. It's not working stable with the tomtom navigation app. I think that's becouse the app will use more ram than that's actualy available and then crash.

Hi,
two days ago I received the same radio from banggood. Have you already got any feedback concerning your complain from banggood? Did you get any money back?

I opened up a dispute and they asked for photos and video, showing the problem.
I decided to upload a video on Youtube and send them the link, you can watch it here:
https://www.youtube.com/watch?v=_bRxONGk_BA
Offers, declines and counteroffers started and continued. The biggest amount someone else got back and keep the device, was 40 euros + 2200 BG points. So, that was my last counteroffer to Banggood and that is what I got.
Good luck with the dispute!

After a month struggling with Banggood they refunded me about 35euro. It seems, that through this whole time they have not considered my offers. It was very difficult to negotiate with them, consultant send very similar propositions and information all the time. I also wrote a negative opinion about the product but they did not post it at the auction.
They seems to change cpu in the device...new one purchased on 17/07 has cpu allwinner t3 with max 1200 Mhz same fake 4 Gb memory and fake android....but came with already rooted firmware but not properly working root.
I had the imprudence to buy a radio tape recorder for $ 113 YUEHOO YH-605 on banggood.com.
Everything in it is good according to the description and a video with disassembly and display of components confirms this. Unless the amplifier is soldered from 7388 to 7850.
But in fact it was not what was in the description.
Instead of Android 9 installed 8.1
Allwinner T3L 4 Core 1.2GHz is installed instead of Allwinner T8 8 Core 1.8GHz
Instead of 4GB of RAM, only 2GB is installed. But this is understandable. Allwinner T3L works with no more than 2GB.
bluetooth does not interface with anything other than the phone, you can forget about ELMs and bluetooth adapters for diagnostics of gas equipment (in my case Stag).
Which radio chip is soldered is not clear, the sticker was ripped off by the conspiracy the Chinese and without removing the shielding protection of the soldered one is not possible.
I can't add a photo. I have less than 10 posts. Who disassembled and who has a photo of a sticker with a radio chip designation? I have not yet been able to get the firmware from the seller in order to understand what kind of chip is indicated in it.
"translate by google", sorry.
Seems they brought out a yh-605b version
Ordered mine from banggood (deal price £90 delivered with insurance) from eu warehouse (to the uk)
I ran the fake test device app and although android version is still scammed, they have greatly improved the memory issue! Over 3gb ram (I'll run the test again and update my post with exact figures today).
The manual they provided shows a different stereos wire diagram which is confusing...
Does anyone know if the 8 pin (female on the stereo) is where the steering wheel controls plug into? Im struggling to get it working on a seat altea (factory fitted vw engine) i have the right adaptor so everything else works fine!
Also which igo files are safe to delete or are there any that need to stay? I use google maps and galaxy note 10+ 5g is the no brainer processor to run sat nav ?
Thanks ?

As I can remember hooking it up, you use the "KEY1" cable, plus I used a ground to connect them to the 2 pins that came from my car.
I have already lost the "iGO" folder during update But I remember that there was a folder named "iGO" that contains all the files. If you use a file explorer, I'm pretty sure you will find it and remove it safely.
I have a similar unit I purchased back in March from aliexpress. I stumbled across this post as I'm hoping to find a root solution. Mine passed the android version test on Fake Device Test app even though it's reporting as 9.0 in about device, actual is 8.1, so kinda weird it's reporting correctly everywhere but the about device section. Ram was advertised as 2GB on my device, reported accurately. The sellers page said that if it has 4 cores it is T3 and 8 cores is T8 but everything on mine is reporting as T3-P1, including Fake Device Test app and CPU-Z, even though it does show it indeed has 8 cores. Your devices specs seem to fit closest to my device of any I've seen posted about. My device specs are as follows:
Android Version = 9
Hardware Information = 8 Core Allwinner -ROM 32GB - DDR3 2GB - 1024x600
Kernel Version = Linux 4.9.118 - Wed Oct. 16 13:55:41 CST 2019
OS Version = KC1C01D5-O55-1.0.4.3.1 - BLINK_NETWORK - 20191016
MCU Version = STM32-20190924-11-KC1-38
I figure these units were probably pieced together with spare parts they had a fair amount of. I want to try your root method, but I'm a bit leary of flashing anything to this unit in fear it won't work again. I at least need to make a full back up of each partition before doing much of anything. Due to the minor differences in our Kernel, OS and MCU versions I hesitate to flash the file you provided in Post 2. I learned my lesson a few years ago on an older MTCB unit that I spent two or three days recovering after flashing an incompatible file. Would you be willing to provide the steps taken to achieve root access? Thank you in advance!
