new to 8525, bought off ebay, seems to be a lemon, please advise

First, let me say that I'm definitely a newbie to the 8525, but have spent some time looking over the wiki and searching for answers to my problem, only to come up empty...
I bought an AT&T 8525, with the original WM 5 installed, from eBay. The device has a 14 day warranty and physically appears to be in excellent condition. However, it has two very serious issues that I can't seem to find a simple solution for. Any thoughts, help, etc on the items below would be greatly appreciated!
1. After using the device and turning it off, after it sits for a while it will not power back on. Pressing the power button or none of the other buttons make a difference. The battery is reading fully charged and it still happens when it is plugged into a charger. The only way to make it respond is to perform a soft reset on it. The cycle then just starts over, having reset it about 10 times in a few hours of playing with it.
2. When it reboots, the following appears on the AT&T splash along the bottom:
M 05
S 04
B 06
D 2.15
"No GSM" then appears (I've read about this issue in the wiki just a bit) This occurs with my valid SIM card from another cell phone inserted. When looking at the device info in Settings, the Radio Version label is blank. Upon switching to the hardware tab, the IMEI is also blank.
It just now froze while on, after only performing a soft reset and leaving it with no running items in the background.
Any tips for repairing this, etc appreciated. I really like the form factor of the phone and want to use it, but unfortunately I'm afraid that I'm going to need to send the device back to the seller!
Thanks for taking the time to read this and for any responses.

Sounds like your radio is dead:
http://forum.xda-developers.com/showthread.php?t=349461
Send it back!

What you have is a PDA. NOT a functioning Phone.... With no IMEI your phone function is gone totally. You need to read about any problems the phone has, the seller has to list it legally or will have to refund especially if paid through paypal.
If you do buy a Hermes through ebay, make sure there is no problem with radio or screen\keys. These can be hard to fix and may be a sign of other problems. Also keep a copy of all Emails sent and recieved to\from the seller so you have proof of whats was said. Can only help if the seller decides to be a pain about refunding cash.
Cheers...

I have a bricked 8525 and have those two exact symtoms. If mtty doesn't get it fixed, throw it back to the seller.

Mate, I wouldn't even bother playing with it. If something is different and can be tracked back to you then I can guarantee YOU'LL be blamed for the condition. Send it back for a refund and look for a working Hermes, don't screw around with it or you'll be out of pocket with a virtual paperweight...

[Q] Turn on A501 without using power button

Ok, simple stuff first. Yes it's my first post and yes I have searched the forums relentlessly for a solution. If someone finds another thread, please post a link. Thanks in advance.
I have an Acer Iconia A501 (XE.H6PAN.015 - same as XE.H6PAN.002 in service manual). The power button no longer works. Having done my research, it seems the power switch on the mainboard has come away. Apparently an all too common problem. I have contacted Acer and they want it returned for repair. Fine, BUT they intend to wipe the internal storage.
Is there any way to power the device up without the use of the power button? I don't want to open it as it's still under warranty, hence my problem. And yes, I do keep backups. But there is very important information on the internal storage since the last backup.
Please help. I have obtained service manuals and interface port specs for this model if it helps.
Any positive input appreciated!

Sorry Mate, but without opening the cover, it ain't going to turn on. Even then, you would have to mess around with it, and HOPE it powers up.
Best bet is turn it in for service, and hope they don't decide to update the OS after they fix the PWR button.

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,
Colin

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.

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

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...

US-JY-UL135N2 crashing and won’t recover for hours.

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
Add joy to your car with Joying !

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?

because it will enter the recovery interface . please check whether it can .
Hope your try .
Thanks

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 .
Thanks

How do I make it enter recovery?
-------- Original message --------
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
Dear friend,
Thanks for your well-cooperated with us together .
please noted :
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

Add joy to your car with Joying !
Please have a try . and then feedback us how it going on ?

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?

Search!
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

Witson PX5 RVF 4+64 "alive" just for a few seconds...

Hello ,
I would be very happy if anyone has a solution for my problem. Having spent a long time for search in this forum I even could not get an idea for a solution.
After a good first experience with a WinCE S100 I ordered a Witson PX5 RVF 4+64 for my Opel Astra J via AliExpress.
After the - very probably absolutely correct - installation a start screen was shown very briefly. Then the touch screen stayed black and still is. From Aliexpress I got only confusing information from China. a.) A rar file with an image.rar, which is used to boot from an SD-Mini-Card. b.) Videos showing a completely different approach using DriverAssistant 4.5 and Factory Tool 1.45e.
If I connect the (removed) radio to a 12 Volt laboratory power supply (ignition plus, continuous plus and ground) nothing happens. The fuse in the back is ok. But unit and display unit are dead. Even if I switch on the power with SD-Card (with the rare or the unzipped file) nothing happens. Also, if I copy the rar file to a USB stick and connect it to one of the slots in the back. Nothing flashes, no sound.
Maybe someone has a link or a hint for me where I can start. If all else fails I will send the device back. But I'd like to get it up and running. BTW: The Astra version has no buttons on the display and not even a reset button...
Thanks in advance for any advice.
