Carpad 3 NR900 bricked, how can i fix?

Hello guys i need help with my unit, i briked the machine and i now dont know how to fix it. I get a white screen on power on and thats it.
I began installing app with root privileges but one night my volume did not work, i decided to flash a mcu update from the wiki page. I flashed using flashify due to me being unable to get custom recovery set up. Now my android unit has a white screen.
I went on on buying the pumpkin brand to give it a try, i was so disappointed with it that i regret messing with my newsmy. Please if anyone can help me fix my newsmy unit.

Flashify is for updating the Android system, it can't flash the MCU.
Did you flash the MCU (using "update setting" app) or did you flash a new Android firmware?

I flashed a MCU that was posted on the newsmy xda developers page using flashifi, the only thing I could think off is that it was not for the carpad 3 but for the 2. I wouldn't even know where to find the original since I did not do a back up.
every day I beat my self in the head for messing with it and spending money on a pumpkin instead of another newsmy.

The Newsmy Carpad II and III MCU images are the same. You aren't supposed to flash the MCU with anything other than the built in "Update Settings" tool. That's probably where you went wrong. I don't think what you did will be recoverable.

You should still be able to recover this (hopefully) through batchtool. You've likely not messed up the MCU firmware itself, but rather the android image. Batchtool should be able to fix this.
You will, however, need to set up a way to provide 12V power to the device, and connect to a computer (installing the right drivers is a bit tricky, etc).

Did you try to connect OTA port to Computer? White screen - that mean you are in bootloader mode. Install rockchip driver and then you can flash firmware as normal with RKbatools. I do it many time.
Do it your self exacctly follow there steps:
1 - Install rockchip driver on computer. (Windows 7 32 bit or you can't install succesful).
2 - Connect HU to PC via USB OTA cable (male to male). The cable need to be shortest, 10 - 15 cm or shorter. I have tried with long cable and didn't succes (need connect to PC before connect power).

3 - Connect the Power to HU (do it at home, dont do it on the car, because we need the power disconnect, on the car only acc cutoff - with acc off we cant do anything with RKbattool). After connect to power, the HU will start, at this time press 5 points on screen. if you do right way, then HU will boot to bootloader mode (white screen with dark row on top screen).
4 - Use RKbatool to restore firmware and your HU will be live as the firts time, when it come to you.
Try it and if it's too hard for you to do. PLz send me message, i can make video to help you. but I hope you dont need that .

thank you will be giving it a try once I get out of work. I just need to find a way to feed power to the HU, I will keep you updated.

Wellcome home!
You can try this 1.4.2 firmware, which was cooked by me.
I did preroot with SuperSU
I installed Framwork and install addtions for multi funtion SWC. One button on SWC can do 6 function
Carpad III is the best head unit, which i have ever use

[How To] Update you QuadCore R16 Tonghai AllWinner TopWay Eincar from 4.4/5.1 to 6.0

Hi guys. as promised, i decided to make an how to, so you can update your headunits, commonly known as QuadCore R16, to android Marshmallow. First i wanna thank @dickjones for all is help in 4pda forum
Files Needed - Android 6.0 Image and software to update - https://yadi.sk/d/CEZ8Rwe_3KbMbj
Recovery in Case of first attempt Bootloop - https://yadi.sk/d/1krDlyPP3JXFaD
Final FW recomended with root included - https://yadi.sk/d/suOSRwtd3KSbw4
Apk to put the unit in flash state - http://www9.zippyshare.com/v/ujNIf42V/file.html
Hardware Needed - Male to Male USB. i made mine from two old usb cables. just cut them and join black with black, red with red, white with white and green with green. Isolate so they wont touch each other.
I advise to this with the unit next to the PC. For this, use a PC power suply, cut two yellows and join them with the red and the yellow from the Unit. Then cut two blacks from the PSU and join them with the black from the Unit. After this, find the green wire of the PSU, cut it and join it with another black from the PSU. this will make that when you turn on the PSU, it will start without an assist from a PC.
Last before you start, in the ANDROID 6 files you will download there is a video of the process, but you dont need to follow any step till step 10, due to the PCUpdate.apk, that allows you to put your unit in flash state withou the need of dismantling the unit.
1- Install Phoenix Suit. Also install the Google USB Driver provided with phoenixsuit installation. if it gives an error on the driver instalation, continue with the instalation and download the google driver usb from any site. Copy all the driver files and paste them in the AllWinnerTech Driver folder. Install Phoenix Suit again, and at the driver instalation you'll notice that there is no error anymore.
2-After instalaltion finished, open phoensuit, press the Ancor Icon, second from the left, then blue box and select the image provided with Android6.rar, named sun8iw5p1_android_d7_uart0
3-Now in your headunit install PCUpdate.apk and open it. Proceed with flashstate. Unit will turn dark. Its now in flashstate. Now connect your USB Male to Male from your PC to the usb from the unit. If you have two usb cables in the unit, if pc doesnt detect on the first one, change to second cable. Only one will work for flash purposes.
4-As soon as the pc detects the unit, if some driver begin to install, let it finish, and then, on the PhoenixSuit, press the GREEN BOX in the Ancor Menu. Unit will start to update. Let it finish.
5-Unit will reboot after finish
6-The first boot may take a few minutes. If it boots fine, Proceed to step
7-This part is for units that got in bootlop after phoenixsuit flashing. you will flash the recovery in case of bootloop provided above. USB PEN Fat32, put the file in the root of the usb. This part may differ from unit to unit. On the ones with hardware buttons, the force flash state is turning off the unit, insert usb with the recovery file, press home button and let it pressed, turn on the unit and as soon as it turns on, press once the reset button. let the home button pressed till flash screen appears. let it finish. Again, if it dosent detect the file, repeat the process but in the second usb cable from the unit.
8-after finish, unit will enter recovery. insert a usb keyboard in the unit to navigate recovery. factory reset and the wipe cache. when its done turn off the headunit and emove usb.
9-download the Final Firmware provided above and put it on the root of the formated fat32 usb.
10-insert the usb in usb cable from headunit, force flash the FW again like you did in step 7. Unit will flash the final firmware, takes about 2 minutes to boot.
VOILA, you are in 6.0
Im not responsable for broken devices. do this at you own risk.
This was tested in two units, one from eincar with fake 5.1 and in another with already two years bought in aliexpress. one said astar y3 cortex a7, other astar d3 cortex a9. both are working perfect with android 6.0

HI, thank you for the detailed process. May i ask for the reason behind flashing sun8iw5p1_android_d7_uart0 prior to the final firmeware

Thats because you need to use phoenixsuit to upgrade the unit first, and that file is the one phoenixsuit will accept. If you try to flash the final firmware first, the unit simply wont flash the fw

I have a problem, te app that put my android in flash state puts it with black screen and horizontal green lines, after that, my unit its connected and just after that the unit reboots and it says windows doesnt recognice it.
can anyone help me? Thank you!
It looks like that app doesnt put the radio in flash state

Thanks for the guide. Has this been tested with a unit that has been flashed with the re-partitioned 7.2GB internal memory from IQ Navi? Don't want to lose the space and revert back to the 1.5GB from before.

sounds like you dont have google usb driver instaled properly. you have to download google usb driver manually, take all the files from the driver, copy them to the driver folder of phoenixsuit and reinstall the phoenixsuit

I have this problem and I have not found a solution ...

This issue sounds like one of two things:
First, its possible that your usb card is damaged.
Second, Its much more likely that the issue is with PC that you are connecting to or the USB cord.
The PC obstructions can be resolved by following steps outlined in several extensive posts that I made on these types of issues in this forum: https://forum.xda-developers.com/le-pro3/how-to/guide-unbrick-le-pro3-tested-t3622340 I did alot of research to help a couple of friends successfully unbrick their phone, and created several sets of unbricking steps, in addition to the OP. Everything that I know on how to resolve a bricked phone is covered.
Does the phone charge? If so its mostly likely not the card. if its charging you will see a blinking red light. If you do not see the red blinking light leave it on the charger for 24 hours and recheck.
Quite a few people have unbricked their phones using these steps. Go to search box within the forum and search my name I posted updated links for every file and provided an abundance of steps to try to resolve your issue. Read through the forum many people provided alot of great information. Its long, but worth fixing your phone.

But I can't find nothing for recognize this Fone.
I have other LE PRO 3 and use it for test all connections mode.
I use generic drivers of windows and the drivers of qualcomm. I try select and install by the list on windows. But all options not working.
One time trying I select and install the qualcomm driver manually the device show in the device list on windows and I configure the port to show in flash one in QFIL mode and try flash some times. But when disconnect the phone it show in the list permanently connected or not. When I try open it in flash one I need change the COM to show again in flash one but not really connect.
I turn on the Fone in all mode recovery, fastboot and system.
TWRP work fine but is a old version and not work OTG all other functions work fine.
FASTBOOT I can enter normally but I can connect to pc.
System only stop in the leEco logo.
QFIL mode I can entre by +-power and I have a deep flash cable.
I'm newbie and this is a fist bricked phone in my hands is my learning experience.
If you have any ideas for helping me.
Thanks for the attention.

Your phone is not bricked. ( It it was you would not be able to access Fast boot or recovery)
When you connect the OTG drive, Don't forget to click install and then select the drive.
If it does not see it reformat the flash drive on your desktop computer to Fat 32 add your Rom, Gapps and magisk.
If it still does not see it try another flash drive or use the All in One tool.
TOOL ALL IN ONE
If your device not recognized is a usb driver issue, and You will need to reinstall the Google USB driver, and while you are at it check to make sure adb is up to date.
Easy Way to do this with one tool
@mauronofrio built an excellent tool for keeping your drivers and adb up to date. Plus it will give ADB system wide privileges.
Mauronofrio's tool is called: "TOOL ALL IN ONE"" and it's great,
After you install it, make sure to check for updates.
Get it here:*https://toolaio.tk**
XDA Main Page:*https://forum.xda-developers.com/le-pro3/development/tool-tool-one-mauronofrio-t3580611
* The all is one tool is excellent and you can use it to install everything you want.
* You can use it to unlock the bootloader.
* Install TWRP,
* Fast your Rom, Gapps and Magisk etc.
* The tool will also update your existing installation of ADB, Android Drivers, and provide system wide ADB privileges.
Since you are having issues I would recommend that you flash lineage 15.1 - It is highly stable and is Caf based.
Make sure that you are using a current version of TWRP and you are rooted. be in the habit of alway rebooting to recovery before rebooting to system. Make sure TWRP stay installed overtime you flash a Rom by checking boxes to check for TWRP install. Otherwise you will be bricked.
This issue sound like you are just boot-looping or you have a soft brick .
You should first try to do a factory reset from the Wipe menu. Then if you can get the OTG drive working, use the all in one tool, or just send the files to the phones storage using Windows explorer.
If you end up with a encrypted storage issue
To format the storage*
Go to Wipe, choose Format Data and follow the instructions.*
This will erase all of photos , music, etc
If you wiped your data partition, you'll need to push the zip file to the newly formatted storage. -*This is one BIG reason why using OTG is better.*You can use Mauronofrio's "TOOL ALL IN ONE"" for pushing the ROM, Gapps, and Magisk to storage.
Root: You absolutely should root!
You will need to wipe storage>Advanced wipe select everything except for your usb drive ( Note this will erase your storage and any files you have on storage)
Reboot to recovery > Install> RoM, Gapps, Magisk > reboot to recovery> reboot to system
If you still have issues, let me know. I am certain that you do not have a brick, it is possible that you USB card in the phone is going bad. but I doubt it.
Finally, get rid of the factory usb cable and replace it with a high quality cable. The stock cable has been known to fry the usb card. and some people go ahead and replace the cable and charger altogether.
I would recommend Anker or this one by google: https://www.amazon.com/Google-Origi...8064&sr=1-22&keywords=USB+Type+C+Wall+Charger

LG G2 D802 No Root BootLoop Issue

Hi,
I had my LG G2 for a couple of years now, but I have always kept it with the original Android that it came with. This means that I have not installed a recovery or rooted the device.
But today, while browsing my phone (in Chrome more exactly) the phone froze and rebooted. Since then it never made it past the logo. Cheking on the internet I found that I have a bootloop, but all the guides and posts involve peoples with Recovery and Root, which isn't the case for me.
Because I have important personal data on the phone, I decided to try and find a way to backup the data before attempting either to install the stock rom or a hard reset. I have started and installed the following software:
1) LGMobileDriver_WHQL_Ver_4.2.0 -> downloaded from LG site
2) LGMobileSupportTool -> downloaded from LG site
3) LGPCSuite_Setup -> downloaded from LG site
4) LGBridge_Setup -> downloaded from LG site
5) UniversalAdbDriverSetup -> KOUSH ADB driver
When entering the device in "Download" mode connected to my pc, Windows attempts to install the following drivers:
1. USB Composite
2. LGE Andoid USB Serial Port
2. CDC Serial / LGE AndroidNet USB Modem
But even with all the above software installed, my Windows 7 x64 can't successfully install all the drivers when attempting to recognize the device.

As a concequnce of this, none of LG software recognizes the phone. I was really confident in LGBridge since I saw that it had a "Backup Device" option.
Is there a way to back up the device (in full if needed)? I don't remember if I have ever connected the device to my pc and enabled USB Debugging in it, but most probably I didn't - but none the less I would try anything in order to recover my data.

[Update]
I have tried installing any ADB driver possible (from Intel, Google, universal, quick one - adb-setup-1.4.3) but neither ADB nor fastboot recognizes the device when it is in Update mode, Hard reset mode, or just powering the device.
Since this didn't worked and had a ton of different drivers, I have unistalled all and every LG application, and in order to follow this guide https://forum.xda-developers.com/showthread.php?t=2432476 I have installed only LG-Mobile-Driver_v3.14.1 and connected my phone in Update mode. I have received the same message from above about Windows install drivers but in device manager I don't have anything with an exclamation mark:
Now I want to follow the above guide and use the normal flash option in order to keep all my data. But here I have encountered another issue: i am not sure which version my phone had. Is there an option to get this information in Download mode? For this I have tryied connecting with ADB, but as already mentioned this didn't work at all. Using my information from the LG G2 box I have 6RO and according to this the version should be D80230D_00 (I haven't found one for my country - Romania - but I guess any should do, right?). But the complicated part is that according to LG Mobile Support Tool that seems to recognize somewhat the device (I am not so sure about this one) the version is different: D80210E.
I want to mention that I had the stock firmware the phone came with and purchase it in Romania (on the box it says: "This equipment may be operated in all European countries") and never did any update (OTA or otherwise) and kept like it came. I am also certain that the android version was KitKat (4.4 – 4.4.4 but not sure which one exactly) because I wasn't able to install applications that requried Lollipop (5.0 – 5.1.1)
Do you have any recommendations about which one I should use?
I want to thank you in advance for all the help.
[Update2]
After reading some more forum posts it looks like my phone was rooted because in download mode there is ROOTED written in RED in the bottom. But I have never rooted the phone. Maybe this might help me in some way.

Hi,
I had my LG G2 for a couple of years now, but I have always kept it with the original Android that it came with. This means that I have not installed a recovery or rooted the device.
But today, while browsing my phone (in Chrome more exactly) the phone froze and rebooted. Since then it never made it past the logo. Cheking on the internet I found that I have a bootloop, but all the guides and posts involve peoples with Recovery and Root, which isn't the case for me.
Because I have important personal data on the phone, I decided to try and find a way to backup the data before attempting either to install the stock rom or a hard reset. I have started and installed the following software:
1) LGMobileDriver_WHQL_Ver_4.2.0 -> downloaded from LG site
2) LGMobileSupportTool -> downloaded from LG site
3) LGPCSuite_Setup -> downloaded from LG site
4) LGBridge_Setup -> downloaded from LG site
5) UniversalAdbDriverSetup -> KOUSH ADB driver
When entering the device in "Download" mode connected to my pc, Windows attempts to install the following drivers:
1. USB Composite
2. LGE Andoid USB Serial Port
2. CDC Serial / LGE AndroidNet USB Modem
But even with all the above software installed, my Windows 7 x64 can't successfully install all the drivers when attempting to recognize the device.
As a concequnce of this, none of LG software recognizes the phone. I was really confident in LGBridge since I saw that it had a "Backup Device" option.
Is there a way to back up the device (in full if needed)? I don't remember if I have ever connected the device to my pc and enabled USB Debugging in it, but most probably I didn't - but none the less I would try anything in order to recover my data.
I really appreaciate any help.

[Update3]
I have found the tool LGUP and according to this one the version is as well D80210E because it recognizes the device in Download Mode and on COM4.
Now I am not sure if I should use this tool to flash the same version [D80210E] or use the LG Flash Tool with normal flash option in order to keep all the data.
If someone has any ideas, please let me know.
I appreciate any help.

Short update: I have sent the device to a local service center, but after almost 2 weeks they said me that they are unable to fix the phone without erasing the data and they can't recover the data from the phone. So I have declined that offer being prepared to test everything I found on the net.
Back home, I tested the most non-intrusive method: the freezer. First time I have left the phone in the freezer for 30 minutes and voila the phone booted up in Android. Unfortunately it hold only for 15 minutes and then it restarted itself again. Then I left it in rice for about 30 minutes and then put in the freezer again for 30 minutes, and this time the phone remained on for 2h and was able to back-up everything (even copying all folders from internal storage).
Since the phone is still on even now, I am a little baffled. What I have noticed different from the first time is that the first time I have activated Wifi in order to sync with Google. The second time the WiFi wouldn't even activate, disregarding how many time I would attempt to enable it. It finally connected by itself after ~1h. I am not sure what exactly is the issue and I am looking for a new phone.
What I can say for other people having the same issue is to first try the freezer quick fix. And don't forget the rice, since there will be some sweat on the phone after pulling it out from the freezer.

Help!! I accidentally soft-bricked (or hard-bricked) my PX6 Rk3399 Android 10 HU!

First of all, thank you so much all for any help!! It's my first time posting in the forum which I think speaks to my desperation state right now:crying:, so anything is greatly appreciated!
I bought an Android 10 unit with the PX6 Rk3399 processor, but it had some bloatware that I wanted to get rid of (mainly a knock-off android auto that started when I plugged my phone in even after disabling the app and it got pretty annoying). I decided to root the unit, but it wouldn't stay rooted after restart. I then decided to let SuperSU update the SU binaries despite knowing that something could go wrong, and of course the unit went straight into bootloop!
I then accessed Recovery mode by long pressing the power button (waiting for the unit to flash 5 times) then releasing and pressing again (don't ask me how I found this out). It had an option to flash updates, so I tried flashing the Kal9k Android 9 ROM, with no luck (kept getting error 1001). Then I found a firmware in update.zip form for a similar radio, with my processor and ram and etc from sygav, so I decided to flash that one using the update option on recovery. No luck though, as it was still stuck on boolook with a ford logo (as if the original system partition wasn't flashed and was still there). I couldn't access adb from recovery to see if I could delete the SU folder (if I plugged a USB cable on recovery, the computer didn't seem to see anything), so I booted into bootloader from recovery. Which by the way, was a black screen but did get picked up through USB by windows.
After tinkering with drivers for hours, I don't know how, but my unit got connected and recognized by fastboot. But in trying to erase the system partition, there was no way for system to be found. Every other partition (i.e. cache) could be erased but not system. I also couldn't flash the firmware I found because it being an update.zip, it didn't have a system.img (but it did have an image for everything else, such as boot, recovery, etc).
So I decided to flash a firmware from a guy on the internet that had a soft brick, and I flashall'd it. Now I'm starting to think this guy's firmware was for another completely different system (oh and by the way, System.img failed to flash as it couldn't find the partition, but it really was the only firmware I could find that had a system.img, so since I was completely desperate I stupidly went for it).
Now I can no longer boot into recovery, and I might be booting straight into bootloader mode, but I am not that sure. After I do the trick with the lights flashing and all, the device gets picked up by my computer, but as an unknown device:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I manually update it's drivers with the downloaded bootloader drivers from the android sdk (google USB drivers) and it gets detected as a Kedacom USB device, not an Android Device, so no fastboot:
Then if I disconnect it and connect it again, it shows up as an unrecognizable USB device or something like that.
It seems like the same problem I had when I first connected to bootloader, but I don't even know what I did to fix that . I think I might have rebooted into recovery, and then from there booted into bootloader, and somehow my computer then had Android drivers available for install and I manually installed them and it worked? Maybe? I really have no idea, but I can't try that because I can't get to recovery.
I have an update.zip with what I think is the closest firmware to what my radio had originally, an Android 10 PX6 firmware, from which I was planning to install the boot, bootloader and recovery if I had access to fastboot (which I really don't know how to make windows see that it might be a bootloader device), however, since I don't have a system.img to flash and bootloader doesn't even find the system partition, I don't even know where I would go from there.
What do you guys think I should do? What are my options? Did I just hard brick my unit? I wouldn't think so because windows detects "something" even if it can't assign it the driver. But if it is hard bricked, I am not scared to open it up and to do whatever I have to do, if just am really unsure on what to do and how to do it!
Again, any help is highly appreciated! And thank you so much in advance!:fingers-crossed:
SOLUTION:
Alright, this was a ride! It took me about two weeks to find the solution. No matter what I flashed from the recovery, the unit would still be on bootloop, but the last thing I flashed was an update.zip I found on the internet from some guy, and that made my unit completely hard bricked and irrecoverable (no access to recovery). So here's what I did.
Apparently, reading around Rocketchips (PX3,PX5,PX6) have like a "if everything else fails" kind of mode, for stupid people like me, called MASKROM Mode. It's the last resort mode that lets you flash something on the unit when everything fails. That mode is not flashable (you can't mess it up). It's kind of like if a computer had an integrated last resort in case you mess up and break the BIOS.
To get to it though, it is kind of complicated. You need to get to the PX6/5/3 board, which is basically the heart of your radio. So start unscrewing!
The board will look something like this one:
https://sc01.alicdn.com/kf/HTB1f6tCE.R1BeNjy0Fmq6z0wVXaC.jpg
Where the top part is a heatsink that you might also have to remove. PX5s and PX3s may not look exactly like so, but look for something of more or less the same characteristics and form factor, you'll know when you see it.
Go ahead and remove the board from the unit VERY CAREFULLY (the female pin sockets break VERY VERY EASILY from what I've heard, so be very careful).
Next, we will need to connect the PX6/5/3 to the computer through USB. For that, we will have to make a custom cable. Here's the link to the forum where they explain how to make that cable in detail: https://forum.xda-developers.com/an...px3-5-headunit-mod-recover-flash-som-t3766892
Shoutout to @marchnz , he's a genius and without his help I certainly would have wasted my $400 I spent on the headunit.
So long story short, take a USB to something cable (the ones for your phone, for instance), strip it, and solder some resistances to it in the EXACT SAME WAY as in the pictures in the first post of the forum.
Now, connect the cable in the same way as the pictures if you have a PX5 or PX3.
IF YOU HAVE A PX6 find out which pins to connect in PAGE 2 of https://forum.xda-developers.com/an...s-development/px6-maskrom-mode-t3989407/page2 , in the pictures of a post by @oton .
Now download Androidtool here: https://github.com/rockchip-linux/tools/blob/rk3399/windows/AndroidTool_Release_v2.52.zip . This is the software that is going to let us access the mode I was talking about earlier.
Once you have it install, restart and plug in your USB end of the cable. Open the device manager on windows. If you see an Unrecognized device pop up, or a malfunctioning USB, you will need to install the drivers. Here's the link to where you can find an autoinstaller: https://github.com/rockchip-linux/tools .
If, after all, you still are having issues with the drivers, you'll need to install them manually. So right-click on the unrecognized device, update driver, browse my computer, let me pick, Have Disk, and then you find the drivers that we just downloaded (unzip them, of course). Choose the driver, and close and re-open Androidtool.
If you see Maskrom device detected on the bottom, you're all set! If you see recovery device detected, you'll have to put it on Maskrom, for good measure. It might work on recovery, but I'd put it in maskrom mode anyway. To do that, you'll have to disconnect the usb from the computer (while the other end with the cables is still hooked to the board), short two pins on the other side of the board (where the heatsink was) (for a PX6, you can find out which ones here https://forum.xda-developers.com/showpost.php?p=80641439&postcount=435) (for a PX5, I belive it will be on the thumbnails of the first post here: https://forum.xda-developers.com/an...px3-5-headunit-mod-recover-flash-som-t3766892) (if you can't figure out which ones, google search for pins to put your unit in maskrom). While you are shorting those pins (maybe with some metallic tweezers), plug in the usb, stop shorting the pins, and the unit should show up in maskrom.
Now dowload an update.img from the following repository: https://yadi.sk/d/umCvHqCDzHccr/RockChip PX5 Android 9/YB . If it tells you to download something, just click on the file until you get to the .rar screen and click on the download arrow on the top right of the screen.
Important: FOR MY UNIT, I HAD TO DOWNLOAD MANY UPDATE.IMG BEFORE 1 WORKED. ONLY ANDROID 8.1 WORKED FOR ME, SO KEEP TRYING! YOU'RE ALMOST THERE!
ALSO, DO NOT DOWNLOAD ANY OTGs (update.zip), ONLY DOWNLOAD IMAGES (update.img).
Now go to upgrade firmware on Androidtool, click on firmware, choose the update.img you downloaded, and start flashing it!
You'll get a progress readout on the right side, and you'll know when its done. Now it's time to put everything back together and hook up the unit and see if it worked. If it didn't or if it's in bootlooop, download another image from the repository and try again. The only one that worked for me was android 8.1.
Okay, so now everything worked and you got your Head Unit back! But what if you had to downgrade android for it?
Here's how to bring it back to its former glory:
From where I stood (android 8.1), the android 8.1 recovery wouldn't allow for android 9 or android 10 flashing. And I found some info on how to flash PX5s recoveries, but nothing on PX6, so I went to Hal9k's website and purchased his modinstaller 2 and followed instructions. Through there, you'll have the chance to update to android 9 or 10 (up to you), by running his apk that will install a new recovery on your machine, and then flashing any update.zip you want. In my case, I decided to also go for his ROM, because of the features it offered. The whole process was 10 bucks but I think it was completely worth it (honest opinion, not sponsored). You can also opt for installing and Android 10 ROM, as I had at the beginning, but I've heard they're pretty unstable.
So that's all! Not an easy project, but at the end you'll have your unit back and running!

I'm guessing you've seen this rom thread? There's a link to the stock stm firmware in the thread, if that's what you have.
https://forum.xda-developers.com/an...rom-malaysk-rom-px6-mcu-stm32-rk3399-t4111653
When mine was stuck on the black screen, I had to short 2 pins out on the board which entered recovery mode. I then managed to get it working from there. I can post a photo of which pins if it's any use to you?

Hi! I saw that ROM, but when I went to download it it still gives me an update.zip file with all the recovery.img, boot.img bootloader.img but no system.img. I guess I could boot it to recovery and apply the update there, but I think my recovery is also gone :/
Regarding what you said though, are you talking about the maskrom mode? or something like that? Or do those pins just take you into recovery? I could try it but I don't know if Recovery will even work :/
And if they put the radio in maskrom, where do you go from there?? And sure! A picture would be more than greatly appreciated!!
Thank you so much for all your help!!!

To be honest with I'm not sure if it is the maskrom mode, I'm no expert with these things.
All I was getting out of mine was a black screen, but shorting these pins out and powering it up entered a recovery mode each time. Might be worth a try.

My board looks different from that one and I can't seem to find any pins that look like could be shorted :/
I'm at the point where I can flash update.img into the board with my computer (through connecting pins to some USB cable), but I cannot find any full OTG flash for my PX6!
Any ideas? This might be too much to ask but is there any chance you could provide me with a full otg backup of yours to flash on mine maybe?

Hi,
I have no idea how to do that, and the unit is back in the car now. I ended up keeping the stock rom to be on the safe side! Sorry.

I'm stuck in bootloop on Android 10 PX6 MTCE, headset has no HW buttons only a reset button, can't seem to access recovery.
What step should I try first? I am a total noob and don't own a soldering iron.
Paperclip and recovery?
Update.zip won't flash before rom boot will it.
If all else fails can someone post me a USB OTG?
I only started messing as Malaysk rom had no software volume change for me. Xposed install then reboot looks like a bootloop. Was my Christmas present as well

Hi,
I have same board like skipraider, when I short these two pins there is no results. Should I connect board to PC by USB cable. My radio is freezing on black screen after car logo. It happend after updating software and it was take very long time on erasing part so then I restarted radio and it never woke up If I should connect to PC by USB using 4 pin connector has someone pinout description of this connector. Where is Ground, 5V+ , DP+ and DP-?

welcome
Sorry, I don't know English, but I translate from Google. I have a problem. I updated the screen and an error occurred. And because a black screen appears after the logo appears. I can not enter the recovery recovery. The computer refuses to recognize the screen. There is someone who said it must be a 6pin. How do I get the cable that holds the 6 pin. Or is there a way to revive?
