[Q] Desperate for help with booting

Hi - I'd really appreciate some help with trying to boot my A500.
I have spent hours over the last week trying to boot my A500, and am literally going mad, so thanks in advance for your time reading this - and all the incredibly useful posts that have got me this far.
About 2 weeks ago - my A500 froze on a webpage, and the screen was unresponsive.
I tried turning the unit off and back on again, and it just hung on the acer screen.
I did A LOT of reading around - and tried the following
- Paperclip in the reset hole
- trying to USB the tab to my PC. Windows doesn'tt recognize it. I have installed the Acer USB software.
- Volume up with power on and the toggle switch
- Volume down with power on
- emailing acer tech support, twice without a response other than the auto "You will receive a response within 24 hours"
When I do the volume down and power on - I get the Android icon with the exclamation mark, then the tab boots and I get to a screen asking for a password.
I have tried my google password without success. I have never set up a password to lock the tablet.
I have then downloaded what seems like a hundred ROM's copied to 3 different micro SD's with a variety of different formatting. Saving the files as update, update.zip, and their original file name, and unzipping them on the root of the micro sd card.
When I try the volume down and power - I still get the exclamation mark - and eventually directed to the password page again. I see the icon to show there is an SD card in the device at the bottom right of the screen.
I have also tried plugging in my wireless USB keyboard - doing the volume down power thing while pressing home on the keyboard.
I get the following options:
reboot system now
apply update from external storage
wipe data/ factory reset
wipe cache partition
I have tried them all. Reboot system takes me back the password prompt.
When I apply update from external storage - I get the following message:
E:unknown volume from path [/sdcard]
E:error opening /sdcard: No such file or directory
E: unknown volume for path [/sdcard]
It seems to me that the a500 isn't picking up the update.zip or recognizing the micro SD card.
Does anyone have a link to a stock ROM that they know to work (I have downloaded many - but get the above scenario every time)
Any advice on the password?
Any advice on flashing the ROM - why isn't the A500 picking up the micro SD card - when I know it has read these cards in the past?
I bought the device from a company called valuetech ltd through Amazon UK, who gave me a 3 month guarantee, which has recently expired. I have the box etc.
I haven't rooted the A500 at any point, and haven't installed anything other than the stock updates.
This is driving me demented, and I would genuinely appreciate any help. Thanks for your time reading this.

Well, seems a pickle you have yourself in.
Have you tried this?

You may have to download the Android SDK first, and then the google driver pack to get ADB working.
You might be able to get an ADB connection working. Maybe not. When your pc asks for drivers, let it search your system. It should tag the Android Debug Interface. You may have to manually select the driver, and ignore the warning.
Or it may not. But it's a good place to start.
It's extremely difficult to "hard brick" an Iconia tablet. Honestly, I have never seen it happen as long as there is life to it. It's just a matter of finding the correct method.

purrty much

He's definitely right... moscow is always right the acer basically cannot be bricked, unless you smash the thing or something. Look over my posts as well as the one moscow posted, I had a "brick" scare not too long ago and I had to figure that out. Should be able to guide you in the right direction.

[Q] 2DIN 'S07' Android 4.4 Using RK3066 - Root?

I recently bought a generic android head unit from Ali Express. It actually works well but I really need to connect it to a CAN bus and write some additional software (background: I want to replace the factory unit in a Nissan Leaf, so it needs to display some vehicle info, show the heater settings and set up the charge timer). I have experience in Android app development and embedded Linux, but I'm still a 'noob' when it comes to Android hacking (root access etc).
I'm pretty sure I will need root access to do what I want. It has 'CAN tx / rx' pins on the back, and I am pretty sure they are wired to one of the serial interfaces internally (I will need an adapter to convert UART to CAN as well). I played around with an app to access the serial ports (i.e. ttyxxx) but I didn't have permission to use many of them - probably the ones I wanted!
I don't want to re-write the existing music player, amp control and radio; I just want to add a new app to carry out my vehicle-specific functions.
I tried the root process given here but it didn't work.
Here are the device details:
Model: S07
MCU Version: MTCB-HA-V2.60
Android Version: 4.4.4_01062015
Kernel Version: 3.0.36+ [email protected] #278
CPU: ARM7 1.6G x 2
CPU/SOC is an RK3066 on a modular board. Pictures attached.
It doesn't have any physical buttons except reset - there are touch sensitive buttons for power, back and volume. It has one SD card slot for map data and no USB on the front (several on the back).
I haven't figured out how to get to the recovery console, or connect it to a PC via USB.
Any suggestions for how to root? Or get to recovery console?
Anyone else with a similar device?

Check out the Huefi thread above. It has everything you need. first page covers root. basically, download the rom you want, put it on the GPS SD card, insert it, and wait for it to ask you to update. Once you do that, it will be rooted. there is no other way to root it if it has 4.4.4. DO NOT INSTALL A MCU file for it unless it is for HA devices. HA is the manufacture of the unit, and if you use an MCU file for a different device, you run the risk of loosing the physical buttons on the unit. This can be repaired by going into recovery and flashing the HA MCU, but that is a lot of extra work

Hi! Thanks for your reply.
I was wary about installing a new image because I don't want to lose the existing radio app and amplifier controls (which are specific to the device rather than the RK3066 SOC module, if I have understood the structure correctly).
* Would a new image replace these apps, or are they actually in the MCU firmware anyway?
* Can I back up my current image first? I looked at some backup tools, but they all needed root access... =Catch 22.
Sorry for noob questions... I'm getting the hang of Linux but still new to messing with Android at a low level. I'd love to play around with a stripped Ubuntu or similar on the device, but I don't want to have to write my own software for the radio parts - at least not yet.
BTW do you know how the bootloader system works? Is it possible to boot from SD card or USB (therefore allowing some other OS to be booted without replacing the onboard image)?

I cant help with the bootloader issues, but I can with some of the others:
-Radio and Amplifier apps are the same on all units, or should I say is compatible across all units. If you were to go into the settings, then factory settings and enter 126 as the password, you can see all the settings you need to make sure your unit functions after upgrading your rom image.
-You can not back up your factory image. its not possible. You can always reach out to your seller and ask them if they will send you a copy of the factory firmware.

SUCCESS! I just downloaded and installed the latest image from Malaysk (I think?) and it looks like it is working well! Radio, music player and amplifier work, and I have root access. Woo! So far so good... Thanks!

Hi, I also didn't know the screen resolution, and it is not mentioned on the "About" screen.
In the settings menus, I found some options for recording a video of the display (I don't know why!) and the maximum resolution there was 1024 x 600. I figured that you wouldn't bother to record at higher res than the screen had, so the resolution must be 1024x600. This seemed to work!
My stereo has absolutely NO branding on it anywhere so I don't know whether it's a clone of Huifei or something else, but it worked with the "Malaysk" firmware, which I downloaded from the Huifie file repository (linked from here), under firmware->Malaysk ROM->Malaysk DualCore RK3066).
I picked the bottom one (12th Jun 15, 1024x600 with different launcher).

I just installed the same unit. Only complaints are streaming music via Bluetooth only works if you open up the Bluetooth app (probably because android doesn't act as a Bluetooth sink). The other issue is, I cannot seem to change the brightness of the screen...its a touch too dim for daylight (I have a convertible) and a bit too bright for nighttime.
Glad to see you got a custom rom working.

Hey jcolebaker, do you think you could post what the LCD model number is? Is it a Hannstar HSD070IFW1-A?

Sorry not sure what the LCD is - I don't want to pull it apart. It has a board on the back which has the following on it:

That's soldered to another board that says:

Update question
Do I burn the update.img file to the sd card or do I simply copy it? And does it have to be my gps sd card or can it be a spare blank one?
Thanks

Doesn't appear to be an img file in the context of "burn it" so I think that answers that question (just copy it) The head unit doesn't seem to do anything when I drop it in though (either with it on when I insert it or with it already inserted during a reset). Any thoughts?

The file should be "update.zip". I used a new SD card - try formatting one with FAT32.
You just copy it to the card and insert it - I think the stock Android image automatically checks for update files that look like this, and loads them. This process worked OK for me - if not then hopefully someone here knows more about the update process than me.

HI !
I also try to root my 2din android without success... I have the same as your and I fail to get recovery and the android can't detect the update.img (or update.zip)
I have tried many tips, my sd card is in fat32, well detected by android ...
Do you have the tip to access to the recovery ?
Thanks

I think the file is "update.img" not "update.zip". Anyway I have not figured out how to get to the boot loader on mine, and I never got any recovery console. Sorry I am too much of a beginner myself to suggest anything.

Instead of flashing a new image, go to the factory settings and type in *#hct#root#
This should give you root, no need to flash a new image

Bonjour.
If you would like more than root and you're still having trouble getting into recovery with your Hot Audio RK3066 1024x600 2 DIN Head Unit, the steps below have worked for me when the system does not automatically detect the mcu or update.img.
*** Prior to flashing any OEM or Custom ROM firmware, I recommend using a backup app like Titanium to save all your existing apps and data to your external micro sd card or usb memory stick.
1) Install Quick Boot or a similar apk from the play store.
2) Attach a wireless usb or usb keyboard and confirm it is working as intended. I use a Lenovo N5902 but most usb or wireless usb keyboards should work for this task.
3) Make sure you have the update and or mcu image file on your gps micro sd card or an attached usb memory stick (not the zip file).
4) Open Quick Boot, select recovery, and the system will shut down and boot into recovery.
5) Use your usb keyboard to scroll or arrow down to the update option with correct img file location, then press enter to execute the mcu or android firmware update or both.
6) After you update the android firmware, it is highly recommended that you go into the Settings > Backup & Reset, and select reset to factory and check the box to delete all data from the internal sd card. This reset to factory and internal sd card wipe should give your updated android system a clean start and help avoid system issues due to left over data from the previous firmware.
7) Delete the mcu and or update image from your external micro sd card. Done.
Hope this helps...
Best to all,
R

Why don't you just flash Malaysk's ROM? It's easier and the ROM is much smoother than stock.

By your username I assume you're brazilian, right?
Where did you buy your unit?
This night I've managed to talk to a Caska sales director for LATAM and he said that they cannot give the stock ROM for security reasons. I still have problems with the clock and the startup also (blank screen). They say their engineering team is working on fixing that issue, but China has a holiday that starts today (Oct 1st.) and only ends Oct 7th. So I'll only have an answer after that day.
Maybe you can talk to your seller and see if he gives any support (I bought mine at www.rcmultimidias.com.br).

Sure I am, you are right.
I bought mine from aliexpress. I found a update.img file in some folder, but I'm not sure if it is the full image. I opened that image in a linux box and looks like we have everything, there some ext4 images, boot image and a lot of other files, but I'm not 100% sure about it. May be somebody with experience could verify that.
Another annoying thing is the music and video apps not reading files from sdcard, they only read USB and inand. I've modified the Music app to point it to the correct path, but I couldn't install it back to the unit (It fails to install without any error). At least if I could reassign music and video buttons to another app, that would be ok (VLC is working fine, just need to adjust volume).

Normally you have to boot in recovery mode, something that I still don't know how to do for this unit, and then use that update.img to restore. See this thread http://forum.xda-developers.com/showthread.php?t=2660662, there some possible procedures there and may be one of them work for the caska.
How big is the update.img file they sent to you?

Here you go with the update.img.
https://www.sendspace.com/file/mjkgfj

Here I posted a video with all the problems I'm experiencing with this unit. The main problem is that I cannot setup the right time, so all Android apps are useless (they require a secure connection to their servers and this is only allowed with a valid certificate [that needs the correct date]).
I was trying to root my unit so that I could use ClockSync to fix the time every 30 seconds (it resets after 1 minute), but had no success on that.

Hi!
So, where did you managed to talk to Caska? I've tried contact with Caska Brasil with no success (they say they do not offer support for Android units), and Caska Global didn't give any answer ([email protected]).
I've downloaded your update.img, but it's for CA712 and my unit is a CA380-XLA, I'm afraid to brick it. Have you tried entering recovery mode pressing reset and power buttons the same time?

I can reassign the screen buttons in my unit. In the settings, go to the last menu: "Shortcuts". Not sure if there's a way to reassign the physical buttons without modifying the original ROM.

I'm newbie as well, but I know that you must need possible clue, since you brick your unit. I'm afraid to point you to the wrong direction, but I believe it deserves to try. I saw some threads discussing about the bootloader and connect via USB. Looks like to have to install the usb driver for the rock chip (RK3066, since it is dual core and there is a file RK3066Loader_uboot_upgrade2_4_16gok.bin in the update.img file). I don't have more details on that, but may dig deeper.

I've tried pluggin a USB to the unit and connecting it to my PC with no success, no devices are recognized. I have developer mode active but no options to enable USB Debugging.

So, I was able to extract all APKs from the file danylam hosted, and it's quite different from my unit: I have only one "Settings" menu, and in my unit some essential apps weren't installed (like HBS_Carkit_ChangeLogoUtil.apk and HBS_Carkit_SyncGPSTime.apk). I've installed them and solved one of my problems: car starting with a GMC logo. But the SyncGPSTime.apk isn't being called by any applications, so it's not starting (and I cannot start from itself).
Then I tried installing the Settings.apk that came with the ROM and ended up with a non functional setup menu, unfortunately. Since in that version most settings are changed from the "Android Settings", and I couldn't install that apk (it shows me an unknown error), I've lost some essential menus.

So, I was able to extract all APKs from the file danylam hosted, and it's quite different from my unit: I have only one "Settings" menu, and in my unit some essential apps weren't installed (like HBS_Carkit_ChangeLogoUtil.apk and HBS_Carkit_SyncGPSTime.apk). I've installed them and solved one of my problems: car starting with a GMC logo. But the SyncGPSTime.apk isn't being called by any applications, so it's not starting (and I cannot start from itself).
Then I tried installing the Settings.apk that came with the ROM and ended up with a non functional setup menu, unfortunately. Since in that version most settings are changed from the "Android Settings", and I couldn't install that apk (it shows me an unknown error), I've lost some essential menus.

Hi,
The only way to talk to caska global is using skype (coagent,service). Normally they are online at 9pm (Sao Paulo time).

I'm newbie as well, but I know that you must need possible clue, since you brick your unit. I'm afraid to point you to the wrong direction, but I believe it deserves to try. I saw some threads discussing about the bootloader and connect via USB. Looks like to have to install the usb driver for the rock chip (RK3066, since it is dual core and there is a file RK3066Loader_uboot_upgrade2_4_16gok.bin in the update.img file). I don't have more details on that, but may dig deeper.

Can you tell me how to extract this bin file from the image?

I found the update.img in my CA712 with a simple search for update.img. I used the file browser and and did the search from / device.

This is the linux tool to open the image http://forum.xda-developers.com/showthread.php?t=2257331
command:
Code:
./imgrepackerrk update.img
It creates a update.img.dump folder and the bin file should be in the update.img.dump/Image
Boot.img is compressed and if you want to see content do this:
Code:
mkdir boot
cd boot
gzip -cd ../boot.img | cpio -i -

Tried searching mine but couldn't find any *.img files. But at least I've managed to uninstall the CA712 settings from my unit and revert to the original one.
Looks like your unit is a little bit different from mine.

Brand new UIS8762 qled 6gb 128gb 8core never started, and no support from Witson

Hi,
I've been googling and searching here and on Youtube for three weeks and I can't find any help.
My brand new head unit doesn't start, and has never started. The touch buttons don't work so after hours and days seaching the web I found out that I could at least get it to the boot logo by pushing a pin into the reset hole for 10 seconds, another short push and then a third push for 5 seconds, but that's about it.
Sometimes when I do that I get to a "no command" screen and then nothing.
When I contacted Witson who sold it to me, they sent me a file to install, but the problem is that the update stops (around 80-90%) and reboots before it's finished. After 3 restarts/reboots of the update it just goes black again. After sending several photos and videos to Witson of what's going on I asked for a refund and then they just stopped answering me. Nice, huh. (And I've followed their instructions to push the reset button when the boot logo appears - let it reboot - push the reset button when the boot logo appears - let it reboot - push the reset button when the boot logo appears.
So now I'm stuck here with a head unit that's never been used. Could there be a chance that they sent me the wrong update perhaps? I'm not used to head units but I've tried many things to solve it. I can't get into recovery mode, god knows I've tried for days with maaaany different tricks picked up on the web. I've even opened it up and tried to reset by short circuiting the special poles people say you should do. Nothing helps. I've tried to figure out what other brand sells these to find another file to install, and so far I've tried at least 10 different files, both USB contacts and three different USB FAT32 sticks, but no difference. Boot loop is the only thing this head unit is capable of.
If anyony could kindly assist me it would be extremely appreciated.
I'll try to post some pictures for you. I don't even know the proper name of this thing.
It's supposed to be a Witson DHG (W2-DHX1001) with Android 12, , but it seems to have many names. As I said, it's never started up properly and I've never played with a device like this before.
Many thanks!

This looks like a UIS 7862 FYT unit. DO the files they sent include a lsec6315update and a 6315_1.zip?
Normally, when the update fails you will get a message in red about the failure and the unit will reboot after 5 minutes or so, yours just reboots?
Anyway, if you got the unit from Aliexpress the safest thing would be to open a dispute with them.

Hi,
Thanks for your reply.
Thanks, I'm not by the computer right now but they sent me a 2,1gb zip-file with a zipped 6315 file name in it. (Does that make sense? ) Not sure if both those files was in that package, but one of them was.
I can't recall the exact name right now. But they just wrote that I should unzip the big file as is onto a USB stick and do as described earlier.
There was no red alert text when I used the file. Only reboot after reboot at around midnight 80% install. (One of the other files I downloaded later from the web showed that red failure text)
I did open a dispute and was reimbursed $160 of the $400 I spent in total. So here I am $240 down and a piece of glass.
Would be fantastic if someone has a file that fits this head unit or someone knows if there's a possibility that the main board or something else is broken.
Cheers

You definitely have a FYT unit.
There is plenty of info on this unit in this thread.

Ah, yes I recognize that thread. Been reading a lot in it but I couldn't make anything out of it in relation to my unit. I guess I have to give it another go and see if I can make anything out of it now when I know it's a FYT unit, thanks.

Short version:
Get a FAT32-formatted USB stick, good quality. Bad USBs may cause setup to abort.
Copy the firmware files (minimum: config.txt, 6315_1.zip, lsec6315update and updatecfg.txt) to the stick.
updatecfg.txt should contain
test
twipe_all
config.txt should look like
#test
#ro.fyt.launcher = com.android.launcher04
sys.fyt.bluetooth_type=1
persist.fyt.zh_frontview_enable=false
sys.fyt.ec_version=6
ro.fyt.splitscreen=0
persist.syu.camera360 = 1
# 0不带360 1带360
persist.lsec.pip_rect_clear=true
ro.sf.swrotation=90
persist.lsec.enable_a2dp=true
ro.lsec.btname=Bluetooth 2
persist.lsec.iphone_usb=true
carmark#0
persist.sys.navi.carmarkset=0
launcher name may be different, depends on firmware version.
Make sure 6315_1.zip and lsec6315 update are both dated either before or after July 2, 2022. You cannot mix on from before with another one from after.
You can get a suitable firmware from here. Look for the 7862/9" 10" line ( or 7862-9"-10"-360: if you have 360 view)
Insert the USB and start the unit. You may have to reset up to 5 times until it boots from the USB stick.
If you get an error message, post it here.
If you don't and it still aborts at 80% chances are you have a HW failure

Amazing, thank you for the detailed explanation. Well needed for a noob in this area.
I'll try it out when I get back on the computer later tonight. I guess the night sleep is canceled.
Thanks again, very impressive.
I'll get back to you as soon as I have any results.

I think that this file update he got is not for his device, it does not recognize hardware and stops in a middle of process of install.
Install other updates suitable for your model and year and see if error repeats again.

Hi Anton,
Thanks. It's what I suspected too. But it seems all the different files I've tried has behaved the same way so far. I'm trying this file that was recommended by @m00n61 here above. So far to reboots and same thing. Stops and reboots at the exact same spot. Switching USB and USB stick in a few minutes for continued trying.

Yes, unfortunately it looks like it's the same thing with the recommended files (7862/9). It reboots at the same point at the install and no error messages. I'm trying out the other USB input now and will then try yet another USB stick.
Thanks again.

So I tried to install both the whole file and only the necessary files @m00n61 mentioned earlier. And I tried this on both of the USB inputs and with three different USB sticks. All with the same outcome. the install stops exactly where I showed in the picture in the first post, and then reboots, restarts the install and it goes on like this three times until it just goes black.
Is there any other way that may help? I've read about connecting the head unit to a computer with a USBa-USBa cable and some sort of sofware.
Thanks for your input!

Yes, including flashing of ROM but it must be done with guidance and by a pro...
But it is last resort, let's try something else first.
Format SD card (if device has slot for it) in FAT 32 not exFAT with default allocation settings - not USB drive but SD card !
- if device has no SD card slot use any SD card reader if you have any and insert it then into USB slot with update files on it
- before unit boot try tapping with one finger on the middle of screen till see message DETECTED
- let the update begin
- if same error appears - press RESET button rapidly each time units starts for 5 times
- as soon as unit starts again tap the screen with all five fingers till recovery mode begins (message erasing will apear and begin to erase system files)
- when boots again into Android download a application named FILE MANAGER from Google Playstore
- go to app
- on the left side of app there is a menu - choose ROOT folder it looks like this "/.."
- there are system files that are hidden from users
- if unit is rooted you can go inside each of this folder
- if not rooted, delete the CACHE folder
- restart unit and try update again with SD card or USB drive
Fingers crossed !

Thank you so much! I'll try it out tonight! (it's morning here)
The unit has no card slot so I'll give it a go with a card reader.
I've read about the five finger tap (which didn't work on this one) but never the one finger tap. Looking forward to try out your suggestions!
Thanks!

Five tap is not working on every device, every device has different way.
You must find your way to get into recovery mode and get system to clear cache and junk files
Also, maybe you have residual update files left on main folders like factorysettings.bin log files mem.ini etc. delete those too !
BTW you can go into recovery mode if you can access Android and go from infotainment menu or from factory settings (accessed with PIN code)

Yes thank you, I've yet to figure out how to get into recovery mode. And I've never been able to start the device, so recovery mode seems like prio one so far, if I can't get any of the files to work via SD card etc.
Thanks!

Help Requested: Bought a TS10. Sub Pre-out stopped working after S/W Update to TS10.2.2_20230311.103922

Greetings!
I bought a radio for my car. Everything was working out of the box yesterday. I did a S/W update this morning and updated to TS10.2.2_20230311.103922 this morning. As soon as I did that, the sub pre-outs went completely dead. I did test my amp and everything downstream is getting power. I don't know what happened. The update was successful. I don't know what the previous software version was before updating.
I have no idea how to fix this. What should I do?

Hi, request an update offline from your seller (install thru USB stick) or go to factory settings menu and restore original software - downgrade (this will delete all files and folders created after first use and put clean install)

Duplicate post.

The seller told me not to perform a factory reset because it'll delete the APK and map files. How would I get those back?
Update: I performed the factory update. I found the "APK Installer" on the radio. I was able to install TLlink, and a few other ones.
Thank you!

Actually no. It's so much much worse. The headlight illumination wire never worked (before or after update). And now the sub pre-outs do not work in TLink. They do work in Bluetooth or the Radio. That's it. I worked on the car for 3 hours last night. I did numerous factory resets. I can't get it to work right.

Thank you! I can let you know this information tomorrow! I don't have access to the car right now. The radio was from AliExpress. I'm on Android 10. The radio is called the T9 version. I did post on that Q&A post too.
I had issues where the amp remote wire was not being turned on by the radio (power cycle with a paperclip fixed that).
Now I'm having issues with the sub not providing any audio while using TLlink. The speakers even sound really awful when using TLlink.
I also accidentally flipped the boot logo screen for the Android logo. Not sure how to put it back the way it was...
The seller did give me this file: "TS10.2.2_20230311.103922_THEME1-11.rar" I'm not exactly confident this will do anything when the Factory Reset didn't.

It has obviously theme pack for changing theme or UI of device.
Boot logo is minimal concern. Boot logo can be changed in factory settings mode (access with pin code ussualy 8888 or 126 or 123456).
Please do also :

I sent you an email with a link containing the .rar file the seller gave me. It is the current software version for the radio. I asked them to provide me with the original firmware file they send with the radio as well. I'll get that tomorrow.
Here is the photo you requested.
It is running Android 10. Although, it's supposed to be Android 11. I don't have canbus on my vehicle or a factory digital amp.
I tried plugging my phone into the USB plug in the back of the radio. It didn't connect to the radio. It briefly was charging, but I was unable to use Android Auto using the wired method. I don't have the car's factory USB plug hooked up right now. I'll be doing that on Saturday. Is it possible the rear USB plugs don't provide data to the radio? The rear USB plug is 6-pin. The car's factory front plug is 4-pin.

No I did not. Since my car does not have the upgraded audio system, no canbus was needed. I was not given one.

Your file that you have sent me... It is update for unit , go to in system update where you updated software and choose not online but "local" update and then choose USB (ZIP file - files must be unzipped on formatted USB drive and attched to port prior to hit update). Let it finish and then see if helped. If not I'm looking for same update on net, we have similar device I have TS18 yours is TS10.

Send file to USB drive on a cmputer rather than from phone. Send this zip file to a computer via mobile phone bluetooth or cable connection unzipp the files, then transfer files to formatted USB drive, attach it to USB port on head unit, go to system settings and choose local update / USB and it should start the update. It is best method.

Performing the update now. Am I supposed to check the "Wipe data and format flash button?" I didn't check it.
I finished the update. It didn't do anything. My subwoofer is still broken and none of my settings were wiped.
I tried the update again and I clicked the "Wipe Data" button. Same result.
I do have the original file the seller gave me. It's the older firmware version. I haven't tried that, but I'm getting annoyed at this point. I thought a flash was going to completely wipe the radio, including the crooked boot logo I accidentally flipped.
This is the oldest file the seller gave me. I haven't tried it yet.
