My PX3 7.1.2 unit in my VW T5 is stuck on start screen "multi media on-vehicle Navigation system" after I tried to update .img file.
It just flashes the above start screen and I've tried all methods to get into the reboot menu to reset.
Anyone help?
I guess that it is hanging in recovery. Did you try to get it to recovery mode manually via the reset button?
Did you check out the "stuck in boot loop" thread? https://forum.xda-developers.com/t/px5-stuck-in-bootloop.3635412/

Hello everyone, I am new to the forums, so apologies if this is posted in the wrong section.
I purchased an android headunit, MTCB type, but immediately after installation unit does not work.
Unit is 1024x600 with rk3188. it is one of the custom fitted units to a civic, has volume knob (power button when pushed), tuning knob (also a button when pushed), disc eject button, back button, and small recessed reset button.
I am able to boot in recovery mode, and have tried everything from that menu..
I have installed different 5.1.1 firmwares, tried different MCUs, and nothing seems to work.
I always have the same problem where it displays the Andorid Auto Lollipop 5.1.1 screen, button lights are on, then it turns off.
Only way to reboot is to hold the reset and power button and boot into recovery mode.
When I connect to my laptop, it recognizes it as a rockchip device, but I am not sure if there is any troubleshooting I can try with PC connection.
On one occasion, after installing new firmware it went passed the lollipop screen and displayed the Android boot animation but hung at that screen forever.
After reboot, same issue persisted.
I have been unable to find my factory MCU, & manufacturer is of no help. My unit is: MTCB-KLD-V2.08
Installing the original MCU for 2.08 is the only thing I havent been able to do, because I can't find a download for it, so if someone has a link, that would be appreciated.
Otherwise, is this issue a factory defect, or is there some type of sleep mode it's entering? Any help would be greatly appreciated.
try wiping the data 3x and then reflash the update.img and mcu.img
the first boot will take 20mins or so (seems like it is forever)
I enrolled in the Beta Program, and upgraded to Android O. Everything was great! Until I rebooted, things were acting funny. I have played with enough nightly builds and custom roms to realize, I need to factory Reset.
Bootloop.
I was able to get into the recovery mode: and then did another factory reset from here--
Now my recovery mode is only, "No Command" Vol up + power did not get me a list of options again
So, I followed this guide: https://forum.xda-developers.com/nexus-5x/help/guide-fix-bootloop-locked-bootloader-t3608679
I got here: "click on all buttons and flash all partition files from extracted archive - except recovery ,userdata and cache."
And still was boot looping
So, I went to this guide: https://forum.xda-developers.com/nexus-5x/help/req-help-to-unbrick-t3251740
Installing the "LGUP_8994_DLL_Ver_0_0_3_23" Looks rather uneventful.
But, I booted up with Vol UP+Power
and got to the Firmware Update screen.
It's been sitting at 0% for twenty minutes... "Do not unplug the USB connection until the process is completed"
and "LG USB driver installation is needed before starting LGUP"
and I will need to close my laptop in an hour
Im lost
Edit:
Okay, I got the LGUP to install a new TOT file--
LGH791 - resulted in freezing on "google" after reboot
LGH790 - also frozen on "google" after reboot
However, my recovery mode is no longer "No Command"
So I'm going to try to Sideload an update
I Has an operating system! I'm going to update my firmware to 791 now
hmm.. .no option for "BIN" so I'm going to leave it-- i was supposed to go an hour ago
[Follow-up] My sensors were "malfunctioning" with LGH790. Upgrading to LGH791 fixed all of my sensor issues.
On my car android head unit i changed boot animation in wrong resolution and now its stuck in there. Couldn't load the system any further. I tried to bring recovery mode. It has reset and power button only. Tried some of the key combinations but it didn't work. Pressing power + reset for 5 sec and releasing reset while still pressing power button for next 5 sec, it went into different screen for short time showing,
'Start update and End update' screen
then stuck back to same boot animation screen.
I tried adb also but usb debugging is turned off so couldn't succeed. I changed the boot animation from built in system software.
I have copied this bootanimation.zip file on internal storage, not in any folder. So if i could delete this file with factory reset or anyhow it might solve the problem.
Please any suggestions or solution will be really helpful.

Hi.
When I normally turn on the power, it takes a long time for the logo to appear, but if I turn on the TV in an attempt to enter the boot menu, the logo appears quickly. But no matter what, nothing happens.
When the logo disappears, there is a black screen until the LED flashes 2. When I tried to start up in the boot menu, it boots twice where the logo appears before the LED flashes 2.
Via service uart I notice these 4 lines.
SDIO read error
EMMC: read Android image fair
Read mkbootimg error!
recovery pattition image is not proper!!
Not looked through everything yet, but can see that it reboots 5-6 times.
Have assumed that it was the firmware that was the error, but since I can not enter the boot menu via the screen, how can I load other firmware? Can I do this via I2C or SPI? Is there anyone who can explain to me how to deal with this?
Which program is preferred? Where to load the various files in the downloaded firmware for etc.
Thanks in advance.
No idea?
Does anyone have full datasheet over 88DE3100?
Hi,
the only chance is to access the Recovery Mode menu and install the the latest firmware again.
The 2014 TVs powered by Android 4.2.2 (not Android TV) have a common problem after some years, that the flash chip is broken.

Hi.
Is it eMMC? Assuming there is no point in just changing it. Does it not require programming before soldering?
Should I not be able to start the recovery menu even if the flash is defective? Can I send a commando to start of recovery mode via I2C / SPI?
Thanks for the response
Hello,
I bought a "bricked" Galaxy Tab S4 on ebay. The only info I got was, that it is stuck in a bootloop since the last automatic update.
The bootloop is similar to this one. The tablet starts with the Samsung logo, then nothing happens and after a while I end up in recovery mode. Further, if I restart or hardreset the tablet, the screen stays black. The only way to boot it up again is to empty the battery while it is stuck in the bootloop. Afterwards I can enter download mode by holding "vol up and down" and plugin the usb cable.
In download mode this text appears at the bottom left:
#reboot recovery cause [unknown]
API: 3
manual mode 1.0.0
(Similar to this thread.)
OEM lock is on and of course I can't change this being stuck in the bootloop, or can I?
I successfully flashed the stock rom T830XXU5CUE2 with Odin3_v3.14.4 and latest samsung drivers. Unfortunately it does not help or fix anything. (I used virtualbox, but it worked and said "PASS" at the end).
After some research I would like to try my luck with a combination rom, but I can't find a U5 version which I should use because of T830XXU5CUE2, is that correct?
Any ideas how I could proceed from here? With OEM lock I guess there is no chance to flash TWRP on it?
