Hi guys , i currently have a Samsung Galaxy S4-I9505 (un-rooted) . Just a few days back , it started to shut down by itself for no reason and when i try to on it again it will get stuck in the "Samsung Galaxy S4" boot up screen and goes blank again . I have tried to restart it many times in safe mode and tried to wiping the cache but it goes blank as soon as i try to press something . Another solution i saw was to re-flash the firmware using KIES , but i can't even get it to work (no LED light when plugged in to charger or the computer ) . I did call Samsung service hotline and they think that there is a problem with the motherboard so they suggest i send it to get checked . So , any suggestion on how to fix this ? Any help would be greatly appreciated . Thanks !

Hi mate,
First thing i would do is a backup of personal data and apps
Check if any of the pushbuttons is stuck , specially the power button
Can you go to recovery , can you go to download mode?
Try first a factory reset and see if it help,if not i would reflash firmware with Odin...BUT if it is in warranty still take it to them and have it fix

Hi there , is there a way for me to do backup without turning the phone on ? since currently i can't turn my phone on .
I do not think that any buttons are stuck seems fine on the outside, but after going through some youtube videos i think there might be something stuck internally ? so maybe i will take it out and try to see if it works .
I can get to the page where it shows recovery and download mode sometimes but if i press a button to select an option it will go blank straight away .
Sadly it is not under warranty anymore , maybe i will open it up and give it a try first .
Thanks for the reply !

Hi ,
unfortunately no you need the phone to be on.
Even if the buttons look fine they may be stock , if you know how open the phone and try to wiggle them

Well, you could try and flash a custom recovery and the perform a factory reset.
Or you can reflash the rom you have.
Factory Reset and if that doesn't work try changing ROM

Whatever, I heard that on S4 you can't switch from a higher version of android to a lower one ( eg: from 5.0.1 to 4.4.2).. a link where I can find more informations please

Hi everyone,
I hope you have experience with mentioned head unit and could help me with the problem I have.
Mine head unit is running Android marshmallow 6.0
And was working without any problems until few days ago when it went into a boot loop.
I have tried many options mentioned on this and other sites but I am unable to recover Android installation. It doesn’t go into the recovery mode with any combination I have tried, reset+power button.
Only success I had to get into recovery mode is with the usb keyboard, and alt gr + pr.scr. + I combination. This way I can boot into recovery but problem still remains, when menu pops up keyboard stops working and I can’t navigate through the menu, buttons on hu are also not responding.... I have tried different USB ports, also tried to navigate with the mouse but I am still stuck here...
So what could I do? Any advice will be so appreciated!
Hey guys,
I bought a Navigation System M779 (androidautoplayer.com) for Suzuki Grand Vitara from AliExpress one month ago.
At first, everything was fine and I was very happy about it. Nothing to conplain about.
Then I went on Holidays for about 14 days, in which the car wasn't used in any way.
Yesterday I started the car for the first time after Holiday, the battery still was fine but the radio did not boot. The screen stayed black and the Buttons did not light up.
After checking the Plugs on the back, the screen showed a Bootlogo, but got stuck.
I did not modify anything and everything was fine until Holiday.
Can you please help me?
Pressing reset did not change anything. Sometimes, selecting reverse does activate the rear cam. That's it.
I don't know how to enter Recovery or how to install the Firmware.
It is an Android 9 PX5 System. This is everything I know.
Kind regards
Robin
May be able to reflash firmware using this method - https://forum.xda-developers.com/showpost.php?p=79144579&postcount=2 assuming that the manufacturer posts firmwares on their site, or can provide it to you via download, email, etc.
Thank you for your reply.
I tried some Firmware-files, just to see If the head unit enters Recovery. This failed.
The manufacturer also replied to a Mail, telling me that they will hand me out a possible solution next week.
I will wait eagerly.
Hallo again,
unfortunately the manufacturer did not provide a solution to recovery my Head Unit.
I managed to get into the Recovery Menu and tried to wipe data, but this had no effect at all. Still stucking in bootloop.
The information given in Rcovery Mode are:
rockchip/rk3368/rk3368
9/PQ2A.190305.002/hct204281503
userdebug/test-keys
Recovery V9.0.5.
Supported API: 3
Can anyone please help me restore the Head Unit?
Kind regards

Did you try to disconnect the main connector from the unit and leave it that way for a few minutes ?
And then reconnect it again.
Thanks for your reply... But I think I did very stupid today and bricked the device.
Reagrding to this topic "forum.xda-developers.com/android-auto/android-head-units/head-units-rockchip-px5-mcu-csn2-t3912413" I flashed my device with "Fake Android 10 - July 6th 202007061156".
The flash ran smooth without any errors. But the screen seems dead now.
The buttonlights still turn on and do blink if I press the powerbutton for about 10s, but there is no bootlogo or anything at all.
I cannot enter recovery anymore.
**** happens?!?
Kind regards

Hello guys. First of all, I've been searching for weeks for any similar situation with mine but couldn't find anything. I have Unbranded Chinese Android Head Unit running Android 4.2.2. with physical button and a reset pin. I tried tonnes of ways to get to the recovery with any possible method and nothing seems to be working.
can anyone show me how to get into recovery or force hard reset on the unit ?
I have attached a few pictures of the Unit info and the circuit board.
i tried to connect a USB keyboard to my Unit and pressed PrtScr + "E" but my unit did not show factory rest option. you can see what happened in the attached video
i will be thankful for you, if you tell me how to get into recovery mode of make a hard factory rest or install a new ROM.
Thanks in advance .
