Dear friends,
I'm having and issue with my Bosion HU. I can't tell what model/type it is exactly. Please take a look on the photos.
From some time I was struggling with not working left knob (potentiometer only - pressing the button was working fine).
After much effort - replacing whole PCB board with that knob, through installing updates - nothing worked.
Today I wanted to do hard reset from recovery mode, but surprise was waiting for me... I was trying some combinations of power button and RST button to enter recovery mode and it came into bootloop...
Can you help find a way to manually enter recovery mode with this unit ?

BUMP, please
I managed to get into recovery mode through Terminal Emulator by typing: reboot recovery.
But i have another problem - i cannot navigate in recovery mode at all. I have tried all buttons, all screen places and plugged USB keyboards but none of them was working.
BUMP, Still needs help! :C

Hi guys, as i said, my girlfriend's galaxy s4 is stucked in a bootloop when she was playing farmville.
The phone is completely stock and with the last firmware.
I cannot enter into recovery, just can go to download mode, in which the phone is perfectly stable (is stable also when is charging on the pc).
I've tried almost everything and one time i was able to boot the device and enter to the home launcher, turn two pages and then bootloop.
Sometimes (two or three) the device stuck on a green screen like this:
{
"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've tried to:
- reflash the stock firmware with odin, i get no problems and the device PASS the installation but the problem isn't resolved.
- remove sd card
- change battery
- play with the power button
I've no idea on how to fix this, why i can enter into download mode and bootloops finish?
A big thanks to everyone.
Probably hardware failure. You can try to flash the rom with .pit file and re-partition as a last resort. If it still wont boot then, then you have hardware failure.
Thanks Lenny, but how is it possible that in download mode the phone is perfectly stable?
Dear all,
I have an "Unbranded 6.2" 2 DIN Pure Android 4.1 Car Stereo Radio Head Unit" which has the same specification as "AN-21 U".
For some reason, I reflash it with the firmware which is download from the Russian website-- "4DA".
The firmware works, but not all of the settings are reset even after I make a factory reset.
Therefore, I try to use the "Fullformat" firmware to clean the settings.
There are three different Fullformat versions on the website (4DA).
After I use one of these versions, it only shows an Android logo after reboot and nothing happens at all.
However, it would read the firmware (or MCU) files if I push the hardware reflash buttons (power + reset for 5 sec, then release reset button, then power button) and there would be messages shown on the screen as "UPDATE START" (and "UPDATE END" after few minutes.).
But nothing happens after that.
It always shows the Android logo and that's all. (still can perform hardware reflash.)
Has it become a brick?
How can I make it work again?

I have fixed it by myself.
Using Fastboot mode and typed by "fastboot continue". Luckily I could get in the recovery mode so it could be wiped out and rebooted as factory reset. Now I am using it without a problem.

Hi to everyone. I am new to XDA. I have a problem with Tab 4. My friend wanted to flash custom rom but he is noob about this. So I took the tablet and flashed the custom rom with TWRP. Everything went smoothly until it is stuck at Samsung Galaxy Tab4 screen. I attached the photo where it was stuck. I want to boot into recovery but sadly, home button isn’t working at all. How can I boot into recovery? Please help me ASAP. I can’t do anything to it now. Sorry for bad English.

The tablet is bricked. After flashing twrp, there should be a message in the top left of the screen about set warranty bit. The picture you posted is missing the yellow text. That's bad. Try putting the tablet in odin download mode by holding the home and volume down button plus power. Then press volume up when prompted. If you can get into odin download mode, reflash the proper twrp and try again.
If you can't get the tablet into odin mode, jtag recovery is the only option, a very complicated procedure.
I was messaging a work colleague and the messenger got frozen on half of the screen. I thought it was a video error that would go away on reset so I tried resetting in long tablet mode (sorry I am not using the correct terms) and I couldn't hit the reset button because it appeared BEHIND my facebook messenger. I was able to access it in portrait mode though. So I reset but now my screen has junk all over where the messenger was. I tried to get into factory reset but the options are behind the junk. I tried to guess where the option was and ended up clicking the update button instead and now I'm just sat here with my screen looking like this.

So what can be done?
Boot into recovery mode. Factory reset.
If you can't either the firmware is corrupted and needs reflashed or it's a hardware failure. I'm leaning towards the latter.
Yeah i did the factory reset through guesswork and its still there. I don't even know how to begin reflashing.
I am in ecuador and have no access to reliable shops.
Did the recovery screen display normally?
Nope
