Hello to all who read this.
My phone only shows this two modes but does not get into recovery mode at all, it only shows the first step and then it reboots form the start:

I can't get into TWRP, even if I flash a new recovery with fastboot and run the boot command.
That said I can open fastboot mode and qfil mode.
The problem occurred last night I was watching youtube and in the morning the battery on the phone was fully drained and I couldn't boot into the lineageOS 16 that I'm using (had for 1 month).
The LED light in the top right corner is never lightning up, only when is fully drained then it shows the battery is empty and some blinking red light on the LED.
Well I tried :
- to install/run TWRP it couldn't let me run it
- to qfil the stock ROM and it did let me flash it but it was the same when I pressed the power button after the flashing process
- to use the "update" command in fastboot mode to update the stock ROM on to the phone and it said:
error: update package 'update.zip' has no android-info.txt
Does anyone know how to solve this?
Please help me!
All best,
Jasmin

I had the same issue with X727. Your battery is faulty and needs to be replaced. I got mine from this guy and received an original LeEco battery albeit with 2016 manufacturing date but it works well and phone does not reboot anymore.

Okey, thanks for the replay.

Hi, Jasmin slayer!
Did that Work for you to replace the battery? If not, try to flash some bootloader and verify , If twrp Boots again after flashing. Remember you need twrp 3.3.1 for Andro Pie!

Eunavi PX6 MCU STM32 RK3399 + DSP Android 9 - Stuck at boot logo :crying:

Hello everyone,
I did something stupid I think .
To begin with:
A few days ago I installed the Lite firmware from Malaysk for the PX6 STM32: Link . Everything went fine until...
Today I installed my reverse camera, and I noticed that there where some issues, so I tought to restore the firmware back to the stock firmware with the one I found here: Link .
Name of the firmware:KC1E0110-P01-1.1.4.3.1_20200323_160300.
I've downloaded the firmware and put it on a USB stick (formatted to FAT32), the unit recognized the update and I clicked on the arrow to update the device..... After that the Unit rebooted and the startup (Opel) logo appeared. After that it goes to a black screen. I've waited and waited, but nothing happend. :crying:
I't goes to the Boot screen (Opel Logo) and continue's to a black screen. I also tried to enter recovery mode, but without any chance. There is also not so much information available for the PX6 Eunavi/Bosion radio's.
I've uploaded a video to Youtube, concerning this problem: https://www.youtube.com/watch?v=GQav_5BJWxI
What I tried so far:
Press the reset button
Update the original firmware by using the SDDiskTool and the firmware file found here: https://yadi.sk/d/IcibzBqDuAEh5Q but no result. It seems that it reacts on the GPS SD card slot by giving a distorted image.
Before I try to put the radio in Maskrom mode, this is my last hope.
Please can someone help me further, I also contacted Eunavi for support.
Thanks in advance!

Update 03-07-2020:
- Tried it again by disconnecting the battery from the car, but with no result.
- Flashed the recovery file through the rockhip Rockchip Create Upgrade Disk Tool v1.53 on a normal FAT32 USB. Nothing happends.
- It seems that only the GPS SD CARD slot is responding with booting up from SD. When i put the micro SD card in the GPS Slot and boot up the device, it gives a distorted screen.
- I also contacted Bosion and Eunavi, Bosion is responding but doesn't want to help me with how to enter the recovery mode.
Bosion confirms that Eunavi is just a reseller of these units. I advice people the next time to buy directly from Bosion. They are responding fast.

just connect a keyboard on BACK SIDE USB it is important front side doesnt work connect via backside usb press ctrl+alt+del device will restart than rapidly pres i key while holding alt + printscreen pray god for me

or just reflash the firmware

Stuck on Boot

A few years ago, I installed a custom rom (Havoc OS) on my N910C, I didn't have any problems with it til 5 months later, it started freezing randomly, so I decided to go back to my stock firmware. I installed it using odin as usual, but for some reason, after flashing, it was stuck on this boot text

I know I had installed the right variants because I remembered my CSC code was Vietnam. I also tried other rom regions but nothing seems to work
(I tried UK, Australia, Philippines, Arab Erimates, Canada, New Zealand)
I even tried to flash the full firmware (AP BL CSC CP AND PIT) but I don't seem to make progress. I don't know what I did wrong? Did I hard brick my device? I can still access Download Mode but that's all it can do, Please I need it to fix it asap, any help is greatly appreciated.
I also noticed that you can fix a hard brick device through an SD CARD and I don't have the debrick file and I am confused with the procedure.
Phone Details:
SM-N910C
Vietnamesse
Treltexx
(You can ask for more details)

Update: I downloaded a debrick bin file from a website so I decided to flash it using win32diskimager with my FAT32 sdcard, I inserted that card from my bricked phone and I powered it on but nothing seems to be happening? It's just on the Boot screen, any help please

Mostly, after reinstalling a stock rom you have to make a factory reset to boot it normally.
Go into stock recovery and delete cache and perform factory reset.
Hope it works.

Head Unit wont boot please help

Sorry for creating another new post but having a nightmare, I have had an android unit installed for less than a week and tonight it has got stuck on the logo and won't boot
its this model https://www.ebay.co.uk/itm/384770479698 brogotek android 11 it was working perfectly well (apart from not remembering position of music tracks) I had been out and about driving most of the day (around 15 stop/starts if that makes any difference) up until around 6.30pm GMT and booted up fine everytime until then. I understand the unit is rooted as I guess most chinese type units are, then around 8pm I got in and it would not boot
It powers on to the logo screen but will not go any further and the lights on the buttons do not illuminate when i put the headlights on the journey was around 15 mins and it did not move beyond this screen, tried reset button, and press and hold reset button for over a minute

After a bit of trial and error I managed to get into the recovery mode or at least I think it was, Power on and repeatedly tap on power button, I got the word "detected" in green and then I got this "
So it seems there are no recovery files, it did come with a usb drive in the box but nothing on it, I checked on a partition manager and this was the result
I have no idea what the unallocated space is but tried it in both usb ports on the unit and still getting the no update udisk or files message so can only conclude there is just nothing on it.
I have messaged the seller as it has 12 months warranty but can anyone help, could I get a rom even if its just a bog standard android rom to get it running??
Please help

Well kudos to brosmartek customer support, they have sent me some recovery files and I am now back up and running, took less than 10 mins

Brosmartek have sent me their official files, just needed to unzip onto root of a USB drive, plug it in and reset into recovery mode, it worked a charm, reset to factory settings and working great

Hello,
I have exactly the same problem. The screen is stuck, I cannot enter any recovery mode and if I tap on the screen there appears the same message: "no find update udisk or files. please check"
How did you enter the recovery mode?

Hi
Looks like exactly the same issue I had
I contacted the manufacturers(brogotek) on the ebay sales page and they sent me a link to download recovery files.
I downloaded and extracted them to the root of a usb drive, plugged in and reset the unit and it recovered

Please be aware this was sent for a brosmartek android 11 MTK8667 unit, I have no idea if it will work for other units but I hope it does work for you
file must be extracted to root of usb drive, and all files and setting that were on your unit will be lost
Power on unit, press reset button during power up and it might recognise the files and update, if it doesn't find the files automatically, then rest again and do whatever you did to get the screen you posted above
Good luck

[HELP] Bricked PX5 HZC, can't open recovery.

Hey y'all. I tried updating my PX5 (I had the latest HZC mcu installed) 6.0.1 to android 8.0 using this guide
After booting into recovery, I tried to select the update.img file through the SD card but nothing happened.
After nearly giving up, I decided to try the same thing using USB drive. I was able to select the img file, they screen showed a few lines of text and just instantly turned off.
I tried to boot it, enter recovery mode or what not but nothing happened.
If I hold the RST button for 10s~ the non-phsyical side buttons blink for 5s, but nothing happens. I was not able to return back to the recovery mode.
Is there anything to do to solve this? My PX5 has 1 USB slot and 1 TF slot. I assume it does not have GPS sd slot so that's why the file could not be read, and either I had a corrupted file on my USB drive or it's just impossible to do through USB and it bricked my device.
I would appreciate any help with solving this brick, It was a mistake trying to upgrade from the first place..
If there is nothing to do, i'll just go and buy a new head unit, I wanted to upgrade because it lacked some features and the UI was very simple and outdated.
I don't have a photo of the MCU, but i had the MTCE_HZC_2.94b installed from here: https://disk.yandex.ru/d/umCvHqCDzHccr
I also downloaded the update files from here, following the guide above.
Before updating the MCU, I had the MTCE_HZC_2.74 installed by stock. The MCU update worked well, the android upgrade failed utterly.
Now the unit won't turn on at all and there is a black screen. long pressing the RST button until the side buttons blink does not boot the device into recovery. seems like even recovery got corrupted somehow.
After some research, I found out that I can use OTG cable to flash the firmware and recovery using a PC.
Will I be able to flash android 8-10 directly instead of flashing the android 6? or I'd have to flash directly android 6?
If so, where can I get the frimware/img file i'll need to flash?
EDIT:
I tried to connect the system to a laptop using USB A to A cable but the rockchip tool did not recognize it..
any other ways or the unit is lost?
