How to Reset Samsung Foucs

Folks,
I got a new Samsung focus (Re 1.3) yesterday , followed a tutorial from youtube to install custom rom. Everything went good , like installing MAGLDR and later reset and installing ROM. After installing ROM, the guy told that teh SAMSUNG logo appears for a long time and we have to poweroff by removing the battery. I did the same but nothing was working on my mobile. It starts booting shows samsung screen and stucks at the following screenshot, i tried to connect it to laptop as it showed in screenshot,but even hours dint helped anything. Now i can only see the download mode , not even the format mode. I searched how to reset to factory setting, but nothing was found useful. I found two posts one with instructions and files are corrupted, one post with files but no instructions. please help me with this.
​Thanks,
WY.

Flash a stock rom from here (UCJK2 for Focus revision 1.3 / UCJK3 for 1.4).
Here's a flash tutorial.

Thank you very much for your help.. but some reason my mobile was not detected in the loader..everything was green but Start button is disabled and the mobile was not shown in the ports section.
Some how i am able to start it in format mode cancel and it went to magldr cmd..installed everything and this time works perfect.
Appreciate your help but i still dint get why start button was disable.

To "green" the port in the flasher, unplug the USB from your comp, wait about 2-3 seconds and plug it back. Just before flashing (after all are loaded).

As EnderPsp said u should always start the downloader first and then connect the phone in download mode.

i tried either way.. first attempt i connected mobile after loading the files as said in tutorial.. but start button was disabled and the mobile is not shown in ports section of the flasher..but it was shown clearly in system bar that mobile is connected and even safe remove was showing the mobile name. sorry to ask so many questions, its just in case it will be very useful for others in future.. thank you very much for your valuable replies.

Trying to flash Mayalsk update.img via GPS SD, not working / no recovery

I've bought an Android 6.2" HU with 4.4.4 and Quadcore 1.6ghz, 1gb ram, 16gb nand.
Google/Ebay search for Pure-Google-Android-6-2-Double-2 Din-Car-GPS-DVD-Player-Radio-Bluetooth-Camera
It's not branded. The vendor sent me a firmware for "AD-UN6202". MCU is TS901.151104. That's about what I know.
The firmware from the vendor is a bunch of files. The HU reads and flashes these just fine, when using GPS SD and reset. Files are:
root.tar, ramdisk.gz, recovery.gz, atc.upd, target.bin, rd_datazone.bin, 83XX_Preloader_realchip_sd.bin, data.img.ext4, arm2.bin, cache.img.ext4, data4write.img.ext4, databk.img.ext4, u-boot.bin, uImage, system.img.ext4.
I wish to put on Malaysk 4.4.4 rom, but it's not reading the update.img which i've stored on GPS SD. I've tried a bunch of different methods to get into recovery, to no availability.
So how to I proceed?

thx

Hi
i have same screen on my unit,i need your update rom,is it possible to share?
thank you

You have pm with link to firmware.
Firmware has some serious bugs. Radio starts randomly by itself. Settings are not saved after power cycle. Radio app cannot be linked into Car Launcher app. Radio app might save presets, same for EQ.

Dear friend, can you PM me the link of your firmware. I have the same MCU and try to modify core files.

Were you able ot root this headunit? If so, how did you root it? Kingroot and Kingoroot won't work for me.

i dont have this unit, I have a Joying, but I never got them to work via SD card, I always have to use the USB for changing the ROM

Even though the forum "seems" to support it, you can't embed images. You have to attach them, which means uploading from your computer.

Chinese Android Radio XYAuto 8227L YT9213A Firmware Update(help me please)

Hello all,
I am not a professional but still ambitious and would like to solve the existing problem
Since my English is not perfect, I use a translator, sorry if some written is not understandable.
Coming to my problem.
I bought 2 years ago from Aliexpress from a reputable seller an Android. 8227L YT9213A
From the beginning, the device was very slow or lost the GPS data.
original firmware was YT9213A_00009_V001_20200408

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
before the failed firmware update
As a result, the seller sent me a firmware "xyauto_ui1_9213A_full_8227L_demo-ota-20200517". I copied it to a USB stick (rar file not unzipped) and successfully performed an update via the radio menu "Android Update".
Over time, however, I noticed that the navigation "google maps " always crashed. also lost the gps data.
about the playstore to update the apps brought no success. the problem was in my opinion on the android system,
it was still slow and not fun at all.
I have now contacted the seller again and informed him about the problem.
he sent me a new firmware "gongban_YT9213A_ui1-hw-ota-v6.5.zip".
after some research i found the XY Auto firmware download page.
XYAUTO
file manager
file.xygala.com
there I found exactly the same firmware what the seller sent me.
I copied the firmware zip file to a USB stick and tried again to update the firmware via the radio menu "Android Update".
Unfortunately, an error occurred, I have repeated the process several times. tried different USB sticks but it always came to the same error.
I think that this firmware what the seller is not compatible with my device at all.
I have on the http://file.xygala.com site then a previous firmware and that is
"xyauto_ui1_9213A_full_8227L_demo-ota-20200523.zip" downloaded and copied the USB stick and again through the device menu" Android update" performed.
This time I noticed that it did not come to an update abort. it came the message 1 of 53 apps are updated, but at "23 of 53" it froze and the system was rebooted, then the installation continued "1 of 9 apps" are updated. Finally the message came, "Update complete".
then the system was rebooted but the startup screen froze, the touch did not work. the image distorted and after a few seconds the system was rebooted again. this phenomenon repeated itself again and again. so to say "boot loop effect"?
then i started to research on youtube saw some videos how the firmware was updated with flashtool. i wanted to copy it. I downloaded the "Scatter-loading file" from the firmware folder the seller sent me "gongban_YT9213A_ui1-hw-ota-v6.5.zip" ( but I downloaded the same firmware for PC update from the http://file.xygala.com site
downloaded) and loaded and thus tried to flash. the " preloader " in the first row was not activated. the hook was missing. manually I could not click either.
Then I tried to load the "scatter-loading file" from the previous firmware "xyauto_ui1_9213A_full_8227L_demo-ota-20200523" and flashed " Format All+ Download" it started to load at the bottom of the bar but then came an error message.
So now I think I have made things worse.
Now the screen stays completely black. Android loading process I do not see. I see short flickering but it remains black
The seller only answers when he feels like it and doesn't really help me.
It would be a shame to throw it away. I don't think it's a hardware problem.
Can anyone really help me from afar and give me a tip.
I would follow any instructions and try to revive the device.
thanks in advance and hope someone will help me.

Do you have a 'Preloader' file?
Dont do formatting without 'preloader' file.
You can only do a downloading without this file. I dont know why flashtool even let you do this step without all files included....
Im using this version: sp-flash-tool-v5-2112
Then get the 'preloader file and use with package 'xyauto_ui1_9213A_full_8227L_demo-ota-20200523' you've got. Do format wit all files included/selected.

hello guys i have this head unit and i really want to change the firmware .interface ugly and aux deosnt work no sound equilizer ....

hello, i have a chinese car radio ff-5000 8227L, i installed avg anti-virus, then i activated the screen lock via this antivirus, please how can i deactivate the screen lock ? THANKS

Brogotek MTK8667 Head Unit wont recover

Hi all
I have one of these https://www.ebay.co.uk/itm/384770479698 in my 2006 Merc. its a MTK8667 Android 11 based unit. FF_866X is the device name, i'm sorry I do not know the MCU
I was sent some update files from the seller https://we.tl/t-UeDC40i6Ul XRC-8667 升级软件 Q腾实UI多合一-国外-1280x720_v32_20220223
Upgrade steps
1) Unzip after downloading (only unzip once)
2) Copy the file to the U disk
3) Connect the U disk while the power is on
4) The machine will automatically upgrade
5) If the machine cannot be upgraded, you need to press RES and keep touching the display with two fingers
during the update process it copied the superimage ok but then something came up in red but it came up to a kind of recovery and said erasing... it then rebooted it gets to the car logo screen, before android screen then goes to a blank screen with the following in bottom left corner...FASTBOOT MODE and wont go any further
I have pressed RST then two fingers on screen until i get "detected" but all i get is the same fastboot mode again,
I have redownloaded and extracted the firmware and reformatted my usb drive to fat32 and tried the whole process again and tried in both usb slots but no sucess...what can I do?? is it broken??
I have obtained other mtk8667 firmware files 8667.bin and 8667.upd from this topic https://forum.xda-developers.com/t/firmware-junsun-v1-8667q-8g-128g-vhd-qled.4405475/ on this forum but I have tried many different ones and it just wont read the usb, still just goes straight to fastboot mode....is anyone able to help me I have messaged the seller but no reply
So far I have tried about 7 or 8 different firmware versions, the sellers own, some junsun versions, ossuret versions even xtrons versions(all in correct format of 8667.bin and 8667.upd on root of usb formatted to fat32 but it does not read the usb.
The usb slots are still working as I can plug my phone in and it charges but the unit does not seem to have a full recovery mode

I have messaged the seller (brogotek) on ebay but no reply as yet which is strange as they have always replied very quickly.
Do you think it is fixable? it was bought in April and ebay advert states it comes with 12 months repair or replace warranty
There just seems no way to get into any kind of recovery mode
