My PC was able to recognise the Head Unit again by holding the two test points while connecting the usb to pc. After 2 seconds, it get disconnected again maybe because I have no power running on the ACC. (I left my 12V adapter at home). I will try again tonight when I get back. I was pretty sure I flashed the wrong preloader earlier resulting in this bricked state. The unit should boot as usual if the preloader is the right file. If any of you guys facing the bootloop like mine earlier (when turned on, the screen flashes and dimmed for a few seconds and keep repeating that sequence), please make sure you get the right preloader and install Mediatek VCom driver and have it updated so that your PC could recognise the bootloop/bricked Head Unit.

Connecting to computer with TP, but flash start only with read progress and after few second comes up dram error
[Android Head-Units] mylancerex:
so none of the files from bansy and blackangel works with your head unit?
[Android Head-Units] blackangel82:
Firmware from bansy is wrong and was damage my unit, my one is only OTA update not contained preload file. Need to find out right full firmware :( is on russian forum thread with software, TestPoint etc but can't write/speak in russian language :(
[Android Head-Units] Azmil2307:
Ok now my Head Unit is booting! Just follow exactly these step but flash only preloader 1st, than flash again all files except preloder. And make sure to select Format All + Download; https://m.box.com/shared_item/https://ezonetronics.box.com/s/zm10hsfv4rqijhtgu9ftfni300yg440m

But now my touch screen is not calibrating correctly... still trying to fix. But that’s just a small matter because my unit is alive now!
[Android Head-Units] blackangel82:
Which preloaded you chose I was follow stepguide and select the one in main folder not from scatter file. Anyway was try with both preloader files and is not working still getting error dram failed :(

For touch try to flash my OTA update
[Android Head-Units] Azmil2307:
I use the one in the main folder. But I flashed only that preloader. I unticked all other files. After that, I flashed for the 2nd time selecting all files except preloader. And make sure Format All + Download is selected before flash.
[Android Head-Units] blackangel82:
All time try to do it but getting same error :(

I was flash my unit with firmware from bansy, just replace preloader for the from main folder. After flash was restart unit but didn't comes up just black screen slightly highlighted. Was try to reflash but nothing, now is connecting with TP, in flash tool is only 100% Da send that's all after few second scones up dram failed no matter what preload file will chose or option with format or not always same dram error
[Android Head-Units] blackangel82:
Still nothing same error
[Android Head-Units] Azmil2307:
Did you release the Test Points right after it goes 100%?
[Android Head-Units] blackangel82:
Hi yes, after hit 100%, holding all time, just short press , with reset button without always same. What point you touch to GND, same as from my picture ?? Did you hold with reset button ( for me not making any difference). Tired changing drivers, is another white socket on board with GND Rx tx 5v 3.3v looks like JTAG, UART connector or another usb
[Android Head-Units] mylancerex:
really appreciate it if you could make a step by step instruction so we can follow exactly what you did..

thank you
[Android Head-Units] Azmil2307:
I just connect the two point together with a metal pin.. no GND, just the two point. No reset button. The unit not even on power. I use only pc, the motherboard of the android unit, a metal pin and a male to male cable.
[Android Head-Units] Azmil2307:
Sure, I will share the step by step soon in the 1st post. Wait until I get back home tonight:)
[Android Head-Units] blackangel82:
Was try to touch this two pins together without touching GND it is recognize by computer but is same problem is going up to DA 100% thats all :(

strange at this firmware was help you but was damage my unit, from the 1 post looks like is same as my one .

Will send this unit back for refund
[Android Head-Units] Azmil2307:
Sorry I was confused earlier. I did try to flash my unit a couple times today and all went successful! Actually I flashed all the files together once. I just change the preloader to the one in the main folder (exactly like the instructions). I just don't connect the unit to any power, just the usb to pc. Keep trying my friend. As long as you still got response from the unit, you stil have hope. Why don't you tell me your step by step in flashing first? Maybe I can help you. I'm trying my best to help everyone since I knew how hard it is to revive this unit.
[Android Head-Units] Azmil2307:
Ok need a few hours of testing.
[Android Head-Units] blackangel82:
Was follow exactly what was in instructions step by step, unit was connected at this time in car. Installation was successful.. after that was switch off radio disconnected male to male cancel and power in radio.
[Android Head-Units] Azmil2307:
Sorry I couldn’t really understand you. If you are having problem with radio (for example, the unit starts to hang and restart when you open the radio, you need to change the radio in Factory Settings).
[Android Head-Units] blackangel82:
Hi misunderstood, radio I mean a unit stereo not a radio as apk

Thats short video when I flash unit first time

https://streamable.com/a18vr

Unit is only highlighted, after flash stay same till now

But you can see as everything was done like is in instruction
[Android Head-Units] Azmil2307:
Ok you mean the flash was successful but the unit still won’t start right? I have a newer firmware (I flash this firmware on my unit successfully as well), if you want to try, I will upload soon.
[Android Head-Units] Celidar:
Touch screen calibration.

Hello guys!

How to call the screen calibration:

1. Touch the screen with five fingers and hold until the calibration window appears.

2. Car options, factory settings, 8888 code, enter (many options inside)
[Android Head-Units] blackangel82:
Will be appreciated if can upload please.

One more question you have flash just PCB disconnected of LCD screen etc. Right ?? I just open the back cover PCB still connected to LCD etc. Maybe worth trying disconnected everything before flash
[Android Head-Units] Azmil2307:
Yes, usually I disconnected everything. Only the motherboard connected to pc.
[Android Head-Units] blackangel82:
Will wait when you upload other firmware.

Regards
[Android Head-Units] mylancerex:
still need to use TP method or no need?

which pinhole need to be connected together? any pic?

thanks.
[Android Head-Units] Azmil2307:
Here you go my friend. Just load the scatter and flash format all + download. Hope you succeed. Actually your unit could still be revived as long as it lights up. You just need to find the right firmware.

https://mega.nz/#!FE4FHKAI!ALdd6JZYmWZz6VTgHvK9HTzakR25aBcATLxCgUZsYvg
[Android Head-Units] Azmil2307:
After click download on flashtool, connect these two points together;

[IMG="TP"]https://cdn1.imggmi.com/uploads/2019/1/29/a938138468ef4879d25b4acd1c4e2ad1-full.png[/IMG]

Hold and connect usb male to male to pc. When it started to flash, immediately release these two points.
[Android Head-Units] mylancerex:
can not see the pic of TP..

i tried to find "download" button on box.com account where you shared the file, and could not find any..

should those files be downloaded into local hardisk before flashing, or can work straight from box.com?

thanks
[Android Head-Units] Azmil2307:
I didn’t share anything on box.com. Maybe you are referrinh to other user. I upload my files on mega.nz
[Android Head-Units] mylancerex:
i think you did share on Jan 25 pg.4. post #40?

anyway, i have successfully dowloaded the file from bansy's link.

should i need to install the driver named SP_Driver_v2.0 before running the flash tool?

thanks
[Android Head-Units] Azmil2307:
Oh man I’m really sorry I forgot. Actually that link was from another user, I just shared it. Please download another firmware that I shared using mega.nz. Yup you need that driver. And Google for Mediatek Vcom Driver. That’s the only driver that could detect any bricked Mediatek devices.
[Android Head-Units] blackangel82:
Hi, this new firmware still same problem :(

Was try with just PCB, nothing change.

Yesterday was find out on youtube how to solve problem, in flashtool going to format tab and then pressing alt+ctr+v advance mode, you will see another two option normal erase & forcedly erase.

do format with Forcedly Erase , after that flashing full firmware.

But since i load scatter can't see this option anymore :( Guessing this person have modified flashtool.

It's the preloader wine as one of the forum members wrote . Could anyone describe step by step how to repair a preloader? Do you need to connect the test point and how to connect it?

[Android Head-Units] grzechu132:
Welcome ! I was able to solve the problem with my 8227L. I found a radio with a similar look, then downloaded the appropriate software for a computer, tried various combinations and finally managed it! I refer to the subject:

type in Google :

Обсуждение Головное устройство ML-CK1018 и аналогичные , на базе процессора МТ/АС8227L

Necessarily before downloading check the versions of your software, the number is important:

1) Android number (v0005_003_data)

2) MCU1 - HW-SWO (e.g., 1, 3.1, 9.1, etc.)

3) Amplifier (e.g. AC7315)

I downloaded the latest, compatible with my MCU, etc. I threw in

ATC_FLASH_TOOL, test-point method, because it could not be otherwise, format all + download , I chose scatter and checked each component, I clicked the download at the same time I connected the USB radio, after finishing - green bird, I connected the player to + 12V, the radio worked: )

Sorry for Google translate...

Tibor vagyok Magyarországról. Vettem egy ilyen rádiót is, telepítettem, hogy tökéletesen működött.

Nem adtam meg neki semmilyen képernyő jelszót, ez természetesen jött. Sajnos nem tudok hozzáférni a helyreállítási módhoz, mert a bekapcsológomb nem csinál semmit. Tud valaki megoldást a helyreállítási mód elérésére?

I am Tibor from Hungary. I bought such a radio, installed it and it worked perfectly. Then I replaced the car battery, and when I restarted the radio, it loaded android and asks for password. Tried many passwords, none of them ok. I did not give it any screen passwords, it came naturally. Unfortunately I cannot access the recovery mode because the power button does nothing. Does anyone know a solution to access recovery mode?

How do I go about hiding the standard task manager icon on the above task bar?

Every time I try to use my hotspot it does the "authenticating" then says "Authentication error blah blah blah try again later" I downloaded set edit and fixed the value from "5" to "0" & "-1" like another fourm said and It acts like it works but then says connected but no Internet. Please help me thanks in advance!! Can post pics if needed

I have a similar issue... in my case, whenever I start the hotspot it says "authenticating" and then resets the -1 to 5.... so obviously something else is happening... if I set it to -1 and then reboot, it comes back as a value of 1, even without trying the mobile hotspot...

Somehow or another I have managed to screw up my modem on my SPerry XT1766 (Boost Mobile).

I only get Emergency Calls Only radio signal, Settings app and bootloader info shows Baseband Not Found or Unknown.

I tried using RSDLite to flash

XT1766_SPERRY_SPRINT_7.1.1_NCQS26.69-64-10_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC

which contains the fsg.mbn and NON-HLOS.bin files, but this doesn't seem to help. I've tried multiple firmwares with multiple different modems and nothing seems to be getting my modem up and going. Back when I originally updated I flashed the partition updater also. I have no idea what to do now. I'm downloading the 69-56 version to try that, but I doubt it'll be any different. If anyone has any idea on what to do that would be great. Thanks

Try my baseband updater from this thread. https://xdaforums.com/moto-e4/moto-.../rom-stock-android-7-1-1-rom-moto-e4-t3885821

It will attempt to update your baseband to the latest version (M8920_15000.280.06.58.06R) from firmware build NCQS26.68-64-11. If this doesn't work for you let me know, I may have a solution.

Are you on Boost network? I've seen the radio off problem with ppl using a different sim.
[Moto E4 Questions & Answers] Knuxyl:
Yeah I already tried that but it jept giving me an error saying unknown command [ ]] or somrthing along those lines. i looked through the script and didnt see any typis. i think your NON-HLOS.img is different format than the NON-HLOS.bin files found in the stock firmwares, plus it's much larger. Anyways, tried a fastboot flash the modem with it and that didnt work either.
[Moto E4 Questions & Answers] Knuxyl:
No I am not on a boost network but this problem goes more into firmware than network compatibility because the bootloadet itself isnt even recognizing the baseband. For the record I am still using a CDMA network like boost (Verizon)
[Moto E4 Questions & Answers] Knuxyl:
Also as an update, the 56 version didn't fix it either
[Moto E4 Questions & Answers] madbat99:
The latest update did that too many people. It won't work with a different sim. The radio will be off.

I bet if you put in a boost SIM, it would pop right on.

They changed something in the -8 firmware.

One guy building ROMs (not here anymore) made some changes to his build that got certain networks to work on his ROM.

He never got the chance to share exactly what he was changing.

It seems that if you booted the phone ever with the original sim inserted, it tripped a qfuse (of sorts) and it seems they have added a way for that particular reading to turn off the radio completely if you're not using one of their SIMs.
