[Xiaomi Redmi Note 5 Pro Questions & Answers] Vitorvlv:
I have a Redmi note 5 pro, I was using a custom rom, but was experiencing some bugs so I decided to put another ROM in it, I already did this lots and lots of times and I always followed this procedure:

Reboot into recovery(TWRP), Transfer the ROM, GAPPS and MAGISK to the phone > wipe Cache, Dalvik Cache and System. > Install ROM, GAPPS > WIPE DATA > FLASH MAGISK > WIPE INTERNAL STORAGE > DONE.

Never had a problem, but this time idiot me was doing this at 5am, dying to go to sleep, and I started by wiping everything, without moving the files to the phone beforehand.

Well, apparently once you wipe the system the phone internal storage doesn't show up in the computer anymore, I didn't know that. I always thought that since TWRP was MTP compatible, it would always be a thing, welp.

I then thought of 2 solutions to this: I remember ADB sideload was a thing, and I also could buy a memory card, put the files there, and just load into the phone, bam.

Since it was 5am the memory card would have to wait, and I couldn't get ADB sideload to work, it would't recognize my device for some reason.

I then remembered fastboot existed, and weirdly enough my phone was recognized as a fastboot device on my pc. So I went, downloaded the correct fastboot rom from xiaomi website and tried flashing it using a official tool that they provide, and then tried again using a third party tool that also does something similar.

I was getting a few errors, and then in one of my restarts the phone just stopped showing stuff. It would still turn on, but it's just a black screen, no icons, no recovery, no fastboot, nothing. The battery icon when I put the charge in is the only thing that still shows up.

I already know the answer to this, but hope is the last thing to die, so, is it irreparably ****ed up ? Is there anything I can do? Is it even worth it sending it to repair services? (It wouldn't be Xiaomi, they don't have stores here in my country)

EDL

i´m pretty sure that at least EDL Method works, many tutorials on youtube. Search for "redmi note 5 edl method"
[Xiaomi Redmi Note 5 Pro Questions & Answers] Verity.:
Try to find something about edl mode as mentioned above. It might be your last chance to revive this phone, but you need to take the back cover to be able to find the edl pins and short them. There are many guides on the internet as well as on youtube. But before you try to do that, first try to enter the fastboot mode somehow, you may succeed, so tinker with it for couple of minutes.
[Xiaomi Redmi Note 5 Pro Questions & Answers] rasik107:
As you are able to boot it into Fastboot mode,

1. boot into fastboot mode

2. boot into recovery using "fastboot boot twrp-name.img"

You should be able to see your device in PC after booting in TWRP

3. format data.

(

If you are not able to see Internal storage of your RN5 in PC then,

1.boot in fastboot from twrp.

2. boot in twrp again using command above

)

4. then copy your files and flash them.

5. wipe cache/dalvik

6. reboot :o
[Xiaomi Redmi Note 5 Pro Questions & Answers] Vitorvlv:
As I said in the post

I can't boot into fastboot. Right now my only chance seem to be EDL mode, I'll give it a try as soon as I can.

[Android Head-Units] NicoApple:
Im looking for the same ROM. Let me know if you find some info. Also Im looking for the AirRadio App. so I can use a Launcher.

Thanks
[Android Head-Units] bitstra:
All relevant info about ROMs and flashing you can find in top header of this russian forum.

Look at the spoilers in the gray header layer and use Google translate to understand what is written there.

There are 3 ROM versions for the 8227L based head units. I downloaded and installed the oldest of the 3 (rooted and TWRP IMG included). Copy all files from the RAR to a flashdrive in root folder.

Turn off the head unit.

Connect the flashdrive to USB 1 slot of the head unit.

Turn on the the head unit.

The install process starts immediately after turning on.

It takes about 10 minutes.

When install process is ready, turn off the head unit.

Detach the flashdrive.

Turn on the head unit and it will boot with factory settings like a new device....

Note that there are also ROMs for flashing wit MTC flash tool downloadable.

But the versions for installing from USB sticks ( po russki - dla flashky) are more comfortable to install and I don't own a Windows pc. So this variant was my favorite method...

Regards and good luck...

Edit: if your unRAR program asks for a password for unpacking the RAR file, then use Eazy unRAR app from Playstore on your Android device - it ignores password lock in RAR file ;) ...

Edit2: the 5th gray spoiler in the top header of the Russian forum hosts the links to the ROM RAR files...
[Android Head-Units] fani:
The USB flash drive method didn't work for me, Device doesn't detect USB while booting up. I tried everything, connecting the test points, pushing reset button etc. to no avail.

SP flash tool does seem to work, I have tried uploading several available roms, only these three uploaded successfully,

full_8227L_demo-userdebug 6.0 MRA58K 1534513814 test-keys

Заводская прошивка под флештул от 09.11.2018 UI1 с переводом

20181224 TWRP ROOT перевод и эквалайзер от ноябрьской

but didn't turn on the device. Device turns on but I get a black (backlit) screen. What else is there to try?
[Android Head-Units] bitstra:
No idea, what else you can try :(

If you can connect a PC to headunit and flashed a ROM with TWRP, may be you can use adb reboot recovery and clear data and cache via TWRP?

Hope you find a solution to boot your HU...
[Android Head-Units] fani:
No luck with adb either.

seems like my only option is if I could get the exact ROM for this device and flash it. The seller was less than helpful, so Aliexpress refunded me in full.
[Android Head-Units] fani:
Received firmware files from seller, but its probably the update files, not the complete firmware. Unable to flash it via sp flash tool. (copy and paste the whole link until the .zip part)

Any ideas ???? my device is a brick at the moment, and doesn't recognise usb flash drive for updating.

[Android Head-Units] coffer:
Did you get your connection to the PC yet?

---------- Post added at 03:28 PM ---------- Previous post was at 03:25 PM ----------

Thanks for that, wow the memory dump is massive more than 4Gb! Did you use format and download or just download in the Flash tool? Do you know the files the scatter file took from the memory dump? So, you didn't use any files from the first download where you took the scatter file from? I'm still having a problem connecting to my PC may have to use the hardware forced (testpoint) method!
[Android Head-Units] fani:
You need usb male to male cable, attach it to usb1 on the device. but not yet connect to pc. Run the sp flash tool. and select the correct scatter file. Then run which ever function you need. after that connect the usb cable to pc while connecting these two test points (picture) with a small piece of wire to each other. After it is recognised and operation starts, you can release the jumper wire.

View attachment 4769616
[Android Head-Units] coffer:
Thanks, when I use the scatter file from the first download and put it with the files in the second download it only picks up the preloader file nothing else?
[Android Head-Units] fani:
Hi, Scatter file is only needed to make sp flash tool recognise the partition table on the device. no need to download anything via scatter file. press Ctrl Alt V , then go to Window and select "write memory". Set start address to 0x00 Use this to write Boot_1 , Boot_2 and User, to EMMC_Boot_1, EMMC_Boot_2 and EMMC_User respectivly. thats it.

I hope it helps.
[Android Head-Units] fani:
Hi, yes, I fixed it. Check the first post for details.
[Android Head-Units] ric69:
Thanks but for most of us , we don't have any USB recognition to pc (or android devices) there is any sounds when plug
[Android Head-Units] coffer:
have you tried the test point method yet, I will try it tomorrow or Monday?
[Android Head-Units] fani:
its just the equalizer. In non hifi, 180 switch doesn't make any difference in sound. and in hifi version, hifi needs alway be on to have decent sound output. Only difference in the files I shared, I think, the June update is for YT9217B and the May update is for YT9217C

There is no difference in performance either way. They both work fine on my unit, (installed via memory dump, and then regular update).
[Android Head-Units] fani:
Volume seemed low for my taste. Checked with MTK Engineering app, Under MTK-Hardware-Audio-Headset-Media-

Max volume was set to 88 (max value 160) I set it to 130 and volume improved much. (don't know any long term effects yet).

Note: there is no option to revert back to default settings, therefore change only what you need to, and always keep backup.
[Android Head-Units] ramnkc:
Can you share which setting you set in MTK audio? I tried everything still it sound so high for each first time load up. Maybe I need to flash the full firmware instead of ota update... Problem now is I need to flash back stock recovery for me to install full firmware. There isn't any TWRP flashable zip :(

And I found another bug is that my wifi speed really slow... With Bluetooth connected or non also same issues... My original firmware is working fine tho. Then my TIMA phonelink app unable to start each sleep... I need to reinstall it each time, bug on the no sleep mode :(
[Android Head-Units] lemmon:
Thanks... I will try to connect the aircon vent to the unit somehow

---------- Post added at 12:45 PM ---------- Previous post was at 12:38 PM ----------

Hi there

I have a couple of issues I would like to share :

I am still having issues with Waze... it is working fine when it is running but if Waze is running in the background some times it closes automatically... any idea why some applications are closing when they are are running in the background?

I have tried different versions but still same thing ......

Another glitch is that some times when a switch on my car, the unit stars with the multi window screen ( the android screen where you see all running applications ). I have the agama launcher.

Lastly with agama launcher, when I switch on my car, some times you see that the headunit needs some time to launch the agama launcher. It takes like 10 seconds and then it starts with the agama launching screen before the agama launcher shows in the headunit .... not sure why it is not instant .

Thanks in advance
[Android Head-Units] fani:
For the load up volume, I would try the volume settings under Car settings app. set all sliders at where you want and tick Set default box.

Wifi link speed I see about half of what I get on my phone. I have soldered external wifi antenna, as shown in the modifications link I shared earlier, which helps with signal strength, but speed is the same.

I tried Tima app, but I didn't like it. I have all the aps i need on the head unit, so didn't need the mirrorlink anyway.
[Android Head-Units] fani:
Have you tried other navigation apps? like OfflineNavigation, Sygic, or iGo primo? Sygic works well with agama's central widget. and I like it.

About glitches, check if agama has all the notification access it needs. sometimes disabling and re-enabling them helps. Also if there are more than a few launchers installed, it makes things glitch. I also noticed lag in agama load up at car startup. But after recent reflash with memory dump, and upgrade, everything seems more stable.

[Android Head-Units] lemmon:
Many thanks

Can you please remind me of the test points you mention in you first post for the memory Dump procedure are the 2 pins i shortcut with a clip?

Regarding the waze, I did not try any other navigator... waze gives me a lot of indications in the background ( police, danger, rain, etc) for the road and I consider it a must to have in the background while I am listening music...::
[Android Head-Units] fani:
Pictures in attachment.

I knew I'll be flashing more than once, So I soldered 2 thin wires (found in old desktop) to the test points, and brought them outside the unit.

the test points are actually "volume up" points, I tested by attaching a small push button to the wires.
[Android Head-Units] lemmon:
Sorry not sure to understand

Are you saying that if I press the volume up instead of the test points I will be able to write without opening the headunit ? Thanks
[Android Head-Units] yusriyusoff97:
Is there any rom support for my device here??? and how can i do custom boot logo since my car logo is not in the list
[Android Head-Units] fani:
no, I'm pretty sure touch buttons don't work until booted up. The internal test points are the contacts for a physical vol up button.
[Android Head-Units] fani:
Yes, try the usb uprgades I have shared in 1st post. MCU3.1 and 20190624 android.

Also check the link there for the boot animation page. you might find something useful there. or may be contact the op there. best of luck.
[Android Head-Units] cafsta:
I'm loving the 2205 updates as well as the 3.1 MCU...

I was about to throw in the towel with this unit and get rid of it but with the quick boot feature working now, I'm just loving it.

I'm using Carwebguru launcher so have the strange window opening sometimes when starting my car but it beats having to wait a minute for it to boot up.

Big props to the developers who are making out life better.
[Android Head-Units] yusriyusoff97:
Is it compulsary for me to follow the version like yt9217b only and cannot use other version like YT9217C?

Btw i dont want to change boot animation, it is just boot logo. I try to do in photoshop 1024X600 with 160dpi and jpeg format. When i try to select it, its just close the car setting and nothing change. Did you know where to locate all the internal logo folder in the head unit system? Thanks
[Android Head-Units] fani:
yes, with carwebguru, it happens sometimes. make sure the permissions are all correct for it, and remove all other launchers, or at least disable permissions for the other launchers.
[Android Head-Units] fani:
There is no difference in B or C, that I could find. I tested both. Only difference is in the equaliser layout. which makes no difference in sound IMHO.
[Android Head-Units] yusriyusoff97:
The boot logo corrupted and become like this
[Android Head-Units] fani:
With the quick start MCU2.8, the boot image and animation is not that relevant anymore. The unit starts with the UI home screen every time.

Tip for xyauto owners.

Found that we can change the RAM configuration from 1GB to 2GB for eg. if configuration has been changed after flashing different firmware.

I know it was possible to change with some adb commands, but I forgot what command that was.

So i found another method:

•You need to install some 'activity launcher' app.

•Open it and go there to the 'CAN Settings' app and select the '.SystemInfoSet' Activity.

•Select 'System Info Config DDR' option.

•Chose DDR1 for 1GB, DDR2 FOR 2GB.

•Reboot to apply.

Did it on my newer 2gb HU and it worked properly.

Also tested it on my older HU which I thought had 1GB of RAM, but now system info and hw info apps also shows 2GB of RAM and it use over 1GB sometimes, so I don't know if it's faked so good or it really was 2gb unit originally, anyway the system seems to be more efficient.

[Android Head-Units] moneta95:
Good morning, everyone,

I've been trying for a couple of weeks now to un-brick my YT9216C (bricked after foolishly flashing the preloader by mistake). I tried flashing the original preloader with SP Flash Tool, but I keep getting error 4032 S_FT_ENABLE_DRAM_FAIL.

I should mention that I have tried re-installing the MTK drivers by following various guides and trying various versions, and I have attempted the procedure from 3 different PCs, all without success.

Has anyone been in the same situation as me and knows how I can solve it? Here I leave some info of my model:

Model: YT9216C_AHD_00005_V004_20200724_HIFI

XY_AUTO: 3.4

CAN Pro: 3.1

MCU: 3.1

Translated with DeepL.com (free version)
[Android Head-Units] Emilson:
@moneta95 just try to flash your preloader using other scatter files, for example from xyaut yt9216 packages etc with 'format all + download' mode.

@molee899 there is no point in updating it right now, if you dont have any problems with Your headunit.(btw its not android15😅, it truly is Android 8.1 nomatter which update You choose)

You have quite new software 7.3.8 (of course there are newer ones like 7.3.9 or 8.0.1 but these are only small corrections in my opinion.)

Your version should already have an online update of the CAN database, which is probably one of the biggest improvement of the recent updates and 7.3.8 include newest xyauto theme pack as i remember.

Anyway seems that you may have some unusual model, may have used some different parts or configurations and your current firmware may be specifically dedicated to your version, xyauto updates are quite universal, you may lose some audio adjustments or other issues if you flash random firmware.​
[Android Head-Units] moneta95:
I tried flashing the preloader with Format+Download from a rom for the YT9218 (different model than mine, but strangely the only one that works). I then flashed the correct version.

I don't have a chance to try it right away but within a couple of days I will let you know if it worked.

In the meantime, thank you very much 😁
[Android Head-Units] molee899:
Thanks for your help, I installed the 9212a ROM, but recently I found a ROM whose format is bin and I couldn't enter the recovery, I tried touching one point and several points and... it didn't work, is there a way?
[Android Head-Units] moneta95:
Guys, I solved by flashing the preloader from a rom for a different model (YT-9218) with the Format+Download option. Afterwards I flashed the "correct" version. So I thank everyone! 😁😁

Now I have another problem, the buttons on the panel no longer backlight. I tried from the settings under "factory settings" but no way. Do any of you know any good method?
[Android Head-Units] Vivid Studio:
sorry but how to unlock the loop lock . i have this problem now
[Android Head-Units] Emilson:
A lot of configuration like button config, screen resolution, screen touch settings etc etc are stored in 'metazone.bin' file so remember to use your originally dumped metazone when flasing any package.

You can try to set your buttons in car 'factory settings' -> 'Touch settings' / or 'physical buttons study'
