Yes there you go. You have an unlocked bootloader so now you can flash the ROM using fastboot mode.

Download Xiaomi Redmi K40/POCO F3/Mi 11X Engineering Firmware ROM

I have also attached the QCN file for the phone to restore IMEI.

Please PM Kevin mitnick and he will help you out.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] nkkrishna:
Thanks for qcn file. If I go with flashing the engineering rom do I need to root the device.? Do you have detailed steps.??

Because if I go with qcn rewrite steps, any way I have to root the device.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] mvikrant97:
Please flash the ROM as you would flash normal fastboot ROM.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] L8ter:
Let us know if you got it fixed.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] mvikrant97:
That's why I love the XDA community with no monetary benefits in sight but they care for each other.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] nkkrishna:
Sure, i am trying to get help from Kevin mitnick. I did the following

1. I have temporarily rooted the device using magisk

2. As per his recommendation, I am using this tool to open the diag port and update the QCN file.

3. I am getting following error using QPST and QFIL Tools

QFIL Error:

Not sure, if i am missing something.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] nkkrishna:
Can someone help me on how to proceed further
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] L8ter:
As far as I know you need to have an authorized Xiaomi account to be able to use QPST.

That is why I told u that you need a guy with an authorized Xiaomi account who can do the flashing for you.

You can search for these guys on the internet or on Telegram.

Costs from what I read 15 to 20 € wich is not that much for a working device.

I'am not promoting paid services here on XDA, just sharing my experience.

I'am only aware that it was possible to fix on older devices than the Poco F3, on older MIUI and Android versions.

And I still hope that i'am wrong bout what I'am saying and you get it fixed without having to pay money for a fix.

But I never had that issue on Android and so i'am not able to help you.😔
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] mvikrant97:
He may use the tools like Xiaomiking tool and Xiaomi Fire Tool both which are paid tools.

Yes we don't promote paid tools here but the thing is we need to fix the device somehow.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] nkkrishna:
Update : The phone turned-off because of low battery (i didn't notice this, as i was busy with my work). I charged the battery and when i turned-on, it started showing the mobile signal and IMEI/baseband. Not sure how it came again, But it went away again after a day....

What could be the reason??, the issue looks to be intermittent. But i cannot use this as a primary phone as the imei and baseband can go away anytime.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] mvikrant97:
Seems like a software issue. Is it running stock firmware?
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] nkkrishna:
Yes, on Miui13, A12
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] mvikrant97:
Have you restored QCN?
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] nkkrishna:
No, Note yet, i was stuck. You can refer to my previous message on 9th Mar with screenshots....:cry:
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] ApexPrime:
Try flashing on the communications port (com1). Also, I read somewhere that windows has some driver problems so it's better to do it on linux. You can dual boot it or use virtual box or some other virtual machine software.

Is your problem solved? It just so happens that I experienced exactly like you, can you tell me how to solve this kind of problem?"
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] nkkrishna:
Yes problem is resolved. My friend helped me.

He did install/ did a

FYI - Temporary root did not help.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] tempaone:
Hello,

My sisters Poco F3 just randomly lost its IMEI and Serial Numbers.

Her phone is stock and has not been tampered with.

when emailing Xiaomi support they asked to provide those numbers which should be on the box but she no longer has the box, and the receipt provides no information.

Is there another way to get either numbers?

does the service provider keep a log of the IMEI numbers?

Any help will be appreciated
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] noobaliothuser:
You can try logging into google "find my device" app through same google account of her , click the device icon there it will show both imei's
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] tempaone:
Thank you so much!

It only showed one, but she only has one sim connected to it. Hopefully Xiaomi can now get this sorted!
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] noobaliothuser:
try draining your device battery fully untill it is switched off , then let it rest for a moment , charge it and turn on after half an hour and see if imei is back ,

or visit the service centre and tell them to flash it through EDL with the latest miui ;)
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] noobaliothuser:
can you explain how permanent rooting brought back your baseband ?

i am facing the same problem as yours in screenshots above : "checking for phone connection" even after selecting the diag 901D
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Zinnz:
Is your Sim card detected when your phone is showing no imei and baseband?
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Rstment ^m^:
what software? This is hardware fault 100000%

Most likely the modem chip got detached... it requires resoldering if that's the case - reflow is another option, but I wouldn't even bother with ( It's gonna work temporarily at best , then it'll detach again )

That would explain why it suddenly stopped working altogether...

If under warranty send it over... if not rip , the phone is not even worth 100$ on the 2nd hand market , keep that in mind
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Zinnz:
No sim detected/unknown imei/unknown baseband seems to be fixed with FW 14.0.7
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Yawar koka:
Sir i tried to restore qcn in diag mode , qfil umt and other tools detect the port successfully, but when i try to restore qcn , QFIL shows "checking for phone connection" as its unable to access port somehow, Umt also gives error : "Port open failed".

if it had to do with windows drivers then backing up and restoring qcn on other qcom devices wouldn't have worked then i guess
[Xiaomi Poco X5 Pro] Miri_meow:
Hi guys,

I'm not a developer but after hours and days of searching online to no avail, I hope you can help me.

I have been using my Poco x5 pro 5G for a few days. Noticed battery draining way too fast. As I tried to diagnose and solve the problem, I tried completely limiting background activity for the battery-eating apps, that showed as such under the "battery" section (Facebook, WhatsApp etc.).

However, even after doing this, these apps are *still* running in the background! Some of them, in addition to Facebook etc. - are apps I haven't even opened at all for the last few days.

Each time I enter the battery tab and see what apps are running - even if I do this say 3 times immediately in a row - new apps keep appearing, ones I haven't even opened, alongside ones I actually manually limited to no background activity at all.

Please see photos attached.

So frustrating. Why is this happening? What can be done about this?

Thank you!
[Xiaomi Poco X5 Pro] scorthyn:
Use universal android debloater to remove most apps coming with the phone. In my x5 pro it removed 62 packages and my battery on normal use lasts about 2 days
[Xiaomi Poco X5 Pro] Miri_meow:
Thanks for your reply. I already did this (however, manually), removed many apps. And the problem persists.

Also, this doesn't explain apps still running in the background after I completey minimized their activity.
[Xiaomi Poco X5 Pro] zagarol:
It works without root? There is any tutorial or so? After 6 years with a rooted device and costum roms it's a little desperate to have the stock miui with all the junk in it 😅
[Xiaomi Poco X5 Pro] kingmi.hs:
1. Change DNS in setting to DNS.google

2. Install Adguard (full app) from adguard.com

Have a nice day
[Xiaomi Poco X5 Pro] Miri_meow:
Hi,

Can you elaborate/explain about this?

Thanks.

I want to disable some useless apps too but I'm not sure which onces
[Xiaomi Poco X5 Pro] Miri_meow:
It's better. But I'd still expect more from a new phone. I could easily end the day with around 20%. It's fine, but i'd expect better from what I've read about other users' experience with this phone.

HI all!

I have an erisin head unit in my vw golf and started acting up so i ran a reset. Still had the same issue so ran a 2nd reset. Still same issue.

Not sure how realistic these announcements are vs "marketing power-point based products", but it seems UNISOC has been announcing at Barcelona MWC more focus on Auto Chipsets. In particular from their Twitter account:

View attachment 5855787

Also, one outlet covering diverse Chinese MWC announcements in a note published:

"UNISOC will focus on displaying the first 5G smart cockpit chip platform A7870. It will also display a 4G car chip solution A7862, and an eight-core 4G car tech chip solution A8581. These products are currently entering the leading car group. In 2023 and in the future, UNISOC will further increase investment in automotive electronics."

The 7862 we know for years (and the 8581 is even less powerful) and that is why most probably they were branded in a more "legacy way" (4G)... but the fact that they (it seems) decided to dedicate some real-state of the stand to Auto solutions seems promising

Yes, I know, it might be ages until FYT or somebody else actually embeds this in a product... but the FYT-7862 has been around for 2.5 years already...

Has anybody heard anything on this?
[FYT Android Head Units] laoyang88:
6nm. 8-core design, including one 2.7GHz A76 large core, three 2.3GHz A76 medium cores, and four 2.0GHz A55 small cores.The CPU computing power is 93K DMIPS, the GPU uses NATT 4 cores @850Mhz, and has 217 GFLOPS floating point computing power; the NPU computing power reaches 8TOPS.Chinese semiconductors have broken through the blockade of Dutch lithography machines
[FYT Android Head Units] maxiauer:
Well, if the device is really coming, these are AMAZING NEWS !!! And way faster than what I expected. But I haven't found where to buy it yet

While it might look like there's little difference between A75 and A76, the truth is that A76 is not an evolution of A75 but a start-from-scratch (or "clean sheet") design. Also the A76 (although A75 also had that capability as well, I believe) uses a "more recent", more flexible way to arrange the cores and split tasks among them (DynamIQ vs big.LITTLE for the tech folks) (vs previous PX6, PX5, PX30, FYT 8581)

OK, OK...I know, "maybe" is "too much" of a CPU for a head unit mainly used for maps and music :p I would not recommend a recent buyer to update their heads-unit. But for people like me with a PX5 that is SCREAMING !!! for a replacement (too slow) these are great news.... now the HeadUnit will last longer than the whole car

I hope this CPU/Chipset gets paired with a good quality DSP and that they put some love on the circuit design to avoid noise being induced in the audio path or in the mic. I have no experience with the FYT units, but the MTC-xx were quite terrible on mic quality and prone to have noise issues on the audio side.
[FYT Android Head Units] marjanoos:
I think current UIS7862 delivers more than enough of power for those devices. I would rather expect other improvements instead.
[FYT Android Head Units] Clandaries:
I think even the UIS8581 feels fast enough for a head unit.

But better to have than to need like we say in Germany :)
[FYT Android Head Units] maxiauer:
As I said... I wouldn't upgrade to this if I had a recent unit. But my PX5 was a flash a few years ago until it wasn't anymore. Whether we like it or not, the OS and even the "normal" apps become heavier with time. So this unit is "future-proof" as much as tech can be future-proof these days.

But yes, I'd also expect some other improvements... maybe a better screen, QLed based to increase brightness in sun conditions
[FYT Android Head Units] marchnz:
It's not the processor that matters - its the software that matters. The chinese have year on year copied and brought with it the same bugs.

You can have a processor that's light years ahead, give it massive amounts of RAM, it won't matter...
[FYT Android Head Units] laoyang88:
Hardware will be constantly updated. The software depends on the level of each manufacturer. It can never keep up with the speed of hardware development. Just like buying a mobile phone, if you want stability, you can only buy an iPhone.
[FYT Android Head Units] surfer63:
Ah, you mean the iphone 12 that sends way too much radiation being bad for your health. So much even that health organizations warn you for it.

Or the new iphone 15 (Max/Pro) which was said to fix the "flare" issue in the iphone (Max/Pro) 14 lenses, but doesn't do that at all. It is just as bad as it was on the iphone 14.

Please do not compare phones (iphone, Samsung or whatever) with these buggy Android units.

And if you do, you should also mention that you can buy 4~8 units for 1 iphone. You get what you pay for. And when you look at my mentioned examples that is not even the case.
[FYT Android Head Units] pstrawder:
This seems to be the official SoC page from Unisoc https://www.unisoc.com/en_us/home/TQCDZ-A7870

It seems to really provide a decent performance bump. Looking forward for GA, but I guess it is going to be next year.
[FYT Android Head Units] marchnz:
Software....
[FYT Android Head Units] surfer63:
For me the only benefit would be that they finally support Android Automotive.

This does of course not mean that FYT will do that.
[FYT Android Head Units] pstrawder:
My guess this is not only on them but also on Google. AAOS is more restrictive than AOSP.
[FYT Android Head Units] marjanoos:
M7 is the one of the new devices. In specs apart the SoC and memory nothing has changed.

You can even buy a device with 512GB of internal memory. Wow. I've heard the story that there's a man on the earth who filled the whole internal storage of 128gigs HU.
[FYT Android Head Units] marchnz:
Make no confusion "M7 is NOT the new device."

The "new device" is an FYT based device from factory (type = 116?) With revised board (?) and a xxxx by xxxx display. This particular seller calls it "M7".

Can you measure the dimensions on that? The ones I saw in the listing are all about 2mm longer than the head unit I have here. Would be a pain if it didn't fit my existing frame. (9" model).

I think my current unit is 228mm wide, 130mm tall.
[FYT Android Head Units] j0hn83:
Interesting to see that the IYING 3D units have the 360 chip preinstalled.

$286 for 12gb+256gb with 2k screen and 360 chip. That's a really good price from LEROAADZ.

Over $100 cheaper than what Mekede wanted, probably with no 360 chip.
[FYT Android Head Units] anginx:
Mekede M7 Plus indeed has 360 support and I can confirm it’s in settings.

https://xdaforums.com/t/new-car-focused-unisoc-chipsets.4562259/post-89263810
[FYT Android Head Units] j0hn83:
I know it has support for it, but you usually need to pay them to install the chip.

I have 360 options in the settings on all my FYT head units but none have a 360 chip.

I've never seen a manufacturer install the chip without you asking/paying them to.

On the 7862 you can check if the 360 chip is present by looking at the 3rd line of the System Info screen (marked in red box in my image). It might be similar on the 7870.
[FYT Android Head Units] anginx:
Ah, I didn’t know, it’s my first head unit after years debating with myself.

I checked and mine doesn’t have a 360 chip and personally speaking, it’s not something that I’m interested in.

Did anyone already unpack the payload.bin using "payload dumper" or using "Android Image Kitchen" (preferred), modify the files (optimizing, rooting) and recompiling them? Maybe/Hopefully sign it with the test keys, and then flash it?

Has anyone got a version of documents ui APK that runs on this Android 13? I have a couple apps that want to use it for Files access. I've tried several from Android 10 up to Android 14 and most of them crash immediately. Some don't crash right away but are still useless.
[FYT Android Head Units] highlandsun:
They said they gave me the 360 model as compensation because I paid for the 12GB unit and it was out of stock.
[FYT Android Head Units] surfer63:
So also the 6318_1.zip itself. I could not find any signature.

And the erofs file system is indeed a pain in the a**, but manageable.

Then I leave it from here as I don't have a 7870 anyway.
[FYT Android Head Units] gordgelin:
both payload.bin and 6318_1.zip
[FYT Android Head Units] j0hn83:
Perhaps @gordgelin can comment on whether you can tell if there's a 360 chip from the system info on 7870? He has a 360 unit.

Oh I definitely have the chip, they also sent me the 4 cameras.
[FYT Android Head Units] W.West:
I have Mekede 7870 one which doesn't have 360 chip. It's 6gb+128gb one.

By the way, the latest Mekede firmware looks like the picture below. The navi bar has been replaced with the same one as the one on the M6 3D.
[FYT Android Head Units] Matt Devo:
perhaps I'm missing something, but with the removal of the capacitive controls, how is one supposed to adjust the volume if no steering wheel controls? I know it can be done via the notification menu, but that's hardly an option when driving
[FYT Android Head Units] highlandsun:
Yeah, these units would be too impractical without SWC.

I'm a bit disappointed that none of the CANbus adapters I've tried recognize the Voice button on my SW control pod. Also none of them support clock setting, which the factory Sony radio did.

[FYT Android Head Units] highlandsun:
Where did these come from? Wondering if there's any newer Iying version yet.
[FYT Android Head Units] W.West:
Someone shared it to others online but I don't know if it's against forum rules to give credit where credit is due with certain websites.

There are newer firmwares, IYING with the date of 01.17 and Mekede with date of 01.19.

I'll share it from my onedrive.

Microsoft OneDrive

1drv.ms

Files are

iying_ui_7870_2000x1200_-_20240117-he_2024-01-17_0611.zip

MKD+7870_UI2_2000x1200_国外付费语音_20240119_lzp.rar

Currently it appears that Mekede has prevented their UI from running on 7870 devices from other manufacturers.

If you install Mekede firmware on IYING, the launcher will not work, so it's best to stick with your device manufacturer's firmware.

The latest system date of Mekede is 2024-01-16, and the navi bar of Mekede M7 Plus has been replaced with the one used on M6 models. I haven't checked with IYING one.
[FYT Android Head Units] maxiauer:
With Voice button you mean the one to activate hands-free dialing? In several cars, all the phone-related keys (Voice Dialing, Pick-up and Hang-up) are not connected to the CanBus but are directly wired to the Bluetooth box. It's basically one cable (as it is a resistive system, depending on the key you press the voltage drops a specific value). If you find it on your car schematics, you can connect it to Key-2 cable in the unit and then program the keys. That is what I did with mine (2012 car, analog steering wheel buttons)

Hope this helps

It strikes me that all presented UI styles are for left-driving cars with the big navigation screen on the right closest to the right-side driver.

I know that 2.5 billion people do live in left driving countries, but where does that leave the other 5.5 billion people?

And knowing that currently nobody can modify the launchers, it would be a big no for me.

Or install Nova launcher or something else.
[FYT Android Head Units] W.West:
It could be a disadvantage for people who want to use the pip screen on the left of the UI. I'm getting used to M7 UI now but I wish there would be launchers with different layouts to choose from. Currently I can only choose the theme color.
[FYT Android Head Units] highlandsun:
I thought there was a setting somewhere to flip the layout, but can't find it now. Must've been in some other launcher.
