I see /data is busy. That's not good. I had the same problem once. I think I had 'use rm -f instead of format'. Have you checked your TWRP settings?

Or you do a advanced wipe and change FS to ext4 and reboot to recovery.

Uploaded LOS 14.1 file to androidfilehost and changed link in OP.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] iHusky:
You must

FORMAT

Data after you install CM 14.1 firmware, then you can install LineageOS and SailfishOS. I had unknown error too when I flashed SailfishOS but I can boot into system. Now I backed to android, because there is no good music app like Google Musisc or VLC on SailfishOS :(
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] zahidhasanzahid:
yes.i followed the exact instruction. i wiped dalvik/ART cache, system, data and cache before installation process. then first i flashed cm14.1 +los41.1 together. then selfish os.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] PiggZ:
If all you did is wipe, then that is wrong, you have to format /data to remove the encryption
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] PiggZ:
If you do an OTA today, you should get one new package, geoclue-provider-hybris, which will fix the missing satellite info from eg messwerk.

You as oldskool Sailfish OS user back to Android? Unbelievable! I understand it however. The lack of certain Android stuff gets irritating by time.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] iHusky:
No, I`m not "oldskool" SailfishOS user because I used this OS first time on my Xiaomi Redmi Note 4 and the one reason which keep me far away to use this OS is a fact that I need Google Music because I don`t want create playlist and change metadata of all my songs library, because it will take too much time. Ahhh and I need my bank app (ING Bank Mobile)
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] dreamofdeath:
as a ported OS , sailfish on mido is not perfect.... lack some features (Android Support mainly). in my opinion sfos on mido is the best compared to other device. because off that I dualbooted my mido so we can switch between sfos and miui easily.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] rudge79:
It's true off course: Piggz has done a great job on the mido. Probably the best Sailfish OS experience around the non-native supported devices. Regular updates. All great!

The lack of certain Android apps is because of the Sailfish OS platform and ecosystem.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] PiggZ:
If you try, you can have android support...but, when you use a sfos port, u should know what you are getting into
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] PiggZ:
What other devices have you tried?
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] dreamofdeath:
I used sailfish on 4 devices

1. Nokia N9 Lankku

2. Xiaomi Redmi Note 3

3. Xiaomi Mi 5 Prime which stuck in Language Choices at startup

4. mido
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] rudge79:
Can someone provide me a working platform_extraenvsetup.sh file?

I think it's the key to a working Android support.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] Polis4:
I'm on android 8 Oreo custom rom. I would like to install sfos. Have I to flash firmware.zip first or it's not needed? Thanks a lot.

OK, all done. Is there any file explorer application in Jolla store?

[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] andrea2107:
perhaps this? https://drive.google.com/file/d/0B825SMyajjViQTRNeGo5WlBxN0k/view

it comes from a nexus 4 so it needs to be adapted accordingly ( add mido specific stuff and 64bit libs )

also afaik we need a nougat-compatible alien dalvik build... good luck finding one

still, I'll try as soon as sfos adds fingerprint support... i will tell you guys if I succeed ( i won't share how to do it tho.... )
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] PiggZ:
Yes, several. Also some more on openrepos
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] PiggZ:
pretty sure you just have to change the soc number to match, eg 8953
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] rudge79:
Ok, but we have a nougat 7.1 cm 14.1 base then what use would an old Alien Dalvin be?

I like to port it from Sailfish X but I do not quite know how at the moment.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] PiggZ:
an old alien, with 4.4 compatibility, would allow eg whatsapp to run, and many more android apps.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] rudge79:
So this weekend I've got some time left because of the long weekend ahead. I'll give it a try then.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] dreamofdeath:
must try....

Edit.... i had change platform_extraenvsetup.sh and did like in tmo but aliendalvik.servise fail to start .

I add attachment from aliendalvik.service status and journalctl
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] andrea2107:
according to what I've read,your best bet is using an alien dalvik build from a similiar chipset.... perhaps the one for xperia x ( sd 650 ) could work
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] iHusky:
But is too hard to find this version of alien dalvik

Had you updated your sailfish ?

Did version --dup in terminal (devel su level)
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] Polis4:
thanks sir, i'm newbie on SFos. in OP may link of repo not working. can you help me how to do the update? thnxxx a lot
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] dreamofdeath:
Make sure you connect to internet.

Edit /usr/share/ssu/feature.d/adaptation-community.ini with url http://repo.merproject.org/obs/nemo:/devel:/hw:/xiaomi:/mido/sailfishos_%(release)/

1. Set password for root access in setting developer mode with your favourite .

2. Open terminal enter root access (devel-su) , the password is same as you created in developer mode

3. Type ssu re 2.1.3.7

4. Type version --dup

I add atchment to help
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] Polis4:
Hmmm, i have already installed 2.1.3.7 from the beggining..

[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] dreamofdeath:
You must update repos to make video recording work

Sorry sir I can't help . I'm not familiar with Linux

Probably not or the file is in use.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] :
Not really in Sailfish OS right now but if you know your device IP you can just type in terminal "ssh IP.of.your.device", enter, and you are in.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] rudge79:
Ok, so I've installed aliendalvik. When I do: systemctl start aliendalvik

I get an error from aliendalvik.service.

Piggz: any ideas?

---------- Post added at 10:33 PM ---------- Previous post was at 10:21 PM ----------

I have the same error.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] iHusky:
I don`t think that PiggZ help us, because use of alien dalvik is illegal.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] Polis4:
ok, i edited adaptation-community.ini succesfully (with new url), but when type version --dup give me an Error: File ' /repodata/repomd/xml' not found on medium 'http://repo.merproject.org/obs/nemo:/devel:/hw:/xiaomi:/mido/sailfishos_%(release)/' .Any solution? Thanks
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] rudge79:
I would flash the PGZ 27 zip again. Probably some little error in your file caused by misspelling.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] dreamofdeath:
Sorry I forgot that the new update is in testing level so the change the URL from devel to testing.

The right URL must be :

[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] Polis4:
thank you my friend, i'll be waiting! plz inform me about that.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] PiggZ:
from linux, with a usb cable, you can telnet into the device at address 192.168.2.15, port 2323 (may work in windows, but i dont use it, probably needs usb net drivers)

You can also ssh into it via telnet, after installing developer tools from settings.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] rudge79:
Thanks. Easiest way I find:

Within Linux type:

ssh nemo@192.168.2.15
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] PiggZ:
yes, and then use devel-su to get root

Hail Sailfish

Hi,

So I have been using a Jolla C all this while. But unfortunately a few of the hardware components broke, blame my rough usage and yes, I did disassemble the phone multiple times. It fell from my hand multiple times thus breaking the screen and ear piece. And with the recent fall the camera stopped working as well, the PCB connector got loose, I can get it to work, but unreliable.

I was thinking about moving to Sailfish X on Xperia, but then, on mer wiki I found that Redmi Note 4 has almost all the features working properly and Xperia X was no where to be found to buy. I read through the whole thread and was amazed to find the pace and the way the project progressed till now, kudos Piggz! So great to see a stable port by now and the support. Glad to find new sailfish users as well using it and loving the experience on it.

I am gonna order a Redmi Note 4 Mido in a day or two. Wanna join in you guys and finally use SFOS on decent hardware.

Oh, by the way, how is the battery life with aliendalvik running?

Thanks again Piggz and all other porters. :good:
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] dreamofdeath:
no support alien dalvik for mido ?
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] rudge79:
Maybe we can start a poll how many Mido Sailfish OS users want to buy Alien Dalvik and Microsoft Exchange support from Jolla for eg. $25.

I think the Mido is more capable of running Sailfish OS then Xperia X (suzu). The screen is more suitable for instance.

Piggz has run all the way and this Mido Sailfish port is as good as it can get. Now it's a dead end without Alien Dalvik.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] andrea2107:
You know,There are legal alternatives to Alien dalvik,you should try and get that working

I am still waiting for fingerprint support tho xD
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] lal883:
Yes, I know, no porting and configuring support. The question was intended at people who managed to get it running though.

Anyway, what is the general battery endurance of the device for decently heavy use case? I have a feeling that it is better than running Android.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] iHusky:
anbox is still on dead end, last changes are from 16 November, so I don`t think that someone still develops anbox.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] rudge79:
Battery endurance is much better. Location tracking by Android and apps is nearly off. 'Other communication' between Google servers is less.

Because of more privacy less data is transferred.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] faiizaah:
Hello... I interested with this sailfish port for mido. I have one question, can I update sailfish to the latest 2.1.3.7 in marshmallow based or I must update to nougat based ?

[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] rudge79:
Bingo, you have got the one million dollar question! Right now Sailfish OS without Android support is a dead end. All ported Sailfish OS have this 'problem'.

Better put: it's a lack of functionality. Because the Sailfish OS ecosystem is too small.

A real solution isn't there. Everybody's hoping something or someone will make it happen... One day. Till then; install Android.

if someone would have to do a video tutirial video for Dual Boot?
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] lal883:
People are at work man! I met a developer last day who is working hard to get Anbox working properly on Sailfish OS ports. It is not just one person, but many are. He admitted it to be not quite easy. Rest assured, developers are working and will continue to work until Sailfish native application ecosystem matures enough. All we could do is support them in all the possible ways we can or learn and join in. If there is enough time to spare, the second option, being a part of porting, would really be a great thing to do.

On the other hand, I am still waiting for my Mido to unlock. It is unfortunately stuck at 99%, "account not bound to device" error, while trying to unlock with the mi unlock tool. It has been more than four days now. Will wait a day or two more and try to create a new account if it doesn't work again.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] iHusky:
because you must wait 3 days after you send messages for unlock. I know that is not easy to port anbox but from 3 mounths I don't see any progress. But on ubuntu touch anbox work.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] LongLiveRem:
Thanks for port! :)

I did somewhat of dual-boot with LineageOS without glitchy DualBootPatcher, as it never works for me(breaks primary LineageOS).

I did a patch to initscript(gist.github. com/a1batross/1bd0b26c2407dc6688041b28e85868df), which allows me to boot Sailfish OS from SD card.

At first I backed up my LineageOS boot.img with TWRP. Then unpacked all data from .tar.bz2. file from ZIP. And patched /init from hybris-boot.img and flashed it. Works nice, but sdcard I/O is very slow(it's just my 4-year old SD card, lol).
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] PiggZ:

[MENTION=455718]PiggZ[/MENTION] did you read my message about anbox and ubport on tweeter?

When we can expect anbox too or ubport?
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] lal883:
Oh yeah! :D

Yes, I did. It has been a day on Sailfish OS on Mido now. Here is what I think, moving from a Jolla C.

It is amazingly stable and feels no strange. Thanks a lot for the great work PiggZ :good: All native applications that I tried are functioning smooth and much faster on this capable device. It is a treat to experience SFOS on decent hardware like this.

After the installation I did a version --dup. The repo was pointed at testing when I checked, so did not change it to devel. When I tried to play videos from gallery none started. YouTube in browser played no videos but a green screen and voice. Couldn't figure what caused that. And when I checked 'top' in terminal, a process called ksmd is always utilising 10 to 15% cpu, is that normal?

User experience is great. Although some times I experienced sort of friction in user interface transitions, especially when swiping down in events view to show the shortcuts or when pulling up the app drawer. It was smoother in the Jolla C, but I am certain Jolla did massive optimisations to make it fluid in the official devices.

Interestingly, I noticed that the UI transitions were equally fluid on Mido when I swiped while playing videos in Kodi.

I am sticking with Sailfish on Mido. Thanks a lot again for the great work PiggZ and every other porter of SFOS. You make this fun and awesome.

Will report back further about anything I come accross in coming days as I further get used to my new daily driver.

Edit: Sorted out video playback in gallery. Going through the previous pages in the thread, installed gstreamer1.0-omx and that worked.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] PiggZ:
Brilliant, thanks for the feedback (and not complaining about lack of android support ;) ... yes, iwas going to say install gst-omx, i'll look to see why its not automatic. gst-omx should also fix browser playback and allow camera recording ... but sometimes it seems like camera video recording isnt great...sometimes the recorded videos dont play back in gallery, but do when i copy them off and use VLC.

What do you mean when you say 'playing videos in Kodi' ?

Please report bugs to the github droid-config-mido package as per the first post.

Any possible possibility to dual boot this ROM as secondary with dual boot Patcher?

If yes then let me know how, step by step!

---------- Post added at 01:06 PM ---------- Previous post was at 12:46 PM ----------

Here is the process:

1. On your current ROM, boot into TWRP and do a factory reset!

2. Wipe everything except external storage!

3. Then flash cm14.1 firmware and format data (type yes to format)!

4. Flash cm14 ROM and then flash Sailfish OS WITHOUT WIPING

ANYTHING!!!

...Done!

I have encountered with some strange problem.

SFOS for some reason forgot my account in Jolla. So I tried to log in again, but it keeps saying me that my password or login is not valid, although the same credenetials works through the Web.

I tried to create a new account, but it shows an error like "Try again later".

It's a Jolla's problem or build bug?
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] David_#27:
To be honest, l don't really know, but l think that you can find your answer on the OP!
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] lal883:
The UI seems to be more responsive, UI transitions specifically, if I am playing a video in the device. I enabled frame rate display in developer tools and observed the behaviour in two cases. If I swiped down to display the shortcuts in events view or ambience shortcuts or just swiped between events view and home screen I could observe decent amount of frame drop. But if I have a video playing in Kodi (or any other video player) frame rate drops while executing UI transitions were almost zero.

To try to further investigate behaviour, I changed the GPU governer from msm-adreno-tz to performance. And the result was pretty good, UI reacted a lot smoother and observed almost zero frame drop. Did not spend much time playing with governors and observing the result. Will try to do so in coming days. To change governor, I echoed to /sys/class/devfreq/1c000*/governor

Honestly, i was trying to get aliendalvik run as well :confused: in which I failed. Will keep trying silently. There are some android apps which I hope to run on the device :laugh:
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] David_#27:

[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] LongLiveRem:
I have reinstalled Sailfish OS, so now it log-ins successfully. But there is a new problem: opening any 3rd-party app page in Jolla Store causes system reboot.

UPD: Not every app. Just random.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] PiggZ:
Great stuff, thanks for looking into this. if you find good combinations of cpu and gpu governors, I can look to making them defaults. I dont even know if all cores get used properly either, so thats another avenue.
