Doubts about how to install the system

Hello,

I am very thankfull of the work you are doing with CM 14.1 for LeTV X900.

My question is: I have installed in my LeTV X900 (chinese version) the system SO LightFW.ExTra.16s-6.0.1-Ver.1.301.MaX900.By by SPZJulien; and when I tried to install this system, via TWRP 3.0, I also installed along Root.Xposed.systemLess.TWRP.installer, to have root access via TWRP.

My question is how can I install this CM 14.1 for LeTV X900 and keep access to root via TWRP?

If I install this version CM 14.1 for LeTV X900 and after that I want to go back and install SPZJulien version, is it possible?

Thank you for the attention.

Best regards.
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] Carlosmff:
I asked same before... Yes, you can go back to Stock or Custom SPZJulien.

About Root I think you can still install SU throught TWRP.
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] ABM30:
This last ROM for X900 will root during install with SuperSU-v2.79-SR2. So it will be rooted after booting up (it restart short after first boot to finish rooting but then will finish and start after 3-4 min)

Xposed is not stable for Android 7.1.1 yet so I not recommend to try it (nor install one for Android 6!!!!!)
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] Carlosmff:
Hello. I've installed this ROM.

Very awesome.

First boot with errors due to SIM cards. Need to reboot, everything ok after.

Setup went well ans smooth.

Camera does not work. Tryed other apps, no good...

Messaging app does not work. Changed to GO SMS Pro, did the trick and works now.

Don't know if Fingerprint works because I cannot find option...

Can' activate NFC. Allways disabled.

Other stuff works great...

Really good job. Congratulations.

Ps: FlashLight doedn't work eather.

Question about 4G band in LeTV X900

Hello,

Thankfull for your work on this device X900.

Can you tell me if band 20 for 4G LTE at 800mHz is available for LeTV X900, in this system CM 14.1?

Thank you for the attention.

Best regards.
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] ABM30:
I don't own the device and I haven't modify the firmware, so you will have the default radio/phone freqvencies.

BTW, below a link for a NEW VERSION

FOR X900 ONLY (TRY IT ON YOUR OWN RISK)

I modified a bit the boot.img to , trying to make it compatible with nfc and fingerprint sensor. Added some files/settings for camera. let see if something has improved.

[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] Carlosmff:
Hello. Could this be installed over the current version CM 14.1 or it need to be installed as new? Because I really don't want to configure all over again...
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] ABM30:
The ROM is for testing purposes, I can not test it because I don't have the phone.

Better to install with wipe cache, data, system Dalvik/ART before install the ROM and after wipe cache and Dalvik/ART.
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] borg79:
I don't think band 20 will work as I have already tried the "unlock LTE" method, even I can add all the LTE band options to the rom, it won't receive the LTE signals of those bands .

Hi, really excited to see the progress for our x900 with CM 14.1. just one query --- do I need to update recovery also. Currently using TWRP 3.0
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] mandarthedon19@gmail.com:
Hi, finally I successfully installed this ROM on x900. Booted well. Fingerprint, camera and flashlight not working.

Nice to see google apks, SU preinstalled. Call quality also good. Will test other functions and let you know.

Great work indeed.
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] Carlosmff:
Hello all. Installed this version and Camera still not working, Fingerprint not showing, NFC is ON on settings but I think is not working, flashlight not working and when you edit settings from Tile, phone crashes...

Other settings and apps working.
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] mandarthedon19@gmail.com:
Just update. My lemax x900 suddenly was off with blue led on. May I know what's wrong here?? I rebooted device by pressing power+ vol up twice.

I also noticed message app is also very slow. Can receive and send SMS but app takes time to respond back.
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] ABM30:
below a link for a version from 23ian2017

FOR X900 ONLY (TRY IT ON YOUR OWN RISK)

Added some files/settings for camera, DOLBY AUDIO, radio FM.

Give a try and tell me how is working.

https://mega.nz/#!c0tWjZSY!jzBk_NVOzGLJA6zNmQ5SYRd58AOvNFoJOywQeYc3_PA

[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] Credomo:
Hello,

I would like to make a clear point on LeEco Le1 Pro (X800) CN version.

I've installed your last update : 2017ian18.

Working / Corrected :

Everything works fine (bluetooth, GPS, mobile data, WiFi, battery consumption, Security, …)

Camera : Open camera and official camera app works fine.

WiFi <-> Mobile data : Works fine now!

Not working :

IR Blaster. Tested on some apps (IR Remote, Anymote Smart Remote). The hardware is not recognized.

Tethering : Error fired once activated. How to log this error ? That's the biggest problem I've found.

Flip cover case open/close don't power on/off the screen.
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] ABM30:
Thank you very much. I now about this problems, I am looking for solutions. In next build I will include the Dolby audio which I put in X900 test version.
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] mandarthedon19@gmail.com:
Installed this new ROM. Booted well. Camera apps and FM not working. FM says not available. Dolby works like a charm. Finger print option is not visible.
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] Carlosmff:
X900+ has no FM radio support...

Same problems remaining... Camera, FingerPrint.
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] borg79:
I try the rom, camera still not working, but by checking on the log, looks like there are some improvement, the IMX230 sensor is found but still, there is some other sensor missing, may be the front camera, not sure. The log is attached for your reference.
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] ABM30:
Yes, that is true, in fact X900 has no radio, I remember wrong, so I will take it out.

Back to work, trying to find solution for camera and rest.

BYW, camera give some errors or is just black or other color?
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] Carlosmff:
Just black screen. No matter what camera app Install, always black screen and then, maybe 20 sec after, Camera has stopping...
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] ABM30:
Try this addon libs (i added some libs missing found in logcat) and tell me what changed: :confused:https://mega.nz/#!h5k0RZRC!8xrDIsduTf3R6H1jIJhKpddsJjWb4z3l5nK5JWQtBVg

P.S. on X800 this addon will crash the camera! but maybe it works on X900
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] Carlosmff:
With this lib I get:

"Failed to open Camera.

Camera may be in use by another aplication?'

I'm trying with Open Camera.

With default camera, it just crashes...

I can play with settings...
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] borg79:
I just try the patch, only opencamera works a bit (at least showing a setting screen !), the googlecamera still not working. As I look into the dmesg log this time, I find that this error

init: cannot find '/system/bin/cameraserver' (No such file or directory), disabling 'cameraserver'

As I search through the rom, there is no "/system/bin/cameraserver" exists, may be this is why the cameraserver service cannot be initialize when the phone start up.

I think the reason why only opencamera works a bit is because it supports Camera2 API where googlecamera only works with previous version of Camera1 API !

You may find this information http://ruanhongfu.me/?p=189 useful.

Log is attached for reference.
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] ABM30:
OK, I put files together, including cameraserver.so in bin folder and lib files in vendor. Let see what happens.

On X800 it won't recognize the camera, because this time is for X900 good, i hope.:fingers-crossed:

https://mega.nz/#!g4dlzZrD!Tpy0ciRwYSzA6UbGulXSe3PUGKXC-sMZ8hOupsB0d7I

P>S> What is interesting is that X800 don't need camera server to be present!
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] Carlosmff:
Same error on OpenCamera.

[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] Carlosmff:
Yeh... I love this ROM so much I turned it into my daily ROM... and I need take too many pictures in my work... "Well, it's just a malfunction in camera boss... They are trying to fix it... In the mean time, I need to take the company camera... Sorry..."

[MENTION=1728245]ABM30[/MENTION] From what i have read about max, we have the same camera that the xperia z3? Wouldn't it be possible to take the libs from any xperia z3 aosp/cm/lineage os 14.1/7.x rom?

Like this one: https://xdaforums.com/z3/development/rom-pixn-rom-t3531628
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] ABM30:
I am very pleased that you liked, that is meaning my work has sense. :good:

Well, in fact they are taken from Sony Xperia Z3+ LineageOS, but there are a lot of thing bounded together, I am looking forword to find a solution.

It will slow down a bit the work because I return to work tomorrow (I was in holiday! ;) ) but keep working on ROMs. We are closer any way.

Maybe Borg79 will make another logcat on last ROM to help me identify the rest of problems, some ideas I have, but....keep eyes open!
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] Carlosmff:
Could it be extracted from an uninstalled ROM? Cause there are many CM 14.1 ROMs for Z3... Just tell me how to do it and I get it for you...

Otherwise, maybe asking for someone in the Xperia X3 forum?
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] ABM30:
I got files, not that is the problem. I can extract them from any ROM. The Sony Z3+ seems to be the most closest to Max 1 because it has the same CPU (SD 810) and camera (Sony IMX230 Exmor RS) But the things are a bit more complicated.
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] mandarthedon19@gmail.com:
Great man , hats off to you. Without having actual device you are able to build this ROM for x900. This is commendable. Great work. I am confident you can resolve the issues.
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] 266APP:
There is a very serious BUG! Very serious！ Very serious！ Very verification! Now I can't listen to music, a music sound will be other sound coverage, such as the lock held. You have to press the volume button to continue playing the music. It's really annoying, as long as I click on the touch screen, the music will be covered by the sound. I am very disappointed. Worse and worse.
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] borg79:
I download the AOSP 7.1.1 R13 source code and select the angler device ( to make sure the build to be successfully because it is the official device tree). After compiling the source code, I discover the file "/system/bin/cameraserver" in the "OUT" folder. I just wonder does "cameraserver.so" equivlent to "/system/bin/cameraserver" ?
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] borg79:
As I check the sony device tree from here https://github.com/SonyAosp , I found some changes for camera in some device tree for Android 7.1 . When I compare the structure of the device tree with those from here https://github.com/sonyxperiadev/device-sony-lt26. I just doubt the reason why camera in X900 is not working is due to the fact that we are using the device tree from previous version . If this is the case, then adding library files ( extracted from other Sony rom ) might not work ?
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] Carlosmff:
Hello ABM30...

This guys are having the same problem with Camera for Le Max 2 and found some Vendors and Device Tree...

Don't know if it helps, but anyway... here

testing soon, gonna try to dirty flash this ^^ other wize ill just try to restore data ^^

[EDIT]

Might have found a charging bug for the 2017-01-23 build version on x900+, when fully discharged not charging/charging very slowly it's been charging for about 15 minutes and still got 0% battery left.

Tried to boot it up, and there is only a red light flashing all the time when plugged in (might have bricked it? not sure, continues...) **Crossing fingers**

[/EDIT]
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] Carlosmff:
No good... Here's some errors...

Tryed with Open Camera, Stock Camera, Camera MX.

Restarted as demanded, changed default location of photos... Still same.
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] ABM30:
Try this: Delete your DCIM and Pictures folders (make backup first!). Start camera and let create fresh DCIM and Pictures folder by phone itself and see if something has changed.
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] ABM30:
NEVER let phone to discharge totally, to 0%!!!!! LI-Ion batteries don't liked!. It happens then after discharged totally you need more time to charge and it will lit up maybe just after reached more then 10% !!!!!!!! better charge it most frequently then let it dry out...so to speak!

Once i needed 30min till the red led appeared and more till the phone had start again, I thought it was dead to! (it was not the LeEco but the situation is the same!)

SO BE AWARE!!
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] Carlosmff:

Restated phone.

Opened Camera, same errors.

Folders have been rebuilted.

Thank you for the heads up, got 3% now and gonna let the device charge over night, the device did not get bricked nor broken in any way, it does takes a lot of time to get +% tho, never gonna let that happen again ^^ the update as of today did not solve the camera problem (made a backup to be safe, dirty flashed the update and tried a fresh install but same result as before) had only 1% left after the backup but flashed the update anyway ^^. BTW, saw that the flash script were still showing the date 2017-01-23 during the install ^^ Cheers

I'll give it a try later...

Just let me ask you something... If not working, are the Stock ROM binary files, after installed, usefull? I mean all the ".so" files.

Cause if it does, I'll install stock ROM and extract all binary files from Camera, FingerPrint, NFC, FlashLight, what ever you need...

Don't know if my question makes sense...
[LeEco Le1 Pro ROMs, Kernels, Recoveries, & Other D] ABM30:
Thank you but I have all kind of rom, STOCK AND CUSTOM, OLDEST AND LATEST (20S). THE PROBLEM IS HOW TO COMBINE THEM TO WORK RIGHT.

But thank you very much any way. Because I need to work on "blind"so to speak is much harder and take much more time.

I don't want to make to many changes at a time, because then i can not determine where is the cause of problems.

But I hope in final I wil fix the camera problem.

Some curiosity...

I've installed stock ROM and added a few cameras.

Also installed Camera Blocker Free to lock my camera from being activated without my permission.

So, I started one of my camera app and came the errors...

"Camera has been disabled for security reasons...

Can't open camera app. Maybe is in use by another app.

Camera error, maybe a reboot is needed...

Camera error, missing drivers?...

FlashLight can't be opened. Icon greyed out"

Bla bla bla...

This took me to those errors I reported before...

I know this has nothing to do with errors we are getting from this 14.1 ROM... Or does it???

Some permission issue? Some app blocking camera apps? Dont know.

Here's what we need to try...

1. Uninstall all camera in 14.1.

2. Reboot to Recovery.

3. Clean Dalvik/Cache.

4. Reboot System.

5. Install Open Camera.

6. See what happens...

Anyone with 14.1 installed could do this and tell if something changed?

Hello,

If I have installed CM 14.1 in my X900, how can I do to make reboot to recover?

You were proposing to clear all the camera app's, do reboot to recovery, Clean Dalvik/Cache, and do reboot system?

And after that install a camera app?

Thank you for the attention.
