The same problem was occuring in several roms, even on Flyme OS. I have flashed again the LePro3 switch rom and flashed Miui 9 V10 by venezolano69. Everything works fine so far, and NFC is working too. The rom is good (maybe not as smooth as AICP but at least I have internet and NFC working!).

so Dany which version do you suggest for cool changer s1 4/64?i heard the JUI 7.1.1 is not so stable
[General Topics] Danny_Dewet:
Hi, right now I'm using the LineageOS 15.1 with Black Screen kernel goes really well, the best is the AICP but the last build is not stable
[General Topics] Danny_Dewet:
LeEco Remote App for ROMs like: Lineage OS, Mokee, Resurrection Remiz etc with Kernel BlackScreen. (Infrared)

Link: https://drive.google.com/file/d/11yux9-yAGk3LGPHUMuGUxi7XOrbWeEr9/view?usp=drivesdk

Installation:

1 - First install BlackScreen Kernel from recovery and reboot

2 - Flash Remote App zip reboot

Enjoy!

already tried this..anywayz i found another unofficial release from december that works.i navigated a bit in 8.1 seems stable no major issues or crashes exept that i cant install external .apk files.i download the file and when i press on it says:cannot open file.we have to find a solution for lineage os and model number error code 7.maybe an email to the developer so he skip the model verification.btw antutu score on 8.1 with 2.15 kernel 144.000,waiting for 2.35 kernel 8.1
[General Topics] Danny_Dewet:
If you have 4/64 variant, I think you have the base frequency of 2.35 without installing any custom kernels.

Bacause if I remember correctly the frequencies are these:

C105 (4/64): 2.35GHz

C105-6 (6/64): 1.9 GHz

C105-8 (6/64 + NFC): 1.9GHz
[General Topics] georgts:
i have the 8" one
[General Topics] Danny_Dewet:
With NFC? You can use this if you want to return on EUI: https://www.needrom.com/download/c105-8-stock-with-nfc/

Anyway i have obtained with the AICP 8.1 175000 points on Antutu, and I honestly do not understand this move by LeEco in lowering the frequencies.
[General Topics] Danny_Dewet:
The 2.35 GHz kernel for C105-6 and C105-8 it is not easy to obtain a stable result, because the frequency is blocked via hardware, not via software.
[General Topics] Danny_Dewet:
I do not think this is the problem, in a Chinese forum there is 2.35 Kernel for ROM EUI and has no problems and is also stable.
[General Topics] georgts:
when the device appear everyone was saying "cool-hot" changer..the only device who is using the 821 @ 2.35 is 3T, htc aslo downgrade to 2.15 cuz of heating problems.There is no other explanaition buy a 821 and use it on 1.9

[General Topics] georgts:
the first version you posted...the 3201 doesnt start on my phone and on the 3210 i cant see the phone as an mtp device in my pc.after 5-6 tries i finally installed the conversion rom and the new 8.1.. maybe the usb post of my pc didnt work as it should.btw every time i want to install a new version i have to run the s1 to pro3 conversion rom?
[General Topics] Danny_Dewet:
Strange, idk. Maybe the C105-8 is not fully compatible.
[General Topics] georgts:
yeah, thats a possibility..anayway after installing the new 8.1 put the phone in the fridge for about 20 mins,i ran antutu 175+++...
[General Topics] Danny_Dewet:
LOL why in the fridge XD

C105-6 has no overheating problem even at 2.35GHz
[General Topics] georgts:
as the antutu stresses the phone heat raises.when heat raises you have drops on cpu frequencies.try this in room temp and fridge temp you will see the difference

So this tuto(XDA) is not for C105-6?

PD : While I wait ..do you know how can I fix double notification in JUI?

I do not think, you can try but I do not recommend it, because the bootloader could block the installation.

Hi, thanks Danny it worked. Antutu from 150k to 170k+.

Everything was great until step 3-6... There is no such thing like "Advanced > Config Device> Set_Device_zl1" in twrp. So i downloaded twrp from this post:

It bricked my phone! No recovery, no os, no adb, only fastboot (flashing old version of twrp from first ZIP package worked). After ressurection i flashed from fastboot the newest version od twrp (still no config device>set device option) and flashed my custom rom without a problem.

My device is c105-8 4/64 nfc, aicp 13, 2.15 kernel.

I think my device is heating less now lol (stock was 1.9).

Anyone using 2.35 kernel ? How its going?
[General Topics] Danny_Dewet:
The 2.35GHz kernel does not exist on Android 8.1, only on JUI and on ROMs based on Android 7.1, because it is unstable. For recovery as I wrote in the first post, the preconditioning was tested on the variant C105-6 (6/64) so ​​it may be that on other variant it can give problems.
[General Topics] stefano.parizzi1:
i just recived this phone and i want to try this procedure and try some roms but before i do , i want to be sure to be able to go back full stock from cool s1 JUI to Leeco pro 3 and then back to having a stock cool s1 on JUI which is actually a good rom for me

is it possible to revert the procedure? and if so, how?

For anyone who has converted the device and has a ROM with Android 8.1, do not flash the 2.15GHz kernel with the latest builds of the ROM based on LineageOS, it will decrypt all your data, as soon as the developer releases a new version I will do a specific post.

Can i fix it somehow

There is also a conversion rom to S1.

[General Topics] stefano.parizzi1:
is there a link to this reverse conversion rom?
[General Topics] starryin:
I flashed the 416 lineageOS, now I cannot mount /data in twrp (I remove the screen lock password). Does it mean that i cannot flash another rom unless twrp is upgrade? I cannot find Cool S1 twrp update on its official site.

Here it is.

I think that's because it was encrypted. You'll have to format data or use another twrp.

Well, I got big problem. I have flashed the conversion rom to go back from LePro3 to S1 system, but once rebooting in recovery, the phone cannot access it. It just try to load LeEco recovery then shut down immediately. In fastboot mode I have a menu which propose me to start the phone, restart bootloader, go to recovery mode or shut down the phone. But my phone is not recognized by my computer (it was before). So I cannot do anything. Anyone had the same problem?

Edit: well, I have just went through minimal adb installer and could open the command window, and flash twrp via fastboot. Everything is fine, I could went back to original Eui (well, not exactly original, but a Chinese version without Live services). As my wife just wanted her phone to work I think it is the best solution so far.

When you do the conversion, in theory you already have the TWRP recovery installed. The phone turns off immediately because the system does not start, so when you turn it off you have to hold down very quickly, power button and volume button up.

Hello

Very nice tutorial, but I have problem.

I have installed aosp Extended 5.4 Android Oreo 8.1 with 2.15GHZ April 9th build like you, and everything works fine except the device does not charge at all. it shows that it is charging (very low current) but battery just drops. Doesn't charge at all when turned on, off, or recovery. I had to flash grossoshop rom to be able to charge.

I have also tried newest aosp Extended, if you use twrp zl1 3.2.1-1 no problems with encrypted data. But did not fix the charging.

Do you have any idea what could be the cause of this problem?

edit: I have this problem on all android 8 roms I could find. Charges fine on paranoid android and stock rom.

You can install any roms, I have the same model (the one with NFC, not sure NFC will work though...it was working for me in Miui9).

[General Topics] Qidamin:
I have flashed back to a light original EUI version (without the Live services) but it seems that the second sim card doesn't work well. My wife is using China Mobile as main card and China Unicom as second card (only in 2G) but the signal for the latter is pretty bad. She cannot get 2G most of the time. Also the NFC is not working properly. I still have the TWRP that is mentioned in the first page. Should I go back to original recovery (and how?), should I update the TWRP? I don't know if it could solve the issues (NFC is not a big deal but the 2G signal is).
