So 18 Watts goes in, then what is the current that charges the battery? Is it more than 1C? (Hint: yes it is: ~1.2 C)

https://xdaforums.com/showpost.php?p=75719144&postcount=986

I use 5V/2A dumb charger, for a phone that has only the fast charging implemented.

I've measured a "cowboy implementations" that pump 21 W (7V/3A) to the phone.

If I take 80% efficiency of the switched mode charger, then output is 16.8 W and @ 3.8 V (initial "discharge state") the current is 4.4 A => ~1.5 C

Thanks, but no thanks.

There should be a SW switch FAST(18W)/SLOW (9W), so the impatient people could ruin/kill their batteries faster

than those conservative folks who seem to know something about charging of batteries.

Developers (users in the text below) are free to implement a "better mousetrap" than the original LeEco charger design.

"The NCP4371 is designed to give a user a high degree of freedom to optimize maximum power and current limit

profile of the target application.

The user can scale both – maximum output power and maximum current limit

independently

[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] kurtn:
No in this context it's not Coulomb but capacity. Usually used for talking about discharge current. It is the ratio of current (in ampere) to capacity (in ampere * hour = Ah = 1000 mAh)

Hello@ThE_MarD

I flashed recently unofficially build but still facing low mic issue of headphones or seems like mic doesn't work with Jack adapter. With headphones, device mic's work but headphones doesn't. I'm using branded earphones and also checked with another. I can confirm it's neither my device problem nor my headphones. I saw your post and had seen some other's that it has fixed but I'm still facing. In aex mic works only for first call when adapter plugs before the call. After unpluging and plugging the same problem comes. Without wired headphones no problem with call in all Oreo roms.

Could you confirm that low headphone mic sensitivity problem with adapter has been fixed?

Do I need to follow any instructions except you have mentioned?

Thanks

Can anyone tell me how to enable themes via the substratum theme engine. It isn't working.....
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
Heyyo, hmm for Trebuchet that is out of my control as it is OS related issue and not the device. I'd recommend filing a bug report on http://jira.lineageos.org for that

For training Ok Google? I think for that it depends on which Gapps package is used. Can you please specify which one and what version/size?

So that's using the USB Type-C to 3.5mm with a headset it wasn't working for you? Did you try it with the Type-C adapter in both orientations? I believe there is still an orientation bug on LAOS 15.1 for x2 and it is something that is a known issue.

For that you will need Substratum with Adromeda. I'd recommend searching on Google for a guide as it could describe the process more accurately than I can.

Hello again,

I have tried what you advised. But it did not help. Same problem remains. I record a videı showing the problem and I uploaded it to youtube: This is the link of video:

https://www.youtube.com/watch?v=W6YOY53BGyE

There is one more thing I haven't tried:

I suspect that QCN part of firmware is corrupted. There is no problem with IMEI numbers, and connection to cellular network, but I have problems with wifi. Is it possible that wifi part of QCN is corrupted and if I get another X820's QCN file (IMEI numbers erased) and write my IMEI numbers with other X820's QCN file with IMEIRebuilder.exe program. If I write this QCN file, can this fix this wifi problem?

So I want to try this scenario. Someone can send me a blank X820 QCN file? I found another X820 QCN at XDA but it didn't work, because IMEIRebuilder.exe crashes when I open that blank X820 QCN. So blank QCN file should extracted with QFIL or QPST and IMEI should be erased by IMEIRebuilder.exe.

I will write my IMEI numbers to blank QCN and restore it to my X820. And I will see if the problem has solved or not.

Thanks

You use EUI and this is common and the same happens to lot of people including me.

Type *#*#46360000#*#* and disable everything. Then go to Tel. Manager and disable any data limit.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] coolman7:
I have tried a lot of ROMs including Lineage 15.1, DU 15.1, EUI 23S, 28S, Cuoco92's 23S, Cuoco92's 28S, Indian 19S. All of them has the same problem. I believe either there is a hardware failure at my X820 and I should return it to banggood, or either someone altered wifi section of QCN file before selling this phone to me (maybe this was a refurbished phone but banggood sold me as brand new. And previous owner might corrupted QCN file)

On the other hand, I already tested with disabled background resource control setting and Download Manager set to unlimited. And I get same result. But I've just tested it again with disabled background resource control setting. And result is the same again.

Did you already try qfil?. If I am not wrong there are 2 qfil files out there. One of them set all Partitions back to 14S factory state. If this doesn't eliminate your problem then propably is something faulty with the phone
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] coolman7:
I followed this guide and flashed Lemax2QFIL.zip file with FlashOne. And it converted to EUI 5.6 developer version, not 14S. And did not solve the problem:

https://xdaforums.com/le-max-2/how-to/guide-hard-brick-fix-qualcomm-hs-usb-t3492949

I can't find a QFIL file to convert it to 14S.

The only thing is remaining: Take another x820's QCN file, replace my IMEI addresses and write it to my X820. I already tried every other option.

Hey@ThE_MarD Yes I know that Jack adapter works only in one orientation in Oreo rom. Jack adapter works if letv logo faces down. I tried but worthless. Is mic of headphone working good for u? If yes please help me to get rid of this problem.

Thank you.

Heyyo, hmm if it's still not working for you then I'll double-check but last I checked it was working for me as I could tap on the microphone during a call and it would be loud if I tapped on the one on the 3.5mm headset and not the phone.

New unofficial build going up. Has some changes to doze, changed imx230 camera chromatix XML to X2 30s, defined two missing entries in audio platform info that showed up in logcat (I'll have to check later if it worked) and maybe removing libqseed3.so fixes the auto contrast bug... Or not. I dunno but please test. :good:

Hey [MENTION=6235294]ThE_MarD[/MENTION] happy Canada day and thanks again for your work. I want to let you know that if we connect Jack adapter just after reboot before the call, mic works good sometimes only for first call. I tested it aex, msm, crdroid and of course on los too but if we unplug and replug Jack adapter during call or for second call mic shows again it's low sensitivity problem. Again restart and plugging before call may help only for 5-10 sec.

I request you if you double check your build please just try to follow my procedure of checking mic.

Thank you.

Hi [MENTION=6235294]ThE_MarD[/MENTION] I recently flashed 02/07 unofficial build of Los and checked both camera and headphone. Camera department working good for me after flashing focus fix kernel. Rom flashed three times and found rom stucks in bootloop on second reboot. Third reboot is normal. First time flashing faced the app stoppage error during initialization of UI "Google pixel has stopped" with an option of close app. Next flashing, didn't face any issue like that. I'm not sure about the name of error but that was surely named like such that. Forgot to take screenshot sorry...

I found a different thing about headphone problem with Los. The mic works with headphone but phone's. Headphone's mic doesn't work. Try it yourself. After connecting the headphone with adapter block your phone's mic, you will hear nothing on another side of call. Use mic of your phone with headphone you will find that the mic which work is that of your phone.

I also tried latest version 01/07 of aex which includes your sound work and found that headphone's mic works for 3 sec during call for after each unplug and replug of Jack adapter. Mic sensitivity is improved little bit in aex but still low, noisy and not clear.

Thank you.

Use magisk manager app and install it. After installing reboot in twrp mode and flash magisk zip latest version and reboot. Just open the magisk app and check the root status. Congrats it's done.

For stop running back ground app use greenfy app from play store or from Xposed.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
Heyyo, focus fix kernel is not updated to reflect the changes so it might be unstable on this unofficial build. I will update focus fix kernel once these tests are conclusive that it is a good direction to go in.

For root? You have two good options. Magisk 16.4 (I'd recommend the 16.4 beta over 16.0 stable tbh) or AddonSU which is built specifically for LineageOS. Please Google search the two and see which is better suited to your needs.

To stop apps running in the background? Greenify. It works great, especially if you're rooted and grant it root permissions.

Thank you for reply. I run DFS tool and I attached screenshots. First screenshot is before pressing Read button, second one after pressing Band Preferred and Read buttons, third one after pressing RF BC Config and Read buttons.

As far as I can understand no WLAN band selected. But I can connect to WLAN, but wifi connection is not stable. When I install a new ROM, sometimes I can download several hundred MBs of data without problem, than problems start: Download interrupts, play store installation pauses and random reboots.

What should I do now with DFS tool? Should I select all WLAN bands and press Write button? I don't want to damage my phone by doing something wrong. Thank for help.

Before you try anything with the dfs tool did you try to download big amounts of data with other access points? This is the easiest way to determine if your download troubles comes from your AP or not

Hi,

I would like to try this build, but I don't know how to check my firmware version.

I'm currently using [ROM] [OFFICIAL] [22-03-2018] Resurrection Remix v6.0.0 [x2],

but the loudspeaker calls are not working.

Please, tell me how to check the firmware version, as the 20s is required.

Excuse me for my noob question, I searched the thread unsuccessfully.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] prajjwal.laad:
The loudspeaker calls work properly now with Lineage. You can't really tell by looking at the Baseband version (the only partial way to tell which firmware you're running) so I'd suggest you flashing an appropriate firmware for your model (latest one) from the first post. That's it and enjoy the ROM.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
Heyyo, it would be the last firmware you would have flashed or last EUI ROM. There isn't a specific way to check which firmware was last flashed though.

It's no issue to flash newer firmware onto your X2. Please check the first post and either flash one of the minimum firmware versions or one of the optional updated versions.

Yeah unfortunately Resurrection Remix Oreo official only had that one release and then the guy who "maintained" it instantly left for a different device. A Xiaomi Mi A1 is what I was told... That old and buggy build was taken down from Resurrection Remix's SourceForge account which is for the best as it will never receive an update...

Good morning all

So what i have seen on new unofficial.

It takes a little longer (havent timed it) to charge but the phone is cooler maybe [MENTION=6235294]ThE_MarD[/MENTION] can shed some light.

When charging and using the phone and temps starts rising the charging mode went from rapid to slow(havent got a qc3.0 battery doctor to measure current/amp). When it reached 41C it stopped and at 78% showed as fully charged. Had to unplug charger let it cool a bit and it quick charged to 100%

As for the camera im not seeing any differnce atleast to my problems. Im not a power user i take a pic here and there so my opinion doesnt have much of a weight .

In low light, same as before, Gcam video (arnova v8) is very dark-Slowmo is even darker and panorama is like it isnt using infinity focus so i get blurry backgrounds on landscapes which has a lot of depth - maybe its a gcam problem.

The autofocus is still working all the time in stock and open camera (no sounds or clicking never had that problem fortunately).

Nice addition that the unused sim icon is gone from status bar

Adaptive brightness is working ok, dunno if anything changed but i think the transitions are smoother, atleast to my eyes

Bug: On Settings - google - Apps connected if i tap and open an app like android device and then go back i get double listings of all the apps. I f i leave the menu and go back all is ok

Bug: Leeco stock charger still doesnt work at all as with previous unofficial

Request: Can we do anything about sms backup/restore on fresh install. On the backup menu i see sms text waiting to backup but never got them restored on fresh install. Ive read it only works on Pixel phones maybe thats why.

Also couldnt dirty install waited 10 mins on boot logo restarted again waited 10 mins but nothing. Wiped cache/dalvik but still nope

Im waiting for the rom to settle to see battery usage.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] astero666:

On this firmware, as with rr-o, the sound of notifications disappears.

If I'm not mistake, the stock sounds work.

Reboot helps but it's а long and you can also miss an important call / message.

[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
Heyyo, sorry about that. I updated the first post to reflect it. :good:

Heyyo and good morning to you too! There was changes to the thermal engine and performance as well so it might run cooler at times and hotter. It also hopefully fixes the ghost touches while using QuickCharge 3.0 (at least it does for me hehe).

QC3.0 failing to charge when battery is over 40°c is a known issue mentioned in the second post of this thread. It's one of those projects I will hopefully tackle someday soon. :silly:

Yeah for Gcam no matter what I try it always wants 1080p 60fps which doesn't work on our camera so videos can turn out dark.. I'd recommend ensuring you are set to 30fps to improve video quality or use Footej Camera or OpenCamera which can also improve audio quality by selecting different microphone inputs.

Good to hear! :)

For that I have no control as it is Gapps related. Can you please provide which Gapps you are trying? OpenGapps? MindTheGapps? Which version and size?

Stock charger is QC3.0 and falls under the known QC3.0 bugs

Hmm as long as you're using the official Android Messages from Google instead of the stock messenger app? It should sync your SMS (not MMS though) to your Google account and it can restore SMS. This was originally a Pixel only feature for Nougat but on Oreo it was enabled for all Android devices. My Google account shows it does sync my messages.

Dirty flash from Official to Unofficial requires migration tools from the first post otherwise it will fail on signature verification. It's just how LineageOS signs their official builds to prevent spoofing.

I'm sorry I've never experienced this bug. Are you using custom sounds or default LineageOS ones?
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] kurtn:
Have a nice Hey Yo!

Glad to see you are dealing with charging issues. I whant to use my X2 a longlong time. Maybe you can expand lifetime by being carefull with fast charging. Wenn do we need fast charging? When the battery is emty and we whant to use the phone for anoter hour or two. So we need fast charging only for the first 50% of Battery capacity. That doesn't hurt the battery at all, as long as the temperature is not too low. But can you please set the parameters for slower charging in the remaining SOC regime from 50 % to 100 %? This is a typical over-night charging, and it doesn't matter if its two hours or five.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
[youtube]AF2O4l1JprI[/youtube]

That video pretty much talks about it. Safest would be to cap battery at 80% but users would kill me if I attempted that :silly:

Quick charging is also ok since it is limited to 40°c (albeit we could go up to 45°c and still be within manufacturers specs as noted in GalaticStryder's kernel) but stopping charging altogether is a bug with our kernel's QC3.0 code.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] kurtn:
Are there more limits that can be applied to quick charging? Minimum temperature? Maximum voltage? Maximum current when out of limits?
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
What mainly needs to happen is attempt to revert the QC3.0 code we have and use the one GalaticStryder made for his kernel. His is built for both ZL1 and X2 as he owns both devices and adjusted and fixed QC3.0... I just need to have enough time to sit down and port that to our kernel, same with his USB audio as his works really good for the 3.5mm to usb type C and doesn't have the orientation bug

So tried footej and is better at low light but video quality is so so. Guess i have to live with that

Im using MindTheGapps-8.1.0-arm64-20180610

Downloaded android messages as i was using stock app and i will try it out

I dirty flashed on top of 07/01 unofficial (yeap i wished i waited 1 day because i had to clean install also from 06/26 to 07/01 and again to 07/02). Dunno if i had to do a third reboot as i read few posts back or maybe i should of unistalled magisk first

Also a spoke too soon as adaptive brightness is acting up on me. In a half lit room (tonight) going back and forth from chrome to settings, brightness was shifting from (sometimes very) dark to bright for no apparent reason. In the morning with alot of sunshine brightness is shifting as it should. I will keep an eye on this.

Last i cant add my gmail account to stock email app. It says wrong username or password. Hotmail is working fine

Thanks for the hard work
