I'm trying to unlock 2 of my kaisers and it seems as though whenever I try to change the radios my screen goes black right after it reboots and won't let me do anything. Maybe I'm just being brain dead and forgetting to do something, but I unlocked my other Kaiser 2 days ago and I'm 99% sure I'm doing the same thing I've beendoing.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] JoVa619:
Anyone have any idea?
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] NotATreoFan:
If this is related to SIM unlocking your phone, please check that thread first. Your question is most likely already answered there.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] JoVa619:
I checked, I didn't see anything describing this problem. I've treid with both different methods, JWC2001's and the stickied. Tried on vista and XP. Neither worked.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] _Alex_:
You still should be posting there, because even if this thread isn't redundant and you find an answer in this thread, some other person will come along and have a very hard time finding this thread amongst all the other threads that are/were redundant. :)

There are HUNDREDS of threads that mention radio issues and the relevancy of the thread title not matching the contents of sim unlocking issues will definitely make it hard to find.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] JoVa619:
I tried posting there when I didn't find an answer I had figured might as well make a post on the main boards, my apologies either way. Just frustrated that 2 poeple can't use there cell phones ATM because I'm an idiot.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] C Brown:
Just flash any 6.1 rom it will fix it. once your done with that just run step 2 and 3 and you'll be set.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] TimSykes:
this happened to me too. Try putting on your original radio, that will fix it. Or upgrade to a 6.1 ROM, and put on a 6.1 radio. Its just radio that will not work with your ROM, they all don't work with each other.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] C Brown:
Yeah just make sure you follow the directions closely it will save you alot of headache.

Hey! This kernel works only on EUI right?
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] GalaticStryder:
Yes, this is for EUI at the moment.

XDA has had a little problem I guess or I have pressed the button to apply my XDA DevB project while it was spinning for more than a minute, wow! If any moderator can delete the other threads I appreciate, sorry for the inconvenience.

EDIT: 502 Bad Gateway but it posted, somehow.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
Heyyo, congrats on the kernel project GalaticStryder! :)

Yeah it's weird... it's definitely an XDA Forum bug. Happens even on edits. I've made the same mistake by accident too a month or two ago so they haven't fixed it yet I guess...
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] GalaticStryder:
Thanks, I'd like to update the thread on what the new version of today has but I'll wait a bit, it's just a classic (CAF) Kernel for EUI with patched battery phandle and faster charging compared to stock but still safe, same constants just a little faster due to updates and fixes I made in charger code.

Hope I can update this and the Pro3 thread as soon as possible with the new stuff.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] kewlest22:
[MENTION=6175749]GalaticStryder[/MENTION] highly appreciated that you chose to work on this device, really looking forward for this kernel to expand its compatibility to all roms, God speed!!

Working on eui 5.8 16s? Please tell me
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] GalaticStryder:
Backup your boot partition and flash it over, I've only tested it on 26S but on Pro3 my Kernel ran on all versions I tested. Make sure you're not encrypted otherwise it won't flash (Indian 16S for example), to get rid of encryption you'd flash the latest Chinese version or one that is based on it.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] Mahz4130:
My leeco set has this strange color calibration issue-its very warm and yellowish- due to which I don't use stock roms. I also am able to use only those custom ROMs which have color calibration or kcal built in. Is it possible to implement kcal support in your kernel? Thanks a lot.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] RubeusHagrid:
Wow! It's awesome... Great kernel...
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] Mahz4130:
Can you check if there is an option in kernel auditor titled as screen which has color calibration?
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] giaur:
Same for me. But most people keep saying I am wrong. Not kcal, default color calibration in kernel should be changed, because it's invalid.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] GalaticStryder:
Could you dump what type of panel you have got and variant? Mine seems to be fine (truly) but I see the panel calibration has a few faults on the others from stock itself, and both open sourced codes for Max2 and Pro3 are the same regarding the panel, no updates.

Need to boot the stock Kernel again and dump all I can from Kernel logs or... reverse engineering.

If it is not excuse to ask, will be there any updates for Lambda Kernel for LG G2 ever?
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] giaur:
Truly I guess. Screenshot:

I'm on Lineage 15.1 currently. To get it white I need to set LiveDisplay 9700K. Default color calibration looks terribly wrong.

Btw is your kernel suitable for Lineage 15.1? Or it''s for EUI only.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] Genie's:
BTW, works perfectly on Le Max 2 Small eUI V18.

My screen seems yellowish cuz I turned on Reader Mode.

If turned off, my screen is white enough
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] N-Gage4ever:
Hey thank you so much for your kernel. I can't use EUI ROMs because when quick charge is on it never charges more than 1000mH.. But on custom ROMs I can charge my phone even with 4000mH. It's a life saver sometimes.. Does your kernel provide this feature for the EUI [MENTION=6175749]GalaticStryder[/MENTION]?
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] RISS23:
What is the battery life with this kernel?
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] GalaticStryder:
Watch out, the default charging rate for QC2.0 is way lower than 4000mAh (that's the max of QC3.0 on Pro3 which is HVDCP3), I think a good rate for the Max2 is around 1500-2000mAh (HVDCP) but that can be adjusted in future Kernel changes, for now, the OEM value from 26S seems to be at 1500mAh out-of-the-box, the open source Kernel I didn't test on Max2 but should be less than 1000mAh without patches.

They seem to have lowered the values recently but I don't see any reason, the 4,1V input voltage should not create too much heat compared to the 3,8V they are setting on stock Kernel.

It chargers 'ok' as it's right now, I didn't need to charge it more than 2 times yet with the new changes so... need to see, yet.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] N-Gage4ever:
Thank you for your answer. Our device supports QC3,0 and as I said I could able to charge 4kmH on [MENTION=6416309]moto999999[/MENTION]'s slim ROM.. Please focus to improve charge speed on your kernel so that it'd be more useful
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] TheMichalos:
Like people said before charging could be a bit faster. Else than that only my other problem is some noise on low volume on speakers.

what is the sec patch level of this kernel?
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] oneNight1:
I guess you are reffering to that topic about the qdcm xml files? Kcal can certainly help, but creating proper qdcm files would give much greater control and better results and allow actual colour calibration.

The files contain a lookup table for the screen and also lots of other calibration profiles.

I don't know how kcal works exactly - maybe it edits these files?

My panel is the Truly panel and i have massive screen issues, black crush being the main one.

It may be that yours has issues too but you haven't noticed?

What variant is your phone btw? Mine is x829 silver, 64GB.

Have a look at this topic i made and tell me how far you can see down to at different brightness levels:

https://xdaforums.com/le-max-2/how-to/le-max-2-black-crush-survey-t3744594

Adding KCal to this kernel would definitely help as having some way of tweaking the screen is better than no way.

Reading this might help too:

https://xdaforums.com/le-max-2/how-to/unbricked-devices-split-screen-fix-t3752768

I am guessing here, but i think maybe le eco didn't have official access to the qualcomm colour calibrator and so just edited a sharp qdcm file for their own ends.

I'm not sure how it is in other roms but on EUI based ones (at least, i tested with small EUI), if you edit the qdcm xml files to "fix" them and be like other phones with wrapping <Calib_Data> tags then it breaks the functionality of the EUI "Colour Mode" functionality (settings, display, colour mode).

It seems that in EUI at least, the empty <Calib_Data /> tag is what's required.

If you have any more questions just ask.

The tldr of it is that KCal would help a lot for people stuck on EUI and that understanding the qdcm calibration would be the ideal because that would give a huge amount of control for properly calibrating the screen in a way similar to computer monitors etc.

Understanding qdcm xml files is something that would benefit a lot (all?) of qualcomm based phones.

If you or anyone could reply to my black crush survey with your own results, that would be greatly appreciated.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] GalaticStryder:
Kcal is a low-level (Kernel) fine-tuning driver that uses the MDSS (panel communication framework) to adjust the panel, it just exposes what the panel already does "inside" the scope of Kernel to a userspace module (that you control with root or within the ROM itself with SELinux policies) whereas the QDCM is a calibration for the HW composer within Android's UI (SurfaceFlinger) that you can tune for that panel but it doesn't "write to the panel" like Kcal would via Kernel.

Regarding EUI I don't really know because I'm not using it anymore but their Color Mode implementation isn't on Kernel at all, an implementation in Kernel usually doesn't stick after a reboot too so we always write (used to do with Synapse) to a file that would after boot be read and reapply the calibration via Kcal.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] giaur:
[MENTION=6175749]GalaticStryder[/MENTION] - good to see you are not using EUI anymore, nobody (almost) likes EIUI, because it's actaully a crap. Do you have some idea for color calibration (I mean, how to correct it)? I have even compared with other phones I own (LG G5, OnePlus One) and, with Lineage and Live Display. If I set the same color temperature on all of above devices, G5 and OnePlus displays shows very similar colors, but LeEco is much warmer, whcich is obviously wrong.

Most people don't even care, but I do care and I'm not kcal and kernel adiutor fan actually. Better to solve provblem, instead of hiding it by kcal and some additional apps auto starting (like kernel adiutor), more - kcal needs root and what if I don't want to be rooted.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] GalaticStryder:
There's a simple driver I wrote to correct that via MDSS - again, that's the way to do it - but doing minimal work via DT, it's hardcoded to adjust the panel defaults, the only problem is that it's conflicting with other solutions but I'll get that right on my LOS 15.1 and share it when I judge it's ready, I'll probably ditch LiveDisplay in favor of using the native one that came with nougat to just protect your eyes and let my own ClrMgr take place with a few modifications we can make it adjustable from userspace.

We need to see, I have other priorities now regarding the Kernel which is I've rebased on top of the latest one from CAF based on the work I did on AOSPA and it's rocking very stable so far... maybe the people in the team take it as base before the nightlies start to roll out which would be awesome or I'll need to keep adapting some of my changes to it and have a very ton of them to push which would be pain to do.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] XDVRMX:
Working great!

Good performance and battery here on GizROM based on LEUI 28s.

Maybe when you're free you can think about adding maybe some governors or some I/O patches.

For now it's a good reliable kernel for daily use.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] fusticky:
Maybe the kernel is not meant to be flashed over Eui 6? I tried flashing it in TWRP after backing up the Eui 6 port from x850 by prsapphire. It flashes without problem, telling me it passed. But when rebooting, the phone immediately returns to Recovery. I can only restore my backup to boot up and use my phone again. Was hoping to try out this new kernel.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] GalaticStryder:
You can't boot LA.HB (M) Kernel on LA.UM base (N) due to the ROM APIs not matching the Kernel ones, which is a HUGE difference in this jump from M -> N, but not that much between N -> O.

There's already work going from someone else to "port" my LA.UM Kernel to EUI6 which would be damn easy, just enable modules and a few changes to defconfig of either my LOS15.1 Kernel branch or the old AOSPA for Pro3 which I'm not updating since the new one for Oreo works just fine on N.

I'm not having much time this week but surely we'll have some news in that regard sooner or later. Just stay tuned on hope for good, we're gonna beat OEM software together!

[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
Heyyo, are you referring to Android Security Patch Level in about phone? That's tied to the ROM and NOT the kernel.

The only way Android Security Patch Level in EUI ROM will increase is if LeEco release an update with newer Android Security Patch Level with it.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] GalaticStryder:
The king is dead, long live the king! Introducing Azimuth, a new Lambda Kernel.

I don't wanna extend for much longer to start rolling out the dices for Lambda Kernel on Max2 for real, it has been a very long time since I started working on a different way of thinking the Linux Kernel on modern day's demands of simple & secure mobile OS experience and the Kernel is the base and core of it.

Today we're introducing our shiny new Lambda Kernel for anyone running custom ROM, if you're not, switch right now and get Lambda going...

This version, Azimuth, is a pure HMP build, bleeding-edge as Google's reference 3.18 Kernel is merged-in, latest CAF tag is merged-in, AOSPA optimizations are in, some CopperheadOS security patches too (most of them hit performance too much and do not worth it, slab hardening for example). Clang 7 is the default compiler, and is less than 15MB!

Before you flash, make a backup of your boot.img just in case.

Warning: NOT compatible with Treble at the moment, next DEVEL release will roll out with a custom Treble detection patch (since Treble uses CONFIG_MODULES=y) that may force us to split between Treble and non-Treble builds. For now, we're going without it, let's wait for stability and other feedbacks on it. [MENTION=6235294]ThE_MarD[/MENTION] says it's good but I didn't have time to upgrade my Pro builds with Treble support, yet.

Seriously, it's a HUGE and completely different Kernel, I could go on the changes I made on top of CAF for days... I'll update the O.P. as I check the history precisely.

Check the history if you wanna have an idea if what's inside, you'll need to go all the way back to March :)

The Downloads are on Github releases page for easier issue tracking, if needed.

I haven't used the phone as a daily driver to put it through a complete battery cycle. I've just tested stuff like facebook/messenger/instagram(full/lite versions), viber, wifi/bt/data/calls/hotspot/location, overall smoothness and such - basically seeing if everything works and it does.

for the past week I had the phone in deep sleep(no wake ups at all) with no internet/sim - easily lasted 7 days on battery.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] azzammalik:
Thanks Dev. It seems like my random reboot issue which is common problem in x829 is solved.

Still its too early to call but I will report after two or three days of usage.

How to remove all kernel related files before flashing new kernel? I have tried some zip via twrp on g3 which remove all kernel related files.

Is there any script for this device?

This random reboot issue and all app force closes after some restart is really frustrating.

Dolby work on Carbon also...

I have the some what similar experience with carbon rom, amongst Oreo this is the best. But there is a difference b/w Dolby on 7.1 and Dolby on 8.1. Once you listen the music in cdla earphone, you won't want to go anywhere except 7.1, whether its RR or PA etc.
