So I bought this for my wife, and just got it yesterday. I rooted and flashed Small EUI on it. But the battery life is pretty disappointing and the fingerprint scanner hardly ever works.
Are there some fixes for these issues I'm missing out, or a new stable ROM you can suggest me?
Pretty gutted as it looks like a great phone.
Cheers
Heyyo @Mae7 if that ROM isn't functioning good for you I'd recommend flashing a newer version of the modem firmware. I know it sounds odd but it definitely affects the fingerprint performance when the device is asleep.
Chinese 26s 05.09 is the one I recommend as it is the last stable one that LeEco released.
https://yadi.sk/d/woKdrlRrv8yhr/Китай
Developer 466D is another modem firmware option that some users prefer
https://yadi.sk/d/woKdrlRrv8yhr/Для разработчиков
Otherwise? If you're interested in sticking with EUI ROM I've heard that CrisBalGrece version is good same with Cuoco92's version.
I myself left EUI ROM really fast and recommend OmniROM 7 Nougat. Performance is good, it has Vulkan support, Dolby Atmos and infrared app and it's the only custom ROM with official SafetyNet certification.
Thanks man, I tried Lineage, but still the fingerprint isn't working
I'll try flash OmniROM.
EDIT: I flashed that modem, but no luck. The fingerprint reader doesn't recognize anything/not vibration.
EDIT 2: I tried Resurection Remix and Omni and the fingerprint reader isn't working. It worked for a tiny bit then stopped again... how can I fix it? It's really frustrating as it's a gift for my wife and it doesn't work well The battery life is terrible too.
Again, I ask people don't root and stick to original firmware. It's not your phone. It's your wife phone. You just ruin the phone.
I have very good battery life. Half day still got 44%.fingerprint also work great. I have original Indian ROM 19.

As you were told before, you're not the only one using this phone. Yours is working perfectly? Then lucky you. A lot of people, who didn't root nor flash anything besides the stock ROM, saw their fingerprint readers fail. Then, once it's not working, it's understandable to try anything to recover it. And, for the 1000000th time, rooting doesn't break hardware on its own, and lots of Le Max 2 users have defective fingerprint sensors on a hardware level. Many of them solved the issue by replacing the defective sensor, and some of those users still have the phone rooted.
To sum it up, your comment doesn't help.

You can try a method which recovered mine for a while, although it died again. Let's hope it lasts in your case:
Let the phone on battery, until battery level reaches 0% and the phone switches off by itself. If you want it to be fast, you can try an app that drains you battery faster. I used one called "Your battery drainer", available from Google Play Store. Then, let it sit for an hour or two more, and charge it again until 100% battery level. Some people say that it's best to use normal and not fast charging, so before you drain the battery, make sure fast charging is disabled.
Once the phone is charged, turn it on and try the fingerprint again.
If this doesn't work, you may try to file a dispute through Paypal (if you paid through Paypal) and maybe you can return the phone and get a refund.
In case you want to do this, do not listen to the seller asking you to return to an address they give you, as there are cases where the seller later refused to acknowledge they had received the returned goods. Instead, escalate the dispute to a claim, let Paypal decide, and if they decide on your side, it will be Paypal that gives you a return address.
You then send the phone to the address provided by Paypal (with a trackable service) send Paypal the tracking number and when they have proof your package has arrived, they refund you. And, if eligible, they will even pay your shipping costs.

You didn't mention if you flashed an updated modem firmware. As I mentioned previously it is required to upgrade the modem firmware for the fingerprint sensor to work when the device is asleep for custom ROMs.
Please check my previous post for the modem firmware links to flash via TWRP. Flashing modem firmware doesn't require reflashing the ROM as it is separate from the ROM.

Yeah I flashed the Chinese 26s 05.09 but didn't seem to help. But draining the phone to 0% and charging it back up to 100% worked. Sometimes the sensor doesn't work, especially if the phones been sitting over night it just wont work for a while.
Also the battery is really bad on this thing, 1.45h of screen time and it's at 53%. I really wish this phone was stronger in those two points, but I'm feeling let down. I might send it back for a refund if another ROM doesn't fix it. Also what version/where can I download the Indian stock ROM I would need if I want to try that?
Thanks for the info above about returning it if I comes down to that.

No worries
Which model is yours? On the back of the phone it should say x820, x821 or x829
X820 is Chinese
X821 is Indian
X829 is international / North America
This thread should still have links to all three

Hello all,
I've been experimenting with custom roms lately. First I tried resurrection since it got lotsa attention and then I tried sensation, all causing the same problem.
I was lucky to have a NAND backup so I quickly went back to my stock rom. But now I am wondering why are these roms causing heating problems but not the stock rom? Interestingly, many people are using them without any complaints.
I thought this might be a problem with my phone. I contacted amazon and asked for a replacement, they were nice to replace the product even after 3 months! (kudos to them).
But now I'm wondering if this will solve my problem. Moreover, I sometimes had heating while charging the phone, bolstering my thesis that the phone is faulty. Any ideas anyone?
you returned your phone for no reason!
If it works fine on stock, phone is fine.
Learn how to use custom roms, read how to flash each Rom in their thread.
Basically, modem and kernel are related to heat. Plus one needs to wipe his/her phone completely at least once before going to custom.

Lol calm down! I've not returned it, I am going to replace it. I've had heating problems with stock rom as well, especially while charging. I've changed the battery, thinking the problem was the battery but it didn't help at all. Also today, after being back to stock rom, it still heats up even with simple tasks. So I assume there is some kind of fault.
It's normal for your phone to heat up. If it heats up its perfectly normal because the cores are working fine. If u got battery heating warnings or any other phone heating warning thats the problem and you should investigate =D
Hello,
I flashed my Oukitel K6000 Pro to Android Nougat 7.0, which was recently officially released on Oukitel's websites. Everything works like a charm except for fast charging. It takes literally hours to charge the phone with a charger that in Marshmallow charged the phone fully in few hours. I've found out that people using Samsung phones and some other brands have similar issue after Nougat update with an exception, though. Their Nougat's settings look different than Oukitel's. In Oukitel's there's no fast charging setting to enable, or disable the fast charging. I've tried to find some solution, but could not find any.
May anybody help me to fix this?
Thank you so far

Exactly, you're not alone in this.
From what I've gathered over Oukitel's official Facebook via comments, many users are experiencing this issue too.
But I've also found a great deal of those still running 6.0 have started to experience battery charging issues as well since the 7.0 update was made public.
Not sure how this is possible since their OTA app hasn't indicated any patches and hasn't updated anything that would lead to this issue happening on all Oukitel phones. Not just the K6000 Pro.
The funny side of it, You can't charge it enough to even do a flash...
This one user on youtube has found that their Oukitel K4000 isn't even drawing a charge when plugged in. (removed as new user I can't post links) watch?v=OvgN_QN5nE8

Hello,
I know few Oukitel K6000 Pro users, nobody has complained yet about the phone's Marshmallow charging issue. But anyway... This particular issue means the fast charging problem, particularly on K6000 Pro. The phone charges fully, it takes way more time, though, and it got triggered after the flash, to Nougat 7.0. I think it is a very specific issue, which has nothing to do with: 1. issues the users of other Oukitel's phones are facing (having its own specifics), and/or 2. with some K6000 Pro users' issues they face on Marshmallow.
I contacted right after the issue's recognition also Oukitel themselves. They responded, promising to make some tests in order to diagnose and potentially fix its Nougat's fast charging issue. Another K6000 Pro user, I know, received the answer informing him that Oukitel is aware of the issue, and that it tries to find out, where the cause is located... Let us see.
OTA update, any improvement for you regarding the fast charge issue?
Hello,
there's a new OTA update for Oukitel K6000 Pro. Did the update do any improvement for you regarding the fast charge issue? Not for me.
Thanks.
having the same issue here and im in the uk . Is there a way to downgrade or is it worth installing a custom rom?
I have never neither tried any custom rom for my Oukitel K6000 Pro, nor downgraded it, so I can't tell you. Nevertheless, I've discussed the issue continually with another owner of this phone, and we found out that a cable with a high current throughput may fix the issue. I may recommend Syncwire ~ SW-MC013. The connector of this cable is not as long as the original Oukitel's however, still holds in the phone's port quite well. ('Fast Charge & Sync - Cables are made with 23 AWG High Gauge Low Impedance wires which enable Syncwire cable to deliver up to 2.4 Amp current and transfer data up to 480 Mbits via USB 2.0. ' - https://www.amazon.com/Micro-Cable-Android-Charger-Super-Durable/dp/B01GFB1SLC) Also a good charger with voltage up to 9V may help. The original has, I think, 5V max.
My phone seems to have, though, issues also with the phone's port. Sometimes, with the Syncwire's cable, it's recharged quickly in few hours, at other times, it doesn't recognize connected cables at all, or there are short gaps withing the charging process, or charging takes way longer. SW-MC013 is being recognized the best from all the cables I have here and tried. So I would like to try to replace the port soon. When I have it replaced, I'll inform here, if the issue is really fixed. The other owner's phone stopped having the issues with the appropriate charger and cable (he's, actually, recommended me the Syncwire's SW-MC013 cable).

Hello, all, it's been a while. I'll add some story to this, hopefully useful. I actually changed the phone and gave my K6000 Pro to a friend of mine, who needed any better phone than hers, which K6000 Pro apparently was. She still has Nougat 7.0 (original stock ROM) on it and faces the same issue, but we're gonna change that. It's possible to make it charge faster with appropriate cables on Nougat, but it's still only a normal charging mode perhaps, running slightly faster, but definitely not fast charging. Lately I've got another K6000 Pro after a while for another friend of mine. I faced some charging issues, too, on its original Marshmallow Android 6 stock ROM. These issues were of a different type, though. I flashed it to Nougat to see what happens, how it reacts on a fast charger I've got from Oukitel to K3. This charger is way stronger than K6000 Pro's original. It offers 5/7/9 V mode, and 2 A. Its cable is also way more thick, and definitely supports fast charging. When I charged the phone with its original OS with this charger, it showed even a different graphic in its turned off mode, the same as on K3, and everything really went very fast. After the flash, including all Oukitel's updates, surprise, surprise, things got slower, the graphic stayed the same as in a normal charging mode. It was slightly faster, but definitely not that fast as with the previous OS. So I continued testing, and found this: https://www.needrom.com/download/oukitel-k6000-pro-6-0/ Here you can download the latest released Marshmallow stock ROM for K6000 Pro. There's also a specific version of software allowing you to safely downgrade the firmware to it. When I did that, the fast charging was right back. For this version of stock ROM, there's an update with basically one described fix: charging. After this update, all the previous phone's charging issues were gone. It started to fast charge again, works like a charm now. So that's it. I don't recommend the official Nougat stock ROM made by Oukitel, because they have never really dealt with its recharging drivers.
Unlock issue
After flashing my Oukitel to Nougat the phone needs ages to unlock, 7 seconds to be exactly. When I lock the phone and immediately unlock it again everything is fine but when it rests a few moments and I try to unlock it again it needs the 7 seconds to react. Same goes for calling. During the call the phone locks the screen to prevent some actions, when I put the phone away from my head it needs time to be ready again. Someone had that too?
I have it as a backup device and keep it in the bathroom to play music while taking a shower. Would love to find a slim, fast new ROM of 8.0

Is it possible to adjust volume in CrDroid Custom Rom Nougat 7.1.2 similarly as in MTK Engineering Mode? I guess it's not possible to start Engineering Mode in CrDroid Custom Rom Nougat 7.1.2 or any other custom rom, right? Without it, it's unusable.

MTKEM access is there but, available options in many cases are not working. I'm having phone's microphone issues, it seems to not work at all.
Speaking of CrDroid, after installing it with TWRP 3.0.2 (the only working from all versions I tried), the internal emulated storage is not accessible in both available versions on needrom.com.
Can you remember how to fix it?
I use a X829 4/64 GB and i recently noticed that i DO NOT HAVE ANY MOBILE NETWORK SIGNAL on Sim 1 (no data no calls). The truth is that during the last time i stopped using my le max 2 as my daily phone, so although i flashed many different " eui" roms i did not tried to insert my sim cards in the phone and try make any calls as i had no problem in the past. Yesterday i flashed AICP - Oreo - X2 (very good by the way) and this time i have the same problem with Sim 2. Some members have created similar threads in the past but i did not found any solution. I really wonder if someone here has any idea or any solution

I did not went back to stock. I flashed the zip when i was on latest Cuoco92 23s rom (coming from Oreo, as i was trying to find a solution) and then i flashed Oreo again. In both cases i had both sim cards wotking with a better (as i belieeve) network signal than the previous months i used my phone
I had the same problem with my network and the newest cuoco92 rom, but flashing the zip-file of andr68rus seems to have solved the problem! At least at the moment, the networks works again und I also have the feeling, the strength of the connection is much better than ever before!
Update:
The flash somehow only worked shortly. After a day or so, I had the same problem again. No network at all ( (neither data nor for phone calls), although the phone shows good network connetction! Strange.

For testing reasons i'm using the phone continuously for more than two weeks and i have not any problem at all. Considering that the network signal is better either at my home and at my work i believe that the zip from andr68rus made the "miracle". Of course i do not know what the zip file really did after flashing it (and if the better network signal is because of it) but i can "enjoy" the results

When you switch data from the one sim to the other it is normal to loose the signal for a while . It happens with every phone but normally the signal "comes" back again in a few seconds. I don't know if the zip will work for your problem but why don't you ask andr68rus "directly"?
So it's normal?
Yup that exact scenario. So if it's normal then I think it's ok.
I have already flashed this zip and now my data works better then ever. I have sent him pm but he didn't reply. Now you already cleared things up for me. Thanks for your response.
Can someone tell me does both sim slots supports LTE or not?
I am wondering if it might be possible, that this data connection issue is related to the battery status of the phone?
At least, with a fully charged battery fresh from the charger (for example in the morning), I typically always have good connection. The same when loading during the day. But then, and after a while without charging I loose connection or it gets more unstable at least.
Did somebody observe something similar?

It "sounds" strange. Personally i never had similar problems nad i think that this is not a common problem
I found that on a German website, the same problem that I observed concerning the network connection and the battery was also reported. For everybody able to read German, you find it here:
https://www.android-hilfe.de/forum/leeco-le-max-2-x820-x821-x822.2715/lte-bricht-zusammen-keine-verbindung-bei-akku-unter-60-mit-netzteil-ok.860971.html
They report that the network works very stable as long as the battery voltage is above 4 V. Once it is lower, the phone loses connection. If this is generally true, then this might be the problem in my case. With the phone coming from the charger, the voltage is about 4.3 V, but relatively quickly if falls below 4 V.
Is this purely a battery problem? Or could maybe some software modifications somehow help?

As mentioned in another thread, I have been experiencing the same problem when the battery level goes down to 70% or less (~4volt) the mobile network indicator still shows good signal but both voice and data stop working ie. cannot make or receive phone calls and no internet connectivity. But as soon as I plug in the charger, everything works perfectly.
I'm not responsible for any damage to your device of any sort.
By flashing this you take responsibility of anything that happens.
Process at your own risk!
If you want to check firmware - please make backup. Better to store all partitions, at least efs and may be modem.
The last 3 weeks we with @bonuzzz worked hard to make stable firmware for t820 and t825 tablets.
Finally, it's time for the first release.
Instructions
1. Install twrp
2. Download the zip(s) - firmware and Google Apps additional package (optional)
3. Backup all partitions (it least efs) and store somewhere - it need to do - because you can loose imei
4. Full wipe all
5. Flash firmware and gapps
Work
Almost all working

Thank to my good friend @bonuzzz
Thanks to LineageOS team
Thank you so much
I hope the ROM is always better, as soon as I have some time I install it to report any bugs
Thank you very much!!!
I really dug the samsung apps for the s-pen. is there a way to install them after installing lineageOS? (sorry for the newbie-question)
Hi,
i've installed the ROM yesterday and i used it today in case of a working day.
I have noticed that he unfortunately does not switch to LTE - despite full receipt. The tablet uses at most HSDPA, which makes the ROM for me currently not really usable.
It is also a bit slower than the stock ROM, but tolerable - only the network connection is still a hindrance.
I bought the tab because I thought, as a flagship this device will surely get the lineage OS.
I am still very enthusiastic and really thankful that someone has made such a great ROM for this tablet- many many thanks to the devs!!!
regards
Ralf
Edit: after reinstalling this ROM is found the switch to change the preferred connection type to LTE. So i go on using it

For the 820 the GPS is not working.
Can we expect the same with this 825 version?
Thanks for your efforts!!
Ok so, I gave the rom a chance and to be honest it works quite well.
Kudos to Valera and Bonuzzz for the effort, this is looking very promising.
I don't use the S-Pen nor the phone-calling stuff so, my experience with this build doesn't include those two.
General usage feels snappy, I only had some trouble while playing video streams on the stock browser and firefox. The problem went away while using chrome.
Tried a couple of HDR 4K files on MX Player and they seemed to play nicely.
Played around with the settings, everything cool.
The only problem so far is a huge battery drain during normal usage.
Aside from that, this is an excellent beginning.
Considering this is just a 1st release, it's very stable.
If you need any kind of testing, I'm more than willing to help.

kainanmaki,
Thanks for the initial testing. I have not flashed this ROM yet. I'm still observing a bit before I do so.
I'm curious, how do you define normal usage? Also, are you able to quantify the huge battery drain?
Thanks much!

Well, you should. At least it could give you a good idea of what to expect when the rom is ready.
I have never used lineage on a tablet so I wasn't sure what to expect.
For starters, normal use is just what you can imagine, youtube, chrome, mx player (hdr stuff), headphones, couple of silly games.
After checking how stable it was, tried Xposed -sucessfully- and every module worked fine (amplify, bootmanager, rootcloack, xnotify,youtube adaway). The drain is severe, you could literally notice the % going down ridiculously fast.
What's worst, my normal app usage and settings are designed to not duplicate what I can already do on my HTC 10.
So no GPS or Bluetooth, almost no applications doing sync stuff that I already have on my smartphone. (Gmail for e.g)
I always force wifi to sleep when display is off. Again, I don't need another device duplicating my smartphone.
LTE data is also off most of the time (and LTE works as expected per Speedtest -70 mbit-)
But again, settings are tweaked to maximize battery, while using it and while sleeping.
I have used BetterBatteryStats to take some measures, the drain is related to the core of the OS services.
A simple comparison with Stock. I just have started debloating touchwiz (very happy with the progress there too TBH), and barely scraching the surface of what can be done on stock, BBS is reporting 6.25 minutes per 1% of battery. Roughly 10 hours of battery of non stop use. After removing 85% of Samsung bloatware and its services, it's going to look even better. Samsung never ceases to amaze me with their never ending junk. So again, the rom is not ready for primetime. But that could change fast.
IMHO, you should install TWRP and do a backup of stock stuff and take a dive. Even if Lineage feels like android for smartphones, still works wonders. And you can go back to touchwiz in 3 minutes...
EDIT: Forgot to quantify the drain. The android energy forecast estimated 3-4 hours for a full charge. Closer to 3....
i wish there was developer who would give us debloated, tweaked stock rom .. i know this is not the right thread for making this post, but still

Wrong place to post as you already know, debloat the rom yourself.

Sorry Carlo, I was confused, mine is SM-T825N.
I got it wrong, when I took a look at your download mode pic it became clear.
I don't have the CROM service stuff.
Still, did you try to flash it with the FRP Lock off?

To disable FRP Lock, you have to enable OEM unlock in Developer options.
I am using Pocof1 March2019
lately,
1. it lags alot
2. heats up alot
3. freezes on touch and even applications doesn't work as swiftly as before!
now i have done the following
1. tried three different kernels after CLEAN flashing Roms such as Corvus, Crdroid, havoc , of Android 9 and 10 both and tested performance
2. device was running on Lawrun for last many months various updates on Pie rom
3. I FORMAT data and Reflashed MIUI11.0.8 by Fastboot method, clean flashing fully
4. I then format data again and changed by filesystem to f2fs
using now AEX / pie with sphinx3.1 and barely making thru day
device heats alot even on room temperature while ac working.
it is possible the cooling mechanism is deat? or thats the end of this device for me?
any sugggestions? before i go to market and start hunting for some other developer friendly device?
on same node, can one suggest me another Xiomi (LED panel only) which is very popular on xda , having many kernels and roms?
thank you in advance guys
Well if you've done all possible ts software wise, then it's likely an issue with hardware. If it's just heating issues depends on what you're doing. If you have a case, depending on thickness and what you are doing then it would cause heating problems and also if the phone overheats then performance dips.
In my case haven't had issues with the phone at all performance wise, battery, or anything else (only problem is signal, but that's an issue with my network, not the phone per se).
So based on my humble opinion, try having it checked for damages. Since it's out of warranty have a technician check it out, most technicians provide free diagnostics anyway, or if you're confident enough try opening the phone yourself, ifixit has a tutorial on it and unlike most phones it's an easy teardown. But if you're not confident look for a pro who offers free diagnostics first

thats a very logical answer sir!
however i have to buy another device because any repair person wont just fix device in few hours and data will definately be lost !
btw
after restarting device works perfect for some time
its just later suddenly it starts lagging and till i restart
i am currently on AEX 6.4 / sphinx3.1 (pie / aug2019 patch)

You are using android 10 firmware with android 9, why ? If you use Android 10 with older firmwares than 11.0.4.0 it will cause issues and so is your case, just in reverse. Try to flash 11.0.8.0 from fastboot. Then flash recovery > AEX 7.3 + gapps. Or try Reloaded OS. It is a CAF rom so performance is great with good battery backup. You won't need any custom kernels. If no progress still then get ready to say goodbye to your poco.

You're confusing bro. As for data, why not just back it up? You yourself even stated that you've formatted, flashed and all that stuff right? So basically by now you have no internal data or you already have a backup. And as I said dude just have it inspected, they should be able to perform a checkup within the day if they aren't that busy. I've had issues before and in my country some where able to diagnose the issue.
FYI that's your problem if they can't diagnose it in a few hours, if you badly need the phone repaired then prep for it, "diskarte" as we call it, that means planning ahead in my country. Make plans and prep for it, either borrow an old phone from a friend for the mean time while you have yours in repair or something or ask maybe the repair guy has a spare dumb phone (some OEMS do that if you are in warranty anyway) or tell people not to call you on a certain day because you need to have the phone repaired.
Again, that's no longer my issue "diskartehan mo" make your own plans. I'm saying if you tried all software then it's hardware. If you don't want to go through all that hassle then just buy a new phone, simple as that

the reason why i am nervous here, locally there arent any good repair shops who can fix Xiaomi Devices. mostly go after iphones or samsungs hence i am pretty positive any repair shop person will open device, ask for something to be replaced and it wont matter
I'm on latest MIUI 11.0.8.0 with No Gravity Kernel, with NGK thermals. Performance is superb and runs very smooth. PUBG runs at constant 60FPS even on HDR + Extreme (used GFX tool).
CPU throttling test app provides results of 170K+ GIOPS. On stock MIUI kernel, this result doesn't cross 100k and even PUBG is not playable when there are many players nearby. Constant stuttering and lag.
You should try fastboot flashing the latest stable ROM and a custom kernel (NGK, ODK, Lawrun etc) to check, as stock MIUI kernel is laggy anyway. If everything is fine in hardware, this setup will provide you with Max performance.
My phone makes two years this november and it still gets 360k on antutu on same setup and never gets heated
*Changed the battery two months ago eve it didn't have any problem
