I've tried 3 different Nougat ROMs on my LEX727, and all 3 always say 50% battery and won't charge, except in TWRP. TWRP reads battery % correctly and charges fine. What could cause this, and how do I fix it?
EDIT: MM ROMs work fine, it's just Nougat.
have you make your all wipe ?
Works for me in LineageOS 14.1 which is nougat-based.
My friend also has several appear such problems, some AICP some omni, heard that brush back official 20 s, brush again 7.1 native-like seems ok, can have a try if you don't bother
I have the same issue on AICP since tonight. my lex720 stuck on 39% and can´t go higher. I tried 2 different charger and cable but doesnt change anything.
Hi there, first off please forgive me if I get any terminology wrong - I've been learning way more about this than I ever intended...
I have a Galaxy Note 4 (SM910F / trltexx) that's causing me problems with custom ROMs - the phone gets to various points of the startup process, then either shuts off or reboots.
I'm posting this in the Note 4 forum as it happens with all the following ROMs:
- LineageOS 14.1
- Resurrection Remix 5.7.4 / 5.8.0 / 5.8.3
I assume that either there's something screwed up about the phone itself, or I'm missing something fundamental about what ROMs I'm installing.
When I first install the OS (adb sideload), it will boot up the first time around just fine.
On occasion (with all of the above) the phone has gotten all the way to the initial configuration screen (e.g. select a wireless network). I've tried all types of wipe and format/reset, both clean and dirty flash, no difference. The point to which it gets in the boot process seems random. When the phone is connected to a charger, it will try to reboot. If it is not connected, it just shuts off.
Stock Samsung firmwares (5.0.1 and 6.1.1) with stock recovery all worked fine.
Recovery is TWRP v2.8.7.0 (that's the only one I could get running, 3.x would not start up)
I've recently had the screen replaced, the shop did a poor job (my proximity sensor started acting up, I first tried replacing it, then tried the electrical tape spacer trick, which worked.) I'm also using an aftermarket Anker battery, for what it's worth (they're great, btw).
Any ideas? As mentioned it seems to boot ok with stock firmware, but I don't want to run stock because that's no fun.
Thanks for any ideas!
I either have to be really stupid or brave to flash a off-model ROM for my device. The ROM was Lineage 14.1 intended for Note 3 SM-N9005, but I tried it anyway. And it works. Everything works fine as well as flashed GApps for Nougat 7.1. But the only thing refuses to work is my USB port.
The phone was running so low on battery so I tried plugging in, but it did not trigger OS's charging status. Though it does charge, I found out later. I turned off my phone and let it sit there plugging into the wall and later on reboot to realize battery does go up. But charging is still not recognized. PC does not recognize the phone either ( and therefore adb doesnt work/recognize the device ).
Some research I had lead to the stock kernel its having. What should I do now? Flashing a new kernel? What should I flash? Is there even a custom kernel for this phone and supports Nougat 7.1? Because all i could find on the internet are kernels for Android lolipop and Kitkat.
See development thread for kernels .Read roms thread .

The custom ROM were Trader418's. Somehow if the kernel doesnt work at all, it would have got bootloop. But it works perfectly fine. Just exclude the derpy USB port that refuses to show its charging.
Synergy kernel problem
I installed resurrection remix nougat in note 3. It works fine but when I install synergy kernel I face bootloop problems. Kindly help me to fix
Need a little help with my X727, after i got it i flashed emmc_appsboot.mbn to unlock the bootloader, flashed TWRP and the latest lineage build which was the July 21st at the time. Everything was working perfectly and then a few days later i updated to the July 28th build and the battery indicator got stuck at 50% and it wouldn't charge the phone when plugged into the wall charger. If i booted into TWRP it would charge, but when i power it off and plug into the wall charger the battery charge symbol would come up and then orange LED comes on like it's charging but it's not. Now the issue is i foolishly let the battery run down, i left it plugged into the wall charger overnight but can't get enough juice to even get it to boot into TWRP. Any suggestions or should i cut my losses and return it?
Update: I left it charging for a little while with no change, decided to try to power it on again. I held down the power button and vol + button and plugged in the wall charger, held them down for about 15 secs and it finally booted into TWRP and is currently charging.
Now i'm back to my original problem the phone won't charge normally, have to boot into TWRP and is stuck at displaying 50% for battery.
Had any luck with this? Somewhat in the same boat as you.
Got a x727 new recently. Had the 18s software. I went straight to flashing the aBoot with unlock the bootloader file, flashed TWRP and putOmni first. Since then, battery doesn't update in android and just says 50%. Now currently on AICP.
There are times where if I go into TWRP it shows a different number other than 50%.
Thinking I may go back to stock ROM but keep unlockboot loader and somehow update to 21s and then go back to custom ROM .
Anyone got ideas/thoughts?
I have the same problems with nougat roms as you, i was running lineage 21st july update fine and then with 28st july i have that battery problem where the percentage only shows 50% and wont charge.

Good observation:
I tested that out and your right. I can install July 21st build on a clean install and charging works and battery is displaying anything other 50%.
If I install July 28th's build, charging doesn't work and battery is always at 50%.
Adding @jrior001 to the conversation since he helps maintain Lineage for our device: Any thoughts?
I have x727 FYI

Thanks for your answer, at least i know i'm not alone. Do you have as me the same problem with battery in other nougat roms? I tried omnirom and aicp and had the same problem.
I think it is kernel related because when i flashed blackscreen kernel in lineage 21st july i had the same battery problem as i had with 28th. I can't figure out if it is because we have a hardware or sofware problem.

Well so far it's you and me.. no one either has a x727 phone and/or we have the wrong something, somewhere.
I flash AICP or Omni and same issue.
Both AICP and Omni use blackscreen kernel? Lineage 7/28 and after doesn't work for me.
The only thing that works is PA and RR. Assuming they are Lineage base, their latest release predates 7/21 so maybe that's why those two ROMs work for me.

From time to time i read here people that have the same problem but they just flash again stock rom and forget about it. I have x720 china version so this could happen in both models.
Reading in internet about this problem some people got it fixed with battery calibration, others with battery replacement and others had to change the motherboard. The problem is we can't try battery calibration because charging is not working so we can't let it dry completly.
About kernel i'm pretty sure AICP use blackscreen but not OMNI, in 28th july lineage update log there were a few changes to kernel and that's what i think it's causing our problem. Regards!

Yeah I don't know what else to do.
I even restored to stock again. Went back to x727 19s. reflashed modems to the 19s. Relocked bootloader, did an official OTA update to 21s. unlocked the bootloader, installed official TWRP, and tried flashing latest AICP and still same thing! I know i have 90%+ in battery..
Don't know what else to update and/or change that could affect this? I'm assuming other x727s that were on 21s are not having this issue went trying to flash AICP or Omni.

I'm starting to think it's hardware problem ( motherboard or battery ) but as we don't have this problem in stock rom we can't use our guarantee. Please tell me if you have any advance.

IMO I don't think it's a hardware fault. I think it could be a hardware incompatibility, maybe a hardware revision that no has anticipated yet.
I can only assume that when I went back to stock x727 19s and relocked bootloader and took the official upgrade to 21s, that my phone IS stock at that point, and re-unlocked bootloader and proceeded with the rest. I haven't flashed anything out of the ordinary afterwards, twrp and just been trying ROMs since.
I know if you go back to Stock Rom or Turbo Rom which is MM, no charging issue there.
As of this post date, AICP, Omni, Lineage 14, Tipsy, Tesla with their latest builds, do not work. I will only assume these ROMs either use Lineage and/or use Lineage as their base and they cherry pick certain things either kernel commits, or fixes (or breaks) and thats why maybe these ROMS don't work for us.
Resurrection Remix and Paranoid DOES work. Not sure what they do different exactly but I would be curious if they update their ROM soon, that it will break charging like the rest.
I also have been reading throughout the forum about within the last 30 days, people have been posting about charging issues or their phone stops charging and it could possibility be a bad charger. I wonder if those folks were on the ROMs listed above and did an OTA update and that broke charging. (FYI the USB-C cable that came with the phone is crap for data connection or at least mines was. Only good for charging. Had to use my own USB-C cable to connect to my PC)
If people have issues with charging, if you can charge your phone with it turned off and at least get it to 15%, get your files prep, jump into TWRP and flash to those other two working ROMs, quick charging should work and battery reporting will work again. I'm personally back to RR again.
We need help/direction from a DEV because this is beyond my skill set. I don't even know where to start or what logs to give.
@chuchorra - Assuming you were using just using plain lineage, you can extract the boot.img from the 7/21 zip file and just flash the file to your phone and that should revert back the kernel or whatever it is that is screwing up charging .
I did a test where i installed the latest build and got the issue, but i was able to fix it but reverting back to the 7/21 boot.img file which kept charging and battery display working.
Had a similar issue of being unable to get over 50% charge but deleting BatteryStat.bin (and other Battery****.bin files) in /data/system/ seemed to fix this problem.
But now have another problem, the phone doesn't seem to charge when switch off! The charging indicator comes on but when I switch the phone on in the morning, the battery's still low.
Nice! But what are the implications to use a boot.img from a previous update? Maybe we should post in lineage official thread to ask what logs are needed.
If it can be useful to someone, the USB c plug of my original stock cable on one side charges fast, turning it on the other side charges slowly I have marked the fast side with a red point, just to known! Cheers!

None that I can tell so far?? I think tried posting but nothing but crickets there...
Might try erasing that battery bin file on the broken rom

Tried it and no luck. There was only two files in that directory, batterystat.bin and battery(something).xml.. delete one, and then tried deleting both and status didn't change on it.
I tried that, it's manual battery calibration but didn't help. Maybe there are more than those 2 files. About lineage official thread i post there too but anyone had the same problem, but now that you found flashing old boot.img fix the problem they could know where is the conflict. Cheers!
I have a similar issue, was on linage, with no issues, and slowly but surely charging started acting up after 4 months of no issues. First the phone RED LED would be on (charging) but the OS wouldn't see it charging, AMPERE would not show charging even though it showed AC adapter connected. Figured it was rom, updated to latest and now i have no charging or connectivity. Shows 50% charge, then back to ZERO. Still under warranty, not sure what to do as LEECO web site is down, will call on Monday and see what they say.
i have 2 leeco. both the same but from another seller. One have this issue and the second is working perfect.
Not saying this is the solution but I had a problem with fast charge and sometimes wouldn't charge at all, on both PA and LOS roms then I switch to a LG cable re-downloaded everything re-transferred the zip files to the phone with the LG cable and now it fast-charges it with no problem on LOS. I even started a thread warning about the Leeco cable.
Few months ago i rooted my lenovo a6000 plus and installed resurrection remix os on it (it was working very fine) all thanks to the developers, all the instruction provided was very clear and no problem was found and that time.
Now i wanted to change it to near to stock rom so few days ago installed LINEAGE OS which didn't work out, later i tried with SLIM ROM and AOSP EXTENDED non of them worked so came back to RESURRECTION REMIX but every time i install any of the OS my phones goes to the boot loop after few minutes of use (i don't think there is any problem with any of the OS) . But if anyone can help me in fixing this boot loop it would be great.
ps: all the OS is supporting and working fine. I have also installed HEX-FIRMWARE-PATCH.zip
thanks in advance........
is the phone in bootloop or it is just restarting???if it is restarting try another battery.A month back I tried a variety of ROMs in my LENOVO A6000 i also had the same problem may be this might help you and i am not sure that battery is causing the loop
