Oreo update question - LG G5 Questions & Answers

Hello guys! To those that have installed Oreo how is the battery after using it for a longer time? I installed the Open EU kdz file via LGUP but my CPU was at 70-85°C almost all the time and my battery SOT was about an hour. Should I give it another try? I went back to Nougat after trying it. I only used Oreo for about 12 hours when I reflashed Nougat. So what do you think?

Onlock bootloader, flash twrp, root, flash Nugat zip file .

Le Max 2 update from 5.9.023S to 5.9.026S failed

Need your help.
My Le Max 2 is running 5.9.023S stock rom at the moment. Recovery has been changed back to Stock recovery (previously is TWRP).
The Rom update keep prompting for new Stable version 5.9.026S but when I follow OTA update it download, restart to Recovery try to update and Failed with Status "Failed to Update".
I even download the Rom file, change it to update.zip and do manual flash but still failed.
Can you guide on how to update this version?
Thanks a lot.
First flash TWRP back via Fastboot. You can flash the any stock official update 26S use TWRP just flash it normal as other custom rom. Note your current TWRP recovery will be replace by EUI stock recovery so you will have to flash TWRP again after installed 26S by Fastboot/other way.
I have a problem like that and i used TWRP (fastboot boot twrp.img) and flashed 23S again to restore some chinese apps that i removed earlier.
Then i updated without any problem to 26S.
The OTA update verifies the checksum of the modem, bootanimation, boot.img and so on. So, if you altered/replaced some of these, the updater script fails. Flashing the entire 23S from scratch obviously put all the correct files in the right place.
Where do you find the official 5.9.026S?
My phone is running on 5.9.023S and tells me its up to date.
Also on the Leeco homepage is the lastest 23S.........
I need some help also
My phone x829 arrived with 16s
I swapped some custom ROMs with twrp and at the end I finally installed the official 20s and I choosed to replace twrp with custom recovery
The problem is almost 2 months now and I don't have any message for ota update for 23 or 26s
What can I do?
Thanks in advance
16s is the last available rom for x829. To see updates coming, you must firstly flash a chinese rom
That's what I m saying
I have flashed and installed the 20s this is the Chinese rom,but since then I have no ota,2 months and no ota
You are right. I try to flash it back twice and now able to update to 26S. it works fine now. Thanks a lot.

ERROR 7 while updating lineage OS

I had downloaded latest version of lineage OS from official website and I tried to flash on my REDMI Note 3 Kenzo but I can't here is the screenshot attached of remark.
Pls help
I was just about to post about this. I have the same issue, a work around I found was described in this video: https://www.youtube.com/watch?v=bGVOR0kugZw
However, now that I have it installed, and try to OTA update, I get the same, I have to repeat the steps in the video every time I update, kinda frustrating and unnecessary imho. I had the latest MIUI updated and unlocked with the miui unlocker before the wiping and installing. All I have found its related to the bootloader not supporting android N.
Look at the error and you will see the issue.
Your firmware is too old.
Download one from Lineage thread and flash that before Lineage
update, I installed the firmware from this thread: https://forum.xda-developers.com/redmi-note-3/development/firmware-hmnote3proglobal-t3574361
now update goes thru like its supposed to
every recovery i flash gives me ERROR 7 :/
i have a 'kate' and befor i used to flash roms without issue. kenzo roms and flash kate modem done.
but phone crashed some months ago so i changed but now i want it again. and now im back on did a edl flash miui beta unlocked bootloader flashed twrp (all the twrp possible btw i tried all i could find) they all dont want to flash a custom rom i tried 7 different ZIP of custom roms... i tried to flash 4 diffeeent versions of RR 5.7.4 and 1 RR 5.8.4 all give error 7. flash kate modem. still error, then flashed modem with emmc thing patched nope still wont flash any custom rom
does anybody know how to fix this
You have to erase dalvik cache and DATA it will bring you new setup but still your device would be updated....

Can't downgrade KIW 21 from B370 to B350

Can't downgrade my Honor 5x from B370 to B350, which is obviousely required before flashing Lineage OS.
- A lot of Guides write that the downgrade should be performed with the Android Update App, then choosing "local update". This doesn't work, because this "local update" menu option is no longer available on B370 Firmware.
- Other Guides write to put the "update.app" file with the old B350 firmware in a dload folder on the SD card, then to restart the phone by pressing both volume keys and power key at the same time. When I'm doing that, the package is verified, then the installation starts, stuck for about 2 minutes at 5%, then the phone reboots without any message, and nothing happened. The Honor 5x is still on B370.
Any advice? Have tried different B350 Packages from different sites. Has anyone a link to a B350 (or to another old Firmware that works for a Linage OS installation) that is proved to work for downgrading B370 on KIW 21? Thank you all in advance for any help.

Try this maybe
Someone posted patch to use customrom without downgrade
In slimrom thread in dev thread
"Someone posted patch" is very unspecific. How should I find that patch? Thank you in advance for any guidance.

So what is the recommended upgrade procedure for installing Lineage OS on Honor 5x with Stock FW B370?
1. Flash Lineage OS over B370
2. Flash this Patch
or is it the other way round?
It's disappointing that there is not anymore any guide that works. It's impossible to flash any older Honor 5x stock firmware version. It doesn't work with the Honor update program (local update option is no longer available), it doesn't work with power+Vol-Up+Vol-Down (phone reboots at 5% without installing anything), and it's also not possible to flash a Honor firmware zip with TWRP (Error 7).
What's intresting is that only Lineage OS warns that a VoLTE FW like B370 has to be downgraded before installing Lineage OS. All XDA developer sections for all the other custom ROMs don't mention that a VoLTE FW has to be downgraded before installing the custom ROM.
- Has anybody successfully installed a custom ROM on a Honor 5x without downgrading the VoLTE FW before?
- Is this downgrade only required for installing Lineage OS, or is it also required or recommended for installing any other custom ROM?

×You need twrp first, custom recovery then before anything backup nandroid first then follow normal custom rom flash processus and for volte it seems you need to flash patch after ROM.
If it boot bingo, then flash gapps, magisk whatever you want.
×Los say it but it is known for every ROM
×Seems @lineu94 giving the patch has successfuly used it.
BUT: some say to not flash what you dont know.
Im not responsable for what will happen.
Nore lineu94 giving the patch.
May be PM him to know where he got patch from who......
If it works, give him credits and thank him for useful comment and zip
Thank you all for your help.
The patch file that you mentioned is for a Honor 8 device.
In XDA Forums, there are at least three threads that describe how to downgrade a Honor 5x from B370 to an older firmware with the three different methods that I have all tried and described here, and not one of them works in my case. My Honor 5x is my primary phone, and my old Galaxy S3 is used by my wife. Since there is not one documented description that works, it's too risky to me to install Lineage OS or any other ROM. I can not take the risk to break my device because I'm using it.
Will stay on B370 stock FW and live with a laggy device and the problems (Exchange Email and Bluetooth) and the missing security patches.
I'm very disappointed from Honor: They promised functional updates for at least two years and security updates even longer. That was one of the main reasons why I have bought the Honor 5x. If Honor wouldn't have lie to their customers, we would have Andoid 8 on our device today. Instead, we have Android 6 with the last security update from March 2017. My next device will be anything other than Honor or Huawei.
Took the risk to flash Lineage OS after a successful Bachup from TWRP recovery to the SD card., and was finally successsful! But it was a lot of "try and error". What worked for me:
1. Performed factory reset in TWRP, and cleaned dvalik/cache, Then, I flashed Lineage OS, the ZIP file that was mentioned here and open Gapps in this order. Then performed factory reset and clean dvalik/cache.
2. The phone restarted, but landed in some kind of Huawei Recovery. Could restart the phone several times, always landed in Huawei recovery.
3. Rebooted the phone with pressing both volume keys and the power key at the same time. It booted into TWRP recovery.
4. Reflashed Lineage OS and Gapps again without the ZIP file. Performed facory reset again.
And hurra, the Honor x booted in Lineage OS

Does It still working for you? I will try to do this on b360 firmware
Yes, I'm on Lineage OS and the 5x is still much faster and I like the features.
But there is no more Development for the Honor 5x. According the Honor update promise, our device should be on Oreo today. And Huawei and Honor just stopped releasing unlock codes for the bootloader. It's very important that customers that want to use their device for more than one year stay away from these two brands!
I also succeeded to install Lineage OS on B360, all what we must to do is install again from TWRP. Everything is working

Unable to boot my kenzo into a Nougat based rom. Only NXExperience 10.4 booting up.

I have the permission for unlocking my phone.
Actually, I was running NOS 7.1.2 and was having signal problems, so i decided to flash official los 14.1 firmware by the strix.
And the bootloader was eventually locked, but after running mi unlock many times, the bootloader failed to unlock.
So, i used miui 10 via mi flash (accidentally used the option clean all and lock), got error 20091, when adding my account.
Now, i flashed miui 8.0.6.0, unlocked my bootloader using unofficial method, and finally it got unlocked.
Now, I have an unlocked bootloader, twrp installed. But, whenever I am flashing a marshmallow firmware along with Nitrogen OS 7.1.2. I am getting a bootloop, even after removing the emc app boot file.
Funnily enough, after flashing NX experience 10.4 marshmallow based rom and NX radios for kenzo, I am able to use my phone, albiet on a Marshmallow.
Any help on what could have occured and what can I do now. I just want to run a 7.1.2 based rom. Which firmware can I flash.?

Who told u flash firmware with every rom ?
Firmware is flashed only once. Not with every rom u flash.
U can unlock phone on miui 10.1 stable. There is already thread to unlock phone zcx twrp method in guide discussion thread. U dont need to go 8.0.60 version to unloock phone to install twrp.
And those nx radio zip u flashed. Who using those?
just make sure you have officially unlocked on miui marshmallow

No access to stock roms

I am still not able to install latest lineage without bootloop see here:
see older xda thread
so this weekend I thought well give it a last try before selling my unlocked H850 on ebay. I want to flash it back on stock rom and do the whole process again - maybe flashing this time a different custom rom(15.1 unofficial).
The problem is it seems stock rom is no longer available.
See here
LG-H85010E-Flashable.COMPLETE.zip -> download speed is very slow and I wasn't able to finish download successfully (always connection errors )
H85010e_00_OPEN_EU_OP_0817.kdz -> get no access to this file (has LG stopped service?)
can be closed solution was first flashing Android 8 stock rom with uppercut (H85030f_00_OPEN_EU_OP_1122.kdz) than flashing custom rom based on Android 9 (lineage-16.0-20200811-X86CPU-h850 - thank you to the author) and than I was able to flash official lineage 17.1 than bootloop was suddenly fixed. Each time after flashing I just did normal wipe (confirming with yes).
official tutorial completly sucks:
https://wiki.lineageos.org/devices/h850/install
-> sideload is not necessary and when you come from older Android Version you have to flash Lineage 16 before (no evidence and no image in download section).
