Remember you have to reformat after installing twrp.

It took me only two minutes to find the new twrp.

20 reboots without issue.
[Samsung Galaxy A8 (2018) Questions & Answers] VDavid003:
You mean wiping data right?

'cuz that's what's failing on the screenshots.

For me the first about 12 hours was normal, then the freezes and bootloops started happening.
[Samsung Galaxy A8 (2018) Questions & Answers] VDavid003:
So it didn't fix the bootloops, but at least TWRP works now!

I was able to install TWRP and root with Magisk when the pie update was uploaded on this forum.

And yes you need to erase everything
[Samsung Galaxy A8 (2018) Questions & Answers] VDavid003:
Well, I was able to root and fix twrp, but I still get bootloops and freezes...

I think I'll just wait for pie to be released on my csc and until that, I'll either get used to it or go back to Phh-treble (I've never tought I'd say a custom ROM that is not even meant for this specific device is more stable (for me) than the official)
[Samsung Galaxy A8 (2018) Questions & Answers] mindlery:
I am having the exact same issues you are. In fact, are you using my phone when I sleep?

If you want to try out a 9.0 gsi that'll run pretty darn good in the meantime, try aospext's 9. Works well enough to use daily and you'll get a "4g" constant connection.

And since you have the same issues, this should give you a flawless run. If you are just entering a clean treble, wipe it all. Everything including internal. Just not your emovable of course.

Flash the vendor in from A8 that says 8.1 and 9.0 compatible. Flash the .img. Reboot recovery flash vendor again and then gapps. I did magisk after a normal run through and the latest was a 50% pass on safety. Gonna try it again right now for a third time. No issues with booting at all. If you do it differently all hell breaks loose and you'll be booted but with a severe case of "no system webview syndrome" or "chrome ain't no system app useless-lee-itus" The force closing of apps could be mistaken for an old Atari video game..

Well, it's good to see it's not me being stupid or my phone being broken :D
[Samsung Galaxy A8 (2018) Questions & Answers] VDavid003:
Soo.. looks like I fixed it.. What I did is downgraded to stock 8.0 and let OTA do it's job. I know it must have updated my bootloader (thus adding new locks to my device) but so far no bootloops,freezes, or anything. It might have been the bootloader, or the modem, or idk.
[Samsung Galaxy A8 (2018) Questions & Answers] mchlbenner:
Their where no freezing or issues on Oreo.

Android pie was released and it would freeze at boot and watching videos.
[Samsung Galaxy A8 (2018) Questions & Answers] VDavid003:
What I meant is that I let OTA update my 8.0 to 9.0 and the freezes and bootloops are now fixed.

[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] tijoro:
Hi,

I just wanted to shout out that your work makes a difference. I was in the market for a privacy-friendly, daily driver phone with decent specs and good LineageOS support. I preferred a Mediatek because Qualcomm's iZat location service / indoor positioning service transmits your position to Qualcomm, possibly at the firmware level where it is hard to disable. Yours is the only complete LineageOS for any good Mediatek phone.

However, I live in an overcrowded 2G/3G cell and therefore need VoLTE. At the time, I didn't yet see your comment about fixing VoLTE. I've repeatedly had issues with VoLTE working in India but not in my country. Then somebody confirmed that the Pocophone LineageOS can do VoLTE where I live. I ended up buying that, but it really was a close call.

Thank you for your work.
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] softmaster3:

Thanks alot to the developer.

I'm using this rom (15.1 version). No major bugs. ROM is stable.

Hoping more updates to this rom.

Or possibly a lineage os 16.0 stable update someday :)

What are the improvements over the original Rom?
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] Amanpandey1999:
Help

First of all appreciation to the developer for his work.

I'm using this rom (latest built).

The rom is fine.

But I'm facing issue regarding mobile networks.

The networks just disappear after some time and I have to restart the phone in order to use mobile network.

I am using Airtel sim card.

I used (31st May 2019) version for a day with no network issues. I had flashed Pico Gapps that time.

Currently using (1st June 2019) version and flashed Stock Gapps. The phone just turned nearly to Pixel OS :good: . But I'm facing network issues with this.

Hoping for a new update soon to fix all these bugs.

one more request, if developer could add the stock lenovo k8 note camera or the Google camera to this rom.

I know its difficult to port Google camera in MTK devices.

[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] M.A.P:
Follow the instructions properly and if it still exists then post screenshot of the error
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] M.A.P:
Do a reboot or two. If it still exists then.. use fastboot to flash all images except boot.img, system.img, cache.img and userdata.img of the latest Stock. Basically flash modem images.

I feel the camera is better than stock
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] Amanpandey1999:
:silly:

Tried flashing all images (except system, boot, cache, userdata, recovery) through fastboot but the network problem still persist.

As I told I am using Airtel Sim card, the networks just disappear after some minutes, then I need to reboot in order to get network, and again after some minutes network disappears again.

Screenshot : https://ibb.co/Ypry1Kq

[IMG="Screenshot"]https://i.ibb.co/t8dxvNW/Screenshot-20190604-200347-Pixel-Launcher.png[/IMG]

I had also flashed Stock Gapps zip, su zip (for root access), Dolby atmos zip, Youtube Vanced zip files. Just thought I should mention.

The experience using this ROM is very good, but for now I'm switching back to stock ROM, as network is major priority.
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] M.A.P:
Ok wait for my new build, it is most likely a problem with modem images
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] Amanpandey1999:

Problem flashing gsi. Can anyone list some android pie gsi
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] Anas Rahman:
Search : *rom name* pie gsi

Select 'A only' from downloads
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] yoyovid:
Thank you so much for ur quick support but I flashed some a only ROMs and the only thing I get after reboot to system is fastboot mode.Have tried many a only gsi.
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] Anas Rahman:
Hmmm, I'm assuming you got Los 15.1 working correctly. Then follow this :

Make sure Vendor is mounted in TWRP, then wipe system... Then flash your gsi image as system image... Then reboot once, if you get encryption error then reboot to recovery and format data once. After you boot to system, set up your phone then again reboot to recovery and flash gapps
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] M.A.P:
Don't wipe vendor, just don't
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] Anas Rahman:
OH, okay.... It was written in the instructions iirc

Or maybe I confused it with Los steps
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] M.A.P:
Yes we need to wipe system and vendor after flashing the repartition zip and rebooting. Cause it is repartitioned, and we need to format them to ext4. Which I can't in script cause the partition table wont change unless a reboot is done. After wiping vendor we flash the rom. if vendor is wiped, it wont even boot. All the device specific stuff will be in that partition, that's what project treble it
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] Anas Rahman:
Okay, my bad. I apologize
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] yoyovid:
My los 15.1 is working fine. Followed above steps and didn't wipe vendor as stated by other senior member. Still after flashing that gsi as system and rebooting fastboot mode opens.
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] M.A.P:
You didnt understand what I said. You shouldn't wipe vendor. Only should wipe it after repartition and thats what you did. you should flash the system image that is arm64 A only. If you tried a GSI and is mentioned that it is not tested on mtk or exynos then.. possibly it wont boot.
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] yoyovid:
YES MANY GSI ARE NOT BOOTING ON MTK. PHHUSSON 9.0 BOOTED FINE BUT IT IS HAVING BLUETOOTH AND WIFI ISSUE.LOS 15.1 IS WORKING AWSOME BUT HAVE MINOR NETWORK BUG(network disappears randomly and comes back after restart).BTW THNX TO DEVS FOR THIE WORK ON THIS DEVICE.
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] softmaster3:
first i'd like to thank the developer so much for his great work

I installed the rom and there is a notable improvement to battery life

but i'm facing some problems beside network issues other members stated

first is the charging.. turbo charging is gone and to use it i have to turn off the phone then connect charger or else charging takes too long ..is there a workaround?

second is the heat ...in the stock rom the only sensor available was the battery temperature sensor but now there is a cpu temperature sensor and it giving erratic readings ..most of the time its above 50 c and spikes for over 80 c

last thing i miss from the stock rom is color modes especially vivid mode ...is there a tool or replacement for that?
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] AzureCat:
Amazing work bro , your the only one who didn't abandon this device , gotta love you for that , just recently got this phone and I've seen that there is minor bugs in the stock Oreo of this Device when it comes to gaming , so I'm wondering how games like PUBG work , there is no lag in 7.1 Nougat :3
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] Anas Rahman:
Had a bad time playing PUBG on stock OREO, Nougat wasn't far off, but still better. However with custom ROMS PUBG now runs smooth at low settings without almost any lags
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] Spanster04:
Brother, we can never thank you enough for working so hard on this phone and giving us the best mods which the company wouldn't. Treble support is great, and I can't wait to check it out.

As some users have realised that there's a network bug with the rom, im sorry i can't test it right now, as network is my first priority. I will surely flash it once the bug has been removed. Thanks again, you really are a blessing for K8 note users.:)
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] M.A.P:
Thanks but what did you say LOL. The network bug is only for some people, that too was fixed the next day of the release. If you still face issue.. then simply select one sim to 3g or 2g while the other is in 4g. There is no dual 4g support even though the soc is capable of it. Thats why in settings you'll have lte option for both sims . Put one in 3g or 2g and reboot.
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] Spanster04:
So it's fixed then? Sorry didn't realise. Will flash it tomorrow and give feedback.:good:

Has anyone tried flashing GSI on this ROM?
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] softmaster3:
No answer ?

and i did upgrade to the latest build and still have network issues ..maybe worse than first build
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] Anas Rahman:
Yes, currently on Pixel Experience....but RR worked fine aswell.

---------- Post added at 12:30 PM ---------- Previous post was at 12:08 PM ----------

I don't have a network problem on the latest build. Yes, the mobile data gets disconnected sometimes but doesn't take more than 10 secs to get back.

As for the charging, don't think that turbocharge is possible in GSI. Maybe a custom kernel could add that. Personally, I have slow charging issue on RR but I switched to PE yesterday and feel improvement in charging speeds. though not any extreme changes.

No idea about CPU Temps...

I couldn't find a way to add presets like Vivid etc to display.. Been looking for it myself but I found an app called "Color Changer" which let's you boost saturation manually. The saturation feature is paid but the app offers 3day free trial to check it out.

EDIT : found a better app called "sa2ration" that's free to boost saturation
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] kk9999gada:
Pie or Oreo?

Can you share link to PE GSI?
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] Anas Rahman:
I'm on pie...

https://github.com/phhusson/treble_experimentations/wiki/Generic-System-Image-(GSI)-list

Here's a link to all GSIs
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] kk9999gada:
I was successfully able to flash and boot PE GSI but it kept throwing dialogue on every reboot saying something like "Internal Error Occurred with your device...... Contact Manufacturer" and also one app was force closing, don't know which app.

Also TWRP is unable to mount my /data partition. This is even before I flashed anything.

Eventually, I ended up with Recovery loop.

Nevemind, this isn't my primary device and is unusable even with stock rom because the phone switches off immediately after unplugging. It was just lying in the corner, so I just want to do something with it.

I have reverted back to Stock ROM using SP Flash Tool, also restored back IMEI, WiFi/Bluetooth MAC address. Everything is fine now.

Thank You for link.

Also thanks to the developer for making Custom ROM dream for this phone come true. Really appreciate all the efforts.
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] Anas Rahman:
If TWRP is unable to mount /data did you flashed encrypt disabler correctly and format data..As for the app that's crashing is probably the phone app (for me it was the phone app so I'm guessing) you probably didn't wipe data before flashing... You can see if removing your Google account helps next time

The internet error is nothing significant, just ignore it.
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] kk9999gada:
Do you mean I should flash Encrypt Disabler first then I'll be able to mount and wipe /data?
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] Anas Rahman:
That should do it imo

---------- Post added at 04:46 PM ---------- Previous post was at 04:45 PM ----------

That should do it imo.
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] kk9999gada:
Edit: I think it worked. GSI is up and running this time without any app crash. Wi-Fi works but Bluetooth doesn't.

Flashed Encrypt disabler and then reboot again to recovery then flashed repartition and again rebooted. This time i didn't got "cannot mount /data" and was able to wipe it too.

One more thing, should I flash Encrypt Disabler again after flashing GSI?
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] Anas Rahman:
If it booted and you can see your internal storage in TWRP it's fine, you don't need to..

I don't think Bluetooth works in any of the GSIs
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] M.A.P:
If using dual sim, set one of them to 2g or 3g manually in settings
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] M.A.P:
That is strange, I'm using my 5 GHz wifi and is working in all GSIs
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] kk9999gada:
There was some sort of misunderstanding. WiFi is working fine both the bands in your ROM. The problem is with GSI.

Edit: Bluetooth is working on phhusson's AOSP GSI.

For restoring IMEI, just follow this guide:

[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] kk9999gada:
[MENTION=7832837]M.A.P[/MENTION]

I just wanted to know if this is possible?

I was thinking of another way for going back to Stock ROM in a way, so that we don't lose IMEI, MAC Address & SN due to SP Flash Tool, by modifying the update-binary of repartition.zip to this:

umount -l /dev/block/mmcblk0p28
umount -l /dev/block/mmcblk0p33

sgdisk /dev/block/mmcblk0 --delete 28
sgdisk /dev/block/mmcblk0 --delete 33

sgdisk /dev/block/mmcblk0 --new=28:458752:14090239
sgdisk /dev/block/mmcblk0 --change-name=28:system

mke2fs -b 8192-T ext4 /dev/block/mmcblk0p28

Steps that we can perform for restoring stock rom:

Copy system.img & boot.img (optional: recovery.img - for installing OTAs) from fastboot firmware to SD Card.

Flash stock_repartition.zip

Reboot to Recovery

Wipe /system & /data

Now restore system.img, boot.img and recovery.img(if any)
[Lenovo K8 Note ROMs, Kernels, Recoveries, & Other ] M.A.P:
Well I updated the post yesterday, you can select firmware upgrade option and flash the stock rom and you wont loose imei and serial no
