OP2 kernel problems, considering H2OS?

Hi all, I am new here. I was referred by a friend who knows more about this than I do. I think I understand how to get fastboot and TWRP, so that is taken care of already. Now the problem with my OP2 running OxygenOS latest version, everything stock, is that it freezes up after unlocking, and the whole phone is just terribly throttled at this slow speed for a long time. All inputs are extremely delayed, and touchscreen is nearly unusable after the lag begins. There are so far two temporary fixes I found: 1) reboot phone 2)wait it out/keep unlocking until it doesn't lag. I also have been unable to make a copy of my internal storage via USB, as it gives unspecified error during copying. And lastly, the screen dims on its own sometimes at random while anything related to auto-brightness should be off. Fortunately, I was able to make a hard copy of my internal storage thru some wifi file manager apps. Now my friend pointed out that my phone's issues could be related to a bad kernel. To remedy this, he told me it would be good to flash a new kernel onto my phone. I considered changing roms to CM, but apparently a lot of functionality is lost when doing this. He told me that I could retain Oxygen OS while flashing a new kernel, but I am not sure how to do this. I came across a post in the android dev section regarding hydrogen os, and I read that it performs better than Oxygen OS, but has minor issues of its own. I am interested in flashing this rom/kernel (I am not sure which is which). Here is the link in that section of the forum I found http://forum.xda-developers.com/oneplus-2/development/rom-h2os-hydrogen-os-ota-clean-stable-t3195636. I see it says that it is working on Indian OP2, and running stock rom and stock kernel. Does this mean that my north american OP2 won't be able to get this rom? Also if it is the stock kernel, does that mean it is the same kernel as the one currently installed on my phone? Anyways, if anyone knows about my phone's problems, or has a way to fix it let me hear it please. Thank you!

I had the same issue with O2. I changed kernels and the problems persisted. A also word the device and started from scratch through fastboot and the issues persisted. I ended up on hydrogen and I've never looked back. There is a flashable zip in that thread for the newest full version .11. Follow the steps wipe everything besides internal storage, flash the full v11 zip and boot the phone. After this reboot to recovery (power and volume down). Flash the gapps and super su zip if you want root. After this you should be able to add your Google account and be good to go. One thing I did was remove all Chinese apps and the stock launcher. I use trebuchet launcher from cm 12.1. Phone runs incredibly smooth now. I recently started running AK kernel as well. The oxygen version works with hydrogen. I have been averaging between 5 and 7 hours of SOT for battery with up to 8 if I'm just watching videos. Hope this helps. The ROM is a little simpler and the notifications settings are different. But you can set apps to have priority notifications and they function similar to oxygens notifications at that point. Everything is in the thread if you have any questions I'll try to help you.

Big problems after update for Android 7

Hello,
Yesterday i receive the notification for update for android nougat in my phone. The update ends without any problem but right now with this new firmware I have 3 BIG problems:
Back camera don't work > The camera apps open the front camera and i don't have the button to switch for the other camera.
Flash don't work > Flashlight app only controls the screen but do nothing to the flash.
Laser: The app for measure with the laser don´t open.
I already have done a factory reset without any success.
I already enter in safe mode without success.
I already clear all the cache without success.
Any ideas?
Are someone with the same problem?
Thanks!

Hi I updated my Zenfon 3 to Android 7 two wks ago after receive the msg from Asus. After reading your posting, I try all the problems mentioned in your article but it don't exist (maybe I'm lucky), in fact some of the pre exist (problem come with my purchase) problem such as the ear-phone connection problem has resolved. I have yet to find any major bugs in my Zenfon 3 yet. Overall I'm happy with the update.

Try reinstalling the ota. Flash via bootloader. Get the update file via asus site

I have done that but without success

I haven't experienced any issues. I factory reset right after updating though - you may want to give that a try.

If that is the case it may already be a phone issue. Flashing a device will do a clean install of the software. So any software issues should be resolved.
I suggest trying downgrading to the very first os in the asus site. Make sure you're using the same version though

Bootloop and radio issues

Hey there,
Ever since flashing a new rom I've been experiencing a few issues. First, my phone refuses to boot to system, I've had to go through the bootloader to get it started every time.
Second it would appear that my radio is off as the phone won't connect to the network and thinks its in aeroplane mode. I haven't been able to get it working yet.
The Rom I flashed was the nougat update. , I've tried several others since as well as restoring through twrp. No dice, but I'm currently on lineage 15,1
I've yet to find a solution to either of these issues in a week of searching so I'm looking for any sort of guidance.
Thanks in advance

You should return to a pure stock configuration (including recovery) and start over, preferably using RDS Lite. It won't be easy as there are no giudes written explicitly for the G4P. You will have to derive the procedure by reviewing other threads.
A less comprehensive approach is detailed in the following thread but it may not solve your radio issue.
https://forum.xda-developers.com/g4-play/how-to/guide-return-to-stock-firmware-recovery-t3551797
As for not booting to system that's likely due to a procedural error when twrp was first flashed. Check the TWRP threads for corrective action.

Screen problem

Hi everyone,
To flash the last rom (nightly ) of LineageOS ( in Oreo,from the 2 february), i had to put the firmware 5.1.7. After flash this firmware i was able to flash the ROM but it makes my phone extremely slow and with screen issues (i can still use the tactile but the screen doesnt follow).
I restored but the problem stills then i put le last stable ROM from Oneplus on android pie (9.0.3). It is a bit better (still really slow) and after a moment i get now like a white noise (same as on TV but with color moreover) by wink ( was more and more often on Google Maps), I had to reboot cause i couldnt use more my phone.
Thanks you in advance !
Ps : I've got TWRP from siankatabg and i'm not rooted , if you want me to send log tell me how pls.

Up :good:

When you were flashing did you used this instructions?
https://forum.xda-developers.com/oneplus-5/how-to/official-oxygenos-4-5-2-7-1-1-ota-t3627003
Flash codework's TWRP for Pie. After that reboot into recovery, wipe everything down and use clean flash instructions for your OTA. It should be able to fix any issue you were having. If not let me know.

Yes i followed the clean flash way (it didn't resolve my issue) but my issue occured before i flash pie, when i flashed lineageOS 15.1 with the firmware 5.1.7 required (which i flashed too). A restoration didnt change that issue.
I tried with the TWRP from codework but it doesnt recognise my internal stockage.
Thanks of your time.

Hi, try wiping everything down with the new TWRP, after that reboot into recovery once more. Install last normal working OOS to see if that helps you. If not maybe it is hardware issue? Let me know once you wiped and installed the last working OOS on it.
I have installed multiple roms and firmware updates on my device with codework's TWRP and never had big issue like this. In my opinion best option for you to trace your steps back to the last working version of your os and try learning what might have gone wrong.

My issues seem gone since few weeks with the last OTA (it very rarely happens now). I don't know what caused that even if i use my backup.
Thanks for your support !

Mi a1 touch issues

Hi,
I was on stock Pie firmware on mi a1. I tried to install twrp recovery in my device and somehow messed it up while flashing stock roms and all those things. Now my touch is not working properly. I can flash stock pie rom via fastboot method, but cannot go through setup process because my touch is a bizzare. I then tried to flash stock oreo and nougat firmwares and stuck in bootloop. I'm even tried booting into TWRP to see if anything would help, but the touch issue seems to affect twrp as well. Please help me out with this.
Thanks.

Do you fixed your problem? I don't know what happened but after I flashed the stock ROM the touch screen is useless. I already flashed everything in miflash and the screen is still broken... I don't know what to do, help pls

Hi!
I already fix a similar problem on my phone.
After a screen replacement, I had a touch-screen issue which was detecting the touches, but at a pseudo-random position.
The solution that worked for me was to flash the first stock nougat image released (September 2017 ), and then to upgrade to pie using the classical way through OTAs.
But you have to be very careful while doing this as you will encounter some kind of weird issues if you do this the wrong way, like lost IMEIs and some others that I don't remember.
You'll find some tutorial on how to downgrade from Pie to Oreo and then I don't remember well but I think you will be able to flash directly android one 7.1.2.
I hope this will solve your touchscreen issue (let me know if that worked for you or if you have any other problem occurring)
