Hello,

The latest version bricked my device to the point of showing as QUSB_BULK in device manager. I had to use the MSM download tool to recover from the "hard brick".

After recovering the device I resumed flashing this ROM. Now the device will not boot and goes to bootloader.

I think there might be something wrong?

EDIT: Flashed official 9.0.3 from here (https://xdaforums.com/oneplus-3t/development/oneplus-3t-android-pie-beta-t3924634) and booted ok. I then rebooted to recovery and flashed this rom version of 9.0.3 and it is working! Yay!

Thanks
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] sp0979:
R u saying, TheOne3Tos rom has bricked the device?
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] tim071286:
Other people have mentioned boot issue.

I clean flashed and it soft bricked as I said above.
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] cucumbersmell:
After dirty flashing, did you reboot to Recovery before rebooting to System?

Just curious as the instructions for dirty flashing on the Official ROM thread say:

"Reboot to TWRP (to retain recovery as TWRP)"

Thanks

---------- Post added at 03:27 PM ---------- Previous post was at 02:35 PM ----------

Dirty flashed from theOne3TOS 9.0.2 to theOne3TOS 9.0.3 with no issue. Was already encrypted. I did the following:

1. Made a TWRP backup. (Using Enhanced TWRP, but official will probably work just the same.)

2. Backed up everything important to a PC/external drive. (Cause I'm paranoid.)

3. Disabled all substratum overlays and xposed.

4. Wiped Dalvik and Cache.

5. Flashed theOne3TOS.9.0.3-PIE.Aroma.zip (Selected Magisk 19.3 in Aroma.)

6. Went back to TWRP after Aroma was finished.

7. Rebooted to Recovery to preserve TWRP. (May not be necessary, but was easy.)

8. Rebooted to System.

9. Success! Updated and kept data!
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] Spaqin:
Oh yeah, I missed that somehow.

I don't think I ever did that when dirty flashing this rom before, but I will keep that in mind for later releases.
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] cookwu:
Problem found. Here's what I did with encrypted 9.0.2 rom.

Flash the enhanced recovery image

Remove the OOS Native Call Recording Enabler Magisk module

Reboot to recovery and flash the 9.0.3 rom (Choose Magisk 19.3 as root)

Back to TWRP when finished

Reboot to TWRP

Reboot to System in TWRP and the reboot-to-recovery condition gone

This problem is mentioned from the thread.

Thanks for [MENTION=997979]Bradl79[/MENTION] 's work, this is really a perfect rom.

Also Magisk is unable to load the modules after a few reboots (this means no Viper, Xposed, etc). I tried installing them manually as the add-on wasn't working
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] smartpr1v4t3:
Thanks for your rom, i really like stock oos but i prefer to rebloat and have magisk in one installer.

9.02 was really buggy for me 9.0.3 is running smooth and without any problems at the moment

[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] undrwater:
Correct. "Circle" is there, but percentage location is not. I suppose that's Oreo and hasn't reached Pie just yet.

Thanks for the update.

Anybody else has the problem that the alarm clock isnt ringing?

It is working for me after deleting app data but only for some days.
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] Looki75:
I did experience a glitch with the alarm app.

I don't know if it is the same than you...

The alarm would fire but with no sound.

That was because I used my own mp3 as the alarm sound and somehow at one point the alarm lost the "access to storage" authorization.

It happened a second time and granting again the authorization (in settings/apps/etc...) solved the issue immediately...

I don't know what triggered the lost of this authorization...
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] smartpr1v4t3:
I use the default sound but will try this out thanks, maybe it helps.

Another question about Franco Kernel.

The Stock Kernel should work on our rom or?

Because when i search with the franco app i only find the kernel for custom one.

Thank you so much for the great support of the 3t. Ordered my 7pro today (yeah, i'm a nerd ... 64gb is not enough...and money ist just money). Hope there will be a 7t rom someday [MENTION=997979]Bradl79[/MENTION]

That is awesome, you are going to love it and thank you for all the support u provided me! I do have a rom but it's not near as complex due to aroma not being compatible, it's a magisk module based rom of the favorite debloating, apps and optimizations that I have on here. Again thank you!

[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] baconatorXVI:
Hi guys, it's been many years since I have been active on XDA. I have been googling trying to figure this out with no success. I have what appears to be extremely high cpu usage while idle, phone gets hot in pocket on the cpu area after sitting with screen off for like an hour. I updated from a 7.x android version to one of the recent 9.0.4 builds with a completely clean install and followed all instructions. To complicate matters apparently after android 8 you can no longer monitor the specific app CPU usage levels. So I don't know if I have some rogue app that doesn't play well with android 9(I am very minimalist with the amount of apps I keep on my phone) or if there's something wrong with the default kernel or the build I am running.

Have any of you dealt with problematic high CPU usage with any of the recent android pie builds? Battery usage has been high for the last few days since I installed the updates. Oh also the camera isn't working(black screen front and rear camera, settings accessible) but I haven't had the time to trouble shoot anything.

Edit: I just used titanium backup and froze all user apps besides a single monitoring app and there was no change to idle cpu frequency. Seems to always idle at 12XX mhz or greater.

Edit 2: I dunno what fixed this it's not high idling anymore. Maybe it was a reboot that fixed it. Who knows.
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] Looki75:
Obviously I don't know if that will apply to your situation, but: if you observed a high cpu usage shortly after the upgrade, it could be normal.

When you upgrade the ROM, many things are going on under the hood and cpu could get very busy for quite a bunch of time. Especially if you jump 2 major Android versions (from 7 to 9 in your case)...

Speculation now: maybe the system even waits for "user absent" to start its background tasks... which could explain high cpu usage "after 1h idling"...

I have trouble with this rom i can't boot in rom or twrp please help me
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] Looki75:
Well, tout need to give more details...

Your statement is so vague that the only answer would be:

1. Make sur you have the latest version of TWRP

2. Read carefully first post so that you don't miss any step

3. Start over the whole procedure as described in first post

Good luck
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] baba duy:

can i ask you i have trouble with thermal-engine i don't know how to fix i OC CPU and GPU and set max frequency CPU and GPU when it hot it drop to minimum help me
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] Looki75:
You can install a custom Kernel (for example Franco or ElementalX) and you will have the option to choose which thermal engine you want to use (either in the Kernel's app or Kernel adiutor)

But regardless of which you will use, the phone will get hot if you use it too much and then thermal throttling will happen.

You can switch off thermal engine, but in this case the phone will get hotter and hotter and suddenly simply shutdown itself when too hot...
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] baba duy:
where can i switch off thermal engine ? :confused::confused::confused:
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] Looki75:

mine works, what options did u choose and by brick do you mean bootloop? booting to recovery only? Booting back to fastboot? or Black screen only. We need more info instead of it bricked. Pretty much everything is magisk based so it won't give you a hard brick! If you flashed Dolby then u may want to delete it b/c that may not be PIE compatible.

[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] Bradl79:
Update Everyone... Enjoy

theOne3TOS - 9.0.5
[B][U]System[/U][/B]
-Updated Android security patch to 2019.8
-General bug fixes and improvements
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] Spaqin:
Huh.

I installed the 9.0.5 update w/ add-on, and at first stupidly went with dolby.

Now when I boot into the system, I am immediately greeted with "powering off" window and it reboots into recovery...

what do?

[edit1]

something's ****ed alright, I went back to 9.0.3 and got the same, safe mode, same ****, so I got a logcat from the boot process and what I found very concerning was this:

java.lang.RuntimeException: Unable to instantiate application com.android.phone.PhoneApp: java.lang.ClassNotFoundException: Didn't find class "com.android.phone.PhoneApp" on path: DexPathList[[zip file "/system/framework/org.apache.http.legacy.boot.jar", zip file "/system/priv-app/TeleService/TeleService.apk"],nativeLibraryDirectories=[/system/priv-app/TeleService/lib/arm64, /system/priv-app/TeleService/TeleService.apk!/lib/arm64-v8a, /system/lib64, /system/vendor/lib64, /system/lib64, /system/vendor/lib64]]

probably caused by:

Suppressed: java.io.IOException: Failed to open dex files from /system/priv-app/TeleService/TeleService.apk because: Failure to verify dex file '/system/priv-app/TeleService/TeleService.apk': Bad checksum (1d1d49ba, expected 8a8b49aa)

or more probable cause would be a segmentation fault:

08-16 09:36:31.025 687 687 F libc : Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x0 in tid 687 (mm-pp-dpps), pid 687 (mm-pp-dpps)

regardless, I have attached the full logcat.

[edit2]

Took me an hour or so. I didn't make a backup because I didn't think it would be a problematic upgrade, so I was determined to make it work without cleaning /data. It was pissing me off so much, I first removed segfaulting mm-pp-dpps, which did nothing (except for removing the segfault from the log).

Then I tried comparing the checksums of stuff in TeleService.apk, but I couldn't find a match with either checksum listed. Pissed off, removed the /system/priv-app/TeleService altogether. Same error.

one ``find -name TeleService.apk -maxdepth 20`` yielded a single result... /data/adb/modules/FingerprintBackHome/priv-app/TeleService/TeleService.apk. I removed that folder too, and guess what, it booted properly. SIM card was not detected, but I expected that.

One ROM reinstall later, I'm finally left with a fully working system.

I have no idea how did that apk appeared there, why it wasn't a copy of the one from the system. I seriously considered going Apple for a moment.

Seems it was a magisk module for fingerprint gestures that didn't work that kind of broke itself on upgrade for god forsaken reason. Did anyone have any luck with fingerprint sensor gestures anyway? I couldn't get them to work.
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] Looki75:
Try to uninstall the Magisk module(s) directly from recovery's terminal.

There is a specific recovery flashable zip for that.

(Sorry I can't tell you the name of this zip.... I don't have 3T with me right now since my daily driver is now 7 Pro...)

In my case, it solved all my non-booting issues...
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] Spaqin:
Thanks, I got it all sorted out myself.

Now I know it would've worked. I didn't think a non-working module (that I even forgot about) would stay dormant and cause a bootloop so far down the line.

I did a clean install of the latest open beta build and everything went smoothly and worked flawlessly except for phone calls. Everytime I receive a phone call, my phone vibrates but nothing pops up on the screen so I can't answer or decline the call. Also, If I call someone from my contacts the phone will ring and they can pick up the call but nothing pops up on my screen and I'm just stuck on my home screen. The call, however, works but I can't put it on speaker or end the call.

Any help would be appreciated as I'm a bit unfamiliar with these kinds of issues and troubleshooting them.

Just to let you know....

I tried to put together my "version" of TheOne3T by copying files from the official OnePlus ROM bundle into the TheOne3T zip file.

This way of doing things... worked perfectly for me in the past... (waiting for your build)...

Maybe I did something wrong, but this time it didn't work at all... I mean really...

After flash and reboot, the airplane icon was there... although phone was not in airplane mode before booting into TWRP for installing...

And as soon as lockscreen was showing the phone was writing "switching off" and after about 5sec booted back into TWRP...

I tried again and again - no luck...

Maybe something special with the updated modem...

Anyway, I finally flashed directly the OnePlus ROM bundle from TWRP... and that resulted in corrupted DATA partition... so full reset, etc... :silly:

Not a big deal since my daily driver is OnePlus 7 Pro now... but I thought I would let you know...

Waiting for your build! :)
