[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
Actually all the right modems/baseband gets flashed automatically by flashing latest OOS, so flashing OOS 3.6.1 should have solved the problem already, maybe try again?

I hope you did the by [MENTION=2948558]Spannaa[/MENTION] recommended EFS backup (dd method by using terminal emulator) in his legendary OP2 firmware thread, there's a recommendation in post 2 I think to pull your unique and device specific EFS partition as early as possible, because if you mess this part up your phone will lose signal and therefore the function which defines it as a mobile phone, even TWRP backups of EFS weren't reliable in the past, hence the clean dd variant...
[OnePlus 2 Q&A, Help & Troubleshooting] pololovestreks:
I don't think I've done what is recommended.

What do I do now?

Also, could you post the link to the thread?

Also, could you post the link to the thread?
[OnePlus 2 Q&A, Help & Troubleshooting] Spannaa:
The EFS backup zip is in post #2 of this thread and, if you're completely stuck, there are links there for stock reset threads which may help.
[OnePlus 2 Q&A, Help & Troubleshooting] pololovestreks:
So I finally managed to restore it to OOS 3.0.2 with fastboot and have upgraded it to OOS 3.6.1 now.

Now when I try to flash a custom ROM like RR, it gets stuck on boot animation, any step that I am missing or any tutorial that I need to follow?
[OnePlus 2 Q&A, Help & Troubleshooting] Spannaa:
Normally, wiping system, data & both caches and then flashing the rom using the latest TWRP should work.
[OnePlus 2 Q&A, Help & Troubleshooting] pololovestreks:
Is there like a modified TWRP that I have to use, or encrypt/decrypt something or maybe flash magisk along with it?

I tried flashing the Nougat version of RR, it gets stuck on Boot animation too
[OnePlus 2 Q&A, Help & Troubleshooting] Spannaa:
It's been a long time since I had a OnePlus 2 but I don't think you need a modified TWRP and I don't think OOS is encrypted by default on this device.

If you were on stock OOS 3.6.1 with stock recovery, did you boot directly into TWRP after fastboot flashing it before booting system?

Have you tried asking in the RR thread?
[OnePlus 2 Q&A, Help & Troubleshooting] pololovestreks:
Should that make a difference?

I'll try asking

Do I have to unlock the bootloader again after flashing stock OOS 3.6.1
[OnePlus 2 Q&A, Help & Troubleshooting] Spannaa:
It makes a difference if you were on stock recovery with stock OOS.

If your bootloader was already unlocked and you didn't relock it, it should still be unlocked.
[OnePlus 2 Q&A, Help & Troubleshooting] pololovestreks:
So this is what I do

I am on stock OOS 3.6.1 and stock recovery

Enter fastboot

flash custom recovery

reboot into custom recovery

clean data/cache, flash RR & GApps

Gets stuck at boot animation

If I reboot into the system after flashing the custom recovery it replaces it with the stock recovery.
[OnePlus 2 Q&A, Help & Troubleshooting] Spannaa:
Don't reboot into system after fastboot flashing TWRP, boot directly into TWRP first, then it should stick and you can reboot into system.

You should then be able to reboot into TWRP and flash RR & GApps after wiping data & both caches.

I'd still ask in the RR thread though as it may have a special installation method.
[OnePlus 2 Q&A, Help & Troubleshooting] pololovestreks:
That is exactly how I am doing it, still gets stuck at the boot animation logo, that's why I wondered if I was doing anything wrong
[OnePlus 2 Q&A, Help & Troubleshooting] Spannaa:
If you're waiting 10 minutes or so after flashing the rom & GApps and it's still not booted then I don't know what's wrong.
[OnePlus 2 Q&A, Help & Troubleshooting] pololovestreks:
can't figure it out either, tried flashing Lineage and it's stuck on the boot animation too.

Any clue at all?
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
This command should give you info about the bootloader status, post the output. I was under the impression that the stock reset tool locks the bootloader, so you're in a factory state when you successfully ran it but I never needed to use it myself in my OP2 days....

fastboot oem device-info

Also try flashing Magisk 17.1 along with the custom ROM, maybe it's a kind of encryption issue that magisk can handle, there was a similar case already on this thread which was solved successfully but I can't remember if it was the exact same thing and what was done exactly, I'll check later when I have time to find it and report back when I have a clue or you can also check the thread via the search bar to find corresponding posts...
[OnePlus 2 Q&A, Help & Troubleshooting] Spannaa:
I was under the impression that [MENTION=9453669]pololovestreks[/MENTION] used my unofficial Oxygen OS 3.0.2 fastboot zip and then updated to OOS 3.6.1 so his bootloader shouldn't be locked but, as you said, fastboot oem device-info would clarify this.

I didn't think that OOS for the OP2 was encrypted by default?
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
Yeah, now as you said it I remember there's definitely no default encryption on OP2... I'm very sure about it, I would also be surprised if you weren't right about the reset tool but let's see the command line output :)
[OnePlus 2 Q&A, Help & Troubleshooting] pololovestreks:

[OnePlus 2 Q&A, Help & Troubleshooting] Spannaa:
When you restored to OOS 3.0.2 with the fastboot zip and then upgraded to OOS 3.6.1, was your EFS still corrupt?

Did both sim slots have an IMEI number? (Different IMEIs and neither of them 0)?

If so, then your EFS probably isn't corrupt.
[OnePlus 2 Q&A, Help & Troubleshooting] pololovestreks:
EFS isn't corrupt anymore.

Its just that OOS 3.6.1 and RR Oreo have vast differences, that's why I'm looking to shift

---------- Post added at 04:53 PM ---------- Previous post was at 04:39 PM ----------

I vaguely remember there being a modified twrp recovery file for some reason, maybe that would help.

Do you have a link to that?
[OnePlus 2 Q&A, Help & Troubleshooting] Spannaa:
IIRC, the modified TWRP was for switching between H2OS and OOS 2 so it'd be of no use here.

Have you asked about your issue in the RR thread?
[OnePlus 2 Q&A, Help & Troubleshooting] pololovestreks:
Yes, I have!

Haven't got any solution (yet)
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
Sure you flash correctly, you do the necessary wipes of system, data, cache and Dalvik/ART?

And you have a compatible version of TWRP for flashing? Did you check the custom ROM thread for a recommendation of TWRP?

The only modified TWRP I know for OP2 is hybrid twrp, used when different bootloaders (OOS vs. H2OS) made issues and normal TWRP wasn't able to handle this but this issues are long gone and hybrid TWRP is outdated...

[OnePlus 2 Q&A, Help & Troubleshooting] chewbaccadoggie:
Just updated my op2 to lineage os 16.0 (pie). Haven't used it too much to say much but here are some stuffs I've been noticing.

1) I was running pixel experience ( 9.0 ) before but it seem to had some issue with a few games so I switched to this. The first time I installed this it got stuck in a boot loop I restored my phone back to PE ( I had a backup ) but that too got stuck in a boot loop too. I wiped data, cache and internal data too. And it worked. Now I re-flashed Lineage os and gapps and everything its working perfectly fine but at some points I'm getting pixel notifications which I did on Pixel experience rom ( " continue setting up your pixel " etc ). Any comments ?

2) Whenever I try changing my display to dark mode from display settings my settings crash.

That's all for now.

PS: I'm using TWRP recovery. And I'm more or less a noob to this and know only most of the stuff due to YouTube research.

Thanks for reading :fingers-crossed:

PPS: Which will be the best kernel to get most performance out of my device ? I'm using stock kernel for as far as I know because I've not yet done anything to kernel.

edit: Never mind my following question, what I did to fix it is install the correct ROM recovery file.

Hi I am a first time noob, I just "unlocked" my phone, and now have root privilege, I have TWRP installed, however I can't seem to install a new ROM correctly.

I am trying to install this ROM from the XDA original development forum: ROM OFFICIAL LineageOS 17.1 for Oneplus2 | Android 10

And I use open_gapps-arm64-10.0-pico as gapps.

The installation is successful, however my phone does not seem able to boot into the the OS.

Restoration works fine, and I can use my old, oxygen install, so no major problem.

But what am I doing wrong?

---------- Post added at 11:28 AM ---------- Previous post was at 11:13 AM ----------

I had the same kind of issue, I booted into recovery, (hold volume down and power button) I then reinstalled the original OS with files from the OnePlus website.

And flashed the original boot loader.

I think it's because if a mismatch between OS and the bootloader, but I am noob myself, so take it with a grain of salt.
[OnePlus 2 Q&A, Help & Troubleshooting] BringBackJerseyShowah:
Really hoping this is the correct thread :)

I have a OP2 running LineageOS 17.1, latest stable release. Works great, love it. But ~August it developed a small quirky problem -- my apps that backup to the cloud when on wifi seem to think it's still only connected to the cell network, and won't backup. This is even when in the wifi connection's settings I set it as an 'unmetered' connection.

The two apps are Google Photos & Nextcloud client. Because of both apps having the same issue, I am presuming that this is an Android problem.

Has anyone else had this? Perhaps any suggestions? Any help is greatly appreciated.

TWRP fail to decrypt OPT

Ola,

This is a copy of my opening post from the Oneplus forums. It got lost amongst the million: "yaay, i got an invite", "look, my OPT is amazing!" threads.

This is a problem I encountered when trying to flash the Oxygen 2.1 through TWRP. I believe this is a 2.8.7.0 recompile by ydss.cn (googling maybe a chinese coder)

The phone is encrypted.

Restarting into TWRP recovery (sadly cannot paste external link android hostfile fid=24052804347797409) you're prompted to enter the decryption password (similar to when I'd boot the phone). Regardless of the user input, The following error message is recieved: E: unable to mount storage

I am able to access the phone if I reboot to the system normally.

This is eerily similar to the bug encountered with OPO and TWRP 2.8.6.0 which Dees-Troy kindly crushed and I wonder if this is the same Qualcomm hardware encryption problem just roaring its head again in OPT.

But if this a straight 2.8.7.0 recompile shouldn't this be resolved?

If this is also similar to the aforementioned OPO problem, I think one should still be able to flash OTAs either through ADB sideload or USB OTG (but I haven't tried either yet).

Anyone has similar problems?

As the compile is not offical I hesitate to post this in Github or email team win directly. (I'd love to pretend I can compile TWRP for oneplus2, but the chances of that are as slim as recieving an OPT invite )

Just reboot into safe mode and then reboot as normal. Should come back.

1. Power down the OnePlus

2. Hold the power down button until Android starts to boot up

3. As soon as Android starts booting up let go of the power button

4. Then immediately start holding both the Volume Up and Volume Down buttons

5. Continue holding both Volume buttons until it boots into the OS

6. You will see it's in Safemode

Once it fully boots up just reboot the phone as normal. No need to do anything else.

[OnePlus 2 Q&A, Help & Troubleshooting] OF_XDA:
Correct.

But I finally recovered the device. Here are the steps I followed:

1. Downloaded and unpacked the "full Oxygen OS 150805 restoration package" from http://xdaforums.com/oneplus-2/general/oneplus-solution-hard-bricked-device-t3183449.

2. Switched off the phone, connected it to PC and started Device Manager.

3. Pressed all three buttons simultaneously: Power, Vol+, Vol-.

4. The phone screen was still swithed off, but the device appeared in Device Manager as Unknown in "Ports" section.

5. Selected "Update driver" and pointed to QHSUSB_BULK directory. Windows installed "Qualcomm HS-USB QDLoader 9008" driver.

Note: For some reason it wasn't "Qualcomm HS-USB Diagnostics 9006" as it said in the instructions above.

6. After that I started A2001_14_A.03_150805\MSM8994DownloadTool.exe ans pressed Start button there. It seemed to me that nothing happened for several minutes, so I pressed Stop button and quit the tool.

7. But after that I finally could start the phone to stock Hydrogen Recovery mode!

8. In Recovery I selected "Update from USB", so Windows installed ADB driver.

9. Then I opened command prompt and issued "adb sideload OnePlus2Oxygen_14_OTA_008_all_1509191929.zip" command to update the phone with the latest firmware.

10. After the update process has been finished phone was able to start normally.

Hope this kind of "guide" will be useful for others :)
