Not able to get volte, tried clean flashing OOS 3.5.6 as well but no luck. Volte doesn't seem to work. Anyone who experienced this and has a possible fix? Volte seemed to suddenly disappear and never reappeared. Tried using different Volte sim as well but no luck. Help would be really appreciated
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
So it's 100% sure volte is enabled by your provider?

You have volte capable sim in slot1?

Enabled volte from settings (wireless & network, sim card, enhanced lte)?

Did it ever work for you?
[OnePlus 2 Q&A, Help & Troubleshooting] mohamm3edadam:
Yeah I'm 100% sure, it always used to work for me when I was on OOS 3.5.6 and RR but when I tried going back to OOS I accidentally flashed OOS 3.1 and later when I went back to 3.5.6 it worked for a 2 days and later it suddenly disappeared. I tried clean flashing 3.5.6 and even RR but still no luck.

PS- I'm using Jio sim and I even tried changing the sim, still couldn't make it work
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
Here are all modems as flashable zips, make sure you're really on 3.5.6 and have volte sim in slot1, check again in network settings if volte is available..

https://xdaforums.com/oneplus-2/gen...cial-oxygen-os-roms-ota-t3209863/post70320274

But I cannot tell you more than that, I actually don't use volte, it's meaningless where I come from..

Good luck
[OnePlus 2 Q&A, Help & Troubleshooting] mohamm3edadam:
Thanks a lot, can you just do me a favour my checking yours and my baseband version if you're on 3.5.6? Cause I did check with my friend and it was the same
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
Sorry but I'm on 3.1

But if you flash again the linked 3.5.6 package you should be good to go..
[OnePlus 2 Q&A, Help & Troubleshooting] achuth20:
I have a twrp backup (with every partition checked) from when i was on oos 3.1.0 and now I'm on oos 3.5.6. If i restore the backup it should get me back on oos 3.1.0 with the old modem right?

I only ask because i read on spanna's thread that although twrp says it backs up the EFS it really doesn't.

Thanks in advance :p
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
I'm not sure, I think its not going to change the baseband (modem) if you restore your backup only the oxygen version will change but I don't use OOS so I haven't tried myself, I also wouldn't recommend to backup EFS with twrp or restore it, use either hybrid for that or the EFS backup zip i linked a few posts earlier..

If you want to switch back to 3.1 modem use the zips from link above or flash the full signed zip from Spannaa if you want back to full OOS 3.1
[OnePlus 2 Q&A, Help & Troubleshooting] Spannaa:
[MENTION=7125933]Sam Nakamura[/MENTION] - as well as the full, signed flashable zips in post #1, there are firmware zips & EFS backup zips in post #2 of my mirrors thread ;)
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
Thanks for the hint Bro :highfive:, I totally missed this and was only aware of a user (FPSUsername) created firmware zip package..

That simplifies support issues
[OnePlus 2 Q&A, Help & Troubleshooting] achuth20:
Thank you so much for such a quick reply

Sorry to bother you again but if I'm getting this right if I flash the zips provided in the link , I'll be on oos 3.5.6 but with the old modem?
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
Maybe, I never tried it :)

The modem (firmware) zips are actually for custom rom support, for example you use lineageOS and can quickly switch between 3.1 firmware (modem) and 3.5.6, when it comes to using oxygen I would not use 3.5.6 on 3.1 modem (if even possible), just use the full signed flashable zips from official mirror here

What's the general consensus on the difference between dirty flash and clean flash?

I find different answers almost everywhere I look.
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
A clean flash is only done when you wipe everything except internal storage (i.e. System, Data, Cache, Dalvik/ART Cache) before flashing a ROM, albeit everything else is dirty flashed...

Edit:

Important is especially to wipe the Data partition for a clean flash as System gets usually wiped anyways by the installer script when flashing a ROM and Cache, Dalvik/ART Cache gets suggested to you after every successful flash in twrp, remember the two options if twrp is done, wipe dalvik & cache or reboot system..

Is there a way to manually update security level on a custom rom? I'm running a cm13 build.
[OnePlus 2 Q&A, Help & Troubleshooting] Spannaa:

[OnePlus 2 Q&A, Help & Troubleshooting] ThePeerlessFennecFox:
Install Update by dirty flashing

Good morning!

A while ago I installed the unofficial lineage os (https://xdaforums.com/oneplus-2/development/6-0-x-cyanogenmod-13-oneplus-2-t3292436) on my OnePlus 2. Now I would like to update the ROM to the newest version. The problem is, I encrypted my storage with the android encryption option. OTA doesnt seem to work (tells me "no connection" all the time) and the Hybrid Recovery gives me no option whatsoever to mount my encrypted storage. So when I wanted to wipe dalvik and cache to dirty-flash the update, it just failed and told me it could not mount the data partition.

What can I do? Install a new recovery? If yes, which one?

With kind regards

Fennec

Edit: while scrolling through my XDA app, I just realized that I seem to have asked a similar question about a month ago in this very thread O.o . I can't quite remember that I did that, but my memory is acting a little weird right now and I posted a fennec picture. So it was me, propably. Apparently I managed to use sideload or something ... no idea really. I'll google a little and try to figure out how to do that. I should really start to write things down before they go :/
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
This encryption caused lots of issues for quite some people.. Anyways, the most up-to-date custom recovery is twrp 3.1 see here:

https://eu.dl.twrp.me/oneplus2/

You can flash the image file from inside your recovery, choose install, image, recovery, swipe to flash and reboot to recovery...

If it still won't work you'll probably need to do a factory reset to get rid of the encryption and clean flash
[OnePlus 2 Q&A, Help & Troubleshooting] ThePeerlessFennecFox:
Thank you for your fast response.

I can't access my download folder over the recovery, since it's encrypted. I click on "install" and Hybrid Recovery shows me some empty folders. I tried to copy the img file to "system", but it tells me its read only. Trying sideload to install the img didn't work either. "access denied".

Edit: I managed to copy the image file to the root folder via root explorer. I can see the file when I click on "advanced" and "file manager" in hybrid recovery. However, when I click on "install" all the folders appear to be empty. Not sure if it just shows .zip files. There are no settings to change that.
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
It shows only zips by default, there is a option to change to image files, normally a button in the low right region, it's been quite a while since I used hybrid so excuse my faded memory.. But it's somewhere, it's a basic function
[OnePlus 2 Q&A, Help & Troubleshooting] ThePeerlessFennecFox:
Yeah, I know, I see the button right there. Thats the thing. Nothing happens if I press it, besides from the vibration that tells me it accepted my input. God, for once in my life I would like android to just work without obscure errors that take hours and hours of googling to fix.
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
If i was you, I'd backup important stuff as good as possible and would wipe everything except internal storage and clean flash the whole thing.. You can't update (dirty flash) to officially lineageOS anyways as the builds of official LineageOs are singed with a special key, you can only flash officials on officials, no switch from or to unofficial is possible.. Exept you bypass this with the very first "experimental" build, this one was made for switching from unofficial to official..

If you haven't updated for a while a clean flash is mandatory as things quickly change and you'll likely have issues if you dirty flash with a huge gap in between..

Encryption is always tricky, especially on some unofficial custom roms, even OEMs have difficulties with this from time to time..

There's one last chance I have in mind, it's possible to flash the recovery out of your running system by using flashify or rashr, as long as you have root, you could download those apps from Playstore..
[OnePlus 2 Q&A, Help & Troubleshooting] ThePeerlessFennecFox:
BÄM!

Flashify worked like a charm. Installed twrp without problems, booted into recovery, decrypted, installed the newest version of the unofficial LineageOs, rebooted successfully. Done.

:) That was a really good idea. Thank you very much!
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:

[OnePlus 2 Q&A, Help & Troubleshooting] ThePeerlessFennecFox:
Hey Sam,

Sorry, I was so happy that it finally worked that I ran off excitedly without checking if there were any questions. Ich gelobe Besserung.

Yeah, it's still encrypted. With "decrypted" I meant that the new recovery manages to properly mount the encrypted partitions (by asking me to input my encryption password).

No data, no apps, no settings were lost. I just got the newest lineage version (and boot screen yay!).

It's still telling me that it has "no connection", when I try to search for lineage updates over the android settings, but I can easily live with that. As long as manual updates every few weeks work.

Cheers,

Fennec

Hey friends!

I was curious if there is any custom rom that provides similar interface to lock apps as the one in the stock OOS?
[OnePlus 2 Q&A, Help & Troubleshooting] MZO:
I heard Unofficial RR just got that feature. Try it out ;)
[OnePlus 2 Q&A, Help & Troubleshooting] amitgudwill:
What are CAF roms? How are they different from the Aosp ones? Is the stock OOS rom based on aosp? Is there any aosp rom with similar app locking interface as that of the stock OOS??

Lastly, can anyone suggest some good aosp roms?
[OnePlus 2 Q&A, Help & Troubleshooting] MZO:
AOSP is the code by Google for Android. Qualcomm SoCs that aren't under Google don't work with AOSP code, Qualcomm releases their code in a website called CodeAurora Forums a.k.a CAF. So basically we don't have AOSP since we have a Qualcomm device. We have CAF only.

To your previous question: Use RR unofficial

[OnePlus 2 Q&A, Help & Troubleshooting] John Abraham:
I was talking about unofficial Resurrection Remix rom. They discourage noob questions in the development sections.

?
[OnePlus 2 Q&A, Help & Troubleshooting] utkarsh102:
1. RR has more customisations.

2. RR is based on Lineage. So basically you are using lineage with more modifications.

3. Yes, OMS is supported. As long as OMS is supported, the performance will be satisfactory.

4. Clean install. Its a different rom. Dirty flashes only for same roms.
[OnePlus 2 Q&A, Help & Troubleshooting] John Abraham:
Thanks..finally someone heartily attended a noob. I am flashing the unofficial RR.
[OnePlus 2 Q&A, Help & Troubleshooting] utkarsh102:
Good luck. Only one bug every lineage based rom has is network drops. If you get any, switch to an aosp based rom.
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
See, you found the perfect place to ask this kind of questions, please don't take it personal, it's just not suitable to ask those questions in the development section of a thread, it's not a place to get consultation which rom to flash, or to ask anything found with a simple Google search (i.e. lineageOS vs Resurrection Remix) and so on...

Thank you! Being an ex Iphone user I had little knowledge regarding development and I am amazed to see such great community over here.

btw I flashed the unofficial rr rom on my oneplus 2 and default pixel launcher crashes everytime I try to drag a icon to homescreen. any way out? is it possible to use Oneplus launcher v2 on this rom?
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
That's a limitation of the pixel launcher, as far as I know and there might be a trick from what I read but I don't remember, likely Google shows some results or you go to the RR development thread, there's a search bar to search the thread, search for something like pixel launcher..

I can absolutely recommend you the in my opinion best launcher Nova (PRIME), after years of usage it's still great developed, regular updates, heavily customizable, in fact it can imitate the look of the pixel launcher and overall problem-free... But there are plenty alternatives in store :)

Will you please explain it .i just can't seem to understand it fully.

As said here"You could, for instance, group all your social media under a single application group. Then you would be able to change the notification style/volume/tone of all of them at once. "

But the profile change the system sound so for all app it would be same thus there would not be any difference in sound of social media with respect to any other app.

???

Really i just can't understand it.
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
I think grouping them kind of excludes the chosen apps form the profile, like you group all social media and give them an LED color & certain ringtone and for the rest applies the settings from profile..

Hi guys, I am looking for the best ROM that has a possibility of taking photos in RAW, with good battery life. Doesn't matter anything else, can be whatever :)

Also, I have heard that if you rollback a few official ROMs, that that is a fix for random reboot on 7.? ROMs, is it true?

Thanks
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
HalogenOS, ValidusOS and unofficial RR have RAW (HAL3) implemented, you'll find them in the oneplus2 device specific forum in android development section, there are likely more, just check the changelog and first post of a Rom thread to see about HAL3 (RAW) or use the search function inside a thread to find this information..

Battery life is a complex topic, it heavily depends on your usage pattern and setup, there are plenty of guides on xda to learn about battery life, it takes some experience too, it's about how you manage your system, there is no rom which does this for you completely, so I can't recommend you a most battery friendly Rom as it's more important to carefully manage them, this way I personally get a SOT between 5 and 7 hours on all I ever have tried...
[OnePlus 2 Q&A, Help & Troubleshooting] S1611:
Can anyone please point me to a ROM with min./no network drops? Ive flashed (clean install) numerous 7.1 ROMs like, Carbon, Halogen, Xenon, DU, AOSCP etc. all of them has network drop issues even though most of them are AOSP/CAF based, which lead to horrible standby time. Each time I flashed pico Gapps from Opengapps which does not replace android contacts with Google contacts and I don't have Hike installed hence there should be no network issue but the only ROM which doesn't have this issue is OxygenOS 3.5.8 that I flashed before all 7.1 ROMs. So is this really a ROM problem and I'm doing something wrong at my end?

PS: I live in India and use Jio Volte as primary SIM.

Edit: Searched and found posts like these, that was in March, does it still holds true in June?
[OnePlus 2 Q&A, Help & Troubleshooting] darkbeast13:
I am currently using RR unofficial .flashed the pico from gapps.

No network drop till now (without hike , Google dialer, contacts and message)

Just to be sure flash the one plus firmware first and then flash the ROM.
[OnePlus 2 Q&A, Help & Troubleshooting] S1611:
Oneplus 3.5.8 firmware? Why? I ask because I had OOS 3.5.8 before 7.1 ROMs. Should I flash the firmware>ROM>Gapps (in that order) again?
[OnePlus 2 Q&A, Help & Troubleshooting] darkbeast13:
Yup thats the order . flash pico gapps only

Why firmware i can't recall the reason but you have to do it for the drivers of the modem for volte support.
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
Firmware needs to be flashed only once, if you did that already it's fine, no need to do it again but it wouldn't harm either. If you made sure you avoided the known apps causing network drops and still get this issue it's likely provider related, I'm not from India nor do I use Jio and I don't have drops at all, also the developer of RR official wrote some days ago that the Jio network is currently unstable and likely responsible for this..

By the way, on the download page of open gapps there's a link next to each individual package where you can read a description of what each package contains and replaces, pico is fine unless you want to use Google Assistant, then you'll need the nano package but as said, you can read it up yourself..

Hi all,

I had a OP1 and was really happy. I then moved to the OP2 and am very disappointed.

I have had to format it and request technical support more than 4 times in less then two years and now, with the last update, the same.

Phone is really slow and non responsive. Charging takes forever and last nothing. It crashes all the time.

In your honest opinion what should I do? Besides buying a new phone. Should I root it and change the rom? And if yes for what?

Please please please help!
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
There's not much to help, it's your decision, do you know what it means to flash a custom rom, unlock bootloader, flash a custom recovery, do proper backups? Using custom software has many benefits, it will make your phone better, charge faster and safer with the latest security patches BUT the downside is that there is a danger of breaking the phone partially or even completely, this won't happen if you be careful, do necessary backups (i.e. efs) and are willing to read and learn (Google is your friend!), to experiment and to find solutions, there're efforts you have to make, it does not come for free but you'll be rewarded with a unique system, tailor-made for you, fast & stable for the most part - with plenty of opportunities...

Understand that to be my personal opinion, different people may see it differently, of course :)
[OnePlus 2 Q&A, Help & Troubleshooting] bramirez37:
Hi, thanks for your fast and nice reply.

Have rooted more then one phone before and feel very comfortable with it. The problem is I am not a big fan of customization. I prefer performance and simplicity and never found a Rom I really though it was better then the default one.
