[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
Thanks for your detailed answer, that's really interesting and would explain why the unlock command failed in this case, even when he had ADB on another windows machine running, probably the person who sold the device re-locked it before selling, without returning it to stock before, now it's stuck with a locked bootloader and some outdated software that won't even boot, the Qualcomm Recovery Package seems really to be the best (last) option here...

Doesn't it boot because of the custom software in combination with a locked bootloader?
[OnePlus 2 Q&A, Help & Troubleshooting] conqueror_25:
Honestly, I feel a bit frustrated on what happened to me here. I'm very careful on doing stuff like this on my device because I know only 1 mistake can turn your phone into a expensive paperweight. Been unlocking bootloader, flashing custom roms etc. since HTC One X days. The owner just mentioned to me that the phone is already rooted nothing else..

And it's my first time to use Oneplus smartphone and I'm really excited until this thing happened. Haha. ?

Luckily I still got my M9. I plan to pass this to my girlfriend once I fix my Oneplus 2.

Can't thank you enough guys for helping me out.

Cheers.
[OnePlus 2 Q&A, Help & Troubleshooting] Spannaa:
There are loads of possibilities...

Wrong SuperSU zip flashed, incompatible data, corrupt system files etc.

In this case though, as [MENTION=1988089]conqueror_25[/MENTION] can't get into recovery and wipe data, flash the correct SuperSU zip or flash a rom zip, the Qualcomm Recovery Package would seem to be the only option.

On the bright side, he'll have a completely clean device to start messing with!
[OnePlus 2 Q&A, Help & Troubleshooting] conqueror_25:
Hahaha. I'll look on the bright side of this mess then. Haha! Thanks man! If I can't fix it myself I will send it to a mobile phone shop as my last resort.

But how about the battery? Will it become drained and won't be able to power on to fix again.?
[OnePlus 2 Q&A, Help & Troubleshooting] Spannaa:
Just plug it in to the charger - it should still charge.
[OnePlus 2 Q&A, Help & Troubleshooting] conqueror_25:
Hey guys. You still there? Found a way to sideload a signed. Zip file to my device. It's through CM Recovery - Apply Update - Apply via ADB - then CMD command adb sideload zip file.

But I'm having error.. It's not finishing the transfer.

Please see photo. Thank you!
[OnePlus 2 Q&A, Help & Troubleshooting] Spannaa:
TWRP has an option to disable signature verification but I don't remember if cm recovery has this option - if it does, give it a try.
[OnePlus 2 Q&A, Help & Troubleshooting] conqueror_25:
I can't find also inside CM Recovery the option to disable signature verification. What's your best advice for me to do now since I can sideload a file now.

I mean which alternative zip file can I sideload to now?

A firmware zip from the link around 43mb size? Would it help if I sideload that?

---------- Post added at 05:29 PM ---------- Previous post was at 05:03 PM ----------

Or... If there's any zip file that can bypass signature verification and will flash successfully through sideload on my device.

Thank you.
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
As Spannaa mentioned and linked, the Qualcomm Reset Tool / procedure is the way to go, that's basically the same what customer service would perform, it returns your phone to a factory state with fully working OOS and recovery, that's the best solution, read the guide and make sure you understand what you are doing, if not ask where the guide was posted or here, but in this weird situation you're out of choices, IMHO..

Also you might be able to find a proper signed zip form cyanogenmod but I doubt it would flash because of the locked bootloader, that's why I think reseting it properly is the best choice, maybe even the only..

And another idea, you know about "fastboot boot twrp.img", this way the recovery will be loaded temporarily to the RAM and is temporarily accessible for you till you reboot or switch it off... But again, your locked bootloader makes me doubt if you could ever make use of a accessible twrp, maybe by switching off signature verification and flashing a rom but this way all could get worse too :) also in oneplus2 android development forum someone created a AIM rom build which is allegedly specifically flashable on locked bootloaders, rather risky of course as you can't even perform the proper EFS backups and therefore would depend on it working the first try... Hmm, again to solution mentioned several times, Qualcomm Reset Tool ☺️
[OnePlus 2 Q&A, Help & Troubleshooting] conqueror_25:
I'm really hoping everything will be alright after flashing this magic..

Thanks for your patience to me [MENTION=7125933]Sam Nakamura[/MENTION] and [MENTION=2948558]Spannaa[/MENTION].

More power to you both! ?
[OnePlus 2 Q&A, Help & Troubleshooting] conqueror_25:
Lo and behold my Oneplus 2 is alive again! Haha. Can't thank you enough guys for helping me and giving me the best advice possible.

I'm starting from scratch again. Unlock bootloader, flash recovery and install custom roms and kernel.

Hopefully I'll get it right this time. By the way, do you still recommend to do the 3rd steps - Tamper Options. My device is not covered by warranty anymore.

In the first boot I received a notification for latest OTA update. I guess I'll update it's stock Rom first to get the latest firmware for my device..

Thank you very much!

Cheers. ?
[OnePlus 2 Q&A, Help & Troubleshooting] Spannaa:
Glad you've finally got it all sorted out - it took a while but I'm sure you've learnt a lot :good:

I wouldn't bother re-setting the tamper bit ;)
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
Congratz :good: success

First update to 3.5.8 before you begin the journey, also I recommend you to visit Spannaa's firmware thread (link in my signature), there you find EFS backup scripts and lots of useful stuff..

The device is up and running again, I wouldn't reset the temper flag, it's just to make "fastboot oem device-info" saying "tampered devices: true" to "false", it's not worth any efforts to set it as tampered false if you going to trigger it the next step again by unlocking the bootloader, flashing a custom recovery, rom, kernel, etc.

Only sense it would make is with selling the device or RMA /customer service..
[OnePlus 2 Q&A, Help & Troubleshooting] conqueror_25:
Hahaha.. Yes yes. Noted that Sir! See you both at Android Development Thread! ?

You guys rock! ?
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
Well, no I don't have network drops (anymore), it's unfortunately a common issue with lineageOS and roms based on it for the OP2 that these network drops are produced by certain apps, Google Contacts infamously known to cause signal drops but also Hike, some say even Google Dailer..

Only solution is to avoid these apps by using a small Gapps package like open Gapps Nano, Pico Beans Gapps mini, the bigger Gapps packages will replace the well working stock Contacts App with the malfunctioning Google alternative (visit opengapps.org for a description what each package contains), so there's definitely a workaround by avoiding the known causes...
[OnePlus 2 Q&A, Help & Troubleshooting] vaibhavjoshi:

[MENTION=7125933]Sam Nakamura[/MENTION] Wasn't sure what would be the right thread to ask this, so I figured I could put it here. I'm currently on RR and am looking to try out AICP. Just wanted to get some feedback on someone who's used both. Not looking for a "is one better than the other", but more on the lines of how they differ from each other. I'm very happy with official RR, but since it lost its maintainer, I'm contemplating whether to switch back to RR unofficial or try out AICP.
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
Well, I love them both, my 2 absolut all time favs :)

RR unofficial has more features implemented but is also more experimental, AICP is pretty much straight pulled from sources and very stable with updates scheduled every Friday, less features than RR unofficial but still more than every other project...

It depends on taste really, I'd suggest you to take your time and check them both, I think you'd really miss something when leaving one out..
[OnePlus 2 Q&A, Help & Troubleshooting] Aahan:
Thanks for the feedback. Will clean flash the latest AICP build and see how it goes. Thanks!
[OnePlus 2 Q&A, Help & Troubleshooting] Lump91:
Hey guys,

First: i have read a lot here and in other threads.

I´m having problems with signal drops. But that´s not the main problem.

I´m on Congstar. Congstar is a subsidiary of Telekom /T-mobile in germany.

The network drops gone by preventing dialer and contacts, hike and so an.

But when i go to Settings, SIM, mobile telephone operators, i can't select neither congstar nor t.mobile. Automatical select work's, but then i do only have Edge.

Certainly LTE doesn't work.

I'm on the newest LOS with a clean flash. Does it help, to flash another modem from stock oxygen? Like 3.5.9?

And does it help, to flash the newest stock oxygen and after that a rom like LOS or RR? And if yes, why? I thought by wiping the modem get's wiped too?

sorry 4 my bad english.
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
No, by wiping via twrp you not wipe the specific firmware parts like modem, you'll stay forever on the modem you got by the last installed OOS version, there was even a specific firmware sided fix for congstar a while ago...

So flashing the latest modem would be the very first choice, especially when you already excluded Google Contacts... Check my signature for firmware, open and go to 2nd post, unofficial firmware zips, around 40mb, flash 3.5.9 in twrp without wiping anything and see if it works.. A proper EFS backup is recommended before you flash modems/firmware, usually it's smooth as a breeze but you never know, in the suggested firmware thread from Spannaa is a efs (modemst1/modemst2) backup script, upload it to Google Drive to be safe..

Edit: have you checked settings, sim, sim 1 settings, preferred network type? Maybe you messed something there..
[OnePlus 2 Q&A, Help & Troubleshooting] Lump91:
thank you very much. this helps a lot. I will try this firmware.

yes, i checked this many times, the choice there makes no difference. Even after a clean flash with opengapps nano.

after a few minutes i did this with aicp, after reboot the error and furthermore i did't have any keyboard installed, only google voice input did work. lol

edit: tried several firmwares, unlocked additional bands, but no lte.

network drops are even there, altough i have installed gapps nano, no hike, no google dialer, no google contacts.

If i search for networks, i get Congstar and many others, but i can't connect manual. [MENTION=7125933]Sam Nakamura[/MENTION]: "Momentan kann keine Verbindung zu diesem Netzwerk aufgebaut werden"
[OnePlus 2 Q&A, Help & Troubleshooting] Aahan:
Clean flashed AICP. Great ROM, really smooth and while it has less features than RR unofficial, it has most of the features I need.

Wanted to ask one thing though. When I go to enable Bluetooth in QS, instead of just turning on it prompts with a permissions message outside of the QS context. Because of this, it doesn't automatically turn on Bluetooth when I connect my phone to Android Auto in my car. Is there a security setting somewhere where I can always allow Bluetooth to be switched on? I couldn't find any such setting. Or maybe I'm just blind :)
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
You can ask this kind of rom specific questions in the dedicated AICP thread, couldn't tell you right now, exept guessing :) maybe check permissions for android auto (settings -> apps -> android auto) or go to Bluetooth and check when connected, maybe there's a option while connected..

Hey guys,

Have to go back to OxygenOS from Pure Nexus, so I just need to perform a full wipe (including system) and then just flash the full ROM zip?

[OnePlus 2 Q&A, Help & Troubleshooting] abjo:
Hey guys,

I have a problem with my Oneplus 2.. The current ROM which is running on my op2 is CM13 Unofficial from 15.03.2016. Yes it´s quit a long time ago, but now I want to update to Android 7.

Yesterday I thought, that there will be no problems to update my twrp and then flash the new ROM, but it was horrible!

When I tried to flash the a new TWRP image, there was no error, but when i tried to boot the same image via: "fastboot boot twrp.img" there came the error message: "DTB not found". I thought, that i have to turn the phone off and try again, but i came into a loop with the oneplus sign/brand.

Then I tried the TWRP 3.0.2 and it worked. Flashed it, tried to boot (error), restarted and restarted into recovery via power button menu. Then I was in the recovery. There I flashed the newest TWRP image and the same issues came as flashing via fastboot..

I have no clue what to do next. Some answers in other threads and forums say to flash a custom twrp recovery, but this also dont work..
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
I would guess that it's firmware related, what was the last OOS version you installed? You should upgrade oxygenos to 3.6 and then flash the latest official twrp, then go on from there...

Edit:

Take either the full signed flashable firmware or the unofficial firmware only zips (only 40mb) from here:

https://xdaforums.com/oneplus-2/help/qa-noob-friendly-qa-help-thread-t3146584/post72799145

Then fastboot flash the latest official TWRP and you should be fine..
[OnePlus 2 Q&A, Help & Troubleshooting] abjo:
So I should use this version https://www.androidfilehost.com/?fid=889764386195914764 and flash it with the 3.0.2 recovery that worked, or should I flash the original op2 recovery?
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
Yeah, for example but this is the full version, if you don't plan to use oxygenos it would be sufficient to flash this firmware only package with a notably smaller file size:

https://www.androidfilehost.com/?fid=889764386195914770

Either way you're fine with it, you can keep twrp also, 3.0.2 is fine but I would try to update twrp again after firmware update.. By the way on the 2nd post of the linked firmware thread you find a EFS backup zip, as twrp fails to backup this partition properly and you surely want to have a backup, just in case and stupid thing happen from time to time and as you planning to do the first firmware update since 12 months I'd definitely recommend to do it, it's just a matter of seconds..

Edit: there was a bootloader change with OOSv3, which could be responsible for the issues you have, given you're still on the Lolipop firmware...
[OnePlus 2 Q&A, Help & Troubleshooting] abjo:
Okay.. But how do I flash the firmware update? Should this happen with a custom recovery or the standard of op2?

By the way, I cant install the 3.0.2 now, I don´t know why, but it doesnt work..
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
You could flash the official OOS builds with with TWRP, no problem...

So what's the situation now, does cm13 still boot?

You got any recovery available and if which one?

What means you can't flash TWRP again, what's the error it shows?

- please be as specific as possible!
[OnePlus 2 Q&A, Help & Troubleshooting] abjo:
The problem is. that I can´t boot into any recovery! I can flash any recovery, but cannot boot into them. Everytime there is only the oneplus logo and no recovery is shown. So I can´t flash or install any other .zip or .img..

Now a short description for Sam in german:

Habe jegliche Recoveries probiert und bekomme es nicht hin, dass er in das geflashte Recovery bootet. Aktuelle Version ist immer noch das CM13 von März 2016. Auch jegliche Versuche mit Flashify haben nicht funktioniert.. Ist mein Handy softbricked?
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
Please try to flash hybrid twrp, it was created to solve the different bootloader issues, check here:

https://xdaforums.com/oneplus-2/general/recovery-twrp-3-0-2-hybrid-supports-oos-t3362904/page1

If that doesn't work you can try to flash the pure stock recovery either from here

https://forums.oneplus.net/threads/oneplus-2-stock-recovery-image.383206/

or you search for the version according to your last installed OOS...

With a last resort option using the official oneplus unbrick tool to reset the device to stock OOS 3

https://xdaforums.com/oneplus-2/general/guide-official-op2-stock-reset-to-oos-3-t3402020/page6

-----------

Edit: also the possibility to fastboot flash / adb sideload a full firmware image could be a alternative, you're still able to enter fastboot mode? Take your time, check each option with unbrick tool as last resort, backup important data from internal storage, your device is definitely not lost :)
[OnePlus 2 Q&A, Help & Troubleshooting] abjo:
Oh my god! The second way worked great :) I flashed the stock recovery and than the stock OOS 3.0.. After this, I could flash every recovery that I want. Thank you so much! I love this community :highfive:

hi

My oneplus2 has 3.5.8. i want to upgrade to 3.6.0. i have downloaded the 1.18gb. i have twrp installed. i have copied the update and the latest twrp update to phone. i want to know the steps to upgrade with out losing any of the data.

if i follow these procedures i am writing below will i lose data..? (i never wiped caches while upgrading from 3.5.6 to 3.5.8)

1. Wipe cache and Dalvik cache files

2. Flash Oxygen OS and super su

3. Wipe Dalvik & Cache again

4. reboot
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
1. Wipe cache and Dalvik cache files

2. Flash Oxygen OS and super su

3. Flash twrp image (with TWRP install image option, place it in recovery section) and reboot to recovery

4. Then reboot to system

-> flashing twrp right after updating OOS will avoid twrp to be overwritten by stock recovery, you won't lose data as long as you don't wipe internal storage (which shouldn't be done anyways)

Help please - random restarts

Hello,

My OPT has many random restarts, I don't know what to do, I tried different rooms and nothing helped so far.
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
Make sure you do a clean flash of each rom you start with, clean means to wipe everything except internal storage (twrp -> wipe -> advanced wipe),

leave any mods out for the beginning and only flash rom and small gapps packages (like opengapps Nano or Pico or beans mini),

further make sure to be on the latest firmware (search the thread for flashable firmware zip or search for Spannaa's OOS thread, post 2 in specific)...

Give it a try and report back if you have still the same issues! Good luck..

How to disable the notification light while charging ?
[OnePlus 2 Q&A, Help & Troubleshooting] 0v3rl0rd:
I was having the same problem. There is no "easy" way (i.e. stock option) to disable the charging LED. Here is the only solution that works excellent:

1) Unlock the bootloader, install custom recovery & root Your OPT: GUIDE HERE.

2) From THIS LINK download an install (in this order):

xposed-v74-sdk22-arm64.zip >>> install this from TWRP recovery

XposedInstaller_3.0_alpha4.apk >>> install this when booted normally

3) Download and install this xposed module: LINK HERE.

That are all installations. Now about setting:

4) Open the XPOSED INSTALLER application

5) Once in the app, click FRAMEWORK > window should pop up (click OK). In the next window it should say "Xposed framework version 74 is active". Go back.

6) Click MODULES and check the mark on the GravityBox[LP] module.

7) !IMPORTANT! >>> reboot the phone

8) Once the phone is on again: open the GravityBox[LP] application >> POWER TWEAKS >>Battery charging LED >> set it to DISABLED

That's about it. Looks hard but it's pretty easy ;)
