Hola amigos!

Wanna buy a pre-owned model of this phone. Dreaming about it about a year.

A seller said, that he have a dash charge (quick-charge), but it stop working few weeks ago (just no any mentions about quick-charging on a phone display) and he bought a new original usb-c cable, becasuse he thought, the problem is in it. But new cable did nothing.

What do you think? Can this be a problem with a phone?

Or I can buy it, just ask a little discount for non-workin quick dash charge? :(

He took me a very good price and I don't wanna miss it...
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
Sure, go ahead and buy it :) the oneplus2 has no quick/dash charging, that's why it isn't working...

one plus two stuck on boot logo

i had LOS 14 installed. someone from group suggested me to update TWRP So as to update LOS to 15 so I updated TWRP. later i decided to reboot it but it stuck on logo. i don't know what to do? I cant even boot in recovery mode.
[OnePlus 2 Q&A, Help & Troubleshooting] kavee.gauravjoshi:
How did you update to latest TWRP? While flashing latest TWRP image, which partition did you choose - boot or recovery? If by mistake you have chosen boot partition, then you might get only oneplus logo and mobile won't boot. Of this is the case then you will need to flash the latest TWRP using fastboot mode + computer. Not sure why are you facing this issue. May be it will be better to tell exact steps...
[OnePlus 2 Q&A, Help & Troubleshooting] 712aniket:
ive updated it through TWRP official app.

ive updated it through TWRP official app.
[OnePlus 2 Q&A, Help & Troubleshooting] kavee.gauravjoshi:
I'm not sure why this is happening then. Might be incomplete download. If i were you i would try following steps-

First option is to wait if someone more experienced gives you better advice. I am also sharing options based on my limited knowledge.

1. Try to long press the power button, for around 40 sec to totally switch off the phone

2. Now try getting into recovery using power and vol down button

3. If cannot get into recovery, then again go to step 1

4. Then check if fastboot is working. So press power and volume up button. If even fastboot is not working, then follow this guide - https://forums.oneplus.net/threads/...ck-guide-for-a-hard-bricked-oneplus-2.347607/

5. If i can get into fastboot mode, then connect to laptop and flash recovery using steps mentioned here - https://www.google.co.in/amp/s/xdaf.../guides-how-to-guides-beginners-t3146568/amp/

Sorry, I couldn't help you much....
[OnePlus 2 Q&A, Help & Troubleshooting] Droidriven:
Use Flashify to flash TWRP instead, the official TWRP app is known for not working well.
[OnePlus 2 Q&A, Help & Troubleshooting] 712aniket:
can i atleast recover data before i could follow those steps? to ensure no data loss.
[OnePlus 2 Q&A, Help & Troubleshooting] 712aniket:
I've tried the procedure to install official rom through ADB devices but the thing is install was success but phone shows main menu only ang again restarts and it continues.
[OnePlus 2 Q&A, Help & Troubleshooting] Droidriven:
After flashing the stock firmware, boot to stock recovery and factory reset then wipe cache and reboot, sometimes fixes that issue.
[OnePlus 2 Q&A, Help & Troubleshooting] Droidriven:
If you can get the device to connect and access the storage on the device and use data recovery tools then go ahead and see if it works
[OnePlus 2 Q&A, Help & Troubleshooting] 712aniket:
does factory reset wipes all the data on the phone???

because when i flash stock firmware and booted my phone it started for about 1 min there was all the data and apps included. after that restarted again and bootloop continues.

---------- Post added at 09:17 AM ---------- Previous post was at 09:15 AM ----------

can i backup my data with fastboot mode or sideload mode?
[OnePlus 2 Q&A, Help & Troubleshooting] Droidriven:
Yes, factory reset wipes all of your user data and saved settings.The bootloop is probably being caused by some kind of saved setting or data in data partition. You probably have to get rid of it to get it to boot normally. Yes, you could backup your data before factory resetting but restoring that data after factory resetting would more than likely just cause the issue again because the data causing the issue would be saved In the backup, its best to just wipe and take it as a lesson learned.
[OnePlus 2 Q&A, Help & Troubleshooting] twfs:
Hi recently got one of these phones and really like it so far. Phone already had twrp installed and a custom ROM on it. I have tried several nougat and all the Oreo ROMs on it and they all recommend being on the latest firmware and for the life of me I can not find where that information is when running a custom ROM. Sorry if this has already been answered but couldn't find anything using the search function
[OnePlus 2 Q&A, Help & Troubleshooting] Spannaa:
There are firmware zips in the second post of this thread, the latest being the OOS_3.6.1_Firmware.zip
[OnePlus 2 Q&A, Help & Troubleshooting] twfs:
Thanks for the reply how do I check and see if I am not already on the latest firmware?
[OnePlus 2 Q&A, Help & Troubleshooting] Spannaa:
You can't tell exactly what firmware you're on - the only indicator is the baseband but some radios have the same baseband number!

If in doubt, just flash the latest and remember what you flashed.
[OnePlus 2 Q&A, Help & Troubleshooting] twfs:
Ah thank you that was what I was trying to figure out
[OnePlus 2 Q&A, Help & Troubleshooting] cjcool_123:
Best stable nougat from for this device? With great sot and everything working on the ROM?
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
Maybe mention that device in first place would help but I guess this can actually be answered regardless, there's no best ROM, Kernel or whatever, it always depends on your needs and what you trying to achieve, best battery life? Will probably lag and isn't suitable for gaming...

Best gaming experience? Will probably drain your battery and isn't suitable for every day usage, a balanced middle?

Again depends on your set-up, installed apps and general usage patterns...

It's about trying yourself, use a custom recovery and backup your stuff, this way you can try all sorts of ROMs and return to your previous and working setup, in case you're not satisfied :) xda is a place to learn and grow by trying and making mistakes (avoid them if possible :silly: lol) and most importantly, learning how to fix stuff yourself - it's not a place to be told "what's best"...

Good luck

hi, i have a OP2 on custom rom currently rooted with magisk.

is there any way that i can revert back to stock OOS, together with wiping all data in internal sd? like a brand new phone with stock OOS?

thanks in advance.
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
Sure there is...

Just download the latest version of OOS from here

https://forums.oneplus.net/threads/mirrors-for-official-oxygen-os-roms-and-ota-updates.387615/

Make sure to use TWRP's advanced wipe option and check all checkboxes, except internal storage (if you decide to wipe it you'll need a working OTG USB or PC to transfer the files to your phone)

If you flash the full signed flashable zip of OOS and reboot your custom recovery will be replaced by stock recovery, phone will be on OOS...

-------------

Alternatively follow this linked thread:

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

This would be my weapon of choice :laugh: as it will also lock the bootloader and it's described how to reset the "tamper flag" (optional and rather risky) but it returns the device back to a total factory like state with clean OOS, locked bootloader and clean tamper flag...

Menu and back capacitive button doesnt work

Hi everyone, I need help with the capacitive button on my OP2 (A2001). Since the day I bought it it was already not working (and not light up). So i thought the button flex located behind the lcd was the culprit. I bought the part and replace it. But still it doesnot working. So I ask the seller to send me a new flex since I thought the 1st flex is malfunction. When the 2nd flex arrives, i replace it but, no nothing, still doesnt work. FYI, I am currently running Lineage OS 14.1 but the issue persist when I use OOS 3.6.1. Any suggestion anyone?
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
You basically did the same as shown here?

[youtube]Eu77ZPwq-qU[/youtube]
[OnePlus 2 Q&A, Help & Troubleshooting] m91c:
YES!!. Exactly, I did refer to that video. any suggestion mate? :D BTW i ordered the flex from aliexpress, it seems everyone else are happy for their purchase based on the feedbacks.
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
Have you manually checked them on OOS, I think *#808# is for manually testing...
[OnePlus 2 Q&A, Help & Troubleshooting] m91c:
No i didnt, and i dont want to go back to oos, as Lineage was perfect for me now. i am pretty sure it was hardware issue. anyway, i will try to change the mic board later. Thanks for your suggestion!
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
Well, switching back to OOS for testing isn't a big deal, just backup your set-up in TWRP and clean flash OOS followed by the TWRP img (to prevent stock recovery from overwriting TWRP), you could easily move back to your previous backup after testing...

Anyway, I think you're right, if the replaced LEDs still not work you'll have to work all the way up to the Mainboard, along the line of connection, as much as possible, somewhere is a faulty connection - testing would only be interesting for one reason, what diagnosis would it present? Maybe it gives you a better idea of where the actual issue is...

Edit: just checked and manually testing doesn't give you any further information, it either works or not... So..

Cant Flash Roms Through TWRP

I unlocked the bootloader on my OP2 and installed TWRP Recovery ( 3.2.1.0). I Want to flash AOSPExtended Rom v4.6 (Link).

When I try to flash the ROM, I get this screen

Screenshot - https://imgur.com/X7Xh24p

and nothing after that

No Error at all. It just goes on until I force shut down TWRP. It's not the ROM as the same happens when I try to flash other ROMs or Zip files.

Did I miss something while I was unlocking the bootloader?

​

Just incase these are the steps i followed:

Installed ADB tools

Enabled Developer Options ( OEM Unlock , USB Debugging )

Using ADB, Unlocked Bootloader

Rebooted the phone and booted back into Fastboot mode

Flashed TWRP

Any Help on this matter would be Appreciated.​
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
By "deleting your contacts also saved contacts are deleted" you probably mean when deleted from the contact app it's also gone from Google cloud contacts?

Check your settings of the contacts app there are settings for merging contacts and also if they should be deleted completely - actually you should mention which app you're using for managing your contacts (also a search on Google would be helpful, use the app name and a brief description of the issue)

Clean flashing always means to use TWRP:

-first make a backup of your set-up, tap backup and check boot, system and data, if anything goes wrong you can just boot back to TWRP -> restore and choose the recent backup file

-boot to TWRP -> choose wipe -> advanced wipe and check system, data, cache and Dalvik/ART Cache -> swipe to wipe

-now go back to install and choose your ROM, add your GApps package (add also root like Magisk or SuperSU) and swipe to wipe (all Zips in one row or at least one session)

-Go back to main menu and choose reboot and reboot to system

First boot takes a while be patient!

---------- Post added at 06:24 PM ---------- Previous post was at 06:19 PM ----------

You did nothing wrong, the screenshots tells you that TWRP had an error with loading the English language package - so it just can't go on as it's missing the words or hangs because it cannot load the English set, that's what I assume - make sure you're on the recommended firmware, have flashed latest OOS (or the corresponding firmware package) before flashing this custom ROM?

But it's probably the best guess to use a more recent ROM, the one you're using is from mid 2017 and very likely not compatible to latest TWRP, I'm pretty sure that's the actual issue, so downgrade TWRP to 3.1.1 or use a current ROM, TWRP 3.2.1 is for latest ROMs (Oreo) - this is very likely a compatability issue...
[OnePlus 2 Q&A, Help & Troubleshooting] SpeedOfShadow:
Thanks for the quick response,

To answer your questions:

​

If by recommended firmware you mean the latest update, you mean latest OOS then yes. My settings app mentions that it is on the latest version. Screenshot - https://imgur.com/a/nENeU

I was under the impression that TWRP is backwards compatible so shouldn't the latest TWRP be able to flash any ROM which its previous version could. Maybe I'm wrong there haha.

Here are some of the things you mentioned that I tried:

I tried to select the English language in the settings menu of TWRP and that seems to rectify the error with loading English package. But this does not fix the issue. I still have the same problem now but without the English error. Screenshot - https://imgur.com/a/405v0. This could not have been the problem as I get a log in English when I wipe memory or do other TWRP operations.

I Tried downgrading TWRP to 3.1.1 and no luck there too. I get the exact same error in the downgraded recovery. [This OP2 is my brother's phones and I Use a Nexus 5 as my daily driver. I could flash Paranoid Android (7.1) and AOSP Unlegacy (8.0 and 8.1) with the same TWRP (3.2.1) on my Nexus 5. This should mean that TWRP is backwards compatible imo.]

I Noticed some other stuff which might help you :

As I have mentioned in my first post, This issue doesn't seem to be confined to just ROMs. I Tried flashing Magisk(15.3) and I get the Screen with no text.

I tried a different language, in this case, French ( as I understand a bit of it). And I get the same screen. Screenshot - https://imgur.com/a/zzvlU

The other thing I have found is that I can use ADB sideload to flash zips. I could flash Magisk using this method. Screenshot - https://imgur.com/a/bzoyL . I'm not sure if this is a safe way to flash ROMs though so I didn't flash any ROM yet.

I Tried searching for a solution online but nobody seems to have this issue. And more importantly, I have no idea what to search for as there is no error message.

Let me know if there is anything else I could provide that would help you. Thank You :)

PS: Sorry for the lack of hyperlinks as XDA rules don't let me post links if I don't have enough number of posts.
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
Thanks for your detailed answer and theoretically your right - TWRP tries usually to keep backward compatibility, at least as much as possible, latest development necessities might break compatability to older android versions / ROM as the aim of every TWRP version is first of all to support the latest/current Android version...

It's also hard to draw direct conclusions from hammerhead to a OP2 (SD 800 vs 810), different kernel versions, architecture, etc. means also different outcomes..

Anyways, your issue is starting to give me headaches as I don't see a obvious reason for this error, to recap:

Using another TWRP version throws the same error at you?

Flashing i.e. latest lineageOS gives same error output?

Try to delete the (hidden) .twrps folder in /sdcard/twrp, this will reset all settings previously made in TWRP, it will appear like you flashed TWRP the very first time, check if error still persist...

In the meantime I'll see if I can find something in the OP2 forums about this specific error

Edit: here's a actually maintained TWRP in a sense that a real person reviewed the code and anupritaisno1 is long enough in the game that I have no worries to recommend her work, you could give her modified version of TWRP a try:

[OnePlus 2 Q&A, Help & Troubleshooting] SpeedOfShadow:
Thanks for your efforts so far.

To answer your previous questions:

I tried various versions of TWRP including the one you recommended ( by anupritaisno1). The same Issue still persists. Screenshot using modded TWRP - https://imgur.com/a/yuEHN

I tried Flashing Latest Lineage OS ( 14.1-20180126) from their official website ( https://download.lineageos.org/oneplus2 ) and still get the same issue.

I tried deleting TWRP Folder to reset the settings as you suggested. No Change after that. The Language error no longer exists though as I selected the language as soon as I booted into recovery.

Some interesting things I noticed:

I am able to use Sideload to flash ROMs and Zips. I Flashed AOSPExtended and LineageOS using sideload without any issues.

While using Sideload I can see the log running on TWRP. The same Log doesn't show up without sideload and i flash normally using TWRP.

I tried flashing the stock OOS from the Oneplus official website ( http://downloads.oneplus.net/oneplus-2/oneplus_2_oxygenos_3.6.1/ ) and even that gives me the same problem.

All other functions of TWRP seem to be working just fine. There are no issues with the ROMs I flashed using Sideload too. I would still love to find out why this is happening and preferably solve it as I don't wanna depend on a pc whenever I wanna flash something.

I currently flashed enhanced TWRP and LineageOS 14.1 ( I like its update frequency and my brother likes the boot animation so we're sticking to it :) )

Thanks again for the help. As usual, let me know if I can provide you with any extra information.
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
You can pull a recovery log after triggering the error....

After this error appears go back to TWRP main page and go to advanced -> copy recovery log to SD

Check yourself or post the log here or to a different appropriate section, for example post it to anupritaisno1's thread as it also occurred with her custom version and she's good at reading logs, also the G+ page of official TWRP is appropriate...
[OnePlus 2 Q&A, Help & Troubleshooting] SpeedOfShadow:
I tried doing this, but there is a problem. Whenever I select a file to flash and swipe to confirm, TWRP displays its output log and nothing else. I don't have navigation buttons nor an option to go back to the main menu. I usually terminate it by force shutdown using power and volume down button.

When I reboot into recovery I am assuming that the logs will be refreshed.

This is the log I got after trying to flash a ROM and force shutting down and Restarting TWRP.

Let me know if there is a way to go back to TWRP from the log screen ( not sure what that screen is called).

I'll be posting the logs on the sites you mentioned and will be linking them below if anyone is interested in following.

I am currently on Pixel Experience ROM (latest March update). Instagram app is extremely slow to load on WiFi. I have a 90 Mbps WiFi connection plan and I get close to 30 Mbps as tested in speedtest app. But images and videos are extremely slow to load.

1. Uninstalled and installed app

2. Deleted cache and app data

3. Deleted cache and dalvik in TWRP

4. Clean flashed the ROM

BTW this wasn't a rom related issue as I faced the same thing even in the stock rom and my mother's Honor 7X

5. Factory reset the WiFi router

6. Changed the DNS to 8.8.8.8 and 8.8.4.4

7. Changed the DNS to default, OpenDNS values as well

Nothing improved the speed.

Point to note, YouTube, Facebook and chrome works flawlessly. Instagram app on my laptop connected via LAN works flawlessly.

I had put network speed checker and saw that whole using the instagram app to see stories and videos it was drawing max 20 Kbps but other apps I see 2-4 MB/s. Any help? Does anyone face the same problem?

It has to be something about the app or your device settings, it isn't a connectivity issue. Probably some kind of service in the app hogging data and bandwidth.

Hi Guys,

I am trying to transfer firmware to my OnePlus 2 via adb sideload after my phone got into a poweron loop. I deleted all the data on the phone.

Now it does not finish the firmware load it returns error "* failed to read command: No error"

How can I overcome this. Please help.
[OnePlus 2 Q&A, Help & Troubleshooting] Sam Nakamura:
To help you more information is needed....

Why do you need to sideload it actually, what about stock recovery or "fastboot boot recovery twrp.img" to have it available temporarily (in case stock recovery fails) to flash full OOS?

Are you bootloader unlocked?

What was the phone running before the sideloading failed? (which OOS modem/firmware version, custom ROM)?

What was the exact command / error, maybe post a picture or copy&paste it.
[OnePlus 2 Q&A, Help & Troubleshooting] jamespropa:
My phone got into a bootloop.

My bootloader is locked. I do not know how to unlock it via command prompt as I do not have access to the phone. It does not boot.

I ran the MSM tool. After went into sideloading and that is where it fails.
