Latest way to root moto g3 2015 xt1550 OSPREY

Could anyone please point out a way to root my phone(in title), as of this day. There are many methods. So I am confused. I recently read about magisk manager, used to root. Does it work? I just wanted to know the latest method, easier one of any. Also can TWRP manager be used to flash recovery in phone or should it be done flashing TWRP. Img, file.
Please forgive me if i posted in wrong section.
Thanks in advance.

Use PC via ADB (fastboot)to flash TWRP. Flash Magisk in recovery, then dl Magisk manager from play store.
Magisk works very well.
This all is assuming your boot loader is unlocked.
Good luck.

So instead of supersu, we use magisk?
And I read somewhere also that using magisk we can still get updates to our phones. Is that right?
Also there is a TWRP manager in play Store can we use it to flash TWRP instead of ADB?
Thanks for the steps though.

My experience with TWRP manager has been it breaks my recovery. No idea why so I flashed via PC. Not sure you can still receive updates when your boot loader has been unlocked. Depends on a lot of factors. Someone​else will have to answer that question.

OK thanks.

An unlocked bootloader doesn't prevent you from receiving updates from Motorola. But I think rooting the ROM will prevent installation of further updates.
I don't think Motorola is going to push any further updates. So just do anything you want with your phone (personal opinion).

I've never received a update notice.

I would have to agree... There is little chance of getting another update, and if we did it would just be a simple security update and not important.
And no, even with Magisk you cannot apply an OTA update, it will fail.

Unlock your bootloader, flash the twrp recovery using adb fastboot...then wipe the stock rom, flash custom rom along with SuperSU....enjoy! (Processes are same but you should use the latest versions of all these...)

unlock the bootloader.

I can't, because OEM UNLOCKING is set to off

Thanks for the simplified guide. Worked great, I was able to relock the bootloader and accept an OTA with no problem. Only issue is the device doesn't pass safety net - signature validation error, and when I boot up I get the device has been modified pop up.

same peeps thread

aw man... well, I meant to post specifically to the last post in the thread but was on the mobile app.

:good::good: Just wanted to say thank you for this post, the links to the image files and the flash-all BAT file. This really saved my butt with a Project Fi Moto X4, which I had rooted using Magisk before checking on the availability of factory firmware images from Motorola. (of course there are not any available from Motorola ) The phone was continuously prompting for an OTA update, which would fail. I first tried the Magisk uninstaller, which ran successfully in TWRP, but the OTA update was still failing. After some digging on Google I found your post and used the Project Fi image to flash the phone, it worked perfectly! There was an OTA update available after flashing (The May 2018 security patches, "28.2") and it installed successfully. I love the Android community, the XDA community, and folks like yourself who take the time to write posts like this. Seriously, thank you!

Hello!
I understand you have Android One version. If that's the case, anyone catching the URL to OTA for the Android One 28.2 update? I've been looking for it for days, and the OTA link generator is not working (at least with the data I'm providing which should be correct).

Oneplus7pro back to stock

Hello there,
I tried the open beta on the OnePlus 7pro for a while, but I have some massive issues with speaker distortion, so I decided to go back to stock. I know this involves a wipe of the entire system, and I have fully prepared that.
However: I seem to be to stupid to perform this. I used to flash all kinds of roms to my OP3 back in the day, but I can't find an option for simply flashing the zip in the recovery.
My big big question is: How do I perform the full reflash of this phone?
Do I get an factory rom like with the pixel, or do I need to sideload something and flash it in recovery?
I am really clueless rightnow, expecially since the factory image told me, that the bootloader is locked, but to my unterstandig, flashing an original manufacturer image should not require the bootloader to be unlocked...
So I am really hoping on your help, as rightnow, I have a beta phone that is waiting to be setup...
:crying:

Follow this tutorial.
https://forum.xda-developers.com/oneplus-7-pro/how-to/msm-tool-guac-t3934691

Or easier way would be to download rollback package from oneplus which will wipe everything on your phone. You will have os9.5.3
You can then do Ota upgrade to latest os version. Rollback package is listed in in the middle of the post
https://forums.oneplus.com/threads/...-for-the-oneplus-7-and-oneplus-7-pro.1099154/

So my OnePlus 7 Pro is rooted, has twrp, xxx ROM and renovate ice. If I want to go back stock and relock bootloader, can I simply flash the latest ROM (in this way I should loose twrp and root) and then relock bootloader with ADB command?

Thanks bro!!
Local upgrade is a cake walk! All my worry was, if I go for a random version msm tool, which is not specific to 10.3.4(more like the case of fast boot Roms), i may stuck at bootloop/something undesirable.
From your reply, i understand, i can use any msm tool zip that supports one plus 7 pro, and get back to stock with an older oos version in it. From there i can choose OTA upgrade or local upgrade.. Whichever way? Right ?

Yes I used 9.3.4 and then did local update but if you are on 9.3.4 you have to flash first 10.0.3 and then after that 10.3.4 to upgrade.

Question Downgrade LE2115 from 12 to 11 - confused.

Hello all,
My phone came with ColorOS OOS 12 and I hate it. As soon as I rooted it it started crashing daily, I even reflashed a fresh oos12 image using the local update tool and only granted superuser to one app (solid explorer so I could access user files) and it still crashes. Not to mention all the apps i want to use don't work on android 12 (call recorder, busy box) and no custom recovery.
I've been reading through the forum and I found a downgrade package that looks like its hosted by oneplus: https://oxygenos.oneplus.net/OnePlu...all_2107082125_downgrade_059624cc7298428b.zip
I just wanted to make sure I am doing this correctly...
Do I use the OP Local Update app to flash?
Will I be able to flash TWRP for android 11 afterwards?
Will i need to relock the bootloader?
Should i re-root using the magisk slot b method or wait until its flashed and use TWRP?
Will it try to OTA back to android 12? If so, what's the best method to get on the latest version of android 11?
Thanks for the help.

I am running COS C.62 on my OP9 with root and having no issues. Did you make sure to do all the things in this guide?
Root OnePlus ColorOS 12 OxygenOS Android 12 via Magisk
In this tutorial, we will show you detailed steps to root your OnePlus device running ColorOS 12 Android 12 via Magisk Patched Boot.img file.
www.droidwin.com
Anyway, yes, use the local upgrade APK, put the downgrade file in the root of storage, run it. Reboot. Factory reset and wipe data to clear out any leftover crap (don't restore a backup - if you want to use Clone Phone you can do that but only restore app APKs and messages). When it reboots it should offer the latest OOS11 OTA first. If not, just download it and place it in the root and use the local upgrade function in the settings menu of the OOS11 system updater.
There is no need re-lock the bootloader and if you do, you risk a brick that has to be recovered with MSM Tool.
Root by following the guide I linked. I just went through this yesterday after flashing COS broke mobile data. I have Magisk 24.3 working with denylist, Widevine L1, and SafetyNet passes so I have Google Pay.

Thank you, ill give it a try.
First i used the payload.bin method and it was crashing, then i reflashed the latest OTA using the local update tool and used the magisk slot b method. still crashing.
It might have less to do with the root and more with me using root to disable certain apps (youtube, chrome, OP community, google news/podcast/tv) i dont want them on my phone but they might be too tightly integrated. If its still crashing on android 11 ill re-enable them and see if that helps.

Okay you're on OOS, not COS. COS doesn't have Google apps by default (but has plenty more bloatware, I just don't use it).
It's certainly possible that disabling Google apps is your problem. If you don't want Google apps, you're better off with a custom ROM that doesn't have them. CalyxOS has a beta for OnePlus 9 and it's totally de-Googled. There's also Lineage.

ahhhh. i didnt realize there was a difference. I thought OP was just calling their android 12 build ColorOS.
Either way, for custom roms i would have to go back to 11 to flash TWRP right? or can you flash custom roms using fastboot?

You would need to back to 11 because OnePlus hasn't released working sources for 12. Just use the downgrade package, factory reset, then upgrade to 11.2.10.10 and you'll be good to go for custom ROMs. TWRP isn't used for flashing them, they all generally post their own recovery. StagOS was the best one I used (plus the dev is really responsive when there are issues) and people seem to really be enjoying Nameless but that came out after I went back to stock so I haven't tried it yet.
Before you mess with custom ROMs, make sure that you download the global MSM Tool and make sure you can connect it. Honestly since you have to go back anyway, might as well download and use the MSM Tool to get the device back to 11 anyway.
GLOBAL OnePlus 9 MSM TOOL UPDATED
Frist off Im not responsible for anything that happens to your phone!!! VERY SIMPLE IF YOU ARE BICKED,BOOTLOOPED OR JUST WANT TO GO BACK TO 100% STOCK THIS WILL WIPE ALL DATA!!! AN RELOCK BOOTLOADER OOS 11.2.4.4.LE25AA MUST HAVE QAULCOMM...
forum.xda-developers.com
Easiest way to get it into EDL is adb reboot edl but if you want to practice the key combination in case you can't get into the OS, I found if you open the MSM, check use lite firehose, and click Start before you connect the phone, it has less connection errors because it's waiting for the phone so as soon as you connect the cable, it pops up.

Yeah TWRP has issues. I soft bricked last time I tried to do anything with it and had to use MSM Tool to get back to working order.

Question [FIXED] Hard Bricked LE2115

Background:
I unlocked the bootloader and then proceeded to flash the device from 12 to 11 using THIS tutorial. When I got to the first "fastboot reboot fastboot" the phone never rebooted. The screen is all black. I can't get into recovery or back into fastboot using the button method.
I downloaded the MSM Global tool and got all the drivers installed. I was able to start the flashing process but get "Device not match image" early in the process. I have called OnePlus customer service. They didn't ask any questions just told me to send in the phone. I would rather fix this myself if possible. Any insight and or help is much appreciated.

UPDATE: I found this information, and it had me flash the India 9 Pro version. It worked. I have a booting phone and can now work on getting it back to the US version.

I wish people would stop following the guide for fastboot flashing. Just use the MSM while it still recognizes your device because if fastboot flashing fails, you end up having to flash it multiple times as it's not recognizing it as the correct unit anymore with that level of corruption.
To get back to global firmware, flash this in the local upgrade tool.
https://oxygenos.oneplus.net/OnePlus9Oxygen_22.O.11_OTA_0110_all_2107082125_downgrade_059624cc7298428b.zip
It is the global downgrade package. It will wipe your phone and when it comes back, you will be back on global software.
After you flash that, go to OTA upgrade and it will say it's going to download C.48 but it will actually install 11.2.10.10 and then you will have the latest OOS11.
If you download it directly to the phone or copy it over with a PC, the file may disappear. Enable USB debugging and use adb.

Thanks for that! The phone is back to fulling functioning with the proper version of OOS. It has been a long time since I rooted and ROMed. Fastboot used to be a straightforward method of flashing a stock ROM. Doesn't seem like it is anymore.

Glad that it worked. Did you have the bootloader locked? I am just trying to confirm I'm not crazy and that I was actually able to use it with a locked bootloader lol.
Yeah fastboot flashing was the gold standard way to avoid a brick back in the days before A/B partitions and Android Verified Boot came along but not so much now. This device in particular seems to be really fussy about fastboot flashing. I never managed to brick my Pixel 3 XL doing it but I have had to MSM multiple times trying to do fastboot commands and custom recoveries to flash custom ROMs on my OP9. I have got the process down tova science at this point lol. I just went back to stock and rooted it and I'm much happier with that than I was with custom ROMs that were plagued with issues.

Sorry, I did it with the bootloader unlocked.
I might go back to Stock soon enough. While not as big a pain as Samsung, also not the easiest phone I've played with either.

Yes, you can use this to go back to OOS11. You shouldn't need to unlock the bootloader as this is an officially sanctioned downgrade package.
Since you're on Android 12 you need to install the local upgrade APK:.
https://oxygenos.oneplus.net/OPLocalUpdate_For_Android12.apk
Install that, push the downgrade zip to /sdcard/, open the newly installed system update app, hit the gear, and it should show you the zip file waiting.

There is a pinned post with them. This is C.48 for global and yes, you use the local upgrade but since you're on OOS11, you don't use the APK, use the update function in system settings and tap the gear and you'll see it.

Hi i tried to use the updater on android12 and try to downgrade it to .48 but it return error. So i need to downgrade to android 11 first and then update it again to .48?

Correct. Only the specific downgrade packages can downgrade. It will also wipe the device. There's no way around this. Once you are back on 11, you can do the local upgrade to flash the full C.48 ROM instead of having to do the whole OTA process (normal process is downgrade, OTA to 11.2.10.10 (it will say it's C.48 but have a file size of like 150MB but it's not), OTA to C.48 so you get to skip a step if you just use the full update package).

Ok if i understand correctly, i just use the updater to flash the android 11 zip file that you provided and it will do a full wipe and will restore to android 11. Then i just use the updater again to flasj it to .48
am i correct?

I don't know because I didn't get my phone until February so I went right to 11.2.10.10. It is important to update though because it gets you a working OS on both slots instead of just one.

Lol yeah. I'm not too happy with C.60 either. I really don't want to wipe my device and lose my Signal chats again.

I don't know what you aren't understanding but I'm tired of repeating myself. Read what I wrote and it answers your question.

Ok done it ... on OOS11 now .... no need to unlock bootloader can just flash the file directly.
Will try OOS11 for a while and see if it is worth updating to OOS12
