Downgrading from Android O DP2 to 7.1.2 no TWRP

I was enrolled in the Android O Beta Program and followed these steps but can't get TWRP to boot:
• Un-enroll from O beta
• Take OTA to downgrade to 7.1.2 N2G470
• Set up system (dev. options, enable USB debugging, etc.)
• fastboot boot twrp-3.0.2-0-RC1.img
• Boots in to TWRP but doesn't go passed splash screen (after waiting more than 30 minutes)
Not sure if I have to re-flash nougat bootloader, radio and img. Any help is appreciated, thanks!

It's a known issue with TWRP with way O repartitions your phone even after downgrade. You'll have to wait for an update to be released to accommodate the changes in partition structure.

You'll have to flash the factory images from April or May to both slot before it will work again properly

This is correct.. all you need to do is flash the factory images to BOTH slots and you'll be good to go.. I went through this issue myself and once I did this, everything is back to normal

I've tried multiple times to get this booted to both slots and can't seem to get it right. Can you provide steps how to flash to both slots?

I use the unified android toolkit. I'm just learning all of this myself but I know there's a guide on here somewhere that can explain it better than my self. I believe it involved getting the factory image and removing the -w from the flashall file. I'm sorry I cant be of more help!!

Thanks, I'll look around, but if anyone has a link I'd appreciate it

In my experience if you flash the factory images twice it's flashes to both slots

Finally got the image flashed to both slots. Now for some reason I always get a bootloop after flashing the twrp installer. fml

On the May update?
You need to install the zip from inside twrp that is in the first post of the thread below. Need to do that when you root, twrp or change kernels.
So fastboot boot to twrp again and adb push the zip to the phone and install it.

Yup, I was on the may update, had no idea they changed anything up in May. What I did was reboot the system, download the twrp zip, fast boot back to twrp and flash the zip, resulted in boot loop. I'll try flashing the verified bootsigner later and if that doesn't work, I'll try rolling back to April.

Flashing the bootsigner did the trick. Thanks for all the help!

enrolled android beta program for almost a day, battery consumes very much.
Now flashing the full May image, but after finishing flash, the phone can't boot into system.
It persisted in four turning dots for almost half an hour.
Tried to re-flash the may image, it did no help.
What should I do, mate?

Sorry man, I've been away from my computer for a couple days. Glad to see you got it figured out. What worked for me was booting into twrp from fastboot, flashing the twrp zip, flashing the latest bootsigner zip from CF, reboot recovery then following the steps to flash PA + gapps that I had downloaded previously.:good:

TWRP encryption problem

After i wanted to install Android P, i got a bootloop. so i wanted to go to twrp but now my files are encrypted and twrp is not asking for a pin or pattern so i can't decrypt my internal storage files.
Now the biggest problem is that i just came back from a family weekend and i made a lot of pictures, witch i can't acces now, and i really want them back.
Now i can't install a new os or anything ...
Can someone please help me! i'm really despirate
(sorry for my bad english)

Try downgrading twrp , night get it to ask for pin

downgrading is never the answer. In fact, that will cause this problem to happen. Now i must ask, are you temp booting twrp or is twrp installed to phone.

I got this when I temp booted the mtp enabled twrp the other day, although it still asked for my passcode and said description was successful. When I rebooted the installed (official) twrp it all came back....

Now i am booting from temp twrp, before that i got the latest twrp installed

Bringing this back up... Did booting from temp twrp work? Ran into the same issue.

Temp boot and use the usb c to pull ur data from the device to a computer. After that you can wipe and start over. Unbricking guide available in the help section

Having the same issue. If I boot using fastboot TWRP I'm able to decrypt data. I did that and flashed stock OOS and the same TWRP version (BluSpark) that was used in the fastboot. But the folders are still encrypted. It's weird how a fastboot can decrypt it but a regular recovery boot can't. Is there any alternatives available?
I'm in the process of backing up my data before I officially bite the bullet.

Only way i know to get rid of this by removing the encryption on the data is to Format the Internal Storage !

That's what I did in the end. I just backed up my media through fastboot TWRP beforehand. Beats having to use the download tool at least

Probably the best way indeed. I think i'm gonna start disabling forced encryption to stop these kind of problems.

No OS installed in TWRP

Hi guys
I was trying some of custom rom on my OP6 and I wanted to go back to Oxygen OS. So i did a clean installation with system wipe and i flashed the last full OTA update. But since i can't boot to system anymore, TWRP always displays that there is no OS installed despite the fact that I've tried several rom . Is this the first time it's done this to me how can I fix it?

The best suggestion I can give you is to flash stock oos with TWRP, reboot to stock recovery, without flashing anything else, wipe data from stock recovery and startup system.. if it is working you can flash back TWRP and magisk if you need it
Just be careful because at your point is easy to lose all of your stored data

If you wipe system, then flash oos ROM, TWRP will think there is no os. You can just ignore and boot.

Wiping system then flashing any time will make twrp display "no os installed" it does this because it hasn't created files for twrp to check if you have a ton installed. Flashing twrp then rebooting to twrp fixes it.

Reboot to stock recovery?

Hi, need a little bit of support, since I'm new to this as well. I was in a working OOS open beta 25/28, but then I think I flashed the wrong zip (OOS 9.0.9?), and I was not able to boot to system. It kept going to "bootloader unlocked" screen and custom recovery. Currently in TWRP blu_spark 3.3.1-x v. 9.109, and it's showing me no OS installed when I attempt to reboot. I haven't rebooted to system yet.
All the folders in my /sdcard is gibberish... if I try to push a file to it, it says "Required key not available." I did remove all security/passwords from my phone before doing any updates/backups.
I completed a wipe cache/dalvik/system via TWRP, and flashed the OOS OTA stable Android 10 zip downloaded directly from OnePlus Support. Considering this situation, do you still think it's safe for me to reboot to system? Then how do I get to stock recovery from there--is that by holding down the buttons?

No, your internal storage Is like trash cause the last rom you flashed has older security patch than oos10. Your device Is now encrypted and wont boot to system. I Guess you have to erase all via MSN tool or fastboot signed rom. Even if you wiped what mentioned above, your problem still be the data.

Fastboot method?

Thank you for replying. I'm relieved that you know of a couple methods to try.
Is using "Format Data" in TWRP an option for dealing with the encryption??
For the MSN tool, can I use this one? Tried looking around, but it's unclear. "[TOOL] MsmDownloadTool V4.0 International (Oxygen OS 5.1.5)" https://forum.xda-developers.com/on...wnloadtool-v4-0-international-t3798892/page10
I would be more comfortable with using fastboot, but am I at any risk of having lost fastboot, or can I just turn off my device from TWRP right now and hold down the buttons to get there? Afraid to move out of TWRP right now, in case I can't get back. I do have twrp-3.3.1-18-enchilada-Q-mauronofrio.img that I can run from fastboot if needed.
By "signed rom," do you mean I can simply flash one of the zips here from fastboot? "[OnePlus 6][ROM][OTA][Oxygen OS] Mirrors for official Oxygen OS ROMs and OTA updates" https://forum.xda-developers.com/oneplus-6/how-to/oneplus-6-mirrors-official-oxygen-os-t3792244

I hardbricked my device about 10 times and i was able to recovery It even from a blank screen. Btw format data Will erase all your data but also the internal storage. About fastboot dont be afraid, go under twrp reboot section and reboot to bootloader. Then go under xda op6 guide section and search for mirrors for fastboot rom guide by Mauronofrio. He pushed my ass out the **** a lot of time.
P.s. Sorry but I dunno how to paste a link via xda app. Yes, ik! It's a vert newbie thing.

That's awesome, I'm starting to grasp how much of a genius Mauronofrio is, after so many people referencing his work.
In his guide, he says, "These ROMs can't be used to update or downgrade your phone but just to restore your phone, so don't use them to come back to oreo or to update from oreo to pie." This may be a dumb question, but how do I know which zip/OOS version to flash, when I don't have a functioning OS on my phone?

I talked with Mauronofrio in pm and he said me that you could solve your issue simply flash the ROM you want and format data after flash that one. Remember that your internal will be wiped but it would happen in any scenario we talked.

That worked! And starstruck that you were able to check that with him. I flashed Mauronofrio's fastboot ROM for 10.3.2 and it rebooted (WOW). I clicked through the Google setup pages and checked that my data and wifi worked.
I then went back into fastboot, booted M's twrp img, fomatted data, and then installed twrp-3.3.1-x_blu_spark_v9.109_op6.zip, rebooted into recovery.
Then I think I made a mistake, because I installed Magisk-v20.4.zip. It succeeded, but now I can't boot into system anymore. Is it too late to flash the 10.3.2 boot.img?

Hey,
I bricked my OP7 after what seemed like successfully installing and using Android 11. I am getting the Teamwin blinking brick.
This(

to flash the latest stable build on OnePlus support, i.e. this-

Or do you suggest to use the Android 11 firmware available on XDA?

I am pretty sure I know my OS, but is there a way to find out?
I was running the stable, but flashing stock boot just led me to a boot loop with the Original Recovery, it's giving me options to
1. Wipe data and cache
2. Reboot to fastboot
3. Reboot to recovery
The fastboot flash commands above to flash stock OS didn't work, due to one error or another.
Anyhow, I had read somewhere fastboot continue works(here: it wasn't working before for me), so I tried that again, and now I am just stuck on 1+ Fastboot screen. I will wait it out to see if it boots into system.
Otherwise, I am thinking I reload fastboot and flash stock boot just like I did- and from there wipe data, but what do I expect then??
The way I see it, I am just stuck in some serious boot issue, and might eventually have to go down the path of msndownloadtool, any suggestion?

I am pretty sure I know my OS, but is there a way to find out?
I was running the stable, but flashing stock boot just led me to a boot loop with the Original Recovery, it's giving me options to
1. Wipe data and cache
2. Reboot to fastboot
3. Reboot to recovery

Flashing the stock boot.img should be enough to boot into system without problems because TWRP can't decrypt data in android 11.
In this point you can try a factory reset from stock recovery this will keep device files but will erase all your config and apps
To figure out what version of firmware you had you can run this command in fastboot
Fastboot getvar all

Flashing didn't work to boot into system, I was just getting stuck in the Recovery boot loop, it finally booted into system once I wiped my data(files, music, etc -option);
I did try factory reset, only once I cleared the partition, did the boot loop give way to boot into system;
It booted back to Android 11, but it's all glitchy: Boot taking too long, WiFi not switching on, Call not working, Data is working though- basically it's very screwed up, got a couple of errors too- it's like watching an amnesiac old person.. if you get the gist.
So, now I am considering a stable build from Oneplus support website as a local upgrade and booting back to that..
I am hard pressed for options, let me know if you think something else works better, thanks!

I guess msmtool it's the best way to restore your phone, remember that msmtool will re-lock your bootloader so if you want root you need to unlock your bootloader again.
Use msmtool and instructions form Here(there's an android 9 and android 10 for Global and Europe versions, use android 10)

This is the OnePlus 7 pro forum so, I assume you was a 7 pro user, now all makes sense you don't flash the correct boot.img for your device so all woes wrong.
You need to use msmtool from Here

Hey, I am on Mac, I see that Msm is windows-specific.. any way out?

Update: I have been roaming around the corridors of this forum since about a week now. Thanks @RokCruz !!
Finally, used msm tool, although I suspect I still had the option of flashing TWRP and Magisk as I had access to phone and fastboot, but the system was super glitchy.

[SOLVED] Need help, recovery flash failed (Newb)

Hey Guys,
I got a new OP8T and wanted to install LineageOS 19.1 (First time doing something like this, so this might be a dumb question).
before doing anything, I updated OOS to the latest version using the internal update. I then unlocked the bootloader and flashed the latest LOS recovery. After flashing the LOS recovery, my phone goes into a boot loop whenever I try to boot it, after 4-5 loops, it boots into the stock recovery.
I can access fastboot mode though. Does anyone have an idea how I can fix this or what I might have done wrong?
In the recovery I have the option "format data". Might that do a factory reset?
Or should I go into fastboot and try flashing the recovery again?
I also thought about flashing Android 12 OOS from: https://forum.xda-developers.com/t/rom-official-kebab-12-lineageos-19.4484387/page-2#post-87339737
I'm a little afraid to completely bricking the phone now by doing something stupid.
Edit: Tried to "format data". No real changes. Can still boot into recovery and fastboot.
Another thought I had, was that now, after factory resetting, the phone might be back to Android 11, so maybe I could try to flash TWRP for Android 11 and then LineageOS 18.1?
What are your thoughts?
Edit: Forgot to flash the vbmeta.img and dtbo.img partitions.
Flashing them and then flash the recovery again resolved the issue

A factory reset does not downgrade your OS version. Did you flash the dtbo and vbmeta partitions before flashing LOS recovery?

It's a good thing to look through the official thread before flashing anything.

No, I didn't. That was definitely the mistake! I feel pretty stupid right now.... Oh well...
Can I do that now and then flash the recovery again? Thank you!

I thought about using the msm tool to reset the device completely, but that seems kinda drastic...

What I would do is go into fastboot and flash dtbo, vbmeta and recovery downloaded from here, then reboot into recovery directly from the bootloader menu.

Is that the same as the most recent recovery and LOS from LOS official download page?
Anyway you're a huge help! Thank you so much!

The file name is identical so I suppose they are the same. I found the link in the official guide.

I'll go ahead and try it first thing tomorrow morning

Don't be too anxious about "completely bricking" your phone if you're just trying to upgrade and then flash Lineage. Don't rush, try some things that make sense based on your understanding of the correct procedure, and make a brief note of each step you took to help you later on if things don't work as expected. I've made lots of mistakes ending in boot loops and crash dumps, sometimes by accident and sometimes intentionally, and there's always a way to get out of it unless you do something really out of the ordinary. Keep your mind engaged and you'll have many "Ah-ha!" moments along the way. Don't give up and ask carefully worded questions when you get stuck. It may take a bit longer to get the job done than you expected but it will all work out in the end.

Flashing the partitions and the reflashing the recovery worked! Thank you all for the help!
