If you're on crashdump after trying to restore persist..

unfortunately its mean you're ****ed...

I mean there is no way to get out..

Go for RMA
[OnePlus 8 / 8 Pro & 8T Cross Device Development] free4flight:
What I figured too... RMA here I come. Unfortunately...
[OnePlus 8 / 8 Pro & 8T Cross Device Development] flick36:
Dont forget no backup persist image, thats the most important thing to do
[OnePlus 8 / 8 Pro & 8T Cross Device Development] kiki059:
what backup persist image please?

ok i find on Google but how restore after root?

Have fun dealing with OnePlus' ****show when you call customer service. You have to be mean about it to them cause they are worthless. They are the stupidest people I've ever dealt with
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Some_Ghost:
Plug your phone into a computer make sure you have your ADB files up to date, adb reboot fastboot when you are in the bootloader type fastboot reboot fastboot. This will reboot to a menu that is exactly like recovery this is actually fastbootd here you can Flash your persist
[OnePlus 8 / 8 Pro & 8T Cross Device Development] free4flight:
Yes, got it flashed in Termux Terminal... but didnt help... now my phone won't boot at all, stuck in Qualcom CrashDump mode... and the bootloader is locked so I cant use any fastboot commands, msm 4.0 operates but phone does not boot after it finishes...although it managed to lock my bootloader.... screwed.

OEM Unlocking is not turned on in developer settings because msm set everything back to stock but won't boot into stock, if I could somehow get in or somehow turn on oem unlocking, might be back in business, but I sure don't know how to get there.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] :
if you can boot into 'fastboot' mode just 'oem unlock' it from there
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Some_Ghost:
did you try what this other user recommended? oem unlocking in fastboot?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] gaww:
[MENTION=4712355]mauronofrio[/MENTION] - I am sure your are busy all over the place as usual, but just wondering if there will be other tests, or are you working on a final TWRP OnePlus8 Pro version? I will not ask when.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Veestaai:
Could you give the command for back and restore of persist.img?(and how to do it). I guess people were talking of the twrp being able to do the same natively. If so could you show how?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] trial_attorney:
You can use this app to backup and to restore your persist partition.

https://play.google.com/store/apps/details?id=ma.wanam.partitions
[OnePlus 8 / 8 Pro & 8T Cross Device Development] fKm:
That worked for backing up my persist partition. Although restoring with that app did not work for me.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] cultofluna:
Backup

dd if=/dev/block/bootdevice/by-name/persist of=/sdcard/persist.img

Restore

dd if=/sdcard/persist.imgof=/dev/block/bootdevice/by-name/persist
[OnePlus 8 / 8 Pro & 8T Cross Device Development] cultofluna:
To execute "oem unlock" on fastboot, the "allow OEM unlocking" toggle on developer options has to be ON

But he can't boot on OS , he's in eternal crashdump mode

This is happens very often to other users also..

Only solution ... RMA
[OnePlus 8 / 8 Pro & 8T Cross Device Development] bigAL99:
Have to admit I'm very behind on backing my persist file, as in I've just done it. Does the fact I'm already funning a custom rom and kernel mean it's too late?

I'm thinking it's OK as it appears it stays the same and the idea of the backup is to restore it if becomes corrupted.

Am I correct in this?

Thanks.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] cultofluna:
If your persist backup is from a working FP , should be ok..
[OnePlus 8 / 8 Pro & 8T Cross Device Development] janitor9:
So... when i`ll get my phone from repair service i`ll boot twrp as said in page one(after unlock bootloader of course). Then in twrp i flash magisk and reboot. And then use flashify? Or flash installer as magisk module??

Maybe told many many times but now i`ll be very carefull with flashing etc.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] cultofluna:
I only boot twrp when needed..

I've used to flash it temporarily in the past ...

Not any more
[OnePlus 8 / 8 Pro & 8T Cross Device Development] janitor9:

I used it - worked good.

I'm thinking of modifying the name to use it with the "other" TWRP.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] janitor9:
so i boot to twrp and then use this installer in twrp??
[OnePlus 8 / 8 Pro & 8T Cross Device Development] TerminatedGA:
I believe you have to flash the installer using magisk. If you want to flash using TWRP then you have to flash the recovery without the installer.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] janitor9:
No i don`t know what to do at first....so confused after all readings. Basic question is how to root? Used patched images but broke my fp sensor and my device is at service now.

If i just boot twrp and install magisk there and thats it :confused:

Quick question, do we have a nandroid backup & restore in the new 'test' twrp ? I was poking at this on Sunday. It appears not ready yet...
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Revenant Ghost:
After using this recovery for a while, I've decided to wait for a more stable version of TWRP... if it ever happens. Or at least until nandroid backups are fully functional.

I had no choice but to MSM restore my phone to get it back into a working state, thanks to experimenting with custom kernels and other modifications causing stability issues. I even ended up in the dreaded "Qualcomm CrashDump Mode", at one point.

Good thing I had a valid persist.img backup handy to fix my fingerprint scanner, or I'll be sending my phone back for repairs... again.

Since I really need this phone as my daily driver: I'll just stick with stock kernel, stock recovery and xXx Magisk ROM, for now. Thank you.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] hawkstwelve:
I'm on T-Mobile OnePlus 8. Network unlocked thanks mobdeep (shout out!) and unlocked bootloader.

I booted the twrp.img from fastboot - all went fine. I was able to open TWRP, decrypt data, and flashed the installer. Flashed successfully. Rebooted system. When I went to reboot into recovery, it rebooted, flashed TWRP boot image for a brief second, then went black. It then went into the Qualcomm Crashdump Mode with "fatal execution (something I can't remember now)" on one line and "die" on the next line. I started to sweat at that point, fearing the worst. Luckily, I was able to hard boot back into fastboot and then rebooted to system and everything loaded fine. Now I'm nervous to try to boot back into TWRP as I don't want to get stuck in that crashdump mode.

Anyways, wanted to throw that out there for general knowledge.

[OnePlus 8 / 8 Pro & 8T Cross Device Development] Docomoco:
I have read through this whole thread but there is a lot of of information here, somewhat confusing.

I would appreciate a concise summary of how to go about installing TWRP on my soon to be arriving, China sourced, Oneplus Pro 8.

First I will flush a global ROM.

Then I wan to install TWRP.

Finally root the unit with Magisk.

I have done these many times on my Oneplus 5T but by reading this whole thread it seems it is more complicated now.

There is talk about active and passive slots and then there is an installer and the actual TWRP img.

Thanks.

New version working pretty good, but wonder if it might be possible to access USB Storage. Currently, all that can be done is to wipe it. No mounting or selecting it otherwise..
[OnePlus 8 / 8 Pro & 8T Cross Device Development] fKm:
OTG is working without problems here.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] gaww:
Not the same thing. When using TWRP, you can't select it as a storage location - only internal SD. Same with TWRP file management.

Currently, I backup on internal storage, close TWRP, and copy over to external storage with file manage apps.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] fKm:
My USB Stick is working even on TWRP but okay...
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Nekromantik:

I can mount it and choose it as backup location on latest version
[OnePlus 8 / 8 Pro & 8T Cross Device Development] cheribibi:

[OnePlus 8 / 8 Pro & 8T Cross Device Development] gaww:
I am using an adapter and SD card, so maybe that is the problem.

That was the problem. The adapter had slots for the micro SD card,, or a space for the non-micro full sized SD card. I put the micro into the full sized adapter card, plugged it in, and now it is mounted by TWRP.

To wipe system what do i do? Or its not called system anymore?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] cultofluna:
You're not wiping system on A/B devices..

If you want to clean flash a new ROM , wipe data
[OnePlus 8 / 8 Pro & 8T Cross Device Development] juancheco95:
I fully understand the a/b slots now, due to super partitioning . Android has really evolved in these past years, my last Android device was the htc one which was super simple when flashing roms.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Pedimento:
I read all the forum and unlocked bootlader and successfully rooted my OP8 pro using the All in One tool created by mauronofrio, thanks to him. I also did backup persist.img.

My previous phone was Oneplus 5 so sorry for noob questions.

I want to try new kernels but before that i want to backup boot.img.

Each time i want to make this kind of backup/restore things do i need to use fastboot boot recovery option in fastboot mode ?

Actually i am confused with flashing twrp to both A and B partitions since i am not familiar with them.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] cultofluna:
You can do it ( restore stock boot )on fastboot or via a kernel manager app (EXKM or FKM)
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Pedimento:
Thanks, do i need to Back-Up and restore both A and B boot.img files when needed?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] knpk13:
No, just the current active slot will suffice. And fastboot and the kernel manager apps always pull from the current active slot so you don't need to specify a slot.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Nekromantik:
looks like the version posted on carbon thread supports flashing ROMs and those changes should be added to this soon yay

[OnePlus 8 / 8 Pro & 8T Cross Device Development] rickysidhu_:
I used the Magisk installer provided by the creator of the xXx ROM.

Just went into recovery to wipe dalvik and I just kept booting back into TWRP.

Tried using MSM tool to restore but my device would only stay in EDL mode for a few seconds, then would go back to TWRP.

I had to run the command fastboot erase userdata and start from scratch to get a normal device working again.

I wonder what went wrong so I can avoid it in the future.

You can do that via TWRP in the wipe menu. There you can change the format.

I just downloaded the US OOS download. I am going to use the manual update install, but it states that the automatic install could be done with root and TWRP, which I have. Would that actually work ?

If I manually install, will it wipe TWRP like it did last time ?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] sting5566:
If you do the local update it will for sure replace twrp with stock recovery.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] gaww:
I thought of that also. The automatic would have to not include recovery, but would root survive ?

Also, I thought at one time some had complained about the automatic not working, but they may not have had TWRP which was needed.

Update - it says root will be removed, so it will be easier to manually update and preserve root, and then reflash TWRP with xXx's installation script.

How much is this twrp close to being stable?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Samuel Holland:
Hi, I was just wondering, when I installed the update I selected auto and selected the magisk zip. It rebooted to twrp installed the update but then just rebooted. I had to fastboot flash recovery and then root after in twrp.

Should I have booted to twrp manually, flashed the update, and then twrp & magisk?

Flashing twrp I know I seen about replacing the latest in the installer zip, but can't twrp flash the image also to one slot at a time?

I'm assuming also to replace the latest twrp in the installer zip, I would do that on Linux or windows right?

Anyway thanks to all making this possible and I figured I'd ask to see if anyone might have had the experience that I haven't experienced yet. I have been trying to follow everything but this was just some questions I came up with and found myself not being too sure of.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] vtec303:
Thats the thing my friend even if you flash the update manually in twrp and than flash twrp, atm twrp being an image file you select image and than "recovery" but it doesn't gets flashed on both slots and when you reboot recovery phone boots into oneplus recovery, at least that is my experience, the best thing is to flash update than boot into bootloader and flash twrp on both slots, boot back in twrp flash magisk, cheers

[OnePlus 8 / 8 Pro & 8T Cross Device Development] Paulenski:
It's stable if you're just looking to flash full OTA with Magisk. The backup functionality is broken as mentioned but if you just want OOS updates and have Magisk for root access, it works great. I recommend following the typical update method in recovery: uninstalling Magisk with zip, flash Full OTA, re-flash magisk + modules & TWRP recovery img, switch slot (Reboot > Select inactive slot), reboot recovery to enter inactive slot, repeat previous steps of flashing each part. I would not follow other suggestions of installing OTA using the System Update Tool (local upgrade option) then re-installing Magisk via magiskmanager, it just bootloops. It sounds easier but it definitely did not work for me and lost TWRP in the process.
