[OnePlus 8 Pro Questions & Answers] Guitarfreak26:
I'm trying to work out what's happened as well.

Did we definitely have EU models? I honestly can't remember checking the build number before all of this.

Does the international one have the CE logo on the back ?
[OnePlus 8 Pro Questions & Answers] Guitarfreak26:
Can't be sure if the IMG is flashing right in the app.

Does anyone know how to flash via the dd command ?
[OnePlus 8 Pro Questions & Answers] Nekromantik:
did you use fastboot flash persist persist.img before?

---------- Post added at 04:39 PM ---------- Previous post was at 04:36 PM ----------

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

but you need to convert the sparse img to raw img via https://xdaforums.com/general/general/dev-simg2img-windows-t3156459
[OnePlus 8 Pro Questions & Answers] Guitarfreak26:
Thanks I will try this.

Fastboot doesn’t work cus it says critical flashing locked
[OnePlus 8 Pro Questions & Answers] s3axel:
Maybe try "fastboot reboot fastboot" before, it will load something looking like the recovery but being another Fastboot instead...

Edit: forget it, doesn't work...
[OnePlus 8 Pro Questions & Answers] Nekromantik:
after you used unbrick tool make sure you ensured bootloader is still unlocked
[OnePlus 8 Pro Questions & Answers] cultofluna:
After you restore the persist img partition

You have to flash your ROM again..

To have back sensors
[OnePlus 8 Pro Questions & Answers] Guitarfreak26:
I’m now in Qualcomm Dump mode. Goes back to that even after a flash with MSM.

Maybe it’s finally bricked :/ lol
[OnePlus 8 Pro Questions & Answers] cultofluna:
Have you flashed the persist img on fastboot

fastboot flash persist persist_name_xxxx.img
[OnePlus 8 Pro Questions & Answers] Guitarfreak26:
Gonna try mess around again now. Problem is MSM locks the bootloader so then u cant flash. Unlocking it says Qualcomm dump as well lol.

Gonna try again now
[OnePlus 8 Pro Questions & Answers] s3axel:
I wish you good luck... What went wrong?

---------- Post added at 08:03 PM ---------- Previous post was at 08:01 PM ----------

I also tried, with bootloader unlocked - says that flashing critical partitions is not allowed...

Writing the partition via the tool doesn't seem to work either...
[OnePlus 8 Pro Questions & Answers] Guitarfreak26:
Yeah think im done now.

It wont boot into the from anymore just Qualcomm crash dump. Following msm tool the bootloader is locked and can't unlock without the oem unlock option ticked. So seems like a RMA. Never had issues like this with a OP before, think ill just ask for a refund
[OnePlus 8 Pro Questions & Answers] cultofluna:
That sucks ...
[OnePlus 8 Pro Questions & Answers] Guitarfreak26:
Still didn't work out what caused the fingerprint issue either.

Definitely weird with all the others that have the same issue. On my previous OP phones, MSM tool always fixed everything. Now it seems it doesn't touch the partions.
[OnePlus 8 Pro Questions & Answers] cultofluna:
Other users probably have flashed the wrong ROM..or boot img

Like been in EU and installing global ...

Maybe you've flashed the wrong boot img

Definitely MSM on previous OnePlus devices fixes everything
[OnePlus 8 Pro Questions & Answers] Nekromantik:
MSMTool should be able to un brick all soft bricks.

If you use the tool you cant boot back into android?

are you sure you are fashing the correct version.
[OnePlus 8 Pro Questions & Answers] cultofluna:
I still think you have to contact mauronofrio..

He will help you...
[OnePlus 8 Pro Questions & Answers] Nekromantik:
it deffo looks like he flashed the wrong version initially so lost fingerprint.

in MSMtool thread it says

"Warning:

It is advised to take backup of /persist partition before crossflashing (eg going from International to Indian build) as fingerprint reader may give an error related to enrollment issue"

Alot of people been flashing wrong boot images etc
[OnePlus 8 Pro Questions & Answers] cultofluna:
How we can backup / persist partition?
[OnePlus 8 Pro Questions & Answers] Nekromantik:
dd if=/dev/block/bootdevice/by-name/persist of=/sdcard/persist.img
[OnePlus 8 Pro Questions & Answers] Guitarfreak26:
Yeah even after MSMtool completes the flash. The phone goes to the 1+ logo, black screen then qualcomm crash dump. This is after the EU flash.

Initially this occured after i had flashed the stock europe boot img (no magisk) and factory reset. I hadnt touched the MSMtool until the fingerprint error occured.

Previously the MSM tool would fix everything. I flashed the persist img before making it a raw img. I think thats ruined it.

MSM isnt touching the persist partion for some reason
[OnePlus 8 Pro Questions & Answers] Nekromantik:
MSMTool should fix that too. Its meant to fix softbricks which yours is.

Talk to the poster who made the msmtool thread or mauronofrio
[OnePlus 8 Pro Questions & Answers] Guitarfreak26:
I think it did up until the 7T from what ive read?

Cus theoretically if it replaced the persist partion the MSM would fix the fingerprint issue. When i spoke to the OP on the MSM tool he advised it would either be DD a persist image or RMA.
[OnePlus 8 Pro Questions & Answers] cultofluna:
Contact mauronofrio ..

He will help you
[OnePlus 8 Pro Questions & Answers] Guitarfreak26:
Just messaged him. Pretty sure its a brick though sadly.
[OnePlus 8 Pro Questions & Answers] Guitarfreak26:
https://ibb.co/Km7Npq4

Image wouldnt host, but thats whats showing.
[OnePlus 8 Pro Questions & Answers] cultofluna:
So you have to go for RMA?...

I thought that OP devices are impossible to brick..
[OnePlus 8 Pro Questions & Answers] Guitarfreak26:
So did i.. Till this one. Lol.

i think its cus we cant get TWRP anymore either. Dont think the 7T ever got TWRP
[OnePlus 8 Pro Questions & Answers] Nekromantik:
Incorrect 7T does have TWRP.

https://xdaforums.com/oneplus-7t/development/recovery-unofficial-twrp-recovery-t3976961

OP7 Pro/7T pro does not have official ones but we do have a dev who makes them for our phones. The official 7 Pro ones were stopped being maintained and thus for Android 10 it was unofficial only.

and MSMTool is for all devices not up to 7T. This is brand new phone it will take time for devs to find out internals.

Can you access ADB from bootloader or recovery?
[OnePlus 8 Pro Questions & Answers] cultofluna:
Yep. ..7T/7Tpro still no twrp

But normally by flashing the persist img on fastboot , you should be ok...

What happened?
[OnePlus 8 Pro Questions & Answers] Nekromantik:
Wrong again

https://xdaforums.com/oneplus-7t/development/recovery-unofficial-twrp-recovery-t3976961
[OnePlus 8 Pro Questions & Answers] Guitarfreak26:
ADB devices doesnt show in fastboot or recovery. However, I can get to recovery and fastboot but thats it.

And BL is now locked due to MSM tool
[OnePlus 8 Pro Questions & Answers] cultofluna:
Sorry but OP7tpro twrp is definitely not fully functional...

Is just an existing thread...

Nobody uses it...
[OnePlus 8 Pro Questions & Answers] dlads:
So what's the take away from this?

What caused the failure?

According to guitarfreak he didn't flag s different region so why did it happen?

[MENTION=1954600]guitarfreak[/MENTION] did you flash an older IMG for root? Then the subsequent flash of the MSM tool topped it off.
[OnePlus 8 Pro Questions & Answers] Guitarfreak26:
The fingerprint sensor issue was caused by flashing stock boot img then factory resetting. No idea why.

I don’t know why the boot img would touch the persist partion.

Only other thing I can think. If the phone was international and not Europe. And then he flashed the eu boot img incorrectly but it’s purchased from OP directly in UK
[OnePlus 8 Pro Questions & Answers] Nekromantik:
if phone is bought from a Euro shop it will be the Euro edition.

If its bought from China it will be the Chinese version

Indian as its own version

Rest are Global/international.
[OnePlus 8 Pro Questions & Answers] Guitarfreak26:
Yeah it’s a strange one, just don’t know what else to try other than RMA
[OnePlus 8 Pro Questions & Answers] zige:
Thats sad... I think im not gonna test myself to flash persist img yet... This is my only phone atm so cant mess it up to useless state.

Maybe i just need go to Oneplus service center and ask if they can fix it when im waiting. Or just return it and get new one etc. Though i would probably lost my Wireless Bullets 2 which i got with phone.
[OnePlus 8 Pro Questions & Answers] RayInkube:
Got the same bug, fingerprint is not working after use the second method on flashing modded boot.img for root.. tryied everything but nothing working.. so sad
[OnePlus 8 Pro Questions & Answers] DforDesign:
Anyone had luck with fixing it? When I try flashing everything stock it says flashing critical not allowed. I tried fastbood flashing unlock_critical but same story...
[OnePlus 8 Pro Questions & Answers] cultofluna:
You have the persist img?
[OnePlus 8 Pro Questions & Answers] zige:
Yup same for me. When using fastboot packs provided in here it gaves lot of "critical flash not allowed" messages. It finishes but wifi etc. are missing. With MSM tool i was able to get wifi etc. other missing things back but fp scanner didnt work. And someone asked if we were using same version which we originally had. I triple checked and all files i was using was for EU, like my device was EU version when bought.
[OnePlus 8 Pro Questions & Answers] s3axel:
Same here, too.

I'm still wondering what's happening here,though. I never flashed a different ROM, flashed Magisk from within ROM after having booted a magisk'ed Boot image... And the whole procedure worked fine once, the problem only occured after a factory reset.

Oh well, guess I have to wait for OP to sort it out....
[OnePlus 8 Pro Questions & Answers] cultofluna:
That sucks..

Hope that OnePlus address and fix the issue...asap..
[OnePlus 8 Pro Questions & Answers] zige:
Yup. For now i contacted my retailer and im trying to arrange RMA with this and asked if they could change it to new one.
[OnePlus 8 Pro Questions & Answers] Guitarfreak26:
Somethings really weird with so many people having the same issue.
[OnePlus 8 Pro Questions & Answers] DforDesign:
Yeah, [MENTION=2172904]Guitarfreak26[/MENTION] im not flashing for the fist time and this **** makes me feel dumb xD

Im going to try twrp I found on soe turkish forum...
[OnePlus 8 Pro Questions & Answers] Guitarfreak26:
My RMA is going in. I’ve asked for a refund for now then probably buy from amazon in the future to get easier support. Had the UPS label through now it’s gotta go to Poland
[OnePlus 8 Pro Questions & Answers] s3axel:
Same here, this is really strange... My feeling is that somehow on the way persist got corrupted, ending up in a dead end because also MSM does apparently not recover it.

My feeling is that the fingerprint issue is something different and basically a bug in OOS...
[OnePlus 8 Pro Questions & Answers] DforDesign:
I was able to boot with this twrp. Flashed persist.img, but something is wrong cause it says invalid argument when mounting

Also tried dd command with twrp terminal. If the persist file needs to be converted somehow please tell me how. I have access only to Mac OS.

[OnePlus 8 Pro Questions & Answers] Guitarfreak26:
Yeah one of the guys a few pages ago said it had to go from sparse to raw but it’s over my head lol.

I can’t even flash a twrp build now due to the locked boot loader lol
[OnePlus 8 Pro Questions & Answers] DforDesign:
im now stuck in qualcomm crashdump mode since it switches the bootloader to locked and im not able to boot the system.
[OnePlus 8 Pro Questions & Answers] Guitarfreak26:
That’s exactly what happened to me.

MSM doesn’t fix the partions either
[OnePlus 8 Pro Questions & Answers] Nekromantik:
http://newandroidbook.com/tools/imgtool.html

thats MAC version of the tool

you will also need to install ext4fuse

more info here https://medium.com/@chmodxx/extracting-android-factory-images-on-macos-cc61e45139d1
[OnePlus 8 Pro Questions & Answers] DforDesign:
did they tell you how much it will cost?
[OnePlus 8 Pro Questions & Answers] Guitarfreak26:
I’ve asked for return as I’m in the timeframe. They sent a UPS label. £2.40 for collection.

Of course, you were applying the latest OTA and it got stuck in that. As the boot loader is locked you haven’t been messing with it ;) lol
[OnePlus 8 Pro Questions & Answers] nathlynn22:
I didnt get charged for collection I dont think?
[OnePlus 8 Pro Questions & Answers] Guitarfreak26:
Mine was £2.40 unless I input some ups details that I didn’t have. It said give the cash to the driver lol
[OnePlus 8 Pro Questions & Answers] zige:
I just came from retailer shop and they immediately changed my phone to brand new version. Didnt even ask further information or tested the problem. Good luck for you case mate! :)
[OnePlus 8 Pro Questions & Answers] Guitarfreak26:
Glad you got it sorted. Mines just been picked up from UPS. I’ve opted for a refund and I will buy one when it’s back in stock at Amazon. Don’t want the hassle of going to Poland again if I get a bad screen or the fingerprint issue
[OnePlus 8 Pro Questions & Answers] zige:
Good choice! Thats reason why i didnt want to get from Oneplus website so i can deal possible RMA's faster. Its only 25 kilometers to retailer where i got this.

Regarding of bad screen this one has also same thing. But its like lottery to get perfect one. I will wait software update as they promised it can be done with software. Samsung S20 ultra had same thing and it got fixed with software. I think its something to do with how Oneplus change brightness as i noticed big difference with changing style.

---------- Post added at 11:04 ---------- Previous post was at 10:42 ----------

Hey buddy! I just got message from Oneplus Exclusive Service Center here in Finland. They said that Oneplus developers has confirmed that FP error is definetely software bug which will be fixed in next update which is coming "some days or in a week".
[OnePlus 8 Pro Questions & Answers] Guitarfreak26:
Crap wish I had waited lol
[OnePlus 8 Pro Questions & Answers] devsx:
Is there any update on this issue? Cause I still have it, OP says open RMA, but I dont' want to..
[OnePlus 8 Pro Questions & Answers] Nekromantik:
People think if you have the FP issue you have no choice but to get replacement as the OTA will only fix it from happening.

So next time you factory reset or re lock bootloader it wont break but if its already broken it wont fix it.

No idea when the OTA will be released as 10.5.9 did not mention fingerprint fix in the log
[OnePlus 8 Pro Questions & Answers] pyry666:
Have you had any black crush etc issues? Pm me I am also from Finland

---------- Post added at 01:01 AM ---------- Previous post was at 12:59 AM ----------

As it didt not mention any display fixes..My green tint is almost gone. Black crush is still here..
[OnePlus 8 Pro Questions & Answers] wizzman:
You need your persist.img backup it's the only way... otherwise it's RMA....
[OnePlus 8 Pro Questions & Answers] inteks:
i restored my on backup but result in brick!!!! it seem oos version depented... you should make a new backup after OTA update.
[OnePlus 8 Pro Questions & Answers] pyry666:
Well thats good to know and it doesnt be thats much trouble anyway. BUT I still havent got any solid proof witch causes fp to corrupt (except some magisk vanary version)
[OnePlus 8 Pro Questions & Answers] byAidan:
Basically there are two ways that the fingerprint could break.

Magisk

- Temporary FP issue that was fixed by updating Magisk (only one nightly version was affected). This isn't an issue anymore. If you have updated Magisk and your FP is still broken then you have the second issue mentioned below.

Factory resetting/Re-locking bootloader etc

can potentially mess up your persist partition - Permanently breaks FP (Unless you have a back up of your own Persist partition).

Hopefully OnePlus can stop it from happening in future but they can't fix your FP via an OTA if it's already broken.
[OnePlus 8 Pro Questions & Answers] frogees:
I myself experienced the lost of of FP after relocking my bootloader. Worth mentioning that Amazone simply replaced the unit after a 3 mins chat yesterday at 4 pm and the replacement unit arrived today.
[OnePlus 8 Pro Questions & Answers] pyry666:
Again not to be rude or anything. Those things I allready knew.. I was asking what causes this. Not what steps but what in persist.img. I cant seem to get straight answer even from oneplus..
[OnePlus 8 Pro Questions & Answers] byAidan:
Something appears to break the trust/encryption between the OS and the fingerprint sensor.

The persist partition most likely contains a security key for the encryption which gets incorrectly wiped/corrupted when re-locking the bootloader.

Restoring your own backup brings back this key (which is why other people's persist files don't work as the key isn't correct).

If you don't have the backup, OnePlus needs to re-calibrate/re-generate the key between the OS and fingerprint sensor.

Think of it as similar to SSL certificates on websites, the private/public keys need to link up or else you get a security error.

Hope it helps!
[OnePlus 8 Pro Questions & Answers] superior888:
i succesfully fixed my fingerprint with persist.img but after locking bootloader again it didn't work. Any way around that?
[OnePlus 8 Pro Questions & Answers] byAidan:
DId you remove any saved fingerprints before re-locking the bootloader? It would be interesting to see if that works.
[OnePlus 8 Pro Questions & Answers] superior888:
hmm interesting. i don't remember but does it wipe when locking? i'll try
[OnePlus 8 Pro Questions & Answers] byAidan:
Yes you're right, it should wipe when you lock but maybe that's what is causing the issue (Like if you format data on a device in TWRP without removing your PIN/Google Account it triggers Factory Reset Protection).

I would try:

-Unlock bootloader again

-Restore working persist

-Add fingerprint

-Remove fingerprint and any other security/Google account

-Re-lock bootloader and see if FP works
[OnePlus 8 Pro Questions & Answers] superior888:
It didn't work. This is actually wierd. Why would it break when locking the bootloader?
[OnePlus 8 Pro Questions & Answers] cultofluna:
Now you can only stay unlocked to have a working FP..

And wait until oneplus pushes a fix through OTA..

Issue is that relocking the bootloader messes up the FP calibration file..

If FP is not working, you have only two options:

1. Restore a working persist image file

2. Have OnePlus recalibrate it

Have you tried this?

[GUIDE] Fix PERSIST.IMG Loss Of Finger Print Sensor

New video guide below VIDEO GUIDE 1. *VERY IMPORTANT* We need to back up your broken persist.img and store it in a safe place. PC preferred. We will need this later. Do not leave the backup on the device as the next step will wipe the device...

[OnePlus 8 Pro Questions & Answers] Alfredosp:
Hi dear, i have not an backup to chance the internal files. But thanks
[OnePlus 8 Pro Questions & Answers] d3viou5:
I think from reading it you can back up the non-functioning version and effectively repair it, unless you've lost it entirely?
[OnePlus 8 Pro Questions & Answers] Alfredosp:
I wrote about each other without having backed up, there is no data from the first one.
[Xiaomi Mi CC9 / Mi 9 Lite Questions & Answers] Diabolik2770:
i bought a mi 9 lite and it came with the russian rom.

I wanted to unlock the bootloader and install the official globlal ROM with mi flash. can i lock the bootloader again with me flash when i install an official global rom?

or

is there a guide to install a global rom without unlocking the bootloader? and without using tools?
[Xiaomi Mi CC9 / Mi 9 Lite Questions & Answers] Reentry310:
You need to first unlock your bootloader in order to fastboot flash the global rom (using MiFlash). After that in the MiFlash tool there is an option to "Flash all and lock" which will lock your bootloader again. Unfortunately there is not a way of doing it to my knowledge without unlocking your bootloader.

Here's the official guide here: https://c.mi.com/oc/miuidownload/detail?guide=2
[Xiaomi Mi CC9 / Mi 9 Lite Questions & Answers] .M.D.:
Never, ever re-lock your bootloader as this will result in a hard brick that can only be resolved with EDL/authorized account!
[Xiaomi Mi CC9 / Mi 9 Lite Questions & Answers] TheMalachite:
Your post is in the wrong section, this should be in guide, news, discussion
[Xiaomi Mi CC9 / Mi 9 Lite Questions & Answers] Reentry310:
Not to my knowledge. I have done it before with my device. Sure if you want to use custom roms/recoveries you will need to unlock your bootloader again which you can do if you are using an authorised account. However, if you are really worried about this happening, you might as well just keep your bootloader unlocked.
[Xiaomi Mi CC9 / Mi 9 Lite Questions & Answers] k4sh44:
I bought a mi cc9 lite that came with a russian rom.

Before i could unlock my device, i was able to flash a global rom with a non official tool which name i can't remember.

Global rom was the only one i was able to flash. So yes it's possible.
[Xiaomi Mi CC9 / Mi 9 Lite Questions & Answers] MaDMaxiBo:

[Touch Diamond, MDA Compact IV General] Riel:
Hello,

Does anyone know a way not only to backup PIM, but also Email settings and COnnection/VPN settings/Exchangeserver settings?

It is quite annoying jotting them down everytime I try a new rom.

No tools for this? Must be some reg keys only aren't they?
[Touch Diamond, MDA Compact IV General] Furbious:
Why not back the registry up using sprite or a reg tool?
[Touch Diamond, MDA Compact IV General] Riel:
New Roms have other Registry settings I guess?
[Touch Diamond, MDA Compact IV General] darthbane2k:
This is what I would like to know too
[Touch Diamond, MDA Compact IV General] ryujakk:
I doubt it's in the registry: I searched for my account name and it wasn't found. Try looking into the "Documents and Settings" folder; that seems promising to me!
[Touch Diamond, MDA Compact IV General] Furbious:
Ok, since you dont want to do the work, try exporting these hives:

wifi conn - HKCU\comm\EAPOL\Config

Sounds/notifications - HKCU\control panel\notifications

Exchange activesync settings - HKLM\system\activesync

To start off with.

Most of those keys should be fairly standard, roms should only change HTC and other software/hardware specific entries for tweaks.
[Touch Diamond, MDA Compact IV General] laser21:
This would really help! I have no idea where to look for those settings... Also I would like to save the settings about my favourites (people shoving up in manila) so that I dont have to add them every time I reflash. Thanks
