[Realme 8] HowWof:
Do not flash this if you have a phone bought in Poland phone will be bricked.

This is for some reason brave region global system does not work.

Interestingly the polish service has an account for free software flashing so my device was repaired but i heard that in other countries realme is replacing motherboards
[Realme 8] MP3Martin:
Worked for me in Czech Republic (next to Poland)
[Realme 8] safelock1:
hello,

I have relame 8 (RMX3085 ). I want rooted and crash phone.

First I have error number: 0x99256658 . In internet I find information is problem with partition oppo_custom

Where I make download copy of this partition on realme 8?

I'm find on internet else oppo_custom partition wnd write to phone (error not show and phone start logo realme and next black screen).
[Realme 8] Tony Stark:
What things you did before explain briefly. Did you wipe or modified any partition?

And where do you get that problem in sp flash tool or mtk client?
[Realme 8] safelock1:
Unfortunately, but I wiped everything (I tried many recovery options, tried to upload all partitions from the official rom (after extraction).

Currently I have upload access using mtk client and sp flash tool (with unlock).

I think the best option would be to fully clone partyji images using mtk client (from Linux).

To do this I need to have all the files (including oppo_custom) currently overwritten
[Realme 8] Tony Stark:
From where you wiped all partitions? Sp flash tool?
[Realme 8] safelock1:
I didn't wipe all partitions just did an upgrade with sp flash. I got an error about boot not unlocking.

Then, after starting the phone, it was: the current image (boot / recovery) has be destroyed.

Then I tried to upload the original software found on the internet. After this attempt, information about the incomplete installation appeared on the phone screen with the error code: 0x99256658. I read on the internet that oppo_custom partition was damaged. I found some oppo_custom file on the internet and the error errora 0x99256658 disappeared but the phone was restarting. I found another oppo_custom but this time the phone seems to start but the screen is black. That's why I'm looking for a verified file from oppo_custom for realme8 or preferably a dump of all partitions from a running android on realme 8
[Realme 8] Tony Stark:
Many users here ask someone if someone give you that partition.
[Realme 8] safelock1:
Still looking for an oppo_custom partition.
[Realme 8] dfahren:
Maybe I can give you an explanation for this weird, but normal behavior.

The reason for your phone showing boot image is corrupt is that you flashed an EMPTY vbmeta.img file. However what you need is your ORIGINAL vbmeta.bin partition with verification and dm-verity being disabled. So that's a completely different approach! Such a vmeta.bin partition is typically created when you issue the command

But that is not possible with Realme 8 because Realme saved themselves from implementing a fastboot deamon, which tuns out to be tough luck for us.

So whenever your phone has a firmware with a version >A20, this means you have an enforced Android Verified Boot (AVB) in place which checks to see if either boot or recovery or both partitions have been tampered with. To this end, this mechanism makes use of the contents in vbmeta partition. What makes things even uglier is that partition vbmeta is cryptographically signed. So once you alter even a tiny bit in this partition, your whole boot process WILL fail. Unlocking bootloader does not help in this respect, it only guarantees an appropriate MTK download agent is allowed to write to flash memory.

What can we do (as others have already pointed out, so credits to them)?

You could flash an old LittleKernel (LK) partition that has been altered to not do AVB correctly. If you also need an old preloader, is unknown to me but may be needed. The verification process in LK would simply detect an empty vbmeta partition and be forced to think full AVB is not necessary and boot regularly from either boot or recovery partition. This solution seems to be the only way out of this misery as of Mar. 2022. We keep all our fingers crossed that this does not remain the only viable solution...

You need a tool that mimics the works of fastboot. This would be a tool that's capable of disabling both verification and dm-verity for a given vbmeta.bin file so that your are able to write an altered vbmeta.bin file to vbmeta partition with 'mtkclient', for example. I'm not aware of such a tool, but if anybody out there has come across of something like that, I would be eager to hear about it!

That's just my two cents.
[Realme 8] Vo0zie:
I have a problem with the bypass tool, everything went fine until step no. 7

Was trying to solve it by myself 'cause I don't like to take other people's time but still, I've got the same error.

I've bought this phone already bricked, it vibrates, turns on, stays on the logo, and reset after a few attempts it's trying to go into recovery mode but without luck and resets again. Maybe there is just no hope for this one.
[Realme 8] Hcck:
Tested and working

But one needs to format data from stock recovery if boot loops after flashing .
[Realme 8] Hcck:
Can you upload c.06 decrypt firmware
[Realme 8] Hcck:
Can you upload c.06 decrypted firmware as I think it is the latest realme ui 3.0 build
[Realme 8] Hcck:
Can you upload decrypted version of c.06 rom
[Realme 8] xaavgar:
Hello! Could you tell me if this method works to downgrade to Android 11 version of the Android 12 beta?

I'm in the beta but it's very unstable.
[Realme 8] Hcck:
Yes definitely It will work
[Realme 8] Tony Stark:
Not possible, because c.06 not available on realme website
[Realme 8] Hcck:
Alright but please upload once it's available as I want to clean flash it
[Realme 8] Danick8989:
Does this need an unlocked bootloader? When I press Download on SP Flash Tool nothing happens. Checking on task manager the program isn't using any % of disk or cpu

EDIT: I left it for a minute and it shows this error:

[Realme 8] Hcck:
Kindly install python, pip and run mtk Bypass tool Brom.bat before using sp flash tool
[Realme 8] ultrasound1991:
Hi, is it possible to use python mtk to get a dump of the userdata partition, then mounting the partition or extracting the files on PC? I have not used the lock screen so my internal data should be already decrypted.
[Realme 8] HowWof:
I don't think it's possible and the data should be encrypted anyway
[Realme 8] ultrasound1991:
Does the phone warranty will be void once the brom.bat ends its work?
[Realme 8] HowWof:
The warranty will be valid.

If you want to return the phone to the service, lock the bootloader and say that it is after the update.

They will load original system and after problem data will be lost
[Realme 8] Tony Stark:
Nope the warranty will not void.
[Realme 8] niki.rsb:
I have already written here or in a neighboring topic, but I still could not find out. has anyone successfully re-lock the bootloader? how to do this?
[Realme 8] HowWof:
python mtk da seccfg lock

python mtk reset

and disconnect usb cable to let the phone reboot.
[Realme 8] niki.rsb:
someone wrote that this command doesn't work, so I didn't try it. But maybe it was a mistake on his part. And does anyone know how I can get into EDL mode? my volume down button stopped working, so I have to put in a claim.
[Realme 8] Tony Stark:
There is no way to boot into Brom mode without using volume buttons
[Realme 8] niki.rsb:
Yes, that's true, but I've already done the brom mode and installation.I thought it would stay permanently. Do I have to do it over and over every time I install? When I needed to remove the error, I booted into edl mode and ran the python command mtk e metadata,userdata,md_udc. I was hoping that would work as well. Won't it work?

Then I found three ways to return to the repository here:

"There are three ways to return to the repository:

1. Using RFT (Realme Flashtool)

2. Using TWRP (use the latest version from the recovery section).

*Wipe>Data format> enter yes> format.

*Reboot>reboot into recovery

*Install> select .ozip> swipe to flash

*Reboot

Don't select disable-vbmeta or avb_patcher or something similar.

Recommended-

3. Use stock recovery.

From the system: - To flash using stock recovery, download and paste the .ozip file into the root directory of the repository and click on it in the realme file manager. This will start the flash in stock recovery.

From recovery: - Download and paste the .ozip file into the root directory of the repository and reboot into recovery.

Your language> Install from repository> enter password (only if you have one)> Phone/SD card and then select .ozip.

Any custom recovery.img/boot.img files should now be replaced with the stock ones.

After successfully flashing and booting the device into the stock rom, reboot the device into the boot loader."

Does any of this help me lock the bootloader?
[Realme 8] HowWof:
Realme flah tool requires an unlocked bootlader plus our phone is not supported

If you do not enter brom mode you will not lock the bootlader
[Realme 8] aymen.mesbahi:
Sir, i have two questions ... And i wish you could help..

1: How could i decrypt the russian (export version) into a decrypted version, is there ola ready file already?

2: However i try to Download the flash, nothing happens, like my phone doesn't accept it at all (i have installed all the driver, and i've followed all the steps).

Have a nice day,

Hi, I was trying to downgrade my realme 8 from Android 12 to 11, and I saw this realme community post (https://c.realme.com/in/post-details/1509097324549316608) and then I proceeded to downgrading. What I didn't realize was this this the rollback package for Indian version, while I am from Philippines. You said in this forum that you got firmware from realmefirware.com, and so I saw there the regional Philippines variant of realme 8 software, so when I extract the .ofp from there, will it work on SP Flash Tool? And also, when bypassing, will it unlock the bootloader? Thank you in advance for responding.
[Realme 8] aymen.mesbahi:
I have the same exact issue !
[Realme 8] aymen.mesbahi:
#HELP#

I DID EVERYTHING RIGHT BUT THE FIRMWARE ISN'T PASSING BY SP FLASH TOOL!
[Realme 8] Reqie:
Did you do bypass?

Did you updated to 12 android and want to anroid 11?

Did you check drivers?

Did you check options of connection?
[Realme 8] Reqie:
How about bootloader maybe not.

For .ofp files, need convert to SP Flash tool support. Easily just download a.24 from top of thread and flash device.
[Realme 8] aymen.mesbahi:
Yes, i did the bypass

I had android 12, and wanted 11 yes.

i have checked the drivers.

i was disconnecting my phone after the bypass (but i shouldn't)

now i flashed the phone, everything works properly thank you!

Hello everyone. I've got a problem after trying to flash my realme 8 according to this guide and now my phone is bricked. I have infinite black screen with white realme logo and "Recovery mode" text in the bottom of the screen.

I did everything accoding to the tutorial except step 11.

Could someone help me?

I cannot open stock recovery menu, but I've tried to wipe all data after flashing using

python mtk e metadata, userdata, md_udc

but it didn't help neither.

Thanks in advance.

After downgrading using one these roms will my phone count as rooted? I wanna use banking apps and not sure if they will work once rooted
[Realme 8] HowWof:
The phone will be unrooted.

However on a rooted phone you can use for example magisk hide and universal safe net fix to allow the banking app to work, some don't even check it.

Tried with another computer and it works now. I'm trying to flash any global android 11 roms. .22 or .26 only bootloops into recovery. Formatting in recovery doesn't help. Only boots up when I flash global .24 but it boots into the Indian .24 (for which I accidentally downgraded to previously and trying to switch form now as I need the NFC function on a daily basis) . Anyone had similar issue? Whenever I try to flash another rom, I reinstall drivers, python, etc. so I actually follow all the steps in the description.

Noticed that at step 10, it says unpick 2 of the list, but on the pictures a 3rd one is unpicked as well (md1img). Should that be picked or unpicked?
