about easy downgrade [Solved]
 

Where do I find the files for easy downgrade?
I understand that it works with some files that should be found in the respective support, however I have reviewed and can not find anything for the vtr-l09

Not need any special file bro you need download suitable board firmware and you will get this After select xml : New option named :. 'Easy downgrade'

Note! If write nvme and oeminfo partitions in Bord Firmware mode, to your device will record default Imei, SN and other calibration settings, the original IMEI, SN and calibration will be corrupted and you will have to restore through another mode. Press 'Easy downgrade' button if you want to write without erasing the security and NV Press 'Full Repair' button if you want to write all partitions include NV
Selected 'Full Repair' mode

Could you show me an image? I don't find that option

Some help? I try to understand the new function

I tried a p20 lite, a psmart and a P10 and I can't find this option, what am I doing wrong?

You can find that option on Upadte OEMINFO tab, check Updae Bootloader, after press Update button!

And need select board firmware or not needed

Yes, You need to select board firmware

But Easy downgrade must be in same flash tab with flash board firmware or add New profile with other profiles in board firm

We'll make a video instructions where we'll show You whole process

investigating I find out that the easy downgrade function is enabled when using .obf files, I do not understand why they told me that I do not need any special files generating more confusion, in the Path: / Huawei / Huawei Board Firmware / Huawei Compatible Board firmwares / I see some Few models, what is the list of compatible models and where do I get the respective .obf files?
The description of the update mentions that the easy downgrade is for hisilicon devices (such as p smart) but the .obf files that include this function are qualcomm
I'm trying to understand the easy downgrade but nobody helps me

How is it possible to make easy downgrade on hisilicon devices and what models are compatible? the tutorial on its YT channel shows an LDN-AL30 which is a Quacomm device

For EasyDowngrade operation, You can use any board firmware which is compatible with device model. If board firmware was selected, there are some partitions, which erase SN and IMEI. If You will press Easy Downgrade button, then these paritions will not be written and all important paritions will be saved (SN and IMEI).

in version 1.1.2 it didn't work, in the new version it works for me
