[Huawei P20 Guides, News, & Discussion] blufreak:
This is simply a collection of information with some blanks filled in to allow those not as well versed in huawei/ADB as myself to rebrand. After 4 days of agony with Funkyhuawei and very little info i managed to resolve the issue myself. Primarilly, rebranding from pie on their toolkit would not work and i did not feel comfortable rebranding the more involved ways explained on here here.

You will need a membership to FH and credits. Also to have selected the same version eg 8.0.0.159 for the TARGET region. for me, i was c782 but rebranding to c432 so selected clt-l09c432 8.0.0.159

It is written with the intention of using FHRebrandTool2, as this one allows you to remain as CLT-L09 if that is your model, not force a switch to L29 even without dual sim

First, obviously, if you cant/havent unlcked FRP and bootloader, stop reading now. You're process is finished lol

Second, remove all security pins and fingerprints (developer options>require to be unlocked>off)

If you are on pie, use this incredibly simple automated script setup from [MENTION=7356302]Androlark[/MENTION] thank you my friend for this as you saved me here https://r.tapatalk.com/shareLink?ur...share_tid=3841687&share_fid=3793&share_type=t this is necessary as rebrandtool does not operate correctly with android 9 but fh instructions and even FH help are unclear on

For the correct software, download your latest android 8 version from Firmware Finder, taking note of the changelog, the flashing requires older update version with THREE folders, the giveaway is the changelog says "this will rollback your device to emui8" (dont rollback using Hisuite, as it itself advises not to if device unlocked. When selecting download in FF you may be presented with a list of many folders, most with the same name, simply click one of each name (update, public and cltxxxxxhw) transfer these to your phone after checking "check availability by imei" and doublechecking you have selected the correct region (C782,c432 etc)

Before flashing, to save panic, READ "AFTER FLASH INSTRUCTIONS" in flashy folder of extracted flashtool downloaded from above.

Follow post and flash.bat instructions and its all automated.

Factory Reset as advised when complete

Wahey you're back on old faithful Oreo and still device unlocked

Now startup device, complete basic setup to access menu, ensure adb AND allow adb during charge mode are on (this helps stop adb turning back off at restart in some cases) ensure to forget any wifi connection you used during setup

Back to fastboot (device off, hold power down,connect cable to computer) once loaded run FHRebrandTool2 again, being careful if you use manual entry to assign new model and region

Once complete and you restart you will keep getting connect usb to continue rebrand dont panic, hold power until shutdown then hold volume down and connect usb to computer again, you will get Erecovery. Select Install latest package and use the FunkyHuawei instruction from here, EG change DNS on router or use a computer as a hotspot to install new region software and wait.........wait.........wait.........funkyhuaweis carrier pidgeons are a bit slow

Rebranded and update back to pie and enjoy the precious security updates
