[Discussion] issues faced while moving to stock from custom ROMs. - Honor View 10 Guides, News, & Discussion

Hi,
just to share my experience on the problem I faced while moving to stock ( I know these are my mistakes and anyone can do this so wanted to share just to save other new users)
I was on one of the custom ROM yesterday but due to lag in camera and slight other bugs (or say due to my requirement), I wanted to go back to stock. I had all the files, TWRP backup but as TWRP doesnt work on Android 8.1 for V10 (except BKL-L04), it was much complicated.
While flashing my stock system.img, I didnt realize that I am on magisk and patched_boot.img rather stock (that was my mistake) and just flashed my system.img and then factory reset in stock recovery. My phone booted fine but then no service for SIM cards, checked in about phone and found that I have lost my IMEI. (no other bugs). My bootloader is still unlocked but FRP lock (I did factory reset remember and I had the google account on earlier custom ROM which I did not delete)..
If you come across this situation, you can boot few times but this will remain the same and factory reset will not help. I was unable to flash TWRP to restore my stock backup (android 8.0, TWRP works on this, right) as my FRP was locked. Even enabled google account and factory reset all but no luck. Then, I made another mistake of relocking the bootloader. Once re-locked, It was in bootloop and only fastboot and erecovery was accessible.
I had no other option but to only download the full file in erecovery and boot. It will be a different file which we do not get on firmware finder, in my case, it was BKL-L09C432B160- FULL file. It took me 4 hours to download the 3GB full file (was in office and was unable to connect to office Wi-Fi, no hotspot issue on iOS12 beta, no 4GB SD card or data card which I normally carry with in bag so burrowed a data card and used my sim and downloaded the 3GB file in 4 hours). Once file was downloaded and flashed, all were fine with IMEI and everything stock.
Just wanted to share this experience so that any other noob or new user do not repeat this and get into all these trouble ( I knew that I will be able to revive anyhow as I am familiar with Huawei/honor phones but it may not be the case all the time with you- its just we need patience with this).
You can share your experience if you come across such so that it will be helpful for others.
I will create a guide as well to get back to stock ROM from custom ROM based on my experience (will skip the dload method as it is already covered and I have not tested that on EMUI 8 - have done it more than 100 times on EMUI 3,4,5) .
Thanks for reading.

I don't think you can download full package from erecovery for Indian model.. it gave me some kind of failure error whenever I tried to download

Im curious how u lost IMEI and FRP lock? I flash couple times system.img and then factory reset in stock recovery without issues. Google account doesnt lock FRP no different if u signed in account or not. It is related to OEM in Developer section. I never delete my account, (when I sell my View10 I also dont delete my account just make FR and another person sign in and have FRP unlocked). Sometimes after flashing/Factory reset switch OEM to disabled

I did flash system.img on magisk ramdisk that may be the issue here for imei lost or may be i was on b160 before RR but flashed b130 image, anything. When downloaded b160-full in erecovery, all fixed.

If firmware is not available then possibly the error. But this should have it and error may be due to anything else corrupted, just a thought

Nope. Via erecovery, it automatically downloals the latest one

Interesting, just only Chines models was able install/download fw over erecovery. This is new! Huawei make some changes I think

Nope. I ahd the same behavior on my BLN-L22 Honor 6X. Initially it was China variant but post debranding, It was BLN-L22 and I was able to download the firmware via erecovery. Thats the purpose of erecovery, rescue tool

I never got updates on my Honor 5C in 2 years. Yesterday afetr trying for 12-14 hours of all trial, I was able to update to Nougat and 3-4 OTA updates together. It was tedious task.

No thats not true. As far as i seen, official twrp support Android 8.1 and that's for L04 only. But do support other devices with Android 8.
Openkirin ROMs does not support twrp. Which ROM are you trying

Oeminfo can be backed up in twrp or manually copy the file and custom bin under /data to be backed up manually.
