Canadian Wind GR5w bootloop

[seedai_murukku]

Hello all. I have a GR5W phone, which I think is specific to wind (freedom) mobile in Canada. I have unlocked the bootloader and managed to install TWRP. But none of the ROMs meant for the 5X work on this phone (I've tried Lineage, CM 13, Slim). In my enthusiasm, I forgot to backup and now I don't have a stock ROM to go back to. Huawei doesn't have any stock firmware on their website. What are my options? I did try using the dload method to update to other firmware, but all result in boot loops. Please help!

Which model do you have? It would say that on the box -- do a search for the specific model (eg: KIW-L24, KII-L05, KII-L21, etc) firmware for your phone.

Thanks for your reply. This is a friend's phone. He threw the box out. All I know is the model number is H1621 and it is mentioned as GR5W in huawei's website. Its FCC id is QIS-KIW-A1. I'm going to try flashing a TWRP backup from another thread this weekend. Hopefully that would work.

So, that didn't work. I also found out the phone is called KIWI-A1 (gr5w h1621). Huawei has published the kernel code for this. I don't think this model is supported by any of the Huawei 5x roms. Can I request the lineage team to add this model?

Boot-loopin' and Backup is Bust

Hi seedai_murukku,
Did you have any luck restoring any ROM to your KIW-A1?
I've found other KIW ROMs but they all result in the same boot loop that you described. Thanks.

Hey Guilo,
Still no luck. I tried to compile a custom boot.img from the source. Got stuck with a few warnings and gave up. I might try fixing and re-compiling soon.
