why don't you update your kernel from 2.2 to 2.3? And I think 4.1.2rom is not fluency for our defy . if you have the kernel 2.3,you may update to kitcat~
update your phone . you need pay attention to the following list .
1.Use the software named RSD,the file is sbf ,sbf will change your bl,so, you need to know what's your phone bl;
2.you need to now what's your defy's lens,it's red or green;
3.you need a rom which is .zip some rom don't need to think about the kernel but someone discriminate.
o it's the first time I reply in English,if I say something wrong or you can't understand.please forgive it . haha I have a bad English. and I think I need someone to fix my grammer error。and when i speek english I don't know what I said above。。。

THX for the reply

An advice, make Full Backup of current ROM/Firmware before doing anything with device you are willing/thinking to try.
I'm using Huawei Ascend y511. so can't do that, but i believe "CN" stands for Chinese and "EN" sure for English. regarding recovery language, for me i get two different modes, recovery and factory setting i believe. Stock recovery for my mobile is in English and the other is Chinese. But, in case you get chinese recovery, i think it can be replaced with "Custom Recovery (English)".
Once Stock/Custom ROM is installed/flashed, you sure can change language option to English or Chinese as mentioned about ROM languages (Not for recovery).
Point is that; once ROM is installed/flashed & you are satisfied with it and you also got backup of current Kitkat ROM and you find recovery is in CN. You can restore ROM to Kitkat or in case you don't care about warranty and can flash/install Custom recovery(English language) without going into CN recovery. then i think it shouldn't be a problem.

this rom work fine with my device

Flash Mozilla OS on Android.

Hey guys can anyone please tell me hour we can flash Mozilla os on an android device. I went through the procedure on their official website but couldn't understand. Please let me know the procedure.

I've never done it, so I'm no expert, but I'm sure it depends heavily on the exact model of Android device you have.

Yup the official website has methods only for nexus series. Can't there be some way to flash it on every android device?

is it possible?
Hey is it possible???
are you talking about multiboot???

Still haven't figured it out. Actually I need custom ROM based on RK3288 for tablet but I cannot find the original files. The current build number I have is rk3288-userdebug Android 6.0.1 MXC89K (pixel C-based?). So it seems that I need to download the source from RK and not Android repo right? It is a variation of it?

Oneplus 5 android 9.0.9 to stock rom

Hi there,
I was wondering if it is possible to go back to the original stock rom from OnePlus 5.
I checked the OnePlus website, but they don't provide the stock rom no more.
I watched some YT videos and stuff, and most are about rolling back to 8.0
My phone is not rooted or whatsoever, so i am also looking for a root free rollback.
Thanks !

Hey, thanks for the post but this post goes for updating the OP5 To android 9.0.
I'm looking for a way to rollback from 9.0 to stock rom android or android 7.
I found this : https://forum.xda-developers.com/oneplus-5/how-to/oneplus-5-mirrors-official-oxygen-os-t3628190 I downloaded the 4.5.2 one.
I just wonder if its safe to just put the rom to my phone and push the update while i am on android 9.0 with locked bootload and no root. I do not like to break my phone
Also, i am kinda a noob at this point. So please not to much "geek talk" , thanks

I don't think it's possible cause it's a android version downgrade.
