Any more details? Whats working and whats not (oppo a57)

7

Please someone tell me how to fix the bootloop? I want to use this rom. Is it because of the persistent files or vendor file or what? How to fix? I will try some stuff. Please provide instructions. Also, what’s not working on this rom??

8

Did you read the instructions and comments all here:
https://xdaforums.com/t/rom-11-0-unofficial-a57-lineageos-18-1.4396409/

Since I do not own the device I cannot test. Usually there is a good chance that LineageOS port works for /e/OS, but not in every case. Please try the LineageOS ROM if it works…

9

It actually worked after flashing persist fix.zip file but the camera, fingerprint, home button, all the sensors and imei are not working. Please fix these issues.

10

I can’t, I’m not the developer. Can you please try if LineageOS version has no issues

Hi rennz98

The update e-1.21 ROM was installed successfully, but there is a problem when it starts to freeze after less than a minute and random reboot
Please email me to send you a video

13

This rom is too buggy. It always get stuck in bootloop. I forgot to keep my phone on the table and kept it under my pillow. The phone started randomly bootlooping and started to heat to crazy levels. Thankfully I noticed my pillow getting crazy hot and kept it outside too cool down. Otherwise, it would’ve exploded.

14

Same issue here. I will replace it with the lineage os rom.

15

Yes, I too have the same issue.

16

Thanks all for the feedback. Basically its a port of the Lineage version without any changes, I assume that the general Lineage source is not very good

17

Please help, I’ve been searching for hours and am confused about where to find a custom recovery for the Oppo A57 (2022, CPH2387). It seems all the results I find are for the Oppo A57 (2016).

The Oppo A57 family (in marketing terms) seems to include

Branding,Marketing,	Device,		Model

Oppo,	A57,		A57,		OPPO A57
Oppo,	A57,		A57,		OPPO A57t
Oppo,	A57,		OP5355,		CPH2387
Oppo,	A57,		OP5355,		CPH2407
Oppo,	A57s/A77,	OP5353L1,	CPH2385
Oppo,	A57t,		A57,		OPPO A57t
Oppo,	OPPO A57s,	OP5353L1,	CPH2385

… but builds are specified by device, or device codename so Oppo A57 (2022, CPH2387) does not share this build or recovery.
