Does Dopamine work if you sideload it normally?

如果你正常旁加载多巴胺，它起作用吗？

No Dopamine, but I have successfully installed TrollStore by TrollRestore

I'm from issue 21, this one is the same

I've made a small research (probably wrong) and that's what I've found out:
According to appledb.dev, iPhone11,2 and iPhone12,8 never had iOS 15.7.2.
iPad8,10 had 15.7.2 officially.
To my mind, https://api.appledb.dev/ios/main.json.xz is fetching kinda the same info in json format, but as there are no iPhone11,2 and iPhone 12,8 with iOS 15.7.2 in this file - we got errors.
According to https://api.appledb.dev/ios/main.json:
Devices map for 15.7.2: "iPhone8,1", "iPhone8,2", "iPhone8,4","iPhone9,1", "iPhone9,2", "iPhone9,3","iPhone9,4", "iPod9,1"
For iPhone 12,8 + 15.7.2 (only for RC version, I have stable version) I could find only one line in this json:
"iPhone12,8": {
"ota": "https://updates.cdn-apple.com/2022FallFCS/patches/012-91580/C89641F0-BBAB-4547-86E3-EBEB5EB08544/com_apple_MobileAsset_SoftwareUpdate/151bb9a8ea9fc62aab330be0772beece7d3eec38.zip"
}
I think, that if my iPhone 12,8 will use firmware url from 15.7.2 RC, it should work fine (I don't know, how can I do it manually).

I think you're right, Manual mode should solve the problem.

I think you're right, Manual mode should solve the problem.

I have done it, and it works!

1. Forked libgrabkernel2
2. In src/appledb.m I hardcoded firmware link for my iPhone. I used a link for 15.7.2 beta
3. Code for appledb. Please, don't use it for other models/firmware, you will brick your iOS device, this is just my example, but you can modify hardcode link

//  appledb.m
#import <Foundation/Foundation.h>
#import <sys/utsname.h>
#if !TARGET_OS_OSX
#import <UIKit/UIKit.h>
#endif
#import <sys/sysctl.h>
#import "utils.h"

// Change const with my url
#define FIXED_FIRMWARE_URL @"https://updates.cdn-apple.com/2022FallFCS/patches/012-91580/C89641F0-BBAB-4547-86E3-EBEB5EB08544/com_apple_MobileAsset_SoftwareUpdate/151bb9a8ea9fc62aab330be0772beece7d3eec38.zip"

NSString *getFirmwareURL(bool *isOTA) {
    *isOTA = YES; // If it is not OTA, use "NO"
    return FIXED_FIRMWARE_URL;
}

5. Git clone libgrabkernel2 in MacOS. Type "Make" in terminal - copy files libgrabkernel2.h and libgrabkernel2.a from output folder
6. Download trollinstallerx Source code (zip)
7. In TrollInstallerX-1.0.3\TrollInstallerX\External\lib change libgrabkernel2.a and in TrollInstallerX-1.0.3\TrollInstallerX\External\include\libgrabkernel2 change libgrabkernel2.h
8. sh build.sh in terminal
9. install trollinstallerX
10. Trollstored the device
    May be there is another easier way, but this is the method, how I solved it

Thanks for guidance, This has greatly advanced my progress, I will try it on holiday.

@alfiecg24 Hello, based on the solution proposed by @cdK1337 , could u let me know if the bug in 15.7.2 will be fixed in the next version of Trollinstaller?
