SWEETGlobal_V12.5.8.0 released.

I created SWEETGlobal_V12.5.8.0_SGSI by xiaoxindada-sgsi tools.

I'm curious about the detailed explanation of the gsi rom installation.

Can you tell me how wifi works?

Can you share it with us?

Thanks xiaoxindada.

This afternoon I have requested mahi39 to build MIUI 12.5.8.0-sweet, which has now been released:https://sourceforge.net/projects/gsitutorials-sgsi/files/SGSI/MIUI/，i will be try both.
[ZTE Nubia Z17  ROMs, Kernels, Recoveries, & Other ] Tims Fong:
you img file is 5.26GB,other is 5.38GB,Both need to fix screen flicker,and all can't boot on RR8.6.2,only boot on exTHmUI and Los17.1 21-10-13,all no wifi,Cam and BT work is well, but you also need to fix black screen issues, so I chose large files for further testing. Here's your screenshot.

MIUI 12.5.8.0,Only flashlights don't work (can be repaired, but don't want to), and everything else basically works.thanks:mahi39:https://sourceforge.net/projects/gsitutorials-sgsi/files/SGSI/MIUI/

Important changes:this one can boot on RR8.6.2,Because of the power consumption and charging errors on exTHmUI,So the installation methods are different in 2) and 3).

The detailed installation method is as follows, please do not ask why, just do it.

1.The conditions for the basic requirements

A.Official firmware V6.28

B.TWRP3.3.1

2.Installation

1)wipe system,data,all cache(two)

2)flash RR8.6.2.zip(note:Los17.1 no call, exTHmUI an error with power consumption and charging )

3)wipe system,data,all cache(two)

4)flash Miui12.5.8.0-Sweet-A11-SGSI-GSITutorials.img to System partition

5)wipe factory reset and reboot.

6)When entering the boot interface then reboot to recovery

7)a.flash certGSIfixAB__zero.zip (will be failed)

b.wipe cache/dalvik(Lower left corner)

c.flash certGSIphh__zero.zip(will be failed)

d.wipe cache/dalvik(Lower left corner)

e.flash GSI_Certifier-fixed.zip and Certification_Patch_V2.zip

8)Mount system and vendor,File manager>>>>system-root/system/priv-app/provision(Delete it).vendor/overlay(Delete it).copy attachment"overlay"(Unzip) to vendor.File manager>>>>vendor/overlay(Grant 0755 permissions)

9)wipe factory reset and reboot

10)Skip all access to the home screen and set wiFi password and privacy as "use device MAC"

11)Now insert your SIM card and click on the status bar "App update is ready" to log in to your Google account and update all apps.

12)go to settings Sync your Google account,Update Google Security and Google Store,Grant all permissions to all apps, including permission to install unknown apps.(Hard!!!)When all settings are complete, reboot.

Still same issues for me, distorted ringtone and no wifi(i can toggle on/off but it dosent connect to any network).

might be device specific issue, Btw for me wifi privacey is by default "use device mac" after i boot up first time.
[ZTE Nubia Z17  ROMs, Kernels, Recoveries, & Other ] Tims Fong:
idk what happen to you.see my device the Kernel version you know is boot on RR8.6.2,i am not do anythings the wifi work is very well.i think you try take the SIM card out!!!
[ZTE Nubia Z17  ROMs, Kernels, Recoveries, & Other ] CEKUU35:
Thank your for efforts.

i tried too.step by step.

set wiFi password and privacy as use device MAC ok. but can't get ip address.

does overlay belong to china device? So maybe we are having wifi problem?

File manager>>>>vendor/overlay(Grant 0755 permissions)------ only folder? is it correct?

Grant all permissions to all apps-------Can you explain with a photo from the menu? or screenrecord please?

including permission to install unknown apps -------Can you explain with a photo from the menu? or screenrecord please?

this one exTHmUI/RR/Los17.1 all can boot,but on RR reboot，on other two can't go to homescreen,becouse Z17 can't flash Permissiver_v4 or v5.i try boot on other phone,is boot on vndk29/30 ab,on vndk29 ab Cam work,on vndk30 ab Cam not work.so Z17 need nice vendor like PE/AEX/PixysOS,and the best need A11 vendor.
[ZTE Nubia Z17  ROMs, Kernels, Recoveries, & Other ] aljoscha81:
wow you got android 12 with working cam thats nice ;)

really sad that no rom is fully working for us ..... :(

do you can sign your boot image in twrp? i always got error when i try ...

i know from other gsi in the past that it needs to sign boot then flash permissiver to get propper boot .....

but for now i am also out of knowledge :(
[ZTE Nubia Z17  ROMs, Kernels, Recoveries, & Other ] Tims Fong:
for this one can't go to homescreen,just can boot on exTHmUI/RR,if you only want to boot,the key is 1.wipe system/data/all cache.2.flash exTHmUI.zip or RR8.6.2.zip.3.wipe system/data/all cache.4.flash GSI.img then will be boot.

if have A11 vendor can use for trebel base,the nubia UI V9.0 is very nice,becouse boot on A10 vendor the wifi is locked,if boot on A11 vendor the wifi is open,then can fix the Cam.

I haven't updated my ROM for a long time. I've been running Havoc 2.9 (Android 9) for a long time without issues but decided to upgrade finally.

There is a lot of testing and experimentation in this thread but I'm looking for a good stable ROM to use with full functionality.

I really liked Havoc (and other customisable ROMs like RR) but looks like they haven't updated their ROMs for almost a year.

What would the current recommendation be for a stable fully functioning ROM of whatever the best latest version (10/11/12) should be?

Update: Running RR-Q-8.7.3 for now until any suggestions come through.
[ZTE Nubia Z17  ROMs, Kernels, Recoveries, & Other ] bunta126:
I've never had this problem until the latest updates but now after flashing a new ROM I get the warning that my system is corrupt on boot.

Bootsigner dosent work on newer roms, if you need root just unzip rom and patch boot.img with magisk canary and flash it from latest twrp. Apart from RR you can use latest lineage os.

I would suggest clean flash after formating everything, if you've already done that reflash stock rom then boot into it then unlock bootloader again and reflash twrp.
[ZTE Nubia Z17  ROMs, Kernels, Recoveries, & Other ] bunta126:
My process each time I flashed ROM was to flash Stock Firmware 6.28, then lineageOS, then twrp. Would I need to unlock bootloader after (or during) that process to avoid the corrupt message?

Is it because I flashed stock rom each time that it locks the bootloader again?
[ZTE Nubia Z17  ROMs, Kernels, Recoveries, & Other ] Vi7eta:
1. Only Flashing stock rom dosent lock bootloader but booting into it locks the bootloader.

2. You dont have to flash stock rom everytime you install another rom

3. Try unlocking bootloader then flash twrp 3.3.1 then flash lineage os rom with gapps without any other modification and let it boot.

If problem still persist i would suggest to flash earlier stock build like 4.25 which can be bootsigned by twrp itself then flash latest stock then cuwtom rom.

Most important, take fastboot backup of everything.. this way if anything goes wrong it'll be a breeze to restore your phone.
[ZTE Nubia Z17  ROMs, Kernels, Recoveries, & Other ] bunta126:
Thanks, I'll give those steps a go, although I'm not entirely sure on how to "take fastboot backup of everything". Are you meaning nandroid backup from TWRP?

Also few questions:

- which is best to use for base for Q ROMs, Lineage 17.1, or RR 8.6.2? I'm not really sure what the difference between them is and how to choose which is best? (is there some third exthm option as well?)

- what method do you normally use for magisk? rename apk to zip and install from twrp?

- is it better to use ab or ab-vndklite images where the option exists?

- in almost all ROMs I try, editing the function of the hardware keys has no effect. I cannot change what menu, home or back button behavior does. Is this normal with our phone?

- cast to TV reboots phone. Is there a fix for this or a ROM where that works?

I went back to stock ROM 5.35 and the corrupt image message disappeared.

I then flashed the 6.28 stock ROM and rebooted and the message was back again straight away.

Seems my system complains as soon as I'm at 6.28 level :( (I tried 6.25 as well and message was still there)
