Question Downgrade question - Vivo X Fold

Hi.
I just downloaded downgrader-setup.exe from vivo.
I got this screen to start download an older android version (now im on OriginOs 3)
Before im doing anything stupid, can i downgrade to that Origin OS 2? Is this will help me to unlock bootloader so i can root it?
Thank you

Yes, I did downgraded from Origin OS 3 to Origin OS 2 using the same tool. Please make sure you clear all caches and hard reset the phone.
Also, google translate is you best friend

@manee can you share me the root steps that you used? Thank you!

Sorry I didn't do or root my phone. It just this tool I have used and google translate to translate chinese into english. For downgrading the phone to Android 12, there is no root required.
Thanks

this tool will not downgrade your firmware to unlockable version
I have an idea. Maybe this tool just send normal fw without modified metada and things about downgrading are inside misc partition. Also most likely fw wil be copied to /data/vivo-updater which is reachable with uid1000 (system) through debuggable app com.vivo.vtool.
So maybe for dawngrade you just need
1. use official utility
2. stop
3. replace fw in /data/vivo-updater with fw with security patch from april

i can try.
Questions:
1. Where i can find april or lower fw?
2. How can i do the uid1000 (system) through debuggable app? Any tutorial?
Thank you!

Scusa se non ho eseguito o effettuato il root del mio telefono. È solo questo strumento che ho usato e google translate per tradurre il cinese in inglese. Per eseguire il downgrade del telefono ad Android 12, non è richiesto il root.

Hi
If you are patient, and willing to help, I might be able to get a partially working version of Android on your phone, but note that for now we don't have any connectivity options working, so neither cellular networks nor Wi-Fi works.
It's up to you if you want to help or not, but if you do, please post your e-mail address, so I can send you an invitation to our development group
And one more time: even if we succeed in porting, we did not reach the point where the ROM becomes usable as a daily driver

Could this port run on other MSM8960 Lumias like Lumia 925 (RM-892)?

I am curious how you are able to unlock the bootloader on the 1320 to get the Android port to run? Or are you dual booting or doing some other method of running another OS on this model.
I have several 1520's and realizing I could not do much with them except update them to W10M, I went and found a working cheaper 1320. Come to realize there is not a direct method to unlocking the bootloader on the 1320 so far that I have found...or is there?
feherneoh said:
WPInternals can unlock the bootloader of 1320 just fine

Maybe I have not run across the right thread yet. I thought I understood that an SBL3 from an engineering rom was needed to bootloader unlock. Which of the available sbl3 files is needed? Or can you point me to a thread discussion about this model and unlocking the boot loader on it?
Ok thanks for the information. Not being able to use an SBL3 has other limitations too not just mass storage being unavailable?
From what you mentioned, sounds like a dual boot scenario in the works.
feherneoh said:
As far as I know, there are no other limitations. If you mean Windows+Android, that would need some kind of fix, so UEFI does not kill the Linux kernel we are trying to boot. For now, we use a custom bootloader in place of UEFI, but that means booting WP is not possible.

W10 on my lumia 1320 doesn't works. Why?
Thank you for your attention.
I have a nokia lumia 1320.
When microsoft decided not to create the windows 10 mobile update, it forced me to stop using the phone:
no longer worked, with the w 8.1 installed.
In May 2019 I found and followed a guide to forcibly install, after flashing and downgrading the windows 10 operating system on my nokia lumia 1320.
The update was successful.
In appearance everything worked.
Unfortunately I had to note that it is impossible to type texts in the applications: the keyboard does not work in messenger, on browsers and even in the application of SMS messages.
I could not find a solution in 5 months spent on the internet, looking at various tutorials of people who believe themselves to be expert programmers or lamers.
I therefore decided to install an operating system based on android, for my nokia lumia 1320.
Can anyone tell me a working guide to do this?
Thank you for your kind attention and for the help you want to give me.
Grazie per l'attenzione che mi riserverete.
Io ho un nokia lumia 1320.
Quando la microsoft ha deciso di non creare l'aggiornamento al windows 10 mobile, mi ha costretto a non utilizzare più il telefono:
non funzionava più, con il w 8.1 installato.
A maggio del 2019 ho trovato e seguito una guida per installare forzatamente, dopo il flashing e il downgrading il sistema operativo windows 10 sul mio nokia lumia 1320.
L'aggiornamento è riuscito.
in apparenza funzionava tutto.
Purtroppo ho dovuto constatare che è impossibile digitare dei testi nelle applicazioni: la tastiera non funziona in messenger, sui browser e nemmeno nell'applicazione dei messaggi telefonici sms.
Non sono riuscito a trovare una soluzione in ben 5 mesi trascorsi a girare su internet a vuoto, guardando vari tutorial di persone che si credono esperti programmatori o lamer.
Ho quindi deciso di installare un sistema operativo basato su android, per il mio nokia lumia 1320.
Qualcuno mi può indicare una guida funzionante per fare questo?
Grazie per la cortese attenzione e per l'aiuto che vorrete darmi.

Which version your firmware is using now? For me, my firmware was downgraded to 10.1.0.131 because i need to install GMS but after that, i was unable to receive OTA. So that's why i used hisuite proxy to upgrade to 10.1.0.182 and after upgraded, i can receive the OTA again to 11.x
Note: Mine is on different region C636 so the firmware version might be different as well

Normally, i prefer to upgrade to latest 10.1.x version before upgrading to 11.x. So not sure if upgrading directly to 11.x might cause some issue or not. Have you tried using hi suite(without hi proxy) to upgrade?

Yeah that should be the firmware compatible with your phone region. Probably you can try upgrading to 11 using hi suite proxy but make sure to watch the youtube tutorial on how to upgrade to 11. For me, i upgraded to 11 using OTA

Hi Wievi, i tried to install some firmwares, 10.150, 10.135, 11.168 and is the same, when the process begins in my phone restarting an error appears and restart the system.

I think that Huawei use a specific firmware version during transition to/from one EMUI major update/downgrade. You can not jump from the oldest EMUi10.1 to newer EMUi11 in one step.
Is there a way to know the original region code so get the right firmware? I'm stucked at c605
C605 is Latin America.

This beta sideload needs latest September Patch while Samsung don't push it to non beta regions on purpose.
You should install latest compatible builds for your device from other regions and then try sideload beta! Or simply wait for the further updates for your area!

First you need to have the September version. Second is to have the latest version of adb.
This is required version.

It should possible but must needed rooted device.
But presonally I believe it's a great security feature. You will immediately come to know if your device is hacked and some one spying by using your device camera/mic.
Ok, I fixed it by downgrading to android 11 3.1 ;D

Question RMX3311 GDPR version downgrade A13 to A12

Hello.
I own an european realme gt2. Current software version: RMX3311_11.C.08_1080_202301111307.
I have been trying to downgrade to the last version of android 12 ( RMX3311_11.A.22_0220_202211010914 ) and I can't seem to make it work.
I downloaded the OTA package ( RMX3311_11.A.22_0220_202211010914 ) using realme ota tool and tried to install it using local install from the update menu on the phone -> I am getting a verification failed error.
Is there any method to downgrade to android 12?
Version C.08 is Android 13 and A.22 is Android 12 therefore authentication failed.
Rollback i found only for india RMX3312.

That's the reason I didn't update to Android 13 yet. That update notification is there for nearly one month and I'll let it stay there until a rollback package is available for rmx3311. Until now you cannot downgrade the European model to Android 12 since there is no rollback package. Only for rmx3312 Indian model it is available.
Why would you want to downgrade? A13 is working fine no issues for me.
Do a hard reset after update otherwise you might have some problems especially with battery standby.

Incredible ! realme so bad !
I've recently bought a GT2, probably from a really old stock, which is on RMX3311_11.A.22 (this is already updated by me) and I might've been scammed, since the phone had fingerprints out of the sealed box, idk.
I've ran the OTA tool: realme-ota RMX3311EEA RMX3311_11.A.22_0220_202211010914 3 -r 3 -o
But it only returns a json for the next update, RMX3311_11.C.06_1060_202212011207. And the A12 update zip got deleted during installation, so... Is there another way to dump mine?
(Also thanks to the devs that they created a whole pip package and an installer, which couldn't detect or install python, so I had to bootup a VM just for the tool, because I was too lazy to patch the installer script or install manually. So I'm planning to rewrite it in dotnet to make it usable.)

Mais il ne renvoie qu'un json pour la prochaine mise à jour, RMX3311_11.C.06_1060_202212011207. Et le zip de la mise à jour A12 a été supprimé lors de l'installation, alors ... Existe-t-il un autre moyen de vider le mien?
(Grâce également aux développeurs qui ont créé un package pip complet et un programme d'installation, qui ne pouvaient pas détecter ou installer python, j'ai donc dû démarrer une machine virtuelle uniquement pour l'outil, car j'étais trop paresseux pour corriger le script d'installation ou installer manuellement. Je prévois donc de le réécrire en dotnet pour le rendre utilisable.)

In the attempt of changing from rmx3311 to rmx3312, I used the oneplus updater app for Android 13 on my rmx3311 running still android 12 and surprise: it installed the rollback package ment for the Indian version.
So I changed my European rmx3311 to the Indian rmx3312 variant by using only the oneplus local updater app.
Now, I believe that by cross-installing a different region OTA rollback package my device lost IMEI and Baseband because it doesn't recognize anymore my SIM card.
I wanted to change to rmx3312 because the indiant variant have the possibility to unlock the bootloader.
Is there any chance I can recover my IMEI and Baseband?
Also try to install Full OTA RMX3311

That would be my first option.
But I would like to manage to preserve the Indian variant since it is the only one with the unlockable bootloader.
Also, I never had believed that it is possible to change region so easy. And having locked bootloader.
It has already been tried and the result was as you wrote. Reverting to the original version helped. For GT 2 Pro, the device model is the same (RMX3301). GT 2 changes the version of RMX3311 to RMX3312.

Then maybe I can unlock the bootloader on this variant (RMX3312) and after that I'll install the RMX3311 package. Maybe the bootloader will stay unlocked?!?
Changing the region via Full OTA will certainly not overwrite all partitions. Manifest:Image will be 1b:44 where 1b stands for India and 44 stands for Europe.
In such a situation, a little is enough and the brick is born.

Thanks. So better to take no risk since there is not a free unbrick tool for these devices. And the bootloader cannot be unlocked even in the RMX3312 since i don't have a valid IMEI number.
So, to revert back to RMX3311 i must repeat the process using the Oneplus updater application? And what firmware should i install?
Right now i am on Android 13 for the RMX3312 since i have done the regular OTA update hopping it will solve something about the IMEI.
