Note 3 Downgrade

kowal · 07-23-2022, 04:23 AM

Hi
Is a possibility to downgrade note 3 from last update 3.2.2?
I have problems with normal refresh mode - it works worse than fast mode in the previous version.

I find upx file with prev version but android kernel blocks to do prev updates.

Yes, but it might be complicated.
Basically, you need to decrypt the old update.upx to get the normal update.zip
Then you need to modify META-INF/com/google/android/updater-script
You need to edit the first line or two to eliminate the update newer than build constraint.
Then comes the problem with actually installing the modified update.

On my Poke3 I have a custom recovery that can install updates from a USB flash drive. It would be possible to make the same thing for Note 3 but it's pretty difficult if I don't own one and I have to do things by instruction over the net.

The problem without this is that /data is encrypted so you can't mount it (easily?).
Without /data you really have no place to put a 1.5 GB update.
You could use a USB flash and connect to ADB over WiFi and do it that way.
This sets ADB to use WiFi on port 5555. (Make sure you can access this before you switch. Although a reset should clear it back to USB.)

Code:

$ setprop service.adb.tcp.port 5555

I'm not saying that there aren't other ways to do this, but this is what I know.

If you are considering this and don't have one, order a USB Type C OTG adapter cable today.

Edit: For a second I thought that the Note 3 had A/B, it doesn't. If it did you could have just swapped slots and got your last version.

My Onyx devices, including the original Note, just updated to firmware version 3.2.3.

Could it be that there is an update available for your Note 3 which might address the issues you are experiencing?

Ok when i have zip file with changed META DATA, how can i encrypt it to upx file? or how to install this update from zip?

You don't. When we get there you install the zip.

First you need a recovery with ADB access.
Do you have EDL? Can you pull a copy of recovery?
It would be good if you can pull a copy because then you have a backup.
It's also better raw material for me to work with.

If not, pull a copy of boot off the latest update.
I'll need to modify that then you can test it.
Once we have a working, rooted recovery we can proceed.

Please stay on the line, your call is important to us.

I never do such things.
Can you post a instruction how to do it?

Renate · 07-25-2022, 07:54 AM

Prerequisite: You have to have ADB and be conversant with it.

Getting a partition with rooted ADB
Is your Note3 rooted? Do you have a # prompt in ADB shell?

Code:

C:\>adb shell
# dd if=/dev/block/by-name/recovery of=/sdcard/recovery.img
Transferred a zillion blocks
# ^D
C:\>adb pull sdcard/recovery.img

Getting a partition with EDL
Go to http://www.temblast.com/edl.htm and read the instructions.
Download the loader at "this loader" link and rename it something short.

Code:

C:\>adb reboot edl

Use Zadig and install a WinUSB Windows driver on 05c6/9008.

Code:

C:\>edl.exe /lnote3.bin

(Note that that is slash-ell-whatever-you-renamed-it.)
It should print out a bunch of stuff, including "Waiting for Firehose, Ok".

Code:

C:\>edl.exe /u /r /t /precovery recovery.img

(The /u is because you're UFS. Other Onyx models may not use that flag.)
If you got what you wanted, just:

Code:

C:\>edl.exe /z

kowal · 07-25-2022, 02:53 PM

is any other option without root?

Renate · 07-25-2022, 03:02 PM

EDL method doesn't require root.
