I wish to upgrade. Update package does not show in settings > updater
Is it because OTA is somewher else?
Do I need to upgrade manually?
Will I loose any data (along with OTP codes for even my computers)
What is the normal procedure? Can i do a upgrade with TWRP (which is on my phone, i installed it with odin) copy the e-1.20-t zip file in the root directory of the phone and install it with TWRP without formatting? Is this the way of doing it? i haven’t done any upgrades and i don’t know how to do it. There is not much information on this topic of upgrading from one to another android version…thanks in advance
Not for this one,
only when the device is still updated by the vendor, you have to flash some needed partitions before system upgrade (sometimes reinstall stock-OS to get latest firmware).
The root directory of the phone is only accessible on a rooted system, or via TWRP.
Simply copy it in the “internal-storage” that will be accessible by the recovery-e.
thank you piero so to sum up, i copy the e-1.20-t zip file to the internal-storage and then i can install the zip with TWRP without wiping or formatting. after reboot i should now have the new upgraded e-os version with my apps and data, right?
Some settings will be reverted to default.
I have not lost any data.
I did adb sideload. I didn’t know I could use e-recovery, as I have not researched subject. It definitely would be faster with update file already on device, as I don’t have reliable USB3.0 cable.
Today I tried to dirtyflash my S10+ beyond2lte from /e/OS 1.19.1-s to 1.20-t.
In TWRP with Install. No Wipe or Format anything. But before I forgot to enable USB Debugging in /e/.
The installation ended with the error below. Same with ADB sideload.
And now my S10+ only boots in TWRP. Could it be that I’ve locked myself out now?
Do you use latest TWRP ?
If not, try to update it (you can install the new version using the"install feature of the old one).
If you already have latest and cannot install /e/OS using it
You can install the recovery-e using TWRP “install” feature,
then using the recovery-e, try to install e-1.20-t with its “apply-update” feature…
