Hi,

since I'm not 100% regarding the procedure and want to make sure I don't do any major errors.
I have a an 'older' weekly rom installed with the fastboot method and I want to update to the newest weekly rom.

How do I need to proceed?
Would I need to install/flash TWRP first and then proceed with the regular update procedure with the new rom?
I assume this is the right TWRP version: link

Thanks in advance for a reply.

3. Run TWRP fastboot command
Code:

4. Enter (Password/PIN/Pattern) of the lock screen when prompted

@gogocar62- thanks for the fast and clear feedback.

now I am stuck at step 4 - somehow my pattern is not accepted.
I changed my pass to a pin - still the same issue...

removing the lock screen password did the magic ;)

I cant flash the TWRP, "FAILED error flashing partition : volume full"

EDIT BOOT not Flash was the magik....

Just a silly question, to install TWRP roots the phone by itself? Or just allows to it? And my user data, remains or I need to save it before?
 
on step 3 of install. I've put my phone into fastboot but adb is just saying <waiting for any device>
 
Okay so when phone is connected and booted ./adb devices sees the device. If I reboot to fastboot via it, the phone can't be seen. What am I doing wrong?
 
Okay fixed it to get TWRP installed. I had to download the latest MI Unlock Tool and install the drivers with file 'MiUsbDriver'. This then allowed the device to be seen in fastboot correctly. Then installed TWRP and OS updated through TWRP.
 
Does anyone have problem with installing some app from the app store. After the update playstore give "App requires external storage" error when installing some app.

that is normal….

Fastboot commands are working if your device is in Fastboot-Mode and ADB (Android Debug Bridge) is working while your device ist up an running.

if you are in fastboot mode with your device you have to type
# fastboot devices
instead of
# adb devices

Hello guys,
I am trying to update my Poco F3 to the latest stable version.
I do all the steps, put the phone in fastboot and start TWRP, however even having the update on the phone, TWRP does not show me any file, either in the internal memory, either on sdcard.

Does anyone know how to solve this?
 
Thanks @gogocar62! I think i'm using another verion of TWRP. Now, my Poco F3 is on 13.0.9 ;)
Android 12 brought changes to encryption, if you try to use a recovery built for Android 11 it will try to decrypt using old method and fail.

The correct solution is to update your recovery to one built for A12. The quick'n'dirty solution is to disable your screen lock (settings > Passwords & security > screen lock > tap the 'turn off screen lock' text at the bottom) before rebooting to your existing recovery. Don't forget to re-enable when you boot back to Android!
 
Sorry for the newbie question but i currently run a fastboot image on my xiaomi mi 11 ultra and would like to upgrade to the latest MIUI 14 stable rom which is TWRP.
Will i lose my data on my phone if i install it with this manual, if yes: can i load the files from a backup i create with the build in backup tool or do i have to setup everything again after switching to TWRP?
