I have a OnePlus 9 Pro 5G (model LE2127) on t-mobile.
Following instructions at: https://doc.e.foundation/devices/lemonadep/install
- I unlocked the bootloader after flashing an unlock token from OnePlus (www.oneplus.com/unlock_token).
- I flashed the latest recovery (recovery-e-0.23-r-20220405175826-dev-lemonadep.img) and rebooted to recovery.
- e-recovery booted. I followed the pre-installation instructions to adb sideload copy-partitions-20210323_1922.zip
- I followed the steps for installing e/OS from recovery:
- Select
Factory reset
- Select
Format data / Factory reset
option - Next screen will display a warning that this action cannot be undone
- Select
Format data
to proceed orCancel
if you want to go back - If you selected
Format data
…the format process will complete - Display will now return to the Factory Reset screen
Tip: Use the volume up key to choose the arrow at the top to go back to main screen - Select
Apply Update
and in next screenApply update from adb
- In the next screen, the device is now in sideload mode
Note at this point the Cancel option is highlighted that does not mean you have canceled the action. The device is in adb sideload mode.
- On your PC type begin adb sideload. Type the below command in a console
adb sideload downloaded_file_name.zip
Replace downloaded_file_name.zip with the name of the /e/ OS file you downloaded in the previous section
I sideloaded the latest version of /e/OS:
adb sideload e-0.23-r-20220405175826-dev-lemonadep.zip
- Press
enter
key on the keyboard to start the sideloading The screen will show the progress percentage…This might pause at 47% - Give it some time
- The PC console will now display
Total xfer: 1.00x
- The phone screen will now display some text with a message similar to
Script succeeded result was [1.000000]
This means that the install was successful
- Use the
volume key
to select theback arrow
on the top left of the phone screen - Go back to the main screen and select
Reboot system now
The reboot process may take 5 - 10 minutes
Success: Congratulations !! Your phone should now be booting into /e/OS !!
Things started to go awry at 10.
Update: On watching the phone screen more closely on repeated attempts, I see:
E:Failed to bind mount /mnt/staging/emulated/media/0 to /storage/emulated: No such file or directory
E:emulated failed to bind mount /mnt/staging/emulated/media/0 on /storage/emulated: No such file or directory, prior to the message “Now send the package you want to apply to the device with …”. I don’t know if this should be expected. FWIW, this phone does not have an SD card slot.
At 47% the process abruptly finished and on the phone screen the display was image validation completed (result 0) - which I figure was NOT a good sign. However, I decided to try to try the reboot anyway. Upon reboot the phone came up in FastBoot mode. Selecting Start brought me back to FastBoot mode. At this point I figured the image flash failed and I should retry it. From FastBoot, I booted back to Recovery, which worked. From there, I repeated the installation starting with step 7. This time, there was a pause at 47% and the phone display showed:
Supported API: 3
Finding update package…
Verifying update package…
Update package verification took 184.0 s (result 0).
Installing update…
Step 1/2
Step 2/2
The PC console showed Total xfer 1.00x, but result was 0 again.
At this point, the phone only boots to FastBoot mode. Selecting Start, Recovery, or Restart bootloader all result in FastBoot mode. The only other options are Show Barcode and Power Off. Power Off, then On again goes to FastBoot mode. I have tried flashing Recovery again from FastBoot with fastboot flash boot recovery-e-0.23-r-20220405175826-dev-lemonadep.img, which gets me this on the PC console:
target reported max download size of 805306368 bytes
sending ‘boot’ (196608 KB)…
OKAY [ 4.192s]
writing ‘boot’…
OKAY [ 0.571s]
finished. total time: 4.778s
The phone display remains at the FastBoot menu with no updates. Attempting to boot recovery still returns me to the FastBoot menu instead. I also tried the previous version of recovery with fastboot flash boot recovery-e-0.23-r-20220324172928-dev-lemonadep.img with the same result.
I considered trying to install a GSI (doc.e.foundation/support-topics/install-GSI.html) since my model number is not listed on the OnePlus 9 Pro info screen (doc.e.foundation/devices/lemonadep), however, I don’t have the treble info and can’t boot my phone to install the treble info app.
Any advise and assistance to recover a functional phone, preferably with /e/OS is appreciated.
