Failing to sideload e-0.23-r-202204 to a Mi A2

[marcvolovic]

Hi,

I am trying to migrate from my old phone to a (well, also old) Xioami Mi A2 (jasmine_sprout).

Trying to sideload the e-0.23-202204…zip image results in a message “E:Signature verification failed” on the device itself.

Trying to install nevertheless (i.e. clicking YES on the device) results in a error applying update 29 (errorcode kDownloadOperationHashMismatch).

Can anyone suggest what I am doing wrong?

(just to be on the safe side, the e-zip and the recoveryimg are the same release)

Many thanks in advance.

Hi,

Not much knowledge about /e/ Recovery here, but I’ve faced a similar problem in the past with TRWP …

Within TWRP, solved by copying (adb push) the file to /data then using TWRP’s Install button.
That’s how I’m installing every ROM image now, never failed me

Thanks for the suggestion. I tried to do what you suggested, and the results are really strange.

First, it took quite a bit of effort to flash the device with TWRP. But, in the end that worked.

What is NOT working is pushing the e-0.23 file into the device. On slot A, the push stops around 18-20% of the upload. On slot B, the push stops around 90% of the upload.

I am beginning to wonder whether the flash on the device is shot.

Happy to read your success

But you may want to investigate further…

At first, you may try another USB cable, connected to an USB2 port if your computer has one (or a USB2 hub).

Are you sure you have enough free space on your device’s storage?
Within an ADB shell you can check with cd /somewhere then df -h . .
You may also search for another place with df -h (without the dot), but please be aware that some may not be your best bet to store ROM images (i.e. reserved partitions like EFS).

It’s very uncommon to have Flash chips problems, but I think that in this case you may have noticed it before with some weird behavior…

Ok,

Your email was a very good lead. Instead of pushing to /sdcard, I now pushed to /data (both of which are mounted to the same MMC device, so I was not hopeful).

However, adb push to /data worked and the INSTALL from the TWRP menu also seemed to work, until it failed (at the very end) with failing to mount system_root (I THINK).

I did a factory reset, wiped cache, data and all other bits and pieces. Now let’s have another go.

…aaaaand, a different failure this time.

In step 1/2, the process failed and reported kDownloadOperationExecutionError.

Rather strange

Hi,

Alas, it is jot a success yet. The previous phone was a breeze.

There should be no lack of space - but I will check.

To ensure your device health, you may try to install LineageOS.

i had troubles flashing and updating on Mi A2, very helpful for me was

Xiaomi - Mi A2 - jasmine_sprout - Documentation Suggestions

@Manoj , there are some points to be corrected and added, on the page: https://doc.e.foundation/devices/jasmine_sprout/install After point 7. on “Unlocking the bootloader”, it should be added: (optional) If, when trying to flash the ROM, you get a message about not having permission on critical partitions, this command should be run in fastboot mode: fastboot flashing unlock_critical This command, just like during the bootloader unlock process, will erase all information on the device. On…

[marcvolovic]

I unlock both - critical and non-ctirical.
So far, no joy.
Damn

[marcvolovic]

Ok, i’ll give lineage a go.

[kamamira]

After i followed the Information at the end of the linked text:
" Once in fastboot mode, check which slot is active:
fastboot getvar current-slot

And activate the inactive slot:
fastboot set_active a
or
fastboot set_active b

After marking the previously inactive slot as active, reboot the device normally:
fastboot reboot"

i could start /e/ os

@marcvolovic , I always use the latest unofficial TWRP (with good Android 11 support and decrypts) from a well known developer (Nebrassy) of the Mi A2 (although he hasn’t released anything new in a while).
TWRP 3.5.1-jasmine_sprout

With that TWRP, I’ve never had any problems installing /e/OS (nor LienageOS) by sideload.
What’s more, I never flash TWRP, I simply boot into it, and from it I perform the whole process. In short, I keep the one that comes with the ROM.
