OK, so assuming after âfastboot set_active otherâ the unit is booting from slot 1 to stock ROM, then I can set USB debugging, then âfastboot flash recovery-eâŚ.â on the same slot 1 (with stock rom)?
And which recovery? I assume not the latest (e-3.4-âŚ.), but the previous one: ârecovery-IMG-e-3.3-a15-20251213556761-community-dubai.zip [SHA256] â
right?
before all,
you could first check if âUSB debuggingâ is not already enable on slot_b
in recovery mode run :
adb devices
output like ârecoveryâ is good
output like âunauthorizedâ is bad
C:\WINDOWS\system32>fastboot set_active other
Setting current slot to âaâ OKAY [ 0.312s]
Finished. Total time: 0.318s
So originallly it was slot B, now I have switched to slot A. Then, still in fastboot mode:
C:\WINDOWS\system32>adb devices
List of devices attached
So nothing is displayed
Or should I first start the unit?
this is normal as adb only work in recovery mode and normal mode
the idea was to be sure if the slot_b where e-3.4 is have âUSB debuggingâ or not
So when I start now the unit (slot A instead of B) I get following message:
âCanât load Andrid System. Your data may be corruptâŚâ
And now?
Try Again or Factory data reset?
Or the Back arrow button?
C:\WINDOWS\system32>adb devices
List of devices attached
xxxxxxxxxxxx unauthorized
So at slot A adb communication works
but âUSB debuggingâ is not authorized
so
back to fastboot mode
fastboot set_active b
boot to recovery-e
adb devices
I am in the recovery menu, I can choose:
Reboot System
Apply update
factory reset
advanced
What should I choose?
nothing, just try
adb devices
C:\Users\Standard>adb devices
List of devices attached
xxxxxxxxxxx unauthorized
(I am still at slot A)
â advanced â enable adbâŚ
try
adb devices
C:\Users\Standard>adb devices
List of devices attached
xxxxx recovery
so please switch to initial slot_b
and check for adb devices
as in post 28, 29, 30, 31, 32
but for this I need to switch to fastbooot moder, ok?
So advanced â power OFF â> Power button + volume lower-button
ok?
or
â advanced â reboot to booloader
or
adb reboot bootloader
should also work
OK, it worked.. I have switched to slot B
then START to normal mode
adb devices does not found any device
Same again on same slot B but start to recovery mode, then advanced â enable adb
Result:
C:\Users\Standard>adb devices
List of devices attached
xxxxxxxx recovery
So adb is workking now on oriiginal slot B
so you should be able to flash e-3.3
â apply update â apply from ADB
adb sideload path-to-e-3.3-xxxxxxxxxxxxxxx.zip
(BUT WITHOUT FACTORY-RESET)
ok, many many thanks to you so far. I have to leave now but I will proceed later today. Then I will write an update here
Hi, Iâm back, I have downloaded e-3.3-a15 and recovery-IMG-e3.3-a15
But now I have one question:
Some posts above you wrote:
fastboot flash recovery-e on slot_b
then adb sideload e-3.3 (BUT WITHOUT FACTORY-RESET)
Now you write:
â apply update â apply from ADB
adb sideload path-to-e-3.3-xxxxxxxxxxxxxxx.zip
Sorry, but I am not sure how to perform this in the correct way. Starting in Fastboot mode, could you please describe this in a little more detail?
I am still on slot B, so I assume:
Is this ok and please describe which files needs to be flashed, zip, img, etc.?
sorry, i did not know witch slot_a or slot_b was active and wanted to avoid repetition of âthe other oneâ,
now i donât know what is the better slot to flash
It seems equal⌠@aibd
Would you like to flip a coin ?

TAKE THE CORRUPTED ONE
- First in fastboot mode
run :
fastboot flash path-to-recovery-e-3.3-a15-xxxxxxxxxxx.img- Then Start to Recovery Mode
- (try first without â advanced â enable adb)
- Apply Update â from ADB
run :
adb sideload path-to-e-3.3-a15-xxxxxxxxxx.zip
