Revision history [back]

Hi everybody!

As the tittle says is easy to imagine that now i got a nice brick at my desk that time ago i used it as a phone. The history begins just as i get the message of a new update 2.0.1.11. I was at 2.0.0.. (the previous one). The update did not work the phone keept at the phase of optimizing endless so after a few days (same as [2]) i decided to do a factory reset, supposing it was gonna work.

Of course it didn't, the phone at the boot phase only shows the jolla logo and keeps for hours... so i decide to do a factory reset using the recovery menu using the [1] guide. This is the trace.

The available options are:
1) Reset device to factory state
2) Reboot device
3) Bootloader unlock [Current state: locked]
4) Shell

Type the number of the desired action and press [Enter]:

Hi everybody!

As the tittle says is easy to imagine that now i got a nice brick at my desk that time ago i used it as a phone. The history begins just as i get the message of a new update 2.0.1.11. I was at 2.0.0.. (the previous one). The update did not work the phone keept at the phase of optimizing endless so after a few days (same as [2]) i decided to do a factory reset, supposing it was gonna work.

Of course it didn't, the phone at the boot phase only shows the jolla logo and keeps for hours... so i decide to do a factory reset using the recovery menu using the [1] guide. This is the trace.

Jolla Recovery v0.3.1

Welcome to the recovery tool!
The available options are:
1) Reset device to factory state
2) Reboot device
3) Bootloader unlock [Current state: locked]
4) Shell
5) Try btrfs recovery if your device is in bootloop
6) Exit
Type the number of the desired action and press [Enter]:
4

If you continue, this may void your warranty. Are you really SURE? [y/N] y[OK] N

ALL DATA WILL BE ERASED! Clears everything from the device and reverts the
software back to factory state. This means LOSING EVERYTHING you have added to
the device (e.g. updates, apps, accounts, contacts, photos and other media).
Are you really SURE? [y/N] y[CLEANUP] Starting cleanup!

Nothing more happens....

I think the problem can be related to [3] Now im now doing a balance on the recovery mode, to see if it can help.

Hi everybody!

As the tittle says is easy to imagine that now i got a nice brick at my desk that time ago i used it as a phone. The history begins just as i get the message of a new update 2.0.1.11. I was at 2.0.0.. (the previous one). The update did not work the phone keept at the phase of optimizing endless so after a few days (same as [2]) i decided to do a factory reset, supposing it was gonna work.

Of course it didn't, the phone at the boot phase only shows the jolla logo and keeps for hours... so i decide to do a factory reset using the recovery menu using the [1] guide. This is the trace.

Welcome to the recovery tool!
The available options are:
1) Reset device to factory state
2) Reboot device
3) Bootloader unlock [Current state: locked]
4) Shell
5) Try btrfs recovery if your device is in bootloop
6) Exit
Type the number of the desired action and press [Enter]:

If you continue, this may void your warranty. Are you really SURE? [y/N] y[OK] N

ALL DATA WILL BE ERASED! Clears everything from the device and reverts the
software back to factory state. This means LOSING EVERYTHING you have added to
the device (e.g. updates, apps, accounts, contacts, photos and other media).

Nothing more happens....

I think the problem can be related to [3] Now im now doing a balance on the recovery mode, to see if it can help.

Hi everybody!

As the tittle says is easy to imagine that now i got a nice brick at my desk that time ago i used it as a phone. The history begins just as i get the message of a new update 2.0.1.11. I was at 2.0.0.. (the previous one). The update did not work the phone keept at the phase of optimizing endless so after a few days (same as [2]) [2] and [4]) i decided to do a factory reset, supposing it was gonna work.

Of course it didn't, the phone at the boot phase only shows the jolla logo and keeps for hours... so i decide to do a factory reset using the recovery menu using the [1] guide. This is the trace.

Jolla Recovery v0.3.1

Welcome to the recovery tool!
The available options are:
1) Reset device to factory state
2) Reboot device
3) Bootloader unlock [Current state: locked]
4) Shell
5) Try btrfs recovery if your device is in bootloop
6) Exit
Type the number of the desired action and press [Enter]:
4

If you continue, this may void your warranty. Are you really SURE? [y/N] y[OK] N

ALL DATA WILL BE ERASED! Clears everything from the device and reverts the
software back to factory state. This means LOSING EVERYTHING you have added to
the device (e.g. updates, apps, accounts, contacts, photos and other media).
Are you really SURE? [y/N] y[CLEANUP] Starting cleanup!

Create a snapshot of '/mnt/factory-@' in '/mnt/@'
Create a snapshot of '/mnt/factory-@home' in '/mnt/@home'

Nothing more happens....

I think the problem can be related to [3] Now im now doing a balance on the recovery mode, to see if it can help.

Hi everybody!

As the tittle says is easy to imagine that now i got a nice brick at my desk that time ago i used it as a phone. The history begins just as i get the message of a new update 2.0.1.11. I was at 2.0.0.. (the previous one). The update did not work the phone keept at the phase of optimizing endless so after a few days (same as [2] and [4]) i decided to do a factory reset, supposing it was gonna work.

Of course it didn't, the phone at the boot phase only shows the jolla logo and keeps for hours... so i decide to do a factory reset using the recovery menu using the [1] guide. This is the trace.

Jolla Recovery v0.3.1

Welcome to the recovery tool!
The available options are:
1) Reset device to factory state
2) Reboot device
3) Bootloader unlock [Current state: locked]
4) Shell
5) Try btrfs recovery if your device is in bootloop
6) Exit
Type the number of the desired action and press [Enter]:
4

If you continue, this may void your warranty. Are you really SURE? [y/N] y[OK] N
o lockcode has been set. Proceeding...

ALL DATA WILL BE ERASED! Clears everything from the device and reverts the
software back to factory state. This means LOSING EVERYTHING you have added to
the device (e.g. updates, apps, accounts, contacts, photos and other media).
Are you really SURE? [y/N] y[CLEANUP] Starting cleanup!

Restoring factory subvolumes...
Create a snapshot of '/mnt/factory-@' in '/mnt/@'
Create a snapshot of '/mnt/factory-@home' in '/mnt/@home'

FSSync '/mnt'

Nothing more happens....

I think the problem can be related to [3] Now im now doing a balance on the recovery mode, to see if it can help.
