Acer-Club.ru got hands on a JellyBean leak for the CloudMobile (thanks to them). The other good news is that it have an unlockable bootloader. "fastboot oem unlock" is back.


So, you will need :

- Installed drivers for the phone. (You can find them here)
- AcerDownloadTools (also known as ADT) to flash the firmware.
- Leaked firmware


Extract both ADT and firmware.
Launch ADT with acer_DownloadTool.exe.

Reboot the phone in bootloader by removing batery, insert it again and then plug your phone with USB cable while pressing Vol+.
You should see "boot mode: fastboot".

Select "Mobile Phone" tab, select the folder where you extract the firmware and tick checkboxes as shown below :

Click "Start" button and wait ~5min until the phone reboot by itself.

Once booted, we will know unlock bootloader. For that, reboot again in bootloader, then launch command :

fastboot -i 0x0502 oem unlock

If you don't know how to do that, you can download this automated script : http://vache-android...auto_unlock.zip. Unzip the "auto_unlock" folder then launch "unlock_CM.bat" when booted in bootloader.


Enjoy you're updated/unlocked CloudMobile. You can now safely flash the recovery.

Something strange here :

Looks like you didn't untick "Flash bootloader before bin". (or just for the screenshot )
You have a Acer_AV041_S500_RV41RB01_WW_GEN1 where the leak is Acer_AV051_S500_RV14RB02_WW_GEN1 ?!?

You sure this is the good log ? (LogFile/Date/Log_date_time_UI.txt)

So this is not the good log file, check my previous post.

That's a bad news : Leak can be flashd on CPU_TYPE=8260a-3, where you may have CPU_TYPE=8260a-1.

If you now how to use fastboot could you post result of "fastboot -i 0x0502 oem device-infos" ?

This should mean that if I had the balls i could try this and it should work:                               
I'll first repair my ZTE Blade's digitizer this evening so I have a backup Phone in case it goes wrong ...

Is there a way to know the proc version before buying (like, for example, from serial number, or all S500 available now are  a-3 while a-1 was only the first selled units)?

I ask because the locked bootloader was the only thing preventing me to buy (well, that and the availability of an extended battery, from acer or any other supplier - still no luck on this one)...But it seems that depending on the proc version, some S500 can still be unlockable...

[paugustin]

No way to know. I thought the 8260-a1 was for the dual-carrier version that is sold in a few countries.

Hard to say. My CM had 8260a-1 before i brick it and goes to SAV, after they changed motherboard, it's now 8260a-3.

At the moment, we don't have a workaround for that.
