I have a G300 with ICS Vodafone 4.0.3 B952, but cannot make it happen. Followed the guide step by step, even downloaded the HuaweiWinHandSet, still no joy, I'm using Win7.

What I did is:

Turn on USB debugging,
Connect phone to PC
Run Root.exe
...at the end it says "Root Failure, Check Drivers"

I tried to do this in bootloader mod, holding volume down and powering up, then it says cannot find device.
I read the cmd while it was running, was things like "more than one device or emulator"

If I connect it (just plug it in) I have in MyComputer a 3G Mobile, and 2 empty hard disks. if I select connection type multimedia device, instead of the previous three I have Huawei8815 or something, either way doesn't work.

I found another guide where you have to download the drivers and an .exe called RootG300, but cannot download, says "Network Error"

Any help would be appreciated, maybe I overlooked something, but I've been trying to root my phone now for a half day, and really wish to make it done.

Thank you

Regards,
Velgdran

Just a quick update, when cmd is running the last 3 phrases say: " Unable to chmod system/data/xbin/su - No such file or directory" if it helps

There are some reports of the cm10.1 ROM unlocking network Sim locked phones. Look it up on modaco g300 forum.

Since the ICS update the device no longer supports 720p recording

Exclamation I accendatily deleted my contacts both from sim and from gmail...help....!!!
Hi everyone,

last night i was initializing a huawei ascend g300 by inserting a sim card which has 175 contacts in its list.....i went ahead an synchronised first the phone with the gmail account throught wifi but had diabled auto-sync and back ground applications too....then went ahead and copied all those contacts to the gmail account by manage contacts>copy contacts>sim to gmail account and after that there were two contacts each name appearing hence thought i would delete and copy it once again from sim card hence i deleted all the contacts.

After deleting the contacts it came to my attention that i had accidentally deleted sim contacts along with the contacts which i had copied to gmail.All i needed to do is go into view setting and uncheck the sim and the phone such that only the gmail contact would be displayed.


I already tried the restoring of contacts from gmail account as the auto sync was disabled hence no contact was synchronised on the gmail servers


The phone itself is new hence i dint took the back up so that option aswell seems to be out of context now......

I am having the sim card data recovery software but do not have a sim card reader currently in search of it..will keep you posted furthur.

Isnt there anyway of using the phone as a sim card reader...or the sim slot at the back of lappy....as the sim card reader..?

I want to restore those contacts is there any way around it.....?

Any suggestion...advice would be immensly appreciated coz im in deep trouble...

Ask Google if they can roll back your account to before you deleted contacts.
