If it still does not work after this, follow this


You will need CWM recovery to be able to update, If you don't have it, follow this post to get it. Now, Chris Wyatt, has reported that if you flash an ICS repack withComplete wipes - Go into mounts and storage in CWM, then wipe everything except:
/sdcard
/
sdcard0
/sdcard1
/sd-extNow you have flashed the repack, you will have to go to the CWM home, then go to advanced > reboot recovery. Now wait until it reboots and then flash the relock bootloader zip by jsevi83. Then you can carry on with the tutorial, by following the next post.

Do this. DO NOT CHANGE YOUR IMEI!

Download Blink, a great app that controls the status LED on the G300!

Wait for 5 seconds and then click skip ad! Do not download anything in the ad window, that is not the app!

Thank you george and dalyer for helping me :) .
Does it matter which link of ics repack 1 or 2 or probably will be the same if I flash ICS repack worldwide release relock bootloader and after that carry on with the tutorial?

Well it depends.
The SD card set as default will mean that whenever you install apps, they will go to the SD card. If you dont use the SD card, then i would flash the normal one.
It doesnt matter which one you flash at all, they all contain ICS :)
Then flash the relock bootloader zip and carry on :)

My suggestions ... make sure that you are putting dload/update.app in the root of the external sdcard and not the internal "sdcard".
Also try another sdcard if possible - some people had problems using one when another worked OK - for no obvious reason.
Try the B952 general version (here from Huawei http://www.huaweidev...softid=NDcwMjk= or in the original post of this thread as a split zip) again.
If necessary try the relevant "middle" file again.
I would strongly urge you NOT to mess with the IMEI if at all possible so exhaust all other possibilities first.
Others may have additional or different advice....

Hope this helps and you get sorted soon.


I've tried all of this...formatting my sd card also and tried again, tried with general version from huawei..middle package, and nothing seems to work. I didn't try with different sd card, but I will try that also and see

I assume that you are in Croatia, I will try to find an update.app for you. but first, where did you get your G300 from?

Jep...Croatia. I've bought the phone from the carrier called bon-bon (if this means anything to you?), and officially phone was on GB locked on that network, but after official update to ics the phone was network unlocked.

Don't worry, when I was new, I really worried about bricking my G300 as well! Now I don't worry as much as you cannot brick this phone, unless you do one (or more) of these things:
1. Alter your IMEI - as this changes MAC addresses
2. Take the battery out when you are doing an update.app
3. Break it physically!
You should see what I put my g300 through! one example is overclocking it(I think the devs were shocked when I said that I had been running my phone for 2 months with the minimum CPU speed at 1113 mhz and the max at 1113 (as that as fast as it will go before it freezes up or reboots! :P)
Everybody has to start somewhere, I also used to ask a lot of questions when I was new as well! :)

Sorry, but I can't find anything for a Croatia update.app :( so I would recommend using the ics repack and bootloader zip,

I know it's not Croatian but would the Serbia Telekom B952 update.app be of any use?

Thx but update.app do not go on my case, so I will try with zip files

Ok. Good luck
Remember, you can't do this on the stock recovery. You will need CWM or TWRP recovery for the zip files...

In mounts and storage I have options to format: cache, cust, data, system, emmc, sdcard.
As I understand i need format everything except sdcard in my case...right?
I google it format/emmc and the people don't advise to format that.
