Hi
Ive had my phone on the Infusion rom now since november and its been ok ,
I want to try one of the JB roms now that ive seen on the site but im not sure on how much i have to do again as im already rooted and so on.
When i did it i followed the explained like your 5 tutorial which took me here http://huaweig300.co...m-from-scratch/
Can i just jump to step 7 of this tutorial that says install custom rom ?
As ive already rooted and done the clockwork mod thing,ive tried searching but the search function isnt great
cheers

If you have unlocked bootloader, you can just install rom. Try Slim v7 based android 4.2.2. Download rom , put on your SD card, go to clockwork mod,make wipe and install zip from SD card.

If you get random reboots when you are on 3G, then you should try officially unlocking your bootloader with the tutorial in my signature, as the unlocked bootloader can cause random restarts on 3G.

Hello. I have an S4 now, and I hardly ever use MoDaCo now. 

Therefore you will receive no replies to any PMs

Please post in the forum instead. You will get more help there :)

:excl:A WARNING TO ALL G300 OWNERS! Please Read! (The Flash Memory Problem!) :excl:

Tutorial: How To (Officially) Unlock Your Bootloader! (The long way, but which definitely works)

Please, Do not use the HuaweiG300.com Tutorial on how to unlock your bootloader, it is better to unlock it officially with my tutorial!

Spoiler

My Device:

Huawei Ascend G300 (U8815) - Sold!

Samsung Galaxy S4 (Black) - The LTE Version - GT-I9505

(Ignore the links above (if there is one). It's a skimwords (advertising) link and nothing to do with me!)

The ROMS I have used:

Spoiler

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!

Did I help you?

If I did, Please press the rep_up1.png button, in the bottom right hand corner of my posts.

(If not, Press it anyway!)

If I really helped you, you could also donate to me. Thanks!  :)

If you are rooted, and you have clockwork mod installed, I assume your boot loader is unlocked.

Continue these steps or follow the ones you are using on the guide.

Select a rom, download its required components such as the ROM itself, download the Google Apps.zip (gapps) provided in the thread, if needed.

Once your following downloads have been finished, transfer both files to your SD card, I recommend you place both files in the root of your SD card, so you don't have to navigate through folders finding the rom, and it'll avoid confusion.


Power off your device and remove your battery for ten or so seconds, re-insert the battery and boot into recovery mode with the following buttons.

Volume Up and Power, hold these buttons simultaneously until you boot into cwm.

I advise you do a backup of your current ROM in case something happens, though this is optional.

Once you have done the following, wipe cache, and factory reset the data.

Proceed to the installation of the ROM by selecting, choose .zip etc etc. Don't choose side load!

Select the ROM first and install it followed by the Google apps (gapps).


Once your installation process has completed, you will be brought back to the menu, continue by selecting reboot.

Your new ROM should boot.

Hope I helped buddy.

If you are on infusion, its certain that you are already unlocked. Now all you need to do is drop your chosen ROM on your SD card, do the correct wipes, and flash it. This is the standard with every ROM. just flash it, nothing else needs to be done e.g. unlocking the boot loader.

You do it through clockworkmod. Every ROM on the forum usually has the instructions on the opening post.
