Hi guys

I have a G300+ which I attempted to root to install a custom rom. I followed the directions on http://huaweig300.com and managed to get to http://huaweig300.co...rkmod-recovery/ before bricking my phone. The brick occurred after running "BootloaderG300.exe".

It appears I have exactly the same issue as this guy: http://www.modaco.co...oot-whatsoever/
Same symptoms and everything.

I would like to confirm, is the G300+ actually supported by this unlock bootloader method? If not, what can we use?


Thanks for your help

Does it turn on at all? Also I would of used the official way to unlock the boot loader. Did you use the right Bootloader.exe because there is two of them one for baseband 2030 and 19808.

There's no bootloader.exe for 109808 because on GB and "old baseband" bootloader is not locked... Is g300+ same as g300?

The difference between the G300 and the G300+ is that the G300+ supports more frequencies (HSPA 850/900/2100, GSM 850/900/1800/1900)
That's the only difference I'm aware of.

I upgraded to 2030 baseband before attempting to unlock bootloader. I used the file found at http://huaweimobile....t/mobile-phones under G300+

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!  :)

Did you just get the firmware file from that Aussie site? Did the phone work after that? are you in Aussie? is it an Aussie phone? Basebands and bootloaders are complex things and are coded only for one phone. I would get the correct firmware from your phone provider, put the dload file on your sd card, plug the phone in with the battery out and try start it using the volume down and power combo (I think, it may be volume up or volume up and down at the same time.)

You should attempt to unlock bootloader of your phone by using this method here - link , code is generated for free, then only procedure from cmd window is left.
