Hello everyone,

I was very curious to know what kind of memory I have but when I enter this (cat /sys/class/block/mmcblk0/device/name) command line I get that it is not found. This is strange because when I type su and press enter it says superuser rights granted. I'm using atomicmod ROM running 2030 baseband.

Don't use brackets!

Try downloading an app called file manager from the play store, go settings, tick root explorer, grant SU, then mount system. Now press up until there is a single / at the top. Then go sys > class > block > mmcblk0 > device > name. open it, press text then open it with a text editor. If it says access denied or cant find file just press back and use a different editor. You will also probably have to grant SU to the text editor. Dont worry - its fine

Commiserations to al the people who have hynix :(

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

My Device:

Huawei Ascend G300 (U8815) - Sold!

The ROMS I have used:

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!

Almost certainly nothing to do with the Hynix eMMC issue.

Hynix strikes!

 

Went to sleep last night after reading a book on my G300. Woke up this morning and it was completely dead.

 

Well, almost. If I plug it into my Linux computer I see log entries showing that a USB device has been connected. But that's it.

 

Deliberately didn't upgrade past 10.1 due to the warnings. 'Phone bought in the UK (Ipswich) round about October 2012.

 

So my planned upgrade to a Moto G happened rather sooner than expected. G300 will go back to Huawei for a warranty fix - always good to have a spare (and something to test apps on).

Are you saying that you checked before this and it definitely had Hynix eMMC?

Same thing as happened to poster 'Beermad' happened to me. Went to bed, left phone on, next morning dead as a dodo. Would not respond to anything. Was running cwm11, but do not know what chip it was using (well, I did, but I forgot). Returned it to Huawei and five days later phone returned to me in working order. No queries on their part - the phone was well over a year old.

Created an account on Modaco especially to post my findings for you. But I guess its useful to have an account anyway as its a good forum :)

 

But.... unfortunately bad news for me....

 

I have Hynix memory.

Date: 06/2012

Purchased in: UK, from a Vodafone store.

 

Now what will this mean, and what can I do about it?

Do I have grounds to send it to Huawei straight away to get Samsung memory?

 

Also, now that I have unlocked and rooted, does that mean warranty is invalid and thus Huawei will just say tough luck?

 

I read that if you have Hynix memory, I should install CWM 5.0.2.8 instead of the latest version. Is that correct?

And does this limit my choice of roms? Im not sure how different versions of CWM and mods are affected by memory, surely it just means you can use anything, but its just going to be unreliable in general? Or do later version of things cause strain on things? If someone could educate me on this, I would appreciate it.

 

I was planning to install either Stock+ or Slim roms, probably most likely Stock+. Any thoughts anyone?

 

Thanks

The Hynix situation is not that clear.

My impression from the anecdotal reports here is that they may be in danger of bricking spontaneously no matter what you run on them.

However it seems that ROMs/CWMs based on the 3.4 Linux kernel might be particularly dangerous to them and cause or expedite bricking.

So steer clear of them.

But at least one person has recently bricked a Hynix G300 while NOT running anything with the 3.4 kernel.

If you want to run GB (and personally I think it's the best choice of Android for this phone) then you should try GBXTREME as it seems to be the best GB ROM around right now.

If the phone is in warranty then one option is to deliberately brick it sooner rather than later, take it back and hopefully get a non Hynix replacement! :D

I think george109 may have something that will deliberately brick Hynix G300s. Check earlier in this thread.
