Hello, first of all I'm sorry if its wrong topic but I dont know where to post.
I have few questions and I need help so I would be grateful if someone answers at least one question

- My G300 is rooter and bootloader unlocked, today  I installed  CM10 and then switched to CM9 but neither of them is fast enought, I mean, original rom that came with phone was faster (2.x.x?)
So,
1. is there a way to factory reset everything and then start from 0
2. is it normal to CM be slightly slower than orginal huawei rom
3. us there best rom? I mean fastes rom? Some people tell me to put orginal rom from huawei and put modded kernel (to optimaze ram and cpu) so is this true?

Thank you very much

My tuppence worth...

I am running CM10.0 (JB 4.1 based: http://en.wikipedia....F4.2_Jelly_Bean) and find it quite good. I haven't experienced some of the instability experienced by some others and I find it very quick. Can't compare it to stock GB (http://en.wikipedia....3.x_Gingerbread) or ICS (http://en.wikipedia...._Cream_Sandwich) because I didn't retain and play with them for long enough. I don't know if it matters but I think that my last official stock ICS was 936 (Vodafone Ireland) and when I installed Infusion and more recently CM10.0 I wiped absolutely everything. A totally clean install always seems to give a better chance of fewer problems as far as I can see!

Which is the best ROM is a subjective one. Some people have reported that the original (latest) stock Huawei (or carrier - e.g. Vodafone- variant) GB ROM is the most stable and responsive. Others prefer some of the stock ROMs (in particular CM10.0 and Infusion) even if they can have some issues. Personally I'm still inclined to stick with CM10.0 as I haven't had any showstopper issues with it so far and am still on R1.

However if you DO want to roll back to stock GB then you need to be careful as the downgrade from ICS does require some special steps. There are guides out there such as this one:

that you should familiarise yourself with and be sure that you understand all of the steps. Section 6 in particular. This thread is also useful as it has a lot of links to different resources:

If you are in doubt about anything ask first!

Hope this helps. Others (particularly more established posters than me! ) may have more/better advice for you.

dalyer thank you very much for your answer
I have tryed downgrading to GB but I fail at one of the first steps - backuping and restoring fake IMEI - after I backup my IMEI and save it somewhere else and put fake IMEI on sd, restore never gets my IMEI to 0, i tried many times but no luck, so if I cant restore fake IMEI then probably I cant restore my original IMEI later so I really dont want to risk it.
If anyone has solution for my problem I would be very grateful

[dalyer]

Sorry - I've never done it myself so can't really say what the problem is. Perhaps some of the info here might help? In particular maybe the Huawei official downgrade approach might work?

I tried official downgrade too but It fails every time , really dont know why because I read all instructions and I met al requirument (b937..)
The biggest problem is that no one on this forum has solution, you are the first person who ever answered me, so I got 0 support

[dalyer]

Look on the bright side - you haven't bricked it - yet!

Would this be of any use?

[Aceion]

I almost did when flashed GB rom - no IMEI, baseband was unknown and no mobile network but I managed to fix it by just flashing ICS again

No use of that, my IMEI is not changing, I think its my biggest problem

[dalyer]

Would this approach to zeroing the IMEI work?

http://www.modaco.co...em/page__st__40

Presumably you are rooted etc. if you have gone through this stuff before?

Edit: yet another thread in case you haven't seen it already and it helps...

I think I tried all methods for zero-ing IMEI but it just wont work. I searched forum and people had some simillar problems like me but they didnt get any answer too

I very appreciate your help!

So I wanted to unlock my phone to go from Vodafone to GiffGaff, I bought the phone from a Vodafone shop so obviously its locked. Now I've got an unlock code so I put the GiffGaff sim in and try to dial the unlock code but I cant because I have no service, any idea what im missing/ doing wrong?

You can unlock your phone even with another sim card which has service over there.And try the unlock code.

Hey I'm in a very similar situation, I need to restore to an original Vodafone branded ROM in order to unlock my phone and I appreciate the help you guys are giving. If I have no data or apps I'm concerned about preserving do I need to go through the IMEI zeroing process in your link? Or is it possible to simply find a Vodafone ROM and flash it through the recovery menu?

[dalyer]

What ROM/baseband are you on now? Do you know what your last official ROM was? If necessary the IMEI SV can be checked.

Hello
I think that this is best topic for this question..

I downloaded this package from Huawei site: http://www.huaweidev...softid=NDcwMjk=
In readme PDF file they wrote:

Quote

1.1 The following versions can be upgraded:
U8815 V100R001C00B934
U8815 V100R001C00B937
U8815 V100R001C00B939
U8815 V100R001C00B944
U8815 V100R001C00B946
U8815 V100R001C00B948
U8815 V100R001C00B951
U8815 V100R001C00B952

but I have U8815 V100R001C09B944. Can I use this package to update OS? I would flash custom ROM, but it's little different here than it was on my previous phone (LG P500)

Hi all, I have a problem I can not solve in practice the phone when it turn restarts

continuously huawei logo appears for 2 seconds and restarts continuously endlessly

repeating this sequence, I have to remove the battery to turn it off, does not enter
in cwm and even in bootloader.
When I connect it to the PC via USB cable does not recognize the drivers while installing

them.
I did not install any firmware method makes power up + down, it is a narrow bar and
stops at the beginning.

latest firmware gb

Help me please.

If you are on GB then I presume that your baseband is 109808. You might need to get a stock GB update.app and flash it. Copy it to your sdcard /dload/update.app and then boot into the stock update recovery/utility (think you press vol up, vol down and power together and hold for a few seconds).

Hi, I have done this test but nothing to make you start getting close and the progress bar stops almost at the beginning.
Maybe the file Update.app that I have is wrong, someone can link to where to find the file.

thanks in advance.
