Huawei Ascend G500 Pro / U8836D

[Guest adrenalize_]

Hi,

I've got hold of a Huawei Ascend G500 Pro otherwise known as the U8836D.

I'm kind of a dual sim fan and have tried the HTC Desire V /T328W which would be great if it wasn't so slow!

I kind of liked the idea as it is a dual core, front camera and larger battery than the Acer Liquid Gallant Duo, although it lacks the compass.

Of course it was released in China - but has a almost stock version of ICS 4.04 with English as standard, but no Google framework/apps/play store although it is on the Google play list of devices.

I have tried the Bin4ry root method - which appears to work - but when I run root explorer it says it does not have superuser rights!

Has anyone else got one or any tips/ideas for getting root? I would like to try putting the Google framework stuff on to it

I know a certain supplier in China will eventually develop a ROM and root etc but I would like to add the google stuff to the pretty much stock rom.

Although I've used android for a while and used to IT I'm pretty new to modding so treat me gently!!

Just to be sure - do you have Superuser or SuperSU installed

Hi, Thanks for the reply.

I tried the Bin4ry v2 and v8 versions and they installed the Superuser app.

I've just noticed and tried Bin4ry's v10 version and that has updated su versions and SuperSU and I now have root!

Yeah! - so now I'm off to look at a complete backup then to install the Google services and Apps (especially sync (contacts calendar) gmail and play store.

Again any tips welcome - feeling my way slowly!

The handset is very similar I think to the Acer Gallant Duo/Solo as it uses the dual core Mediatek chip. I'd imagine the Mediatek flashing tool will work just fine - but obviously we need a scatter file for the G500. Anyone have any tips on how to create one - can it be done by reading the device with the flashing tool? Can I backup the entire device with the flashing tool?

The drivers with the mediatek flashing tools for the Acer Gallant seem to work just fine with the G500.

I might do a mini review as well if anyone is interested - would be better if I got the google stuff on first. I'm not so sure there will be that much interest and warrant it's own forum so I'll just update this thread for the moment.

[Guest adrenalize_]

Hmm,

So I've got an adb shell to my G500 and was thinking of following this guide to create a scatter file http://bm-smartphone-reviews.blogspot.co.uk/2012/04/creating-rom-dump-of-your-mt65x3-device.html?m=1

However when I do a cat /proc/mnt I do not get any mount points at all! I get the first line:

cat /proc/mtd

dev: size erasesize name

shell@android:/ $

Has anyone got any ideas where the mount points may be on my device?

[Guest adrenalize_]

Hmm - seems that the G500 /proc/mtd is not used but /proc/emmc is used instead. It doesn't seem to list the same areas of storage as the /proc/mtd and is similar to the Lenovo A750. On another forum someone mentions this and I think they just waited for an official/leaked update to get a scatter file.

As it looks like this option might be out - is there another good way of getting a conmplete image/backup of everything?? Maybe using dd in an adb shell?

[Guest adrenalize_]

Found a bit more if anyone is interested.

The Mediatek engineers mode can be entered by typing this in the dialler * # * # 3646633 # * # *

WARNING! Enter this menu at your own risk. I do not recommend changing anything in the menus.

Under the "Memory" section you can see the partition list that seems to contain the info that might be useful in creating a scatter file, mine is as follows:

StartAddr:

Start Address of partition;

Hopefully this is a good step towards the scatter file - will look into it more when I have time.

hi, just come across from google.

just want to give a little help.

i have different MT6577 device with working scatter file.

you can read my scatter file and my memory info screenshots.

i've read your memory info, it is different starting from "android" partition up to end.

if i understand correctly, you must add "600000" to "starting address" using Hex calculator to android partition up to end and edit my scatter file accordingly.

and you may need SP flash tool and vcom usb driver here (but dont flash my boot.img) http://www.mediafire...qk7513ghfzlnaax

You can make a scatter file using the partition list, this is what I did on the Gallant Duo. :)

Hi,

I have G500, but anything went wrong with my ROM, does anybody have backup ROM, so I can recover my phone back. Thank you for help.

[Guest adrenalize_]

Thanks Paul and tri_zet for your help. I've managed to make a scatter file and dump the entire ROM for safe keeping, and added gapps.

Yes the addresses are straight absolute addresses in the emmc not relative to the partitions. When I have a few mins I'll post the file and a few links/instructions for anyone interested.

neveceral - so yes I have a dump of the rom and will post links instructions for you to make a dump - or ask me if you need any partitions already! I guess at some point someone may get hold of the official factory ROM.

I notice a dev with quite a bit of experience in MediaTek phones has got one and produced a CWM recovery, and is likely to post a ROM shortly - over on XDA and I'm sure a quick Google will get you there!

I purchased a Huawei 510 from ebay and after spending a day on trying to install Google Play on it I have been told that its actually a Mediatek devie.

1. I have no Google Play Store
   
2. I cannot install it with an .apk
   
3. I cannot put the phone in fastboot mode
   
4. I cannot find the windows drivers for it, I have searched, googled and tried a whole bunch of 65** drivers but these are the errors I get!
   
   

I downloaded the exe files and it extracted to C:\Program Files\Handset WinDriver

Gave the path for updated drivers and it says that best driver is already installed
