Well here is the update:

I don't know how but I managed to flash the rom - the Chinese language is now gone and also the status of the reception where it shows 2G is now green instead of blue like before.

As for the 3G option, I don't have that. In your picture you uploaded it shows 3G, mine only shows Network Mode - GSM only. I also cannot change that. It is available to change but when selecting WCDMA, I go out the screen and come back and it is back to GSM.

I also did the ping test like you but it only shows EDGE.

As for AT&T - They do have it in my area but I don't know of anyone to test their sim.

As for trying another rom - I would not know where to get one from so if you have any ideas, let me know.

Edit - another change is now my camera does not have the zoom feature like it did before - everything works fine, camera and video are good but no zoom

Thanks again for your help.

when u get this error ?

turn on ur phone and enable usb debugging and unknown sources .. and connect the usb cable to pc and phone .. then click on the root button on mtkdroid .. dont touch ur phone in the entire process except when it prompts u to clear data or reset .. after that leave then phone .. let the tool do its work .. after u make backup u restart the phone .. it will be again as it was .. the root which u get when u click in mtk droid root tools is called a shell root .. its not normal root .. and this tool gains only temporary shell root .. and when u restart the phone its lost .. and when it is temporarily shell rooted u will get this error .. but the moment u restart it u wont get this error .. it is only temporary ..dont worry about it . the key is to get a working backup .. with 0 error .. u should take at least two backups .. and each should succeed without any error ..

after the first backup finishes .. again click the backup to make another backup copy .. dont restart the device and re do all the above steps .. just do the backup .. by clicking the backup button .. that is called killing two birds with one bullet.

and do i need to tell u again that do not flash dsp_bl and preloader ?

sometimes there is the 3g icon but as i mentioned that there is no 3g in my area/country .. so its some error or infact one of my older device which i do not remember which one it was would show 3g when there were no signals .. LOL .. however i do see the wcdma mode and when i select it it then reverts back to gsm only ..

also is wcdma different thing then 3g ?
[Android Q&A, Help & Troubleshooting] khankll:
i clearly mentioned that mtkdroid tools is not to flash a rom onto phone .. its to obtain a backup of phone and make that bacup ready for flash with another program called sp flash tool ..

for flashing u need another program called SP Flash Tool .. and do not flash dsp_bl or preloader ..

Flash new rom or factory reset?? I guess u might get mix up?:confused:

The 2g symbol background color can be changed in Setting > Sim Management

You have to insert a proper sim which runs freq. bands of 850 or 2100 and set up an APN, then the menu of 3G option will appear.

Similar to WCDMA choice and run ping test (HSPA), u need the above sim inserted to the slot to work out.

I repeat again your Simple Mobile sim will never get 3G in this device as they talk different freq. bands in the network...

Unless u put in the right freq. sim, u will not get any 3G service menu, WCDMA setting nor 3G icon on top of home screen..:confused:

As for rom matter, better consult with KK, I am sure he can help u out.

---------- Post added at 05:32 PM ---------- Previous post was at 05:15 PM ----------

wcdma mode is selectable only when a 3g sim of 850 or 2100 freq. band inserted to the device,

similar to 3G Service menu will appear after device has detected the 3G sim and APN setting

3G icon will be shown after 3G data connection get connected to its network.

WCDMA (or Wideband CDMA) is a technological term used to describe so called '3G' cellular services.

U have to google out for deeper technical details...:)

The phone was definitely flashed - not factory reset..

As for the fequency bands, I checked simple mobile's website, they say that they run the same frequency as T-mobile - "Only phones with 1700/2100 AWS band work on our 3G network"

I also know that simple mobile offer HSPA as my brother has a nexus i9250 on their network and gets HSPA speed.

So perhaps it is the firmware on the phone that won't allow the 3G speed, or perhaps it is the hardware on this model - don't know.

---------- Post added at 09:46 AM ---------- Previous post was at 09:36 AM ----------

Yes I made a backup - thanks.

One question though - with regards to the antenna you made, can you please explain what it looks like?

Did you take the 2"-3" wire and just run it straight along the existing antenna, or did you curve it round like:

_ ___ _ __ _ ___

|_| |_| |_| |_| |_| |_|

---------- Post added at 10:15 AM ---------- Previous post was at 09:46 AM ----------

One more thing I noticed with the new rom - when I tested the camera, I noticed there was no zoom, so I installed another camera from the play store, however when trying to take a picture, the image is upside down. I thought perhaps it was the camera so I installed another app and same thing - weird.

Though Simple Mobile operates both 1700/2100, but for 3G (wcdma or hspa), they run only at 1700Mhz band, not at 2100Mhz band.

http://www.howardforums.com/showthread.php/1761622-AT-amp-T-T-Mobile-3G-frequency-bands

This S3 is a Chinese clone version support 3G (WCDMA) with 850 or 2100 freq. bands

Both the firmware and hardware (Radio transmission) do support 3G, but at the above freq. bands

Your brother's Nexus gets 3G (HSPA) speed because his phone support 1700Mhz band.

Thoroughly read the above officail Simple Mobile web links pls? :confused:

all after market apps give inverted view finder .. this issue is still lingering ..

try ucam thats nice app and doesnt gives the inverted view .. the only app that i found among dozenssssssssss of apps..

it also has nice macro mode .. which is awesome .. gives much better focus then stock ..

regarding the antenna .. the zigzag line is just for illustrations .. the real gps antenna is as i posted above ..open that pic ..

i just scrapted a part of it and used aluminum tape on it to stick the ide cable single strand to it .. and ran that straight accross the body of the device .. i didnt followed any specific pattern in laying that ..

but i am very disappointed with its gps .. the best accuracy that i get wit it is 25 meters .. (in city streets) and at the same place samsung galaxy mini gives 4meters accuracy .. and gets locked pretty quickly as well ..
[Android Q&A, Help & Troubleshooting] kouger1:
Well I decided to mess with my phone again. I opened it up and took some of the wire from the ribbon cable - single strands and solder them onto the contacts where the taped antenna go. I then closed the backing and ran it along the length of the phone. GPS was in view but no signal strength. Then as a test I took a solid piece of copper wire, quite thick, and attached it to the thin ribbon wire and low and behold, strong signal lock. Removed the thick wire and lost signal. Then I touched the thin wire and signal lock again.

So now I have to figure out how to get a signal lock without that thick wire.

Updates to follow

Edit - I downloaded that app - ucam - it is awsome - thanks
[Android Q&A, Help & Troubleshooting] khankll:
Another thing which I noticed is that in balcony there is 3-4 meter long telephone wire which is very thick which is actually there to hang clothes in the sun to dry them. When I just place my device against it I immediately get locked in satellite.

Also when I put the phone on the fuel tank of my bike I get similar results. I noted it one day when I was put it on my bike when I was standing beside it.

Also if I put the phone in a metal big sized saucer I get awesome signals.
[Android Q&A, Help & Troubleshooting] kouger1:
I too get great signal if I place the phone on the hood of my car - or even a piece of tin foil - solution, make a glove out of tin foil :)

So what I discovered last night was that if I have a piece of wire, (I used one from a headhpone) and run it the length of the phone and have it sticking out a little, I get very good signal and lock on in a few mili seconds. Now I just have to figure out how to place the wire inside the phone.

The problem is the minute I cut the wire to the length of the phone or curl it up inside the phone, I get a weaker signal. Have to find a good piece of wire to use so that I can place it in the phone and still get good signal.

[Android Q&A, Help & Troubleshooting] amyren:
I had a completely dead phone after a failed flash once.

Be sure you have all the needed drivers on your pc. If you already used the SP Flash tool once, the drivers should be ok.

- Remove the usb cable from your phone and remove the battery

- Use the SP Flash tool and open the scatter file for the the rom you want to flash, then press the download button. (the flash tool should start searching for your device)

- Insert the battery, do not turn on the phone. Then connect the USB cable to your PC.

- If nothing happens, try to disconnect your phone and try again
[Android Q&A, Help & Troubleshooting] amyren:
Any updates on this, and maybe some pictures, so that we can see exactly where the wire is connected?

When you curl up the wire inside, the signal gets weaker you say. How much weaker would you say, same as no wire at all or is it any improvement at all?

Btw, did you try the app GPS Booster?

For me it did improve the signal (from no signal to weak signal). The app does report an error (gps booster failed) but does still seem to work.

In the same thread you will find several links to roms to flash directly from phone with cwm recovery.

I find the rom named 4.1.9 was the best so far for my phone. ( you will find a link for that at page 16 )

---------- Post added at 11:37 AM ---------- Previous post was at 11:35 AM ----------

I have never tried that rom myself, but did search google for that rom file name, and it looks like the link is here:

http://narod.ru/disk/65034915001.90...GT-I9300_121010_backup_130101-155525.zip.html

It says that you need MTK Droid tool to prepare it for flashing...

**

Edit: some more info and questions about the firmware

**

I did download that archive myself to take a look at it

There are two tools I know about that can be used to load a firmware.info file and generate a scatter file, MTKDroidTools and MTK_Rom_Studio.

I did try both and both work fine to create the MT6575_Android_scatter_emmc.txt

Note that you must make sure you have recent versions of these programs, or they might not work properly. I was a bit confused myself at first when downloading these tools and it turned out they was to old to support the MT6775 cpu.

Versions of the working software I tested: SP Flash Tool v3.1238.5, MTKDroidTool_v228 MTK_Rom_Studio available, v1.1.77.301

Note that this archive is not a full backup, as the preloader.bin is missing. But it still should be safe to flash to test I think.

Thanks for your reply, i tried this rom and so far seems to work fine as compared to v26 version... No major issues in this, just the problem which is annoying is camera is upside down in some apps. Also does our phone supports 3G? In sim management nothing i can select other than GSM only..... While 3G works fine if i insert the same sim card in my other handset.

What rom are you referering to that you tried, the 4.1.9 that I mentioned in my post or the one linked to at that russian website?

At least the 4.1.9 version I beleive that 3G is working. I dont have 3G at home, so I only breifly tried the phone at an airport last week and I think I was using 3G then. (on the Lewa rom I got no data connection, so I flashed the 4.1.9 rom at the airport to get on the internet).

But I think that only one of the sim slots does support 3G. So the regular SIM slot will not have 3G, but the micro SIM slot does support it. Havent tested it, but I have read it somewhere.

Also using the micro sim It only shows E and when I set the data connection to WCDMA after a few minutes it will revert itselft back to GS</WCDMA but can only pick up GSM network. I know WCDMA is available in my area as I have Karbonn A30 and it picks up WCDMA with no problem.

Please upload the LEW OS rom microsim can only pickup the GSM signal no 3G nor WCDMA. Hopefully LEWA OS can fix this problem. The problem when making calls like dialing a number would make the screen go black and when pressing the power button/home button it will only light up for a few minutes then the screen goes black again only solution is to turn off the phone completely by removing the battery and turning it on again.
