i have noticed that my device was not able to get 3g or hspda data connection.. im always having EDGE connection .. eventhough im on a 3g/hspda coverage area.. does this mean that my device is not 3g/hspda capable?
[Android Q&A, Help & Troubleshooting] khankll:
i dont think its 3g .. as i found on one italian forum as well ..

also when i looked in the engineer menu for frequency bands .. the wcdma band frequencies were greyed out .. only gsm were there.. so i could infer from it that it might not support 3g.
[Android Q&A, Help & Troubleshooting] khankll:
also what battery to use in it ?

hi,

I got an exact clone (dual sim) and similar issues as yours.

Despite the weak signal gps, inflated storage size (x8) and stock camera resolution etc,

most other features (if not all) are working properly on my current stock rom.

Also the device was rooted the same method (hearty thanks to Bin4ry).

The only problem is: I can't install any CWM to this stock rom? :confused:

Including yours (mediafire.com/?acbbhu7lq1lrq8v from post #35),

I could successfully flash it with spf tool v3.1224.01,

but could only boot to 3e stock recovery, not CWM? :confused:

Flashing a new rom especially yours might work?

but I want to stick to my current stock rom as the gps+storage+cam resolution issues are not a big problem to me,

So hopefully you or someone can help me out.

**My Device Kernel version: 3.0.13 - 1211 V41 - Mon Nov 19 17:14:18 CST 2012

By the way, my device functions properly on 3g data connection. :good:

This S3 clone mt6575 supports 3g frequency bands of 850/2100 MHz.

Only sim with the above 3g freq bands will work in this handset, otherwise u will get only 2g.

So insert a proper sim, enable 3G service in Settings > Sim management,

then add New APN in Settings > More... > Mobile networks > Access Point Names >

(your sim) > phone menu (left side next to the middle home botton) > New APN

after fill in the access point setting info (obtain from your sim operator) > press phone menu again > and select save.

hope it is informative and helpful more or less... :)

care to share your current rom?

downloaded and tried the attachments in your post,

it seems to me not the ones your referring to in your "edits'.

Your attach backup files are the only ones working on my s3 clone

and I've tried every roms out there mentioned in the other thread.

thanks.

I have uploaded the current rom. It's In first post. Also I uploaded Cwm recovery image but it seems that the link that I have shared above is for stock recovery. As per the experience of hhsgw. . so i have uploaded the cwm agian .. please verify which one is which one .. i.e. the one posted in first post is stock or cwm ? ( sorry it certainly seems that i have mixed up things) .. this link below is definitly cwm from my device .. hope it works with u as well..

http://www.mediafire.com/?ze0dt144op95rca

Bro camera issue is nasty. With new rom my camera colour and focus has improved a lot plus now i can record video in 720p. Earlier I could only in 240p

Also the chip set supports 3g but the manufacturer has not used that feature.. also here is no 3g service .. we are just 2g .. so no worries

i just want my compass to work correctly:mad:
[Android Q&A, Help & Troubleshooting] janhenz:
thanks,

i will download same file again. I must have mix up some files.

The first time i flashed it, some things things were working and fixed - 720p recording, GPS satellites detection

though i still had to flash gapp new talk for GoogleTalk to function.

But then after trying out other roms and then reverting to your rom, i don't get the same fix anymore. :(

The recovery image on first post is CWMR touch v5.5.04

but it doesn't function well at my end. it gets stuck when i try to do backup.

will try from your new link.

thanks

btw, I have no single IMEI problem such as yours

the rest however we bear the same issues.
[Android Q&A, Help & Troubleshooting] khankll:
same here . but dont expect any solution..

though some ppl say there is no real sensor for compass in it .. and its dummy values which are taken from other sensor and manipulated in the kernel and puted to user which is why we get wrong values .

also most ppl using chinese claim to have this issue .

@janhanz

well is urs kernel version 1212 or 1211 ? can u post the two screen shots one from the factory mode and one from the andorid system about phone ?

Wow! yr new rom camera performance sound convincing, I may try it soon,

btw, increasing performance on stock cam or UCam or on both?

Now let me try yr new CWM upload, hopefully it will work this time. :)
[Android Q&A, Help & Troubleshooting] khankll:
if it doesnt works then i will sew one for you ..

just upload your working stock recovery .. i will sew some variant of cwm ..

the performance of camera is in stock .. earlier i could obtain 8mp only in ucam . but that was not so good .. and though i could record 720p video on ucam but fps were 10-12 .. and with 480p 14-15fps .. i couldnt find any way to increase that . .

now with stock rom i get 720p with 29fps .. thats awesoeme .. but file size is hugggggggggggge.

also i still have one nasty issue .. that in many aftermrket apps that use camera like qr code scanners or barcode readers i get the camera viewfinder inverted .. rotating camera and disabling the autorotation does nothing ..

also on stock camera app when i reduce the video qualtiy i can record in 480p but the fps are a megre 14 fps .. ucam has same issues as i faced earlier ..

before any adventure have a backup of your rom ..

[Android Q&A, Help & Troubleshooting] khankll:
i used that rom and am using that one ..

same version as u mentioned above ..

i first flashed it .. except its dsp_bl and preloader .. so yes u r right in saying that the one which i uploaded is not exactly same as that one . as i had working dsp_bl and preloader so no need to experiment with it .. thats why i left it out when flashing that rom .

after flashing it and testing it i permenantly shell rooted it .. these are the two differences b/w the one which i uploaded and one which u downloaded from that russian forum link. i shell rooted it because i will be frequently taking backups and dont like the always rooting method .

Your 1st post about phone screenshot version is 1212 V26

or was that your previous stock rom screenshot? :confused:

Anyway, is the new uploaded custom rom version 1212 V16?

And it included:-

1. Permanent shell root

2. A working CWM

3. Updated GApps including G-talk

4. And those fixes u mentioned in ur "edit"? :good:
[Android Q&A, Help & Troubleshooting] khankll:
the answer to both questions is yes.

u figured it correctly..

in the pic its 1212 v26 which was my original stock and it had tons of problems that prompted me for this very post ..

the one which i shared is 1212 v16 and has solved most of issues as explained in the edits .. in the issues .. on first post ..

1. Permanent shell root Yes so you can frequently take backups using mtkdroid root tools without rooting it first every time u take backup( its also rooted .. )

2. A working CWM yes

3. Updated GApps including G-talk yes (and i forgot mentioning it .. considering it an intergral part of andorid )

4. And those fixes u mentioned in ur "edit"? :good:[/QUOTE] (yes .. few minor still exist .. like inverted camera view finder in few apps .. still figuring which qr reader / bar code scanner would not give inverted view .. so that i can easily read them .. also compasss issue still there .. gps signal weak but thats hardware issue as placing the device near a long copper wire immediatly catches gps signals .

pardon my confusion,

i have downloaded that mediafire ROM about 5 times and flashed it about 5 times

and it's not v16 but v26.
[Android Q&A, Help & Troubleshooting] khankll:
Which files u flashed?

Is it working for u?

What issues are you facing in it?
[Android Q&A, Help & Troubleshooting] janhenz:
your uploaded custom rom. It's not version 16.

it's the very same rom w/c came shipped with the device.

The problems therefore remain as it is.

there must be some mix-up or something.

I manage to flash v16 thru the backup zip file from the Russian forum.
[Android Q&A, Help & Troubleshooting] khankll:
i asked which which files of my uploaded rom u burned ?

it should be the 1212 v16 .. i dont know how it happened ?

also i m dam sure it is 1212 v16 .. not v26 .

howerer it is esserntially the same rom as that russian forum one which u burned and it solved most of my problems.

only diff b/w russian is the preloader and dsp_bl ..

the one which i uploaded does not have these files from that russian rom .. but from my stock rom ..

i am shocked at the perplexity of these files .. :confused:
[Android Q&A, Help & Troubleshooting] kouger1:
Hi.

So sorry for the delay. Has been crazy couple of weeks and not had the chance to do anything.

I am going to try and attach the pictures of what I did but just in case, I will explain as well.

Firstly I am not sure if this is working or not as I had made the modifications and it seemed to work, then the following day, I lost GPS signal again. Yet again, if I took the phone outside and placed it on my car, the signal came back.

Now the mod I made, worked when I did the GPS test in the house - in fact it showed signal strength while in the garage without any windows.

I also messed up the taped antenna on the bottom of the phone. So what I did was just remove the tape, bought some adhesive foil, (looks like copper) and made a new antenna.

If you remove the back, (underneath the cover), you will see some copper type tabs that just touch the taped antenna - perhaps the contact is not very good so just put a piece of foil there to improve connectivity.

Now the taped antenna can be scraped with a sharp knife (carefully, don't cut it, just lightly scrape to remove the top layer and expose the copper), then you can apply a piece of foil to the exposed part - see picture.

So after doing all this, it seemed to work but then the next day it seemed to be back to square one - although before the tin foil "remedy", I did not have any reception.

Another thing I did - no picture, sorry - was I bought an antenna from eBay for a few bucks - regular wire antenna for the phones. I cut the wire and soldered it to the same place where the existing one is. This seemed to improve my reception of the phone but no effect on GPS. I just cut the other end of the wire and placed it inside the phone.

Now after all that - I seem to get good reception in some places and bad in others where my old phone would be good in all places.

As for the GPS - still not having good luck.

I did notice that the data download is only running 2G and I cannot change it - I tried the settings in the phone but it will not let me make the change even though I can see the option.

I don't know if the phone is capable of more than 2G or if the software on the phone is not allowing it.

At this point I am ready to just try and flash the firmware / rom and see what happens - I have no idea how to do that. The phone is rooted though.

I also would like to just get rid of the phone right now as I am tired of messing with it - so if anyone would like to purchase it, make an offer. I do have a brand new screen protector still in the plastic. Also have another type of screen protector which is much nicer and blue in color - I think that one can be reapplied to the phone - also in the plastic case.

So after my long (very long) message, can someone help me with trying to flash the phone and get 4G working?? Detailed steps would help.

Thanks to everyone for their help.
[Android Q&A, Help & Troubleshooting] kouger1:
As for flashing the phone goes - see attached screen shots of the phone.

I have tried to boot up the phone by holding down the power button, volume up key and the home key.

I have also tried with holding the volume down button.

I have attached the two screenshots when doing both.

Please advise how to flash the phone.

Details would help.

few days ago i did my own experiment .. i scrapped the black paint on the antenna to reveal the copper .. then i attached some aluminium tape .. did not noticed any change as there was no continuity b/w the adhesive and non adhesive sides of aluminium tape .. so i just folded one side a lttle and attached it just so i can make the conductive side attach the bare copper .. noticed improved signals .. but the aluminium has tape has quite a high electrical resistance ..

so what u did is also same ? i mean scraped the black paint to reveal coppper and attach the foil ?

was the foil conducting on both sides ? and b/w sides ..?

ur screen shot looks pretty awesome .. is it indoor or out door ?

i tried attaching a copper thin wires from to it but got no improvement ..

then i attached a wire from harddisk ide cable and immediatley got improved .. 4 bars inside room showed yellow .. earlier there were not even grey bars in the room ..

also how u scraped the black paint from antenna ? i used shaving blade .

EDIT

here is the flex antenna of the mt6575 galaxy s3 clone ..i took it out of my phone and used CTC cleaner to clean it for clear pic ... its just a strip with copper strip .. though there are tow terminals but both are shorted together ..

any antenna guy out there to educate us and help us improve it ?

i scraped the paint on it to reveal the copper surface and attached an aluminium foil onto it.
[Android Q&A, Help & Troubleshooting] kouger1:
I just used a stanley knife - very sharp - to scrape the black paint. As for the screen shot - it was indoors, in the garage.

I will try your harddisk method and see what happens.. I actually never tested to see if the adhesive foil is conducting on both sides but will do that today.

Do you have a picture of the wires you attached please?

Apart from all that, can you help with flashing the phone to another rom? I wan't to find out if my phone is capable of more than 2G, if not, then it is not worth keeping and I will get rid of it.

If you know anyone looking for one, I will let mine go very cheap.

Thanks again
[Android Q&A, Help & Troubleshooting] khankll:
i have only one camera phone now .. so cant post pics... but let me explain it ..

in ur post above . in the second pic the antenna u pointed out is for gps .. i removed it and lost all signals .. no signals what so ever attached it immediatly got few signals .. did this experiment to confirm it is for gps .. so finally i just used sharp shaving blade /razor and scraped the paint a little as in urs pic .. i first tried some petrol to remove the paint but was unsuccessful .. tried wd40 no luck .. tried CTC Cleaner no success howerver with ctc i was able to get the clear snap .... :good:

i then took an 80 conductor ide hard drive useless data cable .. and just removed one strip from it .. which will be like 2 inces ... or 3 inches .. that is very thin silver/aluminum wire .. and placed it on that scraped surface with aluminium adhesive tape .. i could get locked in my rom to 7 satellites .. earlier i wasnt even able to view any signal .. even in my balconony no i would hardly see few signals and it wont lock to any satellite though 12/13 would be visible .. now i can lock from inside my room ..

i tried with copper wire and immediately lost all signals ..
[Android Q&A, Help & Troubleshooting] kouger1:
Thanks for your advice. I tried an IDE cable but the cable is copper not silver/aluminum wire.

If I am understanding you correctly - just split the cable / ribbon cable so you are left with one strand. Then strip the plastic covering to expose the bare wire. Cut to length of about 2-3 inches and adhere to the exposed antenna that was scraped?

I don't get any signal at all. It shows 10 sats in view but no signal. I am going to have to try this in the morning again.

Please advise.

Also, if you have any idea on how to flash my rom - please let me know.

Thanks

Confirmed again this S3 clone MTK6575 is 3g capable device with frequency bands of 850 & 2100 MHz support

The 2 attached screenshots show both the 3g & 2g data connections from the stock rom

1 of the 2 sims speaks 850 MHz freq. band, so I get 3g (HSPDA) :)

While another sim speaks 900 MHz, then I get only 2g (EDGE) :(

[Android Q&A, Help & Troubleshooting] hhsgw:
I can't test if this phone support 4g? as 4g is not available in my place yet!

So check with ur service provider if they also run 3g which they should? and at what 3g frequency band?

As I said in my previous post: This S3 clone mt6575 supports 3g frequency bands of 850 & 2100 MHz.

Only sim with the above 3g freq bands will work in this handset, otherwise u will get only 2g.

If the sim speaks different freq band, then u need to use another 3g sim (850 or 2100) to test

So insert a proper sim (either slot will work), enable 3G service in Settings > Sim management,

then add New APN in Settings > More... > Mobile networks > Access Point Names >

(your sim network name) > phone menu (left side next to the middle home botton) > New APN

My Sim is from Simple Mobile - it works as 4G in my other phone (MyTouch) - when I insert it into my S3, on either sim slot, there is no option to select 3G as you mentioned.

"So insert a proper sim (either slot will work), enable 3G service in Settings > Sim management"

Any idea on what to do - do you think flashing the rom will fix this?

As I also mentioned in a previous post, when I try the MTK droid tools to flash I run into a problem - every time I start the "root" from the tool, it reboots the phone, tries to reconnect and then I get a popup saying "TouchWiz Home" has stopped working - the only option is to click OK and then the phone seems to reset again and again the popoup. Even if I pull the battery and boot up again, the popup comes back. I have to boot the phone with the volume, home and power button and force a reboot from that screen in order to get rid of the popup.

Andy ideas??

Thanks

Edit - one thing I forgot to mention - I am trying to do this without the sim inserted - will this make a difference?
[Android Q&A, Help & Troubleshooting] hhsgw:
Simple Mobile speaks 1700mhz !!

This S3 clone does not support the 1700mhz band, it will operate at 2G (EDGE) speeds on their network.

So u have to use another sim, may be AT&T which I learnt that they run 3g on 850/1900 bands

If u live in area where AT&T runs 850 band, u will then get 3g, otherwise only get 2g if live in 1900 network area.

You can insert 2 different sims in those two slots, set the simple mobile sim for voice call/sms/2g

while another e.g. AT&T sim for 3g data connection. I have been using this dual sim feature for months. :good:

Once u insert a proper freq. band of 3g sim, the device will detect it, and u will see the 3g menu

3G service menu is in Settings > tab the Sim management > scroll down to nearly the bottom of the page.

This is rather a hardware issue - the device radio only support 3g freq. bands of 850 & 2100 transmitting,

IMO, I don't think flashing a new rom can fix this? But u can try and tell me if I am wrong?

As to MTK droid tool problem, pls wail for KK, the owner of this thread, to give better solution, 'cause I'm a noob to this tool..:o
