Detected and undtected

I am getting the same problem. I have Win7 64b and it detects the device and after couple of seconds the device gets removed.

It appears it loads "MediaTek PreLoader USB VCOM Port (COM3)" and after couple of seconds device gets disconnected. Only sanlaa encountered this problem. Did anybody else encountered this?

-----------------------------------

Please ignore above noob issue. That was what is required. USB driver is loaded by flash tool when you remove and put the battery again after pressing F9(Download button). Thus the flash tool detects the preloader and loads the usb driver, so above is not issue but a sign that driver is installed correctly :)

I am running A750_S148_120428_cybermaus_V0.1 and I downloaded and installed: Boat Browser, Boat Browser Mini, Qype, Whatsapp. at the forst attempt it showed "Error: No connection" but the second attempt was succesfull.

Hope it helps, or might increase even more the mistery :)

Card is in roaming: I tried in my Lenovo A750 my brothers 3-UK SIM card (three.co.uk), and it showed me the same thing, then I read about it and it looks like 3-UK is roaming inside UK with the network T-Mobile because 3-UK doesn't have enough antennas, I presume when the SIMcard wanted to connect to T-Mobile the phone was giving me the warning that it is roaming.

If you are in a similar situation that might explain why it said it is roaming.

In etov2 it was all fine.

Only ICS makes problems....

I have tested the changes in the build.prop, but no effect.

I have changed manufacurer, brand, and model.

Now i will try the density change.

I think the density norm is 240.

The phone has this density.

I had problems with my Lenovo A750 to install runkeeper app. I found out, that the network location apk and some google maps files are missing (even with Google maps installed). So I did the following (on a rooted phone):

1. Searched for the CM gapps zip (mine is 2.3.6, so I downloaded the CM7 gapps, hopefully the same works for 4.0.3 with the CM9 gapps).

2. Found the following 3 files: com.google.android.maps.jar, com.google.android.maps.xml, NetworkLocation.apk

3. I uploaded the 3 files to the sdcard.

4. With the ES File explorer I moved the files to the following directories:

/system/framework/com.google.android.maps.jar；

/system/etc/permission/com.google.android.maps.xml；

/system/app/NetworkLocation.apk

5. Set permission to: rw- r-- r-- (I don't know if it is necessary or not, but I did it that way)

6. Reboot

After that my runkeeper app worked!

Maybe that helps for someone having the same problem.
[Miscellaneous Android Development] johhnyhotrocks:
Thanks for that, I am on T mobile so maybe that explains it. But his last phone an HTC Wildfire S didnt show that message.
[Miscellaneous Android Development] Timer2000:
Thx,

but this files are all there.

Cybermaus has put this in his rom...i think.

Eto provide a stable ics rom version i there blog,

i think it is the s306, which we allways have

New Question:

how long is your battery life.

i use the battery monitor widget.

it shows the mA.

my phone shows between 2mA and 50mA at sleep.

is this normaly?

i think it is to much.

i have phones they show 2mA at sleep.
[Miscellaneous Android Development] paulfc:
need A750_S305_120514_cybermaus_ICS_V0.rar file. The file you requested has limited access: Publisher only. . Thanks
[Miscellaneous Android Development] cybermaus:
@paulfc

I changed it to allow download.

I figured with V1's in existence, people would not need V0's anymore.

I still think that is true for GB, but it seems for ICS you may need V0 before going to V1. V0.1 is not needed.

@Timer2000

I got the author of Turbo GPS 2 to specifically change the apps manifest 'coarse/network.location' requirement from required to optional, and it did result in being listed as compatible (where before it was not-compatible). So I am quite sure it is the network.location that is causing this, not dpi.

If you can get your Clever-Tanken to make the same change. Turbo GPS made the change in 5 minutes (and then I had to wait 1 hour for play store to show the new version)
[Miscellaneous Android Development] cybermaus:
Yes, all those files in in both V1 ROM's.

The problem is not that location is not working. It is working. The problem is that the phone does not list location services as a capability, so apps are not listed.

Do you have a link to that Eto ICS S306 ROM?

At this moment, I only have links to Eto's S143.
[Miscellaneous Android Development] Timer2000:
Sorry,

i`m waiting for the Firmware.

I hope eto will send them.

But, what is with the location and Turbo GPS 2.

Have you a new location file and it works with the store?

Can you send the file?
[Miscellaneous Android Development] cybermaus:
No, the application author changed his app for us.

Let me explain one last time what I think is happening:

It looks like Lenovo did not feel it was needed to report to Google that A750 ICS could do network.location. The reason is likely because the Chinese market does not (allow to) use google. They want to use their own (probably with added citizen tracking) Which is also why google's location apk is not normally installed into the phone.

Therefore, the Google servers thinks the "Lenovo A750" phone cannot do location, and do not allow location-requiring apps to be downloaded. This is Google server based. I suspect there is nothing we can do about that, other than to make the phone report itself as a completely other phone.

As a test for me, the Turbo GPS maker changed his app so that network.location was no longer a required capability, and he uploaded that change to the Google store. And indeed, suddenly I could find and download it. You need to ask the same from Clever Tanken.

Mind however, I am in a Cairo, where neither cell nor wifi location works, so while i can now (since the change) download and install Turbo GPS, but I cannot actually see if it works (other than with GPS)
[Miscellaneous Android Development] Timer2000:
Ok,

but i have changed the model and brand in the build.prop, that the play store means that is a samsung nexus s.

But nothing.....

And.

I have said that the network location dosn`t work.

And the store has the same opinion.

Now, the both problems are one problem....

if we finde the solotion it will all work.....?
[Miscellaneous Android Development] oz42:
I just tried Mobile Uncles engineering tests (Cybermaus S306).

Start it, choose Engineer Mode (MTK)

Tap location

It will tell "Google network location binding failed" and "Google geocoder binding failed". I swiched both to Mediatek, it did not help, the error messages were the same. A firewall thing perhaps? We are niot behind the "Great Chinese Firewall". ;-)

I guess that is the problem.

Just extract both S148 files (empty.userdata.rar and empty.fat_A750.rar) where they are and delete the RAR files. Then flash S148. Afterwards, install S305, put S306 onto the SD card and flash that from recovery. After booting S306, I would format the internal SD card and do a factory reset from "settings" -> "backup & reset".

Lenovo a750 english manual

Hello to Everyone,

One week ago I have bought a Lenovo A750. Fairly new user in the Android world, I have started to read everything about OS and Lenovo phone. [I felt lucky finding this thread.]

Simple, stupid question: since I have only the hardware, charger, headset and a Chinese user manual, could anybody please share the English user manual of Lenovo A750? :)

Many thanks in advance.
[Miscellaneous Android Development] cybermaus:
YES! thanks you for still keeping an eye on this thread and helping out when we get stuck.

Despite my suspicions, I spend most free time yesterday tryign to find how to set 'capabilities' on the phone, this seems like it.

Unfortunately, I am still in a place with location does not work, period, and whats more, I messed up the phone in my attempts, maps does not even start anymore (exactly why I should not play while on a business trip). But it does look very promising

EDIT: I make a update.zip that update your ICS A750 by updating the info Bruno refers to. Load ICS V1.1 (update.zip type) from my Dev-Host, use Titanium or recovery to clear cache for Play Store, and from now on location apps are shown as compatible.

To repeat: This does not fix location services if it is broken. It only ensures location applications are no longer listed as incompatible. Also, some apps need even more capabilities like NFC etc, so they would still be incompatible. If you have such an app, please get hold of (somehow) the official apk, and send it, then I can find out what its exact needed features are.

Thanks Bruno!
[Miscellaneous Android Development] oz42:
There is no English manual as it is a Chinese phone. But I thing any Android 4 manual will help.
[Miscellaneous Android Development] Timer2000:
Cool.

I love you ;)

Ok, the location service ist still broken, but the apps are listed to install.

I think you will make the rest,too.

It is possible ,that the permissions not correct in the fix?

I have it manually changed tk rw- r-- r--.

And than the app can be installed...
[Miscellaneous Android Development] bgcngm:
What is exactly the problem that you are having with location services?
[Miscellaneous Android Development] Timer2000:
It dos not work.

Only Google Maps can use the network location.

All the rest of apps have no access to this service.

GPS works fine....
[Miscellaneous Android Development] bgcngm:
I have previously shared here a fix for location services. Google Maps was not working for me, but it is solved now.

Can you let me know which app you're using so that I can give it a try?
[Miscellaneous Android Development] guesswhoesis:
another problem I have is: many apps in the store cannot be found? why?
[Miscellaneous Android Development] Timer2000:

But with no effect.

It is possible that i have made a mistake with your tipp.

Your new tipp with the permissions dos not work for me.

But the changes by cybermaus work.

I think cybermaus must try your tip...

The apps, if dos not work are:

klicktel, adac wandern, adac radfahren, clever-tanken, qype, aloqa, news & weather, cash group automaten usw....
[Miscellaneous Android Development] bgcngm:
For sure! Location services works for me with the patch that I have shared before, not only for Google Maps. ;)
[Miscellaneous Android Development] Timer2000:
Ok,

what is the mistake?

In your zip are three folders.

all the *.xml i have put to \system\etc\permissions.

Need I the 3config folder?

I have put the files again.

I have changed the permissions of the files to rw- r-- r--

and reboot the phone...

at reboot i have a message on the display:

"andorid is upgrading the apps"

But no results...

Ok,

I have tested all my apps.

The most apps run with the mtk-setting (binding).

But not all my apps.

I don`t know,

but after setting back to google binding.

It works, too.

Now, it work with all my apps.

It is perfect for me.

I hope cybermaus fix it in ther firmware.

googlefix.rar must be integrated and the settings checked.

Has anybody find the Release of S306?
[Miscellaneous Android Development] cybermaus:
@Timer2000

I admit that I was on the wrong track. I added some of Bruno's stuff (after ensuring it fits with the A750 config files) into ICS V1.2 update.zip. Just apply V1.2 onto V1 (you can skip V1.1) and it should work for all western apps that expect google location services rather than mediatek location services.

I was mislead by the fact that for me, both location apps that I used *did* work with the Chinese location provider. And later as the discussion raged, I could not check anything, because nothing worked in my Cairo hotel (wifi not recorded by google, cell location nor working on roaming sim, and no data on local sim) Oh, and I had to spend some time for my employer too, rather than hobbying :D

Anyway, I tested the V1.2 on my own phone, using 2 extra location apps that failed before, and now they are fast and precise.

Edit: PS, to people applying this: after applying you may need to clear data for the location apps in question and for market

[Miscellaneous Android Development] cybermaus:
That is not the official S306 release !!

That is with the modified boot.img, to root the S306, but it roots it using a method that personally I do not like.

Search back a few pages in this thread, and you will find someone did intercept the original OTA and provided it. I added it to the first page already a week ago for easy find!

However, be warned that the original S306 OTA can only be applied if you already have S305, and also, it will overwrite any recovery you may have installed. You may as well use my V1, which is really nothing more than original S306 without Chinese, without the recovery, and with Google apps.

And then apply V1.2 of course to fix location even further.

When I installed v1.1, it didn't work immediately. I cleared Playstore cache, then dalvik cache. Still when when I checked Playstore, the incompatibility message was still there. Suddenly when I was at one of the incompatible app page, the message disappeared. I then checked other imcompatible apps, they were all no more incompatible too. May want to try clearing the caches like I did.
[Miscellaneous Android Development] cybermaus:
@guesswhoesis

Yes, but that is because of other reasons, nothing to do with location. It is also why there is a working whatsapp the etotalk folder of my Dev-Host. download and install that.

BTW: Rather than merely mentioning 'cannot find some apps', name the specific app, and also send me the original app's apk (so not any modded one), if you can find it somewhere, like on your other phone. I can then find out what features the app needs, and why the A750 does not list that features.

Some apps need things that the A750 really does not have, like 'compass' or 'nfc', and we would need to 'falsify' the phone's features.

Also, just to repeat: V1.1 is included in V1.2, it fixes both the market for location, and the location services itself. It does *not* fix the market for other causes of incompatibility, because we first need to know the exact cause.
[Miscellaneous Android Development] cybermaus:
@oz42; regarding the 'dead after charge while off'

Ok, I had some opportunity to flash several combinations myself, and this is the one that I found works well.

PRELOADER : From GB (like from my GB V1 or original S148)
DSP_BL : Does not matter, ICS and GB are identical
MBR : From ICS (like from my ICS V0 or original S305)
EBR1 : Does not matter, ICS and GB are identical
UBOOT : From GB (like from my GB V1 or original S148)
BOOTIMG : Leave unflashed, needs to be from whatever ROM you are on
RECOVERY : Use CWMR Touch, any of my flash packages
SEC_RO : Leave unflashed, needs to be from whatever ROM you are on
LOGO : Whichever you want
EBR2 : Does not matter, ICS and GB are identical
<rest> : Leave unflashed, needs to be from whatever ROM you are on

To put it in another way, use all from ICS, except PRELOADER and UBOOT. If you have a working S306, just flash only these two from GB

It solves the 'dead after charge' problem, and it makes the boot-sequence for Recovery easy again (not so time critical on when to push the volume buttons) and it does allow again the Factory mode (camera button during boot) which I had lost with the ICS.

And with normal boot, it just starts ICS as normal (for me at least). I did not need to clear cache or anything.

About the location thing: is it okay that location only works with Wifi or 3G data connection enabled? When I disable both, Google Places does not find my location. Or does that work only in non-rural areas? "My" transmitter mast is about 5 km away.

Jpegs

Anyone know a solution for getting the phone to recognise jpegs on the sd card?
[Miscellaneous Android Development] oz42:
No problem here with Jpeg files.
[Miscellaneous Android Development] cybermaus:
Indeed, if you disable data, wifi and gps it may be somewhat difficult to determine your location. Is that what you meant to ask? :confused:
[Miscellaneous Android Development] oz42:
That is exactly what I meant. I assumed that location.services could determine my position with GSM only somehow.
[Miscellaneous Android Development] cybermaus:
I am sure the CIA, MI6, 911 and 112 can see roughly where you are based on GSM alone, but that information needs to travel back to the phone, and alas, they chose to require data for that.
[Miscellaneous Android Development] oz42:
Hmm... on http://developer.android.com/guide/topics/location/obtaining-user-location.html they say that the cell ID can provide location information... but ok, as long as there is no database of all radio masts on the phone, it will need a data connection.
[Miscellaneous Android Development] cybermaus:
iGO will work if you copy the iGO directory from the external to the internal sd card.

Or alternatively if you after every boot perform command "mkdir /mnt/sdcard/sdcard2; mount -o bind /mnt/sdcard2 /mnt/sdcard/sdcard2"

Once I find a method of doing that automatically after every boot, it will become V1.3, because I use iGO myself too
[Miscellaneous Android Development] oz42:
That would be nice, Sygic has the same problem.
