i have a problem with navigation gps on my huawei rio-l01, the gps antenna doesnt work, it lose signal continously or it is very inaccurate.
i try to reset to factory options in recovery, or different option as: only gps, gps and mobile connection
i think it is an harware problem but I cannot find the spare part on internet

HI guys, wherre can i down load TOM TOM for X1?
is it "turn by turn" navigation? is that what A-GPS means?
Assisted GPS, generally abbreviated as A-GPS, is a system which can improve the startup performance of a GPS satellite-based positioning system. It is used extensively with GPS-capable cellular phones as its development was accelerated by the U.S. FCC's 911 mandate making the location of a cell phone available to emergency call dispatchers.[1]
[edit]
Description
GPS operation uses radio signals from satellites. In very poor signal conditions, for example in a city, these signals may suffer multipath where signals bounce confusingly off buildings, or be weakened by passing through walls or tree cover. When first turned on in these conditions, some non-assisted GPS navigation devices may not be able to work out a position due to the fragmentary signal, rendering them unable to function until a clear signal can be received continuously for up to 40 seconds (the time needed to download the GPS ephemeris).
An Assisted GPS system can address these problems by using data available from a network.
Assistance falls into two categories:
Using information known to the assistance server but not the GPS receiver
It can supply orbital data or almanac for the GPS satellites to the GPS receiver, enabling the GPS receiver to lock to the satellites more rapidly in some cases.
The network can provide precise time.
The device captures a snapshot of the GPS signal, with approximate time, for the server to later process into a position.
Accurate, surveyed coordinates for the cell site towers allow better knowledge of local ionospheric conditions and other conditions affecting the GPS signal than the GPS receiver alone, enabling more precise calculation of position. (See also Wide Area Augmentation System and CellHunter.)
Calculation of position by the server using information from the GPS receiver
The assistance server has a good satellite signal, and plentiful computation power, so it can compare fragmentary signals relayed to it by GPS receivers, with the satellite signal it receives directly, and then inform the GPS receiver or emergency services of the GPS receiver's position.
As an additional benefit, in some A-GPS device implementations, the amount of CPU and programming required for a GPS receiver is reduced by offloading most of the work onto the assistance server. For modern hardware this is not a major consideration but many 20th century GPS navigation devices used Intel 80386-class 16 MHz CPUs[citation needed] or similar hardware.
A typical A-GPS-enabled receiver will use a data connection (Internet or other) to contact the assistance server for A-GPS information. Some A-GPS devices cannot fall back to standard GPS, needing cell tower or internet signal as these A-GPS devices won't function with only GPS satellite signal.
Many mobile phones combine A-GPS and other location services including Wi-Fi Positioning System and cell-site triangulation in a hybrid positioning system.[2]
High Sensitivity GPS is an allied technology that addresses some of these issues in a way that does not require additional infrastructure. However, unlike some forms of A-GPS, high-sensitivity GPS cannot provide a fix instantaneously when the GPS receiver has been off for some time.

You will have to do a lot of reading though..

Above rom is nice, but the GPS does not connect very often. I tried re-flash, re-starts but the problem remains. Strange is that sometimes it connects in 10 seconds, but I can not rely on it.
Who can help me with this.
GPS not connect for everytime in my device. Only searching GPS signal. They found my location only with wifi, not GPS
Hello,
I've new LS970(Sprint) flashed to E975 rom. And I have GPS problem: I can't see any sattelites and NMEA stream, tried several programs. I had same problem with LS970 rom. Should NMEA be active during no GPS signal? Maybe it could be possible to access serial tty where GPS is connected to send it some debug commands? What device in /dev/ is GPS? I don't know if you understand my me
Some time it gets location with accuracy of 20m, but only when connected to wifi internet, but still no sattelites in list.
I am in Europe.
Thank you,

the real Solution:good:
i flashed N7100XXUEMK9_N7100BTUEMK2_BTU.zip (stock 4.3 rom) along with pit file for n7100 16gb version .....and both wifi and bluetooth worked 100%
inbox me if you need the links to the files because i cant post external links as yet am a noob:laugh:
no need to do all this stuff.
just apply dr ketan wifi fix.
u can get it on xda just search it
wifi patch

@ rohan164, isn't the wifi patch only for the older bootloaders such as mj5....
or if not please post a list of compatible bootloaders.....
I sometimes have a problem with my 5T where the wifi radio will stop working soon after enabling bluetooth. My wifi network is on 2.4ghz and bluetooth (and USB3) can interfere with it, and I think that is what is happening here.
When this happens I will no longer be able to associate with my wifi network until I reboot the device.
Is there a way to fully reset the wifi or bluetooth radios from a shell? I could write a little script to run when my wifi radio breaks to fix it, rather than reboot.
Simply disabling wifi and bluetooth from the pulldown menu doesn't work. I don't know if it's possible to reset the driver or hardware somehow without a full reboot, but that would be nice.
