Hi,
I've a big problem with my ZenFone GPS, it's very slow to fix and accuracy is very bad. It's totally unusable for car navigation. For example my moto G first gen 2013 have better accuracy (11 meters) and fix in 5s max versus 30/40s with bad accuracy (40meters).
I've try to upgrade to latest firmware, factory reset my phone but problem still here.
I google a little about my problem and I found i'm not alone to have this GPS issues.
Does someone found something to fix this problem ?

You're not the only one with this problem, bro. I also have a problem with GPS on my ZE500KL (by the way, i also had Moto G 2013 before and GPS works good on it)
AndroiTS GPS Test shows that GPS doesn't see any sattelites. The best result was connection with 2 sattelites, and the accuracy of GPS on Google Maps was very low in anyway.
I have tried factory reset, to downgrade to WW_12.8.5.118 Firmware & wipe cache partition, then tried also install WW_12.8.5.172 and WW_12.8.5.222 firmware and the result is the same - GPS not working.
The only thing I didn't tried yet is editing the "gps.conf" file, but I need root for this, and I don't want to lose the warranty
As I see on ASUS official forum, they know about the issue and they trying to resolve the problem (since november or something). :good:
Same for me
Gps position updates once a minute and accuracy is real ****. Had a road accident because of navigation problems
same problem for me...good phone, but GPS work badly
gps on my ze550kl keeps turning around and accuracy is very bad hope they will fix that in MM
I tried to post this message on the Asus Zentalk forum, but the site seems broken, it won't let me post anything.
I had a similar problem with my Moto G, I resolved this way (solution found in this forum, posted back to CM forum):
To make integrated GPS working you need to reboot in bootloader mode (hold volume down while turning on the phone), then attach the phone to the pc with the USB cable, and from the command prompt use fastboot to erase modemst1 and 2:
Code:
fastboot erase modemst1
fastboot erase modemst2
It will not erase anything tangible for the user (apparently).

I know that this is a different phone (I should get it soon btw, I hope I will not regret my choice) and that the commands probably won't work even with some modification, but it could give a hint to those trying to solve this problem.

Have you run the command prompt as Administrator?
Have you installed the latest or official ADB drivers?
Have you unlocked the bootloader? (I don't know if necessary, try the above first)
I also tried running as admin as well as downloaded the latest adb and drivers, same result
I have not yet unlocked my bootloader since there is no complete backup here at xda, and it is not possible to re lock the bootloader,
I will just be waiting if someone will try to it.

I'm investigating what happens in detail when these two partitions are erased.
I found two discussions that look interesting (specially the second):
http://forum.xda-developers.com/zenfone2/general/investigation-efs-t3153154
http://forum.xda-developers.com/showthread.php?t=2617276
In brief: these two partitions holds important information of the phone, like the IMEI. Erasing them cause the system to recreate them using the information backed-up in other partitions. But in some cases these backup partitions are empty and erasing the modemst partitions cause the phone radio to stop working (no more calls, 2G/3G/4G data and GPS) because the system cannot retrieve the serial numbers needed to make the radio work anywhere.
So it's better to do a manual backup of these partitions before erasing them (better a full backup with TWRP, that will backup all partitions including these).
Reading the second discussion linked above suggests me that the sudden bootloop problems that people are experiencing, are also connected to the corruption of these modemst partitions (corruption possibly caused by some firmware update or by some system app gone mad).
The fact that Asus after 2+ months still hasn't fixed the GPS problem, could mean IMO:
- that the problem isn't related to the above partitions and is more complicated than it seems (probable);
- that the problem is caused by the corruption of the partitions but it cannot be fixed with an OTA firmware update, but only manually with a technical intervention (full flash and/or terminal bashing) that regular users aren't capable of;
- that the problem can be fixed with a firmware update but Asus developers still haven't find that (improbable).
I should get the ZE500KL in a couple of days, then my theory could be tested directly and described in detail (if I get the same GPS problems after updates).
Thanks for your input regarding this, i would just use my bluetooth gps in order to navigate properly..

Yesterday I received the phone, I booted it to check if it works, then I immediately upgraded the firmware to the latest version, without OTA updates but downloading directly the latest full firmware from the Asus download site.
Then I booted the phone, played a little with it, did a full reset and re-flash the firmware.
Then I thought about GPS problems and I tested it with AndoiTS GPS Test and it seems to work fine, or at least I suppose this from the attached screenshot (I couldn't test it on the streets yet).
I don't have root permission or bootloader unlocked [yet], so you and everybody could try the same things I did:
- Factory data reset (from Settings > Backup and reset menu);
- wipe data/factory reset (boot into recovery by pressing Volume Down button while turning on the phone);
- full firmware flash (from recovery, you can copy the firmware zip file in a microSD or upload it via adb sideload).
Then after rebooting the phone complete the welcome procedure and repeat the three steps above another time.
I hope this will works for everybody.
Here is my screen shot using asus zenfone 2
Screenshot from asus zenfone 2 ze500kl
Merely 2 satellites
And here is the screenshot using xperia sp c5303,
I also updated using the zip in asus site and flashed it,
Btw, my asus has been rooted, but i see no difference after rooting it, same scenario 2 or less satellites, some times 5 but no fix

Another question what firmware version are you using, as far as my experience, the latest ww.12.8.5.222 firmware gives me this problem so i decided to do a full downgrade to the stock fw that comes with my phone, which is ww.12.8.5.118, for that fw works before

I used the latest firmware, the .222
The trick could be resetting and flashing, two times, but it's only an assumption.
BTW, into geolocation settings, I enabled the only GPS option when doing the test.
In your screenshot, it looks like AGPS is enabled, that is not GPS. Try setting only GPS in the geolocation settings and see what happens (maybe with screenshot).
Here it is without agps, i even left my phone in the open for about an hour, screen on, hoping it will fix even with one satellite, now even one satellite wont show up

Ok, it looks like the same exact problem as the Moto G, and the solution should be the same too.
But with the bootloader locked (and no way to unlock it at the moment), the only thing we can do is using the terminal with root privileges to backup and erase the partitions (with the dd command or something similar).
I'll study how to do this...
Just to update

so what did you do to solve it?
Hello, guys! It's now my 2nd post asking the exact same help. I'm very desperate to fix my phone : Asus Zenfone 5.
I have been looking for solutions for a long time, I'm not easily quit on googling. So far, this problem is one that haven't been fixed and very unlikely to be fixed
I have contacted many people including that Taiwan guy who is an expert on Zenfone 5 (forgot the name) and I'm EXTREMELY DESPERATE
I know this problem might be similiar with other case, but this one seems to be rare, because I have not found the solution.
Here is the timeline before my device got soft-bricked :
1. I upgraded to Lolipop with a different version of it's recovery, but still worked.
2. One day, ANR Keeps reporting that SystemUI has stopped. Rebooted and the phone went bootloop.
3. (probably the problem) I flashed wrong version of recovery (I think it was kitkat's recovery) and after then, I'm not able to get into DROIDBOOT.
I have tried several ways :
1. Sending package to my phone over ADB Sideload (It says something like error mounting blabla)
2. Flashing with xFSTK (It says something about driver, and I googled it. Found everyone with the same problem, endless solutions)
3. Downloaded about 1 gig of files (DEBRICK Files) and still, gets stuck somewhere.
So anyone have a solution for me, please?? I'm totally desperate right now, I lost hope. Never had this kind of problem, the thing is that so far, I never had such never-solved case in my life, I will always
find a solution from Google even that would take a long time. I have been searching passively for about 8 months, and I got none of those works
I will be very thankful if anyone would try to help this problem, I will bring detailed information you want, because I don't have solutions left.
Sorry for bad English
Thank You so much!
Christ, I was sure that I ticked it as a Q/A.
how to help? you are just telling about softbrick.
Hello everyone!
I have a big issue with this tablet: after the new update to 7.0 I notice the system is consuming a lot of internal space and the system is not stable like it should be.
What I would like to do is to revert to the previous firmware/version or try to install any other bootloader wich now is beeing very difficult because I dont know how to do and the steps that I read to do it are very complicated.
Does anyone can help me to install the firmware on this tablet?
I have everything, the tools, the firmwares, cables, the pc... everything.
Then other thing is when I try to go to bootloader, I mean, is in chinese!!! Is not even simple and looks I cant solv my problem at all.
Please, anyone can give me a hand?
Thanks in advance for all your help and sorry about my bad english.
I will give a party with those who can help me and I will offer beers to everyone!
Thanks!
Where did you get the firmware ?
I have exactly the same problems. I managed to get the Z300M software from the ASUS website but not the P00C. Would like to roll back to software from May or before.
same EXACT problem... looks like audio_dump .wav files are the culprit but cannot delete them. used fastboot to factory reset after 7.0 update and problem came back 3 days later! can't find any older updates for the p00c online either
Somebody posted a possible solution in another thread. Can you see if it works for you?
diplomatic said:
Hey guys, see if this works:
Install Engineer Mode MTK shortcut
Turn on developer options
Start Engineer Mode. Go to Hardware Testing -> Audio -> Audio Logger
Uncheck any boxes that are checked
Profit (and maybe reboot)
All in all, I don't understand why some tablets have the logging enabled and other don't, if this is indeed the issue. I've never seen it enabled, even after a factory reset.
If you have the audio logging issue on either the Z380M or the Z300M, please post:
Your firmware SKU
Your region code given by the property ro.config.versatility (may need a terminal app to read that via getprop)
The firmware version you were on when you reset your tablet

Hi Xda-developpers, nice to join the community !
1. What I did
I first intended to install ROM Custom Lineage OS on my HUawei P8 Lite (PRA-LX1)
Details : Android 7.0 / EMUI 5.0 / BUILD PRA-LX1C432B164
I managed to : unlock PHONE, FRP, Bootloader and Root it successfuly
I couldn't install Lineage because TWRP and recovery mode didn't work
2. What went wrong
It put a slightly different version of Android where...
...I cannot delete apps (but I still can install them). When I try to delete them, my phone restart and the apply still there
...I can't update to new versions
...I can't open "developper options" in Parameters (when I touch to open, it leaves parameters and go back home screen) and therefore I can't enable USB debug option and connect to the right Huawei software (Hisuite) which says even the cable is connected : the device isn't connected
3. What I tried to do to repair
3.1 Erecovery download latest version and erecovery : fail
3.2 remove SuperSu and unroot the phone : success
3.3 when I unrooted a possible upgrade appeared to a new version (the one I have now :
PRA-LX1C432B164
and the one proposed : PRA-LX1C432B212-FULL
Problem it was too good to be true, because I can't remove apps I am short of 1GB to install it (it download untill 100% but after says it needs 1GB)
I deleted eveything I can but still have :
Firmware : 6,55Go
Apply : 4,94Go
Pics, Videos, Audio, Cache, Others : 0Mo
4. What I am looking to do now
Restore everything normal as If I just bought the P8 Lite
How would you proceed ? :angel:
The SOLUTION that worked for me
Hi everyone I managed to get eveything back with my excellent and kind neighbour which is a app web developper
We installed an application that emulated a command line in the phone
We entered some lines found within this xda developpers forum
And it unlocked the USB debugging mode
We then searched and installed some ROM STOCK until we found the right one
It lounched a new version, I had to do a factory reset for everything to work properly
And thats it, brand new !
I canno't give you more details because we spent hours to do it and they were too many variable
But I wanted to tell here how we did it
Hello everyone,
I've flashed my phones for quite a few years, messed things up from time to time, but always found solutions. This time however, i don't really know where to start.
I kept my Zenfone Max Pro M1 in its original state for the time of warranty and only unlocked and flashed it a few months ago. I first got into problems with the storage (couldn't install apps) and in my attempt to fix it i kinda bricked my phone... i don't remember all the steps i took, but what ended up working was Qualcomm Flash Image Loader (QFIL) with an Image i found online.
After that i flashed Spark OS and later Superior OS (both clean flashes), but with both i'm having problems with the internet connection. I only get EDGE which is really slow (WiFi, phone calls and everything else works fine). Tried out all possibly APNs and swapped SIM-cards with a friend to rule that out.
I'm suspecting some file needed for UMTS and up (specifically for european networks?) has been overwritten, but i haven't been able to find anything (great job by Microsoft renaming their browser also to Edge, doesn't make the search easier).
I recall having similar problems back then and flashing a certain radio.img fixed it, but i don't find anything about that either. Maybe something else baseband related? Do you think Asus could help me out? What to ask for?
Grateful for any input
Update: realized my serialnumber is displayed as C4ATAS000000 which is not that uncommon and might be the culprit. haven't found a working solution yet, but working on it
