[Upgrading, Modifying and Unlocking] zopozp998:
Hi to all!

Well, I can give you a few guidelines about solving the GPS. Use GPS fix guide in PDF from user Dmitry.Stepanenko (BIG THANKS DMITRY!!!) - it will solve all the reception and all issues regarding the GPS signal, the exact location, the navigation (in the offline gps navigation apps, you wont need 3g/4g nor wifi) - and all that with the OLD antenna (my device was produced in January/14). You will have a GPS fix in 3 seconds!!!!

So the real reason for the problems with the GPS is this contact as also Dmitry describes in his guide - the contact between the connectors and the antenna. Zopo was aware of that.

The other thing what I think is really bad is that Zopo as manufacturer of this model (FLAGSHIP MODEL in that time) did not move a finger to resolve the issue(s). They just went on and released the next model - the ZP999

which is now in pre-sale. Everybody who is thinking about buying this model (zp999) should look in to the problematic of the ZP998 to eventually avoid being dissapointed in the future.

This is not the way to go - all purchasers of the ZP998 should get a compensation in cash/refund for all this hasle with the audio, gps and so on - issues which were not "officialy" fixed by the manufacturer.

I can tell that Dmitri's guid helped me a lot to get fix faster but frenkly, in real usage it did not worked with sygic i.e. navigating arrow is still jumping on the map...
[Upgrading, Modifying and Unlocking] zopozp998:
Sygic, Copilot, Navfree, Be-on-road - all this offline gps apps work without problems after the "dimitry" fix. Before the fix they were all jumping over the maps like a beheded fly...

Try to download the "MTK Suite" app and use it to refresh the EPO files... After the refresh reboot the device and give turn on the Gps and test.
[Upgrading, Modifying and Unlocking] dibon321:
Now I have installed new antenna and ir doesn't work at all! Sh**y poor zopo :-/ I'll try your advise as the last chance.
[Upgrading, Modifying and Unlocking] spout17:
True,

Same experience here, second driving test was even worse. Connection drops and when the fix is done the accuracy is horrible - jumping on the map as hell.

Dibon, do you have also Dmitri's fix applied together with the new antena? That option is the last resort for me...
[Upgrading, Modifying and Unlocking] dibon321:
Yes, after dissatisfaction with new antena, I have applied Dmitris fix method. This helped me with old antenna to get better fix but at the end, navigating was not able at all (jumping on the map, etc.). With new antenna I can't get even fix, sometime one sattelite, no more and it loosing fix every few seconds. I don't know if I made something wrong, but I don't think so.

Edit:

I tried again delet mtkgps.dat and epo.dat, restart phone and download EPO.dat. Nothing new happend, so phone is now placed on the window from the outside because is too cold to leave there even dog. :D
[Upgrading, Modifying and Unlocking] dibon321:
There is let's say improvement, but not so big deal and as spout17 said, on-road test was terrible anyway. I will make on-road test too.

Edit:

I have tested Sygic 14.6.8 and even only few km test, it looked very good and useful. Also Waze is kind useful. :) Only once waze didn't know where I am, when I changed direction abot 180°. See pictures.
[Upgrading, Modifying and Unlocking] spout17:
Dimitri's GPS + new antenna is working

Hi guys,

It seems that the last resort - Dimitri's fix in combination with the new antenna is working.

Fix was completed in a few secs and 9-10 sattelites working with the accuracy about 5m.

Driving test was also good - no signal drops, no jumping across the map.

So Dimitri's fix is the one and only GPS fix solution. New antena is just increasing the signal a bit.
[Upgrading, Modifying and Unlocking] LupusWorax:
Received and installed the replacement antenna today. For better connection I added some sort of spacer made out of tesa to the back of the contact area of the new gps antenna.

Signal improved significant on my device.

In the middle of my office:

and near the windows:

Am I the only one who received 2 free screen protectors with the antenna??
[Upgrading, Modifying and Unlocking] tempelakos:
If you had bought the zp998 from zopomobileshop, they send with new antenna, two screen protector for free.
[Upgrading, Modifying and Unlocking] dibon321:
I have received two antennas and two screen protectors :)
[Upgrading, Modifying and Unlocking] spout17:
I think they know that the new antenna sucks, so they send two proterctors to anyone at least ?
[Upgrading, Modifying and Unlocking] LupusWorax:
and while driving:

Most important part on replacing the antenna is to make sure the spring loaded pins on the mainboard make good contact to the gold plated contact area of the antenna. ( again, thats why I used some folded tesa on the back of the antenna contact area)
[Upgrading, Modifying and Unlocking] dibon321:
That's nice [emoji4] [emoji3] I have used double sided tape according to Dmitri's guide, but I don't have that great result in gps test as you [emoji32] which ROM do you use?

[Upgrading, Modifying and Unlocking] API182:
Hi guys, this seems to be the only active place to speak about the ZP998 so here goes...

Basically, long story short, I've had 2 of the ZP998s brand new since July (not mine, 1 is my Sisters and 1 belongs to a friend, but I orginally purchased them...), they've been working fine up until recently, basically, the camera quality has gone absolute sh1t! Both Cameras (front and rear) present lines on dark colours... When a picture is taken, you can zoom into a black area and you can see evenly spaced horizontal lines in dark green across the whole image... I initially thought this was hardware to blame when my friend first came to me wish this issue but once I asked my Sister if I could have a look at hers I now think its software as there was a software update via OTA not too long back and I'm thinking for both to have gone the same way in the same timeframe then it would be a bit of a coinsodence if it were hardware failure wouldn't it..?

Is anyone else experiencing this issue?

Thanks, Adam.

Now thank you., Grancapitan.

- You have amended my gps antenna fix manual (why?),

- You have advised people to bend antenna contacts

I WARNED PEOPLE NOT TO DO IT in my manual, and made it RED
[Upgrading, Modifying and Unlocking] Grancapitan:
Hello: Sorry my bad English.

Unmodified any manual.

I have found several contributions collected separately.

I have cast all my personal experience and have made a suitable gps.conf for phone, with interesting results (my tutorial:http://www.htcmania.com/showthread.php?t=902640).

Now with my last gps.conf (insert the file), and works with the new, supplied antenna zopomobile (http://www.zopomobileshop.com/en/307-enhanced-gps-internal-antenna-for-zp998.html), the results do not envy any mobile with Mediatek processor. The gps.conf is valid for the world.

I do not seek controversy or fame, just to help people.

A greeting.

Serious charging problem

Recently I replaced my damaged USB port by replacing all that little board on the bottom of phone. I've noticed that phone is charging a bit slower since the port was broken, however changing board to the new one made this problem escalate.

While USB port was broken I have to tense the charging cable to the bottom very hard, so sometimes a little flickering between "charging" and "not charging" occured. However, after replacing that board situation is terrible!!! It charges just 2% in 30 minutes!!! It charged from 10% just to 80% in 6 hours!!!

I can't read any values in Battery Current application, Engineer Mode shows me about 4300mV battery voltage. Is it battery fault or maybe something more?

Please help me!

could you guys help me out for flashing?
[Upgrading, Modifying and Unlocking] Pipes59:
I had a similar problem installing the Vcom drivers. It seems these drivers are not digitally signed and win8 won't play with them.

You need to put win8 into a more relaxed mode about this.

I cannot post links here as yet so you will need to google "installing unsigned drivers in windows 8" You basically need to restart your PC in a special mode which is done via the start up options.

Good Luck, Pipes

For 7 try this:

Disable signature verification of drivers:

Go to Start Menu > Run and type the following command:

bcdedit /set nointegritychecks ON

Restart the PC and install the unsigned driver

Note that it is highly recommended to enable the signature verification of drivers

Go to Start Menu > Run and type the following command:

bcdedit /set nointegritychecks OFF

Restart your PC

Instead of saying stupid things , I tell you something good .

My account here is from 2012 or before, but I have less than 10 posts and I can not post external links .

In fact, I posted the link on Androidiani.com specific .

I send you in private the link in the hope that you can share it on this thread.

---------- Post added at 10:28 AM ---------- Previous post was at 10:20 AM ----------

However however I am studying a bit like compiling a kernel ... what is missing is the defconfig for our zopo 998 .

There are two roads :

1 ) find this blessed defconfig file ;

2 ) create a generic file defconfig and troubleshoot hand hand .

From what I understand we have as hardware configuration for this kernel the " vanzo92_cwet_kk " .

It is contained in the sources that I have sent to the friend who first quoted me .

My knowledge on the kernel stops to fill a simple file defconfig already own .

If you can participate actively .

The first aim would be to create a stable kernel for Android 4.4.2 ( maybe 4.4.4 ) .

Then maybe Lollipop .

Everything is in our participation .

MAKE AHEAD PEOPLE !!! :)

In looking at your picture. The upper connector does not looked locked. Hard to tell from here.. Those flat type cables have a pressure type lock that needs to engaged to work.

Maybe you can check out some videos on this connector type. Can be confusing as to where the cable gets inserted.

I finally bought LG G4. ZOPO can go **** themselfs. I've never experienced worse customer and product service. This phone had some potential to be a good and useful device. Instead I lost countless hours attempting make simple features like GPS and audio playback work. Its not worth the hassle and ZOPO do not deserve your money for this piece of crap. I will never ever buy another chinese phone from any company because of the negative experience with this phone.

Do not buy ZOPO products. Companies like this do not deserve support. because they just take your money and leave you alone to deal with their unfinished products.

Well, it is true, no support at all and I think it will gonna die with android 4.4

Just if someone could manage to make an optimized rom, because this phone spec have a great potential.

I see that almoust everyone shut down their emotion with this phone, and on this thread is very quiet. Sad.
[Upgrading, Modifying and Unlocking] Pipes59:
I also agree, phone has good hardware but the software quirks are not addressed by Zopo.

Reversed gyro direction for SBS applications and bad GPS are the downfalls for me. And since the hardware seems fine why did they not offer an updates for these bugs?..... Instead just say buy my new model and it's fine. Bunch of BS, if you ask me. NEVER AGAIN!!!

Hi all,

I hear a lot of hate about zp998. I just got it second hand for almost no money, because the screen is higher res. than my Sony. I bought it for playing a VR video during an art installation, however, well... we all know that gyro is inverted on this device... and I had to find out a little bit too late. Is there a fix for this? Maybe a video player that enabled gyro inverse or a new ROM?

Thanks!

p.s.

I do apologies for lifting this old topic up...and maybe someone mentioned the solution on the previous pages, i just couldn't find it...
[Upgrading, Modifying and Unlocking] Pipes59:
I had tried all avenues to get around the gyro issue. I had no luck and gave up. Same with hoping for a good GPS fix.

I'm afraid you are a good example of you get what you pay for. Too bad I got burnt paying full price. Willing to sell for next to nothing myself. Now have a Samsung Note 4 and no comparison. Everything just works correctly.
[Upgrading, Modifying and Unlocking] charrette:
I see, shame... Would have thought that VR video playback wouldn't be that much of an issue. Zopo used to be alright...

I am currently playing with different apps, I have a fairly good relationship with a couple of developers, maybe they can add inverted gyro to their app...

Thanks anyhow.
