Hello.

I have been hearing things about this zopo smartphone not being very trusty about its gps and microfone. Is that true?

What about the new 998 model? Did anyone notice any bugs on it? Would the 998 be a better purchase rather the 990? Any info about when will it be available for purchase (998). I was thinking of buying a zopo mobile from the official online shop. Would that be a good idea or should i refer to another retailer? I'm from Greece/Europe.

Thanks in advance and good to be here :)

No problem with microphone... No fix exist because it's a hardware issue

Envoyé de mon ZP990 en utilisant Tapatalk
[Upgrading, Modifying and Unlocking] HorstDCC:
With tweaking you can get the microphone to 80% of what it should be. A few years ago this type of quality was common. It's not that bad.

The same goes for the speakers.

The included earplugs are rubbish, because of thàt microphone.

The GPS actually works fine once you have a fix. I use it as a pedestrian as well as while driving my car.

The tweaking is mainly about getting a fix faster.

Comments in this thread about precision are based on truth. I used to have GPSses that gave me a position with 1.5m precision. The ZP990 seems to have a precision of about 4m, which is acceptable to me.

When you don't have a satellite fix and you need to rely on the assisted bit then the ZP990 is as imprecise as any other device.

As for the next model, it is wise to wait and see. The proverb that "Newer isn't always better." has gotten a whole new meaning with Chinese export products.

By tweaking you mean updating the firmware thats is posted in the #2 message by Ghost? Does it envolve rooting? And we are talking about the phones microfone thats has poor reception not the earplugs microphone.

How good are the earplugs for listening to music?

The Gps is not essential for me, but good to know that is fixable.

I get that we get a little too judgmental with these "made in China" products

Hi,

By tweaking I main using engineering mode to set levels and stuff. I'm not suing Ghosts ROM because I haven't felt the need for it and he didn't document any advantage that it might hold from a settings or tweaking point of view.

My ZP990 is rooted in order to do some modifications.

Microphones: the build in one is not brilliant, the earplug one is simply bad.

Earplugs for listening to music are almost a matter of taste. These don't distort but they are not of sufficient quality to give me all frequencies I can detect. They sound flat. They are adequate for the sound quality of the build in FM radio. They are not even close to my Beats earplugs and I would call those moderately good, not excellent.

:)

I do my best not to be judgmental in general, but yeah, sometimes I am/we are.

And even though I can state what's not so good about my ZOPO I'm still happy with it.

@billouetaudrey

I wonder whether all batches of the ZP990 are equal.

Happy new year as well. To all actually.

Tweaking system file and settings is fairly easy.

The difficult part is finding out what to do and for that there is only one approach: read and read more. XDA is a rich source for all this information but since Mediatek chipbased phones are less popular with cooks there aren't any dedicated sub-fora here.

The real reason for that unpopularity is the lack of documentation and openess on the hardware/drivers/frameworks. For illustrative anecdotes google "CyanogenMod mediatek".

So tweaking is mostly limited to adapting settings in configuration.

It is not riskfree if you start messing with anything that involves electricity and temperature. For instance, I wouldn't try and overclock or undervolt the ZP990. But adapting levels for a microphone can not be harmfull to your hardware.

Make nandroid backups frequently!

Instead of looking for info on this model of ZOPO you can look for that type of information for the chipset that the ZP990 uses. Any tweaks and info on MT6589T will come in handy.

Hope this helps.

How SD Cards are organised ?

Hi all,

On my out of the box ZP990 2go/32go I was unable to move applis on sdcard (no "move to sd" button).

I have added an external sd card and now I can move apps but only on this external card.

When I look /mnt with Solid Explorer I see that :

My internal sd card is sdcard1 and my external sd card is sdcard0.

Then I suppose that it's only possible to move apps on sdcard0

But I don't like this beacuse if I change external sd card what happens with my apps moved. I find more logical to move apps on internal sd card (as it was on my Samsung phones). All files linked with the phone on internal sdcard and all my datas (video, song, etc) on my external sd.

Then my question is : is it possible to make internal sd as sdcart0 and external sd as sdcar1 ?

Thank you if you can help me.
[Upgrading, Modifying and Unlocking] DustEater:
FIRST AND IMPORTANT: It's rather recommended to backup all data from the phone and external cards and format SDCARD (it's phone's space for data) and PHONE STORAGE (it's your external sdcard). Your RE-PARTITIONED storage is under INTERNAL STORAGE

1. Flash fresh ROM with MTK Flash Tool.

a) At EBR1 and EBR2 select wanted by you repartinion files. DL from here. I suggest ~2.9GB or ~7GB.

b) Select custom RECOVERY (recovery_cwm_5504_zp990.img) if you want.

c) DOWNLOAD and CONNECT your phone to flash.

2. Launch phone and download ROOT BROWSER

3. Follow this instruction to swap internal card with external card.

4. Turn off the phone, put out the battery.

5. Turn on the phone and in STORAGE settings set up like this: preferred install location ->

"let the system decide"

and default write disk ->

"phone storage"

Now it really works like it SHOULD from the beginning.
[Upgrading, Modifying and Unlocking] jipecar:
Thank you for your help.

My problem is that I have no Windows computer (only linux) then I suppose I can't use MTK Flash tools with linux. My zp990 is rooted and I have installed CWM Recovery. My build version of ROM is 20130818-102950.

Can I do something without using Flashtools ?
[Upgrading, Modifying and Unlocking] DustEater:
I dont know about any TOOLS for linux based systems, sorry.

But there are two solutions:

1. Instal virtual machine and install windows on it then use my instructions

2. Go to friend who has windows and do it

[Upgrading, Modifying and Unlocking] jipecar:
OK Thank you. I think I'm not out of the jail ;)
[Upgrading, Modifying and Unlocking] jipecar:
First good new. I have found a Linux version of FlashTool. For Linux users it's here :

http://www.phonandroid.com/forum/installer-flashtool-sous-linux-ubuntu-fedora-etc-t28048.html

I have installed but not yet tested with the Zopo.
[Upgrading, Modifying and Unlocking] mirchichamu:
And what about the Linux drivers? Will Linux detect MTK phones? I had a big problem in the past to connect my windows phone to Linux and that was the reason I reverted back from Linux to Windows.
[Upgrading, Modifying and Unlocking] jipecar:
As I said I have not tested with the Zopo. That will be the next step. But I'll not go back to windows if MTK drivers are out. For me Windows vanishes en 2008. In the case Linux version doesn't works, I'll probably use Vaitual Machine with an old XP that must make love with dust somewhere on a box somewhere in the room :)

I hope the MTK drivers works on XP !
[Upgrading, Modifying and Unlocking] Ninjakura:
Is there any updated O.S or any updated custom rom (kitkat hopefully)?
[Upgrading, Modifying and Unlocking] mirchichamu:
One of the problem with many Chinese phone is that there is very little if any support from them. They will update only the present version if at all. Forget about kitkat. I sent a message yesterday to zopo on official Facebook page, to release the source code so that developers have a chance to make custom roms. The reply was, "what you want"? I told them, that I don't want anything for myself. I repeated what I wanted. They replied me to contact Zoposhop... Now what you can expect from them? They don't even know what is the benefits for them if they release the source code to xda developers.
[Upgrading, Modifying and Unlocking] shikhar623:
I guess the person you have contacted was a reseller. He is Just a trader. They buy the handsets and sell them with some margin. So what I would say is, in future go for the manufacturers which release the source code. These resellers won't be able to give you any support.

Sent from TheXDApp
[Upgrading, Modifying and Unlocking] mirchichamu:
I contacted them through their official Facebook page of zopo and not reseller. The official web pages of all Chinese phones are in Chinese language. So it is very difficult to find first and if found, will be difficult to communicate with.

Hi Friends,

On my Zopo990 the external SD Card is known as SDCard0 and internal as SDCard 1. I have seen on this thread how to swap but that didn't work for me despite vstab modifications. I didn't insist because I have Linux Mint machines and I can't install Flashtool and then can't repair in case of problems (it's a pity that there is not an app like Odin Mobile usable on this machine)

Then for now my apps are on my physical external SD (a Samsung 32gb). But I've just bought a 64gb ans now I have to swap between the 32 and 64gb cards. I suppose I can't only exchange the 2 cards because I'll have problems to boot without most apps not accessible.

I have not yet received the card and I don't know if formatting will be necessary. If not, I'll copy all the 32gb card on 64gb with OTG before swapping. I think it's the most simple solution.

But If I need to format, how can I do ?

Thanks if you can help me.

No network signal

So close to attacking my phone with a hammer...

About a week after receiving my zp990, I lost cellular reception completely. I get red Xs on the signal meter, no matter if I use 1 SIM or 2, no matter which slot I use.

Here's the data:

Using the latest original firmware Zp990_20130904_163745 . The phone came this way from the store, and is not rooted.

Very rarely I do get a signal - I think it's location dependent, but not sure.

It seems like the "No Cellular Reception" problem is common with Zopos. I saw several forum posts on this for the zp990, and many posts for this on other models (980 etc).

I followed every instruction I found. Nothing helped

Only cellular is out - WiFi and Bluetooth are fine (and turning them off doesn't help cellular reception).

I tried turning off all unneeded frequencies, changing to GSM/WCDMA (WCDMA Preferred), to GSM/WCDMA (Auto), to WCDMA Only - nothing helps

Tried resetting to factory defaults, removing battery and waiting - nothing helps.

Even tried taping a paper clip to the antenna cover, like I saw someone do in some forum post. Nothing.

My APN settings are all set.

Happens with SIMs from several companies. Same SIMs work fine on other phones.

Checked it myself and at a lab. Antenna sits tight, nothing loose. Lab guys have no idea why no reception.

So disappointed. The 990 showed so much promise, but the bottom line is it's useless, and I'm left carrying my 2 old phones along with this phone-less tablet.

Would appreciate any help you might have

Thanks
[Upgrading, Modifying and Unlocking] Overheat2747:
Return it or kiss your money goodbye.
[Upgrading, Modifying and Unlocking] justkim:
can't return it. Already finalized the sale on aliexpress, as the phone was good for a week or so.

BTW - very likely it lost cell reception after a drop on the floor (not very high - 40cm or so). But as I said antenna and other internals - everything seems to fit in place, no signs of loosening, breakage etc

[Upgrading, Modifying and Unlocking] justkim:
Yes I do, but yesterday I tried the regular back and it didn't improve anything.

HOWEVER...

Yesterday I entered recovery mode and wiped cache and user data. This probably changed something, as previously I had reception around 5% of the time, and now I have reception around 50% of the time.

Still, a 50%-connected phone is still useless and from what I read in forum the problem appears on ZOPOs after some usage, so I guess even the 50% will drop lower soon.

Does this "the problem appears and grows with time" phenomenon give any ideas on what could cause it and how to solve it?

Hi.

I own a ZP990, and cant say anything bad about it. It might even be the best smartphone Ive ever seen, FOR THE LOW PRICE.

You who have a G2, plz dont compare the phones by specs only! You have to check the price too!

You can get a ZP990 for half the price, and the specs are about 70-80% compared to the G2. So, with simple math: ZP990 is overkill when it comes to the specs AND the price!
