I don't understand your case completely, but the battery percentage reporting in our phone is buggy and it differs how wrong between phones and batteries. For example, my phone reports slow draining until ~50 % and then it suddenly drops 16-20 % rapidly. I know if my phone is about 50 %, I have to spare with the battery until I can recharge it.
[Android General] jurlerrod:
The problem is that the OS didn't read the real percentage of battery. The only % is good is the 100%. I've got an app that shows me % by reading the MV of battery. The life of battery is about 12 o more hours, so i thing it's ok. With the app that I told you, i know when battery its near the get empty. But what i want is that the OS read it correctly . i thing it's a driver problem ....i have 4.2.1 from needrom. Yesterday I flashed it again, because of this problem. Before flashing I format everything un CWm....but the problem persist

[Android General] kecsap:
We can't do anything with it. It is a pretty common problem for Chinese phones like ghost touches on the touch screen while charging.
[Android General] gagen:
same problem!!!!

What is the name of the app that reads the mv?

thanks
[Android General] PDPR:
I know it sounds a joke, as either myself don't understand why on earth the manufacturer did this stupid thing.

You can follow my small contributions on other XDA threads and see that I'm a serious forum member.

Please, find attached a better focused pictures, not have so much time to make the video showing the three lights, You can see that the zone I've scratched it's not precisely a circle, but a "line" I did it with an small needle. Actually, the led's position on the board is a little bit below, in the speaker's axle. You'd get more light intensity scratching there.

Hope it's clear
[Android General] PDPR:
Personally, since the beginning,I didn't do anything regarding this LED's matter, and the battery duration for me is more or less a day and a half, not different from other phones I had.

Other different thing is the bad battery managent of this phone, where we can see (and suffer) how the battery level suddenly falls a 30% or so in a while without any control.
[Android General] kecsap:
The battery duration and the quality issues are the same for all cheap Chinese phones. I have also about 1-1.5 days battery time with moderate usage. But when the LED notification drain bug appears, the battery level can fall from 100 % to 0 % in ~6 hours, even if the phone is not used at all.
[Android General] veradg:
What ROM you are using? Led Not work in my phone. ROM 4.2.1 20132703
[Android General] PDPR:
I'm using MIUI 4.3.14, (it's based on Android 4.2.1), I've not tried other ROMs before finding this.

Another finding for me was that ROMs for Zopo ZP900h or ZP910 are valid for our phones, actually this is the version I have installed now. But, as everything, there's a little and simple trick to do before flashing. If you want to try, I can help..

MIUI it's really great and are enhancing software every single week, it's worth to try it
[Android General] kecsap:
I use 4.2.1 (20130406) from needrom.

PDPR: please tell as instructions.

I also would like to ask some questions:

- Do you use dual SIM feature? Does it work with MIUI? Earlier I found big issues with this feature on other Chinese phones when I tried to install MIUI ROM.

- How long have you been using this MIUI ROM on this phone? So you have not experienced this battery drain with LED notifications at all? It is possible that the MIUI ROM uses a different kernel or at least this LED notification bug is fixed there.

- Can you post a build number or screenshot/photo about the "About phone" screen to see the build numbers, baseband version etc.

- How many languages do this ROM support? Only six (http://en.miui.com/thread-15732-1-1.html) or many?

- Did you experience any issues with this MIUI ROM?
[Android General] veradg:
If you can explain "how to" for this rom..I'd appreciate it..
[Android General] PDPR:
OK. The link is the one on the official MIUI site that kecsap mentions on his last post. On latest version developer has included some new languages at request, all you have to do is ask him for it. He has also included Gapps as older versions didn't have it. As I mention, MIUI have the policy of launching new versions every week, so I have not tried this new version.

As the ROM is for Zopo 900h/910, the only thing to do for Flashing correctly in our phone is to edit the "Updater-script" file on the ROM zip, located on: META-INF/com/google/android/ by removing the first lines until you see on the first line: "show progress..." and that's all

You must know that the boot animation is lost, probably due to is for Zopo 900, I have not find the way to fix it. You'll notice a blank screen when booting, but is not important, everything works.
[Android General] PDPR:
Sorry, but I don't use dual SIM, but it should work in MIUI ROMs.

I've been instaling MIUI roms since more than four months for two different model phones with excelent results for both.

About LED issue, as mentiioned before I didn't have that problem in the past, even when I was using official version. But as you said, this ROM may be using a different kernel. The MIUI link in your post is the correct one, please see the post to Verdag I've just sent on "How to" and the languages thing.

I´m very happy with stability and performance of MIUI versions, but as there is a new one each week, I have to say that I had to back to older version twice, But if you try MIUI you'll love it, all system apps are very well designed and smart, and there are a lot of tweaks on the standard version.

Hi everyone.

I want to buy this phone since it's only $85 at Pandawill. But I have some questions.

First - I saw few posts saying that the phone doesn't indicate battery level right. Is that fixed?

Second - Is there a problem with the microphone? Like, when you talk with someone, he can't hear you well.

Third - How's the GPS? In Pandawill's reviews someone are saying that the GPS is not quite good. I'm not looking for the best GPS, I will use it for application that tracks traveled distance and rarely for navigation.

Fourth - How many hours does the battery last? I'm gonna use it for ~ 1.5 hours listening music, 2-3 hours gaming and about 1 hour browsing. I'm not using mobile network, only WiFi.

Fifth - Is the camera good? I rarely make picture with my phone, but when I do I want them to be in focus not blurry. I saw a test video in Youtube and I really liked the quality but the camera seems to focus the objects which are close, the one that are some distance away (4 meters for example) are out of focus. Here's the video so you can understand what I'm talking about - Link. Also, what's the supported resolutions for video? Pandawill said that the camera isn't HD, but the video I posted is uploaded at 1080p and the quality seems to be that. Overall, I want a camera that shoots the things in focus.

Sixth - What's your overall impression from the phone - does it feel cheap, is the sound from speaker with acceptable quality and loud, is the sound from the headphone jack loud? How's the touchscreen, the WiFi range?

Thank you everyone in advance. I'm sorry If I'm asking stupid questions but it's hard to review 96 page thread :).
[Android General] kecsap:
>> First - I saw few posts saying that the phone doesn't indicate battery level right. Is that fixed?

No, it is the same like any other cheap Chinese phones.

>> Is there a problem with the microphone? Like, when you talk with someone, he can't hear you well.

Yes, the best to resolder the microphone with the microphone from the shipped headset.

>> How's the GPS?

For running/cycling: only Runkeeper works. (I have not checked the other apps since last summer.)

For navigation: it mostly works, sometimes goes crazy from the beginning in crowded cities, restarting the phone fixes that.

>> How many hours does the battery last? I'm gonna use it for ~ 1.5 hours listening music, 2-3 hours gaming and about 1 hour browsing. I'm not using mobile network, only WiFi.

Expect the average, 1 day.

>> Is the camera good?

Like other cheap Chinese phones. With normal lightning, it is okay. I think I never had problem with focus, expect maybe when doing close macro. I would not say the quality is good, I would say acceptable from a phone. I record 720p, I am happy with the video quality although good lightning is needed. The 12MP sensor is marketing bull****, it is just 8MP and interpolated to 12.

>> What's your overall impression from the phone - does it feel cheap, is the sound from speaker with acceptable quality and loud, is the sound from the headphone jack loud? How's the touchscreen, the WiFi range?

Look and feel: average, I like the design.

Speaker: don't expect too much, but using for calls, it is okay.

Headphone jack: one of the best things for me. I connect my phone with jack to my car radio's AUX input and my previous Samsung Galaxy phone was ***** silent with maximum volume level. This phone is much louder than that and I don't have to push the volume up on my car radio after this phone is connected.

WiFi: it is okay, similar to brand phones.

Touch screen: it is okay, I don't have the usual ghost touches of Chines phones while it is on charger, but I am maybe lucky.

Other things:

- Battery drain problems caused by LED notifications, but I don't notice is a while ago. Maybe it is fixed in JB 4.2.1 or it is just because I use the scheduled on/off functionality of the phone for nights.

- The phone restarts 1-2 times a week. I experience the same with Samsung Galaxy phones.

- The volume+power buttons are plastic with silver-like plating and the plating weared down after some months from the power button.

- I think it is just my phone, but the volume button may step the volume level more than once for one simple press. Since I use a plastic case, this problem is solved.

- I use this case for the phone: http://xdaforums.com/showpost.php?p=48351017&postcount=929

- No problems with bluetooth headsets. Sometimes it drops the A2DP connection while listening to music, but reconnects again automatically.

The phone is smooth with JB and I am still happy to own until it will last.

Need 4.4 KitKat Rom for my MTK6589T Device

I have a chinese phone with MTK 6589T processor 1.5 GHz, 1 GB RAM, GPU PowerVR SGX 544MP, 4.5 inch screen 1024x768, 12 MP camera. I need a custom KitKat ROM for my device. I tried many but did not work. Please advise me regarding upgrading my phone. Thanks
[Android General] kerlsern:
kecsap, Thank you for the detailed post.

I can work with soldering gun but I'm a bit afraid that I can f*ck up something while opening the phone or resoldering the microphone. I already broke some parts of the panel of mine ZTE U950 because the plastic is super cheap. Anyway, thank you again. I'll think for another hour about buying the phone.

PS. I ordered the phone from Pandawill (promotion for $85.99). Can you give me some directions for changing the microphone? Or I just have to unscrew things until I find the mainboard :)?

Root + TWRP

Hi!

I got this phone yesterday with b943 20130703-102720 software version. I couldn't find it anywhere on the internet :(

I can easily root with framaroot 1.6.1, no sp flash tool needed.

I can also install TWRP without sp flash tool:

1. just install mobileuncle tools from google play, after the root.

2. Download ported TWRP from the first post and copy the img file to your external sd card.

3. Start mobileuncle tools, select recovery update menu, select copied img file.
[Android General] kzkz:
I can confirm, there is a notification LED behind the screen, next to to speaker left side! With MIUI ROM it is working, unfortunatelly the home and volume buttons not :(
[Android General] kzkz:
There are new ROMs:

Port HD4-SGS4-23.09.2013 (full version):

http://files.china-iphone.ru/868PORT_HD4-SGS4-23.09.2013_max.zip

Multi language, auto update. I'm using this one. Notification LED doesn't work.

LeWa5.1_B943_JB_ROM_14.02.14:

http://forum.china-iphone.ru/away.htm?http://yadi.sk/d/3iLn1XvTHyhRn

Like MIUI, but only Russian and English language. Notification LED doesn't work.

ColorOS_v.1:

http://yadi.sk/d/lmw2P_1qHxz94 http://yadi.sk/d/lmw2P_1qHxz94

Taken as a basis ColorOS_Alternative by DiMiD - minimal changes that you twirled added minimum.

I did not try.
[Android General] jucaftp:
Thank you
[Android General] kerlsern:
Today I tried the GPS with RunKeeper and it was disaster :). I'm using the stock 4.2.1 ROM and the phone found at least 5 satellites but the signal strength wasn't very good according to GPS Test. I don't know if it's my phone but the tracked location was 20-30 meters (at some places even 50 meters) away from my actual location. [MENTION=5249680]kecsap[/MENTION] said that the GPS could go crazy sometimes and restarting the phone can fix the problem. I will try it tomorrow.

EDIT: I tried it again, without restart, and it was more accurate. Although it connects to 6 satellites, the signal strength is not very good.
[Android General] philipp900:
Which ROM?

Which ROM do you guys recommend using for the Star B943?

Is there any version newer than 4.2.1?
[Android General] kerlsern:
Stick with the stock rom, unless you're not pleased with the battery consumption. I've tried like 5 different roms and I must say differences aren't that big, but I haven't tested the battery consumption on the different roms.
[Android General] kecsap:
Recently, I repartitioned my phone and flashed the MIUI 4.7.11 from http://en.miui.com/thread-15732-1-1.html.

My experiences compared with stock JB 4.2.1:

- Every HW item/sensors work.

- LEDs work. I scratched the cover to reveal them. It is a nice additional feature for me. Light Flow can manage the LEDs with settings: Device Settings and Root (Direct Mode+Root Mode).

- The phone seems to lag more than with factory ROM. Now I removed some MIUI bloatware, freezed some apps and started to use Greenify. I hope it will help to consolidate the speed.

- MIUI has great features. I like that I can manage many settings to customize the ROM and ensure the security.
[Android General] kerlsern:
Yes, MIUI is very nice rom but apart from the cool UI, it doesn't add so much new things. You have to disassemble the phone to get the LED showing. The phone lags because MIUI is set to draw less power which mean the CPU load is lower thus the performance in menu animations. The security should not be so big concern as long you don't install suspicious apks.
[Android General] BradleyW:
Has anyone gotten anywhere with this phone, it was my first android phone that I got in 2012, I'm now onto bigger and better things and this sits in a desk drawer, but I still wonder, why hasn't anyone done work on this. I know Unix/Linux basics and Java Programming, but I don't think these would help. Is there a file the manufacturers need to provide or something because I'd love to mess around with it and wouldn't care if I bricked it.

seems I bricked it

Hi,

after following the guide in post 1 my phone went into a bootloop (flickering boot screen). At that point I had the boot and recovery image flashed and the root app installed via CWM.

When several reboots and taking battery out & putting it back in had no effect I decided to go for the recovery image also linked in post 1.

Again flashing worked fine but I'm stuck in the bootloop again.

Can anybody give me advice on what to try next and / or supply the original firmware (or any that works on this phone).

CWM menu is accessible and I also still can flash my phone via the SPFlashTool.

Any help would be appreciated,

so long
[Android General] cmoegele:
Try to use MTKdroidtools to check basics.

Some more information you can get with ddms.bat from the android-sdk tools.

If you want pm me your teamviewer id and we can have a look together.
[Android General] Stuffed-up:
Hi

I just got this phone today as my trusty Exhibit 2 finally died.

Anyway so I got the MIZ Z1 MTK6589 Quad Core version but would like to know if anyone has tried installing the TWRP Recovery as of yet & has anyone find a safe way to root the phone.

The other question is how much rom development has this phone got as i really like rootbox 4.2 but any other work would be great to know of for the future.

Thanks you anyone that can give me any info.
[Android General] cmoegele:
I´m using the TWRP and it works good.

For rooting first check your device with MTKdroidtools create scatterfile with it and compare it to the file in the download.zip

For flashing the TWRP simple exchange the cwm recovery.img with the TWRP recovery.img and before rooting make your first backup with TWRP or CWM.

At the moment there is not much Rom development going on.

The MTK6589 devices are too new and there a lots of small bugs in it to fix.

So hopefully some vendors will bring soon some updates.

Have fun ;)
[Android General] veradg:
The seller sent me a rom to try to solve the problem of the microphone and keyboard (uncalibrated or something). I have the link but I still can not download it because the server is very slow. If you want to pass the link by private message for you to see and also could you upload it to another server in case anyone else wants to try.

Hi Cmoegele

Thanks for the reply & have one more question has anyone got the 4.2.1 Android version of Rom as I'm going to ask a Dev I know on here if there's away to have Root box Rom made for this device.

MIZ Z1

Can you please do a backup of rom from MIZ? I broke my, to state that wifi is not working :(.

I did root with tutorial from 1st post, except used CWM-SuperSU-v0.98.zip (google it :) in CWM.
[Android General] cmoegele:
No need to root just readback your rom with scatterfile and spftools, if you wnat spent some time for community and your safity ;)
[Android General] cmoegele:
Please send me link and I will try ;)
[Android General] cmoegele:
Don´t know why you use other SU as described???, but with this method I rooted several MT6589 devices without any problems.

The CWM recovery itself does not change or destroy any system data, therefor I made the hint to do backup before you try rooting.

In such cases you can easy restore working system and do another try,....
[Android General] okupka:
Rooting doesnt destroy anything, my later "fixes" did. I know, my dumbness, that i didnt make backup :).

I used other SU, because that one does not work. Maybe 4.2.1 is the difference?
[Android General] cmoegele:
Ok thought it was problem of the tools.

I add some warnings to first post.

Perhaps you can contact your seller for link to new Rom, I think this could be a good starting point for our devices ;)
[Android General] okupka:
One more thing.

I have problems with foto, macro is great. Other photos are blurred.

I have read on russia forum, that it can be fixed, with some hardware fix, which i dont want do right now.

So here is software "fix":

download lg camera, settings > focus > infinity :)

I will try to contact antelife about rom, but do not give it much hope.

If I'm not wrong some spanish users are reporting some sound problems on phone calls. In case this is not a hardware fault, I think we could solve it easily doing the follow steps:

1-find out which files are related to the phone call quality and coverage .

2-Copyp them from other mtk6589 device such as ZTE V987 or Lenovo A820.

3-Flash it via cwm on our Star B943 phone.
