After what @tugof and @prinxo suggested I also reverted to ROM v1.1 and now the Apps that didn't work (Flightradar24 and some public transport Apps I need) can be used. So I'm going to have to stay with this version. :p:)

Bruno, do you know, what the differences are?

One other thing I noticed when I do backups in CWM, i get the following errors:

can't open /cache/recovery/log

can't open /cache/recovery/last_log

Anything I could have done wrong? (I use the original file system layout, so only flashed recovery).

A little help

Hello, I just received my ZTE V970. I am trying to flash for the first time a custom Android ROM, I am a complete noob on this field, my last custom ROMs that I managed was Windows Phone 6.5 on a HD2, long time ago, lol....

My first problem are the Drivers, I downloaded MT6577 USB VCOM drivers from the 4shared folder, but it doesn't install. I have Windows 7 64-bits installed, this drivers aren't compatible with Windows 7 64 bits? Any toughs?

Also my phone came with a CWM Recovery Customized version, it is written ZTE-V970 Recovery v5.5.0.4, and it is all in Chinese, if I solve the Drivers problems, is it possible for me to flash the CWM Recovery from the 4shared folder from Bruno? Or simply change the language?

Any help would be appreciated.

Cheers,

Sergio

Installing 2.1, and will see if it is solved.
[ZTE Grand X V970] prinxo:
Most probably the version 2.1 will solve you the system UI FCs, but can you please post your experience with apps not working (like My Tracks and others)?

Good luck with the update!
[ZTE Grand X V970] tennyleaz:
On 2.0, any app using GPS won't work, non GPS signal can be detected.

Haven't test with 2.1.
[ZTE Grand X V970] bgcngm:
That doesn't make sense. I would agree if you compare battery life with JB against ICS, but not JB V1.1 against JB V1.0. No substantial changes were made that could lead to that.
[ZTE Grand X V970] bgcngm:
Sorry for the late reply. Here are the answers to your questions:

- I would prefer to use apktool only... First you have to install framework and then you can decompile Mms.apk, do the changes and re-compile it back. I advise you to get the stock Mms.apk and work with it as base... After all, I have already decompiled and recompiled it once and you may get unexpected issues by doing that process all over again probably using a different apktool version.

- V3.1 ROM has modified icons from ZTE, not the stock ICS ones.

Probably the lib change is not relevant in this test.

I got higher scores than you with the new hwcomposer. Check attached pictures.
[ZTE Grand X V970] bgcngm:
I have already replied to that before (here). To deodex it you have to use baksmali, then merge the output smali folder into the output folder of decompiled Mms. After that you can use apktool to compile it back, both resources and smali sources.
[ZTE Grand X V970] tlac:
It's hard to believe it. I can only imagine that there is some difference in the hardware.

But please at least check warnings to find these:

HWComposer dequeueBuffer: wake up to find available buffer

HWComposer dequeueBuffer: cannot find available buffer, wait...

Use the following command and switch screens, lock and unlock your phone:

adb logcat *:W

If you find it, you also have problem, just you didn't notice.

hi, anyone know how to make compatible with our V970, the beauty accuwaether and clock widget from samsung galaxy S3..?? :rolleyes:
[ZTE Grand X V970] Jebusura:
I don't see the complaint holding much value in my opinion. My guess is improper battery use has caused those users some issues but for me there is no extra drainage of battery in the latest ROM.

I use Wi-Fi + GPS alot and then on top of that I use a torch app at night for a minimum of half hour while playing music at full volume (because lets face it, anything less than full volume on this phone is useless lol). I run a live background (not a static wallpaper) and play the occasional game sometimes I will turn GPS off but mostly it's always on, Wi-Fi is always on. I don't make so many calls to be honest, less than an hour a day but I still have over 20% to spare at the end of the day! So unless you are on the phone a lot I really can't understand how anyone would have an issue with the battery drainage.

The only issue I would say is that it charges slow. I put it on charge while I sleep, I usually sleep 7 hours and most times it wont fully charge in that time! But I think this is normal maybe? But even then it is still enough to last me through the day without topping up on charge.

I also find it strange that the issue comes from JB V1.1 over V1.0. I think it is not ROM related, I think there had been damage done to the battery
[ZTE Grand X V970] bgcngm:
I'm glad to finally read the feedback of a user that is not complaining about battery life. :rolleyes:

Regarding the slow charging, that is kernel related and seems to plague all MT6577 devices. The problem is that when phone is connected to the charger, while screen is turned off, CPU is set at the maximum clock frequency.

EDIT: The only workaround that I know of for that is to activate Stay awake option, under Settings / Developer options.
[ZTE Grand X V970] bgcngm:
I will ask again, have you tried connecting the phone into the computer after clicking download button on SP Flash Tool? It seems that you want the driver to be installed first, but that you only get the first time it is recognized by the computer.

Appeak does not work properly

Guys, can someone be so nice and test Appeak Poker (free app at google play) It has some strange screen freezes and loops, for example it repeat some frames of game for few seconds.

I reported this to Appeak and they say I'm first person reporting something like this. I want to be sure is this my device or ROM fault. It was running very good with ICS.

Thank you !

ps: for me battery drain is same as on ICS

Appeak screen problems fixed by user tlac HWComposer package

My phone was smooth and fast with 4.0 and 4.1 just one problem was with game (Appeak poker) it was not working correct.

Thanks to tlac post link all is solved now!

It is still smooth and fast as before!

ps: as I'm charging my phone every day I can tell +/- 2h how long it can work on the battery, will check with new driver if battery works better. WIll try to use it even more today to make sure it has some impact. (if there are no errors now, and HWComposer is fixing some issues could be battery will be better now?)
[ZTE Grand X V970] pinglis:
step one in the tutorial says First of all, make sure that you have MediaTek DA USB VCOM drivers installed...these are not there

when i plug in the phone (with or without battery) a new device mt65xx preloader jumps in and out of view but does not install

if i start sp flash first then plug in the phone as described it just sits there and does nothing at all....

i have tried searching for a way to install the drivers before asking for your(s) or any other help as i dont want to brick this phone like i did the last one

thanks for your help and patience

First of all thanks for the great ROM.

brothers and sisters i am very tempted to buy this phone

i have my doubts just on 2 things

can you please give me an answer

1. is the screen good when you watch from an angle ? and is the brightness high enought ? i have read that it looses it contrast but doesn't invert colors when tilted and that it doesn't have enought brightness compared to other phones ?

2. is 1600mah battery enought? can you give me some idea how long does it last and with what usage

3. does Jellybean works good or it has some bugs i read (graphical issues , lags , big drain on battery ? )

this is the phone we are talking about right ? 140$

[ZTE Grand X V970] rufaz:
well, you can wait a little more longer for next device that will be released with better processor mt6589, better graphic card sgx540, 2gb ram, bigger battery capacity (jiayu g4). that will remove your doubt for sure. but ROM support, im not sure. :D
[ZTE Grand X V970] mite_jan:
Jiayu G4 with 2gb ram would be 280-300$

this phone is 140$

you are talking for a totaly different class of phone

i doubt any MTK6589 would be bellow 200$

anyone answer my 3 questions ?
[ZTE Grand X V970] rufaz:
well, to me, it is priced just right.. :cowboy:

now, will answer your questions.

1. is the screen good when you watch from an angle ? and is the brightness high enought ? i have read that it looses it contrast but doesn't invert colors when tilted and that it doesn't have enought brightness compared to other phones ?

regarding loss of contrast, i can say that it is there, but minimal. and trust me, you wouldnt lose anything with it. still, it is IPS.

brightness? under lowest setting, it is really dim, but under full brightness, it still can be used under bright, direct sunlight. not much problem with it. but, comparing to s3, i believe s3 is brighter (and much more saturated) :)

2. is 1600mah battery enought? can you give me some idea how long does it last and with what usage

this is very subjective and up to usage/background process.

in my case, 1600mah can last full day under normal use(whatsapp and twitter). but then, by the time i reach bed, i've to charge it. else, not enough juice to survive another day. full charge from zero will take 2hrs+.

3. does Jellybean works good or it has some bugs i read (graphical issues , lags , big drain on battery ? )

you might notice minor stutter with stock launcher. but if you use apex (comes with bruno's rom), it will be smooth. it is JB. dont worry about it. im really satisfied with the smoothness.

graphical issues? dont know what you're talking about. if you say that the gpu is underpowered. i will agree. the gpu is quite old actually. temple run 2 is still playable at mid setting.

big drain of battery? well,i dont think that it really drains that much battery. just that, with 1600mah, you will have to pamper the phone to make sure there is no heavy process running at the back. :)

note; the provided usb cable(for charger) is quite short.
[ZTE Grand X V970] mite_jan:
those were some nice answers and i thank you for that (but somehow i didn't liked your comment on the battery)

my old HTC Desire had 1450mah battery i think definitely it would last a whole day under heavy usage on internet and calls

i was really into waiting for quad cores but after seeing that cheap dual core i asked myself if it is really worth paying so much

i mean i know quad cores are better but will i really use it (i know that i will be all happy and jumping around it couple of days but after some time it will be boring :)

mostly i like the design (curly edges)on the ZTE and the smaller screen vs 4.7

all of the new phones are being made bigger and bigger

i want to use the 20$ coupon on aliexpress (26 march) so that's why i am in a rush

and as you may know not too many MTK6589 are out by now

this one catch my eye but it is too new (Cubot M6589) it has some nice specs on paper

http://www.aliexpress.com/item/Cubo...Phone-4-7inch-IPS-HD-Screen-1G/791236777.html

i am really in big dillema , i should decide by 26 march if i should buy this phone with coupon or get some quad core without coupon

i am sorry if i am going a little out of the subject
[ZTE Grand X V970] baseh:
As far as I can determine it is this phone. You can compare specs to what I bought here:

http://www.achinaseller.com/cellpho...-V970-MTK6577-ARMv7-Cortex-A9-smartphone.htm#

1. It is IPS so yes, it has a wide viewing angle with some loss of contrast at large angles but no reversal of colors as TN types. IPS panels are known for a somewhat lower brightness. I didn't compare it to other phones but it is very hard to read in full sunlight.

2. The battery is sufficient for a full day of medium usage, two days for very light use.

For navigation it needs almost continuous charging as other GPS devices (but you can charge it in the car, no?). It also heats up considerably.

3. JB works well and smooth for me (I don't play graphic-intensive games on it).

All in all with Bruno's ROM for that 140$ price I would give it a mark of 8 out of 10.
[ZTE Grand X V970] rufaz:
well, its hard to define "heavy" usage. it can be gaming, etc :P i think 1600mah is just "enough" for it to last whole day, some gaming, internet browsing, calls. i think i can get AT MOST 4hours on screen time with it. most of the cases, will be around between 2 or 3 hrs i guess? if not mistaken, mugen releases 1800mah battery for this phone. but, i think it is priced quite expensive.

i've been there, i bought this phone around less than a month ago actually. and i was waiting for quadcore and 4.7" too. but i cant hold my horses. i was desperate and gotten this phone instead. well, having mt6589+sgx540 has its own advantages, you have more processing power which means that, you can play heavy games with no issue.

regarding the design, it is quite good. but i think the charging port is placed at quite an odd place. i prefer it to be on top or bottom. typing message on this screen, i think i prefer 4.7", should be more comfortable as the words are placed a lil bit more further apart. i have too much typos on this screen size (coming from nokia e5)

well, that is up to you. dilemma, yeah indeed. i'd be feel the same too. i wouldnt go for that cubot, never heard of it. i'd go for a more mainstream brand like zte, meizu, huawei, xiami. at least, they have reputation.

---------- Post added at 09:23 AM ---------- Previous post was at 09:18 AM ----------

1. hard to read under sunlight? tried to go for full brightness? i set my brightness to automatic, in my case, its not an issue o.0

2. apart from that, while charging the phone will run at 1ghz while the screen turned of. as bruno said, this affects all mt6577 devices. kernel issue. but if the phone is shutted down and charged. no such issue if not mistaken.

3. indeed. with bruno's support. it is priced very reasonably.
[ZTE Grand X V970] mmichal2:
All graphic issues can be fixed by new driver prepared by user tlac, phone will work smooth then.

After 4-5 hours using internet (via wifi) I have to charge it every day. Same is result is with ICS and JB - no difference in battery life for me.
[ZTE Grand X V970] baseh:
1. It is on automatic and I verified that it goes to full brightness under sunlight. Same with Lux Lite.

Maybe because I keep on the screen guard (it has no Gorilla glass, you know) it attenuates the brightness.
[ZTE Grand X V970] rufaz:
what graphic issue? :confused:
[ZTE Grand X V970] mmichal2:

[ZTE Grand X V970] bgcngm:
ROM support? :p Well, it's something that people in general tend not to value that much. However, when users get a first contact with custom ROMs, the feeling after all is that support indeed is important... specially in these Chinese smartphones which don't get as many regular updates like other brands such as Samsung or LG.
[ZTE Grand X V970] mite_jan:
it is very dissapointing not many developers work on these phones becouse they get some cheap deals with contracts and don't want to risk with chinesse phones

but i think there is always someone who will try to make custom rom for every other phone like bgcnmg did (probably there are some chinesse firmwares we don't even know)

let me torture you more with my problem

Newman N2 - experience, thoughts ? (or should i wait for Jiayu G4 2gb 3000mah, but who knows when it will be instock and at what price, that's why i don't want to wait)

i have never used 4.7" phone and i am scared it will be too big for me

it is a little more than my budget but i may get angry and buy it

so basically i am torn between the cheapest/good MTK6577 phone and MTK6589 phone which will be more priced

want your opinion , i am undeciable
[ZTE Grand X V970] bgcngm:
I'm sorry, but I have to say it... if you want to start asking for opinions about other phones, this is not the correct thread to do it. First of all, because it is only related to ZTE V970 and secondly because users looking at this thread are the actual owners of the phone and probably don't have any of the phones you're mentioning. You are totally aware that MT6589 is the newly released SoC from MediaTek, the first phones based on it are now starting to appear into the market, but let's not discuss that here, please.

[ZTE Grand X V970] bgcngm:
Maybe... I have been really busy lately at work, but I still wanted to have a look into the bug of the Messaging app. I may try to have a look into ZTE V987 (MT6589) ROM to check if there's something good that can be ported over and hopefully I can manage to get Android 4.1.2 running on V970.

As for the battery issues that some are referring, that's not an issue for me. If you have a read at some of the latest comments, some users say the battery consumption on JB ROM is the same as when ICS ROM was installed. What people should understand is that the official ROM from ZTE China is based on ICS. This new JB ROM was not officially released for this model (V970). Basically, it should be considered as a bonus because it has been ported over from ZTE V970M Indonesian model... and users should be happy that it is working considerably great out-of-the-box.

I have installed the game, but didn't play too long so I couldn't notice any graphic issue.

Re: [ROM][02-03-2013] ZTE V970 (MT6577) custom ROMs (ICS / JB)

Hello, my phone is a V970M, can I flash your ROMs without problem?

Also, this phone seems to have 512Mb of ram (both Antutu and the android memory manager report about 470mb of total ram), isn't the MT6577 chipset supposed to have 1Gb of ram? It is a MT6577, I've confirmed that with Antutu as well.

as far as i know, v970 has 2 version, 512mb ram and 1gb ram. probably yours is the 512mb one. the one in indonesian market is definitely 512mb ram.

Hi Bruno,

I like you rom very much.

But what happened to me:

I am little bit confused. I have installed your custorm JB 4.1 V1.1R2MOD on my ZTE V970 without problem (your cwm recovery 6.0.1.2 is installed as well).

Then I flashed mbr, ebr1 and recovery to repartition internal memory of my ZTE V970. I did not applied disable_internal_sdcard.zip through cwm recovery mode as there is update of 17-12-2012 stating that there is no need o install disable_internal_sdcard.zip. I don't know if I should...

Result is: Now I have large internal partition of 2,5 GB, but the phone doesn't see my external sd card (which in working in another andoroid phone). Even in cwm recovery I cannot see external sd card, so I cannot install disable_internal_sdcard.zip if it is needed.

What should I do.
