OK, if you haven't done it then that's definitely the problem.

The method will vary according to what file explorer you use.

I use ES File Explorer. If you open that app, press the menu key to display the list of options on the left. Next scroll down to the 'root'. Turn root on, then press the text 'root explorer'. On the menu that opens, press 'mount r/w', then in the next menu change 'system' to rw. Make the changes you need and then reboot.

Thanks Mite. Beware possible issues with SD card compatibility and KitKat. Unless Jiayu have any implemented a hack, you will not be able to write to the microSD card in certain situations. For example, if you wanted to back up your internal SD card to the microSD card you cannot simply drag and drop the files in the usual way. I'm out and about at the moment. If anybody wants more info I'll post it later. Back up your phone BEFORE you flash the new ROM in case you want to revert :)

hi i have just downloaded this official 4.4 to my phone using jiayu.es app can i install it by flashing it with the app or do i have to do it on my computer using flash tool thanks
[Device Reviews and Information] Ouzo:
You need to use spflashtool. This is indicated by the text within the Jiayu.es app.
[Device Reviews and Information] mite_jan:
i have no idea how that app works

but i am guessing that if you can flash it via the app it would need to boot into some kind of recovery

i think the official 4.4 is just for Flashtool

You have to use SPFlashtool. The instructions are right there in the app ;)

Good post !! :cowboy:
[Device Reviews and Information] mite_jan:
could be yes , original rom ported from chinesse dev just included gapps from russian dev

if you like the naked look of android try it

i would still go with this one based on official kitkat

http://www.needrom.com/mobile/20140704-kitkat/

just some people are having problems going from JB to KK and ending in bootloop probably becouse the partitions needs to be changed so this can be done either if you flash kitkat from flashtool and then the custom rom from custom recovery or there is some patch that makes the repartitioning so if you flash this you wont need to flash the KK from flashtool but directly put the custom firmware after the patch

http://www.mediafire.com/download/g6r1ast7fp739eg/g4s-DiskMan.zip

there is also a lenovo port from the same chinesse dec that look nice (requires the patch i mentioned)

mite_jan,

if i understand you right this is the correct procedure:

1.boot in TWRP or CWM recovery and do all wipes

2.install g4s-DiskMan.zip via TWRP or CWM recovery

3.after installing g4s-DiskMan.zip DO NOT REBOOT and installing this rom http://www.needrom.com/mobile/20140704-kitkat/

Is that correct?

Hi,

Im seriously thinking of buying the phone.

The "best" version would be with the 2GB RAM, MT6592 cpu and 3000mah battery? anything else I should think of when buying?

My only consern is the camera, ive read its bad. How bad is it. Im coming from Samsung Galaxy Ace and Samsung S2 and was pleased with boths camera. Can anyone make a comparison of the G4S Camera with something?

When the phone released, I read that there were many software bugs, apps crashing etc. How is it now? How is the phone overall, is it fluid, I mean do I sometimes have to wait a few seconds for a app to launch or it mostly launches instantly?

Any feedback is appreciated! Thanks!
[Device Reviews and Information] Ouzo:
There's quite a lot of info in the thread already if you read through it.

I haven't tried the latest official KitKat ROM, but in the official Jelly Bean ROMs various bugs, as outlined in my opening post remain.

Facebook and WhatsApp apparently work OK.

GPS accuracy has not been fixed. Lock times vary.

The camera is subjective in some respects, but from my point of view it is inferior to my old Note 2 and my HTC Sensation. It is not a bad camera though, just don't expect it to match current high end smart phones. Don't forget that your S2 was once a very expensive high end phone.

The phone is quicker than an HTC Sensation and Note 2. It's very zippy - fantastic if you consider the low price. Buy the 2GB version.
[Device Reviews and Information] chalimoja:
Totally agree with [MENTION=715104]Ouzo[/MENTION] Its a pretty solid phone and the Camera is also good. The main issues that the phone has can be solved with software updates I have tried almost all ROMs I could find for the phone and one of the best was a MIUI ROM which had amazing sound quality, totally different from the stock ROM but went back to stock since I could select which card to use 3G on, plus the camera was pretty bad compaired to stock ROM. So basically the hardware is solid just small issues with software that can be solved with updates.

I have done camera comparisons between the G4s, original iOcean X7 and original G4 and its definitely better than the G4 but almost a draw between it and the X7 but it does win on macro shots and macro video. I would definitely recommend the phone. And yes the battery life is simply amazing with the 3000mah battery!!

Will be trying the Kitkat ROMs soon.....;)

Wat about the gaming performance?are games like amazing spiderman 2,fifa 14,arkham origins,modern combat4,asphalt 8,GTA sa,real racing 3,nova 3 ,ganngsta vegas,gt racing e.t.c able to play at favourable fps in high/medium settings? I know you said that its roughly 2/3 of galaxy s4..but the s4 is 1080p and this is 720p..any advantages there?

Would really appreciate it if anyone would post actual fps with any of the above games on their best settings...u can use fps meter(playstore)

Also anyone tried ppsspp on it?

Finally,the new upcoming modern combat 5 was to be optimised for the mtk6592...is it safe to assume that future titles frm gameloft will be too.?

Epic Citadel benchmarks at 59FPS on high settings (ultra high unavailable).

Modern Combat 4 is generally smooth, though the opening beach scene is noticeably less smooth than my Tegra 4 equipped tablet. Settings in Modern Combat 4 seem set to high.

MC3 is smooth throughout.

Shadowgun is mostly smooth with a noticeable slowdown in the level with large halls and moving platform.

Epoch is smooth. Epoch 2 slows slightly in some very busy sections.

Dead Space is very smooth.

Performance is less than Samsung Galaxy S4 in real terms, regardless of the fact the Jiayu is pushing around half the pixels.

Can someone please help me flash the updated 4.2.2 rom to my G4S?

I have flash tools and got the room from needrom.com. When I conntect my phone with no battery nothing happens.

Also when I plug my phone in it says there is a problem with finding drivers. I downloaded a driver pack from JIAYU es site but not sure what to do from here.

Thanks
[Device Reviews and Information] vladata:
look in your device manager for any drivers missing, if that install one of this https://mega.co.nz/#!aIozRJhC!P5B-XflTCKmh-hR_pdgfQN7vSyyujfLSu5NJeXn4WEc then continue the procedure
[Device Reviews and Information] Ouzo:
Head over to YouTube and search for 'adb vcom' and a number of video tutorials will be available.

If you are unsure how to install drivers, please be very careful about how you proceed. Before you flash any ROMS, please make sure you make a full backup of your phone in case anything goes wrong. To make a backup read about how to install MTK droid tools. This is a different tool to SP Flashtools. Please read/watch tutorials before starting. There is no rush, especially as Jiayu have not released a perfect ROM yet.

Drivers

Try the drivers I have attached also make sure to use usb ports on the back of the computer not the front. Another tip, once you connect the phone to the computer and you hear the connection sound immediately connect the battery, thats what works for me. Wothout the battery the phone will simple disconnect and no firmware upgrade will work. Good luck! Sp Flashtool isn't the best, it can be a hit or miss sometimes but once it works it will work most of the time.

Hope you removed at least the trojans in this version??

I didn't feel well, even after removing them, and I am back on stock 20140410. So I had the opportunity to compare the GPS quality between those 2 ROMs. 0609 had a much better GPS! There is a clear difference and it would be nice to find out what causes it. Can anyone help with that?

I didnt use stock 0609, but this deodexed one - so I don't know if the stock version had the better GPS as well:

[Device Reviews and Information] Ouzo:
Thanks, but that's not what I mean. For example, when using an offline sat nav app like Co-pilot the G4S struggles to accurately display where you are whilst driving. It is common or a satnav app to place you on an adjacent street, even if you ate driving in the countryside.
[Device Reviews and Information] Doman:
I've done a KitKat update:

1. GPS doesn't feel much better for me. The fix is quick but accuracy is beyond the expectancy. It can still be used for navigation, yet I wish it is improved in the future.

2. The battery seemed to drain very fast in the begining (like 10% per 10 minutes, but later on it slowed down).

3. There was an anoying crash loop when screen rotation was disabled, but it is apparently gone after launcher change. I use Holo Launcher HD.

4. Is there any way to disable "App permission management" icon from the notification bar? Other the disabling the option totally of course ;)

I'll post more observations later on.
[Device Reviews and Information] mite_jan:
1.i think that gps is fixible in every rom if you know how to , so i am not concerned about this and wouldnt call it a problem just needs configuring

2.probably battery is not calibrated well give it some time and it should start discharging more accuratelly , or try to delete battery stats

4.try disabling then enabling

how is the camera , any new option

ram usage on clean boot?
[Device Reviews and Information] Ouzo:
On NeedROM it states that the microSD card can't be mounted at all in KitKat. That's a pretty annoying bug if true. Think I'll wait until Jiayu release a better version.
[Device Reviews and Information] Doman:
Mine SD is mounted :) No problems with that at all. I think the bug is for 1GB RAM version (G4L or something).

About the GPS there is still 1 hour difference bug between local time and GPS reported time. I wonder if the fix for that can help with the accuracy and even more who can fix that, phone or chipset manufacturer.
[Device Reviews and Information] mite_jan:
that should be for the G4SL i think
[Device Reviews and Information] Doman:
[MENTION=4230033]mite_jan[/MENTION]

The camera looks all the same. The same app layout, smile recognition added, a few other options... nothing realy important. The quality looks the same, but I did not much test and comparisions. The one thing has not changed, unfortunatelly for me. "Torch flashlight" still flashes instead of lightning still (in Pro Capture as example).

I haven't check the RAM usage on clean boot, sorry. No this info is pointless as I have a few apps installed already.

EDIT

One more issue - builtin auto brightness control. Still doesn't work as I wish to. But it was quite the same on rom 4.2.2. It doesn't adjust well to the light conditions. Especially noticible in very dark places (at night, it doesn't set at lowest brighness) and very bright places (outdoor at sun, it doesn't set at the brightest level). I think I will have to go back to Velis Auto Brighness app, where you can setup your own brighness levels.
[Device Reviews and Information] mite_jan:
i dont even use the autobrightness it drains the battery faster and that high percentage android process is caused by the autobrightness

yeah velis auto brightness is a nice app to configure it

ram usage should be around 1gb i think , i am not sure if there is a way to reduce this

also what app are you using for disabling apps at startup

i have tried couple of apps but they all work differently

startup manager , autorun manager
[Device Reviews and Information] Doman:
I don't use any startup manager, but I've seen there is a builtin option for that under Settings\Security.

What is also new the battery stats are not erased after reboot or even battery remove.

[Device Reviews and Information] Doman:

I cannot find such an option, under Sound (notifications) either. I can live with that, but I'd rather have it disabled. It causes a strange sound at the begining of a call at the other side of the line :)

About the RAM I use to have a 1GB phone and it was a problem for me as the phone used to clean the memory all the time. It was a real bottleneck and it caused most of the slow downs. That is why I've bought 2GB RAM phone and I do not bother about the free RAM at the moment. I don't need to have 1GB free. 100MB free will become a problem for me.
