Hey all,

Is here anyone who can help me install the new KK rom please? Like i did with my last phones, i copy'd the zipfile to my sd card but in recovery my g4s doesn't seem too see the file.

First i tryed to download the original zipfile from China original site but that was gonna take +13hours for 498 MB, so i used the link to the polish site(from jiayu). There i downloaded the file

but was a .rar file. I just changed this to a zip and to be certain i put both rar+zip on my sd card but phone can't see them...

I still have original recovery on this phone and didn't do anything else untill now with other ROM's. So actually he is completely original :)

Please help me :x

Best regards Roald

If it's an original factory ROM it has to be flashed using SPFlash Tools from a PC, not from recovery.
[Device Reviews and Information] RoaldVdB:
Thx for the reply,

i do all what they say here: http://androidxda.com/flash-stock-rom-using-smart-phone-flash-tool

but nothing seem to happen, i also have a newer version then showed on the printscreens.

But when i hold vol down, nothing happens, seems he can't find my phone :'(
[Device Reviews and Information] Ouzo:
Have you definitely installed all the drivers on your PC correctly, especially the vcom driver? Check control panel/hardware/device manager to look for the vcom driver.

There are several versions of flash tool. From memory there are those that start 3.xxxx which are SP Flash tool and those that start with 5.xxxx which are MTK Flash tool and have a newer looking interface. (Do not get confused with MTK Droid Tools which is a third, completely different tool).

Also, don't forget to take the battery or as instructed. I actually left mine out through the flashing process but I've no idea if that's OK.

edit: seems my device always disconnect after 4seconds for some reason...

Help this noob plz :'(
[Device Reviews and Information] Ouzo:
Sorry, I haven't seen that error before. It looks as though you could tick Firmware Upgrade instead of Download, but I'm not sure.

Have you rebooted your PC since installing the drivers? That might help.
[Device Reviews and Information] RoaldVdB:
I rebooted my pc, even tryed on another pc now, and when i do firmware upgrade it is this what happens...

View attachment 3046081
[Device Reviews and Information] Ouzo:
Sorry, I've never seen that error message either. The only error i had was becase i had not deleted the Chinese characters from the folder where i extracted the firmware to.

Is it possible the firmware you downloaded is corrupt/damaged? Was there an MD5 value for you to check the integrity of the download. Hopefully someone else will be able to help.

You could try visiting chinaphonearena and asking there too. There is also a lot of info on gizbeat (linked to China phone arena).
[Device Reviews and Information] RoaldVdB:
I think i got it, i tryed again with the 5.xxx version of flashtools, did there firmware upgrate and he is doing it at this moment, no error there...
[Device Reviews and Information] Ouzo:
Cool, fingers crossed :)
[Device Reviews and Information] RoaldVdB:
It's istalled, but does seems slower then original ROM and i have a really BIG problem...

I have taken a back-up in recovery before i installed this ROM.

After install this ROM did a complete wipe of internal and external SD card so i lost ALL my photo's now... There were photo's of the birth of my son on

and many other importent one's...

I can't find the backup file anywhere so also not my pictures...

Can someone help me with this bgger issue plz ...

Best regards Roald
[Device Reviews and Information] Ouzo:
Where did you save the backup to? Normally the backup is saved to either the internal or external SD card, so if you wiped the phone without first moving the backup file then you deleted it : ( I'm not sure what version of recovery you use, but I don't think photos would be saved. It's normally the system image etc that is saved.

Anyway, don't do anything more with the phone at all. Take out the SD card. Download a programme called Recuva for your PC, then plug in the micro SD card to the PC using an adapter and scan the card to see if any data can be recovered. You could try plugging the phone into the PC in USB mass storage mode and scan the internal storage for files to recover too.
[Device Reviews and Information] RoaldVdB:
I just used the recovery that was on the original g4s and did the back-up in recovery, he didn't ask me where to save the file...

I see that my external SD card is wiped completly, all memory is availeble and intern sd i can use only 9.5gig from the 16Gig, so maybe there i can find something on , but don't know how, is internal SD card...
[Device Reviews and Information] Ouzo:
OK. Don't do any more with the phone. When you formatted it the data is still there, it's just you deleted the record of that data, just like doing a quick format of the hard drive. Don't do anything more with the phone at all. You don't want anything to write to either the internal or external memory at all. Download Recuva on your PC, plug the phone in to the PC in USB mass storage mode and search for files that can be recovered.
[Device Reviews and Information] RoaldVdB:
I installed alrdy my app's i had before, but doing scan right now.

Thank you verry much! I hope i can find them... and if i find them. And if i find files, where can i find the photo's and recover them?

Edit: I found some pictures , but only 10 from 150 orso. Couldn't see a backupfile, what should be the name off the file?
[Device Reviews and Information] Ouzo:
If you took the photos with the Jiayu then they would have been saved to the internal storage. If you've already installed your apps I doubt there will be much left to recover :(

If you install another ROM, backup anything you need to save to a PC or perhaps the micro SD card. For example, any photos stored on the internal memory, any downloads or music. I'm still not sure what recovery you have installed, but if you use Clockwork Mod (CWM) it will usually create a foder on the memory card called clockworkmod in which you will find sub folders and backup files themselves, such a boot.img, recovery.img etc. If you need to format the SD card again, save it to a PC, or an external flash/hard drive using a USB OTG adapter (this is my preferred method).
[Device Reviews and Information] RoaldVdB:
Well i didn't wan't to swap the sd card, sp flash tool did it with updating to the last KK original ROM :'(

I'am rescanning the SD card again, hope to find more images now or some other...

Thank you for the help!

Best regards Roald
[Device Reviews and Information] RoaldVdB:
Are the other people who also installed the new original KK 4.4.2? On main screen there is a really BIG music player that isn't beutifull and can't get rid of it. Does someone know how to do this?

Or is there another topic about this issue?

Best regards

Teamforce news?

Hey guys. Anyone has news of teamforce's progress on a G4s KitKat custom kernel? Will we ever see one seeing as how their site went down earlier today? Cause their 4.2 custom kernel is the only thing that made this phone perform like it should in my opinion. Would be great if we had an update on the current status.

Thanks in advance for any answers.
[Device Reviews and Information] SkubiDoo:
Try to ask by needrom.com, but in my opinion project is dead
[Device Reviews and Information] ricain59:
Try this: http://www.needrom.com/download/chilapos-rom-2/
[Device Reviews and Information] RoaldVdB:
This ROM is really better then the official ROM?

Do you all use Nova Launcher? On Needrom theu told me to install it. Is it much better then the standard and what is different?

Best regards Roald
[Device Reviews and Information] Ouzo:
I don't know about that ROM because I'm still using stock Jelly Bean, but Nova Launcher is great. I bought the Pro version. It is very different to the stock launcher. You can choose the 'size' of the home screen (how many icons wide and tall). You can assign functions to a gesture on the home screen. For example, I have it set so swiping down the screen brings down the notification bar. The dock bar can be swiped left and right independently of the home scree. You can hide the notification bar nd dock if you like. You can install themes that change your icons. You can assign new icons individually if you want. You can create a second action for each icon (an upward swipe). It is extremely customisable. Search XDA for more info, or look on YouTube for videos of what it can do. There is a free version to try. There are also other launchers such as ADW and Zeam of course. Try a few and see which you like best.

Here's my simple home screen which does everything I need on one page...
[Device Reviews and Information] ricain59:
The rom is based on official but the official no have recovery and this yes. I have this rom and no problem yet. I haven't install nova launcher sorry.
[Device Reviews and Information] RoaldVdB:
Hey all again,

Do you all have also problems with the battery in this rom? With the original 4.2.2 my battery lasted 3-4 days. After installing this Rom my battery is empty after 1.5days... And this and original rom my bluetooth is constant on and data also.

With this rom the last 50% is even lost during night. Last night i had 53% battery, this morning my phone was death...

Is there a solution for this?
[Device Reviews and Information] JeeHaa:
I am running Chilapos 2.2 and battery life is awesome (actually it has been similar with all ROMs so far): I get 4 days with 3G on, 3h screen time, light usage, wifi on every now and then, no BT though. Maybe some app that is causing your problems. What do the battery usage stats say?
[Device Reviews and Information] RoaldVdB:
Dear,

With this ROm my battery usage is:

33% Cell stand-by ... O.o

32% Phone idle

27% Google services

then some small others...
[Device Reviews and Information] JeeHaa:
27% Google services definitely does not look normal.

There are many causes (Google it), and a factory reset may help.
[Device Reviews and Information] javserher:
Before I changed to a Zenfone 5,I have had a Jiayu G4 for almost a year (T model, with MTK6589T CPU) but the USB plug charge broke and I need to buy a new smartphone. Other people I know have suffered this problem and I think Jiayu should take care about this but it is a quite good phone,specially this updated model with the 8-core SoC
[Device Reviews and Information] RoaldVdB:
Dear,

i specially think that the phone idle and Cell stand-by is really high... I checked google services also and no problems there...

Maybe i should also recallibrate my battery now? And how i can do this best because phone isn't rooted now...
[Device Reviews and Information] Ouzo:
You do not need to do anything to recalibrate your battery. Just use the phone. There is a huge amount of information about battery life all over XDA ;)
[Device Reviews and Information] RoaldVdB:
Checked some posts and will indeed not recalibrate the battery,

But after shutting everything down of google services (what i found on forums) it still drains 30% battery... All location findings are off, automatic checking mail, gps...

Nobody else got this problem after upgrading to KK original?

I could use my phone 4days on original ROM, Now on KK only 2 ... :'(
[Device Reviews and Information] indiffereddie:
Is your phone always awake? Try installing setcpu, or go to battery, and see if your phone is always awake
[Device Reviews and Information] alicepattinson:
Thanks to this thread/review. It still depends on the user. ;)
[Device Reviews and Information] RoaldVdB:
Lost just something new, my phone had +-50% battery and in 30min he just shutdown because battery is empty...
[Device Reviews and Information] Ouzo:
Backup all your data, remove your memory card and do a factory reset. After that recreate your account on the phone but don't install any apps, don't put the SD card in, just use it for a couple of days and see how you get on.
[Device Reviews and Information] Ouzo:
Thanks :) I've honestly been meaning to rewrite the opening post to reflect everything I know now, but I've developed a bit of a love hate relationship with my G4S. Love the battery life, screen, general performance, the small form factor etc, hate the GPS issues, wish it had backlit capacitive buttons, wish the camera was better, wish Jiayu had a better update system for people outside of China (I'm still on Jelly Bean because in concerned about reports of malware in KK ROMs and inability to return to Jelly Bean for some).
[Device Reviews and Information] zohirha:
how could I go back from 4.4 ROM to 4.2 ROM without losing screen calibration

I can't manage to return from v6 stock mode 4.4.2 kitkat rom

To offical 4.2 jb rom even when I format the phone and flash a 4.2 rom by sp flash

I lose the screen calibration

Is there a way going back to jb rom ?

Thanks for help
[Device Reviews and Information] Ouzo:
You need to use the TeamForce patch, also available on NeedROM or their own website.
[Device Reviews and Information] zohirha:
install patch problem

In order to use these patch you should have a recovery

But after flashing 4.2 rom there is no possiblity to get into recovery mode

And I can't download a new recovery because there is no normal touch

In the 4.2 rom that I have flashed so how can I use these patch??

Thanks
[Device Reviews and Information] Ouzo:
Possibly reflash the stock 4.4.2 ROM, then flash 4.2 recovery? I don't really know because I'm still using Jelly Bean.
[Device Reviews and Information] jaw2floor:
Smashed my G6, now thinking of buying this as a replacement. I see that the main downsides of this are the GPS and camera? Does anyone have sample/raw photos and from the front camera also?
[Device Reviews and Information] Ouzo:
The rear camera is OK, no more. It's probably worse than your HTC One X in one ways. Macros come out nice. The front camera is awful. The GPS is way behind Qualcomm chipsets of the era of your One X. Lock can either take a few seconds or several minutes. Accuracy is the man issue, not so much in route tracking apps like Endomondo, but in sat nav apps like Co-Pilot. If you use a phone for sat nav in a car every day, do not buy this phone.
[Device Reviews and Information] danb1974:
Is there something really wrong with headphone audio on this model?

When I plug in the headphones (music headphones, sennheiser 5xx series, no cheapies), for a couple of seconds there is a faint series of fast beats

Music / radio lacks bass and stereo imaging seems somehow lacking. Overall audio quality is really bad, not just "no hifi chip inside" bad. Radio app has no equalizer options that I can find and some music eq app has no effect on radio only in music player. It sounds 10x worse than a cheap noname mp3 player.

Running latest jiayu.es kitkat rom
[Device Reviews and Information] Ouzo:
Yep, hence why I said the audio quality isn't so good in the opening post. Some users say Viper Audio improves things greatly, though I haven't tried it yet.
[Device Reviews and Information] mite_jan:
i installed latest international version of kitkat and everything is working fine but the battery accuracy is just not right for me :)

gets stuck at some points and when it comes bellow 15 percent in couple of minutes my phone is dead
[Device Reviews and Information] danb1974:
I'm more tempted to completely avoid headphone output, at least if no real solution comes. It sounds bad enough to make me think it's a bug and no amount of equalizer will make it right, just less worse

- get the smallest usb sound card there is, but a decent one (for example based on the pcm27xx/29xx line of chips by burr-brown now texas instruments). There is a model on ebay that does not even have a box and can be wrapped with heatshrink tube.

- connect it to phone via usb otg cable

- get a media player that supports usb sound cards (only lollipop has native support for this)

Found such a player (non-free but not overly expensive), tested with an usb dac I have, works like a charm. Just that my dac is not small enough.

At some point I remember seeing such an usb sound card embedded into the cable itself (electronics were in a "bulge" somewhere on the cable) but can't find it now
[Device Reviews and Information] Ouzo:
I think someone in this thread is already using USB output in conjunction with a particular music player app in the play store. Have a quick search for a couple of posts about it.

The app is USB Audio Player Pro....

G4S reception problems

I've got my Jiayu G4S 6 weeks ago. I had G3 before, was really happy with it, gave it to my son.

G4 was really good at the beginning, although caller display problem surprised me - G3 didn't have it. My wife got a new Jiayu G5 - the same problem.

But about 3 to 4 weeks into use the G4 reception started to deteriorate. If earlier I had 4 bars where my old G3 only had 3, now I loose reception in places everyone else has it, especially bad it's indoors.

i wonder if anybody else ran into similar problem?
[Device Reviews and Information] Ouzo:
Is it possible there is a problem with the contacts between the main board and the antenna. The phone antenna is the black strip at the bottom part of the phone. If you're desperate you could remove the eight screws and take the inner cover off to have a look. I guess you could try gently squeezing the bottom of the inner cover to see if that helps improve the signal first.

Slide Quick

Hi,

there is a toggle named "Slide Quick" in the last international rom, does anybody now what is it supposed to do?
[Device Reviews and Information] ricain59:
Hi,

i've problem with my battery, my friend help me and use battery calibration from play store but the problem is same.

The battery discharge but the percentage is more???? How resolve this.

Sorry for my english.
[Device Reviews and Information] a123xxsp:
You don't resolve this, its about the battery quality mainly (i've seen in it in Samsung batteries too but not that often), you have to learn to live with this issue or buy a new battery.

Does anyone knows what "Slide Quick" is?
[Device Reviews and Information] petebetros:
Yes my missus phone does that too sometimes. Not too fussed with it as the battery is a beast AND removable so if that one goes tits up just get another :)

Have to say I'm really impressed with this phone - got one for my mum too.

Was copncerned about the poor GPS and initially started fiddling with the phone settings, tweaks and foil aerials. Got fed up in the end and bought a cheap bluetooth GPS receiver from eBay and well happy now. Phone GPS is fine if you just want to locate yourself, as that works, but once you start moving it is awful, which is where the external receiver comes in and now sat nav is no problem.
[Device Reviews and Information] Ouzo:
I used to have a Bluetooth GPS for my old HTC Touch - happy days!

The sad thing about GPS with the G4S is that it's the first phone I've ever owned where the battery life is so good I can cycle for hours with the screen on and Co-pilot running without worrying about having enough juice to reach my destination. For me, that makes it really frustrating that accuracy can be so poor. If only Jiayu had got the antenna design right.

I still think the G4S is fantastic too. Recently I've been running an emulator to play an old Star Wars PC game using very high texture settings and it runs it just fine. It's a real little workhorse. The screen is still fantastic in comparison to many more expensive devices where whites look washed out and yellow, but on the Jiayu they are nice and crisp.

going from dalvik to art is like day and night

noticable speed

bad thing is that some apps are still not compatible with it but you can always find replacements
[Device Reviews and Information] Ouzo:
I must be the last person with a G4S still running Jelly Bean :)
[Device Reviews and Information] parask82:
Nah I am too :P only because of the Team Force Kernel though. And from what I see at NeedRom the KitKat version is out so I will be trying it soon. Will post impressions as soon as I get enough time with it for anyone interested :)
[Device Reviews and Information] LuxZg:
Could you pleease link to that BT GPS, since you're satisfied with it I'd get one for longer trips. Thanks :)

Nope, I'm still on Jelly from jiayu.pl that I've installed on the first day. OS and apps all work fine so I can't make myself do all the work :D waiting for LoLlipop, hehehe :)))

Edit: oh, and remember that battery capacity varies with temperature, so if outside is -5C and in house it's 25C than you'll see slight variations on battery % on phine as well. Just a thought! :)

That's the one I got, doesn't seem to be any left but that seller was listing new ones everyday before Christmas so he may start again.

Having said that, any one would do I'd guess.

Switch GPS receiver on, turn bluetooth on on phone, start Bluetooth GPS app on phone and press connect. Done. Use maps as per normal.
[Device Reviews and Information] LuxZg:
Sounds great for just 7GBP, will search for it as soon as I get home. Thanks!! :)

Btw, how is your battery holding when using phone with BT GPS? IDoes it draw a lot more power because of additional load from BT?

Hi,

what is the difference between this ROM and Chilappos? Are the storage changed or is SD Card external storage and the internal storage the internal?
[Device Reviews and Information] mite_jan:
Deodexed so xposed works and it works pretty well finally when i press double times on status bar it goes to sleep instead of smaahing it couple of times on previous roms, storage is normal like on stock rom

On previois jb rom i noticed stutter on go locker animations but not here

Also swiftkey keyboard pops out quickly, not sure if it is a kitkat thing

Chilapos is like the stock rom, this is on a different base more like pure aosp

I would go with chilapos only if i use art but i have tried it and i figured that i cannot live without gravitybox

Jiayu S3

I`m thinking about Jiayu S3. It has GPS, Glonass and Beidou. Beidou i think isn't working in Europe.

And i believe, that S3 GPS will be much better than G4S
[Device Reviews and Information] Ouzo:
5.5" is a bit too big for me. Very hard to use one handed.

Mediatek have claimed to fix their GPS for the last two generations of SoC, so I think i will wait and see some evidence of it working properly. I think I need backlit buttons and MHL back too. I miss them.
[Device Reviews and Information] pozzeco:
S3 would be for my wife. I'm still happy with my G4S until summer and cycling season :)
