Flash this http://www.4shared.com/file/VwdfzhKe/recovery.html with flash tool or mobileuncle than get into recovery by pressing power button 2 seconds later volume up button. Once in recovery mount your SD card by pressing the mount menu, once mounted move zip file you downloaded to the root SD card. Next wipe data cache and davlik cache in the wipe menu. Next press install in the menu go all the way down till you find your zip file and flash it done!

screen failure

Hello, after three days using the G2 Giayu 512 Mb screen failure.

A video:

[YOUTUBE]wfhC-8RKbTE[/YOUTUBE]

had Android 4.0.4, build number: G2L 20121017-121813.

The upgrade to 4.1.2 but still the same.

Anyone have any solution to this problem?

Any idea if it is hardware or software?

It looks like hardware problem but if you want to check download mobileuncle and do a LCD test or format back to official firmware

---------- Post added at 05:13 PM ---------- Previous post was at 04:48 PM ----------

I just checked Google and I think betterbatterystats app fixes the problem.... If you have any battery monitors or any led managers delete them it should fix the problem

Jiayu G2 1GBRAM Dual-Core JB 4.1.2
[Android General] gipower:
When battery drops below 15% the red led flashes. This causes a Led wakelock and cpu hangs at 1ghz and the phone can not enter deep sleep.

The only solution so far is to fully charge the phone and remove the battery for a couple of secs. And of course to charge the phone before battery drops 15%. It is a very common problem with chinese phones that have led notifications. And the problem is only with red led.

So if your battery drains really quick check cpu with spycpu.

That's why i'm asking if this is a problem with android version. I have 4.0.4.

I just got my Newman N2 Android 4.0.3 and it is also from China but it is Swedish. Should be some ROM with Swedish that works on my G2?

Regading the Swedish issue, I've also found this:

Dunno if it could help

Regarding the screen with lines, it's 90% an hardware issue. Luckily the Jiayu is really well built, so open it is extremely easy.

I would bet a buck that the screen flap went out.

Just open the phone and fix it

@ kokuo81: Thanks for the Android 4.1.1 ROM and guide how to flash it. Works fine here, without troubles so far! Keep up the good work!

As for language, it changed automatic on first boot to Dutch, probably because it recognised a SIM. So I'm very happy and also puzzled why Swedish wouldn't work.
[Android General] Gamlasakernyasaker:
I am also puzzled. I do not get the option to choose language when I boot for the first time. I do not think it would be no problem to get Swedish but I have tried everything except Supracer proposal but it is difficult for me :(

Which JB Roms are people using? I have one, not sure where it came from now (think it was on here (Says Build No G2H 20130118-115623)

I'm not in love with the battery life to be honest. Anyone on a different ROM with good battery life? (Compared to the stock ICS for example?)

Which is the best JB ROM out there? (for G2 dual 1GB)

From what I've gleaned LewOs are developing their ROMS but I dont think mine is a LEWA Rom and I need to find one I guess to make the upgrade path easier.

Hey guys,

I didn't find the proper cifs.ko modules for the 4.1.2 JB Jiayu version, but worked out something anyway :)

If you download the app File Explorer (https://play.google.com/store/apps/details?id=nextapp.fx&hl=ENG) and then activate the plugin for the network (it's a 7 days trial, but if you look for that app on google you can find a complete version "for free"), you can then create Samba network with your Windows PC.

Basically you can stream multimedia content from your computer to your phone, download files and open documents. Great right?

Hi Guys,

I just received my Jiayu G2L 512MB. I flashed the offical 4.1.2 firmware based on kokuo81's instructions and it went fine.

Now I would like to flash an english recovery (e.g. CWM) to the phone. Currently when I boot into recovery a chinese menu comes up, Unfortunately I can't use it as I don't understand chinese.

Does anyone have a recovery.img or any method to flash an english recovery to the Jiayu G2L 512MB?

So far I couldn't find one.

Thanks!

You must have flash installed.

[Android General] aliaird:
Hi, if you download CWM from here;

http://dl.dropbox.com/u/8463704/recovery_cwm5.5.0.4_ENG.img

stick the file on your SD card on your phone, then use the Recovery Update function of Mobileuncle Tools (from Google Play Store), you should be able to install CWM Recovery. Just to be clear, I have the 1GB version, but I'd be surprised if that made any difference here? (but I'm not an expert so don't blame me! :) )

Hope that helps. Sounds like you have Lewa 2.0 recovery at the moment. I've only seen Lewa 1.0 in English. It's a nice recovery but I'm happy using CWM to be honest!
[Android General] satmaster:
The only working recovery for me is LEWA v1.0 (thanks god :D) ... Device: G2H with original factory rom build 20120910-132127

CWM gives me a blank screen with backlight on and with TWRP the backlight is off and the screen is blank also...

This is crazy :laugh: :mad:

..but I performed a full backup with lewa and now I will wait for an official release of JB (if there will ever be...) :)

Thanks for your help! However I already solved it by getting the recovery.img from a firmware linked in this forum (update_25112012(black).rar) and flashed it with flashtool. Its also a CWM and seems to work.

I never heard of mobiluncle tool, so I'm glad you mentioned it. I'll check it and maybe it will be easier to flash recovery next time. Thanks mate!

Hello everyone,

I bought this phone [Jiayu G2 1GB RAM DUAL CORE] from jiayumobileshop.com

They sent it to me on 21/2 using hongkong mail and I received it on 4/3 (very very fast - considering that it usually takes items 30+ days to arrive to me from China).

The phone is outstanding for its price...I already upgraded it to 4.1.2 (using the 1st post on page 21 - very helpful).

Overall find it a little bit heavy - caused by the 2050mAh battery, the home button is not quality made and the camera is not so good.

But still for it's price - the phone is giving by far a lot gain/cost.

what about the GPS fix?

Updated:

Fixed using FasterGPS.
[Android General] kokuo81:
Hi, thank for the step-to-step guide appreciation :)

If I can ask, how much did you pay it?

For the GPS fix, you have to download from the Play Store FasterGPS (https://play.google.com/store/apps/...ult#?t=W251bGwsMSwxLDEsIm9yZy5mYXN0ZXJncHMiXQ..).

Grant it SuperUser privileges and then execute and set it according to your location.

After this, you have to install from the Play Store GPS Helper (https://play.google.com/store/apps/...EsIm5ldC5mYWJyaXppb2FsYmVydGkuZ3BzaGVscGVyIl0.).

It's not a free app, so if you want to buy it go for it, if not here you have a link with the app: (https://mega.co.nz/#!DAYDCDLR!XaqosVYAlxF1opyx5aWtPHKjo2Zu5JypPIDRO7D6iOo).

After you install it just go outside your house (:P) and wait the satellite fixing (you should have 6-7 satellites available).

Once they are fixed, you are done :)

P.S. I've ordered 2200mah original battery for the Jiayu G2. I should receive it this week or beginning of next week.

I'll post my impressions (I payed a really cheap price for it, 9,50$ shipping included) after a couple of charge/usage.

Cheers

kok
[Android General] saturn_frak:
Yeah, I fix it already as I updated in my post, Thanks.

I paid for it 160$, It came with the accessories pack.

I know that in the nearest future (in China) for the same money I could buy MT6589 based phone...

But still I'm very impressed with this one, worth every cent :victory:
[Android General] kokuo81:
Well, I was asking because here:

http://www.banggood.com/Wholesale-J...g-Dual-Card-Dual-Core-Smartphone-p-63538.html

you could buy the same phone for 146$ shipment included (using the referral promotion they have).

Anyway, great piece of HW :)
