[Upgrading, Modifying and Unlocking] grafeno:
Thanks for the story of your experience, which for me, is a bit late because I sent mine to China. It is curious that the shipment take longer since arriving in the country until they delivered to the recipient (10 days), that the journey from Spain to China (8 days). And I got delivery confirmation 2 days after they had delivered.

They say me they send to the factory for repair, it will take 15 days. Plus another two weeks until I get it, more than one month duration of the whole process, if I'm like you, staying two months in a Chinese shelf.

I hope it repaired properly or give me a new one that works as it should. I'm not shure if mine G2S has same problem like yours, because when I use Line voip calls, they can hear me perfect.

Anyway, I have to wait patiently, hoping that I do not do what you have had to suffer. I'll tell you how you repair the journey.

Sorry, but I didn't understand "Wipe dalvik and clear data"... I'm noob and my english is limited :o

I fix the noise problem for my listener (like a interference) "scraping" a little bit between contacts (positive and negative thread). In my case, the weld probably caused a dead-short (curto-circuito in brazilian portuguese) in the microphone, causing the interference.
[Upgrading, Modifying and Unlocking] kkenpachi:
i have the same problem with the microphone the listener hear an interference sound as metal clink or high voltage noise but not always. I have record sound files and have no problem with the sound i have also speak with others with voip and again no problem ofcourse with hands-free and bluetooth also no problem . The problem exist only when making gsm calls has anyone fix it???

augustouser which contacts have you scraped ?
[Upgrading, Modifying and Unlocking] augustouser:
I removed a bit of solder between the red and black wires... with the tip of the screwdriver. I put adhesive tape too, to help separate the poles.

It works! Actually, my G2S mic doesn't work well just on skype.
[Upgrading, Modifying and Unlocking] geronimoid:
Hi.

Please first try flashing the recovery.img from my previous post. That may be enough for you.

If unsuccessful, follow steps 2-7.

To answer your question, just look for the two lines in CWM with the words 'dalvik' and 'data'. Select and confirm for each :good:

Thanks for links collection for G2S, I have finally solved high battery consumpion on sisters G2S. I have first installed TWRP recovery, than reinstalled stock rom (this deleted all user data on phone, so you should make backup before), and finally I installed autobrightness and redlight fix. Battery consumption is much better now..
[Upgrading, Modifying and Unlocking] abaggie:
Nice:good:, I found this rom the best of all roms I tried. And I tried allot stock rom,lewa,miui some Russian custom roms. But after all I found the one I linked the best. You can try it if you want.
[Upgrading, Modifying and Unlocking] twrock:
Thanks, but the link won't work.
[Upgrading, Modifying and Unlocking] geronimoid:
Nice ROM, but for some reason can't enter GPS settings through mobileuncle. Anyone else got the same problem or know a workaround?
[Upgrading, Modifying and Unlocking] abaggie:
The link: http://www.needrom.com/mobile/jiayu-g2s-v-3-0/

I know it won't work because ygps/settings are configured in te gps.conf file. You can fix up in two ways: Set the gps.conf file for your country (stock its set in Spain) or install the ygps.apk (copy to /system/app and set permissions to rw-r-r).

But what worked for me is ignoring the settings in MTKtools and just set gps.conf to my region/country (with fastergps) and then going to Settings>Locationsacces> (turn on GPS) hold GPS to enter advance menu and thick A-GPS and EPO (and download new epo). And then test it with GPStest outside worked fine for me.

(if that doesn't work go to root -> data -> misc and in misc delete mtkgps.dat (and gps.conf if its there) Reboot and then try the above.
[Upgrading, Modifying and Unlocking] geronimoid:
Hi and thanks :good:

In the end i just couldn't get mobileuncle to enter the ygps settings no matter what i did with the apk (even tried flashing the rom with it included), so i'm using your fastergps suggestion which works fine :)

The only thing I'm concerned about is the lack of NMEA logging. I'm wondering whether this will affect the gps fix time in any way i.e. will it 'cold start' if i have no agps data AND no logs? There are a few guides on configuring the MTK gps that suggest it's initially necessary to collect NMEA logs to speed up the fix, though logic tells me a hot/warm start would probably be using the mtkgps.dat file :confused:

By the way, to answer your earlier question about the jump screen fix recovery.img, it's based on CWM 5.x. I have no idea why this fixes the issue, but it seems to have done the trick for a few of us :)

Cheers
[Upgrading, Modifying and Unlocking] davidgascon:
Hi. I'm the modded who made this rom. Only two things:

1. This rom was made for spain so there are any apps that only have english and spanish languages.

2. To change the first boot language/country you must edit the build.prop and change:

ro.product.locale.language=es

ro.product.locale.region=ES

to set your country/language and change:

persist.sys.timezone=Europe/Madrid

to set your time zone
[Upgrading, Modifying and Unlocking] abaggie:
Thanks for this and your ROM:good:

Maybe its an idea to make an non Spanish based ROM something like v3.0 international. Some suggestions would be:

- Set default language to English.

- Add some other (stock android) languages.

- Remove Spanish apps/settings.

- Re-enable Location (based Service) - YGPS.

- Add Google keyboard because it supports allot of languages.

Other then that I think the ROM is pretty good as I said it's the best/fastest and most stable one I used so far.
[Upgrading, Modifying and Unlocking] treborblack:
Having read an earlier post about using external gps devices, I proceeded to obtain a free globalsat bt359 and purchased a holux m1200.Both devices would work for up to 30 minutes before losing gps. It occurs to me there is a problem in the Bluetooth stack.

Moving on I opened up the phone and removed the crap gps antenna and replaced it with a postage stamp sized piece of aluminium crafted from a takeaway tray. Remember it only has to touch the top terminal otherwise it'll short circuit the gps chip. Signal strength and keeping lock were so much better than before.

Anyways I'm now the happy owner of an xperia sp my eyes (over 40) needed a better screen, and with both gps and glonass it locks within seconds.

Just don't give up on the Jiayu. True the assembly is questionable but for the money and twenty minutes work I don't think you can beat it.
[Upgrading, Modifying and Unlocking] geronimoid:
Hola David,

Your ROM is very nice indeed so thank you for your good work - I am using it now :)

I especially like the new clock and contacts widgets :good:

I agree with all of abaggie's points above, especially about the YGPS and the stock keyboard (with languages). If you could include these you would make the best G2S custom ROM around...

Finally, there was a lenovo port over at needrom with an excellent camera,,, any chance of including it?

Looking forward to 4.0!

Many thanks again :good:
[Upgrading, Modifying and Unlocking] twrock:
This idea is new to me. I don't remember it being mentioned before. (Sorry if it has been.) Where did you learn about this idea?

So if the main problem is that the current copper antenna is short-circuiting the gps chip, what about the idea of simply putting in a thin piece of plastic so the bottom terminal is not connected? Or maybe one could just bend the bottom antenna tab away from the terminal so it won't touch? This seems much simpler than replacing the antenna.

I'm guessing that if it is a short-circuit problem, the current antenna is probably not a bad shape and size to use. If so, why replace it? Maybe just disconnect it from the lower terminal and see if the results are the same.

I'm still cautious because doing any of that will void the remaining warranty. But maybe I will just give up on Jiayu and take my chances with fixing it myself. But I'd like to know as much as possible before I make that decision.
[Upgrading, Modifying and Unlocking] treborblack:
I got the idea from watching this video for the icoean x7,

www.youtube.com/embed/2q_AmYlrwNc

It seems a lot of mtk based phones have problems irrespective of chipset 6577T on the Jiayu g2s or 6589 on the quad cores.

It worked for me is all I can say.

In Hindsight I was brash in tossing the original antenna, as you suggested It may be worth insulating the bottom terminal with electrical tape to see if it works for you. I can't see a reason why it would not. If not then search some more on home made atennas. I needed to get gps working as I was selling the phone and needed to maximize my return.

Good luck

Hi,

I am in the same situation. Need to get the G2S work in the 850Mhz band. Did you manage toflash the baseband?

[Upgrading, Modifying and Unlocking] 1_Petje:
Hi, Did you find a digitizer + LCD display? Mine is also broken, and I'm trying to fix it. When I look at pictures of the digitizers that webstores like Aliexpress offer, a question raises about the screen gasket.

I wonder if there is also a replacement gasket (adhesive) underneath the glass top layer, for mounting it on the aluminum body frame? can you confirm there is a gasket?

please let met know.
[Upgrading, Modifying and Unlocking] jobrima:
Yo must buy in:

http://www.jiayumobileshop.com/jiay...-cell-phone-lcd-display-and-touch-screen.html

You must paste the screen to the frame with double sided tape.

Don't forget speaker cover pasted in broken screen!

[Upgrading, Modifying and Unlocking] geronimoid:
Also you may find that using a hairdryer to separate the old screen from the tape, you can heat the tape a second time before applying the new screen and it will stick :good:

[Upgrading, Modifying and Unlocking] 1_Petje:
Hey thanks! What shipment costs do they charge? or is it also free, like almost all china web stores..

I wonder what's the original adhesive that jiayu uses.

It's some sort of foam-double-sided tape, with a thickness of about 0,3mm? I guess the foam structure of the adhesive is for handling shocks and vibrations (my phone previous did survive a 3feet fall on a tiled floor!!)

some one here with experience in replacing touch screens, I've been looking at some apple-device tutorials. but have not seen any web link to a suitable type of double sided tape.
[Upgrading, Modifying and Unlocking] jobrima:

[Upgrading, Modifying and Unlocking] geronimoid:
Register on the site first and save yourself $5

No need to buy double sided tape. Use a hairdryer to remove the old screen and try to keep as much of the old tape on the phone as possible. It will still have adhesive if you remove it slowly and you can add a few small dabs of superglue for peace of mind :good:
[Upgrading, Modifying and Unlocking] 1_Petje:
Cool, thanks guys. I think geronimoid's tip is the best. using a hairdryer and some drops of superglue. If only I wasn't that eager to disassemble my phone's screen directly after I cracked it :(

So my adhesive is totally screwed up. I ordered the screen at mobile-phones.cn Should come in in about four weeks. pff that's a long time doing my old nokia.

Ill let you know when I'm going to remount.

I find a soluce for interferences

Hi, I'm from France, sorry for my english! and thank you for this international forum about Jiayu G2s!

I had exactly the same problem, low sound and big interferences for the listener, exactly like when you put a phone near an FM radio.

The phone returned to Jiayu China via the HongKongGeek aftersale and returned to me after 2 months!!!!!:crying: The sound was more important but always interferences when you are not near a GSM antenna and when the phone is sending datas(they probably just return the mic, issue of a bad factory mounting, see on an other forum).

I contacted HKGEEK again, impossible to send another time the phone, they explained to me that they tested the phone and all was ok... so stupid people... so bad shop!

THAT'S WHY i decided to open the phone after see this post and to make a metal shield near the mic.

The microphone is just near the gsm antenna (sticked on the plastic like the GPS antenna, near the usb socket), and i don't found any metal shield between antenna and mic on my phone... :confused:

Take a piece of a good tape (like duck tape), a piece of kitchen aluminium and put a piece of tape on the mic contacts and wires(for dont make a short circuit) and after a piece of alu on this and let it touch the mainboard juste under the speaker (it's the mainboard "ground", look the photo), don't touch the speakers contacts! after put 2 pieces of tape on the alu, the speaker will press on this sandwich when you'll close the phone for a good contact.

AND NOW!!: extra sound quality and no interferencies!!! (Thank you MacGyver!! remember;))

Hi there, one more thing in case of sollution for jumping screen - post 331:

tanks for sollution, but it seems, that attached file opens cwm menu in Madarinian,

can you please write some quick, maby small tuto, which options choose to run this file?

This G2S belongs to my wife and I don't want to brick it. She would brick me if did the same to her phone.. ;)))

jumping screen is really annoying, I don't know if you had the same issues, but my for example, opens randomly links in browser while browsing pages, menu buttons, conacts, messages etc.
[Upgrading, Modifying and Unlocking] geronimoid:
You don't need to do anything from inside CWM for the fix to work. Just flash the recovery.img and you should be 'jump' free :good:

The problem you mention in your last line sounds like it might be a separate issue. You might think about reflashing the ROM if it persists after flashing the recovery, making sure not to touch screen on first boot.

Please let us know how you get on...
[Upgrading, Modifying and Unlocking] 6grudnia:
yes, I'm a noob...

start the recovery from mtktools, when it provides me to cwm menu (with chineese signs) - rebot the device and thats all?
[Upgrading, Modifying and Unlocking] geronimoid:
Yep, inside CWM just select the first option - or if the Mandarinian really freaks you out you can even pull the battery and just boot normally.

Any improvement?
[Upgrading, Modifying and Unlocking] 6grudnia:
not any change, so as you mentioned, it might be a different problem

the software version is 2013.03.06-143807, so it should be updated with the screen bug fix, but as I wrote before - screen jumps when I hold it for a while, it acts like it was hypersensitive, but in deeper look - phone runs applets, windows, browser links, contact details etc. - itself.

I have some vids (around 3-4 Mb) if someone is interested.

Flashing the ROM is too much for me, so I wait what the Chineese seller writes for my demand of guarantee change device or give it back.

Anyway, thanks for your responses and help, I appreciate that.

cheers!
[Upgrading, Modifying and Unlocking] 6grudnia:
Well, a little annoyed with jumping and self living screen, I've decided to flash the rom. In first minutes - looks like it started to work normal, for next few hours I'll be testing the device. I used latest rom, dated on 06.03.2013, just uploadet it agai, because it was the same one previous.

I used a tip with "don't touch the screen at first bot" - maby it was also an issue...? No matter. Let's start testing :)

big thanks and respect to twrock for the instruction of flashing the rom, at the beggining of the thread.

geronimoid, thanks again for tips :)

Netflix on Jiayu G2S?

Hi,

Mine is running this 2013.03.06-143807 version, and Netflix does not work. Browse and select videos does work, but videos do not play.

Does this happens for other G2S users too? Is it a problem in the ROM? Is there any workaround? I've tried the latest official Netflix build, and also some alternate versions found here (xda-developers.com). None of them can stream from Netflix.

Thanks!
[Upgrading, Modifying and Unlocking] 6grudnia:
I don't know about Netfilx, because before I started playing with videos, it occurred, that casual apps - contacts, sms, email, browser - doesn't work properly. When opening an app, phone randomly starts buttons/options inside. Like opening a site in browser, and the phone starts automatically links on the site and goes from one site to another by links on each site.

After flashing a rom - test showed, that changing software didn't help. Phone went back to China today. We'll see what will Chinese seller offer - change, or money back. After all - my wife liked the phone, so we'd be happy with the new one, working good G2S. Are there any?

[Upgrading, Modifying and Unlocking] twrock:
It is quite similar to flashing the complete rom. Make sure you understand the second post completely first. If you know what you are doing with that, then you can proceed to do the following.

You copy the modified recovery.img into the folder with the other rom files (replacing the recovery.img that is there).

You start the SP Flash Tool. You choose the scatter file. You uncheck everything but the RECOVERY file. You click on "Download" (not on "Firmware -> Upgrade" this time). You will see a "Download warning", but click on Yes anyway. Plug in your device as with the previous instructions on how to flash your rom update.

Good luck.

[Upgrading, Modifying and Unlocking] EAPOCS:
4 main questions regarding this phone.

-The newer rom (20130108) that comes with the device, without flashing it on your own, is it the 2nd batch so that the Jumping Screen is not a problem anymore?

-Someone mentioned the problem with the GPS, that is far from accurate , 50m off:eek:, can someone confirm this?

-How is the camera? I know it won't be great, but are there any bugs or problems with recording or whatever?

(Does it support 720p videorecording @25/30fps ? G3 doesn't do that atleast i don't know)

-Any other further grave bugs that can't and probably won't be fixed?

Thanks

Otherwise this looks like a Bang for the buck, it looks more solid than the G3, where i have seen youtubevids in which it was stated that the the body housing cracked numerous times:eek:
