Just google how to use at command to change imei. Its the best way to do so. MTK Engineering tool makes it more easy as with that app there is no need to use codes to acces radio information.
[JiaYu S3 Questions & Answers] motanbigcat:
I know well about this information and I've used successfully this solution with some other phones, there are too many ideas about imei changing of S3 in forums but just ideas, nobody says "Yes I tried this solution and succeed..", that's my problem.
[JiaYu S3 Questions & Answers] teamh:
My phone is Jiayu S3S rom 20150411. In mediatek engineering tool, AT Command tool got error message:"config file not found"
[JiaYu S3 Questions & Answers] :
Could be that there's a driver conflict left over from one of your previous installation attempts - in this case, use the utility 'USBDeview' to view and remove any drivers on your system that reference 'Mediatek', 'VCOM', 'MTK', 'Preloader' or basically anything to do with the Jiayu S3 phone.

USBDeview can be download from here.

Following this, reboot your machine and retry the installation sequence I previously outlined again from the beginning.
[JiaYu S3 Questions & Answers] adilrenzu:
as i have posted it already, it works but only if you have lost your IMEI, it will not work to replace your existing IMEI, to change your existing IMEI, you need a PC software.

P.S: if *#4364# wasn't working i wont have posted it. i Have tried it so many times.
[JiaYu S3 Questions & Answers] :
Silly question perhaps, why would you want to change valid existing IMEI ?

Agreed, if it is gone you want to recover it (some people claim to have done so), but why change existing one?

[JiaYu S3 Questions & Answers] adilrenzu:

mobile uncle doesnt work with JIayu s3 or for even any 6752 device.
[JiaYu S3 Questions & Answers] teamh:
He change imei to get the phone recognized as 4G phone by mobile provider, so he can take advantage of this. Free mobile in France for example, has 20Go of fair-use for 4G device.
[JiaYu S3 Questions & Answers] :
adilrenzu

My mistake. I had installed mobileuncle and just clicked into IMEI and see there is no support.

However, TWRP offers IMEI backup and restore
[JiaYu S3 Questions & Answers] TheCityAndTheStars:
It can be changed without any problems with this command.

I tried it on my Jiayu S3 advanced.

Replaced imei, ie used my old phone's imei and then returned original imei number of Jiayu.

As soon as i replaced imei i got automatic settings for the old phone model from my network.
[JiaYu S3 Questions & Answers] teamh:
I succeed change Imei of this phone.

1. Enter mediatek engineering tool: *#*#JIAYUS3#*#* (*#*#5429873#*#*)

2. Go in Connectivity -> CDS Information -> Radio Ìnormation -> choose phone 1 or phone 2

3. Type in first line AT+ EGMR=1,7,"your imei"

There is a space between AT+ and EGMR.

Do Send AT Command and then reboot the phone. You can check new imei by typing *#06#*

For phone 2 use AT+(space)EGMR=1,10,"your imei"

Lost imei

Hi there, after I managed to fix my both phones I lost the imeis for one of them. So I decide to put the Imei from the box manually but there is only one imei mentioned on it. So I put it on both simcards and it's working but sometimes (very often) actually the second sim is loosing signal. How can I get the original imeis for both sim cards? The other phone found them automatically and they are different.

Thanks

P. S. I am using rom s3sw 20150213-171816

Everything is working, 4G, Bth, nfc, etc
[JiaYu S3 Questions & Answers] motanbigcat:
Long story, I'll try to shorten, S3 has just a single imei number, but I need two different imei numbers for the legal proceedings which are needed in my country, otherwise I can't use the phone as double sim, if I try to use, one line will be closed within 15 days by official authorities. As you can appreciate I can't buy this phone if I can't change the imei number.
[JiaYu S3 Questions & Answers] cyberdejy:
I was wondering why the other phone recognized two different imei numbers automatically even that on the box is only one and it's totally different than the one in the system. So I thought that maybe I have to put two different imeis. But anyway if it's not a problem I can leave them as they are
[JiaYu S3 Questions & Answers] :
I tried to update slot 2 from xxxxxxxxxxxx19 to xxxxxxxxxxxx20 but it stays xxxxxxxxxxxx19.

I tried EGMR=1,10,"your imei" both with and without quotes "" around new imei xxxxxxxxxxxx20.

I do not have a SIM card in 2nd slot, would that matter though?
[JiaYu S3 Questions & Answers] teamh:
AT+ EGMR=1,10,"xxxxxxxxxxxx20"

Remember there is a space between AT+ and EGMR, with quotes" ", after send AT command you have to reboot the phone for the change to take effect. I have 2 sim when I test, so you should insert another sim to 2nd slot and try again.

Screenshots added, imei 2 changed to xxxx20 ;)
[JiaYu S3 Questions & Answers] :
[MENTION=6469559]teamh[/MENTION]: my bad! It -does- work :rolleyes: (previous attempts missed one digit in imei)

Hi.. is there someone whose switch the runtime from dalvik to ART? its safe or not? Isn't true it makes android more faster?
[JiaYu S3 Questions & Answers] :
I switched but I doubt if the dex files are art, for sure they are not ELF ARM shared objects as on another (lillipop) phone I have.
[JiaYu S3 Questions & Answers] :
It's a fake toggle I'm afraid. ART doesn't work on this phone yet, at least with the stock KK ROM. It'll be fine though come LP, as that version only uses the ART runtime.
[JiaYu S3 Questions & Answers] teamh:
you can tap About phone in Settings seven times to unlock Developer options, from there you can select runtime.

This phone doesn't has art libraries... When choosing under development options art Java VM and after reboot cpu-z still shows java VM as dalvik.

It only 'pretends' to work (dev option shows ART), but behind the scenes Dalvik is still used.

Anyone found/used a good kitchen for cooking deodexed system?

I tried ArchiKitchen but it says every apk/jar already has a classes.dex, which is true!.

like

INFO: EngineerMode.apk contains classes.dex already, removing EngineerMode.odex

Does that mean one can simply remove odex files and dalvik will create dex? I slightly fear and doubt it...

I am on Amaysim a reseller of OPTUS and I remember that the first time I booted network had a red cross against it.

I disabled and re-enabled carrier in settings and it came good. Hope that helps
[JiaYu S3 Questions & Answers] MarkGiardini:
Thanks mate. I've tried it several times with no luck. I'm sure its listing Vodafone 4G on its list on networks!
[JiaYu S3 Questions & Answers] :
Mark

You know phone sim is middle hole?

RH slot is data slot or second sim

How about a screen shot of your settings in sim management?

try touching the green slider to turn off then turn on again.

BTW are you in the country? 4G can be a bummer as per

http://whirlpool.net.au/wiki/mobile_phone_frequencies

so you may drop back to 3G or 2G

from your carrier FAQ

EDIT

install and run CPU-Z to check if you have been sold a fake pls

EDIT2

some of their sims have trouble as per their faq

http://www.vodafone.com.au/aboutvodafone/network/4g/faq

see section on do I need a new sim card
[JiaYu S3 Questions & Answers] MarkGiardini:
Hi mate.

Thanks for the reply.

Yes I've got SD in SD slot and the sim card in sim slot 1.

I get 4G when that same sim card is in my Huawei Mate 7 and LG3 and only 3G on the Jiayu.

I tried running a network test app and it comes up "fail" while searching for 4G on the Jiayu.

Sim card is a new nano sim so hasn't been cut down. And phone I'm sure is from legit Aussie seller (via Gumtree). I'll post you screen shots tomorrow! :thumbup:

are you sure about this?

AFAIK we have a micro sim

if not a typo you need to go to any good phone shop and buy the converter

or search ebay for = 3 in 1 Nano SIM to Micro Standard

cost a $1 at ebay but expect to pay $10 at shop

2) in case you did a typo here are my specs according to CPU-Z

Hi there. I am far from being an experienced user, but I think that you have a Saw rom and you shouldn't update with the 4/11. The last update you must have is 25/3. Don't take my word for it, just check it out. They are different roms and you could confuse your phone

hi mate, i've just had this phone for several days and this is really an amazing phone, especially the display.

I got the 3GB RAM with playstore, so it's S3SW ROM.

I just found out after reading the post here that there is echo bug happens to the person receiving call and slow charging bug, and to fix that we just need to update using OTA update, and there is notification in the wireless update section about 52mb update in chinese, so I dont really understand what did it say, so I wanna ask should I update it or just wait untill lollipop update out? did it really fix the bug or just adding another bug? I really enjoy the handheld for now and too scare to mess it up.

I'm sorry for asking so much, really newbie here and I really appreciate the help, thanks.
[JiaYu S3 Questions & Answers] agdroubi:
From what you are saying I can conclude that you have s3s ROM. So I advice you to switch to s3sw, better than applying the update and loosing google services. But you can make sure you have S3sw from about phone. If you are sure your phone is s3sw, then apply the update.
[JiaYu S3 Questions & Answers] :
There are some interesting comments to be found on the MTK GPS UTC 1h

mismatch, ranging

from

GPS sees sky and its sattelites one hour wrong

to

GPS uses GPS time upto nanosecond and could otherwise not possibly work

I have a Galaxy S4 and a Jiayu S3SW.

Galaxy S4 has correct UTC time, Jiayu S3SW has wrong UTC time.

Both lock reasonably fast (seconds, even inhouse).

I opened GPS Status Pro on both, S4 sees more sattelites than S3SW,

but, the ones seen by S3SW have the same number and location as seen

by S4.

I don't know anything about GPS techology, but, at first sight, I

would believe that the 1h mismatch is a cosmetic bug and has no

functional impact.

Perhaps someone else has a better way to examine 'sky of sattelites'

and also has a phone with and one without 1h mismatch to

compare. Please let us know. I would be happy to examine same way.

hello guys

I just ordered the jiayu s3 2gb version for around 170€ + case. I was thinking about either getting the s3 or the elephone p3000s and decided to go for the jiayu, I choose the 2gb ram version over the 3gb because I am not going to do a lot of multi tasking or gaming, so I thought 2gb are enough for me.

I have a question now though, I saw I will maybe need to add Google playstore manually, thats not a problem but I read here there are different roms, are there huge differences between them or just the w/ Gplaystore or w/o Gplaystore? and do you think lollipop will be released soon for the S3 or is it going to take some more months? I saw you guys discussed that already and I am sorry for asking again but I have read the last 5 sites and didnt find a fitting answer^^

I hope someone can answer my questions :),

weak signal

hey guys!

i have the S3 Advanced for a couple of weeks, it's a great device! build quality, camera, battery, display are quite good for the price, i am really happy with that :). but besides the pros there is one major flaw, at least in my case: the signal strength. in my area i get with my old nexus s a constant dBm of -87. with the jiayu s3, the signal is really fast hopping between -95 and -106 dBm with a lot of signal loss, so it takes quite some time till the data connection is established again. it is really annyoing when you are browsing the web and suddenly you are stuck because there is trouble with the data connection. is there anything i can do to get a better signal reception? maybe a new radio image or something like that?

best regards,

andi
[JiaYu S3 Questions & Answers] :
MarkGiardini

Its possible the seller has made a bad config or did not know how to fix?

2) in the meantime, I suggest you download "MTK engineering mode" by the monster

open it -> android settings -> Phone info

go down to

Set Preferred network type and select (if different)

LTE/GSM auto (PRL)

let us know if it was stuck on GSM/CDMA which would explain why you did not have 4G

see attachment

3) edit I have installed the same app= network strength signal strength and images attached

OOPS I forgot to mention that if you make a call.....it will DROP to 3G

4G is only for data

4) now lets look at your vodafone 4G network and go into the mtk engineering app but this time choose MTK settings

-> telephony -> Bandmode -> sim1......scroll down to LTE

for me I won't show an image I have ticked boxes....3,7,20, 38to41 inclusive

on my network I need a min of 1800 which is band 3

2600 b7

wish list is 700 for country but its b28 which is not active.
[JiaYu S3 Questions & Answers] MarkGiardini:
Hello mate - PM sent.

I did download and run MTK Engineering Mode apk, and ran it, and those parameters were there by default in the 'Network Settings' (LTE/GSM auto (PRL))

I believe possibly that the 4G bands covered by the Mediatek processor are not compatible with the 4G bands which Vodafone uses here in Australia, as I have a Huawei Mate 7, and I get perfect 4G on the Vodafone network, same same, same places, and just different phone.

Does that make sense?

I have a problem. Since I bought my S3 Advanced, I've been using a 3g sim in first slot, and another one on the second slot (of course, it could only connect to 2g). Today I changed the 3g sim with a 4g one. Now, no matter if I use the 3g or the 4g network on the first sim, the second one doesn't get signal at all.

What frequencies does Vodafone use?

4G/LTE – lets you surf the internet

Our lightning fast 4G data network runs on these frequencies:

1800MHz850MHz
[JiaYu S3 Questions & Answers] :
Ok so for the moment we have

850 = B5 which is not active on my phone

1800 = B3 which is active

now it also appears there is a slight difference in protocol as I am not an engineer here are links

http://en.wikipedia.org/wiki/List_of_LTE_networks

second link...forum thinks is not a link so here is txt in quote box

the is no preceding http:// to link

Note that 850 is FDD and 1800 is also FDD

as we share the same 1800 FDD......why not buy an amaysim sim just to check it?

Yes I know you have unlimited data on weekends but $45 gets you unlimited calls and txt and 5G of data

I won't provide a link as A) I am not a sales person and B its against the rules

If this sim fails for you........go back to my earlier request a couple of pages ago to check you have not been sold a fake by running CPU-Z pls

2) you are not under a concrete or metal root when doing tests by any chance

see if any different to outside

3) see if vodafone will give you a micro sim card ....they should be able to make it the same number
