I found the solution on a polish websites.
You have to use unlockroot application.

I'm looking for a new ROM maybe new Android version for this phone?
At the beginning I tried to root the phone with the Zhoudashi but it didn't work but now I have a problem with the phonebook.
When I have an incoming call the name is not match from the phonebook - I see only the phone number
As the name of SIM1 and SIM2 I have the china letters and even the hard reset does not solve these problems. Of corse I can change the name for the SIM card but I think my ROM has been modified by zhoudashi application.
What can I do to fix it?

Easy Way!

@Hani85
I'll keep looking for ya..
As for the best rom... I have no idea.. I will say this though. If you have the international model of the s2..Do Not Flash Any Roms from the epic 4g touch forum.. you will end up with a soft brick or worse a new shiny coaster.. If you get our bootloader stuck on that device.. chances are Odin nor anything else will recognize it and you will be stuck hoping a jtag can save ya...
There is a forum for that specific device..
EDIT.... I'm a retard... I see what you're asking now.. lol. I'm not sure as I'm a boost Customer but I would imagine that the tw based roms would be the better choice..

That's a CM rom(cyanogenmod) not touchwiz based... a good tw based rom I use is projectx 3.1 ... there is a new version of it, but I haven't flashed it as I've been on vacation and been playing around with a rom I ported for my gtab 10.1...
Jellyverse is a good one...
Really all of them are good roms.. just depends on you're style.. lol..
Also... I think that rom you linked is not for this device.. I didn't look, but it says for exhilarate..

Have you tried redownloading? Sounds like a bad download. Make sure you verify the file integrity via md5sum.

Yes, flashed maybe 2-3 different ROMs nothing helps.
I've lost EFS folder. Trying to find out different methods to restore EFS folder/informations from dev/ partition. :crying:

Not ROMs, you need to reflash the Odin One Click, ROM flashes don't touch this folder

Is this one going to work in my situation http://www.rwilco12.com/downloads.php?dir=Files/Devices/Samsung%20Galaxy%20S2%20%28Sprint%29%20%28SPH-D710%29/Stock%20ROMs/JB/FL16/No%20Data%20Restore/Rooted

Yes but I recommend using GB27 for Sprint, GB28 for Virgin Mobile, or GC01 for Boost

The only way you'll be able to get those items back is to get the NV folder unlocked and salvaged from another sprint s3. Get one with a cracked screen missing back but USB and touch still working. After that you basically salvage the info from it and junk it after. Its illegal for two phones to have the same info active/receiving signal at the same time. To unlock the NV folder you'll need QPST. ither buy it 3.5 for 100$ or look around for for 2.7.402 or 2.7.384 or 2.7.374
I forgot which one detects the S2 and allows the edits. The open sesame door method works on it as well I believe. I did one not to long ago but my memory isn't fresh on it. Or you can use the android terminal method that is used on the prevail in order to get the files. Google is your friend for the "QPST" and for the "open sesame door method" and for the "android terminal backup NV items on prevail".

Samsung Galaxy S4 MT6572 GT-I9500 no service solution !!!

hello ! after a week of testing ive finally found a solution for samsung galaxy s4 clone ( mt6572 gt-i9500 ). with no service !
Soo , you have no service and can't make calls ! follow this instructions and you will be talking on your phone in no time
Its very simple : ( i'll add the necessary links / software for this job )
1. you need SP_Flash_Tool_exe_v3.1316.0.150
2. you need the WORKING ROM ! modified by me
3. you need MtkDroidTools
( this version is allready modified to work with mt6572 )
The procedure :
we must first format the phone using SP_Flash_Tool_exe_v3.1316.0.150 . soo we open the program and select the scatter file.txt atached in the rom . hit format and then hit OK.
Now remove the battery and connect the usb cable to the phone. it will start formatting the phone. wait till is ready ( you will see a green circle )
At this point , the phone is ready to receive the new ROM
you have allready selected the scatter file early'r .
THIS STEP IS VERY IMPORTANT !!! uncheck the CACHE and USRDATA at the bottom.
Now hit Download button , you will get a warning message, just press YES
Now put the baterry back into the phone, and connect the usb cable. wait till the process end's and when you see the green circle you can disconect the phone, remove the battery, insert back the battery and power on the phone , and voila !! your phone have working network !!
Next step is to write the IMEI...
Use MtkDroidTools ( you must have debugging mode on in the phone ) connect the phone to the usb cable, wait till MtkDroidTools see your phone , and then hit the big imei button. There you must provide the imei number ( you can find it under the battery ) after that you hit write imei and then reset your phone and you are good to go
I presume that you allready have the usb drivers ( if not, i can also provide them )
For other questions use the forum below
If i have saved your day, maybe you consider making a small donation ( for that, use the DONATE TO ME button under my name )
Have a nice day !

Thanks for this tut, @pacattosul its very easy to follow, unlike some I've come accross, could I ask this?, will this not work by just using Mtkdroid tools as in the latter part of your tutorial? without the need of flashing a new rom?
Also I hope you dont mind a bit of constructive criticism, the developer of Mtkdroid tools @rua1 has specifically asked that his program is not placed on other sites for download, perhaps you could just change your post to link to his thread, here..... http://forum.xda-developers.com/showthread.php?t=2160490 Plus I do feel you are rather inviting problems by not specifying the details and build of your device that you have tested this method on, I don't have this phone but I'm sure there are quite a few different versions out there and the result of flashing the wrong preloader for your device can be a $200 paperweight, as I'm sure you know, and with that in mind I would stress that before embarking on this, a full backup is desirable in case it all goes t*ts up. Hope you don't mind my mentioning this stuff, if you decide to make those few minor changes, I'll edit and delete this paragraph, don't want to spoil your thread.

hello oscarblue48 !
i really don't mind that you point my mistakes... im actually happy cause as you say, MTKtools its somebody's work and should really be apreciated. BUT, this tutorial only work's with this special version of MTKtools !! i'm not responsable if you use any other tools/versions !!
you say that people may broke 200$ phone if they flash this rom... ok it may happend, but only if they mistake the model-version of the phone ! like ive say'd this tutorial and the rom only goes for MT6572 GT-I9500 SAMSUNG GALAXY S4 CLONE !! if they flash this rom on other devices they are responsible for what they do...
Actually , this rom goes for dead phones as well ( as i mentioned on other site ) , so i supose that most of the people , when they reach this tutorial, its for a good known reason
You also ask me if you can only use the mtktools... well you can easylly use that program, but you will probably not change anything inside that phone. most of the people try'd mtktool and complain that the imei remains null or empty after writing with this tool... soo in order to fix the annoyng NO SERVICE problem, i recommend that you follow the entire tutorial
I hope ive answered all your questions, and offcourse if you encounter any problem you can allways comeback and simply ask

Hi bro help me out here is my thread : http://forum.xda-developers.com/showthread.php?p=50483872
I tried your rom but still not working i can enter to recovery mode with different preloader and doesn't show me black screen when turned on as my big problem is i can not format my nand as you will see in my thread i was messing up with boot logo via root as it was rooted with supersu...so any help please as i have tried alot roms and i can't find stock rom for this phone MTK6572_S00 samsung s4 this is made in korea by samsung...and I do not have backup of my rom...
Thanks in advance

Please help

Appreciate any help
Update:
I have flashed it successfully - Also the IMEI, but still not registering to network.

be aware !! you have the dual sim ( 2 sim ) phone or single sim?? this only works for single sim phone... also, you must not try to flash this on dual sim phone !!
try this... go to settings and at the network tab change the connection mode... chose hspda preffered... that may do the trick !

[Q] No 4G/LTE capability after IMEI repair

My G3 was reported as stolen (presumably by the seller) shortly after I bought it, so the IMEI was blocked on my network. I sent the phone to the US for repair and, after some hassle and a complaint to Paypal, I received it it by return post almost 6 weeks later. Not sure if I can mention the "repair" company here but PM me for details, if you'd like them.
The phone now works on Edge / 3G but will not connect to any Australian 4G network. I've tried flashing the European (4.4.2) tot and Australian 5.0 tot but the situation persists. In slight desperation, I'll try the Hong Kong tot later today but in the meantime, does anyone know of a solution?
Possibly useful info:
There is no EFS backup.
The (new) IMEI is displayed in Phone Information and with the "06" code entered in the phone.
The model number is D855 (not D855K or any other variant)
The phone was rooted and running (I think) ANHD Lollipop when it was sent in for repair.*
Extensive searching has not produced anything that has been of use.
LTE is available in Network Selection and it sticks after reboot, so no need to use 'hidden menu', delete system files, etc...
* Probably the cause. The only instructions given were to send the phone without SIM or external SD card.

Have you tried this: http://forum.xda-developers.com/showpost.php?p=54621213&postcount=26
Or this?

Yes. It's nothing to do with settings, I think. I have LTE in settings, no problem. It just won't connect to any band n the hidden menu (I tried each one). Seems that the Australian LTE bands have been knocked out, somehow.
Just discovered that the phone will not connect to data network if GSM only is selected but GSM/WCDMA will switch between EDGE/3G (H - no H+)
HK .tot file did not resolve the problem.

You are wellcome, this is the way it should be i think. I'm old enough who knows sharing is a must ..
http://www.androidbrick.com/qualcomm-snapdragon-imei-tamiri-ders-4-qualcomm-snapdragon-imei-repair/ , the trick is to "zero" necessary partitions, and put your original imei in an orginal untouched qcn backup of your version. You can see it in the pictures of this article. Your 3 partition that holds this info are 21, 22 and 24.
