Not heard of this device. Perhaps a chinese copy of HD2.
OK, found something. It runs on Android, so you can only run Android apps. BTW what exactly you mean when you say things needed?

Need to se is it last SW, and need GPS for this phone.CoPilot Live- not work on this device !!

It runs 2.2 (as mentioned on the web), I don't have any idea if it can be upgraded, as you may know 2.2 isn't the latest version.
For GPS, you can check its specs if it has GPS or not, if yes then you can install the apps from the market otherwise perhaps connect an external GPS, although I am not sure weather an external will work or not.
You can click on 'Thanks' button, if I helped.

Model number : T8585
Android version: 2.3.4
Based Version : MAUI.11AMD.W11.19.SP.V1,2011/6/23 00:50
Need "working" GPS !!!!!!!

Maybe it could help us to help you if you could post the link.
The chinese website where I saw this, mentioned Android 2.2.

Many app not work on this mobile !

Maybe this will help : - h**p://www.efox-shop.com/hd9-mtk6573-4-3-zoll-kapazitiver-touchscreen-handy-wlan-umts-android-2-2-gps-dual-kamera-dual-sim-bluetooth-p-236121

since it is running android, so the compatible android apps should run on it, but since its a Chinese clone, no guarantees.
You can trying looking at other android phones by HTC or some other brand, to be safe.

You can try this rom Update_HD2_3G.zip www.multiupload.com/XOVS2HZTHO to remove all chinese aplications and to improve everything.

For fix GPS:
Enter *#*#3646633#*#*
Go to YGPS
Wait for the green satellites appear.
Go to NMEA Log
Click "save" wait 5 minutes and then click "stop". Repeat the process after 1 hour.

Is your cellphone the same of this?

I bought 1 of them.

Now HTC mobile phone is also very popular in China. But i am sorry i don't have it. It is a little expensive.

Is it upgradable to ICS???

[Q] Korean Version SHV-370K - ROM/GroupPlay/ChatON

Hey people,
I recently purchased a Korean variant of the S4 Mini. The model is SHV-370K. To my findings, its equal to the main version I9195. Is that correct? I do have the NFC chip installed. My question is, can I flash an official ROM like the ones used in the I9195? I have to much KOREAN language apps and I dont think I am prepared to root it. If I can flash an official ROM on this via ODIN?, will I still be able to get the OTA? My current version is 4.2.2. And checking on Sammobile I have the latest. The Korean stuff is just to much of a hassel and I am not sure if I will even get an update. Can I flash an official ROM and not lose warranty and root?
My second question is that I cannot make Group Play work on 2 of these S4 Mini's. They just dont connect. It says Network Lost and sometimes failed to join group. I've tried working it over with NFC and Wifi Direct. Normal gallery pictures and everything send easy, just this app that I really really want to use. Would be great if some one would help me.
My last question is that ChatON keeps giving an Error while checking for push services. I have tried everything. Changed networks, tried Mobile Networks. All my apps are up to date, even the annoying Samsung Push Service. Any help would be greatly appreciated.
Thank you so much people.
Have a great day.
Oh and I think its Carrier Branded? Cuz it has this Olleh writen on its back cover?

So ChatON and Group Play is working after they have been updated most recently. I did update them before but they dint seem to work. The current updates work good. Any one about the ROM issue? Would love some help <3.

you can only use a korean K rom, or a modify rom for the K version, otherwise you can brick your phone.

Hi guys,
Have you found any solution to this problem? I'm also an [almost] happy owner of a Korean-branded S4 Mini and as USSD codes don't work, was told that firmware needs to be changed. But this being specifically a Korean phone, I'm not sure other ROMs out there will even be 100% compatible.
Thanks,
Vit

Thanks, but I don't think I have to enter a password, since other phones work without it. Unless it's somehow phone-specific, but my operator reps would probably have told me (instead they just said the firmware needs to be changed). What secret menu are we talking about? perhaps aI could investigate. At any rate, if there someone has managed to flash the Korean version of the phone with a more "universal" firmware, I'd like to know. Thanks!

This secret menu allows you to modify the network, frequencies and other stuff, each korean service privider has it's own password.

you don't need the menu for the ussd, korean version has their own set of ussd, they are different from the international version, some are the same , but most are different.

Please forgive me as I'm a total noob, but after your last reply it hit me: we're probably talking about different USSDs. I meant that my operator USSD codes didn't work, the ones that I send to find out my remaining balance and to also enable/disable services etc. (e.g. I would send *444#2#1 to find out my remaining balance), not the phone's own USSD codes (like the service menus etc, e.g. the IMEI check with *#06#). Operator USSD codes just don't work - the phone either sits trying to connect for a few minutes (locking the phone down during this time), or just says that the signal is too weak. So I guess I do need to install a different firmware to fully unlock it.
Thanks for trying to help though, I'm learning new stuff!

Mate I have the same problem here. The USSD codes just dont work. My balance check does work though. All I have noticed that USSDS that need two steps dont work. Example to transfer credits, I type *456# and in return it should ask me what number I need to transfer my credits, but it just doesnt work. I have tried the menu but no idea what that is all about. Still cannot find what to do.
Secondly I met some one at the forums who has the same device as ours. HE said installing Cynogen Mod is working and it doesnt effect us having a model of SHV something. LOL. So I dont know if I should go ahead and flash a custom rom. I would rather flash an official rom but no one is helping here and I cant seem to find any. Like maybe we could flash an english rom from UK. Something official like the normal I9195 have! Not some korean ones.

New Update.
Hey people! I just got an OTA update and all I see new is a Google Drive icon. The update is still on 4.2.2 and not 4.3. It was about 96mb of file size. How can I take out the changelog and read what bug fixes it brings?

hello
how to do I move from SHV or change the CSC code?
for now getting only the Korean pop up messages.
Want to change to Australia CSC code.

I've read about CSC Select app (on google play market), but I think you need root for this to work. I'm not an expert on that though.

M8: Breaking of data connection

Hi again guys,
here in Croatia we have a problem with HTC ONE M8 (and M8 dual sim) and one network provider. Data connection is breaking non-stop (every few mins).
For M8, this issue was fixed with software update (users said).
For M8 Dual-SIM - no new software yet, I have 4.4.2.. Is there a other solution to fix it. Any experienced from other networks/countries?
Thanks

Well if it is this;
http://forum.xda-developers.com/showpost.php?p=55216767&postcount=28
there hasn't been a fix yet, and HTC Turkey at leats, is not aware of the problem.
But it is not every few minutes on every location, so you might be referring to something else.

Sounds similar... in Croatia it is fixed with latest fw upgrade for M8. Still waiting for M8 dual-SIM upgrade

What is the latest official fw for M8 (single SIM)?

interesting..
I'm on 3.28.401.6. That is the latest at least as far as I know, which brougt the "Eye" functions. Any other upgrades in Croatia?

I will check with users of normal M8.. I have dual-SIM so I cannot check. I am on 4.4.2

If you are rooted there is simple FIX, simple disable FD8 (Fast dormacy 8)
ro.ril.enable.r8fd=1
ro.ril.enable.pre_r8fd=1
Change both to =0 and issue will be fixed.
If your not rooted only fix is to keep HotSpot enabled than data connection wont break.

Thanks Ivica... I am not rooted

Other carriers
I too am from Turkey, have a One M8 and a Turkcell user and having these 3g data drop issues. While I do know rooting comes with many perks I don't really want to go through the hassle and risk bricking my brand new phone. I tried the Hotspot Shield trick but unfortunately that was in vain as well. So, any other updates on this topic? I also want to point out that afaik all sufferers who submitted posts here are Turkcell users. Does anyone know any other carrier customer who owns an M8? Are they having the same issues too?

There isnt such RUU or ever was, and if you dont have this options in build prop, try actualy adding them and set them to 0, but problems your having are probable because your using that base, it was fixed in one OTA, and it required RIL lib to fix data issue, your base doenst have this fix.Any other INT rom must work ok

Many thanks, I will go with the EU RUU found here on the forum. It is a different radio version also but I am s off and superCid, so should be no problems?

Please confirm if it is safe for me to do this. Thank you
Edit: just can not properly download this RUU. I will try with some other RUU's since I am S-OFF and SuperCid. Any recomendations?

Hi @ivicask
I'm using rooted One M8 Android 5. I changed build.prop file as you said with root explorer as r/w mode successfully but when I reboot my phone then when I check the build.prop file, it is unchanged. Build.prop file is always back to older version. How can I solve this issue?
Also I tried several times with ES file manager, root browser, buildprop editor but it always turn back to older version after the reboot.
Thanks a lot.

ITS HTC write protection, you can flash kernel/or WP kernel module to enable it, or S OFF device to gain full acces to device nand.
Its mostly integrated in any custom rom.

Downgrading from Android 10 to 9 locked bl

I am stuck at the latest version of android 10 (.618) on my xperia xz2 compact H8314 and I have a big problem using whatsapp and other messaging apps like messenger and telegram, basically the voice notes sounds very low, I can record audio using sony audio recorder and works fine but the other apps dont, I have been looking for this thread all over the xz2 forum but could not find it so thats why I decided to create it, I have also looked in other webpages but it seems that are very few mentions of it, I found this one and tried to follow it, but I failed in my attempt.
https:// xperiafirmware. com/downgrade/
Any help/advise is welcome and even questions of what I have already tried.
I thought about any other alternatives like fixing the problem in Android 10 but I couldnt either.
Edit: I get the next error message when I am flashing the .ftf file that I downloaded there:
"Those data are not in the FSC scrip and will be skipped:
BOOT,DSP,FSG,MODEMST1,MODEMST2,RDIMAGE.
Do you want to continue?"
then I try to turn on my phone and get the message "your phone is corrupt and it wont start" or something like that.
I have owned several xperia phones in the past, the last one was xperia X compact and I remember (I could be wrong) that I was able to make a downgrade without unlocking my bootloader.

I succesfully downgraded from 10 to 9 using sonys flashtool with bootloader unlocked. But I'm not sure if it's possible to do it without unlocking at the moment. Why not just unlock the bootloader?

Would be helpful if:
Where to get the Sony flashtool. (link?)
You could provide a link to how to unlock the bootloader. and
You could describe the "Downside" to unlocking the bootloader. What "no longer works"? Such as, will it no longer apply factory updates? Will Digital Rights Management (DRM) no longer work?
Seriously, my XZ2 Compact H8214 keeps reminding me (several times a day) that a firmware update is available, and I am sort of "scared to death" to do it. All I read are negative comments about what Android 10 has done to ruin people's phone. Without a way to "go back", I am seriously thinking of just ignoring these messages for weeks and weeks.

Well first of all, unlocking bootloader voids warranty, then a number of several sony technologies will for sure stop working, Basically all proprietary technologies like audio, video and most importan thing, CAMERA enhancements, how I do know this? well because I have been reading a lot lately and also since some years ago, and by experience because back in the day I had an xperia x compact and I didnt remember to backup DRM keys before unlocking bootloader.
Anyway I have found a way to downgrade from android 10 to 9 without unlocking the bootloader, I am not sure about if I should make a new post with specific instructions( a guide) or just write them in this post.

Oh, yes. Please share. The more details the better. (Assuming that people "know basic things" is often incorrect. The things I don't know is FAR too big to list.)

Well first of all, unlocking bootloader voids warranty, then a number of several sony technologies will for sure stop working, Basically all proprietary technologies like audio, video and most importan thing, CAMERA enhancements, how I do know this? well because I have been reading a lot lately and also since some years ago, and by experience because back in the day I had an xperia x compact and I didnt remember to backup DRM keys before unlocking bootloader.
Anyway I have found a way to downgrade from android 10 to 9 without unlocking the bootloader, I am not sure about if I should make a new post with specific instructions( a guide) or just write them in this post.

I have downgraded from 10 to 9 using official flashtool from sony (with bootloader unlocked) and my camera, audio, video etc. still works just fine. Maybe I just got lucky, but I think that by doing it through the tool provided by sony itself it shouldn't break anything. Which in my case, it didn't. Btw, thanks for the guide ?

Or maybe you don't know what you do, and happy for the nothing.
If you unlock the bootloader, you loose the TA partition (DRM keys). Your camera quality is worst, and some features lost (ps4 etc).

I just picked up an H8314 for use on Verizon in the US and it has Android 10 already.
@Tom 23 can you explain more about what you did? Details? Are you using an H8314? On Verizon? I've read in the XZ2 forums supposedly now unlocking on Android 10 still breaks some stuff but now not the camera?
@williamgrant can you provide/link a list of exactly what breaks when you unlock the bootloader? Perhaps what breaks depends on what version of Android you're on when you unlock?
I'm trying to determine/weigh the pros and cons of unlocking to root are, if its worth it, what am I giving up...

Do you notice specific problems with the H8314 on Verizon? I have been delaying the Android 10 firmware update because I cannot seem to find many reports of "how it works on Verizon".

I've only been using it for a little over 36 hours, but so far nothing glaringly wrong. Keep in mind thought that 36 hours ago I was using a 2013 Motorola Moto X running Android 5.1... now I'm on Android 10... So there's probably stuff that is a bug that I don't recognize is a bug!
My wife's had her H8314 on Verizon for about 6 months and it's on Android 10 as well. If she's not complained to me about anything then that's good! Then again, she's likely not at the same "level" as XDA forum members are!

I too am interested in how to roll back to Android 9 if it can be accomplished reasonably easily without giving up a bunch of stuff.
I've been plagued with issues on Android 10. Even with the most recent update things have not improved. The two things most annoying to me are the drastically reduced battery life (more than halved!! it doesn't even last a full day anymore!!) and the fact that MMS do not download correctly all the time anymore. I've also noticed that camera quality has gone down somehow, even though Android 10 was supposed to improve it...

Hello folks
I successfully downgraded my XZ2 Compact (H8314) from Android 10 to 9 using that info: "https://forum.xda-developers.com/showpost.php?p=82087435"
but I had a problem, I downloaded (using XPERIAFIRM) 52.0.A.11.32 South Korea version (I'm from Italy, but Italy version is not available) , every thing work fine except LTE (4G) signal, as frequency of two country is not compatible, then I installed Android 10 again and all was ok.
So... now my question is: do you know where I can found 52.0.A.11.32 image customized for Italy?
Regards,,,Carlo

Hello. I downloaded some month ago rom for UK via Xperifirm. I deleted already ta-files according to description, and I added newsflasher (version 20) into same folder. I zipped complete prepared folder and uploaded it now. Should be okay for Italy.

Odidad and Lollixo, would love to know if I just follow from Step 4 of this guide if I am using this file Odidad provided? Have you had success flashing Lollixo?

Hi landsome. Probably I still have, but I am on a trip and I can't check this now.
I can do this not before Monday. When I'll find I will upload on Monday...
