Hello friends,
i am new to android world i buy used xperia neo back in jan 2012 when i check on its model number through android software it says mt15a
But when i remove the battery under that mt15i is written
and i am also not able to recieve OTA update it always fails also pc companion and update service are saying you have latest software
i wana know is it possible that previous owner put custom mt15a software on mt15i
also please tell me how i know that my phone is bootloader unlocked or locked ??
i wanted to update my phone to ICS how i do that i am right now on android 2.3.3 ( sorry for my poor english please help me guys )
The differences between the MT15i and MT15a are the 3G bands, MT15i is 3G 900/2100 and MT15a works in 3G 850/1900/2100. MT15a is the american version and MT15i is the international version.
It is possible to flash any firmware in any neo. I have flashed MT15i firmware in my MT15a and works fine.
You can check your device working bands by entering to the service menu *#*#7378423#*#* then select service info and then Configuration. This will also tell you if the phone bootloader is rooted or not.
You can flash your device back with a MT15i firmware using a tool called FlashTool, look in the forum for the instructions on how to use it and the different topics where you can find the links to download the MT15i firmware.
It is not possible to update from Android 2.3 to ICS via OTA.
hello when i tried it says working band/s:
gsm850, gsm900, 1800, 1900, umts_bc1, umts_bc8
Rooting status:
bootloader unlock allowed: yes
and in the model info it is saying mt15a but on the backcover under battery sticker info says mt15i
Please help me guys also tell me if i try to flash my device do i face 0% battery problem ??
And if you can give me any flashing link plz also help me in this thanks in advance
Also wanna ask can i simply repair my phone from Su service software??

Hi,
Your Phone's Bootloader is locked.
So in order to update your phone to latest ICS 4.0.4, first please install Flashtool to your computer from here
Now download the latest ICS 4.0.4 FTF file from here
After that, just follow the instructions on how to flash the FTF file. The instructions are provided here
****Before flashing, on the right hand side of the Flashtool, you will have "No Final Verification Check", make sure this option is Checked
If you face any issue, please feel free to ask
Hi aamir098,
Your phone is definitively a MT15i because of the UMTS bands, UMTS 1 is 2100 and UMTS 8 is 800. The MT15a uses UMTS bands 1, 2 and 5.
You can also try flashing your phone using SEUS:
http://www.sonymobile.com/gb/tools/update-service/
Or your you can use the FlashTool method.
There is a third option called WotanServer but this method is not free and they will charge you 1.99 € - http://www.wotanserver.com/en
Need help with mt15a 3g
Hello, I have a xperia neo mt15a, which 3g works on 1900, my phone is rooted, its bootloader is unlocked and I want to upgrade it to ICS, but, I can find only mt15i versions as far as I can see, my question is: if I flash one of these versions, would i loose my 3g capability?, and if so, is there anyway to take it back? I would appreciate your answer, thanks

Hi all
Let me clarify first that I tried searching this topic before creating a new post. I did not find anything to my specific question.
I have a Rogers branded X10.
I used the Proyaz video on Youtube to root my phone. Now my phone's model number shows X10i and the Build number shows R2BA020.
I want to unbrand my phone as well. I have found a couple of guides to debrand the phone but my question is will it work on my phone since its now rooted? Also because it now shows X10i as the model number do I download files for X10a (North America) or X10i (Most of Europe and Asia)? I am in Canada myself.
Any help would be greatly appreciated...

hey, 1st of all u havent mentioned that u originally had x10a or x10i? considering that ur location is canada, chances are ur riding on x10a,(Pl check it b4) as far as i know, for debranded ur phone u ill need a custom rom and then root it...so i ill say, follow the bin4ry's method in devlopment forum and then u can end up having a debranded phone along with rooted one..if u dont care about root, then u can try picking one of the roms in jerlepelea's forum in devloper section and flash it...hope this answers ur ques..
The chances are you have already debranded your phone as you've obviously flashed the X10i rom to it, your issue is getting back to X10a, so read some of the threads in the development section.
I have the same question as well (also with Rogers), but instead, I used the one-click root apk to root my x10. I want to know if I can still debrand my phone somehow..because it obviously isn't debranded yet..I still see that annoying Rogers logo when I start up my phone..anyone know? Or should I unroot then debrand??

hello:
I purchased a sony xperia Go which works for me so good, but the only problem is that the firmware st27i brought it only works with two bands hsdupa. In my country only works with the band 850 and not raise my smarthphone hsdupa signal. May indicate someone here or help me get or install firmware for xperia st27a go?.
regards
Firmware won't help here, it's a hardware issue.
But is no hardware problem, the bands are locked by the version of european software

Hey guys,
im really desperate about this. I searched for 2 hours but could not find a single firmware from german t-mobile. It doesnt matter which one, of ics or gb. I need the branded firmware for a warranty case. I hope you can help me.
not needed relock bootloader then use pc companion
Firstly thank you but could you be a little more detailed. Is the branded rom flashed when i restore with PC Companion.or what am i supposed to do with the tool? I dont have time to test it now.
Thank you for your replies,
alphaboy
The relock botlooader file you will find in xs development topic with all explication then use pc companian .branded firmware usealy mean some apps from your mobile operator
Nebunia lu Salam
If i restore with PC Companion i will get the stock unbranded firmware, but what i need IS the branded firmware with the startup logo and the apps.
Its about my local t-mobile shop accepting the warranty case. They could deny it if they see the device is unbranded..
Just a ideea relock bootloader and make a bootloop,the rest is up to you to lie them that you have receive an update etc...

Hi,
I recently bought a Z Ultra off ebay and when I received it realised that it was the XL39H Chinese version. It doesn't have gapps and most features only work in Chinese.
I'm wondering whether I can just flash another country's C6802 firmware onto it, or is this not possible due to the different model numbers? Are there any hardware differences between XL39H and C6802?
Someone said on another post that XL39H is just a sticker on the box and the phone itself still says C6802, but in my case it says XL39H in About Phone and on the device itself...
Thanks for your help!!
at the moment I would say you are good to flash either c6802 or c6833 firmware to the phone. Flashinf c6833 wont harm the phone but it will call itself c6833 and will have a LTE option (that will do nothing)
What version of the firmware is it on? if it is on .290 then follow my downgrade guide to get it to .532 if you want to root it. Then follow LordManhatton's guide for rooting, backing up the TA and unlocking the bootloader. Then get ready to flash away (fully charged of cause)
Thank you! I flashed a Hong Kong C6802 rom and it worked.
Xl39h->c6833
Hi, I flashed a native XL39H (chinese version) with a C6833 latest version using Emma (it asked me to choose the phone model and I put C6833), and I have noted that the sim card does not register when switching on, and the IMEI is disappeared in settings (unknown when doing *#06#)... what to do in order to recover sim functionality ? The IMEI appears if I connect to Emma and now it is like a C6833 but I don't know really what to do for resolve the problem. Let me know your help. I don't see now the popup to choose the phone model so in Emma only the C6833 firmware is shown. I would like the phone working as usual....even without 4G...

xl39h is c6802
try these ...might lead you in the right direction (maybe flashtool instead of Emma? I had to since I have a C6806)
EDIT
the links are old for the C6802 roms and do not work any more...but somehow maybe you will need to find this
Sony Xperia Z Ultra/XL39h/C6802_14.1.B.0. 471 (International Edition)

Thanks for the great information. i did follow and successfully flashed it with C6833_14.6.A.1.236_SA.ftf. my problem is the customer, who wants it "calling and texting like it previously was, when on the old chineese rom"! i am in shirt because I've no clue on how to bring back the baseband.
I was wandering if it is possible to enable all lte bands in M4, especifically in E2303 for south america?? Does this Phone and the other models have the same hardware?? Can I install an E2363 firmware to try o does the Phone bricks??
Thanks everybody!!! (im new in this world, dont be mad )

Sorry to tell you I havent. Same say you can brick the Phone by installing another firmware others says that nothing will happen because the hardware is different meaning this Phone cant recieve the bands that is not suppose to. I dont know. I've read other sites seraching for a solution to this problem with no luck. I guess we have to wait till a custom rom that works.
The model you buy works best in the region it's bought in. Some networks will cross-over when in a different continent, but not all, usually. You can't add frequencies to the phone whenever you want, as far as I know.
I have installed a e2303 software on a e2306 phone and it works fine, but still has the e2306 bands.
Maybe in the future there is a way...
