[Nexus 4 Q&A, Help & Troubleshooting] morox:
Hi, My name is javier, I have bought one nexus 4 8Gb orange phone, but it is sim-unlocked so I can use my MVNO ( mobile virtual operator network) But I am unable to use 3G or WCDMA band in spain.

I Know here are some problems about MVNO and 4.3 and 4.4 and 4.4.2 Android versions, but my problem is not this one. On a Vodafone SIM Card, I am unable to get internet also on this unit. The rest of the phone works flawessly, but 3G does not. I am starting to think that GSM chip is broken. But Hey 2G Networks works well no signal lost, perfectly clear voice on dialing, and constant 20kb internet data speed. No matter is an MVNO or a real operator like Vodafone.

Searching the net, i came over this:

Nexus 4 Suffering from 3G and 4.· Upgrade

And for all of you that are not going to take a deep read, let me tell, that they say there is an error on 4.3 and newer Android framework and Radio Baseband version. So people get unconsistent 3G connection. Well mine is really consistent. No conection at all never. So I think this is not my problem, although I have tried a bunch of roms even all google ones, all basebands and a couple of sims from diferent company.

Anyway, a quick fix is quoted here: Quick 3G Fix But I do not understand what is this or what I am supposed to do with that. Can someone help me with this?

And, after that, I start to look at something more, like Sim Unlocking is snot well done and 3g Band is still locked. Havent tried it with Orange sim as I do not have any. Is there any secret menu where network locks are shown?

And moreover, How can I trace what is happening to my chip? If someone has made hybrid basebands to unlock 4G, there has to be a way to track what is happening to radio basebands while they are working...and perhaps, I can gather some good info to work with...

One more thing on *#*#4636#*#* menu, I can force WCDMA or GSM or the rest options, If I use Force WCDMA, I get signal lost for ever, If only GSM or WCDMA Preferred, it has signal but only gprs internet conection. This is with ONO (MVNO). But with Vodafone, I get HSPA Conection but no internet at all. :confused:

Really annoyed with this, hope someone is able to help me with this.

Thanks to all in advance.
[Nexus 4 Q&A, Help & Troubleshooting] morox:
Nobody? well i will try to find out myself.

Anyway I have started to know something about android tracking with logcat, and would like to know if there is any way to check all the traces of the modem to check if the chip is faulty or is a driver issue and i have to learn to modify it myself. Thanks.

how did you install cwm is it by mobileuncle or this method

[Sony Xperia C] Xenon1978:
I flashed it but few menus are missing in recovery like back to main menu pls can u check it
[Sony Xperia C] TacoNikky:
Swipe your finger from right to left. It means to go back ;)

Nothing missing in that recovery. This is Carliv Touch Recovery.

woooooooow finally :laugh: . aslo i will try to upload the new firmware guys i updates my phone to 16.0.B.2.13 and i successfully installed cwm because my bootloader kept J.2.6. time for the developers now:good:
[Sony Xperia C] indra7x:
Help me :(

may I ask rom MTKDroidTools backup of tools for use in flashtool ? :D
[Sony Xperia C] :
I tried this on B.2.6 and it just resulted in a non-booting phone...
[Sony Xperia C] TacoNikky:
Didn't work me either. There should be a trick. Did you do it while your sd card removed?
[Sony Xperia C] temmy45:
are we sure if the picture in the previous page is actually xperia c cos the led indicator of xperia c is below the screen but d pics above has is led indicator at the top if am right
[Sony Xperia C] TacoNikky:
Second time I tried and it failed again. If you can share your new recovery.img with us, maybe we can flash it with mobile uncle tools or something like that.

Edit: I used the recovery.img file which is created by cwm magic for flashing with mobile uncle tools and same thing happened. Flashing process is successful but our recovery.img is the problem. Anyway if you share your recovery.img i believe we will have CWM as well ;)

Thanks
[Sony Xperia C] rocker00:
i don't know how to extract recovery.img...tell me the steps and sure i'll upload it
[Sony Xperia C] metalrules321:
Suffice to say, this CWM wrecked my phone too.

TacoNikky's idea seems to be good. But I also dont know exactly how to extract the recovery.img
[Sony Xperia C] Xenon1978:
You can use the steps to dump

[Sony Xperia C] rocker00:
here is the recovery.img

[Sony Xperia C] Xenon1978:
can you pls upload to any other file sharing.Iam not able to download frm 4shared.
[Sony Xperia C] rocker00:
attached.
[Sony Xperia C] TacoNikky:
Thanks for your share mate.

I flashed it with mobileuncle tools but same thing happened non-booting phone. That shows us something blocks us to flash recovery at the phone.

Did you patch android before installation?(Like removing signature verification)

Anything you remember, share with us and we try like that.
[Sony Xperia C] metalrules321:
Well Im currently in repair mode, so I wont be able to test it out

Thanks rocker00

Edit : Seems like only two people managed to boot it succesfully

Or am I missing something here ??
[Sony Xperia C] Xenon1978:
here is the patched services.jar frm deodexed rom pls check it
[Sony Xperia C] rocker00:
ohhhh maybe you are right...i'm using xperia xposed by Serajr form this

http://xdaforums.com/showthread.php?t=2612179

i thought it has no relation but lets try all till it works with all of you
[Sony Xperia C] Xenon1978:
Right now Iam at my friends place so I don't have usb cable to check it.

Use the above patched Services.jar & abd push it & delete the odex file.
[Sony Xperia C] TacoNikky:
Did you deodex your rom before recovery?

Was busybox installed?

I am repairing mine with PC Companion, as soon as i get control of my phone i try above.
[Sony Xperia C] rocker00:
no...am using stock odexed and yes busybox

was installed
[Sony Xperia C] Xenon1978:
Follow post # 18 to root your phone.

next update SU to su pro anything above v.1.6 & above

install Busybox.

somet times we don't get full root.

use the services.jar [patched] push it lets hope maybe this works.
[Sony Xperia C] TacoNikky:
I am gonna install xposed and serajr. In serajr, I think system / super user mode was on, wasn't it?

Edit: Framaroot for root but in framaroot what did you choose?

Boromir

Faramir

The other one
[Sony Xperia C] rocker00:
right..it was enabled
[Sony Xperia C] Xenon1978:
use this Boromir
[Sony Xperia C] rocker00:
i only remember and sure that i choosed the first one but i don't remember the name
[Sony Xperia C] TacoNikky:
OK guys.

Phone is back now, if you remember anything else, just tell me.

I start from rooting and I will try the steps above.
[Sony Xperia C] rocker00:
no thats all nothing else but i want you to update supersu to the latest version just in case
[Sony Xperia C] Xenon1978:
update su to newer version pro.
[Sony Xperia C] TacoNikky:
I did it all the time, i am going to update it again.
[Sony Xperia C] metalrules321:
*Fingers crossed people *
[Sony Xperia C] TacoNikky:
If I change it with root explorer, does it work? I am at this stage now. Waiting for reply
[Sony Xperia C] Xenon1978:
I used root explore to move but got boot loop, so its safe to use adb to push & delete

make a folder done_frame & copy services.jar here & place the folder on sd

use the commands

adb shell

su

stop

mount -o rw,remount /system/ /system/

cp /sdcard/done_frame/* /system/framework/

rm /system/framework/services.odex

mount -o ro,remount /system/ /system/

reboot
[Sony Xperia C] rocker00:
i didn't do this i just used xposed xperia so my self i don't know it will working or no but in my opinion don't do it
[Sony Xperia C] TacoNikky:
Before flashing just check these guys

-rooted with framaroot boromir

-supersu v1.93 updated

-xposed and serajr installed and super user mode on

-Didn't change services.jar

I am starting to flash recovery with magic cwm program
[Sony Xperia C] rocker00:
yes that's all what i did...hope it works this time..go on mate

mate...don't forgot to install adb drivers its very important and sure enable usb debugging on your device
[Sony Xperia C] TacoNikky:
I installed adb drivers an usb debugging was enable. But no boot again :(

Did you install these drivers and this version cwm magic?

(The one you uploaded)
[Sony Xperia C] rocker00:
wtf is wrong !!! yes those i uploded.i don't know what the hell is wrong !!!
[Sony Xperia C] Xenon1978:
ok which windows os are you using. Sometimes if on win 8 x64 unsigned drivers won't install/work correctly check it.
[Sony Xperia C] TacoNikky:
I agree with you. But i discovered a new thing.

While phone does not boot(connected pc with usb cable), press power and volume down green led starts to light. Like we flash with PC companion. I think its software flashable mod. I am going to try SP Flash Tool now with this new method ;)
[Sony Xperia C] rocker00:
am using windows 7 x64
[Sony Xperia C] TacoNikky:
Tried it with win7 - 32bit and win8 - 64bit(unsigned driver things changed while booting) I think it's phone related issue(Sony blocks these things)
[Sony Xperia C] Xenon1978:
check the image in the above post
[Sony Xperia C] TacoNikky:
Drivers were correctly installed. I checked device manager before flash, it showed the same in the photo.
[Sony Xperia C] Xenon1978:
ok let me try Iam reaching home within 30mins & let you know.

also why don't you try on deodexed rom
[Sony Xperia C] TacoNikky:
I am trying alternatives if doesn't work, i am going to try that as well. I really want that recovery
[Sony Xperia C] Xenon1978:
not working I tried it now
[Sony Xperia C] TacoNikky:
Ok mate thanks.

What should be wrong with flashing recovery? Not just rocker00, merabini78 also installed this recovery. Maybe he can help us as well.
[Sony Xperia C] metalrules321:
Well, I tried it as many ways as I could possibly think. And the end result was the same as you guys

I contacted merabini78 and asked how he did it, he just told me that he followed the steps written on the page and voila...got the cwm. I was hoping maybe I could do it too but no, I failed too.

It just seems to be an impossible task and I wonder how the people on the other site managed to do it, although judging by the comments written there, it showed that the success rate was 60-40% .
[Sony Xperia C] Xenon1978:
now after this iam not able to repair my phone

pls guys let me know how did you flash the stock rom
[Sony Xperia C] metalrules321:
Did the pc-companion came of any help ??
[Sony Xperia C] Xenon1978:
no its not showing anything.
[Sony Xperia C] rocker00:
press and hold power+volume up till the device switch off and then repair with update service.

am really sorry for all you guys i really don't know what's wrong i tried to do my best :(
[Sony Xperia C] Xenon1978:
no its not showing in update services

any other way pls
[Sony Xperia C] TacoNikky:
It does not show at first. Click on the repair my phone, it starts to download firmware then says connect the phone. At that stage press power and volume down about 25 seconds. There will be green light at bottom of phone, then it repairs
[Sony Xperia C] Xenon1978:
there is no repair option in update services guys
[Sony Xperia C] rocker00:
your phone is off now right ?
[Sony Xperia C] Xenon1978:
yes phone is off holding power+volume
[Sony Xperia C] TacoNikky:
Use Sony PC Companion, click support zone / firmware update / repair my phone(blue font)
[Sony Xperia C] rocker00:
launch update service then press and hold volume down and connect your phone and keep pressing volume down till you see the green led then the update service will give you the option to reinstall the software
[Sony Xperia C] TacoNikky:
rocker00 can you please check the software and post a screenshot.

Dial *#*#7378423#*#* > Service info > software info

I want to know the difference between our device, may be there are 2 versions of Xperia C.
[Sony Xperia C] Xenon1978:
with Update service is not working

Iam using Sony PC Companion now.
[Sony Xperia C] rocker00:
here mate
[Sony Xperia C] TacoNikky:
Is it working?

When it's done, phone boots but there is a green android robot on screen. Just hold volume up and power when you see it.
[Sony Xperia C] Xenon1978:
no its not working
[Sony Xperia C] TacoNikky:
I also attached my software info. There are differences at Boot Version and Customization version. I think it does not work because of boot version.

Guys please check yourself and we compare it. We need one from merabini78.
[Sony Xperia C] TacoNikky:
How? Is it because of deodexed?

In this situation everybody used PC companion and it worked.
[Sony Xperia C] Xenon1978:
before I had flashed using update services on deodexed
[Sony Xperia C] rocker00:
Customization version relate to the region i think so has no relation but maybe because of boot version.waiting for merabini78.
[Sony Xperia C] Xenon1978:
ok I got it working in SUS. after hard reset now it started flashing

thanks
[Sony Xperia C] rocker00:
good news i was really sad for you.don't do anything related to this cwm till we find whats wrong or whats different between my device and your devices
[Sony Xperia C] Xenon1978:
ok thanks bro lets us hope we get a working 1
[Sony Xperia C] prashh17:
Alright then rocker00, you have Finally installed cwm on your device.. Have you tried porting some apps like Social camera or porting some ROMs for locked boatloader.. Please do us inform..

[Sony Xperia C] Xenon1978:
how did you managed to get it working.pls lets us know
[Sony Xperia C] TacoNikky:
I think there is a misunderstanding, it didn't work on my device.

I mean two of the xperia c owners managed it to work.

[MENTION=4657061]pangeranpas[/MENTION]

My friend bought me this phone from United States.
[Sony Xperia C] :
The reason why it doesn't work is because of the S1boot versions on our devices are more restrictive in the signature check than your's.
[Sony Xperia C] metalrules321:
It seems like sony and mediatek locked this phone with a frickin steel !!

>:( Failures like these leads me to more frustration and want to send both companies a very angry email
[Sony Xperia C] Xenon1978:
ok here is mine 1274-4304-2.14.J.0.68
[Sony Xperia C] :
This isn't because of Mediatek, it's Sony which have decided to use their own bootloader which is locked down on the users end. All other Mediatek devices comes with unlocked bootloader, it's Sony who made this decision.

Same as me then, that means that the 0.68 bootloader version is impossible to flash CWM on.
[Sony Xperia C] pangeranpas:
Oh crap, so it causes by sony, damn..:mad:

[Sony Xperia C] wabaki94:
1274-4304, 2.14.j.2.6
[Sony Xperia C] superdragonpt:
This is really weird.

I already made an couple of CWM in the past for you guys.

(I dont own the phone btw).

As stated, since your bootloader is locked, it's just impossible to flash into the /recovery partition.

NOW, IF indeed an couple of guys managed to flash an CWM, well then, it seems you got an unlocked bootloader in your Xperia version.

What you need to do is backup all your partitions with the MTKdroidTools, then i (or other member) can compare your sec.ro.img (this is the mediatek bootloader), if they are different (and must be), other users can simply flash that unlocked bootloader with the SPFlashtools (use the version i uploaded in the other thread), then flashing cwm will be simple as eating pie :)

If you need further assistenace, just drop me an PM.

Regards
[Sony Xperia C] :
Yes, that's a good idea but I'm not going to try this on my device as I'm not able to get my device repaired if I brick it.
