[Q] no LTE/data after flashing ExistenZ - Xperia Z Q&A, Help & Troubleshooting

This morning i flashed the larest ExistenZ 3.5 and everything went fine , phone works , can make calls etc... Was on wi-fi so never saw the issue,
Now the LTE/Data does not work , i've tried setting the bell apn , lookimg if I was on lte in settings etc.
Nothing seems to fix the issue, so before going back to an other rom id like to see if someone had this issue and a fix, since i really like the rom and if posible fix it. But if theres no fix ill go back no normal and find an other rom.
Thank you
Xperia Z c6616

I had a similar issue with 3.0 where I could only get a data connection after switching to airplane mode then back. It was really annoying. I'm not sure what fixed it in the end, but I did end up reflashing the baseband, and doing a clean install of 3.5 and now it works fine. Hope his helps.

I know this post is old, but do you have any news regarding to this? I've just flashed eXistenZ v4 and I have the same issue.
I reflashed again (full, fresh stock .228 install) and I got the same problem even before installing eXistenZ, as soon as the flash finished...
Thanks!

No Call, No Dataconnection...

Hi,
i´ve got a (big?) problem...i dont know why..but i cant make and get calls!
even the dataconnection doesnt work...
i have now the wgspolestras rc1 rom...i had tried the cm7...and the..i forgot..
i`ve made a clockworkmod restore...
nothing worked...
so i`ve flashed the baseband from 06.06 and updated the ril from the 06.06
no chance..no call...
what can i do?? i am a bit pissed off, no nice friday evening... -.-
i am new to the baseband & ril..so sorry if there is the answer somewhere...
hopefully someone can help me..
thanks
If nothing works, I suggest you do an NVflash. it's basically a clean flash of the stock ROM, which will clean everything (make sure you packup your apps on external sd card)
link of how to do it and the files you need - http://android.modaco.com/content/l...rom-release-v10b-dated-1300166062-15-03-2011/
thanks..i will look at this...i hope it will work!
EDIT:
The device is flashing....
after that, there is a stock rom on the device, right?
i have to root it again, and to install romanager with clockworkmod and install a rom?
EDIT2:
NO SUCCESS!!
the lg stock rom has started, i got an sms, then i tried to call....nothing!!
When i call my phone ->its busy...
sending/receiving sms seems to work..
you have to root your phone again, and install rom manager/clockworkmod.
try calling someone else, or try receiving a call. This is the gold standard, if this doesn't work, then there's not much else you can do.
i got a bit shocked!!
but i`ve flashed the newest vodaphone stock rom....
and it worked! (okay the internetsettings are different from my provider)
but that worked too
i am going to root and flash it now...it should work..
EDIT:
Its working...somehow!! Dataconnection is very bad...
i`ve flashed the RC1 from WGSpolestra...i can call in and out, but with data connection the signal is very bad...can i flash new ril and baseband?

just try out other baseband and ril, not every version is working for everybody ...
i`ve flashed the 606 baseband and ril.
but i dont understand why that happens...from now to then these problems..
anyway..the phone is working again..
Same problem..
Hey there,
Ive got the same problem.
I was using the CM Nightly Rom, but just one dat, I got an "X" instead of having any signal.
Dont have a clue why or what happend.
I tried other roms, but All the same problem.
At the end, I tried the NVFLASh, that works, But only with the 2.2 Roms.
Today i put the latest nightly on my Lg, and My signal was gone after half a day.
Weird, Weird...
Greetz
WyCkson.
i think that i found the problem....
wich launcher are u using?
i had used the pro plus launcher, but after a reboot all my widgets are gone (loading problem) so i switched to the adw launcher and no problem any more!!!
the phone works well now!!
How stupid is that....such probem because of the launcher!!!?
hello,
Is it possible it's sim card problem ?
Try with another to see.
bye
i`ve used my card in a other phone..no problem..
No Calls suddenly Don't know what to do!!!!
Suddenly NO Incoming Calls. Knew it the next day when my friend personally came to see.
Also got scolded from company.
Dont' know what is the problem. But 3 to 4 restart helps.
I feel I may be an IDIOT for buying this phone.

[Q] Wifi & battery issues on imilka's cm9

Hi folks,
I can't post in the dev section so I'm hoping someone can answer here instead. Searched imilka's thread but couldn't find anything that helped me. Wipe & reflash has worked for others but not me.
Wifi doesn't work for me. It worked when I activated it in the setup wizard after flashing the rom but after the first reboot it doesn't present me with any networks and it doesn't connect to the one I configured. I know the wifi device works because the mac address is identified in the status menu.
Also, battery time isn't very good. Less than half remains after being fully charged then left alone over night.
I have tried a full wipe & re-flash and also flashed the last version released yesterday. Does anyone have any tips or do I just wait for a new version? Seems weird that it works for everyone else.

Indeed, I didn't come accross any of these problems... I don't know what to say mate, might have something to do from whatever ROM you came from, some kernel remnants...but again, that's just guessing...
What I'd do in a situation like this would be to revert to a stock GB, use jBroid's kernel cleaner, and then try to reflash Chainfire's repack and back to CM. That's just what I'd do...
I'd try to do a factory reset first. That way you'll get another chance to setup your WiFi from scratch and see what transpires. If it fails, it's back to basics, most probably. Rooted GB --> ICS Repack --> CM9.
It's such a hassle to reinstall everything again.
I'm downloading a stock rom now and I'm going to try flashing the modem partition. Perhaps the modem in the chainfire repack I flashed before is not 100% compatible with my phone... Otherwise I'll just have to stick to mobile data.
Flashing modem made no difference so it's something with the ROM. Luckily I have a good data plan so I'll just leave it and see what happens in the versions to come. If anyone has an idea, feel free to let me know.
And thanks for your answers guys.
Suddenly it all works. Thank you Google. You're swell!

[Q] Problem with Slim ICS 3.5

Hi guys,
i have been using Krarvind's Slim ICS 3.5 for about 10 days and I absolutely loved it. I have just updated to 3.6 which caused my phone to bootloop
So, after an hour or so of labouring and trying to work my way back in to it i'm now back on 3.5, but I have absolutely no signal/3G coverage. Wi-Fi works no problems, just no signal!
I went in to the APNs and there is nothing there - I tried to save a new APN and it wont let me - has anyone encountered this before?
Thanks in advance
Haven't experienced this myself but a few things come to mind...
First would be to check if you imei number correct? If not you would need to restore this from a backup.
If IMEI number appears correct then I would try flashing the modem again or a different modem. Modems found here: http://forum.xda-developers.com/showthread.php?t=1158783
If this doesn't work you can try flashing 3.5 base and essentials again.
If that doesn't work search the threads and google or hope someone else can give you an answer. If you don't find any help then as a last resort you can flash a stock rom with Odin although I'm sure there must be an easier way.

I've had a similar problem, the updating to 3.6 just went wrong. No bootloop but loads of FC.
My solution has been going back to recovery, do a full wipe (wipe data/restore factory settings) and install 3.6 again. Everything seems to work now but I have to re-install and configure all my apps... :-(
Hope it helps...
Check in About > Phone
Under baseband does it say UNKNOWN ?
this happened to me once, need to reflash the modem. No need for wipes etc

Wifi Custom kernel problem

Update: Solved (just reflashed the ROM)
I have a problem here with my X8. So, after I have successfully unlocked my bootloader without the network problem, now I have a wifi problem. So what I did was: rooted my phone, unlocked the bootloader, applied a nAa kernel (before that I tried the MiniCM9 with the ICS nAa kernel), then I applied the custom ROM called JoyOS... In both cases(ICS-MiniCM9, and JoyOS) I have the problem when connecting to a wifi router, I cant use it. I know it sounds strange but I can connect normally with the wifi but still I cant use it... I mean when I try to open google.. or use anything with wifi (like syncing) I just cant... it says unable to connect to the internet. I am thinking its the unlocked bootloader problem.. but I am not sure. Can someone help with this please.
Maybe just reset router...
lol???
Thats not a problem with the router... I am using the internet via that router writing this reply.. please dont be stupid and post something smart.
EDIT:
Still waiting for a reply.. I really need a solution for this..
Have u tried connecting to a totally different router cuz that may be ur problem, I have a friend who had a similar problem with an android tablet that didn't like his router so give it a go it won't hurt to try
P.S did it connect when it was stock?
Sent through my X8
it did connect when it was on stock ... and I am not sure but I think it actually was working a little while I was using the MiniCM9 ICS ROM and on the same rom actually the problem has occured. Now I am not sure if it stopped working because of the unlocking and applying a new kernel or something else happened in the mean time.. Could it be I disabled wifi somehow? somewhere?
What rom are you using? i only say that because when i swapped from minicm9 to semc debrand engine both wifi and 3g stopped working but when i switched back to minicm9 it worked perfectly again.
Try a Full wipe + wipe dalvic cache (or whatever it is) and install the rom again, hope this helps
Now trying to flash miniCm9 again.. we ll see now.. will update in a few minutes
Update:
Great, , just flashed the ROM again and now working well. Thanks anyway for helping.
No problem glad i could help

[Q] Signal Issue

I flashed omars rom about a week ago and everything was going great until this morning. I woke up and have no signal at all. Rang my operator, they said there's nothing wrong with the network. I've tried everything I can think but nothing. I've flashed different roms, kernels and ended up using rsd lite to go back to stock, and still no good. Anyone have any ideas? Any help would be greatly appreciated!!
It can be hardware issue. If flashing full stock rom didn't help it shouldn't be software issue.
Download any app to enter radio settings and change to only 2g but it must be changed in radio settings, not just phone menu setting. If it wint help on stock full rom for 90% it gonna be hardware issue.
