modem config and srm validation error - Sony Xperia ZL

hello! at some time i started noticing cell connection losing connection. i thought it's a problem with my custom rom so i decided to flash stock rom back. it was a customized RU tft for ZL C6503. After that the problem was pretty much gone but now i got an different problem: while moving for example in a car phone kept losing connection and then it got even worse by showing full connection but just not recieving/sending any data. i checked service menu and SRM VALIDATION was telling me unknown error, and same with CURRENT MODEM CONFIG. then i decided to refash but different one, german generic one, but the problem persisted. im guessing its a hardware problem?
Edit: nvm, it's same with all Xperia ZL-s. New battery seems to have fixed the problem

Custom ROM to fix wifi issues?

I bought a Defy second hand on ebay locked to T-Mobile UK. I don't have a T-Mobile SIM so I booted it up to test over wifi. However the wifi will only connect if I switch my router to G, and even when it does say it is connected I can't get on the net despite every other PC in the house working fine. I even changed the networks to open to rule out the security but with no luck.
Since I can't do an official update without a SIM (Or so the Motorola software tells me, I wonder what would happen if I went ahead) I was thinking of rooting and installing a custom ROM to see if this helps. However, obviously if I do this I won't be able to dispute the purchase on ebay so I want your advice before I plough on.
Do you think that a custom ROM will fix my wifi issue or is it more likely to be a faulty Defy that the seller has fobbed off on me?
Cheers.
from a technical point of view i dont think that the defy's hardware is faulty, i've heard of such wifi issues with some routers, even had some with mine with an early version of pays rom, so a custom rom will probably solve your problem.
and i recommend a custom rom over any official blur crapped software.
try miui.
Well I went ahead and put on the MIUI ROM but it has the same issue! Does this phone require a SIM to do anything? Do I need to be signed into a google account just to go on to the net?

I just updated my wife's defy to 2.2 this morning using MSU and it didn't have a SIM in it, it is for her birthday and i didn't want her to wonder why i wanted her SIM card.
All went smoothly.
Man i sugest first flash the nordic sbf FULL and after you flashed the sbf the play with custom roms like miui or cyanogen mine camed locked on orange i flashed the nordic 177 full sbf and after that it was all ok
RSDLite just gave me told me it failed when I tried the Nordic ROM.0x1700
I tried with the TMobile UK stock SBF file but it sticks in a boot loop between the Moto blur logo and TMobile. I flashed the 2.21 boot but no joy.
I flashed a T-MObile UK Froyo ROM and it boots and connects to open G wifi. Still no internet however.
i had the same problem connectiong to n-draft router, the connection got lost after some seconds. my solution was to edit the tiwlan.ini with root-explorer and change HT_Enable=0 to HT_Enable=1
you have to give the file write permission to save.
Chers for the tip, but now I discover this damn ROM is not rootable. At least, not with z4root.
Super one click did the job, but the file you mentioned already has HT_Enable = 1
***I managed to get the nor ROM to flash by running as admin and giving it a short name and putting it in the root directory! But guess what? Still no internet despite strong wifi signal. I don't know how to downgrade now to the original ROM. The one listed as T-Mobile UK 2.1 doesn't boot.
Now the phone isn't recognised by RSD at all. The white LED comes on though, there is some sign of life.
Bought a battery charger to charge the battery externally but still no joy when I plug the phone into a computer.
***nvm somehow it's working now. Flashing the nor ROM.
None of the SBF files seem to work now. Either I get a blank screen on boot or they get as far as the Moto logo (or android in the case of the nor rom) and loop.
Is it safe to flash other countries SBFs and then change the language?
can you try other people's wifi to see if you will encounter the same problem? if you don't then youneed to configure your router. flashing other country's sbf is ok, then use baseband switcher incase you have signal problems. wipe first before flashing

Intermittent data connection

My phone started turning on and off its 3g connection. Wifi works solid.
I'm on a good signal area. It's not like the 3g is on and I can't connect in anything.
The problem is that the phone turns on and off. It doesnt fix the 3g connection.
Also, Checkin service it's draining the battery a lot.
Looks like a software problem with Google Play Services and its Connection checking service.
Anybody have seen this problem?
thanks in advance.
Starting to worry right now. Did a factory reset on a flashed V10j KDZ and it didn't change.
TWRPed a 20A Lollipop rooted ZIP and it didn't change. Right now I'm trying to go back stock using LG PC Suite.
I can't understand why this can be a hardware problem because 3G actually works but it keeps constantly getting on/off in ~10 seconds intervals.
Looks like a bad system file that is messing with it.
EDIT: Also, the phone can't search for mobile networks anymore. I just tell it to do a manual search and it can't find anything.
What would this be? Modem file broke? WTH.

I have random disconnects/drops too, Although my 3G/LTE icon never actually goes away, just the signal.
Personally I would suspect your modem as #1 suspect.
Factory reset rarely fixes much, I would try re-flashing the phone.
If KDZ flash doesn't fix it maybe try a tot & dll flash using LG Flash Tools with modified megalock.
It definitely looks like a modem issue BUT it can be a your os. I had issues where my modem wouldn't flash from a stock flash on my S4, But manually flashing my modem would SOMETIMES work, I would have to flash the modem a few times usually before it would actually flash.
I had problems before but it was caused by network. Did you tried with different SIM card from other network?
I have the same problem and couldn´t fix yet... Didn´t try to use another SIM card to check if is a network trouble, but it´s driving me crazy to be without connection and a huge battery draining...
Any other ideas?

Just try with other network SIM. I had same problem long time back with Nokia n96, Motorola defy and some other phones. Some of time it helped to set phone only to use 2g network. That was happening the most of time when i used VIP network in Serbia.
Setting only 2g signal helped sometimes but after changing SIM card, problem was solved.
This problem happen to me without reason and after some time i tried same network again, there was no problems.
Probably a different SIM will correct the problem, because after a lot of trial and error changes I realized that the current Network APN (you can reach going on Mobile Networks inside Connections and Networks [translation] in the Settings) was faulty. I deleted the APNs and made a restore. (Delete and Restore are the only options inside Network APNs).
I imagine that changing SIM cards from another carrier will reconfigure the APNs and probably fix the problem.
I´ve tried a different SIM card and didn´t found any troubles, but when I put mine, the problem come back again... So it´s a problem with my carrier. I´ve deleted the APN settings, restart, restore, restart again and didn´t solve. I´ll call them to check if they are experiencing any network issues.

NOTE 3 Neo N7505 Lollipop Telephone problems

I already had this problem with ICS (I never upgraded to KK) but only occasionally - Ever since I upgraded to Lollipop (5.1.1 French version) the phone constantly loses the connection to the network (and of course also to the data) while WIFI works perfectly, rebooting the device things are back in place, until I move again(specially inside the house).
At first I installed the TWRP recovery (full wipe) and the rooted the phone, then thinking to solve this BIG trouble I flashed Lollipop again, remade the wipe of all, left all the bloatware that the first time I had eliminated - but it didn't worked - instead of the triangle where usually appear the notches of the connection there is an "access denied icon", and when I try to call appears the message: "NOT CONNECTED TO THE NETWORK" - by the way I can not receve calls too while in this state (unreachable).
Has anybody had the same problem or can help me anyway? Should I downgrade to KK or ICS? (but I'm reading that's not going to be possible from 5.1.1!) Maybe I can try flashing another Modem? The rest of the telephone is perfect, battery consumption is better, camera, movies, fluidity: everything is ok but the telephone!
My BASE BAND is N7505XXUDOK4 and my BUILD VERSION is LMY47X.N7505POUDOK2. Thanks

Z5 Premium Wifi and Tethering not working

Hi all,
New poster to the forums - I tried searching but no identical issues or solutions were found so sorry if this has been solved multiple times before..
My Z5 E6653 WiFi is not working - I go and turn it on and it will say "Searching for Wi-Fi Networks" however it never stops this or finds networks - even when there are many networks around.
I tried factory resetting, also flashed to stock 7.1.1 as per https://forum.xda-developers.com/xperia-z5/general/ftf-e66xx-patched-kernels-google-drive-t3688365 (steps 1-14).
Phone diagnostics say that wifi is working correctly. I tried repairing with sony pc companion tool however apparently my device is a "prototype" (bought off ebay) and repair is always cancelled by an error message.
With mobile tethering I can turn it on but the network is not found by any surrounding device..
At this stage I am leaning towards a possible hardware issue, as wifi was previously working at least a few weeks ago..
Would unlocking bootloader etc. and flashing a custom kernel help possibly?
Some further info:
Android Version 7.1.1
Kernel version: 3.10.84-perf-g99119bc
Build Number 32.4.A.1.54
Thanks

Hi, it seems that your wifi antenna is the problem, or antenna cable. But aniway it cant be fixed without opening your phone.

Thanks. My mobile data reception works so I assume the antenna is fine and it may just be wifi module / wifi antenna?

Wifi problems after flashing custom ROM

Hi all,
I am having problems with my wifi connection after flashing a custom rom. A few months ago I tried to flash lineage OS on the XT1685. This went wrong and the Phone was bricked. Last week I gave it a go once more and was able to flash back a stock rom from Motorola but something weird was going on. I couldn't get a WIFI connection ( no wifi signals in search wifi networks) and MAC-adress was shown as 02:00:00:00:00
I tried a whole bunch of possible solutions but none of them solved the issue. For example I tried to flash the WIFI-Fix, Tried emptying persist/wifi/.macaddr but there was nothing in it. How am I going tho get back my MAC adress! If the original MAC cant't be found is it possible to add another one? Maybe from an other phone or something?
Please help! I am stuck in this situation. Without WIFI the phone is pretty much useless.
Regards Remy
