Hello everybody,
I have a carrier unlocked Xperia Arc. I had flashed .58 firmware, which I had rooted with Zegrush method (bootloader is locked). It was working fine for a few days, then suddenly the 3G stopped working. I am still getting the EDGE (2G) data transfer.
Since my SIM when inserted into my friends Samsung i9003 was giving a good 3G connection and also my friends SIM when inserted into my Xperia Arc was unable to connect through 3G, I thought that the fault was in my Xperia Arc only.
I have
1) Checked APN settings, they are fine. Downloaded and installed them again to be doubly sure.
2) Did a soft reset
3) Did a hard reset
4) Used repair through PC companion
5) flashed .62 firmware with accompanying baseband
6) flashed .42 firmware with accompanying baseband
7) checked network mode. Its WCDMA(preferred)/GSM. On switching to WCDMA, the 3G connection works for a few minutes and then the whole connection drops.
8) I read in some discussion boards that a similar problem arises if the SIM card lock is used but I am not using it.
Is it a hardware defect? Should I unlock the bootloader and flash one of the custom ROMS?
Any other suggestions?
Please help.
Thanking in advance.
Maybe your carrier have a slow-down after using too much data traffic?
And post in the correct section.

Hello!
I successfully rooted my phone. But I got one BIG PROBLEM i can not conncet to my carrier even though my sim-card was recognized by the phone. So what went wrong ???
I installed a couple of custom roms:
B 0.7
cyanogenmod (stable; legend)
and I tried to unroot it with
RUU_Legend_Voda_AT_GER_Mobilkom_1.31.177.2_Radio_47.26.35.04_7.05.35.26L
RUU_Legend_Vodafone_AT_GER_Mobilkom_1.31.177.3_Radio_47.26.35.04_7.05.35.26L_release_126862_signed
RUU_Legend_Froyo_S_HTC_WWE_3.15.405.3_Radio_47.51.35.17_7.13.35.05_release_160328_signed
but there is still no connection to my carrier A1 [Austria]
Switching between GSM & WCDMA brought no success.
The only time I got a conncetion(2 out of 4 bars thats way to low...) was, when I placed a friends sim-card in my phone.
Hey folks.
Not actually an x10 user myself, but someone I know with an x10 is having an issue.
he bought an unlocked x10 from europe, and has been using it with Rogers for a long time now.
After running the gingerbread update, he's lost the ability to connect to the towers. The APN settings have disappeared, I restored them, but he's still unable to connect. Tried manually selecting a network. On WCDMA only, nothing shows up. On GSM/WCDMA mode, the only option is 2G (Yes, there is good 3G service in the area). If I try and connect to 2G, it tries to register, then returns an error saying the SIM does not allow connections to this network. I tried with both my SIM and his, same result.
I did a quick check, and I see the x10 european model supports 900/1700/2100, but it obviously also supports 850/1900 considering he was connecting before the update.
My question, has the update changed the radio making the phone unable to recognize the 850/1900 HSPA bands? If so, is there a way to go back to Froyo without rooting/flashing a custom ROM?
Thanks for your help
crap, sorry, please move to Q&A. I thought I clicked QA, my apologies.
It doesn't also sorry the other bands, that's impossible.
The radio hardware is different.

hmm.. unless he's been on only 2G the entire time?
Still doesn't explain why he's unable to connect to 2G at the present though...
download flashtool 3 and then find an tft file for the firmware you want, this will wipe the phone

thanks, I'll pass that along.
Does it require root/unlocked boot?
nope because you are only puting back on original Firmware, also just try SEUS to factory reset phone and reinstall firmware should kick it in to gear
Hello, I had successfully flashed my LG G2 (D802) from stock to CM 10.2. The sim card was recognised and joined immediately to EE (UK - Mobile Network *T-Mobile/Orange*). During Christmas I tried flashing a new nightly from Cyanogen Mod (11), however I had an outdated clockworkmod version (even though I couldn't update it further). I couldn't launch back to CM 10.2, as the data was wiped when trying to flash CM 11 (Nightly).
Due to not having a back up file, I reverted to factory settings first, then wipe 'all' data off my phone using ALL the options avaliable on CWM. I then had to use 'adb' to push CM 10.2 back into to the phone. It successfully flashed and it was running stably. During the set up pages, CM gave me a pop up to look at sim card instructions to 'get it working', i thought this was a minor problem and couldn't to set it up. When this was finished, gave me everything (WI-FI, bluetooth etc.), however I didn't connect to my Mobile Network 'EE'.
I set 'Data Enabled', Network Mode: WCDMA Preferred.
I tried automatically/manually connecting via the CM settings, but response was 'Could not connect to this network. Please try again later.'
So no luck so far in connecting the phone function back up.
I would be truly thankful if everyone could help with a solution. ^_^
Many Thanks!
I've found out that the phone is locked to a HK network, but I am currently studying in the UK. The problem is that I can't unlock the phone in the UK with using the HK network; I have a HK sim card as well as UK, but since the phone is locked I can't use a UK sim card and the HK sim card doesn't seems to register UK Networks.
Anyone got suggestions to bypass this?
Hi all,
I've had my phone locked on Tele2 (CRO) network which I needed to unlock to be able to use T-mobile SIM. I've used Odin 3.04 and followed the instructions to update modem to I9505XXUFNB9. I've managed to unlock the network this way and use my new SIM but the connection (both phone and mobile data) kept switching on and off constantly.
After that I've tried another firmware, namely I9505XXUFNDG for T-mobile but the problem now is that mobile is almost always off with no possiblity to connect and WiFi is blocked completely (security notification "Your device's security has blocked an action").
Basebands registered properly after every flash.
Phone is not rooted and me not being a power user would just love it to work as it was intended to
Followed the guide, all firmwares downloaded from here
Appreciate any help.
Might be onto something. After reading through this post seems I need to apply WiFi fix but I cannot tell which one to use for my phone (I9505XXUFNDG) as it's not posted. Kernel version 3.4.0-481100.
I've tried I9505_WiFi_FIX_MDM.tar and I9505_WiFi_FIX_MDF.tar but they just messed up the phone completely.
Thx a lot.

Hi ,
you should flash the fix for the modem you have installed , try following:
Flash another modem from the list there
Now flash the modem wifi fix for that modem
If still in trouble re flash stock and start all over again.....

Thx, did just that and now it works properly.
Much obliged.
a problem started to show recently; when i select LTE/WCDMA/GSM for auto connect network mode when the mode switches due to signal availability it doesn't get reconnected. i.e. while under LTE it works fine but if i move and get out of reach it should automatically switch to slower network which it doesn't. this works fine if i select WCDMA/GSM then the switches are fine but LTE is not available under this.
one more thing i noticed since i'+ve flashed the phone is that the upper part of the phone gets very very hot (a lot more than before). since the flash i've also had to replace a microSD card which died within weeks (not necessarily connected but worth noting).
any suggestions welcome.

Hello everyone!
I've got my Sprint s4, unlocked it to use in Canada and flahed JFLTE-GPE. Since then i had no problems for half a year, but this autumnthe ROM got an update. It has lost all the personalisation and other stuff and moreover started rebooting randomly. I decided to switch to OCT-L, and the phone couldn't connect to the network. I tryed different settings and it either was written "Sprint" or "International" (at the network status). But also there was a setting at which it was rapidly changing from "Sprint" to my SIM card network. I flashed JFLTE-GPE back, but nothing changed except it didn't connect to my SIM card at all. I flashed OH1 modem (saw it somewhere on the forum) but it didnt give anything.
Help me anyone please!:crying:
