Sony Ericson E15i (Xperia X8) restarts in GSM

Good time to all, recently bought sony ericson E15i, aka Xperia X8, the fact is that if the phone flashed the latest firmware and put the SIM card from the operator Beeline, it restarts in 2G, and 3g works fine (same observed in vivacell operator in Armenia). The problem is easily solved by flashing the old firmware radio (with radio modules M76xx-tsncjolym-53404015 and rebooted with M76xx-tsncjolym-53404015006 works fine). But the problem is that the 006 does not work on Wi-Fi, and can `t put the firmware above 2.1 (I want to put a modification firmware, but all require radio version 015). I want to know your opinion, can I? (hardware or software equation) will solve this problem to work properly in networks 2G. There is? Modification of the firmware on the radio module 006? (This problem occurs also with xperia X10)

Please help me, My problem is actually yet

[Q] Need Help !! My C6602 often dead

Hi sir, I need your help.
this problem I guess starting when I tried to change my network mode through xposed (FYI: in my country ID doesn't fully support LTE yet, but I try enable all network type) then my phone automatically set to LTE mode and suddenly got turn off when I unlock screen. at the moment I realize that my C6602 isn't LTE
FYI I tried to solve it, here is I've tried:
-Flash stock FTF
-Restore NANDROID but failed (CWM error while restore /system, I've regenerating md5 and it's fine)
-Relock BL
-Remove SDCard
-Remove SIMCard
few main problems:
-when I discharging, sometimes it work normally (didn't turn off) except if I setting my clock time, open camera, and few apps it's suddenly turn off
-however if I tried turn on my phone, it's stuck at sony logo then turn off again and I can't turn it on except if my phone charging it's can boot perfectly
-when I succeed use my phone (with charging attached) then I check network mode there's LTE mode !! how can I fix this network mode? I desire like before (WCDMA preferred/GSM, there's no LTE mode)
so sorry if this thread similar with others but I'm already search and surfing any thread it no result

which country or carrier is the phone from? make sure you download and flash the appropriate ftf that is only for c6603. flash it with flashtool and it should boot up nicely. if you are having troubles on 4.3 ftf, then possbile try the lower version (4.2.2 or 4.1.2) and then connect it with pc suite and update from there

Did you try to dial *#06# to check ur IMEI? Try to reflash .ftf file via Flashtool (find the one for ur region).

[Q] Update Help

So today i got a new unopened xperia Z from a friend for free
So i went on connecting to my WIFI it shows that the device needs to updated to frimware 10.31.A.2.67
(which i later learned that it was a update released in 2013).But i didnt update.
My phone is in frimware 10.1.A.1.434 which i guess is an old frimware.
Can i directly update to a new frimware ?Can i update it to 4.4.4 or newer versions and also how?
My device is xperia Z C6603

You can install SONY PC companionon your PC and use that to update your phone.
If that still doesnot help, you can use flashtool which is unofficial way to upgrade/downgrade your phone.
You would need FTF from general section and also flashtool which you can get from here. Make sure the FTF is device specific or your would end up bricking up your phone

You can search xda for how to use it. If you still have questions, quote me and I would be glad to help
