[Q] 3G not working
I have Lumia 920 Black on EE in UK.
Last month when Amber (french one) got leaked, I installed it and tried straight away.
It wasn't big difference to me in fact it had a bug where if I create an all day calendar entry using google account (not tried with Live account),
it will save the even entry as day before?
It bugged me so much so I decided I will install EURO Dev version.
So I did and everything seem to work fine untill I go outside my house.
I kept on getting no signals. And when I had signal it was constantly on EDGE. Never on 3G.
I did reflash and restart and all it doesn't seem to help. When I restart the phone I get 3G briefly for seconds until it loses service totally then come back with full EDGE signal.
I have found a old firmware RM821_1232.2109.1242.1010_RETAIL_eu_euro1_342_10_9 7021 and flashed it. And did update through OTA.
Still no 3G. I called EE today for help. They told me it could be the sim.
So I tried on my old iPhone 4 and its all good. I get full 3G.
Anyone know what may be the problem? And if EE offers a repair, will they found out that I've playing with flashing the device and tell me its not covered by the warranty?
Thanks you all!
