Problems with the last update!

Hello i have a big problem.
Since i updated my HTC HD7 to the last update available i received it yesterday in Portugal , i have to take off the battery and reboot my phone because my phone losts wi fi conection and freezes many times!!! this is anoying! for example y already reseted my phone and to install all the apps i had installed from Marketplace i had to reboot 15 times because wi-fi stoped working or phone freezed !
anyone knows what is going on and can help please?
Thank you very much!
in your signature it says your using the NextGen Rom? actually my phone started freezing on me after installing the latest next gen.. however ive gone back to the original TMOUS rom and i still get the locking up and freezing. if fanct it doesnt matter which rom i switch to the freezing is still there. i have been unable to find any information as the freezing seems to be completly random. but ive had my HD7 for just about a year and havent had any of these problems until i flashed NextGen.. i wonder if its just a coinceidence??
Things tried:
Flashing to Stock Rom - Fail
Flashing to stock rom and getting updates up to the latest - Fail
Tried Several Different Radios - Fail
Tried other custom roms - Seemes to be worse on custom roms? -Big Fail
Tried low level format of sdcard - Fail
replaced sd card - Fail
Cleaned phone cuz ya never know - Fail
the freezing also seems to be completly random. but is more common when recieving calls. and manually using the power buton to lock and unlock the phone.
im not sure if any of your problems are similar to mine.
Hello!
My problems are exactly like yours!!! and they begun some time before i installed nextgen, i installed nextgen because i thoght it was a rom problem
I have a gess that is a problem with the battery a already bought two new batteryes from ebay i will let you know if that solved my problems
finaly i resolved my issue it was a radio problem!!! just that! i flashed the Radio_5.69.09.29a_22.50.50.21 and everything is working fine nowww!!!

[Q] Unrecognized SIM card

Hey guys,
So I got a quite annoying problem and I already spent quite some time searching the forums and google without results. Either the solutioins didn't work or the cases I found were unsolved.
Anyway, here is the story.
I have a xperia tipo (st21i) and I rooted it and unlocked the bootloader and flashed several kernels and roms to find the one I'm most comfortable with.
I used: CM 10.0, paranoid android, super jelly bean and performa v4 in case this is of any interest.
I decided to go with cm 10.0 and it worked fine until after one reboot suddenly my SIM card was unrecognized and it said I should restart the phone with a valid SIM card. I flashed different ROM's and went back to stock now but the problem persists. I really ran out of ideas and since I'm not really skilled and rich of knowledge beyond the point of flashing and the rough structure of android I'm a bit helpless here.
Any help is really appreciated and thanks in advance
P.S.: first post
I don't know if it would work but you can try it
Try flashing ics ftf it should work fine..
follow this may work
first flash the original .ftf file then flash cm10 :fingers-crossed:
This happened to me aswell, but it was a while ago, when I wasn't even rooted yet. Went to the shop to ask about it from them and they said SIMs can go outdated or something.. They gave me a new one and it was fixed. But if you decide to ask them about this, make sure you are on stock ROM and locked bootloader, also unrooted. Because if not, your device isn't under warranty, and they can blame it on that

So you are saying it's due to my SIM? It still works perfectly fine in my other phone (a samsung galaxy xcover s5690). The phone was used when I got it and I don't have any receipt or anything so I don't have warranty on my phone anyway right? Should I still visit a shop?
I also tried ICS and it didn't work either. I got the ftf file from that link : http://forum.xda-developers.com/xperia-j-e/development/rom-official-st21a-america-firmwares-t2302630
I tried flashing different kernels and roms already even after it refused to take my SIM but nothing helped. It didn't fell down or anything so I don't think anything went loose inside. Could it still be due to hardware failure?
heeey
I got almost the same problem
few weeks ago i found this thread http://forum.xda-developers.com/xperia-j-e/development/sony-xperia-tipo-dual-t2594389
about making custom roms works tipo dual by making it 1 sim not 2 well its ok with me so i used it and all was perfect
custom rom - working gsm - fast - smooth like i dont need anything else
but yesterday well my annoying gf was spamming calls while i was sleeping so i turned airplane mode On
then after i wake up i turned it off and suddenly the device can't recognize the sim any more the same problem this dude got
so i tried everything like tryin to swap the sim place - installing new rom - restore my old stock rom - hard reset - testing the sim - so i tried installing the last update stock ftf which is 11.0.A.6.5 i think it's like this using flash tools anyway it worked and the problem is solved now the phone is workin with no problems u should try it

I tried other phones aswell, it was working on them, but not on my phone. Weird, but yeah, I suggest you go visit them at the shop, they can probably help you out.

Strange Wifi Issue

Hi Team ,
I am having this very weird problem since morning
" I was using the wifi at my brother`s place just fine for a few days now . This morning the internet went dead slow ( on all the devices ) so we reset the router and it started working fine. Now the network is being detected / connecting just fine on all the devices at home ( 1 galaxy tab ,S4, S3 , Note 3 ) but my Nexus 5 is not even detecting the network. I was on stock Rom with element kernel. i did the following
1-) Played around with all the wifi related settings
2-) Factory reset twice
3-) Flashed a few kernals ( including the stock one )
4-) Flashed Mahdi Rom
5-) Flashed Stock rom
But the problem is still there. My Nexus 5 is not even seeing the wifi network ( it was working fine since this morning ). Just to check around i also created a hotspot network on my laptop. All other devices are able to see that hot spot except for my Nexus :crying:
Also
As i am visiting my brother outside country , i do not know anyone else here where i can go and connect to a wifi network. Although the phone is seeing Near by wifi networks just fine. I also cannot check the router settings etc as my brother has lost the id/ pwd
I am getting out of ideas now , and also bombarded by the family on using a nexus instead of a galaxy phone ( not that i care :silly: )
Any help would he highly appreciated

Check if your wifi settings are on 5 ghz or 2,4 ghz only, check if your mac address is shown and try to flash franco kernel
Tried both the 5ghz and 2.4 ghz frequencies but to no avail. I can see the mac address , flashed the latest franco kernel but situation is still the same .
Edit :
Just got the problem resolved . Apparently the phone does not have a sim installed ( i am out of country ) . I just inserted a local sim in and things are back to normal
Very strange problem. Is there any explanation to this ?

Samsung S7 Edge, please help!

i just bought an s7 from craiglist, but this cellphone has a lot of random freezes !, i already did a factory reset with no success, i also already tried safe mode and still freeze every 5 or 7 seconds, it freeze/lag for like about 2 or 3 seconds, Then is good... then it lags/freeze again
no SD card in this phone!
i was wondering if is a problem with the cellphone itself or its probably something wrong with the stock ROM? i was thinking about flashing the phone with a custom ROM or another stock ROM so it maybe solve the freeze/lag problem
