[Q] Big Problems After Disconnection of USB Data Cable

Hi guys, I have a big problem, every time I disconnect my SGS from the pc my phone goes crazy and gives me FC's and none of the bottons work unless I take out the battery it will stay giving FC's for a while and then it reboots and keeps looping the reboot procedure.
The only way then to get to my phone is by factory reseting and deleting dalvik cache and battery stats via CWM. btw I had this problem since my first MIUI (1.7.22) and I've updated it every week but still no change.
Does any of you GURU's have an idea about this, it is really irritating, because practically I can not connect the phone to my pc to exchange data, with the original Samsung Android I had 4 or 5 ways to connect to my PC (Wi-Fi, DLNA, AllShare, USB Data Cable Samsung Kies and Samsung Kies AIR), but now I can not connect with any of those mediums.
.
try flashing it from 2.2.1froyo because if you flash miu from gb you will get lots of fc's, flash to froyo 2.2.1, then go to recovery mode, wipe data, datadata, cache, dalvik cache, and system and then do a fresh install. ive had problems like that before and it was because i came from gingerbread the bootloader wasnt correct to flash miui, also try fixing permissions from cwm hope it helps
I am comming from froyo, but thanks anyway, your reply gave me an idea.
I'll try another ROM, maybe cyano or maybe something more exotic like F1 SGS II or Fasty.
Have your tried ejecting the phone from your PC USB menu before unplugging it?

Yes, Sometimes it helps but most of the times doesn't have any effect at all!

[Q] All apps are crashing

Hello,
I have problems with my i9000. I am using MIUI 1.11.11.
The thing is that since yesterday I have serious issues with my phone. It happened before upgrading to new version of MIUI.
All apps started to crash, there is no exception. Starting from Google Services Framework untill standard bluetooth app. Every single one. I can't even check any e-mails, messages, I can't even make a call because calling app crashes too. I can't receive any calls at all. I rebooted phone, cleared caches, upgraded phone to MIUI 1.11.11 and nothing. I can't use my phone anymore.
When I pressed "Report problem" I saw for a second log with problem it said something about "data I/O error".
I think the issue is somehow connected to sdcard since I had problems with it before. It was always hard to connect my phone by usb cable. Actually... it was always hard to DISCONNECT my phone. I had to wait looong minutes (about 20 or so) till it finished disconnecting.
If you guys could help me, I'd be glad.
Thanks in advance,
v.

[Q] Xperia T - No Service, No Wifi, No Bluetooth.

My Xperia T recently started to have some problems with no apparently reason (no drops, no updates), I have No Wifi, Bluetooth, Radio or Service/Reception. I've tried the following things:
- Rebooting
- Turning Flight mode on and off
- Rebooting without SIM Card
- Wiped Cache/Dalvik Cache
- Wiped Internal Storage Data
- Flash a Stock .ftf
The phone is Rooted, Locked Bootloader, had CWM until i restored the system, now i can't install it again.
I was using "PureXT" (9.2.A.1.205) it worked perfectly for 7 months, i don't think that having that custom ROM had anything to do with this problems, anyway.
Any help is appreciated.
EDIT: I have no IMEI.
EDIT2: I send it to SONY, they couldn't repair it, so they send me an Xperia Z1.

Wifi getting switched on and off frequently

I am using AOSP Marshmallow beta 2 AOSP ROM on my Lenovo A7000 phone. Since then my wifi keeps getting switched off by itself and turns back on without any reason.
I also checked in my advanced wifi settings that my wifi is kept on during sleep and it was enabled. What should I do to fix this problem? I also flashed the ROM again by wiping data, dalvic, cache and factory reset but the problem persists.

GT N-7000 entered into a bootloop from a CM Security update

I have a Samsung Galaxy Note GT-N7000. It was giving me some problems with processor speed for sometime. Whenever I was wanting to do a slightly heavy work (e.g. clearing cache, cleaning junk on CM Security etc), it was going into a reboot. Thereafter, I zeroed in on the problem with CM security where it was doing rest everything correctly and was saying that there was too much junk on my phone (which was surprising cos it was scheduled for junk cleaning every alternate day) but as I was 'cleaning junk', it used to restart the phone.
Subsequent to this, i tried to go to app manager and tried to clear cache for heavier apps thinking it might b the reason for it slowing down but even before it could calculate cache and data allocation, it was restarting the phone.
When i tried to uninstall CM Security, it used to trigger the restart again.
Finally, I updated the CM Security to the latest version and as I did that, the phone went into an endless boot loop. Since then I have tried to recover it from the recovery mode through wipe cache partition but no joy. Had rooted the phone about 2 yrs back but I can't find the C-ROM. Can anyone help with the resolution of problem without the data loss from the phone?
