[Q] Defy Network loss/Random reboot - Defy Q&A, Help & Troubleshooting

Hello to all,
After flashing the "4.5.1-134 on Android 2.3.4 NO ROOT NO DOWNGRADE to Android Froyo use Nandroid(rooted) + SBF fix to keep the downgrade ability and root" my Defy randomly reboots and loosing network conectivity, there is also a celular data notification that never goes away if I disable the data conection.
Is there any solution for the random reboots ?

It was a SIM card problem
After reading/trying I think all of the so called solutions about the up above problem ( and I mean by that, trying all costum ROM out there) the random reboot problem was caused by my Orange SIM card !!!, SIM card tested on a second device ( HTC DS)and it was the same network loss and one reboot during the day, the Moto Defy was constantly rebooting, changed for a vodafone SIM and there was no reboot at all.

[Q] No Sim Card - problem in Orange San Francisco

I have this problem for the past two days. It was working fine for a week and yesterday I tried installing clockwork, I installed androot and rooted my phone, installed super user and Rom manager.
While restarting my Rom in recovery it got struck and I had to remove the battery to reset it.
After that I booted into stock orange rom and the sim was not recognized.
I am not sure whether this is a hardware problem or the problem with software.
I tried these things before posting here
1. Tried various custom roms ( CM7, Swedish Spring Rom) to check if the problem is with software. While installing SS2 I tried replacing the sim and this time I did it a bit different than I usually do, instead of putting the sim and then the battery I did the reverse and when I booted into SS2 I got the sim detected. I had left that in my table the whole night and what I saw in the morning is that the phone again displaying the same old "No Sim Card" message.
2. Had put a paper flap above the sim while inserting the sim - Not worked
3. With a sewing needle I had raised all the 6 sim contacts in the phone and then inserted the sim - Not worked
4. Pushed the sim towards the battery side a bit - Not worked
Guys please help me in resolving this.
Whether this is a hardware or software problem and how can I debug these kind of issues.
Please help.
Did you try inserting another orange sim? you should send it back to orange :/
Have you tried the Sim in another phone? I had this problem and the contacts on the sim were worn.

Sim suddendly disappeared

Hello everyone !
I have some issues with my sim card on OpenBeta3 + custom kernel (Bluspark).
One day, without doing anything, sim card suddenly being not recognized on each slot, swapping slots or rebooting doesn't have any effects.
(My sim card is good, tested with an other phone)
Catlogs says about a "CARD_IO_ERROR" when sim disappear.
I've done full factory reset or resetting network settings and it didn't solve my issue.
Then i flashed full stock rom by fastboot way + reset network settings, it seems to solve the problem (waiting some days to see if this problem occurs again).
Is there any people who are experiencing some sim disapearring ? And how you managed to solve that issue ?
Thanks

I can't use wi-fi or sim card after flashing stock rom

My phone (china version with global rom) was bricked after I tried to install a global rom and lock the bootloader after that, in the middle of the process an error occurred, I got stuck in a bootloop with the recovery screen without bootloader, however I finally I was able to install the Chinese rom by edl, however no internet connection works, specifically wi-fi and SIM card, which prevents me from even unlocking the device with my account, I've tried hard reset, and recovery update but nothing changes
Attached some screenshots of the phone
