[Q] do i need the sim card to root + rom a phone? - Samsung Infuse 4G

basically the GF was super frustrated with her infuse....
constant loop reboots, gps radio awful, calls dropped, etc
so we tried to work with ATT - got new battery, got new phone
at this point she's fed up and put her sim card in her old blackberry
trying to help her out i'll put a different rom/kernel on the phone to see if it'll help -
but do i need her sim in there to do so? i can't imagine it is necessary but figure'd I'd ask before I brick it

Nope, you will be ok without it.

thank you very much

[Q] Problems with my Sidekick 4G, any ideas?

I've had this Sidekick for awhile worked great untill recently. I can get phone calls and texts for a little bit but no data, then its as if it just rejects the sim card. Then I'll get a (no service) where the t-mobile should be. I've tried many things Odin, root and install a new rom, mess with apn settings, new sim card. It seems as if nothing will fix this issues. If anyone has any suggestions please shoot away, untill then Im stuck with my old HD2.

[Q] Sim driver?

So i tried rooting my phone using debloated_deodexed_ep4d.tar.md5.
I took out the sim card during the process, even have a friends charge to test something from doing this before. I found out that some how after the flash the phones sim card slot stops working ive tried many other roms and modems to try getting it to work is anyone able to tell me why it would stop working does anyone have the working piece i need to get it to work again?
If you tried other roms, with the same result, then you need to get your phone exchanged.it isn't a dover issue if it happens with all roms.

Call verizon and get to second level of technical support. They can send something to your sim that displays "updating sim" on your screen.Not saying this will fix your issue but it worked for me on a similar situation. first thing tech guy asked was "you have 4g phone?" Than he sent the info.
Sent from my SCH-I510 using xda premium
i rooted my phone as soon as the first debloated rooted+voodoo came out and that installed fine but i liked having some of the features they got rid of and was a little buggy and ive tried two different debloated rooted roms they might be different but they seem to look the same and i cant do the sim update because i live in alaska where they have no "verizon" towers just leased towers or whatever from another cell leader in our area but suck for cell phone choices and only recently became price comparative. well i was hoping id get a programmer or someone that could help or someone who has an exact copy but i lost my job so i had to turn off my phone anyways better to stay local anyways. i just put my service on pause still have the unlimited package why i wanted to get root back on my phone

[Q] Help Needed

I have recently purchase a Note 4 clone phone from China. It works very well but I have a problem. When I got it I inserted an EE micro simcard which work fine whilst I waited for my proper talktalk simcard to arrive. Now however when I insert the talktalk simcard in I get no signal and the message emergency calls only.
I think with these types of the devices, once you insert the first sim card into it, they tend to lock onto that network and won't work with anyone other.
My question is therefore:-
Is there a way to unlock a Note 4 clone phone
If the phone can not be unlocked, I was thinking that if I back up the ROM and reflash the phone with the same ROM it might fix the problem. But I do not know how to back up the ROM. I've read a number of threads but still remain confused.
Any help would be greatly appreciated as I can not use the phone at all now. The device is rooted.
Thanks in advance
Any help guys

[Q] Can "SIM card not inserted" be a software issue or just hardware

Hey everyone!
I need some advice from an experienced member. More of a theoretical issue - can a phone not recognizing a SIM card be a software issue if the wifi is working?
I'm having some trouble with an old phone (S4 active ATT I537). I managed to flash it back to stock and played around with it for a few days, rooting, a ROM etc then restarted it one time and now it will not recognize the SIM card. It's driving me crazy I tried cleaning the contacts but I'm about to just sell it as is.
-Same SIM works in an S4 I337 right after I take it out of the active and put it in
-Wifi works on both phones
