[Q] xt720 keeps rebooting when sim card n sdcard inserted - Milestone XT720 General

my milestone xt720 is 4 mths old.. my phone keeps on rebooting when the simcard n sdcard is inserted. It will restarts by itself after the M logo appears, and it will keep doing that until i removed the battery. I had reformatted the sdcard and use another simcard, but still the problem persist. The weird thing is, the phone works perfectly fine w/o sim and sd card. I have sent my phone to the service center and they said there is nothing wrong with the phone. Can anyone help me with this problem...

did you try reflashing the firmware? that most likely should do it. If not then I believe it would be a hardware problem =[

yar.. i did reflash it... but still to no avail... gonna pay the service center another visit this coming monday..

Did u try just using Sim Card w/o SD card and SD Card w/o Sim Card? to see which one might be the problem??

tried both. i have sent the phone for repairs. the lady from the service center said, its may be the motherboard that is giving the problems. they are changing the motherboard for me.

G2X won't recognize SIM card

Anyone else experience issues with swapping their SIM from their old phone into the G2X? I have reseated mine from my N1 into the phone 3 times, and each time I boot it says I have no SIM card. Pulling my hair out!
I went from an N1 to the g2x and i had the same problem so here is the deal...
the g2x is a 4g phone and it required a new sim card version so i had to trade in the sim card that i have had since my i got my razr in 2005...
so disclaimer to anyone who buys the phone outright, you have to have an updated sim card... just go into tmobile and they will give you one...
mines wont check for sim card at all it keep saying no service even without a sim card it usually say no sim but it just say no service can someone help plz plz plz
Fyi make sure it is a corporate store. Otherwise it could cost ya $20. Customer care might even be able to mail you one...not sure. If your near Chicago I would just give you one of my extras.

I reused the sim from my N1 and have had no issues but it was probably a newer version sim since I just got it beginning of last year.
If you have an old T-Mobile phone lying around, try inserting your SIM into that, and using it, then re-insert it into your G2X.
Alright I opened it up and it looked like the antenna cable was a bit frayed near the tip, I attached a few pics. It was connected though so not sure :/

I have the same issue.
Mint condition G2X does not detect my sim card reads "error while trying to connect to network"
I am running CM 7.2 I have wiped everything and reflashed still no luck.
Add one more to the pile...
I also recently began having this problem, but my device previously worked fine.
I have tried Restoring to Factory V21Y with Mar 11 Baseband
Flasing a GB Based ROM & Stock Kernel
Flashing CM9
Flashing CM10
Entering *#*#INFO#*#* Phone Info and modifying frequency band (No Go).
At one point I was able to read the Phone # from the SIM card, but couldn't get a lock on Netowkr. I can visually detect T-Mobile and ATT in Mobile Networks.
I have tried this with 4G Enabled SIM Cards and older T-Mobile SIM Cards.
I have tried Simple Mobile, Straight Talk, & ATT SIM Cards.
I have tried using None APN's, the TMo/Simple Default APN's, and Modified APN's for Straight Talk & Family Talk.
No avail.
Any ideas?
I had the same problem. A new SIM card fixed it.

I gave my friend my old G2x because she was switching from AT&T to TMobile. She went to the TMobile store and got a new SIM card and her old AT&T number transferred to it. It works on her old iPhone but when I insert the SIM card on the LG G2x , it keeps saying 'no SIM card inserted'....do i need to flash a certain baseband on it and/or setup a custom APN for it? I am on the stock ROM thats rooted...
Any help is much appreciateed
Sorry for not replying until now but I rarely visit here anymore. My G2X had a bad Sim card which a new Sim fixed. I just had to wait until the network could authorize with it.

[Q] Sim card not found

Alright, lately after I unlock my phone it tells me that my sim card is not found. It bugs me a lot because I have to shut the phone down and take the card out and back in. No, I didnt drop it and it isnt rooted. Is it my sim card or the phone? And if it keeps doing this, should I send it into ATT?
if you have some compressed air i'd blow it in the sim card slot, but thats probably not the problem i would take it to AT&T and try to get a new sim card or have them look at your phone
Is the sd/sim cover flush?

Is it the SD card that came with the phone, or one you bought separately?

I had to go get a new SIM card today because the original was not connecting. It initially didn't enable a network signal, so the gal rebooted my phone....and of course saw my custom boot animation and status icons and what not...I don't think she had seen a rooted phone before...said something about "you've really bling'd this thing out haven't you? This is the most customized phone I have ever seen"... [sheepish grin]
Pull out the batery and turn on with the sim card inside.

Try the battery pull mentioned above. If it keeps happening then try getting a new sim from att. If the issue persist then call att they will more then likely replace the phone.

Oops. I thought he said SD card. No wonder no one answered that question of mine. Lol

I have the same issue and tried everything . The sim works in others phones but not in the Huawei. And other Sims cards work on the huawei
Sent from my HUAWEI MT7-L09 using XDA Free mobile app
Has there been any luck? I am having the same issue however it worked the first time i put the sim in the phone but after that it no longer reads it and now every time i take it out there's multiple scratches on the sim card. I just bought it and was thinking about contacting Huawei about the warranty. Any thoughts?
You have probably managed somehow destroy the SIM card slot. I've noticed comparing to other phones that HAM7 SIM card slot is annoyingly tricky when putting your card in. It might have happened that the contacts have broken. I've read in some thread that there has been problems with it when putting card in. And no warranty applies here but it might depend on Huawei service.
I'm having the same problem with mine. I contacted Huawei and they actually answered me and said they were going to tell me where to send it in and that was the last I heard from them. Hell I'll pay to have it fixed just as long as it can be fixed.
Any luck? Was it the SIM card reader?
I think I have a similar problem, but I don't think I managed to damage the card reader.
Any help would be appreciated!

That problem is happening also with P8 Lite (phone from a friend of mine), SIM card is new, and no solution. Only reboot solves temporarily the problem
I am having a similar issue. I am overseas my phone is network unlocked. I brought a overseas SIM to get data. My phone does not recognise the new SIM. It still recognises the old SIM so I don't think there is a problem with the SIM reader. I have tried turning off and on and reboots etc. No luck. Really would like the data so that I can use google maps for navigating

[Q] No SIM card inserted?

So I tried CM12, and it did a lot of **** to my phone. I decided to go back to stock, and that worked fine, except I apparently have no SIM card inserted. I have never even opened the back of my LG G2 (AT&T) so I really don't know whats up with this or how to fix it. Can anyone help me?
I have a sim card, its worked in the past, but error messages now pop up whenever my phone boots saying I don't have one inserted.
