[Q] Please help! I may have ruined my phone

Hi all,
I've recently bought an HTC Legend from Virgin mobile, unlocked it, and now trying to get it to work on Rogers. After I unlocked it, I tested the phone by placing a call. It worked.
Then I got excited and decided to root it and load a custom ROM. I did not read the comments about the ROM and it turns out, the ROM changed my radio. When I go Network Operators on the phone it now says, "Your SIM card does not allow a connection to this network".
The ROM I used was Rodriguezstyle MoDaCoMoDrOm V2.3
I thought I lucked out and found the Bell RUU from Shipped ROMs but that didn't help at all.
I got too excited when I first received the phone and didn't take down the radio info before I starting messing about, which was stupid on my part.
I am freaking out a little and not sure what else to do. I had asked a friend to bring this phone over from Calgary, AB for me because they don't sell them in Winnipeg, MB where I live so bringing it back to the retail outlet is going to be pretty difficult.
Please, please, please help me. I apologize in advance if I am posting in the wrong spot.

You may be able to return for "warranty" purposes. Just lie through your teeth

Or you can do it the hard way. Just flash all the radio that was released. Try one by one and you might hit the spot. Try 7.08.35.21.

Haha! I wish I could. The retail outlet where the phone was purchased is in another province and is about a day's drive. They don't sell the device in the city I live in.
...although I could give it a shot here and ask them to ship one over? I'll save that as a last resort

I think I might have to try this method. Do you know if there is a repository of all the radio released for the Legend?

I've flashed the radio suggested, 7.08.35.21, still nothing. I was reading in another thread that it could be my SIM card? Strange how I was able to place a call when the phone was first unlocked. ...but it IS about 3 years old.
I'm not sure what else to do. I just may have to plead with the retail stores here. Hopefully they can ship me a new one

Whoops! I meant the SIM card. Sorry about the mix up.

I just got off the phone with Rogers Tech Support to see if there was anything wrong with my SIM. He said that the symptoms I am having seemed similar to that of a locked device ("Error while searching for networks" and "Your SIM card does not allow a connection to this network" when in Settings > Wireless & networks > Mobile network > Network Operators).
He mentioned that by flashing a new ROM, that could have re-locked the device. Sounds strange to me but if this is true, how do I find out which carrier the device is now locked to? I am now running the rooted ROM found at the root tutorial TheUnlockr.com.
The phone is not prompting me with an unlock code input like it did the first time around. Is there a way to bring up that prompt again?
Please and thanks

Hi all,
I hope everyone had a great holiday.
A few updates:
- tried flashing different ROMs
- tried toggling radio and autosync
- tried flashing a new radio
- tried using stock Bell Mobility RUU
- contacted Rogers and got them to reset me on the network
Still nothing, not even voice. I've been obsessing over this and it's driving me a little nuts.
rajasyaitan has suggested flashing all the radios that were released until I hit something that worked. Is there a repository out there?
I don't know why, but it never occurred to me to ask for the stock Virgin Mobile Canada RUU until now. Does anyone have it lying around somewhere or knows where I can get my hands on it? I can't find it online anywhere. If not, is there a way to pull it from a phone that is running the stock ROM? I'm not sure if it is the same as the Bell Mobility one but I thought I should start from the very beginning.
Any help will be greatly appreciated.
Thanks

Please my phone is having the same exact problem, it's not working! I'm with Virgin Mobile Canada and I cannot connect to my carrier telling me my SIM card is not allowing me to connect to them! Please someone help! I used this Rom called Stock Froyo ROM for the HTC Legend with Online Kitchen from Modaco.
And when I loaded it, it wouldn't let me access my settings and then I loaded my backed up Rom, and now I can't connect to my Mobile Carrier. (Virgin Mobile Canada) what should I do?

Just a thought here, but is it possible that the phone is SIM locked again? When you unlocked it, did you have to flash another radio FW? Did you try "unlocking" it again?

do you have the phone set to gsm only or something like that? should be set to wcdma only (for bell/virgin/telus)

Actually my phone is connected now, I had the same problem, I did something with the recovery before the problem was magically fixed, I went into recovery, and went down to "Backup/Restore" and I went to "Restore Google something sys..." (Restore NOT backup) and when it was done, my phone was working again, but I was on a different Rom other then the one that caused the trouble. That's what I did and it might have worked because of that I really don't know. And my phone is on "GSM/WCDMA auto", and it's connecting just fine.

SIM error

A few months ago I purchased two LG Optimus 7 E900 phones from Germany, on eBay. They were both Vodafone.de branded but that was easily removed after following easy-to-follow instructions on here.
I then signed up for two T-Mobile accounts for the phones and they have been working perfectly ever since. Sometime this week, both phones are showing a 'SIM error' and give the following message: The SIM card is missing or invalid. You can still make emergency calls if your mobile operator supports this.'
I have taken both SIM cards out and swapped them with other T-Mobile SIMS and I am getting the same message, although the SIMS from the phones work fine when popped into other phones! This morning, I phoned LG and they said that I should phone Vodafone and ask if they have locked the phones! As they were Vodafone.de (Germany) branded, I am not sure if they will have a clue or not.
Maybe I should go out and buy a Vodafone UK SIM and see if it works? But I assumed that if the phone was network-locked, it would ask for an unlock code?
Any ideas?
Mattresso

I just phoned LG and spoke to one of their support techs. He said that because they were bought from Germany and were Vodafone.de branded, there is nothing they can do. He advised me to send them back to Germany!! I told him that I was going to chuck them in the bin and he agreed. So much for customer service, eh??

Right, work this one out!
I decided to reflash the FW on the phone and get the thing working again. The LG Optimus 7 E900 original ROMS thread was followed to the letter and I successfully installed the Europe Open FW.
So, on completion, I slipped in the T-Mobile SIM card, only to be met with the SIM error message again!!!
Right, I am off to try the UK ROM and see if that works. If it doesn't I am off out to buy two iPhones!
Any ideas?

OK, now my head really hurts!
One of the phones has done a full reset and has the UK ROM installed and it works fine with the T-Mobile SIM installed. The only problem is that now it will not connect to any PC or Mac that I have.
The second phone has been reset and flashed with the same UK ROM. Unfortunately, this phone still shows the SIM error but it can connect to my PC and Mac!!!
Now, I have little/no knowledge of these matters but it seems to me that the problem/solution lies with the USB settings within the phone?
As part of the above instructions, it is suggested in post #78 that I should:
6. Go to Menu then 7.Engineering 3.Port 1.USB Switching Setting then select 2.QC Composite, change the driver for the USB, reboot the phone
Anyway, I followed this method (not sure if done on both phones) but I am not sure if anything needs reverting on completion of the flash.
Does anyone know?

It has to stay QC Composite!!
Going to try the SIM error phone again using the same FW and QC Composite selected!

Success at last!! Not sure why the hell it went tits-up to start with but I assume it must have been a wireless update from Vodafone.de?
Anyway, both phones working. Thanks for the help!!

I'm not sure we helped, but I've been intersetd in your story. Haven't had your issue myself, but I know a few others have.
So was flashing both phones what solved it?

Ensuring composite QC is selected, the SIM is removed and that the correct ROM is used are the three rules, it seems.
I'm convinced that it was a wireless update from a different carrier is what caused the problem. Anyway, it's sorted now, thankfully!
If you need any help, give me a shout and I will try my limited best.

Not really related to this post that I started but is it possible to connect my iPad to the phone (tether?) and connect to the web via mobile internet??

Of course you can - just update your Optimus 7 to the latest WP version via Zune, and enable Internet Sharing from the settings. This will make a WiFi network with a password for your iPad to connect to. Browse away

I had a problem like this too. Last night I plugged my phone into my PC to sync music through zune and was prompted to install an update. Installed the update and my phone works!
Running OS version: 7.10.7740.16 and finally have service!

same issue
I'm having the same issue. Phone is stuck at PUK code even though sim works in other phone. It is a UK Vodafone phone.
Can you give step by step guide of how you got yours to work?

Hmmm. Again, I am flummoxed!
My daughters' phones are both showing the SIM error message once again.
After previously flashing the phones with the UK open FW, the phones worked perfectly, until today! We all spent Christmas and New Year in Orlando and took the phones in the hope that a US sim would work in them. The sim didn't work in either phone and I resorted to buying a $20 Nokia! Worked fine too.
Anyway, on return to the UK today, the phones were powered up with the UK sims fitted but both phones are showing SIM error - No SIM.
I really am very, very close to throwing these phones in the trash! Anyone have any ideas why this has happened and will I need to re-flash them (again) in order to get them working??

I had this a short while after I was upgraded through Zune. I sent it into Vodafone and they fixed it, but it'll probably have to be the place you bought it from...

I bought the two of them from Germany via Ebay! They were both Vodafone.de branded but not locked but I re-flashed them with an open, UK firmware. Everything has been fine since the re-flashing, until now!
I have been in touch will LG and they said they will pick them up and repair if:
They are still in warranty
They have not been damaged due to dropping, etc.
They were purchased in the UK
All boxes are ticked apart from where they were bought. Surely a warranty must be valid anywhere within the EU?? Anyway, i am going to play dumb with LG and hope that they will reflash them....if not, I am definitely launching them into the sea! Damn fed up with them now and too much information on them has been lost too many times.

Almost certain mine wasn't within warrenty, they still did it for free. Mine happened very close to an update so I thought perhaps the update caused it. In that case they might say things along the lines of "you must meet certain conditions", but at the end of the day they'll quietly repair it free of charge. We'll see.

I sent both phones and received them both today with a letter titled, 'We've checked your handset and cannot find a fault'.
OK, so I immediately popped in my T-Mobile SIM and got the SIM Error message once again!!!
I'll phone them in the morning. If I get no joy, it's new phone time!

Sim error
I'm having the same problem after upgrading to 7.10.8107.79, try so many ways and still stuck with error. Can anyone help me, maybe telling me how to change FW, Rom Etc.
Here's what I have
OS Version: 7.10.8107.79
FW: 1.1.8.10
Hardware #: 1.0.0.0
Radio Software: 1.1.8.10
Radio Hardware: 0.3.5.0
Bootloader: 1.5.1.0
Thank you in advance
Update:
Problem detected, I just realized the connector pins on sim slot, one is broken not allowing full contact with the sIM card.

Hi, mattresso!
Thanks a lot for sharing the exprience which help me solve the "SIM error"!
I got my E900 from Hongkong last year, and the "SIM error" issued a few days ago. At first I tried to reflash the FW with Hongkong ROM, but it did not work. Then I found your thread and followed your way to install UK ROMs from Orange and Vodafone. Both of them make my E900 work well again.
Sorry for my poor English and thank you again.

[Q] Unlocked G2 wont connect to network?

I just recently bought an unlocked LG G2 and set up the phone on a Koodo plan. The phone has worked great up until a few days ago when I lost service and the phone wont connect to the network anymore, even after a factory reset. I brought the phone to Koodo and spoke with a guy that told me sometimes unlocked android phones have difficulty connecting to a network and that he didnt know how to help me. Ive tried manually entering network information and ive tried different koodo sim cards but nothing works. What should i do next?

Try another simcard provider
Try gsm only
Try to search fir network in network settings
Sent from my LG-D802 using XDA Premium 4 mobile app

Hi sricard,
I seem to be having the same issue as what you're experiencing. I have unlocked G2 that I'm using on Koodo network. Just last night my phone switched to emergency calls only. It was working perfectly fine for a whole month. And before that I was using the phone on Fido network with no issues.
Some additional info. I tried my friend's Roger's sim card on my phone and it showed emergency calls only. When my friend tried my sim, he was able to connect to Koodo network.
On my phone when I search for networks, it does find Koodo, Rogers, Bell networks. It just doesn't seem to be connecting for some reason.
My phone is stock, not rooted. I wasn't even doing anything out of the ordinary with my phone so I have not idea why this happened all of a sudden.
I tried the hard reset also and that didn't work for me either.
Not sure what else to do. May look into custom rom but not sure if that's going to work..

What I found out is that my phone had been blacklisted... which means that it had been reported lost or stolen by somebody else and the IMEI number had been reported. The phone became useless... and as one of the guys that i brought it to said, i essentially had a very expensive paperweight. hope your situation turns out better than mine!

I also have the same symptoms as this, checked the IMEI with Koodo on the phone. They don't see it on any of their lists.
I'm trying everything but can't fix it. Still trying.

Hi. I am in the same situation. Days ago i bought and unknow person Lg g2 d802. I think i have a solution for work back again our devices. Please contact to my email. [email protected] and i explain to you my idea.

Similar Problem
I have an lg vs980 and I was using it with H2O wireless and later I changed to Simple Mobile. I'm living in Puerto Rico. The phone was working all right and, suddenly, one day it was always displaying 'emergency calls only'.
I did factory reset, then I reflashed stock lollipop and it was like nothing happened, keeps displaying 'emergency calls only'.
Then I found this post http://forum.xda-developers.com/show....php?t=2394689 and applied the patch but didn't seem to resolve the problem.
As a last resort I tried flashing cm 12.1 and before first boot applied the patch from the cited thread but no result, keeps displaying 'emergency calls only'.
Has anyone found a solution to this problem?

Phone Not Allowed - UK SM-G950F

Hi All
I'm at my wits end with this Samsung S8 phone, Bought a 2nd hand S8, was working fine, but I noticed the internal storage was only showing 9.63GB
Had a look on here and the solution was to stock flash the phone. I did that, all fine, storage was back to normal....BUT since then I can't make or receive any calls.
I get the error "phone not allowed" and it won't connect to ANY mobile network.
I've tried loads of different suggestions
Sim is OK in another phone
Re Flashed (numerous times)
Andriod 7 and 8
Sim and Phone OK with three network
But still have the issue....
Can anyone help me? or push me in the right direction?
Cheers
Tommy

You probably tried this, but try booting into safe mode. If it works then there is a software problem. If the problems persist in safe mode you probably gotta contact Samsung.

Are you sure the phone is unlocked?

Is the phone blacklisted? if it is blacklisted then it will not connect to service. Your SIM wil work perfect in any other phone.

Hate to say this but it does sound like your phone has been blacklisted.
You can check with one of the online IMEI blacklists.

If your phone shows Phone not allowed and a code like MM#6, it usually is an indication that it was blacklisted.
Check your phone's IMEI on a blacklist checker like http://imeipro.info/

The previous user most likely had the firmware and baseband messed around with and once you flashed stock it reverted to true state, it's highly advised to get back in contact with the person, where was the phone bought? A shop? Online?

Yeah tried that , still the same

If one is in possesion of a S8 that says "Phone not allowed", and the phone is blacklisted, is there any way of fixing that?
I have the same issue here..
I bought an S8 from Manchester last summer, and I started using it last week, (because my other phone worked longer than expected) and after I gave the phone the Network key that the previous user wrote down for me, then that message appeared.
So im stuck with this almost completely new brick aswell...
Any options at all?

The only real solution here is to either go abroad and sell the phone, or sell it to someone who is going abroad. The phone will work outside of the UK.

It does sound as your phones imei Nr is blocked in UK.. Probably the person who sold you the phone, stole it somewhere.

I have the same problem on my Samsung S7 now in Brazil.
In Canada, on Canadian carriers, everything is fine, and if I put the Canadian SIM in there everything is fine. But the minute I plug in Brazilian SIM card, boom, Phone Not Allowed message comes up and it won't connect to any of the Brazilian networks. Brand new SIM, works just fine on another LG phone (and any other phone I tried).
The phone is unlocked, I even checked with a few pieces of software and there is no network lock on it either.
I've got the master & network unlock codes from Samsung, but have no way of inputting them as no prompts for those come up when I insert the Brazilian SIM.
I checked the IMEI, it is definitely clean and not blacklisted.
Heck, I even rooted the phone to see if that would help, and still nothing.
Any idea what else to try or what else might be causing this goddamn message to pop up?!

I solved my S8.
Blacklisted on all uk networks except Three network.
Works perfect.

S8 G950F wont get signal - not blacklisted IMEI: NG

hi all
i have a uk model s8 on the o2 network which was originally locked to o2.
so i took it the local market to get it unlocked which the market trader did and it accepted another uk sim
but wont connect to any network now. states emergency calls only, even with my original o2 sim.
i cant even search for any networks. when you try to search for networks by choosing the phone option, nothing happens, just states not available at this time. same thing when you try to choose manual or automatic search.
it accepts any sim now but wont connect to any network.
i thought it may have been barred even though i bought it 2nd hand and had it over 8 months so i checked imei on the net and it comes up clean. so not barred.
he couldnt also understand why you cannot search network, why this option cannot be selected.
so i come on this forum for some help, and a member did help me and got it working by flashing something to it via remote team viewer but after a few hours it stopped catching a signal because i downloaded an app onto it to hide root which worked but caused the phone to loose the signal again. and then when i contacted the member, he refused to do it again.
i pleaded with him to flash again or do whatever he did but after days of waiting without a phone he was not available to help. so please can anyone help and tell me what he did so i can fix my phone.
i know from users on here, you can have root hiding apps running on an s8 and still be able to perfom the fix to the problem on my phone.
i know it has something to do with imei not being registered on phone and it showing a NG next to imei.
any help or guidance would be appreciated
regards,
Margaret acey

don't O2 unlock phones for you free of charge? That is how it used to be when I was last in UK.
I really wouldn't trust anyone to remotely download/fix phone, they could do all sorts, hopefully you got a good guy but the fact they won't do it again seems suss to me.
Have you done this,
https://www.technobezz.com/fix-samsung-galaxymobile-network-available/
I suggest you flash stock o2 rom and take it to O2 to unlock phone, this will" clean" your phone so if the helpull member installed anything he shouldn't have it'll be wiped. Also check white o2 if your data etc has being used by someone else ie cloned your phone. (but there may be some other issue as the trader couldn't search for a network)

Thsnks for the response.
Its not locked anymore. As it accepts all sims which it didn't anymore.
This has something to do with the imei not been registered.
The imei status is NG when it should be OK.
