htc hero unlocking

Hi, this is uploaded from my phone, so I'll be brief.
I bought an unlock code for my hero from, sigh, ebay.. and it (suprise suprise) doesn't work. I have contacted the seller and he says that I need to be running a stock rom (can remember off the top of my head). So, my question is - should I downgrade my villinrom3.3 with the latesr amon ra recovery image. And how hard will it be to get ir all back? I assume the rom he wants me to flash is quite new, so flashrec wont work ?
Thanks

I had the same problem. What I've done is: 1.nandroid backup 2. flashed sensehero 1.5 Rom (u don't lose recovery by flashing that) 3. Used my unlock code 4. Restored my nandroid backup. Done.

I'm not aware of any 2.1 ROM (Like Villain3.3 or BeHero 1.3.2) that will let you unlock, since they were all based on the Eris, which doesn't have a SIM.
So, flash SenseHero 1.5 and you should be fine. (as mentioned above)

I am restoring Kimera1.5, (backed up as I know 1.5 is quite important), should this work? Or will I need SenseHero?
Thanks for your help so far =D

Ok, just unlocked it... I have no signal though (emergancy calls only). I have heard I need to chage the settings somewhere, I have gone into Home>menu>settings>Wireless Controls>Mobile Network Settings>Network Operators> And then, no matter what I choose, "Your SIM card does not allow a connection to this network"... ??? I am currently trying to use a O2-UK SIM card, and you would have thought O2-UK is the most appropriate network provider to choose, this , however, doesn't work..
Thanks

Ok, just stuck a t-mobile sim in, and it seems to work. Is it just my O2 sim that is dodgey? It is just a free one that I have received in thepost - so it doesn't matter.
Do all (o2/vigin/tesco/orange/t-mobile/ect) work on the hero, or is it only t-mobile/orange?
Thanks again

Try to restore a backup first (2.1 will be good) if no success try different sim

All sims should work, I'm using 3UK.

Expiry date? The sim is like 2 years old So that's probably the problem.

issue solved

On a side note, Now that I am free, and now bound to any network; what network offers good:customer care, value fo rmoney, 1 month contract/payg, £10.
I am thinking of Virgin; unlimted texts, 200 mins... It is nice to have a data plan though...
Ideas? ALSO I just rang orange to tell them what a terrible service they offer and I am leaving unless they can offer virgin's deal.. They said they will ring me back
EDIT: Ok, they rang me back - and I can't haggle for any extra airtime/whatever... :L Looks like I'll be moving to Virgin.

If pay as you go data plan then 3. They got 1 month unlimited internet for fiver (2Gb fair usages policy)

Sounds pretty good, i used to be with 3 (ages ago) and i found thrm to be terrible.. Are they better now? Are they as good (value/customer care) as, say, o2?
Cheers.

Well, I'm with them for about a year now and I have no complaints. They have improved coverage a lot in last couple of years. Check their website for reference.

T-Mobile HTC G2 "Unable to connect to network"

EDIT: Just got off the phone with T-Mobile Tech Support, they tell me theres nothing more beyond a Factory Reset that could help the issue, and seeing as I've already done a factory reset a few times to no avail, I should look into getting my money back for this device.
Okay, so I purchased an HTC G2 from ebay. I know this was my first error in judgement, but I have a limited budget so i took what i could get.
Anyways, I currently have T-mobile on my Unlocked Iphone 3GS, but I've grown tired of Jailbreak problems and using 2G data speed.. So i Found this phone on Ebay, and purchased. when I got it, I quickly popped in my already active SIM card and got NO SERVICE, looked around on the phone and found the Network Settings, went to 'Network Operators' and searched for a network. T-Mobile and AT&T shows, but does not connect to either. when I inserted another T-Mobile SIM card, the same error shows. ( thought maybe my SIM was too old to receive 4g or some BS like that.. lol)
anyways, I dont need to Unlock my phone, I dont plan on using it on any other provider or in any other country. All i want is for it to work with T-Mobile, in america. is there anything I can do? or should I just send it back to the Ebay seller.
any information needed, let me know and I can get for you.. its running:
Android 2.3.4.
Baseband: 12.62.60.27U_26.13.04.19_M
Kernel: 2.6.35.10-g96de068
[email protected] #1
2.16.531.5 CL159515 release-keys

Is try a factory reset. Re insert sim. If still doesn't work call t mobile support. If still no go file an eBay complaint and send back broken phone for a refund.

Okay, thanks I'll try that right now.
Also, do you think T-Mobile will offer support to me, although i did not purchase the phone directly from them? They got testy with me a while back when I was having issues with the Dash.

Okay, so I just tried both Soft and Hard factory reset and neither worked. re-inserted SIM and still get either "this SIM is unsupported" or "Unable to connect to this network"
I also get an Alert on the Drop-down menu that shows " the network (T-Mobile) is Unavailable.

How old is your SIM? The G2 uses a newer SIM; go ask for a new SIM at your local store

Thanked you instead of quoting! Oh well, this was useful advice actually.
He is right - I had to get a new sim card when I got my g2 in order for it to function as a phone!

Oh, see then I suppose I wasnt wrong in thinking that then. so, If I go to a T-mobile and just get a newer SIM card, all should be well?

My SIM is about a year old, I also tried my sisters SIM which is a bit newer and receives 4G on her LG Optimus, I can still try to get a new SIM though, my question is if its free or not?

yes its free just tell them the sim is malfunctioning

Thanks, but after talking with T-Mobile tech support, we've found that my sim is up-to-date enough to receive 4g, and if its working in another phone then thats not the issue. it appears that the phone itself is malfunctioning in some way that prevents it from receiving any network. I've contacted the Seller and she's agreed to a refund. this is a real disappointment but its the only option left for me.
Unless anyone knows how to fix the problem of the G2 not accepting any network. After some research I've found this to be a common problem after an attempted Unlock of the device that went wrong. but, I've found no clear solution to it. Just alot of people complaining about it. I didnt attempt any unlock of this device, nor did I buy an Unlocked device purposefully.
the sad part is, I've only had the phone for two days, with NO SERVICE and i still love the device. IF i could find a more trustworthy dealer, without spending close to $100 more than I already spent, I'd love to use it.

Sim Card Removed - Restart/Reboot Phone

Hi there
i own a galaxy S3 TMobile version for 2 months now.
I recently update on last rom and since then i am getting the following error.
Sim card removed. Replace the sim with a valid sim and restart/reboot the phone.
I am not really sure if i wrote the message exactly as it appears but thats the meaning of it.
I have unlocked the phone to use it on Greece.
I have the same sim on it, since the beggining.
I didnt had the problem before the update. And for sure the problem poped up some days after the update.
When i see that msg the most of the times (if not always) data is enabled.
I should also say that when i see that msg the phone is just sitting untouched. Phone has never dropped or anything like that.
For sure its annoying.
When i restart phone sim is working perfectly...... ..
Has anyone heared about it? Anyone who faces the same prolem and found a solution?
I tried to google it ut i came up with no answers...
Any help is welcome.
Thank you in advance

have u tried a different SIM yet?
Sent from my SGH-T999 using xda premium

I had the same kind of issue on my previous phone. However, there is no data on my phone that I had to reboot my phone a few times to establish data connection. Secondly, sometime I missed called. Replacing SIM card may not help either. A few people had reported the same kind of issue on T-Mobile Support site.

I tthought I was the only one plagued by this issue..
I have this same issue. It usually happens whenever I lose network coverage......it happens repeatedly.. This issue started happening after I updated to jelly bean...ICS had no problems..
I have changed my sim 3 times, installed several touch wiz custom ROMs, changed my base bands and kernel...The issue remains prevalent after all these..
The only way I have been able to resolve this issue is by switching to an AOSP ROM like cm10 or paranoid android rom
I hope a fix for this issue is found soon cos i am tired of restarting my phone everytime i lose network coverage
I have attached a screenshot showing this

replacement sim ractified the problem

I had the same problem the other day when I was driving home from work. I think it happened when I went from 4G to 2G coverage. And also, when I'm in 2G coverage, signal fades out completely and comes back on 10 secs or so later. I went to Tmobile and replaced my sim with a new one and I had no problem of such ever since. .. at least so far so good.

Believe me I have Odin end back to stock n the issue still persists.....changing sim cards is only a temporary solution....
The problem always comes back especially if you always in an area with no network signal

Warranty exchange! Samsung should replace it. Say won't read sim card. Or tmobile

It seems that it happens when the data signal is bad.
Yesterday i had to reboot more than 3 times inside in a 4h period.
Wth........

First & foremost,
How did you "unlock" your phone? Did you mess with the NV data??
Or were you a good boy & had T-Mobile do it for you?
It sort of sounds like T-Mobile may have disabled your SIM card altogether....which may happen if you screwed around with the NV data.
If it was properly unlocked by T-Mobile you should be able to stick whatever SIM card in there now. Easy to test, go down the street to your nearest Greek mobile telecom store & ask if you can test a prepaid SIM card in your phone. Assuming the GSM networks are to some degree similar to the US T-Mobile networks, you should even be completely in good shape using local GSM service.
*IF* you get the same issues with the local SIM card....well screw it then. Go protest in the streets about the austerity measures in effect at the moment. Or just be a lazy Greek bastard & demand 14 months salary paid, require retirement at age 50 and lastly *NEVER* pay property tax on anything.

Well i have unlock the phone through internet. I had no issues for the past 2 months at all and yes i am using a local sim card from the beginning. The problem came up with the last upgrade!
Besides that i have a backup of the nv data but i am pretty sure that isnt the problem.

Foking politicians and goverments who have been stealing money for so many years. That was the problem and not the people!
I wish i knew why you mention all these!

sim card removed
I'm having the same issue with my s3
I tried to unlock it using this method
http://forum.xda-developers.com/showthread.php?t=2014982
I'm not sure if it worked, but perhaps messing with NV data screwed something up??
I upgraded to jelly bean 4.1.1
I tried cleaning the contacts on the sim
I replaced the sim at WIND
I even tried a factory reset
Nothing worked so far.
Has anyone figured out why it's doing this? Is it hardware related? software related?

In the same boat as you...I thought i was the only one..
on wind's sgh-t999v Galaxy SIII ... unlocked it like you did, and I'm getting a no sim card, restart required error, get it about every 8 hours or so..
i ported my number over too, but it says under "my phone number" in settings.. has a completely different number than what I'm currently using.. not sure if that has any effect..
tried restoring to factory settings too.. nothing seems to work...
if anyone has any info that would be much appreciated...

From the cold boot and after the error message goes away, does your phone has data connection?
I got the same error message on my previous phone. However, it would not establish the data connection.
Watch this video to see if your phone behaves the same way --> http://www.youtube.com/watch?v=GRB-cPD-JlE

mine doesn't do that, I have a data connection almost instantly where I have a signal
the error goes away after a reboot, but the error stalks you, and you never know when it's going to strike..
sometimes when it's in my pocket waiting for a call, while i'm driving with a headset on, at night while i'm asleep
for me, it isn't consistent, but it eventually happens..
I intend on taking it to the repair center for wind next week once I get back home (with the family for the holidays)

I don't think this issue has anything to do with if the NV data was messed with because my husband and I have the same phone purchased the same day 6 months ago. We both get the same error message and it's does not always happen at the same time so I am not sure it has anything to do with the network either. When it happens to him, he tells me it's happening but it does not happen to me. I googled the error because it is annoying. I will guess now that this issue has to do with the Gallaxy s3 and the update to the firmware. I can't wait for a better update.

Hi again
Since I know that there are a lot of people facing the same problem I thought it would be nice to give the solution on this kind of problem.
It seems that when you update via kies (of course on stock roms) something goes wrong. Recently I install the latest rom using odin and except that I found so many new things that I couldn't see before I also had no sim problem again.
So I am pretty sure that this kind of problem appears due to the kies updates. And from what I saw there where more.
If anyone else try the same please let me us know if it worked.
Good luck to u 2.
Btw yes I had that problem when the data signal was almost 0... Maybe 0.... Only then!

First of all I want to ensure you that has nothing to do with the way I unlocked the phone.
Second nv data is untouched.
3rd the problem came on after an update.
As I said after a clear fresh install without ba kups etc, starting from 0 the phone works great again and also there are options settings etc that I couldn't see before. Crazy but real. If anyone else do the same thing and make a fresh install with the latest rom he will agree with that.
So... As you said we make good parties and have nice womens... But how you will caption those moments those special (girls) moments without a nice camera (phone) ?
Have a good day hehe.

For those on the SGH-t999v version of the phone... the reason you are getting this "no sim error" is because of the firmware update to 4.1.1. I've sent my phone in for repairs and the best answer they could give to me was that there's an issue with the current jellybean.. not sure about the SGH-t999 standard versions though...
Unfortunately, I've had to revert back to ice cream ....and guess I have to wait till Lime Pie (OS 5) comes out...
The issue is not the NV data as I have used that method to unlock my phone as well.

Thank you for your replies. I'm relieved to know that it is not the nvdata menu that caused this problem.
I sent my phone in twice now and I've recieved it back for the second time today.
The first time resulted in further Sim card error messages. I'm keeping my fingers crossed in hopes that it does not appear again.
If op would be so kind to lead me to the right direction as to how to use Odin, I'd greatly appreciate it.

Unlocked GSM Galaxy Nexus - No signal al all

Hello,
A bit about my Nexus: Bought it online, it's the Domoco version, unlocked, rooted and been using just fine with many custom ROMs.
So yesterday morning, I was talking on the phone with a friend without any problem. After hanging up for a few hours, when I was about to call someone else, I realized my phone didn't have any signal at all. And it has been like that until now, about 48 hours.
It happened so suddenly without any warning. The phone has never been dropped and everything else working just fine.
So here's what I have tried:
- Restart the phone (multiple times)
- Batter pull (multiple times)
- Factory reset the phone (multiple times)
- Wipe cache and dalvik cache in CWM (multiple times)
- Downloaded SetCPU and set the minimum to 700Mhz (instead of 350Mhz)
- Reflash the ROM and tried with other Custom ROMs (I tried Xenon, Xylon, PA, and Carbon ROMs)
- Reflash the Radio and tried with other Radios too (I tried UILH1, XXLH1, SC04DOMLE3 and some others ...)
- I also went to Tmobile and request a new sim card - same problem.
- I borrowed a sim card from another Tmobile customer to try it on my phone - no signal - but the sim card works just fine on his phone.
I ran out of thing to try and I dont understand what happened ... anyone has an idea or something else for me to try ?
Anyone experience this before ?

Welcome too my hell. I have a playstore one now but my first Gnex was an international one and it has this same issue. Its a PCB problem a warranty would fix. I'm near Chicago and a few people have told me there is an electrical engineer downtown that fixes stuff like this. I don't have a price but I think something like this is your only option. Mine sadly is still a battery charger:thumbdown:

I know it sounds stupid, but have you tried toggling airplane mode? I run into the occasional loss of signal when im at work [fair to weak signal in the big metal box], and a reboot is the only thing that fixes it for me. Mines a play store model.

Ah yes, I actually did try that too but forgot to mention. I tried toggle airplane mode on and off, also the 2G only mode on and off. But it didn't help with anything.
Thanks for the suggestion.

So I guess I have to look for an electrician then, cause I have this phone just a little bit over a year so warranty is a no go for me.
Thanks for the idea.
PS: anyone else has more option for me ? I just wondered if I have bricked my phone ... cause I flashed lots of diff. ROMs to try out but never gotten a bricked phone before, could this be a bricked phone ?

Bricked refers to a phone that does what a brick does: nothing. It doesn't boot, it does not light or attempt to boot, it does nothing. This is a signal issue..I have no prior experience with docomo, but this thread came up on search: http://forum.xda-developers.com/showthread.php?t=1574018, maybe it'd be helpful. Have you converted it to yakju or takju and tried a google factory image?
And this: http://forum.xda-developers.com/showthread.php?t=1554150. If it is a circuit board, it kinda looks like s.o.l., and im sad to say that to you.

I wanted to let you know that I experienced the same issue. I bought the unlocked Docomo Galaxy Nexus, and had it working fine on T-Mobile for half a year, and then suddenly had no signal on Tuesday. Nothing I did - factory reset, battery in and out, sim card in and out - could fix it. Have you tried using different sim cards in your phone to see what works and what doesn't?
I figured out that my phone will accept AT&T, and actually does connect to T-Mobile while roaming (I used an international sim card). But, my phone will say "Cannot find mobile network" when any T-Mobile sim card is inserted.

I also have the same problem with the docomo phone. ATT Sim card works. Tried other's T-mobile sim cards and it doesn't work. I wonder if somehow the IMEI has been blocked by T-mobile.

I know others who bought their GNEX through the Play Store and those work just fine with T-mobile. I tried their sim cards in my phone and it doesn't work. I don't think T-mobile is intentionally blocking the docomo phones, because I'm getting T-mobile through roaming, when I use an international sim. My guess is they're doing something to the cell network that just somehow leaves our configuration out. Hopefully it's temporary, but who knows.
Worse case, I'll just purchase a Nexus 4, because I love 4G data for just $30/month with T-mobile. Anyone else got suggestions?

I also have the same problem with the docomo phone. ATT Sim card works. Tried other's T-mobile sim cards and it doesn't work. I wonder if somehow the IMEI has been blocked by T-mobile.

Alright, update on this and there' good news. I called Tmobile and they said my IMEI is actually Blocked. The reason, according to him, is that Tmobile usually sweep the network to clean up all "un-supported" devices, so my device is apparently one of them and therefore got blocked about 2 days ago.
So he said for this, he needs to escalate it to business support and they surely can unblock it for me, but I have to wait until Monday since they don't work on weekend. But well, that's surely a good news. phewwwwwwwwwwwwww !!!
So to all of you guys who are in the same situation, make sure you call Tmobile first before flashing crazy like I did LOL.
Thanks for all the help.

I'd love to know if you are able to get this unblocked and working as I have the same problem as of Tuesday. I was traveling and went into a TMO store, and they told me it was NOT IMEI blocked. In fact they looked at the IMEI and read the page and said 'it was not eligible for blocking'.

I called TMO to see if my phone is IMEI blocked, and through three levels of support the universal answer was no. I'm now fully confused because if it's a hardware issue, why did several people all have the same problem all on Tuesday. For those others who are having issues, can you see the TMO network but not connect to it? That's what I have, I can see TMO and AT&T but haven't been able to connect to either one since Tuesday.

I'll call up T-Mobile tomorrow and ask if they IMEI blocked my device. I had them reset my signal and give me a new SIM card, but didn't realize it could have been IMEI blocked. I'll give them a call on Monday and let you know what the result is. Maybe it won't be too late to cancel my order on that Nexus 4...

I'm quite confused. I've been told last Thursday in a TMO store and with tech support that I didn't have an IMEI block, and the same with three reps tonight. I know the Sim Card is good, and so I'm being told its a hardware issue. However, several of the same phones had the same issue on the same day, so I can't buy it's a hardware issue. Has anyone with this issue flashed a new or different radio into the phone, either before or after the service loss? I have not, running it as it came out of the box.

I just got off the phone with T-Mobile Support, and they told me the device is not blocked. The reason is that T-Mobile cannot block or unblock devices that are not registered to T-Mobile. So I'm back to square one on this.

chowabbajack - When did you first have a problem, last Tuesday? Did you prior to that do any flashing or radio changes to the phone?
We're in the same spot....

I did not do any kind of flashing or radio changes prior to Tuesday, when I lost signal.

That makes me think its something to do with the radio software, because I am the same the problem overall doesn't seem as large as the number of phones I perceive were bought on the Docomo deal.

Ive been using the docomo version of the nexus as well on tmobile for almost a year and it was since last tuesday when it no longer recieved any singal. with some digging around and too many phone calls, I found that the imei number on the phone is not the same as the one under the battery. i have the generic 004999010640000 imei right now and it not sure how i got it. as i bought it unlocked.
what i have tried:
reboot, battery plug, reinsert sim, factory reset, root and flash, got a new sim card, relocked, unlocked
sim card works on other phones.
also i have called tmobile and samsung endlessly and this is what i got:
tmobile cannot unblock the imei since it is not from them.
samsung is redirecting me to their japan branch.
docomo i cannot reach.
my phone before last tuesday:
unrooted stock 4.2.1
been testing different things to see if there is any way to restore the imei
also using root explorer, i cannot find my efs folder....

I've got the same problem since last Tuesday with my GNex and T-Mobile.
Mine is not from docomo though, but the French phone provider SFR, unlocked through FDocomo apk.
Rooted phone, running 4.2.1., no changes whatsoever in the past month and it worked fine until Tuesday, so I don't think I'm responsible for having no signal.
Honestly, I am relieved to see we are quite a few to have this problem, and also very pissed at T-Mobile for causing all this. What should be the next step then? Is there any chances they fix the issue quickly? If not, I might just go to the competition. I've tried AT&T sim cards and they work fine.

I have the exact same generic IMEI number as you, which does not match the number under the battery. I'm not liking the news that you did flash and still no go. I'm a novice at this stuff so please keep us posted.

AT&T sgh i747 will not read SIM cards

Hi I've been looking to xda for quite some time now for advice and help when I get stuck. First wanna say thank you! But I'm a new member so please correct me if I am posting in the wrong place or reposting. I'm aware that this is not a new problem, however, I have read till my eyes are bleeding and can't seem to find a fix. I have an sgh i747 AT&T gs3. I feel that this topic is unique in the fact that I have not rooted, flashed, altered or in any other way attempted to change this device. My fiance got the phone from her mom and I was going to try to use it with a straighttalk byop SIM kit. After activating the proper SIM with st the device would not recognize the SIM. I am now using that SIM in another phone. I get a constant ongoing notification in the notifications bar that says No SIM Insert SIM card. The device status is official and I have (as far as I know) stock ota updated 4.3 jellybean. When I insert a SIM into the device it doesn't prompt me to enter an unlock code. The only other SIM I tried to use is a sprint SIM card out of my freedompop lg volt. Don't know if that's compatible or not but I tried it and still the i747 acts as though it doesn't realize I've inserted a SIM. I called AT&T and emailed them. All I was able to give them was the imei as the phone number in my settings is unknown. The imei under my battery matches the imei in my device settings. They emailed me back within a few hours with my network unlock code and instructions for unlock. I haven't been able to use the code as my phone never prompts for the input of the code... I called them back later (this all happened earlier today) and spoke with a gentleman in tech support. I told him what was going on and asked him some questions. After doing a lot of research I started thinking that maybe my phone was already unlocked. Asked him to run the imei and said that it DID show unlocked on his end. That's one of my questions, if I still have an imei in my settings is this device still locked? The tech from AT&T told me it was probably the phone that was broke and I need a new SIM reader installed, to call Samsung. I tried to slide a little piece of paper in on top of the SIM that didn't work. I tried the dial code *#197328640# method, even though most posts say you must be 4.1.1 there are some who claim that it works on other versions. I tried a couple variations of this to no avail. I'm not sure what I'm overlooking here. If I'm leaving out any info that is needed to answer this post I'd be happy to include it just let me know. I need some fresh eyes on this thing it's driving me crazy I wanna get it fixed. I'm under the impression that I shouldn't attempt to downgrade this android version or I'll brick it... what the hecks goin on with this phone?! And again, sorry if I'm reposting but I can't find anyone who has posted yet that hasn't altered their device software in one way or another. I believe this s3 is completely official at this point. Thanks for any help you can offer

Is an sdcard recognized?
Was the phone ever used with a sim adapter? Sometimes, inserting and removing the sim adapter can damage the sim reader. Cheapest solution may be to purchase a new sim reader from eBay.

Sdcard works fine... and I'm pretty sure it's never been used with a SIM adapter

It's possible the sim reader has failed. Don't think you'll kn for sure until you are change the sim reader.

Yeeeah... I think I'm gonna attempt to change it right now and see what happens. I'll post back with the results. Thanks guys!

Fixed! Replaced sim port with spare one from an s3 sch I535 I had laying in the junk drawer with a broken LCD display. Posting this from my i747 on straight talk 4g. Sweet!

Glad it worked for you.

Yes and thank you again for responding to my post. This s3 is now rooted and titanium backed! Now excited to attempt to flash cyanogen mod later this evening. Thanks again and take care!
