Can't get HTC HD2 working again!

Hi
Ok so my phone was working fine on a custom ROM when suddenly yesterday an exclamation appeared next to the phone signal and stopped from receiving/making calls and texts. I thought it had just crashed but after soft and hard resets and changing to a few others sims I just can't get my phone signal back.
Really strange as everything was working fine. I now have trouble flashing custom ROMs and am struggling to run a stock ROM because I'm on a mac.
It's driving me crazy as my phone is now useless.
Any ideas guys?
thanks

Quick update
I've managed to get the Leo Lite ROM running and everything is good except that damn exclamation mark next to the phone to phone, which means I can't get the phone working.
Anyone know know why this is???

Have you tried the sim in a different phone?
could just be a simple issue
And I know it a simple thing............but have you got flight mode on?

Thanks for the reply John.
Yeah currently having to use the sim in an ancient motorola and it works fine, tested with calls and texts. Also tried turning on and off flight mode but still that bloody exclamation mark stays.

That sounds like its been blocked. Theres a network there it just isn't letting it connect. Did you buy it second hand? or off ebay?

Hey Sam
Do you know what, I did buy it second hand, from a reputable store in town.
However this raises more questions than answers;
1. Why would it be blocked after several weeks of normal use.
2. Doesn't some sort of message need to be displayed stating the handset has been blocked.
Does anyone know if this is what happens when a HTC HD2 is blocked? i.e. the exclamation being shown all the time.
I presume a handset is blocked for security measures like theft. I will take it back to the shop tomorrow, they will have all the details of the person who sold it to them.
However is there no way this can happen from flashing custom ROMs? Even though that doesn't really make sense cause I had a ROM that was working fine and this happened when I was out and about.

It could be a bad rom, but it certainly wouldn't be in every rom.
I think id try going back to the stock rom, radio and spl (i.e an sd card flash, do you now if it has a provider locked rom?) and see if it is still there. If it still won't work, then it's definately either hardware or network.
The reason it could have taken weeks is, , seller trades in phone for cash, waits a little while, thinks 'i know'..., reports the phone lost/stolen to claim on insurance, insurance won't pay out without the imei being blocked.

Well I've tried flashing at least 6 custom ROMs, all show the exclamation mark.
The phone was sold to me as being unlocked to all networks, however I never tried with anything other than a o2 sim.
Now going back to the original ROM has its own problems. First off i'm quite new at this so sorry for sounding silly. How on earth do i go about finding out what the original stock rom, radio and spl is?
When I have these I can't easily go back as I don't have a pc, using a mac. I would have to use the sd card way but I can't find an official signed .nbh file.

I have a brand new T-Mo US HD2 with similar issue (out of the box). It's like the radio will not initialize. Did hard resets, tried to force it finding a carrier, etc, and it just will not turn on the radio.
I did find out that there is a likely issue with my SIM slot. If I attempt to remove my SIM card (which works fine in other phones) it is almost unremoveable and feels jammed in. However, once removed, I get connectivity via wifi and touch response is great.
If I insert a SIM card, it takes a LOT of pressure to reinsert it (yes, inserting it in the correct orientation), and the phone cannot connect turn on the phone's radio. Also, I get random phone.exe and credential.exe error message (plus the phone becomes very slow.
Don't know if you have any of these other symptoms, but the lack of connectivity sounds similar.
Supposed to get a replacement HD2 today, and we'll see.

I had the same problem too. I got unlocked code from tmoile and everything working fine for a month. It was working great after upgrade the latest rom 3.14 from tmobile download site (i got the message from them to upgrade), until i went out off country last month then the phone could not turn the phone's radio on. It kept at airplane mode. I been try to flash back and forth all the tmobile .50 stock rom and still having the problem.
Does any one know the issue to fix it? TIA

Looks like a hardware fault. You need to open case and check bottom two brass hinges are in working order and correctly hinged to make contact with antenna which is on the rear case at the bottom.
Follow the guide of opening s HD2 on YouTube there is a factory guide to dismantling the HD2.

Thanks for reply xlr8me. I just check the two brass hinges at the right side of usb connector. It looks fine to me. The other thing i didn't mention on the above post I was flash the dft_leo_nand android after tried all the stock rom from tmobile and the android said "no sim card", i also checked and cleaned the sim slot. Do you think any thing else to cause that problem?
One more thing without the sim or sd card the about phone show up all info of phone: imei, serial..... But with sim card in it just blank when i read the about phone hardware info. Thanks again

Did you try simcard from another carrier?

Yes I did tried the sim from the carrier of the asia country i was traveling to last month, that why i call tmobile to get the unlock code before i go. When i was there and inserted their carrier's sim and it won't work, even when i get back to U.S. I been tried either tmobile or at&t sim too. The phone radio won't turn on. The rest is working ok except those above error messages "A problem has occurred with device.exe" and "Credential.exe".
Do you think i can reflash with WWE rom .50 radio instead of tmobile's official rom?
Thanks

htcphonelover,
You will have to reset the phone back to default rom from htc website. You may also need to reformat sd card but the radio should still work regardless of whether the sd card is in or out.
My only concluding thoughts are that if the above fails to work then try a different sim card and still no good then probably something with the motherboard on HD2.
Good luck and update us with any new info..

Samsung Galaxy S II faults - any help appreciated

Hi all,
A few days ago I turned my Galaxy S II on to find the no signal line notification in the top right corner. Upon going to search for 'Mobile Networks' the phone is telling me to 'Insert SIM card to access network services' - I have tried my old and a new SIM card, both have given the same response.
I've tried factory and hard resets. Strangely, after the hard reset, my music (assumingly in USB stroage) is still there..?!
Even stranger is the phone's inability to show the IMEI - my provider has informed me that it hasn't been blocked, something I suppose.
The phone cannot connect to Kies however is recognised by my PC.
Any help/suggestions would be great, otherwise I may have to send it for repairs...
Thanks,

Guys I have a strange problem here...even though I am not charging my mobile it still shows charging symbol in the status bar. ...I restarted my mobile and I even flashed a different rom... nothing has worked...please guys help me out...

Restore your EFS backup. No backup ? A couple of options; search for threads on here about recovering IMEI and or/EFS. Lots of them with various things you can try in order to possibly fix the problem. If they don't work, you have two options.
One, service centre/authorised repairer. If you're lucky, they either won't notice or care you've been messing with the phone & they might fix it under warranty. Two, contact a member on here called Odia by PM and wait for him patiently to respond. If you hound him, he'll probably ignore you (quite reasonably too). He can sometimes recover IMEI/EFS for a small 'donation' which will probably be much cheaper than paying Samsung to fix it.
Edit - READ THIS FIRST: If you've never messed with the phone (rooted it or flashed non-stock firmware), then send it to Samsung in the first instance before you try and fix this yourself. If you haven't been mucking around with the phone, you shouldn't have any problem with warranty service. If you have, try the other suggestions.

Nexus 4 - No Service

Hi all,
I got a Nexus 4 from Ebay. Cellphone is in flawless condition, it probably has less than a couple of months of use. Unfortunately, I am not able to pick up a signal in any way. I just get a constant "No Service" message, and occasionally it will jump to "Emergency Calls Only".
Testing menu says Signal Strenght is 0 dBm 99 asu, no neighboring cells and location is unknown.
I've tried changing the prefered network to WCDMA only (as suggested in other threads), also tried with the other available settings with no luck. Tried playing around with the Change Bands setting as well but it makes no difference
Tried with a few different sim cards as well but that didn't work either, just got signal momentarily and but it would go on and off.
Cellphone came with 4.2.2 and I upgraded to 4.3 as requested by the system. Same issue.
Tried basebands 48 and 84.
Tried CM 10.2.
Replaced SIM card with a brand new one.
Cellphone doesn't appear to be blacklisted either.
Not sure what to do next. I'll try to get in contact with the seller but I don't expect much from him or eBay. Maybe I can sell off the device very cheap for spare parts, or send it for repair somewhere? Leave it as a dev device (which would virtually indistinguishable from a N5 that I plan to get anyway), Anyone else has any other suggestions or ideas?

Try to install a factory stock image: http://forum.xda-developers.com/showthread.php?t=2010312
If you pay with PayPal you get buyer protection so you can try to get your money back.
Could be a hardware or antenna issue.

To me it seems like its been blocked for certain reasons. Either it was reported stolen or the person who sold it to you didn't pay his/her bill for which the carrier blocked it. In that case you can't do much about it.
I would contact the seller right away. If you get no response contact paypal and eBay.

This problem is occurring for a lot of Nexus 4 users, including me. Its some sort of pandemic. Here’s what you can do to atleast restore service to your phone : flash the factory 4.3 image to your phone, again. However, try flashing a radio that is 54 or older with it. Make sure you wipe the cache and flash all the partitions, system, boot, bootloader and the old radio. This will bring back service to your phone (did for me), however you will be left with no in call audio and your phone wont connect to the internet through the mobile network, only wifi. After doing this, you will see your baseband and IMEI in the phone.
You can use this as some sort of “test” to verify if your phone really isn’t stolen. What is the ultimate resolution to this problem ? I really don’t know yet. I’ve been breaking my head over this for the past 4 days now. Maybe I’m going to try out the unbrick method mentioned over here to see if that helps.

As an update I am getting intermittent signal in some areas, but it's really spotty and only lasts a little while : (
I'll be giving different basebands a try tomorrow but I don't think it'll help much. I'll also try the full factory flash posted above.

Same problem here, had the phone for about 2-3 months, bought it off Kijiji, I tried flashing 4.2.2, went back to 4.3, flashed every baseband and still no success. The SIM works perfectly in another N4, tried a few other sim in mine and still the same results. Any other ways somebody got this fixed ?

I'm talking to the seller, see if the phone is still under warranty. My other options would be to change the antenna myself (see if it works), or resell it at loss for spare parts, or wait to see what eBay says.

Just to give you guys some hope, that this is not just a problem faced by second hand phones - My phone is bought directly from the Play store - I contacted Google service a few days back and they asked me to return the phone for a replacement. Only problem is I have to ship this back to the US (where I purchased from), since they dont provide replacement service outside the country of purchase. I'm in India now.
I've tried absolutely everything myself. Flashed many many radios, 4.3, 4.2.2, I'm only able to get it to the point where there is network coverage, I can make and receive calls but there is no in call audio, nor is there any mobile internet connectivity (Only through wifi).
Something tells me this is a problem with the latest OTA update that caused this issue - I was completely stock and everything was working properly, when this problem appeared one fine day - It started with me not able to connect to the mobile internet network for a few days, and then one fine morning, BAM. No service. It was only after this that I started flashing and re-installing stuff on my phone, desperately trying everything to get the phone back to normal again.
I think the last OTA update somehow "bricked" the radio (dont know if something like this is possible, just a noob guess). My only hope is the 4.4 update has some fix for this, else I'm going to try the unbrick method mentioned on these forums to see if that works. Only then will I take the pain to send this back to the US.

What's the unbrick method you are planning to follow?

I was considering using the unbrick method listed here : http://forum.xda-developers.com/showthread.php?t=2347060
Although I'm not completely sure it will work. Do you or anyone else have any suggestions for this ? I'm hoping 4.4 gets released ASAP, I'll download and root that as quickly as I can, hopefully Google has some resolution to this stupid problem

i have exactly the same problem
i have exactly the same problem. i bought my phone at US from Google play.
the phone worked fine for two month and then i got - No Service, and its swipe in a sec to emergency call only.
i try to replaced some sim cards, and factory reset with no success.
i also read a bug report that opened in Google : 58317
they told that there is a problem with the radio interface and radio driver at the 4.3 update, and they will fix it in 4.4 kitkat version.
i hope that 4.4 will fix this terrible problem, if not the phone is totally a door blocker..

Did anyone ever find a solution for this issue?
My friend has this problem with his Nexus 4.
I've searched A LOT and to this day (half a year later) haven't been able to find someone who reports this problem was solved.
I've also tried every suggestion I could find: flashed every stock image available, tried every combination of stock/custom ROM/recovery/radio, even tried the unbrick method mentioned above.
Nothing helps. I always get the same symptoms:
- Radios 54 and below - no in call audio.
- Radios 83 and above - Baseband unknown, IMEI / IMEI SV unknown, no cellular reception.
Also, RMA is not an option because the people at the store (a) don't know how to fix it and (b) claim the warranty doesn't cover this issue so they won't replace the device.
Any suggestions? I'm willing to try anything...

Maybe its a simple hardware failure like a loosely connected antenna? It doesn't really seem to be connected to any specific software setup
Something that happens to me rarely: when I'm in an area with very low/no reception sometimes the phone won't reconnect itself again and just stay on no reception until I reboot. Only happens like one or two times a month though.

Thanks, but I really don't think it could be an antenna issue.
I can see how a malfunctioning antenna could cause cellular reception problems, but it shouldn't affect IMEI or Baseband version readings. Those things have nothing to do with the antenna.
Also, the fact that the symptoms change with different radio firmwares says there's a big chance this is a software issue after all.
I just can't figure out what the cause is and how to eliminate it.

Flash any full factory image. If the problem persists after you can be pretty sure it's hardware. No signal for most of the time and occasionally picking it up could be something as simple as the antenna being unplugged, which can sometimes happen after a drop, or a forgetful repair.

Could be a broken or badly connected antenna. They are very fragile. Have a look at how to replace the antenna maybe?

I've opened up lots of my old phones (not my nexus 4 yet) and its normally easy to find and change as it's separate from the motherboard and looks basically like a piece of plastic!

I have the same problem no connection but the phone recognize the sim and the number of the phone. I've tryed to return to stock using a factory firmware but I'm not able to fix the problem... (this morning is working fine and my phone never fell down or something like that)
If I open btw the case and try to remove and reinsert correctly the antenna the phone will recognize the signal?

G935T no signal

Hi all,
I've got an SURE that was not working properly with with signal bars showing a small x. I thought it was because the devices imei was blacklisted, so I replaced the motherboard. It has the same problem, I tried T-mobile support to no avail. Finally I replaced the antenna assembly on the top of the phone thinking it was causing the problem. Nothing seems to work. The SIM card is able to be read and gives me the number that's registered to it.
Would flashing another ROM work to correct it. I've tried factory resets as well. Just wondering if anyone has any thoughts.
Thanks

SOLVED: OP6T no network (Coaxial connectors)

Its rare that i have an issue i cannot solve on my own, but this one has me stumped. last friday, i took the newest update on my OP6t 8/256 to 10.3.10 (unlocked, bought from OP directly). After the update, i lost cell service.and signal. i am bootloader unlocked, and eventually ended up using msm tool, which did not resolve my issues, despite wiping and relocking my device.
now, i am back on 10.3.10 and i only have some service when i am on wifi. i have cleared network settings and also manually added Tmob which errors out. i have tested the sim in my old Axon 7, and it works perfectly. also, the settings menu appears to show another update still, but it is not clickable. anyone have an idea? Thank you in advance for any help!

On that last screen where it shows your MAC address does your phone still have a IMEI ? (Don't post it, just it should have a number, yes or no?)

It still has both of them. (Dual sim). I have an axon 7 that lost it's EFS partition, so of course that was one of the first things I looked at. Having had that happen before, that was one of the first things I backed up when I got my fajita in 2018.

well, even a new sim card did not fix whatever has gone awry....
update: i took it apart, and pulled the shield over the board. tapped around. put sim in, it didnt work. rebooted with the sim still in and it worked almost all day. set it down on my desk, network disappeared again. pressed on the back just below and to the left of the camera hump, and it came back. worked for 5 min before stopping again. picked up a op9. but i will attempt to fix it later down the road. im guessing either the antennae is loose (checked all coax to ensure they were seated) or one of the multitude of drops, albeit in a good case, broke something beyond repair.

Update: after ordering a new sim reader and evaluating the phone some more, I realized the signal antennae was on the verge of breaking. Moving it with a nylon spudger finished the job.

Update 2, replaced snapped off gray coaxial and still had no network. Realized the other coaxial connector had popped loose and felt like it was seating, but it waant. So issue resolved not at all the software. It was the other coaxial connector. It felt like it was seating, but was not. Fixed and working well now. Woot. Thank you anyone who helped!!
