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..

Nexus 4 - SIM problem

Hello,
I just got a Nexus 4 16GB (had a 8GB before) and I've to reenter my PIN code almost every time I'm unlocking the phone when it has been in deep sleep. (the card is locked and the phone is disconnected from the network)
I first thought it's caused by custom ROMs, but it's even happening on stock ROM/kernel...
Am I the only one with that kind of problem ?

If you get the sim pin wrong a couple of times, the card is locked and you need to call your provider for a personal unlock code.
If you keep trying to unlock it eventually the sim will simply become inoperable and you'll need a new one.

I can unlock it without a problem after entering my correct pin.
So it is not a problem with the SIM or my provider.

Go into Settings > security and then there should be an option along the lines of Sim card lock. Try checking in there.
Sent from my GT-I9100 using xda premium

Disabled the pin lock for now.. But the signal still drops when the phone is longer in deep sleep.

I had the same problem!
I don't know if this is rom or kernel related, but since I switched to ParanoidAndroid it's gone....

Ah finally someone with the same problem.
I've already been running PA, but the problem did still exist.
Did you change anything else beside that?

i removed my SIM again and cleaned it.

i've also had that issue the second day after receiving the phone. I removed the sim, put it back in but that didn't help - i looked at my sim card tray and i realized that a one side of the sim card chip was close to one metal side of the tray and i figured that could be the issue - so what i did is i took a stripe of adhesive tape and made sure they wouldn't touch - I haven't had the issue again and it's been more than 2 weeks.

Uh...I remember a kernel arg from my old HTC Topaz WiMo-Device, which was able to run XDAndroid.
The argument was pm.sleep_mode, and it is still available on the Nexus 4 and set in the system/build.prop
It controls, how the device handles locking, usually it is set to 1, but, i think, it goes from 5 to 0, where 5 is "stay on all the time" and 0 is "shut down everything when locked".
You could try to swich it to 2 or 3, maybe it helps.

I got a replacement phone which is working fine now.
Thanks for the tips anyway

hmm got a 16gb one and the Sim keeps disconnecting even without deep sleep.
might need to send it back too. poop

Hi,
I got the same problem too.
Sometime, it's getting worse and worse so I have no other choice but to reboot the phone --> When I put my PIN code and press the validation button, the screen doesn't go to the main menu but asks me again about my PIN code. Infinite loop...
I cleaned the SIM card 15min ago and no problem since (fingers crossed). I read an alternative version of android solved the issue in one case but not always. I won't take that risk if I have to send it back to the manufacturer. Before I do that, could you suggest me something else to try ?
Many thanks for your help.
Best,
Valentin

I had the Nexus 4 since December and yesterday for the first time the phone asked for the PIN code and lost the connection to the network. And like posytryon I had to enter the PIN more than once (in my case it was "only" twice). This morning it already happened twice again. Never rooted the phone, stock Android on it. What is going on?

Why are you people so paranoid? I've never used a lock on mine. In all these years....
Just asking for trouble using sim lock IMO.

What kind of silly reply is that? Why is it asking for trouble using SIM lock??? And if you read through this thread, someone had the same problem of the phone not connecting anymore even without SIM lock.

I pulled my sim yesterday because I switched users now it says no sim I put old sim in same problem flashed new rom nothing...

I'd noticed the same thing, and insulating the SIM from the holder resolved the problem for me also.
I also found an app for monitoring and alerting if the phone switched back to asking for the SIM PIN, this might be useful for others.
SIM Locked Notifier - https://play.google.com/store/apps/details?id=org.slaytanic.SIMLockedRingNotifier

Finally put some adhesive between the tray and the SIM card. Worked perfectly for me too, no SIM problem for 10 days now.
Thank you so much, Lucker#1.

SM-N910F "No Sim Inserted" Issues

As the title suggests, my phone is coming up with "No SIM Inserted" warnings, and forces me to restart two or three times to get the problem to go away. This happens pretty much daily, at the minimum.
Restarting takes an annoying amount of battery and time, so it's a bit of a pain. The SIM eventually works, but it's not a good sign.
Since the card eventually works, I'd imagine that this is some sort of Firmware issue? My internet is horrible, so downloading it from sammobile would take forever. So I thought that I'd come get your guys opinion on it first on whether it's a hardware issue, or a software issue.. I've noticed a lot of other phones (such as the S4) having this issue, and I'm wondering if anyone has had any experience on fixing it?
It's unrooted so it's still under warranty.
Cheers,
Zaslamel42

First thing I would try is clean the sim card then factory reset with the sim inserted. I had to do this with mine (once) but thought it was just a glitch so never posted about it. After that I'd try another sim to test the handset or replace the sim card if it was the same.

Had this problem in one of my older phones, can't remember which.
At some point your SIM will stop working altogether and reboots just won't fix it anymore.
I contacted my provider and asked for a new SIM and that solved my problem.
I think it's worth getting a new SIM, or at least trying with a different one.

I'm not sure how I'd clean it, exactly. So I just sorta blew on it, and the tray. If it happens again I'll probably just get a new SIMcard.

The SIM is barely a year old, so it's a bit of a pain if I'll have to get a new one. However, it'd cost me nothing to get a new one, anyway.
Thanks a lot for your input. It only started happening about a week or two ago, so it probably is the SIM.

When I had that issue, it was with a few days old SIM, sometimes they're just defective. I know what you mean about the hassle though.

Clean the SIM with a pencil eraser.

Axon 7 A2017g b04 Cellular Radio off ???????

Hello,
I just got the Axon on amazon, a 2nd hand one.
I inserted my sim card and there is no way to have the cellular radio on. I did an full wipe twice, swapped sim, inserted a new one... nothing. Signal strength is zero. I tried also to do an emergency phone call (it should work even without the simcard) nothing. It says that I'm in aeroplane mode. But it's not. I did a manual search of the network, it says error while searching for networks... If I select choose automatically it says registered on the network (but it's not!).
I installed LTE discovery and it says that radio is off... I've tried to reset data connection... nothing...
any thoughts ?
I will send the phone back to the seller but if it's just a software glitch I would rather keep it ....

-Look on the back of the phone, below the Dolby Atmos and "do not dispose of" symbols, and tell me what is the model of the phone. It may be an A2017, and if that's the case maybe they installed the wrong modem and erased the IMEIs
-Try putting your SIM on the 2nd slot
-Try finding the phone's IMEI from the system, maybe it is under About phone - Signal status or sth like that.
-Try another SIM
Those are my ideas for the time being. I also remember there was a secret code that you can put on the phone app, it opens a settings app with a bunch of tweaks and you might be able to change something. Just google "axon 7 secret codes" or similar

Send it back... almost 100% not a software issue

Mine stopped working out of nowhere, the radio that is. I sent it back in and they send me a new one, no questions asked. Although the replacement they sent me may have been refurbished and I set the phone down and picked it back up and the screen was unresponsive after. It turned on but I think the digitizer got unplugged or something because I couldnt do anything on the screen. Yay for mid-range phones?

I've read that you can fix that by applying pressure on the screen, like in the center, then going to the sides or something like that...
The digitizer is the same plug as the screen though, so it didn't get disconnected

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!!
