[Q] htc hd2 ROM code error

hi
i tried to restore original OS into my mobile through sd card and it went faild i got an error "upgrade ROM code erre please try again" and i can't fix it now i have tried almost everything but all in vain ! and few months ago i lost its original charger and data cable so my pc can't detect the new data cable i have only way to go through the process is sd card plz help me out of this if anybody knows
you probably used the wrong stock rom. flashing any old stock rom from sd card first removes hspl, then tries to flash the rom, but since hspl has gone, only the correct carrier/region rom will work.
Alternatively, if the flash failed part way through and you get rom code error, you can usually just go ahead and try the flash again.
to help further you need to provide more info (should have been in post 1) model of hd2, exact filename for rom you tried to flash, what you know about the phone like where it was bought from ((i.e was it carrier branded)),

[Q] Help - No sim card error

Hello,
i have got a S4 which has been rooted and flashed. It worked fine for a while but now every now and then i get a error message saying there is no sim card in it. When i reboot the phone it works normal again, without touching the sim or opening it.
I have cleaned sim card and contacts but that did not help.
Any ideas what else to try?
TIA

Hi ,
SIM card problems if they are not hardware related , they are usually caused by IMEI ( efs folder) or wrong modem if you have and efs folder backup , restore it.
What S4 you have , what rom do you have , what modem do you have??
When it fails to recognize the sim card check your IMEI dial *#06#
Hello,
i have tried everything i can think of without any success. It is a Samsung Gt-I9505.
The problem with checking IMEI when it does not recognize the SIM card is that i can't do anything but restart it. There is a error message with restart as the only option.
Now it is doing it as soon as it starts up. I never have to remove the SIM card so the phone recognizes it, just a simple restart without touching the SIM is enough.
I am on the last official Australian ROM. Baseband I9505XXUGNH6, Hernel 3.4.0-2309103 Build number KOT49H.I9505XXUGNH6
I have tried it with another SIM and same thing happens so it is not because of the SIM card.
Any ideas what else to try? I do not have any back ups of anything.

Hi mate,
Your case is not clear , it does not look like firmware but i would not discard that possibility , do you have stock or custom rom? try to reflash
Also there is a chance for what you tell me that the sim caddy may be defective

I am on official ROM, flashed over ODIN. You recommended to check the IMEI when this happens but i can't because the only option is to restart the phone.

Please more details
When you have the no sim errors it does not allow you to dial *#06# ? why does the phone freeze ?

No, it does not freeze but a pop up shows with only one option "restart". I tried to touch the screen, home or return button but nothing works but touching the restart button.

I see, is strange if you said that whith a reboot works fine it make me think more in a hardware issue...maybe the sim caddy..
This phone is driving me crazy. The replacement SIM reader arrived today and i replaced it. Now it does not find any SIM, just getting NO SIM error as soon as it starts up. I tried putting back in the old reader but the same happens.
Anyone any idea what to do or just recycle the damn phone?
Come on guys there must be someone with an idea

[SM-G530M] SIM Locked after Firmware update

Hello, friends.
I do need your help.
I wanted to tell you that I had some problems with my phone's performance, so, after almost a year, I decided to upate its firmware.
* I've to mention that my SM-G530M was already SIM unlocked from seller/provider (Movistar Colombia).
* Also, all this time I've been using a SIM from Claro Argentina without any problem on that device.
I installed this firmware, using Odin (most of all, because I live now in Argentina):
--> G530MUBS1APE4_UUB1AOI1_ARO_Argentina_4.4.4.zip
When the process ended, it booted up normally, but after a reboot it started to ask me to put SIM network code.
* I've tried to flash different firmwares (Colombia, Argentina, Chile, etc.). With/without SIM card inserted.
* Also I've tried Factory Reset and Wipe cache (from software and recovery too).
* I even have tried to use "NAND erase all" in Odin, all in order to clean the most from the device to get prepared for a clean Firmware installation.
Unfortunately nothing worked.
I'm in ruins.
Please, friends, is there anyone who could guide me in order to unlock my phone again?
If you need more info, just tell me.
Thanks in advance!:
I know it's too old to reply, but at least I'll report that problem is solved forcefully, bands to other carriers had to be reopened. Unfortunately I don't know if the culprit of this SIM locking was the Claro's provider ROM I used, taking in mind it is the one I use in Argentina, but device was from another country. However this wasn't a case of international carrier restriction, since device was already unlocked, but this update broke it all.

SIM 1 Slot is not Detecting

Previously i have rooted my mobile and it was working fine. I tried to install new software update, So i flashed the stock firmware i lost my wifi and network connectivity (both sim cards were not detecting). I flashed again stock firmware which was suggested by some senior member in XDA. After flashing that firmware i got my wifi and mobile network but my SIM 1 SLOT is not detecting. Tried to wipe data and flashed another stock firmware still the same issue occurs. I tried swapping sim cards but it is not detecting in SIM 1 slot which is detecting in SIM 2 slot.
Found that IMEI is there.
Is this software issue or hardware issue?
Please give any solution.

DO you have the global or the EAA version? If you have the global version you can try to flash full package of 1.1.4 to solve the issue.

How did you do the full flash? There is a tutorial in here where 1 command is false i think.
its flash fastboot xbl xbl.img but it should be fastboot flash xbl xbl.img.
Maybe thats what you need to repair but i think xbl image is about ram....

My imei is normal no problems
Maybe I can help with a solution: I have 2 SIMs and my mobile data suddenly stopped working one day. (It seems because the mobile carrier had technical issues in my area.) Now as I use mobile data only on SIM1 which I de-activated during the day in hope to get a connection back, I assume my preferred SIM changed (see Settings -> Network & Internet -> SIM Cards: Standard SIMs) to SIM2 for calls and mobile data. As the phone tried SIM2 for data but it is de-activeted there, both networks had a small "!" near the radio indicator. After settings the preferred SIM back to SIM1, everything is working fine again.

The problem is that the cell phone doesn't recognize any chip, so I can't open the sim card options
Hello i have also updated to 1.1.4 and after around a month it is also not recognizing my sim card. The sim card works on any other phone. I have tried rebooting, soft restarting, resetting all network options, I even changed the sim at the store. Nothing has fixed my issue. My last resort is factory reset.
Has anyone found a solution?
