[HTC One X+] ICEMAN_77:
Hi all,

I am newbie and no developer. I have just severe trouble with my beloved phone.

About 1 month ago it started that way, that the mobile data and cell connection was sometimes there and sometimes not.

One day later it was 95% not able to do calls. Sometimes after rebooting it worked again.

The OS at that time was 4.2.2, stock version.

I found that I have that stuck in airplane mode error. The device says that it is momentarily in shutting off airplane mode, but never gets out ouf that state. Symptoms are also no IMEI in OS available and SIM access seems not to be there

I thought about GSM antenna probs and found some damaged spring contacts and changed that pcb. Also renewed the coax connection cable

from MoBo to GSM antenna pcb. But this didn´t help at all.

After that I worked on changing to Cyanogenmod, as a remedy : post-build=htc_europe/enrc2b/enrc2b:4.3/JRO03C/125529.22:user/release-keys

post-timestamp=1385502720 pre-device=enrc2b

I unlocked it. Put TWRP on it and did S-OFF. Then I flashed the boot.img and then I flashed the ROM and erased cache. Most of the work by direct adb commands, since the toolkit made more problems than solutions.

The result is as that of many other users, the problem is still there. Did also try with emergency calls, it says there is no network in my area.

But with CM it works faster and makes really fun. If only that GSM functionality was there. Wifi and bluetooth and that other crap all works.

After reboot it usually says, that flightmode is on at the moment.

and C:\android>fastboot getvar all says:

all: Done!

finished. total time: 0.438s

so the IMEI is available but not to the OS

It can be, that I did not perfect at flashing boot.img and ROM and doing S-OFF a.s.o. in the best order.

Are there any ideas, how to find out more?

Can catlog help in any way? What other debugging options could help?

Is the missing SIM access a possible root cause, or is it consequence of something else like damaged radio or .... ?

Are there tools, to kick the airplane mode completely off or would this just be a stupid idea?

Could older radio versions help?

Initially, the problem came not through fumbling with ROMs a.s.o. What was the cause at that time?

I read really a lot of topics from very different forums (US and Europe). But it seems still that a few people find solutions (the solutions are different and don´t point to the root cause imho) and a lot of people don´t find a solution.

I would be really happy if there were some answers or ideas.

Best Regards,

ICE
