[Galaxy S II Q&A, Help & Troubleshooting] E:V:A:
It is still not clear what you do. Do you type this in the same terminal as before?

If that is so, then what I think is happening is that when you stop the RIL daemon in the proper way, as you do above, it resets the modem AT interface to default values. Which means displaying something different when ringing, if anything... You can probably confirm if this is true by instead trying:

kill -9 `pidof rild`

This kills the process in its shoes and should leave the modem as you find it in the first steps.
[Galaxy S II Q&A, Help & Troubleshooting] brok85:
yes I always use the same terminal...

I am gonna give it a shot and I will update :)

Actually it seems that after executing

kill -9 `pidof rild`

rild just restarts automatically :( It does not stay off...any suggestion?
[Galaxy S II Q&A, Help & Troubleshooting] brok85:
actually I think that after I stop RILD, something changes in the modem settings. Indeed, when RILD is active and I am receiving a call, the message "RING" is sent from the modem. However, after turning off RILD, the message "RING" is not sent anymore, even though the caller information are still sent through the "+CLIP" command (e.g., +CLIP,phone_number,129,,,,,).

Is it possible that ATA works only if the command RING is being sent from the modem? maybe that is why I receive "NO CARRIER" after issuing ATA when RILD is stopped (while receiving a voice-call obviously...).

How can I enable the message RING to be sent even when RILD is not active?

thanks a lot for any help!!!!

[MENTION=5802519]brok85[/MENTION] You need to read the thread! If you had done so you would have found that you can enable "verbose" unsolicited AT comamnds. Try with these:

ATV1 - enable verbose response text
ATE1 - enable echo
AT+CEER
AT+CMEE

...and so on.

[Galaxy S II Q&A, Help & Troubleshooting] CVAngelo:
Simple question or maybe not: I have a dual SIM phone. In MTK Engineering, the SIM1 radio is ON and the SIM2 radio is OFF. The result is that when the phone is turned on, it appears as though there is only one SIM slot. Only one signal shows up. I can only use one sim card in the phone. Placing a sim card in the second slot is useless because the sim2 slot itself is effectively deactivated.

How can I turn the SIM2 radio back ON so that the phone "sees" two sims instead of just SIM1? What tool do I need to use here?
[Galaxy S II Q&A, Help & Troubleshooting] CVAngelo:
Only solution I have found to this problem is to flash the phone with a ROM from the identical phone that has the SIM2 radio on. Seems a bit extreme! Is there no simple way to turn a freaking radio on??

Hi has anyone found a way to either open settings in the same way that atd(n);\r\n opens and initiates a call? Or better yet found a command that allows enabling of developer mode and then usb debugging? I only saw one entry (so far just skimmed through the lists in this post) that relates to debug but it didn't look like it was in relation to the developer options debugging that I am referring to.
[Galaxy S II Q&A, Help & Troubleshooting] CVAngelo:
What does developer mode and USB debugging have to do with the modem and thus with modem commands? How could such a modem command exist?

[Galaxy S II Q&A, Help & Troubleshooting] Sollace:
Hi, I have a Sony Xperia ZX that I've been trying to communicate with the modem.

I've been able to identify a port at /dev/tty but when I use the command:

busybox microcom -t 500000000 /dev/tty

The connection is successful, but I don't get any response to my AT commands exactly as described in the main post.

Where is this "later post" that is supposed to deal with this issue?

Edit:

After a little more investigating:

cd /dev/
ls | grep tty

I was able to identify another port (/dev/ttyHS0) that seems to be providing some output.

Still no response to my AT commands when sent to it, though.

Logcat shows it's being opened and written to, and catting the file produces a lot of binary output, so something is definitely listening on it.

logcat | grep /dev/

I'm having the exact problem with ttyHS0. How did you get the output working?
[Galaxy S II Q&A, Help & Troubleshooting] Sollace:
Hi hi! Wow, it's been a hot minute. I almost forgot I even had this account.

Anyway, try using /dev/smd7 or /dev/smd8 for executing AT commands. Seems those are the correct places to look for the Sony XZs, not any of the tty* files.

My experience with busybox has also been... less than stellar. So the full solution I landed on was:

echo -e 'AT \r' > /dev/smd7

or

echo -e 'AT \r' > /dev/smd8

to execute, and a simple cat to read. Replace "AT" with whatever command you need from the reference pages.
[Galaxy S II Q&A, Help & Troubleshooting] Publii:
Thank you so much for responding. I got it working. I was using microcom instead of cat and it was the problem. smd7 also worked for me.

[Atrix 4G Q&A, Help & Troubleshooting] T4CT:
I've tried searching a bunch (both here and general google) but finding information on purposely frying a phone is really hard. If I've somehow missed something already written, please point me in the right direction.

I own an Atrix in Canada locked to Bell. I need to find a way to brick this phone, fry the power in it, etc...something that'll essentially make it so that the phone permanently doesn't turn on.

For background, I work at Future Shop (for those in the states, it's a subsidiary of best buy) and have the Exchange Plan on my phone since employees are strongly encouraged to get it. I'm going to get the phone swapped, but the LCD under the screen is cracked. The screen itself is fine, so there's no sign of physical damage, but I need the phone to be unable to turn on just in case the store I return it to deems that as not covered (they shouldn't, LCD screens are technically covered, but better safe than sorry).

Help me break my phone!

[Epic 4G Q&A, Help & Troubleshooting] gooch1025:
So I know what a nandroid backup does but I was hoping you guys can help me understand a couple of things better. After you create one, is it always there or just until you restore it? Also, can you backup multiple nandroid backups, and when you're done with one, how do you delete it?
[Epic 4G Q&A, Help & Troubleshooting] flastnoles11:
Yes they are always there... they go to the clockworkmod folder on the sd card... and you can deete them from there if no longer needed.. you can nandroid a rom as many times as you want... I have about 5 different roms backed up right now that I can jump to anytime I want...
[Epic 4G Q&A, Help & Troubleshooting] gooch1025:
Awesome thank you for explaining. One more question. Do you always wipe data and caches before restoring or does the nandroid restore do it for you?
[Epic 4G Q&A, Help & Troubleshooting] flastnoles11:
I have never wiped anything when restoring a nandroid and bever had problems... pretty sure the restore process wipes everything for you...
[Epic 4G Q&A, Help & Troubleshooting] Tomcat5:
Since we're all here about Nandroids should they take >30 minutes to do? My Epic always hangs on .android_secure for a huge amount of time before it actually starts backing stuff up or restoring it. That's why I don't do them, in the time it takes to make a backup I can already be restoring my stuff.
[Epic 4G Q&A, Help & Troubleshooting] ÜBER™:
That's abnormal that usually takes a good amount of time but I just backed up a 400mb miui and it took around 4-5 minutes and about 8 minutes to restore my 500mb cm7 ;)

You are using CWM 5.0.2.7 right? Because that has a better backup and restore method that takes about half the time of it's predecessors.
[Epic 4G Q&A, Help & Troubleshooting] TexasAggie97:
Sorry for the newbie question, but how does one perform a "nandroid backup" on their phone? I did a search and figured I should ask in this thread.

I want to flash the latest Sleeper ROM but I've been told to do a nandroid backup first incase I have problems.
[Epic 4G Q&A, Help & Troubleshooting] KennyG123:
When you boot up into CWM right on the menu is backup and restore.
[Epic 4G Q&A, Help & Troubleshooting] TexasAggie97:

[Epic 4G Q&A, Help & Troubleshooting] notsosmrtgeek:
i had problems while i was restoring. but i think it is because of having a theme with a mtd rom. but i didn't try a different one. i am back to stock now i have to get my screen to flake out more so i can take it in.

edit: the backup would do the restore process just fine and it booted up but only the backlit keys would be on nothing else would show up. and the back up only took like 3-5 mins tops but i didn't have any apps installed you know one of those flashaholics

yea its a refurb. this is my 4th phone. and this one has been f 'ed from the get go when ever it is on a white screen say like when facebook 1st loads there will be lines that goes across the screen. some times there really bad other time there not even there. I dont get it but I cant take it in till it gets worse because sprint people will be like there is nothing wrong.
[Epic 4G Q&A, Help & Troubleshooting] ÜBER™:
Yep white lines :) sounds like the screen has an issue... if you could get a picture or video or reproduce it at the store then they'll fix it. On what rom did you expierence this though I know sometimes its because the kernels depending on how the defaults are set on voodoo control if of course that rom supports it.
[Epic 4G Q&A, Help & Troubleshooting] notsosmrtgeek:
it does it with stock but not as often. but any custom rom its worse. even before mtd. alot of it is when i am using heavy data. my normal is streaming pandora and while on xda and facebook. I know the screen was the worst on miui. it was doing big black lines and then the screen had this greenish yellow tint to it for about 5 mins. thats what made me go back. maybe what i should do is get a custom kernel keep stock take a picture of my phone with my wifes and then go back to stock and walk on in the store.
[Epic 4G Q&A, Help & Troubleshooting] ÜBER™:
Weird I know that when rgb's are real low in voodoo ill get this weird green tint to it but goes away when I start using it again its the backlight or the dimming when it plans to shut off.

Sorry I'm not following up on this thread as I usually did, this is due to whats going on in Egypt..

as I'm usually contribute in the protests so most of the time I'm not home

but I see XDA member "

Flashmaniac

" is doing a great job :)

EDIT : Check the Second post, it has a program he created that makes this process more easier !! :D

so I just wanted to thank him for his great efforts in the OP, and you guys should thank him too :)

thank you very much

Hi Everyone

this is my first contribution to this great forum...

first off and to clear everything up..

this is NOT my work, nor do I take any credit for it

the original creator of this work has removed it and I wont mention who he is so he doesnt get arrested by SOPA or The FBI or whatever is going on in the US:mad:

but I think we know him all ;)

so thanks to him I unlocked and S-OFF'd my EVO after having it useless for several months..

and I think other people should have this too

so, the SOPA and the FBI dont scare me and I take full legal responsibility of the contents of this tutorial..

I did this from the beleif that everyone has the right to S-OFF his device and fully enjoy its benefits like I did

and the fact that I achieved S-OFF before this guide got removed does not make me better than anyone

so enjoy

and please hope I dont get banned for this ;)

So ...

Hi Everybody.

This instruction for all version hboot and all main version.

1. Download all the files.

PG86IMG.zip Official firmware with European HBOOT 1.49.0007. Rename it to PG86IMG.zip

xvi32.rar xvi32 hex editor.

adb.rar adb.exe and fastboot.exe.

2. You need unlock and root your phone. htcdev.com for unlock your phone.

3. Plug Evo 3D in cherge mode.

4. Extract adb.rar to C:\

Run command line and enter next commands

cd c:\adb

adb shell dd if=/dev/block/mmcblk0p31 of=/mnt/sdcard/mmcblk0p31.img

Dont close command line and plug your sd card.

5. Extract xvi32.rar and open mmcblk0p31.img.

Change version in xvi32 1.22.720.1 to 1.20.720.1 and save file. (You version may be different? you need chane it to 1.20....)

6. Plug your phone in charge mode. Go to command line and enter this command

adb shell dd if=/mnt/sdcard/mmcblk0p31.img of=/dev/block/mmcblk0p31

adb reboot-bootloader

\\Change CId

fastboot oem writecid HTC__001

\\Lock bootloader

fastboot oem lock

7. Power off phone. unplug battery and copy PG86IMG.zip to root SD card.

Then power off phone to bootloader (vol down+ power button).

PG86IMG.zip cheking from phone< then you need press vol up for update, or vol down for not update. Press vol up. Wait.

You have hboot 1.49.0007.) Congratulation.)

8.Unlock bootloader from htcdev.com and s-off from revolutionary.io.

P.S. All manipulations you do at your own risk.

Just a quick question having downgraded hboot and achieved s-off is it possible to upgrade to original hboot without losing root or s-off
[HTC EVO 3D] s_superman:
no you cant I think

but why would you want to do that?? :confused:
[HTC EVO 3D] chubby65:
The 3d games that come with that rom are missing from the rom with the downgraded hboot but missing out on them is a small price to pay for s-off

Would u mind to advise step by step to root & flash any popular custom rom my unlocked Testra EVO 3D as I'm noob & new on this device?

Thank in advance and I'm living in Cambodia using this unlocked Testra device and just bought it from my friend today.

If I will do per your above instruction, and something goes wrong need to revert back to stock, will my phone be branded&locked from Testra again?

[HTC EVO 3D] s_superman:
follow the guide above and you will achieve s-off and you will be able to flash any rom or kernel

and you cant revert this process...

or maybe you can but there is a high risk of bricking

and its not worth it

it will display ***RELOCKED*** though...
[HTC EVO 3D] s_superman:
google those games and you will find them

and there is a 1.24 based rom lying around here somewhere that has a zip file containing the games and the dictionary

and fyi

hboot has nothing to do with games ;)

and you can download your shipped rom and extract the apk files for your games and push them to your phone...
[HTC EVO 3D] chubby65:
Just downloaded OTA update couldn't install so extracted thru root explorer and got games that way

I meant the games were in the original rom with upgraded hboot sorry about that
[HTC EVO 3D] Flashmaniac:
Just to let you know, changing the CID does NOT work if your device has no SUPERCID or S-OFF.

But you don't even need to do that.

Just change the version number to a ruu which has the correct hboot version.

I.E a Vodafone ruu. fastboot oem lock and run the ruu ;)

all what matters is the version number.

I did that twice already, its 100% working.

@s_superman Thank you so much for this great tutorial!

Here's my question: I already unlocked my bootloader with official htcdev.com method. So i have hboot 0018 and unlocked S-On. Can i still follow this tutorial to achieve S-Off? Are there special exceptions i have to take care of?

thank in advance

Or @Flashmaniac could you write a short tut how to achieve s-off and root with your method?

Does not work for Branded CID ie; Telstra?

Would be great if there was a solution, I would love to have s-off but tried heaps of different methods but still s-on. Cant write the new CID to the system only get CID to SD so I can modify with HEX editor and then with adb I put CID back then relock phone and place PG86IMG.zip on SD but it tells me model ID incorrect? I have checked my CID after changing it and putting back on the phone and it still reads TELST01 for the CID any ideas?
[HTC EVO 3D] Tuna9351:
I can probs say that this didnt work for aussie branded phones as i saw this previously on other threads amd tried myself only to be confirmed by others on the aussie networks like telstra voda and optus i can live with the htc unlock tho as im flashing leedroid atm with no issues wifi inclusive. Just hoping someone else finds a way eventually to soff aussie branded.
