[Q] Sky ICS 4.2F "Connection Problem or Invalid MMI" - AT&T Samsung Galaxy S II Skyrocket SGH-I727

I just flashed Seanzscreams's latest ROM SKY ICS 4.2F-2.5 with the RUXLF modem, and tried to punch in the *#2236# code to LTE/Auto it and got "Connection Problem or Invalid MMI". The phone works fine, as I was able to speed dial out of contacts.
Sean posted that you need not pull the SIM card for this operation, so the first few times I did it (and I've reflashed the full monty, with wipes base and everything a couple times now), I didn't pull the SIM. THis last time, I did pull the SIM and ust got a "No Mobile Connection" message. Popped the SIM back in and came back to the "Connection Problem/ Invalid MMI" message.
Any thoughts?
I've also had problems connecting to my Exchange server at work, though I had it working fine in the stock email in Sean's 4.2E. I was able to connect to the server with K9, but that program seems to suck. Anyone have a suggestion for a better Exchange-friendly, push-friendly email app? Thanks!

check checksum or redownload rom for ur device rogers ot att

I've reflashed, not sure about checksum.
How do I check the checksum?
I've now flashed both ATT ROMs and the 2.5b update. I'm going to flash the 3.5 here in a second and see what happens.
Worst case, I roll back to 4.2E-17, which worked great for me. BUt I don't know the cause of this problem, so diagnosing it is a *****.
Anyone get this?

"No SIM card" initially...
Hello. This is my first post in this forum. I have flashed this ROM with the 6/27 update for an AT&T Skyrocket. I'm experiencing the "No SIM card" message for 5-10 seconds, then it seems to connect to my 3G MicroCell and work fine. I followed the directions for this that I found after searching the forum, with *#2263# and so forth, but it doesn't make a difference. One thing... I placed my AT&T account in suspension while I experience, ummm, "job transition." My MicroCell recognizes my number, though. And when I atttempt to dial a number the system at least recognizes my number.
Otherwise I'm loving this build! Any help would be appreciated, and let me know what else I can tell you to help answer the question.
UPDATE: I hadn't restored my latest backup prior to this. I did (apps and system data) and it doesn't do it anymore. I know that doesn't help much, but there it is...

Doesn't work with SkyICS
I wanted to unlock my Skyrocket, but the #0111*CODE# wasnt working, kept getting Invalid MMI Code
I had to restore my GB Stock Rom and I was finally able to unlock my SR

Help Please - Emergency call only on all roms

Hi,
i have rooted etc.. as per the many wonderful links on this site and have been swapping between various roms for a number of weeks now.
However today, all of a sudden i dont have a connection to my network, and am being told that i can only make emergency calls. Currently have ionr3 lite, and all was working 100% this morning.
If i go into settings and try to manually select vodafone i get the error messgae 'Your sim card does not allow a connection to this network'. And if i go into APN's this is blank
Have checked my sim in another handset just to make sure that the sim wasnt the problem.
Any help much appreciated. Thank you in advance.

Help; I've destroyed my phone.

Running an HTC Touch Pro 2, Verizon. Saw the update, and saw the Cookiemonster/Energy ROM preview; though it looked sweet.
Flashed HardSPL.
Flashed Cookiemonster/EnergyROM CDMA. Was working fine; but my wife is the primary user, and she wasn't comfortable with the interface. Flashed the official 6.5 update- phone was no longer able to connect (making calls gets a prerecorded "Cannot authenticate at this time", SMS messages can't be sent, no internet connection, etc.)
Tried *22899, and *228 option 1; have re-flashed both the official rom, and the April 17th build 21899 "sense UI" version of Energy. Both have the same issue. Calling the phone causes it to ring, but the call instantly hangs up as the ringer starts to play.
At this point, I'd just like to get the phone back to stock... Can anyone provide me with the instructions to get this back to Verizon stock?
Any help is appreciated; Thanks!
Just flash the stock rom by usb or sd card. Also you need to call verizon and ask them to authenticate the phone because you did a hard reset.

Do exactly what the previous poster said.
When you flash to the official ROM it wipes out the A-Key. My prefered method: Rather than calling Verizon, if you have another phone, just activate that, then reactivate your TP2. That will generate a new A-key and save you the phone call to Verizon. 'Using Verizon's Online Web Activation'

[Q] [HELP] Heat and signal problems on ZTE V970

Hi to all, I'm writing here because I had my first problems with my v970 (with etotalk rom). This evening I checked my mobile and I found that none of the sim was active (I was not in airplane mode) and I could not activate them, as if they were not in their slots. Meanwhile the upper part of the device began to heat up, so I tought it could be an antenna/receiver problem. I almost forgot to say that I installed Truecaller (deleting Contapps) and updated facebook and few others apps less than one hour before the event, but I already uninstalled them to exclude some of the possible causes. I'll gladly listen to any advice. Thank's in advance. GL
Restart, and see if it continues.
Already tried a lot of times, with or without sim cards. I also noticed an abnormal use of battery.
When did the problem start? What did you do before it started? Does your cellphone always have no signal, or does it come & go (sometimes SIM works, sometimes it doesn't)? Have you checked your APN settings?

The problem started yesterday and I never experimented It till now. As I Said, before I encountered It, I updated some apps from the market and I changed the default caller manager (should I call It in this way?) with Truecaller. I also deleted my sim contacts
. I can't check apn because there are no apns to check (Android shows me the voice "mobile networks" but I can't select it
Update: I tried to restore the original rom, but the problem persists. I also made a check with the recovery, and it shows me that the device cannot detect sim cards. I begin to think that it's an hardware problem (ouch). Am I right?
What did you do in recovery that checks SIM cards? Are you talking about CWM recovery?

Nope, it's the faulty recovery that etotalk sent me with the phone. I would like to install the cwm and flash another rom, but I'll leave that as the last option
If the recovery they sent you is faulty, then what good is it? If there's a custom recovery available for your phone, you might as well go with it, not that it'll solve anything by itself.
You might try inserting some kind of shim along with the SIM card to see if the extra pressure help make contact with the leads. Careful, of course, that whatever you stick in there doesn't stay behind.

I know about the recovery, but I was trying to don't invalidate the warranty (as if I'll ever use it...). Now I'm charging the phone, it's already the third time today...
Aw, heck. If you've got warranty, just send it in.

Yep, I've got warranty, but sending it in China will cost me almost as much as buying a new one
Ok, I flashed a recovery and a custom rom, but nothing happened.The signal is still absent and the antenna heats up the same way as before. I tried to enter engineer mode and it shows me messages as "com.android.internal.telephony.CommandExcepti on: RADIO_NOT_AVAILABLE", "3G off. Cannot set", ecc... It also shows me "invalid IMEI" if I try to look at it and I cannot change it back with the AT +EGMR command (it says "Radio on" and "SIM State: ABSENT", altough the SIM card is in its slot).
I think you have to crack the case.

Hmmm... if your phone is reporting invalid IMEI numbers then I would try first to get that working as it should. Read this tutorial and re-write your IMEI numbers.
Then I would try the latest stock ROM, which is available on ZTE support website. Here is the direct link to the ROM.
If your phone still doesn't work after that, then I'm afraid you have a hardware problem.
I have had the telephone for more than one month with no problem. Trying every ROM made by Bruno with no problem at all with signal, but...
About 4 days ago, I started suffering exactly the same problems stated by ArcheoGian. I have tried everything (installing older Roms, rebooting, changing SIMs from 1 to 2, etc.) but unfortunately with no success. I just have to try to install the original ROM, but I supose it will be the same.
Afer a few reboots, I can make the telephone to search for a network, it founds it, it connects, it transfers data, I can make calls, but ramdomly (can be after 30 seconds, 30 minutes or maximum one hour) it disconnects and the red X of death (Xbox 360 times ) appears on top of the screen.
I can try to go and return from airplane mode, or search for networks that it won't re-connect.
I fear it can become a typical problem for this phone.
I am "delighted" to send it back to China and wait for two months to get it back (after explaining it to the seller and so on). Fingers crossed
@prinxo: did you buy it from eto...k? (I don't know if I can write the entire name of the seller)
Update: I tried everything it was told me (except to crack the case, at least not yet...), my last hope is to manually insert the IMEIs inside the data folder. There's just one problem: none of the methods suggested in the link posted by bcgngm works on my phone, so I need to generate the IMEIs whit my pc (I couldn't open the exe with windows 7, I'll try with win xp in a while, otherwise I have to ask someone to create it for me).

No, I bought it from another seller at Aliexpress.
As I thought: I tried to re-install an original ROM, and everything remains the same. I thought I was successfull but after one hour the phone disconnected itself from the network. After that moment, I need about 3 re-boots to get signal again and it lasts for just a few minutes.
At this point, I would disregard a software problem.
Happy happy to have to send it back to China.

Why do you say it is not working? My preferred method is to use the adb commands (and for that you have to install Android SDK). Don't forget that when you type the commands there is no output message on the screen. The phone has to be restarted so that changes take effect.

The third and the fourth ones are the only methods to restore IMEI I didn't try, just because I never used sdk and adb (and I'm not sure to be able to use them). I followed the others options (I also created the IMEI file with the russian program), but it continues to show me the "invalid IMEI" message. Can you help me, maybe showing me a good walkthrough?
This ADB Tutorial looks easy to follow. Check it out!

[Q] No phone Calls, only data and text

I got this phone a month ago and flashed various stock based ROMs with no trouble. I then tried AOSP (cm10.1, eclipse) and everything seemed to be ok although, I couldn't make phone calls because I have no service where my house is and was never able to test (I remember that in settings->about phone->system status it said it wasn't activated and it didn't display my phone number, but when I went back to stock it did display my number). Then I went back to a stock ROM and my phone would not make or receive calls. It would send and receive text and was able to received data via 4g but when trying to make a call, it would say "dialing" and then eventually just stop without making any type of connection. when calling the phone it would go straight to voice mail as if it was off. I used odin to go entirely stock and had the same problem. I ended up returning the phone and getting a new one and I am running Clean rom 5.5.1 and everything is working fine but I'd really like to try other roms but I don't want to have the same problem again. anyone know if it was just a bad phone or if I did something wrong? if so, what? any ideas would be greatly appreciated! Thanks!
You should have consulted xda before returning the phone. With your original phone, you needed to reprovision your sim to properly have your data return since you had Odin flashed. That code only works on ICS though.
The loss of data on your prior phone was from flashing CM10.1, you just needed to follow this post to resolve your issue without Odin flashing a stock rom.
Edit: The sim reprovision code suggestion is still valid BUT disregard the data loss part...

[Q] I can do everything except make calls! please help!

I have a Mexican S2 LTE i727 Skyrocket from Telcel.
I rooted it, unlocked it via a web code i bought, and after a few hiccups everything seemed to be working fine (GPS, Wifi, installing and using apps), i did try to keep blocked cellphone data because i dont have a plan yet.
Yesterday i received my 1st call (not my main phone yet) and i found out that i cant make a call longer than 15 seconds!, as the phone will cut audio, or hang up, or restart the phone all together...
The only thing weird i can think of, is that when i first unlocked the phone is said "SUCCESSFUL" and 14 seconds later "FAILED", i restarted and changed roms a few times, and kept being locked...
I tried the alternative methods they sent me by mail and did something that apparently unlocked it successfully, because now i dont get any message when i insert a different SIM, and the carrier name actually comes up (2 different carriers), and everything seems to work...
BUT when i dial *#7465625# to confirm if the phone is unlocked, i get a "Unfortunatelly, the process com.android.phone has stopped." message.
*#06# does gets my imei correctly (a different ROM said it was 0, I changed roms and i could see the imei correctly again.
I tried changing to different mods, like Embyro 6.0, Embyro 6.3, Embyro 4.1, CM9.1, CM10.0, ATT stock deodexed, ATT ICS 404, and a few others... and its the same with every one the phone will hang up, or reboot or lose all audio in or out. (it wont pass the bootscreen with the actual TELCEL stock rom from sammobile)
Am i missing something? a test i could do to see whats wrong?
Could it be a hardware issue? any other *# codes i could try?
also... Anyone out there has the official TELCEL firmware/rom??? or an alternate source for some reason i cant get the one from sammobile to work and i was planning on taking it back for warranty if i confirmed its a hardware issue... :,(
