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... :,(

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'
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
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...
Just got a new Galaxy S5, activated with sprint, installed custom recovery, rooted, install rom, etc. KNOX tripped btw
So even before I modified anything I was getting a bunch of network errors. After I rooted and installed a ROM I still get the networks errors, no 4g.
I went back to stock, unrooted ROM, still get all the errors, no 4g, no OTA update because it says my operating system has been modified. Then it says because of network issues my sim has been locked, then a few minutes later it says its unsable to detect my sim and will restart to check for the sim.
And I also get a bunch of apps stopping error messages.
Could the knox trip be preventing the OTA since I reverted back to stock non-root?
ALSO, right now it says theres no sim, but I have 3g and I'm making phone calls
Just got out from the sprint service center. They fixed the network problems in about 2 minutes. He said it was something where the sim wasnt set up right on their end. It worked to make phone calls and to receive 3g, but wouldn't get 4g. He pushed a few buttons on his computer and had all the network problems cleared up. I'm not worried able any other problems at this point because I'm sure they can be resolved by flashing the right rom.
So ive got a spint s6, bought from dubai, unlocked and rooted apparently. After a couple of days, my phone woulndt start up cuz it was FRP locked. OK so i searched for the original firmware, i flashed it and my phone booted up again. i flashed also the 5.1.1 and 6.0.1. Here s the thing, on 5.1.1 i can make calls, receive them, receive text messages but i cant send texts at all, so my guess its that its not unlocked anymore. On 6.0 doesnt even have any signal so forget about it. I just want to resolve this issue. I cant find the setting that could help me to change the message center at all, i dont have that option in my phone, i even tried to change things with some adb commands but still nothing. So after all my guess its that the phone isnt unlocked anymore and if so, how do i unlock it? i just cant give the phone back cuz i dont live in dubai, im like a day or so distance with the plane so i just wont go back there again. If anyone could help me...please do so...im on 5.1.1 now, unrooted, i can root, i just cant send texts and i dont have the messages center
oh and also i tried the galaxy tool method from idoneapps which apparently wont work at all and im concerned about paying for that thing if it doesnt work so...yeah
