[Q] I727 in Vodafone.de, 3G strong signal but no call in/out no data flow - AT&T Samsung Galaxy S II Skyrocket SGH-I727
Hi guys,
I have a i727 skyrocket use in Germany. (unlock phone)
The network provider is Vodafone.de.
The phone works fine if you only use it in 2G network both call and data. (stock rom by using *#2263# or *#*#4636#*#*, CM9 rom by select 2g only, or *#*#4636#*#*)
But when I turn it to 3g network, problem happened. (both in WCDMA only or WCDMA preferred)
It appears like, when you power on/restart the phone, at first you can see 4G (stock) or H+/H/3G (CM9) icon and the data arrows flash. At this period you can make calls or browse website. But after maybe 30 seconds or 1 minute, when 4G or H icon gets stable. Then you can’t make calls out and if you use another phone to call it, the voice tells you the number you called can not be connected. And also the data was stopped; the browse shows network problem/times out or the same kinds of notice.
Then I use “GSM Signal Monitoring”, try to find out some regular patterns. I found when the signal switch from one base station to another, at first the phone functions is ok, and later when the signal is stable, the phone dead, and maybe several minutes after, when the phone switch to another station, the phone function works again, then about 30 seconds later, dead again. But in all this periods the signal is quite good. (around -60~-80 dBm)
At first I think maybe is the problem about RADIO.
So I try to flash many different RADIOs (T989, T989D, I727R, I757M, I9210, I9210T, E120K, E120S both from stock 2.3 or 4.0 and both with or without RIP), but they all didn’t solve the problem.
And also I try different ROMs (stock 2.3, 4.0; I727R 2.3, 4.0; T989 4.0, CM9; CM10), and the combination with the radios above, but still didn’t work.
Then I noticed some threads about the fast dormancy, I have tried to turn the fast dormancy off or on. But still didn’t work.
Also I noticed about different 3G data forms (HSPA+, HSUPA, HSDPA, UTMS), then I used *#301279# on stock rom to fix the 3g data form in only one kind or only use UTMS, but still didn’t work.
And later I found it is not about the data connection, it is only about the 3G network no matter about the data is on or off, when you switched to WCDMA, then, when the signal stable, you can’t make calls out or receive calls in, and even the signal bar seems great from the begin to the end.Another thing is if you making a call at the first “alive” period, then before you hang up the phone, it all works. Also if you use some online radio software keep the data flow, and the phone will not “dead”, only when the phone is idle, and later after sometime, the signal “dead”.
And the SIM card works fine in other phones in 3G network.
I have tried this in my home and office. In the office the signal always switched to different stations, so it looks a little better. But at home, the signal always stays in one or two stations, so it much easier to see when signal stable, the phone dead.
This problem confused me already 1 month, I tried everything I found and everything I can image. But everything didn’t work. At this moment, I only can use it under 2G networks.:crying::crying::crying:
I am sorry about my English; I try to explain these clearly.
Really hope someone can help me.

Why are u flashing radios for other phones???? That cud be ur problem right there.....try flashing a modem/radio for the i727 skyrocket
Edit: try flashing one of these radios for the SKYROCKET.....if that dnt work u may need to warranty ur phone out and get it replaced.

because from the begining the original rom and radio have this problem,
then i have to try some other radios,
hope may solve this problem.
but neither the stock nor other ROM/RIDAO works. ............

I did the same as you, tried a lot of rom/kernel/radio combination without any luck.
Im not in US too, and I notice something that when it happens the network type changes from HSPDA to Unknown, but my carrier ID still there.
I Think that is happening maybe because I don't have a LTE signal here and the phone tries to connect to something in that band frequency and it somehow "hear" something in that frequency then lock it up there.
I notice that if i got into the radio menu *#2263* ( depending on the rom u r using) and set it to be just gsm. I will always get calls and data, but in eDGE speed and it sucks... If i set it to WCDMA only it eventually get signal drops. And the last choice is that Auto mode that I think got the LTE enable. I think if we could select the WCDMA preferred/ GSM option of the radio i727ruxfl3 it would solve our problems, but it appears to be an invalid solution.
Ive been looking around to learn how to change the radio code but no lucky yet...

In my case, the network type changes from HSPA+:15-->UTMS:3-->HSPA:11, then stop changing. If you send some internet request immediately after this, the network type will change back to UTMS:3--> HSPA+:15 again. But If you do nothing, after some time, the network fully dead.....Only when the phone switches to anther station, the network type changes again. Because I noticed this, I tried to fixed the network type in HSDPA:9 or UTMS:3, but the network still will die when the signal stable.
In my place, we do have a LTE network, but the frequency here is different from north america. And my problem is only in WCDMA, so I think it is not related with LTE network.
As I said, it works well in 2G network both in GPRS and EDGE; and in 3G, the signal is also strong, nearly full bar.
Maybe my case is a little different from yours.
But in your case, I think you can use *#*#4636#*#*, to lock the signal in WCDMA only or WCDMA preferred, it is the same as you use *#2263#, only the words is a little different.
WCDMA only in *#*#4636#*#* = WCDMA preference in *#2263#
WCDMA preference in *#*#4636#*#* = WCDMA/GSM preference in *#2263#
You can try to test whether your theory is right.

Im using SuperHeavy JB rom and Blaze LF4 radio that is the best combination i got so far. I still get network lockouts but its not as common as other combos. My theory is that the radio connects to some band then it loses the signal and somehow it doesn't detect that the signal is lost.
Cause I was looking at the *#*#4636#*#* and the uplink still sending data, but it doesn't get a response back.

Yes, I am quite agree with your theory.
I noticed the same thing as you mentioned,
When the signal is dead,
you still can see the phone send some request to the network,
but no respond.
So I think it maybe influenced by the fast dormancy.
Maybe the phone and the network have some problem in fast dormancy policy.
Then I use the way which was described in the forum, add some information into the database.
But unluckly, still didn't work.
I will try your combinations to see if something changes.
Thanks a lot.

report:
I just tried this combination, SuperHeavy rom (V6.0SR, based on CM10), and blaze 4g LF4 radio. But still the same, the signal dead after the signal is stable. T_T
You can see a H on the bar, and the signal if full.
But when you use "ping" in *#*#4636#*#*, the result is "Fail:IP addr not reachable"

The first is when the signal is satble, have a "H" icon on the bar and the network connection is "stop".
At this moment, you can see good signal, but you can't make any calls, and no data.
The second is just when the phone switched to another base station, have a "H+" icon, at the first short moment, everything works find.
But, several seconds later, the "H+" turns to "H", then, every communication down.

I wipe everything and started a new installation. The rom version is a gingerbread one. I thought what the heck i will do the downgrade, better a working phone with an old OS the a great OS with non working phone.
I tried the Nexusmod 4.3.1 with the radio i727UCLA3. Its been just 4hrs tethering but so far so good. Give it a try.
Another thing is looking down the web i found that more ppl are having this issue, but they are using other devices such as nexus,and they fixed by simple softwares updates, I might not be the same problem but it gave me hope that it could be software related not hardware as I ve started to suspect.

Hey Im trying a new thing, I took out the SD card and changed the SIM card. I have installed the CM JB 4.1.2 nightly,after that i let it settle for 10min before I do anything in the room. Well since yesterday i got data and calls whenever I want.
You should try.

The same I tried, took out SIM card (no install TF card), install clean ROM, restart, let it settle for half an hour, then, insert SIM card.
Unfortunately, still the same.
But I found some thing, when I use my frineds' SIM card which from other network provider (O2, E-plus in Germany), and the phone in their 3g network seems works well.....
So maybe this only about the phone and the vodafone network, maybe some compatible problem. It is really disappointed.
I contacted with vodafone company but no reply yet.
I think maybe the only way I can use this phone properly is to change to another network. T_T

Connectivity loss between H+ -> 3G = annoying.
When in a moving vehicle, signal often changes from H+ to 3G, and vice versa, and this brief change results in connectivity loss for a few seconds. Sometimes this loss of connectivity compounds to a minute or more, because of how often it changes, and I can't do anything with my phone (from simple texting to streaming). Is there anyway to stop this from happening? I suppose select to use 3G permanently, and no H+? I read somewhere that H+ and 3G work as "1 spectrum", and you cannot disable one without disabling the other... is this true?
What rom and radio are you usin?
Tx Redneck said: What rom and radio are you usin? Click to expand... Click to collapse Inspired Ace v1.0.1, latest AT&T ROM (06.06.30) with corresponding RIL (2.0 or w/e). I don't think it's connectivity issue on my phone, it's just me going through H-supported areas, and the phone trying to connect to it.
My phone has been doing this all day. :\ It's actually stuck in 3G right now. It changes to H+ for a couple of seconds before reverting back to 3G.
[Q] Different Roms, Different Radios, Same Problem
Background: I'm on AT&T, Unlimited Data. I've had my Inspire 4G for about 4 months and for the most part I have been running Leedroid. Recently, I've been having trouble with not being able to make calls, but able to receive calls and use data. When I try to make a call it drops immediately. As soon as I press Call, it flashes to "Call Ended". I thought that a clean wipe and flash would solve the problem and I've also made sure that I'm running the correct radio (Suggested radio) and matching RIL. Neither of these ideas fixed my problem, so I flashed CM 7.1.0-RC1 and again checked the radio firmware and RIL. No dice. I've tried to search around the forums to make sure I wasn't overlooking something obvious, but I haven't found anything. Also, I do have a good signal when I'm attempting to make a call. It seems to only happen in one part of town and I'm wondering if it's something to do with this part of the network. Sometimes if I cycle the radio on and off using airplane mode it will work long enough to make one call. Sometimes if I go into the Settings > Wireless and Network > Mobile Networks > Network Operators > and press Select Automatically, It re-registers on the network and all is fine for about 30 minutes. Side note: My data speeds have dropped from 4000kbps to about 700kbps. Current info: Android 2.3.4 Baseband 15.54.60.25U_26.09.04.11_M2 Kernel 2.6.35.13-cyanogenmod-g87a2eba If anyone has run into this problem or has a suggestion I would really appreciate it. Thanks in advance.

Click to collapse Data can be different at different times at&t is notorious for that. its odd that it only happens in one part if town, that leads me to think that it has to do with towers and signal. If it was happening all the time, I would think different, but it only happening in one part of town, and it only recently happening, thats signs of tower/ signal issues I would think. Sent from my Inspire 4G using xda premium
I feel the same way. I'm going to run an experiment today. Using Open Signal Maps, I'm going to note the tower that I'm connected to when I start having problems. Then, I will drive a distance away until I have connected to another tower and see if that resolves the problem. Otherwise, I'm still stumped.

Click to collapse Yeah, I've tried that. Didn't work. Thanks though.
Just for grins, you could try a different radio. 26.09.04.11 was never released on the Inspire nor the AT&T network. Keep in mind that Lee is overseas in the UK using another network provider, so I would take his recommended radio with a grain of salt. If I were you, I would try 26.06.06.30 or 26.10.04.03. If you're using a Sense ROM, then use RIL 2.2.0160HM with it. If you're using CM7.1.0-RC1 or a newer nightly, then stick with the default RIL (2.2.0018G) because it's tuned for AOSP ROMs and is known to work very well with all stock Inspire radios. Regarding your poor data speeds, be sure to reconfigure your custom ROM to use the stock APN settings. No custom ROM on this forum (except for those heavily based on the stock ROM) comes with the true proper stock APN settings that are needed for full speeds in some markets. Link to the APN settings is here.
Network issue during roaming
Hi, I am facing network connectivity issue since the time I entered roaming area on my Matrix 2. It does not connect to network. It keeps showing no network, then for 2 seconds it shows emergency call symbol , then for 2 seconds it gets connected to network and again it keeps showing no network. This cycle keeps on repeating. I searched for the issue and found that it is issue with atrix 2 software and the suggested solution was to install app called network and choose gsm only from it. I tried it but it doesn't works for me. I am able to make a call if I dial number exactly at the moment network appears for 2 seconds. The only temporary solution I was able to find was to dial self number as soon as network appears and then keep on dialing it for around 8-10 times. Then it gets connected to network for 1/2-1 hour and then again it gets disconnected. Please let me know if anyone has any solution for it. I am on JB unrooted and using 2g network.
1) Try another SIM .... 2) try flashing ICS radio.img ...... (you shud know some fastboot commands) search the forum 3) try factory reset or reflash JB ..... it might work sometime if you are using BSNL ..... then i have my sympathies with you :silly: lol
First off wrong forum, should go here http://forum.xda-developers.com/forumdisplay.php?f=1771 Go back to Stock ICS via RSD Lite 6, try SIM with other phone first and check, do not install apps for network improvement as mostly they just turn radio on & off, in worse case they can botch up some internal default settings.

Thanks for the reply... I have already tried that, its not a network or sim card issue. I have tried inserting sim to other phone and it just works fine. I put it in general section coz when I googled it I came to know that its an issue with every atrix-2 so every one might have faced this issue while roaming. Also going back to stock have not worked for anyone. Its an issue with atrix-2 software itself.
You seem to have reached to your own final conclusions but yet please understand on JB 4.1.2 leak there has been no one who has echoed your issue (gps is definitely an issue & for some wifi on some particular bands). Also read this http://forum.xda-developers.com/showthread.php?t=1425560 Try flashing the new 4.2.1 ROM based on official leak of 4.1.2 JB as I believe radio is better on it. On JB leak though one thing I can confirm is when phone enters roaming it automatically shuts data randomly and not always & user has to re-enable it. If all fails, fxz to stock ICS and if under warranty claim your stake.
Thanks...will try when I get back to home. Although I have not reached to conclusion on my own, I search regarding this in Motorola forums and people facing this issue stated that they tried aall the specified methods. They were getting this issue on all os versions.
Please point me towards a link which illustrates issue same as your on JB 4.1.2 specifically.
[Q] OnePlus One modem/radio issues!
This is what I told support, but they wouldn't help me: I have the GSM and 3G frequencies, but still it disconnects for a 15 seconds to 3 minutes a few times a day.. It disconnects from all phone services, even though I have great reception/signal. Why? How can I fix it? I saw this 'preffered type' of network or something in these advanced testing settings where you could change between alot of different network types like WCDMA, TD-SCDMA, LTE and so on, is there something I have to change there? If it helps I live in Norway. "" So this has been going on for a long time, now I got a suggestion that it might help to flash new radio software (.zip?). I know about adb, fastboot and flashing using recovery, but I don't know what radio to flash, if tharæt's the problem. The phone can also use 15-30seconds to turn on WiFi, from what I know this might also be related to the radio software. If you want pictures or more details, just ask Thanks in advance!
Hello Whitch software? Just for test: switch off the wifi and test that your problem goes away or still present.

If possible try to switch off the wifi and test it.
Phone modem/radio dead?
Not sure if the phone radio is completely dead or not but I've lost all signals completely today. Nothing I do works. If I go into Mobile Networks and choose Network Operators, the phone is able to scan for the networks and showed my correct carrier in the list. However I choose to register on it, it doesn't work. It just keeps scanning and doesn't register. Tried flashing new ROM from scratch with new radios from CM and Oxygen (230 and 241) and neither works. Tried flashing via recovery and fastboot. Tried restoring from a working TWRP backup, still the same issue. I took my SIM card out and tried on an older phone, works fine. Used another working SIM card on my OPO, still doesn't work. At this point, I think it could be a hardware issue with the phone. Only thing I'm confused about is why it's able to list the carriers in Network Operators and this was never an issue in the past. Also, it doesn't show a question mark in the signal bar so that would lead me to think it's detecting the network but not fully working or registered on it for whatever reason. All I see is completely no bars in my signal bar. I can't dial or receive calls, I can't use emergency calls, but it does pickup my network as Vodafone NZ. Any ideas? Update: Switching to 2G, 3G and LTE doesn't do anything, still no signals. Also, looks like the Network Operators function is irrelevant to your SIM card. Unplugged my SIM and it was still able to scan for it.
I suggest you to try kitkat modem on lollipop os. I know someone has the same problem with you .I dont know why but some OPOs does not work with lollipop modems.

Yes, I do see my IMEI. Have tried all the solutions there are.......flashed oxygenOS, colorOS and imei is still there. I can see there's signal under About -> Status, but no network (unknown). My wifi works fine, just no phone signal. My sim card is fine, tried on other phones and it works. Tried several sim cards in my OnePlus and they all fail. Wasn't like this last week, dunno what happened. I think maybe my IMEI is blocked? I called my carrier and they said it's not. Will i need to contact OnePlus (my phone is the chinese version) to get this resolved?
Same problem. No reason. Just started happening last week... I tried another network and it worked though.
Exactly the same problem here. It first happened when I traveled to Japan and inserted a Japanese SIM card, nothing worked, so I thought it's because of the strict radio regulations in Japan....now I'm in Ireland, popped a 3 Mobile sim card in, still not working.....God I would never buy a OnePlus product again....first the touch screen failed, now the modem......biggest mistake taking it travelling with me....
@chaoscreater @dahole @victorinoxs I have your same problem IMEI, Baseband and WiFi are OK but no signal and status network unknown

Click to collapse I am having the very same problem and, once I opened the One up I found the connector was disconnected. But ... how to connect it back? It looks like it's a very difficult task to be accomplished!!! SOLVED! You can gently pull the pig tail cabletowards the center of the battery compartment, you connect it then push the cable back in. The small narrow cable compartment that's on the side has a "soft curtain to keep the cablew in place. Be careful to put everything back in place properly.

Click to collapse Antenna goes to bottom board near battery under rubber cover that you can unstick, connect and stick back. Just disconnect battery and pull antenna to the side of power button until you will be able to connect

Same network issues !! Hello everyone !!! I'm new here and so dont know much how stuff works here. Hope to learn pretty soon The thing is, I'm having similar problem with my OPO. I get only 4G network, no other network (2g/3g) gets connected. When on 4G, network randomly drops and connects, and when connected I can use internet, but just cannot make/recieve any calls. I have flashed many custom ROM's but to no avail. Finally after getting nowhere near solution, I stopped trying and currently I'm using Lineage OS (ver 14.1.20171001-NIGHTLY-bacon). Drmuruga posted a link with CM13 modem zips, will flashing the CM 13 modem file work in my case ? If yes, there are two files on the link you provided, which one should I use ?

I am on Airtel (only 4g). I've tried using docomo as it is my secondary sim, but it never connects since it works on 3g network. I've tried a couple of those from the list, but failed. Anyway, I'm gonna try the rest. Does TWRP version matters ? I'm using 3.1.1-0.

I've tried almost all firmwares from the link you provided using TWRP, but no luck. Maybe my card slot must have some hardware problem. Just to give it one last try, can you tell how I can Install those firmwares via ADB fastboot ?

Ps- It could be network antenna.Any recent activity that could damage the phone's hardware? Jio 4G,Bsnl 3G and Airtel 3G works fine here.I'm gonna get my Airtel 4G sim tomorrow,and I'll keep you posted if it works too.
