[Q] Beginning to hate my s2 (help) - Galaxy S II Q&A, Help & Troubleshooting

I'm pretty new to the whole root and flash. I did my research watched plenty of videos and went ahead. Managed to root and then flash. I currently have neat rom installed but I'm getting a few issues I can't seem to find info on or to fix. The 2 main things are
1.my phone will only use Internet on the H+ and will no load on anything but this (except wifi). It shows all the signals but whenever I want to load the Internet it flicks to H+ and loads sometimes I may have to retry and load the page if it doesn't switch to H+.
2.ive read to fix this if I type in *#301279# and change some settings. But when I type any code in it says invalid mmi code or connection problem. To fix this I've read it needs to be stock dialler but I assume neutron has the stock dialler.
It's beginning to really irritate me as the data won't work and when I use ttorrent I get really slow speeds because it switches back to H when I exit even tho its still downloading and half the time I can't get the Internet.
My phone was unlocked and I am on 3 network.
Oh and I've tried flashing a different modem and it doesn't help.
This pic is of the firmware etc.

You need to keep flashing modems until you find one that works well for you/with your carriers network (hint: logic says try the modems bundled with stock roms released by your carrier first). Flashing one isn't nearly exhaustive.

The modem I'm using at the moment is one from 3 network from what I'm aware.

Just downloaded a findril app and it says this. Could this be a issue? I'm not to clued up on the ril side . I've just puton a matching rril. Issue not solved.

And that's one modem from one stock rom. First up, you need to try the modems bundled with other stock roms released by your carrier (every modem is different/a Samsung 'black box', and there are dozens & dozens). If you still have no joy, try modems bundled with stock roms released by other carriers in your country. Still no joy, try any/every other modem bundled with stock roms released by other carriers world-wide.
This is not going to be a simple fix, it's going to take trial & error on your part.
I personally wouldn't start messing with RIL's unless I'd tried a couple of dozen modems without success.

Well I after the rail and for some reason it deleted my baseband, so I refreshed the baseband and it said complete but was not on after reboot and I couldn't get a signal thank god for back up.
I don't think it's a signal issue. The issue is the Internet won't load unless it's on H+, before I flashed I never had this issue.

Update, when I changed my ril my dl speed on ttorrent was 1.2mb now I have restored and gone back before the ril change I'll be lucky at getting 200kb dl speed. Does that show that my ril and baseband do not match and is causing the issue.

[FIXED] Radio Flash: No Sim

I have a quick question because I've run into a problem I can't seem to fix.
First, so everyone knows what I'm dealing with:
Phone: i717
Changes: Rooted (Shows super user access), CWM v5.5.0.4, Unlocked (Tested)
Rom: Stock AT&T Rom
Sim Card: Works in a T-mo branded Exhibit II 4G.
I flashed a radio (tried KID, 0331122 from the radio thread in the dev section, and reflashed the original AT&T radio).Even w/ the original radio installed, it cannot seem my T-Mo sim now.
Do I need to flash a new Rom or what? Wipe data to factory reset?
I would rather not change anything w/o asking since flashing radios seems to be a straight forward thing that most ppl have done w/o touching the rom.
Thanks ahead of time.
Mine worked with a rooted stock rom at first it didnt see the sim then i tried searching the network under wireless and networks it took a few minutes but then it came up.

don't forget if you are running an ICS based ROM you need an ICS based Radio/modem.
EDIT: i see you're running the original GB rom so you need the GB radio.
give it a few minutes to find a signal or go to settings/mobile networks/network operators. choose manual. then let it search a few minutes. then select t-mobile.
I find the Blaze 4G radio worked best for me, but depending on your area, your results may differ. try em all.
You guys are insanely fast.
I'm currently on the stock radio & I'm still getting the same message after letting the sim sit in the phone for 9 minutes (yes, I watched the clock, lol):
Insert SIM card to access network services

Where should I go from here?
Edit: Is the answer flashing another rom? Maybe something has become corrupt? I don't see how as I've read & re-read walk thrus for doing this to make sure.
I've done a little more reading. Flashing the beta ICS rom flashes to the old AT&T modem.
Would this be the best bet?
Edit: After looking through the "about" phone...
I'm on 4.0.3
Baseband: Unknown............. that's really bad.
Edit 2:
After reading, I needed to back up the EFS. No where is this stated anywhere, unfortunately. That contains IMEI and everything else.
Edit:
So, after reading MORE, the IMEI number is on a sticker behind the battery, along w/ the S/N.
Huh? Efs? I dont even know what that is nevermind backing it up. Goto clockworkmod and flash the radio.zip and reboot. Thats all there is to it.

If you look up EMEI number related to flashing the radio, there's a lot of hits.
XDA has a thread on it here: http://forum.xda-developers.com/showthread.php?t=1352371
I'm quite shocked it's not mentioned everywhere as this happens to people now and again.
I have my IMEI number, i just don't know how to input it into the phone.
As for flashing the radio, I've flashed 2, then back to the original. To no avail.
Sorry never had anything like that. I would almost odin back to stock and start over. You dont need root for the sim to work on calls and edge with tmobile.

If you're baseband is unknown don't worry just flash a stock at&t modem and it should go back to normal. Your imei is under a different menu in about phone..the status one.
Also its no ones responsibility to tell you that modifying your phone may break it.

I did flash back to the stock AT&T baseband as stated in the original post.
If I go to About Phone, the Baseband Version is unknown.
If I go to Status, the following are listed as
Network: Unknown
Mobile Network: Unknown
Service State: Out of service
Mobile Network State: Disconnected
IMEI: Unknown
IMEI SV: Unknown
I've backed up the EFS that I have no just so it doesn't degrade further. I'll try to flash again and see, but I still think the EFS is borked.
I'll see what I can, but I think I'll the EFS is borked beyond flashing it to normal.
My point about the EFS back up is that most ppl here don't seem to know what it is. It shouldn't be that foreign of a topic since flashing a radio is obviously problematic for some. I've seen other posts concerning no IMEI after flashing radios on forums other than XDA. It's odd that it's not mentioned as a sticky everywhere.
Backing up EFS would solve a lot of head aches from unlocking / radio flashing woes. I'm hoping this info will save a few people a lot of time and money.
After more digging, I came across this thread:
http://forum.xda-developers.com/showthread.php?t=1646326
Synopsis: Basically, he followed the same guide I did. The only difference is that I flashed the radio while using a stock AT&T rom. Once he flashed back to GB (saurom), he gained back his baseband / IMEI.
This is what I cannot figure out:
CWM will see and flash any radio file I push to my note. If I push a stock AT&T rom, it won't see it. If I put the rom in it's own folder, it seems the rom, but states there's no files.
Is CWM corrupted? Why would it only read firmware to flash radios, but not android roms? Should I just go back and install CWM?
I've searched all over & used google, but I can't find a thread discussing this.
Fixed.
This problem has nothing to do with any of the radios corrupting the EFS folder. Albeit, it's always a good idea to back it up.
Flashing back to AT&Ts stock rom (2.3.6 or 4.0.3) never fix the issue. You will always be stuck w/o a radio, at least from what I've seen. Even flashing back to the stock radio fails. I don't know if it changes the EFS, but AT&T's rom does not like it and shows no IMEI & a bogus SN .
I had to go back, flash to saurom and a compatible GB (or beta T-mobile) radio to get te work fine. ICS radios work fine on ICS.
Saurom and GB radios dont work in my i 717 trying to connect to wind. I got a CM 9 ICS build and ive tired a bunch of radios. they all failed. i keep getting no sim errors. I can see the operator but when i select it it times out and says it cannot connect to the network at this time. it also says interset sim. Im positive it is unlocked.
Modems(radios) or basebands should have nothing to do with whatever rom you are running. Whether they are GB, ICS, or JB modems, they should all work to a degree, at least for phone call ability. I have flashed many different radios trying to get the best function of my att note on t-mo. The best I got was using the Blaze modem. That got me 3g hspa.
The worst will be just giving you edge speed. My note is unlocked and has been on JB running blaze ICS modem working fine. Maybe you need to start over, evaluate what you have, and go from there. There are great threads on att over t-mobile. Good luck.
I picked my rom, and started flashing 5 or 6 radios, and found what one worked best on t-mo.
Presently, I have switched back to att- sort of- straight talk. I'm not thrilled with the speeds. No higher than 4 mbps DL, and 1-1.5 UL. Thinking about going back to t-mo and dealing with the slow UL speeds. I'm on an ICS rom with the ucle6 modem.
Also, flashing a rom does not change your modem. You have to physically reflash the modem you want. Some modems show up as unknown under the baseband. Blaze is one of them.
Another thought- sometimes a reboot will get your sim recognized by your phone.

This is yet another case of the "no sim" bug ....
Damn I wish we could find the answer to this issue, but none exist .....and for some users the return to complete stock even fails to recover service ..

Really what an incredible unlucky glitch.I got my note for only 360CDN good condition but missing the stylus, even still it was a good buy. I'm on Wind mobile, T-mobile here in Canada. I even gave it to somebody who's done a bunch and they ran into the no sim problem. I guess I'll be going back to my HTC HD2 and sell the note .
---------- Post added at 11:48 PM ---------- Previous post was at 11:44 PM ----------
So just to confirm I have followed the process correctly over 20 times and no matter which cm9 cm10 based rom and any ics or gb based radio will allow connection or recognize the sim to the 1700 aws network. With a cm9 based rom I can see my network, but it will not allow connection like the phone is locked, even though i have unlocked and tested the phone on other networks.

Yes, I have the same 'No SIM' issue with a working WIND SIM. I've tried everything, multiple Radios, multiple ROMs. Very strange problem. I wish we had the tools that the SGSIII has for dumping and restoring the NV ram. Even stranger, I do have a the correct IMEI number in Phone, About. I have a feeling it's something to do with how the phones were carrier unlocked.

I have made a backup of the EFS folder with EFS Pro. I tried restoring the NV ram from .bak but there was none found.

It has nothing to do with your unlock. If you've followed the steps and are still having no sim issue you may have to get a new 32k sim card from wind the older ones won't connect in a phone with lte

Had to replace the TMo SIM card with a newer one today. Solved the problem of "No SIM".
I know this is old
I have the same problem with "NO SIM." One day i flashed so many things to my phone and one time i turned it on i got ATT on the top right corner and everything was good. I made some phone calls and texts and even browsed the web. I restarted the phone to check if it was just a fluke and it was. Ever since then i cannot get it to read my phone, but i know for sure the hardware works.

[Q] Manual network selection disabled.

New S3 on UK Three Mobile.
I have an issue that mainly only affects N Irish users I suspect.
Just bought a 3Mobile S3 and I love it. However on 3 firmware, network selection is locked to automatic. I can manually change, but the phone sill change again of its own accord if the signal I chose isn't available.
The reason 3 do it is so that if 3 isn't available, the phone will roam onto Orange's network as a backup. That's all fine if you're in mainland UK! If you're in N Ireland and near the border, you will frequently roam onto Irish networks and run the risk of charges for receiving calls.
Last time I had an android phone I got the firmware flashed and this solved the problem. So far, I rooted the phone and installed a custom Rom, Omega. This didn't solve the issue. Am I missing something? Does installing the Rom not also flash the firmware? Or do I have to try a different Rom?
Going to try a stock firmware from here now. Any other advice would be greatly appreciated.
Nobody?
Installed the stock unbranded firmware last night, plus side was the network selection issue is now gone, but the down side is that it seems to have removed my root access.
I I root it again using the threads here, will that overwrite the firmware again?
Flashing a Samsung-ROM will revert all your changes (including root access) and replace the modem. I've heard that Three has it's own modem which works better than the standard on their network, so you might want to flash it (=the modem, not the firmware) on your phone.
Rooting a phone doesn't make you loose any data or change the ROM. Just use CF-Root and you should be good to go.
Thanks. Already used c.f. root again and all is well.
Any Idea where I can fInd the three modem?

im curious to know too... i've installed a unbranded official rom from three's branded one and if the modem is better i think i'd want to install that too
Every modem has it's own name, so try getting the name from someone who has a stock '3' S3. Then you can google it.
I'm not sure though if they got their own, I _think_ they do
However a network-specific modem must not always be the best.
I've got nearly double throughput over here with the exotic ZNLF2 modem. (Afaik it's Hong-Kong)
So trial-and-error is usually better than just keeping what it was shipped with

[Q] Radio problems (Vodafone NZ)

I run CM 10.1 on my phone, which had original specs: PDA:KG3 / PHONE:KE7 / CSC:KG1 (VNZ). I've been running those CM nightlies since about November 2012 with few problems, updating to new nightlies every few weeks to a month. I'd never flashed new radios - just the CM rom.
Starting a couple of months ago, I began to see a problem where my phone would drop cell service (no bars + empty triangle in the cell signal indicator) and rebooting was the only way to bring the cell signal back. This happened every couple of days, so was bearable. I figured something in the nightlies had caused a weird problem and that the CM devs/community would find and fix this.
After flashing a nightly last week, my phone wouldn't hold cell signal for more than an hour - sometimes not even that. Reboots fixed this but never permanently. I started to read about radios, modems, and RILs. hawkerpaul's post here was a great help. I found that my phone had the original KE7 radio but had a RIL of I9100XXLS8(2) - I presume from the CM rom? I flashed some new radios and have now gone through a series of the (matched) modem + RIL files in hawkerpaul's post above. In most cases I see the following behaviour:
Phone successfully finds network (Vodafone NZ) on boot
Trying to manually select a mobile operator fails (error when searching for networks)
Unable to successfully call out! Dialling stalls, and I can't hang up - only fixed by a reboot
How do I fix this immediate problem of not being able to call/receive calls? Seems like maybe I'm using a radio that doesn't work with Vodafone NZ - but I haven't seen any posts on what DOES work well with that network. I have the modem file to flash the original KE7 back again, but what should I do about the RIL file then? Not sure I have found an RIL for KE7 yet in my travels. Any help would be appreciated - and thanks!
To help me figure out where I went wrong, do the CM builds include the RIL, or is that something that could only get updated somewhere else? I know the rom doesn't change the modem but I suspect that XXLS8(2) RIL had to come from CM.
1) Don't mess with RIL's (You'll make it 'worse').
2) Check stock roms released by your telco. Find out which modems were bundled with those stock roms. Try those modems. If they don't help, look for stock roms released by other carriers which sold the the I9100T world-wide (check Samfirmware). Try the modems bundled with these roms. If they don't help, try any & every modem you can get your hands on.
If you've already flashed RIL's, you may well have created a bigger problem for yourself. You might want to do a clean install of stock as well for good measure if that's the case. The reason I stopped using CM9 (and never bothered with CM10) was similar issues that seem to have gotten introduced with a particular nightly & never went away (a fix was tried which benefited a very few problems who were having RIL problems but created problems for even more people who previously had no problems).

I'm just about at this point. If I reinstall stock, will that reset my modem as well?
Thanks for the help - looks like I did definitely make things worse.
You'll end up with whatever modem is bundled with the stock rom, so probably use the most recent released by your carrier, then you can try other modems released by your carrier as per my PP. The rationale with that is you'd hope your carrier has tested the modems they bundle with their stock roms so they work in most places/at most times with their network. Doing a clean install of stock should fix anything funky messing around with RIL's may have done as well.
If you get no joy from those, proceed as per my PP (You might get other suggestions from other people as well).
Thanks for the help. I was able to flash the latest stock rom, which included baseband I9100XXLS8. This worked fine for making and receiving calls. I lasted a couple of hours with that stock Samsung firmware before I started to get itchy for Android 4.2 again, so I've now rooted and am going to try CM10 again, but at least this time I know not to touch the modem - and I'm confident I can get back to stock again if I have any problems! Many thanks!
Glad you've got connectivity back You can flash modems as much as you want, I'd just be wary of messing with RIL's unless it's as an absolute last resort (I.E you have no connectivity & you've tried every single modem. Too many people try them when their connectivity is fine in the mistaken belief they're going to get 8Mbps instead of 7.8Mbps downloads, I.E it wasn't broke in the first place), even then a clean install of stock & choosing the right modem will often fix the problems.
You're welcome Any dramas post to this thread again & I'm sure someone will help.

Hi and thanks in advance. I have a galaxy i9100 which shows the following information: PDA: i9100xwlsd - Phone i9100xxls8 - Csc i9100vnzls9. I installed via odin Android version 4.1.2 which made the phone work really well except that it kept dropping network service and signal strength. I replaced the sim which did seem to help but did not fix the problem totally. I also notice that the GPS will not find any satellites and just keeps searching for as long as I would let it. I have read various threads and it appears that this may be a modem problem? I have found that Vodafone NZ has released a modem which is i9100xxls9? Should I flash the modem file only in Odin and do you really think this would fix the problem. How would I flash the modem file. Would I do this through odin? Any help gratefully received.
Yes, first step is definitely to flash the modem which was released by your carrier for your region. If you can find a file which is Odin flashable then yes, try it. However most of the files are for flashing via CWM. Are you rooted? If not they won't work for you, in which case you'll have to search around for an Odin flashable version of LS9.
Just to check, you do have an i9100? Not an i9100t etc? Some variants require different modems.

Thanks for the response. How do I know if a file is odin flashable? How do you flash via cwm (whatever that is). You can see I am a little bit or a lot of a novice on this. The unfortunate thing is I enjoy it. I think the phone is rooted and it says the phone is: Model GT- i9100. The phone was purchased in UAE and I have flashed the android 4.1.2 which was a vodafone NZ system. Everything works fine except the GPS and the phone signal drops out all the time showing no service when there is service? Thanks again for your help on this. I have just found that the phone may not be rooted? I tried to install root manager but it indicated phone was not rooted?
Ok so no offence, you need to do a lot of reading for yourself. Reading is the key to successful (ie without bricking) modification of your phone.
For a start, if you've flashed stock then of course you will not have root. You don't need to have root to flash a modem. Have a look here:
http://forum.xda-developers.com/showthread.php?t=1656005
I'm not saying to flash that modem file. But that's how you do it, now you just need to find your file and flash it.

# I'm using P.A.C Rom
# Cleaned cache/delvik and done factory reset. But problem still there
# IMEI is correct but serial number is 'unknown'.
Have you tried restoring a nandroid? I'm also on PAC atm, and haven't had any issues with signal.
Else, try a clean reflash of the ROM.

It worked well before. I don't have any previous backups. Yes i tired re-flash as well. Any other solution ?
Suddenly i noticed network is connected and received a SMS. But when i try to take a call it went back to "No Service".
It could be because of incompatible RIL and baseband. Did you happen to change these recently by any chance?
Don't flash any ril if you're on 4.2. Ril is only ok if you're on stock.
What you can try is to flash the stock ROM for your country /carrier. See if the problem persists .
And just a word of advice, always have a backup ready to go.

Flashed official firmware with Odin. But problem still exists. I noticed strange thing. One of my SIM cards working on it. But 2G network. Sometimes shifts to 3G but can't hold also signal strength is low. When i put other SIM it says Not registered on network (cant manually register even)
Did you definitely flash the firmware released for your carrier & region? Sounds to me like you may have flashed firmware intended for another carrier or region.
Try flashing a few modems. Look at which modems your carrier released for your region, start with those. Then, move onto o re her local carriers etc. If you still don't have any luck, go all our and flash whatever modem you can get your hands on (make sure it's compatible first obviously).
It may sound like a lot of work, but unfortunately there's no quick fix for something like this if flashing stock didn't work.
Oh wait. If you did actually flash a different stock rom, flash the correct one first. If you did get the right one first off, start flashing modems.

Ya. I flashed correct firmware. I'll try some more custom ROMS as well. With this ROM i can get 3G and 2G networks. Data also working. But signal is low. You think its a modem issue ?

[Q] Very Slow Mobile Network, Kinda Strange.

Hello everyone, first of all I should post this to Android Development section but since system tells me I do not have 10 posts, I thought I can post this here.
Well basically I was using Disaster ROM for my SGS2 (International) (I'm in Turkey), and I wanted to use Biftor Rom which was actually KitKat and I didn't know that I should install CM 10.2 or newer first to install other KitKat Roms. So I actually softbricked my phone I was only able to go into download mode. So I flashed my phone with stock 4.0.3 using Odin. But I realised that my mobile network was actually slow as hell. Sometime it can't even connect. But I was like "Oh anyways, it will go away if I flash custom rom". But it didn't. I checked my IMEI and it was there, valid. I flashed my phone 4 or 5 times more with different ROMs. But no luck.
Then I heard an app called GetRIL, because someone told me that my baseband/modem thing might be corrupted. When I opened the app I saw that it says "Unknown RIL". So what should I do? I tried setting APN manually, then automatically by my Vodafone Service. Nothing happened, still same. I do NOT want to send this phone to Samsung Service, what should I do about this situation?
Some Details : My WiFi works very well, I can call other phones, I can send messages, I can recieve calls and messages, Only thing is Mobile Data So Slow and sometimes when I turned data on it says no signal for a while. Help Please !
EDIT: Stock 4.0.3 was only PDA file. It wasn't like 3-4 files to set into Phone section, Pit section... It was only PDA. At the moment I am using BeantStalk Rom 4.4.2 KitKat XXLPS Baseband.
Thanks in advance.
Regards.
If you'd posted this in a development thread, you likely would have copped a slap (and quite rightly). Dev threads are for development stuff, not for n00bs having
problems with connectivity.
It may not even be a phone side issue, it could easily be carrier-side. Having said that, you need to try different modems. Plenty of CWM flashable modem packages on XDA you can try. Start with the modems bundled with stock roms released by your carrier (you can check these at Samfirmware, if you click to download a stock rom, it will tell you the baseband, you can then find CWM versions of these modems on XDA), test, if no better--->>> then try modems bundled with stock roms released by other carriers in your country, test, if no better--->>>then try other modems bundled with stock roms released by other carrier in other countries.
Thanks for the suggestion, today something strange happened and the signal "thing" started working somehow and i can use mobile network, but after phone calls it just disconnects for a while then reconnects again. It doesn't look so annoying so I will deal with it for a while. If it gets so annoying or goes into some crashes and other stuff I can apply what you have suggested.
I read some articles that saying XXLPS Basebands are actually not that well, If I try any other modem/baseband "thing", will it brick or something ? Or can i use 4.1.2 or 4.2.2 modem on KitKat ?
