4G FIX after doing a radio update

Hey everyone,
After I did the radio update (after doing the full root) my 4g was really messed up. The 4g would just not stay on and kept going out and then coming back every few secs. I tried reflashing the radio and yes I also formatted the cache right after and going back to the old radio. Then I tired going back to stock and it was fixed but when I did the full root again without the radio update after, well the 4g was back to crap. I even tried a custom rom after the root and still no go. So after doing many tests I found out that the firmware for the wifi is different from stock and full root. I found this out by going to ##DEBUG# then WiMAX Engineering...The full root had 20100401 (im guessing its the date of the firmware) and the stock had 20100423. So after more testing this is what worked for me.
1. I took the image file from the first part of the root (PC36IMG.zip)
2. Then I extracted android-info.txt and wimax_25043_R04.img
3. After that I made a new zip file with those two file from above and named the zip "PC36IMG" (without the quotes).
4. Then I put the PC36IMG.zip on the root of the SD card of the evo.
5. Then I booted up to the bootloader (u know the screen with the androids skating). Then I did the update and reboot.
After that my 4g was working without getting droped every 5 secs
If someone else tries this please let me know so I know that I didn't just get lucky.
P.S. IM NOT RESPONSIBLE IF ANYTHING BAD HAPPENS (it shouldn't but hey **** happens lol)
Enjoy your 4G back!

I have the same problem, but...this is a hell of a first post. Anybody wanna test this out.

If someone can post the files, I can test it. I'm at work right now and can't download files that big w/o being flagged.

you mind posting the update zip you created?

I don't think it has anything to do with the ROM.
If when you are connected to 4G you can access the internet, only suddenly 4G it drops for no reason and switch to 3G and then reconnects to 4G and goes on and on, below is the solution. if when you are connected to 4G you can not access the internet at all, the below wont fix it for you and it is probably a problem with your rom.
You will need your msl code to fix this, loop up in the forums to to obtain your msl code from Sprint:
hit ##DATA# > Edit mode.
Put in your msl code
Chose WIMAX
Scroll down to Wimax_Idle_Sleep
Change the value from 10 to 300.
Click menu, commit changes and restart the phone.
This fixed it for me and i never drop 4g (when in good coverage) again.
Basically Sprint has some STUPID setting that tells 4g to go into "sleep mode" of no data is passed on the 4g connection after 10 seconds which is essentially disconnecting 4g.
The problem is it goes into sleep mode (disconnecting), but then rescans and look for a 4G signal > reconnects to 4g and if no data will be passed in 10sec it will do the same again in an endless loop.
10sec to put a connection into sleep mode is really low so change it to 300sec.

This sounds like the same issue. I wonder if that file sets the sleep time? Just a guess. I had the same problem and this fixed it.
Here is the thread where I found it.
http://forum.xda-developers.com/showthread.php?t=704845&highlight=4g+sleep

Oh for me the wimax idle sleep time was always 10 even with the 20100401 firmware. The only thing that seemed different was the wimax scan attempt time. In 20100401 firmware it was 120 and in 20100423 firmware it was 1. So when I tried to change it in the older firmware it said I can only do 5 - 300. So I tried 5 and still no fix. The 4g still drops in and out. Here is file I used.

Tried your .zip. Not good. 4G is stuck on scanning and won't connect. I'll see if going back to the stock radio will fix it.

Oh that didn't even happen to me but I was already on the old radio. Try the old radio and remember to clear the cache. If it gets stuck then go to ##DATA# and check your wimax settings. Let me know how it goes.

Ran back through the Simpleroot process and got 4G back. Whew.

Nice! I wish I knew exactly what causes this problem but hey if it gets fixed then I don't care so much lol

is this zip already modified??

All that zip has is the wimax radio file to flash it but the file is old now. If your already on the latest radio then i would not use it because it may cause problems.

im stuck in "scanning"

You may need to reflash the radios and wimix. Are you on 2.2?

im on original 2.1 update1
I have the newest baseband tho... 2.12.00.07.28
I flashed this zip and phone is acting a little goofy
3G is in and out also!!

is it possible i may have to reflash the original RUU and start from there??

Why don't you try 2.2 maybe it will work after that.

after i just installed that zip im now getting DATA call failures error code 67.

Yea that should fix it or see if there is 2.2 RUU file out. Sorry I'm not home so my responds are very slow lol.

No data connection after rooting to custom rom (Darky's v5.6)

I'm new to flashing custom roms and what not. I used odin and flashed everything to the point, csc, modem,pda,pit the rom works awesome but i cannot for the life of me connect to the internet. the 3g icon or h icon wont' show up. in the status it says my network type is gprs and i'm roaming and my mobile network state is disconnected.
I'm with fido, the phone is unlocked i have never had trouble with data or anything until i flashed to a custom rom.
Anyone have the same problem or suggest how to fix?

Data Conn. Issue
Hey mate,
Have you gone into 'Settings', 'Wireless and Networks', 'Mobile Networks' and then 'APN settings' and entered your appropriate settings?
That should fix it if you define the correct access point.
Alex

hey man, yeah i did all that stuff, went in there, found my carrier, put in all the apn settings i can find and still nothing. when i put data roaming on then i get data and the edge icon comes up.

Hey dude,
That sounds strange, flashing custom (or even release) roms is never a guarantee especially with weaknesses in the way that ODIN communicates with your phone, What I would do is Re-Flash your stock rom through ODIN then use the "quick" install method from Darkyy.
I am running 5.6 like you, and I had issues doing it through odin (I kept getting random FC's), additionally, the rom; if installed from CWM will keep your apns and apps e.t.c. along with many settings and configs from the base rom you're using before the flash.
That is the best advice I can give you.
Alex
My config is a follows:
I9000 International
16gb SDHC
500HZ Hardcore Kernel
Darkyy 5.6

Whats the process for reverting back to stock 2.1 eclair rom?

Did you keep a record of your firmware version before reflashing?
If not, you may have to ask someone on here what your base firmware was.
Are you familiar with using ODIN? (The software used for reflashing)
Alex

I am having same issue to...I used 5.4 from Darky and it works well...same with DocRom 4.0 works and the next 5.1/6.0 don't work.
Both Darkys and DocRom are based some JPX....which seem to be root cause..

I've have the same problem. Tried eveything but still didn't work. So went to Samsung Service Centre to have my SGS firmware refresh. I notice after the refreshed same issue of data com missing. Told them and they when into the SGS to select the telco operator setting selection. Now data com. working well. Anyone know the SGS handset setting code? I want to reload to Darky's v5.6 again.

hi folks
i have the same problem... my provider is a virtual provider in the network of our biggest provider here in austria. i was using doc's rom based on xwjpa firmeware and everything worked fine without enabled roaming options.
since doc's rom is based on the newer releases (xxjpx, xxjpy) i' only able to use data connection if i turn on roaming. it also shows me that i'm in a roaming network. i guess the cause are the xx firmwares. xw and xx are european firmwares but i do not know the differences between them. maybe someone has more information about the differences? currently i'm using xwjpa firmware because i don't want to use my phone with enabled roaming options.

hey um i'm having the same problem and thought replying here would be better than starting a new thread.
well i installed the rom without having any idea of what i was doing *stupid idea* so i didn't take note of my original firmware.
i didn't use odin to install the rom just clockwork recovery and the rom and everything installed fine except my data network. i can get signal, call, receive the only problem is i get no data transfer. any help much appreciated. if anything can someone help me step by step to reboot my phone to original?

just for future travellers
Sadly this isn't my own gem, but yeah. hold the power button down, wait for the shutdown menu, above the airplane mode there is a data network button, and it'll most likely say "de-activated" if nothing else has worked. Its ok to feel like a chump, I did after rehashing the hell out of this phone for a few days ( the wifes phone, my phone does exactly what its told. )
Anyway, yeah, this will probably be the reason for the lack of the icon "G", "3G" or "H" where it should be.
Dave.

[Q] Please Help. Very strange problem with my phone.

Hello,
I'll start from the beginning so maybe someone can figure out exactly whats going on with my Galaxy S4.
So my carrier is Telus and I had just a rooted 4.2.2 and everything has been fine since day 1 of rooting. 2 nights ago I noticed the stock Google Edition ROM was out and I decided to give that a try. I flash the 4.3 Google Edition ROM which said Canada (Bell/Telus/Rogers) and I was using that for about 24 hours. Everything was great, however I noticed I lost my 4G/LTE connection. So without being connected to WiFi I had no data plan basically, everything was on, carrier was selected all the APN settings were correct so I was lost. Completely confused as to why this is happening I just decided to restore to stock, unroot and start from scratch. I used Oden to restore the stock ROM from Telus back to android 4.2.2
Now, once that came back, still the same problem and what I noticed was it installed all the Bell Mobility stock software and when I plug the phone into Kies it's listed as a Bell Mobility device. How is this possible? I used the Telus stock ROM to restore, once that I've used before without any issues at all.
Any help would be appreciated, if you have any questions let me know.
Thanks.

I'm wondering if the 4.3 rom managed to update your EFS or CSC data... I'm no expert in these areas (and I'm on AT&T), so I don't think I can be much of a help. But this might be something to look into. Also be sure you wiped data too (you didn't mention it).
Also, I'm wondering if you have the correct Odin file for your carrier (if there is such a thing as a difference?)? I know with older handsets, it was possible for AT&T to push out APN settings, etc. from the carrier's end, forcing updates to your handset. Not sure if that's still possible or not.
If you have a nandroid backup of your ESN partition, you might try to restore that. Don't try to restore someone else's backup, or you'll mess up your IMEI and such.

Yeah sorry I forgot to mention some stuff. I have wiped data and factory restored before flashing the stock ROM in Odin as well as wiped everything again as soon as its complete. Right when it boots up the APN info is all wrong. I have data now if I set it up myself but its just sitting on H+ rather than LTE/4G. Also it seems to install the Bell bloatware rather than the Telus bloatware, so something within the phone still thinks its a Bell phone. I'm stumped, so is the Telus guy who was trying to help me with it today. I know I'm using the right .tar stock file from Telus because I've used it before. Man this really stinks!
EDIT: I'm not sure if this is valuable info to add but I just noticed when doing a factory reset it says the CSC that's applied and its labelled as BMC which is Bell Mobility. This is a Telus phone so I'm assuming my problem is somewhere right from there.

ALRIGHT!
I fixed it... I found a tutorial on how to change the CSC with the key command
"*#272*Device IMEI#"
Then it showed a list of carriers and I chose the right one, rebooted and it restored everything and presto. 4G/LTE is back on.

GT-i9505 No mobile network/data after flashing custom ROM

Hi guys been searching all day when I can grab some free WiFi, basically I rooted my s4 gti9505 with auto root and then installed custom recovery, and flashed PAC rom. I'm unable to make calls or receive mobile data but can use WiFi. My settings say baseband unknown .. I'll attach a picture of my settings here in this thread. I have attempted to flash a modem/radio in Odin but this didn't seem to make any difference, the problem is I'm not sure if it was the right thing to do (didn't make a back up of my phone foolishly before flashing PAC rom)
I'd appreciate any help with this guys! My network is vodaphone UK if that makes any difference to any advice given...
Thanks in advance!

will do this too, have just finished flashing MGA modem twice using your steps, will flash rom again..i wonder if i should wipe/factory wipe as i would when installing new rom...ill try it!
no luck -still no network. im running out of ideas
network - unknown
mobile network type - unknown
imei unknown
imei sv - unknown
going out now for a while but thought id ask - do you think that installing official stock rom (perhaps from your s4 unrooting guide) would help flashed via odin? from searching i can see that some folk suggest that stock will reinstall everything i need...im hoping so, i really wouldnt mind going back to stock, anythings better than this

did you put modem in "phone" in odin?
hmmm weird! i guess your imei is not corrupted, sometimes while flashing rom in cwm, efs partition is not detected, so flashing modem twice should work
you can try with an other modem, use new one (but im sure to flash it twice)
another option is trying to flash your stock firmware

yes put it in "phone" mode, thats the second or third one i have flashed now so im not sure it wont help but for sure ill try again!
are you able to determine that its not corrupted? would it state as such if it were? im going to flash a stock firmware as a last resort. lost after that haha
edit - installed cwm using sgs4 flasher and re-installed my custom rom and gapps, booted no probs and network now working - sorted!! thanks for your help i dont think i would have reflashed the rom without your advice to do so

So I'm practically in the same boat. I'm currently on P.A.C. man nightly 09/18 (Vodafone Germany branded device). I never had similar problems, but now I can't call (or be called) and I'm not able to use mobile data.
I nearly tried everything:
1) I checked the IMEI (saved it before switching over to custom roms), but an IMEI number is still there.
2) Went back to stock to see if it's a problem of P.A.C. man ROMS or not. On stock it didn't work either.
3) Went back to P.A.C. man ROM and flashed modem XXUBMF8 via Odin 3.04 (from this thread: http://forum.xda-developers.com/showthread.php?t=2192025)
4) Flashed the modem again after I flashed the ROM because it didn't work either.
So I'm completely lost now, I really don't know what to do next. I had mobile data for a couple of seconds every now and then, but nothing stable. And since the problem came up (yesterday evening) I can not make any calls at all.
Can someone help me?
Edit: The very strange thing is that I have full reception balks in the notification area (only in grey). But still, I guess this means that the device is somehow able to detect a signal but can not connect to it?
Edit2: I apparently have no Device-ID. May that be a problem?

So I took some screenshots to show you guys my problem a bit better. For some reason my mobile data now works (currently HSPA, but it's extremely slow). But I still can't make any calls (or get called too). =/
Edit: So to sum this up: the strangest thing about this problem is, that even when I go back to full stock I can't make calls. =/ What could be the problem? An IMEI number is present in the settings (althouh the 'IMEI SV' under 'About phone' --> 'Status' was one digit below the current one that I can see under those stats). The whole problem makes me believe that my provider can't sort my phone number to my device (I'm on Vodafone; but if that's really the case: why the hell does mobile data works sometimes?!). The other possibility: something with the modem/radio is broken. Could this be the problem? The thing is that I also tried to flash a custom modem, but the problem is still there...
I'm really concerned that my phone just became an expensive paperweight

Slightly different than my problem in that I didn't even have any bars for reception..my problem was fixed by changing the custom recovery software (originally I used philz to flash PAC), But I flashed cwm and then used this to again flash PAC, and all was good..don't ask my why but it helped me so you might want to try this...

Thank you for your answer!
You also flashed a different modem didn't you? Did this help or was it only the custom recovery? I'm confused because I used CWM before and never had problems. But then this mess all came up...

Yes I flashed several modems, that didn't help..only using a different custom recovery to flash my custom Rom again helped..hope you get sorted!

So I tried to flash PAC with TWRP 2.6.0 (it worked before), but the problem is still there.
I'm really confused. I really don't know what I can do or try to fix this mess... Is there some USSD code or something to find out if my device is missing some ID codes or if the modem is messed up or something?
Edit:
Update: For some reason I now can receive calls/SMS but only when I'm on GPRS speed. Outgoing and ingoing calls are no problem then. When my device is on HSPA or HSPA+ speed however, the old problem of not being able to call or be called is back. On one hand it's good that I'm somehow able to make calls again on the other hand it gets stranger and stranger. I know that it's a bug on PAC man ROMs that you can't change the mobile data speed options (LTE/HSPA/GPRS etc.), but I think that this could be the problem (or at least a part of it)...

Actually I can change the data in my phone between 3G and 2G (don't have LTE support here in my country)
Have you checked your APN? Think that might be a problem.
Also please post the steps you take before flashing PAC (ROM, kernel, recovery, etc)

Within Wireless & Networks --> Mobile Networks --> Network Mode? On PAC? It always crashes when I try to change something there. In the PAC bug post this seems to be a known bug, my mode is also set to GSM/WCDMA/LTE. But whenever I enter the settings to change this, only 'LTE' is chosen as option. I don't have LTE on my plan and I read somewhere else that Vodafone has major problems with it's LTE network here in Germany and that it may be better for customers without it to turn it off.
About APN: there is definitely something strange. I can enter the settings and I see three different APNs that were not created by me (they must be the standard carrier ones): they are called Vodafone DE (for Germany), 1und1 (pretty strange because the settings are the very same on this one, only the name is different) and Vodafone DE-MMS.
The strange thing now is that I can't change any value of the Vodafone DE APN... When I go into its settings, everything ia greyed out. This was the same on the stock ROM...
Now when I create a new APN with the correct provider settings (found via Google on the VF homepage), the phone still won't work. When I put the device aside for a few minutes, the Vodafone Deutschland DE APN is the selected APN again although I never went back to it...
Is there some option to take a deeper look into the modem stats to see what's the problem?

Install stock ROM

I tried that already, but it didn't help. Same problem...
I factory resetted the phone, wiped cache and dalvik cache and then flashed my Vodafone branded stock ROM via Odin that I had on my device when I got it. Didn't help for some reason... But: should I also try to go back to stock ROM via KIES? I haven't tried this method until now...
Edit: About my flashing method: I went from the stock ROM to rooted (via CF Auto root with Odin). For PAC I then flashed TWRP 2.6.0 and then in recovery factory resetted the phone, wiped cache and dalvik and then installed PAC. After that I installed GApps. I used this method before and it worked without any problems...
Edit2: I found this thread, it appears to be the same/a similar problem with the S3: http://forum.xda-developers.com/showthread.php?t=1805709&page=6
Now is there something similar for the S4? I think I tried calling ##72786# on stock ROM and it didn't work...

Within Wireless & Networks --> Mobile Networks --> Network Mode? On PAC? It always crashes when I try to change something there. In the PAC bug post this seems to be a known bug, my mode is also set to GSM/WCDMA/LTE. But whenever I enter the settings to change this, only 'LTE' is chosen as option. I don't have LTE on my plan and I read somewhere else that Vodafone has major problems with it's LTE network here in Germany and that it may be better for customers without it to turn it off.
About APN: there is definitely something strange. I can enter the settings and I see three different APNs that were not created by me (they must be the standard carrier ones): they are called Vodafone DE (for Germany), 1und1 (pretty strange because the settings are the very same on this one, only the name is different) and Vodafone DE-MMS.
The strange thing now is that I can't change any value of the Vodafone DE APN... When I go into its settings, everything ia greyed out. This was the same on the stock ROM...
Now when I create a new APN with the correct provider settings (found via Google on the VF homepage), the phone still won't work. When I put the device aside for a few minutes, the Vodafone Deutschland DE APN is the selected APN again although I never went back to it...
Is there some option to take a deeper look into the modem stats to see what's the problem?

Delete the unused APNs.
Do you have mobile data?
Also I asume that you're running the latest vertigo's build, because with me GSM/WCDMA/LTE is always selected.

Sometimes I have mobile data, but only for very limited time; for the majority of time, I don't have mobile data and can not make calls.
I also tried to delete the unused APNs, but still no change =/
I tried to use a different Micro SIM in this device, but the same problem appears. No data, no phone although I have grey reception balks.

any update on this one?!

Root gets rid of all radio stuff?

I had an issue with Alliance rom. It went from wifi to 4g and I lost the prl and other stuff (said unknown). I only had wifi.
I was able to Odin back to stock. It took like three times as it would not move past the activation screen.
Now, on stock, I flashed TWRP recovering using ODIN, then used the CF root from Odin also. Phone restarted and while I have the 4g logo, I have no phone and the information is missing again (PRL). I do get wifi.
I just used Odin to reflash stock and it is still doing it. I also used the imei tool to restore what I had backed up (EFS). Can anyone help? What is going wrong?
Edit: Phone restarted with root BUT now I cannot make calls (it says roaming) and I am missing the prl and other things again. HOWEVER, I can use wifi, and 4g and no texting also.
If anyone has a clue I'd like to know, thanks.

I actually could not find the stock modem. I DID solve it.
1.) Odin back to stock. It will freeze on the activation screen.
2.) Remove sim card after shutting down.
3.) It will get past that and connect with wifi.
4.) THEN clock on roaming to turn it on with sim in.
5.) Phone will then contact US Cellular to "activate and program." It will finish after a few minutes.
6.) Restart and enjoy
In case this happens to anyone else. Thanks for the help (lol). I've had a Droid Eris, HTC DNA, and a Droid Bionic.
