[Q] No 3g after several changes of rom with Odin - Galaxy Ace S5830i Q&A, Help & Troubleshooting

Hello, I changed my rom several times with Odin, and now I can't get 3G signal, just "G", not even an Edge "E".. I tried a lot of roms after that, roms from sammobile for my mobile operator, any tips to solve that?
Thanks!
#Edit
For some reason, after I installed a deodex room (gt-s5830c_zta_vjlb3-deodex_rb) my 3G started to work again.. but if I just change the PDA, it stop.. Wasn't supposed to PHONE be the file which make the 3G work or not? This VJLB3 is an old version of my operator, when I got the newest version the 3G did not work.. fml

Are you absolutely positive that your 3g was not related to service operator when you were on the stock firmware in question ? Have you tried your SIM card on other phones to confirm the functionality of 3g network ?
Did you check you APN settings :
Dial "*#*#4636#*#*" > Phone Information >Set preferred network type > WCDMA preferred Does it set correctly ?IF not then choose wcdma; press turn off radio then press turn on radio; press home button(not back button). You will get 3g. If not then reboot.
Have you lost your IMEI ? what you see when you dial "*#06#" was it gone on your last non - deodex fw ? what is your phone variation ?
what was your last CSC/PDA/MODEM part , which does support your base band/3g and other things , before you lost it ?
Your country / Region and carrier you are staying too please ,, we might need to flash the only Modem part over Odin to resolve this issue according to instruction i will provide . However you need to be more specific by providing more details such as name of possible custom Roms you did flash. stock CSC/PDA/MODEM details you did try and other minor details will become valuable in this troubleshooting .

Hello, thanks for the answer, the same SIM card worked on with 3g with the deodex rom, and wasn't working before it. I got no 3g with one rom, changed it to deodex and got 3g, changed again and lost, all of this in a few minutes, so wasn't problem with the operator or SIM. I didn't check the APN, I just downloaded an app from my country to try to set it. I don't know if I did lost my IMEI, I have it wrote in the back of phone, but didn't check if is the same after all that changes (and if is possible to change it), I changed the rom a LOT of times, first times with CWM and after with Odin, with the I variation, C and M (trying to go back to original stock). I think the original firmware was an old version of M variation (S5830MUWHKL4 maybe), my country is Brazil and the operator of the SIM card is Claro, the last stock from sammobile I tried was the last one from Claro, tried with and without CSC after splitfus2 it.

I really don't understand how Deodex Rom has anything to do with your 3g/IMEI/APN settings. Because Deodexing is basically repackaging of your APKs in a certain way, such that they are reassembled into classes.dex files.
By doing that, all pieces of an application package are put together back in one place, thus eliminating the worry of a modified APK conflicting with some separate odexed parts.
custom ROMs or APKs are always deodexed to ensure integrity.
Ok so you are from Brazil (Claro) and on C variation of the device, thus splitfus2 and wipe package troubleshooting is not supported for C variation . (Splitfus2 only generates the normal extraction of CSC/MODEM/PDA parts from your single xxx.tar.md5 file, noting more in this case ). Use this pre- configured app for normal parts generation instead with ease .
This is the list of the correct xxx.tar.md5 for your device and you have tried the last update for your carrier from this page ( PDA : S5830CVJMA1/CSC: S5830CZTAMA1 )according to you , right ? and you lost your 3g support ?
I got couple of suggestion for your 3g :
1- Use 2012 tested Brazilian Multi Package Firmware from this page ( PDA: VJLF3/CSC: ZTOLF1/VJLF2) .
2. Check you got the correct Odin and drivers installed on your system ( Odin3.v3.07.Cooperve.exe ; Drivers post ) .
3- Get into Download mode ( pressing Vol(+) + Vol(-) + Power Keys) :
- -press volume up
-Open Odin3.v3.07.Cooperve.exe
-Connect your phone to PC via USB cable.
-Make sure that your phone is detected in "ID:COM" area.
- Put your CSC/MODEM/PDA parts into their respective places . Do not use pit file and Do not tick re-partition though . Factory reset and reboot selected by default >> push the START !
- DO NOT disconnected nor disturb the flashing Nand process , until the process being terminated.
Get into e3 stock recovery and wipe your /data .
Now in your brand new FW :
Dial "*#*#4636#*#*" > Phone Information >Set preferred network type > WCDMA preferred /only and confirmed my instruction in first post has met with your APN settings.
Dial *#06# as instructed in first post ( IMEI box with your 15 diigit number must appear )
CSC is your consumer software customization and it is specified to geographical region and carriers. CSC contains the contains the software packages specific to that region, carrier branding and also APN settings for data connection .
WE can easily change the settings inside our Multi - package we flashed for carrier compatibility etc etc :
Code:
Just type *#272*Device IMEI# at Phone dial pad. For IMEI type *#06#.
Select the CSC that you want.
Click Install.
Phone will be rebooted by itself.
Note –Changing this will factory reset your phone. Do backup before perform this task.
Note – CSC can sometime be corrupt. It may lead to infinite loop. Reason unknown.
report your progress please for future reference ,, Thank you for reading this mate ,,,,,,,,,,,

Me too, I don't know why the heck just the deodex rom got 3g signal, I flashed the same PDA version, but no deodex, and there was no 3g..
Originally my Ace is an M variation, I bought it unlocked on the internet and came a 5830M, probably with S5830MUWHKL4 rom.
Yes, I got that rom from that page and used the splitfus2 on it. I'm waiting my dad get back from work (I'm trying to do the best fix on the phone so he can use it without problems) to start trying again to put the last rom with your instructions. Also, do I really need to flash CSC? This part comes with a lot of trash apps that is impossible to remove by normal ways, and I don't want to root the phone and use 3rd party programs do remove that things.
Thanks!
#Edit
Also, the PDA from deodex rom has 431mb and the PDA of nondeodex has 185mb (same version of rom), is it normal?

Yes you need your CSC as i have explained it in details ,,,and you have too get root privileges for any removal of your system apk's ( If you are under some sort of warranty , you can use UN-root script or galaxy toolbox to reset the counter to zero for avoiding detection i guess,after you have done playing around with phone ,, rooting and using either manual or script method is recommended for bloatware removals on Odex roms , third party apps like disable service and TB is also advised ). Or Deodexed your Rom and remove bloatwares , but you will loose ~70 MB of your precious internal storage ( link2sd or Universal Cronmod could fix the storage problems ) and PDA size you did mention is quite natural .
Still waiting for your final report mate ,,,,,,,
