No 4G in ICS roms? Help! (SOLVED)

    I got a Spectrum back whey first became available in 2012. Recently, past 5-6mo, I've rooted my phone, and using CWM "clockwork recover?" . Since then I've flashed various GB roms, Eclipse, Breakout, BlackPlague, and BlitzKrieg. Each had their uniqueness in issues. But all worked rather well.

    Since the ICS OTA update became available, I've been trying to update that to my phone. While the ROM flashes just fine, I cannot get 4G to work at all. I've tried the Eclipse and ICY Fusion ICS roms. In either one, can never get 4g to work. Also, in both, after I flash either rom, I go to update my contacts by syncing my google account on my phone. Without fail, my phone only lets me do that with wifi enabled and connected. It can't connect under 3g. Same thing for Google Play, can't connect unless I'm on wireless. So I just restore my latest image of 2.3.6, currently BlitzKrieg. And all is well in GB land.

    So here is what I"m doing in each flash

    1. reboot into CWM recovery, factory reset my phone, wipe delvik, and for measure, wipe bat stats.
    2. Install my ICS .zip file from the SD card
    3. Fix Permissions after the install & reboot

    Phone comes up normal like it should. Once its booted, its already activated. I can dial out, receive calls, send txt msgs. But the phone is still stuck in 3G. Data is enabled too. I've tried the #*#*4636*#*#, and that does take me to the hidden menu, I can select LTE-WCDMS-EVDO, but does little good.

    Now, if I'm ignorant, and this is a known issue with all ICS roms for the spectrum, then forgive me for not putting 2+2 together. But I'm flat out of ideas. I dont' have the original GB OS, otherwise I would just flash back to stock, unroot, and apply the OTA update. Then re-root the phone. My GF has the same phone, all stock, got her OTA update, 4g works just fine on it.

    Any help would be appreciated.

    Did you take the official ICS OTA? Or are you just flashing the ICS roms? If you took the original OTA, then flashing the cab and starting over is probably your best bet. If you haven't taken the OTA, you will definitely want to flash the cab for ICS. Here's a link.

    At first, I did the OTA ICS. But by which point my phone was already rooted and running BlitzKrieg 2.3.6. So no stock rom was present at the time of the OTA download. And naturally it failed. So using clockwork recovery, I flashed back to my most recent BlitzKrieg backup.

    Since then, I've just been pulling other developers custom GB and/or ICS roms, downloading them to my laptop, transferring to my phone, then flashing with Clockwork Recover. Its only the ICS that fails the data connection and 4G.

    So if I understand you correctly, the ".cab" applies if I haven't the OTA update then? Meaning I can apply it now, and then reattempt the OTA? Just a note, my CWM is working fine. Not stuck in any boot loop, not even after ICS was flashed. So far, flashing and restoring have been a breeze

    What the cab does, is basically apply the ics ota no matter what you have installed. It will completely wipe your phone and when it's done you will have official ics. Then you can unlock the bootloader with the pwnage tool and start flashing ics and jb ROMs without problems.

    The official ICS update (OTA or stock cab, not a custom ICS rom) has updates to the radio, so that might be causing your data woes. Flash the official cab using this link or the one ortrigger posted. You will lose cwm and root.

    After that use the pwnage tool (link) to re-root and unlock the bootloader so you can flash custom roms again.

    Finally, go get cm10 or aokp41 (link) and enjoy the awesomeness of it.

    Edit: Dang, ortrigger beat me to it.

    your problem is simple. You never took the official update of ics which replaces your radio files. Just flashing the ics roms doesnt replace the radio files. But you do have an easier solution than using the cab method. On the forum here you will find a thread about returning to stock using CWM. All you need to do is download a copy of V6 stock and put it in the cwm backup folder on your sd card and then boot into recovery and restore stock v6. You will also need to get the file to flash stock recovery which I think you get in the thread as well. You must have stock recovery in order to take the ota for V7.

    The cab method would work as well but it's not as easy as flashing a backup in cwm in my opinion.

    Make sure you go to v6 and stock recovery and take the OTA, there are actually two updates, v6b which updates the radio, and v7 which gives you ICS. Once you get v6b activate your GPS and use maps or another app so it gets a lock on your position, else you "might" not have GPS working when you go to ICS.

    Please read the ICS problems thread before you start the process, nearly every problem you might have is listed there, and how to avoid them, and even how to fix some of them, if you fail to avoid them.

    Well I've tried both links for the cab files, both rootzwikki and here. I thought it might of been my work intranet interfering. So I had someone off our network try it, same thing. Plus I get a page saying "forbidden" when trying it with with my phone.

    Are those .cab file links active?
  10. reeseboy

    reeseboy Android Enthusiast

    Which cab file are you referring to? I tested the v7 on rootzwiki and it works, then I tried the v6 cab in the return to stock thread and it worked.

    Interesting. Yeah I tried them all

    When using Chrome, just gets a error:

    Oops! Google Chrome could not connect to csmg.lgmobile.com:9002

    Try reloading: csmg.*lgmobile.*com:*9002/*swdata/*WEBSW/*LGVS920/*AVRZBK/*VS920ZV7_15/*VS920ZV7_15.*S7_15.*P58014.*R5.*cab

    When I try in IE, just says page cannot be displayed. I had someone off my work network try the rootzwikki, looks like he can download that from outside my network

    I've seen that caused 2 ways - a firewall with content filtering and dns server issues. I wonder if changing your dns server to google's will help... That would be for the dns server.

    yeah its my work network. Unfortunately the security is locked down here pretty good. A work around, having someone download the 7.0.cab for me, sticking it in a dropbox share, and I can download it from there...... Technically should work :rolleyes:

    You could try my website... I have the cab files there.

    Thank you Finndo. I think I came across your site once before cruising the forums here. I'll look-up the cab files on there and give it a whirl.

    Well got the version 7.cab. Loaded just as the instructions said. Have my phone in download mode. Downloaded the LG USB drivers, and Utility Tool. Ran the KP500-Utils-EN as Admin.

    Got the expected menu prompts. I put the path information in accordingly, then received and error immediately, followed by the LG Utility, with a bunch of ?????? in it. No actual words, just a bunch "?" instead. the Dos prompt is still running in the background saying loading. So now I'm stuck.

    maybe the source .cab is bad? I tried to take a peek at the contents of that file in explorer and all it says is

    Can not open file
    as archive

    Just a FYI, the phone is fine. I Ctrl'C the process. Closed it out, pulled the battery, rebooted the phone, all is well with the old ROM still. I'll try it again tomorrow on my personal PC, not a work one.

    Was the cab in the same folder as the lg tool? That's a big one; I can't get the program to work unless the cab is in the same folder as the rest of the files. (tl;Dr if you answered that already)

    Also, I generally run those from the city drive, not a sub folder... It seems to run better.

    Well after working 10hrs on a afternoon shift, it takes me a little to understand the simplest of things....:eek:. On that note, I went ahead and and downloaded v6_stock_noroot.zip + the recovery file. Flashed with CWM, installed form the zip, got my OTA updates, and now on ICS with 4g. It a beautiful thing now...................

    Thank you to IMUCarmen, and all others here that helped me out with this. Phone is working great now on ICS.
