My phone has had many differet roms on it(SRE, Frankin-Twiz*latest*, OC/UV Kernel, i9000 rom)
anyway, ive flashed back and forth several times between roms, after finding that i like Frankin-Twiz the most, i decided to do the Voodoo lag fix. It was running fine, then i saw that they released the OTA update for our captivate. I flashed back to FACTORY stock rom with the ODIN One Click recovery tool, and had it back to stock.
Now here is where everything goes to ****....
I clicked Check for update... it was searching, then it started to download... my connection failed with 3g(bad reception in my area) i tried to connect with wifi... and clicked check for update again... it said no update available.... so i figured "oh it may have downloaded" and clicked resume update.... the Phone said it needs to reboot, screen goes black, and NOW IT WONT EVEN TURN ON!!!! HELP!!! ive tried to reboot into download and recovery, but it WILL NOT TURN ON!!!!
PLEASE HELP!!!

Exact thing happended to me (and many others). It seems that if you cancel the download, then resume it totally bricks your phone. I'm going to leave the battery out overnight and try it in the morning before calling AT&T.
Happened to me too. Couldn't do anything with it after so I went to exchange it. The new captivate is... how do I say this. Much worse...
Won't lock onto any satellite (where my previous Captivate's GPS was great), screen looks... odd, and this update refuses to connect to the AT&T servers.
I'm actually getting pretty aggravated right now.
. I flashed the KZ file with lg update software as explained in the XDA thread but I could not get the process to work right. My phone kept disconnecting at 28% and it would not turn on no matter what I did. It would only make a short vibrate as if it was turning on, and the computer would notice it but only for a short time. And never once did a light on the screen, or LG logo, or anything at all ever appear.
I figured I had really screwed it up, but when I plugged it into the wall it booted up perfectly. All my data was in tact and the rom i had flashed through cwm was still there, not the kdz file that I flashed with the lg software.. I noticed that my sim card did not come up as being in the phone at all. I looked in system setting status and noticed that all info related to my imei said unknown. I opened up the mfg app (277634#*# from the phone app).. Under "version info" then "factory version" my phone now says xmm6260.. It always used to say p925..etc... Even after flashing the zip to debrand from at&t this never changed from p925 even when every other aspect of my phone has.. I was hoping maybe once I put in an activated sim card everything would be fine and my phone would be unlocked which is why i flashed through lg software.. But seeing as how other people are having this similar issue and their phones not seeing the sim card, well im looking for some advice.. Should I try and re flash kdz file through lg software again? if i do, im going to do it on my XP computer this time, not Windows 7..
Just wanted to add that I did try wiping data and cache from cm and no dice.. Root and CMW work fine but no matter what I do, if my phone is turned off, i cannot boot up or boot to cwm or boot at all unless i plug the phone into a wall carger and then once its on it stays on and i can unlug.. SORRY ABOUT THE LONG POST, THANKS IN ADVANCE FOR ANY HELP..
I would reflash CWR first and foremost, then try to flash back to stock.
No IMEI/GSM Radio
Hi, were you able to fix your problem? If so, could you please give me a hand, I have same problem.
Im attaching a couple of screen shots, one where you can see that IMEI is not shown and other is where you see the phone number thats on the SIM but has a sign like if no SIM were inserted.
Using the KDZ detects the IMEI, but after flashing it doesnt show up on phone.
Thanks
Took my phone to a cellphone shop and they fixed it. Everything is back to stock and working normal.
Hi ive got the same problem, did you fix it?
Yes, my phone is working perfect at stock. Im going to wait for GB ir ICS with a working 850MHz baseband.
I have been using CM11 (14-03-2014 I believe), without major problems until yesterday. Sometimes my phone seemed to disconnect from my SIM and I had to re-enter my pin code to reconnect to my operators network. But as of yesterday my device doesn't seem to recognize the SIM card, It doesn't ask for a code at all and can't make any connection whatsoever. I didn't change a thing, this problem started out of the blue.
I wiped cache and dalvik, updated to the latest CM nightly (08-05) but that didn't make any difference. In other threads I read about the baseband that might need an update, but I can't check which version I have now because when I try to enter the hidden menu I get the no network connection error. The strange thing is that CM11 has worked with (I guess) the stock baseband.
Is my phone tripping or could it be that my SIM card is broken?
Help and thoughts will be very much appreciated
Try it on stock to be sure about it.
After some searching I found a phone that could fit a regular SIM card, a Blackberry 9900. My SIM worked perfect in this phone, so that is not the problem.
I Also did a complete wipe and installed a stable version of CM 10.1.3, but that didn't seem to help. I hoped that a downgrade would have done the trick. I might try a ICS ROM or the stock firmware, but I kind of lost hope and i'm starting to think this problem is hardware related in stead of software. I'll report back with results on stock firmware and the ICS ROM.
How can I make sure the SIM reader in my phone is working properly?
Sorry for double posting, but I got an update:
SIM wasn't working with ICS so I decided to go back to the stock ROM. However, when I tried to flash V20B.kdz with KDZ_FW_UPD, the program got stuck at wParam=2010 and iParam=210. The phone is now stuck in S/W Update mode, and I haven't found a way to restore it yet. I will argue a little more with my phone when I get back from work, I'll open a new thread on how to unbrick when I can't do it myself.

I have the same problem, and exactly the same error at reflash.
Dead end. Buy a new phone .
I tried to flash it about 80 times. One guy from a gsm repair has a bit luck and make it work at the first, but then, when he wanted to repair my imei, the phone stucked again in S/W Upgrade.
Today I received a notification from supersu pro that I needed an update. After it installed it requested a restart. After restart, there was no connection to cell service nor could I turn the radio on in network settings nor were there any settings registered. I was however able to connect using WiFi from my home computer. I was running stock rom with twrp-recovery and OS h81120o for t-mobile. I tried restoring backups by twrp with no radio/network function. I installed
twrp-3.0.2-0-h811.img
android_device_lge_h811-android-5.1.zip
G4-H811-MM-20i-Stock-Debloated-Rooted.zip
G4-H811-MM-20o-Stock-Debloated-Rooted.zip
G4-H811-MM-20o-Stock-Rooted in this order with nothing different working in network connection and radio off. I finally installed LG-H81120i-Flashable.COMPLETE.zip and it said installed successful yet when restarted the phone bricked. No power on, nothing. I received than same notice for my rooted Samsung galaxy tab 4 8.1 and declined it and am still running fine there. Any thoughts?
Hey,
I was in the exact same boat and almost gave up!
Got my LG back from repair and I rooted it then made a back up, everything was working fine. Flashed a new ROM and updated SuperSU, was not able to get a signal or mobile connection after that. IMEI Number was now NULL. I tried factory reset but still nothing can get the network signal back. Even restoring back to my back up did not work.
I read that if you flashed the LG-H81120i-Flashable.COMPLETE.zip you will brick so I avoided that. I finally found the solution and maybe this will work for you.
Download LG UP and your kdz file (H81120o_00_0613.kdz was mine) on your pc.
Set phone into Download mode by pressing volume up and connect to PC.
Open LG UP and load the KDZ path file and run. Phone should reboot and come back. My signal came back after this.
I hope this method works for you.
Best of luck!
I recently rooted my H811 G4 (T-mobile) and then installed the latest Imperium ROM on it. Everything worked fine for three days. The only thing that kept popping up was an alert from Lookout, saying that the Imperium Settings app had riskware and wanted me to delete it. I just ignored the warning as I figured that it was being fussy over an app from a custom ROM. I also kept getting notifications to upgrade my version of Android but I ignored those too as I learned that with a rooted phone, it either won't work, or will unroot the phone. After 3 days, I suddenly lost connectivity to the T-Mobile network. Could still make calls and text over wifi, but nothing when the wifi was off. After going into the settings, it would say that the network was disconnected. I took the phone to T-mobile and they tested the sim card in another phone, to which it worked just fine. So that told me that something was obviously wrong with my handset. I restored the phone back to factory default and was able to make calls again. Imperium was still installed on it. So I went back into recovery and wiped the phone clean. After selecting to restart the phone in TWRP, I got stuck on the bootloader screen. So I downloaded LG Bridge and got it working again. I was going to wait till I got a notification to upgrade Android before rooting it again, but after 2 days, I never got it. Has anyone else had this happen? I thought Imperium was cool but I'm not thinking of just going with another custom ROM.
