Guys I am deeply sorry if I am going a lil off-topic, but it is a question about this ROM if you read the whole post.

I have been having reception problems running the official CM11 with the p880 and at times where I know there is coverage and my other phone has I wasn't even able to send SMS, I'm pretty sure it has the frequency in this phone that I use here is 800 MHz too. Found out other people were ahving the exact same issue due to poor coding in this topic: http://xdaforums.com/showthread.php?t=2496075 . I'm out after a ROM either 4.4 for stability or if the same lolipop that runs stable, has good reception and low power usage. I think the CPU should be sufficient so I was wondering if this ROM has good coding for reception (RIL) already fixed from install and if it's not that stable that the could kitkat can recommend some other ROMs I can use.

Currently my internet connection is slow so I don't have the luxury to download lots of ROMs to test likethis BlissPop, Euphoria, custom CM 10.1, Omnirom, LiquidSmooth, Vanir and then comes kernel like WerewolfJB and iodak. mourta etc. I think that maybe the final release of OmniRom would have good reception at least based on their changelogs, maybe no need for custom kernel just use omni final? Choices are like too much for such an old model :) Good thing thought so I can keep using the old phone.
[LG Optimus 4X HD] lg-optimus:
I am in a similar situation, I tried a lot of ROMs and Bliss was the best for me, except with GPS, so I have too look for another ROM or someone comfirms, that there is a change with GPS. To test choose GPS with device

only

, so AGPS is NOT used and then test the GPS-signal eg with AndroiTS GPS. If the accuracy is still bad after 20 min there is a problem with the ROM. Last night I got 10-20m accuracy, while with an old SGS+ I got 4m at the same place, before changing the ROM of the SGS+ I had 70m accuracy.
[LG Optimus 4X HD] Ernoz:
If I remember correctly even stock had problems with the GPS from what I remember, i think you should probably try to get another phone for this particular function. People have said that replacing the gps.conf could help significantly on phones like you said others have even gone as far as to conclude the hardware is too weak.

Here is a post about somebody claiming replacing hardware did the trick: http://xdaforums.com/showpost.php?p=61563239&postcount=36a

Of course other variations in code on GPS function and ROM could matter in terms of quality and resource usage but antennas are crucial and they might have saved some money on those on this cheap phone. Other more expensive phones like my fathers old S3 have no problems whatsoever on stock.

During video call via skype other person can't see me just green screen, anyone have same issue ?

He tried but in TWRP,which is recommend recovery,shows an error.
[LG Optimus 4X HD] kelly66:
Hi tool_king, I am also planning to try this ROM (moving from Mokee 4.4.4). I have CWM currently and have taken a backup. I tried installing TWRP 2.8.6.0 through TWRP manager but when I say install it is asking me to confirm whether this location / dev / block / mmcblk0p1 is correct, else I will brick my phone. I went ahead and said Yes but it gave an error saying I have multiple google accounts etc etc.

Any suggestions on how to go about the installation? Also, once I install will CWM coexist or do we need to uninstall CWM first or later? Will I be able to restore from my last backup (taken on CWM) via TWRP?

Pl confirm.

Thanks.
[LG Optimus 4X HD] tool_king:
Concerning the installation:

Just download the latest TWRP image v2.8.7.0 from here ( https://dl.twrp.me/p880/ ), save it to the root of your internal sd card and name it recovery.img.

Then just type the following commands in the Terminal app (in case you haven't install one yet, I recommend this one: https://play.google.com/store/apps/details?id=jackpal.androidterm ):

su

cat /sdcard/recovery.img > /dev/block/mmcblk0p1

Ready!

Concerning your other questions:

You don't have to uninstall CWM before installing TWRP, but be aware, that you can't have both recoveries at the same time. So you will have to go back to CWM, if you want to restore a CWM backup.
[LG Optimus 4X HD] kelly66:
Thanks tool_king. I tried placing the image under /device/sdcard but it says recovery.img not found. When you say root of sdcard did you mean the root folder under device or sdcard folder under device.

After the above is done, if I reboot into recovery will it go to twrp or do I need to do any thing else twrp manager to install it after the "Ready" stage you mentioned above.

Thereafter, how do I uninstall cwm? Is there an uninstall.zip?

Thanks for you quick response as always!
[LG Optimus 4X HD] terirem:
Is there going to be an update soon? :)
[LG Optimus 4X HD] kelly66:
Looks like I missed a couple of spaces in your command. Got it right now. When I went into twrp manager and rebooted into recovery it went to twrp. Even from rom manager if I say reboot into recovery with cwm it is going into twrp (hoping to hear from you on how to get back to cwm, just in case).

In cwm I used to keep the install zips of ROMs under mnt/shell/emulated/download. Not sure how to locate the same in twrp. Any specific location one needs to keep it for flashing through twrp? Any specific wipe sequence for a clean install?

My baseband version is LGP880AT-00-V20b-466-92-MAR-27-2013. I have seen some of the users have moved to 20C. Hope that isn't a precondition to use this ROM.

Ok, went to TWRP manager and added the ROM and Gapps zip and thereafter when I rebooted into recovery I was able to see the 2 files under sdcard/download. I don't think I will need to go back to cwm since twrp appears to be way better (first impression).

Took a backup before flashing the files....however, after wipe (factory reset) and wipe system and dalvik cache as suggested by fritzcola in OP, when I tried to flash BlissROM it did go through in a flash, showed the twrp logo screen and came back to install screen, which means the install DID NOT go through! When I flashed BankGapps next it did show that flash was successful.

I tried the 2 flashes again (ROM did not go through again) and when I rebooted, it was hanging on the LG screen. So, restored the backup. Any idea why the ROM is not flashing? Should I wipe anything else by going into Advanced wipe?

Where am I going wrong? Any suggestions?

Edit: SOS:

Hi tool_king, I once tried the wipe factory reset and this time I did format data as well thinking that I can restore if did not go through again. ROM flash did not go through this time too, but I am not able to restore the backup.

It is saying no partitions selected for restore and Restore Complete : FAILED.

How can I get back my restore - PLS HELP.
[LG Optimus 4X HD] kelly66:
PLS HELP tool_king!

---------- Post added at 11:00 PM ---------- Previous post was at 10:03 PM ----------

Can anyone else help? Have I bricked my phone?

If I say reboot to system it says "No OS installed". If I say wipe again it shows an Error "E:Unable to stat '/data/lost+found'.

What could be the solution? If try rebooting will it stop at LG logo again?

Suggestions please!!!

TWRP faq states that the above No OS installed message means you have wiped your system partition. Unfortunately, I did not take a backup of the twrp backup onto my PC. All my PC backups are on cwm. Anyway, I can sideload the cwm backup?

I should have waited a little longer rather than doing format data in a hurry. I am stuck now!

I had to keep the battery on and use the LG Mobile Support tool and use Upgrade recovery under Options and went to 20B directly.

BTW, JB is much smoother than KK although I am yet to install all apps. I feel I may even get a better SOT. Lets see....

Yep, but i'd recommend you to install TWRP v2.6.3.0, then reboot and download the 2.8.7.0.img. Then reboot to recovery and hit the "install" section. On the bottom right you can see "images" press on it, search for 2.8.7.0 img and clock on it. Then check recovery partition and swipe to confirm. Then go back and click on the reboot section. Then hit reboot to recovery. After it rebooted to the "new" recovery, wipe /system, /data, /cache and /dalvik-cache. Then flash Bliss and your gapps. Then reboot and enjoy it!

When I updated to 3.8, I had heavy lags and apps taking too long to open, but my SIM Cards problems were fixed and the a bug that restarted ui when the device was too hot is fixed too.

Ok guys, come down. For me after doing a clean install, everything works without ANY lag, so please try to perfom a clean install and if the problems still remain please tell me. But be sure in this version i didnt really changed any in kernel apart of using updated toolchain, so it has the be a problem with toolchain or the new Bliss commits. But as i already said i'm working on a new version with a lot new things and of course with some kernel patches. For now perform a clean install and/or switch CPU Gov. Thanks ;)

To all using this fine rom;

fritzcola has gone out of his way to build this for you. fritzcola did this in his precious spare time and for FREE!

If you wish to use this ROM, you are free to do so.

If you have issues, hare are a few things you can do

Post a log with a description of the issue you have. KEEP IT SHORT and sweet, no expletives are required.

Post a screenshot showing the issue.

Ask for help NICELY!

If none of the above can be met, move on to a different rom.

XDA is first and foremost a Development forum. If you want to be here, then help be part of the solution and not one causing the issues.

So now lets move on but with the above in mind:good:

Thank you

CPU Gov: interactive

Gov Settings: boost_factor=0

CPUQuietGovernor: balanced

I've still lags even after clean install. I it seems that there are a lot of different O4X out there and for everyone other kernels/Settings are the best :p and the bad Rom performace is not related to BP 3.8, I had this Problem also with 3.5, since CPUQuietGovernor bring up. Maybe this is causing Trouble? after tweaking around a bit I found the best Settings for BP 3.8 for me, look at my other post if u have Problems to ^^

Don't know where I should post an IMHO very important feature request. It took me years to find out, that there is a problem with the gps fix if

AGPS

is

active

and if there is no

data

connection. This is especially critical when using a navigation app in the border region of a foreign country

without

an expensive data plan. If you are testing gps it looks like it works, but then it fails and then it works again. The problem occurs always then, when you are travelling a lot in border areas and reach the home network sometimes again. It takes very long, that the phone recognizes, that it should not wait for an internet connection and use the last fix without AGPS. There are 10-20 min. without a fix, when AGPS (data connection) is lost.

It works a lot better, when you disable AGPS generally and activate the device only. But then you have to wait at the beginning after the start of a navigation app.

So my feature request is "

Use AGPS only when you do NOT roam in foreign countries

"

This is not a perfect option, since the situation can arise in the home country too, eg in the mountains, but the situation happens not so often, that you are driving in an area with no data connection and you do not come back in an area with a data connection, while in foreign countries it doesn't change, that you don't have a data plan.
