[Q] [Urgent Help] Cannot install rom other than Bell V20 in LG LU6200

Hi all experts
i dont know what happened to my phone that i cannot install other roms apart from Bell V20 rom ported from SU640. every time i install a rom it just boot loops main screen then LG Optimus LTE then restarts and loop continues.
let me explain what i did to my phone.
i was using Sphinx v4.1 without any problem then i saw Pisces FlexUI V5 and thought to install it. but before installing it i downloaed MiUi V5 and installed it but did not liked it so decided to install Pisces FlexUI.
Now the problem started althouh pisces rom installed correctly but it started to give SystemUI crashed error right from the start. My Imei also become blank althogh i took backup of it by using LG Backup IMEI 1.3. i tried to restore it but it didnot worked.
i reinstalled MiUI and it also displayed blank imei. then i downloaded 5irom from this link http://forum.xda-developers.com/showthread.php?t=1672014 and replaed it 10.img and 11.img with mine and tried to restore it but again not successful. i restarted the phone and it started to boot looping same as mentioned above. no matter what rom i tried nothing boot up only Bell V20 was successful and also my imei is restored too.
plz help me i am really confused and worried that why any other rom is not working in my phone... if any one can provide clean backup of installed Sphinx rom from their phone i would really appreciate it coz i think i might give it a try too to restore backup using CWM. i badly want Jelly Bean in my fone. should i try to flash KDZ file will it be successful? i just wanted to be careful becuase i dont want to loose CWM recovery becuase it is the only thing which is doing the work.

Try using philztouch to install ROMs. I had troubles for some reason until I used that. Maybe something's not deleting properly ? In using p930 with CM11 04/28 nightly

no its just an ICS rom nothing special but the thing is it is only rom which can be installed in my phone i am unable to install anyother rom in my phone it just boot loop if i install them. that is the reason iam worried and i want to move to jelly bean.
if possible can u provide me a clean CWM backup of Sphinx V4.1 from ur phone i can try that too may be using restore method will work.

thnx brother looking forward for ur reply. if u can send Flex UI backup too if you can i will try that too. this ICS rom is unable to connect to 3G networks as well.
should i try KDZ flashing? what if it started boot looping after finishing? what would be my other options as i surely would have loose recovery.

u should proceed with kdz flashing, its must after that root it and install any rom u like that will b a better procedure to start all things clean. and uploading recovery will depend on net speed as iv a slow net despite it being a 3g and no dsl or other net available.

Yeah flash a kdz for clean restart.

Dont make assumptions. kdz flashing is not similar to a zip flashing. If you do it right then your problems can be solved. If kdz flashing fails due to some reason then there is a chance that you hard brick your device. So, make sure you are doing it right.

i had experience this boot loop it was stuck on cmw recovery one time( didnot resolve with anything except kdz flashing) and second time with lg lte boot screen. both times it resolved with clean kdz flashing

Thank you all of you for helping i flashed my fone with ICS KDZ and all things become alright and now i am enjoying Flex UI. the problem was that the partitions becomes corrupted and KDZ flashing restored the partitions to their original state and Viola.
thnx again for suggesting me.

Bootloop

Hi there, I have a Galaxy Fame currently in a BootLoop.
I know exactly what caused this, it was me enabling the setting for Andriod Device Manager in the Google Settings.
Rooted, Stock ROM, Stock Recovery.
Please Assist

I have the same problem with both stock and root. Running android 4.1.2. A factory reset via recovery fixed the issue for me in stock.... I have no other ideas as to what is causing this weird and annoying bug...

just,don't enable it ,,do like @itechy

I think it's caused by android device manager... But I'm not 100% sure....

This
Confirmed on two occasions with this phone: the second you enable Android Device Manager it enters a bootloop. Directly after a factory reset too.

I have same problem in my Samsung galaxy fame custom stock rom
solution-format through recovery or flash it again

I know this is an old discussion, but I'm setting up a Samsung Galsxy Chat B5330 for my mother, and after several tries I can confirm that the Android Device Manager in Device administrator MUST BE KEPT TURNED OFF because it causes BOOT LOOP in Android 4.1.2 !!!!!!!!!!

I have the same problem! If I enable Android Device Manager Lock and Erase I get a boot loop! I don't have custom ROM. Problem happened before I got root, and was still here after I got root.
EDIT: I have Android 4.1.2, it looks like other people also posted about boot loop in 4.1.2 with A.D. Manager.

hey i have this issue on att g3 installed twrp through auto rec now boots to security error screen. how can i fix this?

Since you have twrp just flash a kernel or a new rom through twrp.

Cool thanks man. I was kinda stuck there. I couldn't get my pc to see the phone, had to wait for a micro sd card to put the kernel on. Thanks a lot

LG G3 LS990 - ZVB - Rooted + TWRP - Flash Stock Recovery Only
Hi, I am looking for flashing stock recovery on my LG G3 Sprint LS990. I believe the same method will work. I am currently running on stock ZVB ROM rooted and TWRP installed as recovery. In the download folder for LS990-ZVB http://downloads.codefi.re/autoprime/LG/LG_G3/LS990/stock_partitions/ZVB, there is no recovery image file, but in ZVA folder there is. I am just wondering if I can flash ZVA folder's recovery image using Flashify to my ZVB ROM LS990 and if that will work.
My LS990 is rooted and currently have TWRP. i get secure boot error when the phone reboots after accepting Android updates installation that come automatically. I believe installing stock recovery will resolve this issue and allow to install Android updates I do not want to going back to stock completely, that will unroot my phone and again I have do all these staffs.
Anyone can help to advise, will be appreciated. Thanks.

Worked for me
It's not english, it is portuguese Brazil, but it works.

Soft Bricked D855

Okay, so a few days ago I had a completely stock LG G3 D855 v30n Marshmallow. Then I decided I wanted to root it and flash fulmics. So I flashed the v30b kdz with lg flash tool and rooted the phone with rootking. Everything worked perfectly until I flashed the ROM. I made a nandroid backup with TWRP and I downloaded the fulmics 6.6 zip of the xda forum and put it onto my external sd card. I tried to flaash it onto my phone but it wouldn't work (it kept reloading into recovery mode every time I tried to flash it). I thought the problem was I was using an old version of TWRP. So I flashed my backup and soft bricked my device. I have access to download mode. Could someone please help me in unbricking my phone and is it even possible to flash a rom in my situation? Thank you very much in advance.

Ok so,
Connect your phone to your PC.
Go here TWRP and select the "official".Download the latest one,move it to your phone's SD Card.Flash it with TWRP.
And after that,Full wipe and reflash Fulmics.

Bootloop with no recovery installed

Hi guys, it's me again, I have ancountered a huuuge problem on my oppo find 7.
I installed twrp on my rooted phone, than I merged partition with this tool https://forum.xda-developers.com/showpost.php?p=55187001&postcount=558 , than I flashed OmniROM 7 (android 7.1.1) and gapps (yes, I forgot to root again). After rebooting I found out that there was no LVM so I decided to reboot to recovery to retry getting LVM and then root permission but I discovered I had no recovery mode installed and there I made a huge mistake, i rebooted the phone and I found "reset" in settings and I did the reset hoping to restore my old OS but immediately i realized the mistake I did. Now that's my problem: the phone keeps rebooting and has no recovery mode, if I connect it (while switched off) to the PC it turns on and keeps rebooting and I have no way (I think) to enter recovery for the cellphone. What do I have to do to reinstall recovery? Is there any way to restore my poor device? Thank a lot for helping me ( I know I'm a noob, sorry guys )

Try this
Hey frank look up the oppo recovery program itt should restore your phone back to factory settings try oppoforums or google it oppo recovery tool

Yes! I fixed it by flashing TWRP via ADB then installing the new ROM.
