Bootloop LG G Flex 2. - LG G Flex 2

The problem is that I have edited the file build.prop. When I restarted the phone, there was a bootloop and will not let me enter download mode. That I can do?
Thanks...

Please can you tell us what model your phone is and also the firmware version if you know it.

H955, firmware version 15c

If you have system.img or rootedsystem.img on your internal sd use dd commands you can find on a couple of threads around here (sorry, I'm not being mean, I genuinely don't know where to find them as I've never used them to restore).
If you don't have the .img file I suggest using LGup, you can find the download link and a guide here.
And you can get a KDZ that's even more up to date than what you had here.
I really hope this helps you as I've been in exactly the same position as you after a build.prop edit and I sent my phone off for repair before I found out about this.
It took 3 weeks to get it back (it was over the festive season) and it was the longest 3 weeks of my life.

Download a kdz for your phone, then reflash it, in normal mode so you dont miss your settings

Ok... I am going to try it now

Finally, I managed to get the phone to work with KDZ...
Thank you all!

[Q] lg escape boolsheet

yo xda,
so, i'm a nooblet but i have been lurking the forums here for support on all the androids i have ever had.
what I'm posting I would like to post in this thread...
http://forum.xda-developers.com/showthread.php?t=1976116
... but since i am a noob, i cannot.
so this is a problem with the lg escape. i just should have never got an lg in the first place
i did the latest root option that was posted on that the thread, i believe on page 13 for v10f
it was all working super bueno until i tried removing some of the stock bloat apps with titanium backup. and yes i backed everything up on my computer beforehand
after uninstalling those stupid apps, i tried restarting the phone but got a security error message at the boot screen. phone wont start
i looked at some other threads and saw that some lg nitro users were getting the same problems when removing certain bloat apps.
i tried the factory reset, which is really weird for the lg escape btw, but after the android figure with the loading bar pops up, it goes right back to the same security message.
Can anyone help me?? or is it just another brick... i bricked an lg thrill only 4 months ago... hahaha. stupid lgs
i just sent lg support an email too.
Try to flash with the kdz file again
This phone don't have recovery yet. All he can do is restore the original firm with the kdz file. You should try the last firmware v10i, now can have root

I've tried flashing the kdz. But I have never done that before so I'm not totally sure I'm doing it properly. I downloaded the LG kdz flasher tool and the kdz file but how am I suppose to get the flash tool to recognize the phone if I can't get the phone to turn on?
Thanks for the help btw guys
Yes, connect the
phone while holding the
buttons pressed volume
up and down at the
same time. The phone will turn on in download mode, and then you can flash the firm

Help with US firmware H950? Bricked Flex 2

So pretty new to this form I'm from the United States I have a LG flex 2 h950 I rooted the other day and then I installed a application that fixed permissions... once the permissions were fixed the phone turned off and just started boot looping afterwards. I couldn't find software for my phone so I tried flashing H955 software...bad idea... the phone works but seems only the cellular service doesn't work...if there's a way for me to enable the radio somehow or flash different radio please let me know because it's really frustrating I know I'm dumb that i did it to begin with but i can at least use the phone besides cellular service .I didn't know if somebody has a spare H 950 software in there pocket or if there's another way to go around it I can't get anything from LG and I can't get anything from AT&T so pretty much I have a phone that I can't call with or text with also I noticed whenever I go to the hidden menu and I go to phone info...it says this application does not work with this device any help would be appreciated.
On my 3rd flex 2 at&t. I called and made something up and they sent a replacement. They never check. They just refurbish the device as long as it has no external damage.

Really? I was thinking that. But its not my plan. Its my girlfriends i didnt wanna get her disconnected. Because it is also rooted. I heard they can do that. I didnt kno if i could modify something in build prop or flash something. It also sucks because i like this phone and there's no recovery which got me in the situation to begin with. Thanks for the advice though. Im still debating if i should do that or if anyone has any other ideas? Thanks
did you modify the system folder? i can help you with that
- didnt' read your story.
I don't know if i can help you
there are no stock images. but if there is pieces from the rom you need. I can send them to you
The system folder? What would i have to modify? I had a couple ideas but they didnt really work lol...long story short cant find att stock firmware h950...rooted...bricked...flashed h955 firmware hoping that would work but now i cant get cell service. Says radio is disabled but i cannot find a way to enable

ahh bricked LG's. they are really hard to restore.. i remember when i bricked my lg g pro f240k and it took me forever to restore but eventually i did.
it was soo easy.. much easier than i thought.
okay, try this buddy
http://lg-support-tool.en.lo4d.com/ << download and install this. as well as lg drivers.
put your phone into download mode.. and then leave it there.
connect your phone to your pc, and then click find software or something like that.
after youve done that...
it will find the appropriate software and flash it automatically, although you will lose your root, and you might end in android 5.1.1
however i am not too sure...
btw leave a thanks and tell me how you got on!
Cool thanks much appreciated...i will let you kno tomorrow. While we are on the subject dose anyone know a custom recovery method for the flex 2 H950? or mabey a recovery from a differnent model that MAY work? So this dose not happen again. :good: many thanks.
i wouldn't mind buddy. give a few hours.
Please keep us posted, cuz I also bricked my H950. I manage to get SU but for some reason I could not install Titanium, so I proceed to root it again via traditional way. Not the phone just stuck at&t logo. Any help is appreciated!! Why can't we get TOT for this phone??

Guys you haveto read b4 flashing.....lg flashtools are outdated...i think thats why they didnt give us the zv9 tot file...

Thats incorrect.. Its not flashtools.. Its the actual firmware file which has nothing to do with the flashtool program.
Anyway Will the ZV8 TOT file be good? or does it need to be ZV9? I think I can get ZV8 but it will cost me $20

Custom Stock Rom>?

@Sj12345 @randrew87 @justinswidebody
Buddys have you seen this LG G4 stock modded rom?
They flash it like we flash our rooted stock imgs.

Its very interesting, maybe we could do the same with flex2?
I made an aosp image if you want to try.
Compiled and everything appears great. I will try it but now I have not time to do, If it works, I will make the tread.
By the way is based on H950.

I dont know If all system and libraries for all version of flex 2 are the same.

Cool!!!! That would be awesome! as long as we have the original system.img in root directory I can assume we could flash back to stock.
I would love to try it out but I'm using LS996. I really dont want to brick it tho.
PM me a link I may attempt to try it out. :good:

Well, I cannot do with download mode, I have to reflash kdz with flash tool but all right, phone is back.
I dont know what means thats error, but is fixable with kdz...
At least the versions that have one....
Maybe my rom is wrong and is not related to bootloader.
I mount both partitions, stock rooted and my aosp compile and move all data of my compilation inside stock image, with -a parameter from linux, so preserve all data, links, properties and permission, but... Error 9

post 67 tells that the problem is kernel modules and modem.
what I do to test is: step by step:
take the img of stock image and the aosp compiled one
mount both in diferent folders as we do to make a rooted image
then, take all files, folders and symlinks keeping all properties and paste over the stock image, so If any file is missing, in my "modded system.img" will be there.
then flash the modded file as the rooted system in the phone from download mode, with send_command.
I have everything, If you want to check the image, I can upload it and you can test it.
there are 2 problems:
1- Its made with h950 files, so I think its not compatible with the other versions.
2 - for people that upgrade to 5.1.1 at&t software arent kdz files aviable, so, if error happens, no way back, so it can only be tested with phones with kdz aviable.
I dont know wich version of phone you have, but If I send you the scrypt to collect files, can you send it and I make the img for you to try
I have the H955 UK/EUR version I'd be happy to try help if I can. I Wonder if its a DRM problem? I used to have Sony Z1 and before all the updates unlocking bootloader lost the DRM keys causing the camera to stop working along with other bits, but loosing the camera was the main problem. Could it be a DRM problem?
perhaps one of the devs from the lg4 forum could help you to fix it?

H950 dump

Hi, I need the dump to try to fix my phone. I need an h950, but If you have another version, we can try, and we can make a database to fix our dead phones...
Is an H950, It can be done from adb or from a terminal, root is needed, it only copies first 512mb not all data, If I cannot fix with that, a full one maybe its needed, but I dont think so. If it was a full bakup for privacy, make a wipe or factory reset first
Code:
dd if=/dev/block/mmcblk0 of=/sdcard/H950dump.img bs=8192 count=65535
thanks so much
If you have 11x and up ie Android 5.1.1 previously you wouldn't want dump of any other variant.. It wouldnt help anyway as a qfuse is blown..
Plus i can't help as my internet wouldnt in death of universe upload the dump.
I hope you can fix yours soon

U may try extracting dumps from att 11z tot somewhere around this thread..
I have flashed it when bricked but in the latest scene..my phone overheated and shutdown.. And would not bootup..but download kode was availabe so i restored using the tot..
Everything was fine until i noticed DRM was not working properly.. So i checked my device ids and baaam imei was zeroed out.. Have no efs backups but cellular is working.. Only Drm isnt working..
Is there a solution using nvtools or qpst? Cuz bootloader locked ..

I'd repaired mine, with zero and with null.
null needs much more effort, but with qpst.
Can you make me a dump? I will search If I have a backup of my efs, I dont think so, but If I have a working phone, I can figure how to do it, I fix it two times in that condition with no problem at all

the tot is useless cause I need the partition table in a single img file, and the download mode working in that dump...

no sr, thats system partition only, couriously, system partition, and data arent necesary to boot in download mode.
What I really need is the first mb, I think with 128, or maybe a little more is enough, from 0 to laf partition so I can get download mode, or, at least, try to make it works and reflash

I need that:
You need to be in a rooted phone, and needs a terminal emulator like this: https://play.google.com/store/apps/details?id=jackpal.androidterm&hl=es
anyone can do it
after that open terminal and write
su (to grant super user acces)
then
dd if=/dev/block/mmcblk0 of=/sdcard/H950dump.img bs=8192 count=65535
when it finished, I need the h950dump.img that you created, It will be in /sdcard/h950dump.img
you can zip it, or upload as is anywere so I can try a fix for my dead phone.
