So,i have a few question for you guys if you wanna help me.I search,and i flash the firmware and after i root the phone.But after a restart,when it boot on the screen was appear "Security error" and phone turn off.So,my first question is:I can`t root the stock rom?
Thanks very much guys!
Hi.
No there is already 10i, but we don't know changelog's from LG, so probably nothing significant.
What method have you used? Root this phone it's very easy and you can find a couple of methods in development area.

10i version mentioned here: http://forum.xda-developers.com/showthread.php?t=2602193.
I don't know if KDZ is available but you can search in XDA or google. Maybe it's better to stay with 10H.
For update I've used several times KDZ_FW_UPD with no issue (follow this: http://forum.xda-developers.com/showpost.php?p=44874388&postcount=36)
I've used the zv9-ZVB-Universal-Root (attached), because it was necessary to changed the bat file, unlock bootloader is afterwards with FreeGee.
What is the version of your phone? Are using the right kdz?

I find the 10I kdz but not for my country.For a few others,maybe i will recive later.Yes,i think now i stay with 10H version.
To clarify me,for work root,it`s necesary to have unlocked bootloader?Or unlocked bootloader it`s my option after i rooted it.
With the files you give me for root i must follow the same procedure?Run CurrentRoot with phone in Only charge mode,after that change to MTP and Enter?
Thanks for the file and topics,are really useful and what exactly what i want and i don`t found.
EDITn lg firmwares official site on my country i have the V10H version.But now i download the lg official firmware,enter the IMEI and the app give me V10F version.And now i check the lg site again and V10F version are last for service provider where i bought the phone and V10H are without service provider name(EX:V10F for Orange/Romania and V10H for Romania).Can be this a problem?
No. Root is independent from bootloader, but to unlock bootloader with need to have root.
Yes, that is the procedure to run .bat file. .
I'm not sure about your country, is your phone from Orange/Romania? I think that you can install 10H, but not sure wait for other user confirmation or install 10F to test...

I understand.Maybe first i did something wrong and that give that security error.I wil try again.
Yes,it`s from Orange/Romania,was a network lock phone but i decoded it with IMEI.I have the V10H and runs well,a just ask about the V10F version cause the Lg official firmware app show me that version to be the last and i think can be a problem with compatibility and that give me Security Error.Thanks very much for answers and for your patience
I´m new too.
I flash the rom again,and root it,restart a few times and works.But,after i unistall with Titanium Backup some apps who don`t use(google movie,books,music,lg note,email,smartshare,cell broadcast,google+,youtube,chrome) and restart,again appear the error with Security Error and phone don`t turn on.I don`t know,are something to do with root or are some apps that must don`t be unistall.But i didn`t unistall any other system aplications.What did you think,sir?
For sure it's an application issue, my advice is to google about system app that can be uninstalled.
You can also uninstall one by one to identify the ones that gives you security error.
Don't forget to do a backup first!

You can return back to stock with this usefull guide http://forum.xda-developers.com/showthread.php?t=2388440 (it works very well especially if you have a kdz>1GB ) or simply with KDZ updater( you find guide there http://forum.xda-developers.com/showthread.php?t=2010624 ).
I coundn't find the way to change the stock video player (which is quite buggy, slow and no option for full screen) in web browsers in CM11. It would be gread if we could choose for example MX player instead. Is there any solution to this? Thanks.

It works on my E975 with German Stock V20A
use towel root. it roots your phone in a fraction of second.
Root finally achieved on CAT B15Q.
I tried all the simple methods, none worked.
I used PDAnet USB drivers.
To achieve root, I made a recovery using the CWM method with SP Flash Tool V5.1408.00 following this guide
chinaphonearena.com/forum/Thread-Tutorial-Ultimate-no-root-backup-CWM-MT6582-MT6592-MT6589-MT6589T-MT6577-MT6595
Recovery was patched using MTK Droid tools. However, SP Flash Tool V5 would not flash the phone with the patched Recovery and Boot files, so for that I used SP Flash Tool V3.1332.0sn187. Then root using MTK Droid tools - Superuser (SuperSU failed). Also useful was this guide
chinaphonearena.com/forum/Thread-Tutorial-How-to-build-CWM-and-root-Bedove-X21-MTK6577-and-other-MTK-phones
Note: When plugging phone in for flashing (this is done with the phone OFF), put battery in, plug cable into phone, hold volume down button when you plug the USB cable into the computer.
Checking with a root checker, it told me I did not have full root access, even though Superuser appeared to be working, I only had temporary root.
I then used Root Genius, which finally achieved full root.
A bit of messing around, but worth it.
Install busybox.

Could you make a tutorial?
Yes, a detailed tutorial how to successful rooting a Cat B15Q would be greatly appreciated.
I've tried with towelroot, but app says phone is not compatible.
Newest chinese version from RootGenius is 1.9.6, but international version is only 1.8.7 from
march 2014. Has anybody tried successfully with one of the versions?

any more informations?
did i understand correctly, root genius works?
just want to be sure before i try it, thanks in advance
Roor genius didn't work for me. Left my phone in wierd state (screen flickering during call). Had to do factory reset after my root tries.
i hope this thread wont die, there isnt much information on the web on how to root the b15q.
has anyone found some good links, or some in any way useful info that they could post here?
i really hope this will turn out better than with the b15, where after half a year there was still nothing reliable
thanks in advance :good: :fingers-crossed:

Can you tell us which version of RootGenius you used? Chinese 1.9.6, or older international version 1.8.7 from march 2014 ? Or another else?
For info: I have tried to contact as672 for more details, but no answer until today.

It's an apk fille (in chinese). Just download, run, wait, reboot and voila... Root is there. At least i have it on my B15Q since morning. Root is persistent (still rooted after multiple reboots) and controlled by KingUser app that you will get preinstalled after running thar chinese apk. How much is it safe or not I have absolutely no clue nor guarantee. For me it works without any problems (so far).

Dear cityshark_cz,
thank you for pioneering to root @ my CAT B15Q, keeps any reboot, all works fine!
Through rooting installed Kinguser App is near equal to SuperSU or Superuser.
Hopefully without Chinese back door...

Hey guys massive noob here, wondering if it is possible to downgrade from android l to kitkat or to root android L on the G3. I foolishly updated and my root is gone, stump is not working (obviously not made for L yet) and I can't find any help elsewhere.
I need to root my phone and I don't care whether the the best way is to downgrade or to root if it is available for the new os. I will lose my data other than what is backed up via dropbox etc but it's not a big deal for me.
Help much appreciated thanks
Yes it is possible just downgrade to Kitkat using the lg flash tool then root using Purpledrake

I've fallen at the first hurdle, which firmware do I need?
I have a UK vodafone LG G3, 16GB, LG-D855, and I want the last version of kit kat available. I'm more than a noob.. .
Also why do you choose Purpledrake over stump, is there any difference?
Thank you so much
This firmware you want is A6VF, it is near the bottom of the list.
The reason I use purpledrake over stump is because some times it won't root and says "...Not supported" but feel free to try stump if you want and if it doesn't work just use purpledrake.
Hi. I got trapped with unrooting and updating to lollipop lg g3 D85520e-EUR-XX and wanted to return to kit kat 4.4.2. It's the 32 Gb model. Can you help with the KDZ i must download (I can't understand the four first characters of the list!). Thanks!
What network are you currently using? or is it an unlocked phone. A country name would also be helpful as that's how the files are organized.

It's unlocked. It's in Spain. Lg g3 D85520e. 32 Gb model. It came with kit kat 4.4.2 and i aplied PurpleDrake succesfully. Then I unrooted to upgrade to Lollipop 5. Ver. 20e. And now, I can't root anymore. So I would like to downgrade to Kit Kat 4.4.2 to be able to root again with PurpleDrake to recover my root privileges, especially to manage apps and their writing to the external sd card.
Thanks very much for your help!
To get the exact suffix required use this website
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=IMEI
Replace IMEI with your imei then press enter. Then post your suffix
It looks like if it were the same KDZ already installed... : FW9BRPVE022NAX045560S86/D85520E_00.kdz ??? What I need is the Kit Kat version 4.4.2 10x(a,b,c,...) to downgrade from this one (20e) and be able to root again the phone. I probably have explained myself wrong. Any idea?
