[Q] a few l7 rooting questions

Sorry if this has already been covered before, but ive been looking around a lot and havent had much luck.
I just picked up a lg optimus l7 in china, and found out that theres no way to access the google play store or add a google account. I looked into it and rooting seemed like the way to solve all that. I'm assuming rooting will allow all the normal android capabilities to return.
I'm fairly computer savvy and feel comfortable going through the root tutorials to root my device, however thee was a few things I wasnt sure about.
One, when choosing the firmware, should pick the one my phone is currently using? for example, my device is running V10c, so I should download the China v10c firmware, right? and then follow the rooting tutorial for v10c firmware? and even though it says china unicom underneath, the phone should still function as it normally did after a successful root, because I am using a china mobile sim card with the phone, llike there is no risk of it loosing its calling and messaging functionality?
Also, will the rooting process affect data stored on the sim card at all? I dont think it does...
Thank you very much, Im sorry if this has been answered elsewhere, but I have looked quite a bit. Its also kind of annoying to have to deal with chinese internet, so the less time I have to spend trudging through the great firewall the better.
thanks in advance

As far as I know china don't have play store, you can retrieve the file from the other firmware.
I don't think there will be a problem with the messaging and phone when flashing with other firmware. As an example for this is my phone, my phone is from Canada a P705g and I successfully flash it with a v10i and v10k Europe open. And I'm using it here in the Philippines and I'm using the simple blue rom from snx.
You can follow this thread:

Here the author compiled the instructions in one thread.

thanks for the help,
now im sure this has been answered, but I have been unable to find information on which version of the firmware to select. Does it matter whether you choose v10a, v10c, or v10i? besides the occasional change in rooting process, do they offer anything different?
again, thank you for being very helpful.

actually i really dont know the diff between the versions, most of the devs and users here prefer to use the europe open v10i coz they said its more stable and also the v10k. as you can see on the devs sections they always suggest to use these firmwares because they successfully rooted it. in fact most the custom roms, simpleblue from snx and cyan optimus are based on these two firmwares.
for rooting with v10a, v10c and v10i, you can use petrescu rooting guide here. this is the first guide I used since my phone P705g comes with v10c.
for v10k here.

Alright, so I downloaded the open europe v10c to flash on to my phone after rooting it. Ive followed the guide and had some issues. I rooted the device using the runme.bat program, then I used the lg support tool to try and find the divers, but when I clicked to install the drivers, nothing shows up. So i connected the phone using the install option and it seemed to install the drivers itself. I installed the parser, enabled the enabler and ran the too to flash v10c onto my device. It worked fine and then got stuck at 4%. I was finally able to get it past the 4 % by starting the upgrading while in emergency mode. This works until 99% then the program says it looses communication. It looked like it installed fine, however it will restart constantly when turned on so its unusable.
could this be a problem with the firmware? or is there something else ive done wrong, ive been trying to download another firmware to flash, but i havent been able to get to the download page from the main website, has anyone else had this problem?
im on a l7 p705, does it matter that i tried to flash firmware for a p700 onto it?
thank you very much

My phone is P705G with the original firmware V10c, I was able to root my phone using petrscu's rooting method here: http://forum.xda-developers.com/showthread.php?p=32031942
I was able to flash/upgrade to Europe open V10i which is for [a P700 model. By following the above link where there is [a link how to flash kdz.
Be sure to follow all the instructions. The lg driver, the setting of the phone, the settings of the kdz flasher, etc.
By the way, what os are you using?
I'm using Windows 8.

My Phone is a p705 with v10c
I was able to root fine with the guide, but I'm having trouble flashing another stock firmware. Ive tried europe open v10c and Hong kong v10c as well. Ive followed the guides perfectly, with the exception of the driver installation that i mentioned earlier. When I use the support tool and click to install drivers, a window opens up to select my phone, but no option exists. But I think my phone loaded the appropriate driver. that would be the only situation where I would have gone away from the tutorial, but ive looked around and havent been able to find any information on it.
When I try to flash the firmware, the updater gets stuck at 4%, I've gotten it to work by playing around with things, but nothing is consistent, (ive tried disabling the lg modem, but that doesnt do anything consistantly) then it reaches 99% and im left with a phone that keeps restarting for no reason. Ill try again with the firmware you mentioned and download the europe v10i and see if that does anything.
by the way, thanks for all the help you have given me!

your welcome, chpv. sorry to hear about your problem in flashing, I really don't have any idea whats the problem. Im no expert on this, I just follow all the instructions given here on this forum and so far I didnt experience the same problem as you are. I hope somebody will come and help you.
but for now, can follow this guide here, and use the KDZ_FW_UPD.exe for flashing. install the usb driver first before flashing.
and download the usb driver from here. I assume your using windows.

sorry, I forgot to mention. I'm using windows 7 64bit
Do you know if anyone has been able to flash a different firmware onto a chinese p705? could it just be that the chinese phones are slightly different. I keep trying, reinstalling, going through the steps online, trying other methods ive found as well, and everything just gets me stuck in what i think is called a boot loop. I keep scouring the forums and finding nothing. Ive seen tutorials for harder ways of flashing firmware, but it seems that if all I want to do is flash stock firmware to get the access to the normal google functions, it shouldnt be this difficult. Ive thought about trying the "harder" way, but there are a few steps Im not sure how to do, and there doesnt seem to be a video tutoral
hmmm.

So sorry to hear that, I'm not a developer and just ordinary user so cant really help you much further.
Why dont you try to pm some of the devs here like petroscu and xorox, they are one of the first to root our phones. You can also try normand, or just scan the p700 development thread and pm one those guys that you think can help.

@chpv; if you still haven't successfully root and flashed your phone try this guide here. Its already rooted v10k, w/ unlock bootloader and cwm.

thanks a lot, ill give it a shot, and post results

[Q] flashing recovery and Rom from a new user

So I've rooted devices before, but this is all new to me. Its been a few years so please forgive me.
I have a LG G2 V980 from Verizon. So far I've managed to root with ioroot post 4.4.2 update. I have the Rom I want on my' sdcard' or whatever you want to call the root. For the life of me, I can't figure out how to actually flash it (is that the right term for installing a rom?).
I believe my issue is in the recovery. The guide for the Rom says to use twrp but I don't seem to understand how to install that either. I've used flashify and Rom manager But to no avail. When it does boot into it, or at least I think I am, there is an error message about authenticity then a blank screen.
Does anyone know what's going on here or can point me in the direction I need?
Thank you all for the help.

No download mode no recovery mode

So it all started today when I tried to flash Cloudy G3, it didn't work, it soft bricked I restored backup, all good. After this, my phone started acting weird by powering up again after I powered it off, not opening Quick Remote and saying SIM is not ready. So I decided to give Clopudy G3 a try once more but I needed TWRP, I installed the TWRP i needed but I got error status 7 so I used flashify which was recommended to me. Well I flashed TWRP using flashify and, now when I try to get into recovery mode it enters fastboot mode and stays there. I figure the solution to this is going back to stock, and I found that the best method is from a dude called Hyleton in XDA But that falishify thing left me without a download mode! No recovery, no download... is there even a fix for this?. Now my phone is the international version (D802) but this guy has trillions of firmaware for lots of different D802s and I don't know which one to download and use! I downloaded the one in the folder that says "D802 tot" and selected the 32GB one. Can somebode PLEASE, FOR THE LOVE OF GOD HELP ME, my knowledge on rooting is pretty basic, and a lot of the things in that thread, like for example the word "TOT" I don't understand! http://forum.xda-developers.com/showthread.php?t=2432476&highlight=d802
Now can somebody please explain this guide to me? I am wanting to do the second method (the TOT method). I would really appreciate this, REALLY REALLY APPRECIATE IT.

well
I wont be much help, but maybe i can simplify for people who come accross this thread. Ive read it a few times and im quite confused.
You said you flashed cloudyG3, had problems, then went back to stock.
What recovery did you use to backup, restore, and flash cloudy g3?

No i want to flash stock, after trying to flash Cloudy G3 I used flashify to flash TWRP and it went nuts and and now my phone is working strangely. I'm currently trying to go back to stock in the hope that it'll fix my problems and I'm using Hyleton's guide, as I have no download mode I'm gonna use a .kdz file but in his guide there's lots of KDZ files and I don't know which one to use! Any idea on that? http://forum.xda-developers.com/showthread.php?t=2432476 here's the thread and if you look at the stock firmware files you'll see there's tonnes of .kdz for the D802, could you help me find the correct one for my phone? My phone is simply D802, no other letters like the ones in that list have (which confuses me as to which file I have to use to flash stock) and I bought in the US, but I live in Argentina....

LG G2 wont boot after installing autorec

first i wanna say that this is my first time trying this and after a lot of research i thought i knew what i was getting into but now i feel completely lost. earlier today I rooted my phone using one click root then installed twrp using auto rec. auto rec seemed to work fine and i clicked open in recovery just to see if it worked. twrp opened no problem but when i went to boot the system back up i started getting security error messages under the LG logo. i tried getting it to boot again after formatting and now its just stuck on the LG logo and not doing anything at all. im almost positive i have a d800 version and pretty sure that i used the right autorec file. i was running 5.0.2 instead of kit kat so not sure if that had something to do with it. please help me out anyway you can, i really need to get my phone working again for work and not sure what to do. i tried searching for an answer but had trouble figuring out what to do.

Yes definetely it has something to do with it. Because autorec uses kitkat kernel. You just have to flash lollipop kernel and you're good to go.

Flash stock firmware with KDZ (Lg Flash Tool) there are a lot of tutorials here on xda.
Good luck.

I'm in the middle of the TOT method right now to get it back to stock firmware, seems to be working. so now if i want to start over and root/get twrp on my phone any suggestions on the best method? i've read a lot of different ways to do it and not quite sure what would be best. sorry if this seems like an easy find, i just dont want to run into this mess again ha.

Lg g2 wont turn on after installing autorec
I have tried to install auto rec on my g2(4.4.2). And now the wont boot and not even going to download mode. When i connected the phone to the computer phone is not getting detected. In the device manager it is shown as android phone=> android bootloader interface. when i try to turnon the phone, the screen just displays some vertical and horizontal lines on left side of the screen. Please help !!!

Stuck on boot

Hi
When I wipe devik, data, cache and system partition using TWRP and reboot, the phone take forever to boot it stuck in LG logo. I don't understand why it stuck when I wipe those partitions. I've tried combination keys to boot in TWRP recovery but it doesn't work. Now I'm stuck. I don't know what to do. My phone is LG G3 (F460L) Android 4.4.2. Please see the photo.

EDIT: I didn't read the system partition thing before answering below... If I'm not completely wrong, your phone can't boot, because there is no system which could be loaded, so your phone is more or less empty, when you wiped the system partition. No more Android 4.4.2 :/ I don't know, why booting into TWRP doesn't work. Maybe you carefully could try to unbrick your phone and reinstall stock rom again.
Hej,
have you ever had booting problems with your phone? I'm in constant bootloop trouble with my D855. Some say it's a battery issue, which I can not confirm since I've tried 4 different ones (including 2 brand new ones). Some others say my mainboard has kind of an unrepairable defect. As I go with this possible explanation, I ordered a new used mainboard from China, hoping for it to arrive in Europe and not beeing fished by the authorities...
I can't say for sure what is the exact issue with my or your phone, the only thing I can tell is that there are tons of posts that can be found on the internet about the G3 having bootloop issues after a couple of years of normal usage. And for most users this came all of a sudden. Believe me, I've invested days of research, uncounted attempts of unbricking my phone (I thought I bricked it somehow, but it wasn't the case) and flashed stock rom and LOS as hard as I could. All ended up in my phone not running stable, crashing and then bootlooping. Sometimes (most of the times) if it's shut down and I want to turn it on, it gets stuck on the LG boot splash screen. It seems that somehow the energy management is not capable of running the phone stable under low voltage, since at least for me the probability of successfull boots slightly rises with a higher state of charge. But I can't take it for granted...
Good luck for you, I will keep reading this thread.

I wipe System Partition which contains Kitkat 4.4.2 but I already flash new ROM (CM13 Unofficial f460) after. There should be CM13 in system partition. I don't know why it can't boot. On the other hand, I can't find official firmware 4.4.2 for F460L (3hours search still no luck). I found only official firmware 6 Marshmallow which I'm afraid I won't be able to root forever if I flash it. I'm really appreciated if you can find one somewhere.

You could follow the link in this post which leads to a russian site. I saw a 4.4.2 version of Android in there. Good luck!

Thanks. I found official firmware lollipop and flash it. I've been searching for a way to root it but most of the method is for D855. Do you know if F460L Lollipop is rootable?

You can use the search function within the forums or search engines like startpage. I don't actually own a F460L and I'm not an expert either, so I don't know, how it works exactly. Punchin the keywords "F460L Lollipop root" into startpage.com brought me the following link as first result:

Just follow the guide in OPs post

I already try LG One Click Root. It doesn't work. When it reach 45% (Looking for LG Serial Port), the phone restart (normal reboot) and it stay at 45% definitely. I manually reboot to Download Mode, still, 45%. Any suggestion?

Sorry, as I'm on a D855, I don't really know. I rooted via King Root which only works with a specific Android version. I used this guide which helped me a lot: https://www.youtube.com/watch?v=8VOgM3jLas4
It's for the D855 but it could work with the F460 too. In the video description, there is a download link to the specific stock rom version for F400 models. The guide tells you where and what to download and how to install. You could try this and I'll keep reading Good Luck!
