[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.
sent from P705G, flash w/ P700 v10k open eu. waiting for cm9/cm10

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] Android Noob - problems with OTA update

Hi all. In advance, please don't flame me. I am new to Android, and don't understand all of the technical jargon. I have a problem that I hope will be a simple fix - if there is an answer already on the forums perhaps someone can point me in the right direction.
I was given a Samsung S4 by a friend that works for Samsung. Apparently it was some kind of demo model or something - typically given out for promotional purposes (which may or may not be relevant). The phone is factory unlocked. It is running on the AT&T version of the firmware. Here is the "About Device" info:
Model #: Samsung-SGH-I337
Android version: 4.2.2
Baseband ver: I337UCUAMDB
Kernal ver: 3.4.0-440216
My problem: I cannot update firmware. I tried OTA and via Samsung Kies. When I try OTA, it searches for an update (and finds one available), but then says that the update was interrupted and I there is no update available - try again in 24 hours (GRRR!). When I try to update via Kies, it finds the update and goes through a lengthy download process. Once it begins to install it (my screen goes black and green characters flash on the screen - so apparently it is trying to install the new firmware) - it hangs. Eventually I get a message stating that the update failed (or something along those lines) and I need to do emergency recovery. When I start emergency recovery it just hangs....eventually I just restart the phone and it is right back to normal.
I have tried this process 6 or 7 times-no luck. I really want the recent update, which allows moving apps to SD. Again - I am new to Android-everything. I understand that I likely need to manually install a ROM package - if someone could point me toward some step by step directions I would REALLY appreciate it. Thanks in advance for your help!

To try to update more often, try moving the time and date of the phone ahead and try again. If you want to flash ROMS, don't update, because there is no bootloader unlock for it yet

Thx for the reply...and for the tip about adjusting the date/time. :good: I am fine with the stock AT&T ROM - but for whatever reason, my phone simply will not update. I tried resetting it - still no dice. If anyone could help me to reinstall the stock or newer AT&T rom manually, I think that would be ideal. Any ideas?

I don't know much about this, but maybe you could flash the stock AT&T firmware again via ODIN. It's basically "unooting" the device, even though your device isn't rooted. it'll wipe all your data and reinstall everything again. I did this often on my S3 but I'm not sure if it's the same for the S4. Maybe someone else would know better because I don't know the .tar files needed for unrooting the S4.

I'm not flaming you, I am giving you advice that will help you. Try to use the search function to find answers before posting a question that has already been posted several times. It is possible, the help you need has already been posted in those other threads several times. Also, did you see "similar" threads appear while you were posting your question? Take the time to read those first. It couldn't be easier because they are listed for you. You should also read the "pinned" threads in the "general" section. There is a lot of information there that will help you understand things, if you take the time to read it. If you don't understand the "technical jargon" take some time to learn about it before you do anything to your phone or you are guaranteed to mess it up. If you really don't want future flaming, follow the XDA rules and search for answers first. Good luck.

[Q] Please help a n00b...

I was trying to install Cyanogenmod on my razr m running rooted and unlocked 4.4.2 and used flashify to build a flash que of cm stable build dated 7/8/14 and Gapps. Decided against using flashify and booted into recovery without clearing the que in flashify first (assumed it wouldnt actually do anything until i pressed a button... but apparently it actually built a que that twrp used when it booted and this resulted in bootloop. I managed to get into recovery and did a full wipe/reset. then installed same rom and apps again. Bootloop. I've tried using adb to push the cm 8/23/14 nightly build but it doesnt seem to be working. also tried flashing stock 4.4.2 boot.img out of curiosity but got an error "no boot partition found" is there anything i can do to fix this? or am i stuck buying a new phone with a good year left on my existing contract?

Just grab the stock 4.4.2 firmware from here and then grab rsd lite (google it) and use it to flash stock... Let us know if you have any errors and we'll address them...
We cannot teach people anything; we can only help them discover it within themselves.

Thanks for the stock rom, but when i tried this method rsd lite didn't recognize my device.

What do you mean it didn't recognize the device? Like is the start button grayed out as if its not plugged in or like all the status's say n/a? Do you need further assistance with it or is you phone up n running? We are more then willing to help...

I actually have gotten it working again but my parents wound up using the insurance policy for it anyway so it looks like i'll be rooting again soon lol. Thanks for the help

Okay I got the replacement phone and have it rooted. Over this weekend I plan on unlocking the bootloader and having another go at CM

[Q] Help! Flashing rom."system software not authorized by Verizon"

Ok, please I hope you can help. New to rooting, I rooted my s5, and was working fine for days, then I got the error and yellow triangle "system software not authorized by Verizon" I downloaded one md5 firmware I found and flashed it using odin, after was done had the same error though. I was on version 4.4.2. (don't know if that matters) I cannot find any other "stock" firmware online to try that are md5 that I can use with odin. I can find all these custom roms in zip format but don't know how to flash to odin when they are in the zip format and not tar or md5. Right now im just bricked and cant do anything and trying to learn how to fix all this.

To properly root your device follow these instructions here ==>

You can not just flash a ROM to your phone like with older phones, due to the locked bootloader. You have to install Safestrap and install the ROM there. You will find all you need to do that along with a link to a Youtube video explaining it all here ==>

ok, I did just like the guide says and applied the tar file. it goes through the whole process but when it reboots it still says "secure fail:modem" in the left hand corner and "system software not authorized by Verizon wireless has been found on your phone please turn off and got to nearest wireless store for help". Im lost....

Stick with my instructions to reset and the instructions to root. I have all the files and instructions you need for root linked in the how to root section in the OP.

I did it word for word, and after boot it still comes up to the system software not authorized by Verizon screen. Don't know how to proceed?
any help would be greatly appreciated because at this point im out 450 dollars.

Took it too Verizon and they said there is nothing they can do but give 178 dollar gift card...anyone here have any other ideas? Followed the rooting guide here, updates were turned off, don't know what went wrong

Did you re-partition using the pit file when trying to go back to stock? This doesn't make any sense. To the best of my knowledge, even tripping knox won't result in this ...

Yeah I did. Don't know what to do...I seem to be the only one that has had this issue. My question is, what did I do to wrong to make this happen? How do I prevent it when I get a new phone? It seemed to happen after tethering using x tether on xposed? Is there an issue with xtether ?

No there's no issue there. I run it and have Odined back to stock a couple of times and re-installed it.
Work backwards. Un-install all xposed modules. Un-install SuperSU, towel root and everything else you have added. Do a factory data reset and then try to Odin back to stock maybe? Take it all the way back to NGC
You don't use any kernel tars, just the full factory image tar

LG G2 Secure boot verify error Please HELP !!!

Good Day everyone
I am in desperate need for some help please, i managed to brick my LG G2, and need help unbricking it
I have the D802 International model.
The story so far, it had Cloudy G2 2.1 Rom on, wanted to update it to, Cloudy G2 3.3 , followed the guide on Blogspot, when, you search for "kevin with tech cloudy G2 3.3" on Google
Wiped the partitions via TWRP 2.7, as stated in the video (everything except internal storage), and then installed the KK-D802 bootloader.
After i rebooted, my G2 did not come boot again, it will go on with the boot logo and the words: "Boot certification verify" Secure booting error. will appear for about 2 seconds then just goes black.
Whenever i try to plug in via USB cable, it will detect multiple new drives in windows and accept me to "Do you want to format". in the device manager i can see device being detected as "QHSUSB_BULK"
My phone is rooted as well.
Some sites recommend using a linux way, but i have been through countless forums, and not sure which way is the right
Please please i need some help unbricking it, and willing to donate to the successful user advice / tutorial of unbricking it.
Thanks for reading and in advance.

Had the exact same issue, I believe it's caused by corrupting the internal memory (multiple causes for this).
Don't freak just follow http://forum.xda-developers.com/lg-g2/development/tools-srk-tool-useful-toos-lg-root-twrp-t3079076 (there's a video guide at the bottom, but it's pretty straight forward).
After that follow http://forum.xda-developers.com/showthread.php?t=2432476 to get it back to stock and work from there.

Good Day everyone
Thanks for all the advice and help, wanted to update the thread to solved, but things went a bit hectic at work during the week.
Anyways managed to get my phone working again, and restored to original state(thank God).
Basically followed a guide i found on Youtube, used the LG Flash Tool 2014 to flash back to Kit Kat stock, and then from there i rooted and used Auto_rec.
Found a guide on Reddit for Cloudy 2.2 install, flashed correct KK-Bootloader, and restored my Nandroid backup (which strangely at first did not work when restored via TWRP on stock Kit Kat, got the same Secure boot error)
Restored only data and system (everything except the boot) and my phone was back to it's original state.
Hope this helps anyone in the same situation.
PS: I was stuck in some boot loops, so had to format my internal memory as well.
Peace
