Are you buying online or in person? If your buying it online just check the sellers feedback and return policy. It's all you can do. There's a lot of scammers that sell frankenphones. Especially avoid aliexpress, buy from a reputable vendor.

If your buying it in person you check the status of the IMEI from a website like this to make sure it isn't stolen or anything or use this app

Hi to all. Friends I have questions

1) some information about clean and dirty flash

2) which wipes should I do before flashing a Rom and which wipes should not?
[G2 Q&A, Help & Troubleshooting] SergioRmz:
1) Well, basically you have to make a clean flash every time you're flashing a ROM for the first time or when the ROM you're flashing has a different base. Dirty flash is used when you don't want your apps information to be lost and can be done when updating into the same ROM unless stated the opposite by the OP.

2) Wipe everything except of internal storage, since it will erase all your information including your ROM.
[G2 Q&A, Help & Troubleshooting] sakis_the_fraud:
I didn't know that about the ROM update. :good:

are there any ROMs that use at least this "update method"?

At least you flash a small file, not the whole ROM again...
[G2 Q&A, Help & Troubleshooting] d00lz:
Look up CyanDelta. It's a good alternative if you don't want to constantly download the updates as a full ROM zip. Instead you download a small patch file which is essentially the difference.
[G2 Q&A, Help & Troubleshooting] Sunandroid:
Maybe I should add some things, just to avoid confusion.

1) Dirty flashing means flashing (without wiping anything before) and afterwards just wiping cache and dalvik. So all your data is still there but your ROM is up to date. Clean flashing means wiping everything (except internal storage) and flash then. This is highly recommended if you are switching ROM (e.g. from Cloudy to CM or something like this) and erases all your apps and their data. If you have issues after dirty flashing, others don't have, a clean flash is recommended too. The issues might come from old data which interferes with the ROM in a way it should not.

2) You saw it above. You always wipe dalvik-cache and the cache. Everything else depends on what and how you want to flash.
[G2 Q&A, Help & Troubleshooting] sakis_the_fraud:
It's a shame that CyanDelta works only with CM, Paranoid and Omni.

I try to avoid CM because i had issues in the past, Paranoid and Omni aren't supporting the G2 any more, they still have KK builds only.

Hello guys

I m owning a LG G2 f320s from yesterday and before it I used LG Nexus 5 for 1 year. The problem with lg g2 is I can't enter into the recovery mode I tried with power + vol- key but not successful. then I tried with vol+ button and a Korean language appeared as its a Korean variant but nothing happened. If I hold the buttons it reboots repeatedly.

So can u guys can teach me how to enter into the fastboot on my LG G2.

THANKS
[G2 Q&A, Help & Troubleshooting] Sunandroid:
Official LG drivers worked fine for me.

No way to get into fastboot. And no way to get into recovery unless you have installed a custom recovery. Describe us, what you have done, and what you want to do with the phone next. I/We'll show you the right direction. ;)
[G2 Q&A, Help & Troubleshooting] d00lz:
Try the Universal Windows ADB Driver by Koush. The original drivers you installed might not have been complete.

Don't bother uninstalling the original drivers.. just overwrite them.

"If you do any Android development on Windows, this will be ridiculously handy. Every manufacturer ships their own ADB driver on Windows, so getting new devices running on ADB is a royal pain. I've compiled a list of most phone vendor and product ids and rolled them into a single driver."

You realise you have to release the PWR + VOL DWN buttons when you see the LG Logo and hold them down again.

Holding PWR + VOL DWN by itself without letting go and repressing won't boot you into your Recovery.

Alternatively you can enable run the adb reboot recovery command.

The Korean screen you saw was most likely Download Mode, not Recovery Mode. However you haven't stated if you had your device plugged into your PC when you did this.. so can't confirm.

Because you haven't told us what Bootloader you're currently on you may have to access Recovery by holding PWR + VOL DWN, and when the LG Logo appears let go and switch to holding VOL DWN + VOL UP.

For some extra reading, refer to [GUIDE] New Root Method for LG Devices

[G2 Q&A, Help & Troubleshooting] d00lz:
Yes sir, right away sir.. however, you have still failed to tell us the current state of your G2. So I will assume you are 100% STOCK UNROOTED running KK :rolleyes:.

Download, Install and Run TowelRoot.

Now you need Custom Recovery. The easiest way you can do this is by Downloading, Installing and Running AutoRec for the F320S.

Once you've successfully installed TWRP, congratulations.. your phone is ready to flash any custom

[G2 Q&A, Help & Troubleshooting] Sunandroid:
Back up your ROM in TWRP, delete the app and see if the device still works fine. If not, just restore the Backup.

Make a CSE flash with the LG flashtool. Custom recoveries usually don't wipe everything what stock recoveries wipe during a factory reset. But after a CSE flash everything should be gone. Including any custom recovery.

connect it to a computer while holding the vol+ button. Don't press the power button, if you want to enter the download mode.

Thank you for your advice. XPrivacy seems great, but maybe complicated, if I believe the last words from the developper :

"If you want to protect your privacy for applications which were installed before XPrivacy was installed, you will need to rebuild your system from the ground up (like factory reset, install XPrivacy and install/restrict applications one by one)."
[G2 Q&A, Help & Troubleshooting] Sunandroid:
So this is why he writes this: Every Android device has a hostname. And this changes with a fresh install of a ROM. So if you don't reflash the ROM, it will stay the same hostname. So apps that saved your data until now, will keep the data they already have. But if you get a new hostname they have to begin at zero again. You see the clue?

xPrivacy still works, no matter if you reflash your device or not before installing.
