Hi,
You can use this guide http://zidroid.com/how-install-flash-twrp-custom-recovery-on-lg-g4/
For reference, I always seem to have an issue with step 6 (command "fastboot flash recovery twrp.img"). Instead i use "fastboot boot twrp.img" or "fastboot boot recovery twrp.img" (I can't remember which). This has the benefit that it will boot into twrp but won't have flashed it. You can then take a back up of everything stock before using install to install twrp from within itself.
Regards,
Ravi

Thank you for the answer

[Q] Stock Unrooted Desire Z restarting

Hi, I have a Desire Z that keeps restarting itself almost. I can go as far as opening the app drawer before it restarts again. I'm trying to figure out how to fix it or at least recover/backup files from the phone. Can anyone help?
if I flash a custom recovery/root my phone, will that wipe everything on the phone? I am mainly concerned with backing up all my data. The stock recovery shows phone with red triangle, dont know what that means. Please help.

If i remember correctly you can do this by holding down the S button while booting the device.

Tried booting in safe mode, still the same thing. The phone reboots as soon as the launcher is done loading. I think its an issue with either the launcher or there's a conflict in android/sense which is causing a crash. Still trying out different things.
Edit:
Since I have never recieved OTA update for this phone, I believe I'm still on RUU_Vision_BellMobility_WWE_1.34.666.1_Radio_12.28 b.60.140e_26.03.02.18_M2. I have adb set up, is there a way to confirm I can safely S-OFF/root?
Edit 2:
Did a factory reset - no changes, still rebooting
Edit 3:
Seems like USB debug is not turned on my phone, I tried my gt-i900 and can see it using adb devices but not when i plug in my Desire Z
Edit 4:
While in stock recovery, I have a phone with a red triangle, and adb shows device as offline. At least I can confirm that adb is working with my DZ. Now to figure out how to push files to it
After the factory reset you won't get any of your data back, but you need an os so you can root. Find the latest ruu for your phone and fllash it through fastboot or bootllader as a pc10img

Can I flash the ruu from an external sd because I cannot copy to the internal memory as the phone doesn't stay on long enough. Thanks
Nope, but you can use fastboot

is fastboot the same as adb? for example, when using gfree do i just replace adb push with fastboot push?
Edit: Nvm, figured it out, now I need to find the proper RUU for my phone, which one should i be using?
Edit: Stupid question above, I already mentioned which ruu i was using so I'll try to flash that. brb
Nope, adb is similar to fastboot but different, read my thread on it as if you own any HTC phones (and various others) its a must to learn. You'll find it here in the general section
You will use fastboot not to root but to flash the latest ruu as you need to have adb access and this means you'll need an os that's working.
fastboot oem rebootRUU
This is the command you will run in cmd or terminal but read up on my thread to understand more

I read your thread, very helpful. I had one question though, do i need an oem ruu to run the command fastboot oem rebootRUU? I'm just confused as to whether I need to root first, flash the hboot, or flash the ruu. I also have the stock recovery so when do i flash the cwmr?
1st you need the ruu, I believe nipqer has most on his server found in one of his threads. You will use fastboot to flash this. This will rewrite all your firmware and software and hopefully produce a functional os so you can get adb access
Once this is done, follow the xda wiki to root your phonephone

Finally! Phone boots up and I have adb access. Followed the instructions (ran into some trouble with chmod command returning "Operation not permitted" - had to start all over again with fastboot flash oemRUU) and now I'm rooted. Time to install some custom roms. Thanks demkantor, your fastboot tip and thread got me through this!
I'm glad you're up and running! I suggest to check out my is this a brick thread as it may help know what to look for if you run into trouble in the future
Either way, happy flashing!

adb only works in os and recovery, fastboot is when in bootloader
You are best off to root with gfree but at this point you need to return to stock or at least get a working os and downgrade radio, so for now flash a ROM in your recovery and the extract the kernel and flash it in fastboot
fastboot flash boot boot.img

i've got only ruu.exe for this, i can't find stock rom in .zip file
i forced ruu from fastboot and it fails after sending img in ruu, signature, error 155 in ruu
after next couple tries i've got 130 error, wrong Model ID Error
You don't have superCID so most RUUs won't work, at this point take any ROM, flash it in recovery, extract the kernel from this ROM .zip (boot img) and the use fastboot to flash it
fastboot flash boot boot.img
This will get you a working os
Now you need to follow the guide to downgrade in order to allow gfree to run its exploit as the radio version you have is too high
All this can be found in the thread I linked you to but feel free to ask further questions as well

status on top bootloader is relocked
Can't see your link
You may have ran something that locked your bootloader which will make things very tricky unless you still have a custom recovery. If you don't you will need to fine a ruu that is a newer version than you have now. See the stickies in the Dev section here for vision ruus and use the newest to be flashed through bootloader

TWRP recovery? If so flash a stock based ROM in there so you don't need to flash kernel, try virtuous g lite

Hold on, slow down a bit, don't keep flashing just anything or you could put yourself in a harder place than you are now
So you do have twrp recovery right now correct? And you flashed virtuous g lite and got this error correct? If so let me know, don't do any thing else, and we will find a ROM that will flash that has stock kernel

Sounds good, just let me know if you want to try and fix your phone later on. The boot from SD is kinda a last resort but if your OK with it

i want fix it i don't have to, but i really like it and i would like to fix it anyway. I can't make a root and gfree because i've got errors in adb, something about eMMC
That's because your kernel has been manipulated to allow os to run from SD rather than emmc. I don't believe you will be able to use gfree while doing this.
If you want real time help I would suggest going to freenode #g2root
There you will often find people to help you in real time, not to mention some of the most knowledge about the vision

i try on #g2root and nothing. but i know my cid HTC_32, ruu dont start, i dont know what else i can do with it
Well you often need to wait around a while on #g2root or keep trying back if no one is there
What is current info on bootloader screen? Are you still unlocked?
Why not try and flash a ROM ROM through recovery and then use fastboot to flash the kerenl like I mentioned in my first response
Then with a functioning os you can begin the process to root and gain s-off with gfree
i try and won't start. i wait on g2root but one person try to help me and nothing with that
Pm me your Skype Id or some way of messaging you and when I'm @ PC I'll let you know

[Q] Flashing TWRP Update without loosing data?

Hi there,
I just tried to flash a newer version of TWRP (to be able to write NAND backups on exFAT formatted external SD cards) but after that I could not boot the system. I had to flash a system rom again and restore from titanium backup.
After that - for whatever reason - I had the old version of TWRP recovery installed again..
So, is there any way to update TWRP without getting the same problem again?
Thanks in advance and best,
Julian
Can't you update recovery by using the goo manager app?

Nope, it just says "recovery has been installed" - but nothing happened :-/
just do fastboot flash recovery openrecoveryXXXXX.img ? everything should be the same but your recovery should be updated
einfach mit fastboot flashen dein rom bleibt unangetastet.
You could try TWRP Manager
Well, I'm not quite sure what I did (or did wrong) in the first place - but it works.
fastboot flash recovery did the trick.. now.
Thank you guys!
Best,
Julian
I've tried to flash TWRP latest for the M8 via terminal using the command which is shown on the TWRP website but it gives me an error message saying read protected or something, my bootloader is unlocked but I'm trying to flash TWRP and root, I don't use PC /Laptop so using terminal on my phone the only way unless I go to Internet cafe, anyone successfully flashed TWRP via terminal?

Your going to have to either get fastboot working get your bootloader to read PC10IMG.zips from SD card,
Both of which I gave instructions and a bunch of links in the other threads you created, these are important things to have working so when you find yourself in this position you can easily fix it. I suggest going through your past threads and look over the instructions and links I sent you

ok bro...from windows 7...my device is listed in "fastboot devices" cmd command ....
so..how to flash a recovery..?
i put cwm recovery img in c:\recovery.img (i named it as "recovery")...
so, when i flash it via this "fastboot flash recovery c:\recovery.img" command, its shows this
sending 'recovery' <3552 KB>...
OKAY [ 0.608s ]
writing 'recovery'...
FAILED <remote: not allowed>
finished. total time: 0.612s
so how to flash it? do i need another recovery img?
You need to get an engineering bootloader, which in the state you are in now you will need to get those PC10IMG.zips to flash, in that fastboot thread there is one I made, post 30, that will give you an engineering bootloader

That should be the one, but you currently have a shipped bootloader so in your situation the only thing you can do is flash it via a PC10IMG.zip
I know you were having issues earlier, try other SD cards, try reformatting them, this is the only thing you can do right now

so which PC10IMG needed? is that working where from i get the eng bootloader ?
i put "PC10IMG.zip" into another 2gb sd card and boot into bootloader and then 3-4seconds later some green popup showing, like this
SD Card checking..
No image or wrong image!
Loading....[PC10IMG.zip] etc....
...so what can i do now?
One thing: i tried this same method now with my friend's desire z....but same thing happening...
Finally , i upgrade bootloader into "0.84.2000" via this "fastboot oem rebootRUU" and "fastboot flash zip PC10IMG.zip" trick!!!
and flash Recovery and i am all right now!!!!!!!!!!
Adb, fastboot is a must for every Android user.
Everytime when someone tried to help you, you didnt wanted to go for adb or fastboot.
And now you can see, adb and fastboot helped you... So always go for them and atleast learn adb and fastboot commands.
Anyway its so good to hear that you overcame your problem...

is there any CWM Touch or non-touch for KK roms..? because, NeverGone\RU's recovery isnt good, crashing...and cant flash purekat and other some roms...
No, I don't think at present there is any touch CWM that is compatible with KK ROM.
If your touch screen is fine, why don't you use 4EXT.? It's a great recovery.
Also you can try TWRP recovery by demkantor, it also supports KK.

Glad all is working for you Alex, your probably best off to stick with 4ext classic (nontouch) recovery. Then if you want to flash KitKat ROMs you'll just need to edit the updater-script yourself to get things working
I won't be near a PC all day so can't help you do it but just search for guides on xda or Google, not too difficult
