I tried to unlock my bootloader, following various guides, and kept getting stuck on the "Download Mode !!!" part. I just want to install the latest stable version of Cyanogenmod on my phone since the stock ROM is being a real pain for me (very slow and unresponsive).
I have:
Android 4.1.2
Build Number: JZ054K
Software Version: AME-XXX
I read online that you need the Euro firmware to unlock the bootloader, can I flash the euro firmware and will it mess with my service? I'm confused as to how the firmware affects things since I've read conflicting information. I didn't flash my firmware a few hours before trying to unlock, so maybe that's the problem?
Seriously?
There aren't enough threads and guides for you to read already? Everything you need is already out there on this forum so why start another thread just because you are too lazy to search and read for yourself?
I have read around and have tried a number of guides a number of times. They haven't worked for me and I'm just wondering what i'm doing wrong. Even though all the information is out there, I don't have the experience to understand it apparently. I've spent hours trying to figure things out but i keep reading conflicting info and half-explained steps and now I'm just confused and would like a clear point in the right direction.
So, do i need to reflash the latest firmware, wait a few hours, then try again on a full charge? Or do i need a euro firmware? Which guide should i follow?
I've downloaded a few applications and driver packages and whatnot but if those could possibly conflict with each other and cause problems i could work with a fresh OS. I'm running OS X but i have linux VMs and friends with clean windows installs (mine is all sorts of messed up)

It isn't a question of firmware, the phone needs to have an unlockable bootloader to be able to be, well, unlocked. Here is a list http://forum.xda-developers.com/showthread.php?t=2181581 of P880 bootloader versions. Follow the guide to check which BL your phone has.
Thats obsolete, all versions can be unlocked afaik, either with official method or by fuse editing. No need to keep sim card in,you just need proper drivers
Oh, OK, I didn't know that. But, even better, OP should not have any trouble, provided he follows the BL unlock guide here http://forum.xda-developers.com/showthread.php?t=2224020
Maybe his BL is already unlocked OR is relocked (meaning can't be unlocked anymore).
Its more likely that his drivers are messed up imo.
The fuse editing method should work for everyone, i recommend you give it a try
So the fuse method would be the "BL-unlock.bat" method on that bootloader unlock forum post? I've tried it before, but I'll try it again. The directions only say to run it, is there anything else I need? Now, since it's a .bat file I absolutely have to run it on Windows, right? Because if so I'll use a friend's computer instead of my windows installation.
What are the necessary installations before I run the file? How should I configure settings on my phone? (like what type of usb connection should it be)
There are a lot of things that people expect readers to know but I'm really not very knowledgeable about standard practices for phone stuff so I really need every step. Thanks for helping!
Since its.bat file, you can open it in text editor to see which commands it executes. I'd still recommend to do it on windows machine, other OSs may work but aren't tested.
You need abd & fastboot drivers, plus drivers for our device. It's been a while since I've done it, but afaik you can get proper device drivers via lg support tool.

Also, correct me if i'm wrong I only had stock for 2hours, but also stock needs usb debugging to be enabled or adb won't work?
Yep, afaik usb debugging needs to be enabled
When you are fast enough, it is possible in charging mode wihle the carger animation is shown. But you have install adb driver very fast...
So I'm pretty sure I got the bootloader unlocked, I ran the .bat file and it went through everything until the part where it checks to see if my bootloader is unlocked, it just froze forever, so I closed it.
How should I go about checking?
Also, what would be my next step now for installing CM10.1.3? I tried to follow the guide on the cyanogenmod wiki (install_CM_for_p880) (I can't post links yet)
...but ran into problems with pushing it into root with adb. It said I didn't have permissions, so I googled some stuff, but just got myself confused.
Thanks for all the help btw!

you can check your bl status by entering sw mode (phone off, hold vol+ and insert charger) or reeboting into bl (adb reboot oem-unlock)
to install cm steps are:
-install recovery (you can choose either cwm or twrp, it's more about looks than functions)
-download rom zip onto sd card
-install said zip from said recovery, there's no adb involved
Now my personal opinion, I really don't see the point in flashing 10.1, i would go staright for cm11 if i were you
Ok well I think I got things together more or less, eventually I tried to install CM10.1 with the ROM manager app. I forgot to select the options to wipe my data partitions and now I'm stuck in an endless boot loop every time I turn the phone on. I tried to boot from my backup using CWM which I made with the app prior to trying to install, and it gave me an error about an MD5 checksum failing, no matter what I tried. Should I do the factory reset/wipe option with CWM now? What's my best option.
Also why would you recommend CM11 over CM10.1? I don't want to have to deal with a nightly, all this phone stuff is a supreme headache to me.

Factory reset then get nandroid manager app and see if you can restore your stuff with that
CM11 is bugless atm and performance (imo) is way superior
So after a factory reset/data wipe, my phone just booted into CM10.1 and now that's working. And it looks like all of my stuff on the phone is still there (though of course apps aren't installed and whatnot, that wouldn't make sense). Thanks for all the help!
I tried to find a feature list or something to see what exactly is better about CM11, and found out that "stable" doesn't exactly mean stable for CM, and that it looks like a good idea to update, so I think I will try to update to that. Do you know anywhere that has an actual feature list to show me what CM11 does that CM10.1 doesn't?
I recently got rid of my pc and now use a tablet and Nexus 6.
I've only ever rooted using a pc, but i was wondering if i wanted to root and run a rom on my Nexus 6, can it still be done? Im pretty sure running a rom can be, but not sure about unlocking and rooting.
Any info would be helpful! Thanks!
I am unsure if you have a tablet that is capable of running it, or another phone, but this could potentially work for you. I haven't ever used it, so I can't verify if it works, but people seem to be having success in that thread recently.
If you don't have a phone or tablet that has OTG support, or for whatever reason can't get that to work, then you will need a PC. You have to use fastboot to unlock the bootloader to get root or a custom ROM. Once your bootloader is unlocked you have a couple options, but still step 1 is *fastboot oem unlock* (well actually it is to enable oem unlock in developer's options).
As a side note, I would recommend against rooting and ROMing if you don't have regular access to something that can use the SDK tools (fastboot and adb). Even if they are rare, there are situations that could pop up that would require you to have fastboot handy to get your phone back to functional shape.
hey guys, Im a total NOOB to all these things. was using iphone before now shifted to android. Let me start from first. i got a nexus 6 1 mnth bak. So as soon as i got it, i put it for 5.1 update. hours later update got downloaded and i clicked install. then halfway thru the updating it said error and it started to restart. then it kept on bootlooping to the android optmisation screen. I cudnt do anything else. tried doing wipe cache, factory reset- nothing worked. SO i replaced my phone for a new nexus 6.
Now iM Totally scared to update it to 5.1 OTA. iM Ccurrently running android 5.0 build- LRX21O. I Have not rooted my phone. sO Can u please tell me whether i can update to 5.1 directly from 5.0 thru nexus roottoolkit as i dont want to do the hard way by entering commands which i think i will mess it up. or rootkit is just for rooting and unrooting phone? CAN u please give me a guide on how to update it to 5.1. i dont want to root it.
please guys, im a total noob to all this. please excuse if i dont know stuff. i used to jailbreak my iphones and ipad and do all kinds of stuff. but since im knew i dont know many things in android.
thank u so much guys
First thing to do is to unlock your bootloader. That way, if anything goes wrong, at any point, you are almost 100% able to restore your phone again. It's also a good idea to flash TWRP (custom recovery).
You can update through NRT, or as a lot of us recommend fastboot. It's not as scary as it looks, and it's actually easier to mess stuff up with a toolkit if you have no idea what said toolkit does in the background (hint: it's using the commands).
It's a good idea to read, read and then read some more. If you have a basic understanding of things it's easier to get things done correctly. Start off by reading the FAQ-thread, lots of good info there.

thanks for ur reply. Wil do it in fastboot mode only. i will read more about it., One last question. Can i flash to 5.1 directly from 5.0? or to flash to 5.1 i need to update it to 5.0.1( since most of the forums said this). aLSO There are 3 shamu factory images for 5.1 LMY47D, 47E, 47I. Which one should i use?
Unless you're running T-Mobile or Project FI you should use LMY48I. Latest 5.1.1 with almost all the stagefright patches.
Edit: Oh yes... You can flash straight to the latest.

I concur. Get all you drivers working. Figure out fastboot. There are many different ways to set up adb/fastboot. There is the right way or the fast way. Both work. Can always upgrade so the full SDK is available when you get hooked and have to have all the tools. lol There is a thread for 15 second fastboot. It works. Will at least be what you need to learn fastboot. When got adb/fastboot working we can walk you through the commands.

ok guys, thanks for ur replies. I downloaded SHAMU lmy48i (5.1.1). im running 5.0, nexus 6 international version. let me just confirm what im going to do after this is right and tell me whether to proceed or not.
1)downloaded sdk tools. installed it. dint create a system wide directory. i opened platform tools and opened command window and typed adb version and it said android debug version 1.0.32 blh blah.
2)next i enabled usb debugging and oem unlock in developer settings of nexus 6.
3)connected my nexus 6.
4)went to platform tools and again typed adb devices. it showed my device serial number
5)then i have to enter bootloader. type fastboot devices and it should show my serial number.
6) then type command fastboot oem unlock
7)then have to run fastboot reboot
8) my bootloader is unlocked. Now i have to load it in bootloader mode.
9) then execute flash-all.
10) android will update to 5.1.1
thats all ryt? did i miss anything in this?

Looks good. If going to use flash-all.bat make sure SDK platform tools are updated to Version 23+ in SDK Manager. Can also unzip the file a second time and do each image separately. Will find more use for the individual files later.
Looks good.
Quick advice: remember that unlocking the bootloader and flashing the factory image will completely wipe your device. If you've had time to accumulate some data on there that you want to keep, make sure to back it up first.
In the future, if you decide to root or use a custom recovery, you won't be able to take OTA updates (it checks for a tampered system). It's quite easy to update anyway... Just use the same knowledge you've earned doing this and follow prdog1's advice.
Unzip the factory image a second time and flash all images except userdata.img. That way you'll get a nice new updated system without wiping your stuff.
If jumping between roms or doing a major update, it can be good to let the entire factory image flash, though. Just make sure to backup your stuff first...
I'm a bit slow to realize this, but after updating to T mobile's latest 20b firmware (lollipop 5.0x), it lost root. I then tried to root it, using the three methods mentioned here: http://forum.xda-developers.com/showthread.php?t=2732311.
Towelroot clearly doesn't work anymore. The zip file in the above thread couldn't be flashed since there's no recovery operation possible (just showing an android with ! in a triangle sign). I also tried the purpledrake, but the script doesn't run when the phone is connected with all drives installed and adb devices showing the phone. I then tried to get fastboot mode back (to install twrp/cwm recovery to flash the zip file) by following http://forum.xda-developers.com/lg-l90/general/guide-fastboot-l90-d415-t2827825 which I have done successfully before, but then couldn't do it because it requires root (doh!).
So it seems that I just lost my ability to root, unless I downgrade to a stock kitkat (10e?) from tmobile, and then towelroot/etc. assume those work.
Anyone with experience on the stock 20b firmware? Can you root it and how? I'd love to use the beautiful 12.1 Cyanogen that's available here, but the camera doesn't work right on mine. Thus stock 5.0 seems to be the best option. Many thanks.
I got a bit further on the purpledrake method, in that I had to do a clean restart on the phone and connect to usb before the script will recognize. However, it ends up giving a really quick error message after trying a temp root: "your phone is not running a compatible software version. No vulnerable mode detected. Rebooting phone."
Anyway, many thanks to @brossovitch I followed http://highonandroid.com/android-smartphones/how-to-root-lg-g-flex-2-g2-g3-on-lollipop/ and it works like a charm. I can't seem to delete this very short thread so I thought I'd wrap it up with a solution. If it seems a bit useless please remove the thread (or tell me how to do it since I can't find the "easy button"). Thanks.
I've been searching the forum for several hours now. I do not believe the phone I have is a developer edition and I know the bootloader is locked. Everything on it is stock (no root or anything) and it maybe running 4.4 or 5.1, but no longer boots into the OS so i'm not sure.
Ideally I'm just looking for a way to get data off the device. However, if someone could point me in the right direction for getting the whole device up and running again, that would be even better.
I've rooted / installed custom recoveries and roms on many devices before, so I'm not afraid of running any necessary commands.
Thanks in advance for any help and let me know if any more information is needed.
EDIT: Forgot to mention I could not find a place where adb would see the device. The only thing that sees it is fastboot.

I just got my bricked Moto X that wouldn't even turn the screen on and it's now downloading the last released OTA. All my data seems to be intact as well (I haven't used this phone in nearly 2 years).
If fastboot (via command prompt) can see your phone, then you should be able to get it working. The main thing that got my phone to boot was the steps in this video: https://youtu.be/njXQYn53SPc Long story short, you basically have to make a bat file that simulates what RSDLite does when installing.
