Okay looks like the ls996 isn't as downgrade friendly. Something about a different bootloader. I basically can't enjoy a phone anymore without root so if a 5.1.1 method doesn't come quick I'll have to sell this one and get one that hasn't been updated.

[Nexus 5 Q&A, Help & Troubleshooting] BrainF**k:
Hi Guys,

I was playing Clash of Clans on my Nexus 5 when my phone ran out of battery. I charged & switched on, from there my phone was stuck at flying dots. What I tried,

Hard Factory Reset

Wipe Cache Partition

Then again re-booted it, still again stuck at flying dots. Then used TWRP recovery, but still it stuck at flying dots.

After this little stint with TWRP, finally flashed Lollipop version5.1.1 (LMY48B), but again it stuck at flying dots.

But this time, I received ./cache partition error. I have used the steps mentioned in this link:

http://xdaforums.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701

+ fastboot flash cache cache.img mentioned in here:

http://androidforums.com/threads/nexus-5-stuck-in-the-start-up-screen.887612/

Though cache partition error got removed, but still was stuck at the same situation. Finally, roll-backed to KIT-KAT, this time it worked, but Camera, Gallery, Play Store was continuously crashing. When I opened the gallery it showed no SD card, then I downloaded few files + downloaded OTA update, they both got downloaded. So, I think internal memory is my fine, don't know the possible reason of this error. One more thing, my sim card was also not readable.

Few hours later, I again flashed my phone to Lollipop, then again got stuck at flying points.

PS : Apologies for making this post long, but just want to tell the methods I tried.

All -

I flashed my Xperia ZU GPE with the CM12. I keep getting 'process.acore' errors randomly. Now when I tried to restore to stock, I am getting 'E: signature verification failed" error. Not sure what to do next? Advice please? Thanks in advance!
[Sony Xperia Z Ultra] egzthunder1:
Thread moved to q&a.

To answer your question, you need a different recovery. Try with DoomLord Advanced Kernel...

There are two rules in life for being successful:

1. Never reveal everything you know;

2.
[Sony Xperia Z Ultra] adfurgerson:
If you want to try a possible fix for your CM install, try clearing data for contacts and contacts storage in app manager.
[Sony Xperia Z Ultra] z3atl:
Thanks for the reply. When the process.acore happens, clearing the cache of the contact storage does not help at all. I had to do a phone reset every time.
[Sony Xperia Z Ultra] egzthunder1:
Have you tried clearing data? You mentioned cache. The few times I have run cm and have gotten the acore error, it was because of dirty flashing. You might need to clear data as adfurgerson suggested.

There are two rules in life for being successful:

1. Never reveal everything you know;

[Sony Xperia Z Ultra] z3atl:
Before the flashing, I did wipe everything (media, cache, etc.) from the Cyanogen Recovery. It is the same result.
[Sony Xperia Z Ultra] RealityFails:
Did you flash cm12 or cm12 gpe? If you flashed a cm12 you may need to flash an ftf stock ROM. Im on non gpe so I can't be 100% sure but I'd try. Look for gpe ftf
[Sony Xperia Z Ultra] adfurgerson:
There isn't a GPe ftf! DO NOT FLASH ANY FTF it will cause a hard brick that cannot be fixed. You will need to look in the GPe section for return to stock. The update has to have the verification edited out and be flashed with a custom recovery.
[Sony Xperia Z Ultra] RealityFails:
Like I said I wasn't 100% so relax.

But he should be in the gpe section.
[Sony Xperia Z Ultra] adfurgerson:
Like I said, the only thing that can be done with an ftf on a GPe phone is cause an irreversible hard brick so when I see it mentioned I get worked up a bit.

There is only a development section for GPe which is I'm guessing where this was moved to Q&A from.

Sorry if it came across as rude, it was more of a reaction to protect someone from screwing their phone up.
[Sony Xperia Z Ultra] z3atl:
I appreciate the replies.

Yes the ROM was GPe. And I was in the GPe section following the guides trying to to back to stock. Currently, I am on CyanogenMod Version 12-20150401-Togari- GPe.

I can get into fastboot.

I can get into Cyanogen Recovery.

I can NOT get into stock recovery.

I'd like to go back to stock 4.4.4 then maybe upgrade via OTA to 5.0.

What is the best route to do this? Thanks very much!
[Sony Xperia Z Ultra] egzthunder1:
I would say that the easiest would be to flash via fastboot into official gpe and then try to downgrade via custom recovery (DoomLord advanced Kernel)

I'm stuck on "fastboot oem device-id" command in cmd. Everything up to that point goes smoothly.

command line says "waiting for device" and the phone screen doesn't show phone ID, but gives me options 1-3. 1 being to show device ID, can't remember what the other ones are now. But I can't select "1". What am I doing wrong?

I have USB debugging on, also the OEM unlock is checked in development options.
[G4 General] SAO:
unplug your device, if you can't restart it, by keeping your finger pressed for 10 seconds on the power button, take battery out.

Once you put the battery back in, restart the phone, plug in the phone in the computer, restart the CMD, and start the procedure again. :

2. launch your CMD and type:

adb reboot bootloader

your phone will reboot

3. type this to get your Device ID

fastboot oem device-id
[G4 General] Eclap78:
I've tried this a few times now, same outcome, same thing, don't get a code, only get the 3 options and the power off 10 second thing, which doesn't work btw, have to pull battery every time :(
[G4 General] SAO:
The numbers should show on your CMD window on your computer not the phone.

If the CMD window only shows "waiting for device", did you try to shut the CMD windows?
[G4 General] Eclap78:
ah, thought they were supposed to show on the phone screen.

not sure what you mean by shutting the cmd window? I just get stuck on that "waiting for device" message in cmd, at which point I unplugged the phone, did a battery pull and tried again. I've tried about 5 times now, I double checked everything, have all the drivers installed etc.

Oh, and I do have the h815 EU version of the G4. I'll keep digging.
[G4 General] Pyrres:
Could someone try out netflix, camera, divx files, YouTube and all the things that people were afraid of loosing. I for myself would really like to root but I dont want to loose any functions by doing that.
[G4 General] SAO:
I have no issues with Netflix, divx, camera or YouTube.
[G4 General] AhsanU:
Just a reminder that this does not work with all H815's as of 6/5/15. I think those of us that got a non EU region specific H815's get stuck when requesting a bootloader unlock from LG. Most of us are getting "not found suffix" when trying to submit the IMEI# and device ID. Note: trying different internet browsers does nothing, so don't bother.

We'll have to wait for LG to either approve all region G4's or another method. Cheers for making a guide though.

Answer yes to factory reset and you get to twrp. This is how g4 boots to twrp

I pressed yes twice and it showed the little android then rebooted. Does this mean I didnt properly install TWRP?

Last week my g4 bricks in case of hardware issue. Now i got a new one from warrenty. It comes with h815 v20d on it and is from vodafone germany. Bootloader unlock was easy but when i tried to boot into recovery it failed. No reaction from the phone only reboot to os. Fastboot boot twrp.img didn't work also fastboot flash recovery twrp.img didn't work... So i tried twrp for h811 and then fastboot boot works and then i was able to flash supersu... Just in case someone is in the same situation... This solution works for me. It was the new twrp 3.0 for h811

My computer shows me the name of the file as twrp.img.mid5, and when I place it in my phone and in my computer and cmd the folder, it says "no error" or "can't load" or "no file or directory" etc. And if I remove the "mid5" it becomes a legit image file but when I try to boot into TWRP it says "booting.. Failed (dtk something)".

Also, I can only cmd the folder on my pc but not on my storage, there's no such option to do that on my storage.

After some trouble i managed to make everything right.

This method works fine on MM v20c, only difference that you need to flash latest supersu (in my case 2.71 beta THANKS member the-eraser for posting that) instead the one in tutorial. Flashing that old Supersu gave me bootloop.

Only thing that helped me recover my phone was flashing v20c kdz via LGUP from this site http://www.android-hilfe.de/thema/android-6-zurueck-zu-lp-android-5.733674/

THANKS member dolasz for this link.

just plugged it in by holding volume up and click on update and browse to downloaded kdz.

After recovering my phone i did all according to SAOs tutorial and flashed supersu 2.71.....no bootloop. Flashed TWRP via flashify.

Hope my expirience helped, GG

Guys, I need your HELP!

This afternoon I decided to unlock the bootloader on my H815, are passed 2 hours but I'm still unable to get Device ID.

I've installed first the latest version available of LG Mobile Driver (4.2.0), then 3.14.1 suggested into the OP, then the ADB Installer, I've tried also installing LG Bridge, the latest Android SDK 2.3, Minimal ADB and Fastboot from here : result is always the same, after the first command to reboot in fastboot mode the device is recognized also typing 'fastboot devices' but if i put 'fastboot oem device-id' I've got ALWAYS the message.

I've tried both this tutorial and the official from LG http://developer.lge.com/resource/mobile/RetrieveBootloader.dev

I also ran as administrator with the right click, or started a new command window from the folder of Android SDK, or also copied the 3 files needed as suggested from LG into a new folder and moved to the same using the 'cd' line, without success.

My OS is Windows 7 Professional, to start from the cleanest setup I've also unistalled and installed again the drivers with a reboot between the setup, please help me because I don't know more what I could do to unlock the bl. :crying:
