The biggest problem that Moto G5 users are facing is the problem of IMEI and/or bootloader loss after returning back to the stock firmware.
Why was my device hardbricked?
This is the step by step how to Break your device: (do not do this)
Install an custom rom
Return back to stock firmware
Flash stock bootloader and recovery
Update the software in stock rom
And then the magic happens. Your device dies.
Oh my god, what do I do for this doesn't happen with me?
Simple: Don't return back to stock firmware using fastboot when your bootloader is unlocked. If you want an stock rom, flash this debloated rom using TWRP (32 bits)
My device is hard bricked. What do I do now?
Feel. Reflects. Cry.
Our community of developers are studying the cedric and looking for solutions to fix the Hardbrick, but this for now is a nightmare and there is no solution. Sorry my dude.
OK, and the IMEI?
If your device does not die in the middle of the bad path, you are likely to lose the IMEI of the device and not be able to make calls or use 4G.
How to avoid this?
Backup your IMEI. How? idk.
And the how to avoid this is the same for how to avoid hardbricks.
I lost my IMEI. And now?

So basically turning a provider locked phone into the european open D802?
edit: another question:
If i do a nandroid backup of my stock LG rom, is it possible to just do a nandroid back up, install stock recovery and basically "lock" the phone without the hassle of having to go through the longer "unrooting" guide?
thanks in advance!
It should be enough to follow the "back to stock rom" thread http://forum.xda-developers.com/showthread.php?t=2432476 , this will change the current rom with a stock LG rom using LGs own tools.
Partially no, it flashes based on IMEI region. You want to flash a EUA KDZ. Then disable OTA.
I apologize for the lack of knowledge. Ive flashed all my phones so far sgs 1, nexus 4, galaxy nexus,htc one x and what confuses me about this phone the most is the kdz files.
My phone, for example, is a provider locked d802 - provider being www.a1.net
(Austria)
Now i followed the link you showed me but it only shows me open european d802 and some from germany files fir download. Would it be safe to flash those when reverting to stock considering i have a d802?
If i want to flash my provider's rom, how do i go on to acquiring those files ? Just incase of phone issues and i have to send my ohone in. Would it be as simple as flashing my stock nandroid backup, flashing stock recovery and typing fastboot oem lock in cmd ?
Im sorry for all those questions, while im quite confident i would get it done, i just like to acquire the basic understanding needed before i start anything.
Not to say i dont understand the effort put together by those who made the threads (how to flash/revert to stock etc.) But the threads to a certain degree are limited to just a simple how to when they could maybe use a little bit more detail.
Thanks in advance guys! Looking forward to rooting this thing

If by unlocked, you mean allow you to put any Sim card in it and it work, no I don't think there is a way to make that work. Roms deal with a totally different part of the phone than the carrier lock. If you mean boot loader unlock, that would specific to your phone model and flashing one from a different model could do nasty things to your phone. I would suggest finding the exact forum for your phone model (I.e. at lg g2, international g2 etc).
They should have all the info you need, and to carrier/Sim unlock your your phone to use on various providers- I would Google "Sim unlock *insert phone name here*) and read through til you find a site that will work out.
Edit* I just saw your provider, u "should" have an international version and you should be able to easily bootloader unlock, root and flash the phone. Be sure to read carefully before attempting anything though.

Oh.. So although im provider locked and own a d802 i basically still have the international version and therefor should follow the d802 international guides/should be able to flash d802 roms?? I really apologize if my questions have been stupid so far. Just i am very cautious. Thanks a bunch though.
But can you answer thr nandroid part (in bold text) ? Basically reverting to stock with nandroid backup, flashing stock recovry und locking the phone in fast boot. Is this doable on the g2? Thanks a lot once again appreciate it

If you unlock your boot loader and install a custom recovery like clockwork mod or teamwin recovery you can then make a nandroid of the exact stock ROM to restore back to. Relocking the boot loader is separate but usually fairly easily done. More often than not, the steps to relock the boot loader are laid out in the same thread to unlock it.
Be very careful, most of the time, once you start changing things you NEVER EVER want to accept an ota update from lg until you return EVERYTHING back to stock.
My recommendation would be unlock, install twrp and flash a custom ROM. That way you won't ever be asked to do an lg update, and most custom Roms end up being as stable or more so than the software that came on the device to begin with.
Or to return to total stock easier, most phones have a "factory" image that flashes in Odin or some other similar software meant for that device. It will erase everything, remove root and relock the phone all at once I believe. Just remember to read everything at least twice, and try to totally understand exactly what you are about to do.

Heya,
I need to returns my phone to as-purchased-state, which means if I am not missing anything - unroot, stock rom, stock recovery
I have rooted the phone, installed custom ROM (cloudy) and TWRP.
On my previous phone, samsung s2, the download mode had a flash counter that indicated how many times I flashed a rom.
On my LG G2, the download mode just says "rooted".
1) So where do I get a stock rom from?
2) Where do I get stock recovery?
3) How do I wipe any evidence of root?
4) In what order do I need to do everything?
I did google and came up with some of these answers, but I put my trust in XDA and hoping I won't f*ck my phone up by doing something in the wrong order.
Thanks!
Sorry this isn't an answer, but it might help you get an answer.
You may want to remove the part where you are admitting to warranty fraud.
Even though this is a hacking forum, people still disapprove of it.
Also, this might be what you're looking for:

Use the kdz method to return to stock. Its in the dev forum. You need the drivers for your phone, the kdz firmware, lgflash tool. All can be found in the dev section.
Can anybody help?I am S Off. Unlocked. Rooted. I am currently on Nu Sense Rom. Need to get back to stock for warranty purposes. I try flashing the Verizon zip and get mismatch issues. 7 RU CID FAIL. Thanks for your help.

Did you make a backup of the stock system image before flashing a custom rom? I haven't tried going back to stock any other way, but I'm fairly certain that the only way to RUU back to stock is if you have a completely stock copy of your system image to restore in TWRP.
Out of curiosity, what issue are you having that require warranty service?
I'm also having trouble finding a guide to this; I've bricked phones in the past, or had issues with reverting to sell that ended up costing me 3 hours of troubleshooting.
Basically I've now found that Android Pay is something that I wish to use again; and with the N update for VZW coming out very soon I might as well go back to full stock with my bootloader locked again now that the main reason I went to s-off/unlocked was for N.
Anyone know where the guide is? If there isn't one, I will outline the steps that I think I need to take, but could use some help to make sure I don't jank it up.
1. Get the RUU from the stock ruu thread.
2. Flash said RUU
3. Factory Reset
4. ???
5. Profit?
As you can see, I'm missing the parts where I re-lock the bootloader, change the tamper flag, fix potential LTE problems (I've read that might be an issue), and whatever else might need to be done to full revert it to legit VZW.
If it matters; I have a (rooted) stock backup from 1.85.605.8 I can flash to make this easier, as I recall having to do that for prior HTC phones (I think).
Okey I'm on ls997 sprint, but using (perfectly fine) the old deodexd us996 rom (dirty santa'ed'). I do find hateful the corrupt message each time power up or reboot. I couldn't find ready decision of removing it for any other similar device to v20 that way I declare I will donate anyones work and time if he shows me the light. I do accept the possibility of bricking my phone. Would rather brick it trying and buy one than using it with this message. Also never gonna use stock out-of-the-box rom because all the bloatware etc so this solution is not fine for me. Highly appreciate any help.
That message will stay on if you want to be rooted unfortunately
no clue if possible: can you loose root in order to remove the message (somehow) while keeping the custom ls996 rom(on which the device already is) because I may not do any more changes and new roms. I don't make use of the root did it only in order to flash custom rom and loose all the bloatware and sim unlock (switched sprint).
It's there because dirty Santa had to flash a debug bootloader so We could even have root ...and the kdz for our phone hasn't been leaked... So just enjoy being able to use it there is no changing it right now...on one of the nexus they did it by changing a img file but don't know where or what phone.

The message is located in the bootloader and can't be removed. The only way to get rid of the message is to return to stock and lock the bootloader.
Thank you for answers.
I do understand this won't work for us https://forum.xda-developers.com/ne...-change-bootlogo-images-imgdata-tool-t3240052
I guess I will just get used to the message best solution :angel:
need someone to backwards engineering the Aboot and either replace the image with a all black image or remove it.
both are extremely risky as the aboot isn't a playful environment and can cause full hard brick.
LS997 doesn't have a KDZ to restore so i'm out for testing on this one sadly. Its been done for other devices in the past but its not a just open replace close deal.
Hi there! I've always been a Samsung user and I'm familiar with chainfire rooting method, Odin, the damn knox and all the tools that people need to achieve the beloved full control of our phones.
Let's go straight to the point: I need to buy a new phone for a friend of mine and the P9 Lite seems the most complete and suitable but I've read that if you unlock the bootloader and root it you obviously loose your warranty. The phone is unrootable by flashing a fresh OS image, but the bootloader will stay unlocked, tripping the useful warraty.
Is there any damn way to revert everything to stock in case there should be the need to send the phone to the customer service?
Thanks for the infos!

You can relock the bootloader if you reinstall a stock rom and revert to stock recovery, just fyi... Also there have been reports that the warranty is not void if the issue was not caused by a faulty software. Also if you are new to Huawei, be careful. And READ! A lot of people don't read, and mess up their phone...
Instead of making a new thread about the same issues I'll pitch in here too. What is the safest way to root and unroot in case of warranty? LIke the OP I came from the Samsung ecosystem too but I get the feeling if I don't at least ask about Huawei's one I'll probably **** something up.

Simply flashing stock rom will lock bootloader but Huawei have your data of unlocking bootloader.

Huawei says they "could" apply fee on unlocked phones. Maybe relocking it restores warranty? I tried to ask them but damn Chinese they don't reply.
They could, but the chance of that happening is really low, especially if your device is 100% bricked, and it needs a motherboard swap

If it's hardbricked and bootloader is unlocked and the problem is not related to bootloader or a process you made that requires unlocked bootloader, I think they won't fee you because it has nothing to do with bootloader. But of course a company will always choose cheaper way. If a phone goes download mode or fastboot mode it's already saved anyway.

I wish... I can't seem to be able to save mine, even though it shows up on fastboot on the pc. The phone itself won't turn on at all. I can't seem to lock the bootloader either, anything I flash now seems to have no effect. I just hope the Huawei service fixes it.

If you have access to fastboot mode, you can flash anything. You dont have to flash an img permenantly if you want to save your phone. Use
Code:
fastboot boot boot.img
you can boot your recovery without rooting your phone. You can even open your custom recovery and flash your system.img or stock boot.img.

I tried fastboot flash boot boot.img (and similarly, recovery.img, system.img, any partition I could flash, multiple times with multiple files) but the phone did not boot at all. Not even into the bootloader nor recovery. It was completely unresponsive. Now the phone is not in my hands so any suggestion is too late...
