Install the Universal bootloader
I've resolved the problem. Found out it's not enough to just Install the model specific modem. You also have to install the Universal bootloader (https://www.androidfilehost.com/?w=files&flid=148464). The guide doesn't mention that, and it probably isn't necessary to achieve unlocked bootloader.

I have the EU version, and running the pixel launcher fine, and pixel dialer, the only thing that doesn't work for me is nearby locations in the dialer.
Its a case of just finding the right apk, also download google wallpapers from the store, else it will crash when trying to change wallpaper from the home screen.

This guide is meant for people that have experience in flashing Android phones. I just consolidated the information from various threads around the web, so it's easier to find.
Advice here works on the latest Lollipop MIUI stable ROM, 8.0.5.0 LHOMIDG for Kenzo Snapdragon version. I tested it myself.
Just to be clear, I am not responsible for any possible problems you may encounter white attempting to do anything mentioned in this post.
1. follow this guide to unlock the Bootloader unofficially ( http://en.miui.com/thread-253680-1-1.html )
2. do not use "emmc_appsboot.mbn" from the above thread, or you will have a bug that causes your notification led light to blink red constantly, while the phone is connected with a USB cable to a charger, or a PC.
3. use "emmc_appsboot.mbn" from this thread ( http://en.miui.com/thread-280771-1-1.html ), or if you prefer, this is the direct link ( https://drive.google.com/open?id=0B6qi9i0uOR-BY21NRGxVN1JiRDQ )
4. install recovery from this thread ( http://forum.xda-developers.com/redmi-note-3/how-to/zcx-twrp-install-twrp-flash-supersu-t3462448 )
That is all. Enjoy.
EDIT: Apps that are safe to freeze with Titanium backup are listed in the attached screenshots. Remember, do not uninstall or remove them. Just freeze them. List updated on 10. Nov 2016
Also, my advice is not to bother with official BL unlock. It's just a data mining operation by Xiaomi. They use it to get your e-mail account, phone number, location and who knows what else... Also, avoid any MI related services, like MI accounts, storages, backups and sync.
After rooting the phone, FREEZE but do not REMOVE any bloat apps. Do not forget to firewall MI apps!
ty for this, although I agree with you they use this for data mining, but unlocked it officialy anyway, because they gave me permission in few hours... Also unlocking only takes like 5sec,
I use dropbox & google stuff so they have my data already
Agreed, but there is no need to add Chinese to the mix
I will post a list of apps that are safe to freeze in a few days, as soon as I finish testing.
List of apps ( screenshots ) added in the first post.
Updated the list of frozen apps. This is as good as it gets, without getting force close on anything.
Thank you. Your thread helped me with the red light issue.
mhm,this method work in miui 8 global 6.12.1 beta? ( dev)
tested and success. thanks you
tested and success. thanks you
@Tomo123
Please confirm, that Using this ROM as base would work for unlocking unofficially?
http://bigota.d.miui.com/V8.0.5.0.LHOMIDG/miui_HMNote3ProGlobal_V8.0.5.0.LHOMIDG_a831ea486e_5.1.zip
And, i plan to use AOSP roms,but please tell me how to go back to STOCK MIUI ROM[without brick] in future if i decide to unlock officially, i have already got the permission, but the unlock tool stuck at 50%.. cant wait more...
Thanks for the help.
Confirmed working.
I'm on MIUI Global 8.2 (8.2.9.99 LHOMIDG) will this procedure work? I just got my Redmi Note 3 Snapdragon variant today and i want to Root it, Xposed it and Enjoy it

Thanks for the reply, i could unlock the bootloader successfully, but i have a problem.
when i rebooted to the MIUI system ROM while in the process to unlock(after unlocking the bootloader),
i could observe that there was no network, my 4G sim couldnt be detected.. And thereafter when i try CM14.1 or RR rom, i get network but cant make calls/sms but 4G data works.
I tried a few Nougat firmwares, but same problem of no calls/sms
I am getting the feeling it all started from the 5.1 MIUI ROM with no network..
So i was thinking to flash the latest global/dev Marshmallow ROM and start over the BL unlock process.. will it help? have any ideas?
And the most important Ques is that the bootloader talked here would even work on With marshmallow ROM for unofficial unlock or not?
Please suggest.
Thanks.
I've tried this guide loads of times now and I'm always stuck with "FAILED (remote: oem unlock is not allowed".
All the info regarding the problem mention to boot into the system and turn on oem unlock in the developer options. But I can't boot with the modified emmc_appsboot.mbn I only get the Mi logo flashing.
Any ideas?
Hi.
Can some one help check my Elephone S7 (4G-64GB) bootloader status? I've tried the code and some apps, but the code doesn't work and the apps some don't work while others say "unknown" .
On another subject, stock rom related:
- After installing twrp and the latest stock rom, does OTA still work? I think it should since it's the same rom just a different recovery, but I would like confirmation.
- I don't know why but on my Elephone S7 the google startup wizard doesn't start. I even got the wizard apk, but it installs and doesn't run. So I'm thinking... (maybe I shouldn't ) can we install open gapps using twrp without any problems?
Thanks!

can anyone help me i want to get rid of geegbuying faulty custom rom and now i cant
can i flash zte stock rom throw xioami flashing tool?
sorry for my poor english
anyone?
Okay, so I've been trying to get some answers regarding custom ROMs for the past few days but I haven't even got one...and it seems I'm not the only one looking for them. So...lay it in this thread maybe we can start something up.
I am on stock OREO B04, phone's software has never been tampered with anything, TWRP, BL unlock and so on.
This is the premise of the thread, not only for me but for other users who find themselves in the same situation.
Oreo seems to be a bit of a hassle right now for migrating to custom ROMs, and this is not helped by the fact guides in the A7 section are all over the place as well, some may be outdated and there's no clear "Don't use this on x.x version" warning.
I am not even going to attempt to unlock the BL until I clear answer on wether it's possible or not. So let's start with this:
-Is it possible to unlock the BL on OREO?
-If not, what stock official ROM should we install in order to successfuly attempt to unlock the bl?
-Which guide or method is the best for doing so? I've found 2, one from 2016 on MM ROMs and one provided by TurkDevs that seems to work on some Nougat ROMs.
Then comes the recovery section:
-What TWRP should we install on a freshly unlocked device, the official releases, or the Nfound custom ones?
-Also, what are the prerequisites for installing TWRP...I hear that fastboot commands are gone since Nougat and that some flashing methods don't work, then I hear somehow you can do it by bringing back fastboot. How? There's only replies saying "type that command in fastboot" but nobody says if they had it or reinstalled it somehow.
Then comes the ROMs section:
-All custom ROMs seem to require a vendor partition as most if not all of them are Treble based. How do we get that to work?
- I am aware of the fact that the ROM threads have a prerequisites section, but none of them redirect you to a guide on how to get those prerequisites working. I understand that it's not the dev's responsability, I am not bashing anyone here, but a little bit of info cleaning and structuring should be in order in this section.
What I want for me and others in my situation is a clear answer on how to proceed, not a "flash this flash that". There's no secret that the A7 still has life in it especially with the new PIE ROMs.
I've recently seen a reply in one of the threads, encouraging the dev of one of this ROMs to not be disappointed by the seemingly low interest in PIE ROMs. I don't think there's a low interest in them, I think there are users that don't want to risk a bricked phone because of outdated guides and unlcear steps.
There's a lot of confusion going around here so I hope this thread will become a source of updated info on what's possible and what not. Thanks in advance!
Hi, I'm not the best person to help you with this since i've unlocked my Axon 7 a long time ago and I can't remember everything but I will try to help you based on my experience and on what I can remember.
Let's go
Starting with the bootloader, I unlocked mine on stock Nougat B09 using EDL Tool (Oreo wasn't even out when I unlocked my bootloader so I don't know if you can do it while running Oreo but just to be safe you should downgrade to Nougat)
It should be quite easy to unlock the bootloader, here's a simple step by step (please anyone correct me if I'm wrong)
- Download the EDL tool from the link above
- Downgrade your phone to Nougat (Using the updater on the phone itself or an EDL Package with EDL Tool or MiFlash - you can find the stock ROMs on @raystef66 's Download Center
- Once running Stock Nougat, turn on USB Debugging and Allow OEM Unlocking on Developer Settings
- Plug the phone to your computer and open EDL Tool (that should reboot the phone into EDL mode automatically)
- Navigate through the EDL Tool using the number keys on the keyboard, and it should be easy to find the Unlock Bootloader option. Unlock it and you should be done.
Once again that's the way I did it, I don't know if this is the easiest one available. You have more methods available like this one
Now onto the recovery situation, I think each developer recommends a specific TWRP version for their ROM's, like for example
@raystef66 likes NFound's TWRP 3.2.1-8 as you can see on his ROM's posts (check the first line in the installation guide)
@OrdenKrieger likes the official TWRP as you can see on Lineage OS 16.0 post
Generally, official TWRP should work just fine with any ROM.
On a recently unlocked Nougat Stock ROM, I recommend maybe an older version of TWRP, like 3.2.1 for example and you can flash it also using EDL Tool.
But when moving to Pie I recommend you use the latest TWRP version or the version that the ROM developer recommends. You probably know this but you can update your TWRP version by flashing it over the current version you have.
Now about the ROM's, the new ones have a Vendor partition so you have to create it when you're coming from Stock (because our Axon 7 doesn't support Project Treble) and to do that you can use @Oki 's PARTY Tool and after that you can flash the ROM normally, using the proper Bootstack and Modem files.
You could also try GSI's but I can't help you with that because I never tried them.
And this should be all.
I tried to keep it simple for now but i can help you further
I'm not the best person to guide you but at least I tried Feel free to ask me something and good luck!
@joaocandeias Well, dang it worked. Everything you described:
-going back to Nougat
-unlocking the bootloader with the EDL tool
-flashing TWRP-
creating the Vendor partition, and installing the new ROMs.
There were a few hiccups on the road, mostly driver related from my previous attempt, but nothing severe or something that would cause the device to brick.
I just installed @raystef66 's ResRemix ROM and it works fine. I'll start testing more of them in daily use and see which suits my needs best.
Thanks for the assistance!

I'm glad I could help
Since you're not the only person with questions on how to migrate from stock to custom, I'm thinking about writing a full post so more people can see it.
Btw what method did you use to downgrade to nougat?
@joaocandeias Sorry for the delayed response, I've got a really f'd up sleeping schedule these days. I'll write the exact steps I've done.
1. So, I first downloaded the B09 Nougat full stock ROM from the download center and tried to downgrade using the normal software updater in the phone (OTA window, local option).
It didn't work at first, I received a compatibility error, saying that the update is for "ailsa_ii" devices, while the device is not(or to be more exact, my device was " " ), which I found odd.
But, I thought that maybe I need the linked versions(like the last Nougat ROM before Oreo) so I downloaded the B10 Nougat ROM, and used the same procedure.
2. I set up the phone as a dud(skip everything, no Google account), turned USB debugging and OEM unlocking on, installed the original ZTE drivers straight from the phone and rebooted it into EDL to proceed with unlocking the BL.
At this point, I had the QUSB_BULK driver stick from my previous use of Zadig, so one quick "uninstall device software" and relpuging the phone go me the Qualcom 9008 driver in order.
3. I started the EDL tool, navigated through it and started the BL unlock procedure.
Once the phone rebooted I was greeted by the password screen.
One factory reset later and repeating the procedure greeted me with the "Bootloader unlocked" message. Sucess!
4.Now for TWRP, Vendor and ROM, got all the files onto the SD card, I flashedTWRP 3.2.1-8 NFound, then, from TWRP, I used the party tool, then flashed the UBv2(at which point it reverted TWRP to 3.2.3, flashed the 3.2.1-8 again with EDL ), modem, ROM, GApps, rebooted, set it up, then flashed Magisk...and everything seems fine.
The only issue I have now seems to be the camera, both stock app and GCam.
Open camera works , has the correct photo and video res, 60FPS doesn't work and the flash seems a bit laggy, but for me it's ok.
The DAC however is there, alive and kicking, Neutron detected the Hi-Res codec at launch and switched to it. It sounds the same as stock OREO to me so it is great, as this was my greatest fear when migrating to PIE. The DAC-AMP combo is like 60% of the reason I bought this phone in the first place.

Thanks! That will help me a lot to write a full guide. You'll be credited, don't worry
And yeah, when you migrate to custom roms you'll have to sacrifice camera quality and functionality and also a bit of speakers sound quality (all dolby atmos ports I tried are quite buggy and don't work well ; i only use atmos with the speakers). Headphones sound quality is great though.
If you don't use camera that much (not my case) and you're okay with the speakers sound quality then custom roms are probably the best option out there.
@joaocandeias
I was fully aware of the camera issues I might encounter, this has been the case with my old Mediatek devices when going to custom as well, same camera issues, but at least...it works here. Yeah, I lost some functionality, but to me it's a good trade-off. It can still take snaps and film properly so it's enough for me.
I am kind of going to miss Dolby on speakers (never liked it on headphones though), as it did a really good job for podcast style videos on YT, but it still sounds way better than a lot of phones without it so it's fine. I just need to crank the volume up a little more than usual.
I've heard that treble Pie Roms require a oreo bootloader, is this true? I am still confused how to install on my A2017G. In which order would I install bootloader and vendor partition?
Hello,
Here is my problem.
2 days ago, I wanted to root my phone to get rid of any Google stuff (at this point I didn't know the existence of ADB commands :crying: ).
I followed a step by step youtube tutorial (youtube.com/watch?v=ZD-5twDm6XI), which works with TWRP, magisk and Odin (factory reset is needed).
Once everything is finished, my phone is finally rooted, and I grant superuser rights to Titanium app to uninstall google, and only SOME apps uninstalled totally (maps, chrome, facebook) BUT google play services won't uninstall. So, I try with System App Removal to uninstall google play stuff, and the same happens.
I reboot my phone, and it seems that everything disappeared... Not so sure... Indeed, the play store reinstall all applications as soon as I connect to the WiFi! and I have a persistent message "google play services stopped" that prevents me from browsing for example.
At this point, I use ADB commands, to remove anything which contains "com.blahblah.google.blahblah" and the play store (com.android.vending) with -k command. And it worked totally fine !!!!! I disconnect my phone, ready to backup my data. Idkw, i wanted to uninstall system app removal. IMPOSSIBLE from the phone, which says : "samsung One UI stopped" (I was in safe boot mode). My phone doesn't answer, so I reboot it.
Once it has booted, the TWRP menu screen appears. Ok, isn't that weird ? I swipe to allow changes, then I go to system to boot "normally" my phone.
A warning says : NO OS INSTALLED !!!! I don't understand, I panic, but finally boots my phone. Black charging screen. Forever.
I started first to flash an "official" Samsung ROM from Sammobile. TWRP indicates it is an invalid .zip, adb too. Odin doesn't manage to boot from the ROM too. I take a deep breathe and cry. Then I download the /e/ ROM which works fine !! but it has become impossible to backup my data from my samsung account....
So, I came to ask you a few things. WHY did it happen ? How can I be sure that there is no trace of TWRP anymore ? However, my phone storage is 64 GB and there is only 53,5 Gb free of internal storage !? Do you think the original firmware could be "hidden" in my files (e ROM is about 800Mos compressed) ?
It is stupid, but after my mistakes, I miss google...
I will do my best to reply asap.
Thank you for your help !
PS: -I'm a newbie in informatic, don't make things too complicated
-sorry for bad English, not my mother language
Google writes and distributes android.
There are many things in android that you cannot remove and still have a viable system.
imho you will have to flash a rom but we need your phones information (found in settings/system/about phone) model, version baseband, etc. etc
Others more knowledgeable can step in and help.

Thank you for your reply ! I've read your article about FRP but I'm afraid it's not my problem...
Here are some of my phone specifications :
model : SM-G950F
version baseband : G950FXXS8DTC1
OS : /e/ version 0.9-p-dev-dreamlte (LineageOS API : Ilama 9)
Android 9
I've been digging the web for ROMs but each time I feel unsecure about it (virus, etc...) so I hope maybe you have something trustworthy

So :
/system is occupied with 2.33 GB
/vendor with 577 MB
/mnt with 9.01 GB

If anyone could check on his device (S8 Exynos with android 9.0 Pie and One UI) if the files' sizes approximately matched, it would be great !
The one I just received is G950FXXS8DTC6 / G950FOXM8DTC1 / G950FXXS8DTC1 (after it took the Apr 1 update) so probably identical - a Yateley GU46 6GG UK phone. I am running it on ATT Prepaid(US) , which gave me the Apr 1 update. I don't know its history but it hasn't been modified - knox=0.
What you would need to do is get that zip and flash it with odin, but having no experience flashing the S8 myself, or any idea where to get that zip, I can be of no help to you. (I just came off a moto x4 which I ruined by flashing a couple custom rom's to try to help others on that forum - the blessings of Pie on that device!)(plus, taking the Apr 1 update on that phone requires a factory reset/wipe.) I needed a dependable phone here and in Europe on vacation.
Keep posting and ask someone to help you re-flash it.
EDIT: I wonder what a settings/general management/factory reset would do. But don't do one until someone here much more experienced with the S8 suggests it.
EDIT: WARNING WARNING WARNING -> Before flashing, ACTIVATE PIN in "Secure startup" (You'll be asked for it AFTER flashing!)
lockscreen and security / secure startup / require pin
I also see a note to delete your google account before doing this. Don't know if necessary.
EDIT: I believe I have found the rom - see pic This is from the SamFirm exe. 0.3.7 I put VOD for the region.
Remember: don't do anything with this until someone experienced in S8 tells you to!
Hi KrisM22,
I've already flashed with Odin, and I have talked about this on different forums, seen tutos on websites,... I hope this time it will work
I have the ROM required, selected activate pin, followed step by step the recommendations, and if I figured it out I will keep you up to date !

I flashed a ROM from https://www.imei.info/download-firmware/samsung/samsung-g950f-galaxy-s8/SM-G950F/ , then I just followed the steps and flashed with Odin. TWRP has disappeared (the classic recovery menu came back). I think I have found my issue with the "no OS installed" bug : it could be because I deleted the essential API com.google.android.packageinstaller, what may have prevented the phone from booting and launching the OS and its apps .
I should have read this excellent post before...
*I ran antivirus analysis with virustotal and Bitdefender, which both declared the extracted files were safe : I didn't notice anything different by my phone compared to the original OS too, so...
