Hello!
I had rooted my phone last week or so using the Motochopper script. I didn't (and don't) know much about rooting and I ended up accepting an OTA update a few days ago or so, losing my root. I ran Motochopper again, but I either get "Failure [Install_Failed_Already_Exists]" or just "Failure." I've tried uninstalling Superuser, but reinstalling it doesn't give me root back. I've tried to use this guide that the search linked me to:
http://forum.xda-developers.com/showthread.php?t=1985699
But it requires doing a fastboot. I've installed this program:
http://forum.xda-developers.com/showthread.php?t=2317790
And it seems to work, but I get nothing when I run "fastboot devices" while my phone is connected. I don't know how to boot my phone into fastboot mode - holding the volume down button while booting just puts me into Safe Mode, and not even a Google search seems to reveal how to do one for my phone.
Is there any way I can ever get root access back? Is a factory reset my only option? I apologize if this post/topic is incorrectly done, but I've tried searching high and low through the forums and even asked a question in the Newbie Q&A and have gotten nothing.
Bump. I guess my phone is pretty unpopular.
Bump again. Is there somewhere else where I could ask this question?
Anybody?
Well, whatever. I guess I'll do a factory reset then.
Upon looking it up, I see that doing a factory reset won't affect any issues with rooting because it won't mess with the system files. It seems I'll have to flash the original ROM, but I can't find how to do that for my phone.
Alright, got it. If anyone ever comes across this topic through a google search, follow the directions here:
http://www.lg-phones.org/how-to-flash-unbrick-lg-optimus-f6-back-to-stock.html
And then run Motochopper again after finishing the flash.
Thanks for all your help, guys!
O.M.G. Someone else has this phone! I tried to root for the first time, yesterday. No go. FN update. If I get the chance to try this, I'll be sure to post what happens. Thanks for making this thread.

Yeah, no problem. It seems that if you take the update, you can't root. You'll have to do the flashing thing I put in my last post and just consistently deny the new update. You can do stuff to make it not nag you to update, but the biggest thing is not to take it.
Remember to use Motochopper too.
About the F6 root:
Just now caught this thread.
I've had the F6 for about 2 weeks now. Just getting used to it.
Then the "i" updated came in OTA by itself (sort of)...the standard consumer methods of rooting the phone wouldn't work for me.
That's fine, too, because most of the standard methods use nefarious means of rooting the phone, and should probably be avoided anyway. Several (maybe not MotoChopper) are actually Chinese trojan-ware, which you really don't want.
Most use exploits to trick the phone, and it's ENTIRELY unnecessary.
Use saferoot. This script based routine requires ADB, and if you're in Windows THAT requires the USB drivers for the F6, but you'll want those drivers anyway. Google for downloading ADB by itself. I have ADB because I have the entire development system for Android (and in my case, I use Linux for that).
ADB, if you're not familiar, is the "Android Device Bridge" - software which allows developers to control the phone for development purposes. Using ADB, one can simply ask for root (well, it's more complicated, hence the scripts of saferoot) - but that's what it boils down to. It doesn't use security vulnerabilities to root the device - which LG and the service providers have recently closed anyway.
After the "i" update, saferoot provided a permanent (it seems, anyway) root access to my F6 in about 3 minutes.
The F6 is quite recent, and while it's considered a mid-level product, it's actually quite good. It's recent release date, however, is why you're not yet finding much popularity - it will take a while before sufficient F6's are sold to acquire a following. Give it a few months.
thank you! saferoot worked great! on Metopcs an hoping for a rom soon!
So I've come across a new problem.
I need to flash my phone because of a problem with the Google Play Store. I ran through the instructions on the site I posted - which worked before - but it then asked for the B2CApp to be updated, which I couldn't do through the program.
I then tried to follow the steps on http://forum.xda-developers.com/showthread.php?t=2085344, but when the phone update began, it hit an error:
20:15:21 : Model.dll load error. Please check model.dll was built Debug mode
20:15:21 : Model.dll must be build Release mode.
20:15:21 : Please check model.dll is correct.

I have absolutely no idea what the matter is, as I've been able to flash this phone repeatedly before. There's also sharing violations with pictures in C:\ProgramData\LGMOBILEAX\images during the process, but I'm so frustrated with this that I don't want to replicate it now. I can provide the information as necessary.
F6 does not support Fastboot
Time will tell if this phone will ever have an unlocked bootloader. In what little free time I've had to experiment with my Linux box, I've come to the conclusion that the F6 isn't capable of utilizing Fastboot.
There is a TON of information out there, but I will try to educate myself on using ADB/SDK tools to try and find a solution. The downside is the demands on my time can be formidable, so it'll be slow-going (and I'm not a fast reader). Hopefully the XDA community will come through for all of us so we can move forward (Many Thanks in advance for the superior intelligence of all the Devs here !).
For what it's worth, the F6 is a very nice phone in my opinion. Coming from a now 2-year old Samsung Admire, I find the available 1.2GB quite sufficient! The Admire had only 137MB! I also don't live on my phone, and don't need that many apps.

This thread is a continuation of some of the discussion that was from this thread: http://forum.xda-developers.com/showthread.php?t=2568427
While not at all high end tablets, it's always fun to see what can be squeezed out of them! As stated in the title, this thread will be regarding the following devices: Nobis NB07, Iview 774TPC, and DA-741QHD (which all appear to be the same hardware) rooting and ROMs. That should be pretty simple for now since, we currently have no ROMs and no proven root method. Some have reported success using the Kingoapp. If anyone is able to obtain root, we would like to ask that you make a copy of the firmware and upload it for those of us having trouble doing so. After doing so, we can modify it and hopefully get more our of the software.
You may also post information regarding tweaking the ROMs for these devices and other ways to make them more useful!
Warning: The following may have unforseen effects including breaking your tablet to the point of being unrepairable.
Option #1, Use KingoApp Some users have reported that this did not work for them, at least one user reported that it did.
Instructions per RawX:
For the drivers the easiest method is just using Top Notch Tablets How to install ADB drivers. That worked on the first one, the second one it didn't not entirely sure why, but you can send a email to support and ask them for development drivers for the nobis tablets and they will send the ADB drivers you need. After you have the drivers installed use kingo while the tablet is in usb debug mode BEFORE plugging it into your usb port and do not turn on usb transfer. the first time after it reboots kingo will report that it was not rooted, leave it plugged in and power off and back on and it should report the root worked. This method gives you SuperSU. Both times. I've done this were for clients of mine but its pretty straight forward.

The working drivers for me were: VID_1f3a_PID_efe8
Please consider trying this first and give us some feedback. A word of warning though, there has been some discussion on XDA in the past that this may be malware though I'm not sure this was ever confirmed.
Option #2, Flash firmware for an alternate device that can be rooted easily. Warning!!! Currently, there is no way to get back to stock (until someone who gets root with another method makes a copy of the firmware)
Go to this website: http://www.iviewus.com/firmware788TPC/ and download the firmware. Yes, it is for another tablet. However, the tablet appears to have the same specs as ours. Once downloaded. Install the included PhoenixSuit software. Once it is running, click the button at the bottom right to update the software to the newest version (this may not be required). Then, plug in your tablet using the usb port and install the drivers. I used google and found them all within minutes. Once the software recognizes your tablet go to the firmware tab where you have extracted the .img file and select the file. Next, click upgrade to upgrade your tablet (it has instructions to help your tablet be recognized if you are having difficulty). Once the new firmware has been flashed, then download the file RootFromOTA.zip that can be found on various places such as XDA. Move the file onto an external SD card. Then, go to settings -> backup & reset -> Recovery Mode. Your tablet will restart. Once it does, select the bottom option to install from SD card. Install the RootFromOTA.zip and then reboot. Once rebooted, install the supersu app or another root application of your choice.

Congrats... You're rooted.
Mods
Currently, I've managed to get great battery life out of my tablet by installing kernel tuner and changing the settings as such:
Governor: Ondemand (default is fantasys)
Max: 1200 MHz (Default is 1200 MHz)
Min: 240 MHz (Default is 120 MHz, but I had trouble with usability at this setting and Ondemand)
I also recommend setting wifi to turn off when the screen is off and turn off autosync.
This seemed to give me a very useable system but with greatly improved battery life. Doing the above and a few other tweaks here and there have made my battery life so that it drains by about 1% overnight when not in use. I also seem to get better battery life while using the tablet. I haven't had any trouble playing games either.

I am assuming the camera is not working using this method or did you figure it out?
And also, do you have a link to the drivers you used off hand or what did you search for to find them?

Nope, still haven't gotten the camera working. We are missing some config files still. Do you need the camera drivers or the tablet drivers?
The camera drivers are : sp2518 and sp0838, though I also see a module being loaded called cam_detect
I don't recall where I got the adb usb drivers for the tablet, but it would probably be a good thing to mention in this thread so if you have them, let me know and I can add it to one of the top posts. If you're having trouble finding them, I'll remove my drivers and go back through the process to find them again.
Looking for the tablet drivers. I am about ready to tap out on this thing for a while. lol Its driving me crazy.

OK. The drivers I used were probably: VID_1f3a_PID_efe8 (or something similar)
You can either google that or try downloading the firmware for TP718AQ here: http://www.agptek.com/forum/viewtopic.php?f=22&t=948
Remove all prior drivers for the tablet. Plug it in and tell Windows to use the drivers from the extracted file you download (Will extract to TP718AQ_Update_Firmware\USB Driver).
Sometimes I have to do a little dance with restarting the device and my computer to get it to recognize it.
As a last resort you could try this: http://www.xda-developers.com/andro...r-solves-your-adb-driver-problems-on-windows/
Let me know if you have any problems.
Good Luck!
Ok, I officially give up trying to root this thing. Stupid windows will not install the drivers in both the links you provided and I cant get windows to even try to install anything after removing them then I got the android ADB drivers to install but still zero luck. All rooting apps fail. Hopefully someone will post the image of their rooted NB07. A few claim to have rooted it just fine but I cant win with this thing.
All I want is to be able to run link2sd and a few other apps that require root. This is officially the longest I have owned an un-rooted android device. lol
I'm the one that got the root working using kingo, so for the drivers the easiest method is just using Top Notch Tablets How to install ADB drivers ( I would post a link but I don't have 10 posts yet on XDA)
That worked on the first one, the second one it didn't not entirely sure why, but you can send a email to support and ask them for development drivers for the nobis tablets and they will send the ADB drivers you need. After you have the drivers installed use kingo while the tablet is in usb debug mode BEFORE plugging it into your usb port and do not turn on usb transfer. the first time after it reboots kingo will report that it was not rooted, leave it plugged in and power off and back on and it should report the root worked. This method gives you SuperSU. Both times I've done this were for clients of mine but its pretty straight forward.
Well, I have decided that for now this tablet of mine is un-rootable. I must have tried with 5 or 6 different drivers about 20 times with each with Kingo. I even tried that other program that is all in Chinese that loads some BS app on to your phone with no luck. So, for now, I am going to give up but if anyone has any other ideas or wants me to try something or they have for sure figured out how to root it, let me know as I am happy to help the best I can.
Edit: Oh yeah, Dont know how much this will help anyone but here is some more specific specs on the Nobis NB07 tablet I pulled off it with Hardware Info 3.0.0. Feel free to put the link in the first or second post if you want. Maybe it will help a little bit more.

Thanks to the work of someone on another forum, I have now got TWRP working on our device and am hoping we will soon have a CM working on it as well. Check back in the near future for further details. Maybe if you can't have a rooted stock, we can get a fully functional CM.
I am assuming you need to have root to flash the TWRP recovery correct. This is good news. Would love to have more info on it. Are you working with people on this site or another site? I would love to follow along.

On another site for now. Just PM's at the moment so not much to follow yet. But, all you'll need is the Phoenixsuit to install it, so you won't have to root your tab first. You'll have root on the new ROM. You'll have to have drivers fully working though. Once fully working I'll link to the site so people can get the files and hopefully we can get this guy some donations for his work.
Awesome! I would go right to CM on this and skip the whole rooting the stock firmware. Would be nice to be able to root the stock firmware though then things would be so much easier. Think the camera will be working on the CM build? If not no big deal but would be nice to have them working.
Keep me (us) posted on the progress.

Not sure about the camera yet. I have CM booting but no touch yet, so this will be the first task. I'll keep everyone posted.
Any word on getting things to work yet?
Currently, we have CM working with no touch screen/camera. I'm not sure what else all isn't working because I'm waiting on my OTG cable to come in for further testing to see what all is going to be required to get the touchscreen going. Right now, it appears we my be looking at compiling our own drivers which could take some time to do. I think we'll get it eventually, but it may take some time. If you don't need touchscreen or camera, it could be working right now.
Sorry for no updates for a while. My work has been delayed on this since I have a son who is sick and in the pediatric ICU. I'll get back to work when things calm down for me.
No worries man. Family first.
Just a question, Hippie...
On the original ROM, can you see your device in ADB? If you can, and type "adb shell" do you get root? If you have adb access but not root, can you try typing sh and see what happens?
Also, could you try loading the rootfromOTA.zip and see if you can get a printout of the error log if possible?
Also, I tried installing this from the recovery on a similar ROM and it acted like it failed. I went back into the ROM and used adb and was able to get root using vroot or kingo...I don't remember which. This may be worth a shot.
Interestingly, I have been looking for alternative ways to root and found this (but we need to find a way to get to the bootloader):http://whiteboard.ping.se/Android/Rooting
I think that the method to get to bootloader is to turn off the tablet, then hold down the back button while tapping the power button 5 times. But, I also googled and found a method for getting to fastboot from adb in android without root as well which may work.
Hello people!
I haven't been to XDA for a while since my XPeria T has done a nice job for me, but lately it's starting to show how old it got, not because apps got newer or required more resources, but it started switching keyboard to Chinese without letting me switch back, I can't answer when my phone is ringing, blue screen flashes on YT app etc.
These are just some of the problems I encountered, but I won't bug you with the details as I gave Sony a nice amount of rage on their FB site for releasing damaged software to not-so-expensive phones and leaving them that way...
Before I had HTC WFS, and my friend rooted it for me, so I am still kinda new in this, and if anyone could briefly describe step by step process of installing custom ROM with root I would be very grateful.
The reason I'm asking this is because I'm afraid I'm gonna brick it if I do it on my own, I've done the easy part (downloading SDK and fastboot driver), now I have to install it, find a nice ROM I have, but I still need to install CWM and before I've had some problems (because of the firmware I think, when tried installing 4.4.4 on WFS it couldn't after 4.4.2).
Also, is there any way to back my original software up in case everything goes downhill I can just roll it back, continue complaining how I have a ****ty phone and be satisfied with it anyway?
So, just to be clear, my knowledge of Linux systems isn't great, at least not to experiment on my own (ironic as I'm programming in Python) so if anyone could make it look like this:
1. Do this
2. Do this (in case it fails, do this)
3. Then do this
Done!
I would be forever grateful!
Thanks maties! (sorry if the question is too simple, I've tried gathering information from "xperia t development" thread, but there's so many things and I don't understand what half of them do, I requested to unlock bootloader from Sony and I'll try to do this on my own )
EDIT: We're talking about GSM Xperia T (Croatia, Europe) in case anyone needs that info!
Okay, I think I've successfully unlocked the bootloader since I got this text in CMD after a long headache of installing fastboot drivers because win10 (as windows 8) has to have disabled option for preventing unsignatured driver installation or something.
So I got this text: ...
(bootloader) Unlock phone requested
OKAY [ 0.422s]
finished. total time: 0.422s
So now I'm going to try and install CWM from here: http://forum.xda-developers.com/showthread.php?t=2657190
Not because it's touch, but because it's the last version of CWM posted on Xperia T subforum so I'm hoping I'll be able to install those 4.4.4 ROMS
EDIT: It seems I need to root my phone before doing it, so I'll try to do that before I install CWM
Okay, now I'm stuck (thanks God it's not fatal)
As I'm trying to install CWM to my phone and it's not rooted, I first tried a method above, but .bat file gets stucked @ Daemon started successfully.
So, I decided to give flashtool a shot, installed all the drivers, when I connect the phone everything seems normal, then when I click on root (SuperUser and SuperSU) a little program appears on my XPeria and when I click "make it ra1n" the phone reboots.
Debugging enabled, unknown apps (or similar) enables, fake locations enabled.
Darn.
I'm out...spent whole day packing my old FW downloading other one etc. to find out it's the newer one, I didn't pay attention to number before last one...
If anyone could tell me which version is rootable, I'd be grateful, I don't want to give up yet...
EDIT: Never mind, found everything, I think puzzles are finally coming into places...
Hey everyone!
So, just upgraded from my Note Edge to a Stylo 3. I'm going through my usual ritual of boot, root, remove useless apps, Xprivacy, migrate data, move SIM card, a process that's getting progressively more annoying but I do want to thank everyone who makes the tools used to make this happen.
Anyway, I got to a point where I must've frozen an app I shouldn't have or something; ironically Jrummy's App Manager wouldn't work thereafter...nor would 'Messages' or a few others. I disabled Xprivacy, used Titanium Backup to defrost every app I'd frozen, disabled AFWall+...and still, things weren't happy. "Okay, let's just factory reset it and start over!", I said to myself. And, I did so. Now, one of the apps I froze was "EULA"...which is a requirement for the initial phone setup, thus preventing me from completing the initial setup wizard. "Okay then, let's just wipe and reload". I found the T-Mobile KDZ file from one of the dozen sites I've been to in my quest, and the LG Flash Tool. It wasn't until I tried using LGFT that I gained a true appreciation for Samsung's Odin, because the 2014 version doesn't seem to want to talk to my phone, giving me the "can't find server" error, and unlike the instructions I was following, the screen didn't indicate that the file was actually moving. The 2015 and 2016 versions of the tool both seem to want a DLL file, which is nowhere to be found.
Now, the saving grace is that I do still have access to TWRP, so if there's some variant of "chmod 777 -R" I can run on a directory somewhere to make sure EULA.apk and its friends are all defrosted, and that's possible from TWRP, then I'd super appreciate a tutorial on how to do that. Alternatively, if someone knows how to get LG Flash Tool to actually shuffle the bits out the USB port, I'm open to that as well.
Thanks for reading. I appreciate your consideration and assistance.

[SOLVED]
Yep! I managed to poke and prod a bit more, and solved my issue. For the other folks around these parts, the key is this:
https://forum.xda-developers.com/lg-g5/development/uppercut-lgup-loader-g5-variants-t3511295
I used Uppercut, as directed, in 'Upgrade' mode. I used the KDZ file downloaded from here:
https://lg-firmwares.com/lg-tp450tn-firmwares/
I opted for TP45010c_00_0821.kdz, because I didn't want to run the risk of upgrading the bootloader and preventing myself from rooting.
Once I used Uppercut, it wiped everything, and I was able to restart the process again.
I hope it helps someone!

First thing always when you get a custom recovery is to make a backup right away that way if things get messy you can recover, most phones and even this phone a guy has a flashable zip for TWRP, Uppercut works too but it's very easy to mess things up and you think it's not working because you did something wrong but as the guy above mentioned uppercut is what you will use, if that does not work for what ever reason then you have something else going on, driver's or something. If you can boot into the phone at all, then plug it in and tell it to reboot to bootloader that way you can flash it using uppercut, if you have access to twrp you can try that zip file
Hello Guys,
i had bought an Huawei P20 about an year ago. Now you know with all of this "USA-Huawei" Trouble going on, the thought came to my mind that i better start unlocking bootloader and be prepared to flash custom rom if worst come to worst. so far, so good.
now i started looking around if there is an easy method of getting the bootloader unlocked. but oh my, the huawei company is very friendly to us users and say "no, you wont get any unlock code from us anymore". so screw that.
now i want to try some experimental stuff. it looks like this:
my Smartphone has currently the version EML-L29 8.1.0.168(C432). I bought some Credits (i think it is that thing for $4) from DC-Unlocker. Yeah yeah i know, there they say "no support for Huawei P20!!!". But i still want to try. Well i tried, but it doesnt work - what you should expect.
now i read from some other website that there is another way of unlocking it. i only read it diagonal but the one thing i read was the information "unlocking bootloader is only possible till firmware version june 2018". so i jumped to an maaybe interesting conclusion about unlocking the phone with DC-Unlocker or HCU (whatever, i guess maybe both use the same method anyway).
if i do an rollback to the old firmware version *before* June 2018 on the device, wouldnt it be possible to do the unlock? Because the security patches that preventing it unlocked arent on the device then.
So what i have done so far is loading the old firmware version 8.1.0.128(C432). But the source is saying that it is coming from "Asia" but in the next line it reads "Asia, Europe" etc. - do they mean that this version is universal or do i run in trouble if i install one that is having the wrong area?
the next thing that kinda baffles me... all guides are sayin "copy the extracted dload folder to your sd-card". even the p20 guides do that. but.. well you know, the p20 device doesnt even have sd-card support. so how are you intended to use it then? i wonder about that a bit.
i dont think that without unlocked bootloader, flashing an original OTA full update would be impossible. but im not really sure how. there is this shady menu you can reach if you call this strange numbercode. but im very unsure if that will really work out. the phone (it is still a phone without SD-Card-Support) even has the option "apply update from sd-card". so im wondering how this feature they implemented in the original software is intended to use at all. maybe i should push the dload folder on the internal storage? i dunno.
i read about another possibilty of flashing stock roms. they say you can do it per adb command. so no problems would be here, i have adb and the hisuite and all already set. but i have absolutely no idea if that is possible without unlocked bootloader. so the questions arose from my mind are those:
- does an stock rom image from possibly/maybe asia would do any harm to my device like it is getting unbootable or anything like that?
- is it possible to flash an image older android stock rom with methods like this special menu on the device or the adb load?
- do you all think that my plan of downgrading the phone in order to get the bootloader code would work?
i'm looking very forward to your answers )

No. Sorry. There's no solution. Reason: It would appear in this forum within minutes and thousands of people would be happy to unlock their bootloaders. Many Huawei-Owners here on XDA invested a lot of brain power to find a way. Noone succeeded. No bootloader code, no unlock.
If you still want to play around with firmwares, please inform us about any progress.

okay so there are basically no real information. look, i dont expect anyone to say like "oh there is an easy method xy" because i know it doesnt exist on this moment in time.
however i made an percent of an progress, it is more a thing for other interested custom rom modders out there.
i downloaded this update.zip and there are all kinds of howtos on the internet about it. the one thing i did is basically create the dload folder. then i put the extracted update.app in there. i rebooted the phone with power, vol down + vol up. i released the power button after the vibrating. the flashing screen indeed appeared! but something very strange has happened and i have no explanation what have happend.
so the emui updater appeared. there was this emui logo in the middle, the circle building up around it. but then it stopped at 5%. i really got panicked that im about to brick my device. so in an mad attempt i wanted to stop the update and power off the phone. glad i didnt do it. the phone always said if i tried to press the power button long enough "the system will crash if it is powered down". i stopped - but i tried it serveral times to stop.
now the strange thing is.. it stuck relatively long on this screen. but after a while (i guess it was 5-6 minutes) it suddenly got dark. and the battery was at 100%, so it wasnt a faulty battery. i just wondered. the phone - other than i would expect - rebooted. after a short while of the logo flashing (for about an half minute) it finally started. first i didnt have any connect to GSM Network. but after a short while that was okay too. all apps are still there. i looked at "about" and the version is still the same as before.
do someone have any imagination what has happened there? so apparently the phone *does* try to install something on this method, but the method seemed to fail. or is there any knowledge out yet for update logs that are getting generated by this process? i try to find any hint in order to tackle this problem atm.
and one thing is still on my mind.. could it be that the update is already through and i just didnt realized it yet because these other custom files werent changed? i mean that could be an possibility to say the least. anyway, i will try to use hcu now if maybe sth has changed. and i give kingoroot as well a shot if this buddy finds everything about rooting the device. maybe with root rights through exploit i can get further.

It seems you have a couple of questions, pal, I answered to the first one (Bootloader Unlocking through Downgrade possible?). All I said is that it's impossible to unlock the bootloader through a downgrade. If you read all the how-to's you should have noticed that FirmwareFinder doesn'st work anymore since EMUI 9.0. This Information simply means Huawei doesn't allow us to flash updates on our own anymore like we did before. For sure there are some guides how to rollback to Android 8 but even this changes nothing to the bootloader.
Sadly I have no answer to the other questions about the strange behavior, it sounds pretty odd. Never heared something like this. But good luck fixing your phone anyway.
well i found out a couple of things now.
first thing: you know the service menu when you try to apply a zip archive from sd card? well you wont be able to use it UNTIL you use an usb-otg cable and an exFat formatted USB-Stick. Next thing to know is, you have to use the right images. there seem to be an kind of rule how this images are supposed to be and the image i found was from an russian firmware download site it was linked here in the forum in a thread. so i did choose "apply zip from sdcard" and .. IT DOES! the device rebooted, the stick flashed and the flashing process occured! and guys, im back to Version EML-L29 8.1.0.128(C432)! it is clearly stated in the build version view in settings. so.. i guess you *can* roll back even without firmware updater.
so far so good. but lets get back to the problem with the Bootloader. sadly Jan Philipp was totally right.. the bootloader cant be unlocked even in this version with the security patch of 5. may 2018. that is kinda sad. even kingoroot is still no different from before. i guess i have to search now for an way to get the system rooted. however, it must be easier on an earlier security update stage like now instead of the future versions of emui 8.1.
edit: another strange thing i discovered so far is that after this restore.. the play store wasnt able to connect to the google server until i gave permission to a few google processes to calendar and file access (i wonder what that is all about). maybe it has something to do with incompatibilities in the rom versions but now it works just fine as it should).
"unlocking bootloader with exploit is only possible till firmware version june/july 2018" does not apply to 2018's devices with kirin970, kirin980 & kirin710.
You are with kirin970.
So to unlock your kirin970, the only way for now is to wait for 3rd party seller to hypotheticaly start back their dervice:
- In the last 6 months there was only 2 'windows' which lasted 3 or 4 days where you could order your bootloader's unlock code by imei (from 5 to 124 us$).

Google Play services require all permissions, otherwise won't work.
I also been searching on how to unlock the bootloader and found no solution or hope. I guess we are stuck with EMUI forever.
Reply from Huawei:
You can roll back to earlier versions of EMUI software, but you have to roll back one version at a time. However, our earlier phones operate exclusively on Google Mobile Services so removing it would limit the functionality extremely, however, we do have a range of new devices that no longer rely on Google Mobile Services and use Huawei Mobile Services instead - such as our P40 series.
Here are the instructions for rolling back software:
[Rollback Guideline] EMUI 9.1 (Android 9) Rollback to EMUI 9.0 (Android 9) Operation Instruction
EMUI 9.1 (Android 9) can now be rolled back to the official version of EMUI 9.0 (Android 9) using HiSuite, without downloading any intermediate packages. To ensure that the rollback succeeds, read the instructions carefully and perform the steps as instructed.
1. The following are precautions for roll-back.
a. Rolling back to an earlier version will erase all data on your device. Use an SD card, computer, or Cloud storage to back up all important data before rolling back your phone, and make sure all backed up content is complete and effective.
b. Use a computer running a Windows operating system to visit http://consumer.huawei.com/minisite/HiSuite_en/index.html and download the latest version of HiSuite. If HiSuite is installed on your computer, click the version number in the lower left corner of the page to check if it is the latest version. Make sure HiSuite version is 9.1.0.303 _OVE or above.
c. Before rolling back the phone, make sure your phone has not been upgraded using non-official updates. Otherwise, the roll-back may fail and unknown issues may be introduced. If you have used non-official packages to upgrade your phone, it is recommended that you go to an after-sales service center to roll back your phone.
d. Before rolling back your phone, make sure that your phone system has not been unlocked or rooted. If the system has been unlocked or rooted, it is recommended that you go to an after-sales service center to roll back your phone.
e. Before the roll-back, restore the phone to factory settings to make sure there is enough storage space.
f. Make sure the battery level is more than 50%.
Hi All,
I need assistance to update my EML L29 Huawei P20 phone.
The phone is Locked and FRP Lock
Issue the phone is always booting into recovery mode and not into the main screen.
I tired flashing via CMD using twrp.img file but its not writing.
Need help
Hi Everyone,
Living in Japan, we have no official channel to purchase a OnePlus handset here.
Really wanted to get a OnePlus 7 Pro as I felt it is the best model on the market as of today.
Knowing that, I got mine on Amazon Japan from a HK online shop which had very good reputation.
Now, the problem is these phones always come already opened as they say they need to confirm operation before sending it.
I have been reading news and article about this where we see more third party companies flash their roms with malware/ransomeware already built in...
In these situation, the best way to clean the phone is to do a full re-install of the OS.
I did review a bunch of article on XDA and it seems that now, due to the A/B partition setup, we can't just use official OnePlus image to load from the fastboot easily.
We have to rely on community provided too and stock rom to be able to do so....
When I raised the question to OnePlus and Oneplus forums, they mentioned to me that installed the updated like here (Page: support.oneplus.com/app/answers/detail/a_id/4312/~/oxygen-os-for-oneplus-7-pro)would do the trick using the local update function.
What I was directed to do is use the recovery boot to delete system settings/cache and everything data user and then, run the local update. Doing so, that would do it while not using community tools.
Here are my questions and which I would hope to get your experience:
1 Is the process I did really does use a brand new clean OS and do not rely/integrate part of the OS that came with the handset originally (that was the target).
2 Is there a way for me using OnePlus only provided tools and image to fully delete the phone and install the OS (maybe I am thinking this too much like a PC which I have more experience with...)
3 The OS looks fine and no strange apps shows up at all but how can I be sure nothing dodgy is running? Is there tools I could use to confirm this?
Sorry if I sound paranoid. Ideally, I understand the best thing to do was to buy directly from Oneplus and work a way to have it shipped to Japan but thought it would be interesting for me to learn more about android.
With previous Oneplus, it was easier as they were provided this type of official file for recovery but they stopped...
Thank you again for your time and hopping to learn more about how new android setup works.
Is the bootloader locked? Is Widevine (Netflix HD) certification still there? You can check these things to see if the phone has been tampered with.

Good questions. Before you start, check the model number of your device through Settings > About. I'm assuming it's the international/global/unlocked version (GM1917).
With regard to question 1, a full build downloaded from the link you provided should contain every part of the OS, and flashing it through local update should overwrite anything that was there before. Before flashing, I would perform a full data wipe through recovery like you mentioned.
Q2: There is an MSM tool that will completely flash a system image for the OP7 Pro. I don't think they're generally intended for public use but they always get leaked anyways. They write an image (in the case of OnePlus, a .ops file) to the phone using a PC and USB connection. Here is a link to a thread which contains the MSM tool:
https://forum.xda-developers.com/oneplus-7-pro/how-to/guide-mega-unbrick-guide-hard-bricked-t3934659
Download the tool for the model of your phone (probably the international, firmware GM21AA), and extract its contents into a directory. In order for the tool to work, you need the OnePlus USB drivers installed on your PC. Plug the phone into your PC with it on, and enable USB file transfer. Open File Explorer and you should see a drive labeled "OnePlus drivers" or similar. Open it and run the driver setup executable file. You'll also need ADB to make your phone reboot into a mode that will allow the tool to perform its tasks. Here is a guide to installing ADB:
https://www.xda-developers.com/what-is-adb/
Once you've set that up, make sure the phone is plugged into the PC and the MSM tool is open. Make the phone boot into edl mode by typing
Code:
adb reboot edl
and once it says Connected next to a COM port in the tool, press start. Don't interrupt the process until it completes the download and the status message turns green. The phone should automatically reboot. This method is arguably more risky than using the local upgrade option, so do it at your own risk.
Q3: Make sure that OEM unlocking is turned off in developer settings and that the bootloader is locked (if the bootloader is unlocked, you'll see a yellow warning message after you power on the device from a power off state). Without an unlocked bootloader it would be pretty difficult to make any deep modifications to the device.
Hi @Zocker1304 and @TManchu,
Please let me thank you very much first for your kind and detailed reply, this is really welcome.
@Zocker1304:
I checked using the ADB/Fastboot connection that indeed, the Bootloader is locked so, that looks good.
Also installed (using a separate Google account) DRM Info app to confirm that the Widevine is properly installed and at L1 level which indeed again, looks good.
@TManchu
Thank you again for your very detailed reply! This was exactly what I needed as information.
I did already exactly as mentioned for the #1 so, it looks I should be good now with a proper rom from OnePlus (and did a full wipe in the Recovery boot mode)
For #2, I think I will skip that since as you rightly said, with #1, it should be fine so, prefer to keep with the recommended step.
For #3, we are covering what Zocker1304 mentioned too and I could confirm it.
My only concern about #3 was that you can actually relock the bootloader but (and please correct me If I am wrong), you can only do so if you are using stock OnePlus images (to date...seems like dev teams are working to have this changed? Bootloader locked with custom firmware?) which then means the image is safe.
I suppose the last item was my only open query for your thoughts but so far, the handset looks fine.
Thanks to you and the community, I have learned about the A/B partition scheme, msm tool, Fastboot/Recovery mode and Bootloader and ADB tools.
It is always good to learn more about the tech we use (especially phones, we have so many sensitive information stored into them today).
Not being careful could potentially means quite a lot of troubles down the road with Ransomeware/data leak tools.
Of course again, I could have simply purchased a JP phone from a brick and mortar shop next to my place and be fine with it. :silly:

No problem! I’ve just done some reading and from what I understand, re-locking the bootloader on anything other than a completely stock ROM will result in a bricked phone. I believe this is due to the way Android handles data encryption. If what you’ve heard is true, being able to lock your bootloader on a custom ROM would be great for device security. However, should something go wrong with the ROM having a locked bootloader might make it more difficult to fix.
I know that there are ways to sign system and boot images so that you can lock the bootloader with them installed, but I think that would still show a warning though I'm not sure.
Anyways, if all the build dates and numbers in the system info are correct, the firmware should be stock and as long as the bootloader is locked too, I don't believe you can tamper with that.
Hi Gents,
Thank you very much for the answer to the thread and much appreciated.
Apologies for not getting back to you all earlier as yesterday was family day...haha!
Well, since things looked good on the OS and the build, I went ahead and started to use the phone properly setting up my accounts. It did give me some incentive to get all my sensitive accounts setup with 2FA so that in case I get hacked with my passwords in the future...they would still need the 2fa (using Google Authenticator).
I did check also all system apps/running process and didn't see anything shady.
Just for reference, here were the type of articles I was refering too for the OS being plagued with malware even out of the box:
Page_theverge.com/2019/6/6/18655755/google-android-malware-triada-ota-rom-ads-spam-oem (sorry gents, new account, cannot put links yet)
However here, it seems it is due to lax review from the maker to third party tools which were including malware...
To have the same level on the oneplus I bought from the HK shop, they would have needed access to OnePlus Dev team to inject the malware in official image (knowing anyway I have re-installed a new image from the local update).
Otherwise, I was reading on the web about the fact to relock the bootloader with a custom roam and there seems to have a lot of messages but not concrete steps. It seems it depends a lot on phone model and brand.
When you are checking
Page_gizmochina.com/2019/06/10/relock-bootloader-oneplus-7-pro/
This is where you can read at the end:
"The above method only works if OnePlus 7 Pro is running on stock recovery and stock firmware. The ability to relock devices running custom recovery is expected in the next few weeks. "
That was published last month so, not sure if they got this to work on the OnePlus 7 pro yet.
So that's it, I am now using my new device which looks to work great and hopefully, won't get any bugs down the road.
I appreciate you taking the time to get back to me and will continue to learn about android.:good:
