Hi All,
Purchased what was advertised as a G8X unlocked for ATT, turns out its Sprint, and is Google FRP locked to a previous user. I try to do a factory reset and it says cannot unmount system partition at /mnt/system and say can't open /cache/recovery/log: Permission denied.
The phone is physically super clean, seems unused even. Any way to get past the Google FRP lock, or use any of the choices from the Android Recovery menu to update from SD card, for instance. I'm going to use it on a MVNO, such as Mint or Red Pcoket or H2O or something, so I have some flexibility there. I just don';t want to have to do a return if there is an easy way to get it to either load a new ROM or whatever.
I've used ADB some years ago , but would need to read a full guide, as I don't remember anything. I run linux on my PC's at home, have for years, so the file system seems familiar, etc.
Let me know if there is a super easy way to 1. Remove Google FRP lock or 2. Load a new ROM /Root this thing to get past the FRP lock and be able to use this phone without sending it back.
Thanks in advance.
You can try using the FireHose hack in order to unlock the bootloader, flash TWRP, and replace the various partitions with clean ones. Not sure how effective this would be, but give it a try.

Hi! I have an (annoying) situation here, i recently bought a phone (bottom), the phone has been wiped of all apps, however, the last person (the seller) didn't do a FULL factory reset, so his Google account is still the primary.
I know you can remove the primary account via factory reset, but there seems to some sort of PIN/password, you dont need a pin/password to unlock the phone (from sleep), the screen asking for a pin also popes up when i tried to apply a lockscreen password
Ive emailed the seller already, but he takes a long time to respond, and i hate to wait.
i know theres specialized hardware like Riff-Box, but this phones waterproof and i dont want to break any seals
Ive also tried to do a root, but kentai/japanese phones have tight security with a small amount of hackers (link to root bellow)
Anyway, my question is that is there anyway to get that pin out of the phone/disable/remove it WITHOUT rooting or cracking the case open
eg software hacks
ive already tried the ADB methods, which require a root, and i have a copy of SDK with proper ADB drivers if anyone has any complex suggestions
Phone
-Sharp SH-06D [normal, NOT the NERV edition]
-internationally unlocked by DoCoMo
-running an unrooted 2.3.5 and (obviously) stock ROM

Hi.
Before my question I'll write about my experience because I am sure it will help many many people.
As many of you, I always ROOT my smartphones.
Nowadays, the new phones, they come with this new technology to avoid root and other things called " OEM Lock " under the Developer's Options.
Following every step provided in the root guide for you phone, the new step to enable OEM Unlock under Developer Options
is a must!
The only thing that they don't say is that you MUST leave OEM Unlock ALWAYS ENABLED during and AFTER the root, and not only during the root
process.
Not knowing that, what did I do? Right After rooting my Samsung Note 5 I disabled the OEM Unlock. When I restarted the smartphone, it got into something called FAP Protection Black Screen where you are not able to leave not even if you try to root the phone again with the img file!
If you get in the FAP Protection Screen, like I did, despair will take over, I promise! And Google will not help you!
Is there a solution?
I found one, but not in any Google Page.
You need to download the firware img file for your phone, exactly same model,
in my case it was SM-N920G (Samsung Note 5), and for your specific country. Luckily for my phone it was not so hard to find, just hard to download (1,7GB with average 15 kB/s speed!). You will find different versions, some related to a Phone Company Operator that your country has, other related to no operator at all (sure I chose that).
After you get the firware file, just use Odin with that file to flash the phone, just like how you did to root the phone, but now, instead of using the root img file with Odin Software, you'll use the firmware file. That will not only solve the problem and give you access to your phone again, but in my case the Operator Flag disappeared and the data and apps installed miraculously were intact! I was pretty sure I was supposed to lose everything, but that didn't happen!
I'm sure what I wrote above will help many desperate people out there!
Now, my main question here:
You can never disable OEM Unlock in your life, with a rooted phone, period! So, it's really dangerous to leave the developer options enabled, allowing anyone that uses the phone to change it, even if by accident. In my case, as another example, besides rooting my phone, I rooted my father's phone too (because it was previously mine). I'd like to avoid by any means that by any chance me, or my father, disable to the OEM Unlock.
So, my question:
If I disable the Developer Option in order to "hide" it, will the changes that I did inside it remain working perfectly? I'm afraid that if I disable the developer options, somehow, it might take every option inside it back to the "default", just like it was before I enabled the developer Options, meaning in this case, OEM Unlock would get DISABLED again!
Is it safe to disable the Developer Options when OEM Unlock is Enable and MUST Remain like that?
Thank you.
Lost a night of sleep for the same problem with a Samsung S8.
This should be added to *every* mod guide.
In my case was worse too...if you root the phone and wipe data, when you open first time developer option you'll find "OEM Unlock" disabled (but I assume it's enabled at bootloader level). So when I check / uncheck it I doom my phone to lock on next restart...
how to get to boot menu on htc u12 plus, smallest width setting got adjusted wrong in developer options and power got cycled, all I can see on lock screen are 1,2 and 3 cant unlock, any ideas?
This is a problem, and it's doing my nut. I have a Vodafone Smart Mini 7, which I desperately want to root, to get all of Google's bloatware and the stuff the original network provider put on it.
I've already unlocked it to all networks, but the bootloader is being a PITA. I've done the usual with adb and fastboot, namely put it into USB Debugging, and then done this;
Code:
adb devices
adb reboot bootloader
fastboot getvar all
When I get to the section on the bootloader, it advises me that it's Secure.
I tried to use
Code:
fastboot oem unlock
and when I confirm on the phone that I want to unlock it, I get told that Remote Unlock is not allowed.
I assume that the fact that fastboot getvar all says that the bootloader is secure, means I need some sort of key to get it off. My old network provider don't know where to get it from, my tech team don't know where to get it from and I'm screwed.
Anyone got any ideas on whether I can get round the "secure" part of this, like some way of finding the key for it? Thanks

I have the exact same issue I read some threads and nothing solid has come out of it some say they managed to get root but others say they bricked the phone
Any news on this topic? I too have one i desperately would like to root because it is permanently full and you cant do anything wih it. The Google apps and the apps installed by my service provider take up all the onboard storage space. I downloaded only Whatsapp and Facebook Lite and bam,the phone is completely full and useless as it cant do updates,runs extremely slow and does all sorts of random stuff like restarting on its own etc. driving me utterly insane.

Hello! So I am on a journey to attempt to root a Samsung tab a7 lite sm-t227u. So I want to be extremely transparent as to my reason for rooting:
I was given this tablet by my father whom got it from a previous job. When he left the job they never asked for it back, a long with a good bit of supplies he had that he got to keep.
So, I have this tablet, I can get into it as it doesn't have a passcode. I have wiped it by factory reset as well. However, it has IBM's MAAS360 installed and after factory reset AND a firmware flash using odin I still cannot get rid of this maas360 mdm. It is not Knox locked. I can activate developer mode and change all those settings, but I cannot download any apps through the app store at all or enable unknown source app install as those are under an IT block. I also do not have the OEM unlock option in dev options. I've tried the whole changing the date and connecting to wifi, with and without sim card but I cannot get this option to show, nor can I unlock the bootload through fastboot.
I have read that most of the new samsung phones do not have a bootloader unlock option, but from what I can tell that is specific to the snapdragon phones, and this tablet is running a mediatek chip.
Now, if I can remove mdm restrictions without rooting that's great, but I have a feeling that is the only way to properly flash this thing to completely remove the mdm.
I have tried the recovery tar that is posted in this forum but I cannot get it to flash, likely because I still don't have an unlocked bootloader
Have any of you all faced something similar or know of a solution? I may call the company the mdm is managed by and just see if they will remove it from their system, but I find it highly unlikely.
SM-T227U is an American model wich doesn't have the OEM unlocking option, you could unlock using unofficial ways but those are not pretty "stable".

Hey man! Still got your tab 7? I also have a SM-T227U and have oem unlocked! After doing the usual stuff, you will want to turn off automatically update in developer settings. After that, go to settings>General management>Date and time and select manual time and date, and set it for exactly 10 days before the day you attempt this. OEM unlock will appear in dev settings!!!
Then turn off device and while holding power up + power down, plug into PC. It will show the pre-download mode screen where it asks if you want to continue. Just follow the on screen instructions to unlock bootloader!
*note that the bootloader unlocking results in an unavoidable factory reset**

Sweet! I will absolutely try this when I get home this afternoon, will report back with results!
But just for clarity. Let's say I start with a freshly wiped tablet. Go through set up and connect to wifi, do I need to add a Google and Samsung account? Then in dev settings, enable USB debugging, also enable wifi debugging? Then change the date. Is there any step I am missing?

If it has Mediatek chipset then you can use SP flash tool to format the tablet firmware and reflash it.
I would strongly recommend you to backup the NV DATA and NVRAM files before you format the tablet.

You can follow this guide actually! ( https://forum.xda-developers.com/t/...220-t225-install-lsposed-magisk-mods.4406933/) it recommends just skipping the setup junk
I have found that many times, rooting methods work across different models of the same device unless there are some sort of major differences in chipsets or some sort of random change lol
The only thing that doesn't seem to work for our model is section V of the guide which is for the removal of the "bootloader is unlocked" screen at startup. so you will still need to press the power button on that screen to boot up. It's a tiny hassle, but otherwise no big deal in my personal opinion
Make sure to read all the way to the end of the root section (section 4) and especially remember step 7. I retried probably 4 times and even patched the entire AP file of the firmware for use in odin (doing this gives a second warning on Knox screen that it isn't samsung official fw then boots normally into the bootlogo screen) before realizing everything was going fine.. I recommend just using the patched Magisk boot.img first just because I find it unsightly
Just flash the boot.tar in the AP slot. Don't download any of the boot imgs from the guide because they are for the t220's and t225's. I'll link the one I made according to the guide below. It'll save you some time and you won't need to install zarchiver and Magick just to have it factory reset again lol. Just download the latest Magisk apk (26.1) from the official github (https://github.com/topjohnwu/Magisk/releases) and install it when you have completed the 2nd factory reset/the patched boot img install.
