I have a old business phone (J3 J330F/DS) that I want to use for my child but when I power up the mobile launch a Knox app that I can't skip (ask me for a corporative password).
I can't give the phone to the IT department because I work in other company today (The company never requested me the device).
I am trying flash a new rom but I can't set the mobile un download mode. I tried all combinations that I found by Google (power+vol down+home, power+vol up+vol down, etc, etc, etc).
I think device have some type of modification in the boot process that doesn't let me enter in this mode (I got enter in factory recovery mode but there are not a 'reboot in download mode' option).
Somebody know some alternative??? Thanks!!!!

No alternative is known.
Only the IT administrator of your previous employer can unlock the phone.

Hello, i've got a similar problem before... The only solution i found was to flash a stock rom for my device. I hope someone know a solution, less "radical".

you can try to boot into recovery (hold vol + (or -) then press power button) (or use the mobile uncle app)
select there "format to factory settings" or "wipe storage" or something .

Hi Everyone,
I bought the Honor View 10 and it was delivered to me on 16.08.18. On 17.08.18 all of a sudden while using the phone, the screen went black. The phone is working though as I called from another number and it was ringing. The screen lights up but it is completely black. Since the seller has a replacement policy, I have already raised a complaint and the phone will be replaced. The issue I have is, all my data is on the phone and I am unable to wipe it. I can't do it via adb as it needs to have the USB debugging option enabled on the phone, which I can't enable now. One method I tried was tying to boot into recovery and assuming that I am pressing the correct buttons and wipe it from there. But this is very hard and I am not sure if I achieved anything or not.
This is what I did:-
1. Since the phone is on and currently stuck on lock screen, I need to enter the pin which I can't. So, I keep on pressing the power button until it reboots.
2. Then I press the volume up button and here I think I am booting into recovery. I think I was in recovery because my phone was connected to my pc and it stopped recognizing it. After this I did some button pressings and not sure if anything happened.
If anyone has a method which I can use to wipe my phone, please share. Thanks in advance.

Thanks for the link. I tried it, but since the location on the device was turned off, it is unable to connect to the phone. Here is what more I tried so far:-
I was able to boot into fastboot mode. But none of the commands worked. "fastboot -w", " fastboot erase userdata", "fastboot reboot recovery". My pc is reading the device because when I type " fastboot devices", my device is listed. And the other command that is working is "fastboot reboot".

Another thing you can try, if WiFi is ON on your device, is try to install app to mirror the screen of the phone to your PC, you can do this via PC, open Chrome, log in with same phone's user, get in Play Store and install the app
Sorry but right now I don't remember a good one, but if you search, sure you'll find a good one
turn on internet
login to your google account
go to find my phone option
there you will have option to erase your data

Yes location is off on my phone .. I tried that option though but couldn't locate the erase option there .. these were the options:-
1. Ring or Locate
2. Check recent security events for suspicious activity
3. Try calling your phone
4. Sign out on your phone
5. Reach out to your carrier
6. Learn how to take extra steps next time
I tried searching for a mirror app as well. But all the apps I found needed to be opened once on the phone. So, got stuck in that step.
The new replacement phone was ordered today and it might get delivered by Friday. I think I'll visit the service center once before the new phone arrives and this one gets picked up. I though don't think they'll be to erase my phone without replacing the screen. But still I'll give it a shot. Apart from that, if the batter dies and the phone turns off, I'll then try to boot into recovery and wipe from there. Do you know any button combinations which can be used to turn off the phone?

Hi all,
I need your help.
I've got in my hands a P30 (of a friend) that got stuck at boot last week. According to him the device just switched off and would refuse to boot correctly afterwards. Now the device has no physical damage and he could get the main board replaced under warranty but he has a lot of unsaved pictures on the device that he really wants to recover (even if that means voiding the warranty).
When powering on the device, first i get the "The device has loaded a different operating system" screen, followed by the "ERROR MODE" screen with :
Func NO : 13 (recovery image)
Error NO : 2 (boot failed in recoveryboot mode)
I can neither get into recovery nor e-recovery mode; all attempts end up at the ERROR MODE page.
The ONLY thing I was able to get working is fastboot mode. I this mode I go get fastboot to work from a PC and access the device. Hi-Suite however does not "find" the device.
Now as the device is not OEM unlocked, i presume that there is not much I can do in fastboot, right?
My friend would even be willing to send the device to a specialised lab (if that exists, for now I couldn't find any) but I am not sure if that would help anyway; I presume that the userdata partition is encrypted.
Any help / suggestions would be highly appreciated, again the main target being to recover the pics and videos from the device.
Thanks a lot.

Hi m8,
First of all, check for an recovery firmware through eRecovery. In order to do that, check my SS bellow (available on EMUI 9.1). Do as it says and let it download + install (if it's entering).
Second, if he has loaded EMUI 10, in order to enter eRecovery, Power OFF your device or Restart it. Then press simultaneously POWER+VOLUME UP and keep them pressed untill you see Huawei on screen. Release the POWER button and keep pressing VOLUME UP untill you are in eRecovery menu, then release button. When in menu, select Update mode, then select eRecovery mode then Update and recover system then Download update and recover. Connect it to Wi-Fi and it should start the update. At the end, it will restart to system.
Report back your result so i might help you if none of these 2 are working

Hi SilviuO,
thanks for your reply.
Unfortunately, as mentioned in my initial message I don't have access to eRecovery.

When I try to boot into eRecovery I do get the first screen asking to press Vol+ for 3 seconds but after that I again end up on the Error screen.
Thanks anyway.

Use Fastboot in order to find out what version and cust he has. From my experience with other users (from P30 threads and P30 pro threads), if they had EMUI 10 on top of EMUI 9.1 preload and cust, some of them could acces the EMUI 9.1 eRecovery from where they could enter some safe mode called Emergency backup which got them into system and managed to get connected to PC (see my SS bellow) or their Google account and create a backup of their stuffs.
For how to find out his device and info (what he has on it know), please check this link and use the following commands:
fastboot oem get-build-number
and press enter button
This command checks the version, cust and actual firmware of the phone.
If this still not working, i'm affraid that there is nothing else he could do, just have to use a dload firmware in order to revive his device, but by doing it, it will wipe out his data. Even if Huawei Service Centers change his motherboard, they can't recover his data from his actual motherboard...
Let me know his cust and if he is willing to flash a firmware in order to revive it, BUT with data lost, so i can get you a dload firmware for his phone.

Hi SilviuO,
thanks for your help and sorry for the late feedback. Was out of the office these last days and the device was in the office.
Fastboot gives me the following : 9.1.0.168 (C431)
Thanks
I have my brothers phone which has been dormant for a couple years. He wants to use it again but forgets the unlock pin. How can I reset the phone e.g. through recovery mode etc. (by the way, I can't enter recovery mode from off state using power and -vol)
Can anyone help step me through it?
N.B. I can not use the main menu
Cheers
Wanting to root the device via magisk, I tried first to unlock the bootloader of my phone but apparently failed.
I started by activating the developer mode, set oem unlocking developer option in the settings then tried adb reboot bootloader : no success, the phone simply rebooted. A fastboot oem unlock just hung out waiting for a device.
I can go into download mode or recovery mode if that may help...
Any idea how to unlock this bootloader ? How can i check it is effectively unlocked ?
Thanks in advance for any help
It's well known that SAMSUNG mobiles don't have the Fastboot feature: there it's the Download mode.
FYI:
Power off your device. Press Volume Up + Volume Down and plug in your device to a PC to boot into download mode
When you enter download mode, Long press Volume Up button to unlock the bootloader.
ok well, let's forget about fastboot command then.
I'll answer myself on the original question, to unlock the bootloader:
switch off the phone
press volume up and volume down key
plugin a usb cable
choose "device unlock" with a long press volume up
after released the key up, choose "unlock" with volume up again
Now I'm looking to enter the download mode which I can't reach anymore. Any idea xXx yYy ?
Answer myself again
Apply the 3 first steps of my previous answer, you'll be in the same unlock screen as before but the first option will be "Continue". Choose it with volume up and you will end up in download mode !
Now I'll try rooting with magisk...
Rooting with magisk 25.2 done by a classical patching of AP from november release: AP_G736BXXU1BVK2_G736BXXU1BVK2_MQB58744363_REV00
It appears that this is the only thread on the entire forum for this phone?
Having just bought one for the removable battery and the dual SIM, I discovered that samsung in their infinite wisdom disabled the multiple users feature in their oneUI ROM, which really sucks because that was part of the reason I wanted the phone, to segregate certain apps into their own user account.
This all made me realize Root + custom ROM is probably the only way I will ever get that basic functionality returned.
So here I see that rooting is doable, but there appears to be zero results for un-samsung'd ROMs.
Which market is G736B? I was looking at ordering but I am in the US and the Samsung site is giving me the SM-G736UZKEXAA. Would the classical patching work on that?
The G736B model is sparsely distributed in EU, Asia, Africa and Oceania (see here). Your G736W US model is also based on Snapdragon 778G, it is probably the same phone with a few subtleties concerning 5G support (if any, can't find out) and software bloatware. I'd be surprised the above patching doesn't work but ... it's only a guess !
