Unlocking bootloader SM-T377V - Samsung Galaxy Tab E Questions & Answers

Looking for ways to unlock the bootloader to gain full root access I've already downgraded 7.1 to stock. Debug,oem, and USB options all enabled. Everything it reboots root is gone. I've tried and but it will only reboot the device nothing else. I don't have a sim card in it and when I get into recovery it said failed to find partition and dm-verity failed. Any help would be appreciated!

Stuck in bootloop with usb debugging disable, locked bootloader, all stock non rooted

Am I completely out of luck. I try to run flash.bat from a factory image but img flash fails because the device is locked. I can't find any way to unlock it without getting into developer options which of course is impossible in boot loop. I've tried Wug's tools to no avail. Does anyone know of any way to unlock bootloader without getting into settings to enable usb debugging? Any help is greatly appreciated.

There's no way you can unlock the bootloader. If the phone is stock with no modifications you can try using the stock recovery to adb sideload one of the full OTA updates. Check out section 13 of my guide here:

LG Stylo 2 unable to be recognized in recovery

New to XDA so sorry if i posted this in the wrong place
But recently i received a new phone, an LG Stylo 2 Boost Mobile. It recognized fine while it was on through adb, but when i turned it off and booted into recovery, it wouldn't be recognized by adb, nor fastboot, and when i tried to "reboot into bootloader" it only restarted the whole phone into its normal boot. Adb sideload worked but i had no idea what files to try due to a locked bootloader and no stock ROMs found anywhere. I tried kingroot and it didn't have any ways to get an instant root. Im running Ubuntu and the phone is on 6.0.1 Marshmallow. Any ideas out there? I'd be sure to give them a try
The phone would only be accessible in recovery via the adb sideload option with stock recovery.
What exactly are you trying to accomplish?

I'm trying to unlock the bootloader so i can flash a new recovery then root won't be hard to achieve, but when i try to access the phone in recovery mode, it doesn't recognize whatsoever. I thought there would be something i could do with sideload to somewhat downgrade the system and gain some type of bootloader, but that didn't work. Is there someway i can flash a custom recovery?
Don't believe there are any options for unlocking the bootloader or a custom recovery for that phone. According to what I could find in a quick search, there is root available but only on the software update ending in ZV3.

Alright, thanks for the info, wasn't sure if there was a way around it or not

No Recovery

I think i made i grave mistake. I want to upgrade my p9 lite to nougat so I decided to unroot my phone. The unrooting is successful with the device still booting. So next thing i want is to flash back my stock recovery so I can update my phone through OTA (this is where I made a mistake.) I tried doing it by flashing a full MM Rom that i got directly from huawei through dload method. The flashing went smoothly or so I thought. My phone got stuck in a boot loop and I cant seem to access recovery. eRecovery is also inaccessible so I tried reflashing the full MM Rom through dload method but I can't get it to work anymore. I tried it several times with no luck. I also tried reflashing meticulus' twrp through fastboot method but I always get an error saying "remote command not allowed". The bootloader is still unlock btw.
Someone help me. I don't know what to do anymore... :crying:

The bootloader appears unlocked, and says so, but it's not...I encountered the same situation with my colleagues device, you need to unlock it either way(careful this will wipe all your data if on nougat, but if on MM after unlocking keep phone connected to PC as it reboots and quickly press vol down+ power to get back to bootloader In order to flash TWRP, this will preserve your data partition and system), and try again, you need format that data partition by using changing format to f2fs then ext4...after this reboot, if it can't, reinstall the file In dload folder and go to stock recovery(disconnect phone from PC to do this if it fails) and do a factory reset.
.... if this fails, debrand And install MM or NOUGAT for your newly debranded system.
If this fails, which is highly unlikely,PM for un orthodox methods.

The problem is I cannot access recovery anymore. After trying to flash back full rom from huawei, i cannot access recovery anymore no matter how hard i try. eRecovery is also not accessible so i cannot turn off my phone. I tried flashing twrp trough fastboot i keep getting an error saying "remote command not allowed". Dload method is not working anymore. If only I can find a way to flash twrp, then I can restore the dump i made using meticulus' twrp.

Assuming that you have the unlock code, what happens if you try unlock bootloader again irrespective what status it is now?

It shows in fastboot that the phone is unlocked with frp locked. Unlocking it again through fastboot is not possible since I always get an error saying remote command not allowed.

Hi guys, i Got the SAAAAAME Problem, this is all about what i PMd to you danerrickcuba FRP lock and bootloader unlocked. can't go to recovery, but has access to fastboot and wasn't able to do anything to fastboot.
Already fixed my phone. Had to pay 15 euros for DC Phoenix (this software saved me from bringing my phone to huawei service center to have it fix. Thank god!) so I can fix my phone. Recovery, eRecovery, Dload method working, and relocked bootloader. Currently updating my phone through OTA. Tnx danerrickcuba for suggesting methods to fix my phone....

i have the same problem
bootloader unlock and frp lock ,bootlooping,rec&e-rec destoryed
if you do not log out google /shut down "find my phone"/check oem-unlock in developer mode before downgrading or flashing ,you will get "frp lock" warning
bootlooping may come from wrong update.app. eg. i use dload method to flash rollback(5.0-B300) pkg in EMUI4.1 , my rec and e-rec are destoryed
however, i think fastboot command could do nothing to "bootloader unlock ,frp lock,rec and e-rec destoryed ". i do not know how DC-phoenix fix this and i pay a new motherboard for my mistake

How to root Xperia L1?

I typed the code into my keypad and it went to system settings and it said I can't bootloader unlock this phone. Apparently I need this to grant permission for root. How do I root this particular phone? I managed to get a systemless root on my galaxy s5 by using TWRP to flash Majisk, although TWRP doesn't work for this phone. How can I actually root this phone. I would prefer to root with Majisk but honestly, I'd appreciate to know any way that I can really. Much appreciated!
if the unlock bootloader ALLOWED : is NO
then sorry sir
you cannot root this device!
There is a version of TWRP recovery for this phone which you have to flash to the boot partition, but I think in order to do this you need to have your bootloader unlocked. If your service menu says this option is disabled, then you're out of luck. :/ Sorry.
1. Go to Sony Developer site. Get bootloader unlockin code for your IMEI.
2. Dowload flashtool 9.25 with drivers.
3. In Developer menu tick allow OEM unlocking and USB debug.
I did it for my. It was not allowed to unlock bootloader first, but flashtool does it (in two steps)
i unlock the bootloader ,but i cant root this phone.
i try many ways but its faild.
plz help me to root my phone
old post I know, but did you get this rooted at all? as I have the phone (5 years now) and want to get a different OS on it to de-google it - but I'm new to it all, I have flashed firmware on other devices but never ventured into mobiles
cheers

Can't get into TWRP mode on my Samsung Galaxy S8

I just installed TWRP onto my Samsung Galaxy S8. It was installed successfully, but when I try getting into the TWRP mode by pressing power+bixby+vol-up, the phone vibrates and displays a pink light at the top left before returning to a normal boot-up screen and my phone unlocks normally. When my phone is done booting up, I get a grey box saying:
"
[PDP]
back-up : fail
setup-wizard [FINISH]
"
I suspect this has something to do with the fact that I've gonked up the phone a couple of years ago. I had to send the phone to Samsung to get it fixed, I stayed away from rooting until now when I've gotten a new phone. What I'm asking here is, is this the cause? And how do I fix it so I can get into TWRP mode so I can complete my root?

How do I unlock my bootloader? Does it imply, having gone into the bootloader mode before flashing TWRP? If that is the case, no, I hadn't gone into the original recovery mode before flashing twrp, if not, what does it imply? Also, how do I fix?

You mean to tell me that in the process of finding and flashing TWRP for your device, you did not see anything telling you that you had to make sure the bootloader was unlocked before flashing it? If you didn't then you did a poor job of researching the process of flashing TWRP and rooting your device because it is usually mentioned in all guides for flashing TWRP.
No, I meant, did you check to make certain that your bootloader is unlocked before you flashed TWRP? I asked about bootloader because you can't flash anything custom if the bootloader is locked.
I don't know if your bootloader is locked or not. Just because I'm asking, does not mean that was locked.
If it is locked, you have to unlock it and then flash TWRP, if it is already unlocked, you do not have to unlock it.
Unlocking bootloader on Samsung usually involves enabling the OEM unlock setting in the device's settings. Enabling this setting does not necessarily mean that your bootloader is unlocked, you also need to boot into download mode and check the RMM or KG status to see if it says "prenormal", "checking" or "unlock". If it says "prenormal" it is locked and you can't flash TWRP.

I did turn on the OEM unlock before flashing. Did not see the RMM or KG status though. The flash was successful though. It just doesn't want to open TWRP as it cancels and shows me a pink light right as it's about to open TWRP.

The information on the S8 are really poor. I used to root a lot of phones until a few years ago. Finding a manual for the S8 (Rom install, first TWRP,...) Seems to be impossible. I just find many contradicting information.
One manual sais there is nothing to unlock. I shall just use Odin to falsch the rom. Done. Other manuals go by TWRP as I know it. And so on.
