[Completed] Unlocking Bootloader (RCA Tablet)

I'm entirely unsure if this is the correct area, but I need help, (Correct me if this is the wrong area for this), I have a RCA tablet, model RCT6378W2, android version 4.2.2, its rooted, (I used a app sadly, kingoroot, it successfully rooted it, but its loaded with things from it now such as superbattery, etc, though, I hopefully can get it removed). BUT my question is, how exactly do I unlock the bootloader on such? I want to put a different operating system on it, hopefully a more up to date one, and with less restrictions, and less, y'know, google.

Lenovo phab( not plus) need help for rooting.

I have been trying to root Lenovo-phab-pb1-750m and referred here http://forum.xda-developers.com/general/xda-assist/root-root-help-lenovo-phab-pb1-750m-plus-t3427518. Well so many deivices in the market are stable to root, why rooting would cause so many problems with this device. Is it dependent on the exploit or the method to gain root access so that device should remain stable to root, without any malfunction. Mine I have experienced hardware keys volume down and power button not responding trying after kingroot. Kingroot which modifies the stock recovery, we will not be able to accept OTA Updates after trying this. I got the issue fixed from an ASC as when I tried reflash using qfil I got sahara error and ended in bootloop.
My main concern is to gain root and it should with full support of su binaries with busy box. Many times it is required to unlock bootloader and install custom recoveries for this I didn't mind doing it. But there is no support officially nor in XDA. But I found one thread here http://www.unlock-bootloaders.racing/2016/10/lenovo-phab-8142.html not sure they are referring to this model but they are referring to XDA site but I can't find it in this site. Are they referring to this model lenovo-phab-pb1-750m in the above thread and can I try it on my device model.
However, I noticed that there is one latest method called systemless root here http://www.xda-developers.com/chainfire-releases-root-for-android-6-0-without-modifying-system/, Hence I want to upgrade to Android 6 and unlock its bootloader to try this. please advice how I can go about. In the mentioned link http://www.unlock-bootloaders.racing/2016/10/lenovo-phab-8142.html there is a method given to unlock the bootloader not sure this is for this model and am running lollipop version 5.1.1. Please check and provide me some info.

Have superuser access but "-su: not found"

I have rooted my samsung galaxy s7 edge from sprint, G935PVPU4BQH1 with some engineering bootloader through odin. I am currently having trouble installing and running kali through the deploy apk. With some searching I found some help for setting up linux but I reached a dead end with a terminal emulator basically telling me I am not rooted with "/system/bin/sh: -su: not found" all I thought i know has been shaken and I see there is no spoon. Please help me root my galaxy s7 edge with the above software version or explain to me why I can't.
this is hard for a noob, any help is much apreciated

Please help ?

Sometimes a root doesn't take. You may have to retry as something could have gone wrong internally even if you followed instructions perfectly.

Sprint version has reported problems.
However, I strongly advise against rooting the device due to this post. If Chainfire has issues rooting the S7 consistantly, a community expert, then any attempts at rooting are purely experimental. At this point you may be able to root the device with a real possibility of a hard brick and no logs to prevent the same for future users.
If you still would like to give it a shot, I recommend reading the links in this post and last few pages of the root thread.

Thanks man I appreciate the link to that post, I still had the same error in my terminal emulator but then my dumbass figured out that there are multiple directories root can be installed in, I checked which one I had with root checker and had it fixed in the terminal, thank you

Rooting a Galaxy S4 (SGH-i337) in 2021

Greetings. It seems the AT&T subforum for the Galaxy S4 might be dead. I was trying to look for an up-to-date way to root this phone with Magisk, but it seems that step one isn't possible since apparently the bootloader isn't unlockable, or might not be one of the ones listed as usable. I can't check which one I have because neither adb shell nor terminal emulator recognize getprop, with the latter not allowing the punctuation. I want to see if I can use the sd card as internal storage, since apparently the Google Play app writes a lot of garbage until the available storage is only 1GB. I found that out by uninstalling its updates. What's the current modern way to use the SD card as internal storage for Android versions older than M?

Don't know what happened, but Retrial edited his post on "S4 Unified Collection!" such that the magisk rooting guide redirects to a guide for Xiaomi phones. Will that really work for the S4?

Forgive me for necro-ing but did you ever find a solution to this?

[Q] 4.3 AT&T root
Hello all, I have a AT&T Samsung Galaxy S4 that just updated to 4.3. Can someone direct me to how I can gain root access? Also, I am assuming that noone has published a way to crack the bootloader as of yet? Thanks in advance for any help...
forum.xda-developers.com

I would like to have an unroot guide for this phone to.
Basically, what I've found in this forum is that you have to "DOWNGRADE" to NB1 (from OK3), and then you can use "SAFESTRAP" of somekind(?) to get a rom, but without unlocked bootloader. I believe, this is going back to Android 4.4.2 or something. Basically, it's forcing to downgrade significantly, which beats the purpose.
I wanted an unlocked bootloader, to get newer ROMs, to increase storage. i.e. use external SD as internal. However, it seems apps don't always allow it to be installed this way, and also causes much headaches - speed is one thing, and data corruption is another etc.
In short, there is NO existing way to circumvent unlocking bootloader. Maybe a professional hacker may do it? NSA? By that point, use that cash to get a new phone. LOL.
Disappointed that this phone is still like brand new, and has plenty more life left, like, 10 more years... it keeps working.

Nice.
Can you please share the exact method you carried on?

Follow the guide here to install TWRP and disable force encryption: https://forum.xda-developers.com/t/recovery-official-twrp-3-7-for-galaxy-a52-4g-and-a72-4g.4405751/
After that just flash Magisk.

Greetings to the XDA Team and all the other good people,
I want to root my Samsung Galaxy A52 4G, and just wanted to ask where should I start so I do it successfully, without upside-down moments. I already updated my phone to the latest, so now the phone is running Android 13.
I am a beginner in this, I educated myself from some videos online and on the XDA forum and saw that I can make my device more secure with root, I can disable system and apps trackers.
So my first question is, do I need to downgrade to Android 12 so the success rate becomes higher or I can stick with Android 13 and still get success for the end goal?
My second question is if what I wrote above this is a truth.
The third question is, how do I get my device running again if rooting fails?
The forth question is, can I unroot my device if I want it at some moment?
My fifth and last question is, is rooting worthy and needed so I can achieve my goals?
I still think I know nothing and want to expand my knowledge, so I ask people who are masters in this field to help me out with this, so I can become happier.
​Thanks for considering my request.

You can do root your phone. But you should not be panic. carefully read instructions and do it with patient without skipping none of the steps.
I'm also not an expert. but i have done rooting of more than 10 phones without failing.
you have to unlock your boot loader before rooting.
I doubt about your statement about device becomes more secure with root. it depends on what you do alter followed by root. yes you can improve privacy.
also your banking apps may stop work after rooting. so you have to apply necessary modules (security fixes) before get them start working again.
if rooting failed provided phone is not hard bricked, you can flash your original firmware to restore the phone. what i always do is keeping all the original firmware ready with me before doing any rooting.
yes. you can unroot by flashing original firmware.
last question is difficult to answer. majority of people use their phones without rooting. if you want to be different, it's up to you.
