Before I decided to switch from iOS to Android, I heard all about people who jailbreak iPhones to escape Apple's walled garden. I never understood the appeal, personally. It wasn't until I started testing out Android launchers that I learned about the joys of customization compared to Apple's static, curated iOS experience.
But I'm no hobbyist, the kind of person who tugs at loose threads of technology to see what breaks before fixing it. So I have to admit to a bit of imposter syndrome when reading how my colleague Alex Dobie installed Android 11 on his old Galaxy S2, or how Andrew Myrick used to root and install nightly ROMs on his Nexus 4. I use Android phones constantly these days, but I don't have a decade of experience rooting in the OS's backend to call upon.
With these insecurities driving me, I started reading up on Magisk, ROMs, and rooted apps. My main goal: get root access and flash a new ROM on my OnePlus 7 Pro while getting no help whatsoever from my colleagues. I was curious if someone without any experience could succeed using only the online resources available to me, or if rooting and alternate OSes are better suited for Android veterans. Plus, I wanted to decide, is rooting Android phones in 2021 actually worth the effort?
Long story short, my multi-day hackathon was a stressful mess, including a Fastboot loop, several false starts, and broken TWRP image files — ending in a partial victory that came with a free tension headache.
Stumbling in the dark
All of my casual root reading suggested that XDA Developers is the best mainstream authority on this topic. So I tracked down their OnePlus 7 Pro rooting guide, tried my darndest to follow the steps... and immediately ran into difficulties.
Look at some of the steps, presented without elaboration: "Reboot into your bootloader." "Flash TWRP." "Set up adb." What on earth does any of that mean? What's the difference between booting into your bootloader, fastboot, or recovery mode? Where's the glossary?!
After some flustered background reading, activating my phone's Developer Tools and installing Android Debug Bridge (ADB) commands didn't prove especially difficult. I have experience with Terminal commands, and (some) Android phones make it surprisingly easy to access the bootloader. But things grew much more dangerous after I unlocked the bootloader.
XDA told me to run TWRP with a "fastboot boot twrp_file_name.img," using a linked TWRP file for Guacamole. I did so, at which point I got the above "Fastboot mode" logo. Progress? Nope! It stayed frozen on that screen for hours before I figured out how to send the phone to recovery mode and reboot to factory settings.
During my second attempt, I noticed some sites recommended switching my A/B partition and using fastboot flash boot file_name.img instead. This time, instead of booting straight into TWRP as promised, my phone went into the generic bootloader. Worse, it didn't matter if I shut it off, switched to recovery mode, or tried to install a new img file; the phone would immediately switch back to the bootloader. My previous recovery mode shortcut didn't work, either. I was screwed and frustrated that my hard work wasn't paying off.
Even more hours later, thanks to some panicked forum posts from people experiencing similar issues, I managed to escape my bootloop hell. But after two days of research and stress, I knew I wasn't going to make TWRP work for me. So I switched over to the LineageOS wiki to see if I'd have more luck with the popular ROM.
In this case, I'm happy to say I mostly succeeded. I flashed the LineageOS ROM and then installed it from recovery. I also attempted to install a custom Google Apps (GApps) suite since third-party ROMs don't get access to the Play Store. After a few more steps, I did finally reboot into LineageOS. But for whatever reason, the GApps Suite didn't take, limiting me to its pre-downloaded apps and whatever safe .apk files I downloaded online. And LineageOS removed superuser access in 2019, so I'd still need to install Magisk Manager or give individual apps root access over ADB.
But at this point, I was pretty mentally drained, nursing that headache I mentioned earlier. If I did have someone walk me through installing Magisk in person, I'm sure I could get my OnePlus 7 Pro rooted fairly quickly. But it does seem like most of the rooting guides in 2021 assume you already have a thorough background in the hobby.
Now, I'm trying to decide if rooting is worth the effort in the first place.
The dangers of rooting and ROMs
To get to the root of the problem (pun intended), I reached out to Danny Lin, who develops the ProtonAOSP custom ROM for Pixel phones. He also made waves for recreating the Material You theming engine as open-source code during the early Android 12 betas. If anyone could give me an informed opinion on the risks and justifications for rooting and ROMs, it was him.
"I wouldn't recommend rooting or installing a custom ROM to most 'normal' users who just need their phone to work," Lin told me. Although "permanent bricks are very unlikely," he notes that many issues with ROMs are "out of the control of ROM developers," such as when Google breaks SafetyNet.
So you need the patience to deal with occasional but inevitable breakage, plus the know-how to recognize when something goes wrong and the willingness to take the time to fix it. That's why you need "experience with modding mobile devices" to handle ROMs safely beyond the initial installation.
As for the dangers of rooting, Lin didn't beat around the bush about its dangers:
Despite that, Lin finds root to be "invaluable" as a developer for testing and debugging, and thinks it serves a purpose for tools where stock Android "falls flat," such as full data backups. And if there's a "root-exclusive feature" you want, "it's probably worth the risk" to try.
Is rooting a dying art in 2021?
Plenty of Android Central readers have left nostalgic comments on how they used to flash or root their phones, but don't anymore. I asked Lin why rooting Android phones in 2021 might be more niche than in the past, and he had a host of reasons.
First, "stock Android has also gotten more powerful," but beyond that, many third-party Android apps have found ways to implement missing features without root access, preserving your phone's security. Lin also noted that modding is "more complicated" than ever before because of recent Android advancements like "seamless A/B updates and dynamic partitions."
So older Android enthusiasts give up on root and ROMs because of the increased difficulty for diminishing returns. Meanwhile, new Android fans don't replace them because of the steep learning curve.
"Flashing can be quite daunting for new users because there's so much more room for failure in the process than there used to be," Lin said. "It's a lot of steps, and missing one small detail can result in a soft brick that people don't want to deal with." His words were so accurate to my own experience that I could only laugh to myself.
If I had succeeded in rooting my OnePlus 7 Pro, I had planned to test out apps like YouTube Vanced, AdAway, Tasker, and others that use root access to great effect. With these apps, you can add tools like a recycling bin or terminal access, better monitor and control your energy usage or background app activity; or remove unwelcome ads from apps.
Frankly, though, most of these aren't vital tools for my daily phone use, which mostly involves casually playing Android games and checking email. Given the serious vulnerabilities caused by opening the Pandora's Box that is root access, I'm not sure if I'd say these tools are "worth it" to me as they would be for other power users. Plus, as Lin said, you can get some of these tools now even without root access!
I may attempt another run at rooting in the future, simply for knowledge's sake. But I think I'm increasingly more interested in installing new ROMs like ProtonAOSP and LineageOS, because they add cool tweaks and optimizations to your phone without turning it into a ticking time bomb.

Like many, I was a committed custom ROM enthusiast. The LG G3 in September 2015 was the last time I done this on a personal use phone - I even hacked the hardware on that one with additional cooling to help the SD801 CPU. My next Android device was the OnePlus One, a device built for hacking.... but it didn't need it, so stock it remained. And I've never gone back as I don't need to, it's nothing against the romming scene. I had the first 4 Nexus devices and they had to be hacked as the software was rubbish, my personal record was installing Cyanogen Mod on the Nexus 4 in less than 30 minutes after opening the box.
I do look in on XDA and it's good to see things are still alive.
Stock software (with a few tweaks) on the Nexus 4 was pretty great until Lollipop, that's when it got ROMmed for me. Rooted it out of the box though.
"Is rooting Android phones in 2021 actually worth the effort?" No.
I always root my phone. I research whether a phone is root able before I buy it. I root it so I can install AdAway and remove bloatware.
I've got tons of great memories of rooting my phones. Been an Android fan since the T-mobile G1 and used Cyanogenmod for many years. I stoppes rooting when apps like Snapchat and Pokemon Go stopped working on rooted phones. Also installing AOSP roms on Samsung phones are either impossible or reduce functionality (ex: worse/no camera support).
I stopped when banking apps stopped working on rooted phones. One of my major uses of my phone was gone.
Ive got many happy memories of many ROMs, the key to it all used to be making sure the USB driver was correct lol
The first devices I rooted were a B&N Nook Color and HTC Inspire 4G. Not exactly entry level and didn't really know what I was doing, but I got lucky and managed to get through those w/o bricking anything. Last rooted device was my Nexus 5, with many in between.
I just want to say I'm extremely proud of Danny. All of his points are spot on, and this is one of the few articles that actually addresses the pros and cons of rooting in the modern era of Android phones. I also want to shout out his Patreon. I'd love to see more support on there as he definitely puts in the work.
I think you picked the wrong phone for your first rooting attempt. The OP7/7 Pro changed things a lot and it took a bit longer to get them going. You would have done better to start with the 6 to get your feet wet. I've been mucking with phones since 2007 (HTC, Motorola, Samsung, OnePlus) and I've learned to lot. Many have been doing it for years, so unfortunately, there is a lot of assumed knowledge of the basics such as ADB, fastboot, recovery, etc. And a lot has changed over that time as tools and methods have changed. Add to that the fact that each vendor does thing differently and it can be a headache. Especially with some of the kludges needed to be done to get around the locked bootloaders on many Samsung US editions. The biggest thing to do is research, which you've done, but it often involves searching threads and often rereading them multiple times to understand. Even then, it's possible to make mistakes. But that's part of the learning process. I've soft-bricked my phone multiple times, and it feels like an achievement when you fix it. If you don't understand, the biggest thing to do is ask. There will be people who tell you to search, and a reasonable effort is expected to be made in that regard. However, if you still don't understand something after doing the research, feel free to ask and mention that you did your homework but you're not understanding. Most people are much more willing to help when they perceive you're not a lazy noob just trying to take the easy way out. I still root. I find the carrier/OEM roms to be too bloated. I hate ads, and even using a VPN based ad blocker was problematic and slow for me. I had flashed back to a T-Mobile load for my OP9 and I absolutely hated it. Root gives me the choice to add the things I want, customize how I want, and do what I want. Magisk hide still lets me used all my banking and GPay apps with no problem. Magisk hide of course is up in the air now, but for now, everything works for me. The ad blocking alone, for me, is worth it. Rooting isn't for everyone. Lin's points are pretty accurate, and if you're not that technical and comfortable getting down and dirty with the phone, and don't have the patience to deal with things going wrong, you're probably better off leaving well alone. If you're phone does what you need it to and you're happy with it, then enjoy stock. I just hope at least some OEMs and Google at least leave the choice to unlock and root if you want. A clean, debloated ROM is a wonderful thing.
