Lenovo A820 (I just want to root it, nothing else)

Hi guys
All I want to do is root the phone (not install a custom ROM).
All instructions I have read seem to lump rooting with a custom ROM. I have no interest in custom ROMs at this time (The manufacturer's seems good after I switched it to English, but rooting will give me more control over what stays and what goes since I need to clean it up more).
If it matters, the build number of my phone:
A820_S139_130422
Running Android 4.1.2
A few concerns
~~~~~~~~
* Do I need Lenovo's 'stock' ROM? All links to Lenovo's 'stock rom' seem to be on third-party websites (which concerns me). Is this not available from Lenovo's webiste? Is there no way to back up my current ROM?
* Is a 'one-click root' recommended? I'm not even sure if I need the manufacturers stock ROM saved or downloaded since I have seen some posts about 'one-click root' with some utility that can root MTK-chipset-based phones easily. Is this the approach I should be taking? (I don't know if the information is outdated or new or the best practice or the worst practice). Honestly, the more I read, the more my head wants to explode. Incomplete instructions....lots of concerns about back-ups, IMEI, camera not working properly, updates, etc. I want to avoid all the bad things.
* I don't care about Google Play store or *any* Google (NSA) stuff being installed on the phone. I truly couldn't care less about it. So again the manufacturer's firmware is fine for me, but I want to get rid of more silly apps they installed, not just disable them.
* I did manage to root a phone in the past (a Sony) but the instructions were completely different to this phone. I had to unlock the bootloader, then root, etc. Suffice to say, I'm a bit lost again even though I have read for hours.
In summary
* For now I just want to use the manufacturer's firmware but I would like root access for more control over what stays & what goes.
* My only interest is in rooting the device, not installing some developers custom ROM (as nice as they may be, I am not prepared to move to a custom ROM yet).
* I'm not sure if I need to back anything up, take my SD card out or sacrifice some goats to get this thing rooted. Or if it's a lot more simple than that, and I'm just overcomplicating things?

use Framaroot to root it... i successfully root, then flash recovery and repartition the internal memory using MobileUncle...

Hi michael9413
Thanks for your response.
I'm happy to say I rooted it some time after my post (but before you posted about Framaroot. I will keep this in mind for next time).
For those that are interested....it's possible to root the phone and keep the stock firmware on there.
For my case, I used:
Motochopper: Android root exploit (Windows version) v1.0 by Dan Rosenberg (@djrbliss)
Apparently this works for many MTK phones (like the Lenovo A820) and this was the 'one click root' I was reading about earlier.
Of course I had to download the Lenovo USB driver and do the usual things to get the phone detected. Anyway, I'm really happy that it's rooted since there was so much background stuff that I was keen to get rid of.
I still haven't removed the logon/logoff operator logos but I guess that's a job for new firmware. Maybe I'll do that eventually but for now I'm happy to just run it as it is, but with root.
Thanks for your response, and I hope this helps someone out there.

SM-P600

Hi All
Let me start with few good things here You guys are amazing helping and providing tweaks for us:good:
I am Nexus user. I have Installed Custom Recovery, Flashed ROMs and rooted my Nexus 4 and Nexus 5. This is my First Samsung Tablet. I have waited enough for Nexus 10 (2). I finally bought SM-P600.
I was trying to find an Guide with links for Unlocking bootloader and Updating firmware and then flash Custom recovery for this but coudnt figure it out
I have been reading lots of things about Knox and counters related to it.
Can anyone Please help me find answers straight.
1) Any Rooting and Custom Recovery tools or ADB commands without Hitting the KNOX counter {Just In case IF I wanted to return it} If not then which one you recommend ?
By the Way I found few posts related to Rooting Which has confused me more. I used to use Chainfire SUROOT:
Rooting using CF-AUTO Root
Universal Root de la Vega
2) If I Root and want to use Stock ROM of SM-P600 will all apps work normally or any known issues with it ?
3) Is Odin any tool which everyone is taking about ? I am not sure about it Can you provide any links to its dev for more info. Found it about in a Post to return to STOCK ?
4) Are these ROMS and apps Odexed or Deodexed ROM?
5) Any Dependencies for Firmware and with any of the above questions. I mean In Universal Root I saw they were talking about certain version of firmware. Also Should I update the latest firmware and do a Nandriod backup ?
6) Also read that once KNOX counter goes up, I wont get any OTA ? My Plan is I will use it till next Nexus and will give it to parents with stock ROM. If I am using I can always use an Custom Rom and get updates. But for parents I want to return it to stock so that they can easily update when OTA is available.
I would like to make one more suggestion to MOD's Please Pin the Guides like the Rooting and stuff like Return to Stock which are quite common and useful so that its easy for newbies( aka for Samsung) like me.
Thanks
Zaib.

1. This is not really a single question with a single answer I think vaguely what you are asking is if you can root without tripping knox?
Nope. Not at this time.
2. If you use CF-Auto-Root you'll likely find that the vast majority of applications keep working without issue. Of those that don't, a handful you can manage back to a working state with various tweaks, but there are a few that are probably gone for good. You can basically kiss all the Samsung hub apps goodbye, these will start claiming they are not supported in your country even if they were working perfectly prior to rooting, some may continue working for a short time after but eventually something leaks and your access is cut. Screen mirroring will no longer work though this can be fixed with a small zip file flash. OTA updates are also gone.
Forget all the talk about 'triangle away' fixing any of this, it hasn't for me.
3. Odin is a tool that is able to flash firmware files or parts thereof to your device. Heimdall is an alternative suite of applications, while there is a GUI for it, it seems fairly hit and miss on Linux these days, I've never had much luck with it, on the other hand the command line tools work perfectly fine.
Once you trip Knox, there's no turning back! You won't lose your warranty in any meaningful way, but you may end up having to argue about it and drag in government regulators to get your tablet repaired free of charge depending on the dealer response.
4. I don't think this is particularly relevant to the SM-P600. My subjective opinion would be to stick with the bog standard Samsung ROM. If you want cool themes there are a multitude of launchers, Xposed takes care most other things you might ever care to tweak.
5. You have one choice. CF-Auto-Root. Backups are healthy.
6. True, but you'll still be able to flash via Odin so it doesn't really mean much of anything. Once you trip Knox, you can also kiss OTA updates goodbye as well.

How are you flashing TWRP, through recovery or Odin?

Difference between rooting and CyanogenMod?

Hello guys I'm a total n00b when it comes to rooting and such and I have a question, that most of you guys will probably find dumb but I'm seriously confused.
I ordered the Zenfone 2 with 4gb ram & 64 gigs of storage and I plan on rooting it once it arrives.
What is the difference between rooting your phone and installing a custom rom such as cyanogenMod?
What are the benefits to both and the main difference?
Is one easier to do and is less risky or what?
Please explain in a way I can understand, thank you!!

Rooting the phone means you can modify the system files. It's useful because you can add or remove features of the stock rom on your phone (theme manager, ad blocker, and almost anything you may need)
Cyanogenmod is a rom based on AOSP (Android Open Source Project, by Google), it's rooted, and comes with a lot of features that are not in AOSP.
For the moment, there is no Cyanogenmod rom for our beloved Zenfone 2, and maybe it will never happen. But only time can say.

well.
Rooting mean to gain Super User (SU) to your phone, it mean that you are the master of the device and you can overwrite anything because you are the hierarchy top. ( this is also why device tend to be bricked by noobs because rights(permission) given to change anything.
Top mod of android currently are cyan and MIUI
Cyanogen is a custom rom which build on top of the default Android. it come with root and you can basically manage any part of the phone, it remove many bloatware and just clean and open android OS that look like a default Android.
MIUI is another custom rom, similar as cyanogen but it's appearance look like Iphone and behave similar as Iphone. ( they are the Iphone wannabes) its also clean.
well, don't root because you just want to, root because you need function that require you to. mostly without root, you can do many stuff such as installing unsigned apk. unlike iphone, which must root to install unsigned apps.

So if I download a custom rom such as Cyanogenmod is it easier to update software? Or do I still have to unroot to update OTA and then reroot?

A custom ROM such as cyanogenmod would replace the Stock firmware, so you would not apply ota updates. Instead, the updates would come from the ROM maker.

Thank you so much! Makes complete sense!

Simply put
rooting allows you to change system files. CyanogenMod is a bunch of files that need root so they can be applied..
But since CyanogenMod is not out for Zenfone 2. I would not root it yet. Rooting can cause ASUS updates to fail.

when you apply custom rom to your phone ( be it Cyan or MIUI), they become your "phone manufacturer"
why i say that is because they will release the software update to your device instead of Asus for instance if you gotten zenfone 2.
with that said, most of the time, custom rom is better then official rom however, if the custom rom group stopped patching and your phone might still have some bugs.... you are on neck held by these groups. while it is the same for Asus but they are a company which they are being held legal for updating any flaws to your phone till end of life of the product.
there are good and bad, if you want to come into the scene, then make sure you are always up to date with what is and what not.
this make you strong in modding your phone and knowing what is going on too. and also... if you aspire to be a system engineer, this is 1 first step too. handphone is a miniature eco-system of how network works, while you start modding and deal with unix command, that is what system engineer does.

I guess it's not for the faint of heart. But as long as you restore the /system back to stock by flashing pre-root, unrooting, and uninstalling xposed, then you won't go wrong.

Installation of CyanogenMod don't need root, they need unlocked bootloader and recovery that's all.. Root is needed only for editing system files

Android Pay Custom Roms and Magisk

I use Android pay frequently thus so far have yet to root this device, (i did once and learned about how it wont work). At that time Magisk was just released and there were other hide root type things than just seamed too much of a hassle, (rebooting into non root mode to use android pay).
From what i have read recently that Magisk helps with this and there is also a systemless xposed, The only howto i have found on the subject is https://forum.xda-developers.com/oneplus-3/how-to/guide-oneplus-3-magisk-install-android-t3433093
are there any non rooted custom roms to use in this way?
I appreciate your help I have always loved customizing my phone but the whole android pay thing sucks, if only i didn't need it.

XPosed won't be there yet if you plan to use Nougat. Only <= Marshmallow has a working XPosed up to now. But yes, Magisk is really nice, I am using it with the included root variant + ViperAudio + WIFI 40 MHz Unlock + Google Assistant enabler and all systemless. Working great on my OxygenOS 4.0.3. Due to francoKernel Google Pay does not even see the unlocked bootloader and thus works (in theory... not really of any big use in Germany yet) You just need a Custom ROM without any root OR you have to remove root by yourself. Search for unSU, a ZIP file somewhere on XDA which removed system based root by TWRP flash.

Is it worth to root your Samsung Galaxy S10+

Hello,
Yesterday, I successfully rooted my Samsung Galaxy S10+. But since I still had some questions about it, I went on and posted a thread here. User Spaceminer then pointed out that my original post was in the wrong subforum and linked me here. Naturally, I looked at some of the most popular posts in hopes to find answers to my questions. But what I found confused me more than it gave me answers.
Since 2014 with the Samsung Galaxy S5 I got used to rooting in order to disable bloatware, protect my data and customize my phone. I continued doing that with the S8+ until I recently got my hands on the S10. Now, my main reason for rooting are still the same; I want disable (not necessarily uninstall) bloatware, protect my privacy and customize my phone (such as changing the background of the dial when calling someone). But that thread made me wonder if it is even essential to root. I also found a similar post on reddit and most answers seem to agree that it is not necessary to root your phones.
Now, my situation is a bit different. For one, I already rooted my phone. Second, I don't care about warranty nor custom ROMs. But I do want to install a banking app. Also, it is a bit cumbersome to not only have to manually update your phone with every update but the booting requirements with the warning screen are also a bit annoying. So, my question is the following:
What are the advantages of rooting that are not possible without? I have 3 main concerns: Bloatware, Privacy and Customization.
The reason why I posted this in a separate threat is that I was not able to come to a definitive conclusion on my own and most discussion threads are over a year old. By now, the whole process of rooting and what is possible changed since then, so I want to get a more recent insight. I hope you can help me out.
With kind regards,
DasMalzbier

Tbh root is not needed, unless you want to use a custom rom. Most things are already in the android now.

Calyx os not make for samsung Galaxy series and 12 update also comes this year so i think rooting is unnecessary for s10 series

Root is 100%, absolutely necessary for using the phone. I cannot use any phone without it. Critical root-only capabilities:
full system backups (in twrp)
titanium backup
disable updates permanently (update ONLY when want to)
app freezers (app quarantine)
disable/remove bloatware
disable google play services/google play
automate/tasker
cf lumen
adblockers
wifi tether
busybox
superuser
ssh tunnel
update android to later version / install custom roms
optimize system
button mapper
custom theming / substratum
nav gestures
tidypanel
xposed
root explorer
app privacy customizations
3c all-in-one toolbox
more
Without root, the phone is unusable to me. I will never buy any phone without root capability. I am willing to go to different carriers just to get root on the device, or go to different manufacturers if root is blocked. For example, I will never buy a huawei device - they are locked.

I would like to say yes but I can't. the stock apps are very well designed.
The biggest concern is that custom Roms are released faster than modded apps.
For example I tried about ten GCAMs and all of them have a bug... and it becomes more complicated with Exynos.
OpenGcam is not worth samsung app.
Unable to get voice match to work.
Alarms that you can't set to a specific day with the google app.
And so on.
Root is useful when the manufacturer no longer updates the devices.
I regret having Root mine because I lost Samsung Pay and other things.

The only one that would have any consequence of rooting is Samsung Pay.

No, even if you wanna use custom rom you don't need to root. Just pick the rom with the apps you want or just use the gapps packages you want, if want essential to work gapps then use pico or nano. If there is still something you want to remove and the romdoesn't allow, just use adb shell commands and thats it. Less issues with banks not working because of Magisk (root). I know Magisk has a feature to hide itself, change its name but depending on the app, the libs can be found and know that is Magisk, so for security purposes some apps don't work and some aren't even shown in the Google Play Store just because you rooted the device.

maybe now the root is not needed but later down the road when your phone will get obsolete and newer android OS updates will be halted for S10+ then you'll be more attracted towards custom roms. Actually it is just personal preference.

It's happening right now, I doubt S10+ will receive Android 13 and now just security and bug fix updates are being shipped by Samsung.

It won't get any new Android upgrades AFAIK.
But appart from tripping knox, what else do I lose if I unlock my bootloader? I read once, quite a while ago, that the battery is limited to 80% of its full capacity. Is that true?

Depending on the version, you'll notice stock camera to be limited or not work as expected, secure folder, dual messenger either not working, it can trigger some banks or payment apps (especially if you root), no more ota updates (if you keep using stock rom), drm content can stop working, samsung pay, Play Store might limited the apps you see and so on... Not sure about the battery, for me unlocking the bootloader and switching to another rom made my battery last more than stock, but it depends on the rom, the device, it's not a rule of thumb.
