[TIP] No-wipe root! - OnePlus 2 General

Hi all,
Just spotted a neat little trick for those who want root on a stock rom without a wipe...
The simplest thing ever - encrypt your device! It appears that a fastboot oem unlock unlocks the bootloader but doesn't wipe the data if it's encrypted!
I had unlocked the bootloader previously but the OTA did re-lock it, but then I needed my work email... Anyway, YMMV but it worked for me.
IMPORTANT NOTE: currently TWRP doesn't support encryption, so you can't backup using that once encrypted. Of course, you can root and titanium backup though!
Note to mods: please move this to OnePlus2 threads, I failed at putting it in the right place!

Thread closed per OP request.

[Q] If i do a nandroid backup before unlocking ?

If i do a nandroid backup before unlocking and flashing a new rom, and then use the back up, will it restore my device and lock BL ? will it at least hide the "unlocked" text ?
You can't use CWM without unlocking first, so nope.
Sent from my MB860 using XDA
So no way to "Re-Lock" ?
Unlocking/Rooting
Ok, so, you can root without unlocking. Rooting allows you to have superuser rights meaning you can change the system. However, without unlocking your bootloader, you cannot boot up a different ROM (a different OS).
I guess if you root, you could then go do a Titanium Backup after installing the app from the Play Store, that could then backup to an SD card (I would then remove it just in case unlocking wipes your SD too!) and you could then unlock and restore your apps and data from Titanium after unlocking. BUT, Titanium is not like nandroid and doesn't backup everything! So backup any essential data twice!
Oh, and relocking is impossible as far as I understand btw, but I understand that you can make it impossible to tell (well other than the burnt out wire which apparently burns when you unlock the device, a permanent change), this can apparently be done via flashing some sbf files and a Fruitcake. But no, when booting a custom ROM, I don't think that you can remove the unlocked text, only when doing a full restore as far as I can understand.
Hope this helps.
Feel free to ask any other questions you have before going for it and I will try to help, but I am sure someone else can be more helpful than me .

[Q] Installing CM-10.2 Android-4.3

Hey guys, I've rooted, installed CWM Recovery, Unlocked Bootloader, and installed CyanogenMod on another phone before.
The thing is, I've had this phone for about 6 months and wanted to do the same. However, after browsing through the forums, man are there a lot of scary sh*t going down. I would like the request the procedure to install CyanogenMod safely, without losing any Keys/IMEI/XReality/DRMkeys/Etcetera.
I dont know if the method given by FXP is supposed to be this straight forward, but I too like others, do not want to risk losing important stuff if it can be avoided (Keys/IMEI/XReality/DRMkeys/Etcetera).
HOWTO
Install instructions:
first time
- power off the phone:
- hold vol+ and plug usb to boot into fastboot (blu led)
- fastboot flash boot boot.img (from cm10 zip)
- fastboot reboot
- enter recovery, on boot led will be violet for 3'', during this period press vol+
- flash rom zip
- flash gapps zip
- wipe
- reboot
for update just flash rom zip from recovery
Google Apps are not included in this ROM. You'll need to find those yourself if you want them.

Frankly speaking, the forums is pretty much jumbled up, and the existing [Guide] Threads are either incomplete (Lacking important steps), or Unclear (Non-Specific steps).
Perhaps someone could do me a favour by using the template that I have below to help me, and possibly others, to install CM 10.2 on our beast of a phone.
Template:
1. Backup TA and DRMkeys and stuff: http://forum-xda-developers-com/backup
2. Root: http://forum-xda-developers-com/root
3. Recovery : http://forum-xda-developers-com/recovery
4: Unlock Bootloader: http://forum-xda-developers-com/ulbl
5: Install FXP's CM 10.2 :http://forum.xda-developers.com/showthread.php?t=2461286
Something like that would suffice I think, as long as no important steps are missing that would cause me to lose stuff unique to my phone, that cannot be recovered if I didn't back it up.
P.S. My version is 14.1.B.2.257
P.P.S. Thank you in advance.
1. Root
2. Backup TA (VERY IMPORTANT)
3. Install Recovery and unlock the bootloader, or the other way around. Both ways work.
4. Install ROM by following the "guide" that you quoted above.

I'm on 14.1.B.2.257, I believe reverting to the previous version causes data to be lost unless you back it up right. *Sighs* How troublesome.

you will have to back up the data anyways. I think unlocking the bootloader does a factory reset, as well one is needed going from stock to CM if i unforget correctly
I am also wondering about this. I'm currently running firmware .257.
I understand that I need to back up the TA partition first (though I'm not exactly sure on what I will loose if I don't). I also understand that to do this I need to root the stock rom. I understand that in order to root, I'll need to first downgrade to an earlier firmware using flashtool. However, after that I'm not so sure what I need to do. As far as I can see, the only method of gaining root currently is to use vRoot, which is currently under investigation for IMEI mining.
How else can I root the device? I was thinking of maybe using the recovery for locked bootloaders here: http://forum.xda-developers.com/showthread.php?t=2426739
Following by flashing SuperSU from recovery as per usual.
Will this work, keeping the TA partition intact so that I can back it up before flashing CM? Assuming so, would I even need to downgrade from the .257 firmware at all?
Thanks,
i have CWM now so can flash custom roms like i did on other phones right?
what does unlocking the bootloader give me? unless i'm wrong and i have to unlock to flash?
all i've done so far is do a backup is all. (did a TA backup a while back though)

OK, so looking into this further, you already need to have root to be able to flash the "CWM for locked bootloader" rocovery. So as far as I can see, the only way to get root in order to back up the TA partition is to give your IMEI to the Chinese via vRoot?
Thank god the stock rom is so good.

You have to unlock the bootloader to flash custom ROMs. You can flash stock ROMs without unlocking it, but you have to unlock it if you want CM, PAC, PA etc.

really, so what would happen if i tried to flash an aosp rom now? would the system partition essentially be read only?
sorry for the Qs but haven't had a locked bootloader since the htc desire (although the s-off for that one was to remap the partitions to allow more room for data) and the reasons for unlocking don't seem to be the same.

Nothing will happen if you try it now. You can easily unlock the bootloader by going to Sony's Dev site, request your key and use Flashtool to unlock it. It takes a couple of minutes once you have Flashtool and the drivers installed. It's also perfectly safe to unlock it and you will lose your warranty. BUT you can easily relock it again if something happens to your ZU and the warrenty will be back.
Remember to backup your TA before you unlock your bootloader. It contains a lot if device info and your unique DRM keys. Unlocking the bootloader will wipe the system partition, but you will still have root, photos, music etc. (But do a backup of those just in case).

i think that's where i got confused with drivers - unlocking.
i have already done a backup of my TA part so that side of it is ok. i'll leave unlocking until there's a rom i want to try. possibly a complete 4.4 or something.
cheers LM

If you've already backed up your TA, it means that you have the drivers installed, so job done All you have to do is to install Flashtool and get your key from Sony (which you will get on your email straight away). Either way, just ask here if/when you want to unlock it so we can guide you through it (it's very easy though).
ran flashtool but gave me driver errors - missing. unable to install the drivers included (i guess due to windows 8 driver signing)

Boot loop on encrypted Redmi Note 3 Pro Intl Version -- how to backup files?

Hi,
I have a Xiaomi Redmi Note 3 Pro International Version 3GB 32GB.
I never modified this device (no root, unlock etc.).
However, I have enabled the encryption option.
Today, there was another system update which I installed (since I own this device, there was never a problem with these updates).
After installing the update, the device got stuck in a boot loop :crying:
Question: How can I backup my personal data now (e.g. photos)? -- I really would like to have this data (unfortunately, my last backup is a little old).
I assume that, since the device is encrypted and in a boot loop, I cannot wipe the device without losing all my data, correct?
Can I install a boot loader from where I can backup my photos?
Thank you in advance!
Happened to me as well. I had to format it. One thing you could do is unlock it using mi unlocked app. Install twrp via ADB. Twrp will ask for password. Once unencrypted in twrp, you could copy your files onto a SD card quickly. I personally didn't want to go through this hassle and simply wiped data. Lost a ton of data for not backing up sooner.
Thanks for your reply! Sorry that you lost your data...
Can I unlock the phone using the method you described when the phone is already in the boot loop? -- I understood that I have to log in to the Mi account on the phone (which I cannot do at the moment due to the boot loop.
Is there any other way to unlock the device?
Thanks!
It worked -- I could create a backup of all my data.
I described the details in a blog article -- however, this forum unfortunately does not allow me to post the link. You will find it when googling "Irgendwas Verschwurbeltes"

Thank you for sharing the method, here is the link.
I am surprised that fastboot_edl worked on a locked device, but perhaps it depends on a model and MIUI/bootloader version. Anyway, the EDL mode always works with the "test point" or "deep flash cable" methods. I suppose that instead of editing rawprogram0.xml you could just delete userdata.img and the flash would continue with only a minor error and user data intact.

Limit ROOT to ADB?

Hello, until now I avoided to root my device (SGP612 / Stock Marshmallow), because I did not want to risk to lose the drm-keys or do other damage.
Besides that, there some apps, which will not run on rooted devices as netflix (at least I suppose so).
Now working on Tasker and other tools the demand of root is increasing more and more. But still I want to take it restrained and looking for a way to limit the root via ADB. I'm not sure, if that is possible, but I think, that would be a good compromise. Online I found a huge amount of guides and threads "how to root", but all of them, at least it looks like that, ending with an unlocked bootloader, TPRP, SuperSU and so on. I did not read all of them, because that would take years and these guides may also be outdated or even worse incorrect.
Therefor I'm here to ask you about yours assessment.
My main goal would be to:
- Make a full backup
- Protect the DRM-Keys and other irreversible stuff
- No app should be able to detect that the device has been rooted respectively modified on system-level
- Void a reset of the current setup
- Install some apps to system via adb and grant some permissions, uninstall few oem-apps
- Tweak a few settings via adb
Is that possible? And if so, are there some good and simplified guides, which I should read?
Wrong forum. This is for Z3 Compact phone. What you want is https://forum.xda-developers.com/z3-tablet-compact
You can root the phone without unlocking the bootloader, so I would assume that you can do the same with the tablet. You have to flash with an older ROM/kernel first, though, but it is doable.

I will ask the moderation to move my thread, thanks for the hint.
That sounds complicated to flash an older ROM, especially if no suitable instructions are known to me.
BTW. I prefer to stay at stock.
I am pretty sure you posted in the right forum. Everything you mention is possible, except making a full backup. I wouldn't know how without root or twrp. You can backup your TA partition with a special tool to save your drm keys. It uses the 'dirty cow' exploit so you may need to downgrade first (which wipes your data).
I think root via ADB requires a custom rom. You need to unlock your bootloader, which wipes all data. Alternatively, you can root your device with Magisk. It can hide itself from detection for a set of apps that you select.

The thread has been moved by now, so that should be ok.
But still, I do not want any custom-rom. My experience with such on other devices in the past was very frustrating and a waste of time. Had always stability issues on driver-level and other misbehavior. On one samsung device I tested around ten or more roms and all of them was quite ****ty...
And until now it sounds like, I need to install a custom before I even can start to make backups and such. But I want a backup of the status quo, to which I could always rollback, if things gets ugly.
I like the current stock, is a good and stable base, a few tweaks and it would be perfect for me. Of course, I did not test any customs on my current device to be able to make some substantiated conclusion on that but I'm to distrustful to follow this path, especially not when there is no way back.
I miss any imagination what is possible and what is not, or what effect a particular measure entails. Therefor I can't estimate the accuracy of any guide and there are hundreds of them out there, and it looks like the approach is sometimes different. I started reading some of them, but stopped it because I could not retrace the content.
Can you recommend a good guide, which could work out for me and whats the name of the tool to backup the drm-keys? Thanks...
Check here for the TA backup https://forum.xda-developers.com/cr...rsal-dirtycow-based-ta-backup-t3514236/page47
I am very happy with this rom, the developer recently issued a Pie alpha (which I haven't tried yet)
https://forum.xda-developers.com/z3...m-aicp-android-ice-cold-project-o8-1-t3731197
There's a guide for rooting + recovery @ https://forum.xda-developers.com/z3...to-rooted-lollipop-locked-bootloader-t3083980
Be sure you follow the instructions very carefully, since you are flashing (the system partition) with the ROM from a Z3 phone.
The process is similar to the Z3 phones:
- flash to an older ROM
- root
- install custom recovery
- using custom recovery, flash with a prerooted, updated ROM
No need to unlock bootloader and no need for custom ROMs.
Asides from that, I don't know how to do the rest of the stuff in your list.
(I'm debating on getting a used Z3t, which is why I'm researching root possibilities .)

Alright I've received the email to unlock the bootloader now I have some questions before using it..

Alright, I've received the email as the title implies but here are the questions I have before I proceed into the whole process
Is there a way to backup the stock image without TWRP? if so how do you get the stock image backed up if it's impossible how to back up the stock bootlover/recovery before installing TWRP if I were to get rid of TWRP one day?
also is it possible to just root the system without flashing anything to avoid data loss? this would be the preferred option actually, thanks! (Using the be2028 t-mobile version, if there's a premade backup that'll be cool too.)

I am just getting back to messing around with phones after about 5 years. So many things have changed and I am trying to get answers here as well.
I used TWRP and Magisk to root my phone. Installing TWRP will not wipe your data as it is flashed to a different partition but to install TWRP you have to unlock the bootloader and that will wipe your userdata. And no, I don't believe there is any possibility of rooting without unlocking the bootloader. If you decide you want to go back to stock, there are stock roms available and you can re-lock the bootloader on the N10 so you should be able to set it back to just like it was when you first bought it. I say should because I have never done it, just read that it can be done when I unlocked and flashed mine.
I wish I could be of more help but so many things have changed in the years since I've been away from doing this stuff I feel like a total noob again.

No I do not believe there's a way to gain root without flashing anything. There's no need to backup anything you can always use the MSM download tool to restore your device. https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4204445/ You should be able to find most of the stock imgs on here already if you'd really need to flash back. I'm no expert either, just my experience with this phone in particular has been pretty straightforward. I never backed up anything lol.
Twrp is iffy i made a backup I'll never use, check out the post about flashing international rom to tmo and metro devices, that's my backup. Also you can run 11.0.3/2 firmware and boot 11 gsi's the post about lir rom has the info. Flash the product_gsi.img referenced there, I have never deleted my product partition and I only leave oos ten installed long enough to take ota's. There are more roms in the source forge page referenced with lir rom post. Flash magisk via recovery, either side load or twrp, pay attention that it flashes partition sda14(super image) or wifi breaks.
