Hello everybody!
I am fairly new to the modding world of android, all I know is that you need an unlocked bootloader to install a custom recovery to then root or install a custom rom. I have a specific set of questions to upgrading my phone software (Lenovo P2a42 on android 7.0):
1) Do you do anything after waiting for 14 days on the OEM unlock screen? Does it auto reset the phone, will a pop up appear, etc? Does it automatically unlock the bootloader or do I need to do adb fastboot oem unlock to finalize unlock?
2) Is there a complete all-in-one guide to installing a custom rom (bootloader unlock, TWRP, flashing, dealing with problems (encryption, fingerprint, wifi, safetynet, etc), etc) from scratch (stock rom)?
3) Is there a way I can back everything up (and recover of course, stock image and recovery, and anything else I might need to go back to factory defaults) in case I screw anything up?
4) What is the least buggiest / most popular / most supported android pie rom available for my phone (Lenovo P2a42)?
5) Anything I should know before proceeding? For example, I know it voids warranty and official support, potentially loosing google playstore, but is there anything else I should know?
I might require further assistance, as I have absolutely no experience. But hey, I gotta start somewhere right?
Thank you for your time.
1.on day 14 the option to unlock is shown in the settings menu.
2. I used this
https://forum.xda-developers.com/lenovo-p2/development/lenovo-p2-root-tool-t3800838
3.TWRP has a backup option in the Recovery menu.
Read the TWRP threads to understand better.
4.for me I like 8.1
https://forum.xda-developers.com/lenovo-p2/development/rom-aospextended-rom-v5-4-t3774641
But am currently using 9.0
https://forum.xda-developers.com/lenovo-p2/development/rom-arrowos-9-x-t3862818
5.anything else to know?
Just make sure you read the thread for whichever ROM you use.
And then enjoy

The 8.1 rom you provided is AOSPExtended, is there a 9.0 version of it for the P2a42?
Thank you for your time.

Hello,
I currently have a XZ2 compact H8324 rooted
Build number : 52.0.A.3.126
I rooted it some years ago and to be honest I don't remember well what I used to do it. I just remember DRM are safe.
The bootloader is unlocked if I remember well (warning message at boot)
Could someone please tell me how to update to latest Android version still rooted ?
I don't care about format it, but I would like it to work as usual (camera stuff) with root.
Is there some kind of precautions ? tools ?
Thank you.
Edit : downloading 52.1.A..3.49 with XperiFirm currently
Xperifirm might work. You can also try Emma (Sony's official flashing tool) which is easier to use but will wipe your device and uninstall any custom recovery you have installed. Your bootloader will remain ulocked, and your DRM keys intact, so you can always reinstall custom recovery after that.
You can also install LineageOS. They have an official 17.1 (Android 10) build for the XZ2 Compact, so it should be very stable and have minimal issues. I'd recommend installing LineageOS after flashing the latest firmware with Xperifirm/Emma because the stock ROM doesn't play nice if you have root or TWRP installed.
Thanks @dankcuddlybear for your answer.
I don't care about custom recovery and data as long as I'm able to flash back custom recovery and root after flash.
If your current Pie variant is fast, stable and is fulfilling its mission, be happy and leave it be.
Q is using cpu cycle wasting scope storage and is a downgrade in many ways from Pie.
Being rooted means you could (?) overcome many of these limitations but how much is your time worth?
Android 10,11(Apple) woke, go broke

Not good. Pie should be rock solid stable.
It sounds like it's fixing to crash and burn.
Look at the launcher and other 3rd party apps you're using. That load maybe corrupted or the original firmware was flawed.
Hi there fellow Moto G5 users. I've been fiddling some time now with the 14.1 version and I want to try out the new 17 version with nightly's. Normally I've have no problems with upgrading or downgrading rom's for my devices, but since newer versions are now 64-bit it's throwing me off.
Since there are so many topics around with tips and procedures I'm a bit confused how to get started to migrate/change to LineageOS 17.
So could anybody help me on how to upgrade to LineageOS 17? As far as I know my phone has: a unlocked bootloader, TWRP with 64-bit support and LineageOS 14.1. What would the first step for me do?
As far as I understand it would be something like this:
(0. Backup up everything + written down both imei's) - done this in advance
1. Lock the bootloader again (whilst LineageOS 14.1 is still installed?)
2. Erase everything (with commands)
3. Flash an official Moto G EU rom (with commands)
4. Update it using OTA to the latest supported version to get a 64-bit rom/kernel/bootloader installed
5. Unlock bootloader again
6. Flash custom recovery again
7. Flash LineageOS 17?
That is what I'm thinking for me to do, is it correct? Or do I miss some stuff?
Any help will be appreciated.
Never lock the bootloader once you have unlocked it - if anything goes wrong in the future you will never be able to fix it without specialist hardware or a motherboard replacement
There is no need to lock the bootloader to change roms
See my post below that is basically answering the same question for full instructions on how to upgrade
Basically update stock firmware to latest retail then format data with latest offical twrp, wipe system data cache & flash rom
[SOLVED] LineageOS stuck at first boot (moto G5 xt1676)
Hello everyone, I just got a Moto G5 (on a refurbishment store) that works perfectly fine with stock OS. My goal is to install lineageOS on it. I managed easily to : - unlock bootloader - install TWRP (3.5.2_9.0) or the lineageOS recovery -...

Thanks for the warning, I will try your instructions and see what I can manage. Will post any updates.
I've just updated the rom to 8.1 official. Thanks for the help. @TheFixItMan
And now i'm on Lineage 18.1/Android 11 working great so far.
Hi everyone,
I would like to know if it is safe to unlock bootloader and flash a custom ROM under MIU 13.0.3 SKHEUXM ?
I've seen people having bugs, hence why I'm asking if anyone has given this a try ?
Furthermore, I was going to do this update in order for the firmware to be updated then switch to a custom ROM, but I could go for custom ROM first then flash the newest firmware (even if I'm more confident on the first option which should work out of the box, and preserve warranty in case something goes wrong during flashing firmware, always gotta keep fingers crossed).
Thanks for any help on this matter.
If you updated to the latest ROM, your firmware is updated along with it, there's no need to flash the firmware again seperately. Flash the ROM of your choosing, Magisk if you absolutely need it, and enjoy. Most ROMs these days also pass SafetyNet if you do not root your phone.

It's not very safe, you need to be careful.
Make sure your PC wouldn't crash or that your USB connection may be unstable.
Take your time in setting everything up and reading up some resources on the internet.
If the Flash-process aborts for whatever reason, do not reboot phone. Your phone may not be able to reboot back into Fastboot and turn black.
As for good resources of information, I recommend the YouTube Channel "Munchy". He covers Xiaomi Flashing very well. You can trust him.
https://www.youtube.com/channel/UCDSfvwvAsKE4Nrosu7bTbJw
You might also want to use a Custom ROM with passing SafetyNet, or to use Magisk Root. If SafetyNet fails, you can't use some apps.
I personally use Xiaomi.eu Weekly Android 12 with Magisk Root + SafetyNet Fix Module. No bugs, I'm happy
My only wish was that I had Over-The-Air updates. With most Custom ROMs, you unfortunately still have to download & flash the ZIP-file manually in TWRP Recovery.
Hi, a have recently purchased the XZ2 Compact single Sim model, it should arrive later this week. While waiting, I would appreciate everyone's opinion on which stock firmware version is best in terms of performance and battery life:
• Android 8 Oreo
• Android 9 Pie
• Android 10
Or if you guys haven't found a any difference, between firmware versions at all, then please comment below !
Thanks in advance.

Thanks for your suggestion, I just meant stock, without rooting, or installing any mods. Like has Sony made it worse with a9/a10 official update, or is there no major performance loss when upgrading ?

I have never used stock as-is, because of Sony bloatware, restrictions, etc, but I typically prefer stock UI over most custom ROM UIs, so if I can get eXistenZ, I will always go with it. @niaboc79 has been the master of Sony roms going back to at least 4.4. Between UI customization and under the hood type stuff, there's no better option I have found. With root and eXistenZ, the whole firmware is at your control...
If you're only interested in straight-stock vs. custom ROM, then custom ROM is by far better, but not sure why you would limit yourself to straight stock if that's the case, because you have to unlock bootloader and root to use custom ROM. The only advantage of straight stock is official support/security, which is arguably n/a in this case, since the last official update was 2 years ago...

Hi, ah yes, I also prefer rooting and custom roms, but there's chance the device won't be in unlocked, because I ordered it from Aliexpress, and it's the Japanese Docomo version. Anyway I also heard that some features and good photo quality, get lost when unlocking ? Is there a work around if the DRM keys get lost ?

I don't think there's any such thing for this phone. Some have found a way to dump ta, but not to restore it, so not much use...
I upgraded to 10 to start with, then unlocked bl, etc. I think that's the best way. There's much discussion in the forums about camera function and drm in regards to 8 and 9, (ask @MartinX3 or @Pandemic), and seems like there may be different things you can do...
I'm not so hung up on the finer aspects of camera functionality. I think the difference is pretty subtle. Camera is good for me, (probably better on stock with unlocked bl than on custom/AOSP).

Not sure what you mean by kernel brand, but you know if flashed properly because the ui and options will be drastically different with eXistenZ compared to stock. If everything's the same, then it's not flashed.

Yes i just realized the flash didn't went through. im experiencing many issues. Firstly twrp is not flashing anything always some error of storage access or something. then i try to flash on los recovery, and it works for lineage perfect flash, but for existenz stock zip it flashes everything no errors but doesn't change anything on the stock rom (.618 clean install) i can't seem to figure it out...

I did some research and from what is logged on existenz page it includes nothing more than UI customizations? Am i missing something. How can this stock patch be the best for you if it only does UI changes..?

- Which version of TWRP? Make sure you are using the right one. Should be this one - https://forum.xda-developers.com/xperia-xz2/development/recovery-twrp-3-3-1-0-t4074305
- Did you follow this, (from eXistenZ thread):
Flash latest android 10 firmware with Newflasher and boot it once.
Reboot in bootloader mode with adb (adb reboot boolloader) and boot TWRP (see TWRP thread for instructions).
Inside TWRP, go in settings and uncheck unmount system before flashing.
Mount system partition and Flash eXistenZ Quidim cleaner.
Boot once, it shouldn't reach pin code screen, reboot in bootloader mode with adb.
Boot TWRP, mount system partition and flash the rom.
Flash Magisk.
(e.g. - make sure to boot once before flashing, use adb for bootloader mode, check system in TWRP, etc...)

I used 3.4.00 twrp, maybe should try 3.3.10. Also i flashed .618 which is 10 though not the latest but it should be the same thing.
The rom seems to flash, because i get the existenz custom settings on phone settings, idk if that is all it does.
