4.4.4 to 5.1.1

Hi folks,
can i go straight to this? my tab is rooted. IF i was to unroot then download the full rom from google, and flash the system, recovery and boot, would this be ok, what i mean is, it doesnt have to be iterative to the latest version does it?

What I did was the flash the bootloader 4.05 and Scrosler's Stock Rooted Busybox 5.1.1 ROM http://forum.xda-developers.com/nexus-7-2013/development/rom-stock-rooted-5-1-1-lmy47v-root-t3098137. Follow his instructions or if you want to dirty flash, use TWRP to first wipe the 2 caches, flash the bootloader and then ROM, wipe caches again and boot to system. The first boot is very long.

You need to flash the bootloader as well since it got updated.
No need to unroot, you're flashing the system image..
Bootloader boot and system will do it, I'd recommend a clean install though. Flash all partitions or run flashall file letting it wipe the tablet.

ok thanks folks. didnt realise the bootloader had to be done too. I guess this also applies to my N5 when im updating that too?
SO .... if i was making instructions to flash my devices for future updates, would the following suffice?
dont unroot
dont remove TWRP
fastboot flash bootloader bootloader-hammerhead-hxxxxxxxx.img
fastboot flash radio radio-hammerhead-xxxxxxxxxxxxxxxxxxx.img (do i need to even do this?)
fastboot flash boot boot.img
fastboot flash system system.img
boot to recovery and wipe dalvik cache

scrosler's ROM is standard 5.1.1. The beauty of it is that your phone will be rooted and busybox installed (with a trim). Just use TWRP to wipe whatever partitons you want (the 2 caches and also data if you want a clean install), then add bootloader and then ROM zips to the queue. Install them, then wipe the 2 caches again and boot to system. You might have to install SuperSu again from Play Store but you will be rooted.
It couldn't be simpler

Updating to Android O / Nandroid Restore back to Android N?

Used the search, used google, couldn't find any concrete answers
I am on Android N - unlocked bootloader - rooted via magisk, One Plus 3.
Could I do the following?
use TWRP to make a Nandroid Backup (System+Data+Boot) of my current set-up
then, manually flash (using twrp) Android O
find out I don't particularly like it
Go back to TWRP and Nandroid Restore back to Android N, as if no update ever happened
Or will there be issues?
Thanks

I do that with freedomos. 2.17(N)>3.1(O)>2.17. I restore nandroid and reflash rom

Should have mentioned I'm using stock rom.
So I'd restore the nandroid via twrp, and I should be good to go?

There won't be any issue. You are alright with the procedure. Just make sure you use the correct twrp recovery for oreo coz if you use the non compatible recovery then you won't be able to boot into recovery once the oreo is flashed and you are forced to go with the stock recovery
Process I followed when I tried oreo last week
Take nandroid of all options available except system image. (system, data, bootloader, firmware, efs, etc.) on nougat twrp.
Do factory reset(wipe everything except internal storage) then flash oreo twrp image. Perform reboot. (no OS warning on reboot option screen will appear) just ignore it. It will boot to recovery even without the OS.
Once booted back to new recovery(oreo twrp)
Flash oreo stock zip and again flash oreo twrp image and reboot to recovery(this time the device will get stuck with a black screen and white LED). Don't panic, just force reboot the device and go to recovery again to flash magisk/supersu. Reboot to OS
Enjoy oreo
To go back to nougat
Reboot to recovery.
Perform factory reset as mentioned above.
Restore everything except bootloader, cache and dalvik cache
Flash nougat twrp recovery. Reboot to system.
Happy flashing.
Edit : use blu sparks recovery for nougat backup.

Go to twrp - advanced - file manager - go to root folder - data - system - and delete files with .key extension. There will be 2 files delete both and reboot.

This should not have happened, anyways delete all those files which I've highlighted in the image below. This will reset the lock settings.

Oh sorry I forgot to attach the file. Here it is.

Hi, OP here. Thanks for this guide.
Unfortunately, it did not work out for me.
Take nandroid of all options available except system image. (system, data, bootloader, firmware, efs, etc.) on nougat twrp.
Done
Do factory reset(wipe everything except internal storage)
Wiped fine although I got an error of not being able to wipe 'USB-OTG' or whatever it's called. I ignored it and moved on.
then flash oreo twrp image.
I googled oreo twrp image and got an img file with filename "TWRP-Oreo-OnePlus-3-3T". When I installed the img, it asked the options to choose Boot, System, or Recovery - so I chose System.
Then I rebooted and went back to recovery.
Flash oreo stock zip
flash oreo twrp image
Done
reboot to recovery(this time the device will get stuck with a black screen and white LED). Don't panic, just force reboot the device and go to recovery again to flash magisk/supersu.
This is where it ends. I get stuck at the OnePlus loading screen and forced reboot into twrp and flashed magisk. Once I boot up the OS, I get stuck at the OnePlus logo and that's it.
I actually re-did ALL of the steps again (in case I made a mistake) and still, the same issue. No progression.
Once I gave up on Oreo, I decided to go restore my nandroid
Reboot to recovery. Perform factory reset as mentioned above.
Wiped
Restore everything except bootloader, cache and dalvik cache
Here's the issue:
I press Restore (I uncheck both bootloader and cache, but there's no option for a specific dalvik cache- unless I'm not looking hard enough?) and I get the 255 Error.
Flash nougat twrp recovery. Reboot to system.
I tried to ignore that error and flash the twrp recovery.
Rebooted and it took me to fastboot. Regardless of I keep trying to reboot system it won't work.
I actually made two separate nandroid backups (the same 'everything except system image' as you've described) in case one of the backups was corrupted. Both backups ended up with the same error.
I got too tired of all these errors and just found a stock recovery and ROM and flashed it back. Now, all my apps and settings are gone. To be honest, I just want my phone back to where it was with Nougat.
Can anyone assist me?

@maxs8007, Like I said I did that already but nope still same issue. It wouldn't let me do matter what I did.

Buddy from my experience the whole thing too finicky and am thinking just factory reset and stick with stock rom. I wasted so much time already. Everytime I get different error, probably recoveries still not fully compatible with Oreo.

Could you please tell me what error you get on the lock screen? Could you post an image so that I can get a better idea of what's happening with your device? Also could you please confirm which files have you deleted? This time you need to delete 5 files which are related to lock screen setting and those are the only files responsible for lock settings on the device. I'm somewhat confused because I never ran into such issue while I did the oreo thing
If you have decided to flash stock then just make a backup of data partition so that you won't loose your data and you can easily restore it via twrp.

I read the entire post and here what I've to say. The above quoted steps is where you went wrong. The recovery needs to to be flashed as a recovery and not as system.
In your case the nougat recovery was never replaced with the oreo recovery because you flashed it as a system. This is where it went wrong. Sorry for the dalvik cache and USB - otg, I didn't mentioned about them. Those are the least important points in flashing though I should have mentioned that already
The next thing you mentioned is you went back to recovery which at that moment was nougat recovery and not oreo recovery. I'll link the modded recovery I used for oreo below
The next thing you did is you flashed oreo zip and again flashed the oreo recovery but as you flashed the recovery as system, the oreo stock rom was automatically replaced with recovery because you flashed it as system and the device didn't boot because there was no android OS to boot up
You got stuck on oneplus boot up screen. (this was going to happen because of the same flashing error at your end).
You were unable to boot back to nougat as well because of the same issue.. Never flash the recovery as system. This won't let you boot the device.
To restore your nandroid backup just follow the steps below
As you confirmed you booted to stock rom with a stock recovery.
Flash nougat twrp via fastboot
Boot back to the twrp recovery and restore the nandroid backup and you are good to go

I'll make a video in my free time to help you guys with the steps that I've followed to flash oreo rom and how i came back to nougat successfully.

Hello @maxs8007
Sorry I didn't have any screen shots of the prompt and finally I was fed up with the whole process and had to switch back to oreo stock rom.
Login prompt I was referring to was standard pin required load android. Black background with only pin entry.
BTW I tried blu twrp recovery oreo version and nougat version.
What's interesting is, after several failed attempts it said I got 10 more tries before phone wiped out but after 10 attempts it started counting backwards from zero, - 1,-2 etc., finally I had to flash stock recovery via fastboot and selected forgot password option which reset my phone.
BTW I have deleted all those files from data/system I found another thread but no dice.
Thank you for trying to help us all.

@maxs8007 followed your steps. Booted to oreo, didn't felt as stable as nougat then booted back to nougat. You saved me. Thanks.

I'm sorry that I was unable to help you. The thing is I never used the pin prompt to load android because I reboot too often to flash things via recovery and its too much of a hassle to enter the pin everytime the device is booted and I think it's too much to a security for a android device when there's already a lock screen present once booted to secure the device.
Please don't put the pin entry to load android next time if you flash stuff regularly. It will save you the hassle of going back to stock rom and recovery when something like this ever happens again. The files which I told you to delete in the image I posted above remove the lock screen protection completely
The login pin at the boot to load android was implemented to avoid unauthorized access to the device in case it gets stolen or lost.

Frankly no clue why deleting those files didn't reset my pins and I even deleted gatekeeper files too.
Maybe these are lock screen key files and android boot prompt stored somewhere else. Not sure though.

Seeking a better understanding

Hey all,
I'm trying to better understand what I'm doing with my phone here. Currently I have my OP3 rooted (aka unlocked bootloader, correct?) and on 8.0.0.
1. If I wanted to keep it rooted and reinstall the OS, is this as simple as downloading whichever ROM I want, copying it to my phone's internal storage, and flashing it in recovery using TWRP?
2. Is stock recovery (recovery_OP3.img on the oneplus.net website) the same part of the software as TWRP? As in the stock recovery is locked bootloader and TWRP is unlocked bootloader?
3. I've been searching for the most recent root guide, can I get a recommendation? I've read that SuperSU is not the thing to use any longer, but rather Magisk. Correct?
4. What is boot.img?
Thanks all

1. If you switch roms, always do a clean install (wipe all partitions) . If you want to get rid off all the mods wipe system and flash the same rom + gapps + root. You won't loose data since you are only modifying the system partition.
2. Stock recovery by Oneplus is as if says stock, you littery can't do anything with it apart from upgrading your OOS, wiping cache partitions and doing a factory reset. I do recommend the TWRP provided by Bluspark since that seems to be the only one I tried without any issues whatsoever.
3. Magisk is the new root method in my opinion, it supports Magisk modules which simply are mods that can be installed and removed with a single click (reboot required tho). You can compare it to xposed but very limited when compared.
4. Boot.img is your kernel, never flash standalone img files apart from TWRP since the kernel modifies more the only the boot img. Always flash the full zip.

HELP! Phone only boots into recovery after fresh install

I have now tried to install the latest RR and Omnirom builds and the problem remains the same.
I've been very particular about wiping data before the installs.
Here is what I have done,
Performed data wipe by typing "yes" when requested. Used advance wipe to wipe everything.
Installed Rom, Stock Gapps and Magisk zip files.
Wiped Cache.
Reboot
The phone will not boot and only returns to recovery.
Can anyone help?

Here is my TWRP log if this helps - https://pastebin.com/ghpXkt3t

Not sure if this is relevant, but every time I try to flash a ROM it always fails on the first attempts and needs a second try to succeed.

If you only get to the mi logo and not the ROM boot screen then format data "yes 3-4 times in a row.
If that doesn't work then wipe the system and data and retry

I was only getting the Mi logo, so I did the format data 4 times in a row and rebooted.
I then saw the Omnirom logo for the first time!
unfortunately 2 seconds later I'm back in TWRP.

I have now tried for the 5th time to perform a fresh install.
Formatting data multiple times, wiping system and data multiple times.
The result is the same.
I see a flicker of the Omnirom logo and I get booted back into recovery.

Please try this:
1. Wipe: Dalvik / Art Cache; System; Data; Cache;
2. Go back to main TWRP screen and install the rom, install Google Apps, install "addonsu-15.1-arm64-signed.zip" (in case of Lineage) or the latest Magisk (in case of other rom)
3. Wipe Cache
4. Reboot
If this doesn't work and the device restarts in twrp, then pls download the twrp flashable Xiaomi rom from here: http://en.miui.com/download-334.html
1. Wipe: Dalvik / Art Cache; System; Data; Cache
2. Go back to main twrp screen and install the Xiaomi rom. Do not reboot.
3. Go back to main twrp screen and Wipe: Dalvik / Art Cache; System; Data; Cache
4. Go back to main twrp screen and install the rom (Lineage or OMNI or RR), install Google Apps, install "addonsu-15.1-arm64-signed.zip" (in case of Lineage) or the latest Magisk (in case of other rom)
5. Wipe Cache
6. Reboot
I had the same problem and this method worked for me, maybe it will work for you too. :fingers-crossed:
If it doesn't then maybe you have to start from zero and flash the original Xiaomi rom in fastboot mode (rom here: http://en.miui.com/a-234.html) via MIUI ROM Flashing Tool, unlock bootloader (bootloader might relock), flash twrp and then flash new custom rom.

No idea what happened but I have the same issue atm.
I was running a recent Omnirom for a few weeks. System got unstable, so decided to flash the newest version. Got me stuck in a bootloop. I tried everything, short of relocking and unlocking the bootloader.
- Full wipe, including storage
- Reflash Global Dev through TWRP.
- Flash stock Global Dev over flashboot
- Flash Omni, wipe, flash omni again.
All the same. Global Dev runs, all AOSP roms just go into bootloop. No idea what went wrong, I've flashed tens of custom roms over the past months without issues.

Then maybe the right solution to get out of bootloops would be to start from zero and flash the original Xiaomi rom in fastboot mode (rom here: http://en.miui.com/a-234.html) via MIUI ROM Flashing Tool, unlock bootloader (as bootloader will relock), flash twrp, do a full wipe and then flash new custom rom.

I have reflashed the original Xiaomi ROM (running it atm ) using the official Xiaomi Flash Tool.
I just did not relock my bootloader doing that (there's an option to leave it unlocked). Will relocking and then unlocking the bootloader really make a difference?

Not really. You ev. save yourself a waiting time of 72h....

Not sure what happened. I set up MIUI completely. Then, getting frustrated after using it for 10 minutes, decided to try one more time. Same thing.
1) Fastboot flash TWRP.
2) Wipe
3) Flash Rom
4) Flash GAPPS
Worked this time. No idea what went wrong the first 4 times. Only difference is that I went through the trouble to set up the entire phone this last time before trying again.
Anyhoo, so if anyone has the same issue. Set up phone in MIUI, only then wipe/flash

I got mine working by not installing Magisk. I just flashed Omnirom and GApps and it worked.
After setting up my phone I have since rebooted into recovery and installed Magisk and it works.

Can't system boot after install TWRP, Lazy Magisk on MIX M2S
Hello,
I have this problem, the phone does not boot after TWRP, Lazyflasher and Magisk being installed all fine.
I have re-installed the official ROM on my Xiaomi MI MIX 2S, then TWRP is fine too, then Lazy and Magisk fine.
When I reboot, it is stocked on MI logo whatever I do.
I have tried most of the advise posted but still stocked.
I restarted from scratch, installing again the official ROM, then fastboot flash recovery twrp, then lazy and Magisk, but still stocked on MI.
Thanks a lot in advance

Did you wipe system by any chance.. If you did you need to flash miui again with fastboot.. Or boot into fastboot and type this command 'fastboot format userdata' and press enter. You are facing this issue because of encryption

Gratitude for your reply. What do you mean by "wipe system". I installed the rom and then TWRP etc...
I flashed the ROM again and went into bootloader
I typed "fastboot format userdata" and the system replied:
"/usr/local/bin/mke2fs failed with status 1
mke2fs failed: 1
error: Cannot generate image for userdata
Can you advise.
Thanks a LOT

Did you use the correct rom ? Mi mix 2 or mi mix 2s?

NO, I followed the usual process with ADB tools.
However, I have no boot "stuck at MI logo (bootloop)" problem when I flash the ROM.
It happens only when use TWRP and flash Magisk and Lazy.
Then, when I restart it got stuck at MI Logo.
Do you suggest I try to flash with MI logo (I don't have a PC though).
If so, should I just flash the ROM and then, what about TWRP, should I use MI flash or ADB?
I just want to make sure that the problem is with the ROM instal?
Thanks a LOT

Flash twrp via fastboot.
Boot to twrp via
Fastboot boot twrp.img
Replace "twrp" with the file name of your twrp.
Once twrp booted, go into reboot menu. And reboot to recovery again. That will make your phone boot again into twrp, but this time with more rights.
Go into wipe. Advanced wipe
Change data partition file system to ext4.
Reboot again into twrp via the reboot menu ,just like before.
Now go into wipe again, and format system,data,dalvik and cache.
Flash your rom.
Flash gapps (if not otherwise stated by ROM thread)
Flash Magisk (optional, if you want root)
Wipe dalvik and cache.
Reboot. And enjoy

We only have one bootloader.
We have different firmwares though like nougat and marshmallow.
You will need Firmwares S244 for nougat ROMs.
That firmware must be flashed through ota. Stockrom-feature. Simply using twrp does not count as doing otas.
Basic starter things: Have Firmware S244 or S251 installed through stock ota feature.
Then use my earlier stated instructions.

Thx alot it worked & no problems
