[D5503] Lollipop 5.1.1 goes AICP 13.1 Oreo 8.1 /// Beginners Link Collection

Hello hello,
this will be my "live" thread of bringing AICP 13.1 to my xperia z1c, I found some Guide's that I will follow and I will share with you all the links and knowledge I gained as a newbie that I used to understand and fix my problems on the way.
Maybe this will help you, too.
Main Tutorial: LINK
Target of all this: LINK
My Device:
Sony XPERIA Z1C, 14.6.A.1.236 , Lollipop 5.1.1
My best hint: read carefully, take your time to understand what you're trying to do and do your own research!
Hopefully you will get a aicp custom rom out of it.
_____________________________________________
_____________________________________________
General information: Android 5.1.1 cannot be rooted due to its high security standards, therefore we will downgrade to a lower security stock rom and create root access there. Root access will be needed as well as an unlocked bootloader to install real recovery (TWRP) which is the tool to flash custom roms like aicp. But the aicp custom rom will not have a good working camera, don't ask me why, but the camera seems to be a really difficult thing from the point of developer's view, let's accept this. Aside of that disadvantage, this custom rom is a very nice software and it makes my z1c kind of new. I don't use my camera anyway often at all.
During all this flashing thing I had a very big ??? while implementing real recovery. I was able to flash the .236.ftf but not the openbootloader.ftf as described in section 5 in the main tutorial. The result was twrp boot failed.
Error description:
flash .236.ftf works
flash openbootloader fails
flash twrp works
boot twrp fails
boot stock rom works
My solution:
I restarted from scratch and finally with the kind of messed up secquenceI got it:
flash .236.ftf works
flash openbootloader fails
flash twrp works
boot twrp fails
flash openbootloader works
flash twrp works
boot twrp works
UPDATE 06.12.2018 as a solution for REAL RECOVERY with working camera <<< RECOMMENDED
0. boot into rom works
1. flash openbootloader works
2. boot into rom works
3. flash .236.ftf works
4. boot into rom & check camera works
3. flash twrp ( business as usal ) works
4. boot twrp ( First boot is damn important, don't miss it! Press Vol- & Power, wait for vibration, release Power & keep Vol- until twrp boots up ) works
5. full wipe, flash aicp-rom, flash gapps, flash magisk-root, boot system works
6. enjoy Oreo 8.1 & camera check !!! works !!!
This routine worked straight forward for me where I started from scratch with my second device.
Flashing aicp was pretty easy, good to know for flashing the rom was full wipe = advanced wipe and select everything except of micro sd
To complete my aicp 13.1 Oreo 8.1 device the camera problem has to be fixed ( Saving the taken picture fails, display goes into freeze, no chance to solve this with camera mods, camera apps )
But @lm089 gave me the right hint, and finally this was my solution! Thanks again @lm089!!
Have fun with your new >> SONY XPERIA Z1 COMPACT <<
How to update TWRP
1. Turn Off your device
2. Start device in fastboot mode by connecting via usb cable to your pc and press Vol- until blue led tuns on
3. use fastboot flash recovery twrp.img to flash it
4. boot twrp ( This first boot is damn important, don't miss it! Press Vol- & Power, wait for vibration, release Power & keep Vol- until twrp boots up ) works
How to update to aicp 14.0 pie 9.0
starting with the running and latest aicp 13.1 oreo 8.1 rom above I just followed the Instructions here. As a specialty I had to install the Magisk Manager App manually into the rom to get root. Downloading supersu.apk from www.supersuroot.org works fine as well.
Your fastboot connection doesnt work for some reason though u had this workin fine in the past? maybe u had a windows update. install your drivers again.

THANKS A LOT TO @colaigor for his [BEGINNERS GUIDE]

Ok. So i dont have much time now but i can give some short directions.
1. Get unlock codes from sony for bootloader unlock
2. Instal adb and fastboot at your system(PC)
3. Instal z1c drivers
4. Instal flashtool
5. Unlock bootloader,root,flash recovery(search forum for "real recovery" ),flash root solution
6. Flash wanted rom,gaps
P.P. On second thought u dont need flashtool. All can be done with adb and fastboot commands from terminal

There is one thing I don't understand:
what is the difference between FLASHING REAL RECOVERY and FLASHING FAKE RECOVERY?
What I read is, that in both cases I get TWRP but on different partitions (real = Recovery Partition, fake = Boot partition) but do I need both or do I choose just on of them?

Real recovery have its own partition(after that update to bootloader). Custom recovery dont have that and its stored somewhere else(FOTA,onetime boot image , etc). Choose real recovery. New stuff works good with it.

Ok thank you :good:

solved, I skipped step 5.2, flashing the .236.ftf in advance
but how can I start TWRP?
doesnt work with POWER + Vol-, vibrate & release power
I tried to flash the following recovery solution using this command:
smartphone in fastboot mode (blue LED enabled)
fastboot flash recovery recovery.img
TWRP from step 5.1 of the GUIDE
TWRP 3.0.2
My formerly flashed .236.ftf rom works fine, but I cant start TWRP the device goes directly to my rom

Thats where I'm stuck right now, any ideas how to fix?

okay got it, basically i do not know what the problem is but:
after BLU
flash .236 :good:
flash openbootloader
flash twrp :good:
--> failed to install openbootloader and probably thus twrp failed
solution: I skipped to flash .236 as recommended by the author of the GUIDE (step 5.2)
flash open bootloader :good:
flash twrp :good:
--> failed to start twrp, though it was installed successfully
flash .236 :good:
flash openbootloader (failed again, but it's already on the device and I guess I could have skipped this here)
flash twrp :good:
first boot of twrp is successful :good:
And basically the author explained it in his text, FIRST INSTALL OPEN BOOTLOADER BEFORE WRITING STH TO RECOVERY PARTITION

I think you should use Aicp 14 pie instead of 13.1 Oreo
I feel Aicp 14 PIE is very stable and flash port camera stock this link https://forum.xda-developers.com/crossdevice-dev/sony-themes-apps/port-stock-camera-nougat-roms- t3628791

Nice thread, thank you! Wish I had that when I started rooting and flashing

@lm089 Haha it's quite some work to get into it, right? I just saw that we are running on the same device & custom rom, how did you solve the issue with the not working camera? I'm still reading stuff about some mod, but I'm curious and open for tested solutions on z1c
best, dj

Had this situation twice with 2 different oreo ROMs. Both times I solved it following a rather strange sounding suggestion I found on the AICP 13.1 discussion thread. The basic idea is to go back to a stock Sony ROM. Boot into it and make sure the camera is working which for me was the case both times. Then - if necessary - re-root your phone (on first occasion I flashed a pre-rooted .236 version but that caused some extra trouble so next time I decided to flash an unrooted version). And from then on it's the standard way as you described it in your OP.
Good luck!

Okay, thanks a lot for your hint! Unfortunately the camera mod didn't fix the problem, my android-task for this evening is defined:
AICP 13.1 Oreo 8.1 on z1c, root, ulb, magisk 17.1
1. backup my system (done)
2.0 flash stock rom lollipop 5.1.1 (14.6.A.1.236.ftf) with flashtool via usb (done),booting the os for the first time takes quite long (~10m), check camera in the os (done)
interesting fact: recovery is deleted by flashing the rom via flashtool - I thought I can go the lazy way and skip the step of installing twrp again into recovery
2.1 okay, let's do it: install twrp (done) and boot into twrp, NOT into ROM!! (done) (Vol- & Power, wait for vibration & release Power but keep Vol- until TWRP starts up)
3. flash aicp 13.1 following this (full wipe as an advanced wipe: select all EXCLUDING THE SD STORAGE)
Again here, I recognized the first boot of the rom takes quite longer.
4. check camera (done)
!!!! IT WORKS !!!!
(I did it two times)

alright, lets start flashing my second device - now I know how to do it
Thanks guys!!

btw @lm089, boots your ota-updater directly into twrp and start the flashing procedure? In my case I had to boot twrp manually and flash the zip manually, too

No, updater is booting into recovery, doing a nandroid backup and wiping caches (because I told it to), then flashing and finally rebooting into system. All by itself :good:
I remember having trouble with that in the past though. Do you by any chance have an SD card formatted as adoptable storage?

Yes, its used as an external storage

ok, that's something different; adoptable storage means that your SD or part of it is setup to extend internal storage. If you can access all of your SD from TWRP then it is indeed formatted a external storage.

Planning to flash custom rom on Redmi Note 8T, have I got the steps right?

Hello, I am poised to start customising my Redmi Note 8T. I've done loads of reading and have an outline plan but would appreciate a sanity check / review of this in case I am either missing something or doing something I shouldnt. Phone is currently encrypted, TWRP can unlock it fine. I want to end up with an encrypted device but there is nothing precious on the phone at the moment (stock MIUI as delivered, pretty much unused since the unlock factory reset).
Here's what I have following my research on other threads here:
First, what I have done already:
0. get phone Redmi 8T willow 128GB with stock MIUI (DONE)
1. unlock phone (DONE, 7 day wait!)
2. flash TWRP (DONE, used 3.3.1-1 official version, but MIUI overwrote it when I rebooted)
3. Backup from TWRP (DONE)
Next, the to-do list:
4. flash vbmeta (fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img)
5. flash TWRP 3.3.1-10 version (fastboot flash recovery twrp-3.3.1-10-ginkgo-willow-mauronofrio.img)
6. reboot into TWRP (fastboot reboot, hold volume up + power)
7. Wipe /system, /data, and /cache
8. flash Havoc-OS-v3.2-20200229-willow-Official.zip
9. flash open_gapps-arm64-10.0-pico-20200229.zip
10. reboot & test
11. reboot into TWRP (fastboot reboot, hold volume up + power)
12. flash magisk zip (Magisk-v20.3.zip)
13. flash disable_dm_verity zip (Disable_Dm-Verity_ForceEncrypt_02.24.2020.zip)
14. reboot & test
15. Install via magisk manager the SQLite3 binary (SQLite3.Universal.Binaries.v1.0.zip)
16. Reboot
17. Install vis magisk manager the GPay SQLite fix (GPay.SQLite.Fix.v2.0.zip)
18. Reboot
Thanks very much in advance.

Hey @ogpog, at step 4, where you find vbmeta to flash?
Thanks

You did well with the steps outlined above??

nothing is clear, not really..to many gray areas..like can i backup rom to external sd card, why exactly in twrp do you backup rom wise, and Disable_Dm-Verity_ForceEncrypt_, iv read its two files in one, new roms are not like the old days ie marshmallow kitkat, i used all in one tool flashed twrp..all went well then flashed then flashed magisk and then the dm-verty thing, ended up in a bootloop, then tried to use mi flash tool to put original firmware back, error error, got back using twrp and using eea recovery rom, although i was on on global, remember fast boot rom is not the same as recovery rom, same rom though, all very confusing...for me anyway.

Just looking back over my notes from when I did it. Here is what I wrote:
A modified vbmeta.img disables verify boot on devices using Android Verified Boot. You need to disable dm-verity on the fastboot command:
Code:
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
source https://forum.xda-developers.com/showpost.php?p=81591273&postcount=196
(the above is a command-line given on your computer connected to your phone which has been booted in fastboot mode (boot phone with power+volume down). You need the fastboot command on your computer (I use Linux and it's in a package called "android-tools").
If you forget to flash vbmeta, you'll see a message "the system hass been destroyed". Just go back to fastboot mode and flash it.
This is the process I recorded, but please verify it rather than folllwing it blindly, and bear in mind that later versions are available now .
Code:
0. get phone Redmi 8T with stock MIUI
1. unlock phone (DONE, 7 day wait!)
2. flash TWRP (DONE, used 3.3.1-1 official version, but MIUI overwrote it)
3. Backup (DONE)
4. flash vbmeta (fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img)

I get your sentiment - it's feels hard doing this on any Android despite having decades of expert level professional computer experience. But it's really a miracle we can do it at all and we have the good people providing roms and the information needed to install them to thank for that. I think the "brick fear" makes it worse due to the lack of a console port or bios to fall back to like you have on a computer. I think the first post in the thread should contain all the information needed to install the rom but it's a moving target so I guess it's a difficult call to expect it to be maintained.
If I were to call out for one thing, it would be for that page to also include instructions for Linux. Android is Linux after all
(sorry I just realised I wasn't on the havoc thread where the "first page" is - https://forum.xda-developers.com/redmi-note-8/development/rom-havocos-3-1-t4043973 )

Thanks for your interest, I just wanted to know if the steps you describe were correct. I had 2 systems destroyed and it's not funny. Hopefully it works

TWRP does work above 12.0.5, I have tested.
New build: https://tdrive.elytra8.workers.dev/image-new.img
Flash like you flash any other custom recovery.
For ADS in MIUI, using debloat tool and removing MSA does the job.

Uhm... hello, newbie here and hopefully in the right thread.
I have a Redmi Note 9 and wanted to install LineageOS. What I have done so far:
Jumped through all the hoops to unlock the bootloader.
Since that erases all user data, I did not bother setting a password in the setup. Just went through it as quickly as possible.
Installed TWRP 12.0.6
Used that to install lineage-17.1-20210209-UNOFFICIAL-merlin.zip from here.
Result: The new system does not boot. I always end up in TWRP again. Even if I specifically go to Reboot -> System, it'll boot into recovery. I think the first boot fails and then it goes into recovery (if I power the device off and on again, it vibrates, the logo comes on, the screen goes black, it vibrates again, the logo shows again, and then I'm in TWRP).
What I have tried unsuccessfully:
Flashing the vbmeta from here.
Erasing the misc partition.
Flashing the old lk from here.
Closing the AVB2.0 after flash (with and without closing DM verity).
Wiping cache, dalvik, data, internal storage, and cache before reinstalling LOS.
Replacing TWRP with PBRP and trying again.
Probably some other things I don't remember. I've been chasing red herrings through this rabbit hole all day.
I also tried to install the ArrowOS build (from here), just to have one more datapoint. After that, the device boot-loops into the bootloader, and I have to manually go into recovery via VolUp+Power. This leads me to believe that it's not the LOS build at fault. It seems more likely that I am a moron and am doing something wrong. I just can't figure out what it is.
Any help would be appreciated.

Hey, Custom roms for Redmi Note 9 need MIUI 12.0.1 Indonesia, or MIUI 12.0.3 global vendor.
Downgrade your phone to the specific MIUI vendor, and then try flashing custom rom.
Here's the link for global 12.0.3
Xiaomi Firmware Updater
The ultimate script that provides firmware packages for Xiaomi devices.
xiaomifirmwareupdater.com
And before you downgrade your miui version, please erase system and vendor to bypass anti roll back.
Use these commands after connecting device in fastboot mode:
fastboot reboot fastboot
fastboot erase system
fastboot erase vendor
fastboot reboot bootloader
Then flash the 12.0.3 global/12.0.1 Indonesia miui version through MiFlash.
Or
You could give flashing 12.0.1 Indonesia vendor in TWRP, and then flashing rom.
If after fastboot reboot fastboot it shows waiting for device, install this driver. https://drive.google.com/file/d/1JFYCZ3mu_Y_xpnS7QrmtwqOeFnWg6DO2/view?usp=sharing
Please note that you need to be on stock recovery for fastboot reboot fastboot to work.
Happy flashing

Thank you very much! With that info, I think I finally have it working!
I case it's helpful for future users, here are some issues I encountered along the way:

Is that normal? I do have a partition named 'super' that I can see in the TWRP backup module. Judging from its size, that could be the system partition. I think there's also a vbmeta_system and vbmeta_vendor, did you mean those?

Ok, so I downloaded the full ROM for 12.0.3 global. I'm using Linux, so MiFlash won't work. But the ROM archive I downloaded contained a bunch of partition images and a shell script that would flash them using the fastboot command. I just ran that script. Windows users probably could have run the .bat file that was also included. There were no errors. And after a reboot, MIUI started to boot and presented me with the setup procedure.
I did not complete the setup (I suspect it would have just auto-updated MIUI to something that would have caused problems again) and used the power button to go into the bootloader.
From there, I flashed TWRP again (since it got overwritten by the script mentioned above), went into recovery mode, and tried to install LOS again. First, flashing seemed to hang. The last messages in the log were:
Code:
Installing file '/external_sd/Download/lineage-17.1-20210209-UNOFFICIAL-merlin.zip'
Checking for Digest file...
Target: Redmi/merlin_eea/merlin:10/QP1A.190711.020/V11.0.2.0.QJOEUXM:user/release-leys
And that was it. The border around the progress bar was doing it's busy animation thing and after waiting for 10 minutes, I used the power button to reset the device.
The second attempt went through fine, and now I have LineageOS running on the device. I still need to play around with it some more to see if there are any issues, but the flashing itself seems to have worked.
Again, thank you for your help!

Oh you're using Linux, for Linux the commands is
/.fastboot reboot fastboot
Great to know you were able to flash successfuly. Note that first boot in all roms is a bootloop, you just have to force reboot after a minute of bootlogo showing up or so.

hi i flashed a wrong twrp and now the phone keeps bootlooping, cannot enter recovery or fastboot by power + vol (+ or -)
adb from computer doesn't detect
sp flash tool doesn't move when i hit "download" button
bootloader unlocked, root yes
pc notificates a device connection by sound

thank you for the help really cannot figure it out

Apparentely, you need to flash in EDL mode.
So, you need to bypass the authentication in EDL mode first.
Read this: https://forum.xda-developers.com/t/...d-flash-in-edl-with-no-auth-for-free.4229683/

Newbie Android user here, hopefully i’m on the correct thread...i have a Redmi Note 9 with MIUI Global version 11.0.5 and Magisk version 20.4.
I tried updating Magisk to the latest version using the direct install option but I keep getting an error. I was told I need manually patch the boot.img and flash it but I need to create a magisk_patch.img first from the boot.img.
I read some of the guides on this thread but I’m not sure which one to follow. Also the steps to create the magisk_patch.image shows I need to click the Install button on Magisk then Select and Patch a file. I only have the Update button on Magisk, can I use that instead?
Or if you have other suggestion how to fix my issue. I attached the error I’m getting when I’m updating Magisk.
Thank you in advance for the assistance.

You can't install the magisk using the direct option.
You need to the patch the boot.img file and then flash the magisk_patched.img using fastboot (or spflashtool).

HELP PLS
i first flashed the patched_magisk.img then i got in a twrp boot loop. When i try to reboot into the system i get back to twrp menu.
Then i panicked and went to WIPE and factory reseted,
but it got stuck again. Then i powered it off.
How do i get out of this? I wanted to flash the stock boot.img but the storage folders has strange names
EDIT:
i figured it out what i have done. The data was ecrypted so i formated the data. But now i have another problem:
I installed linageOS from here, but when want to reboot back to system it says
No OS Installed! Are you sure you wish to reboot? i don't undertand why the custom rom didn't install.
I just copied the .zip file with the custom rom in the phone and hit install in TWRP. What did i do wrong?

Steps for flashing vbmeta are same for every device.
You may try to use the search.
Here, you can find patched vbmeta for MERLIN:

no, i mean a full guide for rooting from the beggining to end, for redmi note 9. For example i missed the vbmeta and this resulted in an error. Now i have to flash the stock firmware and wait for another 7 days for it to unlock. For newbies like me, this looks like a mess. If you don't have one, can you please create one? Do it for us, newcomers. Thanks

Flashing failed completly, could repair it. What do i do now?

What happend:
I bought a used Mi A2 lite with stock Android 8. Because i already used LineageOS and really love it, i want to continue to use it.
I did the flashing process a few times wrong. After the help of a very kind user i did it as it was supposed to be.
mustaphakosar said:
Let me sum up the process which will probably answer your all questions.
Once you opened the bootloader and flashed TWRP image successfully and saw TWRP screen on your phone, unplug it from PC.
IF you will install a custom rom, than
1- format data, type 'yes'. Reboot to recovery
2- advaanced wipe( everyting except sd card) (ı assume you should have put custom rom file and twrp.installer.zip to your sd card)
3- install custom rom and twrp.installer.zip(choosing to upload from your sdcard, you will be able to see them)
4- go back. Press "reboot" but don't reboot anything. From reboot menu, change slot(if you're at slot 'a', change your slot to 'b', vice versa)
5- now you can press reboot to recovery.
6- once recovery(twrp) opens, you can install gapps and magisk.
7- reboot the system.

Doing so cause, that my Phone didn't boot the OS anymore. I could see the Android ONE bootlogo, after that the screen turned black. Phone must be still running because PC detected a device, when i connected the phone to my PC.
If i keep pressing Louder and Start i could enter recovery, with quieter i could enter fastboot.
Thankfully i discovered this thread:
never ending boot after stock ROM install
My Mi A2 Lite had stock rom v10.0.18.0, unlocked bootloader, Magisk v20.3 and TWRP using Offain v3.3.1. I wanted to try dotOS custom ROM and followed this tutorial: https://github.com/tkchn/daisyinstall I begin with step 1 installing daisy...
forum.xda-developers.com
and fixed the Phone so i can start an OS again. Now is my question, what did go wrong? What is the best way to continue from this point to flash LineageOS on my phone? Do i have to update the OS from the thread first and try it again?
Phone is still OEM unlocked.
Thank you guys in advance!

Ok i got it now. For whoever will find this in the future:
I started at the point above and updated the Stock Android 9 to the latest version.
1. Enable USB-Debugging and open Bootloader in the settings
2. Shut down Phone and start into fastboot
3. Use command: "fastbood oem unlock"
This will cause a factory reset, be aware
4. Check settings and go into fastboot again, then use command
"fastboot boot <name of your twrp image>"
Proceed this way:

Question Latest Twrp pros and cons

Today the unlock time for bootloader to unlock will complete and I Intend to install TWRP. I have found the latest officially supported twrp-3.6.1_11-0-alioth.img at https://eu.dl.twrp.me/alioth/. How does it compare to TWRP-3.5.1 https://forum.xda-developers.com/t/recovery-unofficial-twrp-3-5-1-20210702.4300189/.
Can anyone guide me what are the pros and cons of using twrp-3.6.1_11-0-alioth.img and its limitations as compared to TWRP-3.5.1 as I can not find any documentation on twrp-3.6.1_11-0-alioth.img. Any help will be appreciated.
Also does the following limitations of TWRP-3.5.1 also apply to twrp-3.6.1_11-0-alioth.img ?
KNOWN LIMITATIONS:
The following are some known limitations due to either the design nature of Virtual A/B or a problem with ROM themselves. Please read carefully :-
You cannot format data after flashing a ROM zip (Limitation of Virtual A/B). If you want to format, then reboot recovery after flashing ROM. Additionally, if you are encrypted, the newly flashed ROM must be able to decrypt your device. If not, then you have to format data before flashing the ROM It appears, you can actually format data after reboot even if the new ROM cannot decrypt.
You can flash only one ROM in one boot. If you wanna flash another ROM, you must boot to system once. This is again a limitation of Virtual A/B.
Once you have rebooted after flashing a ROM, you cannot write to the data partition until you boot successfully to the new ROM. Android seals the data partition after a ROM flash to prevent any accidental brick since the newly flashed ROM is actually stored in /data. Only data format is allowed in this case. Once you successfully boot to the new ROM, your storage becomes ready for writing again.
Ideally, after flashing a new ROM, you should only need to wipe your data rather than format. But, due to a problem in the device trees current ROMs are using, you will have to format data if you are currently on miui and want to switch to a custom ROM. Specifically, the roms need this commit and to set vendor security patch level to fix this issue. Switching between custom ROMs should not need format, except for hentai OS.
If you are currently on hentai OS, then before using TWRP, you must flash vendor_boot from the link provided in every hentai OS release. Otherwise, you will get black screen. This is only needed when you boot to TWRP for the first time. Do not repeat this step again. Also, do not try this with beta version of the ROM. Use it only with stable.
If you reboot to older slot after flashing new ROM, the new ROM will be cancelled and you will have to reflash again. This is because of how Virtual A/B works.
If you must flash magisk via recovery (it's not recommended now), please uncheck "Inject TWRP after install" else TWRP will remove magisk.
Do not flash magisk after flashing a ROM before reboot. Magisk's zip detects slot in a different way that will cause issues.
Backuptool (used to persist magisk and gapps across ROM updates) will also not work in recovery due to A/B. You will have to flash gapps (or any other zips) everytime after flashing a ROM.

I know where the lastest TWRP for Poco F3 is and how to install it as I have already installed it. That was not the question. The question was that "does limitations of TWRP-3.5.1 also apply to twrp-3.6.1_11-0'? Limitattions like being forced to reboot TWRP after flashing a every single zip file and other limitations like it as mentioned above. Thanks for your reply anyways.

so for me, TWRP does not start again, after installing a file.
I install TWRP, boot into TWRP again and install Magisk. after that I boot into the ROM.
TWRP does not restart itself

So, still no decryption on A12?
I wanted to test new custom roms but i dont want to have to reinstall everything from scratch if i go back to my current rom (.EU).
Can twrp make a full backup and restore it despite not having decryption?
If it cant, can I make a full back up of my phone from cmd in fastboot mode? (so i can just flash it from fastboot to restore everything as it is now)
