Question Can´t rollback to Android 11 - OnePlus Nord 2 5G

Hi.I´m trying rollback my Nord 2 from Android 12 C.13 (EU version), to Android 11 in order to install TWRP and flash any ROM. I´m using the offical method as this official link https://community.oneplus.com/thread/1596759.
The file I download start to install but at the end I´m still on A12. Anyone can help me?- Thx

Try other version. When I was trying wrong, it stops at 15% and reboot without change.

I tried Global and EU versión and both failed. I'm living in Spain. I suppose that my Nord runs EU version.

Ur loosing all ur data by rollback.....u can try to factory reset before rollback. Maybe this make a difference.
Are u rooted ?
Maybe unroot first ?
Did u renamed the file ?

I´m not rooted. I renamed the file correctly. I´ll try factory resert before. Thx

If still not work maybe wrong destination. It's need to be in memory (not in any folder)

[Q] Flash Original ROM

Hi guys,
I bought an LGP500 yesterday and I'm already messing with it *ofcourse* I'm trying to root the device and install some ROM's. At the moment I'm on Android 2.2.2 (V10h), so no rooting is possible (yet).
I figured out I have to flash back to the original ROM, and then start flashing to a prefered ROM, but I can't find an original ROM from Belgium in the list The_ERROR provided.
Could I just take another original ROM, fe. the one from the United Kingdom, root the device, flash another ROM and still have the possibility to have my Android phone in dutch language, or do the custom ROM's only support the English language?
Thanks in advance!
Hmm, after some reading I think it should be possible since most custom ROM's are stripped from the European one..
Can someone still confirm this?
Have flashed my phone to the 10a UK version, but I get an android.process.acore error the whole time and I'm unable to download anything of the market (I need ASTRO file manager so I can run z4root).
Any tips?
Hi,
I also just bought P500; I am wondering since you flashed a completely different ROM, what are the dangers? I cannot find my original ROM so I was wondering if I will brick my phone if I just use another one.
Well, I checked what software version my phone had (10h after the LG update) before the flash, and I found an according european original firmware 10h KDZ, so it's kindah my backup I guess. If anything goes wrong, I just flash my phone back to the 10h
I think there are no real dangers here, only not all languages are supported. I'm not sure though

1st install z4root then root ur phn after rooting i will tell u what to do...go ahead
The problem I have is installed z4root. The only way I know how to install an app from the SDcard is through ASTRO file manager, but somehow I can't download any apps from the market after the flash
Is there any other way I can install an apk from my SDcard (without root)?
The problem I have is I can't instal z4root. The only way I know how to install an app from the SDcard is through ASTRO file manager, but somehow I can't download any apps from the market after the flash

Aha, I installed another original ROM (10a EUROPE), and I still got the same problem.
But I tried a reset (or how do you call that) by pressing POWER + VOL_DOWN + HOME, and my 10a was installed succesfully, with everything working like a charm.
Now I can root and flash to custom ROM's Yay!
If anyone else has problems, I'm glad to help you guys out.
After you flash your device down to 2.2, from 2.2.1, is it possible to go back to your original 2.2.1 somehow? is there a way to back this up before flashing to the original 2.2?
^^ no. nandroid backup is possible but only with 2.2 as it needs root & custom recovery.
Yes, you can find the original ROM's here: http://forum.xda-developers.com/showthread.php?t=875881
I'm not sure which version represents 2.2.1 but I think it was 10c.. not sure though
I'm sure about 10a being 2.2 and 10h being 2.2.2
Good luck
should i install 2.2.2 for my phone ?
now using 2.2.1,maybe want to reinstall the rom again
coz my phone keep hang,example switch on phone hang,open an application and jump to homescreen and other else
and can i know the country code for malaysia ?
i can't find it at all
If you only want to update your phone (without using custom ROM's), you can just use the LGMobile update to flash your phone to the newest version

[Q] Huawei U8860 Read-only file system

Hello Everyone,
I badly need help on my Huawei Honor U8860 phone. I have recently updated it from 2.3.6 to 4.03 over WIFI and the update went smoothly. So now here is what my phone have:
Kernel Version: 3.0.8-perf-00059-g3a757a2 [email protected] #1
Build Number: U8860IV100R001C00B923SP01
I have not rooted the phone at this time. It was working fine until 2 days ago when I started getting messages on the screen like:
"Unfortunately, 2D Home has stopped"
"Unfortunately, Google Play has stopped"
"Unfortunately, Contacts has stopped"
"Unfortunately, Settings has stopped"
"Unfortunately, Google Play Music has stopped"
"Unfortunately, Browser has stopped"
And so on, and so forth. It seems that all apps and processes have stopped when I try to use them so I literally can't use the phone. I went through several threads here just trying to restore my phone back to a
working state. I tried to do the following in order but without success:
1.) Factory data reset / erase everything - the phone boots to the recovery menu then it formats the /Data, /Cache and /HWUserData then it reboots. After reboot, the phone is back to where it was before the factory data reset with everything in it including downloaded apps.
2.) Manually uninstalled all downloaded apps. Removed screen lock (just to see if phone behavior changes). Then rebooted the phone but after reboot, all the apps are still installed and the screen lock is back as well.
3.) I tried to Force Update with the following official ROMs: B886, B919 and B923 but I always get the message "Update failed" during the update process.
4.) I downloaded the file "recovery-u8860-en.img" so I can replace the "recovery.img" file . Rebooted the phone w/ the pink screen and connected it to my PC but there is no USB mass storage device mounted.
5.) Finally, I tried to root the phone. I enabled USB debugging. I installed the ADB drivers then I downloaded the U8860 root tools and rootexplorer.apk. When I ran the "root-me.cmd", it tried to copy some files to the phone but it failed. The error was "read-only file system".
So it seems that the problem is because of the "read-only filesystem". I does not permit/allow any changes made to the phone. Can you help me restore my phone?
Please.. Can somebody help me on this?
Thanks, clint2rose

I still did not find any solution for my problem. I read from this thread that all ICS versions can be downgraded.

Is there a way to downgrade from B923 to B919? I think this will solve the problem I'm facing.

try to back-up some of the data form the partitions that are full on your phone and delete them, maybe afterwards the stock-rom-flashing procedure will work again.

thanks for the reply. it did not work. I even formatted the internal SD. Re-run the firmware update but it failed. when i boot the phone, all the contents of the internal SD remains intact. any other suggestion?
I can remember there was some talk of "downgrade patches" to flash before official ROMs if downgrades failed

I downloaded the files from both links. Can you tell me how to flash my current ROM? Because when I tried to use the file like a regular ROM (I created dload folder then put UPDATE.APP in the folder, then ran firmware update.. the update failed)..

what do you mean by flashing your current ROM? Just like any other stock ROM put the dload folder on the sd-card and start the update procedure either from the settings menu or via the boot-key-combination.
Yes the way you discribed is the correct one for flashing those patches, If those patches also don't work, I'm out of ideas, sorry.

Thank you once more for your time. Most of the thread I read regarding these patches often used the phrase" you have to flash the current version of your ROM using the patch"...
And yes I created dload folder, place the UPDATE.APP and put it on the sdcard. I turned off the phone and removed the battery. Then I pressed vol+ vol- and power on/off button. The firmware update went to about 70% installing before displaying update failed.
I guess I will have to bring my phone to a repair center. My only problem is that there is no Huawei service center at my place (I reside here in Saudi Arabia). I got the phone as a free device on a broadband package and the warranty is already expired. I'm a little worried to take the phone to the small mobile repair shops as they might screw up the phone even more. Huawei is not a popular device here unlike iPhone, HTC and Samsung Galaxy.
As I understood that your device is rooted, you should get some custom ROM and try to install it.

you don't need to be rooted, you only need to have a custom recovery deployed (which you can either do with root permissions, or by using the pink screen method, but some newer stock roms (you said your on 932 or something? last non-locked working is b919) this has been locked and the device will not boot if the kernel or the recovery image has been manipulated.
I think you will have to find some (huawei-certified!) repair-center, small do-it-all phone-shops probably won't be able to take care of this problem for you.. I'm sorry but I don't see any other solution

Ok. I will try to find a repair-center experienced in Huawei devices. I have one last question if you don't mind. Is it possible to erase everything on the phone? As in completely erase or reformat after which there will not be an operating system on the phone. I read in some threads that this is possible w/ custom recovery but I want to know if it is also possible for phones without the custom recovery. I'm hoping there might be some tool or something..
U8860 not responding

Have you find the solution yet? I have the same problem. Somehow my phone system is "locked". I can't install or uninstall app. Some google apps keep showing not responding. Everything changes i made, keep showing up after the phone rebooted.
This was happen a few days after I upgrade to ICS B932SP01 and rooted my phone (to remove original chinese apps).
Luckily i have friend in huawei indonesia. He gave my u8860 to the technical support. But the result was no good.
They try everything, even install my phone with the original GB and always failed.
The last suggestion is change the phone machine, which is as same as buy a new phone.
I really appreciate is someone can help me here...
Thanks

[EMUI 5.1] OTA Firmwares and Unbrick Phone method

Consider one day you upset the devil and your phone is bricked by him, lets try to revive the phone from hell (at your own risk) :
Link to the OTA firmware's :
Click here for the links page
Important tools links:
[TOOL] Huawei Multi-Tool v8 by Team MT by inside!out
TWRP Honor 7X img
Stage 1
Download from here everything you need for the procedure - Download Folder Link
I am testing it on my BND-L21 firmware from BND-AL10
Downloading firmware (from topic). Full firmware must be more than 1.5Gb, all smaller is just
OTA Updates to the system.
After that we must download Huawei-MultiTool (future MT) version 8.x.x (link topic)
and downloading custom recovery. We will use TWRP for Honor7x (link topic)
Last we must prepare OTG Cable, SD Card more than 4Gb. On first stage that's all.
Stage 2
Go to MT and reboot phone to Fastboot mode (while phone off, hold "Volume -" and power)
If you did all correctly, you will see in the down right side your number and "Fastboot".
Now go in MT to the Bootloader and check the status. If you have already unlocked, skip this.
If you have locked phone, you must have IMEI and Huawei account. (if not please unlock your bootloader via the Huawei site)
After that, go to Recovery menu and choose our TWRP image in "Custom recovery" section and
type "Recovery". IMPORTANT!!! DON'T FLASH ERECOVERY, I DON'T HAVE THIS IMAGE!!!
After flashing recovery, we must turn off our phone.
Now we must to prepare base system image. In archive we have UPDATE.ZIP file. extract this
file to custom folder and open "Unbrick" in MT and choose "extractor". Open our file in extractor
and click right mouse key on empty space, choose extract all... and choose custom folder to
extracting.
Go to the folder and copy file VENDOR.IMG to the SD-Card (or USB with OTG). Turn on your
device in Recovery mode (Volume + and power), choose Wipe and Wipe ALL partitions! After
doing this, go to Install and choose "Install img", go to the SD-Card, and install VENDOR.img to
VENDOR folder (Important!)
After installing reboot phone again to Fastboot mode and connect to PC.
Now we must download .zip update to your region. We need this for using LTE (4G) in your country + Localization.
After downloading open .zip archive with our CUST file. archive must be called update_BND-
YOUR-NUMBER_hw_YOUR- COUNTRY.zip
From this archive we must extract .img file from root folder. It can be called cust.img CUST.img
version.img etc.
if name different from CUST.img rename it and put to the extracted UPDATE.app folder.
Last Stage 3
In MT go to Unbrick, choose our unpacked system with our CUST file and we must have at least
4/5 checkbox. And just type "UNBRICK" and wait. NOTICE: at moment of extracting system.img
it will be about 10-15 minutes. It's not a freezing of PC)
After good installing in log you will see like "All ok" Just reboot phone and you will see low level
factory reset, or something else like formatting. After formatting phone will reboot to the system.
That's all
Flashing Gapps method coming soon...

there is a procedure used by EU users to completely revive the phone using the OTA but the procedure is too long which i haven't tried yet and is completely for users who have dead phones for now and yes obviously there is no official firmware available for Honor 7x but the user from an EU forum revived his phone so it is possible from the images.
though i made this thread for users who want to update their firmwares and not the procedure to flash a stock firmware since there is not one available yet but i can point to the thread where this user posted the procedure if someone wants to try. PM me

There are teams who have unlocked a lot of stuff like flashing international FW,
flashing gapps on chinese fw, Automatic Call Recording, restoring the phone.
so i am in contact with them to make our phone better. lets keep our fingers crossed. :fingers-crossed:
i am waiting for firmware flashing to get it translated from one of the users.
This is the full recovery package right? Atleast for the Indian version?

They arent recovery packages. they are full OTA which can be flashed for updating.
but there is a process to compile them into making them stock firmware packages but due to the long procedure i didnt post it here. rather wait for official stock firmware package.

Hello Honor 7X Users, turns out there is firmware available for flashing for the AL10 and L21 variants
but i haven't tried them out and can post the procedure if someone needs it but all credit goes to PRO-TEAMMT for releasing them for us so now if we mess up we got official firmware's latest available to go back to.
I personally haven't tested any but i soon will.

this is to update to the latest firmware. if you have the latest firmware you dont need it.
the multi tool is used to flash stock with a procedure which is only needed to return to stock or else theres no need for it for the most part..

3) Yes, if you don't know what you're doing. No if you're not going to be flashing anything.
4) You should be able to and also refer to #1.
5) None available
6) None available
7) You can't, no stock image released = no procedures to unbrick

1- can i upgrade the system at every update (when the device is rooted) with Firmware finder many times even if I don't recive the notification on the phone of the update (or if the device updater cannot find it)?
2-ok but if do all right steps you cannot brick the phone, no?
3-ok i only wanna unlock bootloader, flash twrp and root the phone. If I do all right steps there are no risks, no?
4-i don't understand it (in hisuite there s the option that says "Update device". With the device rooted can I update the phone with this software?)
5-ok but can I do one with a custom recovery, no?
6-ok so we just have to wait, no?
7-ok. Same thing of the - 6 (we have to wait for the UPDATE.APP for the 7x to be able to UNBRICK the phone in case it could happen, no?)
Sorry for my bad English and thanks for the answers?

1. yes you can if the app supported honor 7x with their firmware but it doesn't yet, use twrp
2. yes you can upgrade via flashing it in twrp
3. unlocking bootloader itself is dangerous let alone rooting since your waranty is gone since there is still no sign of official stock firmware
4. same as no. 1 ans
5. if u flashed twrp you can do your nandroid backup which can be later restored anytime so it will be obv on the phone at that time
6. manual or local update? in the op main post i guess? by opening the link?
7. Still no official firmware and the procedure i am aware of consists of turning the official chinese firmware into normal by changing settings and stuff which is a long procedure so probably if u brick, u r stuck until honor decides to release stock firmware
by the looks i guess you have no clue about phone flashing, its better you dont try anything until there are guides properly made for newbies. :silly:

1. yes you can if the app supported honor 7x with their firmware but it doesn't yet, use twrp
2. yes you can upgrade via flashing it in twrp
3. unlocking bootloader itself is dangerous let alone rooting since your waranty is gone [emoji14] since there is still no sign of official stock firmware
4. same as no. 1 ans
5. if u flashed twrp you can do your nandroid backup which can be later restored anytime so it will be obv on the phone at that time
6. manual or local update? in the op main post i guess? by opening the link?
7. Still no official firmware and the procedure i am aware of consists of turning the official chinese firmware into normal by changing settings and stuff which is a long procedure so probably if u brick, u r stuck until honor decides to release stock firmware

I rooted my 7X(Al10) version successfully but while performing the reset, deleted the system file also by mistake. There is no TWRP backup. Is there any way to get the stock OS files again to flash in TWRP ? Or does anyone have a backup file they made that they can share? I tried Huawei e-recovery too, but that gets stuck at 'unable to get package info'. The people at the service centre can't think of any other method to restore the phone, except changing the motherboard. When is the official stock file expected to be available?

I have a TWRP backup not sure if it'll work, https://drive.google.com/file/d/1EntdgNwcJSOTZizqt_W-yWfkd3-YVmCm/view?usp=drivesdk
It's a zip file with 2 backup folder, one with boot and system and one with vendor
Edit: pls thank if it worked, so I have an indicator of the effectiveness

1. In the app firmware finder there are firmwares for the phone but how can I flash a official firmware (OTA I mean) if there are no one (or how can I flash a firmware finder Update)?
2. Same thing in -1 (I mean)
3. Ok. Now we have to wait the official stock firmware, no? (i don't understand this answer, please write it in another way)
4. I don't understand it
5. Okok (obv? Sorry I'm Italian hahaha)
6. It's not the same thing local or manual? Write it in another way please hahaha google translate doesnt help me?
7. Okok, So if I don't use your method I only have to wait that honor release the official stock firmware (UPDATE. APP). And for greater security it's better wait it before to root and unlock bootloader etc, no?
Anyway, I have an idea of ​​what flashing is, in fact every device I have (they are all Samsung, so that's why I'm disoriented) is completely modified. The fact is that I dont have much experience (I'm 14 years old) with non-Samsung devices, in fact my honor 7x I received for Christmas and for the hurry and the want to modify it, I would like to know all these things.
Thank you

OK thanks I'll keep it aside in case of brick
I would recommend everyone to not do experiments over your phone to try and root and flash random stuff..
they only have official chinese firmware for flashing so its better to wait for the official firmware for non chinese version.
the method which i know of to flash on the phone is for people with flashing knowledge cz the procedure is not simple and secondly even i have been flashing my phone for many years on various devices yet i havent got the guts to root this first honor device cz their partitions are different and somewhat secured so dont play with it.
wait for the official firmware for your respective devices. maybe they will straightaway launch the oreo firmware.

Help returning to stock

Hi all,
hoping someone can help me out. I flashed the Lineage rom and i got it working ok however i missed google pay so i decided to return to stock.
i tried placing the update.APP in the dload folder and running the force update procedure but it fails at 5% with just an update failed message. I have tried using the erecovery to download recovery and rom but that says it failed to get the package information, i have tried flashing the images from the update.app using fastboot but theres not really any decent info on which bits i need to flash to get it fully back to stock (and relocked)
If i try fastboot relock
Code:
i get error, root is risk
EDIT: fixed that if anyone needs help

OK. Tried doing the parts about the public zip and hw zip and they are not found on the site so I'm hoping that doesn't matter on this phone. Did you have the same result?
EDIT: Nevermind, i was being an idiot, downloading the files now
All working as new now, but newer firmware. Thank you so much for your help!

Hi
Could you tell me how you removed the root, I am having the same problem on my Mate 10 Lite, I want to return to stock, but it eludes me all the time because of root. I have used what should be non-rooted backups, but they say root. The only backup that worked ended up turning my phone into another unit so no luck there either. Would love to hear how you did it?

How To Guide Downgrade US OEM (DE2117) Android 12 firmware to Android 11 BEFORE installing Lineage!

Lineage installation on N200 REQUIRES that you are running Android 11 or phone will soft loop after installing the Lineage boot.img
If you are updated to Android 12 firmware and want to install Lineage, you MUST downgrade first to:
DE2117 OEM Android 11 FINAL OTA
WARNING: This WILL erase all user data.
1. Place the firmware .zip file in the user root of internal phone storage.
2. Sideload OnePlus firmware Downgrade Tool on phone and use tool to flash the Android 11 firmware.
There is an Emergency Firmware install tool that OnePlus posted to the OP forum that does NOT check root status when the need to downgrade back to A11 was first acknowledged due to modem issue with first A12 OTA release.
This file was removed in a few days when they posted the official Downgrade tool replaced it.
I have used this tool to upgrade DE2117 C_16 to DE2117 C_17 while rooted and the built in upgrade tool failed at 37%.
Nice, first thanks for the hard work you're putting in. Second, is there an advantage to converting first to DE2117 then installing lineage as opposed to just installing lineage from DE2118 that you know of? I know in the other post you answered my other question stating that the Lineage will install on either so I wasn't sure if I'd get any benefit from starting over and converting my DE2118. TIA

Lineage is using own kernel and boot.img on A11 so in the short run it is not going too make any difference, but when Lineage moves forward to A12 the OEM Firmware has newer drivers and is updated sooner, has more OEM features and bugfixes as well as no carrier bloatware.
It is possible that OP will neuter the Carrier firmware with an OTA update to prevent cross flashing device away from the Carrier rom in the next OTA update by preventing fastbootd from flashing the us oem from a carrier phone.
They have already removed fastboot boot command to boot a boot image without flashing it for test before you flash and to allow Magisk to make a backup of the original boot.img before adding Magisk.
I would convert NOW, before they decide to slam the door on this ability with a future OTA that will not allow you to downgrade and prevent this as they are under contract with the carriers to not allow this to be done.
Ok, thank you for the explanation. Guess I'll back everything up and convert it.

This worked perfectly after following your convert guide and upgrading to 12. Downgraded back to 11 so I could install lineageOS. Thanks again!
This reddit post has a link to an English version of the downgrade apk which makes it a little easier.

Did you remove root (Restore boot.img) and then factory reset?
You will loose all data doing this anyway.
I m trying as well .. but stuck with verification failed message just as scanman0 I m on stock android12 no root if anyone know how to fix it ... please assit
I just downgraded. Make sure you remove root via magisk. Then proceed to rollback to Android 11. Everything worked fine. I'll install lineage tonight when I get home.

I did not have to remove root. I used the version posted that does not check for root but maybe there's a different reason.
Does the downgrade apk have to be sideloaded via ADB?

Just place apk in phones working directory, same path where your downloads folder is. Then install from there like any other apk and run. I also kept the FW file in the same directory but I'm not sure if that was necessary.
So, just to confirm, I press "local install" and select the firmware zip and it closes? Is the tool supposed to do anything else or am I good to flash LineageOS?

Ummm if I remember correctly hit local install and then it will prompt to point towards which FW to use. After you hit it, it will go back to the previous screen, I think verify and unpack it, then install it. Mine did appear like it was doing nothing after picking the FW and so I picked again which screwed things up so just wait after picking, it should start.
After its done it will give a message saying to restart phone I think for it to take effect, then after you restart it should ask to wipe phone, then restart again and you'd be in A11 presumably. Once in A11 your good to follow the normal procedure to install Lineage. This is all from memory though so I MAY have missed something but I don't think I did.

Nothing major, caused the UI to glitch out and made it seem like the process was stuck at 81% but when I closed the app and tried to do it again it jumped to 100 and said to restart the device.
I've downgraded a second time (I'm very indecisive on which OS I want to use) and that one went as expected since I knew to give it a second to start doing its thing.

Weird, for me it just closes the app and does nothing, both the official and emergency ones. I even tried adding it to magisk's deny-list.
But I just restored the boot image via magisk (didn't restart) and it works now...

Yes I factory restored the phone and tried again. Still fails every time
Has anybody had any luck figuring out the verification failed message? I too have tried both the official and emergency apps, of course I can't read the actual message in what I presume is Chinese, but it doesn't do anything and the other version says verification failed. Have not rooted. Kind of at a loss right now and all I want to do is install Lineage! I've already got my unlock token from OnePlus, but my understanding is that the phone still needs to be on A11 before installling Lineage.
