bootloop...help? - Xiaomi Redmi Note 7 Questions & Answers

Hi,
Running crdroid, I just updated the firmware. This worked.
I tried downgrading, which resulteded in a bootloop...
However flashing any combination of the correct firmware & OS (including flashing complete miui ROM) results in bootloop on screen redmi by Xiaomi. Only recovery / twrp works.
Would be glad for any suggestions.....

It's a feature of the firmware, if I'm right, It's rollback protection. Sadly, only service employees (and special authorized MiUI account owners) can fix it. FeelsBadMan. It exists to stop retailers from installing custom firmware before purchase.

OK. Got the situation sorted with flashing through fastboot following instructions here (complete flash, link below includes links to tools and proper ROM). Need to completely flash the phone but not to lock :

Guide to switch from Vendor ROM to EU ROM

This is for people who have received their phone with a pre-installed Vendor ROM (MIUI Global Stable 8.0.8.0) and wants to switch to the Unofficial EU ROM. In my opinion, the EU ROM is currently the best ROM without any Chinese bloatware or popups until Xiaomi decides to release an actual Global ROM.
For those who are already on a China Stable ROM, there is already an excellent guide to install TWRP, ROOT, compiled by @underlines. This is only intended for switching from a Vendor ROM as I wasn't able to switch from a Vendor ROM to an official build using the previous guide. You need to be on an official build to be able to use TWRP and flash the EU ROM.
EDIT : The reason why I have mentioned to flash an official build at first is because, TWRP can be unresponsive with some Vendor ROMS. You'll be able to boot TWRP but touch would be frozen. I've tried with both versions of TWRP and it wouldn't work with the Vendor ROM installed on my device. TWRP over the Vendor ROM may work for some users.. For some builds like the one which came installed on my phone, it may not work. If TWRP works for you without being on an official build, you can skip the part where you have to flash an official ROM.
1. You need to have an unlocked bootloader. Please follow instructions on the other guide on how to do this.
2. You need the older version of MiFlash found on this link. Thanks to @Thorin78 for this link.
3. Download and extract fastboot Stable or Dev ROM and extract ROM folder to the C:\ Drive. This is because MiFlash may show a "cannot find file" error if you have a lot of subfolders. To avoid this, its best if the folder is C:\ROM Folder.
4.In the older version of MiFlash, click advanced and change the fastboot script location to the flash_all.bat in your unzipped rom folder.
5.Connect your phone in fastboot mode, click "Refresh" in MiFlash. Once your phone is detected, click "Flash" and it should now successfully flash the official ROM of your choice.
If you wish to be on a Xiaomi Official Stable or Dev ROM, Stop here! If you wish to continue installing the EU ROM proceed with the steps below.
6. Now that you have successfully flashed Official Stable or Dev ROM, use Minimal ADB and flash TWRP RC2 using the instructions in the other guide.
7. Once you are in TWRP, Swipe right to allow System Modifications and copy the forced encryption disabler using MTP. Flash this file to ensure that there are no bootloops.
8. After this step, go to WIPE, Format Storage, type "yes" and then Reboot Recovery. Copy SuperSU and EU ROM to storage and flash. Phone may take a few minutes to boot up and you will successfully boot the EU ROM.
For everything else, please follow the guide posted by underlines.
TWRP EU RC2 works with the China Dev ROM as well. Once you Swipe to Right to allow modifications, don't forget to flash the latest dm-verity and forced encryption disabler script from here. This is to prevent the device going into a bootloop.
These are the steps I followed and I am on EU ROM. Hope this helps people who wish to switch to the EU ROM from the Vendor ROM.

I managed to flash with latest miflash using your guide my bootloader was already unlocked check using:
boot your phone into fastboot and COMMAND PROMPT " fastboot oem device-info "
most are probably unlocked with vendor rom but not all.
Don't try to unlock with this method just check to save sometime.

I guess it also depends on the Vendor ROM and customization which comes installed on your device. Not all Vendor ROMs for this device are the same. I tried everything under the sun with the latest miflash. It would detect device and even give a "success" output but the ROM was never actually flashed. The phone would still be on the Vendor ROM. Its as if some Vendor ROMs have some form of write protection baked in.
I could only get it working with the older miflash.
I'm not saying it was easy, the hard thing was making the unpack ING of the file. Sort of did it twice never had that problem before.

This for people who don't want TWRP, root and dm-verify, just genuine Xiaomi rom with OTA updates and remove vendor rom.
QQ.
I did the following on my Mix and wondering if I am missing anything. I should say that everything "appears" to be working perfectly on the EU rom.
My Mix came with 8.0.8.0 Global (Vendor ROM) and I wanted to move onto the Xiaomi.eu rom. I loosely followed the above guide and did the following steps:
Applied for Unlock
Unlocked the device via MiUnlock
Used Minimal ADB and booted the device into FastBoot
Confirmed device was Bootloader unlocked
Flashed TWRP (latest non-eu build)
Booted to recovery
DID NOT swipe to edit system partition, left that read only
Flashed the latest Weekly Xiaomi.eu build
Wiped Dalvik/Cache
Booted phone
Performed a Factory reset.
All seemed a little too easy and I didnt need to go to an "Official" china ROM first. But I do have a few questions...
Should I have swiped Yes to enter Read/Write mode for the system partition and run a dm-verify? (I am not interested in Rooting the device at this stage)
Should I have performed a System clear in TWRP before installing Xiaomi.eu ontop of the Vendor ROM?

Wouldn't worry about it the vendor ROMs aren't poison, not sure about dm-verify if you kept read only. I would of swiped then flashed dm-verify but didn't mean I know what I'm doing.

This is because some Vendor ROMS have some compatibility issues with TWRP. Touch screen wouldn't work on TWRP. I tried both TWRP versions and couldn't get touch to work.
Finally, I flashed the China Dev ROM and then used TWRP RC2 and touch functionality worked.
As some users below have pointed out that they could get to EU without flashing the one of the official builds, I guess it depends on the amount or type of vendor customizations applied on your device.
Which version do you own? I was wondering if this would work with the 6GB as well.

This works with both versions. The ROM is compatible with both variants as the size of memory and storage doesn't affect compatibility.
I have the 6\256 variant.

Thank you. It worked. I fastboot twrp then factory reset the device and flashed the eu rom. All good. My bootloader was unlocked by the vendor.
Can someone please give me some advice? Just got the phone a couple hours ago. I took a picture of the info page. Based on the screenshot am I on the vendor ROM or official? I'm thinking I'm on Vendor because it has GAPPS already included.
If I'm on Vendor ROM and want to get to rooted EU Rom I can follow directions in the OP right?
How do I know is if my bootloader is already unlocked? Many thanks

Vendor (there is no Global ROM for Mix). You should unlock your bootloader (check if it's already unlocked using "fastboot oem device-info"), flash TWRP, wipe and flash EU

[GUIDE] Error 7 Solution While flashing 7.1.2 ROMs

A brief Intro.
Starting from the 7.1.2 ROMs most of the developers decided to follow the process of checking modem version at the time of flashing the rom. Many peoples ended up in
"Error 7- assert(xiaomi.verify_modem("MSM8976.LA.1.0.c3-30041-STD.PROD-1.77504.1.83742.1") == "1")"
The main reason for this is the outdated firmware or it is happened to those who had unofficially unlocked the bootloader.
Some more info..
1. You must be on MM build bootloader. If you are unofficially unlocked bootloader it will give you ERROR7.
@TheStrix have alreday given a short information about it in his Official LineageOS thread. If you are unaware of it read it here
2.Outdated Firmware.
Your firmware must be from from MIUI Global DEV v7.5.4 or above.
Get MIUI Global DEV v7.5.4 from here
or the latest firmware from here
NB:-
- Iam using the MIUI Global DEV v7.5.4 firmware. All working fine including Volte. I dont know about the second one,you can give it a try.
-If you are unofficially unlocked ,MIUI Global DEV v7.5.4 will re lock your bootloader you will end up in bootloop.
- I will not be reponsible for any damages.
Solution 1 [Permanent Solution] ..
1. So if you are unofficially unlocked, i will suggest to clean flash the latest MIUI Fatboot Rom. Kenzo users get it from here.
2.Flash it using MIFlashTool ,and officially unlock it.
HOW TO UNLOCK THE BOOTLOADER OF REDMI NOTE 3?
PART 1 : REQUESTING FOR UNLOCK PERMISSION
Step 1 – Open up your favorite web browser in your computer (Chrome is recommended) then go to this link
Step 2 – You’ll see the official page of “Unlock Your Mi Device”. Now simply click on the blue “Unlock Now” Button in the middle of the page.
Step 3 – You’ll see a login page in the next page which is in Chinese. If you use Google Chrome to open the page, then you can simply use its built-in Google Translate feature.
Step 4 – Once logged in, you’ll see the Unlock Application Permissions page.Now simply fill in all required fields then click on that green Apply Immediately button.
Step 5 – In the next page, you’ll need to enter a verification code sent to you via SMS. Check your phone for any SMS verification sent by Xiaomi server. The code is usually valid for only 5 minutes so you need to enter it immediately.
Step 6– Once you have submitted the 6 digits code, you’ll then be redirected to another page saying that from the point toward all you need to do is just waiting for Xiaomi Developers to review and approve your application. Once approved, you’ll get another SMS which normally arrives in 15 min(Atleast for me. For some it may take time). The approval process is manual so just be patient on this.
PART 2 : BOOTLOADER UNLOCKING PROCESS
Requirements for Bootloader Unlocking :
-An active Mi account linked to your device, your phone number and it has permission to proceed with bootloader unlock (follow previous steps above)
-Please backup your data for just in case scenario.
-Again, if you are not fully aware of flashing custom ROM, then you better stay away of unlocking your phone’s bootloader.
Download Mi Flash Unlock tool for Windows here, and install it on your computer / PC.
Step 1 – On your device, please login to your Mi account.
Step 2 – Put / reboot your device into bootloader mode. To do that, simply turn off your device, press the Power button and Volume down ( – ) button at the same time.
Step 3 – On your computer, open MiFlash Unlock tool you’ve just installed. Click on the Agree button when asked.
Step 4 – Login to MiFlash Unlock tool with the same Mi Account.
Step 5 – Now connect your phone to computer using its USB cable.
Step 6 – Once your phone is connected, the Unlock button will become active. Next, simply click on the Unlock button to start the process. The unlock process will take about 10 – 15 seconds to complete. That’s all.
After unlocking your phone’s bootloader, you’ll be able to flash TWRP and other custom ROM. Enjoy..
Please take these as your concern upon unlocking bootloader :
One Mi account could only unlock one device within 30 days.
If you see a notice saying that “current user is not logged in connected device” then please reboot your device normally then login with your account in the device (see Step 1).
Unlocking bootloader will wipe all user data especially if your device is encrypted. That’s why you’ll need to create backup before going to proceed.
Neither Xiaomi or I will guaranteed if anything goes wrong during and as the result of unlocking. Proceed with your own risks.
Also, unlocked Xiaomi devices will be marked in the official service end.
PART 3 : Installing TWRP and Custom Rom.
Step 1 –. Get latest TWRP from here. Flash it via fastboot { I will not be explaining that in details}
Step 2 –. Take back up of EFS using Twrp. Wipe Everything including internal storage.
Step 3 –. Install Firmware-Rom-Gapps in order. Error 7 will be solved
Solution 2[Temporary Solution] ..
Only try this method if you are not able to officially unlock your device . Dont use the Firmware by Strix.It will relock your bootloader.
Step1 - Downalod the rom to your pc.
Step2 - Use any notepad. Suggestd one Notepad++. Get it from here
Step3 - Open the Rom.zip{dont extarct}. Navigate to META-INF/com/google/android/updater-script.
Double click on updater-script and open it with notepad++. Edit and remove this line from the file
Code:
assert(xiaomi.verify_modem("MSM8976.LA.1.0.c3-30041-STD.PROD-1.77504.1.83742.1") == "1")
Allow the file to save and close the zip.{Rom will recompress by itself}.
Step4 - Flash in order. Firmware -Rom-Gapps.
Some FAQ's ..
1. Iam not getting volte
Ans:- Restore the EFS. Try rebooting your phone 2 or 3 times. After Clean flash ,I had to reboot 3 times to get volte working. :fingers-crossed:
2.Iam not able to see FingerPrint Option?
Ans:- Your are defenitely on an old Firmware.Update to Latest Firmware It will work.
3.Iam getting Some other Errors. :crying:
Ans:- Post your Screen Shot Below.Will Check.
4.Iam getting some other problems in ROM.
Ans:- Report it with proper logs to the developer.Iam helpless.
5.I bricked my device
Ans:- I will Laugh at you. Always do everything at your own risk. :silly:
Some Advices ..
* At least use search once in your life time. From my observation its clear that no one ever uses search in the Rom Section. Even is there is a solution in every page you keep on asking same questions.
*Dont flood the thread.
*Dont qoute the whole op.
*Respect other members
If this was of help to anyone hit the like :fingers-crossed:

There's a problem with not updating the bootloader (aboot) and staying with a LP bootloader, you will most likely encounter bootloops. Say you edit that code line for the modem check, it will flash but it won't boot/work properly. You must update the bootloader in order to boot newer ROMs. And you need to update the modem and other stuff so you won't face issues. You need to offcially unlock no matter what you do, it's very easy.

you must format your phone (not wipe) using twrp then install fw-rom-gapps...use fw by strix from above method(permanent)
I flashed v8.5.1.0 using MiFlash and it said flash completed successfully. However now it is stuck on the Mi splash screen with "powered by android" logo at the bottom. The dots are moving so I assume it is loading but it's been on that same screen for the past 10 minutes now.
Previously, the bootloader was officially unlocked but some stuff broke as I tried to upgrade to a new ROM and that's why I decided to flash v8.5.1.0 in order to go back to stock and start from scratch.
Edit: It works!

I'm on Marshmallow boot loader (flashed faatboot ROM) and officially unlocked & formated data.
Yesterday I did a update RR ROM (9th july) then I got error 7.
at the time of flashing I was on latest firmware 7.7.6.
So reflashed 7.5.4 firmware and it's worked.
So we should always stick to 7.5.4 firmware ? For avoiding error 7?

yep..in my knowledge the latest firmware has a change in modem version(updated version) so it wont match with one in updater script... so i will say to stick with some older firmware unless the developers chabge it in the roms update-script file...

In theory it should work I guess? Assuming you used the guide from @khajiit here you should have a MarshMellow bootloader, as the MIUI version linked there is based on MM (kate_global_images_6.11.3_20161103.0000.00_6.0_global_16db0fc5fa), so it shouldn't relock. Can't try myself since I unlocked mine recently.

[mini-GUIDE] BRICKED / DOWNGRADE / SAME / UPGRADE - also ALTERNATIVE to RSDlite

I am not responsible for your bricked phone or pigeon poo on your toupe. Do at your own risk.
Many thanks to @SupahCookie for idea and motivation!
INTENTIONALLY DOES --NOT-- LOCK BOOTLOADER!!!
Get factory images here:
https://forum.xda-developers.com/mo...ock-images-t3736767/post75236696#post75236696
THIS GUIDE IS FOR FACTORY/STOCK ROMs - NOT YOUR AVERAGE CUSTOM ROM which may not have bootloaders!!! (thanks!!!!! @echo92 )
FIX:
IF YOU ARE ABLE TO GET TO FASTBOOT THIS SHOULD WORK.
IF YOU HAVE 8.x bootloaders AND ARE DOWNGRADING TO 7, use "Alternative to RSDlite" below.
1 boot to win - 7 or 10 works fine.
2 boot phone to fastboot, and connect phone to computer.
3 start RSDlite
pick a ROM. I believe I used a 7.1.1 rom
3Nov9-ADDISON_NPNS26.118-22-2-8_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip
RSDlite installed it and fixed the problem.
- -
I was then able to use RSDlite to install @rafikowy 's signed 8.0 . - going up from 7 to 8.
- -
- -
If you are on 8.x bootloaders and want to go to 7.x bootloaders, use this (RSDlite throws an error and stops):
ALTERNATIVE TO RSDlite:
1 I used 7zip to extract that 7.1.1 zip (or any ROM zip) into a folder x,
2 add all the adb and fastboot junk to folder x,
3 add the attached file (rename it to flash.bat) to folder x.
4 boot phone to fastboot and connect to computer.
5 click on flash.bat - it throws a lot of "slot" errors but works just fine.
6 reboot your phone if it hasn't already and go through the 7.x install stuffs.
7 you will not show an IMEI if you are coming from an 8.x bootloader. However, it IS there.
NOTE: you may need to add a line to the flash.bat if there are more/less sparsechunk's in your FACTORY/STOCK ROM...
THIS IS NOT FOR CUSTOM ROMs!!!!!!!
EDIT: 3-8-19: I just did this myself to go back very briefly to 7.1 - be sure you don't flash TWRP to it if your going to take OTAs - it will brick it. boot to TWRP if you need TWRP briefly: fastboot boot twrpimg.img
----------
If you can boot to fastboot screen, you can do anything.
Never OTA a ROM if you have modified recovery (TWRP, etc) or if magisk is present.
https://forum.xda-developers.com/mo...p-flashing-t3813498/post77011495#post77011495
I changed the attached file to add pause and reboot and exit to make it slightly more automated.
I have successfully used this many times going back and forth. If you can boot to fastboot screen, you can save your phone and flash anything you want.
You may wish to advise users that if they downgrade to Nougat not to use Nougat OTA updates. The reason being that a downgraded stock Oreo device may still have the Oreo bootloader on it. Thus, attempting to use Nougat OTA updates may hard brick their device (as the bootloader is likely corrupted, meaning no fastboot).
Users could either use the Feb 2018 NPN26.118-22-2-17 firmware from your link https://mirrors.lolinet.com/firmware/moto/addison/official/RETAIL/ as that was the last Nougat firmware (and thus no Nougat OTA updates) or avoid using OTA updates whilst downgraded.

Interesting. I used the above GUIDE to go up and down a number of times on my phone (about 20 total) , installing and running on both 7 and 8, and then went down to a Nov 7.1.1 and let it ota all the way up to 8.0 and that is what I am using now. I found that when i used a factory zip, and the above procedure, it corrected the bootloaders to the appropriate version that i was flashing - either RSDlite or the more manual path which ignores the errors worked for me.
Using the above procedure , you get the correct bootloaders, which are in the zip.
Please correct me if i am wrong!

That's intriguing - we saw previously on Z Play that users downgrading their stock firmware (e.g. https://forum.xda-developers.com/moto-z-play/help/hard-brick-moto-z-play-patch-abril-t3782927 )and then using OTA updates hard bricked their device (hence the number of users asking for a blankflash, as fastboot no longer works). I don't know if these users hard bricked by downgrading their firmware too far and then flashed an OTA radically different to their previous firmware, or whether it's a risk that's taken by any downgrading of firmware.
When you used fastboot, did you see any 'security downgrade errors' when you flashed the bootloader, and is your bootloader version now C180, as you've flashed the Oreo OTA?

YES - that's why I wrote these 3 guides - before, it was quite possible to wind up with a bootloader mix - esp depending on the zip you use! - factory/stock only!!!
I added a line to the guide saying that it is only intended to be used for the factory/stock zips as these have (I believe) the bootloaders appropriate to the ROM.
Many thanks for pursuing this! - I wonder if we'll have to exclude certain ROMs that are in the factory lists?????

If you have TWRP (or I assume any custom recovery) present when you try to ota, it can download just fine and then reboot to the update. I had TWRP and wound up in a situation where my phone would only boot to twrp no matter what I flashed or restored. I booted phone to fastboot, RSDlite'ed that 11-09-17 factory zip and all was well. In that particular case I did not fully install 7.x but immediately RSDlite'ed rafikowy's 8.0 signed stock and went on with my testing. Since then I always boot to TWRP rather than intalling it and do my thing. (thanks @jceballos )

Sorry - since it throws a million errors I never look at it if it works.
The particular build I am on at the moment - is BL: C1.82
This one started from that Nov '17 build and ota'ed all the way to 8.0 Apr.
I root and unroot as needed per rafikowy's method but using a boot to TWRP - never an install TWRP.
I'll put up a new guide ref ota and recovery and brick.

1) If you have TWRP, then using an OTA will fail - as you've not got stock recovery (and likely other modifications, including possibly a system partition set to read-write status). As you noted, having TWRP seems to cause a bootloop when rebooting - I'm not sure if the OTA sets a boot flag to stay in recovery until the update is completed. For the G4/Plus, there's a possible solution by wiping the misc partition but I don't know if there's a similar partition for Z Play devices: https://forum.xda-developers.com/moto-g4/help/troubleshooting-twrp-boot-loop-ota-t3714325
The only other solution I've seen is a clean flash of the stock ROM to get your device booting properly.
Booting to TWRP rather than flashing would mean your stock recovery is still present on your device. The only downside is if you need to make modifications, you'd need your computer to boot to TWRP.
2)BL C1.82 seems to be the bootloader provided by the Oreo April 2018 security patch update, so your device looks to be on the right bootloader. It's still curious that the Nov 2017 firmware worked whereas countless other 'factory' stock ROMs caused hard bricks when downgraded to and then OTA updates were installed.
As you mentioned, custom ROMs don't have bootloaders and thus don't care about your bootloader version usually (though I've seen some ROMs require a certain bootloader). However, stock ROMs and stock OTA updates do have bootloaders, which is why downgrading can be risky.

Downgrading is a piece of cake if you don't use RSDlite - it throws an error and stops. Using the bat file it can happily throw all the errors it wants and all I care is at the end I have what I want.
It does indeed change the entire environment when you bat file the zip contents. You can bat file to get from 8 to 7 and then use RSDlite to flash a different 7 OR 8 zip file. There is no resulting difference in whether you RSDlite it or bat file it - the bat file simply comes from the .xml file that is within the zip. There is very little or no difference between that among addison factory/stock zips. Other zips are different (custom ROMs.)
Grab any factory/stock zip for addison and expand it and you will see modems, bootloaders, indeed absolutely everything you would find on that phone if you went to a store and bought it. SupahCookie simply added a couple lock command lines because it was intended for folks who somehow thought that if phone was locked they could take it back to the store and get their money back. Or some such. I found that ATT folk didn't care if you were on CM or whatever if you just needed to swap SIMs or whatever.
I DON'T want to lock the phone as it prevents me from modifying forever. Oh yeah that reminds me I was going to post the obligatory guide (again) about how to flash a white boot logo so you don't get that message - it's still there LOL but since the font is in white, you can't see it.
I have a Moto Z2 Play and used this to get out of a rather sticky situation.. My IEMI shows 0 now and I'm curious if there's a way to fix this? Also, You say you've done OTA updates? My phone is telling my I have some, is it safe to try?

Thanks for feedback and great on success.
IMEI will show zero if using oreo, It will show again if using N. Remember that if you go from O to N you need to use the "Alternative to RSD" as RSD will simply throw an error and stop.
If you have TWRP and/or Magisk you must get rid of them before ota - if twrp present you will soft brick and have to do alternative again - flash a stock recovery. Simply uninstalling/flash magisk will probably not be enough - it will likely d/l but error part way through update. If you are sitting on rafikowy's stock oreo, and haven't modified it, you should be fine. I know Apr and June are out there. I flashed his stock 8.0 and took June fine. Z2 should be no different though of course I can't guarantee it
If you have success, let us know what you have done so others looking in will know. Thanks!

I actually flashed to this: ALBUS_C_7.1.1_NPS26.118-24_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip Which is a 7.1.1 variant and it is showing 0 when I check settings and when I dial *#06#. However upon connecting to the computer and running mfastboot getvar imei it returned a value. I only did the steps above which would mean I don't have TWRP or Magisk (when I fastboot and click recovery I get "no command")

It had 7.1.1 stock. I rooted it, and then flashed Resurrection Remix (which was yes 8.1 I believe) and the upgraded bootloader. I then found out my service wouldn't work with that.. so I attempted to flash back to stock which gave me a flurry of issues.. eventually getting to nothing but fastboot working. Flashed back to working with your guide to 7.1.1
If it helps in in fastboot it tells me BL: C0.CD

Custom ROMs won't usually update the bootloader (even if they are newer) as stock ROMs typically only have the bootloader firmware.
You could look into flashing the stock Oreo albus 8.0 ROM https://forum.xda-developers.com/z2-play/how-to/fastboot-rom-oreo-retail-via-fastboot-t3786153 or the 8.0 June 2018 firmware https://forum.xda-developers.com/z2-play/how-to/fastboot-rom-albusretail8-0-0opss27-76-t3822195 but please check that firmware has been released for your device variant.
I don't know if updating your baseband to stock Oreo formally may fix your IMEI issue.

"BL: C0.CD" even right after flashing that albus 7.1.1 using "alternative" above?
What happens if you flash one of the oreo roms from the links I gave you above?
Yeah, RR wouldn't change bootloaders... so you upgraded bootloaders independendently?- that could easily lead to a soft brick... -
I read RR on Z2 and it says nothing about bootloaders even though it says 8.1 based, so i wonder if it needs 7.x bootloaders? I did not read entire thread...
In a reverse, I would wonder if you put an 8 on there if you wouldn't see your IMEI. (On the Z if you flash 8 You won't see the IMEI until you return to 7.)(wondering if z2 is reversed)

Yes, right after flashing that is the BL that fastboot is showing me. I don't recall updating the bootloader so to speak, however RR did require an updated variant of twrp which I flashed 3.2.2 I believe to get (unsure if that would have changed the bootloader or not). I also tried flashing a stock Oreo (which you've stated stock Roms usually only have the bootloaders so maybe somewhere during this process I updated it?). I wish I had all the notes for what I did to give more precise information, but I'm in a position where I really need my phone so I kinda just panicked and started flashing things when my service wouldn't work.
I'm highly considering trying to run an OTA (though very afraid of bricking). - On a side note though, it wouldn't even tell me I had OTA's until I did the steps in the original post here (doing the different 7.1.1. and 8.0 flashes, it wouldn't ever tell me I had updates, and now it does).
*** Edit ***
Looks like I'm able to enter stock recovery, which makes me believe everything is stock at the moment.

If you flashed a stock O that would have changed bl to O, but doing the above with the stock 7.1.1 would have changed them back to N. No matter (other than academic) that you don't remember the path - flashing a stock anything reverts it to that point in time. However, IMEI may have been moved - don't know. It will likely show on EITHER 7.x or 8.x stock - just don't know which.
If you flash a stock 8.x from those links I gave you above, it should offer you ota, ASSUMING there are any at this point in time(Z has 2). Adding Magisk at any point seems to hose you for receiving any more ota's - don't understand why, even with magisk uninstall, so that would mean going back to the latest stock and losing what you have (which is why I try to take a TBPro and copy that backup to PC (because re-flashing 8.x stock will likely reset internal storage.).
yes, if you enter stock recovery, you are likely at stock, though you could reflash the latest 7 or 8 stock to be sure, depending on which you want to use as base. Since 8 is having security fixes released, I choose 8 and will likely have no more interest (no time!) in 7.
So, ran the OTA and it was fine running the update and staying on N. I also downloaded the OTA for Oreo, when trying to update the recovery error'd out. It looked like the error said "Error in modem unexpected results" or something similar.

did it offer to let you d/l it again? you could try that.
However, there exist O stock zips in those links I gave you so you could just flash the latest...

Oreo 8.1 Update T585XXU4CRJ8 problems

Hello all
I installed the latest T585XXU4CRJ8 Oreo 8.1 update over Nougat 7 on the SM-T585. (BTU / UK)
Everything went well using Odin and the Oreo stock rom from the Updato website.
Cleared the cache and factory reset from recovery mode as normal practice. Booted up ok.
The problem is the device doesn't recognise the network sim card anymore (worked perfectly on Marshmallow & Nougat).
I've tried factory reset a few times, no difference.
Removed and reinserted the sim, even tried another sim.
Having checked 'about tablet > software details' , carrier is unknown and the IMEI has dissapeared !
I've tried to reinstall Nougat 7 and Marshmallow 6 back on the SM-T585 and Odin fails every time.
Tried 2 computers and 3 different usb cables.
Even trying to reinstall Oreo 8.1 again Odin fails!
Theres no frp lock activated, and the oem unlock tab is checked, usb debugging enabled too.
I've read somewhere Samsung have done something to Oreos BootLoader file to stop people downgrading back to earlier software.
I know its early days, but if anyone can offer any solutions, it'd be appreciated.:good:
How to change the BL file version, so i can reinstall earlier stock roms back?
The Oreo update seems more hassle than its worth and I didnt expect the sim card to be unrecognised once updated, let alone being faced with the puzzle of how to downgrade the software.
Thanks for reading. :good:
I think the problem was I used all four files (AP, BL,CP & CSC) from the Netherlands rom and that's whats screwed the device up!
As in no SIM card acknowledgement. I ran the IMEI number off the rear casing through a blacklist checking site and it came back clean.
After many attempts trying every Odin program variant possible and even tried mixing and matching files from different stock roms ( MM 6.0.1 , N7 and Oreo 8.1). To try and get the network carrier file installed, Odin refused to install anything.

https://download.chainfire.eu/1069/CF-Root/CF-Auto-Root/CF-Auto-Root-gtaxllte-gtaxlltexx-smt585.zip
https://twrp.me/samsung/samsunggalaxytaba101wifi2016.html
Tried the above routes to root to no avail, but Magisk worked by patching the boot.img file (which worked ok). Then tried Odin to install TWRP recovery, again from the site above, nothing but blue and fuzzy lines on the boot screen. The device wouldn't boot into the OS, had to go straight to download mode. Prior to that, I even installed the TWRP manager apk and connected to wifi to flash the TWRP.img from inside the OS environment and the same happened again with all variants of TWRP! Wouldn't boot, properly, no screen visuals, but lines......
Surely someone else on here has the same device (BTU UK) SM T585 that has a working TWRP recovery?
After many hours, I couldn't get Odin to play ball , so the only option left was to try the route of root, twrp recovery then installing a custom rom from twrp.
(https://forum.xda-developers.com/ga...-ultra-lean-rom-galaxy-tab-10-1-2016-t3467942)
But it's a no go as TWRP wouldn't install properly, I'm totally miffed by the damage the software has done.
Surely just reflashing the CP file should have reinstated the network facility, but it hasn't.
The last resort is for me to wait until Samsung actually release the UK version of Oreo 8.1 and see if I can get the sim card working again.
Moral of the story is wait until a UK version of the update is released, and even then you have to question is it worth it, if Samsung are making bootloader files so no downgrades are possible, nor allowing any modifications.
Hopefully this info may help others out who are thinking of upgrading or having similar issues.
Cheers for reading

I had the same problem, went from Lineage 14.1 to Oreo stock rom (the flashable one you can find on this site, i flashed also the Bootloader/modem file in the thread). No imei, no baseband. Returned back to lineage and got back imei and baseband, but after my screen was going to sleep (after the regular 1 min) I had only black screen and vertical red lines. I flashed then Resurrection Remix 6.2, Lineage 15, Lineage 16, always the same problem. Then I used Odin and the original firmware of Nougat from SamMobile, at the first attempt i flashed only the AP file. I turned to have the same problem, but this time the lines were white. I flashed all the 4 files again with Odin, problem solved and back to Lineage 14.1 (the only custom rom were everything works)

What version of TWRP have you installed for the T585 and from what site?
Also what root method did you use?
I have tried all available and all seem corrupt i.e don't install properly, no proper boot up with onscreen options. Just fuzzy lines.
Again root i've tried many, but don't work with this Oreo 8.1., even Magisk is problematic.
I think its pretty sad of Samsung sending out poor quality updates for us to use. Their heading the same way as Apple and the way they control customers.
If I could go back to a custom MM or Nougat, I would. But TWRP / ROOT are an issue. i.e no TWRP no custom rom!
If anyones thinking of updating and reading this topic, stay clear of the Oreo 8.1 update for the SM T585. Once installed theres no turning back.....so it seems
Thanks for replying.

just flash the nougat firmware from SamMobile. You have to flash all the 4 files in the zip you are going to download. AP, CSC, etc. Once you have your tablet completely stock you can install again TWRP and flash whatever CUSTOM rom you want.
I easily rooted the phone with odin flashing only the TWRP in AP box (twrp taken from this post https://forum.xda-developers.com/showpost.php?p=78145080&postcount=160) avoid the auto-reboot. You have to put the tab in DL mode, connect it to pc, start odin flash the twrp in AP file e unselect Auto-reboot. As soon as the process is done you have to log in recovery mode at the first boot with home + power + vol up and flash dm-verity. I rooted with Magisk without any problem just flashing the v17.3. Now i' m back to nougat (from Oreo) and i can install whatever custom rom i want. But honestly the only one fully working is Lineage 14.1. Resurrection remix 6.2 has problem with camera and gps don't lock. Same for Oreo version. Tried Pie, same problem.

Thanks for the info.
I tried to install MM 6.01 & Nougat 7 stock rom and they wouldn't install, no matter what I did. ( see Odin pictures )
The last chance was to try Oreo 8.1 again and I did manage to reflash the 'Netherlands stock Oreo 8.1 rom' (after 10 hours!) using all four files (AP,BL,CP,CSC).
I then reset the device a couple of times via stock recovery. Took the OEM lock off, theres no FRP lock either. Enabled developer mode > debug mode (all the usual setting changes prior to rooting / twrp install).
At this point the imei and sim card network ARE recognised and work on the device as normal.
HOWEVER I found once I rooted by any genuine means > Magisk v16 (patched boot img taken from stock rom) and also the CF gtaxlltex sm t585 auto root method.
And when the device booted back up, the 'imei and sim card' WERE NOT usable, nor recognised, no network...........I also noticed BusyBox wouldn't install at all, message about integrity of root.
Adaway and Lucky Patcher recognised root.
I also then tried installing TWRP 3.0.2.0 -3.2.3.0 from many locations and again, none of them worked at all. Just blue lines, fuzzy screen etc. On some occasions Odin wouldn't even process the files.
I include pictures of the files I used.
Its evident to me that I can use the device normally i.e sim card , make calls, data etc if I don't attempt to install root / twrp recovery.
So no root , no twrp , then no custom rom usable or installable. It sounds like Samsung are out to stop custom software on their products.
If the Netherlands stock rom 'BL' (boot loader) file is encrypted with this new binary v3 or v4 to stop OS modifications. I wouldn't recommend using it when flashing the new Oreo 8.1 rom or future new releases.
The best way is to just use the AP file ONLY and overlap Nougat 7 or MM 6. And because you've kept your original BL from earlier stock roms, it may be possible to downgrade back to MM or Nougat if need be.
Once the latest new Oreo / Pie 'BL files' are used in the Odin flashing process, it causes big problems.
Hopefully, maybe someone smart enough can find away to decipher these new BL files and offer a replacement method. which will allow software downgrades and modifications

Honestly i think this run for Oreo it's not really worth. I said you what I did and now i have no problems. I'm not in hurry to use Oreo (as stock rom). I think Lineage 14.1 is the most stable and fastest rom i tried till now, and most of all everything is working. I think i'll give a try via Odin to the official stock rom when it will be available for download (i live in Germany) but sadly I don't use most of the Samsung bloatware installed by default.
WRP Oreo 8.1 on Galaxy Tab 10.1 (T585)
Then I've tried
twrp_3.2.3-1_sm-t585_29918 which gives only stripes when booting into recovery
Do I have to flash the stock boot/recovery before flashing this one,
or this is broken, as well.
Many thanks for a hint,
Helmut
Hope this helps.
So, as I was trying to search for my Galaxy Tab A6 (SM-T585) for Deodexed Stock ROM, I stumbled upon this thread https://forum.xda-developers.com/galaxy-tab-a/themes/mod-twrp-odin-t3650215 just follow the instructions to fully flash Oreo. By the way when flashing Root, I would recommend Magisk Beta https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
it does not damage the IMEI at all(Thread here, read the comment:https: //forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445) . The TWRP, I think we should leave it be, don't flash an update for the TWRP.
Thanks. Hope this helps.

Neither does a custom recovery, so not sure what your point is?
I mean if your having problems using MAGISK use the beta version

Update phone with unlocked bootloader

Short question first: is it possible to update an unlocked p10 lite without loosing data?
Flashing this phone is really hell! I have some flashing experience and faced a lot of problems before but this is really nasty!
However, for those still trying, here's what I've learned (the hard way):
Most important: before you do anything, check your current firmware version and model and write it down! Also write down your EMEI E.g. flashing a ...C432... firmware (EU unbranded) over a ...C02... (vodafone branded) will not work! Re-branding / de-branding didn't work for me - I tried different ways but didn't succeed. You can use Huawei Download Tool to get firmwares. Always double check the versions!
Also backup your data! After flashing TWRP, the first thing you should do is backup to an sd-card - especially oeminfo, vendor and cust partitions in case something goes wrong! Copy the backup from the sd to your pc!
Flashing a custom rom like LineageOS seems only to work with unbranded version and after upgrading to latest major stock rom version.
Don't know if unlocking works with EMUI 8 (Android 8 - Oreo), I followed the tutorial and downgraded to EMUI 5 (Android 7 - Nougat) first
To get the unlock code I paid 4€ to get 4 credits in dc-unlocker. I'd say its worth it because it just works and takes not too much time
If you managed to get an unlocked EMUI 5 and want to update to 8, you have to consider a few things:
Partitions are different in both versions. E.g. flashing TWRP via fastboot is fastboot flash recovery ... with EMUI 5 but it's fastboot flash recovery_ramdisk ... with EMUI 8 so pick the right tutorials!
The easyest ways to flash at this point is either flashing by dload method or by HWOTA tool.
For dload method, read the tutorials carefully! If you do it by the dload folder on sd-card, you have to use a service rom! These are special stock roms which are different from the regular (full) rom images.
HWOTA tool also offers dload method updates - here you can use regular (full) roms like those from Huawei Download Tool
The other method in HWOTA tool uses fastboot / adb to flash. Don't know the pros / cons of both methods but either should work
If your phone doesn't boot / loops, make a factory reset / full wipe after flashing!
If your system version is 8.0.0.046 you picked the wrong firmware (see first point "most important"). Download the right one and re-flash
I finally got a (vodafone branded) Oreo running (didn't check if everything works though). I wanted to flash LOS in the first place but it seems branded phones don't work with LOS. Now I'm glad the stock rom is working again so I consider sticking to it but that's where the initial question comes up: can I simply fastboot flash system ... to update and keep all data?
