Downgrade from CAN-L11C432B320 (EMUI5/7.0) to CAN-L11C432B100 (EMUI4.1/6.0)

hey community
I've tested CAN-L11C432B320 a while and miss the equalizer-app, also have an extreme powersaving device (...) but if i'm running runtastic they will turn off gps after 30 seconds display-off-time, background-services like whatsapp, pushbullet, etc.. will close after a few hours "inactivity", bad fingerprint-performace, some xposed-plugins have massive battery-drain and wont work....
so on.. i still search a while if its possible to get my stock emui 4.1 back...
...and yesterday i found this post:
h**p://w*w.htcmania.com/showthread.php?p=24388723
it looks like there was a full CAN-L11C432B100 and CAN-L01C432B100 firmware but i could not install them
i put the update.app in SDCARD:\dload and tried to install them with original EMUI5-recovery and the extracted EMUI4.1-recovery - everytime it hangs up at 5% and reboots after ~5 minutes.
i'm clueless.. maybe someone will also downgrade and found a solution how to get them work...
sorry from my bad english and the link-modification but i'm new here

I think we need to flash first the EMUI 4.1 recovery.img

There is a link for a rollback update, but i'm not home. When I get there, I send it. About battery, try to use greenify to help it to last long.
You can't just try to use a full package because of versioning scheme they use.

Here http://update.hicloud.com:8180/TDS/data/files/p3/s15/G79/g0/v72696/f1/full/update.zip

Same problem here, still drops at 5% even with the new file
I just wana know the best way to revert to stock

thanks for the file but it won't work for me too..
the install process stops at 5% "Installing update" and reboots after a few minutes

can we extract all from the ota update zip and install via flash? can this work?

Hmmm, sorry, I thought it would help. In fact, the package is listed as a rollback to M, but it is for CAN-L11. The rollback for CAN-L01, I didn't find. As there isn't many differences between those models, I thought it would work
EDIT: now that I read the op again, I noticed that your model is CAN-L11. I wonder why it didn't work

No, it won't.
The reason behind this is because system partition get smaller (because nougat way of update) after updating it to emui 5. So the old system.img won't fit the new partition

My phone only hangs up at 5% when the usb cable is connected. When i open the download mode without connected usb cable, it works.

Is a restore of a CAN-L11 backup from Android 6 in TWRP not possible?

no, in my opinion the nougat bootloader want work with mm.
I would flash the firmeware of mm and after that flash twrp and restore the backup after that [emoji106]

It will work. There is a backup within twrp thread, from bluesmothie.

Did the same thing, but first TWRP didn't find the backup. So i did a small backup just of the boot partition, so that TWRP makes a new backupfolder "FPF4C16A07000014"". Now i renamed the " FPFDU16930014596" to the new "FPF4C16A07000014" and TWRP found the backup and i was able to restore :highfive::highfive:
Small Addition:
It was a freaking fight to get my bootloader unlocked again, cause i lost the unlock code.
The websites (english and asian) are freaking BS. Was not able to get to the page where you get the code, so i downloaded DC-Tool and payed 4 dollars for the damn code.
Now the code is saved in my owncloud, dropbox, google drive, on a sheet of paper and google notes. No way to lose it again
B100 firmware is much smoother than B320 but has a lack of comfort, like i'm missing the new quick settings with double pull down and the touch responsibility of slide bars (like the volume bars) is not very good in B100... But i won't upgrade to 320 again, because of the following points that make it a no go for daily driver:
- Camera is very slow and hangs up
- Video playback is very slow and buggy (no matter if it's in the galery or youtube, ect.)
- Fingerprint is too slow
- Whole system gets very slw if you dont clean up the app history
Will upgrade again when there is a new version out

please am having same issue here. tried restore but still not booting.
problem is cust. what do i do about it.
HELP ME

Problem: Bootloop and "software install failed"

Hello,
hopefully you can help me with my seemingly bricked Honor Pro 8 because of root and stock rom update procedures. I bought the phone with amazon and the package seemes to give me the information to have an EU-version of the phone.
The fastboot get-oem-information code or so also puts out the status of an European bootloader.
Regarding my working steps first of all the phone took the new update. Then I was successful in unlocking the bootloader, installing TWRP and rooting it by supersu.
But after that I was curious about the "Magisk" rooting abilities. Therefore I tried a superuser-unroot via script finding inside this forum following by flashing a extracted boot.img of an update.app file of a DUK-L09C432B130 update. After ending in a bootloop by trying the 1.30 beta version of magisk I was able to boot the normal android desktop after I uninstalled the beta version and having flashed the normal 1.20 version.
But then I tried to install 2 certain modules inside of magisk. In consequence the problem was to see the rebooted android not to load any icons. In the other side it put up the message of not having enough mobile disk memory after some minutes which couldn't be true in fact. So I tried a factory reset inside TWRP and also a full wipe. Disappointingly I haven't been successful in rebooting android once more.
Therefore I unseccessfully tried to flash the Full-OTA-MF stock rom of DUK-L09C432B130 in two versions and the L09-C432b120a via the EMUI-install mode by pressing vol+ and - and power buttons. To do that I prepared a SD card as a exfat format. But I just received the message of "software install failed" when reaching 5 %.
So I got to the frustrating point not to know what stock rom I can flash in another try or doing anything else. I would be very glad if U could help me in this desperating situation. :fingers-crossed:
Thanks and best regards.

you download the nocheck recoveries from my rebranding guide, download the corresponding firmware by morph (important!), flash both recovery images just like stated in the guide, boot into recovery mode like you would do to boot into twrp, do a factory reset, reboot and insert the microsd with the dload folder from extracted downloaded firmware and boot into force dload mode (vol+ and vol- and power) - the installation should start now and reset everything back to full stock.
Regards

Thank you very much OldDroid. You're my hero. It worked fine.
But to install the new 130-update the phone starts inside TWRP and ends with an "error 9" and the words "block image verify", "asserts failed". Could it be possible to perform the update by starting the forced update process by pressing the three hardware buttons on booting? And is it possible not to wipe the data and losing root by using a update?
Viele Grüße aus Berlin nach Berlin

OTA packages cannot be installed via twrp at the moment
you should use stock recovery for that!

Could you explain me a bit more please? Is it the standard system update ins the systems menu, here it wants to load the 2,9 GB file. Updating this way with the "no check recovery" resulted in an checking error at about 12 %.
Or could it be via recovery shortly after starting the phone? But there are no choices to choice. It just automaticely begins installing something stopping at 5 %.
Hope you can help one more please.

soooo, if you flashed one of @-=MoRpH=- 's firmwares, your device is back to stock and the recoveries have been overwritten again! I don't recommend flashing OTA updates or other things through the NoCheck version as it is only intended for worst-case cenarios.

But could you tell me the single steps to update from Morph's DUK-L09C432B120 version to the newest version DUK-L09C432B130?
I only got errors to update the firmware DUK-L09C432B130 from the stock rom thread in this forum and the russian website mentioned there.

Moto z problems

Phone - Moto Z play XT1635-02-DS
Android- 7.1.2
Installed TWRP 3.1.1.0
Viper addison 7.1.2
Here are my problem:
1. Flashed with supersu v2.79 and also v2.82, neither works. Phone still not rooted. When i tried toa access supersu app, it says "there is no su binary installed and supersu can't install it..."
2. Camera does open but it doesn't function, it stays dark. (I have custom gapps 7.1.x)
3. Proximity sensor does not seem to be working in other cases, but the phone goes dark as soon as i press dial or as soon as i pick a call and remains so untill the other party cuts the call. Otherwise i need to shut down the phone if i have to end the call from my phone.
4. When i shut down the phone, in order to reboot manually from recovery-reboot-bootloader. Otherwise it remains in twrp recovery.
Can anyone help please?

Have you tried flashing back to stock and seeing if that fixed these issues?

This is not really a problem with the phone per se but the rom you chose to flash. The reboot issue can be checked by setting a command at bootloader using "fastboot oem fb_mode_clear".

Thanks for your concern. Developer option is 'on' and Multiprocess webView renderers seperately - 'on'. But i get the same problem. (and how do you attach screenshots ? I don't see any option for attaching files) In anycase, like you said, i think the problem has more to do with the rom. Can you please suggest me another rom or if possible link from where i can download stock rom for my phone.

If your on xda with your browser, it's the paperclip icon to attach files. If you are using a 3rd party app that wraps xda into it then I can't help you there. As for going back to stock, Motorola made things a little critical when they released Nougat. Depending on how far you were on keeping the device up to date through stock, flashing the available stock images (which aren't signed) could brick the device if you aren't careful. There use to be an account on androidfilehost that uploaded current stock packages but it seems they're all gone now. If you remember the build number of the device before you rooted, that will help in picking the right stock files. I've taken a break in keeping my device rooted so I haven't kept track of the resources used to help go back to stock but they're in the MZP guide threads.
EDIT: a word of caution when reverting to stock:
-Don't use flash tools that don't let you see/edit the fastboot commands
-Do not use commands that touch modem/radio or gpt partitions
Found an upload of the latest build release keep it around when you figure out what you need to flash. It's best to clear system, data, and cache before flashing. Also have a rom (and twrp) at hand to adb sideload in case stock doesn't boot.

Just saw that the first Miui 12 from xiaomi.eu for many devices is out. Quite exited and going to install it.

I'm sure there are videos out there but it's actually not relatively difficult:
Unlock bootloader (Google Xiaomi bootloader unlock, it's an official thing Xiaomi offers) [THIS WILL COMPLETELY WIPE YOUR PHONE]
Install TWRP custom recovery (you can find guides on this forum)
Boot to TWRP
Go to Wipe > Factory Reset & Format Data (if coming from a non-Xiaomi.eu ROM)
Copy Xiaomi.eu ROM (from https://xiaomi.eu/community/threads/20-5-14.55760/) for the Mix 3 to internal storage
Go to Install > Flash ROM you just copied
(Not sure if this is necessary but I did it to be safe) Back > Wipe > Format data again
[Optional] Go Back > Reboot > Recovery to boot back into TWRP (you NEED to do this before attempting to flash Magisk, not entirely sure why but it will bootloop otherwise) > Install > Flash compatible Magisk .zip for root access
Reboot > System

Just flashed Xiaomi.eu MIUI 12 beta 20.05.14 and it runs like a charm. They changed up the way permissions are granted so all my apps are prompting to reallow certain things but that's nbd. Also you can turn off the new iPhone-ripoff notification shade thank god

Tnx for reply, I will apply for bootloader unlock, and check out this steps. Some follow up questions, i see you put the link to "weekly" rom, does than mean it will be updated every week, and is there some sort of "stable" version that gets update monthly or something like that, and also does Xeu get OTA updates, is that possible, or its always done with PC? tnx

Actually yes we have stable version. However since MIUI 12 isn't officially go global for Mix 3 (yet) then these versions are being made based on alpha/beta once let's say

Yes it is a beta ROM that's updated weekly. There is a stable global version of MIUI 11 (Android 10), but a stable MIUI 12 hasn't been released for the Mix 3 yet. Should come eventually though. I update weekly through TWRP, it's not exactly as easy as an OTA update but it only takes a few minutes at most and you don't need a computer to update.
If you're going to go with the weekly beta, I suggest the 20.2.27 update (it's MIUI 11) because it felt the most stable. Didn't find any animation hitches or weird issues or anything. The latest MIUI 12 beta is good too but the animations are a little wonky at times.

On the latest changelog, it says the beta will end for Mi Mix 3 from September 5th. Does it mean EOL for Mi Mix 3 or only stable builds will be updated?

in version 11 I had a problem with the sensor during a phone call. it turned off the screen but didn't turn it on.
in version 12 there is this problem too. Do you have that too?

STOCK BASED ROMS LIKE BEYONDROM WILL ALSO NOT WORK!
PLEASE NOTE:
-I am not responsible for a bricked device, please make backups and make sure to
always have the official firmware if something goes wrong
-flashing this requires you to factory reset your phone or else the phone won't boot
Instructions:
-unlock your phone's bootloader
-boot into download mode
-in Odin uncheck auto-reboot
-put the .tar file into the AP slot (If it doesn't work try USERDATA)
-after flashing boot into recovery with the key combination
-select factory reset and confirm (This will wipe everything from your phone)
-after factory reset reboot into system
-setup the phone and restore your backup (if you made one)
-Install Magisk and you're good!
If you have any problems
Please don't just comment "Doesn't work" and instead tell me about
the errors you encountered, your software info and other information
you think would be helpful.
Happy flashing!
If you still have questions make sure to ask them below

Geeeeeez! Update your phone! You have to have OneUI 2.5 BTJ3 or OneUI 3.0 CTL1 at least. What are you doing on 2.1? If you don't update, this will break your phone.

Okay buddy,ty..will do that.

Depends on the version. I don't want to be rude but how did you even manage to root your phone with this lack of knowledge?
If you update to Android 11/One UI 3.0 you chose the One UI 3.0 one. If you only update to 2.5 you chose 2.5. Remember to check the end of your firmware number:
There are supported firmware endings:
One UI 2.5:
-BTJ3
-BTJ4
One UI 3.0:
-CTL1
-CTL6
-Any One UI 3.0 firmware above that.
Download SM-G988B / Galaxy S20 Ultra 5G SM-G988B in Samfw - Samsung firmware download
Pick your CSC there, chose the newest one preferably (A11), press "Download on website", unzip it and flash it with Odin while in download mode. You should know how to do that.
After it's finished, complete setup (do not restore any backups yet!) and go into download mode again. Flash the file as AP or USERDATA (whatever works) and perform another factory reset. Done.

So i just reflashed stock because Beyond rom is givving me issues, says you removed all the BS from the boot screens but i still have that unlocked bootloader msg. i flashed in AP with no issues, that msg mean it didnt work?

Ok disabled the autocorrection. What I was trying to say is: The unlocked bootloader message is still there just without the bull**** about your phone being vulnerable to hackers and this other ****. It now just says that it is unlocked.

That can't be an issue with the script as it doesn't modify anything related to the camera

Short answer: Yes
Long answer: You are unlocking your bootloader and flashing a custom image so you lose your warranty and trip knox
