[FIX]Marshmallow BOOTLOOP

OK people, so i bring another (hopefuly helpful to someone) exprecience with BOOTLOOP.
Problem: I had stock B200 firmware (5.0.2). I wanted to try beta update of marshmallow, so i decided to try it. It was told me i can update directly from B200 one, so i just copied update.zip to DLOAD folder, went to settings and run local update. The phone restarted, booted into recovery and started flashing. BUT, i forgot that i had custom TWRP recovery and not stock one, anyway, TWRP started flashing the zip, error after error, but some files still copied and bricked the phone. I couldnt start any recovery, just fastboot and some mode that should download online file and reflash system, but it would be very easy so it has error too.
Here is what i did:
1. Download the update zip of marshmallow you were trying to flash and unpack UPDATE.APP
2. Extrac: RECOVERY.img and BOOT.img
3. set phone to fastboot mode and flash extracted BOOT.img, then RECOVERY.img
4. after that, you need somehow copy whole B200 firmware into sdcard / dload folder (i took micro sd and inserted into another phone, then copied it)
5. now you can boot into force flashing mode (power + volume up + volume down buttons) and it automaticaly reflash whole system.
6. after reboot you can use your P8

OK, i got it work!

I did exactly the same mistake as you and the same steps to fix it. I flashed those 2, places the update.app + the other files to dload and then 3 button update and I got to the huawei music and animation. Then it restarted.
mega:///#!IEhCRaRR!GT6Ds9EywDoW5Dd8ZdKVesyQUItbiSwCPaapFhAenEY

Is there any advice you could give?

then try to flash rollback, the CUST.img is very important to flash

If you are on 5.0.1 with root and twrp then you are good, or do you want try BETA? if yes then you need stock recovery flash before flashing beta

I've tried this,albeit without the userdata.img however although it took me back to EMUI 3.1 and Lollipop some menu items were not working such as setting a screen lock and unable to get to guest mode.
Would also not update using the B114 full ROM, would only accept the B303 beta.

The path is c:\.....where you extracted........ and the update.app must be a full rom not ota update

Ive tried flashing the recovery.img, boot.img, cust.img and system.img from B145, then factory reset and then restoring a TRWP backup of B114 however it still doesn't work, still cannot access lock screen settings (and fingerprint settings) or security settings.

After I flashed the .img files from a b114 ROM I tried restoring my backup however it failed so I had to restore my b303 backup

Rollback
We work here in the German Forum (Android Hilfe) for weeks to find a solution. The rollback is not yet possible.

There is rollback package on polish site: http://consumer.huawei.com/pl/support/mobile-phones/mates-pl-sup.htm
But after I did that it switched do C900.

Honor 5c L21 aka 7 lite

I update to B132 and I have some bug on this firmware
https://www.youtube.com/watch?v=1yVya1LV5IM
https://www.youtube.com/watch?v=-Mhg3hdcSq0
I want to dowgrade from nem-l21_c432b132 back to stock nem-l21_c432b100
I copy the dload and update.app B100 + *#*#2846579#*#* and press update, but is not working, i get update failed.
How can downgrade the firmware?

You got the update fail cause your version is higher than b100.
I think that if you want to downgrade you will have to download Full B100 not the OTA.
But I recommend if you want to do this use the b130 - I am using it and it is very good.
Do the whole procedurę through turned of phone: then VOL down and up together if I remember correctly.

I have try Full B100 not ota.
Not working.
Maybe some one know how to downgrade with fastboot?
nem-l21_c432b132 to nem-l21_c432b130 is working downgrade.
But i want nem-l21_c432b100

i try flashboot
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cust cust.img
fastboot flash system system.img
At fastboot flash system system.img i get failed
someone can help me?

@zzhunt This is an experimental method to go back to B100 by using OEMinfo. You do on your own risk! Required unlocked bootloader and installed TWRP (from Meticulus). Before performing make a full backup in TWRP.
1. Download here this package and put together of firmware B100 on the memory card,
2. Run and install in TWRP this package.
3. When finished install it, restart your smartphone to fastboot mode (Reboot>Bootloader)
4. Plug it into your computer and flash original recovery [LINK] a command "fastboot flash recovery recovery.img"
5. When you can flashed, then disconnect and hold power switch. When the informations will disappear from the display, immediately press the buttons Volume up and Volume down,
6. Will start the flashing system and after finishing restart your smartphone
7. Done!
I tested so far only on my device and don't know, what will happen with smartphone a different serial number/IMEI etc., but rather it should go.

Reverting back can be done by putting the full update in dload folder in sdcard. I have once got that error that u r talking about after the installing process completed. So i simply rebooted. And i got the stock one. So try this, just reboot and see.

In full stock firmware, after extracting it, there is dload folder. In dload folder there will be 2 folders and update app.

I try B100 firmware bulgaria and greece
On greece is only dload folder and update.app
And in bulgaria is 1 folder hw + update.app
http://postimg.org/image/w6e41dxet/
in hw folder is other folder EU and inside is update_data_hw_eu.app
I try with update.app + this folder.
Not working, at 5% fail install and start normal.

I want to go back to B100 because this updates B130-131-132 is junk for me.
Only problems i have

You have unlocked bootloader? If not, you'll have to unlock - here is a tutorial on how to do it. Then you flash TWRP and perform what I wrote previously.

for me b132 optimized alot battery life and ram usage. also gpu works better.

[TIPS] Revert Custom Rom to Official and untouched - Hard restore

Hi!
I see the large number of requests concerning the roolback of a custom rom to a official and untouched EMUI 4, i decide to create this thread.
After follow that methode, you able to rest on official EMUI and get the new update automatically on OTA (directly on your phone) OR try to install custom rom with a clear and good base version.
1. You ave access on TWRP?
-If not, pleas unlock your bootloader (again) and flash TWRP recovery for you actual version (marshmallow or nougat).
-perform a full wipe and restore your partitions on "ext4" format, shutdown phone.
2. Get a "oem_info.zip" for your model phone (dont extract the .zip) and push it on your internal or external sd.
-This archive contain cust and oem info for patched your phone at the correct manufacture information.
-I have a link for VNS-L31 (c432, but is not very important) HERE LINK
-If you have other model (VNS-L31) pleas find a correct patch for you (VNS-L21, ...).
3. Find and download a EMUI marshmallow official full-ota update.
-for a VNS-L31 i advice choice a VNS-L31C432B160 full-ota update.
4. Unpack your update archive.
5. Create "dload" folder on your internal or external sd and put it UPDATE.APP
6. Reboot phone on TWRP recovery and flash "oem_info.zip"
7. Use dload methode for update (hold 3 buttons phone and dont release before "dload screen" appears)
8. Unlock your bootloader again (important!) And make a factory reset
9. Your phone reboot (please wait ) and done!
Ok now you are on official version, please update on setting menu >> update and choice, rest on official or flash a custom rom..
P9 lite brick precision:
In my personal experience the "p9 lite" is very easy to flash, mod or other tips and the risk of HARD brick is very very tiny.
If you see this page and your phone bootloop, relax, keep calm at 99,999% you have a little and ridiculous brick
Good luck and flash happy!

Update: I can now reach point 7 but now won't do dload (3 buttons) method... Huawei logo all the time. Can't even turn off the phone

In my other thread you post the same problem but is not entirely the same..
You succeeded to enter on fastboot mode? Flash recovery?
If you follow the steps 1-5 is impossible to fail the 6 point..
You have acces on fastboot mode or not?..

Now I can't do dload method, stuck on huawei logo. If I try to go to recovery, I got red message "phone fail validation"...
I know, I post on both but I was trying to do everything...
just tried... validation red error message won't let me go to TWRP now...

You have a VNS-L31C432?

Wipe all partitions an retry flash a oeminfo for your model phone (if not C432 you need right oeminfo).

How can I wipe all partitions if stuck in Huawei logo? Is there a way to do everything from adb command line? (I'm using Mac and cannot use all the tools I've found here XDA neither hiSuite which is basically a backup photo/video only the Mac version).
Thank for helping, really appreciate
To answer your question in the other thread, yes bootloader is unlocked and I am on C432.

What's your rom have before the bootloop?
You have the right version of TWRP for your rom?
If you have a MM version Don't flash a TWRP for N.
Send me a link to TWRP version used (thread forum)

Before the bootloop I was on L31C900 (on the phone) but I did actually flashed C432B160 because I did rollback. TWRP used I've found in the other post where there's a OEMfile to flash (but for this I need to double check because I did look so many pages which I am not 100% sure.

I not have experience on other model that C435.
But i suggest to find a oeminfo for your variant (C900?)
For TWRP you need flash a version for MarshMallow HERE
Flash it and pas return here (fastboot flash return and first enter to new recovery)

Hi, found Windows emulator for MacOs so I extract from update.app boot.img and flash.

Flash partitions on .img files is not needed.
Just find a corect oeminfo for your model phone.
Flash it on TWRP recovery.
Use dload methode to update on basical version (MarshMallow b160).
After that, unlock bootloader again and make a factory reset.
Switch on your phone (the first boot make long time).
Update on last emui on OTA.
Done!
After that you able to install a custom rom.

IT won't turn off so been always on it won't keep the charge... Writing so because apparently it won't go to download mode (dload) if plugged in. On the other way if I unplugged from power it won't even start. Shall I force to download mode using console ADB or FASTBOOT? I had looked but can't find anything...

Correct. Because I'm not able to switch it off it won't keep the charge. When discharged, the minute I do plug on charge it wakes up... That's the loop...
My main question is: does a command exist to enter download mode using terminal?

You have a hardware bug?
No abd command to enter dload mode..
Try flash a update.zip with twrp (not guaranted)
After that unlock bootloader again and make factory reset.

I'll try. Thank you

Hi, I followed this guide to go back to stock from elite rom. I flashed my oeminfo.img on twrp and then went to dload combination. Do I have to unlock the bootloader after the reboot? Thanks!

Hi,
I followed your guide and it works perfectly thanks!

How to update firmware with TWRP installed?

So I unlocked my bootloader and installed TWRP on the p20pro. Just received status that there's full update available. I downloaded and try to install, but the phone would boot into recovery and nothing happens. How should I go about updating the firmware on the device with TWRP?

Either reflash the stock recovery or keep TWRP and use HuRUpdater Tool (search for it here on XDA)

Hi.Same issue. Does reflash stock recover wipe all my datas ?
How to use HuruUpdater as ther current TWRP does not allow to access on local files (no decryption).
THanks
JP

here's the details
- Unlock bootloader from Huawei : http://emui.huawei.com/en/plugin/unlock/index
- (It's still possible to unlock the bootloader. Just send an email to your local support or tweet them (HuaweiUK). They'll ask you for some info and send you the unlock code. Took me two days to get the code)
- TWRP : https://forum.xda-developers.com/hua...2-1-0-t3779400
- hurupdater_0.3.zip https://forum.xda-developers.com/hon...overy-t3769279 also works perfectly for P20 Pro
Magisk file (if you want to get rooted) https://******************/Magisk/Magisk-v16.0.zip
Now, get patient, an old man did it!
In future direct links for our CLT-L29 european(C432)..
http://pro-teammt.ru/firmware-databa...irmware_page=0
Click on FullOTA-MF (only!) and click on filelist I had to click several times on filelist to get the links to the 3.zip files needed (thinks to Tecalote for his patience!)
So, the difficult part was to rename the.zip files( I went to #32, page 4 and renamed exactly like it was : Download firmware files (for official firmware use Huawei Firmware Finder).
1. Put files you want to flash in a seperate folder on sdcard.
Supported zip files to flash are (name must match):
o update.zip (use FullOTA file)
o update_full_hw.zip
o update_data_full_public.zip
2. Optional: Put recovery.img (rename your TWRP downloaded "recovery_ramdisk twrp_clt_0.1.img") in same folder if you want to keep custom recovery.
3. Put HuRUpdater zip in same folder. Example:
4. Select only HuRUpdater to flash in custom recovery.
5. Follow instructions on screen. Flashing can take multiple minutes.
Then I followed exactly step by step.
It didn’t work and I had error messages flashing with hurupdater_0.3.zip:
No update_data_public.zip found in /sdcard/”name of your folder”
No update_all_hw.zip in /sdcard/”name of your folder”
As you can see the name of the .zip files did’nt match #32.
I renamed exactly as asked to get rid of the error messages, and BINGO!

Update CLT-L29 8.1.0.128(C432) with TWRP already installed
Update CLT-L29 8.1.0.128(C432) with TWRP already installed
Hello,
Many thanks to all of your for your kind support , so I intend to create a summary of what I did, hoping it could help others !
I had already unlock previsouly my Bootloader (of course, else this topic would not exist) via Unlock bootloader from Huawei :https://emui.huawei.com/en/unlock_detail
I already had TWRP and Magisk installed and wanted to get the latest official firmware for my P20-PRO-CLT-L29(C432) - > CLT-L29 8.1.0.128(C432).
When intending to update (from my phone), it could not work (I allways boot back to TWRP), upgrade failed.

Start with : Do your Backup !
Removed then all security (screen unlock in developper mode =0) , no pin, no pattern, no password, no fingerprint, no faceunlock
Download the following set of files (that I've uploaded and ready to use) : https://mega.nz/#F!pEpRDB7R!pmPDjlqgtdHTs39gyLdJhg
(nota : my upload is quite slow, so please wait some hours before it is available)
It contains : HuRUpdater_0.3.zip, Magisk-v16.4-Beta.zip, twrp_clt_0.1.img, recovery.img
, update.zip, update_all_hw.zip, update_data_public.zip
- On your phone create a folder including all files from the package above.
- Boot in TWRP
- Install : HuRUpdater zip from the folder where you had put all files (no issue with decryption, at least in my case)
Nota : I had almost an heart attack during installation as it did a reference to CLT-09... not CLT-29 but it works and this despite some strange error messages.
When achieved : wipe/cache dalvik.
Phone will reboot and optimize the apps.
In my case, I lost my root access and TWRP, so I've done it again, but normally it was supposed to stay when using HurUpdater
Install TWRP (again if needed) :
- Start your device in fastboot mode
- Install the recovery using the following command : fastboot flash recovery_ramdisk twrp_clt_0.1.img
Restart with this command: fastboot reboot
Important : As soon as you execute the restart command,remove the USB cable and keep pressing Volume UP, so the device will boot to TWRP. This is to avoid that the device boot to OS,overwritting TWRP recovery.
Reboot again in recovery
(re)Install : Magisk-v16.4-Beta.zip
Have fun,
JPh

You lost twrp because you didn't rename the file as recovery.img

THANK YOU! THIS WORKED SO PERFECTLY!
Until now, I tried the following:
Back up my data and apps to SD card with EMUI Backup App
Download OTA update (it first downloads the incremental ~100-200MB update) and click install
This doesn't work of course - TWRP tries to execute the update command but dies with error messages
Reboot, try downloading/installing updates again, the downloader then downloads the -FULL update
Extract recovery.img from update.zip>update.app
Flash stock recovery over TWRP
Initiate update again from Update App (System Settings)
Update runs smoothly, but bootloader is locked again afterwards
Restore from backup, flash TWRP again, flash SuperSU again
BUT THIS IS MARVELOUS! I will only lose SuperSU and Xposed, and given that HuRUpdater is provided with the correct filenames including TWRP renamed to recovery.img, I will just have to install SuperSU and Xposed again after updating the firmware.
It worked flawlessly with the stock firmware files from update.hicloud.com, and you'll usually find all the links a few hours after the release somewhere on the internet.

I have a few questions regarding this method to update :
Do I need to make a new backup using twrp after this update since the system files changed due to the update? (correct if i'm wrong i'm a previous iphone owner this my first android device)
Is the any method to force update 8.0 even it will erase every thing and after that just flash twrp and restore backup (i think all the methods mentioned are complicated for me)

Hi, I have the same problem but with my Huawei P10Lite WAS L1XA with firmware oreo installed from the phone and on reboot enters twrp mode.
Can I ask you to look for the files for my model?
(I spent three hours looking for those files but I could not find anything) ...
