Bootloop after update from b331 to b513

Hi guys i have a serious problem as many of u right now with updating to MM our Mates.
I tried to flash B513 update on B331 firmware, but i extracted zip file (i think it was that mistake). After that phone went on bootloop and i cant access to ROM. I also copied zip file and tried 3buttons method to flash it again, but its stuck at 5%. I have LOCKED bootloader, CAN access to stock recovery, fastboot&secure mode, but i CANT do anything with adb on my PC. Is there any slotion to fix that? I also tried to generate code of bootloader, but i cant access Product ID of my phone. Is there any help right now?
Sorry for my poor english, but right now i'm bit nervous of this situation
EDIT: I unlocked bootloader, now what im supposed to do?
EDIT2: Installed TWRP for MM, can i just now install B522 full rom or i have to do it in different way?

FRD-L19C432B120 Stock Recovery

Hello!
I own a FRD-L19C432 device loaded with B120 FW, TWRP flashed to erecovery, the recovery partition is stock (?) since I haven't flashed anything on it and it is also rooted.
A few days ago, I got the notification of the availability of B131 update. According to some info I've read over the web, the erecovery isn't/wasn't used for anything, so I tried my luck and proceeded with updating operation from UI. It booted to recovery, failed to install, showed some error and booted to OS, that stills on B120.
Introduction made, the question is:
I already downloaded the FRD-L19C432B131 full update zip, can I simply flash it through the dload method, or, must I first unroot and flash stock B120 recovery in order to perform the dload flash?
If so, where can I get the B120 stock recovery and erecovery? I'm not finding it while using the Firmware Finder app by Team MT.
Hope you can give some help.
Tks,
RM

you can extract the recovery.img using huawei update extractor and then flash via adb or the multitool

Stock recovery from B120, right? If so, where can I find this recovery since I'm not finding the full B120 FW zip?

Try huawei firmware Updater by team mt (can't remember full name) to search for the last update and extract using tool from post 1 ^^

It's weird and sad to hear that you flashed twrp to erecovery.
Let me explain u briefly what erecovery does . when u use dload method (while flashing an update.app) , erecovery extracts all .img and .bin files and later it flashes the each file (image files) to its respective partition .
In ur case. The normal stock recovery flashed the update.zip which was included in the script . but it failed to extract update.app in the update.zip and finally output u got is error.
Solution:
The only solution for this problem is ..
Download a full update package of stock ROM...
Extract Update.app (use huawei update extractor) and then find erecovery.IMG
Install adb and fastboot drivers ..
Put your phone in fastboot mode .
Connect to PC ..
In the terminal (command prompt) , type this command and hit enter .
fastboot flash erecovery erecovery.img
(From here u can reinstall the update.zip ) if it fails .
And then try to shutdown the phone , later put full update.app in dload folder ..
Use the 3 button combination to install full package of update.app and thats it .
It reboots to stock again .besure to take a backup of your data before attempting above step . after everything done check for update from settings and install it normally

hello!
Thanks for a proper answer
At the moment I'm stuck (paused) at the TWRP backup operation, since I don't seem to be able to perform a full back to internal storage (with the previous NEXUS phones I owned it was possible...) I need first to get an USB-C adapter in order to use USB OTG to perform the safety backup.
After That I'll flash B120 stock recovery and erecovery, unroot and dload the new FW version.
Meanwhile, another question: Using the FW Finder APP from Team MT on Windows it gets a FRD-L19C432B131 result, while on the Android version of the same AP it only finds B130, not B131 (?). On the other hand, I can only find the B120 full FW over Android APP, and don't seem to find it while using Windows... Any idea why this occurs?
RM

Hello!
Task accomplished! TWRP full backup made, flashed stock recoveries from B120 and after that flashed B131 update.app though dload method.
Everything went OK except for the fact I got bootloader relocked after the second flash. I miss the simplicity of the Nexus devices...
With the TWRP backup made before I was able to restore most of the definitions though. It would be nice to digg a workaround to flash update.app without getting bootloader relocked...
I wonder if extracting boot, system and recoveries IMGs and flash all this through fastboot wouldn't work!? Did anyone tried?

Reverting to stock [SOLVED]

I have been trying to revert to stock with no luck. What I want to do is install the latest update, but I can't because I had twrp installed. I flashed the original recovery. The problem is when I try to use eRecovery I get "Getting package info failed" error. when I try to download the b385 full update for the FRD-L04 I get a dead link. I was able to download the rollback package, but will I be able to get back to the latest version after I install the rollback package? when I try to use other update packages for my phone I get "Incompatibility with current version" error. Do I need to lock my bootloader in order to update? The good news is that my phone works fine, bad news is that I can't up date.
build number: FRD-L04C567B385

Thanks for the link, I just been to heck and back with this phone. first I uninstalled Magisk. After that my phone wouldn't boot, it would just hang on the blue screen after the initial boot screen. I tried to find a stock boot Image for my version. Once I installed that my phone would boot loop so I managed to get into fastboot and flash TWRP. Once in TWRP I restored my B360 backup and got my phone working again. Then I flashed the stock recovery. Tried to boot into the stock recovery but that wouldn't load. Some how I got it to install the rollback package and now i'm at version B300. Good news is I'm back to stock and can boot int the stock recovery. Time to see if I can update to the latest version.
Edit I think I might have a problem. It won't let me update also it shows my phone as "FRD-L04C900" not "FRD-L04C567" is there any way I can fix this?

I think you will have to restore you oeminfo partition backup through twrp.

On mr FRD-L09, I had to relock my bootloader, then get the rollback package and put the .app on my SD card and hard flash it, then do the same with the rom .app file. Thet got me back to stock marshamllow, and I just let all the updates run through until I'm now on the latest.
Stock is missing some bits, and has some irritations, but the camera is sooo much better than custom roms, and GPS works, as does Android Pay etc. I've not bothered rooting, AdGuard does the ad-blocking and the rest is liveable.

Well I think I'm my phone is screwed. I can't boot into recovery and when it boots it bootloops once and then it is stuck on the "your device is unlocked and can't be trusted. Fastboot still works fine I can lock and unlock the bootloader. I can flash Recovery and TWRP in Fastboot but neither one will boot. I think I might have flashed the wrong update or it happened when I flashed the rollback package. I want to try DC Phoenix but they won't let me buy credits because my PayPal account is unverified. I have downloaded the "Honor 8_Firmware_FRD-L04_Android 6.0_EMUI 4.1_C567B122_United States_Nonspecific" from the hihonor.com site. I extracted it and flashed the recovery, boot, and system image through fastboot. The phone still won't boot into recovery or boot into the OS. Is there a way to fix this or is it time for a new phone.
Thank you everybody for your help.

Ok my phone is fixed. What I did was buy 15 credits for DC Phoenix and flashed the "Honor 8_Firmware_FRD-L04_Android 6.0_EMUI 4.1_C567B122_United States_Nonspecific" package. When I rebooted my phone it automatically went into ERecovery and downloaded and installed the B162 update. I was able to fully boot after that It updated to B360 and then B388.
Thank you everybody for your help.

How did you flash the file you mentioned above? Did you put it on the SD card and used TWRP?
Also, what is so special about that file?
I have the L14 (64gb US version) and just about the same exact problem you describe.
If you have any extra steps that would help me recover mine that would be great.

I followed the instuctions for the honor 7. I would recommend finding the full update firmware for your phone. It took me a lot of googling to find it. Make sure it is the correct firmware, you need to match the numbers before the B-- for me it was (FRD-L04C567) and for you it would be (FRD-L14????) I hope this helps.

After you flash the firmware, you must format data with emui recovery, and it will boot up

After trying different methods, this one works
Download
1 .Honor 8_FRD-L04_Rollback_Package_from_Android7.0 to Android 6.0_C900B300
2. Honor_8_Firmware_FRD-L04_Android_6.0_EMUI-4.1_C567B122_United_States_Nonspecific
Put on dload (sd card) #1 after shutdown the phone and put on the folder dload (Sd card) #2. after reboot your phone starts with android 6.0

Try this

Ok so i had the exact problem, im not sure if this will help but what I did was flash my cust recovery system and boot through bootloader, I then put the dload folder on my sdcard with the update.app in it, from there I put my phone into download mode so hold all 3 buttons until it goes into download mode. Once there it will automatically install the update.app, and you should be good to go. If not than go to recovery mode do a factory reset and wipe the cache and see if that works.

How to flash via TWRP a stock ROM in my problematic phone

Hi everyone.
I am facing a LOT of troubles with my phone (as stated in this thread).
Anyway now I have again unlocked bootloader, installed TWRP 3.1.1, rooted but I have a strange ROM installed by a service tech shop after the phone became unusable.
The problem is that this ROM does not show an update option in settings so I am stuck at 1st march security patches.
Here attached my actual Build Prop file.
The ROM seems to be a BLN-L21C900B300 (never heard of this and not even found on Firmware Finder) and the fingerprints show a "test keys" rom:
device: HWBLN-H
Display: BLN-L21C900B300
Fingerprint: Huawei/generic_a15/generic_a15:7.0/NRD90M/jslave04010520/:user/test keys​
If I try to flash via TWRP a BLN-L21C432B360 (which was my previous stock ROM) it does not work and on TWRP appears the following:
......
write radio image
check_write_data_to_partition
write data error
E; unknown command (errno)
update_huawei_pkg_from_ota_zip: update package from zip failed
updater process ended with ERROR: 7
error installing zip file '/external_sd/update_full_BLN-L21_hw_eu_zip'​
I cannot flash the FULL zip file with the core of the ROM but I can luckily flash the data, so I could get back Radio Fm and possibility to install themes....
To make the story short: is there someone who knows what this error is? Maybe I can get a solution.
Moreover: maybe this strange "device: HWBLN-H Display: BLN-L21C900B300 Fingerprint: Huawei/generic_a15/generic_a15:7.0/NRD90M/jslave04010520/:user/test keys" is preventing me to flash?
Changing build prop file can be useful?
Thanks to all.

I forgot to mention: dload not working. Always error.
That's why I think TWRP is the only solution

B300 (at least for the BLN-L24) is the first of two update packages to rollback from Nougat to MM. The first update will take you from the latest firmware to B300 and then the second update will complete the rollback to your device's stock firmware.
dload this package to complete the rollback then do a factory reset and wipe cache partition in stock recovery. After that download and update to the latest firmware and proceed to unlock BL and flash twrp and you should be good to go.

And before doing it I have to flash the stock recovery?
My phone was, we can say, flashed in some way by the tech shop to this strange version of Nougat and with the "test keys" fingertips.
With the files you provide I should "dload"?
I do not understand your post.
please explain better.

Download the zip I linked above from Huawei website. Extract the update.app and put it in dload folder on your external SD card and force flash (power vol - vol +). It will flash all the stock images and return your phone to factory firmware android 6.0 EMUI 4.1. It might bootloop after this but booting into stock recovery (power vol +) and perform factory reset followed by wipe cache partition will get you booting. Then you can OTA update to latest firmware and root again.

Well, I will try this weekend. Now the risk to stay without phone during working days is too high
Ah, BTW, thanks for suggestion.

Since you have nothing to lose right now just try the whole rollback process. Here is the update that the service center used to get your phone to BLN-L21C900B300. You can try flashing that again through dload or skip to trying to flash this. There are two different firmwares listed as the 2nd part of the rollback and you already said the last one I gave you failed so give this one a shot. Let me know how it works out for you:good:

Have you tried the Team MT huawei multitool to flash the images from the firmware? Use the Huawei update extractor tool to get the boot,cust,recovery,system and userdata.img from the firmware you tried to flash and then put them in the unbrick folder in the multi tool. Put phone in fastboot and run the Multi tool and use the unbrick option. I know your phone is not bricked but this way it will flash all 5 images in order through fastboot. You could actually try and flash the most current firmware with this method and avoid having to system update from MM to Nougat.

yes, exactly, I am trying with multitool . another bro suggested me how to do it even if with a slightly different method.
"You need flash the oeminfo via multi tool and then same firmware file for your current version via dload. It should be fixed".
WTF....never sweat so much for a phone. And never had those problems flashing samsung... and I was flashaholic

Yes, I have learned so much about this phone and the flashing/brick/unbrick process in the last 2 weeks.

When I go to multitool "unbrick", it asks for custom.img, but in no update.app of my firmware is present.
Moreover now I just can enter erecovery. It does not boot. I can enter fastboot only. Multitool is now not recognizing the phone. Do you know how to proceed?
I put in dload the firmware .app, but it says "software install failed"

Pheew...I managed to have again that fuc..ng C900B300.
I entered fastboot and repeated the unlock bootloader process. That way the phone got a hard reset and started over. Believe me when I say I tried all the methods I knew.
I think there is something locked somewhere in my partitions (I am not an expert of course) that prevent me to do deep modifications. Now I just can TWRP data but not the core. And again I have no update option. I think I am stuck forever at this stage with 1st march patches and nougat 7.0.
I do not think I will be ever able to have Oreo.
Amen. I am really tired to waste my time with this s**t. Next phone will be again a Samsung or One+. Full stop. Stop chinese brands.

Where are you located, Europe?

Yes

Ok bro I really hope this is it. Full firmware BLN-L21C432B151. I already downloaded it myself and checked with extractor tool it has all the images you need. Since you have fastboot back use the multi tool unbrick again and now that you have all the necessary images cross your fingers it will work.
And I agree with you about the phone. Made up my mind im giving this turd to my sister and getting the OP5T in a few weeks.

Thanks. I will do it this weekend. Today I spent 5 hours to get back my configuration after the hard reset with the apps I use for work. Cannot risk again tomorrow.
In another thread, sashank suggested to change OEM file because probably phone doesn't recognize the firmware I want to install.
It didn't work and lead me to start from scratch with the same strange build.
I will try your method but first I must study better the procedure because I don't want to mess up everything and risking to throw the phone in the garbage (where it belongs in the end...).
Thanks.

Honor 8 (FRD-L09) brick help.

Hello.
I need a help with my Honor 8, it's been bricked and I honestly don't know if there is much to do in my current situation.
So the phone has locked bootloader and stock recovery.
Fastboot always returns 'Command not allowed'
What exactly happened:
I was running Stock ROM, rooted, TWRP Recovery with unlocked bootloader.
An official OTA update popped-up on my phone, I was in a rush and I missclicked (don't even ask lol) and the update started installing, I knew I'm screwed.
So I was about to play with fastboot, but it always returned 'Command not allowed'.
And probably the worst mistake happened a few minutes ago (6:00 am trying to fix it half a sleep), I was reading some posts about the dload method, >>FASTFORWARD I installed an official update using the dload method and locked my bootloader by doing this.
QUICK SUMMARY:
So I'm stuck on a bootloop.
The 3 button combo works.
Stock Recovery works as well.
Fastboot does NOT work. (I tried flashing, unlocking, temp-booting.. but nothing)
adb always returns error:
Code:
device unauthorized.
This adb server's $ADB_VENDOR_KEYS is not set
Try 'adb kill-server' if that seems wrong.
Otherwise check for a confirmation dialog on your device.
Is there ANYTHING I can do in my current situation? :crying:
Thanks in advance for any help.
Have a nice day.

Hello, as long as you have an official recovery, a proper BOOT.IMG and the dload method is working there is still a chance( i hope), the only thing you need to know is that if the firmware is the wrong for your phone it will deny it. It means that is if you try to install an android 6.0 based stock ROM over a 7.0 ROM , it will say software upgrade failed or something like that.
You need to know under which Android version you were and install the same or maybe a more recent one but not to far away from your actual ROM, try the next one. You can also try to downgrade USING a rollback package that you can download on honor official site. Make sure that's the the correct file for your phone.
Hope you'll make it bro, let me know how the situation evolve

Try to flash the rollback package and then an EMUI 4.x ROM. They're both available on honor official site

Hi Ryan,
Thank you so much for responding.
I could see two ROM in the official site http://www.hihonor.com/in/support/
HONOR 8 Firmware (FRD-L02, C675B130CUSTC675D002, India)
HONOR 8 Firmware (FRD-L02, Android 6.0, EMUI 4.1, C675B160, India Channel)
I tried with both the ROMs but no luck
I placed the update.APP file inside sdcard but the update stops at 5% showing that it has failed.
I also tried flashing the recovery.IMG in fastboot mode.
I have lost all the hopes in my new phone
In the rescue mode it says UNLOCKED.
Please guide me with some detailed steps.
Thanks

Flash the stock recovery of the ROM that was previously installed on your phone , then with dload method flash the rollback package downloaded from honor site , and finally flash one of the two ROM, it may resolve your issue because the phone won't accept a lower firmware without flashing the rollback package first. As long as you can use dload method it should be fine.
If it doesn't work try to flash boot.img , recovery.img, cust.img, vendor.img and system.img extracted from a clean firmware downloaded on honor official site
Let us know how the situation evolve
