Some context:
My MHA-L29C432B138 with TWRP got an OTA update on the phone itself, and I wanted to update (it wanted me to update to B182).
Since I had TWRP replacing the stock recovery I could not flash it through the normal way, so I went ahead to replace TWRP with the stock recovery so I could update.
I was unable to flash the stock recovery since I had no access to flashing in fastboot (FRP Lock, PHONE Unlocked, OEM unlocking option greyed out in developer settings), so I attempted to relock so I could unlock again, hoping that would solve my issue (fastboot oem relock KEY).
By doing this my phone went into a reset, now I'm stuck at FRP Lock, PHONE Relocked, and I can only access the bootloader and eRecovery.
eRecovery is attempting to download updates but fails every time, and I can't use HiSuite to do a system recovery neither (says my device is not supported).
So this is where I'm stuck, any help would be nice!

Try to unlock after this.
This does low-level format.
My device: Mate 9 supersu B190 Mediapad X2 GEM 701->703 B212 KangVIP (AJ mod)
Everything in fastboot (flashing, locking, unlocking) was unavailable, eRecovery was not working, HiSuite said my device was not supported, and dload didn't work neither (tried 3 different firmware versions).
After spending 1-2 hours on Telegram with others I ended up using funkyhuawei with eRecovery, only thing that worked for me.
Last time I buy a Huawei device for sure, their own services don't even work (eRecovery, HiSuite).

As I said here, for your case the patched HiSuite method would have worked. But it's too late now, you paid, I was in holidays.. I know it's a shame that HiSuite says unsupported or erecovery not working but you could have made your phone compatible by writing some text in a file and using Lucx's script instead of paying funkyhuawei, their service never worked for me.

I had the same then suddenly it is hardbricked no charging no nothing . It was a 1 month old phone. I didnt do anything other than downloading a c636 oreo and i was c185. But i received it trough the system update using firmware finder and even it authenticated itself. Even installed it with no problem. Then suddenly it broke and after soft brick became hard brick nothing. Now it in service centre i hope they can fix it. It is under warranty. pray for me

Same problem here with Mate 10, can you teach me how to write some text in a file and using lucx's script instead of funkyhuawei? THANKS!
I had my phone on the last beta version of Oreo, but I was not getting the official OTA update to Oreo. After reviewing many posts I came to the conclusion that would have to sideload the Full OTA version via Google website. I also want to mention that while I was on beta the OEM Unlock option was grey out, because of this I could not perform a full factory reimage.
Once I completed the sideload to the latest version 8.1.0 (OPM1.171019.016, Feb 2018), I now was showing unknow baseband / no IEMI numbers. When I when to see in developer mode I now can toggle the OEM Unlock option and ran fast boot to reflash factory images. But I still have no baseband/IEMI.
I believe I might have found a way to unlock the bootloader accident, but at the same time cause an issue with my baseband/IEMI.
If anyone can share any thoughts on how to fix my issue and potential replicate my success in unlocking the bootloader.
Have you tried flashing twrp and from that flashing a modem? Is there even any modem zips available for the pixel? If its possible this might allow us to unlock the bootloader, im glad to experiment, i have a spare verizon pixel but it seems that unbrick recovery methods arent widely available for the pixel at a quick glance.
I haven't tried flashing twrp yet. I have tried using fastboot to erase modem 1 and 2 and then reinstalling factory img ( which if I am not mistake has the modem and radio img) but no luck still showing Unknown baseband and IMEI. I am think about installing an older version of Oreo to see if I have any success, but not sure if this will hard brick my device.
I wonder if since my phone hardware version is from Version would their be a specific modem for it versus what available on google site? Maybe this is my issue. Or flashing a custom ROM then flashing back to stock would this fix my issue as well.
Short question: how can I downgrade or FRP unlock a S8+ G955F that is FRP locked and on very recent firmware?
Here are the details:
I am trying to assist a family member with a Galaxy S8+ (SM-G955F) that they have just purchased online. When purchasing it they were not told that FRP lock is on (FRP LOCK: ON) and OEM lock is on (OEM LOCK: ON). It was running Bootloader v2 on very recent stock firmware. It has been successfully flashed with BL_G955FXXU2CRED and AP_G955FXXU2CRED...
It was on G955FXXU2CRED firmware. I was able to successfully able to flash the Combination ROM COMBINATION_FA70_G955FXXU2ARE1 (full name COMBINATION_FA70_G955FXXU2ARE1_CL12792727_QB18097821_REV00_user_mid_noship.tar)
With combination rom, it seemed that I could enable USB Debugging, and also follow the steps for *#0808# IME to enable the appropriate mode for adb codes to be entered. I was able to find the device with 'adb devices', and I thought that the FRP unlock codes on the command line worked. But after re-flashing to the current Stock Firmware again, FRP lock was still there.
It seems I need to downgrade to Nougat 7.0, but I am on Bootloader V2. Odin identifies it by a FAIL with binary not matched (2 vs 1). So it seems that if I could get a method to keep Bootloader V2 and install Stock Firmware for Android 7.0 Nougat, I would be halfway there to fixing the FRP problem. However, I can't find any firmware or ROMs for G955F that includes Bootloader V2. This is identified by a U2 in the firmware name, like: G955FXXU2CRED . Is there a way to keep the BL Bootloader V2 but install AP ROM from Nougat?
I have spent many hours on this so far, and I just wanted to say thank you to all you guys who are helping on XDA, I really appreciate it. I have read about 7 day waiting periods for OEM UNLOCK but I don't see how it applies, as I can't do anything aside from use Combination ROM, use Odin, or go to the FRP locked FW which seems to be a dead end?
If there was a reliable method for rooting this G955F device with this G955FXXU2CRED firmware, I would be open to trying it.

Another note: AP SW Rev is identified as B:2 K:1 S:1
I don't think once a phone has the boot loader CRED, that the phone can be downgraded. Hope I am wrong.

I think you are right. The combination ROM seems to built on selinux version 7.
I think I need to root with twrp. But first I need to enable OEM unlock. I'm not sure if that will be possible with combination ROM or if I should flash latest stock and then wait 7 days??
same problem here... If an solution available pls write here

Flashing stock rom and waiting 7 days would be the safe option.
I am not exactly sure what you are trying to achieve.

I think I read someone on CarHDRom who flashed the rom via TWRP, and then when the phone booted into system for the first time at setting up, they changed the date to 8 days earlier, and when the phone setup was completed and booted into system, the OEM unlock was available.
Re: CRED I believe once it has been installed on a phone, you can not go back to a previous version (pre CRED).

Download latest odin and try again. I too got stuck in similar situation. Realised the issue is due to Odin. If you are using latest and encountered this error, try one version earlier.
I too can confirm that the combination-ROM works like a charm with odin. FRP kinda unlocked itself
Hello
I've been reading forums and downloading files for days. Many of the links in the posts no longer work. Posts are 5 years and older. There are no new ones. At least not one that actually works. Downgrade I mean. That's why I wrote this question and I'm asking for help - how to really downgrade my Galaxy S6 G920F.
Thanks for the help.
PSA: Downgrading WILL void your warranty!
What have you already done (what method, software) have you already tried?
The 100% surefire way to downgrade your phone (or any android phone really), is to:
1. Backup your phone data.
2. Switch the phone into download mode, connect to PC, boot into TWRP recovery through fastboot
3. Wipe your 7.0 firmware and all data
4. Flash android 5.02 ROM
For a samsung phones ODIN + Freya is also an option. Odin is a samsung's firmware flashing tool, Freya is a 3rd party program that can download the stock firmware android for you. All of these tools are available online, and you can ask on a samsung subsection of XDA about how to use them - people can give you up to date links.
I'm laughing because you write quite a lot in three days. Of course, this method does not work.
Is there anyone willing to help?

That is assuming they have TWRP.
Also, the part you mention about "boot into download mode, connect to PC then boot to TWRP via fastboot" is not correct because Samsung is not compatible with fastboot, adb works but fastboot does not. Some Samsung devices technically have a "fastboot mode" but it isn't functional, it doesn't respond to fastboot commands, it's basically useless.
Also, you can't flash a firmware that has a lower binary than the currently installed firmware so if the binary of the downgraded firmware is lower than the binary of the currently installed firmware, the downgraded firmware can't be flashed.
Samsung is making it harder and harder to downgrade their devices.
OK. I'm afraid I'm missing the point of what's being said.
I know it is possible and there are also posts about it, but they are old, the links in them do not work. I'm asking for an expert who knows how to do this, philosophizing about what it would be like if it somehow doesn't really help me and I'm not interested either
I'm only interested in a positive thought, help and not brainstorming, if you understand me?
No offense
I accidentally purchased credits for dc-unlocker/HCU instead of the three day option (which I have since purchased and used to unlock my bootloader using a hardware TP) so if these are of any use to someone else let me know.
Hello. Can i use that to unlock my P20 Pro?

Unfortunately they're no longer available, but you can use the same software to unlock the P20 Pro like I did. It's a little bit of a process, but I've got notes from when I did it if you are interested and I think I spent about 20 EUR for the 3 day licence of dc-unlocker/HCU. In the end I did it with the hardware test point because my back cover was loose and I intended to replace the battery anyway (it was bulging)

Can you tell me the process please. I was thinking of buying the 3 day license or MOS but i don't know if I can do it or not (don't have any expertise on anything hardware related)

I unlocked my P20 Pro using a hardware testpoint, the HCU software, and a lot of time. I would suggest reading the information below, gathering all the tools/software/ROMS/IMGS you need and asking any questions before you purchase a licence or attempt this process.
WARNING!!!! THIS WILL ERASE YOUR PHONE COMPLETELY!!!
I would suggest making sure if you are going to purchase the 3 day license (this is what I did) that you are available to work on the phone for a couple of days (maybe buy it just before the weekend?) as if you run into any issues you won't have much time to fix them.
WARNING!!!! THIS WILL ERASE YOUR PHONE COMPLETELY!!!
BE CAREFUL TO PURCHASE THE THREE DAY LICENSE AT THE CHECKOUT NOT THE CREDITS (I MADE THIS MISTAKE AS YOU CAN PROBABLY TELL FROM THIS THRED)
Otherwise, the steps I went through are below, as well as some of the links to things I found helpful during the process:
1. SOFTWARE VERSION - It was not possible to unlock the bootloader on version 10 of the OS, so you will require HiSuite (https://consumer.huawei.com/au/support/hisuite/) to downgrade or dc-phoenix to flash an earlier version. I used 9.0.0.168 for my phone (Model: CLT-L29) so will reference that in all the steps below, but use the corresponding version for your phone (whichever you downgrade to from HiSuite should be fine?)
2. TESTPOINT - I used the hardware test point (next to the camera once the back cover is removed) but apparently this is possible using the software test point process (I am uncertain of the exact process for this, but there is a guide on the dc-unlocker site somewhere)
3. ADP/FASTBOOT RECOVERY UNLOCKING - Once the HCU software has provided a new code (or if you already have one) you can use fastboot oem unlock <code> where the <code> is the bootloader unlock code to unlock.
WARNING!!!! THIS WILL ERASE YOUR PHONE COMPLETELY!!!
4. ALTERNATIVE OS INSTALLATION - In my case I installed LineageOS 16 using an old guide (https://web.archive.org/web/20210726230701/https://depl0y.com/posts/P20-Pro-LineageOS-Guide/) which will only work (even the official version) if you patch the Lineage installation (update-script requires editing or replacement)
Install TWRP
Enable USB debugging
adb reboot bootloader
fastboot flash recovery_ramdisk twrp-3.7.0_9-0-charlotte.img
Hold VOL-UP & VOL-DOWN
fastboot reboot
You should now be in TWRP.
Flash LineageOS (and gapps)
In TWRP go to Advanced > ADB Sideload
adb sideload adb sideload lineage-16.0-20210211-nightly-charlotte-signed-modified.zip
adb sideload open_gapps-arm64-9.0-nano-20220215.zip
In TWRP go to Reboot > Bootloader
fastboot flash recovery_ramdisk RECOVERY_RAMDISK_9.0.0.168.img
fastboot reboot recovery
You should now be in the stock recovery. If not, boot into stock recovery
Select Wipe data / factory reset
Reboot system now
THE P20 WILL ONLY BOOT WITH THE STOCK RECOVERY, SO REPLACE IT AFTER USING TWRP
5. WEBVIEW FIX FOR GOOGLE APPS - DO NOT SET UP WIFI DURING INSTALL!
Download com.google.android.webview.apk from apkmirror and copy to the device. Install using the default file manager and reboot the phone. Sign in to Google and update webview, google apps, etc
6. ROOT ACCESS - MAGISK
Install apk (copy to storage and run from files) for Magisk and patch RECOVERY_RAMDISK_9.0.0.168.img.
Reboot into bootloader and flash to recovery: fastboot flash recovery_ramdisk RECOVERY_RAMDISK_9.0.0.168_magisk_patched-25200_8akQl.img
TO BOOT PHONE WITH ROOT BOTH VOLUME UP AND POWER BUTTONS NEED TO BE HELD AT STARTUP!
