Hello, i tried to downgrade my P20 Lite (ANE-LX3 C69), i tried the dload method but always said, incompatible, and errors, i found in internet that maybe was an MicroSD issue, so i went for another method, HiSuite, i selected the firmware, everything looked good, so, i started the update(Downgrade), started downloading, installed, after that, my phone rebooted, and started installing, after that, my phone rebooted, but nothing in the screen, and now is in that state, black screen, My phone is in fastboot mode
I saw in other threads to flash a rom, but always says like, change something in the partitions, or using TWRP, but i have my bootloader locked
Is any way i can do something to fix it?
If more info is required, i can edit the post with it, just tell my what is necessary
Try this
Code:
fastboot devices
fastboot reboot
to exit phone's fastboot mode
I tried that
fastboot devices shows my phone
s/n fastboot
and with fastboot reboot, it just reboots and gets back to fastboot, nothing in the screen of my phone, just vibrates

Purchased an Lg Gpad 7 Wifi tablet (v400) 2 weeks ago. Came with preinstalled Lollipop android so i couldnt install a recovery rom to flash any other custom roms. Downgraded to Kitkat version following the instructions on Xda forums and succesfully installed Twrp. When i installed Cyanogenmod 12.1 through Twrp i got stuck in fastboot screen.
Any suggestions and / or solutions would be greatly appreciated.
I had a similar problem.. Only mine was stuck at the bootloader. Go in TWRP and repair /data and other partitions. My data partition gave me an error since F2FS is a little flaky and some ROMs corrupted it (claimed they supported it). I would recommend erasing the system, cache and data partition if you can't get into TWRP.
The problem is i cant get out of fastboot whatever i try. It says start on bootloader but the tablet just restarts on an empty screen doing nothing.

if you have an sd card, try removing that, then reboot.
if that doesnt work, try entering fastboot command, fastboot continue
Tried without sdcard and i get the same fastboot screen.
How can i give any commands? The only options i have are Restart Bootloader / Restart / Power off. Tried restarting bootloader but i get nothing in return tablet just stays on with nothing on screen.

you said it was stuck on fastboot, if thats the case, install any needed drivers on your pc, connect device to it, open a terminal in the fastboot dir (after you go get fastboot), then try those commands i gave. you could also try, fastboot reboot dont think i mentioned that before.

Did as you said but every command i gave gives me an error message in adb terminal. There are new lines in fastboot menu in tablet now. Bottom two are SECURE BOOT - enabled & LOCK STATE - locked.

hmm, ok, im guessing it would have said that normally, when not broken. all the command does is try to release it past where its stuck. it doesnt actually flash, lock, unlock, or change anything.
imo, this seems good, because now we know fastboot is working.
i own lg devices, but not your specific device. i would hate to give you some bad advice and make your tablet broken more, but if it were me in this situation, i would try to flash the factory KK firmware you used to downgrade with odin or however you did it. hopefully, that will clean everything up and let it boot properly.
if for whatever reason you cant do that, we could try extracting the factory file, and just flashing recovery and system, those should be the only things that got changed putting on twrp and cm normally.
Sorry, I have the serious proplem wtih my LG pad V400, I rooted it and using <LG Flash Tool 2014> with <V40010c_00.kdz> to downgrate the firmware but their is error then my LG pad stuck in fastboot menu as with just turn off, restart and restart bootloader. if i seclect one one them the tablet just logged again the fastboot menu
it stuck on the fastboot menu and i cannot do nay think with it. I can restart with factory restore mode but when select yes to restore, it will restart and log in fastboot menu again.
I downloaded adb and fastboot program and put in one folder <Minimal ADB and Fastboot> in C:\Program Files (x86)\Minimal ADB and Fastboot
I dont have recovery image so i download file <cm-13.0-20160421-NIGHTLY-v400-recovery.img> form your link to download TWRP file
move it to folder of fastboot programe and changed its name to <recovery.img>
I turn on the tablet and it waited at fastboot menu
when i run the command <fasboot flash recovery recovery.img> and they said some thing wrong like in picture
please help me
So I had an unlocked H8 with LOS. As I wanted to install EMUI, I put the proper restore Update.app into the dload folder and started Huawei's recovery. Everything went well, I formated data and wanted to install the EMUI 4.1 ROM using the same method.
Unfortunately my H8 is bootlooping and there is now way into erecovery nor any other recovery. It simply reboots on every single known vol up or down key pressing combination. The only thing I can go to is fastboot mode when holding down vol down and plugging in usb wire. But, it says frd locked and I can't install nor boot twrp. It's simply gone and reboots all the time.
Any hints? I can't even turn it off.
I wanted to give away that phone that's the reason. Last time I did it this way, I could flash the EMUI 4.1 since it's signed. But not this time.
Interesting part is, that although fastboot says frd locked, I still get the "phone unlocked" warning on every reboot. dload method isn't working, as it simply keeps rebooting.
It's my hardest brick so far I ever encountered
the same thing happened to me.....on my phone lock/unlocked frp and bootloader were tweaked for some reason(I mean that what was written wasn't the reality) so how did I fix it? I kept on to flash rollback package many times and I tried to unlock/relock bootloader again, at the end the phone let me to flash the firmware, I didn't know how but the phone allowed me to flash things throw recovery(using dload method). At the begin I only could access to erecovery and fastboot. I suppose that I broke system and data partition and while I looked/unlocked the bootloader, the wipe fixed the partition table. Sorry I'm tired and I know that my English sucks, I hope you understand what I have written.
How did you enter erecovery as this isn't working for me.... What did you flash over fastboot?
Have you tried flashing the firmware separately using adb on computer?
For this you just need to extract the Update.app using the firmware extractor for huawei. Then flash them individually using adb commands in cmd.
I can't access any state that would allow to do adb.

sorry. I'll try to explain better, however on Huawei/honor devices there are not one but two recoveries, so one is the normal recovery flashed in recovery partition, the second one is the Huawei recovery that is flashed in recovery2 partition, so if you didn't touch recovery2 partition, your erecovery is still there, now, if you press VOL+ VOL- and POWER it will reboot to recovery2 and it starts to flash something from dload in your sd card, so in my opinion you should do this things, first try this method to flash rollback package(this is the transition package from 7 to 6 and you will find it on honor site) if this is still not working try locking and unlocking again your bootloader(I hope this fix partitions of your device) then try to enter recovery and do a wipe and then boot your device, if this doesn't work flash rollback package(now it would work) and then flash an emui 4 full firmware image, always using dload method. trust me... I did the same... and it worked for me. let me know if it works for you :good:

I ran into this issue not that long ago. What you have to do is relock your bootloader using ADB. The ADB commands and instructions can be found in this thread.
Just a FYI, do not use the links to the software listed in that thread as it is a little outdated. The method still works but the software will probably not work. Just be sure to get the most recent/appropriate version of SuperSU and TWRP via their official threads (This is if you want to re-root). There are Honor 8 specific TWRP files if I remember correctly, so be sure to check around the Honor 8 forums for the correct files.
A quick summary of what I did:
1) Power your phone off and then boot into fastboot by holding Vol down + Power; as soon as it boots up, plug your phone into your combuter via your usb cord.
2) With ADB running, type:
Code:
fastboot oem relock [COLOR="LightBlue"]################[/COLOR]
NOTE: The '#' should be replaced with your unique unlock code that you obtained to unlock your bootloader.
3) Wait for it to format and reset your phone and go through the setup. BE SURE TO BYPASS all google registration; skip everything you can to get into the phone itself. If you do register, it will reactivate FRP and you'll have to start over again.
4) Turn on USB Debugging and every other setting that enables developer administrative navigation and control just to be safe. USB Debugging being the most important one, though.
5) Restart your phone and boot into fastboot again using Vol down + Power.
6) Unlock your phone again with:
Code:
fastboot oem unlock [COLOR="LightBlue"]################[/COLOR]
7) Once the command is entered, it'll reset your phone once more and - as stated before - bypass/skip all google (FRP) registration.
8) Enable developer options and USB debugging again and make sure that OEM Unlocked is checked and grayed out.
9) Reboot into fastboot mode to confirm that FRP is disabled and you should be able to install TWRP now via ADB.
@Numerics thanks. The thing is, that I can't boot anything. I can't even go into eRecovery. Nor can I flash a stock EMUI 4.1. It just boot loops all the time and I can only access fastboot.
If you can flash twrp..........Install los or other Rom ..................Go back to stock.......you must flash b360 ober adb...... because los is 7.1...............if you on b360 you can usw the rollback for emui 4.1........,..............sry for bad english
I can easily go to fastboot. But I can't flash anything. I extracted the img from the update.app but can't flash. It simply says that it's not permitted.

With my method, you don't need to flash anything. Just relock your bootloader via adb in fastboot mode and let it reset. Unless I'm not understanding your issue entirely.
@Numerics as I said, in won't boot anything as it is constantly boot looping. There is no way to access any kind of recovery nor erecovery. There is no boot into Android. The only thing accessible right now is fast boot (which is not ADB). But even in fast boot I can't do anything als operations are not permitted.
after boot looping and starting fast boot mode, I can see a "Android reboot reason" section saying:
AP_S_PANIC
data is invalid
There is still a lineageos installed on system as firmware but as I tried to get rid of it by going back to stock EMUI, I guess Huawei's rollback did something wrong and killed recovery (although I did it in the past successfully).
I tried to run HiSuite to recover my phone, but it just says, that my phone is not supported.
Speaking of this, Huawei messed up with that whole fastboot locking bull****.

No, I know ADB isn't Fastboot. What I'm trying to say is that you should be able to still run ADB via CMD on Windows when you're in fastboot mode to relock your bootloader with the directions I gave in my previous post. It'll force-restore your phone to a non-bricked/vanilla state. At least that is how I fixed mine.
Like... You can't even try using the 'fastboot oem relock ################' function via the ADB console while in fastboot?
yes boy trust us, you haven't a working OS so it is a normal thing that your phone reboot, you cannot access to recovery because some partitions are corrupted (data partition) , so these are the steps that could help you:
1) using fastboot, relock your boot loader
2)using fastboot, unlock your boot loader (partition table would be ok now, and you would be able to use load method to flash things trow stock recovery)
4)put inside your sd card \dload\update.app(use rollback package)
3) press all the buttons while your device is rebooting(do this before the blue screen logo appear), your phone is now looking for something inside your sd card
5) if the next step doesn't work do a factory reset from recovery that now would be working
6) put inside your sd card a full android 6 (emus 4) update.app and pressing all buttons it will install the firmware
7) your device now is locked and back to stock, maybe without cust partition or maybe in test mode but it is certainly alive
8) do a factory reset and reinstall the firmware
9) your phone is now ok
You don't lock the bootloader via ADB but via fastboot.
As I said, northing was restored and nothing is booting and I can't unlock my bootloader again. As I said, recovery is not working so the file in dload is not loaded and used. Which is strange.
Locking bootloader didn't do anything besides locking the bootloader. Device is still dead and I still can only access fastboot.

This is not the truth.....locking bootloader will erase all your data and fix partitions....and with fixed partition you can access to recovery ......trust me the only thing that you can do is to lock your bootloader......you can't flash anything from fastboot and boot recovery or system now...... lock your bootloader and then unlock it again, try using "fastboot OEM lock *****" or "fastboot OEM relock *******" (try cmd runned as admin, people say that this makes the difference) then unlock your device again and .....magic your recovery will boot......the same thing happened to me and I fixed my phone using this trick, however, even if you had frp unlocked it would say you that isn't possible to write anything because you broke some partition, and that's the reason why you can't boot recovery, wait one second and think: why doesn't my recovery boot?
It has nothing to do with trust. I did it and device is still a full stone brick. Nothing changed by locking the bootloader besides that now I can't unlock the bootloader anymore.
My note 6 pro suddenly started doing boot loop. I tried to revive it by flashing stock firmware but nothing seems to help. It has unlocked bootloader, with TWRP installed. This is what I tried:
Put phone in fastboot mode, I do see the fastboot image.
Computer recognizes the phone. 'fastboot devices' shows correct device.
Using MI Flash tool to flash 10.3.6 global fastboot image. It takes about 160 seconds to flash all the partitions. The phone will reboot at the the end of the flash. Flash tool doesn't say "successful" though. Its status is still "flashing".
No other errors. When the phone restarts, it is still stuck in the boot loop. Interesting thing is, if I press volume + button and power button, I see TWRP flash for a quick second on the screen then boot again. Looks like the recovery image wasn't flashed properly.
Looked at the logs. Nothing strange. Also tried to run 'flash-all.bat' in a command line (not sure if we are supposed to do that), but all the fastboot flash commands look OK.
Anything else I can do to revive this phone?
Good morning!
While attempting to flash a stock MIUI 10 ROM into my Xiaomi Redmi Note 7, to downgrade back to Android 9.0 due to some app compatilibty issue, I messed up big time and my phone is now stuck in a loop where the screen turns on, nothing shows up, then it restarts, going off for a few seconds and turning on again.
Power Button + Volume UP successfully brings me to the stock recovery 3.0 from xiaomi.
Power Button + Volume DOWN fails to bring me to the fastboot mode.
If I select the Connect with MIAssistant in the recovery the phone will show up as "sideloaded" after using the command adb devices, but the MIPCSuite app does not see it and the command adb restart bootloader also fails to bring up the fastboot mode, it just gets stuck in the loop again.
More context on what went wrong and caused this: I followed an online tutorial to flash a rom using the MIFlash app, so I unlocked the bootloader and tried to flash the rom usin xiaomi's tool. I got a failed to check sparse crc error code and it went downhill from there when I tried to fix things reading multiple threads on the issue. I tried deleting some lines from the flash_all.bat file and tried to flash it again but then the flashing process went seemingly forever so I aborted the operation and now this loop happens. I tried a few more times but with no success.
The first time I tried to use the tool I used the clean all and lock option so I'm not certain if the miflash tool locked the bootloader regardless of the outcome of the flashing attempt.
Is there hope? Can I fix this phone if I only have access to stock recovery and nothing else (although it shows up in adb devices but can't get into fastbootmode) ?
Thanks a lot to anyone who took the time to read and possibly help.
Both ADB and Fastboot are Android-side launched by device's bootloader. If you can't enter Fastboot mode then my guess is there is something is wrong with curently installed Android.
BTW: If you lock device's bootloader then bootloader attempts to load device's Stock ROM.

I see.
What can I do to try to fix this issue?
I finally managed to fix it through the Emergency Download Mode (EDL). It requires Xiaomi Authentication which I bypassed using this guide: https://www.droidwin.com/fix-mi-account-authorization-unbrick-xiaomi-edl-mode/
With that setup I flashed a stock rom using the MiFlash tool.
Okay so yesterday I decided to finally try to install TWRP to flash a custom rom on the system, but never thought it would give so much headache. My drivers were bad, the system locked and android 11 updating making the phone all sorts of bugs, I was anxious to get rid of it, and I did somehow. I was unable to flash TWRP into the recovery as the system partition type is different than usual for it seems, but the recovery partition was all weird, "no command" was stuck in the screen even after a hard reset through there. So I got Magisk and got Root and used Smart Flash to install TWRP through the running system and it landed successful. But when going to the recovery the TWRP screen was flickering, but I could send ADB commands yet and boot normally, I just couldn't access the recovery functions yet. So I flashed a different version of the TWRP with the IMG and the zip folder and nothing worked then I realized that maybe I should erase the partition before flashing it and then the murder. I found a tutorial on erasing stuff, but the whole process cost me more than twelve hours as I messed with so many things and was kinda learning the hows and dos.
But then I saw the command "fastboot erase system -w" that was a shortcut for all cleanup processes and I was wanting to wipe it again even to recover my google backup and be able to use my messenger apps. But it did erase, of course, the whole system and everything, simply destroying everything, but yet stuck in the fastboot screen. What I did? Well, I downloaded the TGRZ of an older version of xiaomi mi a3 firmware, the android 10, as I was tired and thought that maybe if I downgraded it I would get my phone to get rid of android 11 bugs and sleep for good till tomorrow, that is today. I ran the script to wipe anything and install the system over it and it did successfully, then the message "successfully installed, press any key to finish" but then the prompt closed and the phone tried to reboot but fell into a hard brick. The computer recognizes the device as the name "QUSB_BULK_CID:0411_SN:EFCF04FD" and the hardware ID "USB\VID_05C6&PID_9008" matches the original.
So is there anything I could do yet? Phone warranty ended in january and that's why I tried that process, it is any worth?

well it seems I recovered it back, I bricked it and somehow it just got into EDL mode without cable or opening it up. So I found a tutorial back on reddit showing how use GFIL to install the stock rom back. I used android 10 stock rom before bricking it, but as I just flashed everything on empty partitions it didn't work, it seems that the Qualcomm setup needs some kind of previous work to set everything up. Anyways I managed to boot it, but now I'm aware that I should use Lineage recovery instead of TWRP as Mi A3 support is lacking, that's why after installing it I got it flickering (no compatible version with the latest Android 11 firmware).
