Hi all
i am selling my mediapad x2 and thought i would incrypt it before resetting for security.
after 3 hours it was still on the boot logo so i knew something was wrong. i unplugged it and held power for it to reboot but it keeps going back to the same stuck boot.
i cant access recovery no matter what i do. it will get to a recovery type screen but all it says is software update failed.
what can i do?
thanks
You have to use adb on your computer, with your device pluged in fasboot mode. (you'll find many sites about adb fastboot).
Select the rom you want to put on your device, download it. Use huawei upadte extractor to get .img files from update.app file. Then you'll fastboot flash the img files with adb.
You'll find many exemple on this forum by searching "brick" as a keyword
Had a bad idea this morning and decided to try to root the phone, leagoo t5. The last time Im going to go messing with a phone that wasnt broken! after spending 10hrs trying to sort it! I downloaded adb tools and and twrp. I unlocked the bootloader with fastboot and installed twrp. However when I rebooted the phone it just booted straight into twrp. I cant get it to boot normally. I reinstalled the firmware but it will still not boot. I can get into recovery and factory modes but thats it. what can I do? Thanks

Have you tried factory resetting in recovery?

Yes I did. No Joy. When I power on I just get the leagoo logo coming on and off repeatedly. Pressing the power button then will not turn the phone off again. I can switch it off by pressing vol- and pwr together though.
Is the problem caused by unlocking the bootloader with fastboot or that the firmware I installed is not suiting? Rebooting the phone after unlocking the bootloader before reflashing the firmware caused the leagoo logo to come on and off repeatedly accompanied by this message in very small text "Orange State - Your device has been unlocked and can't be trusted, Your device will boot in 5 seconds". After flashing the firmware with Sp Flash Tool this message is not being shown. Does reflashing firmware undo the action of unlocking the bootloader?
What your are describing is a bootloop. It sounds like the device can not find the system kernel to boot to. Did you boot the device after unlocking but before doing anything else?
Where did you get the TWRP recovery from?
Isn't this a mediatek chipset? If so, I think you need to use SP Flash Tool*to install.
I would look for a stock ROM for this device to revert to.
I'm not experienced on mediatek devices, but maybe @SubwayChamp could help.

Then to unlock bootloader is not normal that Android refuses to boot normally but when you flash a custom recovery or modify other partition this usually could happen so either or both you have to do a factory resetting/format data as @ktmom said or/and flash a kind of DM-verity for your device, this last avoids that bootloader checks the integrity of the partitions and can boot normally to system.
The warning message is normal then to unlock bootloader and reflashing the stock rom doesn´t relock it, you have to relock it at similar way that you unlocked it via fastboot command, most commom is "fastboot oem relock" but there are other variants and keep in mind that you have to return completely to stock before to apply it.

I relocked the boot loader with the command "fastboot flashing lock". small white text dialogue on phone screen stated bootloader was locked successfully. rebooted phone then and it was still stuck in the boot loop. For a few seconds in between the leagoo logo a strange circular graphic was displayed on the phone with word "erasing" under it. What does this mean?
Can you tell me more about how to flash DM-verity?

Ok, then to relock bootloader I guess that you did successfully boot to system again, right?
When you unlocked bootloader first then device is formatted to avoid a new user can access to the user´s data and when you relock it again the same happens.
As for DM-verity, newer devices strictly since nougat can´t boot to system after any partition was modified like happened when you flashed a custom recovery on it, here is when DM-verity can be useful, is used to avoid bootloader checks the integrity and allow a modified device can perform a reboot and more custom actions not officially permitted. You had to flash it through a custom recovery, sometimes flashing only Magisk is enough but not always.
You *might* be able to use this universal dm-verify script. It can be flashed only in a custom recovery and I'm not certain that is available to you.

Good news and bad news! I got the phone to boot! I reinstalled twrp and the "magisk","no verity opt encrypt" and "disable dm verity" zips from the ext sdcard with fastboot. Twrp stated the zips installed ok but there were also some red line failure lines in the dialogue as they were being installed. I rebooted the phone via fastboot but this just resulted in it booting direct to twrp as before. I tried normal boot from twrp but it still booted straight back to twrp. I then tried selecting normal boot from the fastboot, normal, recovery option menu accessed on the Leagoo T5 by powering off the phone and then pressing the pwr and vol+ buttons together but this still resulted in it booting straight to twrp. I then decided to uninstall twrp by flashing the stock firmware recovery image to try to boot from stock recovery. I did same and rebooted from fastboot and it booted to system.
The bad news is there is an imei failure message and the sim is not connecting to the network.I googled imei failure and saw that its can happen when firmware is changed. I installed the "mobileuncle" app but according to a youtube video I watched, when I tap "Engineer Mode" there should be 2 further options available, one being MTK Mode. I am only getting one option "Engineering Mode (Android) which when I select just results in being returned to the previous menu. please say this is not a major problem!
@pcfreeze you quoted me, but as I said earlier, I'm not experienced with mediatek devices. You'd be better off quoting @SubwayChamp

It could be many reasons why device didn´t boot to system. Then to flash it you had to format data + flash DM-verity. Also is possible that this TWRP version is not completely suitable for your device or is unable to mount/unmount partitions correctly, you have to check from where you downloaded it and if some users are experiencing similar issues with it.
As per you IMEI lost, better is ever take a backup of the NVRAM through TWRP before to go further then it´ll be easy to recover it. In almost all firmwares for mediatek devices you´ll fnd inside the zips SPFT and SN Writer that is to recover your IMEI. Your IMEI is not really lost only got actually covered by blank codes due to a bad/incorrect flashing/wrong sequence firmware, so be careful what you do with Mobile Uncle tool if you´re not experimented with otherwise you´ll lost permanently.

I got into engineering mode via dialer code. CDS option was missing from connectivity. I installed https://m.apkpure.com/cds-mobile/com.doubleapaper.cds.cds_mobile but CDS is still missing from engineering mode

Sorry, just realised that this is the wrong app! nothing to do with cds in engineering mode! I triedhttps://apkcombo.com/common-data-service/com.mediatek.connectivity/
but got message that the file was corrupted and it would not install
So, I tried to install LineageOS 17.1 (unofficial) on RMX1911 Realme 5...
After successful flashing I forgot to install gapps which was compulsory for me. So back then, when booting to TWRP recovery I was greeted to a fastboot screen but after few seconds it rebooted back to system. As usual I tried to flash TWRP recovery using adb fastboot command on my pc but nothing happened... it still appears the fastboot screen... But during flashing recovery.img, I accidently deleted boot.img and there was no recovery also. Now a screen appears saying that "The current image (boot/recovery) have been destroyed and "can not" boot, Please flash the correct image or contact the customer service to fix it." Also fastboot mode disappeared and cannot boot to fastboot mode. But edl mode came to rescue (cause it's a qualcomm phone). I tried flashing stock firmware using MsmDownloadTool on edl mode but I can't flash because that flashing tool needed a username and pass (which i don't have). Now I rushed to the customer center to fix this but they said that there was no "global firmware" thing on my country (I live in Bangladesh)
Please help me with a solution because this device (Realme 5) is one of my favourite phones.
Looking forward for the developer's reply. Peace!✌
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.
I tried installing the pixel experience rom and after I flashed the aex recovery before side loading the ROM, it went into bootloop and ended up with the stock recovery and ROM. I tried to flash TWRP recovery and go a message that the the boot/recovery image is destroyed so I tried to flash the stock boot image back and since then I am not able to get it out of fastboot mode.
I tried everything, flashing the recovery again, both stock and TWRP and also tried using the flash-all to flash the stock ROM back but nothing seems to be working.
When using the flash-all, I get 'partitions not found' and 'flashing is not allowed in critical partitions' error.
I even tried msmtool but I am not able to get my phone into edl mode for the tool to detect it.
Tried holding the vol+/vol- and connecting the usb cable but to no vain, the tool does not seem to detect it.
I even tried using the all-in-one tool but my phone is not getting detected when it is turned off but it gets detected when it's in flashboot mode from where I cannot enter edl.
Let me know if there is anything I can do to fix it? Or if taking the phone to the official service center help?
Can you reboot from fastboot to edl by entering fastboot reboot-edl? Or similar, don't know exactly anymore
Alternatively see if this can help you getting into edl: https://forum.xda-developers.com/t/guide-how-to-reboot-to-edl-from-fastboot.3394292/
