Recovery verified failed ??

Hello A510 owners,
After playing with patching google store using lucky patcher, my tablet start to bootloop...I was on Piccolo Rom,so I just flashed the rom again (wiped everything that could be wiped), but didn't worked, still bootloop...So I said to myself, let's make a fresh and clean install and get back to stock. I've download a stock rom, put it on my external SD Card and flashed it in CWN. I got a warning like I won't have recovery anymore after flashing but accept anyway, and start to flash...Tablet reboot and this is what I get :
Code:
erasing cache before sd update
SD update cmd : recovery
--update_package=SDCARD : update.zip
booting recovery kernel image
[COLOR="Red"]Recovery verified failed[/COLOR]
Then, I tried many stock rom I could find on the internet, still same error. I even tried with removing first line of the updater-script, nothing work...and I can't use adb anymore to push cwn again.
Any idea ? I really need help here ! :crying:

I guess u might flash the stock n still kept the cwm, so u can't enter the cwm anymore 'coz the bootloader was locked back.
Maybe u can try to unlock first, or u can consider to rewrite the recovery partition.

Rename update.zip to something different, CMW may not accept "command line" flashing.
Anyway if you can boot CMW (rename update.zip first!)
a) wipe dalvik-cache (under Advanced) and try to boot
b)if this fails- wipe data/cache (factory reset)

THX guys, I don't know how but I just format everything and reinstall cwn+rom, and it worked... I just lose all my datas on sdcard:'(

I cannot flash TWRP or any Mods

I just got this phone and i have OEM Unlock enabled. I am due to sell my old phone in few days so i am in a bit panic mode right now :\
When i try to flash TWRP along with the instruction that were here (i tried with only applying both or only dm-verity) the phone started to "start" flashing the Samsung logo but nothing happened and after 15-25minutes i tried to install this ROM and it also shows "Starting up please wait" but it also seems to start up indefinately.
Can you tell what is wrong now? It seems i can flash the stock ROM and boot to it but cannot install TWRP/Root nor any custom ROM's :\

Hey bro follow this.
Install stock ROM.
Boot into it once.
And flash TWRP. Disable auto reboot in Odin.
Then boot into TWRP directly from there.
Now swipe to allow modifications.
THEN GO INTO WIPE ADVANCED WIPE AND CLICK FORMAT DATA AND TYPE YES.
After format reboot into recovery once again.
Now again swipe to allow mods.
Now only install Dm-verity.
Reboot.
Now the phone will boot.
Go back into recovery to install your ROM it'll root the phone.

Sorry but still no dice (waited for ½hours to boot)
The data wipe did not even succeed. I attached screenshots of data wiping plus no-verity install if there is something anyone could use. I do not really understand how this is so hard... I have never encountered this kind of problem with common phone.

@DARKKi
Did You try to format data or just to wipe? You should click on format data and type "yes"

Dude I clearly mentioned, you have to click format data in advanced wipe. First try to read and understand then proceed. Click format data and then type yes and then you're good to go.

Damn. Sorry, i think that when going into advanced wipe there is no format there it's under normal wipe so i only thought that it meant that but yeah my mistake. I should have looked for format data and come to my own conclusions :\
Well first result of format resulted on loop boot and i could not even flash the stock rom with Odin (failed directly) but then i tried to flash TGP ROM via TWRP and it worked! So now i am using the phone as we speak!
Thanks a lot njaya95!

Sure no problem, I'm sorry about misleading you about that format data. Have fun with your phone.

Which "Advanced WIPE" options in TWRP for "best" factory reset?

Hi everyone!
Yesterday after entering boot loops after trying to install the Xposed module from Magisk, I reinstalled the latest Oxygen OS zip via TWRP's "Wipe / Swipe to Factory Reset". When the phone booted in "hello, new user" mode, I saw there were still files from before under sdcard/, so, to be sure, I also tried to do a Factory reset from within OOS Settings / System. When the phone booted in "hello, new user" mode, I noticed there were still files from before under sdcard.
I re-flashed Magisk, installed a few things, did a backup via TWRP. Worked on setting up the phone for two more hours (didn't install any Magisk module, only software from the Play store), rebooted the phone to check everything was okay… boot loop!
Using the backup, I was able to reset the phone to the state of before wasting these two hours… But these boot loops seem so fickle, so random, that I wonder if I'm missing something with the factory reset, if maybe there is a more brutal reset that would erase all trace of activity after the state where the phone was after unlocking the bootloader.
Is there a way to do a more complete "factory reset" than what I've done? I see that Magisk has an "Advanced Wipe", if I checked all the box would that do it? Or is that a bad idea because some important OOS recovery files would vanish. Which "Advanced Wipe" options should I check? If I follow that procedure, will I be able to reinstall TWRP and Magisk via ADB?
Really needing some expert insight, I feel very lost!
Thanks in advance!

Hello, format internal storage within twrp deletes everything off your /sdcard but does not touch system, data, vendor for example.
You're still able to use fastboot/adb cause you do not delete the bootloader:good:

Thank you for your reply!
Just to be sure I understand, are you suggesting that a strong way of getting a good Factory Reset would be:
TWRP / Wipe
[ ] Dalvik / ART Cache
[ ] System
[ ] Vendor
[ ] Data
[x] Internal Storage
[ ] USB Storage
then (if TWRP is gone):
adb devices
adb reboot bootloader
fastboot boot twrp-3.3.1-52-guacamole-unified.img
In TWRP, install twrp-3.3.1-52-guacamole-unified-installer.zip
In TWRP, install OnePlus7Oxygen_14.E.14_OTA_014_all_1907280716_7e28877dd39949e3.zip
Do the phone's "Welcome, user" setup
Flash Magisk
Does that sound right?

Generally the factory reset does all too need(from android settings). Why theres something left of your device I don't know.
But I meant format internal storage, not wipe internal storage.
So reboot to twrp - wipe - format and follow the instructions reading the hints.
Again: that does not wipe your twrp, system, system data only the internal storage like music, photos etc.
For installation, it's OK what you wrote

Thank you very much, @strongst.
If I understand, that "Format" option that you suggested is what gets rid of all the personal files. Then to Factory Reset, I can either flash via TWRP, or use adb.
At the moment I am thinking that like you suggested the phone is actually okay after the standard Factory Reset — and that the earlier boot loop was created by one specific piece of "bad software". So I am reinstalling things little by little, and doing TWRP backups after every 15 minutes of set-up. That way if the phone enters a boot loop, I will be able to restore and to narrow it down, and check on the forum if others have the same problem. Does this make sense to you?
Wishing you a great week!

It's a good way to break a potential boot loop issue down, time consuming, but worth the effort in case it boot loops

Bootlooping to recovery after flashing Custom rom

I unlocked my phone yesterday and installed orangefox recovery in it. However after flashing custom rom, it keeps rebooting back to recovery. Have no idea how to solve this. Any solutions?

Tried that. not working. Also if its relevent system, vendoe, etc are not mounted. only data, cache, and microsd is mounted. Have no idea why.

Me too faced this kind of issue, peter's TWRP worked for me, follow instructions from here

Ok It worked. No need to flash the dm Verity for orange recovery. What I did was simple.
1. Factory reset (Did this step before also)
2. Format Data (Also Did this step)
3. Flash rom (Of course did this too)
4. Then reboot to RECOVERY again, not to system. (did not do this step before). Go to reboot part and click reboot to recovery, not to system.
5. After that reboot to system and it should work. Mine did.

Solved
I to had same problem but mine worked after installing custom ROM install FCrypt disabler.zip from recovery then reboot and enjoy.
Download FCrypt disabler.zip for Redmi note 7 Pro from Google.

Flash any zip which disables dm verity things. Suggestion: flash lazyflasher zip.

[Solved] Help to flash custom ROMs

Hello everybody,
I bought a Oneplus 7 Pro a few days ago and I'm preparing it for my daily usage. It's my fourth Android smartphone, and the third Oneplus. So far, I managed to flash everyone of them, with no major issues.
And then, the Oneplus 7 Pro suddenly appeared
I used this tutorial to unlock the bootloader and flash the custom recovery.
From my understanding, the custom recovery is flashed in the Recovery Ramdisk and available for both A & B slots.
For now, I have A and B slots with stock OSS, unlocked bootloader, custom recovery and Magisk. All of this is working.
There began my problems. I want to flash a custom ROM without Gapps and I fail to do it. All instructions around ROM threads seems different to me, I don't get the thing about A & B slots, when I flash one rom, it boots as usual on the stock ROM, if I flash both slots, It causes bootloops and if I manage to launch the recovery, my internal storage isn't detected and I can't restore any backup.
I already used MSMDownload to restore the phone completely once.
Can somebody explain to my dumb person how to do it proprely ? Thanks in advance ! :fingers-crossed:
TL;DR : I fail to flash a custom ROM and make it work.

Yes I had same issues when rooted, it means you lost root. You can try tool all in one to flash recovery and magesik via fastboot. If that doesn't restore your access, on twrp you will have to type in format, then mount, then add rom to storage(this method wipes everything beware)

For now, my phone is working nicely. But that's the process of flashing a new ROM that fails. Recovery and Magisk are already and working.

Reboot recovery

Thanks, I will try.
When you flash the ROM, does TWRP tell you that if you want to continue you need to reboot recovery ? If so, do you ? Do you reboot recovery on the same slot, or do you flash both ?

Nope, it doesnt tell you anything. Just reboot recovery from reboot menu. Don't touch the slot options

Thanks for your advices.
I'm trying right now, here's my steps :
- Wipe Data, Cache, Dalvik Cache (the standard Factory Reset)
- Install ROM : TWRP logs show that he's flashing on inactive slot A, then B. After that logs said " To flash additional zips, please reboot recovery to switch to the updated slot ". I'm going back on the menu
- Install TWRP Installer like previously
- Reboot Recovery : TWRP ask me if I want to install the TWRP App, I dismiss. After reboot of the recovery, it asks if I want to keep System Read Only, I swipe to allow modifications
- Wipe Data : Can't do it because TWRP is unable to mount storage. And after further investigations, I'm now on slot A, not B as before.
- Reboot recovery to slot B
- Wipe Data on slot B
- Reboot system
And It still booting on the stock Oxygen OS Rom, not the custom one installed before. I'm lost

The problem is that you are not performing factory reset.
Wipe data is not enough,you gotta go to wipe-format data-enter yes and swipe.
That is why you are getting bootloops and twrp unable to mount storage problem.
A/B is pretty simple.
You got two slots for many partitions like system vendor boot and all,but a single data partition.
Flash a rom from one slot,it always gets flashed to the other slot no matter what.So next time you reboot to recovery or system it's gonna be on the other slot.So here is the problem..one rom cannot decrypt data which was initially encrypted by another rom..so you gotta perform a data format instead of wipe.Thats it.

Well yes, I didn't understood the difference between Wipe and Format Data.
So let's resume :
Unlock Bootloader
Advanced -> Install Recovery Ramdisk : Install TWRP
Install -> Flash TWRP Installer
Install -> Flash Magisk
Reboot -> System : Reboot on stock OxygenOS Rooted
Then
Wipe -> Factory Reset : Wipe Data, Cache and Dalvik Cache, that means you just have to swipe on TWRP.
Install -> Flash ROM : Use the install function and install the ROM
Install -> Flash TWRP Installer : Don't reboot, go back and install as the previous step
Reboot -> Recovery : Reboot TWRP and it automatically load the other slot
Wipe -> Format Data : Click and type yes
Reboot -> System : Just reboot and it should load the installed ROM

is wiping internal storage compulsory?

Not wiping.. formatting..that is compulsory if your current data is encrypted

After multiple tries to verify the process :
Wipe -> Factory Reset + : Wipe Data, System, Cache and Dalvik Cache
Install -> Flash ROM : Use the install function and install the ROM
Install -> Flash TWRP Installer : Don't reboot, go back and install as the previous step
Reboot -> Recovery : Reboot TWRP and it automatically load the other slot
Wipe -> Format Data : Click and type yes
Reboot -> System : Just reboot and it should load the installed ROM
Install -> Magisk
Reboot -> System
Install -> Whathever you want
Reboot -> System
It worked !
