[Q] Bootloop - no recovery - no system - reset tamper flag - RMA

Hi guys,
my N5 is broken and i want to RMA ... It bootloops at the Google Logo, I can enter Fastboot, but NOT the recovery.
I managed to flash stock via fastboot and I locked the Bootloader.
After that I tried to reset the Tamper Flag with osm0sis' BootUnlocker zip ... well, ya need recovery for that. I tried to boot twrp with
Code:
fastboot boot recovery
but that returns "cannot load 'recovery': No such file or directory".
flashing the recovery works well ... but it doesn't boot into recovery, its bootlooping here to, even if you select recovery mode in fastboot.
So, any ideas how to do that now ?
thanks in advance !
EDIT
AWWW ..... after re-reading my post, I realized the command was wrong ..... its just boot ... not boot recovery ....jeeez
But anyway, even that results in a Bootloop .... so no way to access anything else but fastboot.

it wont boot into recovery. boot into bootloader, then recovery, if no recovery, flash a recovery. btw, dont boot a recovery, flash it. if you run the script to boot it, itll only boot once. you need to fastboot flash recovery recoveryname.img
edit.. i noticed that you are booting a recovery. booting it only works for a one time use. dont boot it, flash it.
fastboot flash recovery recoveryname.img

fastboot boot recovery boots the phone to a recovery image on your PC.
So like fastboot flash...
fastboot boot path\to\recovery.img

I know that booting it is only one time use, I did that on purpose. But it didn't work either, see edit in OP.

the boot command is wrong as well. its fastboot boot recovery recoveryname.img
and the recovery file has to be in the same folder on your desktop as fastboot.

fastboot boot doesn't need you to identify a NAND partition as you're loading it into memory.
fastboot boot recovery.img is the command if your recovery is called recovery.img
The recovery file can be in any directory.
If you haven't installed fastboot correctly, you need to open the command prompt in (or change directory TO) the directory where fastboot.exe is. The easiest way to deal with this is as you say, drop the recovery image there, but you can also just prefix the recovery.img with the path if its anywhere else
However best practice would be to install fastboot correctly by manually adding it to environment variables or using the 15 second installer (or even dropping fastboot.exe in an existing environment variable path such as c:\windows\system32) at which point you can run fastboot no matter what directory command prompt is running in.
I cover most of the above in my "adb and fastboot. What is it?" Sticky thread in my signature
Anyway, sorry OP, I think you're stuck.

Didn't work as in the format failed, or the recovery flash failed?

I didn't see it mentioned but, have you tried a different alternative recovery? I speak from experience at one point after rooting, my phone would not launch the stock recovery. I then tried to use CWM (it's what I was familiar with) and it wouldn't boot either. I then went to TWRP and it did work.
Is it maybe possible the recovery image you have is corrupted or incomplete? Possible maybe you have the wrong one you're trying to flash and boot? I once mistakenly flashed my tablet with the recovery for my phone. Fixed that issue but it drove me nuts for a few hours wondering why it wasn't working.

Didnt work as in it stuck in the same bootloop again ...
no luck with other recoverys or other ..tried several
i only can enter fastboot

Install custom recovery and root on Cubot J5?

I have tried for a few days to install a custom recovery but no luck. Perhaps someone can give me some advice?
I have tried Mediatek (MTK) Auto TWRP recovery porter, version 1.5 but it didn´t work.
This aswell twrp-recovery-cubot-j5-root from getdroidtips but nope...
Chip on phone Mtk6580 and android 9.
Updated to the latest firmware release via spflashtool from cubot own site.
I guess that im to much of a newbie to get this done...
But atleast its updated, my main goal is to root the phone so thats why i need a custom recovery.
Thx in advance, and sorry for my english grammar, not my main language. :laugh:

My dear friend did you try:
https://www.cyanogenmods.org/how-to-root-cubot-j5-and-install-twrp-recovery/
btw why didn't Mediatek Auto TWRP recovery porter work? what was the issue?

I have the same problem the thread starter indicates in the title: I can install the TWRP recovery image that gopikrishnanrmg linked, but the installation of Magisk doesn't work. It says it installs successfully, but I can't get root rights and if I install the Magisk app, it says that Magisk is not installed. Magisk canary doesn't work either. Does someone have an idea what I might have done wrong? Or does that mean that the device is not supported by Magisk?

Sorry for the late answer, life happens
I get it installed with that guide after unlocking flash state, but when it reboots it give me a message "orange state" and the phone resets.
and the recovery porter did not work for me, maybe i´m to old for this hehe was a while since i rooted a device, and i´m defenitly no hacker
btw if you need to look on the firmware cubot(dot)net has a downloadable link for the j5.

I have the same problem and I can't do anything about it, maybe some specific source or a hint in the form of YT

Has anyone figured out how to upload Twrp recovery to Cubot J5 ????

I was able to root Cubot J5.

I tried flashing your files but unfortunately got a bootloop again . I was on the same stock software, unlocked bootloader and tried to flash as you described.

Cause of bootloop.
1. vbmeta.img is not flushed.
2. The firmware version is different.

Thanks for your reply! When i woke up today i thought i can just as well restore the stock rom but found the phone booting.
The boot was just taking way longer because of the factory reset (through oem unlock).
I just installed the root checker and it is working fine!
After years of having this phone and trying to root it you just saved it. Thank you!
Do you have plans to install GSI images on it as well?
*update* i'm able to boot a lineageos 18.1 GSI with your images. I flashed the system and afterwards your boot, recovery and vbmeta and it worked.
*update2* I wanted gApps so i tried the lineageos 19.1 image which was too big. After that i tried an AOSP one with lite gApps.
I think i messed up badly. I can't get back into fastboot and not even the spflash tool is able to flash something. When pressing Volume down+power it briefly detects it but won't write the firmware. I'll try different versions later and report back but for now it's dead
*uodate3* It's back again. I had to re-install the mediatek drivers for the tool to work. After a stock boot i was able to unlock the bootloader and install LOS again. I will go for an image with gapps next.
Thank you again for providing your images and support!

You really helped a lot. I'm always glad to tinker with spare phones.
For anyone else stumbling upon this thread trying to install a GSI image: Here is how i succeeded.
1. Enable unlocking in your developer settings
2. Use "fastboot flashing unlock" to enable flashing (this performs a factory reset)
3. wipe your system partition with "fastboot erase system"
4. Flash your GSI image wizh "fastboot flash system 'path-to-your-GSI' "
5. flash the provided vbmeta with "fastboot --disable-verity --disable-verification flash vbmeta 'path-to-vbmeta.img' "
I had success with lineageos 18 A/B with gapps. Make sure that it's not too big in size or else you will get an error message stating it is too big.
If you have troubles getting into recovery/fastboot, use the SPflashtool to revover your stock firmware (be sure to NOT format all because you will lose your IMEI information in that process!) and try again

Hi,
i tried to root my Cubot J5 by doing the following:
flash system system.img (from CUBOT_J5_9061C_V14_20200506 .zip)
fastboot flash boot magisk_patched-23000_boot.img
fastboot flash recovery magisk_patched-23000_recovery.img
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
reboot in recovery mode
When check for root with root checker basic, systems says, that magisk is crashed several times. And after this root checker states that no root is granted.
Any idea?

Hi, try booting with a boot.img in the same version of your phone.
First, type in CMD fastboot getvar all
Second, Look for the line which states your installed rom version.
Third, Download the same rom and extract the boot.img from the zip file
Fourth, In CMD type fastboot boot boot.img If nothing goes wrong with the download, your device should boot up. Then check to see if you can activate the OEM lock. If not, try updating phone. Does it let you you update? great do it. If it show device system integrity corrupted, wait seven days without turning phone off and try updating again. If still no dice, then you're out of luck.
I had same problem as you, and what got mine back from the dead was to keep updating till one update fixed my issue.

But it still don't work, i tried every other compilation too, excluding the Android 9 ones... I also tried blankflash but did not work.
It gives me error and goes to the "Your device is corrupt. It can't be trusted and will not boot" screen:

Fastboot boot won't work because locked bootloader checks for a key which don't match correctly. You should try same version as the one installed on your phone or newer. Can you boot system?
The only way is to get blankflash to work. Try other computer, preferably older ones with intel, not AMD. If system is able to boot try OTA update because it fixed on mine.

I know that this version (QPI30.28-Q3-28-26-4-1) is the correct one because i had flashed my phone with it before trying to lock the bootloader, and it worked. I also tried every other compilation. I got the .rar from lolinet.
I tried blankflash, it did not work... It still gives me the same error. My computer on a i7 920, so it's very old. Anyways, thanks for any help you might be able to provide.

You should get boot.img from rom and use command fastboot boot boot.img to boot to rom. Then try oem unlock option activating or OTA updating if first doesn't work

Does your device show up as QCOM 9008? It's the EDL state and only way to install via blank flash

You can't do blank flash if it's not showing QCOM 9008 mode on device manager, that's the device EDL mode. I'm afraid that's you only option, aside from opening back glass plate and shorting 2 points in motherboard or using a stripped USB cable and shorting green cable to black cable

Idk the points in motherboard so best way is to use cable method or buy an EDL cable online or use a "box" which flashes directly through JTAG but that is expensive. Just leave the green and black cables connected for 8 seconds if nothing happens try again this time for 20 seconds

no, its like when i do "fastboot boot boot.img" too many times, and when i do a blankflash it goes to that your device is corrupted screen.

The EDL should have worked... Well your last bet is on the box JTAG flasher. You'll either buy it and learn how to flash or ask some professional to do it

I keep researching and every video that shows what to do or posts, i can only get so far before my results dont match and there is no option or description for what to do if getting an error.
edit: adb devices shows nothing, but fastboot devices shows serial.
TIA

I think you have the wrong drivers, try these and check in windows update if your Qualcomm drivers are up to date in the optional updates. Also if fastboot is working and the bootloader is unlocked, you can download the latest full oos 12 and flash it all.

and continues with this error for what ever its trying to flash "has slot all"
flashing logical patitions error:
no such partition or partition not found
I keep researching and every video that shows what to do or posts, i can only get so far before my results dont match and there is no option or description for what to do if getting an error.
edit: adb devices shows nothing, but fastboot devices shows serial.

can not get phone to edl stuck in fastboot only. tried all the commands and physical button configs and still only get fastboot. Any workarounds?

I downloaded Fastboot Enhance, which allowed me to flash a bin file, but the phone still wont boot. I had to check ignore unknown partitions for it to flash. Now i can access fastbootd and when choose boot to recovery it loads what looks to a limited recovery similiar to fastbootd.
Any advice?

Run the MSM tool in edl, since now it should work fine. Also did the drivers work? If not you need to uninstall them in windows device manager, then reinstall them

Well, you've never said in your initial post what it was that you were trying to do.
Now that you are in the stock recovery you can select Advanced> reboot fastboot.
This will put you into fastbootd mode where you can do things like flash partitions and, more importantly, flash the logical partitions.
But, if you don't know how to do this and get out of whatever mess you're in , then use MSM Tool to reset your phone.

I just reread my initial post, damn I started typing mid thought.. my bad!
I tried msmtool, but it doesn't load up a com port. All the listed methods with holding both vol buttons after already hitting start then plugging in did not work as I don't think it sees it at all.
Haven't found a thread with fastboot instructions that didn't require something I couldn't get to, to restore the phone. other methods fail writing to numerous areas when flashing.

OK was able to execute the first 4 fastboot commands, the it hung on the first flash --slot=all
In the end i just boot the phone in fasbootd using fastboot enhance and then using the flash bin file option in FE to flash the OOS 12 FILE @Nimiskiv shared.
Final boots into OOS, hope all works I will be testing to see for a day or two before i switch back from the 6, also before all this the 8T went a12_c11 to a12_c33
right now update for c20 came up!?
Any additional insight or final thoughts appreciated. Thanks again all!

check if EDL is working now, its very important for edl to work, because if something happens in the future, you need edl to reset.

Trying to fix corrupted boot file on oneplus 8 5g in2017 tmobile model (FIXED)

sorry if this is not the right place to ask this
After unlocking my bootloader i tried to flash twrp on my phone by using the command "fastboot flash recovery twrp-3.7.0_11-0-instantnoodle.img"
When i restarted the phone it got stuck in a bootloop
I've been searching for a way to fix it for hours now, but everytime i do something it feels like i make it worst, now my phone is showing me an error that reads "the current image(boot/recovery) have been destroyed"
I dont know what to do, please if you have an idea of how to go forward reply

It's telling me to get a "download package". Do I have to pay for this?

First, are you sure your device bootloader is unlocked?
Two, are you able to enter fastboot menu?
Three, if you can enter fastboot, try to BOOT into twrp instead of FLASH
Example: fastboot boot twrp.img
Booting into TWRP is the instructions for the OnePlus Pro 9, maybe it may work on the 8?
MAKE SURE OEM lock is removed first!!!

Has old firmware you can download / flash. You can use a tool called Payload dumper on the firmware to extract all the sections and re-flash the sections you messed up. Can you get into the bootloader / fastboot screen and show me what it shows?
Re-download the twrp file for your device, rename it to twrp.img and try to do this command
Make sure you also have the correct drivers installed on your pc and disable driver signature enforcement:
fastboot boot twrp.img

Ok the fact you can enter into this mode and it says device unlocked is good. I am not sure why it doesn't allow you to boot with the above mentioned command into recovery.
Please make sure like I previously mentioned you have latest platform tools, latest oneplus usb drivers and try to switch to a usb 2.0 port on your pc or laptop. Disable driver signature enforcement in windows before you try to install oneplus drivers.

I've should have mentioned this earlier but i'm doing most of this on a linux machine, but i have repeated the commands on a windows laptop doing everything that has been mentioned previously to similar results
Now when i try to boot Twrp it just hangs and no changes happen on my phone
.\fastboot boot twrp.img
Sending 'boot.img' (67276 KB)
and then nothing happens
When i try to flash recovery it also hangs
.\fastboot flash recovery twrp.img
and no response
I'll try this with a different cable and update this post

I think you corrupted a bunch of stuff when you used a linux machine to flash a recovery. The drivers are vastly different on a linux machine. You might have to use a MSM tool at this point, but I am not sure if the T-mobile version has one. Keep us updated on the new cable. Also try different usb ports as well.
Which android version did your phone have? I checked the official twrp website and it only supports A11 devices for oneplus 8.
@Provenscroll EDIT: I was just testing different slots a/b on fastboot and realized that when I changed to slot a, my inactive slot, I get the same error as you did with fastboot. Try to use the other slot if possible.

So i tried this and it successfully flashed:
.\fastboot flash recovery_b twrp.img
Sending 'recovery_b' (67276 KB) OKAY [ 1.638s]
Writing 'recovery_b' OKAY [ 0.212s]
Finished. Total time: 2.093s
When I reboot into recovery though it just ends up at the boot/recovery error

Yes I would try it on A11 first. But don't quote me on that because there is a reason I don't like using carrier based phones instead of fully unlocked phones. They come with unpredictable problems. Try at own risk. I would first try to boot into TWRP first on a11 firmware and then flash TWRP recovery with the option: "Install Recovery ramdisk" then select the .img file you downloaded from website. You can also use: Go to Advanced > Flash Current TWRP.
But the problem is: you need to be able to BOOT first into the recovery.
Heck I would try to boot with the a11 twrp right now just to see if it loads instead of using the flash command, if it boots up its a good sign but it probably won't have decryption support, all your files will look like random numbers. Your bootloader is unlocked so common sense dictates it should be able to boot the twrp.
Fastboot boot twrp.img
EDIT: Well I tried to boot unofficial a12 twrp onto my device and it didn't boot into it. So it might not work for you either. I am on stock oos 11 and the a11 version is the only one that boots.
This link might be able to help:
https://forum.xda-developers.com/t/...p-for-oneplus-8-8pro-official-beta-3.4341707/
I noticed at this link, they have different .img files then the official website. Give it a try. They mentioned flashing instead of booting, so it's slightly confusing.

Ok so I tried flashing a boot.img file I extracted from a payload I got from here

OxygenOS 12 Open Beta builds based on Android 12 have begun rolling out to multiple OnePlus smartphones. Head on over for the download links!

and now theres a recovery screen:
I tried using format data to see what happens since my important data is already backed up, when i did this my phone rebooted into a setup screen but when i get to the point where i have to setup my network the screen hangs and the phone restarts. Maybe this is because the roms model number doesn't exactly align with my phone?

I got it in twrp!!

Ok I am not sure what you should do at this point: flashing the recovery while in TWRP or simply booting into it future wise. I read on t-mobile devices, if you try to flash it might brick it but I am not sure.
