Hi There, Can someone PLZ help me setting up OPPO PRELOADER Drivers correctly. Everytime i try to use miracle thunder i get the following log:
Waiting for USB Port...
Set USB Serial Device (COM9)
Connecting to Phone,Wait..
Connected to Phone.
CPU: MT6771 SW:0000 Ver: CA00
>>Downloading Boot8 ...
and it remains on here forever.
Actually oppo preloader shows for some time in pc and after that it goes away and hence it is not letting the miracle thunder work properly (i guess)
when my phone was working (booting in coloros 6, then also oppo preloader was doing the same thing and after a few seconds my battery would start charging), now i can't see anything on screen as it's bricked now.
Preloader doesn't even work with SP Flash Tools also.
EDIT : I have tried almost everything i knew, drivers manager add legacy option etc.
If someone could help me get out of this problem, i would really be grateful.
Brick Reason : Flashed TWRP but used fastboot command to boot into that : (

Which recovery are you in? Is it Stock or Custom?
If u have stock first wipe data and then flash boot.img or ozip file (stock ROM).
If u have custom recovery then you need to flash stock recovery + stock ROM.

If recovery and fastboot are inaccessible means you need to visit service center.

Yes. Do remember you need both fastboot and recovery to be working, so you can flash Stock Recovery (only if you have TWRP installed).
If you have stock recovery installed then download stock rom from official Realme site and place it in the Sdcard (otg wont help). Enter into recovery and update/install the ozip.
If your phone is completely dead then above method wont help and you have to follow another one.
Note: If your device is rooted then installing (from stock recovery) stock rom fails. At this time flash TWRP from fastboot then flash zip file (convert stock rom from ozip to zip).

Download stock recovery.
Enter fastboot mode using Power + Volume Down. If that does not work use other combinations.
Now flash stock recovery.
Enter recovery using
Code:
fastboot oem reboot-recovery
Install ozip.

Dead boot Android!

Hello!
I accidentally flashed wrong boot image on my phone via twrp and then I tap on reboot/system after that phone didn't boot.
No response.
Not turning on even I reinsert the battery!
No going to fastboot or Recovery mode!
SP flash tool didn't able to flash rom.
It always shows error.
I think I need to re-programme emmc chip?
Boot information stored in emmc right?
Is it ok/right?
Or is there another method to revive it?

Just reflash the Stock boot.img via fastboot if available.
Or Flash the whole stock ROM via TECHNO FLASH TOOL it is the only Flash tool compatible with TRANSSION DEVICE. Sp doesn't work... And make sure you have installed proper drivers

*Preloader USB VCOM

[SOLVED] Doogee S88 Plus reboot loop with magisk root

after patching boot.img with Magisk and flashing over the patched boot.img, the phone (Doogee S88 Plus) will just infinitely reboot after the message `Your device has been unlocked and can't be trusted`
luckily, patching the original boot.img back fixes it (albeit flashing it back is kindof tricky, have to reboot multiple times while holding down the volume-down button before i can re-flash)
so it's not bricked, but i haven't been able to root it either, any suggestions?
fwiw, i'm using this firmware: https://drive.google.com/drive/folders/13bxhk-eEsJ81FmJWZaEEsOkZBMsYJE3x
update: finally managed to root it, the final piece of the puzzle was that S88 Plus wanted the magisk-patched boot.img signed with the publicly-available-private-key from https://forum.hovatek.com/thread-35862.html
screenshot:
https://imgur.com/EbjK0qX
the magisk-patched + signed boot.img if anyone is interested:
where boot.img ?
and you chose which twrp ?

i did not use twrp at all, i only used magisk, and the boot.img is the file i uploaded above with the name "magisk_patched-23000_TY62U.img" , just rename it to "boot.img"
does your phone has a vbmeta.img?
It control if the image is signed, if you don't flash an empy vbmeta.img the system will bootloop.
It was a problem when rooting the Ulefone Armor 8-11
root is ok , flash tool, install boot and reboot

interesting, yes the phone has a vbmeta.img, and no i did not patch the vbmeta.img, and i did experience the reboot-loop, but signing the patched boot.img fixed the reboot loop without touching the vbmeta.img
This did it..dont flash vbmeta...the Boot ist the only Thing you Need...flashing vbmeta will end in bootloop...maybe a signed vbmeta...but why trying when Boot is enough...
after hours of trying I finally got it working.
Because I tried so much stuff I'm not exactly sure what was the key.
The signed boot.img flashed with sp flash tool alone did not work - i did not have the device unlocked with fastboot at that moment.
Then I tried a lot of different stuff.
I _think_ what was needed is these two things:
- signed boot.img from @hans henrik
- unlocking bootloader with fastboot (fastboot flashing unlock && fastboot flashing unlock_critical)
How did you unlocked it? And are you running gsi rom?
I have the s88 pro and i like to install custom rom
the doogee s88 plus should support galileo GPS standard Pu on mine it does not show any gaileo satelites. could anybody check?
Hi please help me i have doogee S88 plus and i use this guild https://unofficialtwrp.com/twrp-3-4-0-root-doogee-s88-plus/
now me phone keeps restarting, show "orange state", logo launches, I tried different combinations of buttons but nothing helped
what can i do or is there any way i can get it back to normal?
only now found this thread, currently the phone has a bootloop after these three commands
fastboot erase userdata
fastboot flash vbmeta vbmeta.img
fastboot flash recovery recovery.img
OK, i use sp flash tool but when i turn on me phone i see a bars on screen
i tried with all the stock roms i found, everywhere the same, the phone seems to work but instead of images there are stripes
this rom worked
OneDrive
onedrive.live.com
I finally managed to root my phone after days of endless boot loops (fixed by flashing stock using SP flash tool). Turns out I didn't need to flash an empty vbmeta or install TWRP at all. I was able to root it by following this guide https://www.hovatek.com/forum/thread-35862.html. For some reason your patched magisk image didn't work on my S88 Plus, so I made my own using the stock boot image from the official Doogee website (which appears to be the same one used in your patched version?) and Magisk 25.2 apk. For the Hovatek guide, I used python2 since python and python3 did not work. I currently have a red "Not Verify" watermark and an NVRAM WARNING: Err = 0x10 wifi network error, but should be able to resolve those with root access from guides I read earlier.
I would also like to install a GSI (lineageos preferably) but have had no success since nothing seems to officially support the S88 Plus even though it is project treble compatible, and I have ran into boot loops so far.
I have attached my working magisk_patched.img but would recommend building it from scratch using the linked guide to avoid any issues.

Redmi 9 hard brick, bootloop and CAN'T ACCESS FASTBOOT

I was trying to install TWRP using fast boot. At first I was using the usual commands,
fastboot flash recovery twrp.img
fastboot flash (some command) vbmeta vbmeta.img
and it would just boot directly into the system (twrp wouldn't work)
then I did it again but I added
fastboot flash misc misc.bin
And now my phone is stuck in a bootloop. Whatever I do it just goes to the Redmi logo screen, then turns off, and turns on again by itself. (I can't even turn it off)
I say this again: I cannot access fastboot. Is there a possible solution to this or is the phone gone for good? (OEM unlocking was unlocked, I'm sure of it)

Xiaomi MI Flash Tool can flash in fastboot mode or EDL mode. consider deep flash cable.
edit: misc partition is mediatek. erase misc partition from mtkclient
there is a (paid) Xiaomi Pro Tool v3.8 for mediatek on post #28

I think I have the same problem after downgrading from 13.0.5 Miui 13 CN rom to 11.0.4 Miui 11 Global rom. Lolz
I'm already on the part where I can bypass but I can't proceed to downloading the firmware to my phone w/ SP flashtool because my Redmi 9 keeps on bootlooping everytime it connects
In your case, were you in point where you need to open the backcase of the phone so that you can manually remove the battery so that it doesn't keep on reconnecting during flashing?

The timing is a bit tricky. Just keep doing it, it'll eventually connect in the right time and stop bootlooping.

Yep you're right! timing is essential, I actually have fixed it and not needed to open the back case to manually remove the battery. I just tried another port, waited until it stops bootlooping after the bypass and followed those succeeding steps again.
But...
After successfully flashing with my stock firmware and updating it to MIUI 12.5.6 Global. It seems the bootlooping wrecked the hell out of my battery and I'm always suffering with occasional reboots everytime I maxxed out the volume and whenever I tried to call. Seems my phone is getting weak current or battery supply, sucks.

Doogee S88 Pro infinite loop can't access Recovery Mode

Hi,
I flash unnoficial twrp into my doogee s88 pro using this command
Code:
fastboot flash recovery twrpname.img
Then I dind't flash Vbmeta and now my doogee is in infinite loop (is restarting all the time) and I can't acces to recovery mode pressing volume up + power either volume down + power.
I tried to connect to PC to send fastboot commands but doogee is in automatic reboot all the time and I can't send any command.
In the screen appears:
Orange state
Your device has been unlocked and can't be trusted
Your device will boot in 5 seconds
With SP Flash Tool I can format whole flash and now I'm try installing a ROM stock with SP Flash Tool.
I can format whole flash connecting USB cable in power on exact moment, and SP Flash Tool has been able to format flash.
Now I have problem with Download the stock firmware. I download from differents websites but in all situations SP Flash Tool have an error 50005 (firmware not comtabile) and 10001 (DA or Auth virification failed)
I keep trying to revive the doogee
My S88pro is also in infinity loop. I didn't do nothing. From one day to another it loops. Does anyone has a solution. Need to access a wallet. Can't find my private keys.

The first task that you don't have to do is FORMAT with SP Flash.
Although mobile are in infinete loop you can flash original firnware with SP Flash tool, but you lost everithing.
With SP Flash you can read all flash memory and separate the different partitons, but I try many times unsuccessfully.
What is the type of nand memory you have? Emmc or ufs?
