Unable to boot my Realme 7 into anything. Just boot looping.

Unable to boot my Realme 7 into anything. Just boot looping. - Realme 7 Questions & Answers

Hello,
This problem has been going on for a while, and I just decided to try and tackle it again.
My phone is currently bootlooping.
Realme logo - "Orange state" your device has been unlocked and can't be trusted, it will reboot in 5 seconds.
It then reboots...Nothing.
I know what I need to do, but I can't get Windows to recognize the device. I've tried holding volume + and - at various times when the screen is black. I've tried volume - and power, I've tried vol + and power...Nothing works.
I can't even get it to turn off...No idea how to get Windows to recognize my device - Currently trying to get the Libusb filter wizard to see the phone to installed the drivers...I've also used the mtk thing too - But it never finds my device.
No idea what's going on here...
Searching for some advice in case I'm missing something simple...

If you cant boot into anything you need to unbrick your device.
Follow that guide, helped me many times...i already needed to unbrick that damn thing for about 20 times.
Keep that files on your pc for future needs, its big.

Great, thank you for the tutorial. That one I haven't seen yet.
However, the BIG problem that I have is that I can't connect it to my PC. LIBUSB doesn't see the device, Windows doesn't see the device. and any software doesn't see the device.
My issue comes with holding the buttons to have my phone boot into the specific mode required - I can't get it to boot into anything other than a loop...

thanks for reply
my device is china MT6572 with android 4.2.2
I have use a very very very superb tool named "MtkDroidTools v2.48" and bricked my newly purchage tablet.
1. I click on root and happy thing is that tablet got rooted. wow
2. I have created backup from this tool and after few minutes, many *.img backup files are created on my pc and my tab's sdcard. wow again
3. After restarting the tab it restarting again & again and not booting. really a "heart attacking wow".
I have tried following steps
1. In default "android stock recovery 3e" trying to restore backup files and got message "installation aborted" everytime. same message from using "adb sideload command"
2. creating a scatter file from this tool and load backup in "SP_Flash_Tool_v5.1343.01" tool. but no any tool connect my tab. it says no device.
3. only "adb sideload" from stock recovery has the way to connect to the pc. but I don't know which kind of files are used at there??
During the backup process a log file created by MtkDroidTools has attached for details information.
then plz tell me. what I do for get again a "relaxed wow"??

Load scatter file and back up files in SP Flash tool. Power your tablet off, hit download button in SP Flash tool then connect tab to pc.
If you have the preloader driver installed SP flash tool should connect and start flashing firmware to phone. Do you hear the connecting sound when you connect powered off tablet to pc? If not, you may need to press and hold Vol Down, Vol up, or menu button while connecting tab to pc.
Hope this helps and good luck!

Ok, no need to hit a combo of buttons, only 1 button you need to press while connecting tab to PC. Please retry following the directions from my last post again
Yes, preloader will only show for a few seconds in device manager before it turns off. Preloader is only for reflashing firmware. When it enables itself, it is looking for the SP FT (or other firmware flashing programs) to be there to catch it, if not preloader shuts itself off.. Your download of SP Flash Tool should have included the needed preloader drivers. Then you load files in SP FT and hit download button then connect tab to PC.

Thank you very very very very much. Finally I have got a wow.
After many efforts, I resolved the tablet booting issue. It is possible due to only your valuable suggestion.
steps are here:
1. connect tab to pc & installing preloader usb drivers.
2. getting VID & PID of tablet usb connection.
3. modifying "SP FT settings files" with new values of my tab.
4. creating a scatter file from droid tool & load in SP FT.
5. Flashing backup to the tab successfully.
You are such a genius. I have been wasted a lot of time since a week for getting the right answer. During this period I had connected to many android experts at many sites. but no satisfaction answer.
And u are really amazing. You have got the real problem in only three conversation. really great.
Well I m a windows expert. If u feel any technical problem regarding servers or windows, ask me, I will try my best.
I am launching a website soon named "GeniusPepoleofWorld.com". Many technical experts & genius people will listed there in different categories like Android experts, Windows experts, Linux Experts, Robotics Experts, Electronics xtra xtra. I want to add you at top there in Android Expert list. Now site is under constructions. I want to know your name & personal mail-id like gmail etc. When I will finish my site, I will inform you.
One more thing I want to know that "what is the use of stock recovery & adb sideload, which files types are used with it?"
Plz plz reply this with your name and mail-id.

I am happy to hear it worked for you. Nice job Raj! I am just passing on the knowledge I learned here on XDA (Thank @rua1 he made MTK DroidTools and without that tool alot of folks with MTK devices wouldn't have root, stock firmware back up files, or working recovery
Anyhow, as for your last 2 questions. Stock recovery is used for flashing officially signed update files from your device manufacturer (If they were to make an update that is lol) This is how all android devices are able to accept ota updates, they download the file to phone/tablet then reboot into recovery and then it flashes the downloaded file to the device.
Adb sideload allows you to connect the device to a PC and then upload a firmware file to device to be flashed via recovery instead of downloading it directly to the phone. This is useful if you had an officially signed stock firmware file for your device stored on your pc. Some custom recoveries also allow you to use adb sideload but since you have stock recovery you would be restricted to using only officially signed files.
Say for instance you were not able to get your device to boot properly, you would just need to boot tablet into recovery mode and then choose adb sideload. At this point you would connect tab to PC and then put your firmware file in the same folder you have adb.exe in. (Let's call the firmware file "firmware.zip" in this example) Then open command prompt in same folder that adb.exe is in and type "adb sideload firmware.zip" this would push the firmware.zip file to the device then flash it for you.
Since you were able to use MTK Droidtools to get root then make a back up, you should be able to also use it to make a custom recovery for your device too. When you made the back up, it will usually make 2 back ups, one on your pc that you use SP FT to flash files and restore your device then it also makes a back up on your devices sd card that is flashed through custom recovery to restore your device. This would make restoring your device pretty easy if you need to do so again and it will also allow you to restore without needing a PC to do it.
Hope this helps!

device not booting
kbrahma said:
I've got the exact same problem with my phone... My phone, Celkon A15 (Indian brand) also has the same chipset number and while trying to root using MTKdroids tool, I have managed to get it in the boot looping stage.
I'm just curious on how you managed to get the pre-loader installed for this? I CAN NOT get the SP Flash tools to detect my phone for the life of me. Also, when I load my scatter file, it has the "PRELOADER" section in RED... and when I try to upload the preloader.bin from my backup files, it says... "Load file "*path name*" fail!"
I am still struggling to understand how the SP Flash tool works and if it would be able to get my phone alive again (well it did help you out, so I am bit optimistic).
Please HELP!

Hi
1. First you have connect your device to pc.
2. you have to open the device manager and keep your eyes on a new hardware found at device manager, when you start up your device.
3. Preloader will only show for a few seconds in device manager before it turns off.
3. install preloader drivers.
4. open SP Flash tool and load scatter file and set path for your backup files.
5. Click download button and reboot your device.
6. Software will catch your device and finally backup will be restored to your device.

[Guide] How to unbrick redmi 9C by flashing with SP Tools without Auth file(Tested Working)

This is a last ditch effort to restore your phone to working order. This should only be used if your phone DOES NOT BOOT AT ALL or if you are unable to boot into FASTBOOT.
If you can boot into Fastboot mode then I would encourage you to flash using Mi Flash tool.

Tested! Howto Unbrick Redmi 9C (angelica) without using auth account
This blog has move and will not be update again.For new update please open ▶▶
langithitam.wordpress.com
First you need to extract the MTK bypass tool which is crucial as it will allow us to flash without requiring Auth file. NOTE: you need to disable antivirus or it will delete file.
Your PHONE NEEDS TO BE OFF! There is no need to unplug battery from the phone, I tested it myself and as long as the phone is OFF it'll still work. If your phone cannot power down due to bootloop, then you must remove backcover and unplug battery or just wait till battery runs out.
Once you have started the MTK bypass tool, choose MTK6765 from option that says auto and this is only for Redmi 9C. Now press on the bypass button a ad it will wait for you to connect your phone via USB. DO NOT CONNECT YOUR PHONE PRIOR TO THIS. Hold only the VOLUME UP button when connecting the USB cable to your phone and ensure the phone is OFF. ONCE you connect the phone, it will immediately respond and show a log saying its completed (SEE SCREENSHOT BELOW).
Once this step is completed leave your phone connected as you will soon start the flashing process. Open up SP FLASH TOOLS and run as admin. You will need to load the scatter file which is included in the Fastboot ROM under images folder. Once you have the scatter file loaded, SP tools will proceed to load all image files which will be used to flash phone so be patient.
Ensure that DOWNLOAD ONLY option is chosen as format and download option will format your IMEI also. Once all files have been loaded then just press the DOOWNLOAD button and wait to complete. Once done you can power ON the phone and it should boot.

Very good guide.
Thank you very much

No problem hope it'll help a few guys out there sure helped me a lot

Cool glad I could help

I'm using a Redmi 9c I tried to unlock it but failed in the process. Later I get absolutely no response from the phone, I cant open fast boot or recovery. I tried connecting it to the pc but it shows the same exact problem you are facing. I tried all USB ports and switched cables back and forth but no success. I tried pressing volume up, down and all sorts of combinations, still no success. Any fix for this?

Follow the guide step by step, it should work and if doesn't then you should try disconnecting the battery

great guide on fixing a hard brick.

My compliments and thank you very much indeed to you for writing this very good and detailed guide. My Redmi 9c bootlooped after trying to install Lineage OS, of course no way to go to fastboot mode anymore (I'm a rather experienced custom ROM installer though). Although I asked for help in a separate thread, I got no answer for a couple of months now until I found this thread. I never gave up my Redmi 9C so I now followed you instructions and with success!! I will refer people to your thread of course. There is no doubt many can save their phone by reading you instructions.

I can do this for a Redmi 9a?
Using the same download agent

Hello, i did it but i did the mistake to do a FORMAT AND DOWNLOAD.
No my phone juste diplsay the Redmi logo a few second then power off.
I'm still able to go on the Sp Flash Tools and flash again. Anyone could help me please ?

hello sir so i recently hard bricked my redmi 9c nfc by installing older MIUI version that it came with. It was just black screen all the time and nothing. Tried this guide, mtk bypass tool worked but on sp flash tools i am greeted with this message.

Everything is acting like expected according to the video, but wheb I have used the mediatek bypass tool with green OK and stuff and when i start to press download on the smart phone flash tool, it just stucks at 0. Nothing happens, except that everything is greyed out and is trying to load it. If i boot my phone myself with the brom it says hint:add a authentication file or ask for help. I cant manage to finish it.
The error in Mediatek bypass tool about handshaking error is probably because i did it several times, because i didnt manage to load smartphone flash tool as attached below
This is my last hope to recover my brandew phone. Thanks for the good tutorial, but it didt work out. If someone could save me then I would be grateful

Mi a3 hard brick, Screen Black, Haven't opened the backside of my phone yet.

Hi, I beg your help. Well what happened is,
I was on CORVUS OS, then I thought of rolling back to stock rom. So after flashing "laurel_sprout_global_images_V12.0.21.0.RFQMIXM_11.0" using Mi Flash tool (clean and unlock), My phone said to me "This device has been destroyed". So I thought I might have flashed a wrong version. So I again flashed "Xiaomi_Mi_A3_V10.3.4.0.PFQMIXM_20190815.0000.00_Global_9.0_XFT" using Mi flash tool. But this time, android one logo showed up and did'nt proceed. Luckily I could access to fastboot mode. But after doing this flashing few more times, My phone blacked out completely. Things I have done so far:
1. Tried flashing again using Mi flash tool. The device manager says that the "QDloader 9008" is connected properly, but the flash tool is saying "cannot receive hello packet" and eventually fails the proccess.
2. Tried volume button and plugin combination. Nothing happened.
3. Download QFIL software. But it's not detecting any device.
4. Tried switching USB port
Please save me. I am going through a disaster. and it's my primary driver T_T

try to disconnect the battery, and plug usb

Try flashing using Paltform-Tools instead of Mi Flash Tool. See https://forum.xda-developers.com/t/slot-a-is-destroyed.4399965/ for links to instructions.

Do not take the back off your phone. Seriously, shell out the ten bucks for the deep flash cable. You need to get to EDL. Here are a couple of methods, depending on what you want:
Repackaged A11 stock here: https://c.mi.com/thread-3527044-1-0.html
CC9e Conversion here: https://forum.xda-developers.com/t/miui-12-port-10-miui-12-for-mi-a3-stable-weekly-rom.4016457/
Note: If you want to use QFIL, make sure you're using the latest version with QPST. Save yourself the time and install it system wide. https://qpsttool.com/qpst-tool-v2-7-104

Question Help! My Oneplus Nord N200 5G cellphone is bricked.

I am currently trying to install LineageOS on my phone. I personally have never unlocked or reinstalled a new operating system on my phone. I looked on some XDA forums for some guides and i found one and followed the steps. I unlocked my phone and I installed a custom TWRP because I was trying to downgrade the phone back to android 11. Once i was done flashing the file to the phone and rebooted it doesn't boot anymore and only gives me a booting screen for a few seconds after I hold down the power and volume up button for a few seconds nothing else works. I have use the MSM tool and put my phone into EDL mode and it detected the phone with a black screen. Every time I use the tool it works till about 18% then it gives me a Sahara communication failed error and then my phone gets out of EDL mode.. I installed all the drivers needed on my PC and used multiple USB 2.0 slots but it still fails. Any help would be appreciated.

There are warnings in the TWRP thread for the N200 that it is broken and should not be flashed.
I have written an easy to follow guide here to downgrade to A11 with Fastboot Enhance.
Unfortunately, now that you have used MSMTool on the phone, it is now bootloader LOCKED. This tool should be the last resort only if you are already hard bricked. You could have gotten the phone into fastboot if either boot.img was still intact and re-flashed the rom with a still unlocked bootloader. The phone will change slots after so many failed boots.
Now that your boot loader is locked, the only tool that can modify the phone is MSMTool. If you can get into Recovery, do delete user data and try again.
Otherwise, you will need to get an RMA and send phone back to OP.

Sorry I should have written more details but I currently have a hard bricked device. It will not boot and It failed to boot like 20 times. It will not enter fastboot or even get past the logo when you first turn it on. I did use MSM tool after it wasn't letting me into fastboot. Thanks for the help and I will send it back.

It will not enter fastboot or even get past the logo when you first turn it on. I did use MSM tool after it wasn't letting me into fastboot. Thanks for the help and I will send it back.

Can't boot to fastbootd mode

Hi, I am using a oneplus 7t pro mclaren edition. I have soft-bricked the device. I tried to change the filesystem in twrp to f2fs when i was in stock rom (I know it was a stupid mistake). Now the boot and recovery partitions are destroyed. I can boot to actual fastboot mode. Tried to use payload dumper but whenever it tries to boot fastbootd it says
fastboot: error: Failed to boot into userspace fastboot; one or more components might be unbootable.
Tried erase everything I got the following error using "fastboot -w"
Erasing 'userdata' OKAY [ 0.229s]
/home/abhijith/Documents/op7t/output/make_f2fs failed with status 1
fastboot: error: Cannot generate image for userdata
I have heard of MSM unbrick tool but as far as i know it only works in windows , before installing VM with windows , I want to know if there is any other way i can recover my device. I have a11 fastboot rom and a12 stock rom. Please help

I have exactly the same problem, same errors etc. if I find any solution I'll post it here. Can't use my phone until then I guess. It all happened after my phone was bricked after trying to install TWRP (previously used LineageOS Recovery).
I followed this guide which resulted in the same errors as for you: https://forum.xda-developers.com/t/...ock-fastboot-roms-for-oneplus-7t-pro.3991189/

Okay, I managed to unbrick my phone, but you won't like the (probably only) solution:
- You NEED Windows (7-10) for this, as the tools are only available on this platform, sadly
- There is this one Indian Guy that will save you:
- Includes how to install all drivers and how to get your phone into COM Mode
- This uses the MSM tool. For 1+ 7T Pro, get it here: https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4002909/
- This is going to STOCK RESET you phone 100%, meaning that your bootloader will be locked etc.
- If you get into any Chinese menu after the phone reboots, you can use Google Lens for translation
I can't believe this worked because it just feels so hacky, but trust me, it's a good last resort as you can always put your phone into COM Mode, regardless of how hard you messed up the system [citation needed].

Follow the video. When all drivers are installed and you hold both volume buttons while the device is off, it will show up as a COM/serial device for a few seconds before booting.
Important: Only connect the cable while already pressing the buttons or it won't work.

I was able to get to edl mode and msm tool was detecting but now i am facing sahara communication error i dont have official cable so maybe that might be the reason will try that also

@Colin_T Thanks for the help. I was able to install stock rom to my oneplus 7t pro. I really want to install pixel experience, in the instructions it is saying flash oos 12 firmware. But in the official website i am only seeing 11. What to do?
