problème boot loop and root fail - General Questions and Answers

URGENT!!!! I did everything well except that I used the wrong img boot compared to my model, suddenly everything worked well but my one plus 8 pro no longer has the wifi working. so i will want a quick fix, if anyone can help me i would like to go back and have everything as before, new as factory.
I tried to install a stock one plus 8 pro global rom but the problem is that having wanted to unroot my smartphone I had to do a bad manipulation and my phone is in an infernal reboot loop. In the meantime, I manage to reach the bios with the recovery mode, the fastboot etc ... but the smartphone no longer has the usb debugging activated. I need to find a solution

[Completed] [Q] touch not working, cannot flash img .... bricked tablet?

hello everybody...
i have a (spanish jazztel) i-joy 10" tablet, cortex a7 quad core.
i made a mess with titanium backup and when tried to recover factory settings i realized that i had screwed the recovery data.
system would boot up, tablet would work but with many errors and "stopped working" pop ups.
i looked for a stock rom just to find out there is NONE in the WHOLE INTERNET!!!
then, googling here and there i read about some compatible roms, from allwinner, kalley and other chinese brands.
i downloaded all img files i could find, i flashed them correctly with phoenix usb pro, one after another.
first two worked well except for the cameras, that wouldnt work.
then i tried ICOU10GT firmware, flashed correctly...but touch DOES NOT work, i cannot go any further from welcome screen since the touch screen is not recognized.
i am 100% sure is not a hardware problem, all physical buttons work, screen works but not touch.
since i cannot reach the "enable usb debug mode" option i cannot flash any other img.
when entering recovery mode, if i choose update from adb the tablet is not fully recognized by windows (driver says device cannot start).
i´ve tried sd burning with phoenixcard but doesnt work either, tablet doesnt boot up from external sd card.
is there any way to recover this working-but-bricked tablet?
please help!!!
------------------
if there is not....is there a 100% safe and sure way to commit a "perfect murder" with the tablet to send it to post-service and being able to claim "it just stopped working" and them not being able to see i flashed it? i guess you know what i mean.

Chuwi vi8 android boot loop

hello
so last time i wanted to install that "touch fix" for my Chuwi vi8, after a reboot my tablet wasn't able to boot anymore, it just won't stop to reboot, i can still boot to Windows with lock+up volume + home button, i can also go in the stock recovery mode, yes i already tried factory reset and it didn't worked, how can i fix it ?
i can also get clockwork mode but i just have error closed... i installed all the drivers i was able to found but no one fixed the "error closed" when using sideload, also i don't know WHERE IS THE STOCK ROM...
I have this www needrom com download chuwi-vi8-dual-os
"file is too big" so i format in NTFS but then the tablet won't recognize it, and seems like it's the WINDOWS ROM i don't need the WINDOWS ROM I JUST NEED THE STOCK ANDROID ROM
i've been trying to fix this since MONTHS, tried yesterday, it took my whole day today and yesterday STILL NOTHING.
i reposted this here beacause i think i wasn't in the good category sorry i'm new
IF someone can REALLY HELP ME, do i'll have to PAY SOMEONE to fix my tablet ??? Like really, i already posted this in december no one answered me...
Ok, so it can't be fixed, great ! Thanks ! XDA brokes my device and won't repair it....

[Completed] is this a soft brick or a hard brick? can i fix my phone?

I've been trying to root my phone for the last few days, everything just seems to be going badly.
I was finally able to unlock the bootloader, and i wasn't able to flash TWRP
after trying to get it to work and faffing around in recovery. I some how have got my phone in an endless loop. But not just an endless loop, but after the phone logo comes up, my phone's screen goes all glitchy and crazy with loads of colour. I can go into fastboot mode all ok, but now i can't access recovery mode anymore it's the same as normal mode.
I have no idea what's going on
i can't flash anything, when i do i get the message USB Transferring ... USB Transmission OK
Hi !
This looks like a soft brick but can you tell us more about your device ( model , software ) ?
Thank you

Hi !
Some devices just can`t be unlocked without a prover support from the manufacturer
You can search for more on Google and wait for development , your case is far from unique
I see that you have alredy posted same issue here

[Completed] Doogee X5 Pro Bricked

Ok, i have a doogee x5 pro phone and i tried to root it by flashing twrp recovery using sp flash tools. While flashing i got the error "PMT Changed for the rom it must be download". So i did a small research on internet and i found out that i needed to format everything except bootloader. This succeded. So after that i tried to install the firmware with this succeding to. Unfortunately the time i tried to turn phone on it was dead. SP Flash Tools wont detect it anymore. Please help me cause the phone is not mine and its brand new! I can rate my self as moderate android user. :crying:
i think i have a bigger problem... I downloaded a stock rom for doogee max pro(cause i just realised it wasnt just pro it was max pro) and it didnt seem to be recognised again. Any help would be appreciated. I constantly keep trying to raise it from the deads. Thanks!

On mtk devices a preloader is independently installed, it should be almost impossible to destroy, I owned a x5 pro and had best success to flash it with sp flash by taking out the battery, press flash button and plug it in...
The second huge issue I see is when you used the specific flash tool format option you very, very likely killed the nvram partition which contained the imei, so you'll have to fix this too by generating a new one and using mtk engineer mode which is well described and to find on Google..
But let's go step by step. Check without battery, or if it's a non replaceable you'll need find the reset button..
i have tried before without battery and i tried just now but nothing. Its very weird it was detected before and now no in same and another machine. I am pretty confused and stressed. Hope i didnt do any physical damage.. :crying:. THANKS!
starting to get pretty stressed omg! and is there a difference between MT6737M and MT6737?
i came to the point im starting to lose my mind... tried everything i could, i have 5 days left to repair this phone and i dont wanna pay 85 euros for this. SP Flash Tools wont detect the phone. Tried almost 5 different scatter files,2 different PCs and different mtk drivers. Im losing my mind already
UPDATE: I almost fixed it! I had flashed wrong preloader so phone wasn't recognized by SP Flash Tool. I fixed preloaded with a little trick from here: link. After that i flashed stock rom downloaded from doogee.cc but phone will not boot resulting in a total black screen. When i hot Power + Vol Up it takes me to another screen:
Select Boot Mode:
Recovery
Bootloader
Normal
Doesn't matter which boot mode i choose i just get a total black screen which means i get nothing. Idk what is happening! Any further help would be appreciated! I constantly try to bring it back working with little success and small improvements.
Last UPDATE: FIXED my phone had no juice left inside so couldnt complete boot proccess. Now its all good running Btw someone must pin this META trick link i send on my previous post cause im sure more people out there have preloader issues!!! Thank you everyone!!

Bricked p40 pro after downgrade...

Hello
I have a soft bricked (?) p40 pro , after downgrading to a wrong firmware version, the phone booted up normally inside android and was working for a while.
But after trying to OTA update it, the phone went into a bootloop. Failed at installation and restarted.
I can access now only eRecovery and Fastboot modes.
I can't get it recornized by a PC with usb, i dont know if i do something wrong.
eRecovery also doesn't work. It managed to find once a package, downloaded it and while installing the deviced rebooted and went into bootloop again.
Now its stuck to unable to find package info.
Haven't try dload from usb-tongle, because i dont have any usb tongle / adapter. Im willing to get one to try out, if i can flash anything from there.
I went to a service shop, they said they tried with test point and they still didn't find a work around it. Maybe they lack experience on this device.
If someone can help me please, im very desperate
I had the phone only for 4 hours
Thanks
Alex
