Redmi K20 Pro Fastboot, No option to go to recovery because i messed big time - General Topics

So this was what happen, i have been trying to format my phone this day to put a rom and i had an issue (that which never happend to me) my phone was always getting an error either on Parse, or Vendor check, i kinda decided to install TWRP on bootloader as i thought i could go around, but figure out i had to download the files, since i didnt want to lose time what i actually did, was flashing the phone again to see if the phone could go further.. but the phone didnt want to pass to that phase.. i was getting impatient.. i disconnected the cable or "how we can say i closed the program multiple time betwen a flash.
I was on 1909. My bootloader was detected everything was detected the phone everything, but since i thought that windows 10 version 1909 might had something with it, i thought "well why not download a recent version" take in mind i have no option, i have no recovery, i tried already to acess it by pressing and hold POWER UP, it returns right away to fastboot, my phone name isnt detected under device manager, nor when i do adb devices, fastboot devices detects it, and i tried already some commands like passing the TWRP to it, but it doesnt overwrite anything, sometimes i get the error"No devices or emulators found" .
Im lost i think i lost my phone, im desperate
Any expert here that can help me with this?
Im gonna try to go back to an early windows 1809, which i used to format this phone a lot to other rom
Meanwhile i need some help on this

lg mytouch c800 bricked?

hi im pretty new here a friend of mine gave me her lg c800 mytouch to try and fix it for her.. not sure what she did she said she rooted the phone and the root was successful but i have a good idea that she doesnt know what she was doing..i will post a pic of the error screen im getting. but it says
E:Cant find misc
E:cant find misc
Finding update package...
E:unknown volume for path [sd:/download/adb_fastboot_and_other_tools.Zip]
E:Cant mount SDCARD:/download/adb_fastboot_and_other_tools.zip
Installation aborted
facory reset failed
restart factory reset..
now im far from a pro at this i know a lil more about computers and Ios devices..but ive rooted a few phones and to me it looks like she unzipped adb fastboot on her phone from her sd card??
ive tried holding F..A..vol down..and power..Nothing..
ive tried volume up .volume down and power still nothing..
BUT if i hold E..vol UP and power it brings me to a white screen that says S/W update
the big problem is the phone wont stay on long enough to do anything on the computer it stays on 3 sec. then reboots to same screen (computer says phone is unplugged) then phone just keeps restarting.
but the phone WILL stay on when i put it on the S/W update screen..but computer wont recognize the phone at all on that screen
ive tried the adb and fastboot commands but the phone wont stay recognized..it will recognize the phone and say thats its in recovery mode but when phone restarts it dont see phone no more..
well thanks ahead of time if anyone has any input or solution
and hopefully all this will make sense to someone lol
i think this pic will work.. if not ill try again
any ideas please?? or am i completely out of luck?

...do you mean that you can successfully communicate with the phone over USB, but you only have 3 seconds? What way is the phone recognized? Is it visible to adb/fastboot?

Yes In Adb device list it shows the phone and then says recovery..but after that I don't have enough time to type any other commands ..the phone is also recognized in "my computer" as removable device then when the phone restarts seconds later it says device unplugged ..and just keeps restarting on its own till I remove the battery...I just read on the forum in a post that Adb will recognize the phone if it's off but I remove the battery and put it back in and plug in USB and phone turns on and keeps restarting won't even let me turn it off!! I'm losing patience with this thing lol
But I don't get why the error mentions fastboot? Not my phone so if it's not fixable I don't really care but I'm just the stuborn type when it comes to fixing electronics ..again thanks ahead of time to anyone that helps cuz I'm completely lost on this one
Have you tried timing it to send a quick "adb reboot recovery"? If you can use fastboot, you can tell it to boot off a new, custom recovery img, without actually flashing it.
i have the same problem

i used an app on the market to remove bloatware. i removed slacker and the app stated that after two reboots that everything would be fine and the app would be gone. after one reboot the phone has the same screen this gentlemans lady friend has. it looks like the app its looking for is no longer zip aligned properly. someone told me to rename a recovery image the error message to trick the bootloader into thinking the missing app is there. hes an app dev so i figured he knows whats what. ive tried everything the gentleman in this post said and more. hell i have two of these phones and rooted the other and made a backup of that phone and dragged the backup to an sd card and rebooted to see if any of the backed up system apks would trigger a successful reboot but to no avail. i have all the drivers i need and adb commands but nothing works because the phone doesnt stay connected to my pc long enough for anything. please reply with some knowledge. ive been scouring the web for at least a month. i was so happy when i came across this. i actually became a member just to post about this erroer (look up diabolus ae in the forum search field. my post is about 3 days old with a better pic of the screen message. i bought a galaxy s II but i want to give the lg to my son. please help or respond:cyclops:

Normally, if you want to flash a custom recovery through fastboot, people will tell you to run 2 commands:
fastboot flash recovery nameofimagefile.img
fastboot reboot recovery
Since you don't have time to execute those 2 commands, you can tell it to just boot from the .img file, without flashing over your current recovery. (This is actually proper form, as you can test if the .img file works properly without damaging your existing recovery.) The way you do that is to 1st copy a recovery .img file to the root of your SD card, then execute the following 1 command:
fastboot boot nameofimagefile.img
Since you only have ~3 seconds, type the command in, and wait for the right instant to hit enter on the keyboard. If the command is successfully sent to the phone, it will reboot into that .img.
See if that works for you. Good luck.

Bricked, stuck in TWRP and adb issues also

Hello there, recently I tried to get TWRP for my LG G2, and I kept trying over and over again to where my phone's booting got stuck in a loop and began making a lot of drives. Luckily, I found http://forum.xda-developers.com/showthread.php?t=2582142 and got to the point where I could get into TWRP. The problem is, now I can't boot up into the normal rom, which I'm guessing has been erased through TWRP and my own stupidity. So I have no roms to flash either, and in addition, my screen is screwed up, and while I can navigate TWRP, I have a very hard time doing it. Also, whenever I plug my phone in to my computer, it just shows up as 'g2' in the device manager, and is an unknown device. I have tried adb sideloading a rom but it always gives me 'error:closed'.
So let's round that up since I kinda rambled there.
Screwed my phone up by trying to get TWRP and it ended up booting in a loop and making a ton of drives.
Was able to fix this and am now able to get into TWRP, but the touch screen is going crazy and I have a hard time navigating TWRP
Whenever I try to use adb with my phone, command prompt says 'error:closed'
The device manager calls my phone 'g2' and thinks it's an unknown device.
I swear, if anyone here can help me get this phone to where it's booting up correctly again, you are incredible.
Thanks!

Hey Pal try -> http://forum.xda-developers.com/showthread.php?t=2663369 but you will wipe everything on your phone but at least you can start with a 100% working G2 D800!
Crap I forgot to mention I can't go into download mode. Sorry about that..

HTC DesIre 320 Bricked, no boot, only recovery...

Hello, I'm about to giving up,
Something happened to the phone and now it won't boot, it barely show the "ANDROID" logo when it restart itself. I can enter to the recovery menu, it doesn't have clockwork recovery nor twrp, just the basic recovery. So far I tried:
wipe data/factory - didn't work.
wipe cache partition - didn't work
apply update from adb: Adb just work with sideload and that's it, for everything else it shows closed. I tried sending the rom with sideload and it fails every time:
* failed to write data 'protocol fault (couldn't read status): Invalid argument' *
So I took my sdcard and copied the room there, so I tried
apply update from sdcard, it starts and in no time it says:
Installation aborted (APPLY_EXT).
I'm very frustrated right now, nothing works, it seems that the manufacturer did great effort on being the only one who can recover this phone, who appears to be from China, the MTK6582.
Fastboot? it doesn't show the device, it would be my last hope but no, since there is no adb, I cannot call fastboot, and the apply update from adb only work with sideload (yeah, f**k me).
The best course of action would be to throw it to the trash?
Thanks!
Hey, I'm in a similar position to you. However, I went about it with a slightly different route. The chip used in this phone is the MediaTek 6582 (I think?). I downloaded some tools from a thread on here that includes the 320 rom and the necessary software for flashing. I've flashed MediaTek devices before, the Huawei Ascend G610 and G700, both successfully. This one is giving me headaches, the damn device keeps disconnecting. HOWEVER, if you're lucky and you don't have the same problem with disconnecting hardware, you should be able to flash a new rom via the software. It'll take a while though. Also, I don't know what'll happen to your IMEI afterwards, so that's another possible headache (both the G610 and the G700 lost their IMEI info, but I'd taken steps to back them up beforehand so I could just restore them; here, there's no option to backup).
Here's the thread: http://forum.xda-developers.com/android/general/htc-mtk-cpu-flash-files-flashtool-t3114271
Let me know if you need help. I'm screwed in that the damn phone keeps disconnecting. Similar to you, no fastboot either. Plus, no RUU for this HTC. Hell, the internet barely knows this flipping phone.
Cheers, and good luck.

Ditto!!!
Hey guys I am having the exact same issue, luckily for me it is my Mrs who done her phone in and not mine . She has the HTC Desire 320, I believe she tried to root it on her own without even asking for advice, I think she used the app Kingo Root, she said she went to remove the root but when she uninstalled the app it didn't remove it. (LOL I told her well perhaps that's because there will be some way of removing it, aside from just uninstalling the app), anyway she proceeded not to care and carried on using her phone as normal for maybe a week or two at most, then about midnight one night, came down and said to me,
"my phone had an update and on restarting I just get a dead android, if you press the power button you get some options so I clicked erase"

I was like nice so basically you F***ed it!!!!, and for about 2 weeks now I have been endlessly reading post after post, forum after forum, trying rom after rom, RUU, all kinds of things.
Here is the situation, the phone will boot as far as the HTC logo, it will get stuck in a short loop and reset itself 4/5 times repeating the HTC logo, eventually it will end up at the dead android pic (the android on his back with the red exclaimation mark triangle) with the words 'no command'. From here I can press the power button once to get a list/menu of items (What I assume to be the recovery menu). I can backup data, I can restore the backed up data (both of which do nothing as I guess there is nothing really to back up), There is an option to restore from sd card (which I have tried numerous roms and to no avail have any been successful), I can erase the cache and I can also erase everything and recover, the erase side works fine, I did notice in each of these menu that if you press volume up to activate them and then press the power button once, then the writing dissapears and the android proceeds to have his moving atom type thing in his belly, saying 'erasing..', however even with them completed successfully, it still does not restore.
NOTE!!! If you choose the erase and restore method, once activated with volume up, press the power button to get the spinning atom and erasing... message, when this finishes the phone will reboot, it goes to the htc logo, resets itself, goes to the logo again and then just stays at a black screen (almost like a frozen state, I left it for quite some time and it never changed).
I should also note, which I didn't to begin with, but no matter how long I hold the volume down and power button, there is no such hboot/fast boot menu at all, if you hold the volume down and power button even after it displays the htc logo, the phone just proceeds to endlessly reset and loop through the same process forever.
The only thing I can seem to access with little success, is the ADB CMD prompt through the Android SDK,
Code:
adb devices
will indeed return the device (a set of numbers with the word sideload beside it)
Code:
adb usb
Apart from the odd fluke, this has seemed to fail everytime with either an error about a protocol or an error stating 'closed'
Code:
adb sideload "ROM_FILENAME.ZIP OR .IMG
Occasionally this will throw the protocol error, but generally succeeds and displays the 100% most of the time, however the phone doesn't even try, it just almost instantaniously returns the error message :
Code:
[B][I]Installation Aborted (APPLY_ADB_SIDELOAD)[/I][/B]
NOTE!!! That the android lays on his back with this error, but it only says error below not no command.
I am pretty sure that I already came across a solution very similar to the one you posted above, and I just couldn't get it to recognise the phone, the only way the RUU would work, was by completely removing the battery and plugging in the usb, however without the battery in the phone, it just constantly beeps via usb, so I guess it turns on, then off, then on, then off, forever!!! So the RUU fails everytime, if I leave the battery in and try, the RUU program does nothing whatsoever! So I am at a complete loss with it now.
Cheers

Any luck with unbriking the HTC?
Maybe this is the solution, good luck.

I think that you no tell true because I tried this method with volume keys and nothing. Flash tool still show error. Its impossible to write android without battery. I think really put your phone to rubbish or sell as lcd+digitizer parts I think just we must waiting for new custom rom flashable via stock recovery. 320 is still new model and developers no moke any custom rom. So maybe only HTC service may help, only in HTC Factory peoples know how install android and bootloader on hard bricked device.

Oneplus One bootloop with Linux

Apologies if something similar has already been posted on here already. I have had a look, but can't seem to find anything.
I was trying to root my oneplus one this evening, and was following a very useful link here....
https://forums.oneplus.net/threads/like-a-boss-how-to-root-your-oneplus-one.58493/
....and got to the bit that says "sudo fastboot oem unlock" - waited a minute, and the phone rebooted showing the android and 1+ logo. But before anything else happens it turns itself off, then back on again. And continues to do this indefinitely. I can get it into fastboot mode, but not recovery. When it is in fastboot mode the pc doesn't recognise it. Something obviously isn't right, but I'm not sure what. I'm guessing something is possibly corrupt.
What I think I need to do is firstly, get the pc to recognise the phone somehow. Secondly, install a recovery on to it and thirdly, flash a rom. I've been scratching my head all night trying to work out how to get the phone recognised, and Googling like a teenager who's just discovered porn is available on the Internet.
Is there anybody out there who is familiar with Linux who can possibly walk me through what I need to get my phone working again?
Thanks for taking the time to read this, and for any help that may be offered.

I made a goof rooting my phone, please help

So, I followed all the basic instructions of getting ADB, downloading and flashing twrp, and my goal was solely to root my phone so I went ahead and got SuperSU as well and installed it through twrp. Everything went fine until I went to reboot my phone and it wouldn't work, it would only boot into twrp no matter what I did. In a moment of foolishness, I decided to go to the reset section of twerp, and switched to partition A (it was on partition B, where everything had been installed). Now my phone only has a black screen, and no amount of trying to soft reset or anything is turning it on. The only indication I have that my phone is doing anything, is that when I plug it in to my pc I can hear the connection sound. I can't access any files on the phone, and ADB doesn't recognize that the phone is plugged in. It's a Moto g7 power phone, and I used the latest versions of the programs. Also, I did do something of a ****ty backup before I started the process, but since my phone wasn't rooted I don't know how much that'll help me. All the stuff I find online says to just install a stock rom or whatever; but I can't even access my phone to do that. Is there ANYTHING I can do or am I ****ed?
Thanks so much for any and all help
