[Q] how to flash without fastboot? Brick phone first? - Android Q&A, Help & Troubleshooting

Hi,
my phone hard resets every boot and the command:
adb reboot bootloader
only restarts the phone , which then runs recovery, resets and then boots android.
The only thing I can think of is to use a root file manager to wipe everything in sight (and with it whatever it continually sending the phone into recovery) and then hopefully it will be able to enter fastboot.
I'm an IT pro but linux and phones are out of my depth. Please help.

where is the recovery files located... can I delete them and hopefully brick the phone to be able to get it in fastboot?

[Q] unable to get to bootloader or fastboot

hi,
i am trying to install CWM recovery on my phone (eventually want to install custon rom)
The phone is a huawei inspira, there no development for this phone. No info anywhere..
Withins the phones readme, it says its a U8666E, so going by the little development for that phone i am trying to install CWM.
I was able to root the phone, and i think i unlocked hte boot loader too (using the unlockbootloader.zip).
I have tried really hard, but am not able to install CWM as the phone is not coming in bootloader mode.
if i press hte power + vol down button phone is stuck in huawei logo (as it should) but PC does not detect it.
If i reboot bootloader (from adb) it just does a normal reboot.
i have tried a whole lot of things (new pc / usb port / cables / drivers etc etc). I every tried putting recovery on sdcard and flashing from terminal emulator of phone with no luck..
i am at a point where i am ready to flash the rom directly.. (risky i know).. but looks like everythong i want to do required me to go to bootloader mode.
I am not begening to think the carrier of my phone (tracphone) has locked the phone so i cant get into bootloader mode.
an any of you experts help me with my problem?
1) how to verify if the bootloader is unlocked?
2) can i flash CWM OR even a custom ROM with out getting into bootloader mode?
3) i have done a nandroid backup of the phone and kept a copy on external SD as well as PC< how do i restore the backup (if required) without CWM?

How to install a rom only by recovery mode??

Hi, first of all i want to say that i'm new here and i am not sure i'm posting in the right place, if not i'm sorry.
I was trying to fix a problem with my camera app in my Idol X+ (s960), i installed a new one and reboot. The problem is that my phone bocked at the boot image and didn't want to reboot normally. I got into the recovery mode pressing the key buttons. I now want to reset to swipe to factory reset but nothing is working, i cant even install a new rom because there's none in my phone memory (it doesnt allow sd cards). is there a way to tranfere files to my phone without turning it on? because it is impossible i only can access recovery mode...
Thank you very much
Can you access fastboot mode or does your recovery allow for an ADB sideload command?
Sent from my Nexus 4, want to know my current project? Check http://team-fun.eu
I'm sorry, I'm a real noob but can you explain what is fastboot mode and how can I know about the "ADB sideload command"?
I want to say thnk you for your reply!:laugh:
I found out my recovery allows ADB Sideload and when I choose Bootloader the screen goes black with written at the botttom fastboot. Is it what you were talking about? Nothing happens then ...
the only thing u need to do is,, to flash your phone using spflash tools,,

[Q] [HELP] Unable to enter recovery mode and bootlooping

Hi, recently I've tried to install a custom recovery. In the end, I think I've corrupted my recovery img and now my phone just keep rebooting.
But I can boot my phone normally if i use "fastboot continue" in adb shell. But no matter what recoveries I've tried to flash, it just won't solve the bootlooping problem. I've also tried to use flashtool to download back the recovery. But it just keep disconnecting due to the bootloop. Can anyone please help me ?
I'm a user of Huawei Honor 3x G750-U10.

Doogee F7 stuck in bootloop after root attempt

Hi,
I'm new here, so please excuse me if I am posting in the wrong category.
So I tried to root my Doogee F7 (not the pro version) using fastboot and TWRP, and it resulted in a sort of bootloop where it says:
Code:
Orange State
Your device has been unlocked and can't be trusted
Your device will boot in 5 seconds
And then it restarts and gives the same message again. This loop has been going on for some time and I can't stop it because the phone has a non-removable battery and I have tried every possible combination of buttons (i.e. Power + Volume Down + Volume Up).
The process I used in my attempt to root was as following:
1. I used
Code:
adb reboot bootloader
to go into fastboot. (I already set up everything like USB debugging and OEM unlocking in the developer options)
2. I then used
Code:
fastboot oem unlock
and pressed Volume Up to unlock the bootloader. All was successful.
3. I then tried to flash TWRP to recovery and I believe this is where everything went wrong. I flashed it using
Code:
fastboot flash recovery recovery.img
and it was successful, according to the command prompt:
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flash recovery "C:\Users\momen\Downloads\recovery (1).img"
target reported max download size of 134217728 bytes
sending 'recovery' (12832 KB)...
OKAY [ 0.562s]
writing 'recovery'...
OKAY [ 0.213s]
finished. total time: 0.779s
4. After it finished I used
Code:
fastboot reboot
to reboot the phone and that's when it got stuck.
At the moment I am just letting my battery run out, as I have no other way of turning off the phone, and neither adb nor fastboot is working.
I don't really know if my device was even supported, but I followed the instructions on various websites stating that I should first unlock my bootloader, then flash TWRP, then flash superSU onto it, and my phone would be rooted. I used the latest TWRP image, and I think that was where I went wrong. Is there anything I can do to get my phone to work again?
Hey! i´m sorry for your phone, can you tell me any updates, is it fixed now? what happened? i am about to do the same process to root my Doogee F7 and i´m very worried that my phone gets bricked, so please, i need your recommendations.
I hope everything is alright with your phone.

Ah yes, sorry for not updating. I managed to connect my phone to my PC again using the flash tool and then I could flash the original ROM back onto it. I found the ROM by Googling for a bit tho I dont have a link. Be aware that if you do this, it basically factory resets your phone, locking your bootloader again and all. If you do manage to root your phone please contact me as I still have not managed to do so.
Edit: This process of flashing back your ROM always works as long as your phone powers on, so don't worry too much about bricking your phone. I think I've bricked my phone over 20 times trying to root it, and it worked every single time.
Hello there. I suggest that you use "fastboot boot recovery.img" than using "fastboot flash" if you are not sure if the custom recovery works (or if you just want to test/try it). In this way, you'll just boot the custom recovery temporarily (and your stock recovery is still in tacked).
For rooting your device, first you'll need a working custom recovery for your device (you used TWRP, very first if it works or compatible with your device).

Hi.How you actually managed to connect your phone to PC using flash tool if you were in a bootloop and had no access to fastboot mode or recovery?

Im interested too in your process to flash TWRP again, as i am in the same boot loop than you with a Doogee S60. I´ve waited till the battery ended, but now flash tool doesn´t recognize my phone. If i charge the battery, i get a boot loop again..

Uninstalled OS and only TWRP left? Help please!

[At first, I have a Huawei p9 Lite] I recently was stuck in reboot mode, my phone would not boot up anymore and just keep rebooting so I went into twrp and did a factory reset without having a backup because I did not have any important files on my mobile. I then still could not boot up so I accidently wiped the whole cache and deleted my OS, so now my phone won't even boot anymore and it's stuck in the "Your device has been unlocked and can't be trusted" screen. How do I make my phone work again? I don't know anything about how to download stuff on my phone when I only have twrp left so I can install it with twrp and then boot again.
EDIT adb push doesn't work either and I can't wipe because it always gives me a red error line in twrp "Failed to mount '/cache' (opperation not supported on transport endpoint)

OK so, whenever I try to adb sideload a rom from my pc to my mobile and I go to adb sideload in twrp and swipe it disconnects from my pc and I hear a de de de sounds
That device has an sdcard slot, so just move your desired rom over to that and flash it.
Also, may I ask what rom you had? Lineage os is available for your device (not sure, but if someone compiled twrp, sources are available which means that you can compile it for your device)
