Hello, i tried to update the OS manually on my Desire 610, unfortuneatly i guess i soft-bricked it. I can not get out of Fastboot/Hboot menu. Is there any way to get a working OS on it? Or it is trash now?
Some info:
1. TAMPERED UNLOCKED
2. Fastboot devices : good ; adb devices: not found (tried with original cable, every usb slot, millions of drivers)
Code:
C:\Users\Erik\Desktop\fastboot>fastboot devices
HC46NWS01827 fastboot
C:\Users\Erik\Desktop\fastboot>adb devices
List of devices attached
3. I have no TWRP or CWM. Yes i tried to get twrp via fastboot, but it is doing the same.
Code:
C:\Users\Erik\Desktop\fastbo

4. Tried 2 different RUU, but at 1% it throws back an error.
Can some1 help me?
flash stock recovery with fastboot and use recovery to format. I was having the same issue with my 610.
Hi all,
First of all, sorry for my english...
I've got a problem to root a phone.
I followed this guide :
https://forum.xda-developers.com/android/development/root-ulefone-armor-2-easy-rooting-t3780055
But I just realized, it's for ulefone Armor 2, while I try to root a Armor 2S..
I followed instructions, but I've got a problem on the point 2.
Code:
C:\Users\greg\Downloads\root\platform-tools>fastboot.exe flashing unlock
(bootloader) Start unlock flow
OKAY [ 5.301s]
Finished. Total time: 5.305s
C:\Users\greg\Downloads\root\platform-tools>fastboot.exe flash recovery recovery.img

Downloading 'boot.img' OKAY [ 0.392s]
booting FAILED (remote: 'invalid ramdisk address: overlap with the download image')
Finished. Total time: 0.417s
After few test, who doesn't work at all, I've decide to reboot my phone.
Now, It's stuck on the main screen with this text :
Code:
Orange State
Your device has been unlocked and can't be trusted
Your device will boot in 5 seconds.
And after 5 seconds, the screen go black for one second and return to the message.
And I can't go to recovery mode anymore. Volume+ and Power button don't do anythong but show this "Orange state" screen.
Please tell me there is a solution to unbrick this phone..
Thanks in advance
Try to relock again bootloader with command : fastboot oem lock maybe it can fix that issue but do at your own risk !!!
Thank you for your answer, but the phone is not recognized by the computer at this point.
I can not send command from the PC (adb or fastboot)
Try some key combination keys like :
hold Vol + and plug usb
hold Vol - and plug usb
hold Vol + ; Vol - and plug usb
If that doesn't work , let your battery to be completely empty 0% and repeat process . Good luck
Hey guys,
I have an European LG G5 H850 with an unlocked bootloader. It is my first time rooting, and after unlocking the bootloader, I wanted to boot TWRP once, but I didn't want to install it, but instead keep the stock recovery untouched. So I booted into the bootloader, entered "fastboot boot twrp.img" and I got this message:
downloading 'boot.img'...
OKAY [ 0.462s]
booting...
FAILED (remote: unknown command)
finished. total time: 0.482s
I have absolutely no idea what I'm doing wrong. I made sure twrp.img is referring to the correct file, and I tried both the Android SDK platform tools and the 15 seconds ADB installer, but none of them worked. When I try flashing the recovery with "fastboot flash recovery twrp.img", it seems to work because this appears:
target reported max download size of 536870912 bytes
sending 'recovery' (20900 KB)...
OKAY [ 0.471s]
writing 'recovery'...
OKAY [ 0.198s]
finished. total time: 0.670s
But when I try to boot into the bootloader again, it just gives me the option to do a factory reset, nothing else. So I assume that something went wrong. I have absolutely no idea what it could be, so please help me. I also asked on reddit, but didn't get any answers so far. Any help would be greatly appreciated!
Thanks in advance!

The "fastboot boot twrp.img" command didn't work for me either, but the keystroke to do a "factory reset" -- which is really a keystroke to enter recovery -- did work. Specifically, I
powered down the LG G5 completely (nothing attached to the USB-C port, or battery pull)
with the power off (preferably via battery pulled), held down the Volume Down and Power/Fingerprint buttons
As soon as the LG logo appeared, released and re-pressed the Power/Fingerprint button, all the while continuing to hold down Volume Down
Held down both while the LG logo showed, releasing them after the white screen appeared asking whether you want to do a full erase. Answer yes (Press and release Volume Down until the Yes is grey, then press Power/Fingerprint button)
It prompts you once again. Answer yes again the same way.
At this point after a few seconds, TWRP starts. It hasn't actually done an erase.
This is important: after fastboot flash recovery twrp.img, you need to pull the battery to power down, and then follow the instructions above to enter TWRP. Do not boot into system with the stock ROM after fastboot. It will replace TWRP with the stock recovery at boot time, and in that scenario, the full erase mentioned above actually does erase data and internal storage.
TWRP will on first start change the system image (once you "allow modification") so that the stock ROM stops replacing it at boot time.
If you did boot up the stock ROM after fastboot, you will need to re-enter fastboot and flash TWRP again (power down with USB-C port clear, hold down Volume Up, insert USB-C cable, fastboot flash recovery twrp.img). Then pull the battery with fastboot still running, then boot into TWRP as above.
Unfortunately most writeups aren't crystal clear about the correct sequence of steps. Most cover some steps and gloss over others.
You aren't doing anything wrong.
LG did not put the typical Fastboot commands into the bootloader.
Fastboot flash does not work either.
You need to follow the other methods available on xda to get TWRP on your device.
Edit: woops. That's only with H830. Follow the instructions in the H850 TWRP thread.

Hi guys.
New to the forums. I know that there are three threads that already detail what I am asking for. I just don't get it. I try to follow one of them and it says "run Qfil; install QPst." I would be happy to do that, but I just do not know where they are or how to run them.
Then one of the twrp files (whatever that is) has been taken down because of "gross violations." I cannot figure out how to do what the threads say to do.
Can someone please tell me how to root this thing? Step-by-step. With all the downloads. Thanks for your help.
Feel free to close this thread when a response appears.
Can someone please respond to this now that it is in the correct forum?
@wsmyth
May be this detailled guide helps you: https://www.getdroidtips.com/twrp-recovery-unimax-umx-u683cl-root/
Good luck.
Thank you
Thank you very much. I am starting there!
Help
I followed all instructions. I cannot get a twrp to load.
Good instructions, but I had these problems.
1. There is no link to a TWRP file. I use the link shown, and I get "Stock April Patch" from mediafire. None of the files here have TWRP in the filename.
2. I did go to https://rootmygalaxy.net/root-twrp-umx-u673c, a similar site. It did have a link to a TWRP file to use. Your instructions are identical.
So I turn off the device. I turn it on with power and volume-up button. The device goes to Mr. Android lying down with the message "No Command." I look at some other sites, and it tells me to hold power, and press power-up.
This takes me to Android Recovery menu. On Windows cmd line (ADB and Fastboot folder), I type adb reboot bootloader. The Windows screen responds no device/emulators found.
So I select option on the Android to Reboot to Bootloader. The device boots into FASTBOOT MODE with START at the top. I imagine that this is what the above command is intended to do. For fun, I type the same command above in Windows, and I get the same response. But when I type fastboot devices , I get the device serial number (as shown on the START screen) and the word fastboot.
I imagine the device is ready to install TWRP. I use the TWRP file that I downloaded from the other page (remember, yours and their instructions are identical). I type fastboot flash recovery twrpname.img in Windows, and I get this set of messages:
target reported max download size 26214400
sending 'recovery' (20220 KB)...
OKAY [ 0.650s]
writing 'recovery'...
FAILED (remote: unknown command)
finished. total time: 0.668s
Any help is GREATLY APPRECIATED.

IMO you didn't do anything wrong.
To me it seems that OEM/Carrier did not put the typical Fastboot commands into the boot-loader.
BTW:
To test the TWRP recovery without permanently flashing, run the following:
Code:
fastboot devices
fastboot boot twrpname.img
Follow up
Thanks. When I type that code, I get...

Does it matter that I have no SIM card in this device. on the START screen, I have this...
Press volume key to select, and press power key to select
FASTBOOT MODE (in red)
PRODUCT_NAME - MSM8909
VARIANT - QRD eMMC
BOOTLOADER VERSION -
BASEBAND VERSION -
SERIAL NUMBER - a10b7526
SECURE BOOT - disabled
DEVICE STATE - unlocked (in red)
Is there anyone that can help me on this? Should I take a magnet to the back of the device? Would that help?

Hello there,
A newbie here, trying to unlock a TCL 20B (6159K) phone.
Android 11, November 2021 security patch (MTK Easy Su doesn't work with that, reportedly some vulnerability was patched), fastboot accessible but acting weird.
1. Got fastboot from here.
For some reason it doesn't understand the -i option, but connects with the only phone I'm trying to unlock attached anyway.
VID is 0x0e8d, btw.
2. Got adb from don't remember where about a year ago (for my previous Lenovo phone)
3. Unlocked the Developer Options
4. Checked "Allow bootloader unlock" and "Enable USB debugging" options there (not sure how those are named exactly in English, but I 100% guarantee, I've checked the right ones)
5. Sent phone into fastboot with
Code:
adb boot bootloader
6. Checked the unlockability with
Bash:
fastboot flashing get_unlock_ability
(bootloader) unlock_ability = 16777216
OKAY [ 0.005s]
Finished. Total time: 0.006s
7. Tried to unlock the thing, but
Code:
fastboot flashing unlock
FAILED (remote: 'not allowed in locked state')
fastboot: error: Command failed
and
Code:
fastboot flashing unlock_critical
FAILED (remote: 'not allowed in locked state')
fastboot: error: Command failed
8. Searching here, on XDA forums revealed there's no TCL 20B sub-form.
9. While there are tons of topics on not allowed in locked state, none of those helps.
fastboot oem unlock is seemingly an old way to do things (TCL 20B is a rather new device released WAY past 2015)
TCL is an Alcatel device, not a Xiaomi or some ZUK one, to require an account (haven't found anthing on "alcatel account")
trying to load some recovery from PC that might work failed as well (for the same reason)
Code:
[/LIST]
./fastboot boot twrp-3.6.1.img
Sending 'boot.img' (8932 KB) OKAY [ 0.212s]
Booting FAILED (remote: 'not allowed in locked state')
fastboot: error: Command failed
I've read some TCL 10 phones don't even have a fastboot, but TCL 20B clearly does.
Any Ideas how to unlock the bootloader?
P.S. Maybe a new sub forum for 20B? This got placed into the "TCL 20 5G" one, which doesn't seem right.
EDIT:
Ok, have found how to proceed on my own.
Even rooted the thing.
Go here https://github.com/bkerler/mtkclient, grab the ISO, backup, install patched magisk, patch the boot_a, flash patched boot_a and empty vbmeta_a, erase metadata, userdata and md_udc. Reboot, reinstall pathched magisk.
Don't lock the bootloader to avoid red state.
Huge kudos to mtkclient devs
Hello, i been trying to root my tcl 20b (6159a) but i cant figure how, i follow the instructions of mtkclient. Install it in windows, python, mtk repository, all the process, but when i try to replace boot_a.img it doesnt work from the cmd command, but in the python mtk_gui i can replace boot_a.bin and erase vbmeta_a.bin when i do it from there the cellphone keep in bootloop, i can fix the bootloop but cant root it. If u read this, can you plz be more specific with the steps, and made a little tutorial, its not necessary images or video just some more in deep info how you achieve root, thx
