[SOLVED] Cannot find BOOTLOADER option?

Hi guys.
I have been trying to get the HS-USB diag/modem ports enabled on my newly acquired HTC One Mini 2.
I read on the internet that i would have to root the device in order to accomplish this.
So I decided to give it a go!
> I have HTC Sync Manager installed on my Windows 10 PC
> I downloaded the TWRP recovery image
> I downloaded SuperSU
> I successfully unlocked the bootloader
> I installed TWRP Recovery like so:
in command prompt i typed - fastboot flash recovery twrp-2.8.7.0-m4.img <Enter>
sending 'recovery' (11460 KB)...
OKAY [ 1.448s]
writing 'recovery'...
OKAY [ 0.492s]
finished. total time: 2.103s
This is where it gets confusing. According to the instructions i am supposed to highlight Bootloader on the device and select Power. But on the device i am still in the Bootloader menu and there is no option for BOOTLOADER. Therefore i am not able to boot into TWRP.
All i see on the device is the following:
FASTBOOT USB
<VOL UP> to previous item
<VOL DOWN> to next item
<POWER>
HBOOT
RAMDUMP
REBOOT
REBOOT FASTBOOT
POWER DOWN
What do i do now? There is no option for BOOTLOADER and cannot boot into TWRP.
Not sure if I am searching using the right words, but I checked the forum and cannot find a solution.
Any help would be appreciated.
Thank you.

that is the BOOTLOADER.:silly:
to enter TWRP
go to HBOOT then enter RECOVERY
if not entering then its messed up . flash it again with new file or try different version.

+1 to Ktivity, you are already in bootloader, with losts of stuff ya shouldnt mess with, just click Hboot, then recovery.
BTW, what is the simlock option for, does that lock the sim??, scared to press it lmao.

It does not do anything unless you have just the correct files in your SD card that define the network and so on. Only service centers and network providers have such files.

Silly me lol
I selected HBOOT then RECOVERY but it goes back to the bootloader menu??
I have already re-flashed it. I guess i will have to find another file to flash.
Thanks for the advice guys

OK guys.
I flashed a different version of TWRP img file and it still does not boot into TWRP?
I noticed something else. When i select HBOOT, for around a two seconds several lines of info are displayed:
SD Checking...
No gift file...
Loading...[0P8BDIAG.zip]
No image!
Loading...[0P8BDIAG.nbh]
No image or wrong image!
Loading...[0P8BIMG.zip]
Loading...[0P8BIMG.nbh]
No image or wrong image!
I pasted a copy of the TWRP img file in the root of my SD card. But still it comes back to Bootloader??
Not sure what to do now?
Any advice guys, please?

Hi guys.
Still not able to load into TWRP. I briefly get the following info:

You are flashing the wrong recovery. Considering the m4 at the end of the image name, this is for the One Mini not the One Mini 2. Which is why you are not able to boot into TWRP.
Get the correct image from here

Hi csoulr666.
Thank you for your reply.
I downloaded the image from the link you kindly provided - recovery-twrp-2.8.5.0.img
When i issue the command fastboot boot recovery-twrp-2.8.5.0.img i get the following response
downloading 'boot.img'...
OKAY [ 1.489s]
booting...
OKAY [ 0.004s]
finished. total time: 1.499s
Then the device reboots into the standard htc home screen and NOT into twrp. At this point the USB cable is still attached to the device and PC. Not sure if this has any bearing on the normal boot??
I performed the above steps several times, but still the device boots up to htc home screen and not twrp.
In bootloader, i also selected HBOOT, i briefly get the following info:
SD Checking...
No gift file...

No image!
Loading...[0P8BDIAG.nbh]
No image or wrong image!
Loading...[0P8BIMG.zip]
Loading...[0P8BIMG.nbh]
No image or wrong image!
i then select RECOVERY, however the device stays in bootloader??
Very frustrating to say the least.
Am i missing something else?
Thanks for the advice up until now.
P.S please excuse me, i am a newbie so not that much familiar with rooting.
Cheers.

if you dont want keep seeing this just remove SDCard while you performing the actions.
try this recovery instead
its normal the device boot into the rom unless you press the buttons to get into bootloader.

Brilliant.
I finally got into twrp with this recovery provided by kativiti. I have now successfully flashed supersu zip.
Wow that took some doing.
OK so now i need to find a suitable ROM that will help me answer my initial query, Enabling HS USB Diagnostic port. I was able to enable the hs usb diagnostic port on a Samsung just by installing Kies software. But was not able to get the hs usb diagnostic port enabled for several rooted Sony devices. I guess all the custom ROMs will do that?
Anyway I really appreciate the assistance i've had from all you guys.
Cheers and big thank you.

not sure what you asking and for what but after a search i found this:
open command prompt and type
adb devices (if your device shows continue)
adb shell
su -c 'setprop sys.usb.config diag,adb'
nothing happened on mine but i don't have HTC drivers installed. All you need in here

Hi kativiti.
Yes, this is exactly the adb setprop command i'm sending but nothing is happening. Usually, after issuing this command in device manager on my windows pc, new ports open up with exclamation marks and then either windows installs the drivers automatically or I have to do it manually. Only then I should see the newly installed HS USB diag port. I also noticed that the setprop command has different variations, therefore i am looking at tweeking the command. Back to the net i go.....
Previously, I was able to enable HS USB diag port using the above adb command on the Xperia Z and Samsung Mini S4. But I've not been able to activate HS USB on Xperia Z3 and now HTC One Mini 2. I was under the impression that if I rooted and flashed a custom rom onto the HTC One Mini 2, all developer features would be automatically available, especially the HS USB diag port??
To compound the misery, after much reading on rooting and flashing for HTC One Mini 2, I flashed cm-NostromoPop-v2.0-20150430-1330-memul.zip and open_gapps-arm-5.0-nano-20160401.zip. Thankfully the device is not bricked. However, now i get the following problems
When accessing Google Play Store - 'Check your connection and try again'
'Google Play Services won't run...' message repeatedly appears
I cannot boot into twrp recovery so that i can flash another rom
I read on the net that installing the wrong GApps file produces the above google problems? Could i have installed the incorrect GApps file?? Not sure how to verify this? Could the rom i installed be incorrect?
And what can i do to get into twrp recovery again? Not even the twrp recovery image i earlier flashed and successfully booted into has helped this time.
I am rigorously searching the net for answers, to no avail thus far.
Ahh the joy of messing with a phone. I'm very tired but will keep trying lol
Any help would be warmly welcomed.
Thanks in advance.

Start again...
first clear cache
fastboot erase cache
then flash recovery again.
Make sure that you get ROMs from official sources.

OK so i cleared the cache through adb (fastboot erase cache)
i then successfully flashed twrp recovery. However, instead of the device rebooting to twrp recovery, all i see on the device is the cyanogenmod icon with a circle gradually appearing and disappearing around it.
I have attached a number of photos in sequence (DSC_000009.jpg, DSC_000010.jpg, DSC_000011.jpg, DSC_000012.jpg) showing the circle around the cyanogenmod icon.
Why has this cyanogenmod icon appeared? Is cyanogenmod updating? Or is the device bricked?
Also, is this the link for the official downloads - https://wiki.cyanogenmod.org/w/Devices
Appreciate your advice please.
Thanks again.

you are stuck in bootloop because your ROM is corrupted. Remember you need to use the button to get into bootloader and then recovery.

OK i did a little trial and error:
I simultaneously pressed the power and vol down button, however device did NOT boot into bootloader
I then simultaneously pressed the power and vol up button and device rebooted, but then went back into boot loop
Finally i simultaneously pressed power and vol up button and device started to reboot (screen went blank) and i immediately pressed vol down button, now it booted into bootloader
I then selected HBOOT > RECOVERY and it booted back into bootloader
So i decided to flash twrp recovery when in bootloader and again it went into boot loop
Unfortunately i am back to square one - in bootloader
I can now boot only into bootloader and not to normal UI. So i guess the rom is corrupt.
It's probably a silly question - Is there a way to install custom rom through ADB??
Thanks again

you can use ADB push but you need TWRP for that.

OK so after much fretting i managed to get my device working.
I managed to boot into bootloader and then flashed an earlier version of twrp and it immediately booted into recovery.
From here i wiped cache, system...... and then installed CM12 with corresponding GApps.
Device now working...PHEW!
OK so now back to trying to get HS USB port activated using ADB commands, which i am trawling the net to find. I just don't understand why it is possible to activate HS USB port in Windows for Samsung and Sony, but not on this HTC One Mini 2?? The ADB setprop command you listed earlier is usually the one that triggers windows to open up the HS USB Diagnostics port, but it is not happening with this HTC One Mini 2? Anyway, i'll keep checking the net.
I have added an image just to show what it is i am trying to activate - Qualcomm HS USB Diagnostics Interface Port
Once again many thanks for your assistance kativiti.

Stuck at booting into custom TWRP recovery

Hello, this is not the first time I'm rooting an Android phone, and I had no problems with any of my past attempts. However, this situation with Huawei P9 EVA-L09 has given me a headache...
I have originally followed this guide:
https://theunlockr.com/2016/12/06/root-huawei-p9-p9-plus/
(which appears to have skipped tiny but crucial part on flashing twrp - so I don't recommend)
Everything was going fine until I have flashed TWRP on my still NOT-rooted Huawei P9 EVA-L09 (adb reboot bootloader ; fastboot flash twrp-3.1.0-0-eva.img) successfully:
target reported max download size of 471859200 bytes
sending 'recovery' (22462 KB)...
OKAY [ 0.639s]
writing 'recovery'...
OKAY [ 0.302s]
finished. total time: 0.944s
After this I have used the command fastboot reboot and phone started normally. However when I try booting into custom TWRP recovery I just flashed and get the usual bootloader unlocked warning! I either get stuck at Phone is booting now... or I get into original EMUI Huawei eRecovery.
Did I do something wrong? What do I do after flashing TWRP?
I have read somewhere that original EMUI ROM maybe rewrites custom recovery if OS(ROM) boots before you entered recovery so could this be my problem? How do I reboot directly into TWRP from fastboot to avoid booting into the ROM?
Also, what is the correct way to boot into TWRP, what key combo? Since I get phone bootloader unlocked warning! right after powering on the phone, do I press the combination right away or after the warning shows up? I've been trying to boot custom recovery for hours, this is just silly...
Put simply I can't seem to get into TWRP I just flashed so I can install SuperSU from SD card to root my phone...
I have tried older TWRP version too, didn't help.
Phone is Huawei P9 EVA-L09, Android 7.0 EMUI 5.0, tried both TWRP versions from here: https://dl.twrp.me/eva/

After flashing twrp you should special reboot to twrp. Adb command reboot with pushing vol + and at the same time disconect usb cable. Check this on twrp official

How will I do anything with adb if I'm in fastboot mode? Only fastboot commands work...
Maybe you thought fastboot reboot and key combos, but which combos are correct? The TWRP official page says I should Google for key combo (how come they don't know lol, I guess they had to test the bloody thing?) and I have googled but some people say it's power down, some up, some both, what the f? When I think I got it right I get stuck on Device is booting now...
I've just tried this:
Flash TWRP 3.1.0-0-eva again over ADB
fastboot reboot + VolUp held and USB cabble plugged out
Stuck forever at Device is booting now... (below the Unlocked bootloader warning).

Ofcourse fastboot.

Solved this part by using this TWRP version:
https://forum.xda-developers.com/p9/development/twrp-t3565703
The button combination to enter TWRP on P9 EVA-L09 EMUI 5.0 is - Power and Vol+ buttons held while fastboot reboot command is issued in CMD and USB cable unplugged, all at the same time. After device vibrates you should release only the power button. When you see 'Device is booting...' you can release Vol+ too. TWRP should now boot.
Now on to root...
Solution:
https://forum.xda-developers.com/p9/how-to/twrp-3-0-2-0-n-t3506947/post70927601#post70927601

After flashing EMUI 5.0 EVA-L09C432B378 and update B378_update_data_full_hw_eu and wiping my phone (wipe data/factory reset - yes this was probably stupid without backup or anything), it boots fine but there is no keyboard app, only useless voice control. This wouldn't be a problem if I could get past EMUI welcome screen and install keyboard.apk manually but it won't allow me to use the phone until I log into Google account which I used on the phone before factory reset. It doesn't allow me to access SD card or anything either, doesn't even ask for permission when plugged in. Flash process also rewrote TWRP recovery so I only have eRecovery atm (bootloader is still unlocked but this is useless at this point). I also cannot enable Dev options/USB debugging or reach phone settings (all reset to default obviously) at all because I can't get past EMUI welcome wizard without a keyboard... I can use dialer keypad in emergency call mode before starting the welcome wizard, for example I just checked my IMEI, but most other commands don't work.
Any ideas? I read that there is a rollback version which will enable me to flash the previous EMUI/Android6.0 version, but which rollback is right for my device European EVA-L09C432B378 phone? I don't want to get into more trouble by flashing a wrong file...

Hello, my phone is stuck now on the "Your device is booting now" state, can you help? I did exactly what you said above

Maybe you thought fastboot reboot and key combos, but which combos are correct? The TWRP official page says I should Google for key combo (how come they don't know lol, I guess they had to test the bloody thing?) and I have googled but some people say it's power down, some up, some both, what the f?

I have the same matter here with my Huawei Nova 2i. I have flashed sucessfully TWRP but cannot enter TWRP mode to install root. When I hold Power + Vol+, it stucks on "Device is booting now..." forever. And for normal power up, it show the EMUI recovery. I've tried so many way but useless. [TWRP][P9][3.1.1-1][EMUI 5.x/AOSP N][DECRYPTION SUPPORT] by OldDroid did't help. Is there any version of TWRP can help my Huawei Nova 2i???

Hello
Thank you all for the help
I think I did something really bad... I have rooted phone and TWRP installed on a P9, but no ROM. I was trying to enter TWRP recovery and I did "fastboot oem relock XXXXXXXXXXX".
Now I see only the white screen with little andoid robot saying:
Attention!
Please update system again
...
Error!
Func NO: 11 (recovery image)
Error NO: 2 (load failed!)
Am I screwed ? :0
Thank you so much in advance

Don't understand why you thought that relocking bootloader would help you to enter TWRP, but it's too late for discussions about.
Relocking bootloader trigers hard reset, but hard reset fails if you don't have stock partititions (eg, TWRP means you don't have stock recovery, root means you don't have stock boot partition).
You didn't have and you don't have OS (hence you will not be able to Unlock OEM, and if TWRP was deleted, you can't flash it - TWRP is usually needed to recover)
You should first find out what you really have now :
Press power for long (if needed, even for half a minute), to make sure phone switches off. Make sure USB is disconnected. Boot by Vol+, Vol- and Pow: does it boot to TWRP, eRecovery or to nowhere?
Turn off again, connect by USB to PC (same USB cable, same PC you previously flashed TWRP from or locked/relocked your bootloader from). Power on by Vol- and Pow, does it boot to Fastboot and does Fastboot say that FRP and Bootloader are locked or unlocked.
If you still have TWRP (first test) or if Bootloadr and FRP are unlocked (test 2) in which case you can flash TWRP -you are good, you can try some methods to install stock ROM through TWRP, like HWOTA method:
https://forum.xda-developers.com/showpost.php?p=75787156&postcount=3
If you have eRecovery, you can pull out SD card and pepare it for DLOAD instalation of ROM.
Bad if you don't have any recovery and FRP and/or Bootloader is locked. Maybe DC Phoenix can help you then

Thank you so much for your answer @zgfg
Thanks to you I understood that the phone was never really turning off no matter how long I press (I tried for 1 min approx), so I left it to discharge and when I plugged in I pressed the 3 buttons and it "boots" to EMUI eRecovery. Then I tried the download and restore but it failed of course. I reboot with USB and Vol- and Pow, and it loads the white screen with
FASTBOOT&RESCUE MODE
Please Connect Usb Cabke ti
Your Computer and Open Hisuite
...
Android reboot reason:
coldboot
NA
volumnkey_down_press_process_func
...
PHONE Relocked
FRP Unlock
So I understand that I am in this case right?
"If you still have TWRP (first test) or if Bootloadr and FRP are unlocked (test 2)"

Thank you so much for your answer @zgfg
Thanks to you I understood that the phone was never really turning off no matter how long I press (I tried for 1 min approx), so I left it to discharge and when I plugged in I pressed the 3 buttons and it "boots" to EMUI eRecovery. Then I tried the download and restore but it failed of course. I reboot with USB and Vol- and Pow, and it loads the white screen with
FASTBOOT&RESCUE MODE
Please Connect Usb Cabke ti

Android reboot reason:

FRP Unlock
So I understand that I am in this case right?
"If you still have TWRP (first test) or if Bootloadr and FRP are unlocked (test 2)"
If this is the case I will try this method tomorrow. Thank you so much again!

With FRP Unlocked you can try to unlock Bootloader - it will fail to hard reset, but if it unlocks, you will be able to flash TWRP.
With TWRP you can try - download and use stock ROM for your model:

It did unlock FRP I think, it's now
PHONE Unlocked

I did a "fastboot flash recovery twrp-3.1.1-1-eva.img" but I still can't access TWRP
Sorry if it is a noob question, I'm learning and I looked for an answer all day long :facepalm:

Are you on P9 Nougat?
Better use TWRP from here
https://forum.xda-developers.com/showpost.php?p=75787111&postcount=1
Nevertheless, what does it mean you cannot access TWRP - does Fastboot on the PC side report successful flashing?
If so, then
- keep USB connected to both phone and PC
- press and keep pressing Vol+, Vol- and Pow on the phone (it will not reboot yet)
-execute fastboot reboot
and immediately after disconnect USB
-keep presing three buttons as above, release Pow when it shows booting
You must be quick (with USB disconnectibg) and do exactly as above - with that phone should reboot to TWRP
If you don"t get it, phone will reboot to System and you will loose TWRP (you will have to flash TWRP agai)
Only when you first time upon flashing enter TWRP as above, TWRP will remain and later you will be able to enter TWRP as usual

Solution
For anyone pretty much, who has ****ed up his Huawei P9:
I got to the state where I could only enter Fastboot mode (Press vol- and connect power cable). When I tried to start the phone / go into recovery it would only display the "Your device has been unlocked and can't be trusted" Message. My mistake was to relock the bootloader in an attempt to get the recovery to work.
I looked for hours for the answer, here is what worked for me:
follow this tutorial (the "update firmware" part)
German
English
But with real precision, every step.
If you have a european unbranded L09 you should be fine using the firmware you can find on this site:
https://thedroidguru.com/download-install-huawei-p9-b394-nougat-update-europe/
if not you gotta find the full firmware (3 files!!) yourself - good luck!
If you only want to go back to stock you should be fine afterwards.
If you want to install twrp for root/custom rom/... follow these steps after installing twrp with the tool:
Upon flashing TWRP, FIRST THING YOU MUST DO is rebooting to TWRP. If you don't do that, stock Recovery will ovewrite TWRP.
Find instructions in the TWRP threads how to enforce immediate booting to TWRP, upon you flashed it:
-Type on the PC: fastboot reboot -but don't press Enter yet.
-Press and keep pressing Vol+ and Power buttons together on the phone
-Press Enter on the PC and then immediately unplug USB cabel.
-When phone shows Booting, release Power but keep pressing Vol+. button
Hope this helps, I don't take responsability for anything, happy flashing!

Phone can't boot stuck at "Your device is booting now" Please Help

Hello, I wanted to install TWRP and ROOT my phone. I flashed TWRP using adb terminal. But when I tried to boot into TWRP it was stuck on "Your device is booting now..". Then if I held the power button for few secs it rebooted normally. So I tried to google it and I found adb command that reboots to recovery
Code:
adb reboot recovery
. When I executed the command it rebooted to the "Your device is booting now.." screen and it stays like this forever. No button combination works to reboot the phone if i hold power button it reboots shows honor logo and then shows the "Your device is booting now.." screen. I waited for the battery to drain and then i put the phone on charger and when I tried to boot it, it was the same. Now when I try to reboot the phone it shows ultra low baterry symbol and then boots to "Your device..." screen.

Which twrp you flashed? Check the correct twrp in my signature for honor 5C repository.

Hi hassanjavaid8181
I think I have the same issue here, phone is stuck on "your device..." screen forever and it's impossible to do anything else (reboot ends up on the same screen).
How is it possible to flash twrp or stock recovery if we are stuck on this screen ? Fastboot doesn't see the phone...

Did you try all method to going in fastboot.by adb fastboot command or by pressing vol- and power button?

Hi guys, thanks for your replies.
I somehow managed to boot to fastboot after waiting for the battery to go out completely. From there I used the following commands in ADB from the extract of a stock update.img :
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot reboot
And it worked ! The first boot was veeery long and now it's normal again.
Now my last concern is that I still have bootloader unlocked. As I wish to come back to factory state and avoid the warning message on boot, do you guys think it's safe to re-lock bootloader ?
I'm kind of scared to try anything else and screw the whole thing now
Thanks again for your support

Can you please explain to me how did you managed to boot into fastboot? I tried waiting for the battery to drain completely. Now I can't fully charge my phone. When i connect it with charger. It starts normally charging like it would with 0% battery then after a few moments the honor logo shows up and then the screen "Your device.." shows. When I try vol- and powerbutton it vibrates and shows the red lightbolt then after few moments it boots the same way into the your device screen. When I connect it to the pc it doesn't react. I don't even hear the classic windows beep sound.

When I remove the usb cable it's still the same. When i try to press the power button it vibrates shows the low battery red lightbolt and dies. If you mean by erecovery emui recovery, then it looks like it's not installed.

You need to press power + volume down key to boot into fastboot. Keep trying 4-5 times sometimes it takes due to wrong press

So I managed to get into the fastboot. Where can I get boot.img, recovery.img and system.img? I have downloaded some update.zip files from this russian site (first 5) http://hwmt.ru/hwmtsite/firmware-database/?firmware_model=NEM-L21&firmware_page=0. But I don't have boot, recovery and system images in these zips.
I also tried reboot in fastboot but its still the same:

Meaning the fastboot is accessible.
Now you have firmware zip, extract it amd you will get few files. Use dload method as given in my signature and you are good to go.
Else use Huawei extractor and browse to update.app you just got in above downloaded zip. You will get boot, recovery, system img you need.

I downloaded some firmware versions and extracted them. I don't know which is for my device. So I tried one of them. I flashed boot.img and recovery.img but I din't flashed the system.img, becouse it was too big. When I tried to reboot the phone it was the same. The fastboot was no longer accessible. I put the phone into servis but they didn't fixed it. it's the same but I can enter erecovery

Flashed Wrong OS; 4x Won't Power On

1. I have successfully requested and unlocked my 4x.
2. I wanted to install: https://forum.xda-developers.com/xiaomi-redmi-4x/development/rom-2017-08-07lineage-14-1-t3653016
3. First step, install TWRP following this: https://twrp.me/xiaomi/xiaomiredmi4x.html (Fastboot Install Method (No Root Required)
3a. Using version: twrp-3.2.1-0-santoni.img as downloaded from the twrp site
3b. After many reboots and tries, finally get into TWRP. Password not accepted at first, press cancel, get to TWRP menu.
3c. Wipe->Advanced Wipe->System,Cache,Dalvik's/Art cache. Swipe, then get errors. Try again, errors. Press reboot option.
4. 4x OS will not boot. It is stuck in endless cycle of Mi logo, and recovery/TWRP boot (vol+ and power) does not work. Only way to break Mi logo is fastboot (vol- and power).
5. Try to reset phone so I can start entire process (starting at 2) all over again following this: http://en.miui.com/a-234.html
5a. Used this version: http://update.miui.com/updates/v1/fullromdownload.php?d=mido_global&b=X&r=global&n=
5b: Edited the flash_all.bat following this: https://www.youtube.com/watch?v=_osMF9EubhI
5c. Left fastboot mode, device will not power on at all.
And as I type this I realize I put on the "Note 4x" instead of the "4x" version. I should have used this version: http://update.miui.com/updates/v1/fullromdownload.php?d=santoni_global&b=F&r=global&n=
As a potential next step I've identified: http://en.miui.com/thread-693884-1-1.html
I need some expert guidance at this point. Thank you.

Recovery is both volume keys plus power.
Maybe you should reflash firmware as well(v32).

you can try it
download and install last version ADB https://dl.google.com/android/repository/platform-tools-latest-windows.zip
enter to TWRP both volume + power. after choose Advanced - ADB Side load .. run it
run command line on PC after: adb sideload /path/to/rom.zip
wait while rom will be installed... press Reboot to System (if TWRP don't reboot byself)
wait near 5-10 min for first time rom startmust work.

I have gotten to recovery with just vol+. Regardless, the phone will not turn on from either combination.

vol+ and power ... have menu for reboot to Fastboot and Recovery .. choose it for reboot to TWRP and flash phone or in Fastboot and flash with Miflash

you know,, if you install twrp,, the combination key vol up+power cannot work,,, he work if you hold vol up+vol down+power until MI logo then realease.

This sounds a hard brick to me.
Every replies about Fastboot and Recovery are pointless, because he cannot start the phone in Fastboot.

either it's hard bricked or motherboard stopped working after the wrong flash.
i think you should give it try on test point method once as you have mentioned in this thread (do it on your risk) or you may have to visit service center since any button combination isn't working for you.
what is the status of device when connected to PC or on charge ? is it charging ? does led light blinks ?

I used the guide I posted in OP to fit it, though it wasn't easy. Gonna try lineageOS one more time. Thanks to all who tried to help.

I had this same. I saved my phone using this toturial:
and
http://en.miui.com/thread-693884-1-1.html
Be careful with the screen and sim tray!
My phone was 100% dead (no fastboot or recovery). I have tried everything before and only that works.

Having some trouble rooting now sure where is the problem

So I followed this guide, watch?v=eBAzsEw-QVsAnd, He used an auto flashing program, got to the step where you flash the recovery, it worked, the ADB was recognized and the writing of the recovery was successful.
But, when I tried booting into TWRP (by power + vol-up) I just get a black screen for a few secs and then the mi logo again.
Also, I manually installed TWRP 3.3.1 and still the same thing
Any suggestions?

When you restore the phone try using the latest TWRP from here https://forum.xda-developers.com/k2...icial-twrp-xiaomi-redmi-t3944363/post79823568
Copy the TWRP image to the adb/fastboot folder and rename to TWRP.img.
No need to use any tools, just boot into fastboot connect to the PC then in command prompt navigate to the adb folder and use
Code:
fastboot flash recovery TWRP.img
After installing boot immediately into TWRP and flash what you need.
In fastboot still press and hold power and vol+ until it vibrates. Then let go of power and keep pressing vol+ until TWRP boots
