Hey XDA
I tried to install CM9 today, it fail...
I have unlocked my phone using htcdev.com.
Then I followed this:
If you unlocked your phone via htcdev.com, you must flash the included
boot.img after flashing the ROM in recovery:
- Boot into fastboot, either by:
- Turning phone on whilse holding VOLUME DOWN, or
- adb reboot bootloader, or
- using an option in your recovery (eg. Reboot Bootloader)
- Connect your phone to your PC and copy the boot.img from the ROM .zip
to the same place as fastboot.exe and issue the following command:
- fastboot flash boot boot.img
Failing to follow these instructions on a htcdev.com unlocked device will
cause the ROM to fail to boot.
And now it just stands with a mobile and a ret warning sign. I can get in bootloader, but that's all. I have the CM9.zip on the sdcard but I forgot to run it before I did the above mentioned. I have tried to reset the mobile from bootloader nothing helps
Pleas help me what should I do?
So what is your problem exactly ? Do you have a custom recovery like 4EXT ? It's needed in order to apply the CM9.zip.
None
No i have not installed any recovery app. I cant start my mobile

1.install a custom recovery like 4ext or cwm
(2. Backup current system) this time you don't have to do this since you don't have a working system at the moment.
3. Full wipe (data, system, boot, caches... Not sd card) from recovery
4. Flash ROM zip from recovery
5.flash boot.img via adb
6.reboot
7.done

I'm assuming you know how to boot into fastboot and use fastboot and adb commands. If not, just click on the link in my signature under Helpful links.
Once you're done, just put the attached file in your adb folder, then boot into fastboot and issue the command ;
fastboot flash recovery recovery.img

You will now have the custom 4EXT Recovery. From there, just follow the steps you outlined in your first post, and you should be up and running.
Cheers.
EDIT: I see you already got it working while I was composing my post. Congrats!
@op could you please update the thread title to something like [solved]

Hi everyone,
I've got the no-gui TWRP from the 7th post in this thread and somehow I can't reboot my phone into bootloader: when I use "adb reboot bootloader", it restarts and gets back to the recovery.
Would there be a way to flash the stock recovery over the TWRP using adb (as fastboot can't be accessed) or another way to access bootloader?
Hello! I've tried to root my phone (Moto G XT1541 Europe 1GB) but failed. I got an error when trying to flash the custom recovery. Unfortunately, it has overwritten the stock recovery and it didn't install. So, now I have a phone without recovery and I can't do a factory reset because of that (I think).
So, this is my question: how can I re install the default Android 6.0 recovery mode for my phone?
Also, my phone boots automatically on bootloader mode and I can't re-lock the bootloader because I can't flash anymore either; I got an error because the pre flash validation failed when trying to flash with adb fastboot, but this is minimal issues that doesn't really bother me, but they could be helpful and if someone knows how to get rid of them, I want to know!
I hope someone will help me!

The bootloader cannot be relocked in the Moto G 2015, the best you can do is hide the warning screen. Find the stock image and fastboot flash the recovery from there, or better yet, flash the entire image so you are in a known working state
If you are in Pre-Flash validation, you do not have the correct image for your device... I suggest you post in the "How to flash factory images" thread about returning to stock, if it is possible. You MUST factory default before flashing factory images, if you can't, try 'fastboot erase userdata' and try again.
Flash latest twrp via fastboot and reboot into recovery ,
don't reboot into system,
reboot into recovery manually, then you can enter twrp recovery and can flash supersu 2.62.3.
when you just reboot after flash twrp and reboot system erase custom recovery and save stock recovery, so don't enter fastboot reboot, enter fastboot reboot recovery after flash recovery via pc.
Rename twrp recovery as only twrp in fastboot folder in your pc , not as twrp.img,
But cmd as fastboot flash recovery twrp.img , then no errors ( are you unlocked bootloader ?)

Hey! Thank you! I've been able to flash the TWRP recovery and now I can do a factory reset (and also send sms, which I couldn't do anymore for some reason).
I still have the issue where the bootloader screen appears everytime I turn my phone on, and I still can't re lock my device because I can't flash anything either. I've recovered all of my data, so I think I'm going to stick with that for a moment but maybe I'll try what you said some day.
Again, really thank you for helping me!

Now I understand why my flashing TWRP did not take. I simply rebooted to system and still have stock recovery installed. I was successful booting twrp via fastboot and successfully flashed supersu 2.62.3. Is this step in listed in any faq? I must have missed it.
So after flashing TWRP, do you then power down device prior to manually booting to recovery?

Don't power down, already you are in fastboot mode, you can just enter recovery from that. I forget the reference, but i will search and post.

I get this from twrp official page
Note many devices will replace your custom recovery automatically during first boot. To prevent this, use Google to find the proper key combo to enter recovery. After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don't follow this step, you will have to repeat the install.
In our phone press simultaneously volume down + power button to enter recovery.
I want to root Kruger&Matz Eagle 805 and I came to a block.
specs are here, it's MT8735 tablet with Android 6.0. Almost identical as Lenovo tab2 a8-50
krugermatz.com/en_US/p/EAGLE-805/2377
I've unlocked bootloader with
Code:
fastboot oem unlock
and
Code:
fastboot getvar all
says bootloader is unlocked
I've also tried flashing twrp recovery image for Lenovo tab2 a8-50 and Lenovo Phab2 with
Code:
fastboot flash recovery twrp.img
it flashed succesfully
then I rebooted
Code:
fastboot reboot
and then rebooted to recovery
Code:
adb reboot recovery
Problem is, it rebooted to stock recovery. It is standard android recovery with update, erase, mount /system, etc. but I don't think I can root this tablet with it, without custom rom. I have suspicion it failed to boot twrp.img and fallback to stock img as for a second android image with red mark flashed on screen before stock recovery opened.
My question is how to boot twrp.img I have flashed earlier. I've tried
Code:
fastboot boot twrp.img
but it booted normally to android
On this tablet to get into bootloader you must hold Vol+ and Power. Bootloader is really simple, only recovery, normal boot, fast boot are there. Navigation with Vol+, confirmation with Vol-. Selecting Recovery gets me to stock Android Recovery even after flashing twrp.img
I've also tried kingo root and kingroot without success.
Anyone has any ideas, suggestions how to get twrp working on this device or root it? If you think it's twrp.img problem do you have any tips on building custom twrp.img for this tablet?
I have unlocked bootloader.
I enabled adb debugging from developer settings.
1. adb reboot bootloader
2. fastboot flash recovery twrp.img (tried all of those: peter's, from twrp website, from link on lineageos official thread)
Up to this point everything works fine
3A. fastboot reboot then hold PWR+VOL_UP
3B. Hold PWR+VOL_UP
And at this step I am seeing fastboot logo plus "Unlocked" label at bottom (while in regular fastboot I don't see Unlocked label)
My best guess that something went wrong while booting into twrp, and it fallbacks to fastboot. However I have no clue how to check what's wrong, where to check any logs etc.
Any help appreciated
My advice would be to flash recovery again and manually reboot into recovery and not using fastboot reboot
If this doesnt work flash rom again via bootloader....Then flash recovery....Do Not use fastboot reboot....
Manually holding buttons go into recovery
