Stuck in Fastboot

Okay so I tried to flash cyanogenmod 11 for the first time on this moto G (US). It bootlooped and I tired to reflash it again and it did the same. There was no way of returning to stock because I had not made a backup. So I tried to flash stock in the bootloader and that didn't work. I went into the recovery and it said 'cant mount /sdcard. So go back into the bootloader and format the sdcard and that doesn't work (which I returned to the recovery to see it not working). I go back and flash twrp thinking that recovery would have something to help me flash a new rom and now I don't even have a working recovery. It takes me straight back to the bootloader and every time I flash a recovery it says Mismatched partition size (recovery) and I am unable to boot into it.
I have no clue on what to do at this point and I need help.

also it says invalid "boot image header!" in red letters

Download vocoderisms TWRP build, extract "recovery.img" from it.
After you have kitkat installed and working:
Option 1, use TWRP without install:
Boot to bootloader (adb reboot bootloader), boot twrp (fastboot boot recovery.img) and install rom from there.
Option 2, install TWRP (have not tested):
Upload twrp zip to phone (adb push Twrp_MotoG_signed_010814_163615.zip /sdcard/), boot to bootloader (adb reboot bootloader), boot twrp (fastboot boot recovery.img), install Twrp_MotoG_signed_010814_163615.zip.

You do know flashing stock again removes root, so it has to be rerooted again ?

Help, MMB29Q update wipes TWRP

Hi all,
Recently I updated my Nexus 5 from Lollipop to Marshmallow 6.0.1 (MMB29Q) - latest build.
everything stock works fine but, once I flash a customer recovery, in my case TWRP it stops working...I get either a startup loop or TWRP gets erased by stock recovery.
I tried various steps ...
flashed TWRP 2.8.7.1 - rebooted to boot loader was able to get into TWRP but, once I reboot system, everything works but TWRP is gone/erased and replaced by stock recovery?
Flash TWRP 2.8.7.1, then flash latest TWRP 3.0, reboot to boot loader and can get into TWRP but once i reboot into system, I am stuck on the initial boot loop.
I have to start from scratch of flashing system and boot etc to get past the loop and it still replaces TWRP with stock recovery.
I can always get into Fastboot but when I go to recovery it seems its being replaced by stock recovery.
anyone experiencing this issue? thanks for your help.

I guess I am doing something stupid but, not sure what...and thanks for your help

If you give more detail on the steps you are taking it will be easier for someone to help. Also, have you tried doing a factory reset when it bootloops?

thanks for the response..here are the details..
I had Lollipop with TWRP 2.8.7.1
yesterday, I downloaded latest build from android site...extracted all files....booted into bootloader and flashed all files..
rebooted - Marshmallow works perfectly...offcourse it not rooted yet or its locedback due to this flash
Scenario:1
So downloaded TWRP 2.8.7.1 and flashed it as recovery, no errors nothing...i rebooted to bootloader and went to recovery to confirm TWRP is there
I rebooted the system - TWRP gives option to root which I said yes so its rooted. I reboot system, this goes into bootloop - I wait for say 5-10 min in this loop mode and I see that adb can recognize the device but nothing else....its stuck in loop
when I force shut down by holding power button for few sec - and go back bootloader/recovery - TWRP is still there
***note*** I did factory wipe in TWRP but that did not fix above condition.
Scenario2:
exact same steps but after I flashed twrp2.8.7.1, I rebooted bootloader and flashed twrp 3.0 as well confirmed twrp 3.0 is flashed and rebooted system - phone start normally no issues - when I restart to bootloader - no TWRP exists, its replaced by stock recovery
Scenario 2, I tried couple of other ways and still the same thing happens - twrp 3.0 get erased.
not sure what I am doing wrong but TWRP doesn't stick
since this is my active device - i flash system.img and boot.img to get the phone to working condition
thanks for your help

Unlocked Bootloader, S Off but Cannot Install TWRP

I'm running the stock at&t ROM with Android 6. I've successfully unlocked the Bootloader, and have taken S Off (paid SunShine!)
When I boot into Recovery Mode I cannot install from SD without getting a Signature Error. When I attempt to flash TWRP via ADB/Fastboot the bootloader will freeze at prompting the Recovery Mode (only way to overcome is to reflash stock rom).
Any ideas? Was hoping to install LineageOS as I read at&t won't be issuing an OTA for HTC as they've discontinued offering the brand.

Set download mode. Then flash twrp with fastboot command. Fastboot flash recovery twrp.img Should workout just fine.

Nope. Read initial post. After flashing handset hangs when Recovery Mode is selected

Perhaps its the version of TWRP you are trying to install? Maybe you might have to try an older version since your on 6.0....?
Also, I have the same AT&T device (unlocked bootloader, but S-ON) and am curious about installing custom bootloader/ROM on this device.
Let us know if/when your able to solve it!

So, I downloaded the Windroid Toolkit at https://forum.xda-developers.com/showthread.php?t=2499926 but now I can't get passed the HTC boot screen. I installed Lineage OS, did Wipe Dalvik Cache, then installed Gapps. But no desktop after install. HELP!

[Recovery Release] Working TWRP for Sony L1 (G3311 Single SIM others to be confirmed)

Requirements:
1. Bootloader Must Be Unlocked.
2. Have a backup of your working Magisk Patched boot.img saved to your External SDcard.​A little INFO:
The Sony L1 recovery seems to be disabled by SONY for some unknown and Probably stupid reason.
I have tried all ways to get the TWRP and Stock recovery to boot up from the fotakernel partition (recovery) but TWRP and even the stock recovery refuse to boot.
Anyway to cut a very long story short I am releasing this TWRP which is 95% functional and needs to be flashed to the boot partition
Working Method/flow:
Make sure you have a Back up of your working Boot.img "You know the one you used to root the device in the first place".
For ease of use You can use this app by XDA dev @wanam (Thread here) app on playstore Here You can also use this app to flash the v5-twrp-l1.img to your "boot" partition or you can go old skool and use dd (Via adb shell) or use the Magisk patched_boot.img you first rooted with..
Make SURE to Copy this working boot.img to your External SDcard.
When you require TWRP flash the downloaded TWRP to your boot partition using Fastboot (cmd's below) or the above app then reboot
You will now boot to TWRP.
Do what you need to do in TWRP.
IMPORTANT:
Remember Just before you leave TWRP go to INSTALL choose your external SDCard choose "image" from the install screen find your boot.img and select "boot" with the little radio button.
Once flashed choose reboot system.
Now when you boot you will be back to normal :good:
Things Not Working:
1. You will not be able to mount encrypted data therefore you would need to FORMAT your data and then leave it unencrypted.
SuperSU and Magisk will disable forceencrypt for you.
2. Does not Charge or show battery % so I don't know if it's actually charging. (Probably Qnovo battery module used by sony)
It will probably work on all variants but I am not able to test that.
It's use is for backups and restores wipes and installs for which it seems fully functional. :good:
Install Instructios.
Boot to the bootloader then
Code:
fastboot flash boot v5-twrp-l1.img
Then
Code:
fastboot reboot
Download HERE v5-twrp-l1.img

Hi @bigrammy!! I have it booting ok, obviously encryption is not working! I was able to do a backup but couldn't boot back into system, just keeps going back to twrp! I had to flashi the patched 3313 boot image from another post to get back into system! Good work though! Tested on g3311

:laugh:
Ok maybe I should update the OP as it seems it's not really clear enough that obviously the boot is replaced by the recovery.
Method would be make sure you have a Back up your working Boot.img You know the one you used to root the device in the first place.
You can also use dd (Via adb shell) or a app from the playstore or better still use the Magisk patched_boot.img .
Copy this working boot.img to your External SDcard.
When required flash the recovery to your boot partition using Fastboot then reboot
You will now boot to TWRP.
Do what you need to do in TWRP.
Then just before you leave TWRP go to INSTALL choose your external SDCard choose "image" from the install screen find your boot.img and select "boot" with the little radio button.
Once flashed choose reboot system.
Now when you boot you will be back to normal :good:
OP Updated let me know if it's clearer to understand now.
Thanks for reporting back. :good:

I'll give it a go! Many thanks! Just one question though. How do I enter recovery mode from then on? Is it still power down, power and volume down yeah?

I don't think you have really read or understood the OP
You are only ever flashing the "boot partition".
When you need to use TWRP you flash the TWRP.img to the boot partition and when your done you flash back your boot.img again to the boot partition as in the OP.
BTW Have you ever been able to enter the STOCK recovery using Power and Volume Down or using any commands
My phone could not enter the STOCK recovery at all let alone a custom one and since no one ever replied to my question about this I assumed this was the case for everyone as many sony devices from 7.0 had the recovery disabled?

I'm unable to get into stock recovery too!

So,
If we don't have a Recovery partition maybe we can
Create one...
Tutorial in here
https://iwf1.com/how-to-re-partitio...-all-options-included-change-size-fs-type-etc
I'll try it if i have time.

I tested twrp 2 times
Worked every time.
I've tried to install superSu.zip via twrp, looked all right, rebooted the phone and now it's in bootloop for over 2 hours...
It's getting hotter... i ca't turn it off
The only thing that works is keeping Power and Volume Up pressed and it looks restarting...
What can i do to revive it safely?

Mate you really need to be careful unless you really know what your doing
You will likely brick the phone if you continue to blindly mess with re-partitioning and the like.
If you were in TWRP which was flashed to the boot partition as directed in the OP then flashing the supersu.zip will simply modify your TWRP.img not your boot.img since TWRP is living in the boot partition at the time you run the .zip hence your looping.
This device has bootloader issues since it will not allow the booting of another partition except "boot" recovery, fotakernel, rdimage, all tested all failed to boot the TWRP recovery and stock recovery.
There is another method used by some sony devices but this will need to be heavily modified for this MediaTek SoC and will require a lot of study and script re-writes.
Spending all this time on a device that's pretty much obsolete before it was launched since it's not planned to receive oreo and Sony 90% locked down the bootloader is kinda futile so use the phone for what it is then throw it in the bin when done in a year or two.

Mate, you are right

I think this one may very well work for the dual SIM also so please try it and then report back with some actual details.
eg: bootloader status, firmware version, your region, etc etc.
Thanks.

Works great on the G3113 model, thank you for developing this! Now hoping to find a custom rom to install via .zip.

This "HERE v5-twrp-l1.img" is working in my Xperia L1 G3312.
But, after installing TWRP, phone does not get into boot normally. Everytime it boots into recovery mode. I think that it needs separate twrp partition. This twrp is overwriting the main boot. If anyone can make separate partition for TWRP recovery. This problem will be solved.

Hello. I ignored all your post like a retard and basically just went to the last step to flash the image. The twrp works but it wouldn't boot into normal mode but just boot to twrp everytime so I downloaded some random boot image I saw online and installed it. Now it's just stuck in the sony logo and won't even turn off. Is there anything I can do or is it rip for good?

No it's only the boot.img Flash the boot.img in this thread https://forum.xda-developers.com/xperia-l1/how-to/root-l1-g3313-magisk-t3693350 if you can get into fastboot that is.
If not then use FlashTool to flash the stock boot.sin and system.sin only. That should get you working again.

In twrp mode, I can do everything smoothly..... but phone does not get into boot normally..... After installing stock boot again, phone boot into normally, but twrp has gone completely..... So, it is clear that boot & twrp partition overwrites each other due to no separate partition.... So, we need separate partition for boot & twrp.... then everything will be solved...

Yes but Sony Disabled the recovery partition (fotakernel) by design so you can not boot from it.
The OP is clear about the need to flash the TWRP to your boot partition and the reason I also give full instruction in the workflow/method but people simply don't read anymore it seems. :crying:
TWRP can be injected into the boot.img so you can boot normally or boot TWRP using the volume keys at boot time but I can't be bothered working on this since Sony are not going to update the Android Version.
While the phone is OK I have far better phones to spend my time on at the moment.

how to backup boot.img without root? if its impossible then how do i root this phone?

Samsung Galaxy A11 in boot loop after root attempt

I hope you guys can help me with this one,
I followed the guide on Magisk website: https://magiskupdate.com/root-samsung-galaxy-a11/
Everything went well up until the final step which is titled: "Re-installing the Magisk App". This is right after I've flashed the patched boot image which was successful, I then proceeded to reboot the phone into recovery mode to reset to factory default and now I get the Samsung logo when I boot the phone, I get the alert that I'm not running official software and then it just loops through the boot sequence again and again.
I tried flashing the boot image again and again but without success.
Did I brick it? Can it be salvaged?
Thanks!

Re-flash phone's Stock ROM to get rid off of all modifications you applied so far.

You haven't unlocked your bootloader, that is why you are getting the alert that says you are not using official software. You have to unlock your bootloader before you can successfully flash a Magisk patched boot.img, it doesn't work on devices that have a locked bootloader.
As stated by the member that posted above me, flash your stock firmware to fix what you have corrupted. Then start over by finding a way to unlock your bootloader, once unlocked, you can try flashing the patched boot.img again. If you cannot find a way to unlock the bootloader, you will not be able to successfully flash and boot the patched boot.img.
