[Q] HTC One in a boot loop

Hello.
I was in the process of upgrading my HTC One from 4.2 and successfully unlocked the bootloader. But thereafter my phone just constantly reboots. It shows the HTC splash screen for about 10 seconds and the reboots again.
I am able to go into the fastboot screen (see screen shot). But when I select Recovery, the phone gors to the next screen - displays "Entering Recovery" - and nothing else happens thereafter.
Can anyone please help? Have looked at other such questions and tried but nothing has helped.
Thanks

I'm not sure you did ever flash a custom recovery!
1. Put your phone in fastboot from the bootloader meny. You already did this while rooting, so you got it already!
2. In your "SDK-tools" folder that you used while unlocking the device, put [nameofyourrecovery].img I recommend you to install TWRP 2.6.3.3, as it is the best one for flashing kitkat and lets you do this if you wish I cannot give you a link as I am a new member, but search google for TWRP 2.6.3.3 and you will find it. Make sure it is .img and not .zip!
3. While in fastboot, open a command prompt in the ADB folder.
4. To flash your custom recovery, type
fastboot flash recovery [nameofyourrecovery].img

Does not help. Used 2.6.3.3, the flash process went fine, then Recovery displays "Entering Recovery" - and then again bot loop.

You have an M7CDWG, twrp is for M7_U & M7_UL models, if i'm not mistaken. Start googling for M7CDWG, it's a completely different phone than the U / UL phones.
and you need to "fastboot erase cache" after flashing recovery

Dear nkk71
Many thanks. I used your suggestion and rooted as per #9 in this post:
http://forum.xda-developers.com/showthread.php?p=45427332
I installed Chinese recovery followed by TWRP recovery. I was abe to Recover and reach TWRP manager 2.6.0.0.
Can you please suggest what next to instal?
If I reboot I still go into reboot loop, but can now reach TWRP manager.
Thanks

Not really, don't know much about your model. You'll need to find a ROM compatible with your device; if it doesnt specifically say it's for your device, then most likely it isn't!!
I think there's a Maximus HD ROM for your version, but i have no idea where.

Did you..
Aside from flashing a recovery and rooting your phone, did you make any other modifications or flash any other partitions?
If no, then wipe Dalvek cache from TWRP. Boot into TWRP and select Wipe. Select advanced. Select Dalvek and Cache. Wipe power down. then power on and see if it will boot.

Yes, Maximus has a ROM for dual SIM, Flashed, all went well, but the reboot loop still exists.
Thanks

Did as you mentioned - all went fine. But the reboot loop simply does not go away.

i had a similar problem last week with a One, a friend bricked his One by flashing "???" Dont know exactly whar he has done.
The phone had boot loops all the time.
my solution was:
- connecting the phone with the usb cable to my pc.
- started the phone into fastboot usb mode
- started cmd at my notebook
- change to the directory which contains adb and fastboot
- execute: fastboot erase cache
- restarted the phone
the phone starts normally into ARHD 40.3
perhaps it works ...

Unlocked Bootloader, Can't root? [XT1096]

Not really sure what I'm doing wrong. Last rooted phone was a Nexus 5, and that was of course painless to root and flash ROMs to...
I'm using a Verizon XT1096 with 5.1 on T-Mobile.
So I was able to get the bootloader unlocked via Motorola's website, now that Verizon is allowing them to do so. No problems there. My problem now is that I can flash a recovery, but if it reboots, the recovery is gone. And I can't get any recoveries to flash anything. I can't push an apk, root zip, or even a ROM. Says Installation Aborted, with no other error codes. Even tried CWM and disabling Signature Checking, which gives me more info, saying that the footer is mismatched. Phone does say the bootloader is unlocked though so that shouldn't be it...
Honestly, I'd just like to get it on CM12 until I can get a Nexus 6P.. Can anyone tell me if I'm doing something wrong? Or is there just no way to root yet? I figured even the XT1095 CF-Auto-Root method would work for 5.1, but no dice..
Not sure what to do here. Please move my thread if need be. Don't post here much...

I followed the instructions on the TWRP website (link below) and it worked flawlessly. One thing you have to do is, after running the "fastboot flash recovery twrp.img" command, make sure to manually scroll on the phone and reboot into recovery. Hope that helps...
https://twrp.me/devices/motorolamotox2014.html

There is a partition mismatch. So do this. Download supersu and place it in the phones memory. Boot to fastboot mode and then fastboot boot recovery.img rather than fastboot flash recovery.img. You will boot to twrp, install SuperSU then download twrp from the playstore and install thru the app. It works, that's how I did it. Also when booting to recovery from the fastboot menu choose recovery with the vol up key rather than power button.

I thought I tried that but maybe not. I've read that some stock ROMs can and will overwrite the recovery upon booting, but I could be wrong. I'll look at that when I get home tonight.

Thank you, I'll try this tonight when I get home. This may solve it. I think I remember the bootloader spitting something out about a partition mismatch.. Will report back as soon as I try it.

So I went ahead and tried both your guys' methods.
Oraixearl, I figured your solution would work, but it actually didn't, to my surprise. It returned no results, as the root zip didn't end up doing anything.
RepeatUntilTheEnd's solution worked here. I guess I didn't try rebooting the phone after flashing the recovery, before going into it..
So here's what I did.
1.) Boot into bootloader
2.) Fastboot flash recovery [recovery.img]
3.) adb reboot bootloader
4.) Used keys on phone to go into recovery,
5.) Flashed root.zip
6.) Booted into OS, and ran root checker. Worked.
7.) To my surprise, TWRP stuck around, too.
Thank you guys!

Redmi 4X bootloop after installing TWRP?

Hi,
I'm having a bit of trouble. I had a brand new Redmi 4X, and I was advised to install TWRP, root it, and install the Xiaomi.eu rom until LineageOS is released. I unlocked the bootloader, flashed TWRP, managed to get into it once and now I can't do it again. When TWRP loaded it asked me for a password for decryption but it let me just skip it it seems (not sure if that is the problem) but now I can't boot normally, I can't boot into recovery, but fastboot seems to work okay. How do I go about fixing this?
I've tried reflashing TWRP but I still can't get to it, and I don't really know enough about this stuff to know where I've gone wrong.
UPDATE - I think this is to do with dm-verity and having the stock kernel installed. Now it's too late to undo what I've already done, so I hope to god that someone knows how to fix this.
UPDATE - Right, the problem is solved I think. I had to do an awful lot of googling, and I'm not entirely sure what it was specifically that fixed it. But I found a guide that taught me the fastboot command "fastboot boot twrp.img" which saved the day. Even when my phone wouldn't let me into recovery, it allowed me to flash a no-verity.zip which i think is what allowed me to boot, and it allowed me to flash superSU.zip and then the ROM I was aiming for. And now I've booted into the ROM successfully and hopefully I am rooted and all is well. Plus I can access TWRP as normal now.
Any help would be greatly appreciated

Can you boot into TWRP by pressing the buttons so that you boot directly to TWRP??
Have you tried Command Prompt to boot with commands in to recovery??
And if you get into TWRP you should have everything on the SDCard and then just
format all things except SDCard and then flash from SDCard everything
That is what I would try..and yes it ask for a password but just skip it to get to it
If you can get into TWRP to flash from SDCard then you good to go..if not
Google all the commands for CMD..and plug your phone to the PC and flash everything with the
commands.....
Let us know what is working and what not and what steps exectly you are doing
EDIT
Turn off your device > Press and hold “Power” and “Volume +” buttons at the same time.
After short vibration signal release the power button and wait for TWRP to start.
To boot in stock recovery open “Update” app.
In the setting select “Boot in recovery”.

Thanks for the reply. I can't get into TWRP. Even if I could get into TWRP how would I get files on the phone to flash them?
Is it possible to flash any rom from the pc directly and if it is will this possibly help? I think it's not booting because the kernel is still stock.
I'm not sure what you mean in the edit, how do I boot into stock recovery without being able to boot the phone (and when I have already flashed TWRP)?

Hii
I just have been reading about this bootloop
Go over here and read all of the 6 pages..will not take much time but could help you out much
https://forum.xda-developers.com/xiaomi-redmi-4x/development/official-twrp-3-2-1-0-xiaomi-redmi-4x-t3718217

Hey, I have exactly the same problem. Latest stock rom, flashed twrp in fastboot and got into the boot loop. Nothing works. I can only enter fastboot. What exactly did you do then? What is this no-verity.zip? I can't find anything about it.

I had a problem
I unlocked bootloader then installed redwolf recovery and took a nandroid backup. After that i rebooted to system but stuck into bootloop, could not boot to recovery, could not boot into system, So the only thing worked was that i flashed fastboot rom with mi flasher. And syccessfully rebooted to system with bootloader locked and stock recovery. So, if anyone have same problem you can do the same. How do i install recovery safely again? Should i use TWRP only? Should i flash v3.1.0 with lazy flasher or v3.2 directly without lazy flasher? I don't want to stuck into bootloader again, have to get all data deleted.

Cant flash TWRP

Trying to flash TWRp after unlocking bootloader. First time i tried it, said successful but booted to MIUI recovery
2nd time i tried said again successful, booted to TWRP, formatted data.
Phone then wouldnt reboot to TWRP. Instead it going straight to fastboot. I keep trying to flash again, every time saying successful, then it just boots to fastbooot, not recovery. Any ideas, phones dead at the minute

The best way to recover the phone in your situation is to fastboot flash MIUI.
Get the latest MIUI fastboot ROM for your phone from here
https://xiaomifirmwareupdater.com/miui/raphael/
Install it using this guide from the official MIUI forums
https://c.mi.com/oc/miuidownload/detail?guide=2
If you see a blank page on a mobile browser, set it to view in desktop mode, for this page.
Make sure in step 5 you change the option at the bottom of the Mi Flash Tool to 'clean all' before hitting the Flash button.
MIUI will restore stock recovery when it reboots, so you need to do something to fix this. Flashing Magisk or a custom ROM will automatically preserve TWRP.
If you plan to keep MIUI and do not want Magisk, then you need to flash the vbmeta patcher from here
https://forum.xda-developers.com/k2...icial-twrp-xiaomi-redmi-t3944363/post79823568
You need to flash TWRP, then immediately boot into TWRP.
Code:
fastboot flash recovery <path to twrp>
fastboot oem reboot-recovery
At this point you need to flash something in order to preserve TWRP (either a new custom ROM, Magisk, or the vbmeta patcher)

Cheers. You know this is all familiar. Pretty sure i had the same trouble 3 years ago with my mi mix 2
Anyway, lots of hiccups on the way along with this solution. Got to the point now where it says its flashing but it never stops.
EDIT: Bit more research, shortened the path names. Got an error. Commented out device name, got a different error. Switched to USB 2.0 port an FINALLy im back up and running.
Thank you so much for the help.

Phone goes into fastboot mode after I reboot, can't get into system or recovery

My phone keeps getting stuck on fastboot mode.
I'll flash the standard MIUI ROM using the MiFlash Tool, then I flash a custom recovery and a custom ROM(EvolutionX in this case), everything works and I can set up my phone, but as soon as I reboot I can no longer boot into android or recovery. i've tried flashing multiple recoveries using fastboot and straight up booting a recovery using "fastboot boot recovery.img" but it still always go to fastboot. The only solution is to start the process all over again, and obviously that's just not an option since I can never turn my phone off after that.
Any tips?

I think I got it solved, at least I got it to reboot into Android and TWRP.
I used this guide, but I'll write the steps I took here in case you're having the same issue. I wound up using xiaomi.eu MIUI rom, but it shouldn't matter what you use, I'll assume you're stuck in fastboot.
Do "fastboot flash vendor vendor.img", you get this vendor.img from the fastboot version of the official MIUI ROM, after you decompress the .tar.gz it should be in the "images" folder
Do "fastboot flash recovery twrp.img" then "fastboot boot twrp.img", this should flash twrp as your recovery and then boot into it, for some reason it only worked with the official twrp, not orange fox.
Assuming you got into TWRP you should now flash the latest firmware(I got mine from xiaomifirmwareupdater.com) make sure you download just the firmware not the entire rom, mine was named something like fw_raphael_miui... .zip
Format data (not wipe, format, it's a separate option in TWRP), it should ask you to type yes, so do that.
Flash whatever ROM you want
Hopefully this helps you, I hate finding forum posts marked "solved" but with no instructions. I also tried the "vbmeta_dv_shivsom.img" method some threads mentioned but it didn't work
Here's a pastebin of the guide I used in case the original link goes down
You can get all the files I mentioned from xiaomifirmwareupdater.com and the official TWRP site

Out of all that, the one instruction that solves it is the format data step. This is the magic step required. You always need to do this when flashing over MIUI.
Flashing vendor was totally irrelevant.
This will tell you what you need to do.

Thanks a lot man! I'm having this issue and it is beyond annoying. I've lost so much time with this BS.
Edit: Does not help actually

I just had the same problem with my Lamentablet.
I was trying stuff up and restarted it in fastboot mode and got stuck there.
So, ways to deal with it:
adb reboot recovery
rebooted the tablet in recovery mode. All I had then was to press the power button to activate Reboot. Solved! From now on it boots normally.
Meanwhile I had discovered that by typing
fasboot continue
the tablet would resume, but at the next reboot cycle, power down + up cycle or reboot after a crash, the tablet would reboot into fastboot mode...
And I found this out when it crashed (it's not called a Lamentablet for nothing!).
Luckily I had a PC with Linux around. It didn't have the software installed but drivers were already in the Kernel and installing adb and fastboot was a matter of mere seconds. If I didn't have an easily ready PC at hand, this tablet would have become a brick until plugged in and rebooted...

OMG Thanks dude.... I'm literally working to installing custom rom on redmi 7a from stock rom but I don't know what reason that make my phone always stuck on fastboot when format data, before this was fine.
