[Q] Need to download a nandroid backup. Got stuck on bootloop, no power button

My nexus one is stuck in a bootloop, the power button is broken and it has a locker bootloader, so i cant flash a update.zip or a custom rom, can't flash or access the amon ra recovery (amon ra was already installed, so i tried to install again and it didnt worked) or even it's original recovery.img.
The only thing i think i can do is to flash a nandroid backup with fastboot, but i don't have one. Can anyone send me one for me to try to fix it?
I dont live in the USA, so there is no way i can send it to HTC to fix it

I think you're a little confused. The reason the recovery didn't flash via fastboot is because your bootloader is locked, it's also the reason why attempting to flash nandroid .img files will also not work. You can either unlock the bootloader or use the PASSIMG method to get into a working system, at which point you can adb reboot recovery to restore your nandroid. There are other ways but I find this to be the quickest and simplest.

Can't do either of those things without a power button.
If you have Amon Ra's recovery installed then you can use ADB to boot into it (adb reboot recovery), or install Quickboot from the Market, and do what you need to.

First thing is to power up your n1 w/o touching the power button.
Here is how:-
The trick is to connect the phone via USB to a power source (a charger or computer) and then to remove and insert the battery successively, after a while (5-10 insertions) the device will get confuse and will start.
Once u power up, proceed to your recovery and do whatever u need to do to recover your bootloop.

Like i said, my nexus is in a bootloop, so i can't install anything from the market, because it won't boot

I already knew how to power it up, the problem is that to access the recovery mod i would need a power button, and my nexus' power button is broken

Sure, here you go. Once completed you can either pull your battery or fastboot reboot to get into the stock ROM. From there, I'm sure you know what to do

Just one more question, will i need the power button for this PASSIMG method? because mine is broken, that's why i can't unlock my bootloader neither. on the bootloader unlock method it says that i need to press the power button to confirm the procedure.

I think with the PASSIMG method you don't need the power button.

PASSIMG method didn't worked. It says:
Hold down the Volume Down button as you power your phone back on.
A screen should appear showing your phone’s system searching for various files. This will take up to 2 minute
When i power on the phone and press volume down, it just boots at fastboot, nothing else happens =\

Vol- should take you to HBOOT? To get to Fastboot you'd have to hold the trackball.

yeah, u're right
I already tried trackball vol up, vol down, nothing happened

Well that's good then. When you get into HBOOT you should see text flash up on the screen that it's checking for the passimg, then it should as you to use a volume button to say yes/no

If you're getting to hboot and nothing is happening, it's probably an error with your file:
Check the file name.
Check that it isn't a zip within a zip.
Make sure you used a shipped image.
Check the md5.

Try with FRG33, I've used it in the past and its worked fine. Also as danger-rat said, make sure it isn't named PASSIMG.zip.zip as Windows usually hides file extensions.

thx, it worked.
But now i can't flash any custom roms, because when i do that it goes into bootloop again and i have to do the PASSIMG method all over again. Can someone help me with that?

Have you rooted?

Yes.
I figured out what was the problem. When i partition my sd card and install a Custom Rom it goes into the bootloop. But when i just install a custom rom it works fine. Never heard of this bug before. How can i fix it?

How are you partitioning?

Well, i tryed using clockwork with a 1024mb EXT, 512mb ad a 5120mb with 32mb of swap. All of them caused the bootloop.

Try no swap.
Also, I would recommend not using CWM 3.x (if u r?)

Nexus 7 Hard Reset

I have read that a hard reset is activated by:
1. Turn off.
2. Hold vol up/vol down/power on
3. Select Recovery using vol buttons and press power button
4. After several minutes, screen with red triangle will appear
5. Hold volume up and press return for menu to make hard reset
All goes well til #4. Here I get blank screen showing "Google" and it never moves into the red triangle picture and just freezes. I have waited over 20 minutes for the boot into recovery menu and nothing happens.
Have I missed a step or is something wrong? If onboard recovery process is broke is there a way to fix it? I would like to have access to hard reset should something dire go wrong.
No I am not rooted nor have I tried to root and have only loaded apps at this point.
Everything else is working fine and this appears to be an excellent device.
Thanks for any advice....

if you stuck on a screen, just hold power plus both volume buttons at the same time. hold it for a few seconds until you see your device reboot. hopefully you good after that. i got stuck on bootloader screen before and did that to get out of it. good luck!

I am stuck on the google logo right after i do recovery mode. i did what you said to get out of the google logo but i tried again to hard reset but it still is stuck on google logo. and i need to hardreset becuase i have forgot my lockscreen password and it is the only way i can get into the tablet.

oh ok. if that hard reset not working, might be better off trying to remember what the password was. you didnt write it down anywhere?
actually theres a way to reset it, or erase all of your data, go into developement section and check out wugfresh root tool kit or the one from Sambra. it will likely require you to unlock but all data n everything will be erased back to how it was out the box. thats your only hope. if you were rooted already, there mightve been a chance. but i think you have to run one of those tool kits to root and unlock. then itll automatically wipe the tablet clean of any previous data.

So the issue is that the tablet is freezing once you click "recovery" from the bootloader menu?
If thats the case - it's a pretty common known issue.
1) Boot into the bootloader
2) Plug the device into a USB port on your computer
3) Click recovery
That should allow you to access the recovery menu.

Same here - anybody got any solutions/suggestions?

I had trouble getting into recovery earlier, so I installed CW Recovery via Fastboot,
http://www.androidauthority.com/nexus-7-clockworkmod-recovery-6-0-1-0-install-103346/
Now it works, before it was just sitting on that Google screen.

Forgot Pin lock
If you set a pin lock on your tablet make sure you remember it!!!
Apparently google or asus can't do anything so you would have to send it back for a replacement tablet.
Google customer service told me they are aware that the hard reset does not work for nexus 7 tablet.
And they might not even fix the known problem.

Plug the device into the computer before you reset it, otherwise the hardware buttons won't work in the bootloader.

I know how you can hard reset it
step 1) install android sdk
step 2) plug tablet into computer
step 3) boot into bootloader
step 4)
Code:
fastboot oem unlock
fastboot oem lock
step 5) enjoy factory reset tablet

Maybe if you unlock and root the tablet, that might work. But on a unrooted or locked tablet the hard reset does not work at all. Gets stuck at the google logo. Pluging it to the computer or without it won't work. Kinda silly isn't it?

You need to have bootloader driver installed. It comes with the SDK - after booting into bootloader, plug the tablet in, wait for Windows to try installing default drivers, then select to find driver manually and navigate to <sdk>\extras\google\usb_driver. After the driver is successfully installed, keys start working again and the tablet boots into recovery successfully.

I also have one of those tablets that doesn't boot into recovery if you choose it from bootloader no matter if you hook it up to computer, don't hook up to computer, stand on your head, put your ankles behind your head, or beg it. It just freezes at the google screen.
So the quoted part, is your solution.

AFAIK, for fastboot to work, bootloader drivers need to be installed.

Fastboot works. But can't enter recovery from the bootloader menu.

Does fastboot reboot recovery work? Lock/unlock erases the device, so if you're trying to do factory reset, perhaps that's all you need?

Ya that works, if I use the os to enter recovery, no problems. Or adb commands to enter recovery, no problems. Just can't boot to recovery from boot loader with the recovery option in the boot loader menu.

Hi willter12,
Can you fix this issue?
I had the same problem, however, my N7 was rooted before. I recognized that my N7 CWR had been removed when rooted (another guy did it).
So, I installed the Toolkit from this and un-lock boot loader, flash back CWR, everyting was very OK to restore to stock. :victory:
Goodluck.

[Q] Stuck on Htc Logo and can not power off

Hi Everyone;
I unlocked my phone for flashing custom rom. After unlocking i reebooted it and was normal. Then i flashed cwm via htc one toolkit. It was successfull as well. Then i go to cwm and made factory reset + wipe cache + dalvik cache. Then i go to install zip from sd card but i could not find my rom file. Thought, it was deleted while unlocking device. Then decided to reboot phone again to copy rom file into the phone and reboot.
But, when i rebooted phone from cwm, it stuck on HTC Logo( Quietly Brilliant screen). Waited sometime, but nothing happened. Then i tried to power off it and boot into bootloader or recovery. I press and hold power button but it does not respond anyhow. When i am holding power button ,back and home buttons are blinking but nothing happens. Almost five minutes i waited as holding down power button but phone does not power off anyhow. i tried all methods like vol down + power, vol up + power and both volume keys + power. But really nothing happens, just blinking back and home buttons. That's all.
I can not simply power off device. :crying:
I also tried boot device via fastboot commands but it says "waiting for device" means computer does not recognize device.
Guys, i need an urgent help. Please...

just keep trying to reboot via holding power or power+vol down. if it doesnt reboot after 30 sec or so let go then try again. if that doesnt work you will have to wait for the battery to die. once you get to bootloader use all in one toolkit to erace cache. then boot to recovery and you rom should be there if not boot back to bootloader and sideload rom

First thank you for your quick reply. Unfortunatelly, power+vol down does not work at all. Maybe i tried 50 times.
Anyhow, after battery die. How can i boot into bootloader. I mean, can phone be charged again in this situation? Also, even if i manage to boot into bootloader or recovery how can i put custom rom file into phone. Actually, i did not use sideload or whatever you mentioned before.
I am serouisly confused now and don't know what to do.
Anyhow, as you said, firlst i need wait to battery die i think. Then i will report back whats happen.
Thank you again btw.

yes your not the first person with this problem. hold power+vol down to get into bootloader. press power button in bootloader to get in fast boot mode. use all in one toolkit to erase cache and side load rom. i recommend all in one toolkit because it automates the process. just select the option then follow on screen steps

Good to hear that i am not the first person That means somehow there is a solution i beleive. Still waiting for battery die. even i had 50 percent battery at the begining but still it holds on I never say again htc battery is bad
I exeprienced that stucking on boot logo several times before with my other htc phones but holding power + vol down/up worked always. This is the first time for me that i faced with power button can not power off device.. Well, ,i hope i wish i can handle out this problem. Definetley with your help.

I am having the same problem and don't know what to do :crying:
Today I just got my One. Unlocked bootloader, rooted, flashed Android Revolution rom. Everything worked fine for a while... I wanted to reinstall the rom because I wanted to change some options in the installer - I did not wipe because it was the same rom (big mistake I guess!!). After making the installation option changes, when it was done it proceeded to reboot but now I am stuck in a white HTC logo boot loop hell... (with the red text at the bottom that says "this build is for development purposes only" etc). Holy crap I never had a phone that I could not remove the battery. I cannot get this back into recovery or ANYTHING, it just keeps looping... computer recognizes it, no problem with drivers or anything it just doesn't stay connected long enough (because of the constant looping) to be able to use the toolkit.
PLEASE any advice?? Can't even shut it down omg. Do I have a $600 brick here? :crying::crying:

Did you read the other posts in this thread? The way you do a "battery pull" on this phone is to HOLD the PWR + VOL DOWN button for ~15seconds. Your capactivie buttons will blink, too. On my device, it took exactly 15seconds to reboot. There have been some reports of some phones that get so stuck that you just have to wait until the battery dies and charge it back up.
Alternatively, if the computer is recongizing it, try to adb reboot recovery to try and get into the recovery.

hi again. this morning my battery finally out. Then i put my phone to the charger and started it in fastboot mode( that is a good new) Then i left it for 20-30 minutes to charge a little bit for flashing custom rom.Then i went to recovery and started adb sideload. Sideload was succesful and finally came to aroma installer of trickdroid. I chose my installation options and started to flash rom but process was frozen on 10 percent. It was saying unmount system, unmount cahce and both of them has notification as "already unmounted". But installation was not going on. Then again i tried to go back fasboot mode again by press and holding power+vol down but unfortunatelly lights are blinking but nothing happens again. I think i need to wait to battery die again.
Isn't it quite weird? Why power+vol down combination does not work for me anytime? So, do i need to wait for battery die in every frozen? Do you have any ideas or comments ?
Do i need to go back to stock first ?
EDIT : Battery was out again and i tried once more. This time installation (trick droid) was successful but it frozen at the end this time. And unfortunatelly i can not restart (power+vol down) it again again Holy crap, i am really pissed off with this problem.

O..K...Finally, i managed to start my phone and now it works... Especially thank you skinsfanbdh for your support.
But still i don't know how to solve button configuration problem. But anyhow i think i won't need quite sometim to use it I hope someone can find a solution for that later.

[CLOSED] Stuck in bootloop - Cant load a recovery

Hello,
I tried to flash Slim ROM on my TMo HTC One and I accidentally soft-bricked it.
First, I unlocked the bootloader, put the zip folder in storage and then went straight for flashing a ROM.
Since then, I am stuck in a bootloop even when I try to run recovery - I flashed TWRP.
Can anoyone help?

yes, this is pretty simple:
You can boot into your bootloader by pressing the power button for a long time and if the display turns off, press the volume down button and hope you jump into your bootloader.. try this out until you manage to get into your bootloader. If this doesn't work, you should hold your phone below a bright light so the sensor recognizes it.. then play around with your power button and volume buttons and you should be able to boot into your bootloader. Then connect your phone to the PC and use this fastbootcommand after you navigated to fastboot on your phone:
Code:
fastboot erase chache
Now you should be able to boot into your recovery..
If it helped, hit the thanksbutton or ask other questions by quoting my post so I get notified and I can answer
If you managed to enter the recovery, say it, I write further instructions... Because if I write it now and the steps above didn't work... I wrote it for no reason and yeah... just say it

ok.. in that case we have to do some other stuff..
Download the TWRP recovery, it's know to work better than CWM at it's current state, you can download the file for your HTC One here:
http://techerrata.com/browse/twrp2/m7 (credits to: http://teamw.in/ thanks for your awesome work!)
Then when you are in the fastboot mode, use this command:
Code:
fastboot flash recovery "C:\pathToYourRecovery\recoveryname.img"

Broken recovery / endless bootloop!

Hello there,
a few days ago i got a lot of problems with my wifi connections, and in a german forum they told me to check if a custom rom could work for me. So i installed the "Minimal ADB and Fastboot" tools to install the cwm and so on. After i flashed the recovery.img, my tablet restarted and now i am stucked in a boot loop.
The big problem is, I am not able to reach the menu for RCK and so on again with VOL- and Power Button. Just restarting and restarting and restarting... i can not connect via adb or fastboot. The only thing i can do is VOL+ and Power, Windows 8 then gives a signal of a connection, but i don't know what to do with this - cause I only have a black screen!
I hope, somebody is able to help me, to solve this issue.
Thanks and Regards
(sry for my bad english)

What version of stock Rom was it on the tablet when you flashed cwm and which version cwm did you flash
We recommended the latest Asus firmware and the latest working recovery is 6.0.4.7

I also had a bootloop before, I think I hold both volume and power to power down. Then wait 5 minutes then vol - and power to get into fastboot

Hey! My version was the official 4.3 Update WW_10_26_1_18.
I wanted to install the Asus Stock Modded Deodexd Rom (10.26.1.18 JB 4.3) for root.
After I used this tutorial droidbasement.com/db-blog/?p=3223 for installing cwm, my device started to begin his loop. I am not able to Use Vol- / power! I also waited for several minutes

What happens if you just keep holding vol- and power without releasing

All you have to do is power and vol +/- then flash back the stock recovery via fastboot.
Then wipe. Then boot in as normal (you will have to re-set up). If wipe does not restore you, grab 10.26.1.18 for your SKU from asus , rename the .zip inside to T4_SDUPATE, place on an microsd, pop it in, enter boot loader and enter RCK. Then it will flash it.
You should fastboot boot to ensure you are ok before permanent flashing, when putting a new recovery on.
Your bootloader must be on 10.26.1.18 to use anything on DB.

The Problem is, i have no fastboot connection anymore! The loop is going and going, vol- / pow does not work! It is still looping the asus logo and that's it!

You have to be fast. When.the screen goes black hold vol +/- (hold them both) and it will enter fastboot when it cycles since I doubt u can fully power off in that state. Leave USB plugged in.

also, reply back with how exactly you flashed recovery (the command). did you do a fastboot flash recovery recovery.img or a fastboot flash boot recovery.img?

that's a good question. I mean, i did exactly what is written in that post from droidbasement.

Then you should have no issue as long as you are on the appropriate boot loader. Hundreds if not thousands of users are using it at this point.
Power and hitting both vol + and - at same time should get it back in to fastboot. Please make sure you time it right.
Good luck.

Correct. There is no wheelie/nvflash/bricksafe for this tablet.
You need to provide more information how you got into this situation.
Can you boot into fastboot?

And after the second reboot got endless bootloop(((
Exit from it turns out only by pressing vol+
I apologize for Google translator

Asus help is needed
Hello ASUS !!!
You have to HELP us, in order to keep your consumer with you. Other vice people will start to think that your ASUS brand is not a trustful brand anymore. Using such tricks as providing consumer with possibility to open a "Pandora's box" with bootloader unlock, and after you pushing consumer to pay about 300 $ for "motherboard replacing".
Following such kind of policy you will collect some money but definitely you will loose much more.
Sincerely,
Stream1313
PS: I was started to use the "unlock" etc not because I do not have other business t do but because of the serious problem in your DEFAULT STOCK software.
To: Moderator - please do not delete this post, hopefully some ASUS people will read it.

I have the same problem after trying to install OTA from SDcard and then erasing data from power+(vol-)-menu. It's looping all the time and I've tried everything. Only APX works if I use naked drivers (transformer APX-drivers).

You cannot get into fastboot?
How about ADB while it is looping?
You will have to provide more info: What do you have installed?
Bootloader version
ROM
Recovery
What exactly did you do?
APX is useless at this point as there is no way use nvflash on the Tegra4 yet.

no, no chance to get into fastboot or using adb. the only thing that works is APX after pressing volume+ for about 10sec.
what did I do: I tried to install clockworkmod recovery and flashed recovery.img from fastboot. Then I restarted my device. I was sure I did every OTA-update because I checked almost every day for new updates. BUT starting up the tablet I saw my bootloader wasn't 10.26.1.18 (required for CWM). So I went to ASUS-website and downloaded WW_epaduser_10_26_1_18_UpdateLauncher and tried to update. But this did not work. So I rebooted pressing power and volume- ... then wiped data or whatever the third option was ... after that my looping started.
I've copied T4_SDUPDATE to my microSD and tried almost everything... charging, apx and looping is the only things that work at this moment

Sorry mate, but you hardbricked your tablet.
You installed a recovery that is incompatible with your bootloader, which is not good but fixable.
Then you used 'Wipe Data' from the bootloader which is pretty much a recipe for disaster with an incompatible recovery installed.
With no fastboot or adb access there is no way to get it back.

so nothing I could do over APX, microSD and the 3 buttons? no chance, even in future?
