Stuck on boot screen! Help!

Hi!
I bought a Desire HD a week ago and today I decided to try one of the custom roms. I rooted it with Visionary+, turned s-off with the one-click tool found in another thread, installed Rom Manager and Clockwork mod and then flashed it with a custom rom from the recovery/boot screen without wiping anything.
The problem is, when I later tried to install another rom, it wouldn't boot, it's stuck on the HTC boot screen. I've tried reflashing it, wiping everything there is to wipe and I even tried RUU but it won't recognize the phone. Can anyone help me how to restore to the normal stock rom?! I can bring up the Clockworkmod recovery menu if I take out the battery and put it back in.
I would be very grateful if someone could help me with this! Consider that I'm a noob though so try to write the instructions as simply as possible

Hi, I'm basically in the same boat (I take it you tried one of the stable CM6 builds?).
Digged through an awful lot of stuff, found something about downgrading clockwork.
Maybe this'll help you, I'm still having trouble.
I've found an older clockwork recovery image, gathered all the SDK bits and pieces, got my USB drivers set up after even more digging - now this:
D:\android-sdk-windows\tools>fastboot boot recovery.img
downloading 'boot.img'... OKAY
booting... FAILED (remote: not allowed)
It's rooted, S-OFF, all that good jazz. Halp. :<

Which version clockwork mod are you using? And what is the ROM you tried to flash?
Sometimes custom ROMs can take 5 minutes to boot...so give it some more time and see if that helps.

seems like your pc is not recognizing your phone. And should not you flash the recovery first and then boot?

I did flash the recovery via Rom Manager, which gave me Clockwork Recovery version 3.0.0.5.
Then I had Rom Manager download CM6, it rebooted the phone, phone gets stuck in HTC splash screen.
According to the thread I linked above, I needed to downgrade Clockwork Recovery, hence flashing 2.5.x.x via command prompt.
The drivers are installed correctly, I'm at least sure of that.
Recovering my previously backed up stock ROM won't get me further than the splash screen either, same with wiping everything that can be wiped before that.

Then use ROM manager to downgrade the CWM to 2.x. You can do it under the option "All recoveries" in ROM manager. People are reporting problems with the latest version of CWM. Check if you get the same if you wipe everything and install another custom ROM.

Can't find a way to even get past the first splash screen - only thing I can properly access is the Bootloader.

Same here. When I boot I just see the initial "HTC" logo, nothing else.
I had Mike's Revolution HD ROM installed and working just fine, and then I tried to install another mod, which got me to this situation.
I have CWM 3.0.0.5 and I have a nandroid backup of the working system from before installing the last mod.
I tried recovering the nandroid, which goes smoothly (including the MD5 validation of the backup) but it still doesn't boot afterwards. I wiped the boot, system and data partitions and tried restoring again - same result.
I assume my next step is to flash a new ROM but unfortunately I don't have any ROMs on my SDCARD, so I need a way to push it there. I tried with fastboot but it doesn't recognize a partition called "sdcard". I believe adb should work while I'm in CWM but it just says "error: device not found".
Any suggestions?

Sorry, no idea which version, but it's the default that comes with Rom Manager. I downloaded Rom Manager yesterday so I guess it's the most recent Clockwork mod.
Left it for 15 minutes, still nothing. I used Android Revolution HD 2.0.11 for the first flash which worked and then when I tried to install Pays-ROM HD Sparta 1.0 I got stuck on the boot screen. I've tried recovering from the previous backup I made on the recovery screen with no result.

Just got mine back alive
Flashed CWM 2.5.1.3 and restored the nandroid with it.
Spending the last few hours searching the forums my best advice is to avoid 3.0.0.5

Went a different approach - finally figured out that you could mount the sdcard via Clockwork Recovery, threw newest CM7 nightly on there and installed it with Clockwork as well.
CHRIST that was a pain in the ass... and I thought downgrading the stock ROM was annoying.

as a rule i have found out cwm3 is for flashing gingerbread and cwm2 is for froyo

Thanks for the advice! It worked for my DHD too Except that I, after flashing ut with CM7, restored it to stock with RUU! Thanks to everyone here who tried to help

Take your battery off, then put it back in. Hold power button and volume down button at the same time. You come to recovery...or alternately you can use adb.

mate you're a STAR. I actually downloaded a recovery image (from post 1315) in the same thread but it kept saying "connecting to device". When I downloaded the recovery image from 1312 and ran "fastboot flash recovery recovery.img" it say's
sending recovery ... OK
writing recover ... OKAY
What do I do next? Just reboot the device?

oh mother looks like I got somewhere. I did a format device and it went into the CWM 2.3.XX screen as below, reloaded Cyanogen 6.1.3 and boom I'm in. Man I though the device was a goner....I'm almost feeling brave enough to install Cyanogen 7.X

So you are happy with your device now?

Well not really, I went back to HTC Sense because Internet Pass Through wasn't available on Cyanogen and now I cannot get the phone to login and create my google account no matter what

the REMOTE NOT ALLOWED error means you only have radio s-off, so you cannot issue fastboot commands to your device.

[Q] Boot loop after stock recovery TWRP

Hi All,
Been having issues with my HTC One X for the past week now and haven't been able to solve it via google or searching this forum, so was hoping one of you kind people can assist a bit.
I do apologise if this issue has already been posted and I missed it, if you can link me I'll be eternally grateful.
Basically, had a few issues annoying me with my HTC so wanted to stick a custom ROM on it. Did some searching about, eventually got a plan together to unlock and root it. All went fine, unlocked it (S-On still) got TWRP recovery on it (Chose this as the ROM I was looking at claimed to be not compatible with CWR) and was booted back into my stock droid.
First thing I did after a successful boot was to go back into recovery and make a full backup (I may have not ticked the Cache and _android.secure)
Played about with the phone again a bit, getting some of the apps back on as it had been wiped, then made a second backup (This one I know I ticked all the boxes for)
Next I tried putting CleanROM on, but could get past the white HTC screen boot loop, after various reflashing the Boot.IMG and clearing cache, so fired up TWRP and restored back to my second backup. All back to normal.
Used the phone as normal for a day or so then I tried flashing another ROM (ViperX) same thing as CleanROM (White HTC screen boot loop) and then went on to try Team Baked's ROM. Managed to get this working successfully, however the ROM was not to my liking and decided to go back to my stock backup. Here's where the issue started.
Now, when restoring the backup the phone boots as far as displaying my background and the status bar at the top, however I cannot pull the status bar down and the ring to unlock the phone with doesn't appear. It sits here for a few second and then reboots. Boot loop.
I've tried clearing cache, restoring various different ways and restoring the boot.img (though I'm not sure I have the right one) but nothing works.
The last variation I tried for restoring involved:
1. Clearing the phone via TWRP (System Restore/Clear Cache/Clear Davik/Clear System/Clear SD Card (heard this can cause issues)/Clearing Android.Secure in that order)
2. Reboot into recovery
3. Repeat step 1 (in case of locked files)
4. Reboot into Recovery
5. full restore (With MD5 check enable)
6. Clear Cache and Dalvik (Tried with just cache, also done Fastboot clear cache in another attempt)
7. Attempt to boot into OS.
As I mentioned earlier, I'm not sure if I have the right boot.IMG for my phone Model/kernal/other, to be honest I'm not entirely sure of the requirements. The details of my phone I've collected so far are:
Getvar version-main (Not sure if this is kernal or what) = 2.17.771.3
hBoot = 1.12.0000
radio = 2.1204.135.20H
CID = H3G_001
Basically, as far as I can tell from the masses of reading I've been doing, I won't be able to update to custom JB for a while so want to get back to my stock ICS and then OTA to JB when my carrier releases their version, then maybe sometime in the future when the ROM specific to my phone has been cracked consider switching to a custom.
on a final note, I've tried flashing both my backups, same result. I've also tried restoring the stock recovery and doing a system recovery with that. It appears to go through the motions (phone with green arrows? Also had the red exclamation mark, but only once of the 3 attempts) then reboots and it's still the same issue.
Thanks for reading through, any advice would be much appreciated. Used to love my phone but now can barely stand to look at it.
Cheers,
Sean

Ok, so I've now downloaded a different boot.img which should be for stock ics and after flashing that, then flashing stock recovery and doing a system restore via bootloader I will 50% of the time get the lock screen and when I unlock it I see the white HTC screen of the initial setup, then it sticks there a while and reboots. It also reboots after left at the lock screen.
To me this seems like it's doing a check or looking for a certain piece of software/file that's missing but is required to finish the start-up process. Anyone any ideas?
Even if someone can point me in the right direction for an RRU for my phone as football's RRU's seem to be the only one that has the one I need but as of 5 days before all this happened the site they're hosted on doesn't allow 500+MB downloads for free members
Cheers,
Sean
**EDIT** Just done a full device wipe then restored only the SYSTEM partition and manually flashed the boot, then when I restarted it sat on the white HTC on the device setup but eventually loaded up, allowed me to complete the device setup and then loaded into the OS. All seemed fine aside from the phone being stuck in turning off airplane mode. Rebooted it to see if that would clear it up and now I'm back to bootloops before the lock screen appears (I just get my background and status bar)

So you have a nandroid backup ! Then do this
Wipe all in recovery and i mean ALL except the sdcard obvious ! system,data,caches,dalvik cache...
Then boot back into fastboot usb mode and flash the boot.img from the nandroid. Taken with TWRP the boot.img is called something like
Emmc.boot.win (or at least similar to this)
You can flash this file with fastboot command
Fastboot flash boot name of the boot.img (.win in this case)
Then enter the recovery and full wipe if you didn't o that already !
Restore the nandroid and boot it up :thumbup:
Should work

Perfect! Thanks so much man, I never even thought to flash the .wim, thought it had to be .img. Just successfully booted fully back into my old system. Hopefully will stay stable the next hour or so but looking good!
Thanks again,
Sean

Yes, the one came with Android_Fastboot_KIT_V12.x

And make sure you flash a 2.17 based ICS rom. You can not run the maximus JB rom on that 1.12 hboot !

I have forget to mention my device still S-ON
Please guide, sorry for troubling.

Download a 2.17 ics Rom and copy it to the phone (mount the sdcard within the recovery as a usb disk)
Take the boot.img file from that rom and copy it to the tool you used to flash it
Then enter the recovery and wipe EVERYTHING except sdcard ofcourse !!! (Cache,dalvik cache, system and data)
Then install the Rom.zip

No problem mate ! :thumbup:

If you're looking for a Rom, I've got hboot 1.12 as well and tried a few ROMs and only ones I got working were:
Team Baked, based on jellybean though still works with 1.12. No Sense though, and a few things weren't to my liking (to name a couple,backlights on buttons didn't work and multitask button was switched back to menu button like in older devices)
SkyDragon, ics ROM with sense. Only had this a short while but appeared to be an exact stock ROM, everything working the way it should, and with a few added extra improvements.
Good luck

Yes.
Copy the boot.img from the backup to your PC (you can mount SD card as USB from TWRP), flash it:
fastboot flash boot boot.img
And restore backup from TWRP.

Yeah, if you follow Mr hofs 1st post on the 1st page he describes all the steps required to restore. Worked perfectly for me

Thanks alot, got it back as it was before.

Need to clear a doubt; will I be able to update my device with the OTA, as my device is unlocked, S-ON & TWRP installed?

I hope so, I'm in the same boat as you. From what I've been reading, it should still be possible as long as you put back the stock recovery and relock the bootloader.
This website offers links to download the stock recovery
http://www.androidauthority.com/one-x-revert-stock-recovery-76854/
As for relocking the bootloader, I think the process is to run this command whilst in Fast Boot USB mode
fastboot oem lock
After it's run there should be a purple "RELOCKED" at the top of your bootloader menu.
Remember to flash the recovery BEFORE you relock the bootloader

You do not have to lock the bootloader, just the stock recovery is needed ....
Stock rom (out of the box stock)
Stock boot.img
Stock recovery
Here is the 2.17 based stock recovery for those who needs it

[Q] can't boot into CM , can't update bootloader

I've been using viperX for about 9 months now, and today i wanted to upgrade to CM 10. so I downloaded the ROM and used ROM Manager (instead of bootloader) and it after CM was installed, it wouldn't boot. the flash screen was the only thing i saw for about 30 minutes.
then i googled for this situation and found out that most times the solution was to install CM via bootloader, so i tried to do so, and again the same thing happened.
next i thought i should update my bootloader. i was using CWM 2.x, i think it was 2.6.. can't really remember (it wasn't updated since around December 2012 when i switched to viperX). anyway, i tried to install TWRP, downloaded the latest version from their site and used the sdk tools that i already had on my computer (i updated it about a month ago) just as the instructions said. i got no error in the cmd, nor on the phone screen. i tried to get into recovery and got stuck on HTC logo.i tried also downloading the latest version of CWM and the result was the same.
now when I'm trying to boot into CM i get stuck on their logo, and when i try to boot into recovery i get stuck on HTC logo..i couldn't do factory reset either.
my phone is HTC one x (bought in Singapore)
HBOOT version is 1.36.0
any ideas where to go from here?
thanks in advance

You're in the wrong forum, this is the HTC One XL/at&t One X forum. I'll ask for this to be moved to the correct device forum for you.

Hi,
I assume your bootloader is unlocked, I had same problem when I originally tried to flash custom rom (soft bricked phone).
Start from scratch and place fastboot folder in root directory of an easily accesible drive (c and place CWM zip file, Version 5.8.4.0 (for one x) in that folder and use CMD prompt to flash CWM again, then boot into CWM recovery and mount phone as USB storage and hopefully you have backed up original software as Nandroid backup (copy to pc so you have a backup copy). From there you can place CM 10 zip file in root directory of phone and install from CWM after doing full wipe, and wipe cache (all through CWM). Youtube has some good videos (Cursed4Eva in particular) on flashing roms. You may also have to flash boot image or you may get stuck in bootloop.
Hope this helps.

[Q] Restore TWRP nandroid from PC

I'm a newbie and I am in trouble. I have a rooted Nexus 7 2013 and I have a TWRP Nandroid backup which I had copied to my WIndows PC.
Now my Nexus 7 crashed and won't go beyond the X on bootup. The Nandroid and Titanium backups are on my windows PC.
How do I restore the Nexus 7 to working status by restoring from the Nandroid backup and data I have copied to the PC?
Please help. Thanks.

Guys, someone please help.
I don't know how to get out of this mess. I'm still stuck on X.
I can power off the Nexus 7 and power to the recovery screen where I find Teamwin's menu.
I restored (several times) the nandroid backups I found on this menu (they were all done after the last reset) but rebooting then just gets me back to the X screen and no further.
I have a good nandroid backup on my PC but no way to get it into the tablet so TWRP can restore from it. Is there a way to transfer a file to or from the tablet when it will not boot completely?
The advanced screen of the Teamwin recovery menu lets me access a file manager. Is there any way I can use it to move files on or off the tablet to "anything" else?
The last time the boot froze on the X screen, I was able to go to the recovery screen with the android on his back and an X and from there to a reset. But this time I cannot get there and the recovery screen gets me to the Teamwin recovery menu. This has a wipe option. Will this reset the Nexus if selected. Will it remove root? I don't want to go through rooting it all over again.
Essentially I just want to do 2 things:
a) extract data from the stuck Nexus 7
b) reset and restore the nandroid backup I have on my pc.
Please help.......

Just choose the wipe option in twrp.
That should allow you to start android.
Then copy your backup from PC to virtual sdcard, reboot to twrp, and restore.
You can copy files while in recovery but it is more involved so I would try this first.

But will it remove the root I worked so hard to get?

If you worked hard to get root on a Nexus device you did something wrong. It should be as simple as unlocking the bootloader (already done), flashing a custom recovery (already done), and flashing the SuperSU ZIP file (this is the only step you'd need to repeat).
That said, doing a factory reset should not remove root. Even if it does, it would be restored when you restored your rooted Nandroid.

Easy for an expert. I'm a newbie. I used the WUGfresh toolkit and it took multiple frustratng attempts and forever for it to finally download the correct adb drivers that would recognize the Nexus 7. Then all went smoothly.
But back to the present. I'm all fine now (till the next time the Nexus 7 crashes on me). For other newbies like me who run into this problem and need simple instructions here is what I did.
The first time this crash with the boot stuck on the X screen happened, going to the recovery screen (Power button + Volume up simultaneously) showed me the android on his back with a red triangle. Pressing power button and briefly volume up gave me the option to reset the tablet without removing root. Because I was traveling and did not have my TWRP backups with me (they were on my laptop 1,000 miles away) this removed all my data and I had to re-install all my apps and everything again.
The second time this happened, the recovery screen took me to the TWRP recovery screen. TWRP recovery had apparently survived the crash. I needed to save my data before reseting the tablet again. By trial and error I discovered that the TWRP menu has under the Advanced Tab a file manager. also discovered that if you connect a flash device to the tablet's usb port the TWRP file manager could read and write to it (!!!) in a folder called usb-otg (but not to my windows laptop). I copied what I wanted to save to the flash drive. Then I used the "wipe" tool to return the tablet to android.
I installed a free app, Recovery Manager, to reinstall TWRP recovery. Copied my previous TWRP nandroid backup to the tablet and restored everything as it was.
Easy as pie if you know how. I hope this helps some other befuddled user.
sfhub and raptir: Do you know what can be done to prevent this from happening again? Could Google Play being conected to in Europe after it was used to being to conected to in the US cause the problem? Both times the crashes happened shortly after I used the tablet in Europe and the the second time after I used it for the first time in the US.

I can't say for sure what is happening in your case, but in my experience getting stuck on X means your user data got corrupted. The cases I've seen fall into 2 categories:
1) faulty EMMC flash memory. Sometimes if you wipe a couple of times the bad blocks get locked out and you don't see the problem anymore. Other times, they keep coming back. In the latter case, return/exchange/rma the unit
2) android crashes (random reboot) and unfinished writes are not completed corrupting the user data. They put in code in the latest ROM to mitigate this so if you think you are suffering from this type of corruption, install the latest ROM if you haven't done so already.

Thank you for the excellent and clear reply. I'll hope the 2 wipes I did may have gotten rid of my bad blocks.
I'll update to the latest stock rom too.
Thank you.

The updating part got me in trouble.......
I accepted the system update and am now running android 4.3 but lost root.
So I went back to the WUGfresh Nexus Root kit. Updated everything, am now on version 1.7.3 of the toolkit, followed all the instructions (uninstalled and re-installed driveers) and got stuck on the same problem I had the first time I tried rooting: the adb : step3 of the full driver test. adb device not found .
I did reboot twice, am using the oem asus cable, etc. What a pain!!
Unfortunately I am dependant on the toolkit because I do not know enough to root manually.
Suggestions? Thanks.

So you're stock 4.3 now? Rooting manually isn't hard bud, setting up the toolkit is harder IMO.
You just need to download and install the Android SDK. Then download a custom recovery .img file, and a SuperSU flashable zip. Put the SuperSu flashable zip on your /sdcard. You'll then boot into the bootloader, open a command prompt and change directories to your Android SDK (Ex. mine is at C:\sdk\platform-tools) and run the command: fastboot flash <name of recovery file>.img
Then reboot into recovery, flash the SuperSU zip, reboot, done. You're rooted. There are plenty of How To's stickied in the General Forums for the N7 here.

Will look into your suggestions later because I am rooted again. It was the adb drivers again. The universal ones just would not work for me. The Samsung signed drivers on the other hand worked smoothly and then the toolkit ran smoothly and I am rooted. But it wiped out my TWRP recovery so I will re-install that next.
Thanks for the help.
About your advice, than you. But as a newbie I need clearer instructions. "download and install the Android SDK". Where? to the pc or the tablet? etc.
I need to learn more so I don't keep getting into these ridiculous binds!

Review the General forum for the N7 2013 here, as there are threads stickied to the top of that forum which has write-ups and video how to's that'll explain it all. I suggest to review those FIRST before you try doing things just so you can get a picture of what's going on. It may seem like a lot, but once you do it, it really is not.
The Android SDK is installed on your computer.

[Q] No OS, phone boots to cmw but won't go any further need help!

So I attempted to root my HTC Desire 816 dual sim. I managed to get it to work following instructions I found from this site. I then went on to try and install Cyanongenmod onto my device, I can't remember where the site was that I was following but I had to, within CMW recovery, wipe data/factory reset, wipe dalvik cashe, format system and format partition.
I did all this then tried to flash this ROM but it said it was the wrong ROM for my device and it said my device was htc_a5dug. which I've had no luck finding anywhere.
Now the phone will only boot into CMW recovery, I can install superSU but any other ROMs I've tried it has aborted automatically, if i restart the system from CMW, it comes up saying there is no root access, root missing /system/xbin/su ( see one of the attached pictures)
I've managed to get it restarted to the bootloader page twice (happens randomly when I select restart to bootloader from CMW) (pictures of bootloader in attatchments showing no OS)
I have a feeling I've totally stuffed my phone when i formatted the system and partition
If anyone has any idea how I can get this fixed I would be so greatful.
PS I'm feeling quite noobish right now

Download cwm backup for your device and restore it in cwm if you don't have your own backup

where do I get a cwm backup from?
[edit] OK I flashed a recovery stock.img file, then I got a red triangle, the phone rebooted and now its stuck on the htc android startup screen and I can't turn the phone off. so Ill have to wait till the battery runs flat.
In the mean time more suggestions and guidance would be super.
