[GT-i9020T] Stuck on Google screen - Nexus S Q&A, Help & Troubleshooting

I know there are plenty of these threads, especially this one:
http://forum.xda-developers.com/showthread.php?t=1093316
but right now, I'm stuck, and really confused as to what I am doing. In fact, maybe I should not root my phone at all in the first place so I would appreciate if you guys can help me return to the stock 2.3.4 on i9020T.
The thing I don't get is the "Flash the latest cwm recovery". I'm not knowledgeable on any of this stuff (which is why I'm just gonna stop what I'm doing).
I went through the instructions on this thread:
http://forum.xda-developers.com/showthread.php?t=895545
as well as:
http://nexusshacks.com/nexus-s-hacks/how-to-root-nexus-s/
The recovery-clockwork renaming part did not work for me on the first thread, so I decided to follow the 2nd thread...after unlocking the thing (by typing fastboot oem unlock), I typed in "fastboot flash boot rootboot.img"
It says it went successfully...but that just caused everything to be stuck on Google screen with a padlock unlocked...
Then I went back to cmd, typed in fastboot oem lock.....it locked...but it's not helping my situation.
Right now, I just want the phone to be working just normally without any rooting.
In case this is important, I'm from Canada on the Mobilicity network
**UPDATE**
I disconnected the USB, powered it on normally...Google appears, then disappears, the buttons on the bottom just lights up and I get a black screen.
Once I connected back the USB, powered it on, Google stays on, button lights stay
I would like to thank all of you in advance if you could help me out here =(

Going back to this thread: http://forum.xda-developers.com/showthread.php?t=895545
I managed to get into ClockworkMod Recovery...finally got into the sd card storage, dragged the file shown on this thread: http://forum.xda-developers.com/showthread.php?t=1093316
installed.................OMG THE NEXUS BOOTSCREEN IS BACK!

How to know if your magic is truly bricked or only semi bricked.

I've had the great misfortune of bricking my phone within the first few hours of owning it. I should have known something was up, it wouldn't reboot when I changed the language to English, and I'd have to hard reset it (delete everything) and then let it load in Chinese again. Well, in an attempt to fix what I thought was a rom issue, I went through the song and dance of trying to root my phone.
I'm still not fully clear on how to do it, as it seems there's more to it than just what the tutorials say.
Anyway, like the title of this thread says, there's a pretty good way to figure out if your phone is really bricked, no need to ask or wonder anymore.
If your phone only boots to the htc magic screen (and then stops), and is unable to load bootloader, fastboot, usb connections, or anything else, it's bricked. 100%. You have to take it back. Don't bother searching the forums for the answer, I've wasted hours going through every related thread and trying every possible solution. Without the ability to access the fastboot screen, you're out of possibilities. Untill someone comes out with an unbricker which goes deeper than fastboot, there is absolutely no way to fix it.
A semi brick is much better on the other hand. There are plenty of ways to fix your phone, provided you're only semi bricked. I would define semi bricked as being able to enter fastboot, but being unable to boot the phone as normal. This can happen with a bad flash, or a mis step during a tutorial. I'm not exactly sure how easy it is to change a semi brick to a full brick, but my full bricking happened after semi bricking it while loading a new rom on it.
So. to summarize, if your phone WON'T go into the boot menu by pressing vol-down+power, you're in need of a new phone.
If you can still get into the boot menu, and access your phone through usb, you're ok, just get help (via a tutorial) before going any further, unless you're completely certain of what to do next.
Tis a shame to send a device, which is physically undamaged, to the digital graveyard. But such is life.
Caid.

EDIT
on a side note, before my phone reset itself into it's endless loop of unloading, I noticed the screen flash an image of a box with what looked like a red arrow coming out of it. It was right in the center of the screen. This was in the recovery-RAv1.0H.img menu. What's that all about?
Did you try other key combinations such as Home+Power, or Back+Power?
I'm sorry but I think you're misunderstanding it all a little bit...

Wrong. If your phone boots to the HTC Magic screen, the bootloader is doing it's job. The bootloader just takes you there. The linux kernel and ramdisk takes you to the boot animation, and there is where android really starts.
If your phone shows the first htc logo, or the Vodafone branded screen, you can start in bootloader mode. To make that you just have to remove the battery, put it back, and press and hold BACK + END KEY. From that, you can fastboot.
Also, and unless you destroyed the recovery partition, you can also boot in recovery mode, by pressing END KEY while holding HOME (no need to keep them both hold, just home button)

I would call a semi brick this:
Your phone goes into an endless loop while booting.
Your phone gets stucked on the first boot logo.
You can't get access to the recovery partition.
Your phone boots all the way but then gets stucked.
Your phone gone bad during a software update.
That, all, can be solved by reflashing the affected region. There are tutorials for everything but if you need I can write some hints on each case (I suffered them all ).

Actually, VOLDOWN+POWER starts in Hboot mode. From there you can go back to fastboot mode, but hboot is used to make a software upgrade using complete images or running htc diagnostic images (SAPPDIAG.IMG, SAPP*.IMG /NBH).

If you can't get USB working on fastboot mode, or on recovery mode, your phone has probably a hardware fault. It happened with some of the first revisions of the Vodafone branded magic, don't know about htc branded ones though..
NOTE: Not talking about missing drivers, if you don't have drivers, that's another problem, but the computer should at least detect the device. Also, if your phone is off, and you connect the charger (or usb) and the orange led lights up, the bootloader should be ok.

That's the recovery mode. With that you can unbrick your phone
Also, as another hint, if you're new to linux OSes, you might want to take a look at some manual on terminal commands. If your main software is bricked, it's possible that your SDCard doesn't get mounted on recovery mode, depending on wich recovery image you're running. Provided you have an update.zip on the sdcard you need to run, you might have to mount it manually.
To do that, you have to start the phone in recovery mode, and run an "adb shell" on the PC.
When you have a shell opened, you'll have to mount the sdcard manually:
mount /dev/block/mmcblk0p1 /sdcard
Then, on the phone you can use the option to run sdcard update.zip to restart the software upgrade procedure.
Regards!
Before I reply, I'd just like to say thank you very much for your extremely in depth reply.

To the first answer.
It's not THAT easy, the guides are kinda (you should already know what you're doing at this point) in nature. It's confusing for newcomers, as we've no idea what to expect, that and there are a multitude of variations. More specification as to which guide works with which model, and which updates would be nice.
As for the second part, I could not get the phone working with any button variation pressed. I'm sorry I was not more clear in my description, to begin with. I could press (and hold) any button (or buttons) + power (end key) and the phone would just vibrate (briefly) and then display the original screen "htc magic"(endlessly). The orange light does come on when plugged into the usb or computer, but only while it is off, as soon as the device turns on, the light turns off.
Another thing of note is that, after bricking it, I had to remove the battery to turn it off (every time if it was on), and if I put the battery back in while it's plugged into the usb port of the computer, the phone would turn back on without pressing any buttons. It's also completely unresponsive or detectable by my computer after bricking it. The only other thing I can get it to do is make the orange light blue by holding the action button and turning on the device. That way the light on top of the device is blue when it turns on. Still unresponsive at that point.
This is my first android device, but not my first htc device (I've had MANY MANY different ones.) so I'm a bit familiar with trying different combinations to get a response.
I am not the first person who's had this happen, unfortunately. There have been a couple others, who've described the exact same encounter. Perhaps it's a mistake that I made, and perhaps they also made it themselves. I would like to figure out how it's happening, though, and perhaps write a tutorial for people like us unlucky few.
Again, a really big thanks. I've sent my phone back and am getting a new one soon. I much appreciate your reply, however, as it's probably the most understanding and considerate reply I've seen on these forums.
Cheers.
Caid.

One more quick question out of curiosity, when you press and hold back and press end to turn on the device (it still goes to the htc magic screen) SHOULD it go to a different screen, other than the "htc magic" screen? Or is that a process that runs without some sort of visual notification on the device itself?
The usb was completely unresponsive after this happened, but in the event that bootloader may have been running, (only possible if it runs without any visual notification on the device itself), I'll go pick up the device and see if my usb drivers on my computer just became unresponsive after being accessed too many times. Sometimes windows does that, right? Perhaps a reboot would have allowed fastboot and the drivers to connect again, if the device was trying to talk to the computer, but I just didn't know on account of not having any notification.
So, again, should pressing back and power bring me to a different screen? or would it also look like it was hanging on htc magic screen?
Caid.

p.s. Sorry for the confusing wording, I'm tired and trying very hard to be as specific as possible.
back+end/power should lead you to the fastboot screen right after it shows the HTC Magic screen or whatever splash screen you have installed.
Home+end/power should lead you to the recovery screen.
ok, it was bricked. Thanks for the answer.

No problem, we all should be here to learn, and to help (except for the trolls)
This is the guide I followed for both Vodafone branded Magics: http://android-dls.com/wiki/index.php?title=Magic_Rooting
Maybe not for now, but for the next magic you get it may come handy

When the phone is off with the charger connected and you press the power button, the light goes off, as for the others, you really should be able to enter the SPL if it could the magic bootlogo and vibrated upon boot...
Maybe you didn't try enough or maybe your bootloader behaved differently than mine... I should be more clear anyway, to get to the bootloader, the best way to make it go to the bootloader is press and hold back key, then while holding it, hold the power button too. It should take about a second or two before showing the three skater droids.

When you put the battery while USB or charger is connected, the phone boots up, that's the normal behaviour. About the blue led, that's the Radio bootloader. That's quite dangerous to play with, but it gives a lot of other functions. Another sign that your phone wasn't completely dead Even if you wipe the SPL (the three skater droids), you may be able to boot into the Radio bootloader and write or boot another one to fix it. But that's waaaay harder

I guess the first advice when you start tricking with a phone is be careful with what you're doing. That's the good thing of fastboot.
When booting on fastboot mode, you can pick, for example a recovery image, and boot it without overwriting the original rom:
Code:
fastboot boot [recovery_image]
Then, when you see it's working, you can flash it:
Code:
fastboot flash recovery [recovery_image]
fastboot flash boot [boot_image]
fastboot flash system [system_image]
fastboot flash data [data_image]
You can't do that with the system.img since it's too big, but you can do it also with a boot.img
About the key combinations on the phone, it goes like this:
Code:
BACK + END KEY -> Fastboot mode (you shouldn't see the boot logo)
VOLDOWN + END KEY -> Hboot mode (you shouldn't see the boot logo)
ACTION (trackball center) + END KEY -> Radio Bootloader (you shouldn't see the boot logo)
HOME + END KEY -> Recovery mode (you should see the boot logo, then get the recovery menu)
SEND + MENU + END -> Reboot the phone (while the phone is on)
Maybe there are more (android has kind of 'safe mode' but I don't know it it goes there automatically if there's a problem or if it has to be called manually)
Anyway, I hope these things will be useful for the next phone, and for anybody who's a bit lost on this
Regards!
Let us know where you live , so maybe one can help you , I live in Sweden and will be glad to help you if you are near ;-)
Hey! Thanks again for all the help, and the offer to come help. Unfortunately, I'm in China. Coming here from Sweden (although it's a single large landmass) would take quite a bit of time
I appreciate all the support, though. Very cool community we're building here for the magic.

htc semi-brick?
Hi to all. I'm in the same condition described in this tread; after installing SPL i get the htc block in Vodafone brand red screen.
None keys combination bring me to the boot menù. Only Action(trackball) + power have effect, but with a black screen...
Any suggest?
What do you do if you can boot into fastboot but can't flash anything because absolutely everything gives the error "FAILED (remote: signature verify fail)"?
I have a card reader and have tried just about every sappimg.zip, every boot.img, every recovery.img i could find. I can't even boot a recovery img because the screen just hangs at the HTC Magic logo.
I don't know what kind of warranty i have on this thing, but i might take it in tomorrow and see if i can get it replaced. I've only had it for just under two weeks.
Newbie need help
ok so i can still go to recovery mode but everytime i reboot my phone the mytouch 3g logo never goes away im new to Android but not htc can somebody plz help me out.

Instead of flashing something, you boot a recovery image, and then, from there, you flash whatever you need (using adb & flash_image for example)
PS: Be a little patient, if fastboot is letting you boot a recovery image, the recovery needs to boot, and that takes a little while, and while it's booting, you see the bootlogo until the menu appears. Also, you can try running adb shell after boot process started to try to get an error message (or at least to know if the thing is booting in some way)
I couldn't boot any recovery images. I had tried a few different Hero ROMs but decided i wanted to use Cupcake again because i have a 32B board and it just doesn't have enough RAM, though Swapper makes it usable at least. I don't know what exactly i did, but i've learned a lot from my mistakes. Everything i tried failed the signature check because the hboot version didn't match. If i could just flash the 1.33.2005 hboot again, i would have been in business, but no matter which recovery image i tried, it just sat there doing nothing. And believe me, i waited.
Fortunately, T-Mobile gave me a new device after i took it in and played dumb. And I just rooted it =]

Why not flashing it with an RUU from HTC. Not sure that would work but it is worth trying.
Hi there, people!
First of all, thanks because while I was reading ur posts I realized that my phone had been bricked, 100 %
I tried official ROM upgrade to Android 1.6 using the folowing steps
1. Copied radio zip to my sd card by renaming it in update.zip
2. Recovery screen was started by pressing HOME+END key
3.Applied update.zip, process was going on: Opening package, verifing package, installing radio...and message about success was shown and phone restarted
4. Phone stucked on HTC Magic logo screen...15 minutes
5. I removed a battery, put it back and tried to reach recovery or boot mode again
6.Unsuccessfully! Phone vibrates and turns on...but always stucks on the HTC Magic screen
7. USB does not recognize my phone is connected (I tried any adb and fastboot commands)
8. So, I just pray to give me a new phone if my warranty will be accepted

I have the same problem. I get up hboot and fast boot menus can not get it in recovery. try to add in sappimg but no luck
I'm having the exact same problem...
Any solution yet?
Hello! I can assure you that your phone is not fully bricked! Awhile ago I flashed a new radio only to discover that I hadn't done my research and was a complete and total idiot. I flashed the 1.76.xxxx on a 32B. It didn't like it. I got a quick HTC logo that disappeared then the phone never responded again. When I say never responded it was dead. no combination of buttons would get any response. If you can get into fastboot you have options. All that's necessary is to make sure you have the appropriate sappimg file. Try the Unlockr's gold card method file. He has a .zip file that may work for you. Just make sure that you find an image that is compatible with your board (32A or 32B). Hope this helps!

Trying to root my g-slate

So I got bored with waiting around for someone else to do it, and decided to take a shot at rooting my G-Slate. I figure it's basically the same as the Xoom, so the same sort of process should work....
My initial game plan was this:
Get into Fastboot
Flash a recovery image
Boot the recovery image
Now "adb shell" is a root shell
Copy a "su" binary into /system/bin
Declare victory
That started out pretty well. Powering on and holding down volume-up gets into fastboot. The fastboot binary on my laptop sees the device. Typing "fastboot oem unlock" claims to work. Flashing the Xoom recovery image [1] claims to work.
But... I can't seem to boot to recovery. Running "adb reboot recovery" just reboots normally. Doing "fastboot boot recovery.img" freezes the device. Booting with down-volume gets me to some sort of LG updater state that might as well be freezing the device. Booting with both volume buttons down either 1.) doesn't boot or 2.) brings me to fastboot. That's all the button combinations.
So I guess my question is this: does anyone have any suggestions for how to proceed?
I really don't want to just blind-flash the Xoom boot.img from the unlock thread, because if that doesn't work my device is bricked until someone either makes a working kernel or somehow extracts the current one.
On the up side, my g-slate is *claiming* to have working fastboot that can flash images. It could be totally lying though.
[1] http://forum.xda-developers.com/showthread.php?t=1038870
Tried the same method. No dice. Right now there has been no luck on anyone's part that i know when it comes to rooting. Shoot we havent even been able to get one of the xda mods to create us our own forum for that matter...i had to go out and create my own. I have tried other methods that worked on my nexus one when none other would but alas still no luck.
I imagine since the g-slate is brand new that its not a question of if it can be rooted, but how and when. I'm going to try one more method i know of that worked on the lg optimus tonight. I'll post here if it works.
Soure code seems to be available too
It also appears the source code is available from LG here .lg.com/global/support/opensource/opensource-detail.jsp
I just did a search under mobile phones for the model number 909
Don't know if that will help anyone here.
I have been hunting all over for root access. fastboot says I unlocked the bootloader but nothing seems to want to take.
XDA Mods, please create a G-Slate Section
HA. member since 2006 and my first post just add a www in front of that link
When the fastboot says Ok it is not telling you that you have unlocked the device. It says ok no matter what you put in. Try unlock and it will say ok as well. If it unlocked the device then it would prompt you on your device with a popup that tells you that you are voiding your warranty and have you hit ok. The device is not unlockable using the 'fastboot oem unlock' command. I have rooted a lot of devices, but never have done anything on an LG device and it is awkward. Vol+ and power gets some form of fastboot. Vol- and power gets download mode, which I am used to from Samsung devices (if we can get an interface like Odin then this becomes a lifesaver and makes the device "virtually" unbrickable). I cannot find any form of recovery. 'Adb reboot recovery' just restarts the device. One interesting this is that pushing both Vol+ and Vol- and power puts the device into what would seem like a bricked device (just use reset button). This same button combination worked on some Samsung devices so something is happening there, but I have not tried enough combos yet to figure it out.
So far as root, well, I have tried z4 (works with nearly all Sammy devices and LG seems to be using a lot of Sammy ideas or at least it looks that way), but to no avail. Gingerbreak apk might work or even the Xoom Root, but the rootboot.img might be different and I have not opened any of that up yet. I did get SU loaded once and in the system, but I could not reproduce it.
I will be working on this some more this weekend (returning the device at some point as it reboots on its own about 5 times a day), and looking into the recovery issue. If anyone has any ideas then please post.
Also, it looks like LG hacked the crap out of the thing to get the SD card to mount and it is weird, so please be aware of that. The SD card mounts every time you plug the device in and there is no way to turn that off. The reason this is important is that some root methods require that the SD card not be mounted, so you will have to unmount the SD card via ADB and with the card being internal I am not too sure it is a good idea, but . . .
I will mark this thread as a favorite and update if I get any where. I know that Cyanogen and Kmobs got G-Slate's recently, so hopefully they can give us a little insight once the device gets to them. I have also contacted LG and @TheLGGirl and asked them to confirm that the bootloader is locked, but have not heard anything back.
Also, the the Acer HC tablet was rooted yesterday using the Gingerbreak root method, and so that is helpful, but it has an SD card (see above).

I tried the Acer method (GingerBreak) and it does not work. Will look at the logcat in a bit.

Thanks hourst
I am used to odin (also have a vibrant). Something like that would be a life saver.
Makes sense about the fastboot commands seeming to take.
I was also having reboot issues with mine. I had a handful of reboots each day (about 3 or 4) for the first two days but they have stopped completely now. I have had it for about a week now and have not noticed a reboot since day 2.
I will keep poking around to see if i can come up with anything as well.
Could this help?
Under the impression the G2x root method maybe helpful since they are both LG devices with somewhat similar hardware.
Does anyone know or tried this http://forum.xda-developers.com/showthread.php?t=1056847 to see if it works?
Not sure if I am brave enough yet. But it could be possible the vol up+vol down+power button combo that seems to lock the device is putting it into the mode needed to run the nvflash application.
This really is mostly speculation but could be something to try.
Success
So i got brave.
vol up+vol down+power Device seems to freeze. Plugged in the usb and got a new hardware pop in windows. Listed it as APX device using the drivers in the file listed in my previous link installed successful and the device was found.
That is a far as I went.
im doing the NVFLASH right now... wish me luck and see how far I can go
Any Luck?
Suzannemscott
How did it go? any results or do you have a large brick?
ok i tried. and no luck , i did manage to brick it tho, but i was able to unbrick it phew, back to square one
Did it seem like anything happened? Also what did you do to unbrick it?
To unbrick it i just press the reset button, in the back, quickly hold down Vol+ and Vol- then it goes to a the Gslate screen with the square and then i hold down the reset again and it reboots, maybe i am doin to much but hey it get my Tab back it works!
Gah! Why does it claim to have fastboot when *any* fastboot command except "fastboot devices" just makes it freeze?
I went ahead and built the kernel that LG released and packed it into the clockwork recovery image for the Xoom. Fastboot boot... freeze.
Computer always says this, but I think it's just making fun of me:
downloading 'boot.img'... OKAY
booting... OKAY
I also tried to build and boot a custom kernel with a fb console enabled just to get some feedback, but all it wants to do in response to "fastboot boot" is freeze.
I'm starting to get discouraged here. My 14 day return period ends on Tuesday and I don't really want to get stuck with an unrootable device.
Chandon, would you be able to send me the kernel you built?
I'm sure someone with more expertise and knowledge will be able to root this thing eventually...but right now it seems to be a lot trickier to root than I initially thought. It's not unrootable...just complicated. Over my head by a lot. I don't think I'm going to return it...but I've now resigned to the fact that I may not ever be able to find a working method to root the damn thing myself.
SmellyTunic -
I've uploaded the two kernels I built [1].
They're both built from the v909 kernel source posted by LG[2], following the instructions posted by adrynalyne[3] for building custom android kernels, but I don't have any way to test them aside from the fact that "fastboot boot" doesn't work either straight, with a ramdisk, or with a rebuilt recovery image using the tools in [4].

When the fastboot says Ok it is not telling you that you have unlocked the device. It says ok no matter what you put in. Try unlock and it will say ok as well. If it unlocked the device then it would prompt you on your device with a popup that tells you that you are voiding your warranty and have you hit ok. The device is not unlockable using the 'fastboot oem unlock' command.

Not entirely true. You said that if you try simply typing in "fastboot unlock", it tells you "OK" as well, right?
Not for me. That only ended up displaying the whole list of fastboot commands.
I agree with you that "fastboot oem unlock" is not unlocking the device though. But what are the alternatives? Everything I've ever rooted has used "oem unlock". I've never even heard of a different command that can be used to unlock a bootloader. I tried a google search and came up with nada.
Hmm...

Nexus S not booting up

Hi
I got somehow a big problem.
I tried to update my Nexus S by mistake with the I9020A 2.3.6 Rom. It failed. At least somehow it said so.
Now i cannot load my phone normally. Sometimes I have to battery pull several times before the Nexus S boots up again. The other times it stays with a nasty "Google" on screen.
Even more strange. I cannot access the recovery submenu. It does stay at the same nasty "Google" on screen. It does no longer show up the triangle where you the can load an update.zip
What can I do?
Nexus S: GT-I9020
I9020XXXKB1

Thanks for help
Cheers

Since you said you can't access the recovery console and it gives you a google logo, I'm going to have to ask: Do you have access to the fastboot bootloader?
If so, are you rooted? If no, you have the option to take it in to get fixed or to root your phone.
If you decided to root/are already rooted, connect your phone to your computer while in fastboot, make sure all drivers are installed and use a command prompt to use the fastboot tools. The Unlockr's Nexus S rooting guide will be a huge help in guiding you where to be.
Does "fastboot devices" return anything on your computer, or is it empty?
(Sorry if you know most of this crap, but number of posts + lack of information in the OP + you saying you don't have a custom recovery = assuming you need a bot more in depth instruction.)
Thanks god I have been able to push the fastboot recovery console!
I did manage to access backup & restore and then load the stock 2.3.3 rom. I am back in business
Thanks for help. I think it is solved.
Cheers
Martin
Now make sure to make a backup.... helps save your a$$

HTC Desire S hangs on carrier logo :-(

Dear forum,
I kind of hesitated to start a thread for my problem, but after a long time I still haven't found a solution. I have contacted HTC (no answer yet), but hope to resolve my problem in meanwhile instead of waiting 1 month+ for a replacement.
I got the -by now familiar- freeze, and after rebooting it would go beyond the HTC logo, then stay stuck in a backlit black screen mode. Tried removing the battery, sim card, sd card etc. Then decided to boot into recovery (vol down + power) which worked, but any option would freeze the phone, like factory reset which I tried first.
Right now, the phone already freezes at the carrier logo, and I can't even get into recovery again (vol down + power). The phone won't respond to the key presses, and eventially boot and freeze at the carrier logo. The weird thing is that before, after a lot of trying and re-inserting the battery, it would eventually boot and work just fine for about 1 in 10 tries.
Does anyone have any ideas what I could try? Any help would be greatly appreciated!
edit: Okay, after a while I finally managed to get into HBoot again! Now what should I do to get my phone resetted/fixed? I guess it's not possible for me to flash another ROM or something as i'm not rooted. Details shown are: S-OFF, HBOOT 98.0002
can you get into recovery from bootloader?
Seems like I now consistently can boot into HBOOT. When I choose recovery, it will reboot, show the carrier logo, show the green logo with circular arrows, and then switch to the phone logo with a red exclamation mark for two seconds. Then, it shuts off. Also, when I tried that just now, it buzzed for like 6 times very fast after turning off.
On the second try, exactly the same happened: red exclamation mark, screen off, +- 6 fast buzzes.
After doing that, it doesn't respond to vol down+power or power at all. After reinserting the battery, I can get back into HBOOT
edit: it didn't want to boot into HBOOT, but now it does again. Anyhow, chosing recovery is still green logo, red logo, screen off and some buzzes. The phone doesn't show up in "adb devices" neither.
Whatever you are going to do; do not root your device as it will void your warrenty.
Is there anything else i can try doing? The situation so far:
-normal boot just stays stuck into carrier logo
-hboot->recovery gives a reboot, green logo, switch to red logo, screen off and +- 6 fast buzzes, then nothing. Needs battery reinsertion to be able to respond to vol down + power again
-hboot->factory reset just freezes on the same screen, no response, needs battery removal
-noshow in adb devices (update: show in fastboot!)
Another update: after messing arround with the drivers which didn't seem properly installed, I know have my device showing up in "fastboot devices".
Please, I feel like I'm so close to fixing this. What could I do next? Fastboot in some different recovery with more options or something? Anyone?
Could I simply run the RUU for my 3UK branded phone now?? If I get the RUU from http://forum.xda-developers.com/showthread.php?t=1002506, it seems that the RUU is "signed", which would result in S-ON? While right now my phone is S-OFF?
edit: So, I ran the proper RUU, it will find my device, propose me to downgrade from 1.47 something to 1.37 or so. Click next. Then it stays on the "rebooting the bootloader" phase indefinitely

Slow down maxxur, wait for this quesstion to be out there for long enough for someone to answer it.
Dont go on a battery pulling spree, coz that is the first and most tempting response on a frozen phone. But i hope you know what that can do to this phone...
Give the xda community some time to figure this out. Hold your ground till then. Need to go in to the theatre now. Will get back in the evening and try to figure this out.
Try running the RUU while in the fastboot menu (usb mode). Also my suggestion is not to make the process more complicated by downgrading - just reflash 1.47...
Thanks for the response guys
The RUU I found was 1.37. Could you point me to a 1.47 RUU for the 3UK network?
Also, running that RUU when in Fastboot USB mode is what I tried. The info on the RUU shows that it hangs indefinitely at "rebooting bootloader". That is expected, as when I try to manually reboot bootloader in my fastboot menu, my phone will also freeze.
I'm wondering if running a different recovery image could be of any help? Last night I tried running CWM recovery to see my options, by entering "fastboot boot recovery.img" but i'd get a "remote: not allow" error.
Have not noticed that you are not rooted!
Why don't you try the revolutionary tool? If you have luck it will restore your bootloader if it is broken (keep in mind that is not the best option because it will break you warranty). Then you will just need to flash an eng hboot and run the RUU, or better try some custom ROM
But in my opinion the best option for you is to go for a replacement rather to try yourself, since you dont have any custom software on it it has to be covered by your warranty (probably it is a faulty device to go like this from nothing).
Thanks for the suggestion. Are there any other safer options for me?
Could I try extracting the rom.zip from the RUU and manually put it on the SD card, then try to flash it in CWM recovery? Since "fastboot boot recovery" doesn't work though, could I try "fastboot flash recovery" to get CWM on there? Atm the "stock recovery" seems to be dead anyway, as when I choose it in HBOOT, the phone simply freezes.

Of course you can if you are eager to try this. When you run the RUU, even when there is no phone connected there is a folder in your C: drive created (I assume that you are using Windows). Open your Windows Explorer and search for the rom.zip. When you have it copy it somewhere and close the RUU screen. Then if you open the RUU all the *.img files are there. You can try flashing the stock recovery or hboot or whatewer using the fastboot command. But I have to say again the best option for you is to bring the phone for a repair before you end up with something irreversible and void your warranty.
Thanks for keeping me sane on what to do with my problem Mentally, I came to the point where I'd go flash CWM recovery on my phone and try to flash that RUU rom from there, but you helped me get around that thought and now I made arrangements for HTC to come and pick it up. I'll keep you guys posted!
PS: you've got to love our desire s community, it's the best.
Cheered too early
Now HTC suddenly responds that while entering my phone in their warranty service thingy and the phone seemed to be 3G UK branded, they told me they "can't" do repairs for those.
Seriously, HTC is trying to troll me saying the inner hardware could differ between a UK and a Belgian Desire S?? Could this be true in any way?? :/
Maybe some parts are cheaper but with the same parameters...but I thought that when you have a branded phone you should seek your warrancy support from the carrier's office?!?

Options for solution!
Option 1: Copy rom.zip (from RUU_Saga_HTC_Europe_1.47.401.4_Radio_20.28I.30.085AU_3805.06.02.03_M_release_199410_signed) to your sd rename it to PG88IMG.zip and let m boot into hboot.
If option 1 is not ok try option 2.
Option 2: Boot in to fastboot connect it to your computer and on your computer open dos/terminal run fastboot oem rebootRUU then after that run ruu RUU_Saga_HTC_Europe_1.47.401.4_Radio_20.28I.30.085AU_3805.06.02.03_M_release_199410_signed.
If option 2 not OK then there is option 3.
Option 3: Boot in to fastboot connect it to your computer and on your computer open dos/terminal run fastboot oem rebootRUU after that run in dos/terminal fastboot flash zip rom.zip (extracted from RUU_Saga_HTC_Europe_1.47.401.4_Radio_20.28I.30.085AU_3805.06.02.03_M_release_199410_signed)
Let me know if one of these option worked for you if not I can help you with reflashing your hboot again.
NikMel,
Thank you so much for the tips. Currently I'm trying the first HBOOT + .ZIP method. It detected it, asked me to update and is now showing a pink "Updating" sign. How long should this normally take? I have a strong feeling it simply froze again, and it really turns out to be a hardware problem.
Is that updating next to radio?
If yes it will take realy long so wait!!

[Q] Nexus 5 stuck on google logo boot loop

Hello everybody here at XDA, ( this is my first post here so bare with me here)(english is not my native language either)
My device:
Nexus 5 - hammerhead D821(H) 16GB
BL version - HHZ12h
BB version M8974A-2.0.50.2.26
Secure boot enabled
lock state unlocked
today i got a "broken" nexus 5 that is in boot loop with the google logo and it wont boot into any .img
At the start i read the pinned posts and found this tutorial: http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701
followed it step by step. but unfortunatly it didnt help my situation. there werent any errors or such kind.
i also tried this tutorial with other images but nothing worked.
When i go to the recovery mode and press the power button the phone get into the google logo and i can see some sort of strange stripes in like a milisecond but then it just gets into the boot loop.
i really think ive tried everything accept for relocking the bootloader but cant imaging that this could be the problem.
If you guys need more info please just ask me.
Hope you guys can help me out here.
Martin
Really thought XDA forums would be able to help me.
Any admins or mods or any other veteran that could help me out?
If that's not working for you, you can try using the Nexus Root Toolkit just to be sure.
If that doesn't work, than it could be hardware related, and not much you can do about that.
Hi All,
I have boot-loop problem for Nexus5 as described earlier .
As I was able to boot in Fastboot
I went for factory reset, and saw FAILED (remote: flash write failure).
I have tried to flash countless time with same error.
Then I read this thread and considered phone memory is toasted.
LG service-center have quoted me around $180 for mother board replacement.
Today I tried twrp project to boot in openrecovery and start an adb shell.
I was able to see file system of my phone.
These following folders are empty:
/boot
/cache
/data
In system folder there is only bin folder and which is empty.
/system
I have gotten this far, is internal memory roasted
Any direction or suggestions welcomed :good:

Are you sure your bootloader is unlocked?
When you boot the phone in Fastboot mode, does the "lock state" say UNLOCKED?
If so, then yeah, your internal memory could be huffed.

It says Locked.
I unlock it using ./fastboot oem unlock
I just got my N5 and was messing around. Rooted it and loaded a rom, but it would just seem to hang at the spinning dots forever. Though I didn't wait THAT long like some users did and had success.
I can't find the link I used, but googling around should get you there. I ended up restoring a factory image via fastboot. I ended up using THIS PROGRAM to root the phone. This program also has a restore option and gives an option to check in case you are in boot loop status. Give it a shot.
Yes I do believe you have to unlock the bootloader as well.

Yes the bootloader must be unlocked before you can do ANYTHING to the phone, it's what's there to protect it from being hacked/changed or whatever. So before you can write anything to your phone, you need to make sure you OEM UNLOCK the bootloader.
[Solved!] Nexus 5 boot loop at Google logo
I found a solution on Youtube comment (can't post url, too new user).
You just have to press quickly the Power button durint 1-2 minutes (continue untill the Android animation start, don't stop when the Google logo appear)3
As crazy as it sounds, IT WORKS
Wow .. i had the exact same problem (Startup loop on Nexus 5 that shows the Google logo and restarts, over and over), and i pressed the power button quicky about 30 or 40 time until after I saw the startup animation and my phone came back to life. I have been charging it with cables other than the one that came with the phone for a few months now, and it has been acting strangely while plugged in (randomly clicking things on the screen, and enabling my camera and taking pictures on its own, etc.). So, to avoid problems in the future, I think I'll invest in a wireless charger. Thanks JackNUMBER for the easy solution. I hope this works for others as well. Saved me a trip to the store.
