[Q] Boot loop (no boot image)

Hey guys! I have no idea where to post, so I apologize if I'm in the wrong section.
I'm very new to rooting and I've seem to come into a major problem. (Atleast in my eyes.) To start off I had gotten my HTC Evo 4g & used the method of UNRevoked to root my Evo. I then found out UNRevoked isn't a full nand unlock & all the nitty gritty, so I came upon Toastcfh's guide to rooting the Evo. I performed half the instructions as told and was then in this boot loop. Right before it happened I (think) I erased the Dalvik Cache, but I definitely hard formatted the whole phone/cache. Anyway as told in the instructions I was suppose to flash the PC36IMG.zip to my phone and I did. Once that all configured it rebooted on itself & now the phone is stuck in boot with stock recovery method. I can load into HBOOT and see that in green lettering it says: SUPERSONIC EVT2-2 SHIP S-OFF, HBOOT-0.79.0000, TOUCH PANEL-ATMEL224_16ab, RADIO-1.39.00.04.26. Please help me. I havent used my phone for a whole day now. :\
To add: Before the PC36IMG.zip got added on my phone, I had clockwork mod recovery. Now I have the stock one I'm guessing. I have tried a stock RUU through HBOOT USB, but the RUU either says some error my phone battery is under 30% (when it's fully charged). Or the RUU will say waiting for device to connect. & I tried putting a rom on my sd card then flashing or whatever and my computer wont open my sd card unless, I put it in the disk reader. Please ask questions, I'll answer as best as I can...thanks!

The current Unrevoked does in fact unlock nand, so you should have stopped there. I am not familiar with Toast's rooting method, so I can't say for certain what happened. The good news is, you are probably fine, you just need to reflash a rom. Since you can't get into recovery, the best way to fix this is to flash a rooted stock pc36img from your hboot. Download the file from THIS THREAD, rename it to pc36img, put it on your sd card and boot into hboot. It will find it automatically and then it will take a few minutes to load it. Once it's loaded it will ask if you want to run the update, choose yes and let it do its thing. When it's done you will have the latest rooted stock rom on there and clockwork recovery. Make sure you delete the old pc36img off your sd card before doing this. Good luck and godspeed.

Did what u said there MetalHead. still getting boot loops at the white htc evo 4g screen and can not get into recovery. Do you have anymore suggestions?

I would try it again but use this PC36IMG.zip instead.

This one is completely stock. You will be unrooted after running it, so you will have to root again.

[Q] Stuck at white HTC boot screen after root

I've recently rooted (unrevoked) and flashed my HTC Desire with Cynogen 6.1.
This worked for the first couple of days until my phone suddenly turned off. Now I cannot get it to boot past the white HTC bootscreen, unless I flash it again with a custom rom (tried Cynogen again, OpenDesire and Miui) with a complete factory reset. Then it will boot once into Android, but after a reboot the same problem occurs.
I've been reading numerous topics on this and similar problems and it seems I have to unroot my phone. Is this correct? On some sites there are warnings you should not root/unroot with a certain hboot version. Is this still the case?; because the unrevoked method states that it rootes no matter what the hboot version is.
So I'm planning to go back to stock now by following the unlocker.com unroot tutorial and flashing a htc europe stock rom (I have the HTC Desire from T-Mobile Dutch).
I'm posting this topic to double check, because I do not want to brick my phone completely
Thanks in advance.

You are right, just flash a stock rom and start rooting again. It doesn't matter anymore which boot version you are using. You have a go

Ok, thank you, will do and will post my results here ;-) I understand from you answer that unrooting and rooting again may fix this issue?

It's possible, you could also try a different SD card. Maybe that is also causing the problems, but unroot first and if that doens't solve it, try switching your sd card. Make sure you use at least a class 4.

[Q] Cannot boot into Recovery!!

So you probably see these types of threads all the time, but this one is different--
So the phone is a T-Mobile G2, Yes, It is Rooted, and S-OFF.
Long story short, I rooted the phone fine, but I cannot reboot into recovery.
I have the newest CWM flashed. It is version 3.0.0.5. When I try to boot the phone into recovery, it simply gets stuck on the HTC Logo screen. But, it is not bricked, but if I remove the battery, and put it back in, the phone boots and its fine. One more time. The phone is S-OFF and rooted.
The only thing I can do is flash CM 2.5.1.3...... 2.5.1.4+ do not work.
I just want to know WHY its doing this. Its my friends G2 and I have rooted mine the SAME exact way, and its fine. I have tried factory resetting it, but it doesn't work.
PLEASE TELL MY WHY.
EDIT*
I'm trying to do this process in ROM Manager- I also have tried flashing it more than once.

If you can boot up normally, load rom manager (download from market), and go to install alternate recovery, and install any alternate recovery. Then when that is complete, go back and install the Clockwork recovery version you want on top of the alternate.
What happens is SOMETIMES recovery will get messed up while installing, and you'll get exactly that, loop at the HTC screen.
If you cannot reflash an old, then the proper recovery through Rom Manager, you can do it via fastboot with your computer and USB, there are a few guides on the developer forum on how to do that. If you need i can try to dig up the fastboot recovery method guide later... but really, if you can boot up, Rom Manager is your best/easiest bet.

Yeah, I'm trying to do it using ROM Manager. and It still doesnt work. Ive rooted- unrooted and did everything, idk what I'm doing wrong. I tried flashing the new recovery like 4 times, it doesn't work for me. Thanks for the reply!

[Q] CWM Recovery rom flashes won't boot

Hi everyone, I've come into a strange problem with my G2 and I bet someone here can help me out! I just got a refurbished G2 because my last one had display problems. I tried to root with one with gfree (05) and I ran into a couple of errors so I rebooted my phone and used the rage method. Anyway, I downloaded rom manager and flashed CWM 3.0.2.4 so I could flash that leaked gingerbread build. It wouldn't work for me, so I flashed xborders' version and it's all good. I went to flash the stock rom (to go back) and when it reboots it stays stuck on the HTC splash screen. The same thing happens with CM7, or any other rom I've tried recently. I let CM7 flash when I went to sleep, when I woke up it was still stuck on the HTC screen.
I'll explain what I do:
1. Flash superwipe g2
2. Flash the rom in recovery
I accidently deleted my froyo nandroid but I have one from xborders rom so I at least have a usable phone. Could my sd card be messed up? I've tried it on the two I have.
I had this problem with my other phone too, no matter what I tried I couldn't get CM7 to work. Now it seems like no roms are working.
After I do flash a rom, it doesn't say reboot system like I think it should? I have to hit back to go back into the recovery menu.

Ended up fixing the problem, thanks to anyone who looked at this!

Care to tell us how you fixed in case someone else comes to this thread for reference?

He probably didn't root the phone properly or the partition table has been messed up. To fix something like that just flash a stock ROM that you know works on the phone and from there you can use any root method to get SuperCID, Permanent ROOT, an unlocked HBOOT and ClockWorkMod. Then any rom designed for the G2/DZ should be flashed just fine as long as the requirements are met.

Recovery affected by rom?

Hey mates,
would be cool if you could help me to understand the connection between recovery and flashed rom...
This is why I'm asking: I rooted my desire a couple of weeks ago (by applying the unrevoked method). Since then I flashed a couple of custom roms. I wasnt very happy because the most roms caused my mobile phone to crash. I thought it was because a broken sd card therefore i bought a new one today. Sometimes when my phone crashed I wasnt even able to enter recovery anymore. And sometimes it did just nothing... I couldnt even enter hboot (it just didnt boot - like it was briked - only the charging led was on when i plugged the charger in). In this case I had to remove the battery a couple of times or plug in the charger. Usually I needed to do this many times. This is btw. why I'm fed up with custom roms but maybe its just my mistake. And now finally my question:
Why can I enter recovery sometimes and sometimes not? Does this depend on the rom? Why do I have to remove the battery etc. to make it run?
I know flashed back to the rom I of which I created a backup after root. But it seems that my phone is more unstable since then (even if its just my rooted stock rom)
Thank you for your answers...

What rom are you on? Maybe your recovery is a bit messed, have you tried reflashing it? Btw, s-on right?

If your not able to get to your hboot then there is something wrong with your phone. It will most likely be able to do with your hardware. You can use an ruu to restore everything back to factory default. You could then root again and see if that will help. But it does look like to be a hardware/corruption issue.
Swyped...

Your Desire maybe being one of the new PVT4 new nand would might cause this. I know that the latest version of unrevoked and Clockwork recovery can't be used to root the PVT4 new nand. I had that problem and the fix for me was to use an earlier version of unrevoked and flash Amon Ra recovery instead. There's a thread around the forums regarding this. Check first if your Desire is of the new PVT4 model. Can't post the link but there's a thread that explains how you can check if your Desire is PVT4 new nand. Would post the link but can't yet, but a quick search should take you to it.

hey guys, thank you very much for your fast answers. The desire is s-on. I'll try an official ruu. If I'm brave enough I'll root again . The strange thing is that I can enter recovery but not always. A hardware issue would be awful. I'll let you know how it went. I hope it is ok to just use ruu to update a rooted rom. It flashes a new recovey too, doesnt it?

Ok, i tried to use ruu to unroot my device. It told me that my bootloader was not compatible and canceled flashing. But it also broke my rom. I couldnt boot the system anymore and i couldnt boot into recovery. I dowloaded a ruu image (with my radio) to flash it via hboot. Everything seemed to go fine but after the first restart i'm stucking with an update sign (i guess its the recovery menu) - a mobile with green arrowrs. I think its frozen. Do i need to do anything else?

Hey, just to keep you up to date. I successfully unrooted my device by flashing a stock ruu. Now its booting (but not always) but it often freezes after a few minutes after the boot progress. I guess I'm going to send it back.
Thank you all for your help anyway.

Yeah best to send it back, it sounds more like a fault with the device
