So after an unsuccessful ROM flash my phone was stuck at bootloader for quite sometime...i had a micro SD card reader and inserted it into multiple computers running XP, vista and ubuntu...they all registered that i had plugged something in but wouldn't show it as a disk drive...now i've already figured out how to access it but i put a new ROM image on it and tried to reflash but after the flash when my phone booted up it simply switched itself off... when i switched it back on it went back to the bootloader and tried to reflash the ROM. mid flash it just switches itself off... I realize that this is probably due to the charge level of the phone so i plugged it it but it will be off and charging then it will suddenly decide its got enough battery power and boot up to the bootloader screen until it dies again...how do i stop this vicious loop

Something worth trying:
1.You could take out the battery for one minute or longer.
2.Now put the ROM's .nbh on your SD card [Make sure it is named "RHODIMG.nbh" (no quotes)].
3.Put the SD card and battery in and press/hold Power button and the Volume Down button at the same time.
4.That'll put you in Bootloader Mode, and it should ask you if you want to update your phone's image (something like that).
5.Follow the prompts and it should start flashing (you'll see the bar).
6.Soft reset after the flash says it's complete.
I once went through that and this is what I did. I was able to unbrick my phone.
However, (back in September/October) there was another instance of the same thing happening to someone, but he never got it fixed; he did get the stock ROM and SPL back on it, but had to return it to HTC because it still kept cycling into Bootloader.
Good luck!

Hi, Last night i rooted the phone, partitioned the sd card, installed radio .08 and so on.
Rom were working fine but i just wanted unroot cuz of the warranty issue. Heres to the problem. When i connect the phone it all looks fine. The computer finds it and i can mount the sd card and so on. But when i try to boot with the official ruu it just loses the connection to the computer and stops with the "black" "htc" logo on the screen.
Here's what i've tried: Reformated my SD card with fat32, nandroid back to stock rom (the one you get directly after rooting) and i've tried degrading my radio image to the one .04. have also reinstalled htc sync twice and get same problem...is the phone bricked in any way? im pretty noobish at this so it was foolish of me to try it on my own i know.
I can still flash roms i looks like, just not go back to unrooted
I've done the unrooting process before and it worked like a charm. why not now?
the ROm was Leedroid 1.4 if it helps
Pop onto the #modaco irc channel on chat.freenote.net
This sounds sortable.
Sounds like its just a matter of flashing the stock rom directly from the SD card....Feel free to pm me whilst in the channel
Have you try to boot your phone into Hboot/Fastboot before you execute the RUU?
After you have run the RUU file and it asks you to connect the phone, go to your windows temp folder (start->run->%temp%)
Sort folders by date and open the most recent, inside there you will see a file called rom.zip (about 120 megs) copy that to your SD card and rename it to PB99IMG.zip.
Turn the phone off and reboot holding the vol down key, enter recovery and it should scan the SD card and offer to flash the PB99IMG.zip.
Job done!!
This will also downgrade the radio images, so beware it takes a couple of boots.
I unrooted today and had the same problem, its a simple solution. When you run it the first time it gets stuck on the black screen, dont do anything with the phone, leave it connected, exit the ruu, then run it again and it'll work
I had something like this too. Just close flashing software in windows when it says connection error, unplug usb, plug it back and start firmware flash in windows again.
edit:i was too late.. lol
edit edit: i did unplug, but looks like its not needed
My solution is more elegant though

It sure is nerd way to go!
Im Not sure exactly what happened here, I've been flashing for nearly a year now a variety of ROMs, and this last time seems to have been fatal.
I went from a custom ROM, did the routine task29 before loading a new ROM; the task29 completed, I returned to bootloader to load the new ROM, and it wouldnt load past 0%. I tried to task29 again, and then that wouldnt load past 0%.
I've since tried mtty and doing set 14 0, task 29, task 8, which restarts it, but now I can no longer manually power it on by pressing hardware keys anymore.. I have to leave it plugged into USB and wait for it to auto-turn itself on after about 5 mins, it loads to "Touch Pro 2" screen, then I can press the little reset button and hold down vol key to get to bootloader. However, it only lasts there about 10 second before turning itself off again, showing the orange light like it's charging. Sometimes I am quick enough to get any ROM or manual HardSPL to try and load at bootloader, but it still sits at 0%.
I have also tried to load a ROM from the SD card, which seems maybe the only option how; however, I have heard you need at least 50% battery, and I have no way to see how much battery I have left, or whether its even charging.
I tried to install from SD yesterday, and got to the gray "Loading" screen, and it just sat there.. I wasnt sure how long it normally takes at that screen, so i powered it off, checked my SD card and now that shows as corrupt and cannot even be formatted... pretty much burnt out as well now, it seems.
Did I do the SD card installation right, using my RHODIMG.nbh file at the root? How long does it normally sit at the Loading screen? I have an 8GB mini-sd I could load from, but I dont want it to burn out as well..
Are there any other options?? I cant even send back to warranty, I dont think, because I cant even load back on the stock ROM or relock it...
Moved to Rhodium General forum because not a cooking problem.
Someone please help... I just tried again to load stock ROM from SD card, as well as custom, it just sits on "Loading..." on the gray screen...
Just for the record, I can get into bootloader, but as of now nothing will load past 0%.
I tried mtty set 14 0, task 29 and task 8, no luck...
I'm certainly not an expert, but just thought I'd throw out a few ideas.
Have you tried charging the phone on the wall charger (not USB) for several hours (like overnight). The fact the phone is powering off by itself suggests that you may be low on battery. USB won't charge the battery sufficiently in some cases of extreme low battery. Try another battery or charge if possible.
Having the RHODIMG.nbh file in the root of your micro-SD card is the correct way to boot from the card. Normally, it doesn't matter if there are other files on the card. But formatting it can't hurt at this point.
Only other thing I can think of, is try to re-flash the radio first, and see it that helps. That's all I can offer up at this point. I was going to suggest trying to flash the stock ROM, but you've already thought of that in your latest post.
Good luck!

Thanks for the response; I just tried that (flashing the radio) and it didnt work. Ive also tried flashing a variety of ROMs and nbh files over SD;
It always seems to freeze at the gray "Loading..." screen and get no further.

Try using a different USB cable to flash via the PC. If you try the SD route again, some users report that using a NON-SDHC card solves the flashing problem. Give that a shot and then report back. I can't really think of anything else offhand.

I have tried again using a 512 MB SD card and it still hangs at the "Loading..." screen.
Also, when flashing with any USB cable, I am still stuck at just 0%.. I can get into the bootloader, etc, but it just refuses to flash any image..
My case
The battery was drained yesterday (is not the first time) and ever since then, it won't get pass the window screen in the beginning. It would immediately shuts off after the window screen appears.
I am able to get into tricolor screen
When connecting to the computer, it would restarts instead of shutting off.
Tried:
Reinstalled Hardspl, radio and window rom - didn't help
Any pointers?

Recharge the battery using any External Charger (called universal charger)
Then, put battery back into your kaiser. Keep Camera Button pressed and insert USB Cable (remember you must have sim card and SD card removed). Then Disable USB in activesync and flash with default HTC rom
I was able to install the stock rom.
The phone only load up on one occasion with the following things are met:
sd card removed
connected to computer or charger
and hold onto reset button for 3 seconds
It won't load in any other way.
THe next thing I did was to install an android kernel.
I was able to get into linux with the above items are met.
In the linux screen, I try install the SD card in while it was "waiting for a SD card" <- not sure if I should be even doing this, the phone will immediately shut off.
Could this mean my SD card became faulty? Window is still able to read it via a card reader.
Any help would be appreciated.
Ok so first, let me say I know I done goofed. What happened was my phone (Note 2 GT-N7100) started to choke up a lot, battery life was ridiculously low and then suddenly my phone's language was constantly being switched to Italian.
I thought it might be a virus but a scan couldn't find anything. I deleted almost all apps in hopes it would stop but the phone went on with these weird glitches. In an act of desperation, I decided to wipe out everything and go back to factory settings.
Thing is my phone is rooted and I had the X Note Rom installed. When I tried the factory reset on TWRP, it still went back to the X Note Rom. That's when I dun goofed. I deleted EVERY ****ING THING in a desperate and stupid move.
Now when I press Volume Up + Home + Power I can get to Recovery Mode but I ain't got **** to install. If I press Volume Down + Home + Power I get into Odin mode but get a "Downloading... Do not turn off target!!" message that just hangs there forever.
To top it off, my computer won't recognize the damn phone anymore. Am I ****ed? Can I get myself out of this mess?! Please HELP!!!
Take it easy, download a custom rom, transfer it to the SD card, enter recovery and Flash it.
Since you can't connect the phone via USB, you need a SD card reader (if you have a laptop you 100% have it)
OR
You could flash the stock ROM through Odin, but it's more risky in my opinion. I would go with the 1st method

thanks... i'll try that when i get home (my SD card is there).
I have a HTC EVO 4G. It does not have an OS. I have installed every driver I found or could ever think of and it still ses not recognized when plugged into the computer via USB. When I open boot menu, it clearly ses at the top that it is locked.
Things I have tried.
• Turning phone on into Boot mode and going into fastboot then opening CMD on pc. Entering a specific command with the intention of it running certain files on desktop (it runs them) but all it ses is waiting for device. Probably because it is not recognized by the PC, probably because it does not have an OS. (there was more to the tut but that was as far as I got).
• Doing the previous thing exactly but selecting Hboot USB instead of going into fastboot.
• Downloading a stock rom, naming it pc36diag (zip) (why? because thats the name it checks for in the boot menu). Then putting it in the root of the sd card. I put it in the phone and boom! It worked, It loaded up got to the lock screen, and then the phone shut off because it was low on battery. I connected it to the usb/outlet and tried again. Same thing, shut off again (I think because the battery was dead). So, I decide to plug it in, let it charge. Wait an hour. I turn the phone on and it doesnt work again. So I go into the boot menu and it "loads" it up and then when it ses checking version it pretty much quickly ses, good good and then the last 2 sentences say something about the image being wrong. So I plug sd card back into computer, re upload and re rename the .zip, put the sd card back in the phone. Same thing (the wrong image blah blah).
•Ive pretty much tried everything, there was a few other things I did but I forgot, they where related to the 3 things above. Also, the stock os I tried wasnt rooted if that makes a difference. This is my first time doing this and I have been at it for 2 days. Also, I followed so sO SO many tutorials.
