Sorry I'm a noob at all of this. Successfully rooted my phone today thanks to Honsoon2000's excellent tutorial and toolkit. Then I went to install Android Revolution, which appeared to go successfully and then after I flashed the kernel the phone wouldn't load and just hangs at the quietly brilliant screen. I followed Honsoon's tutorial to the T (or so I thought) and everything went perfectly until right at the end when I flashed the kernel. I can make it back to the bootloader screen though it says "failed to load usb master mode". I can still make it into fastboot and recovery mode...tried recovery, and the process seemed to go sucessfully, but the phone still wouldn't load after...tried reinstalling ARHD-- it's still on the sd card and the install procedure still goes off without a hitch, but the phone still won't load. I've searched around and tried everything I can, to no avail. Any help would be muchly appreciated, and I apologize in advance for being a noob wasting people's time.
Edit: For example, when I follow the steps outlined in the FAQ it asks me to enter the command 'fastboot flash boot boot.img' , but when I do it says 'error: cannot load boot.img'.
Edit 2: So I put my boot.img file from Android Revolution into the data directory of the rooting toolkit and was able to complete the above flashboot command. I was also able to install the ROM off my SD card...however the phone still hangs on the Quietly Brilliant screen...I can't even power the phone down...whenever I try it just reboots...frustrating...really hoping someone can help me...cheers.
Before you begin, make sure that the drivers for the One X+ are installed.
Place the boot image being used on the computer's hard drive.
Boot in to recovery and flash the ROM.
When that is done, boot in to bootloader and connect the phone to the PC via a USB cable.
If the phone isn't in fastboot mode already, use the volume keys to highlight the word "fastboot", then press the power button.
Now, there should be text at the bootloader screen that says "Fastboot USB".
Finally, use the toolkit or command line and flash the kernel with the fastboot command.
This should successfully flash the ROM and the kernel. Make sure you full wipe before flashing a new ROM. If you can't seem to get the new ROM booting, the final choice is to relock the bootloader and run a RUU.
Which phone version you do own? International or AT&T / TELUS?
Did you flashed the correspondant boot.img? Did you cleared the cache? ( fastboot erase cache)
I'm trying to run an RUU but it keeps saying the battery isn't charged enough to flash anything...and this after it's been plugged in all day. Oh dear I think my phone might be done...really sucks :/
Also, it won't let me power the phone down-- every time i try it shuts the phone off briefly and then opens back up to the bootloader screen.
Fixed thanks to sarcasticphoenix. Cheers.
OK so I've tried 3 times to flash a new ROM onto my phone (Android Revolution twice and Eleganzia once) using Honsoon's toolkit...I've followed every instruction to the T as far as I can tell and all 3 times the process has gone perfectly right until the end when I flash the kernel...after that when I reboot the phone it just hangs at the Quietly Brilliant screen. I know how to relock the bootloader, flash the custom rom and get my phone back...but I really want to know what I'm doing wrong so I can install a custom ROM. I know I'm using the right ROM for my phone and am wondering what gives. Being driven crazy here...any ideas what's going wrong here would be helpful. BTW on the last attempt right after I finished and the phone hung I went into the boot loader and followed the instructions in the FAQ for fixing a bootloop...still nothing.
Edit: Solved my problem-- I managed to successfully load eleganzia...the only thing i did differently the last time was flash the kernel BEFORE installing the ROM off the SD card.

That's usually what I do first, flash the kernel and then install the zip via recovery

Which kernel are you referring too? Actually there is one or two kernels available but only for the International version, not the AT&T/TELUS which you seem to have.
I strongly suspect that your boot looping was because you didn't flash the boot.img file correctly or not at all. And you don't seem to install the good ROM version for your phone.
Elegancia has two ROM versions one for International and one for AT&T/TELUS users.
ARHD is for International users.
Please read Q12 of the FAQ.

Lol...yeah I don`t know how I missed that. I ended up getting elegancia successfully flashed and loaded so all is well. In retrospect this was a good experience because there`s nothing like having to get yourself unforked from a bad situation to gain an understanding of what`s going on. Cheers.
I have a couple questions and since I`m not allowed to post yet in the elegancia thread I'll try in this thread first:
1) An elegancia question: Is there a way (widget) to toggle data roaming on and off in this ROM?
2) Is there a way to tweak settings (transparent pull down, selection of launcher etc.) without wiping and reflashing the ROM?
3) What are people's favorite launcher for that ROM? I tried Atom but it was just a guess because I hadn't heard of any of them. I like it so far but am curious about the others.

Ok, this is my first post so be gentle. I tried to root my sons phone and now it's useless. I went thru HTC's website to unlock bootloader due to having HBOOT 1.5. I'm unlocked and thinking life is good but, I loaded several different ROM's and get the same result. It starts to load the ROM and reboots, sometimes it goes into a safemode with the Viper Rom. I've been jacking with this for 2 days and need some help. I can't find a good link for the RUU or PG86...bla bla bla, I would take it back to stock and surrender but, can't even do that. I've installed TWRP and CWM, just to try different stuff, but get all the same reults.
I think you need to flash the boot.img separately. I'm not sure though. There's a thread for flashing with 1.50 somewhere in the development section
We're comin from a pure power source.
I am having the same issue here, I installed several ROMS, it works for a day, but then the reboot attack starts. Constant lockups and random restarts, sometimes 3 reboots in a row.
ROMs I tried to flash:
1. Xperia XE
2. Titan Trinity 3 HD
3. Nocturnal Adrenaline 1.0.2
Maybe it's the kernel, is there a list of kernels that I can flash?
This worked for me
My phone kept rebooting after root before, but I managed to fix it. This will only work if you can get into fastboot. Download the ruu file located here and run it while in fastboot. This will unroot your phone if you have S-On. After that is done, if it still loops, take out the battery and count to five, then put the battery in and hold the power button on the phone until the phone starts to turn on normally. That fixed my problem, hope it fixes yours. You may have to update after you get your phone started and you will lose all your data. Sorry about the link, I updated to one that has a working download.

Unroot my phone?
Is it possible to re-root it?
Thanks all for the posts. I will give some of this a shot and see what happens. I can get to fastboot, and have loaded a couple of things thru the cmd prompt to try and help, but nothing so far. I'm not really sure if the kernel thing is what's stopping the roms for loading. I can't get the S-OFF, I'm unlocked. I can send anything I want thru the cmd prompt, and also flash zips thru twrp or cwm. Would like to start over but ca't even find a way to do that. Thanks again for the posts.
Cardmastr, we're on the same boat, pg86 takes forever to download, so as I'm waiting patiently, keep me in on the loop with what you're doing.
RUU didn't cut it, kept failing. have not found an image file to flash thru the cmd prompt. Still no luck. What can I throw into fast boot that might help me?????!!!!!!
When I started flashing after using HTC Unlock, I ran "fastboot boot recovery.img" - which booted TWRP with the necessary permissions. Then I wiped everything and flashed the ROM. Haven't had any issues with the ROMs I've tried.
Which recovery did you install? Twrp 1.1.1 is your best bet.
The 2.x version twrp or cwm do not okay nice with some phones.
S3nt from my 3D wond3rland
I used the TWRP 1.1.1. Might of messed up with some of the cmd prompt stuff I'm going back thru.

Everyday is Halloween for u dude!! UR a Monster! This little tidbit hooked me up. Thanks to you we are back in game.
When installing a ROM, doesn't it wipe /data, /system, etc for us?
I am a relative noob at flashing roms and rooting phones, but last night I ran into an issue. My phone was having all sorts of problems so I was going to put it back to factory, then start from scratch. I then decided to just flash a different rom. here is what happened.
I deleted SuperSU - this was done as part of the process to unroot and put back to factory, after this step I decided to flash a different rom
Put new ROM on phones internal memory as well as SD card
Wipe data
wipe cache and delvic cache
install new rom
Black screen
In an attempt to unbrick I relocked my bootloader.
Now, my phone can power on (Give white screen and HTC logo), then go black, and I can access Recovery mode. That is all.
I have plugged the phone to my computer and tried running the RUU, but the RUU will not recognize the phone.
I am not sure what to do to unbrick my phone and get it working again. Any and all help would be most appreciated!
Sorry I can't be more eloquent with my words, but I'm at work. I will be responding throughout the day, though.
thanks again so much to anyone that can help!
Try running it straight from bootloader
I loaded into Bootloader, selected Fastboot(USB), ran the .exe and it still won't recognize the phone. However, I did get recovery unlocked again. So I can get into recovery mode, flash all the ROMs I want, mount and unmount, yet still everytime I flash a new ROM it still boots to a black screen. Am I doing this right?
Try a Rom with kernel installer
Thanks! Since I am still a little new could you tell me how I would spot a ROM with kernel installer or could you point me to any one that could work? From then, it's the same process as flashing any other ROM? Do I need to do something with the kernel?
Meanbean and stock with goodies are the 2 that I'm certain of. Meanbean needs to be flashed twice the first time
Thanks so much for your help, I will post my results soon!
Failed
Here's what it says. Sorry for the blurry picture. I followed directions closely.
What version of recovery are you using? You may need to update it. Assuming you have a pc, try mounting the internal memory to pc through twrp. Windows will automatically tell you to format if its damaged
2.1 Updating now
omg it finally worked! Updated TWRP using fastboot and flashed MeanBean. Thank you so much!!!
Ok so here's the deal...
I was running ViperRez ROM and decided it was time for a change and found a few ROMs I wanted to check out. Tried EclipticRez, kept force closing and rebooting before or just after I could finish the phone set up. Tried Nils Business, no luck. So finally tried to load MIUI for ICS and ran into trouble.
Each time before loading these ROMs I used Clean Wipe to wipe before loading the ROM. I am S-on. Unlocked. HBOOT- 2.11
So here's where my trouble is... Normally when a ROM fails to work, I'd simply reboot into recovery, wipe, and load a different rom via zip from SD card. The problem I'm having, besides the ROM not loading and getting stuck on the HTC flash screen is, I cant get into recovery. I can reboot into the bootloader screen, get to fastboot. When I try to select recovery the phone goes black, flashes something quickly on the lower part of the screen with CWM recovery looking logo, then reboots and sticks on the HTC white screen. Another issue, my battery will no longer charge via phone charger, so I had to go out and buy a battery charger today to even get my phone running again since all this drained the battery.
I've flashed the PH98IMG, removed it since it was causing me to constantly reflash it and reboot. Removed the boot img from the MIUI ROM and placed it in the root of my SD card, seemed to do nothing. I've also tried to use abd, although I'm not really sure how to use it, basically tried to follow a few different threads, but when I typed adb devices, the list was always blank.
Can anyone help me to either get this MIUI ROM working or at least get me back into recovery so I can re-load ViperRez that I know was working? I am no expert, so please give detailed instructions if you can. Thanks in advance.

your are s-on you need to extract the boot.img from the zip. go to fastboot and make sure it says fastboot usb
fastboot flash boot boot.img
that will flash the kernel that you need. the ph98img you only need if you are trying to make firmware changes. everything else can be run from the computer.
Also, make sure you are flashing 3.04 roms. Viperrez i think never updated to the global . If you are flashing global roms, you HAVE to do the firmware update.

I kinda understand what you are saying, but the other problem I have is.... When running adb my phone is not listed in the adb devices, although it is listed in the usb devices. Not sure what to do about that.
Are you in charge only mode on the phone?
Is usb debugging enabled?
USB debugging was selected prior to this incident and it was on charge only as well. It was not connected as a usb drive. I cannot get into the settings of the phone to find out what it is now or if its changed.
I would suggest going S-Off, it will make flashing a whole lot easier. As for getting back to a usable state, you should be able to flash a PH98IMG in bootloader. If anything, flash an RUU and go from there.
I made a stupid mistake when unlocking my DNA and flashing a custom ROM (ViperDNA 4.1). I ran the rumrunner S-OFF which seemed to go without flaw. The mistake I made was checking to see if root installed which I'm assuming now it didn't. I installed Clockwork Recovery on it and booted into recovery and installed ViperDNA which gave errors. When I rebooted I was stuck at the boot splash. I tried an unbricking method posted on YouTube that required going into Fastboot USB and running an OEM Lock command and then using HTC's ROM update utility to reflash stock back to it which failed. I've rooted and flashed recovery to a lot of devices so I wouldn't consider myself to be a total noob but I'm at a loss here. Any help would be greatly appreciated! :fingers-crossed:
Black htc screen with triangles on each corner
Man I really need help. ...I tried to flash and something went wrong to where I erased the entire os and I continued to fix this issue because all I had access to was twrp(custom rom) and bootloader. then what was crazy is that it appeared that based on the fact that I was on 4.4.2 kit kat that I was unable to fix it. after researching I found a ruu that didn't have the boot image so I flashed the factory ruu with no boot image and my htc scrren with the status bar filled all the way up but it never moved off of that screen I assume because that ruu didn't have the boot image so I thought that common sense would be to at one of the boot images that I had to the zip file of the ruu without the boot image....that's when I made things worst and now im stuck on this htc screen with the four triangles...my pc wont detect my device and im in need of some serious help....can you help? can anybody help?
I believe i can help!!!

I had the same problem last night. I couldn't get fastboot to work properly and thought I was screwed. Here is what I did:
I downloaded a stock rooted rom and put it on a flash drive. I used my USB OTG cable and booted into recovery. I then mounted the external drive and flashed the stock 4.1 rom back on it and that cleared it up. I haven't re-tried to flash the ROM I tried, but I think my issue was an old recovery version.
Once you get back to stock, update or change your recovery to a new one and then try again would be my suggestion.
If you don't have an OTG cable, I'd suggest at a minimum order one for when it happens again
I'm trying to get the user files off a phone with corrupted cache. When booted normally, it gets stuck on the white T-Mobile splash screen. When booting into recovery, I get an error about the cache and the phone restarts without loading into recovery. Screenshots attached.
I can get into download mode fine.
Using Odin to flash a custom recovery gives me the PASS message, but when I restart the phone, the stock recovery is still there with the same error message. I've tried TWRP and CWM.
I am hesitant to try flashing a custom ROM because I don't want to lose the data. The phone is not important, but the data is.

Dont try flashing a custom ROM on to the phone. Try flash the stock ROM through the lastest odin with the lastest drivers and let me know how that works out for ya. Unless that wipes the phone ( havent used it in quite some time) then I have no idea man.
I tried flashing the T399UVUAMJ4 ROM throught Odin. It went through the entire process and rebooted, but nothing changed. Does this mean the bootloader is locked?

I'm not sure maybe want to ask someone else I'm not as experienced as some people on here. Sorry man goodluck
I hope someone can help you out. I would say your cache partition somehow got renamed but I'm not sure if thats possible and if so how to fix it. Maybe someone with ADB knowledge can help?
Also what TWRP were you trying to install? I've had problems when I tried to flash older versions
okay so here is a site with the original firmware for the phone. It has both the t399 and the t399n for odin. It has them labeled so its not too confusing lol. http://forum.gsmhosting.com/vbb/f200/samsung-t399n-metro-pcs-firmware-here-1899016/
find the one for the t399, flash it with odin. this will fully restore your phone. HOPEFULLY it will be able to save the data. I know you said you did this before but I'm not sure if it was just system or everything like here.

Thanks for the quick reply. Its a shame to hear that it didn't work
How did you come to this? as to me it seems the partions have be modified hence why giving those errors I seen similar errors to when users change cache sizes which tends to brick device or from using incorrect pit files.
You never be able to recover data from flashing Odin may be slim chance by custom Rom thru recovery if was a bkup of original system and not selecting data your old data may conflict causing either bootloop or basically stuck on splash screen.
If you was ever able to best way to pull data from device would be thru adb may have a chance.
This phone belongs to a friend of a friend. They said they brought it to T-Mo because it hung up during boot. The store worked on it for a few minutes, but couldn't get it to boot up either. When I tried to go into recovery, they said the store already went into that screen too. They have since bought a new phone, but would like to get the photos off it if possible. They never had an SD card so it's still on the device.
At the moment, I can just go into download mode. I was hoping to flash a custom recovery so I might possibly be able to ADB from there since it won't load the stock recovery.
I have a very similar issue but without "cache error messages". The phone (Samsung Galaxy Light with stock ROM and TWRP) just reboots no matter what I try to flash into it.
It does it while "drawing" the Samsung Logo animation (blue ring that gets created revealing the word samsung), so after the white wrintings of the phone name.
My attempts so far:
1. Flashed newer version of TWRP
2. Flashed CWM
3. Flashed two different versions of stock ROM (the original one and the one that T-Mobile released when upgraded to latest jelly Bean)
4. Flashed a custom ROM (Light ROM found here which is based on the stock one).
EVERY TIME the outcome was the same:
Phone reboots right after the phone name (written in white) while the Samsung animation starts. It just stops while the blue oval begins to appear. If I try to boot into recovery (via home/power/volume up combo) it shows the TWRP splash screen but it reboots right after and this happened even after I flashed (successfully according to Odin) CWM.
It really looks like I did nothing so far but I can assure it's not the first time I use Odin (4 different versions) to flash a custom recovery or a ROM. I did it successfully on other 4 different phones (all samsung).
On this same phone I did it the first time when flashed TWRP in order to root it via recovery.
I have no idea what to do next. I was thinking about using adb in order to wipe all the caches (dalvik included) but it looks like the phone can't be recognized unless I boot it into recovery mode (adb get-state returns "unknown") and I don't think I can do anything in Download mode which is the only mode I can enter apparently.
I was hoping someone here can help me to spare some money buying a new phone for my wife and tossing this one which is the best for its small size imho.
Thank you in advance to anyone interested in at least shading some light on what could have happened. This started to happen out of the blue and the last time I actively modified something (updating the recovery) was almost one year ago... It always worked like a charm until 4 days ago...
EDIT: To clarify: the reason why I posted here is because this looked like a problem the most similar to mine (boot loop or stuck at boot and can't enter either regular or recovery mode). I cannot create new posts due to my low "rank" yet... Please feel free to move this if you think it belongs to a separate thread.

ok so i read all that you have done which is basically everything i would of suggested to you other then could it be the battery may be faulty just random thought noticed you never mentioned trying kies you may have a chance with it beening detected as i see you can enter download mode so that help with odin also kies also have you tried firmware from here sam mobile here T399 or T399N OH2 lastest for tmo and OH3 for metro.
Try to only flash that thru odin i use 3.07 or 3.09 only difference is the pda button changes to AP .works perfect for me so i suggest it then returning back to stock recovery/firmware if it boots then awesome. then return to TWRP 2.8.4.0 beening lastest for this device also needed for CM12 also my projects for device current and future.
when using odin make sure that only “Auto Reboot” and “F. Reset Time” options are selected.
also just note when going into twrp release buttons as soon as you see logo otherwise it will continue to boot thru well happens to me when daydreaming lol.
also if your seeing this adb get-state returns "unknown" i believe installing kies may install the drivers for detection im not postive on that but im sure it something to do with missing the adb driver for device maybe another dev can confirm this ?
hopefully this may be of some help i keep on thread to see how the outcome goes
Thanks for the reply DJBoxer!
Regarding the battery it's a new one and I can confirm it's not a battery problem considering that the phone can stay in download mode and unplugged from any power source for very long times without turning off/rebooting and it never failed to keep the charge so far. I also tried with the old battery and the phone behaves exactly the same way.
I used 3 different versions of Odin (1.87, 3.07 and 3.09) with only “Auto Reboot” and “F. Reset Time” options selected and every time I got the PASS message even though the phone keeps rebooting after the first reboot once the procedure is terminated.
To clarify one thing : when I said "it shows the TWRP splash screen but it reboots right after and this happened even after I flashed CWM" I meant to point out that it looks odd to see the TWRP splash screen (even for just a few seconds) after I just flashed CWM and that makes me think that I'm really not flashing anything here...
Thank you very much for taking the time of posting the links and I actually didn't try with that latest OH2 version.
I am downloading it right now (it takes a while from sammobile) and I will keep you posted on the outcome.
I will try to flash it via Odin and I'll also try the latest version mentioned on sammobile (Odin3_v3.10.7).
Regarding Kies I wasn't able to have it recognize the phone. I may be missing something but I tried updating drivers and going through all the guided procedures with no luck... If you say it should recognize the phone right away while in download mode then something is amiss.
Could you please confirm that I should also be able to use adb commands with the phone connected via USB in download mode? Cause that doesn't look like the case either...
Thank you again and I'll give updates here about my last attempts.
Sorry for the late reply...
Nothing changed by the way...
I am about to send the phone back to the seller who told me they'll try to fix it. Let's see how it goes.
