lg mytouch c800 bricked? - General Questions and Answers

hi im pretty new here a friend of mine gave me her lg c800 mytouch to try and fix it for her.. not sure what she did she said she rooted the phone and the root was successful but i have a good idea that she doesnt know what she was doing..i will post a pic of the error screen im getting. but it says
E:Cant find misc
E:cant find misc
Finding update package...
E:unknown volume for path [sd:/download/adb_fastboot_and_other_tools.Zip]
E:Cant mount SDCARD:/download/adb_fastboot_and_other_tools.zip
Installation aborted
facory reset failed
restart factory reset..
now im far from a pro at this i know a lil more about computers and Ios devices..but ive rooted a few phones and to me it looks like she unzipped adb fastboot on her phone from her sd card??
ive tried holding F..A..vol down..and power..Nothing..
ive tried volume up .volume down and power still nothing..
BUT if i hold E..vol UP and power it brings me to a white screen that says S/W update
the big problem is the phone wont stay on long enough to do anything on the computer it stays on 3 sec. then reboots to same screen (computer says phone is unplugged) then phone just keeps restarting.
but the phone WILL stay on when i put it on the S/W update screen..but computer wont recognize the phone at all on that screen
ive tried the adb and fastboot commands but the phone wont stay recognized..it will recognize the phone and say thats its in recovery mode but when phone restarts it dont see phone no more..
well thanks ahead of time if anyone has any input or solution
and hopefully all this will make sense to someone lol
i think this pic will work.. if not ill try again

any ideas please?? or am i completely out of luck?

...do you mean that you can successfully communicate with the phone over USB, but you only have 3 seconds? What way is the phone recognized? Is it visible to adb/fastboot?

Yes In Adb device list it shows the phone and then says recovery..but after that I don't have enough time to type any other commands ..the phone is also recognized in "my computer" as removable device then when the phone restarts seconds later it says device unplugged ..and just keeps restarting on its own till I remove the battery...I just read on the forum in a post that Adb will recognize the phone if it's off but I remove the battery and put it back in and plug in USB and phone turns on and keeps restarting won't even let me turn it off!! I'm losing patience with this thing lol
But I don't get why the error mentions fastboot? Not my phone so if it's not fixable I don't really care but I'm just the stuborn type when it comes to fixing electronics ..again thanks ahead of time to anyone that helps cuz I'm completely lost on this one

Have you tried timing it to send a quick "adb reboot recovery"? If you can use fastboot, you can tell it to boot off a new, custom recovery img, without actually flashing it.

i have the same problem

i used an app on the market to remove bloatware. i removed slacker and the app stated that after two reboots that everything would be fine and the app would be gone. after one reboot the phone has the same screen this gentlemans lady friend has. it looks like the app its looking for is no longer zip aligned properly. someone told me to rename a recovery image the error message to trick the bootloader into thinking the missing app is there. hes an app dev so i figured he knows whats what. ive tried everything the gentleman in this post said and more. hell i have two of these phones and rooted the other and made a backup of that phone and dragged the backup to an sd card and rebooted to see if any of the backed up system apks would trigger a successful reboot but to no avail. i have all the drivers i need and adb commands but nothing works because the phone doesnt stay connected to my pc long enough for anything. please reply with some knowledge. ive been scouring the web for at least a month. i was so happy when i came across this. i actually became a member just to post about this erroer (look up diabolus ae in the forum search field. my post is about 3 days old with a better pic of the screen message. i bought a galaxy s II but i want to give the lg to my son. please help or respond:cyclops:

Normally, if you want to flash a custom recovery through fastboot, people will tell you to run 2 commands:
fastboot flash recovery nameofimagefile.img
fastboot reboot recovery
Since you don't have time to execute those 2 commands, you can tell it to just boot from the .img file, without flashing over your current recovery. (This is actually proper form, as you can test if the .img file works properly without damaging your existing recovery.) The way you do that is to 1st copy a recovery .img file to the root of your SD card, then execute the following 1 command:
fastboot boot nameofimagefile.img
Since you only have ~3 seconds, type the command in, and wait for the right instant to hit enter on the keyboard. If the command is successfully sent to the phone, it will reboot into that .img.
See if that works for you. Good luck.

[Q] Atrix 2 won't boot past "M" Motorola logo

Hey guys,
Forgive me for being frantic and (probably) not taking the steps needed to research this issue, or not taking the time to do so, but I'm sure you can all presumably imagine -if you've not been in this situation before- that it SUCKS not having a phone in this day in age...
My problem: Atrix 2 (Rooted + CWM Recovery) now won't boot passed the "M" Motorola logo upon start up. It won't even allow me to access the factory Android Recovery by holding down Volume Up, Volume Down, and Power. I think I inadvertently bricked the phone? (Hope not!)
Further, the "M" Motorola logo is skewed in appearance, like its not even loading correctly. I'm not sure what to do. This is my first time rooting and getting experienced with custom ROMS.
Anyone able to help this helpless sap?
Thanks is advance to your replies...
Step 1 is where you tell what you did to get into the state you are in. You wouldn't believe how far it goes toward fixing something if you know how it got broken.

If you have CWM recovery on boot can't you just do a battery pull? You do NOT want to let that thing bootloop forever until the battery dies.
The End.

Agreed pull the battery. If you run out of juice you'll be in some serious trouble.
Did you try to flash the fkz? Unless you have CWM on Boot it's the only way you can get your phone working.
Okay, sorry for not giving a full rundown on what stupidity on my part cause all of this. Let me start by saying that (sadly) I am a great big n00b when it comes to Linux, and I thought that despite my research online I would sort of explore the CWM Recovery 'Advanced' sections.
I downloaded ROM Toolbox from the Play Store, and installed a custom boot animation, and replaced -or thought I was- the startup "M" logo with something else. This is what concerned me: After re-booting, the "M" logo was all crazy looking, with a "stretched" "M" logo over the top of the "regular" logo.
So, I uninstalled the app, but the logo was still all messed up. So, I used Root Uninstaller to get rid of the ROM Toolbox files, still no resolve to the crazy boot logo.
So, I went into CWM Recovery Advanced, and wiped everything. The Dalvik, cache, System, Data, etc... didn't think that it would -what appears to have happened- wipe out the OS on the phone.
I tried pulling the battery, and re-booting, won't boot passed the skewed "M" logo still. Tried getting into Android Recovery, and it looks to go through the recovery goes through its thing, but never boots normally afterward.
Sorry for being such an idiot, I really shouldn't have messed with this while half asleep, and again I can't apologize enough for being such a stupid n00b.
I can attach an image of the boot logo if that helps, but I'm worried I am just S.O.L. at this point...
Also, not sure what an FKZ is. I tried to install a 2.3.6 apk file to my wife's SD card on her phone and booting from the file after putting the SD card into mine. Still nothing.
pull the battery, put it back in, and hold vol up and down while turning on. choose ap fastboot at the menu. go to the thread in my signature and under the mirrors there is also a download of the return to stock script. run it while in fastboot and plugged in with usb. DO NOT pull the chord until it is done. when it is you should be good.

Yeah wiping the system partition is a no no unless you flash another rom afterwards. Do like ikrasner says and you should be back to normal.

Thanks for all the help guys, I really hope that something positive comes about this... though, to go without mention, I certainly need more knowledge on WTH I am doing to my phone: understanding flashing ROMS, what dangers come with rooting, and a vast array of other "all things root" that I need to learn up on.
I will try to install from SD card the 2.3.5 zip tonight, but will it (the phone) look for the newest 2.3.6 OTA update and try to ask me to install? How does that work after rooting, will I re-brick my clearly bricked phone all over again?
As always, thanks for all your replies in advance -you guys really know what's going on here!
can you read chinese?
Maybe I can solve your question,but poor of my english.
and what is your phone type?
at&t hktw or china ?

It should ask you to install 2.3.6. Just go into setting>about phone>check for updates. Or you could go and install one of the roms that are based on 2.3.6 such as Lithium Sonya or SCv5.
Okay gang, perhaps I'm just certifiably dumb, or I am simply just not doing this correctly. I downloaded the "Returntostock2.3.5.script" zip file and copied it to my wife's SD card to 'apply update from sdcard' option from the Android Recovery area by holding Vol Up, Vol Down, & Power buttons. What I got was this:
--Install /sdcard ...
Finding update package...
Opening update package...
Verifying update package...
E:signature verification failed
Installation aborted.
I tried to just plug the USB into the phone and run the 2.3.5. script from there. but again- I'm stuck in the crazy skewed "M" logo startup screen with nothing following. That's all the phone will do at this point, other than my getting into Android Recovery.
I'm not sure how or what fastboot is, or how it works. If the phone is plugged into the USB, it will only boot the stupid screwed up "M" logo screen. Noting else.

do not flash this. unzip it on your computer, choose to boot into fast boot in the same place you chose recovery, then run the .bat file that was in the zip.
Sent from my MB865 using XDA
What that file does is reflash your system.img, basically restoring your phone to factory default. And just as a sidenote you cannot flash things with the standard Android Recovery. You need CWM.
did you try apboot mode and ise fastboot to flash system.img ?

Still not working... not sure how to flash from fastboot. I don't have any options to run a file from there, or at least not sure ow to go about that.
Fastboot sample, hope will help you.

So, if I'm looking at this correctly, I need to open command prompt from my computer, and type the commands in from there?
I don't think my computer is recogzining the phone in any way, as I cannot get into the 'manage usb connections' options.
If I have the 2.3.5.script downloaded on my desktop, and l plug my phone in after launching AP Fastboot on the phone, will the computer know where to flash the file to?
I know, I'm a dolt... please bear with me, I really need to get this thing working again -I feel naked without my phone!

Before using the restore script you need to install the usb drivers for your mb865, you can get those from here: http://www.motorola.com/staticfiles/Support/Experiences/Global_Drivers/MotoHelper_2.1.40_Driver_5.5.0.exe
Next unzip the Return to Stock 2.3.5 Fastboot SCRIPT.zip to anywhere you like in your pc (example: C:\RestoreScript\ )
Next connect your phone with the usb cable to the pc and get into fastboot mode for this in your phone press volume down + volume up + power it should appear a screen with some options, use the volume down key of your phone to navigate through the menu until you see the Fastboot option, then enter by pressing the volume up key, this will show you some messages and the finally it should said usb connected.
Then open the folder where you extracted the Return to Stock 2.3.5 Fastboot SCRIPT files and search a .bat file call "Stock Restore" then run the file (double click on it) and it should open a command promt screen with some instructions if the phone is connected correctly and you installed the drivers correctly then in some point the screen will show you the id of your device and it will wait you to press the enter key to start the proccess, press key enter wait all the proccess until the program said to you its finished, after that it will reboot your phone and install the stock 2.3.5 when it boots up you should see the android logo and a progress bar filling up.
when it's done wait the reboot and your phone should be ok.
hope this helps.

My G2x seems to be dead

I'm here, requesting help, i've read (i think) almost everything. Try everything and i'm not able to recover my G2x.
I'm from mexico, and my english it's no so good, i hope that everyone can understand what i'm trying to say U_U
I brought a used T-Mobile G2x from ebay. I was SOOO happy with the phone, a good one, a kickass and it was about $250 dlls for me. I think that was a good deal. The phone was on a average/good condition.
So, i rooted it, then after, moved the rom from stock to CM7 stable.
I changed then to eaglesblood ICS, then another eaglesblood, and then again CM7.
The phone was working very good. Then, a issue appeared.
Some day, the phone was a little slow, then i rebooted it. And then started the pain...
The screen showed the LG Logo, white brilliant. And after a seconds, power off. What!?
I tried to power on again. Nothing. I did the battery pull and then worked fine. I thought that was a simple bug or something.
Later, the phone ran out of energy. I pluged on the wall charger but nothing happened. I left it for an hour and tried to turn it on. Nothing...
Then charged the battery with a multicharger and the same problem. LG Logo, nothing. Checked on the CWM Recovery and did a cleanup of battery stats, nothing. I was desperate, so i've flashed my phone with Eaglesblood again. Vuala, the phone worked... 'till froze and i had to pull the battery... Again, LG Logo... nothing.
The phone boot up by himself after leaving it for an hour or more. But i had another problem... Battery at 999% Or battery stuck at 32% and suddenly dies...
I've checked with the battery app and saw that the battery said 0 mV
I have 2 batteries, and the both with the same problem. One LG, one chinese.
So, i went with a friend of mine, i took borrowed a battery of his LGO3D, and... nothing
The phone works with APX, powers on on the recovery, i even sometimes reads ok the battery and the phone comes alive, 'till i have to reboot it because the phone is so slow after 2 or 3 weeks without a reboot... but it's so rare and random...
I even updated the phone with the 21y baseband and the new stock rom, but keeps doing the same thing...
I'm just at the point that i want to throw the phone to the wall...
There are something that i can do?
Change some piece?
I must say that when the phone read the battery and it's ok, i can charge it normally, works perfectly, usb ok, everything it's like nothing was bad. But the problem is if the phone shut's down...
Get adb working with USB and if using a windows pc open Command Prompt and run
HTML:
adb devices
....Make sure your device is found, an ID number will appear if successful....
HTML:
adb reboot
....Let the phone start rebooting. When "adb devices" works and shows the phone ID again proceed...
HTML:
adb shell
$ su
# dmesg > /sdcard/dmesg.txt
# logcat -v time -d > /sdcard/logcat.txt
# exit
$ exit
adb pull /sdcard/logcat.txt %USERPROFILE%\Desktop\logcat.txt
adb pull /sdcard/dmesg.txt %USERPROFILE%\Desktop\dmesg.txt
exit
If you get a complaint with those last 2 commands; change %USERPROFILE% = whatever your username is where your Desktop is located. (i.e. C:\Users\me\Desktop\dmesg.txt)
Then either email them to me or post them on www.pastebin.com and post links to both files.
I'm a little lost...
First of All! Thanks for the help
And i dont know... The phone must be ON to do that?
The phone right now doesn't power on, just the LG Logo, at this point, when i attach to a computer via USB Cable, the computer doesn't detect anything...
I can enter the CWM Recovery, it's enough??
And a funny thing: The phone NEVER powers ON (Not even the LG LOGO) when usb or charger it's connected.
EDIT:
Good news, i've got adb working, but i don't have su, i'm downloading it thanks
EDIT AGAIN
The last time that i've flashed to stock rom the g2x forgot to root the phone
i've already tried with adb commands, but i got errors when i try...
I guess that i need usb debugging On, and i doesn't have it...
I'm on a dead end??
Go to the ROM for recovery thread in development section, follow it step by step and your phone will be 100% alive and kicking on GB 2.3.4.

If I recall you were the one who emailed me and I sent you links to NVFlash correct? Did that work for you? I'm just trying to see what your question really is. It sounded from you OP that the hardware perhaps keeps failing and no matter which ROM you flash, you eventually get stuck in bootloop like you are now. Are you just trying to get out of bootloop or is this a reocurring problem? If your stuck in bootloop then your only solution is to NVFlash a recovery and push a rom. If its reocurring then we gotta figure out why... thats where my instructions come in. So you need to tell us exactly what you're trying to do.
As for adb yes you can adb from recovery. You gotta go to Mounts and storage > Mount /system though or else the device wont show.

Ok... my first problem: Language. I don't have problem with the reading, but writing... i'll try to put my words on the right place
I don't remember, when i first flashed my G2x i did it with the Rom Manager App... the result came on a bootloop. Then i used NVFlash and flashed a correct ClockworkMod Recovery. Installed CM7 and everything was fine. Then i wanted to try ICS and flashed it again. No problem. I normally follow the guides step by step, and the phone was right. Then, one day the phone froze and was the first time that i had the bootloop with the LG Bright Logo, then dim, and then power off.
The problem not was while i was flashing a rom. Because while i was on the problem, i flashed with NVFlash the original bootloader and then restore the original firmware, and the problem still there. Right now the phone has the stock rom, updated by the LG utility, and the problem persists.
I think that is what you say. The phone doesn't pass the LG Logo screen no matter which rom i flash... What i don't understand is that the phone seems to be ok. When it powers (a week ago) it worked just fine...
I don't think that is a bootloop caused by a bad flashing... i think that is a recurring problem...
I have this 2 folders with tools for the NVFlash, i think that the both of them are right...
One-Click-G2x-recovery-flasher-04-28-12 [Folder]
One-Click-G2x-recovery-flasher-09-23 [Folder]
They have the APX drivers and NVFlash and the One-click-G2xr-recovery-flasher app...
I'll mount the /system in recovery and i will try to get that log. With the /system mounted then i think that i can root the phone...
I'm gonna try... let's see what happen...
Thanks
EDIT: I noticed (when the problem first came) that the sticker of water damage was ripped off... is not there... But i don't know if the phone was really damaged by water, because i'm not the first owner... The phone was working fine for about 6 months and now it's just like i'm explaining...

Installed CM7 and everything was fine. Then i wanted to try ICS and flashed it again. No problem. I normally follow the guides step by step, and the phone was right. Then, one day the phone froze and was the first time that i had the bootloop with the LG Bright Logo, then dim, and then power off.
The problem not was while i was flashing a rom. Because while i was on the problem, i flashed with NVFlash the original bootloader and then restore the original firmware, and the problem still there. Right now the phone has the stock rom, updated by the LG utility, and the problem persists.
I think that is what you say. The phone doesn't pass the LG Logo screen no matter which rom i flash... What i don't understand is that the phone seems to be ok. When it powers (a week ago) it worked just fine...
I don't think that is a bootloop caused by a bad flashing... i think that is a recurring problem...
I have this 2 folders with tools for the NVFlash, i think that the both of them are right...
One-Click-G2x-recovery-flasher-04-28-12 [Folder]
One-Click-G2x-recovery-flasher-09-23 [Folder]
They have the APX drivers and NVFlash and the One-click-G2xr-recovery-flasher app...
I'll mount the /system in recovery and i will try to get that log. With the /system mounted then i think that i can root the phone...
I'm gonna try... let's see what happen...
Thanks
EDIT: I noticed (when the problem first came) that the sticker of water damage was ripped off... is not there... But i don't know if the phone was really damaged by water, because i'm not the first owner... The phone was working fine for about 6 months and now it's just like i'm explaining...

Ok, I bet your partition tables are messed up. If you can get that dmesg and logcat file it would be ideal but if you cant then we just gotta move forward.
First copy all your stuff from SDcard and internal memory into a folder on a PC. Make a backup using clockwork or whatever and also copy that onto a PC just to be safe.
Then you need to search the G2x forum for this batch utility called something like "auto-formatter partition repair tool" or something similar. If you cant find it message me.
Youll want to run that first, its going to completely wipe all of your stuff and reformat the blocks sizes. Once done youll need to NVFlash a CWM recovery again. Then push a ROM over to the phone and install with CWM. (Dont push a stock rom or anything Gingerbread. Ideally push EaglesBlood ICS since I know it works and can help you troubleshoot.
So i would do that first because i bet your upgrade when u said you attempted to install ICS corrupted the file system, which can happen if you dont format /system prior.
Get the utility, backup everything , format the partitions, NVflash CWM recovery, push ICS rom, install, install GAPPS, come back here and tell me it worked

It's a shame that i cannot get that logcat... :/
Well... i have nothing to lose (data, or something), so i searched over the forums and i found this utility:
Code:
[URL="http://forum.xda-developers.com/showthread.php?t=1590523"]http://forum.xda-developers.com/showthread.php?t=1590523[/URL]
I think thats the right one, or at least, one of many...
That utility flashes a CWM Touch, then, i installed Eaglesblood Gingerbread (because the utility said that if i don't, the sdcard will not be recognized) and the gaaps...
Turned off the phone...
Turned On...
But then again, i have the LG logo bright, then dim, then power off :/
Do you think that could be a charger flex problem? Motherboard? I should burn it?? :/
Use the batch cleanup tool, then flash stock rooted ROM. That way you cab make sure something works, and stock is going to be the safest flash. If that works, then you can go on to custom Roms

Yes thats the utility, and the post above by "rtotheichie" is correct too.
You cant flash a Gingerbread ROM. You need to either push a stock/rooted build, or an ICS build. It's that gingerbread -to- ICS thats causing the partition problem (if it even is that). So what you're doing is fixing it then messing it up again.
--> There could be any number of things going on and we can guess at anything but what good is that gonna do? ... You NEED to get that #dmesg log. I would focus on doing whatever you can to get ADB working because thats going to tell us exactly what is failing at boot time. Can you get into Recovery? I wouldn't even worry about starting the ROM, you should focus on getting into Recovery first. If you cant get into Recovery then you didn't flash it correctly with NVFlash. If you can get in, then go to Mounts & Storage > mount /system ...then get that ADB going using my 1st post above. Thats your only hope if you cant get it on your own.

No problem.
Well if you can get into recovery and if you have ADB and the drivers for the phone setup on your PC you should have no problems connecting. Try using a Windows PC if you can, it's funny but ADB is probably the only thing that is easier to get going the 1st time in Windows rather than Linux (Ubuntu).
Just keep trying and run
HTML:
$ adb devices
each time until a device ID shows up.
I've noticed you've posted this same question on like every single Android website that exists; but I'm telling you what the correct answer is and the only way you're going to be able to figure out what is going on is to get to a log file. No one has a magic trick that will automagically fix this from afar. Anything else is just guessing and checking.
In recovery, try going to Advanced > Show log ...what does that say? Also it won't hurt to try going to Advanced > Fix permissions. I doubt that will do anything for you but it won't hurt to try at this point.

And another thing. I've checked my PM's, and saw that i've never send a PM to you. And no, i'm not flooding the entire www with my question. But i think that i should have used a diferent question to describe my problem. This is the first time that i ask for help, after reading and reading on the web, and almost everyone says: "send it back to t-mobile", but that's not an option for me. And my first choice (and olny) for asking help of course it's xda.
I remember that once clicked "show log" and an error pop out, but i didn't try the fix permissions options.

Take out the battery > then put it back in.
Press and hold BOTH the [Power] and [Volume Down-] at the same time and keep holding them.
Keep them both pressed while the "LG logo" appears; shortly after you should see the white logo change to a BLUE logo... once you see that you can let go.
Does that work and get you into Recovery? ...let me know.
One other thing to try...
Plug your USB cable into the Computer ONLY ---Not the phone.
Take out the battery, do NOT put it back in.
Now (with the battery still removed), Press and Hold [Volume Up+] and [Volume Down-] together. Do not press the Power button.
While still holding both Volume buttons together, insert the USB cable into the phone.
Now wait a second or two, does the phone Power On into a "Download mode screen"?
If not, let go of the Volume buttons and unplug the USB from the phone.
Now plug the USB back into the phone. Press and hold the [POWER] Button for several seconds (still with NO battery in, just the USB).
Does that turn the phone on?

I'm currently downloading the service manual and the user manual.
Ok, i tried the first thing. The phone gets on recovery mode. All good.
On the second thing to try:
-I followed the steps just as you said: vol+ and vol- and connect usb cable. It makes a sound of connected device, checked and windows detects a NVIDIA USB Boot-recovery driver for Mobile devices, but the phone screen never powers up or show a download mode screen. When i flash anything with NVFlash it shows the Download mode screen...
-I plugged the phone without battery, and pushed the power button. The phone does not power on. Not even the LG logo or anything.
I'm still trying to get that logcat. But everytime that i want to type "su" on the adb shell says that cannot found su...
Now i'm on recovery.

Whats the status on this are you still dead? Looks like you need to do that partition formatter script now... appears your partitions are messed up. What ROM is on there now?

Sorry, i didn't get the mail of new post...
Yeah, it's still dead...
Today, i put the battery on the phone and it started right away. Battery status ok, everything working fine. But i didn't put a sim card, so i turned off the phone and it's dead again.
I don't know if i'm getting a GOOD partition formatter. But i've already used one... and the result it's the same...
And even tried a crazy method of one guy that put the phone on the fridge for 10 mins and then NVFlashed-it to a stock gb...
And nothing U_U
Power up, show a bright LG logo, then a less bright one... power off...
Thanks for your help...
EDIT:
Today i opened the phone, extracted the logic board and watched everything. A VERY SMALL bga chip (i donĀ“t know wich) had a little crack on it, i cleaned with a soft brush and a little piece came off... Now the phone doesn't boot at all, not even the LG logo... i think that's the end...
If someone can indicate me where i can buy a new mainboard it would be very appreciated. Thanks.

One S dead after trying to flash CM11

Hi there,
i have a huge problem. As there was no warrenty left for my One S I thought about to change the firmware to CM11.
I have to admit that i don't have any experience in doing such things, but i thought, it couldnt go wrong if i follow a tutorial.
So at first i unlocked the bootloader via HTC website and istalled TWRP 2.7.1 (latest version). Everything went well, I placed the ROM into the phones root directory, started the recovery and then whiped it before choosing install and selected the file. After about 30 seconds the phone reported the step was successful and i pressed reboot. Then there was the HTC starting screen and then a black screen.
After that i had no reaction but the blinking buttons when i press the power button for a longer time. But it changes nothing. No normal boot. No access to fastboot. Only if i connect it to my PC there is an aditional device to see, but whitout any access.
I know I did wrong but i have no idea what or how to fix it. I hope you can help me.
ElDorado1993
Now i found a way to get access to fastboot again, but i dont really know what to do now.
Can you give me an detailed tutorial, for jelly bean or kitkat (dont matter) that is surely working now?
My main problem is that i can't copy my files into the root directory as i cant boot the phone.
Does it show up in computer connected devices?
If it does, download stock kernel and ROM and upload to phone and go into recovery[power +volume up while off] and flash them both kernel first.

The problem is the phone wasnt ever shown as device on the pc (like a flash drive) since version 4.1 so I allways needed some tricks like airdroid. So i suppose i need adb commands to copy files and i dont have so much experience in doing this.
Do you know how to use adb?You don't need adb I just wanted to know to see if it shows up there and not on computer you simply need to install the drivers.Try holding down all 3 buttons to see if it powers down. Do what it says http://www.technewscentral.co.uk/enter-fastbootbootloader-mode-htc-one/id_7930 if works go into fast boot. Does it say locked or unlocked. If unlocked go herehttps://github.com/koush/UniversalAdbDriver and get the windows installer if your on windows.
Sent from my ZTE_N9511
I now found out how adb and fastboot are working, but the main problem now is, that it says the sdcard cant be mounted. I tried this tutorial http://forum.xda-developers.com/showthread.php?p=25557817#post25850720 but i dont know how to do the first step. Du i need an extra file and where do i get it from and how to use it. As long as i dont get back this access, i couldnt install any OS. I tried also sideload. It was able to copy but cant install because of the missing sdcard access.
I hope you can help me to become my phone running again.
Go here http://m.youtube.com/watch?v=xWmnHwkDrKk but first type adb devices in cmd. If it shows ur HTC type adb shell and and type mount sdcard next to the "#" once it appears although you should be using the fastboot shell not adb commands.adb should only work on a powered on device or you can use fast boot in cmd while phone is in fastboot not recovery(you did say the phone can go into fast boot right?). Just make sure you got the right drivers and both fast boot and adb. You should get Koush's Universal drivers from my previous post since some phones have multiple drivers and MAY cause problems with cmd. Also HTC one S doesn't have expandable storage correct?
Sent from my ZTE_N9511
Wow. Now I incidentally soft bricked my phone again if you would believe it and nothing works this time.
Have you been able to fix?
Sent from my ZTE_N9511
Okay, i forgot to write but adb and fastboot are working on my Mac. I use the Mac because Win 8.1 has the known driver problems.
I tried a lot now, but i recognized maybe the main problem. My phone is still S-ON in bootloader. For sure thats the problem. Do I need to get rid of it and how do I do. The tutorial i used hasn't mentioned this step, maybe the person was still S-OFF.
The first thing i try now is to flash the original recovery, lock the bootloader and execute the original signed RUU to get back the original software first. Im going on holiday on tuesday and it would be a pitty without the phone. When I get it working i will leave it, and thy it again, when I'm back. Otherwise.......****
Use this tutorialhttp://htc-one.wonderhowto.com/how-to/fix-soft-bricked-htc-one-by-flashing-new-rom-via-adb-0154361/unless its the one you used already. From boot loader you were supposed to have gone to fastboot.boot loader has to be unlocked.From fast boot you flash TWRP.IMG which happens to have a special adb side load feature under advanced options. There you upload another ROM and kernel.here is the full list of supported devices as I don't know what variant or carrier you havehttp://teamw.in/twrp_view_all_devicesAlso, a stock kernel is optional but it always seems to fix my problems.
Sent from my ZTE_N9511
Thank you. But I already did it like this. The issue is, than after using sideload successfully the installation fails because of the known "unable to mount storage" text. And i don't know what to do wrong.
Like I already said, my phone is still S-ON, but can this make a difference?
Now i got it to bring the stock ROM running again, and as I'm on holiday for a few days I'm happy it is working again.
But one thing is left. It seems like there is no 3G/HSDPA connection now, only EDGE. I dont know what went wrong. Did you hear about this problem.
By the way, my phone is the standalone version whithout any provider.
Search the forums about edge only. There is a huge thread on this.

Root Status = ROOTED
I cannot boot into recovery mode (but when i try i get this, look in pic 2&3)
Tablet Type = HKC (NOT HTC) p776a
ANDROID Version I think (98% shure) is 4.1.1 beta JB
What happened = A few years ago 2013 i think a got this tablet then i learned about rooting, roms, and such so i spent the next year or two trying to root the tablet. I finally got it rooted with a chinese root program and all was well (i don't remember the name of the program) then there was a update for su and i pressed the twrp/cwm mode on accident (I think I was talking to someone at the time) and now it does what is shown in the image 1 it is on some boot loop. When I try to access the hboot menu it does what is shown in these images 2&3. Also my tablet has a MicroSD card slot and the battery can not be taken out. the regular bootloop picture is image file 1 that is what it looks like when it does its continuous bootloop and P.S. the tablet turns off and on automatically during the bootloop. To try and fix it i have let it do its bootloop for hours on end turn it on and off tried looking for a compatible rom (to no avail) and let the battery completely die that is about it.

Okay. Just a few more questions.
Does your tablet boot into recovery (picture 1) even if you try to boot normally? (fastboot maybe)
Can you boot into anything else other than recovery? (try different button combinations)
Does ADB recognise your tablet when it's in recovery mode? (if you don't know about this, just post your computer OS and if you have ADB/Fastboot drivers installed on your PC)
If the anwser the the first question is no:
Does ADB recognise the device while it's in the bootloop.

sorry, i forgot to clarify the hboot. it pops up the "words" or whatever then automatically reboots there is no way to select options or keep the device on so i cant use fastboot unless there is a way i dont know of. P.S. the tablet restarts automatically so it is on for like 25 maybe 30 seconds then shuts off then turns back on and repeats till the battery is dead. My thought originally to fix it was to get a rom put it on the sdcard and see if that works but the manufacture does not supply the rom for my model only the p771a. and the only physical buttons are the home, power, the pinhole reset button, the volume and such buttons are virtual on the screen when it is fully on. And picture 1 i dont fully know what that screen symbol is the hboot one is similar but not that but yes it does but to picture 1 nomadder what i do even if i try to get to hboot menu. Sorry if this is a "little" scattered having explaining it. If it would help i can make a video and rar it and upload it here.

My thought originally to fix it was to get a rom put it on the sdcard and see if that works but the manufacture does not supply the rom for my model only the p771a. and the only physical buttons are the home, power, the pinhole reset button, the volume and such buttons are virtual on the screen when it is fully on. And picture 1 i dont fully know what that screen symbol is the hboot one is similar but not that but yes it does but to picture 1 nomadder what i do even if i try to get to hboot menu. Sorry if this is a "little" scattered having explaining it. If it would help i can make a video and rar it and upload it here.

1. Download fixcache.bat.zip on your computer. Extract cachefix.bat from the file.
2. Run it. It should say just "Waiting for device..."
3. Now reset your tablet with the reset button and QUICKLY plug it into the computer and wait a few minutes.
Now try to get to that text in picture 1 and tell me what happends.
Also post the text you see on the computer from the file I sent you.
Tell me if

Umm, you said there is a reset button on the tablet so pressing that would probably reset it.
The error you are getting is because adb is not installed on your PC. Use this simple adb installer to instal adb. When installing just press yes to everything. MAKE SURE THE PHONE IS PLUGGED IN THE COMPUTER WHILE INSTALLING AND THAT IT'S ON!
Now run the file again.
If you want you can add me on Skype: janekmuric

If you want to know what is happening:
You are in what's called a recovery bootloop. It's when you can't get out of the recovery. What is happening in this case is that Superuser app tried to install it's binaries via recovery. Because some people don't know how to install binaries manually, the app puts a file on the cache partition so the recovery automaticly installs the zip upon booting. Now, this would be good so you don't mess up your device, but the zip file it's trying to install is faulty so it just breaks the device.
My attept at fixing this is to delete the /cache/recovery folder so it doesn't just install the file, and instead boots into a working recovery.

30 seconds is more than enough. Especally with an automated script like the one I sent you.
The first thing we have to do to fix your tablet is to establish a working ADB connection. Use the ADB installer i sent you. And look up on how to install Google USB driver for ADB.

[Q] Locked Bootloader with TWRP, Won't unlock anymore

Ok, I'm an idiot. A big one.
I was looking to flash back to stock after using some lollipop roms. I was using TK's toolbox which was an extremely handy utility but in the peak of my madness, I hit lock bootloader with TWRP still installed.
Since hitting lock bootloader i'm not stuck with TWRP and it's crippled my phone since the current ROM no longer seems to be fully functional...I can't seem to download anything else from the web. Everything seems to fail.
I've tried fastboot oem unlock and it goes through the process that appears to be successful but it just boots back into TWRP and it's not unlocked. Does anyone have any suggestions or do I have a $300 paper weight. haha

Believe it or not, I have the same problem since yesterday. Its driving me mad since I'm no expert on rooting/unlocking
Phone gets detected by PC and by the toolbox but I can not unlock my phone again.
I am now stuck with TWRP and the only rom I can flash is Slimkat, all the others fail. If I hit unlock bootloader in the toolbox it goes through the process (fast) and it gives no error, boots back up to TWRP and thats it, but it is still locked
I just want it back locked and stocl CM11
Firstly, don't use toolkits. They are often the cause of issues.

Damn you're lucky!
I'm having more issues because my phone won't let me download anything. It's like there is no SD card detected. I can't get that file onto my phone to flash it. Any ideas how I can do it?
I have ADB enabled and it shows up in my devices but it won't respond to adb sideload oneplusone-bootunlocker.zip
It responds to fastboot commands.. it just won't let me download anything off the net onto the device. IT will however update phone apps.. It's so damn frustrating.

I had this yesterday + I kept getting the message 'No OS installed'. Since it was already half 'broken', out of frustration I clicked everything and used all sorts of commands I could find (not the best idea I know :angel untill my PC detected the internal memory and then I downloaded 6-7 roms just to be sure. Slimkat was the only one without a fail.
How did you get the files over to your phone then if it wouldn't let you send them to it?
I finally got my internal memory to show up by mounting the system in the TWRP recovery.. But still getting an error that the device stopped responding or is disconnected.. However, it will let me open and view any file on the system, it just won't let me write to it.
Adb sideload did the fix for me after a while.
But it looks loke you have another problem.

Instead of trying to sideload the unlocker zip have you tried using the adb push command?

Thanks for the reply. The solution for me was to mount the phone in TWRP. This allowed my SD card to be explored in Windows. However, it still would not allow me to copy files to the main directory and just out of frustration I quickly drag and dropped a PDF file that landed on a folder in the SD directory and it worked. Haha. So I then tried to copy the file inside another folder instead of the main directory. Success. What a headache and big ass mistake I'll never make again.
Note to self. Do not lock the bootloader with a custom recovery still installed. Ever.
