The phone doesn't boot...

Hi guys, please help me!
My sister's phone ( i9003 as mine ) doesn't boot anymore...
It had froyo and today it stop to work...
i have tried to flash xxkpe and the xxkpq but it no boots!
Do you know any solution?

Have you tried anything such as flashing another phone's ROM? Can you access Download Mode?

It had froyo stock rom...it's my sister's phone and doesn't boot today...i don't kmow why...i tried to flash another stock but nothing, should i need to change kernel?

How have you tried to flash? If you can boot in download mode (Vol Down + Home Button (the central one) + Power button) you'll be able to flash the phone with Odin.

you say "suddenly stopped", and it won't boot, and she has the same phone as you? try swapping batteries first
if nothing is working at all and it won't go to download or recovery and it's 100% stock and still under warranty, the service center will be the best solution if swapping batteries doesn't make it work (dead battery?)

it swich on but stops in boot animation of samsung...is the phone in warranty if i have put another stock rom like xxkpq or not?

The recvery shows while i'm trying to flash another stock...
"your storage not prepared yet, please use UI menu for format anc reboot actions."
and later "E:format_volume:rfs format failed on /dev/block/mmcblkOp3"
"data wipe failed"
those are the red one in the recovery

that's the one I hear happens all the time to those with certain hardware errors. just go tell 'em you were flashing through kies when it broke

if the homescrren doesn't apear the kies don't work...or not?

that would be my guess. I don't use kies, just installed it on my computer since it seems necessary in order to get the usb drivers.

kies wont work until the phone has completely booted

if you can go to recovery then you can do dalvik and cache wipe.... then try to go download mode and flash using odin start with KPE or KPH (i used KPH) before going to anything newer

System Software not authorized by verizon wireless has been found on your phone

I need help guys,
I used Odin to root the phone and did my first custom rom which is the clean rom...it went through the process and when it was about to reboot i got the system software not approved by verizon and take phone to store
I have been told to odin back to stock but it wont let me. The stock image on odin wont work it says fail
I tried the first method and used odin in download mode to flash the stock image
Failed:
This is what I get
added
Odin V3 engine
File Analysis
all threads completed (succeed 0 / Fail 1)
In the Odin Download mode on the phone the top left reads as follow
Odin Mode (Red Letters)
Product Name (SCH-I535)
Custom Binary Download : Yes (1 counts )
Current Binary Custom
System Status Custom
Qualcomm Secureboot: Enable

One thing I gotta mention is that when I got the phone last week it had an OTA update from Verizon which I did install and then a few days later I rooted the phone and when I tried to use Clean Rom it gave me the dreaded Verizon message

Sounds like you didn't unlock the bootloader.

Ya your bootloader is locked again ... unlock it and redo the steps everything should be fine after that

Guys I know that the bootloader is locked but i cannot get back to stock to unroot phone and then unlock the bootloader
Odin recognizes phone but the stock image goes into fail mode right away
I cannot get into recovery and the only thing I can do is go to download mode and Odin but nothing else

You are aware he can Odin flashed the latest OTA instead of that you have provided. Here it is :http://forum.xda-developers.com/showthread.php?t=2046439. This will also help fix his phone being that it is recent. Forgot this link to get him back on track: http://forum.xda-developers.com/showthread.php?t=1974114.

i thought thats what he already tried? but yes you can odin any ota file being that an unlocked bootloader isnt needed.

When I try the VRBLK3 chain it goes into set up connection for like 10 minutes on Odin with a fail at the end each time

I'm not sure being ive never had that issues ... im sorry and good luck

try flashing odin stock ROM, not bootchain

I had a similar issue once. This helpful post by h3llsdr0id eventually got me up and running. Took a total of like 4 hours though lol.

Make sure you have the correct files. This is for the original root66 so it's ICS. Once I booted up and activated I took the Verizon OTAs all the way to JB and then rooted/unlocked bootloader.
edit: I actually had to go back to ICS to reprovision my SIM so not sure you have to go through all of this. Try to odin stock JB ROM like mentioned above.

Thank YOU so much guys you have made my day.
After trying all last night and today I got it back to stock with the OTA file through ODIN. That is all I needed and it went right back to brand new stock phone using 4.1.1
WOW.
I thought I was going to have a dead phone.
Thank you all

Glad you got it up and working!!!!!

Yea I had the same problem but all it needed was a handy flash back to stock. The good thing with making these mistakes is that if it happens again you know what to do.

Hi there,
Could someone please help me. I bricked my phone 3 days go and went through odin and root66 stock to unbrick it. I installed CWR and backed up everything, then i purchased triangle away to reset the flash counter. When I did that I got the software not authorized by verizon error screen. It won't let me get into download mode or recovery. Can I still try to use odin? What should I do? I'd really appreciate some help today is the 4th day I have been trying to fix my phone, only to make it worse.
Thank you in advance

You have to get into download mode to use Odin. It will go into download mode, if you will search, there are ways to pull battery along with button combo to get it there. After rooting, use EZ Unlock 1.2 and that will unlock your bootloader without then unauthorized message from Verizon. Make sure you use only that version, the others don't work.

Pull battery, hold volume down+home+power keys while you put the battery back in. If that's too many buttons to fumble with at the same time you can try pulling battery, put it back, hold all three keys while plugging it into your computer. My old phone worked that way, idk about the s3. You SHOULD get the download triangle and it asking you if you want to continue. Hit volume up to continue then plug it in and odin should recognize it. Get the stock rom image to flash in the PDA slot of odin. Accept the OTA's until you're up to date then unlock bootloader, root, then flash custom roms/kernels AFTER you've done the appropriate reading. Theres a sticky in development takes you step by step on how to unbrick, then unlock and root. Those should help once you get into download. Hope this helps! :fingers-crossed:

Thank you for your response. I tried pulling the battery out and holding volume down, home and power keys at the same time while putting battery in, even as i plugged it into my phone, but nothing but the unauthorized error screen comes up. I should note that my phone is note 2 not s3. I apologize for posting it here, but this thread seemed to be just like the problem i was having.

[SOLVED]Bricked phone

Hi I want to know how can I unbrick my Samsung galaxy s 4g. I believe I bricked because now when I turned on only stock in the logo. Please can you help me with this. I'm leontx's wife. Thanks

If it's just showing the logo and it's there for over 15 minutes, you'll probably need to reflash something.
I'd suggest using one of the one-clicks from http://forum.xda-developers.com/showpost.php?p=19601810&postcount=2 and I'd probably suggest the second (Basic with a Twist) choice.
First, you need to get the phone into download mode. Easiest way to do that is to unplug USB cable, pull the battery out, plug the battery back in, and plug the phone back to the computer. Hold the volume buttons on the left and turn on the phone (while holding down the buttons). It should ask you if you want to go into download mode. Press volume+ to confirm, then unplug the phone from your computer and plug it back in (to make the computer realize that there's a device there). Now run the one-click to reflash your phone. If the flash fails, restart the phone and try again. If the phone reboots to a screen showing a little phone and a yellow warning sign, perfect... just flash it again. That's the alternate download screen, and I get it everytime I use Heimdall/Odin/Kies to flash it.

couldn't get into download mode
Hello,thanks for you help,I'm trying to fix my wife's galaxy s after she wiped and factory reset the phone when tried to recovery by herself.Now the phone is stock in the galaxy s 4g logo forever,I tried to get into recovery or download mode but i couldn't.She told me that the phone was giving her a error message about the keyboard app,then she removed the batt and put it back, the battery showed her almost dead like 1% when was like 79% few seconds before,then she called t-mobile and the person told her to do the recovery mode with the bottoms, she did it and the person ask how much batt the phone had, she said 79%.then the person sugested to full charge the batt,and call them(tmobile) back.So here we go... lol:laugh:.She tried to fix it and got into recovery mode and wiped and factory reset the phone,I dont know what she was doing and removed the batt to reboot the phone.and here we are now.When try to get into download mode the pc not recognize it say USB device not reconognized and the phone just show a loading logo but nothing happen.I just want to know if is possible to fix this or toss it,the phone is rooted with a custom rom,I tried with another batt but the same results.Im realy want to recover this phone to give it to my mother in law thank you so much

i soft brick may phone yesterday, i use to flash my current rom and then reflash it again [clean flash] i just reflash it to save my game replay..
if you can boot into recovery mode, reflash your current rom and then backup and wipe everything exept sdcard then flash again.

Sounds like the battery crapping out on you & crashing while it was doing something important. Usually, a factory reset and new battery can fix. But, If the reset failed, it's not a biggie. find any of the one clicks that you might like to try (lumin30 has a awesome guide/thread w/ links). Batteries are cheap. Sometimes they will swell up when they die. If it spins easy when placed on flat surface is an easy check. There are a couple threads with links to 10 buck replacements around too.

my phone is alive.I could put it in download mode by removing the batt,put it back then holding both volumes bottoms,then connecting the phone to my pc(USB),no power bottom.and voila after putting this in download move everything else is piece of cake thank yall.

No OS installed?

After flashing a volume mod, everything went to hell with my phone(stock rom)I for force closes on chrome/andora and i couldnt use my phone since i keep clicking ok to the fc's notification but they kept coming back.
so i decided to do a factory reset but i dont know what went wrong that now in recovery when i click reboot after the reset it says NO OS INSTALLED DO YOU WANT TO REBOOT?
does this mean i need to flash a new rom or what? I was on the stock rom and i kinda want to go back to that but i dont kno what went wrong

So you can get into recovery? if so did you make a backup before sound mod? I know tdunham was one of the gents that made the sound mod, not sure which one your using created by who? Tdunham has a restore file for volume if problems arise. so if your using his awesome mods you should send him message. If all else fails or you are jus lazy just odin the firmware file required for your phone. Everything will be the same as before jus not rooted so reroot with method you have used not sure when you got phone but I heard towel root doesn't trip knox.

Okay so u have no nandroids??? If not check the box your s5 came in they usually have the firmware it comes with printed on box. If you dont have that either, i would to jus download ne5 which the most recent firmware has new modem, still rootable, and it will put os back on your phone. After you do this make nandroid! They are your best friend!!!! Oh yeah odin isnt recognizing your phone because on samsung phones there is a download mode, with phone turned off, press volume down home button, and power all at same time keep holding till download mode iniates. It will say like loading custom os blah blah...press up on volume and presto odin is recognizing your phone.

As far as making your computer fully recognize and through ODIN(hope u pressed up button once in download mode makes odin recognize!) I would uninstall those old drivers, type into google s5 samsung drivers, prob doesnt mean a hoot but to just to be extra precise, download install new ones. Maybe try different odin 3.07 ....and when u run odin make sure u are extracting package if zip and right click program once extracted and run a administrator. No need to touch any settings once in ODIN besides loading firmware. Fell asleeo sorry for late response.

Download and install cnexus stock rom from the dev section. That should get you running again.
Do you have twrp? Sounds like you wiped the system instead of doing a factory reset.

well i couldnt get odin to recognize phone in download mode. I deleted drivers and rebooted but i always get samsung usb modem failed. and When i do manage to get in to install, it still doesnt show up in odin(.09 and 3.07) and in device manager there is a yellow triangle in samsung modem.
I will try to uninstall everything and delete samsung registry keys as i saw something in google that it might help.

Hit thanks by accident. Yes it should work although I haven't done it on the S5. Once you get a computer working you can use odin 3.09 and flash my full tar no data file. This will get you up to full NE5 without wiping data.

It depends on where you are now. If you are ND2 now then by flashing the Rom (system) you are only bringing your system up to NE5. To get all of the other firmware up to NE5 you need to do it with Odin on a computer. Because some of the firmware won't update using Mobile Odin.
If you are already on NE5 then you don't need to do anything else after installing the rom from recovery.

This may sound stupid, but at the expense of stating the obvious, are you using the original usb charger cable that came with your phone to connect to your pc. If not, you should. I had this problem 2 phone generations ago, I thought I had bricked my phone. Use the original cable. All other usb cables are a Crap shoot.

PLEASE HELP ME with galaxy S2 SHW-M250K Boot problem

Please guys, my galaxy S2 SHW-M20K (Korean) is in trouble.
I bought it from a 2nd hand shop , and it was runing Android 4.1.2 Jelly Bean (rooted stock rom). I had no problem with it till today when I tried to install "CWM Recovery", After searching the web i found a post with two files that supposedly could do the task. These files are:
1. CWM_KT_M250K.tar
2. Tegrak-Kernel-Build-39-for-SHW-M250K-UE18.tar
Using Odin, I triedd the first file but it couldn't work, and the phone could not boot so i downloaded the "rooted factory firmware" and flashed the phone. Everything was ok. Later I tried the second file. Again the phone could not boot and stuck at the logo with a yellow triangle. After waiting for about 5 minutes I tried to shut it down by pressing the power button it did'nt respond. (Now this is a point that I regret), I removed the battery as a way of forcing to turn it off.
Now my phone cannot boot. It doesn't respond to power button, neither does it allow me to enter recovery mode nor download mode. But When i connect to the charger or pc, it start charging and keeps cutting off the charging frequently. But it only allows me to enter download mode when connected to pc. When I tried to flash the "rooted factory firmware", again, the flashing goes smoothly but when the phone starts rebooting it fails as if there is a power cut. Is my battery damaged? Can someone give me a guide on how to fix it?
I need your help gus, I am not an expert in the rootings and roms,
Pardon My English. It's a foreign language to me.

Please guys, my galaxy S2 SHW-M20K (Korean) is in trouble.
I bought it from a 2nd hand shop , and it was runing Android 4.1.2 Jelly Bean (rooted stock rom). I had no problem with it till today when I tried to install "CWM Recovery", After searching the web i found a post with two files that supposedly could do the task. These files are:
1. CWM_KT_M250K.tar
2. Tegrak-Kernel-Build-39-for-SHW-M250K-UE18.tar

As u mentioned, I think that your phone has gone to a Soft Brick. I don't know much about the Korean build, so Google it to solve the Soft Brick. Try flashing the stock rom via odin but I don't recommend it since it may cause your phone to be hard bricked if not done properly.
So go to the service centre, you'll get more help there

I thank you sir for responding to this. From what you have said, I think the best decision is to take it to Samsung service center. (For I have tried to google it but I couldn't get a solution). I would also like to know if it is repairable, and about the cost, is it worth repairing or should I think of buying a new phone?
I am stranded.
