F**king vibrant

Ok I've looked everywhere, maybe not well enough but I have and I can't find the answer to my question. I installed the new official 2.2 on the 10th when it came out in canada here. My phone has worked "ok" for the past 2 days. (lots of new force closes and some major lag in some spots that didn't happen in 2.1) but that's besides the point. Today i was trying to set up a new wallpaper and all of a sudden the screen started flashing on and off. I couldn't do anything to stop it except pull the battery. Now when I turn on the phone it just flashes the opening screen that says "Galaxy S blah blah". and the only way I can stop that is pull the batt. I've tried hard resetting and all that but it always gets stuck at the openning screen. Now I'm still noobish to android stuff. Was too scared to flash anything before the official so if you have any advice that involves other programs/pc i'd appreciate a point in the direction of a walkthrough.
I'd hate to have to send it in and wait the 2 months it takes samsung canada to get it back to me.
Thanks.

Look up the "jig" solution. That will be guaranteed to set your device on Download Mode.

It was the same problem with my Vibrant. Solved with JTAG controller. But you'll waste your warranty in that way. Try jig solution first

option 1
METHOD 2: STUCK AT VIBRANT SCREEN:
(and are not able to use vol+ vol- methods to access downloader/recovery)
You will need the samsung ADB drivers installed for your phone as well as ADB...
ACCESS DOWNLOAD MODE
1) remove back cover and take our sim card and sd-card.
2) take out the battery
3) hold ALL 3 buttons down at the same time. (Vol +, Vol -, Power)
4) while holding down those 3 buttons put the battery back in
5) continue holding all 3 buttons until the vibrant disappears and reappears... once it reappears, release all 3 buttons
6) Setup ODIN and get it all setup and ready... (if you are flashing your phone via odin)
6) now connect your phone to your pc via USB cable
7) open a cmd prompt and navigate to the folder with ADB and type ADB REBOOT DOWNLOAD
8) Your phone will reboot into the download screen... go back to ODIN - A com port should now appear for your phone...
9) Click start and wait for your phone to do its thing
Option 2
***First you must have ROOT***
Download Terminal Emulator from the Market
open terminal emulator
**you may need to change to default android keyboard for proper inputting
1.) type "su" and press enter
a dialog box will appear asking for root access and say yes (obviously)
2.) type "reboot recovery" and press enter
at that moment, ur phone should reboot into Download Mode to load Alternate firmwares for like Eugene's Vibrant4 ROM etc......
this it what it should look like...
#su
#reboot download
Option 3
or you can download and install quick boot from the market which you then can make a shortcut to reboot into recovery with just one click

Sometimes it takes more than one try to get into download mode. I just take the battery out for a little while. Put it back in and hold only the volume up and down buttons while it is off and plug in the USB cable.
One thing though, when holding down the up and down volume buttons, it is very easy to mistakenly press the power button because it is exactly opposite of it.

who is genius problem:SGS not full dead:who can help me

i have problem with SGS i9000 i go to in recovery mode cwm i upgarde it without wipe it
with this rom (I9000_Alpha_HTC_Sense_v0.5)
now my sgs not go in 2e recovery with 3(volume up+home+power)it is not woring yet
main screen (galaxy GT-i9000) appear but it just restart when boot in 3 or 5 sec and usb plugin not long::: in 3sec only after that disconnet
now im not have in sgs software (rom) and 3button not working and not have 2e recovery and CWM all just only have boot screen (galaxy GT-i9000) 3secnd restart sgs
ithink it understand my problem
plz quickly solve my problem

Go to download mode (volume down+home+power) and flash any stock rom with repartition checked. your phone should be okey

Remove battery and try again.
Can you get into download mode ??
If so flash a stock rom with pit 512 and repartitioning checked via Odin .
The rom you installed is Alpha that means not ready for Beta full of bugs use only if you know what you are doing .
ROM does not work is what the post says where it says must read .
jje

i do all
i use odin
i remove battery
im not have (software now ,2e recovery and 3button v up+home+power not working to go in recovery mode)
but my sgs when i connect it with pc usb plugin 3sec and restart

If you have any other ROM zip on your SD card then just flash speedmod kernel with odin to get CWM recovery back (see my signature for link)
If you don't have any other rom zip to update with CWM recovery then you will need to flash a stock rom with odin.

i try with odin but useless
if you have program anther odin give me plz

may be try the reset button, which in the middle of the cam and speaker, search in forum for details

Which part of using odin you didnt understand? just go to download (vol DOWN+home+power) mode and flash with pit.

You may be better off paying a service centre to fix as you seem incapable of following instructions .

I tried using the 3buttons (volume up+home+power)it is not responding
I can not inter to recovery mode or download moded
always my sgs restart in 5sec when i run sgs
recovery mode does not respond
I think it's somehow deleted of the device

warning, I didn't try #2 before, but may save you if you don't have JIG

I thought it would be a great idea to try flashing from to Froyo from Eclair anyway, and while it was going on, my pc disconnected the phone and bricked it COMPLETELY... I pulled the bat, tried all the 3 button combos (they worked before I flashed, I tested to make sure), and nothing worked...
I spent hours looking through the forums and the only advice I saw was to try a jig, before reading that for a 100% bricked phone it would not work...
What to do
- Take of the back case of your SGS, inbetween the camera and the speaker, you will see a little circular hole...
- Take a pin/pen and poke it...
- Hold the hole pressed in and press the 3 button combo for download/recovery mode
It should go into download mode and from there you can flash on a fresh firmware!
I saw NO mention of this hard reset's existence anywhere on the website at all, it worked perfectly for me!

unless you mess with your bootloader (in this case you didn't) you must be able to go into download mode and flash a fresh odin rom with pit 512 and repartition enabled

Hi,
Try installing the ROM provided by 'voluptuary' (http://forum.xda-developers.com/show....php?t=1528984 - [ROM] Clean ROM - Stock UI - RTM 8858 Base - Focus v1.3 - 7.8 Official).
Edit: I do not know if you will be able to get back your data. I am using 'voluptuary's ROM and it is pretty clean.

I reverted back to original ROM 2010
Buddy i reverted back to 2010 http://forum.xda-developers.com/showthread.php?t=1131022
but still when it restarted it again gets logged off after samsung logo:crying:

I had the same problem while flashing one of the custom ROMs and whatever I did, the device used to get stuck on Samsung logo screen - blink for a while and turn off and again the Samsung Logo appeared. It would not enter Download mode nor MAGLDR mode. Here is what I did and it worked, I do not know if it will work for you.
Try the following:
1. Check whether you can enter Download Mode - (Vol Up + Camera + Power).
2. If Download Mode appears select Format and Format your device.
3. After Formatting, again enter Download Mode and install MAGLDR (provided in Voluptuary's ROM folder) and flash Voluptuary's ROM (3.10a).
If you are unable to enter Download Mode try this:
1. If you have installed MAGLDR in your mobile earlier, check whether you can enter MAGLDR mode (Vol Down + Camera + Power).
2. Once in MAGLDR mode you can install the ROM 3.10a mentioned above.
For me both did not work initially and here is what i did:
1. Turned off the phone, and connected the USB cable to the device and connected it to my PC - left it for a while (may be - 20 - 30 mins).
2. Samsung Logo was still blinking.
3. Disconnected the USB, turned off the device (Removed the battery and re-inserted). Pressed in held Vol Up + camera and then connected the USB cable, the Samsung logo appeared again and out of frustration i pressed Power button (Vol Up + Camera was still being held) couple of times repeatedly and voot... the phone entered Download mode. First thing I did was to format and re-install the MAGLDR and I proceeded flashing the ROM and now my phone works fine. Don't know what was the main cause yet.
I hope the miracle works for you too.

behind every miracle there is a reason
Tried everything u said...didn help!!!...
Is there someone talented:silly: enough to resolve this issue?

[ROOT] I can't root my GN3

Hi
For the beginning i want to say thx to the people who will try help me.
Samsung Note 3 SM-9005
Rom: NB3 4.4.2 (kitkat)
I should post it as a reply to the chainfire's post on cf auto root but i can't cause i am a new on xda (and he didn't allow me )
So what is my problem ?
When i tried root with CF all is ok but when odin say 'PASS' there is no recovery boot (the install process, the red android logo)
What i have ? > After my flash my phone try to boot (with Se Enforcing + 2 other stuff blue red and yellow i guess) but my phone can't boot (yes even boot) he only reset and try re-booting.
chainfire's say
*NOTE: Sometimes the device does *not* boot into recovery mode and root your device. Just do the entire procedure again if this happens. If it still will not install root and such, make sure that in Odin "Auto Reboot" is not checked. Then after flashing, pull the battery, and boot with VolUp+Home+Power button to boot into recovery manually. This will start the install process.*
Click to expand...
Click to collapse
So i tried it, i unchecked the auto-boot, flash my phone pull the battery and press the button (without the battery), and after my phone turn off.
When i turn on >> same issue boot loop all time
And to have access on the phone i must go on the downlaod mode and click restard phone...
Well if u could help me .... 90% of my app require root x) :laugh:

Is this the file you used? There's 2 files, one for 4.4 and the other for 4.3. Try flashing the file again.

Yes i used this file
i forgot to say that kingo root is so buged i mean i try also to root with him (on 1s)
He put my phone on download, install the recovery ect
Result: a fake root, in fact even if i have SuperSU (he installed) He said me that i have no binnary installed
I also checked on "Root Checked" no root here
BUT on download mode: custom os + custom binnary
And his chinese recovery work
1 hour ago i used my GN2 to see if maybe it's my computed who have issue with kingo root
Result: Root perfectly my phone
I also forgot to say that i used different odin (1.85,3.09 ect) on admin
And i tried the NA6's rom (maybe was the rom ^^' but nop still no root)

I re-read your reply and I'm a little confused. Did you pressed all buttons after removing the battery? Also, there is no restart phone in download mode, you can only get out of download mode by pressing power button for a few seconds or remove the battery.
Lastly, maybe check you have the correct samsung usb drivers and reactivation lock is off.

Well i know but i didn't even really understand the process to manually boot the recovery (the chainfire's quote)
what i did ? i flash my phone when odin say "reset" i just pull the battery on the table and next press buttons (Volup+home+power)
My phone turn off i replace the battery and i get the booting loop
Maybe my way to process is wrong, i don't even know chainfire don't really explain in details the way to do it....
For the driver i deleted all and re-installed by kingo but in fact all time my device is detected (in all mode) and COM if alway here (also the flash is correct)
I think maybe my process is badly done (maybe i can't understand cause im french)

Here's how I would normally do it.
- download the file and extract to a folder/location of choice
- put phone in download mode by pressing power + vol down + home button all at the same time until something comes up on the screen then let go of the buttons then press vol up then connect to usb on pc
- go to where you extracted the downloaded file, open odin and put the tar.md5 file in the PDA slot and click start
Odin will flash file and automatically restart to apply root ( red android with red letters ) then restart again to android.

OMG dude that work thx to you :laugh::laugh::laugh::laugh::laugh::laugh:
Ok the last post i mean i didn't understand the process of the boot recovery manually (with autoboot unchecked)
But i least this time i used a different thing- what ?- A nokia usb cable
And this time that work and im sure before i did all u said to me.
I worked on 2 night x)x)
Anyway dude thx to help me

No problem.
Enjoy your phone :good:

Zuk Z1 Soft Brick

Dear XDA friends,
i always hoped not to be one of those guys, who f****d up their phones to the point of no return. I really screwed up this time. Well, here I'am writing you about my screw up.
I unlocked, rooted, flashed and repaired all kinds of android phones in the past years, never without problems, but I could always fix it somehow. Not so much this time.
Now I'm stuck at Bootscreen with the Zuk logo. I even have problems pinging the phone via ADB.
Sorry for my noobish question guys. Any help would be much appreciated.

I got this translated from a chinese website:
For fastboot mode:
The phone turned off; keep the connection turned off the data cable to the computer, press: [volume down key] [Power Key] waiting to enter the fastboot mode.
For recovery:
Turn off the device
Press and hold Power key
When vibrates Volume UP key + Volume Down key about 10 seconds
Release all key when Android logo appear then you will see Android System Recovery
Use Volume key to select Menu
Use Power key to Confirm
Can you enter any of these 2 modes?

Does anyone know where can i find the scatter file , MTK ROM for zuk z1, i would like to try the SP flasher tool. Or if anyone have any idea how to solve this issue on lenovo zuk z1,pls. help.tnx

Can y get to fastboot ?

im facing the same problem after i had the stupid idea to lock the bootloader again, before that i flashed the phone successfully with the cm mod recovery and cm 13.
Has anyone found a solution to this ? or do i have to send it back ?
What i did exactly :
I locked the bootloader again and just to test it i tried flashing the recovery again , ofcourse it didn't work which was what i wanted.
Afterwards i rebootet the bootloader with sudo fastboot -i 0x2b4c reboot
now im stuck in a bootloop that i cant even stop , in other words i cant turn my phone off nor can i access the recovery or fastboot
Im feeling so stupid that i locked it again .... i will try to get into recovery after my phone ran out of battery but so far it looks quite bad...does anyone know if i will get a replacement even though it was my fault ? ( i don't need to say that it was my fault ..and the bootloader is now locked again )
UPDATE::
I found a promising thread about this problem, i will report back here if i was successful.

Please help , same problem
I am facing same issue too from 2 days. I didnt even try to flash custom roms or play with boot loader or recovery or anything. All of a sudden my phone entered boot loop. After two three bootloops phone is entering "12 apps optimized of 230 apps" mode, completing optimizing all apps and then failing to start apps, entering boot loop again.
Effort made so far to fix -
1) Went to recovery and cleared cache - didnt work
2) Went to recovery and did factory reset - factory reset did happen but boot loop didnt stop, I realized that factory reset happened because now its saying optimizing 120 apps instead of my 230 apps during the bootloop.
3) Went to recovery, Entered fast boot mode but not able to connect to PC. Fastboot devices is not showing anything. I made sure proper driver is installed after researching on XDA.
4) Went to recovery, Tried "Install update". Didnt install anything but browsed through folder structure and realized my data is intact
It will be great if someone can help me atleast recover my data before I handover phone to service center for fixing boot loop issue.

The link is not accessible now. Can you let me know what you have done. My phone is in a boot loop now and showing only Logo and 'powered by Android' message. It keeps turning on and off again and again.

Guys when u are in fast boot mode .. pls install Twrp ... After insatlling that press power button abd vibration comes hold volum doen+volume up button at the same time ..
Then u will be getting recovery Twrp mode .. then connect it to pc and u will see internal srorage in pc...now u have to copy any rom to the phone and install it via Twrp ... Thats all

Sorry For Re-posting Here. This is Solution
Why this is happening ?
Due to Dirty Flash from Zui or from COS/CMOD but suddenly Bootloader gets locked
May be Due to Some Custom Rom which only works with Old Bootloader ( And you are on latest 2.5 Zui QPST Flash)
Reasons are many. I also did same mistake. I flashed ZUI 2.5 using QPST then unlock bootloader using official site installed twrp after wiping cache system and data , Installed Lineage 0S JAN Build then without rebooting installed Lineage Nightly build (Latest) with Gapps After rebooting Phone goes into Restart endless loop on ZUK Logo. Blink and Vibrate .. After 1hr I figured it out but its 5am So slept.
HOW TO FIX ENDLESS REBOOT ON ZUK Logo ?
-> Identity vibrate patterns (Press Power Key I count 6- 7 Vibration pattern ) After long Vibrate immediately remove finger from power key.
->Once its Done (Phone completely off)
Download QPST and Official COS QPST from this Link https://goo.gl/InWQji OR https://goo.gl/iqrnlI (I am personally Very Thankful to D tech Terminal for posting Wonderful video on Youtube https://www.youtube.com/watch?v=4Dl6JkAVpuM
<- please install all drivers and software.->) @ankurpandeyvns Thanks bro.
Main Task is here and Lots of Patience is required and You also need to be very Blazing fast to achieve this.
-Once you download and install Qpst open Qfil
-Now press Volume Up only and connect USB (Just press POWER KEY only for 1 sec It will vibrate and connect)
-Without waiting hit Download button.
-Voila It will start flashing your phone again and Hence Your phone is now Revive..
-Once Revive You can use it to again flash custom Rom or stick to stock Rom if you want.
Keep Flashing !!!
Patience is Key here. And Don't lose hope.
:good:
EDITED:
While connecting to pc and by pressing Volume key you also need to press Power key for 1 sec or 2 sec until it gets detected. Thanks addicted777 (for tip)

-> Identity vibrate patterns (Press Power Key I count 6- 7 Vibration pattern ) After long Vibrate immediately remove finger from power key.
->Once its Done (Phone completely off)
Download QPST and Official COS QPST from this Link https://goo.gl/InWQji OR https://goo.gl/iqrnlI (I am personally Very Thankful to D tech Terminal for posting Wonderful video on Youtube https://www.youtube.com/watch?v=4Dl6JkAVpuM
<- please install all drivers and software.->) @ankurpandeyvns Thanks bro.
Main Task is here and Lots of Patience is required and You also need to be very Blazing fast to achieve this.
-Once you download and install Qpst open Qfil
-Now press Volume Up only and connect USB (Just press only for 1 sec It will vibrate and connect)
-Without waiting hit Download button.
-Voila It will start flashing your phone again and Hence Your phone is now Revive..
-Once Revive You can use it to again flash custom Rom or stick to stock Rom if you want.
Keep Flashing !!!
Patience is Key here. And Don't lose hope.
