HELP - Flash gone bad (looping recovery mode)

OK, so I flashed the wrong ROM today (I9000HVJH1) and the phone now boots into recovery everytime the battery is inserted. I have tried all the tricks to get back to download mode with no luck. The device is recognized by the USB in recovery and was able to push the root update file but can not get it to apply sdcard:update.zip (just sits there and doesn't respond to the power button unless i hold it). Interesting thing is when I plug the USB in and insert the battery, it never goes to charging, it boots into recovery.
Tried:
1. Plug USB
2. Hold vol up (and down but the keys are now backwards in recovery)
3. Insert battery
and
1. Power down (removed battery)
2. Hold vol up + down + power
and
1. Hold vol up (and down too for a few hundred times)
2. Hold power until Samsung logo then release
and
all combo's with and without the USB plugged into the phone.
Beside the tricks shown on the forum, can anything think of a way to get this phone into download mode instead of it constantly booting into recovery? ADB see's the device, just no root access or knowledge of how to get it to apply the update.zip that would root the device.
Thanks~!

UPDATE!!
After going to T-Mobile on Monday to buy a new Vibrant, I started to think about how to get the "bricked" one working again. I was able to admit defeat for long enough to get a new one but was bothered that I couldn't fix my old one.
I started to think about what I could and couldn't do with the "bricked" one. It would constantly boot start to Android Recovery with error about CSC. No matter what combination of buttons pressed, held, release, the darn phone would never get back to a download mode. Since it could never boot into the OS, ADB seemed impossible. The GOOD news (as it turns out) was when it booted into recovery if I disconnected the USB and reconnected, my computer recognized it and Odin saw it on COM10. I began to look at the batch file for the one click root and noticed the line "adb reboot download". I had messed with ADB the day I screwed up the phone but always tried to do commands after typing "adb shell" and without super user access, I felt doomed. Last night I thought what the heck and powered up the old Vibrant and it went straight to recovery. After another 45 minutes of trying to manually put it into download mode I opened a command prompt and typed "adb reboot download" and the freaking phone rebooted into download mode!!!! So after flashing back to stock I now have fixed the phone
So for anyone who can't get their Vibrant to stop rebooting itself into recovery here is a simple breakdown of what I did.
1 - Power up phone (mine went straight to recovery)
2 - Un-plug the USB and plug it back in (computer should recognize the connection)
3 - Open command prompt and change to the directory that has adb.exe
4 - Type "adb kill-server" and then enter
5 - Type "adb reboot download" and then enter
6 - Phone should reboot into download mode and ready to flash
Make sure you have Odin open with the pit and pda file loaded as there seems to be only a short window of time in which the phone will accept the download and get the status bar moving. If you wait too long, repeat the steps above and start the flash quickly.
I hope this helps someone out that might be experiencing the same problem as me.

Legend Won't Boot to Recovery

Hey guys,
I'm trying to boot into recovery mode on my Legend, but I've had no success as of now. I've tried using Rom Manager to boot to recovery and I've tried backing up my current Rom as well, but all I get is a phone with a red exclamation mark beside it. I've tried booting into fastboot, (Holding down the volume down button and power button) and hit the "Recovery" button, but still no luck. Any solutions would be greatly appreciated. Thanks guys.
PS: Sorry for posting two threads in two days.
EDIT: Solved. For those having a similar problem, all I had to do was run the recovery once from my PC using the file "Recovery-windows" in the Legend tools. It had to push the recovery files into my Legend again because I factory reset it a couple weeks ago. I've been trying to fix it for hours, love getting to the bottom of things.

This also works:
When you get to the red triangle of doom press volume up and power. Then using the volume buttons to navigate and the power button to select choose "install update.zip" (something like that, I honestly can't remember what of actually says) then observe as your phone ends up in recovery.

Hi,
I am new to HTC legend. I have a similar problem, can you please tell me what uyou refer to by "run the recovery once from my PC using the file "Recovery-windows" in the Legend tools." What program is that and how do I get it?
Thanks in advance.

Collectric: have you tried holding the volume up button and then pressing the power button?
For me it takes a few moments of pressing power but then a green box appears and i can move on.

Of course I pressed power and volume down, that's basic.
Unfortunately, I made a stupid mistake and tried to replace the recovery file using
http://forum.xda-developers.com/showthread.php?t=833423
which was prepare for Samsung phone (having the naive thought that Android is the same Android for every one ).
Since then I lost the possibility to go into recovery mode, and the author of the above mentioned program is not answering me, so now I am tryoing to look for a way to "recover" recovery mode ....
Thanks anyhow...

Well when I rooted my phone with theunlockr.com they gave us a legend tools folder and it has the recovery tools to push the recovery files into the phone which worked for me and I can then go into recovery freely I'll give you the link soon.

EDIT: Okay here it is http://theunlockr.com/2010/06/07/how-to-root-the-htc-legend/ make sure you download ONLY the "Legend Rooting Tools" and ONLY that you don't need anything else. Unzip the Legend Root Folder in the root of C:/ Also please do not follow the steps they mentioned as your phone is already rooted.
Here are the steps you should do:
1. Unzip the Legend Root Folder to "C:/"
2. Go to the folder in the "C:/" it should be called "R4-legend-root"
3. Put your phone in recovery mode using the power + volume down and click recovery in the PHONE not the PC.
4. When you're on the red triangle of doom (Make sure you are!) click "Recovery-windows" in the PC (Again located in the r4-legend-root folder which you unzipped)
5. A black box should come up pushing the files to your phone
6. Your phone should be in recovery mode
7. You can now go into recovery mode freely using ROM Manager instead of the computer like I do.
PS: Sorry for the late reply I was off on vacation.

Many thanks man, no need to apologize...
Well, the whole point is that strangely enough I CAN'T go into recovery mode on my phone...
Since that stupid act of trying to work with the Samsung program, when I press power and volume down I get into "Factory mode" which gives me the options to test my device, clear the flash and Reboot.
I don't even have the option to go into recovery mode...
I can try and copy all those files manually, as my phone is rooted. I will copy the files from PC into my SD then move them with my phone "total commander" into the proper folders in the root flash.
Does it sound like a plan?
Thanks again

Hi,
As you probably guessed, root is read only, so I met a dead end. I have no way to go into recovery mode thus can't replace any file in root.
I tried to reboot to recovery using "adb reboot recovery", the phone reboots and get stuck with green HTC on the screen - I had to remove battery, put back, press power with volume down to enter "Factory mode", select reboot and get again normal operation.
Any innovative idea?
Thanks in advance...

Maybe you can try to reroot your phone using the unlockr.com method. But I'm not a specialist at these kinds of issues, I wish to be more help. But is there any you can try to reroot your phone using theunlockr.com method?

Yes, I am working on it but I am not so optimistic as, on the way, they also instruct to go into recovery mode. Anyhow, till I discover something better I'll give it a shot.
Many thanks on your assistance.

As I suspected, its a vicious circle, all the repair methods eventually end in the recovery mode. To recover recovery mode I have to go into recovery mode - sad but seems to be true. I will try to open a new thread maybe there is some Android sage with some trick in the sleeve for me....
Thanks again

I'm sorry I couldn't be of help. If you do manage to get it fixed please tell me how you did it because it would be very useful to know recovery mode is essential for every phone. Thank you and sorry again.

I had a problem with the red exclamation mark when trying to load the recovery image on my phone after rooting with the method on theunlockr.com.
To solve it download a recovery image from here, rename it "update.zip" and placed it in the root of your sdcard.
Then boot up your phone and attempt to load recovery as before by pressing the power button and volume DOWN. When you get to the red exclamation mark screen, press and hold volume UP and the power button. This should bring up the Android system recovery. Select flash update.zip and this will flash and load the recovery image.

Hey, I've been doing this for few months now every time I need to enter recovery after I recovered from a bootloop for installing CM7.
However, is there a way to permanently remove this 'wrong' feature by having to manually click update.zip every time? Can I just restore my Legend back to the original state where it would automatically enter recovery without having to press "Vol Up + Power Button" combo and applying update.zip?
Thanks!

If you look at the top line of the bootloader screen it will have the phrase
'S-ON' somewhere; this means 'security on'. The result is that the /system and /recovery partitions are read-only.
There are instructions here on how to S-OFF the Legend. (xda discussion thread here)
I haven't done it myself. Personally, I felt that the risks of bricking and the time spent researching and doing it outweighed the benefits of a writeable /system and /recovery partition.

So are you saying that this "extra step" resulted from the fact that my phone is still S-ON? If that is so, I guess the benefits of this read-only system allows me to flash ROMs much easier (without having to connect to ADB).
Thanks!

I'm not sure if this is gonna help, but you can try pressing the "BACK" button while pressing power on?

[Q] LG G2 Stuck in TWRP & Device not recognized

Someone please comment with help! My phone was rooted and I flashed TWRP and saved a restore rom of "Stock Root". My phone must have gotten warm and now it only boots into TWRP. I have tried flashing my recovery (Doesn't work), using ADB Sideloader (Never Finishes running), Using Terminal Command (how do I navigate to Start Folder?), and using ADB commands to push file. The big problem I am seeing is my computer is saying that drivers aren't installed. I re-install the drivers I used when I rooted but still nothing. I run adb devices and it is not listed. I just want to get back to my stock root or be able to flash a CM stable. Please help!
I have been all over this site and it is always helpful but this time my searches have not led to sucsess...

Download and install koush adb drivers and then pc will see ur phone and I guess u know the rest.

OK
1. Turn device off by holding power key down until bootloop stops.
2. Hold power, down volume and where the home key would be.
3. choose yes factory reset, should take you back to recovery....

Here is the original directions I followed. Saved my phone. Only works if you have flashable ROM in recovery.
The key thing here is hold the power and vol down and then where the home screen is normally on your blank screen hold down all 3

[Q] Ugh, I'm a retard. I flashed CWM BEFORE CF-AUTO-ROOT.. HELP!

HELP
I know I'm a retard, so please spare me the ridicule.
I accidentally flashed CWM BEFORE CF-AUTO-ROOT. Now when I boot into "download" mode, I get the droid that's flat on its back with a red triangle on top of its chest. I get the error message "no command", and when I plug in my USB cable, neither ODIN or the computer detects the phone as a device anymore!! Good god, what do I do?? Please tell me ADB can fix this! Or something else that I'm not aware of..

That is probably the recovery you're talking about and not download mode. You access download mode by doing the following;
- turn phone off ( or remove battery and put back in but don't press power button )
- press Vol Down + Power + Home Button all at the same time until the warning message appears on the screen then let go of the buttons
-now pres Vol Up and phone will enter download mode
At this point you can either flash CWM or CF Auto Root. But make sure you use the right file for your os ( 4.3 or 4.4 ) or you will soft brick the phone. It doesn't matter if you install CWM first because you can just flash supersu using CWM to gain root.

Holy crap, that was close. I used "ADB reboot download", and it bypassed the farked recovery. Odin detected it and CF-AUTO-ROOT I did! :highfive:
For anyone else who runs into the same situation, download the Android SDK, plug in the phone, start the ADB daemon from a command prompt ("adb start-server"), run "adb reboot download", and poof, you're back into Odin mode..

[TUTORIAL][CM11][4.4.2] CyanogenMod Tutorial for Sony Xperia Tablet Z (pollux)

I went through a lot of searching and trouble to install CM11 on my Xperia Tablet Z, and I'd like to share a tutorial I made for anyone who is also wanting to accomplish this.
All links are in Dark Green because I cannot post links yet.
1. Download and extract the ADB+Fastboot+Drivers zip (alexpja.com/sony/adb-fastboot-win.zip)
2. Now we’ll unlock the bootloader.
a. If you do not have a Phone app (like I don’t on the SGP351), you can either get the IMEI from About -> Status in the settings OR you can find the IMEI right after the IC code, nearby the barcode on the bottom of the tablet.
b. If you do have a Phone app, enter *#06# to retrieve the IMEI.
c. Save this for later use.​3. Place the tablet into fastboot mode and connect it to the computer.
a. Power off the device
b. Connect USB to computer
c. While plugging in the other side of the USB cable into the tablet, hold down the Vol + button.
d. If your speakers are on, you should a sound.
e. We have to install the drivers for fastboot. Open devmgmt.msc via the Run window or in the Start menu and in Other Devices section, you should see S1 Service or S1 Fastboot (anything containing S1).
i. If it is showing a yellow exclamation mark: Follow 3.e.i.1. If it is not, continue to 3.f.
1. We need to download Flashtool and use the driver setup. Download Flashtool (unrestrict.li/flashtool) and install it.
2. Find cmd.exe, right click it, and select Run as administrator.
a. Type in
Code:
bcdedit /set testsigning on
and press enter.
b. Reboot your computer.​3. Once you have rebooted the computer, open the folder where you installed Flashtool (default: C:\Flashtool).
4. Open up the drivers folder and open Flashtool-drivers.exe.
5. Select the first two driver choices (Flashmode and Fastboot) and select “Xperia Tablet Z Drivers” and continue.
6. A new window will appear, continue on with that.
7. A window like this may appear a few times, just press Install this driver software anyway.
8. Run 3.e.2. again and run
Code:
bcdedit /set testsigning off
. Reboot your PC now or after the tutorial.​f. The LED pulse light above it should be emitting a blue-ish color. The screen will be dark.​4. Now we’ll verify if you have fastboot running.
a. Open the tools folder that was extracted from the ADB ZIP and double-click on START.cmd to open Command Prompt in the current directory (all it does is literally open cmd.exe, you can edit the script to verify).
b. Run the command
Code:
fastboot -i 0x0fce getvar version
. If you get
Code:
<waiting for device>
, then you did something wrong. Retrace your steps! (For example, I get
Code:
version: 0.5
)​5. Go to (unlockbootloader.sonymobile.com) and continue until you reach the screen where you put type in the IMEI and an email address. Type in the first 14 digits of the IMEI (remove the last one) and your email address (not sure if name is required). You should get an email instantly with the key.
6. In the Command Prompt, run
Code:
fastboot -i 0x0fce oem unlock 0xKEY
where KEY is the key you received in the email from Sony.
7. Download whatever release you would like to use on the tablet (I’m using CM 11 nightly) from (download.cyanogenmod.org/?device=pollux)
a. Optional: Also download gapps for Google apps such as Gmail, Google Play Services, etc. (wiki.cyanogenmod.org/w/Google_Apps)​8. Extract the ZIP file (but don’t delete it either) and copy boot.img to the tools folder.
9. If your device is still turned off, turn it on and enable USB storage mode. Copy the CM zip to either the internal storage (sdcard) or, if one is inserted, the microSD card (sdcard1).
10. Place it into fastboot mode again (#3).
11. Go back into the Command Prompt and enter:
a.
Code:
fastboot -i 0xfce flash boot boot.img
b.
Code:
fastboot -i 0xfce reboot
c. Enter recovery.
1. Once it shuts down, rapidly tap the Vol + button in order to get into the recovery.
2. Grep_The_Truth's tip: Look at the LED. It will turn orange and afterwards it'll turn purple. You want to press Vol+ as soon as it changes colors.​12. Select “wipe data/factory reset” and wipe it. Afterwards, go back to main menu.
13. Select “Install zip” and either select “Choose zip from /sdcard” (internal storage) or “Choose zip from /storage/sdcard1” (microSD card).
I’ve had varying experience with installing from the /sdcard because sometimes it doesn’t want to mount /data while wiping (/data/media which is /sdcard is safe in wipe) the tablet, so if you were to install the zip from /sdcard with the error present, it would screw things up. I prefer the microSD card route (/storage/sdcard1), and you don’t even need a big one. 512MB works just fine. The actual path would be /sdcard/0/ when looking for the cm.zip in the internal storage.
14. When you have chosen to install from either /sdcard or /storage/sdcard1, select the cm.zip and install it.
a. If you downloaded gapps.zip, install it the same way as you did with the cm.zip.​15. Go back to the main menu now and select “reboot system now”
a. Once, I had the option to install root access before rebooting, I declined (was planning on rooting after tutorial) but it gave me root anyway.​
That’s it! You can now use CyanogenMod with the Sony Xperia Tablet Z.

Getting in to recopvery
I just struggled with entering recovery for way too long and I want to help others avoid this. I kept finding vague instructions.
The step I want to clarify is:
c. Once it shuts down, rapidly tap the
Code:
Vol +
button in order to get into the recovery.
Click to expand...
Click to collapse
This didn't work for me because if you press Vol+ too soon it goes right back in to fastboot mode. If you press it too late you will miss the recovery mode. You only have to press Vol+ once.
Please change step c. to read:
Look at the LED. It will turn Orange and then Purple. You want to press Vol+ as soon as it changes from Orange to Purple to enter recovery mode.

alexpja Thanks for your tutorial, this is very detailed and easy to follow.
my Xperia is SGP321.
I put it into practice and the results it gives me the "oem unlock" is:
FAILED: (remote: Command nor allowed).
I guess you should treat my tablet has the bootloader locked and not allowed (for now??) the unlocked.
I hope someone gives us the opportunity to unlock the devices and in the future can be unlocked.

I had the same experience where at times the steps were a little confusing, especially for a beginner. Each set of instructions would either leave something out or skim over it as if everyone already knew it. That's understandable since they were probably written for that audience. I soft-bricked my SGP311 at least 10 times.
I was even going to write something like this but I got lazy.
One suggestion I would offer is to request the bootloader unlock key first since it sometimes takes a little while and a person can reduce the possibility of having to stop and wait just when they are making progress.
And for anyone going this route for the first time, don't make my mistake - flash exactly what the instructions say to flash, particularly boot.img. Once you have that recovery flashed you have a lot more control over your device. If something goes wrong in a following step like getting boot loops you can still fix it. But if you get annoyed and start poking at it then you can mess up the recovery. Then you have to reset everything to stock and just about start over.
While I don't want to say something stupid like claiming the tablet is indestructible, I found that whether I got stuck in a boot loop I couldn't get out of or screwed it up so bad that all I could get from the tablet was an occasional LED flash, I could always restore it using Emma. It's annoying to have to start all over but it's a huge relief when it boots normally.

for me flashing was fine and without any error but my Tab doesn't boot up with CM flashed...any idea?

Hanging at reboot
Hi.
I tried this procedure on my sony xperia tablet z 311. It unlocked fine and wrote boot.img fine but on reboot command, I get a red light and it hangs there.
I've managed to get it back to fastboot mode (pressing power and vol+, some white blinking lights).
But that's it, that's all I can do with this right now. It's a brick that can get into fastboot mode and that's it. Any time I write a boot.img (have tried a different one also), it writes fine but hangs with a red light at reboot.
Edit:
Used Sony's Emma in flash mode to get back to stock, tried again and it worked.
Maybe the problem was using the pollux instead of pollux_windy download, my bad.

Guess my bootloader won't be unlocked. This is A lot of work. Good job on the write up though maybe one day I'll tackle it.

BOOT LOOP Step 9
All was going well, but step 9 powering on device, now its looping.....Ill use flash tools to put jelly bean on and try again, since i was trying with kitkat...why i suspect kitkat is the issue, before i used to be able to unlock and lock boot-loader with jelly bean but with kitkat it didn't work, which i then forced it via cmd

No GPS
I used the tutorial for my Pollux Windy (WiFi Only) and used the latest nightly. everything went well but my GPS is now broken. Is this a known issue?

Hi,
I've been trying with my Xperia Tablet Z Wi-Fi SGP311. Ran into the same problem. On reboot command the LED was stuck on red for 10 minutes and the cmd window was still open. I unplugged the USB and the LED would not turn off. Tried some things, I don't remember specifically what, but it got the LED to turn off. Now my device can't be detected. I've downloaded Emma and it is not recognising my tablet. I've tried to plug the USB in while hold Vol +, Vol -, and the Power button. No detection for any. All I can do with my tablet is make the LED flash white, purple and red in rapid succession by holding Vol + and Power for 5 seconds.
Anyone know what's happened? I suspect I've completely bricked it :L
EDIT: Apparently there are different modes which you can cycle through. If you hold down Vol + and Power for 5 seconds, the LED will flash according to which mode the tablet is in. The different modes give these flashes:
- 1 White flash
- 3 Rapid which flashes
- A white, purple and red flash in quick succession
To switch between the modes, I hold down Vol+ and Power, and after 5 seconds it will take around 3 more seconds to change modes. One of these modes will not appear unless plugged into a PC. What do these mean and can I do anything with it? Tablet is still bricked.
EDIT2: I've managed to get Emma to recognise my tablet. Turns out the modes do have different purposes. I should be fine now, problem solved. I will just leave the solution here in case anyone runs into the same problem.
Unplug your device and hold Vol + and Power for 10 seconds. At the 5 second mark your LED should flash white ONCE. Keep both buttons held and within 5 more seconds, your LED will flash white THREE times consecutively. This will allow you to enter Flashmode (plug in USB while holding Vol -) and Fastboot (plug in USB while holding Vol +). For Emma to recognise your device, enter Flashmode and you can restore and try again.

Bootloop
I've tried many times to flash cyanogenmod onto my Xperia Tablet Z (SGP311). This is a Wi-Fi only tablet and I have downloaded the versions of CM from (download.cyanogenmod.org/?device=pollux_windy) I've followed all of the steps and tried all of the versions of CM down to 10.2 (I used GApps10.2 for CM10.2). Each version gets stuck in bootloop. I've cleared all data (in CWM - wipe data/factory reset, wipe cache partition, wipe delvik cache) before flashing CM and GApps; however, when I try to clear data I get an error. This is what the tablet says:
-- Wiping Data...
Formatting /data...
Error mounting /data!
Skipping format...
Formatting /cacha
Formatting /sd-ext...
Formatting /sdcard/.android_secure!
Skiiping format...
Data wipe complete.

I'm thinking the "Error mounting /data" is the problem, but I'm not entirely sure, nor am I sure of how to fix it.
Any suggestions?
EDIT: Turns out I'm just really bad with Android stuff. I ended up flashing the original Xperia software, unlocking the bootloader (according to this tutorial's instructions), then I downgraded to 4.1.2, rooted my tablet (forum.xda-developers.com/showpost.php?p=53063218&postcount=14) and installed the PhilZ and TWRP custom recoveries. I didn't get to use them in the end. For some reason CWM kept coming up no matter what combination of buttons I pressed while rebooting. After downgrading and rebooting, I followed the rest of the instructions on this tutorial (from step 7). This time I got no errors while cleaning the disk, cache and delvik cache. Flashed the zip files, rebooted the device and voila, Cyanogenmod11!
Again, I'll leave this edit here in case someone runs into a similar problem. I couldn't get any version of CM until I rooted first.

I followed this guide and bricked my device. If anyone has any tips - PLEASE HELP!
I tried to flash CM11, all seemed to be going great until CM11 and Gapps where installed any I hit "Reboot system now" in CVM. The device never booted again (I which I knew why!), and is now pretty much dead. I can however:
- Enter Flashmode
- Enter Fastboot mode
- Relock/Unlock bootloader
- Emma recognizes my device just fine in flashmode.
So I still think there is some hope, right?
I have tried installing the firmware that Emma suggests, doesn't work.
I have tried flashing a firmware I found on the internet with Flashtool, doesn't work.
I have tried relocking the bootloader and trying to repair the device through SUS, doesn't work.
So, PLEASE, help my sort this out! I would be forever greatful!

download a proper stock (not bricked) firmware for your device and flash with flashtool.

What makes you think that the stock firmwares I've tried are bricked? I've since my post tried one which I downloaded through Flashtool - same result.
