[Q] P3100 Unlock Bootloader, FastBoot, Modes

I apologize if I have understood this all incorrectly, but kindly clarify the following for me.
What I have already done:
1. Installed CWM (ClockWorkMod) on the tablet: Galaxy Tab 2 7.0 using Odin
2. Installed the rooting zip file from external sd
3. Made a backup image on an external sd
What I need to do:
1. Flash a custom ROM onto the device from my PC using fastboot
Errors:
1. Fastboot devices returns nothing (absolutely no response... please find the attached pic)
2. Adb reboot bootloader - just reboots the OS (not in fastboot)
3. Fastboot oem unlock says waiting for device endlessly.
My Queries:
1.I have a recovery mode and download mode (aka odin mode). Is either of them the FASTBOOT mode or is fastboot something completely different. If so how to get into FASTBOOT mode??
I read I have to get a USB icon and a Fastboot mode display on screen. I do not.
2. Why is my device not showing under fastboot devices (on download mode, neither show the device.), but adb devices shows the device under recovery mode
3. Is it possible to flash a ROM using fastboot if I have CWM installed. Or does CWM disable fastboot?
4. Also does this device have a Fastboot mode at all? If yes how to get into Fastboot mode??

From what I've read here, there is no fastboot mode on the Tabs.

In that case, how do I flash a custom ROM onto the device?
Thanks!

load it on your external sdcard, boot into cwm and do a fullwipe/factory reset then install the zip from sdcard. poof, rom installed
to boot into cwm, turn off the tablet.
press and hold power and volume down (the one closes to power button) once the samsung tablet logo appears let go of power and continue holding vol down until cwm appears (this can take a couple minutes)

Thanks then!

So... Don't update? I'm still on the original firmware, I don't see any benefit to updating.

Are you taking the update with any toggle mods, root (I.e. Superuser.apk installed), deodexed framework, battery 1% mods, power menu mod, custom boot logo, animation, etc? I never had problems taking the update with stock rom/recovery, unrooted, with no mods installed. I used this guide to restore stock when I was softbricked and bootlooping and the update worked after restoring stock recovery.
Sent from my XT897 using xda app-developers app

screen comes like for a millisecond and then this " starting services" logo doesn't go at all...it just continues forever
any help would be appreciate .

Thank you! Fixed soft brick after a bad system.img flash.
Still wont update. i get a dead android logo after about 30 seconds into the update, then reboots to "The software update failed!"

this is a bit outdated now that we have working RSD Lite files follow the instructions here and use the supplied files for your carrier Sprint or cspire.

Hi. I'm trying to figure this out, but the link for stock recovery you posted is dead.
So I want to clarify what you wrote above... are you saying to follow the instructions here (first post in this thread) but use the recovery.img from one of the zip files in that other link (i.e. asanti_c_sprint-user-4.1.2-9.8.2Q-122_XT897_FFW-5-6-release-keys-cid9.xml.zip)?
Do I need to use "RSD Lite" for something? You didn't mention it in your instructions, but it's mentioned a lot in that other thread...

You can use the RSD Lite file to return to stock the method in this thread was back before we had working RSD files

[Q] Help Revive my Xoom

Hey All,
My Dad's Xoom died over the weekend - 13months after purchase so is not covered by the warranty. He was browsing a site, it came up with a "Internet is not responding - do you want to continue to wait" message and he clicked Wait - after a second the tablet knocked off. It will not come on by pressing Power and only turns on by pressing Power and Vol +
It gets past the Motorolo logo screen and the device starts the boot animation, about 20 seconds into this it freezes and reboots - this continues in a loop. It's been GEDified and was running the last OTA update 4.1.2 - no root etc.
I can get into the stock recovery and performed a factory reset - but the same thing happens. I've also tried Update From USB with an OTG cable but the screen just shows Choose a package to install and under it has /sdcard but nothing else. I have a dummy zip on both the Flash disk and SD card so it's not reading either.
I've also tried to perform update via ADB - when I select it and connect to a PC (Win 7 32bit) it tries to install drivers but I see In Computer Management that it shows under Unknown. ADB Devices returns List of devices message but nothing under it.
I've also selected the fastboot command at boot, tried fastboot devices and the command does see the Xoom.
So my questions
1) Anyone seen anything like this issue before and know how to fix it?
2) Is it best to try to reinstall the ROM? If so, how do you suggest I can see it with ADB?
3) As I have Fastboot command, could I try to install CWM and see if that sees a ZIP on the sdcard - so I can install a new ROM.
Any help much appreciated :good:

so...I've just done a fastboot oem unlock
and then tried to flash the CWM recovery using the fastboot commands - no errors, press reboot and go into Recovery but still getting Android system recovery 3e :crying:

So just to add to this, I found the stock recovery.img, boot.img, userdata.img and system.img and used the fastboot commands to send all to the motorola - all succeeded without error....still the same problem though.
I installed RSD lite and tried a few SBF files but I'm getting an INI error - off to google possible solutions to that now

[Q] Please Help, Xoom eternal loop

I have 2 Xoom tablets, in Germany, and I took the SD Card from one of them to put it on a new phone, the Tablet kept working fine until last week that I forgot to plug it and the battery ran out. When I charged it and started it, it didn´t work again, I got the Encryption message, nothing happens when I click the Reset Tablet either, I tried putting the SD card from my other Xoom but still nothing. I enter the Recovery mode and did a Factory Reset and the tablet was OK.
Battery run out again yesterday and got the same problem once again, but now factory reset is not working, tablet stays stuck at the "M" logo after doing it, I have repeat the operation a zillion times and nothing, it stays on the M. Plus I can´t turn it off either.
The model is the MZ604 and Android Version 4.0.4
I connected the xoom to the computer after installing the drives but it won´t recognize it. I got to do the fastboot and flashed motorolas images but nothing. I can´t do the adb reboot bootloader command because ADB won´t work, because I don´t have USB Debbuging checked, but I can´t check it now because I can´t get to settings (
What can I do to recover the tablet?

Anyone, is driving me crazy, no matter how many time I flash new images it always stays on the original, so I can´t flash any special recoveries either
I tried RDS too and after the reboot stays the same in the M logo, nothing changes. What can I do?

No ideas? :crying:
I want to save the tablet if possible.

Hi, could you explain exactly what you've tried?
In particular what you mean by "I got to do the fastboot and flashed motorolas images but nothing." and "no matter how many time I flash new images it always stays on the original, so I can´t flash any special recoveries either"
By flashed Motorola's images do you mean you flashed the stock images?
And when you say you flash new images but it always stays on the original, I assume you mean the recovery stays as Xoom default?
Let me know and I'll see if I can help.

Yes I mean stock images, and yes, it always stays on Xoom default, it never changes no matter which Recovery image I flash.

The recovery is likely reverting to default because the Xoom does this automatically each boot.
We might be able to give you a recovery that stays put but the booting issue may or may not be something worse.
Being able to fix the recovery in place is reliant on adb working from recovery itself, which I'm unsure is possible.
Whilst you seem to have reasonable knowledge of flashing and using adb/fastbbot, I'll give full instructions.
I assume you have the necessary files for fastboot so I'll skip that.
Place your chosen recovery image in your fastboot folder. (I recommend ClockworkMod Touch recovery from here)
Hold shift and right click the folder containing your recovery image and fastboot files, then select 'open command prompt here'
Your PC is now setup for the fastboot process.
Connect your Xoom to your PC.
Power on your Xoom and once you see the Motorola logo, wait about 3 seconds, and press volume down.
The screen should show the Motorola logo in the center and '--> Android Recovery' in the top left.
Press volume down twice more until the top left says fastboot then press volume up.
The screen will say 'Starting Fastboot protocol support'
Now on your PC, in command prompt run the following:
fastboot flash recovery xxxx.img
Rename xxxx.img to whatever your recovery .img file is named​Once verified, reboot by holding Volume up and Power. (Keep connected to PC and keep command prompt open)
Again, when you see the Motorola logo wait about 3 seconds and hit volume down. You should see 'Android Recovery' in the top left corner, now press volume up to enter recovery, you should now see your flashed recovery.
This is where I'm unsure. Try running the following:
adb remount
adb shell mv /system/recovery-from-boot.p /system/recovery-from-boot.p.old
adb shell mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.old​If you are able to run this, this will rename the files that are reverting the recovery to default and prevent it happening again. If not, we can go ahead with attempting to flash stock images anyway.
To flash stock images download Build H.6.2-24 for Retail Europe (found here.)
Extract the files to your fastboot folder.
Again, reboot your Xoom, either by holding volume up and power, or from recovery.
And again, after about 3 seconds press volume down 3 times until the top left says '--> Fastboot' then press volume up.
Now run the following from command prompt:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot oem lock​This will wipe all data on the Xoom, and hopefully reset it to stock.
Finally, run:
fastboot reboot​and you should boot into Android 3.2(?), fingers crossed.
If you require further clarification or help let me know.

Thanks for the info, sadly I have done almost all that, I can´t use adb commands because I never allowed the tablet to do USB Debbuging, since I wasn´t doing anything that needed that and never thought I would need it. I think I didn´t kept the tablet connected to the PC, so I will try again and let you know if it works.

Like I said before, I'm unsure whether it'll work as I'm not an expert.
However, you may find this helps:
Whilst in recovery and connected to your PC, open Device Manager, find your Xoom, usually under 'Other devices'.
Then right click on your Xoom > Update driver software... > Browse my computer for driver software > Let me pick from a list of device drivers on my computer > Pick your Xoom (either one if there's two shown)
Windows should confirm the driver installed then adb should work in recovery.
I believe ClockworkMod Recovery enables USB debugging anyway, through modifying default.prop
I'd recommend trying the above, and/or if that fails for any reason download Motorola USB Drivers here.

Thanks again but nothing works, I tried rebooting being connected to the PC and the same thing happens, the default recovery from the Xoom stays there, fastboot shows on the command Prompt and in the tablet that everything went ok and the new image was flashed but the rebooting kills it, and I can´t use any ADB commands because of the stupid USB Debugging, if something like this can happen, Motorola should have left it open from default or at least have a fail safe in case something like this could happen. RDS also flashes an image but when it rebbots the whole thing goes to hell, it stays on the damn logo with the same images. I think I can throw the tablet to the trash :crying:

Unless its a serious hardware issue, I wouldn't trash it! It clearly has life as you're able to successfully flash and such.
I'd recommend having a look at the FAQ.

Thanks, but I have done everything, what is the good thing of a successful flash when the tablet returns to it´s previous state as soon as it reboots?
Plus I can´t use one of the most important things, adb, because of the usb debugging, I can´t get into the tablet to activated it, and even if there are recoveries which bypass this thing, I can´t flash them into the tablet, well I can, they just aren´t there after the reboot. And all this because the tablet run out of battery :crying:

ClockworkMod recovery itself allows the use of adb regardless of USB debugging setting.
I believe the command adb remount should allow it.
If adb is denied you can try what I said earlier

The problem lies with the recovery, I only have the default recovery from the xoom, it doesn´t matter how many times I flash it and everything seems to work correctly, when I restart the tablet I get the default recovery. I don´t understand why this happens, command prompt and the tablet in fastboot mode tell me the recovery has been flashed, but to use it I have to reboot and when I do I always find the same good for nothing recovery.

Hello,
I don't really understand your problem with the recovery ?
When you flash a custom recovery with fast boot, you restart the tab and after 2 or 3 second you see the Motorola Logo you push the volume down
and volume up button to enter in the new recovery.
If you flash custom recovery but restart completely the TAB without manually enter in the custom recovery, each time you retrieve the original recovery.

Here is what happens, I flash new recovery, I restart the xoom with power and volume up, when the logo appears, after 3 seconds, I push volume down, recovery option shows, I press volume up and the default recovery is still there, not the new one I just flashed.

Is really no one out there that can help? :crying:

There's nowhere stated that, however I believe you already have unlocked your bootloader, didn't you? Because it's REALLY weird that it can't flash the recovery, I mean, you left the battery run out, then after charging you wasn't able to boot normally again.
I'll think a little, but give a check if your bootloader is really unlocked, the device should have installed the recovery, and as you didn't restart it entirely (let it go after the dual core logo), the recovery should be there...

I have done the fastboot oem unlock command, should I do it everytime? I can´t use adb, because like I said, I never check the USB Debugging, which I have done in my other tablet now, don´t want the same thing to happen twice.

is it dead?

How to install TWRP into the LG P500H from Koodo?

I have a Koodo LG P500H. I am having a very hard time installing TWRP.
Firstly Play store doesn't work. It has this old thing called "Market" that has some apps, but not all. Market eventually gets updated to Playstore, but I can't even find TWRP manager. There was another app in the Playstore that I tried called ROM Manager. It said it installed TWRP for me. I restarted the phone, and nothing happened.
Restarting and Holding power/volume down/home will show a picture that seems to be some sort of recovery mode. But it only run for 1-2 seconds before the phone restarts itself. Nothing happens.
I tried to use ADB. But after rebooting the device it just restarted without ever going into recovery mode. So the flash command just get stuck at "Waiting for Device." Does this phone even have a recovery mode?
This phone doesn't support Odin.
I am used to using TWRP. Without it I cannot flash the phone into new OS.
And every single time I fail, the whole phone seems to have reformatted. So I have to enter in my wifi password and gmail again. All of that typing on a very small keyboard takes a lot of time. I had spent hours on this phone without getting TWRP working.
Please help.

The problem is when I reboot into fastboot (adb reboot bootloader), the phone will go into "phone off battery charging mode". It never actually goes into the bootloader.

Ok I did the following and it seems fastboot and TWRP works now. Be sure to enable USB Debugging on your P500.
1) Fastboot tutorial (I did everything here. I hit "ok" on the LGMDP 1.5 tool as needed. Do not wait till the countdown timer goes to zero.)
http://forum.xda-developers.com/showpost.php?p=15122833&postcount=100)?
FastBoot Tutorial
1. Please download this (or from here) file and unzip it in to any folder.
2. Start LGMDP 1.5 tool with the phone connected (you need to have USB drivers installed) and click on Select Port
3. A separate window should appear like the one below
Just click connect
4. Another window will take shape (LGE Mobile security) with lots of options (links)
Click on the first upper right Browse and select the folder in with you have unzipped the files. You will get some errors that some image, table or headers are missing. Just click OK and in the end everything that should remain selected is Partition Table, APPSBL Image Header and APPSBL Image.
Now just close the window (click on x)
5. Now you are back on the main window and here you'll have to click on Download
6. You are almost done and from now on everything should go on automatically.
NV Backup
Autorestart in Emergency\Download mode and upgrade the files (you selected on step 4)
NV Restore (the last step) Do not disconnect the USB cable until the restore is done
Wait for the phone to restart in normal mode (your current rom).
That should be everything you need to do to get fastboot enabled.

2) Install PdaNet+ (This was the only thing I did in this tutorial. It fixed the usb driver and the fastboot can then communicate with my PC.)

(Note: On top of Partition Table, APPSBL Image Header and APPSBL Image in step 4, I also selected the TWRP image file as my RECOVERY image. Not sure if this make a difference. )
(Note 2: I think you can also get the LG drivers here.)
3) Restart, hold down power + home to boot to the fastboot. Or in ADB type adb reboot bootloader.
4) Open ADB (while phone is still in fastboot mode) and type fastboot flash recovery twrp.img (after downloading the TWRP image, renaming it and moving it to my ADB root folder. I am using TWRP 2.8.0.1 here.)
5) Type fastboot reboot
6) After the phone restarts, type adb reboot recovery. TWRP runs for me. Power+Home+Volume Down (3 button combo) also works now. (Previously this would reset the phone.)

Hey Man, im glad it worked. I could use your help.
I bricked my phone and need the restore file, Do you think you could make a backup from TWRP and upload it?
I would be super grateful.
Thank you.
Here is a zip with CM11, twrp 3.0.2.0 and Gapps for CM11.
Its the best rom I found.

Hi. What is your "brick" like? Does your TWRP still run? If yes you can just copy a custom OS into your Microsd card and install it from your Microsd.
You can also use ADB push to move files from your PC to the phone.

If you TWRP doesn't run, you need to install that first. Do steps 3 and 4 in the above post to boot into bootloader and install TWRP.
3) Restart, hold down power + home to boot to the fastboot. Or in ADB type adb reboot bootloader.
4) Open ADB (while phone is still in fastboot mode) and type fastboot flash recovery twrp.img (after downloading the TWRP image, renaming it and moving it to my ADB root folder. I am using TWRP 2.8.0.1 here.)
