Lenovo TB-8504F - can't get into bootloader mode - Thinkpad Tablet General

I've been on this for the last 3 hours and I'm totally stumped.
My ultimate goal is to get my Tab 4 onto Lineage, so am at the TWRP stage.
My PC can see the tablet, and let's me run "adb devices" and comes back with HGAF9X3E, which is fine.
But, when I do a "adb reboot bootloader" it's supposed to show the Lenovo logo, but just shows FASTBOOT on the screen with a fallen over droid.
I've tried factory resetting from both within Android and the Vol-Up/Power menu. Wiped the cache as well.
In a desperate attempt, I even tried running the Lenovo Rescue and Smart Assistant app to "Rescue" it by installing new firmware, but it keeps failing.

[Q] Boot loop, can't flash?

I got the dreaded boot loop on my I/O edition Galaxy Tab 10.1. From what I recall, it was pretty much fully charged yesterday. This morning, it wouldn't wake up, so I plugged it in. It was dead. Let it charge all day. Tried to boot it up this afternoon and it started looping the Samsung flashy/swirly sequence. When I hold down power to reboot, I get the "entering upload mode. cause: undefined" message.
So... shoot. I searched all over and it seems like the only current solution is to flash it. Which I gather you can do by booting with power+volume down, selecting USB mode and then using adb to reboot into the bootloader. However, adb won't recognize the device now. I've been developing on this tablet for a few weeks; used adb with it tons of times. always worked fine. Now, however, it doesn't recognize it. when i do an "adb devices" it doesnt show up. adb reboot returns "error: device not found"
What do I do now??
UPDATE
I was able to flash with Odin3 using the ROM and instructions here: http://forum.xda-developers.com/showthread.php?t=1083517
So, I can boot into the OS, however, USB does not appear to work so, I can no longer connect via adb (which makes it useless to me as a developer device). Also, the ROM that was included in the aforementioned post is for 10.1v, which is not the same as the I/O ROM. I've found some copies of system.img/boot.img/recovery.img that appear to be from I/O devices (http://droidbasement.com/galaxy/sys-backup/), but since fastboot and adb do not work for my (only Odin3 works) I'm not sure how to flash it back to one of those... Any help would be appreciated...

[Q] Bell D803 constant re-boot

A bit of an SOS situation if anyone knows the right steps please
Well, I restored a Titanium Backup and mistakenly toggled the "restore system apk". It ran fine, all restored and then when I rebooted got stuck.
By "stuck", it re-boots constantly. It shows the LG animation, then all I can see is two messages before it starts booting again:
1) "Unfortunately, Google Play Services Has Stopped"
2) "Unfortunately, System UI has stopped
... and then it does the entire boot sequence, animation, again, and again.
Here is what I can do:
* It is in USB debug mode.
* I have drivers on laptop
* I am able to connect with adb and also shell into phone.
* With adb, I have output to the file an "adb bugreport" as well as an "adb logcat".
* I have several backups:
a) The modemsst1.img and modemsst2.img created by Titanium Backup
b) Titanium backups (full apps and data)
c) an "adb backup - all" backup
* I managed to get it into firmware update mode by pressing the volume up button and the power button and then when it flashed red a few times, just the up button. So, I can get it into Firmware update mode.
Of course, I have never really used adb before, except to dabble a bit. So, I am encouraged that I can somehow get into with shell.
I am not unplugging it until I know what to do!
Since then I have been able to turn the phone off and also put it into charging on USB.
This is what worked:
* Hold down power and volume down button until booting stops and phone turns off completely.​
When it does shut down, I kept buttons down until it flashes logo again and then shuts down again. Then I let go. Phone is off and when I plugged in the charger it shows charging animation.
Now, after inspecting the bugreport, I noticed a lot of these messages for all the system apps like this one:
"I/PackageManager(21318): Expecting better updatd system app for com.lge.sizech"​
I think the cause of all this shralp is this, I did a LG Mobile Support Tool "Upgrade Recovery" and then in Titanium Backup I restored an older backup (incl system apks). At least that makes sense seeing all the "Expecting better apdat system app" messages in the bugreport.
Still not sure what to do next
I tried the very good instructions here:
[Guide] Unroot/Unbrick - flash official factory firmware with LG Launche
http://forum.xda-developers.com/showthread.php?t=2471370
The update succeeded. However, when I rebooted the phone it is in the same boot-loop with message that it was before.
I used the BELL D803B10D_00.kdz file. Now I will try with the earlier version BELL D803BA_00.kdz file.
We will see what happens ...
do you have nandroid backup from previous rom?
I have three backups:
1) Titanium Backup (full)
* This was my first backup performed right after rooting device and installing Titanium Backup.
2) Titanium Backup (full)
* Did this 2 days ago. Device was working OK and did as precaution.
3) ADB BACKUP. I did this one before my Titanium restore.
I restored the first titanium backup and that (ooooppps!) was after I did an LG Firmware update.
ALSO:
I am on Windows 7 64 and although adb works fine, fastboot does not. I understand that might be a problem with windows 7 64.
So, unless anyone objects, I am going to redo on my windows 32 machine and also "fastbook oem unlock".
Since firmware is OK, if I do the fastboot oem unlock, that will wipe everything. But I can still boot and re-setip the phone, right?
Just checking before I fudge everything up here ..
ALSO ALSO:
I had antivirus/theft security installed and I disabled it partway through last restore.
Maybe that has somethng to do with this all .
But I am still cool because I can ADB and also firmware install seems ok.
ADB works and that is the one good sign.

I don't (didn't) have TWRP installed. How can I sideload without it?
Also, should I adb oem unlock to get it wiped at this point?
I'm having a similar problem on a Bell D803. Just happened very randomly today. I turned my phone off for an exam, then turned it back on after.. initially had no signal and a black background. Settings for factory reset wouldn't work. My phone is rooted and has TWRP. I went into recovery and formatted.
Bootloop.
Bootloop.
Bootloop x 20.
I however, don't get the same two messages. I just keep bootlooping.
Got home, tried to go through download mode to unbrick it, but for some reason my computer isn't picking it up. I have all the drivers, and before this incident, it was recognized.
Any solutions?
I'm thinking of buying an OTG USB and then just flashing a stock zip from recovery. Would that be a possible viable solution?

Well, I am able to connect with adb fine on my laptop (Win 7 64) but not on my desktop (Win 7 32)
But on my Win 7 64 I cannot get into fastboot.
I am wondering if the driver install on my desktop went foo-bar and needs reinstall. Also, I noticed that the website drivers are more recent USB drivers than some of the ones linked on this site.
I used adb uninstall package for many user packages and it was success. But I still see the packages listed in the bugreport?
For example: I already uninstalled "com.benhirashima.skiplock" and also "com.lookout".
Why? What to do to really zap them for good?
Sorry, I posted the wrong link earlier.
This was the guide I used which succeeded but made no difference to the boot-loop.

Press the power button down and hold it.
It should turn off, then look like it is turning on, (flash logo very briefly) and then turn off.
Let go of power button and it should stay off.
Do that. Now, does it work to turn off completely?
Let's see if you can do that first.
Then .. do hard reset, exactly like this:

Yup. I totally understand what you are saying and have done it many times. I had to use that method to get into download mode and also had to use it to do hard reset.
I just reflashed the phone all over again a second time succesfully.
Reboots every 5 seconds. Keyboard came up for a few seconds for the first time in 48 hours during the initial setup phase. 5 seconds later as I was trying to input a wifi code it would not appear. then it rebooted as usual.
I really appreciate any input right now. :cyclops::crying:

1) Yes absolutely. It is sitting next to me right now doing nothing at all because I turn it off when I am not trying to fix it, otherwise it keeps rebooting relentlessly.
2) a) Yes, same as the video. b) Yes it says the same exact thing as the video. I press power key twice and it begins. The stock recovery android appears with a loading bar on the bottom for ~1 minute then it goes to the boot "lg animation".
3) Yes it was. Before it was bricked I essentially always had it in debug mode because I successfully rooted it and simply left it on debugging mode after having to activate it to root.
4) D801V11B_00.kdz The EXACT same as the original. This is a Videotron (canadian) phone. I can clearly remember without a doubt going into about phone and this is what it was running before all of this happened.
5) I am having a bit of memory strain here, but I do believe it also said adb devices before any of the issues came. It is a good point I will try "adb device" from another trusted computer.
Other notes: I can browse the android os for a few seconds. Sometimes sound does not work, wifi is non functional (even though the keyboard never appears, I managed to have a security free wifi in my proximity and it would not connect (was saying: temporarily avoiding bad signal)) and also I do have modemstat1.img and modemstat2.img backups for EFS.
adb devices consistently shows "offline" but it is definitely recognizing the phone. I have also tried using usb debugging activated and still "offline". Drivers are up to date and all.
The upper drawer in the usual g2 user interface is strange now. it doesnt have anything except for the date (1970 something...) and a "gear" icon for system settings. I am talking the drawer you drag down from the top of the screen.
This phone was working with absolutely no problems 2 days ago.
Thank you so much for looking into this. I have certainly exhausted my repairing capacities. I am entirely dependent upon the knowledgeable individuals in here from here on out.

Hmmmm..... why your adb devices is not working? But the re-pair works and you can then do hard reset.
But that is good information you shared.
Maybe someone else can chime in.
From my experience:
1) adb usb access seems spotty. My win 7 64 connected fine and it even kept the shell through the reboot cycle. But on my win 7 32 machine it was only detecting device and then not able to shell.
2) I was also able to use from the LG website LG MOBILE SUPPORT TOOLS.
Download the LG MOBILE SUPPORT TOOL
I downloaded the most recent one from the LG website and make sure to select your options >> country and then the correct phone model at the upper right hand corner of the tool.
Then install USB driver for correct phone model.
Then see if USB works, "adb device" should return the device code.
"adb shell" should show the shell prompt.
3) There is always fastboot. But I an noob and know 0% about how to properly connect and use it.
Some others please chime in and help this droid bro!

[Q] Nexus 4 - Stuck in Bootloader, unsuccessful ADB access -

Hi guys,
I had posted a brief thread a couple weeks ago stating that my Nexus 4 restarted by itself, and got stuck in the bootloader animation loop. I couldn't remember whether I had enabled USB debugging in my phone prior to it killing itself (not rooted, completely stock, did the OTA 4.4.3 update just a few days before my phone died, and phone's been out of warranty for quite a while now ).
So I installed the SDK developer tooklit, and followed instructions to set up ADB.
However, everytime I boot my nexus 4 into recovery mode/"safe" mode, I get the following screen ("Screenshot 1" below).
From there, when I boot into recovery mode, I get the following screen ("Screenshot 2").
Every time I connected my phone to my laptop (keep in mind that I cannot start it .. I always plug it in when I'm in "Screenshot 1" mode) and try to used "adb devices", I get the following cmd screen ("CMD ADB Devices" picture below). I've repeated this process and tried plugging the nexus in during various points in different "safe mode" options. Same result: nothing is detected.
So I got frustrated at trying to backup any data from my phone, and just chose the "wipe data/factory reset" option from the nexus recovery mode, and I got this screen ("Screenshot 3"). I've tried this several times, and I keep getting this screen.
So my nexus committed suicide, and I'm totally not sure what to do. I've been trying to learn how to use ADB etc for the past couple of days by scouring through the xda nexus 4 forums, but I'm still very much a n00b. Do you guys have any advice as to what I can do to get my nexus 4 back to a usable state again?
Things I've already tried (in order):
http://forum.xda-developers.com/nexus-4/general/how-to-how-to-flash-factory-image-t2010312
http://forum.xda-developers.com/galaxy-nexus/general/guide-phone-backup-unlock-root-t1420351
I also tried to ADB sideload a stock Nexus 4.4.3 factory image, but it is useless since my device won't even show up in CMD when i enter ADB devices.
However, the problem is that my nexus is never detected in CMD no matter what combination of things I tried, so I can't even do half of the things both of those thread instructions state.
I would greatly appreciate ANY ways to factory reset or flash working firmware on my phone! :highfive:
Edit: I reinstalled Android SDK, and connected my nexus to my laptop after entering fastboot ("safe" mode; volume down + power from phone off state), and I was able to get a slightly better looking CMD window when running ADB Devices command (See "CMD ADB Devices 2" picture). However, same problem as before, where my phone isn't even registering via ADB.
So again, your input would be tremendously appreciated.
If you boot in the bootloader (Volume- and Power) it's normal that you can't use adb. You have to use fastboot in the bootloader.
What is the output of fastboot devices?
Code:
fastboot devices
Have you already tried to flash the factory image or did this fail, too? You have to download the factory image from google, extract it and connect the phone in the bootloader/fastboot mode. Run the flash-all.bat then and it will reflash the stock rom. This will wipe your data, but I guess this shouldn't be a problem for you anymore because you already tried to do a factory reset!
If this worked, boot your phone and if it works fine, I would recommend to relock the bootloader (because it gets unlocked automatically if you flash the factory image and if you don't want to root/modify your phone in any way, your bootloader is usually locked):
Code:
fastboot oem lock
Try it and if there are any other problems or if it doesn't work, just ask again

Fare well bacon

This is to say good bye to my beloved One Plus One bacon.
It started with the clock quitting its service. Suggestion do a factory reset.
I backed up all what TEAMWARE was offering and did the reset. Restored my backup, everything worked well no error messages what so ever.
But the phone didn't boot. The blue android symbol came up and flashed, the phone got hot but no prevail. All attempts to get back into recovery failed. But the phone went into fastboot mode. ADB devices test from a computer isn't finding the phone.
Has anybody any idea? Thanks

If your phone is going in fastboot mode, use 'fastboot devices' to look for the phone after connecting to computer, not 'adb devices'. They are two separate modes/protocols. If you don't have the 'fastboot' executable, google "minimal adb and fastboot" and download it. Hopefully your computer will install drivers automatically.
Once in fastboot mode, and connected and detected properly, just download the "signed fastboot" image from cyngn.com (go to support) and follow steps in item number 8 on this link

I know it's the wrong forum, but....please take a look

I really need the help of one or more of this forums intelligent minds. As I'm sure you'll see, I've posted this in the QA forum, but have had no hits so far....thus the reason for posting here.
So, about 6mos ago, my Nexus 10 stopped working and I couldn't get it back working...eventually moved onto a new tablet, which now I hate....
Anyway, I figured I'd head back to my N10 because I loved it. However, one of the reasons I left it was because it was stuck in bootloop and I was pretty sure it was bricked.
The bad news, I have followed MANY, if not ALL, of the suggestions on getting it back, I just cannot get it to boot. The good news, fastboot connects with the tablet. So, some specifics:
The tablet WILL boot into fastboot and I can send commands and the tablet is unlocked (also, I believe someone said they had issues because they had an older version of ADB and Fastboot. I'm pretty sure I downloaded the 'most current' version 1.4.3). So, with that, I was able to do the fastboot erase functions, such as cache, userdata, system, etc... and then also load the bootloader (mantafm01) and also send the stock .zip file (image-mantaray-....) and the tablet appears to load everything fine. Thumbs up, right? However, when it reboots it stops at the 'erasing' android bot and will not pass that. I left the tablet in that state for a few minutes all the way up to 3 days...no success.
I also tried the above using Wugfresh only to have the same thing occur. So, basically, I am stuck at 'erasing' and I don't know what to do. I feel confident that the tablet has the ability to be brought back to life, I just cannot figure out how/why all of the attempts lead to the same issue.
What I can also tell you is that while fastboot 'sees' the tablet, the tablet does not appear as a device in "My Computer" like it normally did when connecting via USB. I am using the original USB cable and have tried on multiple computers, all to no avail. I've downloaded/installed the drivers, as instructed on many links. Also, while I can get to the 'Recovery Mode' by pressing Power, Volume Up, Volume Down, if I choose "Recovery Mode" on the tablet, it reboots and goes to the 'erasing' screen. I have tried flashing TWRP on the tablet using fastboot as well. And, sometimes, not all the time, the TWRP blue/black screen appears but it will not progress past that screen (i.e., it doesn't go into recovery).
So, if you can, please help. I believe I have followed all of the instructions, but I have to be missing something or not following something correctly. I'm stoked that it looks like it's only soft-bricked, I just can't get it un-bricked.
Thanks in advance! I'm at my wits' end
Try fastbooting a recovery like TWRP thati s updated then flash a rom.
disclaimer: I might be no help at all!
You have fastboot -- go learn all the fastboot commands... you need to know the tools and figure a solution!
erase... hmm? why? What about factory reset? I see you are not using LOS 13 but stock image... need root? Basically, I would factory reset/wipe sdcard, then install recovery (TWRP) [okay, so first you would need to use fastboot to install custom recovery)...THEN, push (fastboot an image.zip (LOS or stock) to sdcards, install, and reboot!
Good to have WUG... another tool in the chest (I have never seen it or used it)
Ok, so one clue is that if your computer cannot see it, that says to me RED FLAG... ADB drivers? but you say fastboot works, hmm... I think this is the problem... Koush's universal ADB drivers? official Google drivers? Could these help!
Erasing screen? Hmm...
I would say, for the hell of it, try flashing different ROMs, Recoveries, and Drivers.... you are basically trying to...
Factory Reset/wipe SDcard [system, cache, ... everything], Flash custom recovery (optional), then, some how (fastboot or mycomputer) get an image on to /sdcard, then, install, then, reboot!
Good luck!

And, sometimes, not all the time, the TWRP blue/black screen appears but it will not progress past that screen (i.e., it doesn't go into recovery).
So, if you can, please help. I believe I have followed all of the instructions, but I have to be missing something or not following something correctly. I'm stoked that it looks like it's only soft-bricked, I just can't get it un-bricked.
Thanks in advance! I'm at my wits' end

Why not try this
I have not had this problem with my Nexus 10 but I did once with my Nexus 7 and it may help you.
Instead of trying to flash TWRP and run it (which is not working for you) why not boot into a temporary copy of TWRP and then work from that? To flash TWRP normally (persuming you had renamed the img file to TWRP which makes it easier) you would enter 'fastboot flash recovery twrp.img'. Instead of doing that type 'fastboot boot twrp.img'. This boots into TRWP and from there you will be able run all the options and from there flash TWRP and other images as normal.
If you are having problems with drivers have you used 'USBDeview' ? Run this as Administrator and delete all references to any phone or tablet USB driver and particularly look for devices with Vendor ID '18d1' or '04e8'. Just select them, right click on them and select 'Uninstall Selected Devices'. When they are all cleared reboot your computer and plug your tablet in and it should install the correct driver.
Another option I used successfully with a Nexus 7 in a boot loop was to connect it while running Linux. I don't have a Linux on a computer so I installed one in 'Oracle VM VirtualBox' I don't know Linux but after Googling for help I installed Peppermint Linux and then ADB for Linux. I downloaded the 'TWP' image into a folder in Linux and any other images I wanted. Connect your tablet to the USB port and then on the top menu in VirtualBox select 'Devices' then 'USB' and tick the option which shows your tablet. I then went into what we call a command prompt in Windows but which they call 'Terminal'. Then type 'ADB devices' and if you see it on the list use ADB instead of fastboot. As I mentioned my Nexus 7 was in a boot loop so I typed 'ADB wait-for-device' and as soon as it looped to a point where ADB could see it then the looping stopped and I could flash the images and recover the tablet.
All the best. I hope you are successful.
As long as you can get into bootloader mode, your good.
NOW
If you can't get into boot loader mode? as far as I know...
You're ****ed.
Unless you want to set up usb boot (might not work on Exynos, idk, this is magic to me) and solder the connectors and flash it like they do in factories. That's next level **** too, and considering an N10 is 100$ on amazon you're better off just grabbing a new one.
