[K1] "Unsupported menu option selected" error & where to get TimmyDean rooted 13-13?
I just got a brand new K1. Fresh out of the box with 3-3 pre-installed, I downloaded and used TimmyDean's permanent root tool, flashing a rooted 2-2 firmware. I then enabled the backdoor and ran all the OTA updates up to 14-14. This took several hours in all. I then ran the BusyBox and SU Tools install script. Everything was looking okay. I selected the choice to exit the script with reboot. The K1 turned off and came back on with the Lenovo logo, but, at the top of the screen was red writing:
Unsupported menu option selected: 1
Unrecoverable bootloader error (0x00000002).
It stops there and goes no further. No bootup.
Attempting to research the error, it seems this is not an error too many people encounter or know about, so my guess is that my only way of fixing this problem is to flash the whole thing over again from the beginning. (Unless someone here knows something about this problem. That would be tremendously helpful.)
Having already experienced what it took to go from 2-2 to 14-14 the first time with the permanent root package, I'd certainly like to shortcut it however possible. In this thread, http://forum.xda-developers.com/showthread.php?t=1404351 , TimmyDean posted a rooted 13-13 that we can start from. However, the link to the download file for it is Multiupload.com, and Multiupload.com does not seem to be up for me. Does anyone know where else I can go to try and download a copy?
I'd have posted directly in that Development thread, but, since I am an XDA noob, the forum system only allows me to post in this General section.
After experimenting with the "permanent root" package several times now, each time ending up with the "Unsupported menu option selected: 1" error after any OTA update, I have to believe there is an incompatibility between the K1 I have and the bootloader files in the "permanent root" package. I do not know if my K1 is recently manufactured and they are now doing something different with them that causes this incompatibility or what, but I felt I should warn you all that flashing the "permanent root" package could cause your K1 to not take official updates or to otherwise brick it with the "unsupported menu option" error. Perhaps the 13-13 package, which I don't have and can't test, didn't have this problem.
My serial number is CB1245XXXX. Manufacture date is "11/11/27."
I have now given up on getting root on my K1 and would just be happy to get it back to a working condition that can take Lenovo's OTA updates without bricking. I am currently trying these instructions and will update as to whether or not that resolves the problem: rootzwiki.com/topic/13877-guide-ideapad-k1-restore-to-mostly-stock-with-ota-updates/ (The forum software will not allow me to post hot links, so copy and paste that to browser.)
The rootzwiki procedure did not work to correct the problem. After any update, the tablet is bricked with the error. There are a few threads on the Lenovo support forum on this issue now, and there is no solution.
forums.lenovo.com/t5/IdeaPad-Slate-Tablets/K1-not-booting-after-update/td-p/548285
forums.lenovo.com/t5/IdeaPad-Slate-Tablets/Unrecoverable-Boot-Loader-Error/td-p/683633
I believe these old bootloader files will not work and will brick newer K1's, so my warning is:
DO NOT ATTEMPT TO ROOT YOUR K1'S. DO NOT CHANGE THE EXISTING BOOTLOADER IN ANY WAY WITH NVFLASH. SOMETHING HAS CHANGED.
This might only apply to more recently manufactured K1's, but, since we do not know when this problem begins, it is not possible to know beforehand whether or not you will brick yours.
To be on the safe side, DO NOT ATTEMPT TO ROOT YOUR K1'S. DO NOT CHANGE THE EXISTING BOOTLOADER IN ANY WAY WITH NVFLASH. SOMETHING HAS CHANGED.
Unfortunately, there was no backup option in the rooting packages, so I could not get a copy of the stock bootloader or any other files, if they are indeed of a different and newer variety. If someone has a recently manufactured K1, perhaps you can get those files and share them, because a lot of people are starting to see this problem now.
I have one with sn#1250xxxx, mfg dt 11/11/29. I wasn't even trying to root the thing. I happened during an OTA update. I tried probably all the recovery/rooting option out there. None of them worked. I have the tablet booting at lenovo screen. But I think you are right about the bootloader. If we can get the correct bootloader, we might be able to the the tablet back to life.
fix?
Has anyone come out with the fix for your issue.. I have the same issue . Used TImmy Dean's method.. and anything updating past the 02_02 (loaded from the tool I get the error... Anyone here have access to contact JimmyDean to ask him for help?
I see that he updated the tool to K1_A301_13_13_111209_US and maybe K1_A301_14_14_111209_US but all the links are dead.. anyone have a good place to download the files?
Try out the downloads on the following Lenovo's link -
download.lenovo.com/slates/k1/OTA
those are just OTs.. not image files.. If you don't have a compatable boot loader, you can't load those files.. We don't have a compatable bootloader.. so this is why we need ver 13 of timmy dean..

Can someone who's getting this bootloader error send me a pm. I put together a stock 120109 update that may work around the issue and I need someone to test.
Was this issue ever resolved, I didnt attempt to root mine, only attempted to wipe it clean and got this..
No, no real resolution. What I ended up doing was NVFlashing one of khanning's ROMs, like this one: http://forum.xda-developers.com/showthread.php?t=1560441
I don't know what's going to happen when I have to update again, such as the upcoming Ice Cream Sandwich update promised by Lenovo.
Tab boots to "welcome" screen but does not register touches, leaving me unable to move forward. Ready for the long story?
I am helping a friend who bought this tab from a third party. When he received it, the previous owner stated that they did a factory reset back to Honeycomb but he noticed that it did in fact still have ICS on it. Probably OTA'd when the previous owner did the reset. Tab worked fine for about two weeks until one day he came home and the lockscreen would not register touches. That's where I come in.
I did the "erase, wipe" (booting while switching the screen rotation back and forth.) Tab wiped and brought me to the "Welcome" screen where you select country and language and still does not register touches. I have tried blackthund3r's flash and manager tools, as well as multiple guides to recover from what I have seen referred to as "flu." The main problem I have is that I cannot get a valid UID. Using USBDeview gives me an 11 digit serial but it returns as invalid when plugged into DotNetDetector and I am unable to use SDB because the non working touchscreen has left me unable to enable USB debugging.
Any suggestions, help, advice, on things I can try? I am really stumped and would like to help my friend/conquer this problem. Thanks for anyone who has taken the time to read this/offer help.

Get ready for some Ubuntu... Here is the guide that will get you a valid sbk. My nephew just brought his tab to me after forgetting his password. So I was in the same boat as far as UID/SBK. This is gonna take a while so put some time aside.

As sure as I am reading yoru reply the damn thing just started working. I was able to get to USB debugging and via ADB I was able to pull the UID; which was the same as the one I got from USBDeview btw. Still an 11 digit code. The only thing I can guess is that it has a faulty touchscreen, or maybe the battery was just too low to register touches? Thanks for your reply though. Always nice to be able to rely on the folks at XDA.
That is too cool. The other way is a learning experience to be sure. Enjoy.

I have now realized that the touchscreen does work but is very glitchy and have found that lots of people have had problems with the OTA ICS update. Any suggestions on a good custom ROM for this tab? It isn't mine so I have not been following this section. Would like something close to stock ICS but with fixes that resolve the problems associated with OTA.

First check in Settings>About Tablet>Build Version - this will tell you what rom you are currently running -
Then, if you can, download and install Acer Recovery Installer
This tells you what bootloader and recovery is installed.
The glitches you speak of and the 11 digit uid point to an ICS Rom and unpatched HC bootloader - updating to the new BL often fixes these weird glitches BUT if you flash a custom rom as well, you'll be running sweet!!!
If you wanna stay close to Stock then I'd recommend ezterrys one here comes pre-rooted and busy box installed - and if you want to you can install his Over clocked kernel too.... plus its well maintained and supported
there are many tools and guides around to help you...the ones in my sig for instance the cpuid one has a lot of general info in it too re bootloaders, sbk and flash tools.
If you have any q just ask, there's always someone round willing to help...good luck!!
hi all and thanks for your help in advance...
i have been assigned an a500 which is bricked and only shows the acer logo and nothing goes on from there
i have tried multiple roms along with custom roms as an update.zip into an SD card but it stops at the same position which is about 30% everytime on every rom
ive tried fastboot, says the BL is locked and when i tell it to unlock it it just says OKAY and stays locked
now blackthund3r with his apx flashing tool presented some hope as it detected the apx mode but after the flashing starts it wont go into bootloader mode the screen is just black
i have attached a screenshot of my pc trying to identify the tablet with apx not installed for no driver is found
i have installed every driver i can put my hands on starting with the latest from Acer drivers and none of them seems to give me the apx driver.
i think the only problem i have is the apx driver, can anyone point me in the right direction? ive got my SBK from afterota only one time and it never worked after that time. can anyone help with the drivers?
#edit:
i forgot to mention that even though it says apx is not installed, when i connect it in apx mode i have a little usb icon which says "eject APX" call me crazy but that just says apx IS installed right?

Generally, the APX (boot recovery download) driver should be installed with just the normal Acer drivers from the web site. On a Win8 pc, it can be a real pain, so if you have a Win7 pc, I would advise it. I suppose you are looking in Windows "Device Manager"?
Not sure about the "eject APX" message. Sounds strange to me, but maybe it says that on an XP PC, been to long to remember.
Stock Acer bootloader has no "Fastboot" capability. This was added after ICS with a patched bootloader.
Either way, you will need your CPUID number to use any of the NVFlash tools. There are stickies on how to get this, but more than likely you will need a Linux set-up, not sure if there's a windows method.
If the tab had been rooted, and a custom recovery added, there's a possibility there was a backup done, and it would be in the Clockwork Mod folder on externalSD card.

I am running win7 x64 and the apx drivers seem to be installed as blackthund3r recognizes it, its just that in blackthund3r apx tool it never seems to want to get into the bootloader mode i have no idea why.
also regarding my CPUID when i used afterota it showed me :
Tablet Serial : 485FEFA483118011
Tablet Cpuid : EMULATOR-5554
Tablet Sbk : 0xF5030000 0x00000000 0xF0D1E302 0xF0D1E302
Android Build : GT-N7000-user
Bootloader : 0.03.01-HC
now isnt the CPUID a 15-16 digit hex number?
and if my CPUID is wrong in this case above it should mean my SBK is wrong aswell right?
the build number is of a galaxy Note device which is also strange.
also, the device came with no SD card and it has not been rooted or a custom recovery installed on it, the owner says "it just died"
I had the Linux idea in mind as a last resort i suppose its time.
thank you for your help

Oh man, Somebody must have tried installing a Galaxy Note Rom? Got me a little confused on just exactly what you have there mate.
The CPUID as you stated, should be an alpha numeric sequence such as for example (mine)038061c7409fa617.
Why it's telling you it's Emulator-5554 is quite strange. Tell me, how exactly did you get this CPUID? As if the tablet won't boot past the bootloader (Acer screen), then the usual discovery tools we have, can't get it, and this I can promise. I'm guessing it's just spitting out some programming error.
And, I can also say your SBK number is suspect also. Looks weird. Here is mine (no, won't work on yours) 0x79531F00 0xBB680C01 0xFB22E803 0x8ADE2003
I would suggest the following;
There's a user here, dibb_nz, and he has some links on unbricking. Currently he is abroad, so won't answer PM. Also, there is a thread "Why CPUID is Important (might be the same things). In there, are some steps on how to get the number from a dead tablet. No, I've never personally had to do this, but other folks have. I know there's steps from Linux, but believe there may also be windows steps as well.
Another good link from Linux (you can run I dual boot, as I do) http://forum.xda-developers.com/showthread.php?t=1751978 This should be easy to follow, and probably best chance at getting it.
Another good thread from Dibb_nz http://forum.xda-developers.com/showthread.php?t=2049778 Has several unbrick procedures.
I have several factory Roms here on my server. I try getting one whenever I come across them. Acer in all of their infinate wisdom, have shut down their OTA servers for quite some time, and also, they add and delete factory Roms from their official support site all the time.
If I can help you, I will. Some things may be out of my control, but will help as much as possible. We have some pretty good folks here in the 500 forums, but the tablet is getting a bit old, and most have moved on to somehing newer.

I got my CPUID from afterota "no idea how but it just worked for one time, and later yesterday worked again".
when i try "adb devices" it just shows nothing, while yesterday also i tried the same command and it returned with EMULATOR-5554 as a device connected and i could get in the shell but could do nothing from there...
i have seen those posts before they have been helpful but as far as using "a500 manager tool" to recover my CPUID, the tool hasent worked.
anyways i suspect the only way of getting my CPUID is through a linux distribution,and from there i can stumble around with nvflash from there or go back to windows. As I dont have any linux expertise it would be a good experience.

Use Ubuntu for the linux distro. It's by far the most common. Basically you can install it 2 ways.
1) As a dual boot (might have to disable a BIOS setting if your PC is pretty new. Usually only if it was a Win8 new system) Benefit is that the Linux OS will get 100% system resources. Downside is that it'll partition your HDD.
2) Run it under cygwin. Basically an emulator which runs within windows, and you create a virtual drive for the Linux install. The benefit is that you can uninstall it rather easily when finished. Downside is it shares Windows resources.
If you're only after the UID, then probably the cygwin method is better for you.

i've never heard of cygwin, i was thinking virtual machine but i was slacking due to the work it needs doing and my impatience... i must ask if afterota is showing EMULATOR-5554 and i managed to get it in adb mode and it still showed EMULATOR-5554 do you think its even recoverable in ubuntu?

Well, being in the 500 forums, and owning a 501, I can say these tablets are pretty much bulletproof. I've never known one that can't be unbricked. Basically, if it has some life, it can be brought back. Mine blew away the bootloader, hard bricked. Took out the mainboard, slapped it in the oven, reseated some nand chips, and it updated the blob file when I booted it. :good: imagine that!
It's still a little flakey running EUUS files, but it's on 3.2.1 and rooted, so I will leave it on that rather than press the issue any further. Besides, it's only used for You Tube and Browser anyhow.
I would say the Linux method will probably reveal the true CPUID. Afterota seems like it's generating some development code. Like I said, none of those tools will work properly unless the tablet OS is running, so who knows what strange things will happen.
I've never used VM, but it should also boot ubuntu.
This chap just got his CPUID today using a Linux distro.

the oven? im confused what reflowing the solder has to do with anything lol and i hope im not going to that stage haha
im downloading ubuntu now as we speak, im hoping it will work but im confused about the libraries that i need to download, GCC and the other ones, are they something special and special installation required? or sniffing around google would do the trick?

Well, normally after you get an ubuntu install, you can download extra packages. Terminal for one. I'm sure the Ubuntu help center tells you how to get certain packages (lib's and such). Basically you do it via a terminal window. Like I said, I've never used that particular procedure myself, but seems some others got it figured out.
Ha Ha... the oven. Yes, I was skeptical to say the least, but thinking back on rice to dry out a phone, putting a dead HDD in the freezer, well, it seemed plausible. And for me, the oven trick worked. Pressed all the nands back into place, and was able to clear the "Blob update failed" error (was stuck with no working bootloader, hence a hard brick). I attribute it to my 2.5yrs old girl dropping the tab once too often (although was in a good cover).

Eh, ok, you got the CPUID. Hang on and I'll give you a link for Timmy Deans 3.2.1 rollback.... Sounds like you got a corrupt partition.
OK, download and unzip the contents.
http://www.mediafire.com/download/fo4wqjeald4s3rj/tdv4_rollback_rom.7z
Now, in the contents, you will see the file pbj20upgrage.exe
Run it as "administrator" (right mouse click it and select run as administrator)
Now, don't plug in the tab. After it does a couple things, (installs drivers, starts looking for current build it will eventually prompt you to start your tab in APX mode. Do it. Then connect, enter your CPUID when asked, and it will NVFlash a complete pre-rooted 3.2.1 with CWM Recovery.

OK, download and unzip the contents.
http://www.mediafire.com/download/fo4wqjeald4s3rj/tdv4_rollback_rom.7z
Now, in the contents, you will see the file pbj20upgrage.exe
Run it as "administrator" (right mouse click it and select run as administrator)
Now, don't plug in the tab. After it does a couple things, (installs drivers, starts looking for current build it will eventually prompt you to start your tab in APX mode. Do it. Then connect, enter your CPUID when asked, and it will NVFlash a complete pre-rooted 3.2.1 with CWM Recovery.

Great!
Now, just remember, when you install one of the full ICS Update files (I have a thread stickied in one of these forums), it will change the bootloader, and also do away with the CWM custom recovery. A custom ICS ROM will not run on an HC 3.2.1 bootloader. This is why we had the Blackthunder tool and patched V8 bootloader. Just so you are aware.
Good luck!

Welcome to the world of corrupted nand memory.
You can try running "babsector" and see if it will NVFLASH repaired partitions.

Not saying it will fix it, but it might.

Hi all,
Thinking about this phone, what is bootloader like, unlockable? Can fastboot be accessed?
Looked all over for info, most Chinese forums are bashing the phone, but the reason is not clear to me (seems mostly joking that it is just a knock off of the Nexus they produced). Chinese is not my first language, that is probably most of the problem.
I am interested in getting some development going on here, but I need to know if it is worth the trouble even trying. Huawei does release source, but it is really not easy to find. Also, source for this phone seems to not be released yet. If you google "huawei open source" you get some sources, but not for this device. If anyone can point me in a better direction I would appreciate it.
I followed step 1 of this guide: http://forum.xda-developers.com/showthread.php?p=68280798 to get my bootloader unlock code.
I haven't been able to find a version of TWRP for this phone yet and KingoRoot hasn't been able to achieve root either ?

You might try this for root: http://www.huaweishuaji.com/112.html
Supports many other Huawei devices, but I cannot guarantee as I have never used it, so use at your own risk. There are also some Chinese guides for unbricking out there. It involves putting the stock image onto the external SD card and running a flash from the phone. Seems it would be fairly easy to build TWRP for the the device if there was a little more info about it, such as partitions. Unfortunately, I do not have the device and need to upgrade my PC before I can start building anything again.
Bored today, so been digging. Seems it would be fairly easy to port the zenfone 3 twrp over, as the specs are similar.
I can't try to build as I need to upgrade, and don't have the phone to test anyway.
Here is the git, looks like only a few changes to make: https://github.com/shakalaca/android_device_asus_ze520kl
Here is a link with how to flash the zenfone: http://www.asus-zenfone.com/2016/10/how-to-root-asus-zenfone-3-ze520kl-and.html
If it was me I would give it a go booting the z017d one, but make sure you "fastboot boot filename.img" and not flash. I would take the risk, but not saying anyone else should.
Not going to have anything to build with until around Christmas, so hopefully someone can give it a go building for the phone. I might get the phone around Christmas too, lets see how development goes.
can anyone try to load the twrp from p9 lite? The hardware specs are just as much the same
"fastboot boot recovery recovery_twrp.img"
maybe it works...
It's a no go booting either of those recoveries. Each flash while successful, ends in a boot loop.
I also don't have the time right now to dedicate to build TWRP from source.

Mine was bricked after trying the KingoRoot. Any chance I can unbrick it somehow?
P/S: Yes I am an idjit because I didn't make any kind of backup. :crying::crying:
Seems the Huawei unlock code generator is down. I entered my phones data, but the unlock code never appears. I only get an error message when I enter wrong data (i.e., CAN-L11 instead of HUAWEI CAN-L11), so seems the data is validated. When did you create your code, @wangdaning?
Regards,
sebastian
Don't have the phone, I think an earlier poster did get an unlock. I was speculating about what might be possible.

Sorry, my fault. thisisMZ1 was the lucky guy with the unlock code.
@thisisMZ1: did you try to boot the image without flashing it first? Don´t know if that makes a difference, but one never knows.
For the unlock code, I got an unhelpful reply from the support team ("please use the form provided on..."). My replies on this haven´t been answered yet, so I´m waiting... Will keep you updated.

Hi again,
I managed to unlock the bootloader: I created the Huawei ID on the wron (Asian) website. I created a new ID via the German website and was able to use the website for unlocking code with the new ID.

Wonder if it is only for the nova and not the nova plus. I did not make it and have neither phone to test, just passing it along. Unfortunately, they seem to have not used github.
Does anyone have a link to the factory recovery.img?
I flashed the Recovery to the Nova (not the plus) and I got exactly the same error. If I try to flash the superSU, I got a error that it couldnt Mount data and after a Reboot the root doesnt work.
I guess their could be several variants of the phone, which does not bod well for hopes of development.
Something new?
The chinese recovery boots but has problems to mount the partitions.... Its for the CAN-L01 and on my CAN-L11 is a different fstab. I have not the skills to compile a working one.
Hi everyone,
I just updated my Asus Zenpad 10 (Z300M) via OTA.
The tablet booted and I saw the Lock screen. But after a couple of second it reboot.
I've tried a factory reset. BU it's the same probleme: It boot up to the "first start" prompt, and after a couple of second reboot.
I tried to install a custom recovery to flash a new rom with SP-Flash Tool (following this post nstalling TWRP and rooting Asus Zenpad 10 (Z300m))
But I got an error when I readBack.
And even if I flash the recovery, I can't access it on the tablet. I got a message "Your device has failed verification and may not work properly" when I try to go to recovery
Can you help me with this ?
Thank you
Same problem. When WiFi is ON.
When I put WiFi OFF - the tablet works fine.
Last firmware doesn't help, reset too. I think there is no solution at this moment, except maybe to flash an old firmware with Android 6.
I'll replace it in store. No idea about Asus control quality of their firmware... but this problem is pretty common.
???

What I do not understand! Purchased this tablet due to the thread you mention on here for TWRP using the SP Flash Tool 5.132, right? I just went ahead and used the SP Flash Tool version been using and got that individual error right at the end so did NOT try flashing the recovery! He was very talkative B4 getting this tablet but now after speaking of errors, no responses.....? The version SPFL he says is the only one that works, its option.ini file DOES NOT have the READBACK part in it for changing from false to true...... the very next versions of SPFT after do.....
any ideas????

Bro, are you serious? I don't reply to your messages for a few hours so you call that whole recovery/rooting thread some kind of a scam or conspiracy? (This is not my day job btw.) The error messages you are talking about are a result of you rushing into this thing and not doing your homework, skimming the directions and/or failing to use common sense. Of course SPFT 5.1532 does not have the read-by-partition option. That's why we use a later version for that. Exactly as it says in the OP. And if you were to do your homework, you would find out that the "..failed verification.." and/or "...different operating system.." messages are expected because of verified boot process built into the bootloader.
I'll give you that

The link on the Z380M is what threw a flag for me because that Asus tab isnt rootable. If this is some combo of slipups between tools & devices that lines up just right to get TWRP on its not described very well in the OP. Using the 5.132 (?) you can not readback with that option.ini file.... so what am I missing? The bootloader unlock app isn't written for this tablet is it? written for the zenphone 2 (3)?
Wow, I'm not sure if you're trolling at this point or what. If your ASUS ZenPad 10 Z300M tablet is not rootable, then you are the first one to report such a device on XDA. You still keep saying you can't readback with SPFT "5.132". I hate to sound pedantic, but I think it's better if I make my reply in list form.
There is no 5.132. The recommended version is 5.1532.
SP Flash Tool version 5.1532 does not have the "ShowByScatter" feature at all, as I've told you at least twice.
You can read back any part of the flash ROM by specifying the range manually in 5.1532 or other versions.
You can read back by partitions specified in the scatter file by enabling "ShowByScatter" with SPFT 5.1548 or higher only.
You can flash to this device by using SPFT 5.1532 only (and a couple of older versions).
As for the guide not being clear
I did not write that guide. That is @justshaun's post. I only wrote one section of it and made some corrections to other parts.
Yes, you might encounter some stumbling blocks when blindly following the steps without knowing why you are doing them. But this is a good thing, to be honest. Because if you don't understand even a little bit about what you're doing, and are not able to solve those types of problems, then you have not crossed the pretty low bar for safely modifying your device. In that case, I think you're better off not bothering with this whole recovery/root thing. It's for your device's safety.
All of the problems that you're having have probably been discussed in one thread or the other.
As for the bootloader unlocker
I have never used the unlock tool.
It does not work sometimes, maybe even most of the time.
ASUS has removed the link to it from their download page
Take it up with ASUS if you want to make it work.
Just want to mention for anyone else struggling with this issue, what fixed it for me:
I found the reboot would only happen when wifi was turned on, and even more weird, it would only happen when connected to specific wifi networks. After doing a factory reset I was able to set it up again by tethering to the wifi on my phone. I then found that I actually was able to connect to the problematic wifi network but only by setting a static IP! This has completely resolved the issue for me.

I have downloaded everything in the OP again and will attempt to get twrp on tablet again. I did notice one item that was causing my problem that you could call a newbie f/u... I'm using a new browser that has adblock builtin & on by default and it was causing the "loop" when trying to download the recommended SP Flash tools. I got the ones from the link downloaded and they have more internal components like the newer SP Flash Tool versions....... My bad.
Will go through the steps again hopefully later today, my apologies man.
