[Completed] [Q] Installing Android Lollipop on a unknown tablet. - XDA Assist

Hello! This is my first post on this forum, but I'll try to be helpful.
Well, I got my hands on a tablet. Which tablet? I have no idea. The "About page" on the settings only says that the Model number is M1706. And nothing else. (Besides that it's running on Android 4.2.2)
Since Android Lollipop is out, I've been dying to try it. Unfortunately, I don't have a device that supports it, so I though I'd try to install it on this random tablet that I have.
And here's where the problems start.
I tried flashing a AOSP Lollipop build to the tablet, but it always aborted. (From this thread)
Then I tried to install a custom recovery to see if that would help.
Managed to find the TWRP apk and install it. Unfortunately the app crashes when I open it.
So I tried downloading it from the App Store. The thing is that my tablet doesn't have the App Store app.
I tried many different versions, but none of them were able to be opened. It's like a process was killing the app, I think. I have no idea, though.
I then installed Clockworkmod ROM Manager to see if that would work.
It installed and opened, but it can't flash ROMS unless my tabled is rooted.
Since this is a mistery tablet, I don't think there are any root methods for it.
That's my situation right now.
Any suggestions on what I can do to achieve my goal of installing Android Lollipop on my tablet?

Hi,
I have to say, you're swimming in dangerous waters here.... And so far you've been extremely lucky. You can't flash anything to just about any device, unless it's made specifically for your device. Many times trying to do so can brick (destroy) your device.
So you'd be best to stop trying to install things made for other devices.
As far as your device getting Lollipop, that seems doubtful. I say that because it's on Jelly Bean.... Not even kit Kat. Of course that's an educated guess though. And until you find out what actual device you have, There's not much we can do for you. Also, you won't know if there's anything out there for your device... Cause you don't know what device you have.
I'd work on solving that mystery... And go from there. ?
Good luck.

Eyyup. I know what I'm doing is very dangerous, but this tablet is basically useless without any form of Google apps. Besides, I think it's a prototype tablet, so even if I brick it, I won't be sad. I got it for free, after all.
I'm trying my best to figure out which device it is. Usually when you have Google apps in a device, Google Play store shows its type when you install an app using Google Play Store on a desktop. Since I can't get Google Play Store in it, though, it may be a lot harder. I still need to try installing Google+ to see if it works. Will come back with the results in a bit.

Lenovo IdeaTab A2107A-F

I am starting this thread to hopefully encourage discussion on the Lenovo A2107A-F tablet variant.
I am aware there is an existing thread on the A2107 here:
http://forum.xda-developers.com/showthread.php?t=1982334
but that thread is concentrating on the A-H (dual sim + wifi) variant which is somewhat different from the A-F (wifi only).
So far I have not found any custom rom development, which is disappointing as the stock rom leaves a lot to be desired IMHO. While the current OTA update is fine for web surfing, reading emails etc, HD video playback (particularly YouTube HD) is very poor. Also the recent OTA update forces an optimization of apps on bootup which leads to long boot times
You can root and install CWM by following steps 1-5 from the 1st post here:
http://forum.xda-developers.com/showthread.php?t=2044496
Note that "-Update 3-" mentioned in the post does not appear to work for the A-F model!
So, has anybody any leads on possible development on this tab?
Any tips on improving performance?
My first tip:
If after installing CWM you cannot get to the CWM recovery screen after powering down the device, look for for the file "/system/reboot-from-recovery.p". If it's there, either delete it or move it to some other place. This file restores the default recovery on a system reboot.
I got bitten by this a couple of times
Thanks for starting a separate thread for the A2107A-F. I'm new to Android devices and just got this one two weeks ago. I'd like to get rid of several of the apps that I have no use for and from what I understand that means I have to root it. I got lost in the details of the other thread, but I tried reading all of it. I'm on Vista and somewhere along the line I installed one of the suggested ADB drivers via PDAnet. Device Manager is showing Android Phone and under that Android ADB Interface. I wasn't sure if that matched closely enough with the step-by-step threads since I don't really think of the device as a phone, so I've been holding off on going further. I've tried using a few other drivers that were suggested in the large thread and some other threads, but Vista always tells me the current driver is the most up-to-date one.
Do you know if it's okay for it to say Android Phone rather than something else?
Thanks. I've got some other questions about the specifics of some of the other steps, but this is probably enough to get started.
My apologies in advance if my posts are too long and my questions are too basic for these forums. Feel free to point me somewhere else based on what I'm asking for. I'd honestly appreciate any leads towards my goal of getting rid of the bloat on this device and making it more responsive. (Wow! The portrait to landscape lag is really bugging me now after reading around here).
Anyway, my primary purpose is to remove the seemingly unneeded programs, services and widgets that come with the tablet. Maybe I'm just ignorant about these things, but at this time things like messaging (IMO), mapping, and some of the other default features are of no use to me. They seem to be eating up a lot of resources. I can kill some of the services I think they are associated with, but they keep popping back up.
I did watch the "noob" video (color me a tiny ant to be squashed) and did try to search for an answer to get me even started. I've read the huge main A2107A thread (80+ pages) and tried three of the suggested ADB drivers with my Vista 32 setup for my A2107A-F. The only one that even seemed to connect was ADPnet and it showed the tablet as a Android Phone. Maybe I'm just too paranoid, but after the multiple "brick" posts I'd like to make sure I'm on the right path before trying to "root" the device which appears to be the first step in removing all the extra stuff Lenovo added.
Not that it matters, but I've had the tablet for almost two weeks now and my favorite things are Slacker Radio, Scrabble, Roll It and Zen pinball. I do play Words with Friends with my wife, but I don't like it since some of the words they allow are not valid in Scrabble (which I used to play as an expert competitively face-to-face).
If you are so inclined, feel free to PM me for a Scrabble game. I promise I will not use anything other than my brain and the built in dictionary to make my plays. (I'm a bit rusty since I gave up competitive Scrabble in 2006).
So, long story short... Thanks in advance for any and all advice you can give on slimming down the Lenovo A2107A-F. And if you want an honest Scrabble challenge feel free to PM me.
As far as checking if your drivers are installed properly I would open a dos (command) prompt in window and from within the window change to the directory where you have the 4.03root files. From the command prompt type 'abd.exe shell' and you should see something like "[email protected]:/ $". If you don't see this then you will not be able to root! You need to make that USB debugging is turned on on your device you have an entry in the device manager for ADB Interface (expand on the device which you have showing up).
I am no expert, and I struggled with this on my first go also
Once rooted you can then install Titanium Backup from the play store and use it to get rid of the bloatware! Proceed with caution however as it is possible to remove critical system apps!

Thanks! That's the type of test suggestion I was looking for to make sure I was on the right path with the driver.
So has anyone tried creating a rom for this tab yet? I've been doing some research into porting another rom to work on the A2107A-F, but want to make sure there isn't one already.
I just received a notification of a new firmware update for the A2107A-F. This would be the second available update.
Has anyone else gotten this and taken the plunge yet? I'm curious if this is possibly Jellybean, as some of the larger screen IdeaTab models run this.

I lost root after applying the first update a while back. That's typical when updating. Afterward, I was able to re-root mine again using the same procedure as before. All was well. So, don't panic...yet.
Can you report on what other changes the update made? Is it Jellybean? Or maybe ICS 4.04?

Well, I just re-rooted my tablet and everything was successful! There is absolutely no difference AT ALL with that so called "update".

Although I have my A2107A rooted and tweaked to my satisfaction, there are a few lingering issues that I'd hoped an update would correct:
1) The neutered Bluetooth stack. The tablet is supposed to work with Bluetooth keyboards, mice, etc. It doesn't. Although I've gotten it to talk to an external GPS module, other Bluetooth data connections simply will not work. Oh, and Bluetooth audio? Forget about it!
2) Some settings that are present in stock ICS builds are just omitted in this one. As an example, the ability to specify a default TTS voice. It's present under settings in my wife's tablet and every other ICS build I've ever encountered. Not this one!

I was rooted too, lost root access (only with some apps!) after the 130221 update Feb 28. I'll try the same root procedure as before to see if I can get it back. Glad to see a thread on the popular US version A2107A-F. Maybe someone will port Jelly Bean to this tablet! Doesn't appear Lenovo wants to do it...

I cannot get this 'update' to install after downloading. The tablet reboots to CWM during the install (I am rooted with CWM installed) and when I attempt to manually select the update.zip from /sdcard/googleota/ I get on error (status 7). In desperation I re-loaded the stock rom that I found on another thread and when the tablet attempts to update I get a "assert failed apply_patch_check( /system/app/applicationsprovider.apk)" error Anybody any ideas?

I'm in exactly the same boat as you. I'm getting the same exact error. except that I do not have CWM installed (I am rooted though). Perhaps there's a problem with the update.zip?
Something odd that I noticed however: After the tablet reboots into recovery mode, the update fails, and I go to browse for the update.zip, the sdcard/googleota directory is missing (along with everything that follows it alphabetically). They reappear upon normal boot. I've tried copying it to a directory closer to the beginning of the alphabet and it does show up while in recovery mode. But it still will not install.
Maybe I somehow do not have the available space to perform the update? Is that possible? I show plenty of available space on both sdcards. Could we somehow be below a certain ROM space threshold necessary for an update?
I think in my case because I loaded a 'stock' rom I got from another thread, this rom is failing a verification test the update is doing before install. I do not know how to get around this! I'm continuing my search, but I am not so confident this will be resolved easily...

Well, I am running a stock rom. I am unwilling to "mess with success" until there's a 100% reproducible way of recovering if it fails. And, so far, everything I've read in the other A2107A thread has been hit or miss for the A2107A-F people.
Anyway, If the update is performing a verification test, then it my "virgin stock ROM" should certainly pass it. The only thing that I did is to root it. Hmmm...could the update be testing for that and refusing to install if it detects a rooted device? I would tend to doubt that, since the previous ota update went just fine. I lost root in the process but easily reapplied it afterward.
Thoughts?
Interestingly, I flashed the A2107A-F_S483_121115 rom (again, found in another thread) as I was having verification problems with the OTA update just released from lenovo which was available from the A2107A-F_S484_121211 flashed rom. While the S483_121115 rom appears to be older, I no longer get the option to update via OTA as the tablet is telling me that my s/w is up to date! Go figure.
It's really too bad this device hasn't taken off. If I actually knew how to dev then I would start developng ROMs for it. I'm enjoying it now that I have root and got rid of bloat.
Hey guys. Just wanted to say if someone can send me a stock rom and be willing to test, I'll try to do up a good rom for the -f models. I'd use mine for the stock rom, but I've edited a lot of the system, so no go there. If you have the stock rom or want to be a tester, let me know.

[Q] Help downgrading to CyanogenMod 10

Using CM11 has been a disaster. Processes keep shutting down, the phone spontaneously restarts, and features seize up until I restart. I didn't upgrade it myself, so I don't know much about this process. I'd appreciate it if someone could help me get back to CM10. This phone is not officially supported, so I'm guessing that's why the guys at the CM forum haven't responded.
I have a Huawei Ascend Y300-151 with Android 4.4.4.
Of course, if someone thinks that my phone should work fine with CM11, and can suggest how to make that happen, that'd be just fine, too.

did you installed cm from here http://getcm.thebronasium.com/?device=u8833?
303
I didn't install it at all. This is just how I got the phone. I can tell you that it's CyanogenMod version 11-20141114-NIGHTLY-u8833
That could be the problem. You never know what the previous owner did or what they flashed could be a bad download, the wrong firmware, etc. Best to get back to stock and start over so you know exactly what has been done.
Hmm... probably. Right now going back to the stock ROM would be an improvement. Could I get some help with that, then? I haven't been able to find clear steps to do that with my specific phone, and when I went to Huawei's web site, I couldn't find the ROM for the Y300-151 and wasn't confident the Y300-100 was suitable.
I've used CM11, but I'm not familiar with that phone, so unfortunately I can't help with that specifically. There should be plenty of help on XDA. Just search for that specific model. Sometimes it takes a while to find what you need, but I'm sure its there. If it's done right CM11 has never let me down.
I'm sure CM11 works fine for most people, but my instincts tell me that my phone is underpowered for it. Ok, I'll look elsewhere or start a new thread about getting back to the factory ROM.
Yes, first thing to do is get back to stock. But don't give up on CM11. It should work fine on underpowered phones. It's just a slightly modified version of vanilla android which is a fairly light ROM.
I hope you figure it out.
Good luck!
If what you say is true, then I expect I'll be right back here again. I doubt that the wrong binary was used--I dunno, maybe something was wrong w/the installation procedure, but I'm sure the right binary was downloaded. In which case, maybe I should be attacking these problems directly, since I'm having trouble getting support for installing the factory ROM.

[Completed] How do I unbrick my phone?

First of all, I'd like to say that I know very little about how Android, electronics or mobile phones work in general, so everything I've done has been from internet tutorials. Please don't use any jargon as I probably won't know what you mean. ELI5.
A few days ago, I tried to root my phone and it didn't work. As a result the phone went into a boot loop and I didn't know how to fix it. The long and short of it was that I ended up flashing the stock firmware onto my phone and basically doing a complete factory reset. After some time trying this I managed to get the phone to start up and I was able to access the interface and all that. Unfortunately, my WiFi wasn't working (the button would simply turn off whenever I turned it on) so I had no way to download the most recent updates or apps or anything like that. After following several tutorials on how to fix this, such as flashing the modems and bootloader, I still wasn't having any luck. So I tried something that proved to cause even more problems - I tried to install a new kernel. Now my phone won't even boot past the logo. I probably didn't install the right one, but what can I say, it's not very clear which one I need.
Now I'd like to point out that as a layman who just wants his phone to work again, half of the time I don't understand what I'm doing or whether or not I'm doing it right. In other words, I realise that I've probably messed up my phone, but what can I do? I can't take it to a technician because I don't have the money for that, I can't buy a new phone for the same reason and I can't phone up and ask for a replacement because the warranty expired ages ago and I don't have the original documents here.
I've installed the Team Win Recovery Project on my phone and I have Odin installed on my PC as well.
TLDR; yes, I know I'm an idiot and I don't appreciate you telling me. I'd like to reset my phone to how it was before - the normal firmware, the normal kernel and all that, but I'd still like to have root access and keep the TWRP recovery mode too.

You'll probably need more information, so if you do just let me know and, if possible, where I can find it.
I have some good news. I managed to flash the firmware again and now I can access the phone again. However, the WiFi problem persists. I've tried looking on the internet for a solution, but I can't find one. I've tried flashing the modem and all that stuff, but it still doesn't work.
Oh, and by the way, I no longer have TWRP and I don't think I have root access anymore either (I had to do a data partition wipe as well).
I'd really appreciate a reply from someone. I've tried everything, but to no avail.

[Completed] Wacom Cintiq Companion Hybrid ( DTH-A1300L ) android needs custom rom or stock bad

I have a Wacom Cintiq Companion Hybrid ( DTH-A1300L ) android version needs help in so many ways. I bought it because I really need one for one of my jobs, yet can't really afford the crazy overpriced insanity that is a new Wacom so the reason it was so cheap was "can't connect to the Play Store. I know, hella foolish, I thought I could fix it by rooting it, but this thing is like level 10 as there is so little info as no one wanted to touch them it seems. I did find one guy on this forum that at one point rooted I am fair to average at rooting and the understanding of all that surrounds it. I have happily and successfully rooted my phones and tablet but I am no pro and fairly good at having gaping invisible holes in my info or logic when it comes to things like this.
Most frustrating is this thing is stuck on android 4 . 1 . 1 for no good reason I can imagine. It has dev tools installed after factory data reset but no google apps. (It arrived factory data reset)
I tried the relevant framework and store and the delete the cache trick to no avail. It can not update and can not even get to the Play Store.
Sooo the bad news is; no Google apps. No updates offered and stuck on some weird what looks like not stock version of 4 .1 .1 Jellybean.
When I plug it into my PC via USB it does not even show up in device manager.
The good news is I rooted it. Checked with root checker (unfortunately for now its Kingroot)
1. I have no idea how to make a back up from here. (no USB connection to PC issue)
or
2. what rom will work as my device is not listed on any of them. It would be great to find the stock rom as I am afraid this things cool and weird cintiq mode, pen function like abilities may be disabled or rendered useless with just any android rom.
Is there anyway to somehow find the stock OS on my device through boot loader? A place to find my stock or like rom. A clever work around?
Thanks in advance. for any who take up the challenge and offer any help or thoughts.
Cheers

Excuse my noobness. Flashify looks good, I installed it, but don't I need some image from somewhere either the stock OS or a new one for it to work? Not sure how to get Gapps from there.
It did I think, find something, a "restore kernel" and "stock recovery" I am unsure did it find my stock kernel and recovery and or ROM and I should boot from that? ( again apologies a-lot of new info and its getting a bit swirly) In otherwords since my device is not listed any where and at this point any working Android version will do, I am wrong to try and reboot from this? These devices are supposed to come stock on 4.2.2, so I am hoping perhaps incorrectly it will go back to that? That would be ideal at this point.
So I can work again whatever works.
Also I a bit concerned about the "date" I posted from on one of these. I think I posted from the Wacom. Perhaps the problem in deeper than I thought as that is Linux time 0?
I think it self corrected but originally it said I posted on Jan 1 1970...
As for custom ROM, I probably wont be able to make my own custom ROM, even though I would love to take to the time to learn, for now I have too many art and work related deadlines.
I was hoping for one that already existed that would work with my device.
Perhaps I misunderstood something about how all this works? Also I do not have Unbuntu. I should as I support an open internet, but WINE really does not run the Adobe products I need for work so
I am stuck with Windows.

If you just want to be able to install apps from the playstore then this is a simple alternative
https://www.xda-developers.com/unshackle-your-device-from-the-google-play-store-with-apkupdater/
If your phone is rooted then flashify can flash zips like gapps without the need for a custom recovery. If you are serious about trying to make your own rom/recovery then use a virtualbox in windows. http://www.osboxes.org/ has plenty of prebuilt virtual linux machines that will run on windows

I appreciate all your help. I got the "google of every kind from Gapps on has stopped" is over, which was intense as it popped up every few seconds, I somehow got that to quit by reloading the proper one from the APK Pure app which was an odd work around but nothing else was working. Still have this unsettling bare bones screen and none of the stock apps as well as it being stuck in 4.1.1. This device was made for 4.2. and I assume it was on here at one point.
I wonder if that alone could cause hardware issues. I thought about taking out the battery, until I realized that thing is inaccessible as a thing can be without wrecking the industrial glues and taking the entire thing apart which sounds
like an accident waiting to happen and possible making things worse. I imagine that is last case scenario.
Like I said I would love to make my stock reload, at this point that would be great as this thing seems unstable and no trick makes the play store work or allow me to sign into the device with my google email.
I think you are saying to make my own recovery/ROM of my own device I need to do the virtual box thing. Correct? Or is that for writing your own custom ROM? I can try that; make my own recovery that is, as it is not on CWM or TWRPs supported devices list so I have no choice and all in all would prefer the thing to load as if it was fresh out of the box not this 4.1. One serious hiccup I have found trying to use my PC is my device is not recognized as a storage device or otherwise. Not sure if this is due to the weird settings of Cintiq mode or simply because the thing is in a very weird state of 4.1.1. So that may make making changes via computer impossible. I am not the type to give up. Thanks again Saw
Here also is a sum up I added to a the just basic question of Can you find the Stock from a recovery device. Basically is there any way to return a device to stock with no ROMs available to do so, as in extract if from the device itself.
Additional backstory if helpful.
"I have a Wacom Cintiq Hybrid running Android 4.1 that is ( now ) rooted..
This is a very bad thing. The Real Stock ROM has palm rejection and all the drivers to make it work as a tool. So stock is the ideal but it is clearly not stock as my device supposedly came in the
box running 4.2 and with software and drivers to make it work properly with the pen. This has nothing. No software and the smallest amount of apps possible. Worse this is no custom ROM its on ( I think) as it would be the worst one ever and it was not rooted on arrival. I have no idea what happened before I got it. I may have made the mistake of rooting it really as I found out to my dismay there is no ROM support. So back to square one. I bought it ( very cheap for one of these ) "stuck and unable to go to the play store" and I did not realize until I got it, on a version of Android it was not meant for. Wacom is totally and woefully unhelpful in every way. They seem to want to quietly put this device behind them at the expense literally of their customers."

[Completed] Can Clockwork or another recovery program find and backup your truly stock ROM?

My question current is really about better understanding something in this whole Root and Linux learning adventure I think I am totally confused about.
Basically if no custom ROM exist or your device is not listed on the supported list of devices in any recovery program....
OR as in my case you want desperately to get the thing back running on it's true stock what do you do?
Your rooted, but stuck.
So my main question is:
What is the best way to bring a device back to stock if there is no stock ROMs available and factory reset will not work?
On any device in this situation. Mostly I am hoping to have it explained in a way I can really finalize this confusing hole in my logic.
Like can a recovery program find it if it is still on the device somewhere and if not, why not?
Thanks in advance.

I have discussed this problem in another thread if more details on all this specific to this device are of interest.

Hello & welcome to xda-assist,
If you rooted the device you changed the system /kernel in the process, if root is all you done you should be able to unroot by using the unroot option in your root management application, if you did further changes like deleting system apps and so on it gets more complex, the best and easiest way to get back to the original state would be a copy of the latest firmware.. If it doesn't exist you're somewhat out of luck, please refer to this link for further help & information..

Thanks for the reply. So no way to get the extract the original firmware? I don't wish to un-root. The device was set to a very sad state of affairs when I got it, unrooted, with something very unlike the stock firmware and factory date reset not helping at all. Persistently locked into a lower version of Android than it was not meant for and not running the drivers or software it would seem I need to make it function properly that came with the device.
Basically it lead to my curiosity of how one goes about extracting or mining the data that is stored somewhere on the device if all I did was root. Which is all I did.
It should still be there. Basically how do I get to it?
The link takes me back to the forums for help, however I found no help there after much searching before I asked here but thanks

The intended of xda-assist is to direct you to the most suitable board of xda, we do not solve issues for you or do technical support, please be patient, it often takes time for exotic devices / questions to be seen by someone who can give hints and answers..
Edit: but it's not that the original firmware is stored somewhere on the device by default where you can grab it and reinstall it..

Totally cool. It's a tough question.
The OG firmware thing is the toughest part to understand. Just wanted to make sure I was clear in my explanation and question.
