Erisin ES7835US - Android Q&A, Help & Troubleshooting

Hey devs I purchased a car tab from China and I have borderline bricked it. I bought the Erisin ES7835US (ES7835A I believe) which has android 4.04 installed. I hit the reset button and I believe I've erased the additional firmware included. I am able to boot, but it asks me to calibrate and start setting up the tablet as if its my first time using it.
I then notice quickly that I cannot install any apps from Google play, it tells me I don't have enough space. Funny thing is when I go to settings/storage my internal SD card shows all green (full) even though I haven't installed any apps.
My internal SD card is recognized by my computer and I can add and take stuff off of it. Its like android is not reading any space to install apps.
It has ANDROID SYSTEM RECOVERY <3e> and I don't see cwm or twrp available for my device.
Is there anything I can do? Repartition my card? Flash a custom recovery? Please help!! I'm taking all responses and suggestions and I'm very computer savvy, I flash pacman ROM 4.3 for my note 2 daily. Please don't be afraid to reach out and help me...I WILL donate $10 via Paypal to whoever helps me with this.

You ever get this figured out? I posted links (search my screen name) to multiple Erisin ROM's, now I'm just hoping to find a Dev (preferebly in the Seattle area) who can help me install the 7835 software onto my 7035, or at least root it and help me make it somewhat faster, less buggy, etc.

Bump since you're still an active user on this forum. I've posted links on the end of this thread of the firmware you needed - http://forum.xda-developers.com/showthread.php?t=1119778

Awesome! The next time that I see my mom I will have to have one of these ready and flash her main device back to stock. If she likes it, then I'll put it on permanently.
Amazing work, can't wait to test it out.

Always there to serve massive amounts of data.
Just post an NZB file here.
Just wanted to stop and say 'Thanks Albert!' for taking the time to do the video and list out all the steps. I had a few hiccups along the way but like with anything in life, persistence paid off.
My specific issues were not realizing the actual theory of what was going on here. I had to download the google apps .zip file extra and boot back into CWM to install it. I didn't understand that part at first. I wasn't prepared to actually keep an extra sd on hand for the occasional install/backup but I had a 2gb sitting around which worked out perfectly.
Again, thanks and all is working good as of right now! I also missed the part, if it was in the video and I passed over it, about installing the Nook Recovery.apk to install CWM. I blame lack of sleep.
if you added the sideloadable app packet, in there is an app called recovery flasher. this app allows you to install CWM on the tablet itself
I need to figure this out or I'm going back to BN stock firmware. This seems like the best option before i go back stock.
I wanna say I figured it out and you helped me in the other thread. I love the one you have background says tabletroms. Only issue as of now is when you bootup i get an error. The application Nook Unroot (process com.indirect.nook.unroot) has stopped unexpectedly. Please try again.
Not sure what thats about though.

I also tried without the cable using the power + n button and no matter how long I hold them, nothing happens. If I take the SD card out, it boots as normal.
I am also running 1.4.2. I just purchased the Nook yesterday. Could that have something to do with it?
I have gone through the entire process of making the R3 card twice and I get the same result. The nook will not boot up with this SD card in it.
is this an 8gb or 16gb nook tablet? it will not work on the 8gb
Mr. Wertz,
Please allow me a few moments to sing your praises (and those for everyone else involved in the creation of your wonderful 3R SD card!!)
I have no programming skills to speak of. Originally rooting my 16gb v.1.4.1 Nook Tablet was a long and tedious process using ADB, and drivers, and my computer, and several different files...
However, I eventually got it done, installed TB-Pro, homecatcher, Go-Launcher, and aproximately 177 other apps, books, and games... I was happy and content.
THEN Evil B&N pushed 1.4.2, killed my root and basically made my tablet non-functional (at least in the ways I was using it!) Lucky thing I had a recent TB backup of all the apps, but no way to restore them...
While searching XDA for a 1.4.2 root I came across your 3R SD card post... My time and frustration were worth more to me than the very modest price you were quoting, so I took that leap of faith and purchased the 3R along with an extra blank card...
Imagine my surprise to find the envelope laying on my doorstep the next morning when I returned home from breakfast with my wife!!! Your later email explained that you just happened to be in town on vacation, and had hand delivered it to my door! It being St. Paddy's day, I felt like I'd caught me a Leprechaun!
I watched your 3R instructional video at least 3 times, and read all the 3R related posts here and on TR Forums then Monday I rooted it, and then restored it back to out of the box factory condition! Following along with your video as I went it was easy as pie and worked flawlessly 1st time without a hitch!!
Tuesday I took it back to B&N and had them repartition it to give me 8gb of the 16gb internal storage! (Ye-Haw!!)
They had to look up the process in their manuals because that store had never done it before! LOL!! It took them longer to repartition the storage than all the time I spent Monday and today using your card and customizing it just the way I wanted it.
I had never bought apps from the B&N store, only books, so this morning (again following along with your video) I Put my trusty 3R back in and installed CM7 rooted, CWM (OTA now Fully Blocked) verified v.9.9.9 and got TB-pro back up and batch recovered all 179 apps, books, games, etc... I also downloaded the Android readers for both the Nook and the Kindle so I lost nothing and have a better tablet than ever before!!!
THANK YOU SO VERY MUCH for making what looked like a probable nightmare into an easy and FUN experience!
Now if you only had a magic SD Card that would push a fully rooted ICS Kernel and Rom into my AT&T Samsung Galaxy S Captivate... LOL!
Many Regards!

R3 Card in my situation
Hi Albert
RESOLVED!! Got N 4.6 root installed! Moving on to R3 card...but, take a look at my post on N 4.6 root thread, problems with supplemental apparently download. One question...all seems to be working (root confirmed using S EXPLORER, BUT device still reads BN 1.4.2 installed. Afraid of OTA but will probably upgrade to CM7 before one hits, I hope. Is this correct?
Thanks Albert
NEVER MIND BELOW.
So, I never got around to installing CM7 as we discussed in PM. I was still running your N4.5 root when HBOgo updated their app and I lost that application. Being the moron I am at times, I did not realize this was the cause, and thought somehow I had lost my root in backing up my SD card to my computer a day prior. So, I took my trusty CWM/N4.5 root card I had saved out and attempted to go back to factory install and reroot, assuming I could get my HBOgo back and then later install CM7 on an SD card as I had wanted. Oh well, I did that and even remembered to block OTA updates in NT Hidden Settings, but alas HBOgo was not working. Finally I realized my mistake...all I should have done was taken a back up of the earlier HBOgo app and replace the nasty update! Too little too late. So, I must have made a mistake in reinnstalling the root because I now have a tablet reflecting I'm running BN 1.4.2. I still have access to both the amazon and google play stores but having trouble downloading new apps from google play. AND, every time I try to run HBOgo I have to go back into Settings and clear a cache etc. So, i've borked the whole thing!
So, I've read through the site and discovered your R3 post and thought perhaps this is my best solution! (I am less enamoured with having the SD version of CM7 now that you have created this nifty little R3 card!).
My question is, can I go directly from where I am (BN 1.4.2) with some weird half rooted ?? version of N4.5 to CM7 using your R3 card? My concern is not the 1.4.2 as your video shows this isn't a problem. It is that I was rooting using the N4.5 rather than the N4.6 which you reference in the R3 tutorial?
I think this is the best plan but am hesitant to go for it. Your thoughts would be greatly appreciated!
Thanks.
Lisa
Disregard last post
Needed to download update to NT hidden settings to get OTA block and unauthorized apparently...just in case someone else runs into this.....not sure if NT app is old on zip or if my TB reinstalled old app version but there you have it.
Loving root with BN access....may just keep instead of CM7. As always thanks Albert.

You can build a bootable CM9 and/or CM10 SDcard (but it's not a R3 card with CM9/10) using the instruction and files posted here and here.
My 16g has a corrupted partition table. I've tried every other repair/recovery method without any success. Does this recovery repartition as well?
Thanks for what you do.

[Q] What are the main differences between the three rom types?

For starters. I am a Nook noob and I am not affraid to admit it.
I have read, read, read, and then read some more about rooting, roms, CWM, CM, and so on and I did puzzle most of the pieces together, but not all.
If I got it right there basically are 3 different roms one can choose for the NT:
Stock rom (the original state)
Stock rom Rooted
Alternate roms: CM (7,8,9), MIUI or any other variation of Android firmware distribution
The usage distribution of the roms can be found in a poll here.
Stock (original) limits you in using full potential of the NT, which typically means that you can not use Google Drive, install/use any apps other then the ones Nook market provides. You can not put apps on the home screen, use any widgets and you are very limited in what you can alterate on the system.
Stock Rooted is the state in which that you are still using the original firmware, however you now have root acces. This means that you have acces to Google Drive and are able to install/use most of the apps on Google Drive on your NT. You can use various launchers to access these apps and can set a launcher as default instead of the original launcher.
The easiest way to get here is by rooting your NT through an SD card. You only need the SD card for the rooting process. The (rooted) firmware remains on the internal memory of the NT.
In this, you:
Still have acces to all the original Nook apps and features (you are still using the original Nook system)
You have the possibility to UNroot the device and turn it fully back to it's original state
What I am not sure about is:
Can you use / place apps on the home screen?
Can you use / place widgets on the home screen?
Are there any other important differences between Stock (original) and Stock Rooted?
When going for an alternate rom, you have a diversity of choices, but all are fully seperate roms, that either replaces the original firmware or complements it (dual boot). What you get in return is a fully functional, tweakable Android system, on which the version depends on the rom that you choose. You can access Google Drive, install/use most apps, place widgets, use different launchers, etc.
The easiest way to get here is by using a SD card. I can not find the specific topic that explains the procedure though. It seems that you can choose to maintain the original firmware and place the rom on the (external) SD, which leaves you with a dual boot system, or you can replace the stock rom with the custom rom.
In this, you:
Loose usage of all of the NT's orininal apps and features (when using the custom rom)
What I am not sure about is:
Where in the process you can choose to either place the custom rom on the (external) SD or install in the internal memory.
Are there any other important differences between Stock Rooted and custom rom?
My main question is: Can you confirm my findings and help me answer the questions/uncertainties?
I can imagine this thread would be of help to others who spent a lot of time reading, but are left with some basic questions. That is why I took my time writing it.
When you use the sd card method, I use a cm7 card when I boot the tablet with the card it boots up as a regular android tablet. It's does not install anything permanently to the tablet. I get full google play. Like I said no nook software at all just android tablet. I use the nook app if I want to read. It has the cool page turn animation the nook software does not go figure. Take out root sd card turn off and turn it back on with no sd card or an unpacked sd card, it boots up just like it came out of the box. All app installs music anything put on the nook with the hacked card in it goes on the card. You have no access to the nooks memory except ram which gets cleared as soon as u restart it. As long as the hacked sd card is not in it there's no way for anyone to tell you've done anything to it, cuz u haven't it all stays on the sd card. Performance is great I play 3D games like mad trigger with no lag, it's the best of both worlds & only way to go if u ask me. I don't know why anyone would do anything els. It's just to easy. Hope that helped.

Thread moved. While I appreciate the effort you've put into this post by reading up and finding out about all the different ROM's, you need to also look to make sure you post in the correct sections of the forum and this is also stated in the sticky in the General section, not to post questions in General. If your thread is a question/multiple questions and you even tick the "Is this a question box" when creating the thread then you must post it in the relevant Q&A section.

Thanks, that helps indeed. So basically you only use the CM7 rom, and neglect the stocked software. Sounds like an attractive approach. Thouh it is a bit of a shame that the 8 or 16 GB of internal storage are not usable then.
@AvRS: I did read the section about no questions in the General Forum's policy. I actually thought I posted in the Q&A but appearantly I didn't. I probably started the thread just before I read that part. Thanks for moving it to the proper section.

For the first point: Not on firmware 1.4.3, but on lower firmwares you can download an app called Nook Color App Manager (you have to side-load it as it is not in the Play store) that will allow you to do just that.
For the second point: You cannot place widgets on the Stock launcher. You have to install an alternate launcher for widgets.
Also, I think you mean Google Play, not Google Drive.

Unless you re-partition your Nook, you never have access to the full 8/16GB. You only have access to the 1GB MyNook partition. You have to re-partition (or have a B&N store do it for you) to get more space for user apps.
Ok guys, thanks for all the answers. A lot more is clear now, but definately not all. Also, yes I mean Google Play / Not Drive (doh, my bad)
As I read more and more, it becomes clear to me that all the information about rooting the Nook is soooooo spread and unorganised. It is nearly impossible to make an informed choice without having to spent hours and hours of reading the forums.
Just now for example, after a total of 2-3 hours reading the forums, it came to my attention that there is a big difference between the 8GB and 16 GB NT and that some rooting procedures can brick the NT8.
Anyway, on with the questions:
It seems that the latest version CM10, is the one that currently has most of the attention and most of the development resources go to this. Is this version now steady? Also for N8GB? Are there still big issues, like: no microphone working, sudded reboots, crashes, etc?
I read that CM9 is no longer being develloped. Is this version steady now? Also for NT 8GB? With a working microphone, no sudden crashes, reboots, etc.? Or was it abandoned while unfinished?
How about CM7? Same questions as the above.
So basically, even afters hours of reading, I still have not figured out which version would be best to use for my 8GB NT, if I want full Android functionality, but with everything working steady (also microphone) and avoid any big issues.
Hope you guys can shine some (more) light on this.

Answers:
1) Most of the dev's I believe use NT 16 GB so NT 8GB is a bit of a risk.
2) True, CM9 is no longer being focused on, Jellybean is the center of attention. No it is not considered steady/daily driver material. You might as well flash a jelly bean rom if you are going to flash a newer rom on ur NT.
3) If you want a guarantee that a ROM will run on the NT 8GB, the CM7 ROM by celticwebsolutions internal version is your best bet. It should be guaranteed to work. All those features you mentioned should be working. VOIP does not work on any of the ROM's currently
Number 3 update
Just one update on part of the question, answer to 3); Magicjack app works on it.

Thanks a lot, that really answers most of my questions. To keep you guys on edge, just two more :
With the CM7 'celticwebsolutions rom' you mention 'internal'. I assume that you mean that this rom overwrites the stock rom. Is there an alternative 100% steady CM7 rom that can be loaded aside the stock rom (on external SD)?
Does the rooted version of the stock rom support VOIP, such as skype?
"Does the rooted version of the stock rom support VOIP, such as skype?" Nope, rooted not rooted on any version will not support direct Skype or Video conferencing app that I know of on NT. This may change once OTG is implemented in future development.

for your first question, there is an SD version but it has not been confirmed to work with NT 8GB
You can however make your own internal sd card version using the internal version provided here and instructions that are listed over a succulent's blog: www.iamafanof.wordpress.com
if you aren't all too tech savvy, I would advise against making your own bootable SD, but if want to experiment and learn a thing or two, go for it!

There are instructions on how to install/create your own SD Card version of any ROM, you just have to try it out.
Skype isn't supported at all. It will install (according to the Play Store online) on my JB (AOKP) NT16, but I don't think it will run. For one thing, there's no camera or camera support.

Why not use Magicjack for voip, it free unless you want to get the dongle for less than $30. With video conferencing app like skype, you can only text but what the point of that.

[Q] Can i unroot my phone but still have a custom rom installed?

Had my phone for a few months now and at the moment its rooted and ive installed a few roms on it. At the moment ive using Omega Rom which i do like apart from a few issues. Camera always asks me to install SD card.... even though its in. Anyway, not bothered with that for now.
Got 2 options at the moment.
1 - Unroot and install stock Samsung Firmware. I want to do this as there are 2 apps that dont work with a rooted phone which id like to use. Samsung Video App and NowTV. Id like the samsung app to work as when i 1st purchased my phone i had free credit to spend on it and i purchased a few films on there which ive never got round to watching. As for NowTV and possibly SkyGo, i need my phone rooted for these to work,
2 - Stick with a rooted phone and custom firmware. Im keeping an eye out for the new JellyBam v6 which hopefully is released this weekend.
Ideally id like to have the Jellybam rom installed with my phone unrooted. Would this be possible??
SuperUser app -> remove root
jellybam v6.7.0 Samsung GT-I9300
hi guys, it's my first post so i hope i'm in the right place.. just flashed jellybam v6.7.0 onto my phone and it's amazing, so smooth and quick compared to stock android jellybean.. however, i've got a constant message in my notification bar that says "blank SD card" and it won't let me mount SD, it keeps forcing me to format but i don't want to lose all my data. i've tried the card in my computer and it's definitely not corrupted, and all the data is still there. has anyone got any ideas what the problem is or how i can fix it?
many thanks in advance,
cheers

Ok, so I'm an amateur Android root hacker and I was trying to install a DL'd Android file (volt) to swap external SD to internal phone staorage. I messed up. Now the tablet will not boot, as it gets stuck in the logo screen. I have tried ALL reset methods including recovery mode. When I try to select recovery mode, it only gives "NO" as as an option to factory reset. I have read online that I may be able to boot Android from an Micro SD card but this is where I get stumped. Can I use ANY 4.2.2 build, or is it device specific? If so, how do i find my build on a generic tablet such as mine? Here is what I can tell you about my tablet. It is a Tagital 9" A23 running 4.2.2. Here is title to the exact tablet on Amazon that may include some useful information. I can;t post the direct link because of my NEWB status.
TagitalĀ® 9" Android 4.2.2 A23 Dual Core Dual Camera Tablet PC Play Store Pre-installed (Enhanced Version of A13)
As you can see, I'm only into the device for $75, but I would not only enjoy a working tablet, but also a solution to the original issue of partioned internal storage being all out of whack (502mb for device storage and then 4.8gb available, partitioned internal storage, not being used).
I apologize in advance if this is not the correct area to post, but I am a newbie. Please help!
Yikes. Sounds like you made a brick. I'd recommend looking for support via the manufacturer web site some have stock Roms for devices. Did you see if anyone had a thread here for that device? Good luck.

Yeah, that's what I was afraid of...I just bought a duplicate tablet today, having it shipped overnight, do you think I can mount a recovery image from the new tablet and install on the first?

just wondering...
i'm kinda stumped.. but if you can get into recovery I believe you may be able to either download a compatible rom several that sound like they would work on your device(search via Google) or maybe backup the new one you just bought and push those file to it(Maybe via adb)/ make a flashable zip and reinstall via sd... speculating ovi cause I don't have that style of tab...

Z4 RK3368 Android LP5.1/MM6 Octa Core 64bit 2/16gb TV Box

Hey Guys,
I have a couple questions about this android box I purchased that's had me somewhat puzzled.
I have been an avid android user over the past many years. I am familiar with flashing tons of roms to all the phones I have had. Except my s6, it just sucks for roms. Anyways I have purchased the android box in this link (can't post links this new) I can't seem to fine a manufacturer website, I've Google a million things about the box and searched but I can't find anything. even in the instruction book there's no website or anything.
basically I'm looking to figure out how to at least update this box. there's no option in about device. also I don't like how the flash drive on the device is split into nand flash and regular storage. I would like to merge them all into one. I am also looking for custom roms that might enable me to achieve that, however nowhere I look has this box in their forums or anywhere. maybe it's a cloned box? there are other boxes that have the exact same components (or so they say) with custom firmware, however I don't want to chance it and rich bricking this device.
anyone that can offer any help or lead me in the right direction would be greatly appreciated. thank you in advance!

I just picked up one of these about a week ago and found instructions to install TWRP and update SuperSU. The box had 'root' out of the box but it was some specialized root based on an old version of SuperSU (1.93 I believe).
I have successfully installed TWRP 2.8.7.0 and updated to SuperSU 2.46.
Since this is just an android tablet essentially, does anyone know if you can flash these ROMs through TWRP?
Not to my knowledge, just use above tool. It will go alive once you are in bootloader with usb otg cable connected to win (of course with driver pack etc. installed). Titanium or else can do that, instead of trying to press reset button while powering on. Of course recovery will go back to default.

Are you running liamstears custom ROM or the 12/22 factory firmware?
The split internal storage is something I would like to do without, but I was wondering if it was changed on the 12/22 factory firmware?
12/22 firmware. Fast and stable.
Havent tried liamstears yet. Feedback if you do please.
awesome thanks! thats what I suspected when I was going through the firmwares for these devices. I just wasn't sure if the z4 rk3368 device would work on this one. I've seen a few brands with z4 and as I know with phones.. wrong brand and you're bricked lol. anyways.. I ended up buying a tronsmart vega s95 telos.. but it didn't come rooted. so I rooted it and now I'm getting play services force close and all sorts of bugs and errors.. maybe I'll just keep the z4. it seems to work better.
what link did you follow to get twrp installed?? same thing I'm guessing, punch z4 twrp in google and eventually come upon the right place.
12/22 factory firmware? mines stuck at Nov 10 I think.. it won't let me update using the rk settings app.. which is why I was fed up with it in the first place lol.
12/22 firmware. Unified 16gb App storage. More available with microsd card. Fully functional Kodi with channels, etc. 4k HEVC x265 movies. Youtube 1080p.
Easiest method to update rom is to put extracted update.img from zip file
http://chinagadgetsreviews.blogspot.ro/2016/01/download-latest-android-lollipop-511.html?m=1
on a sdcard / usb and boot. After about a minute into the Android desktop, system will ask for update prompt. Only applicable to system still with default recovery.
If you have some stability issues or with different recovery, you can backup your apps / data with Titanium etc. and then use above Factory tool restore new rom.
These roms usually come with their own recovery, but some modded ones with TWRP/full root, supersu and all. But you dont really need them.
thanks a lot man! I'm downloading right now and will test it on my box tomorrow after work!
I've tried 100 times and it just keeps saying failed to mount /mnt/external_sd (no such device)
I'm using my USB flash drive.
this is becomming a huge pain in the just to update I'm starting to think why this company can make these products and not have any support or anything for it . and that flash tool is in mandarin and I can't even figure out how to work that. I put in the update.img and press go.. but whenever I try to boot to download mode like you mentioned in one of the posts it just turns off the box.. this thing is literally a piece of junk. and so is this tronsmart vega s95.. same thing. it's extremely frustrating. whoever developed this z4 box did a really chappy job on the firmware.. and I do not recommend it to anyone..
If you had gone through the instructions pdf, it clearly shows how to change into English by pressing the World icon. Remember in bootloader mode the tv screen would be black, if you are using the tool. The big red button will turn into green to show readiness.
For automatic update you dont even have to go into recovery as seen in attached image. Easiest.
Hi Roland,
love to see that there are already XDA-members looking at the Z4 TV box. I have just ordered one and hope to get it within a few weeks. Just some dumb questions, hoping you can provide me with some information:
- I see that there are several 'versions' of the Z4: for instance Acemax, but I have ordered the Andoer. Are those just different manufacturers?
- Are there any differences in model/content (installed app's) per manufacturer?
- If my Andoer turned out to have an older firmware than the 22/12, could I still use the Acemax 22/12 firmware you refered to in your link?
- Kodi will be preinstalled, I saw. I do not know what version of Kodi that will be, but can it just be updated to the most recent version in the Google Play Store?
- I do not know what other apps are installed, but is it possible to de-install apps you do not need, or are they part of the firmware and impossible to delete
I know, part of the answers I surely will discover once I got the Z4, but I just can't wait to start experimenting, even it is only in my mind
Thanks in advance!
Jos
hi Roland
I tried that batch tool first which is the one I couldn't change languages in lol. but the other tool with the red button I changed into English. however I did not know that it would remain blank when in download mode. I will have to give it one more go tonight with it. I figured that I loaded it into bootloader and the z4 box light turned red so I thought it was off and didn't load to bootloader.
I also did the USB update and it would just fail on me every time I used it. the update prompt did come up and I pressed install. perhaps I need to check if USB debugging is on. I think it is but it wouldn't hurt to check. but I think I will have to go through the factory tool to update way for sure.
thanks for your help roland, I will write back after I give it another go tonight!
i can't find the 22/12 update ! can anybody share the link direct to firmware ?
@DriftJos
l have got an Andoer too. Most of these brands come from the same hardware factory and thus have the same specs/apps.
Yes you will use the same firmware https://mega.nz/#!JBBXgDgC!VSra8Hc6KR77Pvdw67eDpjeT_ku-TXdYgYaInSAfyvU (direct link @prisim) or several user dev roms. Unified 16gb app storage etc and the works.
You can uninstall bundled Kodi (by Titanium free etc.) by official Kodi Jarvis 16.0 beta 5 & such with pass-through support test builds @ http://forum.kodi.tv/showthread.php?tid=252852
Again you will be able to uninstall useless apps directly or through Titanium.

Always mention the firmware version you are having and which recovery? The automatic update should work if you still have the factory recovery.
Check the FactoryTool process in attached images.
I'm trying to flash the firmware that I downloaded from that China gadgets site that was mentioned on this thread. I think it's the stock 12/22 for the device. and I have stock recovery.
I extracted the update.exe file and saved it to my USB drive plugged it in and restarted. relieved the update prompt. chose install update and it rebooted into recovery and tried to apply the update but it fails. I'm not ready to give up yet with this device lol. it's just another platform I have to learn. it took me a bit with smartphones to figure it out back in the day.. perhaps it's the same thing now..
and I'm updated to 12/22.. awesome. those pictures really helped me man thanks.
now as for installing twrp and all that. you mentioned that it's not really needed? I'm assuming I can flash any rom given they are in .img format using factory tool. however the benefit of twrp would be an easier interface for creating nandroid backups and clearing cache/factory reset. perhaps I will install it. i might give leamstears rom a try. I will let you know how it is if I do.
thanks again!
so I updated to the new 12/22.. everything works fine except with Google play store.. I keep getting a can't retrieve source error with everything I try to download. I've refreshed and factory reset the firmware 5 times now and kept trying.
so I got fed up with the stock so I tried leamstears rom and it works great.. except sometimes it just becomes completely unresponsive. I'm starting to think there is something wrong with this box. even on stock firmware from the box I've been having issues with unresponsive freezing.
what do you think of the nvidia shield?

The PlayStore error you were seeing is because the 12/22 firmware comes with a *very* old version (5.2.x). The PlayStore will eventually update everything to the latest version by itself but if you don't want to wait, go over to apkmirror.com and download PlayStore 6.0.5 and install it manually. Once you do, it should also update the Play Services to 8.4.x and your should be good to go. I had this issue as well but I had seen it before and knew I needed to update.
So far the 12/22 version has been great, and having the unified internal storage is a huge plus.
If you feel so inclined, knowing that some of the custom builds of Kodi take up a large amount of space... there is this trick that was introduced in Helix:
http://kodi.wiki/view/HOW-TO:Change data location for Android
This will allow you to have only the Kodi app on internal storage (~125 MB) and any data from addons/programs etc. in another location (such as an external SD).
I often
1. Install Kodi on internal storage
2. Zip up the contents of org.xbmc.com directory
3. Copy it to external storage
4. Unzip it in /external_sd/kodi_data
5. Create the xbmc_env.properties file that references my Kodi data location.
6. Delete the contents of /sdcard/Android/data/org.xbmc.com/
Voila! You have freed up internal storage.... You can also persist a Kodi setup this way or run multiple custom installs. If you re-image your media box, you can re-install Kodi and as long as the xbmc_env.properties points to your external_sd with your Kodi data, it will start right up back into your setup... :good:
