Uncertified - Google Play certification status - ugh

Has anyone experienced an "uncertified" status in google play?

I installed the latest stock img, then installed TWRP and this rom + SuperSU and recommended Gapps. Google Play status is uncertified, and at this time I can't actually install any apps from google play.

This certainly isn't a show stopper for me, but it kinda puts a dampener on things.

I've recently revived my TF300T and am about to start a serious round of experiments. This is only round 1. Hoping someone has an answer, or a theory...

I have never see a rooted Custom rom with SuperSU Safetynet compliant.
[Transformer TF300T Android Development] TheArkive:
Please pardon my ignorance. That makes sense. I've run root on my Nexus 6 and Google Pixel without any fancy cloaking of supersu. No issues. This is the first I've seen of it. So this is related to safetynet?
[Transformer TF300T Android Development] TheArkive:
I always thought safetynet was related to Android pay, not to the Play Store and it's payment system.

I have been running v7 for a few days now. For me it seems to be a bit more sluggish than the Marshmellow v.29 build. That ROM was running super smooth for me.

I did a full wipe and format as well. Anyone else noticing this?
[Transformer TF300T Android Development] reisa:
I love the ROM, and in the hopes of making it even better, here are a couple of things I've noticed: after downloading Google Calendar, it crashes after opening. When I try to add a widget for Google Calendar, it presents the message that my calendar can not be accessed. AOSP calendar and widget work fine and connect to my account. I tried making GC a system app, but it didn't help. Other Google apps from the Play Store seem to work fine, however, Dropbox can't upload or download from the app. Accessing through a web browser works. When I installed, I did a full wipe, plus reformatted to f2fs.
[Transformer TF300T Android Development] reisa:
User note: if you're trying to use the SD card as internal memory, you'll definitely need to reboot after it's formatted. Mine started reading as corrupt during the first attempt (which it hadn't been when I was using it as a "transfer" unit). Reformatted it through Windows - which read it as a fraction of the 64gb size - then went through the process on the TF300t, and all was well. After that, it didn't immediately recognize the space until a reboot. The app told me it would take about 30 mins to transfer apps and pictures to the space now recognized as internal memory, but it took more than an hour.

Hi, great work with the ROM. Am I the only one who cannot get SuperSU to work? It seems like it doesn't get flashed...
[Transformer TF300T Android Development] chrisautrey:
I had no issues following a full format and install. I have not seen anything in the thread from others either with this issue. I would re-download SuperSU and reinstall.

Battery drain

Went from MM#27 to Nougatella #7via full format, convert to f2fs and flashing ROM, SU gapps. All went well and it works just fine. Problem this far is battery drain. On MM I lost about 2% charge over night (with wifi off) Now I lose 15% per hour (docked) and 10% per hour when not docked. Wifi off and apps hiberniated (vith Greenify) No new apps installed since MM.
[Transformer TF300T Android Development] reisa:
Update from something I've read on Android Police that might address the Calendar issue: "Unlike Google's other apps, it provides a special ability to change its icon based on the current date. This feature is currently limited to the leaked Pixel Launcher, but other launchers could easily copy this feature. One interesting note is that the Calendar app doesn't actually include a standard round icon like all of the other apps mentioned above. Instead, it provides a circular base and the 31 digits necessary to generate a round icon. Perhaps more interesting than that is the same set of icons intended to produce a "regular" icon, which matches the icon it has had for many years now. In other words, Google may not care about offering a static round icon, but obviously wants the Calendar to be dynamic in both round or regular mode. Make what you will out of those priorities. For those that may be wondering, this is also a very unique pairing between the Pixel Launcher and the Calendar app. The Pixel Launcher uses a class named DynamicIconProvider to specifically access Google's Calendar app and request the necessary resources to put together the final image. In other words, third-party calendar apps, or any app that might want to regularly change its icon, won't be able to replicate this behavior. Keep in mind that the Pixel Launcher still hasn't been officially launched, so it's too early to assume this capability won't be available to apps at launch or sometime in the near future."

---------- Post added at 11:44 AM ---------- Previous post was at 11:40 AM ----------

what is the benefit with f2fs
[Transformer TF300T Android Development] MiniBlu:
F2fs is a file system optimized for fast IO. It improves io read and write speeds as it doesn't use journaling like ext4. A big improvement for devices like this with very slow emmc storage.

I took the plunge last night - and so far, so good except for Kodi and Plex.

Neither one will play any video in any format.

I notice in the first post it says something about codecs and therefore not all videos will play... did I just fall into that?

MX player plays fine - but then, it has its own codec, so.

Thank you [MENTION=3951330]timduru[/MENTION] for this great ROM. It sure does brink life back to this tablet.

For anyone trying to install this ROM, and having issues, read and re-read the first post and follow install instructions to the "t".

Do not skip ANY ONE step.

I found out, only the Kang_TWRP to work, offiicial TWRP 3.0.2-0 did not work for me, always had issues; the main problem I had was error 963 in the Play Store. And full format of /data to f2fs.

Coming from CM11/12.1, this ROM is much, much faster and smoother.

I have been fighting issues with the Micro SD Card (Samsung EVO 32GB), but I think is the actual slot inside the tablet that is going bad (random removal, or not able to recognize the card issues). Seems only a full format with SDFormatter (v4.0 from sdcard.org, Window$ only, eegh,...) resolves that issue.

Too bad that Kodi doesn't play any videos, but, oh well.

Once again: great job!!!
[Transformer TF300T Android Development] gapecans:
This should be worked out with future updates.
[Transformer TF300T Android Development] penfold99:

Hi

I installed exactly instructions says.

But tab is continiously restarting (4-5) times and then boot up and works good.

Then i want to restart and all start again.

Have any sugggestion how to resolve this?
[Transformer TF300T Android Development] rprussell:
Yeah! Turning it off did a reasonable job!

Still not working with the really dense high-def stuff, though it does give me options. Thanks!
[Transformer TF300T Android Development] Mickk0:
Thanks for the ROM. I don't found the night mode in the system ui tuner. It doesn't exist for tf300 ? Thx for the help
[Transformer TF300T Android Development] TheArkive:
Big thanks man! That clears things up. Looks like i have to mess around more with other Gapps and/or ROMs. My current config is the same as what is recommended in the OP. I'll post my findings if i can nail anything down and replicate it.

Does anyone else have Google Play certification issues with this ROM or OpenGapps?

Hi All,

Having issues, at the stage where I flash the ROM, it just reboots right back into TWRP.

Have been able to follow all other steps up to this point just fine but I cannot get it to install the KatKiss zip.
[Transformer TF300T Android Development] pe1dnn:
The most foolproof way to recover is to return to the last stock ASUS ROM first and make sure everything works okay and then retry to install this ROM. Installing the ASUS ROM first will ensure your tablet will be in a known stable and correct state before you proceed. Your tablet currently has issues, this is by far the quickest way to get rid of those issues without having to analyze what the actual issue is.
[Transformer TF300T Android Development] elliottmarter:
Thanks for replying,

I have already done that, got an error on boot about "failed encryption" with a button labeled "reset tablet" which I did and then it booted back in to the stock ASUS room without issue.

I then:

Reflashed KANG TWRP

Did an advanced wipe of Dalvik, System, Cache, Data & Internal Storage

Changed the Data file system to F2FS

I attempted to install the zip again and it failed again, after this I made my OP above.

just to be clear

I began following this guide to install KitKass ROM

https://xdaforums.com/transformer-tf300t/general/guide-asus-transformer-pad-tf300t-stock-t3554744

I have a feeling it may have something to do with the SD card, its a perfectly working SD card (32GB new from amazon the other week), I've read the I should prep and & format it in the device I will be using it in, but when I insert it in to this the tablet (when it is running the ASUS ROM) it came up that it has detected the SD and then the "mount external storage" button made a notification flash up for a second and then go away again and it did not mount it.

After this I decided to use a spare phone (Moto G 2nd gen) to prep and format the SD card with the option for "moving data between devices" I was then able to see files on the SD card in the stock ASUS rom

Could it be something to do with updating the bootloader? When I reflashed the ASUS stock rom I think it may have downgraded the bootloader, I got it from the ASUS website though?

EDIT: OK I am going to reflash the stock ROM the one I got was through googling and I think it took me to the UK site or something, I am about the flash the stock rom Version WW_V10.6.1.27.5 from here

https://www.asus.com/de/supportonly/ASUS Transformer Pad TF300T/HelpDesk_Download/

I know the one I was using must be old because I have four icons in fastboot, someone on another page mentioned this.

2ND EDIT: So I flashed the latest stock firmware WW_V10.6.1.27.5, reflashed KANG TWRP, did a full wipe, changed data to f2fs but installing the ZIP still fails, no matter what I do it just immediatley comes back up with the TWRP splash screen...

any ideas??

3RD EDIT: I have attached the recovery.log to this post, however I cant see it appending anything to the log after I try to flash the zip

Link to pastebin logs:

https://pastebin.com/GripAp4S

4TH EDIT: from post #230 in this thread:

I have done exactly this :( I was using it as extended memory in another phone! Will try and search out another SD card to use...

I can't promise an end to these edits!

EDIT 5: GREAT SUCCESS found another SD and it is currently flashing the zip, for anyone else banging you head against the wall

DON'T USE AN SD CARD THAT HAS BEEN PREVIOUSLY USED AS "EXTENDED STORAGE" IN ANOTHER DEVICE
[Transformer TF300T Android Development] pe1dnn:
Or use proper tools...

I guess the reason it gives problems is because using it as extended storage most likely created partitions on the SD card. When using a Linux based OS (Ubuntu, Mint etc) you can easy revert this. Wipe it with zeros and it will be a blanc device, ready to be formatted as it was formatted for the very first time.

On Windows it is not so easy, in my experience Windows is not very willing to work with raw devices and tools like gparted are not geared towards Windows. But you also do not need a Linux PC, there are live boot images that can be used without installation. But of course you have to know the tools and how to work with devices.

In general anything written to an SD card can be overwritten again reverting the change, it is not permanently changed.

I would like to replace as many kk apps as possible with gaps

Thanks
[Transformer TF300T Android Development] mcfouch:
I use to install gapps based on stock OpengGapps package with a gapps-config file to remove all apps I does not need an pick up only Google apps I need.

See package comparison and advanced options on OpenGapps wiki.
[Transformer TF300T Android Development] Okiera29:
Gonna guess that Nano or Pico is this largest(albeit, the smallest packages) that you can flash. The partition for the ROM in the TF300 is tiny. That is why Tim provides apps already in the ROM. Also, Chrome will not work on the tablet either. Smarter people than I can tell you why. I just go to the play store and install the Gapps that are not installed by the ROM. Usually, Google play games is the only Gapp I add, but I only have a 32gb tablet.

Chrome is working for me without problems.

If you cannot get into the bootloader by holding the Volume Up button and the Power button together, your device is bricked for good - very sorry :(.

Most likely, the motherboard or some other component is fried. Buy one with a cracked digitizer on Ebay cheap and swap parts around. It is not hard to open the tablet and fix stuff. I have replaced the motherboard and the display on mine with great success

Sorry, Chrome does work, but has issues rendering WebGL files. At least that is what I think they are called. If you check back a few pages you can see the discussion about it. That is why I suggested not using it

So I installed this rom on my TF300T and it seems to install just fine, but i can't install anything from the Play Store. I always get a 973 or 907 download error. I've tried looking this up on the internet and there were some suggestions to clear the cache of the play store and so on... none of these seem to help. Any suggestions?
[Transformer TF300T Android Development] desireleß:
did you format /data before flashing the ROM? (...format is not wipe)
[Transformer TF300T Android Development] el_angelo:
yep. formatting didn't change a thing.

This might be unrelated, but when i tried to flash the mini instead of the nano gapps package (just one of the things i tried to mitigate the problem) i got an error stating that my 'system drive' is full. This surprises me a bit as i have 16GB and in android it shows that i still have about 13GB free?
[Transformer TF300T Android Development] pe1dnn:
The flash memory is divided into partitions. The system partition is rather small, so when you flash a too big package that partition gets full. This is regardless of the amount of free space you have on the data partition, that is an other partition. A bit like drive C: getting full when you see plenty of space on drive D:. The space on D: will not make C: any bigger.
[Transformer TF300T Android Development] ebonit:
I have no idea whether you could solve your problem or not. All you reported points on something that has been wrong during the installation process. Thus was the question from [MENTION=4594874]desireleß[/MENTION] about format /Data right. Please note, format /Data through Kang TWRP may take up to one hour and prepares your system for a clean installation.

If you still have the reported issues, please reinstall Rom, OpenGapps ARM 7.1 Pico, SuperSU stable downloaded from post #1. Before you start do "Format /Data" through Kang TWRP. Wait for the confirmation that format /Data has been done successfully. After that change file system to F2FS for Data only (no system, no cache!) Then start the installation in one run. Wipe Dalvik and reboot system. Please follow the install instruction in post #1 carefully. Finally all will be fine. Enjoy the amazing rom!
[Transformer TF300T Android Development] Theziggy:
You can use the Mini Tool Partition Wizard Free on a PC to fix the SD card too (I'm sure other utilities are available - but this is Free! )

Any comment about the BlueBorne Vulnerability?

Hi there. Any comment about the BlueBorne Vulnerability?
[Transformer TF300T Android Development] desireleß:
how can you use swap on the ext. SD? ?
[Transformer TF300T Android Development] ebonit:
Yes, here we go!

It is well known in general that Android 7 is BlueBorne vulnarable. So the TF300T as well as you may see on the BluBorne Scanner by Armis available at the Play Store.

But is this a danger like an influenza outbreak? I don't think so.

Most of the tablet user activate Bluetooth in case of need only. Me too! On the other hand to be successfully a potential attacker must be in a perimeter of 5 to 10 meters to the device. So you may deactivate Bluetooth on your device in a crowd as a precaution.
[Transformer TF300T Android Development] t3chwizard:
Just like you can use swap on the internal partitions. It is just another partition.
[Transformer TF300T Android Development] pe1dnn:
I think this is a gut feeling, or can you back this up by data? On my TF300T Bluetooth is always on because I mainly use it with a Bluetooth headphone. I think there are many more users like me but which percentage, I have no clue.

Usually Tim is very fast with updates, but maybe he has his hands full with Android Oreo so my preferred "fix" would be Android 8.0. It took quite a while before people started asking about BlueBorne here so I guess the others feel like that too :fingers-crossed:. Do not disturb egg laying in progress... :laugh:
[Transformer TF300T Android Development] el_angelo:
I did format (I do know the difference between formatting and cleaning)

I only have cwm installed though, and format certainly doesn't take an hour.

What exactly do you mean with 'the installation in one run' you mean i should do a multi-zip install or can I install the zips one after the other (without a reboot in between)
[Transformer TF300T Android Development] MiniBlu:
Well there's your problem. You can't use cwm

Follow install instructions and you won't have a problem. Use kang-twrp and for format use the big "format data" button. It the only way to do it properly.
[Transformer TF300T Android Development] pe1dnn:
You are of course free to use your own way of installing but I think you will not get much help here if you do. Formatting ext4 should be fast normally if you only write the filesystem structure, but I think TWRP also actually resets the storage which of course takes long. Next thing after that is change to F2FS, no idea if cwm is capable of that.

Installation in one go means install the zips back to back without a reboot in between. Also the ROM first and only then the others, the order of the others do not mind but the ROM obviously does. If you reboot in-between then start all over. Booting a half finished installation will make changes that can only be reverted by clearing everything again. Also be sure to wipe caches.

I can not get my head around why on earth you want to use different tools to install. If you read through all the previous posts you will see a awful lot of problems from people using all kinds of alternative installation methods, despite the one on the front page having nearly guaranteed results (if that doesn't work, go back to the stock ROM and then try again). Do you not like guaranteed results but like to gamble and get a head ache to find out what's wrong? Why should you? What is so attractive about using other tools than the ones that work. It is worth to have unstable results with no support?

I know, it is your choice, I just fail to understand why.
[Transformer TF300T Android Development] walttheboss:
Low level format simply advises anything looking that the partition is a certain type. Kang TWRP does a deeper format that rewrites everything in the partition. No moldy leftovers. Many of us followers of [MENTION=3951330]timduru[/MENTION] have done it many times. It takes a very long time. But it works.
[Transformer TF300T Android Development] t3chwizard:
My Bluetooth is always off.
[Transformer TF300T Android Development] el_angelo:
OK thnx for your rant. I simply missed the explicit instruction that I was supposed to use KANG. I had cwm on mine because i had to replace the glass and i simply couldn't do a thing with TWRP. As CWM allows formatting i thought that would be the same... obviously there is some difference as now it is working...

So thnx for clearly pointing out my erroneous ways.... ;)
[Transformer TF300T Android Development] pe1dnn:
I'm sorry you took the heat, you are by far not the first one with these problems so thats why I and others react a bit grumpy when the next guy comes along with the same kind of problem. So my apologies.

Note that just any TWRP version will not cut it either, there have been many versions with various problems. The one specifically mentioned is known to work fine so that's why it is safest to stick to that.

One other obvious failure frequently made error is not having the latest bootloader. If you ever had the latest official ASUS ROM then the bootloader is correct, but if you only had an older version then the bootloader is outdated and will not be able to boot KatKiss Nougatella (it will boot-loop). So then you first have to install the latest stock ROM to get the bootloader updated and then proceed to install this ROM.

Good luck, if it works your tablet will feel like a complete new one so well worth to try.
