Help. Black Screen No Boot Fire 7 9th Gen - Fire HD 6 and 7 Q&A, Help & Troubleshooting

I followed a guide to remove bloatware from my fire 7 9th gen. The tutorial suggested a loop script for all packages with "amazon" or "kindle". I realized I had disabled packages I still wanted/needed and enabled a few of the settings packages that were missing (com.amazon.firepowersettings, com.amazon.device.settings, com.amazon.settings). I probably should have seen that as a red flag that something was off...
I followed a link on youtube by the name of "Rooting and Cleaning Amazon Kindle Fire Tablet 2019" including adding the apks (lawnchair, fdroid, etc). I also added google play and vanced.
Now I cannot get the device to boot in any capacity. Just a black screen. When connected to my PC it is recognized as Mediatek usb port (com5). I cannot get any further to recovery.
Any advice for where to go from here?
Here are the list of disabled packages if that helps:

Troubleshooting Google Play in Remix OS(v.2.0.402); Asus EeePC 1000H + Arch lnx

Hi there,
I'm nearly certain that there is some interesting glitch that I should hunt for to get Google Play working. Has anyone any experience how to troubleshoot / investigate and look for "why google play doesn't sign in"?.
The reason i'm so certain is that I've tried all the major ways of getting it to run and none of them worked and there are no more ways on the internet to try. So the only option is to analyse it in deeper. If there's quite a good knowledge around I'd be happy to do a few tests.
Firstly, i've installed remix os from Arch linux. And the installation at the end ended up being so awesome easy, that now I can reinstall Remix OS in like 2 minutes (good for testing).
Environment: Asus EeePC 1000h;
Currently installed 'N' boot OS'es:
* windows 98
* windows 7
* arch linux
* remix os
The installation of Remix OS from Arch Linux:
* created ~50GB hard drive partition as extended partition
* made the partition ext4 type and mounted it
* extracted [initrd.img, system.sfs, ramdisk.img, kernel] to new partition
* edited /etc/grub.d/40_custom and inserted new lines:
Code:
if [ "${grub_platform}" == "pc" ]; then
menuentry "Remix OS 2.0 Resident"{
insmod ext2
insmod part_gpt
set root='hd0.msdos8' #my remix os is going to be installed /dev/sda8. so this line was my "guess"
search --file --no-floppy --set=root /system.img
linux /kernel root=/dev/ram0 androidboot.hardware=remix_x86 androidboot.selinux=permissive CMDLINE #i'm using x86, if you need - change it to x86_64
initrd /initrd.img
}
fi
* grub-mkconfig -o /boot/grub/grub.cfg (make a backup of grub.cfg before executing)
* grub-install /dev/sda
* create directory "data" in the mounted partition
Whoalia. The thing I've noticed is that one I start Remix OS, it extracts all of his data into /data directory. So, when ever I want to reinstall remix, i simply boot up my Arch linux and delete the "data" folder recursively and create it over again. After booting up remix os, I've tried installing Google play in numerous ways without any success and that's what bothers me no.
Sharing my process:
1. Downloaded GMSInstaller.apk (besides trying GMSInstaller.apk, i've tried some other APK's as well)
2. Installed APK file and run it.
3. Clicked on "One-click to install Google Services" (this will automatically download google play services)
4. cleared cache of all 3: play, framework and service
5. rebooted, google play didn't work
6. cleared cache again and repeated 5-6 for 2 times
7. tried clearing google play cache only, rebooted and tried to launch google play - still couldn't sign.
8. reinstalled remix os (deleted /data and let the os reextract it self)
9. went for the local copy by executing as root:
Code:
pm disable com.jide.apppolicy
pm enable com.android.vending
pm enable com.google.android.gms
pm enable com.google.android.gsf
pm enable com.google.android.gsf.login
repeated 4-6 steps afterward, still cannot sign in (and all caches are cleared numerous times).
10. reinstalled remix os (deleted /data and let the os reextract it self)
11. used Remix Central to install google play
12. repeated 4-6 steps afterward, still cannot sign in (and all caches are cleared numerous times).
13. random gues from internet
lookung at /etc/hosts and found the default entry of local host
How should I continue investigation further on?
FINAL RESULT:
Google play worked only with Remix OS for PC Hacked Edition [ v2.0.205 included/Prerooted/Busybox/init.d/Gapps] on ASUS EEEPC 1000H!!! WOOHOOO!
Looking towards it working on latest build...
I'm having the same issues with Google Play using VirtualBox. Tried all the fixes and still no-go. I'll keep an eye here for a fix.
the latest "plain test" which didn't change anything

1- Reboot fresh and don't do anything besides what's listed below.
2- Open your apps and click/tap on "Remix Central"
3- Click/tap on "Google Services Installer" (green ". . ." icon)
4- Inside "Google Services Installer", click/tap on "Install Google Services"
5- Reboot IMMEDIATELY. Do NOT sign-in to anything.
6- Everything should work, now.

Okey, doing it "live":
1. launching clean install (2016-07-11 10:26) and made a small break
2. select your language -> English (10:34)
3. user agreement (10:34)
4. wifi setup (10:35)
5. setup completed (10:35)
6. remix central (10:36)
7. reloaded remix central twice (wasn't connected yet 10:36)
8. there's no "google services installer", so clicking on "Google Play Installer" instead (yeah, same green "..." icon, 10:37, clicking on download sign, since clicking on app doesn't work)
9. opening downloads 10:39
10. clicking on downloaded GSM_activ...apk. Google services installer launched , clicking install 10:39
11. Open after installation and clicking "install google services" 10:40
12. downloading / installing; Got a warning: "Installation completed. Please reboot your system to use google services". Pressing "ok" and keeping the rest installer window open(10:41)
13. selected to restart 10:42
14. restarting, selecting remix os to boot up, remis os logo shows up 10:43
15. Remix os booted up, The PC is online. 10:44
16. launching google play store to check it out 10:44
17 loading... and boom! "There was a problem communicating with google servers". Try again later. 10:45
18. Clicking on "next" which closed the google play 10:45
Confirming - it DOES NOT work on Asus EeePC 1000H
Extra:
19. Clearing cache of all 3 services:
Google play store - force stop; clear data;
Google play services - force stop; manage space->clear all data->ok; and force stop again (weird);
Google services frame work - force stop; clear data; ok; force stop again (weird)
20. reboot; booting up remix os (10:54)
21. launching google play store to check it out 10:55
22. loading... and boom! "There was a problem communicating with google servers". Try again later. 10:55
23. Clicking on "next" which closed the google play 10:55
24 shutting down for the next options to be tried.
Confirming - it DOES NOT work on Asus EeePC 1000H again

ok then you could try remove your account, softreboot, set your account again and try playstore...

there are no accounts added at all...
If I try to add a google account, i get the same message, that it failed to connect to google play services.
and i can't find older versions to try as well. Will try adding random, other then google account:
* adding Appstore account doesnt work
* adding Google account fails with "unable to connect to google services"
* adding quickpic account didn't help - still "unable to connect to google services" (after adding and after removing)
Tried upgrading different parts of the play store system from apkmirror.com:
1. Upgraded google play services to v. 9.2.56 (270-124593566)
2. Cleared all caches and restarted pc - play didn't work
3. upgraded google services framework to v.5.1-1743759
4. cleared all caches and restarted pc - play didn't work
5. upgraded google play store to v.6.8.22.F-all [0] 3046094
6. cleared all caches and restarted pc - play didn't work
I think this was still better, because instead of "Loading..." it said "Checking..." but still failed at the end with the same final result.
Trying to remove all the updates:
1. removed google play services updates back to v.8.3.01 (2385995-274)
2. cleared all caches and restarted pc - play didn't work, but instead of failing with "unable to connect to services" it just crashed.
3. Trying to launch play again - play didn't work as usual;
4. cleared all cache, tried launching again - didn't help
5. downgraded google services framework to v.5.1-1743759
6. cleared all caches and restarted pc - play didn't work
7. downgraded google play to v.5.10.30
8. cleared all caches and restarted pc - play didn't work, but instead of failing with "unable to connect to services" it just crashed on launch
9. Trying to launch play again - play didn't work as usual;
Trying to uninstall various applications:
* amazon - didn't help
* android bb - didn't help
* canon print service - didn't help
* google services installer - didn't help
* hp print service plugin - didn't help
* force stopped all jide services and cleared their cache - didn't help
*reset device by erasing everything - didn't help
fresh install of remix os for the next test, installing pkg's from apkmirror.com in the following order:
* google account manager v. 5.1-1743759
* google services framework v.5.1-1743759
* google play services v. 9.2.56 (270-124593566)
* google play store v.6.8.22.F-all [0] 3046094
* none opened after installed
* none appeared in settings->applications after installation
edit:
had to do previous code to enable services:
Code:
pm disable com.jide.apppolicy
pm enable com.android.vending
pm enable com.google.android.gms
pm enable com.google.android.gsf
pm enable com.google.android.gsf.login
rebooted and play failed...
* tried to clear cache after last try - failed
*downgraded current version of google play service to stock and tried dumb luck on launching google play again - failed
*cleared cache just to make sure that no magic happened here and failed on google play again.
*trying different builds of the latest google play service:
*9.2.56 (070-124593566) - fail before and after cache clearing / rebooting; however started to receive strange notification: "Google play services won't run unless you update google play services". Lol, no accounts created (empty)
* 9.2.56 (270-124593566) - was tested already in previous attempts, moving blindly with other versions...
* 9.2.56 (280-124593566) - that would be hell of the fun if worked (TV version)... but as expected after cache clear and reboot - failed, and no account created as well
* 9.2.56 (470-124593566) - parse error, while trying to launch the package (no wonder because it's for android 6+)
* 9.2.56 (480-124593566) - same as before
* 9.2.56 (876-124593566) - cleared cache, reboot - same results (failed to connect...)
* downgrading google play to default version for fun to check how it doesnt work with 9.2.56 (876-124593566) - yep, it still doesn't work
* upgrading play back up, since it's most likely google play services problem...
conclusion: * (27*) builds should be tested at any version in future tests.
I'm having the same problem on my Sony Vaio laptop booting from grub2 from my Ubuntu install.
tried to install couple of different versions:
* Google Play services 9.2.55, build (070-124180755) - although apk is x86, but it fails to work on pc since it's suited for android < 5, that is 070 built. Pointless test (however no other x86 of this version was found on apkmirror)
* Google Play services 9.0.83, build (9083270) - same results on failing to sign.
Starting to consider if it's worthy to test any older versions at all...
Testing another version of Remix OS for PC Hacked Edition [ v2.0.205 included/Prerooted/Busybox/init.d/Gapps]
* extracted [initrd.img, system.img, ramdisk.img, kernel] to new partition - ATTENTION, IT'S system.img not system.sfs as in latest Remis OS
* edited /etc/grub.d/40_custom and the right lines (same as on first post, changed system.sfs to system.img)
* grub-mkconfig -o /boot/grub/grub.cfg
* grub-install /dev/sda
* create directory "data" in the mounted partition
*after launch / installation it seems that google play isn't accessable by default as well... oh well ... let's try old stuff:
Code:
pm disable com.jide.apppolicy
pm enable com.android.vending
pm enable com.google.android.gms
pm enable com.google.android.gsf
pm enable com.google.android.gsf.login
* clearing cache of all 3 + stopping service and rebooting PC at the end
*AND IT WORKS!!!! (now i wish it would work with original version!)
Remix OS for PC Hacked Edition [ v2.0.205 included/Prerooted/Busybox/init.d/Gapps] with Google play works on ASUS EEEPC 1000H!!! WOOHOOO!
Now going to do some tests with google play
I gave it another reboot and it started to download and install applications . Cheers!

Installed RemixOS stucks at the flashing display but boot up in debug mode

Hi everyone:
I install RemixOS on hard drive following some directions found on XDA (http://forum.xda-developers.com/remix/remix-os/question-install-remix-dedicated-hdd-t3316527) to installs the system directly to hard drive without dual boot.
What i did was the following: After pressing TAB on Resident mode, i removed everything after "quiet". Then i put INSTALL=1 and then format to ext4 to use all the disk space.
The installer finalizes without errors, but when i restart and choose normal init at GRUB, the system stucks on flashing screen, then never enters to graphic env.
The things changes when i boot in debug mode. The system boot up completely but to console. I know how to use Linux, but this distro its very different to an standard one, so i need some directions to diagnose and solve the problem.
In debug mode, when i grep dmesg for error or warning nothing is found. All the devices are detected and aparently installed.
The only thing that got my attention when i installed Remix was the following messages:
- intel_powerclamp: Intel powerclamp does not run on family 6 model 15
- intel_rapl: driver does not support CPU family 6 model 15
But these msgs i suppose that are normal because is an old CPU that not support all the features that the driver does, right?
Anyway, these are the specs of the intallation:
- RemixOS version: B2016071501.
- CPU: Intel Dual Core E2160 1.68Ghz
- MB: Foxconn 45CMX
- GPU: Intel integrated on MB. I don't know the exact model
- HDD: 60Gb SATA
Any ideas to solve this problem?
Many thanks in advance.

Chromebook Acer C720P getting Google Play Store with Chrome OS 65+ recovery from USB.

It is possible to get Google Play Store perfectly running on Acer CB C720P,
off the USB 3.0 port using a USB 3.0 bootable stick with the recovery rom for Acer Chromebook R11 - it needs adjustments, & a version of Chromium OS above 55 like https://www.dropbox.com/s/kebu46foi6quu96/Camd64OS_R55-8777.0-Special.7z?dl=0
(use WIndows Diskimager to map it to usb stick, then expand the data partition file system to use up all the disk)
A great how-to for this method & the chromefy method is in post 163 by Hnk1,

Request : Can you put the link (one I mentioned above, post # 163 )in the first post mate ? So more people can install it on their CB and it will be easier to see. What you reckon?

misc notes Google Play Store on USB stick Acer C720P
Some notes:
Kernel versions -
Official Kernel for Acer Chromebook C720P: (no Play Store)
Linux localhost 3.8.11 #1 SMP Sat Jun 16 19:11:45 PDT 2018 x86_64 Intel(R) Celeron(R) 2955U @ 1.40GHz GenuineIntel GNU/Linux
Official Kernel for Acer Chromebook R11 (CB5-132T / C738T) after Play Store update (which is already in the recovery rom):
Linux localhost 3.18.0-16509-gfd728222c3ad-dirty #1 SMP PREEMPT Tue Mar 20 23:42:10 PDT 2018 x86_64 Intel(R) Celeron(R) 2955U @ 1.40GHz GenuineIntel GNU/Linux
Official Kernel for Asus Chromebit CS10 as per latest update: (no Play Store yet, though planned)
Linux localhost 3.14.0 #1 SMP PREEMPT Fri Jun 15 04:13:16 PDT 2018 armv7l ARMv7 Processor rev 1 (v7l) Rockchip (Device Tree) GNU/Linux
To me Google is playing to force consumers to buy newer machines, it's a capitalist move, Play Store runs perfectly on Acer C720P, & Google Chrome OS is far more stable & snappy than with Kernel 3.8 they want to keep.
It will be cool if a good firmware coder could flash the firmware of C720P making it look like an Acer CB R11 - that will allow to install the R11 recovery rom onto the C720P SSD - so not having to go through putting it on a usb stick, though personally, it doesn't bother me.
This would be redundant if Google + Acer decide to officially support C720P - instead of being greedy.

Ok, I found the recovery rom for Acer R11 thanks to your post - it was indeed in the conf file.
After, I put this Rom on a usb stick with Windows Diskimager - Ok
Then, I enter the recovery mode on the C720P by holding the Esc and Refresh keys then pressing the power button, and I restore the image on the USB key, so the Acer R11 image - OK
After, what do I do ? Restart the C720P ? Where should I use your script lines ?
Thanks !

this is what you need imaging to a usb stick.
then boot to the chromebook & apply the script from a shell, with the usb having chromium R55.
Here are instructions on how to do
step one - install chromium OS to the usb stick -

step two - apply the script with assumed /dev/sdb being your usb device (with chromium OS in it, which you modify using the R11 Chrome OS image from Acer/Google.
Will this work on a standard C720 (not a touchscreen)

Test it, & report
The odd bit:
Image recovery for C740 does not work, even though C720 & C740 are very similar.
Also using latest chromium OS 67 (arnoldthebat) will not work.
What I got working is Chrome OS R11 recovery with the arnoldthebat chromium OS rom I linked to above, others might work, but I posted what was successful, so I provided the links to them on my dropbox.

! @arnoldthebat latest special build Camd64OS_R67-10575.B-Special doesn't boot on Acer W700 hybrid tablet, Apple Macbook Air 2011, and Acer CB C720P (+only efi no mbr) -
your old build Camd64OS_R55-8777.0-Special works on all (efi+mbr) - I use it for this: https://forum.xda-developers.com/ha...er-c720p-getting-google-t3805304#post76864776
Thanks for the dropbox link
Ok, if I have understood everything :
- I install chromium OS on the USB key - the file is the one on Dropbox Camd64OS_R55-8777.0-Special.7z
- I copy the recovery image of the Acer R11 - link provided in the conf file - so chromeos_10323.62.0_cyan_recovery_stable-channel_mp-v3.bin
- I boot the chromebook, and plug the USB Key
- I launch a shell session (no need to be in developpper mode ?)
- I execute your script lines but should not the second line be "image_file=chromeos_10323.62.0_cyan_recovery_stable-channel_mp-v3.bin" instead of "image_file=chromeos_5841.98.0_link_recovery_stable-channel_mp-v4.bin" , so the name of the downloaded recovery image ?
Thank you for your answers
Of course -
image_file=chromeos_10323.62.0_cyan_recovery_stable-channel_mp-v3.bin

And no developpper mode needed to execute your script lines ? Thanks
And I have to boot on the usb stick with chromium ? With CTRL+U starting in developper mode ?
Wow I can't believe this! Can't wait to try on mine. I always thought it would be able to get android play store/apps on it! Waiting to see how it all works out and will try to install soon. Thanks so much to the OP for this, so stoked to see someone has managed to do this!

How'd you get on installing this? Did you get it up and running?
I am trying to find how it works for the moment - I think I know almost all the steps to be done

Please let me know if/when successful. I believe I understand it in the main, but waiting to hear re your question whether we need the Chromebook in dev mode. Mine currently is as have Linux xfce on it as well as the stock dev chrome OS image. I assume though that as this installs on the USB as opposed to the internal SSD, that chances of breaking the Chromebook as pretty remote, as you can pull the USB and go back to the internal SSD...I await your attempt!
I think that you have to boot on the USB key containing Chromium OS and the image file you want to deploy, and then execute the command lines in a shell in order to install the image on the Chromebook. After, you should be able to remove the USB key and to boot on the SSD with the new deployed image (one of Acer R11)
You need to be in developer mode to boot from usb.

Google Backup not working on Chinese SHT-AL09 8.0.0.185 (C00)

I have been trying to get Google Drive backups to work for the last couple of days on an unrooted, Chinese stock rom MediaPad 8,4" LTE with 128GB internal storage. My Google account was successfully added as backup account, however, on the active backups list, all entries are stuck at "waiting to backup". I am currently outside of China, which should pretty much prevent any VPN or networking issues. Since the China stock rom came without the Google Play Store, I added the Google Store via Huawei's own AppStore. Downloading apps from the Google store works without any problems. So I am guessing the Google services are all up and running - at least I am seeing these:
Google Service Framework 8.0.0-4147944 Updated 10 Sept.
Google Play Store 10.3.12-all (0) (PR) 108814133 Updated 16 Sept.
Google Play Service 13.2.80 (04048-211705629) Updated 16 Sept.
Earlier today I tried to manually kickstart the backup via ADB, which unfortunately enough failed:
Code:
./adb shell
bmgr run
bmgr backupnow --all
resulted in:
Code:
Running incremental backup for all packages.
Package @[email protected] with result: Transport error
Backup finished with result: Transport error
while
Code:
bmgr list transports
android/com.android.internal.backup.LocalTransport
com.google.android.gms/.backup.migrate.service.D2dTransport
* com.google.android.gms/.backup.BackupTransportService
clearly states that the BackupTrasportService is selected as default and active.
Code:
bmgr list sets
returns a plain "No restore sets"
I am somewhat running out of ideas. Looking forward to any helpful pointers...

Installing TWRP on Android Tablet with unknown OEM manufacturer

Hi all,
Background (ignore this if you like): I have an air con unit that uses an Android Tablet on my wall, it has recently started crashing with the error "gapps has stopped responding". I called the company and they basically told me I need to pay $500+ for a new tablet. I thought this is outrageous, when old air cons didn't use to use an android tablet as their control hub, they would last the life of the home!! So I'm determined to try updating gapps and fixing this tablet myself, rather than give them money.
Actual question: I'm not linux savvy at all and so I would love if someone can help me determine a way to install TWRP on this device. As I believe that is the first step in order for me to start tinkering. I'll be able to create a proper full backup to avoid bricking this thing.
details of the tablet: It has a USB port and I can connect to it fine via ADB from my PC (Windows 11), I can do shell commands etc. I tried running some queries to see which manufacturer makes this unit so i could install TWRP however everything simply appears as the company name. Example:
[ro.build.version.release]: [4.4.2]
[ro.board.platform]: []
[ro.build.version.sdk]: [19]
[ro.fota.platform]: [MTK_KK]
[ro.hardware]: [mt8127]
[ro.mediatek.platform]: [MT8127]
[ro.mediatek.version.sdk]: [2]
[ro.mtk.hardware]: [mt8127]
[ro.product.brand]: [COMPANY NAME]
[ro.product.manufacturer]: [COMPANY NAME]
[ro.product.model]: [COMPANY NAME]
[ro.product.name]: [em_t8270_nand]
Thank you.
Maybe you just don't need Google Apps and can disable it in Apps settings ;-)
The problem is that twrp needs to be made, or maybe you can try hovatek auto twrp recovery porter for mtk?
