[Q] Force Close Loop -- android.process.acore

I am not sure I have the technical skills to be posting on this site but here goes...My Kindle Fire is stuck in a loop after the swipe uplock screen. The error screen pops up "Sorry, the ics 4.0 application launcher (process android.process.acore) has stopped unexpectedly. Please try again." I click "Force Close" and screen comes right back. I checked and I can USB to device and see files, and it is fully charged. A hard reset doesn't work. Can't get to Fire settings or any other screen. Amazon Customer Support was no help. This was caused by me installing ICS launcher and not knowing the risks. Any backdoor way to reset Fire? Thanks for any help.

Use adb to uninstall the package?

You can use kindle fire utility to reset the device. Seriously, before modding, you should always have a way to access recovery mode, so, install firefirefire and twrp

Thanks
I appreciate the fast responses. Will try and let you know what happens.

I have the same problem and i'm not sure what yall are talkin about ... Can someone explain PLEASEEEE! I root my phones all the time, so I figured this couldnt be that hard.... Guess I was wrong! I had it going fine until I downloaded ICS launcher

I used the Kindle Fire Utility (KFU) v.7 to root the KF using BurritoBoot (I think) and then installed TWRP on the KF. With TWRP running I selected the Wipe option, then Factory Reset, and this fixed the problem...I had the Kindle back to where it was when shipped from Amazon. Of course the KF needs to be attached to a PC to do all of this and you need to install a new device driver ("ABD..."). The driver is included in the KFU package.

Hope this helps. Wish I had taken notes when I did this.

i just fixed mine
brother installed ICS launcher---and kept it in a Force Close loop. couldn't even install anything like twrp through the KFU. but! i was able to get it working just by----
download the KFU from above--
use the Extras option (6?)
push the ADW launcher (option 2)
even if it says successfully installed--let it keep going. when it finishes, unlock the screen--and it should ask you which launcher you want to run
select the Kindle Fire, set as default, and voila----fixed!

Thanks yall

Thx I used the newest kindle fire Utility (I did not had an recovery System) So it worked perfect for me thx

If anyone else ever gets this problem theres an easier fix that doesn't involve installing anything. You touch the top pulldown screen when you take out the USB or put it in to your PC to mount it, and with trial and error you'll manage to get the settings screen. Go to applications, and uninstall the app giving you the problem.

help please

Kindle Books/Docs not showing up.

I've browsed through the threads and seen hints of people having this problem, and I wanted to make a thread around it. The problem being that Documents and/or Books not being seen on Cloud/Device.
I bought my KF for reading purposes, full functional Tablet second. So this is rather frustrating.
Some posts have hinted that this may be rom specific. But I haven't flashed any roms. Only rooted with SU.
I did wipe and re-root with SU, and my books/docs came back for 2 days but now they're gone again.
I've seen others have this problem. Is there a fix?
- D

this only happened to me when i mistakenly turned on "Update Automatically" in Google Play/Market and it auto-updated the kindle app to the one for normal android devices. once i uninstalled this update, (and turned off auto-update), everything went back to normal.

I'm not sure about the stock ROM, but any other ROM has a kindle directory on the sdcard. Might wanna check if your books are missing from that directory.
i.e. sdcard/kindle/

I am having a similar issue.
The problem is that, even tho the Docs are showing up at the Amazon Launcher, once i click on them, nothing happens. Not even downloading them works.
What is going on here ?
[EDIT 1] The only way i can see them, is to use the "kindle" app that is on my app drawer.
With this app i can download the documents and open them, but not when i'm on the "Amazon Launcher"

That worked for to get things started, I then de-registered and registered. That brought everything back. Bottom line, I guess, don't let market update the kindle app.

How to open books in Kindle (Launcher) and Android (Go Launcher EX) environs

Hi All,
System info: KFU 0.9.6; Kindle Fire 1st gen, OS 6.3.1; Google Play -> Auto-update apps -> not checked
I successfully rooted my device and my books and docs are showing up in my Kindle (using Launcher) but they do not open. When I try to open them, all I get is the the orange color kindle logo. The device just hangs there. It is registered with my kindle device e-mail recognized.
When I try to open the Kindle app after selecting the Go Launcher EX, the app tells me that the device isn't registered. Would appreciate any advice on how to be able to open books and docs in Kindle and Android environments (if I'm saying that right). Thanks in advance.

I'm sorry, but when I open Google Play I only have the option "open" available on the kindle app...

[Q] Restore to Stock Kindle Fire

Are there any ways to restore the kindle fire to stock out of the box?
I saw one thread that talked about unbricking a kindle fire in the android development forum but i am not sure if it is the same, and it seems to not work for the people.
My kindle was rooted, and thats when the books stopped showing up, now it got unrooted by OTA update to 6.3.1 and i still cant get books to show. I dont know what to do.
I just want to start over with my kindle if possible and get back to the basics. Please help!

If your unrooted why not factory restore? And do you mean Google books? Don't think it will work on your kindle now that its not rooted? Could be wrong but I don't believe you have the Google framework on your device anymore . The kindle app should work just fine for books but different account unfortunately.

Read over this thread and see if you can sort out your "books" issue.
http://forum.xda-developers.com/showthread.php?p=25778125
Rooting shouldn't affect how your books are shown and it is more likely a software issue. If you still can't get it fixed or you are just unhappy with being rooted, come back and we can get you fixed up.

Thanks pooch!
I didnt even think about being able to do the basic factory reset. I was stuck with the thinking about how it is unable to be done while rooted.

[Q] Soft Navigation Keys Disappear on 8.4.6

I have a Kindle Fire HD 8.4.6, rooted with Hashcodes 2nd Bootloader guide and TWRP and Seokhun's excellent instructions. I am having a problem with the soft navigation keys consistently disappearing upon booting up. I have since restored my origional backup files, but retain the 8.1.4 bootloader and SuperSU.
Can someone help me retain the disappearing navigational keys?

When you came to cm from amazon os did you factory wipe? Also try clearing your dalvik cache and cache from twrp's wipe menu. If that doesn't work I'd redownload the ROM and check it's md5sum before flashing.

Thanks for your quick reply, Stunts. You and Hash and Seokun and the other devs are amazing.
What I think happened was that I experienced the disappearing soft keys (perhaps after downloading some software that tried to automatically clear memory and space ) and loaded a more user friendly android launcher, while trying to retain the amazon interface for my wife, which integrated with the recovery partition or root system of the boot.
I believe I resolved this (after 6 successful boots after 0 for 5) using Hashes 8.4.3 update @ http://forum.xda-developers.com/showthread.php?t=2142241. I am guessing that file updated the bootloader, which seems to have resolved my initial problem.
However, the "Upgrade Your Kindle " box is still grayed out. So, If I did want to go back to 8.4.6, what would you suggest?

Ah that button is usually greyed out, it's meant for if you follow amazon's instruction on their site and put their update file on your sdcard, if you do that then it would let you hit it. That method should still work I believe if you want to update it. Keep in mind that would unroot it and possibly get rid of custom recovery, but it's been a while so I don't remember if it gets rid of custom recovery, then again I just woke up and I haven't used amazon os for the better part of a year now.

I followed Amazons directions, placed the .bin file in internal memory, but the "Upgrade Your Kindle" box is still grayed out.

Did u ever at some point disable ota's?

You guys are awesome. After allowing OTA updates, with the update .bin file in internal memory, the Update My Kindle button was activated. However, 8.4.3 with the Holo launcher seems to be working great. Thanks so much!

[Q] Kindle hd 8.9 stuck in slow mode after failed re root

My kindle hd 8.9 was re rooted using bin4ry v31 after the last ota update 8.4.8. It worked fine. Now there was another ota update to 8.4.9 on 6/14/14. I tried using the same method as before. ADB is enabled in my kindle, I am seeing Android Composite ADB interface. when I plug the kindle in. I got through part of the re root, where it rebooted, and now it is extremely slow, has a black screen with white cracked lines to slide in open, and although some things work they are very very slow. Please can someone either help me re root or unroot it so that the kindle runs normally. I don't know what mode that slow one is, but you can't do much of anything. I tried to roo a few times, and tried to put in the stock kindle update and re run it, but nothing is working to get it out of the slow mode. Right now my computer can see and put things onto the kindle, and when trying to root, it seems like it is trying to work, but since the kindle is slow, I don't know if it is getting stuck and not finishing.
Can you help me figure out what is wrong?

Yep sucks for us for now it seems
Mine is in the same state. To unslow mo it all i found that works is using recovery mode to erase every single thing on it. This will speed it back up to normal. Beyond that i don't have a clue what to do.
You can enter recovery mode if you dont know how by pressing volume down and power. Or dl droid explorer run it click the multi colored shield icon and reboot to recovery.
I would hold off for now though. As one of these guys may have a way to save you all the head aches i have now. I had psp emulator playstation emu nintendo ds dolphin aka game cube and wii all running properly now all gone. go figure. Pain in the rear to get em all running properly. Oh worst bit loosing my crisis core newgame + save lvl 35+ with all items etc etc. Was gona put the hurt on every thing LOL
Oh and if theres any amazon employees lurking and reading great job on becoming a apple clone wanabe In other words amazon you all need to get a grip. People want to customize their tablets and have something that runs like mad with out regards to warranty. We want our tablets the way we want them not the way you want them. No one likes apple with their forced updaties etc

Factory reset is always better than flashing and other serious tinkering. kindle hd 8.9 is still rootable with 8.4.9 update, I did it and another member KatanAlive have done it.

What method did you use to root? There are a few different methods. used bin4ry v31 I used the old special option, then also tried the old option.

Ive tried various tools etc. While it seems i am able to get root i can not for example view the root directory in adb shell. I can kill any process under ps list even ones ran by root. Again the root directory shows as empty under ls. Running the superuser app that does show under apps seems t do nothing (im assuming this is because root is already active by this point) It does load but nothing in log window. Also it remains stuck running extremely slow. I can not install google frame work etc.
What i want to do is just go with a custom rom and be done with this mess. After all if amazon managed to force updates on kindles with ota disabled and blocked once they will likely be able to do so again. So theres zero point in staying on a stock rom even downgraded and or rooted.
Now the only problem there is it seems rom update requires fastboot? If this is not the case what are the steps to go about it by a different means? Or what methods other than fastboot cables are there to force it in to fastboot with out ripping in to the kindlefire hd 8.9 in my case?

I used manual method described in this thread and yesterday another member also used this same method to root the Kindle with update 8.4.9 http://forum.xda-developers.com/showthread.php?t=2069117
I have been extensively reading this forum for rooting Kindle Fire HD 8.9 and I have seen people failed just because of a simple mistake or not starting afresh. Many people were able to overcome their anomalous problem just by a factory reset and then starting again the process of rooting.
No one knows at which step problem started to appear until you clarify completely that what method you were following, or did you install some other drivers mentioned in another method, or did you interrupted the progress, or any other tinkering you had had done earlier with Kindle.
Every method pre assumes that your device is in default condition and your PC has favourable environment for the completion of the rooting process. Like a meber was following the process of rooting and when a stage came to enter his Amazon password, he entered the password but the process could not be continued, because his Kindle was not registered , so even after entering the correct password the process was aborted. Later he registered his Kindle and started agin and it was rooted.

So true what you've said about it not being a fresh root. I am going to try a few more times to root, then do a factory reset. My kindle could use a fresh start, but I thought I'd try just for future knowledge. If anyone else comes back from the slow kindle stage, please contribute what you've done to fix it because it may help someone else resolve their issues.

I decided to do a full restore. Then I was able to use a bin4ry script for kindles to root. Now I am having difficulty getting google play to work again. I keep getting an error not enough space on the partition \system. Free up 6MB in system and try again. I put a version of google market on to see if there would be a difference. I was able to open it, but nothing will download. Anyone else have any experience with this problem?

If you have rooted Kindle "not enough space" problem can be easily resolved. Is your Kindle rooted?

Yes my kindle fire hd 8.9 is rooted. I currently have version 8.4.9 software from amazon.

I too have had this low space problem after updating to 8.4.9. I was despaired but after searching the internet for 2/3 hours I found the solution. First thing you need to do is to get Titanium Backup from somewhere. It has the capacity to convert system app to user app and this will free up some ROM space so you can install Google Play afterward. Convert one by one some system apps that are not critical to Kindle's functioning, to user app. For example, you can convert Silk browser, Amazon Video, Amazon music, Kindle tutorial, Office Suite to user app. The moment you have above 20 MB free space in ROM you can install there Google Play. I am not sure if a free version of Titanium Backup have this functionality or not, I have installed a pro version of it. If free version is of no use then get a pro version from somewhere. I think you know where to get it from. Good Luck.

Wow thanks so much for the info. I did not have the pro version of titanium. Instead I used /system /app mover which is a free app. I changed a few system files to user files like suggested and am now able to use google play. I made sure I could download apps from it also, and it worked just fine. Now I have to re download apps I lost when I had to restore.
