I've tried to root my bush spira b4 with kingroot, kingo root pc, framaroot and i have had no luck. Then, i tried making my own custom recovery but it required a boot.img file. I tried backing up my rom to get the file but it said it couldn't as ii have an unkown rom structure. Other methods require root which i don't have. I searched for custom roms, stock roms, recoveries, but nothing comes up. please help! :(
[Fire Q&A, Help & Troubleshooting] phunni:
My kids are currently sharing an Amazon Fire tablet, which I've rooted and installed stock Android on to. I was planning on getting a couple more since they're so cheap and then they wouldn't have to share, but, from reading around on this thread, it looks like they're not rootable any more - is that the case?

It seems as if it requires rolling back the version and that Amazon have done something to prevent that and cause it to brick devices. I really hate Fire OS and only want to do this if I can get stock Android on the tablet...
[Fire Q&A, Help & Troubleshooting] sd_shadow:
depends on the firmware version, in most cases, downgrading will brick the Fire
[Fire Q&A, Help & Troubleshooting] mstrakt:
Like I posted in a different post, I just bought a fire tablet 16gb ($59.99) yesterday (5/2/17) at best buy and it came with OS ver 5.1.3 which auto updated itself to 5.1.4 only and nothing higher (thank goodness). Was able to downgrade to 5.1.2 and achieve root.

So I guess your just going to have to purchase one and hope it comes with FireOS <5.3.2.1. (5.1.4, 5.1.3 and 5.1.2.1) and if your lucky, follow these steps like I did https://xdaforums.com/amazon-fire/general/root-fire-7-5th-gen-2015-fireos-5-1-3-5-t3471395

Good Luck!
[Fire Q&A, Help & Troubleshooting] sd_shadow:
did you try rooting 5.1.4?

guessing it is now also rootable by kingroot
[Fire Q&A, Help & Troubleshooting] mstrakt:
Well, I had to downgrade to 5.1.2 from 5.1.4 using this guide https://xdaforums.com/amazon-fire/general/root-fire-7-5th-gen-2015-fireos-5-1-3-5-t3471395 Then I was able to root with kingroot (took several tries), block OTA updates, remove lockscreen ads, remove FireOS launcher and replace it with Nova.
[Fire Q&A, Help & Troubleshooting] sd_shadow:
yes, but that's 7 months old, things can change at anytime
[Fire Q&A, Help & Troubleshooting] mstrakt:
Sorry misunderstood your question the first time. No I did not try to root 5.1.4. Just followed the guide to a tee. Didn't want to higher my chances of bricking the new device. haha
[Fire Q&A, Help & Troubleshooting] phunni:
In the Fire HD forums there are claims that simply downgrading to an even earlier version (4.5.3) allow rooting - are the devices really so different that this wouldn't work on the standard fire? I bought a couple more tablets, but they appear to be running 5.3.3.0
[Fire Q&A, Help & Troubleshooting] DB126:
Yes they are and yes you will brick a 5th or 6th gen device downgrading FireOS 5.3.3.x to a lower rootable build.
[Nexus 5 Q&A, Help & Troubleshooting] aciupapa:
Hi. I grabbed my small 1000mah powerbank, and a Li-Po battery from lenovo a7-30h (flat battery), that is 3.8V and 3550mah

What i've done:

1. desoldered 1000mah cell (3.7V 18650 cell)

2. removed protection and regulator board from lenovo battery (so that i had only + and - terminals.

3. soldered powerbank circuit to battery terminals

Now i'm charging the battery , i tested it. it charges phone and powerbank is also charging. I have a question tho. Is it safe to use it? I'm like,.... i soldered wires solidly, insulated it correctly, so that it wont ever short circuit on its own.

And is it ok, that i replaced 18650 3.7V cell with flat battery 3.8V min and 4.35 max? Will the battery charge fully?
[Nexus 5 Q&A, Help & Troubleshooting] dgm_mixtoon:
Upload pictures please :)
[Nexus 5 Q&A, Help & Troubleshooting] daedric:
You could run 10s 18650 in parallel, and get 200000mah, it wouldn't matter. Your protection lies in the original powerbank circuitry, and no matter how many cells you use, and how good they are, and how nice you solder them, it will never make it better than it was before.

Question, how many A can it output ?
[Nexus 5 Q&A, Help & Troubleshooting] aciupapa:
It outputs 1A :/ I guess i'll just pick up one of Ankers Slim powerbanks (10000mah) . It will be far less bulky and safer

2. Should I continue to use this CN Rom and do OTA with VPN enabled or

Flash any specific Indian ROM in any specific method to get the services.

I think the seller has unlocked the bootloader.

But there is no custom recovery installed and there is no SuperSU and not sure if the bootloader is locked or unlocked.

(I'll check on this and will update the scenario)

Please help

Also please provide links to flashing guide (CN Rom)

Assuming you flashed Chinese stock 1.9.044 already,

- Flash Stock ZUI_2.0.093 using QFIL

- Install FlyVPN and connect to any China server eg. Shanghai

- Open updater app and check for updates.

- Update to 2.0.133

- Connect to FlyVPN Chinese server again and check for updates.

I have an S3 I can use to transfer the .zip CWM file to the SD card of the S4, if I had the .zip file. I have no way to a computer to do anything like that, that way. The I'm Samsung Leiss? (I think) to restore it back to the factory version.

Thanks for answering. Appreciate it a lot.
[Galaxy S 4 Q&A, Help & Troubleshooting] MigoMujahid:
If you mean that you can use a s3 backup on the s4, then no, don't do that, i believe you can flash the stock firmware using your phone by MobileOdin or Flashfire apps...i guess, but i never tried them so i wouldn't recommend, if you have CWM recovery installed, you can try flashing a stock based ROM from development thread(if you like TW ROMs), you can also flash any custom ROM available for your model in the development thread.

You have to remove SD card and go to storage and click SD card forget! otherwhise it will say you don't have enough storage as the device is looking for your SD card. It has to convert to looking to internal memory. After doing this the update process will be fine.

[Samsung Galaxy S8+ Questions & Answers] d.cortez:
interested to know if this will work on an international device...
[Samsung Galaxy S8+ Questions & Answers] Flame Red:
Thank you.

In CSC_OYN_G955UOYN1AQC9, I see /system/omc/ATT which was not present on the phone I have. I extracted and copied that ATT directory to the phone and changed the directory permissions to 755 and files to 644. There was a omc/ATT/res directory but that contained ring tones and the death star power on and shutdown screens - so I did not copy any of that crap to the phone.

Rebooted. Placed a phone call and I expected to see a Volte icon up on the status bar. No joy. So I assume there is something more to it. This was on an international S8 plus "F" model.
[Samsung Galaxy S8+ Questions & Answers] d.cortez:
did you enable VoLTE under settings? (didn't see it mentioned above) also, do you have to change the sales_code.dat and sales_code_list.dat files to show "ATT" in the OMC directory and also in the build.prop file?
[Samsung Galaxy S8+ Questions & Answers] Flame Red:
Sadly, Volte did not show up under settings.

I am not sure how one edits those dat files. I did not see any references to any of this in Build.prop. I did see that the references to ATT were missing under SW_Conifiguration.xml. So I went ahead and copied sales_code.dat, sales_code_list.dat, and SW_Configuration.xml from the CSC_OYN_G955UOYN1AQC9_CL10895874_QB12856072_REV00_user_low_ship_MULTI_CERT.tar.md5, changed permissions and rebooted.

Nothing new in settings. Still no volte icon in the status bar during a phone call.

But reading the S7 thread here: https://xdaforums.com/s7-edge/development/17-03-26-renovate-edge-beta-1-sm-g935f-t3339149/page524, they indicated that there was no Volte in settings in Nougat, and one person said that it started working a few hours later somehow. Maybe one just has to be patient. There is also lots of posts there about having to call ATT to get it enabled if you don't get a phone from them.
[Samsung Galaxy S8+ Questions & Answers] saharmali:
Are you looking for the thread
[Samsung Galaxy S8+ Questions & Answers] d.cortez:
i have VoLTE settings with Renovate 1.1 ROM, however, no indication it's working. will follow the same steps you did AND call ATT asking to change the IMEI to an ATT phone that's capable of VoLTE and see if i can get it working.
[Samsung Galaxy S8+ Questions & Answers] Flame Red:
I think you are on to something. I went on to the ATT web site and looked at another phone I have where Volte and WiFi calling work and the web site lists "AT&T Call Protect" and "Wi-Fi Calling" where as the phone I was trying to enable did not.

The nice ATT agent said she enabled it for me, but the web site does not yet show it so I'll assume it needs time for the back-end to update it.

So I put these same files back (listed above) that I had extracted previously since I restored and changed the permissions again and rebooted. Nothing new appeared in Settings as I hoped WiFi calling switch to show up. I tried placing calls but no Volte ICON on the status bar.

I'll wait a few hours and try again. But reading the S7 Volte threads, I do believe you need to have the carrier enable it and the CSC files. But there are probably other stuff to get things to show up in settings. I just don't know what else.
[Samsung Galaxy S8+ Questions & Answers] d.cortez:
i copied all the files to the appropriate folders on my phone and upon reboot, saw a message saying Android is upgrading. still no indication of VoLTE, i'll give ATT a call as well. i'm going to look at the ATT build.prop and compare to mine to identify changes. i also read that the USERDATA file included with the OEM Samsung Stock ROM might be required on your device as well. maybe [MENTION=5899304]Tkkg1994[/MENTION] can incorporate into his ROM (although i haven't been able to successfully flash to my phone). :fingers-crossed:

[Samsung Galaxy S8+ Questions & Answers] d.cortez:
I'm using the Renovate Ice 1.1 ROM; the screenshot below is what I see in Settings>Connections>Mobile networks. The 1.1 ROM is using the DBT CSC code vs. the XEG that mine came with (Dubai/Middle East version). Also, looking at the Exynos ROM and the U ROM it appears that multiple CSCs are included in both ROMs. I can't recall where, but I remember reading that the USERDATA section of the stock ROM has something to do with applying the correct CSC.
[Samsung Galaxy S8+ Questions & Answers] `SBR`:
Mine is Tmobile and set the DBT as CSC, i can't find the VoLTE option as like you.. (DBT/DBT/BTU)..

also for S8, the files are kept under OMC (not CSC, thy have changed), you can extract the files from CSC of your file and move the file to Sys. (may be additional files required)...

to reflect the correct CSC, using root explorer go to /efs/imei/mps_code.dat and edit the CSC you want (make sure the respective CSC folder already available in OMC Folder).. refer this guide.

https://xdaforums.com/note-4/help/guide-to-change-csc-root-rom-multi-csc-t3017207

take a backup of efs directory before modifying the guide. find the below script to backup using ADB shell. (credits to [MENTION=5899304]Tkkg1994[/MENTION])

create a Folder in internal storage as "EFSBackup" before executing the below script.

Note: i tried with Tmobile OMC file and get Phone and Wifi calling FC, so it works half way but don't know how to make it fully.
[Samsung Galaxy S8+ Questions & Answers] d.cortez:
followed your steps and there were a few changes that made my 955FD appear that it has all the ATT services, including Enhanced LTE Services, WiFi Calling, Video Calling (dialer now has a call and video call button), ATT cellular icons and assume its an ATT CSC. see pics below. now, i still can't complete a Video Call and WiFi calling is disabled. key steps i followed:

use the above script to create an efs.img backup

i pulled the CSC from ATT's ACQ ROM

copied the ATT folder from the /system/omc folder in the ROM to the /system/omc folder on my device

set the appropriate permissions for folders and files

made backup of my OMC folder

copied CSCVersion.txt, sales_code.dat, sales_code_list.dat and SW_Configuration.xml from /system/omc/ATT folder to /system/omc

rebooted and the above changes appeared.

clearly something else is amiss, but i'll keep researching. @`SBR` thanks again for your tips...

I had the original Full_Odin_G955USQU1AQC9_Files.zip file on a Windows 10 PC and installed 7-Zip. If you open up this file directly under 7-Zip, you can then extract the files from CSC_OYN_G955UOYN1AQC9 as it can open some of those ext4 files (not all). Go down the directy tree until you find them. Copy them to your PC, then copy to the phone via USB. It is a pain to change the permissions. Total Commander can do the permissions changes, but it is still painful.
