[Q] how to go back to stock kitkat??

Spice Dream UNO (Android One)
i have unlocked the bootloader of my spice dream uno, philz recovery and im running the 5.1 phillipines version (i think so) of android 5.1...
Can anyone make a guide on reverting back to the stock kitkat for my phone as i got it on my first day so i can make the official OTA update to android 5.1??
I searched for this but it seems after reverting the phone ends up with some IMEI problems. so im asking here to make a safe guide for people out there including me using SPICE DREAM UNO to have a safe return to kitkat so we can make the official 5.1 update.

I might help you

See.... i know there might be many problems with SPflash tools to work with many users as u may have got many disappointments as i have got. I tried Running it but never get it done with sp flash tools... So i would tell you a fastboot method which you can do to restore your stock kitkat rom by some easy commands....
FIRST Of all ....
REQUIREMENTS:
1. You should have fastboot adb folder in ur pc...
2. STOCK ROM (sprout) google it you would find it in xda
PROCEDURE:
1. Go to fastboot mode in ur mobile (i presume that u know how to do that or if u don't know just google it)
2. Open the Adb fastboot folder
3. Press SHIFT+rightclick -> Open command window here
4. Copy the stock rom files into adb fastboot folder.
5. Check if your smarthphone is connected or not by typing: fastboot devices
6. Now perform these commands one by one:
fastboot format userdata
fastboot erase system
fastboot flash boot boot.img
fastboot flash bootloader bootloader.img
fastboot flash cache cache.img
fastboot flash logo logo.bin
fastboot flash oem oem.img
fastboot flash preloader preloader_sprout.bin
fastboot flash recovery recovery.img
fastboot flash secro secro.img
fastboot flash system system.img
fastboot flash userdata userdata.img
7. Now unlock your bootloader by typing: fastboot oem lock
or you could do this with All in one tool for our device
8. reboot ur device ... and voila..... it stock kitkat....

NO Update!!

its "fastboot flash preloader preloader_sprout.bin" anyway this method brought me back to kitkat. Thanks.
Now i go to about phone -> system updates and click "Check for update" it shows your system is up to date and the Last checked for update as the current time. Did Indian android ones(Spice dream uno) get lollipop update or not?? Why isn't the update available for me??

It is in a weekly manner...they are giving updates to a small number of users right now...but there is a news that....every android one devices would get updated by the new lollipop till 23rd of march...so wait for it for some more time......

Do you have twrp?
Have you tried flashing twrp if you don't have it installed?
Which ROM are you flashing?
It looks like you don't have enough space if I'm reading that error correctly
We need to know so we can help you

please help to solved it
my frimware is
XT1068_TITAN_RETAILDSDS_6.0_MPB24.65-34-3_cid7_CFC.xml
thanks

This is stock firmware, yes?
Are all your Moto G drivers up to date?
There are a number of different ways to install depending on the package type.
Some packages are flashable zips. Needs Twrp (Team Win Recovery Project)
Some are sideload packages installed via Fastboot.
Some are OTA packages (OTA, over the air) installed via phone update.

make sure you have motorola drivers installed https://motorola-global-en-aus.custhelp.com/app/answers/prod_detail/a_id/86934/p/154,153
make sure adb is up to date, you can use this https://forum.xda-developers.com/showthread.php?t=2317790
You want to flash stock rom again? You have to know, that you must follow exact steps, else it fails.
I would recommend you to re-flash stock ROM and if it still breaks after 3-5 days, you know something is faulty with your hardware.
-- re-flashing stock rom, will erase ALL your data + internal storage, backup all your data to SD first!
You can get latest stock rom for your device here: https://firmware.center/firmware/ make sure its xt1068 model and for your country/region
reboot to bootloader, connect to pc,
in cmd, type
Code:
fastboot devices
-> it should show your device, proceed:
Code:
fastboot.exe flash partition gpt.bin

fastboot.exe erase modemst1

fastboot.exe flash fsg fsg.mbn
fastboot.exe erase cache
fastboot.exe erase userdata
-> you need to follow exact the flashing steps, else it might fail! (if you have ...sparsechunk.4 or even .5 flash it also)
-> TWRP is a custom recovery. You dont need it, if you want to install a custom rom, you need TWRP.
peace & good luck!

Can you make a picture of your bootloader? And can you post me the name of the update you allways flash?
Im not sure, but that really sounds like emmc is faulty... I mean above method makes sure all is good with software, so can be only HW. Its typical, when itcomes to write to some damaged cluster of emmc, all gets f#+"ed up & it than cant start again. Hmm if it happens again, i would try to first format internal fully, maybe it gets fixed.
For formatiing internal storage, you need TWRP (recovery), to install it:
1. unlock your bootloader here: https://motorola-global-portal.custhelp.com/app/standalone/bootloader/unlock-your-device-a
2. download latest TWRP here https://dl.twrp.me/titan/
3. connect to bootloader then type:
Code:
fastboot flash recovery twrp-3.2.3-0-titan.img
after it flashes, choose "recovery" in bootloader using volume down. Volume up selects.
In TWRP enable modifies to system if asked
then in WIPE tab choose advanced & format Internal.
You can then reboot to system. Hopefully it goes well then.
If not, you can try install a custom ROM, but honestly, if the emmc broken it will probably not help.
Also if you are very experienced/know someone you could try located the exact location of broken clusters & then exclude them from filesystem, but this is very hard to examine...
Peace!

Thx. But i need a picture of bootloader screen, see my picture!
-> hmm in your case i would try it now with formatting internal completly.. But even better would be full formating, so when you have TWRP:
- format Internal storage
- then tick system + data + cache and format them.
- You have to reflash stock then OR (i recommend) try it with a custom rom, like you said allready tried stock many times...
To install custom rom, get these files
ROM: https://forum.xda-developers.com/moto-g-2014/orig-development/rom-lineageos-15-1-t3786749 get latest build
GApps: https://opengapps.org/ choose ARM -> 8.1 -> nano version
put everything in sdcard or storage (after wiping it)
Then in TWRP -> factory reset in wipe menu -> install ROM zip -> install GApps -> reboot. 1st boot can take some time. Test & report.
EDIT: I read in other threads who have the same problem, that they have a wrong recovery or things dont get flashed..
Did in commandline window, when you execute a command get a [OKAY] in terminal after EVERY operation?
EDIT2: Your rom file seems okay. If you are sure that you have xt1068, i would try it with formatting internal, see above. When you unlock bootloader, it will completly wipe your device! Backup stuff 1st!
good luck

So you flashed custom ROM -> it worked for 3 days normal -> then black screen (page) ??
When yes, probably something with your HW is faulty (most likely the eMMC has a bad block or something..)

Using Lenovo Moto Smart Assistant to restore stock rom (and lock bootloader after)

If you have some difficulties finding fastboot rom for some G5S+ variant, I suggest using Lenovo Moto Smart Assistant (LMSA). You can download it from here and install on your PC.
How to download latest specific stock fastboot rom for your G5S+
You must:
Using stock rom (locked or unlocked bootloader).
Install Lenovo Moto Smart Assistant on your PC.
Restore stock firmware, recovery, and boot image (if you changed it before).
Steps:
Reboot your phone to bootloader.
Open "Lenovo Moto Smart Assistant".
Connect your phone to PC using the USB cable.
Choose "Flash" menu on LMSA.
Choose "Moto Phone".
Choose "Moto G Plus (5th Gen S)".
Choose your phone models.
Wait for a minute while LMSA checking your phone, and then choose "Rescue". It will download the latest 1.5+ GB stock fastboot rom based on your phone model. You can find it on "C:\ProgramData\LMSA\Download\RomFiles".
Click "Rescue" to flash latest rom and accept some confirmations. Your phone will be rebooted after flashing process completed.
Now your phone is back to stock rom. Of course, if you have unlocked it before, those steps wouldn't lock your bootloader. If you want to lock it, I suggest you do it immediately after flashing process completed.
Here to lock your phone after successful stock rom restoration.
You must:
Have ADB fastboot driver installed.
Get extracted fastboot rom from "C:\ProgramData\LMSA\Download\RomFiles".
Steps
Reboot to bootloader.
Open "Command Prompt" on your PC, and go to the location of extracted fastboot rom.
Connect your phone to PC using the USB cable.
Check first that your phone is connected using "fastboot devices" command.
Do all below commands in sequence:
Code:
Code:
fastboot oem lock
fastboot oem lock
fastboot flash oem oem.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash system system.img_sparsechunk.5
fastboot flash system system.img_sparsechunk.6
fastboot flash system system.img_sparsechunk.7
fastboot flash system system.img_sparsechunk.8
fastboot flash system system.img_sparsechunk.9
fastboot flash system system.img_sparsechunk.10
fastboot flash boot boot.img
fastboot oem lock
Your phone will be restarted. There will be no unlocked bootloader message anymore. And you'll have your phone locked. Ta-da .
Note:
Check "system.img_sparsechunk.x" files (where "x" is sequential numbers) in extracted fastboot rom folder. Newer rom may have more files than the older one. You must flash ALL those "system.img_sparsechunk.x" files in sequence.
If you have issues, please share here. Thanks are appreciated.

I did all above steps but my G5 plus is still saying it has an unlocked bootloader with a ID: Invalid key error.
My phone simply avoids the bootloader to be relocked... it's just pure garbage...

What is the reason for relocking the bootloader? You don't get the warranty back...

should i setup my devices and come back to bootloader or without setup please clear this
thanks in advance

Will Moto Smart Assistant also work for the G7 (Play)?
Motorola support sais no (and that there is no way at all to restore the images after unlocking the bootloader)... will try to find out myself later today.
And another question, do people have experience with updating Motos via Moto Smart Assistant? Reason is that latest models (G7) do not allow for OTA updates with bootloader unlocked. Am wondering if it will still be possible via the Smart Assistant - provided that works at all

Does it require only stock rom?
Can i flash the stock rom using lenovo smart assistant when the phone is with custom rom?

Tried it all, but no good news.
Did it all, but my phone is stuck in boot screen. Can enter bootloader and recovery but can't do anything else. Tried everything I could find online (adb flash from twrp, fastboot flash [stock rooms, custom rooms]). Just keep getting kernel errors. If someone could please give me a light I would aprecciate a lot. This started after I installed lineage and tried to restore it back to stock via fastboot flashing (Potter retail 8.1), since fingerprint sensor stoped working on lineage. Mine is XT1802

Install Pixel Experience ROM

I am on Pixel Experience ROM and this ROM is purely copy of Android Pie of Pixel Devices and most stable rom
Prepare an sd card and copy pixel Experience ROM winrar file then put it in your phone and flash going into the recovery mode
This will work out for your device and will start up again

Bricked moto E5 plus XT1924-4 help

Good afternoon friends.
Sorry for english, courtesy of google tradurtor
My moto e5 plus xt1924-4, bricked after trying to install a rom, stayed in fastboot mode only.
After a friend installed the stock rom via fastboot the same again it worked, but the camera does not work and the device now only marks 1gb of ram, when in fact it has 2gb of ram, which left the device lately slow.
Note: on the fastboot the handset marks as SKU 1924-4 only with the name Hannah and not Rhannah which is its correct model.
Tb features 1gb of ram in fastboot now.
Thanks for any help you can give.

go here https://androidfilehost.com/?fid=11410963190603894295
download the latest firmware and go into fastboot and run the commands fastboot flash boot boot.img, fastboot flash bootloader bootloader.img, fastboot flash modem modem.img, fastboot flash vendor vendor.img, fastboot flash system system.img, fastboot flash oem oem.img, then reboot into recovery and perform a factory data reset and you should be set to go.

Device is corrupt. It can't be trusted and will not boot

Can't even fastboot flash boot recovery system...and thats all folks...waste of money.

No I installed Chinese v2.27.... Well it's absolute mess like I never seen Android before. Then attempted to flash global again, problems to the point of corruption. I have fastboot flashed all key elements of working Android phone multiple times. Can only get to fastboot after boot screen that I have to do manually. Recovery system is toast.... Guess it's back to Poco F1.... Learned my lesson from junk.

Just flash the ROM again..It will be back lm

Every time you restart back to the bootloader you need to do: "fastboot oem nubia_unlock NUBIA_NX629J" first

Guess it's back to Poco F1.... Learned my lesson from junk.

LMAO if you can't go from stock global to stock Chinese and reverse from the manufacturer with their recovery, you haven't got a prayer for custom roms or mods.

if you stuck in the Device is corrupt. It can't be trusted and will not boot and you are in the Chinese or global rom then flash the stock boot image via adb. well I am using a Chinese v2.27 rom with rooted +gapps and then realized that most of the google apps wont work correctly because of the unlocked bootloader. I tried to lock the bootloader via adb then the message "Device is corrupt. It can't be trusted and will not boot" show up. so I try to use adb to flash the stock boot image then it work. first place the stock boot image to the "Minimal ADB and Fastboot" folder which located in the local drive under program file(x86) then run the command
fastboot flash boot boot.img
fastboot reboot

Bud I put so much effort in last 13 hours to no avail....fastboot erased all partitions, reformatted, reflashed to no avail. Right now it just boots loops on Chinese 2.27 boot splash, I do have Chinese recovery though, but the same otg adapter and pen drive that works on 5 different devices, this damn phone won't read it so even that is out of the question. I wipe my hands clean of it, some things just best to put a bullet through it.

No BS, all I did was flash CN 2.27 over NA Global, after a look at the mess it was I proceeded to flash NA Global back.....no TWRP No Root with SuperSU or Magisk. But in fastboot it does say Root=1, so I guess the CN 2.27 rooted it by default cause I sure as hell didn't. One thing that is bothering me while in fastboot unlock bootloader I can't turn Secure Boot off which I believe is why it won't boot system.

all you need to do is to fix the corrupt image so later once you finish the first step of booting to the phone then you can flash to global rom. if you have the cn version 2.27 boot.img then you can download the adb and use the command to fix the phone

Shouldn't have messed with something that wasn't broken. Now you have a nice brick to use as a paperweight. Hope you get it fixed tho. Good luck.

Solved Instructions:
fastboot oem nubia_unlock NUBIA_NX629J
fastboot flash parameter parameter.img
fastboot reboot bootloader
fastboot oem nubia_unlock NUBIA_NX629J
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash splash splash.img
fastboot flash modem NON-HLOS.bin
fastboot flash system system.img
fastboot flash dsp dspso.bin
fastboot oem nubia_lock NUBIA_NX629J
fastboot reboot
*****as soon as boot screen appears hold volume + button, now in recovery...navigate to wipe data and then wipe cache....then plug in otg usb pen drive (formatted FAT32) with Rom package .zip....navigate to update otg in recovery select it let it do its thing and walla your phone is fixed.
*****if you ever go from CN rom to Global rom you must Wipe Data and Cache through recovery, it is not enough to do it in fastboot and your device will remain soft bricked.
