crDroid is designed to increase performance and reliability over stock Android for your device also attempting to bringing many of the best features existent today

Features:

https://github.com/crdroidandroid/crdroid_features/blob/13.0/README.mkdn

How to Install(Follow All Instruction)

(Dont Report Bugs if you dont follow below Instructions)

Android 13 Release Notes/Installation Guide

1. Clean Flash

• Clean flash is mandatory: you are required to backup all of your existing data to your computer or your preferred cloud service and avoid using nandroid backup.

2.Flash TWRP

• Flash the new TWRP Recovery made by Zeelog : ( Mandatory)due to various changes in fstab file and encryption implementation, you are required to flash the new TWRP of which the link is undermentioned

Link

3. Wipe and format Device ( Both are different)

• After you flash and boot into the new TWRP recovery, format data and reboot to the recovery again.

Now, wipe all the partitions (i.e. system, vendor, data, internal storage). Wiping Internal might throw an error because of missing /data/media/ which is okay, reboot to recovery again.

This format data and wiping of other partitions is required only once every clean flash.

NB : encryption is now enabled by default and that is why a clean flash would cost you a data format.

4.Flash ROM and Gapps

*To use internal storage for transferring files from PC

From TWRP > tap Advanced > Terminal > run command: mkdir -p /data/media/0/

• Copy the latest releases crDroid Android 13 rom and latest NikGapps (optional) (core edition is preferred) to your internal storage/otg media/sd card etc.

Flash the rom + gapps (if you need) using the usual method.

thanks for the rom much love.. i almost tested all 4.9 roms on my mido.. among thrm CrDroid had best customization and LOS had best ram management and lightness ..im curios RAM management is on ROM or Kernel ? cuz all of thrm had FF kernel ..
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] kimoVoid:
are you gonna keep updating this rom? i dont wanna switch roms every 2 months bc they stop updating
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] KamiKaonashi:
Ram management is based on kernel and rom, i ship my roms with battery efficient kernel (darkmoon) but you can flash any 4.9 kernel
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] KamiKaonashi:
Yes, i will keep updating :)
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] st4ik:

[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] hungviet249:
This ROM is suitable for my Mido phone 3GB RAM / 32 GB ROM? Thank you very much
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] BigDaddyUnique:
why not ?! this is amazing ROM .. However i prefer to use LOS on 3GB variant due to less memory
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] hungviet249:
Thank you, ROM LOS is better than Pixel Plus UI, i'm using ROM Pixel Plus UI, andr11 but it's too slowly and lagging :((
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] BigDaddyUnique:
go get for this one or LOS .. both are A13 and good
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] st4ik:
How can i increase the zram to 2GB?
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] BigDaddyUnique:
Zram is not like Swap.. its not partition. Size of ZRAM is size of RAM that get compressed. So you get "more" RAM but it is slower a bit for the time needed to compress and uncompress.

Zram/SWAP/Paging is useful untill some point .. since it has CPU process overhead and slow storage R/W speed it WONT improve performance in all scenarios ..
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] TheHeretic:

2. navigation buttons appears even though they are turned off
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] Isa Daud:
After try crdroid android 11 for couple days, now i've been successfuly flash crdroid 9.3 to my Note 4 3/32gb version.

My conclusion after couple minutes, crdroid android 13 run smooth too, tap to wake less sensitive than crdroid android 11. I need more repeat tap to wake the screen.

Crdroid 9.3 also need ±3 gb space for system, and crdroid android 11 need ±7gb for system..

I hope i can get crdroid 9.3 update without formatting all installed app and settings.

Thanks for the dev.

Sorry for my english.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] Isa Daud:
I have same spec with yours and using this rom.

It's worth to try.. it's run smoothly, save space on system partition, and battery life also good.

[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] lucienchlin:
Big thank to KamiKaonashi.

Using camera app when performing zoom-in or zoom-out might cause freezing, or changing the focus target in tghe camera app might cause freezing sometimes. This happens in all camera apps, including the original one and Gcam or other camera apps from the google play.

Otherwise this rom is smooth and stable to me, this is what I found so far.

Best,

I'm having an issue with location, most apps aren't able to get my location at all. I have basic Gapps installed and all permissions are fine. How can I fix this?

[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] kimoVoid:
Camera keeps crashing a lot, needs a fix asap. Also, the whole UI starts lagging when there is music playing and you pull down the quick settings (probably due to the music player widget), it would be nice to get rid of that lag.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] dannyleone:
Hola. Tengo esta ROM. La cámara no es la oficial, eso parece. Se bloquea tras echar 2 o 3 fotos. No hay posibilidad de implementar la cámara nativa?

Great rom so far, only problem i have is that the weather widget doesn't work.

Is there a performance improvement with the FrenziedFlame or the DarkMoon Kernel?
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] yellowbossman:
Im on note 4x snapdragon crdroid 9.8 and darkmoon 4.9 run fine some issue with camera. however when I installed latest 9.10 version there is strange line at the bottom bugging. and I didn't see kprofiles in 9.10 which helped to switch between battery balanced and performance and was handy in status bar on 9.8.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] mac@xda:

why k profiles was removed from this rom on notification menu? it let me choose between performance, battery and balanced in previous version...

I removed since it has no real impact in performance and/or battery

The power supply checked for everything, is there a way to force it through Key or reset, suddenly the device turned into a brick, it turned off and that's it
[Android Head-Units] Anton TNT:
Hi, please write in English only !

You have probably problem with canbus box, or something is happened with it during car shutdown.

Disconnect canbus from device and start engine without it.

Then shutdown engine and reconnect canbus and start car and see if works again.
[Android Head-Units] Jelosia:
did, even threw another canbus
[Android Head-Units] Anton TNT:
check wires and cables behind if damaged or loose, check also fuse if not burned
[Android Head-Units] popamor:
what was the MCU version that you had?
[Android Head-Units] Jelosia:
repaired in the service, the power connector was badly soldered to the board
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Wal6512:
Yesterday night, I've successfully rooted my phone (wich i was really proud of after not realizing for an hour i was using the wrong twrp version).

Well after using it for a bit and getting all my backups over it, when I started Huawei health my phone froze, heated up and afterwards rebooted.

After trying to start Huawei health again, it worked fine but after some time the same things happend again. Well that lead me to uninstall Huawei health, wich i did but afterwards my phone started to freeze randomly. I tried to reproduce it after restarts but it seemingly was random.

So After that I booted my phone into save mode to see if the problem was dependent of the software. In save mode, my phone worked perfectly fine.

This left me thinking, its not a problem with the software, more like a problem with an app but since Huawei health was uninstalled i couldn't call wich app it could be.

The last thing wich i can do (or so i think any other ideas are always welcome) is to longtrace my phone and maybe find out with that what the error is but since i never used traces i am not quiet sure if that would help or even show what's wrong.

Anyone ideas what could cause this?

SPLs for DREA100 & DREA110

About SPLs

This thread contains information and downloads for SPLs for the HTC Dream (aka T-Mobile G1 and ADP1). What is a SPL? The SPL, or Second Program Loader, in conjunction with the IPL comprise a device's bootloader. Aside from bootstrapping Android, the bootloader also fulfills various diagnostic functions. One of these functions is the manipulation of data in the device's internal flash ram. Depending on the SPL installed, the user can apply a signed NBH file, flash nand images, and more. Note that the SPL is installed and operates independently of the Android build that runs atop it.

Currently there are three SPLs available. The G1 variant is the SPL that is installed in stock T-Mobile G1 phones. The Engineering variant is found in the Android Dev Phone 1. Finally, the HardSPL is a modification of the Engineering variant by cmonex, with additional hacker-friendly functionality. HardSPL is the recommended SPL.

Installation

The SPLs are packaged in the familiar update.zip format and install from the recovery console in the same fashion as other update files.

0. This is only verified to work for DREA100 and DREA110 devices. If you have a US or EU G1, it is most likely compatible. To check, boot into the SPL and confirm that the first word is DREA100 or DREA110. Please do not attempt to flash a SPL onto a Dream that does not fit that description!

1. If you are installing onto a G1, your G1

must

already have been "rooted" or otherwise have test-keys installed. ADP1 is exempt from this.

2. Download the desired SPL zip file (attached below), rename it to update.zip and copy it to the root of your sdcard. As usual, remember to use a USB cable with a ferrite core and dismount your USB drive before disconnecting.

3. Reboot the phone into recovery console and flash the update with Alt+S.

4. To confirm it has installed properly, power on the G1 with BACK + END to enter the bootloader. When you are done, press CALL + MENU + END to leave the bootloader.

5. To revert a G1 to its factory original SPL, simply apply the G1 Original SPL file.

[G1 Android Development] mack:
awesome. anyone wanna try it first? I hope this gives us access to the bootloader?

anyway Dream_kill is probably one of the luckiest guy to recieve one as a replacement from tmobile. He should buy the lottery. lol
[G1 Android Development] Stericson:
I just did it....no problems yet......

The update went really really quick.....

Woohooo...No problems! I see android skateboarding!

Thanks alot dream_kill, cmonex and JesusFreke,you guys are awesome!
[G1 Android Development] JesusFreke:
I've tried it. It works. :). Read the warning though, if something goes wrong during the flash, you'll probably have a brick.
[G1 Android Development] card13:
Whatcha think, another couple of weeks before us unlucky ppl that got the official rc30 can have at least root? haha, thanks google you guys finally came to our rescue. and t-mobile thanks for your mistake!
[G1 Android Development] hetaldp:
I am still helpless!

Was Busy around some Issue Developers G1 is a Welcome though but would be Happy if they had allowed Official RC30 to Developers Edition after voiding Warranty also. Hey Google Are you Listening

Edited: on 1-1-2008 New year gift

Thanks ti RC29-NBH file I have root now on OTA RC30 and now converted phone to ADP1
[G1 Android Development] neoobs:
Big question... does this change your build type?
[G1 Android Development] tmrepp:
...kernel version now says...

2.6.25-01843-gfea26b0

root@carrier #21

build number says

kila-user 1.0 tc4-rc30 116143 ota-rel-keys,release-keys

...didn't check what they were beforehand.
[G1 Android Development] jashsu:
This only affects your bootloader (specifically the second program loader). The software stack above that (kernel and userland) is unaffected.
[G1 Android Development] LvDisturbed1:
Great news...can't wait till someone figures out a way to get this on RC30(stock).
[G1 Android Development] neoobs:
you really never know... for all we know it gathers that info from the bootloader.
[G1 Android Development] popsi:
Could this update be applied to a phone running the TC5-RC8 (JesusFreke version) Since this update only affects the bootloader I should be fine?
[G1 Android Development] korndub:
hey JF, if I install the engineering bootloader, can i put the stock bootloader back?
[G1 Android Development] UnkzDomain:
I'd like to know the same...
[G1 Android Development] hmepas:
Done. Worked ok. Now the main question.

After I installed developer boot loader, do that means now what even if i'll install Official RC30 now, I still will have ability to reflash my system with modified.

The answers is 100% yes for me. But just to be 101% sure i am askin it.

Also. When I am booting with Camera+Power and getting those geeks on skateboards. It's said "no image" which image it's searching for? Where it's should be placed? Anything else what I could do from this "booting" mode?
[G1 Android Development] hmepas:
And another question. Google should have it's own version of OS (/system) for developers phone, beside of "official rc30 for t-mobile, which have root blocked" is this native version published anythere?
[G1 Android Development] Disconn3ct:
To do anything with it you need the fastboot tool (built as part of the source tree). There is a cheat sheet up at www.gotontheinter.net that talks about how to use it.

As to the google official build... source.android.com. Although they are talking about adding a way for devs to install the closed source google apps.
[G1 Android Development] darek214:
what is the benefit of having this over the modified RC30?
[G1 Android Development] Disconn3ct:
In addition to, not instead of.

It lets you (safely) work on the kernel or platform. That is all really.
[G1 Android Development] darek214:
so if im not a developer there is no real benefit for me to upgrade to this version?
