Switching between 2 custom ROMs - Huawei P9 Lite Questions & Answers

If I'd like to flash a new custom rom, what's the procedure?
Flash stock vendor, wipe system, data, cache + dalvik, flash rom + gapps?

A) when you are updating to a new build of same custom ROM, u can continue with 'dirty flash' : clear cache/Dalvik (Don’t WIPE data) » flash the ROM update files/ Add on zips » Clear Cache/Dalvik » Reboot system.
B) A 'clean flash' should be performed when you are changing to a NEW Custom ROM. The sequence: go to TWRP » Wipe / Factory reset » flash custom firmware and kernels(if any) » Flash the new Custom ROM zip files(GAPPs) » Clear Cache/Dalvik » Reboot system.
Good Luck!

Alright but don't ROMs usually modify the vendor partition? Also, my problem has already been done.

Small Success Story

I was on with Kingdroid V2.0 with S3 addon. Kernel Speedmod#3.3.
I flashed Criskelo V7 as follows- None of the steps belongs to me-All gathered from this forum, thanks to concerned member/s.
1- download AbyssNote kernel 4.2 (for CWM), Criskelo V7.ROM in SdCard
2- reboot to recovery mode and install AbyssNote V4.2 original touch
3- don't leave recovery , Go back to advanced then reboot recovery
NOW THIS IS TOUCH SCREEN ONLY (buttons will not work)
4- wipe data/factory reset…yes--delete all user data
5- wipe cache partition…yes--wipe cache
6- go to advanced and wipe dalvik Cache…yes--wipe dalvik cache
7- Go back
8- go mount and storage
9- format /cache…yes--format
10- format /system…yes--format
11- format /data…yes--format
12- Go back
Now Flash Criskelo V7 Rom
After installation completed, the phone automatically rebooted into CriskeloRom. Working Nice. About the Phone-Build Number IML74K.XXLQ3 Kernel [email protected]#3.Rom Version CriskeloRom Note ICSv07.
Now I would like to know whether shall I keep this kernel or flash kernel speedmod #3.3 over this kenel. suggestions are appriciated.
Ask the dev which kernel it is.
I think it probably is CF Root kernel.

[Q] Can't upgrade JORDN_U3_97.21.51.sbf

Hi, my Defy (Green Camera) is stuck on JORDN_U3_97.21.51.sbf - strange chineese Eclair ROM - screenshot here http://forum.xda-developers.com/showpost.php?p=27590063&postcount=4.
I installed it after my battery died during updating Cyanogen to newer version - I panicked a bit and needed working phone asap, so I used mcGyver hack and flashed it with RSD Lite as I found in some guide.
Now I want to install any better system on top of it (it's real crap - all google apps crashes immediately for example) Cyanogen 10+ would be best.
There are some similar threads, but they wanted to downgrade system, not upgrade.
http://forum.xda-developers.com/showpost.php?p=14762402&postcount=143 - I didn't tried it yet as download pages
looks suspicious. //edit: downloading it, but it's really slow.

What I tried to do so far is:
I. Rooting phone with SuperOneClickv2.3.3-ShortFuse
II. Installing SndInitDefy_1.4_2.apk
III. One of following:
a)
1) Go to Custom Recovery.
2) Wipe data/factory reset, wipe Cache and go to Advanced ► Wipe dalvik.
3) Go to install zip from sdcard ► Choose zip from sd card.
4) Flash cm-10-20131030-NIGHTLY-mb526.zip
6) Wipe Cache and Dalvik again
7) Restart.
It didn't boot in 10 minutes (Motorola logo) so I flashed sbf again and returned to I.
b)
1) Go to Custom Recovery.
2) Wipe data/factory reset, wipe Cache and go to Advanced ► Wipe dalvik.
3) Go to install zip from sdcard ► Choose zip from sd card.
4) Flash froyo kernel
5) Flash CM10-20120924-NIGHTLY-mb525.zip.
7) Wipe Cache and Dalvik again
8) Restart.

c)

4) Flash froyo kernel
5) Flash cm-72-20120921-NIGHTLY-Defy.zip
7) Wipe Cache and Dalvik again (recommended).
8) Restart
It didn't boot in 10 minutes (Motorola logo).
I also tried some other Quarx builds, some times with gapps and RLRv2.16_base.zip but I don't remember details.
Any ideas what can I do? Now i'm trying downloading various roms and trying to install them with recovery.
EDIT:
Now I have DEFYPLUS_U3_4.5.1-134_DFP-231_GR_SIGN_UCADEFYEMARAB1B80AA004.0R_PDS03C_USAJRDNGIBRRTCEE_P022_A022_Service1FF.sbf which works, but I cant root it - zerg rush fails
Well.. After I flash something I don't wipe cache and dalvik , this maybe should be the problem..Before I install something I do a data/factory reset , wipe cache , and then wipe dalvik. You should try after you install something don't wipe cache and dalvik..
OK, i fixed it.
With DEFYPLUS_U3_4.5.1-134_DFP-231_CEE_ROOTED_No_Signed.sbf from http://forum.xda-developers.com/showthread.php?t=1542956 i got root, after that i installed SndInitDefy_2.3.apk and was able to flash CM10.

How to flash official ROM zip?

My friend's device has TWRP 2.8.7.7 and CyanogenMod 12.1 by @ED300 (not up to date).
She wants it to be restored in its original state. How could I flash this file?
Code:
http://phonedl.ota.lenovomm.com/dls/v6/Kraft-A6000_S058_151030_KK2L_WC67.zip
Should I just wipe system, data, and cache in TWRP then flash the zip from the link?
1. Reboot into recovery.
2. Wipe the normal way (Factory reset).
3. Flash the .zip.
4. Wipe cache and Dalvik cache after flashing, just in case.
5. Reboot. Enjoy!
Using TWRP? Don't I have to wipe system first when coming from another ROM? Thanks,
You have to wipe system, data, cache, dalvik cache
For me that didnt work you have to extract stockrom.zip then extract system.zip then take boot.img and flash it first, followed by system.zip and yourcountry.zip

Custom ROM Installation (TWRP)

When I touch reboot>power off button, TWRP is asking me to install TWRP
Should I Swipe to instaal TWRP app?
Booting is still working with Stock ROM, transferred Gapps & Custom ROM
Lenovo Recovery System Installed
Lets organize everything to someone that will help me
1. Installing TWRP
- When I typed the command <fastboot reboot> TWRP boots successfully, but when turn off Lenovo Recovery System boots again
2. Wipe data
- Which option do I need to select? Wipe cache, dalvic cache, system, data
- Can I just go to Install option and choose Custom ROM from device storage, without Wiping data first?
- If I select wipe data first it won't be erase files <Custom ROM & Gapps> from the actual OS?
Thanks !:laugh:
