[Q] [DOWNGRADE] Safe method to downgrade ? - Nexus 4 Q&A, Help & Troubleshooting

I want to downgrade my Nexus from 4.4.2 (Omni nightly) to 4.3.1 (any custom rom). I tried flashing 4.3.1 PSX but was stuck in a bootloop. So I want to know the safest method to downgrade to 4.3.1 ?

have you ever tried to format dalvik cache?
I don't think it is possible if you directly do that thru custom rom. since you have the updated version of os. I think the best way is to turn back your os to 4.3 first then you can have your custom rom installed.
but lets just see what others can say about it. I also have this problem when I tried to revert back my os directly from 4.4.2 to 4.2.2 using lewa os5.

Flash full stock first. You shouldn't have any problems.

Download and use the tool kit. It will guide you step by step. You can find it in the original development section.

I always use the recovery to downgrade, wiping data of course before flashing. The last downgrade that i've made was from 4.4 to 4.2.2 and i havent notice any issue after that...

Dey better hai toolkit mat use kar, CWM/TWRP se pura dalvic aur data cache wipe kar phir vanilla method laga ie. fastboot se stock image flash kar

Will my internal storage be wiped ?

Yes everything will be wiped. Google automatically backups your calendar, emails, contacts, Wi-Fi passwords, bookmarks for Chrome. However, things like sms messages, pictures, save games, music, ringtones or any other type of files stored on the nexus 4 are not backed up automatically. Make sure to backup those manually by using a third party app or directly coping it to your computer.

[Q] How would I go about updating in the future?

I have unlocked and rooted my Nexus 7 and it is also running the Motley kernel. When new updates come out for the Nexus 7 how would I go about updating without loosing my data?
Simplest method,
1. Backup ur data
2. download the latest update from Google.
3. Flash it and root it via toolkit or fastboot.
4. Restore data.
Its just like flashing new rom clan and efficient.

Not everything is 4.2 Stock I'm using Frank- kernel not the Stock one
don't have the stock one anyone more
also I am updated Sound to beats Auto Mod
Checked the boot Video to a Custom one .
Okay FIxed using N-Cry tool kit it will wipe everything so back up before hand
seriously? flashing stock 4.3 over stock 4.2.2 but with some mods will not work?
I understood it was possible but flashing instead doing OTA. is it true?
This is one of the reasons why I stay unrooted as I get OTA updates without hassle and without losing any data. No need to flash or backup anything.
No risk of bricking the phone.

If you are going to flash custom ROM; use a toolkit to Root it; flash custom recovery of your choice. Then copy custom ROM to ur phone; go to recovery and flash it. You don't need to downgrade your boot loader.

Does this mean we can downgrade from 4.3 to 4.2.2 custom ROM?
I'm not having a good time with 4.3 stock rooted and custom kernel and thinking about going back to CM 10.1.2. All I need to do is flashing the custom ROM in recovery?

Yes you will be fine. Before PA 4.3 rom was released, I was using Latest 4.3 bootloader with 4.2.2. I am going to revert to 4.2 as well. I noticed 4.3 battery is really good but sometime touchscreen doesnt response / volume buttons doesnt work.

for unresponsive screen go to 'developer options', 'hardware accelerated options', 'disable HW overlays' and select 'always use gpu for screen compositing'. Works for me but setting doesn't seem to stick on reboots.
^^ oh okay thanks but I am already back to the good old 4.2.2 .

Hi I´m quite new to this and did recently flash my second custom rom. I went from CM10.1 (4.2.2) back to stock image, and flashed
[AOSP]Official 4.3- S4 Google Edition- Finaly v2.0 - Feel the Experience of Nexus. The phone is running hot and I´m kind of dissapointed with the
lack of tweaks in Google Edition. So I´d like to go back to CM
So if I understand you right I can from 4.3 flash my stock image (from TWRP) which was on 4.2.2? Without worrying.
Did you make a nandroid backup when you were stock? That should be the easiest way to get back to stock. If you didn't then you will need to use odin to flash back to stock.

Can't flash new rom after flashing 4.4 rom.

I flashed a Kit Kat rom, and before I was having problems with recovery. Now I'm having problems flashing a new ROM. Every time I try to flash a different rom, it says it flashes but it just goes back to the 4.4 rom I flashed first. I can restore a backup just fine, but even from the backup it does the same thing.

My MAC address keeps changing after reboot, and wifi is screwy no matter what I do. Full Wipe, factory reset, Factory image restore. Its seems the 4.4 roms change things that cant be undone. I now have to have my phone replaced.
Gah. I'd rather not have to have my phone replaced. I feel as if its just 4.4 ROMs though.

Try reflasing your recovery. If that doesn't work, then flash the 4.3 factory images.

I'm on the latest CWM touch, I believe 6.0.4.3. I haven't actually tried going from the 4.4 rom to a 4.3, but I know I can't go from 4.4 to a different 4.4 rom, or from 4.3 rom to a different 4.4 rom, it just goes to the first one I flashed.

GooManager is telling me that there is no recovery available for my device. That's odd.
If all else fails, download the stock 4.3 image and fastboot flash it, then try whatever other ROM you wanted.

The only other thing you might try now is flashing any 4.3 or 4.2.2 ROM, reboot, and see if it's now on that one or still on 4.4...
Or is that what you already did with PAC?
You can also manually format /system then /data from TWRP or CWM then manually flash your new ROM.

That's what I did. I went from 4.4 to PAC, and it booted into PAC. Same with CM 10.2. It seems to just be happening with 4.4 roms.

I just wiped /system and /data, and now the 4.4 PA fails to flash, but CM 10.2 flashed. I'm gonna switch to CWM to see if it'll flash there.
UPDATE: CWM would NOT let me go back to the previous option when asking me to reflash recovery when booting, and it didn't flash PA, so now I'm stuck on the first 4.4 build with no GApps until 9 or 10 tonight. First thing I'm doing when I get home is flashing the factory image.

Did you do a full-wipe? If not, that's where I would start. If you did a full wipe, I would then clear cache. Also,could be a bad flash or download.

Were you using official KitKat? Maybe you'll have to flash 4.3 factory images. Just don't flash user data or recovery. You can boot to TWRP and wipe. Them you don't lose everything on your phone.
Did you make a backup?

Yes I was on official fact. image KK. I am now trying to flash 4.3 stock and unroot. Then root again. Maybe that helps.
KK radio/boot doesn't play nice with 4.3. I think you could've flashed an older radio and go 4.3.

Yes. The .84 or earlier are fine for 4.3. I use a hybrid to enable LTE for T-mobile US.
