[Q] possible to update to stock GB and keep Froyo kernel? - Milestone 2 General

As per the title, is it possible to update the the latest stock UK GB, without updating the kernel? I have read the new kernel does not really provide any advantage over the Froyo kernel and want to keep the option of moving to custom roms. I know it possible to run some custom roms with the GB kernel, but just want to keep options open.
Cheers.

I think, you can use GB kernel, but you should not flash GB SBF...
So if you want UK GB with possibility of custom roms and downgrade, you can use /system nandroid backup I think.
But I'm not 100% sure, so please someone confirm or falsify my post

Dunno.
ROMs compiled against froyo kernel don`t works with gb kernel (libs and modues incompatibility?), so I don`t think it will work the other way :|
But maybe /system backup of RetailGB can boot with china-gb-kernel

Hmm... probably you are right. Anyway, here is UK GB nandroid backup http://forum.xda-developers.com/showpost.php?p=19926327&postcount=408 by santiemanuel, so someone could do some experiments

feel free ;D

I think I'll give upgrading a miss for now, will just keep an eye on the development forum. Don't really have much time to be experimenting
Thanks for the information.

So according to this two posts http://forum.xda-developers.com/showpost.php?p=21073056&postcount=30 it should be possible http://forum.xda-developers.com/showpost.php?p=21074131&postcount=32

I think the best thing would be if someone can create a stock UK GB system backup but pack it with the CH GB kernel. May be a flashable zip.
That would be the best combination in my opinion for all those still on Froyo kernel.
CH GB kernel will give an option to downgrade to stock Froyo. At the same time, it will get rid of the multitouch bug (CH GB kernel does not have that bug as reported by tezet) and allow one to flash even newer custom ROMs like CM9 and the upcoming CM7 based on GB kernel.

[Q] Which ROMs and kernels are compatible with 2.22.27.08 radio?

I tried nandroiding back to ezterry's rooted aosp but it uses a cm6-based kernel and therefore boot-looped me. I didn't want to flash back to 2.22.23.02.
I want to use the new radio for the alleged extra memory that it frees up.
Thoughts? I rooted the ota froyo and overclocked it. I'd like flash a kernel to OC more, or maybe try a different rom so I can play with swap. I just want to stay on the new radio.
Thanks!

just flash the kernel from the OP to any rom. It should work. Not sure it will work on CM ROMs though.

Interesting... most of the ROMs around here are CM based though, such as biffmod, Tmus, etc.

[Q] Custom Rom Upgrade / Downgrade

Hi pp.
I have a question about applying custom roms. I have my A500 with Virtuoso Galaxy which is 3.1 based and i want to know if its safe to switch to a 3.2 based rom.
It's necessary to do something before? Or I can apply the rom via clockwork without doing anything? (I've already did a backup from my stock)
Sorry for my English, I know its horrible xD!

Yes, just wipe in CWM and flash it doesn't matter what you had before.
Great! I did it without issues. But, now, just to know, It's possible and/or safe to downgrade to others roms from 3.2 to 3.1?
Thnx!

Since you are rooted then yes, it is completely possible to downgrade to older ROM.
Yep, You can pretty much move between roms (3.0-3.2) freely now. Just make certain you wipe before flashing new roms to lessen the possibility of hang-ups or issues with new roms. You can also try different kernels too just make sure they are compatible; most devs will post compatibility in the thread. Hope that helps.
Enjoy!

[Q] Another reverting question...

I'm tired of looking for an answer to this seemingly simple question on google and searching on here. I've had at least 5 tabs open for the last hour combing through posts and replies.
Question is this: A500 running thor's v14.2 rom along w/ his custom kernel. To revert back to stock. Do I need to flash back to the stock kernel along w/ the stock rom. If so, where can I get the kernel from?! The closest thing I came across was a post that gave the source link where you had to build the kernel yourself.

did you make a nandroid of your ROM before you flashed the current ROM youre on?
of course not! lol. I was too excited to play around w/ it that I neglected the basics. And honestly, I've been putting off reverting back because I'm quite happy w/ thor's rom.

thanks! I found out that thor's kernel is supposed to work w/ the stock rom. so I'm just going to try loading a rooted stock and hope I don't brick it.

good luck bro!
I've also decided to head back to a stock ROM in both anticipation of the ICS update and to try and get video working with Skype. My problem is, I'm using a A501, which seems to be the unwanted red headed stepchild of the Iconia family!
I'm on a custom ROM (Moscow something-er-rather?) with CWM. Do I just find a copy of the stock ROM and flash like a custom? I just really want to be able to get OTA updates and hopefully solve my Skype video issues...
Thanks in advance!

I see vache has a couple Full 3.2 Stock 501 roms on his thread here :
http://forum.xda-developers.com/showthread.php?t=1113878
i got a a500 and i assume you extract the update.zip and flash as per a500. Dont wanna put u wrong tho' so maybe ask moscow on his rom thread, he da man when it comes to the 501
Okay - I'm going to try and flash that update.zip and see what happens. My biggest concern is the lack of Skype video - I can only assume it has to do with the ROM flashed, and nothing else, because other people claim they are able to use Skype video.

[Q]What is the most stable and safest official gingerbread rom for Ideos X5?

First of all sorry for the noob question, because I'm really a newbie in this kind of mod.
Ok let's get to the problem. My Ideos X5 is running on Froyo,and wanna upgrade it to official GB stock roms.
After reading and searching in this web, I knew that some users found trouble after flashed it with the stock(can't go to pink screen, can't root, can't instal CWM, and the worst is it bricked their phone etc).
the reason why i'm gonna ugrade to official GB instead of straight to instal custom rom is some rom requirements need my phone to be upgraded into official GB. But then I've found many kinds of stock roms in the web such as B526, B138, B528, B16. since this situatian has turned my will to upgrade my phone, I just wanna know what is the most stable and safest official gingerbread rom for Ideos X5 out there, that won't brick my phone of course.​thanks for the responds/advices

It is very difficult to brick your phone, I have to tell you, if it's possible.
I installed dozens of ROMs, some very good, some others plain bad, and my phone still works perfectly.
Today I am using Dzo's excellent ICS Aurora 2.11a which makes my friends envy my phone and has none of the GB bugs.
So, my advice is try some ROMS and find for your self which suits you best.
Thanks a lot lateris....
so what should i do first? instal the official rom first or straight to the custom rom (miui/cyanogenmod etc) cus some recent custom roms require my phone to be upgraded into official.
At the moment, you could try EZET's cyanogen custom rom if still on Froyo. It is cm7.2 based which is gingerbread 2.3.7 and it is very good. Runs fast and is very smooth. AFAIK everything works now, even tethering.
Otherwise you should upgrade to official gingerbread first if you want to get the ICS based roms that are here (like Aurora) or are in the works. I would use b526 as it is the last version to be able to root easily using superoneclick root and then install custom recovery and custom roms.
Most of the phone brickings with the official update happened because of custom partitions being installed and updating using the beta gingerbread release, you should be fine to update safely if your phone is still on official froyo.
that means a lot Mr. Paul....thanks 4 ur advice

I agree 100% on that, all phone companies makes unstable roms, and custom roms ALWAYS BETTER.

I believe it is difficult to root B528. Of the two, I suggest you use B526

It's very easy to root B528. You need B528_root.rar from somewhere in forums. Try search general section.

Do you need Gingerbread specifically? The Aurora ICS ROM is already stable and there are no major bugs - sometimes the mobile internet connection does not work until the next restart, but this problem already existed on Gingerbread too. Device encryption does not work either.
The ICS ROM one of the fastest ROMs for this device, I see no reason to install an older version on purpose.
Once again the process:
1) Install a official huawei gingerbread ROM, this is done to update the kernel. You need this for the newer ROMs. This is done by putting a update file onto your sd-card (into the dload folder), instructions are provided by huawei.
The first step simply is done to update the kernel, this happens automatically. Be careful though, you want to use a specific file and not the newest version from huawei as this complicates things. If you do not know which file to use I am happy to provide you with a link.
2) Start the phone when the update is finished. Follow the setup, do not configure a wireless connection, google account or anything else. When you are at the homescreen, attach the device to your computer and remove the dload folder, the update is already done. This step is important.
3) Now you install a recovery program that manages your ROMs (make backups, delete ROM, install new ROM etc.). You use this here, instructions are included and should be easy to follow: http://forum.xda-developers.com/showthread.php?t=1377390
4) Try to start the recovery mode and see if you can move up and down with the volume buttons (at the menu). Now you have the updated kernel and a working recovery program, that is all you need.
5) Download the zip-file of the ROM you want to use (I suggested ICS earlier) and copy it onto the sd-card. Within recovery mode you can now select the zip-file (do not extract it!) to install the new ROM. Before you do that, you select to wipe data, cache and under advanced the dalvik cache. This is important.
Now you have to wait quite a while when the phone starts for the first time with the new ROM. Just wait a few minutes and do not interrupt this. You will be greeted with the setup screen of your new ROM and can now configure wireless, google account etc.
XphX
XphX, and how about rooting? Don't you need to root your phone first? (I'm a leek)
You do not need to do that, the ICS Aurora comes pre-rooted and the other custom ROMs come prerooted too - just read their description.

Is there a differences between the 2.2 and 2.3? non-kernel

What are the the major difference between 2.2 and 2.3, besides the kernel and other software stuff?
boot image, emmc, partition table, that kind of stuff.
Also why exactly do we need to downgrade via the official to switch the kernal? Does the official update make modifications to other stuff that CMW can't?

Major difference is one Android version up. The looks of the UI are completely different, but under the hood you won't notice too much difference.
Regarding kernels, you only need to change stock 2.2 to 2.3.5 and vice versa when you install ROMs based on .32 and .35 kernels respectively. Ics also needs official 2.3.5 installed first too. There's no way to install a .35 kernel based ROM over a .32 ROM, you'll have no network service.
The underline reasons are too technically for me but that's how it works
One last thing, if you plan to only use stock ROMs, keep the 2.2, the 2.3.5 betas are a pile of crap.

Thanks, but what I'm trying to find out is the under the hood stuff. I can get 2.3.5 working, and I can usually get 2.2 working. However I can't get 2.2 custom roms to boot, they all get stuck at the boot logo, and I'm trying to figure out what the problem is. 2.3.5 custom roms work, and 2.2 stock roms work, but 2.2 custom roms don't work.

Make sure you use correct cwm version. For .32 ROMs, you need cwm 5.0.2.6, for .35, you need 5.0.5.4. It has to do with changes in partition scheme between .3á and .35 ROMs, if I'm not mistaken.

Thanks for the advice.
I was thinking along similar lines, but backwards. I had been using 5.0.2.6 and thought maybe I needed to switch to 5.0.5.4. Neither work. I've got a feeling it is partition scheme related. I just got done fixing my partitions after the "resize the internal sd" thing messed up at least my data and internal sd. Maybe I haven't fixed it completely.
I also found that installing .32 MIUI causes something to change in my data partition. Before installation, ubuntu sees my data partition (via pink screen) and can open it. After installation, ubuntu won't open the partition, saying I don't have permission, or something like that. After I double check it, I'll take the question over to the appropriate thread. Haven't checked other custom roms to see if they're doing the same thing. Maybe they all are and that is what is causing them to be stuck at boot.
