im having a couple of problems. when my phone turns on it goes straight to MAGLDR and says SD KERNEL OPEN FAILED.i have read numerous threads and still dont understand what i should do about this. the next problem is when i try to unzip a rom it says the "installation aborted" i would very greatful if u could help me get out of the MAGLDR menu and back to having a working phone. i have tried to flash back to a stock rom but i cant get my phone to connect to active sync. i have been struggling all day and cant figure out where i went wrong and i need your help please. I cant get out of MAGLDR at all and all i want is to flash back to a stock rom or any rom for that matter so i can use my phone again. Im sorry for creating a new thread because i know alot of people are having similar problems but i couldnt find an answer.
thanks adam
You need to flash ClockworkMod Recovery with the appropriate size system partition for the nand rom you intend to install. Flash the recovery from your pc with MAGLDR in usb flasher mode. Then in MAGLDR choose AD Recovery, and in recovery, choose 'install zip from sd', then pick 'choose zip from sd card' and choose the zip that is the rom you wish to install. Dont unzip it, Clockwork Recovery installs from .zip files.

im looking to flash HD2_NDT_MIUI_FROYO_ROM_V6.2_Multilang what would be the proper CWM recovery v1.3??
150 mb for that rom

im not sure what u meen by partition size how do i select that and do u know of a way i could connect to active sync so i can just flash stock rom. in MAGLDR i havnt found a way to connect to active sync. any suggestions on how to go back to stock? thanks for helping.
Power your phone on while holding the vol down button. Your screen will have 4 colored bars. You can flash a stock rom from there. Your phone won't connect to ActiveSync or Windows Device Center while in this mode, but the stock windows rom will flash.

No problem, glad your phone isn't wrecked. If you still want to use Android, but don't want to mess with flashing it to your phone's internal memory, you can always use sd builds. Then you still have WinMo, and you can even have multiple different Android builds on your sd card, in different folders, there are programs for Windows Mobile that will even launch Android for you and let you choose which build to launch. It's alot simpler than flashing nand roms, just drag n drop a folder onto your sd card and bot into WM, use File Explorer to navigate into the folder, tap CLRCAD and haret.exe , and Android launches.
Hi!, how i can revert, all changes and return back to my stock rom&kernel. After that, i will unroot my phone. Are there a way to do that easily?

Or, if you did your nand bakcup, restore it with recovery. and you go back to original rom from your phone.

Yes, but then you won't have the stock recovery. It also won't be 'stock' because it has probably been rooted and apps removed etc.

It's unrooted if you restore a backup before you rooted your device.
Here's the thing. I want to go back to the stock ROM but I didn't do a nandroid backup. Stupid of me, I know. Anyway, I got from a friend the stock recovery.img(3.0.2.8) and also the stock ROM (U8800V100R001C00B135SP02(WIND-HELLAS)). It is a greek ROM. I applied the recovery.img and now I'm downgraded to 3.0.2.8 from 4.0.0.5. Then, I booted in clockworkmod and tried to apply the stock ROM's .zip . However, I get "Installation aborted" message all the time. I cannot understand where I'm wrong. Maybe someone that did return to stock ROM can help me out here.
edit: Sanpsa, you said that someone should follow the instructions of the extracted files. You mean "UPDATE.APP" and "UPDATE_CUST.APP" files? In my stock ROM with these files you can upgrade the ROM. Is it necessary to upgrade the ROM and then apply the .zip? I don't get it...

If you want the stock Rom back, follow these exact steps:
1 - Go into the Bootloader (pink screen), put the recovery 4.0.0.5 back.
2 - Take out the battery to exit Bootloader (pink screen)
3 - Press Vol+ and Power until you boot into Recovery.
4 - In Recovery go to Mounts and Storage, connect the USB cable and select the last option Mount External Storage (SD Card)
5 - Use the computer to explore the SD card now, Create a folder called "dload" and put both files "update.app" and "update_cust.app" inside the folder.
6 - Disconnect the cable and select the option Power off.
7 - Once the phone is switched off, press VOL+, VOL- and POWER together for 5 seconds.
8 - This should start the automatic installation and you will have your stock Rom back in 5 minutes.
Cheers

These files are not present in the (U8800V100R001C00B135SP02(WIND-HELLAS)) ROM. Only in "overseas". So, I cannot proceed.

Strange, as all stock Roms come as zip archive with these 2 files inside. Are you sure that's a stock Rom?
Did you actually unzip the U8800V100R001C00B135SP02(WIND-HELLAS).zip ?
To give you an idea...
I did these exact steps
1. Installed recovery 4.0.0.5
2. Copy/paste the images ".android_secure", "cache", "cust", "data", "system" and "nandroid.md5" from (U8800V100R001C00B135SP02(WIND-HELLAS)) ROM to mnt\sdcard\
3. Booted in recovery
4. "Backup and restore"-->"restore"
So, into "restore" there is only one backup file from a previous ROM, which btw I don't know how to get rid of it because I don't need it anymore. I can't find any "delete" selection or something.
edit: Yes, I did unzip it. This stock ROM was uploaded by a fellow Greek to provide assistance in such situations. Nobody else complained about his upload for not working.
edit2: I found how to delete backups!
SOLVED!!!
I just pasted the ".android_secure", "cache", "cust", "data", "system" and "nandroid.md5" files into /sdcard/clockworkmod/backup/ and did a restore one by one. AT LAST!!!
Warranty is on...again!

FYI, what you have is not the stock rom, rather a nandroid backup of the (presumably) stock rom..
thats why the steps to restore are totally different in these 2 cases..
anyway glad that u got it sorted out..

No what he means is that you didn't install a new Rom, you just did a restore from a backup...Which is a totally different process altogether and that's why my instructions were not what you needed.

OK. Got it now!
If u restore a backup from recovery to stock rom, then u still have the custom recovery. I you worry about warranties, then you should also go back to stock recovery. Easiest way to do this is to flash any official rom, these restore the stock recovery also.
Like said, these .zips with the two .app files cant be flashed from any recovery.
I just got the instructions for upgrading the tablet to Factory 2.2 and it just asks you to have a dload folder on the SD card and then press Menu - End and Power together to launch the factory flashing.
My question is: can we just put a Rom in the dload folder and the unit will flash it? Too simple?
No is not gone work.
you can get the dload of a different firmware and it will work that way,
I am currently running one of the CM 7.2 modifications and it does not have an option to launch the update frocess from official update package.
The phone is U8800 PRO. Sadly, I don't have a nandroid backup, it would be dead simple to flash stock ROM backup files and I wouldn't be writing here
So, what can I do? Maybe some of you running stock ROM with "Launch update from SD card" button can share your nandroid? Any advice woudl be appreciated.

download stock gingerbread ROM. create a folder called update on your external SD card. put the update file inside that. now replace your cwm recovery with stock gingerbread recovery. power off phone then
vol up + power button, stock recovery should automatically install the GB update.
*critical that you use stock GB recovery.

That is exactly what I thought, I don't have stock recovery though, this is my problem. Mind if I ask you to share it with me if you have a copy?
I've recently updated my phone to the unofficial CM 13 , and now that the official android 6.0 for my phone is released I wanted to update to it. The problem is that the official way of updating is holding both volume buttons and power button while phone is turned off, but that takes me to the recovery of the installed CM13. I tried flashing the stock recovery, and the furthest i got was that the installation began , but got stuck at 0 %.
Note that when I tried installing CM13 , there was a problem with the package identifying my device, so i searched and found out that i can skip the device check, once i did that i could install CM13, but when i go to about phone in settings , i find that device type is unkown.

How can I flash the stock rom with CWM , because I believe it's only flashable with the stock recovery , and I tried flashing it with the stock recovery but it didn't work .
You dont need the stock recovery. Just boot into CWM or TWRP and wipe cache & davlik cache.
Then power off the phone. When its off hold the power button and the + and - buttons.
When the Huawei Ascend logo shows up let go of the power button and keep holding the + and - buttons until the installation screen shows up.
Take off the case off the phone if you have any.

Whenever I try to do that it gives me an error, the error doesn't even stay enough time to be read.
Just to add that you should have an apdate.app file in folder called dload on external SD card for you to be able to flash it back to stock if you have done that already not sure ??
