Flash roms on LG Optimus 7

Is it possible to flash roms on the LG Optimus 7 in any way? I don't mean custom roms I just want to flash an official release build on my device.

How did you loose your official release rom that comes with the device?

I never had it. I'm using a pre-release device with 6536 build.

Then, I think you might need to wait for the first update, as there really isn't any ROMs floating around the web for Optimus 7 yet...

I see no developers who care about optimus 7, so sad. Such a nice phone.

Not true. There may not be any development topics here. However, in the actual WP7 Development forum on XDA, most of the modifications and hacks apply to the Optimus 7 as well (with the exception of the HTC specific or Samsung specific ones, duh!)

There's new thread in the development forum for this device. Teaches you how to flash the firmware along with the correct firmware for specific countries.

Take a look here and use the firmware you prefer )))

Hi all,
I am trying unsuccessfully the method mentioned above without any success since yesterday night.
If followed carefuly the steps but when launching "LGDP2_V36_UMTS.exe", I can't enter Emergency Download mode.
Everything is well installed, my modem was located in port COM4, I have the correct DLL and .dz rom.
But when I press the "Start" button, and plug in with the USB the phone when LG logo appears at startup, nothing happens.
If I set the "USB Switching" to QC Composite, using MFG, when connecting the phone, ports COM5 and COM6 become active (still nothing on port COM4) in LGDP2_V36_UMTS.exe, I get "ErrNum502 EMERGENCY MODEL FAIL" after a few seconds.
Any idea on this? I am currently running an LG Optimus 7 under NoDo Orange-FR branded (would like to flash with the European rom).
Thanks in advance.

The roms available for download are for 7004. As far as I know, you cannot flash the older version rom atop the newer OS. Your best bet is to reverse the nodo update with Zune, then attempt to flash the desired rom.

Hi Kapanak,
I see, thanks for your reply. Do you know how to "downgrade" my phone using Zune? I went through the whole parameters and sync list and found nothing.
Thanks,
Thomas

Go to settings>phone>update on the computer you did your NoDo update. There, you will see a "backup" prior to updating your phone. That back, when you phone is connected (make sure of this) will restore 7004 to your phone. Make sure you save everything on your phone before doing this, as you WILL loose everything acquired/synced/changed on your phone after NoDo update...

You can flash which rom du you prefer, sure you can downgrade 'cause this will erase ALL the partitions on your mobile.
DOWNGRADE with flash is SAFE, it's just a waste of time to reverse with zune and then reflash.

@ kapanak:
I guess I had not option to downgrade using Zune as after the Nodo update, I deleted the entire folder Zune created for the restauration point on my computer. I hate softwares using 1.5Go on my hard drive for "nothing" Guess it was a mistake here...
@ the.rider1290:
Based on your post, you mean that even running Nodo, I can flash directly using the ROMs available for download here? And this would downgrade automatically my phone from Nodo (Orange FR linked) to the previous WP7 version Europe free (I chose this one)?
So, any idea on what prevents the software "LGDP2_V36_UMTS.exe" enter my phone in Emergency Download mode?

Not true, I unknowingly flashed a StarHub ROM on my Optimus 7 before the 7720 ROMs were released. My phone was on 7.10.7720.68 and backtracked to to 7.0.7004. Microsoft stopped delivering old updates so i was temporarily stuck on 7008. Then i used ChevronWP7 updater to update to NoDo, then used the beta update to update to 7403, then got a notification for official StarHub update, followed by a LG software update, then a "family and friends" update to clear some crap, then the 7740 update. entire process took 10hrs.

Just install the modem driver then plug in your phone in emergency download (VOL-CAM-PWR) then if using Win Vista u will see "Installing driver device software" then click the balloon and see which COM port it is (e.g. LG Device (COM #21)) then choose THAT port and start. having the "Can't find monitor port!" warning is ok.

Reflash
I need a step by step tutorial on how to reflash my lg optimus 7 e900h.. it keeps restarting and when i sent it in for repairs all they did was relfash it. Reflashing seemed to help at least for a month or two, but now that my warranty is up i need a tutorial! anyone please?!?!

Issues installing official Tango Rom from Verzion

Hi guys i'm trying to update my Trophy to the official Tango release and i'm getting error number
80180048
There was an error while trying to update your device with the latest software.
Please try again.
Cannot update to highest version.
I've tried everything trying to get the update and nothing seems to be working.
Any suggestions.
I've hard reset and soft reset the phone i've reinstalled Zune and i've called Verizon, HTC and Microsoft for a solution and none have been able to help.

Is your phone unlocked?
Using a custom ROM?
On official firmware, with NO modifications to anything?
You can't update with any modifications...
Tapin' the Talk on the HTC Trophy

I'm on Stock offical Verizon Mango update. I've got no modifications at all was never able to unlock the phone.
OS version 7.10.8107.79
Firmware version 2305.13.20402.605
it's the 16 gb version if that helps.

Did you try to unlock before? Maybe your bootloader is messed up?
Sorry in not much help... You could maybe download the NoDo flash and re-upgrade through Zune.
Tapin' the Talk on the HTC Trophy

Thanks Peperm1nt nothing so far has worked. But thanks for trying.

How did you install 8107? Did you force install the updates, or Zune update? Or did your phone come with 8107? I had issues getting my test VZW Trophy to update completely over Zune. I say, take this opportunity to install HSPL so you can have custom unlocked roms, and wait for a nice official Tango release.
Or you can try the Microsoft troubleshooter.. which basically says for error 80180048 to download and install the Windows Phone Support Tools and run some stuff. Try it, maybe it will work...
Or, you can follow my guide to get the phone unlocked once and for-all and BREAK free.... although I gotta revise the guide for tethering stuff with the official updates (which you would want to setup BEFORE installing a custom unlocked custom rom).

Flash Chinese Rom on Honor 7EU

Hi to all,
Ive been reading a lot this forum, and i find the chinese version more complete, so my question is simple.
¿is it possible to flash a chinese rom? I like chinese features, and i read it gets more updates.
My only worries are warranty and to lose european radio bands.
Any help?

Give it a try and let us know how you get on....;0)

Thanks for your message sheridan2000,
I'm a newie, until now I only had a nexus 4, wich have a huge community, I don't know how to do if for this new phone I just received, and I'm worried about the warranty, about brick if and if is possible get back to EU flash rom.
My abilities are limited, and with my lack of knowledge I feel is too risky.
If some one with experience can bring some information would be great.
Regards,

Just kidding fella, think at this early stage in developement best not to flash any roms not intended for the EU version as may mess up your phone. When we get a fully working ROOT and TWRP then there will be some safety in doing so....

Agree with him! When we get a stable and well working custom recovery, I think people will mod the Honor 7 more.
Any why do you want the chinese version? I tried a chinese MIUI rom on my Honor 6, and the all the chinese stuff drove me crazy so I had to roll back to a normal EU rom...

Hi!
I feel like chinese rom is more "updated" I think european version is more "conservative" as they might try to secure the user experience. Chinese rom gets much more updates, Ive read something about huawei idchanger; Chinese rom also have more options like recording call, navigation shortcuts, youtube bloat window and download...
In nexus we could chose wich part of the rom we would like to flash, is that posible in this huawei? What I have thought is what about flash the Chinese rom, without flash the radio baseband in order to keep the compatibility with european LTE bands. Any idea??

I did this on my european honor 6 plus. DO NOT DO IT.
No way to get back to european firmware. But was probably because officallollipop was not out yet. More hassle than it was worth. Voided warrenty also. DO NOT ATTEMPT

Thank you for your usefull feedback.
I hope soon someone finds a safe way to run and revert back this kind of test.

One question: you had the complete nandroid backup and you couldn't flashed it after experimenting with the Chinese ROM over EU? How far did you get then or where did you stuck when trying to reverse?
I never had EU Honor 7, but my personal opinion is that before playing with different roms, you should be perfectly aware what are you doing and what do you want to achieve. Changing hardware is out of the question and probably is the same with drivers. At least to the point when a real custom rom appears. As I mentioned there are some modifications of Chinese roms already available as a flashable zip, which don't alternate baseband or kernel in general, but they are customized to particular roms. Flashing any of them on EU rom could be safe only if you can get back in the case anything goes wrong. Otherwise, if you just need a particular system application, you can always try to push it to the system with appropriate file manager and stay safe as long as you have the nandroid backup.

Nandroid backup did not work through twrp.
Chinese rom was fine but was a developer edition.
Phone can not go back to kitkat from chinese lollipop.
Tried offical downgrade package. Did not work.
Tried back up many times. Did not work.
Chinese emui site takes hours to load and most of the time fails through multiple browsers.
Dont waste your life.
I was still in my 14 day return so exhange by my network to honor 7
Never messing with a huawei phone again where there is little to no support

i had tried chinese rom PLK-U00 which is DUAL 4G as per claim by Honor China, what i do is i extract out the boot&recovery&system&cache&userdata img from the update.app (using huawei tools) then flash it under fastboot, it will boot & load to "Android is upgrading" but after the progress finish it restart itself and repeat the "android is upgrading" progress

I've tried the same with 5.1.1 ply-tl01h rom. I get the bootloop with boot and system flashed and almost get to the home screen using the boot from the 121 firmware

Hi,
I hope you could find a way. I know there are chinese roms available, but hard to find and understand, we might ask them in english then they might help us.
I hope you could fix your phone

Hello Guys,
I bought my Honor 7 yesterday, and this is the model number -- PLK-L01C636B120
I tried to update to B121 or B130 or 140, All of them failed.
As I read my device model is Malaysia not Europe, So Can I flash Europe Stock ROM and flash all the updates?

NO i don’t think so! You should do not do that, because there are some differences between both firmwares. Pre-defaults for the mobil-net (modem drivers) ; LTE specifications; maybe some functions like recording during a call etc.
Edit: @Muhammad Rihawi have tried it and it seems to work. But i dont’t recommand it anyway!

Should I update my Firmware or Modem?

So just because of curiosity I decided to check sammobile and see if there were any new Firmware/Modems on the site. To my surpise their are. I was wondering if it was suggestible to flash if so, is there an easier way then register though the site and having to use KIES? Currently running CM12.1 planning on making the move to CM 13 when they support ExFAT.

If you want to download firmwares I suggest you use this program. Way better then sammobile.

Other then that, if you are running Lollipop bootloader and modem and everything is working fine, then there is no point in updating those parts.

Which ROM to install now on YB1-X90F (android)

Hi. I've never really liked the Android version in my Lenovo but I am now facing an annoying issue with Play Store downloads getting stuck and delayed and going to have to reinstall.
At this point I am ready for a root and changing the ROM but I am rather lost in what android distribution are working and tested at the moment as after reading for a while there are some which are only for the Win version. I also see some references to X90L on threads about rooting and installing twrp but I am assumming these would work the same on my F version.
So the question is, what updated current ROMs are working fine and are worth (better than the official one) after root and TWRP on the Android version?
Also, once unlocked and changed bootloader, where can you get the official ones again?
Thanks for any help.

"Also, once unlocked and changed bootloader, where can you get the official ones again?"
You don't need it if you flash YB via Intel Flash Tool with oryginal rom.
