Download the radioZUI2.5 rar file from this link >> https://drive.google.com/drive/folders/0B_e7IyAKmSLcTE0wdXcxdDhFb2c
Extract the file, reboot into fastboot mode, run the flash_radios.bat and follow onscreen instructions. You will need to install adb and fastboot on your pc first!

leave all that...unless you either s-off or unlock your bootloader you cant go ahead rooting ur phone..follow the below method which i find is easiest::::
#1 unlock ur bootloader using htcdev method(www.htcdev.com) (remember this will void ur warranty).plz do watever is mentioned step by step on the site....
#2 after u unlock bootloader u will still have s-on but ur device is now rootable...
#3 root ur device using unlockroot one click tool (www.unlockroot.com) and u will have root access superuser installed..congrats u r now rooted
#4 installing clockworkmod recovery on your phone via fastboot method (plz dont use rom manager to install cwm recovery as it just provides a temp recovery)..just do it via fastboot method (scan xda forum on how to do it via fastboot)....done ...u r ready to flash a custom rom...
#5 download any custom rom for wildfire (ex:cyanogenmod 7.1.0.1 buzz)and place it on sd card...turn off ur phone and reboot into bootloader and select recover,,ur device will now boot into recovery..then select install zip from sd option and choose the rom file...congrats ull now boot into a custom rom...(dont forget to backup ur existing rom )..hope it does the job for u....

Xperia Arc S Unbriked With Sucess

Hi guys i want to share some information who was useful for me with Xperia Arc S 12w07 :
Important : Dont make normal updates with SEUS ou PCC if your phone was unlocked by other tool, because you will brick the phone, you need to start using other firmwares, but ask for opinions first..
After Alejandrissimo unbrick my phone, the phone ask me to do update to new version, so i click yes to make thet update, and after 5 seconds gave me one error in update, so my phone was dead again with yellow triangle with one phone, so i talk to alejandrissimo again and he gave one file to fix the phone again with Flashtool, so i will share with you ok, but i think i already saw this file in other post..
Steps :
1º - Install Flashtool - flashtool-0.9.10.1 - http://forum.xda-developers.com/showthread.php?t=1000012
1.1º - Google and find this file : " [Xperia Device] flashmode & fastboot driver bundle " and install all..
2º - Install all Drivers
3º - In flashtool be sure if the drivers already installed, sometimes the file install but in pc need to install more with the phone connected
4º - Select Flash Mode
5º - Put the fix file in folder firmware of flastool, and you can delete the other file x10 in the same folder you dont need.
6º - In " Program Files\Flashtool\devices\LT18 " you have this file loader.sin, when you try to flash if he give this error : " cant find loader_unlocked.sin ", then you need to rename the " loader.sin " file to " loader_unlocked.sin", and then flash again, and will work..
If was simple bick like my phone it will be fix it, maybe for other phones is the same, check the devices folder for the files and if you need to rename like i did...
Hope this help for some people ok..:good:
Now i need to update to new version of android, but i need to see what is the correct file to flash or i will brick my phone again..
Tks to Alejandrissimo again, he teach me to do that.. :fingers-crossed:

Factory reset
Have you tried factory reset?

Have you tried factory reset?
Click to expand...
Click to collapse
yes i have already done all the things like factory reset
I've got the same problem.. IMEI lost after flashing P6 to MIUI ROM. Any info about any app that can repair it?
Is the IMEI of the P6 is on a rewritable memory? Or It's just can't be detected by the MIUI ROM?
I'll only receive the device today, so I couldn't check anything in it. But I think the first step will be to flash it back to a stock ROM...
Still no useful info about this problem?
I fleshed it to an official (B125) ROM, but have the same results. Could someone tell me the correct number of the official Kernel that the P6 was shipped with? As I already wrote I got it as a used phone with these modifications, so I've got no idea what did it look like in it's out of the box state.
Thanks!

hi all this worked for me you can try it too
okay guys you can try this it worked for me, download huawei update extractor and install it. also download minimal adb and fastboot and install it.
I'm not a pro at this so research how to install minimal adb and fastboot if you don't know how to.... after this you download a custom rom or stock rom for your device ( that is if you don't already have one) .....
if you have the zip file just extract modemimage.img and place it in the folder " minimal adb and fastboot" if you have an 'update.app' file then you will have to use huawei update extractor and extract the 'modemimage.img' file and place it in the folder " minimal adb and fastboot''. This folder is located at mycomputer/program files/minimal adb and fastboot.
Now, open adb fastboot via command prompt or click the shortcut on your desktop, type
" fastboot flash modemimage modemimage.img" and it should now say " waiting for device " . turn off your phone . when its off connect it to your computer, now press and hold the power and volume down button together until you see connected/okay on your pc screen . when its done flashing the file it should say okay. .. and thats about it.
Now turn on your phone and the service should be working now and you should see your imei and baseband is back.... if your wifi is not working just do a quick wipe/format from your twrp recovery and everything should be working fine. this worked for me hope it will for you too. Good Luck

Hello,
Please provide your phone's CID & MLDELID. To solve this problem, you need to either restore a stock firmware & stock twrp backup, or flash a stock RUU. Either way, the firmware & software must have matching cid & modelid.
As of right now, the data you posted indicate that your phone has mismatching firmware & software (x.xx.708 and x.xx.709).
Cheers

You can't just flash any file you please. RUU & firmware you want to flash MUST be specific for your device's region and variant model - in your case, you must flash ASIA-HK-CHT firmware & software. ATT & CINGULAR are US specific, and will not flash on your phone without modifications.
Instead, download the 1.60.x.x from the link provided by @Jerrel7, and the TWRP stock backup from 1.60.708.x provided below:
https://mega.co.nz/#!e8AFCCQZ!2-2Lx1vxkg1xBq_Yhg_Sk9AOzdZsPrX2oOlxy-PLTF0
Flashing the 1.60.x.x firmware and restoring the 1.60.x.x twrp backup will put your device in a stock condition that will allow you to receive official updates from HTC.
Cheers
P.S. let us know if you need help restoring the backup or flashing the firmware.

Hello. I had the same problem. Just solved it yesterday. The whole problem was in my MID. You have to change it for the RUU you want to install.
I was with MID for Singapore and i wanned to install European version. So i can't install the updates. After i changed the MID now i'm able to install every update.
Just follow this thread and you're done. Good luck, mate!

@Mike Smaan problem is a bit different from yours and he has a S-On device.
His problem is his device is running a Taiwan ROM on a Hong Kong variant device.
He needs to run a Hong Kong ROM to solve his problem and the right ROM version (4.18.708.12)
then he can OTA to the latest Marshmallow 6.16.708.1
Should he followed the link provided by @Jerrel7 on post #11, he should be able to fix his problem as simple as ABC.

Very well. Assuming you downloaded the twrp backup and stock firmware from my previous post, proceed as follows:
1. Download HTC Sync from the link below:
http://www.htc.com/uk/support/software/htc-sync-manager.aspx
If you already have HTC Sync installed, then upgrade it to the latest version. Otherwise, install the one from the link provided.
Reboot your PC.
2. Download the FASTBOOT PACKAGE from the link below:
https://drive.google.com/file/d/0B8L4pkbzdlR3eTlJSjdKVEdHX1U/view
Extract the file to "c:\fastboot" folder.
3. Download twrp 2.7.0.2 from:
https://dl.twrp.me/m8/
Extract the file to "c:\fastboot" folder.
4. Put the 1.60.708.x firmware zip you downloaded from my previous post into the "c:\fastboot" folder but don't extract it.
Summary:
You should now have:
A. the latest HTC SYNC installed.
B. A folder called fastboot in the root directory of your C:\ drive.
C. Your fastboot folder has the following files:
I. twrp 2.7.0.2.img
II. The zip file for 1.60.x.x firmware
III. htc _fastboot.exe
Let me know when you're done.

There are 4 easy steps to accomplish the task:
1. Flash twrp custom recovery. 2. Restore the twrp backup. 3. Flash the stock firmware. 4. Profit.
Let's get down to business:
1. Flash twrp custom recovery:
A. Boot your phone into fastboot. You do this by turning your phone off, then hold Vol- and power button. You're presented with a menu, choose fastboot (navigate the menu using vol+ and vol-) and press power to select.
B. connect your phone to your PC. Open a cmd window:
Type:
cd c:\fastboot
fastboot flash recovery twrp-2.7.0.2-m8.img
Flashing will take a few seconds, when its done, type:
fastboot erase cache
Now, on your phone, select "hboot", then "recovery", to boot into twrp.
2. Restore the twrp backup:
Unfortunately, twrp doesn't immediately create the directory structure for where you'll put the backup file you downloaded. So, we're going to start by creating a backup of your current ROM:
A. Select Backup button in twrp. Select "external sdcard" from the menu at the top, and proceed to create the backup.
B. On your computer, extract the twrp backup file you downloaded, and copy the extracted directory to your phone's sd card. Put it in:
/sdcard/twrp/backups/"serial number"/
C. On your phone, tap restore, and choose the backup directory you just copied to your sdcard. Proceed to restore.
D. Choose to restart your phone and select Bootloader.
E. Select fastboot.
3. Flash the stock firmware:
A. On your PC's cmd window, type:
fastboot oem rebootRUU
B. WAIT UNTIL your phone displays black screen with HTC in white, then type:
fastboot flash firmware M8_1.60.708.2.zip
C. Once more, type:
fastboot flash firmware M8_1.60.708.2.zip
D. Reboot by Typing:
fastboot reboot
4Profit.

I know that you ignored my previous posts and other people post who tried to help you with proper method .. but I still pity you and I don't want to see you'll end up in a brick or soft brick due to wrong commands/instructions.
You get error when flashing firmware - reasons :
1. That command given to you to flash firmware - fastboot flash firmware M8_1.60.708.2.zip - is wrong.
The right command is fastboot flash zip M8_1.60.708.2.zip
Running a wrong command may brick your device but you are lucky because your device is S-On, so no harm just error.
2. Being a S-On device, you won't be able to install a very low version firmware 1.60.708.2 when your current one is 4.18.708.12
Only S-Off device can do that. To have S-Off you need to spend USD25 for the app .. and are you willing to spend USD25 to S-Off when you can fix your problem with proper method free of charge and needs only 2 main steps : ?
1. Restore 4.18.708.12 TWRP backup
2. Install 4.18.708.12 stock recovery.img
then you can update to the latest - 6.16.708.1

You can try these B., C., and D.
But, again using a very low version 1.60.708.2 backup on a Lollipop firmware 4.18.708.12, you may have one of these :
1. It will be successful updates but you need to do many OTAs
1.60.708.2 --> 2.11.708.2 --> 3.32.708.4 --> 4.18.708.12 --> 6.16.708.1
If it is successful then it's good but if it is not, you'll get below.
2. You may have a blank screen either between OTA 1.60.708.2 --> 2.11.708.2 or OTA 2.11.708.2 --> 3.32.708.4
3. You may lost your wifi connectivity either between OTA 1.60.708.2 --> 2.11.708.2 or OTA 2.11.708.2 --> 3.32.708.4 but you can proceed further with your mobile data or use a Internet Pass through on your PC
One last note ... never use a 2.7.0.2 TWRP recovery as that is the most buggiest TWRP which will remove your OS version on your bootloader.
Good luck.
