Check phone version / exact sub-model, here are three hardware versions of Y300:
1.Huawei Y300 (T8833) - TD-SCDMA / China Mobile
2.Huawei Y300-0000 (U8833) - WCDMA China Unicom
3.Huawei Y300-0100 (U8833) - WCDMA International
check version (product ID) with this code : *#*#1357946#*#* , dial button (green)
there is international version ROM - Y300-0100 at Huawei site, you probably downloaded it ...
- put "dload" folder from archive on formatted micro-sd card's ROOT
- put micro-sd card into phone
- start phone in download mode = Press the VOLUME UP and VOLUME DOWN key, and then press the
POWER key to power on the phone and enter the Software Upgrade Mode
(taken from upgrade manual - which is found in archive, pdf ... )
- wait for finish ...
p.s. if not accepting firmware - means it's not international version ....
I have HUAWEII Y300-0000 phone I've bought in china.
Managed to unlock it thanks to your manual.
It comes with ROM: Y300-0000V100R00C17B180 (Android 4.1.1).
The only problem I have is that sometimes when I try to dial I do not manage to establish call (the call is tried to be established and then disconnects). When this happens there is also problem in incoming calls. I manage to receive the incoming call but when answered the connection drops after several seconds.
My question is whether this is an issue you are familiar with.
If so, do you have any suggestions?
Are there any new ROMs for this version that maybe handle these kind of issues.
How can I install new ROM on already rooted phone?
